Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic glass preparation, and in particular to a device and method for preparing surface-textured photovoltaic glass. Background Art

[0002] Surface textured glass, also known as velvet glass, is a glass surface that is formed with a uniform velvet structure through a specific process. During the preparation process, an ultrafast laser is used to emit a pulsed laser beam, and the laser beam is focused on the glass surface through a focusing lens, thereby processing the glass surface and obtaining a microstructure. The microstructure is then etched with a chemical solution to complete the overall preparation and molding of the photovoltaic glass.

[0003] After searching, the patent number CN113695747A discloses a device and method for preparing surface textured photovoltaic glass. The device installs the photovoltaic glass at a specified position of a plastic box, emits a pulsed laser beam through an ultrafast laser, and then focuses the laser beam on the surface of the photovoltaic glass through a focusing lens, thereby realizing microstructural processing of the photovoltaic glass; at the same time, the present invention also protects the preparation method of surface textured photovoltaic glass. While performing microstructural processing on the photovoltaic glass, a nanostructure is induced on the wall of the microstructure, and slag is generated at the edge of the microstructure and the surface of the photovoltaic glass to form nanopores, forming a roughened layer of the glass. By injecting a chemical solution into the plastic box, the roughened layer of the photovoltaic glass is etched, thereby improving the light transmittance of the photovoltaic glass.

[0004] However, during operation, the above-mentioned device needs to perform laser irradiation and chemical solution etching in sequence when processing a single piece of glass, resulting in a long overall operation time. When a large amount of glass is prepared, the etching work cannot be completed while laser irradiation is being performed, thereby reducing the preparation efficiency of photovoltaic glass. Summary of the invention

In the liquid solution tank 7, the upper end of the infusion tube 9 passes through the base frame 2 and is connected to a nozzle 11 through a connecting pipe 10. The connecting pipe 10 is a telescopic bellows. A rotating rod 12 is rotatably passed through the rear side of the processing table 1. A placement plate 13 is fixedly provided at the front end of the rotating rod 12. Cavities are opened at both ends of the placement plate 13. Two symmetrically arranged splints 14 are provided inside the two cavities through an adjustable clamping mechanism. The adjustable clamping mechanism includes a bidirectional screw rod 15. The bidirectional screw rod 15 is rotatably arranged in the cavity. The splint 14 is threadedly sleeved on the outside of the rod wall of the bidirectional screw rod 15. A rotating hole cooperating with the rotation of the bidirectional screw rod 15 is opened on the side of the placement plate 13. Sliding holes are opened at one end away from the two cavities, and multiple splints 14 are slidably arranged in the sliding holes.

[0020] Before processing the photovoltaic glass, the chemical solution is poured into the chemical solution tank 7 in advance, and the glass is placed on the surface of the placement plate 13, and then the bidirectional screw rod 15 is rotated so that the bidirectional screw rod 15 drives the two clamping plates 14 of its rod wall to approach each other and stably clamp the glass. Then the three-axis moving frame 3 is started and drives the ultrafast laser emitter 4 to move. At this time, the ultrafast laser emitter 4 cooperates with the lens 6 to avoid laser irradiation on the glass and completes the preliminary processing. After the laser processing time is over, the placement plate 13 is driven to rotate by the rotating rod 12, so that the upper glass is flipped to the bottom, and then the liquid pump 8 is started to suck the chemical solution inside the chemical solution tank 7 through the infusion tube 9, and the solution is sprayed to the glass through the connecting tube 10 and the nozzle 11 to chemically etch the glass. Before the chemical solution is sucked, the untreated glass can be placed on the upper surface of the placement plate 13 and clamped, so that when the lower glass is being etched, the upper glass is synchronously laser processed, thereby improving the preparation efficiency when a large amount of glass is prepared.

[0021] In order to fix the positions of the placement plate 13 and the glass after the glass is laser processed and turned over, as shown in FIG. Figure 1-2 As shown, a flip positioning mechanism for limiting the position of the placement plate 13 is provided between the rear end of the rotating rod 12 and the back side of the processing table 1, and the flip positioning mechanism includes a rotating plate 16, which is fixedly sleeved on the outer side of the rear end of the rotating rod 12, and two symmetrically arranged partitions 17 are fixedly provided on the outer wall of the rotating plate 16, and two symmetrically arranged fixed plates 18 are fixedly provided on the back side of the processing table 1, and a fixing rod 19 is fixedly provided between the two fixing plates 18, and a clamping plate 20 is rotatably sleeved on the rod wall of the fixing rod 19, and the clamping plate 20 is clamped between the two partitions 17, and a torsion spring 21 is sleeved on the rod wall of the fixing rod 19, and the two ends of the torsion spring 21 are respectively fixedly connected to the fixing rod 19 and the clamping plate 20.

[0022] When the glass is laser processed, the card plate 20 is inserted into the gap between the two partitions 17. At this time, the position of the rotating rod 12 is fixed. When the glass needs to be flipped, the card plate 20 can be turned out from between the two partitions 17. At this time, the card plate 20 rotates around the fixed rod 19 and twists the torsion spring 21. When the card plate 20 is separated from the partition 17, the rotating rod 12 can be rotated so that the rotating rod 12 drives the placement plate 13 to flip and change position. Then the card plate 20 is released. Under the torsion recovery of the torsion spring 21, the card plate 20 is inserted into the gap between the two partitions 17 again, thereby completing the position determination of the rotating rod 12, the placement plate 13 and the glass, ensuring the stable progress of chemical etching and laser processing.

[0023] In order to drive the bidirectional screw rod 15 to rotate and avoid the bidirectional screw rod 15 from being accidentally pushed during processing, Figure 1 and Figure 3As shown, a telescopic rod 22 is fixedly provided on the outer wall of the placement plate 13, a connecting block 23 is fixedly sleeved on the rod wall of the telescopic rod 22, a vertical plate 24 is rotatably sleeved on the outer wall of the connecting block 23, a positioning rod 25 is rotatably penetrated inside the vertical plate 24, the end of the positioning rod 25 away from the crank 26 and the longitudinal section of the positioning groove are both rectangular, a crank 26 is fixedly provided on the end of the positioning rod 25, a positioning groove for mating with the positioning rod 25 is opened on the end of the bidirectional screw rod 15, a spring 27 is sleeved on the rod wall of the telescopic rod 22, and the two ends of the spring 27 are respectively fixedly connected to the telescopic rod 22 and the placement plate 13.

[0024] When it is necessary to drive the bidirectional screw rod 15 to rotate and complete the clamping of the glass by the clamping plate 14, the vertical plate 24 is pulled horizontally, so that the vertical plate 24 stretches the telescopic rod 22 and the spring 27. At this time, the vertical plate 24 drives the positioning rod 25 to rotate to the side of the end of the bidirectional screw rod 15 at the corresponding position, and then the vertical plate 24 is released. Under the elastic recovery of the spring 27, the positioning rod 25 follows the vertical plate 24 and is inserted into the positioning groove at the end of the bidirectional screw rod 15. Then, the crank 26 is turned, so that the crank 26 drives the positioning rod 25 to rotate and drives the bidirectional screw rod 15 to rotate. During the processing, the positioning rod 25 is not connected to the bidirectional screw rod 15 at any position, so as to store the bidirectional screw rod 15, and try to avoid the bidirectional screw rod 15 being accidentally pushed during the glass preparation process and affecting the processing position of the glass, thereby improving the stability of the glass preparation process.
