A robot arm with a positioning assembly function

Abstract

This utility model relates to the field of robotics technology and provides a robotic arm with positioning and assembly functions. It includes a base and a frame fixedly connected to the top of the base. The utility model uses a controller to start a motor, causing its output shaft to rotate a lead screw. This allows a movable plate to move downwards along the outer surface of the lead screw, simultaneously moving an L-shaped bar, a movable bar, and a sliding rod downwards. The sliding rod first slides downwards along the inclined section of the guide groove, applying a force to the vertical plate. Simultaneously, it moves the connecting bar, clamping block, and anti-slip rubber pad towards the outer surface of the circular part, clamping and positioning the circular part. At this point, the sliding rod slides from the inclined section of the guide groove to the vertical groove, while the vertical plate remains relatively fixed. This automatic clamping and positioning of the circular part is simple and convenient, thus improving the efficiency of circular part assembly.

Description

Technical Field

[0001] This utility model relates to the field of robotics technology, and in particular to a robotic arm with positioning and assembly functions. Background Technology

[0002] Robots are intelligent mechanical devices capable of automatically performing tasks, possessing the ability to perceive their environment, make decisions, plan, and execute actions. Their core consists of a mechanical body (such as a robotic arm or mobile chassis), sensors (vision / tactile), a control system (algorithms and programs), and a drive mechanism. Unlike traditional machinery, robots can be programmed to adapt to diverse tasks, ranging from automated production lines in industrial fields (welding, assembly) to cleaning and medical assistance in the service industry, and even rescue operations and deep space exploration in special scenarios.

[0003] In existing technologies, when assembling circular parts, robotic arms need to install screws on the circular parts. However, currently, when installing screws on circular parts, workers need to manually operate clamping components to clamp and position the circular parts, which is quite troublesome. This reduces the efficiency of assembling circular parts. Furthermore, the screw installation positions are different for different circular parts, requiring the selection of appropriate robotic arms, which increases the cost of using robotic arms and reduces their applicability. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where, during the assembly of circular parts by a robotic arm, screws need to be installed on the circular parts. However, currently, when installing screws on circular parts, workers need to manually operate clamping components to clamp and position the circular parts, which is quite troublesome and reduces the efficiency of circular part assembly. Furthermore, the screw installation position is different when assembling different circular parts, requiring the selection of a suitable robotic arm, which increases the cost of using the robotic arm and reduces its applicability.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a robotic arm with positioning and assembly functions, comprising: a base, and further comprising:

[0006] A frame is fixedly connected to the top of the base. A lead screw is rotatably connected to the opposite side of the inner wall of the frame. A movable plate is threaded onto the outer surface of the lead screw. A motor is fixedly connected to the top of the frame. The output end of the motor is fixedly connected to one end of the lead screw. A rotating rod is rotatably connected to the bottom of the movable plate. A square frame is fixedly connected to one end of the rotating rod. A movable column is set inside the square frame. An automatic screw-locking mechanism is fixedly connected to the bottom of the movable column. Two vertical plates are symmetrically arranged on the top of the base. A connecting strip is fixedly connected to one side of the vertical plate. A clamping block is fixedly connected to one side of the connecting strip. A guide groove is opened on one side of the vertical plate. An L-shaped strip is fixedly connected to the opposite side of the movable plate. A movable strip is set inside the L-shaped strip. A sliding rod is fixedly connected to one side of the movable strip. One end of the sliding rod is slidably connected inside the guide groove.

[0007] Preferably, the top of the base has two symmetrical convex grooves, and a convex slider is slidably connected inside the convex groove. The convex slider is fixedly connected to the vertical plate. A V-shaped opening is provided on one side of the clamping block, and an anti-slip rubber pad is fixedly connected to the inner wall of the V-shaped opening.

[0008] Preferably, the outer surface of the movable strip is slidably connected to the inside of the L-shaped strip, a limiting rod is slidably connected to one side of the L-shaped strip, and a plurality of limiting holes are equidistantly opened on one side of the movable strip, with one end of the limiting rod slidably connected to the inside of one of the limiting holes.

[0009] Preferably, a spring is provided on the outer surface of the limiting rod, and the spring is fixedly connected to the limiting rod and the L-shaped strip respectively.

[0010] Preferably, the outer surface of the movable plate is slidably connected to the inside of the frame, and the width of the inner wall of the frame is equal to the width of the movable plate.

[0011] Preferably, a second motor is fixedly connected to the top of the movable plate, and the output end of the second motor is fixedly connected to the other end of the rotating rod.

[0012] Preferably, a second lead screw is rotatably connected to the opposite side of the inner wall of the frame, the second lead screw is threadedly connected to the movable column, the outer surface of the movable column is slidably connected to the inside of the frame, and the width of the inner wall of the frame is equal to the width of the movable column.

