Description

Technical Field

[0001] The present invention relates to the technical field of robotic arms, and specifically to a multi-purpose robotic arm base. Background Art

[0002] A robotic arm is short for a mechanical arm. A mechanical arm is an automated mechanical device that has been most widely and practically applied in the field of robotics technology. Generally, the arm has three motions: telescoping, rotating, and lifting. The rotation and lifting motions are completed by a cross arm and a column.

[0003] The basic function of the arm is to move the gripper to the required position and bear the maximum weight of the workpiece grasped by the gripper, as well as the weight of the arm itself, etc. In addition, it is also related to the fixed stability of the base.

[0004] After retrieval, a Chinese patent with the publication number CN220007847U discloses a robotic arm with a liftable base, which increases the working space range of the mechanical chuck mechanism, and the robotic arm can complete more work contents that can replace manual labor. However, there are still the following problems: 1. When the robotic arm is in use, the base is mostly fixed to the ground to provide overall support for the robotic arm. However, when working on a long workbench, if one robotic arm is used, it can only perform single-item operations at a fixed position. If two or more robotic arms are used, it will increase the cost of the factory. 2. When using a robotic arm with an adjustable position, it is easy to have a situation where the fixed supporting force of the robotic arm is insufficient, resulting in the robotic arm tipping over during use, thus damaging the robotic arm.

In the description of this invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on this invention.

[0026] In this invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0027] Referring to Figures 1-9 , a multi-purpose robotic arm base includes a base main body 1 and a robotic arm main body 4. The robotic arm main body 4 uses a six-axis robotic arm with a model number of UR20. The base main body 1 includes a first base frame 101. A second base frame 102 is fixed to the bottom of the first base frame 101 by bolts. A position adjustment module 2 for changing the robotic arm main body 4 is provided between the inner walls on both sides of the first base frame 101. And a power component for providing power for the movement of the position adjustment module 2 is provided between the inner walls on both sides of the second base frame 102. A connection module 3 for fixing the robotic arm main body 4 is provided between the position adjustment module 2 and the robotic arm main body 4. First, the robotic arm main body 4 is installed on the connection module 3, and then the connection module 3 is combined with the position adjustment module 2. The power component can drive the position adjustment module 2 to move, and further drive the robotic arm main body 4 to move, so as to achieve the purpose of expanding the working range of the robotic arm. At the same time, the connection module 3 can limit its own position with respect to the first base frame 101, so that it is fixed more stably, and the robotic arm main body 4 will not tip over when picking up heavy objects, improving the working stability of the robotic arm.

[0028] Further, the position adjustment module 2 includes two guide rods 104 fixed between the inner walls on both sides of the first chassis 101. A sliding seat 201 is slidably connected to the circumferential outer walls of the two guide rods 104. Two insertion blocks 202 are welded to the top of the sliding seat 201. A slot 205 is formed on one side of the insertion block 202. Limiting components for positioning the connection module 3 are provided on both sides of the sliding seat 201. A fixing component for fixing the connection module 3 is provided at the bottom of the sliding seat 201. Before the connection module 3 contacts the sliding seat 201, first use the limiting components to position the connection module 3 and make the connection module 3 contact the sliding seat 201. At this time, the insertion block 202 will be inserted into the connection module 3, and then use the fixing component to fix the connection module 3, so as to realize the fixed installation of the connection module 3.

[0029] Further, the limiting component includes a positioning frame 203 slid on one side of the sliding seat 201. A first spring 204 is fixed to the bottom of the positioning frame 203 by bolts, and the other end of the first spring 204 is fixed to the sliding seat 201. When the connection module 3 is installed, the positioning of the connection module 3 is realized through the protrusion at one end of the positioning frame 203. That is, during the installation of the connection module 3, the connection module 3 is placed between the two positioning frames 203. When the connection module 3 moves downward for installation, it will push the positioning frame 203 downward, and then compress the first spring 204 to contract and deform, giving the positioning frame 203 a continuously upward force, so as to apply a continuously upward force to the connection module 3. The positioning frame 203 positions the installation of the connection module 3, making it easier for the insertion block 202 to be inserted into the connection module 3 and improving the installation convenience of the device.

