Description

Technical Field

[0001] This utility model relates to the field of automotive film perforation technology, and in particular to an automotive film perforation tool. Background Technology

[0002] Automotive film punching tools are specialized punching equipment designed for the characteristics of automotive film materials. Their core function is to quickly and accurately process holes that meet the size requirements without damaging the original structure of the film or producing burrs or wrinkles, supporting the production and service needs of multiple scenarios such as automotive film modification and original factory film pre-installation.

[0003] Automotive membrane drilling tools can meet basic drilling needs. Their targeted structural design avoids problems such as membrane tearing and uneven hole edges that occur with traditional general-purpose drills. However, in actual use, the tools lack effective anti-shake and positioning assistance mechanisms. They rely entirely on the operator's hand to hold the drill shank and apply axial pressure to complete the drilling. During the process, the multi-stage convex structure of the reaming section of the stepped drill bit generates intermittent radial reaction force. This reaction force is transmitted to the operator's hand through the drill shank. If the operator's hand strength is uneven or fatigue occurs due to continuous holding, it will cause involuntary hand shaking, which will cause the drill bit to deviate from the preset hole center, resulting in hole offset or enlargement of the hole diameter. Ultimately, this leads to a deviation between the punched hole and the preset position. Especially when processing small-diameter holes, this deviation may even exceed the allowable error range of the hole position, failing to meet the requirements of high-precision drilling. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides an automotive membrane drilling tool, which aims to improve the problem in the prior art where uneven hand strength control or fatigue caused by continuous gripping by the operator can lead to involuntary hand shaking, causing the drill bit to deviate from the preset hole center, resulting in hole displacement or hole diameter enlargement, thus failing to meet the requirements of high-precision drilling.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-4 An embodiment of this utility model is provided: an automotive film opening tool, including a fixing frame 1, with sliding grooves 2 on both the front and rear sides of the fixing frame 1, and a precision mechanism 3 inside the sliding grooves 2 for precise opening; a chip blowing mechanism 4 is provided on the front side of the fixing frame 1 for chip blowing. The precision mechanism 3 includes a telescopic rod 31. The right side of the telescopic rod 31 is fixedly connected to the right side of the rear slide groove 2. Slider 32 is slidably connected inside both slide grooves 2. The right side of the rear slider 32 is fixedly connected to the left side of the telescopic rod 31. Two fixed rods 311 are fixedly connected between adjacent sliders 32. The outer walls of the two fixed rods 311 are slidably connected to the same moving block 33. A fixed plate 34 is provided on the right side of the moving block 33. A motor 35 is fixedly connected to the top of the fixed plate 34. The output end of the motor 35 passes through the top of the fixed plate 34. A cutting blade 36 is fixedly connected to the output end of the motor 35. Limiting components 37 are provided on the upper and lower sides of the two sliders 32. Friction reduction components 38 are provided on the upper and lower sides of the two limiting components 37. An adjustment component 39 is provided on the right side of the moving block 33. Clamping components 310 are provided on the left and right sides of the interior of the fixed frame 1. Specifically, when the precision mechanism 3 is needed to open the car film, the car film is first clamped at the bottom of the inner side of the fixing frame 1 by the clamping components 310 on the left and right sides inside the fixing frame 1; by the cooperation between the clamping components 310 and the fixing frame 1, the position of the car film in the fixing frame 1 is limited, so as to avoid the car film from shifting during the opening process, thus providing a basis for precise opening. Then adjust the lateral position of the cutting blade 36: activate the telescopic rod 31. When the telescopic rod 31 extends or retracts, it drives the rear slider 32 to slide left and right along the rear slide groove 2. Since the two sliders 32 are connected by the fixed rod 311, when the rear slider 32 moves, it drives the front slider 32 to slide synchronously along the front slide groove 2. Through the cooperation of the telescopic rod 31 and the slider 32, the movement of the slider 32 is powered, realizing the directional sliding of the slider 32. At the same time, the limiting components 37 on the upper and lower sides of the slider 32 restrict the movement direction of the slider 32, ensuring that the slider 32 can only slide left and right along the slide groove 2, avoiding the slider 32 from deviating. The friction reduction component 