Description

Technical Field

[0001] This invention relates to the field of automotive parts conveying technology, specifically to a circulating conveying device for automotive parts. Background Technology

[0002] In the automotive manufacturing industry, the transportation of parts is one of the key links in the production process. Automotive manufacturing is a highly complex and precise process involving the assembly and processing of tens of thousands of parts. These parts need to be transported efficiently and accurately between different production processes to ensure the smooth operation of the production line and the quality of the final product.

[0003] Chinese patent discloses a circulating conveying device for automotive parts (publication number CN210883823U). This patent includes a base, a horizontal drive mechanism, a vertical drive mechanism, and an automotive parts conveying mechanism. The horizontal drive mechanism is disposed on the base and is drivenly connected to the vertical drive mechanism. The automotive parts conveying mechanism is disposed on the horizontal drive mechanism via the vertical drive mechanism and is drivenly connected to the automotive parts conveying mechanism. The horizontal drive mechanism can drive the vertical drive mechanism to move the automotive parts conveying mechanism horizontally, and the vertical drive mechanism can drive the automotive parts conveying mechanism to move vertically. The automotive parts conveying mechanism is a dual conveying mechanism arranged vertically and vertically in opposite directions.

[0004] Therefore, based on the above-mentioned research and in conjunction with existing information, in the automotive manufacturing industry, the transportation of auto parts is a crucial link in the production process. However, when using the aforementioned devices to transport auto parts, the devices cannot fix the auto parts in place. Furthermore, the varying shapes and sizes of auto parts result in dispersed and uncontrollable stress points, leading to shaking and displacement of auto parts during transportation, causing collisions with other parts, resulting in surface scratches, deformation, or even breakage, severely impacting product quality. In addition, for some precision and fragile auto parts, even slight shaking and displacement can damage internal precision components, causing irreparable damage. Therefore, this invention provides a circulating transportation device for auto parts to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a circulating conveying device for automotive parts to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A base is included, the inner cavity of which is rotatably connected to a conveyor belt for moving automotive parts. Multiple connecting shells are fixedly connected to the top outer wall of the conveyor belt. Multiple circular cylinders for fixing automotive parts are slidably connected inside the connecting shells, and the arrangement height of the circular cylinders is adjusted according to the shape of the automotive parts to achieve stable fixing of automotive parts of different shapes. An airbag for pushing the circular cylinders to fit against the underside of the automotive parts is fixedly installed inside the connecting shell. A positioning structure for limiting the position of the circular cylinders is installed inside the connecting shell. Both sides of the outer wall of the base are fixedly connected to... The device comprises two irregularly shaped rods, each with a robotic arm structure fixedly mounted on its outer wall for transferring automotive parts from a conveyor belt to other equipment. The robotic arm structure handles automotive parts of different shapes and stacks them. Two sliding clamps for handling smaller automotive parts are fixedly mounted on the bottom of one robotic arm structure, and a conical rubber sleeve for handling larger parts is fixedly mounted on the bottom of the other robotic arm structure. Fixed plates for storing automotive parts are fixedly connected to the bottom of both robotic arm structures. The robotic arm structure precisely transports automotive parts from the conveyor belt to the top of the fixed plate and stacks them sequentially.

[0007] Furthermore, both ends of the cylindrical tube are slidably connected with connecting sliding rods for limiting the sliding of the cylindrical tube, and the inner cavity of the connecting shell is fixedly connected with an extension rod for limiting the sliding rod, and the extension rod prevents the sliding rod from moving upward and disengaging from the inner cavity of the connecting shell.

[0008] Furthermore, the positioning structure includes an irregularly shaped top block, which is slidably connected to the inner cavity of the connecting shell. An airbag II for pushing the irregularly shaped top block upward is fixedly installed at the bottom of the inner cavity of the connecting shell, and an irregularly shaped fixing rod for positioning the cylindrical tube is fixedly connected to the inner cavity of the connecting shell.

[0009] Furthermore, a protective shell is fixedly installed on the top of one of the irregular rods, and an air pump one for supplying gas to the inside of airbag one is fixedly installed in the inner cavity of the protective shell. An air pump two for supplying gas to the inside of airbag two is fixedly connected above the air pump one.

[0010] Furthermore, the robotic arm structure includes a sleeve plate, which is fixedly connected to the outer wall of the irregular rod. A clamping block is rotatably connected to the top of the sleeve plate, and a bent rod is rotatably connected to the inner cavity of the clamping block. A movable rod is rotatably connected to the inner cavity of the bent rod.

