Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to a full-protection laser tube cutting machine. Background Art

[0002] The chuck-type laser tube cutting machine has the characteristics of high precision and high efficiency, and is especially suitable for cutting large tubes. It is generally composed of a base frame, multiple chucks, and a laser cutting assembly. The multiple chucks are used to clamp the tubes and push the tubes toward the laser cutting assembly. In addition, in order to improve the support effect for large tubes, a centering follower mechanism is generally provided to support the tubes and ensure that the tubes do not shake during rotation. As we all know, the higher the degree of automation, the more transmission structures are involved in the laser tube cutting machine. The exposed transmission structure is easy to cause harm to the operator, and the high-intensity laser beam emitted by the laser cutting assembly may also cause harm to the operator. Although some existing laser tube cutting machines are equipped with some basic protective measures, the protection range is limited and cannot completely cover areas where accidental touch may occur.

DETAILED DESCRIPTION

[0031] The present invention provides a fully protected laser tube cutting machine. To make the objectives, technical solutions, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0032] See also Figure 1 and Figure 2 The present invention provides a fully protected laser tube cutting machine, comprising a side-hanging bed 1, a gantry 16 arranged on the side-hanging bed 1, a laser cutting assembly 2 arranged on the gantry 16, and a first chuck structure 41, a second chuck structure 42 and a third chuck structure 43 arranged to slide in sequence along the Y-axis direction of the side-hanging bed 1; a plurality of mounting side seats 13 are arranged on the left side of the side-hanging bed 1, and a centering follower mechanism 3 is arranged on the mounting side seat 13, and the centering follower mechanism 3 is used to clamp the pipe so that the pipe is centered, and the external arrangement of the centering follower mechanism 3 There is a centering follower mechanism protection structure 5; a plurality of reinforced side seats 14 are provided on the right side of the side-hanging bed 1, and a blanking mechanism is provided between the reinforced side seats 14, and the blanking mechanism is used to blank the pipe after cutting; a support seat 15 is provided between the adjacent mounting side seats 13 and the reinforced side seats 14, and the front side of the gantry 16 is fixedly connected to the support seat 15; the support seat 15 and the gantry 16 are surrounded by a protective box 6, and the protective box 6 is used to enclose the laser cutting assembly 2 inside it; please refer to Figure 4 and Figure 5 The front of the protective box 6 is provided with a material unloading area 611 for unloading pipes, and the left and right sides of the protective box 6 are respectively provided with avoidance areas 612 for the second chuck structure 42 and the third chuck structure 43 to pass through; Figure 1 A first chuck protection structure 44 is provided on the outside of the first chuck structure 41 , a second chuck protection structure is provided on the outside of the second chuck structure 42 , and a third chuck protection structure 46 is provided on the outside of the third chuck structure 43 .

[0033] The pipe to be cut is loaded onto the centering follower mechanism 3, and then the centering follower mechanism 3 centers the pipe and lifts the pipe to be coaxial with the first chuck structure 41, the second chuck structure 42 and the third chuck structure 43. The pipe will be clamped by the first chuck structure 41 and the second chuck structure 42 and pushed toward the laser cutting assembly 2 by the first chuck structure 41 to realize cutting feeding. Therefore, the avoidance area 612 is opened on the left and right sides of the protective box 6 to avoid the corresponding chuck structure, and the cut-off pipe section will be clamped by the third chuck structure 43 and unloaded with the cooperation of the unloading mechanism. Furthermore, because the second chuck structure 42 can move relative to the laser cutting assembly 2, when there is any residual material left in the pipe, the laser cutting head of the laser cutting assembly 2 is pointed vertically downward, narrowing the distance between the second chuck structure 42 and the laser cutting assembly 2, and then the remaining pipe is cut straight, thereby reducing the amount of residual material. The residual material / short material is then discharged from the discharge area 611, which can be used to place a discharge box for receiving materials. The discharge area 611 also facilitates the operator to enter the interior of the protective box 6 from this location when the laser pipe cutting machine is not in operation.

