The present invention relates to a high-pixel multifocal lens manufacturing apparatus, and in particular, when manufacturing a high-pixel multifocal lens, the transfer arm is in close contact with the side of the mold body in the forming chamber, and when the transfer arm is moved to the next process position, By contacting, the heat dissipation hole formed in the side of the mold body is not blocked, and the formability of the lens is improved, and the initial position setting of the transfer arm according to the size of the mold body can be adjusted very finely and precisely, and the front side of the molding chamber The present invention relates to a high-pixel multifocal lens manufacturing apparatus capable of improving the workability of an operator by preventing high heat inside the molding chamber from being released to the outside by installing a blocking plate in the same.

The high-pixel (megapixel) multifocal glass lens has an aspherical surface to increase transmittance and refractive index, and is a key component that enables high quality and miniaturization of optical modules.

These high-pixel multifocal lenses are widely applied to high-pixel mobile phones, cameras, CD and DVD players, laser printers, and projectors, and are essential parts that influence the performance of the products.

High-pixel multifocal lenses can be divided into plastic products and glass (glass) products, which are increasingly used because plastic products have lower resolution than glass products.

 The manufacturing of the high-pixel multifocal glass lens is made by a separate molding apparatus, and the applicant has previously filed a high-pixel multifocal lens manufacturing apparatus as a patent application 2005-108404.

However, since the prior art does not have a means for fine-adjusting the initial position of the transfer arm for transferring the mold body to the next process position in the molding chamber according to the size of the mold body, the initial position of the transfer arm is precisely determined. There was a problem that could not be set, and since only the glass for seeing is formed on the front side of the molding chamber, the high temperature inside the molding chamber is discharged to the front side of the molding chamber as it is. It was happening.

In addition, because the transfer arm is in surface contact with the side of the mold body, the transfer arm blocks the heat dissipation hole formed in the side of the mold body when the transfer arm is in close contact with the side of the mold body to move the mold body to the next process position. This phenomenon occurs, which causes a problem in that the heat generated inside the mold body is not released to the outside, thereby deteriorating the lens formability.

Therefore, the present invention for solving the above problems is to form a zero adjustment unit to finely adjust the initial position of the transfer arm for transferring the mold body to the next process position in the working body constituting the transfer means, according to the mold body size, A high-pixel multifocal lens is formed on the transfer arm which closely adheres to the mold body and transfers the mold body to the next process position. In the manufacturing chamber, when the transfer arm is in close contact with the side of the mold body and is transferred to the next process position, the close contact between the transfer arm and the mold body does not block the heat dissipation hole formed in the side of the mold body, thereby forming the lens. Performance is improved, and the initial position of the transfer arm can be adjusted very finely and precisely according to the size of the mold body. As the installation of the blocking plate on the front is not the high heat inside the forming chamber is not discharged to the outside is a high-pixel to improve the operability of the operator and for the purpose of providing the focus lens manufacturing apparatus.

A loading plate 12 serving as a loading place of the mold body 100 is formed on the right side of the molding chamber 8, and one side of the loading plate 12 is a loading bar 14 mounted on the loading cylinder 13. ) Is configured to push the mold body 100 located on the loading plate 12 into the molding chamber 8 while moving forward and backward.

Then, an input conveyor 11 for transferring the mold body 100 to the loading plate 12 is formed on the front surface (lower direction on the drawing) of the loading plate 12.

The mold body 100 is supplied to the input conveyor 11 by an automatic device such as an operator or a robot.

On the other hand, a discharge plate 81 is formed on the left side of the molding chamber 8, on which the mold body 100 passing through the molding chamber 8 is seated, and on the rear surface (upper side in the drawing) of the discharge plate 81. A discharge bar 83 for pushing the mold body 100 to the discharge conveyor 84 is formed to be mounted on the discharge cylinder 82.

