Description

Technical Field

[0001] This utility model belongs to the field of electronic component assembly technology, and in particular relates to a robotic arm clamping assembly and electronic component assembly equipment. Background Technology

[0002] In the assembly of electronic components, robotic arms are often used in conjunction with gripping components to grasp, move, and position the components, ensuring that they can be accurately installed in the designated positions. Such equipment is widely used in the electronics manufacturing industry. Different types of electronic components vary in size and shape, such as small surface-mount components, large housing components, and irregularly shaped components with tapered or beveled surfaces. These require a certain level of adaptability and stability from the gripping components to successfully complete the assembly operation.

[0003] Currently common robotic arm gripping components are prone to interference in some structures when gripping small electronic components, affecting normal gripping and unloading operations; when gripping large components, it is difficult to guarantee sufficient gripping range and lacks stability; when encountering conical or beveled irregularly shaped components, the grippers cannot fit the component surface and are prone to displacement. To address this, a robotic arm gripping component and electronic component assembly equipment are proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a robotic arm gripping assembly and electronic component assembly equipment, which can be adapted to components of various sizes and shapes, avoid scratches or slippage, ensure assembly stability, and solve existing technical problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A robotic arm gripping assembly and electronic component assembly equipment includes: a robotic arm, a connecting frame fixed to the drive end of the robotic arm by bolts, and a gripping mechanism provided at the bottom of the connecting frame; The clamping mechanism includes a housing, which is fixed to the bottom of the connecting frame by bolts. Two symmetrically arranged sliding plates are slidably connected between the inner walls of the two sides of the housing. The bottom of each sliding plate is integrally formed with a first gripper. A through drive shaft is rotatably connected to one side of each first gripper. A strip-shaped guide block is fixedly connected to the surface of each drive shaft. A second gripper is slidably sleeved on the circumference of each drive shaft. The second grippers are slidably connected to the guide blocks respectively. A motor is fixedly connected to one side of each sliding plate. One end of the motor output shaft is fixed to the corresponding drive shaft. The mechanism also includes a drive component for moving the second grippers. A drive assembly, housed within the housing, is used to drive the movement of the first gripper.

[0006] As a further embodiment of this utility model, the drive assembly includes a first cylinder, two rotating shafts, and two sets of teeth. The first cylinder is fixed to the top of the housing. The rotating shafts are symmetrically arranged between the two sides of the housing. Half gears are fixedly connected to the circumference of each rotating shaft. A connecting rod is rotatably connected to one side of each half gear. One end of the piston rod of the first cylinder passes through the housing and is rotatably connected to the two connecting rods. The teeth are integrally formed on the top of the slide plate and mesh with the two half gears respectively.

[0007] As a further embodiment of this utility model, the driving component includes two pull plates that rotate at one end of the second gripper, a connecting shaft is slidably connected between the tops of the pull plates, and a second cylinder is rotatably connected between the connecting shaft and the outer wall of the housing.

[0008] As a further embodiment of this utility model, protective covers are fixedly connected to both sides of the shell, and the teeth are located inside the protective covers.

[0009] As a further improvement of this utility model, silicone pads are adhered to the side of the first and second grippers near the center line of the housing.

[0010] As a further improvement of this utility model, one side of the silicone pad is integrally formed with anti-slip texture.

[0011] As a further embodiment of this utility model, a guide shaft is fixedly connected to one side of each connecting rod, and two through arc-shaped slides are opened on one side of the housing, with the guide shaft sliding along the arc-shaped slides.

[0012] Electronic component assembly equipment, including a robotic arm gripping assembly.

[0013] Working principle: During use, the robotic arm controls the displacement of the clamping mechanism. When clamping electronic components, the first cylinder is activated. The piston rod of the first cylinder drives the half gear to rotate via a connecting rod. The half gear, through its engagement with the teeth, moves the sliding plate, which in turn moves the first and second grippers, thereby clamping or releasing the electronic components. When clamping small electronic components, the motor can be activated. The motor drives the drive shaft to rotate, which in turn drives the second gripper to rotate upward and retract, preventing the second gripper from interfering with the clamping and releasing of the electronic components. When clamping large electronic components, the second cylinder is activated. The second cylinder pushes the connecting shaft to move, which in turn pushes the second gripper to slide via a pull plate, changing the distance between the first and second grippers and improving the stability of clamping large electronic components. For conical or beveled electronic components, the angle of the second gripper can be adjusted by the motor to ensure it fits snugly against the electronic component, further improving clamping stability.

