Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor device processing and conveying, and more specifically to a photovoltaic cell piece anti-deviating continuous feeding structure. Background Art

[0002] With the popularization of automated production in the photovoltaic manufacturing industry, most photovoltaic cell production and processing processes use fully automatic string welding machines to implement the welding process. During the welding process, the loading part is required to transport the cells to the welding station.

[0003] The traditional cell loading system includes a loading conveyor line and a cell transport mechanism arranged at the end of the loading conveyor line. For example, patent No. CN109244013A discloses an automatic tidying device for photovoltaic cells. The two adsorption mechanisms in the present invention can work simultaneously. While completing the loading and tidying of one cell, the previous cell that has been tidyed can be sent to the next workstation.

[0004] However, one of the adsorption mechanisms in the above patent content grabs one battery cell from the battery cell stacking and installation unit each time, moves it vertically first and then horizontally to transport it to the sorting platform, and uses the sorting platform to sort the battery cells. This process is carried out separately before and after the loading and sorting processes. After completing the loading of one battery cell, the upper group of adsorption mechanisms goes to the battery cell stacking and installation unit to grab another battery cell. After the next group of adsorption mechanisms completes the sorting process, the sorted battery cells are adsorbed from the sorting platform to the next operating station. This not only increases mechanical tooling, but also makes the process cumbersome, and there are certain production disadvantages.

[0005] To this end, we propose a photovoltaic cell anti-deviation continuous feeding structure to address the defects of the existing technology. Summary of the invention

[0006] The purpose of the present invention is to solve the problem in the prior art that the loading and regularization processes need to be carried out separately, resulting in cumbersome processes. A photovoltaic cell anti-deviation continuous loading structure is provided, which is an improvement on the traditional loading structure, so that the centering and regularization of the cell can be completed during the continuous loading process. There is no need to use an additional regularization structure for subsequent deviation correction, which simplifies the process and improves work efficiency.

[0009] A deflection correction suction frame is slidably installed on the welding table, and a power mechanism for driving the deflection correction suction frame in horizontal and vertical directions is installed at the bottom end of the welding table. A deflection correction groove for negative pressure suction of the end of the battery cell is provided on the lower end wall of the deflection correction suction frame, and a plurality of suction disks are embedded and installed on the top wall of the deflection correction groove. The tops of the plurality of suction disks are commonly connected to a vacuum generator installed on the upper end of the deflection correction suction frame, and regular inclined surfaces inclined and expanded outward are provided on the inner walls on both sides of the deflection correction groove, and a plurality of deflection correction guide rollers rotatably installed from the outside to the inside are provided on the regular inclined surfaces.

[0010] Furthermore, the conveying rack is a U-shaped structure with an opening facing downward. The lower ends of multiple conveying racks pass through the loading platform and are connected front and back through a connecting plate. A conveying groove that passes through the connecting plate up and down is opened on the loading platform, and an interlocking cavity that is used to place the silo and passes through up and down is opened in the middle of the conveying rack.

[0011] Furthermore, the driving mechanism includes screws rotatably installed on the left and right sides of the loading platform respectively, the other ends of a pair of screws pass through a connecting plate and rotate on the end wall on the other side of the loading platform, the screws are connected with a threaded sleeve of the connecting plate, and a driving motor for synchronously rotating and driving a pair of screws is fixedly installed at the front end of the loading platform.

[0012] Furthermore, the lifting structure includes a pair of lifting cylinders installed below the loading station, and a lifting platform that is movable and penetrates the interlocking cavity is fixed at the telescopic end of the pair of lifting cylinders.

[0013] Furthermore, the silo has a plurality of partitions evenly distributed in the vertical direction, a loading space for placing battery cells is formed between two adjacent partitions, and a plurality of discharge ports corresponding to the loading space are opened in the vertical direction on the end wall of the silo facing the welding table.

[0014] Furthermore, a plurality of discharge areas are spaced apart on the welding table, the central axis of the deviation correcting and suction frame is on the same vertical plane as the central axis of the discharge area, movable columns are provided on both sides of the lower end of the deviation correcting and suction frame and respectively penetrate the two sides of the welding table, and a conveying groove 2 for the horizontal sliding of the movable column is provided on the welding table.

[0015] Furthermore, the power mechanism includes a pair of electric guide rails located at the lower end of the welding table and fixedly installed thereon, and a moving seat fixedly connected to the bottom ends of a pair of moving columns is installed on the pair of electric guide rails, and two lifting cylinders for lifting and lowering the moving columns in the vertical direction are embedded on both sides of the interior of the moving seat.

