Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a conveying and steering mechanism for processing crystalline silicon plates. Background Art

[0002] The conveying and steering mechanism for crystalline silicon panel processing is an automated equipment component used to adjust the transmission direction of crystalline silicon panels on the conveyor line. It is a key auxiliary equipment in the crystalline silicon panel manufacturing line. It can be used to connect different processing steps, ensure the efficient and smooth flow of crystalline silicon panels between various production links, and improve production continuity and automation level.

[0003] However, in actual use, when the existing conveying and steering mechanism drives the crystalline silicon plate to turn, the crystalline silicon plate is subjected to centrifugal force and slight lateral force during the turning, and the crystalline silicon plate may slip laterally, resulting in an angular deviation, which in turn causes its position to deviate from the preset trajectory when entering the next process, often requiring shutdown and adjustment, affecting production continuity.

[0004] In addition, during the turning process of the crystalline silicon plate, the four corners of the crystalline silicon plate are prone to collide and scratch with the hard parts of the conveying mechanism (such as metal baffles and the edge of the rotating shaft), resulting in hidden cracks, missing corners or edge breakage, which directly affects the product yield.

[0005] To this end, a conveying and steering mechanism for processing crystalline silicon plates is proposed. Summary of the Invention

[0006] The object of the present invention is to provide a conveying and steering mechanism for processing crystalline silicon plates to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a conveyor steering mechanism for processing crystalline silicon panels, comprising a conveyor base, a plurality of electric telescopic rods and a servo motor fixedly connected to the top surface of the conveyor base, a roller frame fixedly connected to the telescopic ends of the electric telescopic rods, a load-bearing roller rotatably connected to the roller frame, a steering plate fixedly connected to the output shaft of the servo motor, and a visual sensor fixedly connected to the conveyor base; A conveying protection assembly is provided on the conveyor base, and the conveying protection assembly includes four electric telescopic rods 2 slidingly arranged above the steering plate, a supporting plate fixedly connected to the telescopic end of each electric telescopic rod 2, two slides slidably connected to the supporting plate, a fixed plate 1 and a fixed plate 2 and an electric telescopic rod 3 fixedly connected to the supporting plate, a guide rod fixedly connected to the fixed plate 1 and the fixed plate 2, a spring connected between the slide and the fixed plate 2, a block fixedly connected to the bottom end of the slide, a rubber pad fixedly connected to the block, and a push rod fixedly connected to the telescopic end of the electric telescopic rod 3. A sliding groove is provided on the supporting plate at a position corresponding to the slide, and the slide is slidably connected in the sliding groove. The push rod can contact the slide, and the sliding paths of the two slides are perpendicular to each other.

[0008] Furthermore, the conveying protection assembly also includes two support plates symmetrically fixedly connected to the steering plate, a load-bearing rod fixedly connected to each support plate, and two sliding frames slidably connected to each load-bearing rod, and the electric telescopic rod 2 is installed and fixed at the bottom end of the sliding frame.

[0009] Furthermore, the top of each sliding frame is threadedly connected to a threaded rod, the bottom end of each threaded rod is fixedly connected to a friction pad, and the bottom end of the threaded rod and the friction pad are located in the sliding frame.

[0010] Furthermore, a rubber belt is fixedly connected between the two blocks on each supporting plate.

[0011] Furthermore, each carrying roller is fixedly connected to a plurality of rollers in a linear array, and all the carrying rollers are connected via a transmission device, which can drive the carrying rollers to rotate.

[0012] Furthermore, the transmission device includes a motor, a chain and a sprocket. Each load-bearing roller is fixedly connected to a sprocket. The chain connects all the sprockets. The motor is fixedly connected to one of the load-bearing rollers.

[0013] Furthermore, a plurality of grid holes are provided on the steering plate in a mesh shape, and the grid holes of the steering plate correspond to the positions of the rollers on the carrying roller.

[0014] Furthermore, the support plate is configured to be U-shaped.

[0015] Furthermore, the stop block, the rubber pad and the rubber belt are all located below the bearing plate.