38 reduces the friction between the slider 32 and the groove 2, ensuring smooth sliding of the slider 32. Through the cooperation of the limiting component 37 and the friction reduction component 38, the stability and smoothness of the slider 32's movement are improved. The slider 32 drives the fixed rod 311 to move synchronously, and the fixed rod 311 drives the moving block 33 to move synchronously. The moving block 33 drives the motor 35 and the cutting blade 36 to move synchronously through the fixed plate 34 until the cutting blade 36 moves directly above the position where the automotive film is to be opened. Through the cooperation of the fixed rod 311 and the moving block 33, the movement of the slider 32 is transmitted to the cutting blade 36, realizing the precise adjustment of the lateral position of the cutting blade 36. Next, the height of the cutting blade 36 is adjusted by the adjustment component 39 on the right side of the moving block 33: by operating the adjustment component 39, the adjustment component 39 drives the fixed plate 34 to move up and down, and the fixed plate 34 drives the motor 35 to move up and down synchronously with the cutting blade 36; by cooperating with the adjustment component 39 and the fixed plate 34, the height of the cutting blade 36 is adjusted so that the bottom of the cutting blade 36 contacts the surface of the automotive film or maintains a preset distance, so as to meet the opening requirements of automotive films of different thicknesses; After the position of the cutting blade 36 is adjusted, the motor 35 is started, and the output of the motor 35 drives the cutting blade 36 to rotate at high speed. Through the cooperation between the motor 35 and the cutting blade 36, the cutting blade 36 is provided with rotational power, enabling it to cut automotive film. The cutting blade 36 is continuously controlled to move downward through the adjusting component 39, and it contacts the automotive film to cut and create a hole. During the hole-making process, the position of the slider 32 can be finely adjusted through the telescopic rod 31 to further ensure the accuracy of the hole-making position. The debris generated during the drilling process is removed by the debris blowing mechanism 4 to prevent debris from accumulating and affecting the drilling accuracy or adhering to the surface of the car film. After the drilling is completed, the motor 35 is turned off, and the cutting blade 36 is controlled to move upward and detach from the car film by the adjusting component 39. Then, the clamping component 310 is used to release the clamping of the car film and remove the car film after drilling. When maintaining the precision mechanism 3, check the telescopic performance of the telescopic rod 31 to ensure it can stably drive the slider 32 to move; check the fit between the slider 32 and the slide groove 2, and clean the impurities inside the slide groove 2; check the wear of the friction reduction component 38 and replace any faulty friction reduction component 38; check the adjustment accuracy of the adjustment component 39 to ensure the height adjustment of the cutting blade 36 is accurate; check the clamping force of the clamping component 310 to ensure it can stably clamp the automotive film, thus achieving precise opening of the automotive film and ensuring the accuracy and stability of the opening operation.

[0019] Reference Figures 1-5 The chip blowing mechanism 4 includes multiple fans 42. The outer walls of the multiple fans 42 are fixedly connected to the front interior of the fixed frame 1. Multiple air inlets 41 are opened on the front side of the fixed frame 1. The outer walls of the multiple fans 42 are respectively fixedly connected to the interior of the multiple air inlets 41. A chip outlet 43 is opened on the rear interior side of the fixed frame 1. A collection box 44 is installed on the rear side of the fixed frame 1. Mounting components 45 are provided on both the left and right sides of the collection box 44. Specifically, before the precision mechanism 3 performs the opening operation on the car film, the collection box 44 is first installed on the rear side of the fixing frame 1 through the mounting components 45 on the left and right sides of the collection box 44, so that the opening of the collection box 44 is aligned with the chip outlet 43 on the rear side of the fixing frame 1; through the cooperation of the mounting components 45, the collection box 44, and the fixing frame 1, it is ensured that the collection box 44 is firmly connected to the fixing frame 1, and the collection box 44 can accurately receive the debris discharged from the chip outlet 43, providing a stable container for debris collection; Before starting the motor 35 of the precision mechanism 3, start the multiple fans 42 of the chip blowing mechanism 4. When the fans 42 are running, they draw in air from the outside through the air inlet 41 on the front side of the fixed frame 1 to form an airflow. Through the cooperation of the fans 42 and the air inlet 41, the airflow can be stably entered into the fixed frame 1 to provide power for blowing away debris. The airflow flows inside the fixed frame 1 and moves towards the chip outlet 43 