Description

Dispensing continuous and balanced pressure holding device for precision structural parts

technical field

The utility model relates to a device for dispensing glue with continuous and balanced force and pressure maintaining for precision structural parts.

Background technique

As people have higher and higher requirements for the appearance of precision structural parts, the novel and flawless appearance can always attract the attention of consumers. At present, most of the precision structural parts of electronic consumer products have used plastic parts and metal parts or plastic lenses by dispensing glue. Combine it with assembly to achieve the metal appearance or window effect of electronic consumer products. However, when dispensing and assembling plastic parts and metal parts or plastic lenses, abnormalities such as weak bonding with metal parts or plastic lenses, excessive assembly gaps, uneven assembly warping, and low waterproof grades often occur. The root cause of the abnormalities is After dispensing glue on metal parts or plastic lenses, the continuous and balanced force and pressure cannot be effectively carried out, so that the glue can be evenly dispersed and cured and assembled perfectly.

Utility model content

In order to overcome the defects of the prior art, the utility model provides a continuous and balanced pressure-holding device for dispensing precision structural parts. The technical solution of the utility model is:

The dispensing device for continuous and balanced force and pressure holding of precision structural parts includes an upper cover, a middle cover and a lower cover assembled together in sequence from top to bottom. The upper cover is provided with an upper insertion interface. The lower end surface is vertically installed with several upper insertion columns with hooks and several spring seats, each spring seat is equipped with a spring; the middle cover is provided with a middle insertion interface, and the upper end surface of the middle cover There are several uprights and several middle plug-in posts with hooks installed vertically, each upright corresponds to a spring, and the spring is sleeved on the periphery of the upright, and the middle part of the lower cover forms a processing area. The side is provided with several lower plug-in interfaces, the middle plug-in column extends upwards through the upper plug-in interface, and the hook on the middle plug-in post is limited by the upper cover; the upper plug-in post is downward Through the middle insertion interface and the lower insertion interface in turn, the hook on the upper insertion post is limited by the lower cover.

Each of the spring seats includes two opposite arc-shaped plates. The two arc-shaped plates are perpendicular to the upper cover and form a cavity for accommodating springs between them.

The section of the column is trapezoidal.

The utility model has the advantages of:

1. Solve the functional problem of weak bonding between plastic parts and metal parts or plastic lenses.

2. Solve the appearance problem of large assembly gap between plastic parts and metal parts or plastic lenses.

3. Solve the appearance problem of warping of plastic parts and metal parts or plastic lenses.

4. Solve the functional problem of low waterproof level of plastic parts and metal parts or plastic lenses.

Detailed ways

The utility model will be further described below in conjunction with specific embodiments, and the advantages and characteristics of the utility model will become clearer along with the description. However, these embodiments are only exemplary, and do not constitute any limitation to the scope of the present utility model. Those skilled in the art should understand that, without departing from the spirit and scope of the utility model, the details and forms of the technical solution of the utility model can be modified or replaced, but these modifications and replacements all fall within the protection scope of the utility model .

Referring to Fig. 1 and Fig. 2, the utility model relates to a continuous and balanced pressure-holding device for dispensing glue for precision structural parts. Taking the combination of plastic parts and steel sheets as an example, it includes upper parts assembled together from top to bottom. The cover 1, the middle cover 2 and the lower cover 3 are provided with an upper insertion interface 9 on the upper cover 1. The lower end surface of the upper cover 1 is vertically installed with several upper insertion columns 4 with hooks and several A spring seat 6, a spring 7 is installed on each spring seat 6; the middle cover 2 is provided with a middle insertion interface 10, and several columns 8 and several cards with cards are vertically installed on the upper end surface of the middle cover 2. The middle insertion column 5 of the hook, each column 8 corresponds to a spring 7, the spring 7 is sleeved on the periphery of the column 8, the cross section of the column 8 is trapezoidal, and the middle part of the lower cover 3 is formed. Area 13 (the plastic parts 12 to be processed and the steel sheets 11 combined with the plastic parts 12 are installed in the processing area), several lower insertion interfaces 14 are arranged on the side of the processing area, and the middle insertion column 8 is upward Extending through the upper insertion interface 9, the hook on the middle insertion post 8 is limited by the upper cover 1, and the upper cover and the middle cover are assembled together through the middle insertion post; the upper insertion post 4 Pass through the middle insertion interface 10 and the lower insertion interface 14 in turn downwards, the hook on the upper insertion column 4 is limited by the lower cover 3, and the middle cover and the lower cover are assembled together through the upper insertion column. The setting of the spring realizes the extrusion of the spring to the middle cover, thereby ensuring the tight fit between the middle cover and the lower cover.

Each of the spring seats 6 includes two opposite arc-shaped plates, the two arc-shaped plates are perpendicular to the upper cover, and form a cavity for accommodating the spring 7 between them.
