Technical Field

[0001] This application relates to the field of testing instrument technology, and more specifically, to a testing device. Background Technology

[0002] In modern manufacturing, many products, such as the casings and displays of electronic products, automotive interior parts, and various plastic products, may come into contact with alcohol-based cleaners or disinfectants during daily use. Therefore, testing the alcohol stress resistance of products becomes crucial.

[0003] Currently, some companies still use traditional manual testing methods to test product alcohol stress resistance. For example, they manually wipe the product surface with an alcohol-soaked cloth and then observe for discoloration, deformation, peeling, or other damage. However, this manual testing method has many drawbacks. Firstly, manual operation makes it difficult to ensure consistency in testing conditions such as the wiping force, number of wipes, and amount of alcohol used each time, resulting in poor accuracy and repeatability of the test results. Secondly, manual testing is inefficient, requiring significant manpower and time for testing large batches of products. Summary of the Invention

The first limiting member and the second limiting member are arranged opposite to each other along the second direction, thereby restricting the movement of the product along the second direction.

[0011] In a further preferred embodiment, the first limiting member is disposed at the end of the first smooth section near the end of the arc-shaped section, and the second limiting member is disposed at the end of the second smooth section near the end of the arc-shaped section.

[0012] Further preferably, the clamping assembly includes: a clamping arm and a clamping protrusion slidably mounted on the clamping arm, the clamping arm rotating about a rotation center, such that the clamping arm drives the clamping protrusion to switch between a first working state and a second working state, the first working state being that the clamping protrusion is far away from the product, and the second working state being that the clamping protrusion is close to the product.

[0013] Further preferably, the clamping arm includes a mounting groove, which is provided along the extending direction of the clamping arm. The clamping protrusion is fixed on the rod, which passes through the mounting groove and slides back and forth along the mounting groove.

Detailed Implementation

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] This application provides a testing device 1 for testing the alcohol resistance stress of a product. The specific structure of the testing device 1 is as follows: Figure 1 As shown, the product tested by the testing device 1 is a sample bar. The material of the sample bar is PMMA (polymethyl methacrylate), and the yield strain parameter of the sample bar is 0.63%.

[0028] In some embodiments, the detection device 1 includes a fixing component 10 and a clamping component 20, the clamping component 20 being mounted on the fixing component 10; the fixing component 10 includes a first smooth section 11, an arc-shaped section 13, and a second smooth section 12, the first smooth section 11, the arc-shaped section 13, and the second smooth section 12 being connected in sequence, the first smooth section 11 and the second smooth section 12 having the same height in a first direction Q, and the arc-shaped section 13 being higher than the first smooth section 11 and the second smooth section 12 in the first direction Q; the clamping components 20 are arranged in pairs and are respectively mounted on the first smooth section 11 and the second smooth section 12, the paired clamping components 20 fixing the product from both ends, the clamping components 20 being adapted to restrict the movement of the product, wherein the first direction Q is the height direction of the detection device 1.

[0029] In some embodiments, during the process of manually testing the alcohol resistance of a product, it is necessary to maintain a certain wiping force, number of tests, and amount of alcohol. Repeated labor can cause fatigue in the testing personnel and easily lead to operational errors during the testing process, affecting the final test results. Therefore, the testing device 1 can replace manual testing and maintain the accuracy of the testing process after repeated labor.

[0030] In some embodiments, such as Figure 2 As shown, the fixed component 10 is provided with an arc-shaped segment 13. On the one hand, it can be adapted to some products with arc-shaped structures. On the other hand, it can restore the actual stress distribution of the product. In practical applications, many products will have stress concentration in certain parts due to their structural characteristics. The arc-shaped segment 13 can simulate the areas and situations where stress concentration occurs in the actual use of the product, making the testing environment closer to the actual working conditions of the product, and making the test results more reliable.

[0031] In some embodiments, such as Figure 1 As shown, the clamping components 20 are arranged in pairs and are respectively installed on the first smooth section 11 and the second smooth section 12. They are fixed from both ends of the product, which can effectively restrict the movement of the product. Whether in the process of testing the product's alcohol resistance stress or in the process of handling and operating the testing device 1, the product can be kept in a fixed position to prevent deviations in the test data due to shaking or displacement, thus ensuring the reliability of the test results. At the same time, fixing the product from both ends makes the force on the product more uniform.

