Description

  The present invention relates to a method and a system for manufacturing a lens, and more particularly, to an improvement in a method and a system for manufacturing a spectacle lens suitable for low-volume, multi-product production.

  In the production of spectacle lenses, different prescriptions are often applied for each customer, and small-lot, multi-product production is required. Especially in the case of plastic lenses for spectacles that are applied to various products in recent years, the lens molding process Therefore, when manufacturing a product through a dip coating process, a dyeing process, a vapor deposition process, etc., various processes according to the prescription are performed in each manufacturing process.

  In order to select a manufacturing process accurately in response to small-quantity, high-mix production, the work instructions according to the prescription are described in two-dimensional barcodes in each manufacturing process. One that reads a barcode and selects a necessary process is known (for example, Patent Document 1).

In the vapor deposition process for coating the antireflection film or the like, the vapor deposition process is performed by setting a lens on the dome of the vacuum vapor deposition apparatus.
Japanese Patent Laid-Open No. 8-294777

  However, in the above conventional example, various work instructions in each manufacturing process can be transmitted by a two-dimensional bar code. However, when the production is temporarily stopped and restarted due to a trouble of the manufacturing apparatus, the necessary processing is performed. There is a problem in that it is easy to cause troubles such as missing the mark or performing the same processing twice, resulting in a defective product and a decrease in productivity. In other words, it is impossible to know the processing history of what processing or processing has been performed during each manufacturing process.

  In particular, in the above vapor deposition process, a large number of coats are formed on the lens, but it is difficult to visually confirm whether or not the lens has been processed correctly, and even if the same vapor deposition film is formed, the convex and concave surfaces are not formed. Since the processing conditions are different, in addition to the above-described missing or overlapping processing, errors in setting the processing conditions are likely to occur.

  Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to monitor processing history in a lens manufacturing process to prevent missing processing, duplication, or processing condition setting errors.

The present invention includes a first control device that manages manufacturing information relating to the manufacturing of a lens, and a second control device that controls a manufacturing device that sequentially processes the convex and concave surfaces of the lens. A lens manufacturing method for processing a convex surface and a concave surface of a lens based on the lens-specific identifier that is set in advance and attached to the lens is read by the first control device, and the manufacturing device A procedure for setting a lens, a procedure for setting a first machining command necessary for machining the convex surface of the lens based on the manufacturing information corresponding to the identifier, and the first machining to the second control device A procedure for transmitting a command to process the convex surface of the lens, and a procedure for the second control device to transmit a result of the convex surface processing to the first control device when the processing of the convex surface of the lens is completed. , The first system The apparatus stores a result of processing the convex surface in association with the identifier as a processing history, a procedure for inverting and setting the convex surface and the concave surface of the lens, and the procedure corresponding to the inverted lens identifier. Based on the manufacturing information, a procedure for setting the second processing command necessary for processing the concave surface of the lens, and the second processing command is transmitted to the second control device to process the concave surface of the lens. And the second control device transmits the result of the concave surface processing to the first control device when the concave surface processing of the lens is completed, and the first control device processes the concave surface. The procedure of setting the first machining command and the procedure of setting the second machining command are described with reference to the machining history. 1 and 2 machining commands Constant, and the processing is a deposition process for forming a deposited film on the convex surface and the concave surface of the lens.

  Therefore, the present invention stores the processing history in the first control device (for example, the management server 5 and the management terminal computer 6) every time the processing of the convex surface and the concave surface of the lens is completed. By setting the processing command while referring to the processing history, it is possible to prevent missing processing, duplication of the same processing, or processing command setting mistakes, greatly improving the productivity in lens manufacturing. be able to.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows an example in which the present invention is applied to a vapor deposition process for forming a film such as an antireflection film or a water repellent coating on a plastic lens for spectacles. In this vapor deposition step, a molded spectacle lens (hereinafter simply referred to as a lens) is deposited in a vacuum vapor deposition apparatus to form an antireflection film, a water repellent film, and the like.

