Description

Technical Field

[0001] This invention relates to the field of silicon wafer batteries, specifically to a silicon wafer battery sorting and transmission device and a sorting and transmission method thereof. Background Technology

[0002] Silicon wafer solar cells are photovoltaic cells made primarily from high-purity monocrystalline or polycrystalline silicon materials.

[0003] Its core principle is based on the potential difference of the PN junction in semiconductor materials and the photovoltaic effect, converting solar energy into electrical energy. Silicon wafers are the main raw material for photovoltaic cells, accounting for 74%-75% of the total cost of the cell. Depending on the doping elements, silicon wafers can be divided into P-type and N-type semiconductors, which are then combined into cells capable of generating electricity.

[0004] After the silicon wafers are produced, they need to be inspected and sorted. During inspection, vision sensors are generally used to detect whether the silicon wafers have cracks. The silicon wafers with cracks are classified according to the size and number of cracks, and then placed on the corresponding transmission line according to the classification results to complete the sorting and transmission work.

[0005] Currently, sorting and conveying equipment classifies silicon wafers based on vision sensors and then uses suction cups to pick them up and place them on the corresponding conveyor line. However, the suction cups used in current sorting and conveying equipment are all fixed models that are fixed to the equipment. Since sorting and conveying equipment generally needs to sort multiple models of silicon wafers, if multiple models of silicon wafers are picked up by the same suction cup, the silicon wafers are prone to falling off when the equipment is moved to a different conveyor line, which affects the sorting process. Summary of the Invention

[0006] Objective of the invention: To provide a silicon wafer battery sorting and transmission device and a sorting and transmission method thereof to solve the above-mentioned problems existing in the prior art.

[0007] Technical solution: A silicon wafer battery sorting and transmission device, comprising:

[0008] A transmission unit, a positioning unit located above the transmission unit, and a sorting unit connected to the positioning unit;

[0009] The sorting section includes a lifting mechanism connected to the positioning section, and a suction mechanism connected to the lifting mechanism;

[0010] The bottom of the lifting mechanism is also provided with a limiting mechanism, which includes:

[0011] The linkage unit includes two sets of transmission wheels installed side by side at the end and bottom of the lifting mechanism, a transmission belt sleeved between the two sets of transmission wheels, and a switching component connected to the lifting mechanism and abutting against the transmission belt.

[0012] The transmission unit includes a transmission component connected to the bottom drive wheel, and an adjustment component abutting against the transmission component;

[0013] The limit bracket is connected to the transmission component.

[0014] This invention designs a limiting mechanism at the bottom of the lifting mechanism. By linking the lifting mechanism with a switching component, the limiting frame swings, thereby supporting the silicon wafer battery adsorbed by the suction mechanism, thus avoiding abnormal falling of the silicon wafer battery when it moves to the sorting and transmission line.

[0015] Meanwhile, this application also includes a speed-changing unit. Through the design of the speed-changing unit, the swing speed of the limit frame can be controlled, and the swing speed of the limit frame can be controlled according to the requirements.

[0016] In a further embodiment, the adjusting unit includes:

[0017] The longitudinal module includes an adjustment frame, a longitudinal slide rail and a longitudinal rack mounted on the adjustment frame;

[0018] The longitudinal slide rail is equipped with a longitudinal slider;

[0019] A longitudinal drive member is engaged on the longitudinal rack, and the longitudinal drive member includes:

[0020] Longitudinal motor;

[0021] A longitudinal rotating shaft, on which a longitudinal wheel is sleeved and connected to the output end of the longitudinal motor, and at the end of which a longitudinal gear is sleeved and meshes with the longitudinal rack;

[0022] The transverse module includes a transverse frame connected to the longitudinal slider, a transverse slide rail and a transverse motor mounted on the transverse frame, a transverse lead screw connected to the output end of the transverse motor, and a transverse slider sleeved on the transverse lead screw and adapted to the transverse slide rail.

[0023] The longitudinal motor is fixedly installed on the side of the transverse frame, and a longitudinal sliding sleeve sleeved on the longitudinal shaft is also installed on the side of the transverse frame.

