Description

TECHNICAL FIELD

[0002] Laser processing is to make the material change physically or chemically by scanning the target surface with a laser beam with appropriate energy density converging on the working surface, so as to achieve the purpose of processing. Usually, in the processing process, different wave bands of lasers need to be selected to process the surface of the workpiece due to different workpiece materials, and field lenses with different light transmission wave bands need to be matched. In addition, field lenses with different focal lengths need to be selected due to different processing ranges. Therefore, in order to meet the diversity of workpiece materials and processing ranges of laser processing, a laser processing device is often equipped with multiple field lenses and is adapted to different processing distances. Due to the erosion effect of laser on the surface of the workpiece, pungent waste gas and tiny particles are generated and diffused into the air to pollute the surrounding environment, and the high energy density characteristics of laser make it have the risk of causing damage to the human eye. Most of the existing laser processing devices are still open type, and only protective goggles are provided for the operator, which is not convenient to use, and the pollution in the processing process cannot be controlled.

[0023] Example 1 See attached document Figures 1-8 As shown, this invention provides a technical solution: a dual-source laser processing device, including a worktable 1, a headstock 3, and a laser optical assembly 10. The headstock 3 is positioned above the worktable 1, and the worktable 1 is located directly below the headstock 3, with an area larger than the downward projection area of ​​the headstock 3. The upper surface of the worktable 1 is connected to the headstock column 5, and its surface has multiple rows of threaded holes with standard hole spacing for easy fixing of laser processing accessories. The headstock 3 is connected to the headstock column 5 and is used to process workpieces in the processing area. The lower end of the headstock column 5 is connected to the worktable 1, and the upper end is connected to the headstock 3, forming the support structure of the entire processing device. The laser optical assembly 10 is used to enable different light sources to be used with different field lenses to laser process workpieces of different materials. The laser optical assembly 10 is disposed inside the machine head base 3. The laser optical assembly 10 includes a galvanometer assembly 101, an optical path support structure 102, a blue light source 103, a reflective optical module 104, and a field lens assembly 105. The field lens assembly 105 includes laser field lenses with different focal lengths, which can converge red and blue laser light onto the processing surface to perform laser processing on the workpiece. The machine head base 3 is characterized by having a protective cover 2 on its outer side to filter the laser beam reflected during laser processing. A moving component is provided between the machine head base 3 and the protective cover 2, allowing the protective cover 2 to move up and down on the outer side of the machine head base 3 via the moving component. A protective cover limiting component 7 is provided between the protective cover 2 and the machine head base 3's base column 5 to limit the movement position of the protective cover 2.

[0024] The embodiments of the present invention are also implemented through the following technical solutions.

[0025] In an embodiment of the present invention, the protective cover 2 has a U-shaped design on its top surface, so that the protective cover 2 is framed on the outside of the base head. The moving component includes a protective cover guide rail 4 and rollers 6. The protective cover guide rail 4 is screwed to both sides of the machine base column 5. The inner side of the protective cover 2 is screwed to a slider that is slidably connected to the protective cover guide rail 4. By the cooperation of the slider and the protective cover guide rail 4, the protective cover 2 can be manually controlled to slide up and down on the outside of the machine head base 3. The rollers 6 are set on both sides of the machine head base 3. The rollers 6 are in rolling connection with the inner wall of the protective cover 2. When the protective cover 2 moves to the installation position of the rollers 6, the inner wall contacts the surface of the rollers 6, realizing the auxiliary orientation of the protective cover 2 to move up and down.

[0026] In an embodiment of the present invention, a fastening screw 12 is provided at the bottom of the protective cover 2. The fastening screw 12 is threadedly engaged with the protective cover 2, and the fastening screw 12 does not extend into the interior of the protective cover 2, but is only connected to the protective cover 2. The protective cover 2 is connected to the upper protective cover limiting member 7 through the fastening screw 12. A locking member 8 is provided on the surface of the workbench 1. The position of the locking member 8 corresponds to the fastening screw 12. The locking member 8 has a "Y" shaped design, and its upper end is made of elastic metal material for clamping the fastening screw 12.

[0027] Specifically, the locking element 8 is installed on both sides of the workbench 1. When the protective cover 2 reaches the surface of the workbench 1, it provides clamping force to prevent the protective cover 2 from springing back upward. The locking element 8 has a "Y"-shaped design with an opening at the top and two branches connected at the base. When the protective cover 2 descends to the surface of the workbench 1, the fastening screw 12 installed on the bottom side of the protective cover 2 will be inserted into the bottom of the locking element 8 along the opening at the top. Because the two branches of the locking element 8 are made of elastic metal and have a certain degree of elasticity, when the fastening screw 12 on the bottom side of the protective cover 2 enters the locking element 8, the two branches will be pushed apart to the sides. When the fastening screw 12 on the back of the protective cover 2 reaches the inner bottom of the locking element 8, the two branches will spring back, the opening will be restored, and the locking element 8 will clamp the fastening screw 12, thereby preventing the protective cover 2 from springing back upward.

