PCB buffering and locating hot-pressing fixture

Abstract

The invention discloses a PCB buffering and locating hot-pressing fixture. The PCB buffering and locating hot-pressing fixture comprises a hot-pressing table and an air cylinder, and is characterized in that a carrier plate is arranged on the top of the hot-pressing table, a rack is arranged above the hot-pressing table, guide pillars are arranged between the rack and the hot-pressing table, the air cylinder is arranged in the rack, the bottom of an air cylinder rod of the air cylinder is connected with a pressing plate, the pressing plate penetrates through the guide pillars, a buffering backing plate is arranged at the bottom of the pressing plate, a heating plate is arranged below the buffering backing plate, heating sheets are arranged in the heating plate, locating pins are arranged on two sides of the bottom of the pressing plate respectively, two locating bases are correspondingly arranged on the hot-pressing table, and blind holes are formed in the locating bases. According to the PCB buffering and locating hot-pressing fixture, the problems that a PCB can be pressed to damage easily by the pressing plate in the pressing process of the pressing plate because the speed is too high, and the pressing plate can not be aligned to a heating point well because a hot-pressing device is not provided with a locating system are solved; the PCB buffering and locating hot-pressing fixture is fast in location, and can guarantee correctness of machining positions and protect a hot-pressing plate.

Description

technical field [0001] The invention relates to a welding device, in particular to a PCB board buffer positioning hot-press fixture. Background technique [0002] The Chinese name of PCB board is printed circuit board, also known as printed circuit board and printed circuit board. It is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. Some electronic parts need to be soldered on the PCB board. At present, the hot pressing equipment does not have a positioning system. After the pressing plate drives the heating plate to move, the heating plate may not be aligned with the heating point, resulting in low heating accuracy, unable to meet the needs of production and processing, resulting in a large number of defects. product production. At the same time, the heating plate may be easily crushed by the pre...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the heating plate in the prior art may be easily crushed by the pressing plate due to the excessive speed during the pressing process, resulting in damage to the equipment. At the same time, the current hot pressing equipment does not have a positioning system, and the hot pressing plate cannot be well aligned with the heating point. , leading to the problem of low heating accuracy, the present invention provides a PCB board buffer positioning hot pressing fixture with simple structure, convenient use, fast positioning, correct processing position, and protection of the hot pressing board
