Description

Auxiliary fixing jig of PCB (printed circuit board) chip mounter

[ technical field ] A method for producing a semiconductor device

The utility model relates to a circuit board technical field especially relates to a supplementary fixed tool of PCB board chip mounter.

[ background of the invention ]

The PCB is also called a printed circuit board, and is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. It is called a "printed" circuit board because it is made using electronic printing. PCB boards have evolved from single-layer to double-sided, multi-layer, and flexible, and still maintain their respective trends. A PCB (printed Circuit Board) chip mounter is equipment which conveys a PCB to a designated position and then accurately places surface-mounted components on the PCB through a movable mounting head, wherein the mounting positions of the components are important factors influencing the quality of the PCB. But the thickness of the fixed PCB plate jig of the chip mounter that is used at present is fixed, and the fixed jig of PCB plate can't be general, when leading to the fixed jig paster of thickness difference, need change fixed jig, consume the manpower to the jig cost is higher, very big occupation fund.

The utility model discloses it is not enough to solve prior art and research and propose.

The utility model discloses can realize through following technical scheme:

the utility model discloses a supplementary fixed tool of PCB board chip mounter, which comprises a bracket, the support contains upper fixed plate and bottom plate, upper fixed plate has constituted the fixed interval of PCB board with the bottom plate, be fixed with a plurality of supporting mechanism on the fixed interval, supporting mechanism contains the fixed block, be fixed with the guide pulley with fixed block roll connection in the middle of the fixed block, the fixed block top is fixed with the pillar, the pillar upper end pass aforementioned upper fixed plate and with upper fixed plate swing joint, the spring has been placed between fixed block and the aforementioned upper fixed plate, the pillar all passes the spring that corresponds, the support both sides all are fixed with the motor, the motor all is connected with the transfer roller. The PCB board passes through the motor and drives the transfer roller and rotate and move the PCB board along the inside removal of supporting mechanism below to the tool, after the PCB board moved the assigned position, the motor stopped, the chip mounter of tool top fixes electronic component on the PCB board, after the paster was accomplished, the transfer roller antiport, shift out the PCB board in the fixed tool, because the supporting mechanism passes through the distance between spring regulation guide pulley and the lower fixed plate, when getting into fixed tool to the PCB board of different thickness, extrude the fixed block through the spring, the homoenergetic fixes the PCB board.

Preferably, the vertical highest position of the conveying roller is flush with the upper end face of the lower fixing plate. When the conveying roller sends the PCB into the fixed jig, the PCB can be conveyed to the upper end face of the lower fixed plate.

Preferably, still be fixed with a plurality of fixed columns on the up-per fixation board lower extreme face, the fixed column is the tourus, and corresponding fixed column is all passed to aforementioned pillar.

Preferably, the transfer roller is made of an elastic material.

Preferably, the conveying rollers are all arranged right below the guide wheel.

Compared with the prior art, the utility model has the advantages that:

the PCB board is along in the bottom plate up end gets into fixed tool, PCB board extrusion guide pulley, and the spring shortens, and fixed tool can fix the PCB board of different thickness.

2. Drive the transfer roller through the motor and rotate, in advancing fixed tool with the conveying of PCB board, reach and transport out the PCB board from fixed tool through the transfer roller after the paster is accomplished, avoided artifical fixed and take off the PCB board, practice thrift the human cost.
