[0001] This invention relates to the field of automotive seat equipment technology, specifically to an automatic assembly and nailing fixture for automotive seats. Background Technology

[0002] This automated assembly and nailing fixture is an automated fastening device for automotive seat components (seats and mounting brackets). Through the coordinated operation of robots, feeding components, and nailing components, it achieves efficient and precise assembly of seats and mounting brackets, and is suitable for batch assembly scenarios in automotive seat production lines.

[0003] Traditional assembly methods require manual or semi-automatic equipment to tighten screws at multiple connection points between the seat and the mounting frame. Since the screws need to be aligned and screwed in one by one, the operation is not only cumbersome, but also time-consuming for a single seat. In addition, the tool position needs to be adjusted repeatedly during the screwing process, which is difficult to meet the high-efficiency screwing requirements of the production line. Furthermore, if the seat needs to be maintained or replaced in the future, the screws need to be removed one by one, which is inefficient and increases after-sales maintenance costs.

The sliding plates 503 are slidably connected to the outer wall of the sliding groove 202. The purpose of this setup is that when the feeding assembly 5 is started, the motor 501 drives one of the rotating shafts 505 to rotate. Through the transmission of the synchronous pulley 504 and the synchronous belt 502, the sliding plate 503 fixed on the synchronous belt 502 slides along the sliding groove 202 of the feeding frame 2. The sliding plate 503 pushes the mounting frame 6 to move on the upper surface of the feeding frame 2, and transports the mounting frame 6 to the assembly position corresponding to the seat 3. A parking platform 201 is fixedly connected to the outer wall of the feeding rack 2. The parking platform 201 is used to park the assembled seat 3. The purpose of this setup is that after assembly, the feeding assembly 5 continues to drive the mounting frame 6 to move, transporting the assembled seat 3 to the parking platform 201 on the outer wall of the feeding frame 2, waiting to enter the next process. Robot 1 is set on the outside of feeding rack 2, mounting rack 6 is set on top of feeding rack 2, fork arm 101 is installed on the robotic arm of robot 1, and seat hole 301 is opened on the top of seat 3. Robot 1 is inserted into seat hole 301 through fork arm 101. The purpose of this setup is that the robot 1 uses the fork 101 on its robotic arm to insert into the seat hole 301 on the top of the seat 3, and moves the seat 3 from the storage area to the top of the feeding rack 2, ready to be assembled with the mounting bracket 6 on the top of the feeding rack 2. The nailing assembly 4 includes a sliding groove frame 401, an arc-shaped push rod 402, and a guide rail 403. The two guide rails 403 are fixedly connected to the outer wall of the feeding frame 2. The sliding groove frame 401 is slidably connected to the lower surface of the two guide rails 403. A slider is slidably connected between the sliding groove frame 401 and the guide rails 403. The arc-shaped push rod 402 is fixedly connected to the upper surface of the slider. Several arc-shaped material plates 405 are arranged between the two guide rails 403. The arc-shaped material plates 405 are fixedly connected to the outer wall of the feeding rack 2. The pins 8 are slidably connected to the inner wall of the arc-shaped material plates 405. One end of the arc-shaped material plate 405 is fixedly connected to the feeding pipe 404, which is inclined. The purpose of this design is to allow the sliding groove frame 401 to slide along the guide rail 403, thereby driving the arc-shaped push rod 402 on the slider to move.

[0019] Combination Figure 5 As shown, the pin 8 slides along the feed tube 404 and slides onto the arc-shaped material plate 405. Guided by the guide rail 403, the two arc-shaped push rods 402 first approach each other and merge together, and then push the pin 8 to pass through the limiting hole 602 of the mounting bracket 6 and the insertion hole 303 of the channel steel 302 in sequence.

[0020] The card holder 7 includes an arc-shaped card plate 701 and a circular spring 702. Several arc-shaped card plates 701 are fixedly connected to the inner wall of the channel steel 302, and there is a gap between the arc-shaped card plates 701. The arc-shaped card plates 701 are made of rubber, and the outer wall of the arc-shaped card plates 701 is arc-shaped. The circular spring 702 is sleeved on the outer wall of the arc-shaped card plates 701. An arc groove 7010 is provided on the inner wall of the arc-shaped card plates 701. A ball is provided at one end of the pin 8, and the arc groove 7010 and the ball are inserted and engaged. The purpose of this design is that after the pin 8 enters the channel steel 302, it slides through the arc plate 9, and the ball at its end contacts the card holder 7. The arc plate 701 of the card holder 7 is made of rubber and can be deformed. The outer wall is fitted with a circular spring 702. After the ball is embedded in the arc groove 7010 of the arc plate 701, the circular spring 702 tightens the arc plate 701, and the pin 8 is firmly fixed by the elastic clamping force, thus completing the assembly of the seat 3 and the mounting bracket 6, thereby achieving quick insertion and quick removal.

[0021] An arc-shaped plate 9 is fixedly connected to the inner wall of the channel steel 302. The arc-shaped plate 9 is used for the sliding transition of the insert pin 8 and to support the movement of the insert pin 8.

