Description

Technical Field

[0001] This utility model relates to the technical field of product testing, and more specifically, to an image testing error prevention device. Background Technology

[0002] The top cover welding production line involves various product types and processes, and the following problems are prone to occur during production: incomplete welds, substandard welding quality, and reversed welds. These issues necessitate full product inspection by employees, increasing labor costs and potentially leading to the outflow of substandard products. To address these problems, such as... Figure 2 As shown, our company fixes the camera on the equipment column and connects it to the detection computer. Qualified products are placed on the fixtures on the workbench, and the camera takes pictures of the products to confirm the correct positioning of the welded products. System parameters are then set, and the process begins. After welding, the equipment's PLC sends a signal to the camera to take another picture of the product. The detection computer analyzes and compares the images, and if there are any issues such as missed welds or weld position misalignment, an alarm is triggered. Due to the large number of product types and processes, adjusting the camera's shooting angle is necessary to ensure accurate product images when performing different models and processes. Manual adjustment of the camera position by staff is cumbersome and inaccurate. Alternatively, different workbenches and cameras can be configured for different models and processes, but this increases space and equipment costs. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0015] like Figure 1 As shown, this utility model discloses an image detection error prevention device, including two columns 1 symmetrically connected to the left and right sides of a workbench. A lifting column 2 is slidably connected in the inner cavity of the column 1. The two lifting columns 2 are connected by a fixing rod 6. The lower end face of the middle part of the fixing rod 6 is fixedly connected to the lifting rod of the electric lifting device 16. A horizontally arranged first support plate 3 is connected to the top of the lifting column 2. The first support plate 3 is connected to a horizontally arranged second support plate 4 through several shock-absorbing springs 17. A vertically arranged seat plate 5 is connected to the middle of the second support plate 4. A horizontally arranged screw transmission mechanism is connected to the seat plate 5. A U-shaped seat 8 is connected to the transmission nut 7 of the screw transmission mechanism. A mounting base 10 is connected to the U-shaped seat 8 through a rotating shaft 9. A camera 11 is installed in the mounting base 10. The camera 11 and the electric lifting device 16 are both electrically connected to a detection computer.

[0016] In a specific embodiment of this application, based on the production operations of different product models and different processes, the camera position parameters, including the camera's longitudinal position, lateral position, and angle, are preset in the detection computer. During the specific production process, when changing models and / or performing different processes, different tooling is first used on the workbench to fix the product. Then, the preset parameters corresponding to the model change and / or different processes are retrieved from the detection computer and activated. The detection computer controls the electric lifting device 16 to drive the lifting column 2 to a suitable longitudinal position, and controls the driver 13 to drive the transmission nut 7 to a suitable lateral position. These actions cause the camera 11 to move to the suitable longitudinal and lateral positions. The detection computer then controls the driver 2 15 to drive the rotating shaft 9 to rotate, thereby rotating the camera 11 to a suitable angle. A distance sensor 1 (electrically connected to the detection computer) is set in the longitudinal direction opposite to the transmission nut 7, and a distance sensor 2 (electrically connected to the detection computer) is set in the lateral direction opposite to the transmission nut 7. The distance sensors 1 and 2 respectively identify the longitudinal and lateral positions. An angle sensor (electrically connected to the detection computer) is installed on the rotating shaft 9 to identify the angle of the camera 11. High-frequency vibrations on high-production production lines are often transmitted to cameras. On the one hand, the vibrating camera will affect its shooting effect, and on the other hand, long-term vibration will cause it to shift slightly. Therefore, in this application, a shock-absorbing spring 17 is provided between the first support plate 3 and the second support plate 4 to reduce the vibration of the camera.

[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
