DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the protection scope of the present disclosure.

[0032] Please refer to Figures 1-8The embodiment of the present application provides a kind of full-automatic piece feeding mechanism of middle big density packing board, including conveying table 1, further including disassembly tray protection frame 2, it is located conveying table 1 top, and conveying table 1 is installed with jacking assembly 3 below disassembly tray protection frame 2, lifting assembly 4 is installed in disassembly tray protection frame 2, and lifting assembly 4 bottom both sides are equipped with the lock support component 5 for supporting solidification frame, lifting assembly 4 is also movably installed with the correction member 7 that is transmission connection with lock support component 5, when the second solidification frame located above first solidification frame is locked by lock support component 5, jacking assembly 3 is lowered, so that first solidification frame is separated from jacking assembly 3 and falls to conveying table 1 under the limitation of correction member 7.

[0033] Specifically, conveying table 1 is responsible for stably conveying the solidification frame full of lead-acid battery plate to the disassembly tray station in disassembly tray protection frame 2, jacking assembly 3 can vertically lift the whole solidification frame to separate from conveying table 1, avoid conveying interference, ensure positioning stability, lifting assembly 4 is the core executive component, the built-in lock support component 5 can extend into the interlayer gap of solidification frame, hook the second layer and above frame, when carrying out piece feeding operation, first let the full solidification frame loaded with multiple layers of plates be sent into disassembly tray protection frame 2 from conveying table 1, then jacking assembly 3 is started, the whole solidification frame is lifted to make it separate from the surface of conveying table 1, eliminate vibration interference, then start disassembling layer by layer, lifting assembly 4 is lowered to the preset height, lock support component 5 is accurately inserted between the lowest layer and the second layer of solidification frame, lifting assembly 4 is raised, the second layer and above solidification frame are driven to move upward as a whole by lock support component 5, the lowest single solidification frame is separated and exposed, jacking assembly 3 is lowered, so that the separated solidification frame falls on conveying table 1, the first solidification frame is forced to guide under the action of two correction members 7, realizes vertical zero deviation and falls on conveying table 1, and the cycle is repeated until all levels are disassembled, after the disassembled single solidification frame moves to the outlet end, the plate is accurately grabbed by the mechanical hand, the mechanism is decoupled, the conveying / disassembly / positioning is separated and the timing is cooperatively controlled, replaces manual operation, realizes the full-process automatic piece feeding production of lead-acid battery plate, the forced linkage design of correction member 7 and lock support component 5, in the falling process of first solidification frame, forcedly corrects deviation through physical contact, ensures the landing accuracy, in the stage of repeatedly lifting solidification frame, correction member 7 moves away synchronously with lock support mechanism, avoids interference with the rising solidification frame group, and guarantees the smooth lifting of high-density stack.

[0034] Compared with the prior art, the embodiment of the application drives the lock support assembly 5 to accurately lock the second curing frame above the stack through the lifting assembly 4, uses the linkage correction member 7 to correct the falling position of the first curing frame after the lock support assembly 5 switches the support, and then the lifting assembly 3 below accurately lowers, so that the first curing frame carrying the bottom plate stably separates from the lifting surface under the limitation and guidance of the correction member 7, vertically falls on the conveying table 1, and realizes automatic, accurate and reliable separation of the multi-layer curing frame, ensures that the falling posture of the curing frame on the conveying line is accurate and stable, and at the same time, when the lock support assembly 5 avoids the lifted curing frame, the correction member 7 also moves away, so that the stacked curing frame can be smoothly and stably lifted.

[0035] In a further embodiment of the application, the conveying table 1 is provided with a double-chain conveyor 101, and guide baffles 102 are arranged on both sides of the double-chain conveyor 101. Specifically, after the curing frame is completely positioned, the driving source of the double-chain conveyor 101 is started, and a pair of chains in the double-chain conveyor 101 pushes the curing frame foot forward. Under the continuous constraint of the guide baffles 102, the curing frame translates along a straight line to the next station. The lifting assembly 3 is located between the two chains, and when the lifting assembly 3 is lifted to replace the lock support assembly 5, the bottommost curing frame can be separated from the chains, thereby preventing the chains from interfering with the separation action. The horizontal positioning accuracy of the curing frame in the falling moment and the accuracy in the conveying process are improved compared with the roller conveyor, and the random deviation of the traditional roller conveyor is eliminated.

