Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery housing processing, and specifically relates to a processing device for power lithium battery housings. Background Art

[0002] The power lithium battery housing refers to the outer shell part used to encapsulate and protect the internal battery cells of the power lithium battery. Power lithium batteries are widely used in fields such as electric vehicles and energy storage systems. Its housing not only needs to play a physical protection role, but also needs to have certain strength, high temperature resistance, impact resistance, etc. The battery housing is usually made of materials such as metals (such as aluminum alloy, stainless steel) or plastics, and has functions such as isolating the external environment, improving safety, and preventing battery leakage.

[0003] When processing the power lithium battery housing, it is necessary to precisely weld each part of the battery housing (such as the upper cover, lower cover, and side wall) so that the battery housing can firmly protect the battery cells. Common welding methods include laser welding, spot welding, resistance welding, etc.

[0004] The Chinese patent discloses a processing device for power lithium battery housings (publication number CN213905433U). In this patented technology, by setting insertion rods and holes, when the pressing plate descends, it drives the insertion rods to descend and fit with the metal sheets at the lower end. As the insertion rods descend with the pressure generated when the pressing plate descends, they penetrate the metal sheets and insert into the holes on the upper surface of the mold, preventing the metal sheets from deforming, accelerating the speed of drilling the housing, and facilitating the installation of the housing screws.

[0005] However, when processing the existing power lithium battery housings, most use manual methods to clamp and position the housings, resulting in slow positioning efficiency and affecting the welding and processing operations of the lithium battery housings. Therefore, those skilled in the art have provided a processing device for power lithium battery housings to solve the problems raised in the above background art. Summary of the Invention

[0006] The purpose of the present invention is to provide a processing device for power lithium battery housings to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A processing device for power lithium battery housings includes a processing table. A placement plate is arranged on the upper surface of the processing table. A fixing groove is opened on the upper surface of the placement plate. A driving box is installed inside the fixing groove. A first screw rod and a second screw rod are respectively arranged through the driving box from front to back on one side of the placement plate. A motor is installed on one side of the placement plate. The driving end of the motor is connected to a rotating shaft. A second gear is arranged on the outside of the rotating shaft inside the driving box. A first positioning plate and a second positioning plate are respectively arranged from left to right on the upper surface of the placement plate;

[0009] A bracket is installed on the upper surface of the processing table behind the placement plate. A sliding plate is slidably installed on the upper surface of the bracket. A connecting plate is connected to the lower surface of the sliding plate. A fixing plate is installed below the connecting plate. A lifting plate is arranged below the fixing plate. A welding mechanism is installed on the lower surface of the lifting plate. An odor removal box is installed on the rear surface of the bracket. An air inlet pipe penetrates through the front surface of the odor removal box. A connecting pipe is arranged at the front end of the air inlet pipe. Suction heads are symmetrically arranged on the front surface of the connecting pipe. A first adsorption plate and a second adsorption plate are respectively arranged in the odor removal box from front to back. A filter is arranged behind the second adsorption plate inside the odor removal box. A smoking fan is arranged behind the filter inside the odor removal box.

[0010] As a further scheme of the present invention: A cylinder is installed on the rear surface of the bracket. The telescopic end of the cylinder is connected to the rear surface of the connecting plate. A guiding groove is formed on the upper surface of the bracket. The connecting plate is slidably arranged inside the guiding groove.

[0011] As a further scheme of the present invention: Two second electric lifting rods are symmetrically arranged on the upper surface of the fixing plate. The telescopic ends of the two second electric lifting rods are connected to the upper surface of the lifting plate.

[0012] As a further scheme of the present invention: Moving plates are arranged on the lower surfaces of the first positioning plate and the second positioning plate. The moving plates are slidably installed outside the first screw rod and the second screw rod.

[0013] As a further scheme of the present invention: External threads are arranged on the outside of the first screw rod and the second screw rod, and the external threads on the outside of the first screw rod are opposite to the external threads on the outside of the second screw rod in terms of thread direction.

[0014] As a further scheme of the present invention: Bearings are also symmetrically arranged inside the fixing groove. One end of the first screw rod and the second screw rod is embedded inside the bearing and connected to the bearing.

