Description

Technical Field

[0001] The present invention relates to the technical field of laser swing welding, and more specifically, to a handheld laser processing device supporting laser swing welding. Background Art

[0002] A small handheld laser processing device, such as a laser processing head or a handheld laser, has been increasingly accepted by the manufacturing industry due to its efficient welding performance and lightweight welding method.

[0003] The handheld laser processing device is very sensitive to the angle of the laser light path during assembly and welding. In particular, the assembly process is limited by the processing accuracy of parts, making it difficult to meet the design accuracy requirements. The manufacturing yield is low, and there are fatal problems such as reduced welding quality or burning of the gun tip due to the deviation of the light path.

[0004] Due to the size of the small handheld laser processing device, the existing galvanometer assembly can only achieve one-dimensional swing and calibration functions through a large motor, and cannot achieve two-dimensional swing calibration. It can only be manually adjusted and calibrated repeatedly during installation, which is time-consuming and difficult to adjust to the ideal angle due to the manufacturing accuracy and assembly techniques. The assembly efficiency and manufacturing yield are low. If you want to achieve multi-dimensional swing, you need to set up large motors in multiple directions, which takes up a large volume. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned defects of the prior art and to provide a handheld laser processing device that can not only realize the two-dimensional swing calibration of the galvanometer assembly with high precision but also has a small size and is more suitable for application in small laser processing heads or handheld lasers.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] A handheld laser processing device supporting laser swing welding, comprising a handheld welding gun housing and a galvanometer assembly, a drive module, an electrical connector and a oscillator swing assembly contained in the handheld welding gun housing;

[0008] The driving module is sealed and packaged in the housing of the handheld welding gun, and the driving module includes a base and a frame support body arranged on the base, and a receiving cavity is arranged in the middle of the frame support body. The driving module also includes a plurality of groups of first magnetic components and second magnetic components, and the first magnetic components and the second magnetic components of each group cooperate with each other, and the first magnetic components are fixed on the inner wall of the receiving cavity, and the second magnetic components are fixedly connected to the vibrator swing assembly;

[0009] The vibrator swing assembly is arranged in the accommodating cavity and can move relative to the driving module, the side of the vibrator swing assembly facing away from the driving module is fixedly connected to the galvanometer assembly, and the electrical connector is arranged on the side of the base facing away from the frame support body;

[0010] Assume that the axial direction of the galvanometer assembly is the Z axis, the X axis and the Y axis are respectively perpendicular to the Z axis, the electrical connector is electrically connected to the driving module, and is energized to generate magnetic force to drive the galvanometer assembly to swing according to a preset mode.

[0011] Implementing the embodiments of the present invention will have the following beneficial effects:

[0012] The embodiment of the present invention drives the vibrator swing assembly to swing around the X-axis and the Y-axis through the driving module. The movement of the vibrator swing assembly drives the galvanometer assembly to move synchronously, and can realize the two-dimensional swing and calibration function of the galvanometer assembly, which not only simplifies the assembly difficulty and improves production efficiency, but also enhances the precise control of the optical path direction, improves the accuracy and quality of laser welding, and avoids burning the gun head body. On the other hand, the present invention can seal the laser channel by sealingly connecting the driving module with the housing of the handheld welding gun; by arranging the electrical connector on the side of the driving module away from the galvanometer assembly, the electrical connector is installed outside the laser channel, which not only avoids the influence of high temperature on the electrical connector, but also facilitates the electrical connection and assembly of other components with the electrical connector.

[0013] In summary, the structure of the embodiment of the present invention can not only realize the two-dimensional swing calibration of the galvanometer assembly with high precision, but also has a small size, and is more suitable for application in small laser processing heads or handheld lasers. The required angle is achieved through software calibration, reducing the dependence on structural accuracy and assembly techniques, effectively improving assembly efficiency and manufacturing yield. At the same time, due to its flexible swing amplitude, it can adapt to various complex welding conditions and beautify weld functions, realizing one machine with multiple functions. At the same time, it overcomes various problems such as non-standard, special-shaped, and wide welds, and realizes true full-scene coverage welding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] refer to Figure 1 to Figure 6The present invention discloses a handheld laser processing device supporting laser swing welding, comprising a handheld welding gun housing (not shown in the figure) and a galvanometer assembly 10, a driving module 30, an electrical connector 40 and a vibrator swing assembly 60 contained in the handheld welding gun housing; the driving module 30 is sealed and packaged in the handheld welding gun housing, the driving module 30 comprises a driving shell 20, the driving shell 20 comprises a base 21 and a frame support body 22 arranged on the base 21, a receiving cavity 23 is arranged in the middle of the frame support body 22, the driving module 30 further comprises a plurality of groups of first magnetic components 31 and second magnetic components 32, each group of the first magnetic components 31 and the second magnetic components 32 cooperate with each other, After power is turned on, magnetic drive can be generated. The first magnetic component 31 is fixed on the inner wall of the accommodating chamber 23. The second magnetic component 32 is fixedly connected to the vibrator swing assembly 60 (further to the vibrator 50). The vibrator swing assembly 60 is arranged in the accommodating chamber 23 and can move relative to the driving module 30. The side of the vibrator swing assembly 60 that is away from the driving module 30 is fixedly connected to the galvanometer assembly 10. The electrical connector 40 is arranged on the side of the base 21 that is away from the frame support body 22. The axial direction of the galvanometer assembly 10 is set as the Z axis, and the X axis and the Y axis are respectively perpendicular to the Z axis. The electrical connector 40 is electrically connected to the driving module 30. Power is turned on to generate magnetic force to drive the galvanometer assembly to swing according to a preset mode. Specifically, the driving module 30 drives the vibrator 50 to swing around the X axis and the Y axis, and the movement of the vibrator 50 drives the galvanometer assembly 10 to move synchronously.

