Description

Pulsating wire feeding mechanism and vacuum coating machine Technical Field

[0001] This invention relates to the field of vacuum coating technology, and more particularly to a pulsed wire feeding mechanism and a vacuum coating machine. Background Technology

[0002] A pulsed wire feeding mechanism is a device in vacuum coating equipment used to intermittently and regularly supply coating material wires to the evaporation source or other coating areas. Pulsed wire feeding enables the coating metal wires to enter the evaporation boat more evenly for coating, which helps to improve the uniformity and consistency of the coating, reduce the fluctuation and defects in the coating thickness, and thus improve the quality of the coated products.

[0003] Chinese Patent Application No. CN202310474679.7 discloses a vacuum coating equipment and its usage method. This equipment uses a rotary feeding method to transport the substrate through the inlet into the coating chamber. Then, through a screw and nut transmission component, an upper drive component, and a lower drive component, the side sealing plate, upper sealing plate, and lower sealing plate are simultaneously activated, completely sealing the substrate and supporting part within the inlet. Vacuuming and coating processes are then performed. After coating, the coated substrate is rotated and transported again until unloading is complete. In the vacuum coating process, existing technologies evaporate metal wires into a gaseous state for coating. However, if the cutting length of the metal wire is controlled solely by stroke or time, although the error appears small in the wire state, volume differences will occur in the gaseous state, leading to inconsistent coating amounts and uneven coating.

[0047] The fixed-length wheel part 5 also includes a locking shaft part 52 and a fastening part 53. The locking shaft part 52 is fixedly disposed in front of the side wall of the power source housing. The cutter part 51 is sleeved on the outer ring of the locking shaft part 52. The fastening part 53 is inserted between the cutter part 51 and the locking shaft part 52.

[0048] The cutting section 51 includes a locking shaft assembly, a cutting blade assembly, and a cutting blade plate assembly.

The springs 516 are located in the receiving grooves 514. The top end of the spring 516 is fixedly connected to the fixed-length wheel 511, and the bottom end is fixedly connected to the slider 515. The cutting blade guide grooves 512 are all disposed on the inner wall of the fixed-length wheel 511. The cutting blade plate 517 is fixedly disposed on the front side of the fixed-length wheel 511, and the cutting blade plate holes 518 are all through the cutting blade plate 517.

[0049] It should be noted that the bottom edge of the cutter body 513 is inclined at an angle of 60°.

[0050] The locking shaft part 52 includes a locking shaft body 521, a plurality of locking shaft guide grooves 522 and a locking shaft plate assembly. The locking shaft plate assembly includes a locking shaft plate 523 and a plurality of locking shaft plate holes 524. The locking shaft guide grooves 522 are all located on the outer ring of the locking shaft body 521. The locking shaft plate 523 is fixedly located on the front side of the locking shaft body 521. The locking shaft plate holes 524 are all through the locking shaft plate 523.

[0051] The fastening part 53 includes a fastening ring assembly and a protrusion assembly. The fastening ring assembly includes a fastening ring 531, a plurality of outer guide bars 532 and a plurality of inner guide bars 533. The protrusion assembly includes a protrusion 534 and a limiting hole 535. The outer guide bars 532 are all fixedly disposed on the outer ring of the fastening ring 531, and the inner guide bars 533 are all fixedly disposed on the inner ring of the fastening ring 531. The protrusion 534 is fixedly disposed on the front end of the outer ring of the fastening ring 531, and the limiting hole 535 is disposed through the protrusion 534.

[0052] The outer guide bar 532 is inserted into the corresponding cutter guide groove 512, and the inner guide bar 533 is inserted into the corresponding locking shaft guide groove 522, connecting the cutter part 51, the locking shaft part 52, and the fastening part 53 together, preventing the cutter part 51 and the fastening part 53 from rotating relative to the locking shaft part 52, so that the cutter body 513 cannot cut the metal wire.

[0053] The front side wall of the fastening ring 531 is provided with a locking part 54 and a handle part 55. The locking part 54 includes a connecting block 541, a threaded rod 542, a threaded sleeve 543, and a limiting post 544. The handle part 55 includes a handle body 551 and several protrusions 552. The handle body 551 is fixedly connected to the fastening ring 531. The protrusions 552 are all fixedly disposed on the outside of the handle body 551. The connecting block 541 is fixedly connected to the fastening ring 531. The threaded rod 542 is fixedly disposed above the connecting block 541. The threaded sleeve 543 is threadedly sleeved on the outer ring of the threaded rod 542. The limiting post 544 is fixedly disposed at the top of the threaded sleeve 543.

[0054] The diameter of the limiting post 544 is smaller than the diameter of the cutter plate hole 518 and the locking shaft plate hole 524, ensuring that the limiting post 544 can be smoothly inserted into the cutter plate hole 518 and the locking shaft plate hole 524, fixing the cutter part 51 and the fastening part 53 on the locking shaft part 52, and preventing the cutter part 51 and the fastening part 53 from falling off the locking shaft part 52.

[0055] The cutter plate 517 is engraved with scales. When the limiting post 544 is inserted into the corresponding cutter plate hole 518, the scale corresponding to the cutter plate hole 518 is the distance that the fastening part 53 moves. Since the bottom edge of the cutter body 513 is inclined at an angle of 60°, the length of the cutter body 513 protruding from the fixed length wheel 511 can be calculated based on the distance that the fastening part 53 moves, according to the calculation rules of the side length of a right triangle. The circumference of the circular trajectory formed by this length plus the radius of the fixed length wheel 511 is the length of the metal wire cut.

