Description

Technical Field

[0001] The utility model relates to the technical field of polishing pads, in particular to a polishing pad dressing device which is easy to adjust. Background Art

[0002] Polishing pads are also called polishing leather, polishing cloth and polishing sheet. They are important auxiliary materials that determine the surface quality in chemical mechanical polishing. They are accessories used for polishing and grinding operations. Polishing pads are composed of fiber fabrics of different materials and foams of different hardness. According to the material, they can be divided into: sponge polishing pads, Yang Mi polishing pads and cotton cloth polishing pads. Among them, sponge polishing pads are the most widely used. Polishing pads can improve the efficiency of polishing and reduce friction during polishing, reduce surface temperature, and thus reduce the risk of burning. Polishing pads need to be trimmed during processing. There are many kinds of polishing pad trimming devices currently available on the market, but there are still some disadvantages;

[0003] For example, in actual use, a general polishing pad dressing device directly dresses the polishing pad, and the polishing pad will move during the dressing process, which will affect the final dressing accuracy. At the same time, the general polishing pad needs to be manually adjusted to move the polishing pad during the dressing process, which is time-consuming and labor-intensive. In addition, a certain amount of debris will be generated during the dressing and grinding process of the polishing pad. If the debris is not processed centrally, the debris will fly around and not only affect the working environment of the operator, but also be inhaled by the operator, which will affect the operator's health. Therefore, we propose a polishing pad dressing device that is easy to adjust to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a polishing pad dressing device that is easy to adjust, including: a support base 1, a threaded rod 2, a support platform 3, a limit rod 4, a motor 5, a polishing pad body 6, a fixing frame 7, a pressing plate 8, a connecting rod 9, an electric telescopic rod 10, a blade 11, a support rod 12, a folding tube 13, a fixing rod 14, a hydraulic rod 15, a sliding block 16, a slide rail 17, a controller 18, an absorption box 19, an absorption tube 20, an exhaust fan 21 and a debris box 22;

[0027] like Figure 1 , Figure 2 and Figure 4As shown in , by placing the polishing pad body 6 above the support table 3, the fixing frames 7 are symmetrically fixed on the left and right sides above the support table 3, an electric telescopic rod 10 is arranged on the inner side of the fixing frame 7, and a connecting rod 9 is arranged on the output end of the electric telescopic rod 10. A pressing plate 8 is arranged equidistantly below the connecting rod 9. When the electric telescopic rod 10 is opened, the output end of the electric telescopic rod 10 can push the pressing plate 8 and the connecting rod 9 to move downward, and push the pressing plate 8 to fit tightly with the polishing pad body 6 above the support table 3, so that the polishing pad body 6 is firmly fixed on the support table 3. Since a slide rail 17 is fixedly installed on the left side above the right side of the support base 1, a sliding block 16 is installed above the slide rail 17, and A controller 18 is installed on the upper right side of the slide rail 17. When the controller 18 is turned on, the slide block 16 can move left and right above the slide rail 17. In addition, a hydraulic rod 15 is installed at the lower middle part of the slide block 16. A support rod 12 and a blade 11 are installed at the output end of the hydraulic rod 15. That is, when the hydraulic rod 15 is turned on, the hydraulic rod 15 can push the blade 11 to contact the polishing pad body 6. Secondly, a motor 5 is installed on the top of the hydraulic rod 15. When the motor 5 is turned on, the hydraulic rod 15 can rotate with the blade 11, that is, the blade 11 can grind the polishing pad body 6. In this way, the polishing pad body 6 will not be offset in position during the dressing and grinding process, which will greatly improve the dressing and grinding accuracy of the polishing pad body 6.

[0028] like Figure 1 and Figure 2 As shown in the figure, the trimming and grinding of the polishing pad body 6 by the blade 11 can only be limited to the grinding of a part of the polishing pad body 6, that is, a threaded rod 2 is installed inside the lower part of the support platform 3, and the threaded rod 2 is located inside the upper left side of the support base 1. At the same time, limit rods 4 are installed on the left and right sides of the lower part of the support platform 3, and the rear end of the threaded rod 2 is connected to the motor 5. When the motor 5 is turned on, the motor 5 will cause the threaded rod 2 to start rotating, and the limit rod 4 engaged on the inner side of the lower part of the support platform 3 will limit the support platform 3, that is, the support platform 3 can move back and forth on the outer side of the threaded rod 2, that is, when the support platform 3 moves back and forth, the polishing pad body 6 can move back and forth with the support platform 3. The mechanical automatic movement of the polishing pad body 6 makes it convenient for the blade 11 to trim and grind the polishing pad body 6 in all directions, which greatly saves manpower;

[0029] like Figure 1 , Figure 2 and Figure 3As shown in the figure, a large amount of debris will be generated when the polishing pad body 6 is polished and trimmed by the blade 11, that is, a support rod 12 is installed above the blade 11, and a folding tube 13 is arranged above the support rod 12. The top of the folding tube 13 is fixedly connected to the fixed rod 14, that is, the folding tube 13 is located between the fixed rod 14 and the support rod 12, and the fixed rod 14 is installed on the left and right sides of the outer side of the hydraulic rod 15, and the support rod 12 is installed at the output end of the hydraulic rod 15. When the hydraulic rod 15 is opened, the output end of the hydraulic rod 15 can push the support rod 12 to move downward, that is, the folding tube 13 will change from a folded state to a stretched state. In this state, when the blade 11 under the support rod 12 contacts the polishing pad body 6 for grinding and trimming, since an absorption box 19 is installed on the upper right side of the fixed rod 14, an absorption tube 20 is connected to the upper right side of the absorption box 19, and an exhaust fan 21 is installed below the absorption tube 20, when the exhaust fan 21 is turned on, the absorption box 19 can absorb the debris when the blade 11 grinds the polishing pad body 6, and the debris can be transmitted to the debris box 22 on the right side of the exhaust fan 21 through the absorption tube 20 connected to the absorption box 19 for centralized collection. The collection of debris can not only make the operating environment clean but also protect the health of the operating workers.
