Description

Technical Field

[0001] This utility model relates to the field of differentiation devices, specifically to a differentiation device for stainless steel products of different material grades. Background Technology

[0002] Currently, there are many types of heat spreaders made of stainless steel. Different grades of stainless steel have little difference in surface finish after processing, which poses a risk of material mixing. Using a spectrometer for measurement is costly and inefficient.

[0003] A prior art patent, CN119023591A, discloses a method that utilizes the photochemical effect of lasers to control laser process parameters. This allows the laser to act on different stainless steel surfaces, resulting in oxide layers and oxides of varying thicknesses due to their different compositions and properties. The light passing through these surfaces will then display different colors, thus distinguishing between different types of stainless steel. This invention is highly environmentally friendly. It uses lasers to color stainless steel sheets, creating different colors to differentiate between them. The laser produces an extremely thin oxide layer on the stainless steel surface, generating no pollutants throughout the process. Furthermore, because this application distinguishes stainless steel types using the same laser parameters applied to different stainless steels, this technology can be used on production lines. After laser coloring, subsequent processes can directly differentiate and process the stainless steel, significantly reducing time.

[0004] However, as the device was put into production and used, its shortcomings gradually became apparent, mainly in the following aspects:

[0005] Currently, there are many types of vapor chambers made of stainless steel. Different grades of stainless steel have little difference in surface appearance after processing, which poses a risk of material mixing. Measuring these materials using a spectrometer is costly and inefficient.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a device for distinguishing stainless steel products of different grades. This device solves the problems of traditional heat spreaders being made of various types of stainless steel, with little difference in surface finish after processing, leading to the risk of material mixing. It also addresses the issues of high cost and low efficiency when using a spectrometer for measurement.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A device for distinguishing stainless steel products of different grades includes a support base plate. Magnets are arranged side by side above the support base plate corresponding to each stainless steel product. A material tray is supported above several magnets by a partition plate. Several stainless steel products of different grades are arranged side by side on the material tray. Hall sensors are moved together in the area above several stainless steel products.

[0010] As an optimized solution, several of the magnets are connected to the support base plate by a magnet fixing structure.

[0011] As an optimized solution, the supporting base plate is also provided with a magnet spacing adjustment structure for adjusting the spacing between adjacent magnet fixing structures.

[0012] As an optimized solution, the tray is equipped with a product spacing adjustment structure to adjust the spacing between adjacent stainless steel products.

[0013] As an optimized solution, the magnet fixing structure includes a fixing base, the upper surface of which has a groove, and the lower end of the magnet is fixed in the groove.

[0014] As an optimized solution, the magnet spacing adjustment structure includes a square column vertically fixed to the lower end of each of the fixed seats, and the upper surface of the support base plate is provided with a number of square grooves that match the square columns along the magnet arrangement direction.

[0015] As an optimized solution, the product spacing adjustment structure includes a storage trough opened at the top of the material tray, the stainless steel products are supported on the bottom surface of the storage trough, and two product positioning plates are inserted side by side on the bottom surface of the storage trough corresponding to each stainless steel product, forming a product positioning area between the two product positioning plates.

[0016] As an optimized solution, two positioning posts are fixedly connected side by side to the lower surface of the product positioning plate, and two rows of positioning grooves matching the positioning posts are arranged side by side on the bottom surface of the storage tank. Each row of positioning grooves has several grooves arranged side by side along the stainless steel product arrangement direction.

[0017] As an optimized solution, the product positioning plate has a pick-up and drop hole on the side wall near the upper end.

[0018] As an optimized solution, a positioning structure is provided between the material tray and the supporting base plate.

[0019] As an optimized solution, the positioning structure includes guide posts that are vertically fixed to the support base plate in parallel, and the material tray has guide holes that match the guide posts.

[0020] As an optimized solution, the support base plate has a vertical insertion groove along its length, and the lower end of the guide post is inserted into the insertion groove.

[0021] As an optimized solution, a countersunk threaded hole communicating with the insertion slot is horizontally opened on the side wall of the support base plate, and a fixing screw that abuts against the guide post is internally threaded in the countersunk threaded hole.

[0022] As an optimized solution, connecting lugs are fixedly connected to the opposite sidewalls of the support base plate.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] By setting up a magnet spacing adjustment structure, the spacing between the magnets can be adjusted. The position of the stainless steel product can be adjusted according to the position of the magnets using the product spacing adjustment structure.

[0025] By using the product spacing adjustment structure, the magnet spacing adjustment structure, and the guide column, the position of the support base plate, magnet, material tray, and stainless steel products can be defined, making it easier to distinguish them using Hall sensors.

[0026] The support base plate is fixed to the base plate of the automated equipment via connecting ear plates. The Hall sensor is connected to the robotic arm of the automated equipment. When the robotic arm moves the Hall sensor to the corresponding position of the product, the Hall sensor with the corresponding detection threshold is selected because different grades of stainless steel have different magnetic flux to the corresponding magnets. When the magnetic flux reaches the threshold of the Hall sensor, an alarm is triggered, thus distinguishing stainless steel products of different grades. This solution is convenient and quick. This solution is easy to operate, highly accurate, and can be implemented in automated systems to improve detection efficiency. Attached Figure Description

Detailed Implementation

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0032] like Figure 1 and Figure 2 As shown, the device for distinguishing stainless steel products of different grades includes a support base plate 1. Magnets 7 are arranged in parallel above the support base plate 1 for each stainless steel product 10. A material tray 3 is supported above the magnets 7 by a partition plate 8. Several stainless steel products 10 of different grades are arranged in parallel on the material tray 3. Hall sensors 17 are moved together in the area above the several stainless steel products 10.