[0056] Since the knob 62 is rotatably connected to the baffle 61, and the screw 63 is fixedly connected to the pressure adjusting shaft 64, and the knob 62 is threadedly connected to the screw 63, turning the knob 62 will cause the screw 63 to slide up and down. The screw 63 will cause the pressure adjusting shaft 64 to slide up and down in the guide groove 32, thereby adjusting the distance between the wire feeding roller 7 and the fixed length wheel 5. Turning the knob 62 will cause the screw 63 to move upward, increasing the distance between the wire feeding roller 7 and the fixed length wheel 5, making it easier for the metal wire to pass through. The metal wire on the wire feeding roller 2 will be pulled out, and one end of the metal wire will be inserted into the left wire feeding tube 15 and passed between the wire feeding roller 7 and the fixed length wheel 5, and finally inserted into the right wire feeding tube 16. Turning the knob 62 in the opposite direction will drive the screw 63 to move downward. The screw 63 will push the wire feeding roller 7 downward through the pressure adjusting shaft 64 and press it against the outer ring of the fixed length wheel 511, clamping the metal wire between the two. The servo motor 31 is started, driving the locking shaft body 521 to rotate. The locking shaft body 521 drives the fixed length wheel 511 to rotate via the fastening ring 531. The fixed length wheel 511 drives the wire feeding pressure wheel 7 to rotate together through friction, pushing the metal wire forward along the right wire feeding tube 16. When the cutter body 513 rotates with the fixed length wheel 511 to the tangent point between the wire feeding pressure wheel 7 and the fixed length wheel 511, the cutter body 513 cuts the metal wire under the pressure of the wire feeding pressure wheel 7. Since the height of the cutter body 513 protruding from the fixed length wheel 511 remains unchanged, the cut metal wire... The wires are of equal length, each equal to the circumference of the outer edge of the cutter body 513. After the wire is cut, the servo motor 31 stops working, the knob 62 is turned to lift the wire feeding roller 7, pull the left wire through the wire feeding roller 7 and the fixed length roller 511, and extend it into the right wire feeding tube 16. Then the wire feeding roller 7 is pressed on the fixed length roller 511, the servo motor 31 starts working again, continues to push the wire in the left wire feeding tube 15 to the right wire feeding tube 16, and pushes the previously cut wire in the right wire feeding tube 16 forward. This cycle is repeated to complete the wire feeding.

[0057] When the length of the cut wire needs to be changed, rotate the threaded sleeve 543 to move it downward along the threaded rod 542, pulling the limiting post 544 out of the cutter plate hole 518 and the locking shaft plate hole 524, so that the limiting post 544 no longer restricts the cutter plate 517 and the locking shaft plate 523. Pinch the handle part 55 and pull it outward to pull the fastening part 53 out of the cutter part 51. The fastening ring 531 no longer lifts the cutter body 513 upward, the spring 516 rebounds, and pushes the cutter body 513 into the length-fixing wheel 511 through the slider 515. The top surface of the cutter body 513 is lower than the outer surface of the length-fixing wheel 511 to prevent accidental injury from the cutter body 513 when replacing the cutter part 51. After the fastening part 53 is pulled out, remove the cutter part 51 from the locking shaft part 52 and replace it with a length-fixing wheel of appropriate radius. 511. Place the new fixed-length wheel 511 onto the locking shaft part 52, and then insert the fastening part 53 into the gap between the cutter part 51 and the locking shaft part 52, so that the outer guide bar 532 is located in the cutter guide groove 512, the inner guide bar 533 is located in the locking shaft guide groove 522, and the cutter plate 517 is located directly above the locking shaft plate 523. At the same time, the limiting post 544 is located directly below the cutter plate 517 and the locking shaft plate 523. Push the fastening part 53 inward. Since the bottom edge of the cutter body 513 is inclined and the outer end is higher than the inner end, when the fastening ring 531 moves forward, it pushes the cutter body 513 upward, pushing the cutter body 513 out of the fixed-length wheel 511, which facilitates the cutting of the metal wire. Then rotate the threaded sleeve 543 to push the limiting post 544 into the locking shaft plate hole 524 and the cutter plate hole 518 in sequence. In the process, the cutter part 51 and the fastening part 53 are fixed on the locking shaft part 52 to prevent the cutter part 51 and the fastening part 53 from being thrown out when the servo motor 31 drives the locking shaft part 52 to rotate. If the radius of the replaced length-keeping wheel 511 is small, the wire feeding pressure wheel 7 needs to be moved downward to press the metal wire onto the length-keeping wheel 511. If the radius of the replaced length-keeping wheel 511 is large, the wire feeding pressure wheel 7 needs to be moved upward to press the metal wire onto the length-keeping wheel 511. If the length of the metal wire is to be finely adjusted, the cutter part 51 does not need to be replaced. When the fastening part 53 is pulled out from between the cutter part 51 and the locking shaft part 52, the cutter body 513 moves downward under the action of the spring 516, the length protruding from the length-keeping wheel 511 decreases, its trajectory circumference decreases, and the length of the metal wire cut decreases accordingly. The fastening part 513 is then pulled out from between the cutter part 51 and the locking shaft part 52. When the cutting part 51 and the locking part 52 are pushed inward, the fastening ring 531 pushes the cutting body 513 to move upward on the spring 516, increasing the length of the protruding fixed length wheel 511 and its trajectory circumference, thus increasing the length of the cut metal wire. After adjusting the position of the fastening part 53, the limiting pin 544 is inserted into the corresponding cutting plate hole 518 and locking plate hole 524. The scale on the cutting plate 517 shows the length of the cutting body 513, thereby determining the length of the cut metal wire. Through this precise control method, the amount of coating metal wire can be accurately controlled, thereby achieving precise control of the amount of coating material deposited, and thus accurately controlling the thickness of the coating, effectively improving the uniformity and consistency of the coating, and thus improving the quality of subsequent coated products.
