Description

Technical Field

[0001] This utility model relates to the field of lithium battery testing technology, and in particular to an automatic batch testing device for lithium batteries. Background Technology

[0002] To ensure the quality of lithium batteries meets standards, voltage testing is required after processing. Existing patent (publication number: CN219737716U) discloses a lithium battery testing device. This device uses a lithium battery box and a transport mechanism. When the transport mechanism starts operating, it transports the lithium batteries to the electrode plates for testing, thus achieving automatic voltage detection and improving the automation level of the device. However, in practical applications, after the lithium batteries slide down the inclined surface of the base, they are placed sequentially on the support portion of the transport mechanism. Different models of lithium batteries have different radii. On the one hand, the arc-shaped support portion is difficult to stably support lithium batteries of different sizes. Lithium batteries with too small a radius are prone to shaking when placed in a support portion with a relatively large radius, resulting in unstable installation. On the other hand, the lithium battery box cannot maintain a state of outputting batteries one by one during operation, hindering normal testing. Therefore, we propose a batch automatic testing device for lithium batteries. Utility Model Content

[0003] To address the aforementioned problems, this invention provides an automated batch testing device for lithium batteries.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] Design an automated batch testing device for lithium batteries, including a frame with an internal conveying mechanism, a V-shaped support frame that moves with the conveying mechanism, a detection mechanism at one end of the frame, the detection mechanism including multiple clamping plates at both ends of the V-shaped support frame, electrode plates on the inner wall of the clamping plates, a discharge box connected to the top of the other end of the frame, a funnel-shaped guide container below the discharge box, and adjusting components movably inserted on both sides of the guide container, the adjusting components including guide rollers parallel to the length direction of the V-shaped support frame.

[0006] In the above scheme, the detection mechanism includes a pair of detection arms mounted on the frame, a drive shaft connected to the motor is movably mounted between the detection arms, and the clamping plate is fixed to the drive shaft.

[0007] In the above scheme, the discharge box is provided with a pull-out opening near the bottom, and a discharge plate is slidably connected inside the pull-out opening.

[0008] In the above scheme, positioning plates are fixed on both sides of the discharge box, and positioning slots that cooperate with the positioning plates are fixed on the top of the frame.

[0009] In the above scheme, the flow guiding container includes a flow guiding channel and a flow dividing channel connected vertically, the adjustment component also includes a bracket that movably passes through the flow dividing channel, the flow guiding roller is installed in the bracket, and the frame is threaded with an adjustment screw that is movably connected to the bracket.

[0010] In the above scheme, recycling bins are provided at the bottom of both sides of the frame.

[0011] In the above scheme, the end of the conveying mechanism is provided with a receiving box, and an inclined guide is connected between the end of the frame and the top of the receiving box.

[0012] The advantages and beneficial effects of this utility model are as follows: By setting up a discharge box, frame, guide trough, and diversion trough, the neatly arranged cylindrical batteries fall downwards into the guide trough through the discharge box. Utilizing the gradually decreasing width of the guide trough, the parallel arrangement of multiple batteries is transformed into a single battery per row. Compared with existing technologies, this avoids multiple batteries falling onto the conveying mechanism simultaneously, ensuring stable battery diversion and discharge, and effectively controlling the battery discharge speed to coordinate with the operating speed of the conveying mechanism. By setting up a conveying mechanism and a V-shaped support frame, the conveying mechanism is modified using the V-shaped support frame, which in turn supports the batteries falling from the diversion trough. The shape of the V-shaped support frame allows for stable loading of batteries of different radii. Compared with existing technologies, this effectively prevents batteries of different sizes from swaying on the conveying mechanism, improving the stability of battery transfer and making it suitable for batteries of various radii, thus making it more convenient to use.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] Please see Figure 1-2 This utility model provides a technical solution: a batch automatic testing device for lithium batteries, including a frame 1 with an internal conveying mechanism 2, a power device for driving the conveying mechanism 2 installed on the frame 1, a V-shaped support frame 3 that moves with the conveying mechanism 2, the conveying mechanism 2 is a chain-type conveying mechanism, and the V-shaped support frame 3 is detachably connected to the corresponding chain plate, so that the conveying mechanism 2 is more conducive to stable battery conveying.

