Description

Technical Field

[0001] This invention relates to the field of solar cell sorting technology, and more specifically to a solar cell sorting device. Background Technology

[0002] A solar cell is a thin film of photovoltaic semiconductor that directly generates electricity using sunlight. Also known as a "solar chip" or "photovoltaic cell," it can instantly output voltage and generate current when a circuit is present, provided certain illumination conditions are met. Solar cells are devices that directly convert light energy into electrical energy through the photoelectric effect or photochemical effect. Crystalline silicon solar cells, which operate based on the photovoltaic effect, are the mainstream. Solar cell sorting is the first and most important step in solar cell module production. Currently, photovoltaic companies widely use solar cell sorting machines for this purpose. The production process of solar cells is complex, and the produced cells often have uneven color. Color sorting is necessary to ensure the photoelectric conversion efficiency of the cells. Initial sorting removes cells with defects such as missing corners, poor grid printing, cracks, and color differences, ensuring module quality and smooth, efficient production. Color sorting generally relies on manual inspection, which has low effectiveness, and frequent contact with the cells can cause contamination, affecting product quality. Therefore, we have proposed a solar cell sorting device. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a solar cell sorting device, including a housing, a sorting mechanism disposed on the upper part of the inner wall of the housing, a driving mechanism disposed on the bottom of the inner wall of the housing, the sorting mechanism being composed of a disk body disposed inside the housing, a rotating column disposed at the axis of the disk body, and the inner wall of the disk body being fixedly connected to the middle outer surface of the rotating column, a fixing plate being rotatably connected to the end of the rotating column away from the housing, a CCD detector being embedded in the center of the fixing plate, a placement component disposed on the top of the disk body, and the placement component being arranged parallel to the CCD detector, the space between the disk body and the driving mechanism being... The system is equipped with a separating component. A rotating column is driven by a drive mechanism to place solar cells inside the placement component. The placement component rotates under the drive of the rotating column. A CCD detector inspects the solar cells rotating with the placement component, thereby filtering out solar cells with color differences or damage. The drive mechanism consists of a support frame, which is fixedly connected to the bottom of the inner wall of the outer casing. A motor is fixedly connected to the inner wall of the support frame. A rotating shaft is fixedly connected to the side of the motor away from the bottom of the inner wall of the outer casing, and the rotating shaft is fixedly connected to the output end of the motor. The drive mechanism uses the motor as the driving force to drive the sorting mechanism to operate. The rotation of the motor's output end drives the rotating shaft to rotate.

[0004] Furthermore, a drive gear is provided at the end of the rotating shaft away from the motor. The shaft center of the drive gear is fixedly connected to the outer surface of the rotating shaft, and the number of teeth of the drive gear is evenly spaced in several groups, with several teeth in each group. The rotation of the rotating shaft drives the drive gear to rotate, and the rotation of the drive gear drives the driven gear to rotate. By setting an incomplete gear structure for the drive gear, the drive gear meshes with the driven gear intermittently, and the sorting mechanism operates intermittently, so that the solar panel rotates intermittently with the placement component, thereby providing sufficient shooting and detection time for the CCD detector and avoiding sorting errors caused by blurry images captured by the CCD detector during rotation.

[0005] Furthermore, the driving mechanism also includes a driven gear, which meshes with the driving gear. A column is rotatably connected to the axis of the driven gear, and the column is fixedly connected to the bottom of the inner wall of the housing. A fixing ring is provided on the side of the driven gear near the bottom of the inner wall of the housing, and the fixing ring is fixedly connected to the outer surface of the column. A fixing rod is fixedly connected to the outer surface of the fixing ring, and the end of the fixing rod away from the fixing ring is fixedly connected to the bottom of the inner wall of the housing. Several fixing rods are arranged along the circumference of the fixing ring, and the end of the column away from the fixing ring passes through... The rotating column is fixedly connected to the outer surface of the fixed plate. The rotation of the driving gear drives the driven gear to rotate intermittently, which in turn drives the rotating column to rotate intermittently. This intermittent rotation of the rotating column drives the disk to rotate intermittently, thereby causing the solar panel to rotate intermittently with the placed components. The fixed plate is fixed to the inner wall of the outer shell through the column, so that the CCD detector will not move with it. By setting a fixing ring and several fixing rods, the connection between the column and the outer shell is made more stable, avoiding the shaking and vibration caused by the rotation of the driven gear and rotating column outside the column, which would affect the imaging and detection effect of the CCD detector.

