Description

Technical Field

[0001] This invention relates to the field of robotics, specifically to a robot with a gripping and anti-dropping mechanism. Background Technology

[0002] With the rapid development of industrial automation technology, robotic gripping and handling equipment has been widely used in various fields such as 3C electronics, automobile manufacturing, and warehousing logistics. The core requirement is to ensure the stability of material gripping and the reliability of preventing material slippage while operating efficiently. Traditional gripping mechanisms often face numerous technical bottlenecks, especially for irregularly shaped parts, workpieces with offset centers of gravity, or precision parts with smooth surfaces.

[0003] In the prior art, such as the robotic gripping device disclosed in patent number CN114147754A, a secondary clamping can be performed on the basis of a primary clamping, which is beneficial for gripping some irregular goods and improves the stability of the device during gripping, making it less likely to fall. However, the anti-falling effect relies entirely on the friction of the contact surface. When gripping heavy materials or smooth metal or plastic parts, the static friction is insufficient, and the material is prone to slippage due to vibration and inertial force. In addition, the device lacks flexible adaptability and is difficult to conform to the contour of irregular materials, which can easily lead to local suspension or force concentration. This not only affects the gripping stability but may also cause damage to the surface of precision parts. At the same time, when encountering emergencies such as power failure or transmission failure, the electronic positioning is prone to failure, and the single friction force is not enough to offset the influence of external forces such as vibration and inertial force, which can easily lead to material falling accidents. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a robot with a gripping and anti-fall mechanism, comprising a main body and a base fixedly installed at the bottom of the main body, a connecting component fixedly connected to the output end of the main body, a slide rail fixedly connected to the end of the connecting component away from the main body, and sliders slidably connected to both ends of the slide rail. A clamping assembly is fixedly installed at the bottom of the slider. A fixing assembly is fixedly connected to the top of the slider. A protective assembly is fixedly connected to the bottom of the fixing assembly. A motor is fixedly connected to the side of the protective assembly closest to the slider. The clamping assembly includes a fixed plate with a square plate slidably connected to its bottom. A circular groove is provided in the middle of the bottom of the square plate, and a through hole is provided on the outer side of the square plate. The through hole is elliptical in shape, and the contour of the elliptical hole is smoother, which can reduce stress concentration at the opening of the square plate. When the robot is handling heavy objects, frequently starting and stopping, or subjected to vibration, it can avoid problems such as cracks and plastic deformation of the square plate due to excessive local stress. This structure can better withstand the alternating load brought by reciprocating motion and extend the fatigue life of the square plate and even the entire clamp.

[0005] Preferably, the protective component includes a connecting plate, with a middle block fixedly connected to the end of the connecting plate away from the fixed component. A connecting rod is threaded inside the middle block and is L-shaped. The main body drives the clamping component to approach the material, so that the clamping components on both sides of the slide rail are located on both sides of the material. Then, the slider drives the clamping component to move on the slide rail, so that the two clamping components on both sides clamp the material in the middle. At the same time, the motor is powered by an external power source and drives the connecting plate to rotate, causing the middle block to drive the connecting rod to rotate. This allows the L-shaped connecting rod to pass through the circular groove and extend to the bottom of the object. With the elastic support of the elastic inclined plate and the contact plate, the object is lifted from the bottom to prevent it from falling due to gravity. The elastic deformation of the inclined plate adapts to the shape of the bottom of the object, enhancing the contact fit and reducing the risk of slippage. A fixed block is fixedly connected to the end of the connecting rod away from the middle block, and an inclined plate is fixedly connected to the top of the fixed block. The inclined plate is elastic and the contact plate is fixedly connected to the top of the inclined plate. The connecting rod passes through the square plate through the circular groove.

[0006] Preferably, there are multiple square plates, which are evenly arranged on a fixed plate. A frame is fixedly connected to the bottom of the fixed plate, and the inner side of the frame contacts the bottom of the square plate. A groove is formed at the top of the square plate, and the groove is slidably connected to the inside of the fixed plate. The multiple square plates are slidably arranged, and with the elastic action of the elastic plate located between the square plates and the frame, the spacing can be adjusted autonomously according to the shape and size of the material. This allows the square plates to fit tightly against the material surface. Even if there are slight deviations in the material's size, the elastic plate can deform to achieve adaptive clamping. This design can accommodate both regular cubic materials and irregularly shaped materials. The clamps need to be changed for different materials. The design of the sliding square plate with the elastic plate can evenly distribute the clamping force to all contact parts of the material, avoiding excessive local pressure that could cause material damage. At the same time, the buffering effect of the elastic plate can absorb the impact force during clamping and handling, reduce rigid collisions between the square plate and the material, and extend the service life of the clamp structure. There are two buffer blocks fixedly connected to the outside of the square plate. The two buffer blocks are symmetrically arranged at both ends of the through hole. The elastic plates are symmetrically arranged inside the circular groove. An elastic plate is fixedly connected to one side of the buffer block. The end of the elastic plate away from the buffer block is fixedly connected to the inner wall of the frame.

