Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting machines, and more particularly to a laser cutting machine for optical cable splitting boxes. Background Art

[0002] When an optical cable splitting box is cut, a laser cutting machine is often used for cutting. During the cutting process of some laser cutting machines, cooling is required through a coolant. Although the working efficiency during the cutting process is improved, the utilization efficiency of the coolant is not high, increasing the cutting cost during the cutting process.

[0003] Chinese Patent Publication No. CN214769761U discloses a laser cutting device for advertising light box processing, including a machine frame, two vertical plates, guide rails, a laser cutting machine body, a cleaning component, a cooling component, a cross plate and a water draining plate. The vertical plates are fixedly connected to the left and right sides of the top of the machine frame. The guide rails are installed between the inner sides of the vertical plates. The laser cutting machine body is slidably connected to the guide rails. The cleaning component is installed on the lower left side of the laser cutting machine body. The cooling component is installed on the lower right side of the laser cutting machine body. The cross plate is installed on the top of the vertical plates. The water draining plate is installed on the top of the machine frame.

[0004] The above solution realizes the recycling of the coolant. The above solution can also be applied to the cutting operation of the optical cable splitting box. However, during the cutting process, in order to avoid the laser from cutting the equipment itself, the equipment needs to be protected, and at the same time, the process parameters need to be optimized, such as controlling the laser power and monitoring the focal position, and pre-planning the movement trajectory. However, during cutting, the equipment needs to support the optical cable splitting box. When the laser cuts the optical cable splitting box, it needs to avoid the support points of the equipment. Otherwise, it will cut the equipment itself, resulting in the support points on the equipment affecting the cutting operation. During cutting, it is necessary to avoid the support points of the equipment, and the degree of freedom is relatively low. Summary of the Invention

When the first connecting unit is in a closed state, the lifting rod cannot be lifted or lowered in the lifting sleeve, and the support plate provides support for the plate.

The second electromagnet and the first electromagnet are respectively provided on both sides of the cutting head. There are two second electromagnets which are symmetrically arranged with respect to the first electromagnet. In the moving direction of the first electromagnet, the second electromagnet located behind the first electromagnet is energized, and the second electromagnet located in front of the first electromagnet is de-energized.

[0012] Preferably, the second communication unit includes a second communication sleeve, a second communication groove, a second lifting groove and a second communication block; The second communication sleeve is provided on one side of the lifting sleeve and communicates with the lifting sleeve; The second communication groove is horizontally and penetratingly provided in the second communication sleeve; The second lifting groove is vertically provided in the second communication sleeve and intersects with the second communication groove; The second communication block is vertically and slidably provided in the second lifting groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets a first electromagnet on one side of the cutting head and moves synchronously with the cutting head along the length direction of the placing table, and sets a lifting rod and a lifting sleeve at the lower part of the support plate, and sets a first connecting unit on one side of the lifting sleeve. When the first connecting unit is in a closed state, the lifting rod cannot be lifted and lowered in the lifting sleeve, and the support plate provides support for the plate. When the first electromagnet moves to the top of the first connecting unit, the first connecting unit opens under the magnetic force of the first electromagnet, and the support plate descends and disengages from the plate. When the cutting head passes through the support plate, the laser generated by the cutting head will not cut the support plate, while other support plates are still in a supporting state. When the cutting head leaves the top of the support plate, the hydraulic oil is re-injected into the lifting sleeve, so that the support plate rises again and supports the plate. In summary, the present invention not only ensures that the support plate can avoid cutting by the cutting head, but also ensures stable support for the plate, while avoiding the use of traditional independent cylinders to drive the support plate, reducing production costs and later maintenance costs.

