Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for lithium battery production, and more specifically, to a tooling for measuring lithium batteries. Background Technology

[0002] Lithium-ion batteries mainly consist of a casing, a core, and an electrolyte, with the casing mostly made of aluminum. The lithium-ion battery is connected to the outside world through positive and negative electrodes. During the production process, it is necessary to measure the packaged batteries to detect short circuits, typically using a multimeter.

[0003] Currently, the common operating method on production lines involves operators holding two probes of a multimeter and connecting them to the positive and negative terminals of the battery for measurement. During this process, the operator needs to hold both probes with both hands, using the metal parts of the probes to contact the positive and negative terminals. When using both hands to hold the probes, for the same type of battery, this can easily lead to inaccurate measurement results. Furthermore, using both hands also occupies both hands, preventing other operations from being performed. Utility Model Content

[0004] To address at least some of the problems in the prior art, this utility model provides a tooling for measuring lithium batteries, solving the problem that when detecting internal short circuits in batteries, it is necessary to use both hands to hold the measuring pen for measurement.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A tooling for measuring lithium batteries, comprising:

[0007] A crossbar is provided with a gripping portion and at least two clamping connecting portions along its length extension direction.

[0027] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0028] The terms “installation,” “setup,” “equipped with,” and “connection” used herein should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0029] When testing for internal short circuits in lithium batteries during production, a multimeter is used. The operator holds the multimeter's two probes with both hands, contacting them with the positive and negative terminals of the battery to take the measurement. In this situation, both of the operator's hands are occupied, making it impossible to perform other auxiliary tasks, such as recording or marking. Figure 1 As shown, this embodiment provides a fixture for measuring lithium batteries, which allows operators to operate two measuring pens with only one hand for measurement.

[0030] The lithium battery measuring fixture in this embodiment includes a crossbar 6 and a clamping assembly.

[0031] The crossbar 6 has a gripping part and two clamping connecting parts along its length, with the clamping connecting parts located on both sides of the gripping part. There are two clamping assemblies, the number of which corresponds to the number of clamping connecting parts. Each clamping assembly includes a clamping body 2, which includes an upper clamping part and a lower clamping part 11 connected together. The upper clamping part is connected to the clamping connecting parts on the crossbar 6, and the lower clamping part 11 is used to clamp the measuring pen used for measurement.

[0032] During measurement, the operator lifts the entire fixture by gripping the handle of the crossbar 6 with one hand. The measuring pens held by the two lower clamps 11 contact the positive and negative terminals of the battery respectively for measurement. This process allows the operator to complete the measurement with only one hand, freeing up the other hand for other tasks. Furthermore, the measurement process using this fixture is more stable, avoiding inaccurate results caused by operator hand tremors.

[0033] It should be noted that the directional terms "up" and "down" described in this embodiment are based on Figure 1 The orientation of the center view is described.

[0034] In other cases, the clamping connection on the crossbar 6 can also be located on the same side as the gripping part, and the clamping connection can also be set to two or more other quantities.

[0035] A handle 4 is also connected to the gripping part of the crossbar 6. The handle 4 can be rod-shaped, with one end connected to the crossbar 6; or it can be semi-circular, with both ends connected to the crossbar 6. In other cases, the handle 4 can also be other shapes, which are not limited in this embodiment. The handle 4 is provided to facilitate the operator's gripping of the tooling and to increase the operator's working range. With the help of the handle, the tooling can be extended to a greater distance during measurement, thereby expanding the working range.

[0036] Combination Figure 2 , Figure 5 and Figure 6 As shown, a first clamping groove 9 is formed on the lower clamping part 11, and an adjustable locking member 7 is connected to one side wall of the first clamping groove 9. Specifically, a first threaded hole 14 is formed on one outer wall of the first clamping groove 9, which communicates with the first clamping groove 9. The locking member 7 is screwed into the first threaded hole 14, and one end of the locking member 7 is located in the first clamping groove 9. During measurement, the measuring pen is located in the first clamping groove 9, and the locking member 7 clamps and locks the measuring pen.

