[0044] Please refer to Figures 1 to 8 Now, the multifunctional detection device 100 in the embodiment of the present invention is described.

[0045] Please refer to Figure 1 and Figure 3 ,For the convenience of description and understanding, the front-back direction, left-right direction, and up-down direction are defined.

[0046] Please refer to Figures 1 to 5 A multifunctional detection device 100 provided in the present application includes a workbench 20, a fixture 30, a code scanning device, a detection device, a conveying device 10 and a reflow device 200, the fixture 30 is used to fix the battery cell 40, the code scanning device is used to scan the QR code on the battery cell 40, the detection device is used to test the battery cell 40, the conveying device 10 has a first station 11, a second station 12, a third station 13 and a fourth station 14 arranged in sequence, the conveying device 10 is used to convey the fixture 30 to the first station 11, the second station 12, the third station 13 and the fourth station 14 in a horizontal direction, the reflow device 200 includes a conveying mechanism 21, a first pushing mechanism 22 and a second pushing mechanism 23, the conveying mechanism 21 and the conveying device 10 are arranged side by side for conveying the fixture 30.

[0047] Among them, the code scanning device, the detection device, the conveying device 10 and the conveying mechanism 21 are all arranged on the workbench 20, one of the first station 11 and the fourth station 14 is a loading station, and the other is an unloading station, one of the second station 12 and the third station 13 is equipped with a code scanning device, and the other is equipped with a detection device.

[0048] The conveying mechanism 21 has a return line station 214 arranged opposite to the loading station, and a reflow station 211 arranged opposite to the unloading station. The first pushing mechanism 22 is arranged on the side of the unloading station away from the reflow station 211, and is used to push the fixture 30 located on the unloading station to the reflow station 211. The second pushing mechanism 23 is arranged on the side of the return line station 214 away from the loading station, and is used to push the fixture 30 located on the return line station 214 to the loading station.

[0049] The first station 11, the second station 12, the third station 13 and the fourth station 14 extend in the front-to-back direction, the conveying device 10 and the conveying mechanism 21 are arranged side by side in the left-to-right direction, and the conveying device 10 is located on the left side of the conveying mechanism 21, and the conveying direction of the conveying device 10 and the conveying direction of the conveying mechanism 21 are parallel to the front-to-back direction.

[0050] It should be noted that the first station 11 can be a loading station or a unloading station. Similarly, the fourth station 14 can be an unloading station or a loading station. As long as one of them is a loading station and the other is an unloading station, it will be fine. The code scanning device can be configured at the second station 12 or the third station 13. Similarly, the detection device can be configured at the third station 13 or the second station 12. As long as they are not configured at the same station, it is fine.

[0051] For example, in some embodiments, the first station 11, the second station 12, the third station 13 and the fourth station 14 are respectively a loading station, a code scanning device, a detection device and a material unloading station. For another example, in some technical solutions, the first station 11, the second station 12, the third station 13 and the fourth station 14 are respectively a material unloading station, a code scanning device, a detection device and a material loading station. It can be seen that the battery cell 40 can be scanned first and then detected, or it can be detected first and then scanned.

[0052] Here, for the convenience of description and understanding, the first station 11, the second station 12, the third station 13 and the fourth station 14 are respectively used as the loading station, the scanning device, the detection device and the unloading station for explanation. During operation, the battery cell 40 to be tested is placed in the jig 30 located at the first station 11, and the conveying device 10 transports the jig 30 carrying the battery cell 40 to the second station 12, and the scanning device scans the battery cell 40. Then the conveying device 10 transports the battery cell 40 after the scanning operation to the third station 13, and the detection device performs voltage or internal resistance detection on the battery cell 40. After the detection is completed, the conveying device 10 transports the jig 30 to the fourth station 14, and the battery cell 40 on the jig 30 is removed by a manual or automated structure (such as a manipulator). After the battery cell 40 is taken away, the first pushing mechanism 22 pushes the jig 30 to the reflow station 211 of the conveying mechanism 21. Driven by the conveying mechanism 21, the jig 30 moves to the return line station 214, and then the second pushing mechanism 23 pushes the jig 30 to the loading station of the conveying device 10. In this way, the jig 30 is moved from the unloading station of the conveying device 10 to the loading station of the conveying device 10 by mechanical automation, which greatly reduces the consumption of labor.

