Description

Technical Field

[0001] This utility model specifically relates to an electrostatic tester. Background Technology

[0002] The primary purpose of electrostatic discharge (ESD) testing is to detect the presence of static electricity on an object or material and to assess its tolerance and potential impact under ESD conditions. This helps ensure that electronic products are not damaged, malfunction, or cause safety issues due to ESD during manufacturing, storage, transportation, and use.

[0003] Most existing electrostatic discharge (ESD) testers have a simple structure. When not in use, they typically have a protective sleeve directly placed on the probe for protection. When in use, the protective sleeve is removed. However, removing the protective sleeve can easily cause friction and wear on the probe, thus reducing its lifespan. Furthermore, the protective sleeve needs to be stored separately after removal, which can easily lead to its loss. Therefore, to address the above technical problems, an ESD tester is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes an electrostatic tester where the protective sleeve will not cause wear to the probe, thus extending the probe's lifespan. Furthermore, it eliminates the need for additional storage of the protective sleeve, preventing its loss.

[0005] An electrostatic discharge (ESD) tester includes an ESD tester body and a protective mechanism, wherein the protective mechanism includes:

[0006] The connecting frame can be fitted and fixed to the upper part of the electrostatic tester body;

[0007] Protective sleeves are hinged to both ends of the connecting frame. When the two sets of protective sleeves are closed and rotated, they can form a cavity to accommodate the two sets of probes at the top of the electrostatic tester body. When the two sets of protective sleeves are opened and rotated outwards, they can open the two sets of probes.

[0008] A drive component is disposed on the connecting frame and connected to the two sets of protective sleeves, for driving the two sets of protective sleeves to close or rotate outward.

[0009] The beneficial effects of the above-mentioned electrostatic tester are as follows:

[0010] The two sets of protective sleeves can be closed and rotated by the drive component to store the two sets of probes into the storage cavity for protection. The two sets of probes can be opened by driving the two sets of protective sleeves to open. The protective sleeves do not come into contact with the probes during the protection or opening process, so the protective sleeves will not cause wear to the probes and improve the service life of the probes. The protective sleeves are always connected to the connecting frame, so there is no need to store the protective sleeves after the probes are opened, thus avoiding the loss of the protective sleeves.

[0011] In one embodiment, the drive assembly includes a rotating shaft and a transmission assembly. The rotating shaft is rotatably mounted on the connecting frame, and the transmission assembly connects the rotating shaft and the two sets of protective sleeves. The transmission assembly is used to convert the rotation of the rotating shaft into the closing or opening rotation of the two sets of protective sleeves.

[0012] In one embodiment, the transmission assembly includes a worm and a worm wheel; the worm is coaxially mounted on both ends of the rotating shaft, the two sets of worms have opposite rotation directions, and the worm wheel is coaxially mounted on the hinge shafts of the two sets of protective sleeves, with the two sets of worms meshing with the two sets of worm wheels respectively.

[0013] In one embodiment, a non-slip knob is coaxially mounted on the rotating shaft.

[0014] In one embodiment, both sets of protective sleeves are provided with a cleaning mechanism, which includes an inner brush ring and a moving component. The inner brush ring is slidably disposed on the inner sidewall of the protective sleeve, and when the probe is accommodated in the receiving cavity, the inner brush ring is coaxially located above the probe. The moving component connects the protective sleeve and the inner brush ring and is used to drive the inner brush ring to slide along the probe axis.

[0015] In one embodiment, the moving component includes a screw; a guide groove is provided on the inner sidewall of the protective sleeve, a guide block is provided on the circumferential side of the inner brush, the guide block is slidably disposed in the guide groove, and the screw is rotatably disposed on the protective sleeve, with one end extending into the guide groove and threadedly connected to the guide block.

[0016] In one embodiment, the protective sleeve is made of a transparent material. Attached Figure Description

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] Please see Figures 1 to 3 One embodiment of an electrostatic discharge (ESD) tester includes an ESD tester body 10 and a protective mechanism. The protective mechanism includes a connecting frame 20, a protective sleeve 30, and a drive assembly. Specifically, the ESD tester body 10 is existing technology, such as the EFM-022 model, and its working principle will not be described in detail.

[0030] The connecting frame 20 can be sleeved and fixed to the upper part of the electrostatic tester body 10. Protective sleeves 30 are hinged to both ends of the connecting frame 20. The two sets of protective sleeves 30 can be closed and rotated to form a receiving cavity that accommodates the two sets of probes 101 at the top of the electrostatic tester body 10. The two sets of protective sleeves 30 can be opened by rotating outwards. The driving component is located on the connecting frame 20 and connected to the two sets of protective sleeves 30, used to drive the two sets of protective sleeves 30 to close or rotate outwards.

[0031] In the above embodiments, when the device is not in use, the two sets of protective sleeves 30 can be driven to close and rotate by the driving component to store the two sets of probes 101 into the storage cavity for protection. When the device is in use, the two sets of protective sleeves 30 can be driven to open and rotate by the driving component to open the two sets of probes 101. The protective sleeves 30 do not contact the probes 101 during the process of protecting or opening the probes 101, so the protective sleeves 30 will not cause wear to the probes 101, thus improving the service life of the probes 101. Moreover, the protective sleeves 30 are always connected to the connecting frame 20. After opening the probes 101, there is no need to store the protective sleeves 30 separately, thus avoiding the loss of the protective sleeves 30.

