Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, and in particular to a laser mesh cutting mechanism. Background Art

[0002] The working principle of the VC heat spreader of mobile phones is that liquid water vaporizes at high temperature in a closed vacuum environment. The phase change of water takes away the heat from the heat source. The reflux of liquid water is achieved through the capillary action of the capillary mesh. The area of ​​the capillary mesh also plays a role in locking the water volume in the cavity of the VC heat spreader. Therefore, the capillary mesh needs to be contoured to the maximum extent in the VC heat spreader to ensure the area, so as to ensure sufficient water volume in the cavity. At the same time, the capillary mesh needs to be flat, stable and fixed in the cavity to ensure performance and life.

[0003] The capillary mesh is a mesh structure with a wire diameter of 0.025-0.04mm and a thickness of 0.05-0.1mm after weaving, such as a copper mesh. It is manufactured in rolls by manufacturers. The traditional VC process is punched and formed by cutting dies and stamping dies, and the gap between the punch and the lower die hole is designed to be 0.005mm. In the production process, since the wire diameter of the capillary mesh is very thin, the punch may be cut from the middle of the capillary mesh wire diameter, which is prone to problems such as die jamming, wire drawing, and head collapse, resulting in a shortened service life of the cutting die and stamping die, which generally need to be replaced or repaired every 7-10 days; at the same time, the matching mold also needs to be replaced when the product is changed.

[0066] In some embodiments, the fixture picking and placing mechanism 50 includes a support frame 501, which can be installed on the stand 20 in a removable manner or can be integrally formed with the stand 20. The support frame 501 is provided with at least one slide rail 502 extending along the first direction X, and the slide rail 502 is slidably mounted with a support plate 503, which can move along the first direction X.

[0068] In some embodiments, in order to press the jig 506 against the capillary net 100 in the third direction Z, the jig placement mechanism 50 also includes a first cylinder 504. The piston end of the first cylinder 504 is provided with an electromagnet 505. The first cylinder 504 can drive the electromagnet 505 to move along the first direction X. The electromagnet 505 is used to absorb the jig 506. The use of the electromagnet 505 is conducive to the replacement of the jig 506 to meet the replacement of the corresponding model of the jig 506 when the product is changed. Compared with the prior art, there is no need to replace the matching mold, thereby reducing the production cost.

[0069] In some embodiments, in order to ensure the position of the electromagnet 505 to absorb and grasp the jig 506 and the accuracy of pressing it onto the capillary net 100, a positioning column 5051 is provided on the side of the electromagnet 505 facing the cutting station, and the jig 506 is provided with a positioning hole 5061, and the positioning column 5051 matches the positioning hole 5061.

[0070] In other embodiments, the number of positioning posts 5051 and positioning holes 5061 is at least one. It should be noted that "at least one" is used to indicate quantity, such as one, two, three, etc., unless otherwise clearly and specifically defined, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be regarded as the scope of protection of the present invention.

[0071] In some embodiments, in order to avoid the capillary mesh 100 from being offset during the process of the jig 506 pressing the capillary mesh 100 and laser cutting, the jig pick-and-place mechanism 50 also includes a second cylinder 508 and a pressure plate 509.

Therefore, when the capillary mesh 100 moves into place along the second direction Y, the relative second cylinders 508 respectively drive the corresponding pressure plates 509 to press on the capillary mesh 100, thereby limiting the movement of the capillary mesh 100 in the second direction Y; ensuring that the capillary mesh 100 corresponding to the cutting station is in a stationary and fixed state during the laser cutting process, thereby ensuring the processing accuracy.

