Problems solved by technology

Therefore, the position when the upper plate 113 stops rotating still cannot be grasped accurately
In this way, the final position of the substrate 112 may not be at the predetermined position P2 as shown in FIG. 1B
That is to say, in the case of FIG. 1B, the robotic arm still cannot accurately remove the substrate 112
[0005] To sum up, since the final stop position of the upper plate of the traditional swing arm grinding device cannot be accurately grasped, the substrate cannot be located at the predetermined position
At this time, it is difficult to combine the swing arm grinding device and the automation equipment such as the robot arm

[0038] Please refer to FIG. 2 , which is a schematic diagram of a grinding device according to a first embodiment of the present invention. In this embodiment, the grinding device 200 is used as an example for illustration. The grinding device 200 includes a lower plate 211 , an upper plate 213 , a swing detection module 220 , a first deceleration detection module 240 , a rotation detection module 230 , a swing power source 260 , a rotation power source 270 and at least one pin 253 .

[0039] The upper plate 213 is correspondingly disposed above the lower plate 211 . The rotation detection module 230 , the swing detection module 220 and the first deceleration detection module 240 are respectively set corresponding to the upper plate 213 to detect the position of the upper plate 213 respectively. The swing power source 260 is electrically connected to the upper plate 213 . The swing power source 260 controls the swing of the upper plate 213 according to the position of the up...

[0055] The difference between this embodiment and the first embodiment lies in the number of deceleration detection modules. Please refer to FIG. 6 , which shows a schematic diagram of a grinding device according to a second embodiment of the present invention. The grinding device 300 includes a rotation detection module 330 , a first deceleration detection module 340 and a second deceleration detection module 341 . The rotation detection module 330 is arranged corresponding to the upper disk 313 and detects the position of the upper disk 313, so that the rotation power source 370 controls the rotation of the lower disk 311 according to the position of the upper disk 313 detected by the rotation detection module 330, so that the upper disk 313 The rotation changes accordingly. As for the first deceleration detection module 340 and the second deceleration detection module 341, they are used to detect the position of the upper plate 313 respectively, so that the rotating power ...

Abstract

The invention discloses a grinder and a position method thereof. The grinder comprises a lower disk, an upper disk, a swing detection module and a swing power source. The upper disk is correspondingly arranged above the lower dick; the swing detection module is correspondingly arranged to the upper disk to detect the position thereof; the swing power source is electrically connected with the upper disk, and the swing power source is used for controlling the swing of the upper disk basing on the position of the upper disk. The grinder and the position method of the present invention provide a position mechanism for the upper disk, thereby making the precise position of a base board which is adsorbed by the upper disk; therefore, the grinder of the present invention can be combined with the automatic device, thereby reducing the cost and enhancing the competitive power of the industry.

Description

technical field [0001] The present invention relates to a grinding device and its positioning method, and in particular to a grinding device for positioning an upper disc and its positioning method. Background technique [0002] A traditional swing arm grinding device includes a lower plate, an upper plate, a swing source and a rotation source. The upper plate is arranged above the lower plate. The swing source is used to provide a swing power for the upper plate, so that the upper plate can swing relative to the lower plate. The rotation source is used to provide a rotation power for the bottom plate to make the bottom plate rotate. When the upper disc swings and the lower disc rotates, the upper disc rotates relative to the lower disc through the friction force between the upper disc and the lower disc. In this way, if the substrate is adsorbed on the upper disc and faces the lower disc, the substrate is ground by the above-mentioned relative movement of the upper disc ...
