Description

Technical Field

[0001] This utility model relates to the field of display module production and testing technology, specifically a performance testing device for display module production. Background Technology

[0002] In the assembly of mobile devices, the display screen needs to be assembled with the front shell, resulting in an interference fit. For example, when using conductive foam (conductive cloth, etc.) for grounding, the display screen and conductive foam must be interference-fitted to ensure the grounding effect. When assembling the front-facing camera, a buffer gasket is also needed to hold the screen in place, which can cause structural interference. Therefore, it is necessary to confirm that the screen can withstand the interference force. The current testing method is to place the screen face down and then press it from top to bottom with a pressure plate. After pressing, the pressure head is removed or held, and the screen is flipped over or a person leans down to observe whether there is any display abnormality. This method cannot test the screen's condition when it is subjected to continuous structural interference, resulting in differences in standard judgment.

[0003] The pressure of the pressure plate in the performance testing device is a fixed pressure, which is not easily adjustable to detect the state of the display module under different pressures, thus affecting the accuracy of the performance testing device. Furthermore, the device only performs pressure testing on the display module, making it difficult to simultaneously and accurately measure its dimensions, resulting in a limited range of testing capabilities. Finally, since the display module is typically tested screen-down, it needs to be flipped over for inspection after testing, which is cumbersome and reduces the ease of use of the device. Utility Model Content

[0004] The purpose of this invention is to provide a performance testing device for display module production, in order to solve the problems mentioned in the background art, such as low accuracy, limited testing of display modules, and low convenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a performance testing device for display module production, comprising a support frame, a control keypad mounted on the surface of the support frame, a pressure frame disposed on the inner side of the support frame, the pressure frame slidingly engaging with the support frame via a guide groove on the surface of the support frame, an electric push rod mounted on the surface of the support frame, the input end of the electric push rod being electrically connected to the output end of the control keypad, one end of the electric push rod being fixedly connected to the surface of the pressure frame, a testing platform fixed on the surface of the support frame, the testing platform being located below the pressure frame, a pressure adjusting mechanism disposed inside the pressure frame, the pressure adjusting mechanism including a fixing component and a gravity plate, a precision clamping mechanism disposed on the surface of the testing platform, the precision clamping mechanism including a positioning frame and a precision clamping assembly, and an observation mechanism disposed on the surface of the support frame, the observation mechanism consisting of an observation component and a transparent plate.

[0006] Preferably, a gravity plate is placed inside the pressure frame, and a fixing component is provided between the pressure frame and the gravity plate.

[0007] Preferably, the fixing component consists of a groove, a screw cylinder, and a fixing stud. Grooves are provided on both sides of the surface of the gravity plate, and fixing studs are fixed on both sides inside the pressure frame.

[0008] Preferably, the surface of the fixing stud is threaded with a screw cylinder, the surface of the screw cylinder is in close contact with the surface of the gravity plate, and the diameter of the bottom of the screw cylinder is greater than the width of the groove.

[0009] Preferably, a positioning frame is fixed to the surface of the testing station. The positioning frame has an L-shaped structure, and a precision clamping component is provided on the surface of the positioning frame.

[0010] Preferably, the precision clamping assembly consists of scale lines, clamping strips, sliding grooves, and fastening bolts. Sliding grooves are provided on both sides of the surface of the positioning frame, and two clamping strips are provided on both sides of the surface of the positioning frame. The two clamping strips are perpendicular to each other, and the clamping strips slide in cooperation with the sliding grooves.

[0011] Preferably, the surface of the clamping bar is threaded with a fastening bolt, one end of which passes through the clamping bar and is pressed and fastened to the inner wall of the slide groove. Both sides of the surface of the positioning frame are inlaid with scale lines, which cooperate with the clamping bar.

[0012] Preferably, the transparent plate is embedded inside the testing station, and an observation component is provided below the transparent plate.

[0013] Preferably, the observation component includes an observation mirror, a fixing plate, a magnifying glass, and LED beads. Fixing plates are fixed on both sides at the bottom of the support frame, and the observation mirror is placed between the fixing plates.

[0014] Preferably, LED beads are mounted on the surface of the fixing plate, the input end of the LED beads is electrically connected to the output end of the control key, and a magnifying glass is placed on one side of the fixing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the performance testing device for display module production not only improves the diversity of display module testing, improves the accuracy of the performance testing device, but also improves the convenience of the performance testing device.

[0016] By incorporating a pressure adjustment mechanism, the display module to be tested is flipped and placed inside the positioning frame, ensuring that one corner of the display module is tightly against the angle between it and the positioning frame. Then, the fastening bolts are loosened, and the clamping strip is pushed to slide along the groove, bringing its surface into close contact with the display module surface, thus clamping the display module. Similarly, another clamping strip is placed against the display module. At this point, the scale line values ​​on one side of the clamping strip can be read to accurately display the length and width of the module, allowing for a direct visual inspection of its dimensional compliance. This enables the performance testing device to accurately display the module's dimensions, facilitating dimensional testing of the display module and increasing the versatility of the performance testing device in testing display modules.

