Description

Technical Field

[0001] This invention relates to an assembly device and assembly method for an automotive seat frame adjuster, belonging to the field of automotive parts manufacturing technology. Background Technology

[0002] In the field of automotive parts technology, consumers have higher requirements for the comfort and convenience of riding in a car, especially in cars with manual seat adjustment mechanisms. When manually adjusting the seat, the handwheel often feels loose and is accompanied by abnormal noise. The main reason for this is the uneven force applied to the handwheel during the rotation of the linkage rod. The linkage rod is usually used to unlock the adjusters on both sides. There is usually a gap between the linkage rod and the wall of the center hole of the adjuster. Therefore, the common practice is to fix the protrusion with a disc washer to avoid the slight gap causing shaking and abnormal noise. However, since the disc washer is fixed to the outside of the backrest, there is a risk of it loosening and falling off after repeated use. To solve this problem, the disc washer is now fixed by reversing the adjustment connecting plate. The disc washer is now fixed to the inside of the backrest instead of the outside. The outside of the backrest is fixed by flattening the head of the linkage rod. This operation effectively prevents loosening and falling off.

[0003] In the prior art, there is no operating device suitable for reversing the mounting plate of the seat adjuster to fix the disc-type washer. Therefore, in order to achieve the above functions, it is necessary to redesign an automotive seat frame seat adjuster assembly device. Summary of the Invention

A buffer spring is sleeved on the guide post between the angle adjuster positioning block and the fixed base plate.

[0010] Preferably, the pressing mechanism includes a lifting seat body, on which a circular positioning block is fixedly connected to facilitate pressing down into the top of the car seat frame; the bottom of the lifting seat body is fixedly connected to the top of the piston rod of the lifting top cylinder, the cylinder body of the lifting top cylinder is fixedly connected to a fixed plate at the bottom, and the fixed plate is then fixed to a fixed base plate at its bottom; a backrest sensor is provided on the front side of the fixed plate.

[0011] Preferably, the flattening mechanism includes a support frame fixedly connected to the top surface of the lifting seat, a vertical pneumatic slide is mounted on the support frame, an adapter block is fixedly connected to the slider of the vertical pneumatic slide, and a flattening pneumatic gripper is mounted on the adapter block.

[0012] Preferably, the clamping mechanism consists of a left clamping assembly and a right clamping assembly. Both the left and right clamping assemblies include a horizontal pneumatic slide mounted on a fixed shelf. A transition block is fixedly connected to the slider of the horizontal pneumatic slide, and a clamping pneumatic gripper is mounted on the transition block.

