Description

Technical Field

[0001] This utility model relates to the field of automated inspection technology, specifically to an inspection device for processing automotive parts based on machine vision. Background Technology

[0002] In today's booming automotive industry, automobile manufacturing processes are becoming increasingly sophisticated and complex. As fundamental components of a vehicle, the quality of automotive parts directly determines the overall vehicle's performance, safety, and reliability. Therefore, the post-processing inspection of automotive parts is crucial in the entire automotive production process, serving as a key checkpoint for controlling product quality.

[0003] Automakers need to improve production efficiency while ensuring high consistency and precision in the quality of auto parts. Large-scale production requires fast and efficient testing methods to match the production line pace and prevent the testing process from becoming a bottleneck. However, traditional testing methods are insufficient to achieve comprehensive and accurate testing of high-precision and complex auto parts. Therefore, there is an urgent need for a new testing technology with a high degree of automation and high testing accuracy to ensure that the quality of auto parts meets high standards.

[0004] Traditional inspection devices use motors and conveyor belts to transport and inspect workpieces. However, when the motor drives the conveyor, vibrations can occur, causing the workpieces to suddenly shake and tilt, which affects the inspection effect and reduces the practicality of the device.

[0038] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0039] like Figures 1 to 7 As shown, an embodiment of this utility model provides a machine vision-based inspection device for processing automotive parts, comprising: a base 1; a support plate 2 fixedly connected to one side of the base 1, a motor 3 fixedly installed at the top of the support plate 2, a cleaning device 4 provided at the top of the base 1 for cleaning dust on the parts, support frames B5 fixedly connected to both sides of the top of the base 1, and light-blocking curtains 7 respectively provided on both sides of the support frame B5, a conveying device 6 provided in the middle of the base 1 for conveying parts, a ring light 8 fixedly installed at the top of the inside of the support frame B5, a detector A9 fixedly installed in the middle of the ring light 8 and the top of the inside of the support frame B5 for detecting the top of the parts, and detectors B10 fixedly installed on opposite sides of the inside of the support frame B5 for detecting both sides of the parts. The two light-blocking curtains 7 are fixedly installed on both sides of the support frame B5 so that when the ring light 8 is activated, it can illuminate the parts more evenly.

[0040] like Figures 4 to 6 As shown, the conveying device 6 includes a rotating shaft A61 fixedly installed at the output end of the motor 3. A rotating shaft B62 is symmetrically arranged on one side of the rotating shaft A61. Multiple gears 63 are fixedly connected to the outer arc surfaces of the rotating shaft A61 and the rotating shaft B62, and gear racks 64 are meshed on the outer arc surfaces of the gears 63.

[0041] like Figures 4 to 6As shown, several fixed shells 65 are fixedly connected to the outer surfaces of multiple gear racks 64. A guide rod 66 is connected through the inside of the fixed shell 65, and clamping plates 68 are slidably connected to the arc surfaces at both ends of the guide rod 66. A baffle 69 is provided in the middle of the fixed shell 65. Springs 67 are fixedly connected to the rear of the two clamping plates 68. The tension of the two springs 67 can push the two clamping plates 68 to move towards each other, thereby clamping and fixing the parts.

[0042] In this embodiment of the utility model (working principle), during use, the starter motor 3 drives the rotating shaft A61 to rotate, and the gear 63 drives the gear rack 64 to move, which in turn drives the fixed shell 65 to move. Then, the part is placed in the middle of the two clamping plates 68. Under the action of the spring 67, the clamping plates 68 can be pushed to clamp the part and reverse the movement. The motor 3 rotates and drives the workpiece to move forward. The cleaning device 4 cleans the dust on the workpiece to avoid affecting the detection effect of the detection device. Then, it enters the interior of the support frame B5 through the light-blocking curtain 7. Under the action of the light-blocking curtain 7, the ring light 8 can illuminate the workpiece more evenly, and prevent external light sources from entering the interior of the support frame B5 and affecting the detection of the workpiece by the detectors B10 and A9. Then, the detector A9 detects the top of the part, while the two detectors B10 detect the two sides of the workpiece. The results are then sent to the external display for display.

[0043] like Figures 4 to 7 As shown, the cleaning device 4 includes a support frame A41 fixedly connected to both sides of the top of the base 1. Dustproof nets B42 are fixedly installed on both sides and the outer side of the top of the support frame A41, and a blower 43 is respectively provided on one side of the multiple dustproof nets B42. The dustproof nets B42 are placed on one side of the blower 43. When the blower 43 is started, air is drawn in through the dustproof nets B42. At this time, the dustproof nets B42 block the dust and prevent the dust from entering the interior of the blower 43.

[0044] like Figure 7 As shown, several exhaust pipes 44 are fixedly installed at the output ends of multiple blowers 43, and one side of the exhaust pipe 44 is flush with the inner surface of the support frame A41. The exhaust pipes 44 are fixedly installed at the output ends of the blowers 43. When the blowers 43 are started, the airflow can be blown onto the workpiece through the exhaust pipes 44 to clean the dust and make the airflow more concentrated.

[0045] In this embodiment of the utility model, when the motor 3 drives the conveying device 6 to convey the workpiece and reverse it into the interior of the support frame A41, the dust around the workpiece can be cleaned by the combined use of multiple blowers 43 and exhaust pipes 44. At the same time, the dustproof net B42 can prevent the blowers 43 from sucking external dust into the interior of the blowers 43, thus preventing damage to the device.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
