Technical Field

[0001] The utility model relates to the field of quartz crystal resonator production, in particular to a laser curing device for conductive adhesive of quartz crystal resonator. Background Technique

[0002] A quartz crystal resonator is an electronic component used to generate oscillation signals. The manufacturing process of a quartz crystal resonator includes cutting, silver plating, dispensing, curing, testing, sealing, sealing inspection, aging, marking and encapsulation, etc.

[0003] After the quartz wafer is plated with electrodes, it is necessary to connect the electrodes to the leads on the base to achieve the conductive function. This connection should have high reliability and not fall off under long-term high-frequency vibration working conditions, and should also have a certain impact resistance. In the large-scale production of quartz crystal resonators, conductive adhesive is generally selected for connection to conduct electricity and fix the quartz wafer and the base. Therefore, the curing process of the conductive adhesive is a crucial procedure.

[0004] For the curing of the conductive adhesive of the existing quartz crystal resonator (such as: CN117767911A), usually the semi-finished products of the quartz crystal resonator with qualified dispensing are sent into the curing furnace in batches at one time for overall heating, and the curing of the conductive adhesive is realized through overall heating. However, due to the overall heating by a large curing furnace, it is easy to cause energy waste, and it is easy to cause thermal deformation and stress damage of the quartz crystal, resulting in a decline in the production quality of the resonator.

[0005] Therefore, a laser curing device for conductive adhesive of quartz crystal resonator is now developed, which can cure the conductive adhesive with laser, is energy-efficient and can improve the production quality of the resonator. Content of the Utility Model

[0006] In order to overcome the shortcomings that the curing of the conductive adhesive of the existing quartz crystal resonator by overall heating with a large curing furnace is easy to cause energy waste, and is easy to cause thermal deformation and stress damage of the quartz crystal, resulting in a decline in the production quality of the resonator, the utility model provides a laser curing device for conductive adhesive of quartz crystal resonator, which can cure the conductive adhesive with laser, is energy-efficient and can improve the production quality of the resonator.

[0007] The technical implementation scheme of the utility model is as follows:

[0011] Furthermore, there are two laser emitters, one in the front and the other in the back, on the laser curing head, which can cure two conductive glue dots simultaneously, improving the curing efficiency.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] A laser curing device for conductive adhesive of quartz crystal resonator, as Figure 1 and Figure 2 shown, includes a box body 1, a glass window 10, a side frame 2, a fixed guide rail 3, a wafer tray 4, a laser component 5 and a power mechanism 6. Side frames 2 are connected to both the left and right sides of the lower part of the box body 1. A glass window 10 is connected to the front side of the box body 1. Two fixed guide rails 3 are connected inside the box body 1. A wafer tray 4 is slidably connected between the fixed guide rails 3. A laser component 5 is connected to the rear part of the box body 1. A power mechanism 6 is also provided on the box body 1.

[0025] As Figure 2 and Figure 3As shown, the laser assembly 5 includes a main slide rail 51, a first cylinder 52, a second cylinder 53, a laser curing head 54, a camera 55, an infrared temperature sensor 56, and a laser generating device 57. The main slide rail 51 is connected to the rear part inside the box body 1. The first cylinder 52 is slidably connected to the main slide rail 51. The telescopic end of the first cylinder 52 is connected to the second cylinder 53. The telescopic end of the second cylinder 53 is connected to the laser curing head 54. The camera 55 is connected to the right side of the laser curing head 54. The infrared temperature sensor 56 is connected to the left side of the laser curing head 54. The laser generating device 57 is placed at the rear side of the box body 1. The laser emitter is connected to the laser curing head 54 through an electric wire. There are two laser emitters, front and back, on the laser curing head 54, which can cure two conductive adhesive points simultaneously, improving the curing efficiency.

[0026] As Figure 1 and Figure 4 As shown, the power mechanism 6 includes a fixed frame 61, a motor 62, and a friction belt 63. The fixed frames 61 are connected to both the left and right sides of the lower inner wall of the box body 1. The motors 62 are connected to the front sides of the fixed frames 61. The friction belt 63 is wound around the output shafts of the motors 62.

