Description

[0001] The present invention is a divisional application with application number: 2024114913324; invention name: A dual-light source laser processing device; and application date: 2024-10-24. Technical Field

[0002] The present invention relates to the technical field of laser processing devices, and in particular to a dual-light source laser processing device. Background Art

[0003] At present, the laser light sources generally used in laser processing machines are: carbon dioxide laser and fiber laser. The wavelengths of these two lasers are different, and their corresponding application fields are also different. The laser wavelength emitted by the fiber laser is shorter and the focal length is smaller, which is suitable for metal cutting; while the laser wavelength emitted by the carbon dioxide laser is longer and the focal length is longer, which is suitable for non-metal cutting.

[0004] In actual applications, some manual workers perform laser processing on products, including metals and non-metals, such as wood, bamboo, rubber and other materials.

In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0046] The present invention will be described in detail below with reference to the accompanying drawings. Figures 1 to 3 shown.

[0047] Example 1: See Figure 1 , Figure 2 A dual-light source laser processing device, comprising: a machine platform, the machine platform is provided with a first light source 5 and a second light source 3, the first light source 5 and the second light source 3 respectively project a first laser and a second laser outward; the machine platform is also provided with a planar two-dimensional moving mechanism 6, the planar two-dimensional moving mechanism 6 is connected to a laser processing head assembly 7 and drives the laser processing head assembly 7 to move horizontally or / and vertically; the planar two-dimensional moving mechanism 6 is provided with a reflector assembly 9, and the reflector assembly 9 is used to reflect the received laser to the laser processing head assembly 7; The machine is also provided with a first laser optical path and a second laser optical path; The first laser light path is provided with a first reflector 46 for projecting the first laser onto the reflector assembly 9; The second laser light path is provided with a second reflector 41 for projecting the second laser onto the reflector assembly 9; The second reflecting mirror 41 is located on the trajectory of the first laser light path; The machine is provided with a position adjuster 4 for adjusting the position of the second reflector 41 , and a controller for controlling the operation of the first light source 5 and the second light source 3 ; the controller is electrically connected to the position adjuster 4 .

[0048] The technical solution is to arrange the first light source 5 and the second light source 3 on the machine platform; thereby the machine has a dual laser light source, the first light source 5 and the second light source 3 can be one of a carbon dioxide laser and a radio frequency laser respectively, and the first light source 5 and the second light source 3 can be the same or different; in this embodiment, two different light sources are used; the laser emitted by the first light source 5 is projected to the reflector assembly 9 through the first laser light path, and then reflected to the laser processing head assembly 7; the laser emitted by the second light source 3 can also be projected to the reflector assembly 9 through the second laser light path, and the reflector assembly 9 can reflect both the first laser and the second laser to the laser processing head assembly 7; since the reflected light paths formed by the first laser and the second laser through the reflector assembly 9 are the same, the incident light paths of the first laser and the second laser to the reflector assembly 9 are the same; for this reason, during the design, the second reflector 41 is arranged on the trajectory of the first laser light path, and of course the first reflector 46 can also be arranged on the trajectory of the second laser light path.

[0049] When in use, since the second reflector 41 is located on the trajectory of the first laser light path, the first light source 5 and the second light source 3 need to be switched for use, and when the first light source 5 is provided, the position of the second reflector 41 needs to be adjusted to make it leave the first laser light path; the technical solution adjusts the position of the second reflector 41 by setting a position adjuster 4; at the same time, the position adjuster 4 is electrically connected to the controller, the controller controls the use status of the first light source 5 and the second light source 3, and sends a signal to the position adjuster 4 according to the use status, and the position adjuster 4 makes adjustments according to the corresponding signal; such as: when the controller controls the first light source 5 to be in use, the controller sends a high level to the position adjuster 4, the position adjuster 4 works, and moves the second reflector 41 outside the first light path trajectory; when the controller controls the first light source 5 to be in non-use state, the controller sends a low level to the position adjuster 4, the position adjuster 4 works, and moves the second reflector 41 to the first light path trajectory. Of course, other adjustment strategies can also be adopted, such as: when the controller controls the second light source 3 to be in use, the controller sends a high level to the position adjuster 4, the position adjuster 4 works, and the second reflector 41 is moved to the first light path track; when the controller controls the second light source 3 to be in non-use state, the controller sends a low level to the position adjuster 4, the position adjuster 4 works, and the second reflector 41 is moved outside the first light path track. The controller can be a prior art, such as a control IC, a processor, etc. Secondly, it should be noted that: due to the different positions of the laser light sources in the first laser light path and the second laser light path, a plurality of intermediate reflectors can be set between the first light source 3 and the first reflector 46; similarly, a plurality of intermediate reflectors can also be set between the second light source 5 and the second reflector 41, so as to project the laser of the first light source onto the first reflector 46 and the laser of the second light source onto the second reflector 41. As in this embodiment, an intermediate reflector is set between the second light source 3 and the second reflector 41, and the intermediate reflector reflects the laser emitted by the second light source onto the second reflector 41. The technology of setting the intermediate reflector is a prior art and will not be repeated.

