Description

Technical Field

[0001] This invention relates to the field of cutting device technology, and specifically to a photovoltaic panel frame cutting device. Background Technology

[0002] During the production process of photovoltaic panel frames, a circular saw cutting device is required to cut the photovoltaic panel frames to a fixed length or at an angle.

[0003] Chinese patent CN223028602U discloses a steel component cutting device, belonging to the technical field of cutting devices. It includes a base, with a placement platform fixedly connected to the top of the base's outer surface. A clamping and moving structure is provided on the top of the placement platform's outer surface, and a cutting protection structure is provided on one side of the placement platform. The clamping and moving structure includes a first rectangular frame, the bottom of which is fixedly connected to the top of the placement platform's outer surface. This prior art, by setting up the clamping and moving structure, can drive the U-shaped clamping frame to move under the action of a first screw and a first screw hole block, thereby driving the steel component inside the U-shaped clamping frame to move and be transported, eliminating the need for manual pushing. Under the action of a second screw and a second screw hole block, it can drive the clamping plate to move, thereby fixing both sides of the steel component, thus facilitating the fixing and cutting of the steel component.

[0004] However, when the circular saw blade is cutting the frame, the cutting interval is long under normal production rhythm, so liquid cooling is not used. But in order to improve the production efficiency of photovoltaic panel frames, the cutting interval may be reduced. At this time, the frequency of use of the circular saw blade increases, which may cause the circular saw blade to overheat, thereby affecting the service life of the circular saw blade. Summary of the Invention

[0007] Preferably, the cutting assembly includes a limiting component, a drive unit, a moving frame, and a circular saw unit; the limiting component is mounted on the worktable and is used to limit the border; the drive unit is mounted outside the worktable, and the moving frame is located on the output end of the drive unit; the circular saw unit is mounted on the moving frame and is used to cut the border.

[0008] Preferably, the circular saw unit includes a pressure sensor, a support plate, and an electric circular saw; the pressure sensor is mounted on the side of the moving frame; the support plate is mounted on the test end of the pressure sensor; and the electric circular saw is mounted on the support plate.

[0009] Preferably, the infusion assembly includes a cylinder, a telescopic tube, an infusion pump, an infusion pipe, and a spray unit; the cylinder is installed inside a movable frame, the two ends of the telescopic tube are respectively connected to the cylinder and the infusion pump, and the infusion pump is installed inside a workbench; the infusion pipe is connected to the cylinder; and the spray unit is rotatably connected to the infusion pipe.

[0010] Preferably, the bonding assembly includes an elastic element and an air blowing unit; the two ends of the elastic element are respectively connected to the moving frame and the air blowing unit; the air outlet of the air blowing unit faces the rotating end of the circular saw unit.

[0011] Preferably, the bonding mechanism includes a wiping part, an inclined rod, an adjustment unit, and a rotating unit; the wiping part is installed at the top of the air blowing unit; the inclined rod is installed inside the workbench and located on the moving path of the air blowing unit; the adjustment unit is installed on the infusion assembly; the rotating unit is installed inside the workbench and is used to adjust the direction of the spray end of the infusion assembly.

[0012] Preferably, the rotating unit includes a drive gear, a rack, and a damping rod; the bottom of the drive gear is elastically connected to the bottom of the inner cavity of the moving frame, and the top is connected to the spray unit; the rack is installed inside the worktable and is located on the moving path of the drive gear; the damping rod is installed on the damping rod.

[0013] Preferably, the adjustment unit includes a drive device, an adjustment plate, an arc plate, and an adjustment rod; the adjustment rod is installed at the bottom of the air blowing unit; the drive device is installed outside the cylinder, the adjustment plate is rotatably connected inside the cylinder and connected to the rotation shaft of the drive device; the bottom end of the adjustment plate passes through the cylinder and connects to the arc plate.

[0014] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: The drive unit is activated, moving the electric circular saw toward the edge of the worktable. Then, the electric circular saw is started to rotate and cut the edge. At this time, the drive gear and rack mesh, so that the spray section faces the wiping section, and the air blowing unit is in contact with the inclined surface of the inclined bar, so that the wiping section is in contact with the outer surface of the electric circular saw. The coolant is sprayed onto the wiping section through the spray section, and the contact between the wiping section and the electric circular saw cools the electric circular saw. This prevents the coolant from being splashed by the electric circular saw and prevents the electric circular saw from overheating due to high-frequency use, which would affect its service life.

