[0044] More preferably, the opening and closing drive device includes an opening and closing cylinder 3131, a cylinder seat 3132, and a drive connector 3133.

A T-shaped drive connector is connected to the output end of the opening and closing cylinder. The drive connector is rotatably connected to the opening and closing extension.

[0045] The steps for using the adaptive anti-collision feeding mechanism include:

[0046] The accumulating roller conveyor unit moves the dual-station material box to the dropping position. A baffle rises to limit the box's position. The three-axis transfer unit moves the hopper discharge unit above the dual-station material box. External grippers drop the material into the discharge bin body. The feeding sensor detects the feeding and sends a signal to the controller. At this time, the opening / closing door is closed to catch the product. The controller receives the feeding signal and information about the material (mainly its height) and the material's placement in the corresponding box (left or right). It then controls the three-axis transfer unit to move the hopper discharge unit above the corresponding box. At this point, the slider is at the bottom of the linear guide rail. The lower position sensor and position sensing element work together to sense the position of the discharge bin body. The Z-axis screw module drives the discharge bin body to move continuously downwards. After the bottom of the discharge bin body touches the bottom of the material box / material, As the Z-axis lead screw module continues to move downwards, the main body of the discharge bin moves upwards along the linear slide rail. When the main body of the discharge bin moves upwards to the position sensor, the Z-axis lead screw module moves upwards to achieve flexible feeding layer recognition. After the lower position sensor senses the position sensor again, the Z-axis lead screw module continues to move upwards by the height of one material, so that the height of the material falling freely is the height of one material, avoiding impact and collision during free fall. The controller controls the 57 opening and closing cylinder to open the opening and closing door to release the material. Before opening the opening and closing door, the relative position of the main body of the discharge bin and the box is determined by the movement distance of the sensor, CCD, or three-axis transfer unit. When the main body of the discharge bin is close to the left / right side wall of the box, the controller can control only the right / left opening and closing door to release the material. When the main body of the discharge bin is in the middle of the box, the controller can open the opening and closing doors on both sides simultaneously to release the material. After the material is released, the controller controls the main body of the discharge bin to reset and close the opening and closing door, and this cycle continues.

[0047] The beneficial effects of this adaptive anti-collision feeding mechanism are: it can achieve uninterrupted continuous feeding, greatly improve the feeding cycle, increase production capacity, and achieve adaptive stacking and irregular stacking effects, avoiding material impact damage and jamming, improving the efficiency, accuracy and stability of feeding, and also improving the compatibility within the product's size range, which can meet different usage needs.
