Description
Technical Field

[0002] Solar photovoltaic cells, also known as photovoltaic cells, are used to convert sunlight directly into electrical energy. Ground photovoltaic systems use a large number of silicon-based silicon solar cells, which can be divided into single-crystal silicon, polycrystalline silicon, and amorphous silicon solar cells. In terms of comprehensive performance such as energy conversion efficiency and service life, single-crystal silicon and polycrystalline silicon cells are superior to amorphous silicon cells. Polycrystalline silicon has a lower conversion efficiency than single-crystal silicon, but is cheaper. Specifically, in the production process of photovoltaic cells, photovoltaic glass needs to be rolled, annealed, cut, coated, and tempered. The above-mentioned photovoltaic glass inevitably needs to be flipped and conveyed during a series of processing processes. For example, in the coating operation, both sides of the photovoltaic glass need to be coated at the same time, which requires the photovoltaic glass to be flipped during transportation to ensure its use in the working position; the existing flipping method is to flip it through two sets of manipulators in cooperation with vacuum suction cups. In actual operation, the suction cups can only cover local positions of the photovoltaic glass, and the coverage area is small, which leads to the photovoltaic glass being easily subjected to excessive local force during the flipping process; this can easily cause hidden cracks inside the photovoltaic glass, resulting in a decline in the quality of the photovoltaic glass.

DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0021] like Figures 1 to 5 As shown, a photovoltaic cell production device according to an embodiment of the present invention comprises a first conveyor 1 and a second conveyor 2, wherein the first conveyor 1 and the second conveyor 2 are on the same conveying straight line; a pair of brackets 3 are arranged between the unloading end of the first conveyor 1 and the loading end of the second conveyor 2, a support shaft 31 is rotatably connected between the pair of brackets 3, a first motor 32 mounted on the bracket 3 is arranged at the end of the support shaft 31, a sleeve 33 is sleeved on the surface of the support shaft 31, a plurality of docking plates 34 are evenly fixed to the annular circumference of the sleeve 33, a docking notch 35 is provided at one end of the docking plate 34 away from the sleeve 33, and the inner diameter distance of the docking notch 35 is equal to the thickness of the photovoltaic glass to be flipped; At present, when flipping the photovoltaic glass during the conveying process, two sets of manipulators cooperate with vacuum suction cups to flip it. During operation, the suction cups can only cover the local position of the photovoltaic glass, and the coverage area is small, which leads to the situation that the photovoltaic glass is easily subjected to excessive force locally during the flipping process; and thus, it is easy to cause hidden cracks inside the photovoltaic glass, resulting in a decrease in the quality of the photovoltaic glass. In order to solve the above problems, the embodiment of the present invention is provided with structures such as a support shaft 31, a sleeve 33, and a docking plate 34, and the specific use process is as follows; When in use, the first conveyor 1 conveys the photovoltaic glass in the direction of the second conveyor 2. When the photovoltaic glass is conveyed to the unloading end of the first conveyor 1, the end of the photovoltaic glass gradually separates from the first conveyor 1. At this time, the opening of the docking notch 35 on the docking plate 34 is located at the unloading end of the first conveyor 1 and is at the same height as the photovoltaic glass. Therefore, when the photovoltaic glass is gradually unloaded, one end of the photovoltaic glass will gradually be inserted into the docking notch 35. When the photovoltaic glass is inserted into the deepest part of the docking notch 35, the first motor 32 drives the docking plate 34 to rotate 180 degrees clockwise through the support shaft 31 and the sleeve 33. At this time, part of the photovoltaic glass is located in the docking notch 35 and part is located outside the docking notch 35. When the docking plate 34 rotates, the photovoltaic glass in the docking notch 35 rotates synchronously. When rotating 180 degrees, the photovoltaic glass outside the docking notch 35 is placed on the feeding end of the second conveyor 2, and as the second conveyor 2 operates, the photovoltaic glass in the docking notch 35 The glass is driven out by friction and finally fully loaded onto the top of the second conveyor 2. It should be noted that when the photovoltaic glass enters and leaves the docking notch 35, the photovoltaic glass remains in a horizontal state to ensure full contact with the first conveyor 1 and the second conveyor 2. When the sleeve 33 drives the docking plate 34 close to the first conveyor 1 to rotate one hundred and eighty degrees, the docking plate 34 close to the second conveyor 2 will rotate to the side close to the unloading end of the first conveyor 1, for the subsequent reception of the photovoltaic glass transported by the first conveyor 1. The above process can be repeated to cyclically flip the photovoltaic glass. During flipping, since the inner diameter distance of the docking notch 35 is equal to the thickness of the photovoltaic glass to be flipped, the flipping torque of the photovoltaic glass is provided by the docking notch 35, and the inner wall of the docking notch 35 will fully contact the surface of the photovoltaic glass, avoiding excessive local force on the photovoltaic glass, effectively protecting the photovoltaic glass during flipping, and greatly reducing the possibility of hidden cracks when the photovoltaic glass is flipped.
