Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic assembly welding, in particular to photovoltaic assembly automatic welding and processing integrated equipment. Background Art

[0002] At present, with the rapid growth of global demand for renewable energy, the photovoltaic power generation industry is booming at an unprecedented rate. In this context, improving production efficiency and product quality has become the key for photovoltaic companies to win the market. As the core component of the photovoltaic system, every step in the manufacturing process of solar cells is crucial, especially the precise and efficient welding of multiple cells together to form a series structure that can generate sufficient current. This link is directly related to the performance and life of photovoltaic modules.

[0003] In the process of manufacturing battery cells in series, welding busbars (welding strips) to battery cells is an indispensable step. As a channel for collecting and transmitting current, the welding quality of busbars directly determines the current transmission efficiency and system stability. However, in the traditional operation mode, this step depends on the manual operation skills and long-term accumulated experience of workers. This requires not only superb operation skills, but also the ability to accurately control welding parameters, which undoubtedly greatly increases labor costs and limits production levels.

[0004] Due to the large number of uncontrollable factors in manual operation, a series of quality problems often occur, such as welding deviation (the welding ribbon is not accurately aligned with the battery cell electrode), cold welding (the welding is not firm, resulting in interruption of current transmission), over-welding (the welding temperature is too high, damaging the battery cell), tin overflow (excess solder flows to the non-welding area of ​​the battery cell), battery cell scratches and even cracks. These problems not only reduce the conversion efficiency of photovoltaic modules and increase the subsequent maintenance costs, but may also cause safety hazards and seriously affect the market competitiveness of the products. For this reason, we propose an automatic welding and processing equipment for photovoltaic modules. Summary of the invention

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 13 The present invention provides a technical solution: an integrated automatic welding and processing device for photovoltaic modules, comprising a placement plate 1, a support leg is arranged at the bottom of the placement plate 1, and two slide rail assemblies 2 are movably arranged on both sides of the placement plate 1, a moving frame 3 is slidably arranged between the two slide rail assemblies 2, and a clamping unit 4 for fixing an electric soldering iron is slidably arranged on the moving frame 3, and a placement groove 5 is opened on the surface of the placement plate 1. During welding, a worker puts a battery cell to be welded into the placement groove 5, and the upper and lower sides of the battery cell abut against the upper and lower sides of the placement groove 5, thereby limiting the battery cell vertically. In order to facilitate the placement of the battery cell into the placement groove 5, the opening side of the placement groove 5 is set to be a trumpet shape:

[0041] A limit block 6 is movably provided on one side of the bottom of the placement plate 1, and a spring is provided on one side of the limit block 6. The limit block 6 is supported by the spring so that the top of the limit block 6 can extend out of the placement plate 1 to limit the battery cell in a normal state. When the battery cell is installed in the placement groove 5, the limit block 6 limits the lateral movement of the battery cell to ensure the stability of the battery cell during welding.

[0042] A guide cleaning unit 7 is movably provided on the placement plate 1 , and the guide cleaning unit 7 can move back and forth on the placement plate 1 , thereby guiding and positioning the welding strip to be welded and cleaning welding slag on both sides of the grid line of the battery cell after welding.

[0043] The slide rail assembly 2 includes a track 21 arranged above the placement plate 1, a fixed block 22 is fixedly arranged on the back side of the track 21, a fixed sleeve 23 is fixedly arranged on the placement plate 1, the fixed block 22 is slidably arranged in the fixed sleeve 23, a support spring 24 is arranged at the bottom of the fixed block 22, and the end of the support spring 24 is fixedly connected to the placement plate 1, and the two ends of the moving frame 3 are respectively slidably arranged in the tracks 21 on both sides, and the track 21 can move up and down above the placement plate 1.

[0044] Contact rollers 8 are rotatably provided at both ends of the movable frame 3, and the outer side of the contact roller 8 abuts against the inner side of the track 21. The contact roller 8 is rotatably provided at the end of the movable frame 3 through a one-way bearing. When the movable frame 3 moves to drive the electric soldering iron for welding, the contact roller 8 cannot rotate at this time, and then sliding friction is generated with the inner wall of the track 21. The moving speed of the movable frame 3 is limited by the friction force, thereby assisting the staff to weld at a uniform speed during welding and ensuring the welding quality. On the contrary, when the movable frame 3 drives the electric soldering iron to reset, the contact roller 8 can rotate at this time, and the movable frame 3 can be quickly reset.

[0045] A sliding sleeve 9 is slidably provided on the outer side of the moving frame 3, and a mounting frame 10 is provided on the sliding sleeve 9. The clamping unit 4 includes a fixed cylinder 41 fixedly provided on the mounting frame 10, and clamping plates 42 are slidably provided on both sides of the fixed cylinder 41. A clamping screw 43 is rotatably provided in the fixed cylinder 41, and the clamping screw 43 is threadedly penetrated through the two clamping plates 42, and the thread directions on both sides of the clamping screw 43 are opposite, and one end of the clamping screw 43 is rotatably penetrated through the fixed cylinder 41 and a handle is provided at the end;

[0046] The electric soldering iron can be fixed by turning the handle to drive the two clamping plates 42 to move closer to each other. The top plane of the mounting frame 10 is set at 45 degrees to ensure that the end of the electric soldering iron can stably contact the soldering strip.

