Their main function is to directly convert light energy into electrical energy using the photovoltaic effect. Photovoltaic modules are composed of various materials, including tempered glass, solar cells, ethylene-vinyl acetate copolymer, backsheet, solder ribbon, silicone, junction box, and frame. Among these materials, tempered glass plays a crucial role. It is mainly used at the front of the photovoltaic module as a protective and supporting structure. Before installing the photovoltaic module, it is very necessary to conduct physical property tests on the tempered glass to determine whether it meets the specified standards, such as compressive strength tests and abrasion resistance tests.

[0003] A comprehensive tester for photovoltaic modules disclosed in a patent application with the reference number CN118549348A can convey the solar cells of the photovoltaic module through a conveyor belt and clamp them through a clamping component. Then, the comprehensive test component can test the peel force, compressive force, and impact resistance of the solar cells. After the test is completed, the visual test device can observe the appearance of the solar cells to determine whether the solar cells are damaged after being tested by the comprehensive test component.

[0019] Beneficial effects

[0020] The present invention provides a comprehensive tester for photovoltaic modules. Compared with the prior art, the following beneficial effects are achieved:

[0021] (1) The integrated photovoltaic module tester, through the mutual cooperation among the integrated test seat mechanism, the rotating shaft, and the function disc mechanism, places the tempered glass in the raw materials of the photovoltaic module into each integrated test seat mechanism in sequence to limit the tempered glass. Then, the servo motor is started to drive the rotation of the rotating shaft and the function disc mechanism. During the rotation of the function disc mechanism, each integrated test seat mechanism can be driven to work intermittently, and the compressive strength and wear resistance of the tempered glass in the integrated test seat mechanism can be comprehensively tested simultaneously. Moreover, multiple tempered glasses can be tested within the same cycle, significantly improving the test efficiency.

[0022] (2) The integrated photovoltaic module tester, through the mutual cooperation among the first slider, the test frame assembly, the push frame assembly, and the wedge block, places the tempered glass at the middle of the inner cavity bottom of the U-shaped seat and limits it with two pressing plates. Then, the servo motor is started to drive the revolution of each wedge block. During the rotation of the wedge block, since the two sides of the wedge block are symmetrically provided with inclined surfaces to provide a movement track for the movement of the semi-circular block, under the pushing action of the wedge block and the elastic action of the third spring, the semi-circular block moves up and down multiple times, so that the push rod moves up and down multiple times. During the downward movement of the push rod, the purpose of pushing the two test frame assemblies downward and separating the two test frame assemblies from each other is achieved, so as to simultaneously perform extrusion and friction tests on the surface of the tempered glass below. Two different test effects can be achieved in one operation action, and under the action of multiple wedge blocks, the compressive strength and wear resistance of the tempered glass can be comprehensively tested multiple times in a short time.

[0023] (3) The integrated photovoltaic module tester, through the mutual cooperation among the connecting rod, the downward pressing cylinder body, the friction plate, and the first bolt, can paste the three commonly used friction plates on the outside of the corresponding downward pressing cylinder body in advance by using the magic velour surface. Then, according to the working environment to which the tempered glass to be tested is to be applied, the friction plate with the required friction coefficient can be quickly switched to flexibly adjust the friction test parameters. The corresponding downward pressing cylinder body is switched to the lowest position, and then the position of the downward pressing cylinder body is limited by the first bolt, and the wear resistance of the tempered glass surface is tested by using the corresponding friction plate. Different working conditions in different scenarios can be simulated to test whether the tempered glass can meet the wear resistance requirements in the corresponding environment. The applicable range is relatively wide, and the severely worn friction plate can be flexibly replaced to ensure normal test use later.

[0024] (4) The integrated photovoltaic module tester can, through the mutual cooperation among the top plate, the wedge block, the limiting hole and the second bolt, 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 applied. By using the wedge block extending below the top plate, the semi-circular block is pushed within a specified height range, thereby pushing the downward pressing cylinder downward by a specified distance to extrude the surface of the tempered glass, realizing the compressive strength test of the surface of the tempered glass. Since the greater the distance the downward pressing cylinder moves downward, the stronger the extrusion force on the surface of the tempered glass, by adjusting the height of the wedge block extending below the top plate, the flexible adjustment of the extrusion test parameters can be achieved, and the working conditions in different scenarios can be simulated to test whether the tempered glass can meet the compressive strength requirements in the corresponding environment, further expanding the scope of application.

[0046] Such as Figures 4 to 14The second implementation mode is shown. The main difference from the first implementation mode lies in: a comprehensive photovoltaic module tester. Each comprehensive test seat mechanism 3 includes a U-shaped seat 31. The U-shaped seat 31 is fixedly connected to the top of the chassis 2. Chute grooves 32 are opened at the front, rear, both sides of the U-shaped seat 31. A first slider 33 is slidably arranged in each chute groove 32. First springs 34 are fixedly arranged at the mutually remote ends of the two first sliders 33 on the same side. The ends of the first springs 34 remote from the first sliders 33 are fixedly connected to the inner walls of the chute grooves 32. A test frame assembly 35 is fixedly arranged between the two first sliders 33 at the front and between the two first sliders 33 at the rear. The two test frame assemblies 35 are symmetrically arranged. A pushing frame assembly 36 is arranged on the top of the chassis 2 and above the two test frame assemblies 35.

