[0002] In photovoltaic (PV) modules, reflective film strips are typically used to increase the module's light utilization efficiency, thereby improving its output power. Reflective film strips usually have a four-layer structure consisting of a base layer, a structural layer, an adhesive layer, and a reflective layer. During the PV module manufacturing process, the peel strength of the reflective film strips needs to be tested.

However, this method suffers from difficulty in accurately controlling the peel angle, resulting in low accuracy. Furthermore, repeated experiments are susceptible to human error, leading to low repeatability. Utility Model Content

[0029] The aforementioned peel test device is suitable for testing the peel force of reflective film strips.

It provides accurate control of the peel angle and reduces the error of the peel angle in each repeated experiment, thus improving the repeatability of the test. In other words, the peel testing device of this application is suitable for peel testing of reflective film strips in photovoltaic modules, improving the accuracy and repeatability of the test results.
[0030] Understandable, Figure 1 , Figure 2 The description of the peel testing apparatus mentioned above mentions the sample 20 to be tested, but the sample 20 is not a component of the peel testing apparatus. The above description of the peel testing apparatus is only to illustrate the cooperation relationship between the sample 20 to be tested and the peel testing apparatus of this application. Meanwhile, the test piece can be disposed inside the main body of the apparatus, therefore... Figure 1 , Figure 2 Not shown in the image.
[0031] Refer again Figure 1 , Figure 2 As shown, exemplarily, Figure 1 , Figure 2 The X direction in the diagram is the first direction.
[0032] In some embodiments, the depth of the sample groove 12 is 2 mm to 3 mm.
[0033] Optionally, the depth of the sample well 12 is 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm or 3 mm, or the depth of the sample well 12 can be within any two of the above depths.
[0034] In some embodiments, the connecting end of the sample connector 31 extends in the opposite direction to the first direction and protrudes from the device body.
[0035] The connecting end of the sample connector 31 extends in the opposite direction of the first direction and protrudes from the main body of the device, so as to facilitate the connection of the part to be peeled in the sample 20 to be tested through the connecting end, and the part to be peeled in the sample 20 to be tested is peeled and tested by the pulling device 30 moving in the slide 11 along the first direction.
[0036] In some embodiments, the connecting end of the sample connector 31 protrudes from the main body of the device in the opposite direction of the first direction by a length of 10mm to 15mm.
[0037] Optionally, the length of the connecting end of the sample connector 31 protruding from the main body of the device in the opposite direction of the first direction is 10mm, 11mm, 12mm, 13mm, 14mm or 15mm. Alternatively, the length of the connecting end of the sample connector 31 protruding from the main body of the device in the opposite direction of the first direction can also be within the range of any two of the above lengths.
[0038] In some embodiments, the pulling device 30 further includes a gripper 32. The gripper 32 is disposed on and protrudes from the device body, and is used to grip the pulling device 30.
[0039] The gripper 32 allows for easy gripping of the pulling device 30 and movement of the pulling device 30 along the first direction within the slide 11.
[0040] In some embodiments, the grip 32 extends in the positive direction of the first direction and protrudes from the device body.
[0041] The grip 32 extends along the positive direction of the first direction and protrudes from the main body of the device, so that the grip 32 can be used to easily grip the pulling device 30 and move it along the first direction within the slide 11 to pull the pulling device 30.
[0042] In some embodiments, there are multiple sample connectors 31. The connecting ends of the multiple sample connectors 31 are arranged at intervals along a second direction, which is different from the first direction.
[0043] Refer again Figure 1 , Figure 2 As shown, exemplarily, Figure 1 , Figure 2 The Y direction in the equation is the second direction.
[0044] The connecting ends of multiple sample connectors 31 are arranged at intervals along the second direction. The pull device 30 can simultaneously perform peeling tests on multiple parts of the sample 20 to be peeled by moving it once in the slide 11 along the first direction, and can ensure that the error of the peeling angle is small, thus achieving highly efficient repeatable experiments.
[0045] In some implementations, the second direction is perpendicular to the first direction.
[0046] In some embodiments, the width of the sample groove 12 along the second direction is smaller than the width of the slide 11 along the second direction.

[0048] Optionally, the width of the sample groove 12 along the second direction is 200mm, 220mm, 250mm, 280mm, 300mm, 320mm, 350mm, 380mm or 400mm, or the width of the sample groove 12 along the second direction can be within the range of any two of the above widths.

[0051] In some embodiments, a positioning mark is provided on the side wall of the slide 11. The tension device 30 also includes a positioning member 34, which is disposed on the side wall of the device body parallel to the first direction. The positioning member 34 and the positioning mark 13 can cooperate to position the tension device 30 in the slide 11.
[0052] In some embodiments, a release film layer is also provided on the surface of the tension device 30 facing the base 10.
[0053] A release film layer is also provided on the surface of the tension device 30 facing the base 10, so that the reflective film strip in the sample 20 to be tested can still be separated from the tension device 30 normally after high temperature treatment.
[0054] In some embodiments, the tensile device 30 further includes a display element 33. The display element 33 is disposed on the device body and electrically connected to the test specimen. The display element 33 is used to display the test results of the test specimen.
[0055] In some embodiments, the display 33 is located on the surface of the device body away from the base 10.

The sample connector 31 has a connecting end protruding from the device body, which is used to connect the peelable portion of the sample 20. The connecting end of the sample connector 31 extends in the opposite direction of the first direction and protrudes from the device body. The tension device 30 also includes a gripping member 32, which is disposed on the device body and protrudes from the device body, and is used to grip the tension device 30. In this embodiment, the gripper 32 extends along the positive direction of the first direction and protrudes from the main body of the device. In this embodiment, there are five sample connectors 31, with their connecting ends spaced apart along a second direction, which is perpendicular to the first direction. The width of the sample groove 12 along the second direction is less than the width of the slide rail 11 along the second direction. A positioning mark is provided on the side wall of the slide rail 11. The tension device 30 also includes a positioning member 34, which is disposed on the side wall of the main body of the device parallel to the first direction.
