The technical solution of the present application is further described below by means of specific embodiments in conjunction with the accompanying drawings.

The embodiment of the application provides a cell spacing adjusting mechanism. Referring to fig. 1, the cell pitch adjustment mechanism 100 includes a first clamping assembly 110, a driving mechanism 120, a positioning jig assembly 130, and a manipulator 140. As shown in fig. 3, the first clamping assembly 110 includes a first clamping unit 111 and an adjusting member 112, and the first clamping unit 111 is used to clamp the battery cell 101. At least two first clamping units 111 are provided, and in the embodiment shown in fig. 3, two first clamping units 111 are provided, and one first clamping unit 111 clamps one cell 101. In other embodiments, the first clamping unit 111 may be other numbers, such as three or four, without limitation. The number of the first clamping units 111 can be specifically set according to the number of the electric cells 101 that need to be transferred at one time. The plurality of first clamping units 111 may be disposed in a plurality of positions on the first clamping assembly 110, and may be disposed in a single row as shown in fig. 3, or may be disposed in a plurality of rows, which is not limited herein.

As shown in fig. 3, the adjusting member 112 is connected to a part of the first clamping unit 111, and the adjusting member 112 can drive the first clamping unit 111 connected thereto to move, thereby adjusting the distance between the first clamping unit 111 and the adjacent first clamping unit 111. As shown in fig. 3, two first clamping units 111 are provided, an adjusting member 112 is connected to one of the first clamping units 111, and the adjusting member 112 pushes the first clamping unit 111 connected thereto to move relative to the other first clamping unit 111, so that the distance between the two first clamping units 111 can be adjusted. As described above, in other embodiments, there may be more than two first clamping units 111, and then the number of the adjusting members 112 may be specifically set according to the requirement, so as to meet the requirement of adjusting the distance between the first clamping units 111.

As shown in fig. 1 and 2, the driving mechanism 120 is connected to the first clamping assembly 110, and the driving mechanism 120 can drive the first clamping assembly 110 to move, so that the first clamping assembly 110 moves between different stations to clamp the battery cells 101 and place the battery cells 101. The positioning jig assembly 130 is used for placing the battery cells 101 with the spacing adjusted by the first clamping assembly 110. As shown in fig. 1, the positioning fixture assembly 130 is disposed below the first clamping assembly 110, so that the first clamping assembly 110 can place the battery cell 101 on the positioning fixture assembly 130.

As shown in fig. 1, the robot 140 is used to move the cell 101 on the positioning fixture assembly 130 to the next process. After the interval between the battery cells 101 is adjusted on the first clamping assembly 110, the battery cells 101 are placed on the positioning jig assembly 130, and then the manipulator 140 removes the battery cells 101 on the positioning jig assembly 130 and transfers the battery cells to the next process. For example, the first clamping assembly 110 takes the battery cells 101 on the battery cell conveying line, after the distance is adjusted, the battery cells 101 are placed on the positioning jig assembly 130, and then the mechanical arm 140 takes the battery cells 101 on the positioning jig assembly 130 and places the battery cells into a housing of the next process for assembly.

In this embodiment of the application, because the cell spacing adjustment mechanism 100 can clamp the cells 101 in the previous process and change the spacing between the cells 101, and then convey the cells to the next process, the cell spacing adjustment mechanism 100 can simultaneously convey a plurality of cells 101 backward at a time, and does not need to convey the cells 101 backward one by one in the same way in the traditional scheme, thereby improving the battery assembly efficiency.

