Description

Technical Field

[0001] This utility model relates to the field of anchor bolt production technology, and in particular to an automatic installation device for anchor bolt thread protective sleeves. Background Technology

[0002] Metal anchor bolts are manufactured using left-hand threaded steel through processes such as cutting, necking, and thread rolling. During transportation and handling, the bolts may collide with each other, and external impacts can damage the threads formed during the thread rolling process, directly affecting the anchor bolt's pull-out performance. Therefore, to protect the anchor bolts, plastic (but not limited to) protective sleeves must be installed at the threads after machining to protect the bolt threads.

[0003] In traditional techniques, the installation of threaded protective sleeves is a manual operation. During production, personnel stand at the rear end of the thread rolling process, select the matching plastic protective sleeve, and manually install it onto the rod thread. This manual installation method is time-consuming and labor-intensive, requiring personnel to stand for extended periods and posing risks such as finger injuries from being scratched or pinched by the threads. Therefore, this invention proposes an automated installation device for anchor bolt threaded protective sleeves to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an automatic installation device for anchor bolt threaded protective sleeves. A sleeve-screening vibratory feeder automatically sorts and oriented the plastic sleeves. A cross-shaped turning mechanism transfers the plastic sleeves one by one to a six-axis robot, where the robot uses pneumatic fingers to grasp them. When the anchor bolt reaches a fixed area, an anchor bolt pusher mechanism pushes the anchor bolt onto an anchor bolt positioning rotary table mechanism. The anchor bolt then aligns with the plastic sleeve grasped by the pneumatic fingers on the anchor bolt positioning rotary table mechanism, completing the automatic installation of the plastic sleeve using the pneumatic fingers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic installation device for anchor bolt threaded protective sleeves includes an equipment frame, a sleeve screening vibratory feeder, a cross-shaped turning mechanism, and an anchor bolt positioning rotary table mechanism. A vibratory feeder mounting base is located on one side of the equipment frame, on which the sleeve screening vibratory feeder is mounted. A sleeve pushing direct vibration mechanism is located on one side of the outlet of the sleeve screening vibratory feeder. A cross-shaped turning mechanism is located on the equipment frame, next to the sleeve pushing direct vibration mechanism. A six-axis robot is located in front of the cross-shaped turning mechanism, and the six-axis robot is equipped with pneumatic fingers. An anchor bolt pusher mechanism is located at the top of the equipment frame, and an anchor bolt positioning rotary table mechanism is located on one side of the anchor bolt pusher mechanism.

[0006] A further improvement is that: the vibratory feeder mounting base is provided with a mounting bracket, the mounting bracket is provided with a photoelectric switch sensor, and the photoelectric switch sensor is electrically connected to the sheath screening vibratory feeder.

[0007] A further improvement is that the cross-shaped material turning mechanism includes a stand, a first servo motor, and positioning rods. The stand is equipped with the first servo motor, and four sets of positioning rods are equidistantly arranged on the outer wall of the output end of the first servo motor.

[0008] A further improvement is that the anchor bolt pusher mechanism includes a pusher cylinder and a pusher platform, the pusher platform is located at the output end of the anchor bolt chain transmission conveyor mechanism, and the pusher cylinder is located on top of the pusher platform.

[0009] A further improvement is that: the top of the push rod platform is provided with a guide groove, and a push block is movably disposed in the guide groove, and the output end of the push rod cylinder is connected to the push block.

[0010] A further improvement is made in that: the anchor bolt positioning rotary disk mechanism includes a first rotary disk assembly and a second rotary disk assembly. The second rotary disk assembly is provided on one side of the first rotary disk assembly. The first rotary disk assembly and the second rotary disk assembly have the same structure, both including an assembly frame, a disk body, a groove, and a hook baffle. A second servo motor is provided on the assembly frame. The output end of the second servo motor is provided with the disk body. The edge of the disk body is provided with a groove. There are eight sets of grooves. The outer wall of the disk body is provided with a hook baffle. The number of hook baffles is adapted to the grooves, and the hook baffles are located on one side of the grooves.