[0016] Furthermore, the push rod is configured to be L-shaped, and both sides of the push rod are perpendicular to the two sliding grooves respectively.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The conveying protection assembly operates by placing inward-pushing rubber pads at the four corners of the crystalline silicon panel, which can form a stable constraint on the crystalline silicon panel from the four sides. This prevents the crystalline silicon panel from sliding laterally or shifting in angle, ensuring that it always maintains a stable posture and preset trajectory during the steering process, thus avoiding position deviation problems. Through the operation of the conveying protection component, a rubber belt is designed to wrap the four corners of the crystalline silicon panel. The rubber belt can serve as a buffer and isolation structure to prevent the four corners of the crystalline silicon panel from directly contacting other hard components, and to prevent relative displacement and collision between the crystalline silicon panel and other components; The operation of the conveying protection component can correct the crystalline silicon panels, adjusting the skewed crystalline silicon panels to the preset correct posture while turning. This ensures that they are accurately positioned when entering the next process, better aligning with the subsequent processing equipment, and avoiding conveying steering misalignment caused by initial skew. The correction, limiting and protection functions of the conveying protection component can adapt to crystalline silicon panels of different sizes, can flexibly match the production needs of crystalline silicon panels of various specifications, meet the needs of multi-variety switching within the same production line, and improve applicability.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] The present invention provides the following embodiments: See also Figures 1 to 14 As shown, a conveyor steering mechanism for processing crystalline silicon panels includes a conveyor base 11 and four electric telescopic rods 12. Each of the four electric telescopic rods 12 is fixedly connected to the top surface of the conveyor base 11. The ends of the telescopic shafts of the four electric telescopic rods 12 are fixedly connected to a roller frame 13. Multiple load-bearing rollers 14 are rotatably connected to the roller frame 13 in a linear array. A servo motor 15 is fixedly connected to the top of the conveyor base 11. The output shaft end of the servo motor 15 is fixedly connected to a steering plate 16, which is located above the roller frame 13. A visual sensor 17 is fixedly connected to the conveyor base 11. The electric telescopic rods 12 control the raising and lowering of the roller frame 13 and the multiple load-bearing rollers 14, while the servo motor 15 controls the rotation of the steering plate 16.

[0022] Among them: reference Figures 2 to 7 As shown, all the supporting rollers 14 are connected by a transmission device, which can drive the supporting rollers 14 to rotate. Preferably, the transmission device can be a motor + chain + sprocket combination. Specifically, each supporting roller 14 is fixedly connected to a sprocket, and the sprockets of all the supporting rollers 14 are connected by the chain. The motor is fixedly connected to one of the supporting rollers 14, and the motor drives the supporting roller 14 to rotate. The sprocket and chain drive then drive all the supporting rollers 14 to rotate. Each supporting roller 14 is fixedly connected to a plurality of rollers, which are used to transport the steered crystalline silicon plate 19.

[0023] Among them: reference Figure 4As shown, the steering plate 16 is provided with a plurality of grid holes in a mesh shape, and the grid holes of the steering plate 16 correspond to the positions of the rollers on the carrying roller 14. When the roller frame 13 and the carrying roller 14 are lifted, the rollers on the carrying roller 14 pass upward through the grid holes of the steering plate 16, and the tops of the rollers are exposed upward from the grid holes of the steering plate 16; when the roller frame 13 and the carrying roller 14 are lowered, the rollers on the carrying roller 14 descend from the grid holes of the steering plate 16, so that the rollers on the carrying roller 14 are located below the steering plate 16.

[0024] Wherein: the visual sensor 17 is used to monitor the position status of the crystalline silicon plate 19 on the roller frame 13.

[0025] Wherein: conveyor base 11 is provided with conveyor lines on both sides for conveying the crystalline silicon plate 19 to different processing steps, and the conveyor base 11 and the structure thereon are used for conveying and diverting the crystalline silicon plate 19. Figure 1 As shown here, the example of rotating the crystalline silicon plate 19 90 degrees for transportation is used. The crystalline silicon plate 19 is rotated horizontally 90 degrees to accommodate the transportation requirements of the crystalline silicon plate 19 in different subsequent processing steps. The rotation of the servo motor 15 drives the steering plate 16 to rotate synchronously with the crystalline silicon plate 19, thus achieving directional rotation of the steering plate 16.

