[0025] This application provides a film bonding system 10 for vehicle exterior body panels. Figure 1 This is a schematic diagram of an embodiment of the film bonding system 10 for vehicle exterior coverings provided in this application.

[0026] Combination Figure 1 The film bonding system 10 for the vehicle exterior covering 21 includes an image acquisition device 11 and a laser emitting device 12. The image acquisition device 11 is used to acquire images of the exterior covering 21, and the laser emitting device 12 is used to emit a laser beam to the exterior covering 21.

[0027] Specifically, the image acquisition device 11 is a device capable of capturing images of the outer cover 21, such as a device with camera and video recording functions. The laser emitting device 12 can be any device capable of emitting a laser beam in the prior art, and is not specifically limited in this embodiment.

[0028] The film bonding system 10 for the vehicle exterior panel may further include a positioning fixture (not shown) for supporting and positioning the exterior panel 21, so that the exterior panel 21 is located in a specific area, allowing the laser beam to be projected onto a specific position on the exterior panel 21. A limiting structure may be provided on the positioning fixture, which limits the exterior panel 21 when it is placed on the positioning fixture, ensuring that the exterior panel 21 is located in the specific area.

[0029] Furthermore, the film bonding system 10 for the vehicle exterior panel also includes a control device (not shown), which is connected to the image acquisition device 11 and the laser emitting device 12, thereby enabling the control device to control the image acquisition device 11 and the laser emitting device 12. The connection between the control device and the image acquisition device 11 and the laser emitting device 12 can be wired or wireless; this embodiment does not impose specific limitations.

[0030] In conjunction with the configuration of the control device, the control device is used to receive and process images to obtain the type of the outer cover 21. The control device determines the bonding position 22 of the reinforcing film on the surface of the outer cover 21 according to the type, and controls the laser emitting device 12 to emit a laser beam to form the corner point and / or edge line of the bonding position 22.

[0031] Specifically, the control device can control the image acquisition device 11 to acquire images, or the image acquisition device 11 can automatically acquire images. After acquiring an image, the image acquisition device 11 transmits the image to the control device for image processing. The control device can store feature information of different types of outer coverings 21. After acquiring the image information of the current outer covering 21, it compares it with the stored feature information to determine the type of outer covering 21. Furthermore, different outer coverings 21 correspond to different pasting positions 22; therefore, the corresponding pasting position 22 can be determined based on the type of outer covering 21.

[0032] The adhesive placement 22 typically corresponds to corner points and edges. For example, if the adhesive placement 22 is rectangular, then it will have four corner points and four edges. After the corner points and / or edges of the adhesive placement 22 are formed by the laser beam, the adhesive placement 22 of the reinforcing film can be determined. This allows the reinforcing film to be adhered more accurately, thereby improving the quality of the outer cover 21.

[0033] Continue to combine Figure 1In some specific embodiments, the laser emitting device 12 includes a first laser emitting device 121 and a second laser emitting device 122, which are used to emit a first laser beam and a second laser beam, respectively, so that the first laser beam and the second laser beam can intersect on the surface of the outer cover 21 to form a corner point, or can form two edge lines on the surface of the outer cover 21.

[0034] Specifically, the first laser emitting device 121 and the second laser emitting device 122 can be functionally identical laser emitting devices 12, both controlled by the control device. In this case, one function of the first and second laser beams is to form corner positions by intersecting, thereby indicating the corner points of the pasting position 22 to the user, facilitating pasting. A second function of the first and second laser beams is to form the two edge lines of the pasting position 22.

[0035] Continue to combine Figure 1 Furthermore, in some specific embodiments, the laser emitting device 12 also includes a third laser emitting device 123 and a fourth laser emitting device 124, with the first laser emitting device 121, the second laser emitting device 122, the third laser emitting device 123, and the fourth laser emitting device 124 respectively disposed around the positioning fixture. Figure 1 The image merely illustrates one possible arrangement of the first laser emitting device 121, the second laser emitting device 122, the third laser emitting device 123, and the fourth laser emitting device 124, and is not intended to limit the application. In some applications, the first laser emitting device 121, the second laser emitting device 122, the third laser emitting device 123, and the fourth laser emitting device 124 may be arranged around the positioning fixture, or in four different locations within the positioning fixture.

[0036] The laser beams emitted by the first laser emitting device 121, the second laser emitting device 122, the third laser emitting device 123, and the fourth laser emitting device 124 are used to form the four sides of the pasting position 22. At this time, the pasting position 22 can be a rectangle or any other arbitrary polygon, without specific restrictions.

[0037] Of course, the laser beams emitted by the first laser emitting device 121, the second laser emitting device 122, the third laser emitting device 123, and the fourth laser emitting device 124 can also form two corner points. For example, in Figure 1 Two corner points A and B are formed. It should be understood that when forming two corner points, they can be two corner points of any shape at the pasting position 22. At this time, the first laser emitting device 121 and the second laser emitting device 122 work together to form one corner point, and the third laser emitting device 123 and the fourth laser emitting device 124 work together to form another corner point.

[0038] Regarding the specific configuration of the laser emitting device 12, in some specific embodiments, the laser emitting device 12 includes an adjustment base (not shown) and a laser emitter (not shown). The laser emitter is disposed on the adjustment base, and the adjustment base is used to adjust the position of the laser emitter in order to adjust the laser emission angle of the laser emitter.

