[0047] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0050] In the description of this embodiment, the terms "upper", "lower", "left", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplified operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0051] See also Figures 1 to 4 In this embodiment, a tab detection system is proposed, which includes a detection device and a lithium battery transfer device. The detection device is arranged at an operation position (i.e., a detection position), and the detection device is configured to detect the tab 100 of the lithium battery 100. Under the action of the lithium battery transfer device, the lithium battery 100 at the loading position can be transported to the operation position, and under the action of the detection device, the tab 100 of the lithium battery 100 can be detected, and then under the action of the lithium battery transfer device, the lithium battery 100 that has been detected is transferred to the unloading position.

[0052] In this embodiment, the detection device includes a detection bracket 1, a detection mechanism and a plurality of cameras 2. The detection bracket 1 is arranged at the working position and can be used to carry the lithium battery 100 to be detected, that is, to carry the lithium battery 100 transported from the loading position to the working position by the lithium battery transfer device. The detection mechanism and the plurality of cameras 2 are electrically connected, and the plurality of cameras 2 are respectively arranged relative to the positions to be detected on the lithium battery 100. In order to improve the accuracy of the camera 2 taking pictures, each camera 2 is correspondingly provided with a light source 3.

[0053] It is understandable that when one of the lithium batteries 100 (hereinafter referred to as material a) is inspected, the inspected lithium battery 100 is removed from the inspection bracket 1 by the lithium battery material moving device, and material a is driven to move to the unloading position. While the lithium battery material moving device is moving, another lithium battery 100 (hereinafter referred to as material b) can be moved from the loading bracket 5 to the inspection bracket 1, and material b is inspected under the action of the camera 2 and the inspection mechanism. Compared with manual inspection of the tab 110, the inspection of the tab 110 by the tab inspection system in the utility model can improve the inspection efficiency of the entire inspection line.

[0054] In this embodiment, the detection bracket 1 includes two detection frames arranged at intervals along the third direction, and the lithium battery 100 can be mounted on the two detection frames, and the length direction of the lithium battery 100 is consistent with the third direction. The lithium battery material transfer device can be arranged between the two detection frames along the second direction to transport the lithium battery 100, and the second direction is arranged perpendicular to the third direction. The first direction, the second direction and the third direction are as follows Figure 1 The coordinate system shown in .

[0055] It should be noted that the above-mentioned industrial visual inspection equipment and related inspection methods based on the camera 2 and the detection mechanism used in conjunction with it to obtain the target product image and then identify and detect the features on the target product image can adopt the existing technology. It is not the part of the present application that improves the existing technology, so it will not be elaborated.

[0056] Please combine Figure 1 and Figure 4 For reference, the tab detection system further includes a plurality of moving mechanisms 8, which are respectively arranged in one-to-one correspondence with the cameras 2, and the moving mechanisms 8 are configured to adjust the position of the camera 2 to keep the camera 2 arranged relative to the position to be detected on any lithium battery 100, that is, arranged relative to the tab 110. It can be understood that by adjusting the position of the camera 2, so that the plurality of cameras 2 can detect lithium batteries 100 of different models, the applicability of the tab detection system is improved.

[0057] Specifically, the moving mechanism 8 includes a fixed portion 81, a first moving portion 82, a second moving portion 83 and a third moving portion 84. The first moving portion 82 can be slidably arranged on the fixed portion 81 along the X direction; the second moving portion 83 can be slidably arranged on the first moving portion 82 along the Y direction; the third moving portion 84 can be slidably arranged on the second moving portion 83 along the Z direction; the X direction, the Y direction and the Z direction are arranged perpendicular to each other. It can be understood that the X direction here can be consistent with the first direction, the second direction or the third direction, the Y direction can also be consistent with the first direction, the second direction or the third direction, and the Z direction can also be consistent with the first direction, the second direction or the third direction. Among them, the X direction, the Y direction and the Z direction are as follows Figure 4 The coordinate system is shown in .

[0058] Exemplarily, in this embodiment, a gantry 12 is also provided, and the gantry 12 is arranged above the detection bracket 1. Two groups of moving mechanisms 8 and cameras 2 are arranged on the gantry 12. Under the action of the moving mechanisms 8, the two cameras 2 can be respectively arranged corresponding to the tops of the tabs 110 on both sides of the lithium battery 100. Two groups of moving mechanisms 8 and cameras 2 are also respectively arranged on both sides of the detection bracket 1 along the third direction. Under the action of the moving mechanisms 8, the two cameras 2 can be respectively arranged corresponding to the sides of the tabs 110 on both sides of the lithium battery 100 along the third direction. In addition, two groups of moving mechanisms 8 and cameras 2 are also respectively arranged on both sides of the detection bracket 1 along the second direction. Under the action of the moving mechanisms 8, the two cameras 2 can be respectively arranged corresponding to the sides of the tabs 110 on both sides of the lithium battery 100 along the second direction.

