Description

Technical Field

[0001] This application relates to the field of seat slide rail technology, and in particular to a seat slide rail assembly device. Background Technology

[0002] Seat rails are precision components installed between the seat base and the vehicle floor. They utilize internal ball bearings to enable smooth, effortless forward and backward movement of the seat, precisely adapting to different leg lengths and driving postures. Their robust locking mechanism ensures the seat remains firmly positioned while the vehicle is in motion, making them a key automotive interior component for ensuring driving safety, enhancing passenger comfort, and improving spatial flexibility.

[0003] Currently, the seat slide rail consists of an outer rail, an inner rail, and two retainers. When assembling the slide rail, the two retainers need to be manually installed into the inner rail first. Then, the inner rail and the outer rail are placed in the assembly equipment. The assembly equipment pushes the inner rail into the outer rail. After the assembly is completed, the staff takes out the assembled slide rail and puts the inner rail and the outer rail back in.

[0004] However, existing seat rail assembly methods suffer from significant efficiency bottlenecks. First, the manual installation of the cage is extremely time-consuming, requiring employees to repeatedly perform a series of delicate actions such as picking up, aligning, and pressing. Second, the loading and unloading processes are entirely manual. Each time a rail is assembled, a worker must manually remove it from the equipment, return to their station, and retrieve the new inner and outer rail components to reinsert it. This repetitive picking and placing of parts is not only labor-intensive but also forces the high-speed automated pressing equipment to frequently wait for manual intervention, significantly reducing the equipment's effective operating time. Utility Model Content

[0005] To improve the assembly efficiency of seat slide rails, this application provides a seat slide rail assembly device.

[0006] The seat slide rail assembly equipment provided in this application adopts the following technical solution: A seat slide rail assembly device includes a housing, a transfer mechanism disposed within the housing for moving multiple sets of inner and outer rails; an installation mechanism disposed within the housing for moving the inner rails; a gripping mechanism disposed within the housing for gripping the inner rails from the transfer mechanism and placing them into the installation mechanism; a first assembly mechanism disposed within the housing for assembling a retainer and the inner rails; a conveyor belt disposed within the housing for conveying the retainer; a robotic arm disposed within the housing, the moving end of the robotic arm being provided with a first gripper; the robotic arm driving the first gripper to grip the retainer and place it into the first assembly mechanism; the first assembly mechanism assembling the retainer into the inner rail of the installation mechanism; and a second assembly mechanism disposed within the housing for installing the inner rail with the retainer already assembled in the installation mechanism into the outer rail of the transfer mechanism.

[0007] By adopting the above technical solution, during the assembly of seat slide rails, the retainer is first placed in the conveyor belt, and the inner and outer rails are placed in the transfer mechanism. The transfer mechanism moves the inner and outer rails, and the gripping mechanism picks up the inner rail from the transfer mechanism and places it in the installation mechanism. The robotic arm drives the first gripper to pick up the retainer from the conveyor belt and place it in the first assembly mechanism. The first assembly mechanism assembles the retainer into the inner rail of the installation mechanism. Subsequently, the installation mechanism moves the inner rail, and the second assembly mechanism assembles the inner rail into the outer rail of the transfer mechanism, thus completing the automatic assembly of the seat slide rails. With this setup, the seat slide rail assembly equipment can automatically assemble the retainer and inner rails, and the assembly equipment can continuously assemble seat slide rails, thereby greatly improving the assembly efficiency of seat slide rails.

[0008] Preferably, the transfer mechanism includes a first guide rail, a plurality of transfer plates, a first transfer frame and a second transfer frame. The first guide rail is disposed inside the chassis, the plurality of transfer plates are slidably disposed on the first guide rail, the first transfer frame and the second transfer frame are disposed on the transfer plates, the inner rail is placed on the first transfer frame and the outer rail is placed on the second transfer frame.

[0009] By adopting the above technical solution, the workers place the inner rail and the outer rail on the first transfer frame and the second transfer frame respectively at the loading station. The transfer plate moves on the first guide rail, thereby driving the inner rail and the outer rail to move.

