[0044] See also Figure 1An embodiment of the present invention provides a replacement device 100 for replacing the protective mirror 210 of a laser welding gun 200, comprising a housing 10, a dust removal structure 20, and a replacement assembly 30. The housing 10 is provided with a receiving chamber 11 and an opening 13, the opening 13 being in communication with the receiving chamber 11, and the opening 13 being used for allowing the laser welding gun 200 to extend into the receiving chamber 11. The dust removal structure 20 is in communication with the receiving chamber 11 to remove dust from the receiving chamber 11. The replacement assembly 30 is disposed in the receiving chamber 11, and the replacement assembly 30 can move in a vertical direction to disassemble the protective mirror 210 of the laser welding gun 200 in a vertically downward direction. The replacement assembly 30 can also move in a vertical direction to install the protective mirror 210 of the laser welding gun 200 in a vertically upward direction.

[0045] In an embodiment of the present utility model, the replacement component 30 can replace the protective mirror 210 of the laser welding gun 200, realizing the automation of replacing the protective mirror 210, and the dust removal structure 20 can remove dust from the accommodating chamber 11, reducing the probability of dust falling into the laser welding gun 200 during the replacement process. In addition, since the replacement component 30 vertically removes the protective mirror 210 downward and installs the protective mirror 210 vertically upward, the opening of the laser welding gun 200 for replacing the protective mirror 210 is facing downward, reducing the dust in the accommodating chamber 11 from falling into the laser welding gun 200 along the opening of the laser welding gun 200 for replacing the protective mirror 210 under the action of gravity, thereby achieving a better replacement effect.

[0046] Specifically, the box body 10 can be in the shape of a cuboid, a cylinder, etc., and this application does not impose any specific restrictions. The accommodating chamber 11 remains in a relatively dust-free state under the dust removal of the dust removal structure 20, so that the protective mirror 210 of the laser welding gun 200 can be replaced in a relatively dust-free environment by the replacement component 30. The opening 13 is used for the laser welding gun 200 to extend into the accommodating chamber 11, so that the replacement component 30 in the accommodating chamber 11 can replace the protective mirror 210. It can be understood that the replacement device 100 can also be provided with a fixing part, which is arranged in the accommodating chamber 11. After the laser welding gun 200 is extended into the accommodating chamber 11, the fixing part limits the laser welding gun 200, so that the replacement component 30 can replace the protective mirror 210 of the laser welding gun 200. It can be understood that there are many structures of the fixing part. The fixing part may include a clamping claw, so that after the laser welding gun 200 is extended into the accommodating cavity 11, the clamping claw clamps the accommodating cavity 11; the fixing part may include an elastic part, the elastic part is provided with a welding gun through hole, the laser welding gun 200 is inserted into the welding gun through hole to cause the elastic part to produce elastic deformation to limit the laser welding gun 200; the fixing part may include a supporting part, the supporting part is provided with a limiting groove and a replacement opening, the limiting groove is used to accommodate the laser welding gun 200, the replacement opening is connected to the limiting groove, and the replacement component 30 replaces the protective mirror 210 of the laser welding gun 200 through the replacement opening.

[0047] The dust removal structure 20 is used to remove dust from the accommodating chamber 11. The dust removal structure 20 can remove dust in many ways. The dust removal structure 20 can perform negative pressure dust removal on the accommodating chamber 11 to suck the dust out of the accommodating chamber 11; the dust removal structure 20 can blow air into the accommodating chamber 11 to blow the dust out of the accommodating chamber 11; the dust removal structure 20 can also blow air into the accommodating chamber 11 on one side and pump air into the accommodating chamber 11 on the other side to promptly discharge the dust in the accommodating chamber 11. In one embodiment, the dust removal structure 20 guides the dust in the accommodating chamber 11 to move in a vertically downward direction. In this way, the dust can move downward under the drive of the dust removal structure 20 and the action of gravity, preventing dust from falling into the laser welding gun 200 during the replacement of the protective mirror 210.

[0048] The replacement component 30 is used to replace the protective mirror 210 of the laser welding gun 200. It is understandable that there are many ways to replace the protective mirror 210 of the laser welding gun 200 with the replacement component 30. For example, in the case where the protective mirror 210 is limited by magnetic adsorption, the replacement component 30 clamps the protective mirror 210 and pulls out or pushes the protective mirror 210 to achieve the removal or installation of the protective mirror 210. At this time, the replacement component 30 may include structures such as clamping claws and negative pressure adsorption parts. For another example, in the case where the protective mirror 210 is limited by bolts, the replacement component 30 may include a screwdriver part for removing the bolts and a clamping claw for clamping the protective mirror 210, a negative pressure adsorption part, etc., which are not listed one by one in this application.