[0011] The beneficial effects of this utility model are as follows: The equipment of this utility model automatically sorts and arranges plastic sheaths by means of a sheath screening vibrating plate. The cross-shaped turning mechanism transfers the plastic sheaths one by one to the six-axis robot, which then uses pneumatic fingers to grab the plastic sheaths. When the anchor rod moves to the fixed area, the anchor rod pusher mechanism pushes the anchor rod onto the anchor rod positioning rotating plate mechanism. Then the anchor rod is aligned with the plastic sheath grabbed by the pneumatic fingers on the anchor rod positioning rotating plate mechanism, and the automatic installation of the plastic sheath is completed by the pneumatic fingers. This utility model equipment realizes the fully automated installation of anchor bolt thread plastic sleeves, which can improve the installation efficiency of plastic sleeves, reduce manual input and safety hazards during the process.

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1-4 As shown, this embodiment proposes an automatic installation device for anchor bolt thread protective sleeves, including a device frame 1, a protective sleeve screening vibratory plate 2, a cross-shaped material turning mechanism 3, and an anchor bolt positioning rotary plate mechanism 4. A vibratory plate mounting base 5 is provided on one side of the device frame 1, and the protective sleeve screening vibratory plate 2 is mounted on the vibratory plate mounting base 5. A protective sleeve pushing direct vibration mechanism 6 is provided on one side of the outlet of the protective sleeve screening vibratory plate 2. The cross-shaped material turning mechanism 3 is located on one side of the protective sleeve pushing direct vibration mechanism 6. A six-axis robot 7 is provided in front of the cross-shaped material turning mechanism 3, and pneumatic fingers 8 are provided on the six-axis robot 7. An anchor bolt push rod mechanism 9 is provided at the top of the device frame 1, and the anchor bolt positioning rotary plate mechanism 4 is provided on one side of the anchor bolt push rod mechanism 9.

[0016] In use, the automatic installation equipment for anchor bolt thread protective sleeves of this utility model involves placing 80-100 plastic sleeves in batches into the sleeve screening vibratory plate 2. The plastic sleeves are vibrated and rotated within the vibratory plate 2, entering a spiral track. A notch 1.5 times the length of the plastic sleeve is provided in the middle of the spiral track, with a screening stop at the notch. When the open end of the plastic sleeve faces forward, it can pass smoothly through the notch; when the open end faces backward, the weight difference between the two ends causes the sleeve to fall from the notch to the bottom of the vibratory plate for the next screening cycle. Plastic sleeves with the correct opening orientation enter the sleeve pushing linear vibration mechanism 6. In this utility model, the sleeve pushing linear vibration mechanism 6 is existing technology, used for buffering, vibration, stopping, and pushing directional sorting. The plastic sheath is fed to the cross-shaped turning mechanism 3, and then the six-axis robot 7 uses its pneumatic fingers 8 on its sixth axis to grab the plastic sheath from the cross-shaped turning mechanism 3 and move it to the designated position. At this time, the anchor rod conveyed by the anchor rod chain drive conveyor reaches the anchor rod pusher mechanism 9 and is pushed by the anchor rod pusher mechanism 9 to the anchor rod positioning rotary disk mechanism 4. When the anchor rod positioning rotary disk mechanism 4 rotates, it rotates the anchor rod positioned on it to align with the plastic sheath grabbed by the pneumatic fingers 8. The pneumatic fingers 8 put the plastic sheath on the anchor rod and reset it to the next cycle position. The anchor rod with the plastic sheath installed is still positioned on the anchor rod positioning rotary disk mechanism 4. The anchor rod positioning rotary disk mechanism 4 continues to rotate to realize the unloading of the anchor rod onto the anchor rod chain drive conveyor at the designated position for discharge.

