Description

Technical Field

[0001] This utility model relates to the field of cargo transportation technology, specifically to an integrated assembly and testing line for multiple models of large liquid-cooled energy storage cabinets. Background Technology

[0002] With the vigorous development of the national new energy industry, electricity storage has become crucial, especially with the emergence of a large number of large-scale energy storage facilities on the power grid. Large-scale liquid-cooled integrated energy storage cabinets are widely used. Due to differences in usage locations, environments, and systems, there are many models and sizes of large-scale liquid-cooled integrated energy storage cabinets, but their production, assembly, and testing processes are basically the same.

[0003] Large energy storage cabinets are generally quite large, and forklifts are often used to transport them to the assembly line. The internal components of these cabinets are also heavy and require forklift handling. However, forklift loading presents several problems: First, the large cabinets can obstruct the forklift driver's view, making it difficult to see objects ahead and increasing the risk of collisions between the forklift and the assembly line. Second, precise control of forklift unloading is difficult, resulting in unloading materials from different work surfaces, which makes subsequent manual operation inconvenient. Utility Model Content

[0004] (I) Technical Solution

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-model large liquid-cooled energy storage cabinet co-line assembly and testing integrated line.

[0006] The specific technical solution is as follows:

[0007] A multi-model large liquid-cooled energy storage cabinet assembly and testing integrated line includes an assembly line, a testing line, a rotary translation vehicle, and a unloading line. The assembly line and the unloading line are located on the same straight line. The rotary translation vehicle is located between the assembly line and the unloading line and can reciprocate between them. The testing line consists of multiple sets and is perpendicular to the straight line containing the assembly line and the unloading line. The assembly line has cabinet loading stations and accessory loading stations. Anti-collision bars are provided on the sides of the cabinet loading stations and accessory loading stations. The cabinet loading stations are also equipped with limiters. The limiters specifically include guide rails, a first servo cylinder, a fixed frame, a movable frame, and guide wheels. The movable frame can slide along the guide rail. The cylinder body and cylinder head of the first servo cylinder are fixed on the fixed frame and the movable frame, respectively. The guide wheels are fixed on the movable frame near the assembly line. The extension and retraction of the first servo cylinder drives the movable frame to extend and retract along the guide rail.

[0008] Furthermore, the accessory loading station is also equipped with an anti-tipping device, which specifically includes a mounting frame, a second servo cylinder, a guide column, a movable plate, a first sensor, a rigid limiter, and a buffer. The second servo cylinder is fixed on the mounting frame, the guide column is located on both sides of the second servo cylinder, the movable plate is installed at the head end of the second servo cylinder and the guide column is fixed on the movable plate, and the first sensor, rigid limiter, and buffer are all fixed on the side of the movable plate near the assembly line.

[0009] Furthermore, the assembly line, testing line, and unloading line are all composed of multiple roller conveyors connected end to end. The conveyor used at the cabinet loading station is a single-row roller conveyor, while the conveyors used in other parts of the assembly line, as well as the conveyors used in the testing line and the unloading line, are double-row roller conveyors. The double-row roller conveyor includes a base plate, side plates, support plates, and rollers. The side plates and support plates are fixed on the base plate, and rollers are provided on both sides of the support plate.

[0010] Furthermore, the cabinet loading station and the parts loading station of the assembly line are equipped with anti-collision platforms on their sides.

[0012] (ii) Beneficial effects

[0013] Compared with the prior art, the technical solution proposed in this utility model has a collision prevention bar at the loading position. On the one hand, it ensures that energy storage cabinets of different sizes can be loaded normally, effectively preventing collisions between forklifts and conveyor lines.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0022] In existing technologies, excessively large cabinets can obstruct the forklift driver's view, making it difficult to see objects in front and increasing the risk of the forklift colliding with the assembly line. On the other hand, forklift unloading cannot be precisely controlled, resulting in unloading materials from different operating surfaces, which makes subsequent manual operation very inconvenient.

