Description

Technical Field

[0001] This utility model belongs to the field of water drill production technology, and specifically relates to a water drill end face grinding and polishing device. Background Technology

[0002] Flat-bottomed diamonds are a common name for jewelry made primarily of crystal glass. They are jewelry accessories made by cutting glass into diamond facets. This material is popular because it is relatively inexpensive and has a dazzling diamond-like visual effect.

[0003] The traditional flat-bottom drilling and polishing process generally involves: loading material, gluing, grinding, polishing, changing the surface, grinding again, polishing again, and unloading. The grinding and polishing process in the market often uses surface grinding and polishing methods.

[0004] For example, application number CN200710069274.6 discloses a method for grinding and polishing the end face of a water-drill, including fabric preparation, vacuum forming, end face grinding and polishing, and unpacking. The corresponding equipment can be found in patents with application numbers CN202211210838.4 or CN201120425578.3.

[0005] Rhinestones are evenly arranged and fixed on the surface of a blister pack. The plastic layer of the blister pack covers the face of the rhinestones, exposing the bottom, for a reflective coating. Because hundreds or even thousands of rhinestones can be arranged on a single blister pack, processing efficiency is greatly improved, eliminating the need for multiple rhinestone arrangements and facilitating circulation within the workshop. The blister pack method allows for precise control of the rhinestone coating position, ensuring product quality and simplifying processing steps. However, blister packs inevitably have edges, which increase the waste of reflective coating material. This is particularly noticeable when using chemical silver plating, where the entire blister pack is immersed in the silver plating solution, resulting in silver coating on both sides. Excessive edge area increases material waste; furthermore, the protruding edge reduces the ease of handling and storage. Therefore, the protruding edge needs to be cut off to create a circular blister pack.

[0006] For example, patent application number CN201220259778.0 discloses a rhinestone blister tray trimming machine, including a frame, a rotating shaft vertically mounted on the frame, the rotating shaft being connected to a motor drive, a positioning plate for mounting the blister tray mounted on the upper end of the rotating shaft, a pressure plate above the positioning plate, the pressure plate being mounted on a lifting seat via bearings, a blade holder mounted on the lifting seat, a blade mounted on the blade holder, the lifting seat being vertically slidably connected to the frame and connected to the moving end of a cylinder. A bracket is mounted on the frame, and a vertical guide rod is mounted on the bracket, the lifting seat sliding vertically along the guide rod. The blade holder is mounted on the lifting seat in a movable and adjustable manner. The positioning plate has a circular boss capable of housing the blister tray, and the top surface of the circular boss has an annular groove A for inserting the blade tip.

[0007] In existing technology, end face grinding and polishing and edge trimming are performed separately by two operators in different positions; this not only requires the transfer of the blister pack, but also consumes more manpower. Utility Model Content
