Braid feeding device for surface mount system and using method of braid feeding device for surface mount system

Abstract

The invention discloses a braid feeding device for a surface mount system. A base, a mechanical arm, slide rail bases, first slide bases, connection plates and a transmission box are included; the mechanical arm is installed on the top of the base, and an installing plate is horizontally installed at one end of the mechanical arm; the top side of the installing plate is provided with an installing groove; and a plurality of hollow pipes are installed in the installing groove, and suction cups are installed at the bottom ends of the hollow pipes. According to the braid feeding device for the surface mount system, the hollow pipes are installed in the installing groove through fastening nuts and limiting bottom plates, the hollow pipes and the suction cups are installed according to the number of patches specifically needed on a PCB bonding pad, the needed patches are taken for use at a time, and the work efficiency of the surface mount system is greatly improved; patch braids are compressed through pressing wheels at the bottom of an installing base, and it is guaranteed when the patches are taken for use, the braids are tightly attached to the base; and a servo motor on a fixed arm is used for driving a rotating arm to rotate and adjust an angle and a tensioning wheel is driven to rotate as a whole, so that it is guaranteed that the patch braids are in a tightened state, and the braids can be flat easily during conveying.

Description

technical field [0001] The invention relates to the field of placement devices, in particular to a braiding feeding device for a placement machine and a method for using the same. Background technique [0002] The placement machine is also called "mounting machine" and "surface mount system". In the production line, it is configured after the dispensing machine or screen printing machine, and the surface mount components are accurately placed on the PCB by moving the placement head. A device on the pad, which is divided into manual and fully automatic, and the tape feeding device is a device in the placement machine that removes the patch from the tape and places it on the PCB pad. [0003] When the braid feeding device of the existing placement machine is conveying the braid, the braid is prone to folding and unevenness during the conveying process. Perform precise positioning, and when removing the patch on the braid, the braid will loosen with the patch, and the braid fe...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of braid feeding device and using method thereof for placement machine, in order to overcome the braid feeding device of above-mentioned existing placement machine when conveying braid, braid is in conveying process Folding and unevenness are easy to occur, and the braid is loose during conveying, which makes it difficult to accurately position the patch on the braid, and when the patch on the braid is removed, the braid will be along with the patch If it is loose, it is necessary to shut down and adjust the braid feeding device and braid before continuing to use it; when the patch is taken by the robotic arm, it cannot be taken at one time according to the specific number of patches required on the PCB pad, and repeated operations are required.
