Description

Technical Field

[0001] This utility model belongs to the field of industrial adhesive application technology, and specifically relates to an adhesive application trajectory visual correction device. Background Technology

[0002] In industrial adhesive application, the accuracy of the adhesive application trajectory directly determines the sealing performance, structural strength, and appearance quality of a product. Especially in high-precision applications such as automotive manufacturing, electronic component packaging, and medical device assembly, even minute deviations in adhesive application can lead to product scrap or performance failure. Currently, most mainstream adhesive application equipment relies on preset mechanical trajectories. However, in actual production, factors such as substrate conveying deviation, wear of the adhesive rollers, and changes in adhesive flowability due to ambient temperature variations can easily cause problems such as trajectory deviation, adhesive breakage, and adhesive overflow.

[0003] To address the issue of adhesive application trajectory deviation, some devices have begun to incorporate visual monitoring technology. This technology uses cameras to capture the adhesive application trajectory and compares it with a preset standard trajectory, thereby triggering a correction action. However, existing visual correction devices have significant technical shortcomings: First, the background environment significantly affects the accuracy of visual monitoring. Most devices use a fixed background plate, and when the contrast between the adhesive color and the background color is low (e.g., light-colored adhesive with a light-colored background, or dark-colored adhesive with a dark-colored background), the camera struggles to clearly identify the adhesive edge, leading to increased error in deviation judgment. Second, the coordination between the camera and the adhesive roller is insufficient. Existing devices mostly use fixed cameras or manually adjust the camera position, making it impossible to adjust the monitoring angle synchronously in real time according to the working position of the adhesive roller, which easily leads to blind spots, especially in scenarios of continuous adhesive application on long-sized substrates, making it difficult to achieve full-trajectory coverage monitoring. Third, the background adjustment mechanism and the camera adjustment mechanism are controlled independently, and their movements are not synchronized, which not only increases the complexity of equipment control but may also cause monitoring data lag due to adjustment delays, affecting the timeliness of correction. In addition, the transmission structure of some devices lacks stability, and during long-term, high-frequency adjustments, problems such as component loosening and displacement deviation are prone to occur, further reducing the correction accuracy and equipment lifespan.

By setting a background switching mechanism in the frame, a suitable background can be switched according to the adhesive application situation, which facilitates subsequent visual monitoring by the camera. This allows for all-round visual capture of the adhesive application trajectory of the adhesive roller. If a trajectory deviation is detected, the correction mechanism will be activated to correct the deviation.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A visual correction device for adhesive application trajectory includes a frame and a correction mechanism. The correction mechanism is fixedly connected inside the frame.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-5 As shown, a visual correction device for adhesive application trajectory includes a frame 1 and a correction mechanism. The correction mechanism is fixedly connected inside the frame 1. An adhesive application roller 5 is rotatably connected inside the frame 1, located above the correction mechanism. A lead screw 8 is rotatably connected inside the frame 1. A second servo motor 3 is fixedly connected to the outside of the frame 1, with one end of the second servo motor 3 penetrating inside the frame 1 and fixedly connected to one end of the lead screw 8. A connecting block 9 is threadedly connected to the outside of the lead screw 8. A first limiting member is fixedly connected inside the frame 1 and above the lead screw 8. The lower side of the first limiting member is fixedly connected to the upper side of the connecting block 9. A background switching mechanism is fixedly connected to the lower side of the connecting block 9, located on the side of the correction mechanism and the adhesive application roller 5. An additional bracket 2 is fixedly connected to one side of the frame 1. A screw 6 is rotatably connected inside the additional bracket 2. A camera 12 is threadedly connected to the outside of the screw 6. A second limiting member is fixedly connected inside the additional bracket 2, with one side of the second limiting member fixedly connected to one side of the camera 12. A transmission component is installed on the outside of the additional bracket 2. One end of the screw 6 is fixedly connected to the end of the bracket 1. The transmission component is connected to the second servo motor 3. When the position needs to be adjusted to achieve precise visual monitoring and background switching, the second servo motor 3 starts, and its output end drives the lead screw 8 that runs through the inside of the frame 1 to rotate. Since the lead screw 8 is threadedly connected to the connecting block 9, the rotation of the lead screw 8 will cause the connecting block 9 to move along the axial direction of the lead screw 8. At the same time, the first limiting component located on the upper side of the lead screw 8 in the frame 1 can limit the movement direction of the connecting block 9 to ensure its stable movement. The background switching mechanism on the lower side of the connecting block 9 moves with the connecting block 9 and can switch the appropriate background according to the glue application situation to facilitate subsequent visual monitoring. In the additional bracket 2, the second servo motor 3 drives the screw 6 to rotate through the transmission component. The screw 6 is threadedly connected to the camera 12, and the second limiting component in the additional bracket 2 limits the movement direction of the camera 12, so that the camera 12 moves stably with the rotation of the screw 6, thereby performing all-round visual capture of the glue application trajectory of the glue application roller 5. If a trajectory deviation is detected, the correction mechanism will be activated to correct it.

[0024] like Figure 2 , Figure 3 ,like Figure 4As shown, the correction mechanism includes two mounting brackets 15, which are fixedly connected inside the frame 1. Both mounting brackets 15 have an open top structure. Two sliding rods 16 are fixedly connected inside each mounting bracket 15, and sliders 17 are slidably connected to the outer sides of the two sliding rods 16. An L-shaped bracket is fixedly connected to one side of one mounting bracket 15, and a first servo motor 4 is fixedly connected to one side of the L-shaped bracket. The output end of the first servo motor 4 passes through the L-shaped bracket and is fixedly connected to one end of one of the sliders 17. Correction rollers 11 are fixedly connected to the upper sides of both sliders 17. When a deviation in the adhesive application trajectory needs correction, the first servo motor 4 starts, and its output end passes through the L-shaped bracket, driving one of the sliders 17 fixed thereto to move along the sliding rod 16. Since the correction rollers 11 are fixedly connected to the upper sides of both sliders 17, the movement of one slider 17 will drive the other slider 17 to move synchronously, thereby causing the correction rollers 11 to move accordingly. By adjusting the position of the correction rollers 11, the adhesive application trajectory is corrected, ensuring that the adhesive application trajectory meets the preset requirements.