[0024] By designing an adjustment section, silicon wafer cells are moved from the feeding conveyor line to the sorting conveyor line.

[0025] In a further embodiment, the lifting mechanism includes:

[0026] The cavity is composed of a lifting frame and a lifting cover, and there is a predetermined gap between the lifting frame and the lifting cover;

[0027] A lifting motor is installed at the end of the lifting frame. The output end of the lifting motor is connected to a lifting screw located inside the lifting frame. A lifting sleeve is fitted on the lifting screw.

[0028] A lifting slide rail is installed inside the lifting frame, and a lifting slider is adapted on the lifting slide rail;

[0029] The lifting block is connected to the lifting sleeve and the lifting slider, and extends a predetermined portion to the outside of the lifting frame and the lifting cover.

[0030] In a further embodiment, the suction mechanism includes:

[0031] The suction rack is connected to the lifting block;

[0032] The adjustment unit includes a suction main frame connected to the suction frame, a suction fixing plate mounted on the suction main frame, an adjustment motor connected to the suction fixing plate, an adjustment disk disposed at the output end of the adjustment motor, and four sets of movable parts hinged to the adjustment disk and mounted in a cross direction.

[0033] The suction cup unit includes a fixed suction cup component connected to the suction fixing plate, and four sets of movable suction cup components connected to four sets of movable components respectively.

[0034] By designing an adjustment unit, the adsorption position of the movable suction cup can be adjusted. This allows for the selection of a suitable edge suction position based on the size of the silicon wafer, preventing the suction position from being too close to the center when the silicon wafer is large. This avoids the adsorption point of the silicon wafer being too concentrated and alleviates the situation of abnormal falling to a certain extent.

[0035] In a further embodiment, each set of moving parts includes:

[0036] The sliding components are designed in two sets, which are installed on the upper and lower sides of the suction main frame respectively. Each set includes an adjusting slider connected to the suction main frame and an adjusting slider adapted to the adjusting slide rail.

[0037] The adjustment frame is connected to the adjustment slider installed on the upper side of the suction main frame;

[0038] The hinge rod is hinged at one end to the adjustment frame and at the other end to the adjustment disc;

[0039] The fixed suction cup components include:

[0040] A fixed lifting cylinder is connected to a suction fixing plate;

[0041] A fixed plate frame is installed at the output end of a fixed lifting cylinder, and multiple sets of fixed suction cups are installed at the bottom of the fixed plate frame;

[0042] Each set of movable suction cup components includes:

[0043] A movable connecting frame is connected to an adjusting slider installed on the lower side of the suction main frame, and a movable lifting cylinder is installed on the movable connecting frame;

[0044] The movable plate frame is located below the movable connecting frame and is connected to the output end of the movable lifting cylinder. The bottom of the movable plate frame is equipped with multiple sets of movable suction cups, and the top is provided with a movable rod that is inserted into the movable connecting frame.

[0045] In a further embodiment, the switching element includes two sets of switching units respectively abutting the side away from the drive belt, each set of switching units including:

[0046] A switching cylinder, wherein the output end of the switching cylinder is provided with a switching pressure plate, and the switching pressure plate abuts against the transmission belt;

[0047] The switching frame is mounted on the switching cylinder and close to the output end;

[0048] One set of switching unit switching cylinders is connected to the lifting block, and another set of switching unit switching cylinders is installed in the lifting frame body;

[0049] The swing and hovering of the limit frame can be controlled by the design of the switching component;

[0050] Independent control of hovering and swinging allows the silicon wafer to be re-adsorbed even when it falls onto the limit frame, through the lifting mechanism or the fixed lifting cylinder and the movable lifting cylinder.

[0051] In a further embodiment, the transmission component includes two sets of parallel transmission units and a transmission belt sleeved on the two sets of transmission units;

[0052] Each transmission unit includes:

[0053] A speed-changing shaft is inserted into the lifting frame. A fixed wheel is installed on the speed-changing shaft. A through cavity is opened inside the speed-changing shaft. A shaft spring is provided inside the through cavity. A shaft stop is provided at the end of the shaft spring. A shaft groove communicating with the through cavity is opened on the surface of the speed-changing shaft.

