The two carrier boards 111 can be installed on the rack 110 through guide rails and slide blocks, and can slide along the first direction.
电芯定位组件120能够沿第一方向及第二方向对承载于载板111的电芯20进行定位。具体的,电芯定位组件120设置有两组,且分别用于对两个载板111上的电芯20进行定位,两组电芯定位组件120的结构可以完全相同。The battery core positioning component 120 can position the battery core 20 carried on the carrier board 111 along the first direction and the second direction. Specifically, two groups of battery core positioning assemblies 120 are provided, and they are respectively used to position the battery cores 20 on the two carrier boards 111. The structures of the two groups of battery core positioning assemblies 120 can be exactly the same.

The number of adapter sheet positioning components 130 is consistent with the number of placement blocks 112. Specifically, in this embodiment, there are two adapter sheet positioning components 130.
定位驱动组件131驱使定位板132沿第二方向抵持转接片21,便可对转接片21在第二方向上进行定位。如此,两个电芯20及其转接片21将在定位机构100上实现第一方向及第二方向的定位。The positioning driving assembly 131 drives the positioning plate 132 to resist the adapter piece 21 in the second direction, so that the adapter piece 21 can be positioned in the second direction. In this way, the two battery cores 20 and their adapter pieces 21 will be positioned in the first direction and the second direction on the positioning mechanism 100 .
请一并参阅图5及图6,在本实施例中,每个定位板132朝向放置块112的一侧形成有突出部1321,定位驱动组件131能够带动定位板132下降,以使突出部1321将转接片21压持于放置块112。Please refer to FIGS. 5 and 6 together. In this embodiment, each positioning plate 132 is formed with a protruding portion 1321 on one side facing the placement block 112 .

具体的,定位驱动组件131能够带动定位板132沿第三方向移动,第三方垂直于第一方向及第二方向,也即图4所示垂直于图纸平面的方向。当转接片21在定位过程中发生翘起时,定位驱动组件131可驱动定位板132下降从而使突出部1321按压在转接片21表面以将其压平。如此,定位驱动组件131还可对转接片21在第三方向上进行定位。Specifically, the positioning drive assembly 131 can drive the positioning plate 132 to move in a third direction, which is perpendicular to the first direction and the second direction, that is, the direction perpendicular to the drawing plane as shown in FIG. 4 . When the adapter piece 21 is tilted during the positioning process, the positioning drive assembly 131 can drive the positioning plate 132 to descend so that the protruding portion 1321 presses the surface of the adapter piece 21 to flatten it. In this way, the positioning driving assembly 131 can also position the adapter piece 21 in the third direction.
进一步的,在本实施例中,限位件1121为沿第二方向延伸的凸条,突出部1321上开设
有避位槽1322,突出部1321将转接片21压持于放置块112时,凸条穿过所述避位槽1322。凸条与转接片21的接触面积更大,故对于转接片21限位效果更好。而避位槽1322则能防止限位件1121对突出部1321在下降过程中造成限位,从而使得突出部1321能够将转接片21压紧于放置块112的表面。Further, in this embodiment, the limiting member 1121 is a convex strip extending along the second direction, and the protruding portion 1321 is provided with There is an escape groove 1322. When the protruding portion 1321 presses the adapter piece 21 to the placement block 112, the protruding strip passes through the escape groove 1322. The contact area between the protrusions and the adapter piece 21 is larger, so the limiting effect on the adapter piece 21 is better. The avoidance groove 1322 can prevent the limiting member 1121 from limiting the protruding portion 1321 during the descending process, so that the protruding portion 1321 can press the adapter piece 21 against the surface of the placing block 112 .

Pairing means that the poles on the top cover are respectively inserted into the connection holes 22 of the adapter sheets 21 of the two battery cells 20 . When the transport mechanism transfers the battery cells 20, the relative positions of the two battery cells 20 and their adapter pieces 21 remain unchanged, so the two battery cells 20 can be paired with the top cover on the pairing mechanism at the same time.
而且,焊接定位装置一般还包括焊接机构(图未示),在两个电芯20与顶盖配对完成后,由焊接机构将转接片21与顶盖进行焊接。Moreover, the welding positioning device generally also includes a welding mechanism (not shown). After the two battery cores 20 are paired with the top cover, the welding mechanism welds the adapter piece 21 to the top cover.
在本实施例中,配对机构上设置有限位组件(图未示),限位组件用于对搬运机构200搬运至配对机构的两个电芯20及电芯20的转接片21进行限位。当搬运机构200将定位好的两个电芯20搬运至配对机构上时,先由限位组件对两个电芯20及其转接片21的位置进行固定;限位组件固定完成后,搬运机构200再释放电芯20及其转接片21,故可避免两个电芯20的相对位置在转移过程中发生变化,从而确保电芯20与顶盖顺利实现配对。In this embodiment, a limiting component (not shown) is provided on the pairing mechanism. The limiting component is used to limit the two battery cells 20 and the adapter piece 21 of the battery core 20 that are transported to the pairing mechanism by the transport mechanism 200 . . When the transport mechanism 200 transports the two positioned electric cores 20 to the pairing mechanism, the position of the two electric cores 20 and its adapter piece 21 is first fixed by the limiting component; after the fixing of the limiting component is completed, the transportation The mechanism 200 then releases the battery core 20 and its adapter piece 21, thereby preventing the relative positions of the two battery cores 20 from changing during the transfer process, thus ensuring smooth pairing of the battery core 20 and the top cover.

