Description
Technical Field
[0001] This utility model belongs to the technical field of shearing devices, specifically an SMT strip shearing device with a waste collection function. Background Technology
[0002] The SMT tape cutting device is an automated equipment designed specifically for surface mount technology (SMT). It is primarily used for precisely cutting electronic component tapes (such as resistors, capacitors, and chips) and is equipped with a recycling system for the scrap tape after cutting. Its core structure includes a conveyor belt, a cutting mechanism (including hydraulic rods and electrically operated telescopic rods to drive the cutter), a pressing frame (ensuring a smooth cut), and a recycling system (an anti-static recycling box or vacuum adsorption device). Through high-precision positioning and automated cutting, this device solves the problems of low efficiency and easy jamming associated with traditional manual cutting, significantly improving the 5S management level of the production site. Its application areas cover high-density electronic manufacturing scenarios such as mobile phones, computers, automotive electronics, and 5G base stations. It is particularly suitable for the tape recycling process of placement machines such as those used by Samsung and Yamaha, helping companies achieve intelligent and unmanned production. Existing SMT tape cutting devices mostly rely on manual cleaning of waste tape, lacking an automatic collection system. This results in waste material scattering, jamming equipment, or mixing into the good product area, which not only affects production efficiency and 5S management, but may also cause component contamination due to electrostatic adsorption, increasing rework costs and quality risks. Summary of the Invention
[0003] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides an SMT tape cutting device with a waste collection function, which effectively solves the problem that existing SMT tape cutting devices rely on manual cleaning of waste tape and lack an automatic collection system, resulting in waste scattering, equipment jamming, or mixing into the good product area, affecting production efficiency.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an SMT strip cutting device with waste self-collection function, including a workbench, a support frame fixedly installed on the upper part of the workbench, a hydraulic cylinder fixedly installed on the top of the support frame, the transmission end of the hydraulic cylinder penetrating downward into the interior of the support frame and fixedly installed with a cutting blade, a collection box fixedly installed at the bottom of the workbench, a discharge valve fixedly installed at the bottom of the collection box, and a placement platform fixedly installed in the middle of the top of the workbench, with two baffles provided inside the placement platform; Both baffles are equipped with cleaning strips on their upper parts. A servo motor is fixedly installed on the rear side of the top of the workbench via a support plate. The output end of the servo motor is equipped with a transmission component, which is connected to the two baffles and the two cleaning strips. When the servo motor is running, it drives the two baffles and the two cleaning strips to clean up the waste material through the transmission component.
[0005] Preferably, a slide rod is fixedly installed at one end of the upper part of the shearing blade, and a sliding sleeve is fixedly installed on the rear side of the top of the support frame, with the slide rod inserted inside the sliding sleeve.
[0006] Preferably, the transmission assembly includes a drive sprocket fixedly installed at the output end of the servo motor, a first gear fixedly installed on one side of the drive sprocket, one side of the first gear being rotatably connected to the placement platform, and a second gear meshing with the circumferential surface of the first gear.
[0007] Preferably, the surface of the driving sprocket is engaged with a chain, one end of the chain is engaged with a driven sprocket, and one side of the driven sprocket is rotatably connected to the top of the worktable via a positioning seat.
[0008] Preferably, a shaft is fixedly installed on one side of both the second gear and the driven sprocket. One end of each shaft extends into the interior of the placement platform, and one end of each shaft surface is rotatably connected to the placement platform via a bushing. Rotating shafts are rotatably installed on both sides of the inner wall of one side of the placement platform. The two ends of the two baffles on opposite sides are fixedly connected to the surfaces of the two shafts and the two rotating shafts, respectively.
[0009] Preferably, a lead screw is rotatably installed inside each of the two baffles. A first bevel gear is fixedly installed at the ends of the two lead screws that are far apart from each other through a rotating rod. The surfaces of the two rotating rods are rotatably connected to the inside of the baffles through bearings. A second bevel gear is meshed with one side of the surface of the first bevel gear. Both sides of the two second bevel gears are fixedly connected to the inner wall of the placement platform through a fixing bracket.