[0016] Furthermore, the outer diameters of the plurality of deflection correcting guide rollers decrease from the outside to the inside, and the outer end walls of the plurality of deflection correcting guide rollers gradually approach the straight edge of the deflection correcting groove from the outside to the inside.

[0017] Optionally, a rotating shaft is rotatably installed on one side of the outer end of the welding table through a bracket, and a driving motor 2 for rotationally driving the rotating shaft is fixed at the end of the bracket.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) This solution is to set up a hopper on the loading table for stacking multiple battery cells and capable of moving horizontally and vertically. The correction suction rack is used to move back and forth left and right to realize the continuous loading of multiple battery cells in the hopper onto the welding table one by one. When the correction suction rack is pushed close to the hopper, the end of the battery cell is pushed into the correction groove, and the multiple correction guide rollers on both sides of the correction groove are used to make the battery cell move toward the centering direction of the correction groove. Then, the suction plate is used to perform negative pressure suction on the upper end wall of the battery cell to complete the positioning of the battery cell. Finally, the positioned and sucked battery cell is directly transported to the discharge area of ​​the welding table, so that the centering and regularization of the battery cell can be completed during the continuous loading process. There is no need to use an additional regularization structure for correction processing later, which simplifies the process and improves work efficiency.

[0020] (2) This scheme also optimizes the design of the correcting guide roller. The outer diameters of the multiple correcting grooves decrease from the outside to the inside, and the outer end walls of the multiple correcting grooves gradually approach the side edges of the correcting grooves from the outside to the inside. The two sides of the correcting grooves are tilted and expanded outward to expand the outer ports of the correcting grooves. This makes it easier for the battery cells to enter the correcting grooves smoothly when the correcting suction frame is pushed toward one side of the battery cell. The battery cells are gradually pushed toward the center line of the correcting grooves from the outside to the inside, thereby further improving the guiding and correcting effect.

[0037] The following will combine 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 the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0038] Example 1: The present invention discloses a photovoltaic cell anti-deviating continuous feeding structure, please refer to Figure 1 , Figure 2 , including a loading table 1 arranged near the welding tool 7 and a welding table 8 installed on the welding tool 7 and arranged vertically with the loading table 1. A plurality of conveying racks 2 are horizontally conveyed along the front and rear directions by a driving mechanism on the loading table 1. A silo 5 for stacking and loading a plurality of battery cells 6 is placed on the conveying racks 2. The middle part of the loading table 1 corresponding to the end position of the welding table 8 is a loading station.

[0039] See also Figure 3 The conveying frame 2 is a U-shaped structure with an opening facing downward. The lower ends of multiple conveying frames 2 pass through the loading platform 1 and are connected front and back through a connecting plate. A conveying groove 101 for the connecting plate to pass through the upper and lower parts is provided on the loading platform 1. The driving mechanism includes screws 3 that are rotatably installed on the left and right sides of the loading platform 1 respectively. The other ends of a pair of screws 3 pass through the connecting plate and rotate on the end wall on the other side of the loading platform 1. The screws 3 are connected with the threaded sleeve of the connecting plate. A driving motor 4 for synchronously rotating and driving a pair of screws 3 is fixedly installed at the front end of the loading platform 1. By starting the driving motor 4, multiple conveying frames 2 can be moved forward or backward in the horizontal direction, and the bins 5 loaded with battery cells 6 can be transported to the loading station one by one.

[0040] A loading cavity is provided at the loading station, which runs through the loading cavity. A lifting structure is installed at the bottom of the loading platform 1, which runs through the loading cavity and is used to drive the material bin 5 to lift and lower. A fitting cavity 201 is provided in the middle of the conveying frame 2, which is used to place the material bin 5 and runs through the material bin 5. The lifting structure includes a pair of lifting cylinders 103 installed below the loading station, and a lifting platform 102 is fixed at the telescopic end of the pair of lifting cylinders 103, which is movable and runs through the fitting cavity 201.

[0041] See also Figure 3-Figure 5 The silo 5 has a plurality of partitions 501 evenly distributed along the vertical direction, and a loading space for placing the battery cells 6 is formed between two adjacent partitions 501, and a plurality of discharge ports 502 corresponding to the loading space are opened along the vertical direction on the end wall of the silo 5 facing the welding table 8.

