Description

Technical Field

[0001] This utility model relates to the field of laser engraving technology, specifically to a flexible resin digital laser engraving machine. Background Technology

[0002] In the field of laser engraving technology, flexible resin plates are widely used in industries requiring high precision, such as packaging printing and label making, due to their excellent flexibility and ease of shaping. The precision and efficiency of their engraving process directly determine the clarity, detail, and overall quality of the final printed product.

[0003] Currently, most mainstream flexible resin plate laser engraving equipment on the market uses a fixed-angle laser emitter head, generally set vertically downwards, and paired with a conventional three-axis linear motion platform. This structural design determines that the processing direction of the laser beam is relatively singular. Although it can handle planar engraving tasks, it becomes severely inflexible when dealing with workpieces with complex three-dimensional curved surfaces, specific tilt angle textures, or workpieces requiring multi-directional collaborative processing.

[0004] The equipment cannot dynamically adjust the incident angle of the laser, which can easily lead to uneven energy distribution, inconsistent carving depth, and even loss of local details when carving non-planar areas, making it difficult to meet the growing demand for multi-directional and multi-angle fine carving. Utility Model Content

[0005] The purpose of this invention is to provide a flexible resin digital laser engraving machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexible resin digital laser engraving machine, comprising a worktable, the worktable being an existing worktable with negative pressure adsorption function, a gantry frame movably mounted on the worktable along the Y-axis, a lifting frame movably mounted on one side of the top of the gantry frame along the X-axis, a mounting frame movably mounted on the lifting frame along the Z-axis, a mounting base horizontally mounted at the bottom of the mounting frame, a rotating seat horizontally mounted at the bottom of the mounting base via a shaft and bearing, a first rotating motor drivingly connected to the top of the rotating seat, a laser head mounted inside the rotating seat, a rotating frame mounted outside the laser head, the rotating frame rotatably mounted on the rotating seat via a shaft and bearing, a second rotating motor drivingly connected to the drive end of the rotating frame, and a vision positioning camera mounted at the bottom of the gantry frame.

[0007] The present invention is further configured such that a conductive slide rail is provided at one end of the top of the worktable, and a movable slide is provided on the conductive slide rail. One end of the gantry is mounted on the movable slide. Here, the conductive slide rail is driven by a servo motor or by electromagnetic drive. The operation of the conductive slide rail by the servo motor or by electromagnetic drive enables the movable slide to drive the gantry to move along the Y-axis on the worktable, thereby controlling the flexible adjustment of the working position of the laser head in the Y-axis direction.

[0008] The present invention is further configured such that a linear slide rail is provided on one side of the workbench, and a sliding seat is provided on the linear slide rail. The other end of the gantry frame is installed on the sliding seat. The cooperation between the linear slide rail and the sliding seat is used to assist in the stable support of the gantry frame on the workbench.

[0009] The present invention is further configured such that a first ball screw is provided on one side of the top of the gantry frame, a first screw motor is connected to the drive end of the first ball screw, a first screw nut is provided on the first ball screw, and the lifting frame is vertically mounted on the first screw nut. The operation of the first ball screw is controlled by the first screw motor, so that the first screw nut can drive the lifting frame to move along the X-axis on one side of the top of the gantry frame, thereby realizing flexible adjustment of the working position of the laser head in the X-axis direction.

[0010] The present invention is further configured such that a second ball screw is vertically mounted on the lifting frame, a second screw motor is connected to the driving end of the second ball screw, a second screw nut is fitted on the second ball screw, and the mounting frame is mounted on the second screw nut. When the second screw motor is started, the operation of the second ball screw is controlled, so that the second screw nut can drive the mounting frame to achieve lifting and adjustment, thereby realizing the lifting and adjustment of the laser head during operation and realizing flexible adjustment of the working distance between the laser head and the flexible resin plate.

