[0039] 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.

[0040] like Figures 1 to 9As shown, an automatic laser welding equipment includes: a base 2, a turntable 3, a driving motor 4, a galvanometer 5, a driving device 6, and a lifting mechanism 7. The turntable 3 is rotatably arranged on the base 2. The turntable 3 includes a connecting portion 31 and two placement tables 32 symmetrically arranged on the connecting portion 31. A mold bracket 33 is positioned on the placement table 32, and the mold bracket 33 is used to place the controller 100. The galvanometer 5 is arranged above the turntable 3; the driving motor 4 is fixed on the base 2, and the output shaft of the driving motor 4 is transmission-connected with the connecting portion 31 of the turntable 3 to drive the turntable 3 to rotate; the driving device 6 is connected to the galvanometer 5 to drive the galvanometer 5 to move in the X-axis, Y-axis and Z-axis directions; the galvanometer 5 is used to laser weld the controller 100; the lifting mechanism 7 is installed on the base 2, and the lifting mechanism 7 is used to lift the mold bracket 33 on the corresponding placement table 32 and bring it close to the galvanometer 5.

[0041] In the present application, the corresponding mold bracket 33 is replaced according to the shape of the controller 100 .

[0042] The mold holder 33 can be placed on both placement tables 32, and the controller 100 can be placed on each mold holder 33. When the controller 100 on the corresponding mold holder 33 is being processed, the controller 100 on the other mold holder 33 can be replaced, and the replacement and laser processing can be carried out simultaneously to achieve production continuity.

[0043] The driving motor 4 is fixed on the base 2, and the output shaft of the driving motor 4 is connected to the connecting portion 31 of the turntable 3, so as to drive the turntable 3 to rotate, and the turntable 3 transfers the welded controller 100 to the outside, or transfers the unwelded controller 100 to a preset position, so that it is aligned with the galvanometer 5 for laser welding. The welded controller 100 can be manually removed and a new controller 100 can be placed, which can be carried out simultaneously with the welding work.

[0044] After the controller 100 is transferred to the preset position, the lifting mechanism 7 is started to lift the controller 100 on the mold support 33 to the bottom of the galvanometer 5. The lifting mechanism 7 makes the controller 100 close to the laser welding area of ​​the galvanometer 5 to ensure that the controller 100 is within the focusing range of the laser. The drive device 6 is connected to the galvanometer 5, and the galvanometer 5 is driven by the drive device 6 to move in the X-axis, Y-axis and Z-axis directions. The galvanometer 5 controls the precise position and angle of the laser beam and focuses the laser beam on the controller 100 for welding. During the laser welding process, the laser is irradiated to the specified position of the controller 100 through the galvanometer 5 to achieve high-precision welding. In this application, the drive device 6 is a prior art and can be purchased directly on the market.

[0045] In the present application, the driving device 6 is a prior art and can be directly purchased on the market.

[0046] Specifically, Figure 4 , Figure 5 As shown, the mold support 33 includes a plurality of positioning plug-ins 331 , a plurality of support columns 332 , and quick clamps 333 corresponding to the support columns 332 one by one.

[0047] The position of the controller 100 can be accurately determined through the positioning plug-in 331, and it can be inserted into the positioning hole of the controller 100 so that the position of the controller 100 can be kept consistent each time. The controller 100 can be supported to a preset height through the support column 332, and the controller 100 can be quickly clamped and fixed through the quick clamp 333.

[0048] Specifically, Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the placement table 32 is provided with a plurality of lifting holes 321, and the lifting mechanism 7 includes a fixed bracket 71, a lifting bracket 72, and a servo electric cylinder 73. The fixed bracket 71 is fixed on the base 2, and the lifting bracket 72 is connected to the fixed bracket 71 through a plurality of telescopic rods 74. A plurality of ejector rods 721 corresponding to the lifting holes 321 are fixed to the upper end of the lifting bracket 72, and the ejector rods 721 can pass through the lifting holes 321 to lift the mold bracket 33; the lifting bracket 72 has two parallel plate bodies 722, and each plate body 722 is provided with two inclined guide holes 7221, and the first end 72211 of each guide hole 7221 is higher than the second end 72212 of the guide hole 7221 The servo electric cylinder 73 is fixed on the fixed bracket 71, a driving frame 731 is fixed on the push rod of the servo electric cylinder 73, a guide rail 711 is fixed on the fixed bracket 71, the driving frame 731 is slidably connected with the guide rail 711, four guide wheels 7311 are fixed on the driving frame 731, the four guide wheels 7311 are respectively arranged in four guide holes 7221, and can move along the guide holes 7221, wherein, when the guide wheel 7311 is located at the first end 72211 of the guide hole 7221, the lifting bracket 72 is located at the first position, and when the guide wheel 7311 is located at the second end 72212 of the guide hole 7221, the lifting bracket 72 is located at the second position, and the second position is higher than the first position.

