Its core function is to stack and place battery parts in an orderly manner and transfer them between different workstations. The device usually includes a stacking mechanism, which can achieve layer-by-layer stacking of parts through components such as robotic arms and conveyor belts to ensure neat and stable stacking; the transportation part may use rails, AGVs, etc., so that the stacked parts can be moved in production lines, warehouses and other scenarios. It may also be equipped with a control system to adjust parameters such as stacking height and transportation speed to ensure operational efficiency. This type of equipment can reduce manual handling and improve the degree of automation in the storage and transportation of battery parts. It is commonly found in battery production or warehousing, helping to optimize the production process.

[0003] The prior art announcement number is CN116239057B, and discloses a heavy-duty stacker for intelligent storage and transportation of battery production lines.

DETAILED DESCRIPTION

[0031] It is easy to understand that, according to the technical solution of the present application, one of ordinary skill in the art can propose a plurality of structural modes and implementation modes that can be replaced with each other without changing the essential spirit of the present application. Therefore, the following detailed description and the accompanying drawings are only exemplary descriptions of the technical solution of the present application, and should not be considered as the whole or as a limitation or restriction on the technical solution of the present application.

[0032] REFERENCE Figure 1 As shown in the drawings, the present application provides a technical solution: a battery accessory stacking and transporting machine, comprising a column assembly 1, a top of the column assembly 1 horizontally supporting an overhead rail assembly 2, a bottom of the column assembly 1 and parallel to the overhead rail assembly 2 supporting a ground rail assembly 3, and a load-bearing platform assembly 4 movably installed on one side of the column assembly 1 and suspended between the overhead rail assembly 2 and the ground rail assembly 3.

[0033] REFERENCE Figure 1-Figure 2As shown, in the present embodiment: the column assembly 1 as the main support structure of the battery accessory stacking conveyor, including a column 11, which adopts a rectangular hollow section steel as the main body, and a low-alloy high-strength structural steel is selected as the material. The hollow structure of the column 11 is provided with stiffening plates 12 at equal intervals inside. When the hollow column 11 is subjected to external forces, such as lateral forces when the loading platform is lifted, and vibration when the equipment is running, local buckling deformation is prone to occur. The stiffening plates 12 separate the hollow section and limit the deformation of the wall surface of the column 11, so that the column 11 is more stable when bearing vertical and horizontal loads, and the deformation of the column 11 caused by the shaking of the stacking machine during operation is reduced. At the same time, when the column 11 transmits the pressure of the top overhead rail assembly 2 and its own bearing load, the stiffening plates 12 can disperse the stress from the wall surface of the column 11 to themselves, avoiding stress concentration in the local position of the column 11, preventing the column 11 from cracking or deforming due to excessive stress, and prolonging the service life of the column 11.

[0034] A maintenance ladder 13 is bolted to the wall of the non-drive side of the column 11, which is made of hot-dipped galvanized steel grating material and is segmented and spliced on the surface of the column 11, facilitating transportation and on-site installation.

[0035] A steel wire drum 14 and a lifting motor 15 are integrated and installed on one side of the column 11 to form a vertical lifting drive system. The mounting surface of the steel wire drum 14 and the mounting surface of the maintenance ladder 13 are orthogonally arranged, i.e., the planes where they are located are perpendicular to each other, avoiding installation interference and operation conflict between functional components, effectively ensuring the transmission stability of the lifting mechanism, while taking into account the portability of the maintenance space; the steel wire drum 14 selects a new roller bearing, which is supported by double bearing seats welded and installed on both sides of the mounting surface of the column 11. The center distance is adjusted according to the length of the drum shaft. Vibration damping rubber pads can be optimally added between the bearing seat and the column 11 to reduce operating noise. The surface of the steel wire drum 14 can be optimally machined with a spiral rope groove to ensure the orderly winding of the steel wire rope and prevent random winding; the lifting motor 15 is bolted to the top surface of the steel wire drum 14. The output shaft of the lifting motor 15 is connected to the winding shaft of the steel wire drum 14 by a coupling. A protective cover is installed on the outside of the coupling to prevent foreign objects from being sucked in and ensure the safety of the operation.

[0036] An electric control box 16 is welded and installed on the wall of the column 11 and vertically below the steel wire drum 14. The installation height is 1.5 m from the ground, facilitating electrical debugging and maintenance by operators.