[0037] In a preferred embodiment, the locking member 7 has an elastic anti-slip sleeve 8 at one end that contacts the measuring pen, and an elastic anti-slip pad 10 is provided on the other side wall of the first clamping groove 9. Specifically, the anti-slip pad 10 is located on the other side wall of the first clamping groove 9 without the first threaded hole 14. The anti-slip pad 10 is made of elastic material. When the lower clamping part 11 clamps the measuring pen, the anti-slip pad 10 contacts the measuring pen, and the deformation of the anti-slip pad 10 increases the friction force on the measuring pen, which helps to prevent the measuring pen from slipping out of the first clamping groove 9. The locking member 7 has an anti-slip sleeve 8 at one end in the first clamping groove 9. The anti-slip sleeve 8 is also made of elastic material, and it completely covers the end of the locking member 7. When the lower clamping part 11 clamps the measuring pen, the anti-slip sleeve 8 contacts the measuring pen, and the deformation of the anti-slip sleeve 8 increases the contact area between the measuring pen and the tooling, which helps to prevent the measuring pen from slipping out of the first clamping groove 9. On the other hand, when the lower clamping part 11 clamps the measuring pen, the anti-slip sleeve 8 and the anti-slip pad 10 are located on both sides of the measuring pen. Both the anti-slip sleeve 8 and the anti-slip pad 10 are elastic, which can prevent the measuring pen from falling off, and also increase the locking redundancy of the locking part 7 when adjusting and locking the measuring pen, so as to avoid damage to the measuring pen due to excessive tightening.

[0038] In this embodiment, the upper clamping part of the clamping body 2 is slidably connected to the crossbar 6; a second clamping groove 13 is formed on the upper clamping part, and the second clamping groove 13 is engaged with the clamping connection part of the crossbar 6. Figure 3 As shown, an anti-slip groove 5 extending along the length of the crossbar 6 is provided. One side wall of the second clamping groove 13 is connected to a positioning member 3, one end of which extends into the anti-slip groove 5 for positioning and pressing the clamping body 2. Specifically, a second threaded hole 15 is provided on the upper outer wall of the second clamping groove 13, and the positioning member 3 is threadedly connected in the second threaded hole 15.

[0039] In use, the crossbar 6 passes through the second clamping slots 13 of the two clamping components. The positioning element 3 is rotated to fix the two clamping components onto the crossbar 6. Then, the two measuring pens are placed in the two first clamping slots 9 respectively. Rotating the locking element 7 achieves the purpose of clamping and fixing the measuring pens through the two lower clamping parts 11, allowing the user to hold both measuring pens with one hand without them wobbling. Rotating to release the positioning element 3 allows the clamping body 2 to move on the crossbar 6, thereby adjusting the distance between the two clamping bodies 2 on the crossbar 6, and thus adjusting the distance between the two measuring pens to accommodate more electrode spacings and improve the versatility of the device.

[0040] Furthermore, the positioning component 3 is a wing screw, which is more convenient to operate than a hexagonal screw.

[0041] Combination Figure 1 and Figure 4As shown, stoppers 1 are respectively provided at both ends of the anti-slip groove 5. Locking holes 12 are provided at both ends of the crossbar 6. A threaded rod is provided on the stopper 1, and the locking hole 12 is threadedly connected to the stopper 1. The upper surface of the stopper 1 is higher than the upper surface of the crossbar 6, or the lower surface of the stopper 1 is lower than the lower surface of the crossbar 6. In use, when the positioning piece 3 is loosened and the position of the clamping body 2 is adjusted left and right on the crossbar 6, the tightened stopper can prevent the clamping body 2 from slipping off the crossbar 6.

[0042] In this embodiment, the upper clamping part and the lower clamping part 11 are an integral structure, which simplifies the manufacturing method of the clamping body 2.

[0043] The tooling in this embodiment integrates the measuring pen with the tooling, allowing the operator to perform tests by holding the crossbar 6 with one hand and contacting the battery electrode with the test end of the measuring pen.

[0044] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
