[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the equipment or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] This application provides a laser welding device, such as... Figure 1 As shown, the laser welder 10 includes a welding torch 110, a motor 120, and a mounting assembly 200 for the motor 120. The motor 120 is mounted on the welding torch 110 via the mounting assembly 200, and the drive end of the motor 120 can extend into the interior of the welding torch 110 to connect with the internal reflector 130, thereby driving the reflector 130 to move. Therefore, in this embodiment, the motor 120 is a galvanometer motor 120.

[0035] Please also refer to Figures 1 to 4 The mounting assembly 200 includes a mounting base 210 and a connecting sleeve 220. The mounting base 210 is connected to the welding gun 110, specifically by bolts. The mounting base 210 has a through mounting hole 211, which includes a first connecting section 212 and a first adjusting section 213 arranged sequentially along its axial direction. The inner wall of the first connecting section 212 has a spherical recess 214.

[0036] A connecting sleeve 220 is disposed on the outside of the motor 120 and within the mounting hole 211 to mount the motor 120 onto the mounting base 210. The connecting sleeve 220 includes a second connecting section 221 and a second adjusting section 222 arranged sequentially along its length. The outer wall of the second connecting section 221 has a spherical protrusion 223, which is embedded in a spherical recess 214. Simultaneously, a gap exists between the outer wall of the second adjusting section 222 and the inner wall of the first adjusting section 213, allowing the connecting sleeve 220 to move relative to the mounting base 210, thus enabling the motor 120 to move relative to the mounting base 210.

[0037] It can be understood that the second connecting section 221 of the connecting sleeve 220 is connected with the first connecting section 212 of the mounting seat 210 through a spherical pair, and there is a gap between the second adjusting section 222 and the inner wall of the first adjusting section 213, so that the connecting sleeve 220 can rotate in any direction around the center of the spherical pair and rotate in the mounting hole 211. At the same time, the connecting sleeve 220 is fixedly connected with the motor 120, so as to realize the movement of the motor 120 relative to the mounting seat 210 along with the connecting sleeve 220. In addition, it should be noted that the cross-sectional shape of the first adjusting section 213 and the second adjusting section 222 is circular, so as to be suitable for the galvanometer motor 120.

[0038] Further, the mounting assembly 200 further comprises an adjusting assembly 230, which is arranged between the mounting seat 210 and the connecting sleeve 220, and is used for adjusting the position of the connecting sleeve 220 relative to the mounting seat 210. In this way, the position of the motor 120 in the connecting sleeve 220 can be adjusted.

[0039] By using the above mounting assembly 200, the mounting seat 210 is arranged on the welding gun 110, the motor 120 is arranged on the mounting seat 210 through the connecting sleeve 220, and the connecting sleeve 220 can adjust the position relative to the mounting seat 210 under the action of the adjusting assembly 230, so that the position of the motor 120 can be adjusted. In this way, the position of the motor 120 can be adjusted through the adjusting assembly 230 after installation, which reduces the machining and installation precision requirements of the components, and further reduces the machining and installation difficulty, improves the machining and installation efficiency, and also reduces the machining cost.

[0040] Please refer to Figure 4 and Figure 5 In one embodiment, the adjusting assembly 230 comprises a plurality of adjusting members, which are arranged on the mounting seat 210 in a circumferential direction and at intervals, and one end of each adjusting member can extend into the first adjusting section 213 and abut against the outer wall of the second adjusting section 222. In this way, the abutment of the adjusting member against the outer wall of the second adjusting section 222 can push the connecting sleeve 220 to move, and the cooperation of the plurality of adjusting members can realize the adjustment of the position of the connecting sleeve 220. Preferably, the adjusting member is threadedly connected with the mounting seat 210, that is, the adjusting member is a top screw, and the plurality of adjusting members are arranged at intervals in the circumferential direction of the mounting seat 210.

[0041] In one embodiment, one end of each adjusting member abuts against one end of the second adjusting section 222 away from the second connecting section 221 to improve the adjusting accuracy. It is to be explained that the connecting sleeve 220 rotates around the center of the spherical pair at the second connecting section 221, and the farther away from the center of the spherical pair, the greater the activity range of the connecting sleeve 220 is when the rotation angle of the connecting sleeve 220 is unchanged. Therefore, by adjusting the position of the end of the connecting sleeve 220 away from the center of the spherical pair, the adjusting accuracy can be effectively improved.