[0010] Preferably, the gripping mechanism includes a first gantry frame, a first translation plate, a lifting frame, and a second gripper. The first gantry frame is disposed inside the machine housing, the first translation plate is slidably disposed on the first gantry frame, the lifting frame is slidably disposed on the first translation plate, and the second gripper is slidably disposed on the lifting frame and used to grip the inner rail.

[0011] By adopting the above technical solution, the first translation plate and the lifting frame drive the second gripper to move up and down and move in parallel. At the same time, the second gripper can move horizontally on the lifting frame, realizing the free movement of the second gripper in three-dimensional space. This allows the second gripper to move and grab the inner rail in the transfer mechanism and then move the inner rail to place it in the installation mechanism.

[0012] Preferably, the mounting mechanism includes a second translation plate, a third translation plate, a drive assembly, and two clamping frames. The second translation plate is slidably disposed inside the chassis, the third translation plate is slidably disposed on the second translation plate, the two clamping frames are slidably disposed on the third translation plate, and the drive assembly is disposed on the third translation plate and is used to drive the two clamping frames to move toward each other or away from each other.

[0013] By adopting the above technical solution, when the gripping mechanism grips and transports the inner rail into the installation mechanism, the drive component drives the two clamping frames to move towards each other, and the two clamping frames clamp and fix the inner rail. Then, the second and third translation plates drive the inner rail to move through the clamping frames, which facilitates subsequent assembly work.

[0014] Preferably, the drive assembly includes a drive plate and four drive wheels. The drive plate is slidably mounted on a third translation plate, and the four drive wheels are symmetrically mounted on the drive plate. Two clamping plates are slidably mounted on the third translation plate, and two clamping frames are fixedly mounted on the two clamping plates. Each clamping plate has two inclined drive grooves, and the four drive wheels are slidably mounted in the four drive grooves respectively.

[0015] By adopting the above technical solution, the drive plate drives four drive wheels to move. The four drive wheels move in four drive slots. Since the drive slots are opened at an angle, the drive wheels can drive the two clamping plates to move towards each other or away from each other during the movement. The two clamping plates then drive the two clamping frames to move, thereby clamping and fixing the inner rail and releasing it.

[0016] Preferably, the first assembly mechanism includes a first conveying track, a conveying block, a second conveying track, a second gantry frame, a fourth translation plate, and multiple conveying grippers. The first and second conveying tracks are both located inside the chassis and connected end to end. A feed inlet is provided on the first conveying track, and the retainer is placed inside the first conveying track through the feed inlet. A conveying block is slidably arranged inside the chassis, and the conveying block pushes the retainer to move within the first conveying track. The second gantry frame is located inside the chassis, and the fourth translation plate is slidably arranged on the second gantry frame. Multiple conveying grippers are arranged on the fourth translation plate. Some of the conveying grippers drive the retainer to move from the first conveying track to the second conveying track, and some of the conveying grippers drive the retainer to move from the second conveying track to the installation mechanism.

[0017] By adopting the above technical solution, the robotic arm drives the first gripper to grab the cage and place it in the feed inlet. The cage falls from the feed inlet into the first conveying track. The conveying block moves and pushes the cage to the end of the first conveying track. The conveying gripper grabs the cage. The fourth translation plate then drives the conveying gripper to move. Part of the conveying gripper drives the cage in the first conveying track to the second conveying track, and another part of the conveying gripper drives the cage in the second conveying track to the installation mechanism, thereby enabling automatic assembly of the cage.

[0018] Preferably, the first conveying track is provided with a guide block at the feed inlet.

[0019] By adopting the above technical solution, the cage can be easily and accurately inserted into the feed inlet through the guide block.

