[0034] The embodiment of the present invention discloses a laser vacuum sealing machine, which includes a machine body 1 , a processing station and a laser welding mechanism 6 .

[0035] The machine body 1 is used to set a processing station and carry a laser welding mechanism 6. The machine body 1 is provided with a plurality of processing stations. A vacuum welding fixture and a moving mechanism 5 are provided in the processing station. The welding fixture includes a vacuum fixture 3, a product fixture 2 and a vacuum device 4. Figure 4As shown, the product jig 2 is detachably and sealably connected to the bottom of the vacuum jig 3. The product jig 2 is used to seal and cooperate with the bottom of the product 7 to be welded in the circumferential direction. The product jig 2 is made of transparent material. The vacuum jig 3 is connected to the vacuum pump 4. The moving mechanism 5 is used to carry the product 7 to be welded and deliver the product 7 to be welded to the product jig 2. The laser welding mechanism 6 is arranged on the body 1, and is used to weld the bottom seam of the product 7 to be welded through the product jig 2.

[0036] Compared with the prior art, the laser vacuum sealing machine provided in the embodiment of the present application has multiple processing stations, and the product fixture 2 and the vacuum fixture 3 on each processing station are detachably connected. In the actual production process, the adapted product fixture 2 can be replaced according to different product requirements, so that the laser vacuum sealing machine can produce multiple categories of products at the same time, thereby improving work efficiency.

[0037] In one embodiment of the present application, the moving mechanism 5 is a two-dimensional or three-dimensional moving mechanism 5, that is, it at least includes a horizontal moving component 501 and a vertical moving component 502, wherein the horizontal moving component 501 is used to drive the product carrier carrying the product 7 to be welded to move in the horizontal direction, and the vertical moving component 502 is used to drive the horizontal moving component 501 to move vertically.

[0038] Specifically, in the above embodiment, the horizontal moving assembly 501 includes a first transverse mechanism, which includes a first transverse base and a first transverse driving device. The first transverse driving device is used to drive the first transverse base to reciprocate along a first direction on a horizontal plane, and the product carrier is arranged on the first transverse base.

[0039] On the basis of the above embodiment, the horizontal moving component 501 also includes a second transverse mechanism, which includes a second transverse base and a second transverse driving device. The second transverse driving device is used to drive the second transverse base to reciprocate along the second direction of the horizontal plane. The first transverse driving device is arranged on the second transverse base, and the first direction intersects with the second direction. In this way, by enabling the horizontal moving component 501 to reciprocate in two directions in the horizontal plane, a three-dimensional moving mechanism 5 can be formed in conjunction with the above-mentioned vertical moving component 502, so that the bottom of the product 7 to be welded can be more accurately inserted into the product fixture 2.

[0040] The vertical moving assembly 502 includes a vertical base and a vertical driving device. The vertical driving device is used to drive the vertical base to reciprocate in the vertical direction. The second lateral driving device is disposed on the vertical base.

[0041] It should be noted that the above-mentioned first lateral drive device, second lateral drive device and vertical drive device are used for linear reciprocating movement, so they can be piston cylinders, such as air cylinders or hydraulic cylinders, or they can also be linear motors, or they can include rotary motors and transmission mechanisms. The transmission mechanism is used to convert the rotation of the rotary motor into linear reciprocating movement. The transmission mechanism can be a gear rack mechanism, a synchronous belt mechanism, a cam connecting rod mechanism, etc., which is not limited here.

[0042] Of course, the moving mechanism 5 is not limited to the above structure. In other embodiments of the present application, the moving mechanism 5 can also be a multi-degree-of-freedom robotic arm.

Figure 5 and Figure 6 Not shown, the exhaust valve 408 is used to exhaust the system after welding is completed, and the resistance vacuum gauge 409 is used to detect the vacuum degree in the pipeline to control the molecular pump 401, the front stage pump 402 and the pre-pump 403 to operate according to the predetermined instructions.

[0045] When the bottom of the product to be welded 7 enters the product fixture 2 and moves into position, the front pump 402 starts, the first vacuum baffle valve 404 opens, and after the vacuum degree reaches the set value, the molecular pump 401 starts; at the same time, the pre-pump 403 starts, the second vacuum baffle valve 405 opens, and the low vacuum valve 407 opens. When the low vacuum degree reaches the set value, the low vacuum valve 407 closes and the high vacuum valve 406 opens.

[0046] After welding is completed, the high vacuum valve 406 is closed, the exhaust valve 408 is opened to complete the inflation, and the moving mechanism 5 is actuated to remove the welded product from the product fixture 2 .

The image acquisition device 601 can acquire welding position images before and after welding. The controller can determine the welding position and shape according to the pre-welding image acquired by the image acquisition device 601, thereby generating a welding route. In addition, the controller can acquire the welding position image through the image acquisition device 601 during the welding process, and determine whether the welding is qualified, thereby promptly warning the production personnel, thereby improving production efficiency.

[0048] like Figure 1 As shown, in one embodiment of the present application, the image acquisition device 601 includes a camera and a position adjustment mechanism, and the position adjustment mechanism is used to drive the camera to move above each processing station, so that the image acquisition device 601 can accurately capture the image of each processing station, making it convenient for the controller to monitor each processing station.
