BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a universal fixture for testing printed circuit boards for measuring electronic parts (electronic circuits) and circuit conditions, etc., which are implanted (mounted) on a printed circuit board (PCB) to be tested and produced.

In more detail, the fixture is provided on the upper side of the fixing plate installed inside the housing so that it can be moved back and forth by the air cylinder, and on the upper side of the movable base, the fixture is capable of opening and closing the cover in the main body. One side of the circuit board is installed by fixing the main anchor block so that the fixture can be moved through the guide line on the center line to see through from the front while maintaining the nut hole at equal intervals on the entire surface of the cover Support the (reference plane) and install the mounting blocks on the front left and right and front of the main set block to support the outer surface of the circuit board placed on the main set block. The pin block that can hold the corners can be used for the main set block and the stationary block. It is installed on the cover, and the recognition camera is installed at the upper center of the fixture, and the recognition dog is installed at the corner of the circuit board placed in the fixture so that the position of the printed circuit board placed in the fixture can be accurately detected by the recognition camera. Install the pin block on the rear of the fixture, but each terminal fixed to the pin block is connected to the terminal connected to the terminal surface of the printed circuit board using the connector and connecting line, and the test pin (measurement probe) is located behind the fixed base. Printed circuit board inspection, where the installed probe plate is installed, and the fixture on which the circuit board is placed is retracted together with the moving base so that each terminal of the pin block installed at the rear of the fixture is in contact with the test pin (measurement probe). We want to provide a universal fixture for you.

Conventionally, a fixture for arbitrarily measuring a printed circuit board that is tested and produced as in the present invention has not been proposed, but various inspection apparatuses (fixtures) for measuring a large quantity of printed circuit boards have been proposed. .

As such to measure and inspect the printed circuit board produced in large quantities, the Korean Utility Model Publication No. 2000-2000 Publication No. 2000-54963 and the Patent Registration No. 154232 are known, using a camera Domestic patent registration No. 269151 is known to perform the inspection.

Korean Utility Model Publication No. 2000-2000, "Main PCB Inspection Device with Grounding Bar of Recording Prevention Switch," has a PCB on which electronic components are mounted on the upper side of the main body on which a plurality of test pins are installed. While pressing the PCB with the spacer and the ground rod protruding from the pressing plate, the measurement is performed by pressing the PCB. However, the spacer and the ground rod protruding from the bottom of the pressing plate are pressed against the upper surface of the PCB. If the pressure is not uniformly distributed, there is a problem that a poor contact occurs, and since the spacer and the ground rod of the pressure plate is in direct contact with the PCB, there is a problem that damage such as the PCB is broken.

[0008] The "PCB inspection apparatus" of the Patent Publication No. 2000-54963 performs an inspection in a state in which a substrate (PCB) on which a circuit element (electronic component) is mounted is placed on a test pin provided on a support, and performs inspection. The magnetic field generating unit is provided on the upper side of the substrate to generate a sine wave (magnetic field) generated by the sinusoidal wave generating unit through the coil, so that the inspection can be performed from the upper side of the substrate toward the substrate during the inspection. There is a concern that an error may occur in the inspection by the magnetic field, and when the magnetic field extends to the measuring device, an error occurs in the measuring system itself, and thus, there is a problem in that the measurement and inspection cannot be precisely performed at the source.

Patent registration No. 154232 "Vacuum suction type printed circuit board inspection apparatus", a fixture with a test pin is installed on the inner side of the body with a vacuum suction connector, the support plate of the flexible material and the PCB provided with an auxiliary plate on the upper side of the body In order to hold the rest in order to hold the PCB in the seat, the vacuum suction connector of the body in the vacuum suction air inside the body through the vacuum suction connector, the PCB placed in the rest of the vacuum is sucked into the lower side while compressing the support As the electronic parts of the PCB move to be in contact with the test pin of the fixture, the inspection is performed, but the inspection is performed by moving the PCB to the lower side by vacuum suction. Therefore, when the vacuum suction input becomes weak, the PCB cannot be lowered sufficiently. There is a problem that the inspection can not be performed smoothly because it is impossible to carry out or the measurement is performed poorly. When the strong suction force to vacuum suction, and the PCB is the deformation the contact failure of the test pin, and thus there is a problem that can not be accurately check the PCB.

Patent Registration No. 269151 "PCB Inspection Device" stops a PCB supplied by a supply conveyor at an inspection conveyor, and operates the PCB stopped at the inspection conveyor up and down by a vertical operation device to focus on a camera installed on the upper side. When the camera is in focus, the PCB is moved by X and Y axes by the XY actuator together with the up and down actuator, and the camera moves to the X and Y axes in order to shoot a predetermined pixel with the camera. The test is performed by visual inspection while displaying on the monitor or by comparing with the standard image already input, but this is because the inspection of the electronic parts installed on the PCB must be carried out by camera. There is a problem that takes a long time, and each electronic component is moved while the camera or PCB is sequentially moved (XY). Since it is taken with a camera and compared with the pattern, it is only to check whether the electronic component is inserted or not. Therefore, whether the electronic component installed on the PCB is genuine and that the PCB works normally. There is a problem that can not be checked at all.

In particular, these conventional inspection devices are a device to measure and test the circuit board produced in large quantities, there is a problem that can not be measured and tested by randomly discharging the test and mass produced circuit board.

The present invention is to provide a universal fixture for testing a printed circuit board that can solve the above problems.
