[0034] Example:

[0035] Flexible devices such as flexible solar cells need to undergo mechanical testing and photoelectric testing to characterize the fatigue resistance, stability and life attenuation characteristics of flexible solar cell samples. The test fixtures in related technologies have low reliability and will damage the thin-layer electrode structure of the cell samples when performing mechanical tests on flexible solar cell samples, resulting in the inability to stably transmit the electrical test data.

[0036] See also Figures 1 to 9 In this embodiment, a test fixture 10 for a flexible device 20 includes: two fixing components 100 whose heads are relatively fixed and an electrical test component 400 fixed on each fixing component 100, wherein the heads of the two fixing components 100 are used to fix the two ends of the flexible device 20 respectively; one end of the electrical test component 400 close to the head of the fixing component 100 has a conductive area 210, and the conductive area 210 is used to be electrically connected to the electrode of the flexible device 20; and one end of the electrical test component 400 close to the tail of the fixing component 100 is used to be flexibly connected to a power source.

[0037] The two ends of the flexible device 20 are the stress-bearing ends of the mechanical performance test. The two ends of the device are respectively fixed to the heads of the two fixed components 100 of the test fixture 10. By applying force to change the relative position between the two fixed components 100, the flexible device 20 is deformed by bending, stretching or twisting for mechanical testing. The two ends of the flexible device 20 are also electrically connected to the conductive area 210 on the electrical test component 400 near the head of the fixed component 100, and one end of the electrical test component 400 near the tail of the fixed component 100 is flexibly connected to the power supply. The conductive area 210 of the electrical test component 400 leads out the electrode at the stress limit position of the flexible device 20, so that the electrode of the flexible device 20 is separated from the stress point of the flexible device 20, so that the electrode position of the flexible device 20 is not limited by the pressure of the test fixture 10, thereby improving the stability of the electrical test of the flexible device 20. In addition, the test fixture 10 has a clever structure, a small size, and is easy to disassemble and assemble, and can be used to receive light sources at various angles.

[0038] Furthermore, if Figure 7 As shown, the fixing assembly 100 includes a first fixing member 110 and a second fixing member 120 fixedly connected to the first fixing member 110; the electrical test assembly 400 includes a circuit board 410 fixed to a side of the second fixing member 120 away from the first fixing member 110 and a conductive probe 420 protruding from the circuit board 410 toward the first fixing member 110, the conductive probe 420 has a conductive area 210, and the flexible device 20 is placed between the conductive probe 420 and the first fixing member 110.

[0039] In the first embodiment, if Figure 7As shown, the first fixing member 110 is provided with fixing protrusions 115 on both sides adjacent to the head of the fixing assembly 100, and the second fixing member 120 is a frame body with a hollow central area, and the two opposite frame walls of the second fixing member 120 are fixed between the two fixing protrusions 115 by threaded connection. In other embodiments, the first fixing member 110 and the second fixing member 120 can also select other detachable connection methods, such as a latch connection or a snap connection.

[0040] Furthermore, if Figure 6-7 As shown, in the first embodiment, the electrical test assembly 400 further includes an electrode adapter 430 fixed to an end of the circuit board 410 opposite to the conductive probe 420 , and the conductive probe 420 , the circuit board 410 and the electrode adapter 430 are electrically connected.

[0041] It can be known that the electrode adapter cable 430 can be assembled integrally with the electrical test assembly 400, and the electrode adapter cable 430 can also be pluggably connected to the circuit board 410. Different electrode adapter interfaces can be installed on the circuit board 410 according to different needs to replace different types of adapter cables.

[0042] In the first embodiment, if Figure 7 and Fig. 9 As shown, at the head of the fixing assembly 100 , the second fixing member 120 has a first pressing portion 121 protruding toward the first fixing member 110 , and the first pressing portion 121 is spaced apart from the conductive probe 420 ; the first pressing portion 121 and the first fixing member 110 are used to press and fix the flexible device 20 .