[0072] In some embodiments, the material receiving and supporting mechanism 60 includes a linear module 601, a first mounting frame 602, a third cylinder 603, a second mounting frame 604 and a supporting plate 605; wherein, the linear module 601 extends along a first direction X, the first mounting frame 602 is connected to the linear module 601, the linear module 601 can drive the first mounting frame 602 to move along the first direction X, the third cylinder 603 is connected to the first mounting frame 602, the second mounting frame 604 is connected to the piston end of the third cylinder 603, the third cylinder 603 can drive the second mounting frame 604 to move along a third direction Z, and the supporting plate 605 is arranged on the second mounting frame 604, for supporting the capillary net 100. In this way, after the capillary net 100 is moved into place, the linear module 601 controls the position of the top support plate 605 in the first direction X, and the third cylinder 603 controls the height of the top support plate 605 in the third direction Z, so that the top support plate 605 can support the capillary net 100 from the bottom, and the fixture 506 can be relative to the top support plate 605 in the third direction Z after being lowered, thereby pressing and fixing the capillary net 100 to facilitate precise net cutting by the laser cutting module 80.

[0073] In some embodiments, the top support plate 605 is provided with adsorption holes, which are connected to a vacuum source, and the top support plate 605 fixes the capillary mesh 100 through vacuum negative pressure adsorption.

[0074] In other embodiments, when the fixture 506 is in place, the electromagnet 505 is powered off, and the fixture 506 can also clamp the capillary mesh 100 in the third direction Z with the top support plate 605 through vacuum negative pressure adsorption of the top support plate 605 .

[0075] In some embodiments, the laser mesh cutting mechanism also includes a lifting module 70, which is disposed on the vertical frame 60, and the laser cutting module 80 is installed on the lifting module 70. The lifting module 70 can drive the laser cutting module 80 to move along the third direction Z, so that the laser cutting module 80 can cut the capillary mesh 100 for different models of products.

[0076] In some embodiments, since the manufacturer manufactures the capillary mesh 100 in rolls, in order to facilitate automatic control, the laser mesh cutting mechanism also includes a unwinding mechanism 30 and a rewinding mechanism 40. The unwinding mechanism 30 is arranged on the workbench 10 and placed at the feeding end of the stand 20. The unwinding mechanism 30 is used to unwind the capillary mesh 100 and transport it to the cutting station. The rewinding mechanism 40 is arranged on the workbench 10 and placed at the discharging end of the stand 20. The rewinding mechanism 40 is used to rewind the waste of the capillary mesh 100 after laser cutting; in this way, the capillary mesh 100 is unrolled by the unwinding mechanism 30 and transported to the cutting station, and then connected to the rewinding mechanism 40 to realize automatic rewinding; it should be noted that the unwinding mechanism 30 and the rewinding mechanism 40 are both controlled by servo motors to unwind and rewind, so as to ensure the movement accuracy of the capillary mesh 100, avoid waste of materials and avoid defective products due to inadequate movement.

[0077] In some embodiments, in order to avoid dust contamination of the capillary mesh 100 during laser cutting, the laser mesh cutting mechanism also includes a dust collection module 90, which is arranged on the side of the workbench 10 facing away from the stand 20, and the fixture pick-up and placement mechanism 50 also includes a plurality of dust suction mechanisms 510 surrounding the cutting station, and the plurality of dust suction mechanisms 510 are all connected to the dust collection module 90 pipeline. In this way, the dust generated during the laser mesh cutting process can be solved by the dust suction mechanism 510 and the dust collection module 90, ensuring that the capillary mesh will not be contaminated. At the same time, the manufacturer no longer has to worry about repairing and maintaining the mold during the production process, which greatly improves production efficiency and reduces production costs.

After moving into place, the linear module 601 controls the position of the top support plate 605 in the first direction X, and the third cylinder 603 controls the height of the top support plate 605 in the third direction Z, so that the top support plate 605 can support the capillary net 100 from the bottom and start negative pressure adsorption. After the electromagnet 505 is energized, the magnetic adsorption fixture 506 is used. The fixture 506 moves along the first direction X under the action of the first cylinder 504 to press the capillary net 100, and the laser cutting module 80 starts cutting the net. At the same time, the full-circle dust suction mechanism 510 is started. The dust suction mechanism 510 uses negative pressure to absorb the generated dust into the centralized dust collection module 90. After the full-circle cutting is completed, the capillary net material receiving mechanism removes the cut capillary net. Repeat the next round.
