The outer wall of the sliding seats is movably connected to the slider two, and suction heads are fixedly connected to the bottom of both sliding seats.

[0015] A method for assembling a fire door includes the following steps:

[0016] S1. When it is necessary to assemble the fire door, first place the first door panel on the second placement platform, and then the second door panel and the flame retardant material are transported from the feeding device to both sides of the equipment.

[0017] S2. The first door panel placed on the second placement platform will be moved to the first placement platform by the conveyor belt. Then, push rod two will be activated to lift the extension plate and push rod one will be activated to move the first door panel to the top of the mounting platform. At this time, push rod two will reset the extension plate and push rod one will push the long plate back to its original position.

[0018] S3. After the first door panel is placed on the mounting platform, the push rod four is activated to lift the fire door a certain distance through the ball bearings, and the push rod three is activated to drive the blocking plate and positioning plate to center the first door panel, which facilitates the subsequent installation of flame-retardant materials and the second door panel.

[0019] S4. After the first door panel is positioned, the installation mechanism first places the flame-retardant material inside the first door panel. While placing the flame-retardant material, it will also lift the second door panel. After the flame-retardant material is installed, the second door panel is moved to the top of the installation platform, and the first door panel and the second door panel are merged to complete the installation. Then, it is moved to another placement platform by the moving component and then leaves the equipment by the conveyor belt.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] 1. By setting up an installation mechanism, this invention can quickly install the flame-retardant material of the fire door and the door panel on the other side together, avoiding the need for workers to handle the parts multiple times, automatically completing the installation of the fire door, improving the efficiency of fire door production, and reducing labor costs.

[0022] 2. By incorporating a movable component, this invention can automatically push the fire door off the device and install the next uninstalled fire door onto the mounting platform after the previous fire door has been installed, thereby improving the installation efficiency of the device.

[0023] 3. By setting a positioning component, the present invention performs a centering test on the fire door before the equipment is ready to install the fireproof board. This avoids the fire door not being centered during transportation, which would cause subsequent accessories to be unable to align with the fire door and thus prevent the accessories from being installed properly, thereby improving the stability of equipment installation.

[0024] 4. By setting up auxiliary components, the fire door is lifted by the bottom ball bearings before it is centered and fixed, which avoids friction between the mounting platform and the fire door when the fire door is moved, thus preventing damage to the surface of the fire door and improving the pass rate of fire door production.