  The lenses 12 are placed on the tray 10 as a pair of left and right and arrive at the vapor deposition step. The tray 10 is provided with a work instruction sheet 11 for instructing processing information of the lens 12. The work instruction sheet 11 includes a tray ID obtained by encoding the lens information of the lens 12 and an identifier indicating the processing information. It is described as code 111. The lens information indicates the material, refractive index, shape, and the like of the lens 12, and the processing information indicates the type and number of vapor deposition films formed on the lens 12. The lens information, processing information, and history information that will be described later are used. Manufacturing information of the pair of lenses 12 is configured.

  In the management server 5 to be described later, lens information (lens refractive index, material, etc.) and processing information (deposition film type) according to the specifications of the lens 12 are set in advance corresponding to the tray ID. By reading the barcode 111 of the instruction sheet 11 and inquiring to the management server 5 from the management terminal computer 6 to be described later, it is possible to grasp a processing command necessary for the lens 12. The processing information is composed of various kinds of information related to the manufacture of the lens, and the processing command means information necessary for the vapor deposition process.

  The tray 10 arriving at the vapor deposition process is moved to the cleaning rack 8 together with other lenses 12 that form the same vapor deposition film.

  The lens 12 accommodated in the cleaning rack 8 constitutes a lot in which the barcode 111 is read from the work instruction sheet 11 of each tray 10 and is subjected to the same processing, and the type of vapor deposition film and the processing parameters are the same. Consists of.

  After the lens 12 is cleaned by the cleaning device 3, the lens 12 is transferred to the dome 1 </ b> A of the vapor deposition device 1, and a vapor deposition film is formed by the vapor deposition device 1.

  In the vapor deposition process, a management terminal computer 6 that constitutes the lot and commands a processing command based on processing information to the controller 4 that controls the vapor deposition material 1 and relays information between the management server 5 and the controller 4. Is installed.

  The management terminal computer 6 is connected to the management server 5 serving as the center of the manufacturing management system via the network 50, and transmits / receives lens information, processing information, and processing history. On the other hand, the management terminal computer 6 and the controller 4 are connected via a serial port such as RS232C. The management terminal computer 6 mainly transmits a processing command to the controller 4, and the controller 4 mainly transmits the processing result to the management terminal computer 6. Send to. The network 50 is configured by a LAN or the like.

  The entrance terminal computer 6 includes a barcode reader 61 that reads the barcode 111 of the work instruction sheet 11, and an input device and a display device such as a display, a keyboard, and a mouse.

  The management server 5 operates a database 51 that stores lens information, processing information, and processing history of the lens 12 for each tray ID, and manages information related to the entire product manufacturing (each manufacturing process). On the other hand, the management terminal computer 6 performs manufacturing information management regarding the vapor deposition process. In this example, a manufacturing management system is constructed from the management server 5, the management terminal computer 6, and the controller 4 of the vapor deposition apparatus 1. The management server 5 is also connected to a management terminal computer for other processes (not shown) (for example, a molding process, a dyeing process, and a vapor deposition process).

  The dedicated line for forming the vapor deposition film on the lens 12 includes the cleaning device 3 and the vapor deposition device 1, and the vapor deposition device 1 metalizes the antireflection film and the water repellent film on the lens placed on the internal dome 1 </ b> A. It is formed by the vapor deposition material.

  Next, the overall processing flow in the vapor deposition process will be described with reference to FIGS. 2 shows the flow of data between the devices, and FIG. 3 shows the processing flow of the lens 12.

  A set of lenses 12 and a work instruction sheet 11 for the lenses 12 are placed on the tray 10 that has arrived at the vapor deposition step. First, in the vapor deposition process, in order to process a plurality of lenses 12 forming the same vapor deposition film as one lot, a lot set process (S1 in FIG. 3) is performed.

  This lot set is read by the bar code loader 61 of the management terminal computer 6 to read the bar code 111 of the work instruction sheet 11 of the tray 10 and extract the tray ID from the bar code 111 (S101 in FIG. 2).

  Next, the tray ID is transmitted to the management server 5, and the lens information and the processing information of the lens 12 corresponding to the tray ID are acquired (S102 in FIG. 2).

  When there are a plurality of trays 10, the operations of S101 and S102 are repeated. At this time, the lens 12 is moved to the cleaning rack 8 with the tray 10 having the same processing condition (processing information) as one lot, and if there is a tray ID with a different processing condition, a warning is issued and excluded from the lot.

