Description

Technical Field

[0001] The utility model relates to the field of display screen production equipment, in particular to a glue dispensing and pressure-maintaining fixture for a watch display module. Background Art

[0002] In the process of assembling electronic products, glue bonding is often used to achieve a seamless combination of two parts of the product, such as between the middle frame and the decorative ring of the display screen. After the two parts are coated with glue, pressure maintenance is required to ensure the stability of the adhesion, and pressure maintenance is generally achieved using a pressure maintenance fixture. Traditionally, when performing pressure maintenance, the two products are directly placed on the upper pressure plate and the lower placement plate, and then the two products are squeezed by moving the upper pressure plate. However, the middle frame and the display screen of the electronic product are prone to offset during the extrusion and bonding, resulting in pressure maintenance failure.

[0003] To this end, the prior art (announcement number: CN220128611U, announcement date: 2023.12.05) discloses a TP pressure holding fixture, which limits the left and right sides of the middle frame and the display screen after the electronic product is bonded by setting a fastening component. After limiting, the limiting component is activated to limit the front and back sides of the middle frame and the display screen. After limiting, the pressure holding plate can effectively prevent the display screen from offset when maintaining pressure.

[0004] However, for small watch screens, since most watch screens are round in shape, different pressure holding fixtures are required when producing watch screens of different sizes, which is costly. In addition, round watch screens are difficult to install and fix accurately, which makes the pressure holding positioning prone to deviations. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0006] A glue dispensing and pressure-maintaining fixture for a watch display module comprises a machine platform, a base and a pressure-maintaining plate, wherein the base is fixedly mounted on the machine platform, and the pressure-maintaining plate is arranged above the base;

The columns are slidably installed in the vertical sliding holes one by one, and the two columns are arranged behind the base and the pressure maintaining plate.

[0014] Furthermore: a vertical plate is fixedly installed on the rear side of the machine, a hand press is fixedly installed on the top side of the vertical plate, and the hand press drives the pressing lifting platform to move up and down.

[0015] Further: the hand press includes a side frame, a rotating frame, a hand rod, a connecting rod and a spring pressing rod. The side frame is fixedly installed on the top end of the front side of the vertical plate, the rotating frame is fixedly installed on the front side of the side frame, the hand rod is rotatably installed on the upper end of the rotating frame, the connecting rod is hingedly installed between the middle part of the hand rod and the spring pressing rod, and a positioning cylinder is formed at the bottom end of the front side of the rotating frame.