[0054] The design of the pivot spring allows the gear shift wheel to move away from the fixed wheel when there is no obstruction.

[0055] A gear shift sleeve is fitted on the gear shift shaft and extends through the shaft groove into the through cavity to connect with the shaft stop block. A gear shift wheel is installed on the gear shift sleeve.

[0056] The design of the gear shift sleeve, shaft stop block and shaft groove enables the rotation of the gear shift shaft to drive the gear shift wheel to rotate, and the distance between the gear shift wheel and the fixed wheel can be changed during the rotation.

[0057] The fixed wheel and the variable wheel are conical wheels arranged opposite each other;

[0058] The inner side of the speed belt is provided with a tapered step that is adapted to the tapered wheel;

[0059] The fixed pulley and the variable pulley are designed as conical pulleys, and a conical step is designed on the inner side of the variable belt. This is mainly so that when the distance between the variable pulley and the fixed pulley changes, the variable belt can adapt to the change in distance, thereby changing the rotation diameter, changing the transmission ratio at both ends, and completing the motion of acceleration, constant speed, and deceleration.

[0060] The gear shift shaft of one gear shift unit is connected to the bottom drive wheel, and the gear shift shaft of the other gear shift unit extends to the outside of the lifting frame and is connected to the limit frame.

[0061] The drive wheel is installed inside the lifting frame.

[0062] The swing speed of the limit frame is controlled by designing a speed-changing unit;

[0063] In a further embodiment, the adjusting member includes:

[0064] The regulating cylinder is hinged within the lifting frame body;

[0065] An adjusting column is installed inside the lifting frame body;

[0066] An adjusting rod is hinged in the middle to the adjusting column, one end of the adjusting rod is hinged to the output end of the adjusting cylinder, and both ends of the adjusting rod are provided with adjusting balls that abut against the gear shift wheel;

[0067] The linkage-type adjustment mechanism ensures that the two sets of transmission units have the same stroke during operation, avoiding the situation where the transmission belt is too tight or too loose when the stroke of the transmission pulley and the fixed pulley of the two sets of transmission units is inconsistent.

[0068] In a further embodiment, the transmission unit includes a feeding transmission line and a multi-group sorting transmission line. The feeding transmission line and the multi-group sorting transmission line are transmission modules with the same structure, including a fixed frame, a transmission frame mounted on the fixed frame, transmission shafts disposed at both ends of the transmission frame, and a transmission belt sleeved on the transmission shaft.

[0069] A transmission motor is installed on the side of the transmission frame, and the output end of the transmission motor is connected to any set of transmission shafts.

[0070] The feeding conveyor line is equipped with a detection frame connected to the conveyor frame, and a vision sensor is installed at the bottom of the detection frame.

[0071] A sorting and conveying method for a silicon wafer battery sorting and conveying device includes:

[0072] Step 1: The silicon wafer cells on the feeding conveyor line are inspected and classified. Based on the classification results, the adjustment unit and the sorting unit work to sort the silicon wafer cells to the corresponding sorting conveyor line.

[0073] During operation, silicon wafers are placed on the feeding conveyor line, which drives the silicon wafers to move. The silicon wafers are detected by a vision sensor, and classified based on the detection results. After classification, the silicon wafers are sorted to the corresponding sorting conveyor line by the working of the adjustment unit and the sorting unit, and then transported to the next station.

[0074] When the positioning unit is working, the vertical module and the horizontal module work together to move the sorting unit to above the silicon wafer cells after inspection;

[0075] Step 2: When the sorting unit is working, the lifting mechanism drives the suction mechanism to move to the predetermined position, and then the suction mechanism picks up the silicon wafer. After the silicon wafer is picked up, the limiting mechanism supports the silicon wafer, and the adjusting part drives the silicon wafer to move to the sorting and transmission line to complete the sorting and transmission work.