[0053] In addition, in the present application, by setting up a code scanning device, the battery cell 40 to be tested can be scanned, so that the test value and the code value can be bound and uploaded to the cloud, which can facilitate later traceability. If there is a problem with the product later, it can be returned for repair. In this way, the multifunctionality of the battery cell 40 detection device is realized, and the practicality of the multifunctional detection device 100 is greatly improved.

[0054] In another embodiment of the present application, please refer to Figure 2 and Figure 3 The reflow station 211 is provided with a first lifting driving member 212 and a first jig carrying plate 213 , and the first lifting driving member 212 is drivingly connected to the first jig carrying plate 213 so that the first jig carrying plate 213 moves in the up and down direction.

[0055] Specifically, the unloading station is located on the left side of the reflow station 211, and the first pushing mechanism 22 is located on the left side of the unloading station. When the jig 30 moves to the unloading station and the battery cell 40 on the jig 30 is removed, the first lifting drive member 212 drives the first jig carrier plate 213 to move it upward. Then the first pushing mechanism 22 pushes the jig 30 located at the unloading station onto the first jig carrier plate 213, and then the first pushing mechanism 22 and the first lifting drive member 212 are reset, so that the jig 30 is supported on the conveying mechanism 21, so that the conveying mechanism 21 can drive the jig 30 to move. The setting of the first lifting drive member 212 and the first jig carrier plate 213 can reduce the influence of the conveying mechanism 21 on the jig 30 during the process of being pushed by the first pushing mechanism 22, thereby reducing the degree of skewness of the jig 30, which is beneficial to improving the detection effect of the battery cell 40.

[0056] In another embodiment of the present application, please refer to Figure 1 The unloading station is provided with an unloading support plate 50 for supporting the jig 30, and the first lifting drive member 212 is drivingly connected to the unloading support plate 50 so as to move the unloading support plate 50 in the up-down direction. When the jig 30 moves to the unloading station and the battery cell 40 on the jig 30 is removed, the first lifting drive member 212 simultaneously drives the first jig carrier plate 213 and the carrier plate to move upward, so that the jig 30 is separated from the conveying device 10 and the conveying mechanism 21 during the entire pushing process, further improving the detection effect of the battery cell 40.

[0057] Of course, in some other embodiments, the blanking support plate 50 may be independently driven by another driving member, and not controlled by the first lifting driving member 212, which is not limited here.

[0058] In another embodiment of the present application, the return line station 214 is provided with a second lifting driving member and a second jig supporting plate, and the second lifting driving member is drivingly connected to the second jig supporting plate to move the second jig supporting plate in the up and down directions.

[0059] Specifically, the loop station 214 is located on the right side of the loading station, and the second pushing mechanism 23 is located on the right side of the loop station 214. After the conveying mechanism 21 conveys the jig 30 to the loop station 214, the second lifting drive member drives the second jig carrier plate to make it rise, and then the second pushing mechanism 23 pushes the jig 30 supported on the second jig carrier plate to the loading station of the conveying device 10, and then the second pushing mechanism 23 and the second lifting drive member are reset. The provision of the second lifting drive member and the second jig carrier plate can reduce the influence of the conveying mechanism 21 on the jig 30 during the process of being pushed by the second pushing mechanism 23, thereby reducing the degree of skewness of the jig 30, which is beneficial to improving the detection effect of the battery cell 40.

[0060] In another embodiment of the present application, please refer to Figure 1 The loading station is provided with a loading support plate 60 for supporting the jig 30, and the second driving member 121 is drivingly connected to the loading support plate 60 so as to move the loading support plate 60 in the up-down direction. When the jig 30 moves to the return line station 214, the second lifting driving member simultaneously drives the second jig carrier plate and the carrier plate to move upward, so that the jig 30 is separated from the conveying device 10 and the conveying mechanism 21 during the entire pushing process, further improving the detection effect of the battery cell 40.