[0032] Please refer to Figures 1 to 3 Figures 1 to 3 In one embodiment, the driving component includes a rotating shaft 40 and a transmission component. The rotating shaft 40 is rotatably arranged on the connecting frame 20. The transmission component connects the rotating shaft 40 and two sets of protective sleeves 30, and is used to convert the rotation of the rotating shaft 40 into the closing or outward rotation of the two sets of protective sleeves 30. By rotating the rotating shaft 40, the two sets of protective sleeves 30 can be driven to close or rotate outward, which is convenient and labor-saving.

[0033]

[0033] Specifically, the transmission component includes a worm 401 and a worm wheel 402. Worms 401 are coaxially arranged at both ends of the rotating shaft 40, and the helix directions of the two worms 401 are opposite. Worm wheels 402 are coaxially arranged on the hinge shafts 301 of the two sets of protective sleeves 30, and the two worms 401 are respectively engaged with the two worm wheels 402. It can be understood that rotating the rotating shaft 40 drives the two worms 401 to rotate. When the two worms 401 rotate and are engaged with the two worm wheels 402, the two worm wheels 402 can be driven to rotate. When the two worm wheels 402 rotate, the hinge shafts 301 can be driven to rotate, so that the two sets of protective sleeves 30 close or rotate outward. And through the cooperation of the worm 401 and the worm wheel 402, when the rotation of the rotating shaft 40 stops, the two sets of protective sleeves 30 can be fixed, thereby improving the stability of the two sets of protective sleeves 30 when protecting or opening the probe 101.

[0034]

[0034] Furthermore, an anti-slip knob 403 is coaxially arranged on the rotating shaft 40. By setting the anti-slip knob 403, it is convenient to drive the rotation of the rotating shaft 40, and the phenomenon of slipping can be avoided, and it is convenient to drive the rotation of the rotating shaft 40. [[ID={10}]]

[0035] Please refer to Figure 1 、 Figure 2 and Figure 4 Figure 4 In one embodiment, cleaning mechanisms are arranged on both sets of protective sleeves 30. The cleaning mechanism includes an inner brush ring 50 and a moving component. The inner brush ring 50 is slidably arranged on the inner side wall of the protective sleeve 30, and when the probe 101 is accommodated in the storage cavity, the inner brush ring 50 is coaxially located above the probe 101. The moving component connects the protective sleeve 30 and the inner brush ring 50, and is used to drive the inner brush ring 50 to slide along the axial direction of the probe 101.

[0036]

[0036] In the above embodiment, when the two sets of protective sleeves 30 close and rotate to accommodate the probe 101 in the storage cavity, at this time, by driving the inner brush ring 50 to slide along the axial direction of the probe 101 through the moving component, the inner brush ring 50 can be sleeved on the probe 101 to clean the outer peripheral wall of the probe 101, which is convenient and labor-saving for cleaning the probe 101.

[0037] [[ID=2{4}]]Please refer to Figure 4In one embodiment, the moving component includes a screw 501; a guide groove 302 is provided on the inner side wall of the protective sleeve 30, and a guide block 502 is provided around the inner brush ring 50. The guide block 502 is slidably disposed in the guide groove 302, and the screw 501 is rotatably disposed on the protective sleeve 30, with one end extending into the guide groove 302 and threadedly connected to the guide block 502.

[0038] In the above embodiment, by rotating the screw 501 and threadedly engaging the guide block 502, the guide block 502 can be driven to move the inner brush ring 50 to clean the probe 101. By rotating the screw 501 and threadedly engaging the guide block 502 in the opposite direction, the guide block 502 can be driven to move the inner brush ring 50 in the opposite direction to separate it from the probe 101. It is convenient to drive the inner brush ring 50 to move to clean the probe 101 or to separate it from the probe 101.

[0039] Furthermore, the protective sleeve 30 is made of transparent material. This facilitates observation of whether the inner brush ring 50 separates from the probe 101 after cleaning, and avoids the two sets of protective sleeves 30 being unable to open the probe 101.

[0040] The specific implementation method of the above-mentioned electrostatic tester is as follows:

[0041] When the device is not in use, rotating the shaft 40 drives the two sets of worm gears 401 to rotate. The rotation of the two sets of worm gears 401 engages with the two sets of worm wheels 402, driving the two sets of worm wheels 402 to rotate. The rotation of the two sets of worm wheels 402 drives the hinge shaft 301 to rotate, thereby closing the two sets of protective sleeves 30 to store the two sets of probes 101 into the storage cavity for protection. When the device is in use, rotating the shaft 40 in the opposite direction drives the two sets of worm gears 401 to rotate in the opposite direction, and the two sets of worm gears 401 engage with the two sets of worm wheels 402. This drives the two sets of worm gears 402 to rotate in opposite directions. The opposite rotation of the two sets of worm gears 402 drives the hinge shaft 301 to rotate in opposite directions, thereby causing the two sets of protective sleeves 30 to open the two sets of probes 101. The protective sleeves 30 do not contact the probes 101 during the process of protecting or opening the probes 101. The protective sleeves 30 will not cause wear to the probes 101, thus improving the service life of the probes 101. Moreover, the protective sleeves 30 are always connected to the connecting frame 20. After opening the probes 101, there is no need to store the protective sleeves 30 separately, thus avoiding the loss of the protective sleeves 30.

[0042] When the probe 101 needs to be cleaned, drive the two sets of protective sleeves 30 to close so that the probe 101 is stored in the storage cavity. At this time, the inner brush ring 50 is coaxially located above the probe 101. Then, rotate the screw 501 and the guide block 502 to drive the guide block 502 to move the inner brush ring 50 to clean the probe 101. After cleaning, rotate the screw 501 and the guide block 502 in the opposite direction to drive the guide block 502 to move the inner brush ring 50 in the opposite direction and separate it from the probe 101. It is convenient to drive the inner brush ring 50 to move to clean the probe 101 or to separate it from the probe 101.
