Description

Technical Field

[0002] The diamond wire cutting machine is a common device used for cutting metal, and the I-spool is a commonly used component on the metal wire cutting machine. The I-spool is mainly used for winding metal wire. After the cutting equipment has been used for a period of time, the diamond wire busbar used for cutting will age and wear out, and the scrap metal wire wound on the I-spool needs to be recycled. At present, many manufacturers will manually cut the scrap metal wire on the I-spool in order to quickly recycle the I-spool and scrap metal wire; however, with the increase in cutting operations, the amount of scrap metal wire is getting larger and larger, and the manual cutting method is inefficient and difficult to meet the current recycling volume. At the same time, the I-spool is easily damaged during the cutting process, which increases the scrapping of the I-spool and increases the loss of the production line. In addition, during the winding process of the diamond wire busbar, there are cases of wire knotting. The existing method of manually cutting miscellaneous wires (wire knots) is cumbersome and the cutting process is inefficient. Utility Model Content

[0033] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0034] As described in the background technology, the manual cutting and recycling method of scrap metal wire in the prior art is relatively inefficient. Therefore, the present application creatively proposes a laser cutting device, which includes a frame, a first drive component, a mounting platform, a second drive component and a laser module. The second direction is perpendicular to the first direction. When cutting the scrap metal wire, the I-shaped wheel with the scrap metal wire wrapped around it is installed on the mounting platform to fix the I-shaped wheel. The mounting platform is then driven to move by the first drive component so that the laser module is aligned with the initial cutting position of the scrap metal wire. When cutting starts, the mounting platform and the I-shaped wheel are driven to move back and forth along the first direction by the first drive component. , so that the laser module can quickly and fully cut the scrap metal wire along the first direction. At the same time, during the cutting process, as the thickness of the scrap metal wire gradually becomes smaller, the second driving component can be used to drive the laser module to approach the scrap metal wire along the second direction, thereby ensuring that the laser module is focused on the scrap metal wire to ensure the cutting effect and improve the cutting efficiency. Compared with the prior art, the present application moves the I-wheel through the first driving component to achieve rapid cutting of the scrap metal wire along the axial direction of the I-wheel, and moves the laser module through the second driving component to achieve rapid cutting of the scrap metal wire along the radial direction of the I-wheel, ultimately achieving rapid cutting of the scrap metal wire and improving the cutting efficiency.

[0035] The present application will be described in detail below through specific embodiments.

[0036] Reference Figure 1 and Figure 2 As shown, the laser cutting device includes a frame 1, a first drive component 2, a mounting platform 3, a second drive component 4 and a laser module 5, wherein: the mounting platform 3 is configured to mount the I-shaped wheel 7; the first drive component 2 is provided on the frame 1, and is configured to drive the mounting platform 3 to reciprocate along a first direction; the laser module 5 is configured to cut the metal wire wound around the I-shaped wheel 7; the second drive component 4 is provided on the frame 1, and is configured to drive the laser module 5 to reciprocate along a second direction, and the first direction is a horizontal direction, and is the axial direction of the I-shaped wheel 7, and the second direction is a vertical direction, and is the radial direction of the I-shaped wheel 7.

[0037] It should be noted that when the scrap metal wire is wound around the spool 7, it forms a cylindrical structure. In this case, the scrap metal wire can be considered as a whole and defined as having an axial direction and a radial direction. The axial direction of the scrap metal wire is parallel to the axial direction of the spool 7, and the radial direction of the scrap metal wire is parallel to the radial direction of the spool 7. When cutting the scrap metal wire, it is necessary to completely cut along both the radial and axial directions to achieve complete cutting of the scrap metal wire.