[0007] Preferably, there are two connecting plates, which are symmetrically arranged at both ends of the middle block. There are multiple connecting rods, which are evenly arranged on the middle block. The top of the contact plate is concave and convex, which increases the microscopic contact area between the contact plate and the material surface, enabling physical interlocking. The protruding part is embedded in the tiny gaps on the material surface, improving static friction. During handling, vibration, sudden stop, or tilting operations, it can effectively prevent relative sliding between the material and the contact plate, avoiding detachment due to insufficient friction. A limit block is fixedly connected to the end of the fixed block away from the connecting rod, and a gear is fixedly connected to one side of the connecting plate.

[0008] Preferably, the fixing component includes a square plate, with the bottom center of the square plate fixedly connected to the top of the slider. Fixed seats are fixedly connected to the bottom of both ends of the square plate, and the end of the fixed seat away from the square plate is rotatably connected to one end of the connecting plate. A motor is fixedly connected to the outer side of the fixed seat, and the output end of the motor is fixedly connected to a gear. A square hole is provided in the center of the fixed seat. After the material is clamped and fixed, the elastic force of the compression spring causes the sliding block to slide along the fixed rod inside the square hole, so that the protrusion is located inside the gear tooth groove. The support state is locked through mechanical meshing, preventing the material from falling off due to mechanism failure. It also prevents the pallet from accidentally overturning during handling due to vibration, inertia, or external force collisions, always maintaining bottom support for the material and reducing the risk of the material slipping off the bottom. A fixed rod is fixedly connected to the center of the square hole, and a compression spring is sleeved on the outer side of the fixed rod. A sliding block is slidably connected to the inner wall of the square hole, and the fixed rod and sliding block are slidably connected. The two ends of the compression spring are fixedly connected to the inner wall of the square hole and the sliding block, respectively. A protrusion is fixedly connected to the side of the sliding block closest to the gear.

[0009] Preferably, the connecting assembly includes a positioning plate, which is fixedly connected to the top center of the slide rail. A circular seat is fixedly connected to the top center of the positioning plate, and an arc block is fixedly connected to the top of the circular seat. The arc block is semi-circular, and there are two arc blocks symmetrically arranged on the circular seat. A magnetic block is slidably connected inside the arc block, and the two magnetic blocks have the same magnetism. The cylinder is installed on the outside of the arc block, so that the middle rod is located inside the groove. At the same time, the magnetic block contacts the inner wall of the cylinder and generates pressure, causing the magnetic block to move towards the middle rod inside the arc block, so that the arc at the end of the magnetic block... The plate is located inside the annular groove, allowing the slide rail to be installed at the output end of the main body via a connecting assembly. The connecting assembly secures the clamping component to the main body through a snap-fit ​​mechanism, enabling quick replacement of suitable clamping parts and reducing downtime. Furthermore, the arc block, intermediate rod, and slot ensure automatic alignment during installation, guaranteeing coaxiality or parallelism between the clamping part and the main body, preventing material misalignment or detachment due to installation deviations. Simultaneously, the mechanical engagement structure after snap-fit ​​counteracts vibration and impact during handling, maintaining connection rigidity and improving gripping accuracy. There are two magnetic blocks, which penetrate the arc block. An arc plate is fixedly connected to one end of the block, located at the gap between two arc blocks. A cylinder is fitted around the outer side of the arc blocks, and a central rod is fixedly connected to the middle of the cylinder's interior. A ring groove is provided on the outer side of the central rod near the magnetic block, and a return spring is fitted around the outer side of the central rod. The return spring and the ring form a buffer structure. During installation, clamping, or handling vibrations, the return spring absorbs the impact force, preventing rigid collisions between the arc blocks, magnetic blocks, and the inner wall of the cylinder, reducing wear. Simultaneously, the elastic preload of the return spring compensates for minor dimensional deviations during processing or installation, ensuring the clamping structure remains tight. The tight meshing prevents wobbling caused by gaps, reduces component fatigue, and extends the overall service life of the connecting assembly. A ring is slidably connected to the outer side of the intermediate rod, and the outer side of the ring is slidably connected to the inner wall of the cylinder. The two ends of the return spring are fixedly connected to the inner wall of the cylinder and the ring, respectively. A limit groove is opened on the inner wall of the cylinder near the magnetic block, and a slot is opened on the opposite side of the arc block. The intermediate rod is located inside the slot. An extension plate is fixedly connected to the outer side of the intermediate rod. There are two extension plates, which are symmetrically arranged with the intermediate rod as the center. The extension plates are located at the interval between the two arc blocks.

