Description

Technical Field

[0001] This application belongs to the field of battery cell electroplating technology, and in particular relates to a blue film feeding 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 industry utilizes a chuck to pick up the blue film and suspend it in the electroplating tank. Generally, to ensure uniform electroplating, the electroplating solution and electric field in the tank should be evenly distributed on the surface of the blue film to be plated. This requires, in addition to pre-adjusting the shape and position of the structures related to the distribution of the electroplating solution and electric field, that the blue film be accurately suspended in the area where the electroplating solution and electric field are evenly distributed. The accurate operation of the latter relies on two factors: first, the precise positioning of the chuck, which only requires changing the coordinate parameters in the programming control system and conducting on-site debugging before production; and second, ensuring the accurate original position and orientation of the blue film when the chuck picks it up.

[0004] Generally, the blue film is conveyed to the suction station of the chuck via a synchronous belt-synchronous wheel mechanism. Even with the assistance of a position sensor, it can only know whether the blue film is present at the suction station, but cannot know whether the center position and corner orientation of the blue film are accurate. Whether the chuck can pick up the blue film is not particularly related to the accuracy of the center position and corner orientation of the blue film. Only when there is a serious misalignment will the chuck fail to pick up the blue film. When the chuck can pick up the blue film, if the blue film is skewed, it may collide with the film, or there may be no area in the electroplating tank with a uniformly distributed electric field, resulting in uneven coating deposition and reduced production yield. Summary of the Invention

[0005] This application provides a blue film feeding mechanism for adjusting the center position and corner direction of the blue film, so that the blue film can be accurately transferred into the electroplating tank, reducing collisions, ensuring uniform coating, and improving production yield.

[0033] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0034] Reference Attachment Figure 1-4This embodiment proposes a blue diaphragm feeding mechanism, which includes: a base 100, a first feeding component 200, and a second feeding component 300. The base 100 can be the base of a synchronous belt-synchronous wheel mechanism for feeding blue diaphragms to save space. The base 100 is provided with a plurality of mounting cavities 110 with open tops. A plurality of first feeding components 200 are movably disposed in different mounting cavities 110, and their tops can extend out of the mounting cavities 110. A plurality of second feeding components 300 are movably disposed on the base 100 and are arranged in a ring with the first feeding components 200. The tops of the second feeding components 300 can move toward the center of the ring.

[0035] The first material handling assembly 200 and the second material handling assembly 300 are arranged in a ring. Their function is to push the blue diaphragm located in the ring by moving their respective top ends, thereby adjusting the center position and corner orientation of the blue diaphragm. Since the blue diaphragm needs to be pushed, the top ends of the first material handling assembly 200 and the second material handling assembly 300 are at least higher than the bottom surface of the blue diaphragm when pushing the diaphragm. The first material handling assembly 200 is movably mounted in the mounting cavity 110. When it does not need to push the diaphragm, it can be hidden in the mounting cavity 110. The blue diaphragm can be transmitted through the top surface of the mounting cavity 110 by the synchronous pulley-synchronous belt on the base 100. Therefore, the first material handling assembly 200 can be positioned in the transmission direction of the blue diaphragm, while the second material handling assembly 300 is positioned on other sides of the blue diaphragm.

[0036] The number and distribution order of the first material handling component 200 and the second material handling component 300 can be configured according to actual needs, and no specific restrictions are imposed here. For example, if the feeding mechanism of the blue diaphragm is a straight synchronous belt-synchronous wheel mechanism, then one of the first material handling components 200 can be set on one set of opposite sides of the blue diaphragm, and one of the second material handling components 300 can be set on the other set of opposite sides of the blue diaphragm; or if the feeding mechanism of the blue diaphragm is a right-angle turn synchronous belt-synchronous wheel mechanism, then one of the first material handling components 200 can be set on one set of adjacent sides of the blue diaphragm, and one of the second material handling components 300 can be set on the other set of adjacent sides of the blue diaphragm; or The feeding mechanism of the blue diaphragm is a T-shaped synchronous belt-synchronous wheel mechanism. A first feeding assembly 200 can be set on three adjacent sides of the blue diaphragm, and a second feeding assembly 300 can be set on the other side. That is, the number of first feeding assemblies 200 and second feeding assemblies 300 can be equal or unequal. The first feeding assemblies 200 and second feeding assemblies 300 can be alternately distributed, or several first feeding assemblies 200 can be distributed adjacently and several second feeding assemblies 300 can be distributed adjacently.

