Description

Technical Field

[0001] This invention relates to the field of metal spectral detection technology, specifically to an impurity detection device for the purification process of high-purity metals. Background Technology

[0002] Based on the working principles of modern spectroscopic instruments, spectrometers can be divided into two main categories: classical spectrometers and novel spectrometers. Classical spectrometers are based on the principle of spatial dispersion; novel spectrometers are based on the principle of modulation. Furthermore, the detection of impurities in metal purification processes often requires the operation and detection of spectroscopic analyzers.

[0003] Currently, handheld spectrometers are often used to facilitate rapid impurity detection on production lines. This eliminates the need for sampling, significantly improving detection efficiency and making it more suitable for metal purification processes on production lines.

[0004] However, the following problems still exist: impurities, dust, or fingerprints on the detection end of the handheld spectrometer may lead to inaccurate detection results. Before use, it is often necessary to wipe it with a lint-free cloth moistened with anhydrous ethanol. However, there is a possibility that the wiping process is missed before detection, which can easily cause batch losses on the production line when a single detection result is incorrect and the data is statistically analyzed. Summary of the Invention

It features automatic cleaning of the detection end during the preheating stage, preventing missed wiping steps before detection, thus avoiding errors in initial detection results and ensuring accuracy. This, in turn, guarantees stable production line operations. It solves the problem that handheld spectrometers may have impurities, dust, or fingerprints on the detection end, leading to inaccurate results.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an impurity detection device for the high-purity metal purification process.

[0023] Example 1, a typical implementation of this application, such as Figure 1 As shown, an impurity detection device for a high-purity metal purification process includes a body 1, a detection mechanism 2 disposed on the body 1, and an auxiliary mechanism 3 disposed on the detection mechanism 2. The detection mechanism 2 includes a detection end 21, which performs impurity detection processing on the metal. The auxiliary mechanism 3 includes a cleanroom cloth strip 36, a scraper 37, and an anhydrous ethanol spray nozzle 310. The cleanroom cloth strip 36, the scraper 37, and the anhydrous ethanol spray nozzle 310 are installed on the detection end 21. During the preheating stage before operation, the anhydrous ethanol spray nozzle 310 sprays anhydrous ethanol to wet the cleanroom cloth strip 36. The scraper 37 pushes the wetted cleanroom cloth strip 36 to move on the detection end 21 for wiping.

[0024] When using this invention: First, the impurity detection device is turned on for preheating. Simultaneously, anhydrous ethanol is sprayed from the anhydrous ethanol nozzle 310, causing the anhydrous ethanol to soak the lint-free cloth strip 36. The scraper 37 moves the lint-free cloth strip 36 on the detection end 21, so that the lint-free cloth strip 36 soaked in anhydrous ethanol wipes the detection end 21. When the impurity detection device has finished preheating, the lint-free cloth strip 36 soaked in anhydrous ethanol has completed the wiping and cleaning of the detection end 21, so that the impurity detection device has completed the preheating stage before operation. Then, the operator holds the impurity detection device to detect metal. Thus, the cleaning of the detection end 21 is automatically completed during the preheating stage, avoiding the omission of wiping process and preventing the error of the detection result and statistics. This ensures the accuracy of the detection results and indirectly guarantees the stability of the production line.

[0025] Example 2, as Figures 2-4 As shown, the difference from the above embodiment is that the detection mechanism 2 also includes a display screen 22, the detection end 21 is fixedly installed on one side of the body 1, the display screen 22 is fixedly installed on the other side of the body 1, the detection end 21 has a concave structure, and side baffles are provided around the detection end 21.

[0026] Furthermore, a handle 23 is fixedly installed at the bottom of the machine body 1. The handle 23 is connected to the machine body 1 and is used for hand gripping. A trigger 24 is movably installed on the handle 23 and is electrically connected to the detection end 21. The trigger 24 is used to control the start and stop of detection by the detection end 21.

[0027] Furthermore, a standard block 25 is snapped onto the detection end 21. The size of the standard block 25 is larger than the size of the side baffle of the detection end 21, so that the standard block 25 is snapped onto the side baffle of the detection end 21. The standard block 25 is used to cover and calibrate the detection end 21 during the preheating stage.

