Description

Technical Field

[0001] The present invention relates to the technical field of welding processing equipment, in particular to a positioning welding tool for processing a solar photovoltaic bracket. Background Art

[0002] Solar photovoltaic brackets are metal structural supports used to place, install, and secure solar panels in solar photovoltaic power generation systems. As the "skeleton" of a photovoltaic power station, they support the power generation and are a key component of photovoltaic power generation systems. Depending on the environment and installation requirements, photovoltaic brackets can be divided into fixed, tilt-adjustable, automatic tracking, and flexible brackets. Fixed brackets allow the photovoltaic array to receive solar radiation in a fixed manner. Depending on local geographical and climatic conditions, the bracket is maintained at an angle conducive to receiving solar radiation. Once the position is fixed, it is generally not frequently adjusted. Tilt-adjustable brackets can be manually adjusted to increase direct sunlight absorption and improve power generation. Automatic tracking brackets can automatically adjust their angle as the angle of incidence changes, effectively increasing power generation. Flexible brackets are suitable for a variety of large-span application sites and can improve land utilization.

[0003] As an important supporting structure of the photovoltaic power generation system, the installation of solar photovoltaic brackets needs to closely adapt to the size of the solar panels. However, the specifications of solar panels often change due to factors such as the installation environment and power generation needs. Therefore, in actual applications, photovoltaic brackets often need to be customized for welding and installation according to on-site working conditions. At present, hot-dip galvanized steel has become the mainstream material for photovoltaic brackets due to its advantages such as low cost, high strength and strong corrosion resistance. However, during the welding process, the galvanized layer on the surface of the steel will produce zinc vapor due to high temperature melting. These vapors are blocked from escaping when the weld cools and solidifies, and it is very easy to form defects such as pores and cracks at the weld, affecting the structural strength and service life of the bracket. Therefore, those skilled in the art have proposed a positioning welding tool for processing solar photovoltaic brackets to solve the above-mentioned technical problems. Summary of the Invention