[0049] See also Figure 1 In an embodiment of the present invention, the replacement assembly 30 includes a disassembly component 31 and a mounting component 33. The disassembly component 31 can move in a vertical direction to disassemble the protective mirror 210 of the laser welding gun 200 in a vertical downward direction, and the mounting component 33 can move in a vertical direction to install the protective mirror 210 of the laser welding gun 200 in a vertical upward direction.

[0050] In this way, the protective mirror can be replaced by the replacement component 30.

[0051] It is understandable that there are many ways for the disassembly member 31 to move in the vertical direction, and the disassembly member 31 may include a drive member such as a cylinder or a motor, and this application does not impose specific restrictions. There are many ways for the installation member 33 to move in the vertical direction, and the installation member 33 may include a drive member such as a cylinder or a motor.

[0052] It is worth noting that the disassembly part 31 and the installation part 33 can be a structure, that is, the same structure first disassembles the old protective mirror 210, puts down the old protective mirror 210, and then takes the new protective mirror 210 to replace it on the laser welding gun 200. The replacement component 30 can replace the protective mirror 210, and this application does not make specific restrictions.

[0053] See also Figure 1In the embodiment of the present invention, the replacement component 30 further includes a rotating seat 35 , which is connected to the box body 10 , the disassembly member 31 is rotatably connected to the rotating seat 35 , and the installation member 33 is rotatably connected to the rotating seat 35 .

[0054] In this way, the disassembly member 31 and the installation member 33 can rotate relative to the rotating seat 35, making it convenient for the disassembly member 31 to place the disassembled protective mirror 210 and also convenient for the installation member 33 to take the protective mirror 210 to be replaced.

[0055] For further information, see Figure 1 The rotating seat 35 includes a rotating shaft 351, and the replacement component 30 also includes a rotating member (not shown). The rotating member is sleeved on the rotating shaft 351. The disassembly member 31 and the mounting member 33 are fixedly connected to the rotating member. The disassembly member 31 and the mounting member 33 are respectively arranged at intervals along the circumferential direction of the rotating member, so that the mounting member 33 and the disassembly member 31 can be rotatably connected to the rotating seat 35 through the rotating member.

[0056] In this way, since the disassembly part 31 and the installation part 33 are arranged at intervals along the circumferential direction of the rotating part, the disassembly part 31 and the installation part 33 are located at the same axial position of the rotating shaft 351, that is, the disassembly part 31 and the installation part 33 can be rotated to the same position respectively, ensuring that the disassembly part 31 and the installation part 33 can accurately align the laser welding gun 200.

[0057] Specifically, if the disassembly part 31 and the mounting part 33 are located at different axial positions of the rotating shaft 351, then when the disassembly part 31 and the mounting part 33 are rotated to the vertically upward position, the positions of the disassembly part 31 and the mounting part 33 will be different, which makes it impossible for both the disassembly part 31 and the mounting part 33 to be aligned with the laser welding gun 200. During the process of replacing the protective mirror 210 after disassembly, the position of the mounting part 33 can be adjusted or the position of the laser welding gun 200 needs to be adjusted to ensure alignment.

[0058] It is worth noting that there are many ways for the mounting member 33 to be rotatably connected to the rotating seat 35. Alternatively, the rotating seat 35 may be provided with a rotating groove, and the mounting member 33 may be provided with a rotating protrusion, which cooperates with the rotating groove. The same is true for the disassembly member 31, which will not be described in detail.

[0059] See also Figure 1 In an embodiment of the present invention, the replacement device 100 further includes a first storage component 41 and a second storage component 43. The first storage component 41 and the second storage component 43 are both arranged in the accommodating cavity 11. The first storage component 41 is for the installation component 33 to take the protective mirror 210, and the second storage component 43 is for the disassembly component 31 to place the protective mirror 210.

[0060] In this way, the replacement device 100 can replace more laser welding guns 200, effectively improving the replacement efficiency.

[0061] It can be understood that during the process of the disassembly part 31 disassembling the protective mirror 210, the installation part 33 can take the protective mirror 210 from the first storage part 41, effectively utilizing the time of the disassembly part 31 disassembling the protective mirror 210, and improving the replacement efficiency. Similarly, during the process of the installation part 33 installing the protective mirror 210, the disassembly part 31 can place the protective mirror 210 into the second storage part 43, so as to utilize the time of the installation part 33 installing the protective mirror 210, and further improve the replacement efficiency.

[0062] See also Figure 1 In the embodiment of the present invention, the disassembly member 31 includes a first clamping jaw 311 for clamping the protective mirror 210 , and the installation member 33 includes a second clamping jaw 331 for clamping the protective mirror 210 .

