Description

Technical Field

[0001] This utility model relates to the field of sheet metal production equipment technology, and in particular to a sheet metal production line palletizing adjustment device. Background Technology

[0002] The board production line palletizing and adjusting device is an automated equipment installed at the end of the board production line. Its core function is to realize the automatic conversion and precise positioning of boards from continuous production to orderly stacking. This device mainly uses adsorption and handling equipment to move and transport boards, combined with sensors to detect the size and position of the boards, and uses a programmable controller to drive the mechanical actuator to dynamically adjust the stacking posture and interlayer spacing of each layer of boards, ensuring that the stack is neat and stable. It effectively connects the production and warehousing links, greatly improves palletizing efficiency and quality, and is a key piece of equipment for achieving efficient logistics in modern board production.

[0003] However, the existing board production line palletizing adjustment devices can only handle boards of fixed width. When changing boards of different sizes, a lot of manual mechanical adjustments are required, which is inefficient. Furthermore, during continuous palletizing, the impact force or slight positional deviation of the upper board when it is put down will hit the lower board that has already been placed, causing the cumulative error to become larger and larger, and the whole stack of boards becomes skewed and unstable.

[0004] Therefore, we propose a stacking adjustment device for sheet metal production lines to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sheet metal palletizing and adjusting device includes two gantry supports, an adsorption platform, and a centering platform. A feeding conveyor belt and a discharging conveyor belt are placed inside the inner space of the two gantry supports. The discharging conveyor belt is connected to the centering platform. A common guide rail is fixedly installed on the top of the two gantry supports. A sliding table is slidably fitted onto the bottom of the guide rail. Four lifting sleeves are fixedly installed on the bottom of the sliding table. Lifting shafts are slidably installed on the inner side of each of the four lifting sleeves. The adsorption platform is fixedly installed at the bottom end of the four lifting shafts. Two adsorption bases are slidably installed on the bottom of the adsorption platform, and the two adsorption bases are mutually... Position sensors are fixedly installed on the opposite side of each adsorption platform. Multiple evenly distributed industrial suction cups are fixedly installed on the bottom of each of the two adsorption bases. A protective shell is fixedly installed on the top of the adsorption platform. A push cylinder is fixedly installed on the top of the centering platform. A centering chamber is opened on the inner side of the centering platform. A lifting platform is slidably installed on the inner side of the centering chamber. Four centering sliders are slidably installed on the top of the lifting platform. An adjusting base is fixedly installed on the top of each of the four centering sliders. An adjusting groove is opened on one side of each of the four adjusting bases. A centering metal strip is slidably installed on the inner side of each of the four adjusting grooves.

[0007] Specifically, a ball screw is rotatably mounted on the inner wall of one side of the guide rail, and the slide is threaded onto the ball screw. A guide rail servo motor is fixedly mounted on one side of the guide rail, and the output shaft of the guide rail servo motor is fixedly connected to the ball screw. The ball screw transmission method has the characteristics of high precision and high efficiency, which can ensure that the slide moves smoothly and accurately on the guide rail. In conjunction with the guide rail servo motor, the slide can achieve precise positioning in the horizontal direction, meeting the palletizing requirements of different workstations.

[0008] Specifically, lifting hydraulic cylinders are fixedly installed on the top inner walls of the four lifting sleeves. The parameters of the four lifting hydraulic cylinders are the same, and the hydraulic rods of the four lifting hydraulic cylinders are fixedly connected to the top of the corresponding lifting shaft. The lifting hydraulic cylinders can provide strong thrust to ensure that the adsorption platform remains stable during the lifting process, and can operate stably even when bearing heavy plates.

[0009] Specifically, a vacuum base is fixedly installed at the bottom of the slide, a vacuum pump is fixedly installed on the inner side of the vacuum base, a flow divider is fixedly installed on the pumping end of the vacuum pump, and telescopic hoses are fixedly installed on both output ends of the flow divider. The telescopic hoses have good flexibility and extensibility and will not be pulled or twisted due to the movement of the adsorption platform, thus ensuring the stability of the vacuum extraction process.

