[0037] Specifically, the present invention installs multiple groups of suction cup assemblies 3 at the bottom of the frame 2, and the suction cup assemblies 3 at the four corners of the bottom of the frame 2 are slidably installed on the guide tube 4, and the outer end of the guide tube 4 can slide along the length direction of the front and rear beams of the frame 2 through the driving of the sliding mechanism 7, so that the horizontal guide tube 4 can swing horizontally, and the hinged driving mechanism 6 can not only make the guide tubes 4 corresponding to the two ends swing in a movable hinged state, but also drive the suction cup assemblies 3 at the corners to slide along the guide tube 4 after the horizontal swing, and the sliding suction cup assemblies 3 can stop at will on the guide tube 4 where the swing stops, so as to adjust the positions of the suction cup assemblies 3 at the four corners of the bottom of the frame 2, so that the multiple suction cup assemblies 3 can not only be distributed in a square shape at the bottom of the frame 2 to realize the adsorption and destacking of rectangular or square plates, but also can be distributed in a polygonal shape to realize the destacking and loading of polygonal and irregular plates, which can not only safely adsorb, destacker and load irregular plates, but also increase the scope of use and the wide range of use of the loading equipment.

[0038] In this embodiment, the suction cup assembly 3 includes a mounting block 31, and multiple mounting blocks 31 are all located on the bottom surface of the frame 2, and a cylinder member 32 is fixedly provided at the bottom of the mounting block 31, and a suction cup member 33 is installed on the output rod of the cylinder member 32, and each suction cup member 33 is connected to an air guide hose 34; specifically, except for the suction cup assemblies 3 at the four corners of the bottom surface of the frame 2, the other suction cup assemblies 3 are fixedly connected to the bottom surface of the frame 2 through the mounting block 31. The design of the cylinder member 32 can drive the suction cup member 33 to rise or fall, so that the suction cup member 33 can stably and accurately fit the plate to be destacking and loading, and the air guide hose 34 is connected with the air pump to achieve accurate adsorption, destacking and loading of the plate.

[0039] In this embodiment, a guide cavity 41 is provided at the bottom of the guide tube 4 along its length direction, a sliding block 42 is slidably provided in the guide tube 4, and the bottom of the sliding block 42 is connected to the suction cup assembly 3 through the cooperation of a sleeve and a rotating shaft 73, and the two ends of the guide tube 4 are respectively connected to the hinge drive mechanism 6 and the drive sliding mechanism 7;

[0040] Specifically, when the front and rear horizontal state guide tube 4 is driven and adjusted to the beveled state by the driving sliding mechanism 7, the hinged driving mechanism 6 will drive the sliding block 42 to slide in the guide tube 4, and the sliding block 42 extending out of the guide cavity 41 will drive the rotating connected suction cup assembly 3 to slide synchronously, so that the suction cup assembly 3 at the corner can slide along the length direction of the guide tube 4 in the beveled state, and at the same time, driven by the swinging guide tube 4, it can stop at any point under the triangular area surrounded by the swinging guide tube 4, the front and rear side beams and the left and right side beams of half of the frame 2, so that the suction cup assembly 3 at the four corners is not limited to moving in the front and rear or left and right straight directions on the lower surface of the frame 2, and can also move in the diagonal and arc directions, so as to increase the moving area of ​​the adsorption assembly at the four corners on the lower surface of the frame 2, so as to improve the versatility of the feeding equipment in sucking, destacking and feeding irregular plates.

[0041] In this embodiment, the two articulated drive mechanisms 6 are respectively located at the middle of the lower bottom surface on the left and right sides of the frame 2. The articulated drive mechanism 6 includes a box body 61, which is fixedly arranged at the middle of the lower bottom surface of the frame 2, and a suction cup member 33 is installed at the bottom of the box body 61. A winding drum 62 is symmetrically rotated and installed in the box body 61, and a wire rope 63 is wound around the winding drum 62. A U-shaped seat 64 is fixedly arranged on the front and rear sides of the box body 61, and a positioning ball 641 is installed on the upper wall of the U-shaped seat 64, and a push ball 651 is installed on its lower wall through a threaded rod 65, and a hinge block 66 is movably arranged in the U-shaped seat 64. , and the upper and lower surfaces of the hinge block 66 are rotatably matched with the positioning ball 641 and the push ball 651 through the spherical grooves, and the outer end surface of the hinge block 66 is connected to the end of the guide tube 4, and the side wall of the box body 61, the U-shaped seat 64, the hinge block 66 and the end of the guide tube 4 are coaxially provided with a threading hole 67, and a rubber sleeve 68 is arranged in the threading hole 67, the free end of the wire rope 63 passes through the rubber sleeve 68 and extends into the guide tube 4 and is connected to the sliding block 42, and the other side of the sliding block 42 is connected to a spring member 69, and the end of the spring member 69 is connected to the bottom of the other end of the guide tube 4;

