Technical Field
[0001] This invention relates to the field of mechanical design and manufacturing technology, specifically to a robot loading and clamping device. Background Technology
[0002] Robotic feeding and gripping devices are mechanical components used in industrial automation for gripping, positioning, and transferring materials. They typically consist of grippers, pneumatic or electric drive mechanisms, and sensors, and are integrated into the robot's end effector. Their core function is to replace manual labor in automatically feeding, sorting, and assembling raw materials, semi-finished products, or finished products on the production line through precise and reliable gripping actions, significantly improving efficiency, consistency, and safety. They are widely used in automotive manufacturing, 3C electronics, food packaging, and other fields, and are one of the key modules of flexible intelligent production lines.
[0003] The operation of a robotic material handling device typically consists of four stages: positioning, gripping, conveying, and releasing. A vision system or sensors identify the position and orientation of the target material. The robot adjusts the gripping device to precise alignment. Subsequently, the drive mechanism controls the grippers to close, ensuring stable gripping without damaging the material through force feedback or an adaptive structure. The robotic arm drives the gripping device to rapidly convey the material along a predetermined path to the processing station or the next process step. Finally, the grippers release the material and reset according to instructions, completing a single loading cycle. The entire process is synchronized with the production line cycle time, enabling high-speed, high-repeatability automated operation.
[0004] Material slippage or displacement during handling can occur due to factors such as insufficient clamping force, smooth material surface, irregular shape, inertial vibration during high-speed robot movement, or external vibration interference. Material slippage can lead to processing interruptions, equipment damage, or product scrapping, especially causing significant economic losses for high-value precision parts. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] refer to Figures 1 to 9 A preferred embodiment of the present invention, a robotic feeding and clamping device, will be described in detail below, includes a robotic arm 1, one end of which is fixedly connected to a fixed outer frame 2. The fixed outer frame 2 has a slidingly connected clamping frame 27 for clamping materials. The fixed outer frame 2 has an adjusting circular plate 22 inside for driving the clamping frame 27 to tighten towards the center. The fixed outer frame 2 also has a power circular plate 31 inside for adjusting the material clamping state. The clamping frame 27 has a sealing block 61 inside to prevent the clamped material from detaching. The clamping frame 27 has a pressure groove 64 inside for adjusting the extension state of the sealing block 61. The clamping frame 27 also has a pressing block 79 inside for secondary clamping of the material, thereby improving the stability of material transport.
[0019] The fixed outer frame 2 has a first groove 21 inside. An adjusting circular plate 22 is rotatably connected inside the first groove 21. The surface of the adjusting circular plate 22 has four second grooves 23 arranged in a ring. The surface of the fixed outer frame 2 has four guide grooves 25 arranged in a ring. All four guide grooves 25 are connected to the first groove 21. The interior of each of the four second grooves 23 is slidably connected to a sliding circular shaft 24. The interior of each of the four guide grooves 25 is slidably connected to a guide block 26 via a slider. The guide block 26 is fixedly connected to the sliding circular shaft 24. The pressing frame 27 is fixedly connected to one side surface of the guide block 26.
[0020] The fixed outer frame 2 has a third groove 3 inside, and a shrinkage groove is formed between the third groove 3 and the first groove 21. The power circular plate 31 is rotatably connected to the inside of the third groove 3. The robotic arm 1 is equipped with an electric telescopic rod, which is fixedly connected to the power circular plate 31. A connecting frame 33 is fixedly connected to one side of the adjusting circular plate 22. A pulling rod 32 is slidably connected inside the connecting frame 33. A first spring 34 is fixedly connected between the pulling rod 32 and the power circular plate 31. The inner wall of the connecting frame 33 has an inclined groove 35. A pulling shaft 36 is fixedly connected to the surface of the pulling rod 32 and extends into the inside of the inclined groove 35. When the robot grips and moves the material to feed it... The electric telescopic rod drives the power plate 31 to slide away from the material. The power plate 31 drives the pull rod 32 to slide synchronously through the first spring 34. In turn, the pull rod 32 drives the pull shaft 36 to move. The pull shaft 36 slides along the inclined groove 35. At the same time, the pull shaft 36 gives a thrust to the inner wall of the inclined groove 35, causing the connecting frame 33 to rotate. This causes the adjusting plate 22 to rotate along the first groove 21. When the adjusting plate 22 rotates, the sliding shaft 24 slides along the second groove 23. At the same time, the second groove 23 gives a thrust to the sliding shaft 24. This push causes the clamping frame 27 to move closer to the center of the adjusting plate 22 through the guide block 26, thereby clamping the material.
