Automatic loading and unloading system for tin spraying procedure for PCBs

Abstract

The invention discloses an automatic loading and unloading system for a tin spraying procedure for PCBs. The system mainly comprises three parts including a tin spraying pretreatment part, a mechanical arm loading and unloading part and a tin spraying aftertreatment part; the tin spraying pretreatment part comprises a master control console, an automatic plate placing machine, tin spraying pretreatment equipment, a temporary storage machine, a PCB positioning device and a plate ejecting device; the mechanical arm loading and unloading part comprises a tin spraying machine, a mechanical arm, control equipment of the mechanical arm and a PCB fixture capable of being adjusted automatically; and the tin spraying aftertreatment part comprises a cooling floating bed, a sun type plate overturningmachine, tin spraying aftertreatment equipment and an automatic plate collecting machine. The whole system is arranged in the U shape. The system is a full-automatic loading and unloading system forthe tin spraying production link of the PCBs, but the actions of equipment can be controlled separately by the aid of the master control console. The system has the beneficial effects as follows: thesystem can replace manpower to complete working in the tin spraying link, so that the production efficiency can be improved, and harm caused by working environments to human bodies can also be avoided.

Description

Technical field [0001] The invention relates to a PCB board production equipment, in particular to an automatic loading and unloading system for the PCB board tin spraying process. Background technique [0002] The tin spraying process is an essential part of the PCB production process. The traditional production method of the spray tin process is to manually place the PCB board on the fixture of the spray tin machine, and then the spray tin machine completes the spray tin operation, and finally the PCB board is manually taken out; now, a mechanical arm is used for spraying The tin machine has carried out the operation of placing and removing the plate, but currently the spraying machine is usually equipped with two mechanical arms, one is responsible for feeding, the other is responsible for unloading, and in the actual production process, for the same machine For the loading and unloading of the tin spraying machine, the operation waiting time of each robotic arm is too long, ...

Problems solved by technology

The traditional production method of the tin spraying process is to manually place the PCB board on the fixture of the tin spraying machine, then the tin spraying machine completes the tin spraying operation, and finally the PCB board is taken out manually; now the mechanical arm is used for spraying The tin machine has carried out the operation of placing and removing the board, but at present, the tin spraying machine is usually equipped with two robotic arms, one is responsible for loading and the other is responsible for unloading, and in the actual production process, for the same For the loading and unloading of the tin spraying machine, the waiting time for the operation of each robot arm is too long, and the operating efficiency is low, so it is very uneconomical; moreover, the jig configured for the robot arm has only one size, and its adjustable The range is very small and cannot adapt to the production of PCB boards of different sizes. If you need to produce PCB boards of different sizes, you must replace the mechanical arm fixtures of different sizes; the current situation not only increases the cost of production equipment, but also affects The continuity of production reduces the efficiency of production
