Description

Technical Field

[0001] This utility model belongs to the field of robotic arms, and specifically relates to a novel robotic arm. Background Technology

[0002] In modern industrial automated production, robotic arms, as core execution devices, are widely used in material handling, assembly, and processing. Their functionality heavily relies on the adaptability of end effectors. However, existing robotic arm gripper systems suffer from significant technical bottlenecks, making it difficult to meet diverse production needs.

[0003] Currently, most mainstream industrial robotic arms adopt a single fixture fixed installation mode, meaning that a single robotic arm can usually only match one type or specification of fixture. When the production line needs to switch product types or handle workpieces of different sizes and shapes, the machine needs to be stopped and the entire set of fixtures needs to be replaced manually, or even the end structure of the robotic arm needs to be adjusted. This process can take tens of minutes to several hours.

[0004] In addition, the existing fixture assembly and disassembly process is complicated and lacks a quick positioning mechanism. Traditional fixtures are mostly fixed to the end of the robotic arm by bolt fastening or flange connection. Manual operation requires the use of special tools to complete multiple processes such as disassembly, alignment, installation and precision calibration. The cost of each changeover is high, and problems such as unstable workpiece clamping and positioning deviation are easily caused by improper installation, which affects the consistency of product quality. Although some equipment has tried to introduce quick-change structure, there are still defects such as poor interface compatibility, insufficient load capacity and low degree of automation, which cannot achieve "plug and play" of fixture types.

[0005] From the perspective of technological evolution, as the demand for flexible production in intelligent manufacturing increases, robotic arms need to have the ability to quickly switch between multiple grippers and adapt to different workpieces. The existing single gripper mode and inefficient changeover process have poor overall application adaptability, so it is necessary to improve its design. Utility Model Content

[0006] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a new type of robotic arm to solve the problem of adaptability and performance of robotic arms during the application of existing technologies.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A novel robotic arm includes a telescopic cylinder, a rotating assembly fixedly mounted on the bottom of the telescopic cylinder, and a mounting mechanism fixedly mounted on the bottom of the rotating assembly in a ring at equal intervals. A pneumatic industrial gripper, a pointed tool, and a pneumatic industrial suction cup are respectively mounted on the bottom of the rotating assembly through the mounting mechanism.

[0009] The rotating assembly includes a base plate, which is fixedly installed at the bottom output end of the telescopic cylinder. A drive motor is fixedly installed at the bottom of the base plate, and a fixed plate is fixedly installed at the output end of the drive motor. A semi-circular block is fixedly installed at the bottom of the fixed plate. The mounting mechanism is arranged in a ring at equal intervals and fixedly installed on the outer surface of the semi-circular block away from the drive motor.

[0010] Furthermore, a cover shell is fixedly installed on the bottom of the base plate, and the cover shell covers the outside of the drive motor.

[0011] Furthermore, the mounting mechanism includes a fixed base, which is fixedly installed on the outer surface of the semicircular block away from the drive motor in a ring-shaped arrangement at equal intervals. A sleeve frame is fixedly installed on the outer side of the fixed base, and a mounting block is inserted inside the sleeve frame. A connecting plate is fixedly installed on the outer side of the mounting block. The pneumatic industrial gripper, the pointed tool, and the pneumatic industrial suction cup are respectively fixedly connected to the outer side of the connecting plate at the corresponding positions at their respective ends near the semicircular block. A limit component is fixedly installed on the outer side of the fixed base, and the limiting end of the limit component is engaged with the mounting block.

[0012] Furthermore, the limiting component includes a side frame, which is fixedly installed on the outside of the fixed base. A limiting spring is fixedly connected inside the side frame. A movable block is fixedly connected to the end of the limiting spring. A limiting arm is fixedly connected to the outside of the movable block. A limiting pin is fixedly connected to the outside of the limiting arm. A limiting hole is opened in the middle of the side of the mounting block near the movable block. The end of the limiting pin is inserted into the limiting hole.

[0013] Furthermore, a connecting shaft is fixedly connected to the outer side of the movable block, and the end of the connecting shaft passes through the side frame.

[0014] Furthermore, an adjusting arm is fixedly connected to the end of the connecting shaft through the side frame, and an adjusting handrail is fixedly connected to the outside of the adjusting arm.

[0015] Furthermore, a mounting plate is fixedly installed on the top of the telescopic cylinder, and mounting holes are arranged in a ring at equal intervals on the outer side of the mounting plate, and the mounting holes are countersunk holes.

[0016] In summary, the present invention has the following main advantages:

[0017] First, this robotic arm utilizes a rotating assembly structure, with a drive motor rotating a semi-circular block to synchronize the rotation of the ring-shaped mounting mechanism. This allows for the rapid transfer of target fixtures such as pneumatic industrial grippers and pneumatic industrial suction cups to the work area for alignment, achieving automated switching. This design breaks the limitations of traditional single fixtures and can be flexibly adjusted as needed. For example, grippers can be used to handle metal parts, while suction cups can be used to move smooth, panel-shaped workpieces, reducing production line downtime and improving the adaptability and flexibility of multi-variety production scenarios.

