The moving block 7 is slidably connected in the straight groove 8. A linear actuator 9 is installed on the rack 1. The linear actuator 9 can be an electric cylinder. The output end of the linear actuator 9 is cooperatively arranged with the moving block 7. A rotary driving device 10 is installed on the rack 1. The rotary driving device 10 can be a servo motor. A bidirectional screw rod 11 is rotatably installed on the rack 1. The output end of the rotary driving device 10 is in transmission connection with the bidirectional screw rod 11. The two moving frames 4 are in threaded connection with the bidirectional screw rod 11. The linear actuator 9 and the rotary driving device 10 are in signal connection through a signal processor.

[0022] In the embodiment, the top end of the rack 1 is connected with the mechanical arm, the rack 1 is moved to the end of the conveying line 2 by the mechanical arm, so that the two moving racks 4 can be located on both sides of the anchor rod 3 on the conveying line 2, then the linear actuator 9 is started to be elongated, so as to extrude the two moving blocks 7 to slide in the straight groove 8 to both sides, so that the moving block 7 can drive the cylinder 6 to slide to the edge position of the V-shaped groove 5 on both sides, at this time, the positions of the corresponding two cylinders 6 on the symmetric moving racks 4 correspond to the positions of the regular polygon end head of the anchor rod 3 in the normal or upside-down state, then the rotary driving device 10 is started, the two-way threaded rod 11 is driven to rotate by the rotary driving device 10, so that the two moving racks 4 can be moved oppositely, so that the cylinder 6 on the moving rack 4 can clamp and fix the regular polygon end head of the anchor rod 3, when the moving racks 4 move oppositely, the linear actuator 9 is elongated, so that the cylinder 6 can always be located at the position on both sides of the V-shaped groove 5, after the cylinder 6 clamps the end head of the anchor rod 3, the linear actuator 9 is retracted, the rack 1 is raised by the mechanical arm, so that under the influence of gravity, the cylinder 6 and the moving block 7 can slide to the bottom of the V-shaped groove 5, and the gravity of the anchor rod 3 is relatively large, so that the cylinder 6 clamping the anchor rod 3 can extrude the cylinder 6 on the other side which is not clamped, so that the clamped cylinder 6 can be located at the lowest end of the V-shaped groove 5, and through the rotary connection of the cylinder 6 and the moving block 7, the cylinder 6 clamps one side of the end head of the anchor rod 3, so that the anchor rod 3 can be vertically placed under the influence of its own gravity, so that the rack 1 can drive the anchor rod 3 in the vertical state to move to the subsequent assembly equipment, after the anchor rod 3 is inserted into the subsequent anchor rod sleeve assembly, the rotary driving device 10 controls the two-way threaded rod 11 to loosen the anchor rod 3.

[0023] In some embodiments, in order to facilitate clamping of the anchor rod 3, the conveying line 2 is provided with an entry groove 12 on both sides. The length of the entry groove 12 is matched with the moving rack 4, so that the moving rack 4 can enter the entry groove 12 to clamp the anchor rod 3.

The support block 13 is located at the end of the conveying line 2 to support the anchor rod 3, so that the length of the entry groove 12 is only slightly longer than the anchor rod 3, so that under the extrusion of the subsequent anchor rod 3, the anchor rod 3 is prevented from sliding out of the relatively long entry groove 12, and the moving rack 4 is prevented from colliding with the end of the conveying line 2.

[0025] In some embodiments, in order to facilitate extrusion of the two symmetrically arranged cylinders 6 by the linear actuator 9, the output end of the linear actuator 9 is provided with a V-shaped block 14, and the V-shaped block 14 is matched with the moving block 7.

[0026] In some embodiments, to avoid the impact of the rack 1 on the anchor rod 3 when the anchor rod 3 is moved out, a plurality of rollers 15 are arranged on the conveying line 2. The width of the conveying line 2 is matched with the size of the anchor rod 3, so that the rollers 15 can press the anchor rod 3.

[0027] In some embodiments, to facilitate the selection and manufacture of the cylinder 6 and the moving block 7, the cylinder 6 and the moving block 7 are preferably made of rigid polyvinyl chloride material.

[0028] In some embodiments, to enable the cylinder 6 and the moving block 7 to slide to the lowest end of the V-shaped groove 5 under the influence of the gravity of the anchor rod 3, a sliding block 16 is arranged at the bottom of the moving block 7, the sliding block 16 is slidingly connected in the straight groove 8, and the sliding block 16 is located outside the moving block 7.
