Description

Technical Field

[0001] The present invention relates to the field of lithium batteries, and in particular to a lithium battery alignment detection device. Background Art

[0002] Lithium batteries use lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution, hence the name lithium metal battery. Unlike other batteries, lithium batteries boast high charge density, long lifespan, and high unit cost. The tabs of lithium batteries are the parts that extend from the electrodes and connect to the other tabs for power to flow. Therefore, the integrity and alignment of the battery tabs are crucial inspection processes. However, optical inspection is not possible during lithium battery assembly. Therefore, X-ray inspection equipment is required to perform non-destructive testing to image the battery's interior.

[0003] The present applicant has found that when inspecting the alignment of lithium batteries, it is usually necessary to manually place the lithium batteries in an X-RAY inspection machine for inspection, which results in low inspection efficiency. Summary of the Invention

[0004] In view of this, the purpose of one or more embodiments of this specification is to propose a lithium battery alignment detection device to solve the technical problem in the prior art that when detecting the alignment of lithium batteries, it is usually necessary to manually place the lithium batteries in an X-RAY detection machine for detection, resulting in low detection efficiency.

[0005] Based on the above objectives, one or more embodiments of this specification provide a lithium battery alignment detection device, including:

[0006] An X-RAY inspection machine and a chain transmission device, wherein the chain transmission device passes through the X-RAY inspection machine;

[0007] A support plate and connecting blocks provided at both ends of the support plate, wherein a plurality of the support plates are distributed between two chains of a chain transmission device, and the connecting blocks are fixedly connected to the chain plates of the chain;

[0008] A first laser transmitter is provided on the outer surface of the support plate and a first laser receiver is provided in a detection head in an X-RAY detection machine, wherein the first laser receiver is electrically connected to the detection head in the X-RAY detection machine, and when the first laser receiver receives a signal from the first laser transmitter, the detection head in the X-RAY detection machine starts detection;

[0009] A second laser transmitter and a second laser receiver, wherein the second laser transmitter is disposed on the outer side of the support plate, and the second laser receiver is fixed in the housing of the X-RAY detector, and the second laser receiver is electrically connected to the detection head in the X-RAY detector;

[0010] an alarm installed on the gusset;

[0011] After the X-RAY inspection machine inspects the lithium battery on the support plate, if the alignment of the lithium battery is abnormal, the second laser transmitter starts to emit a signal, and after the second laser receiver receives the signal, the alarm sounds an alarm.

[0012] Furthermore, it also includes:

[0013] a through hole provided in the support plate, wherein the through hole passes through the upper and lower end surfaces of the support plate;

[0014] A support portion is provided in the side wall of the through hole. After the lithium battery is placed in the through hole, it is supported by the support portion. When the lithium battery is not placed in the through hole, the support portion shrinks into the side wall of the through hole.

[0015] When the second laser receiver receives the signal emitted by the second laser transmitter, the support portion shrinks into the side wall of the through hole, and another support plate is located directly below the support plate corresponding to the second laser transmitter.

[0016] Furthermore, the support portion includes:

[0017] A plurality of vertical grooves provided in the side walls of the through hole and transverse grooves passing through the vertical grooves, the vertical grooves passing through the upper surface of the support plate, and the transverse grooves passing through the side walls of the through hole and the outer surface of the support plate;

[0018] A support rod slidably connected to the transverse groove, the support rod being provided with an adjustment hole penetrating a side surface thereof;

[0019] The vertical rod passes through the adjustment hole and the first boss and the second boss are fixed on the side surface of the vertical rod. The vertical rod is located in the vertical groove. The first boss and the second boss are located on the symmetrical sides of the vertical rod and are staggered with each other. When the second boss is located in the adjustment hole, the front end of the support rod is located and extends into the through hole. When the first boss is located in the adjustment hole, the front end of the support rod is retracted into the horizontal groove.

[0020] The driving assembly is used to drive the support rod to move upward or downward.

[0021] Furthermore, it also includes a limiting plate located above the support rod, wherein the limiting plate is fixed to the side surface of the vertical rod and contacts the side wall of the vertical groove.

