Description

Technical Field

[0001] The invention relates to the technical field of flexible electronics, and in particular to a flexible electronic product testing device. Background Art

[0002] As a new cross-disciplinary science and technology, the flexible electronic devices or systems derived from flexible electronic technology have the characteristics of being light, thin, soft and small. Combined with functional design, they can realize functions such as parameter sensing, data acquisition and transmission, and are widely used in medical health, new display technology, intelligent equipment and other fields. During service, such flexible electronic devices and systems are usually conformally attached to irregular curved surfaces and need to withstand the coupling of bending stress and complex environment and load, which makes them very prone to reliability problems. Therefore, reliability testing of flexible electronic products is very critical to ensure their basic quality and service effect. Impact resistance test and temperature test are important test items for reliability testing of electrical and electronic products. Among them, the impact resistance test can use a vertical impact test bench to achieve the corresponding load application, and the temperature test can complete the environmental application through a temperature chamber. However, they are currently carried out independently of each other, and there is a lack of bending stress application module, which makes it impossible to achieve comprehensive testing of bending stress in the service scenario of flexible electronic products. In addition, in terms of the design of a separate impact resistance test scheme, existing methods include vertical drop hammer impact method and air cannon accelerated impact method. In order to achieve a high G value effect, the test equipment is relatively large in scale, which places high demands on the load-bearing and vibration isolation of the site, and there are problems such as secondary impact. Compared with small flexible electronic devices and system samples, there is also volume redundancy. In addition to the application of test loads, performance monitoring of test samples is also important for reliability analysis, and general equipment does not have relevant configurations.

[0003] Impact test and temperature test are important test items for reliability testing of electrical and electronic products. In the current reliability test technology, the impact test can use a vertical impact test bench to achieve the corresponding load application, and the temperature test can use a temperature chamber to complete the environmental application, but they are mainly carried out independently of each other. In the design of a separate impact resistance test scheme, in order to achieve a high G value effect, the existing methods include the vertical drop hammer impact method and the air cannon accelerated impact method. The test equipment formed is generally large in scale, which places high requirements on the site's load-bearing and vibration isolation, and some have problems such as secondary impact.

[0004] In terms of environmental comprehensive reliability testing systems, there are currently similar temperature, humidity and vibration three-in-one testing systems, but they lack the synchronous loading of bending stress. In addition, this type of temperature, humidity and vibration three-in-one testing system can only achieve simulated loading of small-scale typical impacts, which is not suitable for the high-G value testing requirements of flexible electronic devices or systems, and the overall specifications of the comprehensive testing system are usually large. Summary of the invention

[0005] The present invention aims at at least one shortcoming in the prior art, including the coupled loading problem of bending stress and impact and temperature environment of flexible electronic products, and provides a flexible electronic product testing device.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0033] Figure 2 is a schematic diagram of the flexible electronic product testing device without the temperature chamber;

[0034] Figure 3 It is a schematic diagram of the temperature box. DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] The “top” and “bottom”, “front” and “back”, “lateral” and “longitudinal”, “below” and “above” mentioned in this article are relative position descriptions, not absolute position descriptions.

[0037] A flexible electronic product testing device, overall reference Figures 1 to 3 ,include:

[0038] The vertical impact module comprises a base 10, a felt seat 20 on the base 10, an impactor 30, a transmission mechanism and a driving mechanism connected to the transmission mechanism; wherein the base 10 and the felt seat 20 are an integrated structure; preferably, an integrated convex structure, such as Figure 2 Displayed in.

[0039] The impactor 30 realizes displacement away from the felt seat and acceleration displacement toward the felt seat through a transmission mechanism and a driving mechanism; the felt seat 20 has a hollow area 21 inside, and a columnar impact contact area 22 is provided on the top of the felt seat. The impact contact area 22 protrudes from the top of the felt seat, and the impact contact area 22 is located at the end position of the displacement path of the impactor 30;

[0040] The temperature and bending loading module is located below the impactor 30, and includes a temperature box 40 and a curved surface structure 50. The temperature box 40 wraps the hollow area 21 of the felt seat 20; wherein the curved surface portion of the curved surface structure 50 is used to load the sample; the curved surface structure 70 is detachably fixed to the hollow area 21 of the felt seat 20 near the impact contact area 22 and covers the impact contact area 22.

[0041] The automatic control and monitoring module comprises an input end and an output end respectively. The input end and the output end are respectively connected to the vertical impact module and the temperature and bending loading module for obtaining monitoring signals and outputting control signals.

[0042] Among the three modules mentioned above, the vertical impact module is used to generate shock waves with a certain pulse width and acceleration peak value; the temperature and bending loading module is used to load the sample with temperature environment and bending stress; the automatic control and monitoring module is used for the start and stop control, parameter setting, and data monitoring and display of the test device.

[0043] Preferably, in this embodiment, the impact contact area is a cylindrical impact contact area.