[0020] Preferably, the second assembly mechanism includes a third gantry frame, a fifth translation plate, a sixth translation plate, a seventh translation plate, a first lifting plate, a movable gripper, and a fixed gripper. The third gantry frame is disposed inside the chassis. The fifth translation plate is slidably disposed on the third gantry frame. The sixth translation plate is slidably disposed on the fifth translation plate. The fixed gripper is fixedly disposed on the sixth translation plate. The seventh translation plate is slidably disposed on the sixth translation plate. The first lifting plate is slidably disposed on the seventh translation plate. The movable gripper is fixedly disposed on the first lifting plate.

[0021] By adopting the above technical solution, when the installation mechanism moves the inner rail to the second assembly mechanism, the seventh translation plate and the first lifting plate move the movable gripper. The movable gripper cooperates with the fixed gripper to clamp the inner rail. The fifth translation plate and the sixth translation plate move the inner rail to assemble it into the outer rail. Subsequently, the seventh translation plate and the first lifting plate move the movable gripper to contact the clamping of the inner rail. The fifth translation plate and the sixth translation plate move the movable gripper and the fixed gripper to reset, thereby facilitating the reassembly of the inner rail.

[0022] Preferably, a second lifting plate is slidably disposed on the sixth translation plate, two pressure rods are fixedly disposed on the second lifting plate, and a pressure block is slidably disposed on the second lifting plate.

[0023] By adopting the above technical solution, before assembling the inner rail, the second lifting plate drives the pressure block and two pressure rods to move downwards. The pressure rods and pressure block press down and fix the inner rail, making the inner rail more stable during the moving assembly process. At the same time, the position of the pressure block can be adjusted, thereby making the pressing and fixing effect of the inner rail better.

[0024] Preferably, the chassis is provided with a mounting base, and a limit plate is slidably mounted on the mounting base, the limit plate moving to abut against the outer rail.

[0025] By adopting the above technical solution, when the second assembly mechanism is used to assemble the inner rail, the limiting plate slides on the mounting base and moves to abut against the outer rail, thereby limiting the outer rail and facilitating the assembly of the slide rail.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When assembling seat slide rails, the retainer is first placed in the conveyor belt, and the inner and outer rails are placed in the transfer mechanism. The transfer mechanism moves the inner and outer rails, and the gripping mechanism picks up the inner rail from the transfer mechanism and places it in the installation mechanism. The robotic arm drives the first gripper to pick up the retainer from the conveyor belt and place it in the first assembly mechanism. The first assembly mechanism assembles the retainer into the inner rail of the installation mechanism. Subsequently, the installation mechanism moves the inner rail, and the second assembly mechanism assembles the inner rail into the outer rail of the transfer mechanism, thus completing the automatic assembly of the seat slide rails. With this setup, the seat slide rail assembly equipment can automatically assemble the retainer and inner rails, and the assembly equipment can continuously assemble seat slide rails, thereby greatly improving the assembly efficiency of seat slide rails. 2. With the help of the first assembly mechanism, the robotic arm drives the first gripper to grab the cage and place it in the feed inlet. The cage falls from the feed inlet into the first conveying track. The conveying block moves and pushes the cage to the end of the first conveying track. The conveying gripper grabs the cage. The fourth translation plate then drives the conveying gripper to move. Part of the conveying gripper drives the cage in the first conveying track to the second conveying track, and the other part of the conveying gripper drives the cage in the second conveying track to the installation mechanism, thereby enabling automatic assembly of the cage. 3. Through the second assembly mechanism, when the installation mechanism drives the inner rail to the second assembly mechanism, the seventh translation plate and the first lifting plate drive the moving jaw to move. The moving jaw cooperates with the fixed jaw to clamp the inner rail. The fifth translation plate and the sixth translation plate drive the inner rail to move and assemble it into the outer rail. Subsequently, the seventh translation plate and the first lifting plate drive the moving jaw to move and contact the clamping of the inner rail. The fifth translation plate and the sixth translation plate drive the moving jaw and the fixed jaw to move and reset, thereby facilitating the reassembly of the inner rail.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0030] This application discloses a seat slide rail assembly device.

