Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, specifically to a polarizer laser processing mechanism. Background Technology

[0002] Polarizing films, as optical materials, are widely used in displays, cameras, optical instruments, and other fields. Their processing precision and efficiency directly affect the performance and quality of the final product. Traditional polarizing film processing technologies mainly rely on methods such as mechanical cutting and chemical etching, which have some significant drawbacks. For example, mechanical cutting easily leads to edge damage of the material, affecting optical performance; while chemical etching requires the use of large amounts of chemical reagents, posing environmental pollution and safety hazards. Furthermore, existing technologies are also insufficient in processing efficiency, typically requiring long processing times, which cannot meet the needs of large-scale production.

[0003] With the development of laser technology, laser cutting has gradually become the mainstream technology for polarizer processing due to its advantages such as high precision, non-contact processing, and strong adaptability. However, traditional polarizer laser cutting and processing are carried out sequentially with the loading and unloading process, resulting in high equipment idle rates and limited production capacity. Summary of the Invention

The first transfer pickup module is used to pick up workpieces to be processed from the outside and place them on the first or second processing platform, and to pick up workpieces processed on the first or second processing platform and place them to the outside. The first platform traverse drive module is used to drive the first processing platform to reciprocate between the first laser cutting device and the first transfer pickup module, and the second platform traverse drive module is used to drive the second processing platform to reciprocate between the second laser cutting device and the first transfer pickup module. The first laser cutting device is used to cut workpieces placed on the first processing platform, and the second laser cutting device is used to cut workpieces placed on the second processing platform.

[0007] Wherein, the conveying direction of the first platform lateral movement drive module is parallel to the conveying direction of the second platform lateral movement drive module, and the conveying direction of the first transfer pickup module intersects perpendicularly with the conveying direction of the first platform lateral movement drive module.

The first picking lifting drive mechanism is used to drive the first picking assembly to lift, and the second picking lifting drive mechanism is used to drive the second picking assembly to lift. Both the first picking assembly and the second picking assembly are used to pick up workpieces.

[0010] The polarizer laser processing mechanism further includes a third processing platform for placing workpieces, a fourth processing platform for placing workpieces, and a second transfer pickup module located on the other side of the first laser cutting device and the second laser cutting device.

[0015] This invention discloses a polarizer laser processing mechanism that significantly improves processing efficiency and automation by introducing a dual-platform design and a transfer and pickup module. Specifically, the parallel operation of the first and second laser cutting devices allows the two processing platforms to alternate processing, avoiding the time wasted between processing and handling in traditional single-platform systems. Furthermore, the design of the first transfer and pickup module makes the workpiece handling process more efficient, enabling rapid placement of the workpiece on the processing platform and quick removal after processing, reducing the possibility of manual intervention and operational errors.

[0028] Polarizing films, as optical materials, are widely used in displays, cameras, optical instruments, and other fields. Their processing precision and efficiency directly affect the performance and quality of the final product. Traditional polarizing film processing technologies mainly rely on methods such as mechanical cutting and chemical etching, which have some significant drawbacks. For example, mechanical cutting easily leads to edge damage of the material, affecting optical performance; while chemical etching requires the use of large amounts of chemical reagents, posing environmental pollution and safety hazards. Furthermore, existing technologies are also insufficient in processing efficiency, typically requiring long processing times, which cannot meet the needs of large-scale production.

[0029] With the development of laser technology, laser cutting has gradually become the mainstream technology for polarizer processing due to its advantages such as high precision, non-contact processing, and strong adaptability. However, traditional polarizer laser cutting and processing are carried out sequentially with the loading and unloading process, resulting in high equipment idle rates and limited production capacity.

[0030] To address the aforementioned problems, this embodiment discloses a polarizer laser processing mechanism, the structure of which is as follows: Figures 1 to 3As shown, the polarizer laser processing mechanism includes a first laser cutting device 100, a second laser cutting device 101, a first platform lateral movement drive module 201, a second platform lateral movement drive module 202, a first transfer pickup module 300 located on one side of the first laser cutting device 100 and the second laser cutting device 101, a first processing platform 102 for placing workpieces, and a second processing platform 103 for placing workpieces; the first transfer pickup module 300 is used to pick up external workpieces to be processed and place them on the first processing platform 102 or the second processing platform 103, and to transfer the workpieces from the first processing platform 102 or the second processing platform 103 to the second processing platform 103. The workpiece processed on platform 03 is picked up and placed in the outside; the first platform lateral drive module 201 is used to drive the first processing platform 102 to reciprocate between the first laser cutting device 100 and the first transfer and pick-up module 300, and the second platform lateral drive module 202 is used to drive the second processing platform 103 to reciprocate between the second laser cutting device 101 and the first transfer and pick-up module 300; the first laser cutting device 100 is used to cut the workpiece placed on the first processing platform 102, and the second laser cutting device 101 is used to cut the workpiece placed on the second processing platform 103.

[0031] Specifically, the polarizer laser processing mechanism of this invention significantly improves processing efficiency and automation by introducing a dual-platform design and a transfer and pickup module. Specifically, the parallel operation of the first laser cutting device 100 and the second laser cutting device 101 allows the two processing platforms to process alternately, avoiding the time wasted between processing and handling in traditional single-platform systems. Furthermore, the design of the first transfer and pickup module 300 makes the workpiece handling process more efficient, enabling rapid placement of the workpiece on the processing platform and quick removal after processing, reducing the possibility of manual intervention and operational errors.

[0032] Through this structural optimization, this embodiment not only improves the processing efficiency of polarizers, but also ensures high precision and consistency during the processing, meeting the needs of modern industry for high-quality optical materials.

The first picking lifting drive mechanism 302 is used to drive the first picking assembly 304 to lift, and the second picking lifting drive mechanism 303 is used to drive the second picking assembly 305 to lift.

Among them, the first processing platform 102 and the third processing platform 104 are located on both sides of the first laser cutting device 100, and the second processing platform 103 and the fourth processing platform 105 are located on both sides of the first laser cutting device 100. The system can automatically select to control the first transfer pickup module 300 or the second transfer pickup module 106 to pick up and place the workpiece according to the current working status of the processing platform and the laser cutting device, thereby further improving processing efficiency.

[0039] Preferably, both the first platform transverse drive module 201 and the first platform transverse drive module 201 are linear motors with dual output ends.
