Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a self-plugging capacity distribution cabinet. Background Technology

[0002] Battery cells need to undergo aging tests before leaving the factory. The steps for aging tests are as follows:

[0003] See Figure 1 The operator manually opens the test clip 101 on the aging board 1, then places the tab on the battery cell 2 into the test clip 101. After releasing the hand, the test clip 101 clamps the tab on the battery cell 2.

[0004] See Figure 2 The transfer trolley 3 is provided with several support components 301 arranged at intervals from top to bottom. There is a placement space between two adjacent support components 301 for horizontally inserting an aging board 1. When the aging board 1 is fully loaded (all test clips 101 are clamped with battery cells 2), the operator inserts the aging board 1 into the placement space of the transfer trolley 3 for temporary storage.

[0005] After the transfer trolley 3 is filled with aging boards 1, the operator moves the transfer trolley 3 to the capacity testing cabinet, puts the aging boards 1 into the capacity testing cabinet, and inserts the power supply plug 102 (a circuit board with several gold fingers) of the aging boards 1 into the power supply slot of the capacity testing cabinet. Then the capacity testing cabinet supplies power to the aging boards 1, and the aging boards 1 execute the corresponding aging test program to realize the aging test of the battery cells 2.

[0006] The problem with the above process is that operators need to manually remove the aging boards one by one from the transfer cart and put them into the capacity cabinet, and also connect the aging boards to the corresponding power supply slots. This results in high labor costs and extremely low work efficiency.

[0007] Therefore, the existing capacity distribution cabinet needs to be improved to solve the problems that it cannot automatically receive the aging boards on the transfer trolley and cannot automatically plug and unplug the aging boards from the power supply slot. Summary of the Invention

[0008] One objective of this invention is to provide a self-pluggable capacity distribution cabinet that can not only mechanically receive aging boards from a transfer trolley, but also mechanically plug and unplug the aging boards from the power supply slots, thus saving manpower and improving work efficiency.

[0009] To achieve the above objectives, the present invention provides a self-pluggable compartment cabinet, comprising:

[0010] The plate fixing mechanism includes a plurality of positioning support plates arranged at intervals from top to bottom, and an insertion space for inserting aging plates is provided between two adjacent positioning support plates.

[0011] A vertical drive mechanism, which is connected to the fixed plate mechanism, is used to drive the fixed plate mechanism to move up and down;

[0012] The insertion and removal mechanism is located on the side of the fixing plate mechanism and includes a plurality of power supply sockets arranged at intervals from top to bottom; the side of the power supply socket near the positioning support plate is provided with a power supply slot for inserting the power supply plate of the aging board; the power supply socket is arranged one-to-one with the positioning support plate and is used to supply power to the inserted aging board.

[0013] A horizontal drive mechanism, connected to the insertion / removal mechanism, is used to drive the insertion / removal mechanism closer to or further away from the fixing mechanism, so that the aging board is inserted into or pulled out of the corresponding power supply slot.

[0014] Preferably, the aging plate is provided with a plurality of vertically penetrating positioning holes, and the upper surface of the positioning support plate is provided with positioning pins corresponding to the positioning holes.

[0015] Preferably, the compartment cabinet is provided with a trolley insertion space for a transfer trolley to be inserted, and the two sides of the trolley insertion space are provided with guide wheels that are rotatably connected to the outer side of the transfer trolley.

[0016] Preferably, the two sides of the insertion space are further provided with lower limiting mechanisms, the lower limiting mechanisms including:

[0017] A lower fixing seat, which is fixed to the side of the insertion space;

[0018] The lower slider is slidably connected to the lower fixed seat;

[0019] A lower limit cylinder, the telescopic end of which is fixedly connected to the lower slider, is used to drive the lower slider to extend into the insertion space.

[0020] Preferably, the lower limit mechanism further includes an inbound photoelectric sensor, which is used to sense the distance between the transfer trolley and the fixed plate mechanism.

[0021] Preferably, the upper and lower parts of the insertion space are provided with several spring pins to buffer the impact on the self-plugging compartment cabinet when the transfer trolley enters the insertion space.

[0022] Preferably, the fixing mechanism further includes an inverted U-shaped frame, and each of the positioning support plates is fixed inside the inverted U-shaped frame;

[0023] The self-pluggable compartment cabinet also includes an inverted U-shaped frame, and the fixing mechanism is located inside the inverted U-shaped frame;

[0024] The vertical drive mechanism is fixed above the outer inverted U-shaped frame, and its drive end passes through the top of the outer inverted U-shaped frame and is fixedly connected to the inner inverted U-shaped frame.

