Description

Technical Field

[0001] This utility model relates to the field of adjustment mechanism technology, and in particular to a telescopic pneumatic needle adjustment mechanism for a robotic arm. Background Technology

[0002] In the field of industrial automation, robotic arms are widely used, undertaking key tasks such as material handling and processing operations, greatly improving production efficiency and quality. In many special processing techniques, such as for materials or workpieces that require needle-punching, robotic arms need to be equipped with specialized needle-punching adjustment mechanisms to complete the corresponding tasks.

[0003] However, traditional adjustment methods are mostly manual, which is not only inefficient but also difficult to guarantee accuracy. In addition, for some special materials, such as soft and breathable non-metallic materials, existing needle adjustment mechanisms are difficult to operate stably and efficiently. Therefore, a telescopic pneumatic needle adjustment mechanism for robotic arms was designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a retractable pneumatic needle adjustment mechanism for robotic arms.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A telescopic pneumatic needle-piercing adjustment mechanism for a robotic arm includes a top plate. Side plates are fixedly connected to both sides of the bottom of the top plate. Pneumatic rotating rods are rotatably mounted on the bottom of each of the two side plates. A common cylinder is fixedly connected between the two rotating rods. A needle is fixedly connected to the bottom of the cylinder. Rotating plates are fixedly connected to the outer ends of the two rotating rods through the side plates. Circular holes adapted to the rotating rods are formed on each of the two side plates. Straight holes are formed on each of the two rotating plates. A driving mechanism is provided at the top of each of the two side plates. Vertical holes are formed at the top of each of the two side plates. The driving mechanism includes a connecting plate fixedly connected between the tops of the two side plates, and a second servo motor fixedly connected at the middle of the top of the connecting plate. The output end of the second servo motor is fixedly connected to a lead screw through the connecting plate. A limit block is fixedly connected to the bottom of the lead screw, and a screw block is screwed onto the lead screw. A lead screw nut adapted to the lead screw is fixedly sleeved in the middle of the screw block. Vertical rods are fixedly connected to both ends of the screw block through vertical holes. By rotating the second servo motor in both directions, the lead screw is driven to rotate, so that the screw block drives the vertical rods on both sides to rise or fall.

[0007] Preferably, a limiting sleeve is fixedly connected to the outer side of both side plates, a protruding rod is fixedly connected to the bottom of each vertical rod, and each protruding rod is slidably connected inside the straight hole. Each vertical rod is slidably sleeved inside the adjacent limiting sleeve. By sliding the protruding rod in the straight hole, when the vertical rod is raised or lowered, it can drive the rotating rod to change its angle.

[0008] Preferably, a rotating cylinder is rotatably connected to the middle of the top of the top plate, and a fixing plate is fixedly connected to the top of the rotating cylinder. The fixing plate has fixing holes at all four corners, which facilitates the connection between the device and the robotic arm.

[0009] Preferably, a worm gear is fixedly sleeved on the circumferential surface of the rotating cylinder.

[0010] Preferably, two mounting plates are fixedly connected to one side of the top of the top plate, and the two mounting plates are rotatably connected to the same worm gear, which meshes with a worm wheel.

[0011] Preferably, a first servo motor is fixedly connected to the outer side of one of the mounting plates, and the output end of the first servo motor passes through the mounting plate and is fixedly connected to one end of the worm gear. The rotation of the first servo motor allows the cylinder to rotate on the robotic arm.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing technologies such as cylinders, rotating rods, vertical rods, connecting plates, a first servo motor, a rotating cylinder, and a second servo motor, the rotation of the second servo motor controls the angle adjustment of the cylinder, while the rotation of the first servo motor causes the cylinder to rotate around the robotic arm. Combined with the extension and retraction of the cylinder, this allows for flexible adjustment of the needle insertion, effectively solving the problem of inconvenient needle insertion adjustment mentioned in the background technology. This results in multi-angle and multi-directional adjustment capabilities, adapting to diverse needs for needle insertion position, angle, and depth in different work scenarios, and significantly improving the adaptability of the robotic arm for needle insertion operations.

