Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a foam attaching fixture. Background Technology

[0002] According to the production process requirements, foam needs to be attached to designated positions during the production of mobile phone cases. In the past, foam attachment was mostly done manually, which resulted in low efficiency and low attachment accuracy. Even when using attachment fixtures, the existing fixtures have two different parts for positioning the foam and positioning the mobile phone case, which increases assembly errors. Moreover, the foam needs to be fixed by vacuum adsorption, and the vacuum generator needs to work continuously after the foam is installed until it is manually turned off, which increases costs and causes prolonged noise. Utility Model Content

[0003] The purpose of this invention is to provide a foam attaching fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A foam attaching fixture includes an electrical control box and a positioning assembly, a vacuum generator, and a vacuum shut-off trigger switch mounted on the control box. The positioning assembly includes a base plate, guide posts, guide sleeves, springs, an adsorption seat, and a positioning base. The base plate is fixed to the electrical control box. At least two guide posts are provided and fixed above the base plate. Limiting heads are installed at the upper ends of the guide posts. The positioning base is slidably connected to the guide posts via the guide sleeves. The springs are sleeved on the guide posts, with their two ends respectively contacting the base plate and the guide sleeves. The positioning base has foam positioning holes and several limiting protrusions. A block surrounds and forms a phone case placement area; a trigger post is fixed to the bottom of the positioning seat; a clearance hole is provided on the base plate corresponding to the trigger post position; the adsorption seat is fixed on the base plate; a foam support block extending into the foam positioning hole is provided above the adsorption seat; a plurality of adsorption holes are provided on the foam support block; an installation groove is provided on the electrical control box corresponding to the lower part of the trigger post; a vacuum shut-off trigger switch is installed in the installation groove; the vacuum shut-off trigger switch is electrically connected to the vacuum generator; the vacuum generator is installed on one side of the electrical control box and connected to the adsorption seat through an air pipe.

[0006] In a further description of this utility model, the positioning seat is provided with material loading and unloading openings at the middle positions of the left and right sides.

[0007] Further description of this utility model: the foam positioning hole is formed at the rear of the positioning seat; the limiting protrusions are respectively a front limiting protrusion, a rear limiting protrusion, a left limiting protrusion, and a right limiting protrusion; the front limiting protrusion is located at the middle position of the front end of the positioning seat; the rear limiting protrusion is located on the rear side of the foam positioning hole; the left limiting protrusion has two protrusions located on the front and rear sides of the material loading and unloading clearance opening on the left side; the right limiting protrusion has two protrusions located on the front and rear sides of the material loading and unloading clearance opening on the right side.

[0008] In a further description of this utility model, the base plate is provided with two limiting posts distributed on the left and right sides.

[0009] As further described in this utility model, the vacuum generator is installed on the rear side of the electrical control box.

[0010] In a further description of this utility model, four guide posts are provided and distributed at the four corners.

[0011] The beneficial effects of this utility model are as follows:

[0012] This design uses a positioning seat to position the foam and the phone case, improving the positional accuracy between them. The foam is placed into the foam positioning hole and supported by the foam support block. The vacuum generator is activated, and the suction seat adheres to and fixes the foam. The phone case is then placed on the phone case placement part and limited by the limiting protrusion. Pressing down on the phone case moves the positioning seat downward, causing the phone case to move downward relative to the foam, achieving a fit between the phone case and the foam. After pressing down, the vacuum off trigger switch at the top of the column is activated, which controls the vacuum generator to stop working, thereby reducing air consumption and noise.
