Description

Description: TECHNICAL FIELD The present invention relates to an assembly part identification device in flow production.

[Conventional technology and its problems]

In the flow production, generally, an assembled substrate, for example, a substrate for electric products is accommodated in a tray and sequentially transferred on a belt conveyor. Various parts are sequentially assembled in each station during this transfer, but recently, so-called mixed flow production is being carried out, and in this production method, not the same product but the assembly substrate for different products is sequentially transferred. As a result, the parts are assembled in each station in the assembly base for each product, but the worker at each station should remember in advance what part should be assembled in which assembly base for which product. I was doing it, or I was looking at the manual and had installed the parts that should be installed at this station.

However, if there are many types of products displayed in the manual, or if there are many types of parts to be incorporated, it is difficult to memorize them all. Was very troublesome and took a long time.

[Problems to be solved by the invention]

The present invention has been made in view of the above problems, and even in mixed-flow production, a worker can quickly identify a component to be incorporated and assemble a necessary component into an assembly base to perform an assembly work quickly. An object of the present invention is to provide an assembly part identification device in flow production, which can greatly improve efficiency.

[Means for solving problems]

The above object is to drive at least a first antenna coil, a rectifier circuit that rectifies alternating current by an electromagnetic wave of a second frequency from the command device and the label printer received by the first antenna coil, and a rectified output of the rectifier circuit. A data read circuit, a data storage unit connected to the data read circuit for storing unique data, and a data storage unit connected to the data storage unit,
An assembly for generating an output for transmitting the contents of the data storage unit at a first frequency and incorporating an output circuit for providing the output to the first antenna coil is transferred along a predetermined transfer path. An oscillator circuit that is detachably attached to a base or a tray that houses the assembled base, generates an AC output of at least the second frequency, a second antenna coil connected to the oscillator circuit, and reads from the data storage unit. The electromagnetic wave, which is the output of the oscillation circuit, from the command device including a computer having a storage unit for storing embedded components corresponding to the data, and the assembly base or the assembly base. When the tray containing the is transferred to a predetermined station, the first antenna coil and the second antenna coil are electromagnetically coupled to each other so that the identification means is The data read circuit is operated by the rectified output of the flow circuit to read the specific data from the data storage unit, and the output circuit outputs the first data from the first antenna coil to the second antenna coil at the first frequency. And sends it to the command device so that the computer can cause the display means to display the component to be assembled into the assembly base body, and an operator at the predetermined station can see the display and display the component. Assembling was completed in the assembly base immediately before, and at each station along the predetermined transfer path, the parts to be assembled by each worker were incorporated in the assembly base by looking at the respective display means. The assembled substrate as a product or a tray containing the assembled substrate is transferred to the vicinity of the label printer, and the label printer includes at least an oscillation circuit and A computer having a third antenna coil connected to the vibration circuit and a storage unit for storing at least a model corresponding to the data read from the data storage unit, and the third antenna coil and the first antenna The content of the product is sent from the data storage section of the identifying means to the label printer side by electromagnetic coupling with the antenna coil, and the computer of the label printer issues a command to print at least the model of the product, This is achieved by an assembly part identification device in flow production, characterized in that a label for displaying at least the model of the assembly base is issued by a printer and is attached to a cardboard containing the assembly base.

[Action]

Identification means is attached to the assembly base body transferred along a predetermined transfer path or a tray containing the assembly base body,
Now, when it is transferred to a certain station, the first antenna coil receives the electromagnetic wave oscillating from the second antenna coil of the command device corresponding to this station by electromagnetic coupling, and activates the data reading circuit of this identifying means. Then, specific data is read from this data storage unit, and this data is, for example, a model number or model, which is the first antenna coil of the identification device and the second antenna coil which is electromagnetically coupled to this.
Transmit to the command device via the antenna coil. From the transmitted data, the computer displays the component to be incorporated at present by the display means. The worker corresponding to this station recognizes the part to be assembled by looking at it, and installs this part on the assembly base immediately before. As described above, since the worker corresponding to each station can immediately recognize the component to be incorporated in each station by the display means and the required component can be incorporated immediately, the assembly base body which has been assembled is completed. Since the label printer reads the model of, the label representing the model is issued, and the label is attached to the corrugated cardboard housing the assembled substrate, the production efficiency can be greatly improved.