[0044] The transmission mechanism includes a guide arm 60. Vertical through holes are respectively provided at both lateral ends of the impactor. The guide arm 60 is installed through the vertical through holes so that the impactor moves along the guide arm; the guide arm can ensure the verticality of the impactor when it falls.

[0045] The transmission mechanism also includes a connecting rod 61, a pulley 62, a rope 63, and a lifting block 64. The connection relationship between the transmission mechanism and the driving mechanism is as follows:

[0046] A set of driving mechanisms are respectively provided at the two lateral ends of the base, and the driving mechanisms include a telescopic hydraulic cylinder 70, the bottom of which is fixed to the base 10, and the top of the telescopic rod of the telescopic hydraulic cylinder 70 is installed with a pulley 62 through a connecting rod 61, and the pulley 62 has a degree of rotational freedom. A rope 63 is provided with one end fixed to the base 10, and the other end is bent around the pulley 62 and passes through the mounting hole on the impactor 30, and the other end is fixed to the lifting block 64. Generally speaking, the impactor is provided with side ears on both sides, and the side ears are provided with vertical through holes and rope mounting holes.

[0047] The rope 63 can shuttle up and down in the mounting hole of the side ear of the impactor, and the volume of the pulling block 64 needs to be larger than the mounting hole size of the side ear so that it cannot pass through the side ear.

[0048] According to the above structure, the following operations can be achieved:

[0049] The telescopic rod of the telescopic hydraulic cylinder extends, and the rope drives the pulley to rotate to realize the upward movement of the lifting block, which then contacts the side ear and drives the impactor to move upward, causing the impactor to move away from the felt seat;

[0050] The telescopic rod of the telescopic hydraulic cylinder retracts, causing the impactor to move toward the felt seat.

[0051] Specifically, when the telescopic rod of the telescopic hydraulic cylinder retracts and the impactor moves toward the felt seat, it is a gravity descent process; the rope is implemented as a high-strength rope, which can support repeated lifting and pulling operations on the impactor.

[0052] The two telescopic hydraulic cylinders are connected to the oil pump through pipelines to achieve telescopic control.

[0053] Exemplarily, in this embodiment, a group of telescopic hydraulic cylinders of the same model and specification are respectively arranged at the two lateral ends of the base.

[0054] As a preferred solution, an oil brake mechanism is provided at the connection portion between the impactor and the guide arm. The oil brake mechanism is connected to an oil pump and can achieve locking between the impactor and the guide arm.

[0055] As a preferred solution, in order to achieve high G-value impact, the vertical impact module further includes an elastic acceleration device 80 and a top support structure 81.

[0056] The top of the guide arm 60 is connected to the top support structure 81, and an elastic acceleration device 80 is arranged between the top support structure 81 and the impactor 30;

[0057] The elastic acceleration device includes a spring assembly 82 , one end of which is mounted on the top support structure 81 , and the other end of which is mounted with a thrust plate 83 , wherein the lower surface of the thrust plate 83 is opposite to the upper surface of the impactor 30 .

[0058] Through the above structural design, a high-strength top support structure is arranged on the top of the guide arm and is rigidly connected to the guide arm. An elastic accelerator is installed on the lower surface of the top support structure. The basic principle of the elastic acceleration device is to store energy through spring compression and release energy by rebounding instantly at the beginning of the impact test. The spring assembly can be realized by a similar principle of gas compression and release. The bottom of the elastic acceleration device is a thrust plate, and the bottom surface of the thrust plate is arranged to be a material layer with a certain toughness to avoid completely rigid contact with the top of the impactor.

[0059] The operation process is: during the preparation of the impact test, the lifting block is linked by the hydraulic cylinder to drive the impactor to gradually move upward and contact the lower surface of the elastic acceleration device, and continue to drive the elastic acceleration device to complete compression energy storage. After the impactor reaches the specified height, the oil brake device is used to lock it with the guide arm.

[0060] Then the lifting block is driven downward by the retraction of the hydraulic cylinder, and the free release of the impactor is achieved by turning off the locking function of the impactor. Combined with the elastic acceleration device, it rebounds synchronously at the moment of release and pushes the impactor to accelerate down until it collides with the impact contact area of ​​the felt seat. A specified impact waveform will be generated at the moment of collision. The elastic acceleration device can effectively increase the acceleration of the impactor, thereby achieving high G-value impact under small stroke and reducing the requirements for the height of the impact module.

[0061] Near the impact contact area on the top of the felt seat, an acceleration sensor 23 is provided to measure the acceleration history curve of the impact process. Specifically, it is a mechanical acceleration sensor.

[0062] As a preferred solution, multiple foot supports 11 with impact buffering effect are arranged around and in the middle area of ​​the base, and are connected to the ground connecting plate to achieve the alleviation of shock waves to reduce the bearing and vibration isolation requirements on the ground; bolt fastening holes are arranged around the ground connecting plate for a firm connection with the ground during installation to ensure the safety of the test.

