Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of product detection, and in particular to a multi-form folding detection device with environmental change function. BACKGROUND

[0002] With the rapid development of intelligent electronic product technology, consumers' requirements for the performance and quality of electronic products are increasing. As an important interface for users to interact with electronic products, electronic products not only need to have display performance such as high resolution and high color saturation, but also need to have good flexibility and durability to adapt to various use scenarios and operation modes, among which folding operation is one of the common use behaviors.

[0003] At present, the existing electronic product folding detection devices on the market can only perform folding tests on products in normal temperature and humidity environments, and cannot simulate various complex environmental conditions that may be encountered in actual use. However, electronic products will face various extreme environments in actual use, such as high-temperature and humid summer outdoor environments, low-temperature and dry winter indoor environments, etc. These environmental factors will have a significant impact on the physical and chemical properties of electronic products, and thus affect the performance and life of the products during folding.

[0004] Folding tests in normal temperature and humidity environments can detect the flexibility and fatigue resistance of products under ideal conditions, but cannot accurately evaluate the performance changes and potential problems of products under extreme environments. For example, in a high-temperature and humid environment, the product material may soften and swell, causing the product to be more prone to indentation, deformation, and other problems during folding; while in a low-temperature and dry environment, the product material may become brittle and hard, with reduced impact resistance, and is prone to cracking or even breaking during folding. Therefore, the existing folding detection devices cannot meet the demand for performance evaluation of electronic products under complex environmental conditions.

[0005] When folding tests are performed on electronic products in a high-temperature and humid environment, the products will exhibit a series of performance changes different from those in a normal temperature and humidity environment. During multiple folding processes, the products are prone to indentation detection problems. This is because in a high-temperature and humid environment, the flexibility of the product material increases, but the resistance to deformation decreases. When the product is subjected to folding force, the material is prone to local plastic deformation, forming indentations. These indentations not only affect the appearance quality of the product, but also may affect the touch performance and display effect of the product. For example, indentations may cause abnormal touch signals, resulting in touch insensitivity or false touch; at the same time, indentations may also cause changes in the internal optical structure of the product, leading to color difference, uneven brightness, and other phenomena in the display image, so indentation quality inspection of products in a high-temperature and humid environment is very important for performance inspection.

At this time, the probe 59 contacts the product after it has been folded in the high temperature environment and performs smoothness detection. When the pressure on the probe 59 changes in stages, it is determined that the product has dents under the high temperature state. The number of times the product is folded at this time is recorded and evaluated. After the test is completed, the spring telescopic air box 57 will draw gas back into the spring telescopic air box 57 from the one-way air valve for the next test.

[0043] like Figure 9 As shown, there are multiple conductive blocks 46, and the current flowing through the multiple conductive blocks 46 gradually decreases, with the conductive block 46 closest to the fixed end of the third electric telescopic rod 48 having the largest current.

[0044] To facilitate the staff to change the mass of the counterweight 42, thereby changing the size of the rectangular through hole of the baffle plate 49 blocking the fixing box 410, thus creating environments with different temperatures and humidity levels, the product can quickly complete the folding performance evaluation under different environments.

[0045] like Figure 9 As shown, the folding plate 513 is composed of two straight plates spliced ​​together, with the angle between the two straight plates being 30°-120°.

[0046] At different angles, the folding plate 513 can cause the counterweight 42 to drive the second connecting rod 45 to push and squeeze the folding plate 513 to move different distances during the clockwise rotation of the clamping plate 34, thereby resulting in different amounts of water sprayed out and creating different degrees of humid environment for testing purposes.

[0047] like Figure 1 As shown, a controller is installed inside the installation box 1.

[0048] To facilitate the start-up and shutdown of each unit, and to enable a rapid response in case of emergencies.

[0049] Working principle of the invention: After the product to be tested is transported to the pull plate 23, the controller controls the first electric telescopic rod 22 to start, pulling the pull plate 23 to move backward along the long plate 24. After completion, the controller controls the first electric push plate 25 to start, driving the long plate 24, the pull plate 23 and the fixed plate 21 to move upward, lifting the product to the designated height and completing the transportation of the product.

[0050] At this time, the controller controls the robot arm 32 to rotate to the designated position, and then controls the second electric telescopic rod 35 to retract, thereby driving the clamping plates 34 to move closer together to clamp the product. At this time, the controller controls the rotary motor 33 to drive the clamping plates 34 to rotate. During this period, the robot arm drives the product to move closer to the light source plate 37 and maintains the current state to perform ambient light calibration and testing. At the same time, after the product rotation is completed, the controller controls the second electric push plate 38 to push the support frame 39 and the roller 310 to move upward multiple times, and fold the product 90° for testing.

[0051] In the process of rotating the clamping plate 34 counterclockwise, the counterweight 42 drives the second connecting rod 45 to move left, and the second connecting rod 45 drives the push rod 51 to push the rotating plate 53 to rotate to the horizontal state. On the one hand, the push rod 51 drives the first conductive plate 54 to press the buffer spring 512 and contact the second conductive plate 55. At this time, the current of the first conductive plate 54 is transmitted to the extension end of the spring extension air tank 57 through the second conductive plate 55. Under the action of the same polarity repulsion, the rotating plate 53 drives the extension end of the spring extension air tank 57 to move backward, thereby driving the gas inside the air tank to push the screw rod 58 to rotate and move upward at the same time. At this time, the probe 59 contacts the product after folding in the high temperature environment and detects the smoothness. When the pressure on the probe 59 changes periodically, it is determined that the product has a dent in the high temperature state. The folding number of the product at this time is recorded for evaluation. After the test is completed, the spring extension air tank 57 will reabsorb the gas from the one-way air valve into the spring extension air tank 57 for next test.

[0052] In the process of rotating the clamping plate 34 counterclockwise, the counterweight 42 drives the second connecting rod 45 to move left, and the second connecting rod 45 drives the push rod 51 to push the rotating plate 53 to rotate to the horizontal state. On the one hand, the push rod 51 drives the first conductive plate 54 to press the buffer spring 512 and contact the second conductive plate 55. At this time, the current of the first conductive plate 54 is transmitted to the extension end of the spring extension air tank 57 through the second conductive plate 55.
