Description

Technical Field

[0001] This utility model relates to the field of battery cell testing, specifically a multi-cell synchronous testing adapter. Background Technology

[0002] Electrical performance testing is a necessary step before battery cells leave the factory. This testing verifies the cell's charge / discharge performance, capacity, and internal resistance. During testing, the cell needs to be clamped and positioned to ensure proper contact between the testing equipment's connector and the cell's tabs. Existing telecommunications testing fixtures, as described in publication number "CN113484775A," include a main fixture body and upper and lower clamping bodies mounted on it. These clamping bodies can be brought close together to clamp the connecting pieces (i.e., the cell's tabs) during testing. This type of fixture requires manual alignment of the fixture and cell tabs before bolts are tightened to secure the connection. Each testing cycle can only test one set of cells, and the process involves manual adjustment of the clamping bodies, independent assembly and disassembly of the cells, and manual positioning of the cell's installation position, resulting in low testing efficiency. Therefore, a solution is urgently needed. Utility Model Content

[0003] To avoid and overcome the technical problems existing in the prior art, this utility model provides a multi-cell synchronous detection adapter. This utility model can realize synchronous automatic clamping, positioning and detection of multiple sets of cells, with high detection efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A multi-cell synchronous testing adapter includes testing platforms for supporting cells arranged at intervals along a straight line on a base, and clamping seats arranged along the arrangement direction of each testing platform. The clamping seats are provided with clamping sections corresponding to the number and position of the testing platforms. Each clamping section is driven by a power source to synchronously clamp the cells on the testing platforms. A vertically lifting insulated lifting platform is installed on the base or clamping seats. The insulated lifting platform is arranged along the arrangement direction of the testing platforms. Pressure plates for connecting testing equipment are provided at intervals on the insulated lifting platform. Each pressure plate abuts against the tab of the corresponding cell to form a testing path.

[0006] The clamping action of multiple clamping sections automatically aligns each cell, achieving pre-clamping positioning. After clamping and positioning, the insulating lifting platform drives the pressure plates to rise and fall, thereby forming a detection path between the pressure plates and the cell electrode leads. The pressure plates are connected to various types of testing equipment, allowing each cell to be independently tested. This achieves synchronous automatic clamping and positioning testing of multiple cells, resulting in high testing efficiency.

[0007] As a further embodiment of this utility model: the clamping section of the clamping seat includes a coaxially arranged bidirectional lead screw, and both the forward and reverse rotation sections of the bidirectional lead screw are equipped with lead screw slides. Each lead screw slide is provided with a clamping plate. The two clamping plates on the bidirectional lead screw are symmetrically arranged on both sides of the testing table, and the two clamping plates cooperate to clamp and position the battery cell.

[0008] Multiple battery cells can be clamped simultaneously by coordinating the forward and reverse rotation sections of the bidirectional lead screw.

[0009] As a further improvement of this utility model, adjacent bidirectional lead screws are coaxially fixed together by a connecting shaft.

[0010] By coaxially fixing the bidirectional lead screw with the connecting shaft, quick assembly and disassembly can be achieved to adapt to clamping operations with different numbers of battery cells.

[0011] As a further improvement of this utility model: an auxiliary push plate is provided on the base along the direction parallel to the clamping seat. The auxiliary push plate is driven by a horizontal hydraulic rod to drive the auxiliary push plate to reciprocate linearly along the direction perpendicular to the clamping seat in order to push and position the battery cell.

[0012] The auxiliary pusher plate further improves the stability of the cell clamping process.

[0013] As a further embodiment of this utility model: the testing platform is arranged in an L-shaped plate configuration, with the vertical section of the testing platform and the clamping plates arranged perpendicularly to each other, and the horizontal section of the testing platform used to support the battery cell. The vertical section of the testing platform, the auxiliary push plate, and the two clamping plates work together to form a ring-shaped clamping and positioning of the battery cell.

[0014] The L-shaped design of the testing station enables a wraparound clamping and positioning of the battery cells, effectively improving the stability of the battery cell fixation.

[0015] As a further improvement of this utility model: each pressure plate is provided with an adapter, and a conductive post is provided axially inside the adapter. The adapter is connected to the plug of the testing equipment through the conductive post.

[0016] The adapter facilitates the connection of battery cells of different specifications with testing equipment.

[0017] As a further embodiment of this utility model: the pressure plate is arranged in an L-shaped plate manner, the vertical section of the pressure plate slides vertically with the vertical section of the testing table, and the horizontal section of the pressure plate abuts against the bottom of the battery cell from top to bottom to press the battery cell tightly.

[0018] The vertical sliding of the pressure plate facilitates clamping the battery cell from top to bottom, making subsequent testing easier.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model uses multiple sets of clamping sections on the clamping seat to clamp the battery cells, automatically centering each battery cell for pre-clamping and positioning. After clamping and positioning, the insulating lifting platform drives each pressure plate to rise and fall, thereby forming a detection path between the pressure plate and the battery cell electrode lead wire. The pressure plate is connected to various types of testing equipment, allowing each battery cell to be independently tested, achieving synchronous automatic clamping and positioning testing of multiple battery cells with high testing efficiency.