[0034] The above-mentioned laser tube cutting machine, through the provision of a centering follower mechanism protection structure 5, multiple chuck protection structures, and a protection box 6, encloses the centering follower mechanism 3, the corresponding chuck drive mechanism, the gantry 16 and the laser cutting assembly 2 inside the corresponding structure. When the operator is located outside the protective structures and the protection box 6, it can effectively prevent the drive mechanisms from touching the operator, and can effectively prevent the scattering and reflection of the laser during the cutting process, thereby preventing the laser from escaping and causing harm to the operator.

[0035] Specifically, the laser cutting component 2 uses various driving mechanisms to enable the laser cutting head to move back and forth along the X-axis and Z-axis directions. The laser cutting component 2 cooperates with three chuck structures that can be pushed along the Y-axis direction to achieve multi-directional cutting of the pipe. The laser cutting component 2 and the laser cutting head are both existing technologies and will not be repeated here.

[0036] More specifically, the centering follower mechanism protection structure 5, the protection box 6, etc. are all made of sheet metal parts, and related components such as air source processing can be centrally installed thereon for easy adjustment.

[0037] See also Figure 3-Figure 5In some embodiments, a front protective curtain 68 is provided in front of the protective box 6, and the front protective curtain 68 is used to block the unloading area 611; side protective curtains 69 are provided on the left and right sides of the protective box 6, respectively, and the side protective curtains 69 are used to block the avoidance area 612. The protective box 6 cooperates with the front protective curtain 68 and the side protective curtains 69 to achieve all-round laser protection. Moreover, the front protective curtain 68 has a lower manufacturing cost than a protective door, and it is more convenient to enter and exit the protective box 6. Specifically, the front protective curtain 68 and the side protective curtain 69 are preferably black fireproof curtains. Black has a strong shielding ability against the light generated by the laser, and the fireproof curtains are made of fireproof materials to prevent the fireproof curtains from melting due to heat, thereby extending the service life of the fireproof curtains.

[0038] See also Figure 4 and Figure 6 In some embodiments, the lower surface of the protective case 6 is provided with a first clip 63 and a second clip 64. The upper portions of the front protective curtain 68 and the upper portions of the side protective curtains 69 are clamped between the first clip 63 and the second clip 64 via fasteners. In actual use, the first clip 63, the second clip 64, and the front protective curtain 68 or the side protective curtain 69 are modularly designed. During assembly, this modular assembly can be simply installed in the corresponding position of the protective case 6. When the front protective curtain 68 or the side protective curtain 69 needs to be replaced, the corresponding locking members are removed and replaced with new ones, making assembly and disassembly convenient. In addition, the first clip 63 and the second clip 64 cooperate with fasteners to clamp and secure the upper portions of the front protective curtain 68 and the side protective curtain 69. This connection ensures that the front protective curtain 68 and the side protective curtain 69 remain stably attached to the protective case 6 during use.

[0039] See also Figure 6 , see Figure 3 In some embodiments, the fasteners are screws / bolts / screws and nuts (not shown). The first and second clips 63, 64 are provided with multiple through-holes 631 extending along their lengths, and the fasteners are positioned within the corresponding through-holes 631. The front protective curtain 68 and the side protective curtains 69 are both made of a soft material. Therefore, the screws / bolts / screws can be inserted through the corresponding through-holes 631 and then passed through both sides of the front and side protective curtains 68, 69. Finally, the screws / bolts / screws are clamped in the gap between the first and second clips 63, 64 using nuts to complete assembly. The modular structure can then be installed in the corresponding position on the protective box 6.

