[0002] In today's life, with the rapid development of science and technology, the biggest difference between robot arms and human arms is flexibility and endurance. The application of robot arms will become more and more extensive. The manipulator is a high-tech automatic production equipment developed in recent decades. It has the accuracy of operation and the ability to complete operations in the environment. It is an important branch of industrial manipulator robots. The manipulator is an automatic operating device that can imitate certain movements and functions of human hands and arms to grasp, carry objects or operate tools according to fixed procedures. The characteristic is that it can complete various expected operations through programming. The structure and performance have the advantages of both human and mechanical machines. The manipulator is the earliest industrial robot and the earliest modern robot. It can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, it is widely used in machinery manufacturing, metallurgy, electronics, light industry and atomic energy departments;

[0003] The Chinese patent (CN202121492159.1) discloses an automatic loading and unloading manipulator for short-axis parts, which is provided with a driving motor, and uses the power provided by the driving motor to drive the forward and reverse threaded rod to rotate, and the threaded barrel uses the rotation of the forward and reverse threaded rod to drive the positioning block to move inside the positioning groove, and at the same time, the threaded barrel drives the clamping plate to tighten and fix the short-axis parts, thereby increasing the stability of loading or unloading of short-axis parts and avoiding the falling of short-axis parts during loading or unloading. However, the application still has the following technical problems when used: during the continuous loading and unloading work, the clamping surface of the clamping claw of this manipulator is prone to adhere to debris, residues and other debris, resulting in the subsequent loading and unloading work. The residues and debris will be transported together with the parts, and some metal debris will leave scratches on the surface of the parts when clamping the parts, affecting the subsequent processing of the parts;

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, an embodiment of the utility model provides an automatic loading and unloading robot for parts, which is composed of a main mechanism 10 and a cleaning mechanism 20.

[0027] The main body mechanism 10 includes a first mounting plate 11, a first fixed plate 13 and four support rods 18. The four support rods 18 are fixedly connected to one side of the first mounting plate 11 to provide support for the first mounting plate 11, and a weight reduction groove 31 is provided inside the support rod 18 to reduce the overall weight of the utility model and facilitate assembly. An electric guide rail 12 for driving the electric clamping jaw 17 to move horizontally is symmetrically installed on one side of the first mounting plate 11. The movable end of the electric guide rail 12 is fixedly connected to the first fixed plate 13. A mounting frame 14 is fixedly connected to one side of the first fixed plate 13. An electric push rod 15 for driving the electric clamping jaw 17 to move vertically is installed on one side of the mounting frame 14. The piston rod of the rod 15 is fixedly connected to the second mounting plate 34, and the electric clamp 17 is symmetrically installed on one side of the second mounting plate 34. In order to limit the clamping range of the electric clamp 17, a limiting block 37 is fixedly connected to one side of the electric clamp 17, and an anti-slip pad 35 is symmetrically fixedly connected to one side of the electric clamp 17. The anti-slip pad 35 enhances the friction between the contact surface of the electric clamp 17 and the part to prevent the part from falling off during the loading and unloading process. In order to facilitate the position fixing of the utility model, one end of the support rod 18 is fixedly connected to the base plate 32, and two fixing holes 33 are provided inside the base plate 32. The fixing holes 33 are used in conjunction with fixing cones and other components to facilitate the position fixing of the utility model.

[0028] In one embodiment, in order to enhance the stability of the second mounting plate 34 during movement, four telescopic rods 16 are installed on one side of the first fixing plate 13 , and the piston rods of the telescopic rods 16 are fixedly connected to the second mounting plate 34 .

[0029] In one embodiment, in order to facilitate image recognition and recording of loading and unloading parts, an image collector 36 is installed on one side of the second mounting plate 34, and the image collector 36 is connected to the control terminal to collect images of the parts.

[0030] The cleaning mechanism 20 includes a second fixed plate 21, a third fixed plate 24 and a brush plate 26. The brush plate 26 is installed on one side of the third fixed plate 24 and is used to clean the clamping surface of the electric clamp 17. A connecting rod 19 is symmetrically provided on one side of the first mounting plate 11. One end of the connecting rod 19 is fixedly connected to the support rod 18, and one side of the support rod 18 is fixedly connected to the limiting plate 25. One side of the second fixed plate 21 is fixedly connected to the connecting rod 19. A forward and reverse motor 29 is installed on one side of the second fixed plate 21. A screw 22 is installed on the output shaft of the forward and reverse motor 29. One end of the screw 22 is rotatably connected to the limiting plate 25. One side of the screw 22 is sleeved with a threaded sleeve 28, and one side of the threaded sleeve 28 is fixedly connected to the third fixed plate 24. By arranging the screw 22 to cooperate with the threaded sleeve 28, it is convenient to drive the brush plate 26 to move vertically, and it is convenient to adjust its height to prevent the brush plate 26 from affecting the operating range of the electric clamp 17 during loading and unloading.

[0031] In one embodiment, in order to enhance the stability of the third fixing plate 24 during movement, a slide rod 23 is symmetrically fixedly connected to one side of the second fixing plate 21 , a slide sleeve 27 is sleeved on one side of the slide rod 23 , and one side of the slide sleeve 27 is fixedly connected to the third fixing plate 24 .

[0032] Optionally, a U-shaped plate is filled inside the brush plate 26 to enhance its overall hardness and prevent the electric clamp 17 from being unable to be cleaned normally due to deformation of the brush plate 26 .

[0033] When the utility model is working: the height of the brush plate 26 is adjusted by the forward and reverse motor 29 so that it is located in the area below that does not affect the loading and unloading operations of the electric clamp 17, the electric guide rail 12 drives the electric clamp 17 to move horizontally, and the electric push rod 15 drives the electric clamp 17 to move up and down, so that the electric clamp 17 clamps the parts for loading and unloading operations of the parts. After the loading and unloading operations are completed, the forward and reverse motor 29 drives the screw rod 22 to rotate, and cooperates with the threaded sleeve 28 to drive the brush plate 26 to move upward to the limit plate 25, and the electric push rod 15 is retracted to reset the electric clamp 17, and the electric guide rail 12 drives the electric clamp 17 to move toward the brush plate 26, so that the clamping surface of the electric clamp 17 contacts the brush plate 26, and the brush plate 26 removes the residue and debris on the electric clamp 17 to prevent it from affecting subsequent processing.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
