Description

Technical Field

[0001] The present invention relates to an auxiliary device for sealing and soldering quartz crystals, and in particular to an anti-sticking device for sealing and soldering quartz crystals in a high-vacuum environment. Background Art

[0002] Quartz crystal high-vacuum sealing and soldering is generally completed by a parallel seam welder. It welds and seals the cover plate and the base frame by resistance welding, isolating the quartz wafer in the base from the outside gas, thereby obtaining better product characteristics. The specific operation process is as follows: In a high-vacuum environment, two motor wheels are in contact with the crystal metal cover plate to form a closed circuit. Since there is a contact resistance between the electrode wheel and the cover plate and between the cover plate and the base frame, according to the energy formula (Q = I 2 Rt), a large amount of heat is generated at these two contact resistances by the welding current, causing the area between the cover plate and the base frame to locally form a molten state, and after solidification, solder joints are formed. During the above welding process, the sealing and soldering power supply continuously emits pulsed current, intermittently energizing between the electrodes under a certain pressure. While the welding electrodes are moving, through the rotation of the electrode wheels, a series of overlapping solder joints are formed between the cover plate and the base frame, thereby forming a continuous weld seam and ensuring the airtight encapsulation of the quartz wafer.

[0003] Currently, with the development trend of miniaturization of quartz crystal products, the mass of a single product is getting smaller and smaller. The smaller the mass of the product, the smaller the generated gravity. After welding is completed, the molten material of the cover plate and the base is extremely easy to adhere to the electrodes, resulting in the "sticking material" phenomenon; at the same time, the heat generated by high-vacuum environment sealing and soldering is not easy to dissipate, and the accumulation of heat will be relatively serious, resulting in a relatively long molten state time at the welding point, making it easier to cause the "sticking material" problem; in addition, the high efficiency of production equipment requires the equipment to process more products in as short a time as possible, resulting in the accumulation of heat and making the "sticking material" situation more and more serious. After the "sticking material" situation occurs, the following two situations may occur: One is that after the electrode wheel "sticks material" and continues to seal and solder the next workpiece, the current passes through both the adhered workpiece and the workpiece being sealed and soldered at the same time, resulting in insufficient power applied to the workpiece being sealed and soldered, causing air leakage due to insecure welding; the other is that after the product adheres to the electrode wheel, it will randomly fall near the sealed and soldered product, or even fall on the next row of workpieces to be sealed and soldered. In this way, when sealing and soldering the next row of workpieces, the electrode wheel is lifted up, resulting in poor contact and arcing. After arcing, it is extremely easy to cause pits on the surface of the electrode wheel, resulting in air leakage of the products sealed and soldered through the pits subsequently, causing serious quality accidents. Summary of the Invention

[0004] The present invention provides an anti-sticking device for quartz crystal sealing. By switching the energized and de-energized states of the electromagnetic coil, an intermittent driving force is provided for the anti-sticking actuator under the magnetic force of the electromagnet, causing the pressing piece installed at one end of the anti-sticking actuator to move up and down. Thus, when the electrode moves to the next workpiece position, the completed-sealed quartz crystal is pressed down, promoting the separation from the workpiece during the lifting of the electrode wheel, achieving the purpose of avoiding the "sticking material" problem and improving the sealing quality of the quartz crystal.

[0037] See Figure 5 、 Figure 6 For the anti-sticking device for quartz crystal sealing welding according to the present invention, a rotating arm reset limiting component 3-10 is further provided in the anti-sticking execution mechanism 3 thereof; the rotating arm reset limiting component is installed on the fixed component 2, located between the tension spring 3-5 and the rotating arm reset buffer component, and is arranged opposite to the upper end surface of the rotating arm 3-1.

[0038] See Figure 5 、 Figure 6 、 Figure 8 For the anti-sticking device for quartz crystal sealing welding according to the present invention, a rotating arm limiting component is further provided in the anti-sticking execution mechanism 3 thereof.

[0039] See Figure 9 、 Figure 10, the anti-sticking device for quartz crystal sealing of the present invention has the following working process: When the sealing equipment seals the quartz crystal workpiece, the lower end of the pressing piece 4 is hidden inside the edge of the electrode wheel 5; after the electrode wheel 5 completes the sealing of one workpiece, it performs a rolling-back action, so that the pressing piece 4 is directly above the workpiece; the electromagnetic coil in the electromagnet assembly 1 is energized, and the coupling 1-1 is driven by the magnetic force of the electromagnet to apply a downward pressure to the roller assembly 3-4, so that the rotating arm 3-1 in the anti-sticking actuator 3 rotates clockwise, and the pressing piece 4 installed at the rear end of the anti-sticking actuator 3 moves downward accordingly, and a downward pressure is applied to the sealed quartz crystal workpiece through the pressing piece 4; at this time, the sealing equipment controls the electrode wheel 5 to lift, so that the workpiece is separated from the electrode wheel 5; then the electromagnetic coil in the electromagnet assembly 1 is powered off, and the magnetic force of the electromagnet is released, and the coupling 1-1 and the roller assembly 3-4 no longer apply pressure to the rotating arm 3-1. At this time, under the elastic force of the tension spring 3-5, the rotating arm 3-1 rotates counterclockwise to reset, and the lower end of the pressing piece 4 moves upward to reset inside the edge of the electrode wheel 5, entering the next working cycle.