[0026] The embodiment of the present invention drives the vibrator swing assembly 60 to swing around the X-axis and the Y-axis through the driving module 30. The movement of the vibrator swing assembly 60 drives the galvanometer assembly 10 to move synchronously, and can realize the two-dimensional swing and calibration function of the galvanometer assembly 10, which not only simplifies the assembly difficulty and improves production efficiency, but also enhances the precise control of the optical path direction, improves the accuracy and quality of laser welding, and avoids burning the gun head body. On the other hand, the present invention can seal the laser channel by sealing the driving module 30 with the housing of the handheld welding gun; by setting the electrical connector 40 on the side of the driving module 30 away from the galvanometer assembly 10, the electrical connector 40 is installed outside the laser channel, which not only avoids the high temperature from affecting the electrical connector 40, but also facilitates the electrical connection and assembly of other components with the electrical connector 40.

[0027] In summary, the structure of the embodiment of the present invention can not only realize the two-dimensional swing calibration of the galvanometer assembly 10 with high precision, but also has a small size, and is more suitable for application in small laser processing heads or handheld lasers. The required angle can be achieved through software calibration, reducing the dependence on structural accuracy and assembly techniques, effectively improving assembly efficiency and manufacturing yield, and at the same time, due to its flexible swing amplitude, it can adapt to various complex welding conditions and beautify the weld function, realizing one machine with multiple functions.

Among them, the number of the second connecting parts 615 is not limited to two, and can also be a plurality of spaced arrangements. Figure 4 The shape of the second connecting portion 615 shown in the figure is (or close to) an S-shape or a bow-shape, which helps to reduce the stress on the second connecting portion 615, the outer ring body 612 and the inner ring body 613, and greatly improves the deformation resistance of the spring structure.

[0029] The two first fixing parts 611 are respectively arranged on the outer sides of the outer ring body 612 along the X-axis direction, and the two first fixing parts 611 are respectively connected to the outer ring body 612 through the first connecting parts 614. The number of the first connecting parts 614 is not limited to two, and can also be multiple and spaced. Figure 4 The first connecting portion 614 shown in the figure is in an S-shape or a bow-shape (or close to it), which helps to reduce the stress on the first fixing portion 611 and the outer ring body 612 and greatly improves the deformation resistance of the spring structure.

[0030] Optionally, the width dimensions corresponding to the second connection portion 615 and the first connection portion 614 can be appropriately set according to the weight, volume, area and other information of the galvanometer assembly 10. The bending shape is not limited to that shown in the figure, and can be an S-shaped or bow-shaped structure with multiple sections connected in sequence. Or it can be an S-shaped or bow-shaped structure with multiple sections of gradually changing width connected in sequence, so as to disperse the stress at the turning point.

[0031] In addition, the configuration of the first fixing portion 611 is not limited to the structure of the positioning column and the positioning hole, and can be inserted on the frame support body 22, or a foldable structure with the same effect as gluing is included in the scope of the present application. At the same time, the structure also has strong stability, and prevents the galvanometer assembly 10 from shifting and causing its accuracy to be low during the falling or assembly process.

[0032] The second fixing portion 616 is disposed on the inner side of the outer ring body 612 . The second fixing portion 616 is connected to the outer ring body 612 in the Y-axis direction via the second connecting portion 615 .

Figure 5 , the second fixing portion 616 may also be a structure similar to the first fixing portion 611 .

[0035] In the above technical solution, the driving module 30 can drive the outer ring body 612 to rotate around the X-axis, and the outer ring body 612 rotates around the X-axis to drive the inner ring body 613 and the galvanometer assembly 10 to rotate synchronously. The driving module 30 can also drive the inner ring body 613 to rotate around the Y-axis, and the inner ring body 613 rotates around the Y-axis to drive the galvanometer assembly 10 to rotate synchronously. The driving module 30 can also drive the inner ring body 613 to move up and down along the Z-axis, so that the inner ring body 613 drives the galvanometer assembly 10 to move up and down along the Z-axis. Therefore, in addition to realizing two-dimensional swing calibration around the X-axis and the Y-axis, the shrapnel 61 of the present technical solution can also realize focusing along the Z-axis direction.

