Description

Technical Field

[0001] This utility model relates to the field of conveying technology, and in particular to a deviation correction device and a handling system. Background Technology

[0002] In recent years, the global photovoltaic industry has experienced explosive growth, with crystalline silicon solar cells dominating the market due to their mature production processes and high conversion efficiency. Automated loading and unloading equipment for crystalline silicon solar cells plays a crucial role in the automation of the photovoltaic manufacturing industry. Its main function is to handle the turnover of workpieces between different process stages, achieving fully automated handling of workpieces in the basket-carrier, replacing manual handling, and reducing the risk of product contamination caused by excessive contact between humans and workpieces.

[0003] The main function of automated loading and unloading equipment for crystalline silicon cells is to load, unload, and transfer workpieces between different process stages. During this process, a correction device is needed to correct the position of the workpieces. Existing correction devices generally adopt a lifting module + support platform architecture. The lifting module drives the support platform to move vertically, and then a drive module is set on the support platform to correct the position of the workpieces.

[0004] However, if there is a need for multiple support platforms, each additional support platform will require a separate lifting module, resulting in an increase in equipment size and footprint. Utility Model Content

[0040] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0041] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0042] In some embodiments, such as Figures 1-2 As shown, this utility model proposes a correction device, comprising:

[0043] A support plate 10 is provided, and support platforms 20 are slidably connected to its two sides along the vertical direction; the two support platforms 20 are connected by a connecting structure 101; at least one row of planar correction mechanisms 40 extending in the horizontal direction is provided on the top of each of the two support platforms 20, and all the planar correction mechanisms 40 are provided with an adsorption surface for adsorbing the workpiece.

[0044] A transmission assembly 50, the output end of which is connected to one of the support platforms 20, is used to drive all the support platforms 20 and the planar correction mechanism 40 to rise and fall in the vertical direction.

[0045] It should be noted that the support plate 10 proposed in this embodiment is mounted on the frame of the conveying system. Furthermore, the correction device proposed in this embodiment also includes a main control unit (not shown, the same applies throughout). The horizontal direction proposed in this embodiment is preferably the X-axis direction or the length direction of the support plate 10, the vertical direction is preferably the Z-axis direction or the height direction of the support plate 10, and the Y-axis direction is preferably the width direction of the support plate 10.

[0046] Thus, when the correction device is activated, the main control unit activates the transmission assembly 50, causing it to lift one of the support platforms 20 vertically to a specified height. Simultaneously, this support platform 20, through the connecting structure 101, lifts the other support platform 20 to the specified height, ensuring that the adsorption surfaces of all planar correction mechanisms 40 are higher than the carrier placement surface. Then, the workpiece removal structure (preferably an adsorption fixture or gripper, etc., not limited here) places the workpiece onto the adsorption surface of the planar correction mechanism 40. The main control unit receives the workpiece position positioning data from the CCD and then directs it to the planar... The correction mechanism 40 sends a command, and the planar correction mechanism 40 performs corresponding position offsets in the X-axis, Y-axis, and θ-axis directions according to the command. After the offset command is completed, all four sides of the workpiece are within the carrier pocket. At this time, the main control unit controls the transmission component 50 to drive one of the support platforms 20 to descend vertically. At this time, the support platform 20 drives the other support platform 20 to descend synchronously through the connecting structure 101, so that the workpiece falls smoothly into the carrier. Then the planar correction mechanism 40 stops adsorbing the workpiece and completes the entire action process. This can ensure the positional accuracy of the workpiece in the carrier and improve the coating effect.

[0047] Therefore, this utility model can simultaneously drive two support platforms 20 and corresponding planar correction mechanisms 40 to lift and lower synchronously through a single transmission component 50, thereby optimizing the structure of the correction device and reducing its volume or space occupation.

[0048] The support platform 20 is preferably L-shaped, consisting of a vertical plate and a horizontal plate, with the horizontal plate located above the vertical plate. The transmission assembly 50 is disposed on the vertical plate of one of the support platforms 20. Multiple rows of planar correction mechanisms 40 are arranged along the Y-axis direction, with each row of planar correction mechanisms 40 having multiple planar correction mechanisms 40 extending horizontally.

[0049] In some embodiments, such as Figure 3 As shown, the supporting plate 10 is provided with a rack 102 extending in the vertical direction. This embodiment proposes a transmission assembly 50, including:

[0050] The power motor 501 is fixedly installed on one of the support platforms 20;

[0051] The drive shaft 504 is arranged horizontally and connected to the output end of the power motor 501;

[0052] Gear 506 is fixedly sleeved on the drive shaft 504, and gear 506 meshes with rack 102.

[0053] It should be noted that the gears 506 proposed in this embodiment are all fixedly connected to the drive shaft 504 by a flat key to serve as the power output end, and the gears 506 mesh with the corresponding racks 102 to realize power transmission, converting the rotational motion of the power motor 501 into vertical motion.

