Description

Technical Field

[0001] This application belongs to the field of battery cell electroplating technology, and in particular relates to a blue film material transfer mechanism. Background Technology

[0002] Metallization is a crucial step in solar cell production. Currently, the main metallization methods include screen printing and electroplating. Screen printing requires silver paste, which is costly, and the printing process requires sintering to form grid lines, making the process complex. Therefore, using electroplating technology to construct low-cost metal grid lines, reduce costs and increase efficiency, has become the mainstream development trend in the industry.

[0003] When using electroplating technology to construct grid lines, the first step in the industry is to clean and inspect the surface of the blue film to be plated, ensuring it is clean and undamaged. Cleaning typically employs a chain cleaning machine, which usually consists of conveyor rollers and a cleaning solution with the liquid level slightly below the top of the rollers. As the conveyor rollers rotate, they move the blue film they carry. The rotation of the rollers causes the cleaning solution to ripple, and these waves contact the lower surface of the blue film. The surface tension helps to spread across the lower surface, cleaning it. Therefore, in the cleaning process, the surface of the blue film to be plated faces downwards. For quality inspection, a CCD camera suspended by a gantry is typically used to acquire image information of the surface of the blue film to be plated. This image information is then sent to an electronic inspection system for quality control. Since the CCD camera can also capture images of the upper surface of the blue film, in the quality inspection process, the surface of the blue film to be plated faces upwards.

[0004] Therefore, the blue film usually needs to be flipped between the cleaning and quality inspection processes to change the orientation of the surface to be coated. Currently, the commonly used methods in the industry are manual flipping or robotic flipping, but these methods have many problems:

[0005] (1) Manual material turning is inefficient and labor-intensive. Robotic arms can only turn one piece of material at a time. Although the frequency of action is higher than that of manual labor, the overall material turning efficiency is not high.

[0006] (2) Both the cleaning process and the quality inspection process have multiple parallel loading and unloading positions to ensure the production capacity of the process. However, the gaps between the loading positions are narrow, which is not suitable for adding personnel or robots. In addition, sometimes in order to adapt to the layout of other structures in the factory, the loading positions of the cleaning process and the quality inspection process are not one-to-one, and may only be partially corresponding. This further increases the difficulty of flipping and transferring the material and reduces production efficiency. Summary of the Invention

[0036] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0037] Reference Attachment Figure 1-3 This embodiment provides a blue film conveying mechanism, which includes a flipping support 1, a flipping shaft 2, a flipping disc 3, and a flipping motor 4. The flipping shaft 2 is horizontally arranged, with a set of flipping supports 1 rotatably connected to each end. The flipping disc 3 is coaxially sleeved on the flipping shaft 2, and several discs are distributed along the axial direction of the flipping shaft 2. The output shaft of the flipping motor 4 is connected to the flipping shaft 2 and is used to drive the flipping shaft 2 and the flipping disc 3 to rotate around their own axis. The flipping disc 3 is provided with a material receiving groove 3-1 recessed from its outer edge toward the axis.

[0038] When using the flipping mechanism provided in this application, the two sides of the flipping disc 3 are respectively connected to the unloading position of the cleaning system and the loading position of the quality inspection system. Initially, the sheet receiving groove 3-1 is horizontal and its opening faces the unloading position of the cleaning system to receive the sheet from the unloading position of the cleaning system. When the sheet is inserted into the sheet receiving groove 3-1, the flipping motor 4 starts, and the flipping shaft 2 and the flipping disc 3 rotate synchronously by 180°, which flips the sheet so that the surface to be plated changes from facing down to facing up. Finally, the sheet falls onto the loading position of the quality inspection system and is taken away. By using the above-mentioned blue film sheet transfer mechanism, sheets can be flipped and transferred in batches between the cleaning system and the quality inspection system, improving the efficiency of flipping and transferring.