[0036] In a further embodiment of the application, the lifting assembly 4 includes a double-output motor 401 mounted on the top of the dismounting protection frame 2 and a pair of screw jacks 402.

The bottom of the screw jack 402 is hinged with a lifting frame 404 that is slidingly connected with the inner wall of the dismounting protection frame 2. Specifically, when the double-output motor 401 operates, the double-output shaft outputs torque synchronously, which is transmitted to the two screw jacks 402 through the couplings 403. The rotation of the screw in the screw jack 402 drives the lifting frame 404 to move vertically along the dismounting protection frame 2. When the double-output motor 401 rotates forward, the lifting frame 404 carries the lock support assembly 5 upward. After the second curing frame reaches the corresponding height, the lock support assembly 5 is inserted between the first curing frame and the second curing frame. The lock insertion action triggers and pushes the correction member 7 to move inward, so that the correction members 7 on both sides cooperate to limit the position of the first curing frame to be fallen on the conveying area of the conveying table 1. After the bottom curing frame is conveyed, the double-output motor 401 reverses at low speed, the lifting frame 404 descends, the lock support assembly 5 separates from the upper curing frame, the correction member 7 synchronously retracts, and the lifting assembly 3 rises to replace the carrying, so that the curing frames are continuously separated without manual intervention.

[0037] In a further embodiment of the present application, the lock support assembly 5 comprises a driving motor 501 fixed outside the lifting frame 404 and a shaft rod 502 rotatably installed in the lifting frame 404, the bottom of the shaft rod 502 is fixedly connected with a support rod 503, the output shaft of the driving motor 501 is fixedly connected with a driving gear 504, a pair of transmission tooth rods 505 are slidingly installed outside the lifting frame 404 and are engaged with the driving gear 504, the shaft rod 502 is fixedly connected with a gear ring 506 engaged with the transmission tooth rods 505, specifically, when the driving motor 501 rotates clockwise, the driving gear 504 drives the two transmission tooth rods 505 to slide towards each other, so that the two transmission tooth rods 505 move away from each other and drive the shaft rod 502 to rotate, so that the support rod 503 rotates away from the lifting path of the curing frame, and when the gap between the first curing frame and the second curing frame reaches a suitable height, the driving motor 501 is rotated counterclockwise to reverse the support rod 503 and insert it into the gap, so as to realize the rapid separation of the lowermost curing frame.

[0038] In a further embodiment of the present application, the correction member 7 comprises a limiting support 701 installed inside the lifting frame 404, the top of the limiting support 701 is fixedly connected with a plug-in frame 702 inserted with the lifting frame 404, the output end of the driving motor 501 penetrates the driving gear 504 and is installed with a screw rod 703, the limiting support 701 is provided with a screw hole 704 for the screw rod 703 to threadedly penetrate, specifically, the driving motor 501 is operated to drive the output shaft to synchronously rotate the driving gear 504 and the screw rod 703, the driving gear 504 controls the rotating and lifting action of the lock support assembly 5, and the screw rod 703 drives the horizontal deviation correction position of the correction member 7, the plug-in frame 702 is inserted into the lifting frame 404 to limit the circumferential rotation of the limiting support 701, so that the threaded thrust is converted into pure horizontal movement, when the whole curing frame is lifted by the jacking assembly 3, the driving motor 501 is started to drive the support rod 503 to rotate and extend to be inserted between the first curing frame and the second curing frame, and at the same time, the limiting support 701 is horizontally moved out by rotating the screw rod 703, so that the limiting support 701 on both sides contacts the side surface of the curing frame to forcibly correct the deviation at the moment of falling of the first curing frame, eliminate the deviation caused during the lifting of the curing frame, and enable the separated curing frame to accurately and stably reach the conveying table 1.

[0039] In a further embodiment of the present application, the lifting frame 404 is fixedly connected with sleeve pipes 405 on both sides, the inner wall of the dismounting protection frame 2 is fixedly connected with limiting guide columns 201 penetrating through the sleeve pipes 405, the limiting guide columns 201 are externally sleeved with buffer springs 202, the top end of the buffer spring 202 is connected with the bottom of the sleeve pipe 405, and the bottom end is connected with the table top of the conveying table 1. Specifically, the screw rod elevator 402 drives the lifting frame 404 to move upwards, and the sleeve pipe 405 slides along the limiting guide column 201, the multi-point guiding constraint ensures the parallelism of the lifting frame 404, so that the locking support assembly 5 can stably support the curing frame when the curing frame is completely supported, and the lifting frame 404 can also reduce the buffering force through the buffer spring 202 during the descending process.

