DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

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

[0040] When in 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 drives the two groups of clamping structures to swing upward. When the two groups of clamping structures swing upward, the magnetic structure drives a group of mounting plates 1 to swing upward synchronously. When the two groups of clamping structures swing to a certain position, the inverter housing 36 is located in the two groups of clamping structures. The inverter housing 36 is positioned by the two groups of clamping structures to ensure the stability of the inverter housing 36. At the same time, the magnetic structure moves the mounting plate 1 to the upper surface of the inverter housing 36. At the same time, one side of the mounting plate 1 is abutted against the upper surface of the inverter housing 36. The welding structure is used to weld the mounting plate 1 to the upper surface of the inverter housing 36, thereby completing the welding of the mounting plate 1, thereby facilitating the rapid positioning of the mounting plate 1 and improving the welding efficiency of the mounting plate 1 and the production efficiency of the inverter.

[0041] When one group of inverter housings 36 completes the welding of the mounting plate 1, the driving structure drives the two groups of clamping structures to swing downward, and the clamping structure drives the magnetic structure to swing downward synchronously when swinging. When the clamping structure swings to a certain position, the magnetic structure corresponds to another group of mounting plates 1 on the feeding structure. The conveying structure continues to drive the next group of inverter housings 36 to move to a specific position, and then the driving structure drives the clamping structure and the magnetic structure to swing upward again, so as to facilitate the welding of the mounting plate 1 for the next group of inverter housings 36, thereby improving processing efficiency and ease of use.

[0042] In order to ensure the stability of the inverter housing 36, for example, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention also includes that the clamping structure includes a horizontal plate 2 arranged above the conveying structure, and the two ends of the horizontal plate 2 are fixedly connected with vertically arranged clamping plates 3, and the two groups of the clamping plates 3 are provided with arc-shaped notches 4 on one side close to the horizontal plate 2, and the lower side of the horizontal plate 2 is fixedly connected with a vertically arranged rotating plate 5, and one side of the rotating plate 5 is fixedly connected with a horizontally arranged driving rod 6, and one end of the driving rod 6 is fixedly connected with a first gear 7, and the first gear 7 is meshed with the driving structure for transmission, and one end of the driving rod 6 away from the first gear 7 is rotatably connected with a vertically arranged first supporting rod 8;

[0043] The clamping plates 3 are each provided with an inclined guide plate 9 on one side away from the horizontal plate 2, and the two groups of guide plates 9 are expanded outward at one end away from the horizontal plate 2. Adjustment structures that can clamp inverter housings 36 of different widths are provided in the two groups of clamping plates 3, and the adjustment structures drive the magnetic attraction structure to move after being squeezed.

[0044] When in 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 is meshed with the first gear 7 to drive the driving 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 guide plate 9, the inverter housing 36 can be easily moved into the two groups of clamping plates 3. The two groups of clamping plates 3 are used to fix the inverter housing 36. When the clamping plates 3 swing upward to a certain position, the adjusting structure contacts the outer side of the inverter housing 36. The adjusting structure further ensures the stability of the inverter housing 36. 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 large, the driving structure drives the clamping plate 3 to swing upward to a certain position. At this time, the adjustment structure is in squeeze contact with the outer side of the inverter housing 36, and the adjustment structure drives the magnetic attraction structure to move synchronously, so as to adjust the position of the mounting plate 1. This facilitates automatic adjustment of the installation position of the mounting plate 1 according to the width of the inverter housing 36, and ensures the stability of the clamping of the inverter housing 36, further improving the convenience of installation and production efficiency.

[0046] When one set of inverter housings 36 completes the welding of the mounting plate 1, the two sets of clamping structures are driven to reset and swing downward by the meshing transmission of the driving structure and the first gear 7. When the two sets of 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, the other set of mounting plates 1 on the feeding structure corresponds to the magnetic attraction structure again, so as to facilitate the subsequent welding of the mounting plate 1 of the next set of inverter housings 36;

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

[0048] For example, Figure 1 , Figure 2 , Figure 4 , Fig.11 , Fig.12 As shown, the present invention also 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 a side of the mounting plate 1 away from the horizontal plate 2, a groove 11 is provided on the lower surface of the moving plate 10, a plurality of groups of magnets 12 are provided in the groove 11, and the magnets 12 are magnetically attracted to the mounting plate 1;

[0049] A first hydraulic telescopic rod 13 is provided on the side away from the two groups of clamping plates 3. The fixed end of the first hydraulic telescopic rod 13 is fixedly connected to one side of the clamping plate 3 through a connecting plate 14. The output end of the first hydraulic telescopic rod 13 is fixedly connected to an L-shaped connecting rod 15. One end of the L-shaped connecting rod 15 is fixedly connected to one side of the movable plate 10. The first hydraulic telescopic rod 13 is connected to the adjustment structure.

