The present invention relates to a manufacturing system according Microfactory desktop type comprising a plurality of devices to be driven on the basis of a predetermined procedure.
[0002]
[Prior art]
As it is said to be an era of individualization and differentiation, demands and preferences of consumers are becoming increasingly diverse without knowing where to stop, and it is no longer possible for manufacturers to ignore those demands and preferences. As a result, it is becoming increasingly necessary to produce a variety of products in small quantities.
[0003]
On the other hand, the progress of technology is steadily progressing, and for manufacturers, not only high-mix, low-volume production, but also the development of more precise and accurate products, the consumers are demanding more precise and accurate products. Yes.
[0004]
However, in the current manufacturing system, when a customer's needs are heard and an attempt is made to meet the needs, the manufacturer develops a product that meets the needs, produces a product that meets the needs, and then demands it. Even if a product that meets the needs of the customer can be developed, a considerable amount of time and effort from product development to sales, as well as logistics problems and products that carry the product to the customer are temporarily stored. If you had a place problem etc.
[0005]
By the way, the Ministry of International Trade and Industry's Institute of Industrial Science and Technology's machine technology research institute of industrial technology science and technology research and development project "micromachine technology", the processing and assembly of small parts combining a micromachine tool and manipulator as shown in Fig. 1 A possible desktop type (desktop) ultra-small production factory, that is, the world's first machining microfactory 10 was successfully operated (announced on October 6, 1999).

[0009]
The micro press 3 has a length of 111 mm, a depth of 66 mm, a height of 170 mm, a motor rated power of 100 W for press, a rated press load of 3 kN, a die set size of 30 × 40 × 52 mm, and a six-step progressive process combining punching and bending. Is possible.
[0010]
The micro transfer arm 4 has a maximum arm length of about 100 mm, 3 degrees of freedom of translation + 1 degree of freedom of rotation around the vertical axis, horizontal position accuracy of about 20 μm, power consumption of 45 W, a horizontal articulated mechanism and a parallel link mechanism. As a result, a compact mechanism and a wide operating area (within a circle with a diameter of about 200 mm) are realized, and a composite device having an object suction due to negative pressure + error absorption during assembly work + contact force sensing function is mounted at the tip.
[0011]
The two-finger microhand 5 has a hand body, a cylindrical shape with an outer diameter of 48 mm and a height of 65 mm, three driving piezoelectric elements for each finger inside, a working range of about 100 μm × 100 μm × 30 μm, and resolution of movement A wide range of positioning operations can be performed in combination with a stage mechanism (movable region 30 mm × 30 mm × 15 mm) under a microscope.
[0012]
Using these micromachines, we have already succeeded in trial manufacture of an ultra-compact pipette ball bearing having an outer diameter of 900 μm and an axial length of about 3 mm. That is, the lathe 1 is used to manufacture the rotating shaft, the milling machine 2 is used to form the bearing housing, and the press machine 3 is used to produce the cover of the punched housing. These parts are precisely positioned with a negative pressure gripping part in the assembly zone approximately 180 mm away from the machining zone. In the assembly zone, a ball, a rotary shaft, and a cover are attached to the housing by a two-fingered hand 5.

DETAILED DESCRIPTION OF THE INVENTION
Figure 3 is a schematic illustration of a micro-factory production system using a network of the Internet or the like of the present invention.
[0021]
The product developer 11 has a microfactory 10 unlike a conventional product manufacturer, and does not manufacture the product by himself. A portable portable micro factory 10 including a micro lathe, a micro milling machine, a micro press machine, a micro transport device, a micro assembly device, and the like is disposed in a store 12-14 such as a convenience store where various items are placed.
[0022]
The store in which the microfactory 10 is arranged can be anything that can be held or worn by a person and can be finely processed to suit the person. Various stores including stores are assumed, and when the microfactory 10 is placed in the store, it may be sold out or rented as a membership system.
[0023]
The microfactory 10 has at least an input unit and a display unit. However, the microfactory 10 may be directly automatically driven by data relating to a manufacturing procedure sent from a server, which will be described later. The computer has a control device and a computer for controlling the control device, and the computer includes storage means such as a ROM and a hard disk, and temporarily stores data relating to a manufacturing procedure sent from a server, which will be described later, in the storage means. Each device of the microfactory 10 may be automatically driven and controlled by a procedure.
[0024]
The computer is an ordinary computer having an input unit and a display unit, and may be a personal computer. The control mode of each device by the computer is the same as the control mode of a conventionally known machine tool. The precise control is performed by a conventionally well-known numerical control or the like.
[0025]
The computer is connected to the server 16 of the product developer 11 via the network, and the store clerk listens to the customer's requirements for the product, such as conditions and requests, and inputs them according to a predetermined format displayed on the display unit of the computer.
[0026]
The input signal is sent to the server 16 of the product developer 11 via the network. In this case, in the case where the network is limited to a predetermined area in addition to the Internet, for example, another network such as a LAN may be used, and the communication form is not limited to online (wired) and may be wireless. Further, the server may be any server as long as it can exchange information of the present invention as well as a server normally used in network communication.
[0027]
The product developer 11 inputs product manufacturing procedures according to the needs of the customers for various products from the input device of the computer 17 and stores them in the server 16.
[0028]
Further, the product developer 11 actually manufactures the product by using the manufacturing procedure stored in the server 16 by the microfactory 10, and further improves and improves the product according to the developer's eyes. Always upgraded.
