Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, and specifically relates to a manipulator for use in automated equipment. Background Technique

[0002] A manipulator is an automatic operating device used to grasp, transport objects or operate tools according to a fixed program. The greatest advantage of a manipulator is that it can repeat the same action. With the development of technology, the application of robotic arms will also become more and more extensive. A manipulator is a high-tech automatic production equipment developed in recent decades. The accuracy of manipulator operations and the ability to complete operations in various environments are also getting higher and higher. However, since the clamping structure of current manipulators is also made of fixed materials, most clamping structures of manipulators can only clamp specific shapes such as squares or circles, and it is impossible to clamp both square and circular products during actual use, resulting in low versatility of the manipulator. Therefore, we propose a manipulator for use in automated equipment to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment

[0022] As Figure 1 And Figure 2 As shown in [Figures] and [Figures], a manipulator for use in an automated device proposed in an embodiment of the present utility model includes a support base 1. A mounting base 7 is fixed to the top of the support base 1. Mounting holes 8 are formed in a circular array at the top of the mounting base 7. The provided mounting base 7 facilitates the installation and fixation of this manipulator to the automated device. A bidirectional lead screw 2 is rotatably connected between the inner walls on both sides of the support base 1 through bearings. Both ends of the bidirectional lead screw 2 are threadedly connected with moving brackets 3 that are adapted to the threads on its surface. The moving brackets 3 are slidably arranged between the inner walls on both sides of the support base 1. L-shaped plates 4 are fixed to the bottoms of the moving brackets 3. Variable grasping mechanisms 5 are arranged on one side wall of each L-shaped plate 4. A transmission self-locking assembly 6 for driving the bidirectional lead screw 2 to rotate is arranged on the top of the support base 1. When using this manipulator for the automated device, after installing it on the automated device, the variable grasping mechanism 5 can be adjusted to different forms according to the shape of the product to be grasped. Then, the provided transmission self-locking assembly 6 can be used to drive the bidirectional lead screw 2 to rotate. After the bidirectional lead screw 2 rotates, it will drive the two moving brackets 3 to move in opposite directions. After the moving brackets 3 move in opposite directions, they can respectively drive the L-shaped plates 4 to move. Finally, the L-shaped plates 4 can drive the variable grasping mechanisms 5 to perform the grasping operation on the product. Moreover, the motors used on the manipulator are all waterproof and dustproof motors, so that the entire manipulator can be used under certain harsh environmental conditions.

[0023] As Figure 1 And Figure 3 Note: There are some missing figure references in the original text which are represented as " Figure 1 Figure 3 " in the translation. You may need to check and correct them according to the actual figures in the original patent document.As shown, in some embodiments, the variable grasping mechanism 5 includes four support blocks 501 fixed to one side wall of the L-shaped plate 4. A rotating shaft 502 is rotatably connected between two corresponding support blocks 501 through bearings. Three rotating blocks 503 are fixed to the surface of the rotating shaft 502. A clamping plate 504 is fixed to one side wall of the three corresponding rotating blocks 503. Anti-slip rubber pads 508 are fixed to one side wall of each clamping plate 504. The anti-slip rubber pads 508 provided can increase the friction between the clamping plate 504 and the surface of the product to be clamped, so that the product will be more stable during clamping and grasping. Two drive shafts 505 are rotatably connected to the top of the L-shaped plate 4 through bearings. Large gears 506 are fixed to the surface of the drive shafts 505. The two large gears 506 are meshed with each other. Small gears 507 are fixed to the surface of the rotating shaft 502. The small gears 507 are respectively meshed with the corresponding large gears 506. When in use, in this state, when the L-shaped plate 4 moves, it can drive the clamping plate 504 to move to grasp the square product. When it is necessary to clamp and grasp the circular product, the motor can be started to drive one of the drive shafts 505 to rotate. With the cooperation of the two large gears 506 and the two small gears 507, when the drive shaft 505 rotates, it can drive the two rotating shafts 502 to rotate in opposite directions. After the rotating shaft 502 rotates, it will drive the clamping plate 504 to rotate respectively. Then the two clamping plates 504 can be rotated into a V shape, and then the circular product can be clamped and grasped. And when the clamping plate 504 is converted into a V shape, the clamping operation of circular products with different diameters can be realized with the cooperation of the two V-shaped clamping plates 504 on both sides.

[0024] As Figure 2 shown, in some embodiments, the transmission self-locking assembly 6 includes a worm 601 rotatably connected to the top of the support base 1 through a bearing. A worm gear 602 is fixed to the surface of the bidirectional lead screw 2. The worm 601 is meshed with the worm gear 602. Because the transmission between the worm 601 and the worm gear 602 has a self-locking function, the lead screw will not loosen after rotation.

[0025] As Figure 1 shown, in some embodiments, two guide rods 9 are fixed between the inner walls on both sides of the support base 1. Two moving frames 3 slide on the surface of the two guide rods 9 to play a guiding role. When the bidirectional lead screw 2 rotates to drive the moving frame 3 to move, the moving frame 3 can be prevented from rotating synchronously with the bidirectional lead screw 2.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
