Description

A circuit board probe tester

technical field

The utility model relates to the field of circuit board testing, in particular to a circuit board probe tester.

Background technique

Mobile DVD is a kind of electronic device commonly used in our life. A mobile DVD consists of a movement, a display screen and a circuit board. The movement is used to read the disc data, and the circuit board is used to analyze the data and transmit the data to the display screen. Therefore, the circuit board as a data analysis carrier is very important. The traditional method of detecting whether the circuit board is good or bad is: use a wire to directly connect the movement, the display screen and the circuit board, and see if the display screen displays the contents of the disc normally, thereby judging the quality of the circuit board. This detection method is not convenient, and the circuit board must be reconnected with wires every time. The disassembly and installation of the circuit board is very cumbersome and time-consuming, which cannot meet the needs of fast production.

Utility model content

In order to solve the above problems, the utility model provides a circuit board probe tester, the specific technical scheme is as follows:

A circuit board probe tester, including a workbench, a disc-reading movement and a display screen, the display screen is installed on the front side of the workbench, the disc-reading movement is installed above the workbench, it also includes a pressing mechanism and a needle plate, The needle board is installed on the workbench, and the needle board is equipped with probes corresponding to the position of the circuit board. The circuit board to be tested is placed between the pressing mechanism and the needle board, and the pressing mechanism drives the test circuit board to contact the probes. , the probe is electrically connected with the display screen.

Preferably, the pressing mechanism includes a fixed plate, an L-shaped handle, a movable part, a pressing rod and a pressing plate, the fixed plate is vertically installed on the workbench, the short end of the L-shaped handle is hinged to the fixed plate, and the middle part of the L-shaped handle is The movable part is hinged at the end point, the movable part is hinged with the pressing rod, and the pressing rod is fixedly connected with the pressing plate.

Preferably, four pressure columns are arranged under the pressure plate.

Preferably, the workbench is provided with a probe control switch.

Beneficial effects of the utility model: when using the circuit board probe tester of the utility model, the optical disc is placed in the disc reading core in advance, the pressing mechanism drives the circuit board to contact the probe, and the data read by the disc reading core is transmitted to The circuit board, the circuit board then transmits the data to the display screen, and judges the quality of the circuit board through whether the display screen displays the contents of the disc normally. The detection method is simple and effective, and the loading and unloading of the circuit board takes a short time, greatly increasing the detection speed Very good to meet production needs.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:

As shown in Figure 1, a circuit board probe tester includes a workbench 1, a disc reading movement 2 and a display screen 3, the display screen 3 is installed on the front side of the workbench 1, and the disc reading movement 2 is installed on the workbench 1, it also includes a pressing mechanism 4 and a needle board 5, the needle board 5 is installed on the workbench 1, the needle board 5 is provided with probes corresponding to the position of the circuit board 6, and the circuit board 6 to be tested is placed on the Between the pressing mechanism 4 and the needle plate 5, the pressing mechanism 5 drives the test circuit board 6 to contact with the probes. The disc reading core 2 is used as a data source for reading disc data, the disc data is transmitted to the circuit board 6, the circuit board 6 decodes the data and transmits the decoded data to the display screen 3, and the display screen 3 displays the content of the disc.

The pressing mechanism 4 includes a fixed plate 41, an L-shaped handle 42, a movable part 43, a pressure bar 44 and a pressing plate 45, the fixed plate 41 is vertically installed on the workbench 1, and the short end of the L-shaped handle 42 is hinged to the fixed plate 41, the middle end of the L-shaped handle 41 is hinged with the movable part 43, the movable part 43 is hinged with the pressure rod 44, the pressure rod 44 is fixedly connected to the pressure plate 45, and there are 4 pressure columns under the pressure plate 45, and the 4 pressure columns are pressed against the circuit board 6 around. Rotate the L-shaped handle 42 to drive the movable part 43 to move up and down. The movable part 43 drives the pressure rod 44 to move up and down.

The working principle of the utility model: place the circuit board 6 above the needle plate 5, turn the L-shaped handle 42 to drive the movable part 43 to move down, the movable part 43 drives the pressing rod 44 to move down, and the pressing rod 44 drives the four upper pressing plates 45 The pressure column presses the circuit board 6, the circuit board 6 is in full contact with the probe on the needle plate 5, turn on the probe control switch 7, and observe whether the display screen 3 displays the contents of the disc normally, so as to judge whether the circuit board 6 is good or not. The disc data read by the core 2 is transmitted to the circuit board 6, and the circuit board 6 decodes the data and transmits the data to the display screen 3, and observes whether the display screen 3 displays the contents of the disc normally, thereby judging whether the circuit board 6 is good or not.

The above content is a further detailed description of the utility model in conjunction with specific preferred embodiments.