[0061] Of course, in some other embodiments, the loading support plate 60 may be independently driven by another driving member, rather than being controlled by the second lifting driving member, which is not limited here.

[0062] It is understandable that the first lifting drive member 212 and the second lifting drive member can be cylinders, linear motor modules, or hydraulic rods, which are not limited here.

[0063] In another embodiment of the present application, please refer to Figure 2 The reflow station 211 is provided with a first fixture sensor 215 for sensing the fixture 30. Specifically, the first fixture sensor 215 is a proximity switch, and when the first fixture sensor 215 senses that there is a fixture 30 on the reflow station 211, the first lifting driving member 212 is reset.

[0064] In another embodiment of the present application, please refer to Figure 2 , the first jig sensor 215 is located below the first jig carrier plate 213, the first jig carrier plate 213 is provided with a first avoidance groove 2131, and the first jig sensor 215 is exposed in the first avoidance groove 2131. Specifically, the first avoidance groove 2131 is provided on the upper surface of the first jig carrier plate 213, and penetrates the lower surface of the first jig carrier plate 213 in the up-down direction. The first jig sensor 215 is located directly below the first avoidance groove 2131. This arrangement enables the first jig sensor 215 to sense the jig 30 pushed onto the first jig carrier plate 213.

[0065] In another embodiment of the present application, the return line station 214 is provided with a second fixture sensor for sensing the fixture 30. Specifically, the second fixture sensor is a proximity switch, and when the second fixture sensor senses that there is a fixture 30 on the return line station 214, the second lifting drive member drives the second fixture carrier plate to rise, so that the fixture 30 is separated from the conveying mechanism 21.

[0066] In another embodiment of the present application, the second jig sensor is located below the second jig carrier plate, the second jig carrier plate is provided with a second avoidance groove, and the second jig sensor is exposed in the second avoidance groove. Specifically, the second avoidance groove is provided on the upper surface of the second jig carrier plate and penetrates the lower surface of the second jig carrier plate in the up-down direction. The second jig sensor is located directly below the second avoidance groove, and is arranged in this way so that the second jig sensor can sense the jig 30 located on the return line station 214.

[0067] In another embodiment of the present application, please refer to Figure 2 and Figure 3 The first pushing mechanism 22 includes a first pushing driving member 221, a first pushing member 222 and a first limiting member 223. The first pushing member 222 is located on the side of the unloading station away from the reflow station 211. The first limiting member 223 is located on the side of the reflow station 211 away from the unloading station. The first pushing driving member 221 is drivingly connected to the first pushing member 222.

[0068] Specifically, the first push driving member 221 is a rodless cylinder, and the movable end of the first push driving member 221 moves in the left-right direction. The first push member 222 is located on the left side of the unloading station and is fixedly installed on the movable end of the first push driving member 221. The movable end of the first push driving member 221 drives the first push member 222 to make linear reciprocating motion in the left-right direction. The first limiting member 223 is located on the right side of the reflow station 211. The first pushing member 222, driven by the first push driving member 221, pushes the jig 30 to the right until the jig 30 abuts against the first limiting member 223. The setting of the first limiting member 223 can ensure that the jig 30 can reach a suitable position.

[0069] In another embodiment of the present application, the second pushing mechanism 23 includes a second pushing drive member, a second pushing member and a second limiting member. The second pushing member is located on the side of the return line station 214 away from the loading station. The second limiting member is located on the side of the loading station away from the return line station 214. The second pushing drive member is drivingly connected to the second pushing member.

[0070] Specifically, the second push-driving member is a rodless cylinder, and the movable end of the second push-driving member moves in the left-right direction. The second pusher is located on the right side of the return line station 214, and is fixedly mounted on the movable end of the second pusher. The movable end of the second pusher drives the second pusher to perform linear reciprocating motion in the left-right direction. The second limiting member is located on the left side of the loading station, and the second pushing member, driven by the second pusher, pushes the jig 30 to the left until the jig 30 abuts against the second limiting member. The setting of the second limiting member can ensure that the jig 30 can reach a suitable position.