[0042] In the initial state, the lifting platform 102 retreats to the loading chamber without affecting the horizontal movement of the conveyor frame 2. When loading, the battery cell 6 is lifted layer by layer from bottom to top by driving the lifting cylinder 103 upward. A correction suction frame 9 that moves horizontally left and right is slidably installed on the welding table 8 to facilitate the use of the correction suction frame 9 to clamp and convey the battery cell 6 lifted to a suitable position outward.

[0043] See also Figure 1 and Figure 6 A power mechanism for driving the correcting suction frame 9 in horizontal and vertical directions is installed at the bottom end of the welding table 8. The power mechanism includes a pair of electric guide rails 10 located at the lower end of the welding table 8 and fixedly installed thereon. A moving seat 11 fixedly connected to the bottom end of a pair of moving columns 903 is installed on the pair of electric guide rails 10. Two lifting cylinders for lifting and lowering the moving columns 903 in the vertical direction are embedded on both sides of the moving seat 11. The correcting suction frame 9 is used to reciprocate left and right to realize the continuous loading of multiple battery cells 6 in the silo 5 onto the welding table 8 one by one. The correcting suction frame 9 is used to reciprocate left and right to realize the continuous loading of multiple battery cells 6 in the silo 5 onto the welding table 8 one by one.

[0044] See also Figure 6-Figure 11 The lower end wall of the deflection correction suction rack 9 is provided with a deflection correction groove 901 for negative pressure suction of the end of the battery cell 6, and a plurality of suction discs 902 are embedded in the top wall of the deflection correction groove 901. The tops of the plurality of suction discs 902 are commonly connected to a vacuum generator 12 installed on the upper end of the deflection correction suction rack 9. A plurality of discharge areas 801 are distributed at intervals on the welding table 8. The central axis of the deflection correction suction rack 9 and the central axis of the discharge area 801 are on the same vertical plane. Both sides of the lower end of the deflection correction suction rack 9 are provided with moving columns 903 respectively penetrating to both sides of the welding table 8. A conveying groove 2 802 for horizontal sliding of the moving column 903 is provided on the welding table 8;

[0045] During the process of pushing the deflection correction suction rack 9 close to the silo 5, the end of the battery cell 6 on the same horizontal plane is pushed into the deflection correction groove 901. The width of the deflection correction groove 901 is consistent with the width of the battery cell 6. The deflection correction groove 901 is used to guide and regularize the battery cell 6 until the end of the deflection correction suction rack 9 contacts the end of the discharge port 502, and the end of the battery cell 6 contacts the inner end wall of the deflection correction groove 901. Then, the vacuum generator 12 is started, and multiple suction plates 902 are used to perform negative pressure suction on the outer end of the battery cell 6 to complete the positioning. Finally, the positioned and sucked battery cell 6 is transported to the discharge area 801 of the welding table 8 through the electric guide rail 10 and the lifting cylinder 2 in the moving seat 11. This reciprocating cycle is repeated to complete the transportation of multiple battery cells 6 one by one to the discharge area 801 at the preset position.

[0046] Embodiment 2: Based on Embodiment 1, this embodiment further improves the internal structure of the deviation correction suction frame 9 to improve the accuracy of pushing and positioning the battery cell 6, as follows;

[0047] See also Figure 7-Figure 9 as well as Fig.12 The inner walls of both sides of the deflection correction groove 901 are provided with regular inclined surfaces that are inclined and expanded outward, and a plurality of deflection correction guide rollers 904 are rotatably installed from the outside to the inside on the regular inclined surfaces. The outer diameters of the plurality of deflection correction guide rollers 904 decrease from the outside to the inside, and the outer end walls of the plurality of deflection correction guide rollers 904 gradually approach the side edge of the deflection correction groove 901 from the outside to the inside;

[0048] The width of the loading space of the silo 5 is slightly larger than the width of the battery cell 6, so that the battery cell 6 can be quickly loaded into the loading space through the discharge port 502. The original width of the correction groove 901 is consistent with the width of the battery cell 6. Regular inclined surfaces that are inclined and expanded outward are provided on the inner walls of both sides of the correction groove 901. The two sides of the correction groove 901 are inclined and expanded outward, so that only the innermost width of the correction groove 901 is consistent with the width of the battery cell 6. The outer port of the correction groove 901 is enlarged, so that when the correction suction rack 9 is pushed toward the side of the battery cell 6, the battery cell 6 can smoothly enter the correction groove 901;

