Description

Technical Field

[0001] This utility model relates to the technical field of solar cell processing, and in particular to a turntable mechanism for coating solar cells. Background Technology

[0002] In the production of perovskite crystalline silicon tandem solar cells, various solutions are coated onto silicon wafers to form the perovskite cell film. Therefore, the coating machine is the core equipment in cell manufacturing, because the uniformity and thickness of the film directly determine the photoelectric conversion efficiency and long-term stability of the cell.

[0003] A search revealed Chinese Patent Publication No. CN221183502U, which discloses a rotary table coating device, comprising a coating assembly and a rotating assembly. The coating assembly includes a coating head and a coating station; the coating head is used to coat the workpiece located at the coating station. The rotating assembly includes multiple rotating arms, which are used to carry workpieces and move uncoated workpieces to the coating station and / or remove coated workpieces from the coating station. By moving uncoated workpieces to the coating station and removing coated workpieces from the coating station using the rotating arms, uncoated workpieces can be placed on other rotating arms and coated workpieces can be removed simultaneously with the coating assembly. This allows for the synchronous loading, unloading, and coating of workpieces, accelerating the coating process, shortening the production cycle of perovskite solar cells, avoiding the coating assembly being idle due to workpiece loading and unloading, improving the utilization efficiency of the coating assembly, and thus reducing production costs.

[0004] In existing rotary table coating equipment, the loading and unloading of workpieces still need to be completed with the help of an external robotic arm, which results in a slow working cycle. In addition, the positioning and adaptation between the external robotic arm and the workpiece also need to be considered, making the operation cumbersome.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a turntable mechanism for coating solar cells, making it more industrially valuable. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a turntable mechanism for coating solar cells.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A turntable mechanism for coating solar cells includes a turntable, and a turntable motor for driving the turntable is mounted at the bottom of the turntable.

[0009] Four turntable mounting blocks for mounting the paper roll conveying mechanism are evenly distributed around the turntable.

[0010] The paper conveying mechanism includes a paper conveying base frame, a vacuum adsorption platform mounted on the top frame of the paper conveying base frame, a paper conveying roll mounted on the paper conveying base frame, and the paper conveying roll moving freely above the vacuum adsorption platform and within the base frame cavity located below the top frame of the paper conveying base frame.

[0011] As a further improvement of this utility model, a paper roll conveying drive motor module for driving the paper roll is provided in the base cavity of the paper roll conveying base frame, and the paper roll conveying drive motor module is installed on the base frame of the paper roll conveying base frame.

[0012] As a further improvement of this utility model, a correction motor is installed on the turntable mounting block below the base frame of the paper roll conveyor.

[0013] As a further improvement of this utility model, several motor drivers, each connected to the correction motor, are installed on the turntable.

[0014] As a further improvement of this utility model, a number of transmission guide rollers for guiding the transmission of paper rolls during operation are installed on the outer edge of the top frame of the paper roll transmission base.

[0015] As a further improvement of this utility model, several vacuum adsorption control devices are installed on the turntable, each of which is connected to the vacuum adsorption platform control.

[0016] As a further improvement of this utility model, the included angle between two adjacent turntable mounting blocks is 90 degrees.

[0017] By means of the above solution, this utility model has at least the following advantages:

[0018] This invention enables the simultaneous placement of uncoated solar cells to other rotating stations and the transport of coated solar cells through a paper roll conveying mechanism. This allows for the synchronous loading, unloading, and coating of solar cells, thereby accelerating the coating cycle and shortening the production cycle of perovskite solar cells.

[0019] This invention avoids the coating machine being in a waiting state due to the feeding and unloading of battery cells, enabling continuous coating, improving equipment utilization and product stability, and thus reducing production costs.

[0031] Example

[0032] like Figures 1-3 As shown, this utility model discloses a turntable mechanism for coating solar cells, which mainly includes a turntable 1 and four paper conveying mechanisms 2. The turntable 1 and the paper conveying mechanisms 2 complete the transmission, positioning, and coating of crystalline silicon solar cells, enabling all three to be performed simultaneously.

[0033] like Figure 4 As shown, a turntable motor 3 for driving the turntable 1 is installed at the bottom of the turntable 1. The electrical circuit is connected through the turntable's central hole and slip ring 7 to achieve 360° rotation of the turntable. Four turntable mounting blocks 8 are evenly distributed around the turntable 1 for mounting the paper conveying mechanism 2. The included angle between any two adjacent turntable mounting blocks 8 is 90 degrees. The four independent paper conveying mechanisms 2 are respectively mounted on the turntable mounting blocks 8. Figure 3 As shown, stations A, B, C, and D are arranged in a counter-clockwise direction. Each station performs different actions to achieve synchronous coating and loading / unloading (the coating work is carried out by external coating equipment).

[0034] like Figure 5 As shown, the roll paper conveying mechanism 2 includes a roll paper conveying base 10, which, from top to bottom, includes a top frame, a base frame cavity, and a bottom frame. A vacuum adsorption platform 6 is installed on the top frame of the roll paper conveying base 10. When the battery cell is conveyed to the correct position, the vacuum adsorption device 5 is activated, and the battery cell is adsorbed by the vacuum adsorption platform 6. A conveying roll paper 11 is installed on the roll paper conveying base 10. The conveying roll paper 11 is driven by the roll paper conveying drive motor module below and is used for loading and unloading battery cells. That is, it cooperates with external feeding or receiving equipment to receive incoming battery cells or to feed battery cells located on the roll paper conveying mechanism 2 out through the operation of the conveying roll paper 11.

[0035] In addition, several transmission guide rollers 12 are installed on the outer edge of the top frame of the paper conveying base 10 for guiding the paper conveying roll 11 during operation. The multiple transmission guide rollers 12 facilitate the guiding of the paper conveying roll 11 during operation.

[0036] During the aforementioned loading and unloading process, the solar cells can be aligned with the edge of the marble platform by a alignment mechanism mainly composed of the alignment motor 4 in conjunction with a vision system. Simultaneously, the motor driver 9 mounted on the turntable 1 controls the alignment motor 4. The alignment mechanism operates on the same principle as commonly used in the transport of strip-shaped workpieces in this field, and will not be elaborated further here. The paper roll conveyor drive motor module and the driver for the alignment motor 4 are integrated on the turntable surface and controlled via slip rings.

[0037] Brief description of the working process of this utility model:

[0038] The crystalline silicon solar cells are transferred from the previous process to the paper conveyor mechanism 2 at station A. The vacuum adsorption platform 6 on the paper conveyor mechanism 2 operates, adsorbing the solar cells. The turntable 1, driven by the bottom turntable motor 3, rotates 90° counterclockwise, moving the paper conveyor mechanism 2 to station B. The mechanism, driven by the correction motor 4, is aligned so that the edge of the solar cell is parallel to the edge of the marble. Simultaneously, the paper conveyor mechanism 2 at station A receives the next crystalline silicon solar cell. The turntable 1, driven by the bottom turntable motor 3, rotates 90° counterclockwise again to station C to begin coating. After coating, the turntable 1 rotates 90° counterclockwise again to station D. The vacuum adsorption platform 6 closes, and the paper conveyor mechanism 2 transfers the first crystalline silicon solar cell to the next process. This continuous rotation completes the coating of subsequent crystalline silicon solar cells. This cycle repeats continuously.
