Description

Technical Field

[0001] This application relates to the technical field of automotive parts, and in particular to an online inspection device for the installation of adhesive strips on automotive parts. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. There are many types of automotive parts. As people's living standards improve, people's consumption of cars is also increasing, and the entire market for automotive parts is also growing. In recent years, automotive parts manufacturers have also been developing rapidly. Automotive parts are diverse in type. Automotive parts are usually manufactured by manufacturers and then transported to car manufacturers for assembly.

[0003] For automotive parts, screws, nuts, hand-applied adhesive strips, and hand-assembled clips that require welding are often key control targets for preventing leaks and rework. The most traditional inspection method is manual inspection, where inspectors compare each part with a sample and perform a 100% visual inspection by scribing lines on each part before packaging. This inspection method requires a high degree of attention to detail and a good work attitude from the inspectors. If their work attitude is poor or they are careless, it will lead to the leakage of defective products. It can be seen that traditional manual inspection is not conducive to the quality control of large-volume products. Therefore, in order to ensure the efficiency of the inspection of hand-applied adhesive strips and hand-assembled clips on automotive parts, sensors are usually used for inspection.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: For traditional automatic inspection devices, the most common sensors used are contact sensors. In actual operation, they are often fixed at specific positions on welding fixtures or inspection blocks where products are placed to detect whether standard parts are missing from welding or assembly. Contact sensors typically consist of a metal probe and a housing. When the probe comes into direct contact with the object being tested, it can detect the object and transmit a corresponding signal. This type of detection is based on "physical contact." The drawback is that when operators pick up and put down products, the products are prone to bumping against the sensor probe. Long-term bumping may cause the sensor to become insensitive, and the sensor may also fall off its fixed position. Therefore, this type of automatic inspection device requires regular maintenance. Summary of the Invention

[0005] To address the drawback of contact sensors, which rely on "physical contact" and are prone to collisions between the product and the sensor probe during operator handling, which could lead to sensor desensitization or detachment from its fixed position over time, this application provides an online inspection device for the installation of adhesive strips on automotive parts.

[0006] The online inspection device for the installation of automotive component rubber strips provided in this application adopts the following technical solution:

[0007] An online inspection device for the installation of adhesive strips on automotive parts includes a fixed base, on which a clamping member is provided for clamping an automotive disc, on which an adhesive strip is movably attached, and on which four clips are movably installed, and on which the fixed base is provided a first distance sensor for detecting the adhesive strip and a second distance sensor for detecting the four clips.

[0008] The fixed base is provided with a first adjustment component for translating the first distance sensor, a second adjustment component for translating the second distance sensor, a lifting component for synchronously raising and lowering the first and second distance sensors, a protective component for protecting the first and second distance sensors, a rotating component for rotating the car disc, and a pressing component for flattening the rubber strip.

[0009] The first adjustment assembly includes a first adjustment frame fixed to the first ranging sensor and an adjustment component for translating the first adjustment frame;

[0010] The second adjustment assembly includes a second adjustment frame fixed to the second ranging sensor and a translation component for translating the second adjustment frame.

[0011] The lifting assembly includes two fixed frames fixed to a fixed base, movable screw blocks respectively movably disposed on the two fixed frames, and a lifting component for synchronously lifting and adjusting the two movable screw blocks;

[0012] The protective assembly includes two second light-blocking plates and a third light-blocking plate that are rotatably mounted on the first distance sensor and the second distance sensor, a first light-blocking plate that is fixed on the first distance sensor and the second distance sensor, and a driving component for synchronously driving the two second light-blocking plates and the third light-blocking plate to rotate.

[0013] The extrusion assembly includes a movable pressure roller and a marker pen movably mounted on a rotating disk, as well as a swinging component for adjusting the swing of the marker pen.

[0014] The rotating assembly includes a rotating disk and an adjusting disk rotatably mounted on a fixed base, as well as a rotating component for synchronously driving the rotating disk and the adjusting disk to rotate.

[0015] The fixed base is also provided with a switching component for switching the driving of the lifting component and the rotating component, and a timing component for periodically turning on the second ranging sensor. The driving component can be automatically driven by the lifting component.

[0016] By adopting the above technical solution, the manually applied adhesive strips and manually assembled clips on automotive parts can be detected using a laser distance sensor. First, the sensor frame is erected to a certain height to allow space for the parts to be placed and removed. Then, the laser distance sensor emits a laser beam towards the measurement point and reflects it. By measuring the total time of the laser's round trip, the distance between the sensor and the adhesive strip and clip can be calculated. Automotive parts are usually irregularly shaped circles, so applying adhesive strips to automotive parts will also result in irregular circles, and installing multiple clips on automotive parts will result in uneven distribution. In order to ensure the effectiveness of the laser distance sensor in detecting automotive parts, the laser distance sensor is usually projected at a designated position to avoid external interference such as vibration and impact when the laser distance sensor is moved, which would affect the accuracy of the laser distance sensor in measuring adhesive strips and multiple clips.