[0025] like Figure 4 , Figure 5 As shown, the background switching mechanism includes a rectangular housing 10, which has a hollow structure with openings on both sides. Two rotating rollers 19 are rotatably connected inside the rectangular housing 10, and a background cloth 18 is driven to the outside of the two rotating rollers 19. A third servo motor 7 is fixedly connected to the lower side of the rectangular housing 10. The output end of the third servo motor 7 passes through the rectangular housing 10 and is fixedly connected to the lower end of one of the rotating rollers 19. When it is necessary to switch the background according to the glue application environment and monitoring requirements, the third servo motor 7 is started, and its output end passes through the rectangular housing 10 and drives one of the rotating rollers 19 to rotate. Under the transmission action, the other rotating roller 19 rotates accordingly. The two rotating rollers 19 together drive the background cloth 18 to move, realizing the switching of different areas of the background cloth 18, providing a clear and suitable background environment for the camera 12 to capture the glue application trajectory, and improving the accuracy of visual monitoring.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the transmission component includes two pulleys 14. One pulley 14 is fixedly connected to the peripheral side of the output end of the second servo motor 3, and the other pulley 14 is fixedly connected to the outside of the auxiliary bracket 2 and to one end of the screw 6. A conveyor belt 13 is connected between the two pulleys 14. When the second servo motor 3 starts, its output end drives the pulley 14 fixed to it to rotate. Through the transmission action of the conveyor belt, the other pulley 14 rotates accordingly, thereby driving the screw 6 fixed to the pulley 14 to rotate. This realizes the transmission of power from the second servo motor 3 to the screw 6, providing power for the movement of the camera 12, increasing the ability of the camera 12 to adjust its position with the operation of the second servo motor 3, and effectively monitoring the adhesive application trajectory.

[0027] like Figure 1 , Figure 2 , Figure 4 As shown, the two mounting brackets 15 are set at a 45° angle. During the correction process, this angle setting allows the correction roller 11 to correct the direction of the glue application trajectory in accordance with the actual needs of the glue application operation, which can adjust the deviation of the glue application trajectory more efficiently and accurately, and further improve the accuracy of the glue application trajectory.

[0028] like Figure 1 , Figure 2 As shown, the first limiting component includes a first round rod, which is fixedly connected to the inside of the frame 1. A first sliding sleeve is slidably connected to the outside of the first round rod, and the lower end of the sliding sleeve is fixedly connected to the upper end of the connecting block 9. The second limiting component includes a second round rod, which is fixedly connected to the inside of the auxiliary bracket 2. A second sliding sleeve is slidably connected to the outside of the second round rod, and one end of the second sliding sleeve is fixedly connected to one end of the camera 12. When the connecting block 9 rotates and moves with the lead screw 8, the first sliding sleeve will slide synchronously along the first round rod. Since the position of the first round rod is fixed, it can restrict the connecting block 9 to move only along the axial direction of the first round rod and the lead screw 8, reducing the offset or shaking of the connecting block 9 during movement, and increasing the stability of the movement of the connecting block 9 and the background switching mechanism. At the same time, when the camera 12 rotates and moves with the screw 6, the second sliding sleeve slides along the second round rod. The second round rod restricts the movement direction of the camera 12, increasing the stability of the camera 12 to move only along the axial direction of the second round rod and the screw 6, reducing the position offset of the camera 12 during monitoring, and increasing the accuracy of visual monitoring.

[0029] like Figure 5 As shown, the background cloth 18 has multiple color areas. When the camera 12 performs visual monitoring of the adhesive application trajectory, it can switch different color areas on the background cloth 18 as the monitoring background according to the color and material of the adhesive and the lighting conditions of the surrounding environment. Different color areas can form different contrasts with the adhesive. When the contrast between the adhesive and the background color is high, the camera 12 can capture the details of the adhesive application trajectory more clearly, accurately identify whether there is a deviation in the adhesive application trajectory, provide a more reliable visual basis for subsequent correction work, and improve the accuracy and reliability of adhesive application trajectory monitoring.

[0030] The working principle of this utility model is as follows: When it is necessary to adjust the position to achieve accurate visual monitoring and background switching, the second servo motor 3 starts, and its output end drives the lead screw 8 that runs through the inside of the frame 1 to rotate. Since the lead screw 8 is threadedly connected to the connecting block 9, the rotation of the lead screw 8 will cause the connecting block 9 to move along the axial direction of the lead screw 8. At the same time, the first limiting member located on the upper side of the lead screw 8 in the frame 1 can limit the movement direction of the connecting block 9 to ensure its stable movement. The background switching mechanism on the lower side of the connecting block 9 moves with the connecting block 9 and can switch the appropriate background according to the glue application situation, which is convenient for subsequent visual monitoring. In the additional bracket 2, the second servo motor 3 drives the screw 6 to rotate through the transmission component. The screw 6 is threadedly connected to the camera 12, and the second limiting member in the additional bracket 2 limits the movement direction of the camera 12, so that the camera 12 moves stably with the rotation of the screw 6, thereby performing all-round visual capture of the glue application trajectory of the glue application roller 5. If a trajectory deviation is detected, the correction mechanism will be activated to correct it.
