Description

Technical Field

[0001] The invention relates to the technical field of laser welding machines, in particular to a laser welding machine for metal material manufacturing. Background Art

[0002] Laser welding machine is a machine used for laser welding of materials. Laser welding uses laser to locally heat the metal material, melts the position to be welded by heating, and then welds the two metal parts together.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, reference Figures 1 to 4, is the first embodiment of the present invention, which provides a laser welding machine for metal material manufacturing, which can achieve automatic processing, low manual participation, and high processing speed. It includes a welding workbench 1, and a moving component 2 is arranged on the surface of the welding workbench 1. The moving component 2 has a laser welding component 3 installed on it. The moving component 2 can move horizontally and vertically. The component belongs to the conventional technical means of the existing laser welding machine, so it will not be described in detail. By starting the moving component 2, the laser welding component 3 can be driven to move horizontally and vertically, so that the metal material on the welding workbench 1 can be welded in multiple positions; The clamping part 4 includes a storage mechanism 401 arranged on the welding workbench 1. The storage mechanism 401 is used to place unprocessed metal pipes. A push rod motor 402 is installed inside the storage mechanism 401. A support frame 403 is installed at the output end of the push rod motor 402. When the push rod motor 402 is powered on, it can drive the support frame 403 to move up and down. When the laser welding machine is processing, the push rod motor 402 drives the support frame 403 to move upward to the surface processing area of ​​the welding workbench 1. When processing metal materials such as plates, it is necessary to ensure the flatness of the surface of the welding workbench 1. Therefore, the laser welding machine under this application can perform corresponding processing according to the metal pipe and the metal plate, and there will be no interference between the two. The push rod motor 402 drives the support frame 403 to pass through the placement slot 401 After the top of a is opened, the support frame 403 can be used to place and process the metal pipe. Linear drivers 404 are respectively installed at both ends of the surface of the support frame 403. A steering motor 407 is installed at the output end of the linear driver 404. A conical block 405 is installed at the output end of the steering motor 407. Two limit mechanisms 406 are installed on the surface of the support frame 403. The two linear drivers 404 are powered on to start the two steering motors 407 to rotate, so that the conical blocks 405 can be used to insert one end of the corresponding metal pipe, and then the two metal pipes can be pushed to merge, so that the metal pipe can be clamped without manual operation. After starting the steering motor 407, the conical block 405 can be rotated, and then the metal pipe can be rotated, which is convenient for laser welding.

[0032] Specifically, the storage mechanism 401 includes a placement slot 401a opened at the back of the welding workbench 1. It should be noted that the unprocessed metal pipes need to be placed side by side in the placement slot 401a corresponding to the two pipes to be processed, so that the clamping part 4 can clamp and position the two metal pipes to be welded at the same time. The placement slot 401a is provided with two openings, one opening is located at the back of the welding workbench 1, and this opening is mainly used to place the metal pipes to be welded, and the other opening is opened at the top of the welding workbench 1. a is arranged at an inclination, so that the metal pipe placed in the placement groove 401a can automatically move downward, and the placement groove 401a is provided with an assembly groove 401b, and the inner cavity of the assembly groove 401b is installed with a support rod 401c, and a guide frame 401d is movably installed at one end of the support rod 401c, and a return spring 401e is installed between the bottom of the guide frame 401d and the inner wall of the assembly groove 401b, and a blocking strip 401f is installed at the end of the placement groove 401a. The blocking strip 401f is made of rubber, has elasticity, and is located at the bottom of the placement groove 401a The two parallel metal pipes at the bottom will be blocked and limited by the guide frame 401d. When the push rod motor 402 drives the carrier frame 403 to move downward, the carrier frame 403 can use the limiting mechanism 406 to pull the guide frame 401d, so that the guide frame 401d will turn, and the rotating guide frame 401d will pull the return spring 401e, so that the unprocessed metal pipe limited by the guide frame 401d can automatically slide down to the carrier frame 403, and the other side of the guide frame 401d will release the position limit of the blocking strip 401f, so that the vertical The blocking strip 401f in the state blocks the subsequent unprocessed metal pipe fittings, and the function of automatic loading can be realized at this time. When the guide frame 401d is not limited in position by the limiting mechanism 406, the reset spring 401e pulled by the rotation of the guide frame 401d will shrink and reset, thereby driving the guide frame 401d to restore its position. At this time, one end of the guide frame 401d squeezes the blocking strip 401f again, and the metal pipe on the placement groove 401a rolls onto the guide frame 401d, thereby realizing the function of limiting the position of the metal pipe fittings again.