[0040] See also Figure 3 and Figure 4In some embodiments, a viewing window 613 is provided in the front of the protective box 6, and a transparent window 614 is provided within the viewing window 613. During the laser cutting operation, the operator needs to observe the situation within the cutting area in real time to promptly understand the cutting progress, the status of the pipe cutting, and whether there are any abnormalities. The provision of the transparent window 614 enables the operator to clearly observe the operating conditions of the laser cutting assembly 2 and other components within the protective box 6 through the viewing window 613 while ensuring their own safety, ensuring smooth cutting operations while avoiding the risk of injury from direct exposure to laser radiation. Specifically, the transparent window 614 is preferably made of radiation-proof glass.

[0041] See also Figure 4 In some embodiments, the protective housing 6 includes a lower housing 61 and an upper housing 62 connected to the lower housing 61. The length of the upper housing 62 along the Y-axis is shorter than that of the lower housing 61 along the Y-axis. The upper housing 62 is used to accommodate the drive mechanism of the laser cutting assembly 2. Because the cutting area covers a wide range, the volume of the lower housing 61 needs to be designed to be larger. However, the active area of ​​the laser cutting assembly 2 and the Z-axis drag chain mounted on the gantry 16 is relatively small, so the volume of the upper housing 62 is designed to be smaller. This configuration avoids wasted space and makes the spatial layout and volume of the protective housing 6 more reasonable.

[0042] See also Figure 3-Figure 5 In some embodiments, a baffle 65 is further provided between the side-hanging bed 1 and the gantry 16. The baffle 65 is located within the avoidance area 612, and the lower surface of the baffle 65 is fixedly connected to the upper surface of the support seat 15. In actual application, the lower surface of the front portion of the gantry 16 is fixedly connected to the support seat 15, and the lower surface of the rear portion is fixedly connected to the side-hanging bed 1. Since there is a certain distance between the support seat 15 and the laser cutting assembly 2, a baffle 65 is provided. The baffle 65 cooperates with the protective box 6 to further reduce the escape of the laser in the cutting area. In order to further enhance the shielding effect of the baffle 65 on the laser, an arc-shaped groove that matches the curvature of the lower portion of the chuck is further provided on the upper portion of the baffle 65.

[0043] See also Figure 4 and Figure 5In some embodiments, the support base 15 is hollow. An exhaust duct 66 is disposed between the support base 15 and the side-mounted bed 1. The exhaust duct 66 passes through the left and right sides of the support base 15 and the front and rear sides of the side-mounted bed 1. The air inlet of the exhaust duct 66 communicates with the inner cavity of the protective box 6. The exhaust duct 66 is connected to an exhaust device. This arrangement can quickly remove dust generated within the cutting area, protecting the working environment. Furthermore, the exhaust duct 66 is relatively short, fully utilizing the position of the side-mounted bed 1 and the support base 15, resulting in a more rational design.

[0044] See also Figure 4 In some embodiments, a shield 67 is provided on the side wall of the support base 15 facing the cutting area. The shield 67 is used to house the air inlet of the exhaust pipe 66 within the shield 67. The shield 67 also has an exhaust hole 671. The shield 67 covers the air inlet of the exhaust pipe 66, effectively directing the smoke and exhaust gas generated during the laser cutting process toward the exhaust hole 671. Furthermore, the cutting area also involves the unloading area 611. Therefore, the shield 67 also prevents short pipes or tailings from falling and directly contacting the exhaust pipe 66, thereby damaging the exhaust pipe 66.

[0045] See also Figure 4 In some embodiments, the sidewall of the shield 67 is configured as an inclined surface; the inclined surface faces upward, and the ventilation holes 671 are provided on the inclined surface. The inclined surface can guide the tailings that fall onto the shield 67, thereby preventing the tailings from falling onto the shield 67 and blocking the ventilation holes 671 on the shield 67, thereby affecting the ventilation effect.

