DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a vacuum pumping device for producing vacuum glass provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the structure of the sliding groove part shown; Figure 3 for Figure 1 The schematic diagram of the glue gun part structure shown; Figure 4 for Figure 1The schematic diagram of the partial structure of the sliding block shown is a vacuum pumping device for producing vacuum glass, comprising: a base 1, a vacuum assembly 2 is arranged on the front side of the top of the base 1, and a sealing assembly 3 is arranged on the top of the base 1 and on the left side of the vacuum assembly 2;

[0024] The vacuum assembly 2 includes a conveyor belt 21 disposed on the top of the base 1, a glass plate 22 is placed on the top of the conveyor belt 21, a sliding groove 23 is disposed on the top of the base 1, a vacuum pump 24 is disposed inside the sliding groove 23 and can slide back and forth, and the vacuum pipe on the back of the vacuum pump 24 is a hard cone;

[0025] By placing the glass plate 22 that needs to be evacuated on the conveyor belt 21, and coordinating the timed transmission of the conveyor belt 21, when the exhaust hole of the glass plate 22 is parallel to the exhaust pipe of the vacuum pump 24, the conical exhaust pipe is inserted into the exhaust hole by extending the output end of the telescopic cylinder 25, and the vacuum is evacuated by the vacuum pump 24.

[0026] The glue sealing assembly 3 includes a placement groove 31 arranged on the left side of the top of the base 1, and a glue gun 32 is arranged inside the placement groove 31. The glue outlet of the glue gun 32 is on the same horizontal line as the air extraction hole of the glass plate 22. A rotating rod 33 is arranged on the inner side of the placement groove 31 so as to be rotatable laterally. A trigger block 34 is arranged on the peripheral side of the rotating rod 33 and at the trigger of the glue gun 32.

[0027] After the vacuuming is completed, the conveyor belt 21 continues to transport, and the output end of the first motor 35 rotates to drive the rotating rod 33 to rotate. The rotating rod 33 rotates and drives the trigger block 34 to rotate along its axis. When it abuts against the trigger of the glue gun 32, it continues to rotate, so that the glue gun 32 pushes the glass glue to extrude, and cooperates with the moving glass plate 22 to close its open vacuum holes, thereby shortening the closing time and improving the extraction effect of the vacuum glass.

[0028] A first motor 35 for driving the rotating rod 33 to rotate is provided on the inner side of the base 1 and on the left side of the placement slot 31. The left end of the rotating rod 33 passes through the inner side of the placement slot 31 and extends to the inner side of the base 1. The output end on the right side of the first motor 35 is fixedly connected to the left end of the rotating rod 33.

[0029] The vacuum assembly 2 further includes a telescopic cylinder 25 disposed inside the sliding groove 23 , and a telescopic end on the back side of the telescopic cylinder 25 is fixedly connected to the front side of the vacuum pump 24 .

[0030] Two groups of fixing rods 4 are arranged at the rear side of the top of the base 1 , and sliding blocks 5 are arranged around the sides of the two groups of fixing rods 4 so as to slide up and down along the height direction thereof, and two air pumps 6 are arranged on the left and right sides of the front of the sliding blocks 5 .

[0031] When the conveyor belt 21 transports the glass plate 22 and stops for the first time, in order to avoid displacement of the glass plate 22 caused by the vacuum pump 24 during the vacuuming process, the sliding block 5 is driven by two electric telescopic rods 8 to move downward on the peripheral side of the fixed rod 4, so that the two suction cups 7 are tightly attached to the top of the glass plate 22.

The output ends of the tops of the two electric telescopic rods 8 are fixedly connected to the two sides of the sliding block 5.

[0033] After the suction cup 7 is in close contact, the rotation of the output end of the second motor 12 drives the two racks 10 to move relative to each other, and then drives the two piston rods 9 to move relative to each other. The movement of the piston rods 9 makes the internal air pressure of the vacuum cylinder 6 lower than that of the outside, and then the two suction cups 7 firmly hold the glass plate 22, and the fixing effect is good.

[0034] A piston rod 9 is provided on the opposite side of the two vacuum cylinders 6 so as to slide left and right. A rack 10 is provided on the opposite side of the two piston rods 9.

[0035] The working principle of a vacuum pumping device for producing vacuum glass provided by the utility model is as follows:

[0036] Step 1: When in use, place the punched glass plate 22 on the conveyor belt 21, and transport it to the left through the conveyor belt 21. After arriving at the set location, the two electric telescopic rods 8 drive the sliding block 5 to move downward on the peripheral side of the fixed rod 4, so that the two suction cups 7 are closely attached to the top of the glass plate 22. At this time, the rotation of the output end of the second motor 12 drives the relative movement of the two racks 10, and then drives the relative movement of the two piston rods 9. The movement of the piston rod 9 makes the internal air pressure of the vacuum cylinder 6 lower than that of the outside, and then the two suction cups 7 firmly suck the glass plate 22 to prevent it from shifting during vacuuming;

[0037] Step 2: The conical exhaust pipe is inserted into the exhaust hole by extending the output end of the telescopic cylinder 25, and the vacuum is pumped through the vacuum pump 24. After the exhaust is completed, the conveyor belt 21 continues to convey. At this time, the output end of the first motor 35 rotates to drive the rotation of the rotating rod 33. The rotation of the rotating rod 33 drives the trigger block 34 to rotate along its axis. When it abuts the trigger of the glue gun 32, it continues to rotate, so that the glue gun 32 pushes the glass glue to extrude, and cooperates with the moving glass plate 22 to close the open exhaust hole, thereby shortening the closing time and improving the extraction effect of the vacuum glass.

[0038] Compared with the related art, the vacuum pumping device for producing vacuum glass provided by the utility model has the following beneficial effects:

[0039] The extension of the output end of the telescopic cylinder 25 drives the tapered exhaust pipe to be inserted into the exhaust hole, and the vacuum pump 24 exhausts the air. After the exhaust is completed, the conveyor belt 21 continues to convey the air. At this time, the output end of the first motor 35 rotates to drive the rotation of the rotating rod 33. The rotation of the rotating rod 33 drives the trigger block 34 to rotate along its axis. When it abuts the trigger of the glue gun 32, it continues to rotate, so that the glue gun 32 pushes the glass glue to extrude, and cooperates with the moving glass plate 22 to close the open exhaust hole, thereby shortening the closing time and improving the extraction effect of the vacuum glass.
