[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, a photovoltaic panel grinding device includes a longitudinal conveyor belt 1, a transverse conveyor belt 2, a grinding wheel 3 and a reversing mechanism 4.

[0021] like Figure 1 As shown, the longitudinal conveyor belt 1 is horizontally arranged on the ground, and the photovoltaic panels are transported along the longitudinal direction on the longitudinal conveyor belt 1. The transverse conveyor belt 2 is horizontally arranged on the ground and perpendicular to the longitudinal conveyor belt 1, and the photovoltaic panels are transported along the width direction on the transverse conveyor belt 2.

[0022] like Figure 1 As shown, the grinding wheel 3 is vertically connected to both sides of the middle position of the longitudinal conveyor belt 1 and the transverse conveyor belt 2. The grinding wheel 3 is thin in the middle and thick at both ends, and can grind out arc-shaped chamfers around the photovoltaic panel.

[0023] like Figure 1 、 Figure 2 As shown, the reversing mechanism 4 is arranged between the longitudinal conveyor belt 1 and the transverse conveyor belt 2 , and the reversing mechanism 4 includes a support frame 41 , a transmission roller 42 , a guide wheel 43 and a limiting roller 44 .

[0024] like Figure 1 、 Figure 2 As shown, a support frame 41 is disposed between the longitudinal conveyor belt 1 and the transverse conveyor belt 2. A drive roller 42 is horizontally connected to the support frame 41 and rotates in the same direction as the longitudinal conveyor belt 1. A guide wheel 43 is tilted and disposed on the outer wall of the drive roller 42, facing the transverse conveyor belt 2. A limit roller 44 is vertically connected to the rear end of the support frame 41.

[0025] When the photovoltaic panel needs to be ground, the photovoltaic panel is placed on the longitudinal conveyor belt 1 so that the length direction of the photovoltaic panel is the same as the transmission direction of the longitudinal conveyor belt 1. As the longitudinal conveyor belt 1 is continuously transmitted, the grinding wheel 3 on the longitudinal conveyor belt 1 is used to realize automatic grinding of the two long sides of the photovoltaic panel.

[0026] After grinding is completed, the photovoltaic panel is gradually transferred to the transmission roller 42 until the photovoltaic panel hits the limiting roller 44. Under the cooperation of the guide wheel 43 on the transmission roller 42, the photovoltaic panel is automatically squeezed and transferred along the horizontal direction and automatically enters the horizontal conveyor belt 2.

[0027] With the continuous transmission of the transverse conveyor belt 2, the grinding wheel 3 on the transverse conveyor belt 2 is used to realize automatic grinding processing in the two short sides of the photovoltaic panel, thereby completing the four-side grinding processing of the photovoltaic panel at one time, improving the grinding efficiency and production efficiency.

[0028] like Figure 1 、 Figure 3 、 Figure 4 As shown, a processing tube 5 is provided on the longitudinal conveyor belt 1 and is located behind the grinding wheel 3. A pair of arc-shaped fine grinding blocks 51 are provided in the processing tube 5. A guide rod 52 is provided on the fine grinding block 51, and a guide groove 53 for the guide rod 52 to slide is provided on the processing tube 5.

[0029] like Figure 3 、 Figure 4 As shown, a driving mechanism 6 for controlling the relative sliding of a pair of fine grinding blocks 51 is provided on the processing tube 5 . The driving mechanism 6 includes a rotating shaft 61 , a cam 62 and a pair of driving rods 63 .

[0030] like Figure 3 、 Figure 4 As shown, the shaft 61 is horizontally connected to the processing tube 5, and the cam 62 is triangularly arranged on the shaft 61. One end of a pair of driving rods 63 is respectively connected to the two vertex positions of the cam 62, and the other end is connected to the lower end of the fine grinding block 51.

[0031] Because photovoltaic panels are long and narrow, workers will hold the two long sides of the photovoltaic panels when moving them, so they must ensure that the long sides are absolutely smooth to avoid scratching their palms.

[0032] Therefore, when the two long sides of the photovoltaic panel are ground, the photovoltaic panel enters the processing tube 5. At this time, the rotating shaft 61 is controlled to rotate, and the rotating shaft 61 drives the cam 62 to rotate, and the cam 62 and the driving rod 63 form a crank-connecting rod structure to control the vertical reciprocating sliding of the fine grinding block 51.

[0033] And with the cooperation of the guide rod 52 on the fine grinding block 51 and the guide groove 53 on the processing tube 5, a pair of fine grinding blocks 51 slide relative to each other, and the sliding direction is the arc direction, which just fits the arc chamfer of the photovoltaic panel, realizing the secondary fine grinding of the photovoltaic panel and preventing scratches on the palm during transportation.