[0015] As a further scheme of the present invention: A first gear is arranged on the outside of the first screw rod inside the driving box. A third gear is arranged on the outside of the second screw rod inside the driving box. The second gear is meshed with the first gear and the third gear.

[0016] As a further scheme of the present invention: First electric lifting rods are symmetrically arranged on the lower surface of the bracket.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. When the motor of the present invention works, the second gear outside the rotating shaft will rotate. When it rotates, the first gear meshing with it will also rotate, and at the same time, the first screw rod and the second screw rod will rotate to move the first positioning plate and the second positioning plate. When moving, the distance between the first positioning plate and the second positioning plate can be adjusted, so that the power lithium battery case placed on the placing plate can be automatically clamped to ensure its stability, facilitating its welding process.

[0020] 2. When the smoking fan inside the odor removal box of the present invention works, the fumes generated by welding the power lithium battery case will enter the connecting pipe through the suction head, and finally enter the odor removal box through the air inlet pipe. The first adsorption plate and the second adsorption plate inside the odor removal box can be used to achieve double adsorption of the fumes, and then adsorbed again through the filter, thereby reducing the impact of the odor generated during the welding process on the staff. At the same time, the electric lifting rod can be used to lift the connecting pipe to adjust the position of the suction head, so as to efficiently suck the welding odor.

[0021] 3. When the cylinder of the present invention works, the connecting plate will move in the guiding groove in a guiding manner. When moving, the sliding plate can slide on the bracket, and when sliding, the position of the welding mechanism on the lower surface of the lifting plate can be adjusted, so as to weld the power lithium battery case. At the same time, the electric lifting rod can be used to lift the lifting rod, so as to adjust the height of the welding mechanism, enabling better welding of the power lithium battery case.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 6 , in the embodiment of the present invention, a power lithium battery case processing device includes a processing table 1.

A drive box 24 is installed inside the fixing groove. A first screw 25 and a second screw 27 are respectively arranged through the side of the drive box 24 from front to back. A motor 26 is installed on one side of the placing plate 2. The driving end of the motor 26 is connected with a rotating shaft 261. A second gear 262 is arranged outside the rotating shaft 261 inside the drive box 24. A first positioning plate 21 and a second positioning plate 22 are respectively arranged on the upper surface of the placing plate 2 from left to right;

[0031] A bracket 4 is installed on the upper surface of the processing table 1 behind the placing plate 2. A sliding plate 5 is slidably installed on the upper surface of the bracket 4. A connecting plate 51 is connected to the lower surface of the sliding plate 5. A fixing plate 52 is installed below the connecting plate 51. A lifting plate 53 is arranged below the fixing plate 52. A welding mechanism 7 is installed on the lower surface of the lifting plate 53. A deodorizing box 3 is installed on the rear surface of the bracket 4. An intake pipe 311 penetrates through the front surface of the deodorizing box 3. The front end of the intake pipe 311 is provided with a connecting pipe 31. Suction heads 312 are symmetrically arranged on the front surface of the connecting pipe 31. A first adsorption plate 331 and a second adsorption plate 341 are respectively arranged inside the deodorizing box 3 from front to back. A filter 35 is arranged behind the second adsorption plate 341 inside the deodorizing box 3. A smoking fan 36 is arranged behind the filter 35 inside the deodorizing box 3.

[0032] In Figure 1 and Figure 4 : A cylinder 6 is installed on the rear surface of the bracket 4. The telescopic end of the cylinder 6 is connected to the rear surface of the connecting plate 51. A guiding groove 41 is formed on the upper surface of the bracket 4. The connecting plate 51 is slidably arranged inside the guiding groove 41. Two second electric lifting rods 54 are symmetrically arranged on the upper surface of the fixing plate 52. The telescopic ends of the two second electric lifting rods 54 are connected to the upper surface of the lifting plate 53. This setting enables the lifting plate 53 to lift below the fixing plate 52 by using the two second electric lifting rods 54, so as to adjust the height of the welding mechanism 7. And the working of the cylinder 6 will cause the connecting plate 51 to move in a guiding manner inside the guiding groove 41, so as to adjust the position of the welding mechanism 7 on the lower surface of the lifting plate 53 to weld the power lithium battery case placed on the placing plate 2.

