Types and maintenance of PCB splitter

PCB splitter, also known as circuit board splitter, is widely used in electronic product manufacturing. The early plate splitting machines used manual plate splitting, with low efficiency and great damage to the substrate. Some plates even had inserted components, so this processing method was eliminated after the development of mechanization. Now let's introduce the types and maintenance of PCB splitter. Welcome to read!

Types of PCB splitter:

Common PCB splitting machines mainly include laser splitting machine, curve splitting machine, knife walking splitting machine, guillotine splitting machine, stamping splitting machine, hand pushing splitting machine and milling cutter splitting machine.

Laser splitting machine is a new technology. With the development of laser technology, laser technology is applied more and more in the field of electronic manufacturing. The application in PCB splitting is one of them. Different lasers are used according to the demand. At present, UV laser, CO2 laser, green laser and picosecond laser can be selected, and the natural price is also very different. In terms of comprehensive cost performance, UV laser and green laser are the mainstream at present.

The advantages of laser plate splitting machine are cutting efficiency and cutting effect. The cutting edge is free of carbonization and burr. And it has adsorption function, which makes it dust-free and smokeless. The laser adopts a non-contact processing method, with small thermal impact, no damage to the substrate or the substrate of active devices, and no stress. CCD positioning and computer-controlled automatic cutting can also realize the function of automatic loading and unloading. Greatly improve the production efficiency of the equipment and save labor costs.

The defect of several PCB splitting equipment, such as curve splitting machine, knife walking splitting machine, guillotine splitting machine, stamping splitting machine, hand pushing splitting machine and milling cutter splitting machine, is that they all have contact processing methods, which will produce stress and hurt the substrate. There are burrs on the cutting edge and a large amount of dust will be generated, which is not conducive to the development needs of sustainability and environmental protection.

Maintenance of PCB splitter:

1. Common reasons why PCB splitter cannot run or cannot run: lack of battery charging; The connecting line between the battery and the starting motor is disconnected, and the knife type dividing machine. Loose wiring clip or serious oxidation of battery pole; The electromagnetic switch deflector is severely ablated or has poor contact with the two terminals; The brush is excessively worn, the spring is broken, or the brush is stuck in the brush holder; There is oil stain between the brush and the rectifier or the rectifier is severely ablated;

2. Partial short circuit or open circuit of winding; The armature winding and commutator piece have desoldering points; The bearing or copper sleeve is worn, causing the rotor to sweep the bore; When installing the device, the four brushes are installed incorrectly or the clearance of the newly replaced shaft sleeve is too large. When starting the PCB splitter, the shift fork device is incorrect, and the shift fork sliding column device is in the moving bushing, so that the motor gear can not rotate with the shift fork. Contact of electromagnetic switch is too early, engagement gear is not engaged

3. The starting motor of PCB splitter has turned. The gap between the iron core of the electromagnetic switch and the push rod of the connecting plate is too large. The one-way clutch slips and cannot drive the flywheel ring gear to rotate. The gear of the starting motor is severely worn and cannot mesh with the flywheel ring gear. The so-called electromagnetic switch is always on and always on. The so-called electromagnetic switch is always on and always on. It means that after pressing the start switch, the iron core of the electromagnetic switch will be taken off as soon as it is sucked up. After taking off, it will be sucked up immediately and then taken off immediately, which can not achieve the purpose of starting the initiator. The common reason for this problem is to insist on the open circuit of the coil.
