Description
Technical Field
The present invention generally relates to a head-up display welding helmet equipped with a wireless module.
Background
In order to protect an operator from various harmful rays generated by spatter bruising and arcing during a welding operation, the operator typically wears a welding helmet. In conventional welding masks, the optical filter is a critical component that provides protection for the eyes of the operator from harmful radiation. Conventional welding masks require the operator to look at the welding arc starting location before wearing the mask and then wear the upper mask for blind operation. Such blind operations can cause inconvenience during on-site construction.
For this reason, automatic darkening welding masks have been developed in recent years. Such automatic darkening welding masks are generally equipped with an automatic darkening filter. The main principle of the automatic dimming filter is that the liquid crystal panel is arranged, the liquid crystal panel is transparent before welding and arcing, and the liquid crystal panel is converted into an opaque state at the moment of arcing, so that the protection is provided for the eyes of an operator. Typically, such automatic darkening filters are equipped with adjustment knobs or buttons that an operator must remove the mask to adjust the operating parameters of the automatic darkening filter, such as sensitivity, delay time, shade number, welding mode, etc., before using the welding mask, and then wear the mask for a welding operation. In some welding job sites where repeated changes in operating parameters (e.g., changing welding modes, adjusting sensitivity, etc.) are required, repeated removal/donning of the mask can be physically demanding on the operator and can affect the quality of the weld.
In addition, in the process of taking off the mask, setting parameters and wearing the mask again, the eyes of an operator need to be continuously adjusted to adapt to the change of the ambient light and shade environment, even serious discomfort is generated to individual operators, welding work is further influenced, and even permanent damage is caused to the eyes seriously.
Taking argon arc welding machines as an example, modern welding equipment generally comprises an electric welding machine, a gas cylinder, a welding gun and a welding mask. Before welding, parameters such as current, voltage, welding duration, wire feeding speed and the like of the welding machine are required to be set correspondingly, and a display screen on an operation panel of the welding machine displays the parameter setting correspondingly. The welding machine and the welding mask are connected through a cable, so that an operator wears the welding mask to start working after the parameters of the welding machine and the parameters of the welding mask are set.
Such a connection cable between the welding bug and the welding helmet may trip the operator while the operator is performing the welding work. Furthermore, limited by the length of the cable, it may be possible to restrict the welding work of the operator in certain circumstances. In addition, because the welding site is usually in a severe environment, the connecting cable may be aged after long-term use or broken due to frequent looping, so that the signal connection is not smooth, and the normal use of the welding mask is affected.

Detailed Description
In the various figures of the present application, features that are structurally identical or functionally similar are denoted by the same reference numerals.
According to the Head Up Display (HUD) type automatic light changing filter, an operator can set various operation parameters of the automatic light changing filter without taking down the mask. As shown in FIG. 1, the automatic light changing filter 10 includes a liquid crystal filter lens assembly 10a, a solar cell assembly 10b, and a heads-up display 10 c.
The liquid crystal filter lens assembly 10a and the solar cell assembly 10b are disposed on the body of the automatic light changing filter 10, and the heads-up display 10c is disposed obliquely below the body. The heads-up display 10c is a liquid crystal display on which all operating parameters associated with the automatic light changing filter 10 may be displayed in due course.
It should be noted that, except for the heads-up display 10c and the following description, the basic principles of the automatic light changing filter 10 are substantially similar to those of the automatic light changing filters currently available on the market, and thus, the description of the operation principles of the automatic light changing filter 10 itself is omitted herein.
Control knobs 30 are connected to the automatic dimmer filter 10 via control cables for adjusting the operating parameters thereof. Here, the adjustment of the operating parameter may include a SHADE number (SHADE) adjustment of the automatic light changing filter 10, gears 9-13; SENSITIVITY adjustment (SENSITIVITY), and 0-10 gear; adjusting delay time and shifting 0-10; adjusting the operation mode: welding (WELD), CUTTING (CUTTING), and Grinding (GRIND). These operating parameters can be displayed in a reverse manner on the heads-up display 10 c.
It is noted that in the context of the present invention, "reverse image" for each letter or number to be displayed means that these letters or numbers are displayed on the heads-up display 10c in mirror image up and down and left and right. Additionally, the heads-up display 10c may be a monochrome or color liquid crystal display or any suitable display device as will occur to those of skill in the art.