[0006] Furthermore, the placement assembly includes a telescopic rod, which is fixedly connected to the side of the disc body near the fixed plate. A first rotating plate is fixedly connected to the end of the telescopic rod away from the disc body. A first rotating seat is rotatably connected to the side of the first rotating plate away from the telescopic rod via a rotating rod. A placement frame is fixedly connected to the side of the first rotating seat away from the first rotating plate. A second rotating seat is fixedly connected to the end of the placement frame near the rotating column. A second rotating plate is rotatably connected to the inner wall of the second rotating seat via a rotating rod, and the end of the second rotating plate away from the second rotating seat is fixedly connected to the outer surface of the rotating column. (Image captured by CCD detector) After detecting solar cells with color differences or damage, the corresponding telescopic rod is retracted, causing the placement frame to rotate around the second rotating plate. The placement frame gradually changes from tilting upwards to tilting downwards, while the defective solar cells slide out from inside the placement frame into the first collection tank. The placement frame containing intact solar cells continues to rotate, and the intact solar cells are similarly placed into the second collection tank, separating the superior and inferior products. At the same time, it is necessary to prevent the inspected solar cells from coming into contact with the operators, causing contamination or even damage, to ensure that the selected intact solar cells are not contaminated after sorting.

[0007] Furthermore, the placement frame is equipped with several rollers inside, and both ends of the rollers are rotatably connected to the inner wall of the placement frame. The placement frame is equipped with a limiting component. When the solar cell is placed inside the placement frame, it slides downward under the action of gravity. As the rollers rotate, the solar cell is finally limited and locked by the limiting component. By setting the rollers, damage caused by sliding friction inside the placement frame is avoided. At the same time, the rolling resistance of the rollers is smaller, and they can smoothly reach the limiting component for limiting, so that they can be detected by the CCD detector at a fixed position, thereby improving the detection effect.

[0008] Furthermore, the limiting component includes limiting plates symmetrically arranged inside the placement frame and fixedly connected to the inner wall of the placement frame. Several limiting blocks are provided on the side of the two limiting plates that are close to each other, and these limiting blocks are fixedly connected to the inner wall of the limiting plates. When the solar cell contacts the limiting blocks on both sides, the limiting plates slightly deform, locking the solar cell in place, thereby restricting the position of the solar cell. This ensures that the positions of the solar cells to be detected are approximately the same, facilitating CCD inspection and reducing the need to adjust the CCD inspection instrument to align with the item being inspected, thus saving manual labor and providing convenience.

[0009] Furthermore, a spring plate is symmetrically arranged on the side of the limiting plate away from the limiting block. The two ends of the spring plate are fixedly connected to the outer surface of the limiting plate, and the side of the spring plate away from the limiting plate is fixedly connected to the inner wall of the placement frame. A deformation groove is formed on the surface of the spring plate near the telescopic rod, and the deformation groove is formed on the side of the spring plate near the limiting plate. Under the elastic force of the spring plate, the spring plate supports the limiting plate, preventing the limiting plate from deforming significantly and squeezing the solar cell, thus preventing damage to the solar cell. At the same time, the deformation groove on the surface of the spring plate near the telescopic rod makes the spring plate more prone to deformation. Under the pressure of the solar cell, the spring plate deforms, thereby the limiting block slightly clamps the solar cell, limiting it without damaging the solar cell.

[0010] Furthermore, each of the limiting plates is fixedly connected to a sliding rod on the side away from the limiting block, and the sliding rod is positioned at the interval between the two spring plates. The end of the sliding rod away from the limiting plate passes through the placement frame and slides inside it. The end of the sliding rod outside the placement frame is fixedly connected to an adapter plate. The side of the disk body near the adapter plate is fixedly connected to an adapter block, and the adapter block and the adapter plate cooperate with each other. As the placement frame gradually changes from tilting upwards to tilting downwards, the adapter block and the adapter plate gradually cooperate, and the two adapter plates move away from each other, causing the two sliding rods to move away from each other, which in turn causes the two limiting plates to move away from each other. The limiting component releases the solar cell, and the solar cell slides out of the placement frame, preventing the solar cell from getting stuck inside the placement frame and causing the device to be blocked and affecting its use.