[0076] Step 21: When the suction mechanism is working, the fixed lifting cylinder drives the fixed plate frame to descend, so that the fixed suction cup contacts the silicon wafer cell. Then, the movable lifting cylinder drives the movable plate frame to descend, so that the movable suction cup contacts the silicon wafer cell. The movable suction cup adsorbs the edge of the silicon wafer cell, thus completing the adsorption.

[0077] Before adsorption, the position of the movable suction cup is adjusted by the adjustment unit to change the adsorption position of the movable suction cup. During adjustment, the adjustment motor drives the adjustment plate to rotate, which drives the adjustment rod to move, which drives the adjustment frame to move along the adjustment slide rail, which in turn drives the adjustment frame to move, which in turn drives the movable plate frame to move, which in turn drives the movable suction cup to move, thus changing the adsorption position of the movable suction cup.

[0078] Step 22: After the silicon wafer cell is adsorbed, the lifting mechanism drives the suction mechanism to move a predetermined distance, and the limiting frame of the limiting mechanism holds the silicon wafer cell.

[0079] The swing and hovering of the limit frame are controlled by the operation of the switching unit. When swinging, one set of switching units works to link the lifting block and the transmission belt. When hovering, one set of switching units resets and the other set of switching units works to limit the movement of the transmission belt.

[0080] Step 23: After the silicon wafer cell is adsorbed, the speed change unit works. The transmission wheel drives one set of speed change units to rotate, which drives the speed change belt to move, which drives another set of speed change units to rotate, which drives the limit frame to swing.

[0081] The distance between the fixed pulley and the variable pulley of the two sets of speed change units is adjusted by adjusting the adjustment components, thereby adjusting the transmission diameter at both ends of the speed change belt, changing the transmission ratio, completing the speed change operation, and changing the swing speed of the limit frame.

[0082] Beneficial effects: This invention discloses a silicon wafer battery sorting and transmission device and its sorting and transmission method. This invention designs a limiting mechanism at the bottom of the lifting mechanism, and drives the limiting frame to swing by a switching component to support the silicon wafer battery adsorbed by the suction mechanism, thereby avoiding abnormal falling of the silicon wafer battery when it moves to the sorting and transmission line.

[0083] Meanwhile, this application also includes a speed-changing unit. Through the design of the speed-changing unit, the swing speed of the limit frame can be controlled, and the swing speed of the limit frame can be controlled according to the requirements. Attached Figure Description

[0166] The gear shift sleeve 2242 is sleeved on the gear shift shaft 2241 and extends through the shaft groove 2241A into the through cavity to connect with the shaft stop block 2241B. The gear shift sleeve 2242 is equipped with a gear shift wheel 2243.

[0167] The design of the transmission sleeve 2242, the shaft stop block 2241B and the shaft groove 2241A enables the rotation of the transmission shaft 2241 to drive the transmission wheel 2243 to rotate, and the distance between the transmission wheel 2243 and the fixed wheel 2244 can be changed during the rotation.

[0168] The fixed wheel 2244 and the variable wheel 2243 are conical wheels arranged opposite to each other;

[0169] The inner side of the speed belt 2245 is provided with a tapered step 2245A that is adapted to the tapered pulley;

[0170] The fixed pulley 2244 and the variable pulley 2243 are designed as conical pulleys, and a conical step 2245A is designed on the inner side of the variable belt 2245. This is mainly so that when the distance between the variable pulley 2243 and the fixed pulley 2244 changes, the variable belt 2245 can adapt to the changed distance, thereby changing the rotation diameter, changing the transmission ratio at both ends, and completing the motion of acceleration, constant speed, and deceleration.

[0171] The gear shift shaft 2241 of one gear shift unit 224 is connected to the bottom drive wheel 221, and the gear shift shaft 2241 of another gear shift unit 224 extends to the outside of the lifting frame 211 and is connected to the limit frame 225.

[0172] The drive wheel 221 is installed inside the lifting frame 211.

