[0038] Specifically, the positioning device 7 includes two upright plates 701, which are located on both sides of the conveying mechanism 3 and are positioned opposite each other. Each upright plate 701 is fixedly provided with a flipping seat 702, and a rotating shaft 703 is rotatably provided on the flipping seat 702.

A flipping cylinder 707 is also hinged to the upright plate 701, and the output end of the flipping cylinder 707 is hinged to the connecting seat 706.

[0039] The working process of this embodiment is as follows: Before the device starts working, the feed sensor 309 and the discharge sensor 310 on the conveying mechanism 3 will perform detection. When the discharge sensor 310 does not detect the middle tube 8 but the feed sensor 309 detects the middle tube 8, the conveying mechanism 3 will move. When the material bar moves to the point where the discharge sensor 310 detects the middle tube 8, it will stop moving. At the same time that the chain 306 stops moving, the feeding mechanism 2 will transfer the middle tube 8 to the conveying mechanism 3, the unloading mechanism 6 will remove the middle tube 8 from the conveying mechanism 3, the adjustment mechanism 41 will adjust the angle of the middle tube 8, the positioning device 7 will position the chain plate 307, the marking mechanism 5 will mark the middle tube 8, and the reset mechanism 42 will reset the middle tube 8 after it has been marked.

[0040] When the feeding mechanism 2 is feeding material, the feeding motor 206 mounted on the feeding rack 204 will start. After the feeding motor 206 starts, it will drive the drive wheel 208 to rotate. The rotation of the drive wheel 208 will drive the transmission belt 213 and the driven wheel 212 to rotate. The transmission belt 213 will drive the feeding slide 207 to move along the feeding rail 205. When the feeding slide 207 moves above the unloading seat 201 and the bracket 203, the feeding lifting cylinder 211 will extend, pushing the feeding mounting plate 209 to move down, and the material will be fed. When the mounting plate 209 moves down, the feeding guide rod 210 connected to the feeding mounting plate 209 will also move to ensure the stability of the feeding mounting plate 209 during movement. At the same time, the feeding adjustment cylinder 215 will also drive the feeding adjustment frame 217 to move along the feeding adjustment rail 216 to adjust the position of the feeding clamp 214 so that the feeding clamp 214 is aligned with the middle limb tube 8. As the feeding lifting cylinder 211 continues to extend, it can accurately grab the middle limb tube 8 placed on the feeding seat 201 and the bracket 203.

[0041] After the feeding clamp 214 grabs the middle tube 8, the positioning frame on the unloading seat 201 will be released. Then the feeding lifting cylinder 211 will shorten, driving the feeding mounting plate 209 to move upward. The middle tube 8 will also move upward under the clamp of the feeding clamp 214. When the feeding lifting cylinder 211 shortens to its limit distance, the feeding motor 206 will drive the feeding slide 207 to move in the opposite direction. When the feeding slide 207 moves above the transmission device, it will stop. Then the feeding lifting cylinder 211 will extend, pushing the feeding mounting plate 209 to move downward. At the same time, the feeding adjusting cylinder 215 will drive the feeding adjusting frame 217 to move along the feeding adjusting rail 216 again to adjust the position of the middle tube 8 held by the feeding clamp 214 until it is aligned with the feeding clamp 311 of the conveying mechanism 3.

[0042] When the extended loading lifting cylinder 211 drives the middle limb tube 8 into the feeding clamp 311, the middle limb tube 8 will be clamped by the feeding clamp 311, and the loading clamp 214 will be released at the same time. Then the loading lifting cylinder 211 will shorten and drive the loading clamp 214 to move upward. When the loading lifting cylinder 211 retracts back to the limit position, the loading motor 206 will drive the loading slide 207 to move above the unloading seat 201 and the bracket 203 to prepare for loading again.

[0043] During adjustment, the adjusting cylinder 402 mounted on the base 401 pushes the mounting bracket 404 on the adjusting track 403 to move along the adjusting track 403, so that the snap-fit ​​connector 406 on the mounting bracket 404 matches and fits with the end of the middle limb tube 8. The middle limb tube 8 moves towards the blocking frame 407 under the push of the snap-fit ​​connector 406, and the other end of the middle limb tube 8 fits with the rotating seat 408 on the blocking frame 407. Then the rotating motor 405 rotates, driving the middle limb tube 8 to rotate at a set angle through the snap-fit ​​connector 406. After the angle of the middle limb tube 8 is adjusted, the adjusting cylinder 402 shortens, driving the mounting bracket 404 to move backward, so that the snap-fit ​​connector 406 separates from the end of the middle limb tube 8 and resets.