[0010] This invention provides a robot with a gripping and anti-drop mechanism. It has the following beneficial effects: (i) The robot with the gripping and anti-fall mechanism extends to the bottom of the object through the L-shaped connecting rod through the circular groove. With the elastic support of the elastic inclined plate and the contact plate, it not only lifts the object from the bottom to prevent it from falling due to gravity, but also adapts to the shape of the bottom of the object through the elastic deformation of the inclined plate, thereby enhancing the contact fit and reducing the risk of slippage.

[0011] (ii) The robot with the gripping and anti-dropping mechanism uses multiple square plates that are slidably set up. With the elastic action of the elastic plate located between the square plates and the frame, the spacing can be adjusted autonomously according to the shape and size of the material. This allows the square plates to fit tightly against the surface of the material. Even if there are slight deviations in the size of the material, the elastic plate can deform to achieve adaptive clamping. It can fit neat square materials as well as irregularly shaped materials.

[0012] (III) The robot with the gripping and anti-dropping mechanism has an elliptical through hole. The contour of the elliptical hole is smoother, which can reduce the stress concentration at the opening of the square plate. When the robot is carrying heavy objects, frequently starting and stopping, or subjected to vibration, it can avoid problems such as cracks and plastic deformation of the square plate due to excessive local stress. This structure can better withstand the alternating load brought by reciprocating motion and extend the fatigue life of the square plate and even the entire fixture.

[0013] (iv) The robot with the gripping and anti-dropping mechanism locks the support state through mechanical engagement, preventing the material from falling off due to mechanism failure. It can also prevent the pallet from accidentally flipping over due to vibration, inertia or external force collision during the handling process, and always maintains bottom support for the material, reducing the risk of the material slipping off the bottom.

[0016] 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.

[0017] First embodiment, such as Figures 1 to 8 As shown, the present invention provides a technical solution: a robot with a gripping and anti-dropping mechanism, including a main body 2 and a base 1 fixedly installed at the bottom of the main body 2. A connecting component 3 is fixedly connected to the output end of the main body 2. A slide rail 4 is fixedly connected to the end of the connecting component 3 away from the main body 2. Sliding sliders 5 are slidably connected to both ends of the slide rail 4. The clamping component 6 is fixedly installed at the bottom of the slider 5. The top of the slider 5 is fixedly connected to the fixing component 7. The bottom of the fixing component 7 is fixedly connected to the protective component 9. The side of the protective component 9 closest to the slider 5 is fixedly connected to the motor 8. The clamping assembly 6 includes a fixed plate 61, with a square plate 62 slidably connected to the bottom of the fixed plate 61. A circular groove 63 is provided in the middle of the bottom of the square plate 62, and a through hole 66 is provided on the outer side of the square plate 62. The through hole 66 is elliptical in shape, and the contour transition of the elliptical hole is smoother, which can reduce the stress concentration phenomenon at the opening of the square plate 62. When the robot is carrying heavy objects, frequently starting and stopping, or subjected to vibration, it can avoid problems such as cracks and plastic deformation of the square plate due to excessive local stress. This structure can better withstand the alternating load brought by reciprocating motion and extend the fatigue life of the square plate 62 and even the entire clamp.

