Detailed Implementation

[0032] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] like Figures 1-4As shown, this embodiment provides a solar cell sorting machine, which mainly includes a vacuum track 100, a drive device 300, a vacuum pumping device 400, and a vacuum control device 500. Multiple vacuum tracks 100 are arranged side-by-side along a first direction, and multiple material boxes 200 are arranged directly below each vacuum track 100. The material boxes 200 are arranged along a second direction, and the first and second directions are perpendicular to each other. The vacuum track 100 is used to adsorb and transport solar cells 10. Multiple drive devices 300 are provided, and each drive device 300 corresponds one-to-one with a vacuum track 100. The drive devices 300 are driven and connected to the vacuum track 100, and can drive the vacuum track 100 to rotate so that the vacuum track 100 can transport the solar cells 10. The vacuum pumping device 400 is connected to the vacuum track 100. The vacuum control device 500 is mounted on the vacuum track 100 and is connected to both the vacuum pumping device 400 and the vacuum track 100. The vacuum control device 500 is used to control the on / off state of the vacuum within the vacuum track 100. It should be noted that the first direction in this embodiment is... Figure 1 The X-axis direction in the diagram, the second direction is... Figure 1 The Y-axis direction in the diagram.

[0037] Based on the above design, in this embodiment, the solar cell sorting machine also includes a controller (not shown in the figure). The controller is signal-connected to the drive device 300, the vacuum device 400, and the efficiency tester at the front end of the solar cell sorting machine. The controller can transmit the grading signal emitted by the efficiency tester to the drive device 300 and the vacuum device 400, thereby enabling the drive device 300 to drive the vacuum track 100 to rotate precisely. When the vacuum track 100 carries the solar cells 10 to the pre-sorting hopper 200, the vacuum device 400 can disconnect the vacuum, allowing the solar cells 10 to automatically fall into the pre-sorting hopper 200, thus completing the sorting of the solar cells 10. Through the arrangement of the vacuum track 100, the drive device 300, and the vacuum device 400, the vacuum track 100 can adsorb and transport the solar cells 10, thereby avoiding the use of electric cylinder modules in traditional technology, saving costs, improving the transport efficiency of the solar cells 10, and thus improving the processing and manufacturing efficiency of the solar cells 10.

[0038] Optionally, in this embodiment, both the drive device 300 and the vacuum track 100 can be configured as four tracks, and the drive device 300 can be configured as a motor. The vacuum pumping device 400 can be configured as a commonly available vacuum pump set. It should be noted that... Figure 2The vacuum pumping device 400 shown is not connected to the vacuum track 100, but in actual operation, the vacuum pumping device 400 is connected to the vacuum track 100 through a certain number of hoses. The vacuum control device 500 can be set as a common component such as a vacuum valve or solenoid valve available on the market.

[0039] It should be noted that the controller is a standard component in the field of solar cell manufacturing technology. Therefore, the working principle and specific structure of the controller will not be described in detail in this embodiment.

[0040] like Figures 2-3 As shown, in this embodiment, each vacuum track 100 includes multiple independent vacuum chambers 110 and a conveyor belt 120. The multiple vacuum chambers 110 are arranged sequentially along the second direction. The conveyor belt 120 is wound around the outer wall of the multiple vacuum chambers 110, and multiple sets of through holes 130 are opened on the conveyor belt 120, which connect to the vacuum chambers 110. The driving device 300 is drivenly connected to the conveyor belt 120, and the conveyor belt 120 can adsorb and transport the solar cell 10 through the through holes 130.

[0041] Optionally, the vacuum control device 500 is configured in multiple sets, with each set of vacuum control devices 500 corresponding to one of the multiple vacuum chambers 110. This allows each vacuum control device 500 to independently control the vacuum on / off of each vacuum chamber 110, thereby preventing the conveyor belt 120 from adsorbing or releasing the solar cell 10 and facilitating the accurate sorting of the solar cell 10.

[0042] Optionally, in this embodiment, multiple sets of through holes 130 are arranged at equal intervals, and multiple sets of through holes 130 are arranged corresponding to multiple vacuum chambers 110. Each vacuum chamber 110 is provided with a material box 200 below it. The multiple sets of through holes 130 are arranged at equal intervals, which is conducive to the uniform distribution of the material boxes 200, thereby saving the internal space of the solar cell sorting machine and making the size of the solar cell sorting machine smaller.

