[0039] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0040] In this invention, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integrally formed connection; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0041] Reference Figures 1 to 21 This invention discloses a bridge assembly production line, comprising a frame 100, a conveying device, a welding device, and a ring-fitting device. The conveying device is located on the frame 100 and is used to output a bridge cover 920, an O-ring 930, and a bridge body 910 facing downwards. The welding device is located on the frame 100 and is used to pick up and receive the bridge body 910 output by the conveying device, and to transfer and weld the bridge cover 920 output by the conveying device to the bottom side of the received bridge body 910. The ring-fitting device is located on the frame 100 and is used to flip, pick up, and receive the bridge body 910 with the bridge cover 920 welded on it from the welding device. The flipped and picked-up bridge body 910 faces upwards, and the ring-fitting device is used to transfer and fit the O-ring 930 output by the conveying device onto the first plug 911 of the bridge body 910.

[0042] It is understandable that the bridge body 910 facing downwards means that the first plug 911 and the second plug 912 are facing downwards.

[0043] With the above structure, the material conveying device, welding device and ring mounting device provided on the frame 100 cooperate with each other to enable the bridge cover 920 and O-ring 930 to be mounted on the bridge body 910. The above assembly work is done without manual intervention, thus reducing labor costs and thereby reducing the production cost of the connecting bridge.

[0044] The material conveying device includes a conveyor bridge body mechanism 210, a conveyor bridge cover mechanism 220, and an O-ring conveying mechanism 230.

[0045] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 as well as Figure 11 The bridge body conveying mechanism 210 is located on the frame 100 and is used to output the bridge body 910 facing downward. The bridge cover conveying mechanism 220 is located on the frame 100 and is used to output the bridge cover 920. The O-ring conveying mechanism 230 is located on the frame 100 and is used to output the O-ring 930.

[0046] The conveyor bridge mechanism 210 includes a first storage plate frame group 211, a second storage plate frame group 212, a plate shifting assembly 213, and a conveyor bridge frame group 214.

[0047] Reference Figure 1 and Figure 2 The first storage rack assembly 211, the second storage rack assembly 212, the pallet shifting assembly 213, and the conveyor bridge assembly 214 are all mounted on the frame 100. The pallet shifting assembly 213 is provided with a support plate 213A, which is used to receive and support the pallets. The pallet shifting assembly 213 can drive the support plate 213A to move sequentially to the sixteenth position s16, the seventeenth position s17, and the eighteenth position s18. The first storage rack assembly 211 is used to store at least two stacked pallets equipped with bridge bodies 910 (facing downwards), and is used to move the pallets located at... The lowest single receiving plate is transferred to the support plate 213A located at the sixteenth position s16. The bridge conveyor assembly 214 is provided with a bridge conveyor channel for the downward-facing bridge body 910 to pass through. The bridge conveyor channel has a nineteenth position s19 and a twentieth position s20. The bridge conveyor assembly 214 is used to transfer the bridge body 910 on the receiving plate located at the seventeenth position s17 to the twentieth position s20, and to drive the bridge body 910 on the twentieth position s20 to the nineteenth position s19, so as to output the bridge body 910. The second storage plate assembly 212 is used to receive the empty receiving plate on the support plate 213A located at the eighteenth position s18.

[0048] Understandably, when the second storage rack group 212 receives an empty storage plate, the plate transfer assembly 213 can drive the support plate 213A back to the sixteenth position s16, and drive it to move sequentially to the seventeenth position s17 and the eighteenth position s18.

[0049] The plate shifting assembly 213 includes the aforementioned support plate 213A and a first conveyor belt assembly. The first conveyor belt assembly includes two first rollers 213B, a first conveyor belt 213C, and a first drive member 213D. (Refer to...) Figure 2 A support plate 213A is slidably mounted on the frame 100. A first rotating wheel 213B is rotatably connected to the frame 100. A first conveyor belt 213C is fitted onto two first rotating wheels 213B and connected to the support plate 213A. A first driving member 213D is mounted on the frame 100 and connected to one of the first rotating wheels 213B. The first driving member 213D can drive the first conveyor belt 213C to rotate through one of the first rotating wheels 213B, causing the support plate 213A to move sequentially to position 16, position 17, and position 18. The first driving member 213D is a motor.

