Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically to a conveying and steering mechanism for processing crystalline silicon plates. Background Technology

[0002] The conveyor steering mechanism for crystalline silicon board processing is an automated equipment component used to adjust the transmission direction of crystalline silicon boards on the conveyor line. It is a key auxiliary device in the crystalline silicon board manufacturing production line, which can be used to connect different processing steps, ensure that crystalline silicon boards flow efficiently and smoothly between various production stages, and improve production continuity and automation level.

[0003] However, in actual use, when the existing conveying and turning mechanism turns the silicon wafer, the silicon wafer may slip laterally due to the centrifugal force and slight lateral force acting on it during the turning process. This causes the silicon wafer to deviate from the preset trajectory when it enters the next process, often requiring a machine stop for adjustment, which affects the continuity of production.

[0004] Furthermore, during the turning process, the four corners of the crystalline silicon plate are prone to collision and scratches with the rigid parts of the conveying mechanism (such as metal baffles and the edge of the rotating shaft), resulting in microcracks, missing corners or edge breakage, which directly affects the product yield.

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

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0041] The embodiments provided by the present application include:

[0042] Please refer to Figures 1 to 14 ​As shown in the figure, a kind of conveying steering mechanism for processing crystalline silicon plate, including conveyor base 11 and four electric telescopic rods one 12, four electric telescopic rods one 12 are all fixedly connected on the top surface of conveyor base 11, the telescopic shaft end of four electric telescopic rods one 12 is commonly fixedly connected with a roller bracket 13, a plurality of bearing rollers 14 are rotatably connected in straight array in roller bracket 13, the top of conveyor base 11 is fixedly connected with servo motor 15, the output shaft end of servo motor 15 is fixedly connected with steering plate 16, steering plate 16 is located above roller bracket 13, visual sensor 17 is fixedly connected on conveyor base 11.Electric telescopic rod one 12 is used to control the lifting of roller bracket 13 and a plurality of bearing rollers 14, servo motor 15 is used to control the rotation of steering plate 16.

[0043] Wherein: refer to Figures 2 to 7 As shown in the figure, all bearing rollers 14 are connected by transmission device, and the transmission device can drive the rotation of bearing rollers 14, preferably, the transmission device can be motor+chain+chain wheel combination, specifically, a chain wheel is fixedly connected on each bearing roller 14, all bearing rollers 14 are drivingly connected by chain, a motor is fixedly connected with one of bearing rollers 14, the rotation of the bearing roller 14 is driven by the motor, and the rotation of all bearing rollers 14 is driven by the transmission of chain wheel and chain. A plurality of rollers are fixedly connected on each bearing roller 14, and the rollers are used to convey and steer crystalline silicon plate 19.

[0044] Wherein: refer to Figure 4 As shown in the figure, a plurality of square holes are formed in the form of net on steering plate 16, the square holes of steering plate 16 correspond to the positions of the rollers on bearing rollers 14, when roller bracket 13 and bearing rollers 14 are lifted, the rollers on bearing rollers 14 penetrate into the square holes of steering plate 16 upward, and the top of the rollers exposes the square holes of steering plate 16 upward, when roller bracket 13 and bearing rollers 14 are lowered, the rollers on bearing rollers 14 are lowered from the square holes of steering plate 16, so that the rollers on bearing rollers 14 are located below steering plate 16.

[0045] Wherein: visual sensor 17 is used to monitor the position state of crystalline silicon plate 19 on roller bracket 13.

[0046] Wherein: conveyor base 11 is provided with conveying line on both sides, for conveying crystalline silicon plate 19 to different processing procedures, and the conveyor base 11 and the structure thereon are used to convey and steer crystalline silicon plate 19. Specifically: refer to Figure 1 As shown in the figure, crystalline silicon plate 19 is horizontally rotated by ninety degrees, for example, to adapt to the conveying requirements of different processing procedures for the placing direction of crystalline silicon plate 19. The rotation of servo motor 15 can drive steering plate 16 and crystalline silicon plate 19 to rotate synchronously, that is, directional rotation of steering plate 16 is formed.

