Description

Technical Field

[0001] This invention belongs to the field of automotive parts assembly technology, specifically an automatic assembly device for seat slide rail locking mechanism bushings and springs. Background Technology

[0002] Cars are one of the most frequently used means of transportation in daily life. A car is assembled from a number of parts, among which the seats are installed inside the car. During installation, slide rails are pre-installed on the floor inside the car. After the slide rails are installed, the seats are installed on the slide rails. The slide rails allow the seats to move forward and backward, making it convenient for passengers to adjust the position of the seats according to their own needs. After adjustment, in order to prevent the seats from shifting due to inertia during driving and causing safety problems, a locking mechanism is installed at the slide rail position to limit the movement.

[0003] Under normal conditions, the compression spring pushes the locking pin vertically downward along the guide sleeve, causing the head of the locking pin to engage with the corresponding locking groove in the lower slide rail locking plate. At the same time, the torsion spring is pre-tensioned to keep the connecting rod arm in contact with the locking pin. The seat is rigidly fixed to the locking mechanism via the upper slide rail. When the user pulls the unlocking handle, the pulling force is transmitted to the connecting rod arm through the adjusting rod. The arm rotates around the pivot and pushes the locking pin upward, overcoming the pre-tension of the compression spring and disengaging it from the locking groove. At this time, the seat can be pushed to move the upper slide rail back and forth along the lower slide rail track. After the unlocking handle is released, the torsion spring releases its stored energy, causing the connecting rod arm to reset. The compression spring then pushes the locking pin precisely downward along the guide sleeve, re-engaging it with the locking groove in its current position. The entire mechanism returns to the locked state. The fixing bolts and anti-loosening washers ensure reliable connection of all parts, preventing loosening or abnormal noise caused by vehicle vibration.

[0004] Currently, the assembly of the bushing and spring inside the locking mechanism is done manually. During the assembly process, workers need to insert the plastic bushing into the inside of the spring. However, it is easy to miss some parts during the assembly process, which will cause some springs to fail to be assembled properly, affecting the efficiency of subsequent assembly. In addition, the shape of the spring is relatively special. After the two ends of the spring are assembled with the plastic bushing, they need to maintain a specific angle to facilitate subsequent assembly.

[0005] Therefore, the present invention provides an automatic assembly device for the seat slide rail locking mechanism bushing and spring. Summary of the Invention

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 13 As shown in the figure, an automatic assembly equipment for a seat slide rail locking mechanism bushing and spring according to an embodiment of the present invention includes a table 1, a turntable 2 is installed on one side of the top of the table 1, a clamp 21 is installed at the end of the turntable 2, a spring feeding rail 11 is installed on the other side of the top of the table 1, a bushing feeding rail 12 is provided on one side of the spring feeding rail 11, a nesting assembly is provided between the spring feeding rail 11 and the bushing feeding rail 12, a dispensing assembly is provided between the nesting assembly and the turntable 2, and a feeding assembly is provided above the nesting assembly; A support frame 13 is provided on the outer side of the bushing feeding track 12. The bottom end of the support frame 13 is installed on the top of the platform 1. A connecting block 131 is installed on the top of the support frame 13. A guide frame 132 is fixed on one side of the connecting block 131. A camera 4 is provided below the connecting block 131. An electric telescopic rod 41 is provided below the guide frame 132. A lifting block 411 is fixed at the bottom of the electric telescopic rod 41. A pair of clamps 412 are slidably connected to the bottom of the lifting block 411. A rotating plate 45 is rotatably connected to one side of the clamps 412. Among them, the camera 4 detects whether the head of the bushing is facing correctly, and drives the clamping plate 412 to clamp the bushing and correct it through the electric telescopic rod 41. When assembling the bushing and spring, the bushing needs to be inserted into the spring. During assembly, an external feeding device feeds the spring to the top of the spring feeding track 11. The bottom of the spring feeding track 11 integrates a vibration mechanism. The vibration of the vibration mechanism causes the spring inside the spring feeding track 11 to move uniformly towards the turntable 2. At the same time, the external feeding device feeds the bushing to the top of the bushing feeding track 12. The bottom of the bushing feeding track 12 also integrates a vibration mechanism. The vibration mechanism drives the bushing inside the bushing feeding track 12 to move towards the turntable 2. Sensors are installed at the discharge ends of both the spring feeding track 11 and the bushing feeding track 12. The sensors are used to detect whether the spring feeding track 11 and the bushing feeding track 12 are discharging material. When the sensor... After the spring feeding track 11 and the bushing feeding track 12 are detected to be discharging material, the feeding assembly is started. The feeding assembly can transport the bushing and spring to the position of the bushing assembly. The bushing assembly pushes the bushing into the inside of the spring. Then, the feeding assembly can transport the assembled bushing and spring into the inside of the fixture 21. After a set of bushings and springs are loaded into the fixture 21, the turntable 2 drives the next fixture 21 to rotate to a position close to the spring feeding track 11 and the bushing feeding track 12. Continuing to operate in this way can enable the bushing and spring to be assembled quickly, improve the assembly efficiency, and the spring feeding track 11 can limit the end direction of the spring, and the fixture 21 can guide the spring, thereby preventing the spring from changing direction during the assembly process and affecting the efficiency of subsequent assembly. When feeding the bushing at the top of the bushing feeding track 12, because the shapes of the two ends of the bushing are different, the shape of the bushing can be referenced. Figure 6The smaller diameter end needs to be moved forward. During the conveying process, the end may be oriented incorrectly. In this case, the bushing cannot be properly inserted into the spring. To prevent this problem, the bushing with the incorrect orientation needs to be corrected. Camera 4 takes pictures of multiple bushings passing through the bushing feeding track 12 and analyzes them simultaneously. When a single bushing is oriented incorrectly, the electric telescopic rod 41 is activated to push the lifting block 411. The lifting block 411 drives the clamping plate 412 to clamp the bushing, and the rotating plate 45 corrects the orientation of the bushing. When multiple bushings are oriented incorrectly, it indicates that the external feeding device has malfunctioned. At this time, the staff is alerted and the equipment operation is stopped, so that the bushing can be corrected in time and the operation of the equipment can be prevented from being affected by the failure of the feeding device.

