Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Embodiments of the present invention are written in a progressive manner.
As shown in fig. 1 to fig. 2, a centrifugal tool provided in an embodiment of the present invention includes a rotating sleeve 1, where the rotating sleeve 1 is used for cooperating with a rotation driving mechanism; the supporting plate 2 is fixedly connected with the rotating sleeve 1, and a plurality of workpiece positioning pieces 3 are fixed on the supporting plate 2; the workpiece positioning piece 3 is used for restricting the movement of the workpiece, so that the workpiece is driven by the supporting plate 2 to rotate together with the supporting plate 2; the workpiece positioning element 3 comprises a first positioning structure 31 and a second positioning structure 32; the workpiece is a hollow column, and the side surface of the hollow column is in contact with the supporting plate 2; the first positioning structure 31 is a U-shaped groove, and one end of the hollow column is positioned inside the U-shaped groove; the second positioning structure 32 is used for being matched with the first positioning structure 31, so that the hollow column is always positioned between the U-shaped groove and the second positioning structure 32 in the rotating process.
According to the centrifugal tool, the rotary sleeve 1 matched with the rotary driving mechanism is arranged, and the supporting plate 2 fixed with the plurality of station positioning pieces is fixedly connected with the rotary sleeve 1, so that the rotary sleeve 1 can drive the supporting plate 2 to rotate under the driving of the rotary driving mechanism, the workpiece is driven to rotate through the combined action of the supporting plate 2 and the workpiece positioning piece 3, and redundant liquid on the surface of the workpiece is thrown out through centrifugal force. In the rotating process, under the constraint of the workpiece positioning piece 3, the workpiece to be processed can not move close to or far away from the rotating center. Since the workpiece positioning element 3 comprises the first positioning structure 31 and the second positioning structure 32; the first positioning structure 31 is a U-shaped groove, and one end of the hollow column is placed in the U-shaped groove; meanwhile, the second positioning structure 32 is matched with the first positioning structure 31, the constraint effect on the hollow column is realized under the combined action, and the hollow column is ensured to be always positioned between the U-shaped groove and the second positioning structure 32 in the rotating process. When the hollow column passes through the terminal surface and contacts with backup pad 2, because hollow column axial length is long, at rotatory in-process, the unnecessary dip-coating liquid of adhering to in the hollow column inside can't throw away, can lead to the inside volume of remaining of hollow column many, and work piece surface coating is uneven. Therefore, the side surface of the hollow column is contacted with the support plate 2 in the placing process, so that residual liquid in the hollow column is easier to discharge. So, not only make the contact of single work piece and dip-coating liquid more abundant, moreover in centrifugal process, because work piece setting element 3's limiting action, treat that the work piece can not produce violent collision each other, also can not pile up each other, the unnecessary dip-coating liquid in work piece surface is discharged more easily. The centrifugal tool and the dip-coating equipment provided by the invention can effectively avoid the accumulation of workpieces to be processed, increase the contact between dip-coating liquid and the workpieces, prevent the workpieces from being adhered, optimize the coating effect and ensure that the thickness of the coating on the surface of the workpiece is uniform.
The second positioning structure 32 in the embodiment of the present invention may have various forms, for example, a slot disposed at an end of the hollow column far from the U-shaped slot; or the baffle plates are arranged at two sides of the hollow column; and may be a stopper rod or the like provided on both sides of the hollow column.
In order to simplify the second positioning structure 32, it is preferable that the second positioning structure 32 includes a first positioning portion 321, and an end of the hollow column away from the U-shaped groove is located between the rotating sleeve 1 and the first positioning portion 321. Like this, first location portion 321, rotatory sleeve 1 and U type groove form a location space jointly, place hollow column in this location space and can realize the constraint effect to hollow column.
In order to further save space, so that more workpiece positioning elements 3 can be arranged on the supporting plate 2, and more hollow columns can be dip-coated in a certain time, as one of the embodiments of the present invention, a plurality of workpiece positioning elements 3 can be arranged around the rotating sleeve 1; the first positioning portions 321 and the U-shaped grooves are uniformly distributed around the circumference of the rotating sleeve 1. One end of the hollow column is located between the rotating sleeve 1 and the first positioning portion 321, and the other end of the hollow column is correspondingly placed inside a U-shaped groove. Therefore, the installation density of the workpiece positioning piece 3 can be greatly improved, and the processing efficiency is improved. In addition, in order to further increase the processing efficiency, a plurality of hollow columns can be stacked in one workpiece positioning element 3, and the hollow columns are in contact with each other through the side surfaces. Simultaneously, in order to further guarantee the intensity of centrifugal frock, can set up the strengthening rib between each U type groove, the strengthening rib connects into each U type groove and becomes a whole, is favorable to guaranteeing the wholeness of centrifugal frock, makes its intensity higher.
Preferably, in the constrained space formed by the workpiece positioning element 3, two hollow columns are positioned in two adjacent constrained spaces, wherein the central axis of one hollow column can penetrate through the side surface of the other hollow column. Therefore, during the rotation process, one of the two hollow columns positioned in the two adjacent constraint spaces can cooperate with the U-shaped groove of the other hollow column to prevent the hollow column from moving along the axis direction of the hollow column during the rotation process.
