Description
Technical field
The utility model relates to the color television set process units, is that raw-material planar mask is produced the steel band deviation correcting device with sheet metal in the color television set production particularly.
Background technology
In existing color television set production, be that the tuningout of steel band in the raw-material planar mask production is regulated with cylinder always with sheet metal, the station of tuningout has only two: i.e. left end and right-hand member, because middle no transition point, therefore regulated quantity is bigger, cause the steel band swing excessive, cause product to roll over the deviation that injures the aperture easily, influence the grade of product quality and product.Its reason is the version of original system and actuator is unreasonable, the amplitude of accommodation is excessive.
Summary of the invention
The purpose of this utility model is that above the deficiencies in the prior art are improved, change two station designs of steel band tuningout in the existing planar mask production into continuous adjusting, according to requirements such as the moment of deviation correcting device, adjustment amounts, select reducing motor as actuator, PLC is as main control device, and the mode that governor motion adopts leading screw, screw, slide rail to combine with linear bearing is finished in planar mask is produced the tuningout in the steel band running.
The purpose of this utility model is finished by the following technical solutions, this technical scheme comprises: deviation correcting device is by bearing, regulating roller and steel band are formed, one end of regulating roller connects universal bearing and drives the steel band operation, this device also is provided with crank, universal bearing, guide rail, reducing motor, shaft coupling, leading screw, screw, linear bearing, slide rail and base, wherein, the other end connecting crank and the universal bearing of regulating roller, universal bearing is fixed on the guide rail, crank is fixed on screw and two linear bearings, nut sleeve is contained on the leading screw, leading screw links to each other with reducing motor by shaft coupling, two linear bearings of leading screw both sides link to each other with slide rail respectively, leading screw, slide rail is installed in respectively on the base, and two limit switches are installed at the two ends of base bottom.
Aborning, position transducer detects edge, steel band both sides respectively, and signal delivered to PLC, by programming, turning to and amount of spin of control motor, governor motion is delivered to regulating roller with motor action, reaches to regulate the make peace purpose of raising tuningout precision of steel band run location center and equipment center one.

Specific embodiments
Below in conjunction with accompanying drawing the utility model is described in more detail.
With reference to Fig. 1 steel band deviation correcting device structure chart, when work, regulating roller 2 drives steel band 15 operations, one end of regulating roller 2 is connected with universal bearing 1, other end connecting crank 3 and universal bearing 4, universal bearing 1 are fixed on the equipment stand, and universal bearing 4 is fixed on the guide rail 5, guarantee that regulating roller 2 is a basic point with universal bearing 1, again can be when rotating along guide rail 5 side-to-side movements.Crank 3 rectangular bendings are installed on screw 9 and two linear bearings 10, and screw 9 is sleeved on the leading screw 8, and leading screw 8 is connected by the output shaft of shaft coupling 7 with reducing motor 6; Leading screw 8, slide rail 11 are installed in respectively on the base 12.When motor 6 rotates, drive leading screw 8 and rotate, drive cranks 3 by linear bearing 9 and move, motor turn to difference, regulate the direction difference.In order to guarantee crank 3 easy motions, designed slide rail 11 in the both sides of leading screw 8,2 linear bearings 10 of leading screw 8 both sides link to each other with slide rail 11 respectively; Two ends in base 12 bottoms are equipped with limit switch 13 and 15, improving the reliability of system, take place to prevent to collide when unusual in system.
With reference to the steel band deviation correcting device control system block diagram of Fig. 2, steel band 15 is provided with transducer 16,17,18,19 and transducer 20, and transducer 16,17 detects the edge on steel band both sides, with reflection steel band running status; Transducer 18,19 detects the narrower conduction band edge of wide cut, and transducer 20 is used for distinguishing of steel band, conduction band; Console switch 21 is used for the execute-in-place of deviation system, have manually, automatically, left side action, right action etc.; Detection signal and console switch are sent into PLC 22, and control program begins to handle input signal, and how decision tuningout motor moves, and frequency converter 23 is sent in the motor action instruction, drive reducing motor 24 motions by frequency converter.
With reference to the control program flow chart of Fig. 3, when console switch 21 was positioned at manual position, the tuningout action was controlled by limit switch only by the hand switch operation.When console switch 21 is positioned at automated location, regulate beginning, sensor steel band running status automatically; When transducer 16,17 is connected simultaneously, illustrate that steel band is in the center, no tuningout action; Transducer 16 is connected, when transducer 17 disconnects, illustrate that steel band takes over, and produces the action of a tuningout left side; Transducer 17 is connected, when transducer 16 disconnects, illustrate that steel band takes back, and produces that tuningout is right to move.The process of left side action and right action is identical, and when operation condition satisfied, tuningout moved for the first time, T1 second operate time; Operation condition satisfies t1 second continuously, tuningout action for the second time, T2 second operate time; Operation condition satisfies t2 second continuously, tuningout action for the third time, and T3 second operate time, operation condition satisfies t3 second continuously, the 4th tuningout action, T4 second operate time; The tuningout action of one-period is finished in so circulation.In the tuningout process of one-period, as long as operation condition does not satisfy, the tuningout release of this cycle, get back to starting point at once---detect the steel band running status, restart the tuningout action of following one-period.The set point of each timer can online modification, to reach the optimum adjustment effect.
The utility model has the advantage of with reducing motor to replace cylinder, realized on the macroscopic view continuously Regulate, guaranteed that production process steel band center and equipment center coincide, and have improved steel band and have moved Tuningout degree of regulation in the journey reduced folding and hindered and can eliminate the deviation in aperture, improved product Grade and yields.
