Description

Technical Field

[0001] The utility model relates to the technical field of material strip cutting, in particular to a laser heating cross-cutting mechanism. Background Art

[0002] Prepreg, also known as PP sheet, refers to a thin sheet material made of treated fiberglass cloth, impregnated with resin glue, and then heat-treated (pre-baked) to make the resin enter the B stage. It is a sheet material that will soften under heating and pressure, and will react and solidify after cooling. Under the action of temperature and pressure, it can quickly solidify and complete bonding.

[0003] When using prepreg, a cutting machine is required to cut the entire roll of prepreg into sheets to meet the customer's product size requirements. Usually, the cutting area of ​​the prepreg is heated before being cut using a horizontal cutter that moves up and down. Currently, cutting machines on the market generally use servo electric cylinders or telescopic cylinders to achieve the cutting function of the cutter. However, using servo electric cylinders for cutting is relatively costly. Using telescopic cylinders for cutting consumes gas resources and has the disadvantage of being easily damaged, resulting in a high overall cost. Furthermore, the cutting efficiency and speed of PP sheets are relatively low when using telescopic cylinders.

[0004] The prior application utility model with application number CN202220487711.6 discloses a cam cutting device and a cutting machine. The cam cutting device includes: a frame; a motor; an electromagnetic clutch, which is fixedly mounted above the motor; a reducer, which includes a reducer input end and a reducer output end, the reducer input end is fixedly connected to the top of the electromagnetic clutch, and the reducer is fixedly mounted on the frame; a cam cutting mechanism, which is fixedly connected to the reducer output end via a cam main shaft, and the cam cutting mechanism is fixedly mounted on the frame; the cam cutting mechanism includes two cams arranged at intervals, a cutter height adjustment mechanism arranged below each cam, and a cutter mounting frame fixedly mounted below the cutter height adjustment mechanism, on which a cutter is mounted. The cam cutting device uses the characteristics of the cam to drive the cam to rotate with a motor to achieve the up and down movement of the cutter for cutting, thereby achieving higher cutting efficiency and faster cutting speed.

[0005] The PP sheet is heated by blowing hot air through the duct heater. After heating, the PP sheet will soften as a whole. When using the duct heater for heating, a water cooling system is required to dissipate the heat of the duct heater. The additional water cooling system will take up the space of the cutting machine and affect the layout of other structures. Utility Model Content

[0036] The present invention is described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-4 As shown, the laser heating cross-cutting mechanism includes a cross-cutting module 1 and a laser heating assembly 3 arranged above the cross-cutting module 1. The cross-cutting module 1 includes a cross-cutting support platform 2 and a cross-cutting knife seat 12 arranged longitudinally above the cross-cutting support platform 2. The cross-cutting knife seat 12 is equipped with a cross-cutting knife 16 arranged perpendicular to the direction of advance of the material strip. When the material strip needs to be cross-cut, it passes between the cross-cutting support platform 2 and the cross-cutting knife seat 12, which are arranged at intervals. When passing through, the cross-cutting knife seat 12 descends and the cross-cutting knife 16 cuts the passing material strip into segments.

[0038] The cross-cutting module 1 also includes a cross-cutting drive 11 that drives the cross-cutting blade holder 12 to move longitudinally. The cross-cutting drive 11 includes a rotatable transverse rotating shaft 13. The cross-cutting rotating shaft is embedded with an eccentric wheel 14. The eccentric wheel 14 is embedded with a transverse driving sleeve 15. The bottom of the transverse driving sleeve is connected to the cross-cutting blade holder 12. When the transverse rotating shaft 13 rotates, the eccentric wheel 14 rotates around the transverse rotating shaft 13 accordingly, thereby driving the cross-cutting driving sleeve to rise and fall once, achieving cutting.

[0039] It should be noted that the transverse rotating shaft rotates under the drive of the motor.

[0040] Furthermore, the crosscutting module 1 also includes transverse guide seats 21 arranged at both ends of the crosscutting knife seat 12. The transverse guide seat 21 is longitudinally formed with a guide movable groove 22 for the longitudinal movement of the crosscutting knife seat 12. The transverse guide seat 21 is provided with a first guide block 23 that moves along its length and extends into the guide movable groove 22, and a second guide block 24 that is arranged along its width and extends into the guide movable groove 22. The first guide block 23 extends into the guide movable groove 22 to change the width of the guide movable groove 22, so that the ends of the crosscutting knife seat 12 can slide with the first guide block 23 during longitudinal movement, thereby controlling the left and right lateral displacement of the crosscutting knife seat 12. The second guide block 24 extends into the guide movable groove 22 to change the length of the guide movable groove 22, so that the front or rear end surface of the crosscutting knife seat 12 can slide with the second guide block 24 during longitudinal movement, thereby controlling the front and rear lateral displacement of the crosscutting knife seat 12. This can prevent the crosscutting knife seat 12 from deviating too much from left to right and from front to back.