[0015] When the electric circular saw is cutting, its sharpness decreases, increasing the resistance it encounters when cutting the edge. This triggers the drive unit to rotate the adjusting plate and the arc plate, reducing the obstruction area of ​​the adjusting plate inside the cylinder. This increases the amount of coolant sprayed from the spray unit, enhancing the cooling effect. The rotation of the arc plate pulls the adjusting rod towards the cylinder, causing the wiping unit to adhere to the surface of the electric circular saw for coolant wiping. This achieves the following: under normal operating conditions, the electric circular saw is sprayed with coolant by the spray unit and dried by the air blowing unit; after prolonged use and decreased sharpness, the coolant spray volume is increased, and the wiping unit is used.

[0017] Example 1, as Figures 1-5 As shown, the present invention proposes a photovoltaic panel frame cutting device, including a worktable 1, a cutting mechanism installed in the worktable 1, and a bonding mechanism installed in the cutting mechanism for cooling the cutting mechanism; the cutting mechanism includes a cutting component, a liquid infusion component, a rotating component, and a bonding component; the cutting component is installed in the worktable 1 and is used to cut the frame; the liquid infusion component is installed in the cutting component and is used to spray coolant; the rotating component is installed in the liquid infusion component and is used to rotate the liquid infusion component; the bonding component is installed in the cutting component and is used to bond the rotating end of the cutting component; after the cutting component cuts the frame, the liquid infusion component sprays coolant onto the rotating end of the cutting component, and then the bonding mechanism blows air onto the rotating end of the cutting component.

[0018] The cutting assembly includes a limiting component 2, a drive unit 3, a moving frame 4, and a circular saw unit; the limiting component 2 is installed on the worktable 1 and is used to limit the frame; the drive unit 3 is installed outside the worktable 1, and the moving frame 4 is set on the output end of the drive unit 3; the circular saw unit is installed on the moving frame 4 and is used to cut the frame; the drive unit 3 can be a lead screw assembly, and starting the drive unit 3 drives the moving frame 4 to move, so that the electric circular saw 7 reciprocates to cut the frame.

[0019] The circular saw unit includes a pressure sensor 5, a support plate 6, and an electric circular saw 7. The pressure sensor 5 is installed on the side of the moving frame 4. The support plate 6 is installed on the test end of the pressure sensor 5. The electric circular saw 7 is installed on the support plate 6. The electric circular saw 7 consists of a motor and a circular saw. The motor is installed on the support plate 6, and the circular saw is installed on the output shaft of the motor.

[0020] The infusion assembly includes a cylinder 8, a telescopic tube 9, an infusion pump 10, an infusion pipe 11, and a spray section 13. The cylinder 8 is installed inside the movable frame 4. The two ends of the telescopic tube 9 are connected to the cylinder 8 and the infusion pump 10, respectively. The infusion pump 10 is installed inside the workbench 1. The infusion pipe 11 is connected to the cylinder 8. The spray section 13 is rotatably connected to the infusion pipe 11. The infusion pump 10 is installed on the workbench 1. When the elastic element 14 moves, the telescopic tube 9 can be stretched to connect the external coolant input source to the input end of the infusion pump 10. Then, the infusion pump 10 is started to deliver coolant along the telescopic tube 9, the cylinder 8, and the infusion pipe 11 to the spray section 13.

[0021] The bonding assembly includes an elastic element 14 and an air blowing unit 15; the two ends of the elastic element 14 are respectively connected to the moving frame 4 and the air blowing unit 15; the air outlet of the air blowing unit 15 faces the rotating end of the circular saw unit; the elastic element 14 consists of a spring and a telescopic rod, with the spring sleeved on the outer periphery of the telescopic rod.

[0022] Example 2, as Figures 2-5 As shown, the photovoltaic panel frame cutting device proposed in this invention, compared with Embodiment 1, has a bonding mechanism including a wiping part 16, an inclined rod 17, an adjustment unit, and a rotating unit; the wiping part 16 is installed at the top of the air blowing unit 15; the inclined rod 17 is installed in the workbench 1 and located on the moving path of the air blowing unit 15; the adjustment unit is installed on the infusion assembly; the rotating assembly is installed in the workbench 1 and is used to adjust the spray direction of the infusion assembly.

