[0080] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0081] like Figures 1 to 5 As shown, the embodiment of the present application provides a thrust test device 1000, which is used to perform a thrust test on the soldering firmness of electronic components soldered on a printed circuit board 2000. The thrust test device 1000 includes a coarse adjustment positioning device 100, a fine adjustment positioning device 200 and a testing device 300.

[0082] The aforementioned testing device 300 includes a thrust meter 50 for measuring the thrust of an electronic component.

The head of the thrust gauge 50 can be provided with a push head 51 protruding toward the direction of the aforementioned coarse adjustment positioning device 100. The protruding area of ​​the push head is much smaller than the area of ​​the head of the thrust gauge 50, so that the contact area between the thrust gauge 50 and the electronic components is greatly reduced. In addition, the side of the push head 51 facing the coarse adjustment positioning device 100 can be provided with a groove for clamping, aligning and positioning, so as to facilitate the clamping and positioning of the electronic components on the printed circuit board 2000. The push head 51 can be locked and fixedly connected to the screw rod 522 of the head of the thrust gauge 50 by a hexagonal nut 521 to prevent the push head 51 from tilting. The screw rod 522 can be straightened and arranged in the direction of the coarse adjustment positioning device 100.

[0083] The aforementioned coarse adjustment positioning device 100 includes a fixed plate 10, and an X-direction sliding component and a Y-direction sliding component arranged on the upper surface of the fixed plate 10 for driving the printed circuit board 2000 to slide along the X-direction and slide along the Y-direction, and a first clamping fixture 31 connected to the X-direction sliding component and a second clamping fixture 32 connected to the Y-direction sliding component, the first clamping fixture 31 and the second clamping fixture 32 are used to clamp and fix the printed circuit board 2000, the head of the thrust gauge 50 is arranged toward the coarse adjustment positioning device 100, specifically toward the side position where the electronic components to be tested on the printed circuit board 2000 are located, the aforementioned X-direction and Y-direction are two directions perpendicular to each other in the horizontal direction, specifically as Figure 3The X and Y directions are shown.

Figure 5 As shown in the three-axis directions of the mutually perpendicular horizontal X-direction, Y-direction and vertical Z-direction, the X-axis displacement fine-tuning device 201, the Y-axis displacement fine-tuning device 202 and the Z-axis displacement fine-tuning device 203 specifically adjust the alignment position of the electronic components soldered on the printed circuit board 2000 to be thrust tested and the head of the thrust gauge 50 with high precision and fineness from the three-axis directions of the mutually perpendicular horizontal X-direction, Y-direction and vertical Z-direction, so that the head of the thrust gauge 50 (specifically, the thrust head 51) is aligned with the middle position of the surface of the electronic component to be tested.

[0085] Compared with the prior art, the thrust testing device 1000 provided in the embodiment of the present application can first fix and preliminarily adjust the position of the fixed printed circuit board 2000 through the coarse adjustment positioning device 100, so as to preliminarily and roughly align the head of the thrust gauge 50 (specifically, it can be the thrust head 51) with the position of the electronic components on the printed circuit board 2000 that specifically need to be tested for the welding firmness. First, a quick and rough alignment is performed, specifically, the X-direction position of the printed circuit board 2000 is fixed and preliminarily slidably adjusted through the X-direction sliding component of the coarse adjustment positioning device 100 arranged on the upper surface of the fixed plate 10 and the first clamping fixing member 31 slidably connected to the X-direction sliding component, and the Y-direction position of the printed circuit board 2000 is fixed and preliminarily slidably adjusted through the Y-direction sliding component arranged on the upper surface of the fixed plate 10 and the second clamping fixing member 32 connected to the Y-direction sliding component; and then the Y-direction position of the printed circuit board 2000 is fixed and preliminarily slidably adjusted through the Y-direction sliding component connected to the front The fine adjustment positioning device 200 of the fixing plate 10 of the coarse adjustment positioning device 100 further finely adjusts the position of the head of the thrust gauge 50 (specifically, the thrust head 51) and the electronic component on the printed circuit board 2000 that needs to be tested for welding firmness with high precision. Specifically, the X-axis displacement fine adjustment device 201, the Y-axis displacement fine adjustment device 202 and the Z-axis displacement fine adjustment device 203 of the three-axis fine adjustment assembly of the fine adjustment positioning device 200 can respectively adjust the alignment position of the electronic component welded on the printed circuit board 2000 to be tested for thrust with the head of the thrust gauge 50 in three directions perpendicular to each other, namely, the horizontal X-axis and the Y-axis and the vertical Z-axis, with high precision and precision, so that the head of the thrust gauge (specifically, the thrust head) is aligned with the middle position of the electronic component to be tested facing its surface, thereby improving the precise positioning; after alignment, the testing device 300 performs the thrust test.

And the position of the circuit board baffle 321 on the third Y-direction slide rail 23 can be adjusted to correspondingly clamp printed circuit boards 2000 of different Y-direction sizes. And after the Y-direction sliding position is determined, it can be fixed by a hand screw 40 to fix the position of the printed circuit board 2000.

Specifically, the opposite ends of the first slot strip 311 can be respectively fixedly connected to the first X-direction slider 211 of the aforementioned first X-direction slide rail 21 and the third X-direction slider 221 of the aforementioned second X-direction slide rail 22; the opposite ends of the second slot strip 312 can be respectively fixedly connected to the second X-direction slider 212 of the aforementioned first X-direction slide rail 21 and the fourth X-direction slider 222 of the aforementioned second X-direction slide rail 22, so as to drive the first slot strip 311 and the second slot strip 312 to slide along the X-direction; and after the X-direction sliding position is determined, it can be fixed by hand screws 40 to fix the position of the printed circuit board 2000.

[0093] like Figure 2As shown, a further embodiment is that the aforementioned X-direction sliding assembly may also include a first slider transfer slot 2111, a second slider transfer slot 2121, a third slider transfer slot 2211 and a fourth slider transfer slot 2221 which are respectively fixedly connected to the aforementioned first X-direction slider 211, the second X-direction slider 212, the third X-direction slider 221 and the fourth X-direction slider 222; the two ends of the aforementioned first slot strip 311 may be respectively fixedly connected to the first slider transfer slot 2111 and the third slider transfer slot 2211, and the two ends of the aforementioned second slot strip 312 may be respectively fixedly connected to the second slider transfer slot 2121 and the fourth slider transfer slot 2221, so as to further improve the connection stability.