[0032] In some embodiments, the arc segment 13 includes: a stop 131, the stop 131 being arranged in pairs and spaced apart along a second direction P to define an installation space 131a, the installation space 131a being adapted to install a product.

[0033] In some embodiments, such as Figure 2 As shown, the paired stop members 131 are arranged at intervals along the second direction P, which can accurately define the installation space 131a, so that the product installation position is accurate and it is convenient for operators to install the product; the stop members 131 can fix and limit the product, prevent the product from moving or shaking during the testing process, and enhance the stability and reliability of the testing device 1.

[0034] In some embodiments, the arc segment 13 has an arc surface, the stop member 131 is provided to protrude relative to the arc surface, and the stop member 131 extends along the second direction P.

[0035] In some embodiments, such as Figure 2 As shown, the stop member 131 protrudes relative to the arc-shaped surface. When the product is placed in the installation space 131a, the stop member 131 can abut against the side of the product, thereby restricting the product from shifting. The stop member 131 extends along the second direction P, further increasing the contact area between the stop member 131 and the product.

[0036] In some embodiments, such as Figure 4 Furthermore, this application also provides another fixing component 10, wherein the stop 131 may be a small protrusion, distinct from... Figure 2 Stop 131 of the middle strip, Figure 4 The stop 131 shown has a smaller contact area with the product, which reduces the restrictions on the product shape and makes it applicable to the inspection of more product models, thus making the inspection device 1 more practical.

[0037] In some embodiments, the fixing component 10 is provided with multiple sets of clamping components 20, the number of clamping components 20 being twice the number of mounting spaces 131a, so that the clamping components 20 can fix the product from both ends of the product, thereby restricting the movement of the product.

[0038] In some embodiments, the diameter of the arc segment 13 is R, and the value of R is within the range of 10cm≤R≤15cm.

[0039] In some embodiments, a larger diameter R of the arc segment 13 will result in a more uniform stress distribution in the product, avoiding stress concentration and preventing product deformation. The diameter R of the arc segment 13 can be in the range of 10cm≤R≤15cm, specifically: 10cm, 10.5cm, 11cm, 11.5cm, 11.75cm, 12cm, 12.15cm, 12.5cm, 12.75cm, 13cm, 13.15cm, 13.44cm, 13.75cm, 14cm, 14.15cm, 14.3cm, 14.44cm, 14.77cm, 15cm.

[0040] In some embodiments, the fixing component 10 is made of engineering plastic or stainless steel.

[0041] In some embodiments, the fixing component 10 is used to fix the product. During the process of testing the product's resistance to alcohol stress, alcohol needs to be dripped onto the product. The alcohol may flow onto the surface of the fixing component 10. In order to prevent the fixing component 10 from being corroded by alcohol during long-term use, the fixing component 10 needs to be made of a corrosion-resistant material, such as engineering plastics or stainless steel. If engineering plastics are chosen to process the fixing component 10, polytetrafluoroethylene (PTFE) or polyetheretherketone (PEEK) can be selected. They have excellent chemical stability, hardly react with alcohol, can resist alcohol corrosion well, and have a longer service life. Moreover, the processing technology is simple, and complex-shaped fixing components 10 can be quickly manufactured by injection molding, compression molding and other methods, with high production efficiency and relatively low cost.

[0042] In some embodiments, if stainless steel is selected for processing, stainless steel has good corrosion resistance, high strength, good toughness, can meet the mechanical performance requirements of the fixing component 10, is not easy to deform and break, and is easy to process and form. It can be made into fixing components 10 of various shapes and sizes as needed, and has a high surface finish, so no polishing is required.

[0043] In some embodiments, a first limiting member 111 is provided on the first smooth section 11, and a second limiting member 121 is provided on the second smooth section 12. The first limiting member 111 and the second limiting member 121 are arranged opposite to each other along the second direction P, thereby restricting the movement of the product along the second direction P.

[0044] In some embodiments, by providing relative first limiting members 111 and second limiting members 121 in the first smooth section 11 and the second smooth section 12 respectively, the movement of the product along the second direction P can be precisely limited, so that the product is in an accurate position after installation, ensuring the consistency and stability of product installation, which is beneficial to improving the assembly quality and performance of the product. The second direction P is the length direction of the fixing component 10.

[0045] In some embodiments, the first limiting member 111 is disposed at the end of the first smooth section 11 near the end of the arc-shaped section 13, and the second limiting member 121 is disposed at the end of the second smooth section 12 near the end of the arc-shaped section 13.

