[0025] See Figures 1 to 3 , a circuit board detection tooling, comprising: a workbench 100, the workbench 100 is provided with a rectangular test area, the test area is provided with a diagonal line, the workbench 100 is provided with a first clamping member 110 and a second clamping member 120 that are spaced along the diagonal line, the first clamping member 110 is fixedly arranged relative to the workbench 100, the second clamping member 120 can move relative to the workbench 100, the second clamping member 120 is connected with a moving block 130, the moving block 130 is threadedly connected with a driving screw 140, the projection of the axis of the driving screw 140 coincides with the diagonal line, when the driving screw 140 rotates, the moving block 130 drives the second clamping member 120 to move along the diagonal line, so that the first clamping member 110 and the second clamping member 120 jointly clamp a rectangular circuit board.

[0026] For the circuit board detection tooling with the above structure, when in use, first abut the rectangular circuit board against the first clamping member 110 and make the diagonal line of the circuit board coincide with the diagonal line of the test area, and then rotate the driving screw 140 to make the second clamping member 120 move along the diagonal line of the test area, so that the first clamping member 110 and the second clamping member 120 can respectively press against two opposite diagonal corners of the circuit board, which is beneficial to quickly achieve the effect of clamping and fixing the circuit board, and further beneficial to adapting to the fixing of circuit boards of different specifications, and also beneficial to quickly disassembling the circuit board by moving the second clamping member 120 later, thus avoiding the problem that it is difficult to disassemble the circuit board placed in the sink in the past. Among them, adopting the way of the driving screw 140 is beneficial to improving the adjustment accuracy of the movement of the second clamping member 120, so as to improve the effect of the second clamping member 120 pressing against the circuit board.

[0027] See Figures 1 to 3, Further, the first clamping member 110 includes two first folding plates 111 that are vertically connected. The first folding plates 111 are disposed on the workbench 100. The second clamping member 120 includes two second folding plates 121 that are vertically connected. At least one of the second folding plates 121 is detachably connected to the moving block 130. Specifically, the two first folding plates 111 are vertically connected, and the two second folding plates 121 are vertically connected, such that the two first folding plates 111 and the two second folding plates 121 respectively form two corners of a rectangle. Moreover, the second clamping member 120 can move along the diagonal of the test area to adjust the size of the enclosed rectangle, thereby being able to adapt to the fixation of circuit boards of different specifications, which is conducive to improving the versatility of the device. It can be understood that the first folding plate 111 and the second folding plate 121 can also be set to one, and the first folding plate 111 and the second folding plate 121 are arranged in parallel, thus forming two opposite sides of a rectangle, and the effect of quickly fixing the circuit board can also be achieved.

[0028] See Figures 1 to 3 , Further, the moving block 130 is provided with two mounting plates 131. The extending directions of the two mounting plates 131 are perpendicular to each other. The mounting plates 131 are provided with mounting holes, and the second folding plates 121 are provided with waist-shaped holes 122 that are parallel to their length directions. The mounting holes and the waist-shaped holes 122 are connected by a bolt assembly. Specifically, the bolt assembly includes a bolt and a nut. The bolt passes through the mounting hole and the waist-shaped hole 122, and the nut is screwed tightly to the second folding plate 121, such that the second folding plate 121 can be clamped and fixed relative to the mounting plate 131. When it is necessary to adjust the position of the second folding plate 121, only the nut needs to be loosened, such that the second folding plate 121 can move relative to the bolt through the waist-shaped hole 122, which is conducive to subsequently changing the positions of the two second folding plates 121 to form rectangular corners of different sizes. In some embodiments, the second folding plate 121 can also be fixed to the moving block 130 by magnetic attraction, which will not be elaborated here.

[0029] See Figures 1 to 3 , Further, the moving block 130 is provided with two long grooves 132 that are perpendicular to and communicate with each other. Each long groove 132 is parallel to the adjacent mounting plate 131. Each second folding plate 121 is fitted into the corresponding long groove 132, thereby forming a guiding and limiting effect on the movement of the second folding plate 121, which is conducive to preventing the second folding plate 121 from shifting during the movement and affecting the effect of clamping the circuit board.

[0030] See Figure 3, Further, the lower end surface of the second folding plate 121 includes a first end surface and a second end surface arranged in a stepped manner. The workbench 100 includes a placement plate 101. The first end surface abuts against the upper end surface of the placement plate 101, and the second end surface abuts against the bottom wall of the long groove 132. Specifically, the circuit board is placed on the placement plate 101, and the first end surface abuts against the upper end surface of the placement plate 101, thereby preventing a gap between the second folded edge and the placement plate 101 from affecting the fixation of the circuit board, which is beneficial for the side wall of the second folding plate 121 to better abut against the circuit board subsequently.

[0031] See Figure 1 , Further, the workbench 100 is provided with a cavity, the driving screw 140 is built in the cavity, the workbench 100 includes a placement plate 101, and the placement plate 101 is provided with a long hole 102 communicating with the cavity. The moving block 130 is slidably matched with the long hole 102, thereby preventing the moving block 130 from rotating relative to the workbench 100, which is beneficial for the second folding plate 121 to accurately move to press against the circuit board. It can be understood that two mounting seats are built in the cavity, the driving screw 140 is rotatably arranged between the two mounting seats, the driving screw 140 is provided with two limit blocks, and one of the mounting seats is located between the two limit blocks. The limit blocks are used to limit the movement of the driving screw 140, so that the driving screw 140 can only rotate relative to the workbench 100.

[0032] See Figure 1 and Figure 2 , Further, one end of the driving screw 140 is connected with a rotating handle 141, and the rotating handle 141 is located outside the workbench 100, so as to facilitate people to drive the driving screw 140 to rotate through the rotating handle 141, which is beneficial for people to controllably adjust the movement of the second clamping member 120.

[0033] See Figure 1 and Figure 2 , Further, a column 200 is provided on the side wall of the workbench 100. The upper end of the column 200 is horizontally connected with a mounting column 210. The mounting column 210 is provided with a telescopic cylinder 220. The telescopic end of the telescopic cylinder 220 is downwardly connected with a lower pressing plate 230. The lower pressing plate 230 is arranged opposite to the test area, so as to clamp the circuit board in the up and down direction through the lower pressing plate 230, further improving the fixing effect of the circuit board.

[0034] See Figure 2 , Further, a probe 231 is arranged on the lower surface of the lower pressing plate 230. The probe 231 is used to contact the surface parts of the circuit board. Specifically, through the downward movement of the lower pressing plate 230, the probe 231 presses down to detect the circuit board, so as to check the open and short circuit conditions of individual components and each circuit network of the circuit board.

[0035] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.
