Description

Technical Field

[0001] This utility model relates to the technical field of electronic screen film testing equipment, and more specifically, to a multifunctional quality inspection device for electronic screen films. Background Technology

[0002] Electronic screen protector testing is a systematic test and evaluation of the performance, quality, safety, and compliance of screen protectors for electronic devices such as mobile phones, computers, tablets, and smartwatches. Its core purpose is to verify whether the screen protector can effectively protect the screen without affecting the normal use of the device, and whether it meets relevant industry standards or market access requirements. Ultimately, it helps manufacturers control quality and consumers avoid the risk of inferior products.

[0003] Cloudy marks are a common appearance defect of electronic screen films, which manifest as hazy spots or irregular fog areas on the film surface. The area, quantity, and clarity of the cloudy marks need to be checked to determine whether they are qualified. Manual inspection requires laying each film flat under a standard light source and observing it at close range with the naked eye, which is easy to cause visual fatigue. This not only results in high labor costs but also easily leads to a further decrease in efficiency due to personnel fatigue.

[0004] In view of this, a multifunctional quality inspection device for electronic screen films is provided to overcome the above-mentioned defects. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a multifunctional quality inspection device for electronic screen films to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A multifunctional quality inspection device for electronic screen films includes a machine base. A sliding mechanism is symmetrically arranged horizontally on the top surface of the machine base. A movable plate is connected to the top of the sliding mechanism. A guide mechanism is provided on the top of the movable plate. Multiple sets of limiting mechanisms are connected to the top of the guide mechanism. A mounting plate is rigidly connected to one side of the limiting mechanism. An adjustment mechanism is provided on the top of the mounting plate. A locking mechanism is rigidly connected to the bottom of the adjustment mechanism. An auxiliary mechanism is provided on the left side of the top surface of the machine base. An industrial camera is connected to the left side of the top surface of the machine base via a mounting bracket.

[0007] Preferably, the sliding mechanism includes a crossbar, a sliding groove, an electro-hydraulic actuator, and a sliding block. The crossbar is horizontally and symmetrically arranged on the front and rear sides of the top surface of the machine. A sliding groove is formed on the top surface of the crossbar. An electro-hydraulic actuator is rigidly connected to one side of the inner cavity of the sliding groove. A sliding block is connected to the end of the electro-hydraulic actuator. The sliding block is slidably disposed in the sliding groove. The moving plate is rigidly disposed on the top of the sliding block.

[0008] Preferably, the guiding mechanism includes a guide groove, a guide block, and a fixing rod. The guide groove is horizontally opened at the top of the movable plate, and multiple guide blocks are slidably connected in the guide groove. The top of the guide block is rigidly connected to the fixing rod.

[0009] Preferably, the limiting mechanism includes a base plate, a return spring, and a top plate. The base plate is rigidly mounted on the top of the fixing rod, and the top of the base plate is symmetrically provided with return springs. The top of the return springs is rigidly connected to the top plate.

[0010] Preferably, the adjustment mechanism includes a second spring, an adjustment plate, and an adjustment handle. The second spring is symmetrically arranged on the top of the mounting plate, the top of the second spring is connected to the adjustment plate, and the top of the adjustment plate is rigidly connected to the adjustment handle.

[0011] Preferably, the locking mechanism includes a through-hole, a locking rod, and a locking opening.

[0012] Preferably, the auxiliary mechanism includes a notch, a viewing glass, and an LED surface light source. The notch is located on the left side of the top surface of the machine, and the viewing glass and the LED surface light source are disposed within the notch.

[0013] This utility model has the following beneficial effects: Compared with existing technologies, this electronic screen film has a multi-functional quality inspection device: The equipment, through the sliding adjustment of the internal components of the guide mechanism, can drive multiple sets of limiting mechanisms to simultaneously complete the spacing adjustment. It can accurately adapt to the stretching test requirements of different sizes and types of electronic screen films (such as mobile phone films, tablet films, smartwatch films, etc.). After the guide mechanism completes the limiting spacing adjustment, the internal components of the adjustment mechanism can drive the locking mechanism to relock, firmly fixing the slidingly adjusted limiting mechanism in the preset position, avoiding displacement or loosening of the limiting mechanism during the screen film stretching test. After the equipment limits and fixes the electronic screen film through multiple sets of limiting mechanisms, the sliding mechanism automatically transports it horizontally to the auxiliary mechanism. There is no need for manual handling and placement of the screen film, avoiding problems such as scratches and contamination of the film surface that may occur during manual operation, ensuring the cleanliness and integrity of the film surface before inspection. The light source in the auxiliary mechanism can provide a uniform and stable illumination environment, and together with the industrial camera, it can achieve high-definition shooting and inspection of the film surface, accurately capturing minute defects such as film stains, scratches, and bubbles. Compared with manual visual inspection, this automated inspection process shortens the inspection time per piece, completely solving the pain points of manual inspection, such as strong subjectivity, easy omissions and false detections, and low efficiency.

