[0037] In the embodiment, the shape of fabric spreading flat plate 310 is same as the shape of the coated fabric of automobile sun visor, the coated fabric of automobile sun visor is placed on fabric spreading flat plate 310, and the periphery is limited by limiting piece 320, when replacing the coated fabric, the used fabric quick change subassembly 300 can be taken down from lifting table 210 as a whole, and then the fabric quick change subassembly 300 filled with coated fabric is installed on lifting table 210, which can improve the replacement efficiency of coated fabric.

[0038] Optionally, fabric spreading flat plate 310 is provided with positioning protrusion 311, and positioning protrusion 311 is used for cooperating with the opening arranged on the coated fabric. The shape and position of positioning protrusion 311 are same as the opening arranged on the coated fabric, and when the coated fabric is placed on fabric spreading flat plate 310, positioning protrusion 311 can well position the coated fabric on fabric spreading flat plate 310 to prevent the fabric from being skewed or wrinkled.

[0039] Optionally, in order to facilitate the movement of fabric quick change subassembly 300, the two sides of fabric spreading flat plate 310 are provided with handle 312.

[0040] Lifting mechanism 220 is used for driving lifting table 210 to lift.

[0041] Specifically referring to Figure 2 And Figure 3The lifting platform assembly 200 further comprises a support plate 250 fixed vertically on the frame 100 and a sliding track 260 vertically arranged on the support plate 250, and the lifting platform 210 is slidingly installed on the sliding track 260.

[0042] The lifting mechanism 220 comprises a screw rod 221 vertically arranged and rotatably installed on the support plate 250, a driving motor 222 installed on the support plate 250 and in driving connection with the screw rod 221, and a nut seat 223 fixed on the lifting platform 210 and in threaded cooperation with the screw rod 221, and the lifting platform 210 can be lifted by controlling the driving motor 222 to drive the screw rod 221 to rotate.

[0043] It can be understood that, in addition to the driving structure of the screw rod and the nut, the lifting mechanism 220 can also adopt driving modes such as gear and rack, chain, belt, etc., which will not be described herein.

[0044] The first photoelectric sensor 230 is used to detect the position of the top surface of the coated fabric stacked on the placement area, and according to the detected top surface position, the lifting mechanism 220 is controlled to drive the lifting platform 210 to lift, so that the uppermost layer of coated fabric is always maintained at a set height.

[0045] The horizontal line of sight of the first photoelectric sensor 230 coincides with the top surface of the coated fabric, at this time, the front of the first photoelectric sensor 230 has a shielding signal, when the manipulator takes away the uppermost layer of coated fabric, the front of the first photoelectric sensor 230 has no shielding, at this time, the lifting mechanism 220 is controlled to drive the lifting platform 210 to rise until the first photoelectric sensor 230 detects the shielding signal again, and then stop, thereby ensuring that the uppermost layer of coated fabric is always maintained at a set height.

[0046] In some embodiments, the support plate 250 is vertically spaced apart along the side edges and has a plurality of U-shaped photoelectric sensors 270, and the lifting platform 210 is provided with a light shield 211 which can pass through each U-shaped photoelectric sensor 270 in turn during lifting. When the lifting platform 210 moves up and down, the light shield 211 passes through each U-shaped photoelectric sensor 270 in turn, and when the light shield 211 passes through the U-shaped photoelectric sensor 270, the corresponding U-shaped photoelectric sensor 270 will generate an induction signal, thereby monitoring the speed and general position of the lifting platform 210.

[0047] In some embodiments, the lower side of the lifting platform 210 is provided with a second photoelectric sensor 240 facing the upper side, and the lifting platform 210 and the emitting path of the second photoelectric sensor 240 on the fabric spreading flat plate 310 are hollowed out. When the lifting platform 210 still has coated fabric, the second photoelectric sensor 240 detects a shielding signal, and when the coated fabric is taken out, the second photoelectric sensor 240 detects no shielding, at this time, the emitting signal is sent to the receiving device to prompt the operator to supplement the coated fabric.

[0048] Referring to Figure 1 and Figure 5 The embodiment also includes a lifting limiting assembly 400, which includes a limiting frame 410 and a plurality of guide vertical rods 420 arranged on the upper side of the limiting frame 410.

[0049] The limiting frame 410 is arranged below the lifting platform 210 and fixed on the rack 100.

[0050] The upper end of each guide vertical rod 420 penetrates the lifting platform 210 and is in sliding guide connection therewith.

[0051] Specifically, the limiting frame 410 includes a bottom plate 411 fixed on the rack 100, a limiting plate 412 arranged above the bottom plate 411, and a support rod 413 supported between the bottom plate 411 and the limiting plate 412, and each vertical rod is fixed on the limiting plate 412.

[0052] The guide vertical rods 420 play a guiding and limiting role in the lifting of the lifting platform 210, and the limiting frame 410 plays a role in limiting the lowest position when the lifting platform 210 is lowered.

[0053] Preferably, the limiting frame 410 is provided with a third photoelectric sensor 430 for detecting the distance between the lifting platform 210 and the limiting frame 410, and the third photoelectric sensor 430 is provided with two, which are respectively located on the lower side of the limiting plate 412 and aligned upward to the hollows on the limiting plate 412. The light signal emitted by the third photoelectric sensor 430 can penetrate the limiting plate 412 and be directed to the lifting platform 210, so that the distance between the lifting platform 210 and the limiting plate 412 can be measured by the third photoelectric sensor 430, thereby determining the position of the lifting platform 210.

[0054] The application can automatically supply the fabric during the process of covering the sun visor. The covering fabric is stacked and placed on the placing area on the lifting platform 210, and the first photoelectric sensor 230 detects the position of the top surface of the covering fabric. When the first photoelectric sensor 230 detects that the mechanical hand takes away a piece of covering fabric, the output signal controls the lifting mechanism 220 to drive the lifting platform 210 to rise by a corresponding height, so that the top surface of the covering fabric on the placing area is always controlled at the same height. In this way, combined with the mechanical hand grabbing the fabric, precise positioning can be achieved.
