[0029] The barcode sticking mechanism for photovoltaic cells is disclosed in the embodiment of the present application.

[0030] Reference is made to Figure 1 The barcode sticking mechanism for photovoltaic cells comprises a machine frame 1, and a channel is formed through the machine frame 1. A transfer assembly 2 is arranged in the channel, and the transfer assembly 2 is installed on the machine frame 1 to drive the photovoltaic battery plate 8 to move along the X axis.

The space in the machine frame 1 is divided into left and right areas by the transfer assembly 2. The left area is used for installing small materials on the photovoltaic battery plate 8, and the right area is used for sticking barcodes.

[0031] Reference is made to Figure 1 and Figure 2The rack 1 is slidably installed with a crossbar 11 moving along the Y axis, the crossbar 11 spans above the transfer assembly 2, the crossbar 11 is driven by a Y axis linear movement module 12, the crossbar 11 is installed with an X axis linear movement module 13 on the left and right sides respectively, two moving ends of the two X axis linear movement modules 13 are respectively installed with a first code sticking assembly 4 for sticking a bar code on the bottom surface of the photovoltaic cell panel 8 and a second code sticking assembly 5 for sticking a bar code on the bottom surface of the photovoltaic cell string. Two bar code printing assemblies 6 are installed on one side of the transfer assembly 2 at intervals, and the two bar code printing assemblies 6 correspond to the first code sticking assembly 4 and the second code sticking assembly 5 respectively. The crossbar 11 drives the first code sticking assembly 4 and the second code sticking assembly 5 to reciprocate between the bar code printing assemblies 6 and the transfer assembly 2. A lifting assembly 7 is installed on one side of the rack 1 close to the second code sticking assembly 5, for lifting the end of the cell string and separating it from the cell panel 8.

[0032] The photovoltaic assembly flows from the previous process to one end of the transfer assembly 2, the strip-shaped cell string is laid on the glass cell panel 8, the cell panel 8 is laid on the transfer assembly 2, the transfer assembly 2 moves the cell panel 8 through the channel along the X axis to the inside of the rack 1, and stops after reaching the preset processing station; At this time, the alignment assembly 3 starts to abut against the side edge of the cell panel 8, forcing the cell panel 8 to slide on the transfer assembly 2, aligning the position of the cell panel 8, and fixing the cell panel 8. The cell panel 8 positioning work is completed.

[0033] In this process, the two bar code printing assemblies 6 respectively print a bar code with the code face up, at this time the length direction of the bar code is parallel to the X axis. The crossbar 11 drives the first code sticking assembly 4 and the second code sticking assembly 5 to move along the Y axis in the direction close to the bar code printing assembly 6, and sucks the printed bar code. Then the crossbar 11 moves towards the cell panel 8.

During the sticking process, the lifting assembly 7 presses the cell string from above to improve the firmness of the sticking. The sticking work of the two bar codes is completed.

[0035] The horizontal bar 11 drives the first code pasting assembly 4 and the second code pasting assembly 5 away from the battery plate 8, the lifting assembly 7 loosens the end of the battery string, and the battery plate 8 naturally falls onto the battery plate 8. The normalizing assembly 3 loosens the control of the battery plate 8, and the transfer assembly 2 starts to move the pasted battery plate 8 out of the rack 1 through the channel.

An alignment wheel 314 is rotatably installed on the top wall of the alignment mounting plate 313 through a rotating shaft, and the axis of the alignment wheel 314 is vertically arranged. When the alignment jacking cylinder 312 drives the alignment wheel 314 to be at the lowest point, the alignment wheel 314 is completely retracted below the conveying belt 21; when the alignment jacking cylinder 312 drives the alignment wheel 314 to rise to the highest point, the alignment wheel 314 is higher than the conveying belt 21, and the outer side wall of the alignment wheel 314 can abut against the side wall of the battery plate 8.

After processing is completed, the normalizing wheels 314 and the normalizing blocks 323 are away from the side wall of the battery plate 8, the normalizing jacking cylinder 312 drives the normalizing wheels 314 to completely retract below the conveying belt 21, and the conveying belt 21 starts to drive the battery plate 8 to leave the rack 1 through the passage.

A bottom end of a free end of the second Z-axis linear movement module 51 is fixedly installed with a compensation servo motor 52, an output end of the compensation servo motor 52 is installed with the rotary seat 43, a side wall of the rotary seat 43 is fixedly installed with the turnover motor 44, a motor shaft of the turnover motor 44 is fixedly connected with the turnover arm 45, and the turnover arm 45 can rotate in the vertical direction. One end of the turnover arm 45 is installed with the vacuum chuck 46. In the embodiment, the turnover arm 45 can be replaced by a T-shaped plate, and the vacuum chuck 46 can be selected in different models to adapt to different bar codes.