[0028] When using the impurity detection device, the operator holds the handle 23, places the detection end 21 against the metal, presses the trigger 24, and uses the detection end 21 to detect and process the metal. The detection data is displayed on the display screen 22.

[0029] Example 3, as Figures 5-8As shown, the difference from the above embodiment is that the auxiliary mechanism 3 also includes a slide rail 31. Slide rails 31 are fixedly installed on the inner walls of both sides of the side baffle of the detection end 21. The length of the slide rail 31 is adapted to the length of both sides of the side baffle of the detection end 21. A moving part 32 is slidably fitted inside the slide rail 31. The thickness of the moving part 32 is greater than the thickness of the track of the slide rail 31.

[0030] Furthermore, each movable component 32 is rotatably fitted with multiple bearing seats 33, which are symmetrically distributed on both sides of each movable component 32. The bearing seats 33 on each movable component 32 are symmetrically distributed along the midpoint of the interval between the movable components 32. Each bearing seat 33 is provided with a snap-fit ​​groove. A take-up roller 34 is arranged between a set of bearing seats 33 that are symmetrically opposite to the midpoint of the interval between the movable components 32. The two ends of the take-up roller 34 are respectively snapped into the snap-fit ​​grooves of the set of bearing seats 33 that are symmetrically opposite to the midpoint of the interval between the movable components 32. A cloth roller 35 is arranged between another set of bearing seats 33 that are symmetrically opposite to the midpoint of the interval between the movable components 32. The two ends of the cloth roller 35 are respectively snapped into the snap-fit ​​grooves of the other set of bearing seats 33 that are symmetrically opposite to the midpoint of the interval between the movable components 32.

[0031] Furthermore, the cleanroom strip 36 is wound onto the cloth roller 35, and a scraper 37 is provided between the moving parts 32. The two ends of the scraper 37 are respectively fixedly installed on each of the moving parts 32. The scraper 37 is located between the take-up roller 34 and the cloth roller 35. The head end of the cleanroom strip 36 on the cloth roller 35 passes over the scraping surface of the scraper 37 and is wound onto the take-up roller 34, so that the scraper 37 presses the wound cleanroom strip 36 against the detection end 21.

[0032] Furthermore, each slide rail 31 is rotatably fitted with a fine screw 38, the length of which is adapted to the length of the slide rail 31. The fine screw 38 passes through the moving part 32 and is threadedly engaged with the moving part 32. Multiple servo motors 39 are fixedly installed on the machine body 1, the number of which is the same as the number of fine screws 38. Each servo motor 39 is poweredly connected to each fine screw 38.

[0033] Furthermore, an anhydrous ethanol nozzle 310 is provided between the moving parts 32. The anhydrous ethanol nozzle 310 is adjacent to the dust-free cloth strip 36 on the cloth roller 35. The nozzle of the anhydrous ethanol nozzle 310 is close to the dust-free cloth strip 36 on the cloth roller 35. A hose 311 is fixedly installed at the end of the anhydrous ethanol nozzle 310. One end of the hose 311 is connected to the anhydrous ethanol nozzle 310. The other end of the hose 311 passes through the side baffle of the detection end 21. The other end of the hose 311 extends into the machine body 1. The other end of the hose 311 is connected to the anhydrous ethanol supply system.

[0034] Furthermore, the anhydrous ethanol supply system is installed inside the body 1. The anhydrous ethanol supply system includes a micro liquid pump and a water tank. The water tank is fixedly installed inside the body 1. The micro liquid pump is installed inside the body 1. The micro liquid pump delivers the anhydrous ethanol in the water tank into the hose 311, and then delivers it into the anhydrous ethanol spray nozzle 310 through the hose 311.

[0035] Furthermore, a gear ring 312 is fixedly mounted on a single shaft seat 33, and a gear 313 is rotatably engaged on the moving part 32. The gear ring 312 meshes with the gear 313, and a micro motor 314 is fixedly mounted on the moving part 32. The micro motor 314 is poweredly connected to the gear 313.

