Description

Technical Field

[0001] This application relates to the field of manufacturing or processing of semiconductor devices, and particularly to a fully automatic mounting, ultraviolet pre-curing, curing device and its method. Background Art

[0002] In the field of electronic component mounting, the existing processes respectively complete dispensing, mounting, pre-curing, and curing operations through independent devices. When the substrate is transferred between each process, the uncured colloid is vulnerable to mechanical vibration or external disturbance due to the lack of immediate fixing ability, resulting in displacement deviation of the components on the substrate and affecting the mounting accuracy. At the same time, the devices used in each link are independent of each other, the production line is relatively long, and the conveying distance on the production line is far. This not only leads to low production efficiency but also increases the risk of component offset on the substrate. Summary of the Invention

[0003] In order to solve the problem that the components mounted on the substrate are prone to displacement deviation during uncuring, resulting in reduced mounting accuracy in the prior art, this application provides a fully automatic mounting, ultraviolet pre-curing, curing device. The specific solution is as follows: A fully automatic mounting, ultraviolet pre-curing, curing device, including a working platform. Along the Y-axis direction on the upper side of the working platform, a pre-curing feeding mechanism, a curing discharging mechanism, and a discharging mechanism are sequentially arranged. The pre-curing feeding mechanism can move along the X-axis direction and the Y-axis direction respectively. After the pre-curing feeding mechanism transports the carrier with the substrate to the pre-curing area and sequentially performs dispensing operation, mounting operation, and pre-curing operation on the substrate on the carrier, the pre-curing feeding mechanism can move to the curing discharging mechanism and transfer the carrier to the curing discharging mechanism. The curing discharging mechanism transfers the carrier to the curing area, and after curing the substrate on the carrier, the curing discharging mechanism transfers the carrier to the discharging mechanism. An X-axis guide rail is fixedly arranged on the upper side of the working platform. A dispensing mechanism and a suction nozzle mechanism are installed on the X-axis guide rail. The dispensing mechanism and the suction nozzle mechanism are respectively driven by the X-axis guide rail to move along the X-axis direction.