[0037] Referring to Figure 1-Figure 3As shown in the embodiment: the overhead rail assembly 2 as the upper guide and power transmission structure of the horizontal movement of the stacker, including the overhead rail 21, the overhead rail 21 is fixed with the steel structure beam of the factory building top by welding, using L-shaped hot-rolled section steel, the material is low alloy high strength steel, extending horizontally along the stacker operation area, the overhead guide wheel 22 is movably installed on the horizontal flange of the L-shaped rail, the surface of the rail is quenched to improve wear resistance; the overhead guide wheel 22 contains four double-row roller bearings, the surface of the wheel is sprayed with wear-resistant rubber layer, the overhead guide wheel 22 is fixed on the top surface of the column 11 through the welded base, forming a rigid connection, the axis of the overhead guide wheel 22 is perpendicular to the horizontal flange of the overhead rail 21, ensuring smooth running.

[0038] The overhead guide wheel 22 is movably installed on the horizontal flange of the overhead rail 21, the overhead guide wheel 22 contains four double-row roller bearings, the surface of the wheel is sprayed with wear-resistant rubber layer, the overhead guide wheel 22 is fixed on the top surface of the column 11 through the welded base, forming a rigid connection, the axis of the overhead guide wheel 22 is perpendicular to the horizontal flange of the overhead rail 21, ensuring smooth running.

[0039] Referring to Figures 1-4 As shown in the embodiment: the ground rail assembly 3 as the bottom support and drive structure of the horizontal movement of the stacker conveyor, including the ground rail 31, the ground rail 31 adopts swallow-tail hot-rolled steel rail, the surface is quenched to improve wear resistance and impact resistance, the ground rail 31 is embedded in the reinforced concrete foundation at the bottom, fixed with the rail through the anchor bolt, ensuring the stability of the stacker conveyor during transportation.

[0040] The ground rail 31 is installed with the ground rail beam 32 above, the ground rail beam 32 adopts rectangular hollow section steel as the main body, with partitions inside to enhance rigidity, avoiding deformation or distortion of the ground rail beam 32 under the action of heavy objects, two groups of ground rail running wheels 33 are installed at the bottom of the front and rear sides of the ground rail beam 32 along the driving direction, the ground rail running wheels 33 are closely fitted with the recessed wing surface on both sides of the swallow-tail ground rail 31, providing precise guidance and stable support for the movement of the stacker conveyor, the wheel body surface is sprayed with wear-resistant ceramic coating to improve wear resistance and prolong the service life of the ground rail running wheels 33.

[0041] The front and rear ends of the ground rail beam 32 along the driving direction of the stacker conveyor are installed with infrared sensors 35 through bolts, which are used to detect obstacles in front and rear, avoiding collision accidents; the front moving motor 34 is installed above the side close to the column assembly 1 of the ground rail 31, the front moving motor 34 is the power core of driving the horizontal movement of the stacker conveyor, the output shaft is installed with a helical gear, the power is efficiently transmitted to the ground rail running wheels 33 through chain transmission, realizing the linear movement of the stacker along the rail.

[0042] Referring to Figures 5-10 As shown, in this embodiment: the load-bearing platform assembly 4 serves as the core execution unit of the battery accessories stacking and conveying machine, and is responsible for the cargo carrying, alternating transfer and storage and retrieval functions, including a bottom plate component 41, two alternating platform components 42 are installed above the bottom plate component 41, and a fork component 43 is installed between the two alternating platform components 42.

[0043] The base plate component 41 serves as the basic supporting structure of the load-bearing platform assembly 4, including a base plate 411. The base plate 411 is made of L-shaped high-strength alloy steel plate and is welded by a vertical axial protrusion and a horizontal axial protrusion. The vertical surface of the base plate 411 is connected to the column 11 to realize lifting and lowering guidance, and the horizontal surface provides an installation reference for the alternating platform component 42 and the fork component 43.

[0044] The top surface of the vertical axis protrusion of the base plate 411 is symmetrically installed with a wire pulley 412 through bolts. The pulley is supported by a deep groove ball bearing. The wheel groove radius is adapted to the lifting wire rope. A lubrication hole is provided at the bottom of the groove to ensure smooth guidance of the wire rope. The wire rope is retracted and released through the wire drum 14 to realize the vertical lifting drive of the support platform assembly 4.

[0045] A groove is provided on the connecting surface between the bottom plate 411 and the column 11, and two sets of limiting pulleys 413 are installed on the inner wall surfaces on both sides of the groove in an upper and lower distribution. The pulleys fit tightly with the side guide rails of the column 11 to form a rolling guide to ensure that the supporting platform assembly 4 moves vertically along the column 11 when lifting and lowering to prevent lateral deviation.

