Working principle: because the equipment is divided into three different sections, the working principle is divided into three blocks, namely 1, the assembly and detection of the bypass hole and the throttle hole respectively; 2. screwing and detecting a gas valve; 3. setting and performance classification of big and small fires.

In the first step of the assembly section 2, the preliminary part is manually assembled in the prepared preliminary mold, and then placed in the valve seat on the rotary disk 5, the first preliminary mold placed on the valve seat is pointed out, the gas valve is brought under the bypass hole detecting mechanism 6 along with the rotation of the rotary disk 5 by a certain angle (because the bypass hole detecting mechanism 6 is in the inverted L shape, one side of the transverse plate is positioned above the rotary disk 5, and the detecting probe 61 is also arranged above the rotary disk 5, the detecting probe 61 is arranged on the bottom surface of the transverse plate, and the detecting probe 61 is in driving connection with the first translational power source 62 on the upper surface of the transverse plate), as shown in fig. 3 and 8, the two detecting probes 61 on the bypass hole detecting mechanism 6 are 2, and when the gas valve is turned over, the two detecting probes 61 are just aligned with the bypass hole 101 of the gas valve, at this time, the cylinder drives the two detecting probes 61 to be in the bypass hole 101 downwards, if the bypass hole 101 is blocked, the detecting probe 61 is in the bottom surface of the transverse plate, and the distance of the bypass hole 101 is set to be not to be in the acceptable, and whether the distance of the gas valve is in the condition that the end is acceptable or not is set.

In the second step, after the bypass hole 101 is detected, the bypass hole 101 needs to be screwed up and locked, then the rotating disc 5 rotates a certain angle again, the die with the piece on the rotating disc 5 rotates to the lower part of the first screw locking mechanism 7 (since the bypass hole 101 is two in the prior detection, the number of corresponding screwing rods 71 is two, and the screwing rods 71 are screwed on the bypass hole 101, which will be described in detail later), and the two screwing rods 71 are exactly aligned with the two bypass holes 101 of the gas valve, at this time, the screwing rods 71 automatically rotate the screws into the bypass holes 101.

And thirdly, after the bypass hole is screwed and locked, the throttle hole 102 on the die after the first screwing is required to be installed, at this time, the rotating disc 5 rotates by a certain angle again, the die after the first screwing on the rotating disc 5 rotates to the lower part of the throttle hole assembly mechanism 8 (the throttle hole 102 on the gas valve is one), the installation suction head 81 is driven to the upper part of the discharging station 154 on one side of the throttle hole assembly mechanism 8 through a cylinder (the side of the throttle hole assembly mechanism 8 is provided with a feeding component 15, the shaking disc 151 with the throttle pipe continuously shakes the throttle pipe which is placed irregularly into a channel on the shaking disc 151, whether the forward and reverse directions of the throttle pipe in the channel are correct or not is detected through the forward and reverse detector 152, if the forward and reverse directions are not consistent, the throttle pipe is sucked away, the throttle pipe which is correct and qualified is slid to the discharging station 154 in the chute 153 for sucking the suction head 81), the throttle pipe on the discharging station 154 is sucked through the driving of the other cylinder, and then the two cylinders are respectively driven to the throttle pipe on the last throttle hole 102 on the upper part of the die after the first screwing on, and the suction head 81 is pressed down.

Fourth, after the orifice 102 is installed, the air tightness of the orifice 102 needs to be detected, at this time, the rotating disc 5 rotates a certain angle again to rotate the gas valve below the air tightness detecting mechanism 16, the detecting head 161 just aims at the detecting hole on the gas valve, at this time, the detecting head 161 can be driven by the air cylinder to block the orifice 102, then air pressure is filled into the inside through the detecting head 161, and whether the orifice 102 assembled by the orifice has an air leakage phenomenon (the function of the orifice 102 is used for adjusting the air flow of the gas valve, and the orifice 102 is arranged on the basic gas valve), so that the adjustment is the prior art without excessive detailed explanation.

Fifth and sixth steps, when the gas tightness is detected, the rotating disc 5 rotates a certain angle, and the gas valves on the rotating disc 5 rotate to one side of the two-dimensional code printer 17, the printing port of the two-dimensional code printer 17 is aligned to one side of the mold after the pipe is installed, the light of the two-dimensional code printer 17 irradiates on one side of the mold after the pipe is installed, and then the surface of the mold after the pipe is installed is provided with a two-dimensional code to represent that each gas valve has an independent mark; after the two-dimensional code is printed, the mould after the tubing is manually taken down from the valve seat, and other parts on the frame 1 are manually installed in the mould after the tubing.

The first step of the scanning detection section 3 is that, when the assembled mold is placed on the starting end of the first slide rail 91 (the assembled mold is manually assembled after being taken down, and then the assembled mold is changed into the assembled mold), at this time, the two-dimension code scanner 18 arranged on one side of the starting end of the first slide rail 91 automatically scans the two-dimension code on the side surface of the assembled mold, records whether the assembled mold is qualified or not and records the state model of the assembled mold (because the sixth step in the assembly section 2 is that when the assembled mold is manually taken down from the rotating disc 5 to manually assemble other internal parts, a judgment is made as to whether the assembled mold is qualified or not, and whether the records are qualified or not is made in the operation of the previous steps).

In the second step, the die after the two-dimension code is assembled after being scanned is driven by the air cylinder to move to the lower part of the second screw locking mechanism 11 in the first slideway 91, and at this time, the first locking rod 111 on the second screw locking mechanism 11 is aligned with the screw hole on the die after the two-dimension code is assembled to be locked by screwing.

The third step and the fourth step, the second mold after screwing continues to slide in the first slide way 91 until between two visual detectors 10 (the first visual detectors 10 in the invention are respectively arranged on two sides of the first slide way 91 and are symmetrical to each other), the first visual detectors 10 irradiate detection light on the second mold after screwing, and whether gaps exist on the surface after the second mold after screwing is assembled or not is detected, and whether the distance between the uppermost end of the second mold after screwing and the detection light is a composite standard value or not can be detected; and sliding the die after the second screwing to the extreme end of the first slideway after the detection, manually taking down the die after the second screwing and assembling the last upper cover.

Sixthly, after the screws are locked, the mold after the third screwing continues to slide on the second slide way 92, and when the mold slides between the second visual detectors 100 on two sides of the second slide way 921, the second visual detectors 100 irradiate detection light on the mold after the third screwing, and whether gaps exist on the surface of the mold after the gas valve is assembled or not is detected, and whether the distance between the uppermost end of the mold after the third screwing and the detection light is compounded with a standard value or not can be detected; the molded gas valve after detection slides to the extreme end of the second slideway 92, namely to the lower end of the sliding shaft 13 for taking the part of the part clamping hand 14.
