Description
Technical Field
The utility model relates to a welding technology field of circuit board, especially a rosin output device of circuit board welding machine.
Background
Rosin is a commonly used flux and is used in most soldering processes.
When a circuit board welding machine is used for welding a circuit board, rosin is also needed to be used as the soldering flux. The rosin is placed in a closed rosin tank, a rosin output pipe is arranged on one side of the rosin tank, the top of the rosin tank is connected with an external air pump or a high-pressure air chamber through an air inlet pipe, and the rosin is pressed out of the rosin output pipe through high-pressure air introduced through the air inlet pipe. In the prior art, the air valve of a manual switch is mostly adopted to control the on and off of the air inlet pipe, the air valve is in a normally open state in the normal working process of the circuit board welding machine, when rosin is about to be used up, the air valve needs to be closed, then the rosin tank is opened to add the rosin, the rosin tank is closed after the rosin is filled, and then the air valve is opened. In the actual production process, a lot of workers can forget to open the air valve again after adding rosin for the rosin jar, if open circuit board welding machine and come the welding circuit board under this condition, then can lead to the problem that welding quality is not up to standard because of there is not rosin to help the welding.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing a rosin output device of circuit board welding machine, it can control the logical and close of intake pipe automatically, avoids forgetting the phenomenon appearance of opening the pneumatic valve.
The utility model discloses a solve its technical problem and the technical scheme who adopts is:
the utility model provides a rosin output device of circuit board welding machine, its includes the rosin jar, the rosin jar on be provided with intake pipe and rosin output tube, the other end of intake pipe be connected with high pressurized air source, the rosin jar sets up the inside at the circuit board welding machine, be provided with the cabinet door that can open and shut on the circuit board welding machine, intake-tube connection have control its logical and closed solenoid valve, be provided with on the cabinet door and control solenoid valve and open when the cabinet door is closed and the inductive switch that control solenoid valve closed when the cabinet door is opened.
Preferably, the rosin tank is fixed on the inner side of the cabinet door.
Preferably, the cabinet door is a vertical hinged door capable of being opened outwards, and the air inlet pipe comprises a first hose connected between the electromagnetic valve and the rosin tank and a second hose connected between the electromagnetic valve and the high-pressure air source.
Preferably, the air inlet pipe is connected with a manual air valve which can control the opening and closing of the air inlet pipe.
The utility model has the advantages that: the utility model discloses a switching on and off of action automatic control intake pipe of switch door can avoid effectively leading to the not up to standard phenomenon of product quality to take place because of forgetting to open manual pneumatic valve.
Drawings
FIG. 1 is a schematic view of the working principle of the present invention;
fig. 2 is a schematic diagram of the position relationship between the box door and the rosin tank when the box door is opened.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Referring to fig. 1 and 2, the embodiment of the utility model provides a rosin output device of circuit board welding machine, it includes rosin jar 1, be provided with intake pipe 2 and rosin output tube 3 on the rosin jar 1, the other end of intake pipe 2 is connected with high pressurized air source 4, high pressurized air source 4 is plenum chamber or air pump, rosin jar 1 sets up the inside at circuit board welding machine 5, be provided with the quick-witted chamber door 51 that can open and shut on the circuit board welding machine 5, intake pipe 2 is connected with its solenoid valve 6 that leads to and close of control, be provided with inductive switch 7 on the quick-witted chamber door 51, inductive switch 7 is connected with solenoid valve 6 electricity, make inductive switch 7 can control solenoid valve 6 open when quick-witted chamber door 51 is closed, and control solenoid valve 6 closes when quick-witted chamber. This inductive switch 7 is a conventional electrical component, and its specific structure and operation principle are not specifically described herein.
Because the rosin tank 1 is arranged inside the circuit board welding machine 5, when rosin is added into the rosin tank 1, the cabinet door 51 needs to be opened, the cabinet door 51 is opened, the inductive switch 7 is touched, the electromagnetic valve 6 is closed, and at the moment, the gas path of the gas inlet pipe 2 is disconnected; after the rosin is added, the cabinet door 51 is closed, the inductive switch 7 is touched again while the door is closed, the electromagnetic valve 6 is opened, and the air path of the air inlet pipe 2 is conducted again at the moment. The utility model discloses in the action automatic control intake pipe 2 through the switch door expert and disconnected, can avoid effectively leading to the not up to standard phenomenon of product quality to take place because of forgetting to open manual pneumatic valve 8.
In this embodiment, the air inlet pipe 2 comprises a first hose 21 connected between the solenoid valve 6 and the rosin tank 1 and a second hose 22 connected between the solenoid valve 6 and the high pressure air source 4.
Referring to fig. 2, as the utility model discloses further improve, the vertical hinged door that casing door 51 is can outwards open, and casing door 51's inboard is fixed and is provided with support frame 52, and rosin jar 1 fixed mounting is on this support frame 52. With such a structure, after the cabinet door 51 is opened, the rosin tank 1 located inside the cabinet door 51 is exposed outside the circuit board welding machine 5, so that rosin can be added thereto.
As the utility model discloses improve still further, intake pipe 2 is last and be connected with and to control its logical manual pneumatic valve 8 that closes. The manual air valve 8 can be used as a standby valve when the electromagnetic valve 6 or the inductive switch 7 fails; when the device is not used for a long time, the device can be closed to be used as a safety valve.
The above is only the preferred embodiment of the present invention, as long as the technical solution of the purpose of the present invention is realized by the substantially same means, all belong to the protection scope of the present invention.
