Description

Technical Field

[0001] The present invention relates to the technical field of resonator packaging, and specifically to a packaging method and device for a small quartz crystal resonator. Background Art

[0002] A quartz crystal resonator is an electronic component that works based on the piezoelectric effect of a quartz crystal. It is mainly used to generate and maintain a stable frequency, has excellent frequency stability, and is widely used in electronic devices such as clocks, computers, mobile phones, and other communication devices.

[0003] Currently, during the manufacturing process of quartz crystal resonators, the base and the metal lid need to be welded and sealed by the electrode discharge of a semi-automatic sealing machine to ensure its electrical characteristics. Since the packaging is carried out by the circular electrodes of the electrode bracket pressing on the edge of the metal lid and using current for packaging, the electrode bracket and the electrode wheel need to be maintained regularly. After the electrode wheel is replaced, there is a risk of air leakage, which poses a certain safety hazard. Moreover, when the electrode wheel and the metal lid are being packaged, if the current is too large, they are likely to stick together, resulting in the explosion of the wheel and batch abnormalities. In view of the above problems, the inventor proposes a packaging method and device for a small quartz crystal resonator to solve the above problems. Summary of the Invention

[0053] A packaging method used in a small quartz crystal resonator packaging device includes the following steps:

[0054] Step 1: The fixture is driven by the transport roller 116 to pass through the vacuum front chamber 102, the preheating chamber 103, the heating chamber 104, the packaging chamber 105 and the cooling chamber 106 in sequence and move to the unloading table 201. At this time, the temperatures (275°C ± 5°C) and vacuum degrees (below 5*10-3 Pa) of the preheating chamber 103, the heating chamber 104 and the packaging chamber 105;

[0055] Step 2: When the fixture passes through the preheating chamber 103, the heating chamber 104 and the packaging chamber 105, the resonator is preheated and packaged by the upper heating plate 113 and the lower heating plate 122. And when packaging, the resonator is lifted by the ejector pin to avoid adhesion.

[0056] Step 3: The packaged resonator is unloaded by the suction cup 205.

[0057] Step 4: The fixture is cleaned and dried by the brush roller 404 and the hot air blower 403.

[0058] Working principle: First, open the electric control door between the vacuum front chamber 102 and the preheating chamber 103. Then, turn on the second motor 121 outside the vacuum front chamber 102 to drive the mounting rod 119 to rotate. The rotation of the mounting rod 119 drives the second bevel gear 120 to rotate. The rotation of the second bevel gear 120 drives the first bevel gear 118 to rotate. The rotation of the first bevel gear 118 drives the rotating shaft 117 to rotate. The rotation of the rotating shaft 117 drives the conveying roller 116 to rotate. The reverse rotation of the conveying rollers 116 on both sides drives the fixture to move, so that the fixture moves to the heating chamber 104. When the fixture moves into the heating chamber 104, turn on the second motor 121 outside the heating chamber 104 to drive the conveying roller 116 to rotate, so that the fixture moves to the lower heating plate 122 on the side close to the vacuum front chamber 102. At this time, close the electric control door between the vacuum front chamber 102 and the preheating chamber 103. Turn on the first motor 111 to drive the rotating rod 110. The rotation of the rotating rod 110 drives the first cam 112 to rotate. The rotation of the first cam 112 drives the upper heating plate 113 and the lower heating plate 122 to move, preheating the resonator. At the same time, the movement of the lower heating plate 122 drives the transmission rod 126 to move. The movement of the transmission rod 126 drives the driving bar 128 to move. At this time, due to the block of the fixed bar 129, the driving bar 128 is pushed to rotate. The rotation of the driving bar 128 drives the transmission rod 126 to rotate. The rotation of the transmission rod 126 drives the rotating rod 125 to rotate. The rotation of the rotating rod 125 drives the limiting rod 124 to rotate. The fixture is positioned by the contact between the limiting rod 124 and the fixture;

[0059] Secondly, through the above steps, the fixture passes through the heating chamber 104, the encapsulation chamber 105 and the cooling chamber 106 in sequence and moves to the discharging platform 201. The resonator is preheated, encapsulated and cooled by the heating chamber 104, the encapsulation chamber 105 and the cooling chamber 106 in sequence. At this time, when the fixture enters the encapsulation chamber 105 for encapsulation, since there are ejector pins on the lower heating plate 122 in the encapsulation chamber 105, during encapsulation, the resonator is lifted by the ejector pins to prevent the resonator from adhering to the inside of the fixture during encapsulation;

[0060] Then, the fixture is positioned by the positioning mechanism. After the positioning is completed, the third motor 307 is turned on to drive the first vertical rod 306 to rotate. The rotation of the first vertical rod 306 drives the rotation of the second toothless gear 315 and the first toothless gear 308. At this time, when the first vertical rod 306 rotates the first one-sixth of a circle, when the second toothless gear 315 meshes with the second gear 317, it drives the second gear 317 to rotate. The rotation of the second gear 317 drives the rotation of the third vertical rod 316. The rotation of the third vertical rod 316 drives the rotation of the drive column 302. The rotation of the drive column 302 drives the rotation of the rotating column 202. The rotation of the rotating column 202 drives the rotation of the rotating plate 203. The rotation of the rotating plate 203 drives the movement of the suction cup 205, so that the suction cup 205 moves to directly above the fixture.

[0061] At this time, when the first vertical rod 306 rotates the second one-sixth of a circle, when the first toothless gear 308 meshes with the first gear 311, it drives the first gear 311 to rotate. The rotation of the first gear 311 drives the rotation of the second vertical rod 310. The rotation of the second vertical rod 310 drives the rotation of the third bevel gear 312. The rotation of the third bevel gear 312 drives the rotation of the fourth bevel gear 314. The rotation of the fourth bevel gear 314 drives the rotation of the second cross bar 313. The rotation of the second cross bar 313 drives the rotation of the first cross bar 303. The rotation of the first cross bar 303 drives the rotation of the second cam 304. The rotation of the second cam 304 drives the movement of the rotating column 202. At this time, the rotating column 202 moves downward, so that the suction cup 205 moves downward to contact the upper surface of the fixture. The air pump 204 is turned on to limit the encapsulated resonator through the suction cup 205. Then, the continuous rotation of the first vertical rod 306 drives the suction cup 205 to move upward, return to the original position, move downward, and move upward in sequence, completing the unloading of the encapsulated resonator.

[0062] Finally, the first electric cylinder 207 is turned on to drive the push bar 208 to move, thereby driving the fixture to move to the cleaning table 401. The fourth motor 409 is turned on to drive the third cross bar 406 to rotate. The rotation of the third cross bar 406 drives the rotation of the transport wheel 407. The rotation of the transport wheel 407 drives the movement of the conveyor belt 408. The movement of the conveyor belt 408 drives the movement of the push frame 410. The movement of the push frame 410 drives the movement of the fixture, so that the fixture passes through the cleaning table 401. At the same time, the rotation of the fourth motor 409 drives the rotation of the brush roller 404. The rotation of the brush roller 404 cleans the fixture, and the hot air blower 403 dries the cleaned fixture, enabling the fixture to be recycled.