[0049] In the present application, the fixed bracket 71 of the lifting mechanism 7 is fixed on the base 2, the servo electric cylinder 73 is fixed on the fixed bracket 71, the push rod of the servo electric cylinder 73 is connected to the driving frame 731, the driving frame 731 is slidably connected to the fixed bracket 71 through the guide rail 711, and the lifting bracket 72 is connected to the fixed bracket 71 through a plurality of telescopic rods 74. The upper end of the lifting bracket 72 is provided with a plurality of push rods 721, and these push rods 721 can pass through the lifting holes 321 on the placement table 32.

[0050] The four guide wheels 7311 on the driving frame 731 are respectively arranged in the inclined guide holes 7221 on the two parallel plates 722 of the lifting bracket 72. The first end 72211 of the guide hole 7221 is higher than the second end 72212, so that the movement of the lifting bracket 72 has the characteristic of vertical lifting. The servo electric cylinder 73 drives the driving frame 731 to move along the guide rail 711 by controlling the extension and contraction of the push rod, thereby driving the lifting bracket 72 to rise and fall.

[0051] When the push rod of the servo electric cylinder 73 extends, the driving frame 731 moves along the guide rail 711. The four guide wheels 7311 slide in the inclined guide hole 7221, so that the upper end push rod 721 of the lifting bracket 72 passes through the lifting hole 321, driving the mold bracket 33 to rise. The position of the guide wheel 7311 determines the height of the lifting bracket 72. Specifically, when the guide wheel 7311 is at the first end 72211 of the guide hole 7221, the lifting bracket 72 is in the first position, at which time the height of the mold bracket 33 is relatively low; when the guide wheel 7311 moves to the second end 72212 of the guide hole 7221, the lifting bracket 72 rises to the second position, at which time the height of the mold bracket 33 is relatively high.

[0052] The lifting bracket 72 is lifted and lowered by the movement of the guide wheel 7311 in the guide hole 7221. Due to the inclined design of the guide hole 7221, the lifting bracket 72 can move smoothly between the upper and lower positions. The second position is higher than the first position, which can ensure that the mold bracket 33 is within the required height range.

[0053] When the mold support 33 needs to be close to the galvanometer 5 for laser welding, the servo electric cylinder 73 drives the lifting support 72 to rise, so that the mold support 33 reaches the second position, ensuring that the controller 100 is within the focal range of the laser welding. After the welding is completed, the servo electric cylinder 73 can control the lifting support 72 to descend back to the first position, so as to facilitate the removal or replacement of the mold support 33.

[0054] Specifically, Figure 5 As shown, a plurality of positioning pins 7211 are fixed to the upper end of the ejector pin 721 , and an insertion hole 334 corresponding to the positioning pins 7211 is provided on the mold support 33 , and the positioning pins 7211 can be inserted into the insertion hole 334 to limit the translation of the mold support 33 .

[0055] After the positioning pin 7211 is inserted into the insertion hole 334, the mold support 33 can be accurately fixed to prevent it from being translated due to vibration or external force during the welding process, thereby ensuring the stability of the position of the controller 100. The precise positioning function ensures that the controller 100 is always within the focal range of the laser welding, avoiding inaccurate welding due to position error, and improving welding quality and consistency.

[0056] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 As shown, it also includes a dust collecting device 8, which includes a mounting plate 81, a fixing plate 82, a recovery pipe 83, a dust collector 84, a pressing block 85, and a positioning plate 86. The mounting plate 81 is provided with a mounting hole 811, and the fixing plate 82 is fixed at the mounting hole 811 of the mounting plate 81. The fixing plate 82 is provided with two first strip-shaped through holes 821. The lower part of the mounting plate 81 is fixed with two limit blocks 812 distributed on both sides of the mounting hole 811. The limit blocks 812 are provided with limit card grooves 8121. The two ends of the positioning plate 86 are respectively clamped in the limit card grooves 8121. The positioning plate 86 is provided with a second strip through hole 861 corresponding to the first strip through hole 821. The positioning plate 86 A plurality of pressing blocks 85 are fixed at the lower end, and a through channel 851 is provided in the middle of the pressing block 85, the upper end of the channel 851 is aligned with the first strip through hole 821, and the lower end of the channel 851 is used to align with the welding position on the controller 100, and the lower end of the pressing block 85 can be against the controller 100, wherein the first strip through hole 821, the second strip through hole 861, and the channel 851 are used for the laser emitted by the galvanometer 5 to pass through; one end of the recovery pipe 83 is passed through the fixed plate 82, and the other end is connected to the dust collector 84, and a recovery cover 831 is fixed at one end of the recovery pipe 83, and the recovery cover 831 is arranged between the two first strip through holes 821 and arranged along the length direction of the first strip through hole 821.

