Description

Technical Field

[0001] This utility model relates to the technical field of adhesive scraping devices, specifically a dynamic control adhesive scraping device adapted to blind bonding profiles. Background Technology

[0002] After blind bonding of profiles, the quality of the adhesive layer directly determines the reliability and stability of the connection. Insufficient adhesive will result in weak bonding strength, making the profile prone to detachment under subsequent vibration or stress conditions; excessive adhesive will cause it to overflow from the edges of the profile, contaminating the surrounding area, affecting not only the appearance but also potentially causing adjacent components to stick together and interfering with normal equipment operation. Therefore, the adhesive scraping device needs to be able to precisely control the amount of adhesive dispensed. Existing dynamic control adhesive scraping devices for blind bonding profiles can basically meet daily usage needs, but there are still some shortcomings that need improvement.

[0003] Currently, most widely used dynamic control scraping devices for blind bonding profiles employ fixed-parameter mechanical scraping structures or simple pressure feedback control methods. While these devices can generally meet the needs of daily low-precision bonding operations under ideal conditions where the adhesive viscosity is stable, the scraping head is brand new, and the working environment is constant, the edges of the scraping head will wear down after long-term operation. Although this slight wear is difficult to detect with the naked eye, it will lead to a larger scraping gap, causing deviations in the adhesive layer thickness and thus affecting the scraping effect. Therefore, we propose a dynamic control scraping device adapted to blind bonding profiles to solve the above problems. Summary of the Invention

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0018] This utility model provides a technical solution as follows: Figures 1 to 4 As shown in this embodiment, a dynamic control scraping device adapted to blind bonding lines includes a processing table 1. Side seats 2 are installed on both sides of the top of the processing table 1. A crossbeam 3 is installed on the upper end of the two sets of side seats 2. A lead screw 5 is rotatably connected inside the crossbeam 3. A drive motor 4 is installed on the side end of the side seat 2. The output end of the drive motor 4 is connected to the end of the lead screw 5. A movable seat 7 is provided on the outside of the crossbeam 3. A threaded sleeve 6 is threadedly connected to the outside of the lead screw 5. The threaded sleeve 6 is externally connected to the rear end of the movable seat 7. Guide grooves 9 are opened at both the upper and lower ends of the crossbeam 3. Guide plates 8 are installed on both the upper and lower sides of the rear end of the movable seat 7. The two sets of guide plates 8 are located in the two sets of guide grooves 9. A linear driver 10 is installed at the front end of the movable seat 7. A scraper 11 is installed at the output end of the linear driver 10. A vision inspection camera 12 is installed at the front end of the movable seat 7. A laser detection module 13 is installed at the front end of the two sets of side seats 2.

[0019] By installing a four-way adjustable scraper 11 on the processing table 1, the drive motor 4 can drive the lead screw 5 to rotate, the threaded sleeve 6 can drive the movable seat 7 to move horizontally along the crossbeam 3, and the guide plate 8 can cooperate with the guide groove 9 to ensure smooth movement. The linear driver 10 can vertically adjust the height of the scraper 11. The visual inspection camera 12 set on the movable seat 7 and the laser detection module 13 installed at the front of the two sets of side seats 2 can monitor the scraping status and adhesive layer thickness in real time, so as to achieve precise positioning and height adjustment of the scraper 11. The combination of vision and laser sensing realizes dynamic feedback control, improves the scraping accuracy and consistency, and effectively avoids the problem of adhesive layer thickness deviation.

[0020] In other embodiments, a control panel 14 is mounted on the outside of the side seat 2. The control panel 14 is electrically connected to the drive motor 4, the linear driver 10, the vision inspection camera 12 and the laser detection module 13 via wires. This design enables the control panel 14 to integrate the control system, receive sensor data and output control commands, achieve automated regulation, and improve the ease of operation and system response speed.

[0021] In other embodiments, the scraper 11 is a detachable structure, and its scraping blade is made of cemented carbide. This design allows the scraper 11 to be fixed to the output end of the linear driver 10 by bolts, enabling the scraper 11 to be quickly replaced after wear. The use of carbide extends the service life of the scraper 11 and ensures the precision of the scraper 11's edge.

[0022] In other embodiments, the outer wall of the guide plate 8 is fully fitted with the inner wall of the guide groove 9, and the guide plate 8 and the guide groove 9 are slidably connected. This design allows the movable seat 7 to move laterally along the two sets of guide plates 8 within the two sets of guide grooves 9 on the crossbeam 3, effectively preventing the movable seat 7 from shaking during movement and improving the stability of the movable seat 7 during movement.

[0023] In other embodiments, multiple sets of laser displacement sensors are installed at equal intervals at one end of each of the two sets of laser detection modules 13. This design allows multiple laser displacement sensors to continuously detect the distance between the scraper 11 and the workpiece, and the data is fed back to the control panel 14 to adjust the linear driver 10 to maintain the optimal scraping gap, compensate for the gap changes caused by the wear of the scraper 11, and keep the adhesive layer thickness stable.

[0024] In other embodiments, a transparent protective cover is provided on the outer wall of the front end of the visual inspection camera 12; This design allows the transparent cover to protect the lens on the visual inspection camera 12 from damage caused by external contact.

[0025] This utility model provides a dynamic adjustment adhesive scraping device adapted to blind bonding lines, and its specific working principle is as follows: Place the blind-bonded profile workpiece on the processing table 1, start the system on the control panel 14, set the scraping speed, preset adhesive layer thickness, and other process parameters for this operation, start the drive motor 4, drive the lead screw 5 to rotate, drive the threaded sleeve 6 and the connected movable seat 7 to move along the crossbeam 3, the guide plate 8 slides in the guide groove 9, the vision inspection camera 12 at the front end of the movable seat 7 scans the area of ​​the profile to be scraped, acquires the image and transmits it to the control panel 14, and makes a preliminary judgment on the approximate distribution of the existing adhesive, providing a basis for scraping path planning, then move the movable seat 7 to the scraping starting point, let the linear actuator 10 extend according to the preset parameters, so that the scraper 11 descends to an initial height close to the workpiece surface, the laser detection module 13 accurately measures the actual distance between the scraper 11 cutting edge and the surface of the profile workpiece, and transmits the data. The system continuously captures images of the glue layer after scraping, providing real-time feedback to the control panel 14. This monitors the width of the glue layer, the neatness of its edges, and whether there is any glue overflow or missing glue. The drive motor 4 continues to work, driving the movable seat 7 and the scraper 11 to perform the scraping operation smoothly at a set speed. If the distance value fed back by the laser detection module 13 is greater than the preset ideal scraping gap, it indicates that the scraper 11 has been worn. The control system immediately sends a command to the linear driver 10 to extend it slightly and lower the scraper 11 by the corresponding compensation amount, thereby maintaining a constant scraping gap and ensuring that the glue layer thickness remains unchanged. If the visual inspection camera 12 detects glue overflow or uneven width, the control system can make a comprehensive judgment and adjust the pressure of the linear driver 10 or the moving speed of the drive motor 4 to correct the scraping effect in a timely manner.

[0026] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.
