With customers' requirements for high quality of ferrite magnetic cores, the requirements for weight accuracy of ferrite magnetic cores are getting higher and higher, and they must be controlled within a specified range to be qualified products.

[0013] The present invention will now be further described with reference to the accompanying drawings.

[0014] like Figure 1 and Figure 2 As shown: A full-inspection automatic weight detection device includes a frame 1, a feeding mechanism 2 mounted on top of the frame 1, the feeding mechanism 2 being driven by a feeding motor 21 to transport ferrite cores 3 to a suction station 22; a translational suction and release mechanism 4 mounted above the feeding mechanism 2 to pick up ferrite cores 3 from the suction station 22; a balance bracket 6 mounted in front of the frame 1, with an electronic balance 5 horizontally placed on the balance bracket 6; and a discharge mechanism 7 on the other side of the balance bracket 6. The electronic balance 5 is centrally positioned between the feeding mechanism 2 and the discharge mechanism 7, so that the ferrite cores 3 are placed on the central disk 51 of the electronic balance 5 during weight detection. The discharge mechanism 7 is driven by a discharge motor 71 to automatically output the ferrite cores 3 to the next arrangement process.

[0015] like Figure 3As shown: The above-mentioned translational suction and release mechanism 4 is driven by a servo motor 41 to drive the slide table 43 on the linear module 42 to perform translational linear motion. The slide table 43 is equipped with a moving plate 44, and the front end of the moving plate 44 is equipped with a lifting cylinder 45. The lifting cylinder 45 can lift the top connecting plate 46. Two suction and release cylinders 47 are installed at both ends of the connecting plate 46 at equal distances from the lifting cylinder 45. The forward and backward translational distance of the slide table 43 is set to be the same as the distance between the two suction and release cylinders 47. The suction and release cylinders 47 are connected to suction cups 48.

[0016] The suction cup 48 is filled with a magnet 488 and has a stainless steel suction cup shell 489. The magnet 488 inside the suction cup 48 can move up and down with the extension and retraction of the suction and release cylinder 47 to attract and release the ferrite core 3.

[0017] The aforementioned lifting cylinder 45 is equipped with an air blowing valve 49 on one side, which can periodically blow air to clean the dust on the electronic balance 5. The electrical system can be set to automatically zero the electronic balance 5 periodically to reduce the error in weight detection.

[0018] Operating procedure: The ferrite core 3 is conveyed to the suction station 22 by the feeding mechanism 2. The lifting cylinder 45 retracts the connecting plate 46, the suction cup 48 descends, the suction and release cylinder 47 extends, and the magnet 488 inside the suction cup 48 descends to attract the ferrite core 3. The ferrite core 3 is then lifted forward by the translation suction and release mechanism 4 and moved above the center plate 51 of the electronic balance 5. The ferrite core 3 is then lowered onto the center plate 51 for weight detection. The suction cup 48 is then lifted and moved backward to the suction station 22. The two suction cups descend simultaneously to pick up the ferrite core 3 from the suction station 22 and the center plate 51 of the electronic balance 5. The ferrite core 3 on the center plate 51 is picked up and released onto the discharge mechanism 7, while the ferrite core 3 on the suction station 22 is picked up and released onto the center plate 51. This process is repeated continuously. The two suction cups 48 alternately pick up and release the ferrite core 3, automatically completing the weight detection of the ferrite core 3 one by one.

[0019] If the weight test fails, the electrical system will automatically sound and light an alarm to remind the operator to remove the defective product. If the weight test fails three times in a row, the system will prompt the machine to stop and adjust the press mold in time, thereby reducing unnecessary losses and ensuring product quality.
