Description

Technical Field

[0001] The utility model relates to the technical field of semi-cured sheet cutting, in particular to a laser heating cutting machine. Background Art

[0002] When processing a PCB board, it is necessary to cut the semi-cured sheet into sheet bodies of a specific size to meet the requirements of customers for the product size. Usually, when cutting a roll-shaped semi-cured sheet, it is necessary to first heat the cutting part of the semi-cured sheet, and then cut it with a transverse cutter and / or a longitudinal cutter after heating.

[0003] Among them, the invention with the application number CN202210219565.3 discloses a semi-cured sheet cutting machine, which includes a first frame and a second frame. A feeding mechanism, a longitudinal cutting mechanism, and a transverse cutting mechanism are arranged between the first frame and the second frame. The feeding mechanism includes a first floating shaft, a movable support plate, and a second floating shaft. The movable support plate of the present invention enables the semi-cured sheet to be guided into the transverse cutting mechanism from the feeding end more quickly during manual feeding, avoiding too long feeding time; the first floating shaft drives the semi-cured sheet to move downward under the action of gravity, so that the front-end semi-cured sheet is continuously transported, and the rear-end semi-cured sheet pauses for the longitudinal cutting process, realizing the process of continuous dynamic heating of the material, effectively improving the phenomenon of white edges caused by uneven heating; the second floating shaft enables the discarded part of the semi-cured sheet to always remain flat during the recycling process, and the recycled roll can be re-put on the feeding air shaft for reuse. Content of the Utility Model

[0004] The purpose of the utility model is to provide a laser heating cutting machine aiming at the deficiencies of the prior art.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A laser heating cutting machine, including a cutting frame, the cutting frame is provided with a vertical cutting mechanism, a material conveying mechanism, and a transverse cutting mechanism;

[0007] The vertical cutting mechanism includes a plurality of heating modules, the distance between adjacent two heating modules can be adjusted, the heating module includes a heating member and a cutting member, the heating member includes a heating box and a laser heating member installed in the heating box, a laser emitting head facing the material tape is installed at the bottom of the heating box, and the laser emitting head is connected to the laser heating member; the cutting member includes a vertical cutting knife located below the heating box, the vertical cutting knife is longitudinally aligned with the laser emitting head, and the vertical cutting knife is parallel to the moving direction of the material tape;

[0008] The material conveying mechanism includes a conveying frame, on which a front conveyor, a middle conveyor, and a rear conveyor are arranged. The front conveyor includes a first front conveyor roller, a second front conveyor roller, a front driving conveyor roller, and a front conveyor belt nested between the first front conveyor roller, the second front conveyor roller, and the front driving conveyor roller. A front tension adjusting member for adjusting the tension of the front conveyor belt is arranged on the outer side of the front conveyor belt.

[0009] The cross-cutting mechanism includes a cross-cutting module and a laser heating component arranged above the cross-cutting module. The cross-cutting module includes a cross-cutting support table and a cross-cutting tool holder movably arranged longitudinally above the cross-cutting support table. A transverse cutting knife perpendicular to the advancing direction of the strip is installed on the cross-cutting tool holder.

[0010] The laser heating component includes a heating driving seat, on which a plurality of laser heating modules are arranged at intervals. Two adjacent laser heating modules are connected to each other, and the plurality of laser heating modules move synchronously along the length direction of the heating driving seat. The laser heating module includes a laser emitting head facing the strip and heating the strip.

[0011] The beneficial effects of the present utility model: The whole raw material strip to be cut passes through the vertical cutting mechanism. At this time, the laser heating member of the heating module heats the area to be cut through the laser emitting head, making the area to be cut soften. Since the area heated by the laser emitting head is small, after the whole raw material passes through the heating module, the heated area is a straight line. Cooperating with the vertical cutting knife longitudinally aligned with the laser emitting head to cut the heated area can reduce the generation of burrs and will not heat too many areas, ensuring the cutting quality.

[0012] The material passing through the vertical cutting mechanism forms a long strip and enters the material conveying mechanism. After being conveyed, it enters the cross-cutting mechanism to cut the long strip into a segmented structure. Before the strip enters the cross-cutting module, it will pass through the laser heating component. The plurality of laser heating modules move synchronously along the length direction of the heating driving seat, so that the laser emitting head will move horizontally, and the heating path moves along the width direction of the strip to heat the transverse cutting area of the strip. The heated area is a straight line. When the heated strip enters the cross-cutting module for cutting, it can reduce the generation of burrs and improve the cutting quality. At the same time, there is no need to arrange a water-cooled heat dissipation module to dissipate heat for the laser heating module, reducing the structural layout and the overall weight, which is beneficial to transportation and handling.

