[0002] During product transportation, various environmental and physical stresses can pose potential threats to the product, potentially causing damage upon arrival at the end user. For example, a large silicon wafer, if improperly packaged, may break during long-distance transport due to vibration, drops, or compression, affecting its integrity and performance. Similarly, solder preforms may develop micro-scratches due to continuous vibration during transportation. Friction between these micro-scratches and the packaging material can lead to performance degradation or even complete loss of function.

[0048] The following specific embodiments are given to illustrate the technical solution of this application in detail.

[0049] Figure 1 This is a schematic diagram of a transportation conditions simulator shown as an exemplary embodiment of this application. Figure 2 For this Figure 1 The diagram shows the simulator components in the transportation conditions simulator. Please also refer to... Figure 1 and Figure 2 The transportation condition simulator provided in this embodiment includes a simulator component 100, a sensor group 200, and a controller 300; the simulator component 100 includes a flight environment simulator 1, a ground environment simulator 2, and a temperature and humidity environment simulator 3. Figure 2 (not shown in the image); where,

[0050] The flight environment simulator 1 comprises a base 11, an elevator 12, a container 13, a first wing-shaped cantilever beam 14 and a second wing-shaped cantilever beam 15 arranged on two sides of the container 13 respectively, and a first engine 16 mounted on the first wing-shaped cantilever beam 14 and a second engine 17 mounted on the second wing-shaped cantilever beam 15; wherein one end of the elevator 12 is connected with the base 11 and the other end is connected with the container 13, for controlling the lifting of the container 13.

[0051] The container 13 has a wheel 131 at the bottom, and the base 11 has a groove 111; the ground environment simulator 2 comprises a cylindrical road simulator 21; the cylindrical road simulator 21 is arranged in the groove 111; the cylindrical road simulator 21 can rotate in the groove 111 with the wheel 131 running on it, to simulate the situation that the wheel 131 drives on the road with different degrees of bumpiness.

[0052] The temperature and humidity environment simulator 3 is used to provide a specified temperature environment and humidity environment for the container 13.

[0053] The controller 300 is used to control the simulator assembly 100 to simulate any actual transportation condition obtained in advance; wherein the actual transportation condition is a transportation condition described by a combination of mechanical movement, vibration, temperature and humidity.

[0054] The sensor group 200 is arranged inside the container 13, for measuring the simulated transportation environment simulated by the simulator assembly 100 in real time, and sending the simulated transportation environment to the controller 300.

[0055] The controller 300 is also used to adjust the simulator assembly 100 based on the simulated transportation environment and the actual transportation condition feedback, so as to match the simulated transportation environment with the actual transportation condition, to simulate the real transportation condition.

[0056] It should be noted that the transportation simulator provided by the present application is used to reproduce the transportation condition of the product in the transportation process. The product can be any product. Preferably, the product is a packaged precision product, which needs to maintain good integrity during transportation to avoid damage. By using the transportation condition simulator to simulate the actual transportation condition, the state of the product under different transportation conditions can be obtained, and then the packaging method, fixing method and transportation method of the product are optimized according to the obtained state, so as to effectively ensure that the product maintains good integrity and performance in various transportation environments.

[0057] Please refer to Figure 2The simulator component 100 includes a flight environment simulator 1, a ground environment simulator 2, and a temperature and humidity environment simulator 3. Figure 2 (Not shown in the image), wherein the flight environment simulator 1 includes a base 11, an elevator 12, a container 13, a first airfoil cantilever beam 14 and a second airfoil cantilever beam 15 respectively disposed on both sides of the container 13, and a first engine 16 mounted on the first airfoil cantilever beam 14 and a second engine 17 mounted on the second airfoil cantilever beam 15; wherein, one end of the elevator 12 is connected to the base 11 and the other end is connected to the container 13, and is used to control the lifting and lowering of the container 13.

[0058] It should be noted that the base 11 is the basic support component of the entire simulator assembly 100. The base 11 provides stable support for the elevator 12, which is mounted on the base 11. One end of the elevator 12 can be firmly connected to the connecting part on the base 11, ensuring that the elevator 12 will not loosen or move during its lifting and lowering process. The elevator 12 moves up and down under its own control, thereby controlling the up and down movement of the container 13 connected to the other end. The secure connection to the base 11 also prevents the container 13 from tilting unnecessarily during lifting and lowering, ensuring the accuracy of the simulation.

[0059] It should be noted that the transportation condition simulator provided in this application can simulate the take-off and landing of an aircraft, turbulence, and the handling process of products and the falling of products during the handling process by controlling the lifting of the elevator 12.

