Description

Technical Field

[0001] This invention relates to the field of sheet material conveying equipment, specifically an automatic sheet material feeding and unloading machine. Background Technology

[0002] As the core equipment of the surface mount technology production line, the unloading machine undertakes the key functions of automated board collection and material management. Its core function is to receive signals from upstream equipment (such as pick-and-place machines and reflow ovens) and accurately collect boards into the material rack or designated workstation, realizing the stacking and storage of boards and significantly saving storage space.

[0003] For example, a pallet stacking loading and unloading machine with publication number CN223254033U includes a gantry frame.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-3 and Figures 9-11The automatic board feeding and unloading machine of this embodiment includes a frame 1. A board feeding section 2 is arranged in the middle of the frame 1. A feeding section 3 and an unloading section 4 are symmetrically arranged on both sides of the board feeding section 2. A film inlet 5 is arranged in the middle of the side of the board feeding section 2. A board inlet 6 is arranged on the side of the feeding section 3 away from the board feeding section 2. A board outlet 7 is arranged on the side of the unloading section 4 away from the board feeding section 2. A film feeding mechanism 8 is horizontally arranged inside the board feeding section 2 facing the film inlet 5 for feeding the film. The film feeding mechanism 8 has a horizontally arranged material box discharge flow line 9 on the side away from the film inlet 5, used to transport the material boxes during plate feeding. A plate picking mechanism 18 is arranged on the side of the material box discharge flow line 9 away from the film feeding mechanism 8, used to remove the plate from the material box. A pair of material box picking and placing mechanisms 10 are symmetrically arranged on both sides of the material box discharge flow line 9, used to pick up and place the material boxes. A pair of material tray picking and placing mechanisms 11 are symmetrically arranged on both sides of the material tray picking mechanism 18, used to pick up and place the material trays. A pair of second translation mechanisms 14 are symmetrically arranged on the top of the box feeding flow line 9 and the board picking mechanism 18. A film handling mechanism 15 and a board handling mechanism 16 are respectively arranged between the moving platforms of the pair of second translation mechanisms 14 for alternating stacking of boards and films. The board picking mechanism 18 includes several support bases 1801. A tray feeding flow line 1802 is horizontally arranged on the top of the support bases 1801, and several lifting mechanisms are vertically arranged at the bottom of the tray feeding flow line 1802. The lifting mechanism 1804 has a lifting platform fixedly connected to a top plate 1807, and a number of ejector pins 1808 are vertically arranged on the top of the top plate 1807; a flipping mechanism 1805 is horizontally arranged on the top edge of the support base 1801, and a cover plate 1806 is fixedly connected to the rotating platform of the flipping mechanism 1805; a number of third locking cylinders 1803 are vertically fixedly connected at the top corner of the support base 1801; and a number of fourth locking cylinders 22 are symmetrically arranged on both sides of the middle of the material box discharge flow line 9.When the sheet material is unloaded, the film is loaded by the film loading mechanism 8, and then the empty material box is transported to the unloading station in the middle of the material box unloading flow line 9 by the material box picking and placing mechanism 10 of the loading section 3. The material box is positioned and fixed by the fourth locking cylinder 22 on both sides of the material box unloading flow line 9. Then, the full-loaded sheet material is transported to the material box unloading flow line 1802 by the material tray picking and placing mechanism 11. At this time, the material tray is positioned and fixed by the third locking cylinder 1803 at the four corners of the top of the support base 1801. Then, the cover plate 1806 is driven by the flipping mechanism 1805 to fasten to the top of the material tray, and then the top... The lifting mechanism 1804 drives the top plate 1807 to move upward until the ejector pin 1808 at the top of the top plate 1807 inserts into the corresponding bottom hole at the bottom of the tray, thereby lifting the board at the top of the tray for easy loading and unloading. At this time, the film conveying mechanism 15 places the film on the film loading mechanism 8 into the inside of the box. Then, the board conveying mechanism 16 stacks the boards in the tray on top of the film in the box. The above steps are repeated to prevent the stacking of film and board, thereby isolating and protecting adjacent boards with film and avoiding contact between boards that could cause damage.

[0036] Please see Figure 4 The film loading mechanism 8 includes a first mounting frame 801. A first lifting mechanism 802 is provided on the side of the first mounting frame 801. A lifting plate 803 is horizontally fixedly connected to the lifting platform of the first lifting mechanism 802. A plurality of through grooves 805 are opened on the surface of the lifting plate 803. A plurality of slide rails 804 are horizontally provided at the bottom of the first mounting frame 801. A plurality of sliding frames 806 are slidably connected to the top of the slide rails 804. A plurality of guide rods 807 are vertically fixedly connected to the top of the sliding frames 806. The top of the guide rods 807 passes through the through grooves 805 and is slidably connected to them. When loading film, the film is placed on top of the lifting plate 803 through the film inlet 5. Before placement, the position of the sliding frame 806 on the slide rail 804 can be adjusted according to the size of the film. When the sliding frame 806 moves, it drives the guide rod 807 on its top to move accordingly until the distance between adjacent sliding frames 806 matches the size of the film. Then, the lifting plate 803 is driven to move upward to the lower plate station through the first lifting mechanism 802 to realize automatic loading of film.

