Improved structure of PCB hot air seam sealing machine

Abstract

The invention discloses an improved structure of a PCB hot air seam sealing machine. The improved structure comprises a machine frame. A press roller unit is located between the feeding end and the discharging end of the machine frame, the press roller unit is composed at least one pair of press rollers, each pair of press rollers are vertically arranged and can rotate synchronously and reversely, a switch key is located on the machine frame, and the switch key comprises a starting switch and an emergency stop switch. The improved structure further comprises a stroke switch and a protection part, wherein the stroke switch is arranged on the machine frame and in parallel connection with the emergency stop switch, the protection part is detachably arranged on the machine frame and can shield the two sides of the press roller unit in the PCB conveying direction, and the protection part can trigger a mechanical touch point on the stroke switch. When an operator needs to examine the PCB processing situation or replace materials in the hot air seam sealing machine, the protection part must be taken down at first. Thus, the stroke switch is triggered, the hot air seam sealing machine is powered off and stops rotating, irregularity accidents caused by the operator are avoided, and the safety guarantee of the operator is effectively improved.

Description

technical field [0001] The invention relates to the technical field of a PCB glue pressing machine, and specifically provides an improved structure of a PCB glue pressing machine. Background technique [0002] In the printed circuit board (PCB) manufacturing process, the glue press is mainly used to cover the surface of the PCB board with blue glue seamlessly and tightly, and to make the blue glue and the surface of the PCB board firmly bonded. However, in the actual production process, when the operator checks the processing status of the PCB board or replaces the materials in the gluing machine or handles production failures, the operator often directly reaches out to the pressing roller of the gluing machine due to negligence. This will produce the phenomenon of pinching the operator, resulting in a safety accident. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides an improved structure of a PCB gluing m...
