[0068] S3, bonding the frame 120 to the four sides of the insulating glass 110 to form the door body 100;

[0069] S4, when the door body 100 moves to the first centering assembly device 210, the carrier plate 211 rises, so that the door body 100 is placed on the carrier plate 211 of the first centering assembly device 210, and the multiple clamping blocks 212 on the carrier plate 211 clamp the door body 100 around for a preset time length, so that the door body 100 can be shaped. The preset time here is preferably 10s-15s. After that, the clamping blocks 212 are released, the carrier plate 211 descends, and the door body 100 falls on the conveying device 10. The door body 100 is continuously conveyed by the conveying device 10, and at this time, the first connecting hole 121 is set downward.

[0070] The above step S3 is specifically as follows: the insulating glass 110 moves to the first centering assembly device 210, the carrying plate 211 rises, and the push rod 23 rises to the first position to lift the insulating glass 110 from the conveying device 10. The lifted insulating glass 110 is located above the clamping block 212. At this time, the operator bonds the frame 120 around the insulating glass 110 to form the door body 100. After the bonding is completed, the push rod 23 descends to the second position, and the door body 100 falls on the carrying plate 211 of the first centering assembly device 210. In other embodiments, step S3 can also be completed manually on the conveying device 10.

[0071] S5, the door body 100 moves to the first flipping device 310, and the first flipping device 310 drives the door body 100 to flip 180 degrees so that the first connecting hole 121 is set upward, so as to facilitate the subsequent connection between the corner code 130 and the frame 120.

[0072] S6. Use fasteners to connect the first connection hole 121 and the second connection hole 131, so that the multiple frames 120 are connected as a whole through the corner code 130. This step can be performed at the second centering assembly device 220. When the door body 100 moves to the top of the second centering assembly device 220, the door body 100 is placed on the bearing plate 211 of the second centering assembly device 220, and the multiple clamping blocks 212 on the bearing plate 211 clamp the door body 100. Specifically, the bearing plate 211 rises to a position where its top surface is higher than the conveying device 10, and the push rod 23 lifts the door body 100 from the conveying device 10, and then the push rod 23 descends, so that the door body 100 falls on the bearing plate 211. After the door body 100 falls on the bearing plate 211, the multiple clamping blocks 212 clamp the four sides of the door body 100, so that the door body 100 maintains a preset shape. When the door body 100 is maintained in a preset shape, fasteners are used to connect the frame 120 and the corner bracket 130, so that the multiple frames 120 are fixedly connected as a whole, and the insulating glass 110 is fixed in the area surrounded by the frame 120. After the frame 120 is connected as a whole, glue can be applied at the joint to prevent the frame 120 from flashing. After that, the clamping block 212 is released, the carrying plate 211 descends, and the door body 100 falls on the conveying device 10 and is further conveyed by the conveying device 10. The top rod 23 in the second centering assembly device is not necessary and can be omitted. In step S6, the top rod 23 can also be always in the second position.

[0073] S7, the door body 100 moves to the lifting device 40, which lifts the door body 100 from the conveying device 10, and then wraps a flexible belt around the door body 100. The flexible belt can tighten the door body 100 to prevent the door body 100 from deforming during the subsequent glue curing process. When the lifting device 40 lifts the door body 100, the lifting plate 411 rises, the door body is lifted by the bearing block 412, and after being wrapped with the flexible belt, the lifting plate 411 descends, and the door body continues to be transported by the conveying device 10.

[0074] After passing through the second centering assembly device 220, the door body 100 is set with its back side facing upward, but when the door body 100 is placed later, it is usually set with its front side facing upward. Therefore, the flipping device 30 also includes a second flipping device 320. The second flipping device 320 is arranged between the second centering assembly device 220 and the lifting device 40 in the conveying direction of the conveying device 10. The above-mentioned production method also includes the steps between S6 and S7: S61, using the second flipping device 320 to drive the door body 100 to flip 180° so that the first connecting hole 121 faces downward, and the door body 100 is set with its front side facing upward.

[0075] S8. After the door body 100 moves to the third centering assembly device 230, the door body 100 is placed on the supporting plate 211 of the third centering assembly device 230, and a plurality of clamping blocks 212 on the supporting plate 211 clamp the door body 100 to position the door body 100. Then, the clamping blocks 212 are released, and the transport device 62 transports the door body 100 from the third centering assembly device 230 to the storage rack 61. Specifically, after the door body 100 moves to the third centering assembly device 230, the carrying plate 211 rises to a position where its top surface is higher than the conveying device 10, and the push rod 23 lifts the door body 100 from the conveying device 10, and then the push rod 23 descends to make the door body 100 fall on the carrying plate 211. After the door body 100 falls on the carrying plate 211, the plurality of clamping blocks 212 clamp the four sides of the door body 100 so that the door body 100 can be located at a preset position, and then the transport device 62 transports the door body 100 from the third centering assembly device 230 to the storage rack 61. The push rod 23 in the third centering assembly device is not necessary and may not be provided. In step S8, the push rod 23 may also be always in the second position.

The in-place sensor 64 is connected to the control unit of the assembly line 200. The conveying device 10 can be controlled by the control unit to whether to convey. After the in-place sensor 64 senses that the hollow glass 110 or the door body 100 has arrived at the corresponding device, the conveying line 112 stops. After the operator completes the corresponding operation, the conveying device 10 continues to convey.

[0077] In the above step S8, “the transport device 62 transports the door body 100 from the third centering assembly device 230 to the storage rack 61” specifically includes the following steps:

[0078] The transport device 62 picks up a door body 100 and moves the door body 100 to a position where a certain sensor 64 can sense the door body 100 . The sensor 64 is a first sensor 64 .

[0079] The first sensor 64 senses the position of the door body 100 and sends the obtained information to the control unit;

[0080] The transport device 62 adjusts the position of the door body 100 according to the position information of the door body 100 acquired by the first sensor 64 , and correctly places the door body 100 in the storage layer 611 corresponding to the first sensor 64 .

[0081] In the above steps, the sensor 64 may be a distance sensor, which can measure the distance between the door body 100 and itself to determine the position of the door body 100. The sensor 64 may be provided on multiple sides of the storage rack 61 to sense the position of the door body 100. The transport device 62 adjusts the position of the door body 100 in real time according to the position information of the door body 100, and can place the door body 100 in the correct position in the storage layer 611. The door body 100 is left in the storage layer 611 for a preset period of time (e.g., 12h-24h). After the glue is completely cured, the flexible belt wrapped around the door body 100 can be removed, and then the seal and LED light can be installed on the door body 100.

[0082] The storage layer 611 is provided with multiple layers, and the transport device 62 can place multiple door bodies 100 in the multiple storage layers 611 respectively. When placing multiple door bodies 100, the transport device 62 places the multiple door bodies 100 one by one from the lowest storage layer 611 upwards, so that the door bodies 100 can be pressed on the bottom of the storage rack 61 first to stabilize the center of gravity of the storage rack 61, and when the door bodies 100 are placed from bottom to top, when the transport device 62 is placed, the door bodies 100 placed first will not interfere with the transport device 62.