[0050] See also Figure 4 The position adjuster 4 includes a displacement mechanism connected to the second reflecting mirror 41 .

[0051] By setting a displacement mechanism, the second reflector 41 can be driven to move; the direction of the position movement can be any direction other than the transmission direction of the laser. In this embodiment, the displacement mechanism is exemplarily a vertical linear module, which drives the second reflector 41 to move up and down.

[0052] See also Figure 4 The position adjuster 4 also includes a vertical guiding mechanism, and the second reflecting mirror 41 is connected to the vertical guiding mechanism.

[0053] A vertical guiding mechanism is provided so that the second reflector 41 moves linearly when moving up and down without shaking, which can protect the reflector and also accurately transport the reflector to a predetermined position.

[0054] In this embodiment, the vertical guiding mechanism includes a vertically arranged supporting plate 44, one side of the supporting plate 44 is connected to a vertical guide rail 47, the vertical guide rail 47 is slidably connected to a vertical slide 48, the second reflector 41 is connected to a fixing plate 45, and the fixing plate 45 is fixedly connected to the vertical slide 48.

[0055] Secondly, the displacement mechanism includes a lead screw stepper motor 43 fixedly connected to the support plate 44, the lead screw of the lead screw stepper motor 43 is threadedly connected to the fixed plate 45, and drives the fixed plate 45 to move up and down, and the vertical slide 48 is fixedly connected to the fixed plate 45; when working, the lead screw stepper motor 43 drives its own lead screw to rotate, and the lead screw drives the fixed plate 45 to move up and down, and the fixed plate 45 drives the vertical slide 48 and the second reflector 41 to move up and down along the vertical guide rail 47. In the specific setting, the fixed plate 45 includes a vertical section connected to the vertical slide 48 and a horizontal section connected to the lead screw. In order to facilitate the connection between the lead screw and the horizontal section, the lead screw is threadedly connected with a nut block 42, and the nut block 42 is connected to the horizontal section. The nut block 42 is connected to the horizontal section, which can effectively increase the connection area.

[0056] Secondly, the upper and lower ends of the support plate 44 are respectively connected with sensors, and the fixing plate 45 is connected with a sensing block that matches the sensor. The sensor and the sensing block are provided to assist in controlling the position of the fixing plate 45 and the second reflector 41 to rise and fall.

[0057] See also Figure 4 , the first reflector 46 is connected to the support plate 44. To facilitate fixing the first reflector 46, in the present technical solution, the first reflector 46 is connected to the support plate 44 via a connecting frame. When switching the light source, the lead screw stepper motor 43 drives the vertical slider to drive the second reflector 41 to move up and down to avoid the first laser light path.

[0058] See also Figure 3 The first optical path and / or the second optical path is provided with a light gate 8 for controlling the passage of the laser, and the light gate 8 is connected to a driving unit for driving the light gate 8 to move or rotate; when the first light source 5 or the second light source 3 is in a stopped working state, the driving unit drives the light gate 8 to operate, and the light gate 8 blocks the corresponding first laser or second laser.

