[0018] 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.

[0019] Please see Figures 1 to 3 This utility model provides a technical solution: a transmission limiting component for a circulating feeder, including a feeder body 1, a robotic arm 3 on the top surface of the feeder body 1, a pneumatic gripper 4 at the end of the robotic arm 3, and several sensors on the robotic arm 3 for identifying the required data such as the position and thickness of the blank.

[0020] The lower end of the robotic arm 3 is provided with a circular track 2, and the circular track 2 is provided with a number of limiting installation mechanisms for installing blanks. There are twelve sets of limiting installation mechanisms.

[0021] The limiting installation mechanism includes a mounting base plate 5, which is fixedly installed on the conveyor belt on the circular track 2. A fixing clamping block 6 is provided on each adjacent side of the upper surface of the mounting base plate 5, and an installation block 7 is provided on the opposite side of each fixing clamping block 6. The fixing clamping block 6 and the installation block 7 form a placement groove on the upper surface of the mounting base plate 5, and the blank is installed in the placement groove.

[0022] The mounting block 7 is equipped with an adjustable fixing assembly, which includes an inner movable block 8 movably disposed inside the mounting block 7. Two top posts 9 are provided on one side of the inner movable block 8, passing through the side wall of the mounting block 7. The top posts 9 are used to abut against the side of the blank material for fixing. A push spring 10 is provided between the two top posts 9, located between the inner movable block 8 and the inner wall of the mounting block 7. A first airbag 11 is provided on the other side of the inner movable block 8. A rotating shaft 13 is provided next to the inner movable block 8. A bottom cylinder 17 is provided inside the mounting block 7. The bottom cylinder 17 is only partially inside the mounting block 7. It can move longitudinally. The bottom of the bottom cylinder 17 is connected to a clamping spring 18. The top surface of the bottom cylinder 17 is provided with a threaded hole. The lower end of the rotating shaft 13 is threaded and inserted into the bottom cylinder 17 and connected with the threaded hole. The middle of the rotating shaft 13 is rotatably sleeved with a lifting plate 14. The upper surface of the lifting plate 14 is provided with a second airbag 15. The supporting force of the second airbag 15 itself will not be compressed by the clamping spring 18. The second airbag 15 and the first airbag 11 are connected through a connecting pipe 16. The top of the second airbag 15 is fixed to the inner top surface of the mounting block 7. The top of the rotating shaft 13 passes through the round hole on the top surface of the mounting block 7 and is connected to a knob 12.

[0023] In actual use, twelve CNC blanks are manually loaded onto the circular track 2, and then moved at a constant speed by the conveyor belt to the displacement sensors. A set of displacement sensors at the front end of the robotic arm 3 identifies the width of the blanks, and a set of displacement sensors above the robotic arm 3 identifies the thickness of the blanks. After automatically identifying the blank thickness, the equipment transmits the measurement data to the pneumatic caliper of the lathe. At this time, the CNC door opens, and the robotic arm automatically delivers the measured blanks to the pneumatic caliper. The pneumatic caliper automatically opens and clamps the blanks according to the transmitted data. Simultaneously, the robotic arm retracts... Once the CNC machine is finished, the CNC door closes to process the blank. The CNC machine automatically identifies and grabs the next blank. After CNC processing, the CNC door opens, and the robotic arm 3 descends to remove the finished CNC product. At the same time, air is blown out from the nozzle to remove burrs, and the data of the blank grabbed in the previous step is transmitted to the pneumatic caliper. The blank is placed into the pneumatic caliper, the CNC door closes, the robotic arm 3 places the finished CNC product into the qualified product area, and grabs the next CNC blank. The equipment operates continuously, repeating the cycle, which can effectively solve the problem of long-term manual supervision in front of the CNC machine.

[0024] When manually loading the front end, the blank is placed in the placement slot. Rotating the knob 12 causes the rotating shaft 13 to drive the lifting plate 14 to rise. The second airbag 15 is compressed, allowing the gas inside to enter the first airbag 11. The first airbag 11 expands and pushes the inner movable block 8 and the top column 9, thereby causing the top column 9 to extend and tighten the blank. When the robotic arm 3 picks up the part, the pneumatic gripper 4 is equipped with a pin corresponding to the knob 12. The pin presses down the knob 12, causing the bottom cylinder 17 to descend and the clamping spring 18 to compress, thereby stretching the second airbag 15. The gas inside the first airbag 11 enters the second airbag 15. The push spring 10 can push the inner movable block 8, thereby causing the top column 9 to retract. At this time, the blank is released, making it easier for the pneumatic gripper 4 to pick up the part.
