Description

Technical Field

[0001] The invention relates to the field of photovoltaic modules, in particular to a surface treatment device and process for an aluminum alloy frame of a photovoltaic module. Background Art

[0002] Photovoltaic modules generally refer to solar cell modules, which are composed of high-efficiency crystalline silicon solar cells, ultra-white cloth-textured tempered glass, EVA, transparent TPT backplane and aluminum alloy frame. The aluminum alloy frame is installed on the solar panel to protect and support the solar photovoltaic panel. Since the solar panel is used outdoors and encounters harsh weather conditions, corrosion resistance and oxidation resistance are very important, so the aluminum alloy frame needs to be sandblasted.

[0003] There are still the following problems in the process of sandblasting of aluminum alloy frames:

[0004] 1. After the aluminum alloy frame is sandblasted, the traditional method is to manually clean the sand remaining on the surface of the aluminum alloy frame after sandblasting, which is cumbersome and increases the labor force.

[0005] 2. During the sandblasting process of the aluminum alloy frame, the traditional method is to place the aluminum alloy frame to be processed directly on the transmission device. The direction of the aluminum alloy frame is difficult to control during transportation, and the aluminum alloy frame is prone to displacement during the sandblasting process, which affects the sandblasting effect of the photovoltaic frame.

[0006] 3. During the sandblasting process of the aluminum alloy frame, the traditional nozzle swings in an arc shape in the sandblasting room. During the swinging process, the distance between the nozzle and the aluminum alloy frame that needs to be sandblasted is unstable. The sandblasting intensity of the frame located in the center of the sandblasting room is stronger, while the sandblasting intensity of the frames located on both sides of the sandblasting room is weaker, so the problem of poor sandblasting effect will occur.

[0040] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described.

[0041] Refer to Figure 1 , a surface treatment device for an aluminum alloy frame of a photovoltaic module, including a workbench 1, a moving device 2 and a transmission device 3. A moving device 2 is arranged on the top of the workbench 1, and a transmission device 3 is arranged on the moving device 2;

[0042] Refer to Figure 2, the mobile device 2 includes a vertical plate 21, a C-shaped plate 22, a first fixed baffle 23, a second fixed baffle 24, a sandblasting assembly 25, an electric push rod 26, a structural plate 27, a cleaning assembly 28, and a jetting assembly 29. On the top of the workbench 1, vertical plates 21 are symmetrically and fixedly installed on the front and rear sides. At the position near the right side of the tops of the front and rear vertical plates 21, a C-shaped plate 22 with an open bottom is fixedly installed. A rectangular through groove is opened at the position near the right side of the vertical section of the front end face of the C-shaped plate 22, and a transparent door panel is fixedly installed in the rectangular through groove. Two first fixed baffles 23 are fixedly installed at the position near the left side of the bottom of the horizontal section of the C-shaped plate 22. A second fixed baffle 24 is fixedly installed at the position on the bottom of the horizontal section of the C-shaped plate 22 and to the right of the first fixed baffle 23. A sandblasting assembly 25 is arranged between the two first fixed baffles 23 at the bottom of the horizontal section of the C-shaped plate 22. An electric push rod 26 is fixedly installed between the first baffle and the second baffle at the bottom of the horizontal section of the C-shaped plate 22. The bottom of the electric push rod 26 is fixedly installed with a structural plate 27. A cleaning assembly 28 is arranged on the left side of the structural plate 27, and a jetting assembly 29 is arranged on the right side of the structural plate 27.

[0043] In the original state, first, the aluminum alloy frames of the photovoltaic modules to be processed are batch-placed on the transmission device 3. The transmission device 3 transports the aluminum alloy frames of the photovoltaic modules to be processed. During the transportation, when the aluminum alloy frames of the photovoltaic modules to be processed are transported below the sandblasting assembly 25, first, the sandblasting assembly 25 performs sandblasting on the aluminum alloy frames of the photovoltaic modules to be processed. During the sandblasting process, the first fixed baffle 23 plays an isolation role to prevent dust from floating out during the sandblasting process and thus affecting the working environment. After the aluminum alloy frames of the photovoltaic modules are processed, the transmission device 3 drives the sandblasted aluminum alloy frames of the photovoltaic modules to continue moving. When the aluminum alloy frames of the photovoltaic modules to be processed are transported below the cleaning assembly 28 and the jetting assembly 29, the cleaning assembly 28 and the jetting assembly 29 quickly clean the remaining sand on the surface of the sandblasted aluminum alloy frames of the photovoltaic modules, avoiding the problems of not only cumbersome operation but also increased labor caused by separately cleaning the sand later. The transparent door panel provided in the present invention is beneficial for observing the processing process of the aluminum alloy frames of the photovoltaic modules.

