Description

Laser printing and carving integrated equipment for machining

Technical Field

The invention relates to the field of laser printing equipment, in particular to laser printing and engraving integrated equipment for machining.

Background

The laser engraving processing is based on the numerical control technology, and laser is a processing medium. The physical denaturation of the processing material due to instant melting and gasification under the irradiation of laser engraving can enable the laser engraving to achieve the purpose of processing. The laser printing for machining refers to laser engraving, which is to engrave characters on an object by using a laser technology, wherein the characters engraved by the technology have no nicks, the surface of the object is still smooth, and the handwriting is not abraded.

However, when the plate workpiece is subjected to laser printing or laser engraving, the marks left on the plate are different due to the material of the plate, the required depth of the plate and the energy of laser, so that the processed effect is different; although a lifting support frame is arranged in the closed laser engraving machine (CN201711111893.7), the quick lifting of the lifting support frame is realized through a threaded lifting shaft and a related structure which are arranged in an upright post, and the structure is more compact; but the device can not assist the user to quickly find the proper engraving data; therefore, a laser printing and engraving integrated device for machining is provided.

The principle of the invention is explained below, before carving the material, the material of the plate and the distance between the laser head 8 and the plate will affect the depth of carving and the color of carving; therefore, proper parameters need to be found before the workpiece is carved; firstly, a second screw 12 is driven to rotate by a sixth motor 49, and the two second screws 12 are driven to move in the opposite direction by meshing a first bevel gear and a second bevel gear, so that the first sliding seat 10 drives the roller 7 to move in the opposite direction; then, the first electric push rod 30 is driven to drive the connecting seat 24 to move, the connecting seat 24 drives the connecting rod 33 to swing through the sliding block 34, after the connecting rod 33 swings, the baffle 31 is driven to move downwards through the second chain 32, the conveying frame 35 moves downwards, then a test board or a waste board is placed on the rolling shaft and reset, the two sides of the column-shaped plate are clamped by the rollers 7, then the second motor 16 is started, the second motor 16 drives the second rotating shaft 14 to rotate through the bevel gear, the first chain wheel and the second chain 32 are driven to rotate, the first rotating shaft 13 is driven to rotate, and the plate is driven to move to the position below the friction block 6 through the two rollers 7; meanwhile, the bottom plate 47 is driven by the motor IV to move upwards, so that the end surface of the base 48 is flush with the bottom surface of the plate; at this time, because the bevel gear six 27 in the connecting mechanism is not meshed with the bevel gear four 19, the straight gear two 29 is not meshed with the straight gear one 28, and the friction block 6 is not moved; then the laser head 8 starts to work, circular proofing is carried out, then the screw rod I is controlled to rotate through the driving motor I4, the laser head 8 is further made to move up and down, and in the moving process, the distance data between the laser head 8 and the plate are recorded through a main control computer; after the engraving of the plate is finished, selecting proper parameters according to the printing condition; after proofing, the plate is quickly placed into the movable platform 5 through the steps, the clamping assembly drives the gear shaft 41 to rotate through the motor III 42, and further drives the straight gear III 39 screw rods IV 37 to rotate, so that the clamping block I36 is driven to move, and the clamping block I36 clamps two sides of the plate; then, the connecting seat 24 is driven to move by the electric push rod II 45, so that the bevel gear six 27 is meshed with the bevel gear four 19, the straight gear I28 is meshed with the straight gear II 29, the baffle plate 31 moves upwards, and the baffle plate 31 and the base 48 seal the movable platform 5; then, the workpiece is pushed to abut against the baffle 31 through the second electric push rod 45, so that the positioning of the workpiece is completed; then, the second motor 16 is started, and the third screw 22 is driven to rotate through the connecting mechanism, so that the second sliding seat 23 is moved to the initial position of laser printing or engraving; at the moment, the sliding seat II 23 wipes and removes dust on the inner side and the outer side of the glass and the surface of the workpiece through the friction block 6 and the friction strip; then before the laser head 8 starts to act, the second sliding seat 23 moves a little distance along the carving track; then the laser head 8 carries out sweeping type carving, the sliding seat II 23 moves along with the laser head 8, and the fan intermittently works in the carving process to remove dust; when the glass is in batch operation, the laser head 8 can cause the surface of a workpiece to generate smoke, scraps and the like when the glass works, the glass can prevent the smoke from spreading to the outside, the base 48 removes dust through the fan, and partial particles can be adhered to the surface of the glass, and the scraps can be blown away by partial scraps due to the action of the fan; through the mode, the second sliding seat 23 prevents the sweeps from being blown away to the unprocessed area of the workpiece, and can remove dust on the inner side surface and the outer side surface of the glass, so that the influence on laser engraving is avoided, and the quality of the laser engraving is improved. In addition, during batch processing, the feed inlet can be selected to be the roller 7 side or the bottom plate 47 side according to actual conditions.

Further, a fixed frame is fixedly arranged on the workbench 1; a screw rod six is fixedly arranged on the fixed frame; the screw six is in threaded connection with the movable platform 5; the screw rod six is connected through a synchronous belt; the screw rod six is driven by the motor five.

Further, the movable platform 5 is fixedly provided with three first sealing plates at the upper end of the bottom plate 47; a second sealing plate is rotatably connected with the second sealing plate; the first sealing plate and the second sealing plate form a sealed channel. Because some machined parts are machined and need to be carved, the machined parts cannot enter from the openings of the rollers 7, the machined parts can be put into the bottom plate 47 in the above mode, and smoke is prevented from being scattered to the outside.

Furthermore, a first strong magnet is fixedly arranged inside the friction block 6; a second strong magnet is fixedly arranged on the second sliding seat 23; the strong magnet I and the strong magnet II attract each other; facilitating replacement of the inner pad 6.
