The battery picking and placing device 10 includes a first connector 11 extending along a first direction (taking an X axis in fig. 1 and 2 as a first direction), a second connector 12 extending along the first direction, and the second connector 12 is movably spaced from the first connector 11 along a second direction (taking a Y axis in fig. 1 and 2 as a second direction). The battery pick-and-place device 10 further includes two elastic members 13 disposed at intervals in the first direction, two transmission units disposed at intervals in the first direction, and two clamping members 16 disposed at intervals in the first direction. The elastic member 13 is sandwiched between the first connecting member 11 and the second connecting member 12, and two ends of the elastic member 13 are respectively connected with the first connecting member 11 and the second connecting member 12. The transmission unit comprises a first transmission piece 14 and a second transmission piece 15 which are arranged on the same side of the battery taking and placing device 10; one end of the first transmission member 14 is rotatably connected to one end of the first connection member 11, one end of the second transmission member 15 is rotatably connected to one end of the second connection member 12, and the other end of the second transmission member 15 is rotatably connected to the first transmission member 14. Each of the holding members 16 is rotatably provided at the other end of the corresponding side first transmission member 14. Wherein the gap between the two clamping members 16 constitutes a clamping gap 19 for clamping the battery 30. It will be appreciated that the pre-compression force of the resilient member 13 is able to ensure that the two clamping members 16 are in an open condition (i.e. have a clamping gap 19).

In this way, the operator applies an external force to move the second connecting member 12 in the second direction toward the first connecting member 11, so that the elastic member 13 disposed between the first connecting member 11 and the second connecting member 12 is compressed, and the second connecting member 12 drives the two transmission units rotatably connected therewith to move toward each other, thereby driving the two clamping members 16 to also move toward each other, and the force applied by the operator's hand can clamp the square-case battery disposed in the clamping gap 19. The battery taking and placing device 10 is simple to operate, is suitable for taking and placing the battery in a narrow space, is beneficial to improving the production efficiency of the square-shell battery, and also avoids pollution to the square-shell battery caused by direct manual taking and placing of the square-shell battery by an operator.

The first transmission members 14 are bending members, and along the direction in which the first connection member 11 points to the second connection member 12, the two first transmission members 14 are respectively extended in a direction away from each other, and then are folded in a direction close to each other. The second transmission member 15 is rotatably connected to a bending portion of the first transmission member 14, where the bending portion refers to a position where the two first transmission members 14 are spaced most apart along the first direction. Therefore, the first transmission piece 14 is arranged to be the bending piece, so that the connection position of the first transmission piece 14 and the second transmission piece 15 is facilitated to be determined, the installation accuracy is improved, and meanwhile, the second transmission piece 15 is facilitated to drive the first transmission piece 14 to move along the second direction towards the direction close to the other first transmission piece 14, and the square-shell battery is facilitated to be clamped.

In this way, by providing the guide member 17 to guide the elastic member 13, the elastic member 13 can be compressed along the extending direction (i.e., the second direction) of the guide member 17 when compressed, so that the elastic member 13 can be prevented from being distorted when compressed to affect the taking and placing of the battery pack by the clamping member 16.

In some embodiments, the guide member 17 is a guide pin, and the guide pin has the characteristics of stable support and high wear resistance, can stably support the second connecting member 12, and has little wear after the second connecting member 12 reciprocates in the second direction. Of course, the guide 17 may be a guide rod, a slide rail, a screw, or the like.

In some embodiments, the second connecting member 12 is provided with two guide holes (not shown) at intervals along the first direction, wherein one guide member 17 passes through the second connecting member 12 by means of one of the guide holes, and the other guide member 17 passes through the second connecting member 12 by means of the other guide hole.

In some embodiments, the guide hole has a larger diameter than the outer diameter of the guide 17. In this way, the guide 17 is easily installed, saving time.

It will be appreciated that in order to facilitate the smooth and rapid passage of the guide 17 through the guide aperture, the aperture of the guide aperture is made larger than the outer diameter of the guide 17. Meanwhile, in order to fix the guide 17, one end of the guide 17 near the first link 11 in the second direction may be fixed to the first link 11 by a fastener, which may be a screw or the like.

In some embodiments, with continued reference to fig. 1 and 2, the clamp 16 includes a clamp body 161 and a ram 162. The clamping body 161 is rotatably provided at the other end of the first transmission member 14 of one of the transmission units. The pressure head 162 is arranged on one side of the clamping main body 161 facing the other clamping piece 16, and one side of the pressure head 162 facing away from the clamping main body 161 is used for clamping the square-shell battery.

In some embodiments, the ram 162 is a rubber ram, which is highly elastic and soft and does not scratch the surface of the battery 30 when held. Of course, the ram 162 may be made of other soft materials, such as silicone, soft thermoplastic elastomer, thermoplastic polyurethane, plastic soft rubber material, etc.

In this way, by setting the ram 162 to be a rubber ram, the ram 162 can be prevented from scratching the square-case battery when clamping the square-case battery.

In some embodiments, with continued reference to fig. 1 and 2, the clamp 16 includes two spaced apart rams 162. Thus, when clamping the square battery, the operator can control the pressing force of the elastic member 13 by controlling the magnitude of the applied external force, thereby adjusting the positions of the pressing heads 162, so that the side surfaces of the two pressing heads 162 facing each other are automatically attached to the outer side surface of the square battery and clamp the square battery, and the square battery is ensured to be clamped stably.

It will be appreciated that the number of rams 162 may be adjusted according to the size of the clamping body 161, the more rams 162, the more smoothly the square-case battery is clamped.

In some embodiments, with continued reference to fig. 2, the clamping body 161 is provided with a limiting aperture 1611 for limiting the amplitude of oscillation of the clamping body 161 in a direction toward or away from the other clamping member 16 during rotation. Specifically, the limiting hole 1611 is a rectangular through hole, so that the clamping body 161 has an upper edge and a lower edge on a side close to the corresponding first transmission member 14, and the upper edge and the lower edge are correspondingly arranged along the second direction; the first transmission member 14 partially extends into the limiting hole 1611 to be connected with the clamping body 161, so that in the swinging process of the clamping body 161, the upper edge and the lower edge of the clamping body 161 collide with the first transmission member 14, thereby limiting the swinging amplitude of the clamping body 161.