[0011] Furthermore, the separating component includes a first collecting groove with connecting blocks fixedly connected to both ends. A second collecting groove is provided on the side of the connecting blocks away from the first collecting groove, and the two ends of the second collecting groove are respectively fixedly connected to the outer surfaces of the two connecting blocks. Connecting plates are fixedly connected to the sides of the first collecting groove and the second collecting groove near the rotating column, and the connecting plates are fixedly connected to the outer surface of the rotating column. Plastic baffles are fixedly connected to the sides of the first collecting groove and the second collecting groove near the disc. By manipulating different telescopic rods, according to the detection results of the CCD detector, superior and inferior products are respectively placed into the first collecting groove and the second collecting groove to achieve the sorting operation. At the same time, by setting up plastic baffles, the solar cells are prevented from being ejected due to vibration and damaged.

[0012] Furthermore, the inner walls of both the first and second collection tanks are slidably connected to sliding plates, with the middle of the sliding plates protruding upwards. The inner walls of both the first and second collection tanks are fixedly connected to springs. The side of the sliding plate away from the plastic baffle is fixedly connected to the spring. When a solar cell falls onto the surface of the sliding plate, due to the upward protrusion of the middle of the sliding plate, the solar cell slides downwards on the surface of the sliding plate for a certain distance. As the solar cell continues to fall, the spring compresses and rebounds, generating vibration. The previous solar cell continues to slide downwards due to the vibration, thereby gradually arranging the solar cells onto the surface of the sliding plate and preventing the solar cells from accumulating and clogging on the surface of the sliding plate.

[0013] The beneficial effects of this invention are as follows:

[0014] This invention incorporates a drive gear, where the rotating shaft drives the drive gear to rotate, which in turn drives the driven gear to rotate. By employing an incomplete gear structure for the drive gear, the drive gear intermittently meshes with the driven gear, causing the sorting mechanism to operate intermittently. This allows the solar panel to rotate intermittently along with the placement components, thus providing sufficient time for the CCD detector to capture and inspect the image, preventing sorting errors caused by blurry images captured by the CCD detector during rotation.

[0015] This invention incorporates a limiting component. Under the elastic force of a spring plate, the spring plate supports the limiting plate, preventing significant deformation of the limiting plate from squeezing and damaging the solar cells. Simultaneously, a deformation groove is formed on the surface of the spring plate near the telescopic rod, making it easier for the spring plate to deform. Under the pressure of the solar cells, this deformation causes the spring plate to slightly clamp the solar cells, limiting their position without damaging them. By restricting the position of the solar cells, the positions of the solar cells to be inspected are made approximately the same, facilitating CCD inspection and reducing the need for adjusting the CCD to align with the object being inspected, thus saving manual labor and providing convenience.

[0016] This invention uses an adapter plate. As the placement frame gradually tilts from upward to downward, the adapter block and the adapter plate gradually cooperate. The two adapter plates move away from each other, causing the two sliding rods to move away, which in turn causes the two limiting plates to move away from each other. The limiting components release the solar cell, and the solar cell slides out of the placement frame, preventing the solar cell from getting stuck inside the placement frame and causing the device to be blocked and affecting its use.

