Technical Field

[0001] The present invention relates to the technical field of inverter welding, and particularly relates to an automatic welding device for photovoltaic inverter production. Background Art

[0002] When an inverter is produced, it is necessary to weld the mounting plate to the inverter housing. After welding, it is convenient for subsequent installation of the inverter. Currently, when welding the mounting plate, most of the time, the mounting plate is manually abutted against the outside of the inverter housing and then the welding operation is carried out. This processing method has low efficiency and requires manual positioning of the mounting plate. Therefore, an automatic welding device for photovoltaic inverter production is proposed to facilitate quick positioning of the mounting plate, improve the welding efficiency of the mounting plate and the production efficiency of the inverter. Summary of the Invention

[0003] Aiming at the problems in the prior art, the present invention provides an automatic welding device for photovoltaic inverter production to facilitate quick positioning of the mounting plate, improve the welding efficiency of the mounting plate and the production efficiency of the inverter.

[0004] The technical solution adopted by the present invention to solve its technical problems is an automatic welding device for photovoltaic inverter production, including a conveying structure for conveying the inverter housing. On both sides of the conveying structure, there are symmetrically arranged clamping structures for positioning the inverter housing. Below the conveying structure, there is a driving structure for driving the clamping structures to swing. On the outside of the conveying structure, there are feeding structures for conveying the mounting plates. On the feeding structures, there are several groups of vertically arranged mounting plates. On the clamping structures, there are magnetic attraction structures. After the clamping structures swing, the magnetic attraction structures correspond to a group of mounting plates. On one side of the conveying structure, there is a welding structure.

[0005] Specifically, each clamping structure includes a cross plate arranged above the conveying structure. At both ends of the cross plate, there are vertically connected clamping plates. On one side of the two clamping plates close to the cross plate, there are arc-shaped notches. Below the cross plate, there is a vertically connected rotating plate. On one side of the rotating plate, there is a horizontally connected driving rod. At one end of the driving rod, there is a first gear which is meshed and driven by the driving structure. At the end of the driving rod far from the first gear, there is a vertically connected first support rod.

[0006] On the side of each clamping plate far from the cross plate, there are inclined guide plates. The ends of the two guide plates far from the cross plate expand outwards. Inside the two clamping plates, there is an adjusting structure that can clamp inverter housings of different widths. After being squeezed, the adjusting structure drives the magnetic attraction structure to move.

[0007] Specifically, the magnetic attraction structure includes a moving plate arranged above the mounting plate. In the initial state, the moving plate is located above one side of the mounting plate away from the cross plate.

When the pressing plate moves, it presses the second hydraulic telescopic rod and drives the return springs to store energy. By relying on the fact that the second hydraulic telescopic rod is communicated with the first hydraulic telescopic rod through a pipeline, the output end of the first hydraulic telescopic rod is driven to extend, thereby driving the moving plate to move. When the moving plate moves, it drives the mounting plate to move synchronously, so as to automatically adjust the position of the mounting plate according to the width of the inverter, and at the same time ensure the stability of the inverter housing, improve the processing efficiency and the use convenience;

[0016] Specifically, the transmission structure includes a second gear vertically arranged on one side of the first support leg. A transmission shaft is fixedly connected to one side of the second gear. The end of the transmission shaft away from the second gear passes through the first support leg and is fixedly connected to one end of a group of the conveying rollers.

Specific Embodiments

[0038] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0039] In order to facilitate the rapid positioning of the mounting plate parts, improve the welding efficiency of the mounting plate parts and the production efficiency of the inverter, as an embodiment of the present invention, as Figure 1 shown, an automatic welding device for photovoltaic inverter production described in the present invention includes a conveying structure for conveying the inverter housing 36, clamping structures symmetrically arranged on both sides of the conveying structure for positioning the inverter housing 36, a driving structure for driving the clamping structures to swing below the conveying structure, feeding structures for conveying the mounting plates 1 arranged on the outer sides of the conveying structure, a plurality of groups of vertically arranged mounting plates 1 provided on the feeding structures, magnetic attraction structures provided on the clamping structures, the magnetic attraction structures corresponding to a group of mounting plates 1 after the clamping structures swing, and a welding structure provided on one side of the conveying structure.

