[0016] Wherein, the insertion rod on the inner wall of the fixing frame is slidably connected inside the thread groove.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, when the feeding rod moves downward and starts to clamp the nut, the bottoms of the multiple arc-shaped spring plates will contact the surface of the spring ring first. Since the tops of the arc-shaped spring plates are fixedly connected to the limit rod through the connecting ring, when the feeding rod continues to move downward, the multiple arc-shaped spring plates will be squeezed downward. After the arc-shaped spring plates are squeezed, the bottoms of the arc-shaped spring plates will expand outward on the tops of the spring ring and the hollow plate. When the bottoms of the multiple arc-shaped spring plates expand, the expanded arc-shaped spring plates will pull the rubber ring through the C-shaped frame. After being pulled, the rubber ring will form an expanded deformation and be sleeved on the surface of the nut. At the same time, when the multiple arc-shaped spring plates expand outward, the nut can be placed in the middle of the multiple arc-shaped spring plates. At the same time, when the arc-shaped spring plates expand outward, when the feeding rod moves upward, the multiple arc-shaped spring plates The plate will shrink inward. When the arc-shaped spring plate shrinks inward, the shrinkage of the arc-shaped spring plate will pull the connecting plate downward inside the hollow ring through the middle plate. When the piston ring moves downward, the downward movement of the piston ring will squeeze the gas inside the hollow ring and enter the inflatable bag through the connecting pipe to expand it. When the inflatable bag is expanding, the shrinkage of the arc-shaped spring plate will clamp the nut through the inflatable bag. Then, when the arc-shaped spring plate is reset and contracted, the nut can be placed between multiple arc-shaped spring plates to cover and position the rivet nut, so that the rivet nut remains in the correct position, which can reduce the tilt or misalignment of the rivet nut caused by the shaking or vibration generated when the feeding rod moves downward or rotates, and improve the alignment accuracy of the rivet nut and the alignment hole on the window, thereby improving the assembly quality of the sunroof and improving the feeding and installation efficiency.

[0019] 2. In the present invention, when the arc-shaped spring plate expands outward, the expansion of the arc-shaped spring plate will pull the rubber ring downward through the C-shaped frame and pull the rubber ring to expand. When the rubber ring moves downward and expands, the downward movement of the rubber ring will drive multiple curved adsorption tubes to move downward synchronously and rotate at the bottom of the inflation tube as the rubber ring expands. Then, when the loading rod drives the fixed tube to move upward, the rubber ring will recover through its own elasticity. When the rubber ring recovers, it will drive multiple curved adsorption tubes to shrink and move upward. When multiple curved adsorption tubes move upward, the upward movement of multiple curved adsorption tubes will push spring ring 2 through the inflation tube so that spring ring 2 slides upward inside the C-shaped ring. When spring ring 2 slides upward, the sliding of spring ring 2 will An adsorption force is generated between the bottom of the second spring ring and the C-ring. At this time, the formation of the adsorption force will adsorb the curved adsorption tube through the middle tube. Since multiple curved adsorption tubes will be covered on the surface of the nut as they shrink with the recovery of the rubber ring, when the adsorption force adsorbs the inside of the curved adsorption tube, the adsorption force will be transmitted to the nut through the curved adsorption tube and adsorb the surface of the nut. At the same time, when the curved adsorption tube is covered on the surface of the nut, a protective layer will be formed on the surface of the nut. Through the adsorption force, the large vibration of the nut during the feeding and moving process can be reduced. The adsorption force can prevent the rivet nut from being separated from the inside of the arc spring plate due to inertia, thereby ensuring the smooth progress of the feeding process and improving the reliability and stability of the feeding process.

