Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching parts to a television receiver, and an object of the present invention is to provide a device that streamlines assembly and reduces material costs.

To explain an example of a conventional cabinet of this type, as shown in FIGS. 1 and 2, first a picture tube 1 to be installed is
Cover the outer periphery of the front end with a pressed rim band 9,
A polyester resin or the like is injected into the gap between the picture tube 1 and the rim band 9, and is fixed by reaction hardening.

Reference numeral 7 designates mounting ears fixed to the four corners of the rim band 9 by welding.

In Fig. 3, 2 is the cabinet body, and the mounting plate 3
A resin-molded base 5 for the mounting bolt 4 is attached to the base 5, a rubber washer 6 is placed on the base 5, the lug 7 of the picture tube 1 is passed through the bolt 4, and a nut 8 with a washer is screwed onto the bolt 4 to receive the image. Tube 1 was fixed.

Further, many other parts such as the tuner block 12 are attached to a resin escutcheon 11, and this escutcheon 11 is attached to the cabinet 2 with screws.

The present invention provides a method for attaching parts that makes it easier to attach parts and reduces costs.One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 4, 13 is a cabinet, and an escutcheon 15 is fitted in the front surface thereof.

Reference numeral 16 denotes a component attachment body to which the picture tube 14 and tuner block 17 can be attached, and is fixed to the cabinet 13 with screws 18 and 19.

Details of the component mounting body 16 are shown in FIGS. 5 and 6.

The picture tube 14 is first placed at a predetermined position in a mold for molding the component mounting body 16.

Next, resin is injected into this mold at low pressure or normal pressure to form a molding bottom.

After this, the mold is removed to obtain a resin component mounting body having a size that almost covers the entire opening of the television receiver.

As this resin, it is desirable to use a resin that has good adhesion to the glass of the picture tube, so that the degree of adhesion to the picture tube 14 can be increased.

For example, Ultan's low-pressure injection molding method is suitable.

Alternatively, a method of low-pressure injection of a reactive resin may be used, and polyester resins, epoxy resins, etc. can be used.

The picture tube must not crack due to pressure during resin injection, and molding processes such as low-pressure molding, low-pressure foam molding, normal pressure molding, casting, laminating, coating, and laminating are preferable.

When molding the picture tube 14, if there are other parts 17 etc. that can be molded at the same time, they can be molded at the same time.

Furthermore, mounting spaces 20, 21, and 22 can be provided at the positions of parts to be mounted later on the component mounting body 16.

23 is a fixing part for fixing this component mounting body 16 to the mounting piece 25 of the cabinet 13 with screws 18 and 19; 24 is a part for clamping the locking piece 26 of this escutcheon 15 when fixing the escutcheon 15 to the cabinet 13; This is a protrusion for regulating the position of the component mounting body 16 and for positioning the component mounting body 16 in the cabinet 13.

In this way, there is no need to attach a rim band to the picture tube, and the picture tube is directly molded and fixed with resin, so it is possible to improve the mounting efficiency and reduce the number of parts, thereby reducing costs.

Moreover, other parts can also be attached to this resin-made component attachment body, and a large number of parts can be assembled and attached to one component attachment body, resulting in excellent work efficiency.

Further, since the parts can be mounted by positioning the parts mounting body horizontally and from one side, it is possible to easily automate parts mounting by a machine.

Furthermore, since the number of parts to be attached to the cabinet itself can be reduced, workers can be freed from working in narrow spaces inside the cabinet, and occupational diseases can be eliminated.

In factories, when performing assembly line work, parts were placed on a pallet on a belt conveyor, but the parts mounting body can be replaced with a pallet, eliminating the need for a pallet.

The dimensional accuracy of the parts mounting body is good and the quality is improved.

Since there is no need to attach parts to the escutcheon or cabinet, it is easy to standardize the parts mounting body and to diversify the designs of the escutcheon or cabinet.
