[0034] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] Furthermore, the conveying device 3 includes a linear moving base 31 slidably connected to the conveying guide rail 4.

A gas storage tank 34 is provided on the linear moving base 31 and inside the frame 32. A vacuum pump 35 is also provided on the linear moving base 31 and inside the frame 32. The vacuum pump 35 is connected to the adsorption platform 33, so that the adsorption platform 33 can effectively adsorb the flexible solar chip for subsequent conveying.

Multiple vacuum status monitors 37 are also provided on the top of one side of the frame 32, each corresponding to a multiple adsorption platform 33, which can monitor the adsorption state of the flexible solar chip during transportation, and can send an abnormal signal in time when an abnormality occurs. After receiving the abnormal signal at the receiving end, the monitor can promptly remind the staff.

[0038] Furthermore, the temporary rack 5 includes a base frame 51 and a temporary platform 52. The temporary platform 52 is located directly above the base frame 51. The temporary platform 52 is used to support the flexible solar cells and can be used for subsequent testing.

[0039] Furthermore, the transfer device 7 includes a transfer base 71 slidably connected to the transfer guide rail 6. A lifting cylinder 72 is provided on one side of the transfer base 71. A transfer frame 73 is connected to the telescopic end of the lifting cylinder 72. A suction cup 74 is provided at the bottom of the transfer frame 73. Both the lifting cylinder 72 and the suction cup 74 are connected to an external air source, which can control the lifting of the transfer frame 73 and the suction cup 74 to adsorb the flexible solar chip. A drive motor 75 is also provided on the other side of the transfer base 71. The drive motor 75 controls the horizontal movement of the transfer base 71 on the transfer guide rail 6 through a transmission structure.

[0040] Furthermore, the transfer device 9 includes a transfer guide rail 91, a linear drive mechanism 92 is provided on the transfer guide rail 91, a transfer frame 93 is provided on the linear drive mechanism 92, and a transfer stage 94 is provided on the transfer frame 93, which can transfer the flexible solar chip to the transfer device 7 for subsequent transfer.

[0041] Furthermore, the visual inspection device 8 includes a bracket 81, a top plate 82 fixedly connected to one side of the bracket 81, a positioning frame 83 fixedly connected to one side of the bracket 81, a CCD industrial camera 84 fixedly connected to one side of the positioning frame 83, and an extension lens 85 connected to the shooting end of the CCD industrial camera 84. The CCD industrial camera 84 performs visual inspection on the products on the temporary rack 5, and can promptly remind the staff to replace the products when abnormalities occur, thereby reducing the impact of defective products in subsequent processing.

[0042] Furthermore, the alignment device 10 includes an outer frame 101. Two sets of sleeves 102 are fixedly connected to one side of the inner side of the outer frame 101. Telescopic rods 103 are slidably mounted on both sets of sleeves 102. A top block 104 is connected to one end of each set of telescopic rods 103. A groove 105 adapted to the top block 104 is formed on one side of the outer frame 101. A contact sensor 106 is provided inside the top block 104. A contact groove 107 is formed on the outer frame 101 at the corresponding position of the contact sensor 106. The contact sensor 106 penetrates into the contact groove 107 and makes contact with it, indicating that the top block 104 has moved into position, and at the same time, that the conveying device 3 has moved into position. Buffer springs 108 are provided on one side of the inside of both sets of sleeves 102, and the other ends of the two sets of telescopic rods 103 are respectively connected to the two sets of buffer springs 108, so that after the conveying device 3 returns to the initial position, the top block 104 can be reset under the action of the buffer springs 108, enabling subsequent monitoring and ensuring that the conveying device 3 has the same stroke each time.

[0043] Furthermore, an alignment monitoring mechanism 11 is provided on the side of the conveyor frame 2 and close to the transfer device 7. The alignment monitoring mechanism 11 uses visual monitoring to determine whether the suction cup 74 and the transfer stage 94 are fully aligned when transferring the flexible solar chip, so as to ensure the accuracy of the transfer work.

[0044] The implementation principle of this embodiment is as follows: The flexible solar chip is first received by the transfer device 9. The transfer device 9 moves the transfer frame 93 on the transfer guide rail 91 through the linear drive mechanism 92, so that the transfer platform 94 is accurately positioned to receive the chip from the upstream equipment. Subsequently, the transfer device 7 is started. The transfer base 71 moves along the transfer guide rail 6 to above the transfer device 9 under the drive of the drive motor 75. The lifting cylinder 72 lowers the transfer frame 73. The suction cup 74 picks up the chip and rises, moving horizontally to the position of the temporary rack 5 and placing the chip on the temporary platform 52. The visual inspection device 8 performs automatic visual inspection on the chip on the temporary rack 5 through the CCD industrial camera 84 and the extension lens 85 to identify surface defects or positional deviations. Defective products are marked or removed. After passing the inspection, when the conveying device 3 approaches the temporary rack 5, the positioning device 10 is started. The top block 104 contacts the receiving plate on the outer frame 101 through the telescopic rod 103 and the buffer spring 108. The contact groove 107 and contact sensor 106 send a signal, causing the conveying device 3 to stop precisely near the temporary rack 5. The transfer device 7 then activates again, with the suction cup 74 picking up the chip. The chip is then transferred to the adsorption platform 33 of the conveying device 3 via the lifting cylinder 72 and horizontal movement. The conveying device 3 moves along the conveying guide rail 4 via the linear moving base 31 to avoid impact. The vacuum pump 35 and the air storage tank 34 provide vacuum adsorption force, allowing the adsorption platform 33 to stably adsorb the chip for transport. During the transport process, the solenoid valve 36 independently controls the vacuum state of each adsorption platform 33, and the vacuum state monitor 37 monitors the adsorption situation in real time to ensure chip safety. When the chip is transported to the vicinity of the flipping device 1, the flipping device 1 flips the chip to the correct orientation for subsequent processing steps. The entire process achieves efficient and non-destructive automated processing through the coordination of transfer, transfer, detection, transport, and flipping, ensuring production efficiency and product yield.
