Description

Technical Field

[0001] This invention relates to the field of laser processing technology, and in particular to a laser processing device for robot track processing. Background Technology

[0002] As a fundamental supporting component for the operation of industrial robots, the manufacturing quality of robot machining tracks directly affects the motion accuracy and operational stability of the robot system. With the continuous improvement of industrial automation, the demand for robot machining tracks continues to grow, and the requirements for their processing efficiency, processing accuracy, and processing flexibility are also increasing.

[0003] The manufacturing process of robotic tracks typically involves two key steps: first, cutting continuous raw track material into track segments of the required length; and second, welding auxiliary components such as connecting lugs and mounting brackets onto the track segments. Currently, these cutting and welding processes are mostly completed in steps on independent equipment. The cutting process usually employs mechanical cutting methods such as sawing and shearing, or thermal cutting methods such as plasma cutting and laser cutting; the welding process mostly uses methods such as arc welding, resistance welding, or laser welding. During operation, the track material must first be fed into the cutting equipment for a fixed-length cut, and then the cut track segments are transferred to the welding station, where manual labor or robotic arms assist in the positioning and welding of components such as connecting lugs. However, the existing technology has at least the following problems:

[0004] First, process separation leads to low production efficiency and extended production cycles. Cutting and welding are performed step-by-step on independent equipment, and the track segment requires repeated loading, unloading, and transfer operations between different processes. This not only increases auxiliary time but also increases buffer time and work-in-process inventory between processes, making it difficult to meet the needs of efficient continuous production. Second, multiple clamping and transfers affect processing accuracy. After cutting, the track segment needs to be repositioned and clamped when transferred to the welding equipment, and each repositioning introduces positioning errors. Especially for long robot-processed tracks, the cumulative errors caused by multiple clampings can significantly affect the welding position accuracy of components such as connecting ears on the track, and thus affect the matching accuracy between the track and the robot's walking mechanism. Third, existing cutting devices have insufficient accuracy when cutting long profiles. Mechanical sawing methods have defects such as wide kerf, large material loss, and poor cut end quality. Although ordinary laser cutting equipment can improve the kerf quality, it lacks a stable conveying and precise positioning mechanism for long track profiles. During continuous feeding, the track is prone to skew, leading to increased cutting length errors. Fourth, the flexibility of laser head spatial pose adjustment is limited in the welding process. Connecting lugs and other components typically need to be welded to specific locations on the sides or top of the track, requiring the laser head to precisely irradiate the weld from different angles. Existing devices often have limited laser head angle adjustment ranges, or complex adjustment mechanisms with slow response times, making it difficult to adapt to the processing needs of different track specifications and welding positions. Furthermore, cutting and welding functions often require separate laser heads, increasing equipment costs and changeover time. Fifth, the coordinated control of function switching and station transitions is challenging. Integrating cutting and welding into the same equipment requires switching between the laser head's cutting and welding modes, and simultaneously achieving automatic track segment transfer between multiple stations. Existing integrated solutions lack effective coordination design for the action connections between stations, easily leading to cycle time mismatches or positioning deviations. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention discloses a laser processing device that integrates the cutting and welding processes of robot processing tracks into the same equipment, achieves automatic track transport and precise positioning, possesses flexible adjustment capabilities of the laser head with multiple degrees of freedom, and features efficient collaboration among various workstations. The technical solution adopted by this invention is as follows: a laser processing device for robot processing tracks, comprising a main body mechanism for inputting and outputting the robot processing track to be processed, the main body mechanism including a processing box, a switching mechanism for switching between laser cutting and laser welding functions within the main body mechanism, and a laser mechanism for performing laser processing on the robot processing track on the switching mechanism;

[0006] The switching mechanism includes an inner support frame fixedly installed inside the processing box, a rotating bracket rotatably mounted on the inner support frame, and a transmission screw and a rotating square shaft rotatably mounted on the rotating bracket.

