[0023] like Figures 1 to 11 As shown, a car seat reverse package mechanism, the reverse package mechanism 58 is used to assist the back assembly to cover the back skin, realize the rapid covering of the back to maintain the balance of the production line, including a frame 59, the upper front side of the frame 59 is provided with a liftable installation positioning plate 60 for inverted installation of the back assembly, the back assembly is composed of a back seat sponge 57 and a back frame 48, and the back seat sponge 57 covers the back frame 48. A base 73 is provided at the lower front side of the frame 59, and a covering bracket for covering the back skin 56 is connected to the upper side of the base 73, and a clearance space is formed in the middle of the covering bracket for the back assembly to enter when it goes down, and a liftable headrest positioning block 72 is provided in the middle of the clearance space, the headrest positioning block 72 is at the lower end of the back assembly, and a pair of positioning pins are provided on the upper side of the headrest positioning block 72, which is used to position the headrest hole when the back skin is turned over. When in use, the chair back assembly is installed upside down on the lower side of the installation positioning plate 60, and the back skin is turned over and installed on the covering bracket. At this time, the outer surface of the back skin faces inward, and the headrest positioning block 72 holds up the headrest part of the chair back assembly. Then the installation positioning plate 60 drives the chair back assembly to descend into the middle of the covering bracket, and with the support of the covering bracket, the back skin is covered on the chair back assembly. The staff uses the compression gun 86 to fix the back skin 56 fixing tube strip to the chair back composite cotton 57 positioning frame line groove in sequence with the C-shaped nails in the gun.

[0024] In this embodiment, the covering bracket is composed of two groups of left and right support rod frames, the lower end of the right group of support rod frames is connected to the base 73, and a movable seat plate 78 that can move left and right relative to the base is provided on the upper left side of the base, and the lower end of the left group of support rod frames is connected to the movable seat plate 78, and the base is provided with a top cylinder A77 for driving the movable seat plate to move left and right, and the base is provided with a support seat 76 for installing the top cylinder A77, and the movable seat plate 78 is used for back skin support through the top cylinder A77; a horizontal bending section is provided at the upper end of the support rod frame, and a nylon roller is sleeved on the horizontal bending section.

[0025] In this embodiment, each set of support rod frames is composed of three support rod frames. Among the three support rod frames of each set of support rod frames, one is located at the front side, one is located at the rear side, and one is located at the side, showing a triangular distribution. The left set of support rod frames are the left support rod frame 79, the left rear support rod frame 80, and the left front support rod frame 81 respectively; the right set of support rod frames are the right front support rod frame 82, the right support rod frame 83, and the right rear support rod frame 84 respectively.

[0026] In this embodiment, on both sides below the installation positioning plate 60, there are backing plates. On the side of the backing plates facing the middle, there are profiling positioning blocks, namely the left profiling positioning block 70 and the right profiling positioning block 71 respectively. Through holes are provided on the backing plates, and positioning pins driven by cylinder B on the outer side of the backing plates to expand and contract are respectively the left cylinder B66 and the right cylinder B67. The profiling positioning blocks are adapted to the edge contour of the lower connecting plate of the regulator, and the entire backrest assembly is positioned by inserting the positioning pins into the built-in hole positions of the lower connecting plate.

[0027] In this embodiment, one end of the installation positioning plate 60 is further provided with a sensor 65, and the sensor 65 is used to control the start and stop of the cylinder 61 when sensing that the installation positioning plate 60 descends to a set position.

[0028] In this embodiment, a lifting cylinder 61 for driving the installation positioning plate 60 to lift and lower is installed on the top of the frame. A pair of upper guide columns are connected between the installation positioning plate 60 and the top of the frame, namely the left upper guide column 62 and the right upper guide column 63 respectively. The lower ends of the upper guide columns are fixedly connected to the upper side of the installation positioning plate 60. A linear bearing 64 cooperating with the upper guide columns is installed on the top of the frame; below the headrest positioning block 72, there is a multi-stage combined cylinder 85 for driving its lifting and lowering, enabling it to reach a multi-stage and emergency stop mode, which is convenient for operators to fix the back skin to the upper end of the backrest sponge with C-shaped nails, so as to reduce the operation mode of the operator driving nails and wrapping at the same time. A pair of lower guide columns are connected between the installation positioning plate 60 and the base, namely the left lower guide column 74 and the right lower guide column 75 respectively. The lower ends of the lower guide columns are fixedly connected to the base. Linear bearings cooperating with the lower guide columns are provided at both ends of the installation positioning plate 60, namely the left linear bearing 68 and the right linear bearing 69 respectively.

[0029] In this embodiment, a rod seat plate is fixedly connected to the lower end of the support rod frame. The rod seat plate is connected to the base or the movable seat plate by bolts. Installation holes are respectively arranged in an array on the base or the movable seat plate, and the position of each support rod frame can be adjusted according to needs, and fine adjustment can be performed on backrests of different models.

[0030] Take the backrest cotton padding 57 to wrap the backrest frame 48 to form a backrest assembly. Take the back skin 56 and put it on the wrapping bracket of the reverse wrapping mechanism 58. The positioning pins of the pillow positioning block 74 protrude upward and are shaped through the wrapping bracket. Actuate the top cylinder A77 to move the movable seat plate 78 horizontally to the left, so that the left support rod frame 79, the left rear support rod frame 80, and the left front support rod frame 81 above it expand outward synchronously to fully stretch the back skin 56 to ensure the wrapping effect. Invert and fix the backrest assembly under the installation positioning plate 60. Actuate the left top cylinder B66 and the right top cylinder 67 to eject the positioning pins to clamp the inner hole positions of the regulator lower connecting plate of the backrest frame 48 in the backrest cotton padding 57. Actuate the lifting cylinder 61 to lower the installation positioning plate 60, and the backrest assembly presses down to wrap the back skin 56. The pillow positioning block 74 descends synchronously. Through the segmented pressing of the lifting cylinder 61, every time a certain height is pressed down, the operator uses a compression gun 89 to sequentially fix the C-shaped nails in the gun to fix the back skin 56 to the backrest cotton padding 57 until the back skin completely wraps the backrest cotton padding 57. Then the operator removes the wrapped backrest assembly.

[0031] The reverse wrapping mechanism of this vehicle seat imitates manual operation. After the back skin is shaped, the lifting cylinder is used to assist in the segmented downward pressing of the backrest assembly, so that the back skin is reversely wrapped on the backrest cotton padding of the backrest assembly, achieving the most convenient method, which is conducive to the operator to fix the back skin on the backrest cotton padding, thus making up for the long working hours of back skin wrapping and increasing the problem of investment in handling and turnover trolleys.
