BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic multi-magazine device for a raw material and a molded lens, and an automatic device for injecting a raw material and a molded lens having the same. More particularly, The present invention relates to an automatic multi-magazine device for storing a lens, and an automatic device for injecting a raw material and a molded lens having the same.

Recently, digital cameras, camera phones, web cameras, and the like are becoming smaller and thinner, so that the size of the camera module embedded therein must be reduced. It is necessary to reduce the number and size of the lenses in order to reduce the size of the camera module. However, since the spherical aberration has a large spherical aberration and chromatic aberration, it is necessary to use a plurality of spherical lenses in order to eliminate such aberrations, which increases the size of the camera module. In order to compensate for these drawbacks, aspheric lenses, which are multifocal lenses, are used, and the demand for aspherical lenses is greatly increased in the case where the size of the camera module is gradually reduced.

Such an aspherical lens can be produced by a grinding method or a press molding method, and the grinding method is unsuitable for mass production. Recently, a press molding method in which a raw material is placed in an upper mold and a lower mold and an upper mold and a lower mold are assembled together and then mounted on a molding machine and molded through a high-temperature heating process, a pressing process, and a cooling process are used. After molding the lenses by such a press molding method, there is a need to take out molding lenses by ejecting and separating the molds, and aligning and storing the completed lenses in the holder. Then, new raw materials are supplied and aligned and put between the upper mold and the lower mold and transferred to the molding machine.

Conventionally, these series of steps have been manually performed, but the productivity has not been high. Unlike a mold having a single molding space, in a mold having a plurality of molding spaces, it is difficult to handle a small-sized raw material or a molded lens in detail, resulting in a problem that many molding defects occur.

To solve these conventional problems, an apparatus for manufacturing lenses by an automated molding method has been devised. Korean Patent Publication No. 2006-0001861 discloses an automated molding apparatus.

However, in the automated molding apparatus disclosed in the above publication, a plurality of cavities in a mold are simultaneously attracted and transferred to a lens array, or a plurality of cavities of a raw material sorting band are simultaneously attracted and transferred to a raw material sort , The number of mountable lens holders and original material holders is limited, so that holder replacement frequently occurs. During the replacement of the holder, there is a waiting time in which the robot can not work, resulting in a decrease in productivity.

On the other hand, in the stoker device of the automatic apparatus, the pusher device for pushing the raw material pallet is protruded from the outside of the equipment, which occupies a lot of installation space of the equipment and is not good for the safety of the worker. Since the pusher device and the pallet traverse device are driven by the pneumatic cylinder, the speed control by the air pressure change is not possible, and the raw material may protrude when driven. In addition, since the pneumatic cylinder, which can not perform precise position control, is used, the pallet may deviate from the correct position. In this case, there is a problem that a working error of the robot performing the work of transferring the raw material accommodated in the pallet occurs. On the other hand, since the stocker up / down device for moving the pallet up and down is also driven by a general linear motor and the start and stop are repeated by the serrated sensor detecting bar, there is a problem that the pallet deviates from the correct position due to sensor position deviation have.

In the present invention, a robot transfer and a holder gripping device for transferring a raw material holder and a lens holder are disposed inside the equipment, and two or more original material holder magazines and a lens holder magazine, which are independently driven, It has its purpose.

The present invention relates to an automatic multi-magazine apparatus for a raw material and a molded lens for storing a raw material to be inputted to a molding apparatus and storing a molding lens from a molding apparatus, the apparatus comprising: (i) a plurality of raw material holders, (Ii) a lens holder magazine for storing a plurality of lens holders accommodating the molding lens in the first axial direction, (iii) a lens holder magazine for holding the lens holder magazine and the raw material A magazine elevator for individually moving the holder magazines at regular intervals along the first axis direction; (iv) holder grippers for holding one of the work object lens holders and one of the work target work holders; And (v) robot transporters mounted with the holder grippers, respectively, for moving the holder grippers in a second axial direction orthogonal to the first axial direction, wherein the raw material holder magazines are arranged side by side Wherein the lens holder magazine comprises at least two lens holder magazines arranged in parallel to each other and wherein the holder gripper and the robot transfer are arranged in a direction perpendicular to the respective origin holder magazines, A plurality of lens holder magazines corresponding to each other, and a holder gripper of the robot transfer grips a working target holder from the holder magazine toward the molding apparatus, Device.

