Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic bracket welding, and in particular to a welding device for assembling a photovoltaic bracket. Background Art

[0002] Solar photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. They are generally made of aluminum alloy, carbon steel and stainless steel. They are stable and durable and can withstand the weight of solar panels as well as the influence of wind and other external factors. The installation and adjustment of photovoltaic brackets require professional techniques and tools to ensure the stability and performance of solar panels. When installing photovoltaic brackets, relevant safety regulations and building standards must be followed to ensure the stability and reliability of the installation.

[0003] In the prior art, in the process of assembling and welding a photovoltaic bracket, it is usually composed of a water tank, a water pump, a radiator, a water pipe and a water cooling channel inside the welding head. The water pump draws out the coolant (usually water or a special coolant) in the water tank and transports it to the water cooling channel of the welding head through the water pipe. After the coolant absorbs the heat of the welding head, it flows back to the radiator and dissipates the heat to the surrounding environment through the radiator. The cooled coolant enters the circulation again to complete the cooling of the welding head. However, if hard water is used as the cooling water source, the calcium, magnesium and other ions contained in the water are very likely to form insoluble scale such as calcium carbonate and magnesium hydroxide in the heated environment of the cooling water pipe. As time accumulates, the scale continues to thicken, causing the inner diameter of the water pipe to gradually shrink, seriously hindering the circulation of the coolant, and then affecting the cooling effect. If it is not discovered and solved in time, it is easy to cause damage to the welding head and reduce its service life. How to invent a welding device for assembling a photovoltaic bracket to solve these problems has become an urgent problem to be solved by technicians in this field. Summary of the invention

[0015] The beneficial effects of the present invention are: 1. During the use of the equipment, the welding head can be cooled down through the pipeline assembly. When the spiral cooling tube is heated for a long time, the internal scale will continue to thicken, causing the inner diameter of the water pipe to gradually shrink. Therefore, the water pressure inside the connection box will gradually increase, and then the extrusion block will squeeze the pressure sensor, so that the water pump 1 is closed, and the chemical solution stored in the liquid storage box is released to the inside of the spiral cooling tube through the one-way drainage pipe through the water pump 2, and the released chemical solution can diffuse into the cooling water. After a certain period of soaking, the water pump 1 is restarted, and the inner wall of the spiral cooling tube is repeatedly flushed by the flow of cooling water to reduce the attachment of impurities to the inner wall of the spiral cooling tube, ensure the cooling effect of the welding head, and avoid the welding head being in a high temperature environment for a long time, so that the material performance of key components such as the internal electrode and the conductive nozzle will decline rapidly. Through timely heat dissipation and cooling, the thermal damage of these components is slowed down and the service life is extended. At the same time, when the water pump 1 is started to flush the spiral cooling tube, the liquid containing impurities will flow back to the inside of the water tank through the telescopic tube 1, and will be reused after being filtered by the filter cartridge to reduce the waste of resources and improve the utilization effect.

[0016] 2. When the cylinder drives the welding head downward, it will also drive the support plate to move synchronously. At this time, the connecting rope wound inside the reel is pulled and released, thereby driving the filter cartridge to rotate inside the water tank through the fixed shaft. At this time, the impurities attached to the surface of the filter cartridge can be cleaned by the scraper to reduce the blockage of the filter cartridge and improve the filtering effect. A soft brush can be set at the contact point between the scraper and the filter cartridge to ensure the cleaning effect. When the filter cartridge rotates, the torsion spring will undergo elastic deformation. When the cylinder drives the welding head to rise, the elastic recovery of the torsion spring allows the reel to rewind the connecting rope and drive the filter cartridge to reverse. The filter cartridge can be cleaned again by the scraper. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0021] Example 1. Refer to Figure 1-Figure 9 , a welding device for assembling a photovoltaic bracket, including a support frame 1 and a processing table 2. The support frame 1 is connected to a support base 3. An electric sliding table 9 is provided inside the support base 3. A cylinder 5 and a welding head 7 are provided on one side of the electric sliding table 9. A pipeline component 8 is provided inside the support base 3. Further included are: An elimination component 6, which is fixedly connected to the cylinder 5 and is used for cleaning the dirt on the inner wall of the pipeline component 8; A screening component 4, which is located above the support base 3 and is used for filtering the cooling water in the pipeline component 8.