[0027] When using the present utility model, first place the box body 1 in the curing area of the conductive adhesive of the quartz crystal resonator, then start the motor 62 on the fixed frame 61 to make the friction belt 63 rotate. Through the contact and cooperation between the friction belt 63 and the wafer tray 4, the wafer tray 4 slides on the fixed guide rail 3, and the wafer tray 4 is moved to the side frame 2. Then place the resonator coated with the conductive adhesive to be cured on the wafer tray 4 on the side frame 2, and then push the side frame 2 into the inside of the box body 1. The curing process of the conductive adhesive can be observed through the glass window 10. After pushing the wafer tray 4 into the inside of the box body 1, start the motor 62 to transport the wafer tray 4 to the middle of the box body 1. Control the camera 55 to start, position the resonator to be fixed, and control the main slide rail 51, the first cylinder 52, and the second cylinder 53 to start according to the positioning position of the camera 55 to move the laser curing head 54 above the resonator to be fixed. Then start the laser generating device 57 to make the laser curing head 54 emit laser to cure the conductive adhesive. At the same time, start the infrared temperature sensor 56 to measure the temperature of the laser curing part to ensure the completion of the laser curing process. After the conductive adhesive on the resonator is cured, move the laser curing head 54 to the next resonator to be cured to continue the curing according to the positioning of the camera 55. When all the resonators on the wafer tray 4 are cured, start the motor 62 on the fixed frame 61 to make the friction belt 63 rotate, and transport the resonators on the wafer tray 4 to the side frame 2 on the other side for discharging. Thus, it can cure the conductive adhesive with laser, which is energy-efficient and can improve the production quality of the resonator.

[0028] AsFigure 1 and Figure 5 As shown in and

[0029] , it further includes a nitrogen filling mechanism 7. The nitrogen filling mechanism 7 includes a nitrogen gas chamber 71, an air pump 72, an air pipe 73, an electric push rod 74, a sleeve rod 75 and a closing door 76. The air pump 72 is connected to the upper side of the box body 1, the nitrogen gas chamber 71 is connected to the upper side of the air pump 72, the nitrogen gas chamber 71 and the box body 1 are connected by the air pipe 73. On both the left and right sides inside the box body 1, there are two electric push rods 74 connected in the front and rear. The telescopic ends of the electric push rods 74 are all connected with sleeve rods 75. On both the left and right sides of the box body 1, there are closing doors 76 rotatably connected. The sleeve rods 75 are in contact and cooperation with the adjacent closing doors 76.

[0029] When using the nitrogen filling mechanism 7 of this device, nitrogen filling protection can be carried out during laser curing. After moving the resonator to be cured into the box body 1, start the air pump 72, extract the nitrogen gas in the nitrogen gas chamber 71 into the box body 1 through the air pipe 73, and make the nitrogen gas circulate inside the box body 1. During laser curing, the nitrogen gas isolates the air, preventing the water vapor in the air from contacting and crystallizing with the conductive adhesive, thus playing a role in preventing the conductive adhesive from contacting and crystallizing with water vapor during laser curing and avoiding the reduction of the production quality of the resonator. When curing the conductive adhesive, start the electric push rod 74 to make the telescopic end of the electric push rod 74 push out, so that the sleeve rod 75 moves downward. Through the contact and cooperation between the sleeve rod 75 and the closing door 76, the closing door 76 rotates downward and closes with the box body 1, reducing the loss of nitrogen gas in the box body 1. When it is necessary to push the wafer tray 4 into or out of the box body 1, start the electric push rod 74 to make the telescopic end of the cushion push rod move upward, so that the sleeve rod 75 moves upward. Through the contact and cooperation between the closing door 76 and the sleeve rod 75, the closing door 76 rotates and opens, and then the wafer tray 4 is moved into and out of the box body 1.