[0051] The present utility model will be described in detail below in conjunction with the accompanying drawings.

[0052] As Figures 1-12 shown, a laser heating cutting machine includes a cutting machine frame 10, and the cutting machine frame 10 is provided with a vertical cutting mechanism 1 for processing semi-cured sheets, a material conveying mechanism 2, and a horizontal cutting mechanism 3.

[0053] The semi-cured sheet is wound around a reel, and after unwinding, a strip of material is formed and advanced for transportation.

[0054] The vertical cutting mechanism 1 includes a plurality of heating modules 11. The distance between two adjacent heating modules 11 can be adjusted. The heating module 11 includes a heating element and a cutting element. The heating element includes a heating box 111 and a laser heating element 112 installed in the heating box 111. A laser emitting head 113 is installed at the bottom of the heating box 111 and faces the strip of material 210. The laser emitting head 113 is connected to the laser heating element 112; the cutting element includes a vertical cutting knife 116 located below the heating box 111. The vertical cutting knife 116 is longitudinally aligned with the laser emitting head 113, and the vertical cutting knife 116 is parallel to the moving direction of the strip of material 210.

[0055] The entire raw material strip 210 to be cut passes through the vertical cutting mechanism 1. At this time, the laser heating element 112 of the heating module 11 heats the area to be cut through the laser emitting head 113, making the area to be cut soften. Since the area heated by the laser emitting head 113 is small, after the entire raw material passes through the heating module 11, the heated area is a straight line. Cooperating with the vertical cutting knife 116 longitudinally aligned with the laser emitting head 113 to cut the heated area can reduce the generation of burrs and will not heat too many areas, ensuring the quality of cutting.

[0056] The laser heating element 112 directly heats the sample stage or the sample with laser, has a concentrated heating power, has little influence on the vacuum; has a fast heating / cooling rate; is particularly suitable for an atmosphere with oxygen.

[0057] Preferably, there are two or more heating modules 11.

[0058] Preferably, there are three heating modules 11.

[0059] According to the cutting width of the strip of material 210 and the number of segments after cutting, the corresponding number of heating modules 11 is set.

[0060] The heating module 11 further includes a heating plate 110 for installing the heating box 111. A knife seat plate 114 is provided at the bottom of the heating plate 110. The knife seat plate 114 is installed with a driving knife seat 115. The vertical cutting knife 116 is installed on the driving knife seat 115. During heating, the vertical cutting knife 116 installed on the driving knife seat 115 located below cuts the entire raw material passing by to form a strip-shaped strip of material 210.

[0061] Furthermore, a sliding installation groove 117 is longitudinally formed on the tool holder plate 114, and a sliding block 118 that is slidably engaged with the sliding installation groove 117 is formed on the driving tool holder 115. The height of the vertical cutting tool 116 can be adjusted by the cooperation of the sliding block 118 and the sliding groove. After adjusting to the required height, it is locked with bolts to prevent it from being toggled up and down, which is convenient for stably cutting raw material sheets of different thicknesses.

[0062] Before cutting, the area where the laser emitting head 113 faces the raw material sheet is invisible to the naked eye, so the cutting area cannot be seen. In this regard, the heating plate 110 is also equipped with a heating guiding member. The heating guiding member includes an infrared emitter 119 whose angle can be adjusted. The emitting end of the infrared emitter 119 and the laser emitting head 113 of the laser heating member 112 both face the cutting area of the tape 210; the red dot emitted by the emitting end of the infrared emitter 119 coincides with the heating area of the laser emitting head 113. The cutting area can be observed according to the red dot emitted by the infrared emitter 119, and this heating area is also the cutting area, so that the cutting area can also be observed, which is convenient for observing the situation during cutting.

[0063] A heat dissipation module 12 for discharging the heat generated by the laser heating member 112 is provided in the heating box 111; the heat dissipation module 12 includes a heat conduction structure 122 composed of heat dissipation fins 121 and a heat dissipation fan 123 installed on the heat conduction structure 122. The heating box 111 is also formed with a heat dissipation grille 124 for the heat dissipation fan 123 to discharge heat outward. The laser heating member 112 generates a large amount of heat, which can be conducted through the heat dissipation fins 121 of the heat conduction structure 122 and discharged outside the heating box 111 through the heat dissipation fan 123 and the heat dissipation grille 124 to achieve heat dissipation.