[0017] This invention uses a sliding plate. Solar cells fall onto the surface of the sliding plate. Because the middle of the sliding plate is raised, the solar cells slide down the surface of the sliding plate a certain distance. As the solar cells continue to fall, the spring is compressed and rebounds, generating vibration. The previous solar cell continues to slide down due to the vibration, thereby gradually arranging the solar cells on the surface of the sliding plate and avoiding the accumulation and blockage of solar cells on the surface of the sliding plate.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose. Example 1

[0028] Please see Figures 1-3 This invention relates to a solar cell sorting device, comprising a housing 1, a sorting mechanism 2 disposed on the upper part of the inner wall of the housing 1, and a driving mechanism 3 disposed on the bottom of the inner wall of the housing 1. The sorting mechanism 2 is composed of a disk 21 disposed inside the housing 1. A rotating column 22 is disposed at the axis of the disk 21, and the inner wall of the disk 21 is fixedly connected to the outer surface of the middle part of the rotating column 22. A fixing plate 23 is rotatably connected to the end of the rotating column 22 away from the housing 1. A CCD detector 24 is embedded in the center of the fixing plate 23. A placement component 25 is disposed on the top of the disk 21, and the placement component 25 is arranged parallel to the CCD detector 24. A separating component 26 is disposed at the interval between the disk 21 and the driving mechanism 3. Driven by the driving mechanism 3, the solar cells are placed inside the placement assembly 25. The placement assembly 25 rotates under the drive of the rotating column 22. The CCD detector 24 detects the solar cells that rotate with the placement assembly 25, thereby screening out solar cells with color difference or damage. The driving mechanism 3 consists of a support frame 31, which is fixedly connected to the bottom of the inner wall of the outer shell 1. A motor 32 is fixedly connected to the inner wall of the support frame 31. A rotating shaft 33 is fixedly connected to the side of the motor 32 away from the bottom of the inner wall of the outer shell 1, and the rotating shaft 33 is fixedly connected to the output end of the motor 32. The driving mechanism 3 drives the sorting mechanism 2 to operate with the motor 32 as the driving force. The output end of the motor 32 rotates, driving the rotating shaft 33 to rotate.

[0029] A drive gear 34 is provided at the end of the rotating shaft 33 away from the motor 32. The shaft of the drive gear 34 is fixedly connected to the outer surface of the rotating shaft 33. The drive gear 34 has several groups of teeth evenly spaced, with several teeth in each group. The rotation of the rotating shaft 33 drives the drive gear 34 to rotate, and the rotation of the drive gear 34 drives the driven gear 35 to rotate. By setting the incomplete gear structure of the drive gear 34, the drive gear 34 meshes with the driven gear 35 intermittently, and the sorting mechanism 2 operates intermittently, so that the solar panel rotates intermittently with the placement component 25, thereby providing sufficient shooting and detection time for the CCD detector 24 and avoiding sorting errors caused by blurry images captured by the CCD detector 24 during rotation.

[0030] The driving mechanism 3 also includes a driven gear 35, which meshes with the driving gear 34. A column 36 is rotatably connected to the axis of the driven gear 35, and the column 36 is fixedly connected to the bottom of the inner wall of the outer casing 1. A fixing ring 37 is provided on the side of the driven gear 35 near the bottom of the inner wall of the outer casing 1, and the fixing ring 37 is fixedly connected to the outer surface of the column 36. A fixing rod 38 is fixedly connected to the outer surface of the fixing ring 37. The end of the fixing rod 38 away from the fixing ring 37 is fixedly connected to the bottom of the inner wall of the outer casing 1, and several fixing rods 38 are arranged along the circumference of the fixing ring 37. The end of the column 36 away from the fixing ring 37 passes through the rotating column 22 and is connected to the fixing plate 23. The outer surface is fixedly connected. The rotation of the drive gear 34 drives the driven gear 35 to rotate intermittently. The intermittent rotation of the driven gear 35 drives the rotating column 22 to rotate intermittently. The intermittent rotation of the rotating column 22 drives the disk 21 to rotate intermittently, thereby causing the solar panel to rotate intermittently with the placement component 25. The fixing plate 23 is fixed to the inner wall of the outer shell 1 by the column 36, so that the CCD detector 24 will not move with it. By setting the fixing ring 37 and several fixing rods 38, the connection between the column 36 and the outer shell 1 is more stable, and the shaking and vibration caused by the rotation of the driven gear 35 and the rotating column 22 on the outside of the column 36 will not affect the shooting and detection effect of the CCD detector 24. Example 2