[0018] The protective component 9 includes a connecting plate 91. A middle block 94 is fixedly connected to the end of the connecting plate 91 furthest from the fixing component 7. A connecting rod 93, L-shaped, is threaded into the middle block 94. The main body 2 moves the clamping component 6 closer to the material, positioning the clamping components 6 on both sides of the slide rail 4 on either side of the material. Then, the slider 5 moves the clamping components 6 along the slide rail 4, thus clamping the material in the middle with the two clamping components 6 on both sides. Simultaneously, the motor 8, powered by an external power source, rotates the connecting plate 91, causing the middle block 94 to rotate and drive the connecting rod 93 to rotate. This allows the L-shaped connecting rod 93 to extend through the circular groove 63 to the bottom of the object. Combined with the elastic support of the elastic inclined plate 98 and the contact plate 96, the object is lifted from the bottom to prevent it from falling due to gravity. The elastic deformation of the inclined plate 98 adapts to the shape of the bottom of the object, enhancing the contact fit and reducing the risk of slippage. The end of the connecting rod 93 away from the middle block 94 is fixedly connected to the fixing block 95. The top of the fixing block 95 is fixedly connected to the inclined plate 98, which is elastically designed. The top of the inclined plate 98 is fixedly connected to the contact plate 96. The connecting rod 93 passes through the square plate 62 through the circular groove 63.

[0019] Multiple square plates 62 are evenly arranged on a fixed plate 61. A frame 67 is fixedly connected to the bottom of the fixed plate 61, and the inner side of the frame 67 contacts the bottom of the square plates 62. A sliding groove 69 is provided on the top of each square plate 62, and the groove 69 is slidably connected to the interior of the fixed plate 61. The multiple square plates 62 are slidably arranged, and with the elastic action of the elastic plate 68 located between the square plates 62 and the frame 67, the spacing can be adjusted autonomously according to the shape and size of the material. This allows the square plates 62 to fit tightly against the material surface. Even if there are slight deviations in the material's size, the elastic plate 68 can deform to achieve adaptive clamping. This allows for the fitting of both regular cubic materials and irregularly shaped materials. The clamps need to be changed for different materials. The design of sliding square plate 62 with elastic plate 68 can evenly distribute the clamping force to each contact part of the material, avoiding excessive local pressure that could cause material damage. At the same time, the buffering effect of elastic plate 68 can absorb the impact force during clamping and handling, reduce rigid collisions between the square plate and the material, and extend the service life of the clamp structure. Buffer blocks 65 are fixedly connected to the outer side of square plate 62. There are two buffer blocks 65, which are symmetrically arranged at both ends of through hole 66. Elastic plates 64 are symmetrically arranged inside circular groove 63. Elastic plate 68 is fixedly connected to one side of buffer block 65. The end of elastic plate 68 away from buffer block 65 is fixedly connected to the inner wall of frame 67.

[0020] There are two connecting plates 91, which are symmetrically arranged at both ends of the middle block 94. There are multiple connecting rods 93, which are evenly arranged on the middle block 94. The top of the contact plate 96 is concave and convex. The concave and convex structure can increase the microscopic contact area between the contact plate 96 and the material surface, and can form a physical interlocking state. The protruding part is embedded in the tiny gaps on the material surface, which can improve the static friction. During the handling process, when encountering vibration, sudden stop or tilting operation, it can also effectively prevent the material from sliding relative to the contact plate 96, and avoid falling off due to insufficient friction. The end of the fixing block 95 away from the connecting rod 93 is fixedly connected to the limit block 97. A gear 92 is fixedly connected to one side of the connecting plate 91.

[0021] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 9 As shown, the fixing assembly 7 includes a square plate 71, with the bottom center of the square plate 71 fixedly connected to the top of the slider 5. Fixing seats 72 are fixedly connected to the bottom of both ends of the square plate 71. The end of the fixing seat 72 away from the square plate 71 is rotatably connected to one end of the connecting plate 91. The motor 8 is fixedly connected to the outer side of the fixing seat 72, and the output end of the motor 8 is fixedly connected to the gear 92. A square hole 73 is provided in the middle of the fixing seat 72. After the material is clamped and fixed, the spring force of the compression spring 75 causes the sliding block 76 to slide along the fixing rod 74 inside the square hole 73, so that the protrusion 77 is located inside the tooth groove of the gear 92. The mechanical engagement method locks the support state, preventing materials from falling off due to mechanism failure, and also preventing the pallet from accidentally overturning during transportation due to vibration, inertia or external force collision. It always maintains bottom support for the materials, reducing the risk of materials slipping off the bottom. A fixing rod 74 is fixedly connected to the middle of the inside of the square hole 73. A compression spring 75 is sleeved on the outside of the fixing rod 74. A sliding block 76 is slidably connected to the inner wall of the square hole 73. The fixing rod 74 and the sliding block 76 are slidably connected. The two ends of the compression spring 75 are fixedly connected to the inner wall of the square hole 73 and the sliding block 76, respectively. A protrusion 77 is fixedly connected to the side of the sliding block 76 near the gear 92.