[0047] The top of the sliding sleeve 9 is provided with a mounting groove 11, the bottom of the mounting frame 10 is movably mounted in the mounting groove 11, and the mounting groove 11 and the bottom of the mounting frame 10 are respectively provided with mounting magnetic blocks 12 that attract each other, and a pressing rod 13 is slidably arranged in the sliding sleeve 9, the pressing rod 13 slides through the sliding sleeve 9 and the bottom end of the pressing rod 13 abuts against the moving frame 3;

[0048] During welding, the staff needs to actively apply force by pressing down with the handheld soldering iron to drive the mounting frame 10 to squeeze the pressing rod 13. At this time, the bottom end of the pressing rod 13 abuts against the movable frame 3, thereby limiting the movement of the sliding sleeve 9 on the movable frame 3. At the same time, the movable frame 3 will also drive the track 21 to move downward, thereby making the soldering iron contact the soldering strip, and then the staff drives the soldering iron to move for welding.

[0049] Slide grooves 14 are provided on both sides of the placement plate 1. The slide grooves 14 are located on one side of the limit block 6. A driving rod 15 is slidably provided in the slide grooves 14. The bottom end of the driving rod 15 extends to the bottom of the placement plate 1 and is connected to a rack 16. Gears 17 meshing with the rack 16 are rotatably provided on both sides of the bottom of the placement plate 1. A rotating rod 18 is coaxially provided at the bottom of the gear 17. The upper surface of the rotating rod 18 and the bottom of the limit block 6 are respectively embedded with mutually attractive limit magnetic blocks 19;

[0050] Before welding is completed, the limit block 6 extends out of the placement plate 1 to play a limiting role. When the staff drives the movable frame 3 to move, at the end of welding, as the movable frame 3 gradually moves, the movable frame 3 abuts against the driving rod 15 to move it, and the driving rod 15 drives the rack 16 to move. When the rack 16 moves, it engages with the gear 17 to drive it to rotate, and then drives the rotating rod 18 to rotate to the bottom of the limit block 6. At this time, the two limit magnets 19 attract each other, causing the limit block 6 to shrink into the placement plate 1. At this time, welding has been completed, and the staff can push the battery cell out along the placement slot 5.

[0051] A rotary groove 20 is provided on both sides of the placement plate 1, and the guide cleaning unit 7 includes a driving block 71 and a transmission block 72, which are respectively slidably arranged on the upper and lower sides of the rotary groove 20, and a connecting belt 73 is arranged between the driving block 71 and the transmission block 72, and the connecting belt 73 has the same profile as the rotary groove 20, so that the driving block 71 can drive the transmission block 72 to move in the opposite direction in the rotary groove 20 when moving;

[0052] A connecting frame 74 is fixedly provided on the driving block 71, a side rod 75 is fixedly provided on the transmission block 72, a connecting spring 76 is provided on one side of the side rod 75, a transmission rod 77 is provided at the end of the connecting spring 76, a movable groove 78 is also provided on the placement plate 1, a movable block 79 is slidably provided in the movable groove 78, the movable block 79 is connected to one end of the transmission rod 77, and a guide frame 710 is fixedly provided at the other end of the transmission rod 77, a notch for guiding the welding strip is provided in the guide frame 710, and a high-temperature cloth 711 for wiping welding slag is also provided at the bottom of the guide frame 710;

[0053] When the driving block 71 moves, it can drive the transmission block 72 to move in the opposite direction. When the transmission block 72 moves along the welding direction, the transmission block 72 drives the side rod 75 to move. The side rod 75 abuts against the transmission rod 77 to move it. When the transmission rod 77 moves, it drives the guide frame 710 to move. At this time, the guide frame 710 can sort out and align the welding ribbon held by the staff.

[0054] A positioning groove 25 is further provided on the placement plate 1 at one side of the movable groove 78, a positioning rod 26 is slidably provided in the positioning groove 25, a top rod 27 is fixedly provided at one end of the positioning rod 26, a return spring 28 is provided in the positioning groove 25, and both ends of the return spring 28 are respectively connected to the positioning rod 26 and the side wall of the positioning groove 25, and mutually attracted positioning magnetic blocks 29 are embedded in the end of the positioning rod 26 and the movable block 79, and the attraction between the positioning magnetic blocks 29 is greater than the elastic force of the connecting spring 76;

[0055] When the transmission rod 77 drives the movable block 79 to move to the end of the movable groove 78, the movable groove 78 and the positioning magnet 29 inside the positioning rod 26 attract each other to position the movable block 79, and then position the transmission rod 77. Then, when the transmission block 72 is reset, the transmission block 72 drives the side rod 75 to move. Since the attraction between the positioning magnets 29 is greater than the elastic force of the connecting spring 76, the transmission rod 77 does not move when the side rod 75 moves, thereby stretching the connecting spring 76. Only when the moving frame 3 moves and drives the top rod 27 to drive the positioning rod 26 to move, the positioning magnet 29 in the positioning block is away from the positioning magnet 29 in the movable block 79. At this time, the restriction on the transmission rod 77 can be cancelled. At this time, under the reset force of the connecting spring 76, the transmission rod 77 moves and drives the guide frame 710 and the high-temperature cloth 711 to move. When the high-temperature cloth 711 moves, it can clean both sides of the welding strip.

