Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, specifically to a loading and unloading platform suitable for airtightness testing of battery frames. Background Technology

[0002] With the widespread use of electronic devices and the increasing demand for portable power supplies, batteries have been widely used as energy storage devices. Battery frame airtightness testing is a crucial step in the battery manufacturing process. Its main purpose is to ensure the sealing performance of the battery frame, preventing external air, moisture, or dust from entering the battery, thereby protecting the safety and stability of the internal components.

[0003] The specific method for testing the airtightness of the battery frame is as follows: First, place the battery frame on the testing platform, and then press the upper end of the battery frame tightly with a lifting and lowering pressure plate to form a sealed space inside the battery frame. Finally, pressurize or fill the sealed space with gas. If there is a leak, the gas will gradually leak out from the leak, causing the internal pressure to drop. Therefore, by detecting the change in internal pressure of the sealed space, it can be determined whether the battery frame is sealed properly.

[0004] In existing technologies, the battery frame is heavy, and the pressure plate above the testing platform makes installation time-consuming and labor-intensive, resulting in low efficiency. Furthermore, during testing, inflating or pressurizing the battery frame causes it to shift laterally, making it difficult to maintain a proper seal between the pressure plate and the frame, leading to poor airtightness and affecting the test results. Utility Model Content

[0005] In view of this, the present invention provides a loading and unloading platform suitable for testing the airtightness of battery frames, the purpose of which is to solve the technical problems pointed out in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A loading and unloading platform for testing the airtightness of battery frames includes a base. At least two sets of slide rails are arranged in parallel on the base. A testing platform is slidably mounted on the slide rails via a linear module. The testing platform is used to fix the battery frame to be tested. The left and right halves of the slide rails are defined as a testing working area and a loading and unloading area, respectively. Limiting mechanisms and locking mechanisms are respectively provided at both ends of the corresponding testing working areas on the base.

[0008] When the testing platform is slid from the loading and unloading area into the testing work area, one end of the battery frame to be tested on the testing platform abuts against the limiting mechanism, and the other end is fixed by the locking mechanism.

[0009] Using the above structure, the frame to be tested is fixed on the testing table, and the battery frame is pushed in electrically, eliminating the need for manual labor and increasing efficiency. The testing work area is equipped with limiting and locking mechanisms at both ends of the testing table, which can prevent the battery frame from shifting laterally and causing poor airtightness, thus obtaining an accurate testing structure.

[0010] Preferably, the locking mechanism includes a locking component and a driving device. The lower end of the locking component is connected to the driving device, and the upper end is provided with a locking part. The driving device is used to drive the locking component to rotate upward so that the locking part abuts against the side of the testing table. This structure is simple and easy to install.

[0011] Preferably, a first extension member is fixedly connected to the side of the locking part near the testing table, and the first extension member is used to extend the locking part along the height direction. This structure is adaptable to various testing devices.

[0012] Preferably, a second extension member is fixedly connected to the side of the locking part near the testing table, and the second extension member is used to extend the locking part along the width direction. This structure is adaptable to various testing devices.

[0013] Preferably, the second extension component can be stacked on top of the first extension component. This structure is adaptable to various detection devices.

[0014] Preferably, the limiting mechanism includes a limiting component and a supporting spring. After the detection table is pushed into the detection working area, both the limiting component and the supporting spring abut against the side of the detection table, and the supporting spring is in a compressed state. Using the above structure, in conjunction with the locking mechanism, the detection table is fixed to prevent lateral displacement.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The present invention provides a loading and unloading platform suitable for testing the airtightness of battery frames. The battery frame to be tested is fixed on the testing platform, which is mounted on a slide rail. The slide rail has a loading and unloading area that is unobstructed and convenient for loading and unloading. The testing platform is connected to a linear module, eliminating the need for manual labor and increasing work efficiency.

[0017] 2. When the testing platform slides from the loading and unloading area into the testing work area, the limiting mechanism and locking mechanism set on the base at both ends of the testing work area can lock the testing platform to prevent it from shifting to the side and affecting the testing results.

[0022] Figure 5 This is a schematic diagram to illustrate the structure of the limiting mechanism B. Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, a loading and unloading platform suitable for testing the airtightness of battery frames includes a base. Two sets of slide rails 2 are arranged parallel to each other at both ends of the base. A testing platform 1 for fixing the battery frame to be tested is slidably mounted on the slide rails 2 via a linear module. Figure 1 As shown in the direction reference, the left half and right half of the slide rail 2 are defined as the detection work area 21 and the loading and unloading area 22, respectively. A detection device is provided above the detection work area 21 for detecting the airtightness of the battery frame.

[0025] like Figure 1 As shown, the substrate has two limiting mechanisms B and a locking mechanism A at each end of the corresponding detection working area 21, respectively. Both limiting mechanisms B and locking mechanisms A are located between the two sets of slide rails 2 at both ends. Extensions 11 that cooperate with the limiting mechanisms B and locking mechanisms A are provided on the lower sides of both ends of the detection table 1. Figure 3 As shown, the locking mechanism A includes a locking component 3 and a driving device 4. The lower end of the locking component 3 includes two connecting arms 32, the inner sides of which are connected to the driving device 4. A locking part 31 is provided at the lower end. The driving device 4 can drive the locking component 3 to rotate. Figure 4 As shown, under normal conditions, the locking component 3 is horizontally positioned below the slide rail 2. After the inspection table 1 is slid into the inspection work area 21 from the loading and unloading area 22, the driving device 4 drives the locking component 3 to rotate upward so that the locking part 31 abuts against the side of the inspection table 1.

[0026] like Figure 5 As shown, the limiting mechanism B includes a limiting component 7 and a supporting spring 8. The limiting component 7 is block-shaped and is fixed on the base in an up-down distribution with the supporting spring 8. When the detection table 1 is pushed into the detection working area 21, the extension 11 abuts against the limiting component 7, and the side of the detection table 1 abuts against the supporting spring 8. At this time, under the action of the locking mechanism A, the supporting spring 8 is in a compressed state.

[0027] like Figure 3As shown, the locking part 31 can be fixed to the first extension part 5 and the second extension part 6 on the side near the frame base 1. The locking part 3 can be extended along the height and width directions respectively. The first extension part 5 is T-shaped and its vertical end is fixed to the locking part 31. The second extension part 6 is rectangular and can be connected to the locking part 31 alone or superimposed on the horizontal end of the first extension part 5, so that the locking mechanism A can be applied to situations where the distance between the detection table 1 and the base is far.

[0028] like Figure 1 As shown, during the battery frame airtightness test, the battery frame is fixedly mounted on the testing table 1 in the loading / unloading area 22 and pushed into the testing work area 21. A limiting mechanism B is provided at the left end of the testing work area 21. The extension 11 at the bottom of the testing table 1 abuts against the limiting component 7, and the side of the testing table 1 abuts against the support spring 8. Figure 3 As shown, a locking mechanism A is provided at the right end of the testing work area 21. The driving device 4 drives the locking component 3 to rotate upward. In this embodiment, the locking component 3 is fixedly connected to the first extension component and the second extension component 6. The second extension component 6 abuts against the extension 11 at the bottom of the testing table 1, as shown. Figure 5 As shown, under the action of locking mechanism A, the support spring is compressed, and both ends of the testing table 1 are fixed. During testing, the testing table 1 cannot move laterally, thus obtaining an accurate test result. After the test is completed, the linear module pushes the testing table 1 to the loading and unloading area 22 for unloading.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