[0022] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 10 to 12As shown, the connecting assembly 3 includes a positioning plate 31, which is fixedly connected to the top center of the slide rail 4. A circular seat 32 is fixedly connected to the top center of the positioning plate 31, and an arc block 33 is fixedly connected to the top of the circular seat 32. The arc block 33 is semi-circular, and there are two arc blocks 33 symmetrically arranged on the circular seat 32. A magnetic block 34 is slidably connected inside the arc block 33, and the two magnetic blocks 34 have the same magnetism. The cylinder 35 is installed on the outside of the arc block 33, so that the intermediate rod 38 is located inside the slot 310. At the same time, the magnetic block 34 contacts and is squeezed against the inner wall of the cylinder 35, causing the magnetic block 34 to move towards the intermediate rod 38 inside the arc block 33. The arc plate 39 at the end of the magnetic block 34 is located inside the annular groove, so the slide rail 4 is installed at the output end of the main body 2 through the connecting assembly 3. The connecting assembly 3 fixes the clamping assembly 6 to the main body 2 by snap-fit, which allows for quick replacement of the appropriate clamping parts and reduces downtime. Furthermore, through the arc block 33, the intermediate rod 38, and the slot 310, the installation can be automatically aligned to ensure the coaxiality or parallelism of the clamping parts and the main body 2, avoiding material grabbing deviation or falling off due to installation misalignment. At the same time, the mechanical meshing structure after snap-fit ​​can offset the vibration and impact force during the handling process, maintain connection rigidity, and improve gripping accuracy. There are two magnetic blocks 34, which pass through the arc block 33, and one end of the arc block 33 is fixedly connected. An arc plate 39 is located at the interval between two arc blocks 33. A cylinder 35 is sleeved on the outer side of the arc blocks 33. A middle rod 38 is fixedly connected to the middle of the inner part of the cylinder 35. The middle rod 38 has an annular groove on the outer side near the magnetic block 34. A return spring 36 is sleeved on the outer side of the middle rod 38. The return spring 36 on the outer side of the middle rod 38 and the annular ring 37 form a buffer structure. During installation, clamping, or handling vibration, the return spring 36 can absorb the impact force, avoid rigid collision between the arc blocks 33, the magnetic block 34 and the inner wall of the cylinder 35, and reduce wear. At the same time, the elastic preload of the return spring 36 can compensate for minor dimensional deviations during processing or installation, ensuring that the clamping structure is always tightly engaged and avoiding gaps. While the shaking is reduced, the fatigue wear of the components is reduced and the overall service life of the connecting components is extended. A ring 37 is slidably connected to the outer side of the intermediate rod 38. The outer side of the ring 37 is slidably connected to the inner wall of the cylinder 35. The two ends of the return spring 36 are fixedly connected to the inner wall of the cylinder 35 and the ring 37, respectively. A limit groove 311 is opened on the inner wall of the cylinder 35 near the magnetic block 34. A slot 310 is opened on the opposite side of the arc block 33. The intermediate rod 38 is located inside the slot 310. An extension plate 312 is fixedly connected to the outer side of the intermediate rod 38. There are two extension plates 312. The two extension plates 312 are symmetrically arranged with the intermediate rod 38 as the center. The extension plates 312 are located at the interval between the two arc blocks 33.

[0023] In use, the main body 2 moves the clamping assembly 6 closer to the material, so that the clamping assemblies 6 on both sides of the slide rail 4 are located on both sides of the material. Then, the slider 5 moves the clamping assembly 6 on the slide rail 4, so that the two clamping assemblies 6 on both sides clamp the material in the middle. At the same time, the motor 8 is powered by an external power source and the motor 8 drives the electric connecting plate 91 to rotate, so that the middle block 94 drives the connecting rod 93 to rotate, so that the L-shaped connecting rod 93 passes through the circular groove 63 and extends to the bottom of the object. With the elastic support of the elastic inclined plate 98 and the contact plate 96, the object is lifted from the bottom.

[0024] After the material is clamped and fixed, the elastic force of the compression spring 75 is used to make the sliding block 76 slide along the fixed rod 74 inside the square hole 73, so that the protrusion 77 is located inside the tooth groove of the gear 92, and the support state is locked by mechanical meshing to prevent the material from falling off due to mechanism failure.
