A high-precision dispenser, also known as a precision dispenser or automatic cycle dispenser, is an automated device that is primarily used for precision dispensing. The equipment is mainly used in the accurate dispensing of various adhesives, sealants, liquid materials, etc., especially suitable for occasions with high dispensing accuracy, good consistency of dispensing volume and fast dispensing speed.
At present, high-precision dispensing machine manufacturers have Hongdahui Technology. Founded in 2013, Hongdahui Technology Co., Ltd. is a high-tech enterprise that provides precision dispensing, coating, gluing, industrial dispensing equipment, auxiliary material assembly equipment, plasma cleaning equipment and other equipment in the industry.
The working principle of the high-precision dispensing machine is mainly through the precise mechanical structure and control system to achieve accurate dripping and position control of high-viscosity liquids. Its core part usually consists of a mechanical part and a control system.
The mechanical part mainly includes pumps, cylinders, needles, transmission mechanisms, etc. The liquid with high viscosity is transported to the cylinder through the pump, and then the cylinder block is driven by the transmission mechanism to increase and reduce the pressure, and finally the liquid is dripped out by the needle. In this process, the microprocessor controls the pressure of the cylinder and the dispensing speed of the needle through circuitry, so as to achieve precise dripping and precise control of the position of the liquid.
In more advanced three-axis high-precision dispensers, the glue is dispensed at a specified location by controlling the movement of the three axes (x-axis, y-axis, and z-axis). The movement of these three axes is driven by the motor, and by controlling the speed and direction of the motor, the precise movement of the dispensing head can be realized. In addition, multiple aspects such as motion control systems, precision sensors, dispensing head drivers, glue** systems, and programming systems need to be considered to ensure stable performance, high accuracy, and high efficiency of the equipment.
High-precision dispensing machines are widely used in many industries, mainly including electronics manufacturing, automobile manufacturing, medical device manufacturing, packaging industry, construction and decoration and other fields.
In electronics manufacturing, dispensers are used to secure and protect electronic components on circuit boards, as well as to encapsulate semiconductor chips and coat connecting wires and cables. In automobile manufacturing, dispensing machines are mainly used for bonding and sealing lights, windows, body and other parts to provide waterproof, dustproof and shock-absorbing effects. In medical device manufacturing, dispensers are used to apply glue to medical devices, medical appliances, and medical packaging to ensure tightness and hygiene. In the packaging industry, dispensing machines are used to dispense and seal packaging containers such as boxes, bottles, and bagged products to ensure the tightness and freshness of products. In the construction and renovation sector, dispensers are used to fill wall joints, seal windows, door frames, and pipe joints, among other things, providing waterproofing, sealing, and protection.
The high-precision dispensing machine has the following advantages:
1.High precision: The high-precision dispensing machine adopts advanced mechanical structure and control system, which can achieve precise dripping and position control of high-viscosity liquids, and improve dispensing accuracy and consistency.
2.High degree of automation: High-precision dispensing machines are usually equipped with automatic control systems, which can realize automatic dispensing operations, improve production efficiency and reduce labor costs.
3.Multi-axis linkage: The high-precision dispensing machine adopts multi-axis linkage technology, which can realize simultaneous dispensing of multiple points or dispensing complex patterns, improving work efficiency and reducing material waste.
4.Adaptability: The high-precision dispensing machine can be applied to various viscosity liquids and substrates of different materials, such as glass, ceramics, metals, etc., expanding its application range.
5.Programmable control: The high-precision dispensing machine is equipped with a programmable control system, which can control the movement trajectory, dispensing volume and pause time of the dispensing head and motion axis through programming, so as to achieve personalized dispensing needs.
6.Easy maintenance: The high-precision dispensing machine has a simple structure and is easy to maintain, which reduces the maintenance cost and use cost.
In conclusion, high-precision dispensing machines have significant advantages in improving production efficiency, reducing costs, and ensuring product quality, and are widely used in various industries.
The ** of high-precision dispensing machines varies depending on factors such as model, brand, function, accuracy and manufacturer. Some fully automatic high-precision dispensing machines may cost tens of thousands of yuan, while some simple dispensing machines may only cost a few hundred yuan.
Generally speaking, the best range of high-precision dispensing machines is between thousands of yuan and tens of thousands of yuan. The specific ** also needs to be selected according to the actual needs and budget. For more accurate high-precision dispensing machines**, it is recommended to consult professional and technical personnel or contact the relevant manufacturers directly for consultation.
The operation and commissioning steps of the high-precision dispenser are as follows:
1.Check whether the functions of the dispenser are normal, including running, stopping, dispensing, spraying, etc.
2.Test the corresponding switches, buttons, parameter settings, etc., to confirm the normal operation of various functions of the machine.
3.Make sure the glue supply system is functioning properly. Check whether the pressure and flow rate of the glue supply are stable, adjust the relevant parameters, ensure that the glue supply is moderate, and avoid the use of too much or too little glue.
4.Calibrate dispensing heads to ensure precise and accurate dispensing positions. By adjusting the height, angle, and position of the dispensing head so that it is at the right distance from the surface of the workpiece, it ensures that the dispensing glue falls where it needs to be coated.
5.According to the shape and size of the product for dispensing, select the appropriate needle and control distance, control the needle to rise, control the position required for dispensing for a distance, and the needle control distance is always controlled at a distance of 1-2mm from the product dispensing position.
6.According to the viscosity nature of the glue to determine the distance of each focal point, the viscosity is large, the closer the focus separation distance is to prevent drawing and dripping glue (slow speed), the viscosity is small, the glue is fast, the spacing is far, the recommended speed is adjusted according to the actual situation, and the preset point position can not be too far apart, which is easy to cause uneven distribution of glue.
7.In order to avoid the situation that the glue is working before it melts, the glue should be put into the glue valve before dispensing, and the machine should be turned on and preheated for more than five minutes in advance. Avoid glue solid wire drawing and other phenomena.
8.After setting the preset dispensing path of the control box, adjust the preset point position and spacing according to the actual needs to ensure that the dispensing path of each product meets the requirements.
9.Start dispensing, observe the dispensing effect, and make appropriate adjustments if necessary.
10.During operation, the equipment should be kept clean and maintained, and wearing parts such as needles and seals should be checked and replaced regularly.
It should be noted that when operating a high-precision dispensing machine, it is necessary to strictly follow the safety operation procedures to avoid accidents. At the same time, in order to ensure the accuracy and service life of the equipment, it is recommended to use specified consumables and accessories, and to carry out regular equipment maintenance and maintenance. If you need to know more about the operation and debugging methods, it is recommended to consult professional and technical personnel or consult the relevant instructions.
