[0002] The solar new energy industry has developed rapidly in China. Policy support and technological progress are the main driving forces for the future rapid development of our new energy industry. Photovoltaic production equipment has entered the era of automation. Due to the maturity and stability of production processes, the trend of replacing manual labor with automated equipment is becoming increasingly obvious. When producing photovoltaic modules, the junction box needs to be filled with AB glue to ensure the insulation performance of the junction box terminals and protect the junction box from external corrosion.

[0003] In the prior art, manual glue filling has always been used in the process of filling glue into the junction box. Because the sizes of photovoltaic modules are different, it is difficult to accurately position them, the positions of the junction boxes are different, it is difficult to determine the glue filling weight, the glue filling is uneven, and the process quality is not up to standard. In addition, manual glue filling needs to be linked with the stagnation of the front and rear stages on the production line, resulting in a long production cycle and increased production costs.

Specific embodiments

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 3 , the embodiments of the present invention include:

[0033] An automatic glue filling system, including a frame 100, on which a photovoltaic module 200 is placed and horizontally slides along the conveying track on the frame 100, and a junction box 300 is loaded on the photovoltaic module 200.

[0034] A positioning mechanism 400, a glue filling mechanism 500 and a photoelectric switch 600 are arranged on the frame, which can respectively solve the positioning problems of the photovoltaic module 200 and the junction box 300, the problem of uniform glue filling, and the problem of automatic switching of large and small components.

[0035] The automatic glue filling system further includes a controller 700, which is electrically connected to the photoelectric switch 600, the positioning mechanism 400 and the glue filling mechanism 500 respectively.

[0036] The photoelectric switch 600 is arranged at the end of the conveying track. The photoelectric switch 600 collects the size information of the photovoltaic module 200, the position information and glue filling information of the junction box 300, and then controls the positioning mechanism 400 and the glue filling mechanism 500 through the controller 700 to achieve uniform glue filling of the junction box 300.

[0037] The photoelectric type sensed by the photoelectric switch 600 is mutually adapted to the size information of the photovoltaic module 200. The photoelectric switch 600 can judge the size of the photovoltaic module 200 and automatically set the glue filling position and glue filling amount of the junction box 300 according to the size of the photovoltaic module 200.

[0038] According to the different sizes of the photovoltaic module 200, the photoelectric switch 600 at the set position can be used to judge the size of the photovoltaic module 200, and at the same time collect the position information and potting information of the junction box 300, and then transmit them to the controller 700. The potting position and potting amount are input into the internal program of the controller 700, so as to achieve accurate potting position and potting amount at low cost and comprehensively improve the potting quality.

[0039] The controller 700 receives the potting position information and feeds it back to the positioning mechanism 400, and realizes the horizontal positioning and vertical positioning of the photovoltaic module 200 through the positioning mechanism 400.

[0040] The controller 700 receives the potting position information and potting amount information and feeds them back to the potting mechanism 500, and realizes the positioning of the potting points of the junction box 300 and the uniform potting of the junction box 300 through the potting mechanism 200.

[0041] The positioning mechanism 400 includes a horizontal driving cylinder 401 and a vertical driving cylinder 402. A horizontal driving cylinder fixing plate 403 and a vertical driving cylinder fixing plate 404 are arranged on the conveying track. The horizontal cylinder fixing plate 403 and the vertical cylinder fixing plate 404 can move back and forth, left and right along the frame 100. The horizontal driving cylinder 401 is arranged on the horizontal cylinder fixing plate 403, and the vertical driving cylinder 402 is arranged on the vertical cylinder fixing plate 404.

[0042] A horizontal positioning jaw 405 is assembled on the horizontal driving cylinder 401, and a vertical positioning jaw 406 is assembled on the vertical driving cylinder 402. The horizontal driving cylinder 401 and the vertical driving cylinder 402 move horizontally and vertically under the action of the controller 700, driving the horizontal positioning jaw 405 and the vertical positioning jaw 406 to realize the horizontal positioning and vertical positioning of the photovoltaic module 200.

