DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-3 As shown, the NdFeB strip thickness automatic measuring device includes a box body 1, a mounting plate 2, a circular vibration plate 5, a linear vibrator 7, a discharge track 6, a rotating motor 3, a feed plate 4, and a laser displacement sensor 10;

[0023] A mounting plate 2 is fixed in the middle of the box 1, a pulley is provided at the bottom of the box 1, and a rotating motor 3 is fixed at the top of the mounting plate 2. The rotating motor 3 uses a large-torque DC brushless servo reduction motor with small vibration and smooth operation, which increases the stability of product detection. A horizontally arranged feed tray 4 is fixed at the output end of the rotating motor 3. The function of the box 1 is to prevent the wind from blowing the NdFeB belt-swinging piece on the feed tray 4 away from the measuring channel 11, thereby reducing the interference to the thickness measurement. At the same time, the box 1 also has a certain anti-noise function to reduce the interference to the surrounding environment during the measurement process.

[0024] The discharge port of the circular vibration disk 5 is fixedly connected to the entrance of the discharge track 6. A linear vibrator 7 is fixed to the bottom end of the discharge track 6. The outlet of the discharge track 6 is movably abutted against the top of the feed tray 4. The linear vibrator 7 is utilized to ensure that the NdFeB strips coming out of the circular disk vibrator are smoothly transported to the feed tray 4 via the discharge track 6.

[0025] A material-pickup component 8 is fixed on the mounting plate 2 on one side of the feed tray 4, and a poke rod 8.2 of the material-pickup component 8 is placed above the feed tray 4. When the feed tray 4 is rotated by the rotating motor 3, the NdFeB strip with measured thickness is pushed into the receiving box 12 by the material-pickup component 8.

[0026] A fine-tuning platform 9 is fixedly provided on the mounting plate 2 between the material-selecting component 8 and the linear vibrator 7, and a pair of laser displacement sensors 10 arranged opposite to each other up and down are fixed on the fine-tuning platform 9. The feeding tray 4 is rotatably arranged between the two laser displacement sensors 10, and a measuring channel 11 arranged opposite to the laser displacement sensor 10 is provided on the feeding tray 4. The positions of the two laser displacement sensors 10 are adjusted by using the fine-tuning platform 9, so that the laser displacement sensors 10 can be shot at each other through the measuring channel 11, and the accuracy of the relative position is greatly improved. At the same time, the shot laser displacement sensors 10 can send the detected data to the host computer, so that the host computer can store the data.

[0027] The material shifting component 8 includes a rotating shaft 8.1, a shifting rod 8.2, and a brush 8.3. The rotating shaft 8.1 is rotatably set on the mounting plate 2. The top of the rotating shaft 8.1 is fixedly connected to a horizontally set shifting rod 8.2. The bottom of the shifting rod 8.2 is fixed with a brush 8.3. The brush 8.3 is in active contact with the top of the feeding tray 4. The NdFeB strip after measurement is shifted into the receiving box 12 by the brush 8.3. A double-row hard brush 8.3 is used to guide the material collection, which effectively prevents product leakage and wear of the feeding tray 4.

[0028] A material receiving box 12 is provided on the mounting plate 2 below the material shifting component 8 .

[0029] A first support rod 13 is fixed on the mounting plate 2 on one side of the circular vibration disk 5, the top end of the support rod is connected to a second support rod 15 via a ball joint bearing 14, a magnet 16 is fixed to the end of the second support rod 15, and the magnet 16 is used to clear the circular vibration disk 5 to avoid production anomalies such as batch mixing caused by products left in the circular vibration disk 5.

[0030] A screening slot 17 is provided on the discharge track 6 to screen out products whose outer dimensions do not meet the inspection standards.

[0031] After using this equipment, the number of manpower is reduced from two to one, solving the problems of high labor intensity, low efficiency and high error rate in random inspection of NdFeB strips. The work of employees is changed from taking materials, measuring, recording, calculating and receiving materials to adding materials and receiving materials, which improves work efficiency.

[0032] The specific operation process of this embodiment is as follows:

[0033] The same batch of products are placed in the circular vibration plate 5 and arranged by the circular vibration plate 5. The circular vibration plate 5 discharges the products from the outlet to the discharge track 6. Under the action of the linear vibrator 7, the products on the discharge track 6 are sent to the feeding plate 4. Products whose external dimensions do not meet the inspection standards fall through the screening slot 17 on the discharge track 6 to assist in screening.

[0034] When the product enters the feeding tray 4, the laser displacement sensor 10 detects the thickness of the product under the rotation of the feeding tray 4. After the detection, the product is rotated to the material shifting component 8. Under the cooperation of the material shifting component 8 and the feeding tray 4, the product is shifted to the receiving box 12.

[0035] After the number of products tested in the same batch meets the standard, rotate the second support rod 15 so that the magnet 16 rotates above the circular vibration disk 5. Under the action of the magnetic force, the remaining iron boron strips in the circular vibration disk 5 are sucked out, and the next batch of iron boron strips can be tested.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