[0011] The present invention is further configured such that two clamping frames are symmetrically sleeved on the worktable, the clamping frames are U-shaped and slidably sleeved on the worktable, and the bottom end of the worktable is provided with a synchronous opposing drive structure and a lifting structure corresponding to the clamping frames.

[0012] The present invention is further configured such that the synchronous opposing drive structure includes a bidirectional ball screw, the drive end of which is connected to a third screw motor. Two sets of third screw nuts are symmetrically arranged on the bidirectional ball screw, and the clamping frame is respectively installed on the corresponding third screw nuts. In use, the third screw motor can be started to control the operation of the bidirectional ball screw, so that the two sets of third screw nuts can drive the clamping frame to move closer or further apart. This allows for flexible adjustment of the clamping position of the clamping frame according to the width of the flexible resin plate, improving the operational stability of the flexible resin plate during laser engraving. In addition, the clamping frame in this invention is sleeved on the worktable and can be adapted to the clamping operation of flexible resin plates of any length within the worktable range.

[0013] The present invention is further configured such that the lifting structure includes a bottom fixed seat, a lifting electric cylinder is provided on the bottom fixed seat, a lifting seat is provided at the top of the lifting electric cylinder, a bidirectional ball screw is installed on the lifting seat, a fixed column is provided at the corner of the bottom fixed seat, a lifting column is slidably installed on the upper limit of the fixed column, and the top of the lifting column is connected to the bottom of the lifting seat. After the clamping frame is adjusted to a suitable position, the lifting electric cylinder is activated, and the lifting seat is lowered by controlling the lifting electric cylinder, so that the lifting seat drives the bidirectional ball screw and the third screw nut to lower, thereby controlling the clamping frame to lower through the third screw nut. The clamping frame clamps and fixes the flexible resin plate on the worktable to ensure stability during laser engraving. The present invention can provide flexible clamping pads, such as rubber pads, silicone pads, etc., on the side of the clamping frame near the worktable and on the opposite side of the two sets of clamping frames. In this way, while ensuring that the clamping frame clamps and fixes the flexible resin plate, damage to the flexible resin plate is avoided.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Precise positioning and flexible engraving with multiple degrees of freedom. This invention utilizes a conductive slide rail and a movable slide table to drive the gantry frame to move along the Y-axis, combined with a first ball screw controlling the lifting frame to move along the X-axis, and a second ball screw realizing the Z-axis lifting and lowering of the mounting frame, forming a three-dimensional precision positioning system. The laser head is controlled to rotate horizontally by a first rotary motor, and a second rotary motor drives the rotating frame to adjust its vertical angle, enabling multi-directional and multi-angle engraving of flexible resin plates. A visual positioning camera assists in precise positioning, ensuring high-precision engraving of complex patterns and significantly improving operational flexibility and applicability.

[0015] 2. Adaptive clamping structure enhances operational stability. The worktable features symmetrically arranged U-shaped clamping frames, which move synchronously in opposite directions via a bidirectional ball screw and a third lead screw motor, accommodating flexible resin plates of varying widths. A lifting electric cylinder drives the clamping frames to descend, working in conjunction with flexible clamping pads (such as rubber pads) to firmly secure the plate, preventing displacement or vibration during engraving. This structure is compatible with the full range of worktable sizes, ensuring engraving stability while preventing damage to the resin plate surface, significantly improving processing quality and equipment applicability.

[0016] 3. Integrated driving force and efficient collaborative control The equipment integrates multiple motors and lead screw structures, coordinating the movement of each axis through electrical systems. The laser head angle and position can be dynamically adjusted to adapt to curved or tilted engraving needs. The negative pressure adsorption worktable and clamping mechanism work together to ensure the board is flat and fixed. The vision system provides real-time feedback of positioning data, forming a closed-loop control that improves engraving efficiency and consistency. The overall design is compact and easy to operate, suitable for high-precision, high-efficiency digital laser processing of flexible resin plates. Attached Figure Description