[0021] The clamping frame 27 has a fourth groove 4 inside, and a clamping block 41 is slidably connected inside the fourth groove 4. The surface of the clamping block 41 near the material is rough. A fifth groove 42 is opened on one inner wall of the fourth groove 4. The fifth groove 42 extends through the guide block 26 and the sliding round shaft 24 into the interior of the third groove 3. A guide rail 43 is fixedly connected to the surface of the power round plate 31. A sliding rod 44 is slidably connected inside the fifth groove 42. One end of the sliding rod 44 is engaged with the guide rail 43, and the sliding rod 44 and the guide rail are also engaged. The sliding connection of the track 43 is such that when the four clamping frames 27 drive the clamping blocks 41 to clamp the material, the electric telescopic rod drives the power plate 31 to slide continuously. Since the adjusting plate 22 cannot continue to rotate under the clamping action of the clamping frames 27, the pulling rod 32 also cannot slide under the restriction of the connecting frame 33. The first spring 34 is continuously stretched, and the power plate 31 continues to slide. The power plate 31 pulls the sliding rod 44 to slide synchronously through the guide rail 43 on the surface, thereby driving the clamping block 41 to slide synchronously.
[0022] The clamping block 41 has a sixth groove 5 inside, and an extension block 51 is slidably connected inside the sixth groove 5. Seventh grooves 52 are formed on both sides of the inner wall of the sixth groove 5. A second spring 53 is fixedly connected inside the seventh groove 52. Side blocks are fixedly connected to both sides of the extension block 51, and the two side blocks on both sides of the extension block 51 extend into the two seventh grooves 52 respectively. An eighth groove 55 is formed on the inner wall of the fourth groove 4. A pressure block 57 is slidably connected inside the eighth groove 55. A second spring 53 is fixedly connected inside the eighth groove 55. A third spring 56 is connected, and the spring constant of the third spring 56 is greater than that of the second spring 53. An extension rod 54 is fixedly connected to one side of the side block. The extension rod 54 extends into the interior of the eighth slot 55. The eighth slot 55 is located on the sliding path of the extension rod 54. During the process of the pressing block 41 sliding towards the power circular plate 31 and driving the extension block 51 to slide synchronously, the extension rod 54 on the surface of the extension block 51 contacts the pressure block 57. The extension block 51 cannot slide under the restriction given by the third spring 56.
[0023] The extension block 51 has a groove 6 extending through it. The sealing block 61 is slidably connected to the inside of the groove 6. The inner wall of the groove 6 has a sliding groove. A contact pressure plate 63 is slidably connected to the inside of the sliding groove in the groove 6. A spring 62 is fixedly connected to the inside of the sliding groove in the groove 6. The spring 62 is fixedly connected to the contact pressure plate 63. The inner wall of the groove 4 has a pressure groove 64. One side of the pressure groove 64 has an inclined surface. The sealing block 61 extends into the pressure groove 64. The pressing block 41 slides continuously under the action of the sliding rod 44, thereby creating a relative displacement with the extension block 51 in the restricted position, until the extension block 51 moves the sealing block 61. Part of the material slides out of the interior of slot 5, and at this time, the sealing block 61 is located on the side of the pressing block 41 away from the sliding rod 44. As the pressing block 41 continues to slide, it will drive the extension block 51 and the sealing block 61 to move synchronously. At this time, the extension rod 54 drives the pressure block 57 to compress the third spring 56. The sealing block 61 slides along the pressure groove 64 until the sealing block 61 contacts the inclined surface of the pressure groove 64. At this time, the sealing block 61 is squeezed and contracted into the interior of the extension block 51, and one end of the sealing block 61 extends out of the interior of the extension block 51, forming a baffle under the material to prevent the material from falling off due to its smooth surface and external vibration, thus achieving the purpose of preventing the clamped material from falling off.
[0024] The clamping frame 27 has a groove 7 (number 10) inside. A connecting groove is formed between groove 7 (number 10) and groove 42 (number 5). An extension rod 72 is slidably connected inside groove 7 (number 10). A spring 71 (number 5) is fixedly connected to the inner wall of groove 7 (number 10). Spring 71 is fixedly connected to the extension rod 72. A tightening groove 73 is formed at one end of the extension rod 72. A sliding block 75 is slidably connected inside the tightening groove 73. A spring 74 (number 6) is fixedly connected to the inner wall of the tightening groove 73. The sliding block 75 is fixedly connected to spring 74 (number 6). A fixing block 76 is fixedly connected to one side of the sliding rod 44. Both the fixed abutment 76 and the sliding abutment 75 extend into the interior of the connecting groove. A contact abutment 77 is fixedly connected to the inner wall of the connecting groove between groove 7 and groove 42. The thickness of both the contact abutment 77 and the fixed abutment 76 is half the thickness of the sliding abutment 75. The contact abutment 77 is not located on the sliding path of the fixed abutment 76. An inclined surface is provided on the side of the sliding abutment 75 and the contact abutment 77 that are close to each other. The inclined surface of the sliding abutment 75 fits against the inclined surface of the contact abutment 77. A pressing groove is provided on the surface of the pressing block 41. A pressing surface block 7 is slidably connected inside the pressing groove of the pressing block 41. 9. A No. 7 spring 78 is fixedly connected to the inner wall of the pressing groove of the pressing block 41. The accuracy coefficient of the No. 5 spring 71 is greater than the stiffness coefficient of the No. 7 spring 78. The No. 7 spring 78 is fixedly connected to the pressing block 79. The extension rod 72 extends into the interior of the pressing groove. During the sliding process of the pressing block 41 driven by the sliding rod 44, a thrust is given to the sliding block 75 through the fixed block 76, which drives the extension rod 72 to slide synchronously with the sliding rod 44. When the pressing block 41 is located at one end of the No. 4 groove 4, the sealing block 61 is pushed along the lower surface of the pressing block 41 by the inclined surface of the pressure groove 64. When the sliding block 75 slides towards the material to form a baffle, it contacts the inclined surface of the contact block 77 and retracts into the tightening groove 73 under the push of the inclined surface of the contact block 77. At the same time, the extension pressure rod 72 loses the restriction of the fixed block 76 and slides away from the sliding rod 44 under the action of the No. 5 spring 71, and then extends into the interior of the pressing groove, pushing the pressing block 79 to slide towards the material. Then, in conjunction with the sealing block 61 at the bottom of the material, the material is clamped, the center of gravity of the material is locked, and the inertial shaking of the material during the feeding process is resisted, thus improving the safety of the material feeding process.
