Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of hemispherical resonant gyroscope packaging, and in particular relates to a batch laser welding packaging clamping device and a packaging method for hemispherical resonant gyroscopes. Background Art
[0002] The hemispherical resonant gyroscope is a new type of vibrating gyroscope that uses the standing wave precession effect of the hemispherical resonator to sense the rotation of the base. It has the unique advantages of high precision, low cost, small size and high reliability, and is currently a hot spot in the research and application of inertial technology. The head structure of the hemispherical resonant gyroscope mainly includes the hemispherical resonator, electrodes and the overall shell, and its vibration characteristics have the characteristics of a high quality factor (Q value). However, when the hemispherical resonant gyroscope is packaged, air damping is the most important damping factor for the vibration of the resonator. When the vacuum degree is insufficient, the damping is too large, which seriously affects the vibration performance of the hemispherical resonator and even makes it impossible to start vibration. Therefore, low leakage rate packaging is the basic requirement for maintaining a high vacuum inside the gyroscope to enable it to work normally. A large number of studies on vacuum packaging devices and methods have been carried out, but the laser welding packaging method for the hemispherical resonant gyroscope can only be manually welded individually, and there is no batch packaging solution.

The gyroscope packaging is mainly to laser weld the housing 1 and the gyroscope base 2, and the welding surface is a gap 3. The welding method is to first press the welding part of the parts to ensure that there is no gap, rotate the parts 360 degrees and perform laser spot welding at several positions. At this time, the gyroscope housing 1 has been connected to the base 2, and the pressing tooling can be removed. Finally, the parts are rotated 360 degrees for continuous welding.
[0050] To this end, the batch laser welding packaging method of the hemispherical resonant gyroscope of the present invention specifically includes the following steps:
[0051] (1) Install a gyro base 2 on the flange fixture 5, fix the gyro flange fixture 5 to the first mounting bearing 6 through the chuck 9, and fix the first mounting bearing 6 on the gyro welding station of the mounting turntable 7;
[0052] Repeat the above operation to fix multiple gyro bases 2;

[0055] (4) driving the first mounting bearing 6 to rotate the welded gyroscope along its circumference for one circle, and spot welding is performed on the welded gyroscope at multiple positions. When the gyroscope rotates, the second clamping bearing 13 is driven to rotate to ensure that the clamping bracket 10 always presses the gyroscope housing 1;
[0056] (5) After the spot welding of the current gyro is completed, the second mounting bearing 8 is driven to rotate, driving the mounting turntable 7 to revolve, driving the pressing turntable 14 to rotate synchronously, and another gyro to be welded is replaced to reach the welding position, and the operation of step (4) is performed;
[0057] (6) Repeat step (5) to complete spot welding of all gyroscopes on the mounting turntable 7;
[0058] (7) Remove the gyro clamping device, drive the first mounting bearing 6, and make the gyro at the welding position rotate one circle along its circumference, and continuously laser weld the current gyro;
[0059] (8) driving the second mounting bearing 8 to rotate, driving the mounting turntable 7 to revolve, replacing another gyroscope to be welded to the welding position, and performing continuous laser welding on the gyroscope;

[0061] As a specific embodiment of the present invention, in step (1), the gyro base 2 can be mounted on the flange fixture 5 by screws.
[0062] In step (3), the gyroscope to be welded is moved to the position below the laser by rotating the mounting turntable 7, and the welding position is aligned with the focus of the laser.
[0063] In step (4), the gyroscope to be welded is rotated one circle along its circumference, and spot welding is performed on the gyroscope at four positions, corresponding to 0 degrees, 180 degrees, 270 degrees and 90 degrees.
[0064] In steps (3), (4), (5), (7) and (8), the corresponding mounting bearings can be driven to rotate by a motor.
[0065] The batch laser welding packaging method of the hemispherical resonant gyroscope of the present invention controls the rotation and revolution of the gyroscope through a program to achieve spot welding and continuous welding of the gyroscope, avoids manual single operation, reduces labor costs, and improves packaging efficiency.
[0066] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0067] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
