Description

Technical Field

[0001] The utility model relates to the technical field of battery cell production equipment, and more specifically, to a failure prevention safety disposal system for heat sealing process equipment in the production of new energy battery cells. Background Art

[0002] Currently, in the production and trial production of new energy battery cells, the aluminum-plastic film heat sealing process is an indispensable link. Because there is PE film or glue on the surface of the aluminum-plastic film, it will melt when the heat seal head is heated to above 190°C, thus contaminating the copper heat seal head. The increased contamination will seriously affect the thermal conductivity of the heat seal head, and then affect the stability and uniformity of the heat seal, which has a great impact on battery safety and performance. Therefore, it needs to be cleaned regularly to prevent failure.

[0003] When cleaning the heat sealing head, it is also necessary to heat it to 190°C to melt the PE film or glue before cleaning. The current cleaning method can only be done by manual wiping, but it is very easy to get burned during the wiping process. At the same time, a special solvent NMP is required during the cleaning process, which is very volatile at high temperatures and harmful to the human body. Utility Model Content

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, but not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figures 1 to 6 The present embodiment provides a new energy battery cell production heat sealing process equipment failure prevention safety disposal system, including: a safety shell 100, a fixed magnetic base 200, a liquid injection cavity 300, a wiper head 400 and a driving mechanism 500.

[0039] The safety shell 100 has a rectangular shell body 130, and the shell body 130 has a accommodating space inside. The two ends of the shell body 130 are sealed by end plates 140. The end plates 140 are detachably connected to the shell body 130 by screws. The inner walls on both sides of the shell body 130 are provided with sliding grooves 160 along the length direction thereof.

[0040] The shell body 130 is provided with a liquid injection port 110 , and the bottom is provided with a rectangular notch 120 extending along the length direction thereof. The safety shell 100 is also provided with a suction port 150 , and the suction port 150 is connected to a suction pump.

[0041] The two side edges of the notch 120 are inclined toward the inside of the safety shell 100 to form a guide portion 121 .

[0042] The fixed magnetic base 200 is used to fix the safety shell 100 on the heat sealing process equipment. The fixed magnetic base 200 can control magnetic conduction and magnetic de-magnetization. When magnetic conduction occurs, it can be adsorbed on the iron beams and plates on both sides of the heat sealing process equipment. In this embodiment, there are two fixed magnetic bases 200, which are respectively connected to the end plates 140 on both sides of the shell body 130.

[0043] The injection chamber 300 has a hollow cavity and is constructed as a gate-shaped structure opening downward. Sliders 340 are provided on the outer walls of both sides of the injection chamber 300. The sliders 340 cooperate with the slide grooves 160 inside the shell body 130, and the injection chamber 300 is slidably connected to the inside of the shell body 130 along the length direction of the shell body 130.

[0044] The outer wall of the liquid injection cavity 300 is provided with a liquid inlet 310 , and the inner wall is provided with a liquid outlet 320 . The liquid inlet 310 is connected to the liquid injection port 110 through a flexible pipeline.

[0045] Two cleaning holes 330 are provided at the bottom of the injection cavity 300 , and detachable plugs are provided on the cleaning holes 330 .

[0046] The wiping head 400 is made of absorbent flexible material and is constructed in a gate-shaped structure with an opening facing downward. The wiping head 400 is closely connected to the inner wall of the injection cavity 300. The bottom opening width of the wiping head 400 is the same as the spacing between the guide parts 121 on both sides.

[0047] In order to make the wipe head 400 wet more evenly, in this embodiment, there are three liquid inlet holes 310, which are evenly distributed on the top surface of the liquid injection cavity 300 along the length direction of the liquid injection cavity 300, and the liquid outlet holes 320 are constructed as capillary pores distributed on the inner wall of the liquid injection cavity 300.

[0048] In order to facilitate the replacement of the wiping head 400, in this embodiment, the wiping head 400 is detachably connected to the inner wall of the injection cavity 300 through a porous back plate by screws. By replacing the wiping head 400 of different sizes, it can adapt to heat sealing heads of different thicknesses.

