Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery detection, and particularly to a detection device for lithium battery assembly. Background Art

[0002] With the rapid development of portable electronic devices, electric vehicles, and energy storage systems, the demand for lithium batteries is increasing day by day. As one of the key components, the performance and quality of lithium batteries are directly related to the safety of the final products and the user experience. Therefore, in the production process of lithium batteries, it is crucial to ensure the quality of each battery cell. Among them, voltage and internal resistance are important parameters to measure the performance of lithium batteries. To ensure that these parameters meet the specification requirements, detection has become an indispensable part of the production process.

[0003] When traditional lithium battery assembly production lines perform voltage and internal resistance detection, they usually rely on automated detection equipment. These devices can improve the detection speed and accuracy to a certain extent, but they also have some limitations. Specifically, when the production line transports the battery to the designated position, it needs to stop temporarily so that the automated detection equipment can complete the detection process. Although this pause is not long, in the context of large-scale and continuous production, it is sufficient to affect the overall production efficiency. In addition, frequent starts and stops not only increase the risk of mechanical wear but also may lead to instability of the production rhythm, thereby further reducing the efficiency of the production line. Summary of the Invention

It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0031] Embodiment: A lithium battery assembly detection device, see Figures 1-9 As shown, it includes a support frame 1, a detector 2 and a conveyor 3; the detector 2 is installed in the middle of the front upper side of the support frame 1; the conveyor 3 is arranged on the upper side of the support frame 1;

[0032] It further includes a connecting block 4, a first motor 5, a support seat 6, a conductive tube 7, a conductive block 8, an electrode plate 9, a conductive rod 10, a reset mechanism, an orientation detection mechanism, a connecting frame 13, an electrode guide rail 14 and a pressing mechanism; Connecting blocks 4 are evenly spaced and installed on the outer side of the conveyor belt of the conveyor 3; A first motor 5 is installed in the middle of the connecting block 4; A support seat 6 is connected to the output shaft of the first motor 5; Conductive tubes 7 are symmetrically and slidably arranged front and back on the support seat 6. The surfaces of the two conductive tubes 7 on the support seat 6 facing each other are set as arc surfaces. The inner diameter of the conductive tube 7 is smaller than the outer diameter of the battery. The conductive tube 7 is used to clamp and fix the battery, and the conductive tube 7 is made of a conductive material; Conductive blocks 8 are symmetrically arranged front and back inside the support seat 6. The conductive block 8 is made of a conductive material. The conductive blocks 8 on the front and back sides are respectively in contact with the conductive tubes 7 on the front and back sides; Electrode plates 9 are symmetrically arranged front and back on the top of the connecting block 4. The electrode plate 9 is made of a conductive material. The electrode plates 9 on the front and back sides are respectively in contact with the conductive blocks 8 on the front and back sides; A conductive rod 10 is slidably arranged on the electrode plate 9. The conductive rod 10 is made of a conductive material; A reset mechanism is arranged on the support seat 6. The reset mechanism is used to reset the conductive tube 7 and the conductive rod 10 after they move; An orientation detection mechanism is arranged on the support frame 1. The orientation detection mechanism is used to detect the orientation of the battery. When the positive and negative poles of the battery face in the opposite direction, the support seat 6 is driven by the first motor 5 to rotate 180 degrees to adjust the positive and negative pole orientation of the battery; Connecting frames 13 are symmetrically arranged front and back on the upper side of the support frame 1; Six electrode guide rails 14 are spaced at the bottom inside the connecting frame 13. The six electrode guide rails 14 on the front side are electrically connected to the positive electrode in the detector 2, and the six electrode guide rails 14 on the back side are electrically connected to the negative electrode in the detector 2. The connecting blocks 4 on the conveyor belt of the conveyor 3 are grouped into groups of six adjacent ones. When the six connecting blocks 4 in the same group are in a horizontal state and when these six connecting blocks 4 are located above the conveyor 3, the lengths of the electrode plates 9 on these six connecting blocks 4 decrease sequentially from right to left. Moreover, the distance between the two conductive rods 10 on the connecting blocks 4 in the same group also decreases sequentially from right to left. Among them, the two conductive rods 10 on the rightmost connecting block 4 in the same group are aligned with the two outermost electrode guide rails 14. Similarly, the two conductive rods 10 on other connecting blocks 4 in the same group are aligned with the other two electrode guide rails 14 at other positions;Moreover, the left side surface of the leftmost connecting block 4 in the same group is flush with the left side surface of the electrode guide rail 14, and the right side surface of the rightmost connecting block 4 in the same group is flush with the right side surface of the electrode guide rail 14, so that the distance between the left and right sides of the electrode guide rail 14 is the same as the distance between the leftmost and rightmost of the six connecting blocks 4 in the same group. In this way, the electrode guide rail 14 can only be in contact with one conductive rod 10 each time, thus preventing the electrode guide rail 14 from coming into contact with two conductive rods 10 simultaneously. By connecting the front conductive rod 10 into the front electrode guide rail 14 and simultaneously connecting the rear conductive rod 10 into the rear electrode guide rail 14, a circuit can be formed among the battery, the conductive tube 7, the conductive block 8, the electrode plate 9, the conductive rod 10, the electrode guide rail 14, and the detector 2, enabling the detector 2 to detect the voltage and internal resistance of the battery. A pressing mechanism is provided on the connecting frame 13, and the pressing mechanism is used to press the conductive rod 10 so that the conductive rod 10 is in close contact with the electrode guide rail 14;

