Description

TECHNICAL FIELD

[0001] The present application relates to the quality control of planar product film pasting, in particular, to a bubble driving squeegee device with direction control, especially suitable for satellite solar wing substrates. BACKGROUND

[0002] Some planar products are attached with a film layer, such as satellite solar wing substrates. When pasting the film, the product is prone to enter air, resulting in convexity and affecting the product quality. In order to ensure the appearance, flatness and bonding strength of the product, a squeegee is needed to drive the glue or bubbles in the process.

[0003] The traditional squeegee plate is flat, and in the process of driving bubbles, the bubbles are easy to leak from both sides or the bottom of the squeegee, and the driving direction of the bubbles cannot be controlled. Moreover, the squeegee generally used has a straight edge or a sharp end in the longitudinal cross-sectional shape of the squeegee track, which is easy to scratch the film, and a layer of superfine cloth or polytetrafluoroethylene release cloth is often needed during use.

[0004] Another common way to drive bubbles is to use a roller to drive, which has a large contact area and less damage to the film compared with the squeegee, but the one-time flat driving efficiency is low.

[0031] DETAILED DESCRIPTION

[0032] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0033] The present invention discloses a scraper device with direction-controlled bubble expulsion, which is used to ensure flatness when the product is film-laminated. It can prevent leakage from the sides and bottom when expelling bubbles, ensure the direction control of the bubble expulsion during the film-laminated process, avoid damage to the film surface by right-angle or pointed scraping rails, and at the same time achieve a certain inspection effect on flatness through hand feeling.

[0034] The present invention will be described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 4 As shown, a directionally controlled bubble-repelling scraper device according to the present invention comprises: a curved scraper 1, an extension 2, and a roller 3. The curved scraper 1 has a surface curvature of π, or an angle of 180 degrees. The curved scraper 1 can be made of stainless steel, carbon steel, or alloy steel, such as 3Cr13, 65Mn, or 55Si2Mn, ensuring rigidity and corrosion resistance. The curved scraper 1 and roller 3 work together to repel bubbles, and the two sequential repelling operations in one operation reduce the chance of bubbles escaping from beneath the scraper.

[0036] The left end and the right end of the arc-shaped squeegee 1 respectively extend out an extension part 2, and a roller 3 is installed between the two extension parts 2. The two extension parts 2 are both flat plates, and the two flat plate-shaped extension parts 2 are arranged in parallel to each other and extend along the tangential direction of the left end and the right end of the arc-shaped squeegee 1, as shown in Figure 2 .

[0037] The plate surface of the arc-shaped squeegee 1 is arc-shaped, the upper end of the arc-shaped squeegee 1 is a hand-holding end 101, the lower end of the arc-shaped squeegee 1 is a squeegee rail end 102, the hand-holding end 101 is thicker than the squeegee rail end 102, and the squeegee rail end 102 is in the same plane as the arc line of the product contact. The action line of the roller 3 is in the same plane as the squeegee rail arc line of the squeegee rail end 102. The longitudinal section of the squeegee rail end 102 is arc-shaped, as shown in Figure 3 . In a preferred embodiment, a handle is installed on the arc-shaped squeegee 1, and the handle can be used to control the movement direction of the squeegee during use.

[0038] The application will be described in more detail below.

[0039] The operator holds the hand-holding end 101 with one hand, and the arc-shaped squeegee 1 is in vertical contact with the product film surface and moves along the product film plane. The plate surface of the arc-shaped squeegee 1 is arc-shaped, which effectively prevents bubbles from leaking out from the sides of the squeegee, and as shown in Figure 4 , when the plate surface of the squeegee is arc-shaped, the squeegee generates a force directed towards the center of the circle when driving the bubbles, thereby preventing the bubbles from leaking out from the sides. Especially at the position on the arc-shaped squeegee 1 where the line connecting the left and right ends of the arc-shaped squeegee 1 forms a 45-degree angle, the force of the squeegee on the bubbles is the same in the x direction and the y direction, and the efficiency is the highest. The hand-holding end 101 of the arc-shaped squeegee 1 is thicker than the squeegee rail end 102, which can make the contact force more concentrated and make the operation more labor-saving. The profile of the longitudinal section of the squeegee rail end 102 of the arc-shaped squeegee 1 is arc-shaped, which avoids damage to the film during use.