A glass screen 20 is disposed in front of the automatic darkening filter 10. The glass screen 20 is light transmissive, and particularly transparent, so as not to adversely affect the operational functions of the automatic darkening filter 10 and, at the same time, provides additional protection for the automatic darkening filter 10 from flying debris generated during welding. The heads-up display 10c is disposed with the light emitting surface under the automatic light changing filter 10 inclined toward the glass panel 20 such that when the heads-up display 10c emits light for display, a portion of the light is emitted obliquely upward, passes through the glass panel 200 and a portion of the light is reflected by the glass panel 20 to the human eye, which provides the human eye with an enlarged positive virtual image of the operating parameters as if far in front of the glass panel 20 as shown in fig. 2, so that the operator can conveniently observe various operating parameters related to the automatic light changing filter 10 without taking off the mask.
Fig. 3 schematically illustrates a basic control block diagram of the head-up display type automatic light changing filter. As shown in FIG. 3, a battery is connected to the liquid crystal filter lens assembly 10a via a control circuit and the knob 30 is also connected to the liquid crystal filter lens assembly 10a via the control circuit such that the operating parameters of the automatic darkening filter 10 are adjusted via the knob 30. It should be appreciated that the battery, control circuitry, liquid crystal filter lens assembly 10a and knob 30 (as enclosed by the dashed box in FIG. 3) are substantially identical to the design of prior art automatic darkening filters. The head-up display 10c according to the present invention is connected to a control circuit, when an operator desires to adjust various operating parameters of the auto-darkening filter 10, the control circuit may control the head-up display 10c to display the corresponding control parameters in a reverse manner, and the real-time power of the battery may also be displayed on the head-up display 10 c. It can be seen from this point that the head-up display type automatic light-changing filter according to the present invention can be implemented by simple modification on the basis of the existing automatic light-changing filter, without increasing much manufacturing cost.
In addition, the glass screen 20 may be a transparent organic glass screen or a common glass screen, and in order to increase the light reflection rate, a reflective film may be attached to the glass screen 20, for example, a reflective film commonly found in an automobile or even the glass screen 20 may be made into a dark transparent glass screen, so as to provide a more clearly amplified positive virtual image display in an environment with sufficient external light. Even more, the glass screen 20 may be a transparent protective sheet for protecting the darkening filter on a conventional automatic darkening welding helmet. In addition, the head-up display 10c is not limited to being obliquely disposed below the liquid crystal filter lens group 10a as shown in fig. 2, for example, the head-up display 10c may alternatively be obliquely disposed toward the glass panel 20 on the side of the liquid crystal filter lens group 10 a. That is, any position where the light emitted from the head-up display 10c can be projected onto the glass screen 20 can be adopted for the head-up display 10 c.
Fig. 4 shows a head-up welding helmet 1 according to an embodiment of the present invention, where the head-up welding helmet 1 is equipped with a head-up automatic darkening filter 10 according to the present invention. As can be further seen from fig. 5, the welding mask 1 includes a mask shell 40, a head-up display type automatic darkening filter 10 mounted on a front portion of the mask shell 40, and a headband structure 60. The headgear structure 60 is adapted to be worn directly on the head of the operator and functions to secure the mask shell 40. A substantially rectangular opening 40a is opened in the front portion of the mask case 40, and the support frame 50 is fitted into the opening 40 a. The above-mentioned head-up display type automatic light changing filter 10 is mounted on the support frame 50 such that the light emitting surface of the head-up display 10c of the automatic light changing filter 10 is directed obliquely upward as shown in fig. 4 after the support frame 50 is fixed on the mask case 40.
The knob 30 for adjusting the automatic light changing filter 10 is provided on the mask case 40 so that an operator can easily perform a parameter adjusting operation by directly operating the knob 30 with hands while wearing the mask 1. The transparent protect sheet 20' is disposed in front of the automatic darkening filter 10 at the opening 40a of the mask case 40. It should be clear that the transparent protective sheet 20' may be a glass screen 20 as shown in fig. 1 and 2. The distance between the transparent protective sheet 20 'and the automatic light changing filter 10, in particular the liquid crystal filter lens group 10a, and the inclination of the obliquely arranged head-up display 10c are set such that a virtual image of the head-up display 10c located below, which is transmitted through the transparent protective sheet 20' when emitting light, is just observable by the eyes of the mask wearer.
