Description

Technical Field

[0001] The utility model relates to the field of battery recycling, in particular to a winding battery auxiliary disassembly tooling. Background Technique

[0002] The wound-core battery, also known as the battery cell, is a type of battery composed of battery cells formed by winding. The positive electrode sheet, separator, and negative electrode sheet of the wound-core battery are all tightly adhered. The fully charged disassembly interface of the battery negative electrode is a simple method to judge the long-term performance of the battery. After the battery trial production is completed, the interface disassembly and confirmation is an essential link, and a normal interface is the most basic guarantee to ensure excellent long-term performance of the battery. For large-capacity batteries such as square aluminum shells, at least two people are required to cooperate during disassembly, and a large disassembly space and site are needed.

[0003] At present, the disassembly of square aluminum shell batteries mostly adopts manual disassembly. Mainly, workers use a small knife and pliers to disassemble the battery manually, and then unfold the wound core and lay it flat on the bottom surface. When separating the negative electrode sheet from the positive electrode sheet, two people are required to cooperate to lift the electrode sheet at both ends. Because the existing wound core is too long, the manual process requires multiple operations to separate the electrode sheet and the separator, resulting in low manual disassembly efficiency, and the large disassembly room site will also correspondingly increase the energy consumption cost.

Specific embodiments

[0022] The following further describes the present utility model in detail:

[0023] As Figures 1 to 5 shown, the present utility model provides a winding battery auxiliary disassembly tooling, including a disassembly table 1, a mounting rack 2 fixedly connected to the bottom of the disassembly table 1, a placement table 3 movably installed on the top of the disassembly table 1 and a winding assembly 4 arranged outside the placement table 3, a transmission assembly 5 fixedly installed inside the mounting rack 2. The winding assembly 4 includes a second base 41 fixedly installed on the top of the disassembly table 1, a second turntable 42 movably clamped on the top of the second base 41, a rotating shaft 43 fixedly connected to the bottom of the second turntable 42 and penetrating the disassembly table 1, a winding frame 44 fixedly installed on the top of the second turntable 42, a sliding groove 45 opened outside the top of the second turntable 42, a guide rod 46 fixedly installed inside the sliding groove 45, a spring 47 and a sliding seat 48 movably clamped on the outside of the guide rod 46, and a roller 49 rotatably installed inside the sliding seat 48.

[0024] By fixing the taken-out core on the placing table 3 and fixing its positive electrode sheet, negative electrode sheet and separator on the outside of the winding rack 44 respectively, driving the second turntable 42 to rotate through the driving of the transmission assembly 5 to wind the positive electrode sheet, negative electrode sheet and separator on the outside of the winding rack 44 respectively. As the winding thickness increases, the sliding seat 48 is pushed to move outward along the sliding groove 45 to squeeze the spring 47, thereby ensuring the winding tightness of the positive electrode sheet, negative electrode sheet and separator. The operation is simple and can be operated by a single person. At the same time, the disassembly efficiency is improved and the site occupation is reduced. By placing the core on the first turntable 32 and sleeving it outside the fixed rod 38, and then rotating the handwheel 35, since the external thread 36 on the outside of the rotating rod 34 is arranged in opposite directions on both sides of the fixed rod 38, the rotation of the rotating rod 34 drives the sliding block 37 located in the installation groove 33 to drive the fixed rod 38 to move outward to clamp the core on the outside, thereby facilitating the fixing of the core and facilitating the winding operation.

[0025] As Figure 3 shown in the figure, the placing table 3 includes a first base 31 fixedly installed on the top of the disassembly table 1. The top of the first base 31 is movably clamped with a first turntable 32. An installation groove 33 is opened at the top of the first turntable 32. A rotating rod 34 is rotatably installed inside the installation groove 33. A handwheel 35 is fixedly installed on the outside of the rotating rod 34. An external thread 36 is arranged on the outside of the rotating rod 34. A sliding block 37 is threadedly installed on the outside of the external thread 36. The top of the sliding block 37 is fixedly connected with a fixed rod 38.

[0026] By placing the core on the first turntable 32 and sleeving it outside the fixed rod 38, and then rotating the handwheel 35, since the external thread 36 on the outside of the rotating rod 34 is arranged in opposite directions on both sides of the fixed rod 38, the rotation of the rotating rod 34 drives the sliding block 37 located in the installation groove 33 to drive the fixed rod 38 to move outward to clamp the core on the outside, which is convenient for clamping different cores from the inside, facilitating fixing, and facilitating the winding operation.

