Description

Technical Field

[0001] The present invention relates to the technical field of automotive component installation, and specifically relates to a rivet nut alignment and feeding device for an automotive sunroof. Background Technique

[0002] In the field of automotive manufacturing, with the continuous increase in automotive production and the increasing demand for production efficiency, automated production has become an inevitable trend. As an important component of an automobile, the assembly process of an automotive sunroof also needs to achieve efficient and precise automation;

[0003] When installing a sunroof, it is necessary to install rivet nuts on the sunroof. Generally, the existing installation method is basically to use a fixture with an adsorption device to adsorb the nut through the adsorption force and align and install it on the sunroof. Since the nut has many edges and corners and mostly lies sideways in the conveying tray, when the fixture with the adsorption device adsorbs and clamps the nut, it is very easy for the nut to tilt or be misaligned on the fixture during adsorption, making it difficult to ensure the accuracy between the nut and the alignment hole, and easily causing the nut to deviate during alignment installation, affecting the installation efficiency of alignment feeding and installation. Summary of the Invention

[0011] Further, an auxiliary mechanism is arranged inside the fixed cylinder. The auxiliary mechanism includes an intermediate plate rotatably connected to the side wall of the arc-shaped elastic plate. One end of the intermediate plate away from the arc-shaped elastic plate is rotatably connected with a connecting plate.

[0012] Further, an adsorption mechanism is arranged inside the fixed cylinder. The adsorption mechanism includes a C-shaped ring fixedly connected to the bottoms of several limiting rods.

[0014] Further, a rotating mechanism is arranged inside the fixed frame. The rotating mechanism includes a toothed cylinder rotatably connected to the tops of several limiting rods.

[0015] Further, the top of the tooth shaft is rotatably connected to the inner wall of the top of the fixed cylinder. A rubber shaft is fixedly connected to the bottom of the tooth shaft.

[0016] Among them, the insertion rod on the inner wall of the fixed frame is slidably connected inside the threaded 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 elastic plates will first contact the surface of the spring ring. Since the tops of the arc-shaped elastic plates are fixedly connected to the limiting rods through the connecting rings, when the feeding rod continues to move downward, it will squeeze the multiple arc-shaped elastic plates downward. After being squeezed, the bottoms of the arc-shaped elastic plates will expand outward on the tops of the spring ring and the hollow plate. When the bottoms of the multiple arc-shaped elastic plates expand, the expanded arc-shaped elastic plates will pull the rubber ring through the C-shaped frame. After being pulled, the rubber ring will form an expanded deformation and the rubber ring will be sleeved on the surface of the nut. At the same time, when the multiple arc-shaped elastic plates expand outward, the nut can be located in the middle of the multiple arc-shaped elastic plates. When the arc-shaped elastic plates expand outward, when the feeding rod moves upward, the multiple arc-shaped elastic plates will contract inward. When the arc-shaped elastic plates contract inward, the contraction of the arc-shaped elastic plates will pull the connecting plate to move 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 and cause it to expand. When the inflatable bag expands, the contraction of the arc-shaped elastic plates will clamp the nut through the inflatable bag. After that, when the arc-shaped elastic plates return and contract, the nut can be located between the multiple arc-shaped elastic plates to wrap and position the rivet nut, keeping the rivet nut in the correct position, reducing the situation of the rivet nut tilting or misaligning caused by the shaking or vibration generated when the feeding rod moves downward or rotates, improving the alignment accuracy between the rivet nut and the alignment hole on the window, thereby improving the assembly quality of the skylight and increasing the feeding and installation efficiency.

