Description

TECHNICAL FIELD

[0001] The application relates to a 3D curved glass straight side polishing clamp. BACKGROUND

[0002] 3D curved glass refers to glass with an arc edge on the side. Due to the arc edge on the side, the shape of the 3D curved glass is different from that of flat glass. The characteristics of the 3D curved glass meet the design requirements of 3C products, and the 3D curved glass has the characteristics of lightness, transparency, anti-fingerprint, anti-glare, hardness, scratch resistance, good weather resistance and the like. 3C product designs such as smart phones, smart watches, tablet computers, wearable smart products and instrument panels have successively appeared 3D products, which have clearly guided the development direction of 3D curved glass. The 3D curved glass for mobile phones needs to be polished on the straight side during processing, and a polishing clamp needs to be used for fixing during polishing.

[0003] The prior art with the publication number CN212444772U discloses a 3D curved glass straight side polishing clamp, which comprises a product fixing box for fixing the 3D curved glass, and fixing box limiting blocks arranged on both sides of the product fixing box. The fixing box limiting blocks have a radial edge portion in the form of a circular arc, which radially exceeds the side edges of the product fixing box. Since the radial edge portion radially exceeds the side edges of the product fixing box, the radial edge portion of the fixing box limiting block transitions to the straight side of the 3D curved glass during the rotation of the 3D curved glass. Since the radial edge portion is in the form of a circular arc and has a certain curvature, compared with the prior art in which the side edges of the rectangular jig box transition to the straight side of the 3D curved glass, the radial edge portion in the form of a circular arc can make the polishing brush transition to the 3D curved glass more smoothly, avoid the existence of polishing dead angles, and thus make the polishing of the straight side of the 3D curved glass more uniform, so as to ensure the uniformity of the overall brightness of the straight side of the 3D curved glass.

[0004] The polishing clamp described above stacks multiple curved glasses in the same fixing box. When polishing the curved glasses, only one straight side of the curved glass can be polished. Since the curved glass has multiple straight sides, the fixing position of the curved glass needs to be manually adjusted multiple times so that the straight side to be polished faces outward, which is inconvenient to operate and leads to low polishing efficiency. Moreover, the multiple curved glasses are in contact and stacked with each other. Since the curved glass has a recess arranged in the middle, the curved glass is easily damaged during clamping.

[0005] Therefore, it is desirable to provide a 3D curved glass straight side polishing clamp. CONTENT OF THE UTILITY MODEL