[0059] See also Figure 1 , Figure 2The machine is connected to a casing 1, the planar two-dimensional moving mechanism is located in the casing 1, a window is provided at the front upper end of the casing 1 and is connected to a protective cover 2, the rear end of the protective cover 2 is hinged to the casing 1, and a supporting unit for supporting the protective cover 2 to be opened is connected between the protective cover 2 and the casing 1; the casing 1 or the protective cover is connected to a sensor for sensing that the protective cover is opened, the sensor is electrically connected to the control unit, and when the protective cover is opened, the control unit drives the shutter 8 to operate to block the corresponding first laser or second laser.

[0060] When the laser processing assembly is working, the laser is harmful to the human body. In order to avoid laser exposure and damage to the human body, a housing 1 is set to shield the planar two-dimensional mechanism; at the same time, a protective cover 2 is set to facilitate the operation of the workpiece on the workbench; when the protective cover 2 is opened, in order to protect the operator, it is necessary to shut down the laser transmitter or block the laser. If the laser is shut down, it will take some time to restart the laser. Therefore, this technical solution adopts a shielding method, by setting a sensor to sense the state of the protective cover 2. Once the protective cover 2 is opened, it acts as a shutter 8 to shield the first laser or the second laser. Secondly, the support unit can use gas springs, support rods, etc.; it can be existing technology.

[0061] In this embodiment, the driving unit includes a driving motor, and the control unit is connected to the driving motor. When a signal is received from the sensor, the driving motor is controlled to drive the shutter 8 to rotate. The driving unit can also be a cylinder, which drives the shutter 8 to move to control whether the laser passes.

[0062] See also Figure 5 The planar two-dimensional moving mechanism includes longitudinal moving mechanisms 61 located on both sides and a transverse moving mechanism located in the middle, and the reflector assembly 9 is arranged on the transverse moving mechanism; the transverse moving mechanism includes a transverse guide rail 62 located in the middle, a vertical substrate 71 slidably connected to the transverse guide rail 62, and a transverse driving device for driving the vertical substrate 71 to move, and the two ends of the transverse guide rail 62 are respectively connected to the corresponding longitudinal moving mechanism 61.

[0063] In the present technical solution, the length direction of one of the longitudinal guide rails is parallel to the direction in which the first laser is reflected from the first reflector 46. The reflector assembly 9 is arranged on the transverse moving mechanism. When adjusting the position, the reflector assembly 9 moves longitudinally along with the transverse moving mechanism, so that the reflector assembly 9 can always receive the first laser or the second laser. In order to facilitate the setting of the transverse moving mechanism and the laser processing head assembly 7, the transverse moving mechanism is provided with a transverse guide rail 62. The laser processing head is slidably connected to the transverse guide rail 62 and moves laterally under the drive of the transverse driving device.

[0064] See also Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Fig. 9 , Fig.10 The two sides of the transverse guide rail 62 are respectively connected to a main fixed plate 64 and a secondary fixed plate 68, and the transverse drive device includes a first pulley 67 fixed to the main fixed plate 64 and a second pulley 69 fixed to the secondary fixed plate 68. The first pulley 67 is connected to a pulley drive motor 66, and the first pulley 67 is connected to the second pulley 69 through a transverse belt. Figure 6 , Fig.11 The upper end of the back side of the vertical substrate 71 is connected to a plurality of upper pulleys 72, and the lower end of the back side of the vertical substrate 71 is connected to a plurality of lower pulleys 710. The upper end surface and the lower end surface of the transverse guide rail 62 are respectively provided with guiding structures arranged opposite to the upper pulleys 72 and the lower pulleys 710, and the left side surface and the right side surface of the vertical substrate 71 are respectively provided with belt connection structures 73.

