Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic glass strength detection, and in particular to a large-size TOPCon photovoltaic glass strength detection device. Background Art

[0002] The large-scale TOPCon photovoltaic glass strength testing equipment is an instrument specifically designed to evaluate and test the mechanical properties and damage resistance of large-scale TOPCon photovoltaic glass materials. This strength testing equipment can be likened to a "strength tester for photovoltaic glass." It evaluates the performance of glass under stress, just like testing an athlete's muscle strength, ensuring that the glass remains "rock-solid" in the face of various challenges.

[0003] Currently, in the strength testing of large-size photovoltaic glass, due to the large size of large-size photovoltaic glass, the testers cannot easily adjust the test angle of the photovoltaic glass during pressure testing. Testing the force at other angles of the photovoltaic glass may easily cause the photovoltaic glass testing to be incomplete, resulting in errors in the photovoltaic glass strength testing. Summary of the Invention

[0004] The purpose of the present invention is to provide a large-size TOPCon photovoltaic glass strength testing equipment, in which the first half gear and the second half gear of the fixed component are engaged with each other to drive the second half gear to rotate, so that the second half gear drives the fixed platform to flip over, thereby preventing the test personnel from being unable to easily adjust the test angle of the photovoltaic glass due to the large size and perform strength testing on other angles of the photovoltaic glass, resulting in errors in the strength testing.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a large-scale TOPCon photovoltaic glass strength testing equipment, including a testing machine, a fixing assembly installed on the testing machine, the fixing assembly including a cylinder fixedly installed on the testing machine, a first half gear installed on the output end of the cylinder, a second half gear engaged with one side of the first half gear, a fixed platform fixedly installed on one end of the second half gear, one side of the fixed platform is connected to an external suction machine through a pipeline, a plurality of groups of support pads are provided on the testing machine, the support pads are arranged between the fixed platform and the testing machine, a group of suction cups are installed on the fixed platform, A piston plate is slidably installed inside the fixed platform, and a pull rod is fixedly connected to one side of the piston plate. One end of the pull rod is installed on the testing machine, and one end of the pull rod extends through the fixed platform for installation, and one end of the pull rod is rotatably connected to the telescopic rod, and one end of the telescopic rod is rotatably connected to the mounting seat, and one side of the mounting seat is fixedly installed on the testing machine, elastic rods are fixedly connected to both sides of the first half gear, and a first oblique block is fixedly connected to one side of the elastic rod, and both sides of the first half gear are fixedly connected to a first connecting frame, and one end of two groups of the first connecting frames is fixedly connected to one end of the elastic rod, and a first spring is fixedly connected inside the elastic rod.

[0006] The testing machine is equipped with a protective assembly, which includes a protective frame. Two groups of magnetically connected protective doors are installed on one side of the protective frame. One side of the two groups of protective doors is slidably connected to a second inclined block. One side of the second inclined block is fixedly connected to the pressure rod of the testing machine. The lower ends of the two groups of protective frames are equipped with extrusion blocks. The lower ends of the protective doors are provided with a second inclined slot. The first inclined block is slidably connected to the second inclined slot.

[0007] Preferably, the upper end of each of the protective doors is provided with a first inclined groove, the second inclined block is slidably connected to the first inclined groove, and a magnet is provided on one side of the second inclined block.

[0008] Preferably, one side of the second oblique block is also fixedly connected to an elastic rod, one end of the elastic rod is fixedly connected to a second connecting frame, and one side of the second connecting frame is fixedly connected to the pressure rod of the testing machine.

[0009] Preferably, a groove is provided at the lower end of the protective door, a second spring is connected inside the groove, one end of the second spring is fixedly connected to a connecting rod, and one side of the connecting rod is also fixedly connected to an extrusion block.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In the present invention, the first half gear moves to the second half gear and meshes with the second half gear, driving the second half gear to rotate, so that the second half gear drives the fixed platform to flip, thereby facilitating construction personnel to adjust the test angle of the photovoltaic glass at multiple angles. Due to the need to prevent large-size photovoltaic glass from being too large when testing on a testing machine, the test personnel cannot easily adjust the test angle of the photovoltaic glass and perform strength tests on other angles of the photovoltaic glass, resulting in errors in the strength test.

[0012] 2. When the present invention rises on one side of the fixed platform, the pull rod pulls the piston plate to move inside the fixed platform. If the pull rod pulls the piston plate to move inside the fixed platform, it means that there is excess gas inside the fixed platform and the suction cup. Therefore, the pull rod pulls the piston plate to move inside the fixed platform, evacuating the residual gas inside the fixed platform, and assisting the suction cup to fix the photovoltaic glass panel, thereby preventing the fixed platform from causing the photovoltaic glass to flip.