[0033] See Figure 5 and Figure 6 As shown, the reset mechanism includes a first spring 1101 and a second spring 1102; a first spring 1101 is connected between the conductive tube 7 and the support base 6, and the first spring 1101 is used for resetting after the conductive tube 7 moves; a second spring 1102 is connected between the upper side of the conductive rod 10 and the top of the electrode plate 9, and the second spring 1102 is used for resetting after the conductive rod 10 moves.

[0034] See Figure 6 and Figure 7 As shown, the orientation detection mechanism includes a sliding plate 1201, a third spring 1202, a laser receiver 1203, a touch switch 1204, a fixed frame 1205, and a laser emitter 1206; a sliding plate 1201 is slidably arranged inside the conductive tube 7; a third spring 1202 is connected between the sliding plate 1201 and the inner side of the conductive tube 7; a laser receiver 1203 is arranged on the conductive tube 7, and the laser receiver 1203 is slidably connected to the support base 6. A touch switch 1204 is arranged on the side of the laser receiver 1203 facing the sliding plate 1201, and the touch switch 1204 is electrically connected to the laser receiver 1203. The touch switch 1204 is located inside the conductive tube 7, and the sliding plate 1201 is used to contact the touch switch 1204; a fixed frame 1205 is installed at the rear part of the upper left side of the support frame 1; a laser emitter 1206 is arranged on the fixed frame 1205, and the laser emitter 1206 is used to emit laser light, while the laser receiver 1203 is used to receive the laser light. Both the laser receiver 1203 and the first motor 5 are electrically connected to the detector 2. When the laser receiver 1203 receives a signal, the laser receiver 1203 will send a signal to the detector 2, and the detector 2 will control the first motor 5 to drive the support base 6 to rotate.

[0035] See Figure 7 andFigure 9 As shown, the pressing mechanism includes a magnetic block 1501 and a magnetic plate 1502; a magnetic block 1501 is installed at the top of the conductive rod 10; six magnetic plates 1502 are installed at intervals on the inner top of the connection frame 13, and the magnetic plates 1502 and the magnetic block 1501 press the conductive rod 10 through repulsive force.