[0027] As Figure 5 shown in the figure, the transmission assembly 5 includes a synchronous pulley 51. The synchronous pulley 51 is fixedly installed on the outside of the rotating shaft 43. A synchronous toothed belt 52 is movably installed on the outside of the synchronous pulley 51. A driving motor 53 connected to the rotating shaft 43 is fixedly installed at the bottom of the installation frame 2.

[0028] The driving motor 53 can drive the connected rotating shaft 43 to rotate, and cooperate with the corresponding synchronous pulley 51 installed on the outside of the adjacent rotating shaft 43 and the transmission of the synchronous toothed belt 52, so as to facilitate the synchronous winding and separation of the positive electrode sheet, negative electrode sheet and separator.

[0029] As Figure 4 shown in the figure, the sliding seat 48 is arranged on the outside of the winding rack 44, and the inner side of the sliding seat 48 is arc-shaped.

[0030] It is arranged outside the winding frame 44 through the sliding seat 48, and the inner side thereof is arc-shaped, so as to push the sliding seat 48 to move outward as the winding thickness increases, and the winding tightness is ensured through the sliding seat 48.

[0031] As Figure 4 shown, the roller 49 is made of rubber.

[0032] The roller 49 is made of rubber and rolls in contact with the positive electrode plate, negative electrode plate and separator, so as to press them and ensure the winding tightness.

[0033] As Figure 1 shown, the winding assemblies 4 are arranged at equal intervals on the rear side of the placing table 3.

[0034] The number of the winding assemblies 4 is determined according to the quantities of the positive electrode plate, negative electrode plate and separator. At the same time, the winding assemblies 4 are arranged in an annular and equidistant manner outside the placing table 3, and the distances between the winding assemblies 4 and the placing table 3 are equal, so as to ensure synchronous winding of the positive electrode plate, negative electrode plate and separator.

[0035] As Figure 2 shown, a partition block 39 is fixedly installed inside the installation groove 33, and external threads 36 are symmetrically arranged on the front and rear sides of the partition block 39 and are arranged in opposite directions.

[0036] The external threads 36 separated by the partition block 39 are arranged in opposite directions, so that the sliding block 37 is driven to move oppositely and approach or separate along the external threads 36 by rotating the rotating rod 34, so as to clamp the winding core.

[0037] As Figure 3 and Figure 4 shown, ball bearings 6 are movably clamped inside both the base one 31 and the base two 41.

[0038] The ball bearings 6 are located inside the base one 31 and the base two 41, so as to reduce the friction force and wear when the turntable one 32 and the turntable two 42 rotate.

[0039] Next, the working principle of the winding battery auxiliary disassembly tooling will be specifically described.

[0040] As Figures 1 to 5As shown, by placing the battery on the disassembly table 1, then cutting open the battery with a knife and pliers to take out the core, placing the core on the first turntable 32 and sleeving it outside the fixed rod 38, and then rotating the handwheel 35. Since the external threads 36 on the outside of the rotating rod 34 are arranged in opposite directions on both sides of the fixed rod 38, the rotation of the rotating rod 34 drives the slider 37 located in the installation groove 33 to drive the fixed rod 38 to move outward to clamp the outer core. Subsequently, by removing the termination tape on the core and clamping the negative electrode sheet, positive electrode sheet and separator respectively outside the winding rack 44 by using the winding rack 44. Then, by controlling and starting the drive motor 53, the rotation of the drive motor 53 drives the connected rotating shaft 43 to rotate. At the same time, the synchronous pulley 51 outside the rotating shaft 43 cooperates with the synchronous toothed belt 52 for transmission to drive the second turntable 42 to rotate synchronously. The rotation of the second turntable 42 drives the winding racks 44 on its top to rotate respectively. The rotation of the winding racks 44 winds the positive electrode sheet, negative electrode sheet and separator respectively. And through the positive electrode sheet, negative electrode sheet and separator contacting the rollers 49 outside the winding rack 44, the rollers 49 push the sliding seat 48 to move in and out along the sliding groove 45 as the winding thickness increases, squeezing the spring 47, so that the positive electrode sheet, negative electrode sheet and separator are closely attached to complete the winding work.

[0041] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
