fig. 2 is a schematic view of an appearance structure of the PCB oven of the present invention.

In the figure: the device comprises a shell, 11, a plate feeding opening, 111, a guide plate, 12, a plate discharging opening, 13, a positioning rod, 14, an action sensor, 2, a heating device, 3, a pushing coil pipe, 31, a pushing motor, 4 and an overhauling panel.

Detailed Description

In order to further understand the features and technical means of the present invention and achieve the specific objects and functions, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

A PCB baking box comprises a shell 1, a heating device 2 and a pushing coil pipe 3. Heating device 2 installs in the inside bottom of casing 1, propelling movement motor 31 is installed at 1 both ends of casing, propelling movement coil pipe 3 arranges inside casing 1, and propelling movement coil pipe 3 both ends are connected to the output shaft of propelling movement motor 31 respectively. Heating device 2 is used for toasting the PCB board, and propelling movement coil pipe 3 is rotatory in the drive of propelling movement motor 31 output shaft, and then promotes the PCB board along 3 axial slow movements of propelling movement coil pipe.

A positioning rod 13 is arranged in the shell 1, the positioning rod 13 is positioned below the pushing coil pipe 3, a board throwing port 11 and a board outlet port 12 are arranged on the wall surface of the shell 1, and a guide wall surface with the same height as the PCB is arranged on the inner side of the board outlet port 12. The locating lever 13 is used for providing the bottom for the PCB board spacing, treats that the PCB board moves to 3 ends of propelling movement coil pipe and contacts to the output shaft of propelling movement motor 31, and the PCB board is because receiving the hindrance and no longer continuing along 3 axial motion of propelling movement coil pipe, and is then promoted by propelling movement coil pipe 3 to radial, finally is seen off by play board mouth 12. The guide wall surface inside the board outlet 12 serves to prevent the PCB board from falling without leaning.

Preferably, the housing 1 is provided with a motion sensor 14 outside the outlet 12. After action sensor 14 detects that there is the PCB board to toast and accomplish the product in a board mouth 12 department, will stop the operation of propelling movement motor 31, take away the PCB board of a board mouth 12 department until having the staff, avoid propelling movement motor 31 to continue the operation and the staff in time not get the board and lead to the PCB board gathering at a board mouth 12 and propelling movement coil pipe 3 end, hinder propelling movement coil pipe 3 motion, and then reverse damage propelling movement motor 31.

Preferably, the housing 1 is provided with a guide plate 111 inside the panel insertion opening 11. So set up, make the staff be convenient for align propelling movement coil pipe 3 when adding new PCB board to casing 1.

Preferably, the housing 1 is provided with an access panel 4 which can be opened and closed with respect to the housing 1. So set up, make things convenient for the staff to carry out the maintenance or the change of parts such as propelling movement coil pipe 3, heating device 2.

Preferably, the access panel 4 is provided with a glass viewing window. So set up, the staff can observe the motion state of propelling movement coil pipe 3 and PCB board, is convenient for in time discover the trouble and shut down the maintenance.

The working process of the utility model is explained by combining the preferred examples: propelling movement motor 31 starts, slowly rotate through its output shaft drive propelling movement coil pipe 3, the staff puts into the PCB board of waiting to toast by throwing board mouth 11, the PCB board is under the spacing of locating lever 13, it advances slowly to be promoted by propelling movement coil pipe 3, receive the toast of heating device 2 in the oven, reach the 3 opposite side ends of propelling movement coil pipe when the PCB board, no longer advance under this side propelling movement motor 31's output shaft hinders, and then it promotes to propelling movement coil pipe 3 radial movement to be promoted by propelling movement coil pipe 3, finally send out by play board mouth 12. After action sensor 14 detects that there is the PCB board to toast and accomplish the product in a board mouth 12 department, will stop the operation of propelling movement motor 31, take away the PCB board of a board mouth 12 department until having the staff, avoid propelling movement motor 31 to continue the operation and the staff in time not get the board and lead to the PCB board gathering at a board mouth 12 and propelling movement coil pipe 3 end, hinder propelling movement coil pipe 3 motion, and then reverse damage propelling movement motor 31.