[0036] During use, the battery is successively clamped between two conductive tubes 7 on the upper left support base 6 through a feeding device. When the battery contacts the arc surface of the conductive tube 7, the battery will squeeze the two conductive tubes 7 on the support base 6 to move away from each other, and the first spring 1101 is compressed. By using the elastic force of the first spring 1101, the first spring 1101 can apply pressure to the conductive tube 7, so that the two conductive tubes 7 on the support base 6 clamp the battery, thereby fixing the battery and making the two conductive tubes 7 on the support base 6 contact the positive and negative electrodes of the battery respectively. At the same time, since the positive electrode surface of the battery has a convex structure and the negative electrode surface has a concave structure, when the battery contacts the conductive tube 7, the convex structure of the battery positive electrode will squeeze the sliding plate 1201 in the conductive tube 7 to move towards the side close to the touch switch 1204, and the third spring 1202 is compressed, so that the sliding plate 1201 presses the touch switch 1204, thereby enabling the touch switch 1204 to control the laser receiver 1203 connected thereto to turn on. As a result, the laser receiver 1203 facing the same direction as the battery positive electrode will be in an on state. Then, the conveyor 3 continuously conveys the connecting block 4 on the conveyor belt, so that the connecting block 4 moves along the set circular path following the conveyor belt. By using the laser emitted by the laser emitter 1206, when the connecting block 4 drives the first motor 5, the support base 6, the conductive tube 7 and the laser receiver 1203 thereon to move to align with the laser emitter 1206, if the positive electrode of the battery faces forward, the front laser receiver 1203 will be in an on state, and at this time, the front laser receiver 1203 cannot receive the laser emitted by the laser emitter 1206. Therefore, the orientation of the battery does not need to be adjusted. If the positive electrode of the battery faces backward, the rear laser receiver 1203 will be in an on state, and at this time, the rear laser receiver 1203 can receive the laser emitted by the laser emitter 1206. After the laser receiver 1203 receives the laser, the laser receiver 1203 will send a signal to the detector 2. After the detector 2 receives the signal, it controls the first motor 5 to drive the support base 6 to rotate 180 degrees, thereby driving the conductive tube 7, the conductive block 8 and the battery to rotate 180 degrees, so as to automatically adjust the orientation of the battery so that the positive electrode of the battery faces forward. Then, when the connecting block 4 drives the first motor 5, the support base 6, the conductive tube 7 and the laser receiver 1203 thereon to continue to move, the connecting block 4 will drive the electrode plate 9, the conductive rod 10 and the magnet 1501 into the connecting frame 13, so that the conductive rod 10 enters the corresponding electrode guide rail 14. And as the magnet 1501 enters the connecting frame 13, the magnetic plate 1502 at the top inside the connecting frame 13 will squeeze the magnet 1501 to move downward through the repulsive force, thereby driving the conductive rod 10 to move downward to closely contact the bottom inside the electrode guide rail 14, and the second spring 1102 is compressed, so that the conductive rod 10 contacts the bottom inside the electrode guide rail 14, thereby enabling the positive electrode of the battery to form a circuit with the detector 2 through the front conductive tube 7, the conductive block 8, the electrode plate 9, the conductive rod 10 and the electrode guide rail 14.And make the negative electrode of the battery form a path with the detector 2 through the conductive tube 7, conductive block 8, electrode plate 9, conductive rod 10 and electrode guide rail 14 at the rear side. In this way, the detector 2 can be electrically connected to the battery. Then, the detector 2 can be used to detect the voltage and internal resistance of the battery until the detector 2 completes the detection of the voltage and internal resistance of the battery. After that, when the connecting block 4 drives the first motor 5, support seat 6, conductive tube 7 and laser receiver 1203 thereon to continue moving, the connecting block 4 will drive the electrode plate 9, conductive rod 10 and magnetic block 1501 to leave the connecting frame 13, and the conductive rod 10 will leave the corresponding electrode guide rail 14, so that both the positive and negative electrodes of the battery are disconnected from the detector 2. And as the magnetic block 1501 leaves the connecting frame 13, the force exerted by the magnetic plate 1502 to squeeze the magnetic block 1501 downward by the repulsive force will gradually decrease. When the force exerted by the magnetic plate 1502 to squeeze the magnetic block 1501 downward is less than the elastic force of the second spring 1102, the second spring 1102 returns to its original state, and the second spring 1102 drives the conductive rod 10 and the magnetic block 1501 to move upward and reset. Then, the discharging device can be used to remove the battery that has completed the detection from the support seat 6, so that the battery that has completed the detection is separated from the two conductive tubes 7 on the support seat 6. When the battery that has completed the detection is separated from the two conductive tubes 7 on the support seat 6, the first spring 1101 returns to its original state, and the first spring 1101 drives the two conductive tubes 7 on the support seat 6 to move toward each other and reset. When the battery is separated from the conductive tube 7, the convex structure at the positive electrode of the battery will be separated from the sliding plate 1201 in the conductive tube 7. At this time, the third spring 1202 returns to its original state, and the third spring 1202 drives the sliding plate 1201 to move away from the touch switch 1204 and reset, so that the sliding plate 1201 releases the touch switch 1204, thereby causing the touch switch 1204 to control the laser receiver 1203 connected thereto to turn off. After that, by repeating the above operations, the voltage and internal resistance of the battery can be repeatedly detected. By cooperating with the laser emitter 1206 and the laser receiver 1203, the orientation of the battery during transportation can be automatically adjusted, and through the long-term contact between the conductive rod 10 and the electrode guide rail 14, the battery can also be detected while the battery continues to be transported, thereby preventing pauses during the detection and improving the overall production efficiency to ensure the stability of the production rhythm.

[0037] See Figure 4 As shown, it further includes a support block 16; support blocks 16 are symmetrically installed on the front and rear sides of the lower side of the support seat 6, and the support blocks 16 are used to support the battery.

[0038] By providing the support block 16, the battery clamped by the conductive tube 7 can be supported by the support block 16 to improve the stability of the battery.