[0033] Furthermore, the limiting mechanism 406 includes a merging groove 406a provided on the outside of the carrier 403, the inner wall of the merging groove 406a is inlaid with a driving motor 406b, the driving motor 406b is an asynchronous motor, so the driving motor 406b can be driven in both clockwise and counterclockwise directions, and the output end of the driving motor 406b is installed with an adjusting rod 406c through a bearing, and a blocking plate 406d is installed at one end of the adjusting rod 406c, and an anti-skid pad 406e is provided at the bottom of the blocking plate 406d, and the anti-skid pad 406e is made of rubber, so the blocking plate 406d is connected to the merging groove 406a through the anti-skid pad 406e, and can be adjusted to the blocking plate 406d without external interference. The partition plate 406d is used for limiting. Since the limiting mechanism 406 is installed on the carrier frame 403 and two of them are provided, when the driving motor 406b on the limiting mechanism 406 located on the side of the guide frame 401d is started clockwise, the adjusting rod 406c can be driven to rotate, and the adjusting rod 406c synchronously drives the blocking plate 406d to move downward, so that the blocking plate 406d can be used to press down the top of the guide frame 401d, thereby driving the guide frame 401d to rotate, and then automatically replacing the metal pipe fittings that need to be processed. When the other limiting mechanism 406 is started, the metal pipe fittings that have been welded can be guided out of the carrier frame 403, thereby realizing the function of automatic loading and unloading.

[0034] In summary, the processing area of ​​the laser welding machine can choose two processing methods. When processing metal sheets, the welding workbench 1 can maintain a flat surface, so that the placement of the metal sheets will not be affected, and the metal sheets can be laser processed. When processing metal pipes, the positions of two metal pipes can be automatically limited, and then the laser welding process is convenient. There will be no interference between the two processing methods, which greatly improves the applicability of the laser welding machine. When laser welding metal pipes, a batch of metal pipes that need to be welded can be placed together. This avoids the inconvenience of manually placing metal pipes one by one during traditional laser welding, greatly improves the processing efficiency of metal pipes, and can automatically load and unload materials, with high overall work efficiency.

[0035] Example 2, reference Figure 1 , Figure 5 , Figure 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a protective part 10 of a laser welding machine for metal material manufacturing, which solves the problem that workers need to wear goggles and protective clothing. It includes a protective part 5, which includes a lifting mechanism 501. A filter cover 502 is installed on the outside of the lifting mechanism 501. The lifting mechanism 501 can drive the filter cover 502 to move up and down. The filter cover 502 is only opened at the bottom, and the other four sides and the top are closed. In this way, when the filter cover 502 moves up, the filter cover 502 is opened. When it moves down to the welding workbench 1, the processing area of ​​the welding workbench 1 can be fully sealed, so that the staff will not be harmed by the laser from any angle, and the safety is high. A blocking frame 503 is installed at the bottom of the filter cover 502, and a sealing ring 504 is arranged at the bottom of the blocking frame 503. The bottom of the filter cover 502 is fitted on the welding workbench 1 through the cooperation of the blocking frame 503 and the sealing ring 504. Since the sealing ring 504 is made of rubber, it has a higher fit and sealing performance, which can also reduce noise.

[0036] Specifically, the lifting mechanism 501 includes four support columns 501a arranged at the top corners of the welding workbench 1, wherein the inner cavities of two support columns 501a are provided with lifting motors 501b, the lifting motors 501b are asynchronous motors, and can be driven to rotate in both clockwise and counterclockwise directions, and the output end of the lifting motor 501b is provided with a lifting control rod 501c through a bearing, and the other two support columns 501a are provided with sliding rods 501d, and one end of the control rod 501c and the sliding rod 501d is provided with a lifting frame 501e, and the lifting frame 501e is provided with a lifting frame 501e. The interior of 1e is installed with the exterior of the filter cover 502. When the lifting motor 501b is driven clockwise, it cooperates with the sliding rod 501d to drive the lifting frame 501e to move upward, so that the filter cover 502 can be driven to move upward synchronously. Conversely, the filter cover 502 can be driven to move downward. In this way, when the movable filter cover 502 moves downward to close the processing area of ​​the welding workbench 1, it not only protects against laser hazards, but also achieves a dust-proof effect. At the same time, it can keep the processing area dry when the laser welding machine is out of use, which is beneficial to the long-term storage of the laser welding machine.

