DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0051] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0052] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0053] See also Figures 1-9 As shown, the six-side inspection device for the appearance of a battery cell provided in the present application includes a frame 100 , a feeding mechanism 130 , a side inspection mechanism 110 , a rotating mechanism 140 , a top surface inspection mechanism 150 and a bottom surface inspection mechanism 160 .

[0054] The feeding mechanism 130 is provided on the frame 100 and is used to transport the battery cells 170 . By transporting the battery cells 170 to the position to be inspected, the battery cells 170 can be photographed and inspected in cooperation with the side inspection mechanism 110 .

[0055] See also Figure 2 As shown, the side detection mechanism 110 includes a first drive assembly, a first camera assembly, and a second camera assembly. The first drive assembly is mounted on the frame 100, and the first camera assembly and the second camera assembly are respectively connected to the first drive assembly. The first drive assembly is used to drive at least one of the first camera assembly and the second camera assembly to move to adjust the distance between the first camera assembly and the second camera assembly. The first camera assembly and the second camera assembly are respectively used to photograph and inspect the opposite sides of the battery cell 170 from opposite sides of the battery cell 170 on the feeding mechanism 130. When photographing and inspecting the side of the battery cell 170, the feeding mechanism 130 transports the battery cell 170 to the bottom of the side detection mechanism 110. The first drive assembly then adjusts the distance between the first camera assembly and the second camera assembly, thereby adjusting the focal length of the first camera assembly and the second camera assembly to facilitate photographing and inspecting the opposite sides of the battery cell 170.

[0056] The rotating mechanism 140 is connected to one of the feeding mechanism 130 and the side detection mechanism 110, and is used to drive one of the feeding mechanism 130 and the side detection mechanism 110 to rotate relative to the other, so that the side detection mechanism 110 is directly opposite two different opposite side surfaces of the battery cell 170 on the feeding mechanism 130. Through the configuration of the rotating mechanism 140, after the first and second camera assemblies complete the imaging and inspection of a set of opposite side surfaces of the battery cell 170, the rotating mechanism 140 rotates one of the side detection mechanism 110 and the feeding mechanism 130, so that the first and second camera assemblies are directly opposite the next set of opposite side surfaces of the battery cell 170 and also perform imaging and inspection. The configuration of the rotating mechanism 140 improves the efficiency of the battery cell six-side appearance inspection equipment in inspecting the battery cells 170. Since the detection equipment in the related art needs to set up a group of shooting components for each side of the battery cell 170 to perform shooting and detection, the battery cell appearance six-side detection equipment in the present application reduces two groups of shooting components through the setting of the rotating mechanism 140, thereby reducing the cost of the battery cell appearance six-side detection equipment.

[0057] The top surface detection mechanism 150 is installed on the frame 100 and is used to photograph and inspect the top surface 171 of the battery cell 170 on the feeding mechanism 130. After the side detection mechanism 110 photographs and inspects the battery cell 170, the feeding mechanism 140 transports the battery cell 170 to the bottom of the top surface detection mechanism 150 and photographs and inspects the top surface 171 of the battery cell 170.

[0058] The bottom surface detection mechanism 160 is disposed on the frame 100 and is used to photograph and detect the bottom surface 172 of the battery cell 170 .

[0059] As an embodiment, the first drive assembly includes a first power component, a first transmission component, a second power component and a second transmission component.

[0060] The first power component is mounted on the frame 100. The first transmission component is in driving connection between the first power component and the first camera assembly, and is used to drive the first camera assembly toward or away from the second camera assembly under the drive of the first power component. The first power component drives the first transmission component to move the first camera assembly, thereby adjusting the distance between the first and second camera assemblies. This allows the rotation mechanism 140 to drive the battery cells 170 on the feeding mechanism 130 to rotate, and the distance between the first and second camera assemblies can be adjusted to allow for imaging and inspection of opposite sides of the battery cells 170 of varying thicknesses.

[0061] A second power component is mounted on the frame 100. A second transmission component is drivingly connected between the second power component and the second camera assembly, thereby driving the second camera assembly toward or away from the first camera assembly. The second power component drives the second transmission component to move the second camera assembly, thereby adjusting the spacing between the first and second camera assemblies. This allows the battery cells 170 on the feed mechanism 130 to rotate after the rotation mechanism 140 drives the first and second camera assemblies to rotate, thereby allowing for imaging and inspection of opposing sides of the battery cells 170 of varying thicknesses.

