Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic panel production, in particular to a detection device for solar photovoltaic panel production. Background Art

[0002] Solar photovoltaic panels are devices that use the semiconductor photovoltaic effect to convert solar radiation into electrical energy. They are based on the fact that photons cause semiconductors to generate electron-hole pairs, which form a potential difference under the action of a built-in electric field to generate electricity. The principles of different photovoltaic materials are different. The structure includes components such as cells, packaging materials, backplanes and frames. The cells are combined in a specific connection method. The performance parameters include photoelectric conversion efficiency, open circuit voltage, short circuit current and fill factor. They are widely used. In the power system, large-scale power stations can be built for grid-connected power generation. Off-grid systems can provide power for remote areas. They are also used in consumer electronic products. The development trend is that efficiency continues to increase, costs continue to decrease, and they move towards integration and multi-functionality, such as the emergence of photovoltaic building integrated products.

[0003] However, most of the various types of equipment currently available on the market for solar photovoltaic panel testing have certain limitations. They often only have one test function and cannot perform multiple test operations at the same time. In other words, when testing solar photovoltaic panels, staff can only use the corresponding equipment in turn according to different test items to carry out the testing work. In this way, the entire testing process is quite complicated and the testing cycle is relatively long, which will undoubtedly seriously hinder the listing process of solar photovoltaic panels and greatly increase the time span from production completion to market launch.

[0034] To sum up, when the rod wheel ring 22 cooperates with the pressure strip 221 to squeeze the liquid capsule 211 below, the liquid inside the liquid capsule 211 enters the circulating liquid channel 1111 on the right through the liquid supply pipeline 212, and supports the first spring piston 118 upward, so that the first spring piston 118 pushes the electrical measuring component 1181 upward to contact the structure of the solar panel 3, so as to detect whether there is leakage in the solar panel 3, accurately evaluate the insulation performance of the solar panel 3, and timely discover the leakage risks that may exist in the solar panel 3 after production, thereby improving the quality and safety of the solar panel 3.