As shown in fig. 3, in an embodiment, at least two first clamping units 111 are disposed along a first direction, and the adjusting member 112 can drive the first clamping units 111 connected thereto to move linearly along the first direction. For convenience of description, the first direction, the second direction, and the third direction are defined in the embodiments of the present application. The first direction, the second direction and the third direction are perpendicular to each other. As shown in fig. 1, the first direction, the second direction, and the third direction may correspond to an X direction, a Y direction, and a Z direction of the spatial coordinate system, respectively. The first direction, the second direction, and the third direction can also be understood as the front-rear direction, the left-right direction, and the up-down direction of the cell pitch adjustment mechanism 100. Referring to fig. 7, fig. 7 is a structural diagram of the cell transfer line 200. The cell transfer line 200 is located in the previous process of the cell pitch adjustment mechanism 100 of the present embodiment. As shown in fig. 7, the cells 101 on the cell transfer line 200 are transferred back along the first direction, that is, the cells 101 on the cell transfer line 200 are transferred back along the first direction next to each other, so, in the embodiment of the present application, as shown in fig. 3, at least two first clamping units 111 on the first clamping assembly 110 are disposed along the first direction, so that the first clamping assembly 110 can simultaneously clamp multiple cells 101 on the cell transfer line 200.

With continued reference to fig. 3, in an embodiment, the first clamping assembly 110 further includes an adapter plate 113. Referring to fig. 2 and 3, the adaptor plate 113 is connected to the driving mechanism 120, the adjusting member 112 is disposed at the top of the adaptor plate 113, the first clamping unit 111 is disposed at the bottom of the adaptor plate 113, and a part of the first clamping unit 111 passes through the adaptor plate 113 to be connected to the adjusting member 112. Part of the first clamping units 111 pass through the adapter plate 113 to be connected with the adjusting piece 112, that is, the first clamping units 111 which are required to be connected with the adjusting piece 112 pass through the adapter plate 113 to be connected with the adjusting piece 112, and the first clamping units 111 which are not required to be connected with the adjusting piece 112 are directly arranged at the bottom of the adapter plate 113 without passing through the adapter plate 113 to be connected with the adjusting piece 112. The adjusting piece 112 is arranged at the top of the adapter plate 113, the first clamping unit 111 is arranged at the bottom of the adapter plate 113, so that the adjusting piece 112 has enough installation space, and the adjusting piece 112 cannot interfere with the installation and movement of the first clamping unit 111, so that two adjacent first clamping units 111 can be close together to adapt to the cells 101 close together on the cell conveying line 200.

In one embodiment, as shown in fig. 3, the adjusting member 112 may be an air cylinder, and the first clamping unit 111 may be a pneumatic finger 1111. The air cylinder is adopted as the adjusting piece 112, so that the cost is low, and the requirement of changing the distance between the battery cell conveying line 200 and the battery cell 101 assembled by the battery shell can be met. The first clamping unit 111 has low cost due to the adoption of pneumatic fingers, and is convenient to install and clamp. As shown in fig. 3, the gripping direction of the first gripping unit 111 is along the second direction, that is, the two fingers 1111 of the pneumatic finger are oppositely disposed along the second direction. In this way, two adjacent pneumatic fingers (i.e., two adjacent first clamping units 111) can be brought into close proximity in the first direction without reserving an active space for the fingers 1111 in the first direction, thereby enabling the first clamping assembly 110 to clamp the cells 101 closely together on the cell conveyor line 200.

Referring to fig. 2, in an embodiment, the driving mechanism 120 may employ a three-dimensional moving module, and the three-dimensional moving module can drive the first clamping assembly 110 to move along the first direction, the second direction and the third direction. As shown in fig. 2, the three-dimensional moving module includes an X-direction moving module 121, a Y-direction moving module 122, and a Z-direction moving module 123, and the first clamping assembly 110 is connected to an output end of the Z-direction moving module 123. The movable modules in all directions can adopt linear driving modules such as linear motors, motor screw rod structures or sliding table cylinders. It will be appreciated that the driving mechanism 120 may also be configured by the manipulator 140, which is not limited herein. As shown in fig. 1 and 2, mounting frames 124 are disposed on the left and right sides of the equipment platform 102, and the three-dimensional moving module is mounted on the mounting frames 124, so that the three-dimensional moving module is lifted by the mounting frames 124, and the first clamping assembly 110 can move above the battery cells 101, thereby realizing the operation of clamping and placing the battery cells 101.

