[0003] The base plate of the mechanism is a fixed part. The operator first places the guide block on the positioning block, then turns the manual switch valve. The parallel gripper cylinder drives the cylinder gripper plate to the left and right to open the guide block. When the parallel gripper cylinder touches the limit block, the operator inserts the lever into the guide block. The operator then turns the manual switch valve, and the parallel gripper cylinder retracts. The operator removes the product, first inserts the positioning shaft of the lever at an angle into the two opposite positioning holes of the guide block, and then rotates the lever. By manually applying force to the lever, the lever is gradually changed from a horizontal state to an inclined state, and the sensitive block is then inserted.

[0004] In the current equipment, these operations are all done manually, which is slow, inefficient, increases labor costs, and causes problems such as misaligned guide blocks and defective products during installation of sensitive blocks.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0018] Reference Figure 1-3 An automatic alignment mechanism for a seatbelt sensitive block includes a square cylinder 100, with a mechanism connecting plate 200 fixedly connected to the telescopic end of the square cylinder 100. The mechanism connecting plate 200 is used to drive the mechanism connecting plate 200 to move up and down to adjust the working height. A cylinder mounting plate 400 is fixedly connected to the rear end of the mechanism connecting plate 200, and a cylinder mounting bracket 500 is fixedly connected to the front end of the cylinder mounting plate 400. A mounting bracket 600 is fixedly connected to the cylinder mounting bracket 500, and a square cylinder 1800 is fixedly connected to the mounting bracket 600. The square cylinder 1800 is used to provide horizontal alignment. The driving force is directed to the piston rod joint 700, which is fixedly connected to the telescopic end of the square cylinder 1800. A rotating hinge seat 800 is rotatably connected to the piston rod joint 700. A parallel gripper cylinder 900 is fixedly connected to the lower bottom surface of the rotating hinge seat 800. A gripper 1100 is connected to the telescopic end of the parallel gripper cylinder 900. A cylinder mounting block 1000 is fixedly connected to the upper end of the parallel gripper cylinder 900. A sliding groove plate 1200 is fixedly connected to both the front and rear ends of the lower bottom surface of the mechanism connecting plate 200. The sliding groove plate 1200 is used to provide a guide trajectory for the movement of the parallel gripper cylinder 900.

[0019] The left and right ends of the cylinder mounting block 1000 are fixedly connected to the cam follower 1300, and the left and right ends of the cylinder mounting block 1000 are tumblingly connected to the slide rail plate 1200 through the cam follower 1300.

[0020] The front end of the slide rail plate 1200 is fixedly connected to a front end limiting installation block 1701, and the rear end of the slide rail plate 1200 is fixedly connected to a rear end limiting installation block 1702.

[0021] A metal washer 1400 is provided between the cam follower 1300 and the slide plate 1200.

[0022] The lower square holes of the two grippers 1100 are used to rotate and install the pivot pin 1500.

[0023] Multiple sets of guide shafts 300 are fixedly connected to the mechanism connecting plate 200.

[0024] The lower end of the 1200 vertical plate of the slide is fixedly installed with a positioning sleeve of 1600.

[0025] In actual use, when the square cylinder 100 is ventilated, the piston rod extends, driving the mechanism connecting plate 200 to move downward along the guide shaft 300 to the designated position, and the left gripper 1100 presses down on the sensitive block stop.

[0026] At this time, the parallel gripper cylinder 900 is located on the right side of the waist groove of the slide plate 1200. After the parallel gripper cylinder 900 is ventilated, the grippers 1100 on both sides rotate through the pivot pin 1500 to clamp the sensitive block.

[0027] Next, the square cylinder 1800 is vented, the piston rod extends, and drives the parallel gripper cylinder 900 to move through the piston rod joint 700 and the rotating hinge seat 800. The cam follower 1300 on both sides of the cylinder mounting block 1000 rolls along the waist groove of the slide plate 1200 with the cooperation of the metal washer 1400 until the front end of the cylinder mounting block 1000 touches the front limit mounting block 1701, and the sensitive block is installed in place.

[0028] After the air supply to the parallel gripper cylinder 900 is cut off, the gripper 1100 releases the sensitive block; the air supply to the square cylinder 100 is cut off, the piston rod retracts, the mechanism connecting plate 200 moves upward to avoid the product, and the sensitive block stop rebounds; the piston rod of the square cylinder 2 1800 retracts, driving the parallel gripper cylinder 900 to reset, until the rear end of the cylinder mounting block 1000 touches the rear end limit mounting block 1702, completing a complete automatic alignment process of the sensitive block.

[0029] During this process, the positioning sleeve 1600 helps ensure the positioning accuracy of the sensitive block, and the guide shaft 300 ensures that the mechanism connecting plate 200 moves smoothly.

[0030] In use, the mechanism mounting plate 200 is fixed on the welding frame, and the guide shaft 300 is connected to the guide shaft 300 connecting plate and the mechanism connecting plate 200 at both ends. When the square cylinder 100 is ventilated, the mechanism connecting plate 200 is pressed down, and the slide plate 1200 is connected to the mechanism connecting plate 200 and pressed down together. The gripper 1100 first presses down the sensitive block stop, and the right square cylinder 1800 is ventilated, which drives the parallel gripper cylinder 900 to push forward until the cylinder mounting block 1000 on the parallel gripper cylinder 900 touches the limit mounting block. The sensitive block is installed in place, the parallel gripper cylinder 900 is de-ventilated, the gripper 1100 is released, the upper square cylinder 100 retracts, the mechanism connecting plate moves up, and the right square cylinder 1800 retracts.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
