[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 3 As shown, it relates to a semi-finished PCB testing device, including a base 1 and multiple molds 12, a first guide rail 2 is fixed to one side of the upper surface of the base 1, a first slide 3 is slidably connected to the surface of the first guide rail 2, a vertical plate 4 is fixed to the upper surface of the first slide 3, a second guide rail 5 is fixed to the top of the vertical plate 4, a second slide 6 is slidably connected to the surface of the second guide rail 5, a test assembly is fixed to the upper surface of the second slide 6, a positioning groove 11 for installing the mold 12 is opened on the side of the upper surface of the base 1 away from the first guide rail 2, each mold 12 is opened on the top of the placement groove 13 of different sizes, and a support assembly 14 is arranged inside the placement groove 13.

[0023] The first guide rail 2 and the second guide rail 5 are both T-shaped in cross section, and end plates are fixed at both ends of the first guide rail 2 and the second guide rail 5 .

[0024] Therefore, the first slide 3 will not be disengaged when sliding on the surface of the first guide rail 2 and the second slide 6 will not be disengaged when sliding on the surface of the second guide rail 5 .

[0025] The test assembly includes a horizontal plate 7 fixed to the upper surface of the second slide 6, a cylinder 8 and a detector 10 are fixed to the upper surface of the horizontal plate 7 away from the second slide 6, and a probe 9 connected to the detector 10 is fixed to the telescopic end at the bottom of the cylinder 8.

[0026] The cylinder 8 drives the probe 9 to descend and contact the contact points on the semi-finished PCB, so that the semi-finished PCB and the detector 10 can be connected.

[0027] A first locking bolt 31 passes through the top of the first sliding seat 3 and is threadedly connected. A second locking bolt 61 passes through the top of the second sliding seat 6 and is threadedly connected.

[0028] Moving the first slide 3 along the first guide rail 2 can adjust the position of the vertical plate 4 and the test assembly, and moving the second slide 6 along the second guide rail 5 can further adjust the position of the test assembly so that the probe 9 of the test assembly can be aligned with the contact of the semi-finished PCB.

[0029] An electromagnet 15 is fixed to the inner bottom wall of the positioning groove 11 , and an iron block 16 matching the electromagnet 15 is fixed to the lower surface of each mold 12 .

[0030] When the mold 12 is placed inside the positioning groove 11 , the electromagnet 15 is energized, and the electromagnet 15 attracts the iron block 16 to fix the mold 12 inside the positioning groove 11 .

[0031] The support assembly 14 includes a support plate 141 located inside the placement groove 13 and a plurality of grooves 142 opened on the bottom wall of the placement groove 13 . A spring 143 is fixed to the bottom wall of the groove 142 , and the top of the spring 143 is fixedly connected to the lower surface of the support plate 141 .

[0032] When the semi-finished PCB is placed inside the placement groove 13, the semi-finished PCB can be placed on the surface of the support plate 141. After the probe 9 is pressed down on the contact of the semi-finished PCB, the semi-finished PCB is pressed down into the placement groove 13. After the test is completed, the probe 9 rises, and the spring 143 rebounds upward and resets to lift the support plate 141, so that the semi-finished PCB is lifted out of the placement groove 13, making it easy to take the semi-finished PCB.

[0033] Working principle: First, select the corresponding mold 12 according to the size of the semi-finished PCB to be tested and put it into the positioning groove 11, then energize the electromagnet 15, and use the electromagnet 15 to absorb the iron block 16 at the bottom of the mold 12 to fix the mold 12, then move the first slide 3 and the second slide 6 to adjust the position of the probe 9, so that the probe 9 can align with the contact of the semi-finished PCB on the top of the mold 12, and then tighten the first locking bolt 31 and the second locking bolt 61 to fix the first slide 3 and the second slide 6 to fix the position of the probe 9. During the test, put the semi-finished PCB into the placement groove 13 on the top of the mold 12, and then start the cylinder 8 to drive the probe 9 to descend and contact with the contact of the semi-finished PCB. At this time, the semi-finished PCB can be tested by the detector 10. After the test, the cylinder 8 drives the probe 9 to rise and reset, and then the semi-finished PCB is taken away and replaced with the next semi-finished PCB. Therefore, when testing the same type of semi-finished PCB, it only needs to be positioned once, thereby improving the test efficiency.
