Description

Technical Field

[0001] This invention relates to the field of photovoltaic production, and in particular to a photovoltaic thermal PVT board cutting device. Background Technology

[0002] A photovoltaic-thermal (PVT) panel is a composite energy device that combines photovoltaic power generation with solar thermal utilization. Based on traditional photovoltaic panels (which utilize the photovoltaic effect of semiconductor materials to convert solar energy into electrical energy), it integrates a solar thermal collection system, enabling simultaneous photoelectric and solar thermal conversion of solar energy.

[0003] In the production and processing of photovoltaic and solar thermal PVT (PVT) panels, glass plates, solar cells, insulating boards, heat exchange substrates, flame-retardant insulation layers, and frame back panels need to be prepared according to design requirements. The insulating boards, heat exchange substrates, flame-retardant insulation layers, and frame back panels need to be precisely cut before assembly to meet the size requirements of different installation scenarios. After the cutting process is completed, they are combined and installed with glass plates and solar cells to form photovoltaic and solar thermal PVT panels.

[0004] However, traditional cutting equipment has a relatively simple function and generally lacks automated pushing function. Manual feeding is labor-intensive and inefficient. For heavy or long boards, manual handling is not only physically demanding, but also makes it difficult to ensure the continuity of board placement.

Without changing the conveying components, it can easily adapt to the cutting needs of PVT boards of different widths. When the sliding seat moves, the hinged rod drives the slider and driven wheel to move synchronously, automatically applying tension to the belt to ensure stable belt drive.

[0030] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] like Figure 1 - Figure 3 As shown, one embodiment of the present invention provides a photovoltaic thermal PVT board cutting device, including a processing table 1. A fixed frame 2 is fixedly connected to the surface of the processing table 1. Two sets of electric telescopic rods 7 are fixedly connected to the top of the fixed frame 2. An upper cutter 3 is fixedly connected to the telescopic ends of the two sets of electric telescopic rods 7. Guide sleeves 4 are fixedly connected to both sides of the upper cutter 3. The fixed frame 2 consists of a set of support boxes and two side support rods. By setting guide sleeves 4 on both sides of the upper cutter 3, the upward movement of the upper cutter 3 can be guided. The guide sleeves 4 can only move up and down at the support rods on both sides of the fixed frame 2. A lower cutter seat 8 is fixedly connected to the surface of the processing table 1. A clamping module 5 is set on the outer side of the upper cutter 3. The clamping module 5 is a prior art technology. By lowering the upper cutter 3, the clamping module 5 can be driven to clamp the rear end of the cut section of the board, avoiding deviation during the cutting process. A conveying mechanism 6 is set on the front surface of the processing table 1.

[0032] like Figure 4 and Figure 5 and Figure 7As shown, the conveying mechanism 6 includes a placement frame 601, which, together with the push plate 618, forms an L-shape, allowing the plates to be cut to be stacked layer by layer on the inner surface of the placement frame 601. The surface of the placement frame 601 is marked with graduations, allowing the width of the plates to be visually observed by moving the push plate 618. The placement frame 601 is fixedly connected to the front surface of the processing table 1. A rotating block 602 is rotatably connected to the side wall at the bottom of the placement frame 601. A sliding groove is formed at the bottom of the placement frame 601, and the rotating block 602 is rotatably connected to the inner wall of the sliding groove. A threaded rod 603 is fixedly connected to the rotation center axis of the rotating block 602. A sliding seat 604 is threadedly connected to the surface of the threaded rod 603, and an internal threaded groove is formed at the top of the sliding seat 604. The rotating block 602 can follow the rotation of the push plate 602. Synchronous rotation allows the sliding seat 604 to move threadedly on the surface of the threaded rod 603, while simultaneously changing the stroke of pulleys b609 and a607 to adjust the conveying according to different widths of plates. The top of the sliding seat 604 is slidably connected to the inner wall of the bottom groove of the placement frame 601, and the top of the outer wall of the sliding seat 604 is fixedly connected to a push plate 618. When the sliding seat 604 moves and is adjusted, it will drive the push plate 618 to move synchronously on the surface of the placement frame 601. The left side of the sliding seat 604 is rotatably connected to pulley b609, which is connected to pulley a607 via belt 608. When pulley a607 is driven by the output of motor 606, pulley a607 will drive pulley b609 to move synchronously with it via belt 608.