[0010] Specifically, a linkage disc is rotatably mounted on the inner side of the protective shell. Two symmetrically distributed linkage ports are opened on the top of the linkage disc. An adjusting worm gear is fixedly sleeved on the outer side of the linkage disc. A linkage sleeve is fixedly connected to one side of the protective shell. A dust-blocking mesh is fixedly mounted at one end of the linkage sleeve. An adjusting servo motor is fixedly mounted on the inner side of the linkage sleeve. An adjusting worm is rotatably mounted on the inner wall of one side of the linkage sleeve. The adjusting worm meshes with the adjusting worm wheel. The output shaft of the adjusting servo motor is fixedly connected to the adjusting worm. The combination of the adjusting worm and the adjusting worm wheel has a self-locking function, ensuring that the position is fixed after adjusting the spacing of the adsorption base and will not change due to external forces.

[0011] Specifically, the top of the adsorption platform has two symmetrically distributed guide ports. A linkage shaft is slidably installed on the inner side of each guide port. The top ends of the two linkage shafts are slidably installed on the inner side of their respective linkage ports. The bottom ends of the two linkage shafts are fixedly connected to their respective adsorption bases. Adsorption chambers are formed inside each of the two adsorption bases. The bottom ends of two telescopic hoses are fixedly inserted through their respective linkage shafts and extend into their respective adsorption chambers. The top ends of multiple industrial suction cups extend into their respective adsorption chambers. The adsorption chambers serve as a transfer space for negative pressure transmission, evenly distributing the negative pressure delivered by the telescopic hoses to each industrial suction cup, ensuring that each industrial suction cup can effectively adsorb the board material.

[0012] Specifically, each of the four centering sliders has two inclined openings on one side. The two inclined openings on the same centering slider are at different heights. The same linkage metal strip is slidably installed on the inner side of two adjacent inclined openings of the same height. An electric push rod is fixedly installed on the top of the lifting platform. The output shaft of the electric push rod is fixedly connected to one side of the corresponding centering slider. An adjusting hydraulic cylinder is fixedly installed on the inner wall of one side of each of the four adjusting slots. The hydraulic rods of the four adjusting hydraulic cylinders are fixedly connected to the corresponding centering metal strips. The cooperation between the inclined openings and the linkage metal strips realizes the linkage of the four centering sliders. When one centering slider is pushed by the electric push rod, the linkage metal strips can drive the other centering sliders to move synchronously, ensuring the consistency of the centering action.

[0013] Specifically, four evenly distributed lifting cylinders are fixedly installed on the bottom inner wall of the centering chamber. The four lifting cylinders have the same parameters, and the piston ends of the four lifting cylinders are fixedly connected to the bottom of the same lifting platform. The top of the centering platform has four centering openings, which are connected to the same centering chamber. Four centering metal strips are slidably installed on the inner side of the corresponding centering openings. The design of the centering openings allows the centering metal strips to extend out of the centering chamber to position and correct the plate. After the positioning and correction are completed, they can be retracted without affecting the entry and exit of the plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] (1) The plate stacking adjustment device of this utility model can drive two adsorption bases to move closer or further apart by setting an adjustment servo motor, adjustment worm gear, adjustment worm, linkage disk and linkage shaft. Combined with position sensor, it can automatically identify and align the edge of the plate, and realize the adaptive adjustment of the adsorption structure to plates of different widths.

After the positioning and correction are completed, they can be retracted without affecting the entry and exit of the plate.

