Description

Technical Field

[0001] The invention relates to the technical field of double-sided adhesive tape production, and in particular to a laser processing device used for double-sided adhesive tape production. Background Art

[0002] In some special application scenarios, double-sided tape needs to be cut into various complex shapes, such as round, oval, special-shaped, etc. With its high flexibility and precision, the laser cutting machine can easily cut according to the preset shape to meet the needs of different product designs. The laser cutting of double-sided tape is generally divided into half cutting and full cutting. Half cutting means that the laser beam only cuts a part of the tape, usually the tape layer, without cutting the release paper, which makes it easier to tear off the tape layer and paste it directly. Full cutting means that the laser beam completely cuts the double-sided tape.

[0003] When half-cutting, the double-sided tape is placed on the table of the laser cutting machine. The laser cutting machine is equipped with a laser cutting head and the movement direction of the X-axis and Y-axis is controlled by a gantry slide, so that the laser cutting head can flexibly half-cut the double-sided tape. However, some double-sided tapes are stored in rolls, and they will curl on both sides when unfolded, which is inconvenient to lay flat on the table of the laser cutting machine, which is easy to affect the quality of laser cutting. At the same time, if the laser beam of the laser cutting head needs to cut the edge of the double-sided tape, the curled edge is prone to uneven laser energy distribution, because when the laser beam is irradiated to the curled part, the reflection and refraction of the light are different from those on the flat surface, which is easy to cause local energy to be too high or too low. The area with too high energy will produce a burning phenomenon, which affects the appearance and performance of the double-sided tape. Summary of the invention

An elastic mechanism is provided between the lifting plate 15 and the upper end of the long plate 14, and an upward movement mechanism is provided between the lifting plate 15 and the block 2.

[0038] The elastic mechanism includes two connecting columns 20, which are symmetrically fixedly connected to the upper end of the long plate 14 corresponding to the lifting plate 15.

[0039] The upward movement mechanism includes an inclined plate 25 and a push block 27. The inclined plate 25 is fixedly connected to the lower end of the lifting plate 15 near the block 2.

[0040] The pushing assembly includes two concave plates 7 , one ends of the two concave plates 7 are respectively fixedly connected to the two side walls of the laser cutting head 5 , and the other ends of the two concave plates 7 are fixedly connected to the pushing plates 9 .

[0041] Working principle: When laser half-cutting the tape body 11, first place the tape body 11 on the upper end of the machine table 32, and the tape body 11 is exactly between the two positioning rods 10, then the tape body 11 can be positioned, and the tape body 11 can be adjusted to be as centered as possible relative to the two positioning rods 10, and then the two electric push rods 8 are started first, and the telescopic axes of the two electric push rods 8 are shortened. When each electric push rod 8 is in operation, the electric push rod 8 can drive the slide 4 in the slide groove 33 on the machine table 32 to one side edge of the tape body 11 When the U-shaped block 3 is moved, the slider 4 can drive the cross plate 21, multiple connecting rods 13, multiple springs 22 and the U-shaped block 3 to move together. The U-shaped block 3 will first slide horizontally on the upper end of the flat plate 29, and then the U-shaped block 3 will move downward along the inclined plate 2 30. At the same time, the multiple springs 22 are originally in a squeezed state, so the multiple springs 22 can be continuously opened, and the multiple connecting rods 13 on the U-shaped block 3 will slide down in the cross plate 21 until the bottom of the U-shaped block 3 moves to the flat plate 3 31. At this time, the springs 22 stop stretching, and the U-shaped block 3 and the connecting rods 13 stop moving downward.

[0042] It should be noted that the U-shaped block 3 can also drive the two L-shaped pressure plates 12 and the long plate 14 to move together during the movement. Then the two L-shaped pressure plates 12 and the long plate 14 will first move horizontally, then move obliquely downward, and finally move horizontally. Then the long plate 14 will drive the connected multiple guide pillars 17 and the multiple lifting plates 15 to move as described above. The blocks 2, concave plates 1, two pillars 26, pressure blocks 19, two springs 28 and splicing plates 16 connected to each guide pillar 17 will also move as described above. When the multiple pressure blocks 19 move horizontally after the oblique downward movement, they will lightly press on the upper surface of the tape body 11 and slide. Finally, the lower ends of the multiple pressure blocks 19 The two L-shaped pressure plates 12 slide to one edge of the upper surface of the tape body 11 and press there. At the same time, the two L-shaped pressure plates 12 will squeeze the upper ends of the two positioning rods 10 respectively when they move downward, so that the two positioning rods 10 slide downward in their corresponding slots 34 and squeeze a set of springs 5 ​​35 until the two L-shaped pressure plates 12 stop pressing the positioning rods 10 when they move horizontally after the downward movement, and the lower ends of the two L-shaped pressure plates 12 will slide and contact with the upper surface of the tape body 11 until they reach an edge of the upper surface of the tape body 11 and press there, and the two L-shaped pressure plates 12 are close to the corner of the upper surface of the tape body 11.