[0047] In summary,Figure 1 For position reference, when the crystalline silicon plate 19 is... Figure 1 When the left conveyor line transports the silicon wafer 19 towards the roller frame 13, the telescopic shafts of all the electric telescopic rods 12 extend, and the rollers of the bearing rollers 14 protrude upwards through the square holes of the steering plate 16. The left conveyor line transports the silicon wafer 19 onto the bearing rollers 14, causing the silicon wafer 19 to contact the top surface of the rollers of the bearing rollers 14 and be driven by the bearing rollers 14 to move towards the right conveyor line. When the vision sensor 17 detects that the silicon wafer 19 has moved to the center position of the steering plate 16, the bearing rollers 14 stop rotating, and the telescopic shafts of the electric telescopic rods 12 retract, causing the rollers of the bearing rollers 14 to move downwards onto the steering plate 16. Below 6, the silicon wafer 19 descends synchronously with the carrying roller 14 until it lands on the top surface of the steering plate 16. At this point, the output shaft of the servo motor 15 rotates, driving the steering plate 16 to rotate synchronously. The steering plate 16 then drives the silicon wafer 19 to rotate. After the silicon wafer 19 completes its rotation, the output shaft of the servo motor 15 stops rotating, and the telescopic shaft of the electric telescopic rod 12 extends, causing the silicon wafer 19 to be again pressed against the rollers of the multiple carrying rollers 14. The silicon wafer 19 moves upward and no longer presses against the steering plate 16, then the carrying rollers 14 begin to rotate. Through the rotation of the multiple carrying rollers 14, the oriented silicon wafer 19 is transported to... Figure 1 On the right-hand conveyor line, the silicon wafer 19 is conveyed and turned. Since the roller frame 13 is connected to the conveyor lines of different processing steps on both sides, the silicon wafer 19 is conveyed between different processes and the orientation of the silicon wafer 19 itself is adjusted.

[0048] The conveyor base 11 is provided with a conveying protection assembly, which comprises two support plates 21 symmetrically fixedly connected to the turning plate 16, one bearing rod 22 fixedly connected to the top end of each support plate 21, two sliding frames 23 slidingly connected to the bearing rod 22, a threaded hole provided at the top of each sliding frame 23, a threaded rod 24 threadedly connected to the threaded hole, one friction pad 25 fixedly connected to the bottom end of each threaded rod 24 and located inside the sliding frame 23, one electric telescopic rod II 26 fixedly connected to the bottom end of each sliding frame 23, one bearing plate 27 fixedly connected to the telescopic shaft end of each electric telescopic rod II 26, two sliding grooves 28 perpendicularly arranged on the bearing plate 27, one sliding plate 29 slidingly connected to each sliding groove 28, two fixed plates I 210 and two fixed plates II 211 fixedly connected to each bearing plate 27, the two fixed plates I 210 located at one end of the two sliding grooves 28 close to each other, the two fixed plates II 211 located at one end of the two sliding grooves 28 away from each other, a guide rod 212 fixedly connected between the fixed plate I 210 and the fixed plate II 211, the sliding plate 29 slidingly connected to the guide rod 212, one spring 213 sleeved on each guide rod 212, the two ends of the guide rod 212 fixedly connected to the adjacent fixed plate I 210 and fixed plate II 211, and the two ends of the spring 213 fixedly connected to the sliding plate 29 and the fixed plate II 211 respectively, one stopper 214 fixedly connected to the bottom end of each sliding plate 29 and located below the bearing plate 27, one rubber pad 215 fixedly connected to each stopper 214, and one rubber belt 216 fixedly connected between the two stoppers 214 on each bearing plate 27. One electric telescopic rod III 217 is fixedly connected to each bearing plate 27, and one push rod 218 is fixedly connected to the output shaft end of each electric telescopic rod III 217.