[0007] Furthermore, the main body mechanism includes a transverse moving rail groove disposed within the processing box, a transverse moving bracket slidably mounted within the processing box, a lower protruding column fixedly mounted at the bottom of the transverse moving bracket, the lower protruding column sliding within the transverse moving rail groove, a lower rotating rod rotatably mounted at the bottom of the lower rotating rod, a lower sliding groove provided at the end of the lower rotating rod, the transverse moving rail groove sliding within the lower sliding groove, a rotating block rotatably mounted at the bottom of the processing box, a lower electric cylinder fixedly mounted on the rotating block, the output end of the lower electric cylinder rotatably mounted with the lower rotating rod, and two robotic arms fixedly mounted within the processing box.

[0008] Furthermore, the main structure is divided into four areas: a feeding area, a transfer area, a discharge area, and a welding area. Each of the feeding area, transfer area, discharge area, and welding area is equipped with multiple conveying modules. The feeding area is located at the entrance end of the processing box, the discharge area is located next to the feeding area, the transfer area is located on the traversing bracket, and the welding area is located between two robotic arms.

[0009] Furthermore, the conveying module includes multiple conveying supports and multiple limiting supports. Conveying rollers are rotatably mounted on the conveying supports, and a conveying motor is fixedly mounted on the conveying supports. The conveying rollers are fixedly mounted to the motor shaft of the conveying motor. Two limiting side frames are slidably mounted on the limiting supports, and limiting screws are rotatably mounted on the limiting supports. The limiting side frames are provided with internal threads, and the limiting side frames and limiting screws form a threaded engagement. Limiting side rollers are rotatably mounted on the limiting side frames. The conveying supports and limiting supports of the conveying modules located in the transfer area are fixedly mounted on the transverse support, and the conveying supports and limiting supports of the conveying modules located in the feeding area, discharging area, and welding area are fixedly mounted on the processing box.

[0010] The entire robotic processing track to be processed enters from the loading area. The track sits on the conveyor rollers, driven by a conveyor motor. Rotating the limit screw adjusts the inner and outer positions of the limit side frames relative to the limit brackets, ensuring the two limit side rollers are in contact with both sides of the robotic processing track. The conveyor rollers transport the track, maintaining its straightness during transport thanks to the two limit side rollers. The track is then transferred to the conveyor rollers in the transfer area. Sensors in the transfer area detect when the track reaches the required length, stopping the conveyor motor in the loading area and halting the track transport. A laser mechanism then cuts the track, placing the required length in the transfer area and leaving the remaining track in the loading area. Subsequently, the lower electric cylinder extends, rotating the lower rotating rod relative to the processing box. This, via a sliding groove, causes the lower protruding column and the transverse support to slide along the processing box. The transverse support slides to the front of the welding area. The conveyor motor in the transfer area rotates, transporting the robot processing track from the transfer area to the welding area via the conveyor rollers. Then, the lower electric cylinder retracts, causing the lateral support to return to the front of the loading area. The laser mechanism then performs laser welding on the robot processing track in the welding area. The welded robot processing track is then sent out via the conveyor rollers in the welding area. The conveyor rollers in the loading area then transport the remaining robot processing track back to the transfer area. Similarly, the conveyor rollers in the transfer area transfer the robot processing track back to the welding area. When the length of the remaining robot processing track in the loading area is less than the required length, the conveyor rollers in the loading area transport all the robot processing track to the transfer area. The transfer area moves to the side of the discharge area, and the conveyor rollers in the transfer area rotate in the opposite direction, transporting the robot processing track from the transfer area to the conveyor rollers in the discharge area. The conveyor rollers in the discharge area then rotate, sending out the robot processing track. The next robot processing track to be cut is then placed on the conveyor rollers in the loading area, and this process repeats.

[0011] Furthermore, the switching mechanism also includes a top motor fixedly installed on the inner support frame, a motor gear fixedly installed on the motor shaft of the top motor, a rotating gear fixedly installed on the rotating bracket, the rotating gear meshing with the motor gear, and a fixing sleeve fixedly installed below the inner support frame.

[0012] Furthermore, the switching mechanism also includes a transmission column rotatably mounted on a rotating bracket, a passive belt wrapped around the transmission column and the fixed sleeve, an outer transmission wheel rotatably mounted on the rotating bracket, an upper bevel gear fixedly mounted below the outer transmission wheel, and a transmission belt wrapped around the outer transmission wheel and the transmission column.