[0019] 2. In the present invention, when the arc-shaped elastic plate expands outwards, the expansion of the arc-shaped elastic plate will pull the rubber ring downward through the C-shaped frame and cause the rubber ring to expand. When the rubber ring moves downward and expands, the downward movement of the rubber ring will drive a plurality of curved adsorption tubes to move downward synchronously and rotate at the bottom of the inflation tube as the rubber ring expands. Then, when the feeding rod drives the fixed cylinder to move upward, the rubber ring will recover by its own elasticity. When the rubber ring recovers, it will drive a plurality of curved adsorption tubes to contract and move upward. When the plurality of curved adsorption tubes move upward, the upward movement of the plurality of curved adsorption tubes will push the second spring ring through the inflation tube, causing the second spring ring to slide upward inside the C-shaped ring. When the second spring ring slides upward, an adsorption force will be generated between the bottom of the second spring ring and the C-shaped ring. At this time, the formation of the adsorption force will adsorb the curved adsorption tube through the intermediate tube. Since the plurality of curved adsorption tubes will wrap around the surface of the nut when contracting 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 wraps around the surface of the nut, a protective layer will be formed on the surface of the nut and through the adsorption force, it can reduce the large vibration generated during the feeding movement of the nut. The adsorption force can prevent the rivet nut from separating from the inside of the arc-shaped elastic plate due to inertia, 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 multiple inflation tubes drive the second spring ring to move upward inside the C-shaped ring, the upward movement of the second spring ring will drive the fixing bracket to move upward synchronously. When the fixing bracket moves upward, the insertion rod inside it will slide in the threaded groove on the surface of the toothed cylinder. When the fixing bracket moves upward and drives the insertion rod to slide inside the threaded groove, the extrusion force generated by the insertion rod during sliding will drive the toothed cylinder to rotate. When the toothed cylinder rotates, it will drive the toothed shaft to rotate. When the toothed shaft rotates, it will drive the rubber shaft to rotate. Since one end of the rubber shaft far from the toothed shaft is fixed to the bottom of the C-shaped ring, when the rubber shaft rotates, the rubber shaft will undergo a change of being screwed and shortened. When the rubber shaft shortens, the change of the rubber shaft being screwed and shortened will cause inward contraction on the surfaces of multiple arc-shaped elastic plates. When the rubber shaft contracts, the contraction of the rubber shaft will squeeze the middle parts of the multiple arc-shaped elastic plates, causing the middle parts of the arc-shaped elastic plates to contract inward and at the same time promoting the middle parts of the arc-shaped elastic plates to gather towards the center. Then, the change of the rubber shaft will also generate an upward pulling force on the arc-shaped elastic plates, making the arc-shaped elastic plates wrap the rivet nut more evenly and powerfully, which can further correct the possible inclination of the rivet nut, evenly distribute the pressure when releasing the nut, and at the same time, through the contraction and pulling force of the rubber shaft, when installing the window in place, it can reduce the situation where the multiple arc-shaped elastic plates are inclined when contacting the window surface due to the uneven structure of the window surface, and reduce the situation where the nut is inclined during installation with the window due to the inclination of the arc-shaped elastic plates when installing the window in place, reducing the nut installation problems caused by inclination or uneven pressure and improving the installation efficiency.

[0021] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

A first electric push rod 101 is fixedly connected to the top of the main body 1. The output end of the first electric push rod 101 is fixedly connected to a placement plate 102. A support frame 103 is fixedly connected to one side of the main body 1 close to the first electric push rod 101. A hydraulic rod 104 is fixedly connected to the top of the support frame 103. The output end of the hydraulic rod 104 penetrates through the top inner wall of the support frame 103 and extends to the outside. A sliding plate 105 is fixedly connected to the outer surface of the extended end of the hydraulic rod 104. The side wall of the sliding plate 105 is slidably connected to the side wall of the support frame 103. The extended end of the hydraulic rod 104 is fixedly connected to a feeding rod 106. It also includes;

[0035] A feeding mechanism 2, the feeding mechanism 2 includes a second electric push rod 201 fixedly connected to the outer wall on the right side of the support frame 103. The output end of the second electric push rod 201 is fixedly connected to an L-shaped plate 202. A feeding pipe 203 is fixedly connected to one side of the L-shaped plate 202 close to the second electric push rod 201. One end of the feeding pipe 203 away from the second electric push rod 201 is fixedly connected to a hollow plate 204. The feeding pipe 203 is in communication with the hollow plate 204. Two springs are fixedly connected to the bottom inner wall of the hollow plate 204;

[0036] A limiting mechanism 3, the limiting mechanism 3 includes a fixed cylinder 301 slidably connected to the outer surface of the feeding rod 106. A hollow ring 302 is fixedly connected to the inner wall of the fixed cylinder 301. A hollow cylinder is fixedly connected to the top inner wall of the fixed cylinder 301. A number of limiting rods 303 are fixedly connected to the outer surface of the hollow cylinder. First, connect the feeding pipe 203 to an external material conveying device. Then, place the window to be fed onto the placement plate 102. After that, the sliding adjustment of the placement plate 102 can be controlled by starting the first electric push rod 101. When feeding is required, start the second electric push rod 201. When the second electric push rod 201 is working, it will drive the feeding pipe 203 and the hollow plate 204 to move to the bottom of the feeding rod 106 through the L-shaped plate 202. Then, install the limiting mechanism 3 on the surface of the feeding rod 106 through bolts. Subsequently, the rivet nuts to be fed will slide down the feeding pipe 203 onto the lifting block 207. Then, start the hydraulic rod 104 to make it descend. When the hydraulic rod 104 descends, the arc-shaped elastic plate 402 will squeeze the spring ring 205.