[0037] Please see Figure 5The material box picking and placing mechanism 10 includes a second mounting frame 1001. A second lifting mechanism 1002 is provided on the inner side wall of the second mounting frame 1001. A material box conveying flow line 1003 is horizontally arranged on the lifting platform of the second lifting mechanism 1002. Several first locking cylinders 1004 are horizontally arranged at the corners of the lifting platform of the second lifting mechanism 1002. A material box conveying cart 12 is provided on the side of the second mounting frame 1001 away from the plate section 2. A material box is detachably and slidably mounted on the top of the material box conveying cart 12. A transition flow line 1005 is horizontally arranged between the material box conveying cart 12 and the opposing side wall of the second mounting frame 1001. When loading the material boxes, the material box conveyor 12 carrying empty material boxes is first connected to the material box loading and unloading mechanism 10. Then, the material box conveying flow line 1003 is driven by the second lifting mechanism 1002 to move to a height that matches the transition flow line 1005. At this time, the material box on the top of the material box conveyor 12 is pushed, so that the material box moves along the transition flow line 1005 to the top of the material box conveying flow line 1003. At this time, the material box is fixed by the first locking cylinder 1004. Then, the material box conveying flow line 1003 is driven by the second lifting mechanism 1002 to move to a height that matches the material box unloading flow line 9. At this time, the first locking cylinder 1004 is reset, and the material box is conveyed to the material box unloading flow line 9 through the material box conveying flow line 1003. When the material box is fully loaded for unloading, the above steps are repeated in reverse to realize automatic loading and unloading of the material boxes.

[0038] Please see Figures 6-7The material tray loading and unloading mechanism 11 includes a third mounting frame 1101 and a third lifting mechanism 1102 disposed on its inner side wall. A first translation mechanism 1104 is disposed between the lifting platforms of the third lifting mechanism 1102. A material tray conveying flow line 1105 is horizontally disposed on the moving platform of the first translation mechanism 1104. A material tray conveying trolley 13 is disposed on the side of the third mounting frame 1101 away from the plate placement section 2. A material tray height sensor 1103 is disposed between the material tray conveying trolley 13 and the edge of the third mounting frame 1101. When loading the pallets, the pallet conveyor 13, carrying multiple full pallets, is connected to the bottom of the third mounting frame 1101. At this time, the first translation mechanism 1104 moves to the bottom of the third mounting frame 1101 along with the third lifting mechanism 1102. Then, the first translation mechanism 1104 drives the top pallet conveyor line 1105 to extend into the bottom of the pallet conveyor 13. The third lifting mechanism 1102 then drives the pallet conveyor line 1105 upwards, lifting the bottommost pallet of the pallet conveyor 13, causing it to detach from the pallet conveyor 13. Then, the first translation mechanism 1104 drives the pallet conveyor line 1105 to reset, and the third lifting mechanism 1102... The drive tray conveyor 1105 moves to a height matching the tray unloading conveyor 1802. At this point, the tray is conveyed to the tray unloading conveyor 1802 via the tray conveyor 1105. During conveying, the tray flows through the dust collection chamber at the top of the tray conveyor 1105, thereby cleaning the board material on top of the tray. When the tray finishes unloading, the above steps are repeated in reverse to achieve automatic loading and unloading of the tray, effectively improving the unloading efficiency of the board material. By setting a tray height sensor 1103, the height of the tray in the tray conveyor 13 can be sensed, thereby guiding the lifting and lowering of the tray conveyor 1105 and avoiding collisions with the tray.

[0039] Please see Figure 8 The bottom of the second mounting frame 1001 and the third mounting frame 1101, on the side wall away from the plate-laying section 2, are both provided with docking mechanisms 21.

A buckle plate 2103 is hinged to the piston rod of the docking cylinder 2102. The buckle plate 2103 and the base 2101 are rotatably connected through a connecting shaft 2104. When the material box conveyor 12 and the material tray conveyor 13 are docked, the buckle plate 2103 is inserted into the docking hole at the corresponding position, and then the buckle plate 2103, which is hinged to it, is driven by the docking cylinder 2102 to rotate downward around the connecting shaft 2104, thereby buckling the material box conveyor 12 and the material tray conveyor 13.

