Description

Technical Field

[0002] Compared with ordinary lead-acid batteries, lithium batteries have the characteristics of high energy conversion, higher voltage and capacity, which has led to an increasing number of products using lithium batteries on the market, and the safety issues of lithium batteries have become increasingly important.

[0003] There are many testing procedures in the production process of lithium batteries. For example, the common formation test and capacity test are to charge the internal parts of the battery to eliminate the inferior batteries. The quality of the battery cell can directly determine whether the battery is inferior. Since most application scenarios of lithium batteries have high power requirements, the charging and discharging power safety of the battery cell is often the focus of the staff during this test.

[0004] In the current lithium battery testing process, due to the large number and variety of batteries themselves, people often have to group and match them for unified testing. The sorting devices are mostly manually operated, and they are inevitably mixed due to different types. In addition, the battery cells may also be reverse charged due to problems or improper operation during the test charge and discharge process, which not only affects the production efficiency, but also poses many safety hazards to operators. Therefore, when power mismatched problem parts are detected during charge and discharge, the problem parts are moved out of the test area to prevent them from continuing to discharge and causing hidden dangers. Therefore, a lifting and caching device for different battery cell classifications is needed. Summary of the invention

[0019] The present invention is further described below in conjunction with the accompanying drawings.

[0020] Refer to the attached figure:

[0021] Embodiment 1 The present invention discloses a lifting and caching device for classifying different battery cells, comprising a support unit 1 and a lifting unit 2 arranged on the support unit, wherein the support unit 1 comprises a base 11 and four sets of lifting cylinders 12, wherein the lifting cylinders 12 are vertically suspended at the bottom of the base 11, and each vertical lifting end of the lifting cylinders 12 is equipped with a set of lifting units 2 for driving the lifting units 2 to lift vertically; the lifting unit 2 is used to lift and move the battery into the battery detection area, and can also reach the position of the lifting mechanism during the lifting process to move the battery into the lifting mechanism, comprising a lifting platform 21, a clamping block 22 and a detection device 23, wherein the lifting platform 21 is horizontally located directly above the base 11, and the bottom of the lifting platform 21 is connected to the corresponding vertical lifting end of the lifting cylinder 12; the two clamping blocks 22 are detachably mounted at the opposite ends of the lifting platform 21 for clamping on the opposite sides of the battery 3; the detection device 23 is arranged between the two clamping blocks for detecting whether a battery is clamped between the two clamping blocks.

[0022] The base 11 can be installed between the conveyor line and the lifting mechanism, and includes a support frame 111 and a support plate 112. The support frame 111 has two opposite frames. The opposite inner sides of the frames are provided with a slot for engaging with the end of the support plate 112 along the axial direction of the frame, and a positioning block 113 is respectively provided at both ends of the slot, which is used to limit the support plate in the slot between the two positioning blocks. The spacing between the support plates 112 can be adjusted by adjusting the position of the positioning block. Batteries with different power levels can be tested and classified separately when the spacing is adjusted to a sufficient distance without interfering with each other; a through hole is provided in the middle of the support plate 112 for the vertical lifting end of the lifting cylinder 12 to pass through. The lifting cylinder 12 is vertically suspended at the bottom of the support plate 112, and the vertical lifting end of the lifting cylinder 12 is connected to the bottom of the lifting unit 2 after passing through the through hole, and the corresponding lifting unit 2 is controlled to be lifted and lowered respectively, which is convenient for testing and also convenient for placing batteries of different categories at different heights for distinction after classification. Batteries with different powers mean that their internal resistances are different. When the batteries are mixed, the operator cannot determine their accurate power range. Therefore, the lifting units 2 need to be grouped for separate detection. To prevent interference, a safe distance must be maintained between the battery cells.

[0023] A linear bearing 114 is embedded in each end of the support plate 112, and a lifting rod 115 is inserted in each linear bearing 114. The top of the lifting rod 115 is connected to the bottom of the lifting unit 2 located above the support plate 112. The lifting rod 115 cooperates with the lifting cylinder 12 to lift, and its height can be adjusted according to the floor height of other transportation and lifting mechanisms in actual applications. The lifting cylinder 12 and the lifting rod 115 are connected to the sensing device in the battery test area. During the test, one or more groups of problem parts are promptly removed to the corresponding height through group isolation to ensure the safety of the test work. The lifting rod 115 and the lifting cylinder 12 are the power sources of the lifting unit 2. Through this simple mechanism, not only is the cost saved, making the equipment convenient for more small and medium-sized enterprises to use, but also the problem of slow classification and recycling after the test is completed, which affects the production efficiency, is solved.

The connecting base plate 211 and the distance-adjusting plate 212 are both rectangular plates arranged along the axial direction of the support plate.

By adjusting the installation positions of the two clamping blocks 22 on the distance-adjusting plate 212 and adjusting the distance between the two clamping blocks 22, the height of the clamping blocks 22 can be adjusted to increase the sensing range of the sensing element 231, thereby adapting to different types of batteries.

[0025] The material of the clamp block 22 is mainly POM, which is an indispensable component in battery loading. It not only insulates and prevents leakage of the battery cell to form protection, but also facilitates replacement and change of its shape to adapt to battery cells of different specifications. By adjusting its opening (such as a U-shaped opening for loading square batteries), various battery cells of different shapes can be loaded; specifically, the clamp block 22 is a U-shaped block, including an opening and a connecting bottom opposite to the opening, and the openings of the two clamp blocks are kept facing each other; the connecting bottom of the clamp block is provided with a vertical waist-shaped hole 221, which can not hinder the vertical height adjustment of the detection device.

[0026] The detection device 23 includes a sensing element 231 and a detection sensor assembly 232. The sensing element 231 is arranged between the two clamps 22, and the two signal output ends of the sensing element 231 pass through the waist-shaped hole 221 of the clamp 22 on the same side and are electrically connected to the signal input end of the detection sensor assembly 231. The sensing element 231 senses within the range of the lifting platform 21 and transmits the battery signal to the sensor to avoid human misoperation. At the same time, the sensing height of the sensor can be adjusted with the clamp. Specifically, the sensing element is a battery sensing device. If the battery in the sensing area is not loaded or loaded irregularly, an alarm is used to remind the staff who are about to perform the next operation to adjust the battery position first. The detection sensor assembly 231 includes a sensor fixing frame 232 and a detection sensor 233, wherein the sensor fixing frame 232 is an inverted L-shaped fixing block having a vertical connection portion and a horizontal mounting portion, wherein the vertical connection portion is provided with a vertical waist hole 234, and the sensor fixing frame 232 is detachably mounted on the connecting base plate 211 by fastening screws, and is located on the outer wall side of the clamping block 22; the detection sensor 233 is fixedly mounted on the horizontal mounting portion, and the signal input end of the detection sensor 233 is electrically connected to the signal output end of the sensing element on the same side.
