Description

Technical Field

[0001] This invention relates to the field of photovoltaic module processing technology, specifically to a photovoltaic panel edge grinding device. Background Technology

[0002] Solar energy refers to the thermal radiation energy of the sun, mainly manifested as sunlight. In modern times, it is generally used for power generation or to provide energy for water heaters. Solar photovoltaic panels are the main equipment for converting solar energy into electrical energy. During the production and manufacturing process of photovoltaic panels, the cut photovoltaic glass panels need to be deburred. Existing deburring devices can only process one photovoltaic glass panel at a time, resulting in low processing efficiency, incomplete polishing, residual burrs, poor polishing effect, inability to perform batch polishing, and complex structure and cumbersome operation.

[0003] To address the aforementioned issues, Chinese invention patent CN114654327B discloses a deburring device for the production of solar photovoltaic panels. This device uses a drive component to move a mounting frame on a processing platform, and a grinding component to grind and remove burrs from the photovoltaic panels. The mounting frame reciprocates and grinds multiple times, enabling simultaneous grinding of burrs on multiple photovoltaic panels. This results in high grinding efficiency, excellent grinding effect, and complete removal of burrs from photovoltaic panels. The device is also convenient to operate and easy to use.

[0004] However, in practical use, although the device can polish multiple photovoltaic glass panels simultaneously, it can only polish and remove burrs from one pair of parallel sides of the photovoltaic glass panel. After polishing the front and back sides of the photovoltaic glass panel, the panels need to be disassembled one by one, rinsed, and then reassembled layer by layer before the polishing components can polish the other pair of parallel sides of the photovoltaic glass panel. The polishing efficiency still needs to be improved. Summary of the Invention

[0028] The pair of adsorption fixing mechanisms 3 are respectively installed on the two ends of the moving base plate 24, and each of the adsorption fixing mechanisms 3 comprises an adsorption turntable 32 used to adsorb and fix the photovoltaic panel and a rotating motor 33 used to drive the adsorption turntable 32 to rotate.

[0029] The pair of front and rear distributed grinding roller group mechanisms 5 are slidably installed on the lower end of the grinding frame 11 in the front and rear directions and used to grind the front and rear edges of the photovoltaic panel.

[0030] The adjusting mechanism 4 is installed on the grinding frame 11 and used to synchronously drive the pair of grinding roller group mechanisms 5 to move away from or towards each other, so as to complete the centering positioning and grinding operation of the photovoltaic panel.

[0031] In order to avoid damage to the photovoltaic panel during the centering movement, a smooth pad layer can be attached and fixed to the upper surface of the adsorption turntable 32.

[0032] The working principle of the device is as follows: when starting to work, first, the photovoltaic panel to be processed is placed on the adsorption turntable 32 of the right adsorption fixing mechanism 3 (at this time, the left adsorption fixing mechanism 3 is located below the grinding frame 11), then the photovoltaic panel is adsorbed and fixed by the adsorption turntable 32 of the adsorption fixing mechanism 3, then the photovoltaic panel is moved to the position of the grinding roller group mechanism 5 by the moving mechanism 2, then the photovoltaic panel is released by the adsorption turntable 32 of the adsorption fixing mechanism 3, then the pair of grinding roller group mechanisms 5 are synchronously moved close to the photovoltaic panel by the adjusting mechanism 4, so that the photovoltaic panel is positioned to the middle position of the adsorption fixing mechanism 3, and the centering positioning is completed; then the photovoltaic panel is fixed by the adsorption turntable 32 of the adsorption fixing mechanism 3, and at the same time of the centering positioning, another photovoltaic panel is placed on the left adsorption fixing mechanism 3, then the grinding roller group mechanisms 5 are opened, the adsorption fixing mechanism 3 is moved right by the moving mechanism 2, and at this time, the side edge of the positioned photovoltaic panel can be ground.

