Description

Technical Field

[0001] This utility model relates to the technical field of visual inspection devices for automobile crossbeams, and more particularly to a visual inspection device for automobile crossbeams. Background Technology

[0002] With the rapid development of the automotive industry, the quality requirements for vehicle components are increasingly stringent. As a key load-bearing component in the automotive chassis structure, the automotive crossbeam not only plays a connecting and supporting role but also directly affects the safety performance and driving stability of the entire vehicle. Therefore, efficient and accurate inspection of its appearance quality, dimensional accuracy, and surface defects (such as cracks, scratches, deformation, and poor welding) is particularly important. Manual visual inspection is the most traditional inspection method, mainly relying on workers to observe and judge the presence of defects with the naked eye or a magnifying glass. Although it is simple to operate and inexpensive, the inspection results are greatly affected by human experience, subjective judgment, and fatigue, making it prone to false positives and false negatives. It has poor ability to identify minute defects, making it difficult to meet the requirements of high-precision quality control, and its low inspection efficiency makes it unsuitable for mass production line applications.

[0003] Therefore, a visual inspection device for automotive crossbeams needs to be designed to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of easy false detection and low efficiency, this utility model provides a visual inspection device for automobile crossbeams.

[0005] The technical solution of this utility model is as follows: a visual inspection device for automobile crossbeams, comprising a base, a conveyor belt, a support frame, sliding blocks, a first electric push rod, a push plate, a controller, and an infrared detector. The conveyor belt is installed on the top of the base, and the support frame is fixedly connected to the left side of the base. Sliding blocks are slidably connected to both the front and rear sides of the support frame. The first electric push rod is fixedly connected to the two sliding blocks away from the center end. The output shaft of the first electric push rod on the same side passes through the sliding block on the same side and is rotatably connected to a gear. The push plate is fixedly connected to the two gears near the center end. The controller is fixedly connected to the left front side of the base, and the infrared detector is fixedly connected to the upper inner side of the support frame. The controller is electrically connected to the conveyor belt, the first electric push rod, and the infrared detector.

[0006] In addition, it is particularly preferred that the device also includes a buffer plate and springs, with the buffer plate slidably connected to both push plates near the center end, and four springs provided between the buffer plate and the push plate on the same side.

[0007] Furthermore, it is particularly preferred that the support frame also includes a rack, with racks fixedly connected to the inner sides of both the front and rear parts.

[0008] Furthermore, it is particularly preferred that the device also includes a second electric push rod, a push frame, a rotating frame, and a connecting frame. The second electric push rod is fixedly connected to the top of the support frame, the push frame is fixedly connected to the output shaft on the right side of the second electric push rod, the rotating frames are rotatably connected to both the front and rear sides of the push frame, the connecting frames are fixedly connected to the bottom of both rotating frames, and the controller is electrically connected to the second electric push rod.

[0009] Furthermore, it is particularly preferred that the slide block also includes a movable frame, with each movable frame fixedly connected to the sliding block away from the center end. The movable frame is fixedly connected to the middle of the first electric push rod, and the movable frame is slidably connected to the connecting frame.

[0010] Furthermore, it is particularly preferred that the device also includes a support base, jet nozzles, and connecting pipes. Support bases are fixedly connected to both the front and rear sides of the right side of the base. Three jet nozzles are fixedly connected to the top of each of the two support bases near the center. Each of the six jet nozzles passes through the corresponding support base and is fixedly connected to a connecting pipe. The controller is electrically connected to the jet nozzles.

[0011] The beneficial effects are: 1. This utility model uses a second electric push rod to drive a gear and rack linkage mechanism, and then uses an infrared detector to detect the crossbeam, achieving 360-degree all-round detection, avoiding human operation errors, and significantly improving detection efficiency and repeatability.

[0012] 2. This utility model uses a sliding block that slides on a support frame, combined with a first electric push rod and a buffer plate spring structure, to adapt to automotive crossbeams of different widths. It can complete the testing of various models of products without changing the fixtures, thus expanding the applicability of the equipment.

[0013] 3. This utility model automatically cleans the surface of the crossbeam by controlling the jet nozzle before detection, removing dust, oil and other impurities, effectively improving the accuracy of visual recognition and avoiding misjudgment or missed detection due to surface contamination.

