Description

Technical Field

[0001] This utility model relates to the field of Mohs hardness technology, and in particular to an automatic Mohs hardness testing device. Background Technology

[0002] Mohs hardness is measured by scratching the surface of a mineral using the scratch test. The hardness is expressed on a ten-point scale, representing a relative hardness, which is relatively coarse. The hardness of the tested mineral is determined by comparing it to ten reference minerals through a scratch test. If a reference mineral can scratch the tested mineral, the Mohs hardness is less than that reference mineral; if it cannot scratch the mineral, the Mohs hardness is greater than that reference mineral.

[0003] Almost all cover plate products require hardness testing, including Mohs hardness testing. Currently, testing is done manually using a pen, which can lead to inaccurate results due to variations in force. Furthermore, having to retrieve the pen from a specific area for each test is time-consuming and inconvenient.

[0004] For example, the Chinese invention patent entitled "A Device for Constant Pressure Testing of Mohs Hardness of Samples" published in Chinese Patent Publication No. CN 113029839 A includes a worktable. The four corners of the bottom outer wall of the worktable are fixedly connected to fixing pads. The two sides of the top outer wall of the worktable are fixedly connected to support plates. The top outer wall of the support plates is fixedly connected to a top plate. The top plate has a convex groove. A rotating motor is fixedly connected to the inner wall of the protruding end of the convex groove. A threaded screw is rotatably connected to the outer wall of one side of the rotating motor. A rotating shaft is fixedly connected to one end of the threaded screw. The rotating shaft is connected to the inner wall of one end of the convex groove by bolts. A fixing plate is rotatably connected to the outer wall of the threaded screw. Limiting plates are fixedly connected to the outer walls of both ends of the fixing plate.

[0005] The aforementioned invention enables the diamond drill bit to maintain a constant speed and pressure by rotating the motor, lead screw, and hydraulic rod, leaving scratches on the mineral surface and making the hardness measurement more accurate. Furthermore, the device can stably clamp minerals of different volumes and shapes, improving its applicability. However, for testing materials with different hardness levels, it is still necessary to manually change to different specifications of Mohs pens.

[0006] Based on the above reasons, this application proposes an automatic Mohs hardness testing device to improve the convenience of conducting Mohs hardness tests. Utility Model Content

[0007] Based on this, it is necessary to provide an automatic Mohs hardness testing device to address the aforementioned technical problems. A product clamping mechanism is installed at the bottom inner side of the support structure to clamp and position the product to be tested, while a Mohs pen storage mechanism is installed at the top inner side of the support structure to store the Mohs pen. During testing, the pen retrieval mechanism retrieves the corresponding model of Mohs pen from the storage mechanism according to settings and clamps it through a pen-drawing mechanism. Then, the pen-drawing mechanism is driven horizontally by a power source, causing the tip of the Mohs pen to draw across the outer surface of the product to be tested, thus performing the Mohs hardness test. The entire testing process requires no human intervention, and the pen-drawing mechanism can maintain a uniform and stable movement, while the pressure provided by the product clamping mechanism can also remain stable, achieving a stable testing structure and a convenient testing process.

[0031] By setting a telescopic drive unit at the bottom of the support platform, during testing, the telescopic drive unit applies upward pressure to the support platform, causing the end of the product under test to come into contact with the end of the Morse code pen, thereby allowing different pressures to be obtained between the outer surface of the product under test and the Morse code pen according to the testing requirements.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0049] As described in the background section, current testing methods all involve manually retrieving the pen. However, variations in pressure applied during these tests can easily lead to inaccurate results. Furthermore, having to retrieve the pen from a specific area for each test is time-consuming and inconvenient.

[0050] To solve this technical problem, this utility model provides an automatic Mohs hardness testing device, which is used to test the Mohs hardness of objects.

[0051] For details, please refer to Figures 1-2 The automatic Mohs hardness testing equipment specifically includes:

[0052] Support mechanism 1, which can support the entire device;

[0053] Product clamping mechanism 2 is located at the inner bottom of support mechanism 1. Product clamping mechanism 2 can clamp and position the product to be tested, and can drive the product to be tested to rise and fall.