[0036] During the preheating stage, the standard block 25 is first clipped onto the side baffle of the detection end 21, covering the detection end 21. Then, anhydrous ethanol is delivered to the anhydrous ethanol spray nozzle 310 via the hose 311. The anhydrous ethanol spray nozzle 310 sprays anhydrous ethanol to wet the dust-free cloth strip 36 on the cloth roller 35. Then, the micro motor 314 is started, driving the gear 313 to rotate. The gear 313 drives the gear ring 312 to rotate, which in turn drives the shaft seat 33 to rotate. The shaft seat 33 then drives the take-up roller. Rotate 34, and take-up roller 34 takes up the dust-free cloth strip 36, so that the dust-free cloth strip 36 that was just soaked in anhydrous ethanol moves to the position close to the scraper 37. Then start servo motor 39, servo motor 39 drives fine screw 38 to rotate, fine screw 38 drives moving part 32 to move in slide rail 31, so that moving part 32 drives scraper 37 to move. Scraper 37 pushes the dust-free cloth strip 36 soaked in anhydrous ethanol to wipe the detection end 21. After the preheating stage is completed, the impurity detection device can be operated to detect metal. When it is necessary to replace the cleanroom strip 36, remove the take-up roller 34 that is clipped to the bearing seat 33, and remove the cloth roller 35 and the take-up roller 34 together. Then, clip the cloth roller 35 with the new cleanroom strip 36 and the empty take-up roller 34 back onto the bearing seat 33.

[0037] Working principle of the invention: First, the impurity detection device is turned on for preheating. At the same time, anhydrous ethanol is sprayed from the anhydrous ethanol nozzle 310, which wets the lint-free cloth strip 36. The scraper 37 moves the lint-free cloth strip 36 on the detection end 21 so that the lint-free cloth strip 36 wetted with anhydrous ethanol wipes the detection end 21. When the impurity detection device is preheated, the lint-free cloth strip 36 wetted with anhydrous ethanol has completed the wiping and cleaning of the detection end 21, so that the impurity detection device completes the preheating stage before operation. Then, the operator holds the impurity detection device to detect metal. Thus, the cleaning of the detection end 21 is automatically completed during the preheating stage, avoiding the omission of wiping process and preventing the error of the detection result and statistics. This ensures the accuracy of the detection results and indirectly ensures the stability of the production line. When using the impurity detection device, the operator holds the handle 23, then places the detection end 21 against the metal, presses the trigger 24, and uses the detection end 21 to detect and process the metal. The detection data is displayed on the display screen 22. During the preheating stage, the standard block 25 is first clipped onto the side baffle of the detection end 21, covering the detection end 21. Then, anhydrous ethanol is delivered to the anhydrous ethanol spray nozzle 310 via the hose 311. The anhydrous ethanol spray nozzle 310 sprays anhydrous ethanol to wet the dust-free cloth strip 36 on the cloth roller 35. Next, the micro motor 314 is started, driving the gear 313 to rotate. The gear 313 drives the gear ring 312 to rotate, which in turn drives the shaft seat 33 to rotate. The shaft seat 33 then drives the take-up roller 34. The rotating take-up roller 34 takes up the cleanroom cloth strip 36, moving the cleanroom cloth strip 36 that was just soaked in anhydrous ethanol to the position against the scraper 37. Then, the servo motor 39 is started, and the servo motor 39 drives the fine screw 38 to rotate. The fine screw 38 drives the moving part 32 to move in the slide rail 31, so that the moving part 32 drives the scraper 37 to move. The scraper 37 pushes the cleanroom cloth strip 36 soaked in anhydrous ethanol to wipe the detection end 21. After the preheating stage is completed, the impurity detection device can be operated to detect metal. When it is necessary to replace the cleanroom strip 36, remove the take-up roller 34 that is clipped to the bearing seat 33, and remove the cloth roller 35 and the take-up roller 34 together. Then, clip the cloth roller 35 with the new cleanroom strip 36 and the empty take-up roller 34 back onto the bearing seat 33.