[0046] The principle of the bar code preparation work is that the printer 61 prints a bar code on a label paper located in the bidding platform 62, and the bar code is photographed and detected by the printing visual detection camera 63. If the bar code is printed incorrectly or the characters are unclear, the two vacuum chucks 46 are driven by the horizontal rod 11, the X-axis linear movement module 13, the first Z-axis linear movement module 41 or the second Z-axis linear movement module 51 to adsorb the error bar code, and then the error bar code is discarded in the waste box 64. If the bar code is qualified, the bar code is left on the bidding platform 62.

[0047] When the bar code needs to be taken, the cross bar 11, the X-axis linear motion module 13, the first Z-axis linear motion module 41 and the second Z-axis linear motion module 51 jointly drive the two vacuum suction cups 46 to approach the corresponding label removing platform 62. During the movement, the turnover motor 44 drives the turnover arm 45 to rotate to the horizontal direction of the printer 61, the suction nozzle of the vacuum suction cup 46 is downward, parallel to the X-axis direction, and located directly above the label removing platform 62. The first Z-axis linear motion module 41 and the second Z-axis linear motion module 51 respectively drive the vacuum suction cup 46 to descend and adsorb the bar code surface, and then ascend to remove the bar code, and the adhesive surface is downward.

[0048] The cross bar 11, the X-axis linear motion module 13, the first Z-axis linear motion module 41 and the second Z-axis linear motion module 51 jointly drive the two vacuum suction cups 46 to approach the conveying belt 21. During the movement, the two turnover motors 44 drive the two turnover arms 45 to turn over 180 degrees to the horizontal direction of the conveying belt 21, and the vacuum suction cup 46 drives the bar code to turn over to the adhesive surface upward, at this time, the two bar codes are parallel to the X-axis direction. Then the horizontal rotation motor 42 of the first bar code assembly 4 drives the rotating seat 43 to drive the turnover arm 45 to rotate 90 degrees in the horizontal plane, at this time, the bar code on the first bar code assembly 4 is parallel to the Y-axis direction.

[0049] Referring to Figure 10 and Figure 11 , the lifting assembly 7 includes a lifting servo motor 71 fixedly installed on the rack 1. A mounting frame 72 is fixedly connected to the moving end of the lifting servo motor 71, and the lifting servo motor 71 can drive the mounting frame 72 to move along the Y-axis direction, and also can adapt the mounting frame 72 to workpieces of different sizes. A lifting cylinder 73 is installed on the mounting frame 72, the side wall of the lifting cylinder 73 is fixedly connected with the side wall of the mounting frame 72, the cylinder shaft of the lifting cylinder 73 is downwardly arranged, a lifting plate 74 is fixedly installed on the cylinder shaft, a plurality of lifting suction cups 75 are installed on the bottom wall of the lifting plate 74, and the lifting suction cups 75 can adsorb the top wall of the battery string. In the embodiment, eight lifting suction cups 75 are arranged in an array on the bottom wall of the lifting plate 74, and are used to adsorb and lift the two battery strings at the edge.

[0050] The mounting frame 72 further installs a pressing cylinder 76, the pressing cylinder 76 is installed upside down on the mounting frame 72, and a pressing plate 77 is installed at the bottom end of the cylinder shaft of the pressing cylinder 76. The pressing plate 77 is used to press against the busbar on the battery string from above. The lifting assembly 7 further includes a busbar visual detection camera 78, which is installed on the side wall of the mounting frame 72 and is used to detect the accurate position of the incoming busbar.

[0051] Referring to Figure 3The label visual detection camera 14 is arranged on one side of the transfer assembly 2 close to the barcode printing assembly 6 in the rack 1, and is arranged obliquely upward and is aligned with the gap between the battery string and the battery plate 8 after the battery string is lifted up.

[0052] The working principle of the two barcode pasting operations is as follows: after the battery plate 8 is in place, the lifting servo motor 71 drives the lifting plate 74 to reach above the battery string, the lifting cylinder 73 drives the lifting plate 74 to drive the lifting suction cup 75 to descend until the suction nozzle of the lifting suction cup 75 is attached to the top wall of the battery string, the battery string is adsorbed, the lifting cylinder 73 drives the lifting suction cup 75 to rise and drive the end of the battery string to separate from the battery plate 8. At the same time, the busbar visual detection camera 78 takes a photo of the busbar for detection to obtain accurate position information and possible angle deviation.

