Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and in particular to a new energy soft-pack battery clamping and positioning device. Background Technology

[0002] As a key component in the new energy field, the performance of pouch batteries directly affects the user experience and reliability of electronic devices and electric vehicles. Therefore, after the production of pouch batteries, they must undergo rigorous testing to ensure that their performance meets design requirements.

[0003] New energy soft-pack batteries are often tested in batches, with a series of batteries being tested sequentially. During testing, test wires are connected to the tabs of the new energy soft-pack batteries and the test results are output. The performance of the new energy soft-pack batteries is then assessed by analyzing the test results.

[0004] When testing a range of new energy soft-pack batteries, clamps are often used to hold the batteries in order to protect the battery cells, stabilize the battery status, improve testing accuracy, and ensure the safety of the testing process.

[0005] During testing of new energy batteries, it is necessary to ensure that the position of the new energy battery and the fixture is relatively fixed. The existing testing process relies on the tester's manual placement and visual judgment to determine whether the pouch battery is in the center of the fixture. The testing process is highly subjective and it is difficult to ensure that a series of pouch batteries are all in the center of the fixture. Utility Model Content

[0006] One objective of this invention is to solve the problem that existing tests for new energy soft-pack batteries cannot guarantee that the battery is centered in the fixture.

[0007] Specifically, embodiments of this application provide a positioning device for a new energy soft-pack battery clamp, comprising:

[0008] Clamping fixtures are used to clamp the upper and lower surfaces of the main body of the pouch battery and expose the tabs on both sides of the pouch battery.

[0009] The positioning block has a first fixing groove for defining the clamping plate fixture and two second fixing grooves for defining the tabs of the soft-pack battery. The first fixing groove is adapted to the clamping plate fixture, and the second fixing grooves are adapted to the tabs. The two second fixing grooves are symmetrically arranged in the middle of both sides of the first fixing groove along a first direction and communicate with the first fixing groove. The two second fixing grooves pass through the positioning block along the first direction.

[0010] Furthermore, the positioning block has a first cut through a third direction on one side along the second direction, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0011] Furthermore, the positioning block is provided with a second cut through the third direction on the other side of the second direction, and the first cut and the second cut are symmetrically arranged along the second direction.

[0012] Furthermore, the first cut and the second cut extend into the first fixing groove.

[0013] Furthermore, a first buffer pad is provided at the bottom of the first fixing groove.

[0014] Furthermore, the clamping fixture includes a first clamping plate and a second clamping plate, which are connected and clamped together by a connector.

[0015] Furthermore, the connector is a bolt fixed to the first clamping plate, and the second clamping plate is provided with a through hole, through which the bolt passes.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting a first fixing groove and a second fixing groove in the positioning block, and making the second fixing groove located at the center of the first fixing groove in the first direction, it is ensured that the clamp holding the new energy soft pack battery is placed in the first fixing groove and the second fixing groove, and the new energy soft pack battery is located at the center of the clamp.

[0018] 2. Cutouts penetrating the third direction of the positioning block are provided on both sides of the positioning block in the second direction, so that the operator can easily remove the clamping plate fixture from the first fixing groove and improve the detection efficiency.

[0019] 3. By setting a first buffer pad at the bottom of the first fixed groove, the new energy soft pack battery is prevented from being damaged when the operator places the clamp with the new energy soft pack battery in the first fixed groove. Attached Figure Description

Detailed Implementation

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0026] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] The positioning device for a new energy soft-pack battery clamp of this utility model includes a clamping plate 1 and a positioning block 2. For example... Figure 3 As shown, the clamping fixture 1 is used to clamp the upper and lower surfaces of the main body 31 of the new energy soft-pack battery 3, exposing the tabs 32 on both sides of the new energy soft-pack battery 3. Figure 1 or Figure 2 As shown, the positioning block 2 has a first fixing groove 4 for limiting the clamping plate 1 and two second fixing grooves 5 for limiting the tabs 32 of the new energy soft pack battery 3. The first fixing groove 4 is adapted to the clamping plate 1, and the second fixing grooves 5 are adapted to the tabs 32. The two second fixing grooves 5 are symmetrically arranged in the middle of both sides of the first fixing groove 4 along the first direction (direction a in the figure) and are connected to the first fixing groove 4. The two second fixing grooves 5 pass through the positioning block 2 along the first direction.