[0034] like Figure 1 、 Figure 5 As shown, a transfer platform 7 is provided at the tail end of the transverse conveyor belt 2 , a cleaning box 71 is provided at the front end of the transfer platform 7 , and nozzles 72 are provided at both ends of the cleaning box 71 .

[0035] like Figure 5As shown, two groups of air-drying hoods 73 are spaced apart in the middle of the transfer platform 7 , and each air-drying hood 73 is provided with a fan 74 for blowing air downwards. The transfer platform 7 is provided with a turning mechanism 8 located between the pair of air-drying hoods 73 .

[0036] like Figure 5 As shown, the flip mechanism 8 includes a mounting frame 81, a flip shaft 8261, and a pair of clamping plates 83. The mounting frame 81 is vertically mounted on the ground, the flip shaft 8261 is horizontally connected to the mounting frame 81, and the clamping plates 83 are located at both ends of the flip shaft 8261. The clamping plates 83 are provided with slots 84 for inserting the photovoltaic panels, and the inner walls of the slots 84 are provided with anti-slip strips 85.

[0037] When all four sides of the photovoltaic panel are ground, the photovoltaic panel is transferred on the transfer platform 7. At this time, the photovoltaic panel first enters the cleaning box 71. At this time, the nozzle 72 flushes both sides of the photovoltaic panel to wash away the grinding powder and complete automatic cleaning.

[0038] The photovoltaic panel then enters the first air-drying hood 73, where the fan 74 on the first air-drying hood 73 is used to air-dry the top surface of the photovoltaic panel. The photovoltaic panel then exits the first air-drying hood 73 and enters the slots 84 on the pair of clamping plates 83. The flip shaft 8261 then controls the pair of clamping plates 83 to flip the photovoltaic panel, turning it over and automatically placing it on the second half of the transfer platform 7.

[0039] The photovoltaic panel then enters the second air-drying hood 73, and the fan 74 on the second air-drying hood 73 is used to air-dry the lower surface of the photovoltaic panel, completing automatic cleaning and drying after grinding, realizing continuous production and processing of the photovoltaic panel, thereby improving grinding efficiency and production efficiency.

[0040] like Figure 6 、 Figure 7 As shown, the tail end of the transfer platform 7 is connected to a discharge platform 9, which is used to transport photovoltaic panels. A gantry 91 is located at the beginning of the discharge platform 9, extending along its length. A storage barrel 92 for storing quick-drying adhesive is mounted on the gantry 91. A discharge nozzle 93 is located at the lower end of the storage barrel 92, tilted backwards, to contact the surface of the photovoltaic panel.

[0041] like Figure 6 、 Figure 7 As shown, a solenoid valve 94 is installed on the discharge nozzle 93, and a push button switch 95 is installed on the upper end surface of the gantry 91 to control the opening and closing of the solenoid valve 94. A lever 96 is vertically installed on the gantry 91. The middle part of the lever 96 is rotatably connected to the gantry 91, and a torsion spring 97 is installed at the rotation position. The lower end of the lever 96 is used to contact and tilt the photovoltaic panel, and the upper end is used to press the push button switch 95.

[0042] After the photovoltaic panel is cleaned, it is transferred to the unloading platform 9 and transported backward on the unloading platform 9. When the photovoltaic panel is transported to the position of the lever 96, the photovoltaic panel pushes the lever 96 to flip, and the lever 96 presses the button switch 95 and controls the solenoid valve 94 to open. At this time, the glue in the storage barrel 92 overflows from the discharge nozzle 93 and is applied to the photovoltaic panel in a long strip of glue. The glue then dries automatically and forms a hard glue strip.

[0043] When the photovoltaic panel is separated from the lever 96, the lever 96 is reversely rotated and reset under the action of the torsion spring 97. At this time, the lever 96 is separated from the button switch 95, and then the solenoid valve 94 is closed, and the photovoltaic panel continues to be transported backward. This reciprocating process is carried out to achieve the glue coating operation of each photovoltaic panel.

[0044] Because the photovoltaic panels have hard adhesive strips, when the photovoltaic panels are stacked, there is space between the panels, preventing them from sticking together, making it easier to remove the panels. The adhesive strips also provide a certain degree of shock absorption, preventing damage during transportation. Furthermore, the adhesive strips can be easily removed, making the use of the photovoltaic panels even more convenient.

[0045] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