[0033] The Hall sensor 17 can be connected to the robotic arm via a bracket. One end of the bracket is fixed to the end effector (or motion axis slider) of the robotic arm with bolts, and the other end has a pre-drilled sensor mounting hole. The Hall sensor 17 is fixed in the hole by locking nuts or screws.

[0034] By setting up the isolation plate 8, the magnet 7 can be prevented from directly contacting the tray 3, thus reducing wear.

[0035] Several magnets 7 are connected to the support base plate 1 through a magnet 7 fixing structure.

[0036] The base plate 1 is also provided with a magnet spacing adjustment structure for adjusting the spacing between adjacent magnets 7 fixing structures.

[0037] The tray 3 is equipped with a product spacing adjustment structure to adjust the spacing between adjacent stainless steel products 10.

[0038] The magnet 7 fixing structure includes a fixing base 5, the upper surface of which has a groove, and the lower end of the magnet 7 is fixed in the groove.

[0039] The magnet 7 spacing adjustment structure includes a square column 6 vertically fixed to the lower end of each fixed base 5, and a number of square grooves 4 matching the square column 6 are arranged side by side on the upper surface of the support base plate 1 along the arrangement direction of the magnets 7.

[0040] The product spacing adjustment structure includes a storage trough 9 opened on the top of the material tray 3. Stainless steel products 10 are supported on the bottom surface of the storage trough 9. Two product positioning plates 11 are inserted side by side on the bottom surface of the storage trough 9 corresponding to each stainless steel product 10, and a product positioning area is formed between the two product positioning plates 11.

[0041] Two positioning posts 13 are fixedly connected side by side to the lower surface of the product positioning plate 11. The bottom surface of the storage tank 9 is provided with two rows of positioning grooves 12 that match the positioning posts 13. Each row of positioning grooves 12 is provided with several in parallel along the arrangement direction of the stainless steel product 10.

[0042] The product positioning plate 11 has a pick-and-place hole 14 on the side wall near the upper end for easy pick-and-place.

[0043] A positioning structure is provided between the material tray 3 and the supporting base plate 1.

[0044] The positioning structure includes guide posts 2 that are vertically fixed to the support base plate 1 in parallel, and guide holes matching the guide posts 2 are provided on the material tray 3.

[0045] The support base plate 1 has a vertical insertion groove along its upper edge, and the lower end of the guide post 2 is inserted into the insertion groove.

[0046] The side wall of the support base plate 1 is provided with a countersunk threaded hole that connects to the insertion slot, and a fixing screw 15 that abuts against the guide post 2 is connected to the countersunk threaded hole.

[0047] Connecting lugs 16 are fixedly attached to the opposite side walls of the supporting base plate 1.

[0048] The innovation of this solution lies in its structure. The specific automation control is common in daily life, so it will not be elaborated on here. For example:

[0049] Basic assembly: First, fix the magnet 7 to the support base plate 1, lay the isolation plate 8 on top of the magnet 7, then place the product tray 3 on the isolation plate 8, and finally place the different grades of stainless steel products 10 to be tested in the tray 3.

[0050] Test preparation: Based on the different effects of different grades of stainless steel (such as 304, 316, 430, etc.) on the magnetic flux of magnet 7, preset the corresponding detection threshold of Hall sensor 17 (different grades of stainless steel have different magnetic permeability, which will lead to differences in the magnetic flux passing through the product).

[0051] Dynamic detection: The robotic arm of the automated equipment carries a Hall sensor 17 and moves along a preset path above the material tray 3. When the sensor moves to the corresponding position directly above a product, the sensor detects the magnetic flux passing through the product in real time.

[0052] Signal feedback and differentiation: If the detected magnetic flux reaches the preset threshold, the Hall sensor 17 triggers an alarm signal and records the corresponding label of the product through the automatic control system; if the threshold is not reached, it is determined to be a product with other labels, and the motion axis continues to move to the next product position to repeat the detection, so as to achieve accurate differentiation of stainless steel products 10 with different labels.

[0053] The working principle of this device is as follows:

[0054] By setting up a magnet 7 spacing adjustment structure, the spacing of the magnets 7 can be adjusted. The position of the stainless steel product 10 can be adjusted according to the position of the magnets 7 through the product spacing adjustment structure.

[0055] The product spacing adjustment structure, the magnet 7 spacing adjustment structure and the guide column 2 are used to limit the position of the support base plate 1, magnet 7, material tray 3 and stainless steel product 10, so that the Hall sensor 17 can be used to distinguish them.

[0056] The support base plate 1 is fixed to the base plate of the automated equipment via connecting ear plates 16. The Hall sensor 17 is connected to the robotic arm of the automated equipment. When the robotic arm carries the Hall sensor 17 to the corresponding position of the product, the Hall sensor 17 with the corresponding detection threshold is selected because different grades of stainless steel have different magnetic flux to the corresponding magnet 7. When the magnetic flux reaches the threshold of the Hall sensor 17, an alarm is triggered, thus distinguishing stainless steel products 10 of different grades. This solution is convenient and quick. This solution is easy to operate, highly accurate, and can be implemented in automated solutions to improve detection efficiency.