[0026] In summary, Figure 1 As a position reference, when the crystalline silicon plate 19 is Figure 1 When the conveyor line on the left is conveying toward the roller frame 13, the telescopic shafts of all the electric telescopic rods 12 are extended, and the rollers of the carrying rollers 14 are exposed upward from the grid holes of the steering plate 16. The conveyor line on the left conveys the crystalline silicon plate 19 to the carrying rollers 14, so that the crystalline silicon plate 19 contacts the top surface of the rollers of the carrying rollers 14 and is driven by the carrying rollers 14 to move toward the conveyor line on the right. When the visual sensor 17 detects that the crystalline silicon plate 19 has moved to the center position of the steering plate 16, the carrying roller 14 stops rotating, and the telescopic shafts of the electric telescopic rods 12 are retracted, so that the rollers of the carrying rollers 14 move down to the steering plate 16. 6, the crystalline silicon plate 19 follows the carrying roller 14 and descends synchronously until the crystalline silicon plate 19 falls on the top surface of the steering plate 16. At this time, the output shaft of the servo motor 15 rotates, and the output shaft of the servo motor 15 drives the steering plate 16 to rotate synchronously, and then the steering plate 16 drives the crystalline silicon plate 19 thereon to rotate. When the crystalline silicon plate 19 is turned, the output shaft of the servo motor 15 stops rotating, and the telescopic shaft of the electric telescopic rod 12 extends, so that the crystalline silicon plate 19 is again contacted by the rollers of the multiple carrying rollers 14. The crystalline silicon plate 19 moves up and no longer contacts the steering plate 16, and then the carrying rollers 14 start to rotate. Through the rotation of the multiple carrying rollers 14, the oriented and rotated crystalline silicon plate 19 is transported to Figure 1On the right conveyor line, the conveying and steering of the crystalline silicon plate 19 is completed. Since the two sides of the roller frame 13 are connected to the conveyor lines of different processing steps, the conveying of the crystalline silicon plate 19 between different processes and the steering adjustment of the placement direction of the crystalline silicon plate 19 itself are realized.

[0027] A conveying protection assembly is provided on the conveyor base 11, and the conveying protection assembly includes two support plates 21, and the two support plates 21 are symmetrically fixedly connected to the steering plate 16. The top of the two support plates 21 is fixedly connected to a load-bearing rod 22, and the two load-bearing rods 22 are each slidably connected to two sliding frames 23. A threaded hole is provided on the top of each sliding frame 23, and a threaded rod 24 is threadedly connected in the threaded hole. The bottom end of each threaded rod 24 is fixedly connected to a friction pad 25, and the friction pad 25 is located inside the sliding frame 23. Each slide frame 23 is fixedly connected to an electric telescopic rod 26 at its bottom end. The telescopic axis end of each electric telescopic rod 26 is fixedly connected to a carrier plate 27. Each carrier plate 27 is provided with two chute slots 28, which are perpendicular to each other. A slide plate 29 is slidably connected within each chute 28. Two fixed plates 1 210 and two fixed plates 211 are fixedly connected to each carrier plate 27. The two fixed plates 1 210 are located at the ends where the two chute slots 28 are close to each other, and the two fixed plates 211 are located at the ends where the two chute slots 28 are separated from each other. A guide rod 212 is fixedly connected between the fixed plates 1 210 and 211. The slide plates 29 are slidably connected to the guide rods 212. Each guide rod 212 is fitted with a spring 213. The ends of the guide rods 212 are fixedly connected to the adjacent fixed plates 1 210 and 211. The ends of the spring 213 are fixedly connected to the slide plate 29 and the fixed plate 2 211, respectively. Each slide plate 29 is fixedly connected to a stopper 214 at its bottom end. Stopper 214 is located below the support plate 27. A rubber pad 215 is fixedly connected to each stopper 214. A rubber belt 216 is fixedly connected between the two stoppers 214 on each support plate 27. Each support plate 27 is fixedly connected to a third electric telescopic rod 217, and a push rod 218 is fixedly connected to the output shaft end of each electric telescopic rod 217.