[0032] Working Principle: When stacking and arranging boards, the operator first starts the equipment. The feeding conveyor belt moves the boards to directly below the adsorption platform 13. Then, the adjusting servo motor 17 is started, which drives the adjusting worm gear 18 to rotate, which in turn drives the adjusting worm wheel 19 to rotate. The rotation of the adjusting worm wheel 19 drives the linkage disk 20 to rotate. The top of the linkage disk 20 has two linkage ports, and the inner side of each linkage port is slidably installed with a linkage shaft 21. The two linkage shafts 21 move radially along their corresponding guide ports. The two linkage shafts 21 move closer or further away from each other, which drives the corresponding adsorption base 22 to move. The two adsorption bases 22 drive the corresponding multiple industrial suction cups 23 to move closer or further away from each other. When the position sensor 24, fixedly installed on the side of the two suction bases 22 that are far apart from each other, is aligned with the edge of the board, the servo motor 17 is turned off, completing the adjustment of the position of the two suction bases 22. At this time, the operator starts the four lifting hydraulic cylinders 7, which drive the corresponding lifting shafts 8 to move downwards, thereby causing the multiple industrial suction cups 23 to come into contact with the surface of the board. At this time, the vacuum pump 10 is started, generating negative pressure. The negative pressure is evenly distributed through the diverter head 11 and enters the two telescopic hoses 12. Subsequently, the negative pressure enters the interior of the corresponding suction base 22 through the two telescopic hoses 12, thereby removing the air between the multiple industrial suction cups 23 and the surface of the board, so that the board is firmly adsorbed onto the multiple industrial suction cups 23. At this point, the operator controls the four lifting hydraulic cylinders 7 to reset and starts the guide rail servo motor 3. The guide rail servo motor 3 drives the ball screw 4 to rotate, which in turn drives the slide table 5 to move axially along the ball screw 4. When the slide table 5 moves the adsorption platform 13 along with the plate to directly above the centering platform 25, the four lifting hydraulic cylinders 7 drive the adsorption platform 13 along with the plate to move down. When the plate moves down and contacts the pallet placed on top of the centering platform 25, the vacuum pump 10 is turned off. At this time, the suction force of the multiple industrial suction cups 23 is greatly weakened, and the plate detaches from the multiple industrial suction cups 23 by its own gravity. Then, the slide table 5 and the adsorption platform 13 are driven to reset, completing the displacement and placement of the plate. To ensure that the plate is in the center of the pallet, the operator starts... Four lifting cylinders 28 drive the same lifting platform 27 to move stably upwards. The upward movement of the lifting platform 27 causes the components on it to move upwards. At this time, the four centering metal bars 34 rise, and their tops are higher than the top of the centering platform 25. Then, the electric push rod 31 is activated, which drives the corresponding centering slider 29 to move. The displacement of the centering slider 29 driven by the electric push rod 31 causes the two sliding linkage metal bars 30 on it to move. The displacement of the two linkage metal bars 30 respectively causes the two centering sliders 29 adjacent to the centering slider 29 driven by the electric push rod 31 to move. The two centering sliders 29 respectively drive the same centering slider 29 to move through the corresponding linkage metal bars 30. At this time, the four centering sliders 29 move synchronously.The four centering sliders 29 move, causing their corresponding centering metal strips 34 to move closer together, thus approaching the sheet material. Then, based on the sheet material's size, the operator activates four adjusting hydraulic cylinders 33. These cylinders adjust the position of the corresponding centering metal strips 34 to accommodate different sheet material sizes, ensuring they contact the sheet material's edge, completing the initial centering adjustment. Subsequently, during sheet material stacking, the electric push rod 31 drives the four centering sliders 29 closer together to center the sheet material, preventing displacement during stacking. After the sheets are stacked, the operator controls the lifting platform 27 to move downwards, aligning the tops of the four centering metal strips 34 with the top of the centering platform 25. Then, the cylinder 26 is activated to move the stacking tray and sheet material, which are then moved onto the discharge conveyor belt for subsequent processes.

[0033] The technological advancements of this invention compared to existing technologies are as follows: it can drive two adsorption bases 22 to move closer or further apart from each other, and combined with the position sensor 24, it can automatically identify and align the edges of the boards, enabling the adsorption structure to adaptively adjust to boards of different widths. Furthermore, before or after placing each new layer of boards, the electric push rod 31 can be activated to allow the four centering metal strips 34 to gently clamp the entire stack of boards, correcting and straightening them, thereby ensuring the neatness and stability of the entire stacking process.