[0013] An assembly method for an automotive seat frame adjuster assembly device comprises the following steps: For the left car seat frame: S1. Place the lower angle adjuster connecting plate in the center of the positioning groove of the positioning disc, with the snap-fit ​​pin of the lower angle adjuster connecting plate facing upwards. S2. Next, align the inner adjusting device with the snap-fit ​​pin of the lower adjusting device connecting plate and insert it into the right seat frame adjusting device mounting groove. The two positioning holes of the inner adjusting device need to be fitted with two right positioning pins. After that, take the lower disc slide and insert it into the snap-fit ​​thread of the snap-fit ​​pin of the lower adjusting device connecting plate to pre-fix the lower adjusting device connecting plate and the inner adjusting device. S3. Take the left seat back frame of the left car seat frame and place it horizontally on the upper end of the inner angle adjuster. Its side plate is supported on the left concave-convex contour part of the left seat frame positioning block. The left concave-convex contour part is fitted with the concave-convex structure of the bottom surface of the side plate. S4. Place the outer angle adjuster on the top of the left seat back frame. The worker holds the left seat back frame and presses the lifting seat down so that its circular positioning block presses on the outer angle adjuster on the top of the left seat back frame. During the pressing process, the angle adjuster positioning block is cushioned by the vertical buffer component. S5. Take a square and hollow connecting rod. First, put the inner pad, the washer ring, and the upper disc slide into the top of the connecting rod in sequence. Then, insert the bottom of the connecting rod through the disc mounting hole on the outer angle adjuster and insert the bottom of the connecting rod into the square hole inside the lower angle adjuster connecting plate. At the same time, the telescopic rod of the electric cylinder should also extend upward and support the bottom of the connecting rod. S6. The horizontal pneumatic slide of the right clamping assembly feeds the front end of the clamping pneumatic gripper through the sheet metal opening of the left seat back frame to the side of the top of the linkage rod, and continues to move while the clamping pneumatic gripper controls the clamping of the linkage rod. S7. Install the disc between the connecting rod and the disc mounting hole of the outer angle adjuster, then install the upper angle adjuster connecting plate on the disc's round hole, and finally install the adjuster torsion mechanism on the top of the upper angle adjuster connecting plate. At this time, the top of the connecting rod extends upward from bottom to top through the square holes of the upper angle adjuster connecting plate and the adjuster torsion mechanism and is fitted with the outer gasket. S8. The flattening pneumatic gripper opens first, and then the whole thing is lowered by the vertical pneumatic slide table. The flattening pneumatic gripper pushes the outer pad downward, causing the adjuster torsion mechanism and the upper angle adjuster connecting plate to move downward. When the upper angle adjuster connecting plate moves downward, its locking pin moves downward at the same time. At this time, the upper disc slide cannot move downward under the restriction of the pad ring. Under the action of relative movement, the upper disc slide is locked into the locking thread root of the locking pin of the upper angle adjuster connecting plate. S9. Finally, the flattened pneumatic gripper closes, clamping the head of the connecting rod above the outer washer flat, so that the outer washer cannot come out. For the right-side car seat frame: S1. Place the lower angle adjuster connecting plate in the center of the positioning groove of the positioning disc, with the snap-fit ​​pin of the lower angle adjuster connecting plate facing upwards. S2. Next, align the inner adjuster with the snap-fit ​​pin of the lower adjuster connecting plate and insert it into the groove of the left seat frame adjuster. The two positioning holes of the inner adjuster need to be fitted with two left positioning pins. After that, take the lower disc slide and insert it into the snap-fit ​​thread of the snap-fit ​​pin of the lower adjuster connecting plate to pre-fix the lower adjuster connecting plate and the inner adjuster. S3. Take the right backrest of the right car seat frame and place it horizontally on the upper end of the inner angle adjuster. Its side plate is supported on the right concave-convex contour part of the right seat frame positioning block. The right concave-convex contour part is fitted with the concave-convex structure on the bottom surface of the side plate. S4. Place the outer angle adjuster on the top of the right seat back frame. The worker holds the right seat back frame and presses the lifting seat down so that its circular positioning block presses on the outer angle adjuster on the top of the right seat back frame. During the pressing process, the angle adjuster positioning block is cushioned by the vertical buffer component. S5. Take a square and hollow connecting rod. First, put the inner pad, the washer ring, and the upper disc slide into the top of the connecting rod in sequence. Then, insert the bottom of the connecting rod through the disc mounting hole on the outer angle adjuster and insert the bottom of the connecting rod into the square hole inside the lower angle adjuster connecting plate. At the same time, the telescopic rod of the electric cylinder should also extend upward and support the bottom of the connecting rod. S6. The horizontal pneumatic slide of the left clamping component sends the front end of the clamping pneumatic gripper through the sheet metal opening of the right seat back frame to the side of the top of the linkage rod, and continues to move while the clamping pneumatic gripper controls the clamping of the linkage rod. S7. Install the disc between the connecting rod and the disc mounting hole of the outer angle adjuster, then install the upper angle adjuster connecting plate on the disc's round hole, and finally install the adjuster torsion mechanism on the top of the upper angle adjuster connecting plate. At this time, the top of the connecting rod extends upward from bottom to top through the square holes of the upper angle adjuster connecting plate and the adjuster torsion mechanism and is fitted with the outer gasket. S8. The flattening pneumatic gripper opens first, and then the whole thing is lowered by the vertical pneumatic slide table. The flattening pneumatic gripper pushes the outer pad downward, causing the adjuster torsion mechanism and the upper angle adjuster connecting plate to move downward. When the upper angle adjuster connecting plate moves downward, its locking pin moves downward at the same time. At this time, the upper disc slide cannot move downward under the restriction of the pad ring. Under the action of relative movement, the upper disc slide is locked into the locking thread root of the locking pin of the upper angle adjuster connecting plate. S9. Finally, the flattened pneumatic gripper closes, clamping the head of the connecting rod above the outer washer flat, so that the outer washer cannot come out.

[0014] Preferably, in step S5, a limiting flange is provided at the top of the linkage rod to restrict the downward movement of the inner washer; the washer ring is C-shaped.

[0015] Compared with the prior art, the present invention has the following beneficial effects: the automobile seat frame adjuster assembly device can achieve: 1. For the inner corner adjuster: The inner corner adjuster assembly fixture can first place the lower corner adjuster connecting plate, then place the inner corner adjuster, and finally pre-fix the lower disc slide to the snap-fit ​​thread on the inner side of the lower corner adjuster connecting plate.