[0018] Secondly, the installation mechanism of this device adopts a plug-in design of the sleeve frame and the installation block, combined with the elastic snap-fit ​​function of the limit component to realize quick installation and quick removal of the clamp. During installation, the installation block is inserted, and after the limit spring is compressed, the locking pin is embedded in the limit hole to lock. During disassembly, the adjustment handle is pulled to disengage the locking pin from the limit hole. This structure does not require tools and can be operated quickly by a single person, which greatly improves efficiency compared with the traditional method. The limit spring ensures the stability of the clamp, and the modular design supports the later expansion of different types of clamps, enhancing the expandability and service life of the device.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please refer to Figure 1-4 A novel robotic arm according to this embodiment includes a telescopic cylinder 1, a rotating assembly 2 fixedly installed at the bottom of the telescopic cylinder 1, and an installation mechanism 3 fixedly installed at the bottom of the rotating assembly 2 in a ring at equal intervals. A pneumatic industrial gripper 5, a pointed tool 8 and a pneumatic industrial suction cup 4 are respectively installed at the bottom of the rotating assembly 2 through the installation mechanism 3.

[0027] The rotating assembly 2 includes a base plate 21, which is fixedly mounted on the bottom output end of the telescopic cylinder 1. A drive motor 22 is fixedly mounted on the bottom of the base plate 21, and a fixed plate 23 is fixedly mounted on the output end of the drive motor 22. A semi-circular block 24 is fixedly mounted on the bottom of the fixed plate 23. The mounting mechanism 3 is arranged in a ring at equal intervals and fixedly mounted on the side of the outer surface of the semi-circular block 24 away from the drive motor 22. During the application of this device, the combination of the telescopic cylinder 1 and the rotating assembly 2 allows the robotic arm to extend and retract in the vertical direction while simultaneously rotating the semi-circular block 24 via the drive motor 22, achieving bottom rotation. The circular motion of multiple mounting mechanisms 3 allows for rapid switching between different grippers such as pneumatic industrial grippers 5 and pneumatic industrial suction cups 4 to the work position without the need for manual gripper changes. This design breaks through the limitations of traditional single grippers and can automatically adjust the gripping method according to the type of workpiece (such as metal parts or smooth panels), shortening equipment downtime and improving adaptability to various production scenarios. The ring-shaped mounting mechanisms 3 make full use of the outer surface space of the semi-circular block 24, integrating multiple functions within a limited volume, optimizing the space utilization and operating range of the robotic arm, and balancing structural compactness and functional diversity.

[0028] Please refer to Figures 1-3 A protective shell 25 is fixedly installed at the bottom of the base plate 21, covering the outside of the drive motor 22. The protective shell 25 completely covers the drive motor 22, forming a physical protective barrier. During the operation of the robotic arm, the protective shell 25 can effectively prevent foreign objects such as dust, debris, and oil from the production environment from entering the drive motor 22, avoiding the accumulation of impurities that may hinder heat dissipation or cause wear of components. At the same time, the shell can isolate the drive motor 22 from collisions and impacts from other moving parts of the robotic arm, preventing the motor from shifting or becoming loose due to vibration or external forces. In addition, the protective shell 25 can also play a role in sound insulation and noise reduction to a certain extent, reducing the noise generated by the drive motor 22 during operation and ensuring stable operation of the motor, extending its service life, and thus ensuring the reliable operation of the entire rotating assembly 2 and the robotic arm.

[0029] Please refer to Figures 1-4The mounting mechanism 3 includes a fixed base 31, which is arranged in a ring at equal intervals and fixedly mounted on the outer surface of the semicircular block 24 away from the drive motor 22. A sleeve frame 32 is fixedly mounted on the outside of the fixed base 31, and a mounting block 33 is inserted inside the sleeve frame 32. A connecting plate 34 is fixedly mounted on the outside of the mounting block 33. The pneumatic industrial gripper 5, the pointed tool 8, and the pneumatic industrial suction cup 4 are respectively fixedly connected to the outside of the connecting plate 34 at their respective positions near the semicircular block 24. A limit component 35 is fixedly mounted on the outside of the fixed base 31, and the limiting end of the limit component 35 is engaged with the mounting block 33. 5 includes a side frame 351, which is fixedly installed on the outside of the fixed base 31. A limit spring 353 is fixedly connected inside the side frame 351. A movable block 354 is fixedly connected to the end of the limit spring 353. A limit arm 355 is fixedly connected to the outside of the movable block 354. A limit pin 356 is fixedly connected to the outside of the limit arm 355. A limit hole 352 is opened in the middle of the side of the mounting block 33 near the movable block 354. The end of the limit pin 356 is inserted into the limit hole 352. During the application of this device, its mounting mechanism 3 fixes the sleeve 32 and other components through the fixed base 31. The mounting block 24, positioned on the outer surface of the semicircular block 24, provides a base support for the fixture installation. When it is necessary to install the pneumatic industrial gripper 5 or the pneumatic industrial suction cup 4, the mounting block 33 on the outer side of the connecting plate 34 is aligned with the sleeve frame 32 and inserted. During the insertion process, the inclined surface of the mounting block 33 presses against the limiting pin 356, pushing the movable block 354 to compress the limiting spring 353, causing the limiting pin 356 to retract into the side frame 351. When the mounting block 33 is fully inserted into the sleeve frame 32, the limiting hole 352 on it is aligned with the position of the limiting pin 356. At this time, the elastic force generated by the deformation of the limiting spring 353 pushes the movable block 354 to reset, driving... The limiting arm 355 and the limiting pin 356 are inserted into the limiting hole 352 to achieve the locking and fixing of the mounting block 33 and the sleeve 32, thereby stably installing the fixture on the robotic arm. During disassembly, the component connected to the movable block 354 is pulled by external force, so that the limiting pin 356 overcomes the spring force and is pulled out from the limiting hole 352, releasing the limitation on the mounting block 33. The fixture can then be easily pulled out from the sleeve 32 to complete the disassembly operation. The part measurement tool 8 can be replaced with a sharp tool 8, which is a part glue pen. At the same time, its quick installation design allows different tools to be installed according to specific needs, making the overall adaptability stronger.

