Description

Technical Field

[0001] The utility model relates to a tool for producing ceramic shells, in particular to a tool for drying ceramic shells. Background Art

[0002] Ceramic housing is also called ceramic package housing. It has the characteristics of high insulation performance, high thermal conductivity, corrosion resistance, and high strength. It is composed of a multi-layer ceramic structure, which can realize a multi-layer circuit structure and meet the market demand for electronic miniaturization. Ceramic housing plays a vital role in the field of electronic packaging.

[0003] Ceramic shells inevitably need to be cut during the production process. The powder produced by cutting easily adheres to the surface of the ceramic shell, affecting its insulation and pressure resistance performance, and needs to be cleaned and dried. At present, there are two main ways to dry ceramic shells. One is to use hot air to dry and then put them in an oven to dry. The other is to use a centrifuge to dry. Among them, the centrifuge drying requires the use of tooling to prevent the ceramic shell from being damaged by the centrifugal force. The existing centrifugal drying tooling slot only has a receiving slot for placing workpieces. Although the receiving slot is provided with a water filter hole, the receiving slot is fixed. When in use, the workpiece will be close to the side wall of the receiving slot, which makes it difficult for the water in the corresponding position to be thrown out, affecting the drying efficiency.

[0004] In view of this, the applicant conducted an in-depth study on the structure of the ceramic shell spin-drying tooling, which resulted in this case. Utility Model Content

[0005] The utility model aims to provide a ceramic shell drying tool with relatively high drying efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A ceramic shell spin-drying tool comprises a rotating disk, on which a plurality of through holes are arranged around the axis of the rotating disk, the cross-section of the through holes is waist-shaped, and the cross-sectional length or cross-sectional width of the through holes gradually increases from top to bottom, and each of the through holes is interspersed with a drain seat for placing the ceramic shell.

[0008] As an improvement of the present invention, the drain seat includes a waist-shaped column inserted in the corresponding through-hole and a positioning ring integrally connected to the upper part of the outer peripheral wall of the waist-shaped column, the positioning ring abuts against the upper end surface of the rotating disk, an elliptical blind hole is provided at the upper end of the waist-shaped column, and a drainage groove connected to the elliptical blind hole is provided at the lower end, the long diameter direction of the elliptical blind hole, the length direction of the drainage groove and the length direction of the waist-shaped column are the same, the groove width of the drainage groove is smaller than the short diameter length of the elliptical blind hole, and the two ends of the drainage groove in the length direction pass through the outer side wall of the waist-shaped column, and a drainage window connected to the elliptical blind hole is also provided on the outer side wall of the waist-shaped column.

[0009] As an improvement of the utility model, the bottom of the drainage groove and the lower end surface of the positioning ring are located on the same plane.

[0010] As an improvement of the present invention, chamfers are formed between the two ends of the bottom surface of the elliptical blind hole in the length direction and the side walls of the elliptical blind hole.

[0011] As an improvement of the utility model, there are two drainage windows, which are respectively located on both sides of the drainage groove, and both ends of each drainage window in the length direction extend to the arc-shaped outer side wall of the waist-shaped column.

[0012] As an improvement of the utility model, the lower side wall of each drainage window is arranged flush with the bottom surface of the elliptical blind hole.

[0013] As an improvement of the utility model, both ends of each drainage window in the length direction are arranged flush with both ends of the elliptical blind hole in the length direction in a one-to-one manner.

[0014] As an improvement of the utility model, the lower end surface of the rotating disk is integrally connected with a support column coaxially arranged with the rotating disk, and a positioning groove is formed at the lower end of the support column.

[0015] As an improvement of the utility model, a through hole coaxially arranged with the support column is provided on the support column.

[0016] As an improvement of the present utility model, the rotating disk is a plastic steel disk, the drain seat is a plastic steel seat, and a copper sleeve is embedded in the through hole.

[0017] By adopting the above scheme, the utility model has the following beneficial effects:

[0018] 1. Since the cross-sectional length or width of the perforation gradually increases from top to bottom, forming a structure similar to a conical hole, the drain seat can swing under the action of centrifugal force when in use, so that the water adhering to the ceramic shell can be better thrown out, and the drying efficiency is relatively high.

[0019] 2. The drain seat structure adopted by the utility model has a relatively small contact surface between the ceramic shell and the drain seat, which helps to reduce residual water and further improve the drying efficiency.

[0020] 3. Compared with the technical solution of drying with hot air and then putting it in an oven for drying, the technical solution of drying with a centrifuge is less likely to leave water stains on the surface of the ceramic shell. Since the drain seat used in the utility model has good drainage capacity, it helps to further reduce the water stains on the surface of the ceramic shell and improve the product qualification rate.

[0034] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] like Figure 1-Figure 6As shown, this embodiment provides a ceramic shell drying tool, including a horizontally arranged rotating disk 10, the lower end surface of the rotating disk 10 is integrally connected with a support column 11 arranged coaxially with the rotating disk 10, and the lower end of the support column 11 is provided with a positioning groove 12 that cooperates with the centrifuge, so that the rotating disk 10 can be driven to rotate by the rotating shaft of the centrifuge, and the support column 11 is provided with a through hole 13 arranged coaxially with the support column 11 for inserting the rotating shaft of the centrifuge. It should be noted that the above-mentioned centrifuge with a rotating shaft is a conventional centrifuge, which can be directly purchased on the market and is not a part of the ceramic shell drying tool provided in this embodiment.

