Background

Currently, one of the leading edge solar photovoltaic technologies is to replace the traditional silver paste printing with copper interconnection technology. Another major advantage of copper interconnect technology over traditional silver paste printing technology, in addition to cost, is that copper interconnect can be thinned. One of the core technologies for fine line formation is a pattern transfer technology of wet film photoresist. In the copper interconnection battery technology, wet film photoresist is used for printing, developing and electroplating to manufacture copper grid lines of battery pieces, so that the traditional silver paste printing technology is replaced.

The current copper interconnect technology process flow is as follows: copper plating seed layer- & gt coating (front or back) & gt drying- & gt coating (back or front) & gt drying- & gt printing- & gt developing- & gt electroplating.

The printing process refers to exposing the battery piece coated with the photoresist to enable the photosensitive material of the exposed area to be denatured, and only the photosensitive material with a specific shape is left on the surface of the battery piece under the corrosion action of the matched chemical reagent. When the conventional printing equipment is used for carrying out the graphic exposure operation of the battery piece, deviation easily occurs in graphic transfer, and the subsequent graphic quality of the electroplated copper grid line is affected.

Currently, one of the leading edge solar photovoltaic technologies is to replace the traditional silver paste printing with copper interconnection technology. The current copper interconnect technology process flow is as follows: copper plating seed layer- & gt coating (front or back) & gt drying- & gt coating (back or front) & gt drying- & gt printing- & gt developing- & gt electroplating.

The printing process refers to exposing the battery piece 200 coated with the photoresist to denature the photosensitive material in the exposed area, and then corroding the battery piece 200 by using a chemical reagent matched with the denatured photosensitive material in a subsequent developing process, so that only the photosensitive material with a specific shape is left on the surface of the battery piece 200. Then, in the subsequent electroplating process, electroplating copper is carried out in the groove formed by the photosensitive material with the specific shape, so as to form the copper grid line.

In exposing the battery cell 200 using the existing printing apparatus, referring to fig. 1, the battery cell 200 is placed on a conveyor belt of a belt conveyor 101, and then the battery cell 200 is sequentially passed under a laser 102 by using the conveyor belt, so that exposure of a specific area is completed, and an exposure area similar to a linear one is formed.

However, the inventors found that after printing of the battery sheet 200 using the existing printing apparatus, the width and depth of the linear exposure region formed are uneven, resulting in uneven grooves formed after subsequent development, and adhesion of residual glue is easy to occur in the grooves, and further copper gate lines with uneven thickness are formed after the subsequent copper electroplating process, and gate breakage is easy to occur.

The inventors analyze the cause of uneven thickness of the gate line and broken gate, consider that: during the process of conveying the battery piece 200, the belt conveyor 101 deforms due to the gravity of the battery piece 200, so that the height distance between the battery piece 200 and the laser 102 changes. Because the battery pieces 200 are generally randomly placed at different positions of the belt conveyor 101, the deformation capability of the conveyor belt at the different positions is different, so that a larger error exists in the height distance between the battery pieces 200 at the different positions and the laser 102, and further, the light spot area and the illumination intensity irradiated on the upper surface of the battery pieces 200 are changed, and further, grooves with uneven width and depth are formed after subsequent development, so that the quality of the subsequent electroplated copper grid line is affected.

The difference in deformability means that, for example, during the continuous conveyance of the battery pieces 200 by the belt conveyor 101, the greater the number of times that the battery pieces 200 are carried by the conveyor belt of some portions, the more severely the conveyor belt of these portions is deformed, and the greater the height distance between the battery pieces 200 and the laser 102 that are subsequently placed at the conveyor belt of these portions.

The inventor tries to place the battery 200 by using a hard and non-deformable carrier plate in order to improve the problem that the height distance between the battery 200 and the laser 102 is changed, so that the height distance between the battery 200 placed on the carrier plate and the laser 102 is kept consistent.

However, the inventors have found that generally rigid, carrier plates are not easily positioned, and that the battery plate 200 placed on the carrier plate is easily biased, resulting in an offset exposure area after exposure.