[0013] Furthermore, the switching mechanism also includes a lead screw motor fixedly mounted on a rotating bracket, a transmission lead screw fixedly mounted to the motor shaft of the lead screw motor, an outer wheel rotatably mounted on the rotating bracket, a side bevel gear fixedly mounted on the outer wheel, the side bevel gear meshing with the upper bevel gear, a rotating shaft wheel fixedly mounted on the rotating square shaft, and a side transmission belt wound around the rotating shaft wheel and the outer wheel.

[0014] The top motor drives the motor gear to rotate, which in turn drives the rotating gear and rotating bracket to rotate. When the rotating bracket rotates, the fixed sleeve does not rotate, but the transmission column rotates along with the rotating bracket. The fixed sleeve drives the transmission column to rotate via a passive belt, which in turn drives the outer transmission wheel and upper bevel gear to rotate via a transmission belt. The upper bevel gear drives the side bevel gear and outer rotating wheel to rotate via a side transmission belt. The outer rotating wheel drives the rotating shaft wheel and rotating square shaft to rotate via a side transmission belt. The rotating square shaft drives the sliding bevel gear to rotate, which in turn drives the lower bevel gear and lower transmission wheel to rotate. The lower transmission wheel drives the rotating support column and lower rotating table to rotate via a lower transmission belt. This ensures that when the rotating bracket rotates, the lower rotating table rotates in the opposite direction to the rotation of the rotating bracket, so that the vertical plane of the lower rotating table always remains parallel to the vertical plane of the processing box. The lead screw motor drives the transmission lead screw to rotate, which drives the moving bracket to slide along the rotating bracket. When the moving bracket slides, the sliding bevel gear slides along the rotating square shaft.

[0015] Furthermore, the laser mechanism includes a movable bracket slidably mounted on a rotating bracket, a sliding bevel gear rotatably mounted on the movable bracket, the sliding bevel gear being slidably mounted to a rotating square shaft, a lower transmission wheel rotatably mounted on the movable bracket, a lower bevel gear fixedly mounted on the lower transmission wheel, the lower bevel gear meshing with the sliding bevel gear, a rotating support column rotatably mounted below the movable bracket, a lower transmission belt being wound around the rotating support column and the lower transmission wheel, and a lower rotating platform fixedly mounted below the rotating support column.

[0016] Furthermore, the laser mechanism also includes multiple upper rotating rods rotatably mounted below the lower rotating platform. A motor plate is rotatably mounted on the upper rotating rod, and a side moving plate is rotatably mounted on the other upper rotating rod. A lower rotating rod is rotatably mounted below the side moving plate and the motor plate. A lifting platform is rotatably mounted below the lower rotating rod. An adjusting motor is fixedly mounted on the motor plate, and an adjusting screw is rotatably mounted on the side moving plate via threaded transmission. The adjusting screw is fixedly mounted to the motor shaft of the adjusting motor.

[0017] Furthermore, the laser mechanism also includes an end block rotatably mounted below the lifting platform. A fine-tuning motor is fixedly mounted on the lifting platform, a fine-tuning gear is fixedly mounted on the motor shaft of the fine-tuning motor, an end gear is fixedly mounted on the end block, the fine-tuning gear meshes with the end gear, and a laser head is fixedly mounted on the end block.

[0018] Furthermore, the laser mechanism also includes a rotating collar rotatably mounted on the end block, a welding rod tube fixedly mounted on the rotating collar, a collar gear fixedly mounted on the rotating collar, a rotating motor fixedly mounted on the end block, a rotating gear fixedly mounted on the motor shaft of the rotating motor, and the rotating gear meshing with the collar gear.

[0019] The adjusting motor drives the adjusting screw to rotate, and the adjusting screw drives the side moving plate to move through the threaded transmission. The side moving plate drives the upper rotating rod to rotate relative to the lower rotating table, and the lower rotating rod to rotate relative to the lifting platform, thereby realizing the lifting and lowering of the lifting platform. The fine-tuning motor drives the fine-tuning gear to rotate, and the fine-tuning gear drives the end gear, end block and laser head to rotate, which can finely adjust the angle of the laser head. The rotating ring motor drives the rotating ring gear to rotate, and the rotating ring gear drives the collar gear, rotating collar and welding rod tube to rotate, thereby adjusting the feeding position of the welding wire.

