Detailed Implementation

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] like Figure 1-6 As shown, the embodiments of this utility model include: A corner-applying film device includes a rotary table 1, corner fixtures 2, a first suction head 3, a second suction head 4, an XY-axis linear module 5, and an XYZ-axis linear module 6. The rotary table 1 is equipped with several corner fixtures 2. First suction heads 3 and second suction heads 4 are sequentially arranged around the rotary table 1 to engage with each corner fixture 2. The first suction head 3 is mounted on a Z-axis servo screw slide 7, which is suspended from the XY-axis linear module 5. The second suction head 4 is mounted under a θ-axis servo motor 8, which is mounted via a swing arm under a 90-degree rotation servo 9. The 90-degree rotation servo 9 is suspended from the XYZ-axis linear module 6. Each corner fixture 2 includes a horizontal section 10 and a vertical section 11. The first suction head 3 engages with the horizontal section 10, and the second suction head 4 engages with the vertical section 11.

[0016] The corner fitting 2 includes a carrier 12 and a rotary clamping cylinder 13. The carrier 12 has corner limiting blocks 14 at both ends and a positioning groove between the corner limiting blocks 14. The rotary clamping cylinder 13 is fitted into the positioning groove. The rotary clamping cylinder 13 has a swinging pressing block 15. A calibration plate 16 is provided on the top of the swinging pressing block 15. A side vision positioning camera 17 is provided next to the corner fitting 2, facing the calibration plate 16. The calibration plate 16 is used for positioning correction and type change recognition.

[0017] Furthermore, the first suction head 3 is used to apply film to the horizontal section 10 of the inside corner, and the second suction head 4 is used to apply film to the vertical section 11 of the inside corner. The first suction head 3 is connected to a first feeder 18 through the XY two-axis linear module 5, and the second suction head 4 is connected to a second feeder 19 through the XYZ three-axis linear module 6.

[0018] Furthermore, the first feeder 18 and the second feeder 19 are each equipped with a downward vision positioning camera 20.

[0019] Furthermore, both the first suction head 3 and the second suction head 4 are equipped with a first exhaust scraper 21 next to the corner fixture 2. The first exhaust scraper 21 is suspended on a Z-axis cylinder 22, which is mounted on an X-axis telescopic cylinder 23. The X-axis telescopic cylinder 23 is horizontally suspended on a Y-axis slide cylinder 24. The first exhaust scraper 21 is used to apply film to the horizontal section 10 of the corner.

[0020] Furthermore, a second exhaust scraper 25 is arranged on the periphery of the rotary table 1 downstream of the first suction head 3 and the second suction head 4. The second exhaust scraper 25 is sequentially mounted on the Z-axis slide cylinder 28 via the horizontal gripper cylinder 26 and the lifting cylinder 27. The second exhaust scraper 25 is used to apply film to the vertical section 11 of the inside corner.

[0021] Furthermore, the second feeder 19 has an extended feed table 29, at the end of which a peeling knife is provided. A shaping groove is formed on the surface of the extended feed table 29 along the unwinding direction. A folding pressure roller 30 embedded in the shaping groove is mounted directly above the groove. The folding pressure roller 30 is used to fold the film edge and make the folded edge cover the center seam of the inside corner.

[0022] Furthermore, the Z-axis servo screw slide 7 is mounted on a backplate bracket 31. The backplate bracket 31 is provided with an extension section, and an upper bearing 32 is installed on the extension section. A bracket 33 is installed on the Z-axis servo screw slide 7, and a lower bearing 34 is provided on the bracket 33. The upper bearing 32 and the lower bearing 34 are coaxially connected to the Z-axis rotating shaft 35. The first suction head 3 is located at the lower end of the Z-axis rotating shaft 35. A servo synchronous pulley set 36 is externally connected to the upper bearing. The servo synchronous pulley set 36 is used to cooperate with the lower vision positioning camera 20 to adjust the film application angle.

[0023] like Figure 1 As shown, the workpiece is first placed in the corner fixture 2, and then the rotary table 1 rotates clockwise by one station. At this time, the first feeder 18 delivers a horizontal section of film, which is picked up by the first suction head 3 driven by the XY two-axis linear module 5. Then it is placed in the lower vision positioning camera 20 for position correction, and then transported to the film application position on the left end of the corner fixture 2 (each end of the lower vision positioning camera 20 has a corner film application point), which is the horizontal section.

[0024] Next, the rotary table 11 rotates one station, and the first feeder 18 delivers a horizontal section of film. The XY-axis linear module 5 drives the first suction head 3 to pick up the film, then places it in the lower vision positioning camera 20 for calibration, and then moves it to the right end of the corner fixture 2 for application. Simultaneously with film application, as... Figure 2 The first exhaust scraper 21 shown is driven by the Z-axis cylinder 22, the X-axis telescopic cylinder 23, and the Y-axis slide cylinder 24 to exhaust air to the left end of the corner fixture 2.

[0025] The next step is to rotate the rotary table 1 one station to apply the film to the vertical section, such as... Figure 4 The XYZ three-axis linear module 6 drives the second suction head 4 to pick up the material from the second feeder 19. The second feeder 19 delivers a piece of film in a vertical section, places it on the lower vision positioning camera 20 for calibration, and then the θ axis servo motor 8 corrects the angle deviation. Then, the 90-degree flip servo 9 flips the film by 90 degrees to make it vertical, and then moves it to the left end of the corner fixture 2 to be applied to the vertical section.

[0026] Then, the rotary table 1 rotates one station to apply the film to the vertical section of the other end of the corner fitting 2. Similarly, after material handling, correction, and flipping, the film is applied. After film application, the rotary table 1 continues to rotate one station to reach the desired position. Figure 5 Air is released from the vertical section of the film at the indicated location. This completes the entire process.

[0027] To solve the problem of incomplete film application at the corner seams, such as Figure 4 The added folding roller 30 is used to fold the edge, and the folded edge covers the center seam of the inside corner and overlaps the film on the horizontal section to achieve full coverage.

[0028] To address the positioning issues after changing the shape of different workpieces, a calibration plate 16 is added to each swing block 15 to identify the process execution plan. Furthermore, defect detection and identification are performed after film application and venting are completed, thereby ensuring the quality of film application.

[0029] In summary, this utility model provides a corner film application device that uses a suction head to pick up materials and apply film, and uses an exhaust scraper to simultaneously perform exhaust treatment. At the same time, the film is applied by a folding pressure roller to achieve full coverage of the corner seam, thereby realizing automated film application processing, improving film application yield, and increasing workpiece coating efficiency.