[0065] In this embodiment, when the main fixing plate 64 and the auxiliary fixing plate 68 are set, the main fixing plate 64 is located on the side of the transverse guide rail 62 away from the reflector assembly 9. Secondly, the pulley drive motor 66 is fixed to the main fixing plate 64 and is drivingly connected to the first pulley 67. The pulley drive motor 66 drives the first pulley 67 to connect. In order to facilitate the fixing of the pulley drive motor 66 and the first pulley 67, a transmission mechanism such as a gear transmission mechanism can be set on the main fixing plate 64. In this embodiment, a belt transmission mechanism 65 is set on the main fixing plate 64, and the pulley drive motor 66 is connected to the first pulley 67 through the belt transmission mechanism 65. Specifically, the belt transmission mechanism 65 includes a main pulley connected to the rotating shaft of the pulley drive motor 66 and an auxiliary pulley coaxially connected to the second pulley 69. The pulley drive motor 66 drives the first pulley 67 to rotate, and the first pulley 67 drives the second pulley 69 to rotate through the belt. At the same time, the belt moves between the first pulley 67 and the second pulley 69. When the belt moves, it drives the vertical base plate 71 to move laterally along the transverse guide rail 62. In order to reduce the friction between the transverse guide rail 62, in this embodiment, the back of the vertical base plate 71 is provided with an upper pulley 72 and a lower pulley 710, and the upper end face and the lower end face of the transverse guide rail 62 are respectively provided with a guide structure. The upper pulley 72 and the lower pulley 710 are respectively against the guide structures of the upper and lower end faces of the transverse guide rail 62, and roll relative to each other, and make a linear transverse movement under the guidance of the guide structure. The upper pulley 72 and the lower pulley 710 are in rolling contact with the transverse guide rail 62, which effectively reduces the friction coefficient.

[0066] See also Figure 5 , Figure 6 The guide structure includes a transverse guide rod 63 arranged on the upper end surface and the lower end surface of the transverse guide rail 62, and the middle part of the side of the upper pulley 72 and the lower pulley 710 are provided with an annular groove matching the transverse guide rail 62; see Fig. 9The upper pulley 72 and / or the lower pulley 710 are adjustable pulleys, a connecting shaft is provided in the middle of the adjustable pulley, a through hole is provided on the back of the base plate for the connecting shaft to pass through, the aperture of the through hole is larger than the diameter of the connecting shaft, a countersunk hole 74 is provided on the front of the base plate, an eccentric wheel 77 is provided in the countersunk hole 74, an eccentric hole 75 matching the connecting shaft is provided in the middle of the eccentric wheel 77, and the connecting shaft passes through and is inserted into the eccentric hole 75; a plurality of adjustment holes 78 are provided on the end face of the eccentric wheel 77, wherein a plurality of adjustment holes 78 are provided with internal threads, and the adjustment holes 78 are connected with fastening bolts 76.

[0067] The technical solution provides a transverse guide rod 63, and an annular groove is provided in the middle of the side of the upper pulley 72 and the lower pulley 710, so that the upper end of the transverse guide rod 63 is inserted into the annular groove of the upper pulley 72 and the lower pulley 710. When working, the upper pulley 72 and the lower pulley 710 roll along the corresponding transverse guide rod 63 respectively, and the rolling direction of the upper pulley 72 and the lower pulley 710 can be guided; secondly, the provision of the transverse guide rod 63 can reduce costs, and the upper pulley 72 and the lower pulley 710 can be When the transverse guide rod 63 rolls, the upper pulley 72, the lower pulley 710 and the transverse guide rod 63 are all worn. In order to reduce wear and extend the service life, it is understandable that the materials of the upper pulley 72, the lower pulley 710 and the transverse guide rod 63 are all selected to be hard and wear-resistant; if the transverse guide rod 63 is not provided separately, the transverse guide rail 62 needs to be selected to have a wear-resistant material. By providing the transverse guide rod 63 additionally, it is only necessary to rotate the material of the transverse guide rod 63 to improve wear resistance. At the same time, it is also convenient for replacement. When the transverse guide rod 63 is severely worn, it is only necessary to replace the transverse guide rod 63.