[0016] 2. For the outer angle adjuster: The flattening mechanism can descend and push the upper angle adjuster connecting plate downward, causing its locking thread to move down and create relative movement between it and the upper disc slide that cannot move down. The upper disc slide can then lock into the root of the locking thread. Finally, the flattening mechanism flattens the head of the connecting rod.

[0017] This device is suitable for reversing the angle adjuster connecting plate to fix the disc washer. It has a reasonable structural design and a stable and efficient working process.

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0035] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0036] like Figures 1-14 As shown, this embodiment provides an assembly device for an automotive seat frame adjuster, including a fixed base plate 1. An inner adjuster assembly fixture is provided on the fixed base plate. A pressing mechanism is provided above the inner adjuster assembly fixture. A liftable flattening mechanism is provided above the pressing mechanism. A clamping mechanism is provided on the side of the pressing mechanism to clamp the connecting rod between the inner and outer adjusters.

[0037] In this embodiment of the invention, the inner adjusting device assembly fixture includes an adjusting device positioning block 3 disposed above the fixed base plate and connected to the fixed base plate via a vertical buffer assembly 2. The upper surface of the adjusting device positioning block is symmetrically provided with a left seat frame adjusting device mounting contour groove 4 and a right seat frame adjusting device mounting contour groove 5. The left and right seat frame adjusting device mounting contour grooves are horizontally connected and a common positioning disc 6 is provided at the connected position. Two left positioning pins 7 are provided on the left seat frame adjuster mounting groove on the left side of the positioning disc, and two right positioning pins 8 are also provided on the right seat frame adjuster mounting groove on the right side of the positioning disc. The left seat frame positioning block 9 is provided on the lower left side of the left seat frame angle adjuster mounting groove, and the top surface of the left seat frame positioning block is provided with a left concave-convex contour part 10. The right seat frame positioning block 11 is provided on the lower right side of the right seat frame angle adjuster mounting groove, and the top surface of the right seat frame positioning block is provided with a right concave-convex contour part 12.

[0038] In this embodiment of the invention, the two left positioning pins and the two right positioning pins are symmetrical and are used to cooperate with the positioning holes on the angle adjuster. In this embodiment of the invention, the angle adjuster positioning block is fixedly connected to the left upper groove edge of the left seat frame angle adjuster mounting groove with a left stop block 13; the angle adjuster positioning block is fixedly connected to the right upper groove edge of the right seat frame angle adjuster mounting groove with a right stop block 14; the left and right stops can serve as edge stops when the inner angle adjuster is lowered.

[0039] A left sensor 17 is provided in the upper left area inside the contour groove of the left seat frame adjuster, and a right sensor 18 is provided in the upper right area inside the contour groove of the right seat frame adjuster.

[0040] The right sensor is used to prevent the inner and outer adjusters of the left seatback frame of the left car seat frame from being placed incorrectly. If the outer adjuster is placed on the inner side, because the outer contour of the outer adjuster is different from that of the inner adjuster, the outer adjuster will block the right sensor. If the right sensor is blocked, it means that the inner and outer adjusters are placed incorrectly. The principle of the left sensor is the same.

[0041] In this embodiment of the invention, a positioning groove 15 is provided on the top of the positioning disc, and a vertical clearance through hole 16 is provided at the bottom of the positioning groove. The inner diameter of the clearance through hole is smaller than the inner diameter of the positioning groove, and the clearance through hole extends downward through the positioning block of the angle adjuster. An electric cylinder 21 is fixedly connected to the bottom of the fixed base plate. The telescopic rod of the electric cylinder is vertically upward. A clearance opening is provided on the fixed base plate. The telescopic rod of the electric cylinder is coaxial with the clearance through hole and the clearance opening. A protective cover 22 is fixedly connected to the fixed base plate on the outer periphery of the electric cylinder.

[0042] In this embodiment of the invention, the vertical buffer assembly includes several vertical guide posts 19. The top ends of the guide posts are all fixedly connected to the angle adjuster positioning block, and the bottom ends of the guide posts pass through guide holes opened on the fixed base plate. Buffer springs 20 are sleeved on the guide posts between the angle adjuster positioning block and the fixed base plate.

