Electrode polishing is a key method of electrode surface treatment, removing oxides and impurities from the electrode surface, making it smoother, increasing surface roughness, and increasing the active surface area, thereby improving detection sensitivity and accuracy. Generally, electrode surface treatment involves the following steps: Cleaning the electrode surface with deionized water and ethanol to remove dust and impurities; Polishing the electrode surface through mechanical or electrochemical polishing to remove residual oxides and impurities and adjust the surface topography and roughness; Finally, rinsing with deionized water and drying.

[0003] Traditionally, transducer electrode polishing is performed manually using sandpaper.

[0023] The following describes the specific embodiments of the present invention in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, not limiting, of the scope of the present invention.

[0024] Specific embodiment 1: Please refer to Figure 1-4 A transducer electrode sheet grinding device includes: a workbench 100 and an electric control box 110 installed on the workbench 100, a rotating shaft grinding platform 200 and an adsorption fixing platform 300, wherein the adsorption fixing platform 300 is arranged on the lower side of the execution end of the rotating shaft grinding platform 200, and is used to load and fix the electrode sheet. After grinding is completed, the electrode sheet can be rebounded to the initial position to facilitate the removal of the electrode sheet; this grinding device can control the grinding depth. The grinding device can be used to complete the automatic grinding processing of the entire circumference of the electrode sheet made of beryllium copper or other materials with a thickness between 0.2mm and 1mm, which can reduce labor intensity and improve production efficiency.

[0025] The rotating shaft grinding platform 200 includes a base 210, a column 220, a grinding head 230, a drill chuck 240, a spindle 250, a locking device 260, a main motor 270, a servo motor 280, and a spindle head frame 290. The base 210 is installed on the workbench 100, and the column 220 is fixed on the base 210 to provide stable support. The spindle 250 is installed on the column 220 through the spindle head frame 290 and the locking device 260. The grinding head 230 is arranged at the lower end of the spindle 250 through the drill chuck 240 and is used for grinding the surface of the electrode sheet; the main motor 270 and the servo motor 280 are connected to the upper end of the spindle 250 to control the speed, torque, and position of the grinding head 230 to achieve up and down floating during the grinding process, thereby ensuring the control of the grinding force of the electrode sheet.

[0026] During implementation, the grinding head 230 uses a scouring pad grinding head, which can grind the electrode sheet without damaging the body while ensuring durability.

[0027] The adsorption and fixing platform 300 includes a vacuum suction cup assembly 310 and a positioning platform. The vacuum suction cup assembly 310 includes an execution end silicone suction cup 311, a vacuum generating end, and a spring arranged between the silicone suction cup 311 and the vacuum generating end. Under the action of the spring, the silicone suction cup 311 can reciprocate relative to the vacuum generating end.

[0028] The positioning platform is a mounting frame which is arranged in sequence from top to bottom, including a positioning plate 320, a supporting plate 330, an upper contour sleeve 340, a fixing plate 350, a lower contour sleeve 360 ​​and a bottom plate 370. The upper end of the positioning plate 320 is provided with a groove which is adapted to the size of the electrode sheet. The groove reinforces the electrode sheet during the grinding process to prevent the electrode sheet from displacement. Four suction cup holes are evenly arranged on the bottom wall of the groove. The vacuum suction cup assembly 310 is provided with four vacuum suction cup assemblies 310 and the vacuum suction cup assembly 310 is arranged corresponding to the suction cup holes. Specifically, the vacuum suction cup assembly 310 is fixedly mounted on the fixing plate 350. The upper part of the vacuum suction cup assembly 310 passes through the suction cup hole so that the silicone suction cup 311 extends into the groove. It can be understood that in order to enable the silicone suction cup 311 to reciprocate smoothly, the inner diameter of the suction cup hole should be larger than the outer diameter of the silicone suction cup 311. It should also be noted that in order to ensure balanced adsorption force, the four vacuum suction cup assemblies 310 should be at the same horizontal height.

[0029] In addition, in this embodiment, the positioning plate 320 , the supporting plate 330 , the fixing plate 350 , and the bottom plate 370 are all circular plate-shaped structures, and the smooth surface can reduce the occurrence of bumps.

[0030] In other embodiments, the number of the vacuum suction cup assembly 310 and the suction cup holes is not limited to the four mentioned above, and the number of the vacuum suction cup assembly 310 and the suction cup holes can be increased or decreased depending on the specific situation.

[0031] This polishing device also includes a vacuum generating device, which includes a PU tube, a solenoid valve, and a vacuum generator. The vacuum generator is connected to the vacuum generating end of the vacuum suction cup assembly 310 through the PU tube and the solenoid valve, so that the silicone suction cup 311 of the vacuum suction cup assembly 310 generates suction for fixing the electrode sheet.

[0032] The electric control box 110 is provided with a PLC control system, which is electrically connected to the rotating shaft polishing platform 200 and the vacuum generating device for controlling the rotating shaft polishing platform 200 and the adsorption fixing platform 300 to complete the electrode sheet surface polishing process.

[0033] The working principle of this grinding device:

[0034] The electrode sheet is manually placed on the positioning plate 320, which has a groove design for positioning. The vacuum suction cup assembly 310 generates negative pressure, and the suction cup generates adsorption force to fix the electrode sheet. The scouring pad grinding head 230 is installed through the drill chuck 240. The lifting and rotation of the main shaft 250 are controlled by the PLC control system. The main shaft 250 drives the scouring pad grinding head 230 to rotate and is used to grind the surface of the electrode sheet. Press the start button of the electric control box 110, the vacuum suction cup assembly 310 generates negative pressure to fix the electrode sheet, and the scouring pad grinding head 230 starts to rotate and automatically descends to the surface of the electrode sheet for grinding. When grinding is completed, the spindle 250 stops rotating when it moves upward. The adsorption force of the negative pressure of the vacuum suction cup assembly 310 causes the electrode sheet to automatically rebound by the spring of the vacuum suction cup assembly 310, floating the electrode sheet above the positioning plate 320, and can be directly taken to complete the entire grinding process.

[0035] Actual production has proven that using this transducer electrode polishing device takes an average of 20 seconds to polish an electrode. Manual operation is solely responsible for placing and removing the electrode, while the device automatically completes the adsorption, fixation, and polishing operations. Polishing does not damage the electrode surface or cause deformation, achieving a 100% pass rate. The transducer electrode polishing device is simple and convenient to operate, safe and reliable, and highly adaptable. It increases polishing efficiency by 15 times compared to manual operation, ensuring smooth and on-time completion of production projects.

[0036] Through this technical solution, the main part of the electrode sheet grinding equipment is designed to be a rotating shaft grinding platform and an adsorption fixing platform to achieve grinding and fixing. The rotating shaft grinding platform drives the rotation of the grinding head to process the surface of the electrode sheet. At the same time, in order to prevent the electrode sheet from shifting during the grinding process, the electrode sheet is doubly fixed with a silicone suction cup and a card slot design to prevent the electrode sheet from bouncing off during the grinding process. A spring is added to the vacuum suction cup assembly of the adsorption fixing platform. When the air pressure disappears, the spring automatically rebounds, floating the electrode sheet above the positioning plate, which can be directly taken out. The operation is simple, fast and convenient.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
