Description

Technical Field

[0001] This utility model relates to dispensing equipment, specifically to a dispensing equipment for filling curved surfaces of 3D printed screen borders. Background Technology

[0002] In the production process of 3D printed screen bezels, the dispensing of adhesive on the curved surface of the bezel filling is a key step. The dispensing accuracy, efficiency, and adhesive curing effect directly affect the quality of the screen and the production efficiency.

[0003] Currently, existing dispensing equipment has many shortcomings: traditional dispensing equipment is mostly designed for planar dispensing, lacking the ability to accurately identify and dynamically adapt to curved surfaces. When faced with the complex curved surface structure of 3D printed screen edges, it is difficult to control the uniform distribution of adhesive, and problems such as local overflow and insufficient adhesive are prone to occur. The mechanical structure and motion control algorithm of the equipment are not optimized for curved surface operations, which makes it impossible to keep the distance between the dispensing head and the curved surface constant. This not only affects the consistency and accuracy of dispensing, but also makes the product easily damaged by collision.

[0004] In addition, the existing equipment has a low degree of automation, often requiring manual assistance for alignment and adjustment, which not only increases labor costs but also makes it difficult to guarantee the consistency and accuracy of dispensing; it has poor adaptability to 3D printed screen frames of different specifications and shapes, and requires a lot of time for equipment debugging when changing products; the glue does not cure in time after dispensing, which can easily lead to problems such as glue running and deformation, affecting the dispensing quality; and the overall production efficiency is not high, which cannot meet the needs of large-scale production.

[0005] Therefore, there is an urgent need for a 3D printing screen bezel filling curved surface dispensing device that can achieve automated, high-precision, and high-efficiency dispensing and is highly adaptable. Utility Model Content

[0036] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] Example 1: The specific structure of this utility model is as follows:

[0038] Please refer to the appendix. Figure 1-3 The present invention relates to a 3D printing screen frame filling curved surface dispensing device, comprising a gantry frame 8, multiple X-axis drive mechanisms 9, multiple Z-axis drive mechanisms 11, a dispensing mechanism, an adhesive curing device 18, and multiple Y-axis drive mechanisms 10.

[0039] The gantry 8 serves as the overall support structure for the equipment and is fixed to a single plate.

[0040] Multiple sets of X-axis drive mechanisms 9 are installed on the gantry frame 8 and are arranged along the X-axis. In this embodiment, the X-axis drive mechanism 9 adopts an X-axis linear motor. Each set of X-axis drive mechanism 9 is driven and connected to an X-axis connecting part. The X-axis drive mechanism 9 drives the X-axis connecting part to move along the X-axis, thereby realizing the position adjustment of the dispensing mechanism in the X direction.

[0041] Multiple Z-axis drive mechanisms 11 are installed one-to-one on the X-axis connection part. The power source of the Z-axis drive mechanism 11 is a Z-axis motor. The Z-axis motor drives the Z-axis lead screw. The Z-axis lead screw is screwed with a nut. The nut is fixed to the Z-axis connection part. The Z-axis drive mechanism 11 drives the Z-axis connection part to move in the Z-axis direction, which drives the dispensing mechanism to move up and down to adjust the dispensing height.

[0042] The dispensing mechanism is mounted along the Z-axis of the Z-axis connection and includes a height measuring module 14, a camera vision alignment module 15, and a dispensing device 16 arranged from left to right. The height measuring module 14 measures the height of the workpiece, providing a basis for adjusting the Z-axis position of the dispensing device 16; the camera vision alignment module 15 captures an image of the workpiece to align it with a preset pattern and determine the dispensing position; the dispensing device 16 performs the dispensing operation based on the alignment result.

[0043] The glue curing device 18 is mounted on the side of the gantry 8 with the curing direction facing downward. The X-axis connecting part has a clearance space that allows the glue curing device 18 to pass through, so as to avoid interference between the X-axis connecting part and the glue curing device 18 when the X-axis connecting part moves.

[0044] Multiple sets of Y-axis drive mechanisms 10 are arranged one-to-one below the glue curing device 18. The Y-axis drive mechanism 10 adopts a Y-axis linear motor, which is driven by a Y-axis connecting part. The path of the Y-axis connecting part after being driven can pass directly below the glue curing device 18, so as to drive the workpiece to the curing position for glue curing.

[0045] The AC axis drive mechanism 12 is installed at the Y axis connection. The AC axis drive mechanism 12 drives the material platform 13 to perform rotational movements along the A axis and C axis. The rotational plane along the A axis is perpendicular to the Y axis, and the rotational plane along the C axis is perpendicular to the rotational plane along the A axis, thereby adjusting the posture of the material platform 13 for precise dispensing.

[0049] A rotatable support bracket 123 mounted on the U-shaped opening;

[0050] A C-axis motor 124 is vertically fixed to the support bracket 123, and the C-axis motor 124 drives the material loading platform 13.

[0051] The loading surface of the loading platform 13 is provided with negative pressure holes, and the workpiece is adsorbed onto the loading platform 13 by negative pressure.

[0052] The Y-axis drive mechanism 10 is provided with a glue-wiping device 17 on its adjacent side, which is used to clean the glue residue on the loading platform 13.

[0053] Example 2:

[0054] The working process of this equipment is as follows: the 3D printed screen frame workpiece is placed on the loading platform 13 and fixed through the negative pressure hole.

[0055] The Y-axis drive mechanism 10 moves the Y-axis connecting part, the AC-axis drive mechanism 12, and the material loading platform 13 to below the dispensing mechanism. The X-axis drive mechanism 9 and the Z-axis drive mechanism 11 adjust the position of the dispensing mechanism, the height measurement module 14 measures the workpiece height, and the camera vision alignment module 15 performs alignment.

[0056] AC axis drive mechanism 12 adjusts the workpiece posture according to the alignment result, and dispensing device 16 performs dispensing.

[0057] After the glue is applied, the Y-axis drive mechanism 10 moves the workpiece directly below the glue curing device 18 for curing.

[0058] Meanwhile, the material loading platform 13 can be moved to the adhesive application device 17 for cleaning. Multiple drive mechanisms can simultaneously perform adhesive application and curing operations on multiple workpieces, improving production efficiency.

[0059] In summary, the curved surface dispensing equipment of this utility model can automate curved surface dispensing: through the coordinated work of multiple sets of drive mechanisms, height measurement modules, camera vision alignment modules, etc., it can achieve fully automated operation from workpiece curved surface positioning, curved surface dispensing to glue curing for the curved surface of 3D printed screen frame, reducing manual intervention and lowering labor costs.

[0060] This utility model of curved surface dispensing equipment enables high-precision dispensing of adhesive to curved workpieces: the height measurement module accurately measures the height of the curved workpiece, the camera vision alignment module completes the precise alignment of the curved surface, the AC axis drive mechanism flexibly adjusts the posture of the workpiece curved surface, and the multi-axis drive mechanism ensures the motion accuracy of the dispensing mechanism on the curved surface, thus ensuring high precision of curved surface dispensing.

[0061] This utility model of curved surface dispensing equipment enables efficient dispensing production: multiple drive mechanisms can process multiple curved surface workpieces simultaneously, and the glue is cured in time after dispensing, which greatly shortens the production cycle of dispensing on the curved surface of 3D printed screen frame and improves production efficiency.

[0062] The curved surface dispensing equipment of this utility model has strong adaptability to curved surface dispensing: it can adapt to the curved surface dispensing needs of 3D printed screen frames of different specifications and shapes by adjusting each drive mechanism and AC axis drive mechanism, thereby reducing equipment debugging time.