on the rear side of the fixed frame 1 to form a directional airflow channel. Then, the precision mechanism 3 begins to make holes: the clamping component 310 fixes the car film to the bottom inside of the fixing frame 1, the adjusting component 39 adjusts the height of the cutting blade 36 to a suitable position, the motor 35 drives the cutting blade 36 to rotate, the telescopic rod 31 pushes the slider 32 to slide along the slide groove 2, the slider 32 drives the moving block 33, the fixing plate 34 and the cutting blade 36 to move synchronously, the cutting blade 36 contacts the car film and makes holes; the debris generated during the hole-making process is blown towards the debris outlet 43 by the directional airflow inside the fixing frame 1; through the cooperation of the airflow and the debris outlet 43, the debris is guided to move towards the collection box 44, so as to avoid the debris from accumulating inside the fixing frame 1 or adhering to the surface of the car film and affecting the hole-making accuracy; Debris enters the collection box 44 through the debris outlet 43, where it is collected and stored. The cooperation between the debris outlet 43 and the collection box 44 ensures that all debris generated during the drilling process enters the collection box 44, preventing debris from scattering into the external environment and causing pollution. After drilling is completed, the fan 42 and motor 35 are turned off, and the collection box 44 is disassembled using the mounting component 45 to clean the debris inside. After cleaning, the collection box 44 can be reinstalled back onto the rear of the mounting bracket 1 using the mounting component 45, in preparation for the next drilling operation. When maintaining the blow-off mechanism 4, check the connection status between the fan 42 and the air inlet 41 to ensure stable operation of the fan 42; clean the impurities inside the air inlet 41 to avoid blockage affecting airflow intake; check the unobstructed status of the discharge port 43 and clean out any residual debris inside the discharge port 43; check the fit between the mounting component 45, the collection box 44, and the fixing bracket 1 to ensure stable installation and removal of the collection box 44; check the integrity of the collection box 44 to ensure no damage leading to debris leakage. This achieves efficient blowing and centralized collection of debris during the automotive film perforation process, ensuring perforation accuracy and a clean operating environment, and providing support for the stable use of automotive film perforation tools.

[0020] Reference Figures 3-4 The limiting component 37 includes multiple limiting blocks 371, which are fixedly connected to the upper and lower sides of the two sliders 32 respectively. Limiting grooves 372 are provided on the upper and lower sides of the two slide grooves 2. The friction reduction component 38 includes multiple fixing blocks 381, which are fixedly connected to the opposite side of the multiple limiting blocks 371 respectively. A ball bearing 382 is rotatably connected to the adjacent fixing blocks 381. The adjusting component 39 includes a slide rail 391, which is fixedly connected to the right side of the moving block 33 on the left side. A connecting plate 392 is slidably connected to the top right side of the slide rail 391. A support block 394 is fixedly connected to the bottom of the slide rail 391. A telescopic rod 393 is fixedly connected to the top right side of the support block 394. The top of the telescopic rod 393 is fixedly connected to the bottom of the connecting plate 392. Specifically, when the limiting component 37 and the friction reduction component 38 are in operation, the telescopic rod 31 of the precision mechanism 3 pushes the slider 32 to slide along the slide groove 2. The limiting blocks 371 on the upper and lower sides of the slider 32 move synchronously with the slider 32, and the limiting blocks 371 are embedded in the limiting grooves 372 on the upper and lower sides of the slide groove 2. Through the cooperation of the limiting blocks 371 and the limiting grooves 372, the sliding direction of the slider 32 is limited, ensuring that the slider 32 can only slide left and right along the slide groove 2, avoiding vertical displacement of the slider 32 during sliding, and ensuring the movement of the cutting blade 36. The tracking is precise. Meanwhile, the fixed block 381 on the side away from the limiting block 371 moves with the limiting block 371. The rotating ball 382 between the fixed blocks 381 contacts and rolls with the inner wall of the limiting groove 372. Through the cooperation between the rotating ball 382 and the fixed block 381, the sliding friction between the limiting block 371 and the limiting groove 372 is converted into rolling friction. Through the cooperation between the rotating ball 382 and the limiting groove 372, the resistance of the slider 32 when sliding is reduced, ensuring that the slider 32 drives the cutting blade 36 to move smoothly and improving the smoothness of the hole opening operation. When adjusting component 39 is in operation, the height of the cutting blade 36 needs to be adjusted to accommodate different thicknesses