Thus, the inventors have provided a stage 11, such as a glass stage, that is light transmissive for ease of positioning. Then, the battery piece 200 placed on the slide holder 11 can be photographed by using a photographing device, and whether the placement direction of the battery piece 200 in the photographed image is a preset printing direction or not is analyzed to perform positioning.

However, the inventors further found that when printing the upper surface of the battery plate 200 placed on the transparent stage 11, referring to fig. 2, a portion of the light does not perpendicularly irradiate the transparent stage 11. The light is refracted from the first surface 111 of the stage 11 for carrying the battery 200 into the stage 11, then reflected at the second surface 112 of the stage 11, and then emitted from the first surface 111 to irradiate the lower surface of the battery 200.

Since the photoresist at the upper and lower surfaces of the battery cell 200 is very sensitive to white light, the white light irradiated from the first surface 111 at the lower surface of the battery cell 200 during exposure of the upper surface of the battery cell 200 may accidentally expose the nonspecific exposure region at the lower surface of the battery cell 200, damaging the patterning of the lower surface of the battery cell 200.

Therefore, in order to avoid accidental exposure of the non-preset exposure area of the battery piece 200 by the transparent stage 11, the inventor sets the yellow light film 113 at the first surface 111 of the transparent stage 11, so that the light emitted from the first surface 111 is all yellow light, thereby reducing the probability of breaking the pattern of the lower surface of the battery piece 200 and improving the printing quality.

Accordingly, the present embodiment provides a printing system 1 including a printing apparatus 10 and a feed mechanism 20.

Referring to fig. 3, the printing apparatus 10 includes a light-transmitting stage 11, a laser printer 12, and a conveying mechanism 13. The stage 11 has opposite first and second surfaces 111, 112, the first surface 111 being provided with a yellow light film 113. The laser printer 12 is disposed above the first surface 111, and the laser printer 12 is spaced apart from the first surface 111 by a predetermined distance to irradiate the battery cell 200 disposed on the first surface 111. The conveying mechanism 13 is used for conveying the stage 11 to approach or separate from the lower side of the laser printer 12 along the preset direction D1.

Further, the printing device 10 also includes a positioning mechanism 14. The positioning mechanism 14 includes a detector 141 and an adjustor 142. The detector 141 includes a camera 1411 and a light supplement lamp 1412, the camera 1411 being disposed above the first surface 111, the light supplement lamp 1412 being disposed below the second surface 112. The adjuster 142 is in signal connection with the camera 1411, and the adjuster 142 is connected with the stage 11 to adjust the angle of the stage 11, so that the battery piece 200 on the first surface 111 is placed along the preset direction D1. A schematic diagram of the preset direction D1 is shown in fig. 4.

Placing the battery piece 200 along the preset direction D1 means that the extending direction of the exposed area similar to the linearity after exposure is consistent with the required printing direction along the lower part close to and far from the laser printer 12 under the conveying action of the conveying mechanism 13 by the battery piece 200.

For example, with continued reference to fig. 4, when the grid grooves 201 extending along the length direction of the battery plate 200 need to be formed on the battery plate 200, the preset direction D1 is consistent with the length direction of the battery plate 200.

Alternatively, when it is necessary to form the gate groove 201 extending in the width direction thereof on the battery piece 200, the preset direction D1 coincides with the width direction of the battery piece 200, and at this time, the conveying direction of the conveying mechanism 13 coincides with the width direction of the battery piece 200, and the laser printer 12 is located above the moving direction of the conveying mechanism 13.

Referring to fig. 5, the feeding mechanism 20 includes a first conveyor 21 and a first transfer machine 22. The first conveyor 21 is disposed at the front end of the printing device 10, and is used for conveying the battery piece 200 to be printed at the front end of the printing device 10. The first transfer machine 22 is disposed between the first conveyor 21 and the printing device 10, and is configured to transfer the battery piece 200 on the first conveyor 21 to the stage 11.

