Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Example one

As shown in fig. 1, the present embodiment provides a flat bar code attaching method for attaching a bar code 100 to a product, wherein for convenience of description and understanding, the side of the bar code 100 with glue is referred to as a reverse side, and the side with information is referred to as a front side, and the front side faces upward and the reverse side faces downward during the transmission of the bar code 100. In this embodiment, the product may be a photovoltaic module, or may be another product having a plane, and for convenience of description, the photovoltaic module is taken as an example for expanding description, and the method for attaching a planar barcode includes the following steps:

the method comprises the following steps: the photovoltaic module is positioned at a first preset position through the conveying module 1.

Step two: the feeding assembly 2, which is communicatively coupled to the control system, receives and prints the bar code 100 according to the control system transmissions. The feeding assembly 2 may be a printer, the printing principle of which is well known to those skilled in the art and thus will not be described herein.

Step three: after the bar code 100 is printed and the gum is torn off, the gum flows out to the auxiliary thrust assembly 3 through the printed outlet end.

Step four: the auxiliary pushing unit 3 provides an auxiliary pushing force for forward movement, and the blowing unit 4 blows a uniform and stable gas to the bar code 100, so that the bar code 100 moves to the moving unit 5 while maintaining a planar state.

Step five: the bar code 100 moves to a second preset position on the moving assembly 5, and positioning processing of the position before the bar code 100 is carried is achieved.

Step six: the carrying assembly 6 absorbs the bar code 100, adjusts the preset pasting angle of the bar code 100, carries the bar code 100 to a first preset position, and pastes the bar code 100 to the photovoltaic assembly.

Through the method, in the whole process, especially between the feeding assembly 2 and the moving assembly 5, the bar code 100 is kept in a plane state in a blowing mode, the bar code 100 kept in the plane state can be accurately moved to the preset position, the problem of winding adhesion cannot occur, and the attaching efficiency and the yield of the bar code 100 are improved.

When the bar code 100 moves from the auxiliary thrust unit 3 to a position between the moving units 5, there may occur a problem of downward bending in that, in order for the bar code 100 to smoothly pass through a gap between the auxiliary thrust unit 3 and the moving unit 5 and move onto the moving unit 5, a uniform and stable gas is blown out to the bar code 100 not contacting the moving unit 5 in step four, forming a stable pushing power, and the opposite surface of the end of the auxiliary bar code 100 contacts the moving unit 5. Specifically, the gas is blown from below to above, and the end of the auxiliary barcode 100 moves onto the moving assembly 5 in a floating state. This method can provide a certain buoyancy to the bar code 100 to prevent the bar code 100 from bending downward. Wherein the blowing mode can adapt to the narrow gap between the auxiliary thrust assembly 3 and the moving assembly 5. Of course, in other embodiments of the present embodiment, the air flow direction may flow along the moving direction of the barcode 100, or the air flow direction may flow along the moving direction of the barcode 100 and be slightly inclined upward.

In order to solve the above problem, in the present embodiment, specifically, in the fourth step, a uniform and stable gas is blown out from the barcode 100 that has contacted the moving assembly 5 to form a stable pushing power to assist the barcode 100 to completely move onto the moving assembly 5. Specifically, in step four, when the tail of the barcode 100 does not leave the auxiliary pushing assembly 3, the gas is blown from bottom to top to provide a supporting force for the barcode 100, so as to avoid collapsing downward, so that the barcode 100 is entirely planar, and the auxiliary barcode 100 is accurately moved onto the moving assembly 5. The above method helps to keep the bar code 100 flat on the moving assembly 5.

When the end of the bar code 100 contacts the moving assembly 5, the bar code 100 is affected by the length of the gap between the moving assembly 5 and the auxiliary pushing assembly 3, the length and the thickness of the gap, and the glue, and sometimes the bar code 100 bulges upwards or collapses downwards, depending on the field. In order to adapt to the different deformations of the barcode 100, in the present embodiment, in step four, when the tail of the barcode 100 does not leave the auxiliary thrust assembly 3, the first gas is blown from bottom to top, the second gas is blown from top to bottom, and the gas flow rates of the first gas and the second gas are adjusted, so that the barcode 100 is integrally planar, and the middle part of the auxiliary barcode 100 smoothly moves to the moving assembly 5. In the present method, the barcode 100 may be kept planar according to the resultant force of the first gas and the second gas. When the barcode 100 is collapsed downward, the flow rate of the first gas is greater than that of the second gas, when the barcode 100 is raised upward, the flow rate of the first gas is less than that of the second gas, and the flow rates and flow rates of the first gas and the second gas are adjusted by a throttle valve.

In order to prevent the bar code 100 from bending downward, in step four, after the tail of the bar code 100 leaves the auxiliary pushing assembly 3, since the front end of the bar code 100 is already adhered to the moving assembly 5, the bar code 100 continues to move forward under the action of the moving assembly 5, and at this time, air is blown from bottom to top to prevent the middle or tail of the bar code 100 from bending downward, so that the middle and/or tail of the bar code 100 moves onto the moving assembly 5 in a floating state. In other embodiments, after the tail of the barcode 100 leaves the auxiliary thrust assembly 3, the air may be blown from top to bottom, so as to prevent the barcode 100 from being tilted. Of course, the shape of the gas in the above embodiment can be determined according to the shape of the gas outlet nozzle of the gas blowing assembly 4, and since the bar code 100 is transported forward along the length direction thereof, the shape of the gas outlet nozzle is preferably a strip, the blown gas forms an air curtain, the width of the air curtain is greater than or equal to the width of the bar code 100, and the transporting direction of the bar code 100 is perpendicular to the plane of the air curtain.

In order to improve the adhesion effect of the bar code 100, in the present embodiment, after the sixth step, the rolling process is performed on the pasted bar code 100. Specifically, after step six, suction pad 636, which has released bar code 100, is raised, crimping roller 643 is lowered to be lower than suction pad 636, and bar code 100 is subjected to a rolling process. In this embodiment, with the above method, the lifting mechanism of the suction cup 636 and the lifting mechanism of the pressure welding roller 643 are arranged in a linkage manner, wherein the lifting mechanism of the pressure welding roller 643 is arranged at the output end of the lifting mechanism of the suction cup 636, and this arrangement greatly improves the pressure welding efficiency after the bar code 100 is well adhered, thereby improving the adhesion efficiency of the whole bar code 100.