[0049] By adding multiple deflection correction guide rollers 904, when the battery cell 6 is pushed into the deflection correction groove 901, the multiple deflection correction guide rollers 904 rotate, which, on the one hand, reduces the friction between the side end wall of the battery cell 6 and the inner wall of the deflection correction groove 901, and on the other hand, the outer end walls of the multiple deflection correction guide rollers 904 gradually approach the straight edge of the deflection correction groove 901 from the outside to the inside, that is, the outer end walls of the multiple deflection correction guide rollers 904 gradually approach the end wall of the battery cell 6 moving along the centering line of the deflection correction groove 901 from the outside to the inside, and gradually push the battery cell 6 along the centering direction of the deflection correction groove from the outside to the inside, thereby improving the deflection correction and regularization effect, completing the deflection correction and centering in the clamping and suction process, without the need for additional regularization structure for subsequent deflection correction processing, reducing mechanical tooling, occupying a small space, simplifying the process, and improving work efficiency.

[0050] Embodiment 3: Based on Embodiments 1 and 2, this embodiment optimizes the conveying track of the deviation correction and suction rack 9, as follows;

[0051] See also Fig.13 , Fig.14 , a rotating shaft 13 is rotatably mounted on one side of the outer end of the welding table 8 through a bracket, a driving motor 2 14 for rotating the rotating shaft 13 is fixed at the end of the bracket, and a plurality of flip sheets 15 corresponding to the positions of the discharge area 801 are evenly sleeved on the rotating shaft 13, and a laser receiver 16 is fixedly mounted on the end wall of the plurality of flip sheets 15 facing the side of the loading table 1, and a laser transmitter 17 adapted to the laser receiver 16 is fixedly mounted on the end wall of the movable column 903 located on the outside, and a plurality of flip sheets 15 correspond one by one to the end of each discharge area 801 close to the driving motor 2 14. When the plurality of battery cells 6 are placed one by one in the discharge area 801 from left to right by using the deviation correction suction rack 9;

[0052] The laser receiver 16 is flipped to the same horizontal line corresponding to the position by rotating the rotating shaft 13. For example, when the battery cell 6 is placed on the first discharge area 801 on the left, when the correction and suction frame 9 moves toward the first discharge area 801, the flip plate 15 is driven to flip by the driving motor 2 14, and the loading table 1 on the moving column 903 and the laser receiver 16 on the first flip plate 15 on the left are started. The laser receiving distance is compared with the preset distance. When the laser distance received by the laser receiver 16 from the loading table 1 reaches the preset distance, a stop motion signal is given to the electric guide rail 10 to improve the conveying accuracy of the correction and suction frame 9 to ensure that the correction and suction frame 9 accurately conveys the battery cell 6 to the first discharge area 801. Similarly, the precise discharge of multiple subsequent discharge areas 801 is completed to reduce errors.

[0053] When placing and positioning battery cells 6 of different length batches or adjusting the placement distance between two battery cells 6 is required, it is only necessary to pre-adjust the distance between each flip plate 15 and the corresponding material discharge area 801 .

[0054] In summary: by setting a vertically mounted loading table 1 and welding table 8, the welding table 8 is directly mounted on the welding fixture 7, the battery cells 6 for loading are pre-stacked and loaded in multiple silos 5, and the driving mechanism on the loading table 1 is used to successively transport the stacked multiple battery cells 6 to the loading station, and then the correction suction frame 9 is transported to the end of the silo 5 at the loading station through the power mechanism. In the process of pushing the correction suction frame 9 close to the silo 5, the end of the battery cell 6 on the same horizontal plane is pushed into the correction groove 901 to complete the centering positioning, and the suction plate 902 is used to complete the suction positioning, and then the power mechanism is used to transport the sucked battery cell 6 to the discharge area 801, completing one loading. In the subsequent cyclic loading process, the battery cell 6 below is lifted up layer by layer through the lifting structure so that the battery cell 6 corresponds to the position of the correction groove 901;

[0055] During the centering and positioning process of the correction suction frame 9 moving toward the end of the battery cell 6, a plurality of correction guide rollers 904 on both sides of the correction groove 901 are used to move the battery cell 6 toward the centering direction of the correction groove 901 until the end of the battery cell 6 touches the inner wall of the correction groove 901, and then the suction plate 902 is used to perform negative pressure suction on the upper end wall of the battery cell 6 to complete the correction and positioning of the battery cell 6, and finally the positioned and sucked battery cell 6 is transported to the discharge area 801 of the welding table 8, so that the battery cell can be aligned and adjusted into place at one time during the continuous loading process, without the need for subsequent use of additional regular structures for correction processing, thereby improving work efficiency.

[0056] The above 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 within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered by the protection scope of the present invention.
