[0039] The present application provides a flexible substrate clamping jig, aiming to improve the manufacturing efficiency of flexible perovskite photovoltaic cells.

[0040] The specific structure of the flexible substrate clamping jig of the present application will be described below:

[0041] For reference Figures 1 to 3 In a possible embodiment of the present application, the flexible substrate 2000 applied to clamp a flexible perovskite cell includes a base 10, a first clamping assembly 30, a stretching assembly 50, and a second clamping assembly 70. The base 10 is provided with a mounting position 10a for placing a glass plate, and the mounting position 10a has opposite first and second sides. The first clamping assembly 30 is located on the first side of the mounting position 10a, is mounted on the base 10, and is used to clamp the first side edge of the flexible substrate 2000. The stretching assembly 50 is located on the second side of the mounting position 10a, and is drivingly connected to the base 10. The second clamping assembly 70 is mounted on the stretching assembly 50, and is used to clamp the second side edge of the flexible substrate 2000. The stretching assembly 50 drives the second clamping assembly 70 to move away from the first clamping assembly 30.

[0042] It can be understood that, in the flexible substrate clamping jig 100 provided in the present application, the mounting position 10a of the base 10 is used to place the glass plate, the first clamping assembly 30 and the second clamping assembly 70 are respectively used to clamp the first side edge and the second side edge of the flexible substrate 2000, the second clamping assembly 70 is driven to move away from the first clamping assembly 30 by the stretching assembly 50, the flexible substrate 2000 is stretched in a stretching manner, the flexible substrate 2000 is attached to the glass plate, the flexible substrate 2000 is in a taut state, the probability of wrinkles generated in the processing process can be reduced, no gluing is required in the whole process, and the flexible substrate 2000 and the glass plate can be easily separated, so that the manufacturing efficiency of the flexible perovskite photovoltaic cell can be effectively improved. In addition, since no gluing is required, the glass plate can be reused without gluing treatment.

[0043] In actual application, the stretching assembly 50 can include a stretching body 51 and a bolt, the stretching body 51 is provided with a threaded hole 51a, the bolt is threadedly connected with the threaded hole 51a, one end of the bolt abuts against the base 10, and rotating the bolt can drive the stretching body 51 to move away from the base 10, so as to drive the second clamping assembly 70 to tension the flexible substrate 2000; the stretching assembly 50 can also directly drive the second clamping assembly 70 to tension the flexible substrate 2000 by a pneumatic cylinder; the stretching assembly 50 can also drive the second clamping assembly 70 to tension the flexible substrate 2000 by other effective manners.

[0044] In actual application, the first clamping assembly 30 can be connected with the base 10 by a bolt to clamp the first side edge of the flexible substrate 2000; the first clamping assembly 30 can also be provided with a pneumatic clamping finger to clamp the first side edge of the flexible substrate 2000; the first clamping assembly 30 can also clamp the first side edge of the flexible substrate 2000 by other effective manners. Similarly, the second clamping assembly 70 can be connected with the base 10 by a bolt to clamp the second side edge of the flexible substrate 2000; the second clamping assembly 70 can also be provided with a pneumatic clamping finger to clamp the second side edge of the flexible substrate 2000; the second clamping assembly 70 can also clamp the second side edge of the flexible substrate 2000 by other effective manners.

[0045] In combination with Figure 2 and Figure 3 In a possible implementation of the present application, the stretching assembly 50 includes a stretching body 51 and a driving member 53, the stretching body 51 is slidingly connected to the base 10, and the second clamping assembly 70 is mounted to the stretching assembly 50. The driving member 53 is drivingly connected to the stretching body 51 and abuts against the base 10, so as to drive the second clamping assembly 70 to move away from the first clamping assembly 30.

[0046] In this way, the driving member 53 drives the stretching body 51 to move, so that the second clamping assembly 70 moves, the flexible substrate 2000 is tensioned, and the stretching body 51 is stably moved along the determined sliding track by being slidably connected to the base 10.

[0047] With reference to Figure 2 and Figure 3 In a possible implementation of the present application, the stretching body 51 is provided with a threaded hole 51a. The driving member 53 is provided with a thread and is threadedly connected to the threaded hole 51a. One end of the driving member 53 penetrates through the threaded hole 51a and abuts against the base 10.

[0048] In this way, by threadedly connecting the driving member 53 and the threaded hole 51a, one end of the driving member 53 abuts against the base 10, and rotating the driving member 53 can drive the stretching body 51 to move away from the base 10, so that the second clamping assembly 70 tension the flexible substrate 2000. In this way, the moving precision is relatively high, and the stretching can be finely adjusted.

[0049] With reference to Figure 2 and Figure 3 In a possible implementation of the present application, the threaded hole 51a is spaced apart along the length direction of the stretching body 51, the driving member 53 is provided with a plurality of driving members 53, and the plurality of driving members 53 are one-to-one correspondingly arranged with the plurality of threaded holes 51a. The driving member 53 is a bolt.