[0014] The embodiments of this utility model have the following beneficial effects: In this invention, through the cooperation of a motor, drive shaft, guide block, and second gripper, as well as the arrangement of a second cylinder, pull plate, and connecting shaft, when clamping small electronic components, the motor drives the drive shaft to rotate, and the guide block drives the second gripper to retract upwards, avoiding interference between the second gripper and the small component; when clamping large electronic components, the second cylinder pushes the connecting shaft, and the pull plate drives the second gripper to slide and adjust the distance between it and the first gripper, thus adapting to the clamping needs of components of various sizes. In this invention, by setting a silicone pad on the side of the first and second grippers near the center line of the housing, and by the integrally formed anti-slip texture on the silicone pad, the silicone pad can isolate the grippers from direct contact with the surface of the components when clamping electronic components, preventing the surface of the components from being scratched; at the same time, the anti-slip texture can increase the friction between the grippers and the components, preventing the components from slipping during the clamping process and ensuring the stability of the clamping operation.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0021] In one embodiment: Please refer to Figures 1-3 As shown, this embodiment provides a robotic arm gripping assembly, including: a robotic arm 1, a connecting frame 3, a gripping mechanism 2, and a drive assembly. The robotic arm 1 adopts a multi-degree-of-freedom structure commonly used in industry, which is an existing technology. Four threaded holes are evenly opened on the end face of its drive end. The connecting frame 3 is fixed to the drive end of the robotic arm 1 by bolts engaging with the threaded holes of the drive end.

[0022] The clamping mechanism 2 is located at the bottom of the connecting frame 3 and includes a housing 4. The housing 4 is hollow inside and made of aluminum alloy. Its top is fixed to the connecting frame 3 by bolts. After installation, the housing 4 remains perpendicular to the connecting frame 3.

[0023] Two slide rails are symmetrically installed horizontally on the inner walls of both sides of the housing 4. Two sliding plates 10 are slidably connected between the two slide rails. The sliding plates 10 are rectangular metal plates, and their two side edges are adapted to the slide grooves of the slide rails. Pushing the sliding plates 10 allows them to slide horizontally within the housing 4 along the slide rails. The bottom of each sliding plate 10 has a first gripper 12 integrally formed, and the two first grippers 12 are symmetrically arranged. Each first gripper 12 has a through shaft hole on one side, and a bearing is installed in the shaft hole. The drive shaft 13 rotates through the first gripper 12 via the bearing. A guide block 16 is fixedly connected to the surface of the drive shaft 13 near the center. The guide block 16 is a long rectangular metal block, and its length direction is parallel to the axis of the drive shaft 13. A second gripper 15 is slidably fitted around the circumference of the drive shaft 13. The shape of the second gripper 15 is the same as that of the first gripper 12. A groove adapted to the guide block 16 is opened on the side near the drive shaft 13. The guide block 16 is embedded in the groove, allowing the second gripper 15 to slide along the axis of the drive shaft 13 and rotate synchronously with the drive shaft 13. A motor 14 is bolted to one outer wall of the slide plate 10. The motor 14 is a micro servo motor, and its output shaft end is fixed to one end of the corresponding drive shaft 13 through a coupling. After the motor 14 is started, the output shaft can drive the drive shaft 13 to rotate synchronously. In addition, a drive component is provided to move the second gripper 15 and adjust the position of the second gripper 15 on the drive shaft 13.

[0024] In another embodiment: refer to Appendix Figures 1-3 A robotic arm gripping assembly and electronic component assembly equipment.

