Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a fixture for testing the charge and discharge of blade batteries. Background Technology

[0002] Blade battery, also known as blade-shaped lithium iron phosphate battery, is a specially designed lithium-ion battery. It is long and thin in shape and can be inserted into the battery pack like a "blade", hence the name. It uses lithium iron phosphate as the cathode material.

[0003] For charge and discharge testing of blade batteries, automated sorting equipment is generally used to fix and test the batteries. However, due to the complex structure and high cost of automated sorting equipment, it is not suitable for small and medium-sized enterprises (SMEs). SMEs with limited funds still rely on manual operation, using traditional tools such as screws and flathead screwdrivers to fix the blade batteries in place on the base before testing. However, manual operation is inefficient and prone to human error. Utility Model Content

[0025] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0026] like Figure 1 As shown in the figure, the fixture for charging and discharging testing of a blade battery provided in this embodiment of the present invention includes: a base 1, and a slide rail provided on the base 1. The base 1 is made of bakelite material, and the surface is frosted for anti-slip purposes.

[0027] Among them, such as Figures 3-4 As shown, the base 1 is provided with two clamping devices 3 for fixing the position of the blade battery. The clamping devices 3 are slidably connected to the base 1, and the clamping devices 3 are connected to probes 4 that contact the blade battery. A working platform 2 is also provided between the two clamping devices 3 for placing the blade battery.

[0028] Specifically, such as Figure 2 As shown, the working platform 2 includes a fixing plate 21, which is fixedly installed on the base 1. A buffer pad 22 is provided on the top of the fixing plate 21. The buffer pad 22 is made of a material with good cushioning performance, including but not limited to cotton and silicone. The buffer pad 22 can reduce pressure damage to the surface of the blade battery during the measurement process. In addition, an adjustable limit block (not shown in the figure) is provided at the edge of the working platform 2 to fix the position of the blade battery and prevent the battery from shifting.

[0029] like Figure 1 , Figures 3-4 As shown, two clamping devices 3 are provided, located on the left and right sides of the blade battery respectively. Each clamping device 3 includes a pressure plate 31, which is connected to a slider 34 via adjusting bolts. The slider 34 is embedded in a slide rail and slidably connected to the slide rail. The operator can manually move the pressure plate 31 to slide it horizontally left and right to accommodate the length of the blade battery. The pressure plate 31 has a through hole, within which a fixed sliding sleeve is installed. The sliding sleeve is fitted over the support rod 32, allowing the pressure plate 31 to slidably connect to the support rod 32.

[0030] A support plate 35 is fixedly mounted on the support rod 32. The support plate 35 is fixedly connected to the probe 4, and the probe 4 is electrically connected to an external measuring device via a wiring harness. A push plate 33 is also fixedly mounted on one end of the support rod 32.

[0031] like Figure 3 As shown, a quick clamp 6 is fixedly mounted on the push plate 33 of the clamping device 3 located on one side, and a slide 7 is fixedly mounted on the bottom of the quick clamp 6. Correspondingly, a slider 34 is also provided below the slide 7 and connected by adjusting bolts. The quick clamp 6 can push the push plate 33 to move towards the blade battery. The push plate 33 drives the support rod 32 to move, and the support rod 32 drives the support plate 35 to move. Under the action of the support plate 35, the probe 4 contacts the positive (or negative) terminal of the blade battery. It should be noted that the distance between the pressure plate 31 and the lower slider 34, and the distance between the slide 7 and the lower slider 34 can be adjusted to accommodate blade batteries of different heights or specifications.

[0032] like Figure 4 As shown, the support rod 32 in the clamping device 3 on the other side is fitted with a spring 8, which can make the corresponding probe 4 contact the negative (or positive) terminal of the blade battery under the elastic force of the spring 8.

[0033] It is understandable that probe 4 is silver-plated and has a travel of 5mm.

[0034] In this embodiment, the slide 7 is moved according to the length of the blade battery, the slider 34 is adjusted to a suitable position, the blade battery is placed on the buffer pad 22 on the work platform 2, and the operator manually moves the quick clamp 6 so that the probes 4 on both sides of the battery contact the positive and negative terminals to perform a charge and discharge test on the blade battery.

[0035] In this application, the clamping device 3 is manually adjusted to bring the probe 4 into contact with the positive and negative terminals of the blade battery, eliminating the need for motor drive in automated equipment. The use of a quick-release clamp 6 in conjunction with the clamping device 3 reduces costs and makes operation more intuitive. The fixture for blade battery charge / discharge testing has a simple overall structure, is easy to manufacture, and offers higher efficiency, accuracy, and error-free operation compared to manual operation using traditional tools. It allows for cost-effective control of blade battery testing, is suitable for smaller batch testing scenarios, ensures production quality, and is particularly suitable for small and medium-sized enterprises.

[0036] Working principle: Move the slide 7 according to the length of the blade battery, adjust the clamping device 3 to a suitable position on the working platform 2, place the blade battery on the buffer pad 22 on the working platform 2, and the operator manually moves the quick clamp 6 so that the probes 4 on both sides of the battery contact the positive and negative terminals to perform a charge and discharge test on the blade battery.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
