The substrate 113 is used to fix the protective polishing tool 100 on other parts, so as to ensure the stability of the polishing operation, and the carrier plate 115 is used to place the workpiece to be polished.

Referring to fig. 3, in the illustrated embodiment, the substrate 113 is substantially square in shape. The substrate 113 has a mounting surface 1131 and four side surfaces 1133 surrounding the mounting surface 1131. The shape of the carrier plate 115 matches the shape of the substrate 113. The carrier plate 115 is fixed to the mounting surface 1131 of the substrate 113. By matching the shape of the carrier plate 115 with the shape of the substrate 113, the structure of the polishing protection fixture 100 is more compact and neat. The shape of the substrate 113 is not limited to a square shape, and may be other shapes, for example, a circular shape. The shape of the carrier plate 115 is not limited to match the shape of the substrate 113, and may be other shapes, such as a circle.

Referring to fig. 4 and 5, the carrier 115 has a carrier 1151 for placing a workpiece to be polished. The susceptor 1151 is disposed on the susceptor 111 and located in the predetermined region 1111. The shield 120 is disposed around the carrier stage 1151. The guard 120 abuts the member to be polished when the member to be polished is on the carrier table 1151. This arrangement allows the guard 120 to closely fit the member to be polished, so as to protect the member to be polished better.

In the illustrated embodiment, the buffer 130 is secured to the side 1133 of the substrate 113.

Further, the buffer 130 can buffer the force applied to the buffer 130 by the guard 120. The buffering member 130 buffers the acting force of the protection member 120 to reduce the action of the member to be ground, so that the member to be ground is better protected. Further, the buffer 130 is a hydraulic limit buffer. This arrangement can absorb the acting force of the shielding element 120, and provide an elastic restoring force to the shielding element 120 to push the shielding element 120 to move away from the base 110, so as to reposition the side of the shielding element 120 away from the base 110, and can control the distance that the shielding element 120 moves away from the base 110 by absorbing the acting force of the shielding element 120, so as to reposition the side of the shielding element 120 away from the base 110 to a preferred position.

Referring to fig. 1 again, there are a plurality of buffers 130. The plurality of buffering members 130 are disposed around the predetermined region 1111 for one circle. Each cushion member 130 abuts against the guard member 120. By providing the plurality of bumpers 130, the protection element 120 is subjected to a relatively uniform elastic restoring force, so that the protection element 120 can move away from the base 110 smoothly. In the illustrated embodiment, there are sixteen bumpers 130. Four spaced buffers 130 are fixed to each side 1133 of the substrate 113. The number of the buffering members 130 is not limited to sixteen, may be eight, may be twenty, and the like, and may be set as needed, so as to ensure that the buffering members 130 can push the protection member 120 to move in a direction away from the base 110.

The grinding protection fixture 100 includes a base 110, a protection component 120 and a buffer component 130, wherein the base 110 has a supporting surface 111, the supporting surface 111 has a predetermined area 1111 for placing a to-be-ground component, the protection component 120 is disposed on the supporting surface 111 and surrounds the predetermined area 1111 for a circle, so that the protection component 120 can protect the to-be-ground component when the to-be-ground component is disposed at the predetermined area 1111 of the supporting surface 111, the buffer component 130 is fixed on the base 110 and abuts against the protection component 120, one side of the protection component 120 away from the base 110 is moved in a direction close to the base 110 by a grinding disc or a polishing wheel during grinding, the buffer component 130 abutting against the protection component 120 is elastically deformed by an acting force of the protection component 120, the elastically deformed buffer component 130 provides an elastic restoring force for the protection component 120 to push the protection component 120 to move in a direction away from the base 110, while the side of the guard 120 remote from the base 110 is repositioned. The protective polishing jig 100 can automatically adjust the height of the protective element 120 (i.e., the distance from the side of the protective element 120 away from the base 110 to the base 110) by providing the buffering element 130, thereby preventing the to-be-polished element from polishing and collapsing, prolonging the service life of the protective element 120, reducing the replacement frequency of the protective element 120, being beneficial to reducing the cost and improving the production efficiency.

Generally, the guard 120 is fixed to the base 110 by screws and cannot be moved. The worn guard 120 is difficult to protect the member to be ground, resulting in high roll off and a high defective rate of the member to be ground. If the height of the shielding member 120 is adjusted, the screws are loosened, and a spacer is disposed between the shielding member 120 and the base 110 to elevate the shielding member 120. Such an arrangement is complicated to operate and does not allow for automatic adjustment of the height of the guard 120 in real time. In the grinding protection jig 100 of the present study, the height of the protection element 120 is automatically adjusted in real time through the buffering element 130, the protection element 120 does not need to be artificially lifted, the operation is simple, and the edge collapse and the defective rate of the element to be ground are reduced.

The present application further provides a polishing apparatus including the above polishing protection fixture 100. The grinding protection jig 100 can automatically adjust the height of the protection element 120 by arranging the buffer element 130, so that the service life of the protection element 120 is long, the replacement frequency of the protection element 120 is low, and the service life and the production efficiency of the grinding device are favorably improved.
