Description

Anti-glare welding equipment
Technical Field
The invention relates to welding equipment, in particular to anti-dazzle welding equipment.
Background
The welding worker needs to wear the welding mask during working, and the welding mask can protect eyes, faces and necks of the welding worker from flash burning caused by welding arc light generated during welding or avoid the influence of ultraviolet rays, sparks, infrared rays and heat.
A typical welding helmet is configured with a dark lens to allow a welder to clearly see the welding position through the dark lens, and to block the welding arc through the dark lens, thereby protecting the eyes of the welder. However, when the welder is not working, the welder cannot clearly see the surrounding environment through the dark lens. Therefore, the welding worker must remove the welding helmet to clearly see the surrounding environment.
In addition, there is another welding mask having a lens with a function of automatically adjusting a light transmittance, the color of the lens is automatically darkened when a welding arc light is generated, and the color of the lens is automatically lightened when no welding arc light is generated. Therefore, the welder wearing the welding mask can clearly see the surrounding environment by observing the lens with the lightened color when not performing the welding work.
However, the welding mask with a lens capable of automatically adjusting transmittance automatically adjusts the light transmission path of the lens by detecting whether the welding arc is generated or not, but a period of time for color conversion still passes from the detected welding arc to the control of the color darkening of the lens, and the color darkening of the lens cannot be currently generated at the time of the welding arc, so that a part of the welding arc still passes through the lens during the time of the color conversion, and the eye of a welder is damaged, and thus the conventional welding mask needs to be further improved.
Disclosure of Invention
In view of the disadvantage that the eyes of the welder are damaged due to partial welding arc light passing through the lens in the time of the color conversion of the lens of the existing welding mask with the lens capable of automatically adjusting the light transmittance, the invention provides an anti-glare welding device to prevent the eyes of the welder from being damaged due to the welding arc light passing through the lens in the time of the color conversion of the lens. The anti-glare welding apparatus includes:
a switch having a start state and a stop state;
and the controller is electrically connected with the switch, generates a mask starting signal when judging that the switch is converted from the closing state to the starting state, wirelessly sends the mask starting signal, and further generates a welding machine starting signal after a first delay time and sends the welding machine starting signal.
When a welder presses the switch to prepare for welding, the controller generates a mask starting signal firstly and wirelessly sends the mask starting signal to control the color of a lens of a welding mask to be darkened, and the welder starting signal is generated after the first delay time to start the welder to start welding. In the first delay time, the color of the lens of the welding mask is sufficiently darkened, that is, the welding machine is started to start welding after the first delay time, that is, after the color of the lens of the welding mask is darkened, the welding machine also generates the welding arc. Therefore, the welding arc is generated after the color of the lens of the welding mask is darkened, so that the condition that the welding arc passes through the lens to hurt the eyes of a welder in the time of lens color conversion can be avoided, and the eyes of the welder are further protected.

Detailed Description
The technical means adopted by the invention to achieve the predetermined object of the invention are further described below with reference to the drawings and the preferred embodiments of the invention.
Referring to fig. 1, a first embodiment of the anti-glare welding apparatus of the present invention includes a switch 10 and a controller 20. The switch 10 has an on state and an off state. The controller 20 is electrically connected to the switch 10. When the controller 20 determines that the switch 10 is switched from the off state to the on state, the controller 20 generates a mask start signal and wirelessly transmits the mask start signal, and the controller 20 further generates a welding machine start signal after a first delay time and transmits the welding machine start signal.
Further, the anti-glare welding apparatus further includes a welding gun 30, a welding machine 40, and a welding mask 50. And as shown in fig. 2, the switch 10 is disposed on a housing 31 of the welding gun 30. The welder 40 is electrically connected to the welding gun 30 and the controller 20, and when the welder 40 receives the welder start signal, the welder 40 supplies power to the welding gun 30.
As shown in fig. 3, the welding helmet 50 has a liquid crystal filter 51, and is wirelessly connected to the controller 20, and when the welding helmet 50 wirelessly receives the helmet start signal sent by the controller 20, the welding helmet 50 controls the color of the liquid crystal filter 51 to be darkened to reduce a light transmittance thereof.
For example, when a welder does not press the switch 10, the switch 10 is in the off state, the welder 40 does not provide power to the welding gun 30, and the welder does not need to perform a welding operation and does not generate welding arc. Since the welding helmet 51 does not receive the helmet activation signal, the color of the liquid crystal filter 51 does not become dark, and thus the welding worker can clearly see the surrounding environment.
