PCBA Tech - Increase the production and sales rate of SMT placement machines?

The placement machine is suitable for PCB circuit assembly in the field of industrial electronic equipment and military electronic equipment. Let me share with you how to increase the production and sales rate of the placement machine production line?

One, placement program processing

The production line consists of multiple equipment, including solder paste printers, placement machines, reflow soldering, etc., but in practice the speed of the production line is determined by the SMT placement machine. A production line of placement machines usually includes a high-speed machine and a high-precision placement machine. The former mainly mounts chip components, while the latter mainly mounts IC and special-shaped components. When the two placement machines complete a placement process (hereinafter referred to as placement time) at the same time and the smallest, the entire SMT production line has exerted its maximum production capacity. In order to achieve this goal, we can process the placement process as follows.

1. Load distribution balance. Reasonably allocate the number of placement components for each device, and try to make the placement of each device even at all times. When we first allocate the number of components to be placed on each device, it often appears that the distance between the placement time is relatively large. This requires that the production load of all equipment on the production line be adjusted according to the placement time of each device. Part of the components on the equipment with a long installation time is moved to another equipment to complete the load distribution balance.

2. Equipment optimization. Each placement machine has a maximum placement speed value. The placement machine speed claimed by many placement machine manufacturers is often not achieved in practice, but in practice this speed value must be completed under certain conditions . Optimizing the numerical control program of each device is to make the placement machine meet these conditions as much as possible in the production process, and then complete the highest speed placement and reduce the placement time of the equipment. The optimization criterion depends on the structure of the device.

2. Eliminate bottlenecks

The SMT production line is composed of multiple automation equipment. When the speed of one equipment is slower than other equipment, then this equipment will become a bottleneck that limits the speed improvement of the entire SMT production line. Generally, the bottleneck is often present on the placement machine. To eliminate the bottleneck phenomenon, it can only be completed by adding a placement machine. Of course, this requires a large capital investment, but this can make full use of the excess production capacity of other equipment, which is far more cost-effective than investing in another SMT production line. Which type of placement machine to add depends on the bottleneck of the production line. Under normal circumstances, it is best to purchase a high-speed, multi-functional placement machine, because it has the characteristics of both high-speed and high-precision machines. The scale of the device covers both high-precision machines and high-speed machines, and it can handle bottlenecks caused by high-speed machines or high-precision machines. And now the development trend of placement machines is also developing in this direction to meet the needs of shopping malls.

Adding a placement machine to the production line can handle bottlenecks and speed up the rhythm. This method provides more production capacity and more feeder positions to better balance the production line without significantly Adding production line management complexity is far greater than the improved production capacity of adding a placement machine alone.

3. Implement strict and useful handling methods

SMT equipment is a mechatronics fine equipment. Implementing strict and useful handling methods in operation is an important way to improve the power of SMT production lines. For example, the components to be compensated in advance are installed on the spare feeder; the production line installs the last few pieces of the previous batch number together, and prepares for the next batch of products on the production line, and so on.

The SMT production line is a large production line, and the output is calculated in seconds. In addition to equipment and environmental factors, the fluency of production and the quality of products, the human factor occupies an extremely important component, which improves the production power. Special attention should be paid to the training of employees. In addition to regular professional skills training, professional SMT books and periodicals organize employees' learning for teaching materials, cultivate a love for SMT, and improve everyone's general professional level.

Regular inspection and maintenance of SMT equipment is also one of the powerful guarantees to ensure its full effectiveness. Many companies tend to ignore this point in the production process because of the heavy production tasks. Once the equipment cannot be produced normally due to a fault, the loss caused by the strike is far greater than the cost of regular shutdown inspection and maintenance of the equipment. Therefore, we must focus on scientific inspection and maintenance of the equipment regularly to keep the equipment in an outstanding condition.
