Description

Technical Field

[0001] The present invention relates to the field of mechanical arms, and in particular to a multi-end mechanical arm for an intelligent industrial robot. Background Art

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can rely on their own power and control capabilities to achieve various industrial processing and manufacturing functions. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemicals. Some existing industrial robots have relatively simple work content and are mainly responsible for transferring products from one production line to another. The transfer of items between production lines by industrial robots generally includes three sets of actions: grabbing, transferring, and placing. For the transfer action, since existing industrial robots often use multi-axis robots, it is necessary to set up multiple power sources to complete the transfer action, generally more than 3 power sources, and it is necessary to wait until the items are stationary before picking and placing the items. The control program is relatively complicated and affects work efficiency. This has also led to an invisible increase in costs.

[0003] In the existing technology, such as the Chinese authorization announcement number: CN115383729B "A mechanical arm for an intelligent industrial robot", the mechanical arm for an intelligent industrial robot is arranged between a first conveyor line and a second conveyor line, and is used to transfer items on the first conveyor line to the second conveyor line; the mechanical arm for an intelligent industrial robot includes a base, a rotating mechanism and a grasping mechanism, the rotating mechanism is arranged on the base, the rotating mechanism includes a rotating motor, a guide shell, a driving assembly and a sliding assembly, the guide shell has a cavity and a guide hole connected to the cavity, the guide hole has a first guide part and a second guide part, the first guide part and the second guide part are respectively consistent with the conveying directions of the first conveyor line and the second conveyor line, the driving assembly includes a driving plate arranged at the power output end of the rotating motor, and the sliding assembly includes a connecting shaft. The mechanical arm for an intelligent industrial robot only needs one power source to complete the moving action, without the need for a complicated control program, thereby improving work efficiency.

[0004] In the existing technology, when objects are grasped and transferred, since the clamping components are mostly driven by cylinders, the cylinders need to be driven multiple times when the clamping components are to grasp and place objects, which makes the working steps of driving the cylinders relatively frequent, which in turn causes the cylinders to wear out faster during operation, which greatly increases the cost of using the robotic arm. At the same time, since the number of objects that the robotic arm can grasp at a time is limited, the robotic arm needs to continue to make frequent back and forth movements when grasping and transferring a large number of objects, which leads to a relatively low efficiency of the robotic arm's grasping and transfer. At the same time, since the grasping power source and the moving power source of the robotic arm are designed separately, the power transmission structure of the robotic arm is relatively complicated, which in turn greatly increases the installation and maintenance costs of the robotic arm.

[0005] Therefore, it is necessary to provide a multi-end robotic arm for intelligent industrial robots to solve the above technical problems. Summary of the Invention

Specific embodiments

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Please refer to Figure 1-7 . A multi-end robotic arm for intelligent industrial robots includes a base 1. A limit post 7 is fixedly connected to the top of the base 1. The top of the limit post 7 is fixedly connected to a top plate 8. A cylinder 9 is fixedly installed at the bottom of the top plate 8. A limit sleeve 10 is movably sleeved outside the limit post 7. A drive mechanism 11 is arranged on the side of the limit sleeve 10. A slider 12 is movably sleeved inside the limit sleeve 10. A positioning plate 13 is fixedly connected to the bottom of the slider 12. A positioning groove 14 is formed on the side of the positioning plate 13. A turning plate 15 is movably sleeved on the side of the positioning plate 13.

[0030] A first spring 16 is fixedly connected to the side of the flip plate 15, a steel cable 17 is fixedly connected to the side of the flip plate 15, a limit platform 18 is fixedly connected to the bottom of the limit sleeve 10, a limit mechanism 19 is arranged inside the limit platform 18, a lifting platform 20 is fixedly connected to the bottom of the limit platform 18, a clamping mechanism 21 is arranged inside the lifting platform 20, and a reset mechanism 22 is arranged on the top of the lifting platform 20. The limit mechanism 19 includes a limit opening 191 which is opened inside the limit platform 18, a limit groove 192 is opened inside the limit platform 18, the number of the limit openings 191 is two, and the two limit openings 191 are symmetrically distributed with the limit platform 18 as the axis of symmetry. By arranging the limit mechanism 19, when the flip plate 15 is located inside the limit opening 191, the flip plate 15 can be flipped forward, that is, the steel cable 17 is loosened. When the flip plate 15 moves into the limit groove 192, the flip plate 15 can be flipped backward, so that the steel cable 17 can be tightened, that is, the clamping mechanism 21 is driven to open and clamp, thereby achieving the automatic clamping and placing effect of the article, avoiding the problem that the process is relatively complex when the cylinder drives the clamping component, resulting in a great increase in the use cost of the robotic arm, and further greatly reducing the use and maintenance cost of the robotic arm.

