Description

Technical Field

[0001] The utility model belongs to the technical field of battery detection, and in particular relates to a go / no-go gauge for measuring the thickness of a battery. Background Art

[0002] Lithium-ion batteries have the advantages of high voltage, high specific energy, many cycles, and long storage time. They are widely used not only in portable electronic devices such as mobile phones, power banks, digital cameras, and laptops, but also in large and medium-sized electric devices such as electric vehicles, electric bicycles, and electric tools. Therefore, the performance requirements for lithium-ion batteries are getting higher and higher. Battery thickness is an important performance indicator. If the thickness exceeds the standard, it cannot be used. Therefore, before packing, the battery thickness needs to be sorted and tested one by one. How to quickly and accurately sort out the batteries that exceed the standard and sort the top thickness of the battery is an extremely important step.

[0003] On the other hand, the existing battery thickness measuring device structure generally includes a workbench for preventing batteries, a conveyor belt, and a screening mechanism for screening qualified batteries.

[0004] The Chinese utility model patent with patent announcement number CN201600105U and announcement date 2010.10.06 discloses a go / no-go gauge for detecting the thickness of parts. The structure includes an upper end face, a lower end face and a connecting face. The connecting face connects the upper end face and the lower end face. The upper end face and the lower end face are parallel to each other and are located on the same side of the connecting face. There is a boss in the upper end face, and the boss is located on the inner side of the upper end face.

[0005] The general structural principle of the go / no-go gauge in this utility model patent is as follows: the go / no-go gauge connects the upper end face and the lower end face through a connecting surface, and a boss is set in the upper end face. The distance from the upper end face to the lower end face and the distance from the boss to the lower end face are respectively the two limit values ​​of the allowable deviation of the thickness of the tested part, thereby suggesting whether the part thickness is qualified.

[0006] However, in actual use, the go / no-go gauge still has at least the following two shortcomings, in other words, which are the technical problems to be solved by the present utility model.

[0007] 1. The connection surface is connected to the boss, and the distance between the connection surface and the upper end surface is relatively close. The connection surface lacks an avoidance setting, which causes the battery parts to easily collide with the connection surface during measurement, causing damage and causing product risks.

[0008] 2. The qualified products can only show the qualified results when they hit the boss but cannot pass through, which will damage the workpiece.

[0009] So in summary, there is an urgent need for a new battery thickness go / no-go gauge that can avoid battery parts and screen out qualified batteries without impact. Utility Model Content

[0010] The utility model provides a go / no-go gauge for measuring the thickness of a battery, which can achieve the following by arranging a holding plate, an arc-shaped clearance plate unit, a fixed slotted plate unit and a protective elastic plate unit: 1. The upper limit of the battery thickness is controlled by the fixed slotted plate unit, and then the other structures of the battery are effectively avoided by the arc-shaped clearance plate unit to prevent scratches or damage to the battery; 2. The protective elastic plate unit prompts the lower limit of the battery thickness. When the size is obviously smaller than the qualified standard, the protective elastic plate unit protrudes more. When the size is obviously within the scope of the qualified standard, the protective elastic plate unit is forced to retract into the fixed slotted plate unit, so that qualified batteries can be screened out more accurately without impacting the battery.

[0011] The technical solution adopted by the utility model to solve the above-mentioned problem is: a go / no-go gauge for measuring the thickness of a battery, the structure comprising a holding plate, arc-shaped yielding plate units at both ends of which are respectively arranged on the holding plate and are used to protect the battery by protruding outward, fixed slotted plate units respectively arranged on the two holding plates and are used to detect the upper limit of the battery thickness by blocking, and a protective elastic plate unit arranged on the fixed slotted plate unit and is used to detect the lower limit of the battery thickness by retreating.

[0012] A further preferred technical solution is that the fixed slotted plate unit includes two stop plates, mounting slots arranged on the stop plates, and limit plates arranged on the mounting slots.