[0038] Specifically, when preparing to cut the scrap metal wire, the I-shaped wheel 7 with the scrap metal wire wound thereon is first installed on the mounting platform 3 by manual or mechanical means to ensure that the I-shaped wheel 7 remains stable during the cutting process; when cutting the scrap metal wire, the first driving component 2 is first started to drive the mounting platform 3 and the I-shaped wheel 7 to move in the first direction, so that the laser module 5 is aligned with the initial cutting position of the scrap metal wire, and then the laser module 5 is started to cut the scrap metal wire. At the same time, the first driving component 2 drives the scrap metal wire to move in the first direction to achieve rapid and sufficient cutting of the scrap metal wire in its axial direction; during the cutting process, as the thickness of the scrap metal wire (i.e., in the radial direction) gradually decreases, the laser module 5 can be driven by the second driving component 4 to approach the scrap metal wire in the second direction to ensure that the laser module 5 focuses on the scrap metal wire, improve the cutting effect, and improve the cutting efficiency, thereby achieving rapid cutting of the scrap metal wire in its radial direction, so that the scrap metal wire is quickly and fully cut in its axial and radial directions, and ultimately improving the cutting efficiency of the scrap metal wire.

[0039] It should also be noted that the user can set the initial cutting position of the scrap metal wire as needed, as long as the scrap metal wire can be completely cut. In this embodiment, the initial cutting position of the scrap metal wire is one end face of the scrap metal wire (the axial direction of the scrap metal wire). The laser module 5 can effectively cut scrap metal wire of a certain thickness (the radial direction of the scrap metal wire) during cutting. The laser module 5 cuts the scrap metal wire along a first direction (i.e., a direction parallel to the axial direction of the I-shaped wheel 7) until it cuts to the other end face of the scrap metal wire, completing an effective cut. Then, the second drive component 4 drives the laser module 5 to a certain distance close to the scrap metal wire and cuts along the first direction until it returns to the original end face of the scrap metal wire, completing an effective cut. The remaining cutting process is consistent with the above until the scrap metal wire is completely cut.

[0040] In this embodiment, the frame 1 is in the shape of a rectangular parallelepiped as a whole.

[0041] In some examples, the first driving member is a horizontally arranged screw module, the mounting platform 3 is installed on the moving part of the first driving component 2, the second driving component 4 is a vertically arranged screw module, and the laser module 5 is installed on the moving part of the second driving component 4; wherein the cutting axis of the laser module 5 intersects vertically with the travel axis of the first driving component 2 in a vertical plane.

[0042] Specifically, by arranging the first drive assembly 2 and the mounting platform 3 horizontally, the cut scrap metal wire is spread flat on the mounting platform 3 with the cutting line as the centerline, in a direction away from the axis of the spool 7, thereby reducing the scrap metal wire from scattering due to gravity and other factors. The second drive assembly 4 is arranged vertically, so that the laser module 5 can cut the highest vertical section of the scrap metal wire, allowing both ends of the cut scrap metal wire to fall simultaneously on the mounting platform 3, keeping the two cut surfaces of the scrap metal wire as flush as possible. Simultaneously, configuring the first drive assembly 2 and the second drive assembly 4 as a screw assembly can improve the accuracy of the movement distance between the laser module 5 and the spool 7, thereby improving cutting accuracy and reducing inadvertent cutting of the end face of the spool 7.

[0043] In addition, when a wire knot occurs during the winding process of the diamond wire busbar, the laser cutting device of the present application can be used to quickly cut off the stray wires (the knotted parts) and then restart the wire drawing process, thereby improving the utilization rate of the production line.

[0044] In this embodiment, the laser module 5 is a fiber laser generator, which has the characteristics of flexibility, stability and high efficiency. It can improve the cutting efficiency of scrap metal wire and reduce damage to the I-shaped wheel 7 to protect the I-shaped wheel 7.

[0045] In addition, it should be noted that, referring to Figure 2 As shown, the surface of the spool 7 used in this embodiment is provided with a laser reflective layer 71. When the fiber laser irradiates the laser reflective layer 71, the fiber laser is reflected, protecting the spool 7 from damage. Specifically, the laser reflective layer 71 is U-shaped to fully protect the spool 7. During cutting, the spool 7 is adjusted so that the laser reflective layer 71 is vertically upward. The scrap metal wire is then cut at the position directly corresponding to the laser reflective layer 71 in the vertical direction. This ensures that the fiber optic cable is aligned with the laser reflective layer 71 after cutting the scrap metal wire.

