DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] For example, see Figure 1-4 A mechanical arm with a disassembly function comprises a base plate 1 and a mechanical arm body 6. A fixed plate 2 is fixedly connected to the top of the base plate 1. A motor 3 is arranged on the side of the fixed plate 2. The motor 3 is connected to a threaded rod 4 through its output shaft. A moving seat 5 is slidably connected to the top of the base plate 1. The moving seat 5 is threadedly connected to the threaded rod 4. A quick installation and disassembly mechanism 7 is arranged at the bottom of the mechanical arm body 6. The quick installation and disassembly mechanism 7 comprises two installation grooves 71, an installation plate 73 and an air pressure chamber 76. The two installation grooves 71 are both arranged on the top of the moving seat 5. The insides of the two mounting grooves 71 are slidably connected with slide plates 72 through compression springs. The mounting plate 73 is fixedly connected to the bottom of the mechanical arm body 6. The bottom of the mounting plate 73 is fixedly connected to two plug blocks 74. The two plug blocks 74 are respectively in the two mounting grooves 71 in the initial state. The compression springs in the two mounting grooves 71 are in a taut state in the initial state. When the compression springs rebound, the two slide plates 72 will move upward. The upward movement of the two slide plates 72 drives the two plug blocks 74 to move upward, thereby driving the mounting plate 73 to separate from the moving seat 5. A slot 75 is provided on the side close to each plug block 74, and the air pressure chamber 76 is fixedly connected to the inner cavity of the moving seat 5. The left and right ends of the air pressure chamber 76 are both connected to push rods 77 in a piston sliding manner. A groove 78 is provided on the side away from the two push rods 77. The insides of the two grooves 78 are both connected to arc blocks 79 in a sliding manner through telescopic springs. The size of the slot 75 opening is equal to the size of the slot 78 opening. The two arc blocks 79 are respectively in the two slots 75 in the initial state. The two arc blocks 79 are respectively stuck in the two slots 75 so that the two The plug block 74 cannot move upward to separate the mounting plate 73 from the movable seat 5. The depth of the groove 78 is greater than the length of the arc block 79. The arc surfaces of the two arc blocks 79 are both facing upward. The arc block 79 can be completely retracted into the groove 78. When the arc surface of the arc block 79 is squeezed, it will move into the groove 78. The front end internal piston of the pneumatic chamber 76 is slidably connected to a pull rod 710. The end of the pull rod 710 away from the pneumatic chamber 76 is fixedly connected to a pull plate 711. A return spring is arranged on the surface of the pull rod 710. The bottom of the two slides 72 are both provided with a deceleration mechanism 8.

[0021] When in use, the motor 3 is turned on, and the motor 3 drives the threaded rod 4 to rotate through its output shaft, and the rotation of the threaded rod 4 drives the moving seat 5 to move, thereby driving the mechanical arm body 6 to move. When the mechanical arm body 6 needs to be removed from the moving seat 5, the pull rod 710 is pulled outward through the pull plate 711, and the reset spring is stretched. At this time, the air pressure in the air pressure chamber 76 will drive the push rods 77 at both ends to move into the air pressure chamber 76. The push rods 77 at both ends move into the air pressure chamber 76 and drive the two arc blocks 79 to leave the slot 75. At this time, the two plug blocks 74 lose the restriction of the arc block 79, and the compression spring will rebound and drive the two slide plates 72 to move upward. The two slide plates 72 move upward and drive the two plug blocks 74 to move upward, thereby driving the mounting plate 73 to separate from the moving seat 5. , completing the disassembly of the robot arm body 6, then the pull rod 710 is restored under the action of the reset spring, and the push rods 77 at both ends are also restored. When it needs to be reinstalled, the two plug blocks 74 are aligned with the two mounting grooves 71 and inserted. The two plug blocks 74 drive the two slide plates 72 to move downward, and the compression springs are gradually tightened. The two plug blocks 74 move downward and squeeze the arc surfaces of the two arc blocks 79. When the arc surfaces of the arc blocks 79 are squeezed, they move into the grooves 78, and the telescopic springs are tightened. When the grooves 78 fit the card slots 75, the telescopic springs rebound and drive the arc blocks 79 to be stuck in the card slots 75. The two arc blocks 79 are respectively stuck in the two card slots 75, so that the two plug blocks 74 cannot move upward, so that the mounting plate 73 is separated from the moving seat 5, and the installation is completed.

[0022] For example 2, please refer to Figure 1-5 On the basis of the first embodiment, the deceleration mechanism 8 includes a vertical plate 81 and deceleration particles 84. The vertical plate 81 is fixedly connected to the bottom of the slide plate 72. The side of the vertical plate 81 is hinged with a contact rod 83 through a hinge block 82. The deceleration particles 84 are fixedly connected to the inner wall of the mounting groove 71. The contact rod 83 is close to the deceleration particles 84, and the material of the deceleration particles 84 is rubber. When the vertical plate 81 moves with the slide plate 72, it will drive the contact rod 83 to contact the deceleration particles 84. When the contact rod 83 and the rubber deceleration particles 84 are squeezed, resistance will be generated.

[0023] When in use, based on the first embodiment, when the vertical plate 81 follows the slide plate 72 to move downward, it will drive the contact rod 83 to contact and deflect with the deceleration particles 84 without generating too much resistance. When the compression spring rebounds and drives the slide plate 72 to move upward, the vertical plate 81 drives the contact rod 83 to move upward and contact with the deceleration particles 84. It cannot deflect and will be squeezed with the deceleration particles 84. The contact rod 83 is squeezed with the rubber deceleration particles 84 and generates resistance to slow down the speed at which the slide plate 72 bounces upward, thereby preventing the robot arm body 6 from bouncing up too fast and the moving seat 5 from falling off and being damaged.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