[0037] The top of the spring penetrates through to the top outer wall of the hollow plate 204 and extends to the outside. The extended ends of the two springs are fixedly connected with a spring ring 205. The bottom of the spring ring 205 is rotatably connected with two hollow plates. One end of the hollow plate away from the spring ring 205 is rotatably connected with a second hollow plate 206. A limiting frame is slidably connected inside the second hollow plate 206. The bottom of the limiting frame is fixedly connected with the bottom inner wall of the hollow plate 204. A lifting block 207 is rotatably connected between the two second hollow plates 206. A round hole is provided at the top of the hollow plate 204. After the spring ring 205 is squeezed, it will push the second hollow plate 206 through the hollow plate, causing the second hollow plate 206 to deflect on the limiting frame. When the second hollow plate 206 deflects, the deflected second 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. Then, when the feeding rod 106 moves downward, the nut will be clamped.

[0038] An expansion mechanism 4 is arranged inside the fixed cylinder 301. The expansion mechanism 4 includes a connecting ring 401 fixedly connected between two limiting rods 303. An arc-shaped elastic plate 402 is fixedly connected to the outer surface of the connecting ring 401. One end of the arc-shaped elastic plate 402 away from the connecting ring 401 is rotatably connected with a C-shaped frame 403. A rubber ring 404 is slidably connected between several C-shaped frames 403. When the feeding rod 106 moves downward and starts to clamp the nut, the bottoms of multiple arc-shaped elastic plates 402 will first come into contact with the surface of the spring ring 205. Since the top of the arc-shaped elastic plate 402 is fixedly connected with the limiting rod 303 through the connecting ring 401, then when the feeding rod 106 continues to move downward, it will squeeze multiple arc-shaped elastic plates 402 downward. After the arc-shaped elastic plate 402 is squeezed, its bottom will expand outward on the top of the spring ring 205 and the hollow plate 204. When the bottoms of multiple arc-shaped elastic plates 402 expand, the expanded arc-shaped elastic plates 402 will pull the rubber ring 404 through the C-shaped frame 403.

[0039] Inside the fixed cylinder 301, there is an auxiliary mechanism 5. The auxiliary mechanism 5 includes an intermediate plate 501 rotatably connected to the side wall of the arc-shaped elastic plate 402. One end of the intermediate plate 501 away from the arc-shaped elastic plate 402 is rotatably connected to a connecting plate 502. The top of the connecting plate 502 penetrates through the bottom inner wall of the hollow ring 302 and extends to the outside. The extended ends of several connecting plates 502 are fixedly connected to a piston ring 503. At the bottom of the piston ring 503, there are several connecting pipes. The end of the connecting pipe away from the hollow ring 302 penetrates through the side wall of the arc-shaped elastic plate 402 and extends to the outside. The extended end of the connecting pipe is fixedly connected to an inflatable bag 504. One end of the connecting pipe close to the piston ring 503 is fixedly connected to the hollow ring 302. The hollow ring 302 is in communication with the connecting pipe. When the arc-shaped elastic plate 402 contracts, it will pull the connecting plate 502 to move downward inside the hollow ring 302 through the intermediate 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, causing it to expand. When the inflatable bag 504 expands, the contraction of the arc-shaped elastic plate 402 will clamp the nut through the inflatable bag 504.

[0040] Inside the fixed cylinder 301, there is an adsorption mechanism 6. The adsorption mechanism 6 includes a C-shaped ring 601 fixedly connected to the bottoms of several limiting rods 303. Inside the C-shaped ring 601, there is a second spring ring 602 slidably connected. The top of the second spring ring 602 is fixedly connected to a fixing frame 603. Inside the inner wall of the fixing frame 603, there is a plug rod. One end of the second spring ring 602 away from the fixing frame 603 is fixedly connected to several air filling pipes 604. The rubber ring 404 will recover by its own elasticity. When the rubber ring 404 recovers, it will drive a plurality of curved adsorption pipes 605 to contract and move upward. When the plurality of curved adsorption pipes 605 move upward, the upward movement of the plurality of curved adsorption pipes 605 will push the second spring ring 602 through the air filling pipes 604, causing the second spring ring 602 to slide upward inside the C-shaped ring 601.

