Description

Technical Field

[0001] This invention relates to the field of stainless steel watch strap processing technology, specifically to an automatic polishing device for stainless steel watch straps. Background Technology

[0002] As a fastening component of a watch, the watch strap comes into direct contact with the human body. To avoid scratching the skin, its outer surface needs to be kept smooth. Furthermore, for decorative purposes, polishing has become an essential step in watch strap production. There are many types of watch straps, including stainless steel and silicone straps. Stainless steel watch straps are typically polished manually by hand, which is inefficient and results in inconsistent smoothness, leading to a high defect rate. Therefore, stainless steel watch strap polishing equipment has emerged on the market.

[0003] Currently, most stainless steel watch band polishing equipment on the market is designed to be semi-automatic. It requires manual placement of the stainless steel watch band onto a polishing fixture, which is then moved to a robot. The robot grips the fixture and moves it to the polishing fixture for polishing. During operation, the polishing wheel needs to be waxed and repaired. Manual waxing is unsafe and requires machine downtime for safety reasons, significantly reducing the efficiency of stainless steel watch band polishing. Furthermore, existing stainless steel watch band polishing equipment directly releases waste fumes into the workshop air during polishing, resulting in high levels of environmental pollution. Therefore, the inventor has designed an automatic stainless steel watch band polishing device. Summary of the Invention

The grinding block 5969 is fixedly mounted on the grinding block mounting seat 5968, and the grinding block 5969 is provided with grinding teeth 59612 for grinding the grinding wheel 585.

[0053] Please see Figure 13The automatic waxing assembly 597 in the figure includes a fourth lead screw fixing plate 5971 fixedly mounted on a Y-axis fixing plate 595. A fourth lead screw 5972 is provided on the fourth lead screw 5971 along its length. A fourth internal threaded sleeve 5973 is sleeved on the fourth lead screw 5972. A waxing sliding plate 5974 is fixedly mounted on the fourth internal threaded sleeve 5973. A fifth servo motor 5975 is fixedly mounted on the waxing sliding plate 5974. The output end of the fifth servo motor 5975 is connected to a fifth lead screw 5976. A fifth lead screw 5976 is sleeved on the fifth lead screw 5976. The fifth internal threaded sliding sleeve 5977 has a wax pusher 5978 fixedly installed on it. The waxing sliding plate 5974 is also provided with a wax clamping sleeve 5979, on which a wax block 59710 is installed. The wax block 59710 is in contact with the wax pusher 5978. The wax clamping sleeve 5979 has a first annular hole 59711 for the wax pusher 5978 to move, and a wax cover plate 59712 is provided on the wax clamping sleeve 5979. The fourth lead screw fixing plate 5971 is also provided with a sixth servo motor 59713 for driving the fourth lead screw 5972 to rotate.

[0054] Please refer to it again. Figure 12 and Figure 13When the aforementioned grinding wheel 585 needs repair during operation, the fourth servo motor 59610 drives the third lead screw 5965 to rotate, thereby moving the third internal threaded sleeve 5966 along the length of the third lead screw 5965. Since a grinding connecting plate 5967 is fixedly installed on the third internal threaded sleeve 5966, this can drive the grinding block mounting base 5968 connected to the grinding connecting plate 5967 and the grinding block 5969 installed on the grinding block mounting base 5968 to move down and contact the grinding wheel 585. The grinding teeth 59612 on the grinding block 5969 repair the grinding wheel 585. After the repair is completed, the fourth servo motor 59610 drives the grinding block 5969 to reset. When the grinding wheel 585 needs waxing, the sixth servo motor 59713 drives the fourth lead screw 5972 to rotate, and drives the fourth internal threaded sleeve 5973 along the length of the fourth lead screw 5965. The waxing sliding plate 5974 is fixedly installed on the fourth internal threaded sleeve 5973, which further drives the waxing sliding plate 5974 to move. A fifth servo motor 5975 is set on the waxing sliding plate 5974. The output end of the fifth servo motor 5975 is connected to the fifth lead screw 5976. The fifth internal threaded sleeve 5977 is sleeved on the fifth lead screw 5976. When the fifth servo motor 5975 drives the fifth lead screw 5976 to rotate, it can drive the fifth internal threaded sleeve 5977 to move along the length direction of the fifth lead screw 5976. In turn, it can drive the wax pusher 5978 connected to the fifth internal threaded sleeve 5977 to move. When the wax pusher 5978 moves towards the grinding wheel 585, the wax pusher 5978 pushes the wax block 59710 to contact the grinding wheel 585, completing the waxing process. The whole process does not require stopping the machine, which greatly improves the processing efficiency.

[0055] Please see Figure 14 The waste collection hood 510 in the figure has a second annular hole 511 on its side wall for the aforementioned rotating shaft 583 to pass through, and a waste gas collection hole 512 is provided on the waste gas collection hood 510. A screen 513 is embedded in the waste gas collection hole 512. In specific implementation, the waste gas collection hole 512 is connected to a suction fan (not shown in the figure), and the other end of the suction fan is connected to a waste gas treatment device (not shown in the figure). The purpose of this design is to prevent the waste gas generated during the polishing process of the aforementioned grinding mechanism 58 from polluting the air.