[0013] 3. In the present invention, the first spring drives the elastic rod to compress, so that the second inclined block is separated from the first inclined groove. The two sets of protective doors are not subjected to the pulling force of the second inclined block. The two sets of protective doors are attracted to each other through the magnets on one side and slide together on one side of the protective frame, so that the testing machine is in a sealed state, avoiding the photovoltaic glass from shattering during the inspection process, and the photovoltaic glass from splashing randomly, which may cause harm to the inspectors.

[0014] 4. In the present invention, when the cylinder drives the first half gear to move forward, both sides of the first half gear drive the elastic rod to move forward through the first connecting frame, and the elastic rod drives the first inclined block to move forward to the inside of the second inclined slot. The first inclined block applies pressure to the protective door through the second inclined slot. If the protective door is squeezed and separated by the first inclined block, it means that the magnet on one side of the protective door has caused wear and aging when the protective door is used for a long time, and the magnetic force of the magnet is weakened. The inspector stops testing and replaces the magnet to prevent the protective door from sliding open and photovoltaic glass fragments from flying due to excessive internal testing pressure during the testing process. In this way, the inspector is not affected by the vibration of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See Figures 1 to 6 As shown, the present invention provides a large-size TOPCon photovoltaic glass strength testing device, including a testing machine 1, a fixing component 2 is installed on the testing machine 1, the fixing component 2 includes a cylinder 201 fixedly installed on the testing machine 1, a first half gear 203 is installed at the output end of the cylinder 201, a second half gear 204 is meshed with one side of the first half gear 203, a fixing platform 205 is fixedly installed at one end of the second half gear 204, and a suction machine is externally connected to one side of the fixing platform 205 through a pipeline. A plurality of support pads are provided on the testing machine 1, and the support pads are arranged between the fixing platform 205 and the testing machine 1. A group of suction cups 206 are installed on the fixing platform 205, and a piston plate is slidably installed inside the fixing platform 205. 207, one side of the piston plate 207 is fixedly connected to a pull rod 208, one end of the pull rod 208 is installed on the testing machine 1, one end of the pull rod 208 extends through the fixed platform 205 for installation, and one end of the pull rod 208 is rotatably connected to a telescopic rod 213, one end of the telescopic rod 213 is rotatably connected to a mounting seat, one side of the mounting seat is fixedly installed on the testing machine 1, both sides of the first half gear 203 are fixedly connected to elastic rods 210, one side of the elastic rod 210 is fixedly connected to a first inclined block 211, both sides of the first half gear 203 are fixedly connected to first connecting frames 209, one end of two sets of first connecting frames 209 is fixedly connected to one end of the elastic rod 210, and a first spring 212 is fixedly connected inside the elastic rod 210;

[0026] The inspector places the photovoltaic glass on the fixing platform 205 of the fixing assembly 2, and the construction personnel starts the external suction machine to empty the air inside the suction cup 206 on the fixing platform 205, thereby fixing the photovoltaic glass, and then starts the cylinder 201. The cylinder 201 drives the first half gear 203 to move forward, and the first half gear 203 moves to the second half gear 204, meshing with the second half gear 204, driving the second half gear 204 to rotate, so that the second half gear 204 drives the fixing platform 205 to flip, thereby facilitating the construction personnel to adjust the test angle of the photovoltaic glass at multiple angles. Due to the need to prevent the large-sized photovoltaic glass from being too large when testing on the testing machine 1, the inspector cannot easily adjust the test angle of the photovoltaic glass and perform strength tests on other angles of the photovoltaic glass, resulting in errors in the strength test;

[0027] At the same time as the second half gear 204 drives the fixed platform 205 to flip, since one end of the pull rod 208 is fixed to the testing machine 1 through the telescopic rod 213, when one side of the fixed platform 205 rises, the pull rod 208 pulls the piston plate 207 to move inside the fixed platform 205. If the pull rod 208 pulls the piston plate 207 to move inside the fixed platform 205, it means that there is still excess gas inside the fixed platform 205 and the suction cup 206, so the pull rod 208 pulls the piston plate 207 to move inside the fixed platform 205, and the fixed platform 205 is evacuated. The residual gas inside assists the suction cup 206 in fixing the photovoltaic glass panel, preventing the fixing platform 205 from driving the photovoltaic glass to flip while the external suction machine fails to evacuate the air inside the suction cup 206, causing the photovoltaic glass to fall during movement and damage the photovoltaic glass. If there is no excess gas inside the fixing platform 205 and the suction cup 206, the pull rod 208 will not be able to pull the piston plate 207 to move inside the fixing platform 205, causing the telescopic rod 213 to extend and retract, thereby not affecting the fixing platform 205 from driving the photovoltaic glass to flip;

[0028] See Figures 7 and 8 As shown, the testing machine 1 is equipped with a protective assembly 3, which includes a protective frame 301. Two sets of magnetically connected protective doors 302 are installed on one side of the protective frame 301. One side of each set of protective doors 302 is slidably connected to a second inclined block 303. One side of the second inclined block 303 is fixedly connected to the pressure rod of the testing machine 1. The lower end of each set of protective frames 301 is equipped with an extrusion block 306. The lower end of the protective door 302 is provided with a second inclined slot, and the first inclined block 211 is slidably connected to the second inclined slot.