With such a construction, the raw material holder containing the raw material is always in the standby state, and the lens holder having the space for accommodating the lens is always in the standby state. Therefore, the waiting time of the second robot handler and the third robot handler working between the mold and the lens alignment stand or between the mold and the original material alignment stand can be reduced.

Wherein the original holder magazines are made up of a first original material holder magazine and a second original material holder magazine which are adjacent to each other in a row and the lens holder magazines are adjacent to each other to form another group 1 lens holder magazine and a second lens holder magazine. Alternatively, any one of the original material holder magazines and the lens holder magazine may be adjacent to each other in a juxtaposed relationship, and the other one of the original material holder magazines and the other one of the lens holder magazines may be arranged side by side It can be adjoined to form another group.

Wherein the first and second raw material holder magazines and the first and second lens holder magazines are independently driven by respective corresponding magazine elevators and the first and second raw material holder magazines and the first and second lens holder magazines are independently driven, Each of the holder grippers provided corresponding to the second lens holder magazine can be independently driven by each corresponding robot transfer. With this arrangement, when either one of the lens holders is filled or the original holder of one side is emptied, the magazine elevator and the holder gripper of the corresponding side are driven and the new lens holder and the original holder can be put on standby. Therefore, the waiting time of the second robot handler or the third robot handler can be reduced.

And holder aligners for positioning the lens holder and the raw material holder in a predetermined position, respectively. With this arrangement, errors can be reduced in the operation of the second robot handler and the third robot handler by accurately positioning the lens holder and the original material holder at the second and third robot handler working positions.

According to still another aspect of the present invention, there is provided a method of manufacturing a mold, comprising the steps of: (i) supplying a mold containing a raw material to a molding apparatus; (ii) molding the raw material in the molding apparatus; (Iii) disassembling the removed mold to take out the molded lens, disposing the molded lens on the lens alignment table, putting a new raw material into the disassembled mold, assembling the disassembled mold A second robot handler for sequentially aligning the molded lenses arranged on the lens alignment table to a lens holder, (v) a second robot handler for sequentially aligning the raw materials from a raw material holder containing new raw materials, And (vi) a raw material input and molded lens including the automatic multi-magazine apparatus according to any one of claims 1 to 5, Discloses an automation apparatus.

The raw material and the molded lens automatic multi-magazine device 100 for storing the raw material to be input to the molding apparatus 1 and storing the molding lens from the molding apparatus 1 are installed at the farthest side of the front side of the molding apparatus 1 .

FIG. 2 is a side view of the automatic multi-magazine device for a raw material and a molded lens according to an embodiment of the present invention, FIGS. 3A to 3C are a plan view, a front view and a side view of a raw material holder magazine, and FIG. FIG. 5 is a front view of one magazine elevator according to an embodiment of the present invention. FIG.

The automatic multi-magazine apparatus 100 according to the embodiment includes first and second lens holder magazines 48a and 48b forming a set, first and second original material holder magazines 49a and 49b constituting another set A multi-magazine elevator 40 for individually driving each lens holder magazine 48a, 48b and each of the raw material holder magazines 49a, 49b along a first axis direction (up-and-down direction of the apparatus) A holder gripping device 30 for pulling out the holders 68 and 69 from the holder magazines 48 and 49 and putting the holders 68 and 69 in the holder magazines 48 and 49 and the robot transfer 20, And holder aligners 60 for aligning the positions of the holders 68, 69 taken out from the magazines 48, 49 on the plane.

