Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, in order to disclose a circuit board integrated detecting device in the embodiment of the present application, the detecting device is composed of a detecting table 11, a positioning hole 12, a positioning pin 13, a detecting plate 21, a detecting base 22, a detecting probe 23, a detecting terminal 24, and the like, specifically, the detecting table 11 is placed on a workbench and is used for fixing a circuit board to be detected.

Referring to fig. 2, positioning holes 12 are uniformly distributed on a working surface (i.e., a top surface) of the inspection stage 11, the positioning holes are arranged in a matrix form of MxN, and M and N are natural numbers greater than zero. The positioning holes 12 serve to fix the positioning pins 13. The first end of the positioning pin 13 is inserted into the positioning hole 12, and the second end is located outside the positioning hole 12.

The number of the positioning pins 13 can be three or four, and certainly, the positioning pins 13 still need to be fixed according to the shape of the circuit board in the actual use process, if the shape of the circuit board is large, the number of the positioning pins 13 needs to be properly increased, so that the circuit board is prevented from being locally deformed in the detection process.

Referring to fig. 5, fixing grooves 135 are formed on the side surfaces of the positioning pins 13, and the edge of the circuit board can be inserted into the fixing grooves 135 and then fixed on the inspection table 11.

The detection plate 21 is slidably attached to the detection table 11, and specifically, the detection plate 21 is movable in directions toward and away from the detection table 11. Detection bases 22 are uniformly distributed on the working surface (namely, the bottom surface) of the detection plate 21, the detection bases 22 are arranged in a matrix form of MxN, and M and N are natural numbers larger than zero.

Referring to fig. 1 and 3, each of the inspection bases 22 is mounted with an inspection probe 23, and the inspection probe 23 is configured to abut against an inspection point on the circuit board and then transmit a signal to the inspection terminal 24.

The detection terminal 24 is a terminal storing a detection program and is connected with each detection probe 23 on the detection board 21, during the detection process, the detection terminal 24 will turn on or off the circuit where the detection probe 23 is located according to the built-in storage instruction, and then judge the condition of the circuit board according to the feedback electric signal.

The detection base 22 is connected to the detection plate 21 in a sliding manner, that is, the position of the detection base 22 can be changed in the vertical direction, and the purpose of this is to select a proper detection probe 23 to contact the circuit board to be detected.

It should be understood that in the actual testing process, not all the testing probes 23 need to contact the circuit board, and therefore, for different circuit boards, the corresponding testing base 22 needs to be pushed to move, so that the testing probes 23 corresponding to the testing positions on the circuit board can be extended.

In conjunction with a specific detection process, a worker first needs to select a fixing position according to the shape of the circuit board, then inserts the positioning pins 13 into the corresponding positioning holes 12, and then fixes the circuit board on the positioning pins 13.

Then, a part of the detection base 22 is pushed out from the detection plate 21 according to the detection request, and thus the preparatory process before detection is finished. In the detection process, the worker pushes the detection plate 21 to move towards the square close to the detection table 11 until part of the detection probes 23 contact with the circuit board, then the detection terminal 24 starts to execute the detection process, and after the detection is finished, the worker replaces the next circuit board and continues to repeat the detection process.

Referring to fig. 1, as a specific embodiment of the circuit board integrated detection device provided by the application, a limiting column 25 is additionally installed on the detection plate 21, and the limiting column 25 is used for abutting against the detection platform 11 to prevent the detection probe 23 from contacting the detection platform 11.

That is, the length of the limiting column 25 is greater than the length of the detection probe 23 when extending out, so that the bending or breaking of the detection probe 23 caused by the contact between the detection probe 23 and the detection platform 11 can be fundamentally avoided.

Referring to fig. 3, as a specific embodiment of the circuit board integrated detection device provided by the application, a guide hole 211 is formed in the detection plate 21, one end of the detection base 22 is inserted into the guide hole 211, and the matching manner between the detection base 22 and the guide hole 211 is interference fit, so that the detection base 22 can slide in the guide hole 211 by slightly pushing the detection base 22, and the use is more convenient.

Of course, bolt pushing could also be used.

Referring to fig. 4, as an embodiment of the circuit board integrated type detection device provided by the application, the positioning pin 13 is composed of three parts, namely a first short shaft 131, a second short shaft 132 and a screw 133, and the screw 133 is fixed on the second short shaft 132 and screwed into a threaded hole on the first short shaft 131.

This means that there is a gap between the first short shaft 131 and the second short shaft 132 and the width of the gap can be adjusted according to the actual use requirement, for example, when the edge of a certain circuit board is not fixed, the second short shaft 132 can be screwed off first, and the edge of the circuit board abuts on the first short shaft 131, and then the second short shaft 132 is screwed on the first short shaft 131.

Further, the working surfaces of the first stub shaft 131 and the second stub shaft 132 are provided with elastic pads 134, the working surface of the first stub shaft 131 refers to an end surface adjacent to the second stub shaft 132, and the working surface of the second stub shaft 132 refers to an end surface adjacent to the first stub shaft 131.

The resilient pads 134 function to prevent the edges of the circuit board from fraying or marking.

The positioning pins 13 are only provided with the grooves 131 and are shown in fig. 4, and the two positioning pins 13 are used in combination to fix the circuit board to be detected.

Referring to fig. 6(a) to 6(C), as a specific embodiment of the circuit board integrated detecting device provided in the application, the detecting probe 23 is plugged into the detecting base 22, that is, the detecting probe 23 can be replaced according to the actual detection requirement, for example, when a certain detecting point cannot be contacted, the detecting probe 23 of a special shape can be replaced to perform the detection.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