[0068] Secondly, during installation, since the transverse guide rail 62 and the laser processing head assembly 7 are two different components, when the laser processing head assembly 7 is reassembled and assembled to the transverse guide rail 62, since the upper pulley 72 and the lower pulley 710 are all snap-fitted to the corresponding transverse guide rod 63, if the upper pulley 72 and the lower pulley 710 are fixedly connected to the vertical base plate 71, the positions of the upper pulley 72 and the lower pulley 710 cannot be adjusted, and the snap-fitting of the upper pulley 72 and the lower pulley 710 to the transverse guide rail 62 cannot be achieved; the technical solution is achieved by setting at least one of the upper pulley 72 and the lower pulley 710 as an adjustable pulley; in this embodiment, the lower pulley 710 is set as an adjustable pulley, and the connecting shaft of the lower pulley 710 is connected to the eccentric hole 75 of the eccentric wheel 77, and when assembled with the transverse guide rail 62, it is rotated by a tool The eccentric wheel 77 causes the height of the lower pulley 710 to drop, the gap between the lower pulley 710 and the upper pulley 72 to increase, and the distance between the upper pulley 72 and the lower pulley 710 is greater than the distance between the transverse guide rods 63 located on the upper and lower end surfaces of the transverse guide rails 62; then the vertical base plate 71 is moved so that the upper pulley 72 is opposite to the transverse guide rod 63 located above, and the lower pulley 710 is opposite to the transverse guide rod 63 located below; the vertical base plate 71 is loosened, and the side surface of the upper pulley 72 abuts against the transverse guide rail 62 above; then the workpiece is used to rotate the eccentric wheel 77, so that the lower pulley 710 moves upward and abuts against the transverse guide rail 62 located below; finally, the eccentric wheel 77 is fixed with the fastening bolts 76, and the fastening bolts 76 rotate relative to the eccentric wheel 77 and abut against the vertical base plate 71.

[0069] Thirdly, after long-term use, when the upper pulley 72 and / or the lower pulley 710 are seriously worn, the clamping of the upper pulley 72 and the lower pulley 710 on the transverse guide rail 62 is loose, and the lower pulley 710 may have been separated from the transverse guide rod 63 located below. The vertical substrate 71 moves under the drive of the belt, and the vertical substrate 71 has a small up and down jump, which affects the normal operation of the laser processing head assembly 7. This technical solution adopts an eccentric wheel 77 structure. By operating the eccentric wheel 77, the eccentric wheel 77 rotates and drives the lower pulley 710 to rotate. At the same time, the lower pulley 710 also moves upward, so that the lower pulley 710 abuts against the transverse guide rod 63 located below; thereby overcoming the influence of the wear of the upper pulley 72 and the lower pulley 710.

[0070] See also Fig. 9The belt connection structure 73 includes a main clamping block 731 and a secondary clamping block 732 for connecting with the belt. A mounting notch 733 for mounting the secondary clamping block 732 is provided in the middle of the back side of the main clamping block 731. The main clamping block 731 is connected to the secondary clamping block 732 through a connecting piece, and the connecting piece can be a bolt or the like; a plurality of through holes 735 are provided on the outer end face of the main clamping block 731, and a connecting hole arranged opposite to the through hole 735 is provided on the side of the vertical base plate 71. The main clamping block 731 is connected with a side bolt 734, one end of the side bolt 734 passes through the through hole 735 and is inserted into the connecting hole of the vertical base plate 71, and an adjusting nut 736 is threadedly connected to the middle part of the side bolt 734, and the adjusting nut 736 abuts against the main clamping block 731.

[0071] The belt can be connected to the belt connecting structures 73 on both sides in two ways: 1. The belt is a closed-loop structure, and a section of the belt is clamped between the belt connecting structures 73 on both sides; and the length of a section of the belt is greater than the spacing between the belt connecting structures 73 on both sides; 2. The belt is an open-loop structure, the middle part of the belt is disconnected, and the two ends of the disconnected belt are respectively connected to the corresponding belt connecting structures 73.

