[0051] According to the testing device 100 of the embodiment of the present invention, the device under test 200 can be located within the vacuum chamber 10 for testing.

[0052] In some embodiments of the present invention, reference Figure 2 and Figure 3 The vacuum chamber 10 may include: a shell 11, a first cover plate 12, a first seal 13, a second cover plate 14 and a second seal 15. The shell 11 is open at both ends in the axial direction and forms a first opening 11a and a second opening 11b; the first cover plate 12 is detachably covered on the first opening 11a; the first seal 13 is arranged between the first cover plate 12 and the shell 11; the second cover plate 14 is detachably covered on the second opening 11b; the second seal 15 is arranged between the second cover plate 14 and the shell 11.

[0057] In the above technical solution, the first opening 11a and the second opening 11b at both ends of the housing 11 are equipped with removable first and second cover plates 12, 14, enabling rapid installation, commissioning, or replacement of internal components. First and second seals 13, 15 are respectively disposed at both ends of the housing 11. By compressing and deforming, they fill the gap between the contact surfaces, improving the sealing performance of the first and second cover plates 12, 14 and ensuring the reliability of the vacuum chamber 10.

[0058] In some embodiments of the present invention, reference Figure 1 and Figure 3The heating component 20 and the circuit testing component 30 are disposed on the first cover plate 12. In the above technical solution, the heating component 20 and the circuit testing component 30 are co-located on the first cover plate 12 and can be removed along with the first cover plate 12, facilitating replacement and maintenance. Furthermore, the heating component 20 and the circuit testing component 30 are located outside the vacuum chamber 10, which reduces the volume of the vacuum chamber 10, conserving materials, and lowering costs.

[0059] In some embodiments of the present invention, reference Figures 1 to 3 The vacuum pumping component 40 and the vacuum measuring component 50 are installed on the second cover plate 14. In the above technical solution, the vacuum pumping component 40 and the vacuum measuring component 50 can be installed on the second cover plate 14 to perform vacuum pumping and vacuum level testing operations on the vacuum chamber 10. At the same time, the vacuum pumping component 40 and the vacuum measuring component 50 are centrally installed on the second cover plate 14, forming an independent "vacuum control module" for easy operation and replacement.

[0060] In some embodiments of the present invention, reference Figures 1 to 3 The vacuum pumping component 40 may include a first pipe 41, a second pipe 42 and a first one-way conducting member 43. The first pipe 41 and the second pipe 42 are connected by the first one-way conducting member 43, and the second pipe 42 is disposed in the vacuum chamber 10. The vacuum measuring component 50 includes a third pipe 51, a fourth pipe 52 and a second one-way conducting member 53. The third pipe 51 and the fourth pipe 52 are connected by the second one-way conducting member 53, and the fourth pipe 52 is disposed in the vacuum chamber 10.

[0061] The first pipe 41 may be a pipe connected to a vacuum pump, and optionally, the first pipe 41 may be a KF vacuum joint. The third pipe 51 may be a mechanism connected to a vacuum measuring device, and optionally, the third pipe 51 may be a KF vacuum joint.

[0062] The first and second one-way conducting members 43 and 53 may be mechanisms or components that control the one-way flow of gas. For example, the first and second one-way conducting members 43 and 53 may be switches electrically controlled to achieve one-way flow, or switches that inherently provide one-way flow. Optionally, the first and second one-way conducting members 43 and 53 may be one-way valves.

[0063] In the above technical solution, the first pipe 41 is directly connected to the external vacuum pump (vacuum pump assembly), and the second pipe 42 is installed in the vacuum chamber 10 and close to the inner wall, forming a short-path, low-resistance exhaust channel, thereby improving exhaust efficiency. The first one-way guide 43 automatically blocks the airflow after the vacuum pump stops, preventing the external atmosphere from flowing back into the vacuum chamber 10, ensuring the reliability of the vacuum environment during testing. The fourth pipe 52 is installed in the vacuum chamber 10 to directly collect the vacuum level inside the vacuum chamber 10, avoiding measurement delays caused by long pipeline transmission. The second one-way guide 53 can prevent external gas from entering the vacuum chamber 10 when measuring the vacuum level, preventing the vacuum environment inside the vacuum chamber 10 from being disrupted by human operation, thereby improving the reliability of the vacuum chamber 10 and further improving the reliability of the testing device 100.

