Description

Technical Field

[0001] This invention belongs to the field of battery processing technology, and in particular to a battery processing apparatus. Background Technology

[0002] Current welding fixtures generally use side positioning and clamping. This positioning method uses clamping cylinders to clamp the battery cells. This can sometimes cause the battery components to shift, leading to poor welding. At the same time, existing welding fixtures rely on a large number of pneumatic parts for operation. If the assembly accuracy of the mechanism cannot be guaranteed, the lifespan of standard parts will be greatly affected, increasing costs significantly and also affecting the efficiency of assembly, debugging, and subsequent production. Summary of the Invention

[0003] To address the technical problem of insufficient positioning of battery components to be processed in existing technologies, a battery processing apparatus is proposed. The apparatus includes a moving part for positioning and moving a battery pad or the battery to be processed, and a first driving part for moving the moving part back and forth. When the first driving part moves along the Y-axis, the moving part also moves the battery pad back and forth along the Y-axis. Adjacent moving parts are connected by a connecting rod. The connecting rod includes a first connecting rod and a second connecting rod, which are connected by a connecting shaft. The ends of the first and second connecting rods away from the connecting shaft are movably connected to their respective adjacent moving parts. When the moving part moves, the shape between the first and second connecting rods can switch between an "I" shape and a "V" shape, allowing the battery pad or the battery to be processed to move along the X-axis according to the shape change between the first and second connecting rods.

[0004] Optionally, a roller mounting plate is provided, in which rollers are provided. The roller mounting plate is arranged in the X-axis direction and located on both sides of the connecting rod. The rollers are used to roll the battery to be processed.

[0005] Optionally, a pressing part and a fixture base plate are provided. The moving part and the first driving part are both mounted on the fixture base plate. The fixture base plate is also provided with a roller mounting plate, a pressing part and a second driving part. Under the action of the second driving part, the pressing part can drive the roller mounting plate to move up and down relative to the upper surface of the battery to be processed.

[0006] Optionally, a fixture base plate is provided, on which a welding fixture assembly for clamping a battery pad or a battery to be processed is mounted. The welding fixture assembly includes a connecting plate connected to the fixture base plate. One end of the connecting plate is connected to a first driving unit, and the other end is connected to a moving unit. When the first driving unit is working, the connecting plate can move back and forth, and the moving unit can move back and forth with the connecting plate. A first bearing seat is mounted on the fixture base plate, in which a first bearing and a first rotating shaft are mounted. A follower mounting block and a first pressure block are mounted on the first rotating shaft. The other end of the follower mounting block is connected to the moving unit. When the moving unit moves back and forth, the first rotating shaft and the first bearing cooperate to rotate the first rotating shaft. The first pressure block moves up and down with the rotation of the first rotating shaft. When it moves upward, it unlocks; when it moves downward, it presses.

[0007] Optionally, a pressing assembly is provided for unlocking and positioning the battery to be processed. The pressing assembly includes a first pressing pull-out unlocking part, which in turn includes a second driving part. One end of a guide part is connected to the second driving part, and a pressure plate is mounted on the other end of the guide part. The first pressing pull-out unlocking part also includes a pressing pad, which is mounted on a fixture base plate. A second bearing seat is mounted on the pressing pad, and a second bearing and a second rotating shaft are mounted on the second bearing seat. The pressing part for unlocking and positioning the battery to be processed is mounted on the second rotating shaft, which is also connected to a lower pressing block. When the second driving part drives the guide part to move up and down, the pressure plate presses down on the lower pressing block. When the lower pressing block moves downward, the second rotating shaft rotates accordingly, and the pressing part also rotates accordingly, thereby realizing the unlocking and positioning of the battery to be processed.

[0008] Optionally, the film pressing part has a front end and a rear end, the front end is provided with a roller mounting plate, and the roller mounting plate is provided with rollers.

[0009] Optionally, a welding fixture assembly and a fixture base plate are provided. There are multiple welding fixture assemblies, which are symmetrically arranged on both sides of the fixture base plate. Adjacent welding fixture assemblies are connected by a connecting rod.

[0010] Optionally, there are multiple welding fixture assemblies, and the moving parts of one welding fixture assembly and the moving parts of another welding fixture assembly are connected by a linkage.

[0011] Optionally, a cell pad is placed above the connecting rod, and the connecting rod includes a first connecting rod and a second connecting rod.

[0012] The first connecting rod and the second connecting rod are connected by a connecting shaft.

[0013] The first connecting rod and the second connecting rod are movably connected to the moving part. When the moving part moves, the first connecting rod and the second connecting rod can change from an "I" shape to a "V" shape.

