Description
Technical Field
[0001] This utility model relates to the field of photovoltaic ribbon technology; more specifically, it relates to a coating device for anti-oxidation treatment of photovoltaic ribbon surface. Background Technology
[0002] Photovoltaic solder ribbon is a key material for photovoltaic modules, typically made of tin-plated copper strip with a thickness of 0.1-0.3mm, used to connect solar cells in series to form a circuit. It needs to possess good conductivity, tensile strength, and weather resistance. Connecting the cell electrodes through high-temperature soldering directly affects the module's power output and reliability. Based on application, it is divided into busbars and interconnecting strips; the former is thicker, while the latter is thinner. Some use low-temperature solder ribbon to reduce heat damage.
[0003] The coating device for anti-oxidation treatment of photovoltaic solder ribbon is a special equipment used to improve the weather resistance of solder ribbon. Its core function is to cover the surface of the solder ribbon by precisely applying an anti-oxidation coating such as a tin alloy layer or an organic protective film to isolate it from oxygen and moisture corrosion.
[0004] Currently, existing coating devices require the uncoated photovoltaic (PV) ribbon to be wound onto the outer surface of a unwinding shaft before coating. Once the ribbon on the outer surface of the unwinding shaft is used up, it needs to be replaced for recoating. However, most existing devices require the unwinding shaft to be fitted onto the outer surface of a winding frame, making installation cumbersome and reducing the device's practicality. Furthermore, existing devices often handle PV ribbons of varying widths, and the clamping and transmission structures of most devices are of fixed dimensions, making it difficult to adjust the clamping and transmission distance according to the actual thickness of the PV ribbon, further reducing applicability. Therefore, a coating device for anti-oxidation treatment of PV ribbon surfaces is urgently needed to solve these problems. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a coating device for anti-oxidation treatment of photovoltaic ribbon surface, so as to solve the problems existing in the background art.
[0006] This utility model provides the following technical solution: a coating device for anti-oxidation treatment of photovoltaic welding strip surface, comprising: a base, a quick-installation structure provided on the outer surface of one upper end of the base, and an adjustment structure provided on the outer surface at the middle position of the upper end of the base; a spray box installed on the outer surface of the other upper end of the base, and a liquid storage tank fixedly connected to the upper end of the spray box; the quick-installation structure includes a support column, a mounting groove, a rotating shaft, a movable groove, a movable plate, a first spring, and a stop block; the adjustment structure includes a support plate, a support rod, a motor, a transmission shaft, a moving groove, a positioning hole, a fixing rod, a connecting sleeve, a pulling block, a second spring, and a positioning column.
[0007] Preferably, the support columns are provided in two sets, and the lower ends of the two sets of support columns are respectively fixedly connected to the outer surfaces of the upper end of the base on both sides. The upper outer surfaces of the two sets of support columns are provided with mounting grooves, and rotating shafts are inserted into the mounting grooves. The inner walls of both sides of the mounting grooves are provided with movable grooves, and movable plates are engaged with the movable grooves. A first spring is provided inside the movable grooves, and a stop block is inserted inside the mounting grooves. This design allows the movable plates to move inside the movable grooves.
[0008] Preferably, the two ends of the first spring abut against the surface of one side of the movable plate and the inner wall surface of the movable groove, respectively. Rectangular blocks are fixedly connected to the inner wall surfaces of the upper and lower ends of the movable groove. Rectangular grooves are opened inside the outer surfaces of the upper and lower ends of the movable plate, and the internal dimensions of the rectangular grooves are adapted to the external dimensions of the rectangular blocks. This design allows the movable plate to automatically reset under the elasticity of the first spring after moving inside the movable groove.
[0009] Preferably, an insertion block is fixedly connected to the outer surface of the other side of the movable plate. Insertion slots are provided inside the outer surfaces of both sides of the block, and the internal dimensions of the insertion slots are adapted to the external dimensions of the insertion block. This design makes the insertion block more stable when inserted into the insertion slot, thereby making the block more stable when inserted into the mounting slot.
[0010] Preferably, the bottom of the support plate is fixedly connected to the outer surface of the upper middle position of the base, and support rods are fixedly connected to the outer surfaces of both ends of the upper end of the support plate. A motor is installed on the outer surface of one of the lower ends of the two sets of support rods, and a drive shaft is fixedly connected to the output end of the motor. A moving groove is opened inside the upper outer surface of both sets of support rods, and positioning holes are opened inside the outer surfaces on both sides of the moving groove of one of the two sets of moving grooves. Multiple sets of positioning holes are provided. A fixed rod is slidably connected inside the two sets of moving grooves. A connecting sleeve is opened inside the outer surface of one end of the fixed rod, and a pulling block is inserted inside the connecting sleeve. An insertion rod is fixedly connected to the outer surface of the middle position of one side of the pulling block, and a second spring is sleeved on the outer surface of one end of the insertion rod. Positioning pins are fixedly connected to the outer surfaces of both ends of one side of the pulling block, and a rotating sleeve is sleeved on the outer surface of the fixed rod. This design allows the fixed rod to move up or down inside the moving groove.
