Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and particularly relates to a self-locking restraint tray tooling. Background Art

[0002] During the production process of battery cells, a high-temperature charge-discharge process is often required to test the charge-discharge quality of the produced battery cells. This process requires putting the produced battery cells into a restraint tray for extrusion, so that the battery cells are in an extruded state for the charge-discharge experiment.

[0003] In the prior art, most restraint trays for extruding battery cells often extrude the overall length of multiple battery cells and separators to a set value through an extrusion mechanism, and then insert equal-thickness restraint blocks into the tray frame for restraint, so that the battery cells are kept in an extruded state for the charge-discharge experiment. Since the thicknesses of different types of battery cells are not the same, they may be too wide or too thin, so this restraint method is likely to cause too high or too low extrusion pressure when extruding the battery cells, thus affecting the charge-discharge quality of the battery cells.

[0035] Embodiment 1:

[0036] This embodiment provides a self-locking restraint tray tooling, including:

[0037] A frame 1, on which a limiting member 2 is provided;

[0038] A plurality of partition assemblies 3, which are movably arranged in the frame 1 along the first direction X, and the cells to be extruded are placed between two adjacent partition assemblies 3;

[0039] An extrusion mechanism, the extrusion mechanism includes a pressing plate 4 and a first driving member, the pressing plate 4 is movably arranged in the frame 1 along the first direction X, and the first driving member is arranged outside the frame 1 for driving the pressing plate 4 to move along the first direction X;

[0040] Self-locking mechanism, the self-locking mechanism is installed on the pressing plate 4 and includes a positioning member 5 that can telescopically move along the second direction Y. The positioning member 5 is used for clamping and fixing with the limiting member 2.

[0041] Unlocking mechanism, the unlocking mechanism includes a push block 6 and a second driving member. The push block 6 is movably arranged in the frame 1 along the first direction X. The second driving member is arranged outside the frame 1 and is used to drive the push block 6 to move along the first direction X so that the positioning member 5 approaches or moves away from the limiting member 2.

[0042] In this technical solution, as Figure 1 、 Figure 2 shown, a plurality of partition assemblies 3 are arranged in the frame 1. The cavities formed between two adjacent partition assemblies 3 are used to place the cells to be extruded. The pressing plate 4 is arranged in the frame 1 and is located on one side of the partition assemblies 3 as a whole along the first direction X. Further, the positioning member 5 is a toothed block, and the limiting member 2 is a rack. The toothed block is connected to the pressing plate 4, and the toothed block meshes and clamps with the rack, so that the pressing plate 4 is in a locked state and cannot move along the first direction X.

[0043] When this tray tooling works, several cells to be extruded are respectively placed in each cavity. The second driving member (not shown in the attached drawings of the specification) arranged outside the frame 1 is started first. The second driving member is used to control the push block 6 to move along the first direction X. The push block 6 contacts the toothed block and pushes the toothed block to move along the second direction Y. The gear is separated from the rack, so that the locking of the pressing plate 4 is released. Then the first driving member (not shown in the attached drawings of the specification) drives the pressing plate 4 to move along the first direction X to push the partition assembly 3 to extrude the cells. When the extrusion pressure reaches the set value, the second driving member controls the push block 6 to retract, so that the toothed block resets and is clamped and fixed with the rack on the frame body, so that the pressing plate 4 remains fixed in the frame 1 and cannot move, so that the cells can perform the charge and discharge function experiment under the extrusion state.

[0044] After the experiment is completed, the second driving member controls the push block 6 to move along the first direction X again. The push block 6 pushes the positioning member 5 to separate from the limiting member 2, so that the clamping and fixing between the positioning member 5 and the limiting member 2 is released. Then the first driving member controls the pressing plate 4 to retract along the first direction X and move away from the partition assembly 3.

[0045] In summary, the pressing plate 4 of this tray tooling is provided with a self-locking mechanism. When the pressure applied by the pressing plate 4 to the cells reaches the set value, the positioning member 5 of the self-locking mechanism is clamped and fixed with the limiting member 2 on the frame 1, so that the pressing plate 4 is fixed on the frame 1 and no longer moves, so as to ensure that each charge and discharge function experiment of the cells is carried out under an equal-pressure state, ensuring the accuracy of the experiment.

