Description

General carrier suitable for subsides of multiple dysmorphism PCB subsides

Technical Field

The utility model belongs to the technical field of the PCB pastes dress instrument and specifically relates to a general carrier suitable for subsides of multiple dysmorphism PCB dress.

Background

With the development of science and technology, electronic products are developed towards the trend of high density, multiple functions and miniaturization, and the design space of the PCB and the irregular appearance of the PCB are limited, so that a 5mm clamping edge of automatic equipment cannot be reserved during the design of the PCB; due to the limitation of the external dimension precision and the appearance of the PCB, the PCB cannot increase the process margin. Therefore, when the PCB is to be mounted by adopting the automatic equipment, a special mounting carrier needs to be manufactured according to the shape and the size of the PCB and the supportable position on the PCB, and due to the tolerance of the processing precision of the carrier and the supplied materials of the PCB, the PCB is shaken after being placed into the special carrier, so that the mounting precision is poor and the consistency is poor. Moreover, a special patch carrier can only be suitable for one product, and for the practical situation of small batch and multiple varieties, the cost for manufacturing and managing the special patch carrier is not small.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a following technical scheme realizes: the utility model provides a general carrier suitable for subsides of multiple dysmorphism PCB dress, includes magnetic carrier dish and magnetism movable block, the inside chamber that holds that is equipped with of magnetic carrier dish, the bottom of magnetism movable block adsorb in hold the bottom surface in chamber and can follow the bottom surface that holds the chamber removes.

Further, the magnetism movable block includes the magnetism base, the magnetism base upwards extends and extends the post, be equipped with the thimble directly over extending the post, the magnetism base adsorb in hold the bottom surface in chamber.

Further, the magnetic base and the thimble are both cylindrical.

Further, the inside that holds the chamber still is equipped with magnetism activity strip, the bottom of magnetism activity strip adsorb in hold the bottom surface of chamber, the lateral part butt of magnetism activity strip in hold the lateral wall of chamber and can follow the lateral wall that holds the chamber removes.

Further, the magnetism activity strip still is equipped with first mounting groove, magnetism carrier dish still is equipped with the second mounting groove, first mounting groove with the second mounting groove is located the coplanar.

The utility model has the advantages that: through will adsorbing the magnetism movable block in the bottom surface that holds the chamber to can adjust the position along the bottom surface that holds the chamber at will, nimble provide some support to PCB. The magnetic carrier disc and the magnetic movable block are flexibly configured, and the mounting requirements of PCBs with different sizes and different appearances can be met through the support provided by the magnetic carrier disc and the magnetic movable block. Because the magnetic movable block is movably adjustable, the situation that the PCB shakes due to tolerance of the special carrier does not exist. The carrier overall dimension is fixed, has avoided adjusting equipment guide rail width when trading the line, has improved trade line efficiency, and the dress that is applicable to many varieties small batch PCB is pasted in the preparation demand.

Detailed Description

For a more clear and complete description of the technical solution of the present invention, the following description is made with reference to the accompanying drawings.

Referring to fig. 1-2, the utility model discloses a general carrier suitable for subsides of multiple dysmorphism PCB subsides, including magnetic carrier dish 1 and magnetic movable block 2, magnetic carrier dish 1 is inside to be equipped with and to hold chamber 11, the bottom of magnetic movable block 2 adsorb in hold the bottom surface of chamber 11 and can along the bottom surface that holds chamber 11 removes.

In this embodiment, it is preferable that the magnetic carrier plate 1 is made of iron, the number of the magnetic movable blocks 2 can be set according to the PCB to be clamped, the magnetic movable blocks 2 are attracted to the bottom surface of the accommodating cavity 11, and the position of the magnetic movable blocks can be adjusted at will along the bottom surface of the accommodating cavity 11, so as to flexibly provide point support for the PCB. The magnetic carrier disc 1 and the magnetic movable block 2 are flexibly configured, and the mounting requirements of PCBs with different sizes and different appearances can be met through the support provided by the magnetic carrier disc 1 and the magnetic movable block. Because the magnetic movable block 2 is movably adjustable, the situation that the PCB shakes due to tolerance of the special carrier does not exist. The carrier overall dimension is fixed, has avoided adjusting equipment guide rail width when trading the line, has improved trade line efficiency, and the dress that is applicable to many varieties small batch PCB is pasted in the preparation demand.

Further, the magnetic movable block 2 includes a magnetic base 21, the magnetic base 21 extends upwards to form an extension column 22, a thimble 23 is disposed right above the extension column 22, and the magnetic base 21 is adsorbed on the bottom surface of the accommodating cavity 11.

In this embodiment, the thimble 23 can correspond to a hole preset on the PCB for mounting, so that the PCB is more tightly fixed.

Further, the magnetic base 21 and the thimble 23 are both cylindrical.

In this embodiment, since the holes for mounting preset on the PCB are substantially circular, the circular thimble 23 can be more smoothly matched with the holes during mounting.

Further, the inside of holding chamber 11 still is equipped with magnetism activity strip 3, the bottom of magnetism activity strip 3 adsorb in the bottom surface of holding chamber 11, the lateral part butt of magnetism activity strip 3 in the lateral wall of holding chamber 11 can follow the lateral wall of holding chamber 11 removes.

In this embodiment, the magnetic movable strip 3 is provided to facilitate the clamping of some PCBs with regular side shapes, such as square and rectangular PCBs.
