[0002] Lithium-ion batteries, due to their high energy density and excellent cycle performance, are widely used in a variety of applications, including portable electronic devices, electric vehicles, and energy storage devices. The metal casing of lithium-ion batteries is typically coated with a blue film to prevent safety incidents caused by leakage or short circuits. However, this coating process can easily leave bubbles and gaps in the blue film, as well as cause scratches and damage, affecting the safety and quality of the battery. Therefore, a visual inspection system is often used to automatically inspect the coating of lithium batteries to ensure its quality.

[0003] In the prior art, visual inspection mechanisms typically include a camera module and a mounting base for securing the camera module. The camera module can be used to capture images of the lithium battery membrane. The mounting base typically has multiple mounting holes.

[0046] An embodiment of the present application provides a lithium battery membrane visual inspection mechanism. The lithium battery membrane visual inspection mechanism provided in the present application is used to perform visual inspection on the membrane of the lithium battery. The lithium battery membrane visual inspection mechanism of the present application is described in detail below with reference to the accompanying drawings.

[0047] Reference Figures 1 to 8 The lithium battery coating visual inspection mechanism provided in the embodiment of the present application includes: a bracket 10; a camera assembly 11, the camera assembly 11 includes at least two camera modules 110; the at least two camera modules 110 are movably connected to the bracket 10 along a first direction Y, and are spaced apart on the bracket 10 along a second direction X, wherein the first direction Y is the optical axis direction of the camera assembly 11, and the second direction X is perpendicular to the first direction Y; a light source assembly 13, the light source assembly 13 is connected to the bracket 10, and is spaced apart from at least one camera module 110 on the bracket 10, the light source assembly 13 is used to provide light for at least one camera module 110; and a driving mechanism 12, the driving mechanism 12 is connected to the camera assembly 11, and the driving mechanism 12 is used to drive the camera assembly 11 to move along the first direction Y on the bracket 10.

[0048] Specifically, the lithium battery coating visual inspection mechanism includes a bracket 10, a camera assembly 11, a light source assembly 13, and a driving mechanism 12. The bracket 10 is a support frame with good rigidity. The bracket 10 includes a platform plate 101 and a connecting seat 102. The camera assembly 11 is movably connected to the platform plate 101. The platform plate 101 can be fixedly connected to the connecting seat 102 or the platform plate 101 can be movably connected to the connecting seat 102. The first direction Y is the optical axis direction of the camera assembly 11. Movement along the optical axis direction can adjust the focal length of the camera assembly 11, such as Figure 1 and Figure 2 The Y direction is shown in the figure, and this direction is still applicable in subsequent embodiments. The camera assembly 11 includes at least two camera modules 110, wherein multiple camera modules 110 are spaced apart on the bracket 10 and all face the same side of the bracket 10. It can be understood that the lens directions of the multiple camera modules 110 are consistent or similar. In addition, it also includes a light source assembly 13. The light source module 130 is also installed on the bracket 10, spaced apart from at least one camera module 110, and provides light for it.

[0049] The camera module 110 may be a 2D camera or a 3D camera, which is not limited here.

[0050] As a preferred solution, the platform plate 101 can be slidably connected to the connecting seat 102. Specifically, a slider 103 is provided at the bottom of the platform plate 101 along the first direction Y, and a slide rail 104 is provided on the connecting seat 102 along the first direction Y. The slider 103 on the platform plate 101 is driven to slide on the slide rail 104 on the connecting seat 102 by a handwheel screw module. The handwheel screw module includes a main adjusting handwheel 106, a screw rod 107 and a nut. The main adjusting handwheel 106 is fixedly connected to the screw rod 107. The nut is sleeved on the screw rod 107 and is threadedly connected to the screw rod 107. The connecting seat 102 is fixedly connected to the nut. The handwheel screw module drives the platform plate 101 to slide on the slide rail 104 on the connecting seat 102. The principle of the slider 103 on the platform 101 sliding on the slide rail 104 on the connecting seat 102 is as follows: the main adjustment hand wheel 106 rotates to drive the screw 107 to rotate, so that the nut moves along the axial direction of the screw 107. The screw 107 is set along the first direction Y, and the axial direction of the screw 107 is the first direction Y. During the movement of the nut, the connecting seat 102 is driven to move synchronously, so that the platform plate 101 can be moved closer to or away from the lithium battery along the first direction Y, so that the various components on the platform plate 101 can be adjusted as a whole to move closer to or away from the lithium battery along the first direction, and the adjustment is made through the main adjustment hand wheel 106, which is low in cost and simpler and more convenient in adjustment method. In order to limit the progress of the platform plate 101, a locking bolt can be provided at the installation position of the screw 107 on the connecting seat 102. By tightening the locking bolt, the rotation of the screw 107 is limited, thereby limiting the movement of the platform plate 101 along the first direction Y. A ruler can be fixedly connected to the connecting seat 102 along the first direction Y, and the ruler is provided with size marks. By setting the ruler, when adjusting the position of the platform plate 101, the position can be adjusted according to the size marks on the ruler, so that the position of the platform plate 101 in the first direction Y can be adjusted more accurately.