[0046] See also Figure 2 and Figure 8 In some embodiments, a distance measuring mechanism 411 is provided on the outside of the first chuck structure 41, and the distance measuring mechanism 411 is used to measure the distance from the left end of the pipe on the centering follower mechanism 3 to the feeding material; please refer to Figure 7 and Figure 8The first chuck protection structure 44 includes a first protective cover 441 for enclosing the first Y-axis side plate 81, the first Y-axis side plate drive mechanism 82, the first chuck drive mechanism, and the distance measuring mechanism 411. The first protective cover 441 has a sidewall facing the laser cutting assembly 2 that is provided with a clearance hole 442 for circumventing the distance measuring mechanism 411. In this embodiment, the first Y-axis side plate drive mechanism 82 can be driven by a motor, gear, and rack. The first chuck structure 41 is fixedly connected to the first Y-axis side plate 81, so that the first Y-axis side plate 81 can drive the first chuck structure 41 to reciprocate along the length of the side-hanging bed 1. In actual application, the pipe loaded onto the centering follower mechanism 3 needs to be driven by the first Y-axis side hanging plate driving mechanism 82 to move the first chuck structure 41 toward the left end of the pipe. According to the program setting, after the first chuck structure 41 moves to the set position, it is extended to the right by the distance measuring mechanism 411 and touches the left end of the pipe to measure the distance from the first chuck structure 41 to the left end of the pipe, so that the first chuck structure 41 can be firmly clamped to the left end of the pipe to avoid the occurrence of empty clamping of the pipe. Specifically, the distance measuring mechanism 411 is a cylinder, a movable plate, and a stroke sensor. By extending the output end of the cylinder, the movable plate is extended from the avoidance hole 442, and the moving stroke of the movable plate is measured by the stroke sensor. The above-mentioned first chuck protection structure 44 can enclose the first Y-axis side hanging plate driving mechanism 82 and the first chuck driving mechanism inside it to avoid exposure of the driving mechanism.

[0047] In some embodiments, beam sensors (not shown) are mounted on the front and rear sidewalls of the gantry 16. These sensors, in conjunction with the distance-measuring mechanism 411, sense the position of the right end of the pipe loaded onto the centering follower mechanism 3 and measure the length of the pipe to be cut. After being gripped by the first chuck structure 41, the pipe is pushed to the right until the right end of the pipe blocks the two beam sensors. The actual length of the pipe can then be calculated through signal conversion, enabling precise cutting.

[0048] See also Figure 9 and Figure 10In some embodiments, the second chuck protection structure and the third chuck protection structure 46 each include a first protective cover 461 disposed around the exterior of the second Y-axis side plate, the second Y-axis side plate drive mechanism / the third Y-axis side plate 83, and the third Y-axis side plate drive mechanism 84; a second protective cover 463 disposed around the exterior of the second chuck drive mechanism / the third chuck drive mechanism; and a fixed cover 462 having two ends connected to the sidewalls of the first protective cover 461 and the second protective cover 463, respectively. The fixed cover 462 is configured to be fixedly connected to the outer wall of the second chuck structure 42 / the third chuck structure 43. In actual use, the first protective cover 461 encloses the second Y-axis side plate and the drive mechanism thereon, the third Y-axis side plate 83 and the drive mechanism thereon, and the second protective cover 4633 encloses the drive mechanism of the second chuck / the third chuck, effectively preventing operators from coming into contact with the drive mechanisms, reducing the probability of safety accidents, and ensuring the personal safety of operators. Furthermore, foreign matter can be prevented from entering the drive mechanism and interfering with its operation, and the appearance of the laser tube cutting machine can be made neater and more aesthetically pleasing. The fixed cover 462 is provided to connect the first protective cover 461 and the second protective cover 463, so that the chuck protection structure forms a whole, which facilitates the installation and removal of the entire chuck protection structure from the laser tube cutting machine.

[0049] Specifically, the second Y-axis side hanging plate driving mechanism and the third Y-axis side hanging plate driving mechanism 84 can be driven by a motor, a gear and a rack, and the driving mechanism is an existing technology.

