Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, specifically to a robotic arm automatic detachment and attachment safety lifting device. Background Technology

[0002] A robotic arm is an automated operating device that can mimic certain movements and functions of a human hand and arm to grasp, move objects, or operate tools according to a fixed program. Automatic hooking and unhooking refers to the process of hooking and unhooking through automation technology. Installation and disassembly can be achieved quickly through the automatic hooking and unhooking of robotic arms.

[0003] Currently, hook detachment and reattachment are usually done manually. Due to the large size of the components, climbing ladders and working at heights is required, which is unsafe and inefficient. Using automatic hook detachment and reattachment can effectively improve the lifting of components.

[0004] To address the aforementioned issues, a robotic arm is proposed for automatically attaching and detaching safety lifting devices. Utility Model Content

[0005] The purpose of this invention is to provide a robotic arm that can automatically attach and detach safety lifting devices, solving the problem in the prior art where manual attachment and detachment of lifting devices is required.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic lifting safety device for robotic arms, comprising: a first arm and a second arm; a locking mechanism located on the outer side wall of the first arm; and an insertion mechanism located on the outer side wall of the second arm. The first arm and the second arm are distributed on the same horizontal line. The locking mechanism includes a clamping mechanism and a limiting mechanism. The clamping mechanism includes a locking block, a locking rod, a locking cylinder, and a locking element. A locking block is fixedly connected to the outer side wall of the first arm. A locking cylinder is rotatably connected inside the locking block. A locking rod is threadedly connected inside the locking cylinder. A locking element is fixedly connected to the end of the locking rod away from the locking cylinder. A limiting strip is fixedly connected to one end of the locking cylinder. The locking element is slidably connected to the limiting strip. A transmission belt is sleeved on the outer side wall of the locking cylinder.

[0007] As a further description of the above technical solution: the insertion mechanism includes a base and a rod, the base is adapted to the locking block, and the upper surface of the base is connected to a gear by a motor rotation, the gear being meshed with a transmission belt.

[0008] As a further description of the above technical solution: the limiting mechanism includes a limiting component and a limiting plate. The limiting component is fixedly connected to the outer wall of the base, and the limiting plate is rotatably connected to the inside of the limiting component. The limiting plate is adapted to the locking block.

[0009] As a further description of the above technical solution: the first arm and the second arm are detached and connected.

[0010] As a further description of the above technical solution: an L-shaped component is fixedly connected to the outer wall of the second arm, and the top end of the L-shaped component is rotatably connected to the base.

[0011] As a further description of the above technical solution: the outer side wall of the limiting plate is provided with a spring groove, and the inside of the spring groove is slidably connected to a limiting post by a spring; the outer side wall of the locking block is provided with a limiting hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model provides an automatic lifting and unloading safety device for robotic arms. The device completes the safe lifting operation through a first arm and a second arm. After the second arm is inserted into the first arm, the insertion mechanism is located within the locking block of the locking mechanism. Then, a motor drives a gear to rotate, causing a transmission belt to rotate the locking cylinder. Due to the limiting strip, the locking component moves relative to the insertion rod, making it contact and fix. Simultaneously, the limiting plate is compressed to make it parallel to the locking block, and a spring pops out the limiting post, inserting it into the limiting hole for secondary fixing and achieving tight fixation. When removal is needed, the limiting post is separated from the limiting hole, and then the motor reverses, causing the second arm to descend under gravity, completing rapid removal and suspension.

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.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 A robotic arm for automatically attaching and detaching safety lifting devices includes: a first arm 1 and a second arm 2; a locking mechanism 3 located on the outer side wall of the first arm 1; and an insertion mechanism 4 located on the outer side wall of the second arm 2. The first arm 1 and the second arm 2 are distributed on the same horizontal line. The locking mechanism 3 includes a clamping mechanism 5 and a limiting mechanism 6. The clamping mechanism 5 includes a locking block 501, a locking rod 502, a locking cylinder 503, and a locking element 504. The locking block 501 is fixedly connected to the outer side wall of the first arm 1. The locking cylinder 503 is rotatably connected inside the locking block 501. The locking rod 502 is threadedly connected inside the locking cylinder 503. The locking rod 502 is located away from the locking element. A locking element 504 is fixedly connected to one end of the fixed cylinder 503, and a limiting strip 505 is fixedly connected to one end of the locking cylinder 503. The locking element 504 and the limiting strip 505 are slidably connected. A transmission belt 506 is sleeved on the outer wall of the locking cylinder 503. The first arm body 1 and the second arm body 2 are detachably connected. An L-shaped element 7 is fixedly connected to the outer wall of the second arm body 2. The top end of the L-shaped element 7 is rotatably connected to the base 401. The locking mechanism 3 is inserted through the insertion mechanism 4. Then, the internal transmission belt 506 moves to drive the locking cylinder 503 to rotate, so that the locking rod 502 moves relative to it, thereby fixing the locking element 504 to the insertion mechanism 4 and completing the subsequent tightening to prevent it from falling off.

[0022] Combination Figure 1The insertion mechanism 4 includes a base 401 and a rod 402. The base 401 is adapted to the locking block 501. The upper surface of the base 401 is rotatably connected to a gear 404 via a motor 403. The gear 404 is meshed with a transmission belt 506. The limiting mechanism 6 includes a limiting member 601 and a limiting plate 602. The limiting member 601 is fixedly connected to the outer wall of the base 401. The limiting plate 602 is rotatably connected to the inside of the limiting member 601. The limiting plate 602 is adapted to the locking block 501. After the base 401 is inserted, the gear 404 contacts the transmission belt 506. Then the motor 403 rotates, causing the transmission belt 506 to rotate, thereby realizing the transmission of the locking cylinder 503 and fixing the rod 402. The rod 402 is a long rod with a groove on its surface, which facilitates the limiting of the locking member 504.

[0023] Combination Figure 4 The outer side wall of the limiting plate 602 is provided with a spring groove 8. The inside of the spring groove 8 is slidably connected to the limiting post 10 by a spring 9. The outer side wall of the locking block 501 is provided with a limiting hole 11. The spring 9 pops out the limiting post 10 and inserts it into the limiting hole 11, and then completes the secondary fixation.

[0024] Working principle: The second arm body 2 is inserted into the first arm body 1, and then inserted into the locking mechanism 3 through the insertion mechanism 4. Then, the motor 403 rotates, causing the transmission belt 506 to rotate, which drives the locking cylinder 503 to rotate, causing the locking rod 502 to move relative to it, thereby fixing the locking part 504 to the insertion mechanism 4 and completing the subsequent tightening to prevent it from falling off. At the same time, the limiting plate 602 comes into contact with the locking block 501, making it parallel to the locking block 501. Then, the spring 9 pops out the limiting post 10 and inserts it into the limiting hole 11, thus completing the secondary fixing.

[0025] During disassembly, the limiting post 10 is dislodged, then the motor 403 reverses, the locking part 504 disengages from the insertion rod 402, and gravity causes the second arm 2 to descend and be removed.
