Description

Technical Field

[0001] The invention relates to the technical field of silicon wafer production, and more specifically to a wafer inserting device for solar cell silicon wafers. Background Art

[0002] After the existing wafer insertion equipment stores the battery silicon wafers in batches in the flower basket, it transfers the flower baskets by positioning them, so as to realize the transfer of multiple groups of battery silicon wafers after the insertion. This requires that the loaded flower baskets must be transferred from the wafer insertion equipment by the conveying equipment first, and then the empty flower baskets are put back into the wafer insertion machine for positioning. There is a problem of conveying pauses in the process, resulting in poor continuity of battery silicon wafer insertion and low insertion efficiency. In view of this, we propose a wafer insertion device for solar cell silicon wafers. Summary of the invention

[0005] Preferably, two groups of positioning components are included, the positioning component includes an adjustment plate, a plurality of guide columns are fixedly mounted on the adjustment plate, the guide columns are slidably connected to the support components, an elastic member is mounted on the guide columns, one end of the elastic member is fixedly connected to the support component, and the other end is fixedly connected to the adjustment plate, a second limit column is fixedly mounted on the adjustment plate, an adjustment column is fixedly mounted on the adjustment plate, and a set spacing is provided between the adjustment column and the feeding end of the flower basket rack.

[0006] Preferably, the support assembly comprises a support frame, a fixing frame is fixedly mounted on the support frame, and two sets of limit plates are fixedly mounted on the support frame; The flower basket frame is provided with a positioning hole, and the limiting plate is plugged into and matched with the positioning hole; The support column is provided with a positioning groove, the limiting plate is plugged and matched with the corresponding positioning groove, and the limiting plate is inserted into the positioning groove and the positioning hole to limit the first limiting column.

[0007] Preferably, the axis of the limiting hole coincides with the axis of the corresponding first gear and the corresponding second gear, and the connecting column is coaxial with the corresponding limiting hole.

[0008] Preferably, the distance between the adjusting column and the feeding end of the flower basket rack is equal to the width of the first inclined block or the second inclined block.

[0009] Preferably, two groups of electric slides are fixedly mounted on the support frame, and the flower basket frame is fixedly mounted on the output ends of the corresponding electric slides, and the flower basket frame is slidably connected to the support frame.

[0010] Preferably, a torsion spring is mounted on the support column, one end of the torsion spring is fixedly connected to the support column, and the other end of the torsion spring is fixedly connected to the fixing plate.

[0011] Preferably, two groups of conveyor lines are fixedly mounted on the support frame for conveying battery silicon wafers. The positions of the conveyor lines correspond to the positions of the two groups of flower basket assemblies, and the conveyor lines are located between the corresponding flower basket boards.

[0013] By adopting the above scheme, when the conveyor line is conveying the battery silicon wafer, the sensing signal of the photoelectric sensor is in an open-interrupt cycle state. When the battery silicon wafer blocks the detection light of the photoelectric sensor, the sensing signal is interrupted, and the conveyor line continues to convey. At this time, the battery silicon wafer enters the limit slot. When the battery silicon wafer completely enters the limit slot and is limited by the first limit column, the photoelectric sensor senses the detection light again, and the output end of the electric slide drives the flower basket assembly to rise to the set height, drives the battery silicon wafer to rise, and switches the next vacant limit slot to the conveying position of the battery silicon wafer, preparing for the next storage of the battery silicon wafer.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The present invention controls the time when the connecting columns corresponding to the two groups of basket assemblies are alternately inserted into the first gear or the second gear, thereby controlling the continuous loading of the two groups of basket assemblies, and cooperating with the grabbing manipulator to batch transfer the battery silicon wafers after the insertion, thereby realizing the process of batch unloading without disassembling the basket, effectively solving the problem of discontinuity and low efficiency of the process of batch transferring battery silicon wafers by replacing the basket, and improving the continuity and efficiency of battery silicon wafer insertion.

[0016] 2. The present invention is provided with a rotatable first limit column. When inserting the wafer, the limit plate is inserted into the positioning groove to ensure that the first limit column is stably limited and at the same time ensure that the battery silicon wafer can be stably inserted into the limit groove for positioning during transportation. When the battery silicon wafers are transferred in batches, as the connecting column continues to rise and is inserted into the corresponding gear, the first limit column is controlled to rotate and disengage from the discharge side of the basket assembly under the action of the driving component, thereby avoiding interference with the grabbing robot when unloading. In addition, the connecting columns corresponding to the two groups of basket assemblies of the present invention are controlled by the same group of driving assemblies, which effectively reduces the number of driving devices, thereby reducing equipment costs and failure risks.