[0044] Refer to Fig. 9, the adjusting assembly 36 includes an adjusting plate 361, a sliding plate 362, a swinging plate 363, a return spring 364, a U-shaped block 365, a moving plate 366, a rectangular plate 367 and a compression spring 368. One end of each of the two adjusting plates 361 is fixedly installed with a sliding plate 362. A swinging plate 363 is hinged to the sliding plate 362 through a pin shaft. The two swinging plates 363 are hinged to each other, and the two swinging plates 363 are connected by a return spring 364. A sliding groove is formed at one end of the sliding plate 362 away from the adjusting plate 361. A U-shaped block 365 is arranged at one end of the sliding plate 362 away from the adjusting plate 361. The two vertical sections of the U-shaped block 365 are slidably arranged in the sliding groove. A moving plate 366 is slidably arranged in the middle of the horizontal section of the U-shaped block 365. One end of the moving plate 366 is rotatably connected to the hinge joint of the two swinging plates 363. The other end of the moving plate 366 is fixedly installed with a rectangular plate 367. The rectangular plate 367 and the horizontal section of the U-shaped block 365 are connected by a compression spring 368.

[0045] Refer to Figure 3 , Figure 4 and Figure 8 , the limiting assembly 35 includes a first electromagnet 351, an inverted L-shaped plate 352, a second electromagnet 353, a receiving plate 354, a second spring rod 355 and a circular bead 356. The first electromagnet 351 is fixedly installed in the limiting groove. The inverted L-shaped plates 352 are symmetrically and slidably arranged in the front and back in the limiting groove. A second electromagnet 353 is fixedly installed at the bottom of the vertical section of the inverted L-shaped plate 352. Displacement grooves are formed on the opposite surfaces of the two horizontal sections of the inverted L-shaped plate 352. A receiving plate 354 is slidably arranged in the two displacement grooves together. Arc-shaped clamping grooves are symmetrically and evenly formed on the upper and lower sides of the front and rear ends of the receiving plate 354. A plurality of circular grooves are evenly formed on the upper and lower sides in the displacement groove. Circular beads 356 are fixedly installed in the circular grooves through the second spring rods 355.

[0046] First, adjust the distance between the two inverted L-shaped plates 352 in the limit slot according to the different widths of the aluminum alloy frames of the photovoltaic modules to be processed. When adjusting the distance between the two inverted L-shaped plates 352, the first electromagnet 351 and the second electromagnet 353 are de-energized. At this time, place the two adjusting plates 361 between the two inverted L-shaped plates 352. After placing them, push the rectangular plate 367. The rectangular plate 367 squeezes the compression spring 368. At the same time, the rectangular plate 367 drives the moving plate 366 to push the swing plate 363 to move. The swing plate 363 causes the adjusting plate 361 to slide in the sliding groove on the sliding plate 362. At this time, the adjusting plate 361 adjusts the distance between multiple groups of two inverted L-shaped plates 352 at the same time. During the adjustment process, the receiving plate 354 moves in the displacement groove in the inverted L-shaped plate 352. After the adjustment is completed, under the action of the second spring rod 355, the circular bead 356 is clamped into the arc-shaped card slot on the receiving plate 354, thereby limiting the inverted L-shaped plate 352. When the limiting is completed, the first electromagnet 351 and the second electromagnet 353 are energized, so that the first electromagnet 351 and the second electromagnet 353 attract each other, thereby limiting the inverted L-shaped plate 352.

[0047] Refer to Figure 7 The sandblasting assembly 25 includes an electric telescopic rod 251, a square hollow plate 252, an annular rod 253, and a U-shaped sandblasting head 254. An electric telescopic rod 251 is fixedly installed at the bottom of the horizontal section of the U-shaped plate 22 and between the two first fixed baffles 23. The bottom of the electric telescopic rod 251 is fixedly installed with a square hollow plate 252. The bottom of the square hollow plate 252 is fixedly installed with annular rods 253 that are connected in series from front to back. The bottom of the annular rod 253 is fixedly installed with a U-shaped sandblasting head 254 that is connected in series.

