[0002] With the rapid development of the new energy field, the manufacturing process of lithium batteries is also constantly improving, placing increasingly higher demands on manufacturing precision and quality pass rate. Specifically, the current collector of the battery cell is welded to the bottom wall of the casing, forming a weld mark on the outer surface of the casing. If the welding quality at this point is poor, the negative electrode tab of the electrode assembly will not be able to make electrical connection with the outside, leading to the failure of the battery cell.

[0003] To inspect the welding quality between the current collector and the casing, the conventional method is to use a CCD camera to photograph the bottom of the casing and judge the welding quality by detecting the shape of the weld marks. However, the current weld mark inspection equipment has poor detection accuracy, resulting in poor reliability of individual battery cells. Utility Model Content

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0034] like Figure 1 , Figure 3 , Figure 6 and Figure 9 As shown, the solder mark inspection device 100 of some embodiments of this application includes a pressing device 110, a solder mark inspection device 120, and an lifting device 130. The pressing device 110 includes a pressing conveying mechanism 111 and a pressing assembly 112. The pressing conveying mechanism 111 is used to convey the battery cell 210 with the cup holder 220, and the pressing assembly 112 is used to press down the battery cell 210. The solder mark detection device 120 is located downstream of the pressing device 110 and includes a detection conveying mechanism 121 and a vision detection mechanism 122. The detection conveying mechanism 121 is used to convey the battery cell 210 with the cup holder 220, and the vision detection mechanism 122 is configured to detect whether the solder mark on the bottom wall 211 of the battery cell 210 is qualified. The lifting device 130 is located downstream of the solder mark detection device 120 and includes a lifting conveying mechanism 131 and a lifting assembly 132. The lifting conveying mechanism 131 is used to convey the battery cell 210 with the cup holder 220, and the lifting assembly 132 is used to lift the battery cell 210.

[0035] It is understandable that the workpiece processed by the solder mark inspection equipment 100 is a battery cell 210 with a cup holder 220. The battery cell 210 is inserted into the cup holder 220 in the vertical direction Z, and the two form an assembly 200. Figure 2 As shown, the battery cell 210 includes a bottom wall 211, a top wall 212 and an outer peripheral wall 213. The bottom wall 211 and the top wall 212 are arranged opposite each other in the vertical direction Z. Since the battery cell 210 is not yet sealed, the top wall 212 refers to the opening of the casing.

[0036] The solder mark inspection device 100 of this application embodiment includes a pressing device 110 and an lifting device 130. The pressing device 110 and the lifting device 130 are respectively disposed upstream and downstream of the solder mark inspection device 120. The pressing device 110 presses down the battery cell 210 to a preset inspection height position. After the solder mark inspection is completed, the lifting device 130 lifts the battery cell 210 back to its original height position. Since the bottom wall 211 of the pressed battery cell 210 is closer to the vision inspection mechanism 122, the inspection accuracy of the vision inspection mechanism 122 on the solder mark quality can be improved, thereby improving the quality control management level of the battery cell 210 and improving the quality reliability of the battery cell 210.

[0037] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of this application, the pressure conveying mechanism 111 includes a pressure conveying assembly 113 and a pressure fixture 115. The pressure conveying assembly 113 is used to drive the pressure fixture 115 to move, and the pressure fixture 115 is used to hold the cup holder 220.

[0038] The pressing and conveying assembly 113 includes a rotation drive assembly and a cam turntable. The central axis of the cam turntable is a first axis P, which is parallel to the vertical direction Z. Multiple pressing fixtures 115 are provided. The pressing and conveying mechanism 111 also includes multiple pressing supports 114, with each pressing fixture 115 mounted on a corresponding pressing support 114. The cam turntable includes a first groove extending around the first axis P, and the pressing supports 114 are mounted in the first groove of the cam turntable. The rotation drive assembly drives the multiple pressing supports 114 to rotate around the first axis P. The rear part of the pressing support 114 slides along the first groove, and drives the corresponding pressing fixtures 115 to move synchronously.

