As the driving tube 102 continues to move downward, the bottom surface of the driving tube 102 will contact the LGA bottom cover on the inner wall of the feeding chute 108. Since the suction cup 106 is installed on the bottom surface of the driving tube 102, and the inner wall of the driving tube 102 is in a negative pressure state at this time, the driving tube 102 will adsorb and fix the LGA bottom cover through the negative pressure.

[0035] Reference Figure 1-Figure 10Specifically, the clamping mechanism includes a clamping claw assembly and a driving assembly. The clamping claw assembly includes a rotating groove 3 opened on the outer surface of the device housing 1. The rotating groove 3 is provided with three inner walls of the housing 1 in an annular array. A rotating bearing 301 is fixedly installed on the inner wall of the rotating groove 3. Two rotating bearings 301 are correspondingly distributed on the inner wall of each rotating groove 3. A gear 302 is rotatably installed on the inner wall of the rotating bearing 301. Each gear 302 is meshed with a meshing tooth 105. A clamping claw 303 is correspondingly distributed on the outer surface of each gear 302. An anti-slip rubber 304 is correspondingly distributed on the bottom surface of each clamping claw 303. Each gear 302 is rotationally connected to the inner walls of the two rotating bearings 301. The gear 302 is in rotational contact with the inner wall of the rotating groove 3. The gear 302 is provided with three inner walls of the three rotating grooves 3 in an annular array. A clamping claw 303 is installed on the outer surface of the gear 302. An anti-slip rubber 304 is installed on the bottom surface of the clamping claw 303.

[0036] In the embodiment of the present invention, when the screw drives the meshing tooth 105 to move upward, the gear 302 meshing with it will rotate on the inner wall of the rotating bearing 301, thereby driving the clamping claws 303 installed on the outer surface of the gear 302 to deflect, and finally causing the three clamping claws 303 to move inward and contact with the object to clamp the object, and then the object is driven by the clamping claws through the robotic arm to move to the top surface of the mainboard, and the object is placed at the specified position of the mainboard to assemble the mainboard.

[0037] Reference Figure 1-Figure 10 Specifically, the driving component includes a locating bearing 4, which is installed on the inner wall of the shell 1. The locating bearings 4 are two equidistantly distributed on the inner wall of the shell 1. A ball slider 401 is rotatably installed on the inner wall of the locating bearing 4. The ball slider 401 is rotatably connected to the driving tube 102 through a threaded groove 104. A transmission track 402 is installed on the outer surface of the ball slider 401. The transmission track 402 extends from the inner wall of the shell 1 to the outside of the shell 1. A rotating positioning plate 403 is installed on one side surface of the shell 1. A transmission wheel 404 is rotatably installed on one side surface of the rotating positioning plate 403. The transmission wheel 404 transmits power to each other through the transmission track 402 and the ball slider 401. A driving motor 405 is installed on one side surface of the shell 1, and the output end of the driving motor 405 is fixedly connected to the transmission wheel 404.

[0038] In the embodiment of the present invention, when it is necessary to use a grasping device for installing an LGA bottom cover, the housing 1 is installed at the end of the mechanical arm, and the LGA bottom cover to be installed is installed into the inner wall of the stacking plate 2, so that the LGA bottom cover to be installed is continuously stacked on the inner wall of the stacking plate 2. When it is necessary to install the motherboard, the housing 1 is moved by the mechanical arm and moved to the top surface of the object, and the three clamping claws 303 are at the same height of the object. When it is necessary to clamp the object and install it on the surface of the motherboard, the drive motor 405 is started. When the drive motor 405 is started, it drives the transmission wheel 40 installed at its output end. 4 rotates, and a transmission track 402 is installed on the outer surface of the transmission wheel 404. At this time, the rotating transmission wheel 404 will drive the transmission track 402 to rotate, and the transmission track 402 is at the outer surface of the ball slider 401 at the same time. Therefore, the rotating transmission track 402 will drive the ball slider 401 to rotate on the inner wall of the positioning bearing 4. When the ball slider 401 rotates on the inner wall of the positioning bearing 4, since the inner wall of the ball slider 401 rotates between the inner wall of the ball slider 401 and the threaded groove 104, the driving tube 102 and the meshing teeth 105 arranged on its outer surface will move upward on the inner wall of the positioning groove 101.