[0014] The beneficial effects of this invention are as follows: It changes the way the welding fixture positions the battery cell, changing from the original single side positioning to vertical positioning of the battery cell pressing block. This means that the new fixture structure can meet some special design requirements and reduce design bottlenecks. Secondly, the use of many mechanical linkage structures in the design of the new fixture has greatly reduced the number of pneumatic components used in the fixture. This reduces many problems in later debugging and maintenance at the design level, and also reduces equipment costs. Attached Figure Description

[0021] The following is in conjunction with the instruction manual appendix. Figures 1 to 6 The specific implementation method is described below:

[0022] Reference Figure 2 and 6In one embodiment, a battery processing apparatus is provided, comprising a moving part for positioning and moving a battery pad or a battery to be processed, a first driving part 5-6 for driving the moving part to move back and forth, and a battery pad for placing the battery to be processed. When the first driving part 5-6 moves back and forth along the Y-axis, the moving part drives the battery pad to move back and forth along the Y-axis as well. There are multiple moving parts, and two adjacent moving parts are connected by a connecting rod 1. The connecting rod 1 is provided with a first connecting rod and a second connecting rod, which are connected by a connecting shaft. The ends of the first connecting rod and the second connecting rod away from the connecting shaft are movably connected to the moving part. When the moving part moves back and forth, the shape between the first connecting rod and the second connecting rod can change from an "I" shape to a "V" shape, and the battery pad can move left and right along the X-axis according to the shape change between the first connecting rod and the second connecting rod.

[0023] In this embodiment, refer to Figure 6 The system also includes a first drive unit for moving the movable part back and forth and a battery pad for placing the battery to be processed. The movable part can be a mechanism composed of a slide rail and a slider. The slider can move back and forth under the action of the first drive unit 5-6, thereby pushing the battery pad to move back and forth. There are multiple movable parts, which means two or more. For example, in the case of two, there are a first movable part and a second movable part. These two movable parts are arranged opposite each other. Since the first movable part and the second movable part are connected by a connecting rod 1, when the first drive unit 5-6 moves forward, the first movable part... The first and second moving parts move towards each other, changing the shape between the first and second connecting rods from an "I" shape to a "V" shape. At this time, the battery to be processed is clamped between the first and second moving parts, achieving positioning. Because the shape between the first and second connecting rods can change from an "I" shape to a "V" shape, the battery to be processed can move left or right. Similarly, when the first driving part 5-6 moves backward, the shape between the first and second connecting rods can change from a "V" shape to an "I" shape, thus unlocking. Therefore, positioning can be achieved using only one first driving part 5-6. However, in practical scenarios, two first driving parts 5-6 can also be used to control the positions of the two connecting parts, for example, one installed at the position of the first moving part and the other installed at the position of the second moving part.

[0024] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 3 , Figure 4 and 6The fixture is provided with a base plate 5-0, and the moving part and the first driving part 5-6 are both mounted on the base plate 5-0. The base plate 5-0 is also provided with a roller mounting plate 3-1-8, and a roller 3-1-9 is provided in the roller mounting plate 3-1-8. The roller mounting plate 3-1-8 is located in the X-axis direction and on both sides of the connecting rod 1. The roller 3-1-9 is used to roll the battery to be processed.

[0025] In this embodiment, the battery to be processed includes one or more components such as a blue film, a cell, and electrode sheets. When the shape between the first connecting rod and the second connecting rod changes from an "I" shape to a "V" shape, the battery pad can drive the battery to move along the X-axis, for example, from the right to the left. At this time, the rollers 3-1-9 precisely roll and press the upper surface of the battery to be processed, thereby pressing the blue film tightly onto the surface of the cell or flattening the electrode sheets. This invention achieves automated battery processing through the cooperation between the connecting rod 1, the first driving part 5-6, and the battery pad, resulting in a simple structure and significantly improved processing efficiency.

[0026] In one embodiment, reference Figure 4 It is equipped with a pressing part, which, under the action of the driving component, can drive the roller mounting plate 3-1-8 to move up and down relative to the upper surface of the battery to be processed, thereby achieving the purpose of applying different pressures to the battery to be processed.

One end of the connecting plate 5-1 is connected to a first driving unit 5-6, and the other end is connected to a moving unit. When the first driving unit 5-6 is working, the connecting plate 5-1 can move back and forth, and the moving unit can move back and forth with the connecting plate 5-1. A second... A bearing housing 5-2 is provided, in which a first bearing and a first rotating shaft 5-3 are installed. A follower mounting block 5-4 and a first pressing block 5-5 are installed on the first rotating shaft 5-3. The other end of the follower mounting block 5-4 is connected to the moving part. When the moving part moves back and forth, the first rotating shaft 5-3 and the first bearing cooperate with each other to make the first rotating shaft 5-3 rotate. The first pressing block 5-5 moves up and down with the rotation of the first rotating shaft 5-3. When it moves upward, it unlocks; when it moves downward, it presses.

[0031] In this embodiment, the moving part can be composed of a slider and a slide rail. The other end of the follower mounting block 5-4 is connected to the slider of the moving part, and the other end is the end away from the first rotating shaft 5-3.

The second rotating shaft is equipped with a pressing part 3-1-6 for unlocking and positioning the battery to be processed. The second rotating shaft is also connected to a lower pressing block 3-1-7. When the second driving part 3-1-1 drives the guide part 3-1-2 to move up and down, the pressure plate 3-1-3 presses down the lower pressing block 3-1-7. When the lower pressing block 3-1-7 moves down, the second rotating shaft rotates accordingly, and the pressing part 3-1-6 also rotates accordingly, thereby realizing the unlocking and positioning of the battery cell and the blue film adhesive.

[0033] In one embodiment, the pressing part 3-1-6 is divided into a front end and a rear end. The front end is provided with a roller mounting plate 3-1-8, and the roller mounting plate 3-1-8 is provided with a roller 3-1-9.