[0039] With this configuration, the pressure jig 115 can be moved simply and reliably to convey the battery cell 210 with cup holder 220.

[0040] In other embodiments, the pressure delivery assembly 113 may also deliver the battery cell 210 with cup holder 220 in a straight direction.

[0041] like Figure 4 and Figure 5 As shown, in some embodiments of this application, the pressing fixture 115 includes a side clamping part 1151 and a bottom support plate 1152. The side clamping part 1151 is used to clamp the outer peripheral surface of the cup holder 220, and the bottom support plate 1152 is disposed on the lower side of the side clamping part 1151 for receiving the battery cell 210.

[0042] The bottom support plate 1152 is disposed below the side clamping part 1151 along the vertical direction Z. The projection of the bottom wall 211 of the battery cell 210 on the XY plane falls into the bottom support plate 1152. The bottom support plate 1152 supports a portion of the bottom surface of the battery cell 210 and the cup holder 220. The side clamping part 1151 can be a vacuum gripper or other types of grippers. The outer peripheral surface of the cup holder 220 refers to the surface of the cup holder 220 that extends circumferentially around the axis of the battery cell 210. The axis of the battery cell 210 is parallel to the vertical direction Z.

[0043] With this configuration, the assembly 200 can be supported from the bottom, the pressure jig 115 can hold the cup holder 220, and the battery cell 210 can be prevented from falling out of the cup holder 220 during the pressing process.

[0044] In other embodiments, a corresponding operating surface can also be provided to support the cup holder 220, which slides on the operating surface and receives the battery cell 210.

[0045] like Figure 4 and Figure 5 As shown, in some embodiments of this application, the pressing conveying mechanism 111 further includes a pressing bracket 114, the pressing conveying assembly 113 is used to drive the pressing bracket 114 to move, the pressing fixture 115 is disposed on the pressing bracket 114, and the pressing assembly 112 includes a first sliding bracket 1121 and a pressing rod 1122. The first sliding bracket 1121 is slidably engaged with the pressing bracket 114, and the pressing rod 1122 is disposed on the pressing bracket 114. The pressing rod 1122 can move downward to press the battery cell 210 down to the detection height position.

[0046] The pressure rod 1122 abuts downward against the top wall 212 of the battery cell 210 to press the battery cell 210 downward. Based on the aforementioned embodiment where the top wall 212 of the battery cell 210 is an opening of the housing, the end of the pressure rod 1122 has a groove, which can avoid the exposed parts outside the housing while abutting against the annular opening.

[0047] The first sliding bracket 1121 and the lowering bracket 114 slide together along the first axis P. The cam turntable of the lowering conveying assembly 113 is provided with a second sliding groove. The second sliding groove is located on the upper side of the first sliding groove. A portion of the second sliding groove extends towards the first sliding groove. The first sliding bracket 1121 is mounted on the second sliding groove via rollers. As the first sliding bracket 1121 moves along the second sliding groove, it moves downward to drive the pressure rod 1122 to move downward.

[0048] As an example, the downward stroke of the pressure rod 1122 along the vertical direction Z is 1mm. By adopting the implementation of a cam turntable and a second slide groove, the stroke range can be shortened and the vibration of the pressure rod 1122 during the lifting and lowering process can be reduced, so as to achieve smooth downward pressure on the battery cell 210.

[0049] With this configuration, the pressure rod 1122 can be moved downwards in a simple and reliable manner, pressing the battery cell 210 down to the preset detection height position.

[0050] In other embodiments, each pressure bar 1122 may also be provided with an independent lifting drive.

[0051] like Figure 6 , Figure 7 and Figure 8As shown, in some embodiments of this application, the detection conveying mechanism 121 includes a detection conveying component 123 and a detection fixture 124. The detection conveying component 123 is used to drive the detection fixture 124 to move, and the detection fixture 124 is used to hold the cup holder 220.