[0020] When cutting the robot's processing track, the laser head is located at the junction of the loading area and the transfer area. At this time, the transmission screw drives the moving bracket to slide, and in conjunction with the rotation of the rotating bracket, the laser head performs laser cutting on the robot's processing track.

[0021] After the cutting is completed, the lead screw drives the moving bracket to the welding area. The robot places the connecting ears to be welded on both sides of the robot processing track. At this time, the lead screw drives the moving bracket to slide, and in conjunction with the rotation of the rotating bracket, the connecting ears are welded to both sides of the robot processing track by the laser head.

[0022] The beneficial effects of this invention compared with the prior art are: (1) This invention integrates the feeding area, transfer area, welding area and discharge area into the same processing box, and realizes the automatic flow of the robot processing track between the various areas by relying on the transverse support and the conveying module, realizing the full-process automated operation from the input of the whole track to cutting, welding and finished product output, realizing continuous production and effectively improving processing efficiency; (2) In the conveying module set by this invention, the adjustable limit side rollers are attached to both sides of the track to ensure that the long track remains straight during the conveying process, solving the problem of cutting length error caused by the skew of the long profile conveying. On the other hand, the special linkage design of the fixed sleeve, passive belt and transmission belt in the switching mechanism realizes that when the rotating bracket rotates, the lower rotating table rotates in the opposite direction to compensate, thereby ensuring that the vertical plane of the laser head is always parallel to the processing box, improving the quality of the cutting end face and the welding position. (3) The present invention accurately detects the track length by means of a sensor on the transfer area and drives the horizontal support to slide back and forth with the electric cylinder below. When the remaining track length in the loading area is less than the required cutting length, the device can automatically send all the remaining material to the transfer area and move it to the discharge area by the horizontal support to discharge it. At the same time, it automatically enters the processing cycle of the next track. (4) The present invention sets up a lifting adjustment component consisting of an upper rotating rod, an adjusting screw, a lifting platform, etc. in the laser mechanism, as well as an end block rotating component driven by a fine-tuning motor and a welding rod tube rotating component driven by a rotating ring motor. This enables the laser head to not only lift and lower, but also to make multi-angle fine adjustments. At the same time, the wire feeding position of the welding rod can also be adjusted independently. This enables the device to flexibly adapt to the welding requirements of different specifications of tracks and different positions of connecting ears. Moreover, the cutting and welding functions share the same laser head, reducing the changeover time and improving the versatility and flexibility of the equipment. Attached Figure Description

Detailed Implementation

[0034] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0035] Example: Reference Figures 1-10A laser processing device for processing robot tracks includes a main body mechanism for inputting and outputting robot processing tracks 4 to be processed. The main body mechanism includes a processing box 101. The main body mechanism is provided with a switching mechanism for switching between laser cutting and laser welding functions. The switching mechanism is provided with a laser mechanism for performing laser processing on the robot processing tracks 4.

[0036] The switching mechanism includes an inner support frame 201 fixedly installed inside the processing box 101, a rotating bracket 205 rotatably mounted on the inner support frame 201, and a transmission screw 218 and a rotating square shaft 215 rotatably mounted on the rotating bracket 205.

[0037] like Figures 3-5 As shown, the main mechanism includes a transverse moving rail groove 103 set in the processing box 101, a transverse moving bracket 102 slidably installed in the processing box 101, a lower protruding column 104 fixedly installed at the bottom of the transverse moving bracket 102, the lower protruding column 104 sliding in the transverse moving rail groove 103, a lower rotating rod 105 rotatably installed at the bottom of the lower rotating rod 105, a lower sliding groove 108 provided at the end of the lower rotating rod 105, the transverse moving rail groove 103 sliding in the lower sliding groove 108, a rotating block 107 rotatably installed at the bottom of the processing box 101, a lower electric cylinder 106 fixedly installed on the rotating block 107, the output end of the lower electric cylinder 106 rotatably installed with the lower rotating rod 105, and two robotic arms 109 fixedly installed in the processing box 101.