[0031] Please see Figures 4-8 The placement assembly 25 includes a telescopic rod 251, which is fixedly connected to the side of the disc body 21 near the fixing plate 23. A first rotating plate 252 is fixedly connected to the end of the telescopic rod 251 away from the disc body 21. A first rotating seat 253 is rotatably connected to the side of the first rotating plate 252 away from the telescopic rod 251 via a rotating rod. A placement frame 254 is fixedly connected to the side of the first rotating seat 253 away from the first rotating plate 252. A second rotating seat 255 is fixedly connected to the end of the placement frame 254 near the rotating column 22. A second rotating plate 256 is rotatably connected to the inner wall of the second rotating seat 255 via a rotating rod, and the end of the second rotating plate 256 away from the second rotating seat 255 is fixedly connected to the outer surface of the rotating column 22. After the CD detector 24 detects solar cells with color differences or damage, it operates the corresponding telescopic rod 251 to retract, causing the placement frame 254 to rotate around the second rotating plate 256 as a fulcrum. The placement frame 254 gradually changes from tilting upwards to tilting downwards. At the same time, the defective solar cells slide out from inside the placement frame 254 into the first collection tank 261. The placement frame 254 containing intact solar cells continues to rotate, and similarly, the intact solar cells are placed into the second collection tank 262, separating the superior and inferior products. This process also prevents the inspected solar cells from coming into contact with the operators, causing contamination or even damage, and ensures that the selected intact solar cells are not contaminated after sorting.

[0032] The placement frame 254 has several rollers 258 inside, and both ends of the rollers 258 are rotatably connected to the inner wall of the placement frame 254. The placement frame 254 is equipped with a limiting component 257. When the solar cell is placed inside the placement frame 254, it slides downward under the action of gravity. The rollers 258 rotate, and finally the solar cell is limited and locked by the limiting component 257. By setting the rollers 258, damage caused by sliding friction inside the placement frame 254 is avoided. At the same time, the rolling resistance of the rollers 258 is smaller, and they can smoothly reach the limiting component 257 for limiting, so that they can be detected by the CCD detector 24 in a fixed position, thereby improving the detection effect.

[0033] The limiting component 257 includes a limiting plate 2571, which is symmetrically arranged inside the placement frame 254 and fixedly connected to the inner wall of the placement frame 254. Several limiting blocks 2572 are provided on the side of the two limiting plates 2571 that are close to each other, and the limiting blocks 2572 are fixedly connected to the inner wall of the limiting plate 2571. When the solar cell contacts the limiting blocks 2572 on both sides, the limiting plate 2571 deforms slightly to lock the solar cell in place, thereby limiting the position of the solar cell. This makes the positions of the solar cells to be tested approximately the same, which is convenient for the CCD detector 24 to take pictures and detect, reduces the operation of adjusting the CCD detector 24 to align with the item to be tested, and saves manual operation.

[0034] A spring plate 2574 is symmetrically arranged on the side of the limiting plate 2571 away from the limiting block 2572. Both ends of the spring plate 2574 are fixedly connected to the outer surface of the limiting plate 2571, and the side of the spring plate 2574 away from the limiting plate 2571 is fixedly connected to the inner wall of the placement frame 254. A deformation groove 2573 is formed on the surface of the spring plate 2574 near the telescopic rod 251, and the deformation groove 2573 is formed on the side of the spring plate 2574 near the limiting plate 2571. Under the elastic force of the spring plate 2574... The spring plate 2574 supports the limiting plate 2571 to prevent the limiting plate 2571 from deforming too much and squeezing the solar cell, which would cause damage to the solar cell. At the same time, the surface of the spring plate 2574 near the telescopic rod 251 is provided with a deformation groove 2573, which makes the spring plate 2574 more likely to deform. Under the pressure of the solar cell, the spring plate 2574 deforms, so that the limiting block 2572 slightly clamps the solar cell and limits it without damaging the solar cell.

