Description

Technical Field

[0001] The utility model belongs to the technical field of measurement, and in particular relates to a measuring device structure for a battery cell. Background Art

[0002] With the continuous expansion of the domestic power battery industry, demand for visual inspection of various battery cells and modules is increasing, leading to a surge in non-standard, customized lithium-ion battery equipment. However, the production capacity of high-quality lithium-ion battery equipment is scarce, especially for visual inspection of blue-film cells. Low inspection accuracy and efficiency are leading to significant delivery pressure for companies.

[0003] For this reason, there is a huge demand for battery cell size and defect detection systems for lithium battery equipment. The market urgently needs battery cell and module size and defect detection systems that can be quickly supplied using advanced technology to meet the quality requirements of lithium battery cell appearance inspection in the new energy vehicle market and energy storage equipment.

[0004] The existing measurement methods include using measuring machines or standard imagers to measure dimensions. While this is convenient, the efficiency is low and cannot meet the needs of rapid production testing.

[0005] Therefore, a method has emerged to quickly scan battery cells for measurement by combining a 3D line laser and a 2D line scan camera. However, when assembled, the 3D line laser and the 2D line scan camera are generally installed on the side of the production line through a fixed bracket to directly scan and inspect the battery cells. In order to accurately detect the appearance defects of the battery cells, the distance between the 3D line laser and the 2D line scan camera and the outer surface of the battery cell is a set distance. As a result, the fixedly assembled 3D line laser and 2D line scan camera can only perform appearance defect inspection on a certain type of battery cell, and their compatibility is poor.

[0006] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0007] In response to the above-mentioned technical problems existing in the battery chip measuring device in the prior art, the utility model proposes a new battery chip measuring device, which is adjustable in both the X and Y directions, so that it can measure battery cells of different models and sizes, with good flexibility, compatibility and versatility.

[0008] In order to achieve the above-mentioned utility model / design purpose, this utility model adopts the following technical solutions:

[0009] A battery cell measuring device, comprising:

[0010] the base body;

[0011] and an X-direction moving module, assembled on the base body, movable in the horizontal direction;

[0012] a Y-direction moving module, connected on the X-direction moving module, capable of moving horizontally under the drive of the X-direction moving module, comprising a Y-direction sliding member;

[0013] a measuring assembly, comprising a base, connected on the Y-direction sliding member;

[0014] a first mounting plate set, connected on the base;

[0015] a 3D laser set, assembled on the first mounting plate set, comprising a plurality of 3D line lasers arranged from top to bottom, the plurality of 3D line lasers being adjustable in the horizontal direction position, and at least part of the lasers being adjustable in the height direction position;

[0016] a second mounting plate set, connected on the base;

[0017] a 2D line scanning camera, assembled on the second mounting plate set, the irradiation angle and the position in the Y direction being adjustable;

[0018] a third mounting plate set, connected on the base;

[0019] a bar light source, assembled on the third mounting plate set, the angle and the position in the Y direction being adjustable to adapt to the 2D line scanning camera.

[0020] Compared with the prior art, the battery cell measuring device has the advantages and positive effects that:

[0021] The battery cell measuring device in the embodiment is provided with the base body, the X-direction moving module and the Y-direction moving module are arranged on the base body, and the base of the measuring assembly and the first mounting plate set for assembling the 3D line lasers, the second mounting plate set for assembling the 2D line scanning camera and the third mounting plate set for assembling the bar light source are all connected to the Y-direction sliding member. During measurement, the 3D line lasers and the 2D line scanning camera can be driven to move linearly in the X direction and the Y direction by the X-direction moving module and the Y-direction moving module according to different models and sizes of the battery cells, so that the positions of the 3D line lasers and the 2D line scanning camera in the X direction and the Y direction are adjusted to match different sizes and models of the battery cells for measurement, thereby improving the versatility of the whole measuring device.

[0022] In addition, the plurality of 3D line lasers are arranged to be adjustable in the horizontal direction position, so that the horizontal positions of the 3D line lasers can be adjusted individually when the X-direction moving module is not adjusted to the right position or needs to be finely adjusted.

[0023] When the height of the battery cell needs to be measured, at least one of the height-adjustable 3D line laser can be adjusted in the height direction, so that it can measure the size of the battery cell of different heights.

[0024] The 2D line scanning camera is angle-adjustable and Y-direction position-adjustable. When measuring, the 2D line scanning camera can also be finely adjusted in the Y-direction position to adapt to the measurement position of the battery cell in the Y-direction, and the angle of the irradiation can be adjusted to adapt to different battery cells.

[0025] By setting the X-direction moving module and the Y-direction moving module to make large-range movement, and by cooperating with the 3D line laser and the 2D line scanning camera in the X-direction, the Y-direction, the angle position and the height position, the whole device can adapt to the appearance measurement of more battery cells, has better compatibility and stronger universality.

[0126] Three Y-direction sensing limiting elements are also provided, which have the same structure, arrangement and principle as the X-direction moving module 200, and are used for limiting the position of the Y-direction moving module 300 along the Y direction.

[0127] In some embodiments of the present application, the X-direction screw 280 nut assembly of the X-direction moving module 200 comprises the X-direction screw 280, the connecting shaft 600, and the connecting end connected to the X-direction screw 280.

[0128] The encoder comprises:

[0129] The encoder body 710 is assembled to the encoder mounting seat 720, and the encoder mounting seat 720 is assembled to the X-direction base plate 130.

[0130] The rotating shaft 730 is connected to the connecting shaft 600 through the second coupling 800.

[0131] When the X-direction servo motor 210 drives the X-direction screw 280 nut to move left and right through the first coupling, the rotation of the X-direction screw 280 drives the connecting shaft 600 to rotate, and at the same time, the rotating shaft 730 on the rotary encoder is also rotated. The real-time rotating position information of the encoder is fed back to the PLC controller of the entire measuring device. The PLC controller can obtain the distance of the X-direction moving module 200 moving in the X direction according to the information fed back by the encoder. When the PLC controller obtains that the horizontal moving position reaches the measured battery position, the 3D line laser 510 and the 2D line scanning camera 520 are instructed to be turned on, and the scanning detection of the blue film battery appearance is completed through the 3D line laser 510 and the 2D line scanning camera 520.

[0132] The servo PLC controller and the encoder are used to realize the real-time detection and acquisition of the moving position of the X-direction moving module 200, and can real-time feedback the position information of the 3D line laser 510 and the 2D line scanning camera 520 and trigger the 3D line laser 510 and the 2D line scanning camera 520 to complete the scanning, so that high-precision positioning, informatization and intelligent high-level measurement are realized.

Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some technical features. The modification or replacement does not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed by the present application.