[0040] During use, the inverter housing 36 is driven to move by the conveying structure. After the inverter housing 36 moves to a specific position, the two clamping structures are driven to swing upward by the driving structure. When the two clamping structures swing upward, a magnetic attraction structure drives a mounting plate 1 to swing upward synchronously. When the two clamping structures swing to a certain position, at this time the inverter housing 36 is located within the two clamping structures, and the two clamping structures are relied on to position the inverter housing 36 to ensure the stability of the inverter housing 36. At the same time, the magnetic attraction structure moves the mounting plate 1 to the upper surface of the inverter housing 36, and one side of the mounting plate 1 abuts against the upper surface of the inverter housing 36. The mounting plate 1 is welded to the upper surface of the inverter housing 36 by the welding structure, thereby completing the welding of the mounting plate 1, so as to facilitate the rapid positioning of the mounting plate 1 and improve the welding efficiency of the mounting plate 1 and the production efficiency of the inverter;

[0041] After the welding of the mounting plate 1 is completed for a group of inverter housings 36, the driving structure drives the two clamping structures to swing downward. When the clamping structures swing, the magnetic attraction structure is driven to swing downward synchronously. When the clamping structures swing to a certain position, at this time the magnetic attraction structure corresponds to another mounting plate 1 on the feeding structure. After the conveying structure continues to drive the next group of inverter housings 36 to move to a specific position, the driving structure is relied on again to drive the clamping structures and the magnetic attraction structure to swing upward, so as to facilitate the welding of the mounting plate 1 for the next group of inverter housings 36 and improve the processing efficiency and use convenience.

[0042] To ensure the stability of the inverter housing 36, by way of example, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown, the present invention further includes that the clamping structures each include a cross plate 2 disposed above the conveying structure. Both ends of the cross plate 2 are fixedly connected with vertically arranged clamping plates 3. An arc-shaped notch 4 is provided on one side of each of the two clamping plates 3 close to the cross plate 2. A vertically arranged rotating plate 5 is fixedly connected to the lower side of the cross plate 2. A horizontally arranged driving rod 6 is fixedly connected to one side of the rotating plate 5. One end of the driving rod 6 is fixedly connected with a first gear 7, and the first gear 7 is in meshing transmission with the driving structure. The end of the driving rod 6 far from the first gear 7 is rotatably connected with a vertically arranged first support rod 8;

[0043] An inclined guide plate 9 is provided on one side of each of the clamping plates 3 far from the cross plate 2. The ends of the two guide plates 9 far from the cross plate 2 expand outwards. An adjusting structure capable of clamping inverter housings 36 of different widths is provided within the two clamping plates 3, and the adjusting structure drives the magnetic attraction structure to move after being squeezed.

[0044] During use, the inverter housing 36 is driven to move by the conveying structure. When the inverter housing 36 moves to a specific position, the driving structure meshes with the first gear 7 to drive the rod 6 to rotate. When the driving rod 6 rotates, it drives the rotating plate 5, the cross plate 2, and the clamping plate 3 to swing upward. Relying on the guiding effect of the guiding plate 9, it is convenient to move the inverter housing 36 into the two clamping plates 3. The two clamping plates 3 are used to fix the inverter housing 36. When the clamping plate 3 swings upward to a certain position, the adjusting structure contacts the outer side of the inverter housing 36. Relying on the adjusting structure, the stability of the inverter housing 36 is further ensured. At the same time, the mounting plate 1 on the magnetic attraction structure contacts one side of the inverter housing 36. The mounting plate 1 is welded to the upper surface of the inverter housing 36 by the welding structure, thereby improving the welding efficiency of the mounting plate 1 and the production efficiency of the inverter;

[0045] When the width of the inverter housing 36 is relatively large, after the driving structure drives the clamping plate 3 to swing upward to a certain position, the adjusting structure contacts and presses against the outer side of the inverter housing 36. Relying on the adjusting structure, the magnetic attraction structure is driven to move synchronously, thereby adjusting the position of the mounting plate 1. In this way, it is convenient to automatically adjust the mounting position of the mounting plate 1 according to the width of the inverter housing 36 and ensure the stability of the clamping of the inverter housing 36, further improving the installation convenience and production efficiency;

[0046] After the welding of the mounting plate 1 is completed for one inverter housing 36, the driving structure meshes with the first gear 7 to drive the two clamping structures to swing downward and reset. When the two clamping plates 3 swing downward to the initial position, one side of the feeding structure is located in the arc-shaped notch 4, and at the same time, another mounting plate 1 on the feeding structure corresponds to the magnetic attraction structure again, thereby facilitating the subsequent welding of the mounting plate 1 for the next inverter housing 36;

[0047] The stability of the driving rod 6 can be ensured by relying on the first support rod 8.