[0011] Preferably, one end of the insertion rod is fixedly connected to a limiting ring, and the external dimensions of the limiting ring are adapted to the internal dimensions of the connecting sleeve. The two ends of the second spring abut against the surface of one side of the limiting ring and the inner wall surface of the connecting sleeve, respectively. This design makes the pulling block more stable when it moves inside the connecting sleeve.
[0012] Preferably, the inner wall surfaces of the upper and lower ends of the connecting sleeve are provided with guide grooves, and the outer surfaces of the upper and lower ends of the limiting ring are fixedly connected with guide blocks. The external dimensions of the guide blocks are adapted to the internal dimensions of the guide grooves. This design ensures that the pulling block will not deflect when it moves inside the connecting sleeve.
[0013] Preferably, the external dimensions of the positioning post are adapted to the internal dimensions of the positioning hole, which makes the positioning post more stable when inserted into the positioning hole.
[0014] The technical effects and advantages of this utility model are as follows: By pushing the movable plate outward, the insertion block on the other side of the movable plate is disengaged from the insertion slot. Then, two sets of stop blocks can be removed from the two sets of mounting slots. Subsequently, the rotating shaft can be removed from the two sets of mounting slots. At this time, the unused rotating shaft can be placed inside the two sets of mounting slots. Then, the stop block can be inserted into the mounting slot. Then, the movable plate can be released, allowing the movable plate to return to its original position under the elasticity of the first spring. This allows the insertion block on the other side of the movable plate to be inserted into the insertion slot. This allows the position of the stop block inside the mounting slot to be positioned, and the position of the rotating shaft inside the mounting slot to be positioned. This makes it more convenient to install the rotating shaft inside the mounting slot, thereby improving the practicality of the device to a certain extent. By pulling the pull block outward, the positioning post is disengaged from the positioning hole. At this time, the position of the fixed rod can be moved up or down inside the moving groove. This allows the distance between the drive shaft and the fixed rod to be adjusted according to the actual thickness of the photovoltaic welding strip, thus avoiding mismatch and improving the applicability of the device to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The photovoltaic welding ribbon involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Example 1, as Figures 1-5As shown, this embodiment proposes a coating device for anti-oxidation treatment of photovoltaic welding strip surface, including: a base 1, a quick-installation structure 2 provided on the outer surface of one upper end of the base 1, and an adjustment structure 3 provided on the outer surface of the middle position of the upper end of the base 1; a spray box 4 is installed on the outer surface of the other upper end of the base 1, and a liquid storage tank 5 is fixedly connected to the upper end of the spray box 4; the quick-installation structure 2 includes a support column 21, a mounting groove 22, a rotating shaft 23, a movable groove 24, a movable plate 25, a first spring 26, and a stop block 27; two sets of support columns 21 are provided, and the lower ends of the two sets of support columns 21 are respectively fixedly connected to the outer surfaces of both sides of one upper end of the base 1; the inner surface of the upper outer surface of both sets of support columns 21 is provided with a mounting groove 22, and a rotating shaft 23 is inserted into the inner surface of the mounting groove 22; the inner surface of the inner wall of both sides of the mounting groove 22 is provided with a... The movable groove 24 is fitted with a movable plate 25, and a first spring 26 is provided inside the movable groove 24. A stop block 27 is inserted inside the mounting groove 22. The two ends of the first spring 26 abut against one side of the movable plate 25 and the inner wall surface of the movable groove 24, respectively. Rectangular blocks are fixedly connected to the inner wall surfaces of the upper and lower ends of the movable groove 24. Rectangular grooves are opened inside the outer surfaces of the upper and lower ends of the movable plate 25, and the internal dimensions of the rectangular grooves are adapted to the external dimensions of the rectangular blocks. This design allows the movable plate 25 to return to its original position under the elasticity of the first spring 26 after moving inside the movable groove 24. This design also makes the movable plate 25 more stable when moving inside the movable groove 24, thereby preventing the movable plate 25 from detaching from the movable groove 24 when moving inside the movable groove 24. An insertion block is fixedly connected to the outer surface of the other side of the movable plate 25. Insertion slots are opened inside the outer surfaces of both sides of the stop block 27, and the internal dimensions of the insertion slots are adapted to the external dimensions of the insertion block. This design makes the insertion block more stable when inserted into the insertion slot, thereby positioning the stop block 27 inside the mounting slot 22, and thus preventing the rotating shaft 23 from dislodging from the mounting slot 22 when rotating.