[0022] like Figures 3 to 12As shown, a pair of rectangular through holes 36 penetrating into the docking notch 35 are provided on both sides of the docking plate 34, and a friction roller 41 is arranged inside the rectangular through hole 36. A pair of rotating shafts 42 are arranged at both ends of the friction roller 41, and the ends of the rotating shafts 42 away from the friction roller 41 are rotatably connected to a fixing plate 43, and the fixing plate 43 is fixedly connected to the surface of the docking plate 34; a driven gear 44 is sleeved on the surface of the rotating shaft 42, and a driving gear 45 is meshingly connected to the meshing surface of the driven gear 44, and a second motor 4 installed on the surface of the docking plate 34 is connected to the side of the driving gear 45; a part of the friction roller 41 is located inside the docking notch 35; When the photovoltaic glass enters the docking gap 35 through the friction force with the first conveyor 1, the second motor 4 is started, and the second motor 4 drives the driving gear 45 to rotate, and the driving gear 45 drives the driven gear 44 meshing therewith to rotate, and the driven gear 44 drives the friction roller 41 to rotate through the rotating shaft 42, and part of the friction roller 41 is located inside the docking gap 35, and the friction roller 41 is made of deformable rubber, so the roller surface of the friction roller 41 will be squeezed to the surface of the photovoltaic glass in the docking gap 35. As the friction roller 41 rotates, the friction roller 41 drives the photovoltaic glass to move into the docking gap 35 through friction. When the photovoltaic glass is transferred to the second conveyor 2, the friction roller 41 rotates in the opposite direction to drive the photovoltaic glass to disengage from the docking gap 35, which is beneficial to improving the smoothness of loading and unloading of the photovoltaic glass.
[0023] The friction roller 41 includes a center roller 411; a plurality of plug-in grooves 412 are provided on the annular circumference of the center roller 411, and a plug-in column 413 is plugged into the inside of the plug-in groove 412, and a buffer spring 415 is provided between one end of the plug-in column 413 located inside the plug-in groove 412 and the inner wall of the plug-in groove 412, and a rubber strip 414 is provided at the end of the plug-in column 413 located outside the plug-in groove 412; when the friction roller 41 rotates, the center roller 411 drives the rubber strip 414 to rotate synchronously through the cooperation between the plug-in groove 412 and the plug-in column 413, and when the rubber strip 414 rotates, sliding friction is generated with the surface of the photovoltaic glass, and the buffer spring 415 is deformed. By replacing the rubber strips 414 of different sizes, the pressure of the rubber strip 414 on the photovoltaic glass can be changed, and the driving effect of the friction roller 41 on the photovoltaic glass can be adjusted; this is conducive to the use of flipping photovoltaic glass of different sizes.
[0024] A pair of receiving frames 5 are symmetrically arranged at the end of the docking plate 34 away from the sleeve 33 based on the docking notch 35, and an expansion airbag 51 is arranged at the end of the receiving frame 5 facing the docking notch 35. A first conduit 52 is connected to the side of the expansion airbag 51, and an end of the first conduit 52 away from the expansion airbag 51 is connected to an air pump 53 installed on the surface of the docking plate 34; when the docking plate 34 rotates, the air pump 53 is started, and the air pump 53 inflates the expansion airbag 51 on the receiving frame 5 through the first conduit 52. When the expansion airbag 51 expands, it squeezes the surface of the photovoltaic glass outside the docking notch 35. The expansion airbags 51 on both sides of the photovoltaic glass squeeze symmetrically, so that the photovoltaic glass is restricted, thereby preventing the photovoltaic glass from being thrown out of the docking notch 35 due to centrifugal force when it rotates.
[0025] A second conduit 54 is provided on the side of the first conduit 52, and a pressure relief valve 55 installed on the surface of the docking plate 34 is provided at the end of the second conduit 54 away from the first conduit 52; when the expansion airbag 51 is inflated, when the internal air pressure of the expansion airbag 51 reaches a certain level, the gas in the first conduit 52 will be discharged through the pressure relief valve 55 connected to the second conduit 54, so that the expansion airbag 51 maintains a stable air pressure, thereby preventing the expansion airbag 51 from squeezing the photovoltaic glass too much and causing damage to the photovoltaic glass.
