Abstract

The utility model relates to a heterogeneous medium composite grinding locating ring which comprises an upper ring body and a lower ring body. The upper ring body and the lower ring body are overlapped in sequence, combined with each other and both made of plastic materials. Due to the fact that the heterogeneous medium composite grinding locating ring is made of the plastic materials, metal materials or plastic materials with high cost are saved. The heterogeneous medium composite grinding locating ring is divided into the upper ring body (a base portion) and the lower ring body (a grinding portion), and therefore when the lower ring body (the grinding portion) is ground and consumed, the upper ring body (the base portion) does not need to be changed along with the lower ring body (the grinding portion) in an integrated mode. Therefore, the cost of the plastic materials is saved and the economical effect is achieved.

Description

The Heterogeneous Composite grinding positioning ring

Technical field

The utility model is about a kind of grinding positioning ring, espespecially a kind of Heterogeneous Composite grinding positioning ring for wafer location grinding operation.

Background technology

Press, the structure of the grinding positioning ring that general grinding wafer operation is used, in the past made with integrally formed material, after have and consider the base portion ring body and grind ring body its function is respectively arranged, therefore have and develop heterogeneous (different material) as the structure of composite bed, the structure that presents as TaiWan, China new patent No. M347978 " structure-improved of grinding positioning ring ", one base portion, it adopts by stainless steel or metal alloy made, and be an annular aspect, the first side of this base portion is a locking face, is provided with locating hole on locking face; The second side of base portion is a faying face, is provided with conjugate foramen on faying face, and this conjugate foramen can be established the locking joint element in order to connect.One grind section, it adopts by macromolecule plasticity material made, and is an annular aspect, and the first side of this grind section is a faying face, is provided with entrance hole on faying face; The second side of grind section is an abradant surface.

By the grinding ring body of the base portion ring body of metal and a macromolecule material mutually combine consist of, present respectively different effects." heterogeneous " that yet this prior art presents is higher stainless steel or metal alloy take base material as common hardness, yet grind section adopts the lower macromolecule plasticity material of relative hardness.

Though this case emphasis finds expression in response to grinding positioning ring in the attrition process process, produce the violent rubbing action of continuation between meeting and wafer and processing parts, the reversal of stress that it produces, can be to the base portion ring body and the integrated structure that grinds ring body of grinding positioning ring, produce destructive effects, in case base portion ring body and grind and to produce loosening between ring body or when throwing off the phenomenon of peeling off, that is be equal to this grinding positioning ring and scrap, and need separately change.Therefore Special attention will be given to is in the fastness of both integrated structure, but the hierarchy structure that this case presents, as grinding-material with the hardness junior, thereby the loss of material is comparatively serious, and this case with hardness the higher person as base material, therefore its toughness is also relative low with compliance, therefore still has improved space.

Although, also having the dealer to adopt plastics (for example PPS) is that a base portion and a grind section are formed in one, do not reduce production costs though can not use metal, but owing to being one, therefore be worn and when consuming when grind section, even if base portion does not have attrition, but also must be in company with this grind section one replacing, but because these plastics (PPS) expense is immeasurable, also belong to waste with uneconomical.

The utility model content

The technical problem that the utility model solves is to provide a kind of Heterogeneous Composite grinding positioning ring, comprises a pressed on ring and once encircles, and both sequentially fold and merge into combination, and this pressed on ring and lower ring are all made with the plasticizing material, the composite bed effect that both has concurrently.

The technological means that the utility model adopts is as described below.

A kind of Heterogeneous Composite grinding positioning ring comprises a pressed on ring and encircles that both sequentially fold and merge into combination once, and this pressed on ring and lower ring are all made with the plasticizing material.

The hardness of this time ring is higher than this pressed on ring.

Between this pressed on ring and this time ring, more lining is established a gasket ring, forms multiple field with order.

The hardness of gasket ring is between this pressed on ring and this time ring.

this time ring is selected from polyphenylene sulfide (polyphenylene sulfide, PPS), polybutylene terepthatlate (polybutylene terephthalate, PBT), carbon fills polyether-ether-ketone (carbin-filled PEEK), PEI (polyetherimide, PEI), polyether-ether-ketone (polyether ether ketone, PEEK), polyethylene terephthalate (polyethylene terephthalate, PET), polytetrafluoroethylene (PTFE) (polytetrafluoroethylene, PTFE), polybenzimidazoles (polybenzimidazole, PBI), polyamine-acid imide (polyamide-imide, PAI), polyethylene terephalic acid fat (PETP), polyvinyl chloride (PVC), nylon (NYLON), polyacetals (POM), ABS, iron is dragon (PTFE) not, poly-one of the inferior ethene PVDF or any compound more than two kinds that fluoridizes.

The beneficial effect that the utility model produces is as described below.

Because the utility model adopts plastifying material, all made to save higher metal or the plastifying material of cost with the plasticizing material.

And the utility model is divided into a pressed on ring (base portion) and encircles (grind section) once, therefore ring (grind section) is worn and when consuming instantly, pressed on ring (base portion) need not be changed in company with this time ring (grind section) one, therefore can save the expense of this plastifying material, and reach economic effect.And should be noted that, this case is not the expection effect of being reached with the change of material merely, and with the space kenel compared to the reverse Boulez of prior art, the effect that coordinates material to reach.

The figure number explanation:

1 Heterogeneous Composite grinding positioning ring

11 pressed on rings

12 times rings

13 gasket rings

1A has the Heterogeneous Composite grinding positioning ring that groove is set.

The specific embodiment

See also Fig. 1, the utility model is about a kind of Heterogeneous Composite grinding positioning ring 1, see also shown in Figure 2, comprise a pressed on ring 11 and encircle 12 once, both are sequentially folded merges into combination, and this combination can be with common known combined structures such as binding member or fusions, and this pressed on ring 11 is all made with the plasticizing material with lower ring 12, because the utility model adopts plastifying material, all made to save higher metal or the plastifying material of cost with the plasticizing material; And the utility model is divided into a pressed on ring (base portion) and encircles (grind section) once, therefore ring (grind section) is worn and when consuming instantly, pressed on ring (base portion) need not be changed in company with this time ring (grind section) one, therefore can save the expense of this plastifying material, and reach economic effect.And should be noted that, this case is not the expection effect of being reached with the change of material merely, and with the space kenel compared to the reverse Boulez of prior art, the effect that coordinates material to reach.
