Technical Field

[0001] The utility model relates to the technical field of lithium battery size detection, in particular to a device for detecting the size of soft-pack lithium batteries. Background Art

[0002] Since its introduction, lithium-ion batteries have experienced rapid development and widespread use in society due to their superior performance. With advantages unmatched by other batteries, lithium-ion batteries have rapidly been applied to many fields, and their applications in various fields are becoming increasingly widespread. Soft-pack lithium batteries are also a type of lithium battery.

[0003] In this regard, China's patent application number: CN214865357U discloses a soft-pack lithium battery size detection jig, which relates to the field of lithium battery production and manufacturing. It includes a base and a baffle provided with an inclined surface. The inclined surface is provided with a slide groove adapted to the width of the soft-pack lithium battery. The baffle is arranged above the inclined surface and fixed relative to the base. The utility model solves the technical problem of low efficiency in the external dimension detection of lithium batteries in the prior art. When using the soft-pack lithium battery size detection jig of this technical solution, one side of the lithium battery can be parallel to the inclined surface and placed above the slide groove. After releasing the hand, the soft-pack lithium battery will slide down freely along the slide groove under the action of gravity. The lithium battery that slides out is a qualified product; the battery that does not slide out of the slide groove is a defective product. Since this technical solution does not require manual reading, the error is small, and the technical solution completes the operation only by gravity, which has the advantages of saving time and effort and simple operation.

[0004] However, during the detection process, the overall inclined surface cannot be adjusted, so lithium batteries of different weights cannot be detected uniformly. When the lithium batteries are of different sizes, the size values ​​of the lithium batteries cannot be detected, resulting in poor overall detection results and certain limitations in detection. Therefore, it is urgent to improve and perfect the above-mentioned problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a device for detecting the size of soft-pack lithium batteries to solve the problems raised in the above-mentioned background technology, that is, the overall inclined surface cannot be adjusted, so that lithium batteries of different weights cannot be detected uniformly, and when the lithium batteries are of different sizes, the size values ​​of the lithium batteries cannot be detected, resulting in poor overall detection effect and certain limitations in detection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for detecting the size of a soft-pack lithium battery, comprising a base plate, a movable shaft movably mounted on the top surface of the base plate, a detection frame mounted on the back surface of the movable shaft, a rod inserted into the inner side wall of the detection frame, an adjustment plate mounted on the right side surface of the rod, and a detection slot formed inside the detection frame;

[0007] A top plate is installed on the upper surface of the detection frame, a mounting tube is installed on the right side surface of the top plate, a mounting column is provided inside the mounting tube, and a fixing ring is installed on the right side surface of the mounting column.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The device for detecting the size of soft-pack lithium batteries is provided with a bottom plate, a movable shaft, a detection frame, an insertion rod, an adjustment plate, a detection groove, a top plate, a mounting tube, a mounting column, a fixing ring and a telescopic rod. When in use, the lithium battery to be detected is first placed inside the detection groove, and then the telescopic rod is activated to drive the fixing ring to rise through the telescopic rod, and the mounting column is fixedly installed with the fixing ring, and the mounting column is inserted and installed inside the mounting tube, so that the mounting tube will also rise, thereby driving the top plate and the detection frame to adjust the angle, so that soft-pack lithium batteries of different weights can be detected. During the detection, if the soft-pack lithium battery does not slide off the surface of the detection groove, it is an unqualified soft-pack lithium battery. At the same time, by pulling the insertion rod inside the detection frame, the adjustment plate can be moved, so that the size of the detection groove can be adjusted, so that soft-pack lithium batteries of different sizes can be placed for detection, which reflects the practicality of the design.

[0015] 2. The device for detecting the size of a soft-pack lithium battery comprises a measuring ruler, a groove, a resistance block, a resistance pad, an adjusting column, a rotating cylinder, an arc groove, a convex column and a motor body. Before performing the detection, the motor body is first started to drive the rotating cylinder to rotate. When the rotating cylinder rotates, the convex column slides inside the arc groove, so that the adjusting column can rise along with the convex column, and the adjusting column can drive the resistance block and the resistance pad to rise inside the groove. The overall rising effect is good, and the soft-pack lithium battery is limited by the raised resistance block and the resistance pad, and then the size of the soft-pack lithium battery is detected by the scale on the surface of the measuring ruler. When the detection is completed, the motor body rotates in the opposite direction, so that the resistance block and the resistance pad are stored inside the groove, and the size of the detection groove is adjusted to a qualified size. When the soft-pack lithium battery cannot enter the detection groove, the size of the soft-pack lithium battery is unqualified, which reflects the functionality of the design.

Before the detection, the motor body 20 is first started, and the rotating cylinder 17 is driven to rotate by the motor body 20. When the rotating cylinder 17 rotates, the protruding column 19 will slide inside the arc groove 18, so that the adjusting column 16 can follow the protruding column 19 to rise, so that the adjusting column 16 can drive the resistance block 14 and the resistance pad 15 to rise inside the groove 13. The overall rising effect is good. The soft-pack lithium battery is limited by the rising resistance block 14 and the resistance pad 15, and then the size of the soft-pack lithium battery is detected by the scale on the surface of the measuring ruler 12. When the detection is completed, the motor body 20 rotates in the opposite direction, so that the resistance block 14 and the resistance pad 15 are stored in the interior of the groove 13, and the size of the detection groove 6 is adjusted to a qualified size.

The telescopic rod 11 drives the fixed ring 10 to rise, and the mounting column 9 is fixedly installed with the fixed ring 10. The mounting column 9 is inserted and installed inside the mounting cylinder 8, so that the mounting cylinder 8 will also rise, thereby driving the top plate 7 and the detection frame 3 to adjust the angle, so that soft-pack lithium batteries of different weights can be tested. During the test, if it does not slide off the surface of the detection slot 6, it is an unqualified soft-pack lithium battery. At the same time, by pulling the insertion rod 4 inside the detection frame 3, the adjustment plate 5 can be moved, so that the size of the detection slot 6 can be adjusted, so that different sizes of soft-pack lithium batteries can be placed. The soft-pack lithium battery is tested by starting the motor body 20, and the motor body 20 drives the rotating cylinder 17 to rotate, so that when the rotating cylinder 17 rotates, the boss 19 will slide inside the arc groove 18, so that the adjusting column 16 can follow the boss 19 to rise, so that the adjusting column 16 can drive the resistance block 14 and the resistance pad 15 to rise inside the groove 13, and the overall rising effect is good. The soft-pack lithium battery is limited by the rising resistance block 14 and the resistance pad 15, and then the size of the soft-pack lithium battery is detected by the scale on the surface of the measuring ruler 12. When the detection is completed, the motor body 20 rotates in the opposite direction, so that the resistance block 14 and the resistance pad 15 are received inside the groove 13, and the size of the detection groove 6 is adjusted to a qualified size.
