[0026] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited are not intended to limit the present utility model.

[0027] Since a pressure bar is connected to the main board to be tested, interference occurs due to the presence of the pressure bar during the process of pressing the CPU into the main board to be tested, and when the main board to be tested is placed on the test device, the position and angle cannot be guaranteed to be consistent. Therefore, both aspects need to be adjusted.

[0028] Refer to Figure 1 、 2 As shown, the main board testing device of the present utility model includes: a test frame body 1, a lifting drive assembly 2, a main board angle adjustment assembly 4, a pressure bar detection assembly 5, a CPU 100, a main board 200 to be tested, and a pressure bar 300 as several main parts; the test frame body 1 serves as the overall support part of the main board testing device; the lifting drive assembly 2 is arranged on the test frame body 1, a CPU fixing block 3 is connected to the lifting drive assembly 2, a CPU for testing is provided on the CPU fixing block 3, and the lifting drive assembly 2 drives the CPU to contact the main board to be tested for testing; the main board angle adjustment assembly 4 is arranged on the test frame body 1, and the main board angle adjustment assembly 4 is used to adjust the main board to be tested to the test angle; the pressure bar detection assembly 5 is arranged on the test frame body 1, and the pressure bar detection assembly 5 is used to test the angle of the pressure bar of the main board to be tested to avoid interference during testing.

[0029] Refer to Figure 3As shown, the main board angle adjustment component 4 includes an adjustment drive motor 41, a motor clamping plate 42, a rotating disk 43, and a lever 44. The adjustment drive motor 41 is fixed to the test frame 1 through the motor clamping plate 42. The rotating disk 43 is connected to the rotating shaft of the adjustment drive motor 41. One end of the lever 44 is fixedly connected to the rotating disk 43, and the other end of the lever 44 can contact the main board to be tested. When the rotating shaft of the adjustment drive motor 41 rotates, it can drive the rotating disk 43 to rotate, and then drive the lever 44 to rotate, so that the other end of the lever 44 contacts the main board to be tested during rotation and pushes the main board to be tested to the test angle, that is, the test surface of the main board to be tested is set opposite to the CPU. A first induction strip 431 and a second induction strip 432 are connected to the rotating disk 43. A first U-shaped photoelectric switch 11 and a second U-shaped photoelectric switch 12 are installed on the test frame 1. The first U-shaped photoelectric switch 11 is used to sense the position information of the first induction strip 431, and the second U-shaped photoelectric switch 12 is used to sense the position information of the second induction strip 432. One ends of the first induction strip 431 and the second induction strip 432 are fixedly arranged on the rotating disk 43, and the other ends of the first induction strip 431 and the second induction strip 432 extend out of the outer circumference of the rotating disk 43.

[0030] Refer to Figure 4 , 5 As shown, the pressure bar detection component 5 includes a T-shaped bracket 51, a first guide post 52, a floating spring, a microswitch 53, a switch mounting block 54, and a connecting rod 55.

The driving rod of the micro switch 53 penetrates through the first inclined surface 541, and the second inclined surface 542 is used to straighten the pressing rod of the motherboard to be tested that is not interfered. The micro switch 53 is provided on the first inclined surface 541. When the pressing rod of the motherboard to be tested is at a small angle between 35° and 90°, at this time, the pressing rod of the motherboard to be tested is in the interference position of the test. Once the micro switch 53 detects the pressing rod of the motherboard to be tested, it will give an error reminder to remind the staff to adjust; when the pressing rod of the motherboard to be tested is on the side in contact with the second inclined surface 542, at this time, as the motherboard to be tested approaches the CPU, the slope of the second inclined surface 542 pushes the pressing rod of the motherboard to be tested to continuously rotate towards the non-interfering side until it reaches the specified position. The pressing rod of the motherboard to be tested has a position of a rotating support shaft on the motherboard to be tested. The intersection line between the first inclined surface 541 and the second inclined surface 542 is not on the same straight line as the axis of the rotating support shaft, which can avoid the pressing rod of the motherboard to be tested being stuck at the corner position between the first inclined surface 541 and the second inclined surface 542.

[0032] Refer to Figure 6 , 7 As shown, the lifting drive assembly 2 includes a lead screw motor 21 and a lifting plate 22. The lead screw motor 21 is fixedly arranged on the test frame 1.

A position sensing strip 222 is connected to the lifting plate 22. The test frame 1 is provided with a third U-shaped photoelectric switch 14 and a fourth U-shaped photoelectric switch 15. The third U-shaped photoelectric switch 14 and the fourth U-shaped photoelectric switch 15 are used to sense the position information of the position sensing strip 222 to judge the position of the lifting plate 22.

[0033] In the above structure, a sliding guide post 221 is connected to the lifting plate 22. The test frame 1 is provided with a fixed bottom plate 13. A guide sliding sleeve 131 is provided on the fixed bottom plate 13. The sliding guide post 221 penetrates through the guide sliding sleeve 131, and the sliding guide post 221 is slidably connected to the guide sliding sleeve 131.

[0034] In the above structure, the lower end of the sliding guide post 221 penetrating through the guide sliding sleeve 131 is connected with an adapter plate 23. The adapter plate 23 is connected with a heat dissipation copper block 24. The CPU fixing block 3 is connected to the heat dissipation copper block 24. A heat dissipation fan 25 is connected to the adapter plate 23. The heat dissipation copper block 24 and the heat dissipation fan 25 cooperate to dissipate heat from the CPU.

[0035] In addition, a buffer assembly 26 is provided between the adapter board 23 and the heat dissipation copper block 24 connected to the adapter board 23. The buffer assembly 26 includes equal-height screws 261 and buffer springs 262. The upper end of the equal-height screw 261 is disposed on the adapter board 23, and the lower end of the equal-height screw 261 is fixedly connected to the heat dissipation copper block 24. The buffer spring 262 is sleeved on the equal-height screw 261, and the buffer spring 262 is located between the heat dissipation copper block 24 and the adapter board 23.

[0036] When the lead screw motor 21 drives the CPU 100 to descend and contact the main board 200 to be tested, once the pressing force is too large, the equal-height screw 261 will move upward, compressing the buffer spring 262, playing a buffering role to avoid damaging the main board 200 to be tested.

[0037] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