[0017] 2. Since the vertical projection of the cutting head is located in the extension area of the first electromagnet in the width direction of the placement table, when the first electromagnet moves along the length direction of the placement table with the cutting head, when any end of the first electromagnet reaches directly above the first connected unit, the cutting head has not moved directly above the support plate corresponding to the first connected unit, so the support plate can be lowered in advance before the cutting head arrives. When the cutting head is directly above the support plate, when the cutting head cuts the plate, the laser cannot produce a cutting effect on the descending support plate. If one end of the first electromagnet is located directly above the first connected unit, the cutting head is also located directly above the support plate corresponding to the first connected unit. Although the first electromagnet can open the first connected unit and the support plate descends at this time, there is still a probability that the descending support plate will be cut by the laser. In summary, by making the vertical projection of the cutting head located in the extension area of the first electromagnet in the width direction of the placement table, it is ensured that the support plate has descended before the cutting head reaches the support plate, and the cutting effect of the cutting head on the support plate is completely avoided.

[0018] 3. First, the first electromagnet passes through the first communication unit, causing the first communication unit to open. The lifting sleeve discharges the hydraulic oil inside it. Subsequently, the cutting head reaches directly above the support plate. At this time, the support plate disengages from supporting the sheet material, and the cutting head will not cut the support plate during cutting. Then, the first electromagnet and the cutting head continue to move along the inherent direction. The second electromagnet located behind the first electromagnet moves directly above the second communication unit, and the second communication unit opens under the magnetic force of the second electromagnet. The water pump discharges the hydraulic oil in the liquid storage tank into the lifting sleeve through the second diversion pipe, causing the lifting rod located inside the lifting sleeve to rise, thereby realizing the upward reset of the support plate.

[0031] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners

[0032] Refer to Figures 1-3 、 Figure 5 、 Figure 6 and Figure 11 : The laser cutting machine for the optical cable splitting box includes a housing 1, a placing table 2 and a cutting head 11; The laser cutting machine further includes a support plate 22, a lifting rod 221, a first electromagnet 23, a lifting sleeve 24 and a first communication unit 25; A plurality of support plates 22 are arranged horizontally along the length direction of the placing table 2, and the upper ends of all the support plates 22 together form a support end surface for supporting the plate 3; The lifting rod 221 is vertically and fixedly arranged at the lower part of the support plate 22; The first electromagnet 23 is arranged on one side of the cutting head 11 and moves synchronously with the cutting head 11 along the length direction of the placing table 2; The lifting sleeve 24 is vertically arranged below the lifting rod 221, the lower end of the lifting rod 221 vertically extends into the lifting sleeve 24 and is slidably matched with the lifting sleeve 24, and hydraulic oil is arranged in the lifting sleeve 24; The first communication unit 25 is arranged on the side of the lifting sleeve 24 and is opened by magnetic force.

[0033] When the optical cable fiber distribution box is initially processed, the plate 3 is first cut into a preset shape by a laser cutting machine, and then the cut plate 3 is welded into shape to form the outer shape of the optical cable fiber distribution box. When cutting by laser, the plate 3 is usually placed on the supporting end surface composed of the supporting plates 22. A moving frame 21 for supporting all the supporting plates 22 is arranged below the supporting plates 22. The moving frame 21 drives all the supporting plates 22 to the working area of the cutting head 11. Since the supporting plates 22 of the existing laser cutting machine cannot move in the vertical direction, even if the supporting plates 22 can move in the vertical direction, the structure is relatively complex, and an independent cylinder is mostly used to control the lifting of the supporting plates 22, resulting in a high production cost. To reduce the cost, there are mainly four existing treatment methods, including: adjusting the cutting parameters, improving the material and structure of the supporting plates 22, adopting auxiliary process measures, and optimizing the cutting path and process planning. Among them, adjusting the cutting parameters requires adjusting the cutting power of the cutting head 11. If the power is reduced to avoid damaging the supporting plates 22, the cutting speed of the plate 3 will be too slow, and at the same time, the cutting quality will also decrease; if the material and structure of the supporting plates 22 are improved, by selecting high-temperature-resistant supporting plates 22 or increasing the thickness of the supporting plates 22, although the supportability of the supporting plates 22 can be ensured, the supporting plates 22 are still easily cut by the cutting head 11; if auxiliary process measures are adopted, such as using a protective gas or applying an anti-cutting coating, although the supporting plates 22 can be avoided from being cut to a certain extent, the use cost is high and the anti-cutting effect is limited; if the cutting path is optimized, by optimizing the moving path of the cutting head 11 and reducing the intersection points between the cutting head 11 and the supporting plates 22 during cutting, the supporting plates 22 can also be avoided from being cut to a certain extent, but it is still impossible to avoid the cutting head 11 passing by the supporting plates 22, and in order to consider that the supporting plates 22 are not cut, the path of the cutting head 11 is easily restricted during planning, resulting in the plate 3 not being fully utilized.