[0029]
For example, if the microfactory 10 provided in each store is equipped with a computer, the computer receives and stores a manufacturing procedure as production information from the server 16 of the product developer 11, and based on the stored manufacturing procedure. The devices of the microfactory 10 are driven to manufacture products desired by customers. The store clerk sells the manufactured product by hand to the customer.
[0030]
Information once stored in the computer may be automatically deleted when the work is completed, or may be stored and used when manufacturing the same product. In any case, the store only needs to know the minimum maintenance of each device of the microfactory 10, and when something abnormal occurs in the microfactory 10, a person related to the product developer 11 visits and repairs. .
[0031]
FIG. 4 is a block diagram of the server. The server 16 includes an input / output unit 26 that controls input / output of signals sent from a computer connected to the micro factory 10 of each store via the network 30, and a signal sent from the computer of each store via the input / output unit 26. A data receiving unit 21 for receiving the data, and a data transmitting unit 22 for transmitting a manufacturing procedure meeting the needs of the customer as production information to the computer of each store via the input / output unit 26
[0032]
The server 16 also includes a data storage unit 24 storing data related to the manufacturing procedure developed by the product developer 11 and data related to the manufacturing procedure stored in the data storage unit 24 in response to access from the computer of each store. Has a data search unit 23 for searching for.
[0033]
Furthermore, the server 16 includes a data update unit 25 that is used when the product developer 11 improves an existing manufacturing procedure based on customer needs and the like.
[0034]
Next, the present invention will be described taking the spectacle store 12 as an example. If a customer comes to buy a contact lens, the store clerk examines the degree of myopia, hyperopia, or astigmatism of the customer's eyes.
[0035]
After the optometry, the store clerk attaches the contact lens to a predetermined position of the micro factory 10. In this case, an unprocessed contact lens may be used. However, in the case where a lens for nearsightedness or farsightedness is provided for each range, the processing time can be shortened by using the lens closest to the person as a result of the optometry.
[0036]
Next, the store clerk inputs the size of the contact lens as the customer's needs and the result of the optometry at a predetermined location on the display unit of the micro factory 10.
[0037]
Note that the contact lens dimensions are numbered for each type, and the number data is also entered in advance in the product developer's server to facilitate entry at the store.
[0038]
If a laser measuring instrument is provided as one of the devices of the microfactory 10 and the dimension of the attached contact lens can be automatically retrieved, for example, after the fine processing is performed once, the correction processing is performed again. It is very convenient when necessary.
[0039]
The signal is sent to the server 16 of the product developer 11 via the network 30 such as the Internet, and the signal sent to the server 16 is received by the data receiving unit 21 via the input / output unit 26 and the data The data is sent to the data search unit 23 via the reception unit 21.
[0040]
The data search unit 23 accesses the data storage unit 24 based on the sent search condition, and extracts data related to the manufacturing procedure corresponding to the sent search condition from the data storage unit 24.
[0041]
The extracted data relating to the manufacturing procedure is sent to the store as production information from the data transmission unit 22 and the input / output unit 26 via the network 30. For example, the computer is driven according to the manufacturing procedure sent to each device of the microfactory 10. Then, considering the dimensions of the contact lens, only the dimensions determined to meet the input conditions are removed, and if necessary, the contact lens is transported to the polishing machine by the transport arm. And polishing.
[0042]
After the processing is completed, the store clerk removes the contact lens from the microfactory 10, cleans and verifies the contact lens with the eyes of the customer, and executes correction processing again according to the procedure described above if necessary. Then, the completed contact lens is handed and sold to the customer as a product 15.
[0043]
The product 15 of the spectacle store 12 requires considerable precision for processing, but in many cases, simple processing is sufficient. Next, an example of the sports store 13 will be described.
[0044]
It is said that the flight distance and direction depend on the number of grooves, the size of the width, and the depth thereof, as many grooves are formed on the head surface of golf. However, this groove was formed in advance, and the golfer could not form this groove according to his preference.
[0045]
The sports store 13 includes the micro factory 10 and listens to the needs of the customer, and at the same time advises the shape of the groove from the standpoint of an expert, and determines the shape of the groove suitable for the customer.
[0046]
After determining the shape of the groove, the store clerk attaches a head without a groove to a predetermined position of the microfactory 10, and drives the number of grooves, width, and depth to be formed as production information into a predetermined position of the display unit of the computer. .
[0047]
The signal is sent to the server 16 of the product developer 11 via the network 30 such as the Internet as customer needs, and the signal sent to the server 16 is received by the data receiving unit 21 via the input / output unit 26. At the same time, the data is sent to the data search unit 23 via the data reception unit 21.
[0048]
The data search unit 23 accesses the data storage unit 24 based on the sent search condition, and extracts data related to the manufacturing procedure corresponding to the sent search condition from the data storage unit 24.
[0049]
The extracted data relating to the manufacturing procedure is sent from the data transmission unit 22 and the input / output unit 26 to, for example, a store computer via the network 30, and the computer is driven according to the manufacturing procedure sent to each device of the microfactory 10. Then, a groove that meets the input conditions is ground with respect to the attached head by using a micromilling machine or the like, and if necessary, the head is transported to a polishing machine by a transport arm to perform polishing.
[0050]
After the processing, the store clerk removes the head from the microfactory 10 and sells it as a product 15 to the customer.
[0051]
Thus, the required processing accuracy differs depending on the product. Therefore, the microfactory 10 used as a general-purpose machine is equipped with a standard control device, and the microfactory 10 used as a dedicated machine has an accuracy corresponding to the product to be processed. A control device having the above is provided.
[0052]