[0017] 3. When the driving assembly of the present invention controls the first limiting post to rotate away from the discharge side of the basket assembly, the driving assembly also controls the corresponding second limiting post to move toward the feed side of the basket assembly, thereby limiting and leveling one end of a plurality of battery silicon wafers. When the grabbing robot transfers the battery silicon wafers, the length dimension of the battery silicon wafers in the conveying direction can be effectively positioned, which facilitates the grabbing robot to accurately transfer the battery silicon wafers to the next process, and can effectively reduce the risk of battery silicon wafer damage caused by poor positioning accuracy during the transfer process.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Reference Figure 1The present embodiment discloses a wafer insertion device for solar cell silicon wafers, including a support assembly 1, the support assembly 1 includes a support frame 11, a through hole 12 is opened on the support frame 11, a fixing frame 13 is fixedly installed on the support frame 11, two groups of limit plates 14 are fixedly installed on the support frame 11, the limit plates 14 are located in the through hole 12, two groups of electric slides 2 are fixedly installed on the support frame 11, and basket assemblies 3 are installed at the output ends of the two groups of electric slides 2.

[0022] Reference Figures 1 to 6 The flower basket assembly 3 includes a fixed plate 31, which is fixedly installed at the output end of the electric slide 2. The fixed plate 31 is slidably connected to the support frame 11 through a guide rod 32. Two groups of support plates 33 are fixedly installed below the fixed plate 31, and a flower backboard 34 is fixedly installed on the support plate 33. The flower backboard 34 is perpendicular to the horizontal plane. A plurality of mutually parallel limiting grooves 35 are provided on the inner sides of the two groups of flower backboards 34. Rotary connecting holes 36 are provided on the two groups of support plates 33 in the flower basket assembly 3. Positioning holes 37 that are interconnected with the rotating connecting holes 36 are provided on the support plates 33, and the limiting plates 14 are plugged into and matched with the positioning holes 37.

[0023] A limit assembly 4 is installed on the support plate 33, and the limit assembly 4 includes a support column 41, which is rotatably matched with the rotating connection hole 36. A connecting rod 42 is fixedly installed on the support column 41, and a first limit column 43 is fixedly installed on the connecting rod 42. A positioning groove 44 is opened on the support column 41, and the limit plate 14 is plugged and matched with the corresponding positioning groove 44. When the positions of the positioning groove 44 and the positioning hole 37 correspond, the first limit column 43 is in a limited state, which is used to limit the transported silicon wafer. When the first limit column 43 is in the limited position, it abuts against the fixed plate 31. A connecting column 45 is fixedly installed on the top of the support column 41, and the connecting column 45 is a prism. A torsion spring 46 is mounted on the support column 41, one end of the torsion spring 46 is fixedly connected to the support column 41, and the other end is fixedly connected to the fixed plate 31.

[0024] Reference Figure 1 , Figure 2 , Figures 6 to 8A driving assembly 5 is installed on the fixed frame 13, and the driving assembly 5 includes a motor 51, a first gear 52 and an adjusting frame 53. The motor 51 is fixedly installed on the fixed frame 13, and the output shaft of the motor 51 is fixedly connected with the second gear 54. The first gear 52 is rotatably connected to the fixed frame 13. Limiting holes 55 are provided on the first gear 52 and the second gear 54. The axis of the limiting hole 55 coincides with the axis of the gear. The connecting column 45 is plugged into the corresponding limiting hole 55. The adjusting frame 53 is slidably connected to the fixed frame 13 through a guide rail 58. A first tilting block 56 and a second tilting block 57 are fixedly installed on the adjusting frame 53. A rack 59 is fixedly installed on the adjusting frame 53. The first gear 52 and the second gear 54 are both meshed with the rack 59 for transmission.

