JPH04250975A - Barrel polishing jig for contact lens supporting member - Google Patents

Abstract

PURPOSE:To promote a deburring process and facilitate separation from the contents of a barrel vessel by using a jig connecting a plurality of contact lens supporting members. CONSTITUTION:A plurality of contact lens supporting members 4 are formed into one body with an adhesive tape 5, received in a barrel vessel 1 together with the contents 2 of the barrel, and stirred for deburring. Further, a pincette and the like is used for taking out the supporting members 4 to take out several pieces of the supporting members in one body at a time.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig used for barrel polishing an intraocular lens support member.

0002

2. Description of the Related Art In recent years, intraocular lenses having an integral support member have become widely used. This support member has a loop shape with a length of about several mm, and both ends are cut off with a razor or the like after molding. Therefore, it becomes necessary to deburr both ends. In order to improve work efficiency, barrel polishing is generally used for this deburring process.

0003

[Problems to be Solved by the Invention] However, when deburring the tip of the support member by barrel polishing, the support member is very light and fine, so it is not well stirred in the barrel, resulting in long processing times. had become necessary.

Furthermore, in order to separate the support members from the contents of the barrel, the support members must be extracted one by one with tweezers, which has the disadvantage of poor working efficiency.

The present invention has been devised in view of the above-mentioned drawbacks, and provides a barrel for an intraocular lens support member in which the support member is well stirred within the barrel, shortens the barrel polishing time, and is easily separated from the contents of the barrel. The technical challenge is to provide a polishing jig.

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a jig for deburring intraocular lens support members using a barrel. It is characterized by making it easy to take out and promoting the stirring action of the barrel.

[0007] Furthermore, the connecting jig is characterized in that it is an adhesive tape.

[0008]

[Function] According to the present invention, with the above structure, the jig increases the contact area with the contents during stirring, so that sufficient stirring is achieved. Furthermore, since a large number of support members are integrated by the jig, extraction with tweezers becomes easy.

Embodiments Below, embodiments of the present invention will be explained based on the drawings. FIG. 1 is a schematic explanatory diagram showing a barrel polishing apparatus of this embodiment.

In FIG. 1, reference numeral 1 denotes a barrel container, which has a cylindrical shape with a bottom and a diameter of 120 mm. Note that the lid portion is omitted in the drawing. The inner circumferential surface of this barrel container 1 has a hexagonal cross section and holds granular contents 2 therein.

The contents 2 have a particle size of 1 to 3 mm, and are stirred by the rotation of the barrel container 1 having a hexagonal inner circumferential surface. Two drive rods 3 are used to rotate the barrel container 1, and the barrel container 1 is placed on the drive rods 3 that rotate in parallel and in the same direction.

The intraocular lens support member 4 to be deburred by the above device has a loop shape with a thickness of 0.15 mm and a length of several mm, and is made of polypropylene. This support member 4 is formed into a loop shape using a jig and then cut at both ends with a razor, so that both ends have burrs.

Next, an adhesive tape is used to connect the supporting members 4.
Step 5 will be explained. FIG. 2 is a diagram showing how seven supporting members 4 are adhered to the adhesive tape 5. However, the number of supporting members 4 is not particularly limited, and may be appropriately selected depending on the size of the barrel container 1 and the like. Furthermore, as shown in FIG. 3, which is a side view of FIG. 2, in this embodiment, a structure is adopted in which two adhesive tapes are used to sandwich and fix the tape, but the present invention is not limited to this. Of course, it may also be used.

As mentioned above, the adhesive tape 5 is attached to the support member 4.
By integrally adhering the adhesive tape 5, the adhesive tape 5 acts as a sail, and when mixed with the contents 2 in the barrel container 1 and stirred, this stirring is promoted.

Note that in the bonding method shown in FIG. 2, one end of the support member 4 is not deburred, but this one end is bonded to the lens portion, so there is no problem. Furthermore, depending on the bonding method, both ends can be deburred, and it goes without saying that this is also included in the present invention.

Next, the procedure of the deburring process using the above-mentioned adhesive tape will be explained. The support member 4 to be deburred by the above-mentioned device is formed into a loop shape using a jig and then cut at both ends with a razor or the like, so that both ends have burrs.

First, several supporting members 4 are set on the adhesive surface of adhesive tape 5 with a length of several cm, and the supporting members 4 are fixed so as to be sandwiched between adhesive tapes 5 of the same size ( Figure 2, Figure 3
).

The support member group thus produced is placed in the barrel container 1 containing the contents 2, and the lid is closed. Then, this barrel container 1 is placed horizontally on two drive rods 3. When the two drive rods 3 are rotated in the same direction by a drive source (not shown), the barrel container 1 is also rotated (FIG. 1). At this time, the support member 4 is sufficiently stirred and burrs are removed because the adhesive tape 5 serves as a sail.

When a predetermined time period for removing burrs has elapsed, the driving source is stopped, the barrel container 1 is lowered, and the lid is removed. Then, the support member group is taken out using tweezers or the like. At this time, since several supporting members 4 are held together by adhesive tape 5, they can be easily taken out. Furthermore, since the surface of the support member 4 is protected by the adhesive tape 5, it will not be scratched.

Although the case where adhesive tape is used for the jig has been described above, the present invention is not limited to this, and various other methods can be adopted, such as using threads to connect the supporting members, and these are also applicable to the present invention. Of course, it is included in the invention.

[0021]

According to the barrel polishing jig of the present invention, the support member is well stirred within the barrel, thereby shortening the barrel polishing time and facilitating separation from the contents of the barrel, thereby improving work efficiency.