  When the input of the tray ID of the lens 12 to be loaded into the cleaning rack 8 is completed, the lens 12 of each tray 10 is accommodated in the cleaning rack 8 and the lot set is completed, the cleaning rack 8 is loaded into the cleaning device 3 to enter the lens 12. (S2, S3, S103).

  When the cleaning of the lens 12 is completed, the lens 12 of the cleaning rack 8 is transferred to the dome 1A of the vapor deposition apparatus 1 (S4, S104).

  In the vapor deposition step, first, after forming a vapor deposition film on the convex surface of the lens 12, cleaning is performed again, and then a concave vapor deposition film is formed.

  Here, when the lens 12 for processing the convex surface is transferred to the dome 1A, the management terminal computer 6 performs a convex surface process moving process (S5 in FIG. 3) to check the processing history of each lens 12 (S5 in FIG. 3). S105). When the convex surface process moving process is completed, the management terminal computer 6 issues a lot number to the management server 5. The management server 5 receives this lot number and detects that the convex surface processing has started.

  Based on the processing information acquired from the management server 5, the management terminal computer 6 sends processing commands (processing conditions such as the type of vapor deposition film and temperature) necessary for the current convex surface processing to the controller 4 (control terminal in the figure). The controller 4 performs processing by driving the vapor deposition apparatus 1 in accordance with the processing command (S6, S106, S107).

  When the processing of the convex surface is completed, the controller 4 transmits a processing history including the actually set processing conditions (parameters) and completion time to the management terminal computer 6, and the management terminal computer 6 sets the processing conditions from the controller 4 to the lot. The information is transmitted to the management server 5 in association with the number (S108). The management server 5 collects the tray IDs collected as a group of lots in the lot grouping process (S101, S102) by the lot numbers (lot numbers in the vapor deposition process) set in S105 and receives them from the management terminal computer 6. The lot number and processing conditions are accumulated as the processing history of the convex surface deposition process for each tray ID.

  When the convex surface processing is completed, each lens 12 of the dome 1A is again accommodated in the cleaning rack 8 and transferred to the cleaning device 3 for cleaning (S7, S8, S109). When the cleaning is completed, the lens 12 accommodated in the cleaning rack 8 is transferred again to the dome 1A, and the concave surface is prepared for processing (S9, S110).

  When the lens 12 for processing the concave surface is transferred to the dome 1A, the management terminal computer 6 performs a concave surface process movement process (S10 in FIG. 3) to check the processing history for each lens 12 (S111). When the concave surface processing is completed, the management terminal computer 6 issues a lot number to the management server 5. Based on the lot number, the management server 5 detects that the processing of the concave surface is performed.

  Then, the management terminal computer 6 transmits a processing command necessary for this concave surface processing to the controller 4 (control terminal in the drawing) based on the processing information acquired from the management server 5, and the controller 4 performs vapor deposition according to the processing command. Processing is performed by driving the apparatus 1 (S11, S112, S113).

  When the processing of the concave surface is completed, the controller 4 transmits a processing history including actually set processing conditions (parameters) and completion time to the management terminal computer 6, and the management terminal computer 6 sets the processing conditions from the controller 4 to the lot. The information is transmitted to the management server 5 in association with the number (S114). The management server 5 accumulates the lot number and the processing conditions received from the management terminal computer 6 as the processing history of the concave surface deposition process for the tray ID for which the lot number notification (S111) has been made.

  Thereafter, as shown in FIG. 3, it is determined whether or not the water repellent coating has been executed in the vapor deposition step (S12). When the water repellent coating is performed, the water repellent coat is inspected (S13). ) If the water-repellent coat passes the inspection, the process is terminated. If the water-repellent coat fails, the process returns to S7 and the water-repellent coat is performed again. The water repellent coating is inspected to determine whether the deposited water repellent coat satisfies a preset standard.

  Thus, the formation of the convex and concave vapor-deposited films is completed, and the lot of the group is released. The lens 12 for further forming the vapor deposition film returns to S101 again to form the vapor deposition film in the next lot.

  Lot cancellation is a step of returning the plurality of lenses 12 accommodated in the dome 1A to the original tray 10 (S15).

  Hereinafter, details of each process executed by the management terminal computer 6 will be described.