[0062] In the above scheme, the first and second camera assemblies are driven by different power components to adjust the distance between them. That is, the first and second camera assemblies do not share a power component when adjusting the distance. Of course, in specific applications, as an alternative embodiment, the first and second camera assemblies can also share the same power component when adjusting the distance. Specifically, in this alternative embodiment, the first drive assembly includes a first transmission component, a second transmission component, and a fourth power component. The fourth power component is disposed on the frame 100. The first transmission component is transmission-connected between the fourth power component and the first camera assembly to drive the first camera assembly toward or away from the second camera assembly under the drive of the fourth power component. The second transmission component is transmission-connected between the fourth power component and the second camera assembly to drive the second camera assembly toward or away from the first camera assembly under the drive of the fourth power component, thereby adjusting the distance between the first and second camera assemblies. By having the fourth power component simultaneously power the first and second transmission components, the cost of the battery cell six-side appearance inspection equipment is reduced.

[0063] See also Figure 2 As shown, as an embodiment, the first transmission component includes a first screw rod 111 and a first sliding seat 112. The first sliding seat 112 is slidably connected to the first screw rod 111, and the first shooting assembly is connected to the first sliding seat 112. The setting of the first screw rod 111 and the first sliding seat 112 provides the first shooting assembly with movement support in the second horizontal direction.

[0064] The first power component includes a first motor 113, the output end of the first motor 113 is transmission-connected to the first screw rod 111, and the first motor 113 is used to drive the first screw rod 111 to rotate so that the first sliding seat 112 drives the first shooting assembly to move along the first screw rod 111 toward or away from the second shooting assembly. The first motor 113 provides rotational force to the first screw rod 111, so that the first sliding seat 112 can drive the first shooting assembly to slide on the first screw rod 111.

[0065] The second transmission component includes a second screw rod 116 and a second sliding seat 117. The second sliding seat 117 is slidably connected to the second screw rod 116. The second shooting assembly is connected to the second sliding seat 117. The arrangement of the second screw rod 116 and the second sliding seat 117 provides the second shooting assembly with movement support in the second horizontal direction.

[0066] The second power component includes a second motor 118, the output end of the second motor 118 is transmission-linked to the second screw rod 116, and the second motor 118 is used to drive the second screw rod 116 to rotate so that the second sliding seat 117 drives the second shooting assembly to move along the second screw rod 116 toward or away from the first shooting assembly. The second motor 118 provides rotational force to the second screw rod 116, so that the second sliding seat 117 can drive the second shooting assembly to slide on the second screw rod 116.

[0067] In one embodiment, the first imaging component includes a first 2D camera 114 and a first 3D camera 115. The first 2D camera 114 is used to capture a two-dimensional image of the side surface of the battery cell 170 on the feeding mechanism 130, while the first 3D camera 115 is used to capture a three-dimensional image of the side surface of the battery cell 170 on the feeding mechanism 130. The six-side inspection apparatus for the battery cell appearance also includes a control computer. The first 2D camera 114 and the first 3D camera 115 transmit the captured two-dimensional and three-dimensional images, respectively, to the control computer. The control computer analyzes the two-dimensional and three-dimensional images to determine whether there is damage on the side surface and curved surface of the battery cell 170 and calculate the location and depth of the damage.

[0068] In one embodiment, the second imaging assembly includes a second 2D camera 119 and a second 3D camera 120. The second 2D camera 119 is used to capture a two-dimensional image of the side of the battery cell 170 on the feeding mechanism 130, while the second 3D camera 120 is used to capture a three-dimensional image of the side of the battery cell 170 on the feeding mechanism 130. The second 2D camera 119 and the second 3D camera 120 capture the battery cell 170 directly opposite the first 2D camera 114 and the first 3D camera 115, and transmit the resulting two-dimensional and three-dimensional images to a control computer. The control computer analyzes the two-dimensional and three-dimensional images to determine whether there is damage on the side and curved surface of the battery cell 170 and calculate the location and depth of the damage.

[0069] See also Figure 1 、 Figure 4 、 Figure 5As shown, as an embodiment, the six-sided inspection apparatus for the appearance of a battery cell includes at least two feeding mechanisms 130, each of which is used to transport battery cells 170 along a first horizontal direction, and at least two feeding mechanisms 130 are arranged side by side along a second horizontal direction, which is perpendicular to the first horizontal direction. By arranging two groups of feeding mechanisms 130 side by side in the second horizontal direction, when the side inspection mechanism 110 is photographing and inspecting the battery cells 170 on one of the feeding mechanisms 130, the other feeding mechanism 130 is simultaneously loading the battery cells 170, so that the next group of battery cells 170 can be quickly photographed and inspected, thereby improving the overall inspection efficiency of the six-sided inspection apparatus for the appearance of a battery cell.

