Description

Technical Field

[0001] This invention relates to the field of insulating film testing technology, specifically to a testing device for insulating film production. Background Technology

[0002] The core function of insulating film is electrical isolation and safety protection. Placed between conductive components, it effectively blocks current, preventing equipment failures and safety hazards caused by high-voltage breakdown or short circuits. It ensures the stable operation of electronic equipment and electrical systems, significantly improving product lifespan and reliability. Insulating film is also an important application of new materials in the electrical field, using materials such as PI, PET, and PP to achieve special insulation. During the production process of insulating film, surface defect detection is required, necessitating the use of testing equipment. For example, the Chinese utility model patent application with application number 202220008604.0 and application date of 2022-01-04 describes an insulating film testing device. During operation, the electrical parameter tester can determine the presence of defects in the insulating film based on changes in electrical parameters between the first and second conductive parts, improving the efficiency of insulating film defect detection. The pressure regulating device further helps to more effectively detect openings and conductive particle inclusions on the insulating film. There is also a Chinese invention patent application with application number 202311051431.6 and application date of August 21, 2023, which discloses a quality inspection system for polyimide insulating film. During operation, this system collects data on the polyimide insulating film, removes dust from the film, detects its position to prepare for quality inspection, performs spectral analysis to determine its molecular structure, conducts thermal analysis to measure its mass and thermal properties at different temperatures to assess its thermal decomposition temperature and coefficient of thermal expansion, applies mechanical loads to measure deformation and record its toughness, and performs internal and external inspections to evaluate its flatness, smoothness, uniformity, and the presence of bubbles and cracks. The results are then fed back to the control module and displayed on a screen. During the testing process, since the insulating film is produced and stored in rolls, the surface to be tested is in a state of overlapping layers under natural conditions. Therefore, the insulating film needs to be unwound and wound up. During the winding process, it is necessary to ensure stable winding so that it does not become fluffy. If an efficient and stable winding component is not set up, the film roll will become fluffy, deviate, and have uneven ends. This will not only affect the appearance and insulation performance of the finished product, but also significantly reduce production efficiency due to frequent replacement of defective products. Summary of the Invention

[0003] The purpose of this invention is to provide a testing device for insulating film production, in order to solve the problem mentioned in the background art that the testing device for insulating film production does not have an efficient and stable winding component. Without an efficient and stable winding component, the film roll will become loose, misaligned, and uneven at the ends. This not only affects the appearance and insulation performance of the finished product, but also significantly reduces production efficiency due to frequent replacement of defective products.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a testing device for insulating film production, comprising a machine body, a working plate bolted to the upper surface of the machine body, and a long plate with a testing probe bolted to the front side of the working plate, and a slider connected to the surface of the working plate via an electric slide rail; a vertical plate fixedly connected to the upper surface of the machine body, and a take-up roller connected to the surface of the vertical plate via a drive motor, and an unwinding roller provided on the surface of the slider; a sliding plate slidably disposed on the surface of the vertical plate, and a pressure rod rotatably disposed inside the sliding plate, and a regularizing component disposed inside the sliding plate to regularly wind up the workpiece; a back plate fixedly connected to the back of the vertical plate, and a lubrication component disposed on the surface of the back plate to make the pressure rod work more smoothly; a connecting shaft rotatably disposed inside the vertical plate, and an auxiliary rod connected to the connecting shaft via a finishing component, and the auxiliary rod to make the workpiece wind up more evenly at the end of the test.

[0005] Preferably, the alignment component includes an outer plate fixedly connected to the surface of the vertical plate, and the slide plate is slidably disposed on the surface of the outer plate. In addition, an inner rod is fixedly connected to the inner wall of the slide plate, and the inner rod is symmetrically distributed on both sides of the slide plate.

[0006] Preferably, the inner rod passes through the interior of the outer plate, and the inner rod and the outer plate are slidably connected. A working spring is fixedly connected to the lower surface of the outer plate, and the other side of the working spring is fixedly connected to the inner wall of the slide plate.

[0007] Preferably, the lubrication assembly includes an airbag bonded to the surface of the back plate, a push rod fixedly connected to the surface of the slider, and a force-bearing plate corresponding to the push rod fixedly connected to the end of the connecting shaft.

[0008] Preferably, the force plate is initially in contact with the surface of the airbag, and a working tube is fixedly connected to the side of the airbag. The working tube is connected to the pressure rod through an external flexible tube. In addition, a through hole is opened on the surface of the pressure rod.

[0009] Preferably, a feed pipe is fixedly connected to the outside of the airbag, and a one-way valve is fixedly connected to both the surface of the feed pipe and the surface of the working pipe, and the through holes are distributed at equal angles on the surface of the pressure rod.

[0010] Preferably, a torsion spring is fixedly connected to the surface of the connecting shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the vertical plate.

[0011] Preferably, the finishing assembly includes a limiting rod fixedly connected to the inner wall of the vertical plate, and a movable plate is slidably disposed on the surface of the limiting rod, and the limiting rod is symmetrically distributed on both sides of the movable plate.

