Description
Technical field:
The present invention relates to the Apparatus and method for of a kind of constant current belt-sanding mechanism and constant current sanding electronic circuit board, belong to sander and make the field.
Background technology:
All number of patent applications of the applicant are 200410080060.5, title " sander dynamic workpiece and abrasive band are to zero device and to zero method ", this sander dynamic workpiece and abrasive band are to zero method, workpiece is placed horizontally on the sander work transport platform, when the conveyer belt of work transport platform is slowly sent into workpiece under the sanding touch roll that sander is equipped with the abrasive band, the work transport platform raises, workpiece face in conveyer belt contacts and drives the moment that rotate in the abrasive band with the abrasive band, the signal that rotate in its abrasive band exports controller to, and controller instruction works transport platform stops to rise, this moment, finished zeroing in workpiece and abrasive band.
Summary of the invention:
Purpose of design: design a kind of can be according to the variation of abrasive band drive motors electric current, accurately control the heave amplitude of work top, guarantee to be reached the sanding requirement, not by the saturating constant current belt-sanding method of sand, reach the sanding effect of typical products in mass production uniformity again by the wiring board of sand.
If ground scheme: in order to realize above-mentioned purpose of design.1 manual sample repeatedly, select the current work parameter of the current work parameter of best sample as automatic sanding, it is one of feature of the present invention, because the Copper Foil skin of electronic circuit board is all extremely thin, adopt conventional abrasive finishing method to carry out sanding, its sanding amount is difficult to control, and is careless slightly, copper sheet on its wiring board is will sand broken, cause the monoblock electronic circuit board scrap and work efficiency very low.In order to solve this difficult problem, the application by the control to the abrasive band current of electric, reaches the control to the abrasive finishing machine abrasive finishing amount on the basis of existing sander.Concrete way is: before the sanding of batch electronic circuit board, at first carry out manual sanding sample, (every all has numbering) finds out best one in the manual sample of polylith, and the current data of this piece electronic circuit model is input in the PLC controller, current work parameter during as automatic sanding, the current parameters that sander sets according to the PLC controller is controlled the heave amplitude of work top automatically by servomotor, workbench control elevating mechanism, thereby reaches efficiently, accurately, nondestructively electronic circuit board is carried out sanding.
Technical scheme 1: the control method of constant current belt-sanding, 1. manual sample, to be inserted between abrasive band and work top by the electronic circuit board of sand, manually adjust work top and try sand, current data during with each sanding is all noted down or is recorded in automatically in the PLC controller, manually several electronic circuit models to institute's sand compare, find out best one, find out the current data of this piece electronic circuit model then and be set to the current data of the automatic sanding of PLC controller and comprise the upper and lower bound of current data; 2. sanding automatically, the current data that sander sets according to PLC is adjusted the height of work top automatically in to the sanding process of electronic circuit board, thereby reaches best sanding effect.
Technical scheme 2: constant current belt-sanding controlling organization, the abrasive band assembly drives main motor and is provided with current detection sensor, the signal output part of current detection sensor connects the signal input part of PLC controller, and the signal output part of PLC controller connects the signal input part of servomotor in the work top elevating mechanism and control and waits for an opportunity the working method and the workload of motor.
The present invention compares with background technology, determine the operating current of belt sander in the sander by manual sample, not only can find out to precision by the best sanding precision of electronic circuit board, and can determine the operating current parameter of sander abrasive band motor according to this precision; The 2nd, the current parameters of manual sample the best of selecting is set at the current work parameter of automatic sanding, not only can accurately control the heave amplitude and the duty of sander work top, and reach efficiently, at a high speed, high accuracy, unabroken automatic sanding.
Description of drawings:
Fig. 1 is the structural representation of constant current belt-sanding mechanism.
The specific embodiment:
Embodiment 1: with reference to accompanying drawing 1.Constant current belt-sanding controlling organization, the abrasive band assembly drives main motor 11 and is provided with current detection sensor, current sampling is taken from the operating current of abrasive band motor, the signal output part of current detection sensor connects the signal input part of PLC controller 2, the signal output part of PLC controller 2 connects the signal input part of servomotor 10 in the work top elevating mechanism and control and waits for an opportunity the working method and the workload of motor, that is to say that the servomotor in the work top elevating mechanism is controlled by the variation of abrasive band roll drive motor operating current by the PLC controller.What match with PLC control is touch-screen control display 1.The abrasive band assembly is made of parts such as drive roll 5 and driven voller 3, abrasive bands 4, and its fabrication and installation technology is prior art, is not described herein at this.Work worker face elevating mechanism is made of parts such as worker's elevating mechanism 9, servomotors 10, and servomotor is by the lifting of elevating mechanism control work top, and its fabrication and installation technology is prior art, is not described herein at this.Work top 6 is made of parts such as conveying roller, motor 7 and conveyer belts, and its fabrication and installation technology is prior art, is not described herein at this.Servomotor is by the lifting of elevating mechanism control work top.Be positioned on the conveyer belt by the electronic circuit board 8 of sand and through the abrasive band assembly time by sanding.
Embodiment 2: on the basis of embodiment 1, the control method of constant current belt-sanding, 1. manual sample, to be inserted between abrasive band and work top by the electronic circuit board of sand, manually adjust work top and try sand, current data during with each sanding is all noted down or is recorded in automatically in the PLC controller, manually several electronic circuit models to institute's sand compare, find out best one, find out the current data of this piece electronic circuit model then and be set to the current data of the automatic sanding of PLC controller and comprise the upper and lower bound of current data; 2. sanding automatically, the current data that sander sets according to PLC is adjusted the height of work top automatically in to the sanding process of electronic circuit board, thereby reaches best sanding effect.3. in PLC control during the no-load running of abrasive band, the unloaded operation current settings of abrasive band motor is the out-of-work instruction of work top.
