Dispensing and pressure keeping device

Abstract

The invention discloses a dispensing pressure maintaining device which comprises a pretightening unit and a locking unit for locking the pretightening unit. The pretightening unit comprises a bottom plate and a cover plate and further comprises at least two product clamping parts and at least two cover clamping parts, wherein the product clamping parts are arranged on the sides of the bottom plate and used for clamping the side faces of a machine body, and the cover clamping parts are arranged on the side faces of the cover plate and used for clamping the bottom plate. The two opposite side faces of the cover plate are each provided with at least one cover clamping part, and the two opposite side faces of the bottom plate are each provided with a product clamping part. The locking unit comprises an upper pressure maintaining cover, a lower pressure maintaining cover and a sliding block locking unit mounted in the lower pressure maintaining cover and used for pressing the side faces of the machine body. Sliding block moving slopes are arranged on the outer side faces of the sliding block locking unit. Sliding block guiding slopes attached to the sliding block moving slopes are arranged in the upper pressure maintaining cover. By means of the dispensing pressure maintaining device provided by the invention, the universality of the device is improved while dispensing pressure maintaining quality of electronic products is improved.

Description

technical field [0001] The invention relates to the technical field of glue dispensing processing of electronic products, in particular to a glue dispensing and pressure maintaining device. Background technique [0002] In the assembly process of electronic products, such as mobile phones, MP4 or MP5, etc., especially on the metal decoration parts of mobile phones, the side frames of electronic products are bonded sequentially by multiple side strips. In order to ensure the bonding quality, after dispensing glue Pressing through the dispensing and pressure-holding device. [0003] The traditional dispensing and pressure maintaining device includes a pre-tensioning device and a locking device that locks the pre-tensioning device, wherein the pre-tensioning device includes a base and a top cover, and the locking device is a buckle that fastens the base and the top cover together, wherein the base The upper surface is the bottom plate that is used to contact the fuselage, and ...

AI Technical Summary

Problems solved by technology

[0004] However, since the base is only the bottom plate where the upper surface touches the fuselage, during the assembly process of the glue dispensing and pressure maintaining device, since the side of the fuselage has just finished dispensing glue, the side strips of the fuselage are easy to It deforms or pops open under the action of its own force, and the cover plate is only the cover plate that touches the upper surface of the fuselage. During the assembly process of the dispensing and pressure maintaining device, because the cover plate is simply placed on the fuselage, it cannot The body is pre-tightened smoothly, making the dispensing and pressure-holding quality of electronic products poor

[0005] On the other hand, the locking device is only a buckle, and the side of the fuselage is limited and locked by the side of the buckle abutting against the side of the fuselage, which leads to the fact that each type of dispensing and pressure-holding device can only be used for locking One model body, making the dispensing and pressure holding device less versatile