[0012] Preferably, a long pin is fixedly connected to the upper surface of the movable plate, and an upper connecting plate is fixedly connected to the upper surface of the other side of the movable plate. The surface of the upper connecting plate is provided with a mating groove, and the surface of the mating groove is inclined. A working rod is fixedly connected to the surface of the connecting shaft, and the working rod has an arc-shaped structure.

[0013] Preferably, the surface of the slider is fixedly connected to a top rod corresponding to the docking groove, the working rod is an elastic rod, and the end of the working rod is rotatably connected to the auxiliary rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: Employing a novel structural design, the testing equipment for insulating film production releases the workpiece via an unwinding roller and collects it via a winding roller. During this process, a detection probe inspects both the upper and lower sides of the workpiece. Furthermore, when the workpiece is wound up, it is squeezed by a pressure rod. Under the action of a working spring and an inner rod, the pressure rod has a continuous downward tendency, thus ensuring the workpiece is wound up smoothly. Additionally, the working rod and auxiliary rod are also in operation, ensuring that even the last workpiece is wound up smoothly. The specific details are as follows: (1) In the process of using the testing equipment for insulating film production, the workpiece is released by the unwinding roller and collected by the winding roller. During this process, the workpiece is tested on the upper and lower sides by the detection probe. During this process, when the workpiece on the winding roller becomes thicker, the pressure bar will be pushed. At this time, the pressure bar will slide on the surface of the inner rod, and the working spring will be squeezed. Under the action of the working spring and the inner rod, the pressure bar will always have a downward tendency, so that the workpiece is rolled up smoothly.

[0015] Furthermore, when the compression rod moves, the inner rod ensures that the compression rod only moves in the vertical direction, thus guaranteeing stability.

[0016] (2) During the testing process of the insulating film production testing equipment, as the workpiece on the unwinding roller gradually decreases, the slider slides to the left on the surface of the working plate under the action of the electric slide rail. Then the slider will push the force plate through the push rod, causing the force plate to drive the connecting shaft, working rod and auxiliary rod to rotate. Then the auxiliary rod also plays the role of smoothing the workpiece, so that the last part of the workpiece can be stably wound up.

[0017] Furthermore, when the slider drives the push rod to work, it also drives the push rod to work. At this time, the push rod will push the docking groove and the upper connecting plate, and then the upper connecting plate will drive the movable plate and the long pin to rise. At this time, the long pin will push the working rod, causing the working rod to bend, so that the auxiliary rod can fit deeply with the workpiece, that is, the smoothing effect of the auxiliary rod is better.

[0018] (3) In the testing equipment for producing insulating film, when the force plate is pushed to rotate by the push rod, the force plate will squeeze the air bag. At this time, the air bag will supply lubricating oil to the pressure rod through the working tube. The pressure rod sprays lubricating oil through the through hole, so that the pressure rod rotates more smoothly inside the slide plate and will not get stuck.

[0019] Furthermore, when the airbag is not compressed, it inflates by drawing air through the feed pipe. During the compression and expansion of the airbag, the one-way valve directs the material flow from the feed pipe to the pressure rod, preventing backflow and ensuring the stability of the lubricating oil operation. In addition, when the material inside the airbag is depleted, it can be replenished through the feed pipe. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-11 The present invention provides the following technical solution: a testing device for insulating film production.

[0024] Example 1: By using a pre-formed component, the workpiece can be wound up more smoothly during inspection, such as... Figures 1-5 As shown, the machine includes a body 1, a work plate 2 bolted to the upper surface of the body 1, and a long plate with a detection probe bolted to the front side of the work plate 2. A slider 3 is connected to the surface of the work plate 2 via an electric slide rail. A vertical plate 4 is fixedly connected to the upper surface of the body 1, and a take-up roller is connected to the surface of the vertical plate 4 via a drive motor. In addition, an unwinding roller is provided on the surface of the slider 3. A slide plate 6 is slidably disposed on the surface of the vertical plate 4. A pressure rod 7 is rotatably disposed inside the slide plate 6. A straightening component is disposed inside the slide plate 6 to straighten the workpiece. The straightening component includes an outer plate 5 fixedly connected to the surface of the vertical plate 4. The slide plate 6 is slidably disposed on the surface of the outer plate 5. An inner rod 8 is fixedly connected to the inner wall of the slide plate 6. In addition, the inner rod 8 is symmetrically distributed on both sides of the slide plate 6.

[0025] The inner rod 8 passes through the interior of the outer plate 5, and the inner rod 8 and the outer plate 5 are slidably connected. A working spring 9 is fixedly connected to the lower surface of the outer plate 5. In addition, the other side of the working spring 9 is fixedly connected to the inner wall of the slide plate 6.

[0026] During operation, the workpiece is released by the unwinding roller and collected by the winding roller. During this process, a detection probe inspects the workpiece from both the top and bottom. When the probe is working, a CCD / CMOS image sensor converts the light signal from the film surface into an electrical signal, dividing the image into tiny regions and comparing it with the grayscale (brightness / darkness) of the surrounding areas. If the difference exceeds a threshold, it is determined to be a defect. Subsequently, an algorithm extracts the defect features (such as size and location) and outputs the results. Simultaneously, as the workpiece on the winding roller becomes thicker, the pressure rod 7 is pushed. At this point, the pressure rod 7 slides on the surface of the inner rod 8, causing the working spring 9 to be compressed. Under the action of the working spring 9 and the inner rod 8 (the inner rod 8 ensures that the pressure rod 7 moves only vertically during movement, guaranteeing stability), the pressure rod 7 tends to move downwards, thus ensuring that the workpiece is wound up smoothly and evenly.