[0013] Preferably, a motor three is fixedly connected to one side of the frame, and the output end of the motor three is fixedly connected to one end of the lead screw two.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model uses a controller to start a motor, causing its output shaft to drive a lead screw to rotate. Then, under the action of the threaded connection between the lead screw and the movable plate, and with the frame's limiting and guiding effect on the movable plate, the movable plate can move downwards along the outer surface of the lead screw. Simultaneously, this moves the L-shaped strip, movable strip, and sliding rod downwards. The sliding rod first slides downwards along the inclined groove of the guide groove, applying a force to the vertical plate. This causes the vertical plate to drive the convex slider to slide towards the center along the convex groove, simultaneously moving the connecting strip, clamping block, and anti-slip rubber pad towards the outer surface of the circular part, clamping and positioning the circular part. When clamping reaches a certain depth, the sliding rod slides from the inclined groove of the guide groove to the vertical groove, at which point the vertical plate remains relatively fixed. This automatic clamping and positioning of the circular part is simple and convenient, thus improving the efficiency of assembling circular parts.

[0016] 2. This utility model controls the start of motor three via a controller, causing its output shaft to drive the lead screw two to rotate. Then, under the action of the threaded connection between lead screw two and movable column, and with the cooperation of the square frame limiting and guiding the movable column, the movable column can move to one side along the outer surface of the lead screw, synchronously driving the automatic screw-locking mechanism to move to one side. The distance between the automatic screw-locking mechanism and the axis of the rotating rod two is appropriately adjusted. Then, the controller controls the start of motor two, causing its output shaft to drive the rotating rod to rotate, synchronously driving the square frame, movable column, and automatic screw-locking mechanism to rotate. This allows the automatic screw-locking mechanism to install screws at any position on the top of the circular parts, facilitating the assembly of different circular parts, thereby reducing the operating cost of the robot arm and improving its applicability.

[0017] 3. In this utility model, by manually pulling the limiting rod outward, it disengages from the inside of one of the limiting holes, releasing the limitation on the movable strip. Simultaneously, the spring is stretched, allowing the movable strip to slide downward along the inside of the L-shaped strip. This simultaneously drives the sliding rod to slide downward along the inclined groove of the guide groove, applying a force to the vertical plate, causing the two vertical plates to move closer together. Simultaneously, this drives the connecting strip and clamping block to move towards the center, adjusting the initial positions of the connecting strip and clamping block. Then, the limiting rod is released, allowing it to be inserted into the inside of the other limiting hole under the restoring force of the spring, thus limiting and fixing the movable strip. This facilitates the appropriate adjustment of the initial positions of the two clamping blocks according to the different diameters of circular parts, thereby facilitating the subsequent clamping and positioning of circular parts of different diameters.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Examples, such as Figure 1-4As shown, this utility model provides a robotic arm with positioning and assembly functions, including: a base 1, and a frame 2, which is fixedly connected to the top of the base 1. A lead screw 201 is rotatably connected to one side of the inner wall of the frame 2. A movable plate 203 is threadedly connected to the outer surface of the lead screw 201. A motor 202 is fixedly connected to the top of the frame 2. The output end of the motor 202 is fixedly connected to one end of the lead screw 201. A rotating rod 204 is rotatably connected to the bottom of the movable plate 203. A square frame 206 is fixedly connected to one end of the rotating rod 204. The inside of the square frame 206 is provided with... There is a movable column 208, and an automatic screw-locking mechanism 209 is fixedly connected to the bottom of the movable column 208. Two vertical plates 301 are symmetrically arranged on the top of the base 1. A connecting strip 303 is fixedly connected to one side of the vertical plate 301, and a clamping block 304 is fixedly connected to one side of the connecting strip 303. A guide groove 302 is opened on one side of the vertical plate 301. An L-shaped strip 3 is fixedly connected to the opposite side of the movable plate 203. A movable strip 306 is set inside the L-shaped strip 3. A sliding rod 307 is fixedly connected to one side of the movable strip 306. One end of the sliding rod 307 is slidably connected inside the guide groove 302.

[0027] Furthermore, such as Figure 1-4 As shown, two convex grooves 101 are symmetrically opened on the top of the base 1. A convex slider 311 is slidably connected inside the convex groove 101. The convex slider 311 is fixedly connected to the vertical plate 301. A V-shaped opening is provided on one side of the clamping block 304. An anti-slip rubber pad 305 is fixedly connected to the inner wall of the V-shaped opening. With the above arrangement, the convex slider 311 can slide to one side along the inside of the convex groove 101. The V-shaped opening facilitates the clamping block 304 to clamp and position the round parts. The anti-slip rubber pad 305 provides an anti-slip effect during movement.

[0028] Furthermore, such as Figure 1-4 As shown, the outer surface of the movable strip 306 is slidably connected to the inside of the L-shaped strip 3. A limiting rod 309 is slidably connected to one side of the L-shaped strip 3. Multiple limiting holes 308 are equidistantly provided on one side of the movable strip 306. One end of the limiting rod 309 is slidably connected to the inside of one of the limiting holes 308. By pulling the limiting rod 309 outward by hand, it is disengaged from the inside of one of the limiting holes 308, thus releasing the limitation on the movable strip 306. At this time, the movable strip 306 can slide up or down along the inside of the L-shaped strip 3.

