[0028] The reciprocating ejector assembly includes a second screw rod 19 that rotates and is inserted between two sets of guide blocks 18. A second motor 21 is provided at one end of the second screw rod 19. The second motor 21 is connected to one side of the guide block 18. The second screw rod 19 is externally threadedly connected to a guide seat 20. The upper end of the guide seat 20 slides inside the fixed platform 16. A third electric mechanism 28 is fixedly provided on the inner surface of the guide seat 20. A top contact piece is provided at the telescopic end of the third electric mechanism 28.

This technical structure is a prior art known in the art and will not be elaborated on here.

[0030] The feeding assembly includes a delivery pipe 39 connected and installed at the rear end of the glue storage tank 4. The end of the delivery pipe 39 away from the glue storage tank 4 is connected and installed with a glue feeding barrel 37. The top of the glue feeding barrel 37 is provided with an exhaust valve. The glue feeding barrel 37 is fixedly connected to the glue dispensing station 1. The inside of the glue feeding barrel 37 is sealed and slidably connected with a piston plate 42. A piston cylinder 38 is provided on one side of the piston plate 42. The piston cylinder 38 is arranged on the outer side of the end of the glue feeding barrel 37 away from the end of the delivery pipe 39. A driving motor 40 is provided on the outer side of one end of the glue feeding barrel 37 away from the piston cylinder 38. The output end of the driving motor 40 extends to the inside of the glue feeding barrel 37 and is provided with a stirring blade 43 on the outside. Baffles are respectively installed on both sides of the inner wall of the glue feeding barrel 37 and near the stirring blade 43. The upper part of the glue feeding barrel 37 is connected to the hose 9 through a reflux pipe 41 installed in communication. A valve is provided on the outer side of the top of the delivery pipe 39. The outer side of the delivery pipe 39 below the valve is connected and installed with a first air pressure control valve, and a second air pressure control valve is provided on the outer side of the reflux pipe 41 and near the hose 9.

[0031] Reference Manual Attached Figure 7 and Figure 8 It can be seen that when glue is to be injected into the glue storage tank 4, the control valve, the first air pressure valve and the second air pressure valve at the hose 9 are closed, and the valve at the delivery pipe 39 is opened. Then, the piston cylinder 38 drives the piston plate 42 to move to one end inside the glue feeding barrel 37, and at the same time, the hydraulic component inside the glue storage tank 4 is withdrawn, so that the glue liquid can be pushed to the delivery pipe 39, and then the glue liquid can be stored in the glue storage tank 4 for use. Driven by the rotation of the driving motor 40, the glue liquid can be mixed, so that the various glue liquids can be fully integrated during the glue injection, thereby improving the quality of the glue liquid; The baffles on both sides of the stirring blade 43 can prevent the piston plate 42 from making hard contact with the stirring blade 43 when the piston plate 42 is pushed toward one end of the stirring blade 43 .

[0032] When the glue injection of the hose 9 is completed, in order to avoid excess glue liquid inside the hose 9 and the delivery pipe 39, the piston plate 42 can be driven to move in the reverse direction by the piston cylinder 38. At the same time, the control valve at the hose 9 and the valve at the delivery pipe 39 are closed, and the first air pressure valve and the second air pressure valve are opened. Under the negative pressure state inside the glue feeding barrel 37, the circulation pipeline is sucked to avoid the glue inside the circulation pipeline from solidifying and affecting the subsequent use. After the operation is completed, all valves are closed.

[0033] When it is necessary to inject glue into the glue storage tank 4 again, since there is air in the delivery pipe 39, the second air pressure valve is opened, and the piston plate 42 is pushed to move into the delivery pipe 39 to squeeze the glue liquid until the air is exhausted. Then the second air pressure valve is closed, and the valve at the delivery pipe 39 is opened. The hydraulic components inside the glue storage tank 4 cooperate to withdraw to complete the glue injection work.

[0034] Working principle: When the device is in use, the parts of the car door lock are placed on the upper surface of the workpiece plate, and the first motor 11 and the first screw rod 8 are driven to make the slide 10 translate on the outer surface of the guide rail platform 7, and then the glue dispensing component 12 dispenses glue on its parts. If the needle is blocked during the glue dispensing process, which affects the glue dispensing operation, the second electric mechanism 25 is extended to make the fixed platform 16 approach one end of the glue dispensing component 12, and the moving block 36 is driven to move by starting the multi-stage push cylinder 44, until the second positioner 34 above the moving block 36 corresponds to the position of the infrared alarm sensor 23 at the connecting seat 24. After the infrared alarm sensor 23 buzzes, the position of the slide 35 can be positioned at the lower end of the glue dispensing component 12, and the second motor 21 drives the second screw rod 19 to rotate, so that the outer guide seat 20 and the guide rod 27 also move to the position of the slide 35, until the first positioner 30 at the upper end of the guide rod 27 corresponds to the position of the infrared alarm sensor 23, and the third electric mechanism 28 pushes the guide rod 27 upward to promote The top seat 29 is brought into contact with the rubber sleeve 31, and the internal slide 35 is lifted up. Then, after removing the blocked needle, a new dispensing needle 32 is lifted up to the dispensing end of the dispensing component 12. When the glue is to be injected into the glue storage tank 4, the control valve, the first air pressure valve and the second air pressure valve at the hose 9 are closed, and the valve at the delivery pipe 39 is opened. Then, the piston cylinder 38 drives the piston plate 42 to move to one end inside the glue feed barrel 37, and at the same time, the hydraulic component inside the glue storage tank 4 is withdrawn, so that the glue liquid can be pushed to the delivery pipe 3 9, so that it is convenient to store the glue liquid into the glue storage tank 4 for use. After the glue injection of the hose 9 is completed, in order to avoid excess glue liquid in the hose 9 and the delivery pipe 39, the piston plate 42 can be driven to move in the opposite direction by the piston cylinder 38. At the same time, the control valve at the hose 9 and the valve at the delivery pipe 39 are closed, and the first air pressure valve and the second air pressure valve are opened. Under the negative pressure state inside the glue feeding barrel 37, the circulation pipeline is sucked to avoid the glue inside the circulation pipeline from solidifying and affecting the subsequent use. After the operation is completed, all valves are closed.
