Description

Technical Field

[0001] The utility model relates to the technical field of tape cutting, in particular to a laser heating vertical cutting mechanism. Background Art

[0002] The prepreg, also known as "PP sheet", is one of the main materials in the production of multilayer boards. It is mainly composed of resin and reinforcing materials. The reinforcing materials are divided into several types such as fiberglass cloth, paper base, and composite materials. Most of the prepregs (bonding sheets) used in the production of multilayer printed boards use fiberglass cloth as the reinforcing material.

[0003] When processing a PCB board, it is necessary to cut the prepreg into sheet-like bodies of a specific size to meet the requirements of customers for the product size. Usually, when cutting a roll-shaped prepreg, it is necessary to heat the cutting part of the prepreg first, and then cut it with a cross cutter and / or a vertical cutter after heating.

[0004] The invention with the application number CN202210219565.3 discloses a prepreg cutting machine, which includes a first frame and a second frame. A feeding mechanism, a vertical cutting mechanism, and a cross 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 prepreg to be guided into the cross cutting mechanism from the loading end more quickly during manual loading, avoiding too long loading time; the first floating shaft drives the prepreg to move downward under the action of gravity, so that the front-end prepreg is continuously transported, and the rear-end prepreg pauses transportation for the vertical cutting process, realizing the process of continuously and dynamically heating the material, effectively improving the phenomenon of white edges caused by uneven heating; the second floating shaft enables the discarded part of the prepreg to always remain flat during the recycling process, and the recycled roll can be put back on the loading air shaft for reuse.

[0005] When the existing cutting machine heats up, it heats the PP sheet by blowing hot air through a heater. After heating, the whole PP sheet will soften. The heated area is large, resulting in overall softening, affecting subsequent forward transportation and cross cutting, and resulting in poor cutting quality. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a laser heating vertical cutting mechanism for the deficiencies of the existing technology.

[0007] To achieve the above purpose, the technical solution of the utility model is as follows:

[0008] Laser heating vertical cutting mechanism, including a plurality of heating modules, the distance between two adjacent heating modules can be adjusted. The heating module includes a heating element and a cutting element. The heating element includes a heating box and a laser heating element installed in the heating box. A laser emitting head facing the tape is installed at the bottom of the heating box, and the laser emitting head is connected to the laser heating element; the cutting element 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 tape.

[0009] Furthermore: The heating module further includes a heating plate for installing the heating box. A knife seat plate is provided at the bottom of the heating plate, and a driving knife seat is installed on the knife seat plate. The vertical cutting knife is installed on the driving knife seat.

[0010] Furthermore: The knife seat plate is longitudinally formed with a sliding installation groove, and the driving knife seat is formed with a sliding block that slidably cooperates with the sliding installation groove.

[0011] Furthermore: The heating plate is also installed with a heating guiding member. The heating guiding member includes an infrared emitter whose angle can be adjusted. The emitting end of the infrared emitter and the laser emitting head of the laser heating element both face the cutting area of the tape.

[0012] Furthermore: A heat dissipation module for discharging the heat generated by the laser heating element is provided in the heating box.

[0013] Furthermore: The heat dissipation module includes a heat conduction structure composed of heat dissipation fins and a heat dissipation fan installed on the heat conduction structure. The heating box is also formed with a heat dissipation grille for the heat dissipation fan to discharge heat outward.

[0014] Furthermore: The number of heating modules is more than three.

[0015] Furthermore: An adjustment component is provided between two adjacent heating modules. The adjustment component includes a heating driving plate for installing the heating module, and a guide rail structure for the heating module to move horizontally is arranged along the length direction of the heating driving plate.

[0016] Furthermore: The guide rail structure includes a heating guide rail and a heating sliding seat installed on the heating plate. The heating sliding seat slidably cooperates with the heating guide rail.

[0017] Furthermore: The adjustment component further includes a linear module parallel to the heating guide rail.

[0018] Advantages 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 element 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 quality of cutting.

[0028] The present utility model will be described in detail below with reference to the accompanying drawings.

[0029] As Figures 1 - 3 shown, the laser heating vertical cutting mechanism includes a plurality of heating modules 1. The distance between two adjacent heating modules 1 can be adjusted. The heating module 1 includes a heating element and a cutting element. The heating element includes a heating box 11 and a laser heating element 12 installed in the heating box 11. The laser emitting head 13 is installed at the bottom of the heating box 11 and faces the material strip. The laser emitting head 13 is connected to the laser heating element 12; the cutting element includes a vertical cutting knife 16 located below the heating box 11. The vertical cutting knife 16 is longitudinally aligned with the laser emitting head 13, and the vertical cutting knife 16 is parallel to the moving direction of the material strip.

