[0032] Example 1

[0033] See also Figure 1-5 The utility model provides a technical solution: a closed crystal oscillator automatic welding device, comprising:

[0034] Protective cover 1;

[0035] The workbench assembly 2 includes a support seat 21, a rotary drive member 22 and a base 23. The support seat 21 is fixedly mounted on the output end of the rotary drive member 22. The base 23 is slidably connected to the support seat 21. The product 9 to be welded is placed on the base 23.

[0036] The transverse moving assembly 3 includes a frame 31, a transverse moving driving member 32 and a driving cylinder 33. The transverse moving driving member 32 is fixedly mounted on the frame 31, and the driving cylinder 33 is fixedly mounted on a moving seat of the transverse moving driving member 32. The transverse moving driving member 32 can specifically be a screw drive;

[0037] The welding head assembly 4 is fixedly mounted on the output end of the driving cylinder 33 . The welding head assembly 4 comprises two circular welding heads 41 arranged in parallel. The circular welding heads 41 are rotatably mounted on the welding head assembly 4 .

[0038] The protective cover 1 comprises a front cover plate 11 and a cover body 12 , wherein the front cover plate 11 is hinged to the cover body 12 , so as to facilitate opening the protective cover 1 and replacing the product 9 to be welded.

[0039] The front cover plate 11 is a transparent glass plate or a transparent acrylic plate, which is convenient for observing the internal welding process.

[0040] A guide 42 is provided on the welding head assembly 4, and an air pipe 43 is passed through the guide 42. The air pipe 43 is connected to a negative pressure generating device. The negative pressure generating device generates negative pressure in the air pipe 43 to suck the waste gas generated during welding. The guide 42 positions the end of the air pipe 43 between the two circular welding heads 41 to improve the suction effect.

[0041] The base 23 includes a base body 231, a lifting member 232 and a supporting plate 233. The base body 231 is slidably connected to the support base 21, the lifting member 232 is fixedly mounted on the base body 231, and the supporting plate 233 is fixedly mounted on the output end of the lifting member 232. The product 9 to be welded is placed on the supporting plate 233, and the lifting member 232 can specifically adopt an electric push rod to lift up and down and adjust the height of the supporting plate 233 to ensure the welding quality after the welding head assembly 4 is lowered.

[0042] The rotary drive member 22 is a rotary cylinder, which is convenient for driving the support seat 21 and the base 23 to rotate smoothly as a whole.

[0043] Working principle: The sealing of the product 9 to be welded is mainly to seal a single CAP (cap) arranged in an array on the assembled base to make the product sealed and maintain the durability of the product.

[0044] When the product 9 to be welded is placed on the base 23 for welding, the two circular welding heads 41 of the welding head assembly 4 simultaneously contact one opposite side of a CAP, and the sliding of the base 23 drives the product 9 to be welded to move along the Y-axis to achieve welding; after welding one CAP, the welding head assembly 4 moves upward by driving the cylinder 33, and the workbench assembly 2 drives the product 9 to be welded to move along the Y-axis through the sliding of the base 23, and the welding head assembly 4 moves downward again for welding. After welding one column of CAPs in turn, the welding head assembly 4 moves along the X-axis through the transverse driving member 32 to weld another column of CAPs, thereby completing the welding of one opposite side of all CAPs.

[0045] Afterwards, the workbench assembly 2 drives the base 23 to rotate 90 degrees through the rotating driving member 22, and repeats the above welding process, so that the other opposite sides of all CAPs on the product 9 to be welded are welded.

[0046] The two circular welding heads 41 of the welding head assembly 4 simultaneously contact an opposite side of a welding cover of the product 9 to be welded, and the product 9 to be welded is translated and rotated along the Y axis through the workbench assembly 2, and the welding head assembly moves along the X axis of the traverse drive 32, so as to effectively weld all welding points on the product 9 to be welded, thereby improving welding efficiency. The product 9 to be welded is welded inside the protective cover 1, and the worker is separated from the welding head, thereby improving the safety of the welding process.