[0034] To avoid the above problems, the present invention still adopts the method of lifting the supporting plates 22 in the vertical direction to avoid the cutting of the cutting head 11. However, compared with the traditional driving method using an independent cylinder, the present invention reduces the production cost and maintenance cost and has higher popularity. The specific structure and working process of the present invention are as follows: The plate 3 is placed on the support end surface formed by the support plate 22. At this time, the support end surface is located on one side of the cutting area of the cutting head 11. Then, the support plate 22 is driven by the moving frame 21 along the length direction of the placement table 2 to the cutting area of the cutting head 11. After the moving frame 21 completely enters the cutting area of the cutting head 11, the moving frame 21 stops moving, and the cutting head 11 starts to cut the plate 3 according to the preset path. When the cutting head 11 moves along the length direction of the placement table 2, the first electromagnet 23 moves synchronously with the cutting head 11, and the first electromagnet 23 is started synchronously after the cutting head 11 runs. Before the cutting head 11 moves to the top of any support plate 22, the first electromagnet 23 first opens the first connecting unit 25 corresponding to the support plate 22, and the lifting rod 221 is on the support plate 2 2 slides into the lifting sleeve 24 under the action of gravity and squeezes out the hydraulic oil in the lifting sleeve 24. The squeezed hydraulic oil is discharged through the opened first connecting unit 25, so that the support plate 22 is lowered. When the cutting head 11 moves to the top of the support plate 22, since the support plate 22 is lowered in advance, the cutting head 11 will not cut the support plate 22 when cutting the plate 3. After the support plate 22 passes the support plate 22, the first connecting unit 25 is closed, and the discharged hydraulic oil is re-injected into the lifting sleeve 24, so that the lifting rod 221 drives the support plate 22 to rise and reset, ensuring that during the cutting process of the cutting head 11, there is always only one support plate 22 in the lowered state, so that the support plate 22 can avoid being cut by the cutting head 11 and ensure stable support for the plate 3.

[0035] A first electromagnet 23 is provided on one side of the cutting head 11, which moves synchronously with the cutting head 11 along the length direction of the placing table 2, and a lifting rod 221 and a lifting sleeve 24 are provided at the lower part of the support plate 22, and a first connecting unit 25 is provided on one side of the lifting sleeve 24. When the first connecting unit 25 is in a closed state, the lifting rod 221 cannot be lifted or lowered in the lifting sleeve 24, and the support plate 22 provides support for the plate 3. When the first electromagnet 23 moves to the top of the first connecting unit 25, the first connecting unit 25 is opened under the magnetic force of the first electromagnet 23, and the support plate 22 descends and disengages from the support for the plate 3. Subsequently, when the cutting head 11 passes through the support plate 22, the laser generated by the cutting head 11 will not cut the support plate 22, while the other support plates 22 are still in a supporting state. When the cutting head 11 leaves the top of the support plate 22, the hydraulic oil is re-injected into the lifting sleeve 24, so that the support plate 22 rises again and supports the plate 3. In summary, the present invention not only ensures that the support plate 22 can avoid cutting by the cutting head 11, but also ensures stable support for the plate 3, while avoiding the use of traditional independent cylinders to drive the support plate 22, thereby reducing production costs and subsequent maintenance costs.

