Description

Technical Field

[0001] The present invention relates to the technical field of backing plate cutting equipment, and particularly to a special orienting cutting equipment for COP and COC alloy photovoltaic slices Background Art

[0002] COP / COC has high transparency (light transmittance of 91%), low birefringence and low refractive index (1.53), and is suitable for photovoltaic module encapsulation materials or optical protective layers that require high light transmittance. Moreover, it has high heat resistance (Tg reaches 85 - 178°C) and chemical corrosion resistance, and can withstand high temperature, ultraviolet rays and chemical erosion of photovoltaic modules in outdoor environments. Special backing plates are required for the production and processing of COP and COC alloy photovoltaic slices.

[0003] During the production and processing of the special backing plates for COP and COC alloy photovoltaic slices, cutting processing needs to be performed on them. In the existing cutting equipment, tungsten wires are generally used for heating cutting and are combined with guiding equipment to achieve orienting cutting.

[0004] However, in the actual use process of the above equipment, the tungsten wires are generally fixed in a vertical state and powered by a stable power supply to heat the tungsten wires. However, the connection points of the tungsten wires are only its upper and lower endpoints. When continuously pushing the backing plate, the backing plate will also exert a squeezing force on the tungsten wires, making the position where the tungsten wires perform cutting prone to deformation or displacement, thus affecting the cutting accuracy of the backing plate. In view of this, we have proposed a special orienting cutting equipment for COP and COC alloy photovoltaic slices. Summary of the Invention

Four sets of the arc-shaped belts are provided, and the four sets of arc-shaped belts are arranged in a state where the opening directions of adjacent two sets are opposite, so that no matter whether the sleeve wheel and the gasket plate slide leftward or rightward, the arc-shaped belt can inhibit the sliding trend.

[0016] Compared with the prior art, the present invention provides a special orienting cutting device for COP and COC alloy photovoltaic slicing pads, which has the following beneficial effects:

[0017] 1. For the special orienting cutting device for COP and COC alloy photovoltaic slicing pads, by providing an anti-offset assembly, the contact between the tungsten wire and the gasket plate will also receive a rightward thrust in the horizontal direction. At this time, under the limitation of the limiting cylinder and the arc groove, the tungsten wire will not have a large stroke offset in the horizontal direction, thereby avoiding the deformation of the tungsten wire during the cutting process, thus avoiding affecting the cutting accuracy of the gasket plate and improving the service life of the tungsten wire at the same time.

[0018] 2. For the special orienting cutting device for COP and COC alloy photovoltaic slicing pads, during the cutting process, due to the setting of the fitting spring, the sleeve wheel always fits on the surface of the gasket plate. When the gasket plate is offset during the cutting process, the sleeve wheel will move horizontally with the offset gasket plate. At this time, driven by the sleeve wheel and the inner wheel, the toothed rod will drive the gear to rotate. At this time, through the transmission of the gear, the other toothed rod will drive the cross slider, the inner wheel and the sleeve wheel to move in the reverse direction to ensure that the moving directions of the cut plates are relatively moving or moving in the opposite direction, thereby avoiding the offset of the gasket plate towards one side and affecting the subsequent cutting accuracy of the plate.

[0019] 3. The special orientation cutting equipment for the COP and COC alloy photovoltaic slicing special backing plate is provided with an anti-slip component, which cooperates with four groups of arc-shaped belts with opposite opening directions adjacent to each other, so that no matter whether the sliding between the sleeve wheel and the gasket plate occurs towards the left or the right, the arc-shaped belt can inhibit the sliding trend. At the same time, with the setting of the connecting block, the anti-slip and decelerating state of the arc-shaped belt is maintained, avoiding its complete turnover due to anti-slip, and thus affecting the anti-slip effect provided by the sleeve wheel to the gasket plate.

Detailed Embodiment

[0027] As Figures 1-6 shown, the present invention provides a technical solution: a special orientation cutting equipment for the COP and COC alloy photovoltaic slicing special backing plate, including a workbench 1, a guide rail 2 is fixedly installed on the upper surface of the workbench 1, a U-shaped frame 3 is fixedly installed on the upper surface of the workbench 1, a stable power supply 4 is fixedly installed on the upper surface of the U-shaped frame 3, insulating blocks 5 are fixedly installed on the upper surface of the workbench 1 and the lower surface of the top of the U-shaped frame 3, a tungsten wire 6 is fixedly installed on the side wall of the insulating block 5, and an anti-offset component 7 for preventing the tungsten wire 6 from deforming and offsetting is arranged on the surface of the insulating block 5. The anti-offset component 7 includes a sleeve 71, a sliding rod 72, a limiting cylinder 73, a fitting spring 74, a support rod 75, and an arc-shaped groove 76 and a ball 77.