[0030] Please refer to Figure 4A connecting shaft 357 is fixedly connected to the outer side of the movable block 354. The end of the connecting shaft 357 passes through the side frame 351 and is fixedly connected to an adjusting arm 358. An adjusting handle is fixedly connected to the outer side of the adjusting arm 358. A mounting plate 6 is fixedly installed on the top of the telescopic cylinder 1. Mounting holes 7 are evenly spaced and arranged in a ring on the outer side of the mounting plate 6. The mounting holes 7 are countersunk holes. The movable block 354 of this device is connected to the adjusting arm 358 and the adjusting handle through the connecting shaft 357 to form a manual operation component. When it is necessary to disassemble the clamp, the operator pulls the adjusting handle, which drives the movable block 354 to move outward against the elastic force of the limit spring 353 through the connecting shaft 357, so that the limit pin 356 is disengaged from the mounting. The limiting hole 352 of block 33 releases the mechanical locking state of the clamp, allowing the mounting block 33 to be pulled out from the sleeve 32, thus achieving quick disassembly of the clamp. The adjustable handle provides an easy operating point for applying force, making the disassembly process more labor-saving and convenient. The mounting plate 6 at the top of its telescopic cylinder 1 has a countersunk hole design, which allows the robotic arm to be fixed to other equipment, such as mounting it on the robot body or workbench, using countersunk bolts. The countersunk hole allows the bolt head to be embedded in the mounting plate 6, avoiding bolts protruding from the surface and causing interference or scratches to the operator. At the same time, it ensures that the surface of the mounting plate 6 is in close contact with the equipment mounting surface, improving the stability and reliability of the robotic arm installation, ensuring that it is subjected to uniform force during operation, and reducing vibration or displacement problems caused by loose installation.

[0031] Operating principle and advantages: This robotic arm achieves rapid switching and precise positioning of grippers through the rotating assembly 2 structure design. The drive motor 22 at the bottom of the telescopic cylinder 1 drives the fixed disk 23 and the semi-circular block 24 to rotate, causing multiple mounting mechanisms 3 distributed in a ring on the outer surface of the semi-circular block 24 to rotate synchronously. When it is necessary to change grippers, the drive motor 22 drives the semi-circular block 24 to rotate to the target gripper. During specific applications, it can flexibly adjust the alignment position of the pneumatic industrial gripper 5 or the pneumatic industrial suction cup 4 with the work area to achieve rapid and automated gripper switching. This design breaks through the single gripper limitation of traditional robotic arms and can be quickly adjusted according to work requirements. For example, when processing metal parts, grippers are used for grasping, while when handling smooth panel-shaped workpieces, it can quickly switch to suction cups to achieve non-destructive adsorption. Through rotational adjustment, this robotic arm can quickly complete gripper switching, effectively shortening production line downtime and significantly improving the adaptability and flexibility of the device in multi-variety production scenarios.

[0032] During the application of this device, its installation mechanism 3 adopts a plug-in design of the sleeve frame 32 and the installation block 33. Combined with the elastic snap-fit ​​function of the limit spring 353 of the limit component 35, it can realize the quick assembly and disassembly of the clamp. During installation, the installation block 33 on the outside of the connecting plate 34 is inserted into the sleeve frame 32. During the insertion and installation of the installation block 33, the movable block 354 is adjusted to move outward, causing it to compress the limit spring 353. When the installation block 33 is fully inserted, the limit hole 352 is aligned with the limit pin 356. At this time, the limit on the movable block 354 is released, and the limit spring 353 returns to its original position and pushes the pin. The pin is embedded in the limiting hole 352 to form a mechanical lock. During disassembly, simply adjust and pull the adjusting handle to drive the connecting shaft 357 to disengage the locking pin from the limiting hole 352, and the clamp can be easily removed. This elastic locking structure requires no tools and can be quickly completed by a single person, which greatly improves efficiency compared to traditional connection methods. The limiting spring 353 provides continuous preload to ensure that the clamp is stable and does not loosen during high-speed movement. The modular design supports future expansion, and different types of clamps can be quickly added or replaced according to production needs, further improving the scalability and service life of the device.