[0025] Preferably, the outer inverted U-shaped frame is provided with an upper limit mechanism, the upper limit mechanism comprising:

[0026] An upper limit plate, which is located above the outer inverted U-shaped frame;

[0027] A vertical guide post, the upper end of which is fixedly connected to the upper limit plate; the middle part passes through the outer inverted U-shaped frame and is slidably connected to the outer inverted U-shaped frame; the lower end is fixedly connected to the top of the inner inverted U-shaped frame.

[0028] An upper fixing seat is fixed to the top of the outer inverted U-shaped frame;

[0029] The upper slider is slidably connected to the upper fixed seat;

[0030] An upper limit cylinder, the telescopic end of which is fixedly connected to the upper slider, is used to drive the upper slider to extend below the upper limit plate.

[0031] The beneficial effects of this invention are as follows: It provides a self-plugging compartment cabinet. Initially, the fixing mechanism is positioned low. The operator pushes a transfer trolley containing aging boards into the self-plugging compartment cabinet, with each aging board inserted precisely into a corresponding insertion space. Then, a vertical drive mechanism raises the fixing mechanism slightly, so that the position of each positioning support plate is higher than the position of the corresponding support component on the transfer trolley. Therefore, each layer of aging boards is lifted and fixed by its corresponding positioning support plate, separating the aging boards from their corresponding support components. The operator can then pull out the transfer trolley, thus achieving mechanized transfer of the aging boards. Next, a horizontal drive mechanism moves the plugging mechanism closer to the fixing mechanism. The power supply slots on each power supply socket connect with the power supply sockets on the corresponding aging boards, thereby supplying power to each aging board so that each aging board can perform the aging test procedure. After the test is completed, the horizontal drive mechanism moves the plugging mechanism away from the fixing mechanism, separating each power supply socket from its corresponding aging board, thus achieving mechanized plugging and unplugging of the power supply slots and aging boards. Therefore, the self-plugging capacity distribution cabinet provided by the present invention can not only mechanically receive aging boards on the transfer trolley, but also realize the mechanical plugging and unplugging of aging boards and power supply slots, which saves manpower and improves work efficiency.

[0057] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0058] In the description of this invention, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present simultaneously. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be an intermediate component present simultaneously.

[0059] Furthermore, terms such as “long,” “short,” “inner,” and “outer” indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the purpose of describing the present invention and are not intended to indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of the present invention.

[0060] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0061] See Figures 3 to 11This embodiment provides a self-plugging compartment cabinet, including a fixed plate mechanism 4, a vertical drive mechanism 5, a plugging mechanism 6, and a horizontal drive mechanism 7.

[0062] See Figure 5 The fixing mechanism 4 includes several positioning support plates 401 arranged at intervals from top to bottom, with an insertion space for inserting aging boards between adjacent positioning support plates 401. The vertical drive mechanism 5 is connected to the fixing mechanism 4 and is used to drive the fixing mechanism 4 to move up and down. The insertion and removal mechanism 6 is located on the side of the fixing mechanism 4 and includes several power supply bases 601 arranged at intervals from top to bottom; the side of the power supply base 601 near the positioning support plate 401 has a power supply slot 6011 for inserting the power supply plate of the aging board; the power supply base 601 and the positioning support plate 401 are arranged one-to-one to supply power to the inserted aging board. The horizontal drive mechanism 7 is connected to the insertion and removal mechanism 6 and is used to drive the insertion and removal mechanism 6 to move closer to or away from the fixing mechanism 4, so that the aging board is inserted into or removed from the corresponding power supply slot 6011.

[0063] See Figures 8-10 This invention provides a self-plugging compartment cabinet. Initially, the fixing mechanism 4 is positioned low, and the operator pushes the transfer trolley 3 containing the aging boards into the self-plugging compartment cabinet, with each aging board inserted into a corresponding insertion space. Then, the vertical drive mechanism 5 drives the fixing mechanism 4 slightly upward, so that the position of each positioning support plate 401 is higher than the position of the corresponding support component on the transfer trolley 3. Therefore, each layer of aging boards is lifted and fixed by the corresponding positioning support plate 401, separating the aging boards from the corresponding support components. The operator can then pull out the transfer trolley 3, thereby achieving mechanized transfer of the aging boards. Next, the horizontal drive mechanism 7 drives the plugging mechanism 6 closer to the fixing mechanism 4, and the power supply slots 6011 on each power supply base 601 are plugged into the power supply sockets on the corresponding aging boards, thereby supplying power to each aging board so that each aging board can perform the aging test procedure. After testing, the horizontal drive mechanism 7 drives the insertion and removal mechanism 6 away from the plate fixing mechanism 4, and each power supply socket 601 separates from the corresponding aging board, thereby realizing the mechanized insertion and removal of the power supply slot 6011 and the aging board. Therefore, the self-inserting capacity distribution cabinet provided by the present invention can not only mechanically receive the aging board on the transfer trolley 3, but also realize the mechanized insertion and removal of the aging board and the power supply slot 6011, which saves manpower and improves work efficiency.

