Description

Technical Field

[0001] This application relates to the field of laser welding technology, and more specifically, to a conical lens assembly and a laser head. Background Technology

[0002] Currently, in 3D wire feeding cladding welding, the laser welding structure generally includes a QBH (Quartz Block Head) optical fiber assembly, a collimating assembly, a conical mirror assembly, a beam splitter assembly, and a focusing mirror assembly. The laser first enters the collimating assembly. After passing through the collimating mirror, the laser beam is emitted through the optical fiber in the optical fiber assembly and irradiates the conical mirror assembly. The conical mirror assembly shapes the laser beam from a solid beam into a hollow beam. The hollow beam then passes through the beam splitter assembly, splitting the beam into two beams, which then irradiate the focusing mirror in the focusing mirror assembly. The two beams are then combined into one, uniformly heating the welding wire from both sides. Only when the optical fiber and the conical mirror assembly are concentrically set can the energy of the hollow beam shaped by the conical mirror assembly be guaranteed to be uniform, ensuring uniform heating of all surfaces of the welding wire and achieving the best welding effect.

[0003] However, in actual use, the upper and lower conical mirrors of the conical mirror assembly are fixed in position by pins or clips. After the laser welding structure is initially assembled, the upper and lower conical mirrors may not be concentric due to assembly and processing errors, which will affect the welding effect.

[0028] like Figures 1 to 4As shown, the conodont assembly 10 provided in this embodiment includes a lens mount 11, an upper conodon 12, an adjusting seat 13, a lower conodon 14, a first gap adjusting assembly 15, and a second gap adjusting assembly 16. The upper conodon 12 is fixed inside the lens mount 11, and the adjusting seat 13 is disposed inside the lens mount 11 and located below the upper conodon 12. A gap G is left between the periphery of the adjusting seat 13 and the lens mount 11. The lower conodon 14 is fixed on the adjusting seat 13. The first gap adjusting assembly 15 can drive the adjusting seat 13 along a first direction D1 (the D1 direction shown in the figure, hereinafter referred to as the first direction). The first gap adjustment component 15 is disposed between the mirror base 11 and the adjustment seat 13, and the second gap adjustment component 16 can drive the adjustment seat 13 to move relative to the mirror base 11 along the second direction D2 (D2 direction shown in the figure, hereinafter referred to as the second direction D2) perpendicular to the first direction D1, so as to adjust the gap G between the adjustment seat 13 and the mirror base 11 in this direction. The second gap adjustment component 16 is disposed between the mirror base 11 and the adjustment seat 13.

[0029] The aforementioned conical lens assembly 10 includes a lens mount 11, an upper conical lens 12, a lower conical lens 14, and an adjustment seat 13. The lower conical lens 14 is mounted on the adjustment seat 13, which is located inside the lens mount 11 with a gap G between it and the lens mount 11. A first gap adjustment component 15 and a second gap adjustment component 16 are used to move the adjustment seat 13 relative to the lens mount 11 in a first direction D1 and a second direction D2 perpendicular to the first direction D1, respectively. In this way, the position of the adjustment seat 13 can be changed in the plane by the first gap adjustment component 15 and the second gap adjustment component 16, thereby adjusting the position of the lower conical lens 14 so that the lower conical lens 14 is coaxial with the upper conical lens 12, so that the shaped optical path reaches an ideal state and the quality of optical path shaping is guaranteed.