[0039] See Figure 10 and Figure 11As shown, it further includes a feeding mechanism, which includes a connecting frame 17, a feeding frame 18, a hollow cylinder 19, a second motor 20 and a turntable 21; a connecting frame 17 is installed on the lower left side of the support frame 1; a feeding frame 18 is arranged at the top of the connecting frame 17, and the inner bottom surface of the feeding frame 18 is an inclined surface that is higher on the left and lower on the right. The feeding frame 18 is used for feeding the batteries; the right side of the bottom of the feeding frame 18 communicates with a hollow cylinder 19; a second motor 20 is installed in the middle of the front side of the hollow cylinder 19; two turntables 21 are arranged on the output shaft of the second motor 20, and both turntables 21 are located inside the hollow cylinder 19, and the two turntables 21 are distributed front and back; concave grooves 22 are arranged at intervals on the turntable 21, and the concave grooves 22 are used for placing the batteries.

[0040] See Figure 11 and Figure 12 As shown, it further includes an adsorption mechanism, which includes a magnet 23 and a limiting plate 24; magnets 23 are arranged at intervals on the turntable 21, and the magnets 23 are located in the concave grooves 22. The magnets 23 are used for adsorbing the batteries; a limiting plate 24 is arranged at the lower right side inside the hollow cylinder 19, and the limiting plate 24 is located between the two turntables 21. The limiting plate 24 is used for limiting the batteries.

[0041] By setting the feeding mechanism and the adsorption mechanism, when it is necessary to sequentially clamp the batteries between the two conductive tubes 7 on the upper left support seat 6 through the feeding device, an appropriate amount of batteries can be put into the feeding frame 18 in advance, so that the batteries roll to the right along the inclined surface at the bottom of the feeding frame 18 and fall into the hollow cylinder 19. Then, the second motor 20 drives the turntable 21 to rotate counterclockwise. When the concave groove 22 on the turntable 21 is aligned with the battery falling into the hollow cylinder 19, the battery will be clamped into the concave groove 22 and contact the magnet 23, so that the magnet 23 in the concave groove 22 will suck the battery to fix the battery. Then, as the turntable 21 rotates counterclockwise, the turntable 21 will drive the battery in the concave groove 22 to rotate counterclockwise together. When the battery contacts the arc surface on the conductive tube 7, the battery will squeeze the two conductive tubes 7 on the support seat 6 to move away from each other. Then, by applying pressure to the conductive tube 7 with the first spring 1101, the two conductive tubes 7 on the support seat 6 can clamp the battery to fix it. Then, the conveyor 3 conveys the connecting blocks 4 on the conveyor belt, and the connecting blocks 4 can drive the support seat 6, the conductive tube 7 and the battery on it to move. At the same time, as the turntable 21 continues to rotate counterclockwise, the limiting plate 24 can limit the battery between the two conductive tubes 7, so that the battery gradually disengages from the concave groove 22 and gradually separates from the magnet 23. Then, the turntable 21 repeats bringing the batteries in the hollow cylinder 19 between the two conductive tubes 7 on the support seat 6. In this way, automatic feeding of the batteries can be realized.

[0042] See Figure 10 and Figure 13As shown in the figure, it further includes a blanking mechanism, which includes a discharge frame 25, an electric push rod 26 and a U-shaped rod 27; the discharge frame 25 is installed at intervals on the lower side of the support frame 1, and the discharge frame 25 is used for discharging the battery; an electric push rod 26 is arranged at the bottom inside the discharge frame 25, and the electric push rod 26 is electrically connected to the detector 2; a U-shaped rod 27 is connected to the telescopic rod of the electric push rod 26.

[0043] By setting the blanking mechanism, after the detector 2 completes the detection of the voltage and internal resistance of the battery, the detector 2 can be used to signal-mark the battery according to the detection conditions of the voltage and internal resistance; when it is necessary to use the unloading device to remove the detected battery from the support seat 6, it can be waited for the connecting block 4 to drive the first motor 5, the support seat 6, the conductive tube 7 and the laser receiver 1203 thereon to move, so that the battery clamped by the conductive tube 7 moves synchronously. When the signal-marked battery is directly above the corresponding electric push rod 26, the detector 2 will control the corresponding electric push rod 26 to drive the U-shaped rod 27 to rise, so that the battery clamped by the conductive tube 7 is inside the U-shaped rod 27. Then, as the connecting block 4 drives the first motor 5, the support seat 6, the conductive tube 7 and the laser receiver 1203 thereon to continue to move, the U-shaped rod 27 can block the movement of the battery clamped by the conductive tube 7, so that the conductive tube 7 is gradually separated from the clamped battery. When the conductive tube 7 is separated from the battery, the battery will fall down due to gravity into the corresponding discharge frame 25 for discharging. At the same time, the detector 2 will control the corresponding electric push rod 26 to drive the U-shaped rod 27 to descend and reset. In this way, it is possible to automatically blank the detected battery and automatically classify the detected battery according to the detection conditions of the voltage and internal resistance.