[0024] like Figures 1 to 12 As shown, the lifting block 411 has a sliding groove inside, and a guide post is fixed inside the sliding groove. The top of the clamping plate 412 is slidably connected to the sliding groove of the lifting block 411, and the guide post passes through the inside of the clamping plate 412. Sliding rods 419 are fixed on both sides of the clamping plate 412. A guide plate 432 is slidably connected inside the sliding groove. A fourth channel 436 is opened on the upper part of the inner side of the guide plate 432, and a second channel 434 is opened on the lower part of the inner side of the guide plate 432. A first channel 433 is connected to one side of the fourth channel 436 and the second channel 434, and a third channel 435 is connected to the other side of the fourth channel 436 and the second channel 434. A storage groove 437 is opened at the top of the first channel 433, and the sliding rod 419 is slidably connected inside the storage groove 437. A protrusion 438 is fixed in the middle of the inner side of the guide plate 432. When the clamping plate 412 needs to clamp the bushing, the electric telescopic rod 41 pushes the lifting block 411 downward. When the clamping plate 412 is inserted into the groove of the bushing feeding track 12, the bottom end of the top frame 43 contacts the top end of the bushing feeding track 12. Under the reverse force of the bushing feeding track 12, the top frame 43 is pushed upward. The top frame 43 pulls the guide plate 432 upward. In the initial state, the sliding rod 419 is inside the receiving groove 437. At this time, the clamping plate 412 is at the outermost position of the bottom end of the lifting block 411. When the guide plate 432 moves upward, the sliding rod 419 slides into the first channel 433. During this process, the clamping plate 412 can continue to extend into the bushing for feeding. Inside the groove of track 12, slide rod 419 slides into the interior of second channel 434. During this process, guided by second channel 434, slide rod 419 can slide towards third channel 435. At this time, slide rod 419 can drive clamping plate 412 to clamp the bushing. Then, electric telescopic rod 41 drives lifting block 411 to rise. At this time, top frame 43 gradually rises. At the same time, third spring 431 pushes top frame 43 to reset. During this process, guide plate 432 is pushed down and reset by third spring 431. At the same time, slide rod 419 slides into third channel 435 and slides to the top of third channel 435. At this time, clamping plate 412 can clamp the bushing, realizing automatic clamping of bushing.