[0025] The drive assembly, housed within the housing 4, drives the first gripper 12. It includes a first cylinder 5, two rotating shafts 6, and two sets of teeth 11. The first cylinder 5 is fixed to the center of the top outer wall of the housing 4 via a cylinder seat, which is bolted to the top of the housing 4. The piston rod of the first cylinder 5 faces the inner cavity of the housing, and its end extends into the housing through a pre-drilled hole in the top of the housing 4. The two rotating shafts 6 are rotatably connected to the inner walls of the front and rear sides of the housing 4 via bearings, and are symmetrically distributed on both sides of the first cylinder 5. A half-gear 7 is fixedly connected to the center of the circumference of each rotating shaft 6, with the teeth of the half-gear 7 facing the side of the housing 4 away from the centerline. A connecting rod 8 is rotatably connected to the side of each half-gear 7 away from the teeth via a pin. The other ends of both connecting rods 8 are rotatably connected to the end of the piston rod of the first cylinder 5 via pins, forming a connecting rod structure. Two sets of teeth 11 are integrally formed on the top of the two slide plates 10. The arrangement direction of the teeth 11 is consistent with the sliding direction of the slide plates 10, and the two sets of teeth 11 mesh with the gear teeth of the two half gears 7 respectively. When clamping or releasing the electronic component, the first cylinder 5 is activated. The piston rod of the first cylinder 5 extends or retracts, driving the two half gears 7 to rotate around their respective shafts 6 through the connecting rod 8. When the half gears 7 rotate, they mesh with the teeth 11, causing the two slide plates 10 to slide towards or away from each other along the slide rails on the inner wall of the housing 4. When the slide plates 10 slide, they drive the first gripper 12 at the bottom and the second gripper 15 associated with the first gripper 12 to move synchronously, thereby realizing the clamping or releasing action of the electronic component.

[0026] The driving component includes two pull plates 17. One end of each pull plate 17 is rotatably connected to the end of the corresponding second gripper 15 away from the first gripper 12. Both pull plates 17 have through-holes at their tops. A connecting shaft 18 passes through these holes, creating a sliding connection between the connecting shaft 18 and the top of the pull plate 17. One end of a second cylinder 19 is rotatably connected to the middle of the connecting shaft 18 via a pin, and the other end is rotatably connected to the outer wall of the housing 4 via a pin. The second cylinder 19 is tilted. When a larger electronic component needs to be clamped, the second cylinder 19 is activated. The piston rod of the second cylinder 19 extends or retracts, pushing the connecting shaft 18 to move. The connecting shaft 18 slides within the through-holes of the pull plate 17, causing the pull plate 17 to rotate. As the pull plate 17 rotates, it pushes the second gripper 15 to slide along the axis of the driving shaft 13, changing the distance between the first gripper 12 and the second gripper 15. This adapts to the size of larger electronic components and improves clamping stability.

[0027] Protective covers are fixed to the left and right outer walls of the housing 4 with screws. The protective covers are arc-shaped covers made of plastic, with their openings facing the inner wall of the housing 4. The lower parts of the two sets of teeth 11 and the half gear 7 are located inside the protective covers. The protective covers can prevent external dust and impurities from falling into the meshing area of ​​the teeth 11 and the half gear 7, avoiding meshing jamming that would affect the sliding of the slide plate 10. They can also prevent operators from accidentally touching the moving tooth structure.

[0028] Both the first gripper 12 and the second gripper 15 have silicone pads 20 bonded to their sides near the center line of the housing 4 using strong adhesive. This prevents the grippers from directly contacting the surface of electronic components, thus preventing scratches. One side of the silicone pad 20 also features an integrally formed diamond-shaped anti-slip texture. This texture increases the friction between the silicone pad 20 and the surface of the electronic component, preventing the component from slipping during clamping.

[0029] Guide shafts 9 are welded to the side of connecting rod 8 away from half gear 7. The guide shafts 9 are cylindrical metal rods. Two through arc-shaped slides are opened on the front outer wall of housing 4. The curvature of the arc-shaped slides is consistent with the rotation trajectory of connecting rod 8. The end of the guide shaft 9 away from connecting rod 8 passes through the arc-shaped slides and extends to the outside of housing 4. When connecting rod 8 rotates with the piston rod of first cylinder 5, guide shaft 9 can slide along the arc-shaped slides, which restricts and guides the rotation trajectory of connecting rod 8, preventing connecting rod 8 from deviating and causing half gear 7 to mesh with teeth 11 and become misaligned.