[0022] Furthermore, the driving component includes:

[0023] a circular ring located above the upper end surface of the support plate, wherein the circular ring is fixed to the upper end surface of the support plate by a fixing member;

[0025] Furthermore, it includes a cylinder fixed to the side plate of the chain transmission device, and when the second laser receiver receives the signal emitted by the second laser transmitter, the support plate corresponding to the second laser transmitter moves to just above the cylinder.

[0026] The beneficial effects of the present invention are as follows: using a lithium battery alignment detection device of the present invention, an operator places the lithium battery on a support plate, which is transmitted to the inside of an X-RAY detection machine through a chain transmission device. When the transmission is to the first laser receiver and receives a signal emitted by the first laser transmitter, the detection head in the X-RAY detection machine starts detection. If the lithium battery is qualified, the second laser transmitter will not emit a signal after the detection is completed. If the lithium battery is unqualified, the second laser transmitter will emit a signal after the detection is completed. After the detection is completed, the chain transmission device continues to transmit. If the second laser receiver receives a signal, it means that the alignment of the lithium battery on the support plate is unqualified. At this time, the alarm on the support plate will send a signal to remind the staff to deal with it. Through this device, the detection efficiency of the lithium battery alignment can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Based on the above purpose, the first aspect of the present invention provides an embodiment of a lithium battery alignment detection device, such as Figure 1 、 Figure 2 As shown, including:

[0036] An X-RAY inspection machine 1 and a chain transmission device, wherein the chain transmission device passes through the X-RAY inspection machine 1;

[0037] A support plate 4 and connecting blocks 9 provided at both ends of the support plate 4, wherein a plurality of the support plates 4 are distributed between two chains of a chain transmission device, and the connecting blocks 9 are fixedly connected to the chain plates of the chain;

[0038] A first laser emitter 5 is provided on the outer surface of the support plate 4, and a first laser receiver 6 is provided in the detection head of the X-RAY detection machine 1. The first laser receiver 6 is electrically connected to the detection head of the X-RAY detection machine 1. When the first laser receiver 6 receives a signal from the first laser emitter 5, the detection head of the X-RAY detection machine 1 starts detection.

[0039] A second laser emitter 7 and a second laser receiver 8. The second laser emitter 7 is disposed on the outer side of the support plate 4. The second laser receiver 8 is fixed in the housing of the X-RAY detector 1. The second laser receiver 8 is electrically connected to the detection head in the X-RAY detector 1.

[0040] An alarm provided on the support plate 4;

[0041] After the X-RAY inspection machine 1 inspects the lithium battery on the support plate 4, if the alignment of the lithium battery is abnormal, the second laser transmitter 7 starts to emit a signal, and after the second laser receiver 8 receives the signal, the alarm sounds an alarm.

[0042] In this embodiment, the operator places the lithium battery on the support plate 4 and transmits it to the inside of the X-RAY detection machine 1 through the chain transmission device. When it is transmitted to the first laser receiver 6 and receives the signal emitted by the first laser emitter 5, the detection head in the X-RAY detection machine 1 starts to detect. If the lithium battery is qualified, the second laser emitter 7 will not emit a signal after the detection is completed. If the lithium battery is unqualified, the second laser emitter 7 will emit a signal after the detection is completed. After the detection is completed, the chain transmission device continues to transmit. If the second laser receiver 8 receives the signal, it means that the alignment of the lithium battery on the support plate 4 is unqualified. At this time, the alarm on the support plate 4 will send a signal to remind the staff to deal with it. Through this device, the detection efficiency of the lithium battery alignment can be effectively improved.

[0043] As an implementation method, Figure 3 、 Figure 4 As shown, it also includes:

[0044] A through hole 14 is provided in the support plate 4, wherein the through hole 14 passes through the upper and lower end surfaces of the support plate 4;

[0045] The support portion is provided in the side wall of the through hole 14. After the lithium battery is placed in the through hole 14, it is supported by the support portion. When the lithium battery is not placed in the through hole 14, the support portion shrinks into the side wall of the through hole 14.