[0071] In another embodiment of the present application, please refer to Figures 4 to 6The first station 11 is provided with a first battery cell sensor 111, a first fixture stopper 112 and a first driving member 113. The first battery cell sensor 111 is installed on the workbench 20 and is used to sense the battery cell 40. The first driving member 113 is installed on the workbench 20 and is driven and connected to the first fixture stopper 112 to move the first fixture stopper 112 in the up and down directions. The first fixture stopper 112 is located between the first station 11 and the second station 12.

[0072] Specifically, in this embodiment, the first station 11 is a loading station. The first battery cell sensor 111 is located on the side of the first station 11 away from the second station 12. The first battery cell sensor 111 can be a reflective photoelectric sensor or a laser sensor, which is not limited here. The first driving member 113 can be a linear motor module, a cylinder, or a hydraulic rod, as long as it can adjust the position of the first fixture stopper 112 in the up and down directions, which is not limited here.

[0073] Before placing the battery cell 40 to be tested, the first driving member 113 drives the first jig stopper 112 to move it upward. The first jig stopper 112 is used to block the jig 30 located at the first station 11 to facilitate manual or automatic loading. When the battery cell 40 to be tested is assembled on the jig 30, the first battery cell sensor 111 senses the battery cell 40 to be tested, and the first driving member 113 drives the first jig stopper 112 to descend, so that the jig 30 can be transported to the second station 12 by the conveying device 10.

[0074] In this embodiment, the first driving member 113 is a cylinder. Of course, in some other embodiments, the first driving member 113 may be a linear motor module or a hydraulic rod, etc., which is not limited here.

[0075] In another embodiment of the present application, please refer to Figure 7 and Figure 8 The second workstation 12 is provided with a second driving member 121, a third driving member 122 and two first clamping assemblies 123. The second driving member 121 and the third driving member 122 are both installed on the workbench 20. The second driving member 121 and the third driving member 122 are respectively driven and connected to the two first clamping assemblies 123, wherein the two first clamping assemblies 123 are used to clamp the fixture 30 together.

[0076] Specifically, among the two first clamping assemblies 123, one of the first clamping assemblies 123 is located on the side of the second station 12 close to the first station 11, and the other first clamping assembly 123 is located on the side of the second station 12 close to the third station 13. In the present application, the second driving member 121 is drivingly connected to the first clamping assembly 123 close to the first station 11, and the third driving member 122 is drivingly connected to the first clamping assembly 123 close to the third station 13. During operation, the third driving member 122 drives the first clamping assembly 123 to make it rise, and the first clamping assembly 123 is used to block the jig 30 and make the jig 30 stay on the second station 12. When the jig 30 abuts against the first clamping assembly 123 close to the third station 13, the second driving member 121 drives the other first clamping assembly 123 to make it close to the jig 30. Finally, the two first clamping assemblies 123 clamp the jig 30 together. Such a configuration can improve the stability of the fixture 30, so as to facilitate the scanning device to scan the battery cell 40, or facilitate the detection device to test the battery cell 40, which is conducive to improving the accuracy of the test results.

[0077] In another embodiment of the present application, please refer to Figure 7 and Figure 8 The first clamping assembly 123 includes a first mounting seat 1231 and a first fixture clamp 1232. The first mounting seat 1231 is installed on the workbench 20. The first fixture clamp 1232 is hinged to the first mounting seat 1231. The second driving member 121 is hinged to the first fixture clamp 1232 of one of the first clamping assemblies 123. The third driving member 122 is hinged to the first fixture clamp 1232 of the other first clamping assembly 123.

[0078] Specifically, in this embodiment, the telescopic end of the second driving member 121 and the telescopic end of the third driving member 122 are both telescopic in the front-to-back direction. The third driving member 122 is drivingly connected to one end of one of the first fixture clamps 1232, and the third driving member 122 drives one end of the first fixture clamp 1232. Since the first fixture clamp 1232 is hinged with the corresponding first mounting seat 1231, the other end of the first fixture clamp 1232 rises or falls, thereby realizing the limiting or release of the fixture 30 located on the second station 12.