[0030] Further, the fixing component includes a groove opened at the bottom of the sliding seat 201. An electric push rod 208 is fixed to the groove by bolts. An avoidance groove 207 is opened at the top of the sliding seat 201. A U-shaped frame 206 fixed to the electric push rod 208 is slidably connected in the avoidance groove 207. After the connection module 3 is connected to the sliding seat 201, start the electric push rod 208. The elongation of the electric push rod 208 will drive the U-shaped frame 206 to move upward in the avoidance groove 207, so that one end of the U-shaped frame 206 contacts the top of the slot 205, thereby fixing the connection module 3 inserted in the slot 205, and thus fixing the position adjustment module 2 and the connection module 3.

[0031] Further, the power component includes a guide rail 105 fixed between the inner walls on both sides of the second chassis 102. A linear motor 106 is provided at the top of the guide rail 105 and is matched with it. The linear motor 106 is fixed to the bottom of the sliding seat 201. Start the linear motor 106 to make the linear motor 106 move on the guide rail 105, and then drive the position adjustment module 2 to move, and then drive the manipulator main body 4 to move, so as to achieve the purpose of expanding the working range of the manipulator main body 4.

[0032] Furthermore, the connection module 3 includes a connection frame 301 disposed on the top of the position adjustment module 2, and the main body of the robotic arm 4 is fixed to the top of the connection frame 301 by bolts. Clamping components for assisting in fixing the connection frame 301 and a support module 5 for assisting in supporting the connection frame 301 are provided on both sides of the connection frame 301. When the connection module 3 is installed, the connection frame 301 will contact the sliding seat 201, and the clamping components are used to assist in positioning the connection frame 301. The support module 5 contacts the ground to support the connection frame 301, expanding the support range of the connection frame 301 and further improving the stability of the main body of the robotic arm 4.

[0033] Further, the clamping assembly includes sliding holes 305 formed on both sides of the connecting frame 301. A U-shaped rod 303 is slidably connected in the sliding hole 305. The inside of the U-shaped rod 303 is a clamping groove 311. The bottoms of one ends of multiple U-shaped rods 303 are all inclined surfaces 304. Limiting rods 103 are fixed on both sides of the first chassis 101 by bolts. Two jacks 302 are formed at the bottom of the connecting frame 301, and the plug blocks 202 can be inserted into the jacks 302. Two symmetrical cavities 306 are formed in the connecting frame 301, and the cavities 306 are respectively communicated with the jacks 302 and the sliding holes 305. The bottom of the cavity 306 is an openable cover plate. Opening the cover plate can place parts in the cavity 306. The shape of the cover plate is the same as that of the cavity 306. Force arms 307 are rotatably connected to the opposite sides of two opposite U-shaped rods 303. The other ends of the two force arms 307 are rotatably connected to an insertion frame 309 that slides in the cavity 306, and the insertion frame 309 can be inserted into the insertion slot 205. A second spring 308 is fixed to one side of the insertion frame 309 by a bolt, and the other end of the second spring 308 is fixed to the cavity 306. A positioning hole 310 is formed at the top of the insertion frame 309, and one end of the U-shaped frame 206 can be inserted into the positioning hole 310. During the installation of the connection module 3, the inclined surface 304 at one end of the U-shaped rod 303 will first contact the limiting rod 103 and squeeze one end of the U-shaped rod 303, causing the U-shaped rod 303 to slide in the sliding hole 305, so that the U-shaped rod 303 can cross over the limiting rod 103 and the limiting rod 103 can be snapped into the clamping groove 311, thereby fixing the connecting frame 301. At the same time, the plug block 202 will be inserted into the jack 302. During the movement of the U-shaped rod 303, the U-shaped rod 303 will pull one end of the force arm 307, so that the other end of the force arm 307 will pull the insertion frame 309 to slide in the cavity 306, causing one end of the insertion frame 309 to move out of the jack 302 and into the cavity 306. At the same time, the insertion frame 309 will squeeze the second spring 308 to contract and generate elastic force. When the limiting rod 103 is snapped into the clamping groove 311, the compressed second spring 308 will reset and push one end of the insertion frame 309 into the insertion slot 205, and the U-shaped frame 206 can be inserted into the positioning hole 310, thereby completing the installation of the connecting frame 301 and assisting in fixing both sides of the connecting frame 301, enabling it to move on the first chassis 101 without tipping over, and further improving the stability of the robotic arm operation.

