Description

Technical Field

[0001] This invention relates to the field of laser processing, and in particular to a laser processing head adjustment base and control method. Background Technology

[0002] Laser engraving is the most common application of laser systems. Based on the mechanism of interaction between the laser beam and the material, laser processing can be broadly divided into two categories: laser thermal processing and photochemical reaction processing. During processing, the laser processing head needs to be manipulated to emit a laser beam onto the surface of the object to generate a thermal effect and achieve the processing. Existing laser processing heads are generally moved by a set dual-rail mechanism. For example, Chinese invention patent CN101318412B discloses a laser marking and cutting integrated machine, which specifically includes a laser, an X-axis drive mechanism, and a Y-axis drive mechanism. The laser is moved by the cooperation of the X-axis drive mechanism and the Y-axis drive mechanism. However, the cooperation of the two can only achieve single-plane movement of the laser. It cannot perform comprehensive engraving operations on three-dimensional engraving objects, and its practicality is poor. Summary of the Invention

[0003] The purpose of this invention is to provide a laser processing head adjustment base and control method. This invention allows the laser to rotate in various directions, facilitating laser processing of three-dimensional engraved objects and offering excellent practicality.

[0004] The technical solution of this invention: A laser processing head adjustment base includes a fixed plate, a drive motor on the fixed plate, an output shaft at the output end of the drive motor, and an annular internal gear rotatably connected to and surrounding the output shaft on the end face of the drive motor; an outer ring surrounding the annular internal gear is provided on the fixed plate, the inner ring surface of the outer ring having internal teeth, and an intermediate gear meshing between the outer ring and the annular internal gear; a support plate is provided on the fixed plate, and an outer sleeve rotatably connected to and coaxial with the output shaft is provided on the support plate, with an inner rotating shaft rotatably connected to and coaxial with the output shaft inside the outer sleeve; a connecting rod rotatably connected to the middle of the intermediate gear is provided at one end of the outer sleeve. The outer sleeve has a mounting rod at the other end; the inner rotating shaft has a first bevel gear at its end, the mounting rod has a second bevel gear meshing with the first bevel gear at its end, the second bevel gear has a rotating rod in the middle, and the rotating rod has a connecting seat at its end; the output shaft has a slidingly connected adjusting block, both ends of the adjusting block have rubber contact surfaces, the inner edge of the annular inner gear and the end of the inner rotating shaft have contact grooves that fit with the corresponding rubber contact surfaces; the fixed plate has an adjusting motor, the adjusting motor has an adjusting rod at its end, the adjusting rod has an arc-shaped locking block at its end, and the adjusting block has an annular locking groove in the middle that matches the arc-shaped locking block.

[0005] In the aforementioned laser processing head adjustment base, the adjustment rod is provided with multiple vertically arranged limiting blocks, each limiting block is provided with a vertically arranged limiting groove, and the end of the adjustment rod is provided with a movable rod that matches the limiting groove.

[0006] In the aforementioned laser processing head adjustment seat, the outer sleeve is provided with a first locking disc, the mounting rod is located on the edge of the first locking disc, and the end of the inner rotating shaft is provided with a second locking disc located between the first locking disc and the first bevel gear; the side of the movable rod is provided with a locking rod, the support plate is horizontally movably connected to the locking rod, and the end of the locking rod is provided with locking plates arranged inside and outside, the inner locking plate corresponding to the first locking disc and the outer locking plate corresponding to the second locking disc.

[0007] In the aforementioned laser processing head adjustment seat, the side of the support plate is provided with a horizontal limiting sleeve that is adapted to the locking rod.

[0008] In the aforementioned laser processing head adjustment seat, the groove surface of the bonding groove is a conical surface, and the rubber bonding surface is a conical surface that fits into the bonding groove.

[0009] In the aforementioned laser processing head adjustment seat, the connecting rod includes a crossbar connected to the intermediate gear, and the end of the crossbar is provided with a vertical plate connected to the outer sleeve.

[0010] In the aforementioned laser processing head adjustment seat, the rotating rod is L-shaped.