[0039] The adjustment base can be fixedly mounted on certain structures. The adjustment mechanism drives the laser emitter to move through its own structure, for example, driving the laser emitter to move in the horizontal and vertical directions, thereby adjusting the emission angle of the laser emitter. When the emission angle of the laser emitter is different, the laser beam emitted by the laser emitter will be projected onto different positions of the outer cover 21, thereby forming different corner points or edge lines to meet the requirements of corner point and edge line formation at different adhesive positions 22.

[0040] To achieve further adjustment of the laser emission angle, combined with Figure 1 In some specific embodiments, the film bonding system 10 for the vehicle exterior covering also includes an adjustment bracket 13, which is disposed around the positioning fixture, and a laser emitting device 12 is disposed on the top of the adjustment bracket 13. The adjustment bracket 13 adjusts the height of the laser emitting device 12 by adjusting its own height.

[0041] It should be understood that when adjusting the height of the laser emitting device 12, the adjusting bracket 13 can adjust the emission angle of the laser emitting device 12, thereby adapting to the needs of more pasting positions 22 for corner and edge formation. Figure 1 In this configuration, the first laser emitting device 121 and the second laser emitting device 122 are integrated and mounted on the adjusting bracket 13, and the third laser emitting device 123 and the fourth laser emitting device 124 are integrated and mounted on the adjusting bracket 13. In other application scenarios, only one laser emitting device can be mounted on an adjusting bracket 13, for example, only the first laser emitting device 121 can be mounted.

[0042] To adapt to use in low-light environments, in some specific embodiments, the film bonding system 10 for the vehicle exterior cover also includes a detection device and an illumination device connected to a control device. The detection device detects the ambient brightness, and the control device controls the illumination device to emit light to illuminate the exterior cover 21 when the brightness is lower than a preset level. The detection device can be a light sensor to detect the light intensity, i.e., the ambient brightness. The detection device and illumination device can be integrated with the image acquisition device 11 to provide better illumination of the exterior cover 21.

[0043] In some specific embodiments, the film bonding system 10 for the vehicle exterior cover also includes a transport device for transporting the exterior cover 21 onto a positioning fixture and sending a signal indicating completion of transport to a control device after transport is completed. When the transport device sends the signal indicating completion of transport to the control device, that is, when the exterior cover 21 is in a specific position, the control device can further control the laser emitting device 12 to emit a laser.

[0044] Specifically, the image acquisition device 11 can be mounted on the conveying device. The image acquisition device 11 is used to acquire feature information of the outer cover 21 to determine the type of the outer cover 21 through the feature information. The feature information can be image feature information of the perforations on the outer cover 21, specifically the shape and position of the perforations. Since different types of outer cover 21 generally have different perforation shapes and positions, the type of the outer cover 21 can be determined by the shape and position of the perforations.

[0045] In this embodiment, images of the outer cover 21 can be acquired before or during the handling process to obtain feature information. In some embodiments, images of the entire outer cover 21 can be acquired, while in others, images of specific perforations can be acquired, depending on the specific application scenario.

[0046] In some specific embodiments, the transport device is further configured with a main body and a gripping arm. The gripping arm is movable relative to the main body, and an image acquisition device 11 is mounted on the gripping arm. The gripping arm is used to grip the outer cover 21 for transporting the outer cover 21. In this case, the transport device can be a transport robot, which transports the outer cover 21 by moving the gripping arm. Mounting the image acquisition device 11 on the gripping arm facilitates image acquisition of the outer cover 21.

[0047] Furthermore, in some specific embodiments, the film pasting system 10 for the vehicle exterior covering also includes an alarm device connected to the control device; wherein, after the reinforcing film is pasted, the image acquisition device 11 acquires an image of the film pasting position 22, and the control device processes the image to determine that when the error between the position of the reinforcing film and the pasting position 22 exceeds a preset error, it controls the alarm device to sound an alarm.

[0048] It should be understood that even with the corners and / or edges of the pasting position 22, the reinforcing film may still be pasted inaccurately. In this case, if the error between the position of the reinforcing film obtained from image processing by the control device and the pasting position 22 exceeds a preset error, the control alarm device will sound an alarm, allowing the user to be aware of the inaccuracy and make corrections to ensure the accuracy of the pasting position 22.

[0049] In summary, the film bonding system 10 for vehicle exterior panels provided in this application includes: an image acquisition device 11 for acquiring an image of the exterior panel 21; a laser emitting device 12 for emitting a laser beam toward the exterior panel 21 so that the laser beam is projected onto the exterior panel 21; and a control device connected to the image acquisition device 11 and the laser emitting device 12. The control device receives and processes the image to determine the type of the exterior panel 21, determines the bonding position 22 of the reinforcing film on the surface of the exterior panel 21 according to the type, and controls the laser emitting device 12 to emit a laser beam to form the corner points and / or edges of the bonding position 22. Therefore, by forming the corner points and / or edges of the bonding position 22 using the laser emitting device 12, the reinforcing film can be bonded according to the corner points and edges, improving the bonding accuracy and product quality.