[0043] See also Figures 1 to 5 In a second embodiment, a test fixture 10 for a flexible device 20 includes: two fixing components 100 with heads arranged opposite to each other and a planar electrode 200 fixed on each fixing component 100; the heads of the two fixing components 100 are used to fix the two ends of the flexible device 20 respectively; one end of the planar electrode 200 close to the head of the fixing component 100 has a conductive area 210, and the conductive area 210 is used to be electrically connected to the electrode of the flexible device 20, and one end of the planar electrode 200 close to the tail of the fixing component 100 is used to be flexibly connected to a power source.

[0044] In the second embodiment, the two ends of the flexible device 20 are the force-bearing ends during the mechanical property test. The two ends of the device are respectively fixed to the heads of the two fixing components 100 of the test fixture 10. By applying force to change the relative position between the two fixing fixtures, the flexible device 20 is made to bend, stretch or twist to perform mechanical testing.

[0045] Both ends of the flexible device 20 are also electrically connected to the conductive area 210 on the planar electrode 200 near the head of the fixed component 100, and one end of the planar electrode 200 near the tail of the fixed component 100 is flexibly connected to the power supply. On the one hand, the conductive area 210 of the planar electrode 200 leads out the electrode at the force limit position of the flexible device 20, so that the electrode of the flexible device 20 is separated from the force point of the flexible device 20, so that the electrode position of the flexible device 20 is not limited by the pressure of the test fixture 10, and the stability of the electrical test of the flexible device 20 is improved; on the other hand, the planar electrode 200 is flexibly connected to the power supply, which is softer and more stable in contact than ordinary connecting wires, and has little effect on the data of the mechanical test under mechanical testing. At the same time, the test fixture 10 has a clever structure, a small size, and is easy to disassemble and assemble, and can be used to receive light sources at various angles.

[0046] Furthermore, the fixing assembly 100 includes a first fixing member 110 and a second fixing member 120 fixedly connected to the first fixing member 110, the planar electrode 200 is fixed between the first fixing member 110 and the second fixing member 120, and the flexible device 20 is placed between the conductive area 210 of the planar electrode 200 and the second fixing member 120. Figure 1~2 As shown, the first fixing member 110 and the second fixing member 120 and the connection method thereof in the second embodiment are similar to those in the first embodiment and will not be described in detail herein.

[0047] Furthermore, if Figure 2 As shown, the second fixing member 120 has a first pressing portion 121 protruding toward the conductive area 210 of the planar electrode 200 ; the first pressing portion 121 and the conductive area 210 are used to press and fix the flexible device 20 so that the electrode of the flexible device 20 is electrically connected to the conductive area 210 .

[0048] In the second embodiment, if Figure 2 As shown, the conductive area 210 includes a plurality of square areas, the surface of each square area is a conductive material, and the plurality of square areas are used to fit the electrodes of the flexible device 20. The probe used by the test fixture 10 in the related art to contact the electrodes of the flexible device 20 is relatively thin, and the contact area with the electrodes of the flexible device 20 is very small. However, in the test fixture 10 provided by the utility model, the conductive area 210 of the planar electrode 200 has a large contact area with the electrodes of the flexible device 20, which reduces the pressure when the traditional probe contacts the electrodes of the flexible device 20, reduces the risk of piercing the electrodes, and improves the reliability of the test fixture 10.

[0049] In the second embodiment, further, as Figure 1As shown, the first pressing part 121 includes a plurality of pressing protrusions matching the plurality of square areas, preferably, the projection of the pressing protrusion in the direction perpendicular to the conductive area 210 covers the corresponding square area, and the cross section of the pressing protrusion in the direction perpendicular to the conductive area 210 is arc-shaped. The pressing protrusion with an arc-shaped cross section can not only play the role of pressing and fixing the flexible device 20, but also reduce the pressure on the electrode surface of the flexible device 20 during pressing, thereby preventing the electrode of the flexible device 20 from being damaged and affecting the electrical test data.

