Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, specifically to a flexible material laser adaptive processing platform. Background Technology

[0002] With the widespread application of flexible materials in the electronics field, laser processing has become one of the core technologies for cutting, engraving and drilling flexible materials due to its advantages such as non-contact, high precision, high efficiency and good edge quality. Currently, the industry's well-known flexible material laser processing equipment is usually composed of a laser emission module, a motion drive module, a material clamping module and a control system.

[0003] Existing clamping methods are mostly static fixation methods, which cannot accommodate the local stretching or contraction of flexible materials during processing. This can easily cause the material to deviate from the movement trajectory, resulting in dimensional deviations in the processing. Furthermore, since the flexible material itself has no rigid support, it is prone to chattering or wrinkling as it moves with the platform during processing. Especially in high-speed processing scenarios, it is difficult to compensate for and adjust the dynamic deformation of the material. Utility Model Content

[0004] The purpose of this invention is to provide a flexible material laser adaptive processing platform to solve the problems mentioned in the background art, such as the local stretching or shrinkage of flexible materials during processing, which easily causes the material to deviate from the motion trajectory and cause processing size deviation. Furthermore, since the flexible material itself has no rigid support, the material is prone to chatter or wrinkles with the movement of the platform during processing, especially in high-speed processing scenarios, where it is difficult to compensate and adjust the dynamic deformation of the material.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible material laser adaptive processing platform, including a base, which serves as the basic support structure of the processing platform and carries various functional modules. The upper end of the base is provided with an installation groove, and a negative pressure pump group controller is installed in the installation groove. The negative pressure pump group controller is connected to a partitioned vacuum adsorption platform through the pipe of the negative pressure pump. The partitioned vacuum adsorption platform is used for negative pressure adsorption of flexible materials and serves as a flexible material laser cutting platform. A fixing frame is installed on one side of the upper end of the mounting slot of the base in the horizontal direction, and the fixing frame is set below the electric drive slide rod. The electric drive slide rod is installed above the mounting slot of the base in the longitudinal direction through the bracket, and the electric drive slide rod is slidably connected to the platform support. A partitioned vacuum adsorption platform is installed on the upper end of the platform support by bolts. The fixed frame is equipped with electric drive adjusting screws at both ends, and the slide of the electric drive adjusting screw is installed with the mounting bracket. The mounting bracket is equipped with a guide wheel, which slides in the vertical guide rail. The vertical guide rail is vertically installed on the upper end of the fixed frame, and there are two vertical guide rails. The two mounting brackets are equipped with transverse guide rails, which slide in cooperation with the laser head mounting frame through a guide wheel. The laser head mounting frame is equipped with a laser emitter, and the output end of the laser emitter faces the partitioned vacuum adsorption platform.

[0006] The above technical solution utilizes a longitudinal adjustment structure consisting of a base, an electric drive slide bar, and a platform support, along with a three-dimensional laser head adjustment structure consisting of a fixed frame, an electric drive adjustment screw, and a transverse guide rail, combined with the clamping function of a partitioned vacuum adsorption platform.

[0007] Preferably, the negative pressure pump group controller consists of a negative pressure pump group and a controller, and the negative pressure pumps in the negative pressure pump group are respectively connected to the vacuum adsorption zones of different areas of the partitioned vacuum adsorption platform.

[0008] Using the above technical solution, the negative pressure pump is connected to different adsorption zones of the partitioned vacuum adsorption platform, which can provide an independent negative pressure source for each adsorption zone. The negative pressure can be adjusted separately for the local stretching or shrinking areas of flexible materials, avoiding local deformation caused by a single negative pressure and reducing dimensional deviations.

[0009] Preferably, the partitioned vacuum adsorption platform is provided with multiple independently controlled vacuum adsorption zones, each of which is equipped with a vacuum valve and a pressure sensor, and the pressure sensor is electrically connected to the controller of the negative pressure pump group controller.

[0010] By adopting the above technical solution, the independent adsorption zone of the partitioned vacuum adsorption platform is equipped with a vacuum valve and a pressure sensor, and the sensor is connected to a controller, which can detect the adsorption pressure in each zone in real time. The controller can dynamically adjust the opening of the vacuum valve to achieve precise matching of the adsorption force with the local state of the material, effectively suppress the trajectory deviation caused by local deformation, and improve the processing dimensional accuracy.