[0043] In view of the above, when the other electric push rod 8 is running, it is also like the above, and presses the other edge of the upper surface of the tape body 11, and the final state is as follows: Figure 1 and Figure 2As shown, the tape body 11 can be flattened from the middle to the outer edges on both sides, and the curled edges on both sides of the tape body 11 will also be flattened and pressed. Then the gantry slide 6 can drive the laser cutting head 5 to move along the X-axis direction or the Y-axis direction. The gantry slide 6 is a well-known prior art and will not be described in detail. Then, when the laser cutting head 5 performs laser half-cutting on the tape body 11, the flattened tape body 11 can improve the quality of laser half-cutting.

[0044] When the laser cutting head 5 moves to one side edge of the tape body 11 and the laser beam needs to scan one side edge of the tape body 11, the laser cutting head 5 will move toward a concave plate 1, and the push plate 9 connected to the laser cutting head 5 can push this concave plate 1. When this concave plate 1 is pushed, it will drive the block 2 to move together, and the block 2 will drive the guide column 17 to slide in the long plate 14 and squeeze the spring 18. The block 2 will also drive the two pillars 26, the pressure block 19, the two springs 28, the splicing plate 16 and the push block 27 to move together, and the push block 27 will squeeze the corresponding inclined plate 1 The inclined surface of 25 causes the inclined plate 1 25 to move upward, the inclined plate 1 25 will drive the flat plate 1 24 and the lifting plate 15 to move upward together, the lifting plate 15 will push the splicing plate 16 upward, and the lifting plate 15 will slide on the outer walls of the two connecting columns 20 and stretch the spring three 23, the splicing plate 16 will drive the two pillars 26 to move upward in the block 2, the two pillars 26 will drive the pressing block 19 to move upward, the pressing block 19 will squeeze the spring four 28, until the upper end of the push block 27 slides and contacts with the lower end of the flat plate 1 24, then the lifting plate 15, the splicing plate 16, the two pillars 26 and the pressing block 19 will stop moving upward and only move horizontally.

[0045] To sum up, that is to say, the pressing block 19 will first tilt upward and then move horizontally to loosen the edge away from the tape body 11, and there are still two corresponding pressing blocks 19 near the front and rear of the edge of the tape body 11 that is loosened here, and the two pressing blocks 19 still press the other edges of the tape body 11, so the edge of the tape body 11 that is loosened here will not curl automatically, thereby facilitating the laser cutting head 5 to half-cut the loosened edge of the tape body 11 here. When the laser cutting head 5 leaves the concave plate 1 with the push plate 9, the pressure block 19 will first translate and then tilt downward to press back to the edge of the tape body 11 under the action of spring 1 18, spring 3 23 and spring 4 28. The advantage of this is that it prevents the pressure block 19 from pushing the edge of the tape body 11. Because when the pressure block 19 loosens the curled edge of the tape body 11, although other pressure blocks 19 continue to restrict the other curled edges of the tape body 11, there may also be a phenomenon that the loosened edge is slightly warped (the effect of the slightly warped edge on the laser half-cutting of the tape body 11 is negligible). When the pressure block 19 first translates and then tilts downward to press back to the edge of the tape body 11, the slightly warped edge of the tape body 11 can be avoided. The laser half-cutting of other edge positions by the laser cutting head 5 is the same.

[0046] It should be noted that when the laser half-cutting is performed on the two side edges of the tape body 11, the multiple pressing blocks 19 that press the two side edges of the tape body 11 will avoid the laser beam in turn, and when the laser beam leaves the corresponding pressing blocks 19, they will automatically press back to the edge of the tape body 11, and will not push to the edge of the tape body 11 when returning. During the process, the two side edges of the tape body 11 are always in a flat state, thereby improving the laser half-cutting quality of the two side edges of the tape body 11 and avoiding affecting the appearance and performance of the tape body 11.
