Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, and in particular to a conductive thin film testing tooling. Background Technology

[0002] Visual inspection fixtures for conductive films are specialized equipment used in the production and processing of conductive films to detect surface and performance defects. These fixtures are crucial for quality control and improving production efficiency. Firstly, their core purpose is to achieve accurate defect detection: During the coating, drying, and winding processes, conductive films are prone to defects such as pinholes, scratches, uneven coating, and abnormal conductivity. These defects directly affect the performance of the film in electronic devices (such as touchscreens and flexible circuit boards). Visual inspection fixtures capture details of the film surface using high-definition cameras, and combined with image algorithms, can quickly identify these minute defects. They can even detect micron-level pinholes or localized coating thickness deviations that are difficult to distinguish with the naked eye. Compared to manual inspection, this significantly improves the defect recognition rate and detection efficiency, preventing unqualified products from entering downstream processes.

[0003] Current visual inspection fixtures for conductive films on the market generally suffer from a significant drawback: inconvenient adjustment of high-definition cameras. This severely impacts the applicability and efficiency of inspection when dealing with the inspection needs of conductive films of varying widths. Most existing fixtures use a fixed-mount design for their high-definition cameras, which are directly bolted to the fixture's beam or bracket. However, in actual production, the width of the conductive film needs to be adjusted according to downstream customer requirements. When inspecting films of different widths, fixed-mount cameras cannot flexibly adjust their spacing; for narrower films, the shooting range of some cameras may extend beyond the film's edge, resulting in invalid images. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a conductive thin film detection fixture to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a conductive thin film testing fixture, including a testing platform. A touch screen is fixedly mounted on the top surface of the testing platform via a bracket. An L-shaped testing frame is fixedly mounted on the top surface of the testing platform via bolts. The top end of the L-shaped testing frame is fixedly mounted on the back of the touch screen via bolts. A groove is formed on the bottom surface of the horizontal part of the L-shaped testing frame. Two corresponding adjusting plates are slidably connected to the inner wall of the groove. A motor is fixedly connected to one side of the L-shaped testing frame. A bidirectional lead screw is fixedly connected to the output end of the motor. Both adjusting plates are threadedly connected to the bidirectional lead screw. A mounting frame is fixedly connected to the bottom surface of each adjusting plate. A high-definition camera is slidably connected to the inner wall of the mounting frame. The top surface of the high-definition camera is in contact with the bottom surface of the adjusting plate. Springs are fixedly connected to both sides of the mounting frame. A locking pin is fixedly connected to the end of each spring away from the mounting frame. Both locking pins penetrate the mounting frame and engage with the housing of the high-definition camera.

[0007] Preferably, as described in any of the above embodiments, the high-definition camera has snap-fit ​​holes on both its left and right sides, and both snap-fit ​​pins penetrate the mounting frame and snap-fit ​​with the outer shell of the high-definition camera through the snap-fit ​​holes.

[0008] Preferably, in any of the above embodiments, the top surface of the high-definition camera is fixedly connected to two symmetrically arranged clamping plates, both of which are inserted into the bottom surface of the adjustment plate.

[0009] Preferably, one side of the mounting frame has a clearance groove, and a data cable is fixedly connected to one side of the high-definition camera. The data cable is located inside the clearance groove, and both high-definition cameras are electrically connected to the touch screen via the data cable.

[0010] Preferably, one side of the adjusting plate has a threaded hole, and both adjusting plates are threadedly connected to a bidirectional lead screw through the threaded hole.

[0011] Preferably, in any of the above embodiments, the inner wall of the groove is fixedly connected to two symmetrically arranged guide rods, the bidirectional lead screw is located between the two guide rods, and the adjusting plate is slidably connected to the guide rods.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. When inspecting conductive films of different widths, the operator issues a command via the touchscreen to start the motor. The motor output drives the bidirectional lead screw to rotate. Since both adjusting plates are threadedly connected to the bidirectional lead screw through threaded holes, and the adjusting plates are slidably connected to the guide rod on the inner wall of the groove, the rotation of the bidirectional lead screw drives the two adjusting plates to slide synchronously along the guide rod within the groove, thereby moving the high-definition camera within the mounting frame on the bottom of the adjusting plates. Based on the actual width of the conductive film, the operator precisely controls the rotation direction and angle of the motor via the touchscreen to adjust the distance between the two high-definition cameras until the camera's field of view completely covers the width of the conductive film being inspected. The motor is then turned off, completing the distance adjustment. This structure, through the cooperation of the motor, bidirectional lead screw, adjusting plates, and guide rod, replaces the traditional fixed installation design of high-definition cameras, achieving flexible and precise adjustment of the camera distance. No manual bolt removal is required; the adjustment process can be controlled solely via the touchscreen, avoiding production line interruptions and reliance on manual experience, significantly improving adjustment efficiency. Meanwhile, the guide rod ensures that the adjustment plate slides smoothly, prevents the high-definition camera from shifting, and ensures that the shooting range of the high-definition camera is free from overlap and blind spots after adjustment. This avoids wasting image processing resources on ineffective imaging and prevents defects from being missed. It effectively adapts to the detection needs of conductive films of different widths, improving the applicability and detection accuracy of the tooling.

