Description

Technical Field

[0001] The present invention relates to the field of automobile production, and in particular to an automobile door detection device. Background Art

[0002] At present, the automobile manufacturing industry is facing an increasing demand for production efficiency and consumers' higher expectations for automobile quality. However, traditional automobile door inspection methods and equipment have gradually become a bottleneck restricting the efficient production of the automobile manufacturing industry due to their limitations such as cumbersome inspection processes, low automation, and low inspection efficiency. This situation not only affects the production speed of automobiles, but may also lead to potential quality problems due to insufficient inspection, thus affecting the overall performance and driving safety of the automobile, and posing a challenge to the market competitiveness and brand reputation of automobile manufacturers.

[0003] Traditional car door inspection often relies on manual operation, which is not only time-consuming and labor-intensive, but also easily affected by the subjective judgment of the operator, resulting in inconsistent inspection results and potential false detection or missed detection. In addition, due to the low degree of automation and intelligence of the inspection equipment, each door often needs to be inspected separately, and it is impossible to synchronize the inspection operation with the loading and unloading operation, which not only limits the improvement of inspection efficiency, but also increases production costs, affecting the economic benefits of automobile manufacturers.

[0004] Therefore, improving the efficiency of automobile door detection has become a key issue that needs to be urgently addressed in the automobile manufacturing industry. Summary of the invention

[0005] In view of this, the present invention provides an automobile door inspection device. The device, through its innovative turntable assembly design, and upper and lower inspection modules, not only realizes the synchronization of loading and unloading operations and inspection operations, but also can simultaneously inspect the AB surfaces of the automobile door in both directions, greatly improving the inspection efficiency and production effectiveness.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] An automobile door detection device, comprising a machine platform, a turntable assembly, an upper detection module located above the turntable assembly, and a lower detection module located below the turntable assembly. The turntable assembly includes a driving unit, a turntable driven by the driving unit to rotate, and two rotating jigs arranged on the turntable and used for loading automobile doors. The rotating jig is rotatably connected to the turntable through a crossed roller bearing. A jig hollow is dug in the middle of the rotating jig, a bearing hollow is dug in the middle of the crossed roller bearing, and a turntable hollow is dug in the turntable. The upper detection module detects the automobile door on the rotating jig from top to bottom, and the lower detection module sequentially passes through the turntable hollow, the bearing hollow, and the jig hollow from bottom to top and then detects the automobile door on the rotating jig.

[0008] Through its innovative turntable assembly design, as well as the upper detection module and the lower detection module, this device not only realizes the synchronous progress of the loading / unloading operation and the detection operation, but also can detect the A and B sides of the automobile door simultaneously in both directions, greatly improving the detection efficiency and production efficiency, and injecting strong impetus into the intelligent upgrade of the automobile manufacturing industry.

[0009] As the "heart" of this device, the core highlight of the turntable assembly design lies in the use of two rotating jigs to load two automobile doors. This design breaks through the limitations of the traditional single loading mode, enabling the loading / unloading operation and the detection operation to proceed in parallel without conflict, and significantly shortening the operation cycle. The rotating jig is precisely connected to the turntable through a crossed roller bearing, which not only ensures the stability and precise positioning of the automobile door during the detection process, but also provides a direct channel for the penetration detection of the lower detection module through the ingenious design of the jig hollow and the bearing hollow, realizing the seamless connection of the detection process.

[0010] The upper detection module directly detects the automobile door on the rotating jig from top to bottom, while the lower detection module conducts a penetration detection of the A and B sides of the automobile door from bottom to top through the ingenious layout of the turntable hollow, the bearing hollow, and the jig hollow. This design not only realizes the comprehensive detection of the A and B sides of the automobile door, ensuring the comprehensiveness and accuracy of the detection results, but also effectively avoids detection dead angles through two-way detection, improving the detection efficiency and the accuracy of quality control.

[0011] In summary, the innovative automobile door detection device, through its unique turntable assembly design and all-round cooperation of the detection modules, not only significantly improves the efficiency and quality of automobile door detection, but also demonstrates the outstanding achievements of modern manufacturing in the pursuit of high efficiency, high precision, and intelligent production.

[0028] Preferably, the lower detection module includes an A-side photography detection device, and the A-side photography detection device is located in a darkroom.

