[0033] Referring to Figures 1 to 7 As shown in the figure, according to the battery pack conveying device provided by the embodiment of the application, it comprises a rack 100, a supporting assembly 200 and a transmission assembly 300, the rack 100 is composed of a mounting frame 110 and a supporting frame 120. Optionally, the mounting frame 110 and the supporting frame 120 are both frame structures formed by welding rigid strength structural steel. The mounting frame 110 is arranged obliquely, the supporting frame 120 is welded and fixed with the mounting frame 110 to support the mounting frame 110, and the mounting frame 110 has a positioning surface 111 arranged at an angle with the horizontal plane.

[0034] The supporting assembly 200 is installed on the positioning surface 111 and can be in rolling friction cooperation with the battery pack to be assembled. Optionally, the supporting assembly 200 can be set as a roller rotatably installed at the positioning surface 111, a steel ball inlaid at the positioning surface 111 or other rolling components, which will not be described here.

Optionally, the transmission assembly 300 can be provided as a transmission belt, a linear module, a transmission jig, etc., which will not be described here. The transmission assembly 300 is used to transport the battery pack, and the transmission assembly 300 has a transmission surface perpendicular to the positioning surface 111, i.e., the plane where the part of the transmission assembly 300 in contact with the battery pack is located, such as the top surface of the belt, the top surface of the sliding table of the linear module, the positioning surface 111 of the jig, etc. It is particularly noted here to avoid misunderstanding. The transmission surface is in contact with the side wall of the battery pack to make the battery pack parallel to the positioning surface 111.

[0036] It can be understood that by providing the support assembly 200 and the transmission assembly 300, the side wall of the battery pack is in contact with the transmission surface of the transmission assembly 300, at this time, the battery pack is parallel to the positioning surface 111 and abuts against the support assembly 200, and when the transmission assembly 300 transports the battery pack, the support assembly 200 supports the battery pack and is in rolling frictional engagement with the battery pack, thereby stably transporting the battery pack in an inclined posture to the rack 100, reducing the horizontal distance of the two sides of the battery pack, enabling a single user to complete the wiring work on the two sides of the battery pack, reducing labor costs, and further reducing the production cost of the battery pack.
