The first sealing device includes a fifth linear drive 24 arranged on the front side of the lifting frame, a third guide rail 25 arranged on the rear side of the lifting frame, a second cross bar 26 with a front end arranged on the fifth linear drive and a rear end arranged on the third guide rail, a glue injection head 27 arranged on the second cross bar at equal intervals, a glue injection branch pipe 28 connected to the glue injection head, a glue delivery pipe 29 connected to the glue injection branch pipe, and a glue pump 30 connected to the glue delivery pipe.

[0022] The exhaust sealing device includes a second cylinder 31 fixed on the left bracket with a piston rod facing vertically upward, a U-shaped frame 32 fixed on the piston rod of the second cylinder, a guide rod 33 arranged on the U-shaped frame and slidingly matched with the left bracket up and down, a second drilling device 34 arranged on the U-shaped frame, and a second sealing device 35 arranged on the U-shaped frame. The structure of the second drilling device is the same as that of the first drilling device, and the position of the second drilling device is higher than the first drilling device; the structure of the second sealing device is the same as that of the first sealing device.

[0023] In this embodiment, the first linear drive adopts a cylinder, and the second linear drive, the third linear drive, the fourth linear drive and the fifth linear drive adopt a linear motor. Of course, in different embodiments, the first linear drive, the second linear drive, the third linear drive, the fourth linear drive and the fifth linear drive may also adopt other forms.

[0024] In this embodiment, the gas injection head 18 includes a gas injection joint pipe 181, a nozzle pipe 182 arranged at the front end of the gas injection joint pipe for inserting into the drill hole, a rubber sealing head 183 arranged at the front end of the gas injection joint pipe for pressing on the end of the drill hole, and a first clamp 184 for connecting the gas injection joint pipe and the first cross bar.

[0025] In this embodiment, the glue injection head 27 includes a glue injection joint pipe 271, a sealing plaster plate 272 arranged at the front end of the glue injection joint pipe, and a second clamp 273 for connecting the glue injection joint pipe and the second cross bar.

[0026] In the specific implementation, a PLC control system can be used to control the working process of the insulating glass argon filling system. The specific working process is as follows:

[0027] The first step is to push the turnover rack with the insulating glass into between the gas injection sealing device and the exhaust sealing device so that the insulating glass contacts the front positioning baffle 3.

[0028] In the second step, under the control of the PLC control system, the first cylinder 7 drives the push plate 8 to push the insulating glass on the turnover frame to the left positioning baffle 5, thereby positioning and fixing the insulating glass.

[0029] In the third step, the PLC control system controls the first drilling device and the second drilling device to drill holes in the aluminum alloy frame of the insulating glass. During the drilling process, the second linear drive 11 drives the drilling machine to move left and right. After completing one hole, the third linear drive 13 drives the drilling machine to move forward a distance and then drill holes in the aluminum alloy frame of the next insulating glass. In this way, the air inlet holes are drilled on the lower right side of the aluminum alloy frame of each insulating glass, and the exhaust holes are drilled on the upper left side of the aluminum alloy frame of each insulating glass.

[0030] In the fourth step, the PLC control system controls the first linear actuator 10 to drive the lifting frame 9 to move downward so that the gas injection head 18 is aligned with the air inlet hole at the lower right side of the aluminum alloy frame, and then the PLC controls the fourth linear actuator 15 to drive the first crossbar 17 to move left so that the nozzle 182 of the gas injection head 18 is inserted into the air inlet hole, and then the PLC controls the electric gas valve 23 to open to allow argon gas to enter the insulating glass. After the argon gas enters, since the argon gas is heavier than air, the air in the insulating glass will be discharged from the exhaust port at the upper left side of the aluminum alloy frame.

[0031] The fifth step, after filling argon into the hollow glass, the PLC controls the fifth linear drive 24 of the first sealing device and the second sealing device to drive the second cross bar to move, so that the sealing smear plates 272 of the left and right sides of the glue injection heads are respectively against the edges of the hollow glass, and then controls the glue pump 30 to pump the sealant out of the container 36. At the same time, the PLC controls the first linear drive 10 to drive the lifting frame 9 to descend and controls the second cylinder 31 to drive the U-shaped frame 32 to descend. During the descent, the glue injection head discharges the sealant into the groove at the edge of the hollow glass, thereby sealing the air inlet and exhaust port on the aluminum alloy frame.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
