Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to an antistatic dust-free paper detection device. Background Technology

[0002] Antistatic cleanroom wipes are a key consumable in cleanrooms, widely used for wiping equipment, workbenches, container inner walls, and the products themselves. Their performance directly affects the stability of the production process and the final quality of the product. The core requirement for their performance lies in excellent antistatic properties, meaning they do not easily generate static electricity during the wiping process, thus avoiding static electricity attracting dust or damaging precision components.

[0003] Current technologies for testing the performance of antistatic cleanroom paper generally suffer from outdated methods. Electrostatic performance testing typically relies on operators holding a handheld electrometer to measure samples after simple manual rubbing. This method is severely limited by the operator's force, rubbing frequency, and stroke, and is greatly influenced by random human factors, resulting in poor repeatability and low comparability of test results. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional testing methods often rely on operators using handheld devices for friction and measurement, which has drawbacks such as significant human influence, inconsistent testing conditions, and poor repeatability.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: An antistatic cleanroom paper testing device, comprising: The base has several supporting legs fixedly connected to its lower end, and its upper end is sequentially fixed to a first mounting frame, a second mounting frame, and a third mounting frame in a horizontal direction. A mobile support mechanism, which is mounted on a base, is used to support and transport the dust-free paper sample to be tested; An electrostatic eliminator, mounted on a first mounting frame, is used to initially neutralize the static electricity of the conveyed clean paper sample. A simulated friction mechanism, mounted on a second mounting frame, is used to simulate friction on the surface of a static-neutralized dust-free paper sample by mechanical means. A non-contact electrostatic sensor is mounted on a third mounting bracket, with its lower probe pointing vertically towards the base surface, used to detect the amount of electrostatic charge on the surface of a dust-free paper sample after simulated friction.

[0006] Furthermore, the movable support mechanism includes a first motor and a support base. The first motor is horizontally mounted on the outside of the base. A sliding groove is provided at the upper end of the base. A screw rod that is horizontally rotatably connected to the output end of the first motor is fixedly connected to the screw rod.

Rollers are rotatably connected to both sides of the support base through bearings. The support base moves horizontally on the base through the rollers. A mounting plate integral with the support base is symmetrically provided at the upper end of the support base. Fastening components are provided on the mounting plates for pressing and securing the dust-free paper sample on the support base.

[0007] Furthermore, the fastening assembly includes an adjusting rod and a pressure plate. The adjusting rod passes vertically through the mounting plate and is threadedly connected to the mounting plate. A knob is fixedly connected to the upper end of the adjusting rod, and the lower end of the adjusting rod is rotatably connected to the pressure plate through a limiting piece. The pressure plate is movably disposed between the support base and the mounting plate. A first limiting rod symmetrically distributed on both sides of the adjusting rod is fixedly connected to the upper end of the pressure plate. The upper end of the first limiting rod passes vertically through the mounting plate and is fixedly connected to a limiting piece.

[0008] Furthermore, the electrostatic elimination component includes an ion bar and a high-voltage generator. Several of the ion bars are fixedly installed on the top surface of the inner wall of the first mounting frame, and the high-voltage generator is fixedly installed on the upper end of the first mounting frame. The ion bars and the high-voltage generator are connected by a connecting wire.

[0009] Furthermore, the simulated friction mechanism includes a lifting plate, a mounting plate, a rotating shell, and a friction plate. A hydraulic rod is vertically fixed to the upper end of the second mounting frame. The piston rod at the lower end of the hydraulic rod vertically passes through the second mounting frame and is fixed to the upper end of the lifting plate. A second limiting rod symmetrically distributed on both sides of the hydraulic rod is fixed to the upper end of the lifting plate. The upper end of the second limiting rod vertically passes through the second mounting frame and is fixed to a limiting plate. A vertical plate is symmetrically fixed to the lower end of the lifting plate. The mounting plate is fixed to the lower end of the vertical plate.

[0018] like Figure 1-5As shown, an antistatic cleanroom paper testing device includes: a base 1, with several support legs 2 fixedly connected to the lower end of the base 1, and the upper end of the base 1 sequentially fixed to a first mounting frame 102, a second mounting frame 103, and a third mounting frame 104 in a horizontal direction; a controller 7 is installed at the front end of the base 1; a movable support mechanism, installed on the base 1, for supporting and conveying the cleanroom paper sample to be tested; an electrostatic elimination component, installed on the first mounting frame 102, for initially neutralizing the electrostatic charge on the conveyed cleanroom paper sample; a simulated friction mechanism 5, installed on the second mounting frame 103, for simulating friction on the surface of the electrostatically neutralized cleanroom paper sample by mechanical means; and a non-contact electrostatic sensor 6, installed on the third mounting frame 104, with its lower probe pointing vertically towards the surface of the base 1, for detecting the amount of electrostatic charge on the surface of the cleanroom paper sample after simulated friction.