[0028] Among them: reference Figure 2 As shown, the support plates 21 are configured to be U-shaped, and the two support plates 21 extend outward on the deflection plate 16 so as not to block the normal conveying path of the crystalline silicon plate 19 on the roller frame 13 .

[0029] Among them: reference Figure 10As shown, the user can tighten or loosen the threaded rod 24 on the slide frame 23 so that the friction pad 25 moves up and down in the slide frame 23. When the friction pad 25 contacts and squeezes the top surface of the load-bearing rod 22, the position of the slide frame 23 on the load-bearing rod 22 is fixed by the squeezing force of the friction pad 25 and the friction force between the friction pad 25 and the load-bearing rod 22. Conversely, when the threaded rod 24 is loosened, the friction pad 25 rises and no longer contacts the load-bearing rod 22. The user can then adjust the position of the slide frame 23 on the load-bearing rod 22 by sliding the slide frame 23 on the load-bearing rod 22.

[0030] Among them: reference Figure 8 、 Figure 12 As shown, the stopper 214 , the rubber pad 215 and the rubber belt 216 are all located below the supporting plate 27 .

[0031] Among them: reference Figure 5 As shown, the push rod 218 is configured to be L-shaped, and both sides of the push rod 218 are respectively perpendicular to the two slide grooves 28 , and both sides of the push rod 218 are respectively in contact with the two slide plates 29 .

[0032] Before using the conveying protection component, the user adjusts the positions of the four sliding frames 23 on the corresponding supporting rods 22 according to the size of the crystalline silicon plate 19 to be conveyed and diverted, so that the four sliding frames 23 can be located at the corners of the crystalline silicon plate 19 respectively. The specific adjustment method has been described above and will not be repeated here.

[0033] When the crystalline silicon plate 19 has just been conveyed to the top of the steering plate 16 and the rollers of the carrying rollers 14 have dropped below the steering plate 16, and the crystalline silicon plate 19 has not yet been driven to turn by the output shaft of the servo motor 15, the conveying protection assembly starts. At this time, the conveying protection assembly operates as follows: After the visual sensor 17 detects that the crystalline silicon plate 19 is parked firmly on the steering plate 16, the telescopic shaft of the second electric telescopic rod 26 is extended. As the telescopic shaft of the second electric telescopic rod 26 is extended, the supporting plate 27 moves downward synchronously with the second electric telescopic rod 26. When the bottom ends of the rubber pads 215 at the bottom of the supporting plate 27 all touch the top surface of the steering plate 16, the telescopic shaft of the second electric telescopic rod 26 stops extending, and the telescopic shaft of the third electric telescopic rod 217 is extended. As the telescopic shaft of the third electric telescopic rod 217 is extended, the telescopic shaft of the third electric telescopic rod 217 drives the push rod 218 to move synchronously, and then the push rod 218 pushes the slide plate 29 to slide along the corresponding slide groove 28. At this time, the spring 213 is elastically stretched, and as the two slide plates 29 move, the slide plate 29 drives the resistance block at the bottom. 214 and the rubber pad 215 move toward the crystalline silicon plate 19 until the rubber pad 215 contacts the crystalline silicon plate 19. At this time, the rubber pad 215 contacts the two side edges of the corners of the crystalline silicon plate 19 and pushes inward. Since the four sliding frames 23 are respectively located at the corners of the crystalline silicon plate 19, the side edges of the four corners of the crystalline silicon plate 19 are all subjected to inward pushing pressure. If the crystalline silicon plate 19 has previously slipped laterally and deflected at an angle during the transportation process, the pressure on the four corners of the crystalline silicon plate 19 will correct the position of the crystalline silicon plate 19, and as the two rubber pads 215 at the bottom of the same carrier plate 27 contact the side edges of the corners of the crystalline silicon plate 19, the rubber belt 216 between the two rubber pads 215 will contact the corners of the crystalline silicon plate 19, forming physical protection for the corners of the crystalline silicon plate 19.