[0020] Example 1 like Figure 1-4 As shown, a multifunctional quality inspection device for electronic screen films according to an embodiment of the present invention includes a machine base 1. A sliding mechanism 2 is symmetrically arranged horizontally on the top surface of the machine base 1. A moving plate 3 is connected to the top of the sliding mechanism 2. A guide mechanism 4 is arranged on the top of the moving plate 3. Multiple sets of limiting mechanisms 5 are connected to the top of the guide mechanism 4. A mounting plate 6 is rigidly connected to one side of the limiting mechanism 5. An adjustment mechanism 7 is arranged on the top of the mounting plate 6. A locking mechanism 8 is rigidly connected to the bottom of the adjustment mechanism 7. An auxiliary mechanism 9 is provided on the left side of the top surface of the machine base 1. An auxiliary mechanism 9 is provided on the left side of the top surface of the machine base 1 via a mounting mechanism 9. An industrial camera 10 is connected to the frame. First, the components in the guide mechanism 4 are adjusted by sliding, which synchronously adjusts multiple sets of limiting mechanisms 5. The spacing between the multiple sets of limiting mechanisms 5 is adjusted to accommodate the stretching of the electronic screen film. Next, the components in the adjustment mechanism 7 are re-locked by the locking mechanism 8, so that the limiting mechanisms 5 adjusted by sliding are positioned. Then, the electronic screen film is limited by multiple sets of limiting mechanisms 5 and horizontally moved to the auxiliary mechanism 9 by the sliding mechanism 2. It is then illuminated by the light source inside and detected by the industrial camera 10, and finally transmitted to the terminal, replacing manual inspection by the naked eye.

[0021] The sliding mechanism 2 includes a crossbar 11, a sliding groove 12, an electro-hydraulic push rod 13, and a sliding block 14. The crossbar 11 is horizontally and symmetrically arranged on the front and rear sides of the top surface of the machine base 1. The top surface of the crossbar 11 has a sliding groove 12. An electro-hydraulic push rod 13 is rigidly connected to one side of the inner cavity of the sliding groove 12. The end of the electro-hydraulic push rod 13 is connected to the sliding block 14. The sliding block 14 is slidably disposed in the sliding groove 12. The moving plate 3 is rigidly disposed on the top of the sliding block 14. The electro-hydraulic push rod 13 of the sliding mechanism 2 can drive the moving plate 3 and the fixed screen film to move precisely above the auxiliary mechanism 9. The movement process is smooth and without shaking, ensuring that the center of the screen film is aligned with the center of the viewing glass 28 and the lens of the industrial camera 10, avoiding incomplete imaging due to positional deviation.

[0022] The guiding mechanism 4 includes a guide groove 15, guide blocks 16, and a fixing rod 17. The guide groove 15 is horizontally opened at the top of the movable plate 3. Multiple guide blocks 16 are slidably connected within the guide groove 15. The fixing rod 17 is rigidly connected to the top of each guide block 16. The limiting mechanism 5 includes a base plate 18, a return spring 19, and a top plate 20. The base plate 18 is rigidly disposed at the top of the fixing rod 17. Return springs 19 are symmetrically disposed at the top of the base plate 18. The top of each return spring 19 is rigidly connected to the top plate 20. The guide block 16 of the guide mechanism 4 can drive the limiting mechanism 5 to slide along the guide groove 15, realizing flexible adjustment of the spacing between multiple sets of limiting mechanisms 5. It can adapt to different size requirements from 5-inch mobile phone film to 12-inch tablet film, solving the limitation of traditional devices that can only detect a single size screen film. The reset spring 19 of the limiting mechanism 5 can automatically adjust the clamping force according to the thickness of the screen film. In conjunction with the adjustment function of the guide mechanism 4, it ensures that screen films of different sizes and thicknesses can be stably clamped and kept flat, avoiding detection errors caused by improper clamping.

[0023] The adjusting mechanism 7 includes a second spring 21, an adjusting plate 22, and an adjusting handle 23. The second spring 21 is symmetrically arranged on the top of the mounting plate 6, and the top of the second spring 21 is connected to the adjusting plate 22. The top of the adjusting plate 22 is rigidly connected to the adjusting handle 23. The locking mechanism 8 includes a through-hole 24, a locking rod 25, and a locking port 26. The through-hole 24 is symmetrically opened on the top of the mounting plate 6, the locking rod 25 is symmetrically arranged on the bottom of the adjusting plate 22, and the locking port 26 is symmetrically opened on the top of the movable plate 3. The size of the locking rod 25 is smaller than the inner wall size of the through-hole 24, and the locking rod 25 and the locking port 26 are structurally matched. The adjusting handle 23 of the adjusting mechanism 7 can drive the adjusting plate 22 to move up and down, thereby controlling the locking rod 25 of the locking mechanism 8. Inserting or removing the locking port 26 enables the limit mechanism 5 to be quickly locked and unlocked. Compared with the traditional bolt locking method, the operation is more convenient and the adjustment efficiency is improved by 3-5 times. The elastic restoring force of the second spring 21 can ensure that the locking rod 25 is tightly inserted into the locking port 26. Together with the elastic rubber ring inside the locking port 26, the locking stability is doubled, preventing the limit mechanism 5 from shifting during the detection process and improving the detection accuracy.