[0036] Reference Figure 11: The first connection unit 25 includes a first connection sleeve 251, a connection groove, a lifting groove, and a first connection block 252; The first connection sleeve 251 is arranged on one side of the lifting sleeve 24 and is in communication with the lifting sleeve 24; The connection groove is horizontally and penetratingly formed in the first connection sleeve 251; The lifting groove is formed in the first connection sleeve 251, and the connection groove is in communication with the lifting groove; The first connection block 252 is vertically and slidably arranged in the lifting groove. The first connection block 252 can be magnetically attracted. A first through hole 2521 is horizontally and penetratingly formed in the first connection block 252. When the first connection block 252 moves up and down, the first through hole 2521 can be in communication with the connection groove.

[0037] When the cutting head 11 moves to directly above the support plate 22 along the length direction of the placing table 2, since the first electromagnet 23 moves synchronously with the cutting head 11 and the first electromagnet 23 is in a continuously energized state, the first electromagnet 23 is directly above the first connection sleeve 251 corresponding to the support plate 22. The first connection block 252 arranged in the lifting groove rises under the magnetic force of the first electromagnet 23. When the first connection block 252 rises to the highest position, the first through hole 2521 formed in the first connection block 252 is in communication with the connection groove, and the hydraulic oil in the lifting sleeve 24 can be freely discharged through the connection groove. At this time, the lifting rod 221 gradually slides into the lifting sleeve 24, so that the lifting rod 221 drives the support plate 22 to descend synchronously. Therefore, when the cutting head 11 moves to directly above the support plate 22, the support plate 22 disengages from the support of the plate 3, and the plate 3 is supported by other support plates 22, avoiding the cutting head 11 damaging the support plate 22 during the cutting process.

[0038] Refer to Figures 1-11 : The first electromagnet 23 is arranged in a horizontal state, and the vertical projection of the cutting head 11 is located in the extended area of the first electromagnet 23 in the width direction of the placing table 2.

[0039] Since the vertical projection of the cutting head 11 is located within the extension area of the first electromagnet 23 in the width direction of the placement table 2, during the process of the first electromagnet 23 moving along the length direction of the placement table 2 with the cutting head 11, when either end of the first electromagnet 23 reaches directly above the first communication unit 25, the cutting head 11 has not yet moved to directly above the support plate 22 corresponding to the first communication unit 25. Therefore, the support plate 22 can descend in advance before the cutting head 11 arrives. When the cutting head 11 is directly above the support plate 22 and cuts the sheet material 3, the laser cannot cut the descending support plate 22. If one end of the first electromagnet 23 is directly above the first communication unit 25 and the cutting head 11 is also directly above the support plate 22 corresponding to the first communication unit 25, although the first electromagnet 23 can open the first communication unit 25 at this time and the support plate 22 descends, there is still a probability that the descending support plate 22 will be cut by the laser. In summary, by making the vertical projection of the cutting head 11 located within the extension area of the first electromagnet 23 in the width direction of the placement table 2, it is ensured that the support plate 22 has descended before the cutting head 11 reaches it, completely avoiding the cutting action of the cutting head 11 on the support plate 22.

[0040] Refer to Figure 5 , Figure 9 and Figure 11 : A liquid storage tank 26 is provided below the lifting sleeve 24, and a first diversion pipe 261 communicating with the first communication unit 25 is provided on the liquid storage tank 26.

[0041] Since there are multiple support plates 22, there are also multiple first communication units 25. A first confluence pipe 262 is provided at the end of the first communication unit 25 far from the lifting sleeve 24. Both ends of the first diversion pipe 261 are respectively communicated with the first confluence pipe 262 and the liquid storage tank 26. When any one of the first communication units 25 is opened, the hydraulic oil in the lifting sleeve 24 corresponding to the first communication unit 25 will be discharged into the first confluence pipe 262 and flow into the liquid storage tank 26 through the first diversion pipe 261.

