As we all know, for SMT patch manufacturers, it is very necessary to increase the placement speed of the placement machine, because the placement speed represents the productivity. The speed of the SMT placement machine is generally divided into theoretical speed and actual speed: The theoretical speed refers to the placement speed of the placement machine in the optimal state, including the optimum of the feeder installation sequence, placement sequence, and placement head selection. The speed under the arrangement; the actual speed is in the actual production situation, and various conditions are not optimal due to the specific conditions, so the actual speed is generally lower than the theoretical speed. However, if you want to improve the placement speed of the placement machine, you need to consider from many aspects. The following Sanjing will introduce you:

(1) Improve the structure of the SMT placement machine: ① Use dual-track instead of one track for PCB placement, and the other track to send the board, reducing PCB delivery time and placement time; ②Multiple placement head combination; ③Arch frame structure Both ends are driven together to avoid the cantilever effect and reduce the mechanical stability time; ④The combined multi-unit structure focuses on the unit area mounting speed.

(2) Improve the placement head and nozzle of the SMT placement machine: ① Change to the lightning placement head and multi-nozzle knot structure; ② Use the high-reliability and high-adaptability nozzle.

(3) Motion drive and linear motor skills for SMT placement machines: ①The X-axis operation uses a dual-motor drive system with a fully synchronized control loop to speed up the running speed; ②Selects high positioning and high repeat accuracy, high speed and high acceleration, and work Patented linear motor with low current and high precision control.

(4) The placement machine must have a fast detection function: use advanced image processing and arithmetic software, separate detection of one-piece components and large-size ICs, and fast image acquisition and conversion circuits.

(5) Improve the feeder skills of the SMT placement machine: ①The feeding method of the intelligent feeder can shorten the replacement time of components and reduce the manual error; ②Recharging without stopping the machine; ③Using a large-capacity feeder, using more materials Try to use tape packaging for the devices.

(6) Optimize the placement program of the SMT placement machine: reduce the number of nozzle changes and the time for placement and picking.

(7) Improve SMT placement machine software technology: ①Intelligent operating system, various forms of PCB files, directly optimize the generation of placement program files, reducing manual programming time; ②Offline programming is selected for multiple varieties and small batches.

(8) Operate the machine in accordance with the safety operation guidelines, and regularly maintain the SMT placement machine.

The above is about how to improve the placement speed of SMT placement machine, I hope it can be helpful to everyone!
