Wrapping device

Abstract

The invention provides a wrapping device which is used for pressing four sides of the upper diaphragm which is affixed to the back of a mobile phone casing onto four side parts of the mobile phone casing, so as to wrap the mobile phone casing. The mobile phone casing is fixed on a positioning fixture. The wrapping device comprises a roller brush, a pressing mechanism and a drive mechanism which drives the roller brush and the pressing mechanism to be close to or away from the mobile phone casing. The roller brush and the pressing mechanism are connected with the drive mechanism. The pressing mechanism is arranged on one side of the roller brush. When one side part of the mobile phone casing is wrapped, the pressing mechanism is driven by the drive mechanism to first contact the mobile phone casing and press the mobile phone casing against the positioning fixture. The roller brush contacts the side part of the mobile phone casing to fold the side, which is corresponding to the side part, of the diaphragm and press the side against the side part to realize wrapping. According to the invention, automatic wrapping of the mobile phone casing is realized, and the wrapping efficiency and the fit precision are improved.

Description

technical field [0001] The invention relates to the field of automatic processing equipment, in particular to an edge wrapping device for processing mobile phone cases. Background technique [0002] With the development of electronic products in the direction of thinner and thinner, the mobile phone screen is required to be small and light, but also sensitive to touch and clear in display. Composed with LCD, from top to bottom, there are reflective film, light guide, lower polarizer, TFTLCD, upper polarizer, and a touch screen and cover plate will be covered on it. [0003] The existing mobile phone case has four sides connected in sequence and the back side connecting each side part. The four sides are folded and pressed respectively on the four sides of the mobile phone case. At present, it is generally done manually. The manual operation is time-consuming and inefficient, and it is impossible to ensure that the film covers the mobile phone case The accuracy of the edge ...

Problems solved by technology

[0004] Based on this, it is necessary to manually press and paste the four sides of the diaphragm on the back of the mobile phone case to the four sides of the mobile phone case, which is labor-intensive, inefficient, and low in precision To solve the problem, provide a hemming device that can automatically press the four sides of the diaphragm that has been pasted on the back of the mobile phone case to the four sides of the mobile phone case, which makes the four sides of the diaphragm The two sides can be accurately pressed on the four sides of the mobile phone case respectively, and it will not pollute the mobile phone case and diaphragm
