[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The specific implementation of the present application is described in detail below in conjunction with specific embodiments.

[0035] like Figure 1 As shown, an automatic feeding device for automobile interior production provided in an embodiment of the present application includes: a plate preheating device 100, a waiting rack 200, a fabric feeding device 400, a mounting rack 510 and a clamping device 300.

[0036] like Figure 1 As shown, the plate preheating device 100 includes an oven 120 and a conveyor belt 110, and the conveyor belt 110 passes through the heating chamber of the oven 120. The plate is placed on the feeding end of the conveyor belt 110 through a conveyor line or a robotic arm, and the conveyor belt 110 drives the plate into the heating chamber of the oven 120 for preheating. After the preheating is completed, the conveyor belt 110 continues to move to transport the plate to the waiting rack 200. The specific structures of the conveyor belt 110 and the oven 120 are all prior art and will not be repeated here.

[0037] like Figure 1 and Figure 3 As shown, the mounting frame 510 is located at the discharge end of the conveyor belt 110, and a guide rail 520 is arranged on the mounting frame 510. The waiting frame 200, the material feeding device 400, and the hot pressing station for placing the hot press machine 10 are arranged in sequence along the extension direction of the guide rail 520. The mounting frame 510 is welded by profiles, and includes four supporting legs and a rectangular frame located at the upper end of the supporting legs. The long sides of the rectangular frame are all provided with guide rails 520, and the two guide rails 520 are arranged in parallel. A sliding seat 311 cooperating with the guide rail 520 is arranged on the movable plate. Through the cooperation between the sliding seat 311 and the guide rail 520, the sliding frame 310 slides smoothly.

[0038] like Figure 3 and Figure 4 As shown, in some embodiments, a screw rod 530 is rotatably provided on the mounting frame 510, a nut member 312 matched with the screw rod 530 is fixedly provided on the sliding frame 310, and a driving motor for driving the screw rod 530 to rotate is provided on the mounting frame 510. Specifically, the screw rod 530 and the driving motor are transmitted to each other through a belt drive, and two screw rods 530 are provided in parallel, and the two screw rods 530 are transmitted to each other through a belt drive.

[0039] like Figure 1 and Figure 5 As shown, the clamping device 300 is slidably arranged on the guide rail 520, and the clamping device 300 includes two symmetrically arranged clamping head assemblies 301, and the clamping head assembly 301 includes a sliding frame 310 that is slidably matched with the guide rail 520. A lifting plate 320 is lifted and lowered on the sliding frame 310, and a first clamping member 330 is arranged on the lifting plate 320. A second clamping member 340 fixedly connected to the sliding frame 310 is arranged below the first clamping member 330. The first clamping member 330 has a first end surface on a side close to the second clamping member 340, and a plurality of negative pressure holes 332 are provided on the first end surface. A first cavity 331 connected to each negative pressure hole 332 is provided in the first clamping member 330, and the first cavity 331 is connected to the negative pressure generating device. A lifting driving device for driving the lifting plate 320 to lift and lower is arranged on the sliding frame 310. In some embodiments, the negative pressure generating device is a vacuum generator.

[0040] like Figure 6 As shown, in some embodiments, the lifting drive device includes a first gear 351 rotatably arranged on the lifting plate 320, the first gear 351 is driven by a first motor, a vertically arranged rack 352 is fixedly arranged on the lifting plate 320, the first gear 351 and the rack 352 are engaged for transmission, and when the first motor rotates, the lifting plate 320 is driven to move up and down through the engagement of the first gear 351 and the rack 352.