The lens holder 68 and the raw material holder 69 will be described with reference to the raw material holder magazine 49a with reference to Figs. 3A to 3C. As shown in Fig. 3A, the raw materials to be input to the molding apparatus are accommodated in rows and columns in each of the raw material holders 69a. As shown in FIG. 3B, the raw material holders 69a are stored in the raw material holder magazine 49a such that the raw material holders 69a are spaced apart from each other by a predetermined distance in the first direction.

4, the lens holder magazines 48 are arranged in parallel with each other in the second axial direction (left-right direction of the apparatus) to form a pair of first lens holder magazines 48a and second lens holders 48a, The first raw material holder magazine 49a and the second raw material holder magazine 49b are arranged in parallel to each other in the second axis direction so as to form a pair of the first raw material holder magazine 49a and the second raw material holder magazine 49b. .

Each of the lens holder magazines 48a and 48b and each of the raw material holder magazines 49a and 49b is attached to each corresponding multi-magazine elevator 40. [ That is, each of the four multi-magazine elevators 40 has a first lens holder magazine 48a, a second lens holder magazine 48b, a first original material holder magazine 49a, and a second original material holder magazine 49b For example, up to the thickness of the holders 68, 69, respectively. So that the work holders 68 and 69 loaded and stored in the holder magazines 48 and 49 can be moved to a position at which the second robot handler 5 or the third robot handler 6 can work have.

To this end, the multi-magazine elevator 40 is provided with a servo motor 42 integrated with the encoder 41. However, the scope of protection of the present invention is not limited thereto, and includes motor assemblies capable of position and speed control. For example, the multi-magazine elevator 40 may have an encoder-integrated stepper motor, or may be made of only a stepper motor capable of speed and position control by itself.

The angular position of the axis of the servo motor 42 can be known through the encoder 41 and further the position and the moving speed of the holder magazines 48 and 49 in the vertical direction can be known. The shaft of the servo motor 42 is connected to the ball screw 44 through the coupling 43 and the ball screw 44 is supported by the both end linear motion LM guide 46. The ball nut 44 is driven in unison with the ball screw 44 so that the ball nut 45 moves in the vertical direction when the ball screw 44 rotates in accordance with the rotation of the shaft of the servo motor 42. Since the ball nut 45 is assembled with the magazine support 47 fixed on the LM guide 46 and the magazine support 47 is connected to the holder support 66, when the shaft of the servo motor 42 rotates, The holder 47 and the holder support 66 are moved upward or downward.

By using the servomotor 61 capable of numerical control as described above and setting values programmed to move in the up and down direction by a predetermined pitch by the combination of the ball screw 44 and the ball nut 45, ) Can be precisely controlled. Thus, the height of the work holders 68, 69 can be accurately maintained at the working position of the holder gripper 31 of the holder gripping apparatus.

The robot transfer 20 is disposed in parallel with the first lens holder magazine 48a and the second lens holder magazine 48b so as to correspond to the first original material holder magazine 49a and the second original material holder magazine 49b And each of the robot transporters 20 is made up of the same. Each robot transfer 20 serves to transfer the work holder held in the holder magazines 48 and 49 to the molding apparatus 1 or to transfer it in the opposite direction. To this end, each robot transfer 20 is equipped with a holder gripping device 30. Each of the four robot transfers 20 and each holder gripping device 30 is controlled to independently transfer the four holder magazines 48a, 48b, 49a, 49b.

In this embodiment, a first lens alignment table 71a and a second lens alignment table 71b are disposed on the first lens holder magazine 48a and the second lens holder magazine 48b side, respectively, On the side of the magazine 49a and the second original material holder magazine 49b, a first original material alignment table 72a and a second original material alignment table 72b are disposed.

