Description

Technical Field

[0001] The present invention relates to the field of photovoltaic panel production, and in particular to a polishing device for photovoltaic solar panel production. Background Art

[0002] Solar photovoltaic panels primarily consist of solar cells, packaging materials, frames, and junction boxes. The packaging materials include glass, film, and a backsheet. Chinese invention patent publication number CN218461703U discloses a tempered glass polishing device for photovoltaic modules. The device uses two clamping blocks to secure the glass, and then a grinding wheel rotates to polish the glass.

[0003] The applicant believes that the current production process of photovoltaic glass makes the glass surface smooth enough and does not require further polishing. On the contrary, the surface of photovoltaic glass needs to be coated with an anti-reflective coating. Polishing will damage the coating or cause the glass surface to be uneven, reducing the coating effect. Therefore, there is no need to polish the glass surface. However, the edges of the glass, especially after cutting, are relatively sharp, which can easily scratch the operator or damage other materials (such as backboards, EVA films), so the edges of the glass need to be ground. Edge grinding can remove micro-cracks, burrs and sharp angles caused by cutting, prevent edge collapse or even breakage during later transportation or installation, and improve the overall impact resistance of the glass. At the same time, the glass edges are flat, which can better bond with the sealant and reduce sealing dead angles.

[0004] Based on this, the applicant proposed a grinding device for producing photovoltaic solar panels to grind the edges of photovoltaic glass. Summary of the Invention

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0037] Please combine Figure 1-Figure 2 The photovoltaic solar panel polishing device of this embodiment includes a base 1 and a workbench 3. A slideway 11 is provided on the base 1. A drive shaft 12 and a guide shaft 13 are mounted within the slideway 11. The drive shaft 12 is a threaded shaft with a servo motor connected at one end. The lower end of the workbench 3 slides within the slideway 11, with the drive shaft 12 and guide shaft 13 extending through the workbench 3. When the motor drives the drive shaft 12 to rotate, the workbench 3 moves along the slideway 11.

[0038] Furthermore, a fixing platform 2 is fixedly connected to the base 1. The photovoltaic glass panel to be polished is placed on the fixing platform 2. The fixing platform 2 is also equipped with a pressure plate 21 and a hydraulic telescopic shaft (not shown) that controls the lifting and lowering movement of the pressure plate 21. When the pressure plate 21 is moved downward, the photovoltaic glass panel is fixed to the fixing platform 2.

[0039] Please combine Figure 3-Figure 5 The workbench 3 is fixedly connected to a polishing box 4. Two positioning shafts 52 are fixedly connected to the polishing box 4, and a curved connecting rod 53 is rotatably mounted on the positioning shafts 52. Furthermore, two movable frames 5 are disposed within the polishing box 4. The middle portion of the curved connecting rod 53 is rotatably connected to the positioning shaft 52, while the ends are movably connected to the two movable frames 5, respectively, located above and below the rotating shaft.

[0040] by Figure 4 Taking the direction shown as an example, if the movable frame 5 located above the curved connecting rod 53 is pushed in direction A, the curved connecting rod 53 will rotate clockwise around the positioning axis 52, and the curved connecting rod 53 will then drive the movable frame 5 below to move in direction B. Because the curved connecting rod 53 can only rotate around the positioning axis 52, the movement direction of the upper and lower movable frames 5 is a curve.

[0041] Also refer to Figure 5 In addition, a limiting mechanism 6 is provided inside the inner seat of the fixing frame. Specifically, the limiting mechanism 6 includes a fixing block 61, two L-shaped moving blocks 63 and two spherical connecting rods 65.

[0042] First, the fixed block 61 is fixedly connected to the interior of the polishing box 4. The upper and lower surfaces of the fixed block 61 are provided with a dovetail-shaped No. 1 limit groove 62. One end of the L-shaped limit block is slidably installed in the No. 1 limit groove 62, and the L-shaped limit block can move horizontally along the No. 1 limit groove 62. Correspondingly, a vertical No. 2 limit groove 64 is provided on one side of the L-shaped movable block 63. The above-mentioned spherical connecting rod 65 is composed of a spherical structure and a short rod, wherein the spherical structure is slidably installed in the No. 2 limit groove 64, and the spherical connecting rod 65 can move up and down in the No. 2 limit groove 64. The other end of the spherical connecting rod 65 is fixedly connected to the above-mentioned movable frame 5.

[0043] In summary, if the L-shaped moving block 63 is controlled to move along the No. 1 limiting groove 62 , the two movable frames 5 can also be driven to move along the A and B directions.

[0044] Replay Figure 4 In order to polish the edge of the glass, a fiber polishing cloth 9 and two connecting plates 7 are provided. The two ends of the fiber polishing cloth 9 are connected to the two connecting plates 7 respectively.

[0045] If the fiber polishing cloth 9 is moved to the edge of the photovoltaic glass plate, the edge of the photovoltaic glass can be polished as the connecting plates at the upper and lower ends of the fiber polishing cloth 9 extend and retract to reset.