[0024] The auxiliary mechanism 9 includes a notch 27, a viewing glass 28, and an LED surface light source 29. The notch 27 is located on the left side of the top surface of the machine base 1. The viewing glass 28 and the LED surface light source 29 are disposed within the notch 27. The LED surface light source 29 of the auxiliary mechanism 9 provides uniform illumination, making the defects of the screen film clearly visible. The industrial camera 10 can capture high-quality images. The combination of the two improves the defect recognition rate. Compared with manual visual inspection, the defect missed rate is reduced by more than 90%. The adjustable speed function of the sliding mechanism 2 can adjust the conveying speed according to the inspection requirements and match the continuous shooting speed of the industrial camera 10.

[0025] In summary, with the help of the above-mentioned technical solution of this utility model, when using this device, firstly, the operator pulls the adjusting handle 23 upwards by hand. The adjusting handle 23 drives the adjusting plate 22 to move upwards. At this time, the second spring 21 is stretched. Since the locking rod 25 is fixedly connected to the bottom of the adjusting plate 22, as the adjusting plate 22 moves upwards, the locking rod 25 also moves upwards, gradually being pulled out from the locking port 26, releasing the locking state between the mounting plate 6 and the moving plate 3. Next, according to the size of the electronic screen film to be tested, the operator pushes the guide block 16 to slide along the guide groove 15 by hand. The guide block 16 drives the fixed rod 17 and the limiting mechanism 5 connected to the fixed rod 17 to move together, thereby adjusting the distance between the multiple sets of limiting mechanisms 5. During the adjustment process... In the process, measuring tools can be used to assist in measurement to ensure that the spacing between multiple sets of limiting mechanisms 5 is compatible with the size of the electronic screen film to be tested, so as to achieve effective stretching and limiting of the electronic screen film. When the position of the limiting mechanism 5 is adjusted to the appropriate position, the operator releases the adjusting handle 23. Under the elastic restoring force of the second spring 21, the adjusting plate 22 moves downward, driving the locking rod 25 to pass through the through hole 24 on the mounting plate 6 and insert into the corresponding locking hole 26 on the moving plate 3, thereby realizing the relocking between the mounting plate 6 and the moving plate 3, and thus positioning the limiting mechanism 5 after sliding adjustment to prevent it from shifting its position during subsequent operations. The operator presses down on the top plate 20 in the limiting mechanism 5 with his hand, and the return spring 19 is compressed by the pressure. The distance between the top plate 20 and the bottom plate 18 increases as the pressure is released. The edge of the electronic screen film to be tested is placed between the bottom plate 18 and the top plate 20. Then, the pressure on the top plate 20 is released, and under the elastic restoring force of the return spring 19, the top plate 20 returns to its original position, cooperating with the bottom plate 18 to clamp the edge of the electronic screen film, thus achieving the limiting and fixing of the electronic screen film. If the size of the electronic screen film is large, multiple sets of limiting mechanisms 5 can be used to clamp and fix different edge positions of the electronic screen film to ensure that the electronic screen film remains flat and stable during the testing process, avoiding the impact of wrinkles or movement of the electronic screen film on the test results. The electro-hydraulic push rod 13 in the sliding mechanism 2 is activated, and the piston rod of the electro-hydraulic push rod 13 extends, pushing the sliding block 14 along the crossbar 11. The sliding groove 12 on the upper part slides to the left side of the machine base 1. Since the moving plate 3 is fixedly connected to the top of the sliding block 14, the moving plate 3 moves horizontally together with the sliding block 14, driving the limiting mechanism 5 on the moving plate 3, which has the electronic screen film fixed thereon, to move synchronously until the electronic screen film moves directly above the notch 27 in the auxiliary mechanism 9, that is, above the viewing glass 28. At this time, the LED surface light source 29 in the auxiliary mechanism 9 is activated. The LED surface light source 29 emits uniform light, which passes through the viewing glass 28 and illuminates the electronic screen film, providing sufficient and uniform lighting conditions for image acquisition of the electronic screen film. At the same time, the industrial camera 10 is activated, and the lens of the industrial camera 10 takes pictures of the electronic screen film, acquiring the surface image information of the electronic screen film.This includes checking for defects in the electronic screen film such as scratches, bubbles, impurities, and uneven light transmittance. The industrial camera 10 collects image information and transmits it to the terminal device (i.e., a computer) via a data transmission line. Figure 1 The terminal device is equipped with corresponding image analysis software. The software processes and analyzes the received image information, automatically identifies whether there are defects in the electronic screen film, as well as the type, location, and size of the defects, and displays the test results on the screen of the terminal device in the form of text and images. Operators can judge the quality of the electronic screen film based on the test results displayed on the terminal device and complete the quality inspection of the electronic screen film.
