Automatic thread dispensing machine is a machine used to apply sealing glue to fasteners such as screw threads and joint threads, also known as screw dispensing machine and screw sealant dispensing machine. It can take a circular path and is specially used for dispensing screws, bolts, and various joint products, and dispensing ink, and paint.
At present, the automatic thread dispensing machine manufacturers have Hongdahui Technology. Founded in 2013, Hongdahui Technology is a high-tech enterprise that provides precision dispensing, coating, gluing, industrial dispensing equipment, and auxiliary material assembly equipment in the industry.
The working principle of the automatic thread dispensing machine is to realize the dispensing operation of screws by controlling the flow of glue and the dispensing position. Specifically, it mainly extrudes the glue from the hose by rotating the threaded shaft, and then moves the nozzle by pneumatic or electric drive to achieve gluing or dispensing of the product.
Among them, the threaded shaft is a spiral shape that pulls the glue out of the hose and then conveys the glue to the nozzle. The nozzle moves to the surface of the product through pneumatic or electric control to achieve gluing or dispensing of the product. In order to achieve different gluing or dispensing shapes, the nozzle can be changed according to the shape and needs of the product.
In addition, fully automatic screw dispensers are usually equipped with a glue control system that can adjust the flow and pressure of the glue. By controlling the flow of glue, the screw dispenser can achieve precise control of the glue, so that the glue is evenly coated on the screw. At the same time, the screw dispenser also needs to accurately control the dispensing position, and is usually equipped with a motion control system that can control the movement trajectory of the dispenser so that it can accurately locate the screw position that needs to be dispensed.
In addition to the flow of glue and the control of the dispensing position, the screw dispenser also needs to ensure the accuracy and stability of the dispensing operation. To achieve this, screw dispensers are often equipped with sensors and monitoring systems that can monitor the flow and pressure of the glue, as well as the accuracy of the dispensing position. Through timely feedback and adjustment, the screw dispenser can ensure the quality and stability of the dispensing operation.
In general, the working principle of the thread dispensing machine is to achieve accurate dispensing of screws by controlling the flow of glue, accurately controlling the dispensing position, and ensuring the accuracy and stability of the dispensing operation.
Automatic thread dispensing machines are widely used in electronic components, auto parts, instrumentation and other industries. In addition, it is widely used in electronics, automotive, medical, aerospace, manufacturing, and other industries. Due to its convenient, fast, efficient and environmentally friendly characteristics, it has been welcomed and chosen by the majority of enterprises and users.
The advantages of the automatic thread dispensing machine mainly include:
1.High efficiency: The thread dispenser can complete the dispensing operation quickly and accurately, improving production efficiency.
2.High precision: The thread dispensing machine can accurately control the flow rate and dispensing position of the glue, which ensures the accuracy and uniformity of the glue.
3.Wide range of application: The thread dispensing machine is suitable for gluing all kinds of threads, screws, joints and other fasteners.
4.Simple operation: The operation of the thread dispensing machine is simple and easy to understand, convenient and fast, which reduces the labor intensity of workers.
5.Environmental protection and energy saving: The thread dispenser is electrically driven, which is more environmentally friendly and energy-saving than the traditional manual gluing method.
6.Easy maintenance: The maintenance of the thread dispenser is simple and easy, and the service life is long, which reduces the maintenance cost of the enterprise.
To sum up, the thread dispensing machine has the advantages of high efficiency, high precision, wide range of application, simple operation, environmental protection, energy saving and convenient maintenance, so it has been widely used in manufacturing, electronic components, auto parts, instrumentation and other industries.
The operation steps of the automatic thread dispenser are as follows:
1.Maintain the levelness of the precision dispensing machine platform, and the level of the platform is quite half debugged, which is the premise of debugging. Playing well horizontally will avoid a series of dispensing problems such as point deviation, more glue and less glue, and overflow.
2.Dispensing tips need to be selected based on the size of the product. The inner diameter of the needle is about half of the diameter of the dispensing dot, and choosing the right needle can ensure the quality of the dot and improve the production efficiency.
3.The setting of the dispensing time when the dispenser is programmed. The amount of dispensing machine should be half of the product spacing, so as to ensure that there is enough glue to paste the components and avoid excessive glue seepage. The amount of glue output of the high-precision automatic dispensing machine can be controlled by adjusting the glue time, and the dispensing time can also be set according to the environmental conditions (that is, the temperature of the workshop, the viscosity of the glue, the speed of dispensing, etc.), if the glue is easy to produce stringing, it is necessary to set the glue shutdown time and stop time in advance.
4.Adjustment of the air pressure of the dispenser controller. The pressure of the dispenser determines the amount of glue dispensed, which affects the speed and effect of dispensing. The pressure is high, and it is easy to have the problem of glue spraying and excessive glue volume, which affects the aesthetics of dispensing productsIf the pressure is too small, there will be problems such as uneven dispensing and non-glue, which will directly affect the product quality. Therefore, in the actual production, it is necessary to set the pressure according to the viscosity of the glue, the environment of the production workshop, and the temperature, and the temperature is too low, which will increase the viscosity of the glue and the fluidity will deteriorate, and the pressure value needs to be increased.
The above are the general steps to operate and debug the thread dispenser, the specific operation may vary depending on the equipment model and production environment, it is recommended to follow the equipment manual or consult professional and technical personnel to operate.
The selection principle of automatic thread dispensing machine can refer to the following points:
1.Selection according to the nature of glue: Different glues have different properties, including viscosity, curing time, use environment, etc., and it is necessary to choose the right dispensing machine according to the use scenario.
2.According to the dispensing process: different dispensing processes require different dispensing machines, such as precision dispensing, AB glue filling, etc., and different types of dispensing machines need to be selected.
3.Selection according to work efficiency and environment: Different working environments and production efficiency need to choose different dispensing machines, such as manual glue guns are suitable for scenarios with few products and no pursuit of efficiency, and automatic dispensers are suitable for high-efficiency and high-volume production scenarios.
4.According to the cost selection: different dispensing solutions have different costs, and it is necessary to consider the balance of cost and benefit to choose the appropriate dispensing machine and solution.
5.According to the brand and service selection: choose a well-known brand and a good service dispensing machine supplier, you can get better product quality and after-sales service.
To sum up, the selection of thread dispensing machine needs to comprehensively consider factors such as glue properties, dispensing process, work efficiency and environment, cost, brand and service, etc., and select the appropriate dispensing machine type and model according to actual needs.
