Description

Technical Field

[0001] The present invention relates to the technical field of manipulators, and in particular to a manipulator based on intelligent manufacturing. Background Art

[0002] The application fields of manipulator technology are very wide, including but not limited to automobile manufacturing, electronic assembly, food processing, pharmaceutical production, etc. At present, most of the material parts loading and unloading of CNC machine tools are manually operated. However, it is relatively easy to load and unload some light materials manually, but it is very difficult to load and unload some heavy materials or longer materials. It is necessary to use tools such as cranes or balance cranes to complete the loading and unloading. For example, a cloth grabbing arm in the publication number: CN107263447A, when in use, adjusts the relative position of the two mechanical claws by adjusting the gripper through the cooperation of the slider and the slideway, or adjusts the position of one of the mechanical claws so that the center of gravity of the material falls between the two mechanical claws to ensure stability during loading. However, when loading longer materials, simply relying on the relative movement of the two mechanical claws, it is impossible to adjust the center of gravity of the material at one time, and it is necessary to clamp and adjust continuously. In addition, the adjustment of the center of gravity of the material by the mechanical claw requires the staff to operate to achieve, and it is impossible to realize automatic operation. After the material is grabbed, the position of the mechanical claw cannot be adjusted, which makes the operation process cumbersome, resulting in not only increased labor intensity, but also reduced efficiency, and unable to meet production needs.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. The present invention cooperates between the mounting bin and the four sections of the mechanical arm. After the clamping claws grab the material and move upward, when the center of gravity of the clamped material is not between the two pairs of clamping claws, the mounting bin deflects, causing the lock head to contract and release the lock on the lever, the side wall of the lever contacts and opens the paddle switch, so that the clamping claws adjust the center of gravity of the material. When the center of gravity of the clamped material is between the two pairs of clamping claws, the mounting bin drives the lever to return to its position, the paddle switch returns to its position and closes, the lock head contacts the lock port, and the lever is locked. Through the deflection of the mounting bin and the locking of the lever by the lock head, timely adjustment can be achieved when the center of gravity of the material is offset without manual intervention, and deflection of the mounting bin can be avoided when the material is transported.

[0015] 2. The present invention cooperates between the pressure plate and the support rod 1. After the installation bin is deflected, the support rod 1 deflected upward contacts the pressure plate, and the support rod 1 contracts and drives the locking sleeve to lock the rotating rod 1, so that the rotating rod 2 and the roller are locked. When the two clamping seats drive the two pairs of jaws to move in opposite directions, the upwardly deflected jaws clamp and pull the material, and the downwardly deflected jaws slide on the outside of the material. The pressure plate drives the one pair of support rods to lock the rotating rod 1 and the roller, so that after the jaws finish grabbing the material, the center of gravity of the material can be adjusted by moving the jaws.

[0016] 3. The present invention cooperates among gear six, gear three and gear two. After the clamping seat contacts the side wall of the installation bin, when the center of gravity of the material has not been adjusted, the two pairs of gear six respectively mesh with gear three and gear two, so that the rotating rod one rotates, and the rotating rod one drives the rotating rod two and the roller to rotate through the universal coupling. At this time, the material is moved by the rollers rotating inside the two pairs of jaws, so that the center of gravity of the material moves between the two pairs of jaws, which can ensure that when the jaws grab a long material, the center of gravity of the material can be adjusted at one time without repeatedly adjusting the position of the jaws, thereby reducing the operating procedures.

The fourth section of the manipulator arm 12 is rotatably installed on the side wall of the third section of the manipulator arm 113. The bottom of the fourth section of the manipulator arm 12 is rotatably installed with an installation bin 21.

The side walls of the fourth section of the manipulator arm 12 are provided with an active groove 124. The paddle switch 123 is located on both sides of the active groove 124. A lever 211 is integrally formed on the top of the installation bin 21. The lever 211 is movably installed inside the active groove 124. The side walls on both sides of the fourth section of the manipulator arm 12 are rotatably installed with a pressing plate 13. The pressing plate 13 is located above the installation bin 21. The top of the fourth section 12 of the robot arm 3 and the side wall of the fourth section 12 of the robot arm are fixedly installed with a rotating seat 131, and a pneumatic rod 132 is rotatably installed between the two rotating seats 131 on the same side.

