Tool clamp, device and inclined plane pad pasting method for mobile phone volume key SMT mounting

Abstract

The invention discloses a tool clamp, device and inclined plane pad pasting method for mobile phone volume key SMT mounting. The device for mobile phone volume key SMT mounting comprises a machine box(1), an inspection window is arranged on the front surface of the machine box (1), a feeding opening (4) and a discharging opening (5) are formed in the side surfaces of the machine box, a paster mechanism and a conveying assembly (6) are arranged in the machine box (1), and a control panel (7) is arranged on the front surface of the machine box (1); and the conveying assembly (6) comprises a volume key conveying belt and a sponge rubber conveying belt, and the volume key conveying belt and the sponge rubber conveying belt are arranged at the positions, close to the inspection window, in themachine box (1). The device for mobile phone volume key SMT mounting has high mounting efficiency, through the modification of a sucking head, the problem that sponge rubber is pasted on the mobile phone volume key inclined plane is effectively solved, and the pasting effect is further reinforced through the cooperation of a tool seat bottom plate and a pressing plate. The inclined plane pad pasting method has good pad pasting effect and simple operating process.

Description

technical field [0001] The invention relates to the technical field of SMT patching, in particular to a tooling fixture, a device and an inclined-plane film-sticking method for SMT mounting of mobile phone volume keys. Background technique [0002] SMT patch is a surface assembly technology, becoming a surface mount or surface mount technology, which is currently the most popular technology and method in the electronic assembly industry. In mobile phone parts, the volume key is an important part of the mobile phone parts. The general mobile phone volume key is usually composed of an up key and a down key with a slope and a connecting plate for connecting the up key and the down key, such as Figure 6 As shown, in the process of producing the volume key, it is usually necessary to stick the sponge glue on the slope of the upper button and the lower button through SMT technology, but the existing SMT placement machines directly use the suction head to suck up the sponge glue. ...

In mobile phone parts, the volume key is an important part of the mobile phone parts. The general mobile phone volume key is usually composed of an up key and a down key with a slope and a connecting plate for connecting the up key and the down key, such as Image 6 As shown, in the process of producing the volume key, it is usually necessary to stick the sponge glue on the slope of the upper button and the lower button through SMT technology, but the existing SMT placement machines directly use the suction head to suck up the sponge glue. Then the Z-axis moving component is attached to the slope of the volume key, but the effect of the Z-axis driving component on the slope is not good, resulting in only a part of the sponge glue being attached to the slope, even if a rotating component is installed on the suction head, so that the suction head can rotate A certain distance is used to stick the film on the inclined surface, but because it is difficult to control the downward pressure of the suction head, sometimes the volume key will be broken. Using this method will only increase the complexity of the equipment, and it is not easy to control and maintain
