Description

Technical Field

[0001] The present invention relates to the technical field of battery processing, and in particular to a battery external dimension measuring device and a measuring method. Background Art

[0002] During the battery pack production process, the dimensions of the packaged battery packs need to be measured to ensure that the specifications of the battery packs meet the production requirements, so as to avoid the battery packs not meeting the requirements and causing malfunctions. Currently, the dimensions of battery packs are mostly measured manually using a manual jig, but this measurement method has certain errors.

[0003] For example, the utility model patent with publication number CN217358442U discloses a device for measuring the external dimensions of a lithium battery, and specifically discloses a first rangefinder and a second rangefinder. The first rangefinder is used to measure the width of the battery, and the second rangefinder is used to measure the length of the battery. Although the utility model also discloses a corresponding technical solution for measuring the battery external dimensions, the battery is not sorted before measurement, which easily leads to errors during measurement.

[0004] Another example is the utility model patent with publication number CN217155331U, which discloses a device for measuring the size of a square lithium battery. Specifically, it discloses a first measuring assembly and a second measuring assembly, both of which are used to measure the dimensions of the battery. However, the patent does not disclose the corresponding technical solutions and technical features for tidying up the battery before measurement.

[0005] It can be seen that in the current market, the battery shape is not pre-processed before being measured. This results in many qualified batteries failing to meet the standards due to lack of processing, which further increases the defective rate of batteries and seriously affects the production efficiency of enterprises.

In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0097] The specific embodiments of the present application are further described below through the examples:

[0098] See also Figure 1-2 A battery dimension measuring device includes: a feeding assembly 100, a discharging assembly 200, a recovery assembly 300, a positioning assembly 400, a first conveying assembly 500, a turntable assembly 600, a first detection assembly 700, a second detection assembly 800, a third detection assembly 900, a shaping mechanism 1000, a second conveying assembly 1100, a detection platform 1200, a fourth detection assembly 1300, a fifth detection assembly 1400, a movable bracket 1500, and a base plate 1700;

[0099] See attached Figure 3 The substrate 1700 is set on the mobile bracket 1500. The mobile bracket 1500 includes a plurality of support legs. The support legs are provided with a fixed platform and universal wheels. The fixed platform is used to fix the mobile bracket 1500, and the universal wheels facilitate the movement of the mobile bracket 1500.

[0100] See attached Figure 9Battery 1600 includes a body 1610, a PCM board 1620, and a connector 1630. Body 1610 includes a battery header 1611 and a battery end 1612. The battery end 1612 is fixedly connected to the battery head 1611. The PCM board 1620 is electrically connected to the battery header 1611. Connector 1630 is electrically connected to the PCM board 1620. A QR code is provided on the surface of battery 1600. The QR code records the standard dimensions of this model of battery 1600, including the standard length and width of body 1610, the standard length and width of battery header 1611, the standard shape of connector 1630, the standard thickness of battery header 1611, and the standard thickness of battery end 1612. The PCM (Protection Circuit Module) is a protection circuit module used to manage the battery module's circuits and is commonly known as a battery protection board.

[0103] Furthermore, the first camera 401 includes a CCD camera. The distance between the first camera 401 and the battery 1600 can be adjusted by adjusting the distance of the first bracket 402 on the first slide rail 403, thereby taking a cleaner photo to facilitate the host computer to make a judgment. After the judgment, the host computer can obtain the spatial position of the battery 1600 in the feeding assembly 100, thereby facilitating the robot to suck it. At the same time, the host computer recognizes the QR code on the battery 1600 to obtain the standard size of the battery model. The standard size is compared with the size obtained later to determine whether the size of the battery 1600 is qualified.

[0104] See attached Figure 6The shaping mechanism 1000 is used to adjust the shape of the battery 1600, and specifically includes a first shaping component and a second shaping component. The first shaping component and the second shaping component are arranged between the third lens 802 and the light source 806. The first shaping component is used to press and shape the battery head 1611 and the battery end 1612 so that the battery head 1611 and the battery end 1612 can remain flat, and prevent wrinkles on the battery head 1611 and the battery end 1612 from causing the measured dimensions of the battery head 1611 and the battery end 1612 to be unqualified. The first shaping component includes a first shaping component and a second shaping component.

When the battery 1600 moves to the processing station, the first cylinder 1002 starts and drives the second connecting plate 1003 When the second connecting plate 1003 moves downward and is in place, the second cylinder 1004 is started, and the second cylinder 1004 drives the third connecting plate 1005 to move horizontally. At the same time, the third connecting plate 1005 drives the first guide rail 1006, the fourth connecting plate 1007, the first movable plate 1008, the push block 1009 and the first spring to move horizontally. When the push block 1009 presses against the battery head 1611, the push block 1009, the first movable plate 1008 and the fourth connecting plate 1007 stop moving. At this time, the second cylinder 1004 continues to apply horizontal pressure, and the first spring is stretched under force to limit the force applied by the fourth connecting plate 1007 to the battery head 1611, so as to prevent the battery head 1611 from being damaged by excessive force. After the shaping is completed, the second cylinder 1004 and the first cylinder 1002 are respectively recovered, and at the same time, each component is driven to be recovered to its original position.

When the battery 1600 moves to the processing station, the third cylinder 1011 starts and pushes the fifth connecting plate 1012, the second guide rail 1013, the fifth fixed plate 1014, the transparent pressure plate 1015 and the second spring to move downward. When the transparent pressure plate 1015 contacts the connector 1630, the fifth fixed plate 1014 stops moving downward. At this time, the third cylinder 1011 continues to move downward, and the second spring is stretched under force to limit the fifth connecting plate 1012 from continuing to move downward, thereby reducing the force exerted by the fifth fixed plate 1014 on the connector 1630, preventing the connector 1630 from being damaged by excessive force. After the shaping is completed, the third cylinder 1011 is retracted upward, and at the same time drives each component to be retracted to its original position.
