Description

Technical Field

[0001] This invention relates to the technical field of photovoltaic modules, and more particularly to a photovoltaic solar panel cutting device for building construction. Background Technology

[0002] Solar photovoltaic panels are structures composed of multiple layers of materials, including low-iron glass, solar cells, film, back glass, and special metal wires. During the production and processing of photovoltaic panels, the photovoltaic panel materials need to be cut and processed.

[0003] Different materials have different levels of hardness, and many of the materials used in solar panels contain monocrystalline or polycrystalline silicon, which has a high hardness.

[0004] However, in existing technologies, when cutting building solar photovoltaic panels in transport production lines, most are cut single-piece. This is because the panels are large and difficult to lift completely by hand. Also, due to the varying thicknesses of solar photovoltaic panels, stacking them requires high-cost, sensor-driven lifting equipment, which necessitates repeated system modifications. Therefore, single-piece cutting is often chosen to speed up the conveyor line and reduce costs. However, this method causes significant damage to the equipment, requiring frequent blade replacements and loosening of connecting nuts and other positioning structures in the conveyor, leading to cutting problems and affecting the process. Many people also use manual stacking, which requires repeated adjustments. Furthermore, the large area and weight of solar photovoltaic panels significantly impact production and can easily cause minor stacking deviations. In small-scale industries, manual stacking is often the only viable option.

[0005] To address this, a photovoltaic solar panel cutting device for building construction is proposed, which enables automated stacking during the cutting and production of photovoltaic solar panels for building construction. Summary of the Invention

[0006] The purpose of this invention is to provide a photovoltaic solar panel cutting device for building construction, which solves the stacking problem during the cutting and production of photovoltaic solar panels for building construction.

[0007] The technical solution of the present invention is as follows: a conveyor, further comprising a positioner and a cutter disposed outside the conveyor, a support plate 4 fixedly connected to one end of the conveyor, a lifting frame disposed at the other end of the positioner, a guide plate snapped onto one side of the support plate, a linkage assembly slidably connected inside the guide plate, a synchronous pull-down component connected between the guide plate and the linkage assembly, a check valve transmission component disposed on one side of the lifting frame, a bar connecting the linkage assembly and the check valve transmission component, and a support rod connecting the conveyor and the lifting frame. One end of the support rod is rotatably connected to the conveyor, and the other end of the support rod is slidably connected inside the lifting frame. The conveyor includes a support frame and a conveyor belt disposed on one side of the support frame. One side of the linkage assembly is located inside the support plate. The linkage assembly includes two positions: an initial position and a set position. When the linkage assembly is compressed and moves upward from the initial position, it drives the bar. The bar drives one end of the lifting frame to rotate upward through the check valve transmission component. When the linkage assembly moves upward to the set position, it moves downward through the synchronous pull-down component. When the linkage assembly is no longer compressed, it moves back to the initial position through the guide plate.

[0008] Furthermore, the guide plate has a guide groove and a straight groove inside. The linkage component includes a pressure block slidably connected inside the support plate, a return member slidably connected at one end inside the straight groove, and a drive guide member slidably connected inside the guide groove. The other end of the return member is located inside the drive guide member. The top of the pressure block is an arc surface, which is located on the side near the cutter. The bar is located inside the drive guide member.

[0009] Furthermore, the synchronous pull-down component includes a limiting frame welded to the bottom end of the guide plate, and a pull-back component connected between the pressure block and the limiting frame, wherein the limiting frame is provided with a translation groove.

[0010] The pull-back component includes a round rod whose bottom end is slidably connected inside the translation groove, and a pull-down spring connected between the round rod and the pressure block, wherein the pressure block is slidably connected to the outside of the round rod.

[0011] Furthermore, the drive guide includes a protrusion and a strip welded to one side of the pressure block, and a round shaft welded to the protrusion. A round groove is formed on one side of the protrusion, and a strip groove is formed on the side of the strip near the bar. The length of the strip is greater than the length of the protrusion, and one end of the bar is located inside the strip groove.

[0012] Furthermore, the return member includes a straight rod with one end located inside the straight groove, and a push spring connected between the straight rod and the protrusion, the other end of the straight rod being slidably connected inside the circular groove.