[0050] For more details, please refer to Figure 4 The second chuck structure 42 is provided with a set of four large rollers 431 arranged in the vertical and horizontal directions, and a set of four small rollers 432 arranged in the vertical and horizontal directions. Figure 9 The third chuck structure 43 is provided with a group of four large rollers 431 arranged in the up, down, left and right directions, a group of two small rollers 432 arranged in the left and right directions, and a group of two clamping claws 433 arranged in the up and down directions. The chuck structure that cooperates with the clamping claws 433 and the rollers enables the third chuck structure 43 to be moved to the left side of the laser cutting assembly 2, that is, the three chuck structures clamp the pipe at the same time. Moreover, the multiple groups of roller groups are provided so that the positions of the second chuck structure 42 and the third chuck structure 43 can remain unchanged, and the first chuck structure 41 can be used to push the pipe, and the sliding force provided by the roller group is used to provide avoidance for the advancement of the pipe. The cooperation of multiple groups of large rollers 431 and small rollers 432, as well as the clamping claws 433, enables the clamping method of the chuck structure to have a wide variety of combinations, which can adapt to pipe cutting in more application scenarios.

[0051] In some embodiments, a chuck protection plate is provided in the inner cavity of the middle portion of the second chuck structure 42 and the third chuck structure 43. The chuck protection plate is provided to protect the inner cavity of the chuck structure.

[0052] See also Figure 9 In some embodiments, the first protective cover 461 includes a first cover body 4611 and a first access panel 4612 detachably connected to the first cover body 4611 via bolts, screws, or other similar screws. The first cover body 4611 defines a first access opening that matches the shape of the first access panel 4612, and the first access panel 4612 covers the first access opening. The first protective cover 461 is made of sheet metal, and the first access opening facilitates access to the drive mechanism within the first protective cover 461 through the first access opening after the first access panel 4612 is removed.

[0053] See also Figure 9 In some embodiments, the second protective cover 463 includes a second cover body 4631 and a second access panel 4633 removably connected to the second cover body 4631 via bolts, screws, or other similar screws. The second cover body 4631 defines a second access opening that matches the shape of the second access panel 4633, and the second access panel 4633 covers the second access opening. Similarly, the second protective cover 463 is made of sheet metal. The second access opening in the second protective cover 463 facilitates access to the drive mechanism within the second protective cover 463 through the second access opening after removing the second access panel 4633.

[0054] See also Figure 9 In some embodiments, the sidewalls and bottom of the second cover 4631 are provided with heat dissipation holes 4632. During device operation, the chuck drive mechanism generates heat. If this heat cannot be dissipated promptly, the internal temperature of the mechanism will rise. The heat dissipation holes 4632 on the sidewalls and bottom form an effective heat dissipation channel, allowing heat to be dissipated to the external environment in a timely manner, allowing the chuck drive mechanism to operate continuously and stably within a suitable temperature range. In this embodiment, the bottom of the first cover 4611 is open, so no additional heat dissipation holes are required.

[0055] See also Figure 9In some embodiments, the fixed cover 462 includes a first extension section 4621 fixed to the sidewall of the first protective cover 461, a second extension section 4623 fixed to the sidewall of the second protective cover 463, and an arcuate section 4622 connecting the first extension section 4621 and the second extension section 4623. The arcuate section 4622 has a curvature consistent with that of the second chuck structure 42 / third chuck structure 43. The lower surface of the arcuate section 4622 abuts against the outer peripheral wall of the upper portion of the second chuck structure 42 / third chuck structure 43, and the arcuate section 4622 is fixed to the second chuck structure 42 / third chuck structure 43. The fixed cover 462 is adapted to the shape of the second chuck structure 42 / third chuck structure 43. In practical applications, the first extension section 4621 and the second extension section 4623 can be designed with different lengths or arcuate sections 4622 with different curvatures to adapt the chuck protective structure to chuck structures with different curvature specifications. In addition, each part of the three-section fixed cover 462 is connected to other parts of the equipment, thereby ensuring that the chuck protection structure is firmly installed and easy to assemble, and the three parts of the fixed cover 462 can be distributed and fixed to the equipment.

