[0066] Figure 2 The invention provides an automatic timing device for pressing hot melt adhesive into a skylight air outlet, comprising:

[0067] The main body 1 is connected by ultra-light aluminum alloy pipes and is assembled by a cylinder 1-1 and a pulley block 1-2.

[0068] The main operation control system 2 is composed of a pneumatic control device 2-1, a cylinder motion control device 2-2, and a mechanism control device 2-3, and is used to enable three groups of sandbags to gradually complete the pressing operation according to the operation sequence.

[0069] like Figure 3 As shown, the model of the first cylinder 1-1-1 of the sunroof outlet hot melt adhesive pressing automatic timing device is: CD912N50-1000Z, the model of the second cylinder 1-1-2 is: C91ZN50-800Z, and the model of the third cylinder 1-1-3 is: MGPM32-1002. The model of the first switch 2-1-1 is: MOV-O3A, the model of the second switch 2-1-2 is: VM130, and the model of the third switch 2-1-3 and the fourth switch 2-1-4 is: VM131.

[0070] When in use, place the skylight ceiling on the fixture, and glue the designated position of the ceiling; install the air outlet to the designated position, instruct the first switch 2-1-1 to start the first cylinder 1-1-1, and the first sandbag 2-2-1 and the second sandbag 2-2-2 are pressed into the air outlet from top to bottom. The process is as follows: after the first switch 2-1-1 is pressed to open, the first cylinder 1-1-1 starts to move, the cylinder rod withdraws, and is lowered 3 times by the mechanism to the pressing points of the first sandbag 2-2-1 and the second sandbag 2-2-2.

[0071] Glue the left side parts of the air outlet for assembly, command the second switch 2-1-2 to start the second cylinder 1-1-2, and the third sandbag 2-2-3 and the fourth sandbag 2-2-4 are pressed into the air outlet after they reach the designated position from top to bottom. The process is as follows: command the second switch 2-1-2 to start the second cylinder 1-1-2, and the third sandbag 2-2-3 and the fourth sandbag 2-2-4 are pressed into the air outlet after they reach the designated position from top to bottom; after the second switch 2-1-2 is pressed to open, the second cylinder 1-1-2 starts to move, the cylinder rod withdraws, and the mechanism is lowered three times to the pressing points of the third sandbag 2-2-3 and the fourth sandbag 2-2-4.

[0072] Glue the side parts of the right air outlet for assembly, command the third switch 2-1-3 to start the third cylinder 1-1-3, and the fifth sandbag 2-2-5 and the sixth sandbag 2-2-6 are pressed into the air outlet after reaching the designated positions from top to bottom. The process is as follows: command the third switch 2-1-3 to start the third cylinder 1-1-3, and the fifth sandbag 2-2-5 and the sixth sandbag 2-2-6 are pressed into the air outlet after reaching the designated positions from top to bottom; after the third switch 2-1-3 is pressed to open, the third cylinder 1-1-3 starts to move, the cylinder rod withdraws, and the mechanism is lowered three times to the pressing points of the fifth sandbag 2-2-5 and the sixth sandbag 2-2-6.

[0073] When all the sandbags are pressed to the designated position, the operator triggers the mechanism control device 2-3, and the mechanism control device 2-3 starts timing. After 20 seconds, all the pressed sandbags return to their positions at the same time. After all the operations are completed, the operator confirms the position of the sandbags and presses the fourth switch 2-1-4 to start the 20-second delay mechanism. After 20 seconds, the first sandbag 2-2-1, the second sandbag 2-2-2, the third sandbag 2-2-3, the fourth sandbag 2-2-4, the fifth sandbag 2-2-5, and the sixth sandbag 2-2-6 are all automatically lifted and return to the origin to complete the action.

