DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] For example, see Figure 1-Figure 10 A door panel processing and flipping device for automatically transporting materials includes a first roller conveyor 200 for conveying door panels 100. Several door panels 100 are arranged and stacked. A first base 500 is arranged between the several door panels 100 and the first roller conveyor 200. Two feeding mechanisms 600 and a first flipping mechanism 700 are arranged on the first base 500. The feeding mechanism 600 includes a first mounting seat 610. A first clamp assembly 620 and a second clamp assembly 630 are arranged on the first mounting seat 610. The feeding mechanism 600 also includes a displacement assembly 640 and a push assembly 650.

[0039] The uppermost door panel 100 is pushed to the exposed end by the pushing assembly 650, and then one end of the door panel 100 is clamped by the first clamp assembly 620. Then, the two first mounting seats 610 are driven to rotate and lift the door panel 100 by the first flipping mechanism 700. At the same time, the two displacement assemblies 640 drive the two second clamp assemblies 630 to move to the other end of the door panel 100 for clamping. Then, the door panel 100 is turned over by the first flipping mechanism 700 and placed on the first roller conveyor 200.

[0040] It also includes a second roller conveyor 300 , and a second flipping mechanism 400 is arranged between the first roller conveyor 200 and the second roller conveyor 300 . The second flipping mechanism 400 is used to flip the door panel 100 on the first roller conveyor 200 and place it on the second roller conveyor 300 .

[0041] The second turning mechanism 400 includes a second base 410 , on which a first motor 420 is disposed, on which an output shaft of the first motor 420 is disposed a transfer frame 430 , on which a material trough 440 is provided.

[0042] The second clamp assembly 630 includes a slide seat 631 slidably disposed on the first mounting seat 610 . Two slide grooves 632 are symmetrically provided on the slide seat 631 . Clamping claws 633 are slidably disposed in the two slide grooves 632 .

[0043] A first cylinder 634 is disposed on the sliding seat 631 , a first connecting shaft 635 is disposed on the piston rod of the first cylinder 634 , and a connecting seat 636 is disposed on each of the two clamping jaws 633 .

[0044] The second clamp assembly 630 further includes two first connecting rods 637 , one ends of the two first connecting rods 637 are rotatably disposed on the first connecting shaft 635 , and the other ends of the two first connecting rods 637 are rotatably disposed on two connecting seats 636 .

[0045] The structure of the first clamp assembly 620 is consistent with that of the second clamp assembly 630 , and the position of the first clamp assembly 620 on the first mounting seat 610 is fixed.

[0046] The first base 500 is provided with a bearing mechanism 800 and a second cylinder 900 . The bearing mechanism 800 includes a lifting seat 810 slidably disposed on the first base 500 . The piston rod of the second cylinder 900 is connected to the lifting seat 810 .

[0047] Two second mounting seats 820 are symmetrically arranged on the lifting seat 810 . The first flipping mechanism 700 includes two rotating drums 730 . The two first mounting seats 610 are rotatably connected to the two second mounting seats 820 through the two rotating drums 730 .

[0048] In this embodiment: on the door panel processing production line, the rough door panel 100 can be transferred manually or by a forklift and stacked on the left side of the first base 500, and the loading process on the first base 500 is automated.

[0049] First, the second cylinder 900 controls the lifting seat 810 to move up and down, so that the two first mounting seats 610 are aligned with the uppermost door panel 100. Since it is not easy to remove a single layer of door panels 100 stacked together, a push assembly 650 is provided to push the uppermost door panel 100 to the left by a certain distance, so that the left end of the door panel 100 leaks out. At this time, the left end of the door panel 100 passes through the second clamp assembly 630 and the four pairs of clamps of the first clamp assembly 620 in sequence.

[0050] The structure of the first clamp assembly 620 is the same as that of the second clamp assembly 630, but the first clamp assembly 620 is fixed on the first mounting seat 610. First, the piston rod is extended through the structure corresponding to the first cylinder 634 in the first clamp assembly 620, and the two connecting seats 636 are moved closer through the transmission of the first connecting shaft 635 and the two first connecting rods 637, so that the upper clamping claw 633 moves down along the sliding groove 632, and the lower clamping claw 633 moves up along the sliding groove 632, and the two clamping claws 633 clamp the left end of the door panel 100.

