Description

Technical Field

[0001] This application relates to the field of battery recycling technology, and in particular to a battery module recycling test fixture. Background Technology

[0002] Lithium-ion batteries are widely used in various fields such as medical care, communications, and transportation due to their large capacity and environmental friendliness. In particular, with the strong promotion of environmentally friendly transportation, the development of electric vehicles is accelerating. As a result, the number of retired battery packs in electric vehicles is also increasing. The capacity of these battery packs varies, and they need to be tested and sorted before they can be reused.

[0003] Currently, the battery recycling testing process involves using clamps to hold the two electrode posts of the battery cell, and bolts are generally used to tighten and fix the battery cell. However, this method can only test a single battery, which is inefficient. Utility Model Content

[0004] The purpose of this application is to provide a battery module recycling test fixture to solve at least one of the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this application provides a battery module recycling test device, including a base, a detection component and a fixing component disposed on the base;

[0006] The fixing component includes a linkage module and several clamping modules. Each clamping module is used to clamp and fix a battery. The linkage module is connected to several clamping modules and is adapted to drive multiple clamping modules to clamp synchronously.

[0007] The detection assembly includes a first fixed plate, a detection unit, and a first driving member. The first driving member is connected to the first fixed plate and is adapted to drive the first fixed plate to move along a first direction. A plurality of first through slots are provided on the first fixed plate along its length direction. The number of first through slots corresponds to the number of clamping modules. Two detection units are detachably provided on each first through slot. The detection units are adapted to be connected to the terminals of the battery.

[0008] In the above process, the operator places the battery to be tested on the base, specifically on the clamping station of a clamping module. Taking a base with two clamping modules as an example, the operator can place two batteries to be tested at a time on the clamping stations of the two clamping modules respectively. Then, the linkage module drives the two clamping modules to clamp the batteries synchronously, thus fixing the batteries. The detection module can be understood as having a corresponding number of detection stations. Each detection station has two detection units. The position of the detection units can be adjusted along the direction of the through slot to adapt to the position of the battery terminals. After the initial adjustment, the position of the detection units does not need to be adjusted again for subsequent detection of the same type of battery. After the battery position is fixed, the first driving component can drive the first fixing plate to move along the first direction, allowing the detection module to contact the battery terminals to detect the battery and ultimately achieve the gradient recycling of the battery. This solution can achieve rapid clamping and fixing of batteries, and can fix multiple batteries at a time to achieve synchronous detection of multiple batteries. The structure is simple and effectively improves the detection efficiency of gradient recycling of batteries.

[0009] Preferably, the clamping module includes a positioning plate and a clamping plate;

[0010] The clamping plate is provided with two clamps and is adapted to clamp the two sides of the battery in the second direction, and the positioning plate is adapted to abut against the bottom surface of the battery;

[0011] The first direction is perpendicular to the second direction;

[0012] In the above process, one side of the battery abuts against the base, while the two sides contact the clamping plates, which clamp the battery. The bottom surface abuts against the positioning plate, thereby achieving multiple positional fixation. Multiple positioning makes the battery position more accurate, which facilitates precise docking of the subsequent testing module.

[0013] Preferably, the linkage module includes a sliding plate, a main board, a connecting rod, and a second driving component;

[0014] The motherboard includes a plurality of first board sections and a connecting section connecting the plurality of first board sections;

[0015] Each of the first plate body portions is rotatably provided with two connecting rods, the two connecting rods are respectively connected to the two sliding plates, a second through groove is formed on the positioning plate along the second direction, and an extension block is formed at one end and passes through the second through groove to connect with the clamping plate;

[0016] The driving end of the second driving element is connected to the motherboard and is adapted to drive the motherboard to move along the first direction;

[0017] In the above implementation process, the second driving component can drive the motherboard to move. When the motherboard approaches the battery in the first direction, it can drive the sliding plates to move away from each other in the second direction under the action of the connecting rod. The movement of the sliding plates also drives the movement of the clamping plates, which frees up space for the battery to be placed. When the cylinder moves in the opposite direction, it will drive the two sliding plates to move closer together, thereby driving the clamping plates to move closer together to achieve centering and clamping of the battery. In this solution, not only is the clamping and fixing of the battery achieved, but the battery is also automatically centered first, which can make the battery position consistent and facilitate subsequent rapid testing.

