DETAILED DESCRIPTION
[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0026] Example 1, reference Figure 1 to Figure 7, which is the first embodiment of the present invention, and provides a new energy vehicle frame laser welding device, which can realize the effect of automatically and quickly replacing the protective lens 104 on the laser welding gun 101, and comprises a welding component 100, comprising a laser welding gun 101, an emission area 102 arranged on the laser welding gun 101, a protective ring 103 arranged on the emission area 102, and a protective lens 104 arranged on the protective ring 103; a replacement component 200, comprising a flip assembly 201 arranged on the laser welding gun 101 , a gear assembly 202 arranged on the flip assembly 201, a transmission assembly 203 arranged on the gear assembly 202, a guide assembly 204 arranged on the transmission assembly 203, and a power assembly 205 arranged on the guide assembly 204; the protective component 300 includes a shielding assembly 301 arranged on the laser welding gun 101, a pushing assembly 302 arranged on the shielding assembly 301, a pumping assembly 303 arranged on the pushing assembly 302, and an opening assembly 304 arranged on the shielding assembly 301.
[0027] Specifically, the outer end of the laser welding gun 101 is connected to a robot, which can drive the laser welding gun 101 to rotate or move in multiple directions. The emitting area 102 can emit laser to heat up the welding point. The above is the existing technology and will not be elaborated here.
[0028] Further, the flip assembly 201 includes a plurality of U-shaped plates 201a fixedly connected to the side wall of the laser welding gun 101, the plurality of U-shaped plates 201a are rotatably connected to a rotating shaft 201b, the rotating shaft 201b is fixedly connected to an inclined plate 201c, the inclined plate 201c is fixedly connected to a horizontal plate 201d, the plurality of horizontal plates 201d are fixedly connected to a carrying ring 201e, and the plurality of carrying rings 201e are provided with a replacement lens 201f; the gear assembly 202 includes a plurality of U-shaped plates 201a arranged on the inclined plate 201 c, a first gear 202b is rotatably connected in the notch 202a, and a first tooth plate 202c meshing with the first gear 202b is slidably connected to the U-shaped plate 201a; the transmission assembly 203 includes an L-shaped plate 203a fixedly connected to the first tooth plate 202c, an arc plate 203b is fixedly connected to the L-shaped plate 203a, and multiple arc plates 203b are spliced into a ring shape, and the L-shaped plate 203a is elastically connected to the L-shaped plate 203a through a first spring 203c.
[0029] Among them, the setting of the inclined plate 201c makes it possible for the inclined plate 201c to fit with the side wall of the laser welding gun 101 when the substitute lens 201f does not block the emission area 102, so that during the welding process, it is not easy to collide with the workpiece to be welded, which facilitates welding. The supporting ring 201e here leaves a certain distance from the emission area 102, so that when the laser welding gun 101 is working, it is not easy for the supporting ring 201e to collide with the workpiece to be processed. The L-shaped plate 203a here corresponds to the substitute lens 201f one by one. The substitute lens 201f here is not fixed with the protective lens 104. The one on the lower side of the emission area 102 is the protective lens 104, and the other is the substitute lens 201f.
[0030] Preferably, the guide assembly 204 includes a first arc groove 204a provided on the side wall of the laser welding gun 101, the first arc groove 204a is connected to the second arc groove 204b, the second arc groove 204b is connected to the third arc groove 204c, the third arc groove 204c is connected to the fourth arc groove 204d, the third arc groove 204c is located on the upper side of the first arc groove 204a, the first arc groove 204a, the second arc groove 204b, the third arc groove 204c, and the fourth arc groove 204d are all provided in plurality, and the first arc groove 204a, the second arc groove 204b, the third arc groove 204c, and the fourth arc groove 204d are all provided in plurality. A slide bar 204e is provided in the arc groove 204a; the power assembly 205 includes a circular ring 205a fixedly connected to the side wall of the laser welding gun 101, and a ring-shaped electric slide rail 205b is provided on the circular ring 205a. A slider 205c is slidably connected to the electric slide rail 205b, and a U-shaped seat 205d is fixedly connected to the slider 205c. The U-shaped seat 205d is slidably connected to an L-shaped bar 205e, and the horizontal side of the L-shaped bar 205e extends to the lower side of the arc plate 203b, and the slide bar 204e is fixedly connected to the upper end of the L-shaped bar 205e.