[0022] The drive assembly 10 includes a dual-axis motor 1001 and a fixed frame 1002. The fixed frame 1002 is fixedly connected to the inner side of the feeding frame 2. The dual-axis motor 1001 is mounted on the fixed frame 1002 and is located inside the synchronous belt 502. The two output shafts of the dual-axis motor 1001 are respectively connected to screws 1003. A fixed block 4010 is fixedly connected to the lower surface of the sliding groove frame 401. The screws 1003 pass through the fixed block 4010 and are threadedly connected. The purpose of this configuration is that when the dual-axis motor 1001 of the drive assembly 10 is started, its output shaft drives the screw 1003 to rotate. The screw 1003 is threadedly engaged with the fixing block 4010 under the sliding slot frame 401, which pushes the sliding slot frame 401 to slide along the guide rail 403.

[0023] The outer wall of the channel steel 302 is provided with a docking hole 304. The inner wall of the mounting bracket 6 is fixedly connected with a plug rod 11. The seat 3 docks with the plug rod 11 through the docking hole 304. The outer wall of the mounting bracket 6 is provided with a mounting hole 601, which is used to install and fix with the car with screws to achieve initial docking.

[0024] A thin rod 1101 is fixedly connected to the top of the insertion rod 11, and a conical umbrella 1102 is fixedly connected to the top of the thin rod 1101. The conical umbrella 1102 is a retractable structure. After the insertion rod 11 is inserted into the docking hole 304, the conical umbrella 1102 unfolds to limit the channel steel 302. The retractable structure of the conical umbrella 1102 at the top of the insertion rod 11 retracts when passing through the docking hole 304 and unfolds after passing through, thus limiting the channel steel 302 and preventing relative movement between the two. At the same time, the insertion hole 303 on the channel steel 302 is precisely aligned with the limiting hole 602 on the mounting bracket 6, preparing for subsequent nailing.

[0025] Working principle: Robot 1 uses the fork 101 on its robotic arm to insert into the seat hole 301 on the top of the seat 3, and moves the seat 3 from the storage area to the top of the feeding rack 2, ready to be assembled with the mounting bracket 6 on the top of the feeding rack 2.

[0026] When the feeding assembly 5 is started, the motor 501 drives one of the rotating shafts 505 to rotate. Through the transmission of the synchronous pulley 504 and the synchronous belt 502, the sliding plate 503 fixed on the synchronous belt 502 slides along the sliding groove 202 of the feeding frame 2. The sliding plate 503 pushes the mounting frame 6 to move on the upper surface of the feeding frame 2, and transports the mounting frame 6 to the assembly position corresponding to the seat 3.

[0027] A docking hole 304 is provided on the channel steel 302 at the bottom of the seat 3. The insertion rod 11 on the inner wall of the mounting bracket 6 is inserted into the docking hole 304 to achieve initial docking. At this time, the retractable structure of the conical umbrella 1102 at the top of the insertion rod 11 retracts when passing through the docking hole 304 and unfolds after passing through, thus limiting the channel steel 302 and preventing relative movement between the two. At the same time, the insertion hole 303 on the channel steel 302 is precisely aligned with the limiting hole 602 on the mounting bracket 6, preparing for subsequent nailing.

[0028] When the dual-axis motor 1001 of the drive assembly 10 is started, its output shaft drives the screw 1003 to rotate. The screw 1003 is threadedly engaged with the fixed block 4010 under the sliding groove frame 401, pushing the sliding groove frame 401 to slide along the guide rail 403, thereby driving the arc-shaped push rod 402 on the slider to move.

[0029] Combination Figure 5 As shown, the insert 8 slides along the feed tube 404 and onto the arc-shaped material plate 405. Guided by the guide rail 403, the two arc-shaped push rods 402 first approach and merge together, and then push the insert 8 through the limiting hole 602 of the mounting bracket 6 and the insertion hole 303 of the channel steel 302 in sequence. When the arc-shaped push rod 402 retracts, it pushes the insert 8 in the opposite direction. The insert 8 moves to the inside of the feed tube 404. When the arc-shaped push rod 402 moves away from the arc-shaped material plate 405, the insert 8 slides back towards the port of the limiting hole 602 under the action of the slope of the feed tube 404.

[0030] After the pin 8 enters the channel steel 302, it slides through the arc plate 9 and the ball at its end contacts the card holder 7. The arc plate 701 of the card holder 7 is made of rubber and can be deformed. The outer wall is fitted with a circular spring 702. After the ball is embedded in the arc groove 7010 of the arc plate 701, the circular spring 702 tightens the arc plate 701. The pin 8 is firmly fixed by the elastic clamping force, thus completing the assembly of the seat 3 and the mounting bracket 6, thereby achieving quick insertion and quick removal.

[0031] After assembly, the feeding assembly 5 continues to drive the mounting frame 6 to move, transporting the assembled seat 3 to the parking platform 201 on the outer wall of the feeding frame 2, waiting to enter the next process.
