Description

Technical Field

[0001] This utility model relates to the field of battery handling technology, specifically to a welding tray mechanism for the end side plates of single and double row lithium battery modules. Background Technology

[0002] Lithium-ion battery modules are formed by stacking and assembling multiple battery cells. Conventional power battery modules are classified as single-row, dual-row, or triple-row. In existing technologies, conventional modules are assembled from end plates, side plates, and multiple battery cells. There are also processes where the end plates and side plates are laser-welded together. Since both single-row and dual-row modules require laser welding of the end plates and side plates, a welding fixture tray compatible with both single-row and dual-row configurations is needed.

[0003] Reference: CN201110211015.9 Battery trays applicable to automated lithium battery formation production lines, which design the structure of battery brackets and tray frames to make the battery trays suitable for placing lithium batteries of different types and sizes with single-sided and double-sided electrode outlets.

[0004] However, the method described in the reference involves adjusting the spacing by passing a mandrel through a mandrel hole to install and clamp the battery. This method requires manual adjustment and locking, which is not conducive to handling batteries in mass production.

[0005] For example, CN201720682813.2 describes a tray for transporting different lithium battery modules. It uses a guide rail to move and clamp the different modules. However, on the one hand, the clamping part uses a spring, which is easy to fall off under vibration; on the other hand, it lacks a locking mechanism to ensure the restriction of the movement direction.

[0006] To address this issue, we provide a pusher clamp with adjustable mounting position. Utility Model Content

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The guide rail preamplifier is input through an external pneumatic component, such as... Figure 8 As shown, a pneumatic pipe is installed between the guide rail clamp and the sliding plate.

Simultaneously, the slider's movement distance on the linear guide rail can be achieved by an electric drive component. The specific electric drive and pneumatic components can be controlled using existing methods, and the output time of the electric drive corresponds to different movement distances and different module sizes, which cannot be precisely described in detail.

[0048] like Figure 1 As shown, the two sets of POM pads 4 are arranged in parallel, and each set of POM pads 4 is bent; positioning holes 41 are provided on the POM pads 4, and the POM pads 4 are detachably connected to the base support plate 1; the POM pads are antistatic boards made of thermoplastic engineering plastic sheets formed by high-temperature extrusion of polyoxymethylene plastic particles, also known as antistatic acetal plates or antistatic polyoxymethylene boards, which can play a good antistatic role when used in battery module handling.

[0049] A partition 42 is included in the middle of the two sets of POM pads 4, and the partition 42 connects and closes the two sets of POM pads 4; the length of the partition 42 is greater than the length of the sliding body.

[0050] The width of the single-row module 7 is greater than the spacing between the two sets of POM pads 4.

[0051] The partition 42 is equipped with a single-row module contour end plate 5 and a double-row module contour end plate 6; the single-row module 7 and the double-row module 8 are both mounted on two sets of POM pads 4.

The transition plate 15 and the single-row module contouring end plate 16 are detachably connected.

[0054] The sliding plate 9 drives the single-row module contouring end plate 16 to press the single-row module 7 toward one side of the single-row module contouring end plate 5.

[0055] like Figure 3 As shown, the double-row module contouring end plate mechanism includes a second transition plate 17 and a second double-row module contouring end plate 18. The second double-row module contouring end plate 18 and the first double-row module contouring end plate 6 are located on both sides of the double-row module 8. The connecting frame 11 located outside the double-row module 8 is connected to the second transition plate 17, and the second transition plate 17 and the second double-row module contouring end plate 18 are detachably connected.

[0056] The sliding plate 9 drives the double-row module contouring end plate 18 to press the double-row module 8 toward one side of the double-row module contouring end plate 6.

[0057] The length of the second transition plate 17 is greater than the length of the first transition plate 15, and the length of the second double-row module contoured end plate 18 is greater than the length of the second single-row module contoured end plate 16.

[0058] This invention achieves movement by installing a sliding body on a linear guide rail, and clamping by the movement of the second double-row module contouring end plate toward the first double-row module contouring end plate, and the second single-row module contouring end plate toward the first single-row module contouring end plate. A guide rail clamp is installed to achieve rapid positioning of the sliding body on the linear guide rail. By separately setting up single-row module contouring end plate mechanisms and double-row module contouring end plate mechanisms, this invention can simultaneously achieve rapid positioning and transport of two sets of modules on the linear guide rail.

[0059] Example 2

[0060] like Figure 4-8 As shown, another embodiment of the present invention is provided. Based on embodiment 1, the four corners of the base support plate 1 are rounded and rollers 19 are installed. A position hole 20 is installed on the base support plate 1, and a positioning plate 21 is installed outside the position hole 20. The position hole 20 penetrates the base support plate 1.

[0061] like Figure 5 As shown, the single-row module contouring end plate 216 and the single-row module contouring end plate 5 are provided with a shaping plate 22 on the side facing the single-row module 7.

[0062] like Figure 8 As shown, the double-row module contouring end plate 218 and the double-row module contouring end plate 16 are provided with a shaping plate 23 on the side facing the double-row module 8.

[0063] Guide rail clamps 3 are installed at the bottom of the sliding plate 9; the single-row module contour end plate 2 16, the single-row module contour end plate 1 5, the double-row module contour end plate 2 18 and the double-row module contour end plate 1 6 are all provided with vertical cutouts.

[0065] The slider 10 is mounted on the linear guide rail 2 and connected to the sliding plate at the top. The POM pad 4 is connected to the base support plate 11, and a positioning screw is installed through the positioning hole. The guide rail clamp is located at the bottom of the sliding plate and mounted on the linear guide rail. The guide rail clamp generates friction to quickly position the sliding plate on the linear guide rail.

[0066] Both the single-row module contouring end plate mechanism and the double-row module contouring end plate mechanism are connected to the linear guide rail, slider, and guide rail clamp. They can be adjusted in length under ventilated conditions to achieve fit between the single-row module contouring end plate mechanism and the single-row module or double-row module. After the fit is completed and compressed, the air source is disconnected, and the guide rail clamp locks, forming a pressure holding effect. This prevents the module from shifting during subsequent welding, improving the pass rate and reducing the slippage of the module due to pallet slippage during transport.

[0067] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
