Description

Technical Field

[0001] This utility model relates to the field of hardness testing technology in photovoltaic production, specifically a hardness testing device for photovoltaic production with a pressing function. Background Technology

[0002] Solar photovoltaic, also known as photovoltaic, or simply photovoltaic, refers to facilities that convert solar energy into direct current (DC) electricity using the photovoltaic effect of photovoltaic semiconductor materials. The core of a photovoltaic facility is the solar panel. Currently, the main semiconductor materials used for power generation include monocrystalline silicon, polycrystalline silicon, amorphous silicon, and cadmium telluride. Due to the active promotion of renewable energy applications by various countries in recent years, the photovoltaic industry has developed rapidly. Photovoltaic systems can be installed on a large scale on the ground to form photovoltaic power plants, or they can be placed on the rooftops or exterior walls of buildings to form building-integrated photovoltaics (BIPV).

[0003] In the photovoltaic panel production process, it is necessary to test the hardness of the photovoltaic panel encapsulation materials (such as glass, backsheet, etc.) to help determine their physical properties such as scratch resistance. Usually, physical extrusion is used to determine their deformation. However, existing hardness testing devices are basically fixed structures, most of which do not have a clamping function, and the position of the clamping structure cannot be adjusted according to the size of the material being tested and the clamping range required for testing, resulting in inconvenience in use. Based on this, a hardness testing device for photovoltaic production with a clamping function is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a hardness testing device for photovoltaic production with a pressing function, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A hardness testing device for photovoltaic production with a pressing function, comprising a workbench, four pillars fixedly installed on the top of the workbench, a top plate fixedly installed on the top of the four pillars, a hydraulic telescopic rod one fixedly installed on the bottom of the top plate, a bracket fixedly installed on the output end of the hydraulic telescopic rod one, a sliding plate fixedly installed on the bottom end of the bracket, sliding sleeves fixedly fitted on the inner sides of the four corners of the sliding plate, a hydraulic telescopic rod two fixedly installed on the bottom surface of the top of the bracket, a through hole opened in the middle of the sliding plate, the hydraulic telescopic rod two extending through the through hole to the bottom of the sliding plate, and a Rockwell hardness tester fixedly installed on the output end of the hydraulic telescopic rod two. The pressure head has four sliding frames slidably fitted onto the outer sides of the four pillars. Four concave frames are fixedly installed at the diagonal inner sides of the sliding frames. Convex rods are slidably fitted onto the inner sides of the opposite ends of the four concave frames. Ring blocks are fixedly installed at the opposite ends of the convex rods. A third rubber friction pad is fixedly installed at the bottom of the ring blocks. A support rod is fixedly installed at the top of the ring blocks. A slider is fixedly installed at the top of the support rod. A sliding frame is slidably installed on the outer side of the slider. A second rubber friction pad is fixedly installed at the bottom of the concave frames. A first rubber friction pad is fixedly installed at the bottom of the convex rod. A set screw is threaded through the top of the four concave frames at the ends away from the sliding frames. A reinforcing rod is fixedly installed at the top of each of the four concave frames.

[0006] Preferably, the sliding sleeve is movably fitted onto the outside of the support column.

[0007] Preferably, the sliding frame is fixedly installed on the bottom of the skateboard.

[0008] Preferably, the bottoms of the concave frame and the convex rod are on the same plane, and the bottoms of the first rubber friction pad, the second rubber friction pad, and the third rubber friction pad are on the same plane.

[0009] Preferably, the set screw threaded connection passes through the concave frame and extends to the top of the convex rod, and the concave frame and the convex rod are distributed parallel to the sliding frame.

[0010] Preferably, the end of the reinforcing rod away from the concave frame is fixedly installed on the opposite side of the sliding sleeve. The sliding frame, slider, support rod, concave frame, convex rod and ring block are evenly distributed in a circle on the outside of the hydraulic telescopic rod two. The hydraulic telescopic rod one, hydraulic telescopic rod two, Rockwell hardness test indenter, through hole and ring block are concentric circles.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using the device, the photovoltaic material to be tested is placed on the top of the workbench, and then the hydraulic telescopic rod is extended to drive the slide plate down, thereby pushing the slide plate and slide frame structure down, so that the first rubber friction pad, the second rubber friction pad and the third rubber friction pad at the bottom of the concave frame and the convex rod come into contact with the top of the material plate. Then the hydraulic telescopic rod extends and passes through the ring block to bring the Rockwell hardness testing indenter into contact with the top of the photovoltaic material plate for testing. When the size needs to be adjusted, the position of the convex rod inside the concave frame is adjusted by telescoping, thereby driving the ring block to change position, so that the concave frame, the convex rod and the ring block are away from the testing position of the Rockwell hardness testing indenter, thereby realizing the adjustment. By tightening the set screw, a fixing effect is applied to the convex rod, which facilitates the adjustment and increases the convenience of use.

