[0054] like Figures 1 to 12As shown, a specific embodiment of the present invention provides a photovoltaic panel hidden crack detection system including: a detection module for detecting hidden cracks on a panel, a cloud for receiving detection results of the panel by the detection module; an identification module for identifying the location of the hidden cracks on the panel;

[0055] The detection module includes:

[0056] A guide assembly 301, used to transport and lift the solar panel;

[0057] The clamping assembly 401 is used to cooperate with the guiding assembly 301 to position the solar panel;

[0058] A camera unit is used to analyze the solar panels and detect the location of hidden cracks;

[0059] A communication unit, used for communicating with the outside world;

[0060] The cloud includes:

[0061] A storage unit, used for receiving and storing battery panel information;

[0062] An instruction sending unit, used for sending instructions to the outside world;

[0063] The identification module includes:

[0064] Identification unit, used to read the solar panel information;

[0065] A display unit, used for displaying the hidden crack position of the solar panel according to the solar panel information;

[0066] A motion unit, used for changing the position of the display unit so as to make it face the position of the hidden crack of the solar panel;

[0067] The guide assembly 301 cooperates with the clamping assembly 401 to position and lift the solar panel. During the lifting process, the contact position between the guide assembly 301 and the bottom of the solar panel changes continuously. The camera unit performs multi-position camera analysis on the bottom of the solar panel and combines the multiple camera analysis results into the detection result of the bottom of the solar panel. After the lifting is completed, the clamping assembly 401 is withdrawn, and the camera unit performs camera analysis on the top and surrounding areas of the solar panel and sends the detection results to the cloud.

[0068] During use, the battery panel is conveyed to the detection module by a conveyor belt or other tools. The guide component 301 lifts and guides the battery panel conveyed by the conveyor belt and conveys it between the clamping components 401. The battery panel is located between two sets of opposite guide components 301 and two sets of opposite clamping components 401. The guide component 301 cooperates with the clamping component 401 to position the battery panel. The detection module reads the battery nameplate information. Then, the guide component 301 cooperates with the clamping component 401 to lift the battery panel. During the lifting process, the contact position between the guide component 301 and the bottom of the battery panel changes. The camera unit passes The unobstructed part of the bottom plate of the battery panel is photographed in batches and spliced ​​into the detection result of the bottom of the battery panel. After the lifting is completed, the clamping assembly 401 is withdrawn, and the camera unit performs camera detection on the surroundings and top of the battery panel, and sends the detection results to the cloud. The cloud storage unit stores the hidden crack information of the battery panel. After that, after the identification module reads the nameplate information of the battery panel, the cloud retrieves the hidden crack information of the battery panel from the storage unit and generates a coordinate instruction, which is sent to the identification module by the instruction sending unit. The motion unit drives the display unit to move to the vicinity of the specified coordinates, and the display unit displays it on the battery panel with a photoelectric signal. During the entire detection process, the battery panel is always in the same state, and there is no need to flip it or move it too much, which can minimize the hidden dangers of damaging the stability of the battery panel structure. At the same time, it can store the hidden crack information of the battery panel to avoid the risk of the identification mark being erased during transportation.

[0069] In some optional specific embodiments, such as Figure 2-12 As shown, the detection module includes a base 101, two sets of side panels 102 are installed on the side of the base 101, a driving telescopic rod 403 is connected between the clamping assembly 401 and the side panel 102, and a lifting seat 103 that can be lifted and lowered is also installed on the base 101, and a driving motor 320 is installed on the lifting seat 103. The driving motor 320 is connected to a driving gear 319, and the driving gear 319 is meshed and connected to a transmission gear 318. The transmission gear 318 is connected to a threaded cylinder 316, and both ends of the threaded cylinder 316 are respectively connected to bearing seats 317 through bearings. 317 is fixedly connected to the lifting seat 103, and two ends of the threaded cylinder 316 are respectively threadedly connected with two groups of threaded rods 312, and the threaded cylinder 316 rotates to drive the two groups of threaded rods 312 to move toward or away from each other, and the ends of the threaded rods 312 are connected with racks 311, and the racks 311 are dynamically connected to the telescopic frame 309, and the telescopic frame 309 is movably connected to the support plate 201, and a support plate 313 is fixedly connected between the support plate 201 and the base 101, and a telescopic groove is opened on the support plate 201 for the telescopic frame 309 to move therein, and the telescopic frame 309 is connected to the guide assembly 301.

