Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and more specifically to a three-dimensional laser cutting and welding integrated device. Background Art

[0002] Three-dimensional laser cutting and welding is an advanced material processing technology that combines the advantages of laser cutting and laser welding. It can accurately cut and weld materials with three-dimensional structures. Compared with traditional two-dimensional laser processing, it has higher efficiency, precision and flexibility.

[0003] When traditional three-dimensional laser cutting and welding integrated equipment is used to weld materials, it is difficult for workers to control the length of welding time according to different materials. When the welding time is too long, the material will melt, thereby damaging the material to be welded. When the welding time is too short, the welding point will not be firm enough, resulting in poor welding quality. Therefore, the present invention provides a three-dimensional laser cutting and welding integrated equipment, which can reasonably control the length of welding time according to the thickness of the material to be welded, thereby ensuring the quality of welding. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a three-dimensional laser cutting and welding integrated equipment.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A three-dimensional laser cutting and welding integrated device, comprising a placement table, a movable frame mounted on the placement table, an annular groove formed inside the movable frame, a rotating ring slidably mounted inside the annular groove, and a welding module and a laser cutting module mounted on the inner wall of the rotating ring; A first electric push rod is also fixedly mounted on the inner wall of the rotating ring, a probe is fixedly mounted on one end of the first electric push rod away from the rotating ring, a baffle is sleeved on the outer surface of the probe, and the baffle is slidably connected to the probe through a groove provided on the probe, an infrared detection module is embedded on the outer surface of the probe away from the first electric push rod, a data processing module is mounted on the placement table, and the infrared detection module transmits the detected information to the data processing module; An electronic ruler is installed inside the baffle, and the other end of the electronic ruler is fixedly connected to the probe; An image acquisition module is embedded in one end of the probe away from the first electric push rod. The image acquisition module acquires images of the material placed on the placement table and transmits the acquired image information to the data processing module for processing.

[0007] Furthermore, a return spring for pushing the baffle to move is fixedly installed on one end of the baffle close to the first electric push rod, and the other end of the return spring is fixedly connected to the outer wall of the first electric push rod.

[0008] Furthermore, the data processing module compares the image information collected by the image collection module with the image information in the database to determine whether there is a weld on the material placed on the placement table.

[0009] Furthermore, the welding module includes a fixed frame installed on the inner side of the rotating ring, the fixed frame is connected and fixed to the rotating ring through a second electric push rod, the welding module also includes a rotating block rotatably connected to the fixed frame, a plurality of welding heads of different models are installed on the outer wall of the rotating block, a second drive motor is fixedly installed on the outside of the fixed frame, and the output end of the second drive motor is coaxially connected to the rotating block.

[0010] Furthermore, a control module is installed on the placement table, and the data processing module sends a signal to the control module. When the data processing module determines that there is a weld between the materials on the placement table, it sends a signal to the control module to control the welding module to work through the control module. When it is detected that there is no weld between the materials on the placement table, the data processing module sends another signal to the control module to control the laser cutting module to perform cutting operations through the control module.

[0011] Furthermore, the outer wall of the rotating ring is provided with a plurality of meshing teeth, and the outer wall of the movable frame is provided with a first driving motor, the output end of the first driving motor is coaxially connected with a driving gear, the driving gear passes through the movable frame and extends to the inside of the annular groove and meshes with the meshing teeth on the outer wall of the rotating ring.

[0012] Furthermore, the data processing module sends a signal to the control module based on the value measured by the electronic ruler, and the control module controls the rotation speed of the first drive motor. The control module is also used to control the rotation angle of the second drive motor. At the same time, the extension length of the first electric push rod and the second electric push rod are also controlled by the control module.

[0013] Furthermore, the data processing module calculates the thickness of the material to be welded using the following formula: ; Among them, Length is the thickness of the welding material, Lruler is the distance the electronic ruler is extended, L 固 It is the fixed distance between the infrared detection module and the extended end of the electronic ruler; When the length is less than or equal to 3 mm, the data processing module sends a signal to the control module to control the second drive motor to rotate so that the dedicated welding head for thin plate welding faces the material to be welded; When 3mm < Length < 12mm, the data processing module sends a signal to the control module to control the rotation of the second drive motor, causing the welding head dedicated to medium-thickness plates to face the material to be welded; When Length ≥ 12mm, the data processing module sends a signal to the control module to control the rotation of the second drive motor, causing the welding head dedicated to thick plates to face the material to be welded.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 8 A three-dimensional laser cutting and welding integrated equipment includes a placement table 1, a movable frame 101 is installed on the placement table 1, an annular groove 102 is opened inside the movable frame 101, a rotating ring 103 is slidably installed inside the annular groove 102, and a welding module 104 and a laser cutting module 105 are installed on the inner wall of the rotating ring 103; A first electric push rod 2 is also fixedly mounted on the inner wall of the rotating ring 103. A probe 201 is fixedly mounted on the end of the first electric push rod 2 away from the rotating ring 103. A baffle 202 is sleeved on the outside of the probe 201. The baffle 202 is slidably connected to the probe 201 through a groove provided on the probe 201. An infrared detection module 203 is embedded on the outside of the probe 201 away from the first electric push rod 2. A data processing module 106 is mounted on the placement table 1. The infrared detection module 203 transmits detected information to the data processing module 106. An electronic ruler 204 is installed inside the baffle 202, and the other end of the electronic ruler 204 is fixedly connected to the probe 201; An image acquisition module 205 is embedded in the end of the probe 201 away from the first electric push rod 2. The image acquisition module 205 acquires images of the material placed on the placement table 1. The image acquisition module 205 transmits the acquired image information to the data processing module 106 for processing. The data processing module 106 compares the image information acquired by the image acquisition module 205 with the picture information in the database to determine whether there is a weld on the material placed on the placement table 1.

