[0029] like Figure 1 and Figure 2 As shown, this utility model provides an integrated circuit test carrier board, including a base 10; and also includes:
[0030] The support assembly 20 includes a support frame 21 disposed at one end of the base 10, and a lifting cylinder 22 disposed at one end of the support frame 21 away from the base 10; the lifting direction of the lifting cylinder 22 is perpendicular to the base 10, and a test plate 221 is provided at one end of the lifting cylinder 22 near the base 10.
[0031] The test assembly 30 includes a test platform 31 disposed on the side of the base 10 near the lifting cylinder 22 and rotatably connected to the base 10, and a first fixing component 32 and a second fixing component 33 disposed on the side of the test platform 31 near the lifting cylinder 22; the first fixing component 32 and the second fixing component 33 are symmetrically arranged, and the first fixing component 32 and the second fixing component 33 are provided with airbag cushions 34 for placing the circuit board 40 under test.
[0032] In this embodiment, the integrated circuit test carrier uses the test stage 31 and the airbag 34 to place the circuit board under test 40 on the non-working airbag. The circuit board under test is then fixed to the test stage by a fixing component. By rotating the test stage, the airbag with the circuit board under test is rotated 180° to the test stage, completing the loading. A lifting cylinder moves the test stage downward, compressing the circuit board under test, which quickly and accurately verifies the performance and reliability of the circuit board under test. The airbag absorbs energy under impact force through compression and deformation, providing buffer protection for the circuit board under test. The intelligent pressure adjustment improves the stability of the test and the safety of the circuit board. Simultaneously, the circuit board under test is loaded and unloaded on another non-working airbag, improving the degree of automation. The loading and unloading is convenient and quick, the operation is simple, and continuous testing is possible, improving testing efficiency. In addition, this integrated circuit test carrier is suitable for circuit boards of different specifications and sizes, facilitating precise clamping.
[0033] In some implementations, such as Figure 3 As shown, the base 10 is provided with a slide rail 11, and a slide bar 12 is provided on the slide rail 11 and slidably connected to the slide rail 11. A rack 13 is provided on the side of the slide bar 12. A gear 311 is provided on the side of the test platform 31 near the base 10, and the gear 311 meshes with the rack 13. By using the linear movement of the slide bar 12 along the slide rail 11, the rack 13 is driven to move linearly, thereby causing the gear 311 to move in a circular motion relative to the rack 13, so that the test platform 31 can rotate relative to the base 10.
[0034] Specifically, the test platform 31 is rotatably connected to the base 10 via the gear 311, allowing the test platform 31 to rotate relative to the base 10. By controlling the linear motion of the slider 12 relative to the slide rail 11, the rack 13 drives the gear 311 to perform circular motion, thereby achieving the rotation of the test platform.
[0035] In some embodiments, the base 10 is provided with a push cylinder 14, the output end of which is fixedly connected to one end of the sliding bar 12. Using the push cylinder 14, the sliding bar 12 can reciprocate along the slide rail 11.
[0036] In a preferred embodiment, the push cylinder 14 is electrically connected to the controller 50, and the controller 50 controls the operation of the push cylinder 14.
[0037] In some embodiments, the support frame 21 is equipped with a controller 50, which is electrically connected to the lifting cylinder 22. The controller 50 can control the lifting movement of the lifting cylinder 22, thereby driving the movement of the test board 221 to achieve the testing of the circuit board under test.
[0038] In some embodiments, the test board 221 is matched with the circuit board under test 40. The air cushion 34 provides buffer protection for the circuit board under test 40, and the test board 221 compresses the circuit board under test 40 to achieve the testing of the circuit board under test 40.
[0039] In some implementations, such as Figure 1 and Figure 4 As shown, both the first fixing component 32 and the second fixing component 33 include: a mounting plate 321 symmetrically arranged on the edge of the test platform 31, and a clamping plate 322 disposed on one side of the mounting plate 321; the airbag cushion 34 is disposed between the symmetrically arranged mounting plates 321; the clamping plate 322 is disposed on the side of the mounting plate 321 near the airbag cushion 34. Using the symmetrically arranged mounting plates 321 and clamping plates 322, the circuit board to be tested placed above the airbag cushion 34 can be clamped, ensuring uniform force on the circuit board. Furthermore, this integrated circuit test carrier is suitable for circuit boards of different specifications and sizes, and facilitates precise clamping.
