Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass primer detection, in particular to a primer detection device. Background Art
[0002] Before installing the automobile glass, various related accessories are usually bonded. In order to ensure the bonding firmness and sealing of the accessories on the glass, the current bonding process is to apply the activator and primer on the glass in sequence, and then apply the glue. In order to ensure the bonding quality, it is necessary to test the coating accuracy of the activator and primer and the quality of the glue. The current detection methods include: offline visual inspection, plane tracking inspection, and manual inspection. Among them, offline inspection requires the product to be removed from the production line for inspection, which not only wastes the robot beat and affects the production rhythm, but also because the activator and primer have the characteristics of quick drying, especially for large-sized glass such as panoramic sunroofs, the coating time is long. When the coating is completed, the activator and primer applied first are already in a dry state, which is easy to cause false detection. Due to the fast detection speed and production beat of plane tracking inspection, the camera with tracking cannot fully cover the glass to be inspected, resulting in low detection accuracy. Due to the influence of subjective factors and visual fatigue of personnel, manual inspection is not only inefficient, but also has low detection accuracy. Utility Model Content

[0006] Furthermore, a computing card is arranged on the installation disk, and the computing card is communicatively connected with the industrial camera.
[0007] Furthermore, the mounting plate is provided with a plurality of visual detection components arranged around the avoidance holes.

[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.
[0017] Before installing the automobile glass, various related accessories are usually bonded. In order to ensure the bonding firmness and sealing of the accessories on the glass, the current bonding process is to apply the activator and primer on the glass in sequence, and then apply the glue. In order to ensure the bonding quality, it is necessary to test the coating accuracy of the activator and primer and the quality of the glue. The current detection methods include: offline visual inspection, plane tracking inspection, and manual inspection. Among them, offline inspection requires the product to be removed from the production line for inspection, which not only wastes the robot beat and affects the production rhythm, but also because the activator and primer have the characteristics of quick drying, especially for large-sized glass such as panoramic sunroofs, the coating time is long. When the coating is completed, the activator and primer applied first are already in a dry state, which is easy to cause false detection. Due to the fast detection speed and production beat of plane tracking inspection, the camera with tracking cannot fully cover the glass to be inspected, resulting in low detection accuracy. Due to the influence of subjective factors and visual fatigue of personnel, manual inspection is not only inefficient, but also has low detection accuracy.
[0018] Based on this, the present application provides a primer detection device that can solve the problem of low primer quality detection accuracy and easy impact on the subsequent accessory bonding quality.
[0019] Please refer to Figure 1 and Figure 2 As shown, the utility model is a primer detection device, comprising a mounting plate 1 and a visual detection component 2 arranged on the mounting plate 1; the mounting plate 1 has an avoidance hole 11 for a coating tool to pass through;
[0020] The visual inspection component 2 includes a line laser 21 and an industrial camera 22; the line laser emitted by the line laser 21 irradiates the path coated by the coating tool, and the industrial camera 22 is used to obtain a point cloud image of the line laser emitted by the line laser 21 on the path coated by the coating tool.
[0021] From the above description, it can be known that the beneficial effect of the utility model is: adding a mounting plate 1 with an avoidance hole 11, so that the coating tool and the mounting plate 1 can be pressed at the end of the robot, and at the same time, a visual inspection component 2 is added to the mounting plate 1, so that when the robot drives the coating tool to coat the activator or primer or adhesive on the glass, the industrial camera 22 can obtain the point cloud image of the line laser emitted by the line laser 21 on the path coated by the coating tool, and then the computer can compare the obtained point cloud image with the sample image to determine whether the coating quality is qualified. The coating quality is inspected while coating, thereby ensuring the inspection progress and preventing the drying of the activator or primer from affecting the bonding quality of the accessories.
[0022] Furthermore, a computing card (not shown) is arranged on the installation disk 1, and the computing card is connected to the industrial camera 22. The computing card is not shown in the figure because the installation position of the computing card on the installation disk 1 is relatively flexible and only needs not to affect the operation of the visual inspection component 2 and the movement of the end of the manipulator.
[0023] From the above description, it can be seen that since the industrial camera 22 needs to capture a large number of images to construct a point cloud model, in order to reduce bandwidth occupancy and packet loss during long-distance transmission, a computing card is set on the installation disk 1.
[0024] Please refer to Figure 1 and Figure 2 As shown, further, a plurality of visual detection components 2 arranged around the avoidance hole 11 are provided on the mounting plate 1. Preferably, three visual detection components 2 arranged around the avoidance hole 11 are provided on the mounting plate 1, and the line connecting two adjacent visual detection components 2 to the avoidance hole 11 forms an angle of 120°. The line lasers emitted by the line lasers 21 of two adjacent visual detection components 2 form an angle of 50° to 70°. Most preferably, the line lasers emitted by the line lasers 21 of two adjacent visual detection components 2 form an angle of 60°.
[0025] From the above description, it can be seen that in actual production, in order to meet the coating requirements of large-size glass such as panoramic sunroof glass, the trajectory of the robot is often complex and changeable, and the detection field of view of a single visual inspection component 2 cannot cover the entire coating area. Therefore, a plurality of visual inspection components 2 arranged around the avoidance hole 11 are provided on the mounting plate 1, and the plurality of visual inspection components 2 complement each other's field of view for inspection.
