[0026] In this embodiment, a car roof covering device is provided for covering a car roof frame with a car roof covering fabric.

[0027] Figure 1 Schematic diagram of a car roof frame in an embodiment of the present invention.

[0028] like Figure 1 As shown, the automobile roof frame A1 includes a first frame A11, a second frame A12 and a third frame A13. The two ends of the first frame A11 are respectively connected to one end of the second frame A12 and the third frame A13. The second frame A12 and the third frame A13 have a curvature, that is, the middle part of the second frame A12 and the third frame A13 is convex, so that the automobile roof frame A1 has a convexity.

[0029] Figure 2 It is a block diagram of a vehicle roof covering device in an embodiment of the present invention.

[0030] like Figure 2 As shown, the automobile roof covering device 100 includes a glue spraying mechanism 10, a frame conveying mechanism 20, a fabric cutting mechanism 30, a fabric conveying mechanism 40, a covering mechanism 50, a heating mechanism 60 and an automobile roof covering control mechanism 70.

[0031] The glue spraying mechanism 10 is used to spray glue on the automobile roof frame A1 to obtain the automobile roof frame A1 that has been pre-sprayed with glue.

[0032] The frame conveying mechanism 20 is used to move the automobile roof frame A1 to a first designated position. The protrusion of the automobile roof frame A1 located at the first designated position faces downward.

[0033] The fabric cutting mechanism 30 is used to cut the original fabric into fabric for covering the automobile roof and place it at a preset bearing position.

[0034] The fabric conveying mechanism 40 is used to move the automobile roof covering fabric from a preset loading position to a second designated position.

[0035] Figure 3 Schematic diagram of the structure of the fabric conveying mechanism in the embodiment of the present invention.

[0036] like Figure 3 As shown, the fabric conveying mechanism 40 includes a fixed frame assembly 41 , a driven frame assembly 42 and an active frame assembly 43 .

[0037] The fixed frame assembly 41 includes a first fixed bracket 411 and a second fixed bracket 412 parallel to each other, an active frame rail 413 , a driven frame rail 414 and a toothed driving rail 415 .

[0038] Figure 4 It is a structural schematic diagram of one side of a fixed frame assembly in an embodiment of the present invention.

[0039] like Figure 4 As shown, an active frame rail 413 , a driven frame rail 414 and a toothed driving rail 415 are respectively provided on a first fixed bracket 411 on one side of the fixed frame assembly 41 .

[0040] The active frame rail 413 is a linear slide rail.

[0041] Two ends of the driven frame rail 414 are the preset bearing position and the second designated position.

[0042] The driven frame track 414 includes a first linear sub-track 4141 having a groove and a second linear sub-track 4142. One end of the first sub-track 4141 is connected to one end of the second sub-track 4142, and the angle between the first sub-track 4141 and the second sub-track 4142 is a preset angle.

[0043] In this embodiment, the preset angle is an obtuse angle, and the connection between the first sub-track 4141 and the second sub-track 4142 is a smooth connection, that is, the connection is an arc-shaped smooth corner.

[0044] The toothed driving rail 415 is a linear guide rail with a rack on one side, and the rack is located on the upper side of the linear guide rail.

[0045] The active frame rail 413 , the driven frame rail 414 and the toothed driving rail 415 are sequentially arranged on the first fixing bracket 411 from top to bottom, and the active frame rail 413 , the first sub-rail 4141 and the toothed driving rail 415 are arranged in parallel.

[0046] In this embodiment, the second fixed bracket 412 on the other side of the fixed frame assembly 41 is also provided with an active frame rail 413, a driven frame rail 414 and a toothed driving rail 415, and is mirror-symmetrically arranged with one side of the first fixed bracket 411, and the specific structure is not repeated.

[0047] Figure 5 Schematic diagram of the structure of the driven frame assembly in an embodiment of the present invention.

[0048] like Figure 5 As shown, the driven frame assembly 42 includes a driven frame 421 , a relative displacement track 422 and a pulley 423 .

[0049] Two relative displacement tracks 422 and a pulley 423 are disposed on opposite sides of the driven frame assembly 42 , and the relative displacement tracks 422 and the pulley 423 on the two sides are disposed in a mirror-symmetrical manner.

[0050] The relative displacement rails 422 located on the same side of the driven frame assembly 42 are arranged parallel to each other and extend in the vertical direction.

[0051] The two pulleys 423 are respectively disposed at the lower parts of both sides of the driven frame 421 , and slide in the corresponding driven frame rails 414 , so that the moving track of the driven frame assembly 42 is consistent with the track of the driven frame rails 414 .

[0052] Figure 6 Schematic diagram of the structure of the active frame assembly in an embodiment of the present invention.

[0053] like Figure 6 As shown, the active frame assembly 43 includes an active frame 431 , a driving motor 432 , a driving rod 433 , a driving gear 434 , an active slider 435 and a driven slider 436 .

[0054] The active frame 431 includes a first connecting plate 4311 , a second connecting plate 4312 , a third connecting plate 4313 and a driving bearing plate 4314 .

[0055] Two ends of the first connecting plate 4311 are connected to one end of the second connecting plate 4312 and one end of the third connecting plate 4313 respectively. In this embodiment, the connection is further fixed by a triangular plate.