[0046] A support frame 414 is installed on the bottom surface of the horizontal axial protrusion of the bottom plate 411 to provide rigid support for the transported battery accessories and ensure parallel accuracy with the ceiling rail assembly 2 and the ground rail assembly 3.

[0047] Two alternating platform components 42 are installed on the upper surface of the base plate 411. The alternating platform component 42 serves as the core module of the load-bearing platform assembly 4 to realize rapid replacement of multi-layer goods, including an alternating motor 421. The alternating motor 421 adopts a servo motor. A support block is installed under the motor, and the support block is fixed to the base plate 411 by welding. A conveyor belt 422 is installed at the driving end of the alternating motor 421. The alternating motor 421 and the conveyor belt 422 adopt a double-pulley vertical transmission structure, and efficient power transmission is achieved through the pulleys distributed up and down. A flat keyway is processed on the end of the motor drive shaft, and the center hole of the lower pulley is fixed to the alternating motor 421 drive shaft by a flat key. The keyway and the motor shaft slot are precisely matched, and a rotating rod 423 is embedded in the center hole of the upper pulley to form an up and down vertical transmission path.

[0048] The rotating rod 423 serves as the core transmission hub of the alternating platform component 42. One side of the driving end is embedded in the center hole of the pulley above the conveyor belt 422 through an interference fit to transmit torque. The transmission end on the other side of the rotating rod 423 is installed with a track gear set 425, which is embedded in the spline hole of the center gear of the track gear set 425 through an interference fit to transmit rotational power. The middle support section of the rotating rod 423 is installed with a bearing seat 424. The bearing seat 424 adopts a split cast iron structure and is equipped with a new roller bearing. A support is installed under the bearing seat 424 to provide rigid support for the rotating rod 423, the conveyor belt 422, and the track gear set 425. The bearing seat 424 ensures that the rotating rod 423 and the track gear set 425 are installed coaxially, thereby realizing synchronous rotation of the gear set and the rotating rod 423.

[0049] The orbital gear set 425 consists of a central gear and an orbital gear. The central hole of the central gear is spline-connected to the rotating rod 423. Under the drive of the alternating motor 421, the orbital gear rotates on a fixed axis. The tooth surface of the orbital gear meshes with the central gear, and the orbital gear rotates while revolving around the central gear, forming a planetary motion. A connecting rod 426 is embedded in the central hole of the orbital gear of the orbital gear set 425. The connecting rod 426 is designed in a horizontal hanger shape. A single cylindrical protrusion is processed in the middle of the outer driving part, which is embedded in the central hole of the orbital gear. To perform planetary motion, double cylindrical protrusions are machined at both ends of the inner constraint part of the connecting rod 426, and the extended surface of the double cylindrical protrusions is connected to the fork component 43. A cross guide rail 427 is installed on the side of the connecting rod 426 close to the double cylindrical protrusions. The double cylindrical protrusions are embedded in the vertical and horizontal slide grooves of the cross guide rail 427 to limit the movement trajectory of the connecting rod 426. The cross guide rail 427 adopts a cross-shaped slide groove design, and the width of the vertical slide groove and the horizontal slide groove are adapted to the cylindrical end of the connecting rod 426. The cross guide rail 427 is fixed to the upper surface of the support block and is perpendicular to the fork component 43.

[0050] In the alternate motion process, the alternating current motor 421 drives the rotating shaft 423 connected by the key as the power source. The rotating shaft 423 drives the center gear of the orbit gear set 425 to rotate, and the center gear is engaged with the orbit gear to make the orbit gear perform the planetary motion of "revolution around the center gear + self-rotation". The orbit gear converts the planetary motion into the "vertical lifting + horizontal shifting" compound action of the connecting rod 426 along the cross rail 427 through the connecting rod 426. The double-cylinder protrusions of the inner side constraint part of the connecting rod 426 slide in the sliding groove of the cross rail 427, and the trajectory is limited by the guide rail. At the same time, the double-cylinder protrusions of the connecting rod 426 are connected to the fork assembly 43 on both sides, and the connecting rods 426 of the two sides of the alternate platform assembly 42 move synchronously and reversely, pushing the fork assembly 43 to complete the "upper layer extension - lower layer retraction" or "lower layer extension - upper layer retraction" alternate switching. The planetary gear transmission builds the basic power transmission path, and the connecting rod 426 and the cross rail 427 constrain the motion trajectory to realize the upper and lower layer alternate operation of the fork assembly 43.