[0041] One end of the air filling pipe 604 away from the fixing 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 air filling pipe 604 is rotatably connected to a curved adsorption pipe 605. The outer surface of the air filling pipe 604 is fixedly connected to an intermediate pipe. The curved adsorption pipe 605 is in communication with the air filling pipe 604 through the intermediate pipe. The curved adsorption pipe 605 is made of a flexible material. One end of the curved adsorption pipe 605 away from the air filling pipe 604 is rotatably connected to the side wall of the rubber ring 404. When the second spring ring 602 slides upward, the sliding of the second spring ring 602 will generate an adsorption force between the bottom of the second spring ring 602 and the C-shaped ring 601. At this time, the formation of the adsorption force will adsorb the curved adsorption pipe 605 through the intermediate pipe. Since the plurality of curved adsorption pipes 605 will wrap around the surface of the nut when contracting along with the recovery of the rubber ring 404.

[0042] The interior of the fixing frame 603 is provided with a rotating mechanism 7. The rotating mechanism 7 includes a toothed cylinder 701 rotatably connected to the tops of a number of limiting rods 303. Thread grooves are formed on the outer surface of the toothed cylinder 701. A toothed shaft 702 is meshed and connected to the outer surface of the toothed cylinder 701. When the fixing frame 603 moves upward, the inner inserting rod will slide in the thread grooves on the surface of the toothed cylinder 701. When the fixing frame 603 moves upward to drive the inserting rod to slide inside the thread grooves, the extrusion force generated by the inserting rod during sliding will drive the toothed cylinder 701 to rotate. When the toothed cylinder 701 rotates, it will drive the toothed shaft 702 to rotate. When the toothed shaft 702 rotates, it will drive the rubber shaft 703 to rotate.

[0043] The top of the toothed shaft 702 is rotatably connected to the inner wall of the top of the fixed cylinder 301. The bottom of the toothed shaft 702 is fixedly connected with a rubber shaft 703. The outer surface of the rubber shaft 703 is rotatably connected to the side walls of a number of arc-shaped elastic plates 402. One end of the rubber shaft 703 away from the toothed shaft 702 is fixedly connected to the outer wall of the bottom of the C-shaped ring 601;

[0044] Among them, the inserting rod on the inner wall of the fixing frame 603 is slidably connected inside the thread grooves. Since one end of the rubber shaft 703 away from the toothed shaft 702 is fixed to the bottom of the C-shaped ring 601, when the rubber shaft 703 rotates, the rubber shaft 703 will change and become shorter by screwing. When the rubber shaft 703 becomes shorter, the change of the rubber shaft 703 becoming shorter by screwing will cause inward contraction on the surfaces of a number of arc-shaped elastic plates 402.

[0045] In use, first connect the material feeding pipe 203 to an external material conveying device, then place the window to be loaded onto the placement plate 102. After that, the sliding adjustment of the placement plate 102 can be controlled by starting the first electric push rod 101. When feeding is required, start the second electric push rod 201. When the second electric push rod 201 is working, it will drive the material feeding pipe 203 and the hollow plate 204 to move to the bottom of the feeding rod 106 through the L-shaped plate 202. Then, install the limiting mechanism 3 on the surface of the feeding rod 106 through bolts. Subsequently, the rivet nuts to be fed will slide down through the material feeding pipe 203 onto the lifting block 207. Then, start the hydraulic rod 104 to make it descend. When the hydraulic rod 104 descends, the arc-shaped elastic plate 402 will squeeze the spring ring 205. After being squeezed, the spring ring 205 will push the second hollow plate 206 through the hollow plate, causing the second hollow plate 206 to deflect on the limiting frame. When the second hollow plate 206 deflects, the deflected second 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 the top of the hollow plate 204. Then, when the feeding rod 106 moves downward, it will clamp the nut. Subsequently, start the second electric push rod 201 and the hydraulic rod 104 again, so that the hydraulic rod 104 first moves upward a certain distance to disengage the feeding rod 106 from the hollow plate 204. Then, when the second electric push rod 201 is working, the L-shaped plate 202 can drive the hollow plate 204 to reset and disengage from the feeding rod 106. Then, continue to start the hydraulic rod 104, so that the hydraulic rod 104 drives the feeding rod 106 and the nut to be connected to the window, completing the feeding work.

