Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet assembly technology, specifically to a turnover device for assembly line assembly of large energy storage cabinets. Background Technology

[0002] The existing large energy storage cabinet frames typically weigh over 1000 kg, sometimes even reaching 1500 kg, with the total weight of the assembled product exceeding 2000 kg, sometimes even reaching 2700 kg. Existing assembly lines lack dedicated transmission or transport devices. Investing in a large-scale assembly line or AGV (Automated Guided Vehicle) system specifically for this product would be prohibitively expensive for small and medium-sized enterprises. Furthermore, such equipment is highly specialized, lacking versatility and having a narrow range of applications. The current assembly process involves placing the frames on the assembly line, with assembly workers moving around to retrieve parts until assembly is complete. Specifically, several (e.g., eight) energy storage cabinet frames are placed on the assembly line using forklifts or cranes, with assembly materials placed on either side of the frames. After all frames are assembled, forklifts or cranes transport the cabinets to the next process, and other cabinet frames are then placed on the assembly line. This assembly method has the following problems: the energy storage cabinet frame cannot be moved, and after multiple frames are arranged, some assembly materials are placed far away. During the assembly process, workers need to walk a long distance to retrieve assembly parts, which reduces assembly efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a turnover device for the assembly of large energy storage cabinets on a production line. The device includes multiple detachable turnover units that engage with the waist-shaped mounting holes on the bottom plate of the energy storage cabinet. Each turnover unit includes omnidirectional rollers, roller bases for mounting the omnidirectional rollers, a rotating spindle that cooperates with the roller bases, and a support body formed around the rotating spindle on the roller bases. The top end of the rotating spindle extends out of the waist-shaped mounting holes and is equipped with a locking block. The locking block can pass through the waist-shaped mounting holes and, under the influence of the rotating spindle rotating at a certain angle, locks the bottom plate of the energy storage cabinet. By incorporating multiple turnover units that mate with the waist-shaped mounting holes on the base plate of the energy storage cabinet, the cabinet can be moved during assembly, allowing the assembly process to resemble an assembly line operation. In this process, assembly materials are arranged in sequence, and assembly can begin when the cabinet is moved to the designated position. The turnover units eliminate the need for long-distance travel to retrieve components, improving assembly efficiency. Furthermore, the turnover units are detachable and can be removed after assembly or before shipment without damaging the cabinet's structure, ensuring the quality of the energy storage cabinet.

[0004] Specifically, the turnover unit is equipped with omnidirectional rollers, roller bases for mounting the omnidirectional rollers, a rotating spindle that cooperates with the roller bases, and a support body formed around the rotating spindle on the roller bases. The support body is used to support the bottom plate of the energy storage cabinet. The omnidirectional rollers are used to move the energy storage cabinet or the energy storage cabinet in assembly. The rotating spindle uses a locking block to lock the bottom plate of the energy storage cabinet or remove the turnover unit from the bottom plate of the energy storage cabinet when it rotates at a certain angle.

[0005] Furthermore, it also includes a support plate disposed between the roller base and the bottom plate of the energy storage cabinet; the support plate is provided with a first through hole, and a limiting bushing plate that cooperates with and limits the side wall of the waist-shaped mounting hole; the limiting bushing plate is provided with a second through hole, and the limiting bushing plate is located inside the waist-shaped mounting hole with its upper and lower ends not exceeding the waist-shaped mounting hole; the rotating spindle passes through the first through hole and the second through hole. By providing the support plate and the limiting bushing plate disposed on the support plate, the support plate supports the bottom plate of the energy storage cabinet, and the limiting bushing plate is located inside the waist-shaped mounting hole to fill the space in the waist-shaped mounting hole excluding the space where the rotating spindle is located, thereby limiting or reducing or avoiding gaps or spaces between the rotating spindle and the waist-shaped mounting hole, thereby reducing mutual impact when the energy storage cabinet moves, and thus avoiding damage between the rotating spindle and the waist-shaped mounting hole.

[0006] Furthermore, the rotating spindle is equipped with a rotating rod that drives the rotating spindle to rotate at a certain angle. The rotating rod facilitates the rotation of the rotating spindle and makes operation convenient.

[0007] Furthermore, the rotation range of the rotating rod is within the notch range of the support body. This design allows the end of the rotating rod to extend beyond the support body, making operation more convenient.

[0008] Furthermore, the roller base is equipped with a limiting structure to restrict the rotation rod. By limiting the rotation rod, the turnover unit is secured in the waist-shaped mounting hole, preventing the rotation rod from driving the main rotating shaft to rotate and causing the turnover unit to fall due to vibration or misoperation. This effectively gives each turnover unit a self-locking function, ensuring safety and reliability.

[0009] Furthermore, the limiting structure is a clamp, and the clamp shaft of the clamp self-locks and limits the rotation of the rotating rod when it is rotated to a certain angle.