[0020] Working principle: When welding the solar photovoltaic bracket, the positioning moving mechanism is started first, and the staff first opens the opening door on the closed cover. Then the staff picks up the two sections of photovoltaic brackets that need to be welded and inserts them between the two separate connecting seats. In the process of inserting the photovoltaic bracket, the welding ends of the two sections of the photovoltaic bracket are separated by the partition plate on the mounting seat 1, and then the outer ends of the photovoltaic bracket are placed into the positioning seat for positioning. At the same time, the partition plate on the mounting seat 1 is used to ensure its stability in the subsequent positioning process. Then the micro-air pump on the rotating seat is started. At the same time, the micro-air pump injects gas into the airbag seat through the connecting pipe at the same time. As the gas in the airbag seat continues to increase, the airbag seat expands and drives the separation connecting seat inside it to move closer to the center position simultaneously. When the separation connecting seat moves, it also drives the sponge seat on it to fit the position of the photovoltaic bracket, and when the sponge seat is fitted, it is squeezed to produce shape. The change increases the friction between its surface and the outer surface of the photovoltaic bracket, thereby positioning the photovoltaics before subsequent processing, and then the linear moving module in the moving groove is started, and the linear moving module drives the fixed seat on it and the positioned photovoltaic bracket to move synchronously when starting. The photovoltaic bracket drives the positioning seats on both ends of its outside and the moving seat to move synchronously in the inclined wall groove of the bar seat when moving. Affected by the inclination of the inner wall of the inclined wall groove, the photovoltaic bracket moves as it is driven and moves after it separates from the partition plate. The middle distance between the two sections of the photovoltaic bracket will decrease as the moving distance changes. At the same time, during the movement of the photovoltaic bracket, the driving motor in the moving seat is started, and the rotating shaft of the driving motor drives the moving seat and the positioning seat on it to rotate synchronously while rotating. The positioning seat drives the photovoltaic bracket inside it to rotate synchronously while rotating, thereby facilitating the subsequent processing of the photovoltaic bracket, thereby completing the positioning and moving processing of the photovoltaic bracket;Then the preheating and slow cooling mechanism is started. When the photovoltaic bracket to be processed is moved to the bottom of the arc seat through the positioning and moving mechanism, the high-pressure air pump on the closed cover is started. The high-pressure air pump injects gas into the inside of the diversion cover through the connecting pipe. The gas entering the diversion cover is diverted and evenly dispersed into the inside of the arc seat. Then the heating wire on the mounting rod is powered on to heat the gas entering the arc seat. The heated airflow is then sprayed out of the port position of the photovoltaic bracket through the slot at the bottom of the arc seat, and the positioning and moving mechanism is used to rotate the photovoltaic bracket to complete the preheating treatment of the photovoltaic bracket at the front end of the welding. Then, welding and surface treatment are performed on the two ports of the photovoltaic bracket. After that, when the photovoltaic bracket is driven by the positioning moving mechanism to move to the bottom position of the arc seat during the return process, the high-pressure air pump on the closed cover is started again, and the staff reduces the operating power of the high-pressure air pump. Then the high-pressure air pump injects gas into the inside of the diverter cover through the connecting pipe, and the gas entering the diverter cover is evenly dispersed into the inside of the arc seat after diversion. Then the airflow entering the arc seat is sprayed out of the welding position of the photovoltaic bracket through the slot at the bottom of the arc seat, and cooperates with the positioning moving mechanism to rotate the photovoltaic bracket, thereby completing the slow cooling treatment of the photovoltaic bracket after welding and surface treatment; then the weld treatment mechanism is started, and the welding process is carried out by the preheating and slow cooling mechanism. After the ends of the photovoltaic bracket are uniformly preheated before processing, the positioning moving mechanism drives the photovoltaic bracket to move again, so that the photovoltaic bracket after movement reaches the position of the mounting seat three, so that the two ends of the photovoltaic bracket are in contact with the sponge grinding disc on the mounting frame, and due to the material properties of the sponge grinding disc, the surfaces of the sponge grinding disc will produce corresponding deformations when the two ends of the photovoltaic bracket are in contact with the sponge grinding disc. After deformation, the sponge grinding disc can not only contact with the two ends of the photovoltaic bracket, but also contact with the outer wall positions at both ends of the photovoltaic bracket. Then, the positioning moving mechanism synchronously drives the photovoltaic bracket to rotate, and the photovoltaic bracket rotates while contacting the mounting frame The upper sponge grinding disc cooperates to grind the galvanized layers at both ends of the photovoltaic bracket, and then the photovoltaic bracket after grinding is guided by the positioning and moving mechanism to reach the bottom position of the second mounting seat. At this time, affected by the inclined wall groove in the strip seat, the photovoltaic brackets at both ends that reach the bottom of the second mounting seat are squeezed by the inclined wall groove, so that the end positions of the two sections of the photovoltaic bracket after grinding are fitted together, and then the welding gun at the bottom of the second mounting seat is started to weld the contact and fitting positions of the two sections of the photovoltaic bracket. At the same time, through the auxiliary rotation of the positioning and moving mechanism, the two end positions of the photovoltaic bracket are evenly welded, thereby completing the grinding and welding of the galvanized layer at the weld position of the photovoltaic bracket;After that, the surface treatment mechanism is started, and the photovoltaic bracket treated by the weld treatment mechanism is guided to the bottom position of the crossbar seat by the positioning movement mechanism, and then the material melter is started, and the material melter heats and melts the zinc material. Then the staff opens the electromagnetic control valve at the bottom of the material melter through the control device, so that the melted zinc material in the material melter enters the temporary storage box on the crossbar seat through the connecting pipe. At the same time, the high-pressure air pump also injects high-pressure gas into the temporary storage box through the connecting pipe, and then the melted zinc material is atomized into fine particles through the atomizing nozzle at the bottom of the crossbar seat, and is driven by the high-speed airflow to be sprayed on the photovoltaic bracket. The surface of the welding position of the frame is fixed, thus completing the surface treatment of the photovoltaic bracket after welding. Finally, the photovoltaic bracket after welding is guided and moved by the positioning and moving mechanism, so that the photovoltaic bracket after surface treatment is restored to the bottom position of the arc seat. Then, the galvanized material after its surface treatment is slowly cooled and shaped. After that, the photovoltaic bracket after slow cooling and shaping is pulled and guided by the positioning and moving mechanism to return to its original position. Then, the gas in the airbag seat is discharged, and the staff opens the opening door on the closed cover to take out the photovoltaic bracket after welding, thus completing the processing of the solar photovoltaic bracket.

[0021] The present invention provides a positioning welding tool for processing solar photovoltaic brackets.