[0028] In an embodiment of the present invention, the sleeve 71 is fixedly installed on the upper surface of the insulating block 5. A sliding rod 72 is slidably installed on the inner wall of the top of the sleeve 71. A limiting cylinder 73 is fixedly installed at the top end of the sliding rod 72. A fitting spring 74 is fixedly connected between the bottom end of the sliding rod 72 and the inner wall of the bottom end of the sleeve 71. A support rod 75 is fixedly connected between the side wall of the sleeve 71 and the outer wall of the insulating block 5. An arc-shaped groove 76 is formed on the surface of the limiting cylinder 73 close to the tungsten wire 6. A ball 77 is movably installed on the inner surface of the arc-shaped groove 76.

[0029] Furthermore, the guide rail 2 is arranged in a U shape, and the number of the guide rails 2 is two groups. The two groups of guide rails 2 are mirror-symmetrically arranged on the left and right sides of the vertical central axis of the workbench 1. A number of contact rollers are rotatably installed on the inner surfaces and the side surfaces of the upper and lower sides of the guide rail 2, so that when the gasket plate is cut, it is inserted along the inner surface of the guide rail 2, and then the contact rollers are used to ensure the transportation of the gasket plate while reducing the wear of the gasket plate. At the same time, the stable power supply 4 is electrically connected to the tungsten wire 6, and a control console is fixedly installed on the upper surface of the workbench 1. Whether the stable power supply 4 supplies power to the tungsten wire 6 can be controlled through the control console. When the tungsten wire 6 is energized, it will generate high temperature. When the gasket plate moves along the guide rail 2 to contact the tungsten wire 6, it can be melted by the heat of the tungsten wire 6, thereby realizing the linear cutting work of the gasket plate. Specifically, the tungsten wire 6 is arranged vertically, and the anti-offset assembly 7 is arranged on the side of the tungsten wire 6 away from the feeding of the gasket plate.

[0030] In addition, a strip-shaped limiting block is fixedly installed on the arc-shaped outer wall of the sliding rod 72, and a limiting chute adapted to the above strip-shaped limiting block is formed on the arc-shaped inner wall of the sleeve 71, so that only relative displacement in the vertical direction can occur between the sliding rod 72 and the sleeve 71, and no relative rotation will occur, thereby enabling the limiting cylinder 73 to better provide a limiting and stable effect for the tungsten wire 6. At the same time, the inside of the limiting cylinder 73 is hollow, and a number of leakage holes are formed on the arc-shaped outer wall of the limiting cylinder 73, so that the limiting cylinder 73 is integrally arranged as a cylindrical hollow frame, so that while the overall weight of the limiting cylinder 73 is reduced, too much heat will not accumulate inside it, and the heat entering it can be dissipated in the air, and will not be transmitted along the limiting cylinder 73 to the workbench 1 or the U-shaped frame 3, thereby affecting the normal use of other accessories. Furthermore, a relatively stable triangle is formed among the support rod 75, the insulating block 5 and the sleeve 71, thereby improving the lateral anti-torsion force of the structure formed by the sleeve 71, the sliding rod 72 and the limiting cylinder 73, and preventing it from tilting and affecting the shape retention of the tungsten wire 6.

[0031] Meanwhile, the width of the arc-shaped groove 76 is greater than the outer diameter of the tungsten wire 6, and the arc-shaped groove 76 is arranged vertically so that the tungsten wire 6 can just be wrapped by the arc-shaped groove 76. Further, multiple sets of balls 77 are provided, and the multiple sets of balls 77 are evenly distributed in a linear array on the inner wall of the arc-shaped groove 76. And the number of each set of balls 77 is three, and the three balls 77 are arranged in an arc array on the inner surface of the arc-shaped groove 76, so that the contact between the tungsten wire 6 and the arc-shaped groove 76 is realized through the balls 77, so that the up and down movement of the limiting cylinder 73 will not cause wear to the surface of the tungsten wire 6 and affect the service life of the tungsten wire 6.

[0032] Please refer to the attached Figures 3-5 On the surface of the end of the limiting cylinder 73 far from the sliding rod 72, a centering component 8 is provided. The centering component 8 includes a mounting ear 81, and the mounting ear 81 is fixedly installed on the outer wall of the end of the limiting cylinder 73 far from the sliding rod 72. The inner wall of the mounting ear 81 penetrates and is fixedly installed with a fixing sleeve 82. A round rod 83 is fixedly installed on the inner wall of the end of the fixing sleeve 82. A cross-shaped sliding frame 84 is slidably installed through the outer wall of the round rod 83. An inner wheel 86 is fixedly installed at the end of the cross-shaped sliding frame 84. A connecting spring 85 is fixedly connected between the cross-shaped sliding frame 84 and the inner wall of the end of the fixing sleeve 82. A sleeve wheel 87 is rotatably installed on the outer surface of the inner wheel 86. A rack 88 is fixedly installed at the end of the cross-shaped sliding frame 84 far from the connecting spring 85. A gear 89 is rotatably installed on the inner wall of the fixing sleeve 82.

