Description

Technical Field

[0001] The utility model relates to a thickness measuring device, which is particularly suitable for thickness testing of a quick-setting alloy sheet. Background Art

[0002] The thickness of alloy quick-setting thin sheets is one of the important indicators for judging the quality of the strip. The traditional method for measuring the thickness of alloy quick-setting thin sheets is: after the product is produced and released from the furnace, the tester selects a certain number of thin sheets and manually tests them using a micrometer. This traditional testing method has the following two problems:

[0003] 1. Failure to select product samples in a balanced manner. This is because the testers' subjective behavior can lead to data bias. Testers only randomly grab samples and tend to favor samples that are easier to grab, while ignoring relatively small samples, resulting in distorted test results.

[0004] 2. Traditional testing methods are inefficient. Utility Model Content

[0005] This utility model proposes an automatic thin-sheet thickness test device to solve the drawbacks of existing manual operation. The utility model automatically loads the material by setting a spiral feeder and selects samples of standard specifications as much as possible through sorting. The utility model lays the thin sheet flat on a rotating table and then uses the laser distance measurement principle to test the sheet thickness, which greatly reduces the error. In addition, no manual operation is required during the process, saving time and labor, and the test efficiency is high and the results are more accurate.

[0006] The technical solution of the utility model is as follows: an automatic testing device for the thickness of thin sheets, including a spiral vibrating loader and a thickness measuring mechanism, the thickness measuring mechanism including a rotating table, a gap is provided on the rotating table, the spiral vibrating loader transports the material to the gap position, and a group of laser beam sensors are correspondingly provided at the upper and lower positions of the gap.

[0007] Furthermore, a circle of gaps is provided on the circumference of the rotating table, and the width of the gaps is smaller than the thickness of the sheet to be inspected.

[0008] Furthermore: the spiral vibration loader includes a chassis, a spiral vibration disk and a linear feeder; the spiral vibration disk has a spiral groove, and a bevel is provided on the groove edge of the spiral groove, and the bevel is connected between the higher-level spiral groove and the lower-level spiral groove, and the height of the bevel is higher than the thickness of one thin sheet and less than the thickness of two thin sheets.

[0009] Furthermore, an anti-overlapping sliding piece is provided in the higher-level spiral groove at the groove, and the anti-overlapping sliding piece is at the same height as the groove surface.

[0010] Furthermore, a filter port is provided in the spiral groove of the spiral vibrating disk, and the width of the filter port is smaller than a set minimum thickness of the sheet to be processed.

[0011] Furthermore: a material collecting brush is arranged on the rotating table at a position away from the feeding, and a material collecting box is arranged below the rotating table.

[0012] The technical advantages of this utility model are as follows: by providing a bevel on the spiral groove of the automatic spiral feeder, thin slices automatically slide down after exceeding a certain thickness, preventing stacking. A filter is also provided during the material transport process to filter out small slices. A rotating table with a gap is provided, and thin slices are laid across the gap. Laser sensors are positioned above and below the gap to measure the thickness of the slices using the laser ranging principle. Without interference from slices in the gap, the measurement is more accurate. This utility model eliminates the need for manual inspection, saving labor and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the disclosed drawings and embodiments are only for illustrative purposes and are not intended to limit the scope of protection of the present invention.

[0018] like Figure 1 and 2As shown, the utility model provides an automatic testing device for the thickness of thin films, which adopts a spiral vibrating loader 1 for automatic loading. The core working principle of the spiral vibrating loader 1 is to make the spiral vibrating disk vibrate vertically and torsionally through the combination of a pulse electromagnet and an inclined spring sheet, thereby realizing the spiral rise and orderly transportation of the material. Its main components include a chassis 11, a spiral vibrating disk 12 and a linear feeder 13; the chassis 11 is driven by a motor to provide pulse vibration, the chassis 11 provides support for the spiral vibrating disk 12, and is connected to the spiral vibrating disk 12 through a spring plate, so that the spiral vibrating disk 12 vibrates vertically and also torsionally vibrates around its vertical axis; the linear feeder 13 is connected to the discharge port of the spiral vibrating disk 12.