[0031] The driving mechanism 11 includes a second motor 111 which is fixedly installed on the side of the limit sleeve 10, and a threaded rod 112 is fixedly connected to the output shaft of the second motor 111. By arranging the driving mechanism 11, the limit platform 18 and the clamping mechanism 21, when clamping multiple articles, the first clamping plate 211 and the second clamping plate 212 are sleeved outside the article to be clamped. At this time, the second motor 111 is started, so that the second motor 111 drives the slider 12 to move through the threaded rod 112, that is, drives the two flip plates 15 to flip, so that the steel cable 17 drives the multiple second clamping plates 212 to flip, and multiple second clamping plates 212 can squeeze multiple articles against the side of the first clamping plate 211, thereby achieving the synchronous clamping effect of multiple articles. At this time, the positioning plate 13 can drive the multiple clamped articles to move horizontally through the lifting platform 20, and further achieve the article clamping and fixing effect, thus greatly improving the clamping and transfer speed of multiple articles, that is, improving the working efficiency of the robotic arm.

[0032] A sliding ball 23 is movably sleeved inside the limit opening 191, the number of the sliding balls 23 is several, and the several sliding balls 23 are evenly distributed on the side of the inner wall of the limit opening 191. By arranging the limit opening 191, when the flip plate 15 slides inside the limit opening 191, the sliding ball 23 can limit the flip plate 15, avoiding the problem that the flip plate 15 rubs against the inner wall of the limit opening 191 when moving, that is, reducing the friction force when the flip plate 15 moves, and thus improving the smoothness of the flip plate 15 when moving.

[0033] A sliding column 24 is movably sleeved on the side of the inner wall of the limiting groove 192, and the number of the sliding columns 24 is several; by arranging the sliding column 24, when the turnover plate 15 moves into the limiting groove 192, the sliding column 24 can limit the moving turnover plate 15, so as to avoid the problem that the turnover plate 15 rubs against the inner wall of the limiting groove 192 when moving, thereby improving the smoothness of the turnover plate 15 when moving in the limiting groove 192.

[0034] The clamping mechanism 21 includes a first clamping plate 211, the first clamping plate 211 is fixedly connected to the bottom of the lifting platform 20, a second clamping plate 212 is movably sleeved inside the lifting platform 20, and the second clamping plate 212 is fixedly sleeved at one end of the steel cable 17; by arranging the clamping mechanism 21, when multiple items need to be clamped simultaneously, the steel cable 17 can simultaneously stretch and tighten multiple second clamping plates 212, so that the tops of the multiple second clamping plates 212 can be turned over synchronously. At this time, the multiple second clamping plates 212 can drive the items to be tightly squeezed against the sides of the multiple first clamping plates 211, thereby achieving the effect of synchronously clamping multiple items.

[0035] An anti-slip strip 25 is fixedly connected to the side of the first clamping plate 211, and the material of the anti-slip strip 25 is rubber; by arranging the anti-slip strip 25, when the clamped item is clamped and transferred, the anti-slip strip 25 can greatly improve the friction between the clamped item and the second clamping plate 212, and the anti-slip strip 25 can perform soft protection on the clamped item through deformation, so as to avoid the problem that the first clamping plate 211 and the second clamping plate 212 are relatively hard and cause damage to the clamped item, thereby achieving the anti-slip and protection effect of the clamped item.

[0036] The reset mechanism 22 includes a positioning block 221, the positioning block 221 is fixedly connected to the top of the lifting platform 20, and a second spring 222 is fixedly connected to the side of the positioning block 221; by arranging the reset mechanism 22, when the clamped item is placed after the clamping and transfer is completed, the second spring 222 can reversely stretch the second clamping plate 212, so that the second clamping plate 212 and the first clamping plate 211 can be opened, thereby achieving the effect of the robotic arm opening and resetting, and further achieving the effect of unloading and placing the clamped item.

[0037] A support frame 2 is fixedly connected to the top of the base 1. A support platform 3 is fixedly sleeved on the top of the support frame 2. A first motor 4 is installed outside the support platform 3. A conveying wheel 5 is fixedly sleeved on the output shaft of the first motor 4. A conveyor belt 6 is movably sleeved outside the conveying wheel 5. The air cylinder 9 is located directly below the top plate 8, and the bottom of the air cylinder 9 is fixedly connected to the top of the limit sleeve 10. The air cylinder 9 is located directly below the top plate 8, and the bottom of the air cylinder 9 is fixedly connected to the top of the limit sleeve 10. By setting the air cylinder 9, when the clamped items need to be lifted and transferred, the air cylinder 9 is started, so that the air cylinder 9 drives the limit sleeve 10 to lift, that is, drives the lifting platform 20 to move up and down through the limit table 18, so that a plurality of clamping plates drive a plurality of clamped items to move up and down, and thus the effect of lifting and transferring a plurality of clamped items is achieved.