[0025] like Figures 1 to 12 As shown, a movable plate 441 is slidably connected inside the protrusion 438. A wedge block 44 is fixed to the top of the movable plate 441, and a fourth spring 442 is fixed to one side of the movable plate 441. One side of the fourth spring 442 is fixedly connected to the protrusion 438. When the slide bar 419 slides, the protrusion 438 can limit the slide bar 419. When the slide bar 419 slides from the inside of the third channel 435 to the top, the slide bar 419 will first push the side of the wedge block 44. At this time, the wedge block 44 drives the moving plate 441 to squeeze the fourth spring 442. When the slide bar 419 slides to the top of the third channel 435, the elastic force of the fourth spring 442 pushes the moving plate 441 to reset the wedge block 44. When the clamping plate 412 needs to lower the bushing, the electric telescopic rod 41 pushes the lifting block 411 to move downward. At this time, the top frame 43 will contact the top of the bushing feeding track 12 again and be pushed in the opposite direction. The top frame 43 drives the guide. As plate 432 moves upward, under the limiting and guiding action of wedge block 44, slide rod 419 slides from inside fourth channel 436 into inside first channel 433. At this time, the stroke of electric telescopic rod 41 is shortened, so that slide rod 419 only slides to the top of second channel 434. At this time, slide rod 419 drives clamping plate 412 away from bushing, and bushing can be lowered. Then, electric telescopic rod 41 drives lifting block 411 to rise, top frame 43 loses thrust, and third spring 431 spring force drives top frame 43 and guide plate 432 to slide upward, so that slide rod 419 can be reset to inside storage slot 437. At this time, clamping plate 412 can be automatically separated from bushing.

[0026] like Figures 1 to 14 As shown, a gear 454 is fixed to the end of the rotating shaft of the rotating plate 45, a support plate 133 is fixed to the bottom of the guide frame 132, and two sets of connecting plates 135 are fixed to the bottom of the support plate 133. A first toothed plate 136 is rotatably connected between each set of connecting plates 135, and one side of the first toothed plate 136 can mesh with the gear 454. After the clamping plate 412 clamps the bushing, the bushing needs to be turned around. The rotating plate 45 on the inner side of the clamping plate 412 will contact the bushing. After the electric telescopic rod 41 drives the lifting block 411 to rise, the electric telescopic rod 41 drives the lifting block 411 to move closer to the first toothed plate 136. Then the first toothed plate 136 meshes with the gear 454. The electric telescopic rod 41 pushes the lifting block 411 down to make the gear 454 roll 180° on the first toothed plate 136. At this time, the gear 454 can drive the rotating plate 45 to turn around, thereby adjusting the direction of the bushing.

[0027] like Figures 1 to 14 As shown, multiple steel balls 138 are slidably connected inside the connecting plate 135. A first spring 139 is fixed on one side of the steel ball 138. Multiple first positioning grooves 137 are opened on both sides of the first toothed plate 136. The steel ball 138 can engage with the first positioning groove 137. After the first toothed plate 136 drives the gear 454 to rotate, it will block the lifting block 411. Therefore, the first toothed plate 136 is set to be rotatably connected to the connecting plate 135. When the gear 454 meshes with the first toothed plate 136, the first spring 139 pushes the steel ball 138 into the first positioning groove 137. At this time, the elastic force of the first spring 139 can ensure that the first toothed plate 136 can drive the gear 454 to rotate. When the first toothed plate 136 passes the gear 454, it will contact the lifting block 411. At this time, the lifting block 411 pushes the first toothed plate 136. When the force on the first toothed plate 136 is greater than the sum of the first springs 139, the first positioning groove 137 will separate from the current steel ball 138. When the lifting block 411 passes from one side of the first toothed plate 136, the first positioning groove 137 will engage with the steel ball 138, thereby fixing the current first toothed plate 136. This allows the first toothed plate 136 to move downward without blocking the lifting block 411.

[0028] like Figures 1 to 14 As shown, the rotating plate 45 has two second positioning grooves 451 on the side near the clamping plate 412. An arc-shaped top block 452 is slidably connected to the side of the clamping plate 412 near the second positioning grooves 451. The arc-shaped top block 452 can engage with the second positioning grooves 451. A fifth spring 453 is fixed on one side of the arc-shaped top block 452. The fifth spring 453 is fixedly connected to the clamping plate 412. When the first toothed plate 136 drives the gear 454 to rotate, the total elastic force of the first spring 139 is greater than the total elastic force of the two fifth springs 453. At this time, the arc-shaped top block 452 can be squeezed into the interior of the clamping plate 412. When the first toothed plate 136 drives the gear 454 to rotate, the rotation angle may have a certain deviation. In order to prevent the deviation from affecting the correction effect, the arc-shaped top block 452 is set. When the rotating plate 45 is driven by the gear 454, the protrusion of the arc-shaped top block 452 will be inside the second positioning groove 451. If an angle deviation occurs, the fifth spring 453 pushes the arc-shaped top block 452 to make the second positioning groove 451 and the arc-shaped top block 452 automatically positioned through the arc surface, so that the gear 454 drives the rotating plate 45 to rotate. The deviation of a certain angle will be automatically corrected.