[0037] To facilitate the movement of the first material handling plate 220, the top of the side of the mounting cavity 110 near the center of the ring is provided with a slot that communicates with the opening on the top surface of the mounting cavity 110. That is, the opening on the top surface of the mounting cavity 110 first extends horizontally to the side, and then extends vertically downward on the side.

[0038] In this embodiment, the first material handling assembly 200 includes a first material handling cylinder 210, a first material handling plate 220, and a guide block 230. The first material handling cylinder 210 is vertically mounted in the mounting cavity 110, and its piston rod extends vertically. The guide block 230 is located at the top of its piston rod. The piston rod of the first material handling cylinder 210 can drive the guide block 230 to move up and down. The side of the guide block 230 is provided with a straight groove 231 extending laterally. The bottom end of the first material handling plate 220 is provided with a sliding member 240. The sliding member 240 is movably disposed in the straight groove 231 and can slide and rotate in the straight groove 231. The first material handling plate 220 is located in the mounting cavity 110 and is connected to the base 100 through the material handling plate pivot 250. The bottom end of the first material handling plate 220 is fixedly connected to the sliding member 240. When the first material handling cylinder 210 lifts the guide block 230 and drives the sliding component 240 to slide and rotate in the straight slot 231, the bottom height of the first material handling plate 220 changes. Due to the limiting effect of the material handling plate rotating shaft 250, the tilt angle of the first material handling plate 220 changes, causing the horizontal and vertical positions of the top of the first material handling plate 220 to change, and it switches between the non-material handling position and the material handling position, thereby realizing the pushing of the blue film.

[0039] In the non-feeding position, that is, when the piston rod of the first feeding cylinder 210 is not extended, the tilt direction of the first feeding plate 220 can be towards the center of the ring. The sliding member 240 is located at one end of the straight groove 231 near the center of the ring. When the piston rod of the first feeding cylinder 210 extends, the straight groove 231 moves upward, and the sliding member 240 slides and rotates to the other end of the straight groove 231. The first feeding plate 220 then rotates to the feeding position. At this time, the height of the top of the first feeding plate 220 decreases, and the lateral position gradually approaches the center of the ring, that is, the area where the blue film is located, thereby pushing the blue film.

[0040] Of course, when the material handling position is not reached, that is, when the piston rod of the first material handling cylinder 210 is not extended, the tilt direction of the first material handling plate 220 can also be opposite to the center of the ring. The sliding member 240 is set on the plate surface of the first material handling plate 220 near the first material handling cylinder 210, and the first material handling block 260 is set on the other plate surface of the first material handling plate 220. The sliding member 240 is located at one end of the straight groove 231 near the center of the ring. When the piston rod of the first material handling cylinder 210 extends, the straight groove 231 moves upward, and the sliding member 240 slides and rotates to the other end of the straight groove 231. The first material handling plate 220 rotates to the material handling position. At this time, the top height of the first material handling plate 220 increases, and the lateral position gradually approaches the center of the ring, driving the first material handling block 260 to approach the center of the ring, that is, the area where the blue film is located, thereby pushing the blue film.

[0041] The two configuration methods mentioned above can be selected according to actual usage requirements, which include, but are not limited to: the height difference between the top surface of the blue film adsorption station on the base 100 and the top of the mounting cavity 110, the material (structural strength and torsional strength differ) and size of each structure in the first material handling component 200.

[0042] In this embodiment, the sliding member 240 includes a U-shaped member 241 and a sliding rod 242. The first material handling plate 220 is located at the closed end of the U-shaped member 241, and the guide block 230 extends into the open end of the U-shaped member 241. The sliding rod 242 is movably inserted into the straight groove 231, and its end is fixedly connected to the open end of the U-shaped member 241. When the guide block 230 is raised, the sliding rod 242 slides from one end of the straight groove 231 to the other end. Due to the restriction of the first material handling plate 220 and the material handling plate pivot 250, the sliding rod 242 will also rotate. The U-shaped member 241 provided in this embodiment can rotate accordingly, and its opening can accommodate the guide block 230, providing obstacle avoidance space for the relative displacement of the guide block 230 and the sliding member 240, and preventing the top of the guide block 230 from directly abutting against the first material handling plate 220 and hindering the rotation of the first material handling plate 220.

[0043] In addition, a support boss 232 can be provided on the guide block 230. The support boss 232 is located below the straight groove 231. The bottom end of the U-shaped part 241 abuts against the support boss 232. The support boss 232 can support the sliding part 240, the first material feeding plate 220 and other structures, so as to prevent the sliding rod 242 from bearing the weight of all the components above, and thus avoid torque overload and shorten service life.

