In order to increase the interactivity of people and equipment, above-mentioned PLC control system can also comprise human-computer interaction interface, specifically can be embodied as console, control panel etc., control platform as shown in Figure 5, and it is connected with PLC, is used to import instruction, parameter, display parameters etc.
Because what the driver part that among the present invention cutter is driven adopted is stepper motor, therefore, described length control module goes out the length of the aluminium alloy foil material that transmits on the corresponding with it feeding roller according to the real-time displacement data computation of stepper motor.Characteristic and control algolithm thereof according to stepper motor, the stepper motor rotating speed can be controlled by adjusting pulse frequency, and stepper motor rotational angle or displacement can be controlled by number of pulses, can determine angular displacement according to the umber of pulse in the unit interval, according to rotate a week used umber of pulse and the size of motor determine the displacement of the lines of every degree, with the multiply each other length of the aluminium alloy foil material that can obtain transmitting on the feeding roller of the displacement of the lines of angular displacement and every degree.
Adhesive tape recognition unit in the control system of the present invention, as one embodiment of the present of invention, this adhesive tape recognition unit comprises laser sensor 2 and signal processing circuit thereof, as shown in Figure 4, laser sensor 2 is installed on the frame of feeding roller 4, the visual red laser beam that the sensing head 2.1 of laser sensor 2 sends is radiated at foil bar 1 surface on the feeding roller 4, this sensing head sends to its information that senses after signal processor 2.2 carries out preliminary treatment, send to control system, be the PLC control system herein.When the material on foil bar 1 surface not simultaneously, the sensing value that obtains is also different, therefore, promptly knows adhesive tape or foil bar by judging the sensing value that laser sensor 2 senses.
Control system of the present invention adopts PLC (Programmable Logic Controller) controller and accessory circuit thereof that data are handled, and also can adopt other processors and peripheral circuit thereof certainly, as, single-chip microcomputer and accessory circuit thereof.The signal of each sensor in its receiving device, the signal that sends according to each sensor or calculate after the data that obtain carry out control corresponding.For example, the control step rotating speed of motor, control synchronous motor starting, stop.Its accessory circuit comprises power circuit, interface circuit, memory circuit etc.For example, in a specific embodiment, some memories can be set in accessory circuit, be used to store shearing predetermined length, adhesive tape width or adjacent two adhesive tape spacings of aluminium alloy foil material.
Before the equipment operation, operating personnel input to PLC by man-machine interface (being generally control platform form) with the cut-to-length value L of aluminium foil, the parameters such as distance values s of adhesive tape.The operation of system comprises initialization and two processes of normal operation.
When initialization:
1. make the operation of feeding roller crawl by the control platform to feeding roller stepper motor sending controling instruction;
2. making feeding roller transport the slit that foil passes between the upper and lower scissors of shearing machine stops to the closed assembly platform, make the light beam spot of laser sensor aim at foil part between two adhesive tape of foil on the feeding roller, and with the signal processor of aluminium foil to the influence value input laser sensor of laser beam;
3. then continue to make the operation of feeding roller crawl, and make light beam spot aim at the front of certain adhesive tape along (pressing the traffic direction of adhesive tape, edge by light beam claims the edge, front earlier, the edge of back by light beam claims back edge) after stop, if this light beam spot is the c point, and with the signal processor of adhesive tape to the influence value input laser sensor of laser beam;
4. the crawl cutter is sheared foil.
5, the predetermined sheared length L by control platform input foil, and be that the foil length calculation is handled starting point with the c point.
Through after the above-mentioned initialization, can normally move, promptly start feeding roller and begin to move automatically and shear foil.
In the foil running, the PLC control system is according to the umber of pulse of feeding roller stepper motor, i.e. the displacement data of stepper motor, calculate the real-time length of foil, when the running length of foil equates with preseting length, send the shearing instruction by the PLC control system, carry out by cutter and shear.
In order to reduce the inertia of foil operation, avoid the foil bar to exceed clipped position, cause the error of sheared length, can also set in advance the length that runs slowly.When foil moves to certain preset distance length of closing on shearing point, the PLC control system is sent deceleration instruction to the stepper motor of feeding roller, stop when making foil slowly move to length L, then send and shear instruction by the PLC control system, carry out shearing by cutter, thereby guarantee the accuracy of sheared length.
The present invention can make the error of Cutting Length L be controlled in the 0.05mm scope, can realize the high accuracy of honeycomb hole lattice length of side a=0.5-1mm foil is sheared.
In addition, in order to guarantee that shearing function cuts off foil, the start bit of scissors and Zhongdao position are provided with upper photoelectric sensor 3.1 and the next photoelectric sensor 3.2 on cutter, following level sensor 3.2 signal that will put in place is sent to PLC, cut off foil to represent this action, in addition, by this signal is counted, can calculate the foil number of closed assembly.The work of counting can be finished by counter, and this counter can be that software is realized, promptly adopts one section counting procedure to finish, and also can adopt hardware counter to finish.
In addition, in the present invention, the uniformity for the adhesive tape spacing of monitoring the preorder coating technique need detect the adhesive tape spacing of reality.Can adopt s=4a to represent known adhesive tape distance values, adopt parameter s ' represent the instantaneous value (measured value) of adhesive tape spacing in service.When initialization, can be by control platform input s value, when the operation foil, calculate s ' value and demonstration in real time by laser sensor and through PLC, if the two equates that illustrate that the width of adhesive tape and spacing are correct, then the position behind the closed assembly also can be correct, s ' is if conversion is indefinite or depart from the s value, whether the gluing that then need check glue spreader in front is evenly correct, and whether tension force is suitable, the surface quality of aluminium foil, laser sensor is taked corresponding measure then to identification quality of adhesive tape and aluminium foil etc.
Foil is after initialization, as long as adhesive tape spacing uniformity, the sheared length of every foil is accurately consistent, each foil justify align when closed assembly, and then the position of each layer adhesive tape after the stack will be correct.Wherein, by the uniformity of coating technique control assurance adhesive tape spacing, the accuracy by above-mentioned shearing control system assurance foil Cutting Length guarantees the alignment of each foil by the closed assembly platform.
Aluminium alloy foil material described in the present invention is an aluminium or based on the aluminium alloy of aluminium, for example, the trade mark that can adopt is that 3003H18,5052H24 etc., thickness are the aluminium alloy foil material of 0.02-0.06mm.