[0051] The fork assembly 43 is the core execution unit of the carrying platform assembly, including a material conveying platform 431 designed with an aluminum alloy honeycomb composite plate structure. The bottom of the material conveying platform 431 is installed with a fork motor 432 through T-shaped bolts. The fork motor 432 is a direct current servo motor integrated with a brake device. The axis of the fork motor 432 is parallel to the material conveying platform 431, and the both ends are installed with a shaft coupling 433 to realize bidirectional power output. At the same time, the shaft coupling 433 provides overload protection for the fork motor 432 to avoid damage to the components.

[0052] The both sides of the material conveying platform 431 are installed with a connecting rod 434, one end of which is welded and fixed with the material conveying platform 431, and the other end is fully welded with the double-cylinder protrusions of the alternate platform assembly 42. The top of the material conveying platform 431 is installed with a fork frame 435, which is a two-stage nested structure made of aluminum alloy and realizes telescopic guiding through a linear bearing. The middle part of the inside of the fork frame 435 is installed with a rack 436. A pinion is installed between the rack 436 and the shaft coupling 433 below. The rack 436 is a helical gear rack arranged along the telescopic direction of the fork frame 435 and engaged with the pinion driven by the fork motor 432. The both sides of the rack 436 are installed with a roller 437 made of nylon rubber, which is embedded in the U-shaped guide rail of the fork frame 435 to assist the linear motion of the rack 436. The fork frame 435 realizes bidirectional telescopic motion through the forward and reverse rotation of the fork motor 432.

[0053] It should be noted that the two groups of alternating platform components 42 on the base plate 411 are arranged in a spatially staggered manner rather than being symmetrically distributed along the center line of the base plate. The two groups of alternating platform components 42 are located on both sides of the width direction of the material transport platform 431, and the double cylindrical protrusions are rigidly connected to the edges of the two sides of the material transport platform 431 through connecting rods 434, forming a two-way drive structure. In this layout, the rotation center axes of the two groups of alternating platform components 42 are non-coaxially distributed with the center line of the material transport platform 431, and the spacing distance is equal to the width of the material transport platform 431. The track gear sets 425 and connecting rods 426 of the two groups of alternating platform components 42 are arranged in a mirror image. When the alternating motor 421 drives the rotating rod 423 to rotate, the planetary motion of the orbital gears on both sides is converted into a synchronous and reverse compound displacement through the connecting rod 426. When the connecting rod 426 of the platform on one side extends upward along the cross guide rail 427, the connecting rod 426 of the platform on the other side is synchronously retracted downward, forming a two-way push-pull driving force on the fork component 43.

[0054] Working principle: When the battery parts stacking conveyor is working, the column assembly 1 serves as the main support, and the ceiling rail assembly 2 at the top and the ground rail assembly 3 at the bottom form a horizontal guide frame. The lifting motor 15 drives the wire drum 14 to reel in and release the wire rope, and drives the supporting platform assembly 4 to rise and fall vertically along the column 11 through the wire pulley 412 on the bottom plate component 41. The ceiling rail running wheels 23 and the ground rail running wheels 33 roll on the ceiling rail track 21 and the ground rail track 31, and cooperate with the forward motor 34 to realize the horizontal movement of the supporting platform assembly 4; the bottom plate component 41 of the supporting platform assembly 4 is the basic support, and the alternating platform component 42 drives the conveyor belt 422 through the alternating motor 421 to drive the rotating rod 423 to rotate, so that the central gear of the track gear set 425 drives the track orbiting gear to perform planetary motion, and through the connecting rod 426 converts the movement into a compound action of vertical lifting and horizontal lateral movement along the cross guide 427, pushing the fork component 43 to complete the alternating switching between the upper and lower layers. The fork motor 432 drives the rack 436 and the roller 437 through the coupling 433 to realize the two-way extension and retraction of the fork frame 435, thereby completing the picking and placing of the goods; when working, the load-bearing platform first moves horizontally to the target position, and then rises and falls vertically to the corresponding layer. The alternating platform component 42 switches the working position, and the fork frame 435 extends to pick up the goods and then retracts, and then moves to the target layer to unload the goods, and so on. This design breaks through the traditional single-layer handling mode through the collaboration of multiple components, realizes the efficient transfer of multi-layer goods, solves the problem of low efficiency of single-piece transportation in existing technologies, improves the logistics efficiency of automated production lines, and ensures the accuracy and safety of operations.