[0037] Furthermore, a guide tube 7 is installed on the outside of the support column 501a, and a lifting groove 8 is opened on the outside of the guide tube 7. A guide rod 9 is fixed to the inner cavity of the lifting groove 8, and a protective part 10 is installed on the outside of the guide rod 9. The protective part 10 can move up and down inside the guide tube 7 along the guide rod 9 on the lifting groove 8, and the above-mentioned components are arranged on the four surfaces of the top of the welding workbench 1. In this way, the protective part 10 can be used to protect the outside of the filter cover 502 on the welding workbench 1 to prevent the filter cover 502 from being damaged by external forces such as impact.

[0038] The protection part 10 includes a metal protection frame 1004, a movable hole 1001 is opened on the side wall of the protection frame 1004, shock-absorbing springs 1002 are installed on both sides of the inner wall of the movable hole 1001, and an movable bar 1003 with an arc-shaped inner wall is installed at one end of the shock-absorbing spring 1002, and the inner wall of the movable bar 1003 is in contact with the outer wall of the guide rod 9, and the protection frame 1004 is arranged outside the filter cover 502, and the bottom of the protection frame 1004 is in contact with the top of the blocking frame 503, so that when the filter cover 502 02 can automatically move up and down by driving the protective frame 1004 through the blocking frame 503 when it moves up and down, or it can be driven up and down by manual pulling. After the protective frame 1004 is hit, the shock-absorbing spring 1002 on the movable bar 1003 absorbs energy, and then releases the energy through the shock-absorbing spring 1002, so that a shock-absorbing effect can be achieved, which further improves the protection of the filter cover 502, and also improves the protection of the welding workbench 1.

[0039] The rest of the structure is the same as that of Example 1.

[0040] In summary, by using the filter cover 502, all-round laser protection can be achieved, and the staff does not need to wear goggles and protective clothing, which reduces the workload of the staff, and can also achieve dustproof and dry functions; The protection part 10 can be used to protect the filter cover 502 and the laser welding machine at the same time, thereby further improving the overall protection.

[0041] Example 3, reference Figure 1 , Figure 6 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a laser welding machine for metal material manufacturing, which solves the problem of dust removal of the laser welding machine and the processed parts. It includes a cleaning part 6, which includes a taking slot 601 opened in front of the welding workbench 1. The taking slot 601 is connected with the placement slot 401a and is arranged in an opposite inclined direction to the placement slot 401a, so that it is convenient to automatically lead out the processed metal pipe fittings. A fan 602 is installed on the top of the inner cavity of the taking slot 601. The fan 602 is powered on to start the fan 602. A filter component 603 is installed at the input end, a transmission pipe 604 is installed on one side of the filter component 603, and a cooling pipe 605 is installed on the top of the transmission pipe 604 passing through the welding workbench 1. The fan 602 can vacuum the processing area of ​​the welding workbench 1 through the cooperation of the filter component 603, the transmission pipe 604 and the cooling pipe 605, thereby realizing the surface cleaning of the welding workbench 1, and also realizing the cleaning of the processed parts, avoiding interference with laser processing, improving the quality of laser processing, and also performing air cooling on the processed parts and the laser welding machine to realize the function of cooling.

[0042] Specifically, the filter assembly 603 includes a combination frame 603a installed on the inner wall of the extraction slot 601, a positioning block 603b is installed on the outside of the combination frame 603a, a filter box 603c is installed at the bottom of the combination frame 603a, a magnet block 603d is embedded at the bottom of the filter box 603c, a separation net 603e is installed in the inner cavity of the filter box 603c, a sealing pad 603f is installed on the top of the filter box 603c, a retaining block 603g is installed on the outside of the filter box 603c, and a positioning frame 603h is movably installed on the outside of the retaining block 603g, and the positioning frame 603h can move the positioning block 603b by moving on the retaining frame 603g. By snapping together, the filter box 603c and the combination frame 603a can be combined. Both ends of the combination frame 603a and the filter box 603c are connected with the fan 602 and the transmission pipe 604. The metal debris absorbed by the fan 602 through the cooling pipe 605 will be transmitted to the transmission pipe 604, and the transmission pipe 604 will transmit the metal debris to the filter box 603c. The separation net 603e of the filter box 603c blocks the metal debris to prevent it from entering the fan 602. At the same time, the magnet block 603d is used to magnetically attract the metal debris, so that some tiny metal debris can be prevented from passing through the separation net 603e, thereby improving the metal debris collection effect.

