DETAILED DESCRIPTION

[0022] 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.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0024] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0026] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0027] Please combine Figure 1 The handheld laser welding gun provided by the present invention is now described. The handheld laser welding gun comprises a body 1, a closure 2, a driving module 3 and a window 4. The body 1 is provided with a containing space 11 and a light emitting channel 12. The light emitting channel 12 connects the containing space 11 and the external space. The window 4 is arranged in the containing space 11 so that the light beam penetrating the window 4 can be emitted to the external space through the light emitting channel 12. The driving module 3 is arranged in the body 1 and connected to the closure 2. The driving module 3 can drive the closure 2 to move so as to open or block the light emitting channel 12.

[0028] It can be understood that the light output channel 12 connects the accommodating space 11 and the external space, and the window 4 is arranged in the accommodating space 11 so that the light beam penetrating the window 4 can be emitted to the external space through the light output channel 12. Since there will be more dust and splashes in the light output channel 12, after the welding gun is not in use, the dust and splashes can enter the accommodating space 11 from the light output channel 12, and then contaminate the window 4. The driving module 3 is connected to the closure 2 and drives the closure 2 to move, so that the light output channel 12 can be turned on or off. After blocking the light output channel 12, dust and splashes can be prevented from contaminating the window 4, thereby ensuring the light transmittance of the window 4. There is no need to remove the window 4 for cleaning or replace it with a new window 4, which reduces the user's work difficulty and improves work efficiency.

[0029] In one embodiment, continue as Figure 1As shown, the light outlet channel 12 includes a light inlet 121 and a light outlet 122 that are relatively arranged. The light inlet 121 is connected to the accommodating space 11. The closure member 2 is arranged in the accommodating space 11. The driving module 3 can drive the closure member 2 to rotate to expose or cover the light inlet 121.

[0030] It is understandable that when the handheld laser welding gun is working, the driving module 3 drives the closure 2 to rotate to expose the light inlet 121, so that the laser of the handheld laser welding gun can enter the light inlet 121 and then be emitted through the light outlet 122. When the handheld laser welding gun is not in use, the driving module 3 drives the closure 2 to rotate to block the light inlet 121, so as to prevent dust and splashes in the light outlet 122 from entering the light inlet 121, thereby preventing the window 4 in the accommodating space 11 from being contaminated.

[0031] In this embodiment, the window sheet 4 is arranged in the accommodating space 11 at a side away from the light inlet 121, so that when the driving module 3 drives the sealing member 2 to rotate, sufficient avoidance space can be reserved in the accommodating space 11 to prevent the sealing member 2 from rotating and damaging the window sheet 4. In addition, the window sheet 4 is kept at a certain distance from the light inlet 121, which can better reduce the pollution of dust or splashing objects.

[0032] In one embodiment, if Figure 2 and Figure 3 As shown, the driving module 3 includes a transmission mechanism 31 and a manual member 32. The transmission mechanism 31 is disposed in the accommodating space 11, and the manual member 32 is at least partially exposed outside the body 1. The transmission mechanism 31 is connected to the manual member 32 and the closing member 2. The manual member 32 can be operated to control the closing member 2 to expose or cover the light inlet 121 through the transmission mechanism 31. Specifically, the staff operates the manual member 32, and the manual member 32 can drive the closing member 2 to rotate through the transmission mechanism 31, so that the closing member 2 can expose or cover the light inlet 121, making the operation of the staff convenient and simple.

[0033] In this embodiment, the transmission mechanism 31 includes a gear 311 and a rack 312. The gear 311 is rotatably connected to the inner wall of the accommodating space 11 and is connected to the end of the closure member 2 so that the closure member 2 can rotate relative to the inner wall of the accommodating space 11. The gear 311 is meshed with the rack 312, and the manual member 32 is movably connected with the rack 312. The manual member 32 can be operated to drive the rack 312 to move in the first direction to drive the gear 311 to rotate and expose the light inlet 121. Specifically, the staff operates the manual member 32, and the manual member 32 drives the rack 312 to move in the first direction. The rack 312 is meshed with the gear 311, so that the rack 312 can drive the gear 311 to rotate, so that the gear 311 can drive the closure member 2 to rotate, and the closure member 2 exposes the light inlet 121.

[0034] Of course, in other embodiments, a slide groove is provided on the inner wall of the accommodating space 11, and the rack 312 is slidably connected to the groove wall of the slide groove. By operating the manual member 32, the manual member 32 can drive the rack 312 to slide along the slide groove, thereby moving along the first direction.

[0035] In one embodiment, a guide rail is provided in the inner wall of the accommodating space 11, and the rack 312 is provided with a guide groove adapted to the guide rail. The guide rail is slidably connected to the groove wall of the guide groove. By operating the manual member 32, the manual member 32 can drive the rack 312 to slide along the guide rail, thereby moving along the first direction.

[0036] It should be noted that, depending on the placement of the handheld welding laser gun, the first direction may be a vertical direction or a horizontal direction. For ease of understanding, in the relevant embodiments, the first direction is a horizontal direction.

[0037] Furthermore, the transmission mechanism 31 also includes a first elastic member 313, which elastically connects the rack 312 and the inner wall of the accommodating space 11. In a free state, the first elastic member 313 can push the rack 312 to move along the second direction to drive the gear 311 to rotate and block the light entrance 121. The first direction is opposite to the second direction.

