Mount flexibility, also referred to as a mount elastic flexibility.
People on Mount flexible have been able to familiar with the SMT industry, but what is the mount flexibility? What is the standard of flexible placement machine? Placement accuracy, Mount speed and placement capability can be quantified into specific data, mount flexible able to quantify it?
Obviously, flexibility, accuracy and speed, can not be accurately quantified. Flexible advanced and innovative features, it's just a concept, dynamic, relative to the device characteristics described.
Starting from the actual production requirements, the mount flexibility should include the following aspects.
(1) able to adapt to different PCBA products
This is a flexible the basic requirements of the machine. Refers to "adapt" to the a placement machine models on the face of a variety of products, rather than the traditional high-speed multifunction machine combination.
Different PCBA products may be of different types, the Daxiao different thicknesses, different materials, different surface coating of the PCB, thus Mounter PCB conveyor, clamping, support and basis of the ability to identify requirements vary, and may chip mode, the detection methods and have different requirements for placement force. Flexible placement machine should be able to adapt to these different variables of the PCB, without requiring the user to transform models.
Different PCBA products contain different components. The number and proportion of the chip components, the fine chip components (0201 and 01005) of the species, and the size of the IC package, type and pitch of the profiled element types, sizes and surface properties are of the mounter Post installed capacity to the different requirements. Flexible placement machine should be able to adapt to these changes in different components, without the need for user to transform models or additional investment.
(2) to be able to balance between accuracy and speed
This one is also a flexible basic requirements of the machine. Usually in the placement machine characteristics, flexibility and speed, flexibility and accuracy, and speed and precision are mutual constraints contradiction exists. Mount Flexible often sacrificing speed, to improve the accuracy can not but the rate of loss, and enhance the flexibility and improve the accuracy nor is fine. However, the modern assembly technology is to challenge these contradictions, requires flexible process to reconcile the accuracy and speed, so the three go hand in hand, to achieve dynamic balance to achieve the best fit.
The good news is that modern science and technology innovation, with the development of the equipment manufacturing technology, the above contradictions are solved step by step, to a certain extent have been flexible placement machine can achieve high precision and high speed.
(3) rapid production conversion
The flexible basic purpose is to achieve small batch production of high-efficiency multi-species, and therefore relatively high conversion and set the fastest production time. Mainly parts can be quickly replaced by flexible configuration system and state-of-the-art in the open, the high efficiency of the offline programming Mounter software system to achieve rapid conversion. Mounter new theoretical conversion time has been shortened to 30 ~ 1 5 min, of course theoretical placement speed, these equipment suppliers are given the data comparison and reference role.
(4) capable of upgrading
This one is also improved machine flexible requirements. Placement equipment as production investment, expect to achieve maximum efficiency is an inevitable requirement, but the ever-changing in the market today, requires investment companies to be able to accurately estimate future product direction and types, obviously not every business has the ability. Thus requiring the placement machine to be able to have the flexibility in the following case.
Large changes in the scale of production (usually to expand production capacity) be able to adapt to the new requirements by adding modules or replacement parts ways rather than re-purchase of equipment. For example, the simplest configuration for 6 stickers titles gantry placement machine, the placement rate of 30 000 cph can add modules to to 5 000 cph increase gradually expand production.
· By adding modules or replacement parts in large changes in the product range to meet the requirements of the new product placement. For example, a new placement machine can mount IC package 30 mm × 30 mm, 50mm × 50 mm Mount range can be extended to configure special placement head.
· Upgrading of placement machine and equipment manufacturing new technology can be implemented with little cost.