[0011] Furthermore, two sliding clamps for handling smaller automotive parts are fixedly installed at the bottom of one of the robotic arm structures. A cylindrical groove is provided in the inner cavity of one of the movable rods. A sliding pull block is slidably connected to the inner cavity of the cylindrical groove. A lever for pushing the two sliding clamps to tighten and loosen is rotatably connected to the outer wall of the sliding pull block.

[0012] Furthermore, a conical rubber sleeve for handling larger parts is fixedly installed at the bottom of one of the robotic arm structures. The conical rubber sleeve is fixedly connected to the bottom of a movable rod. An air extraction pipe for extracting gas is fixedly installed at the top of the conical rubber sleeve, and the outer wall of the air extraction pipe penetrates a movable rod and is fixedly connected to the top of the conical rubber sleeve.

[0013] Furthermore, the inner cavity of the conveyor belt is rotatably connected to a roller for driving the conveyor belt to rotate. One end of the roller is fixedly connected to a driven wheel, and the lower part of the roller is rotatably connected to a driving wheel for driving the roller to rotate. The driven wheel and the outer wall of the driving wheel are rotatably connected to a belt for transmission.

[0014] Furthermore, in order to enhance the transmission effect, the outer walls of both the driven wheel and the driving wheel are fixedly connected with resistance blocks to increase friction. Multiple resistance blocks are provided and are distributed in an array on the outer walls of the driven wheel and the driving wheel, and the resistance blocks are located inside the belt.

[0015] Beneficial effects

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention, by setting multiple cylindrical tubes, can adapt to automotive parts of different sizes and shapes. When fixing a large automotive part, the airbag inflates to push multiple cylindrical tubes upwards simultaneously. These tubes adjust their height to follow the curvature of the automotive part's inner cavity, thus fitting snugly against the part and supporting it from the inside. When a small automotive part is used, the airbag pushes multiple cylindrical tubes on both sides upwards. During this movement, the airbag flexibly adjusts its height according to the edge shape of the part, wrapping and fixing it. This adapts to automotive parts of different sizes, reducing the time cost of replacement and adjustment. At the same time, the inflating airbag pushes the cylindrical tubes to fit snugly against the inner cavity, effectively dispersing the fixing force and preventing the parts from shaking or shifting during transport due to uneven local force.

[0018] 2. By installing conical rubber sleeves and sliding clamps under the two robotic arm structures, the rubber sleeves utilize their unique conical structure and strong suction force to handle larger automotive parts, ensuring that large parts will not fall off during handling. Meanwhile, the sliding clamps, with their flexible sliding characteristics, can accurately grasp and handle small parts, improving the stacking speed and neatness. At the same time, due to the precise fit, the risk of damage to parts caused by improper handling is reduced. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1-10A circulating conveying device for automotive parts includes a base 1. A conveyor belt 2 for moving automotive parts is rotatably connected to the inner cavity of the base 1. Multiple connecting shells 3 are fixedly connected to the top outer wall of the conveyor belt 2, with two connecting shells per group, fixed to the top of the conveyor belt 2 by connecting plates. Multiple groups of connecting shells 3 are provided, and automotive parts are continuously conveyed through these multiple connecting shells 3, forming an efficient and orderly circulating conveying chain for automotive parts. Multiple circular cylinders 4 for fixing automotive parts are slidably connected inside the connecting shells 3, and the arrangement height of the circular cylinders 4 is adjusted according to the shape of the automotive parts. When the automotive parts are large... When the airbag 5 inflates, it simultaneously pushes multiple cylindrical tubes 4 upwards, adjusting their height to conform to the curved shape of the car part's inner cavity, thus supporting it and ensuring the car part does not wobble during transport. When the car part is small, the airbag 5 simultaneously pushes the multiple cylindrical tubes 4 upwards. Because the top of the middle cylindrical tube 4 is pressed by the car part, it will not move upwards, while the cylindrical tubes on both sides are not restricted and will continue to move upwards. During the movement, they flexibly adjust their height according to the edge shape of the car part. Ultimately, the multiple cylindrical tubes 4 will successfully enclose the car part. The parts are encased inside, and this tight wrapping ensures that the automotive parts will not shake during transportation. An airbag 5 is fixedly installed inside the connecting shell 3 to push the cylindrical cylinder 4 against the underside of the automotive parts. The airbag 5 is located below the cylindrical cylinder 4, and its inflating pushes the cylindrical cylinder 4 upwards to adhere to the underside of the automotive parts. A positioning structure 6 is installed inside the connecting shell 3 to limit the movement of the cylindrical cylinder 4. Irregularly shaped rods 7 are fixedly connected to both sides of the outer wall of the base 1, and a robotic arm structure 8 for transporting automotive parts is fixedly installed on the outer walls of both rods 7. Different shaped rods 7 are transported by the robotic arm structure 8. The system stacks automotive parts. Two sliding clamps 807 are fixedly installed at the bottom of one robotic arm structure 8 for handling smaller automotive parts. The sliding clamps 807 can accurately grasp and handle small parts by means of their flexible sliding characteristics. A conical rubber sleeve 808 is fixedly installed at the bottom of another robotic arm structure 8 for handling larger parts. The sleeve uses its strong suction force to steadily handle large parts. Fixed plates 9 for storing automotive parts are fixedly connected to the bottom of both robotic arm structures 8. The robotic arm structure 8 moves the automotive parts to the top of the fixed plates 9 and stacks them one by one.