<Convex surface movement process>
Next, the convex surface process moving process performed in S105 of FIG. 2 and S5 of FIG. 3 will be described with reference to the flowchart of FIG. The flowchart of FIG. 4 is started by an operator or an administrator at the time of transfer from the cleaning rack 8 shown in S4 of FIG. 3 to the dome 1A.

  First, in S21, the tray ID of the lens 12 accommodated in the dome 1A is read from the barcode 111 of the work instruction sheet 11 using the barcode reader 61.

  In S22, the read tray ID is transmitted to the management server 5, and the lens information, the processing information, and the processing history are requested and read.

  In S23, when there are a plurality of sets of lenses 12, it is determined from the processing information acquired from the management server 5 whether the type and processing conditions of the deposited film are the same. In step S31, the fact that processing cannot be performed in one lot is displayed on the display device of the management terminal computer 6, a warning is issued, and the processing ends.

  In S24, it is determined from the processing history read from the management server 5 whether or not the convex surface has already been processed. If a convex deposition film has already been formed, the process proceeds to S28, and if not, the process proceeds to S25.

  In S25, in order to process with the same lot, it is determined whether reading of tray ID accommodated in the dome 1A was completed. This determination may be made by the operator operating the management terminal computer 6. If completed, the process proceeds to S26, while if the tray ID is still input, the process returns to S21.

  In S26, a lot number composed of a serial number set in advance is set, and the name or code of the person in charge who performs the work is set. Then, these lot numbers and names are transmitted to the management server 5, and it is set that the convex surface is processed with the set lot number for each tray ID. The lot number may be issued by the management server 5. In this case, the management terminal computer 6 may request and obtain the convex lot number from the management server 5.

  Next, in S27, processing conditions necessary for processing the convex surface are extracted from the processing information read in S22 and transmitted to the controller 4 as a processing command. The controller 4 executes the formation of a deposited film on the lens 12 of the dome 1A in response to this processing command.

  On the other hand, if the convex surface has already been processed in the determination of S24, the process proceeds to S28 to determine whether or not the vapor deposition film to be formed is the same vapor deposition film. If it is not the same vapor deposition film, it will progress to S29 and will warn with a display apparatus etc. that a some vapor deposition film (multicoat) will be formed, then it will progress to S25 and will perform the above-mentioned processing.

  On the other hand, if it is determined in S28 that the same vapor deposition film is the same, the process proceeds to S30 to warn that the vapor deposition film process is duplicated, and the display device is configured to skip the convex surface process and proceed to the concave surface process. Display. In this case, S6 to S9 in FIG. 3 are canceled and the process proceeds to the concave surface process moving process of S10.

  The controller 4 drives the vapor deposition apparatus 1 based on the processing command transmitted by the management terminal computer 6 in S27 to form a vapor deposition film on the convex surface of the lens 12 placed on the dome 1A.

  When the processing is completed, the controller 4 transmits the processing conditions to the management terminal computer 6 as described above, and the management terminal computer 6 transmits the processing conditions received in association with the lot number to the management server 5 as the processing history. Then, the processing history of the convex surface of each tray ID is added.

  By the above processing, it is possible to prevent the lenses 12 having different processing conditions from being mixed in the lot, and further prevent the same processing from being performed repeatedly from the processing history of each lens 12 acquired from the management server 5. Can do.

<Concave process moving process>
Next, the concave surface process moving process performed in S111 of FIG. 2 and S10 of FIG. 3 will be described with reference to the flowchart of FIG. The flowchart of FIG. 4 is started by an operator or an administrator at the time of transfer from the cleaning rack 8 shown in S9 of FIG. 3 to the dome 1A.

  First, in S <b> 41, the tray ID of the lens 12 accommodated in the dome 1 </ b> A is read from the barcode 111 of the work instruction sheet 11 using the barcode reader 61.

  In S42, the read tray ID is transmitted to the management server 5, and the lens information, the processing information, and the processing history are requested and read.

  In S43, when there are a plurality of sets of lenses 12, it is determined from the processing information acquired from the management server 5 whether the type and processing conditions of the deposited film are the same. In step S52, the fact that processing cannot be performed in the same lot is displayed on the display device of the management terminal computer 6, a warning is issued, and the processing ends.

