Description
Technical Field
The invention relates to the technical field of batteries, in particular to a battery tab clamping device which is used for being in contact conduction with a battery tab to form electrical connection in the battery charging and discharging process.
Background
The battery tab clamping device is widely applied to battery processing and detection processes for charging and discharging batteries, and the battery tab is required to be clamped to charge and discharge the batteries in procedures such as lithium battery formation, capacity grading and the like; the charging and discharging usually adopt a four-wire method circuit, the acquisition and detection of a battery voltage signal are realized simultaneously in the charging and discharging process, and a voltage and current circuit is electrically connected with positive and negative battery tabs of a battery through a battery tab clamping device; set up the conducting circuit on the surface that battery utmost point ear clamping device and battery utmost point ear contacted, the circuit with battery utmost point ear after full contact, can make battery utmost point ear clamping device and battery utmost point ear switch on, conducting circuit divide into voltage line and electric current line, wherein: the voltage wire is communicated with a battery tab and is mainly responsible for collecting a voltage signal of the battery tab, and the current wire is communicated with the battery tab and can charge or discharge the battery; in the charging and discharging process, a current line and a voltage line are required to be in good contact with a battery tab, otherwise, the battery is abnormal in charging and discharging.
The battery tab clamping device in the prior art mainly adopts the following two design schemes:
in the first scheme, the contact surfaces of an upper pressing plate and a lower pressing plate of a battery tab clamping device 1 and a battery tab are set as conducting layers, the rest parts are an upper pressing plate insulating layer a1 and a lower pressing plate insulating layer b1, the circuit of the upper pressing plate conducting layer a2 is a voltage line and is connected with a voltage detection unit of a charging device, the circuit of the lower pressing plate conducting layer b2 is a current line and is connected with a current input and output circuit of the charging device, and the current input and output circuit is shown in fig. 1; the voltage and current lines are interchangeable; the upper pressure plate and the lower pressure plate are stressed to be closed, the upper pressure plate conducting layer a2 and the lower pressure plate conducting layer b2 are respectively contacted with the battery tab 6, and the charging device can realize voltage acquisition and battery charging and discharging. The scheme can effectively ensure that the voltage and current lines can fully contact the battery tabs, but hidden dangers also exist; the battery tab is very thin, the thickness of a plurality of battery tabs is less than 0.1, and the upper pressure plate conducting layer and the lower pressure plate conducting layer of the battery tab clamping device are not absolutely parallel; as shown in fig. 2, when the battery tab holding device 1 is forced to close, because the width of the battery tab holding device 1 is much greater than that of the battery tab 6, even if the battery tab 6 is separated from the middle of the battery tab holding device, the upper pressing plate conductive layer a2 and the lower pressing plate conductive layer b2 on the side of the battery tab holding device 1 far from the battery tab 6 are likely to contact with each other to cause short circuit, thereby affecting the reduction of the battery voltage collection precision and destroying the battery charging and discharging effect.
The second scheme is that the upper pressing plate of the battery tab clamping device is an upper pressing plate insulating layer a1 which is not conductive with the battery tab 6, the contact surface of the lower pressing plate and the battery tab is a conducting layer 4, the rest part of the contact surface is a lower pressing plate insulating layer b1, the circuit of the conducting layer 4 is divided into two parts of circuits, one part of the circuits is a voltage line L1 which is connected with a voltage detection unit of the charging device, and the other part of the circuits is a current line L2 which is connected with a current input and output circuit of the charging device, as shown in FIG. 3; the conducting layer can also be arranged on the upper pressing plate, and the voltage line and the current line can also be interchanged; when the upper pressing plate and the lower pressing plate are stressed to be closed, the battery tabs 6 are respectively in contact with the voltage line L1 and the current line L2 of the conducting layer 4 at the same time, and the charging device can realize voltage collection and battery charging and discharging. Although the scheme avoids the possible short circuit problem in the first scheme, the problem that the battery tab can be contacted with the voltage line and the current line of the conducting layer at the same time is more difficult to ensure; in order to enable the battery tab to be simultaneously contacted with a voltage line and a current line of a conducting layer, the whole surface of the upper pressing plate and the whole surface of the lower pressing plate of the device are required to be kept in good fitting degree, so that the design difficulty is improved; in the actual batch manufacturing process, the problem that the current line and the voltage line cannot be effectively contacted simultaneously due to poor fitting degree of the upper and lower pressing plates always occurs; as shown in fig. 4, whether the conductive layer 4 is placed on the upper platen or the lower platen, whether the voltage line L1 is closer to the battery or the current line L2 is closer to the battery, as long as the fit between the contact surfaces of the upper platen and the lower platen of the battery tab holding device 1 is not good, the battery tab 6 cannot contact both the voltage line L1 and the current line L2 of the conductive layer 4.