[0022] Beneficial effects:

[0023] 1. The present invention adds and sets a positioning and moving mechanism. Before the solar photovoltaic bracket is welded, the mechanism positions the photovoltaic bracket before processing and guides the movement during the processing. On the one hand, it can ensure the accuracy and stability of the subsequent photovoltaic bracket during welding, thereby improving the overall quality of the photovoltaic bracket product after processing, effectively avoiding the random deviation of traditional manual positioning, and significantly improving the position accuracy and stability during welding. On the other hand, it can also promote the process of photovoltaic bracket processing, improve its processing efficiency of photovoltaic brackets, and avoid the problems of material damage and high labor intensity caused by traditional manual brick moving.

[0024] 2. The present invention adds and sets a preheating and slow cooling mechanism. Before the solar photovoltaic bracket is welded, the mechanism uniformly preheats the welding end of the bracket, so that the bonding force between the galvanized layer and the substrate is weakened under the action of heat, which facilitates the efficient removal of the galvanized layer on the surface of the bracket, and also avoids damage to the substrate or residual zinc layer caused by forced peeling. At the same time, the preheating process can initially release the internal stress of the material, reduce the risk of deformation caused by sudden heating during welding, and ensure the geometric stability of the bracket structure during the processing process. After welding and surface treatment are completed, the preheating and slow cooling mechanism switches to the slow cooling mode, and the welding area and the zinc spraying layer are cooled at an appropriate rate through controllable airflow circulation. This slow cooling method can effectively inhibit the brittle and hard structure of the weld metal due to rapid cooling, reduce welding stress concentration, and avoid cracking or peeling of the zinc spraying layer due to excessive temperature difference, thereby improving the bonding strength between the coating and the substrate. Through the synergy of preheating and slow cooling processes, the mechanism not only optimizes the galvanizing layer processing efficiency and welding quality, but also reduces potential hidden dangers such as material deformation and coating failure from the source of the process.

[0025] 3. The present invention adds and sets a weld joint processing mechanism. Before welding the solar photovoltaic bracket, the mechanism adopts an integrated preheating and grinding processing method. First, the galvanized layer at the welding position is moderately preheated by a heating device to reduce the bonding strength between the zinc layer and the substrate, and then the coating is accurately removed by grinding. This process can not only avoid substrate scratches or zinc layer residues caused by traditional cold grinding, but also reduce grinding resistance through temperature control, thereby improving the coating removal efficiency. Compared with traditional manual processing, the mechanism realizes standardization and continuity of weld joint processing through automated operations. On the one hand, the thoroughly removed galvanized layer can prevent defects such as pores and cracks caused by the escape of zinc vapor during welding, thereby improving the density and mechanical properties of the weld from the source and ensuring the stability of the bracket structure. On the other hand, the fully automated operation does not require direct manual contact with high-temperature components or harmful dust, reducing the risk of burns and inhalation injuries to operators. At the same time, it eliminates the need for manual loading and unloading and tool changing, thereby significantly improving the efficiency of weld joint processing.

[0026] 4. The present invention adds and sets a surface treatment mechanism. After the welding of the solar photovoltaic bracket is completed, the mechanism uses high-speed airflow to accurately spray molten zinc material onto the welding surface, fills the weld depressions and repairs the galvanized layer damaged by welding through a thermal spraying process, so that the surface can be restored to a uniform and continuous anti-corrosion barrier. During the spraying process, the molten zinc particles form a mechanical bite and local metallurgical bond with the substrate to enhance the adhesion of the coating. After the repair is completed, the mechanism performs controllable cooling on the welding point and the repair area by slow cooling to avoid coating cracking or substrate stress concentration caused by rapid cooling. The synergistic effect of multiple treatment methods can not only efficiently restore the anti-corrosion performance of the bracket surface, but also improve the repair consistency through automated operation, avoiding the problems of missed coating or uneven thickness caused by manual brushing. The whole process not only ensures the long-term weather resistance of the photovoltaic bracket, but also improves the repair efficiency through mechanized operation.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings 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 making creative efforts are within the scope of protection of the present invention.

