[0019] Referring to Figures 1 to 3 , a device for detecting the weight of an iron core according to the present utility model includes a workbench 1, a conveyor belt 2 installed on the workbench 1, a baffle 3 provided on the conveyor belt 2 for blocking the advancement of the iron core 10, conversion plates 4 and pushing cylinders 5 respectively arranged on the left and right sides of the conveyor belt 2, and a weighing device installed on the workbench 1 and directly below the conversion plate 4; the finished iron cores 10 coming off the iron core 10 production line enter the conveyor belt 2 for transportation one by one. When the leading iron core 10 encounters the baffle 3 and is blocked, the iron cores 10 are arranged in a row in sequence on the conveyor belt 2;

[0020] The top surface of the mold-changing plate 4 is provided with a rectangular notch groove 9 for accommodating the iron core 10, and the length of the notch groove 9 is an integral multiple of the diameter of the iron core 10; a plurality of mold-changing plates 4 with notch grooves 9 of different sizes can be provided according to the different diameters of the iron cores 10 of different specifications and the number of the iron cores 10. For example: the diameter of the iron core 10 is 100mm, and four iron cores 10 are weighed at one time, then the length of the notch groove 9 of the mold-changing plate 4 is 400mm, that is, the total length of the four iron cores 10 arranged in a line is 400mm, and the four iron cores 10 are all accommodated in the notch groove 9, which is convenient for positioning and weighing; when the diameter of the iron core 10 is different, or the number of iron cores 10 weighed at one time is different, it is only necessary to replace the mold-changing plate 4 with the corresponding notch groove length;

[0021] The movable end of the pushing cylinder 5 is equipped with a push plate 51 parallel to the forward direction of the conveyor belt 2; the length of the push plate 51 is an integer multiple of the diameter of the iron core 10, which is similar to the setting principle of the length of the notch groove 9. If the above-mentioned case of weighing four 100mm diameter iron cores 10 at a time is used, the length of the push plate 51 needs to reach 400mm, ensuring that the four iron cores 10 can be pushed from the conveyor belt 2 into the notch groove 9 of the change plate 4 at the same time; a vertical baffle 52 perpendicular to the push plate 51 is provided at the left end of the push plate 51. When the push plate 51 pushes a group of iron cores 10 into the notch groove 9, the vertical baffle 52 is located above the conveyor belt 2, which can block the next group of iron cores 10 from continuing to move forward. After the previous group of iron cores 10 enters the notch groove 9, the push plate 51 retreats and resets, and the next group of iron cores 10 are no longer blocked by the vertical baffle 52 and continue to move forward to the baffle 3 to be arranged in sequence, and the next group of iron cores 10 can be pushed;

[0022] The weighing device comprises a lifting cylinder 6 vertically mounted on the workbench 1, a crossbeam 61 mounted on the workbench 1 for fixing the lifting cylinder 6, a support plate 62 and a top plate 63 mounted at the movable end of the lifting cylinder 6, and a weighing sensor 7 mounted between the support plate 62 and the top plate 63 at the movable end of the lifting cylinder 6; a guide mechanism is provided between the support plate 62 and the crossbeam 61 to ensure the stability of the lifting process of the support plate 62, and the guide mechanism comprises a guide sleeve 64 fixedly mounted on the crossbeam 61, and a guide column 65 fixedly mounted on the support plate 62, and the guide column 65 is slidably embedded in the guide sleeve. into the sleeve 64; the lifting cylinder 6 lifts the support plate 62 and the top plate 63 upwards, and the top plate 63 further lifts the mold-changing plate 4 to separate it from the workbench 1. At this time, the weighing sensor 7 measures the total weight of the top plate 63, the mold-changing plate 4 and the iron core 10 group, and the weights of the top plate 63 and the mold-changing plate 4 are known, so it is easy to get the weight of the iron core 10 group. According to the standard weight of the iron core 10 of this specification and the allowable deviation range, it can be determined whether the weight of the group of iron cores 10 is qualified. These calculation processes are all automatically calculated by the production line control system, which can effectively distinguish the measurement accuracy, and the measurement speed is fast and the efficiency is high;

[0023] When the measured weight of the iron core 10 is unqualified, an NG conveyor belt 8 for collecting the iron cores 10 with unqualified weight measurement is arranged on one side of the workbench 1, and the unqualified iron cores 10 are placed on the NG conveyor belt 8 for isolation treatment from the qualified products.

[0024] The utility model uses a push plate 51 to push a group of multiple iron cores 10 into the conversion plate 4 at one time, and then the weighing device weighs the conversion plate 4 and the iron cores 10 as a whole, so as to obtain the weight of the whole group of iron cores 10. The overall equipment structure is simple, the weight of the iron cores 10 can be quickly measured, and through the accurate and high-efficiency measurement of the weight of the iron cores 10, the performance of the motor after assembly can be effectively improved, the production efficiency and the quality control level can be improved, and the market competitiveness can be improved.

[0025] In addition, it should be noted that the above specific implementation manner is only an optimized solution of this patent, and any changes or improvements made by those skilled in the art according to the above conceptions are within the protection scope of this patent.