[0038] like Figures 3-5 As shown, the main structure is divided into four areas: a feeding area, a transfer area, a discharge area, and a welding area. Each of the feeding area, transfer area, discharge area, and welding area is equipped with multiple conveying modules. The feeding area is located at the entrance end of the processing box 101, the discharge area is located next to the feeding area, the transfer area is located on the traversing bracket 102, and the welding area is located between the two robotic arms 109.

[0039] like Figures 3-5As shown, the conveying module includes multiple conveying brackets 110 and multiple limiting brackets 113. Conveying rollers 112 are rotatably mounted on the conveying brackets 110, and a conveying motor 111 is fixedly mounted on the conveying brackets 110. The conveying rollers 112 are fixedly mounted to the motor shaft of the conveying motor 111. Two limiting side frames 115 are slidably mounted on the limiting brackets 113, and limiting screws 114 are rotatably mounted on the limiting brackets 113. The limiting side frames 115 are provided with internal threads, and the limiting side frames 115 and the limiting screws 114 form a threaded engagement. Limiting side rollers 116 are rotatably mounted on the limiting side frames 115. The conveying brackets 110 and limiting brackets 113 of the conveying module located in the transfer area are fixedly mounted on the transverse support 102. The conveying brackets 110 and limiting brackets 113 of the conveying modules located in the feeding area, discharging area, and welding area are fixedly mounted on the processing box 101.

[0040] The entire robotic processing track 4 to be processed enters from the loading area. The robotic processing track 4 is positioned on the conveying rollers 112. The conveying motor 111 drives the conveying rollers 112 to rotate. Rotating the limiting screw 114 adjusts the inner and outer positions of the limiting side frame 115 relative to the limiting bracket 113, causing the two limiting side rollers 116 to fit against both sides of the robotic processing track 4. The conveying rollers 112 transport the robotic processing track 4, ensuring it remains straight during transport through the two limiting side rollers 116. The conveying rollers 112 then transport the robotic processing track 4 to the conveying rollers 112 in the transfer area. Sensors are installed in the area. When the robot processing track 4 in the transfer area is detected to have reached the required length, the conveyor motor 111 in the loading area stops rotating, and the robot processing track 4 stops conveying. At this time, the robot processing track 4 is cut by a laser mechanism. The robot processing track 4 of the required length is located in the transfer area, and the remaining robot processing track 4 is located in the loading area. Then, the lower electric cylinder 106 extends, driving the lower rotating rod 105 to rotate relative to the processing box 101. The lower sliding groove 108 drives the lower protruding column 104 and the transverse support 102 to slide along the processing box 101. 02. The slide is moved to the front of the welding area. Then, the conveyor motor 111 of the transfer area rotates, and the robot processing track 4 of the transfer area is transported to the welding area via the conveyor roller 112. Then, the lower electric cylinder 106 retracts, causing the traversing bracket 102 to return to the front of the loading area. Then, the laser mechanism performs laser welding on the robot processing track 4 on the welding area. Then, the welded robot processing track 4 is sent out via the conveyor roller 112 of the welding area. Then, the conveyor roller 112 of the loading area transports the remaining robot processing track 4 back to the transfer area. Similarly, the conveyor roller 112 of the transfer area transports the remaining robot processing track 4 back to the transfer area. The robot processing track 4 is transferred to the welding area. When the length of the remaining robot processing track 4 in the feeding area is less than the required length, the conveying roller 112 of the feeding area conveys all the robot processing track 4 to the transfer area. The transfer area moves to the side of the discharge area, and the conveying roller 112 of the transfer area rotates in the opposite direction to convey the robot processing track 4 of the transfer area to the conveying roller 112 of the discharge area. Then the conveying roller 112 of the discharge area rotates to send out the robot processing track 4. Then the next robot processing track 4 to be cut is placed on the conveying roller 112 of the feeding area, and so on.

