Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic devices, in particular to a novel flux coating structure and coating device. BACKGROUND

[0002] Currently, in addition to pursuing higher power and better performance of photovoltaic modules, the appearance of the modules is also increasingly high. Among them, the black bus bar has been favored by many customers due to its all-black appearance. In the process of manufacturing black modules in module factories, a black coating is coated on the outer side of the bus bar, and a tin coating is coated on the inner side of the bus bar, to ensure that the appearance of the module is all black.

[0003] The existing flux coating structure is composed of a base, a sponge shell, a sponge, a bus bar reel and a flux sprayer. The sponge shell is installed on the base, and a flux dripping hole is formed at the top of the sponge shell. The flux sprayed by the flux sprayer drips into the sponge in the sponge shell through the flux dripping hole on the sponge shell, so that the sponge is in a wet state. The bus bar reel is arranged on one side of the base. The bus bar enters the sponge from one side of the sponge shell and passes out from the other side of the sponge shell. In this way, when the bus bar is pulled, the upper and lower surfaces of the bus bar are coated with flux.

[0004] After the bus bar is soaked in the flux, it needs to be welded to the front surface of the cell. The black bus bar has a black coating on one side and a tin coating on the other side. After the black bus bar is soaked in the flux and laminated in the module, bubbles will be generated on the surface of the black coating, affecting the welding effect. SUMMARY

[0005] (I) The problem to be solved by the present application is that in the existing flux coating structure, the black bus bar enters the sponge from one side of the sponge shell and passes out from the other side of the sponge shell. In this way, when the black bus bar is pulled, the upper and lower surfaces of the black bus bar are coated with flux. After the black bus bar is laminated in the module, bubbles will be generated on the surface of the black coating.

When mounting the supporting disc 401, first insert the two bolts 407 from the back into the through holes on the mounting plate 2, then align the circular hole on the supporting disc 401 with the bolts 407, push the supporting disc 401 until the supporting disc 401 is close to the front surface of the mounting plate 2, then put the nuts into the mounting holes 406 and screw them into the bolts 407, and then continue to screw the nuts, the nuts rotate while driving the supporting disc 401 to approach the mounting plate 2, until the supporting disc 401 is tightly attached to the mounting plate 2.

[0047] According to one embodiment of the present application, in the present embodiment, the cross section of the supporting disc 401 is a sector, the supporting disc 401 supports the upper half of the coating belt 402, and the inner side of the coating belt 402 is attached to the arc surface of the supporting disc 401.

[0049] According to one embodiment of the present application, as shown in Figure 5 The profile support mechanism further comprises a limiting guide wheel 404 mounted on the mounting plate 2, the limiting guide wheel 404 is located in the lower half of the coating belt 402, the outer side of the limiting guide wheel 404 is engaged with the inner side of the coating belt 402, and the height of the limiting guide wheel 404 is adjustable. Since the height of the support disc 401 is constant, the tightness of the coating belt 402 can be adjusted by adjusting the height of the limiting guide wheel 404.

Since the outer side of the third rotating sleeve is engaged with the inner side of the coating belt 402 and the third rotating sleeve can also rotate relative to the third inner shaft, when the coating belt 402 rotates, it will drive the third rotating sleeve to rotate. When the height of the limiting guide wheel 404 needs to be adjusted, the third nut is unscrewed, then the height is manually adjusted, the back of the third inner shaft is tightly attached to the mounting plate 2, and then the third nut is screwed onto the third screw rod.

The flattening mechanism 6 comprises an upper flattening roller 601 and a lower flattening roller 602 horizontally mounted on the front surface of the mounting plate 2, the upper flattening roller 601 and the lower flattening roller 602 are of the same specification and can rotate relative to the mounting plate 2, and the height of the upper flattening roller 601 and the lower flattening roller 602 can be adjusted to adjust the width of the gap between the upper flattening roller 601 and the lower flattening roller 602.