[0025] Reference Figure 1 and Fig. 9 Two groups of conveyor lines 6 are fixedly installed on the support frame 11 for conveying battery silicon wafers. Each group of conveyor lines 6 corresponds to a group of flower basket components 3. The conveyor lines 6 are located between the corresponding flower basket boards 34. Several photoelectric sensors 9 are fixedly installed on the support frame 11. The photoelectric sensors 9 are installed on the feeding side of the flower basket components 3. The transmitting end and the receiving end of the photoelectric sensor 9 are respectively located on the upper and lower sides of the conveyor line 6. When the conveyor line 6 conveys the battery silicon wafers, the sensing signal of the photoelectric sensor 9 is in an open-interrupt cycle state. When the battery silicon wafer blocks the detection light of the photoelectric sensor 9, the sensing signal is interrupted, and the conveyor line 6 continues to convey. At this time, the battery silicon wafer enters the limiting groove 35. When the battery silicon wafer completely enters the limiting groove 35 and is limited by the first limiting column 43, the photoelectric sensor 9 senses the detection light again. The output end of the electric slide 2 drives the flower basket component 3 to rise to a set height, drives the battery silicon wafer to rise, and switches the next vacant limiting groove 35 to the conveying position of the battery silicon wafer to prepare for the next storage of the battery silicon wafer. Repeating the above operation can realize the continuous insertion process. It should be noted that in order to further improve the stability of the insertion of the battery silicon wafers on the conveyor line 6 into the limit groove 35, a centering component can be set on the feed side of the basket assembly 3, and the cylinder in the centering component pushes the centering plate, so that the centering plates on both sides of the conveyor line 6 can adjust the position of the battery silicon wafers to achieve more accurate insertion positioning.

[0026] Reference Figure 1 , Figure 6 and Figure 7The inserting device also includes two groups of positioning components 7, which include an adjusting plate 71, on which a plurality of guide columns 72 are fixedly mounted, and the guide columns 72 are slidably connected to the fixing frame 13, and an elastic member 74 is mounted on the guide column 72, one end of the elastic member 74 is fixedly connected to the fixing frame 13, and the other end is fixedly connected to the adjusting plate 71, and a second limiting column 75 is fixedly mounted on the adjusting plate 71, which is used to position the battery silicon wafer during grabbing to reduce the risk of movement of the battery silicon wafer, and an adjusting column 73 is fixedly mounted on the adjusting plate 71, and the positions of the two adjusting columns 73 correspond to the first tilting block 56 and the second tilting block 57 respectively. When the adjusting column 73 and the adjusting plate 71 are only acted upon by the elastic member 74, there is a set spacing between the adjusting column 73 and the feeding end of the fixing plate 31, and the spacing is equal to the width of the first tilting block 56 or the second tilting block 57.

[0027] The inserting device also includes a grabbing robot 8, which includes a robotic arm and a number of receiving plates 81 fixedly installed at the output end of the robotic arm. The spacing between the several receiving plates 81 is equal to the spacing between the limiting grooves 35, thereby ensuring that the several receiving plates 81 can be smoothly inserted into the limiting grooves 35 and are distributed alternately with the battery silicon wafers after the insertion. An adsorption plate 82 is provided on the upper surface of the receiving plate 81, and the adsorption plate 82 is connected to the pressure supply system. The robotic arm drives the receiving plate 81 to insert into the lower side of the corresponding battery silicon wafer, and then rises a set distance to make the receiving plate 81 contact with the bottom of the battery silicon wafer. The pressure supply system provides negative pressure suction for the adsorption plate 82, thereby stably adsorbing the battery silicon wafer on the receiving plate 81 to avoid falling off during the transfer process, thereby realizing a group of battery silicon wafers in batches without transferring the flower basket.

[0028] It should be noted that when the grabbing robot 8 places the battery silicon wafer into the solution tank of the next process, when the grabbing robot 8 cannot obtain the precise positioning of the battery silicon wafer in the conveying direction of the basket assembly 3, it will cause the grabbing robot 8 to be unable to accurately control the distance between the bottom end of the transferred battery silicon wafer and the bottom of the solution tank of the next process, which will cause the battery silicon wafer to have a certain distance from the bottom of the solution tank when the grabbing robot 8 places the battery silicon wafer, making it impossible to achieve one-step positioning of the battery silicon wafer in the solution tank, and the battery silicon wafer will have a free fall process, which may damage the battery silicon wafer. The risk of, when the grasping robot 8 continues to descend to make the battery silicon wafer contact with the bottom of the solution tank, the battery silicon wafer with a relatively large elongation will contact the bottom first, and then the battery silicon wafer will move upward relative to the grasping robot 8, which may easily cause damage to the battery silicon wafer. The present invention limits and flattens one end of the battery silicon wafer of the insert by the second limiting column 75 before the grasping robot 8 grasps it, and cooperates with the grasping robot 8 to push up and grasp it in the opposite direction, thereby achieving precise control of the position uniformity of the battery silicon wafer and effectively reducing the difficulty of positioning operation in subsequent processing.