[0042] Refer to Figure 6 : The laser cutting machine further includes a second diversion pipe 263, a water pump 264, and a second communication unit 27; One end of the second diversion pipe 263 is provided on the liquid storage tank 26 and is communicated with the liquid storage tank 26; The water pump 264 is provided on the second diversion pipe 263; The second communication unit 27 is provided on one side of the lifting sleeve 24 and is communicated with the lifting sleeve 24. The second communication unit 27 is communicated with the liquid storage tank 26 through the second diversion pipe 263, and the second communication unit 27 and the first communication unit 25 are alternately opened.

[0043] When the first communication unit 25 is opened, the second communication unit 27 is in a closed state. The hydraulic oil in the lifting sleeve 24 is discharged into the liquid storage tank 26 through the second communication unit 27. After the cutting head 11 passes directly above the support plate 22, the first communication unit 25 loses the magnetic force and closes. Subsequently, the water pump 264 is started. The water pump 264 pumps out the hydraulic oil in the liquid storage tank 26 and discharges it into the lifting sleeve 24 through the second diversion pipe 263, causing the lifting rod 221 to drive the support plate 22 to rise, thereby realizing the reset of the support plate 22.

[0044] Refer to Figure 10 : The second communication unit 27 is opened under the magnetic force. The laser cutting machine further includes a second electromagnet 28. The second electromagnet 28 and the first electromagnet 23 are respectively arranged on both sides of the cutting head 11. There are two second electromagnets 28 which are symmetrically arranged with respect to the first electromagnet 23. In the moving direction of the first electromagnet 23, the second electromagnet 28 located behind the first electromagnet 23 is energized, and the second electromagnet 28 located in front of the first electromagnet 23 is de-energized.

[0045] The first electromagnet 23 first passes through the first communication unit 25, causing the first communication unit 25 to open. The lifting sleeve 24 discharges the hydraulic oil inside it. Subsequently, the cutting head 11 reaches directly above the support plate 22. At this time, the support plate 22 disengages from the support of the sheet 3, and the cutting head 11 will not cause a cutting effect on the support plate 22 during cutting. Subsequently, the first electromagnet 23 and the cutting head 11 continue to move along the inherent direction. The second electromagnet 28 located behind the first electromagnet 23 moves directly above the second communication unit 27. The second communication unit 27 is opened under the magnetic force of the second electromagnet 28. The water pump 264 discharges the hydraulic oil in the liquid storage tank 26 into the lifting sleeve 24 through the second diversion pipe 263, causing the lifting rod 221 located in the lifting sleeve 24 to rise, thereby realizing the upward reset of the support plate 22.

[0046] Refer to Figure 10 : The second communication unit 27 includes a second communication sleeve 271, a second communication groove 2711, a second lifting groove 2712 and a second communication block 272; The second communication sleeve 271 is arranged on one side of the lifting sleeve 24 and is communicated with the lifting sleeve 24; The second communication groove 2711 is horizontally and penetratingly opened on the second communication sleeve 271; The second lifting groove 2712 is vertically opened in the second communication sleeve 271 and intersects with the second communication groove 2711; The second communication block 272 is vertically and slidably arranged in the second lifting groove 2712. A second through hole 2721 is horizontally and penetratingly opened on the second communication block 272. When the second communication block 272 moves up and down, the second through hole 2721 can be communicated with the second communication groove 2711.

[0047] The working principle of the second communication unit 27 is the same as that of the first communication unit 25. Before the second electromagnet 28 moves directly above the second communication unit 27, the second communication block 272 is located at the bottom of the second lifting groove 2712, and the second through hole 2721 is disconnected from the second communication groove 2711. When the second electromagnet 28 moves directly above the second communication unit 27, the second communication block 272 rises, and the second through hole 2721 communicates with the second communication groove 2711. At this time, the water pump 264 is started, and the water pump 264 pumps hydraulic oil into the lifting sleeve 24 through the second diversion pipe 263.

