detailed description

In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

As shown in Figure 1-2, a processing device for anti-theft buttons includes a support 1, a pressure operation module, a segmentation module and a control module arranged on the support. Specifically, the pressure operation module includes a magnetic pressing rod 21, a coil positioning die 22, and a pressing rod driver 23; Including signal receiver, detector and controller.

The turntable 31 can rotate by itself, and the turntable driving member is used to drive the turntable 31 to rotate. The pressure operation module is arranged above the turntable and fixed by a bracket. The pressure magnet rod 21 can move up and down above the workpiece. The position of the coil positioning die 22 is set on the turntable, and the position should be set so that when the turntable rotates to the stamping position, the coil positioning die 22 is just in front of the pressure magnet rod 21. Below, so that the coil positioning die 22 can cooperate with the magnetic pressing bar to stamp the workpiece. There are at least 4 coil positioning dies 22, and in this embodiment, the number of coil positioning dies 22 is set to 6, and these coil positioning dies 22 are distributed on the upper surface of the turntable at intervals along the circumferential direction of the turntable . In order to stamp the workpiece better, the coil positioning die 22 can be set in a step shape, so that it is difficult to pull out the magnetic rod after being pressed in, and it is not easy to separate from the workpiece during the stamping process, and the stamping effect is better. Product qualification rate increased. The pressing rod driver 23 is connected to the top of the magnetic pressing rod 21 , and the up and down movement of the magnetic pressing rod 21 is realized by the driving of the pressing rod driving member 23 to the magnetic pressing rod 21 . In this embodiment, the pressing rod driving member 23 is configured as an air cylinder.

Secondly, the turntable 31 is rotated under the drive of the turntable drive, and in this embodiment, the turntable drive is set as a rotating motor. The divider 32 and the position detection switch 33 are all arranged at the lower position of the turntable. The position detection switch 33 can receive and detect the pulse of the turntable. When the pulse arrives, the position detection switch 33 can control the turntable The driving part drives the turntable, so that the turntable rotates a station, the last completed workpiece is turned out, and the next unfinished workpiece is turned under the pressure magnetic rod. In order to detect the frequency of the workpiece in real time, so that the stamping operation can be stopped immediately when the frequency of the workpiece reaches the standard, an induction coil 34 can be installed at the position corresponding to the workpiece, and the frequency of the workpiece can be sensed in real time through the induction coil 34 . In order to facilitate the stamping operation of the workpiece, we arrange the induction coil 34 below the turntable 31, which will not affect the operation of the upper part, and the induction coil 34 will not be affected by the stamping force, is not easy to be damaged, and has a long service life. In order to ensure the accuracy of detection, the position of the induction coil 34 is set corresponding to the position of the coil positioning die 22 to sense the frequency of the workpiece in real time.

The signal receiver, detector and controller are all arranged under the turntable, the signal receiver is used to receive the signal sent by the induction coil 34 after sensing the frequency of the workpiece, and the detector is used to judge whether the frequency of the workpiece reaches the standard . The controller is used to control various mechanical operations to realize the complete automation of the equipment. The pressing bar driving part 23, the turntable driving part and the discharging driving part are all electrically connected to the controller. In this embodiment, the detector can be set as a microcomputer. When the signal transmitted by the induction coil is detected by the microcomputer and judged that the resonant frequency reaches the standard, the controller controls the pressure rod driver 23 to stop the downward drive of the pressure rod. , and at the same time control the turntable driving part to drive the turntable to rotate a station, and turn the qualified workpiece out of the bottom of the magnetic bar. If the detection still fails to meet the standard, the pressure magnetic rod will continue to be pressed down until the detection frequency is qualified. However, due to the limited pressing stroke of the pressing magnetic rod, in order to prevent the pressing magnetic rod from being damaged due to excessive downward pressure, we set an infrared detection switch on the bracket, which can be pressed to the bottom of the pressing magnetic rod 21. When the maximum position is reached, stop the depressing action of the magnetic bar 21, control the magnetic bar 21 to get back to the initial position, and then press down next time.

In order to realize the automatic operation of the equipment, save manpower and improve work efficiency. We also set up a feeding mechanism and a discharging mechanism on the equipment. Specifically, the feeding mechanism includes a vibrating plate 41 capable of vibrating feeding, and the vibrating plate 41 has a certain inclination angle. The lowest point of inclination of the vibration plate 41 is located directly above the turntable. The vibrating plate 41 is provided with a receiving groove for placing the workpiece. When the receiving groove drives the workpiece to rotate to the position above the turntable, the vibrating plate vibrates to make the workpiece fall from the containing groove onto the turntable, realizing automatic feeding without manual operation. The discharge mechanism includes a mechanical claw 51, a discharge drive, and an external hopper 52. The mechanical claw 51 can take out the finished workpiece from the turntable after the operation is completed, and then put it into the external hopper for accommodating the finished workpiece within 52. The discharge driving part is used to drive the mechanical claw to take the finished workpiece.

The specific operation is as follows:

The workpiece is transferred to the turntable by the feeding mechanism, and placed on the coil positioning mold, and then the turntable rotates a station, so that the workpiece rotates to the position below the magnetic rod; the pressure rod driver drives the magnetic rod to press down into the workpiece, At the same time, the induction coil senses the frequency of the workpiece in real time, and feeds the signal back to the controller; when the frequency signal received by the controller reaches a qualified value, it stops the pressing action of the magnetic rod, and controls the magnetic rod to return to the initial position ; Then the turntable rotates, the completed workpiece is turned out from under the magnetic bar, and the next unfinished workpiece is transferred to the bottom of the magnetic bar; the discharge mechanism takes out the completed workpiece and presses the magnetic bar for the next step. wheel punching operation.

Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
