Description

Technical Field

[0001] The utility model relates to the field of battery cell assembly, and particularly to a tooling plate for a module line. Background Art

[0002] In modern industrial production, automation and precision are key factors in improving efficiency and quality. However, in the manufacturing process of battery modules, the currently widely used manual operation method has many problems, which not only affect production efficiency but also may reduce product quality.

[0003] First of all, manual operation has limitations in precision. During the cell stacking process, workers need to manually place the cells on the conveyor line in a specific order and position to form a module. This process requires a high degree of concentration and precision, but human factors often lead to inaccurate positioning, thus affecting the overall structure and stability of the module. Even a small displacement or angular deviation of the cells may cause problems in the subsequent welding process, such as uneven welding or even welding failure. Secondly, the efficiency of manual operation is relatively low. In a high-speed production environment, relying on manual labor for cell stacking and module placement is not only slow but also easily affected by worker fatigue and mood swings. This not only limits the production capacity of the production line but also may lead to an increase in production costs. Moreover, manual operation also has potential safety hazards. During the welding process of battery modules, high temperature and strong light are inevitable, and harmful gases and sparks may be generated during the welding process. Prolonged exposure to such an environment poses a threat to the health of workers.

[0004] Therefore, there is an urgent need to invent a tooling plate for a module line, which can realize the mechanized operation of cells during the stacking process, ensure the precise alignment of cells, thus significantly reducing the errors caused by manual operation, and further improving the structural stability of the battery module and the overall quality of welding.

Detailed Embodiments

[0034] The following will describe a modular line tooling plate of the present utility model in more detail with reference to the accompanying drawings, which show the preferred embodiments of the present utility model. It should be understood that those skilled in the art can modify the present utility model described herein while still achieving the advantageous effects of the present utility model. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present utility model.

[0035] In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the accompanying drawings. According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of facilitating and clearly assisting in explaining the embodiments of the present utility model.

[0036] As Figure 1 and Figure 2 shown, this embodiment provides a modular line tooling plate, including: a bottom plate, an upper fixing part, a lower fixing part, a left pressing part, and a right pressing part; the upper fixing part, the lower fixing part, the left pressing part, and the right pressing part are sequentially arranged end to end on the bottom plate and enclose an installation space; the left pressing part and the right pressing part are oppositely arranged; the upper fixing part and the lower fixing part are oppositely arranged.

[0037] In this embodiment, the left pressing part includes: a mounting plate 1 mounted on the bottom plate; a pressing plate 2 movably arranged on the mounting plate 1 along a direction away from or close to the right pressing part, that is, along the X-axis direction; a blocking member arranged on the mounting plate 1, and the blocking member is used to block the sliding of the pressing plate 2.

[0038] Specifically, the left pressing part includes a pin shaft 4 and a plurality of pin holes 3; the plurality of pin holes 3 are evenly arranged on the mounting plate 1 along a direction away from or close to the right pressing part; the pin shaft 4 is arranged on the pressing plate 2, on the same axis as the plurality of pin holes 3, and can be inserted into the pin holes 3 along the Z-axis direction.

[0039] Among them, there are a plurality of pin holes 3, which are evenly arranged on the mounting plate 1. When the pressing plate 2 slides to a predetermined position, the pin shaft 4 can be inserted into the pin holes 3, so as to play a fixing role and prevent the pressing plate 2 from sliding.

[0040] In this example, the left pressing part further includes: a spring (not shown in the figure), sleeved on the pin shaft 4, with one end fixed on the pin shaft 4 and the other end abutted against the pressing plate 2. Adding a spring can provide a restoring force for the pin shaft 4. When it is necessary to move the pressing plate 2, manually lift the pin shaft 4. At this time, the spring is in a compressed state. When the pressing plate 2 moves to a predetermined position and the pin shaft 4 is aligned with the pin hole 3 at the predetermined position, the pin shaft 4 can be released at this time, and it can be inserted into the pin hole 3 by means of the restoring force of the spring.

[0041] In addition, in order to facilitate the pin shaft 4 to be more easily guided into the pin hole 3, a guide plate 6 can be provided on the left pressing part. The guide plate 6 is arranged between two adjacent pin holes 3, and the guide plate 6 is trapezoidal in shape, and the surface is an inclined surface that can guide the pin shaft 4 towards the pin hole 3.

[0042] As Figure 3 shown, a slide rail 5 is provided on the mounting plate 1, a slider 7 is fixed under the pressing plate 2, and a chute 8 matching the slide rail 5 is provided on the bottom surface of the slider 7. The slider 7 is slidably arranged on the slide rail 5, so that the pressing plate 2 can reciprocate along the X-axis.

[0043] In this example, a first stop bar 9 is detachably arranged at one end of the left pressing part facing the right pressing part. The first stop bar 9 can be replaced based on actual needs to achieve secondary adjustment of the pressing of the battery cell.

[0044] As Figure 4 shown, in a specific example, the right pressing part includes: a base 10, mounted on the bottom plate; at least one mounting hole, provided on the base 10; a pressing assembly, arranged on the base 10 through the mounting hole, and the pressing assembly can rotate along the center line of the mounting hole for convenient adjustment.