[0048] Exemplarily, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 11 、 Figure 12 shown, the present invention further includes that the magnetic attraction structure includes a moving plate 10 arranged above the mounting plate 1. The moving plate 10 is initially located above the side of the mounting plate 1 away from the cross plate 2. A slot 11 is provided on the lower surface of the moving plate 10, and a plurality of groups of magnets 12 are arranged in the slot 11. The magnets 12 are magnetically adsorbed to the mounting plate 1;

[0049] On the sides of both groups of the clamping plates 3 away from each other, first hydraulic telescopic rods 13 are provided. The fixed ends of the first hydraulic telescopic rods 13 are fixedly connected to one side of the clamping plates 3 through connecting plates 14. The output ends of the first hydraulic telescopic rods 13 are fixedly connected with L-shaped connecting rods 15. One end of the L-shaped connecting rods 15 is fixedly connected to one side of the moving plate 10. The first hydraulic telescopic rods 13 are communicated with the adjusting structure.

[0050] During use, when the conveying structure drives the inverter housing 36 to move to a specific position, the driving structure drives the clamping plate 3 to swing upward. When the clamping plate 3 swings upward, it drives the connecting plate 14, the first hydraulic telescopic rod 13, the L-shaped connecting rod 15, and the moving plate 10 to swing upward synchronously. When the moving plate 10 swings upward, relying on the magnetic adsorption between the magnet 12 and the mounting plate 1, the mounting plate 1 is driven to swing upward synchronously. When the clamping plate 3 swings to a certain position, the inverter housing 36 is in pressing contact with the adjusting structure. Relying on the adjusting structure, the stability of the inverter housing 36 can be ensured.

[0051] When the width of the inverter housing 36 is relatively large, the inverter housing 36 presses the adjusting structure to move. Relying on the connection between the adjusting structure and the first hydraulic telescopic rod 13, the output end of the first hydraulic telescopic rod 13 is driven to extend. Relying on the output end of the first hydraulic telescopic rod 13 to drive the L-shaped connecting rod 15 and the moving plate 10 to move synchronously. When the moving plate 10 moves, it drives the mounting plate 1 to move synchronously, so as to automatically adjust the position of the mounting plate 1 according to the width of the inverter, improving the processing efficiency and the convenience of use.

[0052] When the welding of the mounting plate 1 for one group of inverter housings 36 is completed, the driving structure drives the two groups of clamping structures to swing downward and reset by meshing and driving with the first gear 7. When the two groups of clamping plates 3 swing downward to the initial position, at this time, the next mounting plate 1 on the feeding structure corresponds to the slot 11 of the moving plate 10. Relying on the magnetic adsorption between the magnet 12 and the next mounting plate 1, it is convenient to drive the next mounting plate 1 to move subsequently, and at the same time, it is convenient to weld the mounting plate 1 for the next group of inverter housings 36.

[0053] Exemplarily, such as Figure 4 、 Figure 11 、 Figure 12 shown, the present invention further includes that the adjusting structure includes a pressing plate 16 vertically arranged between the two groups of clamping plates 3. A second hydraulic telescopic rod 17 is fixedly connected between the pressing plate 16 and the cross plate 2. The fixed end of the second hydraulic telescopic rod 17 is fixedly connected to one side of the cross plate 2. The output end of the second hydraulic telescopic rod 17 is fixedly connected to one side of the pressing plate 16. The fixed end of the second hydraulic telescopic rod 17 is communicated with the fixed end of the first hydraulic telescopic rod 13 through a pipeline; a plurality of groups of return springs 18 are fixedly connected between the pressing plate 16 and the cross plate 2.