[0046] Furthermore, in some examples, the mounting platform 3 includes a limiting structure 31 and a supporting plate 32 configured to support the spool 7 , the limiting structure 31 is mounted on the supporting plate 32 , and a limiting space 311 for limiting the movement of the spool 7 is provided in the limiting structure 31 .

[0047] In this embodiment, the supporting plate 32 is a square thin plate and is fixed to the moving part of the first drive assembly 2 by a locking structure such as bolts; of course, the supporting plate 32 can also be a plate structure of other shapes, such as an L-shaped plate, a Z-shaped plate, etc., as long as it can meet the requirements of stably supporting the I-shaped wheel 7 and taking over the scattered scrap metal wire after cutting.

[0048] In some examples, the limiting structure 31 includes two limiting plates 312 spaced apart along a first direction, and the two limiting plates 312 are arranged relative to each other to form a limiting space 311 for limiting the movement of the I-wheel 7; the inner side of at least one limiting plate 312 is provided with a positioning column 314 for adapting to be inserted into the I-wheel 7 to position the I-wheel 7 for subsequent cutting.

[0049] Furthermore, a positioning hole is provided on the end face of the spool 7 , and at least three positioning rods 313 for inserting into the positioning holes are provided on the limiting plate 312 ; wherein the positioning rods 313 are arranged according to a preset rule to limit the placement state of the spool 7 .

[0050] It should be noted that in this embodiment, the preset rule is to distribute the positioning rods 313 along the circumference of the positioning column 314 so that the positioning rods 313 correspond one-to-one with the three positioning holes set on the end surface of the spool 7. In addition, the at least three positioning rods 313 utilize the principle of three points forming a circle to restrict the placement of the spool 7 to only one state. Therefore, the position of the laser reflective layer 71 can be restricted by adjusting the relative position of the positioning rods 313 and the laser reflective layer 71. Therefore, after the spool 7 is positioned by the positioning rods 313, the laser reflective layer 71 can only remain directly opposite the laser module 5.

[0051] Specifically, the limiting plate 312 can be fixedly mounted on the supporting plate 32, or multiple limiting plate 312 mounting positions can be provided on the supporting plate 32 as needed to accommodate spools 7 of varying sizes. Alternatively, the limiting plate 312 can be slidably connected to the supporting plate 32 and secured with a locking structure such as a bolt. When securing the spool 7, the two opposing limiting plates 312 are used to constrain the spool 7, ensuring that the spool 7 remains stable during cutting of the scrap wire. Furthermore, the positioning rod 313, inserted into the positioning hole of the spool 7, further secures the spool 7 and enhances its installation stability.

[0052] Further, in some examples, reference Figure 1 and Figure 3 As shown, positioning columns 314 are provided on the inner sides of the two limit plates 312 to form a cooling space 9 between the I-shaped wheel 7; the laser cutting device also includes an input pipe 91 and an output pipe 92, and the input pipe 91 and the output pipe 92 both pass through one of the two positioning columns 314 to communicate with the cooling space 9. The input pipe 91 is configured to transport the cooling medium into the cooling space 9, and the output pipe 92 is configured to output the heated cooling medium to the cooling space 9.

[0053] It should be noted that the cooling medium can be cooling water or cold air, or other fluids that can achieve heat exchange and will not corrode the inner surface of the spool. In this embodiment, cooling water is selected as the cooling medium.

[0054] It is understood that the input pipe 91 and the output pipe 92 can be arranged on the same side, that is, both pass through the same positioning post 314 to communicate with the cooling space 9; the input pipe 91 and the output pipe 92 can also be arranged on opposite sides, that is, the input pipe 91 communicates with the cooling space 9 through one of the two positioning posts 314, and the output pipe 92 communicates with the cooling space 9 through the other of the two positioning posts 314. In this embodiment, the input pipe 91 and the output pipe 92 are arranged on the same side.