[0029] Working principle: For the convenience of description Figure 1 The conveyor line 6 and the flower basket assembly 3 near the left side are recorded as the first conveyor line 6 and the first flower basket assembly 3, and the ones on the right side are recorded as the second conveyor line 6 and the second flower basket assembly 3. The first conveyor line 6 is working, and the second conveyor line 6 is stopped. The first limiting column 43 on the first flower basket assembly 3 is in a limiting state. After the battery silicon wafer on the first conveyor line 6 is conveyed into the limiting groove 35 on the first flower basket assembly 3, the detection signal of the photoelectric sensor 9 is switched from the blocking state to the detectable state. The electric slide 2 drives the first conveyor line 6 to rise a set distance, that is, the distance between the two limiting grooves 35. The battery silicon wafer moves up driven by the limiting groove 35, and the above process is repeated, thereby continuously inserting the plurality of limiting grooves 35 of the first flower basket assembly 3 until the battery silicon wafer is inserted into the bottom limiting groove 35.

[0030] The first flower basket assembly 3 continues to move upward. At this time, the connecting column 45 is inserted into the limiting hole 55 of the first gear 52. The limiting plate 14 does not separate from the positioning hole 37 and the positioning groove 44. The first flower basket assembly 3 continues to move upward until the limiting plate 14 separates from the positioning hole 37 and the positioning groove 44. The output shaft of the motor 51 drives the second gear 54 to rotate counterclockwise. Through meshing transmission, the rack 59 and the adjusting frame 53 move leftward and the first gear 52 rotates counterclockwise. The first gear 52 drives the connecting column 45 and the first gear 52 inserted therein. The support column 41 rotates counterclockwise, and the first limiting column 43 rotates out of the limiting position, so that the discharge side of a basket assembly 3 is in an open state. When the rack 59 and the adjusting frame 53 move to the left, the second tilting block 57 pushes the adjusting column 73 corresponding to the basket assembly 3, so that the second limiting column 75 moves and is close to the feed side limiting position of the fixing plate 31 of the basket assembly 3. At this time, the elastic member 74 is in a stretched state. During the movement of the second limiting column 75, the offset battery silicon wafer can be initially pushed up.

[0031] The grabbing robot 8 drives the receiving plate 81 to be inserted between the battery silicon wafers, and at the same time pushes up several battery silicon wafers so that one end of them contacts the second limiting column 75, thereby realizing precise positioning of the ends of several battery silicon wafers. The receiving plate 81 moves up and adsorbs the corresponding battery silicon wafers. The adsorbed battery silicon wafers are transferred to the next process under the action of the grabbing robot 8.

[0032] After unloading is completed, the output shaft of the motor 51 controls the second gear 54 to rotate and reset, and the first limit column 43 is reset to the limit position. After the second tilting block 57 is separated from the adjusting column 73, the adjusting column 73 is away from the feeding end of a flower basket assembly 3 and reset under the action of the elastic member 74. The electric slide 2 drives the flower basket assembly 3 to descend, and the limit plate 14 is first inserted into the positioning hole 37 and the positioning groove 44 to keep the first limit column 43 stably limited. When the flower basket assembly 3 continues to descend, the connecting column 45 is separated from the limit hole 55 of the first gear 52, and the flower basket assembly 3 continues to descend until the uppermost limit groove 35 is in the insert position.

[0033] When inserting the battery silicon wafer into the limiting groove 35 at the bottom of the first basket assembly 3, the first conveyor line 6 stops working, and the second basket assembly 3 and the second conveyor line 6 start working to insert the wafer synchronously. The insertion and unloading principles of the second basket assembly 3 are different from those of the first basket assembly 3 only in that the initial rotation direction of the motor 51 is different, which will not be elaborated here. It should be noted that before the connecting column 45 corresponding to the first basket assembly 3 is not separated from the first gear 52, the connecting column 45 corresponding to the second basket assembly 3 is not in contact with the second gear 54 to avoid collision interference.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