[0041] In the embodiment of the present application, the plate is put in from the feeding end of the conveyor belt 110. Driven by the conveyor belt 110, the plate is preheated by the oven 120, and then passes out from the unloading end of the conveyor belt 110 and falls on the waiting rack 200. The clamping device 300 slides along the guide rail 520 and passes through the fabric feeding device 400, and absorbs both sides of the fabric 20 through the negative pressure holes 332 of the two first clamping members 330. The clamping device 300 continues to move to the waiting rack 200, and the first clamping member 330 moves down to attach the fabric 20 to the plate and clamp the plate, and then the clamping device 300 moves along the guide rail 520 to the hot pressing station, and the plate and the fabric 20 are placed together in the hot press 10 for hot pressing. By setting a negative pressure hole 332 on the first clamping member 330 to absorb the fabric 20, the fabric 20 can be attached to the first clamping member 330. When the plate is clamped, the fabric 20 can be attached to the upper surface of the plate. In this way, the fabric 20 and the plate can be loaded through a set of clamping devices 300, simplifying the structure and reducing costs.

[0042] Reference Figure 6 and Fig. 9 As shown, in some embodiments of the present application, the first clamping member 330 is rotatably disposed on the lifting plate 320, and the lifting plate 320 is provided with a first driving device that drives the first clamping member 330 to rotate. When the first driving device drives the first clamping member 330 to rotate, the negative pressure holes 332 on the two clamping head assemblies 301 approach each other or move away from each other. The negative pressure hole 332 deviates from the rotation axis of the first clamping member 330, so that when the first clamping member 330 rotates relative to the lifting plate 320, the first end face and the negative pressure hole 332 can move around the rotation axis of the first clamping member 330, so that after the negative pressure hole 332 absorbs the fabric 20, the negative pressure holes 332 on the two first clamping members 330 move away from each other through the rotation of the two first clamping members 330, and the fabric 20 can be tensioned.

[0043] Specifically, Figure 5 and Figure 6As shown, the first driving device includes a second gear 361 fixedly connected to the first clamping member 330, the second gear 361 is coaxially arranged with the rotating shaft of the first clamping member 330, the lifting plate 320 is provided with a second motor, the rotating shaft of the motor is fixedly connected with a third gear 362, and the second gear 361 and the third gear 362 are meshed and driven. In this way, the second motor can drive the first clamping member 330 to rotate through gear transmission.

[0044] Reference Fig. 9 and Fig.10 As shown, in some embodiments of the present application, the first clamping member 330 is further provided with an end cap 610 located at the negative pressure hole 332, the end cap 610 is flush with the first end surface, and a plurality of ventilation holes 611 are evenly distributed on the end cap 610, and the diameter of the ventilation holes 611 is smaller than the negative pressure hole 332. It can be understood that by providing the end cap 610 on the negative pressure hole 332, it is possible to prevent the negative pressure hole diameter from being too large so that the fabric 20 is trapped in the negative pressure hole 332, and the wrinkles generated on the fabric 20 can be reduced. Specifically, as Fig. 9 As shown, the port of the negative pressure hole 332 is provided with a receiving groove, the diameter of which is slightly larger than the diameter of the negative pressure hole 332 , and the receiving groove is used to receive the end cover 610 so that the end cover 610 is flush with the first end surface.

[0045] In some embodiments of the present application, a needle 650 is movably provided on the end cover 610, and the needle 650 can extend out of the end cover 610 to protrude from the first end surface. It can be understood that when the negative pressure hole 332 absorbs some fabrics 20 with good air permeability, the absorption effect is not good, and it is difficult to absorb the fabric 20 steadily. The fabric 20 is pierced by the needle 650 on the end cover 610, and then the first clamping member 330 rotates to drive the needle 650 to move and tighten the fabric 20. In this way, the fabric 20 can be stably clamped on the first clamping member 330.

[0046] like Fig. 9 As shown, in some embodiments, the first clamping member 330 is further provided with a second end face 334 connected to the first end face, the first end face and the second end face 334 are equidistant from the rotation axis of the first clamping member 330, and the first end face and the second end face 334 are arranged at an angle, and preferably, the angle between the first end face and the second end face 334 is thirty degrees. It can be understood that when the first clamping member 330 rotates, the first end face rotates from a horizontal position to an inclined position, and the second end face 334 rotates to the original position of the first end face, so that when the plate is clamped, the needle 650 can avoid contact with the plate, and the needle 650 can be effectively protected.