[0029] After the inspector has adjusted the inspection angle of the photovoltaic glass through the fixing assembly 2, the tester 1 is started, and the pressure rod above the tester 1 is pressed down. The pressure rod drives the second inclined blocks 303 on both sides to move downward through the elastic rod 210. The two groups of second inclined blocks 303 move downward and slide through the inclined surface and the inclined surface of the first inclined groove, and rebound a force in the opposite direction, so that the first spring 212 inside the elastic rod 210 is compressed, and the first spring 212 drives the elastic rod 210 to compress, so that the second inclined blocks 303 are separated from the first inclined groove, and the two groups of protective doors 302 are not subjected to the pulling force of the second inclined blocks 303. The two groups of protective doors 302 are attracted to each other by the magnet 307 on one side, and slide together on one side of the protective frame 301, so that the tester 1 is in a sealed state, so as to avoid the photovoltaic glass from breaking during the inspection process and the photovoltaic glass from splashing randomly, causing injuries to the inspectors;

[0030] The two sets of protective doors 302 are attracted to each other by the magnet 307 on one side. When they slide and merge together on one side of the protective frame 301, if the photovoltaic glass is placed flat for inspection, the protective door 302 will drive the squeezing block 306 through the connecting rod to move to the gap where the suction cup 206 is fixedly connected to the photovoltaic glass. If the squeezing block 306 squeezes and opens the connection between the suction cup 206 and the photovoltaic glass, it means that the external suction machine has not evacuated the air inside the suction cup 206 through the fixing platform 205. The inspector restarts the external suction machine to evacuate the air inside the suction cup 206 again, so that the photovoltaic glass is fixed more firmly without affecting the inspection efficiency.

[0031] When the cylinder 201 drives the first half gear 203 to move forward, both sides of the first half gear 203 drive the elastic rod 210 to move forward through the first connecting frame 209, and the elastic rod 210 drives the first inclined block 211 to move forward to the inside of the second inclined slot. The first inclined block 211 applies pressure to the protective door 302 through the second inclined slot. If the protective door 302 is squeezed and separated by the first inclined block 211, it means that the magnet 307 on one side of the protective door 302 has caused wear and aging when the protective door 302 is used for a long time, and the magnetic force of the magnet 307 is weakened. The inspector stops the inspection and replaces the magnet 307 to prevent the protective door 302 from sliding open and photovoltaic glass fragments from flying due to excessive internal inspection pressure during the inspection process. It affects the normal work of the inspector.

[0032] First, the cylinder 201 drives the first half gear 203 to engage with the second half gear 204, thereby driving the angle adjustment of the photovoltaic glass to prevent the test personnel from being inconvenient to adjust the test angle of the photovoltaic glass due to excessive size, resulting in errors in strength detection. Then the pressure rod of the testing machine 1 drives the two sets of protective doors 302 of the protective assembly 3 to merge, avoiding the photovoltaic glass from splashing and preventing the inspectors from being injured. While the cylinder 201 in the fixed assembly 2 drives the first half gear 203, it also drives the first bevel 211 to detect the firmness of the merging of the protective doors 302 in the protective assembly 3.

[0033] In an optional embodiment, a first inclined groove is provided at the upper end of the protective door 302, and two groups of second inclined blocks 303 move downward through the inclined surface and slide with the inclined surface of the first inclined groove. The second inclined blocks 303 are slidably connected to the first inclined groove, and a magnet 307 is provided on one side of the second inclined block 303. The two groups of protective doors 302 are attracted to each other through the magnet 307 on one side.

[0034] In an optional embodiment, one side of the second inclined block 303 is also fixedly connected to the elastic rod 210, one end of the elastic rod 210 is fixedly connected to the second connecting frame 304, one side of the second connecting frame 304 is fixedly connected to the pressure rod of the testing machine 1, and the second connecting frame 304 is used to fix and support the elastic rod 210 for operation.

[0035] In an optional embodiment, a groove is provided at the lower end of the protective door 302, and a second spring 305 is connected inside the groove. One end of the second spring 305 is fixedly connected to a connecting rod, and one side of the connecting rod is also fixedly connected to an extrusion block 306. If the extrusion block 306 squeezes open the connection between the suction cup 206 and the photovoltaic glass, the suction cup 206 and the photovoltaic glass will transmit pressure through the extrusion block 306, causing the second spring 305 to contract, so that the second spring 305 drives the extrusion block 306 to move backward, indicating that the photovoltaic glass is firmly fixed.

