How to improve smt production line capacity
The SMT production line consists of multiple equipment, including solder paste printers, SMT placement machines, reflow soldering, etc., but in fact the speed of the production line is determined by the SMT placement machine. An SMT placement machine production line usually includes a high-speed machine and a high-precision placement machine. The former mainly mounts chip components, while the latter mainly mounts ICs and special-shaped components. When the time for the two placement machines to complete a placement process (hereinafter referred to as the placement time) is equal and the smallest, the entire SMT production line has exerted its maximum production capacity. In order to achieve this goal, we can deal with the placement process as follows.
1. Load distribution is balanced. Reasonably allocate the number of placement components for each SMT placement machine, and try to make the placement time of each device equal. When we allocate the number of placement components for each SMT placement machine for the first time, there will often be a large gap in placement time. This requires adjustments to the production load of all equipment on the production line according to the placement time of each device. Move part of the components on the SMT placement machine with a long placement time to another placement machine to achieve a balanced load distribution.
2. Equipment optimization. Each SMT placement machine has a maximum placement speed value. The placement machine speed claimed by many SMT placement machine manufacturers is often not reached in actual production, but in fact, this speed value must be under certain conditions Achieved. Optimizing the numerical control program of each device is to make the SMT placement machine meet these conditions as much as possible in the production process, so as to achieve the highest speed placement and reduce the placement time of the equipment. The principle of optimization depends on the structure of the device.
3. Improve the efficiency of the production line by eliminating the bottleneck of the SMT production line
Adding an SMT placement machine to the production line can solve the bottleneck problem and speed up the rhythm rate. This method provides more production capacity and more feeder positions to better balance the production line without significantly increasing The complexity of production line management is far greater than the increased production capacity of a single placement machine. In this regard, ETON’s high-precision, high-speed and multi-function placement machine can meet this demand.
4. Improve the efficiency of the production line by implementing strict and effective management measures on the SMT production line
In short, the method to improve the efficiency of the SMT placement machine production line is generally the same as the quality management method, considering people, machines, materials, methods, and circles. However, improving the efficiency of the SMT placement machine production line focuses on starting from the machine and human factors.