[0072] The belt passes through the main clamp block 731 and the auxiliary clamp block 732, and the main clamp block 731 and the auxiliary clamp block 732 are connected by a connecting piece and clamp the belt. Secondly, the belt connection structure 73 can adjust the tension of the belt; two connection points are formed on the belt, and the connection points are the connection points between the belt and the belt connection structure 73; when working, the working length of the belt is: the belt between the two connection points and around the first pulley 67 and the second pulley 69. For the convenience of description, this section of the belt length is set as the effective working length; when the assembly is completed, the tension of the belt needs to be adjusted, that is, the effective working length of the belt is within a predetermined value or a predetermined range, so that the belt can work normally; currently, when adjusting the belt tension in the industry, a tension adjustment wheel is generally used, and by setting a tension adjustment wheel with adjustable position, when adjusting the belt tension, the position of the tension adjustment wheel is changed, so as to achieve the purpose of adjusting the belt tension; in this embodiment, setting a tension adjustment wheel with adjustable position will make the overall structure complicated and the cost is high. In this embodiment, side bolts 734 are provided on the main clamping block 731 and are threadedly connected to the vertical base plate 71, so that the effective use length of the belt can be adjusted; when in use, the belt continuously maintains an outward pulling force on the main clamping block 731, so that the main clamping block 731 and the head of the side bolt 734 are abutted against each other; when adjusting, by rotating the side bolt 734, the side bolt 734 moves toward or away from the base plate, and the side bolt 734 drives the main clamping block 731 to move left and right. After the main clamping block 731 moves left and right, the connection point between the belt connecting structure 73 and the belt also moves left and right, thereby changing the effective use length of the belt.

[0073] Since the main clamping block 731 and the side bolt 734 are in a socket structure, the main clamping block 731 can move laterally relative to the side bolt 734; during use, the laser processing head assembly 7 will continuously move laterally left and right, and during the movement of the laser processing head, it is inevitable that the main clamping block 731 will be displaced against the side bolt 734 for a short period of time, causing the laser processing head to shake left and right for a short period of time, affecting the processing accuracy of the laser processing head; for this reason, the present embodiment adopts the method of setting an adjusting nut 736, and the main clamping block 731 is clamped by the adjusting nut 736 and the head of the side bolt 734, thereby preventing the main clamping block 731 from moving relative to the side bolt 734.

[0074] Secondly, you can also have another structure like: The belt connection structure 73 includes a main clamp block 731 and a secondary clamp block 732 for connecting with the belt. A mounting notch 733 for mounting the secondary clamp block 732 is provided in the middle of the back side of the main clamp block 731. The main clamp block 731 is connected to the secondary clamp block 732 through a connecting piece. The outer end face of the main clamp block 731 is provided with a plurality of through holes 735. The side surface of the vertical substrate 71 is provided with connecting holes arranged opposite to the through holes 735. The main clamp block 731 is connected with a side threaded column. One end of the side threaded column passes through the through hole 735 and is inserted into the connecting hole of the vertical substrate 71. The side threaded column is connected with two fixing nuts, which are clamped on both sides of the main clamp block 731.

[0075] The main clamping block 731 is clamped and fixed and its position is adjusted by two fixing nuts. When adjusting the position, the two fixing nuts can be rotated at the same time to drive the main clamping block 731 to move left and right. Of course, other adjustment methods can also be used. The main clamping block 731 cannot move left and right relative to the side screw rod by clamping the two fixing nuts. When the side screw rod is connected to the base plate, it can be connected by thread or by plugging and interference fit.

[0077] In this embodiment, the guiding structure adopts another structure, see Fig.12 A guide groove 610 is provided on the upper and lower end surfaces of the transverse guide rail 62. The middle parts of the sides of the upper pulley 72 and the lower pulley 710 are convex outward, and the upper pulley 72 and the lower pulley 710 roll along the guide groove 610. Fig.13 , the back of the vertical substrate 71 is provided with an adjustment structure, so that the clamping force of the upper pulley 72 and the lower pulley 710 on the transverse guide rail 62 can be conveniently installed and adjusted. When the vertical substrate 71 is assembled with the transverse guide rail 62, the upper pulley 72 and the lower pulley 710 are respectively inserted from the front of the transverse guide rail 62 until the upper pulley 72 moves to the upper part of the guide groove 610, and the lower pulley 710 moves to the lower part of the guide groove 610, and then the vertical substrate 71 is released, and the lower end of the upper pulley 72 falls into the upper guide groove 610; and because the elastic member 714 pushes the adjustment bolt 711 to move downward, the adjustment block 715 rotates, and the lower pulley 710 moves upward under the drive of the adjustment block 715, and the upper end of the lower pulley 710 falls into the lower guide groove 610. Thereby, the phenomenon that the lower pulley 710 cannot abut against the bottom surface of the lower guide groove 610 is avoided. The cam 714 is pressed downwardly when the adjusting screw 711 is in a state of rotation and the cam 715 is in a state of rotation, so that the adjusting screw 711 is pressed downwardly when the adjusting screw 711 is in a state of rotation and the cam 715 is in a state of rotation.