[0027] Example 2: Unlike Example 1, the lubrication assembly allows the pressure rod 7 to be lubricated at the end of its operation, facilitating its operation during subsequent testing. Figures 6-10 The back plate 10 is fixedly connected to the back of the vertical plate 4, and the surface of the back plate 10 is provided with a lubrication component to make the pressure rod 7 work more smoothly. The lubrication component includes an air bag 11 bonded to the surface of the back plate 10, a push rod 18 fixedly connected to the surface of the slider 3, and a force plate 14 corresponding to the push rod 18 fixedly connected to the end of the connecting shaft 13.

[0028] Initially, the force plate 14 is in contact with the surface of the airbag 11, and the working tube 12 is fixedly connected to the side of the airbag 11. The working tube 12 is connected to the pressure rod 7 through an external hose. In addition, the surface of the pressure rod 7 is provided with a through hole 26.

[0029] An inlet pipe 19 is fixedly connected to the outside of the airbag 11, and a one-way valve is fixedly connected to both the surface of the inlet pipe 19 and the surface of the working pipe 12. The through holes 26 are distributed at equal angles on the surface of the pressure rod 7. A torsion spring 15 is fixedly connected to the surface of the connecting shaft 13, and the other side of the torsion spring 15 is fixedly connected to the inner wall of the vertical plate 4.

[0030] During the testing process, as the work progresses to the later stages, the number of workpieces on the unwinding roller decreases. At this point, the slider 3, under the action of the electric slide rail, slides to the left on the surface of the working plate 2. Subsequently, the slider 3 pushes the force plate 14 through the push rod 18, causing the force plate 14 to drive the connecting shaft 13 to rotate. At this time, the force plate 14 will squeeze the air bladder 11. The air bladder 11 will supply lubricating oil to the pressure rod 7 through the working pipe 12. The pressure rod 7 sprays oil through the through hole 26, reducing the friction between itself and the slide plate 6, making the pressure rod 7 rotate more smoothly inside the slide plate 6 and preventing jamming. When the air bladder 11 is not squeezed, the air bladder 11 inflates by drawing air through the feed pipe 19. During the process of the air bladder 11 being squeezed and inflated, the one-way valve ensures that the material flows from the feed pipe 19 to the pressure rod 7, preventing backflow and ensuring the stability of the lubricating oil operation. In addition, when the material inside the air bladder 11 is consumed, it can be replenished through the feed pipe 19.

[0031] Example 3: Unlike Example 2, the finishing assembly allows the workpiece to be smoothly rolled up even after the inspection process, such as... Figures 9-11 As shown, the connecting shaft 13 is rotatably disposed inside the vertical plate 4, and the connecting shaft 13 is connected to the auxiliary rod 17 through the tailing assembly. The auxiliary rod 17 makes the workpiece more evenly rolled up when the inspection is finished. The tailing assembly includes a limiting rod 21 fixedly connected to the inner wall of the vertical plate 4, and a movable plate 20 is slidably disposed on the surface of the limiting rod 21. The limiting rod 21 is symmetrically distributed on both sides of the movable plate 20.

[0032] A long pin 25 is fixedly connected to the upper surface of the movable plate 20, and an upper connecting plate 23 is fixedly connected to the upper surface of the other side of the movable plate 20. The surface of the upper connecting plate 23 is provided with a docking groove 24. In addition, the surface of the docking groove 24 is inclined. A working rod 16 is fixedly connected to the surface of the connecting shaft 13. The working rod 16 has an arc structure. A top rod 22 corresponding to the docking groove 24 is fixedly connected to the surface of the slider 3. The working rod 16 is an elastic rod, and the end of the working rod 16 is rotatably connected to the auxiliary rod 17.

[0033] When slider 3 pushes the force plate 14 via push rod 18, the force plate 14 causes the connecting shaft 13, working rod 16, and auxiliary rod 17 to rotate. The auxiliary rod 17 rotates to contact and smooth the insulating film, thus also smoothing the workpiece, allowing the last section of the workpiece to be stably wound up. When slider 3 drives push rod 18 to work, it also drives push rod 22 to work. At this time, push rod 22 pushes docking groove 24 and upper connecting plate 23, which in turn drives upper connecting plate 23 to move movable plate 20 and long pin 25 upward (when movable plate 20 moves, limit rod 21 makes movable plate 20 move only in the vertical direction). At this time, long pin 25 pushes working rod 16, causing working rod 16 to bend 9 (e.g., Figure 11As shown in the figure, the working rod 16 can then drive the auxiliary rod 17 to rotate further. At this time, the auxiliary rod 17 can fit closely to the workpiece, that is, the smoothing effect of the auxiliary rod 17 is better.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
