Technical Field
[0001] The utility model relates to the field of automobile seat slide rail assembly, in particular to an assembly device used for automobile seat slide rail assembly. Background Art
[0002] Figure 1 It is a schematic diagram of slide rail assembly in the prior art. Figure 2 It is a schematic diagram of the assembly of the male rail stop point and the retaining frame in the prior art. Figure 3 It is a schematic diagram of the principle of the slide rail assembly equipment in the prior art. Figure 4 It is a schematic diagram of the installation of the push head in the prior art. Figure 5 The figure is a schematic diagram of the contact between the male rail stop point and the retaining frame in the slide rail assembly equipment of the prior art.
[0003] like Figures 1 to 5 As shown, in the prior art, the car seat slide rail is composed of a male rail 100, a female rail 200, a retainer 300 and accessory parts. Usually, the male rail 100, the female rail 200 and the retainer 300 need to be assembled at an assembly station of a slide rail assembly line. The retainer supports the male rail in the slide rail, ensuring that there is enough clearance between the male rail and the female rail, and that the steel ball runs normally in the rail.
[0004] The integrity of the cage is critical. The current assembly method of the push head has a small cage stress area, and the stress-bearing part of the cage end is under great pressure, which is easy to be damaged and leads to customer complaints.
[0005] The assembly process of the car seat in the prior art is:
[0006] First, the pallet mother rail is assembled in place. Then, the male rail 100 is placed in the material channel and clamped by the material channel. Then, the male rail 100 is pushed into the mother rail 200 by the servo-driven push head. Then, the male rail stop point hooks the upper and lower layer retaining frames 300 and moves into the mother rail 200 until the male rail 100 completely enters the mother rail 200. Finally, the servo-driven push head mechanism 400 retreats to its original position.
[0007] The male rail 100 and the retaining frame 300 are placed in the material channel and clamped, the female rail is positioned on the tray 500, and the push head mechanism 400 is installed on the servo drive mechanism. For example, the push head mechanism 400 is installed on the mounting seat 420 through the push head 410, and then the mounting seat 420 is installed on the servo drive mechanism. The servo drive mechanism moves forward, the push head mechanism 400 pushes the male rail 100, and the male rail stop point 110 hooks the retaining frame 300 to move toward the female rail 200 until the male rail 100 and the retaining frame 300 completely enter the female rail 200.
[0008] However, the male rail stop point 110 is controlled by raw materials and has a size standard. The retainer 300 and the male rail 100 are placed in a dedicated material channel, and the male rail 100 is pressed on the retainer 300. When the male rail 100 moves forward, the retainer 300 also moves forward under the action of rolling friction, and the speed is 1 / 2 of the speed of the male rail 100. Finally, the rear end stop point of the male rail 100 will hook the retainer 300 and move into the female rail 200 (the female rail 200, the male rail 100, and the retainer 300 have an interference fit, and the retainer 300 will encounter greater resistance when entering).

[0058] Figure 6 The utility model is a structural schematic diagram of an assembly device for assembling a car seat slide rail. Figure 7 The utility model is a schematic diagram of the principle of the assembly device used for assembling the slide rail of the automobile seat. Figure 8 for Figure 7 Enlarged view of part A.
[0059] Fig. 9 The utility model is a structural schematic diagram of a push head mechanism in an assembly device for assembling a car seat slide rail. Fig.10 The utility model is a schematic diagram of the contact position between the push head mechanism and the end of the retaining frame in the assembly device for assembling the slide rail of the automobile seat.
[0060] like Figures 6 to 10 As shown, an assembly device for assembling a car seat slide rail includes a frame 10, a mother rail 20, a male rail 30, a retaining frame 40, a push claw mechanism 50 and a driving mechanism 60. The mother rail 20 is arranged at one end of the frame 10, and the male rail 30 is placed in the material channel 80 of the frame 10. The driving mechanism 60 is arranged at the other end of the frame 10, and the push claw mechanism 50 is installed on the driving mechanism 60. The driving mechanism 60 drives the push claw mechanism 50 to advance, so that the push claw mechanism 50 pushes the male rail 30 and the retaining frame 40 into the mother rail 20 together. The driving mechanism 60 here is preferably a servo driving mechanism.
