[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] The embodiment of the utility model provides a quick alignment device for a glue filling head, including a lifting plate 1, the lifting plate 1 is mounted on a Z-axis screw rod module for driving the lifting plate 1 to lift, a slide rail 2 is vertically mounted on one side of the lifting plate 1, a slider 3 is slidably arranged on the slide rail 2, a mounting plate 4 is mounted on one side of the slider 3, a sliding connection is achieved between the mounting plate 4 and the lifting plate 1 through the slider 3 and the slide rail 2, a glue filling module 5 is mounted on one side of the mounting plate 4, a magnetic grating scale group 6 is also mounted between the mounting plate 4 and the lifting plate 1, the magnetic grating scale group 6 includes a magnetic grating scale and a magnetic grating reading head, the magnetic grating scale is mounted on the lifting plate 1, and the magnetic grating reading head is mounted on the mounting plate 4. When aligning, a calibration plate is placed on the top surface of the product, and the calibration plate is calibrated by the Z-axis. The screw module drives the lifting plate 1 to descend, and the lifting plate 1 drives the glue filling module 5 to descend. When the glue filling module 5 descends to contact with the top surface of the calibration plate, the reading of the magnetic scale group 6 will change, and the instantaneous pulse of the servo motor on the Z-axis screw module at this time is recorded. When the reading of the magnetic scale group 5 is equal to the thickness of the calibration plate, it means that the glue filling module 5 reaches the product glue filling position during actual glue filling, and the displacement of the servo motor for each pulse is certain. Therefore, it can be calculated how many pulses the servo motor needs to take after the glue filling module 5 contacts the calibration plate to reach the product's glue filling position. The servo motor pulse when the glue filling module 5 reaches the product glue filling position can be calculated. No manual operation is required, and the positioning accuracy is high.

[0019] In this embodiment, the glue pouring module 5 includes a driving motor 51, which includes a rotary servo motor and a matching reducer. The output shaft of the driving motor 51 is connected to the top of the glue pouring valve group 52. A glue pouring head group 53 is installed at the bottom of the glue pouring valve group 52. A glue pouring head is installed at the bottom of the glue pouring head group 53. The glue pouring head group 53 can be used to pour glue on the product. The glue pouring valve group 52 can control the glue to flow into the glue pouring head group. The driving motor 51 can drive the glue pouring head group 53 to rotate so that the glue pouring head is aligned with the glue pouring position of the product for pouring glue. The glue pouring module 5 also includes an origin sensor 54 for detecting the origin position of the glue pouring head group 53. The origin sensor 54 is a photoelectric sensor.

[0020] In order to reduce the pressure on the glue pouring head on the glue pouring module 5 when it contacts the calibration plate, the top of the mounting plate 4 is connected to the lifting plate 1 by an elastic member 7. The elastic member 7 is a tension spring. The elastic member 7 can reduce part of the pressure on the glue pouring head when it contacts the calibration plate, thereby preventing the glue pouring head from being crushed.

[0021] In this embodiment, a visual camera group 8 is installed on the lifting plate 1. Through the visual camera group 8, a certain fixed edge can be identified as the initial coordinate. At the same time, the edge of the product is scanned and identified and the corresponding coordinates are recorded. Since the origin position of the glue filling head is fixed, the angle that the glue filling head needs to rotate from the origin position to the working position can be calculated based on the coordinates of a certain fixed edge identified by the visual camera group 8 and the coordinates of the scanned and identified product edge. No manual operation is required, and the positioning accuracy is high.

[0022] Specific principle: When aligning, place the calibration plate on the top surface of the product, drive the lifting plate 1 to descend through the Z-axis screw module, and the lifting plate 1 drives the glue filling module 5 to descend. When the glue filling module 5 descends to contact the top surface of the calibration plate, the reading of the magnetic scale group 6 will change, and the instantaneous pulse of the servo motor on the Z-axis screw module at this time is recorded. When the reading of the magnetic scale group 5 is equal to the thickness of the calibration plate, it means that the glue filling module 5 reaches the glue filling position of the product during actual glue filling, and the displacement of the servo motor for each pulse is determined, so the glue filling module can be calculated. After the servo motor contacts the calibration plate, how many pulses does it take for the servo motor to reach the glue filling position of the product? The servo motor pulses when the glue filling module 5 reaches the glue filling position of the product can be calculated; a fixed edge can be identified as the initial coordinate by the visual camera group 8, and the edge of the product can be identified by scanning and recording the corresponding coordinates. Since the origin position of the glue filling head is fixed, the angle that the glue filling head needs to rotate from the origin position to the working position can be calculated according to the coordinates of a fixed edge identified by the visual camera group 8 and the coordinates of the edge of the product identified by scanning.

[0023] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