[0054] In this way, when the main control unit starts the power motor 501, the power motor 501 will drive the drive shaft 504 to rotate, and then the drive shaft 504 will drive the gear 506 to move up and down in the vertical direction on the corresponding rack 102, thereby driving the two support platforms 20 and the corresponding planar correction mechanism 40 to move up and down in the vertical direction.

[0055] In some embodiments, such as Figure 3 As shown, the transmission assembly 50 also includes a coupling 502 and a reducer 503;

[0056] The input shaft of the reducer 503 is connected to the output end of the power motor 501, and the output shaft of the reducer 503 is connected to the drive shaft 504 through the coupling 502.

[0057] In this way, the reducer 503 can reduce the speed and amplify the torque, that is, convert the high speed and low torque output of the power motor 501 into the low speed and high torque power required by the correction device; while the coupling 502 can establish a continuous torque transmission channel to compensate for the deviation of the drive shaft 504 and ensure the transmission accuracy of the drive shaft 504.

[0058] In some embodiments, to support the drive shaft 504 and bear the load, reduce frictional resistance, and maintain rotational accuracy, such as... Figure 3 As shown, the support platform 20 is provided with bearing seats 505 at both ends of the drive shaft 504, and the bearing seats 505 are rotatably connected to the ends of the drive shaft 504.

[0059] It should be noted that the bearing housing 505 proposed in this embodiment is equipped with a rolling bearing, which is rotatably connected to the end of the drive shaft 504. Furthermore, the power motor 501, reducer 503, and bearing housing 505 proposed in this embodiment are all fixedly mounted on the vertical plate of the support platform 20.

[0060] In some embodiments, the gear 506 is a helical gear and the rack 102 is a helical rack.

[0061] When the two support platforms 20 and the corresponding planar correction mechanism 40 are relatively heavy, the helical gear 506 has an advantage, ensuring that the transmission component 50 can more stably drive the heavier support platform 20 and the corresponding planar correction mechanism 40 to lift and lower.

[0062] Of course, in other embodiments, when the weight of the two support platforms 20 and the corresponding planar correction mechanism 40 is relatively light, the gear 506 can be a spur gear and the rack 102 can be a rack.

[0063] In some embodiments (not shown in the figures), there are two or more racks 102 and two or more gears 506, with the two or more gears 506 meshing with the two or more racks 102 in a one-to-one correspondence.

[0064] When each support platform 20 is equipped with at least two rows of planar correction mechanisms 40, resulting in a relatively heavy weight for the two support platforms 20 and their corresponding planar correction mechanisms 40, two or more gears 506 and racks 102 can be used to make the lifting and lowering of the correction device more stable.

[0065] Of course, when the number of planar correction mechanisms 40 on each support platform 20 is small, a set of gears 506 and racks 102 can also be used, which is not limited here.

[0066] In some embodiments, to ensure that the support platform 20 can be raised and lowered more stably, such as Figure 1 As shown, at least one guide rail 104 is provided on each side of the support plate 10 along the Y-axis direction, and the guide rails 104 extend in the vertical direction.

[0067] The two support platforms 20 are fitted with sliders (not shown, same throughout) on the corresponding guide rails 104, and the sliders slide on the corresponding guide rails 104.

[0068] In this way, the two support platforms 20 can slide vertically on the designated guide rail 104 via sliders to achieve stable lifting and lowering of the two support platforms 20 and avoid deviation.

[0069] In some embodiments, such as Figures 1-2 As shown, the bottom of the support platform 20 is provided with a buffer device 60, which is used to buffer and support the support platform 20.

[0070] It should be noted that this embodiment illustrates that each support platform 20 is provided with a buffer device 60 on both sides along the horizontal direction, and the buffer device 60 is vertically arranged along the vertical direction. The buffer device 60 is preferably a buffer cylinder, a hydraulic buffer, or a buffer spring. Of course, the buffer device 60 proposed in this embodiment is illustrated by a buffer cylinder. In this case, the cylinder seat of the buffer cylinder is fixed on the frame, and the piston rod of the buffer cylinder is connected to the support platform 20.

[0071] In this way, when the transmission assembly 50 drives the two support platforms 20 to rise and fall synchronously, the buffer device 60 will provide thrust to balance the gravity of the support platform 20 and the other components located on the support platform 20, so that the thrust can counteract the gravity, reduce the output load of the power motor 501, and realize the smooth lifting and lowering of the support platform 20.

[0072] In some embodiments, such as Figures 4-5 As shown, this embodiment proposes the composition of a planar correction mechanism 40, including:

[0073] An XY plane moving module (not shown, same throughout) is installed on the support platform 20;

[0074] A rotary motor 406 is installed at the output end of the XY plane motion module;

[0075] A support block 408 is installed at the output end of the rotary motor 406. The rotary motor 406 is used to drive the support block 408 to rotate in the XY plane. The support block 408 is provided with an air passage 409, which is used to connect to a vacuum generator (not shown, same throughout) to generate suction to adsorb the workpiece.

[0076] It should be noted that this embodiment uses four support blocks 408 as an example, and these four support blocks 408 are arranged in a rectangular shape; of course, the number of support blocks 408 can also be five or other numbers, and the arrangement shape of multiple support blocks 408 can also be circular or other shapes suitable for adsorbing the workpiece, which is not limited here. Furthermore, the material of the support blocks 408 proposed in this embodiment can be rubber or silicone. And each support block 408 proposed in this embodiment has an axially penetrating air passage 409.