[0042] Specifically, when the guide tube 4 swings under the drive of the driving sliding mechanism 7, the end of the guide tube 4 close to the box body 61 will rotate in the U-shaped seat 64 through the cooperation of the hinge block 66, the push ball 651 and the positioning ball 641, so that it will not interfere with the normal swing of the guide tube 4. At this time, the rubber sleeve 68 can be synchronously in a bent state to protect the wire rope 63 to prevent the wire rope 63 from being stuck in the gap between the U-shaped seat 64 and the hinge block 66 when it is in a bent state, thereby affecting the normal winding and releasing of the wire rope 63. When the guide tube 4 stops swinging in the oblique line, the corresponding servo motor inside the box body 61 is controlled to work, so that it winds up the wire rope 63 through the winding drum 62, and the free end of the wire rope 63 will pull the sliding block 42 to slide in the guide tube 4 toward the side of the box body 61. At this time, the spring member 69 will be stretched, and when the wire rope When the rope 63 is released, the sliding block 42 will slide toward the outer end of the guide tube 4 under the elastic recovery of the spring member 69, so as to facilitate the adjustment of the position of the suction cup assembly 3 under the guide tube 4, and realize stable contact and adsorption of irregular plates. Even if the guide tube 4 is located directly below the left and right beams of the frame 2 and is horizontal with the beams, the suction cup assembly 3 can slide along a straight line, so as to adjust the distance between the three suction cup assemblies 3 located on the same straight line, thereby further improving the stability and safety of the contact and adsorption of irregular plates. The threaded rod 65 is threadedly connected to the lower wall of the U-shaped seat 64, and by twisting the threaded rod 65, the push ball 651 can be disengaged from the spherical groove, thereby facilitating the removal of the hinge block 66 from the U-shaped seat 64, making it convenient to remove the guide tube 4, and then facilitating the disassembly and maintenance of the suction cup assembly 3.

[0043] In this embodiment, the driving sliding mechanism 7 includes a screw member 71, and the front and rear side beams of the frame 2 are square tube-shaped, and a through cavity is opened at the bottom thereof. Two screw members 71 are rotatably installed inside the cross beam of the square tube through bearings, and the close ends of the two screw members 71 are supported in the cross beam of the square tube through the support block 5. A guide slider 72 is sleeved on each screw member 71 through a ball nut pair, and the bottom of the guide slider 72 extends out of the through cavity. The bottom of the guide slider 72 is connected to a suspension block 75 through the coordinated rotation of a rotating shaft 73 and a shaft sleeve 74, and an elastic sleeve 76 is installed inside the suspension block 75. The elastic sleeve 76 is slidably sleeved on the guide tube 4, and a limit plug 77 is provided at the outer end of the guide tube 4, and the size of the limit plug 77 is larger than that of the suspension block 75.

[0044] Specifically, when it is necessary to adjust the guide tube 4 to a beveled state, the servo motor fixed at the ends of the front and rear cross beams is controlled to work, so that it drives the correspondingly connected screw member 71 to rotate in the cross beam of the square tube, and drives the guide slider 72 to slide in the cross beam of the square tube through the ball nut, and the bottom of the guide slider 72 is rotatably connected to the suspension block 75. Therefore, the sliding of the guide slider 72 drives the outer end of the guide tube 4 to slide along the lower surface of the front and rear cross beams through the suspension block 75. Since the guide tube 4 is slidably inserted into the elastic sleeve 76 and the length of the guide tube 4 is relatively long, when the guide slider 72 slides toward the middle of the frame 2 in the through cavity, the limit plug 77 will move toward the direction of the suspension block 75. The guide tube 4 can slide horizontally by the suspension block 75, thereby making it easier for the guide tube 4 to swing from the hypotenuse to the state of being parallel to the left and right beams, so that the three suction cup assemblies 3 on the same side are in the same straight line to absorb and de-stacker the regular plates.

[0045] In this embodiment, a support block 5 is provided on the side of the guide tube 4, and a suspension rod 51 is vertically provided on the support block 5. A horizontal bracket 8 is movably installed on the beams on the left and right sides of the frame 2, and a through slide groove 81 is opened on the horizontal bracket 8. The top of the suspension rod 51 extends upward and penetrates the slide groove 81, and a nut 82 is threadedly connected to the outside;

[0046] Specifically, when the guide tube 4 swings in the bevel state, the support block 5 will slide along the length direction of the through slide groove 81 opened on the horizontal bracket 8 through the suspension rod 51. At the same time, the suspension rod 51 will also drive the movably installed horizontal bracket 8 to swing, so that the suspension rod 51 and the horizontal bracket 8 cooperate to suspend and support the middle part of the guide tube 4 that swings in the longest bevel state, to prevent the suction cup assembly 3 from sliding to the middle position of the guide tube 4 to adsorb and load the plate when the guide tube 4 swings in the longest bevel state. Due to the heavy plate being loaded, the middle part of the guide tube 4 is bent, which will affect the safe and normal use of the guide tube 4. The installation position and installation length of the horizontal bracket 8 on the crossbeam need to be adjusted and designed according to the swing trajectory of the support block 5 driven by the guide tube 4, so that it will not interfere with the normal swing adjustment of the guide tube 4 in the bevel state.