[0036] For further reference, Figure 1 and Figure 3 The number of groups of the first magnetic member 31 and the second magnetic member 32 is four, two of which are arranged in the X-axis direction and are symmetrical about the axis of the galvanometer assembly 10, and the other two are arranged in the Y-axis direction and are symmetrical about the axis of the galvanometer assembly 10. The deflection of the inner ring body 613 and the outer ring body 612 can be driven by controlling the magnetic force F of the four groups of the first magnetic member 31 and the second magnetic member 32. The position and direction of the magnetic force F acting on the spring 61 are as shown in FIG. Figure 3 shown.

[0040] refer to Figure 6 In another specific embodiment, the vibrator swing assembly 60 may also include a ball joint support member 62, a support plate 63 and a vibrator 50, wherein the two ends of the ball joint support member 62 are respectively connected to the base 21 and the support plate 63, the support plate 63 can move, and the two sides of the support plate 63 are respectively fixedly connected to the vibrator 50 and the galvanometer assembly 10.

The other end of the support rod 621 that is away from the first ball-joint connection portion 622 is fixedly connected to the base 21. In this specific embodiment, since one end of the ball-joint support member 62 is fixedly connected to the base 21, it cannot provide movement along the Z-axis direction, and can only provide rotation around the X-axis and the Y-axis.

In this specific embodiment, movement along the Z axis direction can be provided, as well as rotation around the X axis and the Y axis can be provided.

[0044] The number of ball joint support members 62 is at least one, preferably five, one of which is located on the axis of the galvanometer assembly 10 , and the remaining four are evenly distributed around, which can improve the stability of the support plate 63 .

[0045] refer to Figure 2 and Figure 3 In a specific embodiment, the outer wall of the frame support body 22 is provided with an outwardly protruding assembly step 222, and the inner wall of the handheld welding gun housing is provided with a matching step that matches the assembly step 222.

[0046] Preferably, a sealing ring is further included, and the sealing ring is arranged between the assembly step 222 and the matching step to provide better sealing.

[0047] In a specific embodiment, the handheld laser processing device further includes an angle detection sensor, which is disposed on the driving module 30 and is used to detect the swing angle of the galvanometer assembly 10 to achieve swing amplitude calibration and improve the swing accuracy.

[0048] In a specific embodiment, the handheld laser processing device further includes a cooling module, which is disposed between the galvanometer assembly 10 and the vibrator swing assembly 60, and is used to cool the galvanometer assembly 10. The cooling module may specifically be a semiconductor cooling sheet or a liquid coolant cooling module. The cooling module may also be a metal heat sink, which may be a single-layer metal sheet with good thermal conductivity, and the cooling module may further include a metal sheet and heat dissipation fins disposed on the metal sheet.

[0049] In another specific embodiment, the handheld laser processing device also includes a cooling air duct and a purge air duct. The cooling air duct leads to the back of the galvanometer assembly 10, and the purge air duct leads to the laser processing head. A part of the cooling gas is diverted to dissipate the heat of the galvanometer assembly 10 through the cooling air duct, and the other part is blown toward the workpiece surface through the purge air duct.

[0050] The cooling module and the cooling air duct may be provided at the same time or separately.

[0051] refer to Figure 1 In a specific embodiment, the galvanometer assembly 10 includes an optical lens 11 and a lens fixing member 12. The optical lens 11 is fixed on the lens fixing member 12. The lens fixing member 12 is fixed to the oscillator swing assembly 60. Specifically, the lens fixing member 12 is fixedly connected to the spring 61. In the present invention, the optical lens 11 is preferably a galvanometer lens, which converges and reflects the laser emitted by the laser generator into the laser channel and emits it through the nozzle.

[0052] Better, reference Figure 7 In another embodiment, a lens clamping structure 121 extends outward from the outer edge of the lens fixing member 12 to fix the optical lens 11. Specifically, the lens clamping structure 121 can be a buckle claw, or a buckle structure for clamping the optical lens along the thickness direction, etc.

[0053] Preferably, in a specific embodiment, the handheld laser processing device further includes a dust cover, which is used to prevent dust in the laser channel (located on the side of the galvanometer assembly 10 away from the driving module 30) from entering the interior of the drive.

[0055] In order to adapt to the swing welding, the handheld laser processing device also includes a barrel and a nozzle, and the outer diameter of the nozzle is larger than the outer diameter of the barrel. By installing a nozzle with a larger outer diameter on the barrel, it can be used for swing welding, increase the width of the weld, make the 4mm weld a thing of the past, conquer the 6mm wide weld, and the maximum width can reach 8mm.

[0056] Wide weld welding not only tests the performance of the equipment, but also requires the operator to learn and be familiar with traditional arc welding techniques, such as bridging and lap welding. The laser oscillating welding method, which uses galvanometer swing and hand swing, greatly reduces the difficulty of welding. Therefore, users can flexibly adjust the welding strategy according to actual needs, whether pursuing a wider weld width or a deeper penetration effect, they can do it with ease.

[0057] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