[0053] The horizontal rod 11 and the X-axis linear motion module 13 drive the two vacuum suction cups 46 to approach the battery plate 8, the first Z-axis linear motion module 41 controls the height of the vacuum suction cup 46, so that the barcode parallel to the Y-axis direction is inserted below the battery plate 8, then the first Z-axis linear motion module 41 drives the vacuum suction cup 46 to rise, and the adhesive surface of the barcode is tightly attached to the bottom wall of the battery plate 8, after the pasting is completed, the vacuum suction cup 46 is released from the adsorption, and the first Z-axis linear motion module 41 drives the vacuum suction cup 46 to descend and separate from the battery plate 8.

[0054] The second Z-axis linear motion module 51 controls the height of the vacuum suction cup 46, so that the barcode parallel to the X-axis direction is inserted into the gap between the battery string and the battery plate 8, at this time, after the compensation servo motor 52 receives the accurate posture information of the busbar, the position of the vacuum suction cup 46 is fine-tuned together with the X-axis linear motion module 13, so that the barcode parallel to the X-axis direction is adapted to the position of the busbar. The second Z-axis linear motion module 51 drives the vacuum suction cup 46 to rise, and the vacuum suction cup 46 resists the adhesive surface of the barcode to the bottom wall of the battery string from below; at the same time, the abutting cylinder 76 drives the abutting plate 77 to descend and abut on the top wall of the battery string from above, and the two forces are superposed to paste the barcode on the bottom wall of the battery string. Then the vacuum suction cup 46 is released from the adsorption, the second Z-axis linear motion module 51 drives the vacuum suction cup 46 to descend, and the abutting cylinder 76 drives the abutting plate 77 to rise; the label visual detection camera 14 detects the barcode parallel to the X-axis, and after the detection is completed, the lifting suction cup 75 is released from the adsorption, and the battery string naturally falls onto the battery plate 8. The horizontal rod 11 and the X-axis linear motion module 13 drive the two vacuum suction cups 46 to reset.

[0055] The implementation principle of the barcode pasting mechanism of the photovoltaic cell in the embodiment of the application is as follows: The positioning principle of the battery plate 8 is as follows: the battery plate 8 is placed horizontally on the conveying belt 21 to enter the rack 1, and the two conveying belts 21 and the two sets of conveying wheels 22 jointly support the weight of the battery plate 8. After the battery plate 8 reaches the preset processing station, the homing jack cylinder 312 drives the homing wheel 314 to rise above the conveying belt 21, and the two homing rods 311 and the homing seat 321 also approach each other, and the four homing wheels 314 and the four homing blocks 323 approach the side wall of the battery plate 8 from all around to adjust and fix the position of the battery plate 8.

[0056] The working principle of the barcode preparation is as follows: the printer 61 prints a barcode on the bidding platform 62, and the printed visual detection camera 63 takes a photo of it. The two vacuum suction cups 46 have suction nozzles downward and parallel to the X-axis direction, adsorb the barcode surface, and then rise to peel off the barcode with the adhesive surface downward. Then the two vacuum suction cups 46 move close to the conveying belt 21, the turnover motor 44 drives the turnover arm 45 to turn over 180 degrees, and the vacuum suction cup 46 drives the barcode to turn over with the adhesive surface upward. Then the horizontal rotation motor 42 of the first barcode pasting assembly 4 drives the turnover arm 45 to rotate 90 degrees in the horizontal plane, and at this time the barcode on the first barcode pasting assembly 4 is parallel to the Y-axis direction.

[0057] The working principle of the two barcode pasting is as follows: after the battery plate 8 is in place, the lifting servo motor 71 drives the lifting plate 74 to reach above the battery string, the lifting cylinder 73 drives the lifting suction cup 75 to descend to adsorb the battery string, and then drives the lifting suction cup 75 to rise to lift the end of the battery string, and at the same time, the busbar visual detection camera 78 takes a photo of the busbar. The two vacuum suction cups 46 approach the battery plate 8, the first Z-axis linear motion module 41 controls the height of the vacuum suction cup 46, so that the barcode parallel to the Y-axis direction extends below the battery plate 8, and then the vacuum suction cup 46 rises to tightly press the adhesive surface of the barcode against the bottom wall of the battery plate 8.

[0058] The second Z-axis linear motion module 51 controls the height of the vacuum suction cup 46, so that the barcode parallel to the X-axis direction is inserted into the gap between the battery string and the battery plate 8, and at this time the compensation servo motor 52 and the X-axis linear motion module 13 jointly fine-tune the position of the vacuum suction cup 46. The vacuum suction cup 46 rises to press the adhesive surface of the barcode against the bottom wall of the battery string from below; at the same time, the pressing cylinder 76 drives the pressing plate 77 to descend and press against the top wall of the battery string from above, and the two forces are superimposed to paste the barcode on the bottom wall of the battery string. Then the labeling visual detection camera 14 detects the barcode parallel to the X-axis. The cross rod 11 and the X-axis linear motion module 13 drive the two vacuum suction cups 46 to reset.