[0060] Specifically, for example, by precisely controlling the lifting speed and altitude changes of the elevator 12, the takeoff and landing process of an aircraft can be simulated. In practice, different lifting curves can be set, such as slow ascent and rapid descent, to simulate different types of flight operations. Furthermore, by setting random vibration frequencies and amplitudes, turbulence under different flight environments, such as unstable airflow, can be simulated. Additionally, for example, minute vibrations can be introduced to simulate the product handling process; furthermore, the elevator 12 can be suddenly lowered to simulate the product falling during handling.

[0061] Optionally, in one possible implementation, the lift 12 may be a hydraulic lift.

[0062] It should be noted that when the transport condition is simulated, the product to be tested is placed inside the container 13. The container 13 for placing the product to be tested has good heat insulation performance, and the container 13 is a sealed box. In this way, it can be ensured that the temperature environment inside the container 13 is relatively stable, and external substances enter the container 13, reducing the damage of external substances to the product to be tested, so as to simulate the protection of precision products in harsh environments during product transportation.

[0063] Please continue to refer to Figure 2 The two sides of the container 13 are also provided with a first wing-shaped cantilever beam 14 and a second wing-shaped cantilever beam 15, which are the same in size and shape, so that the flight environment simulator 1 remains balanced during simulation. When simulating the flight state, the container 13 is subjected to more uniform air forces.

[0064] It should be noted that the wing-shaped cantilever beam (the wing-shaped cantilever beam specifically refers to the first wing-shaped cantilever beam 14 and the second wing-shaped cantilever beam 15) is usually a single planar structure, and the cross section can be trapezoidal or rectangular; further, the upper surface of the wing-shaped cantilever beam can be smoother to reduce air resistance, and the lower surface can have a certain curvature to form lift. In addition, the wing-shaped cantilever beam is usually made of lightweight high-strength materials, such as carbon fiber or aluminum alloy, to improve strength and reduce weight.

[0065] Further, a first engine 16 is installed below the first wing-shaped cantilever beam 14, and a second engine 17 is installed below the second wing-shaped cantilever beam 15. In one possible implementation, the first engine 16 and the second engine 17 are the same, and two identical engines can ensure that the power and vibration generated by the engines are evenly applied to the container 13, so that the forces on the left and right sides of the container 13 in the forward direction are symmetrical and stable. In this way, the flight environment simulator 1 can simulate the force condition in a more realistic flight state.

[0066] It can be understood that the transport condition simulator can simulate different modes of vibration by controlling the speed of the first engine 16 and the second engine 17 or controlling the position of the engine on the wing-shaped cantilever beam.

[0067] It should be noted that in order to simulate different transport conditions, the speed of the engine and the position of the engine can be set according to actual needs, which are not limited herein. For example, when the speed of the engine is low, slight low-frequency vibration can be generated to simulate the slight shaking of the aircraft in a smooth driving state; when the speed of the engine is high, strong vibration can be generated to simulate the violent vibration of the aircraft during take-off, landing, or when subjected to strong air flow.

[0068] Further, by setting the engine close to the container 13, a local strong vibration effect can be simulated, or by moving the engine away from the container 13, a global vibration effect can be simulated. Figure 3 The schematic diagram of the position of the engine on the wing-shaped cantilever beam is shown in FIG. 1A of the drawings. Figure 3 , Figure 3 In FIG. 1A of the drawings, the engine is set close to the container 13, Figure 3 In FIG. 1B of the drawings, the engine is set away from the container 13, and by controlling the position of the engine on the wing-shaped cantilever beam, different modes of vibration can be simulated.

[0069] Further, please continue to refer to Figure 2 The bottom of the container 13 is also provided with a wheel 131, and the base 11 has a recess; the ground environment simulator 2 includes a cylindrical road simulator 21; and the cylindrical road simulator 21 is arranged in the recess.

[0070] Figure 4A The matching relationship diagram of the cylindrical road simulator and the wheel is shown in FIG. 4 of the drawings. Figure 4B The matching principle diagram of the cylindrical road simulator and the wheel is shown in FIG. 4 of the drawings. Please refer to FIG. 4, the cylindrical road simulator 21 can rotate in the recess while the wheel 131 runs thereon, so as to simulate the situation that the wheel 131 runs on a road with different bumping degrees.

