Description

Vacuum jig for grinding, which allows the surface grinding and polishing process of the lens to be moved under vacuum.

The present invention relates to a vacuum jig, in more detail to form one or more concave holes for seating the lens, one side of the vacuum coupled to and separated from the vacuum pump, the nozzle tube with a locking valve is integrally formed The present invention relates to a vacuum vacuum jig that is capable of moving a surface grinding and polishing process of a lens, which can be moved by moving to the next work process step while the lens is fixed by separating the jig from the vacuum pump in a vacuum state.

In general, lenses used for optical and lighting should have a precise surface grinding and polishing process, but the conventional lens grinding and polishing process is the first manual grinding (edge) of the projection (processing portion) formed on the outer peripheral surface After arranging by the work, after the secondary surface finishing process by diamond, the polishing operation provided by step is performed.

However, the lens processing process is a problem that the workability is significantly lower due to the decrease in production efficiency due to the process loss by the number of lenses, and the process of checking the processing dimensions one by one depends on the technical capability of the individual worker. Due to the large tolerances in product dimensions, mass production of defective products is feared. Accordingly, in order to solve the above problems, in order to process a large amount of lenses in a short time with high quality, a rotary polishing jig, which is a surface polishing apparatus using diamond, is provided to perform surface smoothing and polishing operations. The rotary polishing jig is formed on a plurality of semi-circular concave grooves and the inner circumferential end of the concave groove so as to fit the aspherical lens on the square surface so that the plurality of lenses can be firmly attached to the inner circumference of the concave groove Therefore, in order to use the rotary polishing jig, an adhesive is applied to fix the lens by inserting it into the recess, but when the grinding and grinding work is completed, the adhesive is applied. To separate the old lens, it is heated and melted by a heater, and then the lens is separated. To remove foreign substances such as adhesives, cleaning is performed using chemicals, which makes the work process complicated and reduces production efficiency. There is a problem in that it provides a harmful working environment because of the use of. A vacuum vacuum jig is used to fix it without using an adhesive to fix the ball. The polishing vacuum jig has a rectangular shape, and a plurality of recessed holes are formed on the upper surface thereof, and one side is connected to the hose of the vacuum pump. When the lens is attached to the recessed hole in the fixed state, the vacuum air is sucked into the vacuum jig to draw the internal air of the vacuum jig into a vacuum state. The lens is ground and fixed in the recessed hole by the suction force. After finishing the work, the vacuum is released to remove the fixed lens and only the lens is transported to the next processing step.

However, since the polishing vacuum jig sucks and draws the air in the inside while fixed to the vacuum pump, the lens processing operation can be facilitated, but the conventional polishing vacuum jig is in a fixed state that cannot be separated from the vacuum pump. Therefore, there is a problem that the polishing vacuum jig itself is impossible to move.

In addition, the process of processing the lens is not a single process but consists of various work processes including a polishing and grinding process. Therefore, each time a process is finished, the lens is released in a state where the internal vacuum state of the polishing vacuum jig is released. Since it is separated and transported to the next process, the lens is mounted on the vacuum jig attached to the vacuum pump, and the next processing is performed. Therefore, it is inconvenient to install a vacuum pump and a polishing jig for each processing process, and the installation cost is high. There is a problem.

In addition, in the process of processing the lens, the lens is transported to the polishing vacuum jig installed in each of the following processes in a state in which it is separated from the polishing vacuum jig at the end of each process. Since it is separated and moved, it should be correctly mounted on the vacuum vacuum jig, but since the operator has to work by hand, only the lens is changed so that precision machining cannot be performed, which causes a high defect rate.

Therefore, the present invention polishing vacuum jig as a means for solving the above problems is formed in the concave hole to attach one or more lenses, one side can be separated and combined with the vacuum pump, the concave hole in the vacuum state Provided is a polishing vacuum jig in which a nozzle tube with a locking valve is integrally formed so as to carry a lens fixed to it.

As described above, in the present invention, the lens is mounted on the polishing vacuum jig even if the polishing vacuum jig is removed from the vacuum pump to transport the lens attached to the polishing vacuum jig to the suction power of the vacuum pump to the next processing step. Since they are transported together in a fixed state, they are maintained until the end of the processing process, so that the lens can be precisely processed.

In addition, the lens can be fixed to the vacuum vacuum jig in a vacuumed state to be transported together in the next processing process, there is no need to install a polishing vacuum jig and a vacuum pump for each process has the effect of reducing the installation cost.

The present invention polishing vacuum jig is characterized in that the lens is separated and combined with the vacuum pump in a fixed state in a vacuum state.

Therefore, the present invention is a block-shaped concave hole is formed in the upper surface so that one or more lenses can be mounted, the recess hole in the hemispherical silicon so as to maintain and fix the bottom and vacuum state of the lens by the suction force of the vacuum pump The packing is inserted, one side is provided with a nozzle tube to be separated and coupled with the vacuum pump, the nozzle tube is provided with a lock valve for interfering air intake and discharge.