[0070] When positioning the circuit board, the driving motor 320 is started, and the driving motor 320 drives the driving gear 319 to rotate, and then the meshing transmission gear 318 rotates, so that the threaded cylinder 316 rotates, and the rotation of the threaded cylinder 316 drives the threaded rod 312 to retract, thereby pulling the telescopic frame 309 to retract into the telescopic groove of the support plate 201, so that the battery panel is clamped by the two groups of guide components 301, and then the driving telescopic rod 403 drives the two groups of clamping components 401 to move, clamping the battery panel from the other two ends until it is centered, and the positioning is completed.

[0071] In some optional specific embodiments, such as Figure 2-12 As shown, the guide assembly 301 includes an installation roller seat 302, in which a roller seat groove is opened, in which a lifting roller seat 303 is adapted to be installed, and an air cavity 3022 is formed between the lifting roller seat 303 and the bottom of the roller seat groove. The air cavity 3022 is sealed and installed with an air pressure switch, and the air cavity 3022 is connected to an external air circuit, and a reset spring is connected to the bottom of the lifting roller seat 303 and the roller seat groove, so that the lifting roller seat 303 is stable at a preset height, and a transmission roller 304 is installed in the lifting roller seat 303, and a rotating shaft 3043 is connected between the transmission roller 304 and the lifting roller seat 303, and the rotating shaft 3043 is connected to a transmission motor 3041, and the air pressure switch is used to start the driving telescopic rod 403 and turn off the driving motor 320 when the two sets of guide assemblies 301 are positioning the solar panels. By filling the air cavity 3022 with gas at a certain pressure, the height of the transmission roller 304 is adjusted, and the transmission motor 3041 conveys the battery panel so that it enters the detection module from the external conveyor belt. Then, in the positioning operation, one of the guide components 301 pushes the battery panel. At this time, the transmission motor 3041 is self-locked, so that the transmission roller 304 does not rotate. When the two groups of guide components 301 contact the two sides of the battery panel respectively, the two groups of guide components 301 continue to move towards each other, which will cause the battery panel to generate a resistance force on the transmission roller 304, which will cause the gas in the air cavity 3022 to be compressed and the air pressure to increase. When the air pressure increases to a certain level, the air pressure switch is triggered, thereby confirming that the two groups of guide components 301 have clamped the battery panel. At this time, the drive telescopic rod 403 is started and the drive motor 320 is turned off.

[0072] In some optional specific embodiments, such as Fig.12 As shown, an air passage 3044 is provided at one end of the rotating shaft 3043, a negative pressure cavity is provided in the transmission roller 304, a plurality of air holes 3042 connected to the negative pressure cavity are evenly distributed on the surface of the transmission roller 304, the air passage 3044 is connected to an external air path for providing negative pressure to the negative pressure cavity, and an avoidance groove 3021 is provided on the side of the mounting roller seat 302 for movement of the external air path. When the guide assembly 301 lifts the battery panel, after the lifting is completed, the negative pressure cavity generates negative pressure, so that the air holes 3042 and the battery panel are adsorbed, the battery panel is fixed, and the movement is avoided during the shooting.