[0031] Reference Figure 1 and Figure 2 A seat slide rail assembly device includes a housing 1, which houses a transfer mechanism 5, an installation mechanism 6, a gripping mechanism 7, a first assembly mechanism 8, a second assembly mechanism 9, a conveyor belt 2, and a robotic arm 3.

[0032] Reference Figure 3The transfer mechanism 5 includes two first guide rails 51, multiple transfer plates 52, a first transfer frame 53, and a second transfer frame 54. The two first guide rails 51 are fixedly installed inside the housing 1, with both ends of the first guide rails 51 extending out of the housing 1. The multiple transfer plates 52 are slidably mounted on the two first guide rails 51 and are driven to move by a drive structure. The first transfer frame 53 and the second transfer frame 54 are both fixedly mounted on the transfer plates 52. At the loading station 22, the operator places the inner rail 20 on the first transfer frame 53 and the outer rail 21 on the second transfer frame 54. The transfer plates 52 will then move the inner rail 20 and the outer rail 21 into the housing 1.

[0033] Reference Figure 4 The gripping mechanism 7 includes a first gantry frame 61, a first translation plate 62, a lifting frame 63, and a second gripper 64. The first gantry frame 61 is fixedly installed inside the housing 1. The first translation plate 62 is slidably mounted on the first gantry frame 61 in the horizontal direction via a guide rail slider. The drive source for the first translation plate 62 is a motor lead screw. The lifting frame 63 is slidably mounted on the first translation plate 62 in the vertical direction via a guide rail slider. The drive source for the lifting frame 63 is a cylinder. The second gripper 64 is slidably mounted on the bottom wall of the lifting frame 63 in the horizontal direction via a guide rail slider. The drive source for the second gripper 64 is a cylinder.

[0034] The first translation plate 62 and the lifting frame 63 work together to allow the second gripper 64 to move freely in three-dimensional space. After the first transfer frame 53 drives the inner rail 20 into the housing 1, the second gripper 64 moves to grab the inner rail 20 of the first transfer frame 53. Then, the second gripper 64 drives the inner rail 20 to move and place the inner rail 20 in the mounting mechanism 6.

[0035] Reference Figure 5 and Figure 6 The mounting mechanism 6 includes a second translation plate 71, a third translation plate 72, a drive assembly 73, and two clamping frames 74. The second translation plate 71 is slidably mounted horizontally within the housing 1 via a guide rail slider, and its drive source is a motor lead screw. The third translation plate 72 is slidably mounted horizontally on the second translation plate 71 via a guide rail slider, and its movement direction is perpendicular to that of the second translation plate 71. Its drive source is also a motor lead screw.

[0036] The drive assembly 73 is mounted on the third translation plate 72. The drive assembly 73 includes a drive plate 731 and four drive wheels 732. The drive plate 731 is slidably mounted on the third translation plate 72 in the horizontal direction via a guide rail slider. The four drive wheels 732 are symmetrically fixedly mounted on the drive plate 731.

[0037] Two clamping plates 10 are slidably mounted on the third translation plate 72 via guide rail sliders, and two clamping frames 74 are fixedly mounted on the two clamping plates 10. Each clamping plate 10 has two drive slots 11 spaced apart along its own length direction. Each drive slot 11 is inclined and parallel to each other, and four drive wheels 732 are slidably mounted in the four drive slots 11 of the two clamping plates 10.

[0038] The second gripper 64 grips the inner rail 20 between the two clamping frames 74. The drive plate 731 drives the four drive wheels 732 to move within the four drive slots 11. The inclined drive slots 11 allow the drive wheels 732 to move the two clamping plates 10 towards each other during their movement. The two clamping plates 10 then drive the two clamping frames 74 to clamp and fix the inner rail 20, thus placing the inner rail 20 within the mounting mechanism 6. Subsequently, the second translation plate 71 and the third translation plate 72 drive the inner rail 20 to move within the chassis 1, facilitating subsequent assembly.

