[0002] In the current electrical tracking resistance test, it is necessary to prepare a 6mm electrical tracking resistance sample. When preparing the electrical tracking resistance sample, the surface of the sample needs to be polished and cleaned with alcohol after the sample is cut.

[0003] However, the above processes are generally all done manually, especially the polishing process. The polishing required for the electrical tracking resistant samples is usually relatively low, relying on the experimenter to hold the sample in place while using a small, low-power polishing tool to polish each sample individually. Because the polishing head of traditional polishing tools is small, this manual operation is very inconvenient and cannot cover as much of the sample surface as possible, resulting in low polishing efficiency.

[0019] Combined with appendix Figure 1 To be continued Figure 2 This embodiment proposes a device for processing traceless electrical trace samples, including a housing 1 with a top opening and a grinding assembly; a sample placement platform 2 is provided at the bottom inside the housing 1, which is used to place traceless electrical trace samples. The housing 1 includes symmetrically arranged side plates, each of which is provided with a limiting groove 3, and each limiting groove 3 is provided with a spring 4, the bottom end of the spring 4 abutting against the bottom of the limiting groove 3.

[0020] The grinding assembly includes a roller 6, an operating lever 7, and a motor 8. The operating lever 7 and the motor 8 are located on opposite sides of the roller 6, and a grinding section 9 is provided on the surface of the roller 6. The output shaft of the motor 8 is connected to the central shaft of the roller 6. A first limiting block 11 is fixedly provided at the end of the motor 8 away from the roller 6. The first limiting block 11 slides in a limiting groove 3 on the same side and abuts against the top of the spring 4 inside the limiting groove 3. A second limiting block 12 is fixedly provided on the operating lever 7. The second limiting block 12 slides in a limiting groove 3 on the other side and abuts against the top of the spring 4 inside the limiting groove 3. A sleeve 10 is provided on the side of the second limiting block 12 facing the roller 6, and the sleeve 10 rotates in conjunction with the central shaft of the roller 6.

[0021] The working principle of the electrostatic discharge (ESD) resistant sample processing device in this embodiment is as follows: Initially, the spring 4 in the limiting groove 3 lifts the limiting block, stabilizing the roller 6 in its initial position. When it is necessary to polish the ESD resistant sample, the sample is placed on the sample placement platform 2, and then the operating lever 7 is pressed down until the polishing part 9 on the surface of the roller 6 contacts the ESD resistant sample. Then, the motor 8 is started, and the motor 8 drives the central shaft of the roller 6 to rotate, thereby driving the polishing part 9 to polish the ESD resistant sample through the roller 6. During the polishing process, the ESD resistant sample can be dragged to polish different areas on the sample.

[0022] Obviously, compared with the existing technology of low efficiency in the process of processing electrical tracking samples, in this embodiment, the operator can press the operating lever 7 to press down the roller 6, and the roller 6 driven by the motor 8 can be used to easily polish the electrical tracking sample.

[0023] Preferably, the polishing part 9 is sandpaper, which is fixed to the circumferential surface of the roller 6. The grit of the sandpaper can be selected according to the polishing requirements. In addition, in order to ensure that the roller 6 rotates smoothly and stably, a bearing can be provided between the sleeve 10 and the central axis of the roller 6.

[0024] In a preferred embodiment, the system further includes a support screw 13 and a first fastening bolt 14. The sample placement platform 2 has a through hole. One end of the support screw 13 is fixedly connected to the bottom of the housing 1. The first fastening bolt 14 is threaded into the support screw 13, and the other end of the support screw 13 passes through the through hole, so that the bottom of the sample placement platform 2 abuts against the upper surface of the first fastening bolt 14. In this embodiment, the cooperative design of the support screw 13 and the first fastening bolt 14 allows for adjustment of the height of the sample placement platform 2, thereby adjusting the placement height and horizontal level of the trace resistance sample.

[0025] The adjustment principle is as follows: when the first fastening bolt 14 rotates relative to the support screw 13, its height changes. Generally, there are two or more support screws 13, and correspondingly two or more first fastening bolts 14. The sample placement platform 2 is supported by the first fastening bolts 14. At this time, the support height of the sample placement platform 2 and its levelness can be adjusted by simultaneously adjusting the height of multiple first fastening bolts 14.

[0026] Further improvements include a second fastening bolt, which is located on the upper side of the sample placement platform 2 and threadedly engages with the support screw 13. The through-hole on the sample placement platform 2 and the support screw 13 have a clearance fit, which may cause the sample placement platform 2 to wobble during grinding. Therefore, in this embodiment, the sample placement platform 2 can be clamped by the first fastening bolt 14 and the second fastening bolt to ensure its stability.

[0027] In other embodiments, the sample placement platform 2 includes a fixed platform 21 and a movable platform 22, with the movable platform 22 slidably disposed on the fixed platform 21. A handle 20 is provided at one end of the movable platform 22. In this embodiment, the operator does not need to drag the EDM sample directly, but can drag the movable platform 22 through the handle 20 to change the position of the EDM sample, thereby polishing different areas on the EDM sample.

[0028] In a preferred embodiment, an air gun 15 is provided on the housing 1, and the air gun 15 faces the sample placement platform 2. The air gun 15 can be used to blow away the surface of the ESD sample after grinding, thereby facilitating subsequent cleaning.

[0029] Furthermore, the housing 1 is also provided with a liquid inlet 16 and a liquid outlet 17. The height of the liquid inlet 16 is higher than the height of the sample placement platform 2, and the liquid outlet 17 is located at the bottom of the housing 1. The liquid inlet 16 can be connected to a delivery device for cleaning liquids such as alcohol, so that the housing 1 can store a certain level of alcohol (generally the level above the trace resistance sample), thereby facilitating the cleaning of the trace resistance sample. The liquid outlet 17 is used to drain excess liquid after cleaning. Generally, a valve is provided at the liquid outlet 17 to open and close the liquid outlet 17.

[0030] In a preferred embodiment, the sides of the housing 1 can be made of materials such as glass or acrylic to ensure transparency. The transparent sides of the housing 1 allow the operator to easily observe the polishing process of the ESD sample. Combined with the aforementioned embodiments, the cleaning process of the ESD sample by the air gun 15 and the liquid level inside the housing 1 can also be observed to determine whether the cleaning requirements for the ESD sample are met.

[0031] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