[0046] When the second laser receiver 8 receives the signal emitted by the second laser emitter 7 , the support portion shrinks into the side wall of the through hole 14 , and another support plate 4 corresponds to the support plate 4 corresponding to the second laser emitter 7 .

[0047] In this embodiment, after the lithium battery is placed in the through hole 14, it is supported by the support part. After the lithium battery inspection is completed, if the second laser receiver 8 receives the signal emitted by the second laser emitter 7, it indicates that the alignment of the lithium battery is unqualified. At this time, the support part shrinks to the side wall of the through hole 14, and the lithium battery will pass through the through hole 14 of the support plate 4 corresponding to the second laser emitter 7 and the through hole 14 of another support plate 4 directly below the support plate 4 corresponding to the second laser emitter 7, so that unqualified products can be eliminated.

[0048] As an implementation method, Figure 3 、 Figure 4 As shown, the support portion includes:

[0049] A plurality of vertical grooves 11 and transverse grooves 22 passing through the vertical grooves 11 are provided in the side walls of the through hole 14, wherein the vertical grooves 11 pass through the upper surface of the support plate 4, and the transverse grooves 22 pass through the side walls of the through hole 14 and the outer surface of the support plate 4;

[0050] A support rod 12 slidably connected to the transverse groove 22 , wherein the support rod 12 is provided with an adjustment hole 17 penetrating a side surface thereof;

[0051] The vertical rod 13 passes through the adjustment hole 17 and the first boss 15 and the second boss 16 are fixed to the side surface of the vertical rod 13. The vertical rod 13 is located in the vertical groove 11. The first boss 15 and the second boss 16 are located on the symmetrical sides of the vertical rod 13 and are staggered with each other. When the second boss 16 is located in the adjustment hole 17, the front end of the support rod 12 is located and extends into the through hole 14. When the first boss 15 is located in the adjustment hole 17, the front end of the support rod 12 is retracted into the transverse groove 22.

[0052] The driving assembly is used to drive the support rod 12 to move upward or downward.

[0053] In this embodiment, when the support plate 4 does not have a lithium battery placed thereon, the first boss 15 is located in the adjustment hole 17. At this time, the front end of the support rod 12 shrinks into the transverse groove 22. When the lithium battery is placed thereon, the driving assembly causes the support rod 12 to move downward. At this time, the second boss 16 gradually enters the adjustment hole 17, and the first boss 15 gradually separates from the adjustment hole 17. When the second boss 16 completely enters the adjustment hole 17, the front end of the support rod 12 extends into the through hole 14.

[0054] As an implementation method, Figure 4 As shown, it also includes a limit plate 18 located above the support rod 12. The limit plate 18 is fixed to the side surface of the vertical rod 13 and contacts the side wall of the vertical groove 11 to ensure the stability of the vertical rod 13 when moving upward and downward.

[0055] As an implementation method, Figure 4 As shown, the driving component includes:

[0056] A circular ring 19 is located above the upper end surface of the support plate 4, and the circular ring 19 is fixed to the upper end surface of the support plate 4 by a fixing member;

[0057] A first electromagnet 20 is fixed to the upper end surface of the vertical rod 13 , and a second electromagnet 21 corresponding to the first electromagnet 20 . The second electromagnet 21 is located directly above the corresponding first electromagnet 20 and is fixed to the ring 19 .

[0058] Here, when the first electromagnet 20 and the second electromagnet 21 generate a force that repels each other, the vertical rod 13 will move downward. When the first electromagnet 20 and the second electromagnet 21 generate a force that attracts each other, the vertical rod 13 will move upward.

[0059] As an implementation method, Figure 3 and Figure 4 As shown, the cylinder 10 includes a side plate fixed to the chain transmission device. When the second laser receiver 8 receives the signal emitted by the second laser emitter 7, the support plate 4 corresponding to the second laser emitter 7 moves to the top of the cylinder 10, ensuring that when the unqualified lithium battery falls, it will not be stuck between the two support plates 4.