[0030] See Figures 1 to 4This embodiment provides a conical lens assembly 10 for beam shaping to obtain a hollow optical path. The conical lens assembly 10 includes a lens base 11, an upper conical lens 12, a lower conical lens 14, and an adjustment seat 13, all of which are installed inside the lens base 11. The upper conical lens 12 is installed at the upper end of the lens base 11 (the upper end shown in the figure), and the lower conical lens 14 is installed at the lower end of the lens base 11 (the lower end shown in the figure) via the adjustment seat 13. In this embodiment, the lens base 11 has, but is not limited to, a rectangular cross-section, including a first side 11a and a second side 11a. b. The third side 11c and the fourth side 11d, wherein the first side 11a is opposite to the third side 11c, and the second side 11b is opposite to the fourth side 11d. The adjusting seat 13 and the mirror mount 11 have a gap G in both the first direction D1 and the second direction D2. Specifically, the side wall of the adjusting seat 13 has this gap G between it and the inner walls of the first side 11a and the third side 11c of the mirror mount 11, as well as between it and the inner walls of the second side 11b and the fourth side 11d of the mirror mount 11. The first gap adjusting assembly 15 can drive the adjusting seat 11c... 3. Move relative to the mirror mount 11 in the first direction D1 to adjust the size of the gap G between the side wall of the adjustment seat 13 and the inner wall of the first side 11a of the mirror mount 11, and between the side wall of the adjustment seat 13 and the inner wall of the third side 11c of the mirror mount 11 in the first direction D1, thereby adjusting the position of the adjustment seat 13 in the first direction D1; the second gap adjustment assembly 16 can drive the adjustment seat 13 to move relative to the mirror mount 11 in the second direction D2 to adjust the size of the gap G between the side wall of the adjustment seat 13 and the inner wall of the second side 11b of the mirror mount 11, and between the side wall of the adjustment seat 13 and the inner wall of the fourth side 11d of the mirror mount 11 in the second direction D2, thereby adjusting the position of the adjustment seat 13 in the second direction D2. In this way, the position of the adjustment seat 13 in the mirror mount 11 can be adjusted in the first direction D1 and the second direction D2 by the first gap adjustment assembly 15 and the second gap adjustment assembly 16 respectively, thereby adjusting the position of the lower conical mirror 14 relative to the upper conical mirror 12 so that the centers of the two can be aligned, improving the beam shaping effect and making the shaped optical path reach the ideal state.

[0031] See Figures 2 to 4The first gap adjustment assembly 15 provided in this embodiment includes a first adjusting screw 151 disposed on one side of the adjustment seat 13 and a first spring 152 disposed on the other side of the adjustment seat 13 opposite to the side where the first adjusting screw 151 is disposed. The first adjusting screw 151 is movably mounted on the mirror seat 11 along the first direction D1 and abuts against the adjustment seat 13. The two ends of the first spring 152 abut against the mirror seat 11 and the adjustment seat 13 respectively. The second gap adjustment assembly 16 includes a second adjusting screw 161 disposed on one side of the adjustment seat 13 and a second spring (not shown) disposed on the other side of the adjustment seat 13 opposite to the side where the second adjusting screw 161 is disposed. The second adjusting screw 161 is movably mounted on the mirror seat 11 along the second direction D2 and abuts against the adjustment seat 13. The two ends of the second spring abut against the mirror seat 11 and the adjustment seat 13 respectively. In this embodiment, the first adjusting screw 151 is disposed on the first side 11a of the lens base 11. The first adjusting screw 151 is threaded to the lens base 11. The outer end of the first adjusting screw 151 is exposed on the surface of the lens base 11, and the inner end abuts against the side wall of the adjusting seat 13. The two ends of the first spring 152 abut against the inner wall of the third side 11c of the lens base 11 and the side wall of the adjusting seat 13 near the third side 11c, respectively. The second adjusting screw 161 is disposed on the second side 11b of the lens base 11. The second adjusting screw 161 is threaded to the lens base 11. The outer end of the second adjusting screw 161 is exposed on the surface of the lens base 11, and the inner end abuts against the side wall of the adjusting seat 13. The two ends of the second spring abut against the inner wall of the fourth side 11d of the lens base 11 and the side wall of the adjusting seat 13 near the fourth side 11d, respectively. It is easy to understand that turning the first adjusting screw in the forward direction... 151. The first adjusting screw 151 moves relative to the mirror base 11 along the first direction D1 to push the adjusting seat 13 and the lower conical mirror 14 to move together, and further compress the first spring 152. The first adjusting screw 151 is turned in the opposite direction, and the elastic force of the first spring 152 will push the adjusting seat 13 and the lower conical mirror 14 to move together in the opposite direction to the first direction D1, thereby realizing the adjustment of the position of the adjusting seat 13 and the lower conical mirror 14 in the first direction D1. Similarly, turning the second adjusting screw 161 can adjust the position of the adjusting seat 13 and the lower conical mirror 14 in the second direction D2. After the adjustment is completed, the positions of the first adjusting screw 151 and the second adjusting screw 161 should not be changed. In this way, the position of the lower conical mirror 14 can be adjusted on a plane parallel to the bottom surface of the mirror base 11, so that the adjusted upper conical mirror 12 and lower conical mirror 14 can be set coaxially.

