Abstract
An apparatus indirectly measuring solder wire feeding speed belongs to the technical field of measuring equipment. The apparatus indirectly measuring solder wire feeding speed comprises a speed detection unit, a signal processing unit (2) and a display unit (3). The speed detection unit is composed of a light source (101), a lens (102) and a photoelectric sensor (103). The light emitted by the light source (101) is projected onto the surface of a to-be-measured solder wire. The lens (102) is disposed on a reflection light path of the surface of the to-be-measured solder wire. The photoelectric sensor (103) is disposed at a reflected end of a reflected ray of the lens (102). The output of the photoelectric sensor (103) is connected to the signal processing unit (2). An input end of the signal processing unit (2) is connected to the display unit (3). The photoelectric sensor (103) transmits a pulse signal or a data packet to the signal processing unit according to the received ray; then after processing by the signal processing unit (2), the solder wire feeding speed data is acquired and then is displayed through the display unit (3). The non-contact measuring method of the apparatus indirectly measuring the solder wire feeding speed overcomes defects such as contact-type measuring error and wearing.
Description
Technical field:
The present invention relates to the improvement to solder wire convey motor speed pick-up unit, and it realizes the detection of welding wire speed of feed is belonged to technical field of measuring equipment by adopting the photoelectric sensor measurement.
Technical background:
Wire feed rate is an important parameters of welding, but exist many reasons to cause welding wire feeding speed not stablize, the solder wire convey machine is in order to improve the stability of wire feed, usually need to adopt the printed motor with big torque and less armature inertia, motor driven systems also adopts the velocity feedback compensating circuit that wire feed rate is regulated.Obtaining wire feed rate is the key of this step, is traditional mode that tests the speed by DC tachometer generator and photoelectric encoder; Though can not obtain the real-time speed of welding wire intuitively by the feedback to the variation of armature supply and voltage, also can regulate wire feed rate.But these methods all are the indirect measurements to the speed feeding of welding wire, and the error that produces of skidding of wire feed rolls and welding wire can not obtain measuring.A lot of Enterprises Reaction are during for the accurate relatively wire feed rate of needs, and these methods can not well meet the demands.
At as above some problems, prove that by experiment photoelectric sensor can well measure the welding wire speed of feed.
Summary of the invention:
The present invention can provide a kind of precision higher, the device that more stable welding wire feeding speed is measured indirectly.The present invention can be by following realization:
A kind of device of indirect measurement welding wire feeding speed comprises speed detection unit, signal processing unit 2 and display unit 3.Speed detection unit is made up of light source 101, lens 102 and photoelectric sensor 103; The light that light source 101 sends projects on the welding wire surface, lens 102 are set on the reflected light path of welding wire surface, the exit end of lens 102 arranges photoelectric sensor 103, and the output of photoelectric sensor 103 is connected to signal processing unit 2, and the output terminal of signal processing unit 2 is connected to display unit 3.By the difference of contrast acceptance pattern picture, the photoelectric sensor 103 different pulse signals of transmission or packet are to signal processing unit 2, and through the processing of signal processing unit 2, the data that obtain are carried out the demonstration of welding wire feeding speed by display device 3.
The present invention can obtain following beneficial effect:
The present invention can realize the measurement to the welding wire speed of feed.Avoided the shortcoming of contact type measurement error wearing and tearing etc. as non-contacting measuring method.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Among the figure: 101, light source, 102, lens, 103, photoelectric sensor, 2, signal processing unit, 3, display unit.
Embodiment:
Below in conjunction with accompanying drawing invention is further specified
A kind of device of indirect measurement welding wire feeding speed comprises speed detection unit, signal processing unit 2 and display unit 3.Speed detection unit is made up of light source 101, lens 102 and photoelectric sensor 103; The light that light source 101 sends projects on the measured welding wire surface, lens 102 are set on the reflected light path of tested welding wire surface, the emergent light exit end of lens 102 arranges photoelectric sensor 103, the output of photoelectric sensor 103 is connected to signal processing unit 2, and the output terminal of signal processing unit 2 is connected to display unit 3.Accept the difference of light by contrast, photoelectric sensor 103 sends different pulse signals or packet to signal processing unit 2, and through the processing of signal processing unit 2, the data that obtain are carried out the demonstration of the speed of measured welding wire by display unit 3.
Consult Fig. 1, whole speed detection system as shown in the figure, situation as shown in the figure when object being measured is welding wire, when welding wire process speed detection unit 1, the illumination of being sent by light source 101 is mapped on the welding wire 4, light being integrated in the photoelectric sensor 103 via lens 102 that the measured welding wire surface of process reflects, photoelectric sensor 103 difference of every fixed interval section imaging by analysis sends to signal processor 2 with the mobile value of unique point, analytical calculation through signal processing apparatus obtains welding wire feeding speed, the output digital signal shows by display unit 3, photoelectric sensor 103 planted agents encapsulate this corresponding dsp chip and sensitization camera lens, and solidify some algorithms or function, the image that obtains is calculated reaction capacity fast, so that the reaction velocity of total system.Determine it to have certain dirigibility according to the characteristics of speed detector, portability can be installed in a lot of positions of electric welding machine.