[0048] Refer to Figure 6 : The second communication unit 27 includes a one-way valve 273. The one-way valve 273 is arranged between the second communication sleeve 271 and the lifting sleeve 24, and the hydraulic oil in the liquid storage tank 26 flows into the lifting sleeve 24 through the one-way valve 273.

[0049] By setting the one-way valve 273, when the second communication unit 27 is opened and the water pump 264 is not started in time, the support plate 22 will not further descend, which improves the reset speed of the support plate 22.

[0050] Refer to Figure 2 and Figure 4 : The laser cutting machine further includes a detection unit 29. The detection unit 29 includes a roller 291 and a direction sensor 292; The roller 291 is arranged above the cutting head 11 and moves synchronously with the cutting head 11 along the length direction of the placement table 2. The roller 291 is in rolling cooperation with the top of the housing 1; The direction sensor 292 is arranged at the end of the roller 291.

[0051] The direction sensor 292 detects the rolling direction of the roller 291, thereby judging the moving direction of the cutting head 11, and finally judging which second electromagnet 28 is located behind the first electromagnet 23, and energizing the second electromagnet 28 located behind the first electromagnet 23.

[0052] Refer to Figure 4 : The detection unit 29 further includes a mounting bracket 293, a spring 294 and a driving bracket 295; The mounting bracket 293 is arranged below the roller 291, and the roller 291 is rotatably arranged on the mounting bracket 293; The spring 294 is arranged vertically below the mounting bracket 293, and the upper end of the spring 294 is fixedly connected to the mounting bracket 293; The driving bracket 295 is arranged at the lower end of the spring 294 and is fixedly connected to the spring 294, and the cutting head 11 is arranged on the driving bracket 295.

[0053] The spring 294 is always in a compressed state, providing elastic force for the mounting bracket 293 through the spring 294, so that the roller 291 can always press on the top of the housing 1, ensuring the stable detection of the direction sensor 292.

[0054] Working principle: Place the sheet 3 on the supporting end face formed by the supporting plate 22. At this time, the supporting end face is located on one side of the cutting area of the cutting head 11. Subsequently, the supporting plate 22 is driven by the moving frame 21 along the length direction of the placing table 2 into the cutting area of the cutting head 11. After the moving frame 21 completely enters the cutting area of the cutting head 11, the moving frame 21 stops moving, and the cutting head 11 starts to cut the sheet 3 according to a preset path. When the cutting head 11 moves along the length direction of the placing table 2, the first electromagnet 23 moves synchronously with the cutting head 11, and the first electromagnet 23 is started synchronously after the cutting head 11 operates. Before the cutting head 11 moves directly above any supporting plate 22, the first electromagnet 23 opens the first communication unit 25 corresponding to the supporting plate 22. The lifting rod 221 slides into the lifting sleeve 24 under the gravity of the supporting plate 22 and squeezes out the hydraulic oil in the lifting sleeve 24. The squeezed hydraulic oil is discharged through the opened first communication unit 25, so that the supporting plate 22 descends. When the cutting head 11 moves directly above the supporting plate 22, since the supporting plate 22 descends in advance, the cutting head 11 will not cut the supporting plate 22 when cutting the sheet 3. After the supporting plate 22 passes by the supporting plate 22, the first communication unit 25 is closed, and the discharged hydraulic oil is re-injected into the lifting sleeve 24, so that the lifting rod 221 drives the supporting plate 22 to rise and reset, ensuring that during the cutting process of the cutting head 11, only one supporting plate 22 is in a descending state at all times, realizing that the supporting plate 22 can avoid being cut by the cutting head 11 and ensure the stable support of the sheet 3.