[0017] Using a laser distance sensor fixed at a single point means that it can only measure distances at one point on the adhesive strip, and cannot measure distances at multiple points on the adhesive strip. Consequently, it cannot detect the overall condition of the adhesive strip installed on the automotive parts. If there are stains, damage, or uneven installation on the surface of the adhesive strip, measuring only one point will produce a large error, and thus the accuracy of the detection of the adhesive strip on the automotive parts cannot be guaranteed.

[0018] Using a laser distance sensor fixed at one point means that the laser distance sensor can only measure the distance of one buckle. In order to detect multiple buckles on automotive parts, multiple laser distance sensors are usually needed to measure the distance of multiple buckles. Although this detection method is accurate, it is not only more expensive, requiring multiple sensors, but also requires more space for installation and layout. Furthermore, the maintenance and management of multiple sensors is relatively complex, requiring regular inspection and maintenance.

[0019] When laser distance sensors are used for distance measurement in factories, the transmission of the sensor beam is often affected by dust, particles, and stains on adhesive strips and clips in the projection environment. In addition, strong light in the working environment can also interfere with the normal operation of the sensor, resulting in inaccurate measurement data. This affects the accuracy of laser distance sensors in measuring the distance of manually applied adhesive strips and manually assembled clips on automotive parts.

[0020] When using laser distance sensors, it is usually necessary to precisely control the distance between the laser distance sensor and the object being measured to avoid errors when the laser distance sensor detects adhesive strips and clips. Therefore, the distance between the laser distance sensor and the adhesive strips and clips needs to be adjusted. The larger the size of the adhesive strips and clips on automotive parts, the higher the height of the laser distance sensor also needs to be adjusted to keep the distance between the laser distance sensor and the adhesive strips and clips within the measurement range and reduce the error of the laser distance sensor in detecting adhesive strips and clips.

[0021] The first distance sensor projects a laser beam onto the rubber strip, while the second distance sensor projects a laser beam onto the four clips. Both sensors project a downward-facing laser beam vertically. The laser beam reaches the rubber strip and clips and is reflected vertically upwards, allowing for distance measurement. A rotating assembly allows the car disc, rubber strip, and four clips to rotate, enabling the first distance sensor to perform multi-range distance measurement on the entire circumference of the rubber strip, and the second distance sensor to measure the distance to all four clips. A first adjustment assembly allows for translational adjustment of the first distance sensor, ensuring continuous projection onto the rubber strip during rotation. Similarly, a second adjustment assembly allows for translational adjustment of the second distance sensor, ensuring sequential projection onto the four clips during rotation. The system projects and detects four clips at different positions. The height of the first and second ranging sensors can be adjusted using a lifting assembly to accommodate the size and model of the adhesive strip and clips. This ensures optimal height for detection. A protective assembly protects the first and second ranging sensors from light and dust, preventing light and dust from affecting their ranging accuracy. A pressing assembly flattens the adhesive strip, preventing protrusion errors during measurement. The system also allows for physical testing of the adhesive strip before laser projection detection, ensuring effective ranging.

[0022] Optionally, the lifting component includes two movable screws, two fifth bevel gears, two sixth bevel gears, two support rods, two seventh bevel gears, and an eighth bevel gear, all rotatably mounted on a fixed base. The two movable screws are fixedly connected to the two fifth bevel gears, the two fifth bevel gears mesh with the two sixth bevel gears, the two sixth bevel gears are fixedly connected to the two support rods, the two support rods are fixedly connected to the two seventh bevel gears, and both seventh bevel gears are movably meshed with the eighth bevel gear. The two movable screws are threadedly connected to two movable screw blocks, and each of the two movable screw blocks has a fixed square hole on its inner side. The second adjusting frame and the first adjusting frame are slidably connected to the two fixed square holes.

[0023] By adopting the above technical solution, the lifting component can adjust the height of the first and second distance sensors, and control the height of the first and second distance sensors within the measurement range. The lifting component can drive the eighth bevel gear, two seventh bevel gears, two support rods, two sixth bevel gears, two fifth bevel gears, and two movable screws to rotate counterclockwise, thereby driving the two movable screw blocks to move upward, and driving the first and second adjustment frames and the first and second distance sensors to move upward respectively. The height of the first and second distance sensors can be adjusted according to the model of the rubber strip and buckle.

[0024] Optionally, the adjusting component includes a first outer rod movably disposed on the adjusting plate, a movable circular block fixed on the first outer rod, and an adjusting circular groove disposed on the adjusting plate. The movable circular block slides inside the adjusting circular groove. A first square hole is provided on the inner side of the first outer rod. The first adjusting frame is slidably connected to the first square hole. The shape of the adjusting circular groove is the same as the shape of the rubber strip.

