Description

Technical Field

[0002] During the production and assembly of electronic products such as mobile phones, several electronic components need to be mounted on the motherboard or casing. Currently, in some assembly factories, during the patch processing, the components on the material strip are usually removed manually and then mounted one by one. When manually removing the material, the material strip is usually wound on the material roll, and the components on it are removed using a fixture for mounting. Due to the relatively traditional feeding method of electronic components, the efficiency of the patch process is low. At the same time, the material strips with the components removed are in a messy state, which seriously affects the cleanliness of the processing environment. Moreover, during the device mounting process, the mounting accuracy is heavily dependent on manual observation. Low lighting brightness will also seriously affect the mounting accuracy.

[0032] The embodiment of the present invention provides a double-head feeding device, which includes a machine 100, and a feeding mechanism 200 and a conveying mechanism 300 are arranged on the table of the machine 100, wherein the feeding mechanism 200 includes two feeders 210 arranged side by side, and the feeder 210 includes a frame 211, a discharge shaft 212, a material stripping plate 213, a waste wheel 214 and a material receiving motor (not shown in the figure), the frame 211 is vertically arranged on the table of the machine 100, one end of the discharge shaft 212 is rotatably connected to one end of the frame 211, and the other end of the discharge shaft 212 extends toward the outside of the frame 211, the material stripping plate 213 is arranged at the end of the frame 211 away from the discharge shaft 212, the waste wheel 214 is located between the discharge shaft 212 and the material stripping plate 213, one end of which is rotatably connected to the frame 211, and the horizontal height of the circumferential surface of the upper side of the waste wheel 214 is high.
