Vertical convection thermal system MSTX-600
The MSTX-600 vertical convection thermal system is specially designed to
solve the back-end process and bottleneck
in the operating process. This
automatic curing system consists of
seven parts: PCB input device (pallet),
lifting device, transfer device, PCB output device
device, heating device, width adjustment device
width adjustment device, and control system.
The control system is a self-developed
PLC, and the drive motor is a stepper motor.
and servomotor of a well-known brand. Friendly touch screen interface makes the whole systemSystem precise, easy to operate, reliableperformance, continuous curing processand adjustable curing time, making it the bestbest choice for the curing process.

System workflow
When the device is in operation, the warm
Air flow continuously directed into the chamber.
Once the temperature has reached the set value,
the product (pallet) is placed in the plate layer on the
the product (pallet) is placed in the plate layer on the side, the lifting device
layer upwards until it reaches the transition layer. The
transfer device sends the product to the
exit side, and then the lifting device moves
the product layer by layer downwards
and sends it to the exit level. The exit device sends
products out of the oven; the work cycle
continues to complete the process.
Features of the MSTX-600 Vertical Convection Thermal System
HEATING DEVICE
The motor drives the wind wheel in the heating box to supply the inside of the stove with heat. The hot air flows through the air ducts on both sides of the appliance and enters the chamber through the grille plate, where it forms the vortex of the air flow, which is sucked into the external outlet and finally forms a circulation flow in the chamber.
CONTROL OF THE PRINTED CIRCUIT BOARD FEEDER
The speed of the stepper motor is controlled by the main PLC. A photoelectric sensor controls the starting device for PCB centering. A photoelectric limit sensor detects whether the position of the inserted PCB is correct. If not, operation of the system is interrupted. A fiber optic sensor installed in the chamber is used to determine whether the PCB is in place or not.
CONTROL OF THE LIFTING DEVICE
The components of the lifting mechanism are driven by a servomotor which is connected to the main controller (PLC). The speed of movement and the positioning of the hanger in the chamber are controlled according to the preset program. The fiber for detecting the stroke limit is installed at the lower end of the output. If the output layer falls beyond the detection limit, operation is interrupted.
PRINTED CIRCUIT BOARD OUTPUT DEVICE
Two parallel chains are installed at the side exit and a pressure device is attached to both chains. The chain is driven by the installed sprocket. A stepper motor is installed below the outlet, which drives the two chain wheels and transports the product from the outlet layers to the connection device outside the chamber. The output is driven by a stepper motor whose speed is controlled by a PLC.