[0011] Preferably, the two mounting brackets are connected at both ends of the transverse guide rail, and a drive motor is mounted on the surface of one mounting bracket.

[0012] By adopting the above technical solution, two mounting brackets are connected to the transverse guide rail and a drive motor is added. This not only ensures the structural stability of the transverse guide rail, but also provides a stable transverse power source for the laser head, avoiding laser head deviation caused by guide rail wobbling during high-speed processing, and reducing material chatter caused by the movement of the laser head.

[0013] Preferably, the mounting bracket has a bearing component on its back that is compatible with the electric drive adjusting screw.

[0014] By adopting the above technical solution, the bearing component on the back of the mounting bracket is adapted to the electric drive adjustment screw, which can reduce the transmission friction between the screw and the bracket, making the vertical height adjustment of the laser head smoother and more precise, avoiding focusing deviation caused by adjustment jamming, and adapting to the processing needs of flexible materials of different thicknesses.

[0015] Preferably, the output end of the drive motor is connected to the transmission wheel via a transmission belt, and one side of the transmission belt passes through the buckle on the back of the laser head mounting bracket.

[0016] Using the above technical solution, the drive motor is connected to the laser head mounting frame through a transmission belt and transmission wheel, which can transmit stable power, ensure that the lateral movement speed and trajectory of the laser head are precisely controllable, ensure that the movement trajectory is consistent with the processing path, and reduce dimensional deviations.

[0017] Preferably, a second guide wheel is mounted on the back of the laser head mounting bracket, and the second guide wheel is adapted to the track of the transverse guide slide rail.

[0018] Using the above technical solution, the guide wheel of the laser head mounting bracket is adapted to the transverse guide rail, which can assist the laser head to slide smoothly, reduce shaking and friction during sliding, avoid laser head jitter causing material wrinkles during high-speed processing, and improve processing stability.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This flexible material laser adaptive processing platform: 1. By combining the multiple independent adsorption zones of the partitioned vacuum adsorption platform with the synergistic effect of the negative pressure pump group controller, an effective solution is achieved. The negative pressure pump group controller consists of a negative pressure pump group and a controller. The negative pressure pump supplies pressure to different adsorption zones of the partitioned vacuum adsorption platform, and each adsorption zone is equipped with a vacuum valve and a pressure sensor and is electrically connected to the controller. During processing, the pressure sensor captures the local adsorption pressure changes in real time, and the controller dynamically adjusts the opening of the corresponding vacuum valve and the pressure supplied by the negative pressure pump based on the feedback. This reduces the adaptability of the adsorption force in the local stretching area and increases the adaptability of the adsorption force in the shrinking area. From a structural perspective, this avoids material displacement due to local deformation and significantly reduces processing dimensional deviations. 2. The platform support is slidably connected to the electric drive slide rod, ensuring the stability of the partitioned vacuum adsorption platform during longitudinal movement. The bearing on the back of the mounting bracket is adapted to the electric drive adjusting screw, and its surface guide wheel one is embedded in the vertical guide slide rail. The laser head mounting bracket's back guide wheel two is adapted to the horizontal guide slide rail. The rigid guiding structure of multiple sets of slide rails and guide wheels can absorb the impact kinetic energy during the movement of the platform and laser head, reducing the chatter of the material caused by the movement. At the same time, the stable transmission of the electric drive slide rod prevents the material from wrinkling due to uneven platform movement, providing a stable processing environment for flexible materials without rigid support. 3. A drive motor on a mounting bracket, via a transmission belt and a transmission wheel, drives the laser head mounting bracket to slide precisely along a transverse guide rail. Combined with the longitudinal movement of the platform driven by an electric drive slide bar and the vertical height adjustment of the laser head driven by an electric drive adjusting screw, a three-dimensional dynamic adjustment system is formed. When the material undergoes dynamic deformation due to movement during high-speed processing, the adaptive adsorption of the partitioned vacuum adsorption platform first stabilizes the basic posture of the material. Then, the three-dimensional adjustment system quickly corrects the relative position of the laser head and the material through precise transmission, realizing real-time compensation for dynamic deformation and ensuring processing accuracy and stability under high-speed processing.