[0044] Furthermore, in the technical solution where the inclination direction of the first material handling plate 220 faces away from the center of the ring, a dust baffle 270 can also be installed on its plate surface near the first material handling cylinder 210. The angle between the dust baffle 270 and the first material handling plate 220 is greater than 0° and less than 90°. The specific angle can be determined according to the actual production requirements and the design of the dimensions and assembly of each workpiece. For example, attached... Figure 3 In this design, an L-shaped plate is provided on the surface of the first feeding plate 220 near the first feeding cylinder 210. The L-shaped plate, parallel to the plate portion of the first feeding plate 220, is used for mounting detachable fasteners such as bolts. The L-shaped plate, parallel to the plate portion of the first feeding plate 220, also serves as a dust baffle 270. When the first feeding plate 220 is in a non-feeding position, it can block the top opening of the mounting cavity 110. When the first feeding plate 220 rotates to the feeding position, the dust baffle 270 can block the top opening of the mounting cavity 110, preventing debris from falling into the mounting cavity 110 and causing malfunctions in the internal structure of the mounting cavity 110. For example, it prevents debris from getting stuck in the straight groove 231, causing the first feeding plate 220 to become immobile.

[0045] In this embodiment, the second material handling assembly 300 includes a second material handling cylinder 310 and a second material handling plate 320. The second material handling cylinder 310 is horizontally mounted on the base 100. The bottom end of the second material handling plate 320 is fixedly connected to the piston rod of the second material handling cylinder 310, and a second material handling block 330 is provided on the side of the top end facing the center of the ring. When the piston rod of the second material handling cylinder 310 extends or retracts, the second material handling plate 320 and the second material handling block 330 will move closer to or away from the center of the ring. When they move closer to the center of the ring, they can push the blue film inside the ring.

[0046] In practice, both the first material handling block 260 and the second material handling block 330 can be polyurethane blocks, which are detachably connected to the first material handling plate 220 and the second material handling plate 320, respectively, for easy installation, disassembly, and maintenance. The polyurethane blocks have a certain degree of flexibility, which can prevent rigid collisions with the blue diaphragm and thus avoid damage to the blue diaphragm.

[0047] In addition, a horizontally through mounting groove 120 can be provided on the base 100, and the second material handling cylinder 310 is placed in the mounting groove 120. The free end of its piston rod is away from the center of the ring. The bottom surface of the mounting groove 120 can provide good support for the second material handling cylinder 310, and can also reduce the space occupied by the second material handling assembly 300 outside the base 100, thereby improving the integration of the mechanism and the space utilization rate.

[0048] Taking a linear synchronous belt-synchronous wheel mechanism for conveying blue diaphragms as an example, when the blue diaphragm reaches the suction station of the suction cup (specifically, the area where the blue diaphragm is located on the synchronous belt-synchronous wheel mechanism when the suction cup adsorbs the blue diaphragm; theoretically, the center of the suction station coincides with the center of the blue diaphragm, and the edges and corners correspond), the first material handling components 200 on both sides of the blue diaphragm simultaneously operate, adjusting the blue diaphragm so that the line connecting its own center and the center of the suction station is perpendicular to the material conveying direction. Simultaneously, the second material handling components 300 on the other two sides of the blue diaphragm simultaneously operate, adjusting the blue diaphragm so that the line connecting its own center and the center of the suction station is parallel to the material conveying direction. At this point, the center of the blue diaphragm coincides with the center of the suction station. This meets the operational requirements for round blue diaphragms. For square blue diaphragms, the design of the shape of the first material handling block 260 and the second material handling block 330, the orientation of the turning shaft, and the piston rod orientation of the second material handling cylinder 310, etc. (see attached diagram), are required. Figure 1 This allows the surfaces of the first material handling block 260 and the second material handling block 330 that contact the blue film to be parallel to the edge of the blue film, thus achieving the center and corner alignment of the square blue film with the adsorption station.

[0049] The beneficial effects of this application are as follows: It provides a blue film feeding mechanism that adjusts the center position and corner direction of the blue film after it is transferred to the adsorption station by the feeding mechanism and before it is adsorbed by the suction cup, so that the center of the blue film coincides with the center of the adsorption station and the corners correspond, so that the blue film can generate a good adsorption effect with the suction cup and be accurately transferred by the suction cup to the area in the electroplating tank where the electroplating solution and electric field are evenly distributed, thereby avoiding the problems of film collision or uneven coating deposition and improving the production yield.

[0050] 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.
