Description

TECHNICAL FIELD

[0001] The application relates to the technical field of film cloth cutting and transferring, and in particular to a PET film cloth high-precision laser cutting and transferring equipment. BACKGROUND

[0002] In high-tech industries such as flexible electronics and new energy batteries, the processing precision and efficiency of PET film cloth as a core functional material directly determine the performance of the terminal product. However, the current film cloth cutting and transferring process still has significant technical bottlenecks. For example, the invention patent with the announcement number CN118768762A: a nylon decorative cloth laser cutting device with automatic feeding, although it realizes automatic feeding by setting a feeding mechanism and flattens the nylon decorative cloth body before entering the laser cutting area, but its structure still has the following problems when applied to the PET film cloth cutting process:

[0003] 1. Low cutting efficiency

[0004] The device adopts a single station cutting mode, and only one film cloth can be divided into two pieces at a time, which cannot realize synchronous cutting of multiple pieces. This low-efficiency cutting leads to a serious shortage of production capacity, which is difficult to meet the high throughput demand of the downstream process for film cloth.

[0005] 2. Lack of tension control

[0006] After the film cloth is cut into two pieces by the laser cutting head, the right side film cloth is separated from the left continuous mother body. Since there is no clamping positioning mechanism and closed-loop tension control system, the film cloth is prone to tension fluctuation during unwinding and film coating. This uncontrolled tension will cause the film cloth to stretch, which will further cause wrinkles or tearing defects.

[0007] 3. Insufficient automation in the transferring link

[0008] The existing technology generally lacks an automatic transferring module after cutting, relies on manual operation, and has a long transfer time and low efficiency. Manual operation can increase the pollution rate of the film cloth and the wrinkle defect rate.

[0009] 4. Storage defects after transferring

[0010] The storage mechanism of the film cloth is mostly a fixed structure with a fixed volume and low space utilization, resulting in high storage costs. The storage mechanism is mostly designed in an open manner, which exposes the film cloth to the air, has poor dustproof performance, and is prone to oxidation and dust pollution. The sorting adaptability of the storage mechanism is poor, and it cannot meet the multi-station sorting and storage demand. SUMMARY

[0064] As shown in Figure 9 , the folding telescopic guide rail group 603 is divided into two groups, each group is composed of multiple layers of sliding rails that can slide left and right, and the four folding telescopic guide rail groups 603 are four layers of sliding rails, three layers of sliding rails, two layers of sliding rails and one layer of sliding rails from top to bottom, so that the four folding telescopic guide rail groups 603 can support the four film cloth loading boxes 605 to be opened in stages from top to bottom.

[0065] As shown in Figure 4 , Figures 7-8 and Figures 10-11 , the lower left corner of the fixed base frame 601 is intermittently pressed and locked with the positioning plate 303, and the left wall of the five film cloth loading boxes 605 is on the same vertical line with the sliding path of the cutting laser 504, so that after the five cutting lasers 504 synchronously cut the film cloth, the block film cloth vertically falls into the film cloth loading box 605.

[0066] In use, the film cloth sub-packaging transfer trolley 6 is conveyed into the installation frame 302 in an extended open state, the transmission wheel 602 rotates to assist the movement of the film cloth sub-packaging transfer trolley 6, and the film cloth sub-packaging transfer trolley 6 moves from right to left between the installation frames 302 until it abuts against the positioning plate 303. When the five film cloth loading boxes 605 are opened, they correspond to the cutting paths of the five cutting lasers 504 respectively, and the five cutting lasers 504 cut the film cloth synchronously. After cutting, the block-shaped film cloth falls vertically into the film cloth loading box 605. In this way, the block-shaped film cloth after cutting is automatically stored in stages, reducing manual intervention and avoiding pollution, wrinkles and breakage of the film cloth caused by manual contact. The above cutting action is repeated to fill the five film cloth loading boxes 605 with film cloth. Then, the transmission wheel 602 is started to drive the film cloth sub-packaging transfer trolley 6 to exit the installation frame 302, which has high automation, short time consumption and high efficiency. When storing or transporting the film cloth, the folding drive connecting rod 608 is rotated counterclockwise along the support 607. The limiting shaft 610 slides in the limiting groove 609. With the rotation of the folding drive connecting rod 608, the multiple layers of the folding telescopic guide rail group 603 are synchronously slid leftward to contract, so that the folding drive connecting rod 608 is parallel to the vertical surface of the fixed base frame 601. Then, the five film cloth loading boxes 605 are vertically stacked in a column. In this way, when storing or transporting the film cloth, the volume of the film cloth sub-packaging transfer trolley 6 is compressed, the space utilization is improved, and the storage cost is reduced. The film cloth loading boxes 605 are sealed after folding, which improves the dustproof and anti-oxidation performance. When subsequent film cloth needs to be sorted and processed, the folding can be opened to meet the demand of multi-station sorting, which has strong sorting adaptability.