[0025] By adopting the above technical solution, the adjusting component can drive the first distance sensor to move horizontally, so that when the irregular circular rubber strip rotates, the first distance sensor can always project onto the rubber strip for distance measurement. The adjusting component can drive the adjusting disk to rotate. When the adjusting disk rotates, by adjusting the shape of the circular groove, the movable circular block, the first outer rod, the first adjusting frame and the first distance sensor can be moved horizontally in sequence, so that the positions of the first distance sensor and the movable pressure roller can be moved horizontally.

[0026] Optionally, the translation component includes four adjusting blocks fixed on the rotating disk, a wedge block movably disposed on the fixed base, an annular spring fixed on the wedge block, and a second outer rod. The inner side of the second outer rod is provided with a second square hole. The second adjusting bracket is slidably connected to the second square hole. The annular spring is fixedly connected to the fixed base. The four adjusting blocks are respectively located directly below the four buckles, and the four adjusting blocks are movably fitted with the wedge block.

[0027] By adopting the above technical solution, the translation component can drive the second ranging sensor to move, so that when the four buckles on the outside of the rubber strip rotate, the second ranging sensor can sequentially measure the distance of the four buckles. The translation component can drive the rotating disk and the four adjusting blocks to rotate. Since the four adjusting blocks are located directly below the four buckles, when the four adjusting blocks rotate, they will sequentially come into contact with the wedge block. The thrust of the adjusting block during rotation can drive the wedge block to move, causing the ring spring to compress. This can then sequentially drive the second outer rod, the second adjusting frame, and the second ranging sensor to move. When the adjusting block comes into contact with the sensing block, it means that the projection point of the second ranging sensor is aligned with the buckle. Then the sensing block will transmit a signal to the second ranging sensor to open it, and the second ranging sensor can then project and detect the buckle. When the adjusting block separates from the sensing block, the second ranging sensor will turn off to avoid the energy consumption caused by the second ranging sensor being continuously turned on.

[0028] Optionally, the rotating component includes a first bevel gear, two second bevel gears, two connecting rods, two third bevel gears, and two fourth bevel gears rotatably mounted on a fixed base. The two fourth bevel gears are fixedly connected to a rotating disk and an adjusting disk, respectively. The two fourth bevel gears mesh with the two third bevel gears, respectively. The two third bevel gears are fixedly connected to the two connecting rods, respectively. The two connecting rods are fixedly connected to the two second bevel gears, respectively. Both second bevel gears are movably meshed with the first bevel gear.

[0029] By adopting the above technical solution, the rotating component can drive the rotating disk and the adjusting disk to rotate synchronously, thereby enabling the adjusting component and the translation component to drive synchronously. The rotating component can sequentially drive the first bevel gear, two second bevel gears, two connecting rods, two third bevel gears, and two fourth bevel gears to rotate, thereby driving the adjusting disk and the rotating disk to rotate, which in turn drives the car disc, the rubber strip, and the four buckles to rotate, thereby driving the first distance sensor to detect the rubber strip across its entire range, and driving the second distance sensor to detect the four buckles in sequence.

[0030] Optionally, the switching component includes a rotating square rod rotatably mounted on a fixed base, a movable rod and a fixed pull handle, a motor and two movable springs fixed on the fixed base, and limiting arc blocks respectively fixed on the two movable springs. The first bevel gear and the eighth bevel gear are both fixed on the outside of the movable rod. The rotating square rod is fixedly connected to the output shaft of the motor. The outer side of the movable rod is provided with a first annular groove and a second annular groove. The two limiting arc blocks are movably engaged with the first annular groove and the two limiting arc blocks are movably engaged with the second annular groove. The inner side of the movable rod is provided with a rotating square hole, and the rotating square rod is slidably connected to the rotating square hole.

[0031] By adopting the above technical solution, the lifting component and the rotating component can be switched and driven by the switching component, avoiding the driving of the rotating component when the lifting component is driven, and vice versa. This optimizes the driving effect of the lifting component and the rotating component. When the lifting component needs to be driven, the fixed pull handle can be pushed to drive the movable rod, the first bevel gear and the eighth bevel gear upward in sequence, thereby separating the two limiting arc blocks from the first annular groove and aligning the two limiting arc blocks with the second annular groove. The elastic force of the two movable springs can move the two limiting arc blocks into the second annular groove, thereby separating the first bevel gear from the two second bevel gears and meshing the eighth bevel gear with the two seventh bevel gears. When the rotating component needs to be driven, the fixed pull handle can be pulled to drive the movable rod, the first bevel gear and the eighth bevel gear downward in sequence, thereby separating the two limiting arc blocks from the second annular groove and aligning the two limiting arc blocks with the first annular groove. The elastic force of the two movable springs can move the two limiting arc blocks into the first annular groove, thereby separating the eighth bevel gear from the two seventh bevel gears and meshing the first bevel gear with the two second bevel gears.

