Description

Technical Field

[0001] The utility model relates to the technical field of mechanical arms, and in particular to a desktop-level mechanical arm base and a mechanical arm thereof. Background Art

[0002] Desktop collaborative robots are robots designed to interact and collaborate directly with human workers in human work environments. They are usually small, lightweight, easy to program and use, and suitable for being placed on a desktop or workbench to perform various tasks. Desktop collaborative robots are widely used in assembly, packaging, testing, handling, and machine-assisted operations. They can improve production efficiency, reduce the labor intensity of workers, improve the quality of work, and can be easily integrated into existing production lines when necessary. With the advancement of technology and market demand, the application scope of collaborative robots is expanding.

[0003] Desktop-level collaborative robotic arms are widely used in desktop operations and small production lines due to their compact structure, easy operation, and high safety. However, desktop-level collaborative robotic arms require stable support and fixation during work. The existing technology mostly fixes the robotic arms by bolts or suction cups. The fixation by suction cups has poor stability. Since the suction cups are made of flexible materials, they will deform during the support process, causing the robotic arm to shake, and the fixation effect is poor, affecting the normal operation of the robotic arm. In addition, bolt fixation requires drilling holes on the desktop for installation, which is not convenient enough and has certain limitations. Therefore, it is necessary to develop a new type of desktop-level collaborative robotic arm fixing base to improve the stability and applicability of the robotic arm. Utility Model Content

[0004] In view of the existing deficiencies, the utility model provides a desktop-level robotic arm base and a robotic arm thereof, which solve the problems raised in the above-mentioned background technology, have the characteristics of good stability, convenient adjustment, simple installation, etc., and are suitable for various desktop-level collaborative robotic arms.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A desktop-level robotic arm base comprises a bottom plate for mounting the robotic arm, wherein the robotic arm is fixed to the bottom plate by bolts, the bottom plate is fixed on the base, and a suction assembly is arranged on the right side of the base.

[0007] Furthermore, the base is configured as a U-shaped structure, and vertical plates are fixedly provided on both the upper and rear sides of the upper end face of the base, a slide rail is installed on the upper side of the vertical plate, and a slider is installed at the bottom of the base plate, and the slider is cooperatively connected with the slide rail.

[0008] Furthermore, a layer of rubber pad is pasted on the bottom surface of the base, multiple groups of adsorption holes are evenly opened on the front and rear sides of the bottom of the base, and the adsorption holes penetrate the rubber pad, and multiple groups of channels are opened on the front and rear sides of the base, and the channels are connected to the adsorption holes.

[0009] Furthermore, the suction assembly includes a suction hose and a suction cylinder. The suction cylinder is arranged on the right side of the base. The suction hose is connected to the front and rear sides of the suction cylinder ring surface. A piston plate is assembled inside the suction cylinder. A screw is fixedly connected to the upper side of the piston plate. A threaded sleeve is embedded inside the upper end surface of the suction cylinder. The screw is threadedly connected to the threaded sleeve, and a handle is fixedly provided at the upper end of the screw.

[0010] Furthermore, the two groups of suction hoses are respectively located at the front and rear sides of the base, and the suction hoses are connected to the channels one by one through multiple groups of plug-in short tubes.

[0011] Furthermore, a positioning plate is fixedly provided on the right side of the base plate, a U-shaped groove plate is fixedly provided on the upper end surface of the base, a sliding groove is opened inside the groove plate, a locking bolt is invertedly inserted inside the sliding groove, and the locking bolt passes through the positioning plate and is locked by a threaded knob.

[0012] A robotic arm comprises a desktop-level robotic arm base and a pedestal, wherein the pedestal is fixed to a bottom plate by bolts, a shoulder is arranged on the upper side of the pedestal, a large arm is mounted on the upper side of the shoulder, a small arm is mounted on the upper side of the large arm, the large arm and the small arm are movably connected by an elbow, a wrist part 2 is mounted at the end of the small arm, a wrist part 1 is mounted on the right side of the wrist part 2, and an end effector is mounted on the front side of the wrist part 1.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model realizes the sliding adjustment of the bottom plate on the base through the cooperation of the slide rail and the slider, thereby improving the flexibility of the use of the robotic arm. The rubber pad pasted on the bottom surface of the base and the adsorption holes opened, combined with the suction component, can realize the firm fixation between the base and the desktop, thereby improving the supporting stability of the robotic arm. There is no need to punch holes on the desktop for installation, which is convenient to operate, simple in structure, and easy to install. It is suitable for the fixing needs of various desktop-level robotic arms.