[0020] By adopting the above technical solution, the staff first places the material to be processed on the placement table 1, and then the image acquisition module 205 captures the image of the material and sends it to the data processing module 106. At this time, the data processing module 106 can judge whether there is a gap on the material based on the image information. When it is judged that the material is a whole piece of material, it means that the material is the material to be cut. When it is judged that there is a welding seam on the material, it means that the material is the material to be welded. Then, a signal is sent to the control module 107 based on the judgment result.

[0021] A return spring 206 for pushing the baffle 202 to move is fixedly installed on one end of the baffle 202 close to the first electric push rod 2 , and the other end of the return spring 206 is fixedly connected to the outer wall of the first electric push rod 2 .

[0022] By adopting the above technical solution, the first electric push rod 2 can drive the probe 201 to move when working, thereby driving the push plate on the probe 201 to move. When the probe 201 is inserted into the welding seam, the push plate can be blocked by the material and stay outside the material. Thereafter, when the first electric push rod 2 drives the probe 201 to move, the probe 201 can move relative to the push plate. When the probe 201 moves, the infrared detection module 203 can detect the materials on both sides of the welding seam. When the infrared detection module 203 moves from one side of the material to be welded to the other side, due to the obstruction of the material, the data detected by the infrared detection module 203 will change. At this time, the infrared detection module 203 sends a signal to the data processing module 106, and the data processing module 106 sends a signal to the control module 107, so that the first electric push rod 2 stops working. At this time, the data processing module 106 can calculate the thickness of the material. After the calculation is completed, the data processing module 106 sends a signal to the control module 107, and the control module 107 controls the first electric push rod 2 to retract, thereby retracting the probe 201 from the welding seam.

[0023] The welding module 104 includes a fixed frame 1041 installed on the inner side of the rotating ring 103. When the rotating ring 103 rotates, it can drive the fixed frame 1041 to rotate. The fixed frame 1041 is connected and fixed to the rotating ring 103 through a second electric push rod 1045. The welding module 104 also includes a rotating block 1042 rotatably connected to the fixed frame 1041. A plurality of welding heads 1043 of different models are installed on the outer wall of the rotating block 1042. A second drive motor 1044 is fixedly installed on the outside of the fixed frame 1041, and the output end of the second drive motor 1044 is coaxially connected to the rotating block 1042.

[0024] By adopting the above technical solution, the second driving motor 1044 can drive the rotating block 1042 to rotate a certain angle when working, so that the welding heads 1043 of different types on the rotating block 1042 are aligned with the materials to be welded.

[0025] A control module 107 is also installed on the placement table 1. The data processing module 106 sends a signal to the control module 107. When the data processing module 106 determines that there is a weld seam between the materials on the placement table 1, it sends a signal to the control module 107 to control the welding module 104 to work. When it is detected that there is no weld seam on the materials on the placement table 1, the data processing module 106 sends another signal to the control to control the laser cutting module 105 to perform cutting operations through the control module 107.

[0026] A plurality of meshing teeth 108 are provided on the outer wall of the rotating ring 103, and a first driving motor 109 is installed on the outer wall of the moving frame 101. The output end of the first driving motor 109 is coaxially connected with a driving gear 110. The driving gear 110 penetrates through the moving frame 101 and extends into the annular groove 102 to mesh with the meshing teeth 108 on the outer wall of the rotating ring 103.

[0027] By adopting the above technical solution, when the first driving motor 109 works, it can drive the driving gear 110 to rotate. When the driving gear 110 rotates, it can drive the rotating ring 103 to rotate by meshing with the meshing teeth 108.

[0028] The data processing module 106 sends a signal to the control module 107 according to the value measured by the electronic ruler 204. The control module 107 controls the rotation speed of the first driving motor 109. The control module 107 is also used to control the rotation angle of the second driving motor 1044. At the same time, the first electric push rod 2 and the second electric push rod 1045 are also controlled by the control module 107 to control the extended length.

[0029] The data processing module 106 calculates the thickness of the material to be welded through the following formula: ; where, Length is the thickness of the welding material, Lruler is the extended distance of the electronic ruler 204, and L 固 is the fixed distance between the infrared detection module 203 and the extended end of the electronic ruler 204; When Length ≤ 3mm, the data processing module 106 sends a signal to the control module 107 to control the second driving motor 1044 to rotate, so that the special welding head 1043 for thin plate welding faces the material to be welded; When 3mm < Length < 12mm, the data processing module 106 sends a signal to the control module 107 to control the second driving motor 1044 to rotate, so that the special welding head 1043 for medium thickness plate welding faces the material to be welded; When Length ≥ 12mm, the data processing module 106 sends a signal to the control module 107 to control the second driving motor 1044 to rotate, so that the special welding head 1043 for thick plate welding faces the material to be welded.

[0030] When the data processing module 106 selects the welding head 1043 and finishes, it sends a signal to the control module 107 according to the welding head 1043, and the control module 107 controls the rotation speed of the first drive motor 109. The rotation speed of the first drive motor 109 is determined by the following formula: ; Wherein, S is the rotation speed of the first drive motor 109, S1 is the rotation speed of the first drive motor 109 when welding a material with a thickness of 1 mm, and G is the rotation speed of the first drive motor 109 that needs to be reduced for every 1 mm increase in the thickness of the material to be welded.

[0031] By adopting the above technical solution, the thicker the material to be welded, the longer the welding time required. At this time, the first drive motor 109 needs to drive the drive gear 110 to rotate slower, thereby ensuring that the welding head 1043 has sufficient time to weld the materials to be welded together.

[0032] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