[0050] When in use, after 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, and 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, the magnet 12 is magnetically adsorbed with the mounting plate 1 to drive the mounting plate 1 to swing upward synchronously. When the clamping plate 3 swings to a certain position, the inverter housing 36 is squeezed and contacted with the adjustment structure, and the stability of the inverter housing 36 can be ensured by the adjustment structure.

[0051] When the width of the inverter housing 36 is large, the inverter housing 36 squeezes the adjustment structure to move, and is connected with the first hydraulic telescopic rod 13 by the adjustment structure, thereby driving the output end of the first hydraulic telescopic rod 13 to extend, and the output end of the first hydraulic telescopic rod 13 drives the L-shaped connecting rod 15 and the moving plate 10 to move synchronously, and the moving plate 10 drives the mounting plate 1 to move synchronously when moving, so as to automatically adjust the position of the mounting plate 1 according to the width of the inverter, thereby improving processing efficiency and convenience of use;

[0052] When one group of inverter housings 36 completes the welding of the mounting plate 1, the driving structure meshes with the first gear 7 to drive the two groups of clamping structures to reset and swing downward. When the two groups of clamping plates 3 swing downward to the initial position, the next group of mounting plates 1 on the feeding structure correspond to the slots 11 of the movable plate 10, and the magnets 12 are magnetically adsorbed with the next group of mounting plates 1, thereby facilitating the subsequent movement of the next group of mounting plates 1 and facilitating the welding of the mounting plates 1 of the next group of inverter housings 36.

[0053] For example, Figure 4 , Fig.11 , Fig.12 As shown, the present invention also includes that the adjustment structure includes an extrusion plate 16 vertically arranged between the two groups of clamping plates 3, a second hydraulic telescopic rod 17 is fixedly connected between the extrusion 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 extrusion plate 16, and the fixed end of the second hydraulic telescopic rod 17 is connected to 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 extrusion plate 16 and the cross plate 2.

[0054] When in use, when the width of the inverter housing 36 is large, the inverter housing 36 is squeezed and contacted with one side of the squeezing plate 16, and the squeezing plate 16 can ensure the stability of the inverter housing 36, and at the same time drive the squeezing plate 16 to move. When the squeezing plate 16 moves, it squeezes the second hydraulic telescopic rod 17 and drives the return spring 18 to store force. The second hydraulic telescopic rod 17 is connected with the first hydraulic telescopic rod 13 through a pipeline, thereby driving the output end of the first hydraulic telescopic rod 13 to extend, thereby driving 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 the automatic adjustment of 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 convenience of use;

[0055] When the welding of one group of inverter housings 36 is completed, the driving structure drives the clamping plate 3 to reset and swing downward. At this time, the reset spring 18 drives 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 movable plate 10 to reset and move synchronously, so as to facilitate the subsequent welding of the mounting plate 1 for the next group of inverter housings 36.

[0056] In order to facilitate the swinging of the clamping plate 3, for example, Figure 1 , Figure 3 , Figure 5 , Figure 7 , Fig. 9 As shown, the present invention also includes that the driving structure includes a double-axis motor 19 horizontally arranged below the conveying structure, the output ends of the double-axis motor 19 are fixedly connected to a horizontally arranged first worm 20, the first worm 20 is located below the first gear 7 and meshes with the first gear 7 for transmission, a vertically arranged second support rod 21 is fixedly connected below the double-axis motor 19, one end of the driving rod 6 away from the first support rod 8 is rotatably connected to a fixed rod 22, and one end of the fixed rod 22 is fixedly connected to one side of the second support rod 21;

[0057] The output ends of the dual-axis motor 19 are both rotatably connected to a vertically arranged third support rod 23 .

[0058] When in use, after the conveying structure drives the inverter housing 36 to move to a specific position, the dual-axis motor 19 is turned on, and the dual-axis motor 19 drives the first worm 20 to rotate. When the first worm 20 rotates, it meshes with the first gear 7 for transmission, thereby driving the first gear 7 to rotate. When the first gear 7 rotates, it drives the driving rod 6, the rotating plate 5, the horizontal plate 2, and the clamping plate 3 to swing upward, so as to facilitate clamping the inverter housing 36. At the same time, the moving plate 10 drives the mounting plate 1 to move to the upper surface of the inverter housing 36, thereby improving the installation convenience of the mounting plate 1.

[0059] The second support rod 21 can ensure the stability of the dual-axis motor 19 , the fixing rod 22 can further ensure the stability of the driving rod 6 , and the third support rod 23 can further ensure the rotation stability of the dual-axis motor 19 .