[0029] The clamping fixture 1 holds the main body 31 of the new energy soft-pack battery 3, exposing the tabs 32 at both ends. The clamping fixture 1 is confined in the first fixing groove 4. When the tabs 32 are confined in the second fixing groove 5, since the second fixing groove 5 is located in the middle of both sides of the first fixing groove 4, the new energy soft-pack battery 3 is precisely positioned in the middle of the clamping fixture 1, meeting the testing requirements. This new energy soft-pack battery clamping positioning device provides an objective basis for operators to clamp the new energy soft-pack battery 3 using the clamping fixture 1, avoiding uncertainties caused by visual observation.

[0030] In one embodiment, the positioning block 2 has a first cut 6 extending through the third direction (direction c in the figure) on one side along the second direction (direction b in the figure). The first direction, the second direction, and the third direction are perpendicular to each other. Because the size of the first fixing groove 4 matches the size of the clamping plate 1, the gap between the edge of the first fixing groove 4 and the clamping plate 1 is small. After the testing operation is completed, it is inconvenient for the operator to remove the clamping plate 1. A thin plate needs to be inserted into the gap between the first fixing groove 4 and the clamping plate 1 to pry it out. Although the operator can remove the clamping plate 1 by pulling the tab 32, the overall weight of the clamping plate 1 is relatively heavy. When the operator pulls the tab 32 to lift the clamping plate 1, it will damage the connection between the tab 32 and the main body 31, resulting in an unreliable connection between the tab 32 and the main body 31, leading to poor contact during subsequent testing. By providing a first cut 6 through the third direction on one side of the positioning block 2 along the second direction, the operator can directly remove the clamping fixture 1 from the cut, facilitating operation. When there are many new energy soft-pack batteries 3 to be inspected, the first cut 6 can significantly improve the operator's inspection efficiency.

[0031] In another embodiment, a second cut 7 penetrating the third direction is provided on the other side of the positioning block 2 along the second direction, and the first cut 6 and the second cut 7 are symmetrically arranged along the second direction. When sequentially testing a series of new energy soft-pack batteries 3, multiple clamping fixtures 1 need to be placed in multiple positioning blocks 2, and the operator stands on one side of the operating table to perform the testing. By providing cuts on both sides of the positioning block 2, the operator can easily remove the clamping fixtures 1 from either side of the positioning block 2 without adjusting the placement position of the positioning block 2, which facilitates the operator's testing operation and improves testing efficiency.

[0032] Furthermore, in the positioning device for the new energy soft-pack battery clamp of this utility model, the first cut 6 and the second cut 7 extend into the first fixing groove 4. Through the above arrangement, on the one hand, the cut is large enough to facilitate the operator to remove the clamping plate clamp 1, and on the other hand, the material used for the positioning block 2 is saved to the maximum extent, reducing the production cost of the positioning block 2.

[0033] In one embodiment, a first buffer pad (not shown) is provided at the bottom of the first fixing groove 4. Since the clamping plate 1 and positioning block 2 are relatively hard, while the new energy soft-pack battery 3 is relatively soft, when operators test a series of new energy soft-pack batteries 3, they often operate quickly to improve testing efficiency, making it difficult to handle them gently. This could easily damage the new energy soft-pack battery 3, affecting the accuracy of the test data. By providing a first buffer pad at the bottom of the first fixing groove 4, the clamping plate 1 with the new energy soft-pack battery 3 is cushioned when placed in the first fixing groove 4, preventing damage to the new energy soft-pack battery 3 due to improper operation during testing.

[0034] In the positioning device for new energy soft-pack batteries of this utility model, the clamping fixture 1 includes a first clamping plate 11 and a second clamping plate 12, which are connected and clamped together by a connector 13. In one embodiment, the connector 13 is a buckle, which is used to fix and clamp the first clamping plate 11 and the second clamping plate 12.

[0035] In another embodiment, the connector 13 is a bolt 131 fixed to the first clamping plate 11, and the second clamping plate 12 has a through hole through which the bolt 131 passes. In specific operation, the first clamping plate 11 is first placed in the first fixing groove 4 with the bolt 131 facing upwards. Then, the new energy soft-pack battery 3 is placed on the first clamping plate 11, the through hole on the second clamping plate 12 is engaged with the bolt, and the nut 132 is tightened to a suitable position. By using the bolt 131 as the connector 13, the clamping force for different new energy soft-pack batteries 3 can be determined by the tightness of the nut 132, allowing the clamping fixture 1 to be used to clamp new energy soft-pack batteries 3 of different thicknesses, thus enhancing the applicability of the clamping fixture 1.

[0036] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