The relative positions of the clamping member 210 and the holding assembly 220 remain fixed, and both can be fixedly installed on the bracket 230 of the transport mechanism 200 . When the battery core 20 is clamped by the clamping member 210, the holding assembly 220 fixes the adapter piece 21, so that the adapter piece 21 can be prevented from moving relative to the battery core 20 during transportation, thereby ensuring smooth connection with the top cover. pair.

每一组吸盘221可设置一个,也可设置多个;每一组定位针222的数量与每个转接片21上连接孔22的数量一致。譬如,本实施例中转接片21上开设有两个连接孔22,故每一组定位针222设置有两个。而且,定位针222的数量及分布与顶盖上极柱的数量及分布相同。
Each group of suction cups 221 can be provided with one or more; the number of positioning pins 222 of each group is consistent with the number of connecting holes 22 on each adapter piece 21 . For example, in this embodiment, the adapter piece 21 is provided with two connection holes 22 , so each group of positioning pins 222 is provided with two. Moreover, the number and distribution of the positioning pins 222 are the same as the number and distribution of the poles on the top cover.
定位针222的末端呈圆台形,能够起到导向作用,从而方便定位针222顺利插入连接孔22。搬运机构200在从定位机构100夹取电芯20时,两个夹取件210下降并分别夹取两个电芯20,同时保持组件220下降至两个转接片21表面,并使定位针222分别插入对应的连接孔22中且吸盘221吸附转接片21;搬运机构200在将所夹取的两个电芯20放置于配对机构时,先下降并使定位针222与顶盖上的极柱相抵持,便可使连接孔22与极柱实现对位,再释放两个电芯20,便可使顶盖的极柱插入对应的连接孔22内,从而最终顺利完成配对。The end of the positioning pin 222 is in the shape of a truncated cone, which can serve as a guide, thereby facilitating the smooth insertion of the positioning pin 222 into the connecting hole 22 . When the transport mechanism 200 clamps the electric cores 20 from the positioning mechanism 100, the two clamping members 210 descend and clamp the two electric cores 20 respectively. At the same time, the holding assembly 220 lowers to the surface of the two adapter sheets 21 and moves the positioning pins. 222 are inserted into the corresponding connection holes 22 respectively, and the suction cup 221 absorbs the adapter piece 21; when placing the two clamped batteries 20 in the pairing mechanism, the transport mechanism 200 first lowers and aligns the positioning pin 222 with the one on the top cover. When the poles are against each other, the connection holes 22 and the poles can be aligned, and then the two batteries 20 are released, so that the poles of the top cover can be inserted into the corresponding connection holes 22, thereby successfully completing the pairing.
上述定位机构100及焊接定位装置,先将待定位的两个电芯20分别放置于两个载板111,并使其转接片21承载于放置块112上。电芯定位组件120对电芯20沿第一方向及第二方向进行定位,并在定位完成后由载板111带动两个电芯20沿第一方向相互靠近,直至两个电芯20的转接片21与限位件1121相抵持。接着,定位驱动组件131驱使定位板132沿第二方向抵持转接片21,可对转接片21在第二方向上进行定位。如此,两个电芯20及其转接片21将在定位机构100上实现定位,再通过搬运机构200将定位后的两个电芯20整体搬运至配对机构与顶盖配对即可。因此,上述定位机构100及焊接定位装置能够提升生产效率。The above-mentioned positioning mechanism 100 and welding positioning device first place the two battery cores 20 to be positioned on the two carrier plates 111 respectively, and have the adapter piece 21 carried on the placement block 112 . The battery core positioning assembly 120 positions the battery core 20 along the first direction and the second direction, and after the positioning is completed, the carrier plate 111 drives the two battery cores 20 to approach each other along the first direction until the two battery cores 20 rotate. The connecting piece 21 resists the limiting member 1121 . Then, the positioning driving assembly 131 drives the positioning plate 132 to resist the adapter piece 21 in the second direction, so that the adapter piece 21 can be positioned in the second direction. In this way, the two battery cores 20 and their adapter sheets 21 will be positioned on the positioning mechanism 100, and then the two positioned battery cores 20 will be transported as a whole to the pairing mechanism through the transport mechanism 200 for pairing with the top cover. Therefore, the above-mentioned positioning mechanism 100 and welding positioning device can improve production efficiency.