[0070] As an embodiment, the six-sided inspection device for the appearance of battery cells includes two feeding mechanisms 130 distributed side by side in the second horizontal direction, and can also be replaced by three, four or more feeding mechanisms 130. By setting up two feeding mechanisms 130, when the side inspection mechanism 110 is photographing and inspecting the battery cells 170 on one of the feeding mechanisms 130, the other feeding mechanism 130 is simultaneously performing loading work, so as to quickly carry out photographing and inspection of the next group of battery cells 170, thereby improving the overall inspection efficiency of the six-sided inspection device for the appearance of battery cells.

[0071] The six-sided inspection equipment for the appearance of a battery cell also includes a first horizontal moving assembly 101 and a first lifting assembly 102. The output end of the first lifting assembly 102 is connected to the side inspection mechanism 110 to drive the side inspection mechanism 110 to move up and down. The first horizontal moving assembly 101 is connected to the frame 100, and the output end of the first horizontal moving assembly 101 is connected to the first lifting assembly 102 to drive the first lifting assembly 102 to drive the side inspection mechanism 110 to move along a second horizontal direction, so that the side inspection mechanism 110 is moved above at least two feeding mechanisms 130. Through the arrangement of the first horizontal moving assembly 101 and the first lifting assembly 102, the side inspection mechanism 110 can move up and down and in the second horizontal direction, so that the side inspection mechanism 110 can quickly move close to the battery cell 170 on the feeding mechanism 130.

[0072] As an embodiment, the feeding mechanism 130 includes one or more supporting platforms 133 , a first clamping assembly 131 and a second horizontal moving assembly 132 .

[0073] The carrying platform 133 is used to carry the battery cells 170. The first clamping assembly 131 is connected to the carrying platform 133 and is used to clamp the battery cells 170 on the carrying platform 133 from opposite sides of the carrying platform 133. The second horizontal movement assembly 132 is connected to the frame 100, and the output end of the second horizontal movement assembly 132 is connected to the carrying platform 133 to drive the carrying platform 133 to drive the first clamping assembly 131 to move horizontally along a first horizontal direction. When the battery cells 170 are placed on the carrying platform 133, the first clamping assembly 131 clamps the battery cells 170 on the carrying platform 133 on both sides of the carrying platform 133. After the battery cells 170 on the carrying platform 133 are clamped, the second horizontal movement assembly 132 drives the carrying platform 133 to move below the side detection mechanism 110, so that the side detection mechanism 110 can photograph and detect the battery cells 170 on the carrying platform 133.

[0074] As an embodiment, the feeding mechanism 130 further includes a negative pressure drive assembly 134. The carrying platform 133 is provided with adsorption holes 135. The negative pressure drive assembly 134 is connected to the adsorption holes 135 to provide negative pressure for the adsorption holes 135 to adsorb the battery cell 170 onto the carrying platform 133. When the carrying platform 133 moves with the battery cell 170 to the bottom of the side detection mechanism 110, the first clamping jaw assembly 131 releases the battery cell 170, and the battery cell 170 is adsorbed on the carrying platform 133 by the negative pressure. At this time, the side detection mechanism 110 photographs and detects the side of the battery cell 170. The battery cell 170 is adsorbed on the carrying platform 133 through the negative pressure drive assembly 134 and the adsorption holes 135, so that the battery cell 170 is not blocked on the side when being photographed by the side detection mechanism 110, thereby improving the accuracy and efficiency of the photographing and detection.

[0075] As an embodiment, the rotating mechanism 140 includes a gear 141 , a rack 142 and a third power component 143 .

[0076] Gear 141 is connected to one end of the support platform 133 to drive the support platform 133 and the first clamping assembly 131 to rotate. Rack 142 is meshed with gear 141. A third power component 143 is provided on the second horizontal movement assembly 132, and its output end is transmission-connected to rack 142 to drive rack 142, thereby driving gear 141 and the support platform 133 to rotate horizontally. After the side detection mechanism 110 completes photographing and inspecting two opposing side surfaces of the battery cell 170, the third power component 143 drives rack 142 to move. Since rack 142 is meshed with gear 141, the movement of rack 142 drives gear 141 to rotate, thereby rotating the support platform 133. At this point, the battery cell 170 is attracted to the support platform 133 by negative pressure. The rotation of the support platform 133 drives the battery cell 170 to rotate synchronously, positioning the next two opposing side surfaces of the battery cell 170 directly opposite the first and second imaging assemblies, respectively, for photographic inspection.

