Abstract

The invention provides a placement device comprising a servo motor, a placement main shaft, a placement sucker and a sensing device. The servo motor is connected with the placement main shaft and is used for driving the placement main shaft to rotate; the placement main shaft is connected with the placement sucker and is used for driving the placement sucker to rotate; the placement sucker is used for sucking an electronic element for placement; and the sensing device is connected with the servo motor and is used for sensing a rotating angle of the placement main shaft and generating a sensing signal when the placement main shaft rotates to a preset angle so that the servo motor drives the placement main shaft to stop rotating according to the sensing signal. The placement device has lower cost, reasonable structure, good exchangeability, and the placement precision and the efficiency satisfy the production requirements. The invention also provides a method for placing electronic elements by utilizing the placement device.

Description

technical field [0001] The invention relates to the technical field of electronic component placement, in particular to an electronic component placement device and a placement method. Background technique [0002] Printed circuit boards and integrated circuit chips are widely used spare parts in electronic consumer products. On printed circuit boards and integrated circuit chips, electronic components such as resistors, capacitors, and inductance components need to be mounted and welded. Surface Mount Technology (SMT) has been widely used in the assembly of electronic components and printed circuit boards due to its high reliability and ease of automation. See Stretchable Electronic Systems, IEEE Electronics Packaging Technology Conference, 6-8 Dec. 2006 Page(s): 271-276. However, it is necessary to rely on high-precision and high-efficiency placement machines to mount and solder electronic components with smaller and smaller sizes and various shapes and specifications on ...