[0043] The rest of the structure is the same as that of Example 2.

[0044] In summary, the processing area of ​​the welding workbench 1 is vacuumed, thereby achieving the cleaning of the surface of the welding workbench 1, and also achieving the cleaning of the workpiece, avoiding interference with the laser processing, improving the quality of the laser processing, and also air-cooling the workpiece and the laser welding machine to achieve the function of cooling; The metal debris can be collected and processed centrally and effectively, with good collection effect.

One is used to export the processed metal pipe, and the other is used to import the unprocessed metal pipe. Compared with manual import and export, the work is more stable and orderly. The transmission mechanism 11 is installed with a correction mechanism 12. The use of the correction mechanism 12 can be used to correct the position of the metal pipe that is offset during the transmission process to avoid the two ends of the metal pipe being non-parallel.

[0046] Specifically, the transmission mechanism 11 includes a load-bearing frame 1101 installed on the outer wall of the welding workbench 1, a shaping rod 1102 is installed inside the load-bearing frame 1101, a transmission frame 1103 is installed at one end of the shaping rod 1102, a conveying motor 1104 is installed in the inner cavity of the side wall of the transmission frame 1103, an output shaft 1105 is installed at the output end of the conveying motor 1104 through a bearing, a conveying belt 1106 is installed outside the output shaft 1105, and barrier strips 1107 are evenly installed outside the conveying belt 1106. The welding workbench 1 is located at the top of the transmission mechanism 11 and a latch 1108 is installed. A socket 1109 is opened on the surface of the load-bearing frame 1101, and the conveying motor 1104 is started by powering on. 4, the output shaft 1105 can be driven to rotate through the bearing, and then the conveyor belt 1106 can be driven to rotate synchronously. The conveyor belt 1106 cooperates with the barrier strip 1107 to transport the metal pipe fittings. The use of the barrier strip 1107 avoids the noise and damage caused by collision between the metal pipe fittings when they move. When the conveying mechanism 11 is not needed, the load-bearing frame 1101 can be pulled upward, and then the pin 1108 can be pulled and inserted into the socket 1109, thereby fixing the position of the conveying mechanism 11. At this time, the conveying mechanism 11 can also be used to close the openings of the taking slot 601 and the placing slot 401a, so as to prevent objects or organisms from entering the interior of the welding workbench 1.

[0047] The correction mechanism 12 includes a mounting frame 1201 arranged on the load-bearing frame 1101, a through hole 1202 is opened in the middle of the mounting frame 1201, a moving rod 1203 is installed in the inner cavity of the through hole 1202, a threaded cap 1204 is threadedly connected to the top of the moving rod 1203, a correction plate 1205 is installed at the bottom of the moving rod 1203, and a positioning spring 1206 is also installed on the moving rod 1203. When the transmission mechanism 11 moves, the top surface of the metal pipe will come into contact with the correction plate 1205, and the correction plate 1205 can be used to correct the deviation of the metal pipe. The corrected end can be corrected, and the corrected metal pipe can exert pressure on the correcting plate 1205 as a whole, which will squeeze the correcting plate 1205 to move upward. When the metal pipe passes through the correcting plate 1205, the pressure-applying ability of the positioning spring 1206 is utilized to move the correcting plate 1205 to the top of the next metal pipe again, thereby realizing correction one by one. For metal pipes of different weights, in order to ensure that the metal sheet can successfully squeeze open the correcting plate 1205, the threaded cap 1204 can be rotated to separate from the moving rod 1203, and then the positioning spring 1206 of corresponding strength can be selected.

[0048] The rest of the structure is the same as that of Example 3.

[0049] In summary, the transmission mechanism 11 can be used to achieve stable export and import of metal pipes, with good transportation stability, and avoid excessive export and import speeds that may cause impact damage to the laser welding machine body.