[0039] Typically, both the unloading position of the cleaning system and the loading position of the quality inspection system employ a synchronous belt-synchronous wheel conveyor mechanism. The base of this mechanism may be a wide base with a width slightly smaller than the side length of the material sheet, or it may consist of two parallel, spaced, slender bases. Therefore, the number and placement of the tilting discs 3 on the tilting shaft 2 can be configured according to the aforementioned practical situation. Specifically, one tilting disc 3 can be placed on each side of each wide base, or one can be inserted between two slender bases to smoothly receive the material sheet. In the former case, the number of tilting discs 3 is twice the number of unloading positions; in the latter case, the number of tilting discs 3 is equal to the number of unloading positions. When the number of tilting discs 3 is equal to the number of unloading positions, the thickness of the tilting discs 3 can be appropriately increased as needed to increase the contact area between the material sheet receiving groove 3-1 and the material sheet, thereby improving stability.

[0040] Generally, to prevent material shortages in downstream processes, the capacity of upstream processes will be greater than or equal to that of downstream processes. That is, the number of unloading positions in the cleaning system will be greater than or equal to the number of loading positions in the quality inspection system. When the number of unloading positions in the cleaning system is greater than the number of loading positions in the quality inspection system, their positions will not correspond perfectly. When the number of unloading positions in the cleaning system is equal to the number of loading positions in the quality inspection system, their positions may correspond perfectly or not (due to limitations imposed by the layout design within the plant).

[0041] When the unloading positions of the cleaning system and the loading positions of the quality inspection system correspond perfectly, the flipping mechanism provided by the above technical solution can be directly used for flipping and transferring materials. When the unloading positions of the cleaning system and the loading positions of the quality inspection system do not correspond perfectly, a flipping disc 3 with the same number and position as the loading positions of the quality inspection system can be set in this flipping mechanism. Several sets of first feeders 5, several sets of second feeders 6, and a scheduling component 10 are set at the input end of the flipping disc 3 (i.e., the end closer to the upstream process). The first feeders 5 The first conveyor 5 and the second conveyor 6 are arranged side by side and the conveying direction of both is perpendicular to the turning shaft 2, that is, parallel to the unloading direction of the cleaning system. The conveying direction of the scheduling component 10 is parallel to the turning shaft 2, that is, perpendicular to the unloading direction of the cleaning system. Among them, the first conveyor 5 and the turning disk 3 have the same number and corresponding positions. It is used to directly transfer the material to the material receiving groove 3-1. The second conveyor 6 is used to dock with the unloading position of the cleaning system and receive the material. The scheduling component 10 is used to schedule the material on the second conveyor 6 to the first conveyor 5.

[0042] If there are no corresponding positions in the cleaning system and the quality inspection system, the number of second feeders 6 is the same as the number of unloading positions in the cleaning system. If there are some corresponding positions in the cleaning system and the quality inspection system, the sum of the number of first feeders 5 and second feeders 6 is less than the sum of the number of positions in the cleaning system and the quality inspection system. Some of the first feeders 5 correspond to both the unloading positions in the cleaning system and the loading positions in the quality inspection system, thus serving the dual functions of directly receiving materials from the cleaning system and directly transferring materials to the material receiving tank 3-1.

[0043] To illustrate this clearly, this application uses the case where the number of unloading positions in the cleaning system and the number of loading positions in the quality inspection system are equal, but only a portion of the positions correspond one-to-one as an example. Let the number of unloading positions in the cleaning system equal the number of loading positions in the quality inspection system, and let y be the number of positions that correspond one-to-one between the cleaning system and the quality inspection system. If y < x, then the positions in the cleaning system and the quality inspection system are misaligned, and the number of misaligned positions is xy. Therefore, the number of first conveyors 5 + the number of second conveyors 6 = 2x - y. Let the first feeder 5 directly corresponding to the unloading position of the cleaning system be the first feeder A5-1, and the other first feeders 5 be the first feeders B5-2. When the unloading position of the cleaning system receives material, the first feeder A5-1 and the second feeder 6 directly receive the material pieces. The scheduling component 10 is activated to transfer the material pieces on the second feeder 6 to the first feeder B5-2. Then, the first feeders A5-1 and B5-2 respectively transfer the material pieces to the turning plate 3, so that each turning plate 3 located on the same turning shaft 2 receives material. The turning motor 4 is started, so that each turning plate 3 flips the material pieces in a group and transfers them to the loading position of the quality inspection system. When the material pieces are taken away for quality inspection, the turning plate 3 continues to rotate, so that the empty material piece receiving groove 3-1 returns to the side of the cleaning system to start the next cycle of turning and transferring.