[0032] Optionally, the driving component includes a first rotating rod, a second rotating rod, a third rotating rod, a first bevel gear, a second bevel gear, a third bevel gear, a fourth bevel gear, and a movable gear, all rotatably mounted on the first and second ranging sensors, and two fixed racks fixed to a fixed base. The second bevel gear and the movable gear are both fixedly connected to the second rotating rod. The first bevel gear and the fourth bevel gear are both fixedly connected to the first rotating rod. The third bevel gear is fixedly connected to the third rotating rod. The movable gear engages movably with the fixed racks. The first bevel gear meshes with the second bevel gear, and the third bevel gear meshes with the fourth bevel gear. Two second light-blocking plates are fixed to the outer sides of the second and third rotating rods, respectively. The third light-blocking plate is fixed to the outer side of the first rotating rod. Both second light-blocking plates are movably fitted with the first light-blocking plate, and both second light-blocking plates are movably fitted with the third light-blocking plate.

[0033] By adopting the above technical solution, the driving component protects the laser lines projected by the first and second ranging sensors when they detect the adhesive strip and buckle. This prevents the laser lines from being affected by strong external light and dust particles, thus ensuring the effective ranging detection of the adhesive strip and buckle. When the lifting component is driven, it can respectively drive the two second light-blocking plates, the third light-blocking plate, the second rotating rod, and the movable gear to move downwards. When the movable gear moves downwards, it meshes with the fixed rack and can rotate. When the movable gear rotates, it sequentially drives the second rotating rod and the second... The rotation of the bevel gear, the first bevel gear, the first rotating rod, the fourth bevel gear, the third bevel gear, and the third rotating rod will respectively drive the two second light-blocking plates and the third light-blocking plate to swing, so that the first light-blocking plate, the two second light-blocking plates, and the third light-blocking plate fit together to form a protective cover. In turn, the first light-blocking plate, the two second light-blocking plates, and the third light-blocking plate on the first distance sensor and the second distance sensor will respectively form two protective covers, protecting the first distance sensor and the second distance sensor and reducing the measurement error of the first distance sensor and the second distance sensor on the rubber strip and the buckle.

[0034] Optionally, the swinging component includes a connecting block movably mounted on a fixed base, a pressure spring and a telescopic spring fixed on the connecting block, a sliding rod fixed on the pressure spring, a movable frame fixed on the telescopic spring, and a marker fixed on the movable frame. The movable frame is hinged to the connecting block, the sliding rod is fixedly connected to the movable pressure roller, the sliding rod is movably attached to the movable frame, the connecting block is fixedly connected to a second light-blocking plate located on the first ranging sensor, and the movable pressure roller and the marker are both movably attached to the adhesive strip.

[0035] By adopting the above technical solution, the driving component and lifting component can indirectly drive the swing component, causing the movable pressure roller to move in contact with the rubber strip. Through the rotation of the rubber strip, the movable pressure roller can flatten the rubber strip and perform physical inspection, facilitating the first distance sensor's re-inspection of the rubber strip and enhancing the inspection effect. When the adjusting component is driven, it can also move the movable pressure roller horizontally, ensuring it remains in contact with the rubber strip for flattening, thus ensuring the rubber strip adheres tightly to the car's chassis. This avoids measurement errors when the first distance sensor projects laser onto the rubber strip. When the movable pressure roller flattens the rubber strip at a specified height, if there are protruding points on the rubber strip, the rotation of the rubber strip can push the movable pressure roller and sliding rod upwards, compressing the injection spring. The sliding rod then pushes the movable frame and marker pen to swing, compressing the telescopic spring. The marker pen can then mark the rubber strip, specifically marking the area next to the protruding points, allowing subsequent workers to quickly locate and address them.

[0036] Optionally, the timing element includes a sensing block fixed on the wedge block, a sensor switch is provided on both the first and second ranging sensors, the four adjusting blocks are movably attached to the sensing block, the sensing block is electrically connected to the sensor switch on the second ranging sensor, a touch block is provided on the movable pressure roller, the touch block is electrically connected to the motor, and the touch block is movably attached to the adhesive strip.

[0037] By adopting the above technical solution, the timing component can drive the second ranging sensor and the motor at regular intervals. When the touch block is in contact with the movable pressure roller, the motor can be driven to stop driving the lifting component. When the sensing block is in contact with the adjusting block, the second ranging sensor can be driven to open and detect the buckle. The second ranging sensor can be opened at regular intervals to avoid the second ranging sensor from consuming energy by being continuously turned on.