[0064] The material formed by the vertical cutting mechanism 1 enters the material conveying mechanism 2 in a long strip shape.

[0065] The material conveying mechanism 2 includes a conveying machine frame. The conveying machine frame is provided with a front conveying member 21, a middle conveying member 22, and a rear conveying member 23. The front conveying member 21 includes a first front conveying roller 211, a second front conveying roller 212, a front driving conveying roller 213, and a front conveyor belt 2192 nested between the first front conveying roller 211, the second front conveying roller 212, and the front driving conveying roller 213. A front tension adjusting member for adjusting the tension of the front conveyor belt 2192 is provided on the outside of the front conveyor belt 2192;

[0066] The middle conveying member 22 includes a middle conveying roller 221 that can move longitudinally;

[0067] The rear conveying member 23 includes a first rear conveying roller 231, a rear driving conveying roller 232, and a rear conveyor belt 233 nested between the first rear conveying roller 231 and the rear driving conveying roller 232;

[0068] The first front conveyor roller 211, the second front conveyor roller 212, and the first rear conveyor roller 231 are arranged flush.

[0069] The strip 210 passes successively over the top of the first front conveyor roller 211, over the top of the second front conveyor roller 212, under the bottom of the middle conveyor roller 221, and over the top of the first rear conveyor roller 231. When passing through the middle conveyor roller 221, when the strip 210 becomes loose, the middle conveyor roller 221 descends, which can hold the strip 210 and increase the tension, preventing the decrease in conveying efficiency caused by the loosening of the strip 210; when the tension of the strip 210 during conveyance is too large, the middle conveyor roller 221 rises, thereby reducing the tension and preventing the strip 210 from breaking due to being too tight.

[0070] Specifically, the front conveyor member 21 further includes a front support table located between the first front conveyor roller 211 and the second front conveyor roller 212. A strip support plate 215 for supporting the strip 210 is installed on the top of the front support table. The strip support plate 215 is located below the vertical cutting knife 116. The strip support plate 215 can support the strip 210 to be cut, prevent the deformation of the strip 210 during cutting, and also prevent the strip 210 from being sunken when advancing, ensuring the support for the strip 210 and improving the quality of vertical cutting.

[0071] A front support seat 214 is installed at the bottom of the support table. The front support seat 214 is formed with a first adjustment long slot 216 along its length direction. The front support seat 214 is installed on the conveyor frame with adjustable height through the first adjustment long slot 216. Guide pieces 2191 bent outward are respectively formed at both ends of the strip support plate 215; the guide pieces 2191 play a guiding role, facilitating the guiding and frictional cooperation of the strip 210 with the strip support plate 215; through the cooperation of the first adjustment long slot 216 and the conveyor frame, the height of the front support seat 214 can be adjusted, thereby adjusting the height of the support for the strip 210.

[0072] The front tension adjustment member includes a tension adjustment seat 217 arranged obliquely. A front tension wheel 218 that rolls with the front conveyor belt 2192 is installed at the outer end of the tension adjustment seat 217. The tension adjustment seat 217 is formed with a second adjustment long slot 219 along its length direction. The tension adjustment seat 217 is installed on the conveyor frame with adjustable position through the second adjustment long slot 219; when the tension of the front conveyor belt 2192 does not meet the current conveying requirements, the position of the tension adjustment seat 217 can be adjusted, thereby adjusting the pressing degree of the front tension wheel 218 in contact with the front conveyor belt 2192, making the front conveyor belt 2192 convey the strip 210 more stably and preventing the strip 210 from stagnating and not advancing.

[0073] Preferably, the number of the tension adjusting seats 217 is two. The two tension adjusting seats 217 are arranged symmetrically in mirror image on both sides of the front conveyor belt 2192. The two tension adjusting seats 217 move simultaneously. The path of movement of the tension adjusting seats 217 does not need to be large to adjust the tension of the front conveyor belt 2192, and the efficiency during adjustment is higher.

[0074] Further, the middle conveyor member 22 further includes a vertically arranged lifting driving member. A roller mounting seat 222 is installed at the driving end of the lifting driving member. The end of the middle conveyor roller 221 is mounted on the roller mounting seat 222. When the strip 210 passes through the middle conveyor roller 221, when the strip 210 becomes loose, the middle conveyor roller 221 descends, and the strip 210 can be pulled to increase the tension force and prevent the decrease of the conveying efficiency caused by the looseness of the strip 210. When the tension force during the conveyance of the strip 210 is too large, the middle conveyor roller 221 rises, thereby reducing the tension force and preventing the breakage of the strip 210 caused by being too tight.