[0028] In an embodiment of the present invention, the protective cover limiting member 7 is disposed on both sides of the upper end near the base column 5. The protective cover limiting member 7 includes a housing 701, a fixing post 702, an elastic rope 703, a lever 704, a limiting plate 706, and a torsion spring 707. The housing 701 is screwed to both sides of the upper end of the base column 5. The fixing post 702 is disposed at the inner center of the housing 701. The elastic rope 703 is wrapped around the outer side of the fixing post 702. The lever 704 is disposed on the bottom side of the housing 701. The limiting plate 706 is fixed to the inner side of the lever 704 and is located inside the housing 701. Its front end is located on one side of the elastic rope 703. The torsion spring 707 is disposed between the elastic rope 703 and the fixing post 702.

[0029] In an embodiment of the present invention, one end of the fixing post 702 is fixedly connected to the outer casing 701, and the other end is screwed to the outer casing 701. This facilitates the removal of the outer casing 701 to replace the elastic cord 703 and prevents the fixing post 702 from breaking when the elastic cord 703 has excessive retraction force. The fixing post 702 secures one end of the elastic cord 703, allowing the fixing post 702 to be locked with screws or bolts after the elastic cord 703 has extended. The two ends of the torsion spring 707 are respectively... The elastic cord 703 is screwed to the fixing post 702. The torsion spring 707 provides a certain rebound force for the winding of the elastic cord 703. The bottom side of the outer shell 701 has a groove for the other end of the elastic cord 703 to extend out, so as to provide space for the elastic cord 703 to stretch. The other end of the elastic cord 703 is wrapped around the rod of the fastening screw 12. The protective cover limiting member 7 is connected to the protective cover 2 through the elastic cord 703, and the elastic cord 703 is installed on the fastening screw 12 by fixing components such as clamps.

[0030] It should be noted that the elastic cord 703 is prone to elasticity failure if it is kept in a taut state for a long time. Therefore, the duration of its limiting effect on the protective cover 2 should be determined according to the usage time of the elastic cord 703 of different materials to avoid the limiting effect of the protective cover 2. The elastic cord 703 should be replaced in time. In addition, the elasticity of the torsion spring 707 needs to be selected according to the actual situation to avoid the elastic cord 703 retracting too quickly, causing collision and wear between the elastic cord 703 and the outer shell 701 or other parts. If the elasticity is too small, it will not be able to effectively drive the elastic cord 703 to retract.

[0031] In an embodiment of the present invention, a rack is fixed to the bottom side of the outer shell 701. The rack is located below the limiting plate 706 and passes through the lever 704. The lever 704 is movably connected to the rack, so that the lever 704 moves on the rack and drives the limiting plate 706 inside it to move. A plunger for limiting is provided between the tooth groove 705 surface of the rack and the lever 704. The plunger is located inside the front side near the lever 704. The plunger includes a plunger shell 708, a spring 709 and a plunger ball. The plunger shell 708 is threaded to the lever 704. The plunger shell 708 is hollow and has a "U" shaped cross section. The spring 709 is located between the plunger shell 708 and the plunger ball. The plunger ball is located at the end of the plunger shell 708 and is movably connected to the plunger shell 708. The diameter of the plunger ball is smaller than the width of the tooth groove 705 of the rack and is movably connected to the rack.

[0032] Specifically, the plunger housing 708 is fixed inside the lever 704 by threads. When the lever 704 moves, the plunger moves along with it. At the same time, the plunger ball is normally stuck in the tooth groove 705 of the rack. When the lever 704 is moved manually, the plunger ball is squeezed by the teeth on the rack and moves and contracts into the plunger housing 708. At the same time, the spring 709 is compressed. When it moves to the next tooth groove 705, the plunger ball pops out based on the force of the spring 709 and gets stuck in the tooth groove 705. It continues to move until the limiting plate 706 controlled by the lever 704 abuts against the elastic rope 703 and limits the elastic rope 703. Conversely, when it is necessary to release, the lever 704 is manually controlled to move in the opposite direction, and the plunger is retracted and released in the same way.

[0033] It should be noted that the elastic force of spring 709 needs to be selected according to the weight of protective cover 2 borne by elastic rope 703, so as to avoid insufficient elastic force of spring 709, and the situation where the weight of protective cover 2 pulls elastic rope 703, causing limit plate 706 to move and plunger component to fail.

