Description

Line laser marker

Technical field

The utility model relates to a kind of line laser marker; Particularly relate to the line laser marker of locating with cursor line on a kind of tyre building machine.

Background technology

Line laser marker is arranged on the assembly drum of tyre building machine, the top of band bundle drum peace drum, be a kind of equipment of in the tire building process semi-manufacture on drum being fitted and carrying out cursor positioning, the small product size that existing line laser marker such as patent 01274798.X describe is big and be split type, in use installing space is big and connect up loaded down with trivial details, use chain and step motor drive, the repetitive positioning accuracy less trouble is higher, communication interface is 8421 yards interfaces, loaded down with trivial details with upper machine communication, the repair demolition difficulty, the moving cursor spacing range is little, and the beacon light live width can not adjust and can only be applied to fixed range and use, and its purchase cost is also than higher.The line laser marker that another patent 200720099885.0 is described rely on linear bearing cooperate form that leading screw drives when needing the bigger specification of spacing because of fixing at two ends, cause the leading screw can be because of the gravity deformation center section waist that collapses, cause mobile laser lamp socket not parallel and asymmetric, cause precision to reduce.

Summary of the invention

Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, the graticule device of the servo positioning that the precision that provides a kind of beacon light live width to adjust flexibly is high can be applicable to the plurality of specifications make-up machine, and line laser marker little and that be structure as a whole takes up room.

The technical scheme that the utility model adopted is: a kind of line laser marker comprises control device, mechanical driving device and laser focus control; Described control device is the PLC Programmable Logic Controller; Described mechanical driving device comprise motor, synchronously the band and line slideway, described line slideway is provided with the laser lamp bracket, described PLC Programmable Logic Controller is electrically connected with motor by cable, the motor shaft of synchronous pulley and motor is fixed, described synchronous band is connected between synchronous pulley and the engaged wheel, and the line slideway of band drive synchronously moves; Described laser focus control comprises left and right and middle laser lamp, and described laser lamp is installed on the described laser lamp bracket.

Described motor is a servomotor.

Described laser lamp is selected for use and can be adjusted spherical mirror and then change focal length, and the live width that guarantees Laser emission is less than 0.5mm.

Described laser lamp bracket comprises left and right and middle laser frame; The laser frame is fixedly mounted on the center of line slideway in described, during described left and right laser frame slidably is installed on the line slideway of the left and right sides of laser frame.

This newly with novel beneficial effect is: new pattern laser graticule device cost is low, installation and wiring are simple and take up room little, be provided with simple during with the make-up machine communication, accurate positioning, error are little, failure rate is low, the beacon light live width can be adjusted flexibly, uses versatility stronger, can be applicable to the tyre building machine of plurality of specifications.

Embodiment

Fig. 1 is the front view figure of line laser marker; The 2nd, the upward view of line laser marker; Fig. 3 is the side view of line laser marker.As shown in Figure 1 to Figure 3, the utility model line laser marker comprises, control device, mechanical driving device and laser focus control; Described control device is a PLC Programmable Logic Controller 10, described mechanical driving device comprises servomotor 20, is with 30 and line slideway 40 synchronously, selecting servomotor for making the location more accurate, is to lean on the engagement of tooth to come transmission with 30 synchronously, and the ratio of gear during synchronously with transmission is accurate, acting force to servomotor and follower shaft is little, compact conformation, oil resistant, wearing quality is good, ageing resistance is good, so the utility model selects synchronous band can guarantee the speed and the precision of locating; The PLC Programmable Logic Controller is electrically connected with motor by cable, synchronous pulley 31 is fixed with the motor shaft of motor, describedly be with 30 to be connected between synchronous pulley 31 and the engaged wheel 32 synchronously, synchronous pulley 31 by motor-driven drive synchronously with on line slideway move or locate, described laser focus control comprises left and right and middle laser lamp, described laser lamp is installed on the laser lamp bracket, and described laser lamp bracket is installed on the line slideway, and the laser lamp bracket supports each left and right and middle laser lamp respectively; Laser frame 70 is fixedly mounted on the center of line slideway 40 in described, during described left laser frame 50 right laser framves 60 are slidingly mounted on the line slideway of the left and right sides of laser frame, move or locatees along line slideway.The beacon light live width can be adjusted flexibly, moving cursor maximum spacing 2000mm, minimum spacing 45mm, described laser lamp select for use and can adjust spherical mirror and then change focal length, the live width that guarantees Laser emission is not more than 0.5mm, and the make-up machine that can be applicable to all size uses versatility stronger.

The course of work of the present utility model is described as follows: line laser marker PLC Programmable Logic Controller receives make-up machine by communication cable and communication module and instructs laggard row operation, send the operation of instruction control servomotor, servomotor is by belt wheel and bring synchronously and drive the laser lamp socket be installed on the line slideway and move and locate, laser beam becomes on the desired location that graticule is radiated at tyre building machine, feeds back virtual condition simultaneously and gives host computer.Promptly, the graticule device powers on, and (the PLC Programmable Logic Controller sends instruction to back initialization self-zeroing, carry out initialization, return zero according to the optoelectronic switch that is arranged on the left and right spacing and reference origin place on the line slideway) wait for the instruction of make-up machine at tire minimum widith place, then, needs according to tyre building machine, carry out manual unlocking, manual closing in specialized range, return actions such as zero and location, locating speed can be by instruction map.In addition, when using the make-up machine of different size, graticule device and assembly drum change apart from meeting, need to adjust the lamp line of laser lamp this moment, laser lamp adopts varifocal form, change focal length by adjusting spherical mirror, thereby guarantee that laser lamp lamp line minimum feature (being not more than 0.5mm) reduces the error of laser positioning.