In this embodiment, the driving mechanism 120 adopts the three-dimensional moving module to enable the first clamping assembly 110 to move along the first direction, the second direction and the third direction under the driving of the three-dimensional moving module, and the first clamping assembly 110 moves along the first direction so that the first clamping assembly 110 can move between the previous process and the positioning jig assembly 130, that is, move between the battery cell conveying line 200 and the positioning jig assembly 130, and clamp and place the battery cells.

The first clamping assembly 110 is moved in the second direction such that the first clamping assembly 110 can accommodate different transport channels 201 on the cell transport line 200. Specifically, as shown in fig. 7, a plurality of conveying channels 201 are disposed on the battery cell conveying line 200 at intervals along the second direction, each conveying channel 201 can convey the battery cells 101 back along the first direction, and different conveying channels 201 are used for conveying the battery cells 101 with different capacitances. On the electric core transfer chain 200, different transfer channels 201 correspond to different electric capacity gears, before electric core transfer chain 200, divide the electric core 101 to hold, place electric core 101 of same electric capacity gear on same transfer channel 201 on electric core transfer chain 200, same electric capacity gear refers to electric capacity in same predetermined range. When the battery cell 101 is conveyed to the rear end of the battery cell conveying line 200, the first clamping assembly 110 clamps the battery cell 101 with the same capacitance gear and is placed in the same shell, and the battery cell 101 with the same capacitance is assembled into a battery, so that the performance of the battery can be better.

The linear moving module 131 can be installed on the equipment machine 102, the positioning jig 132 is connected with the linear moving module 131, and the linear moving module 131 can drive the positioning jig 132 to move along the first direction. Referring to fig. 1 and fig. 4, when the positioning jig 132 needs to be fed, the positioning jig 132 moves towards the first clamping assembly 110 along the first direction, moves to the lower side of the first clamping assembly 110, and the first clamping assembly 110 places the battery cell 101 on the positioning jig 132 to finish feeding; when the positioning jig 132 needs to be fed, the positioning jig 132 moves towards the manipulator 140 along the first direction, the manipulator 140 takes the battery cell 101 away from the positioning jig 132, feeding is completed, and the manipulator 140 then places the battery cell 101 taken away from the positioning jig 132 into a shell of the next process for assembly. In this embodiment, the positioning jig assembly 130 includes a linear moving module 131 and a positioning jig 132, so that the positioning jig 132 can move along a first direction, and the feeding level and the discharging level of the positioning jig 132 are staggered, and the discharging level is far away from the driving mechanism 120, thereby avoiding the driving mechanism 120 from interfering with the rotation of the manipulator 140.

With continued reference to fig. 4, two sets of positioning jig assemblies 130 may be disposed along the second direction, and when one positioning jig assembly 130 is blanking, the other positioning jig assembly 130 may be simultaneously fed, so as to improve the battery assembly efficiency.

Referring to fig. 5, in one embodiment, the positioning fixture 132 includes at least two positioning stations a, each for placing one of the cells 101. Therefore, the number of positioning stations a on the positioning jig 132 corresponds to the number of first clamping units 111 on the first clamping assembly 110, and if the first clamping assembly 110 has several first clamping units 111, several positioning stations a are disposed on the positioning jig 132.

Fixed locating plate 1321 is disposed on the other three sides of locating station a. The movable positioning plate 1322 can move in the second direction to approach or separate from the fixed positioning plate 1321.

After the cell 101 is placed on the positioning station a, the movable positioning plate 1322 moves rightward, and the cell 101 is pressed against the fixed positioning plate 1321, so that the cell 101 is positioned. The manipulator 140 removes the positioned cell 101.

The movable positioning plate 1322 is connected to a driving member 1323, and the driving member 1323 can drive the movable positioning plate 1322 to move along the second direction.