Meanwhile, although not shown in the drawings, the raw material injection and lens extraction molding apparatus according to an embodiment of the present invention may further include an alignment unit transfer device. The first and second lens alignment bars 71a and 71b can be reciprocated in the second axial direction independently of the first and second original material alignment bars 72a and 72b by the alignment and transfer device. In addition, the first lens array 71a and the second lens array 71b are independently reciprocated in the second axial direction, and the first source material alignment table 72a and the second source material alignment table 72b are reciprocated, Can also be reciprocated in the second axis direction. Thereby, there is an effect that the work moving range of the first robot handler 4 can be reduced.

Alternatively, only one lens alignment bar may be disposed on the lens holder 68 side, and only one raw material alignment bar may be disposed on the original material holder 69 side.

In another embodiment, although not shown in the figure, the first lens holder magazine 48a and the first original material holder magazine 49a are arranged in a juxtaposed manner in the second axial direction, The holder magazine 48b and the second original material holder magazine 49b may be arranged in another group in parallel with each other in the second axial direction. In this embodiment, the first lens alignment table 71a and the first original material alignment table 72a are disposed together between the first lens holder magazine 48a and the first original material holder magazine 49a forming a pair And the second lens alignment table 71b and the second original material alignment table 72b should be disposed between the second lens holder magazine 48b and the second original material holder magazine 49b constituting another set will be.

6 is a side cross-sectional view of a robot transfer 20 and holder gripping device 30 in accordance with an embodiment of the present invention. The holder gripper 31 of the holder gripping device 30 functions to clamp the holders 68 and 69, i.e., hold them. The holder gripper 31 is connected to one end of the connecting plate 33 fixed to the robot transfer 20 and is operated by the gripper actuator 32. The gripper actuator 32 may be a pneumatic cylinder, but the protective scope of the present invention is not limited thereto.

The robot transfer (20) has a servo motor (21) integrated with the encoder (22). However, the scope of protection of the present invention is not limited thereto, and includes motor assemblies capable of position and speed control. For example, the robot transfer 20 may be equipped with an encoder-integrated stepper motor, or may be made of only a stepper motor capable of speed and position control by itself.

The movement amount and the movement speed of the holder gripper 31 in the second axial direction can be known through the encoder 22. [ Here, the second axis direction is the direction perpendicular to the first axis direction, and means the same direction as the length direction of the robot transfer 20. The shaft of the servo motor 21 is connected to the ball screw 23 through the coupling 26 and the ball screw 23 is supported by the both end LM guide 25. When the ball screw 23 rotates in accordance with the rotation of the shaft of the servo motor 21, the ball nut 24 is driven integrally with the ball screw 23 so that the ball nut 24 moves in the front and rear direction. The ball nut 24 is assembled with a fixed block 27 fixed on the LM guide 25 and a connecting plate 33 is mounted on the fixed block 27. Therefore, when the servo motor 21 is driven, the holder gripping device 30 is moved in the second axial direction.

When the operation target holder is positioned at a predetermined height by the multi-magazine elevator 40, the holder gripping device 30 is moved to the position where the work target holder is located by the robot transfer 20, To hold the workpiece holder. Then, the robot transfer device 20 is driven to bring the holder gripping device 30 into the original position so that the workpiece holder comes to the working position of the second robot handler 5.

The robot transfer device 20 having such a configuration can precisely control the driving amount and the driving speed of the servo motor 21 by feeding back the output signal from the encoder 22. Therefore, it is possible to prevent skipping of a raw material or a molded lens which may occur when the work holder is transferred from the multi-magazine 47 to the working position of the second robot handler 5 along the second axis direction. By precisely controlling the drive amount, the work holders 68 and 69 can be accurately aligned to the working position of the second robot handler 5.

Since the holders 68 and 69 are transferred while holding the holders 68 and 69 with the holder gripper 31 at the time of transferring the workpiece holders 68 and 69, It is possible to prevent a misalignment of the holders 68 and 69 due to the unilateral deviation of the holders 68 and 69.