[0043] In this embodiment of the invention, the pressing mechanism includes a lifting seat 23, on which a circular positioning block 24 is fixedly connected to facilitate pressing down into the top of the car seat frame; the bottom of the lifting seat is fixedly connected to the top of the piston rod of the lifting top cylinder 25, and the cylinder body of the lifting top cylinder is fixedly connected to the bottom fixed plate 48, which is then fixed to the bottom fixed base plate; a backrest sensor 50 is provided on the front side of the fixed plate, which will be detected when the left / right seat backrest is placed on the device to determine whether the device has a left / right seat backrest.

[0044] This inner seat adjuster assembly fixture features left and right seat frame adjusting grooves and positioning blocks on the adjusting block. The left seat frame positioning block and the right seat frame adjusting groove are designed for left-side car seat frames, while the right seat frame positioning block and the left seat frame adjusting groove are designed for right-side car seat frames. Furthermore, the left and right seat frame adjusting grooves share a common positioning disc, facilitating the installation of the adjusting plate and disc washer during adjusting assembly, resulting in a more compact fixture structure.

[0045] In this embodiment of the invention, the flattening mechanism includes a support frame 26 fixedly connected to the top surface of the lifting seat, a vertical pneumatic slide 27 mounted on the support frame, a transition block fixedly connected to the slider of the vertical pneumatic slide, and a flattening pneumatic gripper 28 mounted on the transition block.

[0046] In this embodiment of the invention, the clamping mechanism is composed of a left clamping component 29 and a right clamping component 30. Both the left and right clamping components include a horizontal pneumatic slide 31 mounted on a fixed shelf. A transition block is fixedly connected to the slider of the horizontal pneumatic slide, and a clamping pneumatic gripper 32 is mounted on the transition block.

[0047] The gripping fingers of the pneumatic gripper are fixed with rubber rods to prevent damage to the linkage rod.

