[0027] Please refer to Figure 1 , Figure 2 , Figure 5 In an embodiment, an offline visual inspection device comprises a rack platform 1, the rack platform 1 is provided with an outer frame 3 through a support frame 2, the outer frame 3 is provided with a mounting frame 4, the mounting frame 4 is provided with an area light source 5, the center part of the area light source 5 is provided with a hollow area, one end of the camera detection module 6 is connected with the mounting frame 4, the other end of the camera detection module 6 extends towards the rack platform 1 through the hollow area, the area light source 5, the camera detection module 6 and the control box provided in the outer frame 3 are electrically connected.
[0028] Preferably, in the present embodiment, the off-line visual inspection device provided by the present application is used to detect whether the logo printed on the button of the remote controller is defective or missing, and also detects the appearance defects of the remote controller, such as scratches, stains, breakage, and concave, etc.
[0029] During the detection, the surface light source 5 can be a LED surface light source, which can provide a relatively uniform light distribution to ensure that each part of the product surface can be uniformly illuminated, so that the image obtained by the camera detection module 6 can more accurately reflect the appearance characteristics of the product. At the same time, under the irradiation of the surface light source 5, the reflection intensity of the scratch is different from that of the surrounding flat surface, the scratch will form a shadow or a weak reflection area, thereby forming a clear contrast with the normal surface, so that these defects can be more easily captured by the camera detection module 6. By setting the camera detection module 6, the image information of the product appearance can be accurately captured, and the detection of the product appearance can be completed in a short time, the detection effect is better, and it is not necessary to rest or adjust the state like manual detection, which greatly improves the detection efficiency.
[0030] At the same time, the image and detection result of each detection product can also be recorded by the visual inspection device, for example, in the detection of the remote controller, if it is found that there are appearance defects in a batch of products, the image and data recorded by the visual inspection device can be queried to accurately find out the problem link, while it is difficult for manual detection to record such comprehensive and accurate data.
[0031] Specifically, please refer to Figure 2 , Figure 4 , Figure 5 On the basis of the above embodiment, a strip light source 7 is further included, and a plurality of strip light sources 7 are arranged in a ring around the center of the camera module on the mounting frame 4, and the strip light source 7 is arranged obliquely with the mounting frame 4.
[0032] It is understood that in this embodiment, the strip light source 7 can be an LED strip light source, and the surface light source 5 mainly provides a relatively uniform light distribution to ensure that the entire surface of the product is illuminated. The strip light source 7 provides illumination from a specific annular tilt angle, and the combination of the two can provide multi-angle illumination for the product. For products like remote controls with complex shapes and surface features, multi-angle illumination allows all parts of the product to be detected under optimal lighting conditions. Through the complementary illumination of the strip light source 7 and the surface light source 5, the image acquired by the camera detection module 6 can contain more information about the product's appearance. When detecting various defects in the appearance of the remote control (such as scratches, stains, damage, dents, and logo defects), this more comprehensive lighting method can improve the accuracy of detection. Through the synergistic effect of the two light sources, the possibility of missed or false detections caused by uneven or incomplete illumination is reduced.
[0033] Specifically, please refer to Figure 1 , Figure 2 Based on the above embodiments, it also includes a hinge and a cabinet door 8. One end of the hinge is connected to the outer frame 3, and the other end of the hinge is connected to the cabinet door 8. It can be understood that by setting the cabinet door 8, it can provide protection for the internal camera detection module 6, etc. When maintenance is required, it can be easily opened through the cabinet door 8. At the same time, it can provide a shielding effect to prevent the strong light of the surface light source 5 and the strip light source 7 from causing damage to the workers' eyes during the detection process.
[0034] Specifically, please refer to Figure 1 Based on the above embodiments, it also includes fixture mounting holes 9, and a plurality of fixture mounting holes 9 are provided on the frame platform 1.
[0035] It is understandable that during the production process, it is necessary to inspect a variety of products of different types or sizes. Different products have different shapes, sizes and structures, and different fixtures are needed to fix and position the products to ensure that the position of the products is accurate and stable during visual inspection. The existence of fixture mounting holes 9 allows for the convenient installation of matching fixtures according to the needs of different products. Through the fixture mounting holes 9, the corresponding fixtures can be easily installed on the frame platform 1, so that the equipment can adapt to the inspection needs of different products.