[0063] like Figure 2 As shown in the figure, the felt seat 20 and the base 10 are connected to form an integrated convex body structure, the upper layer of which is a hollow area 21. The preferred felt seat is a front and rear through-structure, and the bottom of the felt seat is a solid structure. Specifically, the bottom and the upper surface of the base share a surface, and the whole is made of high-strength metal material to bear the impact load when the impactor falls. The center of the top is a cylindrical impact contact area, and the upper surface of the impact contact area is used to place a felt pad layer. The coordinated adjustment of the impact waveform and pulse width can be achieved by placing felt pad layers of different thicknesses and different materials.

[0064] Preferably, a hollow outer frame cover is arranged on the upper surface of the impact contact area to fix the felt layer. When adjusting the felt pad layer, it is necessary to first pick up the hollow outer frame cover of the contact area, and after the felt pad layer is placed, the edge of the felt layer is fixed by closing the outer frame cover to ensure stability during the impact contact process.

[0065] Preferably, if the side of the curved surface structure close to the impact contact area is arranged to be close to the lower surface of the top of the felt seat, the impact force can be better transmitted to the curved surface structure, which is more beneficial to the accuracy of the test data.

[0066] Among them, the curved surface part is set away from the felt seat, the curvature radius of the curved surface part of the curved surface structure is consistent, and the curved surface structure as a whole is fastened to the hollow area of ​​the felt seat through threaded holes on both sides. The threaded hole installation can be conveniently replaced to achieve adjustment of different bending radii. The sample is conformally attached to the curved surface of the bending device during the test.

[0067] The main function of the temperature box is to apply high and low temperature environments; in one embodiment, the bottom of the temperature box is connected to the base as a whole, and the top of the temperature box covers the top of the felt seat, which can also be understood as the temperature box wrapped around the outside of the felt seat. At the same time, the top of the temperature box is provided with holes that match the impact contact area on the surface of the felt seat, so that the impact contact area just protrudes from the outside.

[0068] If the impact contact area is a cylindrical impact contact area, the corresponding hole on the top of the temperature box is a circular hole.

[0069] Preferably, the edge of the hole at the top of the temperature box 40 is connected to the boundary of the impact contact zone through soft insulation materials such as insulation cotton or insulation rubber to prevent the impact load borne by the felt seat from having a significant impact on the temperature box structure.

[0070] In addition, the temperature box 40 is also provided with matching holes at the corresponding positions of the acceleration sensor 23 on the top of the felt seat, so that the acceleration sensor 23 is rigidly fixed to the felt seat and exposed to the outside of the temperature box 40, thereby preventing temperature changes from affecting the performance of the acceleration sensor.

[0071] In another embodiment, the bottom of the temperature box is connected to the base as a whole, and the top of the temperature box is flush with the side of the top of the felt seat. It can also be understood that the top of the temperature box does not cover the top of the felt seat. In this structure, there is no need to open a hole for the impact contact area to be exposed, and there is no need to set a hole for the temperature sensor to be exposed.

[0072] The front side of the temperature box 40 is provided with a door structure 41 of the box body, which can be opened and closed by a hinge. Preferably, the temperature and bending loading module also includes a transparent window, specifically a double-layer heat-insulated transparent window provided in the middle of the door structure, which can be used to observe the internal sample state in real time.

[0073] The rear side of the temperature box 40 is a temperature generating device 43 such as a compressor; a plurality of metal conductive columns 42 or integrated electrical connectors are installed on the side of the temperature box, and the conductive columns 42 connect the inside and outside of the box to realize the power supply connection of the external power supply to the inside, as well as the wired connection of the internal and external signals, which is particularly suitable for the real-time measurement of electrical signals during the test process.

[0074] The automation control and monitoring module includes an oil pump 71, a host 72, a data display interface, an industrial control cabinet, etc., and each component is placed in a layered fixed manner in the industrial control cabinet. The oil pump 71 is placed at the bottom, one end of which is connected to the oil brake device of the vertical impactor and two telescopic hydraulic cylinders, and the other end is connected to the oil source.

[0075] The control of the entire test device is completed by the host 72. On the one hand, it is connected to the temperature generating device, oil pump, etc. to control various test parameters such as impact and temperature. On the other hand, it is connected to the conductive column, acceleration sensor, etc. to monitor the output electrical signal of the sample.

[0076] In terms of secondary impact control, by setting the locking time after the peak acceleration of the oil brake device, the locking of the impactor after rebound is achieved, thereby avoiding secondary impact on the sample.

[0077] The data display interface has basic functions such as display analog and digital settings, data monitoring, and data storage. In addition, it can further integrate advanced data processing algorithms to realize test data presentation. It can timely display the test parameter setting level and the actual monitoring level, and can be connected to the host for common use to achieve effective analysis of test parameters.

[0078] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different. Any equivalent or simple changes made based on the structure, features and principles described in the patent concept of the present invention are included in the protection scope of the patent of the present invention. The technicians in the technical field of the present invention can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the present invention or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
