Description
Technical Field
The utility model relates to a welding equipment technical field, in particular to handheld laser welder head with safety device.
Background
In laser welding, high-energy laser pulses are used for locally heating materials in micro-areas, energy radiated by laser is diffused into the materials through heat conduction, and the materials are melted to form a specific molten pool.
At present, the handheld laser welding technology is widely used due to the advantages of flexible and convenient use, simple operation, high power and the like, and the welding power is generally over 500W. The working principle is as follows: the board card passes through electrode holder connecting plate, and the laser instrument is connected to the integrated circuit board simultaneously, connects panel through the copper nozzle on the laser welding head to form the return circuit, realize the welding effect.
However, in the actual operation process, many workers often directly connect the electrode clamp to the laser welding head for convenience in use, do not need to contact the plate, and can directly weld only by pressing the light outlet switch of the laser welding head, so that the work is facilitated, but a great risk exists at the same time, and inestimable damage is easily caused to people, products, equipment and the like around.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defect of the prior art, the utility model provides a handheld laser welder head with safety device through set up proximity switch on laser welder head, makes laser welder head be close panel to certain within range could work, effectively reduces this risk of having eliminated even.
The technical scheme for realizing the purpose is as follows:
the utility model provides a handheld laser welder head with safety device, control integrated circuit board and laser instrument including signal connection, integrated circuit board still electricity is connected with the electrode holder that is used for a centre gripping panel that waits to weld, the laser instrument is connected with the laser welder head, and the top of laser welder head is equipped with the copper nozzle, a proximity switch is still connected to the integrated circuit board electricity, proximity switch is fixed in on the laser welder head, wherein, proximity switch's top with distance between the top of copper nozzle is greater than 0, and is less than 1.5mm, and when carrying out weldment work, the panel that welds is treated in the contact of copper nozzle, and makes panel when within proximity switch's response scope simultaneously, can carry out the light-emitting welding.
Furthermore, the proximity switch is detachably connected with the laser welding head, so that the proximity switch and the laser welding head can be conveniently maintained, repaired or replaced separately, and the cost is saved.
Further, the laser welding headgear is equipped with a metal clamp, metal clamp still an organic whole be connected with the parallel second through-hole of laser welder head, proximity switch is fixed in the second through-hole, just proximity switch's top is close to the copper nozzle to make overall structure compacter, the welding operation of being convenient for simultaneously.
Has the advantages that: compared with the prior art, the utility model discloses a difference lies in, the utility model provides a handheld laser welder head with safety device, including the control integrated circuit board, the laser instrument, the laser welder head, electrode holder and proximity switch, laser welder head's top is equipped with the welding copper nozzle, laser instrument and laser welder head are connected to the integrated circuit board electricity, its other end connection electrode holder, the laser welder head is connected with the electrode holder and is constituted the return circuit and realize the welding, the overhead proximity switch who still is provided with the control light-emitting of laser welder, no matter the electrode holder is connected on panel, still connect on the laser welder head, only proximity switch is close to welding panel to certain within range, two signals switch-on simultaneously just can carry out weldment work, thereby the security performance of handheld laser welder head has been improved, the risk of workman maloperation has been.
Drawings
FIG. 1 is a front view of a hand-held laser welding head with a safety device according to a preferred embodiment of the present application.
The device comprises a laser welding head 1, a copper nozzle 11, a proximity switch 2 and a metal hoop 3.
Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
Referring to fig. 1, the utility model provides a hand-held laser welding head with a safety device, which comprises a control board card and a laser connected by electric signals, the board card is also electrically connected with an electrode clamp used for clamping a plate to be welded, the laser is connected with a laser welding head 1, the top end of the laser welding head 1 is provided with a copper nozzle 11, the copper nozzle 11 or the laser welding head 1 is connected with the electrode clamp to form a loop, the board card is also electrically connected with a proximity switch 2, the proximity switch 2 is fixed on the laser welding head 1, wherein the distance between the top end of the proximity switch 2 and the top end of the copper nozzle 11 is 1mm, when the welding work is carried out, the copper nozzle 11 contacts the plate to be welded, the plate is only 1mm away from the proximity switch 2, within the sensing range of the proximity switch 2, the proximity switch 2 is triggered, and the two signals are simultaneously switched on to normally work. Therefore, no matter the electrode holder centre gripping is on panel, still with the electrode holder centre gripping on laser welder head 1, only proximity switch 2 is close panel to certain distance scope, and the integrated circuit board just can the light-emitting carry out normal weldment work after receiving two signals simultaneously to the maloperation risk of handheld laser welding work has effectively been reduced.
Preferably, considering that both the proximity switch 2 and the laser welding head 1 are damaged or have exhausted service life and the like, the proximity switch 2 and the laser welding head 1 are detachably connected, and in the later period, the maintenance, the repair or the replacement of the proximity switch 2 or the laser welding head 1 can be independently processed and installed again for use after corresponding processing, so that the resources are saved and the cost is reduced.
Preferably, laser welder head 1 cover is equipped with metal clamp 3, metal clamp 3 still an organic whole be connected with the parallel second through-hole of laser welder head 1, proximity switch 2 is fixed in the second through-hole, just proximity switch 2's top is close to copper nozzle 11 for make overall structure compacter, pleasing to the eye, the welding operation of being convenient for simultaneously.
The above embodiments are merely preferred embodiments of the present disclosure, which are not intended to limit the present disclosure, and any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present disclosure, should be included in the scope of the present disclosure.