[0038] Optionally, the clamping component includes two fixed screw blocks fixed on the rotating disk and two movable screw brackets rotatably mounted on the rotating disk. The two fixed screw blocks are respectively threadedly connected to the two movable screw brackets, and the two movable screw brackets are movably fitted with the car disc. The rotating disk has a storage groove, and the car disc is located inside the storage groove.

[0039] By adopting the above technical solution, the clamping component can clamp and fix the car disc, preventing the car disc from shifting when rotating. The car disc with the assembled rubber strip and four buckles is placed inside the storage slot, and then the car disc can be clamped and fixed by rotating the two movable screws, preventing the car disc from shifting during detection, so as to ensure the effectiveness of the first and second distance sensors in measuring the distance of the rubber strip and four buckles.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. The clamping component can fix the car disc with assembled rubber strips and four buckles on the rotating disc, preventing the car disc from shifting during detection. The switching component can switch the driving of the lifting component and the rotating component, avoiding the rotating component being driven when the lifting component is driven, and vice versa, thus optimizing the driving effect of the lifting component and the rotating component. The lifting component can adjust the height of the first and second ranging sensors. The height of the first and second ranging sensors can be adjusted according to the model and height of the rubber strips and buckles, and the distance between the first and second ranging sensors and the rubber strips and buckles can be controlled, so that the height of the first and second ranging sensors is controlled within the measurement range, thus ensuring the detection effect of the first and second ranging sensors on the rubber strips and buckles.

[0042] 2. When the lifting component is driven, it can indirectly drive the protective component so that the first light-blocking plate, the two second light-blocking plates, and the third light-blocking plate are attached to each other to form a protective cover. Then, the first light-blocking plate, the two second light-blocking plates, and the third light-blocking plate on the first distance sensor and the second distance sensor will form two protective covers respectively, which will protect the first distance sensor and the second distance sensor respectively. This will prevent the first distance sensor and the second distance sensor from being affected by external light and dust particles when projecting laser measurement, thus interfering with the measurement effect of the adhesive strip and the buckle, and reducing the measurement error of the first distance sensor and the second distance sensor on the adhesive strip and the buckle.

[0043] 3. The lifting and protective components allow the movable pressure roller to adhere to the rubber strip. The rotating component drives the adjusting and rotating discs to rotate synchronously, which in turn drives the adjusting and translating components. Simultaneously, it rotates the car disc, rubber strip, and four clips. The adjusting component drives the first ranging sensor and the movable pressure roller to translate. When the first ranging sensor performs laser ranging on the rubber strip, it can consistently project infrared light onto the strip, and the movable pressure roller can always adhere to the strip. Even if the rubber strip is irregularly shaped, the first ranging sensor can perform full-range detection, and the movable pressure roller can perform multi-range physical detection and flattening. When the rubber strip rotates, the first ranging sensor continuously projects infrared light onto the strip for projection detection, and the movable pressure roller continuously adheres to the strip for adhesion detection. Thus, when the rubber strip rotates, the movable pressure roller can press the rubber strip. The pressure roller is used to ensure the rubber strip adheres tightly to the car's chassis, preventing measurement errors when the first distance sensor projects the laser onto the rubber strip. Before the first distance sensor projects the laser onto the rubber strip, the movable pressure roller performs a physical inspection. If there are raised points on the rubber strip, the swinging component can mark them, including the area next to the raised points, to facilitate quick identification and repair by subsequent workers. After the movable pressure roller's physical inspection, the first distance sensor can perform a second laser projection inspection by rotating the rubber strip, allowing for a re-inspection. If the distance measured by the first distance sensor remains unchanged after one rotation, the installation quality is acceptable. Conversely, if the distance measured by the first distance sensor changes, the installation quality is unacceptable, and the thickness of the applied rubber strip is incorrect.

[0044] 4. The translation component can drive the second distance sensor to move horizontally. Combined with the timing component, the second distance sensor can be activated periodically. When the adjusting block and the sensing block are in contact, it indicates that the projection point of the second distance sensor is aligned with the corresponding buckle. The second distance sensor can then project and detect the buckle. Furthermore, by rotating the four adjusting blocks, they sequentially engage with the wedge block and the sensing block, allowing the second distance sensor to project and detect the four buckles sequentially. This ensures the effectiveness of the four buckle projection detections. This method allows for the projection detection of four buckles using only one second distance sensor. It can detect all four buckles on the outer side of the irregular circular rubber strip. If the distances measured by the second distance sensor for the four buckles are consistent after one rotation of the rotating disc, the installation quality of the four buckles is acceptable. Conversely, if the distances measured by the second distance sensor for the four buckles are inconsistent, the installation quality of the four buckles is unacceptable, and the buckle model is incorrect.

The two clamping blocks can be restricted to rotate circumferentially by the two bearings. The rotating disk 14 is provided with a storage groove, and the car disc 19 is located inside the storage groove.