[0045] Specifically, the pressing assembly includes: a pressure rod 11 moving along the X-axis through the mounting hole, a connecting rod 13 connected to the pressure rod 11, and an L-shaped rod 12 connected to the connecting rod 13. One end of the connecting rod 13 is hinged to the bent part of the L-shaped rod 12, and the other end is hinged to the base 10. This pressing assembly adopts a clever locking structure design, and its working principle is as follows:

[0046] In the initial state, the L-shaped rod 12 is in a horizontal position, and at this time the pressure rod 11 is in a state away from the battery cell. When it is necessary to press the battery cell, the operator rotates the L-shaped rod 12 from the horizontal position to the vertical position (perpendicular to the horizontal plane). During this process, the bent part of the L-shaped rod 12 moves along an arc trajectory, pulling the connecting rod 13. The connecting rod 13 then drives the pressure rod 11 to move towards the direction close to the left pressing part, so that the pressure rod 11 presses the battery cell to complete the locking.

[0047] When it is necessary to release the battery cell, rotate the L-shaped rod 12 from the vertical position back to the horizontal position. This action pushes the connecting rod 13, which in turn drives the pressing rod 11 to move away from the left pressing part, causing the pressing rod 11 to move away from the battery cell and achieving release.

[0048] The self-locking mechanism in the pressed state is reflected in that when the L-shaped rod 12 is in the vertical position, the L-shaped rod 12, the connecting rod 13, and the base 10 are almost in a straight line. In this geometric configuration, it is difficult for an external force to push the pressing rod 11, thus achieving self-locking and maintaining a stable pressing state.

[0049] This locking structure design is based on the principle of a planar linkage mechanism. A planar linkage mechanism refers to a mechanism in which multiple rigid components (linkages) are connected by hinged joints and all motions are restricted within the same plane. In this design, the L-shaped rod 12 serves as the crank, the connecting rod 13 serves as the linkage, and the pressing rod 11 serves as the slider, jointly forming a modified crank-slider mechanism. This mechanism can convert the rotational motion of the L-shaped rod 12 into the linear reciprocating motion of the pressing rod 11. Through carefully designed geometric relationships, it realizes the conversion of motions in different directions within the same plane and effectively controls the pressing and releasing actions of the pressing rod 11.

[0050] The advantages of this mechanism design are simple structure, convenient operation, and good self-locking performance, which can reliably achieve the rapid pressing and releasing of the battery cell. By simply rotating the L-shaped rod 12, the pressing or releasing of the battery cell can be completed, greatly improving the operation efficiency and reliability.

[0051] In this example, there are two sets of the pressing assemblies. The purpose of this setting is: on the one hand, to meet the pressing of a single battery assembly; on the other hand, when facing a set of battery assemblies, to ensure that both sets of battery cells in the set of battery assemblies can receive uniform forces.

[0052] In this example, two sets of pressing components are provided. The purpose of this design is multi-faceted: First, when pressing a single battery component, the two sets of pressing components can operate independently. The operator can choose to use one of the two sets of pressing components for pressing according to the size and position of a single battery component. Rotate the L-shaped rod 12 from the horizontal position to the vertical position, and through the transmission of the connecting rod 13 and the pressing rod 11, precise pressing of a single battery component can be achieved. This flexibility enables the pressing system to adapt to battery components of different specifications and quantities. Second, when facing a set of battery components, the two sets of pressing components can work simultaneously to ensure that both sets of battery cores in the set of battery components can receive uniform force: Place the set of battery components at an appropriate position between the two sets of pressing components, and simultaneously or sequentially operate the L-shaped rods 12 on both sides to rotate them from the horizontal position to the vertical position; during this process, the connecting rods 13 and the pressing rods 11 on both sides will move synchronously. Since the structures of the two sets of pressing components are exactly the same and the operations are consistent, the pressures they exert are theoretically equal.

[0053] As Figure 5 and Figure 6 shown, in this embodiment, a left step portion 14 is provided at one end of the left pressing portion close to the right pressing portion; a right step portion 15 is provided at one end of the right pressing portion close to the left pressing portion, and the left step portion 14 and the right step portion 15 are symmetric about the Y axis. The battery core is disposed between the left step portion 14 and the right step portion 15, and the end plate is disposed above the left step portion 14 and the right step portion 15.

[0054] Further, the upper fixing portion is a second retaining bar 18, and the lower fixing portion is a third retaining bar 19. The second retaining bar 18 and the third retaining bar 19 are disposed on the bottom plate in parallel and detachably; the second retaining bar 18 is provided with steps and is adapted to the left step portion 14 and the right step portion 15 for adjusting the distance of the battery core group in the Y-axis direction and keeping it consistent. The function of the third retaining bar 19 is to press the battery core group in the Y-axis direction through the third retaining bar 19 after the battery core group is pressed in the X-axis direction.

[0055] The specific usage method of this embodiment is as follows: Place the end plate on the left pressing portion, limit the end plate through the left pressing portion and the fixing portion, sequentially place the first row of battery cores into the upper fixing portion, and use the second retaining bar 18 to press the first row of battery cores in the Y-axis direction. After the first row of battery cores is fixed, do not remove them. Then, sequentially place the second row of end plates and battery cores into the lower fixing portion, and use the third retaining bar 19 to press the second row of battery cores. At this time, place the second retaining bar 18 between the first row of battery cores and the second row of battery cores to play an equal-distance partitioning role for the two rows of battery cores, rotate the right pressing portion to press the module in the X-axis direction, and use the third retaining bar 19 to align and press for adjustment.

[0056] In summary, a tooling board for a module line proposed by the present utility model includes an upper fixing part, a lower fixing part, a left pressing part, and a right pressing part provided on a bottom plate. Among them, the left pressing part and the right pressing part are symmetrically arranged, and together with the upper fixing part and the lower fixing part, they form a space for installing battery cells. By placing the battery cells to be assembled in this installation space and using the pressing parts for positioning and fixing, this tooling board can achieve automated operation during the stacking process of the battery cells.