[0031] It should be noted that multiple arc plates 203b are spliced into a ring shape to ensure that there will be an arc plate 203b and an L-shaped strip 205e against each other at any time. The second arc groove 204b and the fourth arc groove 204d are symmetrically arranged here, and the first arc groove 204a, the second arc groove 204b, the third arc groove 204c, and the fourth arc groove 204d are a group, and the first arc groove 204a and the fourth arc groove 204d between two adjacent groups are connected. The ring 205a here is far away from the launch area 102, so that during welding, the ring 205a does not contact the workpiece to be processed.
[0032] When the protective lens 104 is in use, the first spring 203c on the L-shaped plate 203a corresponding to the protective lens 104 is extended, and the slide bar 204e is in the third arc groove 204c. When the protective lens 104 is damaged and needs to be replaced, it is only necessary to start the electric slide rail 205b to make the slide block 205c rotate counterclockwise (looking down at the direction of the laser welding gun 101, the same below). When the slide block 205c rotates counterclockwise, the U-shaped seat 205d rotates counterclockwise around the ring 205a. At this time, the slide bar 204 The first gear 202b rotates clockwise when the first gear 202c moves downward. The rotating shaft 201b rotates clockwise (from the direction facing the first gear 202b, the same below), and then the first gear 202c rotates clockwise when the first gear 202c moves downward. The protective lens 104 is driven to leave the launch area 102. When the slide bar 204e moves into the first arc groove 204a, the protective lens 104 is completely separated from the launch area 102. As the U-shaped seat 205d continues to move, the slide bar 204e moves to the right end of the first arc groove 204a. At this time, the L-shaped strip 205e moves to the adjacent arc plate 203b. When the slide bar 204e moves in the second arc groove 204b, it drives the L-shaped strip 205e corresponding to the substitute lens 201f to move upward, thereby This drives the L-shaped plate 203a to move upward, drives the first tooth plate 202c to move upward, and thus the first gear 202b rotates counterclockwise, drives the rotating shaft 201b to rotate, causes the inclined plate 201c to rotate, and drives the carrying ring 201e to move to the lower side of the launch area 102, so that the replacement lens 201f replaces the protective lens 104 and plays a protective role again. Similarly, when the replacement lens 201f is damaged next time, the same operation can be performed again to replace the replacement lens 201f, thereby achieving the effect of automatic replacement.
[0033] In summary, by setting the welding component 100 and the replacement component 200, when the protective lens 104 on the laser welding gun 101 is damaged, it is only necessary to start the electric slide rail 205b to remove the protective lens 104 and turn the new replacement lens 201f to the lower side of the emission area 102. No manual replacement is required, and it is convenient and efficient to use.
[0034] Example 2, reference Figure 1 to Figure 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a protective component 300 of a new energy vehicle frame laser welding device, which solves the problem of how to protect multiple substitute lenses 201f when the substitute lenses 201f are not in use. It includes a shielding component 301, including a disk 301a fixedly connected to the side wall of the laser welding gun 101, and the disk 301a is provided with a plurality of strip-shaped openings for the first tooth plate 202c to pass through. The disk 301a is provided with an opening 301b, and multiple substitute lenses 201f are all in the opening 301b. A transmission shaft 301c is rotatably connected to the inner wall of the opening 301b, and dustproof plates 301d matching the substitute lenses 201f are fixedly connected to the multiple transmission shafts 301c; the pushing component 302 includes a plurality of mounting grooves 302a arranged in the wall of the disk 301a, and the plurality of Each mounting groove 302a is sealed and slidably connected with a sliding plug 302b, and a second tooth plate 302c is fixedly connected to the sliding plug 302b. An extension shaft 302d is rotatably connected in the mounting groove 302a, and the extension shaft 302d passes through the disc 301a and is fixedly connected to the transmission shaft 301c. A gear meshing with the second tooth plate 302c is fixedly connected to the extension shaft 302d; the pump air component 303 includes an arc groove 303a arranged on the L-shaped plate 203a, and an arc block 303b is sealed and slidably connected in the arc groove 303a. A cutout 303c is provided on the arc block 303b, and the arc block 303b is elastically connected to the inner wall of the arc groove 303a through a second spring 303d. The arc groove 303a is sealed and connected to the mounting groove 302a through an air guide pipe 303e, and the sliding plug 302b is elastically connected to the inner wall of the mounting groove 302a through a third spring.
