Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, specifically a diamond abrasive pad that can be quickly replaced at worn areas. Background Art

[0002] In the production process of photovoltaic modules, due to the small spacing between modules, a flattening function is used in the welding machine to ensure welding quality and module reliability. The effects of the flattening function are: 1. By flattening the welding strip or related connecting parts, the connection between the cells can be ensured to be tighter, reducing problems such as incomplete welding and false welding during the welding process, thereby improving welding quality; 2. By flattening the welding strip or connecting parts, the gap between the connecting parts of the cells can be reduced, reducing electrical losses, thereby improving the conversion efficiency of the photovoltaic module; 3. The flattened welding strip or connecting parts are also less susceptible to corrosion and damage from the external environment, thereby extending the service life of the photovoltaic module.

[0003] When the flattening function is used for a long time, the welding machine pad acts as a support to withstand the impact force generated by flattening. Therefore, the welding machine pad is prone to wear after long-term use, which affects the thickness of the weld strip after flattening.

[0004] Because traditional welding machine pads are integral structures, they need to be disassembled and replaced as a whole after wear. Since the positional accuracy requirements of welding machine pads are relatively high, their installation structure is relatively complex, making disassembly and assembly difficult. Moreover, replacing the entire pad is also relatively costly. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses a diamond abrasive pad that can be quickly replaced at worn areas.

[0006] This utility model provides a diamond abrasive pad that can be quickly replaced at worn areas, including a rectangular base plate;

[0007] The flattened stress area of ​​the base plate is provided with multiple non-circular insertion holes that extend vertically and are arranged linearly and evenly.

[0008] The metal block consists of a T-shaped insertion part and a force-bearing part. The shape of the insertion part is similar to that of the insertion hole and is inserted into the insertion hole. The force-bearing part protrudes upward from the base plate.

[0009] The beneficial effects of the above design are: 1. Since the force-bearing part protrudes upward from the base plate, the metal block becomes the force point for welding and flattening. Only the force-bearing part will wear, and the base plate will not wear; 2. When the force-bearing part wears, only the metal block needs to be replaced, without involving the disassembly and assembly of the base plate. The replacement efficiency is high and the cost is low; 3. The metal block can be disassembled and assembled by inserting and removing the metal block, which is simple and convenient to operate; 4. When there are positions of one or more metal blocks corresponding to the welding strip that do not need to be flattened, the metal blocks at the corresponding positions can be removed, making this utility model flexible and versatile in use and more applicable.

[0010] The shape of the connector directly affects its manufacturing difficulty. Based on this, a further design is to make the connector rectangular or square.

[0011] To further reduce the processing difficulty of the plug hole, specifically: the plug hole is a through hole.

[0012] Furthermore, the lower end of the metal block is higher than the bottom of the base plate.

[0013] The specific installation structure of the load-bearing part is as follows: the lower end face of the load-bearing part abuts against the upper end face of the base plate.

[0014] The stability of the metal block installation is poor when the plug-in part is locked to the plug-in hole alone. Therefore, the further improvement is that the plug-in hole is composed of an upper plug-in hole and a lower plug-in hole that are connected from top to bottom in a T-shape; the upper plug-in hole locks the force-receiving part; and the lower plug-in hole locks the plug-in part.

[0015] The required length precision for the flattening position of the welding strip is quite high. Using traditional metal blocks makes it difficult to control the flattening length. Therefore, a further improvement is made: a raised rectangular plate is installed at the center of the upper surface of the force-bearing part; the width of the plate is equal to the length of the section of the welding strip that needs to be flattened. This design, placing the welding strip on the plate parallel to its width direction, effectively controls the flattening length.

[0016] The protruding plate is generally integrally formed with the metal block and is usually machined by milling. To reduce the machining difficulty of the protruding plate, a further design is made: the two ends of the protruding plate in the length direction are flush with the side of the force-bearing part, and the two ends in the width direction are spaced apart from the other side of the force-bearing part.

[0017] The beneficial effects of this utility model are: 1. Since the force-bearing part protrudes upward from the base plate, the metal block becomes the force point for welding and flattening. Only the force-bearing part will wear, and the base plate will not wear; 2. When the force-bearing part wears, only the metal block needs to be replaced, without involving the disassembly and assembly of the base plate. The replacement efficiency is high and the cost is low; 3. The metal block can be disassembled and assembled by inserting and removing the metal block, which is simple and convenient to operate; 4. When there are positions of one or more metal blocks corresponding to the welding strip that do not need to be flattened, the metal blocks at the corresponding positions can be removed, making this utility model flexible and versatile in use and more applicable.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] like Figure 1 and Figure 2 As shown, this utility model discloses a quick-replaceable diamond abrasive pad for worn areas, comprising a cuboid base plate 1. The flattened stress area of ​​the base plate 1 is provided with multiple vertically extending, linearly and evenly spaced non-circular insertion holes 2. The insertion holes 2 are preferably rectangular or square for ease of processing. In this embodiment, the insertion holes 2 are square. Furthermore, the insertion holes 2 are designed as through holes for even easier processing.

[0026] A metal block 3 is engaged within the insertion hole 2. The metal block 3 consists of a T-shaped insertion part 31 and a force-receiving part 32, both of which are square in plan view. The insertion part 31 is shaped to match the insertion hole 2 and is inserted into it, with its lower end higher than the bottom of the base plate 1. The force-receiving part 32 protrudes upward from the base plate 1.

[0027] like Figure 3 and Figure 4 As shown, the insertion hole 2 is composed of an upper locking hole 21 and a lower locking hole 22 connected sequentially from top to bottom in a T-shape; the upper locking hole 21 engages with the force-receiving part 32; and the lower locking hole 22 engages with the insertion part 31. With this configuration, the structure of the metal block 3 has higher stability.

[0028] A rectangular protruding plate 33 is provided at the center of the upper end face of the force-bearing part 32; the width of the protruding plate 33 is equal to the length of the section of the welding strip that needs to be flattened. With this arrangement, the welding strip is placed on the protruding plate 33 in a manner parallel to the width direction, which can effectively control the flattening length of the welding strip.

[0029] To facilitate the forming of the protruding plate 33, the two ends of the protruding plate 33 in the length direction are flush with the side of the force-bearing part 32, and the two ends in the width direction are spaced apart from the other side of the force-bearing part 32.

[0030] The beneficial effects of the above-mentioned design are as follows: 1. Since the force-bearing part 32 protrudes upward from the base plate 1, the metal block 3 becomes the force point for welding flattening. Only the force-bearing part 32 will wear, and the base plate 1 will not wear. 2. When the force-bearing part 32 wears, only the metal block 3 needs to be replaced. There is no need to disassemble or reassemble the base plate 1. The replacement efficiency is high and the cost is low. 3. The metal block 3 can be disassembled and reassembled by inserting and removing the metal block 3. The operation is simple and convenient. 4. When there are positions of one or more metal blocks 3 that do not need to be flattened, the corresponding metal blocks 3 can be removed. This makes the present invention flexible and versatile in use and more applicable.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