[0029] like Figures 1 to 10 As shown, a moving block 413 is fixed to the top of the electric telescopic rod 41. A two-way lead screw 414 is rotatably connected inside the guide frame 132. One end of the two-way lead screw 414 is connected to a gear ring 415 through a ratchet and ratchet structure. The two-way lead screw 414 is threadedly connected to the moving block 413. A lifting frame 416 is slidably connected inside the guide frame 132. A second spring 418 is fixed to the outside of the lifting frame 416. The top of the second spring 418 is fixedly connected to the guide frame 132. A second toothed plate 417 is fixed to the top of the lifting frame 416. The second toothed plate 417 is meshed with the gear ring 415. After the clamping plate 412 picks up the bushing, the electric telescopic rod 41 takes a certain amount of time to raise the bushing and correct its angle. During this time, the bushing feeding track 12 will continue to transport other bushings. Therefore, the gap created after picking it up will shift backward, so this distance needs to be automatically compensated. In the initial state, the electric telescopic rod 41 extends half its length. Then, the electric telescopic rod 41 extends downward, causing the clamping plate 412 to pick up the bushing and causing the lifting block 411 to automatically return to the half-length position. At this time, the top of the lifting block 411 contacts the lifting frame 416. Then, the electric telescopic rod 41 continues to drive the lifting block 411 to rise to the highest position. At this time, the lifting frame 416 drives the second toothed plate 417 to rise. The second toothed plate 417 and the toothed ring 41 5. Engagement: At this time, the gear ring 415 and the double-acting screw 414 are connected by a ratchet and tooth structure. The gear ring 415 drives the double-acting screw 414 to rotate, which causes the moving block 413 to move towards the support plate 133, thereby moving the electric telescopic rod 41. The electric telescopic rod 41 then moves the lifting block 411. At the same time, the gear 454 contacts the first toothed plate 136. Subsequently, the electric telescopic rod 41 drives the lifting block 411 to return to its original position. At this time, the second spring 418 drives the lifting frame 416 and the second toothed plate 417 to move downwards and return to their original positions. The second toothed plate 417 drives the gear ring 415 to rotate in the opposite direction. At this time, the gear ring 415 and the ratchet and tooth structure of the double-acting screw 414 are separated. After the clamping plate 412 puts the bushing back into the bushing feeding track 12 groove. The electric telescopic rod 41 drives the lifting block 411 to rise again and push the lifting frame 416. At this time, the second toothed plate 417 drives the toothed ring 415 to rotate again. The toothed ring 415 drives the bidirectional lead screw 414 to move the moving block 413 and drive the electric telescopic rod 41 to reset in a direction away from the support plate 133. This can realize the automatic movement of the electric telescopic rod 41 to compensate for the distance moved by the bushing feeding track 12 during the correction time.

[0030] like Figures 1 to 14 As shown, a second pull rope 424 is fixedly connected to one side of the moving block 413, a pull block 425 is fixed to the end of the rotating shaft of the first toothed plate 136, and the bottom end of the second pull rope 424 is fixedly connected to the pull block 425. After the first toothed plate 136 makes way for the lifting block 411, it needs to be reset for subsequent use. When the moving block 413 moves to the side of the support plate 133, the second pull rope 424 is relaxed. At this time, the first toothed plate 136 can rotate freely. When the moving block 413 is reset, it will pull the second pull rope 424 to tighten. The second pull rope 424 pulls the pull block 425 to tighten. At this time, the pull block 425 can drive the first toothed plate 136 to automatically reset through the rotating shaft. This can realize that the first toothed plate 136 can be automatically reset when the moving block 413 is reset.

[0031] like Figures 1 to 9As shown, a rotating plate 42 is fixed at the top of the camera 4, and a rotating groove 134 is opened at the bottom of the connecting block 131. The rotating plate 42 is rotatably connected inside the rotating groove 134. A winding wheel 421 is rotatably connected to the end of the rotating shaft of the rotating plate 42. A coil spring 422 is fixed outside the rotating shaft of the rotating plate 42. The other end of the coil spring 422 is fixedly connected to the winding wheel 421. A first pull rope 423 is wound inside the winding wheel 421. The other end of the first pull rope 423 is fixedly connected to the moving block 413. Among them, the rotating groove 134 limits the rotating plate 42, so that the maximum angle at which the rotating plate 42 can rotate toward the electric telescopic rod 41 is 30°. When the clamping plate 412 clamps the bushing to the position of the support plate 133, the first toothed plate 136 drives the gear 454 to adjust the direction of the bushing by the rotating plate 45. If the clamping plate 412 does not clamp the bushing tightly during the adjustment process, the bushing may fall off or slide. Therefore, when the moving block 413 moves, it will pull the first pull rope 423. The moving block 413 pulls the winding wheel 421 to rotate. The winding wheel 421 drives the rotating plate 42 to rotate through the coil spring 422. At this time, the rotating plate 42 drives the camera 4 to rotate 30° towards the support plate 133, so that the camera 4 can take another picture of the bushing after clamping. When the bushing in the picture is in an abnormal state, the operation of the electric telescopic rod 41 is stopped and the staff is notified to manually adjust the current bushing. When the moving block 413 is reset, the coil spring 422 drives the winding wheel 421 to automatically wind up the first pull rope 423, thereby realizing the secondary detection of the bushing and preventing the bushing from falling off or sliding during the correction process.