[0060] In order to facilitate the subsequent welding of the mounting plate 1 for the next set of inverter housings 36, for example, Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the present invention also includes that the feeding structure includes a plurality of groups of conveying rollers 24 horizontally and symmetrically arranged on both sides of the conveying structure, both ends of the conveying rollers 24 are rotatably connected to vertically arranged first supporting legs 25, a plurality of groups of conveying rollers 24 are provided with conveyor belts 26 on the outside, a plurality of groups of symmetrically arranged clamping blocks 27 are fixedly connected to the outside of the conveyor belts 26, a positioning groove 28 is provided on one side of the clamping block 27, the mounting plate 1 is installed between the two groups of clamping blocks 27 through the positioning groove 28, and a plurality of groups of mounting holes 29 are provided on the mounting plate 1;

[0061] A transmission structure for driving the conveyor belt 26 to move is provided on one side of the conveying roller 24 .

[0062] When in use, when the dual-axis motor 19 drives the two groups of clamping structures to swing upward, the transmission structure drives the conveying roller 24 to rotate, and when the conveying roller 24 rotates, it drives the conveyor belt 26 to move. When the conveyor belt 26 moves, it drives several groups of mounting plates 1 to move synchronously by relying on the clamping block 27. When the two groups of clamping plates 3 swing upward, a group of mounting plates 1 on the conveyor belt 26 corresponds to the moving trajectory of the moving plate 10. When the dual-axis motor 19 drives the moving plate 10 to swing, the mounting plate 1 can be inserted into the slot 11, and at the same time, it relies on the magnet 12 to magnetically adsorb with the corresponding group of mounting plates 1, so as to facilitate the subsequent welding of the mounting plate 1 to the next group of inverter housings 36;

[0063] The vertical stability of the mounting plate 1 can be ensured by the action of the clamping block 27 and the positioning groove 28, so that after the movable plate 10 swings downward, the mounting plate 1 corresponds to the groove 11 of the movable plate 10;

[0064] After the mounting plate 1 and the inverter housing 36 are welded, the inverter housing 36 can be easily installed later by relying on the mounting holes 29 , thereby ensuring the stability of the inverter housing 36 after installation.

[0065] In order to facilitate the movement of several groups of mounting plates 1, for example, Figure 5 , Figure 6As shown, the present invention also includes that the transmission structure includes a second gear 30 vertically arranged on one side of the first supporting leg 25, a transmission shaft is fixedly connected to one side of the second gear 30, an end of the transmission shaft away from the second gear 30 passes through the first supporting leg 25 and is fixedly connected to one end of a group of conveying rollers 24, and a one-way bearing is connected between the conveying roller 24 and the transmission shaft;

[0066] The third support rod 23 is provided with an inclined rotating shaft 31 on the side away from the dual-axis motor 19, and the end of the rotating shaft 31 away from the third support rod 23 is fixedly connected to the second worm 32, and the second worm 32 is meshed with the second gear 30 for transmission. One end of the rotating shaft 31 is fixedly connected to the output end of the dual-axis motor 19 through a universal coupling 33, and the end of the rotating shaft 31 away from the third support rod 23 is rotatably connected to a vertically arranged fourth support rod 34.

[0067] When in use, when the next set of inverter housings 36 needs to be welded with the mounting plate 1, the dual-axis motor 19 drives the two sets of clamping structures to swing upward, and the dual-axis motor 19 and the universal coupling 33 drive the rotating shaft 31 to rotate. When the rotating shaft 31 rotates, it drives the second worm 32 to rotate and mesh with the second gear 30 for transmission, and the second gear 30 and the one-way bearing drive the transmission shaft and a set of conveying rollers 24 to rotate. When the conveying rollers 24 rotate, it drives the conveyor belt 26 to move, so as to facilitate the movement of several sets of mounting plates 1; when the two sets of clamping plates 3 swing downward to the initial position, at this time, a set of mounting plates 1 on the conveyor belt 26 corresponds to the slot 11 of the movable plate 10, and at the same time, the magnet 12 is magnetically adsorbed with the corresponding set of mounting plates 1, so as to facilitate the subsequent welding of the mounting plates 1 of the next set of inverter housings 36;

[0068] When the dual-axis motor 19 drives the clamping plate 3 to swing downward, the second worm 32 is meshed with the second gear 30 for transmission. At this time, relying on the effect 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 is meshed with the second gear 30 for transmission. At this time, relying on the effect of the one-way bearing, the transmission shaft and the conveying roller 24 are driven to rotate, and thereby the mounting plate 1 is driven to move, ensuring that after the clamping plate 3 swings downward, a group of mounting plates 1 on the conveyor belt 26 correspond to the slots 11 of the movable plate 10.

[0069] For example, Figure 1 As shown, the present invention also includes that the conveying structure includes a horizontally arranged electric conveyor belt 35, a plurality of groups of vertically arranged second supporting legs 40 are arranged on the outer side of the electric conveyor belt 35, and a plurality of groups of inverter housings 36 are arranged on the electric conveyor belt 35.