[0071] Specifically, Figure 5 The schematic diagram of the cylindrical road simulator is shown in FIG. 4 of the drawings. Please refer to FIG. 4 and FIG. 5 of the drawings. Figure 5 The cylindrical road simulator 21 includes a plurality of sub-cylinders, and the plurality of sub-cylinders have different texture patterns for simulating roads with different bumping degrees. For example, in the example shown in FIG. 5, the cylindrical road simulator 21 is composed of six sub-cylinders, and each sub-cylinder contains different texture patterns. For example, in the example shown in FIG. 5, along the length direction of the recess 111, from left to right, the texture patterns on each sub-cylinder are smoother and smoother, and roads with different bumping degrees can be simulated in sequence. Figure 5 Figure 5

[0072] In the implementation, by lifting of the elevator 12, the wheel 131 can be in contact with the outer surface of a certain sub-cylinder in the cylindrical road simulator 21, that is, the wheel 131 can be placed on a certain sub-cylinder in the cylindrical road simulator 21, so as to simulate the product transportation on the road corresponding to the sub-cylinder.

[0073] Further, please refer to​​Figure 2 It can be understood that the length direction of the groove is consistent with the length direction of the cylindrical road simulator 21, which can move in the groove to make the wheel 131 opposite to different sub-cylinders to simulate the situation of driving on different road surfaces.

[0074] Specifically, after completing the simulation of transportation on a certain road surface, the wheel 131 can be first lifted by the elevator 12 to be away from the contact with the cylindrical road simulator 21, and then the cylindrical road simulator 21 is moved to make the sub-cylinder with the texture characteristics corresponding to the road surface to be simulated opposite to the bottom of the wheel 131, and the wheel 131 is moved to contact with the sub-cylinder by the elevator 12, and the simulation of the next kind of road surface is continued.

[0075] It can be understood that different texture characteristics can be set on the sub-cylinder according to the road surface to be simulated, which is not limited herein. For example, in an embodiment, when a flat highway road surface needs to be simulated, a sub-cylinder with relatively smooth texture characteristics can be set; in another embodiment, when a rugged mountain road needs to be simulated, a sub-cylinder with relatively rough and irregular texture characteristics can be set.

[0076] Further, the simulator assembly 100 further comprises a temperature and humidity environment simulator 3 for providing a specified temperature environment and humidity environment for the container 13.

[0077] Optionally, Figure 6 A partial schematic view of a simulator assembly according to an example embodiment of the present application is shown in Figure 6 In the example shown in Figure 6 The temperature and humidity environment simulator 3 is built-in in the container 13; the temperature and humidity environment simulator 3 comprises a heater, a cooler, a humidifier and a dehumidifier.

[0078] When the temperature inside the container 13 is adjusted by the heater or the cooler, the air flow inside the container 13 can make the temperature environment inside the container 13 evenly distributed, effectively avoiding the situation of local overheating or overcooling inside the container 13; similarly, when the humidity inside the container 13 is adjusted by the humidifier and the dehumidifier, the air flow inside the container 13 also helps the water to spread faster, achieving rapid humidity control.

[0079] Further, Figure 7 A partial schematic view of a simulator assembly according to another example embodiment of the present application is shown in Figure 7 In the example shown in Figure 7In the shown example, the temperature and humidity environment simulator 3 comprises an air supplier, and a heater, a cooler, a humidifier and a dehumidifier, wherein the air supplier is in communication with the container 13 through an air pipe; the heater, the cooler, the humidifier and the dehumidifier are used to control the temperature and humidity of the air supplied by the air supplier to the container 13.

[0080] Specifically, the air supplier is a temperature and humidity controlled air supplier, which is in communication with the container 13 through an air pipe to provide air to the inside of the container 13. In addition, the air provided by the air supplier to the container 13 is controlled in temperature by the heater and the cooler, and controlled in humidity by the humidifier and the dehumidifier.

[0081] It should be noted that the air supplier can provide air with different properties according to actual needs, which is not limited herein. For example, in an embodiment, dry nitrogen can be provided to the inside of the container 13 to protect the precision products in the container 13 from chemical reactions with oxygen and moisture in the air; in another embodiment, pure argon or other inert gas can be provided to the container 13 to simulate the transportation of some products in an oxygen-free environment.

[0082] Further, the heater can increase the temperature of the gas in the container 13 to simulate a high-temperature environment; the cooler can decrease the temperature of the gas in the container 13 to simulate a low-temperature environment, and by flexibly adjusting the heater and the cooler, the temperature of the gas in the container 13 can be controlled, which can effectively simulate the transportation environment of precision products under various temperature conditions. In addition, the humidifier can increase the moisture content in the container 13 to increase the humidity inside, thereby simulating a humid transportation condition. When a dry transportation environment needs to be simulated, the dehumidifier can be used to remove moisture from the gas to reduce the humidity.

