[0097] The working principle of the present invention is as follows:

[0098] The lower shell vibration loading plate is a vibration plate, which is used to vibrate the lower shell onto the first guide rail. After passing through the first guide rail, the lower shell will move to the first material transfer block. During the movement, the first visual inspection mechanism will take pictures of the lower shell and perform visual inspection (the control system will record the excellent situation of the product). The first visual inspection mechanism is generally equipped with a fill light. The first material transfer block moves to the bottom of the first clamping cylinder under the action of the first cylinder. The first clamping cylinder can move up and down through the linear motor and can move forward and backward through the first linear motor. If the lower shell does not pass the inspection in the previous inspection, the first clamping cylinder will drop it when passing through the first unloading port. If it passes the inspection, it will be placed on the welding station. Then the second turntable rotates one eighth to move the welding station where the lower shell is installed to the next position.

[0099] The filter feeding mechanism is a rotating upper plate mechanism. The filter is placed in the filter installation cylinder (usually eight), and the first rotating motor at the bottom rotates for feeding. The specific process is as follows: the first rotating motor rotates one-eighth of a turn, and the vertical linear motor drives the suction cup mechanism to move down, sucking up a piece of filter paper, and then moves to the welding station through the third linear motor, and then puts the filter paper into the lower shell. The height detector is used to detect the height of the filter paper, so that the height of the top can be known from below.

[0100] The upper shell vibrating loading tray and the lower shell vibrating loading tray, as well as the specific loading principles are the same, and the technology can be understood accordingly.

[0101] The ultrasonic welding machine is an existing mature mechanism, which is used for ultrasonic heat-melting welding connection of the upper shell and the lower shell.

[0102] The air tightness testing mechanism is used to test the air tightness of the finished product after welding, and the specific results are fed back on the air tightness testing instrument.

[0103] The flow detection mechanism is used to detect the flow rate of the finished product after welding, and the specific results are fed back on the flow detector.

[0104] The function of the first linear motor is to move the finished products after inspection, and move the qualified ones to the qualified finished product box, and the unqualified ones to the unqualified finished product box.

[0105] The control system adopts a PLC control system to control the operation of all the aforementioned cylinders and motors.

[0106] The present invention has at least the following advantages:

[0107] The device can realize fully automatic feeding of the filter screen, can perform automatic visual inspection on the two shells of the filter screen, can perform air tightness and flow inspection on the finished product after electric welding, and realizes fully automatic inspection and production of the filter.

[0108] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