[0020] 3. In the present invention, when the multiple inflatable tubes drive the spring ring 2 to move upward inside the C-shaped ring, the upward movement of the spring ring 2 will drive the fixing frame to move upward synchronously, and when the fixing frame moves upward, the internal insertion rod will slide in the thread groove on the surface of the gear cylinder, and when the fixing frame moves upward and drives the insertion rod to slide inside the thread groove, the extrusion force generated on the thread groove by the sliding of the insertion rod will drive the gear cylinder to rotate, and when the gear cylinder rotates, it will drive the gear shaft to rotate, and when the gear shaft rotates, it will drive the rubber shaft to rotate. Since the end of the rubber shaft away from the gear shaft is fixed to the bottom of the C-shaped ring, when the rubber shaft rotates, the rubber shaft will produce a twisting and shortening change, and when the rubber shaft shortens, the twisting and shortening change of the rubber shaft will shrink inward on the surfaces of multiple arc-shaped spring plates, and when the rubber shaft shrinks, the rubber shaft The contraction will squeeze the middle parts of multiple arc-shaped spring plates, causing the middle parts of the arc-shaped spring plates to contract inward, and at the same time, it can also cause the middle parts of the arc-shaped spring plates to gather toward the center. Afterwards, the change of the rubber shaft will also produce an upward pulling force on the arc-shaped spring plates, making the arc-shaped spring plates cover the rivet nuts more evenly and powerfully, which can further correct the possible inclination of the rivet nuts and evenly distribute the pressure when releasing the nuts. At the same time, through the contraction and pulling force of the rubber shaft, when the windows are aligned and installed, the inclination of multiple arc-shaped spring plates caused by the uneven structure of the window surface can be reduced, and the inclination of the nuts caused by the inclination of the arc-shaped spring plates during the installation of the windows can be reduced. This reduces the nut installation problems caused by inclination or uneven pressure and improves the installation efficiency.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The top of the arc-shaped spring plate 402 is fixedly connected to the limit rod 303 through the connecting ring 401. When the feeding rod 106 continues to move downward, multiple arc-shaped spring plates 402 will be squeezed downward. After being squeezed, the bottom of the arc-shaped spring plates 402 will expand outward on the top of the spring ring 205 and the hollow plate 204. When the bottoms of the multiple arc-shaped spring plates 402 expand, the expanded arc-shaped spring plates 402 will pull the rubber ring 404 through the C-shaped frame 403.

[0039] The interior of the fixed cylinder 301 is provided with an auxiliary mechanism 5, which includes an intermediate plate 501 rotatably connected to the side wall of the arc-shaped spring plate 402, and the end of the intermediate plate 501 away from the arc-shaped spring plate 402 is rotatably connected to a connecting plate 502, and the top of the connecting plate 502 penetrates the bottom inner wall of the hollow ring 302 and extends to the outside, and the extended ends of several connecting plates 502 are fixedly connected to piston rings 503, and the bottom of the piston ring 503 is provided with several connecting pipes, and the end of the connecting pipe away from the hollow ring 302 penetrates the side wall of the arc-shaped spring plate 402 and extends to the outside, and the extended end of the connecting pipe An inflatable bag 504 is fixedly connected, and one end of the connecting pipe close to the piston ring 503 is fixedly connected to the hollow ring 302.

[0040] An adsorption mechanism 6 is provided inside the fixed cylinder 301, and the adsorption mechanism 6 includes a C-shaped ring 601 fixedly connected to the bottom of several limiting rods 303, a spring ring 2 602 is slidably connected inside the C-shaped ring 601, a fixing frame 603 is fixedly connected to the top of the spring ring 2 602, an insertion rod is fixedly connected to the inner wall of the fixing frame 603, and one end of the spring ring 2 602 away from the fixing frame 603 is fixedly connected to several inflation tubes 604, the rubber ring 404 will recover through its own elasticity, and when the rubber ring 404 recovers, it will drive multiple curved adsorption tubes 605 to shrink and move upward, and when the multiple curved adsorption tubes 605 move upward, the upward movement of the multiple curved adsorption tubes 605 will push the spring ring 2 602 through the inflation tube 604 so that the spring ring 2 602 slides upward inside the C-shaped ring 601.

[0041] One end of the inflation tube 604 away from the fixed frame 603 penetrates through the bottom outer wall of the C-shaped ring 601 and extends to the outside. The outer surface of the extended end of the inflation tube 604 is rotatably connected with a curved adsorption tube 605. The outer surface of the inflation tube 604 is fixedly connected with an intermediate tube. The curved adsorption tube 605 is connected to the inflation tube 604 through the intermediate tube. The curved adsorption tube 605 is made of flexible material. One end of the curved adsorption tube 605 away from the inflation tube 604 is rotatably connected to the side wall of the rubber ring 404. When the spring ring 2 602 slides upward, the sliding of the spring ring 2 602 will generate an adsorption force between the bottom of the spring ring 2 602 and the C-shaped ring 601. At this time, the formation of the adsorption force will adsorb the curved adsorption tube 605 through the intermediate tube. Because multiple curved adsorption tubes 605 shrink as the rubber ring 404 recovers, they will cover the surface of the nut.

