Description

Technical Field

[0001] The utility model relates to the technical field of silicon wafer encapsulation equipment, in particular to a substrate encapsulation device and substrate printing equipment using the same. Background Art

[0002] With the increasing global demand for renewable energy, the solar photovoltaic industry is experiencing rapid growth. During the texturing and printing processes for solar cells (silicon wafers), insulating ink or adhesive must be applied to the edges of the wafers before electroplating. This layer of insulating ink forms a protective insulation layer around the edges of the wafers, ensuring insulation performance during the electroplating process and improving reliability.

[0003] A type of substrate encapsulation device has emerged in the prior art. This type of substrate encapsulation device uses an encapsulation roller with a rotating ink layer to enable the rotating ink layer on the surface of the encapsulation roller to perform an encapsulation coating operation on the edge of the battery cell, thereby wrapping the edge of the battery cell to form an insulating ink layer, thereby improving the efficiency of coating to form the insulating ink layer.

[0004] However, this type of substrate encapsulation device has the following defects: first, the encapsulation roller is fixedly installed on the integral support seat, which makes it difficult to disassemble and assemble the encapsulation roller and the substrate encapsulation device, causing inconvenience when the encapsulation roller needs to be removed from the substrate encapsulation device for maintenance and repair, thereby affecting the encapsulation efficiency; secondly, when there is an offset and error in the horizontal position and angle of the encapsulation roller relative to the target substrate in the existing substrate encapsulation device, it is difficult to correct the position and angle of the encapsulation roller relative to the silicon wafer, thereby affecting the encapsulation accuracy; in addition, if the thickness of the ink layer formed by the encapsulation roller by wrapping the insulating oil film or insulating glue from the ink tank on the roller surface of the existing substrate encapsulation device is not uniform, it is difficult to adjust the uniformity of the thickness of the ink layer attached to the surface of the encapsulation roller, thereby affecting the thickness uniformity of the insulating ink layer formed by the encapsulation coating operation on the edge of the battery cell.

[0118] When the operator manually loosens the adjusting screw 723 and rotates the rotating handle at the end of the manual screw 71 to drive the nut moving part to move back and forth along the tilting lifting direction D on the transmission screw, the lifting moving part can be driven to move back and forth along the tilting lifting direction D relative to the slide base 72, thereby driving the ink scraper 8 to move closer to or away from the rubber-coated roller 9 along the tilting lifting direction D. After the ink scraper 8 is tilted and lifted into place, the adjusting screw 723 is tightened again until the adjusting screw 723 is locked to the base side plate 721, so that the relative position of the ink scraper 8 and the rubber-coated roller 9 remains fixed, thereby adjusting the gap between the bottom tip of the ink scraper 8 and the rubber-coated roller 9.

[0123] A central control device (not shown) and a camera device (not shown) are provided. The camera device is used to capture image data of the horizontal and angular position of the rubberized roller 9 relative to the target substrate by photographing the image data and transmit the image data to the central control device.