[0034] In use, the protective cover limiting component 7 is connected to the protective cover 2 via the elastic rope 703. In the initial state, part of the protective cover 2 covers the outside of the machine head seat 3, and part is in the processing area. When the protective cover 2 needs to be used, it is manually pulled down. At this time, the elastic rope 703 is pulled out from the outer shell 701 until the protective cover 2 reaches the position that needs protection. One hand holds the protective cover 2, and the other hand moves the lever 704 on the outer shell 701. The limiting plate 706 on the lever 704 presses against the elastic rope 703. The lever 704 limits the position through the plunger component and fixes the position of the limiting plate 706, thereby limiting the pull-out length of the elastic rope 703 and pulling the protective cover 2 to achieve the limiting work of the protective cover 2.

[0035] In an embodiment of the present invention, the galvanometer assembly 101 includes a galvanometer driver 1011, a field lens identification contact 1012, and an optical galvanometer 1013, used to identify field lens information and realize the scanning of the laser processing beam within the processing area. A main control board 9 is also provided inside the headstock 3. The input terminal of the main control board 9 is communicatively connected to the output terminal of the field lens identification contact 1012. The main control board 9 is a PCB board used to control the working logic of each component of the laser processing equipment. The field lens in the field lens assembly 105 is screwed into place with the galvanometer assembly 101 via a threaded interface. If it is a randomly matched field lens, the protruding part of different models of random field lenses will contact the field lens identification contact. The other contacts in 1012 generate different electrical signals, which are transmitted to the main control board 9. The main control board 9 determines the field lens model based on the different electrical signals according to a pre-set program, and sets the working parameters of the processing equipment. If it is a field lens of another brand, it will not contact the field lens identification contact 1012, and no electrical signal will be generated. The processing equipment working parameters are pre-set in the main control board 9 according to the field lens model to achieve the working state. That is, the model of the corresponding field lens is determined by the electrical signal of the field lens identification contact 1012 contacting the field lens, and the corresponding processing equipment parameters are given, realizing the function of automatically identifying field lens information.

[0036] It is worth noting that the control method in this application is controlled by the main control board 9. The control circuit of the main control board 9 can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. This application will not explain the control method and circuit connection in detail.

[0037] During operation, the laser processing equipment is powered on and started. The user first lifts the protective cover 2, which can be suspended at a height slightly higher than the workpiece thickness. The height of the protective cover 2 is limited by the protective cover limiter 7. The workpiece to be processed is placed on the worktable 1. As needed, accessories are used to fix the workpiece through the evenly distributed threaded holes on the surface of the worktable 1. The user manually controls the lifting and lowering of the machine head base 3 so that the distance value obtained by the laser rangefinder is the same as the working distance. The user connects to an external computer or other electronic device through the equipment interface to input the file or pattern to be laser processed. The main control board 9 controls the red laser source or blue laser source to output laser. The laser passes through the beam combining optical path module and the galvanometer assembly 101, and is emitted by the field lens assembly 105, which converges on the surface of the workpiece to be processed to achieve laser processing. During beam transmission, the main control board 9 controls the galvanometer assembly 101 to achieve two-dimensional deflection of the beam, so as to achieve the laser movement trajectory preset by the laser processing. During the preparation, processing and end stages, the corresponding working status is displayed on the display with graphics or text. During the preparation stage, the main control board 9 can control the blue laser source to output low-power blue laser light, which reaches the surface of the workpiece after passing through the aforementioned optical path. At this time, the workpiece surface will not be processed or damaged, realizing the preview function of the processing area and providing users with a visual display of the processing effect before the formal processing. During the laser emission process of the laser processing equipment, the user can pull down the protective cover 2 to the surface of the worktable 1. The locking part 8 will clamp the fastening screw 12 at the rear end of the protective cover 2 to prevent the protective cover 2 from rebounding due to the restoring force generated by the protective cover limiting part 7, thus sealing the entire processing area. This can protect the user's and observer's eyes from laser damage and also prevent the waste gas generated during the processing from polluting the environment. During the replacement of the field lens in the laser processing equipment, the user tightens the field lens into place with the galvanometer assembly 101 via the threaded interface. Depending on the model of the random field lens, the field lens identification contact 1012 is contacted at different positions, and the generated electrical signals are also different. The main control board 9 determines the model of the field lens or whether it is a field lens of another brand based on the different electrical signals, and adjusts it according to the judgment result and the pre-set working parameters of the processing equipment to achieve the working state. This reduces the number of manual input steps and improves the reliability of the laser processing equipment.