[0057] During the laser welding process, smoke will be generated, which can be removed through the dust collector 84, the recovery pipe 83, and the recovery cover 831.

[0058] After the lifting bracket 72 moves up, the pressing block 85 can be pressed against the controller 100, and its channel 851 is aligned with the position of the controller 100 that needs to be welded. At this time, the laser can pass through the first bar-shaped through hole 821, the second bar-shaped through hole 861 and the channel 851, and contact the controller 100 for welding. The smoke generated by welding can be recovered by the recovery cover 831 along the channel 851 and the second bar-shaped through hole 861. When the pressing block 85 is pressed against the controller 100, the heat generated by laser welding can be quickly transferred through the pressing block 85 to avoid affecting other parts of the controller 100. When the laser generates smoke, the channel 851 on the pressing block 85 can absorb the smoke through the channel 851. The channel 851 increases the suction force at this position and better absorbs the smoke; at the same time, it protects other components on the controller 100, and the laser can only be emitted into the area corresponding to the channel 851 to ensure accurate welding. In the present application, the pressing block 85 is made of metal.

[0059] In the present application, when the positioning plate 86 is installed in the limiting slot 8121 , it is clamped and fixed by the two limiting blocks 812 at the same time.

[0060] like Figure 8 As shown, the recovery cover 831 has an inner cavity 8311 , and has two protrusions 8312 aligned with the second strip-shaped through holes 861 , a slit 83121 is provided on the protrusion 8312 , the slit 83121 is connected to the inner cavity 8311 , and the recovery pipe 83 is connected to the inner cavity 8311 .

[0061] The inner cavity 8311 of the recovery cover 831 is connected to the recovery pipe 83, and is connected to the inner cavity 8311 through the gap 83121 on the protrusion 8312, so that the smoke generated during the welding process can be efficiently sucked away to keep the working environment clean. The protrusion 8312 is aligned with the second strip through hole 861 and is connected to the inner cavity 8311 through the gap 83121, thereby concentrating the suction force on the area where the welding smoke is generated, thereby improving the efficiency and effect of smoke recovery. The precise suction area can also reduce the temperature of the area without blocking the path of the laser.

[0062] Specifically, Figure 3 , Figure 7 As shown, a plurality of pressure posts 822 are fixed on the positioning plate 86 , and the pressure posts 822 are used to press tightly on the controller 100 .

[0063] The pressure column 822 can firmly press the controller 100 against the mold support 33 to prevent it from moving during the welding process, thereby ensuring the accuracy and consistency of welding. A plurality of pressure columns 822 are distributed around the controller 100, and a plurality of pressure columns 822 are distributed on the positioning plate 86, which can evenly apply pressure to avoid deformation or damage of the controller 100 caused by a single point of force, thereby protecting the integrity of the controller 100.

[0064] Specifically, Figure 1 , Fig. 9 As shown, it also includes a box body 9, the driving device 6 and the galvanometer 5 are arranged in the box body 9, and the box body 9 is provided with a lower box door 91 and an upper box door 92, and there is a gap 93 between the lower box door 91 and the upper box door 92; two symmetrically arranged blocking components 34 are fixed on the connecting part 31, and the blocking components 34 and the connecting part 31 can block the gap 93.

[0065] The closed box 9 design reduces the chances of direct contact between the operator and the laser and mechanical moving parts, improves the safety of the operation process, and prevents accidental injuries. The closed box 9 design is conducive to the control of the internal temperature. By setting a cooling system or vents in the box 9, it is ensured that the drive device 6 and the galvanometer 5 work in a stable temperature environment, thereby improving the performance and stability of the equipment.

[0066] During actual operation, one of the placement platforms 32 will enter the box body 9 , while the other placement platform 32 will be exposed outside the box body 9 .