[0050] Working principle: 1. Before or during laser welding, the metal pipe can be placed in the storage mechanism 401 in advance. Precautions for placement: 1. Two metal pipes that need to be laser welded are placed side by side as a group; 2. A group of pipes must have the same size; 3. The total length of the two metal pipes cannot be greater than the distance between the two tapered blocks 405; 4. Two metal pipes need to be placed in the center; When two parallel metal pipes move downward along the placement groove 401a, they can directly roll onto the guide frame 401d, and the subsequent metal pipes are blocked by the blocking bar 401f. When the laser welding machine is processing, the drive motor 406b is started to drive clockwise, and the drive motor 406b drives the adjustment rod 406c to rotate. At this time, the blocking plate 406d on the adjustment rod 406c moves synchronously, so that the blocking plate 406d moves from the original vertical state to the horizontal state. When the blocking plate 406d moves horizontally, it will contact the top end of the guide frame 401d, and then the guide frame 401 d applies downward pressure, at this time the guide frame 401d can be rotated by the support rod 401c, and the reset spring 401e is stretched at the same time, and the rotated guide frame 401d will push the two metal pipes to move onto the carrier frame 403, and then the drive motor 406b is started again, and the drive motor 406b rotates counterclockwise at this time, which can drive the blocking plate 406d from horizontal to vertical. Since the anti-skid pad 406e is provided on the outside of the blocking plate 406d, the position of the blocking plate 406d can be limited by the extrusion of the anti-skid pad 406e and the merging groove 406a, and then according to the two The length of the metal pipe is determined by starting the linear drive 404 on the carrier 403 to drive the conical block 405 on the steering motor 407 to telescopically move, so that the metal pipe is inserted into the conical block 405, and then the two metal pipes are squeezed and fixed. At this time, the push rod motor 402 is started, and the push rod motor 402 drives the carrier 403 to move upward, and then passes through the placement slot 401a to enter the top construction area of ​​the welding workbench 1. At this time, the laser welding component 3 on the moving component 2 can be directly started to perform laser welding on the two metal pipes, and then the steering motor 407 is started to pass through the conical block 4 05 drives the metal pipe to rotate and weld. After welding is completed, the push rod motor 402 is started again. At this time, the carrier 403 is brought into the placement slot 401a, and then the drive motor 406b located on one side of the picking slot 601 is started, so that the blocking plate 406d at this position changes from vertical to horizontal. At this time, after the conical block 405 releases the metal pipe, the up and down movement of the carrier 403 brings about a shaking force to push the metal pipe to the picking slot 601. At this time, the picking slot 601 is used to guide the metal pipe out. The entire processing process has a high degree of automation, which realizes rapid processing and high processing efficiency. 2. During the transmission and processing of the metal pipe, the fan 602 is started, and the fan 602 conducts suction through the filter assembly 603, the transmission pipe 604, and the cooling pipe 605, thereby sucking in impurities such as metal debris. The sucked metal debris enters the combination frame 603a and the filter box 603c through the transmission pipe 604, and then the metal debris is blocked by the separation net 603e, and the metal debris is magnetically attracted by the magnet block 603d, thereby preventing the metal debris from entering the fan 602, and facilitating the centralized collection of the metal debris. 3. Power on and start the conveying motor 1104 inside the conveying frame 1103. The conveying motor 1104 can drive the output shaft 1105 to rotate and drive the conveying belt 1106 to convey. Then, the metal pipes are placed between the two barrier strips 1107 on the conveying belt 1106. The barrier strips 1107 are used to maintain the spacing between each group of metal pipes. In this way, the unprocessed metal pipes can be stably and orderly transferred to the placement slot 401a through the conveying mechanism 11, and then the subsequent processing is carried out, which further improves the processing automation. 4. Before the laser welding machine is used for welding, the lifting motor 501b inside the support column 501a is started, and the lifting motor 501b drives the control rod 501c to rotate clockwise, and then the lifting frame 501e is driven to move downward through the cooperation of the control rod 501c and the sliding rod 501d, and the filter cover 502 on the lifting frame 501e moves downward synchronously, and then when the sealing ring 504 at the bottom of the blocking frame 503 on the filter cover 502 contacts the surface of the welding workbench 1, the processing area of ​​the welding workbench 1 can be completely covered. At this time, no matter from which direction, the laser will not cause harm to the surrounding personnel, and the safety is good. In addition, as the blocking frame 503 moves downward, the protective frame 100 will also be driven synchronously. 4 moves downward, the protection frame 1004 can protect the filter cover 502 in real time, and after the protection frame 1004 is impacted by external force, it can also use the conduction of the shock-absorbing spring 1002 and the movable bar 1003 on the guide rod 9 to buffer, thereby reducing the impact and better protecting the filter cover 502. When the lifting motor 501b rotates counterclockwise, it can drive the filter cover 502 to move upward, and will also drive the protection frame 1004 to move upward synchronously, and the protection frame 1004 can also be manually lifted, which is convenient for lifting when the line of sight is disturbed, so that the user can observe the processing situation through the filter cover 502, thereby achieving the overall effect of dust prevention, keeping dry, and easy storage.