[0061] Preferably, the pushing claw mechanism 50 includes a pushing head connecting rod 51 and a pushing claw 52 , the pushing claw 52 is installed on a first end of the pushing head connecting rod 51 , and a second end of the pushing head connecting rod 51 is connected to the driving mechanism 60 .
[0062] Further, the first end of the push head connecting rod 51 is a wedge-shaped connecting end, and the wedge-shaped connecting end is connected to the upper end of the push claw 52. The lower end of the push claw 52 can preferably be a hook.
[0063] The push head connecting rod 51 is installed at the lower part of the driving mechanism 60 , and the push claw 52 is located on the frame 10 .
[0064] Preferably, the retainer 40 includes an upper retainer 41 and a lower retainer 42 , and both sides of the male rail 30 are mounted in the upper retainer 41 and the lower retainer 42 , and the push claw 52 is located at the bottom of the male rail 30 .
[0065] In particular, a male rail stop point 31 is provided at the end of the male rail 30 , and the push claw 52 is abutted against the male rail stop point 31 to push the male rail 30 and the retaining frame 40 to be assembled into the female rail 20 .
[0066] In this embodiment, the male rail 30, the retaining frame 40 and the female rail 20 are interference fit. The shape of the male rail 30 matches the shape of the retaining frame 40.
[0067] The utility model is used for assembling the slide rail of the automobile seat. A novel push head structure is designed. When the mother rail tray 70 is in place, the male rail 30 is placed on the material channel, the material channel is clamped, and the driving mechanism 60 drives the push claw mechanism 50 to move forward.
[0068] When the upper end of the push claw 52 of the push claw mechanism 50 contacts the male rail 30, the push claw 52 pushes the male rail 30 forward. When the male rail stop point 31 contacts the retainer 40, the push claw 52 just pushes the retainer 40, and the retainer 40 works together with the push claw 52 at the male rail stop point 31 to push the retainer 40 into the female rail 20, thereby increasing the force bearing area of the retainer and reducing the risk of damage to the retainer.
[0069] The assembly process of the assembly device for assembling the slide rails of automobile seats is as follows: first, the pallet mother rail is in place and the male rail is placed on the material channel. Then, the material channel is clamped. Then, the driving mechanism drives the push claw mechanism to push the male rail forward. When the male rail stop point contacts the retaining frame, the push claw mechanism contacts the retaining frame at the same time. After the male rail stop point and the push claw simultaneously push the retaining frame into the mother rail, the driving mechanism retreats to its original position.
[0070] like Figure 8 As shown, the push claw 52 pushes the male rail 30, and the push claw 52 simultaneously pushes the retaining frame 40 to move forward until it completely enters the female rail.
[0071] In the prior art, the cage enters the mother rail completely by hooking at the male rail stop point. The resistance of the cage entering the mother rail (about 500N) is all borne by the stop point and the end of the cage. Due to the small contact area, the end of the cage will be easily broken due to excessive pressure.
[0072] However, the assembly device for assembling the automobile seat slide rails of the utility model adopts a push claw mechanism. The push claw of the new push head mechanism and the male rail stop point push the retaining frame at the same time, so that the force area of the retaining frame is increased, the pressure is reduced, and the end damage and breakage are avoided.
[0073] The assembly device for assembling automobile seat slide rails has a method of changing the original male rail stop point directly pushing the retaining frame into the female rail to a push claw and the male rail stop point jointly pushing the retaining frame into the female rail during the process of installing the male rail and the retaining frame into the female rail, thereby increasing the force-bearing area of the retaining frame and reducing the risk of damage to the retaining frame during the assembly process.
[0074] In summary, the utility model is used for assembling the automobile seat slide rail assembly device, which adopts a new structure of the push claw mechanism, and pushes the retaining frame simultaneously with the male rail stop point, so that the force area of the retaining frame is increased, the pressure is reduced, and the end is prevented from being damaged or broken.
[0075] The use of the assembly device can effectively increase the end force bearing area of the retaining frame, thereby avoiding the retaining frame from being broken due to the concentrated force on the end.
