[0032] The piston chamber 10 is arranged in the pump body shell 1, the piston 22 is arranged in the piston chamber 10, the piston 22 can reciprocate along the piston chamber 10, the compression spring 21 is arranged at the top of the piston chamber 10, and the bottom of the compression spring 21 is connected with the piston 22 through the piston shaft 23 to apply the elastic force to the piston 22, the side wall of the pump body shell 1 is provided with the air inlet hole 100, the air inlet hole 100 is located below the piston chamber 10, the air inlet joint 101 is connected to the air inlet hole 100, and the air inlet joint 101 is used to supply compressed air to the piston chamber 10, when the compressed air enters the piston chamber 10 from the air inlet hole 100, the piston 22 is subjected to the upward thrust, and then the piston 22 moves upward to overcome the pressure of the spring, when the air pressure decreases or stops, the elastic force of the compression spring 21 resets the piston 22 automatically, and the piston 22 is pushed downward to realize the reciprocating movement of the piston 22, it should be noted that the thrust of the piston 22 can be changed by adjusting the compression force of the compression spring 21, and then the glue applying amount and speed can be flexibly adjusted.

[0033] The nozzle seat 4 is connected with the bottom of the pump body shell 1, the sealing connector 5 is arranged between the nozzle seat 4 and the pump body shell 1, the glue applying nozzle 6 is arranged at the bottom of the nozzle seat 4, the nozzle seat 4 has a glue injection channel 40 inside, the glue inlet connector 3 is arranged on the side wall of the nozzle seat 4 and communicates with the glue injection channel 40, the glue applying nozzle 6 has a glue outlet 60 inside, the glue outlet 60 communicates with the glue injection channel 40, the glue applying push rod 24 is connected with the piston shaft 23 at the top, and the bottom of the glue applying push rod 24 penetrates through the sealing connector 5 and partially extends into the glue injection channel 40. When the piston 22 moves upwards, the glue injection channel 40 can generate negative pressure and suck the glue in the glue inlet connector 3 into the glue injection channel 40; when the piston 22 is pushed downwards by the elastic force of the compression spring 21, the glue in the glue injection channel 40 can be pushed into the glue outlet 60 through the glue applying push rod 24, so that the glue sealing operation on the battery is realized; the sealing connector 5 can prevent the glue from leaking from the gap between the nozzle seat 4 and the pump body shell 1, so that the glue can only flow out through the glue applying nozzle 6, and the equipment pollution and glue waste are avoided.

[0034] Further, the top and bottom of the sealing connector 5 are respectively provided with first O-rings 51, and the inner wall of the first O-rings 51 abuts against the outer side wall of the glue applying push rod 24. The glue applying push rod 24 moves up and down through the sealing connector 5 during work, and the first O-rings 51 arranged at the top and bottom of the sealing connector 5 can make the glue applying push rod 24 closely contact with the inner wall of the sealing connector 5, so that the glue can be prevented from leaking from the gap between the glue applying push rod 24 and the sealing connector 5.

In this way, when the glue applying push rod 24 pushes the glue, the glue applying flow can be controlled by the tapered structure to prevent a large amount of glue from gushing out at one time, thereby improving the glue applying and sealing effect of the battery.

[0038] Further, the bottom of the glue applying nozzle 6 is provided with an external threaded column 61, the bottom of the nozzle seat 4 is provided with an internal threaded hole 42, and the external threaded column 61 is connected with the internal threaded hole 42 through a threaded connection. In this way, when it is necessary to clean, maintain or replace the glue applying nozzle 6, the operator can quickly disassemble, thereby improving the maintenance efficiency.

[0039] The bottom of the external threaded column 61 is sleeved with a third O-ring 62. The third O-ring 62 arranged at the bottom of the external threaded column 61 can fill the gap of the threaded connection, thereby further enhancing the sealing effect and preventing the glue from leaking from the threaded connection part.

[0040] Further, the glue applying nozzle 6 is internally provided with a nozzle lining 63, the nozzle lining 63 is provided with a hole 630 for the extension and retraction of the glue applying push rod 24, and the glue injection channel 40 is communicated with the glue outlet 60 through the hole 630. The nozzle lining 63 serves as an independent component, which is convenient for maintenance and replacement. The nozzle lining 63 arranged inside the glue applying nozzle 6 can avoid direct friction between the glue applying push rod 24 and the glue applying nozzle 6. When the nozzle lining 63 is damaged or worn, it can be quickly replaced without replacing the entire nozzle, thereby reducing the maintenance cost.

[0041] Further, the adjustment screw 7 is also included, the threaded part of the adjustment screw 7 is connected with the top of the pump body shell 1 through a threaded connection, and the bottom of the adjustment screw 7 is provided with a positioning groove 71 for positioning and abutting against the compression spring 21. The adjustment screw 7 is connected with the top of the pump body shell 1 through a threaded connection, and the user can rotate the adjustment screw 7 to adjust its position, thereby adjusting the pre-compression amount of the compression spring 21 to control the force applied by the compression spring 21 on the piston 22.

[0042] Further, the adjustment screw 7 is sleeved with a fourth O-ring 72, and the arrangement of the fourth O-ring 72 can improve the sealing between the piston chamber 10 and the external environment, prevent the internal pressure from being lost, and ensure the normal operation of the glue applying system.