[0042] In one embodiment, the mounting assembly 200 further comprises a fixing assembly 240 arranged between the connecting sleeve 220 and the motor 120 for fixing the connecting sleeve 220 relative to the motor 120. Further, the fixing assembly 240 comprises a plurality of fixing members arranged along the circumference of the connecting sleeve 220 at the second adjusting section 222, and one end of each fixing member can pass through the second adjusting section 222 and abut against the motor 120, so as to fix the connecting sleeve 220 relative to the motor 120. Preferably, the fixing member is a top screw, i.e., the fixing member is also threadedly connected with the second adjusting section 222.

[0043] In one embodiment, the mounting seat 210 and the connecting sleeve 220 are both made of metal to improve the connection strength. Preferably, the mounting seat 210 and the connecting sleeve 220 are both made of stainless steel. Further, a flexible sealing ring 250 is arranged between the mounting seat 210 and the connecting sleeve 220 to ensure the sealing property between them while ensuring that the connecting sleeve 220 can be adjusted in position relative to the mounting seat 210 under the action of the adjusting assembly 230. As an example, a sealing groove 224 is formed in the outer wall of the second adjusting section 222 of the connecting sleeve 220, and the flexible sealing ring 250 is arranged in the sealing groove 224.

[0044] It is to be explained that the adjusting range of the motor 120 is small, i.e., even if the flexible sealing ring 250 is arranged to limit the adjusting range of the motor 120, the motor 120 can still meet the final accuracy requirement after adjustment, and the flexible sealing ring 250 can also improve the sealing property to meet the dustproof requirement. Similarly, a sealing structure, such as a silica gel pad, is arranged between the mounting seat 210 and the welding gun 110 to meet the dustproof requirement.

[0045] In one embodiment, the mounting assembly 200 further comprises an insulating sleeve 260 arranged outside the motor 120, and the connecting sleeve 220 is arranged outside the insulating sleeve 260. As described above, the connecting sleeve 220 is made of metal, and therefore the insulating sleeve 260 is arranged to realize the insulation treatment between the connecting sleeve 220 and the motor 120. Therefore, one end of the above-described fixing member passes through the second adjusting section 222 and abuts against the insulating sleeve 260.

[0046] Further, the mounting assembly 200 further comprises an insulating pad 270, which is arranged on the motor 120 and abuts against the insulating pad 270 at the end of the second adjusting section 222 away from the second connecting section 221, so as to avoid the connecting sleeve 220 directly contacting the motor 120. Preferably, the insulating sleeve 260 and the insulating pad 270 are both made of Teflon material. Of course, the insulating sleeve 260 and the insulating pad 270 can also be made of other insulating materials, such as other plastic materials, which are not limited herein.

[0047] In order to facilitate the understanding of the technical solutions of the present application, the mounting process of the laser welder 10 in the above embodiment is described as follows:

[0048] First, the insulating sleeve 260 and the insulating pad 270 are loaded on the motor 120, the flexible sealing ring 250 is sleeved on the second adjusting section 222 of the connecting sleeve 220, and then the connecting sleeve 220 is installed into the mounting hole 211 of the mounting seat 210, and the spherical protruding part 223 is embedded in the spherical recessed part 214. Next, the connecting sleeve 220 is sleeved on the outside of the insulating sleeve 260, and the connecting sleeve 220, the insulating sleeve 260 and the motor 120 are relatively fixed by the plurality of fixing members. The mirror 130 is mounted on the driving end of the motor 120, and the silica gel pad is attached to the welding gun 110, and then the mounting seat 210 is mounted on the welding gun 110 by using the bolts, at this time, the silica gel pad is located between the welding gun 110 and the mounting seat 210, and the mirror 130 extends into the inside of the welding gun 110. Next, the position of the motor 120 is adjusted by the plurality of adjusting members.

[0049] In summary, the mounting assembly for the motor and the welding laser provided by the present application at least has the following advantages:

[0050] 1. The second connecting section 221 of the connecting sleeve 220 is connected with the first connecting section 212 of the mounting seat 210 through the spherical pair, and there is a gap between the second adjusting section 222 and the inner wall of the first adjusting section 213, so that the position of the motor 120 can be adjusted by the adjusting assembly 230, which reduces the machining and installation precision requirements of the components, thereby reducing the machining and installation difficulty, improving the machining and installation efficiency, and also reducing the machining cost;

[0051] 2. The adjusting member in the adjusting assembly 230 is threadedly connected with the mounting seat 210 and abuts against the end of the second adjusting section 222 away from the second connecting section 221, so as to improve the adjusting precision;

[0052] 3. The mounting seat 210 and the connecting sleeve 220 are both made of metal material, so as to improve the connecting strength, and the insulating sleeve 260 and the insulating pad can realize the insulation between the connecting sleeve 220 and the motor 120;