When the welder presses the switch 10, it indicates that the welder wants to perform a welding operation, the switch 10 is switched from the off state to the on state, and the controller 20 detects that the switch 10 is switched from the off state to the on state, so the controller 20 generates the mask start signal and wirelessly sends the mask start signal to the welding mask 50. And when the welding helmet 50 receives the helmet starting signal, the welding helmet 50 controls the color of the liquid crystal filter 51 to be darkened, so as to reduce the light transmittance of the liquid crystal filter 51, thereby protecting the eyes of the welding worker.
And when the controller 20 detects that the switch 10 is switched from the off state to the on state, the controller generates the welder start signal after the first delay time in addition to the mask start signal, and sends the welder start signal to the welder 40, so that the welder 40 supplies power to the welding gun 30, and a welder can perform a welding operation.
Since the welder start signal is generated after the first delay time of the mask start signal, that is, the welder 40 starts the welding operation after the welder presses the switch 10 for the first delay time, the mask start signal is transmitted to the welding mask 50 when the welder presses the switch 10, so that the color of the liquid crystal filter 51 of the welding mask 50 is darkened. In the first delay period, the color of the liquid crystal filter 51 of the welding mask 50 is sufficiently darkened, so that the color of the liquid crystal filter 51 of the welding mask 50 is completely darkened before the welder 40 supplies power to the welding gun 30 to enable a welder to perform a welding operation, and a welding arc generated during the welding operation is not allowed to pass through, thereby protecting eyes of the welder.
In addition, in the present embodiment, the controller 20 includes a switch state detecting unit 21, a first delay time controlling unit 22, a wireless signal encoding unit 23 and a wireless signal transmitting unit 24.
The switch state detection unit 21 is electrically connected to the switch 10 to detect whether the switch 10 is in the on state or the off state, and generates an on signal when the switch 10 is switched from the off state to the on state. The first delay time control unit 22 is electrically connected to the switch state detection unit 21, and when the first delay time control unit 22 receives the start signal generated by the switch state detection unit 21, the first delay time control unit 22 generates and sends the welder start signal to the welder 40 after the first delay time.
The wireless signal encoding unit 23 is electrically connected to the switch state detecting unit 21, and when the wireless signal encoding unit 23 receives the start signal generated by the switch state detecting unit 21, the wireless signal encoding unit 23 encodes the start signal into the mask start signal. The wireless signal transmitting unit 24 is electrically connected to the wireless signal encoding unit 23 to receive the mask starting signal generated by the encoding of the wireless signal encoding unit 23, and directly wirelessly transmits the mask starting signal to the welding mask 50.
Further, when the controller 20 determines that the switch 10 is switched from the on state to the off state, the controller 20 generates a mask off signal and wirelessly transmits the mask off signal to the welding mask, and the controller generates a welder off signal and transmits the welder off signal.
When the welder 40 receives the welder-off signal, the welder 40 stops supplying power to the welding gun 30. And when the welding mask 50 wirelessly receives the mask closing signal, the welding mask 50 controls the color of the liquid crystal filter 51 to become lighter after a second delay time to increase a light transmittance thereof.
For example, when the switch 10 is pressed by the welder while the welding operation is being performed, the switch 10 is in the activated state, and the welder 40 normally supplies power to the welding gun 30. At this time, the welding mask 51 is darkened by receiving the mask activation signal, so as to protect the eyes of the welding worker.
When the welder releases the switch 10, indicating that the welder intends to stop welding, the switch 10 is switched from the on state to the off state, and the controller 20 detects that the switch 10 is switched from the on state to the off state, so that the controller 20 generates the mask off signal and wirelessly transmits the mask off signal to the welding mask 50. When the welding helmet 50 receives the helmet closing signal, the welding helmet 50 controls the color of the liquid crystal filter 51 to become lighter after the second delay time, so as to increase the transmittance of the liquid crystal filter 51, thereby allowing the welding worker to clearly see the surrounding environment.
And when the controller 20 detects that the switch 10 is switched from the on state to the off state, the controller further generates the welder-off signal in addition to the mask-off signal, and sends the welder-off signal to the welder 40, so that the welder 40 stops supplying power to the welding gun 30, and a welder can stop welding.