In particular, the length of the second rotating sleeve is less than the length of the second inner shaft, the distance between the back of the second rotating sleeve and the mounting plate 2 is greater than the distance between the back of the second inner shaft and the mounting plate 2, so that when the upper leveling roller 601 and the lower leveling roller 602 are installed, the second inner shaft is tightly attached to the front of the mounting plate 2, but the back of the second rotating sleeve is not in contact with the front of the mounting plate 2, and does not hinder the normal rotation of the second rotating sleeve.

[0056] According to one embodiment of the present application, as shown in Figure 4 and Figure 6 As shown, the flux injection mechanism comprises a flux delivery pump 8 mounted on the mounting plate 2, the outlet of the flux delivery pump 8 is connected with an outlet pipe 802, the inlet of the flux delivery pump 8 is provided with an inlet pipe 801, one end of the outlet pipe 802 penetrates through the second vertical slot hole 203 in the mounting plate 2 and is then inserted into the soaking pool 3, and the outlet of the outlet pipe 802 is connected to the partition plate 303, so that the flux in the outlet pipe 802 will flow into the lower soaking box 301 instead of flowing into the upper housing 302 above the partition plate 303, and the inlet pipe 801 is inserted into the storage tank for storing the flux.

[0057] A novel flux coating device comprises the above-mentioned flux coating structure, as shown in Figure 1 As shown, the coating device further comprises a mounting seat 5 arranged on the left side of the coating structure, the right side of the mounting seat 5 is provided with a drying device and a pulling mechanism (not shown in the figure), a black busbar reel 501 is mounted on the mounting seat 5, and the black busbar is wound in the black busbar reel 501. The drying device is used for drying the black busbar coated with flux, and the pulling mechanism is used for pulling the black busbar. The black busbar reel 501, the pulling mechanism and the drying device are all existing devices, the pulling mechanism can be a movable mechanical arm, the mechanical arm is mounted on an electric sliding rail and is driven to move by the electric sliding rail, and the mechanical arm clamps the black busbar. The pulling mechanism can also be other mechanisms that can drive the black busbar to move, such as a plurality of conveying clamping rollers. The drying device is provided with slot holes on both sides for the black busbar to enter and exit.

[0058] In combination with Figures 1 to 7The working principle of the coating device is described as follows: the black bus bar is wound on the black bus bar reel 501, then the black bus bar reel 501 is installed on the mounting seat 5, then one end of the black bus bar is pulled, so that the black bus bar is attached to the lower surface of the tension adjusting mechanism 7, then the black bus bar is inserted between the upper leveling roller 601 and the lower leveling roller 602, then the black bus bar is pulled horizontally to the right side, at this time, the lower surface of the black bus bar is attached to the outer side of the coating belt 402, then the black bus bar is continuously pulled, and the black bus bar is clamped by the movable mechanical arm after passing through the drying device. At this time, the height of the upper leveling roller 601 is adjusted to adjust the width of the gap between the upper leveling roller 601 and the lower leveling roller 602, so that the upper leveling roller 601 and the lower leveling roller 602 can lightly press the black bus bar, thereby preventing the black bus bar from being twisted. Then, the position of the first rotating sleeve 701 is adjusted to adjust the tension of the black bus bar, so that the black bus bar is not loose or too tight when moving. Further, the two motors 405 drive the two driving guide rollers 403 to rotate, and drive the coating belt 402 to rotate from both sides of the coating belt 402. With the rotation of the coating belt 402, the coating belt 402 entering the lower soaking box 301 is soaked in the flux, so that the outer side of the coating belt 402 is wet. With the continuous rotation of the coating belt 402, the outer side of the entire coating belt 402 is wet, and the lower surface of the black bus bar is in contact with the outer side of the coating belt 402. In this way, with the movement of the black bus bar, the flux on the outer side of the coating belt 402 is coated on the lower surface of the black bus bar.

[0059] The coating structure can uniformly coat the flux on the inner side of the black bus bar, and achieve single-sided coating. Compared with the traditional double-sided coating method, the black coating surface of the black bus bar does not have flux, so that no bubbles are generated on the black coating surface after laminating the assembly, thereby ensuring good appearance and not affecting the welding effect. Compared with the traditional double-sided coating of flux, the coating structure is single-sided coating, which saves a large amount of flux and reduces the cost.
