Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell technology, and in particular to a single-film loading and unloading device. Background Technology

[0002] Physical vapor deposition (PVD) is a technique that uses physical methods such as evaporation and sputtering to vaporize the coating material and deposit it onto a substrate surface to form a film. Due to its advantages such as simple process, uniform and dense film formation, and strong adhesion to the substrate, PVD is widely used in the field of solar cells. With the increasing prevalence of solar cells, reducing costs and increasing production capacity have become key priorities for solar cell companies.

[0003] The PVD process uses AR atoms as a medium and introduces magnetron sputtering technology for physical vapor deposition to coat silicon wafers. During magnetron sputtering, the entire carrier substrate is coated. The carrier substrate does not stop within the process chamber, resulting in a fluid coating process. The coating is applied indiscriminately to both the carrier substrate and the solar cell substrate. During the PVD process, a single mold needs to be placed at a predetermined position on the carrier substrate to test and monitor the coating process data, preventing issues such as unqualified coatings and low efficiency. In practice, the single mold to be coated is placed on the carrier substrate and transported along with other solar cells on the carrier substrate to the process chamber for coating via a conveyor belt.

[0004] In existing technologies, the main method involves manual handling of single-mode components in the carrier board buffer area, which is inefficient and requires a high level of manual labor. Utility Model Content

[0043] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] like Figures 1 to 3As shown, this embodiment of the invention provides a single-film pick-and-place device, including a transfer platform 100, a pick-and-place mechanism 200, and a feeding mechanism 300. The transfer platform 100 is disposed above a carrier plate 400. The transfer platform 100 includes a first track 110 and a first moving part 120 arranged along a first horizontal direction. The first moving part 120 is slidably disposed on the first track 110. A second sliding track 121 arranged along a second horizontal direction is disposed on the first moving part 120, and the second horizontal direction is perpendicular to the first horizontal direction. The pick-and-place mechanism 200 is slidably disposed on the second sliding track 121. The pick-and-place mechanism 200 is provided with a gripping component 210, which is used to grip the single film. The feeding mechanism 300 is disposed on one side of the transfer platform 100 and is used to carry the single film.

[0045] That is, the single-film picking and placing device provided by this utility model, by setting a first track 110 and a second sliding track 121 perpendicular to each other on the transfer platform 100, can drive the picking and placing mechanism 200 to move to various positions above the carrier plate 400, thereby placing the single film picked up from the feeding mechanism 300 to various positions on the carrier plate 400. This solves the technical problem in the prior art that the single film needs to be manually picked and placed in the buffer area of ​​the carrier plate 400, which is inefficient and has a high labor intensity. It improves the efficiency of single film picking and placing and ensures the accuracy of single film picking and placing.

[0046] Specifically, two first tracks 110 are provided, arranged parallel to each other in the horizontal direction. A carrier plate 400 is positioned between the two first tracks 110, and a first moving part 120 is slidably positioned above the first tracks 110. A second sliding track 121 is arranged in a horizontal direction perpendicular to the first tracks 110, and a pick-and-place mechanism 200 is slidably positioned on the second sliding track 121. Thus, the movement of the pick-and-place mechanism 200 at various positions above the carrier plate 400 can be achieved by the sliding of the first moving part 120 on the first track 110 in conjunction with the sliding of the pick-and-place mechanism 200 on the second sliding track 121. The pick-and-place mechanism 200 is equipped with a gripping component 210 capable of gripping single films. The gripping component 210 can be configured as a pneumatic suction cup 213 or a mechanical gripper to grip the single films, thereby gripping the single films positioned on the feeding mechanism 300, conveying them to various positions above the carrier plate 400, and then placing them down, completing the automatic pick-and-place of single films.

[0047] Preferably, the first moving part 120 includes a first mounting bracket 122 and a first driving member; two first tracks 110 are arranged parallel to each other at intervals, the two first mounting brackets 122 are respectively movably mounted on the first tracks 110, the two ends of the second sliding track 121 are respectively connected to the first mounting brackets 122, and the first driving member is connected to the first mounting brackets 122 in a transmission connection to drive the first mounting brackets 122 to move along the first tracks 110.

