[0015] An assembly method for a curtain wall clamping rapid positioning assembly device, comprising the following steps:

[0016] S1. The fixing device is placed at the desired position, and the bolts on the fixing device are rotated so that the bolts extend to the desired fixing position;

[0017] S2. When the bolt and the fixing device are approaching, the connecting frame on the bolt and the fixing device gradually approach each other, and then squeeze the spring. The spring itself is elastic, so the spring squeezes the bolt. After the bolt is squeezed, the thread on the bolt fits more closely with the inner wall of the fixing device, increasing the friction between the bolt thread and the inner wall thread of the fixing device, and reducing the loosening of the bolt;

[0018] S3, the first magnetic block and the second magnetic block are magnetically repelling each other. After the first magnetic block and the second magnetic block are close to each other, the magnetic repulsion between the first magnetic block and the second magnetic block squeezes the bolt, further increasing the friction between the thread of the fixing device and the thread of the bolt, so that the bolt is more firmly fixed;

[0019] S4. Place the four corners of the curtain wall into the four limit blocks respectively. When the curtain wall extends into the limit blocks, the curtain wall squeezes the horizontal plate. The arc rod and the movable rod are located at the two ends of the first torsion spring respectively. When one end is squeezed, the other end will move accordingly. When the arc rod is squeezed, the movable rod will move toward the curtain wall, thereby making the rubber block fit with the curtain wall and fix the rubber block to the curtain wall, thereby increasing the stability of the curtain wall and reducing the shaking of the curtain wall.

[0020] S5. When the curtain wall is placed in the limit block, the curtain wall squeezes the pressure plate, and then the pressure plate follows the decline. The connection between the elastic band and the connecting block, during the decline of the elastic band, the connecting block follows the decline. During the decline of the connecting block, the connecting block squeezes the gas inside the airflow bin, and then the space between the airflow bin and the top of the connecting block increases. The connecting block and the airflow bin are in a sealed state, and the space between the top of the connecting block and the airflow bin increases. The amount of air remains unchanged, which reduces the density of the air, so it is sucked through the holes;

[0021] S6. During the suction process, the card block is pulled, and then the curtain wall is fixed by the suction cup. The suction cup is attached to the curtain wall, and the curtain wall is further stabilized under the suction of the airflow. The connecting block squeezes the air at the bottom of the airflow bin, and then the air is blown out from the air outlet to clean the dirt on the corner of the curtain wall and the inner wall of the limit block, so that the curtain wall can fit in the limit block.

[0022] The present invention provides a curtain wall clamping rapid positioning assembly device and assembly method, which has the following beneficial effects:

[0023] 1. The curtain wall clamping quick positioning assembly device and assembly method are located at the four corners of the curtain wall through the limit blocks to fix the four corners, thereby ensuring the limitation of the curtain wall, and the length of the connecting rod is fixed, so that the curtain wall will not retreat, thereby ensuring the stability of the curtain wall.

[0024] 2. The curtain wall clamping quick positioning assembly device and assembly method are provided with a spring between the bolt and the fixing device. Under the elastic lifting of the spring, the bolt and the fixing device threads are more closely fitted, and the friction between the threads is increased after fitting, thereby ensuring the fixation between the fixing device and the bolt and reducing the activity of the bolt. The magnetic repulsion between the first magnetic block and the second magnetic block and the lifting of the bolt further increase the fixation between the threads and further reduce the activity of the bolt.

[0025] 3. The curtain wall clamping quick positioning assembly device and assembly method utilize the weight of the curtain wall through the compression of the curtain wall on the transverse plate, drive the movement of the device to fix the curtain wall, and the gravity of the curtain wall reduces the setting of additional electronic devices. The gravity of the curtain wall squeezes the arc rod to make the rubber block fit with the curtain wall, further reducing the movement of the curtain wall and reducing the shaking of the curtain wall. The curtain wall squeezes the pressure plate to make the suction cup produce a suction effect, and the suction of the suction cup on the curtain wall fixes the curtain wall. The fixation of the suction cup reduces the shaking of the curtain wall and ensures the protection of the curtain wall. BRIEF DESCRIPTION OF THE DRAWINGS

A suction cup 38 is fixedly connected to the outer wall of the limit block 14 at the position of the hole 310, and an airflow port 39 is provided on the outer wall of the suction cup 38.

[0045] An assembly method for a curtain wall clamping rapid positioning assembly device, comprising the following steps:

[0046] S1, the fixing device 11 is placed at a desired position, and the bolt 21 on the fixing device 11 is rotated so that the bolt 21 extends into the desired fixing position;

[0047] S2. When the bolt 21 and the fixing device 11 are approaching each other, the connecting frame 24 on the bolt 21 and the fixing device 11 gradually approach each other, and then the spring 25 is squeezed. The spring 25 itself is elastic, so the spring 25 squeezes the bolt 21. After the bolt 21 is squeezed, the thread on the bolt 21 fits more closely with the inner wall of the fixing device 11, which increases the friction between the thread of the bolt 21 and the thread of the inner wall of the fixing device 11, and reduces the loosening of the bolt 21.