[0010] Furthermore, a clamp mounting seat is provided on the roller base, and the clamp is mounted on the clamp mounting seat; a clamp shaft hole is provided on the roller base, and the end of the clamp shaft extends into the clamp shaft hole to self-lock and limit the rotation rod.

[0011] By setting clamps and clamp shaft holes, the clamps and roller base plate can be used to achieve self-locking and limiting fixation of the rotating shaft. The clamp handle is easy to operate and does not require any additional operation. The self-locking and limiting of the rotating shaft can be achieved by operating the clamp handle. The operation is simple, convenient and practical.

[0012] Furthermore, the support body consists of multiple upright plates and two slotted upright plates with the rotating rod slots. The ends of the two slotted upright plates with the rotating rod slots form a notch in the support body. By providing the rotating rod slots, the support body provides a certain degree of support for the rotating rod, reducing the possibility of the rotating rod falling off.

[0013] Furthermore, the outline of the limiting bushing plate is equal to or slightly smaller than the waist-shaped mounting hole. This design allows the limiting bushing plate to limit the waist-shaped mounting hole as much as possible.

[0014] Furthermore, the outer contour of the card block is equal to or slightly smaller than the waist-shaped mounting hole. This design eliminates the need for additional design features, making the card block simple and practical. Attached Figure Description

[0026] Example 1

[0027] like Figure 1-4As shown, this embodiment discloses a turnover device for the assembly line of a large energy storage cabinet. This embodiment utilizes the waist-shaped mounting holes 2 on the base plate 1 of the energy storage cabinet to achieve assembly line turnover. Generally, there are 4, 6, or 8 waist-shaped mounting holes 2 on the base plate 1 of the energy storage cabinet. The turnover device includes multiple turnover units that engage with and are detachable from the waist-shaped mounting holes 2 on the base plate 1 of the energy storage cabinet. Each waist-shaped mounting hole 2 corresponds to one turnover unit. Each turnover unit includes a universal roller 3, a roller base 4 for mounting the universal roller 3, a rotating spindle 5 that cooperates with the roller base 4, and a support body 6 formed around the rotating spindle 5 on the roller base. The top end of the rotating spindle 5 extends out of the waist-shaped mounting hole 2 and is provided with a locking block 7. The locking block 7 can pass through the waist-shaped mounting hole 2 and is locked onto the base plate 1 of the energy storage cabinet under the drive of the rotating spindle 5. Specifically, the structure of the roller base 4 varies; it can be a plate or a frame. In this embodiment, the roller base 4 is a plate, and the universal roller 3 is fixed to the lower surface of the roller base 4. Preferably, the roller base 4 is arranged parallel to the horizontal plane. As for the rotating spindle 5 that cooperates with the roller base 4, it means that a hole or groove is formed on the roller base 4, and one end of the rotating spindle 5 extends into the hole or groove. In this embodiment, a hole is formed on the roller base 4, and a step is formed at one end of the rotating spindle 5, which is inserted into the groove. At the same time, the step rests around the hole. Preferably, the diameter of the hole is equal to or slightly larger than the diameter of the portion of the rotating spindle 5 inserted into the hole. More preferably, the diameter of the hole is slightly larger than the diameter of the portion of the rotating spindle 5 inserted into the hole. This facilitates the insertion of the rotating spindle 5. The rotating spindle 5 is arranged vertically. A support is provided on the roller base 4 around the rotating spindle 5. The support body 6 supports the base plate 1 of the energy storage cabinet. The structure of the support body 6 can be various, such as a combination of plates, columns, or frames. In this embodiment, a combination of plates is preferred. As for how to fix it, there are no specific restrictions, but welding is preferred. When the bottom surface of the base plate 1 of the energy storage cabinet abuts against the top surface of the support body 6, the other end of the rotating spindle 5 extends out of the waist-shaped mounting hole 2. At the same time, a locking block 7 is provided at this end. The locking block 7 can also extend out of the waist-shaped mounting hole 2. The fixing method between the locking block 7 and the rotating spindle 5 can be various, such as integral molding, bolt connection, or welding. In this embodiment, welding is preferred. The locking block 7 locks the base plate 1 of the energy storage cabinet when the rotating spindle 5 rotates at a certain angle. Specifically, in this position, the locking block 7 prevents the rotating spindle 5 from being pulled down from the waist-shaped mounting hole 2.