[0013] Furthermore, the lifting frame includes a base frame, a perforated plate rotatably connected to the top of the base frame, and a guard strip welded to the top of the perforated plate. One end of the support rod is connected to the inside of the perforated plate. Two support rods and two guard strips are provided and are symmetrical about the central axis of the perforated plate.

[0014] Furthermore, a mounting shell is provided on one side of the base frame, and the anti-return transmission component is located inside the mounting shell. The anti-return transmission component includes a worm gear rotatably connected inside the mounting shell, a first gear welded to the outside of the worm gear, a second gear welded to one side of the hollow plate, and a rack tooth meshing with the worm gear. The rack tooth is slidably connected inside the mounting shell, and one end of the rack is welded to the top of the rack tooth.

[0015] Furthermore, the circular shaft is located inside the guide groove, which is divided into an arc segment, a vertical segment, and a translation segment. The top ends of the arc segment and the vertical segment are interconnected, and the translation segment is interconnected with the bottom ends of the arc segment and the vertical segment. The circular shaft is positioned when it reaches the intersection point of the top ends of the arc segment and the vertical segment.

[0016] Furthermore, a housing is provided on one side of the support plate, the housing is located outside the bar, and a straight plate is provided on the top of both the support frame and the support plate. When the pressure block is in the initial position, the conveyor belt, the straight plate and the guard bar are at the same height.

[0017] Furthermore, the widths of the translation groove, the guide groove, and the pressure block are equal, and when the pressure block is in the initial position, the distance between one side of the bar and the pressure block is equal to the width of the guide groove.

[0018] The beneficial effects of this invention are:

[0019] 1. By adjusting the height of the material according to the linkage component, the linkage component controls the anti-reverse transmission component through the bar, so that the lifting frame raises the height of the subsequently conveyed material. That is, the height of the next material is exactly higher than the top of the previous material, thereby realizing continuous material production and automated stacking without waiting for manual intervention or manually lifting photovoltaic panels. It automatically adapts to materials of different thicknesses, thereby improving production efficiency. By utilizing the automatic compression of the material, the linkage component is triggered to automatically lift the material, so that the next material can be placed in place. This achieves a highly efficient production process, making the position and alignment of each material more accurate, ensuring the consistency of product placement, reducing errors introduced by human operation, and improving the accuracy of material stacking and conveying efficiency.

[0020] 2. The pressure block can automatically adapt to materials of different heights, thereby controlling the perforated plate to rotate and fit according to the thickness of the material. It is suitable for materials of various specifications and thicknesses, thus improving the applicability and flexibility of the equipment. At the same time, no external electric control equipment is required. The position of the pressure block is controlled by the material extrusion pressure, and the pressure block is connected to the guide plate through a round shaft to achieve automatic convergence, which will not affect the material transportation. The pressure block is automatically reset again using the round shaft and guide plate. The next batch of processing and cutting can be carried out automatically without control, effectively improving performance.

[0021] 3. The second gear receives power from the first gear to form a check valve structure, thereby preventing the material from putting pressure on the pressure block when it moves to the top of the perforated plate. At the same time, the support rod supports the perforated plate to ensure sufficient support for the material, thereby ensuring effective lifting and conveying, ensuring accurate positioning of the material, and ensuring the continuity and stability of cutting.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Example 1, referring to Figure 1-9 This invention provides a photovoltaic solar panel cutting device for building construction, comprising a conveyor 1, a locator 2 and a cutter 3 disposed outside the conveyor 1, a support plate 4 fixedly connected to one end of the conveyor 1, a lifting frame 5 disposed at the other end of the locator 2, a guide plate 6 snapped onto one side of the support plate 4, a linkage assembly 7 slidably connected inside the guide plate 6, a synchronous pull-down member 8 connecting the guide plate 6 and the linkage assembly 7, a check valve 9 disposed on one side of the lifting frame 5, a bar 10 connecting the linkage assembly 7 and the check valve 9, and a support rod 11 connecting the conveyor 1 and the lifting frame 5. One end of the support rod 11 is rotatably connected to the conveyor 1, and the other end of the support rod 11 is slidably connected inside the lifting frame 5. The conveyor 1 includes the support frame 1. 01 and the conveyor belt 102 located on one side of the support frame 101 drive the material 14 to move forward. One side of the linkage component 7 is located inside the support plate 4. The linkage component 7 includes two positions: the initial position and the set position. When the linkage component 7 is squeezed and moves upward from the initial position, it drives the bar 10. The bar 10 drives one end of the lifting frame 5 to rotate upward through the check transmission component 9. When the linkage component 7 moves upward to the set position, it moves downward through the synchronous pull-down component 8. When the linkage component 7 loses the squeeze, it moves back to the initial position through the guide plate 6. Usually, the material 14 is conveyed to the lifting frame 5 through the conveying equipment. Since the length of the material 14 is greater than that of the lifting frame 5, the material 14 will only lose the drive of the previous conveying equipment after entering the conveyor belt 102.

