Description

Technical Field

[0001] The utility model relates to the technical field of cleaning needles of glue dispensing machines, in particular to a device for automatically cleaning the needles of glue dispensing machines. Background Art

[0002] Glue dispensing in optical devices involves applying a certain amount of glue to the surface or joints of optoelectronic components to reinforce and protect them. Compared to traditional fastening methods, component dispensing offers a more flexible solution that is better suited to modern electronic product manufacturing. After dispensing is completed or after a period of dispensing interruption, residual glue is likely to remain on the dispensing needle. This residual glue can affect the accuracy and quality of the next dispensing operation, so it is necessary to remove any residual glue from the dispensing needle before the next dispensing operation.

[0003] In existing technologies, residual glue is typically removed by the operator wiping the dispensing needle with a soft cloth or cotton swab. While this method is simple to operate, its effectiveness is significantly affected by the operator's skill level. Furthermore, this cleaning method is difficult to adapt to high-speed production lines, reducing production efficiency. Therefore, a device is needed to automatically clean the dispensing needle to prevent needle bending and deformation due to operator error, or needle clogging due to missed wipes, while also being adaptable to high-speed production lines. Utility Model Content

[0004] The present invention aims to provide a device for automatically cleaning the needle of a glue dispenser, in order to solve the problem raised in the above-mentioned background art. In the existing technology, residual glue is generally removed by the operator wiping the glue dispenser needle with a soft cloth or cotton swab. Although this method is simple to operate, the cleaning effect is greatly affected by the operator's skill level. In addition, this cleaning method is difficult to adapt to high-speed production lines, which will reduce production efficiency.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a device for automatically cleaning the needle of a dispensing machine, comprising:

[0007] A main body assembly, the main body assembly comprising a mounting plate and a support plate;

[0008] The support plate is fixed on the upper surface of the mounting plate;

[0009] an anti-blocking assembly, the anti-blocking assembly comprising a second fixed plate, a steering motor, a second rotating shaft, a cleaning roller, and a bearing;

[0010] There are two second fixed plates, which are fixed on the two ends of the upper surface of the mounting plate respectively. The steering motor is fixed on the side of one of the second fixed plates, and the bearing is fixed inside the other second fixed plate. One end of the second rotating shaft is fixed to the output end of the steering motor, and the other end is inserted into the bearing. The cleaning roller is sleeved in the middle of the second rotating shaft.

[0011] Furthermore, the steering motor, the second rotating shaft and its corresponding related components are each in two groups, which are symmetrically distributed on the second fixed plate.

[0012] Furthermore, the second rotating shaft passes through and is rotatably connected to the lower section of the support plate.

[0013] Furthermore, the main body assembly further includes a first fixing plate and a guide rail;

[0014] There are two first fixing plates, which are fixed on the upper portion of the support plate, and the guide rail is fixed between the two first fixing plates.

[0015] Furthermore, the main body assembly further includes a movable hole, a time relay, a servo motor and a first rotating shaft;

[0016] The movable hole is opened in the middle of the support plate, the time relay is sleeved on the guide rail, the servo motor is fixed on the upper end of the time relay and sleeved on the guide rail, the first rotating shaft is fixed on the output end of the servo motor, and the first rotating shaft is inserted into the movable hole.

[0017] Furthermore, the main body assembly also includes a fixing frame, a vacuum pump, a syringe and a needle;

[0018] The fixing frame is fixed on the side of the first rotating shaft, the vacuum pump is fixed on the fixing frame, the syringe is fixed on the fixing frame and connected to the vacuum pump through a catheter, and the needle is screwed on the syringe.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] The utility model, through the anti-blocking component, sets the descending time of the time relay and the descending direction position cycle on the main machine, and then sets the dispensing time of the vacuum pump. In this way, the dispensing needle can smoothly dispense glue on the product that needs to be dispensed each time. After the fixed dispensing cycle, the needle will descend and rotate to the specified direction according to the cycle set by the time relay, and fit with the cleaning roller. At this time, the steering motor fixed on the second fixed plate is started, driving the second rotating shaft to rotate in the bearing, driving the cleaning roller to rotate, and cleaning the residual glue on the needle. This setting can avoid needle blockage and free the operator's hands. The needle will not be bent or deformed due to excessive force of the operator. On the other hand, the needle will not be blocked due to no one wiping the needle for a long time. Finally, the automated production process can be realized to ensure production continuity.
