[0017] Before clamping and transferring auto parts, the sliding plate 103 in the frame 102 can be moved according to the size of the auto parts, so that the initial position of the mounting plate 104 can be flexibly adjusted according to the size of the auto parts, which can effectively achieve that auto parts with large size differences can be grasped and moved by the manipulator. When the auto parts to be grasped are of smaller size, most of the sliding plate 103 are stored in the frame 102, which can effectively reduce the overall space occupied by the manipulator and make the operation more flexible. The adjusted sliding plate 103 can be fixed by a limit assembly. When the auto parts need to be clamped, the frame 102 can be driven by the robot arm 101 to move above the auto parts to be grasped, and the mounting plate 104 can be driven to move by the pushing assembly. The clamping operation of the auto parts can be achieved through the clamping assembly in the mounting plate 104, which is very convenient to use.

[0018] As an embodiment of the present invention, please refer to Figure 3 , Figure 4 and Figure 5The pushing assembly includes a moving plate 202 slidably arranged on the outside of the limit rod 106, and the moving plate 202 is located in the mounting port 107. A telescopic cylinder 201 is fixedly arranged on the outer wall of one side of the sliding plate 103, and the telescopic end of the telescopic cylinder 201 is connected to the moving plate 202. A first spring 203 is sleeved on the outer side of the limit rod 106. One end of the first spring 203 is connected to the moving plate 202, and the other end of the first spring 203 is connected to the mounting plate 104. The moving plate 202 can be driven to move by the telescopic cylinder 201, and the moving plate 202 can be pulled to move together with the mounting plate 104 by the first spring 203. When the clamping assembly in the mounting plate 104 contacts the automotive accessories, as the moving plate 202 moves further, the first spring 203 will be stretched, so that the clamping assembly can apply a clamping force to the automotive accessories to achieve the clamping purpose, and the clamping force can be controlled by the deformation of the first spring 203, and the use effect is better.

[0019] As an embodiment of the present invention, please refer to Figure 3 , Figure 4 and Figure 5 A screw rod 204 is also fixedly provided on the outer wall of one side of the movable plate 202 close to the mounting plate 104, and the screw rod 204 penetrates the mounting plate 104, and an adjusting knob 205 is threadedly connected to the outer side of the screw rod 204, and a touch switch 206 is fixedly provided on the outer wall of one side of the mounting plate 104 facing the adjusting knob 205, which is used to control the telescopic cylinder 201 to stop telescoping when the adjusting knob 205 contacts the touch switch 206. When the movable plate 202 moves, the screw rod 204 moves therewith, and when the adjusting knob 205 on the outside of the screw rod 204 contacts the touch switch 206, the telescopic cylinder 201 can be prompted to stop telescoping and maintain a constant clamping force, and the position of the adjusting knob 205 on the outside of the screw 204 can be flexibly adjusted by rotation, which can achieve the purpose of adjusting the clamping force and has a better use effect.

[0020] As an embodiment of the present invention, please refer to Figure 3 and Figure 6The clamping assembly includes a clamping plate 303, an outer wall of the mounting plate 104 is provided with a movable opening 301, the clamping plate 303 is located in the movable opening 301, and the outer walls on both sides of the clamping plate 303 are fixedly provided with limit strips 304, the inner walls on both sides of the movable opening 301 are provided with limit grooves 302, and the limit strips 304 are slidably arranged in the limit grooves 302, and the limit grooves 302 are smeared with lubricating oil, which can improve the smoothness of the limit strips 304 when moving. A clamping module is also provided in the clamping plate 303, and a touch switch 2 311 is fixedly provided on the top inner wall of the movable opening 301, which is used when the clamping plate 303 contacts the touch switch 2 311 The telescopic cylinder 201 is controlled to retract. When the mounting plate 104 moves toward the auto part, the clamping module on the clamping plate 303 will contact the auto part, and the clamping effect will be played through the clamping module. In the process of placing the auto part, the auto part will first contact the placement surface. As the frame 102 moves further downward, the clamping plate 303 will move upward in the movable opening 301 until the clamping plate 303 contacts the touch switch 2 311, which will control the telescopic cylinder 201 to retract, so that the clamping plate 303 is away from the auto part to release the clamping of the auto part, effectively realizing that the auto part will not be clamped until it is stably placed, and the use effect is better.

