Description

Technical Field

[0001] The present invention relates to the field of alignment film printing in the liquid crystal panel display industry. More specifically, the present invention relates to an auxiliary tooling, a laser engraving machine and a method of using the same that can be used for laser engraving platemaking. Background Art

[0002] With the improvement of people's scientific and technological level and the enrichment of material life, the LCD panel industry is developing faster and faster, and flexible printing technology is widely used. In this printing technology, flexible resin plates are used for printing and plate making. Printing plates are photosensitive resin materials. The patterns to be printed are engraved by laser. The laser engraving graphics are set according to the customer's drawings. The plate sizes, thicknesses, and engraving surfaces of different clients are inconsistent, so they can only be processed independently. However, the drum circumference of the laser engraving machine is relatively long, and the laser light engraving consumes the same time and laser power for one circle. With the continuous investment of panel manufacturers in 8.5-generation capacity and LTPS capacity, the growth rate of the overall capacity of the global display industry has shown an upward trend year by year. With the increasing orders and the shortage of NSC plate capacity, in order to maximize the use of equipment to improve plate making efficiency and shorten customer delivery time, a bold idea is proposed based on the original plate making method. The same laser engraving equipment is used to process NSC resin plates of different sizes at the same time, which ensures the accuracy of plate making and meets the shipping standards. Summary of the invention

[0003] The purpose of the present invention is to provide an auxiliary tooling and a method of use that can be used for laser engraving and platemaking processing, so as to solve the problem of difficult positioning accuracy during laser engraving and platemaking processing of resin printing plates of different sizes. This method has extremely high positioning accuracy and can not only perfectly engrave the processing drawing, but also avoid defects in the resin plate surface. It is of great help to the company's production capacity improvement, and can also shorten the delivery time and enhance product competitiveness and customer satisfaction.

[0004] The technical solution adopted by the present invention to solve this technical problem is: an auxiliary tooling that can be used for laser engraving platemaking processing, including: an X tooling and a Y tooling;

[0005] The X tooling is horizontally fixed on the plate mounting cylinder of the laser engraving machine and extends along the X-axis direction of the plate mounting cylinder;

[0006] The Y tooling is fixed on the plate mounting cylinder perpendicular to the X tooling.

[0007] The present invention also provides a laser engraving machine with auxiliary tooling, comprising: a plate mounting cylinder, a cylinder coaxial shaft, a laser generator, an X-travel power device and a rotation power device;

[0008] The drum coaxial shaft is mounted on the main frame of the laser engraving machine, and the coaxial shaft is used to fix the plate-mounting drum for laser engraving;

[0009] A laser generator, used to emit laser light of a certain power;

[0010] X-axis travel power device, used to drive the laser generator to travel in the X-axis direction;

[0011] A rotary power device, used to drive the plate mounting cylinder to rotate around its axis;

[0012] The auxiliary tooling is mounted on the plate mounting cylinder.

[0013] The present invention also provides a method for using an auxiliary tooling that can be used for laser engraving platemaking, comprising the following steps:

[0014] S1. Before laser engraving the resin plate, complete the first resin plate;

[0015] S2. Align the Y tooling closely with the left side of the processed resin plate 1, and confirm the fitting condition of the Y tooling and the plate mounting roller according to the normal operation process;

[0016] S3, align the upper left corner of the X tooling with the right angle formed by the processing resin plate 1 and the Y tooling, and align the long side of the X tooling closely with the long side of the processing resin plate 1;

[0017] S4. Place the processed resin plate 2 close to the bottom of the X tooling, and strictly follow the normal operation process to confirm the bonding condition between the processed resin plate 2 and the plate mounting roller;

[0018] S5. Finally, the pre-designed layout is imported into the laser engraving machine for laser engraving.

[0019] As a further solution of the present invention, S1 specifically includes: before laser engraving the resin plate, designing the platemaking drawing according to the size of the processed resin plate and the size of the auxiliary tooling, placing the processed resin plate 1 along the plate mounting drum joint according to the normal plate mounting process, and confirming the bonding condition between the processed resin plate 1 and the plate mounting drum in strict accordance with the normal operation process;

[0020] As a further solution of the present invention, the laser engraving machine comprises: a plate mounting cylinder, a cylinder coaxial shaft, a laser generator, an X-travel power device and a rotation power device.

[0021] As a further solution of the present invention, the step S5 specifically includes:

[0022] S51, the laser spot emitted by the laser generator has a fixed light output position. To carve a surface from a point, the photosensitive resin plate needs to be moved continuously. The X-travel power device provides the laser generator with power to travel in the X direction.

[0023] S52, the rotary power device provides power for the rotation direction of the plate mounting drum. When the laser generator and the laser spot are fixed, the laser engraving process from top to bottom is completed by rotating the plate mounting drum.

[0024] The present invention includes at least the following beneficial effects: In the case of NSC plate production capacity being in short supply, in order to maximize the use of equipment to improve plate-making efficiency and shorten customer delivery time, a bold idea is proposed based on the original plate-making method, using the same laser engraving equipment to simultaneously process NSC resin plates of different sizes, which ensures the accuracy of plate-making and meets the shipping standards. However, the laser engraving process has high requirements for plate-mounting accuracy. The plate must be precisely fitted to the roller of the laser engraving equipment to avoid gaps. When processing multiple plates at the same time, except for the first plate with a reference alignment scale line, the alignment accuracy of the remaining plates is a difficult point. If the alignment accuracy of the remaining plates deviates, then the laser engraved pattern will deviate, and some defects that need to be avoided in the engraving procedure cannot be guaranteed to be completely avoided. The patented platemaking auxiliary tooling and use method of the present invention, assuming that the production of a single plate requires 10 hours, now the platemaking production only needs 10 hours, which is equivalent to saving half of the single-side production time. It can effectively improve the utilization rate of laser engraving equipment and save production hours, and can solve the problem of difficult positioning accuracy during the laser engraving platemaking process of resin printing plates of different sizes. This method has extremely high positioning accuracy and can not only perfectly engrave the processing drawing, but also avoid defects in the resin plate surface. It has greatly helped the company to improve its production capacity, and can also shorten the delivery time and improve product competitiveness and customer satisfaction.
