[0025] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the embodiments of the present application, and are not intended to limit the protection scope of the embodiments of the present application.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0027] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "front and back", "left and right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0028] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figures 1 to 6As shown, the embodiment of the present application discloses an automatic composite feeding device for automobile ceiling fabrics, including a rectangular frame 1, and the left and right directions of the frame 1 in the drawing direction are the length direction, and the front and back directions are the width direction.

[0030] The frame 1 is provided with a support plate 2 which is generally rectangular and is used to place the fabric horizontally. The support plate 2 is provided with clamping components on both sides in the width direction for clamping the front and rear sides of the fabric on the support plate 2. The frame 1 is also provided with a material transfer driving component for driving the two clamping components to move back and forth between the cutting mechanism 3 and the compound mold 4 respectively, so as to realize the automatic transfer of the fabric on the support plate 2 to the compound station. The automated transfer structure replaces the manual transfer in the prior art, with high loading efficiency and labor cost saving. In addition, in this structure, a pulling component for pulling the cut fabric to the support plate 2 is also provided on the side of the frame 1 close to the automatic cutting mechanism 3, so as to further improve the degree of automation of the fabric from high cutting to transfer to the compound mold 4. The whole process basically does not require human participation, which not only improves work efficiency but also avoids errors caused by human factors, such as errors in the forward and reverse directions of the fabric.

[0031] In this embodiment, the two material moving drive assemblies have the same structure, and they both include mounting seats 5. The two mounting seats 5 are slidably connected to the two sides of the width direction of the frame bottom plate 6 along the length direction of the frame 1. Specifically, the two mounting seats 5 are slidably connected to the front and rear sides of the frame bottom plate 6 through two sets of linear slide rails, and the two sets of linear slide rails are arranged parallel to each other; in addition, a dual-output motor 7 is arranged in the middle of one end of the length direction of the frame bottom plate 6, and the two power output shafts of the dual-output motor 7 are connected to the first driving wheel 8, and the other end of the frame bottom plate 6 in the length direction is provided with two first driven wheels 9 corresponding to the two first driving wheels 8, and a first conveying belt 10 is connected between the two first driving wheels 8 and the first driven wheel 9, the two mounting seats 5 are respectively connected to the two first conveying belts 10, and the two material clamping assemblies are respectively connected to the two mounting seats 5. In this structure, a pulley structure is used to provide power for the movement of the two mounting seats 5, and the drive is smooth and the noise is low. In addition, the two mounting seats 5 are slidably matched with the frame bottom plate 6 through linear slide rails, which further improves the stability of the movement of the two mounting seats 5 between the cutting mechanism 3 and the composite mold 4.

[0032] In this embodiment, see the attached Figure 2 , 3and 6, the clamping assembly structures on both sides of the width direction of the support plate 2 are also the same and can be replaced with each other; preferably, the clamping assembly includes a plurality of first clamping jaws 11 spaced apart along the length direction of the fabric and a plurality of first clamping jaw cylinders 12 for driving the first clamping jaws 11 to open and close. More specifically, the plurality of first clamping jaws 11 are respectively connected to the pneumatic fingers of the plurality of first clamping jaw cylinders 12, that is, the opening and closing control of the plurality of first clamping jaws 11 can be achieved by controlling the airflow in the first clamping jaw cylinders 12, the structure is simple, the clamping is convenient, and the pneumatic components are neater than the hydraulic components and will not cause fabric contamination.