[0011] The aforementioned control method for the laser processing head adjustment seat involves adjusting the motor to drive the adjusting rod, causing the adjusting block to move inward so that the rubber contact surface mates with the contact groove of the annular internal gear. At this point, after the drive motor starts, it drives the annular internal gear to move via the output shaft and the adjusting block. This, in conjunction with the inner teeth of the outer ring, drives the intermediate gear to rotate around the annular internal gear. This, in turn, drives the outer sleeve to rotate via the connecting rod, thus enabling the connecting seat to revolve around the output shaft. Alternatively, adjusting the motor to drive the adjusting rod to move the adjusting block outward so that the rubber contact surface mates with the contact groove of the inner rotating shaft. At this point, after the drive motor starts, it drives the inner rotating shaft to rotate via the output shaft, thus driving the first bevel gear to rotate. The first bevel gear then drives the second bevel gear to rotate, achieving the rotation of the connecting seat.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention includes a fixed plate with a drive motor, an output shaft at the output end of the drive motor, and an annular internal gear rotatably connected to and surrounding the output shaft at the end face of the drive motor; the fixed plate has an outer ring surrounding the annular internal gear, the inner ring surface of the outer ring having internal teeth, and an intermediate gear meshing with both the outer ring and the annular internal gear; the fixed plate has a support plate, and the support plate has an outer sleeve rotatably connected to and coaxial with the output shaft, and an inner rotating shaft rotatably connected to and coaxial with the output shaft within the outer sleeve; one end of the outer sleeve has a connecting rod rotatably connected to the middle of the intermediate gear, and the other end of the outer sleeve has a mounting rod; the end of the inner rotating shaft has a first bevel gear, the end of the mounting rod has a second bevel gear meshing with the first bevel gear, the middle of the second bevel gear has a rotating rod, and the end of the rotating rod has a connecting seat; the output shaft has a slidingly connected adjusting block, both ends of the adjusting block having rubber contact surfaces, and the inner edge of the annular internal gear and the end of the inner rotating shaft both having corresponding rubber contact surfaces. The device features a mating groove for the rubber mating surface. An adjusting motor is mounted on the fixed plate, with an adjusting rod at one end and an arc-shaped locking block at the other. The adjusting block has an annular groove in its center that matches the arc-shaped locking block. The adjusting motor drives the adjusting rod to move the adjusting block inward, causing the rubber mating surface to mate with the mating groove of the annular inner gear. Upon starting, the driving motor moves the annular inner gear via its output shaft and the adjusting block. This, in turn, causes the inner gear of the outer ring to rotate around the annular inner gear, which in turn drives the outer sleeve to rotate via the connecting rod, enabling the connecting seat to revolve around the output shaft. Alternatively, the adjusting motor drives the adjusting rod to move the adjusting block outward, causing the rubber mating surface to mate with the mating groove of the inner rotating shaft. Upon starting, the driving motor rotates the inner rotating shaft via its output shaft, which in turn drives the first bevel gear to rotate. The first bevel gear then drives the second bevel gear to rotate, enabling the connecting seat to rotate. Through the rotation and revolution of the connecting seat, the laser connected above can rotate in multiple directions, providing a hardware foundation for the processing of three-dimensional engraved objects.

[0014] 2. The adjusting rod of the present invention is provided with multiple vertically arranged limiting blocks, and each limiting block is provided with a vertically arranged limiting groove. The end of the adjusting rod is provided with a movable rod that matches the limiting groove. The movable rod can move and rotate within the limiting groove to adapt to the position and angle changes caused by the rotation of the adjusting rod. The outer sleeve is provided with a first locking disc, and the mounting rod is provided on the edge of the first locking disc. The end of the inner rotating shaft is provided with a second locking disc located between the first locking disc and the first bevel gear. The side of the movable rod is provided with a locking rod, and the support plate is horizontally movably connected to the locking rod. The end of the locking rod is respectively provided with... It has locking plates with inner and outer sides. The inner locking plate corresponds to the first locking disc, and the outer locking plate corresponds to the second locking disc. When the adjusting rod rotates and drives the adjusting block to engage with the inner ring gear, the outer locking disc also moves with the locking rod and is tightly attached to the second locking disc to achieve fixation. The fixing effect of the first bevel gear prevents the second bevel gear from rotating on its own. When the adjusting rod rotates and drives the adjusting block to engage with the inner rotating shaft, the inner locking disc is tightly attached to the first locking disc to achieve fixation, preventing the second bevel gear from revolving. The two movement modes do not interfere with each other, effectively improving the accuracy of the adjustment process. Attached Figure Description