[0032] In other embodiments, a screw can be used to adjust the position of the adjusting seat 13 in the mirror mount 11. In addition, a nut that cooperates with the screw can be installed on the mirror mount 11, and a spring can be used on the side of the adjusting seat 13 opposite to the screw to provide elastic force.

[0033] See Figures 2 to 4 In this embodiment, the number of first adjusting screws 151 is not limited to one, and the first adjusting screw 151 is located on the center line of the second direction D2. The number of second adjusting screws 161 is not limited to one, and the second adjusting screw 161 is located on the center line of the first direction D1. It can be understood that by setting the first adjusting screw 151 on the center line of the second direction D2, that is, the first adjusting screw 151 is located in the middle position of the first side 11a of the lens, and by setting the second adjusting screw 161 on the center line of the first direction D1, that is, the second adjusting screw 161 is located in the middle position of the second side 11b of the lens, the positions of the first adjusting screw 151 and the second adjusting screw 161 abutting against the adjusting seat 13 are both in the middle position of that side of the adjusting seat 13, thereby ensuring that the force is more even when pushing and the adjusting seat 13 moves more smoothly.

[0034] See Figure 2 and Figure 3 In this embodiment, the number of first springs 152 is not limited to one, and the first spring 152 is located on the center line of the second direction D2. The first spring 152 is coaxial with the first adjusting screw 151. The number of second springs is not limited to one, and the second spring is located on the center line of the first direction D1. The second spring is coaxial with the second adjusting screw 161. In this way, the force on the adjusting seat 13 can be more balanced and the adjustment structure can be more stable.

[0035] See Figures 1 to 3The lens mount 11 provided in this embodiment includes an upper adapter plate 111, a fixed base 112, a pressure plate 113, a mounting base 114, and a lower adapter plate 115 connected sequentially from top to bottom (up and down direction in the figure); an adjustment seat 13 is disposed in the mounting base 114, and there is a gap G between the mounting base 114 and the peripheral side of the adjustment seat 13; the upper conodon 12 is held in the fixed base 112 by the upper assembly assembly 17, and the lower conodon 14 is held in the adjustment seat 13 by the lower assembly assembly 18. In this embodiment, the upper adapter plate 111, the fixed base 112, the pressure plate 113, the mounting base 114, and the lower adapter plate 115 are fixedly connected by screws, bolts, or any other existing fasteners. The upper assembly assembly 17 includes an upper washer 171, an upper fixing ring 172, and an upper pressure ring 173. The upper conical lens 12 is mounted on the fixed base 112 via the upper washer 171. The upper fixing ring 172 can be connected to the fixed base 112 by means of, but is not limited to, threads, and presses the upper conical lens 12 against the upper washer 171. The upper pressure ring 173 is installed... The upper fixing ring 172 and the upper conical lens 12 are held on the fixed base 112. The lower assembly assembly 18 includes a lower washer 181, a lower fixing ring 182, and a lower pressure ring 183. The lower conical lens 14 is mounted on the adjusting base 13 through the lower washer 181. The lower fixing ring 182 can be connected to the adjusting base 13 by means of threads, but is not limited to threads, and presses the lower conical lens 14 against the lower washer 181. The lower pressure ring 183 is mounted on the adjusting base 13 and holds the lower fixing ring 182 and the lower conical lens 14 on the adjusting base 13.

[0036] See Figure 2 and Figure 3 In this embodiment, a height limiting block 19 is provided inside the mirror base 11 to restrict the movement of the adjusting seat 13 relative to the mirror base 11 along its thickness direction (the vertical direction shown in the figure). In this embodiment, a mounting groove 116 is formed on the inner wall of the mounting base body 114 of the mirror base 11, and the height limiting block 19 is disposed in the mounting groove 116. A protrusion 131 is formed on the side wall of the adjusting seat 13, and a limiting groove 191 for the protrusion 131 to slide is formed on the height limiting block 19. In this way, when adjusting the position of the adjusting seat 13 in the first direction D1 and the second direction D2, the adjusting seat 13 is restricted by the height limiting block 19 and cannot move in the thickness direction of the mirror base 11, which can ensure the adjustment accuracy of the structure and improve the stability of the structure.

[0037] Please continue reading Figure 2 and Figure 3In this embodiment, a first sealing member 117 for sealing the gap between the top end of the adjusting seat 13 and the pressure plate 113 of the lens mount 11 is provided.