[0070] When in use, the inverter housing 36 can be driven to move by the electric conveyor belt 35 , and the stability of the electric conveyor belt 35 can be ensured by the second supporting legs 40 .

[0071] For example, Figure 5 , Fig. 9 As shown, the present invention also includes that the welding structure includes a base 37 , a mechanical arm 38 is provided above the base 37 , and a welding gun 39 is provided at one end of the mechanical arm 38 .

[0072] During use, after the electric conveyor belt 35 drives the inverter housing 36 to move to a specific position, the clamping plate 3 is swung upward so that the inverter housing 36 is located on the inner side of the clamping plate 3, and at the same time, the extrusion plate 16 contacts the outer side of the inverter housing 36. The stability of the inverter housing 36 is further guaranteed by the extrusion plate 16. 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 welding gun 39 is driven to move by the mechanical arm 38, and the mounting plate 1 is welded to the upper surface of the inverter housing 36 by the welding gun 39, thereby improving the welding efficiency of the mounting plate 1 and the production efficiency of the inverter; the stability of the mechanical arm 38 can be guaranteed by the base 37.

[0073] When the present invention is in use, the electric conveyor belt 35 is driven to drive the inverter housing 36 to move. When the inverter housing 36 moves to a specific position, the double-axis motor 19 is turned on, and the double-axis motor 19 is used to drive the first worm 20 to rotate. When the first worm 20 rotates, it meshes with the first gear 7 for transmission, thereby driving the first gear 7 to rotate. When the first gear 7 rotates, it drives the driving 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 guide plate 9, the inverter housing 36 can be easily moved into the two groups of clamping plates 3. Relying on the two groups of clamping plates 3, it is convenient to fix the inverter housing 36. When the clamping plates 3 swing upward to a certain position, the inverter The housing 36 is in extrusion contact with one side of the extrusion plate 16. The extrusion plate 16 can ensure the stability of the inverter housing 36 and drive the extrusion plate 16 to move. When the extrusion plate 16 moves, it squeezes the second hydraulic telescopic rod 17 and drives the return spring 18 to store force. The second hydraulic telescopic rod 17 is connected with the first hydraulic telescopic rod 13 through a pipeline, thereby driving the output end of the first hydraulic telescopic rod 13 to extend, thereby driving 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 the automatic adjustment of 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, thereby improving the processing efficiency and convenience of use;

[0074] When the dual-axis motor 19 drives the two groups of clamping structures to swing upward, the dual-axis motor 19 and the universal coupling 33 drive the rotating shaft 31 to rotate. When the rotating shaft 31 rotates, it drives the second worm 32 to rotate and mesh with the second gear 30 for transmission. The second gear 30 and the one-way bearing drive the transmission shaft and a group of conveying rollers 24 to rotate. When the conveying rollers 24 rotate, they drive the conveyor belt 26 to move, so as to facilitate the movement of several groups of mounting plates 1.

[0075] After the inverter housing 36 is clamped and fixed, the mechanical arm 38 drives the welding gun 39 to move, and the welding gun 39 is used to weld the mounting plate 1 to the upper surface of the inverter housing 36, thereby improving the welding efficiency of the mounting plate 1 and the production efficiency of the inverter;

[0076] When one set of inverter housings 36 completes the welding of the mounting plate 1, the first worm 20 and the first gear 7 mesh with each other to drive the two sets of clamping structures to reset and swing downward. When the two sets of clamping plates 3 swing downward to the initial position, the next set of mounting plates 1 on the conveyor belt 26 correspond to the slots 11 of the movable plate 10, and the magnets 12 are magnetically adsorbed with the next set of mounting plates 1, so as to facilitate the subsequent movement of the next set of mounting plates 1 and facilitate the welding of the mounting plates 1 of the next set of inverter housings 36.

[0077] The double-axis motor 19 drives the clamping plate 3 to reset and swing downward, and the reset spring 18 drives the extrusion plate 16 to reset, so that the second hydraulic telescopic rod 17 is extended, and 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 the subsequent welding of the mounting plate 1 on the next set of inverter housings 36;

[0078] When the dual-axis motor 19 drives the clamping plate 3 to swing downward, the second worm 32 is meshed with the second gear 30 for transmission. At this time, relying on the effect 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 is meshed with the second gear 30 for transmission. At this time, relying on the effect of the one-way bearing, the transmission shaft and the conveying roller 24 are driven to rotate, and thereby the mounting plate 1 is driven to move, ensuring that after the clamping plate 3 swings downward, a group of mounting plates 1 on the conveyor belt 26 correspond to the slots 11 of the movable plate 10.
