Today's electronic products are becoming increasingly sophisticated and intelligent. You should know that more sophisticated electronic products often require higher manufacturing processes. Imagine: taking and installing a large number of precision, small, and fragile components in a complex internal structure and limited space, while also considering product yield and production line utilization rate. This is undoubtedly a great challenge for electronic product assembly equipment.
In the field of electronic product assembly, efficient and precise control of vertical Z-axis motion is the key factor affecting product yield. To improve the efficiency of Z-axis movement, the assembly equipment must solve multiple problems such as force control, force sensing, position feedback, direct drive mechanism, and lightweight size, and shorten the production cycle time as much as possible in order to overcome the pain points of process yield. Like the toe technique of a dancer, it is not only a technique but also an art.
Delta LPL Micro Linear Motor Module is designed for Z-axis!
In order to meet the high precision process requirements, Delta LPL micro linear motor module innovation has been launched. This is a linear motion module that integrates a linear motor, optical ruler, force sensor, small rotary servo motor, encoder, slide rail, and frame.
Extremely lightweight, light and agile
Delta LPL is exquisitely designed and highly integrated. The thinnest model is only 12mm wide, with a minimum linear and rotational width of 13mm; And the linear motor directly converts electrical energy into linear motion, which reduces mechanical wear and energy loss compared to the traditional "servo motor+ball screw" two in one design. The no-load acceleration exceeds 6g, improving the overall efficiency of the system.
Precise control of subtle power
The precision of force control is highly required during Z-axis motion. Excessive or insufficient force can lead to component damage or poor assembly.
Delta LPL adopts high-precision force sensors and advanced control algorithms to achieve subtle force control (within a minimum of 0.1N and a repeatability of ± 0.5%), ensuring that the force of each operation step is within a safe range.
High precision positioning and timely feedback
The Delta LPL has a built-in linear optical ruler with a resolution of 0.5um and a rotary encoder with a resolution of 20 bits, which can achieve precise feedback on the Z-axis motion position, ensuring that the components can be accurately placed in the predetermined position;
By improving the rigidity and stability of the mechanical structure, the positioning accuracy can also be further enhanced.
Gentle protection to reduce losses
Delta LPL has a soft landing function, which smoothly and smoothly completes the picking, placing, and installation of fine components, achieving process efficiency, yield, and power optimization while reducing equipment losses.
Ballet dancers control the power output of their footsteps during jumping, spinning, and other movements to ensure the stability and accuracy of their movements. The control of foot strength not only affects the smoothness and beauty of dance, but also directly relates to the rhythm and expressiveness of dance.
Delta LPL has made breakthroughs and innovations in Z-axis motion, and has successfully introduced application scenarios such as pick and place labeling, 3C assembly, high-density surface mount, AOI detection, etc., contributing to the automation capacity upgrade of enterprises in precision electronic assembly and semiconductor industry.
