[0002] During the production process of perovskite solar cells, the perovskite cells need to be coated.

[0003] In the process of conveying perovskite glass substrates by existing coating machines, due to the large size of the perovskite glass substrates, which are usually greater than or equal to 600mm*600mm, the large-sized glass substrates have a poor match with the conveying components during the transmission process, resulting in the perovskite glass substrates often shifting during transportation, thereby affecting the subsequent positioning process.

[0004] Therefore, it is necessary to design a negative pressure adsorption conveying device, conveying equipment and coating equipment to solve the problem that large-size perovskite glass substrates are easily offset. Utility Model Content

[0006] In one embodiment, each adsorption groove is provided with an adsorption joint hole.

[0007] In one embodiment, the adsorption hole groups are arranged along the length direction of the conveyor belt.

[0008] In one embodiment, the adsorption hole group is located in the middle of the conveyor belt and is suitable for being connected to the negative pressure chamber when it is above the adsorption slot.

[0009] In a second aspect, the utility model also provides a conveying device, which comprises: two adsorption conveying devices as described in the claim, respectively located on both sides of the coating platform to carry the corresponding ends of the substrate; and a driver for driving the two conveyor belts to convey synchronously.

[0010] In one embodiment, a guide member is provided on the outer side of the conveyor belt.

[0011] In one embodiment, the guide member is arranged along the length direction of the conveyor belt.

[0013] In one embodiment, the driver comprises: a motor and a synchronization rod; wherein both ends of the synchronization rod are respectively connected to corresponding conveyor belts; and the motor is suitable for driving the two conveyor belts to rotate through the synchronization rod.

[0014] In a third aspect, the utility model further provides a coating device, comprising the negative pressure adsorption conveying device and / or the conveying device as described above.

[0015] The beneficial effect of the utility model is that the support member of the negative pressure adsorption conveying device is fixedly arranged, and the conveyor belt is carried on the support member and moves, so that the adsorption groove forms a chamber. When the negative pressure source connected to the chamber works, the chamber forms a negative pressure chamber.

[0028] In some embodiments, the support member 3 is fixedly arranged, and the conveyor belt 1 is placed on the support member 3 and moves so that the adsorption groove 31 forms a chamber. When the negative pressure source connected to the chamber is working, the chamber forms a negative pressure chamber. Since an adsorption hole group 11 is provided on the conveyor belt 1, and the substrate 2 is placed on the conveyor belt 1, the adsorption hole group 11 will be covered. Therefore, when the adsorption hole group 11 moves to the adsorption groove 31, the substrate 2 will be sucked by the negative pressure, thereby preventing the substrate 2 from moving.

[0029] In some embodiments, the substrate 2 may be, but is not limited to, a glass substrate.

[0030] In some embodiments, each adsorption slot 31 is provided with an adsorption connector hole 32 .

[0033] In some embodiments, the adsorption hole group 11 is located in the middle of the conveyor belt 1 and is suitable for being connected to the negative pressure chamber when it is above the adsorption slot 31 .

[0034] In some embodiments, when a plurality of adsorption slots 31 are provided, it is necessary to ensure that each adsorption slot 31 has an adsorption hole during the movement of the conveyor belt 1 .

[0035] like Figure 3 As shown, at least one embodiment provides a conveying device, which includes: two adsorption conveying devices 4 as described above, respectively located on both sides of the coating platform 5 to carry the corresponding ends of the substrate 2; and a driver 6 for driving the two conveyor belts 1 to convey synchronously.

[0037] like Figure 4 As shown, in some embodiments, a guide member 7 is provided on the outer side of the conveyor belt 1 .

[0038] In some embodiments, the guide member 7 is arranged along the length direction of the conveyor belt 1.

[0039] In some embodiments, the guide member 7 is used to prevent the substrate 2 from deviating.

[0040] In one application scenario, the guide member 7 is a wool guide strip, which has sliding friction, is more wear-resistant, and is convenient for limiting the position of the substrate 2.

[0041] In another application scenario, the guide member 7 adopts a guide roller group, which is a rolling friction, has smaller friction resistance, and is more convenient and quick to transport the substrate 2.

[0042] like Figure 5 As shown, in some embodiments, the driver 6 includes: a motor 61 and a synchronization rod 62; wherein the two ends of the synchronization rod 62 are respectively connected to the corresponding conveyor belts 1; and the motor 61 is suitable for driving the two conveyor belts 1 to rotate through the synchronization rod 62.

[0044] like Figure 3As shown, at least one embodiment further provides a coating device, including a conveying device and a lifting mechanism 8; wherein each negative pressure adsorption conveying device 4 in the conveying device is provided with an independent lifting mechanism 8, and the lifting mechanism 8 is controlled by a servo motor to lift and lower; specifically, before coating starts, the substrate 2 is transferred to the top of the coating platform 5 by the negative pressure adsorption conveying device 4, and the lifting mechanisms 8 at both ends drive the negative pressure adsorption conveying device 4 to descend to the coating platform 5, and the lifting mechanisms 8 at both ends continue to drive the negative pressure adsorption conveying device 4 to descend so that the substrate 2 is separated from the negative pressure adsorption conveying device 4, and the coating operation starts at this time; when the coating is completed, the lifting mechanisms 8 at both ends drive the negative pressure adsorption conveying device 4 to rise and lift the substrate 2, and drive the synchronization rod 62 and the negative pressure adsorption conveying device 4 to move through the driver 6 to transport the substrate 2.

[0045] For the specific structure and implementation process of the adsorption and conveying device and the conveying equipment, please refer to the relevant discussion in the above embodiments, which will not be repeated here.

[0046] In summary, the support member 3 of the negative pressure adsorption conveying device is fixedly arranged, and the conveyor belt 1 is carried on the support member 3 and moves, so that the adsorption groove 31 forms a chamber. When the negative pressure source connected to the chamber works, the chamber forms a negative pressure chamber. Since the adsorption hole group 11 is provided on the conveyor belt 1, negative pressure is formed at the adsorption hole group 11. When the substrate 2 covers the adsorption hole group 11, it will be sucked by the negative pressure to prevent movement.