[0018] Preferably, a first slide rail is provided on the base along a first direction, and the main board is slidably disposed on the first slide rail.

[0019] Preferably, a second slide rail is provided on the base along the second direction, and the sliding plate is slidably disposed on the second slide rail.

[0020] In the above implementation process, the first slide rail can limit the motherboard, thereby allowing the motherboard to move stably along the first direction; similarly, the second slide rail can limit the sliding plate, thereby causing the sliding plate to move stably along the second direction, while ensuring the stability of the clamping plate movement.

[0021] Preferably, the detection unit includes a locking post, an electrical terminal, and a locking bolt;

[0022] The locking bolt is adapted to abut against the first fixing plate and lock the locking post on the first fixing plate. The electrical terminal is provided at one end of the locking post. The locking post has a receiving groove adapted to accommodate the battery terminal. An electrical contact piece is provided in the receiving groove.

[0023] In the above process, the electrode terminals on the battery can be inserted into the receiving slot, and the electrical contacts in the receiving slot can contact the electrode terminals on the battery. Then, the battery can be detected by connecting wires through the electrical terminals located on the locking post. The locking bolt can be used with the first fixing plate to fix it. When it is necessary to adjust the position of the locking post, the locking bolt is loosened, adjusted to the appropriate position, and then tightened.

[0024] Compared with the prior art, the beneficial effects of this application are as follows: This solution can realize the rapid clamping and fixing of batteries, and can fix multiple batteries at one time to realize the synchronous detection of multiple batteries. The structure is simple and effectively improves the detection efficiency of battery gradient recycling. Attached Figure Description

[0034] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0035] Example

[0036] Currently, the battery recycling testing process involves using clamps to hold the two electrode posts of the battery cell, typically secured with bolts. However, this method generally only allows testing of a single battery, resulting in low efficiency. To address these technical problems, this embodiment provides the following technical solution:

[0037] For details, please see Figure 1-3 This embodiment provides a battery module recycling test device, including a base 10, a detection component and a fixing component disposed on the base 10;

[0038] Specifically, the fixing component includes a linkage module and several clamping modules. Each clamping module is used to clamp and fix a battery. The linkage module connects to several clamping modules and is suitable for driving multiple clamping modules to clamp synchronously.

[0039] Specifically, the detection assembly includes a first fixed plate 31, a detection unit 32, and a first driving member 33. The first driving member 33 is connected to the first fixed plate 31 and is adapted to drive the first fixed plate 31 to move along a first direction. A plurality of first through slots 311 are provided on the first fixed plate 31 along its length direction. The number of first through slots 311 corresponds to the number of clamping modules. Two detection units 32 are detachably provided on each first through slot 311. The detection units 32 are adapted to be connected to the battery terminals.

[0040] In the above scheme, the operator places the battery to be tested on the base 10, specifically on a clamping station of a clamping module. Taking a base 10 with two clamping modules as an example, the operator can place two batteries to be tested at a time on the clamping stations of the two clamping modules respectively. Then, the linkage module drives the two clamping modules to clamp the batteries synchronously, thus testing the battery's fixation. The testing module can also be understood as having a corresponding number of testing stations. Each testing station is equipped with two testing units 32. The positions of the testing units 32 can be arranged along the passage. The direction of the slot is adjusted to match the position of the battery terminals, and the position of the detection unit 32 does not need to be adjusted again after the initial adjustment for subsequent detection of the same type of battery; after the battery position is fixed, the first driving component 33 can drive the first fixing plate 31 to move along the first direction, so that the detection module can contact the battery terminals to realize the detection of the battery, and finally realize the gradient recycling of the battery; this solution can realize the rapid clamping and fixing of the battery, and can fix multiple batteries at one time to realize the synchronous detection of multiple batteries. The structure is simple and effectively improves the detection efficiency of the gradient recycling of batteries.