[0022] Furthermore; the upper end of the support frame 1 is slidably connected to the processing table 2. The support frame 1 is fixedly connected to the support base 3. The support base 3 is arranged in a "C" shape and is located in the middle of the support frame 1. A limit slide rail 31 is provided on the upper side wall of the support base 3. The electric sliding table 9 is slidably connected to the inner wall of the limit slide rail 31. A support rod one 91 is fixedly connected to the upper end of the electric sliding table 9. A support rod two 92 is fixedly connected to the lower side wall of the electric sliding table 9. There are two support rods one 91 and two support rods two 92. The height of the upper end of the support rod one 91 is higher than the height of the upper side wall of the support base 3. The end of the support rod two 92 away from the electric sliding table 9 is fixedly connected to the cylinder 5.

[0023] Welding of the photovoltaic bracket by the welding head 7: Before welding the photovoltaic bracket, the bracket is first placed on the processing table 2 for fixed assembly. The processing table 2 is a prior art and can be used to assemble and fix the bracket to avoid shaking and offset of the bracket during welding. Therefore, the specific fixing process is no longer described in detail. After fixation, the processing table 2 can be controlled by the electric control equipment to move toward the support seat 3 at the upper end of the support frame 1. This process is also a prior art, so it is no longer described in detail. After the bracket on the processing table 2 is moved to the appropriate position, the electric slide 9 is controlled to slide inside the limiting slide rail 31 according to the welding point to adjust the welding position of the welding head 7, and then the cylinder 5 is controlled to work, and finally the welding head 7 is driven to move down to weld the welding points of the bracket, so as to complete the assembly welding of the bracket. In addition, the reason why the height of the support rod 91 is set higher than the height of the support seat 3 is because the screening component 4 can be smoothly driven to move synchronously during the movement of the electric slide 9 to better cooperate with the operation of the equipment.

[0024] Reference Figure 6-Figure 9 , further; the pipeline assembly 8 includes a telescopic tube 81, a spiral cooling tube 82 and a telescopic tube 83, the spiral cooling tube 82 is sleeved on the outer wall of the welding head 7, both ends of the spiral cooling tube 82 are fixedly connected to the side walls of the support plate 61, one end of the telescopic tube 81 is fixedly connected to the side wall of the water tank 42, the connection between the telescopic tube 81 and the water tank 42 is located above the scraper 421, the other end of the telescopic tube 81 is fixedly connected to one end of the spiral cooling tube 82, one end of the telescopic tube 83 is fixedly connected to the water pump 45, the other end of the telescopic tube 83 is fixedly connected to the connecting box 64, one side of the connecting box 64 is fixedly connected to one end of the spiral cooling tube 82, and the outer wall of the spiral cooling tube 82 is connected to the end of the one-way drainage pipe 63 away from the water pump 2 66.

[0025] Use of the pipe assembly 8: In the initial state, a certain amount of cooling water is installed inside the water tank 42, and the water level is lower than the scraper 421. During the welding process of the bracket, the water pump 45 can be started to transport the cooling water inside the water tank 42 to the inside of the spiral cooling pipe 82 through the telescopic pipe 2 83 and the connection box 64. The high temperature generated by the welding head 7 during welding is cooled by the flow of the spiral cooling pipe 82 to ensure the use of the welding head 7. After the continuous flow of cooling water, it flows back to the inside of the water tank 42 through the telescopic pipe 1 81. The cooling of the welding head 7 is achieved through the circulation of cooling water. The telescopic pipe 1 81 and the telescopic pipe 2 83 are both made of rubber material. It has good wear resistance, corrosion resistance, and elasticity. Therefore, in the process of the cylinder 5 driving the welding head 7 to move downward, it can ensure the flow of liquid inside the pipeline and ensure the implementation of the cooling effect. In addition, the spiral cooling tube 82 can be made of stainless steel. Stainless steel contains alloy elements such as chromium and nickel. Chromium can form a dense chromium oxide protective film on the surface of the steel to prevent oxygen, moisture, etc. from further corroding the steel. Its high temperature resistance and corrosion resistance are used to ensure the normal operation of the equipment. The stainless steel pipeline also has a certain mechanical strength, can withstand the pressure of the coolant flowing, and is not easy to break; at the same time, it also has good toughness, and will not break brittlely when subjected to slight external force impact.