[0033] In Figure 2 and Figure 3 : Moving plates 23 are arranged on the lower surfaces of the first positioning plate 21 and the second positioning plate 22. The moving plates 23 are slidably installed outside the first screw rod 25 and the second screw rod 27. External threads are arranged on the outside of both the first screw rod 25 and the second screw rod 27, and the external threads on the outside of the first screw rod 25 are opposite to the external threads on the outside of the second screw rod 27. Bearings are also symmetrically arranged inside the fixed groove. One end of the first screw rod 25 and the second screw rod 27 is embedded inside the bearing and connected to the bearing. A first gear 251 is arranged on the outside of the first screw rod 25 inside the drive box 24. A third gear 271 is arranged on the outside of the second screw rod 27 inside the drive box 24. The second gear 262 is meshed with the first gear 251 and the third gear 271. This setting enables the second gear 262 on the outside of the rotating shaft 261 to rotate by the working of the motor 26, and when it rotates, the first gear 251 and the third gear 271 meshed with it will rotate, and at the same time, the first screw rod 25 and the second screw rod 27 will rotate to move the first positioning plate 21 and the second positioning plate 22. When moving, the distance between the first positioning plate 21 and the second positioning plate 22 can be adjusted, so as to automatically clamp the power lithium battery case placed on the placing plate 2 and ensure its stability for its welding process.

[0034] In Figure 5 and Figure 6In the middle: The lower surface of the support 4 is symmetrically provided with first electric lifting rods 32. A connecting sleeve 321 is sleeved outside the connecting pipe 31. The telescopic end of the first electric lifting rod 32 is connected to the upper surface of the connecting sleeve 321. Inside the deodorizing box 3, a first mounting plate 33 is arranged above the first adsorption plate 331, and a second mounting plate 34 is arranged below the second adsorption plate 341 inside the deodorizing box 3. This setting can make the flue gas play a baffle role when entering the inside of the deodorizing box 3 by using the first mounting plate 33 and the second mounting plate 34, and the flue gas generated by the welding of the power lithium battery shell can be adsorbed through the first adsorption plate 331 and the second adsorption plate 341, so as to protect the staff.

[0035] The working principle of the present invention is as follows: When the power lithium battery shell processing equipment of the present invention is in use, first, the two power lithium battery shells to be welded are placed on the placing plate 2. After placing, by starting the motor 26, the second gear 262 outside the rotating shaft 261 will rotate, and when it rotates, the first gear 251 and the third gear 271 meshed with it will rotate. At the same time, the first screw rod 25 and the second screw rod 27 will rotate to make the first positioning plate 21 and the second positioning plate 22 move. When moving, the distance between the first positioning plate 21 and the second positioning plate 22 can be adjusted, so that the power lithium battery shell placed on the placing plate 2 can be automatically clamped. After clamping, by starting the two second electric lifting rods 54, the lifting plate 53 can be lifted and lowered below the fixing plate 52, so that the height of the welding mechanism 7 can be adjusted. And by the operation of the cylinder 6, the connecting plate 51 can be guided to move inside the guiding groove 41, so that the position of the welding mechanism 7 on the lower surface of the lifting plate 53 can be adjusted to weld the power lithium battery shell placed on the placing plate 2. During the welding process, by starting the first electric lifting rod 32 to work, the connecting pipe 31 can be lifted and lowered, and the height of the connecting pipe 31 can be adjusted when lifting and lowering. After adjustment, by starting the smoking fan 36 inside the deodorizing box 3, the flue gas generated by the welding of the power lithium battery shell can enter the connecting pipe 31 through the suction head 312, and finally enter the deodorizing box 3 through the air inlet pipe 311. The air inlet pipe 311 is a telescopic hose. The first adsorption plate 331 and the second adsorption plate 341 inside the deodorizing box 3 can be used to achieve double adsorption of the flue gas, and the filter 35 is used for further adsorption, so as to reduce the impact of the odor generated during the welding process on the staff.