[0046] In some embodiments, when the product is to fit against the arc segment 13, the product will undergo a certain degree of elastic deformation, thereby simulating the stress concentration problem during product use. When the product undergoes elastic deformation, both ends of the product can contact the first limiting member 111 and the second limiting member 121. The two limiting members can cooperate with each other to keep the product in its current deformed state. If the first limiting member 111 and the second limiting member 121 are not provided near the end of the arc segment 13, it is difficult to keep the product in its deformed state, which will cause the product to fail to fit against the arc segment 13, which may cause the product to fall off and affect the stability of the detection device 1.

[0047] In some embodiments, the clamping assembly 20 includes a clamping arm 21 and a clamping protrusion 22 slidably mounted on the clamping arm 21. The clamping arm 21 rotates about a rotation center, causing the clamping arm 21 to drive the clamping protrusion 22 to switch between a first working state and a second working state. The first working state is in which the clamping protrusion 22 moves away from the product, and the second working state is in which the clamping protrusion 22 abuts against the product.

[0048] In some embodiments, such as Figure 3 As shown, the clamping assembly 20 includes a clamping arm 21 and a clamping protrusion 22. The clamping arm 21 is rotatable, thereby causing the clamping protrusion 22 to come into contact with or move away from the product, so as to switch between a first working state and a second working state. In the second working state, the clamping protrusion 22 approaches the arc surface of the arc segment 13, thereby clamping one end of the product.

[0049] In some embodiments, the clamping protrusion 22 is made of rubber, which increases the friction between the product and the clamping protrusion 22 during the clamping process, preventing relative sliding between the product and the clamping protrusion 22. On the other hand, the two elastically abut against each other, preventing excessive clamping force from causing product damage.

[0050] In some embodiments, the clamping arm 21 includes a mounting groove 211, which is provided along the extending direction of the clamping arm 21. The clamping protrusion 22 is fixed on the rod 23, which passes through the mounting groove 211 and slides back and forth along the mounting groove 211.

[0051] In some embodiments, such as Figure 3As shown, the clamping arm 21 is provided with a mounting groove 211. The extending direction of the mounting groove 211 is consistent with the extending direction of the clamping arm 21. The clamping protrusion 22 is fixed on the rod 23. The rod 23 passes through the mounting groove 211 and can slide along the mounting groove 211, so that the clamping assembly 20 can flexibly adjust the position of the clamping protrusion 22 to adapt to products of different thicknesses and improve the versatility of the clamping assembly 20.

[0052] In some embodiments, the rod 23 is threaded on the outside, and the clamping arm 21 has nuts on both sides. The nuts engage with the threads of the rod 23, and the nuts are adapted to adjust the length of the rod 23 extending relative to the first surface 212 of the clamping arm 21.

[0053] In some embodiments, the length of the rod 23 extending relative to the first surface 212 of the clamping arm 21 can be precisely controlled by the engagement of the nut with the thread on the rod 23. When the nut is rotated, the rod 23 will move precisely according to the lead of the thread, which can meet the clamping requirements of products of different thicknesses. The position of the clamping protrusion 22 can be accurately adjusted to achieve tight and stable clamping. The adjustment method is also simpler, as it can be adjusted by simply rotating the nut.

[0054] In some embodiments, the nut and the threaded engagement of the rod 23 provide a reliable fixing effect. When the rod 23 is adjusted to a suitable extension length, the nut can securely lock it in that position, preventing the rod 23 from moving unexpectedly due to external forces during clamping, thus ensuring the stability and reliability of clamping.

[0055] During the alcohol resistance stress test, the product is first placed in the installation space 131a, with the stop 131 abutting against the two sides of the product to limit its displacement. During placement, the product undergoes elastic deformation, causing it to conform to the curved surface, thus simulating stress concentration during actual use. The two ends of the product abut against the first limiting member 111 and the second limiting member 121, respectively, allowing the product to maintain its bent shape and restricting its movement to prevent it from leaving the installation space 131a, thereby increasing the stability of the testing device 1 during use. The clamping assembly 20 is equipped with a handle 24. When the operator pulls the handle 24, the clamping arm 21 rotates, causing the clamping protrusion 22 to abut against the product. The clamping protrusion 22 then approaches the curved surface, clamping the product and limiting its vertical movement. After the test is completed, the operator pulls the handle 24 again, causing the clamping protrusion 22 to move away from the product, allowing the product to be removed.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