[0030] The entire raw material tape to be cut passes through the vertical cutting mechanism. At this time, the laser heating element 12 of the heating module 1 heats the area to be cut through the laser emitting head 13, making the area to be cut soften. Since the area heated by the laser emitting head 13 is small, after the entire raw material passes through the heating module 1, the heated area is a straight line. Cooperating with the vertical cutting knife 16 longitudinally aligned with the laser emitting head 13 to cut the heated area can reduce the generation of burrs and will not heat too many areas, ensuring the cutting quality.

[0031] The laser heating element 12 directly heats the sample stage or the sample using laser, with concentrated heating power, little impact on the vacuum, fast heating / cooling rate, and is especially suitable for an atmosphere with oxygen.

[0032] Preferably, there are two or more heating modules 1.

[0033] Preferably, there are three heating modules 1.

[0034] Set the corresponding number of heating modules 1 according to the cutting width of the tape and the number of segments after cutting.

[0035] The heating module 1 further includes a heating plate 10 for installing the heating box 11. A tool rest plate 14 is provided at the bottom of the heating plate 10. A driving tool rest 15 is installed on the tool rest plate 14, and the vertical cutting knife 16 is installed on the driving tool rest 15. During heating, the vertical cutting knife 16 installed on the driving tool rest 15 below cuts the entire raw material passing by, forming a strip-shaped tape.

[0036] Furthermore, a sliding installation groove 17 is longitudinally formed on the tool rest plate 14, and a sliding block 18 that slidably cooperates with the sliding installation groove 17 is formed on the driving tool rest 15. The height of the vertical cutting knife 16 can be adjusted through the cooperation of the sliding block 18 and the sliding groove. After adjusting to the required height, lock it with bolts to prevent it from being moved up and down, facilitating stable cutting of raw material sheets with different thicknesses.

[0037] Before cutting, the area where the laser emitting head 13 faces the raw material sheet cannot be seen with the naked eye, so the cutting area cannot be seen. For this, the heating plate 10 is also installed with a heating guide. The heating guide includes an infrared emitter 19 whose angle can be adjusted. The emitting end of the infrared emitter 19 and the laser emitting head 13 of the laser heating element 12 both face the cutting area of the tape. The red dot emitted by the emitting end of the infrared emitter 19 coincides with the heating area of the laser emitting head 13. The heating area can be observed according to the red dot emitted by the infrared emitter 19, and this heating area is also the cutting area, so the cutting area can also be observed, facilitating the observation of the cutting situation.

[0038] A heat dissipation module 2 for discharging the heat generated by the laser heating element 12 is provided inside the heating box 11; the heat dissipation module 2 includes a heat conduction structure 22 composed of heat dissipation fins 21 and a heat dissipation fan 23 installed on the heat conduction structure 22. The heating box 11 is also formed with a heat dissipation grille 24 for the heat dissipation fan 23 to discharge heat outwards. Since the laser heating element 12 generates a large amount of heat, the heat can be conducted through the heat dissipation fins 21 of the heat conduction structure 22 and discharged out of the heating box 11 through the heat dissipation fan 23 and the heat dissipation grille 24 to achieve heat dissipation.

[0039] An adjustment assembly is provided between two adjacent heating modules 1. The adjustment assembly includes a heating drive plate 25 for installing the heating module 1. The heating drive plate 25 is arranged along the length direction and is provided with a guide rail structure for the heating module 1 to move horizontally; through the guide rail structure, the heating drive plate 25 can slide horizontally, so that the horizontal position of the heating module 1 can be adjusted, which is convenient for cutting tape with different widths.

[0040] Specifically, the guide rail structure includes a heating guide rail 26 and a heating sliding seat 27 installed on the heating plate 10. The heating sliding seat 27 is slidably matched with the heating guide rail 26. The adjustment assembly further includes a linear module 28 parallel to the heating guide rail 26. The linear module 28 is connected to the heating sliding seat 27. Driven by the linear module 28, the heating sliding seat 27 moves along the heating guide rail 26 to achieve the position adjustment of the heating module 1.

[0041] In summary, it can be seen that the present utility model has the above-mentioned excellent characteristics, which can enhance the efficiency that has never been seen in the prior art during use and has practicality, becoming a product with extremely high practical value.

[0042] The above content is only the 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.
