Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, and in particular to an automatic cooling line for current transformers. Background Technology

[0002] After dispensing adhesive, the instrument transformers need to be dried in a drying oven. The temperature of the dried instrument transformers exceeds 100°C, so they need to be cooled before subsequent processing. The existing cooling method usually involves placing the drying room on a cooling rack for cooling, but this cooling method has poor cooling efficiency and is not convenient for retrieving the carrier trays that hold the instrument transformers. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an automatic cooling line for current transformers, which can be used for the synchronous cooling of multiple current transformers, with high cooling efficiency and convenient loading and unloading of carriers.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic cooling line for a current transformer, wherein the current transformer is placed on a carrier, and the automatic cooling line comprises:

[0005] A first conveyor line, wherein the first conveyor line conveys the carrier along a first direction;

[0006] A cooling rack is located at the front end of the first conveyor line in the conveying direction. The cooling rack includes placement conveyor lines distributed along a second direction. The placement conveyor lines can convey the carrier along a third direction. A fan is provided at the front end of each placement conveyor line in the conveying direction. The air outlet of the fan faces the corresponding placement conveyor line.

[0007] A transport mechanism is located between the first conveyor line and the cooling rack, and is used to transport the carrier between the first conveyor line and the placement conveyor line.

[0008] The beneficial effects of this utility model are as follows: the first conveyor line transports the carriers, and the handling mechanism is used to move the carriers between the multi-layered cooling racks and the first conveyor line, realizing rapid loading and unloading of the carriers. At the same time, the vertical arrangement of the first conveyor line and the cooling racks saves space. The multi-layered structure of the cooling racks and the cooperation of the placement of the conveyor lines allow multiple carriers to be cooled synchronously on the cooling racks simultaneously.

[0009] Furthermore, the conveying mechanism includes a frame with a first lifting plate that can reciprocate along a second direction. A conveying line is mounted on the first lifting plate, and the conveying line always conveys the carrier along a first direction. The conveying line only needs to be raised and lowered to different heights to connect with the first conveyor line and the placement conveyor line, and then the carrier is moved between the first conveyor line and the placement conveyor lines at different heights via the transmission of the conveying line.

[0010] Furthermore, the stand is located on one side of the end of the placement transmission line, so that the carrier can be evenly distributed on the placement transmission line by moving the placement transmission line in one direction.

[0011] Furthermore, each of the first conveyor line, each of the placement conveyor lines, and the corresponding end of the handling mechanism is equipped with a lifting conveyor assembly. The lifting conveyor assembly includes a second lifting plate that can move up and down. Each of the two second lifting plates is equipped with a transfer conveyor line perpendicular to the horizontal conveying direction of the corresponding first conveyor line and the corresponding conveyor line. By setting up the lifting conveyor assembly, the conveying direction of the vehicle can be changed.

[0012] Furthermore, both the first conveyor line and the placement conveyor line are belt conveyors, each comprising two synchronously moving conveyor belts, with the lifting conveyor assembly located between the two conveyor belts. The transfer conveyor line of the lifting conveyor assembly can move up and down between the two conveyor belts.

[0013] Furthermore, the automatic cooling line also includes a second conveyor line, which is located on the same side of the cooling rack as the first conveyor line. One end of the second conveyor line is connected to a transfer conveyor line on the first conveyor line. The cooled vehicle is transported via the second conveyor line.

[0014] Furthermore, the second conveyor line includes a first section, a second section, and a transition section connecting the two. The first section conveys the carrier along a second direction, and the second section conveys the carrier along a first direction. The second conveyor line is L-shaped and is spliced ​​with the first conveyor line and the cooling rack to form an L-shape, creating a portal structure that saves space.

[0015] Furthermore, the automatic cooling line also includes a return conveyor line located below the second conveyor line and the first conveyor line. The return conveyor line is used to transport the carrier on the return conveyor line to the location of the first conveyor line. Attached Figure Description

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] In the composite diagram below, the first direction is the X-axis, the second direction is the Z-axis, and the third direction is the Y-axis. It is understood that, in order to unify the reference datum and ensure that the descriptions of all structures and components are based on the same coordinate system, this application aims to improve the accuracy and consistency of the descriptions.

[0029] This invention relates to an automatic cooling line for instrument transformers, used to cool instrument transformers at high temperatures and transport and dry them, wherein the instrument transformers are placed on a carrier, and the carrier is transported and cooled on the automatic cooling line.

[0030] See appendix Figure 1 and attached Figure 2 As shown, the automatic cooling line includes a first conveyor line 1, a cooling rack 2, and a handling mechanism 3.

[0031] The first conveyor line 1 conveys the carrier along a first direction, and the cooling rack 2 is located at the front end of the first conveyor line 1 in the conveying direction. The cooling rack 2 is perpendicular to the first conveyor line 1, and the two form an L-shaped structure. See appendix. Figure 3 As shown, the cooling rack 2 includes a frame 21 with multiple placement conveyor lines 22 distributed along a second direction, making full use of the height space to allow multiple rows of vehicles to be placed on the cooling rack 2. Each placement conveyor line 22 can transport the vehicles along a third direction. A fan 23 is provided at the front end of each placement conveyor line 22 in the transport direction, with the fan 23's outlet facing the corresponding placement conveyor line 22. The placement conveyor lines are relatively long, allowing multiple vehicles to be placed simultaneously for cooling. The placement conveyor lines can both store and sequentially transport vehicles, ensuring a uniform distribution of vehicles along the third direction.

[0032] The transport mechanism 3 is located between the first conveyor line 1 and the cooling rack 2. The transport mechanism 3 is used to transport the carrier between the first conveyor line 1 and the placement conveyor line 22. The transport mechanism 3 transports the carriers on the first conveyor line 1 one by one to the placement conveyor line 22.