[0029] The A-side photography detection device of the lower detection module, through its design located in a darkroom, not only avoids interference from external light on the detection results but also realizes precise detection of the A-side of the car door through high-precision image acquisition and analysis technologies. The darkroom environment not only provides stable detection conditions but also ensures the accuracy and reliability of the detection results by reducing the influence of environmental factors on the detection accuracy. This design not only significantly improves the detection efficiency and quality of the A-side of the car door but also ensures the flawlessness of the car door surface through precise image analysis, enhancing the overall quality and driving experience of the car.

[0030] Preferably, the outer periphery of the upper detection module is wrapped with a machine cover, the machine cover is provided with a door, and the door is provided with a safety grating.

[0031] The hood wrapped around the outer periphery of the upper detection module not only provides physical protection for the detection equipment, avoiding interference and damage to the equipment from external factors, but also optimizes the detection environment through the design of the hood, ensuring the efficiency and stability of the detection process. The door and safety grating set on the hood further enhance the safety performance of the equipment. The design of the door not only facilitates the operation and debugging of the equipment by the operator, but also realizes the safety protection of the operator through the intelligent monitoring of the safety grating. Once the safety grating detects that the door is opened or a foreign object enters, the equipment will immediately stop running, effectively avoiding the occurrence of safety accidents and ensuring the safety of the operator. This design not only reflects the high attention of modern manufacturing to production safety, but also improves the operation safety and production efficiency of the equipment through an intelligent safety protection mechanism.

[0053] The sequential arrangement of the four outer frames of the jig fixing frame 232, namely the first outer frame 511, the second outer frame 512, the third outer frame 513, and the fourth outer frame 514, not only constitutes the main supporting structure of the car door, but also realizes the stable support and precise positioning of the car door edge through the setting of the support extension plane 515.

This design not only improves the stability of the car door during the detection process, but also realizes the full - range support and positioning of the car door through the optimized layout of the outer frame and the connecting corner 516, ensuring the consistency and reliability of the detection results. The design of the corner support surface 517 of the connecting corner 516 further enhances the support and protection of the four corners of the car door, ensuring the overall stability and safety of the car door during the detection process and effectively avoiding detection errors caused by insufficient support.

This design can not only quickly adjust the position and angle of the fixture fixed frame 232 according to the size and shape of the car door to ensure the stable and accurate positioning of the car door during the detection process, but also improve the adaptability of the equipment to car doors of different models through the flexibility of sliding, meeting the diverse production needs in the automotive manufacturing industry.

The precise control of the clamping cylinder 541 ensures the smoothness and controllability of the clamping process; the design of the inclined concave arc of the deep groove ball bearing 542 and the clamping block 543 not only realizes the rapid and stable clamping of the rotary jig 230, but also reduces the frictional force during the clamping process through the rolling effect of the deep groove ball bearing 542, improving the efficiency and safety of clamping. This design not only ensures the stability and safety of the car door during the detection process, but also realizes the automation and intelligence of the car door detection process through the intelligent clamping mechanism, significantly improving the detection efficiency and the safety of operation.

[0062] In this embodiment, a sensor 544 is provided beside the clamping assembly 540.

[0063] The setting of the sensor 544 can not only monitor the state of the rotary jig 230 in real time, but also ensure the reliability of the position of the rotary jig 230.

The B-side panoramic photographing detection device not only realizes the panoramic photographing of the B side of the car door, but also accurately detects the defects and flaws on the door surface through image analysis technology, ensuring the appearance quality of the car door.

[0066] In this embodiment, the upper detection module 300 further includes a PIN - pin detection device and an Emergency release cover presence / absence detection device for detecting the car door loaded in the other of the two rotary jigs 230.

[0067] The PIN - pin detection device and the Emergency release cover presence / absence detection device respectively perform intelligent detection on the PIN pins and the emergency release cover in the car door. The PIN - pin detection device ensures the position, size, and installation quality of the PIN pins through high - precision image recognition and measurement technology, effectively avoiding connection failures caused by PIN - pin problems. The Emergency release cover presence / absence detection device ensures the correct installation of the emergency release cover through intelligent sensing technology, improving the safety performance of the car in emergency situations. These intelligent detection devices not only significantly improve the efficiency and accuracy of detection, but also provide important references for the quality control and production optimization of car doors through data collection and analysis.