[0017] The vibratory feeder mounting base 5 is equipped with a mounting bracket 10, and the mounting bracket 10 is equipped with a photoelectric switch sensor 11, which is electrically connected to the sheath screening vibratory feeder 2. In this invention, the photoelectric switch sensor 11 is used to control the start and stop of the sheath screening vibratory feeder 2. When the number of automatically oriented and sorted plastic sheaths entering the sheath pushing vertical vibration mechanism 6 reaches the set maximum value, the photoelectric switch sensor 11 sends a signal to the PLC program of the equipment, and the sheath screening vibratory feeder 2 stops running; when the number of plastic sheaths in the sheath pushing vertical vibration mechanism 6 does not reach the set minimum value, the photoelectric switch sensor 11 feeds back a signal to the PLC program of the equipment, controlling the sheath screening vibratory feeder 2 to start and continuously feed materials to the sheath pushing vertical vibration mechanism 6.

[0018] The cross-shaped flipping mechanism 3 includes a stand 301, a first servo motor 302, and positioning rods 303. The first servo motor 302 is mounted on the stand 301, and four sets of positioning rods 303 are equidistantly arranged on the outer wall of the output end of the first servo motor 302. The plastic sheaths sorted and oriented by the sheath screening vibratory plate 2 are temporarily buffered in the sheath pushing linear vibration mechanism 6. The foremost plastic sheath is stopped at the push position by the pneumatic gate in the sheath pushing linear vibration mechanism 6. When the positioning rod 303 of the cross-shaped flipping mechanism 3 flips to the front end of the plastic sheath, the photoelectric switch detects the signal and controls the solenoid valve to open the exhaust valve and the pneumatic gate respectively. Compressed air pushes the foremost sheath onto the positioning rod 303 of the cross-shaped flipping mechanism 3. The pneumatic gate opens and closes instantly, stopping the second sheath and preparing for the next push.

[0019] The anchor bolt pusher mechanism 9 includes a pusher cylinder 901 and a pusher platform 902. The pusher platform 902 is located at the output end of the anchor bolt chain drive conveying mechanism, and the pusher cylinder 901 is mounted on top of the pusher platform 902. A guide groove 903 is provided on the top of the pusher platform 902, and a pusher block 904 is movably mounted within the guide groove 903. The output end of the pusher cylinder 901 is connected to the pusher block 904. The anchor bolt conveyed by the anchor bolt chain drive conveying mechanism enters the guide groove 903 and is positioned. Then, the pusher platform 902 extends, driving the pusher block 904 to push the anchor bolt onto the anchor bolt positioning rotary disk mechanism 4.

[0020] The anchor bolt positioning rotary disk mechanism 4 includes a first rotary disk assembly 401 and a second rotary disk assembly 402. The second rotary disk assembly 402 is provided on one side of the first rotary disk assembly 401. The first rotary disk assembly 401 and the second rotary disk assembly 402 have the same structure, both including an assembly frame 12, a disk body 13, a groove 14 and a hook baffle 15. A second servo motor 16 is provided on the assembly frame 12. The output end of the second servo motor 16 is provided with the disk body 13. The edge of the disk body 13 is provided with grooves 14, and there are eight sets of grooves 14. The outer wall of the disk body 13 is provided with hook baffles 15. The number of hook baffles 15 is adapted to the grooves 14, and the hook baffles 15 are located on one side of the grooves 14. When the anchor rod enters the anchor rod positioning rotary disk mechanism 4, it is supported by the grooves 14 of the first rotary disk assembly 401 and the second rotary disk assembly 402, and positioned by the hook baffle 15. The first rotary disk assembly 401 and the second rotary disk assembly 402 rotate synchronously (two second servo motors 16 are controlled by the same controller), so as to continuously flip the anchor rod to the position of the pneumatic finger 8 for automatic insertion of the plastic sheath.

[0021] This invention utilizes a vibratory feeder 2 to automatically sort and oriented plastic sheaths. A cross-shaped turning mechanism 3 transfers each plastic sheath to a six-axis robot 7, where the robot uses pneumatic fingers 8 to grasp them. When the anchor rod reaches a fixed area, an anchor rod pusher mechanism 9 pushes the anchor rod onto an anchor rod positioning rotary table mechanism 4. The anchor rod then aligns with the plastic sheath grasped by the pneumatic fingers 8 on the anchor rod positioning rotary table mechanism 4, completing the automatic installation of the plastic sheath. This invention achieves fully automated installation of anchor rod threaded plastic sheaths, improving installation efficiency while reducing manual labor and safety hazards.