[0067] Both the first ranging sensor 17 and the second ranging sensor 34 are laser distance sensors. Due to the linear propagation and constant speed of light characteristics of lasers, these sensors emit and reflect lasers towards the measurement point during operation. By measuring the total time of the laser's round trip, the distance between the sensor and the measured object can be calculated. The advantages of laser distance sensors are that sufficient distance can be left between the sensor and the product, providing a large operating space, easy handling, and improved work efficiency. Furthermore, laser distance sensors can accurately measure distances, with precision settings down to micrometers. If the thickness of the adhesive strip 20 is incorrect or the model of the assembled buckle 21 is incorrect, causing a change in the sensed distance, this sensor can still detect it, which is incomparable to the precision of contact sensors.

[0068] The implementation principle of the online detection device for automotive component adhesive strip installation in this application embodiment is as follows:

[0069] (1) Place the car disc 19 with the assembled rubber strip 20 and four buckles 21 inside the storage slot, and then clamp and fix the car disc 19 by rotating the two movable screws 57 to prevent the rubber strip 20 and four buckles 21 from shifting during the test, so as to ensure the effectiveness of the first distance sensor 17 and the second distance sensor 34 in measuring the distance of the rubber strip 20 and four buckles 21.

[0070] (2) When it is necessary to adjust the height of the first ranging sensor 17 and the second ranging sensor 34, by pushing the fixed handle 5, the movable rod 4, the first bevel gear 8 and the eighth bevel gear 29 can be moved upward in sequence, so that the two movable springs 6 can be compressed, thereby separating the two limiting arc blocks 7 from the first annular groove, so that the two limiting arc blocks 7 correspond to the second annular groove, and then the elastic force of the two movable springs 6 can move the two limiting arc blocks 7 into the second annular groove, thereby limiting the movable rod 4, thereby separating the first bevel gear 8 from the two second bevel gears 9, and making the eighth bevel gear 29 mesh with the two seventh bevel gears 28. The motor 2 can drive the rotating square rod 3, the movable rod 4, the eighth bevel gear 29, the two seventh bevel gears 28, the two support rods 27 and the two sixth bevel gears 28 in sequence. 6. The two fifth bevel gears 25 and the two movable screws 23 rotate clockwise, which in turn drives the two movable screw blocks 24 to move downwards, which in turn drives the first adjusting frame 16 and the second adjusting frame 33 to move on the first outer rod 15 and the second outer rod 32, respectively. This allows for the adjustment of the height of the first ranging sensor 17 and the second ranging sensor 34. The height of the first ranging sensor 17 and the second ranging sensor 34 can be adjusted according to the model and height of the adhesive strip 20 and the buckle 21. This controls the distance between the first ranging sensor 17 and the second ranging sensor 34 and the adhesive strip 20 and the buckle 21, so that the height of the first ranging sensor 17 and the second ranging sensor 34 is controlled within the measurement range, thereby ensuring the effectiveness of the first ranging sensor 17 and the second ranging sensor 34 in detecting the adhesive strip 20 and the buckle 21.

[0071] (3) When the first ranging sensor 17 and the second ranging sensor 34 move downwards, they can also drive the two second light-blocking plates 38, the third light-blocking plate 39, the second rotating rod 42, and the movable gear 48 to move downwards respectively. When the movable gear 48 moves downwards, it will mesh with the fixed rack 40 and thus rotate. When the movable gear 48 rotates, it will drive the second rotating rod 42, the second bevel gear 45, the first bevel gear 44, the first rotating rod 41, the fourth bevel gear 47, the third bevel gear 46, and the third rotating rod 43 to rotate in sequence. When the second rotating rod 42, the first rotating rod 41, and the third rotating rod 43 rotate, they will drive the two second light-blocking plates 38 and the third light-blocking plate 39 to swing until the movable gear 48 and the fixed rack 40 are separated. When the light is separated, the two second light-blocking plates 38 and the third light-blocking plate 39 will stop swinging, and then the first light-blocking plate 37, the two second light-blocking plates 38 and the third light-blocking plate 39 will stick together to form a protective cover. Thus, the first light-blocking plate 37, the two second light-blocking plates 38 and the third light-blocking plate 39 on the first distance sensor 17 and the second distance sensor 34 will respectively form two protective covers, which will protect the first distance sensor 17 and the second distance sensor 34 respectively, so as to avoid the first distance sensor 17 and the second distance sensor 34 from being affected by external light and dust particles when projecting laser measurement, which would interfere with the measurement effect of the adhesive strip 20 and the buckle 21, and reduce the measurement error of the first distance sensor 17 and the second distance sensor 34 on the adhesive strip 20 and the buckle 21.