Further, with continued reference to fig. 5, the printing system 1 may also be provided with a discharge mechanism 30. The outfeed mechanism 30 includes a second conveyor 31 and a second transport 32. The second transfer machine 32 is disposed between the second conveyor 31 and the printing device 10, and is configured to transfer the battery piece 200 on the stage 11 to the second conveyor 31. The second conveyor 31 is disposed at the rear end of the printing device 10, and is used for conveying the printed battery piece 200 at the rear end of the printing device 10.

The printing apparatus 10, the feeding mechanism 20, and the discharging mechanism 30 in the printing system 1 are described in further detail below with reference to the accompanying drawings, respectively.

The printing apparatus 10 includes a light-transmissive stage 11. The slide holder 11 is used for carrying the battery piece 200, and the battery piece 200 placed on the slide holder 11 is printed with a preset pattern under the conveying action of the conveying mechanism 13.

The specific type of the stage 11 is not limited, and related personnel can select the stage 11 with good light transmittance and deformation resistance according to the requirements.

In one possible embodiment, stage 11 may be a glass stage structure. The glass table structure has high light transmittance and high hardness.

Further, the stage 11 may be provided in a diffuse reflective glass stage structure. The diffuse reflection glass table structure has good light transmittance and deformation resistance, and can also reduce the reflectivity of light, further reduce the light passing out of the first surface and reduce the light receiving rate of the lower surface of the battery piece 200.

Or, the slide holder 11 can be set to be a transparent acrylic plate, so that the thickness of the acrylic plate can be properly increased, and the deformation resistance of the acrylic plate is improved.

Further, a yellow light film 113 may be disposed on the light-transmitting second surface 112, so that the light filtering performance can be further enhanced.

The laser printer 12 is used for emitting laser to expose photoresist on the surface of the battery piece 200, so that the photoresist in the exposed area is denatured, and the denatured photoresist is removed later to form the grid line groove 201.

In one possible embodiment, laser printer 12 includes a plurality of laser lights. The plurality of laser lamps are spaced apart to simultaneously expose the surface of the passing battery cell 200 to form a plurality of exposed areas so as to simultaneously form a plurality of gate line grooves 201 later.

The conveying mechanism 13 is used for conveying the stage 11 to reciprocate along a preset direction D1 so that the battery piece 200 passing under the laser printer 12 forms an exposure area extending along the preset direction D1.

The specific arrangement of the conveying mechanism 13 is not limited in this application, and the relevant person may make a corresponding choice as required.

In one possible embodiment, the transport mechanism 13 includes a rail 131 and a slider 132 slidably coupled to the rail 131. The stage 11 can reciprocate along the extending direction of the guide rail 131 in synchronization with the slider 132. The extending direction of the guide rail 131 coincides with the preset direction D1.

The positioning mechanism 14 is used for positioning the battery piece 200 placed on the carrying platform 11, and preventing the battery piece from being transported by the transporting mechanism 13, and the exposure area formed below the laser printer 12 is shifted from the exposure area to be formed.

In an example, the positioning mechanism 14 includes a detector 141 and an adjustor 142. The camera 1411 in the detector 141 is used to capture the battery plate 200 at the first surface 111 of the stage 11, and the light-compensating lamp 1412 is used to illuminate the second surface 112 of the stage 11 to obtain a bright-dark image with a clear boundary. The adjuster 142 is communicatively connected to the camera 1411, so that the position of the stage 11 can be adjusted to place the battery 200 along the predetermined direction D1.

Further, the light supplement lamp 1412 may select a yellow light lamp.

The camera 1411 and the laser printer 12 are both positioned above the first surface 111 to illuminate the battery cell 200 placed at the first surface 111. The specific positions of the camera 1411 and the laser printer 12 are not limited, and related personnel can make corresponding selections as required under the condition that the battery piece 200 before being printed by the laser printer 12 needs to be photographed and positioned by the camera 1411.

In one possible embodiment, the camera 1411 and the laser printer 12 are disposed at a distance along the movement direction of the conveying mechanism 13, so that the battery piece 200 placed on the stage 11 first passes through the photographing location of the camera 1411, then adjusts the placement direction of the battery piece 200, and then passes under the laser printer 12 through the conveying mechanism 13.

