Embodiment Construction
[0014] The present invention provides a dressing device for dressing the polishing surface of a polishing pad, and the present invention will be further described below through the description of drawings and specific embodiments.
[0015] figure 1 It is a structural schematic diagram of the present invention. The output end of the rotation motor 8 is connected with the second synchronous pulley 6, and drives the first synchronous pulley 5 to rotate through the synchronous belt 7. The center of the first synchronous pulley 5 is successively installed with the rotatable part 3, the universal joint 2 and the final execution Part 1, the final executive part 1 is driven to rotate by the rotation motor 8 through the synchronous belt 7, and the universal joint 2 transmits torque and down force while realizing the self-adaptation of the dressing disc 14 to ensure that the dressing disc 14 is parallel to the polishing pad. The rotation motor 8 directly drives the synchronous belt pul...