[0072] (4) When the first light-blocking plate 37, the two second light-blocking plates 38, and the third light-blocking plate 39 on the first distance sensor 17 form a protective cover, they can also drive the connecting block 49, sliding rod 50, injection spring 51, movable pressure roller 52, movable frame 53, marker pen 54, and telescopic spring 55 to move downward until the movable pressure roller 52 and the touch block 60 are in contact with the adhesive strip 20. The touch block 60 will transmit a signal to the motor 2, causing the motor 2 to stop driving. In this way, the first distance sensor 17 and the second distance sensor 34 can be kept at a specified height to ensure the distance measurement effect of the first distance sensor 17 and the second distance sensor 34 on the adhesive strip 20 and the buckle 21, and avoid the distance between the first distance sensor 17 and the second distance sensor 34 and the adhesive strip 20 and the buckle 21 being too high or too low, which would affect the distance measurement effect.

[0073] (5) When the first distance sensor 17 is needed to measure the distance of the adhesive strip 20 and the second distance sensor 34 is needed to measure the distance of the four buckles 21, pulling the fixed handle 5 can sequentially drive the movable rod 4, the first bevel gear 8 and the eighth bevel gear 29 downward, so that the two movable springs 6 can be compressed, thereby separating the two limiting arc blocks 7 from the second annular groove, so that the two limiting arc blocks 7 correspond to the first annular groove, and then the elastic force of the two movable springs 6 can move the two limiting arc blocks 7 into the first annular groove, thereby limiting the movable rod 4. This position allows the eighth bevel gear 29 to separate from the two seventh bevel gears 28, and the first bevel gear 8 to mesh with the two second bevel gears 9. The motor 2 then sequentially drives the rotating square rod 3, the movable rod 4, the first bevel gear 8, the two second bevel gears 9, the two connecting rods 10, the two third bevel gears 11, and the two fourth bevel gears 12 to rotate. This, in turn, drives the adjusting disc 13 and the rotating disc 14 to rotate. When the rotating disc 14 rotates, it sequentially drives the car disc 19, the rubber strip 20, and the four clips 21 to rotate. When the adjusting disc 13 rotates, it adjusts the shape of the circular groove. When the adjusting disk 13 rotates, it sequentially drives the movable circular block 59, the first outer rod 15, the first adjusting frame 16, the third light-blocking plate 39, the two second light-blocking plates 38, the first light-blocking plate 37, the connecting block 49, the sliding rod 50, the pressure spring 51, the movable pressure roller 52, the touch block 60, the movable frame 53, the marker pen 54, the telescopic spring 55, and the first distance sensor 17 to translate. This allows for the translation of the positions of the first distance sensor 17 and the movable pressure roller 52. Furthermore, through the synchronous rotation of the adjusting disk 13 and the rotating disk 14, as well as the shape of the rubber strip 20 and the adjusting groove, the position of the first distance sensor 17 and the movable pressure roller 52 can be translated. This allows the first ranging sensor 17 to project infrared light onto the adhesive strip 20 continuously when performing laser ranging on the adhesive strip 20, and the movable pressure roller 52 to always adhere to the adhesive strip 20. Even if the adhesive strip 20 is an irregular circle, the first ranging sensor 17 can perform full-range detection, and the movable pressure roller 52 can also perform multi-range physical detection and flattening. When the adhesive strip 20 rotates, the first ranging sensor 17 can project infrared light onto the adhesive strip 20 continuously for projection detection, and the movable pressure roller 52 can always adhere to the adhesive strip 20 for adhesion detection.

[0074] (6) When the rubber strip 20 rotates, the movable pressure roller 52 can flatten the rubber strip 20 so that the rubber strip 20 is close to the car disc 19, avoiding measurement error when the first distance sensor 17 projects laser onto the rubber strip 20. At the same time, before the first distance sensor 17 projects laser onto the rubber strip 20, the movable pressure roller 52 can perform physical detection on the rubber strip 20. When the movable pressure roller 52 flattens the rubber strip 20 at the specified height, if there is a protrusion on the rubber strip 20, the movable pressure roller 52 and the sliding rod 50 can be pushed to move upward when the rubber strip 20 rotates, so that the pressure spring 51 is squeezed. Then the sliding rod 50 can push the movable frame 53 and the marker pen 54 to swing, so that the telescopic spring 55 is squeezed. Then the marker pen 54 can mark the rubber strip 20 and mark the side of the protrusion position of the rubber strip 20 so that the subsequent staff can quickly find the protrusion and process it.

