Abstract
Description
Technical Field
[0001] The utility model relates to crucible maintenance equipment, and more specifically, to a crucible cleaning device. Background Art
[0002] Boron nitride crucibles are often used as kiln tools for loading ceramic substrates during the sintering process because of their excellent properties, such as high purity and high temperature resistance. However, during the long-term use of the crucible, crystallized plates will form on its surface, and the porous surface is very easy to adsorb volatile substances, affecting its performance. Therefore, the crucible needs to be cleaned regularly to ensure its clean surface and stable performance. However, there is no relevant equipment available for the current crucible cleaning process, which mainly relies on manual sandpaper polishing.
[0003] During the crucible cleaning process, the boron nitride crucible is held by hand and its surface is polished with sandpaper of a certain mesh. However, the boron nitride crucible itself has low strength, and uneven force is easily applied during the hand-held process, resulting in problems such as missing corners and breakage of the crucible, causing unnecessary losses; in addition, during the manual sandpaper polishing process, the effect of removing the plate-like materials on the crucible surface is poor, time-consuming and labor-intensive, and the removal is not thorough. At the same time, there is uneven force application, resulting in uneven polishing of the crucible surface. The surface of the polished crucible is uneven, which has an adverse effect on the firing of the product. Utility Model Content

DETAILED DESCRIPTION
[0024] 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.
[0025] See also Figures 1 to 4 A crucible cleaning device includes an adsorption box 100 and a polishing mechanism 200. The interior of the adsorption box 100 is a hollow structure to form an adsorption chamber 140. Adsorption holes 150 are provided on the surface of the adsorption box 100. The adsorption holes 150 separate the adsorption chamber 140 from the outside. At the same time, the adsorption box 100 is connected to a vacuum pump assembly through a pipe 130, thereby generating a negative pressure in the adsorption chamber 140. When the crucible is placed on the surface of the adsorption box 100, the crucible can be adsorbed through the adsorption holes 150, thereby achieving effective and uniform fixation of the crucible. This avoids uneven force application during the hand-held process, which may cause the crucible to break.
[0026] The adsorption box 100 is a cubic structure, and a positioning plate is arranged on the adsorption box 100, and the positioning plate includes a first positioning plate 110 and a second positioning plate 120. The first positioning plate 110 and the second positioning plate 120 are arranged with edges on two adjacent sides of the adsorption box 100, so that the first positioning plate 110 and the second positioning plate 120 are perpendicular to each other. The crucible placed on the adsorption box 100 is positioned by fitting with the first positioning plate 110 and the second positioning plate 120, thereby ensuring the stability of the crucible when placed.
[0027] There are multiple adsorption holes 150, which form a matrix structure. The distance between two adjacent adsorption holes 150 in each row is equal, and the distance between two adjacent adsorption holes 150 in each column is equal. In this way, the uniformity of the distribution of the adsorption holes 150 can be ensured, so that the crucible can be uniformly stressed everywhere, thereby preventing the crucible from being damaged due to uneven stress.
[0028] The polishing mechanism 200 includes a housing 210, in which a driving assembly is disposed, and the driving assembly is connected to an eccentric disk so that the eccentric disk can vibrate. The Chinese invention patent with publication number CN109848808A and the name of pneumatic grinder has disclosed the detailed structure of the driving assembly, the way the driving assembly is installed in the housing 210, and the way the driving assembly is connected to the eccentric disk, so it is not repeated here.
[0029] The eccentric seat 300 includes a main body 310 and a fixing ring 320 sleeved outside the main body 310. Sandpaper is clamped between the main body 310 and the fixing ring 320 so that the sandpaper is fixed to the bottom of the eccentric seat 300. At the same time, a mounting groove 410 is provided on the main body 310, and a mounting hole 420 corresponding to the position of the mounting groove 410 is provided on the fixing ring 320. The main body 310 is connected to the fixing ring 320 by inserting a fastener 400 into the mounting groove 410 through the mounting hole 420, so as to keep the sandpaper clamped stably. At the same time, by disassembling the fixing ring 320, the sandpaper can be replaced to use sandpaper of different meshes for polishing to correspond to the different particle sizes of the processed surface.
[0030] The edge of the lower end surface of the main body 310 is provided with a first embedding groove 311. When the sandpaper is installed, the sandpaper covers the lower end surface of the main body 310, and the edge of the sandpaper is embedded in the first embedding groove 311. At this time, the fixing ring 320 is sleeved on the main body 310. The fixing ring 320 is provided with a protrusion 321 extending toward the first embedding groove 311. The protrusion 321 partially extends into the first embedding groove 311, so that the protrusion 321 squeezes the edge of the sandpaper and fixes the sandpaper. The protrusion 321 is provided with a protrusion 322 protruding toward the main body 310. The protrusion 322 is located at the opening of the first embedding groove. The protrusion 322 can further squeeze the sandpaper, thereby further ensuring the stability of the sandpaper installation and preventing it from falling off due to vibration.
[0031] The fixing ring 320 is provided with a second embedding groove 323 on one side facing the main body 310, and the second embedding groove 323 is at least partially connected to the first embedding groove 311. The edge of the sandpaper can be embedded in the second embedding groove 323 after being embedded in the first embedding groove. At the same time, the first embedding groove 311 and the second embedding groove 323 are respectively provided on the main body 310 and the fixing ring 320, and the two form a labyrinth structure and clamp the sandpaper therein, further improving the stability of the sandpaper installation.