[0041] Specifically, the clamping module includes a positioning plate 22 and a clamping plate 21;

[0042] Furthermore, the clamping plate 21 is provided with two clamping plates adapted to clamp the two sides of the battery in the second direction, and the positioning plate 22 is adapted to abut against the bottom surface of the battery.

[0043] In one embodiment, the first direction and the second direction are perpendicular to each other;

[0044] In the above scheme, one side of the battery abuts against the base 10, while the two sides contact the clamping plates 21, which clamp the battery. The bottom surface abuts against the positioning plate 22, thereby achieving multiple positional fixation. The multiple positioning makes the battery position more accurate, which facilitates the precise docking of the subsequent testing module.

[0045] Specifically, the linkage module includes a sliding plate 41, a main board 43, a connecting rod 42, and a second drive component 44;

[0046] Furthermore, the motherboard 43 includes a plurality of first board sections 431 and a connecting section 432 connecting the plurality of first board sections 431;

[0047] Specifically, each first plate body 431 is rotatably provided with two connecting rods 42, and the two connecting rods 42 are respectively connected to two sliding plates 41; the two connecting rods 42 can be understood as being distributed in a figure-eight shape;

[0048] A second through groove 221 is formed on the positioning plate 22 along the second direction, and an extension block is formed at one end and passes through the second through groove 221 to connect with the clamping plate 21.

[0049] Specifically, the driving end of the second driving component 44 is connected to the motherboard 43 and is adapted to drive the motherboard 43 to move along the first direction;

[0050] In the above scheme, the second driving component 44 can drive the main board 43 to move. When the main board 43 approaches the battery in the first direction, it can drive the sliding plate 41 to move away from each other in the second direction under the action of the connecting rod 42. The movement of the sliding plate 41 also drives the movement of the clamping plate 21, which frees up space for the battery to be placed. When the cylinder moves in the opposite direction, it will drive the two sliding plates 41 to move closer together, thereby driving the clamping plate 21 to move closer together to achieve the centering and clamping of the battery. In this scheme, not only is the clamping and fixing of the battery achieved, but the battery is also automatically centered first, which can make the battery position consistent and facilitate subsequent rapid testing.

[0051] Specifically, a first slide rail 45 is provided on the base 10 along the first direction, and the main board 43 is slidably disposed on the first slide rail 45.

[0052] Furthermore, a second slide rail 23 is provided on the base 10 along the second direction, and the sliding plate 41 is slidably disposed on the second slide rail 23.

[0053] In the above scheme, the first slide rail 45 can limit the main board 43, thereby allowing the main board 43 to move stably along the first direction; similarly, the second slide rail 23 can limit the sliding plate 41, thereby causing the sliding plate 41 to move stably along the second direction, while ensuring the stability of the movement of the clamping plate 21.

[0054] Specifically, the detection unit 32 includes a locking post 321, an electrical terminal 322, and a locking bolt 323;

[0055] It should be noted that the locking bolt 323 is a relatively mature technology in the prior art, so this application will not elaborate on it further.

[0056] Furthermore, the locking bolt 323 is adapted to abut against the first fixing plate 31 and lock the locking post 321 onto the first fixing plate 31. The electrical terminal 322 is provided at one end of the locking post 321. The locking post 321 has a receiving groove adapted to accommodate the battery terminal. An electrical contact piece (not shown in the figure) is provided in the receiving groove.

[0057] In the above scheme, the electrode terminals on the battery can be inserted into the receiving groove, and the electrical contacts in the receiving groove can contact the electrode terminals on the battery. Then, the battery can be detected by connecting wires through the electrical terminals 322 located on the locking post 321. The locking bolt 323 can be used with the first fixing plate 31 to fix it. When it is necessary to adjust the position of the locking post 321, the locking bolt 323 is loosened, adjusted to the appropriate position, and then tightened.

[0058] It should be noted that the electrical terminal 322 is used for connecting external wires, which can be further understood as connecting an external detection device; while the electrical contact piece can be understood as being electrically connected to the electrical terminal 322; the specific structure related to the detection is a relatively mature technology in the prior art, so this application will not elaborate on its specific detection principle; however, it is understood that it does not affect the overall understanding of the solution by those skilled in the art.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application shall fall within the scope of the technical solution of this application.