The following schematically describes the mounting configuration of the automatic darkening filter 10 within the mask shell 40. As shown in fig. 5 and 6, the support frame 50 is generally in the form of a rectangular frame having a flange 50a extending inwardly on a side thereof adjacent the head of the wearer. The flange 50a is shaped to conform to the body of the automatic light changer 10 and its heads-up display 10c such that the body of the automatic light changer 10 and its heads-up display 10c fit snugly over the flange 50 a. A support flange 50b is provided on the underside of the support frame 50, the support flange 50b being configured to abut the heads-up display 10c upwardly to prevent the automatic light changer 10 from falling out of the support frame 50. It should be appreciated that the automatic darkening filter 10 may be secured to the support frame 50 in any suitable manner known to those skilled in the art, such as, for example, adhesive bonding, screw-on structures, crimping structures, snap-fit structures, etc.
The opening 40a of the mask shell 40 is peripherally formed with two flanges 40a and 40 b. The support frame 50 is fitted on this flange 40a via its front flange 50c, and then the protect sheet 20 'is interposed between this flange 40b and the support frame 50 in the front-rear direction, and the protect sheet 20' is fixed by the clamping force between the flange 40b and the support frame 50. It should be appreciated that any suitable securing means, such as adhesive, screw attachment, crimping, snap-fit, etc., may be used to secure the protective sheet 20' between the support frame 50 and the mask shell 40 within the opening 40a of the mask shell 40.
In using the welding mask 1 of the present invention, the operator may wear the welding mask 1 on the head, then turn on the adjusting knob 30, and virtually image the parameter information via the transparent protective sheet 20' to the front of the eyes of the operator via the head-up display 10 c. Therefore, an operator can directly start arc welding without taking off or wearing a mask like the prior art after adjusting the operation parameters, the labor intensity is obviously reduced, and the working efficiency is improved. In addition, by adopting the welding mask 1 provided by the invention, an operator can directly adjust or check various operating parameters of the automatic light-changing filter without taking off the mask, so that the eyes do not need to adapt to the light and shade change of the ambient environment, the discomfort of the eyes is reduced, and the eyes of the operator are further reliably protected.
Although in the illustrated embodiment, the heads-up display 10c is designed integrally with the body carrying the liquid crystal filter lens stack 10a and the solar cell stack 10 b. However, it should be apparent to those skilled in the art that the heads-up display 10c may be designed separately from the body of the automatic darkening filter 10. For example, the heads-up display 10c may alternatively be manufactured separately from the body of the auto-darkening filter 10 and then connected to the body of the auto-darkening filter 10 and the knob 30, respectively, via a data cable. In this way, the arrangement position of the heads-up display 10c in the mask case 40 can be selected more conveniently, for example, at a position more favorable for virtual image arrangement. In addition, as an alternative, the heads-up display 10c may also be arranged on the left or right side of the body of the automatic light changing filter 10 or even above, as long as ensuring that the heads-up display 10c is tilted towards the protective sheet 20' to be able to be viewed as a virtual image suitably by the wearer.
In addition, as mentioned above, the transparent protect sheet 20' in the face mask 1 may be the glass screen 20 shown in fig. 1 and 2. However, since spatter may directly collide against the protect sheet 20 'or the glass screen 20 during welding to cause surface abrasion, thereby causing image formation to be unclear to affect observation of the operation parameters, the protect sheet 20' or the glass screen 20 can be detachably mounted on the mask case 40. For example, alternatively, a plurality of removable snap structures may be provided on the mask shell 40 around the opening 40a to removably lock the protective sheet 20' or glass screen 20 to the mask shell 40. In this way, if excessive wear of protective sheet 20 'or glass screen 20 affects the viewing, a new protective sheet 20' or glass screen 20 can be replaced. For another example, it is even possible to use a hole punched in the protective sheet 20 ' or the glass screen 20 and the mask case 40, respectively, and fix the protective sheet 20 ' or the glass screen 20 to the mask case 40 using a screw, so that the protective sheet 20 ' or the glass screen 20 can be replaced with a new one by directly unscrewing the screw, if necessary. In general, any removable securing structure that may occur to those skilled in the art may be employed between the protective sheet 20' or glass screen 20 and the mask shell 40.
In addition, protective sheet 20' may also be made translucent or dark to provide further assurance of clear image formation. In addition, the protective sheet 20' may be a protective sheet of a conventional auto-darkening filter mask, and serves as a reflective screen of a head-up display by attaching a light-transmitting reflective film on the outer surface thereof. Thus, when the imaging is not clear due to welding spatter in a period of use, the imaging can be clearly performed again only by tearing off the old film and attaching the new film.