[0056] See also Figure 7 and Figure 9 In some embodiments, the outside of the first chuck protection structure 44, the second chuck protection structure and the third chuck protection structure 46 are all provided with a Y-axis drag chain fixing seat 464 that is connected to the first chuck protection structure 44 / the second chuck protection structure / the third chuck protection structure 46, and the Y-axis drag chain fixing seat 464 is used to be fixedly connected to the end of the Y-axis drag chain. The Y-axis drag chain is used to accommodate and protect various cables, air pipes and other pipelines so that they can follow the movement in an orderly manner during the movement of the equipment. The setting of the Y-axis drag chain fixing seat 464 provides a special fixed position for the Y-axis drag chain, ensuring that the Y-axis drag chain can be accurately located on the predetermined path when the equipment is running, avoiding the Y-axis drag chain from swinging randomly or interfering with other components, and making the wiring inside the equipment more standardized and neat. In addition, the Y-axis drag chain fixing seat 464 provides a clear position and connection method for the installation of the Y-axis drag chain. The operator only needs to fix the end of the Y-axis drag chain on the Y-axis drag chain fixing seat 464 to complete the installation. The operation is simple and convenient; it is also conducive to regular maintenance and replacement.

[0057] See also Figure 5In some embodiments, the centering follower mechanism protection structure 5 includes a first protective plate 51 for being fixed to the corresponding mounting side seat 13, and a second protective plate 53 for being fixed to the front side wall of the side-hanging bed 1; a lap plate 52 is provided on the side wall of the first protective plate 51 facing the second protective plate 53, and the lap plate 52 and the inner side wall of the second protective plate 53 are abutted and fixed by bolts; the first protective plate 51, the second protective plate 53 and the mounting side seat 13 and the side-hanging bed 1 form a space for installing the centering follower mechanism 3.

[0058] In actual use, the centering follower mechanism 3 is located on the front side of the side-mounted bed 1, that is, the front side is the operating side. By enclosing the centering follower mechanism 3 in the space surrounded by the first protective plate 51, the second protective plate 53, the mounting side seat 13, and the side-mounted bed 1, the operator can be effectively prevented from accidentally contacting the centering follower mechanism 3. This can avoid the risk of injury to the operator due to accidentally touching the centering follower mechanism 3 while it is running or stationary, such as mechanical injuries such as pinching and abrasion, thereby ensuring the personal safety of the operator. In addition, when installing the first protective plate 51 and the second protective plate 53, or when the centering follower mechanism 3 needs to be maintained or repaired, the connection method of the lap plate 52 and bolts allows for relatively convenient disassembly and installation of the protective structure, which increases the speed of disassembly and assembly and reduces the difficulty and time cost of maintenance work.

[0059] Furthermore, the structure is open at the top and bottom, which makes it easy to observe the operation of the centering follower mechanism 3 from the outside and is beneficial to heat dissipation.

[0060] See also Figure 1 and Figure 2 , Figure 11 and Figure 12In some embodiments, the side-hanging bed 1 is provided with a plurality of first wiring openings 11, a second wiring opening 12 and a third wiring opening 1811 arranged along its length direction; the plurality of first wiring openings 11 correspond to the centering follower mechanism 3, and are used to collect the lines of the corresponding centering follower mechanism 3 to the rear side of the side-hanging bed 1; the plurality of second wiring openings 12 correspond to the unloading mechanism, and are used to collect the lines of the corresponding unloading mechanism to the rear side of the side-hanging bed 1; the number of the third wiring openings 1811 is set to three, and the lines of the first chuck structure 41, the second chuck structure 42 and the third chuck structure 43 are collected to the rear side of the side-hanging bed 1 through the Y-axis drag chain respectively. In actual application, after the centering follower mechanism 3 is uniformly installed on the right side wall of the corresponding installation side seat 13, the cables of the centering follower mechanism 3 can be guided to the rear of the side-hanging bed 1 through the nearest first wiring opening 11 on the side-hanging bed 1; similarly, after assembling the unloading mechanism, the cables of the unloading mechanism are guided to the rear of the side-hanging bed 1 through the nearest second wiring opening 12; the cables of the first chuck structure 41, the second chuck structure 42, and the third chuck structure 43 are guided to the corresponding third wiring opening 1811 through the corresponding Y-axis drag chain, and then gathered to the rear of the side-hanging bed 1.