[0028] Furthermore, it also includes a support plate 8 disposed between the roller base 4 and the energy storage cabinet bottom plate 1. The support plate 8 is fixedly disposed on the support body 6, and its disposal method is varied, including bolt connection and welding, with welding being preferred. In this case, the upper surface of the support plate 8 abuts against the bottom surface of the energy storage cabinet bottom plate 1. The support plate 8 is provided with a first through hole 9, and also with a limiting bushing plate 10 that cooperates with and limits the side wall of the waist-shaped mounting hole 2. The limiting bushing plate 10 is provided with a second through hole 11, and the limiting bushing plate 10 is located within the waist-shaped mounting hole 2 with its upper and lower ends not exceeding the specified limits. The structure of the waist-shaped mounting hole 2 and the limiting bushing plate 10 varies. Preferably, the outline of the limiting bushing plate 10 is equal to or slightly smaller than the waist-shaped mounting hole 2, and more preferably slightly smaller than the waist-shaped mounting hole 2. The limiting bushing plate 10 can also be composed of multiple layers. In this embodiment, it consists of two welded layers. To facilitate welding, multiple recesses are formed on the outer surface of the limiting bushing plate 10 during machining. These recesses can be partially or completely filled during welding. The portion outside the recesses also serves as a limiting element. The connection between the limiting bushing plate 10 and the support plate 8 varies, but welding is preferred. The rotating spindle 5 passes through the first through hole 9 and the second through hole 11. At this time, the lower end face of the locking block 7 just exceeds or slightly exceeds the upper end face of the energy storage cabinet bottom plate 1, and can lock the energy storage cabinet bottom plate 1 when the rotating spindle 5 rotates at a certain angle. The diameters of the first through hole 9 and the second through hole 11 match the positions of the rotating spindle 5 in the first through hole 9 and the second through hole 11, for example, they are equal or slightly larger. The structure of the locking block 7 varies. Preferably, the outer contour of the locking block 7 is equal to or slightly smaller than the waist-shaped mounting hole 2, more preferably slightly smaller. However, it is necessary to ensure that its length dimension can be locked above the waist-shaped mounting hole 2 after rotating at a certain angle.

[0029] Furthermore, the rotating spindle 5 is provided with a rotating rod 12 that drives the rotating spindle 5 to rotate at a certain angle. The structure and position of the rotating rod 12 vary. In this embodiment, it is a columnar structure and is set along the radial direction of the rotating spindle 5. Its position is within the height range of the support body 6, and its rotation range is within the notch range of the support body 6. As for the size of the notch range, it is set according to the optimal position of the locking block 7 locking the waist-shaped mounting hole 2, such as a 90-degree range, that is, after the locking block 7 passes through the second through hole 11 and the waist-shaped mounting hole 2, it rotates 90 degrees. The structure of the notch range depends on the specific structure of the support body 6. In this embodiment, the support body 6 consists of two upright plates 61 and two slotted upright plates 62 with the rotating rod slot 63. The four plates form a near-square or rectangular shape. At a certain corner, the notch range of the support body 6 is formed between the ends of the two slotted upright plates 62 with the rotating rod slot 63. Simultaneously, the rotating slot 63 supports the rotating rod 12 after it has been rotated into position. The connection method between the rotating rod 12 and the rotating spindle 5 can be varied; it can be welded or threaded, with a threaded connection being preferred.

[0030] Furthermore, the roller base 4 is provided with a limiting structure to limit the rotation rod 12. This means that when the rotation rod 12 drives the rotating main shaft 5 to rotate to a certain angle, and the locking block 7 locks the energy storage cabinet bottom plate 1, the limiting mechanism limits and fixes the rotation rod 12 to prevent it from rotating backward and causing the turnover unit to fall off. The limiting structure can take many forms; in this embodiment, the limiting structure is a clamp 13, and the clamp shaft 14 of the clamp 13 self-locks and limits the rotation rod 12 when it has rotated to a certain angle. More specifically, the roller base 4 is provided with a clamp mounting seat 15. As for the mounting method, there are various methods, such as bolt fixing or welding, welding is preferred. As for the structure of the clamp mounting seat 15, there are various methods. In this embodiment, the clamp mounting seat 15 includes a vertical plate and a stiffening plate. The clamp 13 is mounted on the vertical plate. The roller base is provided with a clamp shaft hole 16. The end of the clamp shaft 14 extends into the clamp shaft hole 16 to self-lock and limit the rotation rod 12.

[0031] The usage process of this utility model is as follows:

[0032] When assembling energy storage cabinet frames, the materials to be assembled are arranged in groups of several energy storage cabinets (e.g., 8) according to an assembly line operation method. Each energy storage cabinet frame is equipped with multiple turnover units, typically 4, such as... Figure 5As shown, during installation, the energy storage cabinet frame is hoisted or lifted, and the locking block 7 of the turnover unit is passed through the waist-shaped mounting hole 2. Then, the rotating rod 12 is rotated until the locking block 7 is locked and rotated to the limit. At this time, the handle of the clamp 13 is operated so that the clamp shaft 14 extends into the clamp shaft hole 16, thereby self-locking the rotating rod 12. At this time, the turnover unit is installed. The energy storage cabinet frame can then be pushed or pulled along the set route. When it reaches a certain set position, the corresponding assembly is performed. After completion, the assembly is performed at the next set position until completion. When it is necessary to disassemble the turnover unit, the energy storage cabinet is hoisted or lifted, the handle of the clamp 13 is operated so that the clamp shaft 14 leaves the clamp shaft hole 16 and is lifted to unlock. The rotating rod 12 is then rotated so that the locking block 7 can be removed from the waist-shaped mounting hole 2 to remove the turnover unit.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