[0040] Specifically, in use, the circuit board to be tested is placed on the airbag pad on the side away from the support frame 21. Two opposing clamping plates move towards the circuit board to stably clamp and fix it on the test stage 31. This structure is suitable for circuit boards of different specifications and sizes, facilitating precise clamping. The test stage is rotated 180° by gears to complete the loading. The lifting cylinder moves the test plate downwards, squeezing the circuit board to achieve rapid and accurate verification of the circuit board's performance and reliability. The airbag pad absorbs energy under impact force compression and deformation, providing buffer protection for the circuit board to be tested. It achieves intelligent pressure adjustment, improving the stability of the test and the safety of the circuit board to be tested. While the circuit board to be tested is being tested, another airbag pad is used to load and unload the circuit board to be tested. The system is highly automated, with convenient and quick loading and unloading, simple operation, and continuous testing capability, thus improving testing efficiency.
[0041] In some embodiments, the mounting plate 321 is provided with a threaded hole; a threaded knob 323 passes through the threaded hole and is rotatably connected to the clamping plate 322. By rotating the threaded knob 323 through the threaded hole, relative movement of the clamping plate 322 can be achieved, thereby realizing the clamping and releasing of the circuit board to be tested.
[0042] In some embodiments, at least one spring member 324 is provided between the mounting plate 321 and the clamping plate 322; the clamping plate 322 has an anti-slip rubber pad 325 on the side opposite to the mounting plate 321. The spring member 324 provides a buffer force for the clamping plate 322, while also reducing the rotational force on the knob member 323; while the anti-slip rubber pad 325 prevents the circuit board under test from loosening during testing, providing a better clamping effect.
[0043] In some embodiments, a spring 324 is provided between the mounting plate 321 and the clamping plate 322. The spring is sleeved on the knob 323 to ensure that the clamping plate can move horizontally, and the anti-slip rubber pad can increase friction and better fix the circuit board to be tested.
[0044] In some implementations, such as Figure 5 As shown, the base 10 is provided with an air pump 60 on the side near the test platform 31; the air pump 60 is connected to an air inlet pipe 61, and the end of the air inlet pipe 61 away from the air pump 60 passes through the test platform 31 and connects to the side of the airbag pad 34 near the test platform 31.
[0045] Specifically, the air pump 60 is electrically connected to the controller 50. By adjusting the gas pressure inside the airbag 34, the air pump indirectly adjusts the downward pressure of the test board 221 on the circuit board under test, providing buffer protection.
[0046] In some embodiments, the support frame 21 includes a full side plate 211, two half side plates 212, and a top plate 213; the full side plate 211 is fixedly connected to one end of the base 10, and the top plate 213 is fixedly connected to the end of the full side plate 211 opposite to the base 10 via the two half side plates 212; the lifting cylinder 22 is disposed on the side of the top plate 213 near the base 10. This structure of the support frame 21 has high strength, sufficient to support the interaction force generated when the lifting cylinder 22 presses against the circuit board under test.

This utility model's integrated circuit test carrier utilizes a test bench and an airbag pad. The circuit board under test (PCB) is placed on the airbag pad in its non-operating state, and then fixed to the test bench by a fixing component. Rotating the test bench causes the airbag pad holding the PCB to rotate 180° under the test board, completing the loading process. A lifting cylinder moves the test board downwards, compressing the PCB and quickly and accurately verifying its performance and reliability. The airbag pad absorbs energy under impact force, providing cushioning protection for the PCB. Intelligent pressure adjustment improves test stability and PCB safety. Simultaneously, PCBs are loaded and unloaded on another non-operating airbag pad, increasing automation. Loading and unloading are convenient and quick, operation is simple, and continuous testing is possible, improving testing efficiency. Furthermore, this integrated circuit test carrier is suitable for circuit boards of different specifications and sizes, facilitating precise clamping.