[0044] When positioning device 7 is in use, the tilting cylinder 707 mounted on the upright plate 701 will extend, pushing the free end of the connecting seat 706 to move. Since the connecting seat 706 is fixedly connected to the rotating shaft 703, the movement of the free end of the connecting seat 706 will drive the rotating shaft 703 to rotate. After the rotating shaft 703 rotates, the rotating block 704 fixed on the rotating shaft 703 will drive the locking block 705 to engage in the slot on the chain plate 307, thus positioning the chain plate 307. When the laser marking head 507 completes marking, the tilting cylinder 707 will shorten, driving the rotating shaft 703 to rotate in the opposite direction. The locking block 705 will move out of the slot, allowing the chain plate 307 to move with the chain 306.

[0045] Before marking, the marking mechanism 5 can adjust the height of the fixed plate 504 by adjusting the adjustment handle 503 on the adjustment module 502 according to the power of the laser marking head 507 and the material to be processed. This will drive the electric cylinder 505 installed on the fixed plate 504 to move, thereby adjusting the distance between the laser marking head 507 at the output end of the electric cylinder 505 and the middle limb tube 8, so that the height of the laser marking head 507 meets the marking requirements. Then, the content to be marked is input through the control host 506.

[0046] A mounting base 501 is provided between the adjustment module 502 and the base 1 to increase the height of the adjustment module 502. This can prevent the distance that the laser marking head 507 needs to adjust from exceeding the adjustment range of the adjustment module 502, and also reduce costs.

[0047] When the marking mechanism 5 is marking, the clamping cylinder 509 on the support frame 508 will extend and push the clamping push plate 510 to move along the clamping slide rail 511. The clamping push plates 510 on both sides of the transmission mechanism will move simultaneously and clamp the middle limb tube 8 that has moved between the clamping push plates 510. Then, the laser marking head 507 will emit a laser beam 512 to mark the middle limb tube 8. At the same time, the electric cylinder 505 will also extend to adjust the position of the laser marking head 507. When the marking is completed, the laser beam 512 on the laser marking head 507 will disappear. At the same time, the electric cylinder 505 will shorten and drive the laser marking head 507 to reset. The two clamping cylinders 509 on the support frame 508 will also shorten simultaneously, causing the two clamping push plates 510 to move towards each other and release the clamping and fixing of the middle limb tube 8.

[0048] When resetting, the working process of the reset mechanism 42 is the same as that of the adjustment mechanism 41. The only difference is that the rotation direction of the motor 405 of the reset mechanism 42 is opposite to that of the motor 405 of the adjustment mechanism 41, so that the middle limb tube 8 is restored to the state before adjustment, which facilitates the subsequent processing.

[0049] When the discharge sensor 310 on the transmission mechanism detects the middle limb tube 8, the unloading mechanism 6 will unload the material.

[0050] When the unloading mechanism 6 is unloading, the unloading cylinder 611 mounted on the unloading frame 601 extends, pushing the unloading slide 603 to move above the conveying mechanism 3. Then, the unloading lifting cylinder 604 extends, pushing the unloading mounting plate 606 downward. When the unloading mounting plate 606 moves downward, the unloading guide rod 605 also moves synchronously to ensure the stability of the unloading mounting plate 606. At the same time, the unloading adjusting cylinder 612 also drives the unloading adjusting frame 607 to move along the unloading adjusting rail 608 to adjust the position of the unloading clamp 609. After the unloading clamp 609 is aligned with the middle leg tube 8, The marked middle tube 8 is removed from the feeding clamp 311 on the transmission mechanism. Then, the unloading lifting cylinder 604 will shorten, causing the unloading mounting plate 606 to move upward. After the unloading mounting plate 606 moves upward, the unloading cylinder 611 will also shorten, causing the unloading slide 603 to move in the opposite direction along the unloading rail 602. When the unloading slide 603 moves above the discharge trough 610, the unloading lifting cylinder 604 will extend again. When the unloading lifting cylinder 604 extends to its limit, the unloading clamp 609 will release, allowing the marked middle tube 8 to fall into the discharge trough 610 to complete the unloading.