[0017] With a precise clamping mechanism, when the pressure of the pressure frame needs to be adjusted, the gravity plate can be placed on one side of the pressure frame, so that the groove fits onto the surface of the fixing stud. Then, the gravity plate is pushed so that it is located inside the pressure frame. Subsequently, the screw cylinder is rotated, and the screw cylinder and the fixing stud are threaded together to make the screw cylinder and the gravity plate fit tightly together, thereby pressing the gravity plate. The weight of the testing table is changed by the number of gravity plates placed, thereby changing the pressure on the display module. This realizes the pressure adjustment function of the performance testing device, which makes it convenient for staff to test the status of the display module when testing different pressures, thereby improving the accuracy of the performance testing device.

[0018] The device is equipped with an observation mechanism. By operating the control panel, the control panel controls the electric push rod, which in turn drives the pressure frame to slide along the support frame, pressing down on the back of the display module. At this time, the observation mirror is placed below the testing table, allowing the front of the display module to be projected onto the surface of the observation mirror through a transparent plate. This allows direct observation of whether there are white spots on the surface of the display module inside the observation mirror, without having to flip the display module over for observation. The LED lights can also be turned on to facilitate observation by the staff. A magnifying glass can be used for more detailed observation, thus enabling the performance testing device to facilitate direct observation of the surface of the display module and improving the convenience of use.

[0025] The present invention provides a performance testing device for display module production, the structure of which is as follows: Figure 1 and Figure 2As shown, the system includes a support frame 1, on the surface of which a control key 104 is mounted. The control key 104 can be of the LA series. A pressure frame 102 is provided on the inner side of the support frame 1. The pressure frame 102 slides against the support frame 1 through a guide groove on the surface of the support frame 1. An electric push rod 101 is mounted on the surface of the support frame 1. The electric push rod 101 can be of the TA series. The input end of the electric push rod 101 is electrically connected to the output end of the control key 104. One end of the electric push rod 101 is fixedly connected to the surface of the pressure frame 102. A detection platform 103 is fixed on the surface of the support frame 1, and the detection platform 103 is located below the pressure frame 102.

[0026] Furthermore, such as Figure 4 As shown, a pressure regulating mechanism 2 is provided inside the pressure frame 102. The pressure regulating mechanism 2 includes a fixing component 201 and a gravity plate 202. The gravity plate 202 is placed inside the pressure frame 102. The fixing component 201 is provided between the pressure frame 102 and the gravity plate 202. The fixing component 201 is composed of a groove 2011, a screw cylinder 2012 and a fixing stud 2013. Grooves 2011 are provided on both sides of the surface of the gravity plate 202. Fixing studs 2013 are fixed on both sides inside the pressure frame 102. The screw cylinder 2012 is threaded onto the surface of the fixing stud 2013. The surface of the screw cylinder 2012 is in close contact with the surface of the gravity plate 202. The diameter of the bottom of the screw cylinder 2012 is greater than the width of the groove 2011.

[0027] When in use, if it is necessary to adjust the pressure of the pressure frame 102, the gravity plate 202 can be placed on one side of the pressure frame 102, so that the groove 2011 fits onto the surface of the fixing stud 2013. Then push the gravity plate 202 so that the gravity plate 202 is located inside the pressure frame 102. Then rotate the screw cylinder 2012. With the threaded engagement between the screw cylinder 2012 and the fixing stud 2013, the screw cylinder 2012 and the gravity plate 202 are pressed tightly together, thereby pressing the gravity plate 202. The gravity of the test stage 103 can be changed according to the number of gravity plates 202 placed, thereby changing the pressure on the display module, so as to realize the pressure adjustment function of the performance testing device and facilitate the display module status when the operator tests different pressures.

[0028] Furthermore, such as Figure 3As shown, the surface of the testing table 103 is provided with a precision clamping mechanism 3. The precision clamping mechanism 3 contains a positioning frame 301 and a precision clamping assembly 302. The positioning frame 301 is fixed to the surface of the testing table 103. The positioning frame 301 has an L-shaped structure. The surface of the positioning frame 301 is provided with a precision clamping assembly 302. The precision clamping assembly 302 is composed of a scale line 3021, a clamping bar 3022, a sliding groove 3023, and a fastening bolt 3024. Both sides of the surface of the positioning frame 301 are open. The positioning frame 301 is provided with a sliding groove 3023. Two clamping strips 3022 are provided on both sides of the surface of the positioning frame 301. The two clamping strips 3022 are perpendicular to each other and slide in the sliding groove 3023. The surface of the clamping strip 3022 is threaded with a fastening bolt 3024. One end of the fastening bolt 3024 passes through the clamping strip 3022 and is pressed and fastened to the inner wall of the sliding groove 3023. Both sides of the surface of the positioning frame 301 are inlaid with scale lines 3021, which cooperate with the clamping strips 3022.