[0021] 2. The clamping section on the clamping seat of this utility model is set as a bidirectional lead screw. Through the forward and reverse rotation thread of the bidirectional lead screw, the lead screw slide on each bidirectional lead screw moves in opposite directions, thereby driving the two sets of clamping plates to move towards or away from each other, thereby clamping and positioning the battery cell. The multi-segment bidirectional lead screw is connected to each other by a connecting shaft, and can be arbitrarily disassembled and combined to adapt to the number of battery cells to be tested.

[0022] 3. This utility model can pre-push the battery cell into position by the linear push of the auxiliary push plate, which facilitates the initial positioning of the battery cell; the L-shaped layout of the testing table, the two sets of clamping plates on the bidirectional lead screw, and the auxiliary push plate and the vertical section of the testing table correspond to the four sides of the battery cell, forming a ring-shaped clamping and positioning of the battery cell.

[0023] 4. The adapters on the pressure plate of this utility model can be connected to the plugs of different testing equipment, making it easy to switch testing modes; the L-shaped design of the pressure plate can clamp and position the battery cell after it is raised and lowered with the insulating lifting platform.

[0031] Please see Figures 1-2 In this embodiment of the utility model, a multi-cell synchronous detection adapter includes a base 1, on which multiple sets of detection platforms 2 are arranged in parallel at intervals, each detection platform 2 being used to independently fix a set of cells.

[0032] The testing platform 2 is arranged in an L-shape. The horizontal section of the testing platform 2 is welded and positioned to the base 1, and the vertical section of the testing platform 2 is arranged perpendicular to the surface of the base 1. The battery cell is placed on the horizontal section of the testing platform 2 and supported by the testing platform 2.

[0033] The base 1 is also provided with a clamping seat 3 and an auxiliary push plate 5 arranged along the layout direction of the testing table 2. The clamping seat 3 is used to clamp and position the battery cell from the left and right, and the auxiliary push plate 5 is used to cooperate with the vertical section of the testing table 2 to clamp and position the battery cell from the front and back.

[0034] The clamping base 3 and the auxiliary push plate 5 are arranged in parallel, located on both sides of the vertical section of the testing table 2. The body of the auxiliary push plate 5 is arranged parallel to the vertical section of the testing table 2. A horizontal hydraulic rod is provided on the base 1, and the driving end of the horizontal hydraulic rod is connected to the auxiliary push plate 5, thereby pushing the auxiliary push plate 5 along the direction perpendicular to the vertical section of the testing table 2. Through the reciprocating linear motion of the auxiliary push plate 5, the auxiliary push plate 5 and the vertical section of the testing table 2 can clamp and fix the battery cell from front to back.

[0035] The clamping base 3 includes coaxially arranged multi-segment bidirectional lead screws 31. Each segment of the bidirectional lead screw 31 is coaxially fixed to the others via a connecting shaft 34. One set of bidirectional lead screws 31 at the end is coaxially fixed to the motor shaft of the lead screw motor, which synchronously drives each bidirectional lead screw 31 to rotate. Each bidirectional lead screw 31 includes a forward-rotating segment and a reverse-rotating segment with opposite helical directions. Both the forward-rotating and reverse-rotating segments are coaxially equipped with lead screw slides 32, which cooperate with the lead screws of the bidirectional lead screw 31, allowing them to travel linearly along the bidirectional lead screw 31 as it rotates. The two lead screw slides 32 on the bidirectional lead screw 31 move towards each other or away from each other at the same time. Clamping plates 33 are fixed on the lead screw slides 32, and these clamping plates 33 are arranged perpendicularly to the vertical section of the testing platform 2. The two clamping plates 33 on each bidirectional lead screw 31 cooperate to clamp and fix the battery cell from left to right.

[0036] The two sets of clamping plates 33 on the bidirectional lead screw 31, as well as the auxiliary push plate 5 and the vertical section of the detection table 2, correspond to the four sides of the battery cell, forming a ring-shaped clamping and positioning for the battery cell.

[0037] A vertically lifting insulated lifting platform 4 is also provided on the base 1. The insulated lifting platform 4 is driven to rise and fall by a vertical hydraulic rod on the base 1. The insulated lifting platform 4 is elongated and arranged parallel to the clamping seat 3. Pressure plates 43 are spaced apart on the insulated lifting platform 4. The number and position of the pressure plates 43 correspond to those of the testing table 2. The pressure plates 43 are arranged in an L-shape. The vertical section of the pressure plate 43 slides vertically with the vertical section of the testing table 2. The horizontal section of the pressure plate 43 abuts against the bottom of the battery cell from top to bottom to press the battery cell tightly. An adapter 41 is provided on the pressure plate 43. A conductive post 42 is arranged axially inside the adapter 41. The adapter 41 is plugged into the plug of the testing equipment through the conductive post 42. When the pressure plate 43 presses the tabs of the battery cell, the tabs are electrically connected to the testing equipment through the pressure plate 43 and the adapter 41, thereby completing different functional tests.
