Description

Lamination machine with the on-line automatic monitoring of battery diaphragm defective

Technical field

The utility model and a kind of lamination machine with the on-line automatic monitoring of battery diaphragm defective belong to dynamo-electric field.

Background technology

In the production process of lithium ion battery, battery lamination technology is one of very important link, in the lamination process control of diaphragm quality is directly influenced the qualification rate and the security performance of battery finished product, existing laminating equipment has then lacked in the lamination process this link of control to diaphragm quality, cause the barrier film defective to only depend on hand inspection, the problem thin excessively to the barrier film part only depends on subjective judgement, not only increase labour intensity but also lacked strict effectively yardstick, randomness is very strong, can't accurately determine the zone of defective film, buried hidden danger for the electric core quality of producing, in case the problems such as short circuit that appearance causes because of the barrier film defective, often need to do over again, influenced production efficiency.

In order to overcome the problem that the judgement of diaphragm quality is only depended on artificial subjective judgement, can decay after by barrier film according to infrared ray, its attenuation with membrane thicknesses reduce and the principle that reduces has designed a kind of lamination machine with the on-line automatic monitoring of battery diaphragm defective.

The utility model content

The purpose of this utility model provides a kind of lamination machine with the on-line automatic monitoring of battery diaphragm defective, with solving the problem that can not accurately monitor the barrier film that has defective in the lamination machine lamination process.

For achieving the above object, the utility model adopts following technical scheme: a kind of lamination machine with the on-line automatic monitoring of battery diaphragm defective, comprise the lamination machine, barrier film spool on this lamination machine frame and barrier film drive the body of the barrier film between the wheel by the both sides in path are provided with signal emission and the signal receiver that a defects detection is used, the line of signal receiver is connected into a signal-processing board, this signal-processing board is connected with warning device and control switch circuit, the control switch circuit is connected the start and stop of control motor with the drive motors that drives wheel, also is provided with the knob of manual actuation to wheel on this lamination machine.

Described signal emission and signal receiver are a pair of infrared and infrared induction device, and the infrared induction device mainly is made of the line array CCD photoelectric sensor.

The beneficial effects of the utility model are: be provided with by the maximum to the infrared ray light intensity that receives in the signal-processing board, can satisfy the critical thickness of the different battery diaphragms that require, infrared signal after seeing through the battery diaphragm decay is input to signal-processing board and compares with the maximum of setting, during greater than the maximum set, signal-processing board sends signal and the motor of wheel is quit work for control switch circuit controlling and driving, send alarm signal simultaneously, the convenient position that manually marks the defective barrier film accurately, remove until alarm signal by the transmission of rotary knob control barrier film, can not only determine the position of defective barrier film so exactly, also can accurately determine the zone of defective barrier film, make things convenient for manual intercept defective barrier film, cut the waste, also avoid the battery quality problems such as electric core short circuit that cause because of the barrier film defective, improved production efficiency.

Fig. 2 is a theory diagram of the present utility model.

Embodiment

Fig. 1, shown in Figure 2 schematic diagram of the present utility model and theory diagram, compriselamination machine 1, the body of barrier film by the both sides in path that barrier film spool 2 on thislamination machine 1 frame and barrier film drive taking turns between 5 is provided with a pair ofinfrared transmitting device 3 andinfrared induction device 4, the output ofinfrared induction device 4 is connected into a signal-processing board, this signal-processing board is provided with warning device and control switch circuit, control switch circuit and barrier film drive and are connected and control the motor start andstop taking turns 5 drive motors, also be provided with the knob 6 of manual actuation on thelamination machine 1 to wheel, whereininfrared induction device 4 is the line array CCD photoelectric sensor, and warning device is the buzzing warning device.

Operation principle of the present utility model is: because infrared ray sees through the membrane degradation degree of different-thickness is different, the thin more decay of film is more little, therefore, thickness according to required battery diaphragm is benchmark, set the maximum of infrared ray light intensity, the infrared induction device of employing line array CCD photoelectric sensor can accurately be sensed the light signal strength after the decay of barrier film each point, therefore as long as the light intensity that the line array CCD photoelectric sensor is a bit sensed has surpassed the maximum of setting, signal-processing board sends signal and quits work for the control switch circuit control motor that barrier film drives wheel, send alarm signal simultaneously, the operator just can mark the position of defective barrier film accurately, transmit until alarm signal by rotary knob control barrier film then and remove, just can accurately determine the zone of defective barrier film.
