Description

Technical Field

[0001] The utility model belongs to the technical field of annealing furnaces, and in particular relates to a basket-type tunnel furnace. Background Art

[0002] Perovskite solar cells generally use a one-step or two-step process. The one-step process requires three steps: coating-VCD-annealing, and the two-step process requires a coating-annealing step. Both processes require annealing equipment.

[0003] When processing perovskite solar cells, the existing annealing equipment places the cells at the entrance of the annealing furnace by loading. After the cells enter the annealing furnace and complete the annealing process, they are unloaded from the discharge port of the annealing furnace.

[0004] However, the existing annealing furnace can only hold one perovskite solar cell at a time, which has low working efficiency. When mass production is required, multiple annealing furnace equipment is required, which occupies a large area. In addition, batches of perovskite solar cells are easily damaged during the transfer process.

[0005] Therefore, it is necessary to design a basket-type tunnel furnace to solve the problems of low efficiency and fragility of perovskite solar cells during annealing and transfer. Utility Model Content

[0006] The utility model aims to provide a flower basket type tunnel furnace to solve the technical problems described in the background technology.

[0007] In order to solve the above technical problems, the utility model provides a flower basket type tunnel furnace, which includes: a tunnel furnace body, in which a conveyor line is arranged; a flower basket rotary assembly line, whose feeding end and receiving end are respectively located at the entrance and the exit of the tunnel furnace body, and form a conveying loop with the conveyor line in the tunnel furnace body; and a flower basket, which is arranged on the conveying loop and is used to carry battery cells; wherein a rotary machine is arranged at the receiving end of the flower basket rotary assembly line; when the flower basket is located at the feeding end, its opening faces away from the tunnel furnace body to receive the battery cells conveyed by the feeding elevator; and when the flower basket is located at the receiving end, it is suitable for turning the opening direction by the rotary machine to unload the battery cells to the receiving elevator.

[0008] In one embodiment, the flower basket includes: a mounting frame on which a multi-layer supporting frame is arranged; wherein one end of the supporting frame is connected to the mounting frame, and the other end is left empty.

[0009] In one embodiment, the support frame includes: a plurality of support bars; each of the support bars is arranged horizontally.

[0010] In one embodiment, a plurality of idler wheels are disposed on the bearing rod; the idler wheels are arranged along the length direction of the bearing rod.

[0011] In one embodiment, the mounting frame is U-shaped.

[0012] In one embodiment, at least one supporting rod is vertically arranged on each side of the mounting frame.

[0013] In one embodiment, two first heating modules are disposed in the tunnel furnace body; the two first heating modules are respectively located on both sides of the conveying line to heat the battery cells in the flower baskets thereon.

[0014] In one embodiment, a liftable second heating module is disposed in the tunnel furnace body.

[0015] In one embodiment, both the feeding elevator and the receiving elevator are provided with conveyor belts.

[0016] In one embodiment, the feeding elevator is in the same straight line as the tunnel furnace body.

[0017] The beneficial effect of the utility model is that the flower basket of the flower basket type tunnel furnace receives the battery cells at the feeding end of the flower basket rotary assembly line. In order to facilitate the reception of the battery cells, its opening faces away from the tunnel furnace body. After the flower basket receives the battery cells, the flower basket rotary assembly line transports the entire flower basket with the battery cells to the conveying line in the tunnel furnace body. The flower basket on the conveying line is sent out after annealing of the tunnel furnace body. The receiving end of the flower basket rotary assembly line receives the sent flower basket. Since the opening of the sent flower basket is toward the tunnel furnace body, a rotary machine is provided at the receiving end to turn the flower basket so that its opening faces away from the tunnel furnace body, thereby facilitating the unloading of the battery cells to the receiving elevator. By providing the flower basket, the scheme enables the tunnel furnace body to receive multiple battery cells at a time, thereby increasing the annealing efficiency. At the same time, since the flower basket is transported by the conveying loop, the damage to the battery cells during the transportation process can be reduced.

In order to facilitate receiving the battery cell 7, its opening 41 is facing away from the tunnel furnace body 1. After the flower basket 4 receives the battery cell 7, the flower basket rotary assembly line transports the entire flower basket 4 with the battery cell 7 to the conveying line 2 in the tunnel furnace body 1. The flower basket 4 on the conveying line 2 is sent out after annealing in the tunnel furnace body 1. The receiving end 32 of the flower basket rotary assembly line receives the sent flower basket 4. Since the opening 41 of the sent flower basket 4 is facing the tunnel furnace body 1, a rotating machine 33 is provided at the receiving end 32 to turn the flower basket 4 so that its opening 41 faces away from the tunnel furnace body 1, thereby facilitating unloading of the battery cell 7 to the receiving elevator 6. This solution enables the tunnel furnace body 1 to receive multiple battery cells 7 at a time by providing the flower basket 4, thereby increasing the annealing efficiency. At the same time, since the flower basket 4 is transported by the conveying loop, the damage of the battery cell 7 during the transportation process can be reduced.

[0038] like Figure 2 As shown, in some embodiments, the flower basket 4 includes: a mounting frame 44, on which a multi-layer support frame 42 is arranged; wherein one end of the support frame 42 is connected to the mounting frame 44, and the other end is left empty.