[0050] The first storage rack assembly 211 includes a first storage rack 211A, a first lifting rack 211B, a second drive unit 211C, and four third drive units 211D. (Refer to...) Figure 2 A first storage plate rack 211A is mounted on the frame 100, and the first storage plate rack 211A has a first storage plate cavity 211A1. A first lifting frame 211B is slidably mounted on the frame 100, and the first lifting frame 211B is located below the first storage plate cavity 211A1. A second driving member 211C is mounted on the frame 100, and the output end of the second driving member 211C is connected to the first lifting frame 211B. The second driving member 211C can drive the first lifting frame 211B to rise and fall. Four third driving members 211D are arranged in a rectangular four-point distribution on the first lifting frame 211B. The output end of the third driving member 211D has an insert plate. The four insert plates are used to jointly support at least two stacked receiving plates equipped with bridge bodies 910 (facing downwards), so that at least two receiving plates are placed in the first storage plate cavity 211A1. Among them, the second driving member 211C and the third driving member 211D are both cylinders, etc.

[0051] The process by which the first storage plate assembly 211 moves the single container plate located at the bottom to the support plate 213A located at the sixteenth position s16 is as follows: When the support plate 213A is located at the sixteenth position s16, the support plate 213A is located in the first storage plate cavity 211A1 and below the insert plate. The second drive member 211C drives the first lifting frame 211B to descend, and at least two container plates on the insert plate move to the support plate 213A. The four third drive members 211D drive the four insert plates to move and release the support of the container plate located at the bottom. The second drive member 211C drives the first lifting frame 211B to rise. The four third drive members 211D drive the four insert plates to move and support the container plate adjacent to the container plate located at the bottom. The second drive member 211C drives the first lifting frame 211B to rise, and the two container plates at the bottom separate, leaving the container plate located at the bottom on the support plate 213A located at the sixteenth position s16.

[0052] The conveyor bridge frame assembly 214 includes a fourth drive member 214A, a fifth drive member 214B, a first clamp 214C, a conveyor bridge 214D, a second conveyor belt assembly 214E, two sixth drive members 214F, and two seventh drive members 214G, as shown in the reference. Figure 1A conveyor bridge 214D is mounted on the frame 100 and has the aforementioned conveyor bridge channel. A fourth drive member 214A is mounted on the frame 100, and a fifth drive member 214B is mounted at the output end of the fourth drive member 214A. The fourth drive member 214A can drive the fifth drive member 214B to move laterally. A first clamp 214C is mounted at the output end of the fifth drive member 214B and is used to clamp the downward-facing bridge body 910. The fifth drive member 214B can drive the first clamp 214C to move up and down. The conveyor bridge 214D is equipped with an anti-detachment block. A second conveyor belt assembly 214E is mounted on... The conveyor bridge 214D and the second conveyor belt assembly 214E are capable of conveying the bridge body 910 of the bridge body channel from the twentieth position s20 to the nineteenth position s19, so that the bridge body 910 abuts against the anti-detachment block. The sixth drive member 214F is provided on the conveyor bridge 214D, and the output ends of the two sixth drive members 214F can be moved to above the two ends of the bridge body 910 at the nineteenth position s19, respectively. The seventh drive member 214G is provided on the conveyor bridge 214D, and the output ends of the two seventh drive members 214G can be moved to above the two ends of the bridge body 910 at the twentieth position s20, respectively. Among them, the fourth drive member 214A is configured as a linear module, etc.; the first clamp 214C is configured as a pneumatic gripper, etc.; the fifth drive member 214B, the sixth drive member 214F, and the seventh drive member 214G are all configured as cylinders, etc.; the structure and working principle of the second conveyor belt assembly 214E are the same as those of the first conveyor belt assembly, so they will not be described again here.

[0053] The working process of the bridge frame assembly 214 is as follows: the first clamp 214C clamps the bridge body 910 on the receiving plate at the seventeenth position s17; the fifth drive member 214B drives the clamped bridge body 910 to rise and fall; the fourth drive member 214A drives the clamped bridge body 910 to move laterally, so that the clamped bridge body 910 moves to the twentieth position s20; the output ends of the two seventh drive members 214G are respectively moved above the two ends of the bridge body 910 at the twentieth position s20; and the second conveyor belt assembly 214E transports the bridge body 910 at the twentieth position s20 to the nineteenth position s19.

[0054] When the bridge body 210 is placed at the nineteenth position s19, the output ends of the two sixth drive members 214F are respectively positioned above the two ends of the bridge body 910. If the first removal component 320 removes the bridge body 910 at the nineteenth position s19, the output ends of the two sixth drive members 214F are respectively moved away from the two ends of the bridge body 910.