[0029] Furthermore, such as Figure 1-4 As shown, a spring 310 is provided on the outer surface of the limiting rod 309. The spring 310 is fixedly connected to the limiting rod 309 and the L-shaped strip 3 respectively. Under the reset force of the spring 310, the limiting rod 309 can be inserted into the interior of another limiting hole 308 to limit and fix the movable strip 306.

[0030] Furthermore, such as Figure 1-4 As shown, the outer surface of the movable plate 203 is slidably connected to the inside of the frame 2. The width of the inner wall of the frame 2 is equal to the width of the movable plate 203. With the above settings, the movable plate 203 can slide up and down along the inside of the frame 2.

[0031] Furthermore, such as Figure 1-4 As shown, a second motor 205 is fixedly connected to the top of the movable plate 203. The output end of the second motor 205 is fixedly connected to the other end of the rotating rod 204. The controller controls the second motor 205 to start, so that its output shaft drives the rotating rod 204 to rotate.

[0032] Furthermore, such as Figure 1-4 As shown, a lead screw 210 is rotatably connected to the opposite side of the inner wall of the frame 206. The lead screw 210 is threadedly connected to the movable column 208. The outer surface of the movable column 208 is slidably connected to the inside of the frame 206. The width of the inner wall of the frame 206 is equal to the width of the movable column 208. With the above arrangement, when the lead screw 210 rotates, the movable column 208 can move to one side along the outer surface of the lead screw 210.

[0033] Furthermore, such as Figure 1-4 As shown, a motor 207 is fixedly connected to one side of the box 206. The output end of the motor 207 is fixedly connected to one end of the lead screw 210. The motor 207 is started by the controller, so that its output shaft drives the lead screw 210 to rotate.

[0034] Working principle: In use, the round parts are placed on the base 1, and the controller starts the motor 202, causing its output shaft to drive the lead screw 201 to rotate. Then, under the action of the threaded connection between the lead screw 201 and the movable plate 203, and with the cooperation of the frame 2 in limiting and guiding the movable plate 203, the movable plate 203 can move downward along the outer surface of the lead screw 201, simultaneously driving the L-shaped bar 3, the movable bar 306, and the slide bar 307 downward. The slide bar 307 first slides downward along the inclined groove of the guide groove 302, and applies a force to the vertical plate 301, causing the vertical plate 301 to drive the convex slider 311 to slide towards the center along the convex slide groove 101, simultaneously driving the connecting bar 303, the clamping block 304, and the anti-slip mechanism. Rubber pad 305 moves towards the outer surface of the circular part to clamp and position it. When clamping reaches a certain point, slide rod 307 slides from the inclined groove of guide groove 302 to the vertical groove. At this time, vertical plate 301 remains relatively fixed. This automatically clamps and positions the circular part, which is simple and convenient, thereby improving the assembly efficiency of the circular part. Simultaneously, the downward movement of movable plate 203 drives rotating rod 204, square frame 206, movable column 208, and automatic screw-locking mechanism 209 to move downward, so that automatic screw-locking mechanism 209 is positioned directly above the circular part where the screw needs to be installed. The controller controls automatic screw-locking mechanism 209 to install the screw into the center of the circular part. The automatic screw-locking mechanism 209 is existing technology and will not be described in detail. The controller starts the motor 207, causing its output shaft to drive the lead screw 210 to rotate. Then, under the action of the threaded connection between the lead screw 210 and the movable column 208, and with the limiting and guiding effect of the frame 206 on the movable column 208, the movable column 208 can move to one side along the outer surface of the lead screw, synchronously driving the automatic screw-locking mechanism 209 to move to one side. The distance between the automatic screw-locking mechanism 209 and the axis of the rotating rod 204 is appropriately adjusted. Then, the controller starts the motor 205, causing its output shaft to drive the rotating rod 204 to rotate, synchronously driving the frame 206, the movable column 208, and the automatic screw-locking mechanism 209 to rotate. This allows the automatic screw-locking mechanism 209 to install screws at any position on the top of the circular parts, facilitating the assembly of different circular parts, thereby reducing the operating cost of the robot arm and improving its applicability. By manually pulling the limiting rod 309 outward, it disengages from the inside of one of the limiting holes 308, releasing the limitation on the movable bar 306. Simultaneously, the spring 310 is stretched, allowing the movable bar 306 to slide downward along the inside of the L-shaped bar 3. Simultaneously, this causes the sliding rod 307 to slide downward along the inclined groove portion of the guide groove 302, applying a force to the vertical plate 301, causing the two vertical plates 301 to move closer together towards the center. Simultaneously, this causes the connecting bar 303 and the clamping block 304 to move towards the center.The initial positions of the connecting bar 303 and the clamping block 304 are adjusted, and then the limiting rod 309 is released, allowing it to be inserted into the other limiting hole 308 under the restoring force of the spring 310, thus limiting and fixing the movable bar 306. This facilitates the appropriate adjustment of the initial positions of the two clamping blocks 304 according to the different diameters of circular parts, thereby facilitating the subsequent clamping and positioning of circular parts of different diameters.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