[0038] The working principle of a multi-end manipulator for an intelligent industrial robot provided by the present invention is as follows:

[0039] Step 1: First, when clamping multiple items, the first clamping plate 211 and the second clamping plate 212 are sleeved outside the items to be clamped. At this time, the second motor 111 is started, so that the second motor 111 drives the slider 12 to move through the threaded rod 112, that is, drives the two turning plates 15 to turn, so that the steel cable 17 drives a plurality of second clamping plates 212 to turn, prompting a plurality of second clamping plates 212 to squeeze a plurality of items against the side of the first clamping plate 211, thereby achieving the effect of synchronously clamping a plurality of items. At this time, the positioning plate 13 drives a plurality of clamped items to move horizontally through the lifting platform 20, and thus the effect of clamping and fixing the items is achieved, which greatly improves the clamping and transfer speed of multiple items, that is, improves the working efficiency of the manipulator. When the turning plate 15 is located inside the limit port 191, the turning plate 15 turns forward, that is, the effect of loosening the steel cable 17 is achieved. When the turning plate 15 moves into the limit groove 192, the turning plate 15 turns backward, so that the steel cable 17 is tightened, that is, drives the clamping mechanism 21 to open and clamp. When the turning plate 15 slides inside the limit port 191, the sliding ball 23 limits the turning plate 15, so as to avoid the problem of friction between the turning plate 15 and the inner wall of the limit port 191 when the turning plate 15 moves, that is, reduces the friction force when the turning plate 15 moves, thereby improving the smoothness of the turning plate 15 when it moves. When the turning plate 15 moves into the limit groove 192, the sliding column 24 limits the moving turning plate 15, so as to avoid the problem of friction between the turning plate 15 and the inner wall of the limit groove 192 when the turning plate 15 moves, thereby improving the smoothness of the turning plate 15 when it moves inside the limit groove 192;

[0040] Step 2: When multiple items need to be clamped simultaneously, the steel cable 17 can simultaneously stretch and tighten multiple second clamping plates 212, causing the tops of the multiple second clamping plates 212 to flip synchronously. At this time, the multiple second clamping plates 212 can drive the items to be tightly squeezed against the sides of the multiple first clamping plates 211, thus achieving the effect of synchronous clamping of multiple items. When the clamped items are transferred, the anti-slip strips 25 can greatly increase the friction between the clamped items and the second clamping plates 212, and the anti-slip strips 25 can provide soft protection for the clamped items through deformation, avoiding the problem that the relatively hard first clamping plates 211 and second clamping plates 212 cause damage to the clamped items, thus achieving the anti-slip and protection effect for the clamped items. When the clamped items are placed after the clamping and transfer are completed, the second spring 222 can reversely stretch the second clamping plate 212, causing the second clamping plate 212 and the first clamping plate 211 to open, thus achieving the effect of the robotic arm opening and resetting, and further achieving the effect of unloading and placing the clamped items. When the clamped items need to be lifted and transferred, the cylinder 9 is started, causing the cylinder 9 to drive the limit sleeve 10 to lift, that is, driving the lifting platform 20 to move up and down through the limit platform 18, so that the multiple clamping plates can drive the multiple clamped items to move up and down, thus achieving the effect of lifting and transferring multiple clamped items.

[0041] Compared with the related art, a multi-end robotic arm for intelligent industrial robots provided by the present invention has the following beneficial effects:

[0042] By setting the driving mechanism 11, the limit platform 18 and the clamping mechanism 21, when clamping multiple items, the first clamping plate 211 and the second clamping plate 212 are sleeved outside the items to be clamped. At this time, the second motor 111 is started, causing the second motor 111 to drive the slider 12 to move through the threaded rod 112, that is, driving the two flipping plates 15 to flip, causing the steel cable 17 to drive the multiple second clamping plates 212 to flip, and prompting the multiple second clamping plates 212 to squeeze the multiple items against the sides of the first clamping plate 211, thus achieving the effect of synchronous clamping of multiple items. At this time, the positioning plate 13 can drive the multiple clamped items to move horizontally through the lifting platform 20, thus achieving the effect of clamping and fixing the items, greatly improving the clamping and transfer speed of multiple items, that is, improving the working efficiency of the robotic arm.

[0043] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
