[0016] A method for using an automatic processing device for elevator doors comprises the following steps:

[0017] Step 1, control and open multiple first linear electric rails to drive the buffer longitudinal frame to move horizontally, away from between the two feeding parts, and stack multiple groups of internal support rods in the buffer longitudinal frame for caching, the limit stopper rod limits the internal support rod at the bottom position, and the limit pressure plate squeezes and limits the second to last internal support rod at the bottom, and then, control and open multiple first linear electric rails again to drive the buffer longitudinal frame to drive the multiple groups of internal support rods to move horizontally, and place them between the two feeding parts, so that the bottom end of the buffer longitudinal frame contacts the top end of the side fixed longitudinal plate and the end fixed longitudinal plate;

[0018] When loading is required, the first telescopic cylinder is controlled to drive the limit stop bars on both sides to move backwards, and the internal support rod at the bottom position automatically drops and falls into the uppermost material storage bin. Subsequently, the first telescopic cylinder is controlled again to drive the limit stop bars on both sides to shift and reset. Subsequently, the second telescopic cylinder is controlled to drive the limit pressure plates on both sides to move backwards, and the second-to-last internal support rod at the bottom automatically drops and falls on the limit stop bars. Subsequently, the second telescopic cylinder is controlled again to drive the limit pressure plates on both sides to shift and reset. The limit pressure plates on both sides squeeze and limit the second-to-last internal support rod at the bottom again, so that the lower internal support rod falls into the uppermost material storage bin.

[0019] Step 2: Place the outer door frame on multiple transport rollers, and coordinate with the positioning of multiple positioning side rollers to automatically transport the outer door frame, and transport the outer door frame to the bottom of the two loading parts, so that the position of the internal support rod in the outer door frame corresponds to the position of the material storage bin;

[0020] Step 3: Start the first motor in the feeding parts on both sides through synchronous control, drive the feeding shafts on both sides to rotate synchronously in the opposite direction, thereby control the rotation of multiple feeding sprockets, and then control the multiple feeding chains on both sides to transmit synchronously in the opposite direction, thereby driving the multiple material racks at the inner end positions of the feeding parts on both sides to transmit downward in the opposite direction synchronously, and sequentially transmit the material storage bin at the top position to the bottom position for loading the internal support rod. After the internal support rod moves to the bottom position, it automatically detaches from the material storage bin, and the internal support rod is accurately placed on the inner side of the external door frame through the limiting of the side fixed longitudinal plate and the end fixed longitudinal plate;

[0021] Step 4: Control and open the multiple first telescopic rods to drive the first welding heads to tilt downward, so that the heads of the multiple first welding heads contact the internal support rods and the inner connecting positions of the external door frame, and perform pre-welding and fixing;

[0022] Then continue to transport the external door frame and the internal support rod, and use the first welding head to fully weld other positions of the external door frame and the internal support rod in transportation;

[0023] Step 5. After the first welding head fully welds the external door frame and other positions of the internal support rods during transportation, it continues to be transported to the bottom of the welding device. Then, according to the width of the internal support rods, the fourth telescopic cylinder is controlled to drive the second welding heads on both sides to move back and adjust the spacing. Then, the second telescopic rod is controlled to drive the second welding head to move downward at an angle, so that the heads of the second welding heads on both sides contact other positions connected to the internal support rods and the inner side of the external door frame, and the second linear electric rail is controlled to drive the second welding heads on both sides to move horizontally, so as to automatically and completely weld the internal support rods and the external door frame.

At the same time, the internal struts and the inner connection positions of the external door frame are pre-welded and fixed to improve the stability of the subsequent synchronous transmission of the external door frame and the internal struts.

[0026] 2. By setting up a loading device and using a transportation device in conjunction with it, the external door frame and internal support rods can be positioned and automatically transported, and at the same time, the pre-welded internal support rods and other positions of the external door frame can be automatically fully welded.

Subsequently, the second telescopic cylinder 462 is controlled to drive the limit pressing plates 46 on both sides to shift backwards, and the second-to-last internal support rod at the bottom automatically drops and falls on the limit blocking rod 45. Subsequently, the second telescopic cylinder 462 is controlled again to drive the limit pressing plates 46 on both sides to shift and reset. The limit pressing plates 46 on both sides squeeze and limit the second-to-last internal support rod at the bottom again, so that the lower internal support rod falls into the uppermost material storage bin.

[0059] Step 2: Place the outer door frame on the multiple transport rollers 33, and cooperate with the positioning of the multiple positioning side rollers 351 to automatically transport the outer door frame, and transport the outer door frame to the bottom of the two loading parts 7, so that the position of the inner support rod in the outer door frame corresponds to the position of the material storage bin;

[0060] Step 3: Start the first motor 723 in the feeding parts 7 on both sides through synchronous control, drive the feeding shafts 72 on both sides to rotate synchronously in the opposite direction, thereby control the multiple feeding sprockets 721 to rotate, and then control the multiple feeding chains 722 on both sides to transmit synchronously in the opposite direction, thereby driving the multiple material racks 73 at the inner end positions of the feeding parts 7 on both sides to synchronously reverse and transmit downward, and successively transmit the material bin at the top position to the bottom position for loading the internal support rod. After the internal support rod moves to the bottom position, it automatically detaches from the material bin, and the internal support rod is accurately placed on the inner side of the outer door frame through the limiting of the side fixed longitudinal plate 74 and the end fixed longitudinal plate 75;

[0061] Step 4: Control and open the multiple first telescopic rods 761 to drive the first welding heads 763 to tilt downward, so that the heads of the multiple first welding heads 763 contact the inner support rods and the inner connecting positions of the outer door frame, and perform pre-welding and fixing;

[0062] Then, the outer door frame and the inner support rod are continuously transported, and at the same time, the first welding head 763 is used to fully weld other positions of the outer door frame and the inner support rod being transported;

[0063] Step 5. After the first welding head 763 fully welds the external door frame and other positions of the internal struts during transportation, it continues to be transported to the bottom of the welding device 5. Then, according to the width of the internal struts, the fourth telescopic cylinder 54 is controlled to drive the second welding heads 57 on both sides to move backwards and adjust the spacing. Then, the second telescopic rod 551 is controlled to drive the second welding heads 57 to move downward tilted, so that the heads of the second welding heads 57 on both sides are in contact with other positions connected to the inner side of the internal struts and the external door frame, and the second linear electric rail 52 is controlled to drive the second welding heads 57 on both sides to move horizontally, so as to automatically and completely weld the internal struts and the external door frame.