[0054] During use, when the width of the inverter housing 36 is relatively large, the inverter housing 36 is in extrusion contact with one side of the extrusion plate 16. Relying on the extrusion plate 16 can ensure the stability of the inverter housing 36, and at the same time drive the extrusion plate 16 to move. When the extrusion plate 16 moves, it extrudes the second hydraulic telescopic rod 17 and drives the return spring 18 to store energy. Relying on the second hydraulic telescopic rod 17 to communicate with the first hydraulic telescopic rod 13 through a pipeline, thereby driving the output end of the first hydraulic telescopic rod 13 to extend, so as to drive the moving plate 10 to move. When the moving plate 10 moves, it drives the mounting plate 1 to move synchronously, so as to facilitate automatically adjusting the position of the mounting plate 1 according to the width of the inverter, and at the same time ensure the stability of the inverter housing 36, improve the processing efficiency and the convenience of use;

[0055] After a group of inverter housings 36 are welded, rely on the driving structure to drive the clamping plate 3 to swing downward to reset. At this time, rely on the return spring 18 to drive the extrusion plate 16 to reset, the second hydraulic telescopic rod 17 extends, and the output end of the first hydraulic telescopic rod 13 drives the L-shaped connecting rod 15 and the moving plate 10 to reset and move synchronously, so as to facilitate welding the mounting plate 1 for the next group of inverter housings 36 later.

[0056] For the convenience of driving the clamping plate 3 to swing, by way of example, as Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 9 shown, the present invention further includes that the driving structure includes a double-shaft motor 19 horizontally arranged below the conveying structure. The output ends of the double-shaft motor 19 are fixedly connected with horizontally arranged first worms 20. The first worms 20 are located below the first gear 7 and are in meshing transmission with the first gear 7. A vertically arranged second support rod 21 is fixedly connected below the double-shaft motor 19. One end of the driving rod 6 away from the first support rod 8 is rotatably connected with a fixed rod 22. One end of the fixed rod 22 is fixedly connected with one side of the second support rod 21;

[0057] The output ends of the double-shaft motor 19 are rotatably connected with vertically arranged third support rods 23.

[0058] During use, when the conveying structure drives the inverter housing 36 to move to a specific position, turn on the double-shaft motor 19. Rely on the double-shaft motor 19 to drive the first worm 20 to rotate. When the first worm 20 rotates, it is in meshing transmission with the first gear 7, thereby driving the first gear 7 to rotate. When the first gear 7 rotates, it drives the rod 6, the rotating plate 5, the cross plate 2, and the clamping plate 3 to swing upward, so as to facilitate clamping the inverter housing 36. At the same time, rely on the moving plate 10 to drive the mounting plate 1 to move to the upper surface of the inverter housing 36, improving the installation convenience of the mounting plate 1;

[0059] Relying on the second support rod 21 can ensure the stability of the dual-axis motor 19. Relying on the fixed rod 22 can further ensure the stability of the driving rod 6. Relying on the third support rod 23 can further ensure the rotational stability of the dual-axis motor 19.

[0060] For the convenience of subsequent welding of the mounting plate 1 to the next group of inverter housings 36, exemplarily, as Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 shown, the present invention further includes that the feeding structure includes a plurality of groups of conveying rollers 24 horizontally symmetrically arranged on both sides of the conveying structure. Both ends of the conveying rollers 24 are rotatably connected to vertically arranged first support legs 25. A conveyor belt 26 is arranged outside the plurality of groups of conveying rollers 24. A plurality of groups of symmetrically arranged clamping blocks 27 are fixedly connected to the outside of the conveyor belt 26. A positioning groove 28 is arranged on one side of the clamping block 27. The mounting plate 1 is installed between two clamping blocks 27 through the positioning groove 28. A plurality of mounting holes 29 are arranged on the mounting plate 1;

[0062] During use, when the dual-axis motor 19 drives the two clamping structures to swing upward, the transmission structure drives the conveying rollers 24 to rotate. When the conveying rollers 24 rotate, they drive the conveyor belt 26 to move. When the conveyor belt 26 moves, it drives a plurality of mounting plates 1 to move synchronously by relying on the clamping blocks 27. After the two clamping plates 3 swing upward, at this time, a mounting plate 1 on the conveyor belt 26 corresponds to the movement trajectory of the moving plate 10. When the dual-axis motor 19 drives the moving plate 10 to swing later, the mounting plate 1 can be snapped into the slot 11, and at the same time, it is magnetically adsorbed to a corresponding mounting plate 1 by relying on the magnet 12, so as to facilitate subsequent welding of the mounting plate 1 to the next group of inverter housings 36;