[0051] Specifically, the camera assembly 11 includes at least two camera modules 110. The number of camera modules 110 can be 2, 3, 4, etc. The number can be set according to the actual situation and is not specifically limited in the implementation of this application. At least two camera modules 110 are movably connected to the bracket 10, so that the position of each camera module 110 in the first direction Y can be adjusted individually, so that the method for the lithium battery coating visual inspection mechanism to adjust the position of each camera module 110 is simpler. By arranging multiple camera modules 110 on the bracket 10 at intervals along the second direction X, it is possible to obtain lithium battery coating photos at different positions through multiple camera modules 110, thereby improving the detection accuracy of the lithium battery coating visual inspection mechanism. The second direction X is the moving direction of the lithium battery, such as Figure 1 and Figure 2 The Y direction is shown in the figure, and this direction is still applicable in subsequent embodiments.

[0052] In the embodiment of the present application, by movably connecting the camera module 110 to the bracket 10 and then connecting the driving mechanism 12 to the camera module 110, the position of the camera module 110 along the first direction Y on the bracket 10 can be adjusted through the driving mechanism 12, thereby avoiding the need to disassemble the camera module 110 for position adjustment when the lithium battery is changed to be inspected, making the method of adjusting the position of the camera module 110 by the lithium battery coating visual inspection mechanism simpler, reducing the difficulty of debugging the lithium battery coating visual inspection mechanism when changing the model, and shortening the time for debugging the lithium battery coating visual inspection mechanism when changing the model.

[0053] Optionally, the camera module 110 includes a camera 111 and a mounting base 112; the mounting base 112 includes a first side and a second side arranged in opposition along a third direction Z, and the camera 111 is fixedly connected to the first side; the second side is provided with a slide groove 1120 extending along the first direction Y, and the bracket 10 is installed with a rack 100 along the first direction Y corresponding to the position of the slide groove 1120, wherein the third direction Z is perpendicular to the first direction Y and the second direction X; the driving mechanism 12 is movably connected to the mounting base 112 and cooperates with the rack 100 to drive the mounting base 112 to move along the first direction Y on the rack 100.

[0054] Specifically, the camera module 110 includes a camera 111 and a mounting base 112. The rack 100 can be mounted on the bracket 10 by means of bolts, strong glue, etc., and the present application does not specifically limit the specific mounting method of the rack 100.

[0055] In this embodiment, the driving mechanism 12 cooperates with the rack 100 to realize the movement of the mounting base 112 in the first direction Y. Since the rack 100 is a relatively simple transmission device, the movement of the mounting base 112 in the first direction Y can be realized more simply. The third direction Z is perpendicular to the first direction Y and the second direction X. Figure 1 and Figure 2 The Z direction is shown in the figure, and this direction is still applicable in subsequent embodiments.

[0056] As a preferred solution, a ruler with size marks on it can also be provided on the mounting base 112. By setting the ruler, when adjusting the position of the camera module 110, the position can be adjusted according to the size marks on the ruler, so that the position of the camera module 110 in the first direction Y can be adjusted more accurately.

[0057] In some other embodiments, the mounting base 112 may include a connecting plate and a connecting base, the connecting base having a first side and a second side set away from each other along the third direction Z, a mounting position is provided on the connecting plate, the camera 111 is fixedly installed on the mounting position, a plurality of mounting holes are provided on the connecting plate along the third direction Z, a strip hole is provided on the first side of the connecting base along the third direction Z, a slide groove 1120 is provided on the second side of the connecting base, the strip hole is adapted to the mounting hole, the connecting plate is fixedly connected to the bracket 10 by inserting screws into the strip hole and the mounting hole in sequence, and the position of the connecting plate on the bracket 10 along the third direction Z is adjusted by inserting screws into the mounting holes at different positions, thereby realizing the position adjustment of the camera module 110 along the third direction Z.

