Therefore, precise measurement of it is an essential link. In traditional core height measurement, the core height measurement system mainly consists of a measuring plate, a fixing plate, adjusting bolts, and guide pins. When using the core height measurement system, first place the fixing plate in an appropriate position, and then adjust the measuring plate to a suitable height and position through the adjusting bolts and guide pins so that it can closely fit the upper surface of the core; obtain the core height measurement data by reading the scale on the measuring plate or using other auxiliary measuring tools.

[0008] The pushing mechanism pushes the core on the feeding conveyor belt directly below the pressing cylinder of the height measuring mechanism. The movable end of the pressing cylinder presses down to touch the top of the core, and the displacement sensor monitors the downward displacement of the movable end of the pressing cylinder, thereby measuring the core height;

Detailed implementation

[0023] See Figures 1 to 3 , a core height measurement mechanism involved in the present utility model includes a feeding conveyor belt 1, a discharging conveyor belt 2 arranged perpendicular to the feeding conveyor belt 1, a height measurement mechanism 3 arranged between the feeding conveyor belt 1 and the discharging conveyor belt 2, a pushing mechanism 4 arranged on the feeding conveyor belt 1 for pushing the core 8 on the feeding conveyor belt 1 to the height measurement mechanism 3, and an NG material handling mechanism 5 arranged on the discharging conveyor belt 2; a stop plate 6 for blocking the position of the core 8 and a proximity sensor 7 for sensing the core 8 are arranged on the feeding conveyor belt 1; the feeding conveyor belt 1 continuously conveys the cores 8 on the production line, and they are arranged one by one at the pushing mechanism 4 under the block of the stop plate 6. When the proximity sensor 7 senses that there is a core 8 at the stop plate 6, a signal indicating that the core 8 is in place is sent.

[0024] The pushing mechanism 4 includes a pusher block 42 driven by a sliding cylinder 41 to push the core 8 to the height measurement mechanism 3; a stop bar 43 is arranged on the back of the pusher block 42; after the core 8 is in place, the sliding cylinder 41 drives the pusher block 42 to push the core 8 out of the feeding conveyor belt 1 and send it into the height measurement mechanism 3. During the pushing process, the stop bar 43 blocks the subsequent cores 8 from advancing along with the feeding conveyor belt 1. After the pusher block 42 retracts to the in-place position, the subsequent cores 8 continue to advance to the stop plate 6, triggering the next set of pushing actions.

[0025] The height measurement mechanism 3 includes a support base 31, a press-fitting cylinder 32 vertically installed upside down on the support base 31, and a displacement sensor 33 for monitoring the displacement distance of the movable end of the press-fitting cylinder 32; the support base 31 includes a column 34, a cross beam 35, and a movable beam 36 slidably sleeved on the column 34; a press head 37 is installed on the movable beam 36; the press-fitting cylinder 32 is installed on the cross beam 35, and the movable end of the press-fitting cylinder 32 is movably connected to the movable beam 36. A pressure sensor 38 is arranged between the movable end of the press-fitting cylinder 32 and the press head 37 for monitoring the pressure acting on the core 8 to ensure that the pressure is controlled between 8 kg and 150 kg; the displacement sensor 33 is installed on the movable beam 36 for monitoring the displacement amount of each downward press of the press head 37.

[0026] The pusher mechanism 4 pushes the iron core 8 on the feeding conveyor belt 1 directly below the pressing head 37 of the pressing cylinder 32 of the height measuring mechanism 3. The movable end of the pressing cylinder 32 presses down to drive the pressing head 37 to touch the top of the iron core 8. The displacement sensor 33 monitors the downward displacement of the movable end of the pressing cylinder 32, and thus the height of the iron core 8 can be measured. After the measurement is completed, the pressing cylinder 32 drives the pressing head 37 to rise. The pusher block 42 of the pusher mechanism 4 pushes the next iron core 8 into the height measuring mechanism 3, and this iron core 8 to be measured then pushes the previously measured iron core 8 into the discharging conveyor belt 2.

[0027] The NG material processing mechanism 5 separates and processes the iron cores 8 with unqualified height detection, including an NG pusher cylinder 51 and an NG discharging conveyor belt 52 respectively arranged on both sides of the discharging conveyor belt 2, and an NG stop cylinder 53 arranged on the discharging conveyor belt 2. The iron cores 8 with qualified height detection are conveyed by the discharging conveyor belt 2 to the next process. If an iron core 8 with unqualified height is detected, that is, an NG iron core, the NG stop cylinder 53 moves down to block the NG iron core. Subsequently, the NG pusher cylinder 51 pushes the NG iron core into the NG discharging conveyor belt 52, and the NG discharging conveyor belt 52 sends the NG iron core into the non-conforming product area.

[0028] The structure of the utility model is simple. The feeding and discharging of iron cores, height detection, and separation and control of non-conforming products are all realized by automatic operation. The height measurement is fast, accurate, and can be continuously measured without interruption, without manual participation, improving production efficiency, reducing production costs, and at the same time can be seamlessly integrated into the automatic production line.

[0029] In addition, it should be noted that the above specific implementation manner is only an optimized solution of this patent. Any modification or improvement made by those skilled in the art according to the above conceptions is within the protection scope of this patent.