[0042] A rotating mechanism 7 is provided inside the fixed frame 603, and the rotating mechanism 7 includes a gear cylinder 701 rotatably connected to the top of a plurality of limit rods 303, and a threaded groove is provided on the outer surface of the gear cylinder 701, and a gear shaft 702 is meshedly connected to the outer surface of the gear cylinder 701. When the fixed frame 603 moves upward, the internal insertion rod will slide in the threaded groove on the surface of the gear cylinder 701, and when the fixed frame 603 moves upward and drives the insertion rod to slide inside the threaded groove, the gear cylinder 701 will be driven to rotate by the extrusion force generated by the sliding of the insertion rod on the threaded groove, and the gear cylinder 701 will drive the gear shaft 702 to rotate when rotating, and the gear shaft 702 will drive the rubber shaft 703 to rotate when rotating.

[0043] The top of the gear shaft 702 is rotatably connected to the top inner wall of the fixed cylinder 301, the bottom of the gear shaft 702 is fixedly connected to a rubber shaft 703, the outer surface of the rubber shaft 703 is rotatably connected to the side walls of a plurality of arc-shaped spring plates 402, and one end of the rubber shaft 703 away from the gear shaft 702 is fixedly connected to the bottom outer wall of the C-shaped ring 601;

[0044] Among them, the insertion rod on the inner wall of the fixing frame 603 is slidably connected to the inside of the threaded groove. Since the end of the rubber shaft 703 away from the gear shaft 702 is fixed to the bottom of the C-shaped ring 601, when the rubber shaft 703 rotates, the rubber shaft 703 will be twisted and shortened. When the rubber shaft 703 is shortened, the twisting and shortening of the rubber shaft 703 will shrink inward on the surface of multiple arc-shaped spring plates 402.

[0045] When in use, first connect the delivery pipe 203 to the external material conveying device, then place the car window that needs to be loaded on the placement plate 102, and then you can control the sliding adjustment of the placement plate 102 by starting the electric push rod 101. When loading is needed, start the electric push rod 201. When working, the electric push rod 201 will drive the delivery pipe 203 and the hollow plate 204 to move to the bottom of the loading rod 106 through the L plate 202. Then, the limit mechanism 3 is installed on the surface of the loading rod 106 by bolts. Then, the rivet nut that needs to be loaded will slide onto the lifting block 207 through the delivery pipe 203, and then start the hydraulic rod 104 to make it descend. When the hydraulic rod 104 descends, the arc-shaped spring plate 402 will squeeze the spring ring 205, and the spring ring 205 will be pushed through the hollow plate after being squeezed. The hollow plate 206 causes the hollow plate 206 to deflect on the limit frame. When the hollow plate 206 deflects, the deflected hollow plate 206 will drive the lifting block 207 to move upward. When the lifting block 207 moves upward, it will drive the nut to move to the top of the hollow plate 204, and then when the loading rod 106 moves downward, the nut will be clamped, and then the electric push rod 201 and the hydraulic rod 104 are started again, so that the hydraulic rod 104 moves up a little distance first to disengage the loading rod 106 from the hollow plate 204, and then when the electric push rod 201 works, the L plate 202 can drive the hollow plate 204 to reset and disengage from the loading rod 106, and then continue to start the hydraulic rod 104, so that the hydraulic rod 104 drives the loading rod 106 and the nut to connect with the car window, and the loading work is completed.

[0046] When the feeding rod 106 moves downward and starts to clamp the nut, the bottoms of the multiple arc-shaped spring plates 402 will contact the surface of the spring ring 205 first. Since the tops of the arc-shaped spring plates 402 are fixedly connected to the limit rod 303 through the connecting ring 401, when the feeding rod 106 continues to move downward, the multiple arc-shaped spring plates 402 will be squeezed downward. After being squeezed, the bottoms of the arc-shaped spring plates 402 will expand outwards on the tops of the spring ring 205 and the hollow plate 204. When the bottom of the multiple arc-shaped spring plates 402 expands, the expanded arc-shaped spring plates 402 will pull the rubber ring 404 through the C-shaped frame 403. After being pulled, the rubber ring 404 will form an expanded deformation and make the rubber ring 404 sleeved on the surface of the nut. At the same time, when the multiple arc-shaped spring plates 402 expand outward, the nut can be placed in the middle of the multiple arc-shaped spring plates 402. At the same time, when the arc-shaped spring plates 402 expand outward, when the feeding rod 106 moves upward, The multiple arc-shaped spring plates 402 will shrink inwardly. When the arc-shaped spring plates 402 shrink inwardly, the shrinkage of the arc-shaped spring plates 402 will pull the connecting plate 502 to move downward inside the hollow ring 302 through the middle plate 501. When the piston ring 503 moves downward, the downward movement of the piston ring 503 will squeeze the gas inside the hollow ring 302 and enter the inflatable bag 504 through the connecting pipe to expand it. When the inflatable bag 504 expands, the shrinkage of the arc-shaped spring plates 402 will clamp the nut through the inflatable bag 504. Then, when the arc-shaped spring plates 402 are reset and shrunk, the nut can be placed between the multiple arc-shaped spring plates 402 to cover and position the rivet nut, so that the rivet nut is kept in the correct position, which can reduce the tilt or misalignment of the rivet nut caused by the shaking or vibration generated when the feeding rod 106 moves downward or rotates, and improve the alignment accuracy of the rivet nut and the alignment hole on the vehicle window, thereby improving the assembly quality of the sunroof and improving the feeding and installation efficiency.

