Description

Technical Field

[0001] This utility model relates to a fixing device for lithium battery processing, belonging to the field of lithium battery processing technology. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Lithium batteries are divided into lithium batteries and lithium-ion batteries. Lithium batteries need to be fixed during processing to facilitate the operation of the operator.

[0003] When multiple lithium batteries are used simultaneously, they need to be fixed together. Existing lithium battery processing fixing devices have a single fixing position, and the fixing effect is not good enough when fixing multiple lithium batteries.

[0004] This utility model proposes a new solution to the above problems. Utility Model Content

[0005] The main purpose of this utility model is to solve the problem of insufficient fixing effect when fixing multiple lithium batteries, and to provide a fixing device for lithium battery processing.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

The surface of the limiting frame is slidably connected to symmetrically distributed connecting frames. The surface of the connecting frames is fixedly connected to baffles. The inner wall of the limiting frame is fixedly connected to symmetrically distributed electric push rods. The output end of the electric push rod is fixedly connected to a fixing plate. The surface of the baffle is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to the baffle.

[0008] Preferably, the driving mechanism includes a baffle fixedly mounted on the surface of the limiting frame, and a drive motor is fixedly connected to the surface of the baffle.

[0015] Preferably, a support foot is fixedly connected to the lower surface of the base, and the support foot is made of wear-resistant rubber.

[0016] Preferably, the lower surface of the support foot is provided with adsorption holes.

[0017] The beneficial technical effects of this utility model are as follows: The lithium battery is placed in the limiting frame, then the baffle is moved so that the surface of the lithium battery contacts the limiting frame. Then, the electric push rod is activated, extending to push the fixing plate. The fixing plate slides inside the sliding groove, thus preventing movement interference between the fixing plate and the baffle.

[0026] like Figures 1-6 As shown in the figure, this embodiment provides a fixing device for lithium battery processing, including a base 1 and a limiting frame 2 fixedly installed on the upper surface of the base 1. A driving mechanism is provided on the limiting frame 2. A symmetrically distributed connecting frame 7 is slidably connected to the surface of the limiting frame 2. A baffle 13 is fixedly connected to the surface of the connecting frame 7. A symmetrically distributed electric push rod 11 is fixedly connected to the inner wall of the limiting frame 2. A fixing plate 12 is fixedly connected to the output end of the electric push rod 11. A sliding groove 14 is opened on the surface of the baffle 13. The inner wall of the sliding groove 14 is slidably connected to the baffle 13. The lithium battery is placed into the limiting frame 2. In the positioning frame 2, the baffle 13 is moved so that the surface of the lithium battery contacts the positioning frame 2. Then, the electric push rod 11 is activated, and the electric push rod 11 extends to push the fixing plate 12 to move. The fixing plate 12 slides inside the sliding groove 14, so the fixing plate 12 is not easy to interfere with the movement of the baffle 13. Through the cooperation of the fixing plate 12 and the positioning frame 2, the lithium battery is fixed in the second direction. Then, the baffle 13 applies pressure to the lithium battery. Through the cooperation of the baffle 13 and the positioning frame 2, the lithium battery is fixed in the first direction, and the lithium battery is fixed from the side.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the drive mechanism includes a cover 3 fixedly mounted on the surface of the limiting frame 2. The cover 3 is fixedly positioned on the rear surface of the limiting frame 2. A drive motor 4 is fixedly connected to the surface of the cover 3. A connecting seat 8 is fixedly connected to the surface of the connecting frame 7. A screw hole 16 is provided on the surface of the connecting seat 8. A lead screw 10 is rotatably connected to the inner wall of the cover 3. The inner wall of the screw hole 16 is threadedly connected to the lead screw 10. A transmission pulley 6 is fixedly connected to one end of the lead screw 10. A drive pulley 5 is rotatably connected to the inner wall of the cover 3. The cover 3 shields the lead screw 10, the drive pulley 5, and the transmission pulley 6, preventing workers from being injured and improving the workers' work efficiency. For safety, the drive pulley 5 and the transmission pulley 6 are connected by a belt drive. The output end of the drive motor 4 is connected to the drive pulley 5. The surface of the limit frame 2 is provided with a mating groove 9. The inner wall of the connecting frame 7 is fixedly connected to the connecting block 15. The inner wall of the mating groove 9 is slidably connected to the connecting block 15. The drive motor 4 drives the drive pulley 5 to rotate. The drive pulley 5 is driven by the belt, thereby driving the transmission pulley 6 to rotate. The transmission pulley 6 drives the lead screw 10 to rotate. Through the threaded engagement between the lead screw 10 and the screw hole 16, the connecting frame 7 is driven to move through the connecting seat 8, thereby driving the baffle 13 to move.

[0028] In this embodiment, as Figure 1 and Figure 6 As shown, a support foot 17 is fixedly connected to the lower surface of the base 1. The support foot 17 is made of wear-resistant rubber, and an adsorption hole 18 is provided on the lower surface of the support foot 17. The base 1 is supported by the support foot 17. The support foot 17 is attached to the table. Then, the base 1 is pressed down, which causes the support foot 17 to deform and expel some of the air from the adsorption hole 18. When the support foot 17 returns to its original position, a negative pressure is formed inside the adsorption hole 18, thereby fixing the base 1 to the table. During operation, the base 1 is not easy to move.

[0029] In this embodiment, as Figures 1-6 As shown in the figure, the working principle of the fixing device for lithium battery processing provided in this embodiment is as follows:

[0030] Step 1: Place the lithium battery into the limiting frame 2;

[0031] Step 2: The drive motor 4 drives the active pulley 5 to rotate. The active pulley 5 is driven by the belt, which in turn drives the transmission pulley 6 to rotate. The transmission pulley 6 drives the lead screw 10 to rotate. Through the threaded engagement between the lead screw 10 and the screw hole 16, the connecting bracket 7 is driven to move through the connecting seat 8, which in turn drives the baffle 13 to move, so that the surface of the lithium battery contacts the limiting frame 2.

[0032] Step 3: The electric push rod 11 extends and pushes the fixing plate 12 to move, thereby fixing the lithium battery in the second direction;

[0033] Step four: Apply pressure to the lithium battery through the baffle 13, and fix the lithium battery in the first direction through the cooperation of the baffle 13 and the limiting frame 2, thus fixing the lithium battery from the side.

Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