[0055] Optionally, the input pipe 91 and the output pipe 92 are arranged in sequence along the vertical direction. When transporting cooling water, cooling water with a certain pressure can be input into the cooling space 9 so that the cooling water can be sprayed onto the upper inner surface of the I-wheel 7; at the same time, the input pipe 91 is arranged above the output pipe 92 so that the cooling water falls on the lower inner surface of the I-wheel 7 based on gravity, thereby achieving full contact with the inner surface of the I-wheel 7, so as to fully exchange heat with the I-wheel 7, thereby reducing the temperature of the embedded parts of the I-wheel 7 and reducing the heating damage of the laser to the embedded parts of the I-wheel 7.

[0056] In some examples, reference Figure 3 As shown, the I-shaped wheel 7 is provided with seals 93 on both sides of its own axial direction to interference fit with the positioning column 314, thereby improving the sealing of the cooling space 9, preventing the leakage of the cooling medium, and improving the heat exchange efficiency of the cooling medium.

[0057] In this embodiment, the sealing member 93 is a sealing ring.

[0058] In some examples, the laser cutting device includes a blowing and suction assembly 6 , which is disposed on the frame 1 and configured to blow air toward the mounting platform 3 and / or suck air from the mounting platform 3 .

[0059] It is understood that, depending on actual needs, the blowing and suction assembly 6 can blow air onto the mounting platform 3 alone to remove the heat generated by laser cutting. The blowing and suction assembly 6 can also absorb air from the mounting platform 3 alone, thereby removing the heat generated during the cutting of the scrap metal wire and preventing the heat from damaging the spool 7.

[0060] In this embodiment, the blowing and suction assembly 6 both blows air onto the mounting platform 3 and draws air from the mounting platform 3. During the laser cutting process, the blowing and suction assembly 6 operates synchronously, allowing the heat on the scrap metal wire (scrap diamond wire busbar) to be quickly removed by the blown cold air, thereby cooling the scrap metal wire and preventing the laser heat on the scrap metal wire from damaging the high-performance plastic material on the spool. At the same time, the blowing and suction assembly 6 also draws away the heat from the mounting platform 3, further preventing the heat generated by the wire cutting from damaging the spool 7.

[0061] It should be noted that the blowing and suction devices can be the same device or different devices. The blowing pressure and temperature are different from the suction pressure and temperature so that both can act on the airflow at the mounting platform 3 at the same time.

[0062] Furthermore, the blowing and suction assembly 6 includes at least two suction parts arranged above the mounting platform 3, and the two suction parts form a group and are symmetrically distributed about the axis of the I-shaped wheel 7, thereby achieving uniform cooling of the scrap metal wire on the axial cutting line of the scrap metal wire, and preventing the heated scrap metal wire from damaging the I-shaped wheel 7.

[0063] In this embodiment, the air suction element is a wedge-shaped air knife to adapt to the narrow radial cutting path of the scrap metal wire, improving the cooling effect. Two air suction elements are installed on both sides of the laser module 5 along the second direction. They follow the rise and fall of the laser module 5, moving away from or closer to the scrap metal wire, thereby ensuring effective cooling.

[0064] Furthermore, in some examples, the blowing and suction assembly 6 also includes a recovery pipe and a storage container, the recovery pipe having a first end and a second end, the first end being connected to the suction member, and the second end being connected to the storage container, so as to recover the short wires generated when cutting the waste wire into the storage container.

[0065] Specifically, when the suction piece absorbs the air flow around the waste metal wire, the broken wire generated during the wire cutting process enters the suction piece along with the air flow, and then transfers it into the recovery pipe until it enters the storage container, preventing the broken wire from being scattered in the external environment.

[0066] In some examples, reference Figure 1 As shown, the laser cutting device further includes a control component 8, which includes a controller disposed inside the frame and an operation panel 81 disposed on the mounting platform, so as to facilitate the operator to control the laser cutting device.
