Description
Technical field
The utility model relates to technical field of lithium ion, refers in particular to the close-burning checkout equipment of a kind of electrodes of lithium-ion batteries.
Background technology
Along with the continuous development of modern society, mobile device such as smart mobile phone, notebook computer, video camera and EV (electric automobile) etc. will obtain application more and more widely, thereby form the heavy demand to lithium ion battery.
Pole piece is the core component of lithium ion battery, is the important link in the lithium ion battery production run.The cohesiveness of pole piece directly determines the performance of lithium ion battery, if the cohesive force of pole piece is bad, will have quality problems such as capacity is low, cycle performance is poor, self discharge is fast.So after pole piece was produced, it was particularly important to detect the close-burning work of pole piece.
Existing pole piece cohesiveness detection method mainly contains two kinds in the industry: a kind of is cross-hatching (GB/T9286-88); Promptly on pole piece, mark the grid that intersects anyhow with drawing the lattice device; Making films is scratched, and comes to be that through the observation degree of coming off of filming the pole piece cohesive force judges grade then; Another kind is tension method (CN201464346U), promptly is bonded on the pole piece surface with adhesive tape, with certain speed adhesive tape is separated with pole piece then, and the pulling force that the record adhesive tape separates with pole piece is judged to be the close-burning quality of pole piece through the pulling force size.
Yet, more than two kinds of methods all have very big defective, preceding a kind of owing to receive the influence of gesture and dynamics when drawing lattice, cause testing result to have than large deviation.The influence of pressure when the cohesive force of a kind of because adhesive tape in back and pole piece is pasted, and adhesive tape when separating with pole piece pulling force fluctuate greatlyyer, cause the very difficult judgement of testing result.
The utility model content
The purpose of the utility model is to provide a kind of electrodes of lithium-ion batteries close-burning checkout equipment, can judge the close-burning quality of electrodes of lithium-ion batteries quickly and accurately through this equipment, and then guarantees the performance of lithium ion battery.
The technical scheme of the utility model is following:
The close-burning checkout equipment of a kind of electrodes of lithium-ion batteries; Comprise operator's console; Be arranged on the ultrasonic vibrator in the operator's console; Ultrasonic vibrator is connected with an end of vibration rack, and the vibration rack other end is connected with the style clamps, and the pallet that is arranged on the operator's console and is used with the style anchor clamps.
The principle of work of the utility model: when the ultrasonic energy of ultrasound wave output acts on the electrodes of lithium-ion batteries, can make pole piece generation ultrasonic vibration, this vibration force can make filming on the pole piece come off.Judge the close-burning quality of pole piece through the amount of coming off of filming on the pole piece then.
Said ultrasonic vibrator can apply the ultrasonic vibration of certain hour to the pole piece style by vibration rack and style anchor clamps, and filming on the pole piece come off.
Said style anchor clamps comprise framework, are arranged on fixed head, ambulatory splint and strap in the framework, and described fixed head is fixedly connected with vibration rack, and described fixed head is provided with the adjusting bolt that is used to regulate ambulatory splint.These style anchor clamps can clamp the pole piece style with the form of face contact, so that the pole piece style effectively receives ultrasonic energy.
Said ambulatory splint, fixed head and strap are set in parallel in the framework, and described framework is provided with guide rail.Ambulatory splint can be regulated the position that bolt is regulated ambulatory splint through guide rail parallel moving between framework internal fixation plate and strap, and can it is fastening.
Said vibration rack, style anchor clamps all are metal material, so that effective propagate ultrasonic energy.
Said vibration rack is for falling " L " type, and is easy to install and use.
The beneficial effect of the utility model is:
The close-burning checkout equipment of a kind of electrodes of lithium-ion batteries; Comprise operator's console; Be arranged on the ultrasonic vibrator in the operator's console; Ultrasonic vibrator is connected with an end of vibration rack, and the vibration rack other end is connected with the style clamps, and the pallet that is arranged on the operator's console and is used with the style anchor clamps.This equipment utilization the ultrasonic vibration sent of ultrasonic vibrator, for the cohesiveness of pole piece detects a kind of new method is provided; Traditional cross-hatching is owing to receive the influence of gesture and dynamics when drawing lattice; Cause testing result to have than large deviation, traditional tension method is because the influence of the cohesive force of adhesive tape and pole piece pressure when being pasted, and adhesive tape when separating with pole piece pulling force fluctuate bigger; Cause testing result to be difficult to judge; And the ultrasonic vibration of the utility model characterizes is that pole piece is whole, has shielded the close-burning difference in each position of pole piece, makes testing result more accurate; This operation of equipment is easy, but fast detecting goes out the cohesiveness of pole piece.
Description of drawings
Fig. 1 is the pole piece cohesiveness checkout equipment synoptic diagram in the utility model;
