The embodiment of the application provides a positioning mechanism, which can realize centering and positioning of a battery cell 700, so that a manipulator of a carrying mechanism can accurately grasp the battery cell 700. Specifically, the positioning mechanism includes a base 100, a spacer 200 and two centering assemblies 300, as shown in fig. 1, the spacer 200 is disposed on the base 100, and by disposing the spacer 200 to support the battery cell 700, compared with a contact area where the battery cell 700 is directly disposed on the base 100, the resistance of the battery cell 700 when moving relative to the spacer 200 is smaller. The two centering components 300 are respectively arranged at two sides of the cushion block 200 along the first direction, after the battery cell 700 is placed on the cushion block 200, the two centering components 300 are respectively positioned at two sides of the battery cell 700, the distances between the two centering components 300 and the cushion block 200 are equal, the first pushing pieces 310 of the two centering components 300 can move in opposite directions, and if the center line of the battery cell 700 is offset from the center line of the cushion block 200, the first pushing pieces 310 of the centering components 300 are abutted with the battery cell 700 and push the battery cell 700 to move until the center line of the battery cell 700 coincides with the center line of the cushion block 200.

Specifically, each centering assembly 300 includes a first pushing member 310 and a limiting member 320, where the first pushing member 310 is disposed on the base 100 and is capable of sliding relative to the base 100, as shown in fig. 1 to 4. After the battery cell 700 is placed on the cushion block 200, the two first pushing members 310 can move in opposite directions along the first direction until the two first pushing members 310 respectively abut against the two side walls of the battery cell 700. The two first pushing members 310 ensure that the moving distances of the two first pushing members are equal in the moving process, so that the battery cell 700 can be kept at the middle position.

The limiting member 320 is connected to the first pushing member 310, as in the embodiment shown in fig. 1 to 4, the limiting member 320 is disposed on the top surface of the sliding guiding portion 312 of the first pushing member 310, and in other embodiments, the limiting member 320 may be disposed on a side surface of the sliding guiding portion 312 of the first pushing member 310 or disposed on the abutting portion 311 of the first pushing member 310. When the first pusher 310 moves, the stopper 320 moves in synchronization with the first pusher 310. As shown in fig. 1 and 2, the first fixing member 110 is disposed on the moving path of the first pushing member 310, and in the moving process of the first pushing member 310 approaching to the cushion block 200, the distance between the limiting member 320 and the first fixing member 110 is gradually shortened until the limiting member 320 abuts against the first fixing member 110, so that the further movement of the first pushing member 310 is limited to avoid the cell 700 from being damaged by the clamping.

Based on the above, the embodiment of the application realizes the centering of the battery cell 700 through the two centering assemblies 300, so that the clamping position of the mechanical claw of the conveying mechanism can be designed by taking the center line of the cushion block 200 as a reference, and further, the clamping with high precision can be realized. In addition, since there may be a gear gap in the driving mechanism of the first pushing member 310, when the two first pushing members 310 drive the battery cells 700 to be centered, it cannot be effectively ensured that the center line of each time the battery cells 700 coincides with the center line of the spacer 200, and there may be a centering deviation between the battery cells 700 in different batches of centering. Therefore, the limiting member 320 can realize the hard limiting of the first pushing member 310 during the centering process, ensure the uniformity of centering of each cell 700 when two first pushing members 310 are centered, and prevent the first pushing member 310 from damaging the cell 700 during the centering process.

In some embodiments, each first pushing member 310 includes an abutment portion 311 and a sliding guide portion 312, and as shown in fig. 3, the abutment portion 311 and the sliding guide portion 312 have an L-shaped structure. Specifically, the abutment portion 311 extends upward perpendicular to the top surface of the base 100 until the height of the abutment portion 311 is higher than the height of the pad 200, so that the abutment portion 311 can abut against the side wall of the battery cell 700. The guide sliding part 312 is parallel to the base 100 and extends towards the direction of the cushion block 200, the first fixing piece 110 is provided with a through groove, the guide sliding part 312 is penetrated in the through groove, and the first fixing piece 110 can guide the movement of the first pushing piece 310 to prevent the movement from deviating so as to cause larger error in centering of the battery cell 700. The limiting member 320 is disposed on the sliding guide portion 312 and can move along with the movement of the first pushing member 310, and when the abutment portions 311 of the first pushing members 310 on both sides are in abutment with the battery cell 700, the limiting member 320 abuts against the first fixing member 110, so that the battery cell 700 is kept at the centered position.