[0033] See also Figures 2-4Both ends of the cylindrical cylinder 4 are slidably connected to connecting sliding rods 401 to limit the sliding of the cylindrical cylinder 4. An extension rod 402 for limiting the sliding rod 401 is fixedly connected to the inner cavity of the connecting shell 3. The sliding rods 401 and extension rods 402 are arranged in pairs, with multiple pairs provided, the number being the same as that of the cylindrical cylinder 4. The extension rods 402 prevent the sliding rod 401 from detaching from the inner cavity of the connecting shell 3 when it moves upward. Specifically, the inner cavity of the sliding rod 401 has a vertical groove 404 for providing space for the extension rod 402. The sliding space is provided, and the extension rod 402 is slidably connected to the inner cavity of the vertical groove 404. The inner cavity of the connecting shell 3 is provided with a strip groove 403 for providing sliding for the sliding rod 401. The number of strip grooves 403 is the same as that of the sliding rod 401, and the sliding rod 401 is slidably connected to the inner cavity of the strip groove 403. The extension rod 402 is fixedly installed on the inner wall of the strip groove 403 to ensure that the cylindrical cylinder 4 always moves within a controllable range and will not fail to fix due to excessive movement, so that the entire conveying process is carried out smoothly.

[0034] Please see Figures 2-4 The positioning structure 6 includes an irregularly shaped top block 601, which is slidably connected to the inner cavity of the connecting shell 3. An airbag 602 for pushing the irregularly shaped top block 601 upward is fixedly installed at the bottom of the inner cavity of the connecting shell 3. An irregularly shaped fixing rod 603 for positioning the cylindrical cylinder 4 is fixedly connected to the inner cavity of the connecting shell 3. Specifically, two irregularly shaped fixing rods 603 are provided, and the two rods 603 are located on both sides of the irregularly shaped top block 601. When the irregularly shaped top block 601 moves upward, it squeezes the two fixing rods 603, causing the two irregularly shaped top blocks 601 to... When the fixed rod 603 slides to both sides, it presses and limits the sliding rod 401, indirectly and accurately positioning the cylindrical cylinder 4. As a result, during the conveying of automotive parts, the cylindrical cylinder 4 can always remain in the set position, thus stably fixing and limiting the automotive parts. This effectively avoids problems such as unstable fixing and falling of parts caused by the displacement of the cylindrical cylinder 4, greatly improving the reliability and stability of the entire circulating conveying equipment during operation, and ensuring that automotive parts can be safely and efficiently conveyed to the designated position.

[0035] More specifically, both sides of the inner cavity of the connecting shell 3 are provided with transverse sliding grooves 604 for limiting the irregular fixed rods 603. The inner cavities of the two transverse sliding grooves 604 are slidably connected to two irregular sliding rods 605, and the four irregular sliding rods 605 are respectively fixedly connected to the two ends of the two irregular fixed rods 603, ensuring that the irregular fixed rods 603 can only slide smoothly along the direction of the transverse sliding grooves 604, avoiding the deviation or jamming caused by uneven force, making the squeezing and limiting action of the sliding rod 401 more stable and reliable.

[0036] A positioning plate 501 for positioning airbag 5 is fixedly connected to the lower part of airbag 5, and the positioning plate 501 is located above the irregular top block 601.