[0035] Reference Figure 1-3 The guide plate 6 has a guide groove 61 and a straight groove 62 inside. The linkage assembly 7 includes a pressure block 71 slidably connected inside the support plate 4, a return member 72 slidably connected at one end inside the straight groove 62, and a drive guide member 73 slidably connected inside the guide groove 61. The other end of the return member 72 is located inside the drive guide member 73. The top of the pressure block 71 is an arc surface 711, which is located on the side close to the cutter 3. The bar 10 is located inside the drive guide member 73. A notch is opened at the junction of the support plate 4 and the support frame 101 for installing the pressure block 71.

[0036] Reference Figure 1-7 The synchronous pull-down component 8 includes a limiting frame 81 welded to the bottom of the guide plate 6, and a pull-back component 82 connected between the pressure block 71 and the limiting frame 81. The limiting frame 81 is provided with a translation groove 811.

[0037] The pull-back member 82 includes a round rod 821 whose bottom end is slidably connected inside the translation groove 811, and a pull-down spring 822 connected between the round rod 821 and the pressure block 71. The pressure block 71 is slidably connected to the outside of the round rod 821.

[0038] Specifically, the limiting frame 81 restricts the translation of the round rod 821, which in turn restricts the pressure block 71, so that the pressure block 71 can only continue to translate up, down, left, and right, thereby ensuring the stability of the movement of the pressure block 71. The pressure block 71 can only move up and down outside the round rod 821, while the round rod 821 can translate inside the translation groove 811, so that when the pressure block 71 translates, it will drive the round rod 821 to move together. The pull-down spring 822 also moves with the round rod 821. When the pressure block 71 moves upward from the initial position, it will stretch the round rod 821.

[0039] Reference Figure 2-5 The drive guide 73 includes a protrusion 731 and a strip 732 welded to one side of the pressure block 71, and a round shaft 733 welded to the protrusion 731. A round groove 7311 is provided on one side of the protrusion 731, and a strip groove 7321 is provided on the side of the strip 732 near the bar 10. The length of the strip 732 is greater than the length of the protrusion 731, so that when the pressure block 71 moves, it provides the pressure block 71 with a moving space and the compression space of the push spring 722. One end of the bar 10 is located inside the strip groove 7321, and the width of the end of the bar 10 is half of the strip groove 7321. When the linkage assembly 7 is in the initial position, the position of the end of the bar 10 is located on the side away from the pressure block 71.

[0040] Reference Figure 2-6The return member 72 includes a straight rod 721 with one end located inside the straight groove 62, and a push spring 722 connected between the straight rod 721 and the protrusion 731. The other end of the straight rod 721 is slidably connected inside the circular groove 7311.

[0041] Specifically, the straight rod 721 can extend and retract inside the circular groove 7311, while the push spring 722, located between the straight rod 721 and the protrusion 731, is compressed when the circular shaft 733 moves to the position of the vertical section 612, thereby generating a rebound force on the pressure block 71. When the material 14 has not been conveyed away, the material 14 will continue to squeeze the pressure block 71, making it impossible for the push spring 722 to release its elastic force. After the material 14 moves, the pressure block 71 can re-enter the interior of the support plate 4 through the push spring 722 without obstruction.

[0042] Reference Figure 2-6 The lifting frame 5 includes a base frame 51, a perforated plate 52 rotatably connected to the top of the base frame 51, and a guard strip 53 welded to the top of the perforated plate 52. One end of the support rod 11 is connected to the inside of the perforated plate 52. There are two support rods 11 and two guard strips 53, which are symmetrical about the central axis of the perforated plate 52.