[0032] Among them, the working principle of the installation bin 21 is as follows: after the two pairs of jaws 31 clamp the longer tubular material, the fourth section 12 of the robot arm moves upward to lift the material. When the center of the two pairs of jaws 31 and the center of the clamped material do not coincide, the installation bin 21 deflects, and the lever 211 follows the installation bin 21 to rotate inside the movable groove 124, so that the lock head 121 contracts and releases the lock on the lever 211, and the side wall of the lever 211 contacts and opens the paddle switch 123. When the center of the two pairs of jaws 31 and the center of the clamped material resume coincidence, the installation bin 21 drives the lever 211 to return to its original position, the paddle switch 123 returns to its original position and is closed, and the lock head 121 contacts the lock mouth 212, so that the lever 211 is locked to prevent the installation bin 21 from deflecting when transporting materials.

[0033] like Figure 3 , Figure 4 , Figure 6 and Figure 8As shown, a motor 213 is fixedly installed inside the mounting bin 21, and a ratchet 216 is fixedly connected to the output shaft of the motor 213.

A rack 322 is integrally formed on the side wall of the clamp seat 321, and the gear 214 and the rack 322 are meshed with each other.

[0034] Among them, the working principle of the clamp seat 321 is: when the paddle switch 123 is turned on, the motor 213 starts and rotates forward, the ratchet 216 rotates, the ratchet 216 drives the ratchet sleeve 215 and the gear 214 to rotate, the gear 214 and the two racks 322 are meshed, so that the two clamp seats 321 move in opposite directions, when the clamp seat 321 moves and contacts the inside of the installation chamber 21, the ratchet 216 rotates inside the ratchet sleeve 215, the ratchet sleeve 215 and the gear 214 stop rotating, and when the paddle switch 123 is turned off, the motor 213 is turned off.

[0035] like Figure 4 , Figure 7 and Figure 8 As shown, a motor 241 is fixedly installed inside the mounting bin 21, and a ratchet 244 is fixedly connected to the output shaft of the motor 241. A ratchet sleeve 243 is movably mounted on the outer side of the ratchet 244, and a gear 4 242 is fixedly mounted on the outer side of the ratchet sleeve 243. A gear 5 245 is fixedly mounted on the outer side of one of the slide bars 224, and the gear 5 245 is meshed with the gear 4 242. A sector gear 246 is fixedly mounted on the outer sides of the two slide bars 224, and the two sector gears 246 are meshed with each other.

[0036] Among them, the working principle of the clamp 31 is: when the motor 241 is started and rotates forward, the ratchet 244 rotates reversely, the ratchet 244 drives the ratchet sleeve 243 and the gear 4 242 to rotate, the gear 4 242 and the gear 5 245 are meshed with each other, the gear 5 245 drives one of the slide bars 224 and the fan gear 246 to rotate, the two fan gears 246 are meshed with each other, so that the two slide bars 224 drive the clamp 31 to clamp, and when the clamp 31 clamps the material, the ratchet 244 continues to rotate inside the ratchet sleeve 243, so that the clamp 31 will not loosen after the clamp 31 clamps the material.

[0037] like Figure 2 , Figure 6 and Figure 8-Figure 10As shown, the two ends of the slide bar 224 are respectively fixedly installed with a support plate 1 221 and a support plate 222, and the support plate 1 221 and the support plate 222 are respectively rotatably installed on the two sides of the installation bin 21, and the side walls of the support plate 1 221 and the support plate 222 are respectively movably installed with a gear 3 232 and a gear 2 231, and the insides of the two pairs of clamps 31 are both rotatably installed with a rotating rod 1 331, and the outer side of each rotating rod 1 331 is fixedly installed with a gear 6 332, and the two pairs of gears 6 332 are respectively meshed with the gear 3 232 and the gear 2 231, and the side wall of the support plate 222 is fixedly installed with a motor 3 234, and the output shaft of the motor 3 234 is fixedly connected to the gear 2 231 , gear three 232 is rotatably mounted on the side wall of support plate one 221, a toothed belt 233 is provided between gear three 232 and gear two 231, gear six 332 is located inside the toothed belt 233, a slide bar 1 223 is fixedly mounted between support plate one 221 and support plate two 222, each clamping jaw 31 is slidably mounted on the outside of slide bar one 223, a rotating rod two 336 is rotatably mounted inside the two pairs of clamping jaws 31, the rotating rod one 331 and the rotating rod two 336 are connected by a universal coupling 337, a roller 335 is fixedly mounted on the outside of each rotating rod two 336, the roller 335 is located inside the clamping jaw 31, and passes through the inner wall of the clamping jaw 31 to the inner side of the clamping jaw 31.