[0173] The swing speed of the limit frame 225 is controlled by designing a speed change unit 224;

[0174] The adjusting element includes:

[0175] Adjusting cylinder 2246 is hinged inside lifting frame 211;

[0176] Adjustment column 2247 is installed inside the lifting frame 211;

[0177] The adjusting rod 2248 is hinged in the middle to the adjusting column 2247. One end of the adjusting rod 2248 is hinged to the output end of the adjusting cylinder 2246. Both ends of the adjusting rod 2248 are provided with adjusting balls that abut against the speed change wheel 2243.

[0178] The linkage-type adjustment component design ensures that the two sets of transmission units 224 have the same stroke when working, avoiding the situation where the transmission belt 2245 is too tight or too loose when the transmission pulley 2243 and the fixed pulley 2244 of the two sets of transmission units 224 have different strokes.

[0179] A sorting and conveying method for a silicon wafer battery sorting and conveying device includes:

[0180] Step 1: The silicon wafer cells on the feeding conveyor line 3 are detected and classified. Based on the classification results, the positioning unit 1 and the sorting unit 2 work to sort the silicon wafer cells onto the corresponding sorting conveyor line 4.

[0181] During operation, the silicon wafer cells are placed on the feeding conveyor line 3, which drives the silicon wafer cells to move. The silicon wafer cells are detected by a vision sensor, and they are classified based on the detection results. After classification, the silicon wafer cells are sorted into the corresponding sorting conveyor line 4 by the working of the positioning unit 1 and the sorting unit 2, and then transported to the next station.

[0182] During inspection, visual sensors are used to determine whether there are cracks in the silicon wafer. The classification is based on the size and location of the cracks, and the classification criteria can be customized according to the actual situation or manufacturing requirements.

[0183] When the sorting conveyor line 4 and the feeding conveyor line 3 are working, the conveyor motor 45 drives the conveyor shaft 43 to rotate, which in turn drives the conveyor belt 44 to move, thus completing the conveying work.

[0184] When the positioning unit 1 is working, the vertical module and the horizontal module 13 work together to drive the sorting unit 2 to move above the silicon wafer cell after inspection.

[0185] When the longitudinal module is working, the longitudinal motor 124 drives the longitudinal wheel to rotate, which in turn drives the longitudinal shaft 125 to rotate, which in turn drives the longitudinal gear 126 to rotate, which in turn drives the transverse frame 131 to move along the longitudinal slide rail 121.

[0186] When the horizontal module 13 is working, the horizontal motor 133 drives the horizontal lead screw 134 to rotate, which drives the horizontal slider 135 to move along the horizontal slide rail 132, thereby driving the sorting section 2 to move to the predetermined position.

[0187] Step 2: When the sorting unit 2 is working, the lifting mechanism 21 drives the suction mechanism 23 to move to the predetermined position, and the suction mechanism 23 sucks up the silicon wafer cell. After the silicon wafer cell is sucked up, the limiting mechanism 22 supports the silicon wafer cell, and the positioning unit 1 drives the silicon wafer cell to move onto the sorting and transmission line 4 to complete the sorting and transmission work.

[0188] When the lifting mechanism 21 is working, the lifting motor 213 drives the lifting screw 214 to rotate, which in turn drives the lifting block 216 to move along the lifting slide rail 215, and drives the suction mechanism 23 to move to the predetermined position.

[0189] Step 21: When the suction mechanism 23 is working, the fixed lifting cylinder 2333 drives the fixed plate frame 2331 to descend, so that the fixed suction cup 2332 contacts the silicon wafer cell. Then, the movable lifting cylinder 2338 drives the movable plate frame 2334 to descend, so that the movable suction cup 2335 contacts the silicon wafer cell. The movable suction cup 2335 adsorbs the edge of the silicon wafer cell, thus completing the adsorption.

[0190] Before adsorption, the position of the movable suction cup 2335 is adjusted by the adjustment unit to change the adsorption position of the movable suction cup 2335. During adjustment, the adjustment motor drives the adjustment disk 2323 to rotate, which drives the adjustment rod 2248 to move, which drives the adjustment frame 2326 to move along the adjustment slide rail 2324. The adjustment frame 2326 moves, which drives the movable disk frame 2334 to move, which drives the movable suction cup 2335 to move, thus changing the adsorption position of the movable suction cup 2335.