[0054] The Morse pen storage mechanism 3 is located on the inner top of the support mechanism 1. The Morse pen storage mechanism 3 stores Morse pens 6 in batches for use during testing.

[0055] The pen-drawing mechanism 4 is located above the product clamping mechanism 2 and can clamp the Morse pen 6.

[0056] The pen-retrieving mechanism 5 is located between the Morse pen storage mechanism 3 and the pen-drawing mechanism 4. The pen-retrieving mechanism 5 can take out the Morse pen 6 from inside the Morse pen storage mechanism 3 and install the Morse pen 6 in the pen-drawing mechanism 4.

[0057] The pen-drawing mechanism 4 can move left and right to drive the Mohs pen 6 to draw on the outer surface of the product to be tested, thereby realizing the Mohs hardness test.

[0058] The automatic Mohs hardness testing device provided by this utility model has a product clamping mechanism 2 set at the bottom inner side of the support mechanism 1 to clamp and position the product to be tested, and a Mohs pen storage mechanism 3 set at the top inner side of the support mechanism 1 to store the Mohs pen 6. During testing, the pen retrieval mechanism 5 retrieves the corresponding model of Mohs pen 6 from the Mohs pen storage mechanism 3 according to the settings and clamps it through the pen drawing mechanism 4. Then, the pen drawing mechanism 4 is driven by power to move horizontally, so that the end of the Mohs pen 6 can draw on the outer surface of the product to be tested to perform the Mohs hardness test. The entire testing process does not require human intervention, and the pen drawing mechanism 4 can maintain a uniform and stable movement, achieving the effect of stable testing structure and convenient testing process.

[0059] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0060] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0061] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0062] Example 1

[0063] Please refer to Figures 1-3 and Figure 7 An automatic Mohs hardness testing device includes a support mechanism 1, a product clamping mechanism 2, a Mohs pen storage mechanism 3, a pen marking mechanism 4, and a pen retrieval mechanism 5. The support mechanism 1 supports the entire device. The product clamping mechanism 2 is located at the inner bottom of the support mechanism 1, and can clamp and position the product to be tested. It can also move the product to be tested up and down to change the testing pressure on the outer surface of the product. The Mohs pen storage mechanism 3 is located at the inner top of the support mechanism 1, and stores a batch of Mohs pens 6 for use during testing. The Mohs hardness test is divided into ten levels. Therefore, the configured Mohs pens 6 need to correspond to these ten levels. The pen marking mechanism 4 is located above the product clamping mechanism 2, and can clamp the Mohs pens 6. When the Mohs pen 6 is in contact with the product to be tested, the pen marking mechanism 4 can move left and right to move the Mohs pen 6 to scratch on the outer surface of the product to achieve the Mohs hardness test. The pen-retrieving mechanism 5 is located between the Morse pen storage mechanism 3 and the pen-drawing mechanism 4. The pen-retrieving mechanism 5 can retrieve the Morse pen 6 from inside the Morse pen storage mechanism 3 and install the Morse pen 6 in the pen-drawing mechanism 4. After the Morse pens 6 are placed in sequence, the pen-retrieving mechanism 5 can retrieve the corresponding Morse pen 6 according to the settings and place it in the pen-drawing mechanism 4 for clamping and drawing on the outer surface of the object to be tested.

[0064] Please refer to Figures 4-5 The product clamping mechanism 2 includes a support platform 201, with a limiting groove 202 on the top of the support platform 201. Symmetrically mounted, left and right, are horizontally movable product clamping sliders 203. These sliders can be driven pneumatically, hydraulically, or magnetically, and the limiting groove 202 adapts to the driving method of the product clamping sliders 203. When the product clamping sliders 203 are driven, the two sides of the product clamping sliders 203 can move relative to each other to clamp the product under test, ensuring the stability of the object being tested.

