At present, the SMT surface mount technology based on a PCB processing series flow is widely used in the electronic assembly industry, a surface mount needs to be performed on an SMP connector (hereinafter referred to as a connector) in a micro-assembly process flow, and the current main process and respective application conditions are as follows:

manual patching: the method is characterized in that a worker directly operates to complete a chip mounting process, and is generally applied to the conditions of small batch, low chip mounting position precision requirement and high operation flexibility requirement, but the efficiency is low and the precision is not high;

mounting a piece: the relative position relation between a mounted device and a substrate is ensured through a tool, and the tool is generally applied to the condition of high mounting precision, but the tool is generally complex, increases the risk of damage to a connector when the tool is taken out after surface mounting, and has longer design and production period and higher cost;

machine patching: automatic chip mounting is carried out through a chip mounter, the chip mounting precision is high, the operation is convenient, the efficiency is high, but the application range is limited due to poor interchangeability of the machine and the connector.

Disclosure of Invention

The utility model aims to solve the defects of low efficiency and low precision of manual surface mounting, and avoid the problems of inconvenient operation (difficult tool taking out) and extra tool preparation period and cost caused by designing complex tools to carry out high-precision surface mounting on a connector.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides an elastic chuck for automatic paster of connector, including weight shell, connector body and dabber, the fixed cover of weight shell connects on the surface of dabber, the bottom of weight shell is seted up flutedly with interior wall connection's position department, the top of the inner wall of recess is rotated and is connected with the stripper plate, the position that one side that the dabber was kept away from to the stripper plate is close to the bottom is provided with the spring, the other end of spring and the side fixed connection of recess inner wall, the lower surface and the side surface hookup location department of dabber have seted up the rotation groove, the top of rotation inslot wall is rotated and is connected with the buckle, the side fixedly connected with extension spring of buckle, the other end of extension spring and the hookup location fixed connection at the side of rotation inslot wall and top, the connector body passes through the buckle activity card in the below of dabber.

Preferably: the rotation groove and the groove are correspondingly arranged, the number of the rotation groove and the number of the groove are eight, and the eight rotation grooves and the eight grooves are distributed in an annular array mode by taking the axis of the mandrel as an array center.

Preferably: the bottom of buckle and the fixed connection in position of connector body contact have the protection piece.

Preferably: one end of the spring close to the extrusion plate is movably connected with the extrusion plate.

Preferably: the mandrel is made of a material with high elasticity, small elastic hysteresis and good stability.

Due to the adoption of the technical scheme, the utility model has the following advantages:

through setting up weight shell, buckle and extension spring, the bottom of holding the weight shell through the last sucking disc of chip mounter, then remove the weight shell and drive dabber and buckle and remove the top of connector body together, then move downwards alright press from both sides the connector body through the buckle and get, then paste the position of adorning the correspondence on external base plate, it is efficient and the precision height of paster to have reached, simple step reduces the effect of the paster operation degree of difficulty.