[0039] Please see the attached Figure 1 -Attached Figure 2 The embodiment of the present invention provides a positioning welding tool for processing solar photovoltaic brackets, comprising a base 1, on which a closed cover 3 is arranged, and the closed cover 3 and the interior of the base 1 form a closed processing space; an opening door 2, which is arranged in the middle of one side of the closed cover 3, is used by workers to put the photovoltaic bracket in before processing and take it out after processing; an observation window 6, which is arranged in the middle of the front side of the closed cover 3,

[0040] Please see the attached Figure 3 -Attached Figure 5 , a positioning and moving mechanism, which is arranged on the top of the base 1, and is used for fixing and positioning the photovoltaic bracket before processing and moving it during processing;

[0041] The positioning movement mechanism includes a moving groove 20. Moving grooves 20 are opened on both sides of the middle part of the top of the base 1. A linear moving module 7 is arranged inside the moving groove 20. The top of the linear moving module 7 is fixedly connected to the fixed seat 21. The top of the fixed seat 21 is fixedly connected to the mounting ring seat 10. The inner side of the mounting ring seat 10 is rotatably connected to the rotating seat 9. An airbag seat 22 is arranged on the inner wall of the rotating seat 9. A micro air pump 23 is arranged on one side of the outer wall of the rotating seat 9, and the exhaust end of the micro air pump 23 is connected to the interior of the corresponding airbag seat 22 through a connecting pipe. A plurality of separation and connection seats 24 are arranged in a circular array on the middle circumference of the inner wall of the airbag seat 22, and a sponge seat 25 is arranged on the inner middle part of the separation and connection seat 24.

[0042] When the positioning and moving mechanism is started, the staff first opens the opening door 2 on the closing cover 3, and then the staff picks up the two sections of photovoltaic brackets that need to be welded and inserts them between the two separation and connection seats 24. During the insertion of the photovoltaic bracket, the welding ends of the two sections of the photovoltaic bracket are separated by the partition plate 12 on the mounting seat 13, and then the outer ends of the photovoltaic bracket are placed into the positioning seat 11 for positioning. At the same time, the partition plate 12 on the mounting seat 13 is used to ensure its stability in the subsequent positioning process.

[0043] The positioning and moving mechanism also includes a connecting rod 8, and the two fixed seats 21 are connected by the connecting rod 8 at the middle and lower parts of the side close to the open door 2. A mounting seat 13 is fixedly connected to one side of the middle part of the top of the inner wall of the closed cover 3, and the inner middle part of the mounting seat 13 is rotatably connected to the partition plate 12. The middle and upper parts of the inner sides of the closed cover 3 are fixedly connected to the strip seats 14, and the middle part of the adjacent side of the strip seats 14 is provided with an inclined wall groove 27. The inside of the inclined wall groove 27 is slidably connected with a moving seat 26, and the middle part of the adjacent side of the moving seat 26 is rotatably connected with the positioning seat 11, and the positioning seat 11 is open on the side close to the open door 2. A driving motor 28 is provided in the inner middle part of the moving seat 26, and the output end of the driving motor 28 is connected to the middle part of the positioning seat 11.

[0044] Then the micro air pump 23 on the rotating seat 9 is started, and the micro air pump 23 simultaneously injects gas into the airbag seat 22 through the connecting tube while starting. As the gas in the airbag seat 22 continues to increase, the airbag seat 22 expands while driving the separation and connection seat 24 inside it to move closer to the center position. While moving, the separation and connection seat 24 also simultaneously drives the sponge seat 25 on it to fit the position of the photovoltaic bracket, and when the sponge seat 25 fits, it is squeezed and deformed, which increases the friction between its surface and the outer surface of the photovoltaic bracket, thereby positioning the photovoltaics before subsequent processing.

[0045] After that, the linear moving module 7 in the moving groove 20 is started. When the linear moving module 7 is started, it drives the fixed seat 21 on it and the photovoltaic bracket after positioning to move synchronously. When the photovoltaic bracket moves, it drives the positioning seats 11 on its two outer ends and the moving seat 26 to move synchronously in the inclined wall groove 27 of the bar seat 14. Affected by the inclination of the inner wall of the inclined wall groove 27, the photovoltaic bracket moves as it is driven to move. After it separates from the partition plate 12, the middle distance between the two sections of the photovoltaic bracket will decrease as the moving distance changes. At the same time, during the movement of the photovoltaic bracket, the driving motor 28 in the moving seat 26 is started. The rotating shaft of the driving motor 28 drives the moving seat 26 and the positioning seat 11 on it to rotate synchronously while rotating. The positioning seat 11 drives the photovoltaic bracket inside it to rotate synchronously while rotating, thereby facilitating the subsequent processing of the photovoltaic bracket, thereby completing the positioning and moving processing of the photovoltaic bracket.