[0013] 2. When installing the HD camera, first align the top plate of the HD camera with the bottom of the adjustment plate and insert it for initial positioning. Then slide the HD camera into the inner wall of the mounting frame, ensuring the top of the camera is flush with the bottom of the adjustment plate. During this process, the springs on both sides of the mounting frame will be compressed. Once the HD camera slides to the preset position, the springs will return to their original position, pushing the locking pins through the mounting frame and into the locking holes on both sides of the HD camera, thus securing the camera. Simultaneously, place the data cable on one side of the HD camera into the clearance groove of the mounting frame and electrically connect it to the touchscreen. For disassembly, simply pull the two locking pins outwards to compress the springs, disengaging the locking pins from the locking holes. This allows the HD camera to be pulled out of the mounting frame, and the data cable can be disconnected to complete the disassembly. The initial positioning is achieved through the insertion of the locking plate and the adjustment plate, combined with the locking mechanism of the springs and locking pins. This replaces the traditional bolt fixing method, eliminating the need for tools to tighten bolts during HD camera installation and removal. This simple and quick operation significantly reduces the difficulty and time cost of maintaining and replacing HD cameras. The clearance groove provides storage space for the data cable, preventing damage or tangling during installation and disassembly, and ensuring a stable electrical connection between the HD camera and the touchscreen. This design improves the efficiency of HD camera installation and disassembly, reduces wear and tear on components, and extends the lifespan of the tooling. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0017] like Figures 1 to 5 As shown, a conductive film testing fixture includes a testing platform 1. A touch screen 2 is fixedly mounted on the top surface of the testing platform 1 via a bracket. An L-shaped testing frame 3 is fixedly mounted on the top surface of the testing platform 1 via bolts. The top of the L-shaped testing frame 3 is fixedly mounted on the back of the touch screen 2 via bolts. A groove 4 is formed on the bottom surface of the horizontal part of the L-shaped testing frame 3. Two corresponding adjusting plates 5 are slidably connected to the inner wall of the groove 4. A motor 6 is fixedly connected to one side of the L-shaped testing frame 3. A bidirectional lead screw 7 is fixedly connected to the output end of the motor 6. Both adjusting plates 5 are threadedly connected to the bidirectional lead screw 7. A mounting frame 8 is fixedly connected to the bottom surface of each adjusting plate 5. A high-definition camera 9 is slidably connected to the inner wall of the mounting frame 8. The top surface of the high-definition camera 9 is in contact with the bottom surface of the adjusting plate 5. Springs 10 are fixedly connected to both the left and right sides of the mounting frame 8. A locking pin 11 is fixedly connected to the end of each spring 10 away from the mounting frame 8. Both locking pins 11 penetrate the mounting frame 8 and lock into the housing of the high-definition camera 9.

[0018] As an optional technical solution of this utility model, the high-definition camera 9 has snap-fit ​​holes 12 on both the left and right sides. Two snap-fit ​​pins 11 pass through the mounting frame 8 and snap-fit ​​with the outer shell of the high-definition camera 9 through the snap-fit ​​holes 12. This can securely snap the high-definition camera 9 into the mounting frame 8, preventing the high-definition camera 9 from loosening or shifting during tooling operation or adjustment, ensuring the stability of the high-definition camera 9's shooting position, and ensuring the clarity and accuracy of the detected image. At the same time, it provides convenience for the subsequent disassembly of the high-definition camera 9. The fixation can be released simply by pulling the snap-fit ​​pins 11, without complicated operation.

[0019] As an optional technical solution of this utility model, the top surface of the high-definition camera 9 is fixedly connected to two symmetrically arranged clamping plates 13. Both clamping plates 13 are inserted into the bottom surface of the adjustment plate 5, which can play a precise positioning role when installing the high-definition camera 9, quickly determine the installation position of the high-definition camera 9 under the adjustment plate 5, avoid installation offset affecting the shooting range, and further enhance the connection stability between the high-definition camera 9 and the adjustment plate 5, reduce the shaking of the high-definition camera 9 during use, and improve the detection accuracy.

