Technical Field

[0001] This utility model belongs to the field of impact testing technology, and relates to a mechanical impact testing device with temperature regulation. Background Technology

[0002] Polycrystalline solid materials are widely used in integrated circuits, and their mechanical properties directly affect chip manufacturing yield and the lifespan of the final product. Mechanical strength testing is an indispensable part of the process for polycrystalline solid materials in integrated circuits. It runs through the entire process from material research and development and production process optimization to final quality control, and is the cornerstone of ensuring that the chip can withstand various stresses in subsequent manufacturing processes and operate stably in various application scenarios. Meanwhile, microcrystalline panels made of polycrystalline solid materials also have wide applications in production, such as induction cooker panels and electric stoves. The central area is the main heating zone and also the most vulnerable part to mechanical impact. Microcrystalline panels need to undergo rigorous impact testing before leaving the factory to ensure that they can withstand a certain intensity of mechanical impact in actual use. Currently, existing technologies lack devices specifically designed for repeated impact testing of the heating areas of these materials. Most tests are done manually, resulting in low testing efficiency, inaccurate impact height, and unreliable results. Therefore, there is an urgent need for a highly automated testing device capable of repeated impact testing. Summary of the Invention

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0015] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. 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.

[0016] Figure 1 , 2 The system includes a temperature chamber 10, a temperature chamber door 11, an observation window 12, a parameter setting touch screen 13, a power switch 14, a sample clamp 20, a contour block 21, a container 22, a motion mechanism 30, a traction line 31, a sliding roller 32, a motion rod 33, a guide roller 34, an acceleration cylinder 35, a motion mechanism bracket 36, a braided belt clamping mechanism 40, a braided belt clamping seat 41, a clamping pressure plate 42, a manual tightening screw 43, a proximity switch 50, and a braided belt 60, etc.

[0017] like Figure 1 , 2 As shown, this utility model aims to overcome the shortcomings of the prior art and provide a mechanical impact testing device with temperature regulation to solve the problem of difficult automated and repeatable impact testing of polycrystalline solid materials such as microcrystalline panels. This device can conveniently and quickly perform repeated impact tests on specific areas (such as the heat-generating center area) of a sample (such as a microcrystalline panel), and the test results are accurate and reliable.

[0018] like Figure 1 , 2 As shown, the mechanical impact testing device with temperature regulation described in this utility model comprises a temperature chamber 10, a motion mechanism 30, a braided strap clamping mechanism 40, a sample holder 20, and a control system. The control system is an automated control core built on a programmable logic controller (PLC) or a microcontroller (such as an ARM Cortex-M series chip), designed to precisely and automatically execute the impact testing process. It is understood that the temperature chamber 10 is a mature product in the prior art, capable of simulating high and low temperature environments and possessing temperature regulation capabilities to meet testing needs under various temperature conditions.

[0019] The temperature chamber 10 constitutes the main testing environment. It has a temperature chamber door 11 that rotates via a hinge, and an observation window 12 is installed on the door to facilitate real-time observation of the testing process inside the chamber. The panel of the temperature chamber 10 integrates a parameter setting touch screen 13 and a power switch 14, which are used to set parameters such as the number of impacts and the test temperature, and to control the power supply of the equipment. This is the key to realizing human-machine interaction and automated control.

[0020] A motion mechanism 30 is installed on the top of the temperature chamber 10. This mechanism is the core of the "rapid descent" impact function and mainly includes a motion mechanism support 36, a motion rod 33, an acceleration cylinder 35, guide rollers 34, and sliding rollers 32. The acceleration cylinder 35, as a power source, can be installed on the motion mechanism support 36 or on the top of the temperature chamber 10, flexibly arranged according to actual space requirements. The acceleration cylinder 35 is connected to an external air source via an air pipe and is controlled by a solenoid valve integrated in the control system. When the solenoid valve is energized, the cylinder moves rapidly, driving the motion rod 33 to move. The motion rod 33 is constrained between two sets of guide rollers 34 and is driven by the acceleration cylinder 35 to perform precise and stable reciprocating movement. One end of the motion rod 33 is connected to a traction line 31, and the other end of the traction line 31 passes through the top plate of the temperature chamber 10, extends into the chamber, and connects to the braided strap clamping mechanism 40.