  In S44, it is determined from the processing history read from the management server 5 whether or not the convex surface has already been processed. If the convex deposition film has already been formed, the process proceeds to S45. On the other hand, if the convex deposition film has not yet been formed, the necessary processing has not been completed. A warning is issued and the process is terminated.

  Next, in S45, it is determined from the machining history read from the management server 5 whether or not the concave surface has already been machined. If the concave deposition film is not already formed, the process is a new process, and the process proceeds to S46. On the other hand, if the concave deposition film is already formed, the process proceeds to S49, and the confirmation described later is performed.

  In S46, it is determined whether the reading of the tray ID accommodated in the dome 1A is completed for the plurality of lenses 12 processed in the same lot. This determination may be made by the operator operating the management terminal computer 6. If completed, the process proceeds to S47, but if the tray ID is still input, the process returns to S41.

  In S47, a lot number composed of a serial number set in advance is set, and the name or code of the person in charge who performs the work is set. Then, these lot numbers and names are transmitted to the management server 5, and it is set to process the convex surface with the lot numbers set for the respective tray IDs. The lot number may be issued by the management server 5. In this case, the management terminal computer 6 may request and acquire the concave lot number from the management server 5.

  Next, in S48, processing conditions necessary for processing the concave surface are extracted from the processing information read in S42, and transmitted to the controller 4 as a processing command. The controller 4 executes the formation of a deposited film on the lens 12 of the dome 1A in response to this processing command.

  On the other hand, if the concave surface has already been processed in the determination of S45, the process proceeds to S49, and it is determined whether or not the vapor deposition film to be formed is the same vapor deposition film. If it is not the same vapor deposition film, it will progress to S50 and will warn with a display apparatus etc. that a some vapor deposition film (multi-coat) will be formed, then it will progress to S46 and will perform the above-mentioned processing.

  On the other hand, if it is determined in S49 that the vapor deposition films are the same, the process proceeds to S51 to determine whether the vapor deposition film is reprocessed. If it is reprocessing in case of failure or inspection failure, the process proceeds to S46, and the concave surface is evaporated as usual. On the other hand, if it is determined in S51 that the processing is not reprocessing, a message indicating that processing cannot be performed in the same lot is displayed on the display device of the management terminal computer 6, a warning is issued, and the processing is terminated.

  The above processing prevents the lenses 12 having different processing conditions from being mixed into the lot. Further, the processing history of each lens 12 acquired from the management server 5 indicates that the lens 12 or the concave surface has not been subjected to the deposition process of the convex surface. It is possible to prevent the same processing from being repeated. However, the formation of the same vapor deposition film is permitted for defect correction.

  And the controller 4 drives the vapor deposition apparatus 1 based on the process command which the management terminal computer 6 transmitted by said S48, and forms a vapor deposition film on the convex surface of the lens 12 mounted in the dome 1A.

  When the processing is completed, as described above, the controller 4 transmits the processing conditions to the management terminal computer 6, and the management terminal computer 6 transmits the processing conditions received in association with the lot number to the management server 5 as processing history, Add processing history of concave surface of each tray ID.

  By the above processing, it is possible to prevent the lens 12 having different processing conditions from being mixed in the lot, and further determine whether the processing of the concave surface is valid from the processing history of each lens 12 acquired from the management server 5. Therefore, it is possible to prevent the processing of the previous process from being completed or the same processing from being performed repeatedly.

  As described above, in the vapor deposition step, the processing history is accumulated in the management server every time processing of the convex surface and the concave surface of the lens 12 is completed, and when starting processing, the lens 12 is referred to while referring to the processing history. By determining whether or not can be incorporated into the same lot, it is possible to prevent the loss or overlap of deposited films or incorrect setting of processing conditions, and greatly improve the productivity in lens manufacturing. Can do it.

  Furthermore, in the vapor deposition process of the lens 12, many coatings are often applied, and even when the same vapor deposition film is formed, the processing conditions are different between the convex surface and the concave surface. Since the setting of the machining conditions is acquired from the management server 5 each time, it is possible to avoid setting mistakes when an operator inputs the machining conditions as in the past, and to suppress the occurrence of defective products. .

  In addition, in the convex surface movement process and the concave surface movement process, when forming a plurality of vapor deposition films respectively, a warning is issued. It is possible to reliably prevent the vapor deposition films from being formed in a duplicated manner and to prevent a necessary vapor deposition film from being lost.

