[0039] It can be understood that in order to achieve reliable positioning and adaptability of the product, in this embodiment, Figure 3 and Figure 4 As shown in , a support member is provided on the base 10 corresponding to the positioning area, and the support member is used to support and position the product located in the positioning area. Preferably, the support member is a support block 3.

[0040] Action description: The base 10 is installed on the mounting base 50 of the conveyor line 5. As the conveyor line 5 drives the entire battery tray to flow, the rectangular spring 122 is naturally extended, and the driving beam 120 is pushed by the rectangular spring 122 to a position away from the limit block of the support block 3 and stops, driving the connecting rod assembly 124 to rotate, so that the positioning block opening and closing mechanism 12 is closed (such as Figure 2 As shown), at this time, the first positioning block 110 and the second positioning block 111 are reset and closed (parallel to the length direction of the tray after closing), the support block 3 and the fixed block positioning assembly 6 together form a rectangular groove for battery cell transportation;

[0048] The working principle of the present invention is briefly described as follows, in which the product is a battery cell for illustration: a tray 1 is installed on a conveyor line 5 and transported along the conveyor line 5, the battery cell is placed upright on a fixed block positioning assembly 6 of the tray, the length direction of the battery cell (first direction) is consistent with the length direction of the tray, the pole is facing upward, the bottom surface of the battery cell is supported by the recessed upper surface of the fixed block positioning assembly 6 of the tray and the upper surface of the support block 3, the length direction is limited by the side surface of the protrusion of the fixed block positioning assembly 6, the thickness direction (second direction) is limited by the side surface of the protrusion of the fixed block positioning assembly 6 and the first positioning block 110 and the second positioning block 111, the positioning block opening and closing mechanism 12 is controlled by a connecting rod assembly 123, a rectangular spring 122, a guide shaft 121 and a linear bearing to control the opening and closing state, when the tray 1 is transported along the conveyor line 5, the rectangular spring 122 naturally extends, and the open and close positioning assembly 11 is closed, so as to achieve in the transportation process. Limit the thickness direction of the battery cell; when the tray is located at the working position, the cylinder 41 of the tray opening mechanism 4 extends out, compresses the rectangular spring 122, and the open and close positioning component 11 opens. At the same time, the clamping claw cylinder 440 of the tray opening mechanism 4 is clamped to realize the positioning and fixation of the battery cell, which is convenient for the operation of the work station equipment. While the cylinder 41 of the tray opening mechanism 4 compresses the rectangular spring 122, it can provide support for the non-processed large surface of the battery cell. When the plasma cleaning process needs to be carried out on both sides of the battery cell at the same time, the support function can also be cancelled by changing the form and installation position of the cylinder. One side of the processing surface on both sides of the battery cell is completely open, and the other side is only partially blocked by the positioning block. Both sides can be operated at the same time. When the battery cell is subjected to operations such as gluing, rolling glue, tearing off the mold paper, and testing, one side of the processing surface on both sides of the battery cell is completely open for equipment operation, and one side is supported by the cylinder of the tray opening mechanism for auxiliary operation.