[0047] like Fig. 9 and Fig.10As shown, in some embodiments of the present application, the needle 650 is slidably disposed on the end cover 610, and a piston cavity 621 is disposed on the end cover 610. A first piston member 630 is disposed in the piston cavity 621. The first piston member 630 divides the piston cavity 621 into a lower cavity and an upper cavity. The lower cavity is connected to the first cavity 331, and the upper cavity is connected to the atmosphere. The tail end of the needle 650 is fixedly disposed on the first piston member 630. When the first piston member 630 moves, it can drive the needle 650 to extend or retract the end cover 610. It can be understood that when the negative pressure generating device is working and negative pressure is generated in the first cavity 331, the negative pressure hole 332 absorbs the fabric 20 and makes it close to the end cover 610. At the same time, the lower cavity of the piston cavity 621 generates negative pressure due to being connected to the first cavity 331, and the first piston member 630 drives the needle 650 to go down and puncture the fabric 20. Furthermore, the negative pressure hole 332 draws the fabric 20 to move upward, and the needle 650 punctures downward, and the two move toward each other, thereby ensuring the reliability of the puncture.

[0048] like Fig. 9 and Fig.10 As shown, in some embodiments of the present application, a connecting hole 333 coaxially arranged with the negative pressure hole 332 is provided on the peripheral wall of the first cavity 331, and the center of the end cover 610 has a ring column portion 620, the inner cavity of the ring column portion 620 forms the piston cavity 621, the outer peripheral surface of the ring column portion 620 is threadedly connected to the inner peripheral surface of the connecting hole 333, and the end of the connecting hole 333 away from the ring column portion 620 is connected to the atmosphere. It can be understood that the installation of the end cover 610 can be realized by passing the ring column portion 620 through the negative pressure hole 332 and the first cavity 331 and then screwing it with the connecting hole 333, and the upper cavity can be connected to the atmosphere through the connecting hole 333, and the structure is simple and reliable, and it is easy to process.

[0049] like Fig.10 As shown, in some embodiments, the outer peripheral surface of the end cover 610 is provided with a mounting groove 612 , and the mounting tool is clamped in the mounting groove 612 , so as to facilitate the rotation and installation of the end cover 610 .

[0050] like Figure 8 , Fig. 9 and Fig.10As shown, in some embodiments of the present application, the connecting hole 333 is threadedly connected to the piston cylinder 710 at one end away from the end cover 610, and a second piston member 720 is slidably provided in the piston cylinder 710. The upper end of the piston cylinder 710 is connected to the atmosphere, and the lower end is connected to the upper cavity. A first contact is provided on the second piston member 720, and a second contact that cooperates with the first contact is provided below the second piston member 720. The second piston member 720 is connected to the top wall of the piston cylinder 710 by an elastic member. When the first contact and the second contact are in contact, the first driving device is controlled to drive the first clamping member to rotate.

[0051] It is understandable that when the first piston drives the needle 650 to descend, the pressure of the upper cavity decreases, the second piston member 720 moves downward and makes the first contact abut against the second contact, generating an electrical signal to control the second motor to drive the first clamping member 330 to rotate. When the pressure of the upper cavity is restored, the elastic member can pull the second piston member 720 back up. In this way, it can be ensured that the needle 650 is punctured before driving the motor to rotate, ensuring the reliability of the work. In some embodiments, the piston cylinder 710 and its internal parts are installed on only one connecting hole 333.

[0052] Specifically, refer to Fig. 9 As shown, in some embodiments, the second piston member 720 is provided with a first contact, a contact mounting member 730 is installed on the side wall of the piston cylinder 710, the contact mounting member 730 is located below the piston, and a second contact is provided on the contact mounting member 730. The first contact and the second contact are respectively electrically connected to the controller, and the controller is electrically connected to the second motor. The first contact contacts the second contact to generate an electrical signal, and the controller controls the second motor to drive the first clamping member 330 to rotate.