[0075] (7) Simultaneously, after the movable pressure roller 52 performs physical inspection on the rubber strip 20, the first distance sensor 17 can perform laser projection inspection on the rubber strip 20 again by rotating the rubber strip 20. This allows for a re-inspection of the rubber strip 20, enhancing the distance measurement effect. Because when the movable pressure roller 52 inspects the rubber strip 20, there may be pressure bumps on the rubber strip 20 causing measurement errors. If there are no measurement errors when the first distance sensor 17 projects and inspects the rubber strip 20, it indicates that the flatness of the rubber strip 20 is very accurate. If the first distance sensor 17 does not have measurement errors when projecting and inspecting the rubber strip 20, it means that the flatness of the rubber strip 20 is very accurate. When the distance sensor 17 projects and detects the adhesive strip 20, there is still a measurement error. Therefore, the adhesive strip 20 is marked by physical detection. The point of the protrusion of the adhesive strip 20 can be quickly specified in the subsequent steps. When the adhesive strip 20 rotates one revolution, if the distance measured by the first distance sensor 17 on the adhesive strip 20 does not change, it means that the installation quality of the adhesive strip 20 is qualified. Conversely, if the distance measured by the first distance sensor 17 on the adhesive strip 20 changes, it means that the installation quality of the adhesive strip 20 is unqualified and the thickness of the adhesive strip 20 is incorrect.

[0076] (8) Because the four adjusting blocks 18 are located directly below the four buckles 21, the rotation of the rotating disk 14 will also drive the four adjusting blocks 18 to rotate. When the four adjusting blocks 18 rotate, they will successively come into contact with the wedge block 30. The thrust of the adjusting blocks 18 during rotation can drive the wedge block 30 to move, causing the ring spring 31 to be squeezed. This will then sequentially drive the second outer rod 32, the second adjusting frame 33, and the second distance sensor 34 to move. When the adjusting block 18 comes into contact with the sensing block 36, it means that the projection point of the second distance sensor 34 is aligned with the buckle 21. The sensing block 36 will then send a signal to the second distance sensor 34 to open it. The second distance sensor 34 can then project and detect the buckle 21. When the adjusting block 18 separates from the sensing block 36, the second distance sensor 34 will close to prevent the second distance sensor from being activated. The continuous operation of sensor 34 consumes energy. The rotation of the four adjusting blocks 18 causes them to sequentially engage with the wedge block 30 and the sensing block 36, allowing the second ranging sensor 34 to project and detect the four clips 21 in sequence. This ensures the effectiveness of the projection detection of the four clips 21. In this way, one second ranging sensor 34 can detect the projection of four clips 21, allowing detection of all four clips 21 on the outer side of the irregular circular rubber strip 20. If the distances measured by the second ranging sensor 34 to the four clips 21 are consistent after the rotating disk 14 has rotated one revolution, it indicates that the installation quality of the four clips 21 is qualified. Conversely, if the distances measured by the second ranging sensor 34 to the four clips 21 are inconsistent, it indicates that the installation quality of the four clips 21 is unqualified, or the model of the assembled clips 21 is incorrect.

[0077] (9) After the first ranging sensor 17 and the second ranging sensor 34 have completed their detection with the adhesive strip 20 and the buckle 21, the first bevel gear 8 is re-separated from the two second bevel gears 9, and the eighth bevel gear 29 is meshed with the two seventh bevel gears 28. Through the motor 2, the rotating square rod 3, the movable rod 4, the eighth bevel gear 29, the two seventh bevel gears 28, the two support rods 27, the two sixth bevel gears 26, the two fifth bevel gears 25 and the two movable screws 23 are driven to rotate counterclockwise. This drives the two movable screw blocks 24 to move upward, which in turn drives the first adjusting frame 16 and the second adjusting frame 33, the first ranging sensor 17 and the second ranging sensor 34 to move upward. At the same time, when the first ranging sensor 17 and the second ranging sensor 34 move upward, they also drive the two second light blocking plates 38, the third light blocking plate 39, the second rotating rod 42 and the movable gear 48 to move upward. When the movable gear 48 moves upward, it will re-mesh with the fixed rack 40 and then rotate. When the movable gear 48 rotates, it will drive the two fixed racks 40 to rotate in turn. The second rotating rod 42, the second bevel gear 45, the first bevel gear 44, the first rotating rod 41, the fourth bevel gear 47, the third bevel gear 46, and the third rotating rod 43 rotate. When the second rotating rod 42, the first rotating rod 41, and the third rotating rod 43 rotate, they respectively drive the two second light-blocking plates 38 and the third light-blocking plate 39 to swing. Consequently, the two second light-blocking plates 38 and the third light-blocking plate 39 open during their swing, causing the first light-blocking plate 37, the two second light-blocking plates 38, and the third light-blocking plate 39 to move in opposite directions. When the second light-blocking plate 38 swings, the movable pressure roller 52 also separates from the rubber strip 20, thus ensuring the space above the car disc 19 and preventing the car disc 19 from colliding with the first distance sensor 17 and the second distance sensor 34 when it is removed from the rotating plate 14. This minimizes the risk of damage to the first distance sensor 17 and the second distance sensor 34. At the same time, the opening of the two second light-blocking plates 38 and the third light-blocking plate 39 also facilitates the inspection or cleaning of the first distance sensor 17 and the second distance sensor 34.

[0078] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
