Description

Technical Field

[0001] This utility model relates to the field of sheet metal equipment technology, specifically an automatic adhesive removal device for edge rollers. Background Technology

[0002] In modern car body manufacturing processes, especially in the production of four doors and two hoods, the hemming process is increasingly used. Hemming typically requires the use of hemming wheels to hem sheet metal parts. To ensure a tight seal, the inner and outer panels of the sheet metal parts usually need to be coated with adhesive. This inevitably leads to adhesive getting onto the hemming wheels during the hemming process, affecting the hemming quality. Currently, it is common practice to manually wipe the adhesive off the hemming wheels after hemming a certain number of sheet metal parts, which is time-consuming, labor-intensive, and reduces production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an automatic glue removal device for the edge roller, which helps OEMs improve production efficiency and save labor costs, and enhances the automation of the production line, avoiding the need to stop the line and walk into the production line to manually remove glue.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] An automatic adhesive removal device for a edging wheel includes a grinding wheel, a support base, a motor, and an edging tool. The grinding wheel is connected to the power output shaft of the motor, and the motor body is fixedly connected to the support base. The edging tool includes an edging wheel and a moving mechanism. The edging wheel is connected to the lower end of the moving mechanism, and the edging wheel moves to the grinding wheel via the moving mechanism to remove adhesive.

[0006] In a further embodiment, the support base includes a mounting bracket, a base, and a bearing. The base is connected to the upper end of the mounting bracket, the bearing is disposed inside the base, the end of the grinding wheel is connected inside the bearing, and the grinding wheel is rotatably connected to the base through the bearing.

[0007] In a further embodiment, both ends of the grinding wheel are provided with bases and bearings, and the support base also includes a fixed base, which is located on one side of the base. The motor is fixed to the mounting bracket through the fixed base.

[0008] In a further embodiment, the roller bearing wheel has multiple angles, and the roller surfaces with multiple angles are used to make roller bearings with different angles. The grinding wheel has multiple roller surfaces with multiple angles that match and contact the roller bearing wheel, and the radii of the roller surfaces that match and contact the roller bearing wheel increase sequentially.

[0009] In a further embodiment, the roller has a groove on its body.

[0010] In a further embodiment, the moving mechanism includes a lateral moving component and a rotating component, the rotating component being connected to the lower end of the lateral moving component, and the roller being connected to the end of the rotating component that outputs rotation.

[0012] In a further embodiment, a coupling is connected between the power output shaft of the motor and the rotating shaft of the grinding wheel, and the motor drives the grinding wheel through the coupling.

[0013] In a further embodiment, a driver is connected to one side of the support base, and the motor's rotation speed and cycle are controlled by the driver.

[0014] In a further embodiment, a position sensor is connected to the upper end of the support base, and the position sensor is used to detect the positioning signal of the rolling tool above the grinding wheel.

[0026] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 As shown, an automatic adhesive removal device for a edging wheel includes a grinding wheel 2, a support base 20, a motor 4, and an edging tool 10. The grinding wheel 2 is connected to the power output shaft of the motor 4, and the body of the motor 4 is fixedly connected to the support base 20. The edging tool 10 includes an edging wheel 16 and a moving mechanism 15. The edging wheel 16 is connected to the lower end of the moving mechanism 15, and the edging wheel 16 is moved to the grinding wheel 2 by the moving mechanism 15 to remove adhesive.

[0028] Grinding wheel 2 generally includes a wheel body, such as Figure 3 The connecting shaft 5 and key 9 are shown. Key 9 is located on the middle surface of the connecting shaft 5. (Refer to...) Figure 1 As shown, key 9 is connected to the wheel body, and the wheel body is connected to the connecting shaft 5 via key 9, which allows the grinding wheel 2 to rotate synchronously with the connecting shaft 5. It is conceivable that the connecting shaft 5, key 9, and wheel body can also be integrated into a single unit.

[0029] like Figure 2 As shown, the support base 20 includes a mounting bracket 1, a base 8 and a bearing 7. The base 8 is connected to the upper end of the mounting bracket 1, the bearing 7 is disposed inside the base 8, the end of the grinding wheel 2 is connected inside the bearing 7, and the grinding wheel 2 is rotatably connected to the base 8 through the bearing 7.

[0030] The connecting shaft 5 of the grinding wheel 2 is mounted on the bearing 7, which reduces the force on the connecting shaft 5 in the direction of gravity.

[0031] Both ends of the grinding wheel 2 are provided with bases 8 and bearings 7. The support base 20 also includes a fixed base 19, which is located on one side of the base 8. The motor 4 is fixed to the mounting bracket 1 through the fixed base 19. This provides good support for both the grinding wheel 2 and the motor 4. It is conceivable that only two bases 8 could be used to install the motor 4 and the grinding wheel 2. For example, the base 8 and fixed base 19 near the motor 4 could be combined to install the motor 4 and the grinding wheel 2. Alternatively, other bushings could be used to adapt the connection between the motor 4 and the grinding wheel 2.