Since the welder-off signal and the mask-off signal are generated simultaneously, that is, the welder 40 stops supplying power to the welding gun 30 to stop the welding operation and suspend the generation of the welding arc after the welder releases the switch 10. However, when the welder releases the switch 10, although the mask activation signal is wirelessly transmitted to the welding mask 50, the welding mask 50 further waits for the second delay time before the color of the liquid crystal filter 51 begins to become dark. Therefore, at the moment of stopping the welding operation and in the second delay time thereafter, it is enough that the color of the liquid crystal filter 51 of the welding mask 50 does not become light and the welding arc generated before the welding operation is stopped is not allowed to pass, thereby protecting the eyes of the welding worker, and at the same time, the color of the liquid crystal filter 51 is allowed to become light only at the second delay time after the welding operation is stopped, so that the welding worker can clearly see the surrounding environment and has to take off the welding mask 50.
In the present embodiment, when the switch state detection unit 21 detects that the switch 10 is switched from the on state to the off state, a turn-off signal is generated. When the first delay time control unit 22 receives the turn-off signal generated by the switch state detection unit 21, the first delay time control unit 22 directly generates and sends the welder turn-off signal to the welder 40.
When the wireless signal encoding unit 23 receives the closing signal generated by the switch state detecting unit 21, the wireless signal encoding unit 23 encodes the closing signal into the mask closing signal. The wireless signal transmitting unit 24 receives the mask closing signal generated by the wireless signal encoding unit 23, and directly wirelessly transmits the mask closing signal to the welding mask 50.
In addition, the anti-glare welding apparatus further includes a battery 60 electrically connected to the controller 20 for providing power to the controller 20.
Referring to fig. 4, it can be seen that when the controller 20 detects that the switch 10 is switched from the OFF state to the ON state, as shown by the rising edge of the switch control signal in fig. 4, the controller 20 also synchronously generates the mask start signal, as shown by the rising edge of the mask control signal in fig. 4, and when the welding mask 50 receives the mask start signal, the controller synchronously controls the ON state of the liquid crystal filter 51 to be switched from the OFF state (OFF) to the ON state (ON), so that the color of the liquid crystal filter 51 begins to become dark, as shown by the rising edge of the liquid crystal filter start state waveform in fig. 4. However, after the controller 20 generates the mask start signal, it is necessary to wait for the first delay time t1 to generate the welder start signal to allow the welder 40 to supply power to the welding gun 30, as shown by the rising edge of the welder control signal in fig. 4.
However, when the controller 20 detects that the switch 10 is switched from the on state to the off state, as shown by the falling edge of the switch control signal in fig. 4, the controller 20 also synchronously generates the mask off signal and the welder off signal, as shown by the falling edge of the mask control signal and the welder control signal in fig. 4, so that the welder 40 directly stops supplying power to the welding gun 30 due to receiving the welder off signal.
However, when the welding mask 50 receives the mask closing signal, the start state of the liquid crystal filter 51 is controlled to be switched from the ON state (ON) to the OFF state (OFF) after the second delay time t2, so that the color of the liquid crystal filter 51 starts to become lighter, as shown by the falling edge of the waveform of the start state of the liquid crystal filter in fig. 4.
In the present embodiment, the first delay time t1 is greater than or equal to 0.05 seconds, and the second delay time t2 is greater than or equal to 0.01 seconds, but not limited thereto.
In addition, as shown in fig. 5, the welding mask 50 includes the liquid crystal filter 51, a wireless signal receiving unit 52, a decoding unit 53, a control unit 54, a dc/ac conversion unit 55, an adjusting unit 56, a user interface 57, a solar panel 58 and a battery unit 59.
The decoding unit 53 is electrically connected to the wireless signal receiving unit 52 and the control unit 54, so as to wirelessly receive the mask starting signal or the mask closing signal through the wireless signal receiving unit 52, decode the mask starting signal or the mask closing signal, and transmit the decoded mask starting signal or the decoded mask closing signal to the control unit 54. The control unit 54 is electrically connected to the dc/ac conversion unit 55 and the adjustment unit 56, and the user interface 57 is electrically connected to the adjustment unit 56. The user interface 57 allows the welder to adjust the color shade of the liquid crystal filter 51. The adjusting unit 56 generates an adjusting signal according to the state of the user interface 57, and transmits the adjusting signal to the control unit 54. The control unit 54 generates a corresponding control signal to control the color of the liquid crystal filter 51 through the dc/ac conversion unit according to the adjustment signal and the decoded mask start signal or mask close signal.
The solar panel 58 is electrically connected to the battery unit 59 to receive solar energy and convert the solar energy into electric energy to charge the battery unit 58. The battery unit 54 is electrically connected to and supplies power to the liquid crystal filter 51, the wireless signal receiving unit 52, the decoding unit 53, the control unit 54, the dc/ac conversion unit 55, the adjusting unit 56, and the user interface 57.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