[0032] like Figures 1 to 6As shown, the nesting assembly includes a bushing pre-installation cylinder 15 mounted between the spring feeding rail 11 and the bushing feeding rail 12 via a mounting bracket. A guide block 151 is mounted on the top of the mounting bracket. The dispensing assembly includes a support platform 14 mounted on the top of the platform 1. A first moving mechanism 141 is mounted on the top of the support platform 14 near the bushing feeding rail 12. A second moving mechanism 142 is mounted on the top of the first moving mechanism 141. A first separating block 143 is mounted on the top of the second moving mechanism 142. A third moving mechanism 144 is mounted on the top of the support platform 14 near the spring feeding rail 11. The third moving mechanism 144... A second separating block 145 is installed on one side. The feeding assembly includes a mounting plate 3 set above the turntable 2. A first feeding mechanism 31 is installed on the side of the mounting plate 3 near the pre-installed cylinder 15 of the bushing. A second feeding mechanism 311 is installed on the side of the first feeding mechanism 31 away from the mounting plate 3. Two sets of third feeding mechanisms 32 are installed at the bottom of the second feeding mechanism 311. A stripping block 321 is installed at the bottom of one set of third feeding mechanisms 32, and a suction block 322 is installed at the bottom of the other set of third feeding mechanisms 32. One side of the suction block 322 is inserted into the interior of the stripping block 321. A permanent magnet 323 is installed inside the suction block 322. When the bushing is fed by the bushing feeding track 12, the bushing is fed into the groove at the top of the first separating block 143. At this time, the sensor detects the bushing and drives the second moving mechanism 142 to push the first separating block 143 to lift the bushing. The guide block 151 corrects the bushing. Then, the first moving mechanism 141 drives the second moving mechanism 142 and the first separating block 143 to move towards the bushing pre-installation cylinder 15, so that the first separating block 143 pushes the bushing to the end position of the bushing pre-installation cylinder 15. At the same time, the spring feeding track 11 feeds. When the sensor detects the spring, the spring is in the second separating block. Within slot 145, the third moving mechanism 144 drives the second separating block 145, which in turn moves the spring to the end of the bushing pre-assembly cylinder 15. Then, the pre-assembly pin extends from the end of the bushing pre-assembly cylinder 15, inserting first into the bushing and then into the spring. During this process, the first separating block 143 and the second separating block 145 provide limits for the bushing and spring, facilitating the insertion of the pre-assembly pin for assembly. Next, the bushing pre-assembly cylinder 15 retracts the pre-assembly pin to its initial position. Then, the second feeding mechanism 311 is activated, causing the lower multi-mechanism to descend as a whole. At this time, the stripping block 321 and the suction block 322... The spring assembled inside the second separating block 145 will be attracted by the permanent magnet 323. After attraction, the second feeding mechanism 311 will drive the entire structure to rise. After reaching the highest point, the first feeding mechanism 31 will drive the second feeding mechanism 311 and the entire structure below to move towards one side of the turntable 2. After moving to the position of the clamp 21, the second feeding mechanism 311 will drive the entire structure below to descend. After the second feeding mechanism 311 descends to the lowest position, the two sets of third feeding mechanisms 32 will drive the unloading block 321 and the suction block 322 to continue to descend. At this time, the suction block 322 can press the spring into the interior of the clamp 21. Then the suction block 322... The third feeding mechanism 32 drives the suction block 322 to rise, while the stripping block 321 remains stationary. When the suction block 322 drives the permanent magnet 323 to move upward to the highest point, the magnetic force of the permanent magnet 323 is insufficient to attract the spring, thus placing the assembled spring and bushing inside the fixture 21. Then, the third feeding mechanism 32 drives the stripping block 321 to reset, and the second feeding mechanism 311 drives the entire lower part to reset. The first feeding mechanism 31 drives the second feeding mechanism 311 and the entire lower part to reset, thus completing one assembly. This method can achieve automated assembly, reduce manual operation, and improve assembly efficiency.