[0048] When the transmission device 3 drives the aluminum alloy frame of the photovoltaic module to be processed and transports it to the lower part of the sandblasting assembly 25, start the electric telescopic rod 251. The electric telescopic rod 251 drives the square hollow plate 252 to move downward, so that the annular rod 253 drives the U-shaped sandblasting head 254 to move to the side of the aluminum alloy frame of the photovoltaic module to be processed. Through the provided U-shaped sandblasting head 254, the side walls of the aluminum alloy frame of the photovoltaic module to be processed can be sandblasted at the same time, preventing the problem of uneven sandblasting on the surface of the aluminum alloy frame of the photovoltaic module, thereby affecting the sandblasting effect on the aluminum alloy frame of the photovoltaic module.

[0049] Refer to Figure 2 、 Figure 3 and Fig. 9The transmission device 3 includes a rotating rod 31, a fixed sprocket 32, a mobile chain 33, a horizontal plate 34, a limit assembly 35, an adjustment assembly 36 and a transmission assembly 37. Two horizontally arranged rotating rods 31 are rotatably arranged near the left side between the two vertical plates 21. A mounting plate is fixedly installed on the vertical plate 21 on the rear side. The mounting plate is an L-shaped plate. A driving motor is fixedly installed on the mounting plate. The output shaft of the driving motor is fixedly connected to one end of the rotating rod 31. Fixed sprockets 32 are evenly fixedly installed on the two rotating rods 31 from front to back. The fixed sprockets 32 arranged from left to right are all connected by the mobile chain 33. The side walls of multiple mobile chains 33 are commonly fixedly installed with horizontal plates 34. The horizontal plates 34 are evenly distributed along the circumference of the mobile chain 33, and the top of the horizontal plates 34 is evenly provided with limit grooves from front to back. The limit grooves are provided with limit assemblies 35, and the workbench 1 is also provided with an adjustment assembly 36. A transmission assembly 37 is provided near the right side between the two vertical plates 21.

[0050] First, the setting adjustment component 36 is used to adjust the limiting component 35 according to the different widths of the aluminum alloy frames of the photovoltaic components to be processed. After the adjustment is completed, the aluminum alloy frames of the photovoltaic components to be processed are placed in batches on the limiting component 35 on the transmission device 3, and the setting limiting component 35 is used to limit the aluminum alloy frames of the photovoltaic components to be processed, so as to avoid the waste of manpower and material resources caused by manual assistance during the transportation of the aluminum alloy frames of the photovoltaic components, and avoid the problem of difficult control of the direction during transportation, which affects the sandblasting efficiency and sandblasting effect of the aluminum alloy frames of the photovoltaic components. As a result, after the aluminum alloy frames of the photovoltaic components that need to be processed are placed in batches on the limit assembly 35 on the transmission device 3, the drive motor is started, and the drive motor drives the rotating rod 31 to rotate, and the rotating rod 31 drives the fixed sprocket 32 ​​to rotate. At this time, under the action of the moving chain 33, the limit assembly 35 on the horizontal plate 34 drives the aluminum alloy frames of the photovoltaic components to be transported. After the sandblasting of the aluminum alloy frames of the photovoltaic components is completed, the limit assembly 35 on the horizontal plate 34 drives the aluminum alloy frames of the photovoltaic components to be transported to the transmission assembly 37, and the aluminum alloy frames of the photovoltaic components can be supported by the transmission assembly 37.

[0051] See also Figure 3 The transmission assembly 37 includes a rotating rod 371, a rubber pad 372 and a limiting circular plate 373. A plurality of rotating rods 371 are evenly rotated and arranged near the right side between the two vertical plates 21. Rubber pads 372 are fixedly installed on the plurality of rotating rods 371. A plurality of groups of limiting circular plates 373 are evenly fixedly installed on the rotating rods 371 from front to back, and each group of limiting circular plates 373 has two.