The fixing plates 729 are provided with a transverse groove 720 matched with the connecting shaft. The end of the connecting shaft extends into the transverse groove 720. The rear end of the driving wheel 727 extends out of the fixing plate 729 and abuts against the transverse guide rail 62. An intermediate wheel 728 is provided between one of the driving wheels 727 and the adjusting ring 726. The intermediate wheel 728 is rotatably connected with the fixing plate 729. The side of the intermediate wheel 728 abuts against the side of the adjusting ring 726. A boss 725 is provided in the middle of the back of the vertical base plate 71. The boss 725 The upper end of the zeroing rod 730 is connected with a guide cylinder 724 that cooperates with the upper end of the zeroing rod 730, the boss 725 is provided with a through hole, the upper end of the zeroing rod 730 passes through the boss 725 and the guide cylinder 724 in sequence, the upper end side surface of the zeroing rod 730 is provided with a vertical groove, the inner side surface of the guide cylinder 724 is provided with a convex point that cooperates with the vertical groove, and the convex point is inserted into the vertical groove; the upper end of the zeroing rod 730 is connected with a sensing block 721, and the upper end of the back side of the vertical substrate 71 is connected with a sensor 723, and the sensor 723 is provided with a sensing hole that cooperates with the sensing block 721.

[0079] The present technical solution is to set a zeroing rod 730 component to assist the laser processing head in focusing. At present, the laser processing head assembly 7 needs to obtain the height of the laser processing head when focusing. However, the laser processing head assembly 7 is not equipped with a distance measuring unit such as a rangefinder. Therefore, it is necessary to know a relative height of the laser processing head assembly 7 and then make adjustments based on the relative height. When focusing, the laser processing head assembly 7 remains stationary, and the zeroing rod 730 moves downward under the action of gravity. Since the convex point in the guide cylinder 724 cooperates with the vertical groove at the upper end of the side of the zeroing rod 730, the zeroing rod 730 moves linearly downward. At the same time, the side edge 716 of the zeroing rod 730 abuts against the steel ball 719 of the adjustment ring 726 and pushes the steel ball 719 to move along the spiral gap 717. The steel ball 719 carries The adjusting ring 726 rotates until the sensing block 721 abuts against the upper end of the guide cylinder 724; at this time, the sensing block 721 is just below the sensor block, the steel ball 719 is still in the gap 717, and the lower end surface of the zeroing rod 730 is below the laser processing head assembly 7; then the control system of the laser processing device drives the worktable to move upward, and the worktable drives the workpiece thereon to move slowly upward together until the workpiece contacts the zeroing rod 730, and the zeroing rod 730 is pushed by the workpiece, and the zeroing rod 730 drives the sensing block 721 to move upward, and the sensor 723 senses the sensing block 721 and sends a signal to the control system, and the control system controls the worktable to stop rising. At this time, the height of the laser processing head assembly 7 is the reference 0 height, and then the control system controls the worktable to move downward a predetermined distance to complete the focusing.

[0080] After the focusing is completed, the control system will control the planar two-dimensional moving laser to drive the laser processing head assembly 7 to perform two-dimensional movement. Since the lower end surface of the zeroing rod 730 is located below the laser processing head assembly 7 at this time, during the two-dimensional movement, the zeroing rod 730 will have a high probability of colliding with other foreign objects placed on the workbench, thereby damaging both the zeroing rod 730 and the foreign objects. To avoid this situation, it is necessary to retract the zeroing rod 730 during operation, that is, drive the zeroing rod 730 to move upward; in this embodiment, a combination structure of an adjustment ring 726, a driving wheel 727 and an intermediate wheel 728 is used to drive the zeroing rod 730 to move upward.