That is, the mold body 100 transferred by the feeding conveyor 11 is pushed by the loading bar 14 to be supplied into the molding chamber 8, and the preheating member 30 provided in the molding chamber 8 is pressed. The mold body 100 discharged after being formed by the member 40 and the cooling member 50 is pushed by the discharge bar 83 and discharged to the outside through the discharge conveyor 84.

The movement of the mold body 100 in the molding chamber 8 is made by the position transfer means 60, the position transfer means 60 includes a front and rear cylinder 64 and the left and right cylinder 65. .

As shown in FIG. 3, the loading means 10 and the discharge means 80 are installed to face the front of the cabinet 1 so that an operator or an automated robot can conveniently carry out the injection and discharge of the mold 100. Will have the effect.

4 is a view illustrating a state in which the preheating member 30, the pressing member 40, and the cooling member 50 of the pressing molding means 20 applied to the present invention are installed.

The first to third preheating parts 31 to 33, the pressurizing member 40, and the first to third cooling parts 51 to 53 are installed in a line inside the molding chamber 8, and are respectively preheated. The mold body 100 is located at each pressing position and cooling position.

That is, in the present invention, the mold body 100 in which the base material is embedded is continuously supplied into the molding chamber 8, and in this state, the first to third preheating parts 31 to 33 and the pressing member 40 are provided. The first to third cooling units 51 to 53 simultaneously operate to preheat, pressurize, and cool the mold body 100. When one working process is completed, the position transfer means 60 described above is a mold body ( By transferring 100) to the next process position, a continuous multifocal lens manufacturing process is achieved.

Meanwhile, in the first and second cooling units 51 and 52, a lower cooler 9a is stacked above the base plate 9 formed at the bottom of the molding chamber 8, and the lower cooler 9a is disposed. On the upper side of the heat conduction plate (9b) is laminated so that the cooling by uniformly supplying the cold air of the lower cooler (9a) to the mold body 100,

The third cooling unit 53 is configured such that the lower body cooler 9a is stacked on the separate support part 531a so that the mold body 100 can be directly placed on the upper surface of the lower cooler 9a. On the bottom of the portion 531a, a height adjusting plate 531b for adjusting the height of the lower cooler 9a is formed to be detachable.

That is, when the heat conduction plate 9b wears 0.3 to 0.5 mm when used for a long time, the heat conduction plate 9b is worn and thus, when the stepped with the lower cooler 9a of the third cooling unit 53 occurs. After removing the height adjustment plate (531b) from the supporting portion (531a) and grinding the grinding step by step, the overall height is equal to the bottom of the supporting portion (531a), the sliding movement of the mold 100 is smoothly performed. .

As described above, since the height adjusting plate 531b is detachably formed under the supporting part 531a, the lower cooler of the third cooling part 53 even if a step occurs between the third cooling part 53 and the other cooling part. Without replacing the whole module, the height adjustment plate (531b) will be able to reuse after grinding.

On the other hand, Figure 5 and Figure 6 shows the position transfer means 60 applied to the present invention.

The position transfer means 60 functions to transfer the mold body 100 introduced into the molding chamber 8 to the next process position.

The mold body 100 is continuously supplied to each process as shown in the drawing, and thus the front surface is moved from the horizontal arm 61 to transfer a plurality of mold bodies 100 existing at each process position to the next process position at once. A plurality of transfer arms 62 corresponding to the number of processes are formed to face the grooves, and grooves 66 are formed on one side of the transfer arms 62 so as to form edge portions that are in line contact with the side portions of the mold body 100. do.

At this time, the contact portion 622 is formed on one end of the transfer arm 62 so that the groove 66 can be formed, the contact portion 622 is an isosceles triangle and its cross section as shown in FIG. As shown in FIG. 8, even if the transfer arm 62 is in contact with the side portion of the mold body 100, the contact portion 622 and the gold are formed to gradually narrow toward one side to transfer the mold body 100 to the next process position. The mold 100 is in line contact so as not to block the heat dissipation hole 100a formed at the side portion of the mold body 100.