[0046] When the connecting rod 8 on the fixing seat 21 moves before welding, when passing the mounting bracket 34, the connecting rod 8 presses it, thereby causing the mounting bracket 34 on the mounting seat 31 to rotate and tilt, thereby facilitating the movement of the photovoltaic bracket. When the mounting bracket 34 rotates and tilts, it drives the torsion spring 36 on the rotating rod 33 to rotate and tighten it. Then, when the surface treatment of the photovoltaic bracket is completed, it is reset to the bottom of the arc seat 29 for slow cooling treatment. The limit imposed on the mounting bracket 34 disappears, and the torsion spring 36 on the rotating rod 33 drives the mounting bracket 34 to rotate and reset to a vertical state in the mounting seat 3 19. Then, during the resetting movement of the connecting rod 8, the connecting rod 8 squeezes the mounting bracket 34 in the mounting seat 3 19 again, so that the photovoltaic bracket after surface treatment can smoothly reach the slow cooling treatment position. Finally, when the connecting rod 8 moves to the position where the limit on the mounting bracket 34 disappears, similarly, the torsion spring 36 on the rotating rod 33 drives the mounting bracket 34 to reset to a vertical state.

[0047] Similarly, the partition plate 12 at the bottom of the mounting seat 13 can be pushed to rotate on the mounting seat 13 during the process of moving and resetting the photovoltaic bracket after welding and surface treatment, thereby preventing the partition plate 12 from obstructing the photovoltaic bracket after welding.

[0048] Please see the attached Figure 6 -Attached Figure 7 , a preheating and slow cooling mechanism is provided on one side of the middle portion of the top of the inner wall of the closed cover 3, and is used to preheat the two ends of the photovoltaic bracket before the weld treatment and to perform a uniform and slow cooling treatment at the position of the weld after the surface treatment;

[0049] The preheating and slow cooling mechanism includes an arc-shaped seat 29. An arc-shaped seat 29 is provided on one side of the middle of the top inner wall of the closed cover 3. A plurality of slots 30 are equidistantly provided on the inner wall of the arc-shaped seat 29. A plurality of mounting rods 31 are equidistantly fixedly connected to the interior of the arc-shaped seat 29. A heating wire 32 is provided on each mounting rod 31. A diverter cover 15 is provided in the middle of the top of the arc-shaped seat 29. The diverter cover 15 is used to evenly divert the airflow entering the interior thereof to various positions and discharge it into the arc-shaped seat 29 at the bottom. A high-pressure air pump 4 is provided on one side of the middle of the top inner wall of the closed cover 3. The exhaust end of the high-pressure air pump 4 is connected to the interior of the diverter cover 15 through a connecting pipe.

[0050] When the preheating and slow cooling mechanism is started, when the photovoltaic bracket to be processed is moved to the bottom of the arc seat 29 through the positioning and moving mechanism, the high-pressure air pump 4 on the closing cover 3 is started, and the high-pressure air pump 4 injects gas into the inside of the diverter cover 15 through the connecting pipe. The gas entering the diverter cover 15 is diverted and evenly dispersed into the interior of the arc seat 29. Then the heating wire 32 on the mounting rod 31 is powered on and started, thereby heating the gas entering the arc seat 29. The heated airflow is then sprayed out of the port position of the photovoltaic bracket through the slot 30 at the bottom of the arc seat 29, and the positioning and moving mechanism is used to rotate the photovoltaic bracket, thereby completing the preheating treatment of the photovoltaic bracket at the front end of the welding.

[0051] Then, after the two ports of the photovoltaic bracket are welded and surface treated, the photovoltaic bracket is driven by the positioning and moving mechanism to move to the bottom position of the arc seat 29 during the return process. At this time, the high-pressure air pump 4 on the closed cover 3 is restarted. At the same time, the staff reduces the operating power of the high-pressure air pump 4, and then the high-pressure air pump 4 injects gas into the inside of the diverter cover 15 through the connecting pipe. The gas entering the diverter cover 15 is diverted and evenly dispersed into the inside of the arc seat 29. Then, the airflow entering the arc seat 29 is sprayed out at the welding position of the photovoltaic bracket through the slot 30 at the bottom of the arc seat 29, and cooperates with the positioning and moving mechanism to rotate the photovoltaic bracket, thereby completing the slow cooling treatment of the photovoltaic bracket after welding and surface treatment.