[0046] When the feeding rod 106 moves downward and starts to clamp the nut, the bottoms of the multiple arc-shaped elastic plates 402 will contact the surface of the spring ring 205 first. Since the tops of the arc-shaped elastic plates 402 are fixedly connected to the limiting rod 303 through the connecting ring 401, when the feeding rod 106 continues to move downward, it will squeeze the multiple arc-shaped elastic plates 402 downward. After being squeezed, the bottoms of the arc-shaped elastic plates 402 will expand outward on the tops of the spring ring 205 and the hollow plate 204. When the bottoms of the multiple arc-shaped elastic plates 402 expand, the expanded arc-shaped elastic 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 the rubber ring 404 will be sleeved on the surface of the nut. At the same time, when the multiple arc-shaped elastic plates 402 expand outward, the nut can be located in the middle of the multiple arc-shaped elastic plates 402. At the same time, when the arc-shaped elastic plates 402 expand outward, when the feeding rod 106 moves upward later, the multiple arc-shaped elastic plates 402 will contract inward. When the arc-shaped elastic plates 402 contract inward, the contraction of the arc-shaped elastic 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 and make it expand. When the inflatable bag 504 expands, the contraction of the arc-shaped elastic plates 402 will clamp the nut through the inflatable bag 504. After the arc-shaped elastic plates 402 are reset and contract, the nut can be located between the multiple arc-shaped elastic plates 402 to wrap and position the rivet nut, so that the rivet nut is kept in the correct position, which can reduce the situation that the rivet nut is inclined or misaligned due to the shaking or vibration generated when the feeding rod 106 moves downward or rotates, improve the alignment accuracy between the rivet nut and the alignment hole on the window, thereby improving the assembly quality of the skylight and increasing the feeding and installation efficiency.

[0047] When the arc-shaped elastic plate 402 expands outwards, the expansion of the arc-shaped elastic 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 multiple curved adsorption tubes 605 to move downward synchronously and rotate at the bottom of the air charging tube 604 as the rubber ring 404 expands. Then, when the feeding rod 106 drives the fixed cylinder 301 to move upward, the rubber ring 404 will recover by its own elasticity. When the rubber ring 404 recovers, it will drive multiple curved adsorption tubes 605 to contract and move upward. When multiple curved adsorption tubes 605 move upward, the upward movement of multiple curved adsorption tubes 605 will push the second spring ring 602 through the air charging tube 604, causing the second spring ring 602 to slide upward inside the C-shaped ring 601. When the second spring ring 602 slides upward, the sliding of the second spring ring 602 will generate an adsorption force between the bottom of the second spring ring 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. Since multiple curved adsorption tubes 605 will cover the surface of the nut when contracting with the recovery of the rubber ring 404, 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 covers the surface of the nut, a protective layer will be formed on the surface of the nut and through the adsorption force, it can reduce the large vibration generated during the feeding movement of the nut. The adsorption force can prevent the rivet nut from detaching from the inside of the arc-shaped elastic 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 multiple inflation tubes 604 drive the second spring ring 602 to move upward inside the C-ring 601, the upward movement of the second spring ring 602 will drive the fixed bracket 603 to move upward synchronously. When the fixed bracket 603 moves upward, it will slide through the internal insertion rod in the thread groove on the surface of the toothed cylinder 701. When the fixed bracket 603 moves upward and drives the insertion rod to slide inside the thread groove, the extrusion force generated by the insertion rod sliding against the thread groove will drive the toothed cylinder 701 to rotate. When the toothed cylinder 701 rotates, it will drive the toothed shaft 702 to rotate. When the toothed shaft 702 rotates, it will drive the rubber shaft 703 to rotate. Since one end of the rubber shaft 703 far from the toothed shaft 702 is fixed to the bottom of the C-ring 601, when the rubber shaft 703 rotates, the rubber shaft 703 will change and become shorter by screwing. When the rubber shaft 703 becomes shorter, the change of the rubber shaft 703 becoming shorter by screwing will cause inward contraction on the surfaces of multiple arc-shaped elastic plates 402. When the rubber shaft 703 contracts, the contraction of the rubber shaft 703 will squeeze the middle parts of multiple arc-shaped elastic plates 402, causing the middle parts of the arc-shaped elastic plates 402 to contract inward and at the same time promoting the middle parts of the arc-shaped elastic plates 402 to gather towards the center. After that, the change of the rubber shaft 703 will also generate an upward pulling force on the arc-shaped elastic plates 402, making the arc-shaped elastic plates 402 wrap the rivet nut more evenly and powerfully, which can further correct the possible inclination of the rivet nut, evenly distribute the pressure when releasing the nut. At the same time, through the contraction and pulling action of the rubber shaft, when installing and aligning the window, it can reduce the situation that multiple arc-shaped elastic plates 402 are inclined when contacting the window surface due to the uneven structure of the window surface, and reduce the situation that the nut is inclined during installation with the window due to the inclination of the arc-shaped elastic plates 402 during window alignment installation, reducing nut installation problems caused by inclination or uneven pressure and improving the installation efficiency.