[0033] After the grinding work of one pair of side edges of the photovoltaic panel is completed, the adjusting mechanism 4 drives the grinding roller group mechanism 5 to reset, and when the left photovoltaic panel moves below the grinding frame 11, the left adsorption fixing mechanism 3 releases the photovoltaic panel, then the adjusting mechanism 4 drives the grinding roller group mechanism 5 to approach the photovoltaic panel, so as to position the photovoltaic panel to the middle position of the adsorption fixing mechanism 3, then the left adsorption fixing mechanism 3 fixes the photovoltaic panel again, at the same time, the right adsorption fixing mechanism 3 drives the photovoltaic panel to rotate 90°, then the moving mechanism 2 drives the adsorption fixing mechanism 3 to move left, at this time, the grinding roller group mechanism 5 is opened, so as to grind the left photovoltaic panel;

[0034] After the grinding work of one pair of side edges of the photovoltaic panel is completed, the adjusting mechanism 4 drives the grinding roller group mechanism 5 to reset, and when the left photovoltaic panel moves below the grinding frame 11, the left adsorption fixing mechanism 3 releases the photovoltaic panel, then the adjusting mechanism 4 drives the grinding roller group mechanism 5 to approach the photovoltaic panel, so as to position the photovoltaic panel to the middle position of the adsorption fixing mechanism 3, then the left adsorption fixing mechanism 3 fixes the photovoltaic panel again, at the same time, the right adsorption fixing mechanism 3 drives the photovoltaic panel to rotate 90°, then the moving mechanism 2 drives the adsorption fixing mechanism 3 to move left, at this time, the grinding roller group mechanism 5 is opened, so as to grind the left photovoltaic panel;

[0035] After the grinding work of one pair of side edges of the photovoltaic panel is completed, the adjusting mechanism 4 drives the grinding roller group mechanism 5 to reset, and when the left photovoltaic panel moves below the grinding frame 11, the left adsorption fixing mechanism 3 releases the photovoltaic panel, then the adjusting mechanism 4 drives the grinding roller group mechanism 5 to approach the photovoltaic panel, so as to position the photovoltaic panel to the middle position of the adsorption fixing mechanism 3, then the left adsorption fixing mechanism 3 fixes the photovoltaic panel again, at the same time, the right adsorption fixing mechanism 3 drives the photovoltaic panel to rotate 90°, then the moving mechanism 2 drives the adsorption fixing mechanism 3 to move left, at this time, the grinding roller group mechanism 5 is opened, so as to grind the left photovoltaic panel;

[0036] As a further scheme, the grinding table 1 is provided with a moving sliding groove 22; the moving mechanism 2 comprises a moving motor 21 and a moving lead screw 23, the moving lead screw 23 is rotatably installed in the moving sliding groove 22, and the moving block at the lower end of the moving seat plate 24 is threadedly sleeved on the moving lead screw 23;

[0037] The moving motor 21 is fixedly installed at the end of the grinding table 1, and the output end of the moving motor 21 is drivingly connected with the shaft end of the moving lead screw 23.

[0038] The working principle of the moving mechanism 2 is that when the photovoltaic panel needs to be moved, the moving motor 21 is started, the moving lead screw 23 is driven to rotate by the moving motor 21, the moving block on which the moving lead screw 23 is screwed is driven to move, and the left and right horizontal movement of the photovoltaic panel can be realized by the forward and reverse rotation of the moving motor 21, thereby facilitating the grinding roller group mechanism 5 to grind the side surface of the photovoltaic panel.

[0039] As a further scheme, the adsorption fixing mechanism 3 further comprises a fixing frame 31 installed on the upper end of the moving seat plate 24.

[0040] The adsorption rotating disc 32 is rotatably installed on the fixing frame 31, a plurality of adsorption holes are distributed and formed on the adsorption rotating disc 32, and a vacuum pipe 34 is further installed on the side wall of the adsorption rotating disc 32. The inner side end of the vacuum pipe 34 is in communication with the adsorption holes, and a vacuum air pump 35 is installed on the vacuum pipe 34.

