When the battery module is placed between the first reference member 21 and the first clamping member 22 and between the second reference member 31 and the second clamping member 32, the first clamping member 22 first moves toward the side close to the first reference member 21 in the X-axis direction, thereby first achieving clamping positioning in the X-axis direction of the battery module. And there is a frictional force between the battery module and the support 4 since the battery module is placed on the support 4 while the battery module is moved in a direction to approach the first reference member 21. The battery module moves while driving the supporting member 4 to move together, the supporting member 4 moves towards the direction close to the first reference member 21, and the position between the supporting member 4 and the battery module is not changed.

When the connection assembly 41 is pushed by an external force to move in a direction approaching the second reference member 31, the first guide shaft 421 on the connection assembly 41 moves along the axial direction of the first through hole. At this time, the distance between the connection assembly 41 and the second reference member 31 is gradually reduced, the spring is compressed, and the spring stores elastic potential energy due to its own deformation.

When the clamping block structure 222 is pushed by an external force to move in a direction approaching the first reference member 21, the third guide shaft 2221 on the clamping block structure 222 moves along the axial direction of the third through hole. At this time, the distance between the clamping block structure 222 and the first reference member 21 is gradually reduced, the spring is compressed, and the spring stores elastic potential energy due to self-deformation.

The guide rail structure is arranged along the Y-axis direction, and the slider structure can slide along the length direction of the guide rail structure to realize the guiding of the sixth connecting piece 7 when moving relative to the supporting structure 1. The guide of the sixth connecting piece 7 during movement can be realized through the slider structure and the guide rail structure, so that the sixth connecting piece 7 can only move along the Y-axis direction.

As shown in fig. 1, a spacer 9 may be mounted on the sixth connecting member 7 at an end close to the battery module, and the spacer 9 may be replaced according to the size of the battery module. When the length of the battery module in the Y-axis direction is short, a cushion block 9 with a long length can be arranged on the sixth connecting piece 7, so that the clamping force of the battery module in the Y-axis direction can be guaranteed; when the length of the Y-axis direction of the battery module is longer, the cushion block 9 with shorter length can be arranged on the sixth connecting piece 7 so as to ensure the clamping force when the Y-axis direction of the battery module is clamped. The cushion block 9 and the sixth connecting piece 7 can be connected through bolts, and users can replace the cushion block 9 with different sizes according to actual processing requirements.

As shown in fig. 1, the positioning apparatus further includes a third driving mechanism 8, the third driving mechanism 8 is mounted on the supporting structure 1, the third driving mechanism 8 is in driving connection with the supporting member 4, and the third driving mechanism 8 is adapted to drive the supporting member 4 to move toward or away from the first positioning assembly 2.

The third driving mechanism 8 may be a cylinder, an electric cylinder, a stepping motor, a servo motor, a linear motor, etc. Taking the cylinder as an example, the cylinder may be a double-acting cylinder, the cylinder may be provided with two air holes, and the air flows through the two air holes, so that the piston rod may move along the positive direction and the negative direction of the Z axis. From this, can realize support piece 4 along the removal of Z axle direction through double-acting cylinder to the realization carries out the adaptation to the battery module Z of unidimensional not, ensures the tight location effect of clamp of battery module.

For example, to the longer battery module of Z axle direction size, remove along Z axle negative direction through 8 drive support piece 4 of third actuating mechanism, can avoid because battery module size is longer, battery module protrusion positioner is unfavorable for subsequent laser beam machining. Secondly, to the shorter battery module of Z axle direction size, drive support piece 4 through third actuating mechanism 8 and remove along Z axle positive direction, can be so that the battery module is arranged in first locating component 2 and second locating component 3, be convenient for to the tight location of clamp of battery module.

Although the present application has been disclosed above, the scope of protection of the present application is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and such changes and modifications will fall within the scope of the present invention.