of automotive film or different opening requirements. Telescopic rod 393 is then activated. As telescopic rod 393 extends, it pushes connecting plate 392 upwards along the top right side of slide rail 391. Connecting plate 392 connects to fixed plate 34, causing fixed plate 34, motor 35, and cutting blade 36 to move upwards synchronously. Through the cooperation of telescopic rod 393 and connecting plate 392, the telescopic force of telescopic rod 393 is converted into vertical movement of cutting blade 36, achieving an upward adjustment of the cutting blade 36's height. When the second telescopic rod 393 retracts, it pulls the connecting plate 392 to slide downwards along the slide rail 391, causing the cutting blade 36 to move downwards synchronously, thus adjusting the height of the cutting blade 36. Through the cooperation between the slide rail 391 and the connecting plate 392, the movement direction of the connecting plate 392 is limited, ensuring that the cutting blade 36 can only move vertically, avoiding deviation during height adjustment. Through the cooperation between the support block 394 and the slide rail 391, it provides stable support for the second telescopic rod 393, ensuring that the second telescopic rod 393 can stably push or pull the connecting plate 392, achieving precise height adjustment of the cutting blade 36. After the height of the cutting blade 36 is adjusted, the clamping assembly 310 fixes the automotive film, the motor 35 and the fan 42 of the blowing mechanism 4 are started, the telescopic rod 31 pushes the slider 32 to move, and the cutting blade 36 makes the hole. The limiting assembly 37, the friction reduction assembly 38 and the adjusting assembly 39 work together to ensure that the cutting blade 36 moves accurately, smoothly and at the correct height. During maintenance, the fit between the limiting block 371 and the limiting groove 372 can be checked, and impurities in the groove can be cleaned. The rotation status of the ball bearing 382 can be checked, and any stuck ball bearing 382 can be replaced. The sliding status between the slide rail 391 and the connecting plate 392 can be checked, and impurities inside the slide rail 391 can be cleaned. The telescopic performance of the telescopic rod 393 can be checked to ensure stable height adjustment. This further improves the accuracy and smoothness of the hole-making tool and ensures the quality and efficiency of the automotive film hole-making.

[0021] Reference Figures 1-5 The clamping assembly 310 includes two fixing bars 3101. The outer walls of the two fixing bars 3101 are respectively fixedly connected to the left and right sides of the inside of the fixing frame 1. The top front and rear sides of the two fixing bars 3101 are threadedly connected to threaded rods 3102. The bottom of the outer walls of the multiple threaded rods 3102 are fixedly connected to bearings 3103. The bottom of the multiple bearings 3103 is fixedly connected to clamping plates 3104. The mounting assembly 45 includes mounting plates 451. The adjacent mounting plates 451 are respectively fixedly connected to the left and right sides of the collection box 44. The rear sides of the multiple mounting plates 451 are threadedly connected to bolts 452. The top of the moving block 33 is fixedly connected to a fixing post 5. The top of the fixing post 5 is fixedly connected to a top plate 6. Specifically, when the clamping assembly 310 operates, the automotive film is placed on the inner bottom of the fixing frame 1, aligning the opening position of the automotive film with the lower part of the cutting blade 36; the threaded rod 3102 on the front and rear sides of the top of the fixing strip 3101 is rotated, and the threaded rod 3102 moves downward along the threaded hole of the fixing strip 3101; through the cooperation between the threaded rod 3102 and the fixing strip 3101, the directional movement of the threaded rod 3102 is achieved, driving the bottom bearing 3103 and the clamping plate 3104 to move downward synchronously, and the clamping plate 3104 gradually approaches the surface of the automotive film until the clamping plate 3104 completely adheres to the automotive film and applies pressure; through the clamping plate 3103... 04. In conjunction with the car film, the car film is fixed to the bottom inner side of the fixing frame 1 to prevent displacement of the car film during the drilling process, which would affect the drilling accuracy. Through the cooperation of the bearing 3103 with the threaded rod 3102 and the clamping plate 3104, when the threaded rod 3102 rotates, the bearing 3103 can reduce the friction between the threaded rod 3102 and the clamping plate 3104, and prevent the clamping plate 3104 from rotating with the threaded rod 3102, which would cause wear on the surface of the car film. This achieves non-destructive fixing of the car film. When the car film needs to be removed, the threaded rod 3102 is rotated in the opposite direction, which drives the clamping plate 3104 to move upward and detach from the car film, thus completing the removal of the car film. When the mounting component 45 is in operation, when installing the collection box 44, align the opening of the collection box 44 