On the other hand, such a robot transfer 20 equipped with the holder gripping device 30 is disposed between the automatic multi-magazine device 100 and the molding device 1 as shown in Fig. That is, unlike the prior art, it is disposed so as not to protrude to the outside of the original material injection molding and molded lens extraction automation apparatus. Therefore, compared to the conventional method of taking out the protruded structure, the installation space of the facility can be reduced and the safety of the operator can be achieved.

When each robot transfer 20 brings the work holders 68 and 69 to the working position of the second robot handler 5 or the third robot handler 6 in the above-described embodiment, the second robot handler 5 places the molding lens in the lens alignment table 71 on the lens holder 68 while the third robot handler 6 takes out the original material from the raw material holder 69 and places the raw material on the raw material alignment table 72, . If the work holders 68 and 69 are not correctly aligned to the working positions of the second robot handler 5 or the third robot handler 6, the operation of the second robot handler 5 or the third robot handler 6 A time error occurs. Therefore, the holder aligner 60, which serves to align the two-dimensional positions on the plane perpendicular to the first axis of the work holders 68, 69, is used.

That is, the holder aligner 60 serves to align the two-dimensional position on the plane orthogonal to the first axis of the workpiece holder 68 while the multi-magazine elevator 40 serves to align the two- And aligns the position in the first axis direction.

7A shows a state in which the lens holder 68 and the raw material holder 69 are aligned in the working positions of the second robot handler 5 and the third robot handler 6 respectively and FIG. Lt; RTI ID = 0.0 > 60 < / RTI >

The drive actuator 61 of the holder aligner is attached to the magazine support 47. A bush fixing plate 65 is mounted on the magazine support 47 and guide bushes 64 are formed on four positions of the bush fixing plate 65. The end of the rod of the actuator 61 is connected to the holder support 66 by a universal joint 62. Four guide pins 63 are provided in the lower portion of the holder support 66 in correspondence with the guide bushes 64. The guide supports 63 are provided on the upper portion of the holder support 66, The guide bush 64 guides the movement of the holder support 66 in the up and down directions as the guide post 63 moves within the guide bush 64. [ At this time, the universal joint 62 serves to prevent a directional deviation from occurring when the unidirectional motion of the rod of the actuator 61 is transmitted to the holder support 66.

Four grooves 75 are formed in the holders 68a, 68b, 69a, and 69b, and four grooves 75 and four alignment pins 67 are positioned to correspond to each other. When the holder gripper 31 transfers the holders 68 and 69 from the magazine by the driving of the robot transfer 20 described above, the holder support 66 is finally elevated upward by the actuator 61 Alignment pins 67 are fitted into the four grooves 75. As shown in Fig. In such a process, the lens holders 68a and 68b are aligned to the working position of the second robot handler 5, and the raw material holders 69a and 69b are aligned to the working position of the third robot handler 6.

The actuator 61 of the holder aligner is driven by a pneumatic cylinder. However, the scope of protection of the present invention is not limited thereto, and various actuators can be used.

The holder aligner 60 is provided on the first lens holder 68a, the second lens holder 68b, the first raw material holder 69a and the second original material holder 69b in the same manner as the robot transfer 20 And are independently controlled to drive the four holders independently.

Hereinafter, the operation process of the above-described raw material and molded lens automatic multi-magazine apparatus 100 will be described.

First, the process of storing the molded lens taken out of the molding apparatus 1 and taken out of the mold and placed on the lens alignment table 71 in the automatic multi-magazine apparatus 100 will be described. The first and second lens holder side multi-magazine elevators 40 are driven in the vertical direction so that the first lens holder 68a and the second lens holder 69a are positioned at the same height as the holder gripper 31. Then, each robot transfer 20 is driven to simultaneously move each holder gripping device 30 to the first lens holder magazine 48a and the second lens holder magazine 48b, After holding the lens holder 68, the robot transfer 20 is driven to pull the hollow lens holder 68 out of the first lens holder magazine 48a and the second lens holder magazine 48b, (5). Then, the actuator 61 of each holder aligner 60 is driven so that the first lens holder 68a and the second lens holder 68b are properly positioned. Thereafter, the second robot handler 5 is driven to suck the lenses in the lens alignment table 71 one by one and sequentially align them to one of the lens holders (for example, the first lens holder 68a).