[0073] In some optional specific embodiments, such as Figure 2-12 As shown, two groups of guide seats 104 are installed on the base 101, and the lifting seat 103 is adapted to be installed between the two groups of guide seats 104. A hydraulic lifting rod is installed between the lifting seat 103 and the base 101, and a rack 311 is meshedly connected with a driven gear 307, and the driven gear 307 is fixedly installed in the gear seat 306. The two sides of the gear seat 306 are respectively connected with mounting shafts 308, and the mounting shaft 308 can be rotatably installed between the two groups of telescopic frames 309. A limiting plate 310 is installed between the two groups of telescopic frames 309, which is used to keep the driven gear 307 and the rack 311 in a meshing state. The gear seat 306 is fixedly connected with a connecting column 305, and the connecting column 305 is rotatably connected to the bottom of the mounting roller seat 302. The mounting roller seat 302 is connected with a vertical holding unit, which is used to keep the mounting roller seat 302 facing upward.

[0074] In some optional specific embodiments, such as Figure 2-11 As shown, the vertical holding unit includes a supporting plate 105 fixedly mounted on the guide seat 104, and two sets of slide grooves 106 are opened on the supporting plate 105. A slider 315 is adapted to be installed in the slide groove 106. The slider 315 can only move along the slide groove 106. The slider 315 is connected to a vertical telescopic rod 314, and the vertical telescopic rod 314 is fixedly connected to the bottom of the mounting roller seat 302. A rotating shaft is installed at the bottom of the mounting roller seat 302, and the rotating shaft is connected to the connecting column 305. When the solar panel is lifted, the lifting seat 103 is driven up and down by the hydraulic lifting rod, thereby driving the rack 311 to move up and down, and the rack 311 meshes with the driven gear 307 to rotate, so that the connecting column 305 rotates around the installation shaft 308. In this process, since the connecting column 305 is connected to the bottom of the installation roller seat 302 through a rotating shaft, and the vertical telescopic rod 314 is connected between the installation roller seat 302 and the slider 315, and the vertical telescopic rod 314 is connected to the slider 315, the rotational movement of the installation roller seat 302 is restricted, so that when the connecting column 305 rotates, the transmission roller 304 is always in contact with the bottom surface of the solar panel.

[0075] In some optional specific embodiments, such as Fig.10 As shown, the clamping assembly 401 includes a clamping plate 402 fixedly connected to a driving telescopic rod 403, a guide groove 404 is provided on the clamping plate 402, a T-shaped slide 405 is adapted to be installed in the guide groove 404, and a support plate 406 is fixedly connected to the T-shaped slide 405. After positioning is completed, during the lifting process, the two groups of support plates 406 clamp and fix the solar panel, and during the rising process of the solar panel, the two groups of support plates 406 rise accordingly to keep the solar panel stable.

[0076] In some optional specific implementations, such as Figure 2-11As shown, multiple groups of support columns 107 are installed on the side plate 102, and a top plate 501 is installed on the top of the support column 107. Multiple groups of sliding sleeves 603 are sleeved on the support column 107, and a peripheral side frame 601 is connected between the multiple groups of sliding sleeves 603. The peripheral side frame 601 and the upper end of the side plate 102 are connected to an electric lifting rod 602. The camera unit includes: a first camera 202, which is installed on the supporting plate 201 and is used to shoot the middle area of ​​the bottom of the solar panel during the lifting process of the solar panel; two groups of second cameras 204 are connected to a camera seat 203, and the camera seat 203 is arranged on both sides of the supporting plate 201, and is used to shoot the two side areas of the bottom of the solar panel during the lifting process of the solar panel; a third camera is installed on the bottom surface of the top plate 501, and is used to shoot the upper surface of the solar panel after the lifting is completed; multiple groups of fourth cameras are respectively arranged on the peripheral side frames 601, and are used to shoot the four sides of the solar panel after the lifting is completed.

[0077] In some optional specific embodiments, the display unit and the camera unit are installed at the same position, the display unit includes a laser light for displaying the hidden crack point, and the motion unit includes a universal driver for adjusting the direction of the laser light.