[0059] It should be noted that the movement between the fixed part 81 and the first movable part 82, between the first movable part 82 and the second movable part 83, and between the second movable part 83 and the third movable part 84 can be controlled by existing linear drive mechanisms such as cylinders, electric cylinders, and screws, and no specific restrictions are made in this embodiment.

[0060] Based on the above, this embodiment also proposes a lithium battery material transfer device. Figure 1 and Figure 2 For reference, the lithium battery material moving device is provided with a loading bracket 5, a loading buffer bracket 6, a material moving mechanism 4 and a material replenishing mechanism 7 at the loading position. The loading bracket 5 and the loading buffer bracket 6 can both receive and carry the lithium battery 100 delivered by the external loading device; the material moving mechanism 4 can move the lithium battery 100 on the loading bracket 5 to the working position, and at the same time can move the lithium battery 100 that has been inspected and is at the working position to the unloading position; the material replenishing mechanism 7 is configured to move the lithium battery 100 on the loading buffer bracket 6 to the loading bracket 5.

[0061] It is understandable that the material moving mechanism 4 can move the lithium battery 100 that has been tested at the working position to the unloading position during the moving process, and the material moving mechanism 4 can drive the lithium battery 100 on the loading bracket 5 to move to the working position for testing while moving, thereby improving the transportation efficiency of the lithium battery 100 between the loading position, the working position and the unloading position. And when the lithium battery 100 on the loading bracket 5 is removed, the lithium battery 100 on the loading buffer bracket 6 can be moved to the loading bracket 5 under the action of the feeding mechanism 7, and then the material moving mechanism 4 repeats the above-mentioned material moving process, thereby further improving the transportation efficiency of the lithium battery 100 between the loading position, the working position and the unloading position.

[0062] The material shifting mechanism 4 comprises a material shifting bracket 41, a material shifting movable part 43, a first material shifting bearing part 42 and a second bearing part. The first material shifting bearing part 42 and the second bearing part are both arranged on the material shifting bracket 41, and the first material shifting bearing part 42 and the second material shifting bearing part are both configured to bear the lithium battery 100; the material shifting movable part 43 can synchronously drive the first material shifting bearing part 42 and the second material shifting bearing part, and the material shifting movable part 43 has a first working position and a second working position. When the material shifting movable part 43 is in the first working position, the first material shifting bearing part 42 is docked with the loading position, and the second material shifting bearing part is docked with the working position. When the material shifting movable part 43 is in the second working position, the first material shifting bearing part 42 is docked with the working position, and the second material shifting bearing part is docked with the unloading position. The material shifting movable part 43 is configured to drive the material shifting bracket 41 to travel back and forth between the first working position and the second working position.

[0063] In this embodiment, the material moving part 43 includes a material lateral moving module 431 and a material upward moving module 432. The material lateral moving module 431 is arranged along the second direction, the material upward moving module 432 is arranged along the first direction, the material upward moving module 432 is arranged at the moving end of the material lateral moving module 431, and the material moving bracket 41 is arranged at the moving end of the material upward moving module 432. Under the action of the material lateral moving module 431 and the material upward moving module 432, the material moving bracket 41 can be driven to change its position in the second direction and the first direction, so as to be suitable for different upper positions and material unloading positions, thereby further improving the applicability of the tab detection system.

[0064] It can be understood that the material transverse shifting module can drive the material moving upward shifting module 432 to move along the second direction, and the material moving upward shifting module 432 can drive the material moving bracket 41 to move along the first direction. Under the joint action of the material transverse shifting module 431 and the material moving upward shifting module 432, the first material moving bearing part 42 can be driven to be in a position relative to the lithium battery 100, which is convenient for material picking and unloading.

[0065] In addition, the material shifting transverse movement module 431 and the material shifting upward movement module 432 can select linear movement modules in the prior art, such as a cylinder, an electric cylinder, a screw, etc., and no specific limitation is made in this embodiment.

[0066] Specifically, the first material moving bearing part 42 and the second material bearing part are arranged linearly along the second direction. Before the lithium battery 100 is tested, when the external loading device places material a and material b on the loading bracket 5 and the loading buffer bracket 6 respectively, under the action of the material moving mechanism 4, material a is placed on the first material moving bearing part 42, and under the action of the material moving part 43, material a is moved to the detection bracket 1, and then the first material moving bearing part 42 returns to the loading bracket 5 again, and the second material moving bearing part grabs material a. At the same time, under the action of the feeding mechanism 7, material b can be moved from the loading buffer bracket 6 to the loading bracket 5, and the first material moving bearing part 42 grabs material b. After the detection of material a is completed, under the action of the material moving part 43, material a can be driven to move to the unloading position, and material b can be moved to the detection position, that is, material b is moved to the detection bracket 1 at the same time, and then material b is detected by the detection mechanism.