[0046] In actual use, the physical wear, contamination, and clogging of the fiber polishing cloth 9 over time can directly lead to reduced polishing quality and efficiency, and even damage to the workpiece. Therefore, regular inspection and replacement are necessary. To facilitate replacement and adjustment of the fiber polishing cloth 9, a hole is formed at the end of the movable frame 5 away from the stopper mechanism 6, into which one end of the connecting plate 7 is inserted.

[0047] In order to fix the connecting plate 7, a spring button 71 is installed on the connecting plate 7 (that is, a spring is provided under the button, and the spring pushes up the button, which is the existing structure). An adjustment hole 51 is provided on the movable frame 5 (in this embodiment, the number of the adjustment holes 51 is three). When one end of the connecting plate 7 is inserted into the movable frame 5, the spring button 71 will extend out of the adjustment hole 51. When the spring button 71 is pressed, the connecting plate 7 can be pulled out of the movable frame 5. Because there are three adjustment holes 51, when the spring button 71 is controlled to use different adjustment holes 51, the distance between the connecting plate 7 and the fiber polishing cloth 9 and the fixed table 2 (photovoltaic glass panel) can be controlled, which is suitable for photovoltaic glass panels of different sizes.

[0048] Reference Figure 6 and Figure 7 In order to facilitate the control of the fiber polishing cloth 9 to polish the glass edge, a connecting drive structure 8 is also provided. Specifically, the connecting drive structure 8 includes a rotating disk 81. First, a cavity is opened inside the workbench 3, and the rotating disk 81 is rotatably installed in the cavity of the workbench 3. A rotating column 82 is fixedly connected to the rotating disk 81 away from the center of the circle. In addition, the connecting drive structure 8 also includes a connecting sleeve 83 and a connecting rod 84. The connecting sleeve 83 is oblong and is mounted on the outside of the rotating column 82. Two connecting rods 84 are provided, symmetrically connected on both sides of the connecting sleeve 83.

[0049] In addition, a square hole is provided on the workbench 3, and the connecting rod 84 is L-shaped, with its upper end extending out of the workbench 3 through the square hole, and then extending into the polishing box 4, and fixedly connected to the L-shaped moving block 63. The connecting rod 84 can reciprocate along the direction of the square hole.

[0050] The lower end of the rotating disk 81 is fixedly connected to a connecting shaft 85 , and the connecting shaft 85 is rotatably connected to the workbench 3 via a bearing. The lower end of the connecting shaft 85 extends out of the workbench 3 and is fixedly connected to a gear 86 .

[0051] In cooperation with the gear 86, a tooth plate 87 is further provided in this embodiment, and the gear 86 meshes with the tooth plate 87. The tooth plate 87 is fixedly connected to the base 1.

[0052] The implementation steps and principles of a photovoltaic solar panel production polishing device in the embodiment of the present application are as follows:

[0053] (1): First, place the photovoltaic glass to be polished on the workbench 3 and fix the photovoltaic glass panel by controlling the downward movement of the pressure plate 21. Then, by adjusting the position of the spring button 71, control the length of the connecting plate 7 extending from the movable frame 5 so that the fiber polishing cloth 9 fits the side of the glass.

[0054] (2): The motor can drive the drive shaft 12 to rotate back and forth, thereby driving the workbench 3 to move back and forth along the axial direction of the drive shaft 12, that is, the workbench 3 moves back and forth in the slideway 11;

[0055] As the worktable 3 reciprocates, gear 86 also moves. Since gear 86 meshes with toothed plate 87, which is fixed, gear 86 rotates simultaneously. Gear 86 drives rotating disk 81 via connecting shaft 85. Rotating disk 81 rotates, driving connecting rods 84 on either side to reciprocate left and right through the interaction of rotating post 82 and connecting sleeve 83.

[0056] (3): The connecting rod 84 will drive the L-shaped moving block 63 located below the curved connecting rod 53 to move back and forth. As described above, the two movable frames 5 located on the upper and lower sides of the curved connecting rod 53 move in opposite directions, and their movement trajectories are arc-shaped. Therefore, according to Figure 2 As shown, when the connecting rod 84 pushes the movable frame 5 located below the curved connecting rod 53 to the right, the movable frame 5 located above the curved connecting rod 53 will move to the left. During this process, the two connecting plates 7 will also move, and the two connecting plates 7 connected to the fiber polishing cloth 9 will alternately extend and retract to reset, thereby driving the fiber polishing cloth 9 to polish the side of the photovoltaic glass panel and remove burrs.

[0057] During the polishing process, the fiber polishing cloth 9 reciprocates, dissipating heat during the polishing process. This prevents heat concentration from damaging the photovoltaic glass panel, thus eliminating the need for water cooling. Furthermore, the fiber polishing cloth 9 can polish the right-angled edges of the photovoltaic glass into a curved transition, making the photovoltaic glass panel less prone to edge collapse and providing improved impact resistance.

[0058] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