[0191] Step 22: After the silicon wafer cell is adsorbed, the lifting mechanism 21 drives the suction mechanism 23 to move a predetermined distance, and the limiting frame 225 of the limiting mechanism 22 holds the silicon wafer cell.

[0192] The operation of the switching unit 223 controls the swing and hovering of the limit frame 225. When swinging, a set of switching units works to link the lifting block 216 and the transmission belt 222. When hovering, a set of switching units resets and another set of switching units works to restrict the movement of the transmission belt 222.

[0193] When the lifting block 216 and the transmission belt 222 are linked, the switching cylinder 223A drives the switching plate 223C to move, so that the switching plate 223C abuts against the transmission belt 222, and the transmission belt 222 is clamped between the switching plate 223C and the switching frame 223B. At this time, when the lifting block 216 moves, it will drive the transmission belt 222 to move, drive the transmission wheel 221 to move, drive the speed change unit 224 to move, and drive the limit frame 225 to swing. At this time, the speed change unit 224 controls the swing speed of the limit frame 225 until the limit frame 225 supports the silicon wafer cell.

[0194] When hovering, one set of switching units resets, and another set of switching units works. The switching cylinder 223A drives the switching plate 223C to move, so that the switching plate 223C abuts against the transmission belt 222, clamping the transmission belt 222 between the switching plate 223C and the switching frame 223B, thus limiting the transmission belt 222 and thereby completing the hovering of the limiting frame 225.

[0195] Step 23: After the silicon wafer cell is adsorbed, the speed change unit 224 works. The transmission wheel 221 drives one set of speed change units 224 to rotate, which drives the speed change belt 2245 to move, which drives another set of speed change units 224 to rotate, which drives the limit frame 225 to swing.

[0196] The distance between the fixed wheel 2244 and the variable wheel 2243 of the two sets of speed change units 224 is adjusted by adjusting the adjustment component, the transmission diameter at both ends of the speed change belt 2245 is adjusted, the transmission ratio is changed, the speed change is completed, and the swing speed of the limit frame 225 is changed.

[0197] When the swing speed of the limit frame 225 is increased, the adjusting cylinder 2246 drives the adjusting rod 2248 to swing, causing the adjusting ball at one end of the adjusting rod 2248 to abut against the gear shift wheel 2243 of the gear shift unit 224, bringing it closer to the fixed wheel 2244 of the gear shift unit 224. The distance between the gear shift wheel 2243 and the fixed wheel 2244 of the gear shift unit 224 decreases, compressing the conical step 2245A of the gear shift belt 2245, causing the gear shift belt 2245 at the gear shift unit 224 to move straight. As the diameter increases, the adjusting ball at the other end of the adjusting rod 2248 will stop contacting the gear wheel 2243 of the other gear unit 224. The gear wheel 2243 of the other gear unit 224 will move away from the fixed wheel 2244 of the other gear unit 224. At this time, the distance between the gear wheel 2243 and the fixed wheel 2244 of the other gear unit 224 will increase, thereby reducing the movement diameter of the gear belt 2245 at the other gear unit 224, thus completing the acceleration transmission and increasing the swing speed of the limit frame 225.

[0198] When the swing speed of the limit frame 225 is reduced, the adjusting cylinder 2246 drives the adjusting rod 2248 to swing, causing the adjusting ball at the other end of the adjusting rod 2248 to abut against the gear shift wheel 2243 of another gear shift unit 224, bringing it closer to the fixed wheel 2244 of the other gear shift unit 224. The distance between the gear shift wheel 2243 and the fixed wheel 2244 of the other gear shift unit 224 decreases, compressing the conical step 2245A of the gear shift belt 2245, causing the gear shift belt 2245 at the other gear shift unit 224 to... As the movement diameter of 245 increases, the adjusting ball at one end of the adjusting rod 2248 will stop contacting the gear shift wheel 2243 of the gear shift unit 224. The gear shift wheel 2243 of the gear shift unit 224 will move away from the fixed wheel 2244 of the gear shift unit 224. At this time, the distance between the gear shift wheel 2243 and the fixed wheel 2244 of the gear shift unit 224 increases, which reduces the movement diameter of the gear shift belt 2245 at the gear shift unit 224, thereby completing the deceleration transmission and reducing the swing speed of the limit frame 225.