At this time, the temperature control pipe rack 122 is connected to the test structure 1 through the pipeline. The hot and cold fluid supply equipment arranged at the part is connected, and then the actual sunlight exposure and the installation angle of the actual solar panel 3 can be referred to to control the adjustment motor 124 to rotate and adjust the angle of the solar panel 3, and then the solar panel 3 can be tested. During the test, the driving motor 112 will drive the transmission wheel 1121 to rotate, and the rotating transmission wheel 1121 will rotate the rod wheel ring 22, so that the rod wheel ring 22 rotates at a uniform speed along the slide groove of the ring frame 21, and the rotation speed can refer to the sun rise and fall time parameters of the installation site, and then the rod wheel ring 22 will drive the sun simulation lamp frame 23 to do a circular motion around the solar panel 3. During the movement, first, under the drive of the driving motor 112, the rod wheel ring 22 will synchronously rotate the driven wheel 113 The driven wheel disc 113 will coaxially drive the driving gear 114 to rotate, and then the driving gear 114 will mesh with the inner gear ring 115 to make the inner gear ring 115 rotate inside the test machine body 11, and then the rotating inner gear ring 115 will drive the reciprocating screw rod 116 connected thereto to rotate, and the rotating reciprocating screw rod 116 will cooperate with the wire groove on the surface to drive the transmission seat 1161 to slide back and forth in a straight line inside the test machine body 11, and during the sliding process, it will drive the push rod 1162 to push the on and off button of the power switch 1163 to realize the on and off control of the dimming switch 1174. When the rod wheel ring 22 drives the solar simulation lamp holder 23 to move to a position relatively flush with the solar panel 3, at this time, the push rod 1162 will push the power switch 1163. Switch 1163 is turned on to energize the dimmer switch 1174. At the same time, as the drive motor 112 continues to drive the rod wheel ring 22 to rotate, the rotating reciprocating screw 116 will drive the drive rod 117 to rotate, and then the drive rod 117 will drive the push plate 1171 to push the baffle 1172 to drive the knob switch of the dimmer switch 1174 to rotate, and at the same time, the button reset torsion spring 1175 is twisted and contracted. As the knob switch rotates, the current to the sun simulation lamp holder 23 will be gradually controlled to increase, and then the sun simulation lamp holder 23 will gradually increase the intensity of light when it rotates around the solar panel 3. The intensity and angle of light received by the solar panel 3 will change synchronously with the actual situation. At the same time, as the knob of the dimmer switch 1174 is rotated,It will control the gradual opening of the electric control valve at the output interface of the temperature control tube rack 122, and then the hot fluid or cold fluid entering the temperature control tube rack 122 will gradually increase, and then the temperature control tube rack 122 will gradually adjust the temperature of the environment in which the solar panel 3 is located to increase or decrease the temperature according to the weather conditions and the hot and cold fluid supply end. At this time, the detection component inside the test structure 1 will detect the electrical performance parameters of the solar panel 3 in real time, and feed them back to the control end for sorting and display, and then, driven by the drive motor 112, the rod wheel ring 22 will drive the pressure strip 221 to move along the slide groove of the ring frame 21 to the position of the upper liquid capsule 211, and squeeze the safety liquid stored in the upper liquid capsule 211 into the upper liquid supply pipeline 212, and along the liquid supply pipeline. 212 and the pipeline enter the circulating fluid channel 1111 on the right, and hydraulically support the second spring piston 119 to slide upward along the inner wall of the circulating fluid channel 1111. The upward moving second spring piston 119 will drive the distribution rack 1191 to move upward, and in the process of moving upward, support the spring top rod 1192, and the upper end of the spring top rod 1192 presses on the bottom surface of the solar panel 3, applying mechanical pressure to the bottom of the solar panel 3, and then as the pressure strip 221 squeezes the liquid capsule 211 The distance gradually increases, the liquid entering the left circulating fluid channel 1111 will gradually increase, and then the second spring piston 119 will further rise, and push the spring top rod 1192 to further support the solar panel 3, increasing the pressure on the top support of the solar panel 3. At the same time, the staff can understand the working status of the solar panel 3 after the pressure is applied through the feedback of the test structure 1 on the solar panel 3. When the solar simulation lamp holder 23 is driven by the driving motor 112 and rotates to the top, the driving rod 117 will drive the knob of the dimmer switch 1174 to rotate to the maximum power position, and as the solar simulation lamp holder 23 continues to rotate, the driving rod 117 will drive the knob of the dimmer switch 1174 to gradually change from the maximum power to the low power, until the knob of the dimmer switch 1174 rotates 180 degrees and is closed, and the light intensity of the solar simulation lamp holder 23 and the electric control valve at the output interface of the temperature control tube holder 122 will gradually decrease and close, and the reciprocating screw rod 116 will cooperate with the driven wheel disc on the rod wheel ring 22 at this time. 113, the driving gear 114 and the inner gear ring 115 are indirectly driven to drive the transmission seat 1161 and the top rod 1162 to press the button of the power switch 1163, so that the dimmer switch 1174 is powered off. At the same time, as the driving rod 117 cooperates with the push plate 1171 to rotate and apply pressure to the baffle 1172, since the knob of the dimmer switch 1174 is rotated to the maximum angle, the push plate 1171 will break through the blocking of the baffle 1172, so that the baffle 1172 twists the torsion spring 1173 and then rotates, and then the driving rod 117 will drive the push plate 1171 to break away from the blocking restriction of the baffle 1172 and continue to rotate to the initial position, and then the knob of the dimmer switch 1174 will rotate and reset under the action of the twisted button reset torsion spring 1175.As the driving motor 112 cooperates with the transmission wheel 1121 to continue to drive the rod wheel ring 22, the rod wheel ring 22 will cooperate with the pressure strip 221 to squeeze the liquid capsule 211 below, so that the liquid inside the liquid capsule 211 enters the right circulating liquid channel 1111 through the liquid supply pipeline 212, and the first spring piston 118 is supported upward, so that the first spring piston 118 drives the electrical measurement component 1181 to move up and contact the structure of the solar panel 3, so as to detect whether the solar panel 3 has leakage, until the driving motor 112 cooperates with the transmission wheel 1121 to drive the rod wheel ring 22 to drive the sun simulation lamp holder 23 to move to the initial position, and then return to the next detection cycle until the detection is completed.

[0036] It should be noted that the sides where the liquid capsule 211 and the pressure strip 221 meet are rounded; the first spring piston 118 is a spring rod structure that can automatically retract and reset.