[0037] Please see Figure 2 and Figures 5-6 A protective shell 701 is fixedly installed on the top of an irregular rod 7. An air pump 702 for supplying gas to the inside of airbag 5 is fixedly installed inside the protective shell 701. An air pump 703 for supplying gas to the inside of airbag 602 is fixedly connected above the air pump 702. Specifically, a connecting bend plate 707 is fixedly connected to the end of the protective shell 701 away from the connecting shell 3, and the connecting bend plate 707 is fixed to the top of the irregular rod 7 by bolts. An air supply structure 704 is fixedly installed near the connecting shell 3 for the air pump 702 and the air pump 703. Both the air pump 702 and the air pump 703 are connected to airbag 5 and airbag 602 through the air supply structure 704. When the connecting shell 3 moves to the side of the air pump 702 and the air pump 703, the air pump 704 inflates the inside of airbag 5 and airbag 602 respectively.

[0038] More specifically, the gas transmission structure 704 includes a gas transmission pipe 705. One end of the gas transmission pipe 705 near the protective shell 701 is fixedly connected to a first air pump 702 and a second air pump 703, respectively. A second gas transmission pipe 706 is fixedly connected to one side of the gas transmission pipe 705, and the end of the second gas transmission pipe 706 away from the gas transmission pipe 705 passes through the connecting shell 3 and is fixedly connected to an first airbag 5 and a second airbag 602, respectively. A grooved magnetic sheet 708 is fixedly installed in the inner cavity of the second gas transmission pipe 706. A magnetic insert 709 for preventing gas leakage is slidably connected to the inner cavity of the grooved magnetic sheet 708. Multiple extension grooves 710 are provided in the inner cavity of the second gas transmission pipe 706 for limiting the magnetic insert 709. A slider 711 is slidably connected to the inner cavity of the extension groove 710, and the slider 711 is fixedly connected to the outer wall of the magnetic insert 709, allowing the magnetic insert 709 to pass through the extension groove. 710 A preset path is installed in the inner cavity of the second gas pipeline 706. The inner cavity of the first gas pipeline 705 is fixedly connected to a circular magnetic plate 712 for pushing the magnetic plug 709 to slide. The circular magnetic plate 712 and the magnetic plug 709 repel each other, and the circular magnetic plate 712 and the grooved magnetic sheet 708 attract each other. When the connecting shell 3 moves to one side of the first air pump 702 and the second air pump 703, the circular magnetic plate 712 and the grooved magnetic sheet 708 are attracted to each other. At the same time, the circular magnetic plate 712 pushes the magnetic plug 709 to slide to the other side, so that the gas enters the interior of the first airbag 5 and the second airbag 602 respectively. After the connecting shell 3 gradually moves away from the first air pump 702 and the second air pump 703, when the circular magnetic plate 712 and the grooved magnetic sheet 708 separate, the grooved magnetic sheet 708 and the magnetic plug 709 attract each other. Therefore, the magnetic plug 709 can be reset by magnetic force, thereby preventing gas leakage.

[0039] Example 2: Please refer to Figures 7-9A circulating conveying device for automotive parts, differing from Embodiment 1 in that the robotic arm structure 8 includes a sleeve 801, which is fixedly connected to the outer wall of the irregular rod 7. A clamping block 802 is rotatably connected to the top of the sleeve 801 via a rotating rod three. A bent rod 803 is rotatably connected to the inner cavity of the clamping block 802 via a rotating rod one. A movable rod 804 is rotatably connected to the inner cavity of the bent rod 803 via a rotating rod two. Specifically, a motor three for driving the clamping block 802 to rotate is fixedly installed in the inner cavity of the sleeve 801, and the output shaft of the motor three is fixedly connected to the rotating rod three. A motor one for driving the bent rod 803 to rotate within the inner cavity of the clamping block 802 is fixedly installed on the top of the sleeve 801, and the motor one… The output shaft of the mechanical arm is fixedly connected to the rotating rod 1. The inner cavity of the bent rod 803 is fixedly installed with a motor 2 for driving the movable rod 804 to rotate inside it. The output shaft of the motor 2 is fixedly connected to the rotating rod 2. When handling irregularly shaped automotive parts, the three motors can be driven to make the movable rod 804 conform to the contour of the parts by rotation, which enhances the stability of gripping and makes the operation of the robotic arm structure 8 more precise and efficient. It can quickly respond to the handling needs on the production line, improve the working efficiency of the entire circulating conveyor equipment, and ensure the smooth handling of automotive parts from the conveyor belt 2 to the fixed plate 9. This provides strong support for the subsequent stacking of parts and the continuity of the production process.

