[0017] Example like Figures 1-4 As shown in the figure, an embodiment of the present invention provides an automatic bonding device for mobile phone accessories, including a base 1, a hollow rotating stage 2 installed in the base 1, a frustum 3 installed on the turntable of the hollow rotating stage 2, a positioning fixture 4 fixed on the frustum 3, a Y-axis linear module 5 installed on the table surface of the base 1, a gantry 6 installed on the slide of the Y-axis linear module 5, an X-axis linear module 7 installed on the gantry 6, a fixing plate 8 installed on the slide of the X-axis linear module 7, a rotary cylinder 9 and a machine vision camera 10 respectively installed at both ends of the fixing plate 8, and a pad 11 installed on the turntable of the rotary cylinder 9. The device is equipped with a sliding table cylinder 12 around its perimeter, and a lifting cylinder 13 is installed at the output end of the sliding table cylinder 12. The evenly distributed positioning fixture 4 is controlled by the hollow rotary table 2 to rotate according to a preset rhythm, realizing intermittent multi-process synchronous processing. Through the coordinated control of the linear module, rotary cylinder 9, machine vision camera 10, sliding table cylinder 12, lifting cylinder 13 and vacuum nozzle 14, a fully automatic closed loop of multi-auxiliary material identification, positioning, holding, mounting and changing is realized, eliminating the intermittent time of manual material handling. It can cover the co-line production of mainstream auxiliary materials such as LCD foam and motor foam, which can greatly improve production efficiency. The output end of the lifting cylinder 13 is equipped with a vacuum nozzle 14.

[0018] like Figure 1 As shown, in some embodiments, the platform of the base 1 is provided with a through-hole 15, and the lower part of the frustum 3 passes through the through-hole 15 and is fixed to the turntable of the hollow rotary table 2. The through-hole 15 is a clearance structure to facilitate the connection between the frustum 3 and the hollow rotary table 2.

[0019] like Figure 4 As shown, in some embodiments, the positioning fixtures 4 are evenly distributed on the frustum 3, and the positioning fixtures 4 are provided with contoured grooves 16.
