Description

Technical Field

[0001] The utility model relates to the field of auxiliary devices for reflow soldering furnaces, in particular to a lifting device for reflow soldering furnaces. Background Art

[0002] Reflow ovens usually require a lifting device to control their height for welding or other processing. This device can be controlled manually or automatically, and is usually driven by a hydraulic system or a pneumatic system. Manual lifting devices are usually driven by a hydraulic system that controls the flow of oil through a hydraulic valve. The hydraulic valve can be opened or closed to control the flow of oil, thereby controlling the up and down movement of the hydraulic cylinder. Usually, manual lifting devices require an operator to control, and the operator controls the up and down movement of the hydraulic cylinder by manipulating the hydraulic valve; automatic lifting devices are usually driven by a pneumatic system that controls the flow of air through a pneumatic valve. The pneumatic valve can be opened or closed to control the size of the airflow, thereby controlling the up and down movement of the hydraulic cylinder. Automatic lifting devices can usually be set up on the control cabinet, and the operator can control it through the operation panel or remote control.

[0003] The existing manually-operated lifting device for the reflow soldering furnace usually uses multiple telescopic cylinders to drive the top to open to one side when in use, so that when the internal circuit board has a problem, it can be taken out in time to reduce cost losses. However, the cylinder itself does not have a self-locking function. During the movement of the lifting mechanism, unexpected shutdown or too fast descent may occur, causing damage to the machine or personnel.