[0041] like Figures 6-8 As shown, the switching mechanism also includes a top motor 202 fixedly installed on the inner support frame 201. A motor gear 203 is fixedly installed on the motor shaft of the top motor 202. A rotating gear 204 is fixedly installed on the rotating bracket 205. The rotating gear 204 meshes with the motor gear 203. A fixing sleeve 206 is fixedly installed below the inner support frame 201.

[0042] like Figures 6-8 As shown, the switching mechanism also includes a transmission column 208 rotatably mounted on a rotating bracket 205. A passive belt 207 is wound around the transmission column 208 and the fixed sleeve 206. An external transmission wheel 210 is rotatably mounted on the rotating bracket 205. An upper bevel gear 211 is fixedly mounted below the external transmission wheel 210. A transmission belt 209 is wound around the external transmission wheel 210 and the transmission column 208.

[0043] like Figures 6-8 As shown, the switching mechanism also includes a lead screw motor 217 fixedly mounted on the rotating bracket 205, a transmission lead screw 218 fixedly mounted on the motor shaft of the lead screw motor 217, an outer rotating wheel 213 rotatably mounted on the rotating bracket 205, a side bevel gear 212 fixedly mounted on the outer rotating wheel 213, the side bevel gear 212 meshing with the upper bevel gear 211, a rotating shaft wheel 216 fixedly mounted on the rotating square shaft 215, and a side transmission belt 214 wound around the rotating shaft wheel 216 and the outer rotating wheel 213.

[0044] The top motor 202 drives the motor gear 203 to rotate. The motor gear 203 drives the rotating gear 204 and the rotating bracket 205 to rotate. When the rotating bracket 205 rotates, the fixed sleeve 206 does not rotate, but the transmission column 208 rotates with the rotating bracket 205. The fixed sleeve 206 drives the transmission column 208 to rotate via the driven belt 207. The transmission column 208 drives the outer transmission wheel 210 and the upper bevel gear 211 to rotate via the transmission belt 209. The upper bevel gear 211 drives the side bevel gear 212 and the outer rotating wheel 213 to rotate. The outer rotating wheel 213 drives the rotating shaft wheel 216 and the rotating square shaft 215 to rotate via the side transmission belt 214. The rotating square shaft 215 drives the sliding... The bevel gear 302 rotates, and the sliding bevel gear 302 drives the lower bevel gear 304 and the lower transmission wheel 303 to rotate. The lower transmission wheel 303 drives the rotating support 306 and the lower rotating table 307 to rotate through the lower transmission belt 305. This ensures that when the rotating support 205 rotates, the lower rotating table 307 rotates in the opposite direction to the rotation of the rotating support 205, so that the vertical surface of the lower rotating table 307 is always parallel to the vertical surface of the processing box 101. The lead screw motor 217 drives the transmission lead screw 218 to rotate, and the transmission lead screw 218 drives the moving support 301 to slide along the rotating support 205. When the moving support 301 slides, the sliding bevel gear 302 slides along the rotating square axis 215.

[0045] like Figure 9 , Figure 10As shown, the laser mechanism includes a movable support 301 slidably mounted on a rotating support 205. A sliding bevel gear 302 is rotatably mounted on the movable support 301 and is slidably mounted on a rotating square shaft 215. A lower transmission wheel 303 is rotatably mounted on the movable support 301, and a lower bevel gear 304 is fixedly mounted on the lower transmission wheel 303. The lower bevel gear 304 meshes with the sliding bevel gear 302. A rotating support column 306 is rotatably mounted below the movable support 301. A lower transmission belt 305 is wound around the rotating support column 306 and the lower transmission wheel 303. A lower rotating platform 307 is fixedly mounted below the rotating support column 306.

[0046] like Figure 9 , Figure 10 As shown, the laser mechanism also includes multiple upper rotating rods 308 rotatably mounted below the lower rotating platform 307. A motor plate 311 is rotatably mounted on the upper rotating rod 308. A side moving plate 309 is rotatably mounted on the other side of the upper rotating rod 308. A lower rotating rod 310 is rotatably mounted below the side moving plate 309 and the motor plate 311. A lifting platform 313 is rotatably mounted below the lower rotating rod 310. An adjusting motor 312 is fixedly mounted on the motor plate 311. An adjusting screw 324 is rotatably mounted on the side moving plate 309 via threaded transmission. The adjusting screw 324 is fixedly mounted to the motor shaft of the adjusting motor 312.