[0049] As a further solution, the wiping head 400 is composed of a top wiping head 410 and side wiping heads 420 on both sides. The top wiping head 410 and the side wiping head 420 are independently and detachably connected to the inner wall of the injection chamber 300, so that the top wiping head 410 and the side wiping head 420 can be replaced separately, which is more flexible to use. When the wiping head is partially damaged, part of the wiping head 400 can be replaced separately.

[0050] The driving mechanism 500 is disposed on the safety housing 100 , and can drive the injection cavity 300 to reciprocate in the length direction of the safety housing 100 .

[0051] In this embodiment, the driving mechanism 500 includes a driven bevel gear 510 , a reciprocating plate 520 , a driving bevel gear 530 and a driving motor 540 .

[0052] The driven bevel gear 510 is vertically arranged and is rotatably connected to a fixed shaft seat 550 arranged inside the safety shell 100 through a central shaft rod at its bottom. An eccentric shaft 511 is arranged on the top of the driven bevel gear 510; a movable hole 521 is arranged at one end of the reciprocating plate 520, and a central shaft 522 is arranged at the other end. The movable hole 521 is rotatably connected to the eccentric shaft 511, and the central shaft 522 is rotatably connected to the injection chamber 300; the active bevel gear 530 is horizontally arranged, connected to the rotating shaft of the driving motor 540, and meshed with the driven bevel gear 510. The driving motor 540 drives the driven bevel gear 510 to rotate through the active bevel gear 530. Under the action of the eccentric shaft 511 at the top of the driven bevel gear 510, the reciprocating plate 520 reciprocates, thereby driving the injection chamber 300 to reciprocate along the length direction inside the safety shell 100.

[0053] This implementation provides the working principle of the failure prevention safety disposal system for the heat sealing process equipment of new energy battery cell production:

[0054] First, align the notch 120 at the bottom of the safety shell 100 with the lower heat sealing head of the heat sealing process equipment and press it down. At this time, the top wiping head 410 and the side wiping head 420 are in full contact with the heat sealing head of the heat sealing equipment. Then, align the fixed magnetic seats 200 at both ends with the iron beams on both sides of the heat sealing process equipment and magnetize them to complete the equipment fixation.

[0055] Then, the injection hole 110 on the safety shell 100 is connected to the injection pump with a high temperature resistant conduit, and the suction hole 150 is connected to the suction pump through an air pipe. Turn on the injection pump, evenly add the cleaning solvent, turn on the suction pump, and create a slightly negative pressure environment in the safety shell 100. The cleaning solvent infiltrates the wipe head 400 through the injection cavity 300. After the wipe head 400 is fully moistened, the heat sealing process equipment is heated to 190°C, and the drive motor 540 is started to drive the wipe head 400 to reciprocate and start cleaning the lower heat sealing head.

[0056] The system can control the working time of the driving motor 540 and the injection time of the injection pump through the control system to achieve automatic control. After the driving motor 540 and the injection pump stop, the heat sealing process equipment is cooled down, the fixed magnetic base 200 is loosened, the entire device is rotated 180°, and the upper heat sealing head of the heat sealing process equipment is cleaned.

[0057] If the equipment is not used for a long time, it can be stored after cleaning. First, the end plates 140 at both ends of the shell body 130 are removed, and then the drive motor 540 and the fixed shaft seat 550 are removed in turn. At this time, the injection chamber 300 can be pulled out from the inside of the shell body 130 along the slide groove 160, and then the plug of the cleaning hole 330 at the bottom of the injection chamber 300 is unscrewed. If there is residual cleaning solvent, it can be poured out. Compressed air is pressed into one of the cleaning holes 330, and the solvent gas inside the injection chamber 300 can be completely discharged from the other cleaning hole 330, thereby achieving the purpose of thorough cleaning.