[0076] like Figure 5As shown, the air circuit principle of the automatic timing device for pressing hot melt glue into the skylight air outlet is as follows: after gluing, place the middle air outlet and press the first switch 2-1-1. At this time, the third sandbag 2-2-3 and the fourth sandbag 2-2-4 begin to descend under the action of the second cylinder 1-1-2, pressing the middle air outlet; after gluing, place the left air outlet and the right air outlet, and press the second switch 2-1-2 and the third switch 2-1-3 respectively. The first sandbag 2-2-1 and the second sandbag 2-2-2 begin to descend under the action of the first cylinder 1-1-1, and the fifth sandbag 2-2-5 and the sixth sandbag 2-2-6 begin to descend under the action of the third cylinder 1-1-3, pressing the air outlets on both sides; press the fourth switch 2-1-4, and start timing for 20 seconds. Then all the sandbags are simultaneously pulled up to the initial state by the first cylinder 1-1-1, the second cylinder 1-1-2, and the third cylinder 1-1-3, and the operation is completed. The 1-1 lifting mechanism of the cylinder body is used to hang the sandbag above the pressing reference point, thereby ensuring the accuracy of the pressing reference point. Ensure the quality. A pneumatic control button is installed, and the sandbag can be pressed down by pressing the button, eliminating the manual extraction of the sandbag. Reduced labor intensity. A delay program of the air circuit mechanism is made. After the sandbag is pressed down, the air outlet is pressed for 20 seconds and then automatically lifted. Eliminate the operation waiting for the stopwatch timing and the operation delay. Through pure pneumatic control switches and speed regulating valves, low cost and time timing effects can be achieved. Lightweight and no electricity are used, which is safer. The control process does not use PLC and has low cost.

[0077] The technical solution of the present invention is further described below in conjunction with the working principle.

[0079] The hardware involved in the present invention includes: 4 balancers 1-3Kg EW-3;

[0080] Green pneumatic switch 2 MOV-O3A;

[0081] Yellow pneumatic switch 6 VM130;

[0082] Pneumatic switch 4 VM131;

[0083] 7 2-position 5-way valves 4A120-06;

[0084] 1 red gas valve VHS30-02A-X1;

[0085] 1 red gas valve VHS30-02B-X1;

[0086] Barometer 2 AFR2000;

[0087] 1000 cylinders 5 pcs CD912N50-1000Z;

[0094] The operator places the skylight ceiling on a specific jig and glues the designated position of the ceiling. That is, the overall jig placement diagram is prepared for the working state (the original position of the mechanism).

[0095] Install the air outlet to the designated position, instruct the first switch to start a group of cylinders, and the sandbags are pressed into the air outlet schematic diagram after reaching the designated position from top to bottom.

[0096] The first switch is pressed to open, the second cylinder starts to move, the cylinder rod withdraws, and the mechanism is lowered 3 times to the sandbag pressing point.

[0097] Glue the parts on the left side of the air outlet for assembly, command the second switch and the second cylinder to start, and press the sandbag into the air outlet from top to bottom after reaching the designated position. The principle is as follows:

[0098] The second switch is pressed to start the first cylinder, and the first cylinder pushes out to start the first sandbag and the second sandbag to the pressing position;

[0099] The third switch is pressed to start the third cylinder, and the third cylinder pushes out to start the fifth sandbag and the sixth sandbag to the pressing position.

[0100] The present invention provides a principle that when all the sandbags are pressed to a specified position, an operator touches a switch, and a device starts timing for 20 seconds, and then all the pressed sandbags return to their positions simultaneously.

[0101] After all the operations are completed, the operator confirms the position of the sandbags, presses the fourth switch to start, and activates the 20-second delay mechanism.

The first and second sandbags begin to drop under the action of the first cylinder, and the fifth and sixth sandbags begin to drop under the action of the third cylinder, pressing the air outlets on both sides;

[0105] Step 3: Press the fourth switch, and the 20-second countdown will begin. Then all the sandbags will be pulled up to their initial state by the first, second, and third cylinders at the same time, and the operation is completed.

[0106] The technical effects of the present invention are further described below in conjunction with simulation experiments.