[0048] S3, the first magnetic block 23 and the second magnetic block 26 are magnetically repelling. After the first magnetic block 23 and the second magnetic block 26 are close to each other, the magnetic repulsion between the first magnetic block 23 and the second magnetic block 26 squeezes the bolt 21, further increasing the friction between the thread of the fixing device 11 and the thread of the bolt 21, so that the bolt 21 is more firmly fixed;

[0049] S4, placing the four corners of the curtain wall into the four limit blocks 14 respectively. When the curtain wall extends into the limit blocks 14, the curtain wall squeezes the horizontal plate 34. The arc rod 33 and the movable rod 32 are respectively located at the two ends of the first torsion spring 35. When one end is squeezed, the other end will move accordingly. When the arc rod 33 is squeezed, the movable rod 32 will move toward the curtain wall, thereby making the rubber block 31 fit with the curtain wall, so that the rubber block 31 fixes the curtain wall, thereby increasing the stability of the curtain wall and reducing the shaking of the curtain wall.

[0050] S5. When the curtain wall is placed in the limit block 14, the curtain wall squeezes the pressure plate 36, and then the pressure plate 36 follows the decline, and the elastic band 312 is connected to the connecting block 311. During the decline of the elastic band 312, the connecting block 311 follows the decline. During the decline of the connecting block 311, the connecting block 311 squeezes the gas inside the airflow bin 313, and then the space between the airflow bin 313 and the top of the connecting block 311 is increased. The connecting block 311 and the airflow bin 313 are in a sealed state, and the space between the top of the connecting block 311 and the airflow bin 313 is increased. The amount of air remains unchanged, which reduces the density of the air, so it is sucked through the hole 310;

[0051] S6. During the suction process, the clamping block 315 is pulled, and then the curtain wall is fixed by the suction cup 38. The suction cup 38 is attached to the curtain wall, and the curtain wall is further stabilized under the suction of the airflow. The connecting block 311 squeezes the air at the bottom of the airflow bin 313, and then the air is blown out from the blowing port 37 to clean the dirt on the corner of the curtain wall and the inner wall of the limit block 14, so that the curtain wall can fit in the limit block 14.

[0052] When in use, the fixing device 11 is placed at the desired position, and the bolt 21 on the fixing device 11 is rotated to extend the bolt 21 into the desired fixed position. When the bolt 21 and the fixing device 11 are approaching each other, the connecting frame 24 on the bolt 21 and the fixing device 11 are gradually approached, and then the spring 25 is squeezed. The spring 25 itself has elasticity, so the spring 25 will squeeze the bolt 21. After the bolt 21 is squeezed, the thread on the bolt 21 is more closely fitted to the inner wall of the fixing device 11, which increases the friction between the thread of the bolt 21 and the thread of the inner wall of the fixing device 11, and reduces the loosening of the bolt 21. The first magnetic block 23 and the second magnetic block 26 are magnetically repelled. After the first magnetic block 23 and the second magnetic block 26 are close to each other, the magnetic repulsion of the first magnetic block 23 and the second magnetic block 26 further squeezes the bolt 21, further increasing the friction between the thread of the fixing device 11 and the thread of the bolt 21, so that the bolt 21 is more firmly fixed. The four corners of the curtain wall are respectively placed in the four limit blocks 14. When the curtain wall extends into the limit blocks 14, the curtain wall squeezes the cross plate 34. The arc rod 33 and the movable rod 32 are respectively located at the two ends of the first torsion spring 35. When one end is squeezed, the other end will follow the movement. When the arc rod 33 is squeezed, the movable rod 32 The rod 32 will approach the direction of the curtain wall, so that the rubber block 31 fits with the curtain wall, and the rubber block 31 fixes the curtain wall, thereby increasing the stability of the curtain wall and reducing the shaking of the curtain wall. Moreover, when the curtain wall is placed in the limiting block 14, the curtain wall squeezes the pressure plate 36, and then the pressure plate 36 follows the decline, and the elastic band 312 is connected to the connecting block 311. During the descent of the elastic band 312, the connecting block 311 follows the decline. During the descent of the connecting block 311, the connecting block 311 squeezes the gas inside the airflow bin 313, and then the space between the airflow bin 313 and the top of the connecting block 311 is increased, and the connecting block 311 is connected to the connecting block 312. 11 and the airflow bin 313 are in a sealed state, the space between the top of the connecting block 311 and the airflow bin 313 is increased, the amount of air remains unchanged, and the density of the air is reduced, so suction is drawn through the hole 310. During the suction process, the clamping block 315 is pulled, and then the curtain wall is fixed by the suction cup 38. The suction cup 38 is attached to the curtain wall, and the curtain wall is further stabilized under the suction of the airflow. The connecting block 311 squeezes the air at the bottom of the airflow bin 313, and then the air is blown out from the blowing port 37 to clean the dirt on the corner of the curtain wall and the inner wall of the limit block 14, so that the curtain wall can fit in the limit block 14.