[0034] Further, the support module 5 includes two fixing rods 501 fixed to both ends of the bottom of the connecting frame 301 by bolts. The bottom end of the fixing rod 501 is rotatably connected to a support rod 502. A connecting rod 505 is rotatably connected between two support rods 502 on the same side. A fixing block 506 is welded to the middle part of the circumferential outer wall of the connecting rod 505. A threaded rod 511 is welded to one side of the fixing block 506. Rotating frames 507 are rotatably connected to the bottoms of both sides of the connecting frame 301. A threaded tube 508 sleeved on the circumferential outer side of the threaded rod 511 is rotatably connected to the bottom of the rotating frame 507, and the threaded tube 508 is threadedly connected to the threaded rod 511. By rotating the threaded tube 508, the threaded rod 511 moves out of or into the threaded tube 508, thereby changing the total length of the threaded tube 508 and the threaded rod 511, thus changing the distance between the connecting rod 505 and the rotating frame 507, thereby driving the support rod 502 to rotate, and further enabling the support rod 502 to contact the ground, providing auxiliary support for the connecting frame 301, reducing the center of gravity of the connecting frame 301 and the main body 4 of the robotic arm, and making the operation of the main body 4 of the robotic arm more stable.

[0035] Further, a plurality of mounting grooves 503 are formed at one ends of the plurality of support rods 502, and balls 504 are rolled in the mounting grooves 503. When the support rod 502 contacts the ground, the balls 504 will replace the support rod 502 to contact the ground, which can reduce the friction between the support rod 502 and the ground and increase the service life of the base.

[0036] Further, a first nut 509 is welded to one end of the threaded tube 508, and a second nut 510 is threadedly connected to the circumferential outer wall of the threaded rod 511. When the length between the threaded tube 508 and the threaded rod 511 does not need to be adjusted, the second nut 510 is rotated to make the second nut 510 contact the first nut 509, thereby providing auxiliary fixation for the threaded tube 508, preventing the threaded tube 508 from rotating and causing the support rod 502 to disengage from the ground and lose support, and improving the stability of the support of the support rod 502.

[0037] The present invention is used in the following steps: S1: First, the main body 4 of the robotic arm is installed on the connecting frame 301, and then the connecting frame 301 is moved above the sliding seat 201, and the connecting frame 301 is moved downward so that the connecting frame 301 is located between the two positioning frames 203; S2: Moving the connecting frame 301 downward will push the positioning frame 203 downward, thereby compressing the first spring 204 to contract and deform, giving the positioning frame 203 a continuously upward force, thereby applying a continuously upward force to the connecting frame 301 to assist in pushing the connecting frame 301 until the inclined surface 304 at one end of the U-shaped rod 303 contacts the limiting rod 103; S3: Continue to move the connecting frame 301 downward. The limiting rod 103 will squeeze the inclined surface 304 at one end of the U-shaped rod 303, causing the U-shaped rod 303 to slide within the sliding hole 305, so that the U-shaped rod 303 can cross over the limiting rod 103 and the limiting rod 103 snaps into the card slot 311, thereby fixing the connecting frame 301. At the same time, when the connecting frame 301 moves downward, the insertion block 202 will be inserted into the insertion hole 302; S4: During the movement of the U-shaped rod 303, the U-shaped rod 303 will pull one end of the lever arm 307, so that the other end of the lever arm 307 pulls the insertion frame 309 to slide within the cavity 306, causing one end of the insertion frame 309 to move out of the insertion hole 302 and into the cavity 306. At the same time, the insertion frame 309 will squeeze the second spring 308 to contract and generate elastic force; S5: When the limiting rod 103 snaps into the card slot 311, the reset of the compressed second spring 308 will push one end of the insertion frame 309 into the insertion slot 205; S6: Start the electric push rod 208. The elongation of the electric push rod 208 will drive the U-shaped frame 206 to move upward within the avoidance slot 207, so that one end of the U-shaped frame 206 passes through the positioning hole 310 on the insertion frame 309 and contacts the top of the insertion slot 205, thereby fixing the insertion frame 309 inserted into the insertion slot 205, and thus completing the fixation of the sliding seat 201 and the connecting frame 301; S7: Rotate the threaded tube 508, so that the threaded rod 511 moves out of or into the threaded tube 508, thereby changing the total length of the threaded tube 508 and the threaded rod 511, thus changing the distance between the connecting rod 505 and the rotating frame 507, thereby pushing the support rod 502 to rotate, and further making the support rod 502 contact the ground to provide auxiliary support for the connecting frame 301; S8: Start the linear motor 106, so that the linear motor 106 moves on the guide rail 105, thereby driving the sliding seat 201 and the connecting frame 301 to move, and further driving the manipulator main body 4 to move, achieving the purpose of expanding the working range of the manipulator main body 4.