[0036] Specifically, please refer to Figure 1 Based on the above embodiments, a controller 10 is also included. The controller 10 is mounted on the rack platform 1 and is electrically connected to the control box. It can be understood that by setting the controller 10, the vision inspection equipment can be started and stopped quickly, providing a quick operation function.
[0037] Specifically, please refer to Figure 1Based on the above embodiments, it also includes adjustable feet 11, and a plurality of adjustable feet 11 are provided at the bottom of the frame platform 1.
[0038] Preferably, the adjustable feet 11 used in this embodiment can be threaded adjustable feet. It is understood that in the actual production environment, the mounting surface of the vision inspection equipment may not be completely flat. For example, if it is installed on the floor of an old factory, the floor may have some unevenness. The adjustable feet 11 can be adjusted according to the actual situation of the mounting surface so that the equipment can be placed stably on the uneven surface and avoid the problem of the mounting surface affecting the normal operation of the equipment.
[0039] Specifically, please refer to Figure 1 , Figure 3 Based on the above embodiments, a cooling fan 12 is also included. A cooling fan 12 is provided on one side of the outer frame 3, and the cooling fan 12 is electrically connected to the control box.
[0040] It is understandable that in offline visual inspection equipment, the control box contains many electronic components, such as the control box and the camera inspection module 6, which generate heat when working. The cooling fan 12 continuously draws out the hot air from the outer frame 3 and introduces cold air, thereby reducing the temperature inside the control box, ensuring that the electronic components work within a suitable temperature range, extending their service life and ensuring the stable operation of the equipment.
[0041] Specifically, please refer to Figure 1 Based on the above embodiments, it also includes a display component and a placement rack 13. The placement rack 13 is rotatably connected to the outer frame 3. The display component is disposed on the placement rack 13 and is electrically connected to the control box. It can be understood that the display component includes a display screen, mouse, keyboard, etc., and is used to display various parameters and working status of the offline visual inspection equipment.
[0042] Specifically, please refer to Figure 1 , Figure 2 Based on the above embodiments, it also includes a speaker 14. The speaker 14 is provided on the outer frame 3 and is electrically connected to the control box. It can be understood that by providing the speaker 14, the test results of the product can be prompted to the worker through sound during the test process.
[0043] Specifically, please refer to Figure 1 Based on the above embodiments, a three-color indicator light 15 is also included. The three-color indicator light 15 is provided on the outer frame 3 and is electrically connected to the control box.
[0044] It is understandable that the tri-color indicator light 15 and the sound emitted by the speaker 14 work together to form a multi-sensory reminder mechanism. For employees, the dual stimulation of sight and hearing can more effectively attract their attention. When the product is found to be good, the green indicator light and the "Pass" sound appear simultaneously. Employees who hear the sound and see the green light at the same time will be more certain that the product is qualified. When the product is defective, the red indicator light and the "NG" alarm sound appear simultaneously. This dual reminder can reduce the possibility that employees will ignore the product inspection results due to focusing on a certain task.
[0045] In summary, when using the offline visual inspection equipment provided in this application, technicians first establish a product inspection template in the computer system and set the parameters. In standby mode, the product to be inspected is placed on the rack platform 1, ensuring it is within the range of the camera inspection module 6, surface light source 5, and strip light source 7. The controller 10 is then pressed, and the camera in the camera inspection module 6 takes a picture of the product placed on the rack platform 1, sending the image signal to the control box for processing. The control box compares the acquired image signal with the pre-established template. If all parameters match the set parameters, the visual system judges it as OK; otherwise, it is judged as NG. When the product is deemed OK, the tri-color indicator light 15 turns green, and the speaker 14 emits a "Pass" sound, reminding the employee that the product is good. The employee then manually removes the product and places it in the good product area for the next production process. When the product is deemed NG, the tri-color indicator light 15 turns red, and the speaker 14 emits an NG alarm sound, reminding the employee that the product is defective. The employee then manually removes the product for further inspection. The employee then places a new product to be inspected into the inspection range and repeats the above actions to inspect the appearance of multiple products. This setup allows for precise inspection, replacing manual labor, effectively reducing or avoiding missed inspections and inadequate inspections, and significantly improving the product yield.
