[0021] The following is a clear and complete description of a visual inspection device for photographs according to the present invention, with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, the present invention provides a visual inspection device for photographs, including a frame 1, an inspection platform 2, a conveyor belt 3, and a drive cylinder 4.

[0023] The rack 1 has an electrical control cabinet 10 installed on one side, which contains a control module. The control module can be an STM322211F03220C877 control chip, etc. A gantry frame is installed on the surface of the rack 1, and a vision inspection component is installed on the top of the gantry frame. The vision inspection component includes an industrial camera 5, a light source 6, and a linear module 7 for driving the industrial camera 5 and the light source 6 to move. The vision inspection component is connected to the control module for image acquisition, transmission processing, and execution of corresponding operations. This is existing technology and will not be described in detail here.

[0024] The detection platform 2 is rotatably mounted on the surface of the frame 1 and located below the visual inspection component. Specifically, a rotating bracket 16 is mounted on the surface of the frame 1, and one bottom side of the detection platform 2 is rotatably connected to the rotating shaft of the rotating bracket 16. A drive cylinder 4 is mounted on the frame 1, located on the other side of the detection platform 2, with its drive end hinged to the detection platform 2. The extension and retraction of the drive cylinder 4 drives the detection platform 2 to rotate and adjust its angle. The drive cylinder 4 is connected to the control module for control.

[0025] The conveyor belt 3 is installed on the testing platform 2 to transport the glass photographs 8 to the testing position. At the same time, a loading conveyor platform 9 is installed on one side of the frame 1. The loading conveyor platform 9 receives the conveyor belt 3 and is used for loading. In addition, a lifting baffle 11 is provided at the unloading end of the conveyor belt 3. The lifting baffle 11 is installed on the testing platform 2 and is used to pre-position the glass photographs 8 to be tested. A telescopic cylinder 12 is installed on the lifting baffle 11 to drive the lifting baffle 11 to rise and fall. The telescopic cylinder 12 is connected to the control module for control.

[0026] After the glass photograph 8 to be inspected is transported to the inspection position, the visual inspection component inspects the glass photograph 8. During the inspection process, the control module can control the drive cylinder 4 to drive the inspection platform 2 to rotate the conveyor belt 3, so as to adjust the angle of the glass photograph 8 and ensure the accuracy of the inspection results.

[0027] It should be noted that the glass photograph 8 will shift during the process of being transported to the detection position, which will increase the difficulty of detection. Therefore, it is necessary to set up a correction component to correct and position the glass photograph 8.

[0028] The correction assembly is symmetrically installed on both sides of the conveyor belt 3, and includes a mounting frame 13, a translation cylinder 14, and a positioning clamp 15.

[0029] The mounting bracket 13 is installed on both sides of the conveyor belt 3, the translation cylinder 14 is installed on the surface of the mounting bracket 13, and the positioning clamp 15 is installed on the drive end of the translation cylinder 14. When the glass photograph 8 reaches the detection position, the translation cylinder 14 drives the positioning clamp 15 to move horizontally to correct and position the glass photograph 8, making it horizontal so that the visual inspection component can perform the inspection. At the same time, the positioning clamp 15 can also clamp and fix the glass photograph 8 to prevent it from slipping off the conveyor belt 3 during the change of angle, ensuring the safety of the inspection. The translation cylinder 14 is connected to the control module.

[0030] It should be noted that this device is also equipped with multiple sensors, such as distance sensors. These sensors are connected to the control module to detect the position of the glass photograph 8 and transmit the detection information to the control module for processing. This is existing technology and will not be described in detail here.

[0031] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] The various modifications described in these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