[0026] like Figures 13 to 15 As shown, the bracket 3 includes a support plate 301, and the support shaft 31 is rotatably connected between a pair of support plates 301; a connecting piece 302 is provided at the bottom end of the support plate 301, and a pad 303 is provided at the bottom end of the connecting piece 302, and two pairs of rollers 304 with vertical moving directions are provided on the side of the pad 303, and a plurality of output motors are provided on the surface of the pad 303; the plurality of output motors are used to drive the plurality of rollers 304; when the position of the first conveyor 1 is far away from the position of the second conveyor 2, the staff controls the rollers 304 installed on the pad 303 to roll through the output motor, so that after the photovoltaic glass enters the docking notch 35, the pad 303 drives the support shaft 31 to move, and stops when the docking plate 34 is aligned with the feeding end of the second conveyor 2, and then the flipped photovoltaic glass is fed onto the second conveyor 2; the arrangement of the above structure improves the scope of application of the overall equipment; and is convenient for the staff to operate.
[0027] A pair of fixing frames 6 are provided on the side of the support plate 301 facing the support shaft 31, and the pair of fixing frames 6 are symmetrical based on the support shaft 31; a first hydraulic cylinder 61 is provided on the side of the fixing frame 6 away from the support shaft 31, and an arc plate 62 is provided at the end of the output end of the first hydraulic cylinder 61, and the inner concave surface of the arc plate 62 can fit with the rotation part of the feeding end of the second conveyor 2, and the center of the inner concave surface of the arc plate 62 is at the same height as the center of the docking notch 35 in a horizontal state; when the mobile pad 303 drives the docking plate 34 close to the second conveyor When the feeding end of the second conveyor 2 is reached, the first hydraulic cylinder 61 is started, and the output of the first hydraulic cylinder 61 is preset. Then the arc plate 62 is controlled to approach the corner of the second conveyor 2. When the arc plate 62 is completely fitted into the rotation point of the feeding end of the second conveyor 2, it stops. At this time, the docking notch 35 on the docking plate 34 is aligned with the feeding end of the second conveyor 2; then the arc plate 62 can be withdrawn. The arrangement of the above structure facilitates the alignment process of the docking notch 35 on the docking plate 34 with the feeding end of the second conveyor 2.
[0028] A pair of circular through holes 63 are provided on the side of the arc plate 62 based on the central symmetry. A detection block 64 is inserted into the circular through hole 63. A telescopic spring 65 is provided at one end of the detection block 64 located in the circular through hole 63. A pressure sensor 66 is provided at one end of the telescopic spring 65 away from the detection block 64. A connecting frame 67 is provided on the side of the pressure sensor 66. The connecting frame 67 is fixedly connected to the surface of the arc plate 62. When the concave arc surface of the arc plate 62 is pressed against the rotation point of the feeding end of the second conveyor 2, the detection block 64 located outside the circular through hole 63 is first pressed. It is squeezed into the circular through hole 63, and the detection block 64 squeezes the pressure sensor 66 through the telescopic spring 65. When the pressure sensor 66 is squeezed, the staff checks the value; and compares the displayed values of a pair of pressure sensors 66 on the arc plate 62. When the displayed values are different, it means that the height of the arc plate 62 is not compatible with the second conveyor 2, so the height of the docking plate 34 is also not compatible with the second conveyor 2. Therefore, the staff needs to adjust the height of the docking plate 34 so that the displayed values of the pair of pressure sensors 66 on the arc plate 62 are the same, thereby improving the docking accuracy.
[0029] The connecting member 302 is specifically a second hydraulic cylinder; the second hydraulic cylinder is installed on the top of the pad 303, and the top of the second hydraulic cylinder output end is connected to the bottom of the support plate 301; the second hydraulic cylinder is convenient for the staff to adjust the height of the docking plate 34, which is convenient for the staff to operate.
[0030] The concave arc surface of the arc plate 62 is set as a smooth surface; when the docking plate 34 is controlled to dock with the second conveyor 2, the second conveyor 2 may be running. When the arc plate 62 is pressed against the rotating part of the feeding end of the second conveyor 2, the running conveyor belt and the arc plate 62 produce friction. Therefore, the concave arc surface of the arc plate 62 is set as a smooth surface to reduce the friction force of the conveyor belt during operation and ensure the smooth operation of the second conveyor 2.
[0031] It should be pointed out that the starting of the motor and the output of the hydraulic cylinder in the technical solution of the present invention are controlled by a microcomputer.
