Description

Technical Field

[0001] The invention relates to the field of battery core transmission, in particular to a multi-station loading device. Background Art

[0002] During the production process of battery cells, the battery cells need to be charged and tested after charging.

[0003] During the entire process, battery cells are charged in batches. In the current production process, battery cells are placed in batches into a fixture, which constrains the position of each battery cell, simplifying the positioning steps of subsequent charging and testing.

[0004] The current loading equipment uses single-station batch loading, which places multiple unidirectional battery cells (the battery cells have tabs and a specific arrangement direction) directly into the fixture.

[0005] As we all know, the single-station design has the problem of low efficiency. When it comes to improving efficiency, the double-station design is the most effective and common design idea. However, the current fixture positions the battery cell by relying on the clamping function. The clamps that realize this clamping function are all facing the same direction. Considering that the mechanism for opening the clamp is integrated into the entire transfer mechanism, the conventional method of adding stations will make the round-trip path of the mechanism more complicated. Obviously, this is not suitable for the current loading method.

[0006] In order to meet the needs of multiple stations, the current stage adopts the premise of replacing the fixture and redesigning the loading device. The change of the fixture is more of a change in layout.

[0047] The first clamping part 12 and the second clamping part 11 are designed as double-stations. The rotating mechanism 10 can change the position of the battery cell and change the direction of the tabs on the battery cell 4. Therefore, after the battery cell 4 is turned over and flattened by the turning mechanism 1, the tabs on the battery cell 4 are facing away from the clamping part, so that the tabs will not be clamped by the clamping part.

[0048] The flattening mechanism 2 includes a first platform part 20, a pressing plate 21, and a lifting mechanism 23. The middle area of ​​the first platform part 20 is an open structure. The pressing plates 21 are provided with a plurality of pressing plates. The pressing plates 21 are located in the open structure.

Under the action of the telescopic mechanism, the pressing portion 21a can fall into the first positioning groove 20a in different directions to flatten the pole ear in the first positioning groove 20a, thereby realizing the pressing of the pole ear on the symmetrically arranged battery cell 4.

[0050] The row spacing adjustment mechanism 3 includes a second table portion 31 carrying the battery clamp 5, wherein the row spacing adjustment mechanism 3 includes a workbench 32 and a third movable plate 34 and a positioning plate 33 arranged on the workbench 32, the third movable plate 34 is arranged on the positioning plate 33, and at the same time, the third movable plate 34 has an end portion extending to the surface of the workbench 32, and the end portion is slidably connected to the workbench 32, and a positioning area for constraining the battery cell 4 is formed between a positioning protrusion 33a provided on the positioning plate 33 and a side surface of the third movable plate 34, and in the above-mentioned positioning area, there are a plurality of movable positioning components 36, which divide the above-mentioned positioning area into a plurality of clamping positions;

[0051] The positioning device is pre-equipped with multiple positioning positions for the battery cells 4. The positioning protrusion 33a and the third movable plate 34 apply pressure to the side of the battery cell 4 along the length direction, so that the position of the battery cell 4 is adjusted to a predetermined position and direction. The positioning component 36 applies pressure to the side of the battery cell 4 along the width in the positioning area, and finally multiple battery cells 4 are positioned at the predetermined positions. Combined with the transfer mechanism 6, the battery cell 4 that has been positioned is placed on the battery cell fixture 5, thereby achieving positioning of multiple battery cells 4 that are adjacent to each other at a close distance.

[0052] The transfer mechanism 6 is used to extract the battery cell 4 from the row spacing adjustment mechanism 3 to the battery cell fixture 5. The transfer mechanism 6 includes a third linear moving component 601, an adsorption component, and a contact release component for opening the clamping member 51. The adsorption component and the contact release component are connected to the output end of the linear moving component. The adsorption component is provided in a group and is respectively located outside the two sides of the contact release component.

[0053] The transfer mechanism 6 is a double-station design. By placing two battery cells 4 in different orientations on the battery cell fixture 5, a double-station loading effect is achieved. At the same time, in the transfer mechanism 6, the adsorption components are located outside the two sides of the same contact release component. Therefore, the loading process is optimized and the production capacity is faster.

There are multiple suction cups 14, which are connected to multiple output ends of the driving assembly, and the suction cup 14 corresponds to the above-mentioned pressing groove 15a. The purpose of adopting the above-mentioned technical scheme is to allow the battery cell 4 to be sucked by the suction cup 14. Since the battery cell 4 will undergo multiple transfers during the production process, some of the battery cells 4 will have certain deformation, and the battery cell 4 will be uneven. At this time, the inner side of the pressing groove 15a provides a supporting effect. Combined with the pneumatic fingers, the battery cell 4 in a vertical state is flattened in a clamping posture to ensure that the battery cell 4 can be sucked by the suction cup 14.

[0059] Furthermore, a variable pitch module is provided at the output end of the first linear motion mechanism 1000, and the variable pitch module includes a second driving cylinder 1001, a main board 1002, and a plurality of groups of scissor struts 1003 and a fixed seat 1004. The fixed seats 1004 are separated from each other, and the fixed seat 1004 is slidably connected to the surface of the main board 1002.

Specifically, the first adjusting screw 60f on the first positioning slider 60e is threadedly connected to the second positioning slider 60g, and the first adjusting screw 60f does not penetrate the second positioning slider 60g. Similarly, the second positioning slider 60g, the third positioning slider 60h, and the fourth positioning slider 60i are also arranged in the same way. The output end of the adsorption cylinder 60b is connected to the first positioning slider 60e on the edge. When the adsorption cylinder 60b pulls the first positioning slider 60e to move toward the center position of the side of the mounting plate 60a, the first adjusting screw 60f first rotates and moves into the threaded hole on the second positioning slider 60g to shorten the distance between the first adjusting screw 60f and the second positioning slider 60g. When the first adjusting screw 60f reaches the end of the threaded hole of the second positioning slider 60g, the first adjusting screw 60f pushes the second positioning slider 60g in the form of advancement, so that the second adjusting screw 60j on the second positioning slider 60g moves into the third positioning slider 60h in the same form. The remaining positioning sliders also move according to the same principle, so they will not be described in detail.
