Description

Technical Field

[0001] The present invention belongs to the technical field of electric power facility production, and in particular relates to an automatic assembly device for processing a power distribution cabinet and a use method thereof. Background Art

[0002] Existing power distribution cabinets usually adopt a tall and narrow design. This design is not only conducive to enhancing heat dissipation through natural convection and maintaining a safe level of internal temperature, but also maximizes the use of vertical space in space-constrained environments (such as residential corridors, offices or industrial plants), thereby saving valuable floor space. In addition, such a design also helps to simplify the installation and maintenance process of electrical equipment, and the small base reduces the pressure on the ground, making it easier to fix and install. However, this tall and narrow design leads to the following problems in the assembly and production process of the power distribution cabinet:

[0003] The existing distribution cabinet is mainly composed of two parts: the frame and the shell. The role of the frame is to ensure the overall structural stability and firmness of the distribution cabinet. However, some distribution cabinet assembly equipment on the market, such as the equipment with the patent name "A high-voltage distribution cabinet automatic assembly device" and application number 202410869725.8, can only assemble and produce distribution cabinets with shells but lacking internal frames. The distribution cabinets produced in this way have relatively poor structural stability and firmness and cannot meet high-standard application requirements.

[0004] In addition, considering that the distribution cabinet is usually designed to be tall and narrow, although this design helps to save space and enhance heat dissipation, it also brings about the problem of a large spacing between the bottom frame and the top frame. During the assembly and production process of the frame, if a single station is used for material supply, whether it is mechanical loading or manual loading, there will be a series of challenges. For mechanical loading, long-stroke loading equipment is required, which not only increases the purchase cost of the equipment, but also may increase the complexity and maintenance difficulty of the system. For manual loading, it means that workers need to move frequently between different heights, which not only increases the physical burden of workers, but may also lead to reduced efficiency, thereby affecting production progress.

[0005] Although the dual-station loading method can alleviate the above problems to a certain extent, because it allows material processing at two different locations at the same time, reducing the material handling distance and time, thereby improving work efficiency. However, the dual-station solution is also accompanied by a higher initial investment cost.

[0006] In summary, the current distribution cabinet assembly equipment can only produce distribution cabinets with only an outer shell but no internal frame, resulting in low structural stability and firmness of the finished product, which cannot meet high standards. The assembly of the frame is affected by the tall and narrow design, resulting in inconvenience in single-station loading and increased costs for double-station loading. Summary of the invention

The position and action of the clamp 1 in each state are pre-set, ensuring that the required operations can be accurately performed at each stage; at the same time, by reasonably designing the state transition of the clamp 1, unnecessary operation steps are reduced, and the efficiency and automation of the assembly process are improved.

[0048] Embodiment 2

[0049] This embodiment is mainly to further optimize the first chute 15 in the first embodiment, specifically as follows:

[0050] The upper part of the first slide groove 15 is tilted outward, and the lower part is vertically arranged. The second slide groove 16 is tilted outward. When the frame is erected, the control rod 14 acts on the top of the first slide groove 15 and the second slide groove 16, and the mounting plate 11 and the control block 12 are closest. The control block 12 is moved away from the mounting plate 11, so that the inner clamping plate 131 remains stationary and the outer clamping plate 132 moves toward the outside of the frame, so as to carry out the frame and Place the outer shell between the outer clamping plate 132; after completing the placement of the outer shell between the frame and the outer clamping plate 132, move the control block 12 away from the mounting plate 11 again, so that the inner clamping plate 131 moves toward the inner side of the frame and the outer clamping plate 132 moves toward the outer side of the frame, and then return to the back of the mounting plate 11; then control the distance between the clamp 1 and the bracket 2 to place the outer shell between the frame and the mounting plate 11, and then complete the assembly of the outer shell. Specifically, the design of the inner clamping plate 131 moving inwards and then descending can avoid the collision of the clamping plate 13 with the already placed outer shell or other components when it descends directly, reducing the risk of damage. By moving inwards first and then descending, the misalignment or damage between the outer shell and the frame caused by misoperation can be reduced.

5. A method for using an automatic assembly device for processing a power distribution cabinet, using the automatic assembly device for processing a power distribution cabinet according to claim 4, characterized in that: The method of use comprises assembling the frame, Assembling the frame comprises the following steps: S1. Adjust all the fixtures on the bracket to the retracted state; S2, bringing the fixed frame and the movable frame closer together by using the linear moving component, and then adjusting the clamp on the frame to a clamping state to place the first bracket and the second bracket; S3. Move the fixed frame and the movable frame away from each other by using the linear moving component, and then adjust the clamp on the side beam to a clamping state to place the third bracket.

6. The method of use according to claim 5, characterized in that: The method of use also includes assembling the housing, After the frame is assembled, the shell is assembled, including the following steps: S4, adjusting the first clamp to a loading state and the second clamp to a feeding state, placing the shell between the frame and the outer clamp, and then adjusting the first clamp and the second clamp to a clamping state to connect and fix the shell and the frame; S5. Adjust the first clamp to the loading state and the second clamp to the retracting state to place the shell between the frame and the mounting plate, then adjust the first clamp to the clamping state and the second clamp to the feeding state to connect and fix the shell and the frame; complete the assembly of the power distribution cabinet.

7. The method of use according to claim 6, characterized in that: The method of use also includes returning the material, The return process includes the following steps: S6, the first clamp on the frame is adjusted to a feeding state, and the other clamps are adjusted to a retreat state; S7, bringing the fixed frame and the movable frame closer together through the linear moving component, allowing the movable frame to push the assembled distribution cabinet to complete the material return; at the same time, bringing the fixed frame and the movable frame closer together to prepare for the next assembly.