[0047] like Figure 9 , Figure 10 As shown, the laser mechanism also includes an end block 316 rotatably mounted below the lifting platform 313. A fine-tuning motor 314 is fixedly mounted on the lifting platform 313. A fine-tuning gear 315 is fixedly mounted on the motor shaft of the fine-tuning motor 314. An end gear 317 is fixedly mounted on the end block 316. The fine-tuning gear 315 meshes with the end gear 317. A laser head 323 is fixedly mounted on the end block 316.

[0048] like Figure 9 , Figure 10 As shown, the laser mechanism also includes a rotating collar 318 rotatably mounted on the end block 316. A welding rod tube 319 is fixedly mounted on the rotating collar 318. A collar gear 322 is fixedly mounted on the rotating collar 318. A rotating motor 320 is fixedly mounted on the end block 316. A rotating gear 321 is fixedly mounted on the motor shaft of the rotating motor 320. The rotating gear 321 meshes with the collar gear 322.

[0049] The adjusting motor 312 drives the adjusting screw 324 to rotate. The adjusting screw 324 drives the side moving plate 309 to move through the threaded transmission. The side moving plate 309 drives the upper rotating rod 308 to rotate relative to the lower rotating platform 307. The lower rotating rod 310 rotates relative to the lifting platform 313, thereby realizing the lifting of the lifting platform 313. The fine-tuning motor 314 drives the fine-tuning gear 315 to rotate. The fine-tuning gear 315 drives the end gear 317, end block 316 and laser head 323 to rotate, which can finely adjust the angle of the laser head 323. The rotating ring motor 320 drives the rotating ring gear 321 to rotate. The rotating ring gear 321 drives the collar gear 322, rotating collar 318 and welding rod tube 319 to rotate, thereby adjusting the feeding position of the welding wire.

[0050] When cutting the robot processing track 4, the laser head 323 is located at the junction of the loading area and the transfer area. At this time, the transmission screw 218 drives the moving bracket 301 to slide, and in conjunction with the rotation of the rotating bracket 205, the laser head 323 performs laser cutting on the robot processing track 4.

[0051] After the cutting is completed, the transmission screw 218 drives the moving bracket 301 to the welding area. The robot arm 109 places the connecting ears to be welded on both sides of the robot processing track 4. At this time, the transmission screw 218 drives the moving bracket 301 to slide, and in conjunction with the rotation of the rotating bracket 205, the connecting ears are welded to both sides of the robot processing track 4 by the laser head 323.

[0052] Working principle: The entire robotic processing track 4 to be processed enters from the loading area and is positioned on the conveying rollers 112. The conveying motor 111 drives the conveying rollers 112 to rotate. The rotating limit screw 114 adjusts the inner and outer positions of the limit side frame 115 relative to the limit bracket 113, so that the two limit side rollers 116 are in contact with both sides of the robotic processing track 4. The conveying rollers 112 transport the robotic processing track 4, and the two limit side rollers 116 keep the robotic processing track 4 straight during transport. The conveying rollers 112 transport the robotic processing track 4 to the conveying rollers 112 in the transfer area. Sensors are installed in the transfer area. When the sensors detect that the robotic processing track 4 in the transfer area has reached the required level, the conveying motor 111 in the loading area stops rotating, and the robotic processing track 4 stops being transported.