A downward pressing cylinder assembly 356 is rotatably arranged between the two side plates 355. The lower parts of the mutually remote sides of the two side plates 355 and the downward pressing cylinder assembly 356 are threadedly connected through first bolts 357. Triangular blocks 358 are fixedly arranged at both sides of the top of the connecting plate 354. The downward pressing cylinder assembly 356 includes a connecting rod 3561. The connecting rod 3561 is rotatably connected between the two side plates 355. Carrying frames 3562 are fixedly sleeved on both outer sides of the connecting rod 3561. Three downward pressing cylinders 3563 are rotatably arranged between the two carrying frames 3562. The three downward pressing cylinders 3563 are evenly distributed in a circle outside the connecting rod 3561. A circle of magic tape hook surfaces 3564 is fixedly arranged on the outside of each downward pressing cylinder 3563. A friction plate 3566 is detachably arranged on the outside of each magic tape hook surface 3564 through a magic tape plush surface 3565. The friction coefficients of the three friction plates 3566 are different. Side discs 3567 are fixedly sleeved on both outer sides of the connecting rod 3561. The side discs 3567 are located between the corresponding carrying frames 3562 and the corresponding side plates 355. Three positioning holes 3568 are evenly opened in a circle outside the side discs 3567. The first bolts 357 threadedly penetrate between the side plates 355 and the interiors of the corresponding positioning holes 3568. The pushing frame assembly 36 includes an L-shaped frame 361. The L-shaped frame 361 is fixedly connected to the top of the chassis 2 and above the U-shaped seat 31.A vertical rod 362 slides through the top of the L-shaped frame 361 and is located directly above the horizontal plate 38. A connecting frame 363 is fixedly arranged at the bottom of the vertical rod 362. Two U-shaped frames 364 are fixedly arranged at the bottom of the connecting frame 363 and are respectively located above the corresponding connecting plates 354. Push rods 365 are rotatably arranged between the two side walls of the inner cavities of the two U-shaped frames 364. The two push rods 365 are respectively located between the upper parts of the front two triangular blocks 358 and between the upper parts of the rear two triangular blocks 358. A semi-circular block 366 is fixedly arranged at the top of the vertical rod 362. A third spring 367 is sleeved on the outside of the vertical rod 362. The third spring 367 is fixedly connected between the top of the L-shaped frame 361 and the bottom of the semi-circular block 366. The function disc mechanism 5 includes a top disc 51. The middle of the bottom of the top disc 51 is fixedly connected to the top of the rotating shaft 4. A number of wedge-shaped blocks 52 slide through the outer circumference of the top disc 51 evenly. A number of limit holes 53 are evenly arranged from top to bottom on the mutually remote sides of the number of wedge-shaped blocks 52. A number of scale lines are evenly arranged from top to bottom on the mutually remote sides of the number of wedge-shaped blocks 52. Each wedge-shaped block 52 is threadedly connected to the top disc 51 through a second bolt 54. The second bolt 54 threadedly penetrates between the side wall of the top disc 51 and the inside of the corresponding limit hole 53.,

[0047] Through the mutual cooperation among the first slider 33, the test frame assembly 35, the pushing frame assembly 36 and the wedge block 52, the tempered glass is placed in the middle of the inner cavity bottom of the U-shaped seat 31 and limited by two pressing plates 39. Then, starting the servo motor can drive each wedge block 52 to revolve. During the rotation of the wedge block 52, since the two sides of the wedge block 52 are symmetrically provided with inclined surfaces, a movement track is provided for the movement of the semi-circular block 366. Under the pushing action of the wedge block 52 and the elastic action of the third spring 367, the semi-circular block 366 moves up and down multiple times, so that the push rod 365 moves up and down multiple times. During the downward movement of the push rod 365, the purpose of pushing the two test frame assemblies 35 downward and making the two test frame assemblies 35 move away from each other is achieved, so as to simultaneously perform extrusion and friction tests on the surface of the tempered glass below. Two different test effects can be achieved in one operation action, and under the action of multiple wedge blocks 52, the comprehensive tests of the compressive strength and wear resistance of the tempered glass can be carried out multiple times in a short time. Through the mutual cooperation among the connecting rod 3561, the pressing cylinder body 3563, the friction plate 3566 and the first bolt 357, the three commonly used friction plates 3566 can be pasted on the outside of the corresponding pressing cylinder body 3563 by using the magic velour surface 3565 in advance. Then, according to the working environment to which the tempered glass to be tested is applied, the friction plate 3566 with the required friction coefficient can be quickly switched, and the corresponding pressing cylinder body 3563 is switched to the lowest position. Then, the position of the pressing cylinder body 3563 is limited by the first bolt 357, and the wear resistance test of the tempered glass surface is carried out by using the corresponding friction plate 3566. Different working conditions in different scenarios can be simulated to test whether the tempered glass can meet the wear resistance requirements in the corresponding environment. The applicable range is relatively wide, and the severely worn friction plates 3566 can be flexibly replaced to ensure normal test use thereafter. Through the mutual cooperation among the top plate 51, the wedge block 52, the limiting hole 53 and the second bolt 54, the height of the wedge block 52 extending below the top plate 51 can be flexibly adjusted according to the working environment to which the tempered glass to be tested is applied. By using the wedge block 52 extending below the top plate 51, the semi-circular block 366 is pushed within a specified height range, so as to push the pressing cylinder body 3563 downward by a specified distance and perform extrusion on the surface of the tempered glass, realizing the compressive strength test on the surface of the tempered glass. Since the greater the downward movement distance of the pressing cylinder body 3563, the stronger the extrusion force on the surface of the tempered glass, by adjusting the height of the wedge block 52 extending below the top plate 51, different working conditions in different scenarios can be simulated to test whether the tempered glass can meet the compressive strength requirements in the corresponding environment, further expanding the applicable range.

[0048] At the same time, the content not described in detail in this specification belongs to the prior art well 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,It indicates that the tempered glass can meet the compressive and wear-resistant requirements in the corresponding environment.