When all of the molding lenses are loaded on the first lens holder 68a, the second robot handler 5 sequentially aligns the molded lenses on the second lens holder 68b. Meanwhile, the robot transfer 20 on the first lens holder 68a side is pushed while holding the first lens holder 68a with the holder gripper 31 and stored in the first lens holder magazine 48a. Then, the first lens holder side multi-magazine elevator 40 rotates the first lens holder magazine 48a in a predetermined direction so that the empty first lens holder 68a to be loaded with the molding lenses is at the same height as the holder gripper 31 (The distance between two vertically adjacent holders). The holder gripping device 30 on the side of the first lens holder 68a pulls the empty first lens holder 68a out of the first lens holder magazine 48a and moves it to the working position of the second robot handler 5. Therefore, the lens holders 68a and 68b are always in the waiting state, so that the waiting time of the second robot handler 5 can be reduced. On the other hand, conventionally, when the lens holder 68 is filled with the lens, the second robot handler 5 can not work until it is loaded on the lens holder magazine 48_ and a new lens holder is taken out.

Thereafter, the first and second lens holder magazines 48a and 48b, in which both the first and second lens holders 68a and 68b filled with the molding lens are loaded, are moved by the operator to the inspection process, The first and second lens holder magazines 48a and 48b, in which the lens holders 68 are mounted on the respective chambers, are mounted.

Conversely, the first and second raw material holders 69a and 69b containing the raw materials to be input to the molding apparatus 1 are transferred from the first and second raw material holder magazines 49a and 49b to the raw material sorting bases 72a , And 72b will be described.

The first and second raw material holder side multi-magazine elevators 40 are raised or lowered so that the first and second raw material holders 69a and 69b containing the raw materials are at the same height as the height of the holder gripper 31 . The robot transfer device 20 for the first and second raw material holders is driven to move the holder gripping devices 30 to the first and second raw material holder magazines 49 and 49b, The first and second raw material holders 69a and 69b are respectively gripped with the first and second raw material holders 69a and 69b and then the respective robot transfer 20 is driven to pull the first and second raw material holders 69a and 69b, From the binary material holder magazines (49a, 49b) and moved to the working position of the third robot handler (6). Then, the actuators of the first and second raw material holder side holder aligners 60 are driven to position the first and second raw material holders 69a and 69b in position.

Thereafter, the third robot handler 6 is driven to suck the raw materials one by one from one of the raw material holders, for example, the first raw material holder 69a, and sequentially align them to the raw material sorting stands 72a and 72b do. Thereafter, when the original material is no longer left in the first raw material holder 69a, the third robot handler 6 sucks the raw materials one by one in the second raw material holder 69b, (72b). Meanwhile, the holder gripper on the first original material holder 69a side and the robot transfer are moved to the first original material holder magazine 49a while loading the empty original material holder 49a. The first raw material holder side multi-magazine elevator 40 raises or lowers the first raw material holder magazine 49 by a predetermined distance so that the new first raw material holder reaches the same height as the corresponding holder gripper 31 . Then, the holder gripping device on the side of the first raw material holder 69a pulls out the first raw material holder magazine 49a filled with the raw material from the first raw material holder magazine 49a, Position. Therefore, the raw material holders 69a and 69b are always in the waiting state, so that the waiting time for the work of the third robot handler 6 can be reduced. On the other hand, conventionally, when the raw material holder 69 becomes empty, the third robot handler 6 can not work until it is loaded on the raw material holder magazine 49 and a new raw material holder is taken out.

Thereafter, when the original material holder magazine 49 is filled with the empty holders, the operator repeats the above operation by detaching the magazine and replacing the magazine loaded with the new original material holders.

