[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides, for example Figure 1-4 As shown:

[0036] Example 1,

[0037] A motherboard FCT testing device includes: a workbench 1, a fixing mechanism for fixing the motherboard is provided on the surface of the workbench 1, and a pressure groove is formed on the surface of the workbench 1.

[0038] The testing mechanism is used to perform FCT testing on the motherboard. The testing mechanism includes a testing section and a driving section, and the output ends of the testing section and the driving section are connected by a transmission.

[0039] Specifically, the testing department includes:

[0040] Support frame 2 is fixedly installed on the surface of workbench 1, and limit grooves are provided on both inner walls of the support frame 2.

[0041] The limiting post 6 is fixedly installed on the surface of the workbench 1, and the end of the limiting post 6 away from the workbench 1 is fixedly connected to the support frame 2.

[0042] Limiting block 7 is slidably installed in the limiting groove;

[0043] Pressure plate 5 is slidably installed in support frame 2. The side of pressure plate 5 is fixedly connected to limit block 7. A sliding groove is provided on the side of pressure plate 5 near workbench 1. The sliding groove is slidably connected to limit post 6.

[0044] Pressure pins 16, multiple pressure pins 16 are evenly arranged at the bottom of pressure plate 5, and pressure pins 16 are used to test the motherboard;

[0045] It should be noted that a pressure groove is provided on the upper surface of the workbench 1. The support mechanism is located in the pressure groove and is slidably connected to the inner wall of the pressure groove. The testing mechanism is welded to the upper surface of the workbench 1. The testing part is located above the pressure groove and is parallel to the pressure groove. The driving part is installed on the side of the support mechanism near the pressure groove and above the testing part. The motherboard is placed on the support mechanism, and the driving part is started. The driving part drives the pressure plate 5 to move downward. The movement of the pressure plate 5 causes the pressure needle 16 to move to the surface of the motherboard. The motherboard is tested by the pressure needle 16. The movement of the pressure plate 5 is restricted by the cooperation of the limiting post 6 and the limiting block 7 to avoid the pressure plate 5 from moving off course during the test, which would cause a decrease in measurement accuracy.

[0046] Specifically, the drive unit includes:

[0047] Hydraulic press 3 is mounted on the surface of support frame 2 and is used to push pressure plate 5 to move.

[0048] Hydraulic rod 4 is fixedly connected to the output end of hydraulic press 3, and hydraulic rod 4 is fixedly connected to pressure plate 5;

[0049] It should be noted that the hydraulic press 3 is installed on the side of the support frame 2 near the pressure groove. The output end of the hydraulic press 3 is located above the test section, and the hydraulic rod 4 is located between the output end of the hydraulic press 3 and the test section. During the testing of the motherboard, the hydraulic press 3 is started, and the hydraulic rod 4 is pushed through the output end of the hydraulic press 3. The movement of the hydraulic rod 4 drives the test section to move, and the motherboard is tested through the movement of the test section.

[0050] The side wall of the workbench 1 is provided with multiple ventilation holes 15, which are used for heat dissipation inside the workbench 1.

[0051] It should be noted that the ventilation holes 15 can dissipate heat from the inside of the workbench 1, preventing the internal temperature of the workbench 1 from overheating during the test, making the device safer to use and extending its lifespan.

[0052] Example 2: This utility model provides a fixing mechanism, applied to a motherboard FCT testing device for a chemical raw material as described in Example 1. The fixing mechanism includes:

[0053] Limiting strips 8, multiple limiting strips 8 are symmetrically arranged on the surface of the worktable 1, and the limiting strips 8 are provided with moving grooves;

[0054] The threaded rod 10 is rotatably inserted into the movable groove. The thread of the threaded rod 10 is bidirectional, and the threaded rod 10 is threadedly sleeved with the fixed block 11.

[0055] Twist block 9 is disposed at one end of threaded rod 10 and located on the side of limit bar 8;

[0056] The fixing block 11 is slidably connected to the moving groove and is used to fix the motherboard.

[0057] It should be noted that the limit bar 8 is installed on the upper surface of the workbench 1 and located on both sides of the pressure groove. The torsion block 9 is slidably installed on the side of the limit bar 8 away from the support frame 2. The fixing block 11 is slidably installed in the moving groove. When the motherboard is placed on the support mechanism, the torsion block 9 is rotated to drive the threaded rod 10 to rotate. Since the threads at the left and right ends of the threaded rod 10 are opposite, the fixing blocks 11 are driven to move closer to each other, so that the fixing blocks 11 move to the surface of the test motherboard. The test motherboard is fixed by the fixing blocks 11 to prevent the test motherboard from shifting during the test. At the same time, the restriction of the fixing blocks 11 can effectively prevent the motherboard from shifting or popping out during the reset process, thereby reducing the scrap rate of the motherboard FCT test.

[0058] Mainboard carrier 12 is slidably mounted in the pressure groove;

[0059] The elastic column 13 is fixedly installed at the bottom of the pressure groove, and the end of the elastic column 13 away from the bottom of the pressure groove is fixedly connected to the main board carrier 12.

[0060] A limiting element is installed inside the pressure groove to limit the displacement of the mainboard carrier 12;

[0061] It should be noted that the motherboard carrier 12 is located below the pressure plate 5 and is parallel to the pressure plate 5. The elastic column 13 is installed at the bottom of the pressure groove. The end of the elastic column 13 away from the bottom of the pressure groove is fixedly connected to the side of the motherboard carrier 12 away from the pressure plate 5. When the motherboard is placed on the surface of the motherboard carrier 12, during the test, when the test part contacts and presses down on the surface of the motherboard, the elastic column 13 is pressed down, causing the motherboard carrier 12 to move down. When the test is completed, the test part moves up, the elastic column 13 is pressed down and reset, causing the motherboard carrier 12 to move up.

[0062] Specifically, the limiting component includes a limiting plate 14, which is fixedly installed in the pressure groove and is used to limit the movement of the main board carrier 12.

[0063] It should be noted that the limiting plate 14 is installed below the motherboard carrier 12. When the motherboard carrier 12 moves down and touches the limiting plate 14, pressure is generated. A pressure sensor can be installed on the limiting plate 14 so that the pressure signal of the limiting plate 14 is transmitted to the control center. The control center stops the start of the test section, so that the pressure between the test section and the motherboard is smaller, reducing the possibility of damage to the components on the motherboard.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