[0048] Specifically, the first mounting frame 122 can be configured as a rectangular frame or an "I"-shaped frame arranged vertically. The first track 110 can be configured as an "I"-shaped track, a triangular track, or a round steel track. A drive roller can be located at the bottom of the first mounting frame 122, and the first mounting frame 122 moves along the first track 110 by the roller rolling on the track. The first driving component can be configured as a drive motor, which drives the drive roller to rotate via a coupling. The second sliding track 121 can be configured as a metal shaft, with both ends fixed to the top of the first mounting frame 122, allowing the pick-and-place mechanism 200 to slide on the second sliding track 121.

[0049] Furthermore, the mobile platform also includes a transmission screw 130, a second drive component 150, and a second slider 140; two second sliding rails 121 are arranged parallel to each other at intervals, the transmission screw 130 is disposed between the two second sliding rails 121, the two ends of the transmission screw 130 are respectively rotatably disposed on two first mounting brackets 122, the second slider 140 is threadedly connected to the transmission screw 130, the two sides of the pick-and-place mechanism 200 are respectively slidably disposed on the second sliding rails 121, and the second slider 140 is fixed to the pick-and-place mechanism 200.

[0050] Specifically, two second sliding rails 121 are arranged parallel to each other on the first mounting bracket 122. Mounting holes are provided on the top of the first mounting bracket 122 along a second direction, allowing the two ends of the transmission screw 130 to be rotatably mounted on the two first mounting brackets 122 respectively. The second slider 140 is threaded to the transmission screw 130 and fixed to the pick-and-place mechanism 200 with bolts. Through holes are provided on both sides of the pick-and-place mechanism 200 for the second sliding rails 121 to pass through. At this time, the transmission screw 130, the second sliding rails 121, the second slider 140, and the pick-and-place mechanism 200 cooperate to form a screw-nut structure. The second driving component 150 can be a stepper motor, fixed to either of the first mounting brackets 122 with bolts, and its output shaft can be connected to the transmission screw 130 via gears or a coupling. Thus, the second driving component 150 can drive the transmission screw 130 to rotate, thereby allowing the pick-and-place mechanism 200 to slide along the second sliding rails 121.

[0051] Furthermore, the pick-and-place mechanism 200 includes a first housing 220, a third sliding rail 230, and a third driving member 240; the first housing 220 is provided with a first receiving cavity, the third sliding rail 230 is arranged horizontally at the top of the first receiving cavity, the gripping component 210 is slidably arranged on the third sliding rail 230, and the driving end of the third driving member 240 is connected to the gripping component 210 to drive the gripping component 210 to move along the third sliding rail 230.

[0052] Specifically, the first housing 220 is generally square, and the first accommodating cavity is square and located inside the first housing 220. The third sliding track 230 is a metal boat, horizontally positioned at the top of the first accommodating cavity. The gripping component 210 is slidably mounted on the third sliding track 230. To ensure the stability of the gripping component 210's movement, two third sliding tracks 230 can be provided, parallel to each other and spaced apart. The third driving component 240 is an electric push rod, bolted to one end of the third sliding track 230, and its output end is connected to the gripping component 210 mounted on the third sliding track 230, thereby driving the gripping component 210 to slide on the third sliding track 230.

[0053] Preferably, the gripping component 210 includes a lifting drive component 211, a mounting plate 212, and a suction cup 213. The lifting drive component 211 is fixed to the mounting plate 212, the mounting plate 212 is slidably disposed on the third sliding track 230, and the suction cup 213 is disposed at the driving end of the lifting drive component 211.

[0054] Specifically, the mounting plate 212 is a rectangular plate with through holes on both sides for the third sliding track 230 to pass through. The mounting plate 212 is connected to the output end of the third drive component 240 by bolts, so that it moves with the drive component. The lifting drive component 211 is an electric push rod, which is fixed to the mounting plate 212 by bolts. The lifting drive component 211 is arranged vertically downward, and the suction cup 213 is fixed to the end of its push rod and rises and falls with the electric push rod. Thus, the electric push rod can drive the suction cup 213 to rise and fall, allowing the suction cup 213 to descend to adsorb the single film, and then rise again to slide on the third sliding track 230 with the mounting plate 212, thereby changing the position of the single film.

[0055] Furthermore, a feed inlet 221 is provided on one side of the bottom of the first housing 220 so that the feeding mechanism 300 can partially extend into the feed inlet 221. A discharge hole is provided at the bottom of the first housing 220, and the discharge hole faces a preset position on the carrier plate 400.