[0039] Specific usage process: when it is necessary to use the grabbing device for LGA bottom cover installation, the shell 1 is installed at the end of the robot arm, and the LGA bottom cover to be installed is installed into the inner wall of the stacking plate 2, so that the LGA bottom cover to be installed is continuously stacked on the inner wall of the stacking plate 2. When it is necessary to install the motherboard, the shell 1 is moved by the robot arm and moved to the top surface of the object, and the three clamping claws 303 are at the same height of the object. When the object needs to be clamped and installed on the surface of the motherboard, the drive motor 405 is started. When the drive motor 405 is started, it will drive the transmission wheel 404 installed at its output end to rotate, and the outer surface of the transmission wheel 404 is installed with a transmission track 402. At this time, the rotating transmission wheel 404 will drive the transmission track 402 to rotate, and the transmission track 402 is at the outer surface of the ball slider 401 at the same time, so the rotating transmission The track 402 drives the ball slider 401 to rotate on the inner wall of the positioning bearing 4. When the ball slider 401 rotates on the inner wall of the positioning bearing 4, since the inner wall of the ball slider 401 rotates between the inner wall of the threaded groove 104, the driving tube 102 and the meshing teeth 105 set on its outer surface will move upward on the inner wall of the positioning groove 101, and the meshing teeth 105 are meshed with the gear 302. Therefore, when the screw drives the meshing teeth 105 to move upward, the gear 302 meshing with it will rotate on the inner wall of the rotating bearing 301, thereby driving the clamping claws 303 installed on the outer surface of the gear 302 to deflect, and finally making the three clamping claws 303 move inward and contact with each other to clamp the object, and then the object is driven by the clamping claws through the mechanical arm to move to the top surface of the mainboard, and the object is placed at the specified position of the mainboard to realize the assembly of the mainboard.

[0040] When the LGA bottom cover needs to be grabbed and installed, the driving motor 405 is used to control the driving tube 102 to retract toward the inner wall of the housing 1. When the driving tube 102 is completely retracted, the electric telescopic rod 202 is started. When the electric telescopic rod 202 is started, its end will extend to drive the moving plate 203 to move on the inner wall of the moving groove 201. A push plate 204 is installed on the top surface of the moving plate 203. When the push plate 204 moves with the moving plate 203, the push plate 204 will It moves from the outer side of the stacking plate 2 to its inner wall, and contacts with the LGA bottom covers stacked in the stacking plate 2 during the movement, thereby pushing the LGA bottom cover to move. At this time, the pushed LGA bottom cover will move along the surface of the stacking plate 2, and slide into the inner wall of the feed chute 108 during the movement. When the electric telescopic rod 202 is fully extended, the entire LGA bottom cover will be on the inner wall of the feed chute 108, which is convenient for the driving tube 102 to grab the LGA bottom cover later.

[0041] After the LGA bottom cover is moved, the air pipe 103 installed on the top surface of the driving tube 102 is connected to the air pump, and the air pump is started to generate negative pressure in the air pipe 103 and the driving tube 102. At this time, the driving motor 405 is controlled to start again to drive the driving tube 102 to move downward along the inner wall of the positioning groove 101, and the clamping claw 303 is opened upward by the mutual engagement between the meshing teeth 105 and the gear 302. As the driving tube 102 continues to move downward, the driving tube 10 2 will contact with the LGA bottom cover on the inner wall of the feeding chute 108. Since the suction cup 106 is installed on the bottom surface of the driving tube 102, and the inner wall of the driving tube 102 is in a negative pressure state at this time, the driving tube 102 will absorb and fix the LGA bottom cover by the negative pressure. Since the driving tube 102 is still moving downward at this time, the driving tube 102 will push the LGA bottom cover downward, so that the bottom surface of the LGA bottom cover contacts the blocking plate 106 installed on the inner wall of the setting plate 107. 9 is squeezed, and the blocking plate 109 will rotate 90 degrees on the inner wall of the setting plate 107 when being squeezed. After the blocking plate 109 rotates 90 degrees, it will no longer block the LGA bottom cover, so that the driving tube 102 can continue to drive the LGA bottom cover to move downward. As the driving tube 102 is continuously extended, the upward rotation angle of the clamping claw 303 will gradually increase. When the driving tube 102 is fully extended, the three clamping claws 303 will open upward due to the extension of the driving tube 102, so as to prevent the clamping claws 303 from contacting with other accessories installed on the motherboard when the driving tube 102 is installed on the LGA bottom cover, thereby causing damage to the accessories. After the driving tube 102 is fully extended, the housing 1 is driven by the mechanical arm to move to the specified position, so that the LGA bottom cover fixed at the bottom of the driving tube 102 is aligned with the installation position. After the alignment is completed, the negative pressure in the driving tube 102 is eliminated by controlling the air pump, so that the LGA bottom cover falls on the surface of the motherboard, thereby realizing the grabbing and installation of the LGA bottom cover.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