[0023] Example 2, as Figure 4 and Figure 5As shown, based on the same concept as the above embodiment, this embodiment also proposes: the adjustment structure 3 includes a support plate 31, a support rod 32, a motor 33, a transmission shaft 34, a moving groove 35, a positioning hole 36, a fixing rod 37, a connecting sleeve 38, a pulling block 39, a second spring 310, and a positioning column 311. The bottom of the support plate 31 is fixedly connected to the outer surface at the middle position of the upper end of the base 1, and the outer surfaces at both ends of the upper end of the support plate 31 are fixedly connected to the support rod 32. A motor 33 is installed on the outer surface of one of the two sets of support rods 32 at the lower end. The output end of the motor 33 is fixedly connected to the transmission shaft 34. The inner surface of the upper end of the outer surface of both sets of support rods 32 is provided with a moving groove 35, and the inner surface of the outer surface on both sides of the moving groove 35 of one of the two sets of moving grooves 35 is provided with a positioning hole 36. Multiple sets of positioning holes 36 are provided. The inner surface of the two sets of moving grooves 35 is engaged and slidably connected to the fixing rod 37, and the fixing rod 37 is fixedly connected to the inner surface of the moving groove 35. A connecting sleeve 38 is provided inside the outer surface of one end of the fixed rod 37, and a pulling block 39 is inserted inside the connecting sleeve 38. A rotating sleeve is fitted on the outer surface of the fixed rod 37. An insertion rod is fixedly connected to the outer surface of the middle position on one side of the pulling block 39, and a second spring 310 is fitted on the outer surface of one end of the insertion rod. Positioning pins 311 are fixedly connected to the outer surfaces of both ends on one side of the pulling block 39. A limit ring is fixedly connected to one end of the insertion rod, and the external dimensions of the limit ring are adapted to the internal dimensions of the connecting sleeve 38. The two ends of the second spring 310 abut against the surface of one side of the limit ring and the inner wall surface of the connecting sleeve 38, respectively. This design makes the pulling block 39 more stable when it moves inside the connecting sleeve 38, and this design allows the pulling block 39 to return to its original position by the elasticity of the second spring 310 after it moves inside the connecting sleeve 38, so that the positioning pins 311 can be inserted into the positioning holes 36 at the corresponding positions. The inner surfaces of the upper and lower ends of the connecting sleeve 38 are provided with guide grooves, and the outer surfaces of the upper and lower ends of the limiting ring are fixedly connected with guide blocks. The outer dimensions of the guide blocks are matched with the inner dimensions of the guide grooves. This design avoids the situation where the pulling block 39 deflects when it moves inside the connecting sleeve 38, thereby preventing the position of the positioning post 311 from intersecting with the position of the positioning hole 36. The external dimensions of the positioning post 311 are matched with the internal dimensions of the positioning hole 36. This design makes the positioning post 311 more stable when inserted into the positioning hole 36, thus facilitating the positioning of the working height of the fixing rod 37. The two sets of pull blocks 39 and the second spring 310 in this application, as well as all movable parts, require regular cleaning and maintenance, including but not limited to dust removal and lubrication.
[0024] Working principle: When using the device, by pushing the movable plate 25 outward, the insertion block on the other side of the movable plate 25 is disengaged from the insertion slot. Then, the two sets of stop blocks 27 can be removed from the two sets of mounting slots 22. Next, the rotating shaft 23 can be removed from the two sets of mounting slots 22. At this point, the unused rotating shaft 23 can be placed inside the two sets of mounting slots 22. Then, the stop blocks 27 can be inserted into the mounting slots 22, ensuring the position of the insertion block corresponds to the position of the insertion slot. Then, the movable plate 25 can be released, allowing it to automatically reset under the elasticity of the first spring 26. This allows the insertion block on the other side of the movable plate 25 to be inserted into the insertion slot, thus positioning the stop blocks 27 inside the mounting slots 22. This, in turn, positions the rotating shaft 23 inside the mounting slots 22, enabling quick replacement of the rotating shaft 23. Then, by pulling the pulling block 39 outward, the positioning pin 311 is disengaged from the positioning hole 36. At this point, the rotating shaft 23 can be quickly replaced inside the moving slot 35. The position of the fixed rod 37 can be moved up or down to adjust the distance between the drive shaft 34 and the fixed rod 37 according to the actual thickness of the photovoltaic welding strip. When the fixed rod 37 moves to a suitable position inside the moving groove 35, the pulling block 39 can be released, allowing the pulling block 39 to reset itself under the elasticity of the second spring 310. This allows the positioning post 311 to be inserted into the positioning hole 36 at the corresponding position, thereby positioning the fixed rod 37 in the moving groove 35. Then, the photovoltaic welding strip can be clamped inside the drive shaft 34 and the fixed rod 37. Subsequently, the motor 33 can be started, causing the output end of the motor 33 to drive the drive shaft 34 to rotate, thereby moving the photovoltaic welding strip inside the drive shaft 34 and the fixed rod 37. This allows the drive shaft 34 and the fixed rod 37 to transport the photovoltaic welding strip to the inside of the spray box 4. Then, the outer surface of the photovoltaic welding strip can be sprayed by the cooperation of the spray box 4 and the liquid storage tank 5. This is the entire working principle of this utility model.