[0199] Working principle explanation:

[0200] The silicon wafer cells are placed on the feeding conveyor line 3, which drives the silicon wafer cells to move. The silicon wafer cells are detected by a vision sensor, and they are classified based on the detection results. After classification, the silicon wafer cells are sorted into the corresponding sorting conveyor line 4 by the working of the positioning unit 1 and the sorting unit 2, and then transported to the next station.

[0201] During inspection, visual sensors are used to determine whether there are cracks in the silicon wafer. The classification is based on the size and location of the cracks, and the classification criteria can be customized according to the actual situation or manufacturing requirements.

[0202] When the sorting conveyor line 4 and the feeding conveyor line 3 are working, the conveyor motor 45 drives the conveyor shaft 43 to rotate, which in turn drives the conveyor belt 44 to move, thus completing the conveying work.

[0203] When the positioning unit 1 is working, the vertical module and the horizontal module 13 work together to drive the sorting unit 2 to move above the silicon wafer cell after inspection.

[0204] When the longitudinal module is working, the longitudinal motor 124 drives the longitudinal wheel to rotate, which in turn drives the longitudinal shaft 125 to rotate, which in turn drives the longitudinal gear 126 to rotate, which in turn drives the transverse frame 131 to move along the longitudinal slide rail 121.

[0205] When the horizontal module 13 is working, the horizontal motor 133 drives the horizontal lead screw 134 to rotate, which drives the horizontal slider 135 to move along the horizontal slide rail 132, thereby driving the sorting section 2 to move to the predetermined position.

[0206] When the sorting unit 2 is working, the lifting mechanism 21 drives the suction mechanism 23 to move to the predetermined position, and then the suction mechanism 23 picks up the silicon wafer cell. After the silicon wafer cell is picked up, the limiting mechanism 22 supports the silicon wafer cell, and the adjusting unit 1 drives the silicon wafer cell to move onto the sorting and transmission line 4 to complete the sorting and transmission work.

[0207] When the lifting mechanism 21 is working, the lifting motor 213 drives the lifting screw 214 to rotate, which in turn drives the lifting block 216 to move along the lifting slide rail 215, and drives the suction mechanism 23 to move to the predetermined position.

[0208] When the suction mechanism 23 is working, the fixed lifting cylinder 2333 drives the fixed plate frame 2331 to descend, so that the fixed suction cup 2332 contacts the silicon wafer cell. Then, the movable lifting cylinder 2338 drives the movable plate frame 2334 to descend, so that the movable suction cup 2335 contacts the silicon wafer cell. The movable suction cup 2335 adsorbs the edge of the silicon wafer cell, thus completing the adsorption.

[0209] Before adsorption, the position of the movable suction cup 2335 is adjusted by the adjustment unit to change the adsorption position of the movable suction cup 2335. During adjustment, the adjustment motor drives the adjustment disk 2323 to rotate, which drives the adjustment rod 2248 to move, which drives the adjustment frame 2326 to move along the adjustment slide rail 2324. The adjustment frame 2326 moves, which drives the movable disk frame 2334 to move, which drives the movable suction cup 2335 to move, thus changing the adsorption position of the movable suction cup 2335.

[0210] After the silicon wafer cell is adsorbed, the lifting mechanism 21 drives the suction mechanism 23 to move a predetermined distance, and the limiting frame 225 of the limiting mechanism 22 holds the silicon wafer cell.

[0211] The operation of the switching unit 223 controls the swing and hovering of the limit frame 225. When swinging, a set of switching units works to link the lifting block 216 and the transmission belt 222. When hovering, a set of switching units resets and another set of switching units works to restrict the movement of the transmission belt 222.