That is, if the transfer arm 62 is in contact with the mold body 100 when the transfer arm 62 is in close contact with the side portion of the mold body 100, the heat dissipation hole 100a of the mold body 100 is in close contact. This blockage prevents heat inside the mold body 100 from being discharged to the outside, which deteriorates the moldability of the lens, thereby degrading the quality of the lens. However, as in the present invention, the transfer arm 62 and the mold body ( When the line 100 is in line contact, the heat dissipation hole 100a is not blocked, thereby improving the moldability of the lens, thereby producing a high quality lens.

In addition, an actuator 63 in a state of being connected to the horizontal arm 61 is formed at an outer side of the rear surface of the forming chamber 8, and the front and rear cylinders for advancing the horizontal arm 61 forward and backward ( 64 is connected, and as shown in FIG. 5, left and right cylinders 65 for driving the actuator 63 in left and right directions are formed at one side of the rear surface of the molding chamber 8 as shown in FIG. 3.

In addition, as illustrated in FIG. 6, a zero adjustment unit 69 is formed on the actuator 63 to precisely set the initial position of the transfer arm 62, and one side of the zero adjustment unit 69 is molded. It is connected to the rear surface of the chamber (8), the other side is connected to the actuator (63), the end of the zero adjustment unit 69 is formed with an adjustment nut (69a) that the user can rotate the operation.

That is, as the user rotates the adjusting nut 69a, the zero adjustment unit 69 moves in the left and right directions to finely move the entirety of the actuator 63 to the left or the right, and thus the initial position of the transfer arm 62. Will be able to precisely adjust.

The initial position of the transfer arm 62 is finely adjusted according to the size of the mold body 100.

And, a ruler 67 is formed at the upper end of the rear surface of the molding chamber 8, and a scale indicating portion 68 which instructs the scale of the ruler 67 is formed at the upper end of one side of the actuator 63. There is a door.

Accordingly, the user can set the initial position of the transfer arm 62 precisely by rotating the adjusting nut 69a while watching the scale of the ruler 67 indicated by the scale indicating portion 68.

The position transfer means 60 configured as described above is preheated, pressurized, and pressed by the press forming means 20 provided in the forming chamber 8 when a predetermined control signal is applied from the controller 96 of the control means 90. At the time when the cooling operation is completed, the transfer arm 62 is advanced (1 direction) by the front and rear cylinder 64 to be located at one side of the mold body 100 at each process position as shown in the drawing, and then the left and right cylinders While moving to the left (② direction) on the drawing by 65, each mold body 100 is transferred to the next process position. In this state, the transfer arm 62 retreats a little back and then retreats in direction ③ and again ④ Retreat in the direction and return to the original position.

By the operation of the position transfer means 60 as described above, the preheating, pressurizing, and cooling operations performed in the molding chamber 8 can be continuously performed.

On the other hand, the radiation shielding plate (8a) for blocking the heat generated in the molding chamber 8 to the front portion is coupled to the front portion of the molding chamber (8).

By forming the radiant heat shield plate (8a), the heat inside the forming chamber (8) is not radiated to the front, so that the operator can perform the work in a more comfortable and stable state.

As described above, the present invention forms a zero-adjustment portion for fine-adjusting the initial position of the transfer arm for transferring the mold body to the next process position in the working body constituting the conveying means according to the mold body size, and closely adheres to the mold body. Forming a close contact with the mold body in line with the transfer arm for transferring the mold body to the next process position, and forming a blocking plate to block external emission of radiant heat on the front surface of the molding chamber, thereby forming a high-pixel multifocal lens. In the chamber, when the transfer arm is in close contact with the side of the mold body and transferred to the next process position, the contact between the close contact of the transfer arm and the mold body does not block the heat dissipation hole formed in the side of the mold body, thereby improving the formability of the lens. The initial position setting of the transfer arm according to the size of the mold body can be adjusted very finely and precisely, as well as on the front side of the molding chamber. By installing the blocking plate, high heat inside the molding chamber is not discharged to the outside, and thus the effect of providing a high-pixel multifocal lens manufacturing apparatus that can improve the workability of the operator can be expected.
