Description

Technical Field

[0001] This utility model relates to the field of glue dispensing machine cleaning technology, and in particular to an automatic cleaning device for glue dispensing machines. Background Technology

[0002] A dispensing machine is an industrial device specifically designed for the automated or semi-automated precise coating, dispensing, sealing, or bonding of fluid materials such as adhesives, resins, and silicone. Through a sophisticated fluid control system and motion actuators, it achieves the metering, proportioning, mixing, and precise application of fluid materials. It is widely used in industries such as electronics, automobile manufacturing, medical devices, and new energy, and can significantly improve production efficiency, ensure consistent dispensing, reduce material waste, and meet the process requirements of sealing, insulation, fixing, and waterproofing of products.

[0003] Automatic cleaning equipment for dispensing machines is a specialized piece of equipment designed to provide automated cleaning services for dispensing machines during production breaks or after operations. It integrates a cleaning fluid supply system, rinsing mechanism, pipeline circulation device, and waste liquid recovery and treatment module. Triggered by preset programs or sensors, the equipment is widely used in production scenarios in electronics, automotive, and new energy industries that rely on dispensing processes. It prevents residual materials from solidifying and clogging the equipment, ensures the accuracy of subsequent dispensing, reduces the tediousness and errors of manual cleaning, and improves the continuity of the production line and the service life of the equipment. During operation, the dispensing machine's glue circuit system includes precision valves, slender pipelines, and a mixing chamber. For some complex structures, the cleaning fluid in automatic cleaning equipment may not be able to completely cover all dead corners. If residual glue is not removed, long-term accumulation will lead to pipeline blockage, decreased glue dosage accuracy, and even affect the purity of the next batch of glue. How to solve this problem? In the existing technology, guide holes or spray holes are added inside the mixing chamber and valve chamber to guide the cleaning fluid to the dead corner area. However, when cleaning the dispensing needle, glue will remain on the inner wall and outlet after being sprayed out of the needle, especially for fast-drying glue, silicone and other easily curing glues. If not cleaned in time, it will cause the needle to be blocked, affecting the smoothness and accuracy of the next dispensing. Summary of the Invention

[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an automatic cleaning device for a dispensing machine, comprising a body 1, model PGV501. The working principle involves first storing adhesives A and B separately in material tanks equipped with vacuum feeding and stirring functions to ensure good adhesive storage conditions.

A motor 202 (model 57BYG250C) is mounted on the top of the tank 201. Its working principle is essentially a step-by-step rotational energy conversion process. The stator winding's on / off sequence is controlled by pulse signals output from the controller, and the rotor is driven to rotate at a fixed step angle using electromagnetic force, thereby achieving high-precision position and speed control. A rotating shaft 203 is fixedly connected to the output end of the motor 202, and the kinetic energy of the motor 202 drives the rotating shaft 203. 3.

The front side of the bearing plate 5 is fixedly connected to the rear side of the motor 202. The bearing plate 5 is used to support the motor 202.

[0032] Specifically, starting the motor 202 drives the rotating shaft 203 to rotate. The first bevel gear 204 on the rotating shaft 203 rotates accordingly, driving the second bevel gear 207 meshing with it to rotate. This causes the rotating rod 206 to rotate in the middle of the fixed plate 205. The third bevel gear 208 on the rotating rod 206 rotates synchronously, driving the fourth bevel gear 210 meshing with it to rotate. This causes the threaded rod 211 to rotate at the bottom of the connecting plate 209. The threaded block 212 on the threaded rod 211 moves accordingly.

The blowing assembly 305 includes an L-shaped plate 3051, which is fixedly connected to the right side of the top of the threaded block 212. A fan 3052 is provided on the right side of the L-shaped plate 3051. A rotating block 6 is provided at the top of the machine body 1. The top of the rotating block 6 is rotatably connected to the bottom of the threaded rod 211. A limit rod 7 is fixedly connected to the left side of the rotating block 6. The outer side of the limit rod 7 is slidably connected to the left side of the threaded block 212 to limit the movement.

[0034] Specifically, the motor 202 drives the rotating shaft 203 and the crossbar 301 to rotate, which in turn causes the two stirring rods 302 on the crossbar 301 to rotate, stirring the cleaning solution in the tank 201 and promoting uniform mixing. The cleaning solution flows into the storage box 214 through the connecting hose 303 for cleaning the dispensing needle. After the dispensing needle is cleaned, since the threaded block 212 is equipped with an L-shaped plate 3051 and a fan 3052, the fan 3052 is turned on, and the airflow generated by the fan blows on the dispensing needle to dry it. The top of the machine body 1 is equipped with a rotating block 6, and the top of the rotating block 6 is rotatably connected to the bottom of the threaded rod 211. The left side of the rotating block 6 is fixedly connected to a limiting rod 7, and the outer side of the limiting rod 7 is slidably connected to the left side of the threaded block 212 to achieve limiting.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Hinges 8 are fixedly connected to the upper and lower ends of the front side of the body 1. Cabinet doors 9 are fixedly connected to the outside of the hinges 8. The hinges 8 can open the cabinet doors 9 better. A mounting plate 10 is provided on the rear side of the body 1. Multiple sliding grooves 11 are equally spaced in the middle of the mounting plate 10 to play the role of ventilation and heat dissipation.

[0036] Specifically, the upper and lower ends of the front side of the body 1 are fixedly connected to the hinge 8, and the outer side of the hinge 8 is fixedly connected to the cabinet door 9. The hinge 8 allows the cabinet door 9 to be opened conveniently. The rear side of the body 1 is provided with a mounting plate 10, and multiple sliding grooves 11 are equally spaced in the middle of the mounting plate 10 for ventilation and heat dissipation.

[0037] Working principle: The motor 202 is started, which drives the rotating shaft 203 to rotate. The first bevel gear 204 on the rotating shaft 203 rotates accordingly, driving the meshing second bevel gear 207 to rotate. This causes the rotating rod 206 to rotate in the middle of the fixed plate 205. The third bevel gear 208 on the rotating rod 206 also rotates synchronously, driving the meshing fourth bevel gear 210 to rotate. This causes the threaded rod 211 to rotate at the bottom of the connecting plate 209. The threaded block 212 on the threaded rod 211 moves accordingly. The operator can pull the telescopic rod 213 to adjust the position of the liquid storage box 214, so that the dispensing needle can be placed in the liquid storage box 214. By moving the liquid storage box 214 up and down slightly, the cleaning effect is better.

[0038] The motor 202 drives the rotating shaft 203 and the crossbar 301 to rotate, which in turn causes the two stirring rods 302 on the crossbar 301 to rotate, stirring the cleaning liquid in the tank 201 and making the cleaning liquid evenly mixed. The cleaning liquid enters the storage box 214 through the connecting hose 303 for cleaning the dispensing needle. After the dispensing needle is cleaned, an L-shaped plate 3051 is installed on the threaded block 212, and a fan 3052 is installed on the L-shaped plate 3051. The fan 3052 is turned on, generating airflow to blow the dispensing needle and dry it.