[0019] The present invention makes certain improvements to the spiral vibrating feeder 1, such as Figure 1 As shown, in the spiral vibrating feeder 1, the spiral vibrating disk 12 has an ascending spiral groove. The utility model provides a groove 14 on the spiral groove of the spiral vibrating disk 12. The groove is connected between the higher spiral groove and the lower spiral groove. Its function is to guide the material in the higher spiral groove to the lower spiral groove, thereby preventing lamination. Specifically, in the utility model, the height of the groove 14 is set to be higher than the thickness of one thin sheet and less than the thickness of two thin sheets. In this way, only one thin sheet can be retained in the higher spiral groove flowing through the groove, and the rest will slide through the groove into the lower spiral groove, thereby preventing lamination and ensuring that the thin sheets are output in single pieces when they are finally output.

[0020] Furthermore, such a groove 14 can be provided on the groove edge of each level of the spiral groove, so as to prevent the lamination of the slices from occurring during the ascending process step by step.

[0021] Furthermore, an anti-overlapping sliding piece 15 can be provided in the higher spiral groove at the groove 14. The anti-overlapping sliding piece is smoother than the groove surface, which can further promote the sliding of the sheet along the groove. The anti-overlapping sliding piece 15 is at the same height as the groove surface.

[0022] Another improvement made by the present invention is that a filter port 16 is provided in the spiral groove of the spiral vibrating disk 12. The filter port 16 is set according to a custom size. The purpose is to allow the flakes smaller than the size of the filter port to leak out and only leave the flakes larger than the size of the filter port. In this way, the specifications of the flake samples finally output can be more uniform.

[0023] Furthermore, because this device measures the thickness of the slices, the purpose of filtering is to filter out slices with specific thicknesses and retain most slices with consistent thicknesses. Therefore, the slot opening of the filter port 16 is also designed according to the predetermined slice thickness so that the slot can leak slices with relatively small thicknesses.

[0024] The above describes the improvement of the spiral vibrating feeder 1. The present invention is a device for testing the thickness of thin slices. In addition to the spiral vibrating feeder 1 for feeding, the present invention also provides a thickness measuring mechanism 2.

[0025] The thickness measuring mechanism 2 includes a rotating table 21 with a circumferential gap 22 formed around the circumference. The gap is narrow enough to prevent thin slices from leaking through. The linear feeder 13 of the spiral vibrating loader 1 is directly connected to the gap 22. A pair of laser beam sensors 23 are symmetrically positioned above and below the gap 22. These laser beam sensors 23 comprise a laser transceiver and a laser reflector. When the rotating table rotates and carries the thin slice in the gap past the laser beam sensors 23, the laser beam sensors sense it and measure the thickness of the thin slice using the principle of laser ranging. The thin slice thickness measured by this utility model using the laser ranging principle is more accurate than manual measurement with a caliper.

[0026] It is also possible to consider making the turntable 21 into a glass table, or providing a circle of glass belt on the circumference of the turntable 21. However, it is generally found that this structure with a gap in the turntable is better than a turntable made of glass. The laser will not be attenuated or refracted, which improves the accuracy of the test.

[0027] Furthermore, a collecting brush 24 is provided on the rotating table 21 at a position away from the feeding port, and a collecting box 25 is provided below the rotating table 21. The tested slices on the rotating table 21 are collected in the collecting box, so that the rotating table surface is clean so as to receive the next batch of slices to be tested when it rotates to the feeding port.

[0028] To use this device, a worker first pours a bag of flakes into the spiral vibrating feeder 1. The vibrating feeder 1 vibrates to feed the flakes. Any overlapping flakes are separated and picked up by a bevel 14 and anti-overlapping slide 15. During this process, any particularly fine particles or flakes are filtered out through a filter 16. Finally, the vibrating feeder 1 delivers qualified flakes to the thickness measuring mechanism 2. The rotating table 21 then rotates, driving the flakes along its surface. Slits are positioned on the table, and the thickness of the flakes at these locations is measured by a laser sensor. Finally, the tested flakes are collected by a collection brush 24 and placed in a collection bin 25.

[0029] The above description is only a preferred embodiment and an explanation of the technical principles used. Those skilled in the art should understand that other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept should also be within the scope of protection of this utility model.
