[0015] Beneficial Effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 2. By setting a conical rubber sleeve and a sliding splint under the two robotic arm structures respectively, and using the rubber sleeve's unique conical structure and strong adsorption force to transport larger auto parts, it is ensured that large parts will not fall off during the transportation process. The sliding splint can accurately grasp and transport small parts with its flexible sliding characteristics, thereby improving the stacking speed and neatness. At the same time, due to the precise adaptation, the risk of damage to parts caused by improper handling is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the inner cavity of the sliding splint 807 is provided with a lower groove 813 for providing rotation of the shifting block 810, and the shifting block 810 is rotatably connected to the inner cavity of the lower groove 813. The inner cavity of a movable rod 804 is provided with a transverse groove 814 for limiting the two sliding splints 807. , and the inner cavities of the two transverse grooves 814 are slidably connected with four sliding blocks 815, and the four sliding blocks 815 are respectively fixedly connected to the two ends of the two sliding clamps 807, and the inner cavities of the four sliding blocks 815 are rotatably connected with steel balls for increasing flexibility, the outer wall of the sliding pull block 809 is fixedly connected with a fixed block 811, and the shift block 810 is rotatably connected to the inner cavity of the fixed block 811 through a bearing, and the top of the cylindrical groove 806 is fixedly connected with an exhaust pipe 812 for adjusting the height of the sliding pull block 809, and the exhaust pipe 812 is fixedly connected to the upper surface of the cylindrical groove 806. 2 is passed through a movable rod 804 and fixedly connected to the top of the cylindrical groove 806, so that when the gas flows out of the inner cavity of the cylindrical groove 806 through the exhaust pipe 812, the air pressure in the cylindrical groove 806 is reduced to form a low-pressure environment relative to the external atmospheric pressure. Under the action of the external atmospheric pressure, the external air will try to enter the cylindrical groove 806 to balance the pressure difference. Since the sliding block 809 can slide in the cylindrical groove 806 and has a certain sealing performance with the inner wall of the cylindrical groove 806, the external atmospheric pressure will exert an upward pressure on the sliding block 809. , thereby causing the sliding pull block 809 to slide upward, and in the process of moving upward, the fixed block 811 pulls the shift block 810 to flip over. When the shift block 810 flips over, the part of the shift block 810 located in the lower groove 813 of the inner cavity of the sliding clamp 807 pushes the sliding clamp 807. Since the sliding clamp 807 slides in the transverse groove 814 through the sliding blocks 815 at both ends, the push of the shift block 810 causes the two sliding clamps 807 to slide toward each other along the transverse groove 814, thereby realizing a tightening action and firmly clamping the captured small parts.

The exhaust pipe 1 805 and the exhaust pipe 2 812 are both fixedly connected to the top of the air pump 817, and then by driving the air pump 817, the gas in the inner cavities of the exhaust pipe 1 805 and the exhaust pipe 2 812 is extracted at the same time. As the gas in the exhaust pipe 1 805 is extracted, a negative pressure environment is formed inside the conical rubber sleeve 808, and under the action of the external atmospheric pressure, the conical rubber sleeve 808 fits tightly on the top of the larger automotive parts, and uses the adsorption force generated by the atmospheric pressure to firmly fix the parts, ensuring that large parts will not fall off during the transportation process, thereby ensuring the safety and stability of the transportation work, so that the entire automotive parts circulation and conveying equipment can efficiently complete the transportation task of parts of different specifications.

The existence of the block 206 effectively increases the friction between the driven wheel 203, the driving wheel 204 and the belt 205, preventing the belt 205 from slipping during the transmission process, ensuring the stability and reliability of power transmission, enabling the conveyor belt 2 to drive the automobile parts to move at a stable speed, and improving the working efficiency and stability of the entire circulating conveying equipment.

[0044] The working principle of the present invention is: first, the driving motor 207 drives the driving wheel 204 through the transmission of the belt 205, drives the driven wheel 203 and the roller 201 to rotate, and then drives the conveyor belt 2, so that the conveyor belt 2 drives a connecting shell 3 to move to the position corresponding to the protective shell 701, so that the circular magnetic plate 712 and the grooved magnetic sheet 708 are attracted when they are close to each other, and at the same time, the circular magnetic plate 712 pushes the magnetic plug 709 to slide to the other side, and the auto parts to be fixed are placed on the top of the circular cylinder 4, and the air pump 1 702 is driven to inject gas into the inner cavity of the airbag 1 5. In the face of a larger volume When the auto parts are being fixed, the airbag 1 5 pushes all the round cylinders 4 to rise, so that the round cylinders 4 follow the inner shape of the auto parts, automatically adjust their own height, fit in the inner cavity of the auto parts, and fix them. When the auto parts are small, the round cylinder 4 in the middle is suppressed and will not move up. When the airbag 1 5 is inflated, the round cylinders 4 on both sides are pushed up, and the height is adjusted according to the outer shape of the auto parts, fit in the bottom of the auto parts, and wrap and fix them. After driving the air pump 2 703 to inflate the airbag 2 602, the special-shaped top block 601 is pushed up. The two special-shaped fixing rods 603 are squeezed to make the two special-shaped fixing rods 603 slide to both sides respectively, squeezing the sliding rod 401 to limit the position, indirectly positioning the circular cylinder 4 accurately, and extracting the inner cavity gas of the airbag 5, and driving the motor 207 again, so that the conveyor belt 2 drives a connecting shell 3 and the automobile parts fixed above the connecting shell 3 to move, and move to the middle processing area, and after the processing is closed, continue to move between the two mechanical arm structures 8, first select one of the mechanical arm structures 8 according to the size of the automobile parts, and drive the three motors corresponding to it, so that the activity The rod 804 can drive the sliding clamp plate 807 or the conical rubber sleeve 808 to move to the top of the auto parts by rotating, and extract the gas in the inner cavity of the exhaust pipe 1 805 or the exhaust pipe 2 812 by driving the air pump 817. As the gas in the exhaust pipe 1 805 is extracted, a negative pressure environment is formed inside the conical rubber sleeve 808. Under the action of the external atmospheric pressure, the conical rubber sleeve 808 fits tightly on the top of the larger auto parts, so that the larger auto parts can be moved to the top of the fixed plate 9 by the mechanical arm structure 8, and the stacking is completed in sequence.

[0045] When the exhaust pipe 812 extracts the internal gas of the cylindrical groove 806, the air pressure in the cylindrical groove 806 gradually decreases, forming a low-pressure environment. As the air pressure continues to decrease, the sliding block 809 can slide in the cylindrical groove 806, and in the process of the sliding block 809 moving upward, the fixed block 811 pulls the shift block 810 to flip. When the shift block 810 flips, the part of it located in the groove 813 under the inner cavity of the sliding clamp 807 will push the sliding clamp 807 to achieve a tightening action, thereby firmly clamping the grabbed small parts and components, so as to facilitate the mechanical arm structure 8 to move smaller automotive parts to the top of the fixed plate 9, and accumulate and stack them in sequence.

[0046] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