[0077] As an implementation, see Figure 3 As shown, the top surface inspection mechanism 150 includes a third camera assembly 153, a second lifting assembly 152, and a third horizontal movement assembly 151. The third camera assembly 153 is used to photograph and inspect the top surface 171 of the battery cell 170 on the feeding mechanism 130. The output end of the second lifting assembly 152 is connected to the third camera assembly 153 to drive the third camera assembly 153 to move up and down. The third horizontal movement assembly 151 is connected to the frame 100. The output end of the third horizontal movement assembly 151 is connected to the second lifting assembly 152 to drive the second lifting assembly 152 to move the third camera assembly 153 in a second horizontal direction. When the second horizontal movement assembly 132 drives the carrying platform 133 to move below the top surface inspection mechanism 150, the third horizontal movement assembly 151 and the second lifting assembly 152 drive the third camera assembly 153 to approach the battery cell 170 on the carrying platform 133 and face the top surface 171 of the battery cell 170, so as to facilitate photographing and inspecting the top surface 171 of the battery cell 170.

[0078] The third camera assembly 153 includes a third 2D camera and a third 3D camera. The third 2D camera is used to capture a two-dimensional image of the top surface 171 of the battery cells 170 on the feeding mechanism 130, while the third 3D camera is used to capture a three-dimensional image of the top surface 171 of the battery cells 170 on the feeding mechanism 130. The third 2D camera and the third 3D camera transmit the resulting two-dimensional and three-dimensional images, respectively, to a control computer. The control computer analyzes the two-dimensional and three-dimensional images to determine whether the top surface 171 of the battery cells 170 on the feeding mechanism 130 is damaged, as well as the location and depth of the damage.

[0079] As an implementation, see Figure 6As shown, bottom surface detection mechanism 160 includes a fourth horizontal motion assembly 161 and a fourth camera assembly 162. Fourth horizontal motion assembly 161 is connected to frame 100. The output end of fourth horizontal motion assembly 161 is connected to fourth camera assembly 162 to drive fourth camera assembly 162 to move in a first horizontal direction. When the loading robot grips battery cell 170, it first passes over bottom surface detection mechanism 160. After bottom surface detection mechanism 160 captures bottom surface 172 of battery cell 170, battery cell 170 is then placed on carrying platform 133.

[0080] The fourth imaging assembly 162 includes a fourth 2D camera and a fourth 3D camera. The fourth 2D camera is used to capture a two-dimensional image of the bottom surface 172 of the battery cell 170 on the loading robot, while the fourth 3D camera is used to capture a three-dimensional image of the bottom surface 172 of the battery cell 170 on the loading robot. The fourth 2D camera and the fourth 3D camera transmit the captured two-dimensional and three-dimensional images, respectively, to the control computer. The control computer analyzes the received two-dimensional and three-dimensional images to determine whether the bottom surface 172 of the battery cell 170 on the loading robot is damaged, as well as the location and depth of the damage.

[0081] As an implementation, see Figure 7 、 Figure 8 As shown, the six-sided inspection equipment for the appearance of a battery cell also includes a loading robot. The loading robot mechanism includes a loading robot arm 163, a first buffer 164, and a second clamping jaw assembly 165. The loading robot arm 163 is connected to the frame 100. The output end of the loading robot arm 163 is connected to the second clamping jaw assembly 165 to drive the second clamping jaw assembly 165 to clamp the battery cell 170 and place it on the feeding mechanism 130 to achieve the loading of the battery cell 170. The first buffer 164 is connected between the loading robot arm 163 and the second clamping jaw assembly 165 to provide buffering protection when the loading robot arm 163 drives the second clamping jaw assembly 165 to move. The loading robot arm 163 drives the second clamping jaw assembly 165 to move, clamps the battery cell 170 to be inspected above the bottom surface inspection mechanism 160, and photographs and inspects the bottom surface 172 of the battery cell 170, and places the battery cell 170 on the carrying platform 133 to complete the loading work. During loading, second gripper assembly 165 grips battery cell 170 and moves it above bottom surface detection mechanism 160. Loading robot arm 163 then drives second gripper assembly 165 to rest directly above fourth camera assembly 162. This captures and inspects bottom surface 172 of battery cell 170 held by second gripper assembly 165. After capturing the bottom surface 172 of battery cell 170, battery cell 170 is placed on carrying platform 133. The provision of first buffer member 164 improves equipment safety when loading robot arm 163 drives second gripper assembly 165 to move, thereby extending the service life of loading robot arm 163 and reducing maintenance costs.