According to the above-described operation, the raw material and molded lens automatic multi-magazine apparatus 100 according to the embodiment of the present invention can reduce the work waiting time of the second robot handler 5 and the third robot handler 6, Because the operation is performed automatically, the production efficiency can be increased.

Hereinafter, the operation of the apparatus for injecting raw material and injecting molded lens according to one embodiment of the present invention having such a configuration will be described. First, a process of storing the lens formed in the molding apparatus 1 in the lens holder 68 of the automatic multi-magazine apparatus 100 will be described.

When the mold having the molded lens is conveyed along the take-out conveyor 2, it is conveyed to the first position by the pusher. Then, the mold is transferred to the rotation regulation portion 7 by the multi-hand mounted on the first robot handler 4. [ After the guiding ring (not shown) surrounding the mold is withdrawn from the rotation regulating part 7, the mold is rotated to correct the position of the mold. Then, the multi-hand of the first robot handler 4, (8). The upper mold is disassembled by the multi-hand of the first robot handler 4 while the mold is fixed in the rotation regulation part 8, the molding lens is sucked and taken out, and is seated on the lens alignment table 71. Then, the second robot handler 5 sequentially aligns and stores the molding lens, which is seated on the lens alignment table 71, in the first and second lens holders 68a and 68b. When one of the lens holders (e.g., 68a) is filled during the storage operation, the second robot handler 5 aligns with and stores with the other lens holder 68b. The filled lens holder 68a is transported by the automatic multi-magazine device 100 to the lens holder magazine 48a and the empty lens holder 68a is moved from the lens holder magazine 48a to the second robot handler 5 The work waiting time of the second robot handler 5 can be eliminated. This operation is repeated until the first and second lens holders 68a and 68b filled with the molded lens are all loaded in the first and second lens holder magazines 48a and 48b.

Next, a process of supplying the raw material to be fed in the forming apparatus 1 from the raw material holder of the automatic multi-magazine apparatus 100 to the forming apparatus 1 will be described.

When the automatic multi-magazine device 100 places the first and second raw material holders 69a and 69b filled with the raw material aligned in the working position of the second robot handler 5, the second robot handler 5, 72b of the raw materials on the first and second raw material holders 69a, 69b. After the first robot handler 4 puts the raw material placed on the raw material alignment tables 72a and 72b into the mold, the upper mold is placed on the raw material and assembled, the guide ring is combined with the mold, (3). Here, before the raw material is put into the mold, the raw material center aligning device 10 may be roughed according to the shape of the raw material. Then, the mold is put into the molding apparatus 1 through the supply conveyor 3, and the molding is completed through a heating process, a pressing process, and a cooling process. On the other hand, when all the raw materials on one raw material holder (for example, 69a) are transferred to the raw material sorting table 72a by the second robot handler 5, the second robot handler 5 moves The raw materials on the raw material holder 69b are transferred to the raw material sorting table 72b. Accordingly, it is possible to reduce the work waiting time of the third robot handler 6 and to improve the production efficiency.

The raw material and molded lens automatic multi-magazine apparatus of the present invention can reduce the waiting time of the second robot handler and the third robot handler working between the mold and the lens aligning stand or between the mold and the raw material aligning stand. Further, since the automatic multi-magazine device does not protrude out of the original material injection molding and extrusion molding device, the installation space of the device can be reduced and the safety of the operator can be improved. Since the feed amount and the feed speed of the holder can be precisely controlled by using the servo motor, it is possible to prevent skipping of the raw material or the molded lens at the time of transferring the holder. In addition, since the holder is transported while being held by the holder, it is possible to prevent the holder from tilting on one side and prevent misalignment of the holder in the correct position. In addition, since the holder is transferred to the working positions of the second and third robot handlers and the holder is aligned by the holder aligner to the correct position, the occurrence of errors in the operation of the second and third robot handlers can be reduced.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