[0052] When the transmission device 3 drives the aluminum alloy frame of the photovoltaic module after sandblasting to be transported, the aluminum alloy frame of the photovoltaic module is transported to the rotating rod 371. The rubber pad 372 arranged on the rotating rod 371 can increase the friction force, thereby driving the aluminum alloy frame of the photovoltaic module to move to the right. The aluminum alloy frame of the photovoltaic module can be supported by the rotating rod 371, and the aluminum alloy frame of the photovoltaic module can be limited by the limiting circular plate 373.

[0053] See also Figure 3 and Figure 5 The cleaning assembly 28 includes a clamping plate 281, a clamping block 282, a connecting block 283, a square plate 284 and a brush 285. A rectangular groove is provided on the left side of the bottom of the structural plate 27. The clamping plate 281 is fixedly installed on the inner side wall of the left end of the rectangular groove through a plurality of No. 1 spring rods. A clamping block 282 is fixedly installed between the right end surface of the clamping plate 281 and the inner side wall of the right end of the rectangular groove.

A square plate 284 is fixedly installed on the bottom of the connecting block 283. A brush 285 is fixedly installed on the bottom of the square plate 284.

[0054] See also Figure 3 and Figure 6 The jet assembly 29 includes an air pump 291, a connecting pipe 292, a jet cavity 293, a sliding groove 294, a fixed mesh plate 295 and filter cotton 296. The air pump 291 is fixedly installed on the top right side of the structural plate 27, and a connecting pipe 292 is fixedly installed on the structural plate 27 near the right side. The top of the connecting pipe 292 is connected to the air outlet of the air pump 291. The jet cavity 293 is fixedly installed at the bottom of the structural plate 27 and below the connecting pipe 292. A sliding groove 294 is opened at the bottom of the jet cavity 293. A fixed mesh plate 295 is slidably arranged in the sliding groove 294, and a filter cotton 296 is fixedly installed at the bottom of the fixed mesh plate 295.

[0055] When the transmission device 3 drives the aluminum alloy frame of the photovoltaic module after sandblasting and transports it below the cleaning component 28, the electric push rod 26 is started. The electric push rod 26 drives the structural plate 27 to move downward. The structural plate 27 causes the connecting block 283 to drive the square plate 284 to move downward. The square plate 284 drives the brush 285 to quickly clean the remaining sand on the surface of the aluminum alloy frame of the photovoltaic module. By setting the connecting block 283 to be detachable, it is convenient to quickly replace the damaged brush 285. When the aluminum alloy frame of the photovoltaic module continues to move to the right, the air pump 291 is started. The air pump 291 inflates, and the gas enters the jet cavity 293 through the connecting pipe 292, thereby cleaning the remaining sand on the surface of the aluminum alloy frame of the photovoltaic module again, avoiding the problems of not only cumbersome operation but also increased labor caused by separately cleaning the sand later. By setting the filter cotton 296, it can prevent sand from entering the jet cavity 293 during the process of cleaning the sand.

[0056] Refer to Figure 2 At the position near the right side of the top of the workbench 1, a collection box 11 is fixedly installed;

[0057] Through the set collection box 11, the sand after cleaning can be collected and processed, which can not only avoid the phenomenon of dirty, messy and poor working environment, but also recycle the collected sand;

[0058] The present invention also provides a surface treatment process for the aluminum alloy frame of a photovoltaic module. The specific treatment process includes the following steps:

[0059] S1. Frame transportation: First, use the set adjustment component 36 to adjust the limit component 35 according to the different widths of the aluminum alloy frames of the photovoltaic modules to be processed. After adjustment, place the aluminum alloy frames of the photovoltaic modules to be processed in batches on the limit component 35 on the transmission device 3. After placement, start the drive motor. The drive motor drives the rotating rod 31 to rotate. The rotating rod 31 drives the fixed sprocket 32 to rotate. At this time, under the action of the moving chain 33, the limit component 35 on the horizontal plate 34 drives the aluminum alloy frames of the photovoltaic modules to be transported.

When the aluminum alloy frame of the photovoltaic module continues to move to the right, the air pump 291 is started, and the air pump 291 is inflated. The gas enters the jet cavity 293 through the connecting pipe 292, and then the sand remaining on the surface of the aluminum alloy frame of the photovoltaic module is cleaned again, so as to avoid the problem of cumbersome operation and increased labor caused by sand cleaning alone at a later time.