[0043] like Figure 1 and Figure 4As shown, in this embodiment, the solar cell sorting machine further includes a cell transfer device 600, which is disposed at the front end of the vacuum track 100. The cell transfer device 600 is used to transport the solar cells 10 to the vacuum track 100. Specifically, the cell transfer device 600 in this embodiment has a first station 1000 and a second station 2000 arranged sequentially along a second direction. Multiple first stations 1000 and second stations 2000 are configured, with each vacuum track 100 having one first station 1000 and one second station 2000. The cell transfer device 600 is signal-connected to a controller, and can transport any solar cell 10 from one first station 1000 to any other first station 1000 according to the signal issued by the controller. This allows the solar cells 10 to be flexibly sorted to different vacuum tracks 100, thereby improving the sorting efficiency of the solar cells 10.

[0044] Optionally, the number of first workstations 1000 and second workstations 2000 is the same. Each vacuum track 100 is configured with one first workstation 1000 and one second workstation 2000, and the arrangement direction of the first workstations 1000 and the second workstations 2000 is the same as the conveying direction of the conveyor belt 120. That is, the transport direction of the solar cell 10 by the cell handling device 600 is parallel to the conveying direction of the solar cell 10.

[0045] like Figure 1 As shown, in this embodiment, the solar cell transfer device 600 includes a cylinder 610, a suction cup 620, and a sliding plate 630. The cylinder 610 is driven to the suction cup 620, enabling the suction cup 620 to move up and down. The cylinder 610 is slidably connected to the sliding plate 630. The sliding plate 630 is mounted above four vacuum tracks 100, allowing the cylinder 610 to slide on the sliding plate 630, thus enabling flexible handling of the solar cells 10.

[0046] like Figure 1 and Figure 4As shown, in this embodiment, a third station 3000 is also provided below the vacuum track 100. The third station 3000 is located upstream of the first material box 200, and the solar cell 10 can be transferred from the second station 2000 to the third station 3000. A lifting device 700 is provided below the third station 3000. The lifting device 700 is used to lift the solar cell 10 of the third station 3000 onto the vacuum track 100 so that the solar cell 10 is attracted by the vacuum track 100. In this way, when the solar cell 10 is transferred from the first station 1000 and the second station 2000 to the third station 3000, the lifting device 700 can lift the solar cell 10 of the third station 3000 so that the solar cell 10 can be attracted by the conveyor belt 120 on the vacuum track 100, and then the conveyor belt 120 can carry the solar cell 10 to flow into the pre-sorting material box 200. The lifting device 700 is a conventional component in the prior art, and its structural features will not be described in detail here.

[0047] In this embodiment, belt conveyors are installed at the first station 1000, the second station 2000, and the third station 3000 to transport the solar cell 10 and improve work efficiency.

[0048] For example, this embodiment includes four first workstations 1000, four second workstations 2000, and four third workstations 3000. For ease of describing the work process, the four first workstations 1000 are numbered A1, A2, A3, and A4; the four second workstations 2000 are numbered B1, B2, B3, and B4; and the four third workstations 3000 are numbered C1, C2, C3, and C4.

[0049] like Figure 1 As shown, in this embodiment, the solar cell sorting machine also includes a connecting arm 800, which connects multiple parallel vacuum tracks 100 together. That is, in this embodiment, the connecting arm 800 connects four vacuum tracks 100 together, thereby ensuring the consistency and parallelism of the four vacuum tracks 100, improving the accuracy of the vacuum tracks 100 in conveying the solar cells 10, and preventing the solar cells 10 from falling outside the material box 200.

[0050] The working process of the solar cell sorting machine in this embodiment is as follows:

[0051] The solar cell 10 is conveyed to the first station 1000. The cell transfer device 600 determines whether the solar cell 10 should be directly transmitted (DC) or requires a split current transmission based on the gear signal of the efficiency tester. For example, the cell transfer device 600 moves the solar cell 10 to the first station 1000A1 according to the gear signal. The first station 1000A1 then transmits it to the second station 2000B1, and then to the third station 3000C1. The lifting device 700 of the third station 3000C1 lifts the solar cell 10 and sends it to the conveyor belt 120 on the vacuum track 100. The conveyor belt 120 adsorbs and conveys the solar cell 10. The driving device 300 drives the conveyor belt 120 to move according to the gear signal. When it moves to the pre-sorting box 200, the vacuum control device 500 breaks the vacuum, so that the solar cell 10 can fall into the pre-sorting box 200.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention.
