Description

Technical Field

[0001] The utility model relates to the field of lithium cobalt oxide battery testing, in particular to a lithium cobalt oxide testing and screening machine. Background Art

[0002] Lithium cobalt oxide batteries have a stable structure, high capacity ratio, and outstanding comprehensive performance, but their safety is poor and their cost is very high. They are mainly used in small and medium-sized cells and are widely used in small electronic devices such as laptops, mobile phones, MP3 / 4, etc. Lithium cobalt oxide batteries need to be tested after production in order to sort out unqualified lithium cobalt oxide batteries.

[0003] According to a Chinese patent with publication number CN220804468U, a lithium battery production test tool is disclosed. By setting a positioning clamping mechanism, not only can the clamping motor be used to drive the two clamping arms to move relative to each other, so as to clamp and fix lithium batteries of different sizes and shapes, but also the test translation motor can be used to realize the relative movement of the two lifting test devices, so that the battery connection terminal can be connected to the positive and negative poles of the lithium battery.

[0004] In view of the above-mentioned disclosed patent content, a placement seat and a placement slot are provided so that the lithium cobalt oxide battery can be placed in the placement slot for transportation. However, the placement slot is exposed to the external environment for a long time, and a large amount of dust may accumulate and adhere to the placement slot. In order to ensure that the lithium cobalt oxide battery is placed stably and avoid one end of the lithium cobalt oxide battery from tilting up due to dust accumulation, the placement slot needs to be cleaned at regular intervals to ensure that the placement slot is clean so that the lithium cobalt oxide battery can be placed stably.

[0027] 1. The utility model is provided with a cleaning component. When a lithium cobalt oxide battery in a placement seat is tested, there will be a placement seat corresponding to the cleaning block. When the first threaded seat and the movable seat move downward, they will drive the first rack to move downward, and then drive the gear to rotate. The gear drives the second rack to move inside the body, and drives the connecting rod and the cleaning block to move, so that the cleaning block moves into the placement groove to clean the placement groove, so as to prevent impurities from remaining inside the placement groove, which makes it difficult to place the lithium cobalt oxide battery flat in the placement groove, and facilitate the subsequent testing of the lithium cobalt oxide battery. When the first threaded seat and the movable seat move upward and reset, they will drive the first rack to reset and move, and drive the second rack and the cleaning block to move, so that the cleaning block moves out of the placement groove to avoid affecting the conveyor belt to transport the placement seat;

[0028] 2. The utility model is provided with a clamping assembly. When the lifting frame moves downward, it will drive the fixed cylinder to move downward, and then drive the pressure rod and the pressure plate to move downward, so that the pressure plate contacts the top of the lithium cobalt oxide battery. As the lifting frame continues to move downward, the pressure plate does not move and the movable block squeezes the spring, so that the spring is compressed. At this time, the pressure plate will tightly press the lithium cobalt oxide battery under the reaction force of the spring, thereby improving the stability of the lithium cobalt oxide battery. In this way, there is no need to add an additional electric drive structure to drive the pressure plate to move, so as to achieve the purpose of limiting the lithium cobalt oxide battery, thereby reducing the energy consumption of the machine. At the same time, due to the setting of the spring, it can be avoided that the pressure plate will not apply a large squeezing force to the lithium cobalt oxide battery when it contacts the lithium cobalt oxide battery for the first time, thereby preventing damage to the lithium cobalt oxide battery, thereby improving the protection effect on the lithium cobalt oxide battery.

[0044] Embodiment 2:

[0045] On the basis of the above-mentioned embodiment 1, in order to improve the stability of the lithium cobalt oxide battery and prevent it from moving randomly during the detection process, the lithium cobalt oxide battery needs to be compressed and limited, so the following structure is set.

[0047] The working principle of the utility model is as follows: first, the staff can install the screening machine and turn on the power supply, then put the lithium cobalt oxide battery to be tested into the placement slot 5 on the placement seat 4, and then transmit it through the conveyor belt 2. When the lithium cobalt oxide battery enters the fixing frame 6 and moves to the bottom of the lifting frame 14, the conveyor belt 2 is shut down, and then the first motor 11 is started. The first motor 11 can drive the threaded column 13 to move downward, and drive the first threaded seat 12 to move downward, and drive the lifting frame 14 to move downward, and drive the detection plate 18 and the fixed cylinder 801 to move downward.

As the lifting frame 14 continues to move downward, The pressing plate 805 does not move, while the movable block 803 squeezes the spring 802, so that the spring 802 is compressed. At this time, the pressing plate 805 is subjected to the reaction force of the spring 802 and will press the lithium cobalt oxide battery tightly. When the battery connection terminal 20 on the detection plate 18 corresponds to the positive and negative poles of the lithium cobalt oxide battery, the first motor 11 is turned off and the second motor 15 is started.

[0049] When the detection of the lithium cobalt oxide battery is completed, the bidirectional screw rod 17 is first reversed by the second motor 15, and then the detection plate 18 is driven to reset and move, and the first motor 11 is started to make the lifting frame 14 move up and reset. When the first threaded seat 12 and the movable seat 26 move up and reset, they will drive the first rack 901 to reset and move, and drive the second rack 905 and the cleaning block 909 to move, so that the cleaning block 909 is moved out from the placement groove 5, and then the conveyor belt 2 continues to drive the lithium cobalt oxide battery to move. If the detection is unqualified, the cylinder 22 can be started to move the push block 23, and the push block 23 can push the lithium cobalt oxide battery into the drop port 24, and then fall into the collection box 25 through the drop port 24, so that the lithium cobalt oxide batteries that pass and fail the detection can be screened.