[0083] It should be noted that the specific simulation environment in the container 13 can be set according to actual needs by the temperature and humidity environment simulator 3, which is not limited herein. For example, in an embodiment, a high-temperature and high-humidity transportation environment needs to be simulated, which can be simulated by the heater and the humidifier working together; in another embodiment, a low-temperature and dry transportation environment needs to be simulated, which can be simulated by the cooler and the dehumidifier working together.

[0084] The transportation condition simulator provided in the embodiment can greatly simulate various transportation conditions and improve the accuracy of transportation condition simulation by setting the temperature and humidity environment simulator 3.

[0085] The specific implementation principle of the transportation condition simulator provided in the embodiment for simulating the transportation environment is introduced as follows:

[0086] Figure 8 The transport condition simulator shown in an exemplary embodiment of the present application simulates the implementation schematic of the transport environment.

[0087] Referring to Figure 8 The transport condition simulator provided in the present application further comprises a sensor group 200 and a controller 300.

[0088] The controller 300 is configured to control the simulator assembly 100 to simulate any actual transport condition obtained in advance, wherein the actual transport condition is a transport condition described by a combination of mechanical movement, vibration, temperature and humidity.

[0089] The sensor group 200 is arranged inside the container 13 and is configured to measure the simulated transport environment simulated by the simulator assembly 100 in real time and send the simulated transport environment to the controller 300.

[0090] The controller 300 is further configured to adjust the simulator assembly 100 based on the simulated transport environment and the actual transport condition feedback, so that the simulated transport environment matches the actual transport condition, thereby simulating the real transport condition.

[0091] It should be noted that the sensor group 200 at least includes a vibration sensor for testing vibration, a temperature sensor for testing temperature and a humidity sensor for testing humidity.

[0092] Specifically, when the transport environment simulator is used to simulate an actual transport condition, the controller 300 sends a control instruction to the simulator assembly 100 to control the simulator assembly 100 to simulate the actual transport condition.

[0093] It should be noted that the actual transport condition is a transport condition described by a combination of mechanical movement, vibration, temperature and humidity.

[0094] It should be noted that the actual transport condition can be obtained from a wide transport log library, which records a plurality of actual transport conditions, and each transport condition is composed of a set of transport information parameters collected by a set of physical sensors placed on various transport routes around the world.

[0095] It should be noted that, in the simulation of actual transportation conditions, the sensor group 200 and the controller 300 jointly control the simulator assembly 100, and the sensor group 200 measures the simulated transportation environment simulated by the simulator assembly 100 in real time, and feeds back to the controller 300 through the sensor feedback line. Further, the controller 300 can compare the simulated transportation environment with the pre-set actual transportation conditions based on the sensor data, and adjust the simulator assembly 100 through feedback, so that the simulated transportation environment simulated by the simulator assembly 100 is as close as possible to the actual transportation conditions, thereby realizing accurate simulation.

[0096] As can be understood from the foregoing description, the transportation condition simulator can realistically reproduce various environmental conditions and stress conditions of the product in the actual transportation process through the cooperative work of multiple subsystems, and ensure that every detail in the transportation process is reproduced to meet the high-precision transportation environment simulation requirement.

[0097] The transportation condition simulator provided in the embodiment can accurately simulate various complex typical environmental conditions in the transportation process through the combination of the flight environment simulator, the ground environment simulator and the temperature and humidity environment simulator, and can test the stability and tolerance of the product under different transportation modes and extreme environments. In addition, the sensor group can monitor the simulated transportation environment in real time, and the controller can adjust the parameters of the simulator assembly immediately when detecting that the current simulated transportation environment is inconsistent with the actual transportation conditions, so as to ensure that the simulated environment condition simulated by the simulator assembly is as close as possible to the actual situation, thereby ensuring the accuracy of simulation and the reliability of the simulation result. Furthermore, different transportation modes can be simulated through the flexible combination and adjustment of the components in the simulator assembly, and the simulation range is wide. Finally, the actual transportation conditions can be accurately simulated to find problems that may affect the product quality in the transportation process as early as possible, so that the related problems can be rectified to reduce the damage risk in the transportation process and ensure the quality of the final product.