A cylinder 3 is fixedly connected between the two rotating rods 301. A needle is fixedly connected to the bottom of the cylinder 3. Rotating plates 4 are fixedly connected to the outer ends of the two rotating rods 301 through the side plates 1. Circular holes adapted to the rotating rods 301 are provided on each side plate 1. Straight holes 401 are provided on each rotating plate 4. A driving mechanism is provided at the top of each side plate 1. Vertical holes 101 are provided at the top of each part. The drive mechanism includes a connecting plate 8 fixedly connected between the tops of the two side plates 1. A second servo motor 803 is fixedly connected at the middle of the top of the connecting plate 8. A lead screw 802 is fixedly connected through the connecting plate 8 at the output end of the second servo motor 803. A limit block is fixedly connected at the bottom of the lead screw 802. A screw block 801 is screwed onto the lead screw 802. A lead screw nut that matches the lead screw 802 is fixedly sleeved in the middle of the screw block 801. Vertical rods 5 are fixedly connected through the vertical holes 101 at both ends of the screw block 801.

[0021] In this utility model, a limiting sleeve 102 is fixedly connected to the outer side of both side plates 1, and a protruding rod 501 is fixedly connected to the bottom of each vertical rod 5. Each protruding rod 501 is slidably connected inside the straight hole 401, and each vertical rod 5 is slidably sleeved inside the adjacent limiting sleeve 102. The limiting sleeve 102 can improve the stability of the vertical rod 5.

[0022] In this utility model, a rotating cylinder 6 is rotatably connected to the middle of the top of the top plate 2, and a fixing plate 602 is fixedly connected to the top of the rotating cylinder 6, and fixing holes 603 are provided at the four corners of the fixing plate 602.

[0023] In this utility model, a worm gear 601 is fixedly sleeved on the circumferential surface of the rotating cylinder 6.

[0024] In this utility model, two mounting plates 7 are fixedly connected to one side of the top of the top plate 2. The same worm gear 702 is rotatably connected between the two mounting plates 7, and the worm gear 702 meshes with the worm wheel 601.

[0025] In this utility model, a first servo motor 701 is fixedly connected to the outer side of one of the mounting plates 7, and the output end of the first servo motor 701 passes through the mounting plate 7 and is fixedly connected to one end of the worm gear 702. Through the forward and reverse rotation of the first servo motor 701, the cylinder 3 can mechanically rotate around the arm in both directions.

[0026] Working principle: The device is installed at the bottom of the robotic arm through the fixing hole 603. When it is necessary to adjust the angle between the cylinder 3 and the side plate 1, the second servo motor 803 is started, which controls the rotation direction of the second servo motor 803 through the rotation of the lead screw 802, driving the screw block 801 to rise or fall. This causes the vertical rods 5 on both sides to rise and fall along with the protruding rods 501. Since the protruding rods 501 slide in the straight hole 401, they drive the two rotating plates 4 to rotate around the rotating rod 301 by a certain angle, so that the rotating rod 301 drives the cylinder 3 to adjust the angle. When it is necessary to adjust the direction between the side plate 1 and the top plate 2, the first servo motor 7 is started. 01, causing the worm gear 702 to rotate, which in turn drives the worm wheel 601 to rotate. Since the worm wheel 601, rotating cylinder 6, etc., are fixedly connected to the robotic arm and do not rotate, the top plate 2, along with the side plate 1 and cylinder 3, rotates in the opposite direction. By controlling the first servo motor 701 and the second servo motor 803, the cylinder 3 can be adjusted at any angle, thereby adjusting the needle position and improving practicality. At the same time, when the second servo motor 803 is not running, it is locked by an electromagnetic brake to improve stability. The cylinder 3 is connected to the air pump through a pipeline and a solenoid valve. The extension and retraction of the cylinder 3 controls the extension and retraction of the needle.