Unlike prior art welding masks, an operator may wear a welding mask according to the present invention directly, and then adjust the parameters by manually adjusting the knobs after the heads-up display is turned on to image the operating parameters to the front of the protective sheet; then, the welding operation can be performed by directly starting the arc after the head-up display is turned off. In addition, in the process of welding operation, in order to change the operation parameters or change the welding mode, the head-up display can be started again when the automatic light-changing filter is in a transparent state, various operation parameters are correspondingly adjusted, and then arc striking is performed again to perform welding operation. Therefore, by adopting the welding mask with the head-up display type automatic light-changing filter, an operator does not need to take off the mask, adjust parameters and then wear the mask as in the prior art, can directly wear the mask to adjust related operating parameters, improves the working convenience, ensures that eyes do not feel uncomfortable due to rapid change of ambient light, and improves the working efficiency. In addition, by adopting the head-up display type welding mask, an operator is particularly suitable for welding work in a dark environment, because the image formed by the head-up display is clearer.
An embodiment of a welding apparatus equipped with the above-described head-up welding helmet of the present invention will be described with further reference to fig. 3, 4 and 7. The welding apparatus includes a welding bug 300, a gas cylinder 400 (e.g., an argon gas cylinder), a welding torch 500, and a heads-up display welding helmet 1. The welding bug 300, gas cylinder 400, and welding gun 500 are connected via cables as known in the art. The welding machine 300 is provided with a wireless communication module 100 a. The wireless communication module 100a is connected to the welding machine circuit 301, and can be used to send signals related to the operation parameters of the welding machine, such as current level, voltage level, dc or ac display, and welding gun operation time, and after receiving the control command, the wireless communication module can set the welding machine circuit accordingly, so as to change the operation parameters of the welding machine accordingly.
A wireless communication module 100b is also provided on the head-up welding helmet 1 of the present invention. For example, as shown in fig. 4, the wireless communication module 100b is disposed on the mask case 40 above the protect sheet 20' or the glass screen 20. It should be clear to those skilled in the art that the wireless communication module 100b may be disposed on any portion of the mask shell 40 that does not interfere with the transmission or reception of signals. The wireless communication module 100b is mounted as a separate accessory on the outer surface of the mask shell. Alternatively, however, the wireless communication module 100b may be designed to be integrated with the automatic light-changing filter 10 in advance.
The wireless communication module 100b may be connected to a control circuit for controlling the head-up display 10c as shown in fig. 3, so that a control command may be issued to the outside via the wireless communication module 100b under the control of the knob 30.
The wireless communication modules 100a and 100b may be wireless networking technology-based (WIFI) modules, bluetooth modules, infrared communication modules, or any other communication modules that can implement wireless data connection. In this way, various operating parameters of the welder 300 can be imaged onto the glass screen 20 in real time via the wireless communication modules 100a and 100b and the heads-up display 10 c. In particular, various operating parameters of the welder 300 can be imaged in a manner similar to that shown in FIG. 2. For the sake of brevity, it will not be described in detail herein.
For example, after the welding mask 1 is worn by the operator, the operating parameters of the automatic darkening filter 10 and the operating parameters of the welding bug 300 may be simultaneously imaged onto the glass screen 20 via the wireless communication modules 100a and 100b for the wearer to view. Then, the operator presses the knob 30 and rotates the knob 30 so that a highlight appears on the virtual image corresponding to the corresponding one of the operation parameters, for example, the current. The knob 30 may then be rotated to increase or decrease the current parameter by pressing it again. After the current level is selected, the knob 30 is pressed again to complete the adjustment. The above description has described only one exemplary embodiment of adjusting the operating parameter by operation of the knob 30. It will be clear to a person skilled in the art that other suitable embodiments of the knob 30 can be redesigned, after having understood the corresponding principles.
For the welding mask with the wireless communication module, an operator is not limited by a cable between the welding mask and the electric welding machine in the prior art any more, so that any constraint during welding is avoided, and meanwhile, the operating parameters of the electric welding machine can be observed by the operator in real time and correspondingly adjusted, so that the operator can conveniently adjust the operating parameters of the electric welding machine at any time according to construction welding requirements, and the working efficiency is improved.
Although specific embodiments of the invention have been described herein in detail, they have been presented for purposes of illustration only and are not to be construed as limiting the scope of the invention. Various substitutions, alterations, and modifications may be devised without departing from the spirit and scope of the present invention.