[0012] This invention supports the concave frame, convex rod, and ring block by transmitting the force through the same plane of the support rod and reinforcing rod. This ensures that the downward pressing force of the sliding plate is evenly transmitted through the support rod, reinforcing rod, and sliding frame, maintaining the relative stability of the structure. In addition, the uniform circumferential distribution increases the relative stability of the structure when pressing the material plate, maintains the torque stability, and facilitates stable pressing.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a hardness testing device for photovoltaic production with a pressing function, including a workbench 1, four pillars 2 fixedly installed on the top of the workbench 1, a top plate 5 fixedly installed on the top of the four pillars 2, a hydraulic telescopic rod 6 fixedly installed on the bottom of the top plate 5, a bracket 7 fixedly installed at the output end of the hydraulic telescopic rod 6, a slide plate 4 fixedly installed at the bottom end of the bracket 7, and sliding sleeves 9 fixedly fitted on the inner sides of the four corners of the slide plate 4. A second hydraulic telescopic rod 8 is fixedly installed on the bottom surface of the top of the bracket 7. A through hole 11 is opened in the middle of the slide plate 4, and the second hydraulic telescopic rod 8 extends to the bottom of the slide plate 4 through the through hole 11. A Rockwell hardness testing indenter 10 is fixedly installed at the output end of the second hydraulic telescopic rod 8. A sliding frame 3 is connected to the sliding frame 3. Four concave frames 16 are fixedly installed at the diagonal inside the sliding frame 3. A convex rod 17 is slidably connected to the inner side of the opposite ends of the four concave frames 16. A ring block 20 is fixedly installed at the opposite end of the convex rod 17. A third rubber friction pad 21 is fixedly installed at the bottom of the ring block 20. A support rod 14 is fixedly installed at the top of the ring block 20. A slider 13 is fixedly installed at the top of the support rod 14. A sliding frame 12 is slidably installed on the outer side of the slider 13. A second rubber friction pad 19 is fixedly installed at the bottom of the concave frame 16. A first rubber friction pad 18 is fixedly installed at the bottom of the convex rod 17. A set screw 22 is threaded through the top of the four concave frames 16 at the end away from the sliding frame 3. A reinforcing rod 15 is fixedly installed at the top of each of the four concave frames 16.

[0020] The working principle of the above technical solution is as follows: In use, the photovoltaic material to be tested is placed on the top of the workbench 1. Then, the hydraulic telescopic rod 6 is extended, driving the slide plate 4 to move down, thereby pushing the slide plate 4 and the slide frame 3 structure down, so that the first rubber friction pad 18, the second rubber friction pad 19 and the third rubber friction pad 21 at the bottom of the concave frame 16 and the convex rod 17 contact the top of the material plate. Then, the hydraulic telescopic rod 8 extends and passes through the ring block 20 to contact the Rockwell hardness testing indenter 10 with the top of the photovoltaic material plate for testing. When the size needs to be adjusted, the position of the convex rod 17 inside the concave frame 16 is adjusted by telescopic adjustment, thereby driving the ring block 20 to change position, so that the concave frame 16, the convex rod 17 and the ring block 20 are away from the testing position of the Rockwell hardness testing indenter 10, thereby realizing the adjustment. By tightening the set screw 22, a fixing effect is applied to the convex rod 17, which facilitates the use and adjustment and increases the convenience of use.

[0021] In another implementation scheme, such as Figures 1-4 As shown, the sliding sleeve 9 is movably fitted onto the outside of the support column 2.

[0022] The sliding sleeve 9 limits the sliding plate 4, which facilitates the relative stability of the structure and the limiting of sliding.

[0023] In another implementation scheme, such as Figures 1-4 As shown, the sliding frame 12 is fixedly installed on the bottom of the slide plate 4.

[0024] The sliding frame 12 provides a limiting sliding position for the slider 13 and transmits the downward pressure of the slide plate 4 through the slider 13 and the support rod 14, thus keeping the structure relatively stable.

[0025] In another implementation scheme, such as Figures 1-4 As shown, the bottoms of the concave frame 16 and the convex rod 17 are on the same plane, and the bottoms of the first rubber friction pad 18, the second rubber friction pad 19, and the third rubber friction pad 21 are on the same plane.

[0026] The concave frame 16 and the convex rod 17, through a pull-out structure with concave-convex interlocking and limiting, keep their bottoms on the same plane and provide installation positions for the horizontal surfaces of the first rubber friction pad 18 and the second rubber friction pad 19. This ensures that the structure remains horizontal during the pressing process, increases the stability of the pressing, and thus maintains the stability of the structural torque.

[0027] In another implementation scheme, such as Figures 1-4 As shown, the set screw 22 is threaded through the concave frame 16 and extends to the top of the convex rod 17. The concave frame 16 and the convex rod 17 are distributed in parallel with the sliding frame 12.

[0028] The force transmitted through the same plane of the support rod 14 and the reinforcing rod 15 supports the concave frame 16, the convex rod 17 and the ring block 20, so that the downward pressing force of the slide plate 4 is evenly transmitted through the support rod 14, the reinforcing rod 15 and the slide frame 3, maintaining the relative stability of the structure. In conjunction with the even distribution around the circumference, the relative stability of the structure is increased when pressing the material plate, maintaining the torque stability and facilitating stable pressing.

[0029] In another implementation scheme, such as Figures 1-4 As shown, the end of the reinforcing rod 15 away from the concave frame 16 is fixedly installed on the opposite side of the sliding sleeve 9. The sliding frame 12, slider 13, support rod 14, concave frame 16, convex rod 17 and ring block 20 are evenly distributed in a circle on the outside of the hydraulic telescopic rod 28. The hydraulic telescopic rod 16, hydraulic telescopic rod 28, Rockwell hardness test indenter 10, through hole 11 and ring block 20 are concentric circles.

[0030] The reinforcing rod 15 provides a stable force transmission for the concave frame 16, which helps to maintain the stability of the structural force. The sliding frame 12, slider 13, support rod 14, concave frame 16, convex rod 17 and ring block 20 are symmetrically distributed diagonally around the circumference, which helps to stabilize the clamping position when pressing the material plate, thus stabilizing the force and maintaining the stability of the structural force, indirectly ensuring the relative stability of the structure during hardness testing.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