[0032] like Figure 1 As shown, the roller 16 has multiple angles, and the roller surfaces with multiple angles are used to make roller edges with different angles. The grinding wheel 2 has multiple roller surfaces with multiple angles that match and contact the roller 16, and the radius of the roller surfaces that match and contact the roller 16 increases sequentially.

[0033] The edging wheel 16 includes cylindrical wheels and / or tapered wheels, such as 35° tapered wheels 12 and 15° tapered wheels 13, and cylindrical wheels such as narrow cylindrical wheels 11 and finger wheels 14.

[0034] The moving mechanism 15 includes a lateral moving component 17 and a rotating component 18. The rotating component 18 is connected to the lower end of the lateral moving component 17, and the edge roller 16 is connected to the end of the rotating component 18 that outputs rotation. The lateral moving component 17, such as a lateral moving guide rail, drives the rotating component 18 and the edge roller 16 to move above the grinding wheel 2 for glue removal. When not removing glue, the rotating component 18 or the lateral moving component 17 moves to disengage the edge roller 16 from the grinding wheel 2. It is conceivable that the lateral moving component 17 can be driven by electric or pneumatic automatic mechanisms.

[0035] There are multiple hemming rollers 16, which are evenly distributed at the lower end of the moving mechanism 15. By arranging multiple hemming rollers 16 at the lower end of the moving mechanism 15, the hemming efficiency and glue removal efficiency of the hemming rollers 16 can be improved.

[0036] A coupling 3 connects the power output shaft of motor 4 to the rotating shaft of grinding wheel 2, and motor 4 drives grinding wheel 2 through coupling 3. Using coupling 3, such as a flexible coupling 3, can reduce installation errors and / or facilitate installation.

[0037] A driver 6 is connected to one side of the support base 20, and the motor 4 is controlled by the driver 6 to adjust its rotation speed and cycle. This facilitates adjusting the rotation speed of the grinding wheel 2, controlling the adhesive removal speed, and switching between grinding wheels 2. The motor 4 can be a stepper motor, which allows the driver 6 to be programmed with the step duration.

[0038] A position sensor is connected to the upper end of the support base 20. The position sensor is used to detect the positioning signal of the rolling tool 10 above the grinding wheel 2. This allows the motor 4 to start when the rolling wheel 16 is detected to be in the predetermined position and stop when it is disengaged, facilitating automatic control of the adhesive removal process.

[0039] For specific implementation methods, please refer to... Figure 1 As shown, the adhesive removal device for the edging wheel 16 is locked to the ground by the mounting bracket 1. The mounting bracket 1 is equipped with a motor 4 and a driver 6 to ensure the operation of the device. The motor 4 drives the connecting shaft 5 to rotate, and a coupling 3 is installed between the motor 4 and the connecting shaft 5 to eliminate the influence of misalignment. The grinding wheel 2 rotates synchronously with the connecting shaft 5. The grinding wheel 2 is provided with multiple working surfaces to facilitate the work of different models of edging wheels 16. The grinding wheel 2 is also designed with slots to facilitate the binding of a scouring pad to the grinding wheel 2 via a strap. The scouring pad can be replaced when it is damaged during grinding. The robot drives the roller on the edging tool 10 to approach the working surface of the grinding wheel 2 to perform adhesive removal operations to remove the adhesive from the surface of the edging wheel 16. After the adhesive removal operation of one type of edging wheel 16 is completed, the robot adjusts the posture of the edging tool 10 to perform adhesive removal on the next type of edging wheel 16 until all edging wheels 16 are completely removed. Then the edging tool 10 moves away, and the motor 4 stops.

[0040] like Figure 1 As shown, the rolling tool 10 drives the narrow cylindrical wheel 11 to approach the working surface of the grinding wheel 2 of the adhesive removal device to perform adhesive removal work.

[0041] like Figure 4 As shown, after the narrow cylindrical wheel 11 has finished cleaning the adhesive, it is switched to the 35° conical wheel 12 to approach the working surface of the grinding wheel 2 of the adhesive cleaning device to perform adhesive cleaning.

[0042] like Figure 5 As shown, after the 35° conical wheel 12 finishes cleaning the adhesive, it switches to the 15° conical wheel 13 to approach the working surface of the grinding wheel 2 of the adhesive cleaning device to perform adhesive cleaning.

[0043] like Figure 6 As shown, after the 15° conical wheel 13 finishes cleaning the adhesive, the process switches to the finger wheel 14 approaching the working surface of the grinding wheel 2 of the adhesive cleaning device to perform adhesive cleaning. When the finger wheel 14 finishes cleaning the adhesive, the robot leaves with the edge rolling tool 10, and the motor 4 stops rotating.