[0033] In the above structure, when the pulling component drives the fabric to move onto the support plate 2, the two sides of the fabric in the width direction are flush with the two sides of the support plate 2, so that the fabric can be ensured to be completely flat. If the two sides of the fabric in the width direction exceed the two sides of the support plate 2, it is easy to cause the two sides of the fabric in the width direction to deform downward, affecting the normal clamping of the clamping component and causing a decrease in work efficiency. Although the special design here can ensure the flatness of the fabric, it becomes a new problem if the clamping of the first clamping jaw 11 is ensured. For this reason, in this embodiment, avoidance openings 13 are provided at positions corresponding to the first clamping jaws 11 on both sides of the width direction of the support plate 2, so that when the first clamping jaws 11 are closed, they can avoid the main body of the support plate 2 and stably clamp the fabric on the upper and lower sides, see the attached Figure 5 In addition, in this structure, a lifting drive unit is provided on the two mounting seats 5 for driving each first clamping jaw 11 to lift and lower respectively. Here, when multiple first clamping jaws 11 clamp the fabric, the lifting drive unit is used to drive the first clamping jaws 11 to lift and lower to avoid the support plate 2, so as to facilitate the subsequent translation along the length direction of the frame 1 and ensure that there is no interference from other components during the movement process.

[0034] Furthermore, in this embodiment, the clamping assembly further includes a vertically arranged fixed plate 14, a plurality of first clamping jaw cylinders 12 are connected to one side of the fixed plate 14 close to the support plate 2, and each first clamping jaw 11 is respectively connected to the pneumatic finger of each first clamping jaw cylinder 12; the other end of the fixed plate 14 is slidably connected to the mounting seat 5, and the lifting drive unit is used to drive the fixed plate 14 to rise and fall to drive each first clamping jaw 11 to rise and fall. In this structure, see the attached Figure 2 The fixed plate 14 is slidably connected by two sets of mutually parallel linear slide rails to ensure that the fixed plate 14 can be lifted and lowered more smoothly.

[0035] See attached Figure 3The lifting drive unit includes a driving gear 15, a rack 16 and a lifting motor 17. The lifting motor 17 is connected to the mounting base 5. The driving gear 15 is connected to the output shaft of the lifting motor 17. The rack 16 is vertically connected to the side of the fixed plate 14 away from the support plate 2 and meshes with the driving gear 15. In this embodiment, preferably, two spaced racks 16 are connected to the outer wall of the fixed plate 14 away from the support plate 2. Correspondingly, two spaced driving gears 15 are connected to the output shaft of the lifting motor 17, and the two driving gears 15 are meshed and transmitted with the two racks 16 in a one-to-one correspondence. The two sets of gear and rack 16 driving structures can better ensure that the fixed plate 14 drives the multiple first jaw cylinders 12 to rise and fall smoothly.

[0036] On the other hand, see Appendix Figure 2 , 3 The material pulling assembly includes a portal bracket 18, and a plurality of second clamping cylinders 19 for clamping the fabric are connected to the crossbeam of the portal bracket 18, and the pneumatic fingers of each second clamping cylinder 19 are connected to a second clamping claw 20 for clamping the fabric; the crossbeam is also connected to a translation drive assembly for driving each second clamping cylinder 19 to move along the fabric pulling direction; the frame 1 is also provided with a material pulling drive unit for driving the portal bracket 18 to move along its length direction.

[0037] More specifically, in the above structure, a horizontally arranged mounting frame 21 and a translation drive cylinder 22 are connected to the lower end of the beam. The mounting frame 21 is slidably connected to the beam along the conveying direction of the fabric through a linear slide rail, and the driving end of the translation drive cylinder 22 is connected to the mounting frame 21; a plurality of second clamping cylinders 19 are connected to one end of the mounting frame 21 close to the cutting mechanism 3.

[0038] See attached Figure 4 The material pulling drive unit includes two second driving wheels 23 and two second driven wheels 24 which are respectively arranged at both ends of the frame 1 in the length direction and spaced apart along the width direction thereof, and a second conveying belt 25 is connected between the two second driving wheels 23 and the second driven wheels 24. A material pulling motor 26 for simultaneously driving the two first driving wheels 8 to rotate is provided on the frame 1; the two upright posts of the door-type bracket 18 are respectively slidably connected to the frame 1 through linear slide rails, and are respectively connected to the two second conveying belts 25.