[0068] In this embodiment, the lower detection module 400 includes an A - side photographing detection device, and the A - side photographing detection device is located in a dark room.

[0069] The A - side photographing detection device of the lower detection module 400, through the design of being located in a dark room, not only avoids the interference of external light on the detection results, but also realizes the precise detection of the A - side of the car door through high - precision image acquisition and analysis technology. The dark - room environment not only provides stable detection conditions, but also ensures the accuracy and reliability of the detection results by reducing the influence of environmental factors on the detection accuracy. This design not only significantly improves the detection efficiency and quality of the A - side of the car door, but also ensures the flawlessness of the car - door surface through precise image analysis, improving the overall quality and driving experience of the car.

[0070] The two rotary jigs respectively correspond to the first position and the second position. The two rotary jigs can switch positions between the first position and the second position. They work together to ensure that every detail of the car door can be strictly and comprehensively detected to meet excellent quality standards. This detection process not only reflects the high efficiency of automation technology, but also incorporates attention to details and precise grasp of technology, setting a new benchmark for the automotive manufacturing industry.

[0071] At the first position, the door is powered on and the bottom of the A - side is detected. When the door is placed here, the four high - precision cameras at the bottom immediately start to take pictures of the A - side of the door. This process ensures that the manufacturing quality and design details at the bottom of the door are accurately presented, providing key data support for subsequent detection links.

[0072] The second position is equipped with more complex detection equipment, including omnidirectional photographing of the AB parts of the car door, detection of the lighting effect of the ambient light by a colorimeter, and multi-angle observation by a total of ten cameras, ten on the upper and lower sides. Among them, the use of the colorimeter is the technical key point. It can accurately detect the color consistency and brightness of the ambient light, ensuring the perfect presentation of the lighting effect inside the car door. This series of detections not only cover the appearance and functionality of the car door, but also comprehensively evaluate the aesthetics and comfort of the car door.

[0073] After the comprehensive detection at the second position, the car door returns to the first position again. At this time, manual operation intervenes to unplug the plug-in wire used for power supply. Next, a total of six or five prism cameras on the left and right, and a presence / absence camera dedicated to solder joint detection (a total of seven cameras) work together. The prism cameras are responsible for detecting whether the pin is skewed, while the solder joint detection camera ensures that the solder joints that may be blocked by the plug-in wire during the test at the second position are detected again, so as to achieve no omission and no dead angle in the detection, ensuring that every detail of the car door meets the high-standard manufacturing requirements.

[0074] Finally, when all the detection processes are completed, manual blanking is carried out. Before blanking, the printer prints out the automatically generated detailed detection report, and the operator pastes it on the car door. This report is not only an intuitive display of the car door detection results, but also an authoritative proof of the car door manufacturing quality. The perfect combination of this series of automated detections and manual operations not only demonstrates the high efficiency and precision of modern automobile manufacturing, but also reflects the ultimate pursuit of product quality and user safety.

[0075] In summary, through the position switching between the first position and the second position by two rotary fixtures, and the ingenious combination of automated detection and manual operation, the detection process of the car door not only achieves full coverage from appearance to function, from details to the whole, but also ensures that every link in the manufacturing process of each car door can reach excellent quality standards, setting a new example for the automobile manufacturing industry.

[0076] In this embodiment, the outer periphery of the upper detection module 300 is wrapped with a hood, and the hood is provided with a door opening, and the door opening is provided with a safety grating.

[0077] The hood surrounding the upper detection module 300 not only provides physical protection for the detection equipment, avoiding interference and damage to the equipment from external factors, but also optimizes the detection environment through the design of the hood, ensuring the efficiency and stability of the detection process. The door and safety grating set on the hood further enhance the safety performance of the equipment. The design of the door not only facilitates the operation and debugging of the equipment by the operator, but also realizes the safety protection of the operator through the intelligent monitoring of the safety grating. Once the safety grating detects that the door is opened or foreign objects enter, the equipment will immediately stop running, effectively avoiding the occurrence of safety accidents and ensuring the safety of the operator. This design not only reflects the high attention of modern manufacturing to production safety, but also improves the operation safety and production efficiency of the equipment through an intelligent safety protection mechanism.