[0049] As shown in Figure 2 As shown in the drawings, the support plate 21 is provided in a U shape, and the two support plates 21 extend outwardly on the turning plate 16 without blocking the normal conveying path of the silicon wafer 19 on the roller frame 13.

[0050] As shown in Figure 10 As shown in the drawings, the user can threadedly tighten or loosen the threaded rod 24 on the sliding frame 23, so that the friction pad 25 moves up and down in the sliding frame 23. When the friction pad 25 abuts against and presses the top surface of the bearing rod 22, the position of the sliding frame 23 on the bearing rod 22 is fixed through the pressing force of the friction pad 25 and the friction force between the friction pad 25 and the bearing rod 22. Conversely, when the threaded rod 24 is loosened, the friction pad 25 rises and no longer abuts against the bearing rod 22, and then the user can adjust the position of the sliding frame 23 on the bearing rod 22 by sliding the sliding frame 23 on the bearing rod 22.

[0051] Wherein: refer to Figure 8 , Figure 12 As shown in the figure, the block 214, the rubber pad 215 and the rubber belt 216 are all below the bearing plate 27.

[0052] Wherein: refer to Figure 5 As shown in the figure, the push rod 218 is L-shaped, and the two sides of the push rod 218 are perpendicular to the two sliding grooves 28 respectively, and the two sides of the push rod 218 are in contact with the two sliding plates 29 respectively.

[0053] Before the conveying protection assembly is used, the user adjusts the positions of the four sliding frames 23 on the corresponding bearing rods 22 according to the size of the crystalline silicon plate 19 to be conveyed and turned, so that the four sliding frames 23 can be located at the corner positions of the crystalline silicon plate 19. The specific adjustment method has been described above, and will not be described here.

[0054] When the crystalline silicon plate 19 is just conveyed to the top of the turning plate 16, and the rollers of the bearing roller 14 are lowered below the turning plate 16, and the crystalline silicon plate 19 has not been rotated by the output shaft of the servo motor 15, the conveying protection assembly is started, and at this time the conveying protection assembly operates as follows:

[0055] After the visual sensor 17 monitors that the crystalline silicon plate 19 is stably parked on the turning plate 16, the telescopic shaft of the electric telescopic rod two 26 is extended, and as the telescopic shaft of the electric telescopic rod two 26 is extended, the bearing plate 27 follows the electric telescopic rod two 26 and moves downward synchronously, and when the bottom ends of the rubber pads 215 at the bottom of the bearing plate 27 are in contact with the top surface of the turning plate 16, the telescopic shaft of the electric telescopic rod two 26 stops extending, the telescopic shaft of the electric telescopic rod three 217 is extended, and as the telescopic shaft of the electric telescopic rod three 217 is extended, the telescopic shaft of the electric telescopic rod three 217 drives the push rod 218 to move synchronously, and then the push rod 218 pushes the sliding plates 29 to slide along the corresponding sliding grooves 28, at this time the springs 213 are elastically stretched, and as the two sliding plates 29 move, the sliding plates 29 drive the bottom end blocks 214 and the rubber pads 215 to move towards the crystalline silicon plate 19, until the rubber pads 215 are in contact with the crystalline silicon plate 19, at this time the rubber pads 215 are in contact with the two side edges of the corner of the crystalline silicon plate 19 and are pushed inward, and since the four sliding frames 23 are located at the corner positions of the crystalline silicon plate 19, at this time the side edges of the four corners of the crystalline silicon plate 19 are subjected to the pressure of being pushed inward, and if the crystalline silicon plate 19 has lateral slip and angle deviation during the conveying 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 bearing plate 27 are in contact with the side edges of the corners of the crystalline silicon plate 19, the rubber belt 216 between the two rubber pads 215 will be in contact with the corners of the crystalline silicon plate 19, and the corners of the crystalline silicon plate 19 will be physically protected.