[0043] The current basic sizes of the photovoltaic module 200 are all 1956*992 and 1640*992. In view of this regular problem, both the horizontal driving cylinder 401 and the vertical driving cylinder 402 are rotary clamping cylinders. Further, both the horizontal positioning jaw 405 and the vertical positioning jaw 406 are nylon block positioning jaws, which can prevent the components from being scratched to the greatest extent.

[0044] The potting mechanism 500 includes a fixed seat 501, a stepping motor 502, a potting cylinder 503 and a potting tube 504. Symmetrically arranged slide rails 505 are provided on both sides of the fixed seat 501. The stepping motor 502 slides smoothly in the horizontal direction along the slide rails 505 on both sides. The potting cylinder 503 is arranged above the stepping motor 502, and the potting cylinder 503 can slide horizontally along the stepping motor 502.

[0045] The stepper motor is electrically connected to the controller, and the glue-filling cylinder is electrically connected to the controller. The movement of the stepper motor and the back-and-forth movement of the glue-filling cylinder achieve precise positioning of the glue-filling points.

[0046] The glue-filling cylinder 503 is drivingly connected to the glue-filling pipe 504 and is electrically connected to the controller 700. The controller 700 is operated and controlled through the human-machine interface touch screen 701. The back-and-forth movement of the glue-filling cylinder 503 drives the glue-filling pipe 504 to perform spot glue-filling on the junction box 300 according to the set glue-filling amount. After the glue-filling is completed, the glue-filling cylinder continues to move back and forth.

[0047] The glue-filling mechanism 500 also includes an alarm, which is electrically connected to the controller 700. When the glue is lacking or overflowing, it will automatically alarm.

[0048] After the glue-filling is completed, automatic glue discharging will be carried out, and the glue will be discharged into the glue discharging bucket 506 before it thickens.

[0049] After the photovoltaic module 200 enters the production line, according to the different sizes of the photovoltaic module 200, the photoelectric types sensed by the controller are also different. The controller 700 judges and calls the corresponding control program according to different photoelectric types, and then controls the lateral driving cylinder 401 for positioning. Immediately afterwards, the longitudinal driving cylinder 402 positions. At this time, the glue-filling mechanism 500 starts to move along the stepper motor 502 to the glue-applying position. The stepper motor 502 moves and the glue-filling cylinder 503 starts to move back and forth. After the glue-filling is completed, the lateral driving cylinder 401 and the longitudinal driving cylinder 402 are released, and the module stays on the subsequent production line.

[0052] b. The photoelectric switch 600 and the controller 700 are started. The photovoltaic module 200 enters the production line. The photoelectric switch 600 detects and judges the size of the photovoltaic module 200 on the production line, and automatically sets the glue-filling position and glue-filling amount of the junction box 300 according to the size of the photovoltaic module 200. Then, the data information of the glue-filling position and glue-filling amount of the junction box 300 is transmitted to the inside of the controller 700, and the controller 700 judges and calls the corresponding control program inside;

[0053] c. The positioning mechanism 400 receives the glue-filling position information of the controller 700. After the lateral driving cylinder 401 and the longitudinal driving cylinder 402 receive the data information of the glue-filling position, they perform lateral movement and longitudinal movement, and then drive the lateral positioning claw 405 and the longitudinal positioning claw 406 to achieve lateral positioning and longitudinal positioning of the photovoltaic module 200;

[0054] d. The stepper motor 502 and the potting cylinder 503 receive the potting position information and potting volume information from the controller 700, and control the trajectory of the stepper motor 502 through the human-machine interface touch screen 701. All parameters can be freely adjusted.

[0055] The stepper motor 502 slides horizontally along the slide rails 505 on both sides, and the potting cylinder 503 slides horizontally along the stepper motor 502. The movement of the stepper motor 502 and the back-and-forth movement of the potting cylinder 503 determine the precise position of the potting point.

[0056] f. After the potting tube 504 reaches the potting point, the potting cylinder 503 drives the potting tube 504 to perform spot potting on the junction box 300 according to the set potting volume, realizing uniform potting of the junction box 300.

[0057] g. After the potting is completed, the lateral drive cylinder 401 and the longitudinal drive cylinder 402 are released, and the photovoltaic module 200 with the junction box 300 is transferred to the subsequent production line.
