Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic cover detection devices, in particular to an aluminum-plastic cover top surface mirror light detection device. Background Art

[0002] During the inspection of finished aluminum-plastic covers, cameras are required to take photos of the six directions of the aluminum-plastic covers. When taking photos, exposure lights are used to illuminate the area to increase brightness and eliminate shadows. The finished aluminum-plastic covers are transported by belt conveyors. After the facade and side wall photos are taken, the aluminum-plastic covers will pass through a flipping mechanism clamped by two belts (the flipping mechanism can refer to Chinese patent CN202220716851.6) as the belt conveyor is transported to flip the aluminum-plastic covers, so that the bottom surface of the aluminum-plastic covers is converted to the top surface, and then the cameras are used for photo inspection.

[0003] The current aluminum-plastic cover top surface photography device uses a vertically arranged camera with an exposure lamp, and its overall height reaches 25 cm. Together with the camera's connection line, the aluminum-plastic cover flipping mechanism needs to have a height of 30 cm, resulting in a large height of the entire aluminum-plastic cover optical inspection equipment, poor integration, a long transport belt group, and high cost. Summary of the invention

[0004] The technical problem to be solved by the utility model is that the top surface optical detection device after the aluminum-plastic cover is turned over occupies a large space, resulting in a large height of the entire aluminum-plastic cover optical detection device, poor integration, a long transport belt group and high cost.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a mirror light detection device for the top surface of an aluminum-plastic cover, comprising an exposure lamp fixed on a conveyor belt of the aluminum-plastic cover, a light guide cover fixed on the top of the exposure lamp and a camera fixed on one side of the light guide cover, the exposure lamp is a ring-shaped exposure lamp, the interior of the light guide cover is hollow and forms an L-shaped internal light channel, a reflective lens is obliquely fixedly installed at the corner inside the light guide cover, the bottom end opening of the light guide cover is connected to the middle notch of the exposure lamp, the camera is arranged parallel to the end of the light guide cover away from the reflective lens and the detection end of the camera is facing the reflective lens.

[0006] Preferably, the bottom of the exposure lamp is fixedly connected to a base frame, the base frame is a door-shaped fixed cover arranged on the aluminum-plastic cover conveyor belt, and detection ports are opened on the opposite side walls of the base frame.

[0007] Preferably, a mounting plate is connected between the exposure lamp and the light guide cover, the mounting plate is arranged horizontally, and the camera is fixed on the mounting plate.

[0008] Preferably, a support column is vertically connected between the cantilevered section of the mounting plate and the top surface of the base frame, and the support column is fixed between the mounting plate and the base frame by bolts.

[0009] Preferably, the reflective lens is arranged at 45° to the horizontal plane.

[0010] The utility model provides a mirror light detection device for the top surface of an aluminum-plastic cover. The camera is arranged horizontally, and an exposure lamp and a light guide cover are installed on a conveyor belt of the aluminum-plastic cover after the cover is turned over. After the aluminum-plastic cover is transported and irradiated by the exposure lamp, the optical fiber is reflected to the camera through a reflective lens in the light guide cover. The arrangement of the light guide cover can not only avoid the diffusion of the exposure light, but also shorten the height of the mirror light detection device for the top surface of the aluminum-plastic cover, so that the optical detection equipment of the aluminum-plastic cover has better integration, shortens the height difference between two sections of the conveyor belt of the aluminum-plastic cover, reduces the length of the belt, and reduces the volume and cost of the optical detection equipment.

[0016] like Figure 1 As shown, the utility model provides a mirror light detection device for the top surface of an aluminum-plastic cover, comprising an exposure lamp 2 fixed on a conveyor belt of the aluminum-plastic cover, a light guide cover 4 fixed on the top of the exposure lamp 2, and a camera 5 fixed on one side of the light guide cover 4, the exposure lamp 2 is an annular exposure lamp, the light guide cover 4 is hollow inside and forms an L-shaped internal light channel, a reflective lens 7 is obliquely fixedly installed at a corner inside the light guide cover 4, the bottom end opening of the light guide cover 4 is connected to the middle notch of the exposure lamp 2, the camera 5 is parallel to the end of the light guide cover 4 away from the reflective lens 7 and the detection end of the camera 5 is arranged toward the reflective lens 7.

[0017] The front section of the flipping mechanism of the aluminum-plastic cover is the aluminum-plastic cover vertical surface conveying belt, and the rear section is the aluminum-plastic cover top surface conveying belt. The top surface mirror light detection device is installed on the top surface conveying belt; the exposure lamp 2 and the lens inside the exposure lamp 2 are installed first, and wiring is carried out. After the wiring is completed, the mounting plate 3 is fixedly installed on the top of the exposure lamp 2. After the mounting plate 3 is installed, the light guide cover 4 and the camera 5 are installed according to the hole positions on the mounting plate 3. After the camera 5 is installed, a shooting test is carried out.

[0018] When the conveyor belt transports the turned-over aluminum-plastic cover to the front end of the exposure lamp 2, the grating arranged at the front end of the exposure lamp 2 detects the signal of the aluminum-plastic cover and transmits the signal to the exposure lamp 2. The exposure lamp 2 flashes and illuminates the aluminum-plastic cover. The light passes through the notch in the middle of the exposure lamp 2, passes through the light guide port 8, and is reflected by the reflective lens 7. Finally, it is photographed by the camera 5. The picture signal is transmitted to the PC. The image software compares the taken photo with the standard photo to determine whether the aluminum-plastic cover is qualified, thereby completing the top surface light detection of the aluminum-plastic cover.

[0019] like Figure 1 As shown, in order to prevent the strong exposure of the exposure lamp 2 from affecting the workers on the production line, the bottom of the exposure lamp 2 is fixedly connected to a base frame 1, and the base frame 1 is fixedly covered in a door shape on the aluminum-plastic cover conveyor belt, and detection ports are opened on the opposite side walls of the base frame 1. The detection ports are used by the workers to observe whether the exposure lamp 2 is working normally.

[0020] like Figure 1 and Figure 2 As shown, in order to facilitate the parallel arrangement of the light guide cover 4 and the camera 5. A mounting plate 3 is connected between the exposure lamp 2 and the light guide cover 4, the mounting plate 3 is arranged horizontally, and the camera 5 is fixed on the mounting plate 3. By arranging the mounting plate 3, when the height of the camera 5 is not enough, an isosceles trapezoidal structure bracket is installed at the bottom of the camera 5 to fix the camera 5.

[0021] like Figure 1 As shown, in order to improve the stability of the installation of the mounting plate 3, a support column 6 is vertically connected between the cantilever section of the mounting plate 3 and the top surface of the base frame 1, and the support column 6 is fixed between the mounting plate 3 and the base frame 1 by bolts. One end of the mounting plate 3 is fixedly mounted on the exposure lamp 2, and the support column 6 is processed according to the height difference between the mounting plate 3 and the base frame 1. The support column 6 is made of a plastic pipe, which is easy to process. Bolts are passed through the support column 6, and the other end of the bolts is locked on the base frame 1 to press the support column 6, so that the support column 6 is completely limited.

[0022] like Figure 1 and Figure 3 As shown, the most convenient arrangement of the reflective lens 7 is adopted to facilitate the installation of the camera 5. The reflective lens 7 is arranged at 45° to the horizontal plane.
