[0037] In this embodiment: the bridge housing high-efficiency welding production line is mainly divided into three parts: welding mechanism 1, unloading mechanism 2 and loading mechanism 3. When the production line is working, the loading swing arm 303 is first driven to rotate by the loading motor 302, thereby further driving the swing plate 305 to swing back and forth relative to the mounting seat 301. When the adsorption plate 310 moves to a vertical position, the pump 2 311 is started again, and the bridge housing 102 is fixed to the bottom of the adsorption plate 310 under the action of multiple groups of suction cups 2 312. When the adsorption plate 310 swings 90 degrees and moves to a horizontal position, the pump 2 311 is turned off again, and the bridge housing 102 is placed on the conveying roller 101. When the bridge housing 102 is conveyed to the bottom of the unloading mechanism 2 by the conveying roller 101, the unloading motor 215 is started. When the engagement arm 223 enters the first vertical portion 212 from the second vertical portion 213, the inner push rod 227 and the outer push rod 228 on both sides will press the seesaw 208 upward, and the hook plate 207 will be separated from the bottom reinforcement ring 104, and the clamping plates 210 on both sides will deflect inward and clamp all reinforcement rings 104 except the bottom reinforcement ring 104, and the bottom reinforcement ring 104 will be fixed to the suction cup 1 226. When moving from top to bottom, the engagement arm 223 enters the horizontal portion 214 and the second vertical portion 213 from the first vertical portion 212 in turn, and the turning frame 224 realizes a 180-degree turn and then places the reinforcement ring 104 on the bridge housing 102. After the bridge housing 102 and the reinforcement ring 104 are transported to the bottom of the welding mechanism 1, the welding gun 118 and the rotating motor 115 are started to perform 360-degree all-round welding processing on the connection.

[0038] See attached Figure 1 -Attached Figure 3 The two sides of the bridge housing 102 include symmetrical bridge arms 103, and the bottom of the placement bin 313 is provided with a limit groove 316 that cooperates with the bridge arm 103. A plurality of sets of return springs 314 are arranged on the inner wall of the placement bin 313, and the inner side of the return spring 314 is connected with an extrusion plate 315; a feeding motor 302 is also installed on the mounting seat 301, and the output end of the feeding motor 302 is connected to a feeding swing arm 303, and the end of the feeding swing arm 303 is connected to a linkage plate 304; a swing plate 305 is also movably arranged on the mounting seat 301, and the swing plate 305 is located between the rotating seat 306 and the feeding motor 302, and the other end of the linkage plate 304 is movably connected to the middle part of the swing plate 305; the bottom of the sliding arm 308 is movably connected to the top of the swing plate 305.

[0039] In this embodiment, in order to automatically push multiple groups of bridge housings 102 to a position close to the adsorption plate 310, a pressing plate 315 is designed, and under the action of the limit groove 316, the bridge housing 102 is more stable when sliding. When the feeding swing arm 303 drives the linkage plate 304 to move, the swing plate 305 can swing back and forth relative to the mounting seat 301, and the swing amplitude is 90 degrees, thereby driving the adsorption plate 310 to switch back and forth between the vertical and horizontal states.

[0040] See attached Figure 2 -Attached Figure 3 A sliding cavity 307 cooperating with the sliding arm 308 is provided inside the rotating seat 306; a pump 311 is installed on the back of the adsorption plate 310, and a plurality of suction cups 312 are provided at the bottom of the adsorption plate 310.

[0041] In this embodiment: when the adsorption plate 310 moves to a vertical position, the adsorption plate 310 is located on the side of the placement bin 313. Then the pump 2 311 is started, and the bridge housing 102 is fixed to the bottom of the adsorption plate 310 under the action of the multiple groups of suction cups 2 312. When the adsorption plate 310 swings 90 degrees and moves to a horizontal position, the adsorption plate 310 and the conveying roller 101 remain parallel. Then the pump 2 311 is closed, and the bridge housing 102 is placed on the conveying roller 101.

[0042] See attached Figure 5 and attached Figure 7 The unloading claw 206 includes an inner hook plate 207, and swing holes 205 cooperating with the unloading claw 206 are opened on the inner walls of the swing cavity 204 on both sides; a clamping plate 210 inclined toward the inside is arranged on the top of the hook plate 207, and a seesaw 208 is fixedly arranged on the outer side of the hook plate 207, and multiple groups of return springs 209 are connected to the inner side of the seesaw 208, and the unloading claw 206 is connected to the outer wall of the clamping seat 202 through the return spring 209.

[0043] In this embodiment, when the inner push rod 227 and the outer push rod 228 are separated from the seesaw 208, the unloading claw 206 returns to its original state under the action of the multiple sets of return springs 209. At this time, the hook plate 207 deflects inward, and the clamping plates 210 on both sides deflect outward and separate from all the reinforcing rings 104. At this time, the upper reinforcing ring 104 falls under the action of gravity, and the hook plates 207 on both sides just lock and limit the bottom of the reinforcing ring 104.

[0046] See attached Figure 6 -Attached Figure 7 The steering groove 211 includes a first vertical portion 212 and a second vertical portion 213 on the upper and lower sides, and a horizontal portion 214 is arranged at the connection between the first vertical portion 212 and the second vertical portion 213; a bearing 221 cooperating with the rotating shaft 222 is also installed inside the rotating chamber 220; a plurality of groups of suction cups 226 are installed at the bottom diagonal of the flip frame 224, and a pump 225 is installed on the top of the flip frame 224; an inner push rod 227 cooperating with the seesaw 208 is fixedly arranged on the outer side of the engaging arm 223, and an outer push rod 228 cooperating with the seesaw 208 is fixedly arranged on the outer side of the flip frame 224.

[0047] In this embodiment, the turning groove 211 is a horizontal V-shaped structure. When moving from the bottom to the top, after the engagement arm 223 enters the horizontal part 214 from the second vertical part 213, the flip frame 224 will flip 90 degrees. After the engagement arm 223 enters the first vertical part 212 from the horizontal part 214, the flip frame 224 will flip 90 degrees again. At this time, the inner push rod 227 and the outer push rod 228 on both sides will press the seesaw 208 upwards, and the hook plate 207 will be separated from the bottom reinforcement ring 104. The clamping plates 210 on both sides will deflect inwards and clamp all reinforcement rings 104 except the bottom reinforcement ring 104, and the bottom reinforcement ring 104 will be fixed to the suction cup 1 226.

When the adsorption plate 310 moves to a vertical position, the pump 2 311 is started, and the bridge housing 102 is fixed to the bottom of the adsorption plate 310 under the action of multiple sets of suction cups 2 312. When the adsorption plate 310 swings 90 degrees and moves to a horizontal position, the pump 2 311 is turned off, and the bridge housing 102 is placed on the conveying roller 101. When the bridge housing 102 is conveyed to the bottom of the unloading mechanism 2 by the conveying roller 101, the unloading motor 215 is started.