[0082] As an embodiment, the six-sided inspection equipment for the appearance of a battery cell also includes a blanking robot. The blanking robot mechanism includes a blanking robot arm 166, a second buffer 167, and a third clamping assembly 168. The blanking robot arm 166 is connected to the frame 100. The output end of the blanking robot arm 166 is connected to the third clamping assembly 168 to drive the third clamping assembly 168 to clamp the battery cell 170 and move it away from the feeding mechanism 130 to achieve the blanking of the battery cell 170. The second buffer 167 is connected between the blanking robot arm 166 and the third clamping assembly 168 to provide buffering protection when the blanking robot arm 166 drives the third clamping assembly 168 to move. The blanking robot arm 166 drives the third clamping assembly 168 to move, clamping and moving the inspected battery cell 170 on the carrying platform 133 to the next station to complete the blanking work. The provision of the second buffer member 167 improves the equipment safety when the unloading robot arm 166 drives the third clamping jaw assembly 168 to move, thereby increasing the service life of the unloading robot arm 166 and reducing maintenance costs.

[0083] The following is the workflow of the six-side inspection equipment for battery cell appearance. A battery cell 170 includes a top surface 171, a bottom surface 172, a first side surface 173, a second side surface 174, a third side surface 175, and a fourth side surface 176. First, the loading robot grips the battery cell 170 to be inspected and carries it above the bottom surface inspection mechanism 160. The fourth 3D camera and the fourth 2D camera on the bottom surface inspection mechanism 160 then photograph the bottom surface 172 of the battery cell 170. The loading robot then places the battery cell 170 on the supporting platform 133 of the feeding mechanism 130. The first gripper assembly 131 grips the battery cell 170 on both sides of the supporting platform 133, stably placing it on the supporting platform 133. The second horizontal movement assembly 132 then drives the supporting platform 133 to move, causing the supporting platform 133 to move the battery cell 170 below the side inspection mechanism 110. In order to facilitate the side detection mechanism 110 to photograph the side of the battery cell 170, the first clamping jaw assembly 131 is opened at this time, and the negative pressure driving assembly 134 provides vacuum negative pressure for the adsorption hole 135, and the battery cell 170 on the carrying platform 133 is adsorbed on the carrying platform 133 through the negative pressure. At this time, the first horizontal moving assembly 101 and the first lifting assembly 102 drive the side detection mechanism 110 to move, so that the first shooting assembly and the second shooting assembly are respectively facing the first side 173 and the second side 174 of the battery cell 170, and photograph the first side 173 and the second side 174 of the battery cell 170. The rotating mechanism 140 then drives the carrying platform 133 to rotate the battery cell 170, so that the third side 175 and the fourth side 176 of the battery cell 170 are facing the first camera assembly and the second camera assembly, respectively. At this time, the first camera assembly and the second camera assembly move and adjust the distance to photograph and inspect the third side 175 and the fourth side 176 of the battery cell 170. After photographing and inspecting the third side 175 and the fourth side 176, the side inspection mechanism 110 moves to the other feeding mechanism 130 to prepare for photographing and inspecting. At this time, the first clamping assembly 131 re-clamps the battery cell 170 on the carrying platform 133, and the second horizontal moving assembly 132 drives the carrying platform 133 to move to the bottom of the top surface detection mechanism 150, so that the third shooting assembly 153 can shoot and detect the top surface 171 of the battery cell 170 on the carrying platform 133. After the shooting and detection are completed, the first clamping assembly 131 releases the battery cell 170, the negative pressure driving assembly 134 releases the vacuum negative pressure, and the unloading robot clamps the battery cell 170 on the carrying platform 133 and moves it away from the carrying platform 133, and sends the battery cell 170 to the next workstation.

[0084] To sum up, the six-sided inspection equipment for the appearance of battery cells provided in the present application performs photographing and inspection on a group of relative sides of the battery cell through the first shooting component and the second shooting component. The rotating mechanism 140 drives the side detection mechanism 110 and the feeding mechanism 130 to rotate relative to each other, so that the other group of relative sides of the battery cell are respectively facing the first shooting component and the second shooting component. At the same time, the first driving component drives the first shooting component and the second shooting component to move and change the spacing to quickly adapt to the other group of relative sides of the battery cell. In this way, by changing the relative position of the side detection mechanism 110 and the battery cell and adjusting the shooting spacing, the two shooting components can realize photographing and inspection of the four sides of the battery cell, which is beneficial to reducing the cost of the six-sided inspection equipment for the appearance of battery cells and improving the inspection efficiency of the battery cells.