[0023] The rotating unit includes a drive gear 12, a rack 22, and a damping rod 23. The bottom of the drive gear 12 is elastically connected to the bottom of the inner cavity of the moving frame 4, and the top is connected to the spray section 13. The rack 22 is installed in the workbench 1 and is located on the moving path of the drive gear 12. The damping rod 23 is installed on the damping rod 23. The drive gear 12 consists of a bottom gear and a top T-bar. The T-bar is connected to the inner wall of the spray section 13. The bottom gear of the drive gear 12 is elastically connected to the bottom of the inner cavity of the moving frame 4 through a coil spring. The elasticity provided by the coil spring can stably drive the spray section 13 to move and reset.

[0024] The rack 22 is located on the movement path of the gear. When the electric circular saw 7 cuts the frame, the drive gear 12 first meshes with the rack 22, rotating the drive gear 12 and causing the spray section 13 to face the wiping section 16. Then, the drive gear 12 transitions from the rack 22 to the damping rod 23. Through the contact between the drive gear 12 and the damping rod 23, the damping rod 23 applies resistance to the drive gear 12, preventing the drive gear 12 from rotating further. A limiting unit can be set to limit the rotation angle of the spray section 13, so that the spray section 13 can only face the wiping section 16 or the electric circular saw 7.

[0025] The adjustment unit includes a drive device 18, an adjustment plate 19, an arc plate 20, and an adjustment rod 21. The adjustment rod 21 is installed at the bottom of the air blowing unit 15. The drive device 18 is installed outside the cylinder 8, and the adjustment plate 19 is rotatably connected inside the cylinder 8 and connected to the rotating shaft of the drive device 18. The bottom end of the adjustment plate 19 passes through the cylinder 8 and connects to the arc plate 20. Under normal circumstances, the electric circular saw 7 is used normally. After the electric circular saw 7 cuts the frame, the infusion pump 10 is started to deliver coolant to the spray section 13, and then sprays it onto the surface of the electric circular saw 7 through the spray section 13. At this time, the air blowing unit 15 blows air onto the surface of the electric circular saw 7 for drying. When the electric circular saw 7 is used for a long time, the electric circular saw 7 becomes dull. At this time, the drive device 18 is started to drive the adjustment plate 19 and the arc plate 20 to rotate. The rotation of the adjustment plate 19 increases the water flow.

[0026] In summary, in this invention, the photovoltaic panel frame is placed above the workbench 1. Then, the limiting component 2 is activated to clamp and fix the frame. Next, the electric circular saw 7 is started to rotate, and at the same time, the drive unit 3 is activated to drive the moving frame 4 to move, so that the rotating electric circular saw 7 moves towards the frame and cuts the frame. At this time, the drive gear 12 moves to the rack 22. Through the meshing of the drive gear 12 and the rack 22, the drive gear 12 is driven to rotate, so that the spraying part 13 turns towards the wiping part 16. At the same time, the blowing unit 15 moves along the inclined surface of the inclined bar 17, so that the blowing unit 15 drives the wiping part 16 to adhere to the surface of the electric circular saw 7. Then, the infusion pump 10 is activated to deliver coolant along the cylinder 8, the telescopic tube 9 and the infusion tube 11 to the spraying part 13. Then, the spraying part 13 sprays the bottom surface of the electric circular saw 7, and the wiping part 16 directly wipes the water stains on the surface of the electric circular saw 7 to prevent the coolant from being splashed out.

[0027] After the electric circular saw 7 finishes cutting, the moving frame 4 returns the electric circular saw 7 to the worktable 1. The spray unit 13 then faces the electric circular saw 7 again, and the coolant is sprayed directly onto the surface of the electric circular saw 7 through the spray unit 13. At this time, the rotation speed of the electric circular saw 7 slows down and it will not be thrown out. Then, the air blowing unit 15 blows air onto the surface of the electric circular saw 7 to dry the coolant.

[0028] If the moving frame 4 drives the rotating electric circular saw 7 to cut the frame, and the electric circular saw 7 becomes dull due to insufficient sharpness, the pressure sensor 5 detects that the support plate 6 experiences significant resistance. At this point, the drive device 18 is activated to rotate the adjusting plate 19, which in turn rotates the arc plate 20. The arc of the arc plate 20 pulls the adjusting rod 21 towards the cylinder 8, causing the air blowing unit 15 and the wiping part 16 to move closer to the electric circular saw 7. This prevents the coolant from flowing out of the electric circular saw 7 too quickly after the coolant level increases, thus enabling the wiping part 16 to be used as needed. This avoids excessive use of the wiping part 16, which could lead to it being damaged by the electric circular saw 7, thereby extending the service life of the wiping part 16.

[0029] The movable frame 4 can be designed to be hollow, and a collection tank for receiving coolant can be installed at the bottom of the workbench 1.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