[0020] As an optional technical solution of this utility model, a clearance groove 14 is provided through one side of the mounting frame 8, and a data cable 15 is fixedly connected to one side of the high-definition camera 9. The data cable 15 is located inside the clearance groove 14. Both high-definition cameras 9 are electrically connected to the touch screen 2 through the data cable 15. The clearance groove 14 provides storage space for the data cable 15 of the high-definition camera 9, which can prevent the data cable 15 from being squeezed, tangled or worn during the operation of the tooling, adjustment or installation and disassembly of the high-definition camera 9, ensuring the integrity of the data cable 15, ensuring the stable electrical connection between the high-definition camera 9 and the touch screen 2, avoiding interruption or abnormality of detection data transmission due to problems with the data cable 15, and maintaining the normal operation of the detection work.

[0021] As an optional technical solution of this utility model, a threaded hole 16 is provided through one side of the adjustment plate 5. Both adjustment plates 5 are threadedly connected to the bidirectional lead screw 7 through the threaded hole 16. When the bidirectional lead screw 7 rotates under the drive of the motor 6, the adjustment plate 5 can be moved along the bidirectional lead screw 7 through the threaded transmission, thereby realizing the adjustment of the spacing of the high-definition camera 9. The threaded connection method provides smooth and precise transmission, ensuring that the position of the adjustment plate 5 is controllable during the movement, ensuring the accuracy of the spacing adjustment of the high-definition camera 9, and adapting to the detection requirements of conductive films of different widths.

[0022] As an optional technical solution of this utility model, two symmetrically arranged guide rods 17 are fixedly connected to the inner wall of the groove 4. The bidirectional lead screw 7 is located between the two guide rods 17. The adjusting plate 5 is slidably connected to the guide rods 17, which can play a guiding and limiting role when the adjusting plate 5 moves with the bidirectional lead screw 7, preventing the adjusting plate 5 from rotating or deviating during the movement, ensuring that the adjusting plate 5 always slides smoothly along the preset direction, thereby ensuring the stability of the high-definition camera 9's movement trajectory, avoiding the overlap of the high-definition camera 9's shooting range or the appearance of blind spots due to the deviation of the adjusting plate 5, and improving the detection accuracy and tooling operation stability.

[0023] A conductive thin film testing fixture, the working principle of which is as follows: 1) When it is necessary to test conductive films of different widths, the operator issues a command through the touch screen 2 to start the motor 6, and the output of the motor 6 drives the bidirectional lead screw 7 to rotate.

[0024] 2): Both adjustment plates 5 are threadedly connected to the bidirectional lead screw 7 through threaded holes 16, and the adjustment plates 5 are slidably connected to the guide rod 17 on the inner wall of the groove 4. When the bidirectional lead screw 7 rotates, it will drive the two adjustment plates 5 to slide synchronously along the guide rod 17 in the groove 4, thereby driving the high-definition camera 9 in the mounting frame 8 on the bottom surface of the adjustment plates 5 to move.

[0025] 3): Based on the actual width of the conductive film, the rotation direction and angle of the motor 6 are precisely controlled by the touch screen 2, and the distance between the two high-definition cameras 9 is adjusted until the shooting range of the high-definition cameras 9 can completely cover the width of the conductive film to be tested.

[0026] In summary, this conductive film inspection fixture, through the cooperation of motor 6, bidirectional lead screw 7, adjusting plate 5, and guide rod 17, replaces the traditional fixed installation design of high-definition cameras, enabling flexible and precise adjustment of the spacing of high-definition cameras 9. No manual bolt removal is required; the adjustment process can be controlled solely through the touchscreen 2, avoiding production line interruptions and reliance on manual experience, significantly improving adjustment efficiency. Simultaneously, the guide rod 17 ensures smooth sliding of the adjusting plate 5, preventing the high-definition cameras 9 from shifting and ensuring that the shooting range of the high-definition cameras 9 after adjustment is free of overlap and blind spots. This avoids wasting image processing resources on ineffective imaging and prevents missed defects, effectively adapting to the inspection needs of conductive films of different widths, improving the applicability and inspection accuracy of the fixture. Initial positioning is achieved through the insertion of the clamping plate 13 and the adjusting plate 5, and the clamping and fixing with the spring 10 and the locking pin 11 replaces the traditional bolt fixing method. This eliminates the need for tools to tighten bolts when installing and removing the high-definition cameras 9, making operation simple and quick, and significantly reducing the difficulty and time cost of maintaining and replacing the high-definition cameras 9. The clearance groove 14 provides storage space for the data cable 15, preventing damage or tangling of the data cable 15 during installation and disassembly, and ensuring a stable electrical connection between the HD camera 9 and the touch screen 2. This design not only improves the efficiency of installing and disassembling the HD camera 9, but also reduces wear and tear on components and extends the service life of the tooling.