[0050] By spacing a plurality of threaded holes 51a along the length direction of the stretching body 51, the plurality of driving members 53 can conveniently adjust the tensioning force of the different positions of the first side edge of the flexible substrate 2000. The driving member 53 is a bolt, which is a standard part, can effectively reduce the cost, and is convenient to screw and operate.

[0051] For example, three driving members 53 and three threaded holes 51a of the stretching body 51 can be arranged, compared with one driving member 53 and one threaded hole 51a of the stretching body 51, the tensioning force of the different positions of the flexible substrate 2000 can be adjusted. In actual application, two driving members 53 and two threaded holes 51a of the stretching body 51 can also be arranged, or other numbers of driving members 53 and the stretching body 51 can be arranged, and the number is greater than one.

[0052] With reference to Figure 3In a possible implementation of the present application, the base 10 is provided with sliding portions 11, the stretching body 51 is provided with sliding grooves 51b, the sliding portions 11 are inserted into the sliding grooves 51b and slide relative to the sliding grooves 51b. In this way, the stretching body 51 is connected to the base 10 in a sliding manner through the sliding cooperation between the sliding portions 11 and the sliding grooves 51b, and the sliding grooves 51b are stable and reliable in structure and easy to manufacture.

[0053] With reference to Figure 2 and Figure 3 In a possible implementation of the present application, the base 10 is in the form of a plate, and two sliding portions 11 are provided on the side of the base 10 away from the first clamping assembly 30. The two sliding portions 11 are arranged at intervals, and each sliding portion 11 extends in a direction away from the first clamping assembly 30. The stretching body 51 is located between the two sliding portions 11, and each side of the stretching body 51 opposite to the other side is provided with a sliding groove 51b. The openings of the two sliding grooves 51b are arranged opposite to each other, and the two sliding grooves 51b are arranged in one-to-one correspondence with the two sliding portions 11.

[0054] Since the rotational displacement of the two ends of the stretching body 51 is greater than the rotational displacement of the middle part of the stretching body 51 at the same rotational angle, and the two ends of the stretching body 51 are respectively provided with sliding grooves 51b, the distance between the two sliding grooves 51b is large, and the sliding grooves 51b are of the same precision. In this way, the stretching body 51 is less likely to rotate, and the stability of sliding is improved. In addition, the openings of the two sliding grooves 51b are arranged opposite to each other, that is, the first opening of the sliding groove 51b faces the sliding portion 11 close to it, and the second opening of the sliding groove 51b faces the sliding portion 11 close to it. In this way, the sliding portion 11 can be more easily inserted into the groove, thereby facilitating the installation of the stretching body 51 on the base 10.

[0055] With reference to Figure 2 and Figure 3 In a possible implementation of the present application, the first clamping assembly 30 is connected to the base 10 by means of bolts and clamps the first side of the flexible substrate 2000 together with the base 10. The second clamping assembly 70 is connected to the base 10 by means of bolts and clamps the second side of the flexible substrate 2000 together with the base 10. In this way, the clamping is achieved through the bolt connection, and the structure is simple and stable and reliable.

[0056] With reference to Figure 2 and Figure 3 In a possible implementation of the present application, one surface of the base 10 is concave and forms an installation groove, which forms an installation site 10a. In this way, the glass plate can be effectively positioned and installed.

[0057] With reference to Figure 2 and Figure 3In a possible implementation of the present application, the groove bottom of the mounting groove is provided with a plurality of lightening holes 10b. In this way, the lightening holes 10b not only reduce the weight of the entire flexible substrate clamping jig 100, but also save materials, thereby reducing costs.

[0058] The present application also provides a processing equipment 1000, which is combined with reference to Figure 2 Figure 3 Figure 4 The processing equipment 1000 includes a processing device 300 and a flexible substrate clamping jig 100. The processing device 300 is used to process a flexible perovskite battery. The flexible substrate clamping jig 100 is used to carry a flexible substrate 2000. The specific structure of the flexible substrate clamping jig 100 is referred to the above-mentioned embodiments. Since the processing equipment 1000 adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0059] The processing device 300 is used to process a flexible perovskite battery, which means adding materials on the flexible substrate 2000 to realize one of the processes of manufacturing a flexible perovskite battery. Specifically, it includes but is not limited to one or more of the following: laminating an electron transport layer, a perovskite light absorption layer, a hole transport layer, and a top electrode.

[0060] It can be understood that by using the flexible substrate clamping jig 100 to clamp the flexible substrate 2000, the flexible substrate 2000 does not need to be glued to a glass plate, nor does it need to be separated after the process. Therefore, the manufacturing efficiency of the flexible perovskite photovoltaic battery can be improved.

[0061] In an embodiment, the processing device 300 can be a coating device. In another embodiment, the processing device 300 can also be a deposition device. In other embodiments, the processing device 300 can also be other effective process devices.