[0063] Relying on the action of the clamping block 27 and the positioning groove 28 can ensure the vertical stability of the mounting plate 1, facilitating the mounting plate 1 to correspond to the slot 11 of the moving plate 10 after the moving plate 10 swings downward;

[0064] After the mounting plate 1 is welded to the inverter housing 36, relying on the mounting holes 29 can facilitate subsequent installation of the inverter housing 36 and ensure the stability of the inverter housing 36 after installation.

[0065] For the convenience of driving a plurality of mounting plates 1 to move, exemplarily, as Figure 5 、 Figure 6As shown, the present invention further includes that the transmission structure includes a second gear 30 vertically arranged on one side of the first support leg 25.

The end of the rotating shaft 31 away from the third support rod 23 is rotatably connected with a vertically arranged fourth support rod 34.

[0067] During use, when the next group of inverter housings 36 need to be welded to the mounting plate 1, the dual-axis motor 19 drives the two clamping structures to swing upward. Relying on the dual-axis motor 19 and the universal coupling 33, the rotating shaft 31 is driven to rotate. When the rotating shaft 31 rotates, it drives the second worm 32 to rotate and mesh with the second gear 30. Relying on the second gear 30 and the one-way bearing, the transmission shaft and a group of conveying rollers 24 are driven to rotate. When the conveying rollers 24 rotate, the conveyor belt 26 is driven to move, so as to drive a number of mounting plates 1 to move; when the two clamping plates 3 swing downward to the initial position, at this time, a mounting plate 1 on the conveyor belt 26 corresponds to the slot 11 of the moving plate 10, and at the same time, relying on the magnetic attraction of the magnet 12 and the corresponding group of mounting plates 1, it is convenient for subsequent welding of the mounting plate 1 to the next group of inverter housings 36;

[0068] When the dual-axis motor 19 drives the clamping plate 3 to swing downward, the second worm 32 meshes with the second gear 30. At this time, due to the function of the one-way bearing, the conveying roller 24 is no longer driven to rotate; when the dual-axis motor 19 drives the clamping plate 3 to swing upward, the second worm 32 meshes with the second gear 30. At this time, relying on the function of the one-way bearing, the transmission shaft and the conveying roller 24 are driven to rotate, and the mounting plate 1 is driven to move accordingly, ensuring that after the clamping plate 3 swings downward, a mounting plate 1 on the conveyor belt 26 corresponds to the slot 11 of the moving plate 10.

[0069] Exemplarily, as Figure 1 shown, the present invention further includes that the conveying structure includes a horizontally arranged electric conveyor belt 35. There are several groups of vertically arranged second support legs 40 outside the electric conveyor belt 35. There are several groups of inverter housings 36 on the electric conveyor belt 35.

[0070] During use, the electric conveyor belt 35 is relied on to facilitate the movement of the inverter housing 36, and at the same time, the second support leg 40 can ensure the stability of the electric conveyor belt 35.

[0071] Exemplarily, as Figure 5 , Figure 9 shown, the present invention further includes that the welding structure includes a base 37, a robotic arm 38 is provided above the base 37, and a welding torch 39 is provided at one end of the robotic arm 38.

[0072] During use, when the electric conveyor belt 35 drives the inverter housing 36 to move to a specific position, the clamping plate 3 is relied on to swing upward, so that the inverter housing 36 is located inside the clamping plate 3. At the same time, the pressing plate 16 contacts the outer side of the inverter housing 36. The pressing plate 16 is relied on to further ensure the stability of the inverter housing 36. At the same time, the mounting plate 1 on the moving plate 10 contacts one side of the inverter housing 36. At this time, the robotic arm 38 is relied on to drive the welding torch 39 to move, and the mounting plate 1 is welded to the upper surface of the inverter housing 36 by the welding torch 39, so as to improve the welding efficiency of the mounting plate 1 and the production efficiency of the inverter; the base 37 can ensure the stability of the robotic arm 38.