[0041] The rotating motor 33 is fixedly installed on the lower end of the fixing frame 31, and the output end of the rotating motor 33 is drivingly connected with the shaft end of the adsorption rotating disc 32. In this embodiment, a hollow cavity is arranged in the adsorption rotating disc 32, and the vacuum pipe 34 and the adsorption holes are in communication with the hollow cavity.

[0042] The working principle of the adsorption fixing mechanism 3 is that after the photovoltaic panel is placed on the adsorption rotating disc 32, the vacuum air pump 35 is started to exhaust air, so that the air in the adsorption rotating disc 32 is exhausted, thereby forming a negative pressure in the adsorption rotating disc 32, and the photovoltaic panel is adsorbed through the adsorption holes. When the photovoltaic panel needs to be rotated, the rotating motor 33 is started to drive the adsorption rotating disc 32 to rotate, thereby realizing the rotation of the photovoltaic panel.

[0043] As a further scheme, the grinding frame 11 is further provided with adjusting sliding grooves 43 on the front and rear sides of the upper end thereof, and adjusting sliding seats 44 are slidingly installed in the adjusting sliding grooves 43.

[0044] The grinding roller group mechanism 5 comprises a grinding seat 51 installed on the lower end of the adjusting sliding seat 44, a grinding groove 52 is formed in the side wall of the grinding seat 51, a grinding roller 53 is rotatably installed in the grinding groove 52, and a grinding motor 54 is further installed on the lower end of the grinding seat 51. The output end of the grinding motor 54 is drivingly connected with the shaft end of the grinding roller 53.

[0045] The working principle of the grinding roller group mechanism 5 is that during grinding, the grinding motor 54 is started to drive the grinding roller 53 to rotate, thereby realizing the polishing work on the side surface of the photovoltaic panel.

[0046] The adjusting mechanism 4 comprises a pair of adjusting seats 41 installed on the upper end of the grinding frame 11, and adjusting lead screws 45 are rotatably installed on the adjusting seats 41.

[0047] The adjusting slide 44 is threadedly sleeved on the adjusting lead screw 45, and the adjusting seat 41 is further provided with an adjusting motor 42 at the end thereof, the output end of the adjusting motor 42 is drivingly connected with the shaft end of the adjusting lead screw 45, and the adjusting lead screw 45 is provided with a forward threaded section and a reverse threaded section with opposite thread directions at the front end and the rear end thereof respectively, and the forward threaded section and the reverse threaded section are respectively threadedly inserted and matched with the corresponding adjusting slide 44.

[0048] The working principle of the adjusting mechanism 4 is that when it is needed to adjust the position of the grinding roller group mechanism 5, the adjusting motor 42 is started, the adjusting lead screw 45 is driven to rotate by the adjusting motor 42, the adjusting slide 44 threadedly sleeved on the adjusting lead screw 45 is moved along the adjusting slot 43, and thus the position of the grinding roller group mechanism 5 at the lower end of the adjusting slide 44 is adjusted, so that the grinding roller group mechanism 5 is conveniently close to the side surface of the photovoltaic panel, and thus the grinding work is facilitated.

[0049] In the embodiment, on the one hand (when the grinding roller group mechanism 5 is not working), after the photovoltaic panel is released by the adsorbing turntable 32, the two grinding roller group mechanisms 5 on the two sides are brought close to each other by the adjusting mechanism 4, the grinding rollers 53 on the two sides can be centered and positioned on the photovoltaic panel, and the photovoltaic panel can be moved to the middle position of the adsorbing and fixing mechanism 3, and thus the subsequent grinding is facilitated.

[0050] On the other hand (when the grinding roller group mechanism 5 is working, and the photovoltaic panel is adsorbed and fixed by the adsorbing turntable 32), the grinding roller 53 is driven to rotate by the grinding motor 54, at the same time, the photovoltaic panel is moved by the moving mechanism 2, and thus the side surface of the photovoltaic panel can be ground.

[0051] In addition, since the distance between the two grinding roller group mechanisms 5 can be adjusted by the adjusting mechanism 4, the two grinding roller group mechanisms 5 in the embodiment can polish the side edges of photovoltaic panels with different width sizes, and the processing application range is wider.