[0013] A further preferred technical solution is that the protective elastic plate unit includes a T-shaped telescopic plate arranged in the installation groove and used to detect the lower limit of the thickness of the battery, and a telescopic spring arranged in the installation groove and used to connect the T-shaped telescopic plate.

[0014] A further preferred technical solution is that the T-shaped telescopic plate is replaced by an L-shaped long plate, and further includes springs arranged at both ends of the L-shaped long plate.

[0015] A further preferred technical solution is that the protective elastic plate unit also includes limiting connecting plates arranged at both ends of the L-shaped long plate and used to connect the spring.

[0016] A further preferred technical solution is that the protective elastic plate unit also includes a fan-shaped guide plate arranged on the L-shaped long plate and used for the battery to move along the L-shaped long plate.

[0017] A further preferred technical solution is that the arc-shaped clearance plate unit includes an arc-shaped clearance plate.

[0018] A further preferred technical solution is that the arc-shaped clearance plate unit further includes an anti-slip plate arranged on the arc-shaped clearance plate.

[0019] A further preferred technical solution is that: a grip hole is provided on the grip plate.

[0020] A further preferred technical solution is that the protective elastic plate unit also includes a wear-resistant layer arranged on the fan-shaped guide plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0032] As attached Figure 1-6As shown, a go / no-go gauge for measuring the thickness of a battery comprises a holding plate 1, arc-shaped yielding plate units 2 at both ends of which are respectively arranged on the holding plate 1 and are used to protect the battery a by protruding outward, fixed slotted plate units 3 which are respectively arranged on the two holding plates 1 and are used to detect the upper limit of the thickness of the battery a by blocking, and a protective elastic plate unit 4 which is arranged on the fixed slotted plate unit 3 and is used to detect the lower limit of the thickness of the battery a by retreating.

[0033] In this embodiment, the go / no-go gauge for measuring the thickness of the battery is mainly used to screen batteries with qualified thickness. The user grabs the holding plate 1 for measurement, and the arc-shaped clearance plate unit 2 connects the two holding plates 1 and the fixed slotted plate unit 3 into a whole, thereby facilitating the thickness measurement operation. The arc-shaped clearance plate unit 2 is far away from the fixed slotted plate unit 3, and the battery a is reasonably avoided to prevent the battery a from being scratched during measurement and to avoid damage to the battery a.

[0034] In addition, the fixed slotted plate unit 3 is used to screen the upper limit of the battery thickness. The battery that cannot pass through the fixed slotted plate unit 3 indicates that the thickness is too large. By adjusting the distance between the two fixed slotted plate units 3, it is suitable for measuring different battery thicknesses. At the same time, the fixed slotted plate unit 3 is also used to install the protective elastic plate unit 4.

[0035] Finally. The protective elastic plate unit 4 is installed on the fixed slotted plate unit 3 to measure the lower limit of the battery a. When the thickness of the battery a is smaller than the thickness of the qualified battery, the protruding part of the protective elastic plate unit 4 is larger, and a more obvious color can be used for prompting, so as to facilitate the observation of the retreat of the protective elastic plate unit 4. When the thickness of the battery a is qualified, the protective elastic plate unit 4 will be pressed into the fixed slotted plate unit 3. Only the battery that meets the measurement requirements of the fixed slotted plate unit 3 and the protective elastic plate unit 4 at the same time will have a qualified thickness.

[0036] The fixed slotted plate unit 3 includes two stop plates 301 , a mounting slot 302 disposed on the stop plates 301 , and a limiting plate 303 disposed in the mounting slot 302 .

[0037] In this embodiment, the distance between the two stop plates 301 represents the upper limit of the thickness of the battery a, the mounting groove 302 is used to install the protective elastic plate unit 4, the depth of the mounting groove 302 can accommodate the required retreat distance of the protective elastic plate unit 4, and the limit plate 303 is used to clamp the protective elastic plate unit 4 to prevent it from falling off.

[0038] The protective elastic plate unit 4 includes a T-shaped telescopic plate 401 disposed in the mounting groove 302 and used to detect the lower limit of the thickness of the battery a, and a telescopic spring 402 disposed in the mounting groove 302 and used to connect the T-shaped telescopic plate 401 .