[0063] In this way, the disassembly member 31 can clamp the protective mirror 210 through the first clamping jaw 311 , and the installation member 33 can clamp the protective mirror 210 through the second clamping jaw 331 , so as to achieve replacement of the protective mirror 210 .

[0064] Furthermore, the disassembly part 31 also includes a first sensing part (not shown), which is used to sense with the laser welding gun 200 to release the limitation of the protective mirror 210. The installation part 33 also includes a second sensing part (not shown), which is used to sense with the laser welding gun 200 to achieve the limitation of the protective mirror 210.

[0065] In this way, it can sense the laser welding gun 200 equipped with a corresponding sensor to release the laser welding gun 200 from limiting the protective mirror 210 or to achieve the laser welding gun 200 limiting the protective mirror 210, so as to facilitate the replacement of the protective mirror 210 by the replacement component 30.

[0066] It can be understood that the first sensing part and the second sensing part may include magnetic strips, radio frequency structures, etc. The first sensing part and the second sensing part can sense the laser welding gun 200 so that the laser welding gun 200 releases or opens the limit on the protective mirror 210. This application does not impose any specific restrictions.

[0067] See also Figure 1 In an embodiment of the present invention, the replacement device 100 further includes a dust detector 50 , which is used to detect dust in the accommodating chamber 11 .

[0068] In this way, the situation where the dust exceeds the standard can be discovered in time, and the life of the laser welding gun 200 is avoided from being shortened due to replacement of the protective mirror 210 when the dust exceeds the standard.

[0069] Specifically, the dust detector 50 may include a laser dust detector, a light scattering dust detector, etc., and this application does not impose any specific restrictions.

[0070] It is understandable that the replacement device 100 may further include a device switch 60 , so as to facilitate the control of the operation or shutdown of the replacement device 100 .

[0071] Figures 1 to 3 The embodiment of the present invention further provides a welding gun protective mirror replacement system 500, wherein the laser welding gun 200 includes a laser welding gun 200 and a replacement device 100, the laser welding gun 200 includes a protective mirror 210, the laser welding gun 200 extends into the accommodating cavity 11 through the opening 13, and the replacement component 30 replaces the protective mirror 210 through the protective opening 233 in the vertical direction. The specific structure of the replacement device 100 refers to the above embodiment. Since the laser welding gun 200 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments.

[0072] In an embodiment of the present utility model, the replacement component 30 can replace the protective mirror 210 of the laser welding gun 200, realizing the automation of replacing the protective mirror 210, and the dust removal structure 20 can remove dust from the accommodating chamber 11, reducing the probability of dust falling into the laser welding gun 200 during the replacement process. In addition, since the replacement component 30 vertically removes the protective mirror 210 downward and installs the protective mirror 210 vertically upward, the opening of the laser welding gun 200 for replacing the protective mirror 210 is facing downward, reducing the dust in the accommodating chamber 11 from falling into the laser welding gun 200 along the opening of the laser welding gun 200 for replacing the protective mirror 210 under the action of gravity, thereby achieving a better replacement effect.

[0073] See also Figure 2 In an embodiment of the present invention, the laser welding gun 200 further includes: a body 230, the body 230 is provided with a protective cavity 231 and a protective opening 233, the protective opening 233 is communicated with the protective cavity 231, and the protective opening 233 is used for the protective mirror 210 to enter or leave the protective cavity 231; a limiting member 250, the limiting member 250 limits the protective mirror 210 to keep the protective mirror 210 located in the protective cavity 231.

[0074] In this way, the limiting member 250 can limit the protective mirror 210 to prevent the protective mirror 210 from being separated from the protective cavity 231 without the action of external force.

[0075] It is understandable that the limiting member 250 may include a bolt, a latch, a magnetic member, etc., and this application does not impose any specific limitation.

[0076] For further information, see Figure 2 The protective mirror 210 is provided with a plug-in through hole (not shown), the axial direction of the plug-in through hole is perpendicular to the opening direction of the protective opening 233, the limiter 250 can be plugged into and matched with the plug-in through hole, and the laser welding gun 200 is also provided with a third sensing part 270, which controls the limiter 250 to move in a direction close to or away from the plug-in through hole.

[0077] In this way, the third sensing part 270 can sense with the first sensing part and with the second sensing part. Under the action of the first sensing part, the third sensing part 270 can move in the direction away from the plug-in hole to release the limitation on the protective mirror 210. The third sensing part 270 can move in the direction close to the plug-in hole under the action of the second sensing part to achieve the limitation on the protective mirror 210.

[0078] It is understandable that the laser welding gun 200 may further include a limit driving component, which may include a motor, a cylinder, and other structures. The limit driving component is driven to move by the third sensing part 270 to drive the limit driving component 250 to move.

[0079] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