[0064] Optionally, the aging board is provided with several vertically penetrating positioning holes, and the upper surface of the positioning support plate 401 is provided with positioning pins 4011 corresponding to the positioning holes. Specifically, when the transfer trolley 3 sends the aging board into the insertion space, the lower limit mechanism 9 keeps the transfer trolley 3 and the distribution cabinet relatively fixed. At this time, the positioning pins 4011 are located directly below the positioning holes. Therefore, when the positioning support plate 401 rises, the positioning pins 4011 are inserted into the corresponding positioning holes, so that the aging board and the positioning support plate 401 are kept relatively fixed in the horizontal direction, preventing the aging board from moving when the insertion and removal mechanism 6 contacts the aging board.

[0065] In this embodiment, the compartment cabinet is provided with a trolley space for the transfer trolley 3 to be inserted. Guide wheels 8 are provided on both sides of the trolley space and are rotatably connected to the outer sides of the transfer trolley 3. Specifically, the guide wheels 8 are provided to ensure that the transfer trolley 3 enters the trolley space from the opening side along a designated path.

[0066] The insertion space is further provided with lower limiting mechanisms 9 on both sides. Each lower limiting mechanism 9 includes a lower fixed base 901, a lower slider 902, a lower limiting cylinder 903, and an entry photoelectric sensor 904. The lower fixed base 901 is fixed to the side of the insertion space. The lower slider 902 is slidably connected to the lower fixed base 901. The telescopic end of the lower limiting cylinder 903 is fixed to the lower slider 902, used to drive the lower slider 902 into the insertion space. The entry photoelectric sensor 904 is used to sense the distance between the transfer trolley 3 and the fixing mechanism 4.

[0067] See Figure 9 Specifically, the transfer trolley 3 has a lower limit protrusion 302 on its side near the lower slider 902. When the transfer trolley 3 is inserted into the insertion space, the lower limit cylinder 903 drives the lower slider 902 to extend, so that the lower slider 902 is located between the lower limit protrusion 302 and the opening side of the insertion space, blocking the path of the lower limit protrusion 302 out of the insertion space, thus locking the transfer trolley 3 in the insertion space. Alternatively, the transfer trolley 3 has a lower limit groove on its side near the lower slider 902. When the transfer trolley 3 is inserted into the insertion space, the lower limit cylinder 903 drives the lower slider 902 to extend, so that the lower slider 902 is inserted into the lower limit groove, thus locking the transfer trolley 3 in the insertion space. As the operator inserts the transfer trolley 3 into the insertion space, the distance between the transfer trolley 3 and the fixing mechanism 4 decreases. When the transfer trolley 3 reaches the predetermined position (the positioning hole is directly above the positioning pin 4011), the inlet photoelectric sensor 904 senses that the distance between the transfer trolley 3 and the fixing mechanism 4 meets the preset condition. The control system then controls the lower limit cylinder 903 to extend, locking the transfer trolley 3 within the insertion space. Then, the vertical drive mechanism 5 and the horizontal drive mechanism 7 operate sequentially to achieve the aging test.

[0068] Optionally, the upper and lower parts of the insertion space are provided with several spring pins 10 to buffer the impact on the self-plugging compartment cabinet when the transfer trolley 3 enters the insertion space.

[0069] The fixing mechanism 4 further includes an inverted U-shaped frame 402. Each of the positioning support plates 401 is fixed within the inverted U-shaped frame 402. The self-pluggable compartment cabinet also includes an outverted U-shaped frame 11, and the fixing mechanism 4 is located within the outverted U-shaped frame 11. The vertical drive mechanism 5 is fixed above the outverted U-shaped frame 11, and its drive end passes through the outverted U-shaped frame 11 and is fixedly connected to the top of the inverted U-shaped frame 402.