[0046] Embodiment 2:

[0047] This embodiment provides a self-locking restraint tray tooling. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0048] Further, the self-locking mechanism further includes:

[0049] A fixed seat 7, which is detachably mounted on the pressing plate 4, and a positioning member 5 is movably mounted on the fixed seat 7 along the second direction Y;

[0050] A telescopic assembly, which is telescopically mounted between the positioning member 5 and the fixed seat 7 along the second direction Y.

[0051] In this technical solution, the fixed seat 7 is mounted on the pressing plate 4 by setting fasteners. A groove is provided in the fixed seat 7. The positioning member 5 is movably arranged in the groove along the second direction Y. A telescopic assembly is installed in the groove to control the movement of the positioning member 5 in the second direction Y.

[0052] Further, the telescopic assembly includes:

[0053] A positioning rod 8, which is mounted on the fixed seat 7;

[0054] An elastic member 9, which is sleeved on the positioning rod 8 and axially abuts against the positioning member 5 and the fixed seat 7.

[0055] The elastic member 9 can be a spring. The spring is sleeved on the positioning rod 8 and axially abuts against the positioning member 5 and the side wall of the groove. When the push block 6 pushes the positioning member 5 to separate from the limiting member 2, the self-locking of the pressing plate 4 is released. At the same time, the positioning member 5 squeezes the spring, and the spring deforms. After the push block 6 retracts, the spring resumes its original shape and pushes the positioning member 5 to engage with the limiting member 2 again, so as to realize the self-locking and fixing of the pressing plate 4 in the frame 1.

[0056] Embodiment 3:

[0057] This embodiment provides a self-locking restraint tray tooling, which, in addition to including the technical solutions of the above embodiments, further has the following technical features.

[0058] Further, the self-locking mechanism further includes:

[0059] An abutting member 10, which is detachably mounted on the positioning member 5 and is used for abutting against the push block 6.

[0060] Further, the push block 6 is provided with an inclined surface structure for contacting the abutting member 10.

[0061] In this technical solution, the first driving member drives the push block 6 to move along the first direction X. The inclined surface of the push block 6 contacts the abutting member 10. In the process of the push block 6 moving along the first direction X and approaching the pressing plate 4, the abutting member 10 moves relatively along the inclined surface, thereby driving the positioning member 5 to move along the second direction Y, so that the positioning member 5 separates from the limiting member 2, and the self-locking of the pressing plate 4 is released.

[0062] Further, the abutting member 10 is a pin. An installation hole is formed in the positioning member 5, and the abutting member 10 can be a pin inserted and fixed in the installation hole of the positioning member 5, which is convenient for disassembly and assembly and helps with replacement and maintenance.

[0065] Further, the pressing mechanism further includes:

[0066] A pressing block 11, the pressing block 11 is connected to the driving end of the first driving member, and a sliding groove 12 is provided on the pressing block 11;

[0067] A connecting block 13, the connecting block 13 is installed on the pressing plate 4, and a clamping portion 14 is provided on the connecting block 13;

[0068] Wherein, the clamping portion 14 is movably arranged in the sliding groove 12 along the first direction X.

[0069] In this technical solution, as Figure 2 shown, when the first driving member controls the pressing block 11 to move along the first direction X, after the pressing block 11 abuts against the connecting block 13, the pressing plate 4 is pushed to move through the connecting block 13, so as to realize the pressing of the pressing plate 4 on the battery cell. When the first driving member controls the pressing block 11 to retreat along the first direction X, the clamping portion 14 abuts against the end of the sliding groove 12, so that the clamping portion 14 of the pressing block 11 and the connecting block 13 are clamped and fixed. Thus, when the first driving member controls the pressing block 11 to retreat, the pressing plate 4 can be pulled back to its original position by the way, without manual operation to reset the pressing plate 4, which is practical and convenient.
