Description

Technical Field

[0001] The utility model belongs to the technical field of power battery manufacturing, and specifically relates to a battery module assembly tool. Background Art

[0002] A battery module is a battery assembly consisting of single battery blocks or cells connected in series, parallel, or series-parallel. During the battery module manufacturing process, multiple battery blocks need to be placed side by side using tooling, and then the multiple side-by-side battery blocks are pressed together until the arranged battery blocks reach the specified precise size. Figure 1 As shown: the battery module includes a plurality of battery blocks 100 arranged side by side, and metal end plates 101 are arranged at both ends of a row of battery blocks 100, and then two straps 102 are used to tightly bind the side-by-side battery blocks and the metal end plates 101 at both ends together.

[0003] The existing battery module assembly tooling includes a module tray with a sliding design. During the assembly process, the battery block is first placed in the module tray, and then pushed to the clamping cylinder station. The side-by-side battery blocks are squeezed from both ends to the middle by the clamping cylinder, so that all the battery blocks are tightly together. Then, the strap is manually inserted from above the compressed battery block, and then the clamping force of the cylinder is withdrawn. The assembled battery module is removed from the tray and turned 180°, and then a strap is used to tighten the side-by-side battery blocks from the other end. The stability of the assembled battery module is achieved by the action of the upper and lower straps. Due to the shortcomings of the existing battery module assembly tooling design, when using the strap to tighten the battery block, the strap must be inserted from the upper and lower ends in steps, resulting in low assembly efficiency of the battery module. In addition, the assembled battery module has a large gravity. When it is manually taken out directly from the tray after assembly, it takes a lot of effort, resulting in high labor intensity for the operators. Based on this, there is an urgent need to develop a battery module assembly tool that can effectively solve the above-mentioned technical problems. Utility Model Content

[0011] Preferably, the regulator comprises a sliding rheostat connected in series in the electromagnet power circuit, and the sliding rheostat is provided with an insulating dial block for easy adjustment.

[0012] Beneficial effects: 1) When assembling a battery module, the assembly tool disclosed in the utility model can not only align the battery block laterally and press the two ends to the set size, but also, in the process of inserting the binding strap, first insert the binding strap from the upper end, then separate the module tray from the battery module by magnetic force, and then insert the binding strap from the lower end after separation, so as to realize the rapid installation of the upper and lower binding straps in the whole battery module assembly process, and improve the assembly efficiency of the whole battery module;

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings. Example 1

[0021] Reference Figure 2-Figure 5 , a battery module assembly tool, comprising a box seat 1, the upper surface of the box seat 1 is provided with two symmetrically arranged side panels 2, the side panels 2 are provided with guide slides 201, the rear end of the guide slide 201 is horizontally arranged, the front end is tilted downward, and the angle α between the front end and the rear end is an obtuse angle, the inner side of the side panel 2 is connected to the movable support bar 3 through two rollers 301, and the rollers 301 are arranged in the guide slide 201, the two movable support bars 3 are connected to the module tray 4 through guide rods 5, the guide rods 5 are provided with support springs 6, the bottom end of the guide rods 5 is provided with an anti-slip end block 501, and the lower surface of the module tray 4 is provided with an adsorption block 11;

[0022] Two mounting support plates 7 are symmetrically provided on the box seat 1 located on the outer sides of the two side panels 2, and a telescopic driving member 8 is provided on the upper part of the mounting support plate 7. The output ends of the two telescopic driving members 8 are both located between the two mounting support plates 7, and the output ends of the telescopic driving members 8 are connected to the clamping block 9 through the pushing plate 801. An electromagnet 10 that acts with an adsorption block 11 is provided on the upper surface of the box seat 1 located between the two mounting support plates 7. The electromagnet 10 is provided with a regulator 12 for adjusting the size of the current passed through it. Two vertical bars 14 are provided on the upper surface of the box seat 1 located behind the side panels 2. The two vertical bars 14 are connected by a baffle 15, and the baffle 15 is used to laterally align the battery blocks in the module tray 4.

[0023] A hand-holding portion 401 is provided on the side of the module tray 4 .

[0024] The telescopic driving member 8 is a cylinder, and the cylinder is controlled to start and stop by a switch button 13. The switch button 13 is arranged on the upper surface of the box seat 1, and the clamping block 9 is a rubber block.

[0025] The regulator 12 comprises a sliding rheostat connected in series in the energized circuit of the electromagnet 10, and the sliding rheostat is provided with an insulating block for easy adjustment.

[0026] When in use, first put multiple battery blocks 100 into the module tray 4, and place the metal end plates 101 on the left and right ends of the row of battery blocks 100. Then, the operator pushes the module tray 4 backward until the rear side of the battery block 100 contacts the stop bar 15 to achieve the horizontal alignment of a row of battery blocks 100, and then presses the switch button 13 to make the telescopic drive member 8 extend synchronously, and under the action of the two clamping blocks 9, the two metal end plates 101 are pushed toward the center, so that the side-by-side battery blocks 100 are pressed tightly together;

[0027] Then, the operator inserts the first binding strap 102 from the upper end to tighten the battery module from the upper end. After tightening, the current passed into the electromagnet 10 is increased through the regulator 12. At this time, the magnetic attraction of the electromagnet 10 to the adsorption block 11 increases, so that the module tray 4 moves downward to separate from the battery module. After separation, the operator inserts the second binding strap 102 from the lower end to tighten the battery module from the lower end. Then, the small current passed into the electromagnet 10 is restored or the electromagnet 10 is turned off. Under the action of the support spring 6, the module tray 4 moves upward again to insert the battery module. After the battery module is inserted into the module tray 4, the clamping effect is withdrawn;

[0028] Finally, the operator pulls the module tray 4 forward, so that the module tray 4 moves forward together with the battery module, and when the roller 301 at the front end moves to the front end inclined section of the guide slide 201, the entire module tray 4 and the battery module begin to tilt downward. At this time, the operator can easily remove the battery module from the module tray 4.

Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
