Technical Field

[0001] The utility model relates to the technical field of dispensing machine devices, and more specifically, the utility model relates to a dispensing machine for circuit board processing. Background Art

[0002] A circuit board dispensing machine is a device for applying special glue to circuit boards, which can cover a layer of special glue on electronic components on the circuit board and play a role in protecting the electronic components from water and insulation. Traditional circuit board dispensing machines are composed of components such as a glue bucket, a dispensing machine body, an orientation control device, a cylinder, and a glue gun. The position of the glue gun is controlled by movable components such as an electric slide rail and applied to the components on the circuit board. There are two structures for dispensing machines with replaceable glue gun heads. The first type of dispensing machine has two glue gun heads of different specifications arranged side by side, and this type of dispensing machine cannot rotate the angle. The second type of dispensing machine has two glue guns with independently controlled orientations, and this type of dispensing machine can rotate the angle, but has more structures and a higher production cost of the device, which brings inconvenience to users. To solve the deficiencies of the existing technology, we propose a dispensing machine for circuit board processing. Content of the Utility Model

[0006] The gun-changing component includes a slider, the slider is arranged on one side of the orientation control device, and the orientation control device can control the slider to slide up and down, left and right, and rotate. A hollow tube is fixedly installed on the outer surface of one side of the slider, a motor is fixedly installed on the inner wall of the slider, one end of the rotating shaft of the motor is fixedly connected with a first gear, the outer wall of the hollow tube is rotatably connected with a second gear, the first gear meshes with the second gear, a rotating frame is fixedly connected to the outer surface of one side of the second gear, a first glue gun is fixedly connected to the top surface of the rotating frame, a second glue gun is fixedly connected to the bottom surface of the rotating frame, and a glue outlet is opened on the outer wall of the lower side of the hollow tube.

[0007] Wherein, one end of the glue delivery pipe of the glue bucket is fixedly connected to the outer wall of the hollow pipe, and its function is to allow the glue to flow through the glue delivery pipe and then flow into the interior of the hollow pipe.

[0008] Wherein, through holes are formed on the outer surfaces of both sides of the rotating frame, and the two through holes are located on one side of the glue gun one and the glue gun two, and the purpose is to enable the glue in the hollow pipe to flow into the glue gun one or the glue gun two through the through holes.

[0009] Wherein, the glue discharging assembly includes an electric push rod and a cylinder. The electric push rod is fixedly installed on the upper outer surface of the dispensing machine body. The cylinder is fixedly installed on the upper outer surface of the dispensing machine body. The cylinder is located on one side of the electric push rod. One end of the push rod of the electric push rod is fixedly connected to a piston. The piston is slidably connected to the inner wall of the cylinder. A spherical one-way valve one is fixedly installed on the outer wall of the cylinder for the purpose of unidirectionally sucking air.

[0013] The present utility model is provided with a gun changing assembly, including a motor and a rotating frame. When the motor is started, the gear one drives the gear two to rotate, so that the rotating frame rotates 180 degrees. At this time, the glue gun one and the glue gun two exchange positions, and the glue gun one is located at the lower working position. The glue flows from the glue delivery pipe of the glue bucket into the interior of the hollow pipe.

When it is necessary to process a circuit board of another specification, the motor is started to rotate the rotating frame 180 degrees, and the glue gun two can be adjusted to the working position. With the above structure, by driving the rotating frame to rotate by the motor, the switching between the glue gun one and the glue gun two is realized. When rotating the dispensing angle, it is not necessary to set two glue guns with independently controlled azimuths. The structure is relatively simple, the production cost of the device is saved, it is convenient for the user to perform dispensing processing on the circuit board from different angles, and the flexibility of the device is improved;

When the glue gun needs to be cleaned, the motor is started to rotate the glue gun 1 or the glue gun 2 to the horizontal position, and the orientation control device is started to slide the gun head above the waste box. Then the electric push rod is started, which can continuously suck air from the spherical one-way valve 1, and finally the air enters the air outlet from the spherical one-way valve 2, so as to discharge the glue inside the glue gun 1 or the glue gun 2 into the waste box. With the above structure, the piston is pushed by the electric push rod to continuously blow air into the air chamber, so that the glue inside the glue gun 1 or the glue gun 2 can be discharged, avoiding the solidification of the glue accumulated inside the glue gun, saving the time for cleaning the glue gun, facilitating the user to clean the glue gun, and improving the practicability of the device.
