Detailed Description
The following description is only for the purpose of disclosing the invention so as to enable a person skilled in the art to practice the invention. The embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other arrangements without departing from the spirit and scope of the invention.
As shown in fig. 1 and fig. 2, the invention provides a solar cell multi-track series welding system, which can continuously and uninterruptedly feed and weld a solar cell and a welding strip, greatly improve the productivity, and avoid the waste of the productivity. Specifically, the solar cell multi-track series welding system comprises a rack 10, a plurality of series welding platform groups 20, a welding strip feeding device 30, a solar cell feeding device 40 and a heating device 50.
The frame 10 has a plurality of rails 11, the rails 11 being adapted to movably mount the series welding platform set 20. The tracks 11 are distributed parallel and spaced apart.
The series welding platform sets 20 are movably mounted on the rails 11 in a one-to-one correspondence, in other words, the series welding platform sets 20 can move along the rails 11. Each series welding platform group 20 is formed by connecting a plurality of welding platforms 21 in series side by side. Each soldering station 21 can place and position a solar cell and the soldering ribbon correspondingly. In this way, each series welding platform set 20 can place and position a plurality of solar cells and solder strips required by series welding.
In the present embodiment, the number of the welding platforms 21 of each series welding platform set 20 is plural, and the welding platforms 21 are connected in series side by side, that is, the welding platforms 21 are connected in series. Any two adjacent welding platforms 21 are locked by a fastener such as a screw, and relative movement is prevented.
The number of soldering lands 21 depends on the number of strings of solar cells that are finally required. For example, if a single string of solar cells comprises 10 solar cells, 10 soldering lands 21 are required to be connected in series. The greater the number of soldering lands 21 connected in series, the greater the number of pieces of solar cells in a string that can be soldered. Alternatively, the number of the welding stages 21 is 10 or 12.
The solder strip feeding device 30 is disposed on the frame 10, and the solder strip feeding device 30 sequentially and alternately carries the solder strip to the soldering lands 21 of the series welding land groups 20. The solder strip is a conductor for being soldered to the interconnection electrodes of two adjacent solar cells to connect the solar cells in series. In the conventional technology, a solder strip used for welding the solar cells in series is a long and flat sheet-shaped body with a rectangular cross section, and the solder strip is called a flat solder strip. In the present disclosure, the solder strip includes a conventional tin-plated copper flat strip (also called a flat solder strip) and an emerging special-shaped solder strip. Wherein the special-shaped solder strip refers to a solder strip with a cross section of other shapes such as triangle or circle, except for flat solder strips. The welding strip with the triangular cross section is also called a fillet welding strip or a special-shaped welding strip and is one of special-shaped welding strips.
The solar cell feeding device 40 is disposed on the rack 10, and the solar cell feeding device 40 sequentially and alternately carries the solar cells to the soldering platforms 21 of the series soldering platform groups 20 and aligns the interconnection electrodes of the solar cells with the corresponding solder strips. Alternatively, the solder ribbon feeding device 30 and the solar cell sheet feeding device 40 are respectively located at two opposite sides of the frame 10.
The solar cell sheet feeding device 40 includes a feeding basket 41, a visual inspection mechanism (not shown), and a grasping mechanism 43. The material loading flower basket 41 is a container dedicated to the solar cell, and is movably disposed on the rack 10 for placing the solar cell. Generally, the loading basket 41 can be used for placing a stack of several solar cells.
The visual inspection mechanism is disposed at the bottom of the frame 10 and has a visual inspection station. The visual detection mechanism utilizes an industrial camera with high resolution to photograph the grid lines and the interconnection electrodes of the solar cell in a photographing mode so as to detect whether the solar cell to be loaded has defects. Meanwhile, the vision detection mechanism calculates the position of the solar cell, and sends the position correction data to the grabbing mechanism 43, so that the grabbing mechanism 43 can accurately transfer the solar cell to the welding platform 21 according to the correction data.
The gripping mechanism 43 has suction cups. The grasping mechanism 43 grasps the solar cell from the feeding basket 41 and transfers the solar cell to the visual inspection station of the visual inspection mechanism with the light receiving surface facing downward, and the visual inspection mechanism photographs the light receiving surface of the solar cell from below the solar cell to perform defect detection and position detection and transmits data to the grasping mechanism 43. The grabbing mechanism 43 transfers the solar cell pieces to the welding platforms 21 of the series welding platform groups 20 according to the data.
The solar cell piece feeding device 40 further comprises a rough and smooth platform, a defect detection mechanism and a soldering flux spraying mechanism. Before the solar cell is transferred to the vision inspection station of the vision inspection mechanism 42, the grabbing mechanism 43 transfers the solar cell to a rough-leveling and translating station for rough position calibration. And the defect detection mechanism detects the defects of the solar cell. The soldering flux spraying mechanism sprays soldering flux on the interconnected electrodes of the solar cells so as to facilitate later welding.
Alternatively, the number of the series welding platform sets 20 is two, and the two series welding platform sets 20 are installed on two sides of the rack 10 in parallel. Obviously, the number of the rails 11 is correspondingly two, and the two rails 11 are distributed on two sides of the frame 10. The two series welding platform groups 20 respectively feed the solder strip and the solar cell through the same solder strip feeding device 30 and the solar cell feeding device 40.
Alternatively, the number of the series welding platform sets 20 is four, and four series welding platform sets 20 are arranged in parallel side by side in two sets on two sides of the rack 10. Obviously, the number of the rails 11 is also four, and four rails 11 are distributed in two groups in parallel on two sides of the rack 10. The two series welding platform groups 20 of each group are used for feeding the welding strip through the same welding strip feeding device 30. Since one solar cell feeding device 40 is enough to supply four rail feeding requirements, the four series soldering platform sets 20 feed solar cells through the same solar cell feeding device 40. The solar cell sheet feeding device 40 is located between the two series welding platform sets 20, that is, the two series welding platform sets 20 are separated by the solar cell sheet feeding device 40.
