Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal coating technology, specifically a functional device for rapid cooling of an ion source and electrostatic adsorption. Background Technology
[0002] An ion source is a device that ionizes gases or other substances to generate ions. These ions can be used in mass spectrometry, particle accelerators, materials characterization, and other fields. In current composite copper foil manufacturing methods (magnetron sputtering + water plating), BOPP materials have relatively high toughness. Since water plating mainly increases thickness, adhesion is primarily affected by the underlying copper film, i.e., magnetron sputtered copper. To improve film adhesion, an ion source plays an essential role. Magnetron sputtering further achieves high speed, low temperature, and low damage.
[0003] Existing technology CN212069066U discloses a cooling system for a plasma power supply in the production of ultrafine toner. The technical solution discloses that "this utility model discloses a cooling system for a plasma power supply in the production of ultrafine toner, including a coolant storage device, a water pump, a water inlet assembly, a water outlet assembly, a water-cooled plate, and a power module. The coolant storage device stores coolant. The inlet of the water pump is connected to the coolant storage device, the outlet of the water pump is connected to the water inlet assembly, the outlet of the water inlet assembly is connected to the inlet of the water-cooled plate, the outlet of the water-cooled plate is connected to the water outlet assembly, and the outlet of the water outlet assembly is connected to the coolant storage device. The power module is fixedly mounted on the water-cooled plate. The water pump pumps the coolant from the coolant storage device to the water-cooled plate to cool the power module. After heat exchange, the coolant flows back to the coolant storage device through the water outlet assembly. The water-cooled plate effectively isolates the coolant from the electronic components inside the power module, quickly removing heat to prevent high-temperature damage to the electronic components while preventing damage from the coolant and the water vapor generated by the vaporization of the coolant."
[0004] Although existing technologies have disclosed cooling systems for plasma power supplies produced from ultrafine toner, there are still some shortcomings. Specifically, in actual production operations, the efficiency of the cooling system is often limited by the circulation speed and heat exchange capacity of the coolant. Existing technologies use natural air cooling, but after long-term operation, the heat dissipation effect of the cooling system will be greatly reduced, causing the temperature of the ion source to rise continuously, which in turn affects its stability and service life. Utility Model Content
[0005] The purpose of this invention is to provide a functional device for rapid cooling of an ion source and electrostatic adsorption, so as to solve the problems raised in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: The functional device includes an electrostatic plate, a cathode device mounted on one side of the electrostatic plate, an anode device mounted inside the cathode device, an insulating device mounted on one side of the cathode device, a magnetic circuit module device mounted on one side of the insulating device, a cooling device mounted inside the magnetic circuit module device, a gas path device mounted on one side of the magnetic circuit module device, a pressure block mounted on one side of the gas path device, and a water path device and a conductive device mounted on one side of the pressure block. The cathode device releases electrons to form negative ions, while the anode attracts ions, maintaining the electric field inside the ion source and helping to accelerate the generation of ions. The gas path device can be used for rapid vacuuming or introducing specific gases to ensure the stability and reliability of the coating environment. The pressure block ensures the tight connection of all components inside the device. The conductive device effectively conducts current, providing the necessary electrical energy to the ion source and ensuring the stability and effectiveness of the ionization process.
[0007] The cathode device includes a cathode base plate, on which an outer cathode and an inner cathode are disposed. The magnetic circuit module device has a protrusion on one side and a groove on its surface. The magnetic circuit module device is made of magnets and a magnetic yoke. The magnetic circuit module device enhances the electrostatic adsorption effect by adjusting the distribution of the magnetic field to increase the charge density on the electrostatic plate, thereby improving the adsorption strength.
[0008] The anode device is located on the inner wall of the cathode device, and an insulating ceramic is disposed on the outer side of the anode device. A light source is disposed in the gap between the insulating ceramic and the anode device. The main function of the insulating ceramic is to provide electrical insulation to prevent direct current leakage between the cathode and anode. This ensures the effectiveness and stability of the electric field and prevents equipment damage. The ceramic material has high heat resistance and can operate normally in high-temperature environments, thereby protecting the internal electrodes and circuits from overheating. The light source provides the necessary energy to excite the gas molecules inside the ion source, causing them to ionize and form glow plasma. After the glow plasma is formed, the light source continues to provide excitation energy to maintain the stability and continuity of the plasma.
[0009] The insulating device is located on one side of the cathode base plate and has a through groove. The insulating device is made of polytetrafluoroethylene (PTFE). PTFE has good heat resistance, excellent chemical stability, and waterproof and non-stick properties. The insulating device can be used at extremely high temperatures, is not prone to dirt adhesion, and effectively prevents short circuits in the ion source caused by cathode contamination, thus preventing damage to the anode and cathode devices and avoiding malfunctions.
[0010] The cooling device includes a cooling pipe inlet pipe, with a cooling pipe installed on one side of the cooling pipe inlet pipe. The cooling pipe is located in a groove in the magnetic circuit module device, and a cooling pipe return pipe is installed on the other side of the cooling pipe. The cooling pipe inlet pipe and the cooling pipe return pipe are located on one side of the magnetic circuit module device. The cooling device can perform circulating water exchange operations, effectively controlling the temperature of the ion source body and quickly and effectively cooling the ion source body.
[0011] The gas path device includes a gas guide plate located on one side of the cooling device. The gas guide plate has a groove, and a sealing ring (made of fluororubber) is placed within the groove. An outlet hole is located inside the sealing ring. An inlet pipe is installed on one side of the gas guide plate. The sealing ring prevents gas leakage, which could lead to vacuum abnormalities.
[0012] The pressure block is equipped with an inlet pipe and a return pipe, and conductive devices are installed on the inlet pipe and the return pipe.
[0013] The electrostatic plate is made of stainless steel. Stainless steel has good thermal conductivity and a low coefficient of friction. Through electrostatic adsorption, the electrostatic plate can adsorb foreign objects (such as dust and particles) on the surface of the film, improving the surface quality of the film and reducing abnormal arcing, failure to glow, and failure to increase power caused by foreign objects (such as dust and particles). This improves the ion cleaning structure, enhances film adhesion, optimizes the performance of composite copper foil products, reduces manual wiping, and decreases the frequency of overall disassembly and maintenance.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This functional device rapidly absorbs heat from the ion source through the coolant in the cooling pipes of the cooling device, thereby reducing the temperature of the film surface and the ion source body surface. Compared with the natural air cooling method used in the prior art, it improves the cooling efficiency to a certain extent. After the coating operation is completed, it can effectively cool down the ion source and prevent burns caused by accidental contact with personnel.
[0016] 2. This functional device can adsorb foreign objects (such as dust, particles, etc.) on the surface of the membrane through electrostatic adsorption, thereby improving the surface quality of the membrane and reducing abnormalities of the ion source (arcing, failure to glow, failure to increase power) caused by foreign objects (such as dust, particles, etc.). It effectively prevents short circuits of the ion source caused by dirt or abnormalities in the cathode, thus avoiding damage to the anode and cathode devices and preventing abnormalities.
