Description

Amusement wheel disc

Technical Field

The utility model relates to a wafer processing technology field, concretely relates to loose pulley dish.

Background

In the wafer course of working, thickness processing (grinding, polishing) to the wafer has become an indispensable process, the grinding and polishing equipment adopts the trip wheel dish to put the wafer of treating processing in the die cavity of trip wheel dish, be equipped with the ring gear at trip wheel dish outer lane, ring gear and the meshing of the ring gear on the lower wall of grinding and polishing equipment, the lower mill passes through the ring gear and drives the trip wheel dish and rotate, thereby the drive is placed in the operation of the wafer of trip wheel dish die cavity, through the pressure of mechanical upper and lower quotation on the grinding and polishing equipment, make the wafer constantly extrude and wear in the grinding quotation, finally produce deformation and reach the thickness requirement. The travelling wheel disc in the prior art is generally made of common resin materials or spring steel integrally, and in the process of meshing the gear rings, the gear ring gear on the outer ring of the travelling wheel disc is easy to deform and wear due to stress, so that the rotation of the travelling wheel disc is influenced, the processing quality and precision of a wafer are influenced, the stability of wafer processing is low, frequent replacement is needed, and the processing cost is increased.

Disclosure of Invention

The utility model aims at overcoming the not enough of existence among the prior art, provide a simple structure, reliability height, reduction processing cost for the trip rim plate of wafer grinding and polishing usefulness.

According to the utility model provides a technical scheme, the trip rim plate, including the trip rim plate body, the trip rim plate body includes the loose pulley die cavity and locates the ring gear in the loose pulley die cavity outside, its characterized in that: the gear ring is composed of a plurality of carbon fiber layers.

Further, the multiple carbon fiber layers of the gear ring are bonded through an epoxy resin bonding agent.

Furthermore, the through hole arranged in the loose pulley cavity is circular, triangular, square or hexagonal.

Furthermore, through holes in the loose pulley cavity are uniformly distributed along the circumference.

Furthermore, the loose pulley cavity is detachably arranged on the inner side of the gear ring and is linked with the gear ring.

Further, the loose pulley cavity is connected with the gear ring through a buckle.

The utility model has the advantages that: the gear ring structure formed by the wear-resistant multi-layer carbon fiber layers improves the service life and the strength of the free wheel disc, not only can the cost be reduced, but also the reliability of a workpiece can be improved, and therefore the processing quality and the processing precision of a wafer are improved. The utility model has the advantages of being simple in structure and convenient in operation, can get fast the loose pulley dish of different specifications, shape through split type structural design and put, improve machining efficiency.

Drawings

Fig. 1 is a schematic structural view of the travelling wheel disc of the present invention.

Description of reference numerals: 1-loose pulley cavity, 2-gear ring and 3-through hole.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the utility model relates to a loose pulley dish includes the loose pulley dish body, the loose pulley dish body includes loose pulley die cavity 1 and locates the ring gear 2 in the loose pulley die cavity outside, ring gear 2 is by the adhesive multilayer carbon fiber layer of epoxy binder bonding. The utility model discloses the ring gear adopts wear-resisting multilayer carbon fiber layer to constitute, can improve the holistic life of trip rim plate, reduce cost, the utility model discloses structure trip rim plate is 20 times that adopts ordinary resin material trip rim plate life-span, is 5~10 times that adopts spring steel material trip rim plate life-span. And adopt the utility model discloses the structure can also improve the holistic use intensity of trip rim plate, makes the reliability of wafer processing high, improves processingquality and precision.

The through hole 3 arranged in the loose pulley cavity is round, triangular, square or hexagonal. The through holes 3 are evenly distributed along the circumference.

The loose pulley cavity 1 is detachably arranged on the inner side of the gear ring 2, and the loose pulley cavity 1 is connected with the gear ring 2 through a buckle. Traditional integral type trip rim plate need frequently get when processing the wafer of different specifications, shape and puts the trip rim plate, and the tight fit is inlayed with the ring gear engagement on the lower wall to the trip rim plate ring gear after the processing, gets to put the trip rim plate and wastes time and energy relatively, the utility model discloses loose pulley die cavity and ring gear design are split type structure, and the loose pulley die cavity of placing the wafer can conveniently break away from with the ring gear, can treat the wafer of the different specifications of processing, shape and get and put easy operation, save the activity duration to improve machining efficiency.