[0038] Among them, the two paddle switches 123 respectively control the forward and reverse rotation of the motor three 234, and the working principle of the roller 335 is: when the motor three 234 is started, the gear two 231 rotates, and the gear two 231 drives the gear three 232 to rotate through the toothed belt 233. When the clamp seat 321 drives the clamping jaw 31 to contact the inner wall of the installation bin 21, the two pairs of gears six 332 respectively mesh with the gear three 232 and the gear two 231, so that the rotating rod one 331 drives the rotating rod two 336 to rotate through the universal coupling 337, and the roller 335 rotates with the rotating rod two 336, so that the material inside the clamping jaw 31 moves.

[0039] like Figure 2 , Figure 7 , Fig. 9 and Fig.11 As shown, a swing rod 334 is fixedly installed on the top of the clamp 31, and a support rod 333 is slidably installed on the top of the swing rod 334. A spring 2 341 is provided between the support rod 333 and the swing rod 334. A locking sleeve 339 is slidably installed on the side wall of the support rod 333. A spring 342 is provided between the support rod 333 and the locking sleeve 339. The support rod 333 is located below the pressure plate 13.

The outer peripheral wall of the rotating rod 331 is integrally formed with a locking tooth 338, and the inner peripheral wall of the locking sleeve 339 is integrally formed with a locking tooth 343. The locking tooth 2 343 is located on the outside of the locking tooth 338.

[0040] Among them, the working principle of the rotating rod 1 331 is as follows: when the mounting bin 21 deflects, the two pairs of jaws 31 respectively follow the two sides of the mounting bin 21 to deflect upward and downward, and the pressure plate 13 contacts the support rod 1 333 that follows the upward deflection of the jaws 31, so that the support rod 1 333 slides downward along the swing rod 334, and the locking sleeve 339 follows the support rod 1 333 to slide downward along the rotating rod 1 331. At this time, the locking tooth 1 338 and the locking tooth 2 343 engage with each other, so that the roller 335 that follows the upward deflection of the jaws 31 is locked, and when the two clamping seats 321 drive the two pairs of jaws 31 to move in opposite directions, the jaws 31 that deflect upward clamp and pull the material, so that the material slides on the inner side of the jaws 31 that deflect downward.

[0041] Further references Figure 2 , Figure 7 , Fig. 9 and Fig.11 To explain, the working principle of the rotating rod 1 331 is as follows: when the clamp seat 321 drives the clamping jaws 31 to contact the inner wall of the mounting bin 21, the upwardly deflected support rod 1 333 disengages from the pressure plate 13, and the support rod 1 333 and the locking sleeve 339 return to their original positions through the spring 2 341, and the upwardly deflected rotating rod 1 331 is unlocked. At this time, the gear 6 332 drives the rotating rod 1 331 to rotate, so that the rollers 335 inside the two pairs of clamping jaws 31 rotate, and the material moves through the rollers 335, so that the centers of the two pairs of clamping jaws 31 and the centers of the clamped materials resume coincidence.

[0042] The specific working principle and use method of the present invention are explained in detail below: start the motor 241, the gear 4 242 and the gear 5 245 mesh with each other, so that the slide bar 224 rotates, and drives the two sector gears 246 to mesh with each other, and the two pairs of jaws 31 clamp the material. After the two pairs of jaws 31 clamp the material, the fourth section 12 of the mechanical arm moves upward. When the center of the two pairs of jaws 31 and the center of the clamped material do not coincide, the installation bin 21 deflects, the lever 211 contacts the paddle switch 123, the motor 1 213 and the motor 3 234 are started at the same time, and the support rod 1 333 that follows the installation bin 21 to deflect upward contacts the pressure plate 13, so that the following installation bin 21 deflects upward. 21, the upwardly deflected rotating rod 1 331 is locked, the motor 1 213 drives the gear 1 214 to rotate, the gear 1 214 and the two racks 322 are meshed with each other, so that the two clamping seats 321 drive the two pairs of jaws 31 to move in opposite directions, the upwardly deflected jaws 31 clamp and pull the material, and the downwardly deflected jaws 31 slide on the outside of the material. When the clamping seat 321 drives the jaws 31 to contact the inner wall of the installation bin 21, the two pairs of gears 6 332 are respectively meshed with the gear 3 232 and the gear 2 231, so that the rotating rod 1 331 rotates, the roller 335 rotates and transports the material, so that the center of the two pairs of jaws 31 and the center of the clamped material are restored to coincide.

[0043] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