[0015] 2. The base in the utility model is configured as a U-shaped structure. This design can reduce the weight of the base while ensuring the stability of the base. Vertical plates are fixed on both the front and rear sides of the upper end face of the base. A slide rail is installed on the upper side of the vertical plate. A slider is installed at the bottom of the base plate. The slider is connected to the slide rail. This design allows the base plate to slide on the slide rail through the cooperation of the slider and the slide rail, which is convenient for adjusting the position of the robot arm and improves the flexibility of the position adjustment of the robot arm.

[0016] 3. A layer of rubber pad is pasted on the bottom of the base. The rubber pad is supported by rubber material, which can increase the friction between the base and the desktop, improve the anti-slip performance, prevent the base from sliding when the robotic arm is working, and absorb vibration and impact to a certain extent to protect the desktop from damage.

[0017] 4. Multiple groups of adsorption holes are evenly set on the front and back sides of the bottom of the base, and the adsorption holes penetrate the rubber pad. Multiple groups of channels are set on the front and back sides of the base, and the channels are connected to the adsorption holes. Through the multiple groups of adsorption holes, the suction components can form negative pressure inside, so that the base is firmly adsorbed on the desktop to ensure the stability of the base. The evenly distributed multiple groups of adsorption holes can provide a wider adsorption area to ensure the stability of adsorption. This adsorption fixation method does not require drilling holes on the desktop, and installation and disassembly are more convenient.

[0018] 5. The suction assembly is set up to extract the air in the adsorption hole, so that negative pressure is formed inside the adsorption hole, and the base is tightly adsorbed on the desktop, thereby ensuring the stable operation of the robot arm. When the user needs to fix the base, the handle is rotated to drive the screw to rise, and then the piston plate is pulled upward. As the piston plate moves upward, the air in the adsorption hole is sucked into the suction cylinder, so that negative pressure is formed in the adsorption hole. At this time, the base is tightly pressed on the desktop through the negative pressure suction force, achieving a stable fixing effect. Conversely, when the user needs to release the fixation, just rotate the handle in the opposite direction to move the screw and the piston plate downward, the negative pressure in the adsorption hole disappears, and the base can be easily removed.

[0019] 6. The utility model forms a locking mechanism through the positioning plate, slot plate, locking bolt and threaded knob, which can lock and fix the position of the base plate to ensure the accurate positioning of the robot arm. After the locking bolt is locked by the threaded knob, it can provide a strong locking force to prevent the base plate from moving or shaking during the operation of the robot arm. When the position of the robot arm needs to be fixed, tighten the threaded knob, and cooperate with the locking bolt to generate a clamping force on the base plate to achieve locking of the base plate, thereby keeping the base plate and the robot arm fixed. When the position of the robot arm needs to be adjusted, loosen the threaded knob, move the base plate to drive the robot arm to a new position, and then re-lock it.

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example:

[0030] like Figures 1 to 7 As shown, a desktop-level robotic arm base includes a base plate 3 for installing a robotic arm 1, the robotic arm 1 is fixed to the base plate 3 by bolts, the base plate 3 is fixed on the base 2, and a suction assembly 4 is arranged on the right side of the base 2. This design solves the problem that the prior art mostly fixes the robotic arm 1 by bolts or suction cups, and the fixation by suction cups has poor stability. Since the suction cups are made of flexible material, they will deform during the support process, causing the robotic arm 1 to shake, and the fixing effect is not good, which affects the normal operation of the robotic arm 1. In addition, fixing by bolts requires drilling holes on the desktop for installation, the operation is not convenient enough, and there are certain limitations.

[0031] The base 2 is configured as a U-shaped structure. This design can reduce the weight of the base 2 while ensuring the stability of the base 2. Vertical plates 21 are fixed on both the front and rear sides of the upper end face of the base 2. A slide rail 22 is installed on the upper side of the vertical plate 21. A slider 31 is installed at the bottom of the base plate 3. The slider 31 is connected to the slide rail 22. This design allows the base plate 3 to slide on the slide rail 22 through the cooperation between the slider 31 and the slide rail 22, which facilitates the position adjustment of the robot arm 1 and improves the flexibility of the position adjustment of the robot arm 1.

[0032] A layer of rubber pad 23 is pasted on the bottom surface of the base 2. The rubber pad 23 is supported by rubber material and can increase the friction between the base 2 and the desktop, improve the anti-slip performance, prevent the base 2 from sliding when the robot arm 1 is working, and can absorb vibration and impact to a certain extent to protect the desktop from damage. Multiple groups of adsorption holes 24 are evenly arranged on the front and rear sides of the bottom of the base 2, and the adsorption holes 24 penetrate the rubber pad 23. Multiple groups of channels 25 are arranged on the front and rear sides of the base 2, and the channels 25 are connected to the adsorption holes 24. The multiple groups of adsorption holes 24 can cooperate with the suction component 4 to form negative pressure inside, so that the base 2 is firmly adsorbed on the desktop to ensure the stability of the base 2, and the multiple groups of adsorption holes 24 evenly distributed can provide a wider adsorption area to ensure the stability of adsorption. This adsorption fixation method does not require drilling holes on the desktop, and installation and disassembly are more convenient.