[0044] By adopting the above technical solution, the problem of low material turning and conveying efficiency caused by the mismatch between the positions of the cleaning system and the quality inspection system due to equipment layout issues can be solved. By adjusting the conveying speed and conveying path length of the first conveyor 5 and the second conveyor 6, as well as the rotation speed of the turning plate 3, the material conveying time difference between the mechanisms can be balanced, so that the material pieces can be conveyed in an orderly and efficient manner. For example, the material transfer speed can be controlled such that the first material feeder A5-1 < the first material feeder B5-2, which can compensate for the time spent by the scheduling component 10 transferring the material sheet from the second material feeder 6 to the first material feeder B5-2, so that the first material feeder A5-1 and the first material feeder B5-2 can transfer the same group of material sheets to the turning plate 3 at the same time; the material transfer speed can also be controlled such that the second material feeder 6 < the first material feeder A5-1, which can compensate for the time spent by the scheduling component 10 returning from the first material feeder B5-2 to the second material feeder 6, so that the scheduling component 10 has enough time to return to the second material feeder 6 to absorb and move the newly transferred material sheet.

[0045] Of course, when the unloading position of the cleaning system is greater than the loading position of the quality inspection system, the above method can also be used to schedule, flip and transfer the material pieces. Increasing the number of second feeders 6, adjusting the material transfer speed and material transfer path length of the first feeder 5 and the second feeder 6, and the rotation speed of the flipping plate 3 can balance the material transfer time difference between the mechanisms, so that the material pieces are transferred in an orderly and efficient manner. The principle is similar to that above, and will not be repeated here.

[0046] Reference Attachment Figure 3The scheduling component 10 in this application includes a scheduling base frame 10-1, a scheduling suction cup 10-2, and a scheduling driver 10-3. The two ends of the scheduling base frame 10-1 are respectively mounted on the outermost first feeder 5 and the outermost second feeder 6. The scheduling suction cup 10-2 is slidably connected to the scheduling base frame 10-1. The scheduling driver 10-3 is used to drive the scheduling suction cup 10-2 to move along the scheduling base frame 10-1. When material arrives at the cleaning system, the scheduling driver 10-3 moves the scheduling suction cup 10-2 to the second feeder 6 to pick up the material sheet, and then moves the scheduling suction cup 10-2 to the first feeder B5-2 to dispose of the material sheet.

[0047] The scheduling suction cup 10-2 can be a vacuum suction cup commonly used in this field, which picks up materials when vacuuming and releases materials when vacuuming is broken; the scheduling driver 10-3 can be a linearly telescopic device, such as a cylinder, hydraulic rod, electric telescopic rod, etc., whose telescopic direction is consistent with the extension direction of the scheduling base 10-1. Alternatively, a servo motor can be used in conjunction with a synchronous pulley, synchronous belt, etc. For example, a synchronous pulley and synchronous belt can be arranged along the extension direction of the scheduling base 10-1, and the scheduling suction cup 10-2 can be connected to the synchronous belt. When the servo motor drives the synchronous pulley to rotate, the scheduling suction cup 10-2 moves together with the synchronous belt.

