Abstract
Description
Technical Field
[0001] This utility model relates to the field of robotic arm technology, and more specifically, to a robotic arm device with a clamping mechanism. Background Technology
[0002] In the field of automated production and material handling, robotic arms, as core execution devices, are widely used in various industrial scenarios. Different production conditions have put forward diverse requirements for the gripping and operation methods of robotic arms. Most existing robotic arm devices are equipped with only a single type of end effector. When production conditions change and different types of objects need to be grasped, it is often necessary to replace the entire end effector or use multiple robotic arms with different types of actuators. This not only increases equipment costs and downtime but also reduces production efficiency. Therefore, we propose an improvement by creating a robotic arm device with a gripping mechanism.

Each rotary cylinder has a connecting seat connected to its rotating end. A vacuum suction cup and a connecting piece are installed on the connecting seat. A clamping block is connected to the connecting piece. The connecting seat is used to rotate under the drive of the rotary cylinders to adjust the position of the vacuum suction cup and the clamping block, thereby realizing the switching between the vacuum suction cup and the clamping block.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0019] For an example, please refer to... Figures 1-4 A robotic arm device with a gripping mechanism includes a robotic arm body 1. The execution end of the robotic arm body 1 is connected to a gripping mechanism body 2. The gripping mechanism body 2 includes a drive structure connected to the execution end of the robotic arm body 1. The drive structure is connected to two rotary cylinders 206. Each rotary cylinder 206 has a connecting seat 207 connected to its rotating end. A vacuum suction cup 208 and a connecting component are mounted on the connecting seat 207. A clamping block 210 is connected to the connecting component. The connecting seat 207 is used to rotate under the drive of the rotary cylinders 206 to adjust the position of the vacuum suction cup 208 and the clamping block 210, thereby switching between the vacuum suction cup 208 and the clamping block 210. The switching process is simple and fast, without the need for long downtime for replacement. The appropriate gripping method can be quickly selected according to different working conditions, shortening the preparation time in the production process and improving production efficiency.
[0020] Furthermore, the connector includes several connecting rods 209 fixedly connected to the connecting seat 207. The end of the connecting rod 209 away from the connecting seat 207 is connected to the clamping block 210. The connecting rods 209 are welded together with the connecting seat 207, and the connecting rods 209 are bolted to the clamping block 210. Since the connecting rods 209 and the clamping block 210 are bolted together, the clamping block 210 can be disassembled and replaced.
[0021] Furthermore, an anti-slip pad 211 is provided on the side of the clamping block 210 away from the connecting seat 207. The anti-slip pad 211 is made of silicone and has anti-slip texture on its surface. The anti-slip pad 211 is bonded to the clamping block 210 with glue or fixed with bolts. The anti-slip pad 211 is used to isolate the clamping block 210 from the workpiece. On the one hand, it can reduce the possibility of the clamping block 210 scratching the workpiece, and on the other hand, it can play an anti-slip role.
[0022] Furthermore, the drive structure includes a mounting plate 201 installed on the execution end of the robotic arm body 1. Two linear cylinders 202 are mounted on the mounting plate 201. The piston rods of the two linear cylinders 202 are connected to a connecting plate 203, and the connecting plate 203 is connected to a rotary cylinder 206. The linear cylinders 202 are used to drive the connecting plate 203 to move horizontally, thereby driving the rotary cylinder 206, connecting seat 207, vacuum suction cup 208, and clamping block 210 to move horizontally, so that the connecting seat 207 moves closer to or away from the workpiece.
[0023] Furthermore, the rotary cylinder 206 is connected to the connecting plate 203 and the connecting seat 207 by bolts.
[0024] Furthermore, a limiting component is provided between the mounting plate 201 and the two connecting plates 203; the limiting component includes a slide rail 205 mounted on the mounting plate 201, and two sliders 204 are slidably connected on the slide rail 205. The two sliders 204 are respectively connected to the two connecting plates 203. The sliders 204 and the slide rail 205 cooperate with each other to limit the movement trajectory of the connecting plate 203, so as to improve the stability of the connecting plate 203 when it moves.
[0025] Furthermore, the mounting plate 201 is connected to the robotic arm body 1, the linear cylinder 202, and the slide rail 205 by bolts.
[0026] The main body of the robotic arm 1, the linear cylinder 202, the rotary cylinder 206, and the vacuum suction cup 208 are all existing components, and their specific structures and control methods are all existing technologies, which will not be described in detail in this application.
[0027] The robotic arm device with a clamping mechanism provided by this utility model is used as follows: Linear cylinder 202 first drives connecting plate 203 to move in the direction of linear cylinder 202 to prevent connecting seat 207 from interfering with surrounding structures during rotation. Then, rotary cylinder 206 drives connecting seat 207 to rotate to adjust the position of vacuum suction cup 208 and clamping block 210. Clamping block 210 or vacuum suction cup 208 can be selected according to the actual situation. Figure 3 and Figure 4 As shown, after selection, when operating the workpiece, the main body 1 of the robotic arm drives the main body 2 of the clamping mechanism to move, so that the vacuum suction cup 208 or the clamping block 210 reaches the workpiece. The linear cylinder 202 pushes the connecting plate 203 to move, and the connecting plate 203 drives the rotary cylinder 206 and the connecting seat 207 to move, so that the vacuum suction cup 208 contacts the surface of the workpiece and draws a vacuum to achieve adsorption, or the anti-slip pads 211 on the two clamping blocks 210 adhere to both sides of the workpiece, and the linear cylinder 202 applies clamping force to achieve fixation. Finally, the main body 1 of the robotic arm and the main body 2 of the clamping mechanism work together to move the workpiece to the target area.
