Description

Technical Field

[0001] The utility model belongs to an auxiliary device of a heat-sealing process equipment for producing a new energy battery core soft package, and specifically relates to a failed heat-sealing cleaning and recovery device for the heat-sealing process equipment for producing a new energy battery core, which is used for cleaning a failed heat-sealing head. Background Art

[0002] At present, in the production and trial production of new energy battery soft packs, 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, which will melt when the heat seal head is heated to above 190°C, thus contaminating the copper heat seal head. The increased contamination seriously affects the heat conductivity of the heat seal head, and then affects the heat seal stability and uniformity, which has a great impact on battery safety and performance, so it needs to be cleaned regularly to prevent failure. However, when cleaning the heat seal head, it needs to be heated to 190°C and then wiped manually, which is very easy to burn. At the same time, the special solvent NMP needs to be used in the cleaning process, which is very volatile at high temperatures and harmful to the human body. Summary of the invention

[0003] In order to solve the above-mentioned problems existing in the prior art, the utility model provides a failed heat seal cleaning and recovery device for heat sealing process equipment in the production of new energy batteries.

[0032] In this embodiment, the upper reverse speed gear 1, the upper forward speed gear 2, the lower reverse speed gear 3 and the lower forward speed gear 5 are respectively connected to the cleaning roller brush 16 through the roller brush coupling 18, driving the roller brush to rotate rapidly, thereby achieving cleaning and functional recovery of the heat sealing head of the heat sealing process equipment.

[0033] In this embodiment, the outer shell includes a front baffle 8, a rear baffle 15 and two symmetrically arranged outer cover shells 12; the front baffle 8, the rear baffle 15 and the two symmetrically arranged outer cover shells 12 are enclosed and fixed by bolts; the motor 7 is fixed on the front baffle 8; the upper reverse gear 1, the upper forward gear 2, the lower reverse gear 3 and the lower forward gear 5 of the two-way gear set transmission mechanism are respectively rotatably connected to the front baffle 8 through the gear shaft; the cleaning roller brush 16 is respectively rotatably connected to the rear baffle 15 through the roller brush shaft; the piston head of the multi-stage cylinder 14 is fixedly connected to the rear baffle 15; a gap is left between the two outer cover shells 12 to form two symmetrical axial through grooves, and the heat sealing head extends into the inner cavity of the outer shell through the axial through groove for cleaning.

[0034] In this embodiment, it also includes an intermediate plate 9, which is arranged in the inner cavity of the outer shell and is connected to the front baffle 8 and the rear baffle 15 through four supporting rollers 10; the inner cavity of the outer shell is divided into two structural cavities by the intermediate plate 9, one structural cavity is installed with a gear transmission structure through a mounting hole, and the other structural cavity is installed with a cleaning roller brush through a mounting hole.

[0035] Specifically, in this embodiment, four threaded holes are opened at the four corners of the front baffle 8, the middle plate 9, and the rear baffle 15, and the front baffle 8, the middle plate 9, and the rear baffle 15 are connected by four support rollers 10 and screwed together with the threads. T-shaped guide holes are opened at the upper and lower ends of the front baffle 8, the middle plate 9, and the rear baffle 15, and the T-shaped guide holes are connected with the axial through grooves on the outer shell. The T-shaped guide holes are used to be combined with the upper and lower T-shaped heat sealing heads as guide rails, so that when cleaning starts, the cleaning roller brush can move back and forth along the direction of the heat sealing head to complete cleaning.

[0036] The two outer cover shells 12 are engaged with the front and rear baffles through the upper and lower bolt holes and the middle bolt hole to form a semi-enclosed cavity, and an exhaust hole is opened on the side of the outer cover shell 12 near the roller brush end, and an exhaust fan is connected to form a slight negative pressure inside to discharge the vaporized harmful solvent gas to avoid harm to personnel.

[0037] Two threaded holes are respectively opened in the middle of the roller brush of the outer cover shell 12, and two solvent spray heads 17 are screwed and installed. The two solvent spray heads 17 are connected to the liquid supply pump, and the solvent can be evenly sprayed when the roller brush rotates at a high speed to wet the roller brush.

[0038] In this embodiment, the piston head of the multi-stage cylinder 14 is connected to the rear baffle 15 of the outer shell through the connecting plate 13. The rear end of the multi-stage cylinder has a flange structure, and the flange is connected to the heat sealing process equipment frame through four through holes.

[0039] Specifically, in this embodiment, the connecting plate 13 has a threaded column in the middle, which can be screwed together with the piston head of the multi-stage cylinder 14, and has through holes on both sides, which can be screwed together with the bolt holes on both sides of the rear baffle 15. When the multi-stage cylinder 14 is extended and retracted, the entire cleaning unit can be driven to move repeatedly along the heat sealing head, so even if the cleaning unit is relatively small, the cleaning of the entire heat sealing head can still be completed.

[0040] The working principle of this embodiment is:

[0041] During the rotation of the double-layer gear 4, the driven gear presents two rotation directions due to different transmission modes, so that the roller brush cleaning the heat sealing head on the same side rotates in different directions, thereby cleaning the top and side surfaces of the heat sealing head and scraping off the strong adhesive PE glue. While rotating at high speed for cleaning, the multi-stage cylinder can move slowly back and forth to complete the cleaning of the entire heat sealing head. The operating speed of the multi-stage cylinder can be adjusted by the pressure valve.

[0042] The following briefly describes the use process of this embodiment:

[0043] The failed heat seal cleaning and recovery device for heat seal process equipment in the production of new energy batteries described in this embodiment, as an auxiliary equipment of the heat seal process equipment, does not need to be installed again after installation and can be directly driven and used.

[0044] Note during installation: 1. When installing the equipment, the T-shaped guide rail and the heat sealing head should be installed in the center; 2. The multi-stage cylinder should be fixed on the heat sealing equipment frame and fixed firmly, and the heat sealing work will not be affected when the cylinder shrinks.

[0045] When the heat seal fails, the temperature of the heat seal head remains unchanged and is maintained at 190°C. The cleaning recovery system is started, and the motor is started, driving the four cleaning rollers to rotate at high speed. At this time, the liquid supply pump starts to inject liquid, and the solvent is evenly sprayed on the cleaning roller brush through the solvent nozzle. The suction pump is turned on to create a micro-negative pressure environment. After the cleaning roller brush is moistened, the multi-stage cylinder extends and slowly drives the cleaning unit to clean along the heat seal head. When the stroke limit is reached, the multi-stage cylinder is retracted. During the retraction process, the cleaning unit is slowly driven along the heat seal head for cleaning again. After several cycles, it just returns to the initial position, the motor drive stops, the injection pump stops, and the suction pump stops. At this time, the processing of the upper and lower T-shaped heat seal heads of the heat sealing equipment has been completed.

[0046] For cleaning of the equipment, it is only necessary to remove the outer cover shell 12 and rinse and clean the roller brush, the inner side of the outer cover shell and other parts with clean water, which is very simple.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