  Further, the management server 5 and the controller 4 of the vapor deposition apparatus 1 are connected via a management terminal computer 6 so that the management terminal computer 6 is connected to the manufacturing management system (management server 5) side and the manufacturing apparatus side control device (controller). 4) Since it is configured to control communication with the manufacturing apparatus, it is not necessary to add software for communicating with the manufacturing management system to the control apparatus on the manufacturing apparatus side, and the existing manufacturing apparatus can be used, resulting in excessive capital investment. Can be prevented.

  In particular, when diverting an existing manufacturing apparatus, even if the control apparatus of the manufacturing apparatus does not have a network interface such as a LAN, the management terminal computer 6 is connected with a serial port (such as RS232C) provided in a general control apparatus. Since this is easy, the management terminal computer 6 can be used as an interface between the manufacturing management system and the manufacturing apparatus, and the two functions of monitoring the processing consistency in the vapor deposition process can be performed by a single computer. The increase in the number of terminal devices can be suppressed.

  In the above embodiment, the determinations of S23, S24, S25, S28 of FIG. 4 and S43, S44, S45, S46, S49, S51 of FIG. 5 are performed by displaying a message on the display device of the management terminal computer 6. It may be performed based on the input of the operator or the administrator.

Second Embodiment
FIG. 6 shows the second embodiment, and the surface of the lens 12 shown in FIG. 3 of the first embodiment which is rejected when the water repellent coating test fails. In this case, the vapor deposition process is performed again, and the other configurations are the same as those in the first embodiment.

  In FIG. 6, S1 to S15 are the first embodiment, so redundant description will not be given.

  In S13, the water-repellent coat is inspected. If it is rejected in S14, it is determined in S69 which one of the convex surface and the concave surface is rejected. If it is a convex surface, the process proceeds to S59. If so, the process proceeds to S64.

  In the process of re-depositing the convex surface, the lens 12 is moved from the dome 1A of the vapor deposition apparatus 1 to the cleaning rack 8 for cleaning (S59, S50), and then the lens 12 is transferred to the dome 1A of the vapor deposition apparatus 1 (S61). Then, the convex surface moving process is performed in S62, and the processing conditions are set. In step S63, a water repellent coating is deposited again on the convex surface. Here, the convex surface moving process of S62 is a process to which a logic for determining whether or not the process is a reprocess as shown in S51 of FIG. 5 after adding YES in S28 of FIG.

  When the deposition of the convex water-repellent coat is completed, the process proceeds to S13 and the inspection is performed again.

  On the other hand, when the concave water-repellent coating is unacceptable, the lens 12 is moved from the dome 1A of the vapor deposition apparatus 1 to the cleaning rack 8 for cleaning (S64, S65), and then the lens 12 is removed from the vapor deposition apparatus 1. After the transfer to the dome 1A (S66), the concave surface moving process is performed in S67, and the processing conditions are set. In step S68, a water repellent coating is deposited again on the concave surface.

  In this way, by configuring a loop that performs reprocessing based on the inspection results, it is possible to prevent failure in later processes (final audits, etc.) and to reduce the time required for correction from occurrence of defects. By doing so, the overall efficiency of lens manufacturing can be improved.

  In the above embodiment, an example in which the present invention is applied to the vapor deposition process has been described. However, the present invention can be applied to a lens molding process, a dyeing process, a dip coating process, and the like.

  Moreover, although the example applied to the lens for spectacles was shown in the said embodiment, it applies to the manufacturing system of lenses (for example, optical drives, such as DVD-ROM and CD-ROM, a camera lens, etc.) of other optical systems. You can also

  In the above-described embodiment, the tray ID, which is the lens identifier, is attached to the work instruction sheet 11, but although not shown, the identifier is stored in an IC card or the like having a non-volatile memory, and the work instruction sheet 11. Instead of this, this IC card may be attached to the tray 10.

  Moreover, in the said embodiment, although the management terminal computer 6 and the management server 5 were connected by the network, these management terminal computers 6 and the management server 5 may be comprised with the same computer.

  As described above, according to the present invention, since the lens is processed while referring to the processing history while ensuring traceability in the lens manufacturing process, the present invention can be applied to a spectacle lens manufacturing system with excellent productivity. Can do.