[0073] When the present invention is in use, the electric conveyor belt 35 is relied on to facilitate the movement of the inverter housing 36. When the inverter housing 36 moves to a specific position, the double-shaft motor 19 is turned on. The double-shaft motor 19 is relied on to drive the first worm 20 to rotate. When the first worm 20 rotates, it meshes with and drives the first gear 7, thereby driving the first gear 7 to rotate. When the first gear 7 rotates, it drives the rod 6, the rotating plate 5, the cross plate 2, and the clamping plate 3 to swing upward. Relying on the guiding effect of the guiding plate 9, the inverter housing 36 can be conveniently moved into the two clamping plates 3. The two clamping plates 3 are relied on to facilitate the fixing of the inverter housing 36. When the clamping plate 3 swings upward to a certain position, the inverter housing 36 is in pressing contact with one side of the pressing plate 16. The pressing plate 16 can ensure the stability of the inverter housing 36 and drive the pressing plate 16 to move at the same time. When the pressing plate 16 moves, it presses the second hydraulic telescopic rod 17 and drives the return spring 18 to store energy at the same time. The second hydraulic telescopic rod 17 is connected to the first hydraulic telescopic rod 13 through a pipeline, thereby driving the output end of the first hydraulic telescopic rod 13 to extend, so as to drive the moving plate 10 to move. When the moving plate 10 moves, it drives the mounting plate 1 to move synchronously, so as to conveniently automatically adjust the position of the mounting plate 1 according to the width of the inverter, and at the same time ensure the stability of the inverter housing 36, improve the processing efficiency and the use convenience;

[0074] When the biaxial motor 19 drives the two groups of clamping structures to swing upward, the rotation shaft 31 is driven to rotate by relying on the biaxial motor 19 and the universal coupling 33. When the rotation shaft 31 rotates, the second worm 32 is driven to rotate and meshes with the second gear 30 for transmission. The transmission shaft and a group of conveying rollers 24 are driven to rotate by relying on the second gear 30 and the one-way bearing. When the conveying rollers 24 rotate, the conveyor belt 26 is driven to move, so as to facilitate driving several groups of mounting plates 1 to move;

[0075] After the inverter housing 36 is clamped and fixed, the welding torch 39 is driven to move by relying on the robotic arm 38. The mounting plate 1 is welded to the upper surface of the inverter housing 36 by relying on the welding torch 39, so as to improve the welding efficiency of the mounting plate 1 and the production efficiency of the inverter;

[0076] After a group of inverter housings 36 complete the welding of the mounting plate 1, the two groups of clamping structures are driven to swing downward and reset by relying on the meshing transmission of the first worm 20 and the first gear 7. When the two clamping plates 3 swing downward to the initial position, at this time, the next mounting plate 1 on the conveyor belt 26 corresponds to the slot 11 of the moving plate 10. The next mounting plate 1 is magnetically adsorbed by relying on the magnet 12, so as to facilitate driving the next mounting plate 1 to move subsequently, and at the same time facilitate welding the mounting plate 1 to the next inverter housing 36;

[0077] The biaxial motor 19 is relied on to drive the clamping plate 3 to swing downward and reset. At this time, the extrusion plate 16 is driven to reset by relying on the reset spring 18, so that the second hydraulic telescopic rod 17 extends. At the same time, the output end of the first hydraulic telescopic rod 13 drives the L-shaped connecting rod 15 and the moving plate 10 to reset and move synchronously, so as to facilitate welding the mounting plate 1 to the next inverter housing 36 subsequently;

[0078] When the biaxial motor 19 drives the clamping plate 3 to swing downward, the second worm 32 meshes with the second gear 30 for transmission. At this time, relying on the function of the one-way bearing, the conveying roller 24 is no longer driven to rotate; when the biaxial motor 19 drives the clamping plate 3 to swing upward, the second worm 32 meshes with the second gear 30 for transmission. At this time, relying on the function of the one-way bearing, the transmission shaft and the conveying roller 24 are driven to rotate, and the mounting plate 1 is driven to move accordingly, ensuring that after the clamping plate 3 swings downward, at this time, a group of mounting plates 1 on the conveyor belt 26 corresponds to the slot 11 of the moving plate 10.