[0056] Elastic telescopic rods 30 are fixedly provided on both sides of the sliding sleeve 9, and holes for inserting the elastic telescopic rods 30 are opened on the connecting frame 74. Generally, only two welding strips need to be welded on a small battery cell. During welding, the movable frame 3 can be moved according to the upper and lower positions required for welding, thereby driving the sliding sleeve 9 to move, so that the elastic telescopic rods 30 are plugged into the connecting frame 74, so that when the movable frame 3 moves, it can drive the connecting frame 74 and the driving block 71 to move.

[0057] In summary, the workflow is as follows:

[0058] Preparation stage: Place the photovoltaic module automatic welding processing equipment on a stable workbench and ensure that the supporting legs are stable; check whether the slide rail assembly 2, mobile frame 3, clamping unit 4, guide cleaning unit 7 and other components are installed correctly and function properly; place the battery cell to be welded into the placement groove 5 of the placement plate 1, and ensure that the upper and lower sides of the battery cell are in close contact with the upper and lower sides of the placement groove 5 for vertical limiting; adjust the position of the mobile frame 3 according to the position of the welding strip to be welded, and connect it with the connecting frame 74 through the elastic telescopic rod 30 to ensure that the driving block 71 of the guide cleaning unit 7 can be driven to move when the mobile frame 3 moves.

[0059] Battery cell limiting: The limiting block 6 at the bottom of the placement plate 1 extends out under the action of the spring to limit the battery cell laterally to ensure that the battery cell remains stable during the welding process.

[0060] Welding process: the staff holds the electric soldering iron and fixes it on the mounting frame 10 of the sliding sleeve 9 on the mobile frame 3 through the clamping unit 4; the initial position of the mobile frame 3 is at the far right, and it needs to be moved to the far left before welding. During the movement of the mobile frame 3, the driving block 71 drives the transmission block 72 to move in the opposite direction, and the transmission block 72 drives the transmission rod 77 to move through the side rod 75, thereby driving the guide frame 710 to move, and the guide frame 710 combs and aligns the welding strip to ensure that the welding strip is aligned with the battery cell grid line. When the mobile frame 3 moves to the far left, the electric soldering iron is pressed downward to make the mounting frame 10 squeeze the pressing rod 13, thereby limiting the movement of the sliding sleeve 9 on the mobile frame 3. At the same time, the mobile frame 3 drives the track 21 to move downward so that the electric soldering iron contacts the welding strip; the mobile frame 3 is pushed to move to the right to make it move along the slide rail assembly 2. At this time, the contact roller 8 and the inner wall of the track 21 produce sliding friction, which limits the moving speed of the mobile frame 3 and ensures that the welding process is carried out at a uniform speed.

[0061] Welding slag cleaning: During the welding process, the movable frame 3 drives the driving block 71 to move, the driving block 71 drives the transmission block 72 to move, and the transmission block 72 drives the side rod 75 to move, but because the attraction between the positioning magnetic blocks 29 is greater than the elastic force of the connecting spring 76, the transmission rod 77 remains stationary and the connecting spring 76 is stretched; when the welding of the movable frame 3 is completed, the movable frame 3 abuts against the top rod 27 to drive the positioning rod 26 to move, and the positioning magnetic block 29 in the positioning block is away from the positioning magnetic block 29 in the movable block 79, thereby canceling the restriction on the transmission rod 77; under the reset force of the connecting spring 76, the transmission rod 77 moves, driving the guide frame 710 and the high-temperature cloth 711 to move, and the high-temperature cloth 711 wipes both sides of the welding strip to clean the welding slag.

[0062] Repeat welding: If another welding strip needs to be welded, repeat the above steps, adjust the position of the sliding sleeve 9, move the movable frame 3 again according to the position of the welding strip to be welded, and perform welding and welding slag cleaning.

[0063] Battery cell removal: After all welding is completed, the staff can push the welded battery cell out along the placement groove 5 and proceed to the welding operation of the next battery cell.

[0064] Example 2: Please refer to Fig.14 On the basis of Example 2, a magnetic pressure wheel 31 is movably provided in the guide frame 710. When the guide frame 710 moves above the battery cell, the magnetic pressure wheel 31 rolls. A magnetic plate that is attracted to the magnetic pressure wheel 31 is embedded on the surface of the placement plate 1. The magnetic pressure wheel 31 is attracted by the magnetic plate and then the magnetic pressure wheel 31 is pressed downward against the welding strip. Therefore, when the guide frame 710 moves, the guide frame 710 can not only straighten the welding strip, but also flatten the welding strip through the magnetic pressure wheel 31 and adjust and lock the position of the welding strip by cooperating with the notch at the end of the guide frame 710.

[0065] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0066] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
