Description

Technical Field

[0002] In the manufacturing process of quartz crystal resonators, coating is a crucial step. Coating not only protects the surface of the crystal from environmental corrosion, but also optimizes the performance of the crystal, such as frequency stability and temperature stability, by adjusting the material and thickness of the coating layer. However, existing coating processes often do not clean the surface of the crystal to be coated thoroughly before coating, and there are problems with residual contaminants such as dust and particles. These contaminants can become defect sources during the coating process, causing defects such as pinholes, cracks, and poor adhesion in the coating layer, seriously affecting the quality of the coating and the performance of the crystal. Traditional cleaning methods, such as manual wiping or blowing with compressed air, are not only inefficient but also difficult to ensure consistent cleaning results.

[0003] Therefore, how to provide a coating device that can effectively clean the surface of the crystal oscillator to be coated before coating while ensuring the coating quality and production efficiency has become a technical problem that needs to be solved urgently in the current quartz crystal resonator manufacturing field.

[0022] The coating surface dust removal mechanism includes a frame Ⅰ1, which is formed into a roughly square frame structure. A mounting platform Ⅰ2 is fixedly installed in the middle of the frame Ⅰ1, and the mounting platform Ⅰ2 is formed into a roughly square plate-shaped structure. An air duct 3 is fixedly installed on the top of the frame Ⅰ1. The air duct 3 is horizontally arranged. The space between the air duct 3 and the mounting platform Ⅰ2 forms a coating surface purge space. A plurality of air blowing heads 4 for purge the coating surface purge space are installed at the bottom of the air duct 3. The air blowing head 4 is a vertical pipe structure with an opening at the bottom end. A fan 5 is installed on the top surface of the mounting platform Ⅰ2. The fan 5 is a conventional technology and its specifications and models can be selected according to the use requirements. The air outlet of the fan 5 is connected to the air duct 3 through a pipe.

[0023] The coating mechanism includes a frame II 6, which is formed into a roughly square frame structure. A mounting platform II 7 is fixedly installed in the middle of the frame II 6, and the mounting platform II 7 is formed into a roughly square plate-shaped structure. A top plate 8 is fixedly installed on the top of the frame II 6, and the top plate 8 is formed into a roughly square plate-shaped structure. A horizontal telescopic power mechanism 9 is fixedly installed at the bottom of the mounting platform II 7. The horizontal telescopic power mechanism 9 and the vertical telescopic power mechanism 10 described below can both adopt an electric cylinder or a pneumatic cylinder. A slide rail 11 is fixedly installed on the top of the mounting platform II 7. The top plate 8 is provided with a slider 12 for use with each other. The slider 12 is formed into a roughly square plate-shaped structure. A carrying plate 13 is fixedly installed on the top of the slider 12. The carrying plate 13 is formed into a roughly square plate-shaped structure. A plurality of placement grooves 14 for carrying quartz crystal resonators are provided on the top surface of the carrying plate 13. The placement grooves 14 are formed into a roughly square groove-shaped structure. The depth of the grooves can be selected according to the use requirements. A vertical telescopic power mechanism 10 is fixedly installed on the bottom surface of the top plate 8, and a spraying mechanism is provided on the telescopic end of the vertical telescopic power mechanism 10;

[0024] The slider 12 and the slide rail 11 are directly opposite to the coating surface purge space, the telescopic end of the transverse telescopic power mechanism 9 is fixedly connected to the side of the slider 12, and the carrier plate 13 is pushed / pushed out of the coating surface purge space by the transverse telescopic power mechanism 9;

[0025] The spraying mechanism includes an isolation cover 15 fixed on the telescopic end of the vertical telescopic power mechanism 10. The isolation cover 15 is formed into a roughly arc-shaped cover structure. The internal space of the isolation cover 15 forms a coating space. A paint supply box 16 is fixedly provided on the top surface of the isolation cover 15. The paint supply box 16 is formed into a roughly square box structure. The space inside it forms a space for filling paint. A pump for supplying paint can be configured inside it (not shown in the figure). A number of coating spray guns 17 are vertically fixedly installed on the bottom surface of the isolation cover 15. The coating spray guns 17 are existing technologies. Their specifications and models can be selected according to usage requirements. The feed port of the coating spray gun 17 is connected to the inside of the paint supply box 16 through a pipeline. The installation spacing and number of the coating spray guns 17 are set in a one-to-one correspondence with the placement slots 14 on the carrier plate 13.

[0026] In order to increase the contact stability between the isolation cover 15 and the slider 12, a slot 18 is provided on the top edge of the carrier plate 13 for the bottom edge of the isolation cover 15 to be inserted. The slot 18 is formed into a roughly square groove (such as Figure 3 ).

[0027] The use process of the quartz crystal resonator coating device is as follows:

[0028] (1) Preparation stage: First, ensure that the paint supply box 16 is filled with an appropriate amount of paint, and check the working status of the pump to ensure that the paint can be smoothly supplied to the coating spray gun 17. Check the connection and operating status of the air duct 3, fan 5, horizontal telescopic power mechanism 9, vertical telescopic power mechanism 10 and coating spray gun 17 to ensure that they are correct;

[0029] (2) Dust removal stage: The quartz crystal resonator to be coated is placed in the placement slot 14 of the carrier plate 13, and the telescopic end of the transverse telescopic power mechanism 9 is extended by an external power supply, so that the carrier plate 13 is located below the air blowing head 4, and the fan 5 is started to blow air to the coating surface through the air duct 3 and the air blowing head 4 to remove dust from the coating surface of the quartz crystal resonator to ensure that the coating surface is clean and free of impurities. After the dust removal is completed, the transverse telescopic power mechanism 9 is started and retracted again, causing the carrier plate 13 and the slider 12 to move along the slide rail 11, so that the carrier plate 13 and the quartz crystal resonator enter the coating position (the position below the isolation cover 15) and prepare for coating;

[0030] (3) Coating stage: When the carrier plate 13 moves to the coating position, the vertical telescopic power mechanism 10 starts, driving the isolation cover 15 to descend, so that the bottom edge of the isolation cover 15 is inserted into the slot 18 on the top surface of the carrier plate 13, thereby increasing the contact stability between the isolation cover 15 and the slider 12 and forming a coating space. The coating spray gun 17 starts working and sprays the paint from the paint supply box 16 to evenly coat the coating surface of the quartz crystal resonator. The spray speed, spray amount and spray time and other parameters of the coating spray gun 17 can be adjusted according to the coating requirements and the characteristics of the paint.

[0031] (4) Completion and removal stage: After the coating is completed, the vertical telescopic power mechanism 10 drives the isolation cover 15 to rise and separate from the carrier plate 13. The horizontal telescopic power mechanism 9 is started again to push the carrier plate 13 and the coated quartz crystal resonator back to the initial position, and the coated quartz crystal resonator is taken out.