[0053] The top motor 202 drives the motor gear 203 to rotate. The motor gear 203 drives the rotating gear 204 and the rotating bracket 205 to rotate. When the rotating bracket 205 rotates, the fixed sleeve 206 does not rotate, but the transmission column 208 rotates with the rotating bracket 205. The fixed sleeve 206 drives the transmission column 208 to rotate via the driven belt 207. The transmission column 208 drives the outer transmission wheel 210 and the upper bevel gear 211 to rotate via the transmission belt 209. The upper bevel gear 211 drives the side bevel gear 212 and the outer rotating wheel 213 to rotate. The outer rotating wheel 213 drives the rotating shaft wheel 216 and the rotating square shaft 215 to rotate via the side transmission belt 214. The rotating square shaft 215 drives the sliding... The bevel gear 302 rotates, and the sliding bevel gear 302 drives the lower bevel gear 304 and the lower transmission wheel 303 to rotate. The lower transmission wheel 303 drives the rotating support 306 and the lower rotating table 307 to rotate through the lower transmission belt 305. This ensures that when the rotating support 205 rotates, the lower rotating table 307 rotates in the opposite direction to the rotation of the rotating support 205, so that the vertical surface of the lower rotating table 307 is always parallel to the vertical surface of the processing box 101. The lead screw motor 217 drives the transmission lead screw 218 to rotate, and the transmission lead screw 218 drives the moving support 301 to slide along the rotating support 205. When the moving support 301 slides, the sliding bevel gear 302 slides along the rotating square axis 215. The adjusting motor 312 drives the adjusting screw 324 to rotate. The adjusting screw 324 drives the side moving plate 309 to move through the threaded transmission. The side moving plate 309 drives the upper rotating rod 308 to rotate relative to the lower rotating platform 307. The lower rotating rod 310 rotates relative to the lifting platform 313, thereby realizing the lifting of the lifting platform 313. The fine-tuning motor 314 drives the fine-tuning gear 315 to rotate. The fine-tuning gear 315 drives the end gear 317, end block 316 and laser head 323 to rotate, which can finely adjust the angle of the laser head 323. The rotating ring motor 320 drives the rotating ring gear 321 to rotate. The rotating ring gear 321 drives the collar gear 322, rotating collar 318 and welding rod tube 319 to rotate, thereby adjusting the feeding position of the welding wire.

[0054] At this time, the robot processing track 4 is cut by the laser mechanism. When the robot processing track 4 is being cut, the laser head 323 is located at the junction of the loading area and the transfer area. At this time, the transmission screw 218 drives the moving bracket 301 to slide, and in conjunction with the rotation of the rotating bracket 205, the laser head 323 performs laser cutting on the robot processing track 4. After cutting, the required length of the robot processing track 4 is located on the transfer area, and the remaining length of the robot processing track 4 is located on the loading area. Then, the lower electric cylinder 106 extends, driving the lower rotating rod 105 to rotate relative to the processing box 101. Through the sliding groove 108, the lower protruding column 104 and the transverse support 102 slide along the processing box 101. The transverse support 102 slides to the front of the welding area. Then, the conveyor motor 111 of the transfer area rotates, and the robot processing track 4 of the transfer area is transported to the welding area through the conveyor roller 112. Then, the lower electric cylinder 106 retracts, causing the transverse support 102 to return to the front of the loading area. Then, the laser mechanism performs laser welding on the robot processing track 4 on the welding area. After the cutting is completed, the transmission screw 218 drives the moving bracket 301 to move to the welding area. The robot arm 109 places the connecting ears to be welded on both sides of the robot processing track 4. At this time, the transmission screw 218 drives the moving bracket 301 to slide, and in conjunction with the rotation of the rotating bracket 205, the connecting ears are welded to both sides of the robot processing track 4 by the laser head 323. The welded robotic processing track 4 is then conveyed out by the conveyor rollers 112 in the welding area. The remaining robotic processing track 4 is then conveyed to the transfer area by the conveyor rollers 112 in the loading area. Similarly, the transfer area conveyor rollers 112 transfer the robotic processing track 4 back to the welding area. When the length of the remaining robotic processing track 4 in the loading area is less than the required length, the loading area conveyor rollers 112 convey all of the robotic processing track 4 to the transfer area. The transfer area moves to the side of the discharge area, and the transfer area conveyor rollers 112 rotate in the opposite direction, conveying the robotic processing track 4 from the transfer area to the discharge area conveyor rollers 112. The discharge area conveyor rollers 112 then rotate, sending out the robotic processing track 4. The next robotic processing track 4 to be cut is then placed on the loading area conveyor rollers 112, and this process is repeated.