[0040] Please see Figures 12-13 The film transport mechanism 15 includes a third translation mechanism 1501. Several moving platforms of the third translation mechanism 1501 are vertically fixedly connected to a fourth lifting mechanism 1502. The lifting platform of the fourth lifting mechanism 1502 is fixedly connected to a first rotary cylinder 1503. The rotating platform of the first rotary cylinder 1503 is fixedly connected to several film suction cups 1504. The sheet material transport mechanism 16 includes a fourth translation mechanism 1601 and several fifth lifting mechanisms 1602. The fifth lifting mechanisms 1602 are vertically fixedly connected to several moving platforms of the fourth translation mechanism 1601. The lifting platform of each fifth lifting mechanism 1602 is fixedly connected to a second rotary cylinder 1603. The rotating platform of the second rotary cylinder 1603 is fixedly connected to several sheet material suction cups 1604. The side walls of the fourth lifting mechanism 1502 and the fifth lifting mechanism 1602 are equipped with distance sensors 24. During film handling, the film suction cup 1504 at the bottom of the fourth lifting mechanism 1502 is moved to the top of the film at the corresponding position by the third translation mechanism 1501. Then, the film suction cup 1504 is moved downward by the fourth lifting mechanism 1502 until it contacts the film. At this time, the fourth lifting mechanism 1502 resets and drives the film suction cup 1504 to pick up the film. Then, the film suction cup 1504 is moved to the top of the material box by the second translation mechanism 14. During the movement, the placement angle and direction of the film can be adjusted by the first rotary cylinder 1503. Then, the film suction cup 1504 is placed into the material box by the fourth lifting mechanism 1502. The above steps are repeated, and the plate handling mechanism 16 stacks the plates on top of the film to achieve alternating stacking of film and plates. During placement, the distance sensor 24 can guide the picking and placement position of the film and plates.

[0041] A camera detection mechanism 17 is installed on the top of the film transport mechanism 15 and the sheet transport mechanism 16. The camera detection mechanism 17 includes a pair of fifth translation mechanisms 1701. A sixth translation mechanism 1702 is arranged between the moving platforms of the pair of fifth translation mechanisms 1701. A sixth lifting mechanism 1703 is fixedly connected to the moving platform of the sixth translation mechanism 1702. A camera 1704 is vertically fixedly connected to the lifting platform of the sixth lifting mechanism 1703. When the sheet is ejected from the material tray in the material tray discharge flow line 1802, the ejection status of the sheet can be detected and judged by the camera. The position and height of the camera can be adjusted by the fifth translation mechanism 1701, the sixth translation mechanism 1702, and the sixth lifting mechanism 1703 to improve the detection accuracy.

[0042] A recycling mechanism 19 is provided on the side of the sheet material receiving mechanism 18 away from the material box discharge flow line 9. The recycling mechanism 19 includes a film waste cart 1903. A seventh translation mechanism 1901 is provided on the outer side of the top of the film waste cart 1903. The moving platform of the seventh translation mechanism 1901 is detachably provided with a sheet material collection trough 1902. An eighth translation mechanism 23 is provided on the other side of the top of the film waste cart 1903. The moving platform of the eighth translation mechanism 23 is fixedly and detachably provided with a sample detection trough 25. During the board placement process, when a defective board is detected, the board handling mechanism 16 places the corresponding defective board into the board collection trough 1902, and then the seventh translation mechanism 1901 pushes the defective board out for recycling. When film damage is detected, the film handling mechanism 15 can place the waste material into the film waste cart 1903 for recycling. When board testing is required, the board handling mechanism 16 places the board sample into the sample testing trough 25, and the eighth translation mechanism 23 pushes the sample out for testing, thus realizing automatic testing of board samples.

[0043] Working principle: When the board is unloaded, the film is fed by the film feeding mechanism 8. During film feeding, the film is placed on the top of the lifting plate 803 through the film inlet 5. Before placement, the position of the sliding frame 806 on the slide rail 804 can be adjusted according to the size of the film. When the sliding frame 806 moves, it drives the guide rod 807 at its top to move accordingly until the distance between adjacent sliding frames 806 matches the size of the film. Then, the first lifting mechanism 802 drives the lifting plate 803 to move upward to the unloading station, realizing automatic feeding of the film. Then, the empty material box is transported to the unloading station in the middle of the material box unloading flow line 9 by the material box picking and placing mechanism 10 of the feeding section 3. The material box is positioned and fixed by the fourth locking cylinder 22 on both sides of the material box unloading flow line 9. Then, the material plate fully loaded with board is transported to the material tray picking and placing mechanism 11. In the material feeding flow line 1802, the material tray is positioned and fixed by the third locking cylinder 1803 at the four corners of the top of the support base 1801. Then, the cover plate 1806 is driven by the flipping mechanism 1805 to fasten to the top of the material tray. Then, the top plate 1807 is driven to move upward by the lifting mechanism 1804 until the pin 1808 on the top of the top plate 1807 is inserted into the corresponding bottom hole at the bottom of the material tray, thereby lifting the material on the top of the material tray for easy loading and unloading. At this time, the film conveying mechanism 15 places the film on the film feeding mechanism 8 into the inside of the material box. Then, the material conveying mechanism 16 stacks the material in the material tray on top of the film in the material box. The above steps are repeated to prevent the stacking of film and material, thereby isolating and protecting adjacent material with film and avoiding contact between material and damage to the material.