[0064] In some embodiments of the present invention, reference Figure 3 and Figure 8 The vacuum chamber 10 is cylindrical, the first direction is parallel to the axial direction of the vacuum chamber 10 , and the vibration component 60 includes a rolling element 66 . The rolling element 66 is provided on opposite sides of the first platform 63 and abuts against the inner wall of the vacuum chamber 10 .

[0065] For ease of understanding, the “axial direction” can be referred to Figure 1 left and right directions.

[0066] The rolling element 66 may refer to a structural element that can roll on the inner wall of the vacuum chamber 10. The number of the rolling elements 66 may be, but is not limited to, two, three, four, five, six, etc. The rolling element 66 may be, but is not limited to, a roller, a roller shaft, etc. Optionally, the rolling element 66 is a roller.

[0067] In the above technical solution, the inner wall of the cylindrical vacuum chamber 10 is a continuous arc surface, and the rolling elements 66 on both sides of the first platform 63 form symmetrical abutment with the inner wall, thereby evenly distributing the centrifugal force generated by the rotational motion to the inner wall of the vacuum chamber 10, thereby preventing the first platform 63 from tilting or getting stuck due to uneven force, improving the stability of the first platform 63 in rotational vibration around the first direction, and thereby improving the reliability of the testing device 100.

[0068] In some embodiments of the present invention, reference Figure 4 and Figure 6 The vibrating member 64 may include: a motor 641, a driving wheel 642, a driven wheel 643 and a cam 644, the motor 641 is arranged on the first platform 63; the driving wheel 642 is connected to the motor shaft 6411 of the motor 641; the driven wheel 643 is pivotally arranged on the first platform 63 and meshes with the driving wheel 642; the cam 644 is connected to the driven wheel 643, and drives the second platform 65 to reciprocate along the second direction.

[0069] In the above technical solution, the motor 641 drives the driving wheel 642 to rotate, and the driving wheel 642 drives the cam 644 to move via the driven wheel 643. Due to the eccentric structural design of the cam 644, the cam 644 can drive the second platform 65 to reciprocate in the second direction during the rotation process, thereby achieving the vibration of the second platform 65 relative to the first platform 63. It can be understood that the structure of the vibration member 64 including the motor 641, the driving wheel 642, the driven wheel 643 and the cam 644 has a simple structure, can improve the stability of the vibration member 64, and further improve the reliability of the testing device 100.

[0070] In some embodiments of the present invention, reference Figure 6 and Figure 7 An avoidance groove 63 a is provided on the first platform 63 near the driven wheel 643 and the cam 644 .

[0071] The area of ​​the avoidance groove 63 a on the first platform 63 may cover the projected areas of the driven wheel 643 and the cam 644 on the first platform 63 , and the avoidance groove 63 a may penetrate the first platform 63 .

[0072] In the above technical solution, an avoidance groove 63a is provided on the first platform 63 near the driven wheel 643 and the cam 644, so that the driven wheel 643 and the cam 644 can be partially located in the avoidance groove 63a, which can reduce the height of the driven wheel 643 and the cam 644 in the direction from the first platform 63 to the second platform 65, making the structure of the vibration component 60 more compact, reducing the volume of the vibration component 60, and further reducing the volume of the vacuum chamber 10, which is convenient for transportation and installation, and can also save materials and reduce costs.

