Description

Technical Field

[0001] The utility model relates to the field of battery module manufacturing, in particular to a battery module aluminum bar welding tool. Background Art

[0002] The battery module is an intermediate energy storage unit between the battery cell and the battery pack. It forms a modular battery pack by connecting multiple battery cells in series and parallel, and adding auxiliary structural parts that play the role of collecting current, collecting data, and fixing and protecting the battery cells.

[0003] During the welding process of the battery module, a tool is required to press the aluminum busbar. However, the existing welding tool is one-piece. After several uses, the part pressing the aluminum busbar is easily damaged by the high temperature and sparks of the laser. Therefore, the entire tool needs to be replaced, which wastes manufacturing costs. In addition, the tool is difficult to lock with the battery module, making replacement more troublesome. Therefore, we propose a new battery module aluminum busbar welding tool, which aims to quickly replace damaged parts, improve replacement efficiency and reduce tooling costs. Utility Model Content

A quick locking pin is installed on the pressure plate. The pressure plate is detachably mounted on the top surface of the placement plate through the quick locking pin and supports the top surface of the pressure blocks.

[0007] Preferably, the pressing block positioning hole is a stepped hole, and the pressing block includes a column with a vertical through hole and a flange extending outward from the upper end of the column. The pressing block is placed in the pressing block positioning hole from top to bottom, and the flange of the pressing block is placed on the stepped surface of the pressing block positioning hole.

[0008] Preferably, the pressing block is made of copper.

[0009] Preferably, a receiving hole for accommodating the lower end of the quick locking pin is provided on the placement plate corresponding to the position of the quick locking pin, and a groove for accommodating the steel ball of the quick locking pin is provided on the hole wall of the receiving hole.

[0010] Preferably, a quick locking pin is installed at each end of each pressing plate.

[0011] Preferably, the quick locking pin is a button-type quick locking pin.

[0012] Preferably, a row of pressing blocks is provided on the placement plate corresponding to each row of battery cells, and clearance holes are provided on the pressing blocks corresponding to the battery cell pole positions of the battery module. Two pressing plates are arranged above each row of pressing blocks, and the clearance holes of each row of pressing blocks face the gap between the two pressing plates.

[0013] The utility model has the following beneficial effects:

[0014] The pressing block and the placement plate are connected by a quick locking pin.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] like Figures 1 to 5 As shown, this embodiment discloses a battery module aluminum bar welding tool, including a placement plate 1, a plurality of pressing blocks 2 and a plurality of pressing plates 3.

[0023] The placement plate 1 is provided with a removable pressure block 2 at each aluminum row 4 corresponding to the battery module. Clearance holes 5 are provided on the pressure blocks 2 at positions corresponding to the battery cell posts. Clearance holes 5 include, but are not limited to, circular holes, polygonal holes, and irregularly shaped holes. In this embodiment, the clearance holes 5 are preferably circular vertical through-holes.

[0024] The pressing block 2 includes a column 21 having a vertical through-hole and a flange 22 extending outward from the upper end of the column 21. A pressing block positioning hole 6 is provided on the placement plate 1 corresponding to each pressing block 2. The pressing block positioning hole 6 is a stepped hole. The flange 22 of the pressing block 2 is positioned on the stepped surface of the pressing block positioning hole 6, and the bottom end of the pressing block 2 protrudes from the bottom surface of the placement plate 1. In this embodiment, the outer contour of the flange 22 is square, but in other embodiments it is not limited to this. For example, it can also be circular. In other embodiments, the pressing block 2 can also adopt other shapes to cooperate with the placement plate 1 to limit the position.

[0025] The top surface of the pressing block 2 contacts the bottom surface of the pressing plate 3, which presses the pressing block 3. The pressing plate 3 and the placement plate 1 are quickly connected. Specifically, a number of quick locking pins 7 are installed on the pressing plate 3. The pressing plate 3 and the placement plate 1 are connected via the quick locking pins 7. The placement plate 1 has a receiving hole for accommodating the lower end of the quick locking pin 7 at the position corresponding to the quick locking pin 7. The hole wall of the receiving hole is provided with a groove for accommodating the steel ball 8 of the quick locking pin 7. Quick locking pins (also known as quick locks, quick latches, and quick release pins) are existing technology and can be purchased on the market. Preferably, a button-type quick locking pin is used.

[0026] As shown in the figure, the battery module has two rows of cells. A row of pressing blocks 2 is placed on the placement plate 1, corresponding to each row of cells. Two pressing plates 3 are placed above each row of pressing blocks 2, with the clearance holes 5 of each row of pressing blocks 2 facing the gap between the two pressing plates 3. Preferably, a quick-locking pin 7 is installed at each end of each pressing plate 3. A single person can remove a pressing plate 3 by pressing the two quick-locking pins 7 with both hands.

[0027] Pressing the button of the quick locking pin 7 can make the steel ball 8 retract into the inside of the quick locking pin 7, that is, make the steel ball 8 disengage from the groove, so that the quick locking pin 7 can be pulled out from the placement plate 1. When it is necessary to replace the pressure block 2, you only need to press the button of the quick locking pin with both hands to lift the pressure plate 3 upwards, and then directly replace the damaged pressure block 2. After the pressure block 2 is replaced, the quick locking pin 7 is inserted into the placement plate 1, and the steel ball 8 is stuck in the groove, and the pressure block 2 is pressed by the pressure plate 3. The quick locking pin 7 is fixed together with the pressure plate 3, and the pressure block is connected to the placement plate 1 with the quick locking pin 7. After removing the pressure plate 3, the pressure block 2 can be quickly replaced, which is convenient for replacement and maintenance and improves production efficiency.

[0028] The pressing block 2 of this embodiment is made of copper. In other embodiments, the material of the pressing block 2 is not limited to this. The quick locking pin 7 is a prior art and can be purchased from the market.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate from the spirit and scope of the technical solutions of the embodiments of the present invention. Therefore, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present invention.