[0052] The inspection conveying assembly 123 includes a drive turntable, the central axis of which is the second axis Q extending vertically in the Z direction. Multiple inspection fixtures 124 are provided, and the multiple inspection fixtures 124 are arranged circumferentially around the second axis Q. The inspection fixtures 124 clamp the outer peripheral surface of the cup holder 220 without obstructing the bottom wall 211 of the battery cell 210, so that the visual inspection mechanism 122 can take pictures and inspect the bottom wall 211 of the battery cell 210.

[0053] The vision inspection mechanism 122 is set around the drive turntable. When the inspection fixture 124 carrying the corresponding battery cell 210 passes through the vision inspection mechanism 122, the vision inspection mechanism 122 takes pictures to inspect the soldering quality of the battery cell 210.

[0054] This configuration allows for simple and reliable movement of the battery cell 210 with cup holder 220 around the second axis Q, efficiently completing the soldering inspection process.

[0055] In other embodiments, the detection conveying mechanism 121 may also convey the battery cell 210 with cup holder 220 in a straight direction.

[0056] like Figure 8 As shown, in some embodiments of this application, the solder stamp inspection device 120 further includes a protective plate 125, an inspection fixture 124 is disposed on the upper side of the protective plate 125, a visual inspection mechanism 122 is disposed on the lower side of the protective plate 125, and the area of ​​the protective plate 125 corresponding to the visual inspection mechanism 122 is a transparent area 1251.

[0057] The thickness direction of the protective plate 125 extends along the vertical direction Z. The inspection fixture 124 is disposed on the upper side of the protective plate 125 along the vertical direction Z. The visual inspection mechanism 122 is disposed on the lower side of the protective plate 125 along the vertical direction Z.

[0058] With this configuration, the lower vision inspection mechanism 122 can be protected during the conveying of the battery cell 210 with cup holder 220, preventing the battery cell 210 with cup holder 220 from falling off and damaging the lower vision inspection mechanism 122.

[0059] In some embodiments of this application, multiple visual inspection mechanisms 122 are provided, and the multiple visual inspection mechanisms 122 are spaced apart along the conveying direction of the pressing conveyor 111.

[0060] For example, four visual inspection mechanisms 122 are provided, and the four visual inspection mechanisms 122 are arranged circumferentially around the drive turntable. The protective plate 125 includes four transparent areas 1251, and the visual inspection mechanism 122 corresponds one-to-one with the transparent area 1251.

[0061] This setup allows for the photographic inspection of multiple battery cells 210 in a single cycle, improving the efficiency of solder mark inspection.

[0062] In other embodiments, the number of visual inspection units 122 may also be one, two, five, etc.

[0063] like Figure 6 and Figure 7 As shown, in some embodiments of this application, the solder mark detection device 120 further includes a marking mechanism 126, which is used to mark information codes on the surface of the battery cell 210.

[0064] The marking mechanism 126 is arranged around the drive turntable. The light outlet of the marking mechanism 126 is located on the upper side of the protective plate 125. When the detection fixture 124 carries the corresponding battery cell 210 past the marking mechanism 126, the marking mechanism 126 marks the information code on the outer peripheral wall 213 of the battery cell 210. There are two marking mechanisms 126, which are arranged at intervals around the drive turntable.

[0065] This configuration allows for the integration of marking functions into the solder mark inspection device 120, thereby improving the processing efficiency of the battery cell 210.

[0066] like Figure 6 and Figure 7 As shown, in some embodiments of this application, the marking mechanism 126 includes a marking component 1261, a protective cover 1262, and a dust cover 1263. The marking component 1261 is used to mark information codes on the surface of the battery cell 210. The protective cover 1262 is located near the light outlet of the marking component 1261, and the dust cover 1263 is located near the light outlet.