[0051] Then, the first flipping mechanism 700 drives the two rotating drums 730 to rotate synchronously clockwise on the two second mounting seats 820, and the two rotating drums 730 drive the two first mounting seats 610 to rotate clockwise. At this time, since the left end of the door panel 100 is clamped by the first clamp assembly 620, the door panel 100 is also lifted up.

[0052] At the same time, the second clamp assembly 630 is driven to move right through the displacement assembly 640, and the door panel 100 is lifted clockwise from the left end. Finally, the two second clamp assemblies 630 reach the right end of the door panel 100, and then the right end of the door panel 100 is clamped by the two second clamp assemblies 630.

[0053] Then the first flip mechanism 700 continues to drive the two first mounting seats 610 to rotate clockwise, and the door panel 100 will follow the clockwise circular motion, and after flipping half a circle, it will reach the upper side of the first roller conveyor 200. At this time, the four pairs of clamps are controlled to release the door panel 100, and the bearing mechanism 800 controls the two second mounting seats 820 to move away from each other in the left and right directions, so that the door panel 100 falls on the first roller conveyor 200.

[0054] The first roller conveyor 200 and the second roller conveyor 300 can be driven by a motor to rotate a plurality of conveying rollers, and utilize friction to convey the door panel 100 to the right. The first roller conveyor 200 and the second roller conveyor 300 are conventional technical means, and their specific structures and working principles are not described in detail.

[0055] The first roller conveyor 200 may be provided with a device related to the first processing step of the door panel 100. After the first processing, when the first roller conveyor 200 conveys the door panel 100 to the right to the second turning mechanism 400, the cross-shaped transfer rack 430 stays at the second turning mechanism 400. Figure 1 In the state shown, the door panel 100 is inserted to the right into a material trough 440 opened on the left side of the transfer frame 430, and then the first motor 420 drives the transfer frame 430 to rotate half a circle clockwise, so that the door panel 100 can be flipped onto the second roller conveyor 300, and then the second roller conveyor 300 runs to continue to convey the door panel 100 to the right for subsequent processing steps.

[0056] After the door panel 100 located at the uppermost side is transported away, the lifting seat 810 can be driven to descend a certain distance by the second cylinder 900, and then the above steps are repeated to flip the second door panel 100 onto the first roller conveyor 200.

[0057] Embodiment 2: This embodiment is an improvement on Embodiment 1. For details, please refer to Figure 2-Figure 10 A second motor 830 is disposed on the lifting seat 810 , a gear 840 is disposed on the output shaft of the second motor 830 , and racks 850 are disposed on the two second mounting seats 820 , and the two racks 850 are meshed with the gear 840 .

[0058] The first flipping mechanism 700 also includes a support base 710 and a third motor 740 arranged on the lifting base 810. A rotating rod 720 is rotatably arranged on the support base 710. Two rotating drums 730 are respectively slidably connected to the two ends of the rotating rod 720. The output shaft of the third motor 740 is connected to the rotating rod 720 through a belt transmission device 750.

[0059] In this embodiment: the positions of the two second mounting seats 820 are not fixed. On the one hand, when the door panel 100 is flipped to the upper side of the first roller conveyor 200, the door panel 100 can be removed by moving the two second mounting seats 820 away from each other. On the other hand, the distance between the two second mounting seats 820 can also be controlled to adapt to the conveying of door panels 100 of different sizes.

[0060] Furthermore, considering that the door panels 100 may not be stacked neatly, before transportation, the uppermost door panels 100 may be aligned to the middle position by moving the two second mounting seats 820 closer together.

[0061] Specifically, the second motor 830 drives the gear 840 to rotate clockwise, and the racks 850 meshing on the left and right sides of the gear 840 are driven by the gear 840, and the second mounting seat 820 located at the front side moves backward under the drive of the rack 850 on the right side, and the second mounting seat 820 located at the rear side moves forward under the drive of the rack 850 on the left side. Similarly, when the second motor 830 drives the gear 840 to rotate counterclockwise, the two second mounting seats 820 move away from each other.