[0070] Preferably, the vertical drive mechanism 5 is a telescopic cylinder, with the cylinder body fixed on the outer inverted U-shaped frame 11, and the telescopic end passing through the outer inverted U-shaped frame 11 and then fixedly connected to the top of the inner inverted U-shaped frame 402.

[0071] The outer inverted U-shaped frame 11 is provided with an upper limit mechanism 12. The upper limit mechanism 12 includes 1201, a vertical guide post 1202, an upper fixed seat 1203, an upper slider 1204, and an upper limit cylinder 1205. 1201 is located above the outer inverted U-shaped frame 11. The upper end of the vertical guide post 1202 is fixedly connected to 1201; the middle part passes through the outer inverted U-shaped frame 11 and is slidably connected to the outer inverted U-shaped frame 11; the lower end is fixedly connected to the top of the inner inverted U-shaped frame 402. The upper fixed seat 1203 is fixedly mounted on the top of the outer inverted U-shaped frame 11. The upper slider 1204 is slidably connected to the upper fixed seat 1203. The telescopic end of the upper limit cylinder 1205 is fixedly connected to the upper slider 1204, and is used to drive the upper slider 1204 to extend below 1201.

[0072] Specifically, when the vertical drive mechanism 5 drives the fixed plate mechanism 4 to rise, the inverted U-shaped frame 402 can make 1201 rise through the guide post. Then, the upper limit cylinder 1205 drives the upper slider 1204 to slide horizontally below 1201, blocking the downward movement path of 1201 and preventing the fixed plate mechanism 4 from suddenly falling due to a malfunction of the vertical drive mechanism 5.

[0073] In this embodiment, see Figure 11The horizontal drive mechanism 7 is a telescopic cylinder. Several (e.g., three) power supply sockets 601 are grouped together. One end of each group of power supply sockets 601 is fixed to a connecting plate 602, and the other end is fixed to another connecting plate 602. Each connecting plate 602 is connected to the telescopic end of a horizontal drive mechanism 7, meaning two horizontal drive mechanisms 7 form a group, driving three power supply sockets 601. The groups of horizontal drive mechanisms 7 are arranged sequentially from top to bottom (the number of horizontal drive mechanisms 7 is 2 / 3 of the number of power supply sockets 601). In some other embodiments, each group of horizontal drive mechanisms 7 may also drive one, two, four, or more power supply sockets 601.

[0074] Optionally, an electrical control box is also fixed to the top of the outward inverted U-shaped frame 11.

[0075] See Figures 8-10 The working process of the self-pluggable compartment cabinet provided in this embodiment is as follows:

[0076] ① The operator inserts the transfer trolley 3, which is filled with aging boards, into the insertion space;

[0077] ② When the vehicle photoelectric sensor 904 senses that the transfer trolley 3 has reached the designated position, the lower limit cylinder 903 drives the lower slider 902 to extend and lock the transfer trolley 3 in the insertion space; at this time, the positioning hole on the aging plate is just above the positioning pin 4011 on the positioning support plate 401.

[0078] ③ The vertical drive mechanism 5 drives the fixed plate mechanism 4 to rise (1201 rises with the fixed plate mechanism 4). The positioning support plate 401 lifts the aging board of the transfer trolley 3, and the positioning pin 4011 is inserted into the positioning hole to achieve the relative position constraint between the aging board and the positioning support plate 401 in the horizontal direction.

[0079] ④ The upper limit cylinder 1205 drives the upper slider 1204 to extend below 1201 to prevent the fixed plate mechanism 4 from suddenly falling.

[0080] ⑤ The lower limit mechanism 9 retracts, and the operator pulls out the transfer trolley 3;

[0081] ⑥ The horizontal drive mechanism 7 extends, and the plug-in mechanism 6 is inserted into the power supply socket of the aging board. After the aging board is powered on, it will undergo an aging test.

[0082] ⑦ After the aging test is completed, the horizontal drive mechanism 7 retracts, the insertion and removal mechanism 6 is pulled out, and the operator inserts the empty transfer trolley 3. The lower limit cylinder 903 extends to lock the transfer trolley 3. The upper limit cylinder 1205 retracts, the vertical drive mechanism 5 lowers the fixing plate mechanism 4, and the aging plate returns to the support assembly of the transfer trolley 3. The lower limit cylinder 903 retracts, and the operator removes the transfer trolley 3, completing the aging test.

[0083] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