[0067] Further, the first material shifting bearing part 42 includes a material shifting bearing platform 421, a material shifting double-headed cylinder 422 and two material shifting clamps 433, the material shifting bearing platform 421 is arranged on the material shifting bracket 41, the lithium battery 100 is arranged on the material shifting bearing platform 421, and the material shifting bearing platform 421 can move along the first direction; the material shifting double-headed cylinder 422 is arranged on the material shifting bearing platform 421, and the two material shifting clamps 433 are respectively arranged at the two output ends of the material shifting double-headed cylinder 422, and the two material shifting clamps 433 can move along the first direction. The first direction, the second direction and the third direction are arranged perpendicular to each other. It can be understood that the structures of the first material shifting bearing part 42 and the second bearing part are the same, which will not be repeated here.

[0068] It should be noted that the material-transferring double-headed cylinder 422 and its use are both existing technologies. Of course, the material-transferring double-headed cylinder 422 can also be selected to have a driving element with a two-way output end, and no specific limitation is made in this implementation.

[0069] In this embodiment, when clamping the lithium battery 100, the two output ends of the material moving double-headed cylinder 422 move along the second direction, so that the distance between the two material moving clamps 433 is greater than the width of the lithium battery 100, and the material moving support platform 421 moves along the first direction, so that the material moving support platform 421 contacts the lithium battery 100, and then the two output ends of the material moving double-headed cylinder 422 approach each other, and the two material moving clamps 433 move along the first direction until the bottom of the two material moving clamps 433 abut against the top of the lithium battery 100, at which time the clamping of the lithium battery 100 is completed.

[0070] Exemplarily, a cylinder is correspondingly arranged between the two output ends of the double-headed material moving cylinder 422 and the two material moving clamps 433. The cylinder is arranged at the output end of the double-headed cylinder. Under the action of the double-headed cylinder, the movement of the cylinder can be controlled, and then the movement of the clamp can be controlled. When the clamp moves to a suitable position, the height of the clamp is controlled by the cylinder to facilitate the clamping of the lithium battery 100.

[0071] In addition, the material transfer clamp 433 is preferably a plate-like structure, which is not only convenient for fixing on the output end of the cylinder, but also can avoid damage to the surface of the lithium battery 100 due to uneven pressure between the two material transfer clamps 433 and the material transfer support platform 421.

[0072] Please combine Figure 1 and Figure 3 For reference, the detection bracket 1, the loading bracket 5 and the loading buffer bracket 6 are linearly spaced along the second direction; the feeding mechanism 7 is configured to move the lithium battery 100 on the loading buffer bracket 6 to the loading bracket 5. The loading bracket 5 includes two loading brackets spaced along the third direction, and the loading buffer bracket 6 includes two loading buffer brackets spaced along the third direction. The feeding mechanism 7 can move between the two loading buffer brackets and the two loading brackets to move the lithium battery 100 on the loading buffer bracket 6 to the loading bracket 5.

[0073] In this embodiment, the feeding mechanism 7 includes a feeding bracket 71 and a feeding bearing portion 72. The feeding bracket 71 can move back and forth between the feeding bracket 5 and the feeding buffer bracket 6; the feeding bearing portion 72 is arranged on the feeding bracket 71, and the feeding bearing portion 72 is configured to grab or place the lithium battery 100. It can be understood that after the lithium battery 100 on the feeding bracket 5 is transported to the detection bracket 1, the feeding bearing portion 72 grabs the lithium battery 100 on the feeding buffer bracket 6. After the grabbing is completed, under the action of the feeding bracket 71, the grabbed lithium battery 100 can be transported to the feeding bracket 5.

[0074] In addition, the feeding support 71 can be controlled to move along the second direction by an existing linear drive mechanism such as a pneumatic cylinder, an electric cylinder, a screw, etc., and no specific limitation is made in this embodiment.

[0075] Furthermore, the feeding support part 72 includes a feeding support platform 721, a feeding double-headed cylinder 722 and two feeding clamps 723. The feeding support platform 721 is arranged on the feeding bracket 71, and the feeding support platform 721 can move along the first direction; the feeding double-headed cylinder 722 is arranged on the feeding support platform 721, and the two feeding clamps 723 are respectively arranged at the two output ends of the feeding double-headed cylinder 722, and the two feeding clamps 723 can move along the first direction. When moving the lithium battery 100 from the loading buffer bracket 6 to the loading bracket 5, first move the feeding bracket 71 to the corresponding position of the corresponding loading buffer bracket 6, and when clamping the lithium battery 100, the two output ends of the feeding double-headed cylinder 722 move along the second direction, so that the distance between the two feeding clamps 723 is greater than the width of the lithium battery 100, and the feeding support platform 721 moves along the first direction to make the feeding support platform 721 contact with the lithium battery 100, and then the two output ends of the feeding double-headed cylinder 722 approach each other, and the two feeding clamps 723 move along the first direction until the bottom of the two feeding clamps 723 abut against the top of the lithium battery 100, at this time, the clamping of the lithium battery 100 is completed, and then the feeding bracket 71 moves along the second direction to place the lithium battery 100 on the loading bracket 5.