[0036] The rotating disk 10 is also provided with a plurality of through holes 14 evenly distributed around the axis of the rotating disk 10. The cross-section of the through hole 14 is waist-shaped, and the cross-sectional length or cross-sectional width of the through hole 14 gradually increases from top to bottom, forming a structure similar to a conical hole. That is, the through hole is a waist-shaped hole, and the outline size (or outer diameter) of the waist-shaped hole gradually increases along its depth direction, which can provide a swing space for the drain seat 20 to be mentioned below.

[0037] Since metal materials are relatively hard, they can easily scratch the ceramic shell or cause ceramic cracks when in contact with the ceramic shell. Preferably, the rotating disk 10 is a plastic steel disk and the drain seat 20 is a plastic steel seat. This helps to avoid scratches or cracks on the ceramic shell. Of course, the rotating disk 10 and the drain seat 20 can also be made of other non-metallic materials such as plastic. A copper sleeve (not shown in the figure) is embedded in the through hole 13. This can reduce the dead weight of the rotating disk 10 while improving the wear resistance of the rotating disk 10, thereby increasing its service life.

[0038] A drain seat 20 for placing a ceramic shell is inserted in each through hole 14 , and the drain seat 20 includes a waist-shaped column 21 inserted in the corresponding through hole 14 and a positioning ring 22 integrally connected to the upper part of the outer peripheral wall of the waist-shaped column 21 , wherein the positioning ring 22 abuts against the upper end surface of the rotating disk 10 . The cross-section of the waist-shaped column 21 is waist-shaped, and it has two planar side walls arranged parallel to each other and two arc-shaped outer walls respectively connected between the two planar outer walls. An elliptical blind hole 23 is provided at the upper end of the waist-shaped column 21, and a drainage groove 24 connected to the elliptical blind hole 23 is provided at the lower end. The elliptical blind hole 23 is a straight blind hole with an elliptical cross-section, which is used to place a ceramic shell. The long diameter (i.e., the long diameter of the cross-sectional ellipse), short diameter (i.e., the short diameter of the cross-sectional ellipse) and depth of the elliptical blind hole 23 need to be set according to the size of the ceramic shell to be dried. In this way, the side of the ceramic shell (usually a rectangular parallelepiped) will not contact the side wall of the elliptical blind hole 23, which greatly reduces the contact area between the two and is conducive to throwing out the water on the side wall of the ceramic shell.

[0039] Preferably, chamfers are formed between the two ends of the bottom surface of the elliptical blind hole 23 in the length direction and the side walls of the elliptical blind hole 23, and the chamfers can be rounded or chamfered. When in use, the two ends of the ceramic shell are respectively pressed against the two chamfers one by one, so that the lower end surface of the ceramic shell can be suspended, further reducing the contact area between the ceramic shell and the drain seat 20, thereby achieving rapid drying.

[0040] The long diameter direction of the elliptical blind hole 23, the length direction of the drainage groove 24 and the length direction of the waist-shaped column 21 (i.e., the length direction of the cross section of the waist-shaped column 21) are the same, and are all arranged perpendicular to the radial direction of the rotating disk 10. The groove width of the drainage groove 24 is smaller than the short diameter length of the elliptical blind hole 23 to prevent the ceramic shell placed in the elliptical blind hole 23 from passing through the drainage groove 24. The two ends of the drainage groove 24 in the length direction penetrate the outer wall of the waist-shaped column 21, and the groove bottom of the drainage groove 24 and the lower end surface of the positioning ring 22 are located on the same plane, so that better drainage can be achieved and water can be thrown out of the drain seat 20 efficiently.

[0041] In addition, a drainage window 25 connected to the elliptical blind hole 23 is provided on the outer wall of the waist-shaped column 21. The location and number of the drainage windows 25 can be determined according to actual needs. In the present embodiment, there are two drainage windows 25, which are respectively located on both sides of the drainage groove 24. Both ends of the drainage windows 25 in the length direction extend to the arc-shaped outer wall of the waist-shaped column 21. In this way, a concave notch can be formed on the two planar outer walls of the waist-shaped column 21. When the centrifugal force is too large and causes the drain seat 20 and the rotating disk 10 to move relative to each other, the notch will be stuck in the upper mouth of the corresponding perforation 14, preventing the drain seat 20 and the rotating disk 10 from continuing to slide relative to each other, thereby preventing the drain seat 20 from being thrown out of the rotating disk 10.

[0042] Preferably, the lower side wall of each drainage window 25 is arranged flush with the bottom surface of the elliptical blind hole 23, and both ends of each drainage window 25 in the length direction are arranged flush with both ends of the elliptical blind hole 23 in the length direction, so that water can be thrown out better.

[0043] When in use, the ceramic shell is placed in the elliptical blind hole 23 of each drain seat 20, and each drain seat 20 is placed in the corresponding through hole 14, then the through hole 13 of the selection turntable 10 is sleeved on the rotating shaft of the centrifuge, and the positioning pin of the centrifuge is embedded in the positioning groove 12, and then the centrifuge can be started to spin water.

[0044] The present invention is described in detail above with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various equivalent substitutions for the present invention based on the prior art, which all belong to the protection scope of the present invention.