[0052] As a further specific scheme, the embodiment further comprises a central processing unit, the central processing unit is electrically connected with a parameter input module, an alarm module and a photoelectric switch installed on the adsorbing turntable 32; the parameter input module can be specifically a keyboard and / or a mouse, and the specific size of the photovoltaic panel to be processed currently can be input to the central processing unit through the parameter input module; the photoelectric switch is used to detect whether the photovoltaic panel is placed on the adsorbing turntable 32.

[0053] The adjusting motor 42 is further provided with an encoder I for detecting the rotation number of the adjusting motor 42;

[0054] The moving motor 21 is further provided with an encoder I for detecting the rotation number of the moving motor 21;

[0055] The encoder one and the encoder two are electrically connected with the signal input end of the central processor; the rotating number of the adjusting motor 42 is detected by the encoder one, and the rotating number information is sent to the central processor, and the interval between the current pair of grinding roller group mechanisms 5 can be obtained by the central processor after calculation, when the interval between the grinding roller group mechanisms 5 is the same as the width dimension between the front and back of the photovoltaic panel, the central processor controls the adjusting motor 42 to stop, at this time, the grinding rollers 53 of the pair of grinding roller group mechanisms 5 are respectively attached to the front and back sides of the photovoltaic panel;

[0056] Similarly, the rotating number of the moving motor 21 is detected by the encoder one, and the rotating number information is sent to the central processor, and the position of the current moving seat plate 24 can be obtained by the central processor after calculation, when the moving seat plate 24 reaches the preset position, the central processor controls the moving motor 21 to stop.

[0057] The central processor is also electrically connected with the adjusting motor 42, the grinding motor 54, the rotating motor 33, the adsorption control end (i.e. the control end of the vacuum air pump 35) of the adsorption turntable 32 and the signal control end (i.e. the control end of the moving motor 21) of the moving mechanism 2 respectively.

[0058] In specific work, the specific size of the current photovoltaic panel to be processed can be input to the central processor through the parameter input module in advance;

[0059] Then, the photovoltaic panel to be processed can be placed on the adsorption turntable 32 of the adsorption fixing mechanism 3 by the external mechanical arm, and the signal is sent to the central processor after the placement signal is detected by the photoelectric switch, the central processor controls the vacuum air pump 35 to work, and the running power parameter of the vacuum air pump 35 is collected at the same time, if the running power parameter of the current vacuum air pump 35 is lower than the normal range, it is indicated that the adsorption turntable 32 does not completely adsorb and fix the photovoltaic panel, then the central processor controls the alarm module to alarm; if the running power parameter of the current vacuum air pump 35 is in the normal range, it is indicated that the adsorption turntable 32 has completely adsorbed and fixed the photovoltaic panel, and the next step is entered;

[0060] The central processor controls the moving motor 21 to work, when the photovoltaic panel to be processed is moved to the grinding station, the central processor controls the moving motor 21 to stop, and also controls the vacuum air pump 35 to stop, so that the adsorption turntable 32 releases the photovoltaic panel;

[0061] Then, the central processor controls the adjusting motor 42 to work, under the driving of the adjusting motor 42, the pair of grinding roller group mechanisms 5 move oppositely, in the process, the grinding roller 53 on one side first contacts the corresponding side edge of the photovoltaic panel, under the pushing, the photovoltaic panel slides on the adsorbing turntable 32, after the grinding roller 53 on the other side also contacts the corresponding side edge of the photovoltaic panel, the central processor controls the adjusting motor 42 to stop, thereby completing the centering positioning of the photovoltaic panel, ensuring that the two grinding rollers 53 can simultaneously grind the pair of side edges of the photovoltaic panel in the subsequent process;

[0062] Then, the central processor controls the vacuum pump 35 to continue working, re-adsorbs and fixes the photovoltaic panel, then the central processor controls the grinding motor 54 to work, at the same time, the central processor also controls the moving motor 21 to work, thereby grinding the pair of side edges of the photovoltaic panel.