[0040] In a further embodiment of the present application, the lifting frame 404 is fixedly connected with sleeve pipes 405 on both sides, the inner wall of the dismounting protection frame 2 is fixedly connected with limiting guide columns 201 penetrating through the sleeve pipes 405, the limiting guide columns 201 are externally sleeved with buffer springs 202, the top end of the buffer spring 202 is connected with the bottom of the sleeve pipe 405, and the bottom end is connected with the table top of the conveying table 1. Specifically, the screw rod elevator 402 drives the lifting frame 404 to move upwards, and the sleeve pipe 405 slides along the limiting guide column 201, the multi-point guiding constraint ensures the parallelism of the lifting frame 404, so that the locking support assembly 5 can stably support the curing frame when the curing frame is completely supported, and the lifting frame 404 can also reduce the buffering force through the buffer spring 202 during the descending process.

[0041] In a further embodiment of the present application, the jacking assembly 3 comprises a base 301 fixed in the conveying table 1, a hydraulic lifting platform 302 is installed on the top of the base 301, a buffer receiving frame 303 is elastically inserted on both sides of the hydraulic lifting platform 302, a receiving groove 304 for embedding the buffer receiving frame 303 is formed on the top surface of the hydraulic lifting platform 302, a top spring 306 connected with the receiving groove is installed in the buffer receiving frame 303, specifically, the hydraulic lifting platform 302 can lift the full layer of curing racks, and can also make the separated bottom layer curing rack fall stably on the conveying table 1, when the hydraulic lifting platform 302 lifts the full layer of curing racks, the buffer receiving frame 303 lifted by the top spring 306 first contacts the bottom of the bottom layer curing rack, then the buffer receiving frame 303 is gradually pressed into the corresponding receiving groove 304, at this time the table surface of the entire hydraulic lifting platform 302 contacts the curing rack, and the stability of lifting is ensured by increasing the contact area, after the bottom layer curing rack is separated alone, the hydraulic lifting platform 302 gradually descends with the curing rack, at this time the buffer receiving frame 303 gradually rises, because the contact area becomes smaller, the correcting part 7 can more quickly correct and fine-tune the position of the separated curing rack, so that the curing rack can be adjusted in position before being conveyed by the double-chain conveyor 101, and the risk of deviation during conveying is reduced.

[0042] In a further embodiment of the present application, the conveying table 1 is fixedly connected with a positioning frame 103, the positioning frame 103 is provided with positioning holes 104 through which the buffer receiving frame 303 passes, specifically, inserting the buffer receiving frame 303 into the positioning hole 104 on the positioning frame 103 can realize the anti-deviation effect of the hydraulic lifting platform 302, so that the hydraulic lifting platform 302 still maintains the vertical movement state after multiple lifting, avoids tilting caused by deviation of the hydraulic lifting platform 302 during the lifting of the multiple curing racks, reduces the wear of each positioning and correcting structure, and prolongs the service life of the equipment.

[0043] In a further embodiment of the present application, the brake frame 105 is movably mounted outside the conveying table 1, the wedge-shaped insertion rod 106 is symmetrically and elastically mounted at one end of the brake frame 105, the brake frame 105 is connected with the limiting support 701, and the one-way non-return rack 305 is embedded outside the buffer receiving frame 303. When the limiting support 701 moves inward with the brake frame 105, the wedge-shaped insertion rod 106 abuts against the one-way non-return rack 305. Specifically, when the limiting support 701 moves inward, it means that the supporting rod 503 in the lock supporting assembly 5 has been turned out. During the inward movement of the limiting support, the brake frame 105 moves together, and the wedge-shaped insertion rod 106 is inserted into the one-way non-return rack 305. When the supporting rod 503 is turned out, the hydraulic lifting table 302 cannot continuously rise under the pulling of the buffer receiving frame 303, thereby avoiding damage to the lock supporting assembly 5 caused by the hydraulic lifting table 302 or the multiple curing frames above it. However, when the hydraulic lifting table 302 descends with the curing frames, even if the wedge-shaped insertion rod 106 abuts against the one-way non-return rack 305, it can move back under the action of the elastic force, without affecting the normal separation and conveying of the curing frames, thereby reducing the risk of equipment operation.

[0044] The foregoing merely describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the foregoing drawings and descriptions are illustrative in nature, and should not be construed as limiting the scope of protection of the claims of the present application.