[0053] like Fig.10 As shown, the inner cavity of the annular column portion 620 includes a first cylindrical cavity and a second cylindrical cavity with a diameter smaller than that of the first cylindrical cavity. The first piston member 630 is disposed in the first cylindrical cavity. The peripheral wall of the second cylindrical cavity is provided with a first through hole 622 connected to the first cavity 331. The end of the first cylindrical cavity away from the second cylindrical cavity is threadedly connected to a limiting member 640. The limiting member 640 is provided with a second through hole 641 connecting the first cylindrical cavity and the connecting hole 333. It can be understood that the first piston member 630 can be lowered by the stepped surface of the first cylindrical cavity and the second cylindrical cavity, and the first piston can be upper-positioned by the limiting member 640 to ensure stable operation of the piston. Specifically, as shown in FIG. Fig.10 As shown, the upper inner wall of the second cylindrical cavity is provided with a thread, and the stopper 640 is threadedly connected to one end of the second cylindrical cavity. The stopper 640 is provided with a second through hole 641 to connect the upper cavity with the connecting hole 333, thereby realizing the connection between the upper cavity and the atmosphere.

[0054] like Figure 7 As shown, in some embodiments of the present application, the second clamping member 340 is provided with a plurality of air outlet holes 342 at intervals along its length direction, and the second clamping member 340 is provided with a second cavity 341 connected to each of the air outlet holes 342, and the second cavity 341 is connected to the air compressor. It can be understood that air is blown toward the fabric 20 through the air outlet holes 342, so that the fabric 20 is close to the first clamping member 330, ensuring that the fabric 20 enters the suction range of the negative pressure hole 332, and stable suction is achieved.

[0055] like Figure 2 As shown, in some embodiments of the present application, the fabric feeding device 400 includes a lifting cylinder 420 disposed above the guide rail 520, a connecting frame 430 is disposed at the output end of the lifting cylinder 420, a grabbing member 440 for grabbing the fabric 20 is disposed on the connecting frame 430, and a placing frame 411 for placing the fabric 20 is disposed below the connecting frame 430, and the height of the placing frame 411 is lower than the guide rail 520. Specifically, the lifting cylinder 420 is installed at the top of the frame 410, and the middle section of the frame 410 is formed with a placing frame 411 for placing the fabric 20, and the guide rail 520 passes through the frame 410 from above the placing frame 411. It can be understood that the lifting cylinder 420 drives the connecting frame 430 to descend, the grabbing member 440 grabs the fabric 20, and the lifting cylinder 420 rises back to bring the fabric 20 to a position suitable for the clamping device 300 to clamp. In some embodiments, the grabbing member 440 can be a suction cup or a hook surface of Velcro.

[0056] In the embodiment of the present application, the plate is put in from the feeding end of the conveyor belt 110. Driven by the conveyor belt 110, the plate is preheated by the oven 120, and then passes out from the unloading end of the conveyor belt 110 and falls on the waiting rack 200. The clamping device 300 slides along the guide rail 520 through the fabric feeding device 400, and absorbs both sides of the fabric 20 through the negative pressure holes 332 of the two first clamping members 330. The clamping device 300 continues to move to the waiting rack 200, and the first clamping member 330 moves down to attach the fabric 20 to the plate and clamp the plate, and then the clamping device 300 moves along the guide rail 520 to the hot pressing station, and the plate and the fabric 20 are placed together in the hot press 10 for hot pressing. By setting a negative pressure hole 332 on the first clamping member 330 to absorb the fabric 20, the fabric 20 can be attached to the first clamping member 330. When the plate is clamped, the fabric 20 can be attached to the upper surface of the plate. In this way, the fabric 20 and the plate can be loaded through a set of clamping devices 300, simplifying the structure and reducing costs. In addition, the fabric 20 is pierced by the needle 650 on the end cover 610, and then the first clamping member 330 rotates to drive the needle 650 to move and tighten the fabric 20. In this way, the fabric 20 can be stably clamped on the first clamping member 330.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