[0056] Specifically, the feeding mechanism 300 is connected to the picking and placing mechanism 200 via connecting parts and other structures, and moves with the picking and placing mechanism 200. The inlet 221 and the outlet 221 are respectively located on both sides of the bottom of the first housing 220. The outlet 221 is located on the bottom surface of the first housing 220, and is rectangular in shape and facing downwards. The inlet 221 is located on the bottom surface and side wall of the first housing 220, facilitating the insertion of the feeding mechanism 300. Thus, the picking component can move above the inlet 221 to pick up the single film, and then move above the outlet 221 to place the single film onto the preset position on the carrier plate 400 below.

[0057] Furthermore, the feeding mechanism 300 includes a second housing 310, a telescopic push rod 320, and a conveying assembly; the second housing 310 is provided with a second receiving cavity, which can accommodate multiple single films stacked together. A discharge hole is provided on one side of the second receiving cavity, and a through hole is provided on the other side of the second receiving cavity. The telescopic push rod 320 is fixed to the outside of the second housing 310 near the through hole. The telescopic push rod 320 can extend into the through hole to push the single film out of the discharge hole. One end of the conveying assembly is provided on the outside of the second housing 310 near the discharge hole, and the other end of the conveying assembly extends into the inlet 221.

[0058] Specifically, the second housing 310 is cylindrical in shape, and the second receiving cavity is located inside the second housing 310. Its cross-section is square to accommodate the shape of a conventional single-layer membrane. The discharge port is a long operating port located at the top of the side wall of the housing, with a width consistent with the width of the single-layer membrane and a height consistent with its thickness. A through-hole is located on the other side, and the telescopic push rod 320 is an electric push rod, fixed to the outside of the through-hole by bolts. Thus, the top layer of single-layer membrane can be pushed out of the discharge port via the telescopic push rod 320 and sent to the conveying assembly. The conveying assembly then transports it to the inlet port for the picking assembly to grasp the single-layer membrane.

[0059] Furthermore, the feeding mechanism 300 also includes a reset component, which is disposed at one end of the second receiving cavity away from the discharge port. The reset component abuts against the single membrane and is able to push the single membrane toward the discharge port.

[0060] Specifically, the reset component is fixed at the bottom of the second receiving cavity. The reset component can be configured as a spring and a top plate. The top plate pushes the single membrane to the top wall of the second box 310, thereby ensuring that after the telescopic push rod 320 pushes the single membrane located on the top layer out of the discharge hole, the top plate can push the single membrane below back to the top layer, realizing automatic feeding of the single membrane.

[0061] Preferably, in other embodiments of this application, the reset assembly includes an airbag 341 and an air pump 342 in place of a spring. The airbag 341 is disposed in the second receiving cavity and abuts against the single membrane. The air pump 342 can inflate the airbag 341 to make the airbag 341 expand. The bottom of the second housing 310 is provided with a pressure relief hole, which communicates with the airbag 341.

[0062] Specifically, the airbag 341 is disposed within the second receiving cavity and abuts against the bottommost single membrane. The air pump 342 inflates the airbag 341, causing it to expand. The airbag 341 then pushes the single membrane against the top wall of the second housing 310 via the top plate. Once all the single membranes have been pushed out of the discharge port by the telescopic push rod 320 and delivered to the conveying assembly, the airbag 341 can be connected to the outside air by opening the pressure relief hole, expelling the gas from the airbag 341 and causing the top plate to fall back, thereby replenishing the single membranes.

[0063] Furthermore, the conveying assembly includes a conveyor belt 331, a take-up sleeve 332, and a second drive member 150; the conveyor belt 331 is wrapped around two spaced take-up sleeves 332, and the conveyor belt 331 extends along the discharge hole to the inlet 221; the second drive member 150 is connected to either take-up sleeve 332 to drive the conveyor belt 331 to rotate.

[0064] Specifically, the conveyor belt 331 is wrapped around two spaced-apart take-up sleeves 332. The second drive unit 150 is a drive motor and is connected to one of the take-up sleeves 332 via a coupling. By driving the take-up sleeve 332 to rotate through the second drive unit 150, the conveyor belt 331 can be rotated, thereby conveying the single film on the conveyor belt 331 to the feed inlet 221.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