To sum up, in the traditional design, the reliability of battery tab clamping during the charge and discharge of mass batteries can not be guaranteed by the scheme one and the scheme two. In addition, the materials, hardness and thickness of various battery tabs are different, the contact surface between the battery tab clamping device and the battery tab can be uneven, and the battery tab clamping device and the battery tab can only be locally and tightly contacted when the battery tab is actually clamped; if the local area only belongs to the voltage line area, the battery voltage can only be measured and cannot be charged and discharged, and if the local area only belongs to the current line area, the real-time voltage of the battery in the charging and discharging process cannot be monitored, so that the battery is easily damaged due to overcharge or overdischarge. Therefore, a more reasonable battery tab clamping device needs to be designed to overcome the defects of the prior art and improve the reliability of battery tab clamping.

Example one
The technical scheme of the embodiment relates to a battery tab clamping device which comprises two pressing plate insulating layers, namely a first pressing plate insulating layer and a second pressing plate insulating layer, and further comprises a conducting layer arranged between the two pressing plate insulating layers, wherein the conducting layer is fixed on the second pressing plate insulating layer; the conducting layer includes two line concentration bodies and insulating interlayer, two line concentration bodies are the mass flow body of voltage line mass flow body and the current line mass flow body of connecting current input output circuit of connecting voltage detecting element respectively, wherein: the two line collecting bodies are separated by the insulating interlayer to realize insulation; the upper surface of one wire collecting body is a contact plane for contacting a battery tab; the other line concentration body is provided with a plurality of contact columns, the contact columns are elastic bodies protruding out of the contact plane, and the tops of the contact columns are flush with the contact plane and distributed on the contact plane at intervals in a compression state.
Specifically, as shown in fig. 5, in the present embodiment, the first pressing plate insulating layer 2 is an upper pressing plate, the second pressing plate insulating layer 3 is a lower pressing plate, and the conductive layer 4 is disposed between the two pressing plate insulating layers; the conductive layer 4 comprises a voltage line current collector 42, a current line current collector 41 and an insulating interlayer 43, a contact plane 411 is formed on the upper surface of the current line current collector 41, and a plurality of contact pillars 421 of the voltage line current collector 42 penetrate through the contact plane 411 to form a convex part; the current line current collector 41 and the voltage line current collector 42 are respectively and integrally conducted, and the current line current collector 41 and the voltage line current collector 42 are separated into two conductive parts which are not conducted with each other through the insulating interlayer 43; the current collector 41 of the current wire can be communicated with the battery tab 6 through a large current, and then the battery can be charged and discharged; the voltage line current collector 42 can collect the voltage between the positive and negative electrode battery tabs of the battery after being communicated with the battery tab 6 through small current.
The contact pillar 421 of the current line collector 42 in this embodiment is made of an elastic body, as shown in fig. 6, after an external pressure F is applied to the contact pillar 421 protruding out of the contact plane 411, the protruding elastic body will retract to be flush with the contact plane 411, so as to ensure that the current line collector 41 and the current line collector 42 are both in close contact with the battery tab 6 at the contact plane 411.
As shown in fig. 7, the conductive layer 4 is fixed on the second press plate insulating layer 3 (lower press plate), and the battery tab 6 is put into the battery tab holding device in the manner shown in the drawing; as shown in fig. 8, the first and second laminate insulating layers 2 and 3 provide a stable electrical connection between the battery tab 6 and the conductive layer 4 when the clamping device is closed.
In this embodiment, the contact plane 411 of the current line current collector 41 and the contact column 421 of the voltage line current collector are uniformly distributed in each area of the surface of the conductive layer of the battery tab holding device; the contact pillars 421 are separated from the current line current collector 41 by the insulating interlayer 43, and when the tops of the contact pillars 421 are flush with the contact plane 411, the contact pillars are uniformly distributed on the contact plane 411 at intervals, and the top view structure of the conductive layer 4 is shown in fig. 9; the battery tab 6, whether in contact with the conductive layer 4 in any area, can achieve equal contact with the current line current collector 41 and the voltage line current collector 42, thereby avoiding the problem of prior art in which the clamped battery tab is not in equal contact with the current line and the voltage line.

As a preferred embodiment, the base plate and the spring structure can also be arranged behind the second platen insulation layer, or behind both platen insulation layers.
Obviously, as another implementation manner of the above embodiment, the second platen insulating layer 3 may be used as an upper platen, and the first platen insulating layer 2 may be used as a lower platen, in which case the conductive layer 4 is fixed on the lower platen; for the conductive layer 4 structure, the upper surface of the current line collector 42 may also be provided as a contact plane 411, so that the current line collector 41 has a contact pillar 421, i.e., the structures of the current line collector 42 and the current line collector 41 are interchanged.