[0075] Preferably, the lifting driving member is a lifting cylinder 223. Driven by the lifting cylinder 223, the middle conveyor roller 221 installed on the roller mounting seat 222 can be lifted and lowered, so that the tension of the strip 210 passing through the middle conveyor roller 221 can be adjusted to ensure the stable and smooth forward conveyance of the strip 210.

[0076] Further, a linear guide rail 224 is also arranged beside the guide rod. A linear sliding seat 225 is slidably mounted on the linear guide rail 224 along the length direction. The linear sliding seat 225 is connected to the roller mounting seat 222. When the roller mounting seat 222 moves up and down, the linear sliding seat 225 connected to the roller mounting seat 222 slides along the linear guide rail 224, further ensuring its lifting stability. When the middle conveyor roller 221 moves up and down, the lateral position of the middle conveyor roller 221 is ensured and there is no lateral deviation.

[0077] The material conveying mechanism 2 continues to convey the strip-shaped strip 210 to the cross-cutting mechanism 3, and the strip-shaped strip 210 is cut into a segmented structure by the cross-cutting mechanism 3.

[0078] The cross-cutting mechanism 3 includes a cross-cutting module 31 and a laser heating assembly 33 arranged above the cross-cutting module 31. The cross-cutting module 31 includes a cross-cutting support table 32 and a cross-cutting tool holder 312 movably arranged longitudinally above the cross-cutting support table 32. A transverse cutting tool 316 perpendicular to the advancing direction of the strip 210 is installed on the cross-cutting tool holder 312. When the strip 210 needs to be cross-cut, the strip 210 passes between the spaced transverse support seats and the cross-cutting tool holder 312. When passing through, the cross-cutting tool holder 312 descends and cuts the passing strip 210 into segments through the transverse cutting tool 316.

[0079] The cross-cutting module 31 also includes a cross-cutting driving member 311 that drives the cross-cutting blade seat 312 to move longitudinally. The cross-cutting driving member 311 includes a rotatable transverse rotating shaft 313. The cross-cutting rotating shaft is embedded with an eccentric wheel 314. The eccentric wheel 314 is embedded with a transverse driving sleeve 315. The bottom of the cross-cutting driving sleeve is connected to the cross-cutting blade seat 312. When the transverse rotating shaft 313 rotates, the eccentric wheel 314 rotates around the transverse rotating shaft 313 accordingly, thereby driving the cross-cutting driving sleeve to rise and fall once to achieve cutting.

[0080] It should be noted that the transverse rotating shaft rotates under the drive of the motor.

[0081] Furthermore, the transverse cutting module 31 also includes a transverse guide seat 321 arranged at both ends of the transverse cutting knife seat 312, and the transverse guide seat 321 is longitudinally formed with a guide movable groove 322 for the longitudinal movement of the transverse cutting knife seat 312. The transverse guide seat 321 is arranged with a first guide block 323 that moves along its length direction and penetrates into the guide movable groove 322, and a second guide block 324 that is arranged along its width direction and penetrates into the guide movable groove 322; the first guide block 323 penetrates into the guide movable groove 322 to change the width of the guide movable groove 322, so that the two ends of the transverse cutting knife seat 312 can slide with the first guide block 323 when the transverse cutting knife seat 312 moves longitudinally, and the transverse displacement of the transverse cutting knife seat 312 can be controlled. The second guide block 324 penetrates into the guide movable groove 322 to change the length of the guide movable groove 322, so that the front end face or the rear end face of the transverse cutting knife seat 312 can slide with the second guide block 324 when the transverse cutting knife seat 312 moves longitudinally, and the transverse displacement of the transverse cutting knife seat 312 can be controlled. This can prevent the cross-cutting knife seat 312 from deviating left and right and front and back at excessive angles.

[0082] Preferably, the first guide block 323 and the second guide block 324 are driven by corresponding transverse telescopic cylinders 325 to achieve transverse movement.

[0083] The laser heating assembly 33 includes a heating drive seat 331, on which a plurality of laser heating modules 34 are installed at intervals, two adjacent laser heating modules 34 are connected to each other, and the plurality of laser heating modules 34 move synchronously along the length direction of the heating drive seat 331; the laser heating module 34 includes a laser emission head 342 facing toward the material strip 210 and heating the material strip 210.