[0067] The marking assembly 1261 includes a marking bracket 1264 and a marking machine 1265. The marking machine 1265 has a light emission port, from which it emits a laser to mark information codes on the surface of the battery cell 210. The marking machine 1265, a protective cover 1262, and a dust removal cover 1263 are all mounted on the marking bracket 1264. The protective cover 1262 covers the upper side of the light emission port. The dust removal port of the dust removal cover 1263 is located near the light emission port. The dust removal cover 1263 is connected to a negative pressure supply device, which provides a negative pressure environment near the light emission port to remove dust generated during the marking process.

[0068] This design reduces interference from other light sources at the light outlet to the marking laser via the protective cover 1262 and prevents foreign objects from falling into the laser path; the dust cover 1263 purifies the marking environment, thereby improving marking quality.

[0069] As a preferred embodiment, the dust removal port of the dust removal hood 1263 is located on the upper side of the protective plate 125, which not only improves the dust removal effect but also facilitates maintenance.

[0070] like Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments of this application, the top conveying mechanism 131 includes a top conveying component 133 and a top fixture 135. The top conveying component 133 is used to drive the top fixture 135 to move, and the top fixture 135 is used to hold the cup holder 220.

[0071] The upper conveying assembly 133 includes a rotation drive assembly and a cam turntable. The central axis of the cam turntable is a third axis N, which is parallel to the vertical direction Z. The upper conveying assembly 133 has a similar structure and working principle to the lower conveying assembly 113, and will not be described further here.

[0072] The top mounting fixture 135 includes a top pressure plate 1351, side grippers 1352, and a cup holder plate 1353. The top pressure plate 1351 is located above the side grippers 1352, and the cup holder plate 1353 is located below the side grippers 1352. The cup holder plate 1353 supports the bottom surface of the cup holder 220, and the side grippers 1352 clamp the outer peripheral surface of the cup holder 220. The top pressure plate 1351 is used to press down the top surface of the cup holder 220 to prevent the cup holder 220 from moving upward together with the battery cell 210 during the process of mounting the battery cell 210.

[0073] With this configuration, the upper jig 135 can be moved simply and reliably to transport the battery cell 210 with cup holder 220.

[0074] In other embodiments, the top conveying assembly 133 may also convey the battery cell 210 with cup holder 220 in a straight direction.

[0075] like Figure 10 and Figure 11 As shown, in some embodiments of this application, the upper conveying mechanism 131 further includes an upper support 134, the upper conveying assembly 133 is used to drive the upper support 134 to move, the upper fixture 135 is disposed on the upper support 134, the upper assembly 132 includes a second sliding support 1321 and a top rod 1322, the second sliding support 1321 is slidably engaged with the upper support 134, the top rod 1322 is disposed on the upper support 134, and the top rod 1322 can move upward to reset the battery cell 210.

[0076] The second sliding bracket 1321 and the upper top bracket 134 are slidably engaged along the third axis N. The second sliding bracket 1321 and the upper top bracket 134 are respectively installed in different grooves of the cam turntable. The upper top bracket 134 is driven to rise and fall in the vertical direction Z by the change of the extension direction of the groove. The lifting and lowering drive method of the push rod 1322 is similar to that of the pressure rod 1122, and will not be described further here.

[0077] Understandably, the upper jig 135 clamps the cup holder 220 while exposing the bottom wall 211 of the battery cell 210 so that the top rod 1322 can abut against the bottom wall 211 of the battery cell 210.

[0078] With this configuration, the top rod 1322 can be moved upwards in a simple and reliable manner, so as to reset the battery cell 210 to its original height position.

[0079] In other embodiments, each top rod 1322 may also be provided with an independent lifting drive.

[0080] like Figure 1 As shown, in some embodiments of this application, the solder mark inspection device 100 further includes a barcode scanning device 140, which is located upstream of the pressing device 110, for reading the information code of the cup holder 220 corresponding to the battery cell 210.

[0081] For example, the scanning device 140 includes a first scanning turntable 141 and a second scanning turntable 142 arranged in sequence, which perform odd-number scanning and even-number scanning respectively to adapt to the rhythm arrangement.

