There are many types of fully automatic board splitting machines, among which there are many kinds of board splitting machines with unlimited length. The board splitting machine with unlimited length refers to the extension of a worktable (different platform lengths can be customized according to the length of PCB panels to be processed) on the original worktable of the board splitting machine, which is convenient for placing the circuit boards to be processed and the circuit boards with long strips to be processed. Therefore, the lengthening dividing machine has better advantages for processing ultra long light strip board, aluminum substrate, glass fiber circuit board, etc.
The following will introduce two models of the lengthening divider:
Multi knife walking plate splitting machine, which is transformed from one group of circular knives to three groups of circular knives, can better ensure the cutting quality of PCB panels, with less cutting stress, less deformation and more wear-resistant blades.
1. The lamp strip dividing machine adopts a unique cutting method. The circuit board cutting is completed by six blades. The upper and lower blades form a group to form a cutting unit, which are groups a, B, C and C respectively. The whole cutting process is divided into three stages. Group a blades first cut the circuit board by 40%, then blade B rolls it through the groove cut by blade a again, and then completes 40% of the cutting amount. Finally, group C blades cut the last 20% and polish it. Due to the small cutting amount each time, the stress generated in the cutting process is reduced by more than 80% compared with the traditional one-time cutting method, The edge of the divided circuit board is flat and smooth, and the board surface is very flat without twisting and warping. It is the only machine on the market that can ensure that the aluminum substrate will not deform after cutting;
2. Due to multiple cutting, the cutting process is very stable, which greatly improves the positioning ability of the V-CUT slot. Even for the circuit board with very shallow V-CUT slot, the V-CUT slot will not jump out of the guide knife, so as to avoid adverse effects;
3. Due to the small cutting force of the blade and the use of high-speed steel materials imported from Japan, the durability of the blade is greatly improved, and the service life of the blade can reach more than one year when dividing the aluminum substrate;
4. All cutting blades of the light strip dividing machine are calibrated with an exciting dual frequency laser interferometer to ensure that the rear knife can accurately continue cutting in the groove cut by the front knife. The tool tip runout shall not be greater than 0.02mm. Ensure perfect cutting quality.
The worktable of aluminum substrate dividing machine can be extended as needed
1. The cutter type LED dividing machine adopts electric hybrid design and double straight knife cutting, which is especially suitable for cutting precision SMD thin plate and aluminum circuit board;
2. Guillotine cutting is applicable to PCB of various thickness, and the cutting stroke is less than 2mm, without potential safety hazards;
3. The internal stress generated during plate cutting can be reduced below 600 to avoid tin cracking and damage to precision parts;
4. The cutter type LED dividing machine can cut the edge of V-groove and parts with a width as low as 0.3mm and a height of 60mm.