[0058] Optionally, the driving mechanism 12 includes a handwheel 120, a rotating shaft 121 and a gear 123; the mounting base 112 includes a side wall 1121 perpendicular to the second direction X, and a accommodating cavity 1122 is provided in the mounting base 112, and a rotating shaft mounting hole 1123 extending along the second direction X and connected to the accommodating cavity 1122 is provided on the side wall 1121; the rotating shaft 121 is passed through the rotating shaft mounting hole 1123; the end of the rotating shaft 121 away from the accommodating cavity 1122 protrudes from the rotating shaft mounting hole 1123 and is fixedly connected to the handwheel 120; the gear 123 is installed on the other end of the rotating shaft 121 that passes through the accommodating cavity 1122, and the gear 123 is engaged with the rack 100. Under the rotation of the handwheel 120, the rotating shaft 121 can drive the mounting base 112 to move along the first direction Y on the rack 100.

[0059] Specifically, the drive mechanism 12 includes a handwheel 120, a rotating shaft 121, and a gear 123. The rotating shaft 121 and the gear 123 can be integrally formed. By rotating the handwheel 120, the rotating shaft 121 drives the gear 123 to engage with the rack 100, thereby achieving movement of the mounting base 112 in the first direction Y. The meshing of the gear 123 and the rack 100 has high transmission precision, small error, and high stability, which can ensure the movement accuracy of the mounting base 112. The handwheel 120 is used for adjustment. The handwheel 120 is a relatively common adjustment component with a simple and low-cost adjustment method. This makes the method of adjusting the position of the camera module 110 in the lithium battery coating visual inspection mechanism simpler and reduces costs.

[0060] Optionally, the mounting base 112 further includes a locking member 1124 , which is movably connected to the mounting base 112 . When the rotating shaft 121 rotates to the target position, the locking member 1124 is used to limit the movement of the mounting base 112 along the first direction Y on the rack 100 .

[0061] Specifically, in the process of adjusting the position of the mounting base 112, the locking member 1124 is used to limit the movement of the mounting base 112 along the first direction Y, so as to accurately fix the mounting base 112 in the position after the movement adjustment, thereby avoiding inaccurate measurement of the lithium battery membrane visual inspection mechanism caused by the movement of the camera module 110 during the inspection process.

[0062] Optionally, a slide column 108 extending along the first direction Y is provided at a position corresponding to the slide groove 1120 on the bracket 10, and the rack 100 is installed on the slide column 108. When the rotating shaft 121 drives the mounting seat 112 to move along the first direction Y on the rack 100, the slide groove 1120 moves along the first direction Y on the slide column 108; the locking member 1124 includes a first end and a second end that are arranged in opposite directions, and the first end is provided with a handle 1125; the second end is threadedly connected to the mounting seat 112 and contacts the slide groove 1120; when the rotating shaft 121 rotates to the target position, the handle 1125 is turned, and the second end drives the slide groove 1120 to abut against the slide column 108 to limit the movement of the slide groove 1120 along the first direction Y on the slide column 108.

[0063] Specifically, refer to Figure 3-4 The slide groove 1120 is a dovetail groove, and the corresponding slide post 108 is a dovetail post. The dovetail groove is a hollow isosceles trapezoid, while the cross-section of the dovetail post is a solid isosceles trapezoid. When the two cooperate with each other, a gap exists between the dovetail groove and the dovetail post. The thickness of the waist of the dovetail groove is relatively thin. By rotating the handle 1125, the locking member 1124 is tightened, driving the waist of the dovetail groove and the waist of the dovetail post to contact each other, thereby restricting the movement of the slide groove 1120, achieving the limit of the mounting seat 112, and thus achieving the position of the camera module 110 on the bracket 10 along the first direction Y. By rotating the handle 1125 and driving the locking member 1124 to tighten, the position of the camera module 110 can be restricted, making the locking method more simple.

[0064] Optionally, there are two camera modules 110, namely a first camera 113 and a second camera 114. The first camera 113 and the second camera 114 are arranged on the bracket 10 at intervals along the second direction X and have the same field of view.

The 2D camera is used to take photos of the side of the lithium battery facing the first camera 113 when it is moving, and the second camera 114 is used to take photos of the outline of the entire lithium battery, so that the lithium battery can be better photographed and inspected. By arranging the light source assembly 13 and the first camera 113 on the bracket 10 along the first direction Y, the light source assembly 13 can provide light for the first camera 113, thereby improving the photo quality of the first camera 113 and improving the inspection quality of the lithium battery packaging visual inspection mechanism.