[0062] The front and rear ends of the rotating rod 720 are deformable, and the opening of the rotating cylinder 730 fits with the rotating rod 720. When the two rotating cylinders 730 move forward and backward with the two second mounting seats 820, the two rotating cylinders 730 slide forward and backward along the rotating rod 720, but it does not affect the transmission between the rotating rod 720 and the two rotating cylinders 730.

[0063] When the third motor 740 is running, the rotating rod 720 can be driven to rotate through the transmission of the belt transmission device 750, and the rotating rod 720 drives the two rotating drums 730 and the two first mounting seats 610 to rotate. The belt transmission device 750 can be composed of two pulleys respectively installed on the output shaft of the third motor 740 and the rotating rod 720, and a belt.

[0064] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 2-Figure 10 The displacement assembly 640 includes a second connecting shaft 641 arranged on the sliding seat 631, a guide groove 644 is opened on the second mounting seat 820, a sliding rod 642 is slidably arranged in the guide groove 644, and the displacement assembly 640 also includes a second connecting rod 643, and the two ends of the second connecting rod 643 are respectively rotatably connected to the second connecting shaft 641 and the sliding rod 642.

[0065] A first driving rod 645 is disposed on the rotating drum 730 , a second driving rod 646 is slidably disposed on the first driving rod 645 , and the second driving rod 646 is rotatably connected to the sliding rod 642 .

[0066] The guide groove 644 includes a protruding section 6441 and an arc section 6442 which are connected to each other. The center of the arc section 6442, the center of the first driving rod 645 and the center of the rotating drum 730 are all coaxial.

[0067] The pushing assembly 650 includes a pushing plate 651 and a third cylinder 652 which are arranged on the lifting seat 810 . The piston rod of the third cylinder 652 is connected to the pushing plate 651 .

[0068] In this embodiment: the push plate 651 is driven to move leftward by the third cylinder 652, and the left end of the push plate 651 will push the door panel 100 located at the uppermost side to move leftward out of the left end, and then the push plate 651 is controlled to reset.

[0069] When the drum 730 rotates clockwise, the first driving rod 645 connected thereto also rotates clockwise, and the first driving rod 645 then drives the second driving rod 646 and the sliding rod 642 to move clockwise. Since the sliding rod 642 slides in the guide groove 644, the sliding rod 642 moves clockwise along the track of the guide groove 644, and during this process, the second driving rod 646 slides relative to the first driving rod 645.

[0070] like Figure 7 As shown, when the second clamp assembly 630 is located on the left side of the first mounting seat 610, the slide bar 642 is located in the middle of the raised section 6441. When the rotating drum 730 rotates clockwise, the first mounting seat 610 rotates clockwise based on the rotating drum 730, and the slide bar 642 moves clockwise along the raised section 6441. During the rotation process, the relative positions of the slide bar 642 and the second connecting shaft 641 change, and the distance between the two is lengthened, while the length of the second connecting rod 643 is fixed, so the second connecting rod 643 pulls the slide 631 to slide along the first mounting seat 610 toward the rotating drum 730, so that the second clamp assembly 630 slides toward the right end of the door panel 100.

[0071] Until the second clamp assembly 630 clamps the right end of the door panel 100, the sliding rod 642 slides from the raised section 6441 to the arc section 6442, and then the sliding rod 642 slides clockwise along the arc section 6442. At this time, the relative positions of the sliding rod 642 and the second connecting shaft 641 are fixed, and the position of the second clamp assembly 630 will not change during the rotation.

[0072] After the first door panel 100 is transferred, the third motor 740 drives the rotating rod 720 to rotate counterclockwise, so that the two first mounting seats 610 rotate counterclockwise to reset, and the sliding rod 642 returns to the raised section 6441 along the arc section 6442, so that the second clamp assembly 630 moves left and resets.

[0073] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0074] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