[0023] To address the problems existing in the relevant prior art, this utility model proposes a multi-model large liquid-cooled energy storage cabinet co-line assembly and testing integrated line. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1 to 6This utility model proposes a multi-model large liquid-cooled energy storage cabinet co-line assembly and testing integrated line, including assembly line 1, testing line 2, rotary transfer carriage 3, and unloading line 4. Assembly line 1 is a linear conveyor line formed by multiple roller conveyors arranged end to end, and the energy storage cabinets pass through the assembly line. Assembly line 1 and unloading line 4 are located on the same straight line. Rotary transfer carriage 3 is located between assembly line 1 and unloading line 4 and can reciprocate between them. The rotary transfer carriage 3 is a specific existing design and includes a reciprocating carriage 301. The reciprocating carriage 301 has a rotating mechanism on its upper part, and a roller conveyor is located on the upper part of the rotating mechanism. Specifically, the rotating mechanism includes a disc 302 and a drive. The disc-rotating motor 303 and gear mechanism can also be driven by belt drive; this is not a limitation. A position sensor is installed on the reciprocating carriage to control it to stop at a designated position. Test line 2 consists of multiple sets perpendicular to the assembly line and unloading line. The test line is also formed by multiple sets of roller conveyors arranged end-to-end. Assembly line 1 has cabinet loading stations and component loading stations. At the cabinet loading station, a forklift transports the cabinet onto assembly line 1, and then the energy storage cabinet moves along the assembly line. When the energy storage cabinet reaches the component loading station, a forklift transports the component into the cabinet for installation and fixation. The component loading station has at least [number missing]. One anti-collision bar 15 is installed on the side of both the cabinet loading station and the parts loading station. Because the large energy storage cabinet is large, the forklift driver's forward view is obstructed when loading by the forklift. Therefore, the anti-collision bar 15 is installed on the side of the cabinet loading station to prevent the forklift wheels from rolling forward and to avoid the forklift directly hitting the line and causing damage to the line. At the same time, the cabinet loading station is also equipped with a limiter 5. The limiter 5 specifically includes a guide rail 501, a first servo electric cylinder 502, a fixed frame 503, a movable frame 504, and a guide wheel 505. The movable frame 504 can slide along the direction of the guide rail 501. The cylinder body and cylinder head of the first servo electric cylinder 502 are respectively fixed to the fixed frame. On 503 and the movable frame 504, the guide wheel 505 is fixed to the end of the movable frame 504 near the assembly line 1. The first servo electric cylinder 502 extends and retracts, driving the movable frame 504 to extend and retract along the guide rail 501. When the energy storage cabinet is placed on the assembly line 1, the first servo electric cylinder 502 extends, driving the movable frame 504 to extend. The guide wheel 501 contacts the back of the energy storage cabinet, thereby pushing the energy storage cabinet forward. This achieves the purpose of adjusting the front and rear position of the energy storage cabinet on the assembly line 1. This ensures that the energy storage cabinet moves forward to the side of the assembly line where subsequent processing is located, making subsequent processing more convenient without requiring personnel to climb onto the assembly line 1 for secondary position adjustment.

[0025] When a forklift is loading and assembling parts, to prevent the forklift arm from overextending and tipping over the energy storage cabinet, an anti-tipping device 6 is installed at the parts loading station. This device includes a mounting bracket 601, a second servo cylinder 602, guide pillars 603, a movable plate 604, a first sensor 605, a rigid limiter 606, and a buffer 607. The second servo cylinder 602 is fixed to the mounting bracket 601, the guide pillars 603 are located on both sides of the second servo cylinder 602, the movable plate 604 is installed at the head end of the second servo cylinder 602, and the guide pillars 603 are fixed to the movable plate 604. The first sensor... 605, rigid limiter 606, and buffer 607 are all fixed on the side of the movable plate near the assembly line. Specifically, before loading, the second servo cylinder 602 extends and drives the movable plate 604 to move forward, so that the buffer 607 and rigid limiter 606 contact the back of the energy storage cabinet. This can effectively prevent the forklift from pushing the energy storage cabinet over during assembly. The first sensor 605 is used to detect the distance from the movable plate 604 to the back of the energy storage cabinet. When the distance changes, it issues a command to prompt the forklift driver to stop the operation. Specifically, it can be connected to the alarm light to provide a warning through a buzzer or flashing light.