[0082] With this setup, the information code of the cup holder 220 can be read before the soldering inspection. The visual inspection mechanism 122 feeds back the soldering inspection result to the control device. The control device associates the information code of the soldering inspection mechanism with the corresponding cup holder 220 of the battery cell 210, so that the subsequent process will reject the unqualified battery cell 210 as NG.

[0083] like Figure 1 As shown, in some embodiments of this application, the solder mark inspection device 100 further includes an infeed turntable 150, an outfeed turntable 160, and an intermediate turntable 170.

[0084] The feeding turntable 150 is located upstream of the barcode scanner 140 and is used to receive battery cells 210 with cup holders 220 and transfer them to the barcode scanner 140. Multiple proximity sensors 151 are arranged around the periphery of the feeding turntable 150. When all adjacent proximity sensors 151 detect a workpiece passing by, the solder mark detection equipment 100 is determined to be in normal working condition, and the pressing device 110, solder mark detection device 120, and lifting device 130 operate normally. When at least one of the adjacent proximity sensors 151 fails to detect a workpiece passing by, the solder mark detection equipment 100 is determined to be in abnormal working condition, and the machine is stopped for manual troubleshooting.

[0085] The discharge turntable 160 is located downstream of the upper device 130 and is used to receive the battery cells 210 with cup holders 220 that have passed the solder mark inspection and to discharge them.

[0086] An intermediate turntable 170 is provided between the second scanning turntable 142 and the pressing device 110, and an intermediate turntable 170 is provided between the lifting device 130 and the discharge turntable 160. By setting the intermediate turntable 170, it is convenient to adjust the direction and rhythm of the battery cell 210 and connect the two adjacent devices.

[0087] like Figure 1 As shown, in some embodiments of this application, the solder mark inspection device 100 further includes a feeding channel 180, the bottom of which is provided with a magnetic strip, and the feeding channel 180 is located upstream of the feeding turntable 150.

[0088] This configuration reduces the vibration of the battery cells 210 during feeding, and guides the battery cells 210 with cup holders 220 to enter the feeding turntable 150 smoothly and reliably.

[0089] like Figures 1 to 11 As shown, the working principle of the solder mark inspection device 100 in this application embodiment is as follows:

[0090] The battery cell 210 with cup holder 220 enters the feeding turntable 150 through the feeding channel 180, and after passing through the first barcode turntable 141 and the second barcode turntable 142, it enters the pressing device 110.

[0091] The pressing fixture 115 clamps the cup holder 220, and the pressing conveying assembly 113 drives multiple pressing fixtures 115 to rotate around the first axis P. The pressing rod 1122 moves downward under the action of the cam turntable, pressing the battery cell 210 down to the preset detection height position.

[0092] The inspection fixture 124 receives the assembly 200 after it is pressed down. The inspection conveying component 123 drives the inspection fixture 124 to rotate around the second axis P. When the assembly 200 passes the vision inspection mechanism 122, the vision inspection mechanism 122 takes a picture of the bottom wall 211 of the battery cell 210 to inspect the soldering quality. When the assembly 200 passes the marking mechanism 126, the marking machine 1265 marks the information code on the outer peripheral wall 213 of the battery cell 210.

[0093] The upper jig 135 receives the assembly 200 that has been inspected and marked with solder marks. The upper jig 135 rotates around the third axis N under the drive of the upper conveying component 133. The push rod 1322 pushes upward under the action of the cam turntable, pushing the battery cell 210 upward, so that the battery cell 210 returns to its original height position.

[0094] The assembly 200 passes through the intermediate turntable 170 and the discharge turntable 160 in sequence before being discharged.

[0095] The solder mark inspection equipment 100 of this application embodiment can first press the battery cell 210 down to a preset inspection height position, complete the solder mark inspection process and the marking process on the stroke of the drive turntable of the solder mark inspection device 120, and then push the battery cell 210 back up and discharge it. This not only improves the solder mark inspection accuracy and the quality reliability of the battery cell 210, but also integrates the marking process, thereby improving the processing efficiency of the battery cell 210.