[0041] Preferably, the first guide block 23 and the second guide block 24 are driven by corresponding transverse telescopic cylinders 25 to achieve transverse movement.

[0042] The laser heating assembly 3 includes a heating drive seat 31, on which a plurality of spaced laser heating modules 4 are installed. Two adjacent laser heating modules 4 are connected to each other, and the plurality of laser heating modules 4 move synchronously along the length direction of the heating drive seat 31; the laser heating module 4 includes a laser emission head 42 facing the material strip and heating the material strip.

[0043] Before the material strip enters the cross-cutting module 1, it will pass through the laser heating assembly 3. Multiple laser heating modules 4 move synchronously along the length direction of the heating drive seat 31, so that the laser emission head 42 will move laterally. The heating path moves along the width direction of the material strip, heating the transverse cutting part of the material strip. The heated area is a straight line. When the heated material strip enters the cross-cutting module 1 for cutting, the generation of burrs can be reduced and the cutting quality can be improved. At the same time, there is no need to arrange a water-cooling heat dissipation module to dissipate heat for the laser heating module 4, which reduces the structural layout and reduces the overall weight, which is conducive to transporting boxes and handling.

[0044] Specific laser heating component 3: The heating drive seat 31 is arranged with a transverse drive member 32 and a transverse drive plate 33 installed on the transverse drive member 32 along the length direction, and multiple laser heating modules 4 are installed at intervals on the transverse drive plate 33. The transverse drive plate 33 moves along the length direction of the transverse drive member 32. When the cross-cutting part passes through the laser heating module 4, the transverse drive member 32 drives the transverse drive plate 33 to move horizontally, and multiple laser heating modules 4 move at the same time, so that the laser emission head 42 moves along the width direction of the material strip. The heating of the material strip by the laser emission head 42 can cover the cutting area, thereby ensuring the subsequent cutting quality.

[0045] Preferably, the transverse driving member 32 is a linear module; the linear module has better movement stability, ensuring that the heated area is a straight line and coincides with the cutting area.

[0046] Preferably, the transverse drive plate 33 is provided with an angle support seat 34 for mounting the laser heating module 4. The laser heating module 4 can be mounted on the angle support seat 34 so as to swing longitudinally. The laser heating module 4 includes a laser heating mounting seat 35 connected to the angle support seat 34. The laser heating mounting seat 35 is formed with a center connecting hole 36 arranged at intervals and an angle adjustment hole 37 arranged at intervals below the center connecting hole 36. The angle support seat 34 is formed with a center mounting hole 38 coaxially matched with the center connecting hole 36 and an arc-shaped long slot 39 arranged at intervals below the center mounting hole 38. The arc-shaped long slot 39 cooperates with the angle adjustment hole 37. The laser heating mounting seat 35 can cooperate with the angle adjustment hole 37 through the center connecting hole 36 to achieve longitudinal swing of the laser heating mounting seat 35 around the center connecting hole 36. After the laser heating mounting seat 35 is adjusted to the desired angle, the arc-shaped long slot 39 always cooperates with the angle adjustment hole 37 and is locked by bolts to prevent subsequent swinging. The laser heating mounting base 35 can be swung to adjust the orientation angle of the laser emission head 42 so that the heating point is away from or close to the cross-cutting module 1 .

[0047] The laser heating module 4 also includes a laser heater 41 mounted on the laser heating mount 35. This laser heater 41 is connected to a fin heat sink module 43, which is equipped with multiple cooling fans 44. The laser heater 41 uses laser light to directly heat the sample stage or sample, concentrating the heating power and minimizing the impact on the vacuum. The laser heater 41 also features rapid heating and cooling rates. Heat generated by the laser heater 41 is dissipated through the fin heat sink module 43 and cooling fans 44, lowering the ambient temperature and ensuring proper operation of the laser heater 41.

[0048] Furthermore, the laser heating assembly 3 also includes a top heat dissipation structure arranged above the laser heating module 4. The top heat dissipation structure includes a heat dissipation pipe 45 arranged along the moving direction of the laser heating module 4. The heat dissipation pipe 45 is equipped with multiple heat absorption holes 46 for extracting heat from the laser heating module 4. The heat dissipation pipe 45 is connected to multiple exhaust pipes 47 for discharging heat. After part of the heat generated by the laser heater 41 is discharged through the fin heat dissipation module 43 and the heat dissipation fan 44, part of the heat can also be absorbed through the heat absorption holes 46 of the heat dissipation pipe 45 arranged above, and then discharged outward through multiple exhaust pipes 47, further reducing the ambient temperature and ensuring the normal operation of the laser heater 41.

[0049] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0050] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