[0047] Further defined, the guide tube 4 is made of elastic metal material, threaded rods 65 are fixed on the cross beams on both sides, the horizontal bracket 8 is sleeved on the threaded rod 65, and a nut 82 is threadedly connected to the threaded rod 65, a square sleeve 52 is sleeved on the suspension rod 51, and the square sleeve 52 is located in the through slide groove 81, and a cylinder 32 is fixed on the end of the horizontal bracket 8, and the output rod of the cylinder 32 is connected to the square sleeve 52;

[0048] Specifically, in order to further improve the versatility of the loading equipment for destacking and loading irregular plates, when the guide tube 4 swings into a beveled state, the nut member 82 on the threaded rod 65 is twisted as needed to fix the horizontal bracket 8, and then the output rod of the cylinder member 32 at the end of the horizontal bracket 8 is controlled to extend so that it pushes the square sliding sleeve 52 to slide in the direction away from the cylinder member 32 in the through-slot 81. At this time, the suspension rod 51 will drive the guide tube 4 of the elastic metal material to produce an arc deformation, so that the suction cup assembly 3 can slide along the arc line trajectory, which can further improve the versatility and accuracy of the loading equipment for destacking and loading irregular plates; when the guide tube 4 is required to swing normally into a beveled state or return to a horizontal state, the threaded member 82 on the threaded rod 65 above the crossbeam can be loosened as needed to make the horizontal bracket 8 swing, thereby facilitating the swing and sliding adjustment of the guide tube 4.

[0049] Working principle:

[0050] When the square plates need to be unstackered and loaded, the four guide tubes 4 are all flush with the lower surfaces of the left and right side beams of the frame 2, and then the moving parts of the corresponding guide rail structure on the processing line are controlled to work, so that the lifting parts 1 of the cylinder structure drive the frame 2 to move to the stacked plates, and then the lifting parts 1 drive the frame 2 to move downward, so that the multiple suction cups 33 contact the surface of the plates, and then the air pump controls the multiple air guide hoses 34 to work, so that the multiple suction cups 33 are adsorbed to the surface of the plates, and then the output rods of the multiple cylinder parts 32 on the lower surface of the frame 2 are recovered, so that the plates are first unstackered and separated from the stack, and then the lifting parts 1 and the moving parts work, so that the adsorbed and fixed plates can be transferred to the processing line for subsequent processing;

[0051] When it is necessary to destacker and load irregular plates, if the two right corners of the plates to be destacker and loaded are missing, the two lead screw members 71 on the right side of the frame 2 and symmetrically in front and back can be controlled to rotate, so that the lead screw nut member 82 drives the guide slider 72 to slide toward the middle of the frame 2, and the suspension block 75 drives the sliding sleeve guide tube 4 to slide toward the middle of the frame 2, so that the guide tube 4 swings in a bevel state, and when the guide tube 4 is swinging, the end of the guide tube 4 close to the side of the box 61 will rotate in the U-shaped seat 64 through the cooperation of the hinge block 66, the push ball 651 and the positioning ball 641. When the guide tube 4 stops swinging in the bevel line, the corresponding servo motor inside the box 61 is controlled to work, so that it can pull the wire rope 66 through the winding drum 62 3 is wound up, and the free end of the steel wire rope 63 pulls the sliding block 42 to slide in the guide tube 4 toward the side of the box body 61, at which time the spring member 69 will be stretched, and when the steel wire rope 63 is released, the sliding block 42 will slide toward the outer end of the guide tube 4 under the elastic recovery of the spring member 69, so as to facilitate the adjustment of the positions of the two groups of suction cup assemblies 3 at the bottom right side of the frame 2, and then the adjusted multiple suction cup assemblies 3 are controlled by the lifting component 1 to descend and fit to the upper surface of the irregular plate to adsorb and fix it, and then the output rods of the multiple cylinder members 32 on the lower surface of the frame 2 are recovered, so that it first removes the plate from the stack, and then the lifting component 1 and the moving component work, so that the adsorbed and fixed irregular-shaped plate can be transferred to the processing line for subsequent processing.