[0052] Please see the attached Figure 8 -Attached Figure 9 , a weld joint processing mechanism, which is arranged on one side of the middle part of the top of the base 1, and is used to remove the galvanized layer and perform welding processing on the weld joint positions of the two adjacent ends of the photovoltaic bracket after the preheating treatment of the preheating and slow cooling mechanism is completed;

[0053] The weld processing mechanism includes a mounting seat three 19, and the mounting seat three 19 is fixedly connected to one side of the middle part of the top of the base 1. The middle part of the mounting seat three 19 is rotatably connected to a rotating rod 33, and the middle part of the rotating rod 33 is rotatably connected to a mounting frame 34. Torsion springs 36 are provided at both ends of the middle part of the rotating rod 33, and a sponge grinding disc 35 is provided in the middle part of the mounting frame 34.

[0054] When the weld processing mechanism is started, after the preheating and slow cooling mechanism uniformly preheats the ends of the photovoltaic bracket before the welding processing, the positioning and moving mechanism drives the photovoltaic bracket to move again, so that the photovoltaic bracket after movement reaches the position of the mounting seat 3 19, so that the two ends of the photovoltaic bracket contact with the sponge grinding disk 35 on the mounting frame 34, and due to the material properties of the sponge grinding disk 35, the surface of the sponge grinding disk 35 will produce corresponding deformation when the two ends of the photovoltaic bracket contact with the sponge grinding disk 35, and the sponge grinding disk 35 after deformation can not only contact with the two ends of the photovoltaic bracket, but also contact with the outer wall positions at both ends of the photovoltaic bracket, and then the positioning and moving mechanism synchronously drives the photovoltaic bracket to rotate, and while the photovoltaic bracket rotates, it cooperates with the sponge grinding disk 35 on the mounting frame 34 to grind the galvanized layer at both ends of the photovoltaic bracket.

[0055] The weld processing mechanism also includes a second mounting seat 16 , which is provided at the middle of the top of the inner wall of the closing cover 3 away from the opening door 2 , and a welding gun 17 is provided at the middle of the bottom end of the second mounting seat 16 .

[0056] Then the photovoltaic bracket after grinding is guided by the positioning and moving mechanism to reach the bottom position of the mounting seat 2 16. At this time, affected by the inclined wall groove 27 in the strip seat 14, the photovoltaic brackets at both ends that reach the bottom of the mounting seat 2 16 are squeezed by the inclined wall groove 27, so that the end positions of the two sections of the photovoltaic bracket after grinding are fitted together. Then the welding gun 17 at the bottom of the mounting seat 2 16 is started to weld the contact and fitting positions of the two sections of the photovoltaic bracket. At the same time, through the auxiliary rotation of the positioning and moving mechanism, the two end positions of the photovoltaic bracket are evenly welded, thereby completing the grinding and welding of the galvanized layer at the weld position of the photovoltaic bracket.

[0057] Please see the attached Figure 10 , a surface treatment mechanism is arranged on one side of the middle part of the top of the inner wall of the closed cover 3, and is used to restore the surface of the photovoltaic bracket connection after the welding process is completed.

[0058] The surface treatment mechanism includes a crossbar seat 18, and the crossbar seat 18 is fixedly connected to the middle and upper part of the side of the closing cover 3 away from the opening door 2. A temporary storage box 37 is provided in the middle of the top of the crossbar seat 18, and a material melter 5 is provided on one side of the middle of the top of the closing cover 3. The discharge port of the material melter 5 is connected to the interior of the temporary storage box 37 through a connecting pipe, and an electromagnetic control valve is provided on the connecting pipe for controlling the flow of the material after melting.

[0059] The top of one side of the temporary storage box 37 is connected to the gas outlet of the high-pressure air pump 4 through a connecting pipe. An atomizing spray row 38 is provided in the middle of the bottom end of the crossbar seat 18, and the feed port of the atomizing spray row 38 is connected to the bottom of the temporary storage box 37.

[0060] When the surface treatment mechanism is started, the photovoltaic bracket after being processed by the weld treatment mechanism is guided and moved to the bottom position of the cross bar seat 18 by the positioning and moving mechanism, and then the material melter 5 is started, and the material melter 5 heats and melts the zinc material. Then the staff opens the electromagnetic control valve at the bottom through the control equipment, so that the melted zinc material in the material melter 5 enters the temporary storage box 37 above the cross bar seat 18 through the connecting pipe. At the same time, the high-pressure air pump 4 also synchronously injects high-pressure gas into the temporary storage box 37 through the connecting pipe, and then the melted zinc material is atomized into fine particles through the atomizing nozzle 38 at the bottom of the cross bar seat 18, and is driven by high-speed airflow to be sprayed on the surface of the welding position of the photovoltaic bracket, thereby completing the surface treatment operation of the photovoltaic bracket after welding.
