Description

Technical Field

[0001] This utility model relates to the field of vacuum coating and cleaning technology, and in particular to a novel high-efficiency vacuum coating and cleaning device. Background Technology

[0002] Vacuum coating refers to a method of heating metal or non-metal materials under high vacuum conditions, causing them to evaporate and condense onto the surface of the workpiece (metal, semiconductor, or insulator) to form a thin film. Coated hardware workpieces need to be cleaned, mainly to remove pollutants such as chemicals, particles, or fingerprints that may remain during the coating process. If these residues are not removed in time, they will affect the performance of the coating layer, such as adhesion and corrosion resistance, and may even cause the coating layer to peel off or produce defects.

[0003] Existing cleaning devices for vacuum coating of hardware occupy a large space and have low space utilization in the cleaning chamber. At the same time, the vibration radiation space generated by the ultrasonic generator installed on one side is small, resulting in poor cleaning efficiency for coated hardware workpieces in the cleaning chamber. It is necessary to increase the cleaning time to achieve the required cleanliness. This cleaning method is inefficient, delays the factory production schedule, and cannot meet the corresponding production needs. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a novel high-efficiency vacuum coating cleaning device, comprising a cleaning chamber 1, the top of which is provided with a receiving cavity 10 for storing coated metal workpieces. A storage section is suspended within the receiving cavity 10, including a tube 61 perpendicular to the bottom of the receiving cavity 10. A support plate 62 for supporting the coated metal workpieces is welded to the outer diameter of the tube 61. An upwardly protruding anti-fall plate 64 is provided on the top edge of the support plate 62. A cover plate 3 is spirally engaged with the top of the tube 61. An ultrasonic vibrating rod 5 is arranged in a circular array at the bottom of the cover plate 3 corresponding to the tube 61. An electric heater 4 is provided at the inner diameter of the tube 61. A water inlet electric control valve 211 is located on the upper left side of the cleaning chamber 1, and a drain electric control valve 212 is located on the lower right side of the cleaning chamber 1. The support plate 62 facilitates the placement of the coated metal workpieces, and the electric heater 4 on the inner diameter of the tube 61 increases the space utilization of the receiving cavity 10. The four ultrasonic vibrating rods 5 in the ring array facilitate improved cleaning efficiency and reduced cleaning time. The water inlet solenoid valve 211 and the drain solenoid valve 212 facilitate control of water inlet and outlet, increasing ease of use. The bottom shape of the cover plate 3 is the same as the horizontal cross-section of the receiving cavity 10. Positioning blocks 31 are provided on the left and right sides of the cover plate 3 respectively. The top of the side wall of the cleaning chamber 1 is provided with a downwardly recessed fixing groove 12 corresponding to the position of the positioning block 31. The cover plate 3 can effectively shield the receiving cavity 10, improve the heating efficiency of the electric heater 4 in the tube 61, and shorten the cleaning time. The bottom of the positioning block 31 is parallel to the bottom of the cleaning chamber 1. The side of the fixing groove 12 that fits against the bottom of the positioning block 31 is parallel to the bottom of the positioning block 31. By keeping the bottom of the positioning block 31 parallel to the bottom of the cleaning chamber 1, the cover plate 3 is prevented from rotating in the receiving cavity 10, increasing the stability of the cover plate 3 and reducing the possibility of the ultrasonic vibrating rods 5 being damaged by impact.

[0021] Please see Figure 2 - Figure 5In this embodiment, four support plates 62 are provided at the outer diameter of the tube 61. The four support plates 62 are linearly arrayed along the axis of the tube 61. The side wall of the tube 61 has a through hole 611, and the top of the support plate 62 has a through hole 621. By setting four support plates 62, one support plate 62 is divided into four placement areas, increasing the number of coated hardware workpieces that can be accommodated, thereby improving cleaning efficiency. At the outer diameter of the tube 61, a baffle 63 is arranged in a ring at the top of the support plate 62. The side wall of the baffle 63 has a hole 631. The flow of water and air bubbles in the receiving cavity 10 is increased through the holes 611, 621, and 631. The air bubbles are generated by the vibration of the ultrasonic vibrator 5. The cover plate 3 has pressure relief chamfers 32 at the four corners. The cover plate 3 has a placement port 35 at the position corresponding to the tube 61. The diameter of the placement port 35 is the same as the inner diameter of the tube 61. The electric heater 4 includes an electric heating rod 41 that can pass through the placement port 35. The placement port 35 allows the electric heater 4 to be hung. The electric heater 4 has the same structural principle as the "hot water heater". The housing cavity 10 is equipped with a temperature sensing component. When a certain temperature is reached, the control device cuts off the power to the electric heater 4. The placement port 35 here acts as the mouth of a hot water bottle to support the "hot water heater". The pressure relief chamfer 32 facilitates the discharge of gas in the housing cavity 10. The side wall of the cleaning box 1 is welded with a support plate 11. The top of the support plate 11 is provided with a countersunk hole 111. The top of the cover plate 3 is provided with handles 33 on the left and right sides corresponding to the placement port 35. The top of the cover plate 3 is provided with a wire hole 34 to avoid the cable of the ultrasonic vibrator 5. The cooperation between the support plate 11 and the countersunk hole 111 can increase the stability of the device on the workbench. The handles 33 can lift the storage part upwards, which is convenient for taking out or placing coated hardware workpieces on the support plate 62. The handles 33 can be used for hand gripping and lifting or for robotic arm grabbing.

[0022] During operation, the worker uses their bare hands or a robotic arm to grasp the handle 33 of the cover plate 3, lifting the cover plate 3 along with the storage section. Then, the coated metal workpiece is placed on top of the support plate 62. After the coated metal workpiece is placed in the storage section, the cover plate 3 is moved downwards, and the positioning block 31 is engaged in the fixing groove 12. The drain control valve 212 is closed, and the water inlet control valve 211 is opened to fill the receiving cavity 10 with water. The water can be pure water or a cleaning solution mixed with cleaning agents. The formula and ratio of the cleaning agents are known to those skilled in the art. When a certain amount of water is filled into the receiving cavity 10, and the amount of water is suitable for immersing the coated metal workpiece, the water inlet control valve 211 is closed. After the electric heater 4 heats the water in the receiving cavity 10 to a certain temperature, the ultrasonic vibrator 5 is energized to clean the coated metal workpiece in the water. The cleaning principle of the ultrasonic vibrator 5, the heating principle of the electric heater 4, and the water level sensor installed in the receiving cavity 10 are all existing technologies.

[0023] Through the above steps, the support plate 62 facilitates the placement of coated metal workpieces, the inner diameter of the tube 61 is equipped with an electric heater 4 to increase the space utilization of the receiving cavity 10, the four ultrasonic vibrating rods 5 in the ring array facilitate the improvement of cleaning efficiency and the reduction of cleaning time, and the water inlet electric control valve 211 and the drain electric control valve 212 facilitate the control of water inlet and drainage and increase ease of use, so as to solve the problems of large footprint, low space utilization in the cleaning chamber, and poor cleaning efficiency of coated metal workpieces in the cleaning chamber in the existing metal vacuum coating cleaning device.