[0098] Optionally, the cavity bottom of the container 13 is provided with a product placing table for placing the product to be tested; wherein the product placing table can be inclined in the length direction and / or the width direction.

[0099] Specifically, the cavity bottom of the container 13 is provided with a product placing table for placing the product to be tested, and in order to simulate the product inclination caused by the bumping in the transportation process, the product placing table can be inclined in the length direction and / or the width direction. In actual implementation, the product placing table can be inclined in the length and width directions through different fixing modes, which are not limited herein.

[0100] For example, Figure 9Fig. 1 shows a partial schematic view of a transport condition simulator according to an example embodiment of the present application. Please refer to Figure 9 In the example shown in Fig. (A) of Figure 9 , the product table can be fixed on the floor of the container 13 by springs; further, in the example shown in Fig. (B) of Figure 9 , the four corners of the product table can be fixed on the floor of the container 13 by four air cylinders respectively, so as to control the tilting of the product table in the length and width directions by the extension and contraction of the air cylinders.

[0101] The transport condition simulator provided by the present embodiment can reproduce the changes of gravity caused by road unevenness or the turning, accelerating and decelerating of the carrier during the transportation, and can more realistically reflect the attitude changes of the product under complex transportation conditions, thereby further improving the accuracy of the simulation.

[0102] Further, corresponding to the aforementioned embodiment of the transport condition simulator, the present application further provides a transport condition simulation method, which will be introduced as follows:

[0103] Figure 10 Fig. 2 shows a flow chart of a transport condition simulation method according to an example embodiment of the present application. Please refer to Figure 10 The transport condition simulation method provided by the present embodiment is applied to the controller 300 in any of the transport condition simulators provided in the first aspect of the present application, and the transport condition simulation method comprises the following steps:

[0104] S1001, for any actual transportation condition acquired in advance, controlling the simulator components in the transport condition simulator to simulate the actual transportation condition; wherein the actual transportation condition is a transportation condition described by a combination of mechanical movement, vibration, temperature and humidity.

[0105] S1002, acquiring the simulated transportation environment simulated by the simulator components in the transport condition simulator, which is measured by the sensor group in real time.

[0106] S1003, based on the simulated transportation environment and the actual transportation condition, adjusting the simulator components to make the simulated transportation environment match the actual transportation condition, so as to make the transport environment simulator simulate a real transportation environment.

[0107] Specifically, the sensor group 200 is installed inside the container 13 to monitor various parameters in the simulated transportation environment in real time, including vibration, temperature, humidity, tilt angle, etc. Further, the sensor converts the acquired data into digital signals and transmits them to the controller 300 for analysis.

[0108] The controller 300 generates a target condition according to the actual transportation condition. The target condition can include a specific vibration mode, a temperature and humidity range, a tilt angle, etc., forming a benchmark model. Further, the controller 300 compares the real-time simulated transportation environment collected by the sensor with the actual transportation condition, and analyzes the difference between the current simulated environment and the target condition. For example, the error or deviation between the two can be calculated to determine whether the simulated environment meets the expectations.

[0109] Further, according to the comparison result between the real-time simulated transportation environment and the target condition, the controller 300 formulates a corresponding adjustment strategy. For example, if the real-time simulated environment fails to meet the target condition, the controller 300 will generate an adjustment instruction to adjust the operation of the simulator assembly 100.

[0110] Further, the controller 300 issues instructions to the simulator assembly 100 (such as the flight environment simulator 1, the ground environment simulator 2, and the temperature and humidity environment simulator 3) through the adjustment signal to adjust it. For example, the operating parameters of the vibration motor can be controlled to increase or decrease the intensity and frequency of the vibration to achieve the desired vibration level. For another example, the temperature and humidity inside the container 13 can be adjusted in real time by the temperature and humidity environment simulator 3 to ensure that it is within the target range. For another example, the tilt angle of the placement table can be adjusted as needed to simulate various postures that may occur during transportation.

[0111] It should be noted that the above process forms a closed-loop feedback system, and the controller 300 continuously monitors the changes in the simulated environment, collects data in real time and compares it with the target condition, to ensure that the simulated environment continuously matches the actual transportation condition. In addition, this process can be iterated multiple times to ensure the accuracy and stability of the simulation.

[0112] The transportation condition simulation method provided by the embodiment can continuously adapt to changes in various transportation environments through the above feedback and adjustment process, so that the simulated transportation condition as closely as possible reflects the actual situation, which can improve the accuracy of the simulation and provide an important basis for subsequent packaging scheme optimization and transportation scheme optimization.

[0113] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
