Technical Field

[0001] This utility model relates to the technical field of electrostatic discharge testing devices, and in particular to an electrostatic discharge testing device. Background Technology

[0002] Electrostatic discharge (ESD) testing is a crucial step in verifying the reliability of electronic products. Current small-scale ESD testing typically relies on manual handheld ESD generators to discharge the device under test (DUT). This manual method has several technical drawbacks: precise discharge location and stable discharge angle are difficult to maintain when the ESD generator is held manually, affecting the accuracy and consistency of test results; continuous manual testing can lead to fatigue, impacting test quality. Fully automated ESD testing devices, on the other hand, are often prohibitively expensive.

[0003] Therefore, there is an urgent need to develop an electrostatic discharge testing device to solve the above problems. Utility Model Content

Detailed Implementation

[0022] Based on the teachings of this specification, those skilled in the art can form new technical solutions by combining different implementation methods without creating technical contradictions. Such variations should be considered to fall within the protection scope of this patent.

[0023] The electrostatic discharge testing device of the present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0024] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0025] like Figure 1 As shown in the figure, this utility model embodiment proposes a simple and practical electrostatic discharge testing device, including a base 1, a device shaft 2, a drive device, a clamping component 6, and an ESD generator 7.

[0026] Specifically, the device shaft 2 is mounted on the base 1; the drive device is mounted on the device shaft 2 and rotatably connected to the clamping member 6; the clamping member 6 is used to clamp and fix the ESD generator 7; the drive device is used to drive the ESD generator 7 to move up and down, left and right, and rotate at an angle. This structural design improves the automation level and testing accuracy of electrostatic discharge testing.

[0027] Preferably, the driving device includes a sliding assembly 3, a sleeve 4, and a telescopic rod 5.

[0028] Specifically, the sliding kit 3 is sleeved on the device shaft 2 and slidably connected to the side wall of the device shaft 2.

[0029] In one embodiment, the driving device further includes a fixing member 8. Specifically, the side wall of the sliding assembly 3 has a through hole; the fixing member 8 passes through the through hole and extends into the sliding assembly 3 to abut against the device shaft 2; the fixing member 8 is threadedly connected to the through hole. This structure improves the stability of the device.

[0030] In a specific example, the fastener 8 may be a bolt, and those skilled in the art will know that the specific size of the bolt can be set according to actual needs.

[0031] In actual use, you can hold the sliding kit 3 with one hand, rotate the fixing piece 8 with the other hand to loosen it, then adjust the sliding kit 3 to a suitable position and tighten the fixing piece 8.

[0032] Furthermore, the inner wall of the sliding assembly 3 is provided with a groove 12, and the outer wall of the device shaft 2 is provided with a slider 13 that mates with the groove. The fixing member 8 passes through the through hole and extends into the sliding assembly 3 to abut against the slider 13. This structure improves the smoothness of sliding and the positioning accuracy.

[0033] One end of the sleeve 4 is connected to the sliding assembly 3; the telescopic rod 5 is slidably disposed inside the sleeve 4, and one end extends outside the sleeve 4 and is rotatably connected to the clamping member 6. Thus, the telescopic rod 5 can extend or retract into the sliding assembly 3, thereby driving the clamping member 6 to move. This structure enhances the degree of freedom of movement of the ESD generator 7.

[0034] Preferably, an angle adjustment mechanism (not shown in the figure) is provided between the telescopic rod 5 and the clamping member 6. As an example, the angle adjustment mechanism includes a rotating shaft and a locking nut. One end of the rotating shaft is fixedly connected to the telescopic rod 5, and the other end is rotatably connected to the clamping member 6. The locking nut is used to fix the angle between the rotating shaft and the clamping member 6. This design enhances the flexibility and accuracy of angle adjustment. In another feasible embodiment, the angle adjustment mechanism can employ a damped rotating shaft, thereby enabling more convenient position adjustment.

[0035] In one embodiment, the clamping member 6 includes a clamping ring and a fastening bolt. Specifically, the clamping ring is used to surround the ESD generator 7, and the fastening bolt passes through both ends of the clamping ring and is locked by a nut. This structure improves the reliability of the ESD generator 7's fixation.

[0036] Preferably, the device axis 2 is perpendicular to the base 1, which increases the utilization rate of the workspace.

