Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a device structure for pasting electronic components onto the inner side wall of an electronic watch frame, so as to provide a hardware basis for automated production.

[0004] To solve the above technical problem, the utility model provides the following technical solution: A structure of an assembly and pressure maintaining device includes a turntable, a three-dimensional motion system, a feeder, and a pressure maintaining device. Product fixtures are provided on the turntable. The three-dimensional motion system, the feeder, and the pressure maintaining device are distributed around the turntable. The number of feeders is two sets, and the number of three-dimensional motion systems is two sets. One set of three-dimensional motion system cooperates with one set of feeder to work. Each set of three-dimensional motion system is equipped with a material sucking and chip mounting mechanism. There are four stations around the turntable, including a loading and unloading station, two chip mounting stations, and a pressure maintaining station. The two sets of feeders are respectively located at the two chip mounting stations, and the pressure maintaining device is located at the pressure maintaining station.

[0005] At the loading and unloading station, a worker positions the electronic watch frame on the product fixture. The turntable rotates to the chip mounting station. The feeder supplies small sheet-shaped electronic components. Driven by the three-dimensional motion system, the material sucking and chip mounting mechanism obtains the electronic components from the feeder and attaches them to the inner side wall of the electronic watch frame. The turntable rotates to the pressure maintaining station, and the pressure maintaining device performs pressure maintaining on the electronic components attached to the inner side wall of the electronic watch frame.

[0006] The material sucking and chip mounting mechanism of the utility model attaches the electronic components to the inner side wall of the electronic watch frame, that is, chips are mounted.

[0007] The utility model has two chip mounting stations, and can attach two kinds of electronic components to the inner side wall of the electronic watch frame.

[0008] The utility model provides a hardware basis for the automated production of chip mounting for electronic watches.

[0009] The product fixture includes a fixture backplane installed on a fixture bracket, a fixture main body connected to the fixture backplane, and a pair of fixture pressing blocks elastically fitted in the fixture main body. The pair of fixture pressing blocks are arranged facing each other vertically. A cam wrench is clamped between the fixture backplane and the fixture main body. Each fixture pressing block is provided with a convex portion, and the cam wrench contacts the convex portion. The cam wrench is in a Y-shaped fork shape, with cam portions provided at two ends of the three ends, and the other end is a handle. The two cam portions respectively contact the convex portions of the pair of fixture pressing blocks. The worker rotates the cam wrench through the handle, and the two cam portions respectively act on the convex portions to drive the pair of fixture pressing blocks away from each other. The worker places the electronic watch frame between the pair of fixture pressing blocks, and the electronic watch frame is placed vertically. The worker rotates the cam wrench back. Under the action of the elastic force, the pair of fixture pressing blocks reset, that is, the pair of fixture pressing blocks move closer to each other to clamp the electronic watch frame. The product fixture of the present utility model is vertically arranged, so that the electronic watch frame is vertically fixed, providing favorable conditions for the subsequent suction and mounting mechanism to attach electronic components to the inner side wall of the electronic watch frame.
