Referring to fig. 2 and 3, the product 200 to be positioned may be manually or mechanically pushed onto the plurality of rollers 120 and may be moved in a first direction over the plurality of rollers 120. Before positioning, the clamping driving assembly 150 can drive the clamping member 140 to rotate, so that the clamping member 140 is separated from the position right above the plurality of rollers 120, and normal movement of the product 200 is prevented from being affected.

During positioning, the product 200 can move until the front end of the product 200 abuts against the blocking member 130, then the clamping member 140 is driven to rotate by the clamping driving assembly 150, and the product enters the position right above the plurality of rollers 120 and continues to rotate until the product abuts against the rear end of the product 200, so that the two ends of the product 200 are respectively abutted against the first blocking member 130 and the clamping member 140, and the movement of the product 200 in the first direction is limited, so that the positioning of the product 200 is completed.

In some embodiments, referring to fig. 4, the clamping member 140 includes a clamping portion 141, a rotating portion 142 and a connecting portion 143 sequentially connected, the rotating portion 142 is rotatably disposed on the mounting frame 110, the rotation axis of the rotating portion 142 is along a vertical direction, and the connecting portion 143 is connected to the driving end of the clamping driving assembly 150.

To facilitate movement of the product 200 when the product 200 is pushed onto the drum 120, a gap may exist between the first barrier 130, the product 200, and the second barrier 160. The application defines that the second direction is perpendicular to the first direction, and the side pushing assembly 180 pushes the product 200 to move along the second direction, and abuts the product 200 against the third blocking member 170, so as to limit the movement of the product 200 in the second direction.

The side pushing assembly 180 may include a side pushing cylinder and a pushing block disposed on a piston rod of the side pushing cylinder. Before positioning, the piston rods of the side pushing cylinders are contracted, so that the pushing blocks are positioned at the outer sides of the plurality of rollers 120, and the influence on the movement of the product 200 is avoided; after the product 200 abuts the first stop 130, the piston rod of the side push cylinder extends, causing the push block to move past the second opening 162 and then over the plurality of rollers 120 and pushing the product 200 against the third stop 170.
