Description

Harness product assembly state improted good, badness examination mounting}

The present invention is a device for inspecting good quality and poor assembly status of harness products, and in particular, it is easy to use as a standalone equipment in the production process of harness products of LVDS and cables used in home appliances, TVs, monitors, computers and digital products. It is a method of inspecting and manufacturing harness products of various types of pins and producing and inspecting defects of the harness products at high speeds. In general, TVs, monitors, and computers are composed of multiple boards.

There are a number of harness products for the electrical connection between the board and the board. In addition, such a harness product may have a plurality of signal points, and includes a communication protocol for internal communication and data exchange. can do. Manufacturers of such harness products need equipment to check the quality of goods and defects by inspecting all the products in the production process.

Conventional wiring harness wiring error inspection equipment inputs and outputs data into ROM pack type EPROM, which makes the operation of the producer complicated, the production of inspection circuit difficult, and the jig constituting the circuit should be corrected every time the circuit design is changed. There is a hassle to do.

In addition, conventionally, a single product is inspected to make a single inspection jig to inspect a single product. Therefore, it is costly and time-consuming, and an inefficient method of soldering a circuit configuration to the inspection jig one by one.

Moreover, the conventional wiring error inspection equipment has the disadvantage that the error of the cable such as disconnection, short, short circuit, out-of-circuit input, etc. is expressed only one point, and informs the producer when it is in error. The state was unmarked, and complex circuits such as increasingly complex cables and diode circuits could not be examined.

In addition, since there is no built-in test probe to check when a specific circuit is incorrectly manufactured, a separate electric tester has to be used. On the other hand, conventional test equipment is basically a one-chip microcomputer. Systematic use of the processor (Onechip Microprocessor)

In addition, there are many software restrictions, which causes considerable inconvenience in the manufacture of test circuits and test plates (jigs), and the disadvantages of low production efficiency. PC-based products are considered as components, It is inadequate as a harness inspection equipment that requires weak and simple production equipment. It is expensive to manufacture and unreasonable for installation in a small environment.

Assume that the assembly state is bad, the generation of goods is illustrated below.

1) Incorrect wiring: When pin 1 of input terminal is connected to pin 10 of output terminal.

2) Short: When pin 1 of input terminal is combined with pin 10 of output terminal.

3) Disconnection: When pin 1 of the input terminal is not connected.

4) Uninserted: When the terminal of pin 1 of the input terminal is pushed out of the housing.

5) Complete error: When the input and output terminals are replaced.

6) Momentary disconnection: In case pin 1 of input terminal is connected and dropped.

If all of these detection conditions are satisfied and there is no error in the harness product, it is OK and counts the production inspection results, removes the harness product from the main jig, and at the same time, the harness product is assembled in good condition. Inspection equipment