[0077] In this way, when the support block 408 of the planar correction mechanism 40 has a workpiece attached, and the planar correction mechanism 40 receives a command from the main control unit, the XY planar movement module will drive the rotary motor 406 to move to the designated position. Then the rotary motor 406 will drive the support block 408 to rotate in place until it reaches the designated position. At this time, the main control unit will control the transmission component 50 to drive the two support platforms 20 to descend synchronously in the vertical direction so that the workpiece can fall smoothly into the carrier and then proceed with the subsequent process.

[0078] Furthermore, in this embodiment, the workpiece is placed on the adsorption surface of the support block 408 away from the rotary motor 406. This is equivalent to the support block 408 being located below the workpiece and adsorbing it, i.e., the support block 408 adsorbs the bottom surface of the workpiece. Compared to the scheme where the support block 408 is located above the workpiece for adsorption, this embodiment does not need to overcome the workpiece's own weight, thereby reducing the adsorption force and adsorption time, and avoiding damage to the surface film of the workpiece. Moreover, by only having the support block 408 in contact with the workpiece on a small area, the contact area with the workpiece can be reduced, avoiding the formation of suction cup marks on the surface film of the workpiece.

[0079] Specifically, the XY planar moving module includes a mounting base 401 disposed on the top of the support platform 20, a second motor 402 disposed on the mounting base 401, a second mounting seat 403 connected to the output end of the second motor 402, a first motor 404 disposed on the second mounting seat 403, a first mounting seat 405 connected to the output end of the first motor 404, a rotary motor 406 disposed on the first mounting seat 405, and an outer cover 407 connected to the output end of the rotary motor 406 extending in the vertical direction, the outer cover 407 being provided with a support block 408 for adsorbing workpieces.

[0080] When the support block 408 of the planar alignment mechanism 40 holds a workpiece and the planar alignment mechanism 40 receives a command from the main control unit, the second motor 402 will drive the second mounting base 403 and the components located on the second mounting base 403 to move linearly along the X-axis until the first designated position is reached; then the first motor 404 will drive the first mounting base 405 and the components located on the first mounting base 405 to move linearly along the Y-axis until the second designated position is reached; then the rotary motor 406 will drive the outer cover 407 and the workpiece held by the support block 408 to rotate in place until the third designated position is reached. At this time, the main control unit will control the transmission assembly 50 to drive the two support platforms 20 to descend synchronously in the vertical direction so that the workpiece can fall smoothly into the carrier, and then proceed with the subsequent process.

[0081] Specifically, to ensure that the first motor 404 can drive the first mounting base 405 to slide stably in the second direction and avoid deviation, such as Figure 4 As shown, the bottom of the first mounting base 405 is provided with a first slide rail 4051, and the first slide rail 4051 is slidably connected to the first sliding plate 4031 on the top of the second mounting base 403.

[0082] Specifically, to ensure that the second motor 402 can drive the second mounting base 403 to slide stably along the first direction and avoid deviation, such as Figure 4 As shown, the bottom of the second mounting base 403 is provided with a second slide rail 4032, and the second slide rail 4032 is slidably connected to the second slide plate 4011 on the top of the mounting base 401.

[0083] In some embodiments, to ensure that one transmission component 50 can simultaneously drive two support platforms 20 to move synchronously, such as Figure 2 As shown, the bottoms of the two support platforms 20 are connected by at least one connecting structure 101, and the bottom of the support plate 10 is fitted with a guide through hole 103 extending in the vertical direction corresponding to the connecting structure 101.

[0084] The connecting structure 101 moves up and down within the guide hole 103.

[0085] Thus, when the transmission assembly 50 drives one of the support platforms 20 to rise, that support platform 20 will drive the other support platform 20 to rise synchronously through the connecting structure 101. At this time, the connecting structure 101 moves upward through the guide hole 103. Similarly, when the transmission assembly 50 drives one of the support platforms 20 to fall, that support platform 20 will drive the other support platform 20 to fall synchronously through the connecting structure 101. At this time, the connecting structure 101 moves downward through the guide hole 103.

[0086] In some embodiments, to fine-tune the vertical deviation between the support plate 10 and the frame, meet the installation requirements of the alignment correction device, and improve the structural stability of the alignment correction device, such as... Figure 1 As shown, the bottom of both sides of the support plate 10 along the second direction is provided with a fixed seat 105. The fixed seat 105 is connected to the support plate 10 through an adjusting member 106. The adjusting member 106 is used to adjust the verticality of the support plate 10 and the frame.

[0087] It should be noted that the adjusting component 106 proposed in this embodiment is preferably an adjusting bolt and a shaft pin, and the adjusting component 106 is provided with anti-vibration measures such as shims, which will not be elaborated here.

[0088] In some embodiments, the present invention also provides a conveying system, the conveying system including the correction device as described above.

[0089] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