The heating device 50 is disposed on the frame 10 and is used for heating the solar cell at a high temperature, so that the solder strip and the interconnection electrode of the solar cell are welded together, thereby realizing series welding. In operation, the series welding platform sets 20 sequentially and alternately move to the heating area of the heating device 50, and the heating device 50 heats and welds the solar cells on each series welding platform set 20, so that the solar cells are series-welded together.
Alternatively, the number of the heating devices 50 is multiple and is consistent with the number of the series welding platform groups 20, and the heating devices 50 heat and weld the solar cells on each series welding platform group 20 in a one-to-one correspondence manner. That is, each series soldering platform group 20 is correspondingly configured with one heating device 50 to heat the solar cell, and since the heating soldering process needs to take a certain time, the arrangement of a plurality of heating devices 50 can avoid the problems that a plurality of series soldering platforms 20 are crowded and the heating needs to wait for the time consumption.
In the present embodiment, the heating device 50 employs infrared heating, and includes an infrared lamp box 51 and a cooling device 52, where the infrared lamp box 51 includes a plurality of infrared lamps. The cooling device 52 is installed on top of the infrared lamp box 51 to cool the infrared lamp box 51. Optionally, in the present embodiment, the cooling device 52 is a fan.
The heating device 50 further includes a support frame 53, and the support frame 53 stands on one side of the rail 11. The infrared lamp box 51 and the cooling device 52 are both mounted on the support frame 53 and located above the rail 11. During heating welding, the series welding platform set 20 moves to a position right below the heating device 50, and the infrared lamp box 51 is started to heat the solar cells and the solder strips placed on the series welding platform set 20 at a high temperature.
The solar cell slice-level track series welding system further comprises a blanking device (not shown in the figure) and an el (electroluminescence) detection device (not shown in the figure). The EL detection device utilizes the electroluminescence principle of the solar cell and utilizes the high-resolution infrared camera to shoot near-infrared images of the solar cell, so that the welding defects of the solar cell, such as poor welding, hidden cracks, splinters and the like, can be judged, and the welding quality can be clearly and effectively detected. The EL detection device comprises a high-definition infrared camera, a power-on clamping mechanism, a camera bellows, an external display, a controller and the like. And the manual visual detection mainly detects defects of welding white exposure, deviation and the like. After the battery string with the set length is welded, the welding platform 21 moves to a blanking position, the blanking device sequentially and alternately grabs the solar battery pieces on the welding platform 21 of each series welding platform group 20 to the EL detection device to detect welding defects, and meanwhile, the welding platform 21 of the series welding platform group 20 returns to an initial loading position to start the next round of processing. After the EL detection is finished, the blanking device sequentially and alternately grabs the solar cell to a preset position and turns over the solar cell by a preset angle so as to allow manual visual detection. And manually placing the judged finished product or bad battery string into different blanking boxes respectively.
When there are a plurality of series welding platform sets 20 and tracks 11, for example, two or four, the feeding device (not shown) and the el (electroluminescence) detecting device may be one, and the series welding platform sets 20 on the tracks 11 share one feeding device and one el (electroluminescence) detecting device.
By arranging the EL detection device, the quality of the welding surface and the series welding points of the equipment can be fed back to production operation and process research personnel in time, and the solar cell with abnormal quality can be sorted out in time.
It should be noted that if the design, manufacture and operation of the subsequent multi-track series welding system for solar cells are more stable, the frequency of abnormal welding quality is less, and the EL detection system can be removed timely, so as to save space.
In particular, in this embodiment, the solar cell multi-track series welding system can realize series welding of the solar cell by using the flat solder strip and the special-shaped solder strip, that is, realize feeding of the special-shaped solder strip and positioning alignment of the special-shaped solder strip and the solar cell. The number of the welding strip feeding devices 30 is two, one of the welding strip feeding devices is a flat welding strip feeding device 30A, and the other welding strip feeding device is a special-shaped welding strip feeding device 30B.
The special-shaped solder strip feeding device 30B is used for feeding the special-shaped solder strip, that is, the special-shaped solder strip is conveyed to the welding platform 21, so that the special-shaped solder strip is aligned with the interconnection electrode on one surface of the solar cell. For convenience of description, the following description will be made by taking the triangular solder strip as an example of the special-shaped solder strip W, and the principle of the present invention for feeding the triangular solder strip is explained. The profile strip feeding device 30B includes a hand 31B and a first movement module 32B.

The hand grip 31B further includes a first air cylinder 313B, the first air cylinder 313B is mounted on the frame 3112B and connected to the first pressing pin 312B, and the first air cylinder 313B pushes the first pressing pin 312B to press the first positioning groove 3111B, so that the first pressing pin 312B presses the special-shaped welding strip W placed in the first positioning groove 3111B.
The hand grip 31B is mounted to the first motion module 32B. After the special-shaped welding strip W is placed in the first positioning groove 3111B of the gripper 31B, the first pressing pin 312B presses the special-shaped welding strip W, and the first motion module 32B drives the gripper 31B to move and carries the special-shaped welding strip W to the welding platform 21.

And then the heating device 50 heats the solar cell, so that the flat welding strip and the special-shaped welding strip are respectively welded and fixed with the two sides of the solar cell to complete series welding. Finally, the second motion module drives the second presser pin 62 and the third presser pin 63 to axially ascend, and the press-fit state is released.