with the chip outlet 43 on the rear side of the fixing frame 1, so that the mounting plates 451 on the left and right sides of the collection box 44 are in contact with the rear side of the fixing frame 1; rotate the bolt 452 on the rear side of the mounting plate 451, and the bolt 452 moves forward along the threaded hole of the mounting plate 451 until the front end of the bolt 452 is in close contact with the rear side of the fixing frame 1 and is tightened; through the cooperation of the bolt 452 and the mounting plate 451, the mounting plate 451 is fixed to the rear side of the fixing frame 1, thereby realizing a stable connection between the collection box 44 and the fixing frame 1, ensuring that the collection box 44 can stably receive the debris discharged from the chip outlet 43. When the collection box 44 needs to be cleaned, rotate the bolt 452 in the opposite direction so that the front end of the bolt 452 is disengaged from the fixing frame 1, and the collection box 44 can be removed from the rear side of the fixing frame 1. After cleaning, it can be fixed again by the bolt 452. The operation is convenient. When the fixed column 5 and the top plate 6 are in operation, the top plate 6 at the top of the fixed column 5 moves synchronously with the moving block 33. Through the cooperation between the fixed column 5 and the moving block 33, the top plate 6 provides support for the top structure of the moving block 33, enhancing the overall structural stability of the moving block 33. When the adjusting component 39 adjusts the height of the cutting blade 36 or the slider 32 drives the moving block 33 to slide, the top plate 6 can prevent the moving block 33 from deforming due to uneven force. Through the cooperation between the top plate 6 and the fixed column 5, the accuracy of the moving trajectory of the cutting blade 36 and the stability of the height adjustment are indirectly guaranteed. During maintenance, the thread fit between the threaded rod 3102 and the fixing strip 3101 can be checked, and impurities in the threaded area can be cleaned; the integrity of the clamping plate 3104 can be checked, and worn clamping plates 3104 can be replaced; the connection status between the bolt 452 and the mounting plate 451 can be checked to ensure that the collection box 44 is firmly fixed; the connection status between the fixing post 5 and the moving block 33 and the top plate 6 can be checked to ensure that there is no looseness. This achieves stable fixing of the car film, convenient disassembly and assembly of the collection box 44, and auxiliary support of the moving block 33, further improving the practicality and stability of the hole-opening tool and ensuring the smooth operation of the car film hole-opening operation.

[0022] Working principle: The collection box 44 is installed on the rear side of the fixing frame 1 using the mounting components 45 on its left and right sides, aligning the opening of the collection box 44 with the chip outlet 43 on the rear side of the fixing frame 1. The bolt 452 on the rear side of the mounting plate 451 is rotated, moving forward along the threaded hole until its front end is in tight contact with and secured to the rear side of the fixing frame 1. Through the cooperation of the bolt 452 and the mounting plate 451, the collection box 44 is stably fixed to the rear side of the fixing frame 1, ensuring accurate chip collection and providing a stable container for subsequent chip collection. The second step involves clamping the automotive film and placing it at the bottom inner side of the fixing frame 1. Align the opening position with the bottom of the cutting blade 36; rotate the threaded rod 3102 on the front and rear sides of the top of the fixing strip 3101 in the clamping assembly 310. The threaded rod 3102 moves downward along the threaded hole of the fixing strip 3101, driving the bearing 3103 at the bottom and the clamping plate 3104 downward synchronously; the clamping plate 3104 gradually fits against the car film and applies pressure. The car film is fixed by the cooperation between the clamping plate 3104 and the car film, avoiding displacement when opening the hole; the bearing 3103 reduces the friction between the threaded rod 3102 and the clamping plate 3104, preventing the clamping plate 3104 from wearing the car film as it rotates with the threaded rod 3102, thus achieving non-destructive fixing of the car film and completing the preliminary preparation; After the initial preparation, the position adjustment stage of the cutting blade 36 begins: First, the lateral position is adjusted, and the telescopic rod 31 of the precision mechanism 3 is activated. The extension or retraction of the telescopic rod 31 causes the rear slider 32 to slide along the rear slide groove 2. Since the two sliders 32 are connected by the fixed rod 311, the rear slider 32 causes the front slider 32 to slide synchronously along the front slide groove 2. The limiting components 37 on the upper and lower sides of the slider 32 operate, and the limiting block 371 moves with the slider 32 and is embedded in the limiting groove 372. Through the limiting block 371 and the limiting... The groove 372 restricts the slider 32 to slide only