Detailed Implementation

[0019] Example: A visual inspection device for automobile crossbeams, such as Figure 1 , Figure 2 and Figure 3 As shown, the system includes a base 1, a conveyor belt 2, a support frame 3, a sliding block 4, a first electric push rod 5, a push plate 6, a controller 19, and an infrared detector 20. The conveyor belt 2 is mounted on the top of the base 1. The support frame 3 is fixedly connected to the left side of the base 1 by bolts. Sliding blocks 4 are slidably connected to both the front and rear sides of the support frame 3. The first electric push rod 5 is fixedly connected to the two sliding blocks 4 away from the center by bolts. The output shaft of the first electric push rod 5 on the same side passes through the sliding block 4 on the same side and is rotatably connected to a gear 9. The push plate 6 is fixed to the two gears 9 near the center. The controller 19 is fixedly connected to the left front side of the base 1 by bolts. The infrared detector 20 is fixedly connected to the upper inner side of the support frame 3 by bolts. The controller 19 is electrically connected to the conveyor belt 2, the first electric push rod 5, and the infrared detector 20.

[0020] like Figure 2 As shown, it also includes a buffer plate 7 and springs 8. The two push plates 6 are slidably connected to the buffer plate 7 near the center end, and four springs 8 are provided between the buffer plate 7 and the push plate 6 on the same side.

[0021] like Figure 1 As shown, it also includes a rack 10. The rack 10 is fixedly connected to the inner sides of both the front and rear parts of the support frame 3. When the gear 9 rotates upward, it meshes with the rack 10.

[0022] like Figure 1 and Figure 3 As shown, it also includes a second electric push rod 11, a push frame 12, a rotating frame 13, and a connecting frame 14. The second electric push rod 11 is fixedly connected to the top of the support frame 3 by bolts. The push frame 12 is fixedly connected to the output shaft on the right side of the second electric push rod 11. The rotating frame 13 is rotatably connected to both the front and rear sides of the push frame 12. The connecting frame 14 is fixedly connected to the bottom of both rotating frames 13. The controller 19 is electrically connected to the second electric push rod 11.

[0023] like Figure 3As shown, it also includes a movable frame 15. The movable frame 15 is fixedly connected to the sliding block 4 at the end away from the center. The movable frame 15 is fixedly connected to the middle of the first electric push rod 5, and the movable frame 15 is slidably connected to the connecting frame 14.

[0024] like Figure 1 and Figure 4 As shown, it also includes a support base 16, a jet nozzle 17, and a connecting pipe 18. The support base 1 is fixedly connected to the front and rear sides of the right side by bolts. Three jet nozzles 17 are fixedly connected to the top of the two support bases 16 near the center end. The six jet nozzles 17 are fixedly connected to the connecting pipes 18 through the corresponding support bases 16. The controller 19 is electrically connected to the jet nozzles 17.

[0025] When this device is used to perform visual inspection of a car crossbeam, the operator first places the crossbeam to be inspected on the conveyor belt 2. The controller 19 starts the conveyor belt 2 and the infrared detector 20, which automatically transports the crossbeam to the inspection area. During this process, the crossbeam passes between two support seats 16. The controller 19 controls the air nozzle 17 to spray compressed air through the connecting pipe 18 to remove dust or oil from the surface of the crossbeam. The controller 19 then shuts off the air nozzle 17. After the infrared detector 20 senses that the crossbeam has reached the designated position, it sends a signal to the controller 19 to pause the conveyor belt 2. The controller 19 then starts the first electric push rod 5, which moves the sliding blocks 4 and gear 9 on both sides towards the center end. This causes the push plate 6 and buffer plate 7 to clamp the crossbeam. The spring 8 provides cushioning protection to prevent excessive clamping that could deform or damage the crossbeam. Then, the controller 19 starts the second electric push rod... The push rod 11 pushes the push frame 12 to the right. The rotating frame 13 drives the push frame 12 connecting frame 14 and the movable frame 15 to rise synchronously. The movable frame 15 drives the sliding block 4 to rise along the guide rail of the support frame 3. The gear 9 meshes with the rack 10, and the rack 10 drives the gear 9 to rotate. The infrared detector 20 detects the crossbeam, achieving 360-degree all-round detection. After the detection is completed, the controller 19 controls the second electric push rod 11 to run in reverse, driving the push frame 12 and the rotating frame 13 to reset, so that the movable frame 15 resets downward. Then, the controller controls the first electric push rod 5 to run in reverse, driving the push plate 6 and the buffer plate 7 to return to their original positions, no longer clamping the crossbeam. The crossbeam that has completed the detection is sent out of the detection area by the start of the conveyor belt 2 through the controller 19. Then, the conveyor belt 2 and the infrared detector 20 are turned off, and it enters the next process or manual sampling inspection. If visual inspection of the car crossbeam is still required, the above operations can be performed again.