[0055] The second storage rack assembly 212 includes a second storage rack 212A, a second lifting frame 212B, an eighth drive component 212C, and four hinge plates 212D. (Refer to...) Figure 2A second storage tray frame 212A is mounted on the frame 100, and the second storage tray frame 212A has a second storage tray cavity 212A1. A second lifting frame 212B is slidably mounted on the frame 100, and the second lifting frame 212B is located below the second storage tray cavity 212A1. An eighth driving member 212C is mounted on the frame 100, and the output end of the eighth driving member 212C is connected to the second lifting frame 212B. The eighth driving member 212C can drive the second lifting frame 212B to rise and fall. Four hinge plates 212D are rotatably connected to the frame 100 in a rectangular four-point distribution. Among them, the hinge plates 212D have a vertical state and a horizontal state. The horizontal hinge plate 212D can support the receiving plate. The eighth driving member 212C is configured as a cylinder, etc.

[0056] The working process of the second storage plate frame group 212 is as follows: When the support plate 213A is in the eighteenth position s18, the support plate 213A is located in the second storage plate cavity 212A1 and below the hinge plate 212D. The eighth driving member 212C drives the second lifting frame 212B to rise. The second lifting frame 212B supports and lifts the receiving plate on the support plate 213A. The lifted receiving plate drives the hinge plate 212D to rotate to a vertical state. When the receiving plate moves to a preset height above the hinge plate 212D, the hinge plate 212D returns to a horizontal state under the action of gravity. The eighth driving member 212C drives the second lifting frame 212B to fall, so that the receiving plate on the second lifting frame 212B is supported by the four hinge plates 212D in a horizontal state. At this time, the receiving work of the receiving plate on the support plate 213A in the eighteenth position s18 can be completed.

[0057] The bridge conveyor cover mechanism 220 includes a first vibratory feeder 221, a bridge conveyor cover frame 222, a bridge pick-up cover plate 223, and a ninth driving component 224, as shown in the figure. Figure 3 and Figure 4 The first vibratory plate 221, the bridge conveyor cover 222, and the ninth drive unit 224 are all located on the frame 100. The bridge pick-up cover 223 is connected to the output end of the ninth drive unit 224. The bridge pick-up cover 223 is provided with a bridge pick-up cover channel 223A. The bridge conveyor cover 222 is provided with a bridge conveyor cover channel. The inlet of the bridge conveyor cover channel is connected to the outlet of the first vibratory plate 221. The ninth drive unit 224 can drive the bridge pick-up cover 223 to move laterally, so that the bridge pick-up cover channel 223A connects to the outlet of the bridge conveyor cover channel, or so that the bridge pick-up cover 223 closes the outlet of the bridge conveyor cover channel.

[0058] The process of the bridge cover conveying mechanism 220 outputting the bridge cover 920 is as follows: the bridge cover 920 on the first vibrating plate 221 moves to the bridge cover taking channel 223A through the bridge cover conveying channel. The ninth driving member 224 drives the bridge cover taking plate 223 to move laterally. The bridge cover taking plate 223 closes the outlet of the bridge cover conveying channel. The single bridge cover 920 located in the bridge cover taking channel 223A is misaligned with the outlet of the bridge cover conveying channel to realize the operation of outputting the bridge cover 920.

[0059] The O-ring feeding mechanism 230 includes a second vibratory plate 231, an O-ring feeding frame 232, an O-ring strip taking mechanism 233, and a tenth driving member 234, as shown in the figure. Figure 8 , Figure 9 as well as Figure 11 The second vibratory plate 231, the O-ring conveyor 232, and the tenth drive unit 234 are all located on the frame 100. The O-ring strip 233 is connected to the output end of the tenth drive unit 234. The O-ring strip 233 is provided with a ring-taking groove 233A. The O-ring conveyor 232 is provided with an O-ring conveying channel. The inlet of the O-ring conveying channel is connected to the outlet of the second vibratory plate 231. The tenth drive unit 224 can drive the O-ring strip 233 to move laterally, so that the ring-taking groove 233A connects to the outlet of the O-ring conveying channel, or so that the O-ring strip 233 closes the outlet of the O-ring conveying channel.

[0060] It is understandable that the output working principle of the O-ring conveying mechanism 230 is the same as that of the bridge cover conveying mechanism 220, so it will not be described again here.

[0061] In this embodiment, refer to Figure 11 The O-ring feeder 232 is equipped with an eleventh driving member 235. The output end of the eleventh driving member 235 is equipped with an insertion block 235A. The eleventh driving member 235 can drive the insertion block 235A to rise and fall. When a single O-ring 930 enters the ring-taking slot 233A, the eleventh driving member 235 drives the insertion block 235A to move down and insert the O-ring 930 at the outlet of the O-ring feeder channel, thereby restricting the O-rings 930 from entering the ring-taking slot 233A.