[0038] Specifically, the first elastic member 313 can be a spring or an elastic member. The staff operates the manual member 32, and the manual member 32 drives the rack 312 to move along the first direction. The rack 312 is meshed with the gear 311, so that the rack 312 can drive the gear 311 to rotate, so that the gear 311 can drive the sealing member 2 to rotate, and the sealing member 2 exposes the light inlet 121. At this time, the first elastic member 313 is in a compressed state.

[0039] The staff releases the manual part 32, and the first elastic part 313 returns to a free state, so that the first elastic part 313 can push the rack 312 to move along the second direction, and the rack 312 engages with the gear 311, so that the rack 312 can drive the gear 311 to rotate, so that the gear 311 can drive the closure part 2 to rotate, and the closure part 2 blocks the light inlet 121.

[0040] In one embodiment, continue as Figure 2 and Figure 3 As shown, the rack 312 includes a tooth portion 3121 and a driving portion 3122 connected to the tooth portion 3121, the tooth portion 3121 is meshed with the gear 311, the manual member 32 includes a traction portion 321 and a trigger portion 322 connected to the traction portion 321, the trigger portion 322 is exposed outside the main body 1, the traction portion 321 is provided with a traction groove 3211, and the driving portion 3122 is provided with a protruding structure 3123 slidably connected to the groove wall of the traction groove 3211.

[0041] Specifically, the protruding structure 3123 can be a slide rail, which is slidably connected to the groove wall of the traction groove 3211. The protruding structure 3123 can also be a slide rod, which is slidably connected to the groove wall of the traction groove 3211. The staff pulls the trigger part 322, and the trigger part 322 drives the traction part 321 to move, so that the protruding structure 3123 can slide in the traction groove 3211 of the traction part 321, so that the traction part 321 can drive the protruding structure 3123 to move along the first direction, and the protruding structure 3123 drives the driving part 3122 to move along the first direction, so that the driving part 3122 drives the tooth part 3121 to move along the first direction, and the tooth part 3121 is engaged with the gear 311 to drive the gear 311 to rotate, and the gear 311 drives the closure 2 to rotate to expose the light inlet 121. The operation mode of pulling the trigger part 322 to rotate the closure 2 to expose the light inlet 121 is simple to operate and convenient to use.

[0042] In this embodiment, the handheld laser welding gun further includes a laser device (not shown in the figure) and a switch 5. The switch 5 is arranged on the body 1 and is arranged opposite to the trigger part 322. The laser device is arranged on the body 1 and is electrically connected to the switch 5. Pressing the trigger part 322 can drive the switch 5 to perform a switching action to control the operation and stop of the laser device. Specifically, the trigger part 322 is arranged opposite to the switch 5. When the trigger part 322 is pulled, the trigger part 322 drives the closure 2 to rotate so that the closure 2 exposes the light inlet 121. At the same time, the trigger part 322 drives the switch 5 to perform a switching action, so that the laser device starts to work. The laser device emits laser light through the high-value optical element and the window 4, and then emits it through the light inlet 121. The trigger part 322 drives the closure 2 to rotate to expose the light inlet 121 and the trigger part 322 drives the switch 5 to perform a switching action synchronously, so that the laser emitted by the laser device can be smoothly emitted from the light inlet 121.

[0043] Further, the transmission mechanism 31 also includes a second elastic member (not shown in the figure), the second elastic member elastically connects the traction part 321 and the inner wall of the accommodating space 11, and in a free state, the second elastic member can push the traction part 321 to reset, so as to drive the trigger part 322 to reset. Specifically, the second elastic member can be a spring, or a component with elasticity. The trigger part 322 is connected to the switch part 5, and the trigger part 322 is pulled, and the trigger part 322 drives the closure part 2 to rotate, so that the closure part 2 exposes the light inlet 121. At the same time, the trigger part 322 drives the switch part 5 to perform a switching action, and the switch part 5 controls the operation of the laser device. At this time, the second elastic member is in a compressed state. When the trigger part 322 is released, the second elastic member is in a free state, and the second elastic member can push the traction part 321 to reset, so that the trigger part 322 and the switch part 5 are reset and closed, so that the closure part 2 blocks the light inlet 121, and the switch part 5 controls the operation of the laser device to stop.

[0044] Of course, in other embodiments, the trigger part 322 abuts against the switch member 5, and the switch member 5 includes a free end, a fixed end, and a third elastic member. The free end can move relative to the fixed end, and the third elastic member is disposed between the free end and the fixed end. In the free state, the third elastic member can push the free end to reset so that the switch member 5 is closed. Specifically, the third elastic member can be a spring or an elastic component. When the trigger part 322 is pulled, the trigger part 322 drives the closure member 2 to rotate so that the closure member 2 exposes the light inlet 121. At the same time, the trigger part 322 drives the free end to move, the second elastic member is in a compressed state, and the third elastic member between the free end and the fixed end is in a compressed state. The switch member 5 performs a switching action, and the switch member 5 controls the operation of the laser device. When the trigger part 322 is released, the second elastic member and the third elastic member are in a free state. The second elastic member can push the traction part 321 to reset, so that the trigger part 322 is reset, so that the closing member 2 blocks the light entrance 121, and the third elastic member can push the free end to reset, so that the switch member 5 is closed, so that the switch member 5 controls the laser device to stop working.

[0045] It should be noted that, in the relevant embodiment, the manual member 32 is rotatably connected to the main body 1. When the manual member 32 is pressed, the manual member 32 rotates relative to the main body 1, so that the closing member 2 can expose or block the light entrance 121, and control the switch member 5 to perform the switching action, which is convenient for the staff to use.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