[0048] Considering that the scheduling suction cup 10-2 itself has a large mass, directly connecting it to the scheduling driver 10-3 would generate downward torque and accelerate the wear of the scheduling driver 10-3. Therefore, in this embodiment, a linear guide rail is also provided on the scheduling base 10-1. The linear guide rail is equipped with a guide rail 10-4 and a moving part 10-5. The guide rail 10-4 extends in the same direction as the scheduling base 10-1, the moving part 10-5 is connected to the scheduling driver 10-3, and the scheduling suction cup 10-2 is connected to the moving part 10-5 through the scheduling lifting cylinder 10-6. The movable component 10-5 carries the scheduling suction cup 10-2, and the guide rail 10-4 supports the movable component 10-5, reducing the downward torque generated by the movable component 10-5 and the scheduling suction cup 10-2 on the scheduling driver 10-3, thus improving the service life of the equipment. In addition, the added scheduling lifting cylinder 10-6 can change the height of the scheduling suction cup 10-2, preventing the bottom of the scheduling suction cup 10-2 from colliding with other structural components when it moves along the scheduling base frame 10-1. When the cleaning system receives material, the dispatching driver 10-3 moves the dispatching suction cup 10-2 to the second feeder 6, the piston rod of the dispatching lifting cylinder 10-6 extends, and the dispatching suction cup 10-2 is lowered to pick up the material piece; then, the piston rod of the dispatching lifting cylinder 10-6 retracts to lift the dispatching suction cup 10-2 and the material piece it has picked up, and the dispatching driver 10-3 moves the dispatching suction cup 10-2 and the material piece to the first feeder B5-2; then, the piston rod of the dispatching lifting cylinder 10-6 extends, and the dispatching suction cup 10-2 is lowered to place the material piece; finally, the piston rod of the dispatching lifting cylinder 10-6 retracts to lift the dispatching suction cup 10-2, and the dispatching driver 10-3 moves the dispatching suction cup 10-2 to the second feeder 6 for the next material dispatching.

[0049] When the number of unloading positions in the cleaning system and the number of loading positions in the quality inspection system are equal, the number of scheduling suction cups 10-2 and the number of second feeders 6 are the same. In order to save consumables and operating costs and improve material transfer efficiency, a mounting plate 10-7 can be set on the moving part 10-5, and multiple scheduling lifting cylinders 10-6 can be installed side by side on the mounting plate 10-7. A set of scheduling suction cups 10-2 can be installed at the bottom of each scheduling lifting cylinder 10-6.

[0050] In addition, a position sensor 11 can be provided at the output end of the first feeder 5. The position sensor 11 can detect whether each output end of the first feeder 5 is carrying a piece of material, so as to control the start and stop of the turning motor 4. When the piece of material on the second feeder 6 is transferred to the first feeder B5-2 and is synchronously transferred to the turning plate 3 with the piece of material on the first feeder A5-1, all the pieces of the same group are in position and are sensed by the position sensor 11. Then the turning motor 4 starts and controls the turning plate 3 to flip a group of pieces of material.

[0051] Similar to the unloading position of the cleaning system and the loading position of the quality inspection system, the first feeder 5 and the second feeder 6 in this application can both be synchronous belt-synchronous wheel type conveyor mechanisms, configured as follows: a base 7, a synchronous belt-synchronous wheel module 8, and a feeder motor 9. The synchronous belt-synchronous wheel module 8 is mounted on the base 7 and is driven by the feeder motor 9. The base 7 can be a wide base with a width slightly smaller than the side length of the wafer, or it can be two parallel, spaced, slender bases. The number and placement of the tilting discs 3 on the tilting shaft 2 can be configured according to the actual situation described above. Similar technical solutions have been described in detail above and will not be repeated here. The position sensor 11 used in this application to detect the position of the silicon wafer can be an existing device such as an infrared sensor or a photoelectric sensor.

[0052] To improve the efficiency of material turning and conveying, in this application, multiple material receiving grooves 3-1 are evenly distributed along the circumference of the turning plate 3. When a set of material receiving grooves 3-1 on the turning plate 3 is unloading, the material receiving grooves 3-1 opposite to it can be used to receive material. When the thickness of the turning plate 3 is large, several weight reduction holes 3-2 can be provided on the turning plate 3. The weight reduction holes 3-2 are evenly distributed between adjacent material receiving grooves 3-1 to reduce the driving load.

[0053] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting multiple flipping discs 3 between upstream and downstream processes and operating synchronously, the material pieces are flipped and transferred in batches, thereby improving the efficiency of flipping and transferring materials; by using the first feeder 5, the second feeder 6 and the scheduling component 10, the material pieces are scheduled and transferred in groups, thereby solving the problem of low material transfer efficiency caused by the incomplete correspondence of material positions between upstream and downstream processes.

[0054] The embodiments of this application have been described in detail above. These descriptions are merely preferred embodiments and should not be construed as limiting the scope of this application. All equivalent variations and modifications made within the scope of this application should still fall within the patent coverage of this application.