[0050] As an example, Figure 1 As shown, the first pressing part 121 in this embodiment includes four pressing protrusions. In other embodiments, the square area with the conductive material on the surface can also be a circle, a strip or other shapes, which can be designed according to the electrode of the tested flexible device 20. It can be known that the number and shape of the pressing protrusions of the first pressing part 121 also have more choices, including but not limited to continuous or discontinuous columns, etc. Figures 6 to 9 In the first embodiment shown, see Fig. 9 The pressing protrusion of the first pressing portion 121 is a continuous strip.

[0051] It should be known that the conductive area 210 of the planar electrode 200 is provided with conductive materials on both side surfaces facing the first fixing member 110 and the second fixing member 120 and is electrically connected to form electrodes. That is to say, the flexible device 20 can be fixed not only between the first fixing member 110 and the planar electrode 200, but also between the second fixing member 120 and the planar electrode 200. Both methods can separate the electrode of the flexible device 20 from the deformation stress point of the flexible device 20 during the mechanical test, while ensuring a larger contact area between the planar electrode 200 and the flexible device 20, thereby reducing the risk of damage to the electrode of the flexible device 20.

[0052] Furthermore, the test fixture 10 also includes an electrode transfer lead 300 electrically connected to the planar electrode 200, and an electrode transfer interface 220 is provided at one end of the planar electrode 200 opposite to the conductive area 210, one end of the electrode transfer lead 300 is plugged into the electrode transfer interface 220, and the other end of the electrode transfer lead 300 is used to be electrically connected to an external power supply. In the second embodiment, the electrical test of the flexible device 20 requires connecting the electrode lead of the flexible device 20 to an electric meter. The test fixture 10 in the utility model achieves mechanical and electrical separation by introducing the planar electrode 200, and the end of the planar electrode 200 that is not subjected to force is connected to the electrode transfer lead 300, so that the transmission of the electrical signal is more stable, and the influence of the mechanical test on the electrical test data is reduced.

[0053] Furthermore, if Figure 2 and Figure 5As shown, the fixing assembly 100 further includes a third fixing member 130 fixedly connected to the first fixing member 110 on a side close to the second fixing member 120 , and the planar electrode 200 is at least partially fixed between the first fixing member 110 and the third fixing member 130 .

[0054] In the second embodiment, the third fixing member 130 further fixes the planar electrode 200, reduces the interference of the movement of the planar electrode 200 on the test data during the test, and improves the reliability of the test fixture 10. It should be known that when the test fixture 10 in the first embodiment is equipped with the planar electrode 200, the third fixing member 130 is also applicable to the first embodiment.

[0055] Furthermore, the first fixing member 110 is provided with a fixing groove 111 opening toward the third fixing member 130, and the opening of the fixing groove 111 toward the third fixing member 130 is connected to the groove wall of the fixing groove 111 close to the conductive area 210, and the third fixing member 130 has a second pressing portion 131 protruding toward the fixing groove 111, and the planar electrode 200 is pressed and fixed to the groove bottom of the fixing groove 111 by the second pressing portion 131.

[0056] In the second embodiment, if Figure 2 As shown, the shape of the third fixing member 130 matches the planar electrode 200. Specifically, an avoidance groove matching the electrode adapter interface 220 is provided at one end of the third fixing member 130 close to the electrode adapter interface 220. The third fixing member 130 except for the second pressing portion 131 is threadedly connected to the first fixing member 110. It should be known that in other embodiments, the third fixing member 130 can also be fixed to the first fixing member 110 by a detachable connection method such as a pin connection or a snap connection.

[0057] Figure 4 The test fixture 10 of this embodiment is Figure 3 Cross-sectional view along the AA direction, Figure 5 for Figure 4 For an enlarged view of detail B, see Figure 5 The bottom of the fixing groove 111 to the end of the first fixing member 110 away from the conductive area 210 is an inclined surface, so that the connection is more secure when the electrode adapter lead 300 is plugged into the electrode adapter interface 220.