[0019] like Figure 1 , 3 As shown, the movable support mechanism includes a first motor 301 and a support base 303. The first motor 301 is horizontally mounted on the outside of the base 1. A groove 101 is provided on the upper end of the base 1. A screw 302 is fixedly connected to the output end of the first motor 301 and rotatably connected to the groove 101. A slider 304 is fixedly connected to the lower end of the support base 303, threadedly connected to the screw 302 and slidably disposed in the groove 101. Rollers 310 are rotatably connected to both sides of the support base 303 via bearings. The support base 303 moves horizontally on the base 1 via the rollers 310. A mounting plate 305 is symmetrically provided on the upper end of the support base 303. Each mounting plate 305 is provided with a fastening component for pressing the dust-free paper sample on the support base 303. The fastening component includes an adjustment mechanism. The adjustment rod 306 and the pressure plate 308 are arranged in a series of components. The adjustment rod 306 passes vertically through the mounting plate 305 and is threadedly connected to the mounting plate 305. A knob 307 is fixedly connected to the upper end of the adjustment rod 306. The lower end of the adjustment rod 306 is rotatably connected to the pressure plate 308 through a limiting piece. The pressure plate 308 is movably disposed between the support base 303 and the mounting plate 305. A first limiting rod 309 symmetrically distributed on both sides of the adjustment rod 306 is fixedly connected to the upper end of the pressure plate 308. The upper end of the first limiting rod 309 passes vertically through the mounting plate 305 and is fixedly connected to a limiting piece. The clean paper sample is fixed on the support base 303 by a fastening assembly. Driven by the first motor 301, the support base 303 uses the rolling of the roller 310 on the base 1 to drive the clean paper sample to move horizontally. The support base 303 does not contact the surface of the base 1.

[0020] like Figure 1 , 2As shown, the electrostatic elimination assembly includes an ion bar 4 and a high-voltage generator 401. Several ion bars 4 are fixedly installed on the top surface of the inner wall of the first mounting frame 102, and the high-voltage generator 401 is fixedly installed on the upper end of the first mounting frame 102. The ion bars 4 and the high-voltage generator 401 are connected by a connecting wire. After the high-voltage generator 401 is started, the ion bars 4 under the clean paper sample achieve initial electrostatic neutralization of the clean paper sample.

[0021] like Figure 1 , 4 As shown in Figure 5, the simulated friction mechanism 5 includes a lifting plate 502, a mounting plate 505, a rotating shell 508, and a friction plate 510. A hydraulic rod 501 is vertically fixed to the upper end of the second mounting frame 103. The piston rod at the lower end of the hydraulic rod 501 vertically passes through the second mounting frame 103 and is fixed to the upper end of the lifting plate 502. A second limiting rod 503 symmetrically distributed on both sides of the hydraulic rod 501 is fixed to the upper end of the lifting plate 502. The upper end of the second limiting rod 503 vertically passes through the second mounting frame 103 and is fixed to a limiting piece. A vertical plate 504 is symmetrically fixed to the lower end of the lifting plate 502. The mounting plate 505 is fixed to the lower end of the vertical plate 504. A second motor 507 disposed between the vertical plates 504 is vertically fixed to the upper end of the mounting plate 505. The lower end of the 5 has a groove 506. The rotating shell 508 is fixed to the output end of the second motor 507 and rotatably disposed in the groove 506. The rotating shell 508 has an installation groove 509. A spring 512 is provided in the installation groove 509. A sliding rod 511 is vertically fixed to the upper end of the friction plate 510. The upper end of the sliding rod 511 slides vertically in the installation groove 509 through a limiting piece and is fixed to the lower end of the spring 512. The lower end of the friction plate 510 is covered with a standard friction material 513. After the support seat 303 moves the dust-free paper sample to the lower side of the second mounting frame 103, the standard friction material 513 at the lower end of the friction plate 510 is driven by the hydraulic rod 501 to abut against the surface of the dust-free paper sample. Then, under the drive of the second motor 507, the dust-free paper sample is subjected to friction simulation.

[0022] In use, the dust-free paper sample is placed on the support base 303. The knob 307 is turned to drive the adjusting rod 306 to rotate. Through the limiting effect of the first limiting rod 309 sliding vertically on the mounting plate 305, the adjusting rod 306 rotates and drives the pressure plate 308 to descend vertically and press the dust-free paper sample onto the support base 303. The starting device, under the control of the controller 7, drives the screw 302 to rotate at the output end of the first motor 301, which in turn drives the slider 304 to slide horizontally in the slide groove 101, which in turn drives the support 303 to move horizontally on the base 1 via the roller 310. The sample is transported to the lower side of the first mounting frame 102. The electrostatic elimination component is started, and the high voltage generator 401 supplies power to the ion wind bar 4, generating ion wind to sweep the sample surface, thereby eliminating the initial static charge of the sample. Then the support 303 continues to move to transport the sample to the lower side of the second mounting frame 103. The simulated friction mechanism 5 starts to work. The controller 7 controls the piston rod of the hydraulic rod 501 to extend downward, thereby pushing the lifting plate 502 and its lower end components to descend until the standard friction material 513 at the lower end of the friction plate 510 contacts the sample surface. Under the combined action of the hydraulic rod 501 and the spring 512, the standard friction material 513 is pressed to squeeze the sample surface. At the same time, the second motor 507 starts. Under the control of the controller 7, the second motor 507 drives the rotating shell 508 and the friction plate 510 to rotate, thereby causing the standard friction material 513 to simulate friction on the sample surface. The standard friction material 513 can be made of stainless steel, polyurethane or glass, to simulate the performance of cleanroom paper under different working conditions such as wiping metal equipment, plastic shells or optical glass. After the friction is completed, the hydraulic rod 501 lifts the lifting plate 502 and the components at its lower end to reset. Then the support seat 303 continues to move forward to transport the rubbed sample to the lower side of the third mounting frame 104. The non-contact electrostatic sensor 6 accurately measures the static charge on its surface and outputs the data. The entire testing process is programmed and controlled by controller 7, which effectively avoids errors caused by human operation, and the test results have high repeatability and good reliability.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, 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.