[0019] Specifically, by setting up a conveying mechanism 2 and a V-shaped support frame 3, the conveying mechanism 2 is modified using the V-shaped support frame 3. Together with the V-shaped support frame 3, the batteries falling from the diversion channel 11 are supported. Combined with the shape of the V-shaped support frame 3, batteries of different radii can be stably loaded. Compared with the existing technology, it can effectively prevent batteries of different sizes from shaking on the conveying mechanism 2. It can not only improve the stability of battery transfer, but also be applicable to batteries of various different radii, making it more convenient to use.

[0020] The frame 1 is equipped with a detection mechanism at one end. The detection mechanism includes multiple clamping plates 17 located at both ends of the V-shaped support frame 3. Electrode plates 18 are provided on the inner wall of the clamping plates 17.

[0021] Furthermore, the detection mechanism includes a pair of detection arms 15 mounted on the frame 1. Photoelectric sensors are mounted on the detection arms 15. A drive shaft 16 connected to the motor 19 is movably mounted between the detection arms 15. Pulleys are mounted on both the output shaft of the motor 19 and the drive shaft 16. The pulleys are connected by a belt. The clamping plate 17 is fixed to the drive shaft 16.

[0022] Specifically, when the photoelectric sensor detects the passing of the battery, the motor 19 is started, which in turn drives the drive shaft 16 to rotate, causing the clamping plate 17 to rotate, which in turn causes the electrode plate 18 to attach to both ends of the battery, connecting the electrode plate 18 to the battery, thereby detecting the battery voltage.

[0023] The top of the other end of the frame 1 is connected to a discharge box 4;

[0024] Furthermore, the discharge box 4 is provided with a pull-out port 5 near the bottom, and a discharge plate 6 is slidably connected inside the pull-out port 5; the produced batteries are neatly placed in the discharge box 4, then the discharge box 4 is placed on the top of the frame 1, and then the discharge plate 6 is pulled out, so that the batteries in the discharge box 4 fall downwards.

[0025] Furthermore, positioning plates 7 are fixed on both sides of the discharge box 4, and positioning slots 8 that cooperate with the positioning plates 7 are fixed on the top of the frame 1; by holding the handles at both ends of the discharge box 4, the discharge box 4 is lifted upwards, and the positioning plates 7 and positioning slots 8 are used to quickly position the two, so as to avoid misalignment between the discharge box 4 and the frame 1.

[0026] Below the discharge box 4 is a funnel-shaped guide container, and adjustment components are movably inserted on both sides of the guide container. The adjustment components include guide rollers 13 that are parallel to the length direction of the V-shaped support frame 3.

[0027] Furthermore, the flow guide container includes a flow guide trough 10 and a flow divider 11 connected vertically. The adjustment assembly also includes a support 12 that movably passes through the flow divider 11. The flow divider 12 has movable openings on both sides that cooperate with the support 12. The flow guide roller 13 is horizontally and movably installed inside the support 12. The frame 1 is threadedly fitted with an adjustment screw 14 that is movably connected to the support 12. The end of the adjustment screw 14 is assembled with the support 12 through a movable seat. The frame 1 has a screw hole that cooperates with the adjustment screw 14. The inner wall of the frame 1 is fixed with a threaded guide cylinder that fits with the adjustment screw 14. The threaded guide cylinder provides support to the adjustment screw 14. By rotating the adjustment screw 14, the adjustment screw 14 moves in and out of the frame 1, thereby driving the support 12 and the flow guide roller 13 to move in and out of the flow divider 11, thereby adjusting the actual distance between the inner walls on both sides of the flow divider 11, thereby controlling the battery feeding speed, so that the batteries fall one by one, so as to cooperate with the V-shaped support frame 3.

[0028] Specifically, by setting up a discharge box 4, a frame 1, a guide trough 10, and a diversion trough 11, the neatly arranged cylindrical batteries fall downwards into the guide trough 10 through the discharge box 4. Utilizing the gradually decreasing width of the guide trough 10, the state of multiple batteries arranged side by side is transformed into a single battery per row. Compared with the prior art, this avoids multiple batteries falling onto the conveying mechanism 2 at the same time, allowing for stable diversion and discharge of batteries, and effectively controlling the battery discharge speed to coordinate with the operating speed of the conveying mechanism 2.

[0029] Furthermore, recycling bins 9 are provided on both sides of the bottom of the rack 1; these are used to collect batteries that have accidentally fallen out, so that they can be collected for retesting.

[0030] Furthermore, the end of the conveying mechanism 2 is provided with a receiving box 20, and an inclined guide 21 is connected between the end of the frame 1 and the top of the receiving box 20; the guide 21 is sloped so that the battery falls down along the surface of the guide 21 into the receiving box 20.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