[0073] In some embodiments of the present invention, reference Figure 6 and Figure 7 The cam 644 is provided with a guide groove 644a, which extends along the circumferential edge contour of the cam 644. A push rod 651 is provided on the side of the second platform 65 close to the first platform 63. The push rod 651 is provided with a first roller 6511. The first roller 6511 is arranged in the guide groove 644a and abuts against the bottom groove wall 6441 of the guide groove 644a.

[0074] In the above technical solution, the guide groove 644a extends along the circumferential edge profile of the cam 644. After the first roller 6511 of the push rod 651 is embedded in the guide groove 644a, its motion trajectory is completely determined by the profile of the cam 644, which has a guiding effect and can ensure the accuracy of the vibration trajectory. The bottom groove wall 6441 of the guide groove 644a abuts, and the two side walls of the guide groove 644a form a lateral limit for the roller, preventing the push rod 651 from axially deviating during the vibration process, thereby ensuring the stability of the vibration trajectory. Secondly, the push rod 651 achieves rolling contact with the guide groove 644a through the first roller 6511, which can reduce the wear of the push rod 651 and the cam 644, improve the long-term stability of the vibration, and extend the service life of the entire vibrating member 64. The use of rolling friction also helps to reduce the waste generated by wear and tear from contaminating the test piece 200.

[0075] In some embodiments of the present invention, reference Figure 6 and Figure 7 Second rollers 6512 are provided at both ends of the push rod 651 in the axial direction of the cam 644 , and the second rollers 6512 abut against the surface of the cam 644 .

[0076] It is understandable that both ends of the second roller 6512 can contact the inner and outer ends of the cam 644 .

[0077] In the above technical solution, the second roller 6512 abuts against the surface of the cam 644, and the movement trajectories of the second roller 6512 and the first roller 6511 are similar. This can increase the supporting surface between the cam 644 and the push rod 651, improve the supporting stability of the cam 644 on the push rod 651, and further improve the stability of the second platform 65 relative to the first platform 63 during the vibration process, which can improve the stability of the vibration trajectory and further improve the reliability of the vibration.

[0078] In some embodiments of the present invention, reference Figures 4 to 7 The first platform 63 is provided with a limiting assembly 631, which is arranged on the first platform 63 at opposite sides of the vibrating member 64; the limiting assembly 631 includes a limiting rod 6311 and a shock-absorbing component 6312, the limiting rod 6311 is arranged on the first platform 63, and slides with the second platform 65 along the second direction, and the shock-absorbing component 6312 is sleeved on the limiting rod 6311 and abuts against the first platform 63 and the second platform 65.

[0079] The limiting rod 6311 may refer to a mechanism that limits the distance between the second platform 65 and the first platform 63 , and may be, but not limited to, a cylindrical straight rod, a stepped shaft, a spline shaft, an air-floating shaft, and the like.

[0080] The shock absorbing component 6312 may refer to a mechanism capable of shock absorption, and may be, but not limited to, an elastic element, a damper, a composite structure, etc. For example, the elastic element may be, but not limited to, a spring, a rubber pad or a rubber spring, a polyurethane shock absorber, etc.

[0081] In the above technical solution, the limiting rod 6311 slides with the second platform 65 along the second direction, providing a rigid guide path for it, limiting the displacement of the second platform 65 in the non-vibration direction, ensuring that the vibrating member 64 moves only in the predetermined direction, avoiding the vibration component 60 from being stuck or the test error caused by the offset, and improving the reliability of the vibration. At the same time, the limiting assembly 631 is arranged on the first platform 63 on opposite sides of the vibrating member 64, forming a symmetrical constraint structure, balancing the lateral force during the vibration process, avoiding the second platform 65 from tilting or twisting, and improving the smoothness of the movement of the vibrating member 64. The shock-absorbing component 6312 can undergo elastic deformation when the second platform 65 vibrates, converting the vibration energy into heat energy or elastic potential energy, thereby playing a buffering role, which is conducive to reducing the impact force between the top rod 651 and the cam 644, and can improve the reliability of the test device 100.