[0036] Working principle: the inspection personnel place the photovoltaic glass on the fixing platform 205 of the fixing component 2, and the construction personnel start the external suction machine to empty the air inside the suction cup 206 on the fixing platform 205, thereby fixing the photovoltaic glass, and then start the cylinder 201, and the cylinder 201 drives the first half gear 203 to move forward, and the first half gear 203 moves to the second half gear 204, meshing with the second half gear 204, driving the second half gear 204 to rotate, so that the second half gear 204 drives the fixing platform 205 to flip, so as to facilitate the construction personnel to adjust the test angle of the photovoltaic glass at multiple angles. Due to the reason of preventing the large-sized photovoltaic glass from being too large when testing on the testing machine 1, the inspection personnel cannot easily adjust the test angle of the photovoltaic glass and perform strength tests on other angles of the photovoltaic glass, resulting in errors in the strength test;

[0037] At the same time as the second half gear 204 drives the fixed platform 205 to flip, since one end of the pull rod 208 is fixed to the testing machine 1 through the telescopic rod 213, when one side of the fixed platform 205 rises, the pull rod 208 pulls the piston plate 207 to move inside the fixed platform 205. If the pull rod 208 pulls the piston plate 207 to move inside the fixed platform 205, it means that there is still excess gas inside the fixed platform 205 and the suction cup 206, so the pull rod 208 pulls the piston plate 207 to move inside the fixed platform 205, and the fixed platform 205 is evacuated. The residual gas inside assists the suction cup 206 in fixing the photovoltaic glass panel, preventing the fixing platform 205 from driving the photovoltaic glass to flip while the external suction machine fails to evacuate the air inside the suction cup 206, causing the photovoltaic glass to fall during movement and damage the photovoltaic glass. If there is no excess gas inside the fixing platform 205 and the suction cup 206, the pull rod 208 will not be able to pull the piston plate 207 to move inside the fixing platform 205, causing the telescopic rod 213 to extend and retract, thereby not affecting the fixing platform 205 from driving the photovoltaic glass to flip;

[0038] After the inspector has adjusted the inspection angle of the photovoltaic glass through the fixing assembly 2, the tester 1 is started, and the pressure rod above the tester 1 is pressed down. The pressure rod drives the second inclined blocks 303 on both sides to move downward through the elastic rod 210. The two groups of second inclined blocks 303 move downward and slide through the inclined surface and the inclined surface of the first inclined groove, and rebound a force in the opposite direction, so that the first spring 212 inside the elastic rod 210 is compressed, and the first spring 212 drives the elastic rod 210 to compress, so that the second inclined blocks 303 are separated from the first inclined groove, and the two groups of protective doors 302 are not subjected to the pulling force of the second inclined blocks 303. The two groups of protective doors 302 are attracted to each other by the magnet 307 on one side, and slide together on one side of the protective frame 301, so that the tester 1 is in a sealed state, so as to avoid the photovoltaic glass from breaking during the inspection process and the photovoltaic glass from splashing randomly, causing injuries to the inspectors;

[0039] The two sets of protective doors 302 are attracted to each other by the magnet 307 on one side. When they slide and merge together on one side of the protective frame 301, if the photovoltaic glass is placed flat for inspection, the protective door 302 will drive the squeezing block 306 through the connecting rod to move to the gap where the suction cup 206 is fixedly connected to the photovoltaic glass. If the squeezing block 306 squeezes and opens the connection between the suction cup 206 and the photovoltaic glass, it means that the external suction machine has not evacuated the air inside the suction cup 206 through the fixing platform 205. The inspector restarts the external suction machine to evacuate the air inside the suction cup 206 again, so that the photovoltaic glass is fixed more firmly without affecting the inspection efficiency.

[0040] When the cylinder 201 drives the first half gear 203 to move forward, both sides of the first half gear 203 drive the elastic rod 210 to move forward through the first connecting frame 209, and the elastic rod 210 drives the first inclined block 211 to move forward to the inside of the second inclined slot. The first inclined block 211 applies pressure to the protective door 302 through the second inclined slot. If the protective door 302 is squeezed and separated by the first inclined block 211, it means that the magnet 307 on one side of the protective door 302 has caused wear and aging when the protective door 302 is used for a long time, and the magnetic force of the magnet 307 is weakened. The inspector stops the inspection and replaces the magnet 307 to prevent the protective door 302 from sliding open and photovoltaic glass fragments from flying due to excessive internal inspection pressure during the inspection process. It affects the normal work of the inspector.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