[0026] Furthermore, the elimination component 6 includes a support plate 61, a liquid storage box 62 and a connection box 64, the support plate 61 is fixedly connected to the end of the cylinder 5 away from the electric slide 9, one end of the support plate 61 is fixedly connected to the end of the connecting rope 44 away from the winding disk 43, the side walls of the support plate 61 are fixedly connected to the liquid storage box 62 and the connection box 64 respectively, the liquid storage box 62 is located on one side of the connection box 64, and the lower side wall of the support plate 61 is fixedly connected to the welding head 7; the interior of the liquid storage box 62 is fixedly connected to a water pump 66, one end of the water pump 66 is fixedly connected to a one-way drain pipe 63, one side of the liquid storage box 62 is fixedly connected to a connecting tube 65, and the end of the connecting tube 65 away from the liquid storage box 62 is fixedly connected to the connection box 64, A pressure sensor 68 is provided inside the connecting tube 65, and the pressure sensor 68 is fixedly connected to the side wall of the liquid storage box 62; a reset spring 67 and an extrusion block 69 are provided inside the connecting tube 65, and the extrusion block 69 is arranged in a "T" shape. One end of the reset spring 67 is fixedly connected to the side wall of the extrusion block 69, and the other end of the reset spring 67 is fixedly connected to the side wall of the liquid storage box 62. The reset spring 67 is located on the outside of the pressure sensor 68, and a limiting ring 610 is provided on the side of the extrusion block 69 away from the pressure sensor 68. The limiting ring 610 is fixedly connected to the inner wall of the connecting tube 65, and the inner diameter of the limiting ring 610 is smaller than the outer diameter of one end of the extrusion block 69. One end of the extrusion block 69 is slidably connected to the inner wall of the connecting tube 65.

[0027] Eliminator 6 removes impurities from the inner wall of the spiral cooling tube 82: Under normal circumstances, due to the normal use of the pipeline assembly 8, the water pressure inside the adapter box 64 is constant, and the extrusion block 69 will not be squeezed. Then the spiral cooling tube 82 directly absorbs the high temperature of the welding head 7. Therefore, in the environment where the spiral cooling tube 82 is heated, some substances in the cooling water are prone to form insoluble scale such as calcium carbonate and magnesium hydroxide. As time accumulates, the scale continues to thicken, causing the inner diameter of the water pipe to gradually shrink, seriously hindering the circulation of the coolant. Therefore, at this time, due to the blockage of the pipeline, the water discharge capacity of the water pump 45 is certain, so the adapter box 6 The water pressure inside the connecting tube 65 will gradually increase, and the pressure will cause the extrusion block 69 to move toward the side of the liquid storage box 62, compress the return spring 67, and the extrusion block 69 will slide with the inner wall piston of the connecting tube 65, and the side wall of the connecting tube 65 is provided with an air inlet and outlet hole, which can discharge the air inside the connecting tube 65 when the extrusion block 69 moves, so as to ensure the smooth movement of the extrusion block 69, and the size of the extrusion block 69 will cover the air outlet hole, so as to ensure that the cooling liquid will not be discharged from the connecting tube 65. When the water pressure reaches a certain range, one end of the extrusion block 69 will squeeze the pressure sensor 68, and the pressure sensor 68 is respectively connected to the water pump There is electrical connection between the first pump 45 and the second pump 66, so when the pressure sensor 68 detects the pressure, the first pump 45 is turned off and the second pump 66 is turned on to release the chemical solution stored in the liquid storage box 62 into the spiral cooling tube 82 through the one-way drain pipe 63, and the released chemical solution can diffuse into the cooling water. After the first pump 45 is turned off, the liquid no longer circulates, so the chemical solution can be soaked in the spiral cooling tube 82 for a certain period of time. For scale mainly composed of calcium carbonate, an appropriate amount of dilute hydrochloric acid solution can be used to inject the acid cleaning agent into the cooling water pipe and soak it for a period of time to allow the acid to react chemically with the scale. After dissolving it, the water pump 45 is restarted, and the inner wall of the spiral cooling tube 82 is repeatedly rinsed by the flow of cooling water, so as to reduce the attachment of impurities to the inner wall of the spiral cooling tube 82, ensure the cooling effect of the welding head 7, and avoid the welding head 7 being in a high temperature environment for a long time, so that the material performance of the key components such as the internal electrode and the conductive nozzle is rapidly degraded. By timely heat dissipation and temperature reduction, the thermal damage of these components is slowed down and the service life is extended. At this time, the water pressure inside the connection box 64 is reduced, and the elastic recovery of the reset spring 67 separates the extrusion block 69 from the pressure sensor 68 to wait for the next cleaning work; If coolant is used in the water tank 42, its chemical composition will change after long-term use, such as oxidation decomposition, generating some sticky substances or precipitates. These deteriorated products not only cannot play a normal cooling role, but also adhere to the water pipes, causing the water pipes to be blocked. Therefore, it is more appropriate to use an alkaline cleaning agent inside the liquid storage box 62, such as alkaline solutions such as sodium hydroxide and sodium carbonate, which can saponify grease, decompose microorganisms, and turn the blockage into a water-soluble substance. Finally, the pipeline can be cleaned. The liquid storage box 62 can be made of glass, which can not only intuitively understand the use of the solution, but also has corrosion resistance, and the solution can be replenished through the liquid filling pipe of the liquid storage box 62 itself. In addition, in order to ensure the cleaning effect, the liquid inside the liquid storage box 62 can be drained through the water pump 2 66, and then replenished. The setting of the limit ring 610 is to limit the position of the extrusion block 69 during the resetting process to avoid its separation from the connecting tube 65 to ensure the subsequent use effect.