[0084] Before the strip 210 enters the cross-cutting module 31, it will pass through the laser heating assembly 33. Multiple laser heating modules 34 move synchronously along the length direction of the heating driving seat 331, so that the laser emitting head 342 will move horizontally. The heating path moves along the width direction of the strip 210 to heat the transverse cutting area of the strip 210. The heated area is a straight line. When the heated strip 210 enters the cross-cutting module 31 for cutting, the generation of burrs can be reduced, the cutting quality can be improved. At the same time, there is no need to arrange a water-cooled heat dissipation module to dissipate heat from the laser heating module 34, which reduces the structural layout, lowers the overall weight, and is beneficial for transportation and handling.

[0085] Specifically, for the laser heating assembly 33: a transverse driving member 332 is arranged along the length direction of the heating driving seat 331 and a transverse driving plate 333 is installed on the transverse driving member 332. Multiple laser heating modules 34 are installed at intervals on the transverse driving plate 333. The transverse driving plate 333 moves along the length direction of the transverse driving member 332. When the cross-cutting position passes through the laser heating module 34, the transverse driving member 332 drives the transverse driving plate 333 to move horizontally, and multiple laser heating modules 34 move simultaneously, so that the laser emitting head 342 moves along the width direction of the strip 210. The heating of the strip 210 by the laser emitting head 342 can cover the cutting area to ensure the subsequent cutting quality.

[0086] Preferably, the transverse driving member 332 is a linear module; the moving stability of the linear module is better, ensuring that the heated area is a straight line and coincides with the cutting area.

[0087] Preferably, the transverse driving plate 333 is provided with an angle support seat 334 for installing the laser heating module 34, and the laser heating module 34 is installed on the angle support seat 334 so as to be able to swing longitudinally; the laser heating module 34 includes a laser heating mounting seat 335 connected to the angle support seat 334. The laser heating mounting seat 335 is formed with centrally connecting holes 336 arranged at intervals and angle adjustment holes 337 arranged at intervals below the centrally connecting holes 336; the angle support seat 334 is formed with a central mounting hole 338 coaxially matched with the centrally connecting holes 336 and an arc-shaped long groove 339 arranged at intervals below the central mounting hole 338, and the arc-shaped long groove 339 is matched with the angle adjustment holes 337. The laser heating mounting seat 335 can be matched through the centrally connecting holes 336 and the angle adjustment holes 337 to realize that the laser heating mounting seat 335 can swing longitudinally around the centrally connecting holes 336. After the laser heating mounting seat 335 is adjusted to the required angle, the arc-shaped long groove 339 is always matched with the angle adjustment holes 337, and it is locked and connected by bolts to prevent subsequent swinging. Swinging the laser heating mounting seat 335 can adjust the orientation angle of the laser emitting head 342 to make the heating point far from or close to the cross-cutting module 31.

[0088] The laser heating module 34 further includes a laser heater 341 installed on the laser heating mount 335. The laser heater 341 is connected to a fin heat dissipation module 343, and a plurality of rear cooling fans 344 are installed on the fin heat dissipation module 343. The laser heater 341 directly heats the sample stage or the sample with laser, with concentrated heating power, little impact on the vacuum, and fast heating / cooling rate. The heat generated by the laser heater 341 can be discharged through the fin heat dissipation module 343 and the rear cooling fans 344, reducing the ambient temperature and ensuring the normal operation of the laser heater 341.

[0089] Furthermore, the laser heating assembly 33 further includes a top heat dissipation structure arranged above the laser heating module 34. The top heat dissipation structure includes a heat dissipation pipe 345 arranged along the moving direction of the laser heating module 34. A plurality of heat absorption holes 346 for extracting the heat of the laser heating module 34 are installed on the heat dissipation pipe 345, and the heat dissipation pipe 345 is connected to a plurality of discharge pipes 347 for discharging the heat. After a part of the heat generated by the laser heater 341 is discharged through the fin heat dissipation module 343 and the rear cooling fans 344, a part of the heat can also be absorbed through the heat absorption holes 346 of the heat dissipation pipe 345 arranged above, and then discharged outward through a plurality of discharge pipes 347, further reducing the ambient temperature and ensuring the normal operation of the laser heater 341.

[0090] In summary, it can be seen that the present utility model has the excellent characteristics described above, enabling it to enhance the efficiency unprecedented in the prior art during use and having practicality, thus becoming a product with extremely high practical value.

[0091] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