[0065] If the object to be tested is simply fixed in place, the pressure exerted by the pen mechanism 4 driving the Morse code pen 6 will be relatively small, often resulting in invalid test results. Therefore, a telescopic drive unit 204 is provided at the bottom of the support platform 201, which can drive the support platform 201 to move up and down. By pushing the object to be tested upwards, the pressure between the object and the Morse code pen 6 is increased, allowing the Morse code pen 6 to effectively test the outer surface of the object. The telescopic drive unit 204 is a device such as a telescopic cylinder that can extend and retract quantitatively.

[0066] Example 2

[0067] The automatic Mohs hardness testing equipment provided in Example 1 has been further optimized, specifically, as follows: Figure 7 As shown, the Morse pen storage mechanism 3 includes a support plate 301, and Morse pen clamping parts 302 are equidistantly arranged on the front side of the support plate 301. The Morse pen clamping parts 302 can clamp the Morse pen 6.

[0068] Through the above structural design, the Morse pen clamping part 302, which has elasticity and an opening, is used to clamp and limit the Morse pen 6. Therefore, after the pen-retrieving mechanism 5 clamps the Morse pen 6, only outward force needs to be applied to detach the Morse pen 6 from the inside of the Morse pen clamping part 302, improving the convenience of retrieving the Morse pen 6. When it is necessary to place the Morse pen 6, the pen-retrieving mechanism 5 applies pressure towards the Morse pen clamping part 302 after clamping the Morse pen 6. This causes the opening of the Morse pen clamping part 302 to open under elasticity, clamping and limiting the Morse pen 6, further improving the convenience of placing the Morse pen 6.

[0069] Example 3

[0070] The automatic Mohs hardness testing equipment provided in Example 1 or 2 has been further optimized, such as... Figure 1 and Figure 6As shown, the pen-drawing mechanism 4 includes a support slide rod 401, and the outer surface of the support slide rod 401 is provided with a first clamping block 402 and a second clamping block 403 that can move horizontally relative to each other. The moving directions of the first clamping block 402 and the second clamping block 403 are opposite, and the first clamping block 402 and the second clamping block 403 can be driven by a shaftless cylinder, a linear motor, etc. When clamping the Mohs pen 6, the first clamping block 402 and the second clamping block 403 move towards the center simultaneously to apply clamping pressure to the Mohs pen 6. A Mohs pen limiting groove 404 is provided on the side of the first clamping block 402 facing the second clamping block 403. When the Mohs pen 6 is placed inside the Mohs pen limiting groove 404, it can prevent the Mohs pen 6 from rolling and shifting after being subjected to force. This can effectively improve the accuracy of the Mohs hardness test. In order to prevent the Mohs pen 6 from slipping off while the pen-removing mechanism 5 is releasing the Mohs pen 6 and the first clamping block 402 and the second clamping block 403 have not fully clamped the Mohs pen 6. The inside of the Morse pen limiting groove 404 is provided with a magnetic block 405, which can magnetically attract the Morse pen 6, thereby making the Morse pen 6 stable in the initial stage of being fixed.

[0071] To further enhance the stability of the Morse code pen 6's strokes and its clamping stability, both the first clamping block 402 and the second clamping block 403 have 45-degree angled surfaces facing each other, which can fit together. This 45-degree angled support effectively counteracts gravity, preventing the Morse code pen 6 from falling quickly during initial clamping. Furthermore, when the object being tested rises and applies pressure to the end of the Morse code pen 6, the 45-degree angle effectively resists the pressure, preventing it from shifting upwards.

[0072] Example 4

[0073] The automatic Mohs hardness testing equipment provided in Example 1 has been further optimized, such as... Figures 2-3 As shown, the pen-grabbing mechanism 5 includes a horizontal guide rail 501, and a horizontally movable shaftless cylinder slider 502 is provided on the outer surface of the horizontal guide rail 501. The horizontal guide rail 501 and the shaftless cylinder slider 502 can be shaftless cylinders, etc., as long as they can drive the shaftless cylinder slider 502 to perform precise horizontal movement. A robotic arm 503 is provided on the side of the shaftless cylinder slider 502. The robotic arm 503 is rotatable, and its end is provided with a retractable gripper. The robotic arm 503 is an outsourced component and has no specific model; it only needs to be able to achieve rotation, extension, and gripping functions.