[0056] One long side of the first connecting plate 4311 is fixedly connected to one long side of the driving supporting plate 4314 , and two ends of the driving supporting plate 4314 are respectively connected to one end of the second connecting plate 4312 and one end of the third connecting plate 4313 .

[0057] The driving motor 432 is disposed on the driving bearing plate 4314 and connected to the driving rod 433 .

[0058] The two driving gears 434 are fixedly connected to the two ends of the driving rod 433 respectively, and the two driving gears 434 are respectively gear-engaged with the corresponding toothed driving rails 415 through the through holes on the second connecting plate 4312 and the third connecting plate 4313 .

[0059] The driving motor 432 drives the driving rod 433 to rotate forward and reversely, so that the driving gear 434 moves back and forth on the toothed driving track 415 .

[0060] The second connecting plate 4312 is provided with one side facing the first fixed bracket 411, and the third connecting plate 4313 is provided with one side facing the second fixed bracket 412, respectively. The three active sliding blocks 435 on the same surface are respectively provided at the front end, the middle end and the rear end of the corresponding connecting plate, and are located in the same straight line. Each active sliding block 435 is slidably connected to the corresponding active frame rail 413, so that the active frame assembly 43 moves along the active frame rail 413.

[0061] Two driven sliders 436 are respectively provided on one side of the second connecting plate 4312 and the third connecting plate 4313 facing the driven frame assembly 42. The two driven sliders 436 on the same surface are spaced as far apart as possible, so that the force on the corresponding connecting plates is more uniform. Each driven slider 436 is slidably connected to the corresponding relative displacement track 422, so that the driven frame assembly 42 moves relative to the active frame assembly 43 along the relative displacement track 422.

[0062] The specific movement mode of the driven frame assembly 42 is:

[0063] When the driven frame assembly 42 slides along the first sub-track 4141 , the driven frame assembly 42 and the active frame assembly 43 are relatively stationary; when the driven frame assembly 42 slides along the second sub-track 4142 , the driven frame assembly 42 and the active frame assembly 43 move relative to each other through the relative displacement track 422 .

[0064] The driven frame assembly 42 moves in the second sub-track 4142 in the above-mentioned moving manner, and simultaneously moves along the direction of the relative displacement track 422 and the active frame track 413 , thereby shortening the time from one end of the second sub-track 4142 to the other end.

[0065] In addition, the second sub-track 4142 corresponds to the position of the protrusion of the automobile roof frame A1, that is, when the automobile roof covering fabric supported by the driven frame assembly 42 moves along the second sub-track 4142, it can effectively avoid interference with the protrusion of the automobile roof frame A1.

[0066] In summary, the movement of the driven frame assembly 42 along the driven frame track 414 can make the conveying speed of the automobile roof covering fabric faster and avoid accidental contact with the protrusions of the automobile roof frame A1.

[0067] The covering mechanism 50 comprises a clamping assembly 51 and an upper mold assembly 52. ​​The clamping assembly 51 is used to clamp the automobile ceiling covering fabric at the second designated position and place it on the upper mold assembly 52.

[0068] The heating mechanism 60 is used to heat the pre-sprayed automobile roof frame A1 at the first designated position.

[0069] The automobile roof covering control mechanism 70 stores a control program for controlling the operation of each mechanism.

[0070] Figure 7 It is a schematic diagram of the process of laminating the automobile roof according to the original fabric and the automobile roof frame in an embodiment of the present invention.

[0071] like Figure 7 As shown, the automobile roof covering control mechanism 70 controls various mechanisms to cover the automobile roof according to the original fabric and the automobile roof frame, including the following steps:

[0072] Step S1 : the automobile roof covering control mechanism 70 controls the glue spraying mechanism 10 to spray glue on the automobile roof frame A1 , so as to obtain the automobile roof frame A1 which is pre-sprayed with glue.

[0073] Step S2 , the automobile roof covering control mechanism 70 controls the frame conveying mechanism 20 to move the automobile roof frame A1 sprayed with glue in advance to a first designated position.

[0074] In step S3, the automobile roof covering control mechanism 70 controls the fabric cutting mechanism 30 to cut the original fabric into fabric for automobile roof covering, and places the original fabric on the fabric conveying mechanism 40 located at a preset load position.

[0075] In step S4, the automobile roof covering control mechanism 70 controls the fabric conveying mechanism 40 to move the automobile roof covering fabric from the preset carrying position to the second designated position.

[0076] Step S5 , the automobile ceiling covering control mechanism 70 controls the clamping assembly 51 to clamp the automobile ceiling covering fabric at the second designated position and place it on the upper mold assembly 52 .

[0077] Step S6 , the automobile roof covering control mechanism 70 controls the heating mechanism 60 to heat the pre-sprayed automobile roof frame A1 at the first designated position.

[0078] Step S7, the automobile roof covering control mechanism 70 controls the upper mold assembly 52 to move so that the automobile roof covering fabric is covered with the heated automobile roof frame A1. In this embodiment, the lower part of the upper mold assembly 52 is the first designated position, and the automobile roof covering control mechanism 70 controls the upper mold assembly 52 to descend so that the automobile roof covering fabric is covered with the heated automobile roof frame A1.
