[0019] Beneficial Effects

[0020] The present invention provides a photovoltaic module comprehensive tester. Compared with the prior art, it has the following beneficial effects:

[0021] (1) The photovoltaic module comprehensive tester, through the mutual cooperation between the comprehensive test seat mechanism, the rotating shaft and the functional disk mechanism, places the tempered glass in the raw materials of the photovoltaic module in each comprehensive test seat mechanism in turn, limits the tempered glass, and then starts the servo motor to drive the rotating shaft and the functional disk mechanism to rotate. During the rotation of the functional disk mechanism, each comprehensive test seat mechanism can be driven to work intermittently, and the tempered glass in the comprehensive test seat mechanism can be tested for compressive strength and wear resistance at the same time. In addition, multiple tempered glasses can be tested in the same cycle, which significantly improves the test efficiency.

[0022] (2) The photovoltaic module comprehensive tester places the tempered glass in the middle of the bottom of the inner cavity of the U-shaped seat through the mutual cooperation between the first slider, the test frame assembly, the push frame assembly and the wedge block, and limits it with two pressure plates. Then, the servo motor is started to drive each wedge block to revolve. During the rotation of the wedge block, since the two sides of the wedge block are symmetrically provided with inclined surfaces, a motion track is provided for the movement of the semicircular block. Under the pushing action of the wedge block and the elastic action of the third spring, the semicircular block moves multiple times in the up and down direction, thereby causing the push rod to move multiple times in the up and down direction. During the downward movement of the push rod, the two test frame assemblies are pushed downward and the two test frame assemblies are moved away from each other, thereby simultaneously performing extrusion and friction tests on the tempered glass surface below. Two different test effects can be achieved in one operation, and under the action of multiple wedge blocks, the tempered glass can be subjected to multiple comprehensive compressive strength and wear resistance tests in a short time.

[0023] (3) The photovoltaic module comprehensive tester can use the Velcro velvet surface to stick the three commonly used friction plates on the outside of the corresponding pressing cylinder in advance through the mutual cooperation among the connecting rod, the pressing cylinder, the friction plate and the first bolt. Then, according to the working environment in which the tempered glass to be tested is to be used, the friction plate with the required friction coefficient can be quickly switched to achieve flexible adjustment of the friction test parameters. The corresponding pressing cylinder is switched to the bottom, and then the position of the pressing cylinder is limited by the first bolt. The wear resistance of the tempered glass surface is tested using the corresponding friction plate. It can simulate working conditions in different scenarios and test whether the tempered glass can meet the wear resistance requirements in the corresponding environment. It has a wide range of applications and can flexibly replace the severely worn friction plate to ensure normal test use afterwards.

[0024] (4) The photovoltaic module comprehensive tester can flexibly adjust the height of the wedge block extending below the top plate according to the working environment in which the tempered glass to be tested is to be used, through the mutual cooperation between the top plate, the wedge block, the limit hole and the second bolt. The wedge block extending below the top plate is used to push the semicircular block within a specified height range, thereby pushing the downward pressure cylinder downward a specified distance to squeeze the surface of the tempered glass, thereby achieving a compressive strength test on the surface of the tempered glass. Since the greater the downward distance of the downward pressure cylinder, the stronger the squeezing force on the surface of the tempered glass, by adjusting the height of the wedge block extending below the top plate, the extrusion test parameters can be flexibly adjusted, thereby simulating working conditions in different scenarios, testing whether the tempered glass can meet the compressive strength requirements in the corresponding environment, and further expanding the scope of application.

[0048] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0049] When in use, multiple tempered glasses to be tested in the raw materials of the photovoltaic module are placed in each comprehensive test seat mechanism 3 in turn, and then the tempered glasses are limited. During the process, the tempered glass is placed in the middle of the bottom of the inner cavity of the U-shaped seat 31, and then the threaded rod 310 is screwed to push the pressure plate 39 downward, and at the same time, the pressure plate 39 slides along the corresponding vertical groove 37, and finally the tempered glass is limited by two pressure plates 39. The two pressure plates 39 are respectively located on both sides of the middle of the tempered glass. Then the servo motor is started to drive the rotating shaft 4 and the functional disk mechanism 5 to rotate. During the rotation of the functional disk mechanism 5, each wedge block 52 revolves accordingly. Since the inclined surfaces are symmetrically arranged on both sides of the wedge block 52, a motion track is provided for the movement of the semicircular block 366. The rotation of the wedge block 52 When the inclined surface of the wedge block 52 contacts the top of the semicircular block 366, the semicircular block 366 is gradually pushed downward. When the bottom of the wedge block 52 contacts the top of the semicircular block 366, the semicircular block 366 remains at the horizontal height for a certain period of time. When the inclined surface of the other side of the wedge block 52 contacts the top of the semicircular block 366, and under the elastic action of the third spring 367, the semicircular block 366 gradually moves upward. When the semicircular block 366 moves in the up and down direction, it can drive the vertical rod 362 and the connecting frame 363 to move, so that the push rod 365 moves in the up and down direction accordingly. When the push rod 365 moves downward, it will contact the inclined surfaces of the two adjacent triangular blocks 358. The two push rods 365 act on the two test frame assemblies 35 respectively. Under the elastic action of the first spring 34 and the second spring 353, the two connecting plates 354 can be pushed downward and the two connecting plates 354 can be moved away from each other. The two pressing cylinder assemblies 356 are pushed downward accordingly, and the two pressing cylinder assemblies 356 are moved away from each other. The pressing cylinder body 3563 located at the bottom of the pressing cylinder assembly 356 is used to squeeze the tempered glass surface below to achieve the compressive strength test of the tempered glass surface. Since the outer circle of the pressing cylinder body 3563 is pasted with a friction plate 3566, wherein the friction plate 3566 can be an elastic metal sheet, a special wear-resistant coating or cloth coated on a flexible substrate, etc., the pressing cylinder body 3563 can press the tempered glass. While the glass surface is being squeezed, the friction plate 3566 thereon will move along the tempered glass surface to test the wear resistance of the tempered glass surface, thereby achieving a comprehensive test of the compressive strength and wear resistance of the tempered glass at the same time. By adjusting the height of the wedge block 52 extending below the top plate 51 and switching the friction plate 3566 with a corresponding friction coefficient, working conditions in different scenarios can be simulated, such as deserts, mountainous areas or plains. Different areas may cause different degrees of squeezing and wear on the tempered glass surface, and whether the tempered glass can meet the compression and wear resistance requirements in the corresponding environment is tested. After the test, the sealed door 7 is opened to observe whether there are obvious wear marks, cracks or breakage on the tempered glass surface. If the above situation does not occur,This means that tempered glass can meet the requirements of pressure resistance and wear resistance in the corresponding environment.