[0025] The following is the complete working process and working principle of the above embodiment: When the robot clamps and drives the material to be fed, the electric telescopic rod drives the power plate 31 to slide away from the material. The power plate 31 drives the pull rod 32 to slide synchronously through the first spring 34, and then drives the pull shaft 36 to move through the pull rod 32. The pull shaft 36 slides along the inclined groove 35. At the same time, the pull shaft 36 gives a push force to the inner wall of the inclined groove 35, causing the connecting frame 33 to rotate, driving the adjusting plate 22 to rotate along the first groove 21. When the adjusting plate 22 rotates, the sliding shaft 24 slides along the second groove 23. At the same time, the second groove 23 gives a push force to the sliding shaft 24, and then drives the clamping frame 27 to move closer to the center position of the adjusting plate 22 through the guide block 26, thereby clamping the material. After the four clamping frames 27 clamp the material with the clamping block 41, the electric telescopic rod drives the power plate 31 to slide continuously. Since the adjusting plate 22 cannot continue to rotate under the clamping action of the clamping frame 27, the pulling rod 32 also cannot slide under the restriction of the connecting frame 33. The first spring 34 is continuously stretched, and the power plate 31 continues to slide. The power plate 31 pulls the sliding rod 44 to slide synchronously through the guide rail 43 on its surface, which in turn drives the clamping block 41 to slide synchronously. During the process of the clamping block 41 sliding towards the power plate 31 and driving the extension block 51 to slide synchronously, the extension rod 54 on the surface of the extension block 51 contacts the pressure block 57. The extension block 51 cannot slide under the restriction given by the third spring 56. The clamping block 41 slides continuously under the action of the sliding rod 44, thereby creating a relative displacement with the extension block 51 in the restricted position, until the extension block 51 drives part of the sealing block 61 to slide out of the interior of the sixth groove 5. At this time, the sealing block 61 is located on the side of the clamping block 41 away from the sliding rod 44. As the clamping block 41 continues to slide, it will drive the extension block 51 and the sealing block 61 to move synchronously. At this time, the extension rod 54 drives the pressure block 57 to compress the third spring 56. The sealing block 61 slides along the pressure groove 64 until the sealing block 61 contacts the inclined surface of the pressure groove 64. At this time, the sealing block 61 is squeezed and contracted into the interior of the extension block 51, and one end of the sealing block 61 extends out of the interior of the extension block 51, forming a baffle under the material to prevent the material from falling off due to its smooth surface and external vibration, thus achieving the purpose of preventing the clamped material from falling off.
[0026] During the sliding process of the sliding rod 44 driving the pressing block 41 to slide, the fixed abutment 76 provides a pushing force to the sliding abutment 75, causing the extension pressure rod 72 to slide synchronously with the sliding rod 44. When the pressing block 41 is located at one end of the fourth groove 4, the sealing block 61 slides along the lower surface of the pressing block 41 towards the material direction under the push of the inclined surface of the pressure groove 64 to form a baffle. At this time, the sliding abutment 75 contacts the inclined surface of the contact abutment 77 and retracts into the interior of the tightening groove 73 under the push of the inclined surface of the contact abutment 77. The extension pressure rod 72 loses the restriction of the fixed abutment 76 and slides away from the sliding rod 44 under the action of the fifth spring 71, thus extending into the interior of the pressing groove and pushing the pressing block 79 to slide towards the material direction. This, in turn, cooperates with the sealing block 61 at the bottom of the material to clamp the material, lock the center of gravity of the material, resist the inertial shaking of the material during the feeding process, and improve the safety of the material feeding process.