[0047] When the arc spring plate 402 expands outward, the expansion of the arc spring plate 402 will pull the rubber ring 404 downward through the C-shaped frame 403 and pull the rubber ring 404 to expand. When the rubber ring 404 moves downward and expands, the downward movement of the rubber ring 404 will drive the multiple curved adsorption tubes 605 to move downward synchronously and rotate at the bottom of the inflation tube 604 as the rubber ring 404 expands. Then, when the loading rod 106 drives the fixing cylinder 301 to move upward, the rubber ring 404 will recover through its own elasticity. When the rubber ring 404 recovers, it will drive the multiple curved adsorption tubes 605 to shrink and move upward. When the multiple curved adsorption tubes 605 move upward, the upward movement of the multiple curved adsorption tubes 605 will push the spring ring 2 602 through the inflation tube 604 so that the spring ring 2 602 slides upward inside the C-shaped ring 601. When sliding upward, the sliding of the spring ring 2 602 will generate an adsorption force between the bottom of the spring ring 2 602 and the C-shaped ring 601. At this time, the formation of the adsorption force will adsorb the curved adsorption tube 605 through the middle tube. Since the multiple curved adsorption tubes 605 will be covered on the surface of the nut when they shrink as the rubber ring 404 recovers, when the adsorption force adsorbs the inside of the curved adsorption tube 605, the adsorption force will be transmitted to the nut through the curved adsorption tube 605 and adsorb the surface of the nut. At the same time, when the curved adsorption tube 605 is covered on the surface of the nut, a protective layer will be formed on the surface of the nut. Through the adsorption force, the nut can reduce the large vibration generated during the feeding movement. The adsorption force can prevent the rivet nut from being separated from the inside of the arc spring plate 402 due to inertia, ensuring the smooth progress of the feeding process and improving the reliability and stability of the feeding process.

[0048] When the multiple inflatable tubes 604 drive the spring ring 2 602 to move upward inside the C-shaped ring 601, the upward movement of the spring ring 2 602 will drive the fixing frame 603 to move upward synchronously. When the fixing frame 603 moves upward, it will slide in the thread groove on the surface of the gear cylinder 701 through the internal insertion rod. When the fixing frame 603 moves upward and drives the insertion rod to slide inside the thread groove, the extrusion force generated on the thread groove when the insertion rod slides drives the gear cylinder 701 to rotate. When the gear cylinder 701 rotates, it drives the gear shaft 702 to rotate. When the gear shaft 702 rotates, it drives the rubber shaft 703 to rotate. Since the end of the rubber shaft 703 away from the gear shaft 702 is fixed to the bottom of the C-shaped ring 601, when the rubber shaft 703 rotates, the rubber shaft 703 will produce a change of twisting and shortening. When the rubber shaft 703 shortens, the change of twisting and shortening of the rubber shaft 703 will shrink inward on the surface of the multiple arc-shaped spring plates 402. When the rubber shaft 703 contracts, the contraction of the rubber shaft 703 will squeeze the middle parts of the multiple arc-shaped spring plates 402, causing the middle parts of the arc-shaped spring plates 402 to contract inward, and at the same time, it can also cause the middle parts of the arc-shaped spring plates 402 to gather toward the center. After that, the change of the rubber shaft 703 will also generate an upward pulling force on the arc-shaped spring plates 402, so that the arc-shaped spring plates 402 can cover the rivet nuts more evenly and powerfully, and can further correct the possible inclination of the rivet nuts, and evenly distribute the pressure when releasing the nuts. At the same time, through the contraction and pulling force of the rubber shaft, when the window is aligned and installed, the situation that the multiple arc-shaped spring plates 402 are tilted when they are aligned with the window surface due to the uneven structure of the window surface can be reduced, and the situation that the nut is tilted when the window is aligned and installed due to the inclination of the arc-shaped spring plates 402 can be reduced, and the nut installation problems caused by inclination or uneven pressure can be reduced, thereby improving the installation efficiency.