[0048] An assembly method for an automotive seat frame adjuster assembly device comprises the following steps: For the left car seat frame (as shown in Figure 7-13): S1. Place the lower angle adjuster connecting plate 33 in the center of the positioning groove of the positioning disc, wherein the snap-fit ​​pin 49 of the lower angle adjuster connecting plate should face upward. S2. Next, align the inner adjusting device 34 with the snap-fit ​​pin of the lower adjusting device connecting plate and insert it into the right seat frame adjusting device mounting groove. The two positioning holes of the inner adjusting device need to be fitted with two right positioning pins. After that, take the lower disc slide 35 and snap it into the snap-fit ​​thread of the snap-fit ​​pin of the lower adjusting device connecting plate to pre-fix the lower adjusting device connecting plate and the inner adjusting device. S3. Take the left seat back frame 36 of the left car seat frame and place it horizontally on the upper end of the inner angle adjuster. Its side plate 37 is supported on the left concave and convex contour part of the left seat frame positioning block. The left concave and convex contour part is fitted with the concave and convex structure of the bottom surface of the side plate. S4. Place the outer angle adjuster 38 on the top of the left seat back frame. The staff holds the left seat back frame and the lifting body presses down so that its circular positioning block presses on the outer angle adjuster on the top of the left seat back frame. During the pressing process, the angle adjuster positioning block is cushioned by the vertical buffer component. S5. Take a square and hollow connecting rod 39. First, put the inner pad 40, the washer ring 41, and the upper disc slide into the top of the connecting rod in sequence. Then, insert the bottom of the connecting rod through the disc mounting hole 42 on the outer angle adjuster and insert the bottom of the connecting rod into the inner square hole 43 of the lower angle adjuster connecting plate. At the same time, the telescopic rod of the electric cylinder should also extend upward and support the bottom of the connecting rod. S6. The horizontal pneumatic slide of the right clamping assembly feeds the front end of the clamping pneumatic gripper through the sheet metal opening of the left seat back frame to the side of the top of the linkage rod, and continues to move while the clamping pneumatic gripper controls the clamping of the linkage rod. S7. Install the disc 44 between the connecting rod and the disc mounting hole of the outer angle adjuster, then install the upper angle adjuster connecting plate on the disc's round hole, and finally install the adjuster torsion mechanism 45 on the top of the upper angle adjuster connecting plate. At this time, the top of the connecting rod extends upward from bottom to top through the square holes of the upper angle adjuster connecting plate and the adjuster torsion mechanism and is fitted with the outer gasket 46. S8. The flattening pneumatic gripper opens first, and then the whole thing is lowered by the vertical pneumatic slide table. The flattening pneumatic gripper pushes the outer pad downward, causing the adjuster torsion mechanism and the upper angle adjuster connecting plate to move downward. When the upper angle adjuster connecting plate moves downward, its locking pin moves downward at the same time. At this time, the upper disc slide cannot move downward under the restriction of the pad ring. Under the action of relative movement, the upper disc slide is locked into the locking thread root of the locking pin of the upper angle adjuster connecting plate. S9. Finally, the flattened pneumatic gripper closes, clamping the connecting rod head 47 above the outer washer flat, so that the outer washer cannot come out. For the right-side car seat frame: S1. Place the lower angle adjuster connecting plate in the center of the positioning groove of the positioning disc, with the snap-fit ​​pin of the lower angle adjuster connecting plate facing upwards. S2. Next, align the inner adjuster with the snap-fit ​​pin of the lower adjuster connecting plate and insert it into the groove of the left seat frame adjuster. The two positioning holes of the inner adjuster need to be fitted with two left positioning pins. After that, take the lower disc slide and insert it into the snap-fit ​​thread of the snap-fit ​​pin of the lower adjuster connecting plate to pre-fix the lower adjuster connecting plate and the inner adjuster. S3. Take the right backrest of the right car seat frame and place it horizontally on the upper end of the inner angle adjuster. Its side plate is supported on the right concave-convex contour part of the right seat frame positioning block. The right concave-convex contour part is fitted with the concave-convex structure on the bottom surface of the side plate. S4. Place the outer angle adjuster on the top of the right seat back frame. The worker holds the right seat back frame and presses the lifting seat down so that its circular positioning block presses on the outer angle adjuster on the top of the right seat back frame. During the pressing process, the angle adjuster positioning block is cushioned by the vertical buffer component. S5. Take a square and hollow connecting rod. First, put the inner pad, the washer ring, and the upper disc slide into the top of the connecting rod in sequence. Then, insert the bottom of the connecting rod through the disc mounting hole on the outer angle adjuster and insert the bottom of the connecting rod into the square hole inside the lower angle adjuster connecting plate. At the same time, the telescopic rod of the electric cylinder should also extend upward and support the bottom of the connecting rod. S6. The horizontal pneumatic slide of the left clamping component sends the front end of the clamping pneumatic gripper through the sheet metal opening of the right seat back frame to the side of the top of the linkage rod, and continues to move while the clamping pneumatic gripper controls the clamping of the linkage rod. S7. Install the disc between the connecting rod and the disc mounting hole of the outer angle adjuster, then install the upper angle adjuster connecting plate on the disc's round hole, and finally install the adjuster torsion mechanism on the top of the upper angle adjuster connecting plate. At this time, the top of the connecting rod extends upward from bottom to top through the square holes of the upper angle adjuster connecting plate and the adjuster torsion mechanism and is fitted with the outer gasket. S8. The flattening pneumatic gripper opens first, and then the whole thing is lowered by the vertical pneumatic slide table. The flattening pneumatic gripper pushes the outer pad downward, causing the adjuster torsion mechanism and the upper angle adjuster connecting plate to move downward. When the upper angle adjuster connecting plate moves downward, its locking pin moves downward at the same time. At this time, the upper disc slide cannot move downward under the restriction of the pad ring. Under the action of relative movement, the upper disc slide is locked into the locking thread root of the locking pin of the upper angle adjuster connecting plate. S9. Finally, the flattened pneumatic gripper closes, clamping the head of the connecting rod above the outer washer flat, so that the outer washer cannot come out.

[0049] In this embodiment of the invention, in step S5, a limiting flange 51 is provided at the top of the linkage rod to restrict the downward movement of the inner washer; the washer ring is C-shaped.

[0050] In this embodiment of the invention, the fixed base plate is fixedly installed on a device frame 52, and the fixed base plate is also provided with a barcode printing station for printing product information barcodes on the left or right backrest frame after the angle adjuster is assembled, such as... Figure 14 As shown.

[0051] The barcode printing station is equipped with a left angle adjuster positioning block 53, a right angle adjuster positioning block 54, a dual proximity sensor 55, and a barcode printer 56.

[0052] The left and right angle adjuster positioning blocks are fixedly connected to the fixed base plate, and each of them is provided with a positioning groove for the two angle adjusters on the left or right seat back frame to be inserted and placed.

[0053] The dual proximity sensors are located on the rear side between the left and right adjuster positioning blocks to sense whether the left or right seat back frame is properly positioned on the left and right adjuster positioning blocks.

[0054] The barcode printer is located behind the dual proximity sensors. After the left or right seat back frame is in place, the barcode printer automatically prints the product information barcode 57, which is convenient for staff to affix to the left or right seat back frame.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