[0035] Specifically, the amount of gas in the arc groove 303a is sufficient to ensure that the sliding plug 302b can be pushed to move. When the transmission shaft 301c rotates, it is only necessary to misalign the dustproof plate 301d with the load-bearing ring 201e. There is no need to rotate a large angle, and the dustproof plate 301d will not collide with the inner wall of the opening 301b. The conduit here passes through the outer end of the arc block 303b and enters the mounting groove 302a from the upper end of the disc 301a. The length of the air guide tube 303e is sufficient. When the arc plate 203b moves up and down, the arc plate 203b will not get stuck. The elasticity of the first spring 203c is greater than the elasticity of the second spring 303d, so that when the L-shaped bar 205e contacts the arc block, it can push the arc block upward instead of pushing the entire arc plate 203b upward.
[0036] When in use, the substitute lens 201f is blocked by the dustproof plate 301d. During the welding process, even if there is slag or flying particles, they will not hit the substitute lens 201f, avoiding damage to the substitute lens 201f. At the same time, the substitute lens 201f is between the dustproof plate 301d and the inner wall of the opening 301b, achieving a dustproof effect. In the process of the L-shaped bar 205e and the arc block 303b abutting against each other (that is, the slide bar 204e slides in the first arc groove 204a), the L-shaped bar 205e first cooperates with the incision 303c. As the L-shaped bar 205e continues to move, it can push the arc block 303b to move toward the arc groove 303a. At this time, the gas in the arc groove 303a can be passed through The air is pumped into the installation groove 302a through the air guide pipe 303e, so that the slide plug 302b moves and drives the second tooth plate 302c to move, thereby causing the second gear 302e to rotate, so that the dustproof plate 301d and the substitute lens 201f are misaligned. Therefore, when the slide rod 204e moves into the second arc groove 204b, the replacement lens 201f will not collide with the dustproof plate 301d when the inclined plate 201c is deflected through the transmission. When the slide rod 204e moves in the third arc groove 204c and the fourth arc groove 204d, since the arc block 303b has not been reset, the dustproof plate 301d and the substitute lens 201f will not collide when the inclined plate 201c is reset.
[0037] In summary, by setting up a dust-proof component, when the substitute lens 201f is not in use, the substitute lens 201f is located between the dust-proof plate 301d and the inner wall of the opening 301b, thereby protecting the substitute lens 201f. When the substitute lens 201f is in use, the dust-proof plate 301d will automatically move away and will not block the use of the substitute lens 201f.
[0038] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an opening component 304 of a laser welding device for a new energy vehicle frame, which solves the problem of how to replace multiple substitute lenses 201f when multiple substitute lenses 201f are damaged. It includes an opening component 304, including multiple fan-shaped openings 304a arranged on a disk 301a, and fan-shaped plates 304b are arranged in the multiple fan-shaped openings 304a. Specifically, the multiple fan-shaped openings 304a are located directly above the replacement lens 201f, so as to facilitate the replacement of the replacement lens 201f. In this embodiment, the horizontal plate 201d and the supporting ring 201e are arranged to be detachably connected, such as bolt connection, bayonet connection, etc. The method is not limited here, and any method that can meet the reset requirements is acceptable.
[0039] During use, when multiple replacement lenses 201f are damaged, it is only necessary to open the fan-shaped plate 304b. A lock can be set on the fan-shaped plate 304b to ensure that the fan-shaped plate 304b will not separate from the fan-shaped opening 304a when the laser welding gun 101 is inverted. When the fan-shaped plate 304b is opened, the replacement lens 201f can be replaced directly by hand.
[0040] In summary, by providing the opening component 304 , the upper end of the disc 301a can be opened, so that the replacement lens 201f can be exposed to the outside, so as to facilitate the replacement of the replacement lens 201f and ensure the integrity of the replacement lens 201f when it is transferred to the lower side of the emission area 102 .
[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
