Description

SMT yin-yang furnace carrier

Technical Field

The utility model relates to the technical field of computer accessory production, in particular to an SMT yin-yang furnace carrier.

Background

SMT is an abbreviation of surface mount technology, which is an electronic mounting technology for directly attaching and welding surface assembly components (including resistors, capacitors, inductors, etc.) to the surface of a circuit board by using special automatic assembly equipment such as a solder paste printer, a chip mounter, reflow soldering, etc., and is one of the common technologies in computer accessory production.

When SMT paster passes the stove, current stove carrier inconvenient place the location to the circuit board, the circuit board easily takes place to rock in the carrier, leads to SMT quality unstable.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model aims to provide an SMT yin-yang furnace carrier,

in order to achieve the above purpose, the utility model adopts the following technical scheme:

an SMT yin-yang furnace carrier, which is characterized in that: including carrier base and carrier body be fixed with a plurality of locating pieces on the carrier base, a plurality of locating pieces enclose with the placing area of carrier body looks adaptation be provided with a plurality of reference columns in the placing area, the carrier body sinks to be formed with first standing groove and second standing groove, and first standing groove and second standing groove symmetry set up four apex angles of first standing groove and second standing groove all seted up with reference column matched with locating hole, just the upper end of reference column can stretch into in first standing groove and the second standing groove a plurality of through-holes of dodging have been seted up at the center of first standing groove and second standing groove.

Further, the carrier base comprises a bottom plate and a top plate connected above the bottom plate through a supporting plate, and the positioning blocks and the positioning columns are fixed on the top plate.

Furthermore, the periphery of the top plate is provided with a taking notch.

Furthermore, the positioning blocks are L-shaped, and the four positioning blocks are respectively arranged at the four top angles of the top plate.

Further, the left side and the right side of the first placing groove and the second placing groove are respectively provided with a plate taking groove.

The utility model has the remarkable effects that:

1. the two sides of the PCB are respectively supported by the first placing groove and the second placing groove which are symmetrically arranged, so that one carrier can finish the furnace passing processing of the PCB on the male and female sides, the processing time is saved, the processing efficiency is improved, and the reject ratio of Pin contact of the PCB during processing is reduced;

2. the positioning column on the carrier base is used for positioning the carrier body and the PCB together, so that the skill is high, the setting of the positioning structure is reduced, the structure of the carrier can be simplified, the positioning consistency of the carrier and the carrier can be ensured, the tolerance of the PCB and the carrier during solder paste brushing is avoided, and the accuracy of the splicing is improved.

Detailed Description

The following describes the embodiments and working principles of the present utility model in further detail with reference to the drawings.

As shown in fig. 1-4, an SMT yin-yang furnace carrier comprises a carrier base 1 and a carrier body 2, wherein a plurality of positioning blocks 3 are fixed on the carrier base 1, a placement area matched with the carrier body 2 is surrounded by the plurality of positioning blocks 3, a plurality of positioning columns 4 are arranged in the placement area, the carrier body 2 is sunk to form a first placement groove 5 and a second placement groove 6, the first placement groove 5 and the second placement groove 6 are symmetrically arranged, positioning holes 7 matched with the positioning columns 4 are formed in four top angles of the first placement groove 5 and the second placement groove 6, the upper ends of the positioning columns 4 can extend into the first placement groove 5 and the second placement groove 6, and a plurality of avoidance through holes 8 are formed in the centers of the first placement groove 5 and the second placement groove 6 to give way to electronic components on a circuit board.

As can also be seen from fig. 1, the carrier base 1 comprises a base plate 11 and a top plate 13 connected above the base plate 11 by a support plate 12, wherein the positioning blocks 3 and the positioning columns 4 are fixed on the top plate 13.

Further, in order to facilitate placing and taking the carrier body 2, the production efficiency is accelerated, and the peripheral side of the top plate 13 is provided with a taking notch 14.

In this example, the positioning blocks 3 are L-shaped, and the four positioning blocks 3 are respectively arranged at four top corners of the top plate, so that rectangular placement areas consistent with the shape of the carrier body 2 are formed by the four positioning blocks 3, and positioning of two sides of the carrier body 2 can be realized by one positioning block 3.

Further, for the convenience put, get the circuit board for production efficiency first standing groove 5 and the left and right sides of second standing groove 6 have all seted up and have got board groove 9.