[0033] like Figure 4 and Figure 5As shown, a fixed base 605 is rotatably connected to the rear end of pulley a607. The fixed base 605 is fixedly connected to the bottom end of the outer wall of the placement frame 601. A motor 606 is fixedly connected to the outer side wall of the fixed base 605. By fixing the fixed base 605 to the bottom end of the placement frame 601, the motor 606 and pulley a607 can be supported. The output shaft of the motor 606 is fixedly connected to the rotation center axis of pulley a607. A contact block 614 is fixedly connected to the surface of the belt 608. The belt 608 is connected to the pulley. When the surfaces of a607 and pulley b609 are driven by transmission, the contact block 614 will move synchronously on their surfaces. A guide groove is provided at the center of the placement frame 601, and a guide groove of the same width is provided below the push plate 618. The outer sidewall of the contact block 614 contacts the inner wall of the guide groove of the placement frame 601 and the push plate 618. The contact between the two allows the contact block 614 to move synchronously with the belt 608 when it rotates. Only one set of contact blocks 614 is provided. This allows the bottommost photovoltaic (PVT) panels stacked on the surface of the placement rack 601 to be brought into contact with and transported to the upper cutter 3 for cutting. A guide frame 610 is fixedly connected to the center of the bottom of the placement rack 601. A slider 611 is slidably connected to the inner side wall of the guide frame 610. A hinge rod 613 is hinged to the outer side wall of the slider 611. The end of the hinge rod 613 away from the slider 611 is hinged to the side wall of the bottom of the sliding seat 604. When the sliding seat 604 moves, it is pushed by the hinge rod 613. The movable slider 611 moves up and down on the inner wall of the guide frame 610, thereby driving the driven wheel 612 to move synchronously to contact the inner side of the belt 608. As the pulley b609 moves, the transmission of the belt 608 becomes loose, and the driven wheel 612 moves accordingly, thus applying tension to the belt 608, so that the belt 608 can transmit power stably. The driven wheel 612 is rotatably connected to the outer side wall of the slider 611, and the outer arc surface of the driven wheel 612 contacts the inner surface of the belt 608.

[0034] like Figure 5 - Figure 6As shown, an extension block 616 is slidably connected to the inner sidewall of the contact block 614 via a limiting component 615. A groove is provided at the center of the contact block 614, and the outer wall of the extension block 616 contacts the inner wall of the groove of the contact block 614. By setting the extension block 616 to slide on the inner wall of the contact block 614, the length of the extension block 616 can be adjusted, thereby adjusting the contact and pushing according to photovoltaic thermal PVT panels of different thicknesses. A rotating wheel 617 is rotatably connected to the inner sidewall of the front end of the extension block 616. By setting the rotating wheel 617, when the contact block 614 and the extension block 616 are conveying the plates piled on the surface of the placement rack 601, the rotation of the rotating wheel 617 and its contact with the upper end of the conveyed plates can reduce friction. The limiting component 615 includes a wedge 615. 2. The wedge 6152 is elastically connected to the inner sidewall of the extension block 616 via a return spring 6151. One end of the return spring 6151 is fixedly connected to the outer sidewall of the wedge 6152, and the other end is fixedly connected to the inner sidewall of the extension block 616. The function of the return spring 6151 is to automatically reset the position of the wedge 6152 after it has been pressed and moved. The wedge 6152 is slidably connected to the inner sidewall of the extension block 616. A positioning groove is provided on the outer sidewall of the contact block 614. The outer wall of the wedge 6152 contacts the inner wall of the positioning groove of the contact block 614. The contact between the two allows the extension block 616 to be moved inside the contact block 614 and then fixed in multiple positions after adjustment according to the different thicknesses of the photovoltaic thermal PVT board.

[0035] Working principle: First, the operator stacks the plates to be cut layer by layer on the inner surface of the placement rack 601 of the conveying mechanism 6. The L-shaped structure formed by the placement rack 601 and the push plate 618 achieves stable stacking of the plates. According to the width of the plates to be cut, the operator rotates the rotating block 602, which drives the threaded rod 603 to rotate synchronously. Since the sliding seat 604 is threadedly connected to the threaded rod 603, and the top of the sliding seat 604 is slidably connected to the inner wall of the groove at the bottom of the placement rack 601, the sliding seat 604 will move on the surface of the threaded rod 603. The screw thread moves, thereby changing the distance between pulley b609 and pulley a607, and also driving the push plate 618 to move synchronously to adapt to the conveying needs of plates of different widths. During the movement of the sliding seat 604, the slider 611 is pushed up and down on the inner wall of the guide frame 610 through the hinge rod 613, so that the driven wheel 612 moves along with it and contacts the inner side of the belt 608, thereby applying tension to the belt 608 and ensuring stable transmission of the belt 608 between pulley a607 and pulley b609.

[0036] Meanwhile, the overall length is changed by adjusting the position of the extension block 616 inside the contact block 614 according to the thickness of the plate. During adjustment, the wedge block 6152 is pressed to compress the return spring 6151 and disengage from the positioning groove of the contact block 614. After moving the extension block 616 to the appropriate position, the wedge block 6152 is released. Under the action of the return spring 6151, the wedge block 6152 is inserted into the corresponding positioning groove of the contact block 614, thereby fixing the position of the extension block 616.

[0037] When the motor 606 is started, the output end of the motor 606 drives the pulley a607 to rotate. The pulley a607 drives the pulley b609 to rotate synchronously through the belt 608. The contact block 614 on the surface of the belt 608 moves accordingly. When the contact block 614 and the extension block 616 contact the bottommost plate stacked on the placement rack 601, the friction with the plate is reduced by the rotation of the wheel 617 under the transmission of the belt 608, and the plate is pushed to the surface of the processing table 1, completing the plate conveying. At this time, the plate stacked on the upper side will fall to the bottom of the inner side of the placement rack 601 after the contact block 614 rotates once.