[0021] As an embodiment of the present invention, please refer to Figure 3 and Figure 6 The clamping module includes a clamping rod 306, and the outer wall of the clamping plate 303 is provided with a fixing opening distributed in a rectangular array, and the clamping rod 306 is movably arranged in the fixing opening, a gasket 307 is fixedly arranged at one end of the clamping rod 306, and a movable rod 308 is fixedly arranged at the other end of the clamping rod 306, and an installation frame 305 is also fixedly arranged on the outer wall of the clamping plate 303, and the movable rod 308 passes through the installation frame 305, and a blocking piece 309 is fixedly arranged at the end of the movable rod 308, and a second spring 310 is sleeved on the outer side of the movable rod 308, and the second spring 310 One end is connected to the mounting frame 305, and the other end of the second spring 310 is connected to the baffle 309. During the clamping process, the gasket 307 at the end of the clamping rod 306 will contact the auto part and drive the movable rod 308 to move in the mounting frame 305, so that the second spring 310 is stretched, and the clamping rod 306 applies a clamping force to the auto part. When there are depressions on both sides of the auto part, part of the end of the clamping rod 306 will enter the depression on one side of the auto part, thereby making the clamped auto part less likely to fall off and having a better use effect.

[0022] As an embodiment of the present invention, please refer to Figure 1A distance sensor 108 is also fixedly provided on the lower surface of the sliding plate 103. The distance sensor 108 can monitor the distance between the sliding plate 103 and the placement surface. When the values ​​detected by all the distance sensors 108 are consistent, it indicates that the frame 102 is parallel to the placement surface at this time, which can effectively improve the stability when placing auto parts and achieve better use effect.

[0023] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 4 The limit assembly includes a card slot 401 equidistantly provided on the upper surface of the sliding plate 103, and a card member 402 is also movably provided on the outer wall of the frame 102. The bottom end of the card member 402 is provided with an inclined surface 406, and the bottom end of the card member 402 is matched with the card slot 401. The top ends of adjacent card members 402 are connected by a grip rod 405. The side wall of the card member 402 is fixedly provided with a side plate 403. The lower surface of the side plate 403 and the upper surface of the frame 102 are connected by a third spring 404. When adjusting the position of the sliding plate 103, it can be directly pushed into the frame 102. During the pushing process of the sliding plate 103, the slot 401 can continuously lift the clamping member 402, and the third spring 404 can be stretched during the lifting process. When the clamping member 402 moves to the appropriate slot 401, the sliding plate 103 can no longer be pulled outward, which can achieve the purpose of quickly limiting the position of the sliding plate 103. When it is necessary to pull the sliding plate 103 outward to change its position, it is only necessary to hold the handle 405 to lift the clamping member 402 so that the clamping member 402 is moved out of the slot 401, thereby releasing the limit on the sliding plate 103, which is very convenient to use.

[0024] When in use, before clamping and transferring auto parts, the sliding plate 103 in the frame 102 can be moved according to the size of the auto parts, so that the initial position of the mounting plate 104 can be flexibly adjusted according to the size of the auto parts, which can effectively achieve that auto parts with large size differences can be grasped and moved by the manipulator. When the auto parts to be grasped are of smaller size, most of the sliding plate 103 are stored in the frame 102, which can effectively reduce the overall space occupied by the manipulator and make the operation more flexible. The adjusted sliding plate 103 can be fixed by a limit assembly. When it is necessary to clamp auto parts, the frame 102 can be driven by the robot arm 101 to move above the auto parts to be grasped, and the mounting plate 104 can be driven to move by the pushing assembly. The clamping operation of the auto parts can be achieved through the clamping assembly in the mounting plate 104, which is very convenient to use.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
