Problems solved by technology

This solution can ensure that the voltage and current lines can fully contact the tabs, but there are hidden dangers, because the thickness of the battery tabs is less than 0.1mm, and the gap between the upper platen and the conductive layer of the lower platen of the tab clamping device is too small when clamping , due to the problem of process accuracy, it is impossible to ensure that the upper platen and the lower platen are parallel, so it is easy to produce a short circuit and affect the accuracy of battery data collection. The contact surface between the pressure plate and the tab is a conductive layer, and the conductive layer circuit is divided into two parts, one part is connected to the voltage detection unit of the charging device, and the other part is connected to the current input and output lines. When the upper pressure plate and the lower pressure plate are closed by force, the battery tab Just contact with the conductive layer voltage line and current line at the same time

Example Embodiment

[0012] Example 1

[0013] according to figure 1 , figure 2 , image 3 , Figure 4 As shown, the present invention is based on the upper pressing plate 1, the lower pressing plate 2, the voltage conductive layer 3, and the current conductive layer 4. The characteristic is that the voltage conductive layer 3 and the current conductive layer 4 are respectively divided into ten conductive strips , And are arranged at even intervals to form conductive areas, and then connect the formed conductive layers through respective conductive buses; the conductive areas of the voltage conductive layer 3 and the conductive areas of the current conductive layer 4 alternately correspond to each other through the respective conductive strips. The engagement forms the tab clamping area, so that the tabs 5 in the tab clamping area when the lithium battery 6 is formed can also be in contact with the voltage conducting layer 3 and the current conducting layer 4 at the same time. The conductive strips...

Example Embodiment

[0014] Example 2

[0015] It is basically the same as Embodiment 1, and the difference is that the conductive strips of the voltage conductive layer 3 and the current conductive layer 4 are arranged horizontally, and the conductive strips are connected to the conductive bus obliquely.

[0016] The technical scheme of the present invention records that the conductive surface of the tab clamping device is divided into two groups, a group of current lines and a group of voltage lines, and then the two groups of lines are divided and thinned into a conductive line, and then the vertical vertical, vertical tilt, Horizontally vertical and horizontally inclined four ways are arranged alternately to clamp the conductive area. This design ensures that when the upper and lower pressing plates of the tab clamping device are closed, only the tab of the battery is required to produce more than one in the clamping area At the same time, the area of ​​the local contact area is larger than the gap...

Abstract

The invention relates to an electrode tab clamping device for battery formation and charging and discharging of lithium battery formation. According to the electrode tab clamping device, a voltage conducting layer and a current conducting layer are each formed through the steps that no less than one divided conducting strip are arranged at even intervals to form a conducting area, and then the conducting area is communicated through a corresponding conducting bus to form the conducting layer; the conducting area of the voltage conducting layer is in gap meshing with the conducting area of the current conducting layer through the corresponding conducting strips to form an electrode tab clamping area. The electrode tab clamping device for battery formation has the advantages that the structure is reasonable, manufacturing is convenient, and the electrode tab clamping device can adapt to formation of various types of lithium batteries; meanwhile, the phenomena that short circuit of a voltage line and a current line occurs, and the electrode tab voltage sampling precision is influenced by charging and discharging currents cannot occur during work; in addition, the phenomenon that the electrode tab clamping device is in bad contact due to the fact that an upper pressing plate and a lower pressing plate are unsmooth cannot occur, the service life is long, and the safety and reliability are achieved.

Description

technical field [0001] The invention relates to a tab clamping device for battery formation, in particular to a tab clamping device which forms a tab clamping area by arranging conductive strips at intervals. Background technique [0002] Lithium battery formation and capacity separation and other processes need to clamp the tabs to charge and discharge the battery. At present, the reliability of the existing tab clamping device is relatively poor, and the reliability of tab clamping during charging and discharging of a large number of batteries cannot be guaranteed. It is a conductive layer, the conductive layer of the upper pressing plate is connected to the voltage detection unit of the charging device, and the conductive layer of the lower pressing plate is connected to the current input and output lines, or the two are opposite. When the upper pressing plate and the lower pressing plate are closed by force, the conductive layer of the upper pressing plate and the con...
