Figures 1 to 6 As shown, the automatic grate rack foot pad installation mechanism comprises a loading station 101, a glue injection station 102, an assembly station 103, a pallet assembly 20 for supporting the grate, and a conveying assembly 30 (not shown in the figure) for conveying the pallet to each station; the pallet assembly 20 comprises a pallet 21, and a flip shaft 211 and a connecting shaft 212 are respectively provided on both sides of the pallet 21, the connecting shaft 212 is connected to the conveying assembly 30, the flip shaft 211 is connected to a flip driver for driving the pallet to flip, and a through-hole 2101 is provided on the pallet 21 for the grate legs to pass through; a first glue injection assembly 40 for injecting glue into the grate legs flipped to the back of the pallet facing upward is provided above the glue injection station 102, a turntable 50 for conveying foot pads is provided below the assembly station 103, and a turntable 50 is provided below the turntable 50 A lifting assembly 60 is provided for lifting and installing the foot pad 200 in the turntable to the furnace leg 1001 on the pallet. The pallet 21 carrying the furnace rack 100 is transferred from the loading station 101 to the glue injection station 102. The flip driver drives the pallet 41 to flip 180 degrees, and the back of the pallet 21 faces upward. The first glue injection assembly 40 automatically injects glue to the furnace leg on the furnace rack. The pallet 21 continues to be transferred from the glue injection station 102 to the assembly station 103. The flip driver drives the pallet 21 to flip 180 degrees again, and the pallet 21 returns to facing up. The lifting assembly 60 lifts the foot pad 200 on the turntable 50 that is under the furnace leg and presses it to assemble it on the furnace leg 1001. This replaces manual labor, makes the quality of the assembled foot pad stable and reliable, and reduces quality problems such as glue contamination and other manual installation of foot pads.

As a preferred solution, the lifting driver and the positioning driver can use a cylinder.

[0025] A second glue injection assembly 70 for injecting glue into the foot pad inside the turntable is provided on one side of the turntable. Before jacking, the second glue injection assembly 70 is used to inject glue into the foot pad 200 located just below the stove foot, and then the jacking assembly 60 is used to lift the foot pad and press it to assemble it on the stove foot. In this way, before assembly, glue is injected into the stove foot and the foot pad respectively to ensure the stable assembly quality of the foot pad.

When the eccentric shaft 221 rotates, it drives the connecting rod 24 to be inserted into the slot 2104 of the support plate 21 through the connecting sleeve 23, thereby pulling the block 25 in the chute 11 out of the chute 11, so that the block 25 In the gap between the work station plate 10 and one side of the support plate, the flip driver drives the support plate 21 to flip 180 degrees, with the back of the support plate 21 facing upward, and then the rotating motor is started to insert the plug 25 into the chute 11; 3) The first glue injection component 40 is based on the four furnace feet, and the glue injector is connected to four conduits at the same time, injecting glue into the four furnace feet at the same time; 4) The conveying component 30 conveys the support plate 21 carrying the furnace rack from the glue injection station to the assembly station 103, and the rotating motor is started to make the plug 25 exit the chute 11, and the flip driver drives the support plate 21 to flip 180 degrees again, with the front of the support plate 21 facing upward, and then Start the rotary motor to insert the plug 25 into the slide 11; 5) The two second glue injection assemblies 70 inject glue into the four foot pads at the same time; 6) Under the action of the jacking drive, the connecting column 63 rises, driving the four jacking seats 61 to rise, and then until they are just below the foot pads 200, and then continue to rise to a certain distance until the four foot pads 200 are separated from the original foot pad positions on the four turntables 50 and stop at a height that does not interfere with the rotation of the four turntables 50; 7) Under the action of the positioning drive, the sleeve 64 rises, driving the positioning seat 62 and the positioning pin 621 to rise at the same time, and the four positioning pins 6 21 passes through the through hole 611 on the lifting seat 61 and the hole on the foot pad 200; 8) After passing through the lifting seat 61 and the foot pad 200, the sleeve 64 continues to rise. When the four positioning seats 62 and the four lifting seats 61 are fitted together, the lifting driver drives the connecting column 63 to rise together until the four positioning pins 621 reach the bottom of the holes of the four furnace feet 1001 of the furnace frame, and then the sleeve 64 stops rising; at this time, the connecting column 63 continues to rise, and the sleeve 64 is stopped. During the rising process, the connecting column 63 drives the foot pad along the four positioning pins 621 to lift the foot pad 200 to be assembled on the corresponding furnace foot 1001.