[0058] Furthermore, the bottom of the fixing groove 111 at one end close to the conductive region 210 of the planar electrode 200 is the flexible substrate 112 .

[0059] Specifically, Figure 5As shown, in the second embodiment, the flexible substrate 112 is a silicone pad, and a groove is provided in the groove body of the fixing groove 111 near the conductive region 210 of the planar electrode 200, and the silicone pad is received and fixed in the groove, and the side of the silicone pad away from the groove bottom is flush with the groove bottom of the fixing groove 111. During use, the flexible substrate separates the conductive region 210 of the planar electrode 200 and the first fixing member 110 as a buffer, thereby protecting the conductive region 210 of the planar electrode 200. In other embodiments, the flexible substrate 112 can be arranged at the groove bottom of the fixing groove 111 near the conductive region 210, and as in the first embodiment, a silicone pad can also be arranged at the groove bottom of the fixing groove 111 near the conductive probe 420.

[0060] Furthermore, if Figure 2 As shown, the planar electrode 200 is provided with a positioning hole 230 , and the first fixing member 110 is provided with a positioning member 113 matching the positioning hole 230 protruding toward the planar electrode 200 , and the positioning member 113 is passed through the positioning hole 230 .

[0061] In the second embodiment, a positioning hole 230 is provided at the center of the planar electrode 200, and the positioning hole 230 is located between the conductive area 210 and the electrode adapter interface 220. Another avoidance groove matching the positioning column is provided at one end of the third fixing member 130 close to the positioning column. Specifically, the positioning member 113 is located in the fixing groove 111, and the positioning member 113 is a column. The outer periphery of the positioning member 113 is closely fitted with the inner edge of the positioning hole 230, and the positioning member 113 can be embedded in the positioning hole 230, so that the planar electrode 200 is stably fixed in the fixing groove 111.

[0062] In other embodiments, the positioning member 113 can also be other parts that can fix the planar electrode 200, not limited to a column, such as a snap-on part bent toward the outside of the positioning hole 230 so that the planar electrode 200 can be snapped onto the positioning member 113, or a magnetic part is provided on the first fixing member 110 to fix the planar electrode 200 by magnetic attraction, etc.

[0063] Furthermore, the electrode transfer lead 300 is a flexible flat cable.

[0064] Flexible Flat Cable, referred to as soft cable, has the advantages of being soft, able to be bent and folded at will, thin, small in size and easy to disassemble compared to ordinary connecting wires. In the test of the flexible device 20, the electrical connection between the soft cable and the planar electrode 200 is more stable and has less impact on the test data.

[0065] Furthermore, if Figure 3As shown, the first fixing member 110 has mounting portions 114 on both sides of the end portion close to the electrode adapter interface 220 , and the length extension direction of the mounting portion 114 is perpendicular to the plugging direction of the electrode adapter lead 300 .

[0066] Specifically, the plugging direction of the electrode transfer lead 300 is as follows: Figure 4 As shown, the first fixing members 110 of the two fixing assemblies 100 both have an assembly portion 114, which can be fixedly connected to an external bending and torsion tester. The assembly portion 114 is arranged on both sides of the end of the first fixing member 110 close to the electrode adapter interface 220, away from the conductive area 210 of the planar electrode 200, further reducing the impact of the mechanical test force on the electrode of the flexible device 20 electrically connected to the conductive area 210, ensuring the stability of the test data and improving the reliability of the test fixture 10.

[0067] It can be known that a planar electrode 200 can also be added to the first embodiment. When the planar electrode 200 in the second embodiment is applied to the first embodiment, the structure of the planar electrode 200 should be changed accordingly. For example, the planar electrode 200 applied to the first embodiment only includes a conductive area 210 but does not include an electrode adapter interface 220. The planar electrode 200 is placed between the conductive probe 420 and the flexible device 20 to play a protective role.

[0068] The above is only a preferred embodiment of the present invention. The different technical features and technical solutions in the above multiple embodiments can be combined and replaced with each other, and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