[0033] Specifically, two sets of mounting ears 81 are provided to ensure the horizontal installation of the fixing sleeve 82. At the same time, rectangular grooves adapted to the width of the connecting part between the cross-shaped sliding frame 84 and the inner wheel 86 are opened on the upper and lower inner walls of the fixing sleeve 82, so that the cross-shaped sliding frame 84 can drive the inner wheel 86 to move horizontally along the outer surface of the fixing sleeve 82. Further, the inner wheel 86 is sleeved on the outer surface of the fixing sleeve 82 so that relative sliding can occur between the inner wheel 86 and the fixing sleeve 82 in the horizontal direction without relative rotation. Specifically, annular grooves are opened on both sides of the inner wheel 86, and limiting rings adapted to the above annular grooves are provided on the left and right inner surfaces of the sleeve wheel 87, and the limiting rings are arranged in the annular grooves, so that relative rotation can occur between the sleeve wheel 87 and the inner wheel 86 when the sleeve wheel 87 is sleeved outside the inner wheel 86.

[0034] Meanwhile, the connecting spring 85 is sleeved outside the round rod 83 to prevent the connecting spring 85 from deflecting in the vertical direction, thereby affecting the contraction and release of the elastic force of the connecting spring 85. Further, the number of the round rod 83, the cross slide 84, the connecting spring 85, the inner wheel 86 and the sleeve wheel 87 is set to two groups, and the two groups of round rod 83, cross slide 84, connecting spring 85, inner wheel 86 and sleeve wheel 87 are mirror-symmetrically arranged with the vertical central axis of the fixed sleeve 82 as the axis of symmetry. At the same time, the number of the toothed rods 88 is set to two groups, and the two groups of toothed rods 88 are centrosymmetrically arranged with the axis of the gear 89 as the center of symmetry. Specifically, the two groups of toothed rods 88 are respectively engaged with the top and bottom teeth of the gear 89 to achieve transmission. During the cutting process, due to the arrangement of the fitting spring 74, the sleeve wheel 87 always fits on the surface of the gasket plate. When the gasket plate deviates during the cutting process, the sleeve wheel 87 will move laterally with the deviating gasket plate. At this time, driven by the sleeve wheel 87 and the inner wheel 86, the toothed rod 88 will drive the gear 89 to rotate. At this time, through the transmission of the gear 89, the other toothed rod 88 will drive the cross slide 84, the inner wheel 86 and the sleeve wheel 87 to move in the opposite direction to ensure that the moving direction of the cut plate is relatively moving or moving in the opposite direction, so as to prevent the gasket plate from deviating towards one side and affecting the subsequent cutting accuracy of the plate.

[0035] Please refer to the attached instructions Figures 5-6 On the outer surface of the sleeve wheel 87, an anti-slip component 9 is provided. The anti-slip component 9 includes an annular arc groove 91. On the inner surface of the annular arc groove 91, an arc-shaped belt 92 is fixedly installed. On the inner surface of the arc-shaped belt 92, a connecting block 93 is fixedly installed.

[0036] In the embodiment of the present invention, the annular arc groove 91 is opened at the center of the arc-shaped outer surface of the sleeve wheel 87, so that when the outer surface of the sleeve wheel 87 contacts the surface of the gasket plate, the contact surface is in a C shape, which has a preliminary anti-offset effect on the gasket plate in the horizontal direction. At the same time, the number of the arc-shaped belts 92 is set to four groups, and the four groups of arc-shaped belts 92 are arranged in a state where the opening directions of adjacent two groups are opposite, so that no matter whether the sleeve wheel 87 and the gasket plate slide towards the left or the right, the arc-shaped belt 92 can inhibit the sliding trend. Further, the number of the connecting blocks 93 is set to several, and the several connecting blocks 93 are evenly distributed in a circumferential array on the arc-shaped inner surface of the arc-shaped belt 92, so as to maintain the shape of the arc-shaped belt 92 and prevent it from being completely turned over due to anti-slip, thereby affecting the anti-slip effect provided by the sleeve wheel 87 on the gasket plate.

[0037] In the present invention, during use, first, the stable power supply 4 is controlled to be turned on through the console to energize the tungsten wire 6. After the tungsten wire 6 is energized for a certain period of time, when the temperature of the tungsten wire 6 reaches the required cutting temperature measured by the measuring device, the staff inserts the gasket sheet along the inner surface of the guide rail 2, and then uses the contact roller to reduce the wear of the gasket sheet while ensuring the transportation of the gasket sheet, and cooperates with the high-temperature tungsten wire 6 to achieve precise cutting of the gasket sheet. At the same time, through the anti-offset component 7 provided, the contact between the tungsten wire 6 and the gasket sheet will also receive a rightward thrust in the horizontal direction. At this time, under the limitation of the limiting cylinder 73 and the arc-shaped groove 76, the tungsten wire 6 will not have a large offset in the horizontal direction, thereby avoiding the deformation of the tungsten wire 6 during the cutting process, thus avoiding affecting the cutting accuracy of the gasket sheet and improving the service life of the tungsten wire 6 at the same time.

[0038] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