[0212] When the lifting block 216 and the transmission belt 222 are linked, the switching cylinder 223A drives the switching plate 223C to move, so that the switching plate 223C abuts against the transmission belt 222, and the transmission belt 222 is clamped between the switching plate 223C and the switching frame 223B. At this time, when the lifting block 216 moves, it will drive the transmission belt 222 to move, drive the transmission wheel 221 to move, drive the speed change unit 224 to move, and drive the limit frame 225 to swing. At this time, the speed change unit 224 controls the swing speed of the limit frame 225 until the limit frame 225 supports the silicon wafer cell.

[0213] When hovering, one set of switching units resets, and another set of switching units works. The switching cylinder 223A drives the switching plate 223C to move, so that the switching plate 223C abuts against the transmission belt 222, clamping the transmission belt 222 between the switching plate 223C and the switching frame 223B, thus limiting the transmission belt 222 and thereby completing the hovering of the limiting frame 225.

[0214] When the speed change unit 224 is working, the transmission wheel 221 drives one set of speed change units 224 to rotate, which drives the speed change belt 2245 to move, drives another set of speed change units 224 to rotate, and drives the limit frame 225 to swing.

[0215] The distance between the fixed wheel 2244 and the variable wheel 2243 of the two sets of speed change units 224 is adjusted by adjusting the adjustment component, the transmission diameter at both ends of the speed change belt 2245 is adjusted, the transmission ratio is changed, the speed change is completed, and the swing speed of the limit frame 225 is changed.

[0216] When the swing speed of the limit frame 225 is increased, the adjusting cylinder 2246 drives the adjusting rod 2248 to swing, causing the adjusting ball at one end of the adjusting rod 2248 to abut against the gear shift wheel 2243 of the gear shift unit 224, bringing it closer to the fixed wheel 2244 of the gear shift unit 224. The distance between the gear shift wheel 2243 and the fixed wheel 2244 of the gear shift unit 224 decreases, compressing the conical step 2245A of the gear shift belt 2245, causing the gear shift belt 2245 at the gear shift unit 224 to move straight. As the diameter increases, the adjusting ball at the other end of the adjusting rod 2248 will stop contacting the gear wheel 2243 of the other gear unit 224. The gear wheel 2243 of the other gear unit 224 will move away from the fixed wheel 2244 of the other gear unit 224. At this time, the distance between the gear wheel 2243 and the fixed wheel 2244 of the other gear unit 224 will increase, thereby reducing the movement diameter of the gear belt 2245 at the other gear unit 224, thus completing the acceleration transmission and increasing the swing speed of the limit frame 225.

[0217] When the swing speed of the limit frame 225 is reduced, the adjusting cylinder 2246 drives the adjusting rod 2248 to swing, causing the adjusting ball at the other end of the adjusting rod 2248 to abut against the gear shift wheel 2243 of another gear shift unit 224, bringing it closer to the fixed wheel 2244 of the other gear shift unit 224. The distance between the gear shift wheel 2243 and the fixed wheel 2244 of the other gear shift unit 224 decreases, compressing the conical step 2245A of the gear shift belt 2245, causing the gear shift belt 2245 at the other gear shift unit 224 to... As the movement diameter of 245 increases, the adjusting ball at one end of the adjusting rod 2248 will stop contacting the gear shift wheel 2243 of the gear shift unit 224. The gear shift wheel 2243 of the gear shift unit 224 will move away from the fixed wheel 2244 of the gear shift unit 224. At this time, the distance between the gear shift wheel 2243 and the fixed wheel 2244 of the gear shift unit 224 increases, which reduces the movement diameter of the gear shift belt 2245 at the gear shift unit 224, thereby completing the deceleration transmission and reducing the swing speed of the limit frame 225.

The distance between the fixed wheel (2244) and the speed change wheel (2243) of the two speed change units (224) is adjusted by the adjustment component. The transmission diameter at both ends of the speed change belt (2245) is adjusted, the transmission ratio is changed, the speed change is completed, and the swing speed of the limit frame (225) is changed.