[0074] Through the above technical solution, the shaftless cylinder slider 502 drives the robotic arm 503 to a designated position, and then the claw at the end of the robotic arm 503 extends to the designated position of the Morse code pen 6 to grip it. Then, the shaftless cylinder slider 502 drives the robotic arm 503 between the first clamping block 402 and the second clamping block 403, and the rotation of the robotic arm 503 places the Morse code pen 6 between the first clamping block 402 and the second clamping block 403 to be clamped and fixed.

[0075] After the test is completed, the shaftless cylinder slider 502 and the robotic arm 503 operate in reverse to remove the Morse code pen 6 from between the first clamping block 402 and the second clamping block 403 and place it in the Morse code pen clamping part 302. This achieves the effect of automating the picking up and dropping of the Morse code pen 6 for testing.

[0076] The automatic Mohs hardness testing equipment provided in the above embodiments can be further optimized, such as... Figure 1 , Figures 6-7 As shown, the Mohs pen 6 includes a Mohs pen body 601, and the end of the Mohs pen body 601 is inlaid with a mineral corresponding to the Mohs hardness test level as a test head.

[0077] To further enhance the stability of the Morse code pen body 601 during installation, a locking hole 602 is provided on the Morse code pen body 601. A sliding pin 406, adapted to the locking hole 602, is provided on the side of the second clamping block 403 facing the first clamping block 402. When the Morse code pen body 601 is fixedly clamped, the sliding pin 406 inserts into the locking hole 602, providing a unique orientation and position for the Morse code pen body 601, thus improving the accuracy of the Morse code pen body 601 installation.

[0078] It should be noted that there are ten Mohs hardness 601 pencil bodies, and the hardness of the ten Mohs hardness 601 pencil bodies corresponds to the ten levels of the Mohs hardness test.

[0079] The usage process of the automatic Mohs hardness testing device provided by this utility model is as follows:

[0080] The product to be tested is placed between two product clamping sliders 203 on the top of the support platform 201, and the two product clamping sliders 203 are driven to clamp and fix the product to be tested.

[0081] The movement of the shaftless cylinder slider 502 is driven by an external host computer, so that the shaftless cylinder slider 502 drives the robotic arm 503 to move to the designated position.

[0082] Once the robotic arm 503 reaches the designated position, it uses rotation, extension and retraction to grip the required Morse code 6.

[0083] When the robotic arm 503 picks up the Morse pen 6, it moves the Morse pen 6 between the first clamping block 402 and the second clamping block 403, and places the Morse pen 6 inside the Morse pen limiting groove 404, and is attracted by the magnetic block 405.

[0084] By driving the first clamping block 402 and the second clamping block 403 to move closer to the Morse pen 6, a clamping force is formed on the Morse pen 6 to ensure that the Morse pen 6 remains stable.

[0085] The telescopic drive unit 204 drives the limiting slide 202 to rise, so that the top of the product under test comes into contact with the end of the Morse pen 6.

[0086] By simultaneously driving the first clamping block 402 and the second clamping block 403 to move in the same direction, the Mohs pen 6 is driven to scratch on the outer surface of the object to be tested, thereby achieving precise Mohs hardness measurement.

[0087] After the test is completed, the telescopic drive unit 204 drives the support platform 201 to fall and drives the product clamping slider 203 to release the product to be tested.

[0088] At this time, the first clamping block 402 and the second clamping block 403 return to the initial middle position, and the shaftless cylinder slider 502 drives the robotic arm 503 to above the Morse pen 6. While the first clamping block 402 and the second clamping block 403 release the Morse pen 6, the robotic arm 503 clamps the Morse pen 6.

[0089] The shaftless cylinder slider 502 is driven to move the robotic arm 503 to the position to pick up the Morse code 6, and fix the Morse code 6 in the corresponding Morse code holder 302 for the next use.