left and right, preventing deviation. The friction-reducing components 38 on the upper and lower sides of the limiting component 37 operate synchronously. The fixed block 381 moves with the limiting block 371, and the rotating ball 382 rolls against the inner wall of the limiting groove 372, converting sliding friction into rolling friction, reducing the sliding resistance of the slider 32, and ensuring smooth sliding. The slider 32 drives the fixed rod 311 to move, and the fixed rod 311 drives the moving block 33 to move synchronously. The moving block 33 drives the motor 35 via the fixed plate 34. The cutting blade 36 moves until it is directly above the opening position of the automotive film, achieving precise horizontal position adjustment. Then, the height is adjusted, and the adjustment component 39 on the right side of the moving block 33 is activated. The telescopic rod 393 extends to push the connecting plate 392 to slide upward along the slide rail 391, or retracts to pull the connecting plate 392 downward. The connecting plate 392 drives the fixing plate 34, motor 35, and cutting blade 36 to move up and down synchronously. The slide rail 391 limits the connecting plate 392 to move only vertically to prevent the cutting blade 36 from deviating. The support block 394 provides stable support for the telescopic rod 393, ensuring that it can stably push or pull the connecting plate 392, so that the bottom of the cutting blade 36 contacts the surface of the automotive film or maintains a preset distance, adapting to different thicknesses of automotive film, and completing the position adjustment of the cutting blade 36. At the same time, the fixing column 5 at the top of the moving block 33 drives the top plate 6 to move synchronously. The top plate 6 provides support for the moving block 33, enhancing its structural stability and preventing uneven deformation of the moving block 33, indirectly ensuring the accuracy of the cutting blade 36 position adjustment. The motor 35 and the fan 42 of the chip blowing mechanism 4 are started. The output of the motor 35 drives the cutting blade 36 to rotate at high speed. The motor 35 and the cutting blade 36 work together to provide rotational power to the cutting blade 36, enabling it to cut. The telescopic rod 393 of the adjustment component 39 is continuously activated to control the cutting blade 36 to move downward. The cutting blade 36 contacts the automotive film and cuts an opening. During the opening process, the position of the slider 32 can be finely adjusted by the telescopic rod 31 to further ensure the accuracy of the opening position. The chip blowing mechanism 4 operates synchronously. The fan 42 draws in air through the air inlet 41 on the front side of the fixed frame 1 to form an airflow. The airflow flows into the chip outlet 43 inside the fixed frame 1 to form a directional channel. The chips generated during the opening are blown towards the chip outlet 43 by the airflow and enter the collection box 44 through the chip outlet 43. The collection box 44 collects the chips. The cooperation between the airflow and the chip outlet 43 prevents the accumulation of chips from affecting the opening accuracy or polluting the environment, thus completing the opening operation. Turn off motor 35 and fan 42, start telescopic rod 393 of adjustment component 39, control the cutter 36 to move upward and detach from the car film; rotate the threaded rod 3102 of clamping component 310 in the opposite direction, drive clamping plate 3104 to move upward and detach from the car film, release the clamp, and take out the car film after drilling; rotate the bolt 452 of mounting component 45 in the opposite direction, so that the front end of bolt 452 is detached from the fixing frame 1, remove the collection box 44 to clean the internal debris, and after cleaning, reinstall the collection box 44 back to the rear of the fixing frame 1 through bolt 452 to prepare for the next drilling, and complete the final finishing. When maintaining the precision mechanism 3, check the telescopic performance of telescopic rod 31 to ensure stable driving of slider 32; clean impurities inside slide groove 2 and check the fit between slider 32 and slide groove 2; check the rotation status of ball bearing 382 and replace any stuck ball bearing 382; check the telescopic performance of telescopic rod 393 and the cleanliness of slide rail 391 to ensure accurate height adjustment of cutting blade 36; check the thread fit between threaded rod 3102 and fixing strip 3101, clean impurities, and replace worn clamping plate 3104. When maintaining the chip blowing mechanism 4, check the connection status between fan 42 and air inlet 41 to ensure stable operation of fan 42; clean impurities inside air inlet 41 and chip outlet 43 to ensure unobstructed flow; check the integrity of collection box 44 to ensure no damage. When maintaining auxiliary components, check the connection status between fixing column 5, moving block 33, and top plate 6 to ensure no looseness. This achieves precise opening of automotive film, ensuring opening accuracy, smooth operation, and a clean environment, providing comprehensive support for the stable use of automotive film opening tools.