[0010] Preferably, the surface of the lead screw is threaded with a threaded sleeve, and the lower part of the threaded sleeve is fixedly installed with a connecting bracket through a connecting rod. The upper part of the two connecting brackets is fixedly connected to the two ends of the two cleaning strips respectively.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator places the SMT strip on the two baffles, and then starts the hydraulic cylinder to drive the shearing blade to move down. When the shearing blade moves down, it drives the slide rod to slide in the sliding sleeve, which increases the stability of the shearing blade movement. When the shearing blade moves down, it will cut the SMT strip. Then, the operator takes away the cut SMT strip and starts the servo motor at the same time. When the servo motor runs, it drives the first gear to rotate through the drive sprocket. When the first gear rotates, it drives the second gear to rotate. When the drive sprocket rotates, it drives the driven sprocket to rotate through the chain. When the driven sprocket and the second gear rotate, they drive the two baffles to rotate downward through the two shafts. When the two baffles rotate, they rotate along the two shafts, which improves the stability of the rotation of the two baffles. When the two baffles rotate downward, they will dump the waste material on top into the collection box. When the two baffles rotate in opposite directions, they drive the two first bevel gears to rotate along the surfaces of the two second bevel gears. Through the meshing between the two, the first bevel gears can rotate on their own axis. When the first bevel gears rotate, they drive the lead screw to rotate through the rotating rod. When the two lead screws rotate, they drive the two lead sleeves to move rapidly in opposite directions. When the two lead sleeves move rapidly in opposite directions, they drive the two cleaning strips to move rapidly through the two connecting rods and two connecting frames. This scrapes the waste material adsorbed on the upper part of the two baffles into the inside of the collection box for collection. This allows the SMT tape cutting device to quickly and conveniently clean and collect waste material, avoiding waste scattering and equipment jamming, thereby improving production efficiency.

[0015] Depend on Figures 1 to 7 The present invention includes a workbench 1, a support frame 2 fixedly installed on the upper part of the workbench 1, the support frame 2 being used to install a shearing device, a hydraulic cylinder 3 fixedly installed on the top of the support frame 2, the hydraulic cylinder 3 being able to output vertical power, the transmission end of the hydraulic cylinder 3 penetrating downward into the interior of the support frame 2 and fixedly installed with a shearing blade 4, the shearing blade 4 being able to cut SMT material strips, a collection box 6 fixedly installed on the bottom of the workbench 1, the collection box 6 being used to collect and place waste materials, a discharge valve 7 fixedly installed on the bottom of the collection box 6, opening the discharge valve 7 to discharge the waste materials inside the collection box 6, a placement platform 5 fixedly installed in the middle of the top of the workbench 1, the placement platform 5 having two baffles 10 inside, the two baffles 10 being symmetrically arranged, the two baffles 10 being able to rotate downwards and open synchronously; Both baffles 10 are equipped with cleaning strips 30 on their upper parts. The two cleaning strips 30 can push away the waste material on the upper part of the baffles 10. A servo motor 15 is fixedly installed on the rear side of the top of the workbench 1 via a support plate 14. The output end of the servo motor 15 is equipped with a transmission component. The transmission component is connected to the two baffles 10 and the two cleaning strips 30. When the servo motor 15 is running, it drives the two baffles 10 and the two cleaning strips 30 to run and clean the waste material through the transmission component. A slide rod 9 is fixedly installed on one end of the upper part of the shearing blade 4. A sliding sleeve 8 is fixedly installed on the rear side of the top of the support frame 2. The slide rod 9 is inserted into the sliding sleeve 8 so that the slide rod 9 can slide in the sliding sleeve 8 to limit the movement trajectory of the shearing blade 4.
[0016] In use, the operator places the SMT tape on the two baffles 10, and then starts the hydraulic cylinder 3 to drive the shearing blade 4 to move down. When the shearing blade 4 moves down, it drives the slide bar 9 to slide in the sliding sleeve 8, which increases the stability of the shearing blade 4. When the shearing blade 4 moves down, it will cut the SMT tape. Then, the operator takes away the cut SMT tape and starts the servo motor 15 at the same time. When the servo motor 15 runs, it drives the two baffles 10 to rotate downward. When the two baffles 10 rotate downward, they will dump the waste material on top into the collection box 6. At the same time, the transmission component will also drive the two cleaning strips 30 to move quickly, thereby scraping the waste material adsorbed on the upper part of the two baffles 10 into the collection box 6 for collection; so that this SMT tape cutting device can quickly and conveniently clean and collect waste material, avoid waste material scattering and jamming equipment, thereby improving production efficiency.