As an embodiment of the present invention, the U-shaped groove may include a second positioning portion 311, a third positioning portion 312, and a fourth positioning portion 313; second location portion 311 and third location portion 312 form two side portions of a U-shaped groove, and fourth location portion 313 is connected with second location portion 311 and third location portion 312 to form a bottom portion of the U-shaped groove. In order to ensure that the hollow column can stably rotate along with the support plate 2 in the centrifugal process, the mutual collision between the short column piece and the support plate 2 is reduced. The distance between the second positioning portion 311 and the third positioning portion 312 is equal to the diameter of the cross section of one end of the hollow column. Thus, the second positioning portion 311 and the third positioning portion 312 can ensure that the hollow column does not shake during moving or rotating. Therefore, a plurality of hollow columns can be placed in one workpiece positioning piece 3, mutual interference among the hollow columns can be avoided to the greatest extent, the contact area of a workpiece and dip-coating liquid is increased, the redundant dip-coating liquid on the inner wall of each hollow column is smoothly discharged, and the surface coating of each hollow column is more uniform. Preferably, the distance between the first positioning portion 321 and the rotating sleeve 1 is equal to the diameter of the cross section of the other end of the hollow column away from the U-shaped groove. The stability of the hollow column in the rotation process is further improved.
In the embodiment of the present invention, the first positioning portion 321, the second positioning portion 311, the third positioning portion 312, and the fourth positioning portion 313 may be positioning plates, positioning columns, or other irregular structures which have irregular shapes but can play a role of blocking. When the first positioning portion 321, the second positioning portion 311, and the third positioning portion 312 are positioning posts, since the positioning posts are in line contact with the nuts, each hollow post can be fully contacted with the dip-coating liquid in the dip-coating process, and meanwhile, the excess dip-coating liquid on the surface of the hollow post is more easily discharged in the centrifugal process. Of course, the positioning column may be a circular column, a square column, a solid column, a hollow column, or the like.
In order to satisfy the light weight design of the centrifugal tool, one or more of the first positioning portion 321, the second positioning portion 311, and the third positioning portion 312 are preferably of a hollow column structure, and a liquid outlet is provided at the lower end of the hollow column. The fourth positioning portion 313 is preferably a connection plate on which a drain hole is formed. The liquid outlet is arranged to prevent the dip coating liquid filled in the hollow column from being discharged after the centrifugal tool is immersed in the dip coating liquid. The arrangement of the liquid discharge holes is to avoid that redundant liquid thrown out from the surface of the hollow column is accumulated on the connecting plate in the rotating process to influence the centrifugal effect.
In order to further exhaust the liquid inside the hollow column, it is preferable that the connection between the hollow column and the support plate 2 is a through structure, so that when the centrifugal tool leaves the liquid surface, the liquid filled in the hollow column is automatically exhausted from the bottom end of the hollow column through the support plate 2 under the action of the gravity of the liquid, and little residue is left.
Because the redundant liquid on the surface of the workpiece is thrown away from the surface of the workpiece through centrifugal force, the parts of the centrifugal tool can rotate at high speed more stably in the centrifugal process. Preferably, the workpiece positioning elements 3 can be uniformly distributed on the surface of the supporting plate 2, so that the center of gravity of the centrifugal tool is located at the center of the rotating sleeve 1, and the mass distribution of the rotating sleeve 1 in the whole circumferential direction is kept uniform.
In practical application, the shape of the rotating sleeve 1 can be varied, as long as it can be matched with the rotating driving mechanism and can rotate under the driving of the rotating driving mechanism. For example, the rotating sleeve 1 in the embodiment of the present invention may be a straight cylinder type, a trumpet shape, a regular polygonal column, or the like. However, preferably, the rotating sleeve 1 in the present invention may be a conical cylinder, when the rotating sleeve 1 is a conical cylinder, the rotating sleeve 1 contacts with the rotating head of the rotation driving mechanism through an inclined plane, so that under the action of gravity, a first component force vertically downward and a second component force horizontally pointing to the rotation center are generated between the side wall of the rotating sleeve 1 and the rotating head, and the two component forces can ensure that the rotating sleeve 1 and the rotating head are tightly fitted during the centrifugation process, so that the centrifugation tool can rotate at a high speed more stably.
In addition, because the centrifugal tool is gradually immersed below the surface of the dip-coating liquid from a high position, the centrifugal tool is inevitably subjected to resistance from the liquid in the process of immersing the centrifugal tool into the liquid, and certain resistance is generated to the immersion of the centrifugal tool into the dip-coating liquid due to the pressure generated by the air remained in the rotary sleeve 1.
In order to reduce the resistance to the immersion of the centrifugal tool, it is preferable to provide at least one first through hole 11 in the rotating sleeve 1 and/or at least one second through hole 21 in the support plate 2. Of course, the design of the first through hole 11 and the second through hole 21 not only enables the tool to enter the liquid more smoothly, but also plays a role in reducing weight, meets the requirement of lightweight centrifugal tool, and saves raw materials.
When only one first through hole 11 is provided in the rotating sleeve 1, the first through hole 11 is preferably provided at the top of the rotating sleeve 1.
Further, in order to make the mass distribution of the whole tool uniform in the circumferential direction of the rotation, it is preferable that a plurality of first through holes 11 are provided and the first through holes 11 are uniformly distributed on the rotating sleeve 1, and/or a plurality of second through holes 21 are provided and the second through holes 21 are uniformly distributed on the supporting plate 2.
Because in the course of working, hold the rotatory sleeve 1 of work piece and need be held and shift by elevating system with adding, for the transfer of convenient rotatory sleeve 1, can set up on the rotatory sleeve 1 be used for with elevating system complex hoist and mount portion 4, for making rotatory sleeve 1 more stable at the transfer in-process, as the preferred, can set up hoist and mount portion 4 at the top of rotatory sleeve 1.
The invention also provides dip-coating equipment which comprises a material cylinder for containing dip-coating liquid, a rotary driving mechanism for centrifugation and any one of the centrifugal tools.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
