At the same time, the moving paths between the transfer robots are optimized and do not interfere with each other; the single moving travel distance of the transfer robot is close to that of the traditional transfer robot, which effectively improves the production efficiency and production stability of the box covering.

At the same time, the first drive motor 421 and the rotating shaft 430 are distributed on the bottom surface of the connecting plate 110, which is conducive to significantly reducing the load of the connecting plate 110 and improving the structural stability of the connecting plate 110.

When the height exceeds the preset range, the cover body is affected by the height limiting portion 221 and cannot move to the preset position, which helps prevent the transfer unit 500 from mistakenly installing the wrong cover body.

[0051] When the cover passes through the cover radial positioning unit 222, the cover radial positioning unit 222 pushes the cover along the radial direction of its conveying path until the cover is in close contact with the edge of the cover flow channel to achieve radial positioning.

Specifically, two groups of the second limit baffles 310 are relatively close to or away from each other along the adjusting transverse plate 120 through the bending plate, thereby realizing the width adjustment of the box body flow channel, so as to adapt to boxes of different widths, and further improve the practicality of the cover box device.

[0056] Specifically, the box body radial positioning unit 321 has the same structure as the cover body radial positioning unit 222, and the box body clamping positioning unit 323 includes a linear cylinder and a clamping finger arranged at the output end of the linear cylinder; when the box body detection unit 324 recognizes that the box body has moved to the preset position, the box body axial positioning unit 322 brakes the box body, and the linear cylinder drives the clamping finger to drive in the direction of the box body, so that the clamping finger clamps the box body, so that the transfer unit 500 can assemble the cover body on the box body. After the assembly is completed, the box body axial positioning unit 322 releases the box body, and the box body is driven to the preset unloading position via the box body conveyor line 300. In this embodiment, the box body axial positioning unit 322 includes a cylinder and a brake block arranged on the telescopic rod of the cylinder, and the cylinder can drive the brake block to move to the moving path of the box body.