[0039] Reference Figure 2 The retainer 19 is placed on the conveyor belt 2, which drives the retainer 19 to be transported toward the robotic arm 3. The moving end of the robotic arm 3 is fixedly equipped with a first gripper 4, which grabs the retainer 19 on the conveyor belt 2 and transports the retainer 19 into the first assembly mechanism 8.

[0040] Reference Figure 7 The first assembly mechanism 8 includes a first conveying track 81, a conveying block 82, a second conveying track 83, a second gantry frame 84, a fourth translation plate 85, and four conveying grippers 86. The first conveying track 81 and the second conveying track 83 are both fixedly installed inside the housing 1, and the two ends of the second conveying track 83 are respectively connected to the first conveying track 81 and the clamping frame 74.

[0041] Two feed ports 12 are provided on the top wall of the first conveying track 81 away from the second conveying track 83. Guide blocks 13 are fixedly installed at both ends and the middle of the feed ports 12 along the length of the first conveying track 81. The first gripper 4 places the retainer 19 in the guide block 13. The two retainers 19 enter the first conveying track 81 through the two feed ports 12.

[0042] The conveying block 82 is slidably installed in the housing 1 along the length of the first conveying track 81 by a cylinder and is located in the first conveying track 81. The cross-section of the conveying block 82 is T-shaped. The two ends of the top of the conveying block 82 in the horizontal direction abut against two retainers 19. When the conveying block 82 moves, it can drive the two retainers 19 to move to one end of the first conveying track 81 near the second conveying track 83.

[0043] The second gantry 84 is fixedly installed inside the housing 1. The fourth translation plate 85 is slidably installed on the second gantry 84 along the horizontal direction via a guide rail slider. Four conveying grippers 86 are fixedly installed on the fourth translation plate 85 at intervals along the horizontal direction. When the conveying grippers 86 open, two fingers of the conveying grippers 86 can abut against the two retainers 19. The fourth translation plate 85 drives the four conveying grippers 86 to move. Two of the conveying grippers 86 drive the two retainers 19 in the first conveying track 81 to the second conveying track 83, and the other two conveying grippers 86 drive the two retainers 19 in the second conveying track 83 to the clamping frame 74, thereby automatically completing the assembly of the retainers 19.

[0044] Reference Figure 3 The second assembly mechanism 9 includes a third gantry 91, a fifth translation plate 92, a sixth translation plate 93, a seventh translation plate 94, a first lifting plate 95, a moving gripper 96, and a fixed gripper 97. The third gantry 91 is fixedly installed inside the housing 1. The fifth translation plate 92 is slidably installed in the third gantry 91 along the horizontal direction via a guide rail slider. The drive source for the fifth translation plate 92 is a motor lead screw. The sixth translation plate 93 is slidably installed on the fifth translation plate 92 along the horizontal direction via a guide rail slider. The drive source for the sixth translation plate 93 is a cylinder.

[0045] A fixed gripper 97 is fixedly installed at one end of the sixth translation plate 93 in the horizontal direction, and a movable gripper 96 is movably installed at the other end of the sixth translation plate 93. A seventh translation plate 94 is slidably installed on the sixth translation plate 93 in the horizontal direction via a guide rail slider, and a first lifting plate 95 is slidably installed on the seventh translation plate 94 in the vertical direction via a guide rail slider. The driving source for both the seventh translation plate 94 and the first lifting plate 95 is a cylinder, and the movable gripper 96 is fixedly installed on the first lifting plate 95.

[0046] A second lifting plate 14 is slidably mounted vertically on the middle of the sixth translation plate 93 via a guide rail slider. The driving source for the second lifting plate 14 is a cylinder. Pressure rods 15 are fixedly mounted at both ends of the second lifting plate 14 in the horizontal direction. A pressure block 16 is slidably mounted on the middle of the second lifting plate 14 and is fixedly connected to the second lifting plate 14 by bolts.