[0021] The braided strap clamping mechanism 40 is used to reliably clamp and fix the braided strap 60. Specifically, the braided strap clamping mechanism 40 includes a braided strap clamping seat 41, a clamping pressure plate 42, and a manual tightening screw 43. By rotating the manual tightening screw 43, the clamping pressure plate 42 can be firmly pressed onto the braided strap clamping seat 41, thereby clamping and fixing one end of the braided strap 60. As an optimized design, the body of the braided strap clamping mechanism 40 can be constructed in a triangular shape, with a braided strap clamping seat 41 on each of its three inclined surfaces. Each seat is equipped with a set of pressure plates 42 and manual tightening screws 43. This allows two of the clamping seats to clamp the lower ends of the two braided straps 60 respectively, and the lower ends of the two braided straps 60 are respectively connected to the corresponding lifting lugs on the top surface of the container 22. This dual-point suspension design ensures the balance and stability of the container 22 during the impact process.

[0022] A container 22 is suspended from the lower end of the braided belt 60. The container 22 is filled with sand or granules, and its total mass is precisely adjusted to (1.80±0.01) kg to meet the standard test requirements.

[0023] The temperature chamber 10 is equipped with a sample holder 20 for fixing samples such as microcrystalline panels to be tested. In order to accurately control the impact height, a height equalization block 21 is placed on the sample held in the sample holder 20. In the initial state, the container 22 is placed on the height equalization block 21, thereby accurately positioning the initial impact height from its bottom to the sample surface as 150mm.

[0024] A proximity switch 50 is also installed on the top of the temperature chamber 10. The proximity switch 50 is electrically connected to a control system to detect the position of the moving rod 33 of the motion mechanism 30 in real time and feed it back to the control system to control the number of impacts and reset. This signal, combined with the control system in the parameter setting touch screen 13, ensures the accuracy and repeatability of the impact height and realizes automatic counting of multiple impacts.

[0025] The proximity switch 50 (which can be inductive or photoelectric) is electrically connected to the PLC or microcontroller control system integrated in the parameter setting touch screen 13. When the moving lever 33 moves to the release position, the proximity switch 50 generates a signal, which is recorded by the control system. This signal is used to confirm the completion of an impact action and to count it, and also to compare it with the set parameters to ensure that the initial height of each impact is consistent.

[0026] The control system is the core of the automated testing system, and it uses a programmable logic controller (PLC) or a microcontroller as the core control unit. This control system is electrically connected to the parameter setting touchscreen display 13, the proximity switch 50, and the solenoid valve that controls the acceleration cylinder 35.

[0027] Initialization and parameter setting: The operator sets the number of impacts (e.g., 10 times) and test temperature required for this test through the parameter setting touch screen 13.

[0028] Preparation complete: Place the sample holder 20 containing the sample into the temperature chamber 10, and use the leveling block 21 to precisely position the initial height of the container 22. After completion, remove the leveling block 21, and the container 22 is suspended by the traction line 31.

[0029] Start-up test: The operator initiates the test program via the touchscreen. The control system first drives the acceleration cylinder 35 to reset the motion lever 33 to its initial position, which is detected and confirmed by the proximity switch 50.

[0030] Impact cycle: a. The control system sends a command to the solenoid valve to accelerate the cylinder 35 to move rapidly, drive the motion rod 33 to move, and instantly release the constraint on the traction line 31, so as to realize the free fall impact of the container 22.

[0031] b. After the impact, the moving rod 33 moves to another position under the drive of the cylinder, and this action is detected by the proximity switch 50. The control system records this signal as a valid impact and updates the impact count.

[0032] c. Subsequently, the control system drives the cylinder to reset the moving rod 33, preparing for the next impact.

[0033] Cycle termination: The control system compares the current number of impacts with the set value. If the set value is not reached, step 4 is repeated; if the set value is reached, the test is terminated, and the operator is notified via the touchscreen.

[0034] The workflow and beneficial effects of this utility model are as follows: During testing, the sample holder 20 containing the sample is first placed in the temperature chamber 10, and the initial height of the container 22 is precisely positioned at 150mm using the leveling block 21. The required number of impacts (e.g., 10 times) is set via the parameter setting touch screen 13. After preparation, the leveling block 21 is removed, at which point the container 22 is completely suspended by the traction line 31 and the braided strap clamping mechanism 40.

[0035] After the test program is started, the acceleration cylinder 35 moves rapidly, driving the motion rod 33 to move, thereby instantly releasing the constraint on the traction line 31 and realizing the "rapid descent" of the container 22—that is, free fall motion—precisely impacting the designated area of ​​the sample on the sample holder 20. The proximity switch 50 and the control system ensure that the initial height of each impact is consistent. After one impact is completed, the motion mechanism 30 can automatically reset to prepare for the next impact, until the set number of impacts is completed.

[0036] This invention, through the aforementioned structure, achieves automated testing of impact height with high accuracy and repeatability, improving testing efficiency and reliability. The braided strap clamping mechanism ensures suspension stability, while the overall integrated design makes operation convenient and suitable for impact performance testing of various polycrystalline solid materials such as microcrystalline panels.

[0037] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