[0043] Specifically, the base frame 51 is a support structure for the bottom of one side of the perforated plate 52, which is placed on the ground. The other end of the perforated plate 52 is supported by a strut 11. This is achieved by setting grooves on both sides of the perforated plate 52, with one end of the strut 11 sliding in the groove. When the perforated plate 52 rotates, the strut 11 moves within the groove of the perforated plate 52 to ensure that the perforated plate 52 does not become suspended, thereby achieving stable material conveying 14.

[0044] Reference Figure 2-8 A mounting shell 511 is provided on one side of the base frame 51. The anti-return transmission component 9 is located inside the mounting shell 511. The anti-return transmission component 9 includes a worm 91 rotatably connected inside the mounting shell 511, a first gear 92 welded to the outside of the worm 91, a second gear 93 welded to one side of the hollow plate 52, and a rack 94 meshing with the worm 91. The rack 94 is slidably connected inside the mounting shell 511, and one end of the rack 10 is welded to the top of the rack 94.

[0045] The worm 91 meshes with the rack 94, and the second gear 93 meshes with the first gear 92.

[0046] Specifically, the up-and-down movement of the rack 94 drives the worm 91, which in turn drives the first gear 92. The second gear 93 receives the power from the first gear 92 in the final stage. During the subsequent conveying, the material 14 will exert pressure on the guard strip 53 as it passes over the top of the perforated plate 52. Since the second gear 93 and the first gear 92 are unidirectional, the perforated plate 52 will not rotate. At the same time, the pressure is applied between the first gear 92 and the second gear 93, preventing the pressure from being transmitted to the pressure block 71 through the rack 94 and the bar 10, which would cause the pressure block 71 to exert greater pressure on the material 14. Even if the material 14 is hard, this further prevents damage to the device.

[0047] In addition, the mounting shell 511 is provided with a through slot to ensure that the bar 10 passes through the through slot and connects with the bar tooth 94. At the same time, the transmission ratio of the second gear 93, the worm gear 91 and the bar tooth 94 corresponds to the thickness of the material 14. That is, the amount by which the bar tooth 94 moves upward is transmitted through the second gear 93, which will cause one end of the hollow plate 52 to rotate and rise to the same height.

[0048] Reference Figure 3-9 The circular shaft 733 is located inside the guide groove 61, which is divided into an arc-shaped section 611, a vertical section 612, and a translational section 613. The top ends of the arc-shaped section 611 and the vertical section 612 are interconnected, and the translational section 613 is interconnected with the bottom ends of the arc-shaped section 611 and the vertical section 612. The circular shaft 733 is positioned when it reaches the intersection point of the top ends of the arc-shaped section 611 and the vertical section 612.

[0049] Specifically, when the pressure block 71 is initially positioned at the bottom of the arc segment 611, it moves upward under pressure, causing the circular shaft 733 to move upward as well. The pressure block 71 moves along the path of the guide groove 61, which in turn causes it to move along the path of the guide groove 61. The top of the arc segment 611 tilts towards the vertical segment 612, and as the circular shaft 733 moves towards the vertical segment 612, it also causes the pressure block 71 to move. This ensures that after the last material 14 is stacked, the pressure block 71 will automatically move out of the support plate 4 without affecting the movement of the material 14. After the circular shaft 733 enters the vertical segment 612, the pressure block 71 is no longer obstructed by the material 14 below, and the pull-down spring 822 rebounds, causing the pressure block 71 to move downward. The circular shaft 733 then enters the translation segment 613. However, the side of the pressure block 71 is also obstructed by the material 14 and will not enter the support plate 4.

[0050] Reference Figure 1-9A housing 12 is provided on one side of the support plate 4. The housing 12 is located outside the bar 10 and is used for protection. A straight plate 13 is provided on the top of both the support frame 101 and the support plate 4. When the pressure block 71 is in the initial position, the height of the conveyor belt 102, the straight plate 13 and the guard bar 53 are equal. The straight plate 13 restricts multiple materials 14. It can be replaced when dealing with materials 14 of different thicknesses. At the same time, the corresponding guide plate 6 needs to be replaced to deal with materials 14 of different thicknesses.

[0051] Reference Figure 1-9 The translation groove 811, guide groove 61, and pressure block 71 have equal widths, which allows the round rod 821 to move by that width inside the translation groove 811. At this time, the pressure block 71 will also move by that distance, so that the pressure block 71 can completely move out of the support plate 4 to avoid disturbing the conveying of the material 14. When the pressure block 71 is in the initial position, the distance between one side of the bar 10 and the pressure block 71 is equal to the width of the guide groove 61. Therefore, when the round shaft 733 is inside the vertical section 612, the bar 10 and the pressure block 71 are in contact, which makes the cutter 3 not affect other components when cutting.

