[0021] like Figure 1-4 As shown, this utility model provides a hardware parts clamping and feeding device, including a vibratory feeder 2, a limiting component 7, and a clamping component 8. The vibratory feeder 2 is mounted on a base plate 1, and its output slot 21 end is provided with a guide tube 3. The top of the discharge end of the guide tube 3 is provided with an opening 31. A cylinder 5 is mounted on a bracket 4 of the base plate 1, and the piston rod end of the cylinder 5 is connected to a fixing plate 6 through a connecting plate 51.

[0022] It should be noted that the limiting component 7 is mounted on the bracket 4 and is used to limit the output hardware 9. The limiting component 7 includes a second cylinder 71, a lifting plate 72, and a pressure sensor 73. The cylinder body of the second cylinder 71 is mounted on a fixed seat on the side of the bracket 4, and the lifting plate 72 is mounted on its piston rod. The lifting plate 72 has an "L" shape and is slidably connected to the cylinder body of the second cylinder 71, thereby improving the stability of the lifting plate 72. The pressure sensor 73 is mounted on the limiting block 74 at the top of the lifting plate 72 and faces the guide tube 3. The limiting block 74 has a "T" shape. The pressure sensor 73 is electrically connected to the controller. The pressure sensor 73 transmits the trigger signal of the hardware 9 to the controller, so that the controller can perform the next operation.

[0023] In addition, the clamping assembly 8 is disposed on the fixed plate 6 and is used to clamp and feed the hardware 9. The clamping assembly 8 includes a finger cylinder 81 and a clamping plate 82. The cylinder body of the finger cylinder 81 is installed on the side of the fixed plate 6. Each claw of the finger cylinder 81 is equipped with a clamping plate 82. The clamping plate 82 has a "Z" shaped structure and its inner side is provided with a clamping groove 821 for clamping the hardware 9.

[0024] In addition, the bracket 4 has an "L" shaped structure and a reinforcing plate 41 on its side, thereby strengthening the bracket 4.

[0025] Detailed implementation methods and principles:

[0026] During operation, the piston rod of cylinder 2 71 extends, causing the lifting plate 72 to move upward, so that the pressure sensor 73 in the limit block 74 faces the guide tube 3. The hardware parts 9 to be loaded are arranged in an orderly manner under the action of the vibrating plate 2 and enter the guide tube 3 through the output groove 21. When the hardware part 9 at the opening 31 of the guide tube 3 contacts the receiving end of the pressure sensor 73, the pressure sensor 73 will send a trigger signal to the controller. The controller will control the pneumatic gripper of the finger cylinder 81 to drive the clamping plate 82 to clamp the hardware part 9 at that location.

[0027] Next, the piston rod of the second control cylinder 71 retracts, thereby driving the lifting plate 72 and the limit block 74 to move down, at which point the vibrating plate 2 stops;

[0028] Then, the piston rod of cylinder 5 extends, driving the finger cylinder 81 on the fixed plate 6 to move, thereby moving the hardware 9 on the finger cylinder 81 to the loading position. Then, the gripper of the finger cylinder 81 is controlled to open, so that the clamping plate 82 releases the hardware 9.

[0029] Next, the piston rod of control cylinder 5 retracts, causing the finger cylinder 81 on the fixed plate 6 to reset, and the piston rod of control cylinder 71 extends, thereby causing the lifting plate 72 and the limit block 74 to move upward and reset. At this time, the vibratory plate 2 continues to work, conveying the next hardware part 9.

[0030] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