[0026] Assembly line 1, testing line 2, and unloading line 4 are all composed of multiple roller conveyors connected end to end. The roller conveyor used at the cabinet loading station is a single-row roller conveyor, which means that there is only one row of conveying rollers along the material conveying direction. The roller conveyors used in other parts of assembly line 1, as well as the conveyors used in testing line 2 and unloading line 4, are double-row roller conveyors. The double-row roller conveyor includes a base plate 7, side plates 8, support plates 9, and rollers 10. The side plates 8 and support plates 9 are fixed on the base plate 7. Rollers 10 are provided on both sides of the support plate 9. Compared with the single-row roller conveyor, the double-row roller conveyor uses two rows of shorter rollers for support, which can effectively improve the load-bearing capacity of the production line. Large energy storage cabinets typically weigh several tons after assembly. Traditional single-row roller conveyors are prone to deformation due to the long rollers, leading to roller bending and damage to the production line. Double-row roller conveyors effectively avoid this problem. To ensure efficient transport of energy storage cabinets on a double-row roller conveyor, when the length of the double-row rollers is 'a' and the width of the support plate is 'b', the minimum depth of the energy storage cabinet that the double-row roller conveyor can support is 'a+b', and the maximum is '2a+b'. Currently, the depth of energy storage cabinets on the market is mostly 1.2-1.6m. Therefore, a roller length of 0.4m and a support plate width of 0.8m can accommodate the size requirements of most energy storage cabinets on the market.

[0027] Meanwhile, to prevent the forklift arm from pressing on assembly line 1 and causing damage during the loading and unloading process, anti-collision platforms 11 are installed on the sides of the cabinet loading station and the parts loading station of assembly line 1. The height of the anti-collision platform 11 is higher than that of assembly line 1. In this way, during the unloading process, the forklift arm will only contact the top surface of the anti-collision platform 11 and will not hit the assembly line 1, thus effectively preventing collisions. At the same time, a set of columns 12 can be installed on the upper part of the anti-collision platform 11. Springs 13 are fitted on the columns 12. A lifting plate 14 is installed on the upper part of the set of columns 12. At the same time, a second sensor 16 is installed at the lower part of the anti-collision platform 11. When the lifting plate 14 is compressed, the column 12 moves downward. When it is compressed to the limit stroke, that is, when the lifting plate 14 and the anti-collision platform 11 are at the same height, the bottom of the column 12 obstructs the normal signal transmission of the second sensor 16, thereby issuing a command to prompt the forklift driver to stop the operation.

[0028] The specific working principle is as follows: The forklift first loads the energy storage cabinet at the cabinet loading station. The anti-collision plate 11 and anti-collision bar can effectively prevent the forklift arm from colliding with the side and top of the assembly line. After loading is completed, the limiter 5 pushes the energy storage cabinet to one side. Subsequent loading is carried out in the same way. This ensures that the operating surfaces of all energy storage cabinets on assembly line 1 are on the same straight line, which is convenient for subsequent operators. After the cabinet loading is completed, the parts loading station loads the parts. During the process, the anti-tipping device can effectively prevent the forklift from pushing the energy storage cabinet over due to operation errors. After assembly is completed, the energy storage cabinet is transported to the end of the assembly line and stops. Then, the rotating and translating carriage 3 connects to the end of the assembly line, allowing the assembled energy storage cabinet to be transported onto the rotating and translating carriage 3. The rotating and translating carriage 3 aligns with any of the test lines 2 through translation and rotation, and then transports the assembled energy storage cabinet to the test line for testing. After the test is completed, it flows out from the rear end of the test line. When the product on the assembly line is unqualified, the unqualified product is directly transported to the unloading line 4 by the rotating and translating carriage 3 for unloading. During the process, position sensors are installed at the assembly line docking position, the test line alignment position, and the unloading line alignment position to ensure that the rotating and translating carriage 3 docks and transports with the assembly line 1, the test line 2, and the unloading line 4.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
