Description

Technical Field

[0001] The utility model relates to the technical field of weighing devices, in particular to a magnet weighing and screening machine. Background Art

[0002] With the widespread application of electronic products, magnets are increasingly used in electronic products. The weight of a magnet is related to its volume. A larger volume means a heavier weight, while a smaller volume means a lighter weight. In precision electronic instruments, the weight and volume requirements for magnets are relatively strict. If the magnet is too heavy or too large, it will affect the placement and operation of other electronic components in the instrument, and over time it will damage the instrument, rendering it unusable.

[0003] Therefore, there is an urgent need for a magnet weighing and screening machine. Utility Model Content

[0004] The purpose of the utility model is to provide a magnet weighing and screening machine to address the deficiencies of the existing technology. The utility model can automatically weigh and screen magnets one by one, with high efficiency and accurate screening.

[0010] Preferably, the fixed plate is further provided with a CCD positioning component, and the CCD positioning component is arranged beside the lifting L-shaped plate.

[0011] The beneficial effects of the present invention are as follows: first, the operator places the magnet to be weighed in the loading tray, and the suction cup of the first clamping device is precisely positioned through the XYZ three-axis to clamp the magnet in the loading tray, and then driven by the first driving mechanism, the first clamping device is displaced to the weighing device, and the magnet is placed on the weighing panel.

If the weighing data of the magnet is unqualified, the controller sends a signal to the driving motor, the driving motor is reversed, and the toggle piece swings to dial the magnet into the NG product recovery tray on the lower side. When the toggle piece of this embodiment is not working, the direction is located in the opposite direction of the weighing device, which effectively avoids the toggle piece affecting the weighing of the magnet.

[0018] In this embodiment, the operator first places the magnet to be weighed in the loading tray 2, and the suction cup 31 of the first clamping device 3 is precisely positioned through the XYZ three axes to clamp the magnet in the loading tray 2. Then, the first clamping device 3 is driven by the first driving mechanism 32 to move to the weighing device 4, and the magnet is placed on the weighing panel 41. After the weighing sensor 42 senses the gravity generated by the magnet, it transmits the data to the controller (not shown in the figure).
