A ball bearing is fixedly mounted in the bearing seat 7. The two ends of the two screw rods 73 are fixedly mounted in the rotating body of the ball bearing. The outer end of the screw rod 73 is fixedly sleeved with a belt driven pulley. The transmission belt 70 is sleeved on the belt driven pulley. On the moving wheel, the motor base 71 is fixedly mounted on the carrier plate 11, the second driving motor 72 is fixedly mounted on the motor base 71, the output shaft of the second driving motor 72 is fixedly sleeved with a driving wheel, the driving wheel is transmission-connected with the transmission belt 70, the guide sleeve 75 and the transmission sleeve 76 are both fixedly mounted on the movable seat 42, the transmission sleeve 76 is further threadedly sleeved on the screw rod 73, both ends of the guide rod 74 are fixedly mounted on the bearing seat 7, the guide sleeve 75 is fixedly mounted on the guide rod 74 in a sliding sleeve;

[0027] The automatic unlocking and locking mechanism 8 is composed of a four-axis manipulator 80, a clamping cylinder 82, a camera 83 and a displacement sensor 84. The camera 83, the displacement sensor 84 and the cylinder body of the clamping cylinder 82 are all fixedly mounted on the execution end of the four-axis manipulator 80. The clamping cylinder 82 has an assembly and disassembly clamping claw 81.

[0028] The blocking cylinder 64, the pressing cylinder, and the clamping cylinder 82 are respectively connected to the air pressure station through pipelines. The air pressure station, the first drive motor 65, the second drive motor 72, the four-axis manipulator 80, the camera 83 and the displacement sensor 84 are all connected to the control module through circuits.

[0029] It also includes a telescopic protective sleeve 77, both ends of which are fixedly installed in the fixed seat 41 and the movable seat 42. The screw rod 73, guide rod 74, guide sleeve 75 and transmission sleeve 76 are all located in the telescopic protective sleeve 77 to form protection for the screw rod 73, guide rod 74, guide sleeve 75 and transmission sleeve 76 to prevent dust from sticking to the screw rod 73 and the guide rod 74, causing jamming during operation.

[0032] The product is fixed on the fixture 10. The blocking cylinder 64 and the downward pressure cylinder are both linear telescopic cylinders. The control module controls the first drive motor 65 to start. The first drive motor 65 drives the sprocket and the conveyor chain 61 to run. The fixture 10 is placed on the conveyor chain 61 and runs synchronously with it. At this time, the piston rod of the blocking cylinder 64 drives the L-shaped blocking plate to move downward. When the in-position sensor 63 detects the fixture 10, it sends an electrical signal to the control module. The control module controls the first drive motor 65 to stop running. At this time, the fixture 10 is blocked and limited by the L-shaped blocking plate. The downward pressure cylinder of the control module drives the downward pressure frame to move downward to press the fixture 10 and position it on the conveyor chain 61. The control module controls the execution end of the four-axis manipulator 80 to move When it reaches the top of the product's operating point, the data signal is fed back to the control module in real time through the camera 83 and the displacement sensor 84, so that the assembly and disassembly clamping claw 81 is aligned with the buckle at the product's operating point. The control module controls the execution end of the four-axis manipulator 80 to rotate, and the clamping cylinder 82 controls its assembly and disassembly clamping claw 81 to lock and remove the buckle on the product. Similarly, the assembly and disassembly clamping claw 81 can also clamp the buckle and install it on the product. After the assembly / disassembly operation is completed, the control module controls the downward pressure cylinder to drive the downward pressure frame to move upward, release the clamping effect on the fixture 10, control the blocking cylinder 64 to drive the L-shaped blocking plate to move upward, release the blocking and limiting effect on the fixture 10, control the first drive motor 65 to start, and the fixture 10 flows out with the conveyor chain 61.

[0033] When adjusting the spacing between the two beams 3 according to products and fixtures 10 of different widths, the second drive motor 72 is started by controlling the module, and the transmission belt 70 and the belt driven pulley are driven to run through the drive wheel. The belt driven pulley synchronously drives the screw rod 73 to rotate, and the screw rod 73 drives the combination of the transmission sleeve 76, the movable seat 42, and the guide sleeve 75 to move back and forth along the guide rod 74, thereby adjusting the spacing between the two beams 3 to meet the use requirements of products and fixtures 10 of various sizes.