[0047] The mounting mechanism 6 transports the inner rail 20 with the assembled retainer 19 to the second assembly mechanism 9. The seventh translation plate 94 and the first lifting plate 95 drive the moving gripper 96 to move. The moving gripper 96 cooperates with the fixed gripper 97 to clamp and fix the inner rail 20. Subsequently, the second lifting plate 14 drives the pressure rod 15 and the pressure block 16 to descend and move to press the inner rail 20, further improving the fixing effect of the inner rail 20.

[0048] A mounting base 17 is fixedly installed inside the chassis 1 on the side of the second transfer frame 54 away from the second assembly mechanism 9. A limiting plate 18 is slidably mounted on the mounting base 17 in the horizontal direction via a guide rail slider. The driving source of the limiting plate 18 is a cylinder. The transfer plate 52 drives the outer rail 21 to move through the second transfer frame 54, so that the outer rail 21 is aligned with the inner rail 20 in the second assembly mechanism 9. The limiting plate 18 moves to abut against the end of the outer rail 21 and limits the movement of the outer rail 21.

[0049] Subsequently, the fifth translation plate 92 and the sixth translation plate 93 move the inner rail 20, allowing it to be assembled into the outer rail 21. After the seat slide rail is assembled, the transfer plate 52 moves the seat slide rail out of the machine housing 1, and the worker removes the seat slide rail at the unloading station 23.

[0050] The implementation principle of a seat slide rail assembly device according to an embodiment of this application is as follows: At the loading station 22, the operator places the inner rail 20 on the first transfer frame 53 and the outer rail 21 on the second transfer frame 54. The transfer plate 52 moves the inner rail 20 and outer rail 21 into the housing 1. The second gripper 64 moves to grip the inner rail 20 on the first transfer frame 53, and then moves the inner rail 20 between two clamping frames 74. The drive plate 731 drives four drive wheels 732 to move within four drive slots 11. The inclined drive slots 11 allow the drive wheels 732 to move the two clamping plates 10 towards each other during movement. The two clamping plates 10 then drive the two clamping frames 74 to clamp and fix the inner rail 20, thus placing the inner rail 20 within the mounting mechanism 6. Subsequently, the second translation plate 71 and the third translation plate 72 move the inner rail 20 within the housing 1, facilitating subsequent assembly.

[0051] The robotic arm 3 uses the first gripper 4 to pick up the retainers 19 from the conveyor belt 2 and place them in the first conveyor track 81. The conveyor block 82 moves two retainers 19 to one end of the first conveyor track 81 near the second conveyor track 83. The fourth translation plate 85 moves four conveyor grippers 86. Two of the conveyor grippers 86 move two retainers 19 from the first conveyor track 81 to the second conveyor track 83, and the other two conveyor grippers 86 move two retainers 19 from the second conveyor track 83 to the clamping frame 74, thus automatically completing the assembly of the retainers 19.

[0052] The mounting mechanism 6 transports the inner rail 20, already assembled with the retainer 19, to the second assembly mechanism 9. The seventh translation plate 94 and the first lifting plate 95 move the moving gripper 96, which cooperates with the fixed gripper 97 to clamp and fix the inner rail 20. Subsequently, the second lifting plate 14 moves the pressure rod 15 and the pressure block 16 downward to press the inner rail 20, further improving the fixing effect of the inner rail 20. The transfer plate 52 moves the outer rail 21 through the second transfer frame 54, aligning the outer rail 21 with the inner rail 20 in the second assembly mechanism 9. The limiting plate 18 moves to abut the end of the outer rail 21 and limits its position. Then, the fifth translation plate 92 and the sixth translation plate 93 move the inner rail 20, assembling it into the outer rail 21. After the seat slide rail is assembled, the transfer plate 52 moves the seat slide rail out of the housing 1, and the worker removes the seat slide rail at the unloading station 23. The seat slide rail assembly equipment can automatically assemble the retainer 19 and the inner rail 20. At the same time, the assembly equipment can continuously assemble the seat slide rail, thereby greatly improving the assembly efficiency of the seat slide rail.
