Description

Technical Field

[0001] The utility model relates to the field of camera detection, in particular to a camera detection device. Background Technique

[0002] With the rapid spread of vision applications in the industrial production field, vision measurement plays an increasingly important role in automated equipment. However, the current vision system is relatively sensitive to environmental disturbances. Often, a very small change will have a greater impact on the detection results, resulting in the inability to effectively guarantee the consistency of products under the same vision system. Therefore, how to maintain the stability of the detection environment has become a crucial issue. Only by ensuring the consistency of the detection environment can the stability of camera detection be guaranteed, thereby ensuring the consistency of products. Since the assembly trays need to constantly run on the production line in the production environment, whether it is the change of ambient light or the vibration of the conveyor system itself occurs all the time, making it difficult to form a stable detection environment. Therefore, we focus on building a stable detection environment for cameras on the production line to ensure that the detection environment is less affected by external interference as much as possible, so as to improve the detection accuracy;

[0003] When the existing camera detection device is in use, when the tray is lifted to perform pre-blocking and stopping, it is easy to collide with the tray workpiece, which is not convenient to provide buffering, not convenient to adjust the height of the lifting limit, and the external ambient light during detection is easy to cause interference, and it is not convenient to shield and protect the inside.

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-3 shown, a camera detection device includes a support 1. Two groups of conveyor belts 2 are installed on both sides inside the support 1. Two groups of lifting cylinders 3 are installed inside the support 1. Positioning seats 4 are installed on the tops of the two groups of lifting cylinders 3. A limiting component 5 is installed on the outside of the support 1. The limiting component 5 includes three fixed seats 7. The three fixed seats 7 are respectively fixedly installed on both sides of the support 1. Lifting rods 8 are movably installed inside the three fixed seats 7. A first spring 9 is sleeved on the periphery of the lifting rods 8. A limiting disc 10 is installed at the bottom of the lifting rods 8. Two wing plates 11 are fixedly installed on the periphery of the lifting rods 8 near the top. A screw 12 is connected and installed through the inside of the lifting rods 8. A first fastener 13 and a second fastener 14 are respectively sleeved on the periphery of the screw 12. A third fastener 15 is fixedly installed at the top of the screw 12. A limiting block 16 is sleeved on the periphery of the screw 12 near the top and between the third fastener 15 and the second fastener 14.

[0022] In this embodiment, the three fixed seats 7 are located on the outside of the support 1 and correspond to one group of lifting cylinders 3. The lifting rods 8 are arranged in a guiding and sliding manner inside the fixed seats 7 through the wing plates 11. The lifting cylinder 3 drives the positioning seat 4 to lift, so that the positioning seat 4 is clamped and lifted with the bottom of the tray to be detected, and the tray is pre-blocked and blocked for detection.

[0023] In this embodiment, the diameter of the limit disk 10 is larger than the cross-sectional diameter of the lifting rod 8. The first fastener 13 and the second fastener 14 are sleeved around the screw rod 12 and are arranged in a threaded connection. The lifting rod 8 is guided and slid by the wing plate 11 to prevent rotation, and is buffered when the tray is lifted under the action of the first spring 9.

[0024] In this embodiment, the third fastener 15 and the screw rod 12 are fixedly connected to each other. The limit block 16 is sleeved around the screw rod 12 and is arranged in a movable connection. The lifted tray is limited by the limit block 16, and the height of the limit is adjusted by the screw rod 12.

[0025] In this embodiment, a protection component 6 is installed at one end near the top of the support 1. The protection component 6 includes a dark box 17. The dark box 17 is fixedly installed above the support 1 through a bracket. A lifting cover 18 is movably installed at the bottom end of the outside of the dark box 17. A rubber pad 19 is installed at the bottom of the lifting cover 18. A fixing ring 20 is fixedly installed at a position near the middle of the periphery of the dark box 17. Two guide rods 21 are installed on each of the four sides of the top of the lifting cover 18 and penetrate through and are installed inside the fixing ring 20. A second spring 22 is sleeved around the guide rod 21. The tray is transported to directly below the dark box 17 for lifting detection, so that the tray can easily contact the rubber pad 19 in advance to make the lifting cover 18 slide, and the tray is buffered and the height is matched through the sliding of the lifting cover 18.

[0026] In this embodiment, a detection camera and a camera light source module are installed inside the dark box 17. The lifting cover 18 is arranged to slide up and down outside the dark box 17. The tray is detected by the detection camera and the camera light source module inside the dark box 17, so that the dark box 17 and the lifting cover 18 shield the external ambient light.

[0027] In this embodiment, the bottom end of the guide rod 21 and the lifting cover 18 are fixedly installed. The guide rod 21 penetrates through the inside of the fixing ring 20 and is arranged to slide. The lifting cover 18 is supported by the sliding of the guide rod 21, so that the height of the lifting cover 18 matches the height of the lifted tray, and the lifting cover 18 is attached and sealed to the lifted tray through the rubber pad 19.

[0028] It should be noted that the present utility model is a camera detection device. When in use, two conveyor belts 2 are started, and the workpiece on the tray to be detected is sequentially placed on the two conveyor belts 2 for conveying. When the tray is conveyed directly below the dark box 17 and the next tray is pre-blocked and stopped, the visual detection is used to control the lifting cylinder 3 to make the positioning seat 4 rise and engage with the bottom of the tray, lifting the tray. The top of the tray contacts the three limit blocks 16, enabling the lifting rod 8 to slide adaptively. Under the action of the first spring 9, the lifted tray is buffered and limited, causing the tray to disengage from the conveyor belt 2 for pre-blocking and stopping. When the height of the limit needs to be adjusted, the first fastener 13 is rotated to disengage from the lifting rod 8, and the third fastener 15 is rotated to make the screw rod 12 rotate and slide up and down under the action of the thread. After adjusting to the specified height, the screw rod 12 is fixed by the contact of the first fastener 13 with the lifting rod 8, and the position of the limit block 16 is adjusted and tightly fixed by the second fastener 14. When detecting, the lifting cylinder 3 corresponding to the lower part of the dark box 17 lifts the tray, making the top edge of the tray contact the rubber pad 19 of the lifting cover 18, and driving the lifting cover 18 to slide adaptively. Under the action of the second spring 22, the rubber pad 19 is fitted and fixed with the tray. The tray is located inside the dark box 17, and the external ambient light is shielded by the dark box 17 and the lifting cover 18. The tray workpiece is detected by the detection camera and the light source module inside the dark box 17.
