During use, an external machine tool transports the screws to the loading area, and the screws fall into the clamping and positioning mechanism 6 through the loading mechanism 3. The clamping and positioning mechanism 6 is pushed to the bottom of the material removal area by pushing the driving mechanism 4, and then an external tightening gun is used to remove the screws in the clamping and positioning mechanism 6.

[0026] The sliding mechanism 5 comprises a slide rail 51, a slider 52, and a sliding seat 53. The slide rail 51 is mounted on the base 1, and the slider 52 is slidably connected to the slide rail 51. The slider 52 is connected to the sliding seat 53 above the slider 52. The sliding seat 53 is equipped with a clamping and positioning mechanism 6. A connecting assembly is provided on the end of the sliding seat 53 near the push drive mechanism 4; the output end of the push drive mechanism 4 is connected to the connecting assembly. The slide rail 51 guides the slider 52, which drives the sliding seat 53 to the material removal area. The clamping and positioning mechanism 6 is then pushed to the material removal area via the slider 52 in coordination with the push drive mechanism 4, completing the screw removal process.

[0027] The clamping positioning mechanism 6 comprises a clamping cylinder 61 and clamping arms 62. The clamping cylinder 61 is installed on the sliding seat 53, and the clamping arms 62 are installed on the clamping cylinder 61. The clamping cylinder 61 drives the clamping arms 62 to open and close. The clamping arms 62 are at least three. All the clamping arms 62 form a clamping area. When the screw falls from the feeding mechanism 3 to the clamping area, the clamping cylinder 61 drives the clamping arms 62 to clamp the screw.

[0028] The sliding seat 53 is fixed with a positioning arm 531. The positioning arm 531 is provided with a positioning hole 532. The positioning hole 532 positions the top of the screw. The positioning arm 531 is above all the clamping arms 62, and the positioning hole 532 is aligned with the clamping area. The positioning hole 532 is used to determine whether the screw moves to a specific position of the taking area.

[0031] The base 1 is provided with a buffer mechanism 7. The buffer mechanism 7 is located on the side of the sliding seat 53 away from the pushing driving mechanism 4. The buffer mechanism 7 comprises a support 71, a buffer rod 72, a buffer rubber head 73, a anti-loose nut 74 and a buffer spring. The support 71 is fixed with the base 1.

The support 71 is arranged between the buffer rubber head 73 and the anti-loose nut 74. The buffer rod 72 penetrates through the buffer spring. The buffer spring is located between the buffer rubber head 73 and the support 71. When the pushing driving mechanism 4 pushes the sliding seat 53 to the taking area, the sliding seat 53 is blocked by the buffer rubber head 73. The buffer spring elastically supports the buffer rod 72. The buffer rubber head 73 generates a buffer force on the sliding seat 53. The sliding seat 53 can accurately move to the taking area. The top of the screw is aligned with the positioning hole 532. The anti-loose nut fixes the sliding seat 53 relative to the support 71, so as to avoid the deviation of the screw during taking.

[0032] The fixed frame 2 is provided with a sensing mechanism 8, which comprises a fixed support 81 and a pair of infrared sensors 82. The fixed support 81 is L-shaped, and is fixed to the side of the fixed frame 2 by bolts. The fixed support 81 is provided with the pair of infrared sensors 82. The fixed support 81 and the pair of infrared sensors 82 are each provided with four infrared sensors. Two of the infrared sensors form a group. The infrared of one group of infrared sensors can pass through the clamping area, and the infrared of the other group of infrared sensors can pass through the material taking area. The pair of infrared sensors are used to detect whether the clamping area or the material taking area is clamped with a screw. When the screw is in the clamping area, the infrared sensors of the clamping area detect the screw, and the pushing driving mechanism 4 is started to push the sliding seat 53 to the material taking area. Meanwhile, the infrared sensors of the material taking area detect the screw, and the external tightening gun is started to take the screw.

[0033] The fixed frame 2 is provided with a sensing mechanism 8, which comprises a fixed support 81 and a pair of infrared sensors 82.

The fixed support 81 and the pair of infrared sensors 82 are each provided with four infrared sensors. Two of the infrared sensors form a group. The infrared of one group of infrared sensors can pass through the clamping area, and the infrared of the other group of infrared sensors can pass through the material taking area. The pair of infrared sensors are used to detect whether the clamping area or the material taking area is clamped with a screw. When the screw is in the clamping area, the infrared sensors of the clamping area detect the screw, and the pushing driving mechanism 4 is started to push the sliding seat 53 to the material taking area. Meanwhile, the infrared sensors of the material taking area detect the screw, and the external tightening gun is started to take the screw.