[0028] Example 2, refer to Figure 1-Figure 9 , further; the screening component 4 includes a water tank 42, the upper end of the water tank 42 is detachably connected to a cover plate 41, the inner wall of the water tank 42 is fixedly connected to a scraper 421, two scrapers 421 are provided, and the two scrapers 421 are respectively fixedly connected to the inner walls of the water tank 42 on both sides symmetrically, and one end of the screening component 4 is fixedly connected to a water pump 45; the screening component 4 also includes a winding disk 43 and a filter cartridge 46, the filter cartridge 46 is rotatably connected to the inner wall of the water tank 42, the outer wall of the filter cartridge 46 is in contact with one end of the scraper 421, and one end of the filter cartridge 46 is fixedly connected to a fixed shaft 461, and the end of the fixed shaft 461 away from the filter cartridge 46 passes through the side wall of the water tank 42 and is fixedly connected to the winding disk 43.

[0029] Filtering of impurities by the filter cartridge 46: When the water pump 45 is started to flush the spiral cooling tube 82, the liquid containing impurities will flow back to the inside of the water tank 42 through the telescopic tube 81, and then be filtered by the filter cartridge 46 for reuse, so as to reduce the waste of resources and improve the utilization effect. Moreover, the detachable connection between the water tank 42 and the cover plate 41 allows the cover plate 41 to be quickly disassembled, thereby facilitating the cleaning of impurities accumulated inside the water tank 42 to ensure the filtering effect. Moreover, when new cooling liquid is added to the inside of the water tank 42 through the cover plate 41, it can also be filtered through the filter cartridge 46 to improve the cooling effect.

[0030] Furthermore, a torsion spring 47 is sleeved on the outer wall of one end of the fixed shaft 461 located outside the water tank 42, one end of the torsion spring 47 is fixedly connected to the side wall of the water tank 42, and the other end of the torsion spring 47 is fixedly connected to the side wall of the winding drum 43. A connecting rope 44 is provided on the inner side of the winding drum 43, and one end of the connecting rope 44 is fixedly connected to the winding drum 43.

[0031] The connecting rope 44 and the scraper 421 cooperate with each other to clean the filter cartridge 46: when the cylinder 5 drives the welding head 7 to move downward, the support plate 61 will also be driven to move synchronously. At this time, the connecting rope 44 wound inside the winding disk 43 is pulled and released, thereby driving the filter cartridge 46 to rotate inside the water tank 42 through the fixed shaft 461. At this time, the impurities attached to the surface of the filter cartridge 46 can be cleaned through the scraper 421 to reduce the blockage of the filter cartridge 46 to improve the filtering effect, and a soft brush can be provided at the contact point between the scraper 421 and the filter cartridge 46 to ensure the cleaning effect. While the filter cartridge 46 rotates, the torsion spring 47 will undergo elastic deformation. When the cylinder 5 drives the welding head 7 to rise, the elastic recovery of the torsion spring 47 allows the winding disk 43 to rewind the connecting rope 44 and drive the filter cartridge 46 to reverse. The filter cartridge 46 can be cleaned again through the scraper 421. In addition, the connecting rope 44 can be made of wear-resistant and high-temperature resistant materials, such as carbon fiber rope or steel wire rope, but is not limited to this.

The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