[0033] In this embodiment, the first conveyor line 1 transports the carriers, and the handling mechanism 3 is used to move the carriers between the multi-layered cooling rack 2 and the first conveyor line 1, enabling rapid loading and unloading of the carriers. Simultaneously, the vertical arrangement of the first conveyor line 1 and the cooling rack 2 saves space. The multi-layered structure of the cooling rack 2, combined with the placement of the conveyor lines, allows for the simultaneous cooling of multiple carriers on the cooling rack 2.

[0034] See appendix Figure 5 As shown, the conveying mechanism 3 includes a frame 31, which is equipped with a first lifting plate 32 that can reciprocate along a second direction. A linear module for driving the first lifting plate 32 to rise and fall is fixed on the frame 31. A conveying line 33 is provided on the first lifting plate 32, which always conveys the carrier along the first direction. The conveying line 33 is first aligned with the first conveyor line 1, and the carrier on the first conveyor line 1 moves onto the conveying line 33. Then, driven by the first lifting plate 32, the conveying line 33 is aligned with a placement conveyor line at a height position, at which point the carrier on the conveying line 33 can move onto the placement conveyor line.

[0035] Because the conveying directions of the transport conveyor line 33 and the placement conveyor line are perpendicular, in order to achieve docking of the carrier between the two, a first lifting and conveying component 24 is provided at the end of the placement conveyor line corresponding to the transport mechanism 3. The first lifting and conveying component 24 is used to transfer the carrier on the transport conveyor line 33 to the placement conveyor line.

[0036] See appendix Figure 4As shown, the first lifting and conveying assembly 24 includes a second lifting plate A242, on which a transfer conveyor line A243 is mounted and moves synchronously. The transfer conveyor line A243 carries a carrier in a first direction. The handling conveyor line 33 is initially aligned with the transfer conveyor line A243, at which point the transfer conveyor line A243 is higher than the placement conveyor line. When the carrier on the handling conveyor line 33 moves to the transfer conveyor line A243, the transfer conveyor line A243 descends, and the carrier on the transfer conveyor line A243 falls onto the placement conveyor line for transport. The first lifting and conveying assembly 24 also includes a drive motor A241 that drives the second lifting plate A242 to move up and down.

[0037] In one embodiment, the stand 31 is located on one side of the end of the placement transmission line 22. In this case, moving the placement transmission line in one direction can evenly distribute the carriers on the placement transmission line.

[0038] The automatic cooling line also includes a second conveyor line 4, which is used to transport the cooled carriers and current transformers from the cooling rack 2. The handling mechanism 3 places the cooled carriers onto the first conveyor line 1. To enable the docking of the first conveyor line 1 and the second conveyor line 4, a second lifting and conveying assembly 11 is provided at the end of the first conveyor line 1 that docks with the handling mechanism 3.

[0039] The second lifting and conveying assembly 11 has the same structure as the first lifting and conveying assembly 24, including a drive motor B, a second lifting plate B, and a transfer conveyor line B. The transfer conveyor line B transports the carrier in a third direction. When the carrier on the cooling platform needs to be transferred to the second conveyor line 4, the handling conveyor line 33 first aligns with the transfer conveyor line B. At this time, the transfer conveyor line B is higher than the first conveyor line 1. After the carrier on the handling conveyor line 33 moves to the transfer conveyor line B, the carrier on the transfer conveyor line B moves in a third direction to the second conveyor line 4 for transfer. At this time, the second conveyor line 4 and the transfer conveyor line B are at the same height.

[0040] Both the first conveyor line 1 and the placement conveyor line are belt conveyors. The belt conveyor line includes two synchronously moving conveyor belts. The lifting conveyor assembly is located between the two conveyor belts, meaning that the transfer conveyor line can move up and down between the two conveyor belts.

[0041] The second conveyor line 4 and the first conveyor line 1 are located on the same side of the cooling rack 2, with one end of the second conveyor line 4 connecting to a transfer conveyor line on the first conveyor line 1. The second conveyor line 4 includes a first section 41, a second section 42, and a transition section 43 connecting the two. The first section 41 conveys the carrier along a second direction, and the second section 42 conveys the carrier along a first direction. At this point, the second conveyor line 4 and the first conveyor line 1 form a U-shaped structure, making full use of space without occupying excessive space in the first and third directions.

[0042] In one embodiment, the second segment 42 is provided with multiple processing stations, and the processing stations can be equipped with processing devices, such as visual inspection and screw tightening devices, to process the cooled current transformer.

[0043] In one embodiment, the current transformer is placed on a carrier, which needs to be recycled after cooling and processing. Therefore, the automatic cooling line also includes a return conveyor line 5 located below the second conveyor line 4 and the first conveyor line 1, which is used to transport the carrier on the return conveyor line 5 to the location of the first conveyor line 1.

[0044] During the automatic cooling line, the current transformers exiting the drying oven are first placed onto carriers. These carriers, containing the current transformers, are then transported via the first conveyor line 1 to the working area of ​​the handling mechanism 3. The handling mechanism 3 then moves the carriers to the placement conveyor line 22 of the cooling rack 2. Once the carriers are evenly distributed on the placement conveyor line 22, the corresponding fans 23 begin blowing air for cooling. After all carriers are placed on each placement conveyor line 22 and left to stand for a specified time, the handling device moves the carriers that entered the cooling rack 2 to the transfer conveyor line B. The cooled carriers are then transported via the transfer conveyor line B to the second conveyor line 4 for further processing of the current transformers. After processing, the dried current transformers are manually removed from the carriers, which are then transported back to the location of the first conveyor line 1 along the return conveyor line 5.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