[0081] Referring to the accompanying drawings, when the laser processing head assembly 7 moves to the left, the two driving wheels 727 abut against the transverse guide rail 62 and are subjected to the friction force of the transverse guide rail 62. The direction of the friction force is rightward and simultaneously pushes the driving wheel 727 to move to the right. The two ends of the connecting shaft of the driving wheel 727 move along the transverse slide groove 720 respectively and move to the right end of the transverse slide groove 720; the driving wheel 727 on the right side is separated from the adjusting ring 726; for ease of understanding, in this embodiment, the intermediate wheel 728 is exemplarily arranged on the left side of the adjusting ring 726; of course, it can also be arranged on the right side of the adjusting ring 726; the driving wheel 727 on the left side abuts against the intermediate wheel 728, Then the driving wheel 727 rotates driven by the friction force, and also drives the intermediate wheel 728 to rotate, and the intermediate wheel 728 drives the adjusting ring 726 to rotate. When the adjusting ring 726 rotates, the steel ball 719 moves along the gap 717 and drives the zeroing rod 730 to move upward. For ease of understanding, when the laser processing head assembly 7 moves to the left, the driving wheel 727 rotates in a clockwise direction driven by the friction force, and the driving wheel 727 rotates in the opposite direction to the intermediate wheel 728. Therefore, the intermediate wheel 728 rotates in a counterclockwise direction, and the intermediate wheel 728 rotates in the opposite direction to the adjusting ring 726. The adjusting ring 726 rotates in a clockwise direction. When the adjusting ring 726 rotates clockwise, the zeroing rod 730 is driven to move upward.

[0082] When the laser processing head assembly 7 moves to the right, since the two driving wheels 727 abut against the transverse guide rail 62 and are subjected to the friction force of the transverse guide rail 62, the direction of the friction force is leftward and simultaneously pushes the driving wheel 727 to move leftward, the two ends of the connecting shaft of the driving wheel 727 move along the transverse slide groove 720 respectively and move to the left end of the transverse slide groove 720; the driving wheel 727 on the left side is separated from the middle wheel 728; the driving wheel 727 on the right side abuts against the adjusting ring 726, and the driving wheel 727 rotates counterclockwise, and at the same time, the driving wheel 727 and the adjusting ring 726 have opposite rotation directions, and the adjusting ring 726 rotates clockwise. When the adjusting ring 726 rotates clockwise, the driving zeroing rod 730 moves upward.

[0083] When the zeroing rod 730 moves upward until the ball is out of the gap 717, the ball will move around the lower end surface of the open ring sheet 718. Since the opening of the open ring sheet 718 is arranged opposite to the lower end opening of the double helix side edge 716, when the ball passes through the opening of the ring sheet 718, the ball will enter the lower end opening of the double helix side edge 716 for a short time and then move out from the opening; it can be understood that, in order to facilitate the removal of the ball, the two ends of the opening of the ring sheet 718 are connected to the two ends of the lower end opening of the double helix side edge 716 to form an arc transition. When the ball abuts against the lower end surface of the ring sheet 718, the lower end surface of the zeroing rod 730 can be located above the lower end surface of the vertical substrate 71, and the zeroing rod 730 is in a hidden state. When the laser processing head assembly 7 stops working, the zeroing rod 730 moves downward under its own gravity, and the annular piece 718 presses against the ball, causing the adjusting ring 726 to rotate. The ball moves along the lower end surface of the annular piece to the highest point of the annular piece 718, i.e., the opening, and then the ball enters the lower end opening of the double helix side edge 716 and enters the gap 717; the ball moves along the gap 717 again, and the adjusting ring 726 rotates until the zeroing rod 730 descends to the sensing block 721 and abuts against the guide cylinder 724.

[0084] Preferably, a spring 722 is disposed on the outer sleeve of the guide cylinder 724 , and two ends of the spring 722 are fixedly connected to the sensing block 721 and the boss 725 , respectively.

[0085] By providing the spring 722 , the force of the zero return rod 730 moving downward can be increased, thereby accelerating the downward movement of the zero return rod 730 .

[0086] Secondly, in order to facilitate the free rotation of the driving wheel 727 and the intermediate wheel 728, a bearing can be arranged between the wheel body of the driving wheel 727 and the connecting shaft. The wheel body of the driving wheel 727 can rotate freely relative to the connecting shaft, and the intermediate wheel 728 can adopt the same structure as the driving wheel 727.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