[0039] In this embodiment, the T-shaped telescopic plate 401 is stuck in the installation groove 302 by the limiting plate 303, and the telescopic spring 402 is used to reset the T-shaped telescopic plate 401, which reduces the resistance of the protective elastic plate unit 4 to a certain extent. When the thickness of the battery a is too small, the T-shaped telescopic plate 401 does not retreat or retreats into the installation groove 302 with a small amplitude, and the T-shaped telescopic plate 401 protrudes more obviously. When the thickness of the battery a is appropriate, the T-shaped telescopic plate 401 does not protrude obviously. In addition, in order to remind the user whether the thickness of the battery a is appropriate, a raised elastic ring can be set in the installation groove 302, and a friction block that cooperates with the elastic ring can be set on the T-shaped telescopic plate 401. When the T-shaped telescopic plate 401 retreats to a qualified position, the friction block passes over the elastic ring, and the user can judge whether the lower limit of the thickness of the battery a is qualified by the sound of the direct contact between the friction block and the elastic ring.

[0040] The T-shaped telescopic plate 401 is replaced by an L-shaped long plate 403 , and further includes springs 404 arranged at both ends of the L-shaped long plate 403 .

[0041] In this embodiment, the T-shaped telescopic plate 401 is replaced by the L-shaped long plate 403 to increase the contact area between the battery a and the L-shaped long plate 403 to facilitate measurement of the battery a. The spring 404 supports and resets the L-shaped long plate 403.

[0042] The protective elastic plate unit 4 further includes limiting connecting plates 405 which are arranged at both ends of the L-shaped long plate 403 and are used to connect the spring 404 .

[0043] In this embodiment, the limiting connecting plate 405 connects the L-shaped long plate 403 and the spring 404, and cooperates with the limiting plate 303 to make the structure more stable and prevent the L-shaped long plate 403 from falling off.

[0044] The protective elastic plate unit 4 further includes a fan-shaped guide plate 406 which is arranged on the L-shaped long plate 403 and is used for the battery a to move along the L-shaped long plate 403 .

[0045] In this embodiment, when measuring the thickness of the battery a, since the protective elastic plate unit 4 is protruding, when the thickness of the battery a is close to the upper limit of the tolerance, it is more difficult for the battery a to squeeze the protective elastic plate unit 4, and it is easy to scratch the blue film of the battery a. The function of the fan-shaped guide plate 406 is to guide the battery a to move along the L-shaped long plate 403, thereby reducing the difficulty of the battery a squeezing the L-shaped long plate 403.

[0046] The arc-shaped clearance plate unit 2 includes an arc-shaped clearance plate 201 .

[0047] In this embodiment, the arc-shaped clearance plate 201 is used to effectively avoid the battery a to prevent the arc-shaped clearance plate 201 from interfering with the battery a and causing damage to the battery a. The arc-shaped clearance plate 201 can be an arc or other protruding setting form to avoid interfering with the battery a.

[0048] The arc-shaped clearance plate unit 2 further includes an anti-slip plate 202 arranged on the arc-shaped clearance plate 201 .

[0049] In this embodiment, the anti-slip plate 202 has a function of increasing the friction between the hand and the arc-shaped clearance plate 201 when the user grabs the arc-shaped clearance plate 201 to perform measurement work.

[0050] The gripping plate 1 is provided with a gripping hole 5 .

[0051] In this embodiment, the grip hole 5 serves to facilitate the user to grasp and use the go / no-go gauge, and the size of the grip hole 5 is suitable for the gripping size of a normal adult.

[0052] The protective elastic plate unit 4 further includes a wear-resistant layer 407 disposed on the fan-shaped guide plate 406 .

[0053] In this embodiment, the function of the wear-resistant layer 407 is to reduce the resistance and friction of the fan-shaped guide plate 406 on the battery a, reduce the wear on the battery a, and reduce the difficulty of the battery a sliding into the L-shaped long plate 403, thereby achieving a better use effect.

[0054] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
