Apparatus for applying collagen to local portion of surface of product

Abstract

The invention discloses an apparatus for applying collagen to the local portion of the surface of a product. The apparatus includes an upper layer, a lower layer, steel sheets, collagen deviation paper and collagen, and a positioning plate is fixed on the lower layer through a support plate; the steel sheets are installed on the upper layer; the collagen deviation paper is installed on the positioning plate, and the collagen is arranged on the collagen deviation paper; and the positioning plate is also provided with an edge positioning structure for the steel sheets and the collagen deviation paper. The apparatus for applying collagen to the local portion of the surface of a product is characterized in that the steel sheets and the collagen deviation paper can be simultaneously positioned by the positioning plate, a median error caused by an indirect positioning mode of a positioning hole and a positioning pin is avoided, and the stability of the relative dimension between the steel sheets and the collagen is maintained; and the collagen is applied to the product positioned on the steel sheets through the relative movement of the upper layer and the lower layer, and the drag of a transmission device to the collagen deviation paper can realize the continuous application of the collagen.

Description

technical field [0001] The invention relates to a device for locally pasting collagen on the surface of a product. Background technique [0002] As the process complexity of products increases, some products need to be partially pasted with collagen on the surface. The existing devices for partially pasting collagen have the following two structures: [0003] One is a single film bonding structure, the upper layer of the device is equipped with a steel sheet, the lower layer of the device is used to locate the position of the collagen, and the collagen is attached to the product on the steel sheet through the relative movement of the upper layer and the lower layer of the device; this device structure Simple, but only one piece of film can be attached at a time. The efficiency of collagen bonding is low, and the collagen is placed in the positioning position manually every time, so the quality of bonding is not easy to guarantee. [0004] The other is a multi-film continuou...

Problems solved by technology

[0003] One is a single film bonding structure, the upper layer of the device is equipped with a steel sheet, the lower layer of the device is used to locate the position of the collagen, and the collagen is attached to the product on the steel sheet through the relative movement of the upper layer and the lower layer of the device; this device structure Simple, but only one piece of film can be attached at a time, the efficiency of collagen lamination is low, and the collagen is placed in the positioning position manually every time, the quality of lamination is not easy to guarantee

[0004] The other is a multi-film continuous lamination structure. The upper layer of the device is equipped with steel sheets, and the lower layer of the device is equipped with positioning pins. There are positioning holes, the collagen is positioned through the cooperation of the positioning pin and the positioning hole, the relative movement of the upper layer and the lower layer of the device sticks the collagen to the product on the steel sheet, and the driving device drags the collagen away from the paper to realize the continuous sticking of the collagen However, in this structure, there will be errors between the collagen and the positioning holes, and there will be errors between the steel sheet and the positioning holes. The combination of these two errors will affect the quality of the fit, and due to continuous production, Errors will accumulate and eventually lead to poor fit quality