[0017] The transmission assembly includes a drive sprocket 16 fixedly mounted on the output end of the servo motor 15. A first gear 17 is fixedly mounted on one side of the drive sprocket 16. One side of the first gear 17 is rotatably connected to the placement platform 5 to ensure the stability of the rotation of the first gear 17. A second gear 18 is meshed with the circumferential surface of the first gear 17. A chain 21 is meshed with the surface of the drive sprocket 16. One end of the chain 21 is meshed with a driven sprocket 19. The chain 21 can transmit the power of the drive sprocket 16 to the driven sprocket 19 over a long distance. One side of the driven sprocket 19 is rotatably connected to the top of the worktable 1 through a positioning seat 20. The positioning seat 20 ensures the stability of the rotation of the driven sprocket 19. A shaft 12 is fixedly installed on one side of both the second gear 18 and the driven sprocket 19. One end of each shaft 12 extends into the interior of the placement platform 5, and one end of each shaft 12 is rotatably connected to the placement platform 5 through a bushing 13 to ensure the stability of the rotation of the two shafts 12. A rotating shaft 11 is rotatably installed on both sides of the inner wall of one side of the placement platform 5. The two ends of the two baffles 10 on the opposite side are fixedly connected to the surfaces of the two shafts 12 and the two rotating shafts 11, respectively, so that the two baffles 10 can rotate in a circle along the two shafts 12 and the two rotating shafts 11.
[0018] When the servo motor 15 is running, it drives the first gear 17 to rotate through the drive sprocket 16. When the first gear 17 rotates, it drives the second gear 18 to rotate. When the drive sprocket 16 rotates, it drives the driven sprocket 19 to rotate through the chain 21. When the driven sprocket 19 and the second gear 18 rotate, they drive the two baffles 10 to rotate downward through the two shafts 12. When the two baffles 10 rotate, they rotate along the two rotating shafts 11, which improves the stability of the rotation of the two baffles 10. When the two baffles 10 rotate downward, they dump the waste material on top of them into the collection box 6.
[0019] Both baffles 10 have lead screws 22 rotatably mounted inside them. The thread pitch of the two lead screws 22 is relatively large, which allows them to transmit power more quickly. The ends of the two lead screws 22 that are far apart from each other are fixedly mounted with first bevel gears 25 through rotating rods 23. The surfaces of the two rotating rods 23 are rotatably connected to the inside of the baffles 10 through bearings 24. The two bearings 24 ensure the stability of the ends of the two rotating rods 23 and the two lead screws 22 when rotating. One side of the surface of the first bevel gears 25 is meshed with a second bevel gear 26. Both sides of the two second bevel gears 26 are fixedly connected to the inner wall of the placement platform 5 through fixing brackets 27. The surfaces of the lead screws 22 are all threaded with threaded sleeves. The rotation of the lead screws 22 allows the threaded sleeves to move along their surfaces. The thread directions of the two lead screws 22 are opposite. The lower part of each threaded sleeve is fixedly mounted with a connecting bracket 29 via a connecting rod 28. The upper part of the two connecting brackets 29 is fixedly connected to the two ends of the two cleaning strips 30, respectively.
[0020] When the two baffles 10 rotate in opposite directions, they will drive the two first bevel gears 25 to rotate along the surfaces of the two second bevel gears 26. Through the meshing between the two, the first bevel gears 25 can rotate on their own axis. When the first bevel gears 25 rotate, they drive the lead screws 22 to rotate through the rotating rod 23. When the two lead screws 22 rotate, they drive the two lead sleeves to move rapidly in opposite directions. When the two lead sleeves move rapidly in opposite directions, they drive the two cleaning strips 30 to move rapidly through the two connecting rods 28 and the two connecting frames 29, thereby scraping the waste adsorbed on the upper part of the two baffles 10 into the inside of the collection box 6 for collection.
