Detailed Description
The preferred embodiments described below are by way of example only, and other obvious variations will occur to those skilled in the art. The underlying principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be constructed and operated in a particular orientation and thus are not to be considered limiting.
A laser cladding apparatus according to a preferred embodiment of the present invention will be described in detail below with reference to fig. 1 to 2, wherein the laser cladding apparatus includes a moving device 10 and a laser generating device 20. The exercise apparatus 10 includes an exercise apparatus body 11, at least one start-stop member 12, at least one rotation driving member 13, at least one controller 14, and a movable mounting base 15. The start-stop means 12 and the drive rotation means 13 are provided to the movement device body 11. The start-stop means 12 and the drive rotation means 13 are controllably connected to the controller 14.
The controller 14 includes a control unit 141, at least one start/stop control circuit 142, and at least one rotating part control circuit 143. The control unit 141 includes a start-stop control module 1411 and a rotating member control module 1412. The start-stop control module 1411 and the rotating module part control 1412 of the control unit 141 control the start-stop part 12 and the driving rotating part 13 through the start-stop control circuit 142 and the rotating part control circuit 143, respectively.
The movable mount 15 is movably attached to the exercise apparatus main body 11 via the driving rotation member 13. The laser generator 20 is carried by the movable mount 15 so that the laser generator 20 can move along with the movement of the movable mount 15.
It is understood that when the laser generating device 20 moves along with the movement of the movable mounting seat 15, the laser generating device 20 can be moved to different positions, so that the laser generating device 20 can be aligned to irradiate laser to parts to be processed at different spatial positions. That is, the laser generator 20 is not movable, but only moves along with the movement of the movable mounting seat 15 on the moving device 10.
The controller 14 also includes a laser control circuit 144. The laser control circuit 144 is electrically connected to the control unit 141 and the laser generating device 20.
The control unit 141 further includes a first sub-signal module 1413, wherein the first sub-signal module 1413 is communicatively connected to the laser control circuit 144 and the start-stop control module 1411 to divide the start-stop signal formed by the start-stop control module 1411 into at least two start-stop signals, wherein at least one start-stop signal is transmitted to the start-stop component 12 through the start-stop control circuit 142, and wherein another start-stop signal is transmitted to the laser generating device 20.
In this way, the start and stop of the laser generator 20 can be controlled by the start and stop control module 1411 in the movement device 10. That is, although the laser generator 20 is not provided with a separate control system, since it shares the controller 14 with the motion device 10, the start and stop of the laser generator 20 can be automatically synchronized with the start and stop means 12 of both of the motion devices 10. Thus, the operator does not need to frequently and repeatedly start and stop the laser generator 20 during the actual operation.
As an example, the start-stop means 12 are implemented as a selection from: switch assemblies, cooling pumps, etc. Preferably, the start-stop component 12 is implemented as a cooling pump, and in this case, the start-stop signal corresponds to the cooling pump on/off analog voltage signal, i.e. a 24v voltage signal or a 0v voltage signal.
The control unit 141 further includes a second signal splitting module 1414, wherein the second signal splitting module 1414 is communicably connected to the laser control circuit 144 and the rotating member control module 1412 so as to be capable of splitting the rotating speed analog signal formed by the rotating member control module 1412 into at least two proportional signals, wherein at least one of the proportional signals controls the rotating speed of the driving rotating member 13 through the rotating member control module 1412, and at least another one of the proportional signals controls the output power of the laser generating device 20 through the laser control circuit 144.
It is understood that the rotation speed of the driving rotation member 13 and the power of the laser generating device 20 can be simultaneously controlled by the proportional signal, respectively. Therefore, the rotation rate of the driving rotation member 13 and the power generated by the laser generating device 20 can be synchronized. Preferably, the driving rotation part 13 is implemented as a driving motor for driving the spindle to rotate in the moving device 10.
From the above description, it can be understood by those skilled in the art that the whole laser cladding apparatus can automatically operate because the start and stop of the laser generating device 20 and the output power are synchronized with the driving rotating part 13 and the start and stop part 12 of the moving device 10, respectively. In particular, when the output power of the laser generator 20 is synchronized with the driving rotation member 13 implemented as a spindle driving motor, since the time for which the laser generator 20 stays at one location is inversely proportional to the output power of the laser generator 20, the output power of the laser generator 20 needs to be increased as the rotation speed of the driving rotation member 13 is increased, and the output powers of the driving rotation member 13 and the laser generator 20 can be synchronized, so that the laser cladding apparatus can be operated not only automatically, but also have better coordination between the movement device and the laser generator 20.
Referring to fig. 3, according to another aspect of the present invention, the present invention also discloses a control method of a laser cladding apparatus, wherein the control method of the laser cladding apparatus includes the steps of:
(S1) splitting a control signal for controlling a motion device 10 into at least two control signals, wherein one control signal is used for controlling the motion device 10, and the other control signal is used for controlling the laser generation device 20; and
(S2) synchronously controlling the movement device 10 and the laser generation device 20 according to the split at least two control signals.
According to a preferred embodiment of the present invention, the step (S1) comprises:
splitting at least two start-stop signals of the start-stop component 12, wherein at least one start-stop signal is used for controlling the start-stop component 12, and at least another start-stop signal is used for controlling the start-stop of a laser generating device 20; wherein the step (S2) comprises: the start-stop means 12 and the laser generating device 20 are synchronously controlled in start-stop.
According to a preferred embodiment of the present invention, the step (S1) comprises:
splitting a rotating speed analog signal of the driving rotating part 13 into at least two proportional signals, wherein at least one proportional signal is used for controlling the driving rotating part 13, and at least another start-stop signal is used for controlling the power formed by a laser generating device 20; wherein the step (S2) comprises: and synchronously controlling the power output by the laser generating device 20 according to the proportional signal.
It will be appreciated by persons skilled in the art that the embodiments of the invention shown in the foregoing description are by way of example only and are not limiting of the invention. The objects of the invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the embodiments, and any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