[0040] See also Figures 9-10A movable rod 804 has a cylindrical groove 806 inside its cavity. A sliding block 809 is slidably connected to the cavity of the cylindrical groove 806. A lever 810 for tightening and loosening two sliding clamps 807 is rotatably connected to the outer wall of the sliding block 809. Specifically, the sliding clamps 807 have a lower groove 813 inside their cavities to allow the lever 810 to rotate, and the lever 810 is rotatably connected to the cavity of the lower groove 813. A movable rod 804 has a transverse groove 814 inside its cavity for limiting the movement of the two sliding clamps 807. Furthermore, four sliding blocks 815 are slidably connected to the inner cavities of the two transverse grooves 814, and the four sliding blocks 815 are respectively fixedly connected to the two ends of the two sliding clamps 807. The inner cavities of the four sliding blocks 815 are rotatably connected to steel balls to increase flexibility. A fixing block 811 is fixedly connected to the outer wall of the sliding pull block 809, and a lever 810 is rotatably connected to the inner cavity of the fixing block 811 via a bearing. An air extraction pipe 812 for adjusting the height of the sliding pull block 809 is fixedly connected to the top of the cylindrical groove 806, and the air extraction pipe 812... A movable rod 804 is fixedly connected to the top of the cylindrical groove 806 through the outer wall of the 2. When gas flows out of the inner cavity of the cylindrical groove 806 through the exhaust pipe 812, the air pressure inside the cylindrical groove 806 decreases, forming a low-pressure environment relative to the external atmospheric pressure. Under the action of the external atmospheric pressure, outside air will try to enter the cylindrical groove 806 to balance the pressure difference. However, since the sliding block 809 can slide inside the cylindrical groove 806 and has a certain sealing performance with the inner wall of the cylindrical groove 806, the external atmospheric pressure exerts an upward force on the sliding block 809. The pressure causes the sliding block 809 to slide upwards. During the upward movement, the fixed block 811 pulls the lever 810 to flip. When the lever 810 flips, the part of it located in the groove 813 of the inner cavity of the sliding clamp 807 pushes the sliding clamp 807. Since the sliding clamp 807 slides within the transverse groove 814 through the sliding blocks 815 at both ends, the push of the lever 810 causes the two sliding clamps 807 to slide towards each other along the transverse groove 814, thereby achieving a tightening action and firmly clamping the small parts being gripped.

[0041] Please see Figures 7-8A conical rubber sleeve 808 is fixedly connected to the bottom of a movable rod 804. A gas extraction pipe 805 for drawing gas is fixedly installed on the top of the conical rubber sleeve 808, and the outer wall of the gas extraction pipe 805 penetrates the movable rod 804 and is fixedly connected to the top of the conical rubber sleeve 808. Specifically, both the outer walls of the gas extraction pipe 805 and the second gas extraction pipe 812 are fixedly connected to retaining rings 816, which are fixedly connected to the outer walls of the bent rod 803 and the movable rod 804. Thus, the retaining rings 816 fix the gas extraction pipe 805 and the second gas extraction pipe 812 to the outer walls of the two sets of bent rods 803 and the movable rod 804 respectively. An air pump 817 for drawing gas is fixedly installed in the inner cavity of the base 1. Furthermore, both the first suction pipe 805 and the second suction pipe 812 are fixedly connected to the top of the air pump 817. By driving the air pump 817, the gas inside the chambers of the first suction pipe 805 and the second suction pipe 812 is simultaneously extracted. As the gas in the first suction pipe 805 is extracted, a negative pressure environment is formed inside the conical rubber sleeve 808. Under the action of external atmospheric pressure, the conical rubber sleeve 808 tightly adheres to the top of the large automotive parts. The suction force generated by atmospheric pressure firmly fixes the parts, ensuring that large parts will not fall off during transportation. This ensures the safety and stability of the transportation work, enabling the entire automotive parts circulation conveying equipment to efficiently complete the transportation tasks of parts of different specifications.