[0056] After the completion, the output shaft of the drive servo motor 15 of the conveyor base 11 rotates, the output shaft of the servo motor 15 drives the synchronous rotation of the steering plate 16, and the steering plate 16 drives the steering of the silicon wafer 19 on it. When the steering of the silicon wafer 19 is completed, the output shaft of the servo motor 15 stops rotating, and in this process, the silicon wafer 19 is in a state of being limited by the rubber pad 215 on the side and being protected by the rubber belt 216 on the four corners. The side of the silicon wafer 19 is limited by the rubber pad 215, which can prevent the silicon wafer 19 from shaking during steering. The four corners of the silicon wafer 19 are protected by the rubber belt 216, which can prevent the silicon wafer 19 from colliding with the corners during steering. The rubber belt 216 is soft and will not damage the corners of the silicon wafer 19.

[0057] It should be noted that: since the bearing rod 22 is fixedly connected with the steering plate 16 through the support plate 21, the four bearing plates 27 are synchronously rotated when the steering plate 16 rotates, that is, the four corners of the silicon wafer 19 are protected during the steering of the silicon wafer 19.

[0058] When the steering of the silicon wafer 19 is completed and the silicon wafer 19 needs to be conveyed to another conveying line, the telescopic shaft of the electric telescopic rod three 217 is retracted, and the push rod 218 no longer applies a pushing force to the two sliding plates 29. Under the elastic contraction of the spring 213, the two sliding plates 29 drive the bottom abutting block 214 to move away from the silicon wafer 19 and reset, and then the rubber pad 215 and the rubber belt 216 no longer abut against the silicon wafer 19. Then the telescopic shaft of the electric telescopic rod two 26 is retracted, so that the bearing plate 27 moves upward, and then the abutting block 214 and the rubber pad 215 are no longer located on the conveying path of the silicon wafer 19. After the completion, the telescopic shaft of the electric telescopic rod one 12 is extended, so that the rollers on the plurality of bearing rollers 14 move upward and expose the square holes on the steering plate 16, abut against and lift the silicon wafer 19, and then the bearing rollers 14 rotate to convey the silicon wafer 19 to another conveying line.

[0059] 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 of the rubber pad 215 and the rubber belt 216 can adapt to silicon wafers 19 of various sizes.

[0060] In summary, through the operation of the conveying protection assembly, the following beneficial effects can be achieved:

[0061] Firstly, in the prior art, the silicon wafer 19 is prone to horizontal sliding and angular deviation during conveying and steering, which causes the position to deviate from the preset track when entering the next process, and the machine needs to be stopped for adjustment.

[0062] And through the operation of the conveying protection assembly, the inwardly extruding rubber pad 215 is arranged at the four corners of the crystalline silicon plate 19, which can form stable constraints on the crystalline silicon plate 19 from the four sides, fix the crystalline silicon plate 19 when it is turned, prevent the crystalline silicon plate 19 from sliding or angular deviation, ensure that it always maintains a stable posture and a preset trajectory during turning, and avoid position deviation.

[0063] Secondly, in the prior art, the four corners of the crystalline silicon plate 19 are prone to collide and scratch with other hard components when it is turned, which causes the crystalline silicon plate 19 to be cracked, cornerless or edge broken.

[0064] And through the operation of the conveying protection assembly, the rubber belt 216 wrapping the four corners of the crystalline silicon plate 19 is designed, which can serve as a buffer and isolation structure to avoid the direct contact of the four corners of the crystalline silicon plate 19 with other hard components, and avoid the collision between the crystalline silicon plate 19 and other components.

[0065] Thirdly,

[0066] Through the operation of the conveying protection assembly, the crystalline silicon plate 19 can be corrected, and the skewed crystalline silicon plate 19 can be adjusted to a preset correct posture while turning, so as to ensure that it is accurately positioned when entering the next process and better matches the alignment of subsequent processing equipment, thereby avoiding the problem of misalignment caused by initial skewing.

[0067] Fourthly,

[0068] The correction, limiting and protection of the conveying protection assembly can adapt to crystalline silicon plates 19 of different sizes, can flexibly match the production needs of crystalline silicon plates 19 of various specifications, can meet the needs of multi-variety switching in the same production line, and can improve the applicability.