[0061] See also Figure 1 In some embodiments, an electrical control cabinet 7 is located behind the protective housing 6. This cabinet is used to centrally manage the wiring leading to the rear of the side-mounted bed 1 and the wiring within the protective housing 6. This cabinet allows all wiring and electrical components within the equipment to be integrated into the cabinet 7 through the rear of the side-mounted bed 1, facilitating maintenance and management while providing a clear overview of the electrical components.

[0062] See also Figure 11 and Figure 12 In some embodiments, the side-mounted bed 1 includes a transverse tube assembly 17 composed of multiple stacked and connected transverse tubes, and a reinforcement frame 18 disposed behind the transverse tube assembly 17. The transverse tube assembly 17 is constructed from multiple stacked transverse tubes, and tubes of varying heights can be selected based on the height of the side-mounted bed 1. This simplified manufacturing process eliminates the need for cutting large-scale sheet materials, thus reducing manufacturing costs. The reinforcement frame 18 serves to enhance the structural rigidity of the side-mounted bed 1 and provide routing space for cables, effectively utilizing the spatial layout of the underframe.

[0063] See also Figure 12In some embodiments, the reinforcement frame 18 includes a reinforcement upper crossbeam 181, a reinforcement lower crossbeam 182 disposed below the reinforcement upper crossbeam 181, and a plurality of connecting vertical beams 183 for connecting the reinforcement upper crossbeam 181 and the reinforcement lower crossbeam 182; the bottom of the connecting vertical beam 183 is provided with a wiring notch 184 near the transverse tube group 17; the reinforcement upper crossbeam 181, the reinforcement lower crossbeam 182, and the connecting vertical beam 183 form a wiring cavity; the first wiring opening 11 and the second wiring opening 12 are disposed on the transverse tube group 17, and the third wiring opening 1811 is disposed on the reinforcement upper crossbeam 181. The reinforcement upper crossbeam 181, the reinforcement lower crossbeam 182, and the connecting vertical beam 183 together form a more stable frame structure, significantly enhancing the rigidity and deformation resistance of the entire side-mounted bed 1. By limiting the location of the first wiring opening 11, the second wiring opening 12, and the third wiring opening 1811, the wiring opening 18 is adapted to the location of the centering follower mechanism 3, the unloading mechanism, and the three chuck structures relative to the side-mounted bed 1. Moreover, the wiring notch 184 is designed to cooperate with the first wiring opening 11, the second wiring opening 12, and the third wiring opening 1811, so that the cables collected in the wiring cavity are uniformly processed through the wiring notch 184. The above-mentioned setting provides a more convenient wiring channel, standardizes the direction of the line, is both beautiful and improves safety, and also simplifies the maintenance and inspection process. In addition, the rear side of the reinforcement frame 18 is also fixed with a sheet metal part. The wiring cavity surrounded by the sheet metal part and the reinforcement frame 18 can prevent the lines collected in the wiring cavity from being exposed, thereby improving the overall aesthetics of the equipment.

[0064] To sum up, the present invention encloses the centering follower mechanism 3, the corresponding chuck drive mechanism, the gantry 16 and the laser cutting assembly 2 inside the corresponding structure by setting up a centering follower mechanism protection structure 5, multiple chuck protection structures, and a protection box 6. When the operator is outside the protection structures and the protection box 6, it can effectively prevent the drive mechanisms from touching the operator, and can effectively prevent the scattering and reflection of the laser during the cutting process, thereby avoiding the laser escaping and causing harm to the operator.