The present application is not limited as to how the adjustor 142 is communicatively coupled to the camera 1411, and in some possible embodiments, the adjustor 142 may be communicatively coupled to the camera 1411 via a wired connection or a wireless connection.

The particular arrangement of the regulator 142 is not limited in this application, and the relevant person may make a corresponding choice as desired.

In one possible embodiment, the adjuster 142 includes a rotational shaft 1421. One end of the rotation shaft 1421 is fixedly connected to the stage 11, and the other end of the rotation shaft 1421 is provided to be connected to a rotation motor 1422.

The rotary motor 1422 can drive the rotary shaft 1421 to rotate, and further drive the slide holder 11 to rotate.

Further, the rotation axis 1421 may be coupled to the second surface 112 of the stage 11.

Alternatively, the adjuster 142 may include a fixed table and a screw. Screw holes are formed in the fixing table and the slide table 11, and screws penetrate through the screw holes simultaneously. When the angle of the slide holder 11 needs to be adjusted, the screw can be unscrewed, then the slide holder 11 is rotated for a certain angle relative to the fixed table, and then the screw is unscrewed, so that the rotated slide holder 11 is fixed on the fixed table.

Further, the tip of the screw does not exceed the first surface 111 of the stage 11.

Further, in order to facilitate the setting of the regulator 142, a base 133 may be provided in the conveying mechanism 13. The base 133 is fixedly connected with the slider 132, and then the slide holder 11 is rotatably connected with the base 133 through a rotation shaft 1421.

Further, the light-compensating lamp 1412 may be disposed around the edge of the base 133, and the edge of the base 133 does not exceed the edge of the battery plate 200, so that the battery plate 200 can block part of the light-compensating lamp 1412, so as to facilitate the camera 1411 to shoot and obtain a bright-dark image with a distinct interface.

Further, a mounting groove may be provided in the base 133 to facilitate mounting of the rotary electric machine 1422.

The specific arrangement of the first conveyor 21, the first transfer conveyor 22, the second conveyor 31, and the second transfer conveyor 32 is not limited in this application, and in one possible embodiment, the first conveyor 21 and the second conveyor 31 are both belt conveyors. The first transfer machine 22 and the second transfer machine 32 each include a suction cup, and the suction cup is used to suck the battery piece 200 for transferring the battery piece 200.

Further, the first transfer machine 22 also includes a screw and a guide rod. Both ends of the screw rod and the cutter bar are respectively positioned above the first conveyor 21 and the slide holder 11, and the sucker reciprocates along the axial direction of the screw rod. The second transporter 32 may be provided in the same manner as the first transporter 22.

The working principle of the printing device 10 provided in the embodiment of the present application is as follows:

the slide holder 11 is always spaced from the laser printer 12 by a preset distance, so that each battery piece 200 placed on the slide holder 11 for printing maintains a certain height distance from the laser printer 12, and a uniform exposure area is formed.

In addition, the camera 1411 is disposed above the first surface 111 of the transparent stage 11, and the light-compensating lamp 1412 is disposed below the second surface 112 of the stage 11, so that the second surface 112 of the stage 11 can be irradiated by the light-compensating lamp 1412, and when the battery piece 200 is placed on the first surface 111 of the stage 11, the battery piece 200 does not transmit light and blocks part of the light from the light-compensating lamp 1412 due to the light transmittance of the stage 11. Therefore, when the camera 1411 shoots the first surface 111, a bright-dark image with a clear boundary can be obtained, and whether the placement position of the battery piece 200 on the stage 11 is shifted can be clearly determined. And the adjuster 142 is in communication connection with the camera 1411, and when the placement position of the battery piece 200 is shifted, the position of the slide holder 11 can be adjusted by the adjuster 142, so that the battery piece 200 is placed along the preset direction D1.

Since the first surface 111 of the stage 11 is provided with the yellow light film 113, the light passing out of the first surface 111 is yellow light, and the effect of the yellow light on the patterning effect at the lower surface of the battery piece 200 is less, so that the printing quality of the battery piece 200 can be improved.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art.