[0029] In use, the display module to be tested is flipped over and placed inside the positioning frame 301, so that one corner of the display module is in close contact with the corner of the positioning frame 301. Then, the fastening bolt 3024 is loosened, and the clamping strip 3022 is pushed to slide along the slide groove 3023, so that the surface of the clamping strip 3022 is in close contact with the surface of the display module, thus clamping the display module. Similarly, the other clamping strip 3022 is pressed tightly against the display module. At this time, the value of the scale line 3021 on one side of the clamping strip 3022 can be read to accurately display the length and width of the module. The size can be visually checked to see if it is qualified, so as to realize the function of the performance testing device to accurately display the module size, and facilitate the performance testing device to perform size testing on the display module.

[0030] Furthermore, such as Figure 2 As shown, the surface of the support frame 1 is provided with an observation mechanism 4, which consists of an observation component 401 and a transparent plate 402. The transparent plate 402 is embedded inside the detection table 103. The observation component 401 is provided below the transparent plate 402. The observation component 401 includes an observation mirror 4011, a fixing plate 4012, a magnifying glass 4013, and an LED bead 4014. Fixing plates 4012 are fixed on both sides at the bottom of the support frame 1. The observation mirror 4011 is placed between the fixing plates 4012. The surface of the fixing plate 4012 is equipped with an LED bead 4014. The input end of the LED bead 4014 is electrically connected to the output end of the control key 104. The magnifying glass 4013 is placed on one side of the fixing plate 4012.

[0031] In use, operate the control key 104 to control the electric push rod 101. Under the action of the electric push rod 101, the pressure frame 102 slides along the support frame 1, pressing down on the back of the display module. At this time, the observation mirror 4011 is placed below the test table 103, and the front state of the display module can be reflected onto the surface of the observation mirror 4011 through the transparent plate 402. It is possible to directly observe whether there are white spots on the surface of the display module inside the observation mirror 4011 without having to flip the display module over to observe it. The LED light beads 4014 can be turned on to facilitate observation by the staff. A magnifying glass 4013 can be used to observe more carefully, so as to realize the function of the performance testing device to facilitate direct observation of the surface of the display module.

[0032] Working principle: In use, first, flip the display module to be tested and place it inside the positioning frame 301, so that one corner of the display module is in close contact with the corner of the positioning frame 301. Then, loosen the fastening bolt 3024 and push the clamping strip 3022 to slide along the slide groove 3023, so that the surface of the clamping strip 3022 is in close contact with the surface of the display module, thus clamping the display module. Similarly, place the other clamping strip 3022 in close contact with the display module. At this time, the value of the scale line 3021 on one side of the clamping strip 3022 can be read to accurately display the length and width of the module. It is possible to intuitively check whether its size is qualified, so as to realize the function of the performance testing device to accurately display the module size, which facilitates the performance testing device to perform size testing on the display module, thereby improving the diversity of the performance testing device when testing the display module.

[0033] Then, operate the control key 104 to control the electric push rod 101. Under the action of the electric push rod 101, the pressure frame 102 slides along the support frame 1, pressing down on the back of the display module. At this time, the observation mirror 4011 is placed below the testing table 103, and the front state of the display module can be reflected onto the surface of the observation mirror 4011 through the transparent plate 402. It is possible to directly observe whether there are white spots on the surface of the display module inside the observation mirror 4011 without having to flip the display module over to observe it. The LED light beads 4014 can be turned on to facilitate observation by the staff. A magnifying glass 4013 can be used to observe more carefully, so as to realize the function of the performance testing device to facilitate direct observation of the surface of the display module, thereby improving the convenience of using the performance testing device.

[0034] When it is necessary to adjust the pressure of the pressure frame 102, the gravity plate 202 can be placed on one side of the pressure frame 102, so that the groove 2011 fits onto the surface of the fixing stud 2013. Then, push the gravity plate 202 so that it is located inside the pressure frame 102. Then rotate the screw cylinder 2012. With the threaded engagement between the screw cylinder 2012 and the fixing stud 2013, the screw cylinder 2012 and the gravity plate 202 are pressed tightly together, thereby pressing the gravity plate 202. The gravity of the test table 103 can be changed according to the number of gravity plates 202 placed, thereby changing the pressure on the display module. This realizes the pressure adjustment function of the performance testing device, which makes it convenient for the staff to test the status of the display module when testing different pressures. This improves the accuracy of the performance testing device and finally completes the use of the performance testing device.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