[0076] In addition, the feeding support platform 721 can be controlled to move along the second direction by an existing linear drive mechanism such as a pneumatic cylinder, an electric cylinder, a screw, etc., and no specific limitation is made in this embodiment.

[0077] The material replenishment clamp 723 is preferably a plate-like structure, which is not only convenient for fixing on the output end of the cylinder, but also can avoid damage to the surface of the lithium battery 100 due to uneven pressure between the two material replenishment clamps 723 and the material replenishment support platform 721.

[0078] The lithium battery material transfer device also includes a material transfer bracket 9, a material transfer buffer bracket 10 and a material transfer mechanism 11 at the material transfer position. The material transfer bracket 9 is used to receive the lithium battery 100 transported by the material transfer mechanism 4: the material transfer buffer bracket 10 can buffer the lithium battery 100 that has passed the inspection; the material transfer mechanism 11 can move the lithium battery 100 with a qualified inspection result on the material transfer bracket 9 to the material transfer buffer bracket 10. The lithium battery material transfer device also includes a material transfer manipulator (not shown in the figure), which is electrically connected to the inspection mechanism, and the material transfer manipulator is configured to take away the lithium battery 100 on the material transfer bracket 9.

[0079] It can be understood that when the inspected lithium battery 100 is transferred to the unloading bracket 9, the inspection mechanism can feedback a signal to the unloading robot, and the unloading robot grabs the unqualified lithium battery 100 to the defective bin (not shown in the figure), and when the qualified lithium battery 100 is on the unloading bracket 9, the unloading mechanism 11 moves the qualified lithium battery 100 to the unloading buffer bracket 10, and then moves the lithium battery 100 to the qualified bin (not shown in the figure) through an external robot (not shown in the figure).

[0080] In addition, after the lithium batteries 100 on the detection bracket 1 are conveyed to the unloading bracket 9, the unqualified lithium batteries 100 are grabbed by the above-mentioned unloading robot and taken to the defective bin, and the qualified lithium batteries 100 are grabbed by the unloading mechanism 11. After the grabbing is completed, the unloading mechanism 11 moves along the second direction. Under the action of the unloading mechanism 11, the grabbed lithium batteries 100 can be conveyed to the unloading cache bracket 10, and then the lithium batteries 100 are moved to the qualified bin by an external robot (not shown in the figure).

[0081] In addition, the unloading mechanism 11 can be controlled to move along the second direction by an existing linear drive mechanism such as a pneumatic cylinder, an electric cylinder, a screw, etc., and no specific limitation is made in this embodiment.

[0082] Specifically, the unloading mechanism 11 includes an unloading support platform, a double-headed unloading cylinder and two unloading clamps. The unloading support platform can move along a first direction; the double-headed unloading cylinder is arranged on the unloading support platform, and the two unloading clamps are respectively arranged at two output ends of the double-headed unloading cylinder, and the two unloading clamps can move along the first direction. When the lithium battery 100 needs to be moved from the unloading bracket 9 to the unloading buffer bracket 10, the unloading support platform is first moved to the position corresponding to the unloading bracket 9. When clamping the lithium battery 100, the two output ends of the unloading double-headed cylinder are controlled to move along the second direction, so that the distance between the two unloading clamps is greater than the width of the lithium battery 100. The unloading support platform moves along the first direction to make the unloading support platform contact the lithium battery 100. Then the two output ends of the unloading double-headed cylinder are close to each other, and the two unloading clamps move along the first direction until the bottom of the two unloading clamps abut against the top of the lithium battery 100. At this time, the clamping of the lithium battery 100 is completed. Then the unloading support platform moves along the second direction to place the lithium battery 100 on the unloading buffer bracket 10 to complete the handling of qualified products.

[0083] In addition, the unloading support platform can be controlled to move along the first direction by an existing linear drive mechanism such as a pneumatic cylinder, an electric cylinder, a screw, etc., and no specific limitation is made in this embodiment.

[0084] The blanking clamp is preferably a plate-like structure, which is not only convenient for fixing on the output end of the cylinder, but also can avoid damage to the surface of the lithium battery 100 due to uneven pressure between the two blanking clamps and the blanking support platform.

[0085] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