[0034] After completion, the output shaft of the driving servo motor 15 of the conveyor base 11 rotates, and the output shaft of the servo motor 15 drives the steering plate 16 to rotate synchronously, and then the steering plate 16 drives the crystalline silicon plate 19 thereon to turn. When the turning of the crystalline silicon plate 19 is completed, the output shaft of the servo motor 15 stops rotating. During this process, the crystalline silicon plate 19 is in a state where the side is restrained by the rubber pad 215 and the four corners are restrained and protected by the rubber belt 216. The side of the crystalline silicon plate 19 is restrained and limited by the rubber pad 215, which can prevent the crystalline silicon plate 19 from shaking during the turning process. The four corners of the crystalline silicon plate 19 are restrained and protected by the rubber belt 216, which can prevent the corners of the crystalline silicon plate 19 from colliding during the turning process. The rubber belt 216 is soft and will not damage the corners of the crystalline silicon plate 19.

[0035] It should be noted that: since the bearing rod 22 is fixedly connected to the steering plate 16 through the support plate 21, when the steering plate 16 rotates, the four bearing plates 27 rotate synchronously, that is, during the steering process of the crystalline silicon plate 19, the four corners of the crystalline silicon plate 19 are protected.

[0036] When the crystalline silicon plate 19 is turned, it needs to be transported to another conveyor line, the telescopic shaft of the electric telescopic rod three 217 is retracted, and the push rod 218 no longer applies thrust to the two slides 29. Under the elastic contraction of the spring 213, the two slides 29 drive the bottom block 214 to move back in the direction away from the crystalline silicon plate 19, and the rubber pad 215 and the rubber belt 216 no longer conflict with the crystalline silicon plate 19. Then the telescopic shaft of the electric telescopic rod two 26 is retracted, so that the carrying plate 27 moves upward, and the block 214 and the rubber pad 215 are no longer located on the conveying path of the crystalline silicon plate 19. After completion, the telescopic shaft of the electric telescopic rod one 12 is extended, so that the rollers on the multiple carrying rollers 14 move upward and expose the square holes on the steering plate 16, so as to contact and lift the crystalline silicon plate 19, and then the carrying roller 14 rotates, so that the carrying roller 14 drives the crystalline silicon plate 19 to be transported to another conveyor line.

[0037] It should be noted that: in the above process, the position of the sliding frame 23 on the bearing rod 22 is adjustable, so that the correction, limiting and protection functions of the rubber pad 215 and the rubber belt 216 can adapt to crystalline silicon panels 19 of various sizes.

[0038] In summary, the operation of the conveying protection component can achieve the following beneficial effects: First, in the prior art, the crystalline silicon plate 19 is prone to lateral slippage and angular deviation during the transportation and turning process, causing the position to deviate from the preset trajectory when entering the next process, requiring shutdown and adjustment.

[0039] Through the operation of the conveying protection component, rubber pads 215 that push inward are set at the four corners of the crystalline silicon plate 19, which can form a stable constraint on the crystalline silicon plate 19 from the four sides, and fix the crystalline silicon plate 19 when the crystalline silicon plate 19 turns, preventing the crystalline silicon plate 19 from sliding laterally or shifting at an angle, ensuring that it always maintains a stable posture and preset trajectory during the turning process, avoiding the problem of position deviation.

[0040] Second, in the prior art, when the crystalline silicon plate 19 turns, its four corners are prone to collision and scratching with other hard components, causing the crystalline silicon plate 19 to crack, chip or break at the edge.

[0041] Through the operation of the conveying protection component, a rubber belt 216 is designed to wrap the four corners of the crystalline silicon plate 19. The rubber belt 216 can serve as a buffer and isolation structure to prevent the four corners of the crystalline silicon plate 19 from directly contacting other hard components and avoid collision between the crystalline silicon plate 19 and other components.

[0042] Third: Through the operation of the conveying protection component, the crystalline silicon plate 19 can be corrected, and the skewed crystalline silicon plate 19 can be adjusted to the preset correct posture while turning, ensuring that it is accurately positioned when entering the next process, and is more consistent with the alignment of subsequent processing equipment, avoiding the problem of conveying steering misalignment caused by the initial skew.

[0043] Fourth: The correction, limiting and protection functions of the conveying protection component can adapt to crystalline silicon panels 19 of different sizes, can flexibly match the production needs of crystalline silicon panels 19 of various specifications, meet the needs of multi-variety switching within the same production line, and improve applicability.