[0035] A sliding rod 2575 is fixedly connected to the side of the limiting plate 2571 away from the limiting block 2572, and the sliding rod 2575 is located at the interval between the two spring plates 2574. The end of the sliding rod 2575 away from the limiting plate 2571 passes through the placement frame 254 and slides inside it. The end of the sliding rod 2575 located outside the placement frame 254 is fixedly connected to an adapter plate 2576. An adapter block 2577 is fixedly connected to the side of the disc body 21 near the adapter plate 2576, and the adapter block 2577 is connected to the adapter plate 2576. The adapter plates 2576 cooperate with each other. As the placement frame 254 gradually changes from tilting upward to tilting downward, the adapter block 2577 and the adapter plate 2576 gradually cooperate. The two adapter plates 2576 move away from each other, causing the two slide rods 2575 to move away from each other, and further causing the two limiting plates 2571 to move away from each other. The limiting component 257 releases the solar cell, and the solar cell slides out of the placement frame 254, preventing the solar cell from getting stuck inside the placement frame 254 and causing the device to be blocked and affecting its use.

[0036] The separating component 26 includes a first collection tank 261, with connecting blocks 263 fixedly connected to both ends of the first collection tank 261. A second collection tank 262 is provided on the side of the connecting blocks 263 away from the first collection tank 261, and the two ends of the second collection tank 262 are fixedly connected to the outer surfaces of the two connecting blocks 263 respectively. Connecting plates 264 are fixedly connected to the sides of the first collection tank 261 and the second collection tank 262 near the rotating column 22, and the connecting plates 264 are fixedly connected to the outer surface of the rotating column 22. Plastic baffles 265 are fixedly connected to the sides of the first collection tank 261 and the second collection tank 262 near the disc body 21. By manipulating different telescopic rods 251, according to the detection results of the CCD detector 24, superior and inferior products are respectively placed into the first collection tank 261 and the second collection tank 262 to achieve the sorting operation. At the same time, by setting the plastic baffles 265, the solar cells are prevented from being ejected due to vibration and damaged.

[0037] The inner walls of the first collection tank 261 and the second collection tank 262 are slidably connected to a slide plate 266, and the middle part of the slide plate 266 protrudes upward. The inner walls of the first collection tank 261 and the second collection tank 262 are fixedly connected to a spring 267. The side of the slide plate 266 away from the plastic baffle 265 is fixedly connected to the spring 267. When the solar cell falls into the surface of the slide plate 266, due to the upward protrusion of the middle part of the slide plate 266, the solar cell slides downward a distance on the surface of the slide plate 266. As the solar cell continues to fall in, the spring 267 is compressed and rebounds, generating vibration. The previous solar cell continues to slide downward due to the vibration, thereby gradually arranging the solar cells on the surface of the slide plate 266, avoiding the accumulation and blockage of the solar cells on the surface of the slide plate 266.

[0038] In use, the solar cell is placed inside the placement frame 254 and slides downwards under gravity. The roller 258 rotates, and eventually the solar cell is locked in place by the limiting component 257. Then, the motor 32 is started, and the output end of the motor 32 rotates, driving the rotating shaft 33 to rotate. The rotating shaft 33 drives the driving gear 34 to rotate, which in turn drives the driven gear 35 to rotate. By setting an incomplete gear structure for the driving gear 34, the driving gear 34 intermittently meshes with the driven gear 35. The intermittent rotation of the driven gear 35 drives the rotating column 22 to rotate intermittently, which in turn drives the disk 21 to rotate intermittently. This causes the solar panel to rotate intermittently with the placement component 25. The CCD detector 24 captures images to detect solar cells with color differences or damage. The corresponding telescopic rod 251 is retracted, causing the placement frame 254 to rotate around the second rotating plate 256. The placement frame 254 gradually changes from an upward tilt to a downward tilt. At the same time, the defective solar cells slide out from the placement frame 254 into the first collection groove 261. The placement frame 254 containing the intact solar cells continues to rotate, and the intact solar cells are similarly placed into the second collection groove 262. The solar cells fall onto the surface of the slide plate 266. Since the middle of the slide plate 266 is raised upward, the solar cells slide down a certain distance on the surface of the slide plate 266. The solar cells continue to fall in, and the spring 267 is compressed and rebounds, generating vibration. The previous solar cell continues to slide down due to the vibration, thereby gradually arranging the solar cells onto the surface of the slide plate 266.