[0033] The suction assembly 4 includes a suction hose 41 and a suction cylinder 42. The suction cylinder 42 is arranged on the right side of the base 2. The suction hose 41 is connected to both the front and rear sides of the suction cylinder 42. A piston plate 43 is installed inside the suction cylinder 42. A screw 44 is fixedly connected to the upper side of the piston plate 43. A threaded sleeve 45 is embedded inside the upper end surface of the suction cylinder 42. The screw 44 is screwed to the threaded sleeve 45. A handle 46 is fixed to the upper end of the screw 44. The suction assembly 4 can be set to extract the air in the adsorption hole 24, so that a negative pressure is formed inside the adsorption hole 24, and the base 2 is tightly adsorbed on the desktop, thereby ensuring the stable operation of the robot arm 1. When the user needs to fix the base 2, the screw 44 is driven upward by rotating the handle 46, and then the piston plate 43 is pulled upward. As the piston plate 43 moves upward, the air in the adsorption hole 24 is sucked into the suction cylinder 42, so that negative pressure is formed in the adsorption hole 24. At this time, the base 2 is tightly pressed on the desktop by the negative pressure suction force, achieving a stable fixing effect. Conversely, when the user needs to release the fixation, he only needs to rotate the handle 46 in the opposite direction to move the screw 44 and the piston plate 43 downward, the negative pressure in the adsorption hole 24 disappears, and the base 2 can be easily removed.

[0034] Two groups of suction hoses 41 are respectively located at the front and rear sides of the base 2, and the suction hoses 41 are connected to the holes 25 one by one through multiple groups of plug-in short tubes 411. This design can flexibly connect the suction hoses 41 to the holes 25 on the side of the base 2 by using multiple groups of plug-in short tubes 411. The connection method is simple and easy to operate, which is convenient for users to quickly disassemble and assemble during installation and maintenance.

[0035] A positioning plate 32 is fixedly arranged on the right side of the bottom plate 3, and a slot plate 33 of a U-shaped structure is fixedly arranged on the upper end surface of the base 2. A slide groove 34 is provided inside the slot plate 33, and a locking bolt 36 is inserted inverted inside the slide groove 34. The locking bolt 36 penetrates the positioning plate 32 and is locked by a threaded knob 35. The design forms a locking mechanism by the positioning plate 32, the slot plate 33, the locking bolt 36 and the threaded knob 35, which can lock and fix the position of the bottom plate 3 to ensure the accurate positioning of the mechanical arm 1. After the locking bolt 36 is locked by the threaded knob 35, it can provide a strong locking force to prevent the bottom plate 3 from moving or shaking during the operation of the mechanical arm 1. When the position of the mechanical arm 1 needs to be fixed, the threaded knob 35 is tightened, and the locking bolt 36 is used to generate a clamping force on the bottom plate 3 to lock the bottom plate 3, thereby keeping the bottom plate 3 and the mechanical arm 1 fixed. When the position of the mechanical arm 1 needs to be adjusted, the threaded knob 35 is loosened, the bottom plate 3 is moved to drive the mechanical arm 1 to move to a new position, and then re-locked.

[0036] A mechanical arm includes a desktop-level mechanical arm base and a base 18. The base 18 is fixed to a bottom plate 3 by bolts. A shoulder 17 is arranged on the upper side of the base 18. A large arm 16 is mounted on the upper side of the shoulder 17. A small arm 14 is mounted on the upper side of the large arm 16. The large arm 16 and the small arm 14 are movably connected by an elbow 15. A wrist 2 12 is mounted on the end of the small arm 14. A wrist 1 11 is mounted on the right side of the wrist 2 12. An end effector is mounted on the front side of the wrist 11. The base 18 is used to support and fix the entire mechanical arm 1. The shoulder 17 is the first joint of the mechanical arm 1, and is used to control the large arm 16 to rotate on the shoulder 17. The small arm 14 can be controlled to rotate along the large arm 16 through the elbow 15. The end effector can be driven to rotate in different directions through the wrist 11 and the wrist 2 12. The end effector is the part of the mechanical arm 1 that directly interacts with the environment and is used to cooperate with the staff to complete the final operation.