[0037] In this embodiment, the bottom of the base 1 is provided with an anti-slip pad (not shown in the figure). Specifically, the anti-slip pad can be made of rubber and has a thickness of 3-5mm. Those skilled in the art will know that the specific parameters of the anti-slip pad can be set according to actual needs, and other embodiments besides this one are also possible.

[0038] In a specific example, combined Figure 2 As shown, the driving device in this embodiment may further include a drive motor assembly. Specifically, the drive motor assembly includes a vertical drive motor 9, a horizontal drive motor 10, and an angle drive motor 11.

[0039] The up-and-down drive motor 9 can be a stepper motor, connected to the sliding assembly 3, and used to drive the sliding assembly 3 to move up and down on the device shaft 2. With the up-and-down drive motor 9, the design of the fixing member 8 can be omitted. As an example, the drive device includes the up-and-down drive motor 9 and a reciprocating lead screw 14; the up-and-down drive motor 9 is mounted on the base 1, and the output shaft is connected to the reciprocating lead screw 14. The end of the reciprocating lead screw 14 away from the up-and-down drive motor 9 passes through the sliding assembly 3 and is threadedly connected to the sliding assembly 3. Therefore, when the up-and-down drive motor 9 starts, it drives the reciprocating lead screw 14 to rotate. With the threaded connection, since the device shaft 2 is fixed on the base 1, the rotation of the reciprocating lead screw 14 can drive the sliding assembly to move up and down, thereby enabling the up-and-down movement of the ESD generator 7.

[0040] The left and right drive motors 10 can be servo motors, connected to the telescopic rod 5, and used to drive the telescopic rod 5 to perform telescopic movement. As an example, the left and right drive motors 10 are fixed on the sliding kit 3 and connected to the sleeve 4 and the telescopic rod 5 to form an electric telescopic rod (for example, the electric telescopic rod can adopt existing technology, such as an electric push rod of model LX835), thereby realizing the automatic extension and retraction of the telescopic rod 5 to drive the ESD generator 7 to move in the horizontal direction.

[0041] The angle drive motor 11 can be a precision stepper motor, connected to the angle adjustment mechanism, and used to drive the ESD generator 7 to adjust the angle. As an example, the angle drive motor 11 is fixed to the end of the telescopic rod 5 away from the sliding kit 3. The angle adjustment mechanism may include, for example, a rotating shaft (not shown in the figure), with a clamping member 6 fixedly connected to the surface of the rotating shaft. The output shaft of the angle drive motor 11 is connected to the end of the rotating shaft to drive the rotating shaft to rotate, thereby causing the clamping member 6 to rotate and achieve angle adjustment.

[0042] As will be known to those skilled in the art, the specific model and parameters of the motor can be set according to actual needs, and other embodiments besides this one are also included.

[0043] In one specific example, the control system may further include a position sensor (not shown in the figure) for real-time detection of the spatial position and angle information of the ESD generator 7, forming a closed-loop control and improving positioning accuracy. The position sensor may be a photoelectric encoder or a magnetic sensor, mounted on the corresponding moving parts.

[0044] In this embodiment, the working process of the electrostatic discharge testing device is as follows: First, the ESD generator 7 is fixed on the clamping member 6 by the clamping ring and fastening bolt; then, the spatial position of the ESD generator 7 is adjusted by the up and down movement of the sliding kit 3 on the device shaft 2 and the extension and retraction movement of the telescopic rod 5; finally, the discharge angle of the ESD generator 7 is adjusted by the angle adjustment mechanism to complete the precise positioning of the test point.

[0045] In summary, the electrostatic discharge testing device proposed in this utility model has the following advantages:

[0046] By setting up a combined structure of base, device shaft and drive device, the precise positioning of ESD generator is achieved, which solves the problems of inaccurate positioning and unstable angle when manually handheld testing, improves the accuracy and consistency of testing, and greatly improves testing efficiency.

[0047] By setting up sliding components, sleeves, telescopic rods, and angle adjustment mechanisms, multi-degree-of-freedom motion control of the ESD generator is achieved. Combined with the design of limit structures and anti-slip structures, the stability and reliability of the testing process are ensured, making the testing operation more flexible and precise, and effectively avoiding the problem of missing test points.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