Further, the heights of the first fixing element 110, the sliding guiding portion 312 and the limiting element 320 are smaller than the height of the spacer 200, and it should be noted that, as shown in fig. 3, the limiting element 320 is disposed on the sliding guiding portion 312, and at this time, the height of the top end of the limiting element 320 is still smaller than the height of the spacer 200, so as to avoid interference when the battery cell 700 is placed on the spacer 200. When the battery cell 700 is placed on the cushion block 200, a gap is formed between the bottom surface of the battery cell 700 and the top surface of the base 100, and the first fixing element 110, the sliding guide part 312 and the limiting element 320 are all located in the gap, so that the gap between the battery cell 700 and the base 100 is fully utilized for arrangement of parts, and the space utilization rate is improved.

The mounting portion 220 is detachably connected with the base 100, and the mounting portion 220 is provided with a containing groove for containing the sliding guide portion 312 to pass through, so that the sliding guide portion 312 can be inserted into the containing groove in the process of moving the first pushing member 310 in opposite directions, and the sliding guide portion 312 is prevented from abutting against the cushion block 200. It can be appreciated that the accommodating groove may be a through groove penetrating along the first direction, and the first pushing members 310 on both sides may be inserted into the accommodating groove recess or may be a non-penetrating groove.

In some embodiments, the limiting member 320 includes a buffer 321, where the buffer 321 is configured to abut against the first fixing member 110, and is capable of eliminating vibration and impact caused by a moving collision of the buffer 321 when abutting against the first fixing member 110, so as to avoid damage caused by a rigid collision between the limiting member 320 and the first fixing member 110. In addition, the limiting member 320 further includes a first mounting seat 322, and the buffer 321 is disposed through the first mounting seat 322 along a first direction, as shown in fig. 3, on a side of the first mounting seat 322 near the first fixing member 110, the buffer 321 protrudes from the first mounting seat 322, and the length of the buffer 321 protruding from the first mounting seat 322 can be adjusted to be adapted to the centering of the battery cells 700 with different sizes. Further, the position of the first mounting seat 322 on the slide guide 312 can also be adjusted so as to be able to adapt to the centering of the battery cells 700 of a larger size range.

In some embodiments, the positioning mechanism includes a first driving member 400, where the first driving member 400 is connected to the base 100 and is connected to two first pushing members 310, respectively. It should be noted that the first driving member 400 can simultaneously drive the two first pushing members 310 disposed opposite to each other to move toward each other. As shown in fig. 1 and 3, two centering stations are provided on the base 100, so that centering of two battery cells 700 can be achieved simultaneously. For this purpose, four centering assemblies 300 are disposed on the base 100, the centering assemblies 300 are grouped in pairs, and two centering assemblies 300 of the same group are disposed on two sides of the pad 200 along the first direction. The first driving member 400 can drive the first pushing members 310 of the two centering assemblies 300 of the same group, so that the two first pushing members 310 synchronously move towards each other to push the battery cells 700 to be centered.

In some embodiments, the positioning mechanism further includes a second fixing member 500 and a pressing assembly 600, as shown in fig. 1 to 4, the pressing assembly 600 can abut against a bottom surface (relative to the top cover 710) of the battery cell 700, so that the top cover 710 abuts against the second fixing member 500, thereby achieving positioning based on the top cover 710. Specifically, the pressing assembly 600 and the second fixing member 500 are disposed at both sides of the pad 200 along the second direction, respectively, and the first direction and the second direction are perpendicular to each other. The pressing assembly 600 includes a second driving member 610 and a second pushing member 620, where the second driving member 610 can drive the second pushing member 620 to move along a second direction so as to push the battery cell 700 to abut against the second fixing member 500.
