[0002] Threaded plugs are sealing fasteners with a threaded structure. They achieve the sealing function of a pipeline system by being screwed into the external thread of the pipe end or a pre-drilled threaded hole in a mechanical component. Their core function is to prevent the leakage of liquid and gaseous media and ensure the integrity of the sealing system.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-6 The illustrated fully automatic threaded plug feeding and assembly equipment includes a base 1, on which a loading and unloading positioning component 2 and a robotic arm 3 are mounted. The loading and unloading positioning component 2 includes a translation mechanism 201, a positioning seat 202, a positioning block 203, and a clamping cylinder 204. The output end of the robotic arm 3 is fixedly connected to a screw locking mechanism 301. Multiple plug loading and turning mechanisms 4 and a bit loading and unloading mechanism 5 are mounted on the base 1 next to the loading and unloading positioning component 2. The plug loading and turning mechanism 4 includes a vibrating feeder 401, a rotary cylinder 402, and a first gripper cylinder 403. On the base 1, on both sides of the discharge end of the vibrating feeder 401, a misalignment cylinder 404 and a receiving box 405 are fixedly connected. The bit loading and unloading mechanism 5 includes an XY moving module 501, a second gripper cylinder 502, a limit claw 503, a lifting cylinder 504, a loosening cylinder 505, a pallet 506, and a bit 507.

[0023] The translation mechanism 201 drives the positioning seat 202 to perform translational sliding motion on the base 1. The base 1 guides the sliding of the positioning seat 202. The positioning block 203 and the clamping cylinder 204 are fixedly connected to the positioning seat 202. There are multiple clamping cylinders 204 on the positioning seat 202, and the multiple clamping cylinders 204 are evenly distributed on the positioning seat 202. The multiple clamping cylinders 204 can better achieve the clamping of the shell.

[0024] The vibratory feeder 401 can feed threaded plugs. The first gripper cylinder 403 is used to clamp the threaded plugs in the feeding position, and the rotary cylinder 402 is used to drive the clamped threaded plugs to change direction. A distance sensor 406 is fixedly connected to the discharge end of the vibrating feeder 401. The distance sensor 406 is used to detect whether there is a misalignment of the threaded plug (to detect whether the length of the threaded plug is correct). If a misalignment occurs, the extension and retraction of the piston rod of the misalignment cylinder 404 drives the threaded plug to the receiving box 405 for unloading. An elastic loading platform 407 is slidably connected to the slide of the misalignment cylinder 404. The elastic loading platform is provided with a clearance groove, which can make way for the flipping action of the first gripper cylinder 403. The elastic loading platform 407 is connected to the discharge end of the vibrating feeder 401. The discharge end of the vibrating feeder 401 is connected to the clearance groove for discharge. A spring is provided between the elastic loading platform 407 and the slide of the misalignment cylinder 404. The spring is used to reset the elastic loading platform 407.

[0025] The XY moving module 501, the lifting cylinder 504, and the loosening cylinder 505 are all fixedly connected to the base 1. The second gripper cylinder 502 is fixedly connected to the moving platform of the XY moving module 501. The limiting claw 503 is fixedly connected to the gripper of the second gripper cylinder 502. The support plate 506 is fixedly connected to the piston rod of the lifting cylinder 504. The loosening slide 508 is fixedly connected to the piston rod of the loosening cylinder 505.

[0026] The limiting claw 503 is provided with a V-shaped groove, which can limit and guide the bit rod 507 during installation. The support plate 506 is provided with a positioning groove, which is used to position and place the bit rod 507. The lower end of the bit rod 507 is located in the positioning groove, and the bit rod 507 is located between the V-shaped grooves of the two limiting claws 503.

[0027] The working principle of this utility model is as follows: During the assembly and processing of the shell, the shell is placed on the positioning seat 202 along the positioning block 203. Then, the shell is pressed by the clamping cylinder 204. Subsequently, the translation mechanism 201 drives the positioning seat 202 to slide to the processing station. There are multiple plug feeding and turning mechanisms on the machine base. The diameter of the threaded plugs fed by different plug feeding and turning mechanisms is different. Before the threaded plug is installed, the robot arm 3 moves to the screw bar loading and unloading mechanism 5 to install the screw bar of the corresponding diameter. When the robot arm 3 drives the screw locking mechanism 301 to move directly above the screw bar of the corresponding diameter, the piston rod of the loosening cylinder 505 extends, the lifting slide 508 rises, and the elastic clamp at the end of the screw locking mechanism 301 used to clamp the screw bar 507 puts it in a loosening state. At this time, the piston rod of the lifting cylinder 504 is lifted. Extending, the support plate 506 lifts the bit rod 507 up and inserts it into the elastic clamp of the screw fastening mechanism 301. At this time, the piston rod of the release cylinder 505 retracts, and the bit rod 507 is clamped by the elastic clamp. Then, the limiting claw 503 of the second gripper cylinder 502 opens, and the robot arm 3 drives the bit rod 507 to move to the plug feeding and flipping mechanism 4. After the threaded plug is fed by the vibrating feeder 401, it is clamped by the first gripper cylinder 403 and rotated 180° by the rotary cylinder 402 to complete the flipping. After flipping, the hexagonal hole of the threaded plug faces upward. The robot arm 3 and the screw fastening mechanism 301 drive the bit rod 507 to rotate and descend, so that it is inserted into the hexagonal hole of the threaded plug. The threaded plug is then transferred to the housing for installation by the magnetic adsorption of the bit rod 507. The bit rod 507 can be used to replace the bit rod 507 for installation of other diameter threaded plugs in the same way.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