[0042] Example 3: Please refer to Figure 11 A circulating conveying device for automotive parts, differing from Embodiment 1 in that the inner cavity of the conveyor belt 2 is rotatably connected to a roller 201 for driving the conveyor belt 2 to rotate. Specifically, the inner cavity of the base 1 is fixedly installed with an extension block 202 for limiting the roller 201, and both ends of the roller 201 are rotatably connected to the inner cavity of the extension block 202 via bearings. One end of the roller 201 is fixedly connected to a driven wheel 203, and one end of the roller 201 passes through an extension block 202 and is fixedly connected to the driven wheel 203. Below the roller 201, a roller for driving the conveyor belt 2 is rotatably connected to a roller. The drive wheel 204 rotates on shaft 201, and the driven wheel 203 is rotatably connected to the outer wall of the drive wheel 204 by a belt 205 for transmission. Specifically, a motor 207 for driving the drive wheel 204 to rotate is fixedly installed in the inner cavity of the base 1, and the output shaft of the motor 207 is fixedly connected to the drive wheel 204. After the motor 207 starts, it drives the drive wheel 204 to rotate. The drive wheel 204 drives the driven wheel 203 to rotate through the transmission of the belt 205, thereby causing the roller 201 to rotate, realizing the stable operation of the conveyor belt 2 and providing power support for the transportation of automotive parts.

[0043] See also Figure 11To enhance the transmission effect, the outer walls of both the driven wheel 203 and the driving wheel 204 are fixedly connected with resistance blocks 206 to increase friction. Multiple resistance blocks 206 are arranged in an array on the outer walls of the driven wheel 203 and the driving wheel 204, and the resistance blocks 206 are located inside the belt 205. The presence of the resistance blocks 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 transmission, ensuring the stability and reliability of power transmission, enabling the conveyor belt 2 to drive the automotive parts at a stable speed, and improving the working efficiency and stability of the entire circulating conveying equipment.

[0044] The working principle of this invention is as follows: First, the drive motor 207 drives the drive wheel 204 to rotate via the belt 205, which in turn drives the driven wheel 203 and roller 201 to rotate. This, in turn, drives the conveyor belt 2, causing the conveyor belt 2 to move a connecting shell 3 to a position corresponding to the protective shell 701. When the circular magnetic plate 712 and the grooved magnetic sheet 708 approach each other, they attract each other. At the same time, the circular magnetic plate 712 pushes the magnetic insert 709 to slide to the other side. The automotive parts that need to be fixed are placed on top of the circular cylinder 4, and the air pump 702 is driven to inject gas into the inner cavity of the airbag 5. When facing a large volume... When the car part is inflated, airbag 5 pushes multiple cylindrical cylinders 4 upwards, causing them to automatically adjust their height to fit the inner cavity of the car part and secure it. When the car part is small, the middle cylindrical cylinder 4 is compressed and will not move upwards. When airbag 5 inflates, it pushes the cylindrical cylinders 4 on both sides upwards, adjusting their height to fit the outer shape of the car part and securing it to the bottom. After airbag 602 inflates due to the driving air pump 703, it pushes the irregularly shaped top block 601 upwards. When the two irregularly shaped fixing rods 603 are pressed together, causing them to slide to both sides, they limit the sliding rod 401, indirectly and precisely positioning the cylindrical cylinder 4. This also extracts the gas from the inner cavity of the airbag 5. Simultaneously, the motor 207 is driven again, causing the conveyor belt 2 to move a connecting shell 3 and the automotive part fixed above it. After moving to the central processing area and closing the processing, the conveyor belt continues to move between the two robotic arm structures 8. First, one of the robotic arm structures 8 is selected based on the size of the automotive part, and its three corresponding motors are driven to activate the movement. The rod 804 can rotate to move the sliding clamp 807 or the conical rubber sleeve 808 to directly above the automotive parts. It can also drive the air pump 817 to extract the gas from the cavity of the first air extraction pipe 805 or the second air extraction pipe 812. As the gas in the first air extraction pipe 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 against the top of the larger automotive parts, so that the larger automotive parts can be transported to the top of the fixed plate 9 by the robotic arm structure 8 and stacked in sequence.

[0045] When the second suction pipe 812 extracts the gas inside the cylindrical groove 806, the gas pressure inside the cylindrical groove 806 gradually decreases, forming a low-pressure environment. As the gas pressure continues to decrease, the sliding block 809 can slide inside the cylindrical groove 806. During the upward movement of the sliding block 809, the fixed block 811 pulls the lever 810 to flip. When the lever 810 flips, the part of it located in the groove 813 inside the inner cavity of the sliding clamp 807 pushes the sliding clamp 807 to achieve a tightening action, which firmly clamps the small parts being gripped, so that the small automotive parts can be transported to the top of the fixed plate 9 by the robotic arm structure 8 and stacked in sequence.

[0046] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