[0052] The working principle of this invention is as follows: Material 14 is transported to the lifting frame 5 via the conveyor line, and as material 14 is driven by the conveyor line to reach the top of the support frame 101, material 14 continues to move forward due to the drive of the conveyor belt 102. The conveyor belt 102 will squeeze the arc surface 711 of the pressure block 71, causing the pressure block 71 to move upward. The pressure block 71 will drive the protrusion 731, the strip 732 and the round shaft 733 to move synchronously. Since the round shaft 733 is located inside the guide groove 61, the upward movement of the pressure block 71 will be restricted by the guide plate 6, and thus the pressure block 71 will move along the path of the guide groove 61. At the same time, the pressure block 71 will stretch the pull-down spring 822, and the round shaft 733 will drive the straight rod 721 to move upward inside the straight groove 62. The flat spring 722 will move upward with the pull-down spring 822. The straight rod 721 and the round shaft 733 move upward, and the upward movement of the strip block 732 will drive the strip rod 10 to move upward. At this time, the upward movement of the strip rod 10 will drive the rack tooth 94 to move upward. The rack tooth 94 drives the worm gear 91 and the first gear 92 to rotate synchronously, so that the first gear 92 drives the second gear 93 to rotate. At this time, the second gear 93 drives the hollow plate 52 to rotate around the second gear 93 as the center, so that the side of the hollow plate 52 near the support frame 101 tilts upward. The support rod 11 will move inside the hollow plate 52. The support rod 11 supports the hollow plate 52, and then the material 14 is conveyed. After the material 14 reaches the hollow plate 52, it will tilt upward, and then the next material 14 will be conveyed at a height higher than the one material 14 that has moved upward. Each material 14 will squeeze the pressure block 71, thus repeating the above steps.

[0053] As multiple materials 14 gradually accumulate, the pressure block 71, due to the circular shaft 733 being located inside the guide groove 61, moves along the arc segment 611 as the circular shaft 733 moves, causing the pressure block 71 to move towards the vertical segment 612. The pressure block 71 drives the protrusion 731, the strip 732, and the circular shaft 733 to move synchronously. The straight rod 721 and the push spring 722 only move up and down with the pressure block 71. As the protrusion 731 moves, it compresses the push spring 722, causing the straight rod 721 to enter the interior of the circular groove 7311. Since bar 10 does not move, but bar block 732 moves, the position of bar 10 inside groove 7321 changes, and bar 10 then comes into contact with pressure block 71. When pressure block 71 translates, it drives round bar 821 to move inside translation groove 811. Round bar 821 and pull-down spring 822 translate with pressure block 71. When round shaft 733 reaches the junction of arc segment 611 and vertical segment 612, round shaft 733 enters the interior of vertical segment 612. Since pull-down spring 822 is stretched by pressure block 71, pull-down spring 822 rebounds and moves downward. The pressure block 71 moves downward, and the connected components move downward synchronously. The round shaft 733 reaches the translation section 613. At this time, the push spring 722 is compressed and pushes the protrusion 731. However, the pressure block 71 is blocked by multiple materials 14 and cannot move back. When the pressure block 71 moves downward, it drives the rack 94 to move downward through the bar 10. The rack 94 drives the worm gear 91 and the first gear 92, so that the second gear 93 is driven to rotate by the first gear 92. The hollow plate 52 rotates accordingly and becomes collinear with the support frame 101. At this time, the positioner 2 can be used to move the pressure block 71 downward. Multiple materials 14 are fixed, and then cut by the cutter 3. The cut materials 14 are then conveyed to the next process. Since the materials 14 in this batch are conveyed synchronously, they will continue to block the pressure block 71 until the materials 14 in this batch are cut. After the materials 14 are conveyed, the pressure block 71 is no longer blocked, and the push spring 722 rebounds, causing the protrusion 731 to be pushed. The round shaft 733 moves from the inside of the translation section 613 to the inside of the arc section 611, and the pressure block 71 also moves back to the inside of the support plate 4, so that the next batch of processing and cutting can be carried out.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
