Description

Technical Field

[0001] This invention relates to the field of handheld processing technology, and more particularly to a rotary button device, a handheld laser gun head, and a laser processing apparatus. Background Technology

[0002] The operating buttons of existing handheld laser gun heads are generally fixed around the handle. The handle has separate light emission and wire feeding buttons. The light emission button is used to control the laser emission module to emit or cut off the light, and the wire feeding module is used to control or stop wire feeding. The handle can also have any function buttons that may exist during laser processing, and the position of the buttons corresponds to the user's grip. However, this setting is only suitable for fixed welding techniques, resulting in the user's welding techniques being relatively fixed and monotonous.

[0003] As a result, when operating space is limited in complex welding environments or during the processing of certain special parts, the placement and angle of the handheld laser gun head will be restricted, and the operation of the buttons will also be limited, thereby affecting operating efficiency and welding quality. Restricted button operation by the user may lead to delayed button triggering, potentially causing problems such as delayed wire breakage or delayed laser emission, or making button control very difficult, resulting in reduced processing quality. Summary of the Invention

[0004] The purpose of this invention is to provide a rotary button device, a handheld laser gun head, and a laser processing device. The button position is flexible, and the operation method is not limited by angle and space, making it easy to change the on / off state of the function in a timely manner, thereby further improving the processing quality. In addition, it can solve the problem of hand fatigue caused by users maintaining a single action to operate the button for a long time, thus improving the user experience.

[0013] As an optional technical solution for the rotary button device, the button assembly is a push switch or a touch switch, and can achieve conduction between the positive electrode rotary connection component and the negative electrode rotary connection component under the action of external force.

[0014] As an optional technical solution for the rotary button device, the second conductive element is a flexible conductive element with elastic force, and the second conductive element is fixedly disposed on the inner ring; when the first conductive element is configured as a closed ring structure, the second conductive element is configured as a closed ring structure or an open ring structure.

[0016] As an optional technical solution for the rotary button device, the second conductive element includes a first elastic element and a conductive connector connected together, wherein the first elastic element can provide the conductive connector with an elastic force that abuts against the first conductive element.

[0017] As an optional technical solution for the rotary button device, the rotary button device includes a bendable wire for electrical connection to the button assembly.

[0018] As an optional technical solution for the rotary button device, the rotary button device includes a plurality of rotary positioning locks, which are disposed between the inner ring and the button support ring; or, the rotary button device includes a housing, the inner ring and the housing are connected, and the rotary positioning lock is disposed between the button support ring and the housing, so as to lock the button support ring at the current position after the button support ring rotates relative to the inner ring by a predetermined angle.

[0019] As an optional technical solution for the rotary button device, the rotary positioning lock includes a connected third elastic element and a spherical pin. The third elastic element is disposed inside the button support ring, and the end of the spherical pin is curved.

[0020] As an optional technical solution for the rotary button device, the rotary positioning lock includes a ratchet and a pawl. One of the inner ring and the button support ring is provided with the ratchet, and the other of the inner ring and the button support ring is provided with the pawl, so that the inner ring and the button support ring rotate intermittently relative to each other.

[0023] The beneficial effects of this invention are:

[0024] The rotary button device provided by the present invention includes: an inner ring, a button support ring, a button assembly, and a rotary connection assembly.

[0025] (1) When the button bracket ring rotates the button assembly and the first conductive member along the central axis of the inner ring by a predetermined angle under the action of external force, the first conductive member and the second conductive member remain in contact and can rotate relative to each other. This structure realizes that after the button assembly rotates around the inner ring by a predetermined angle, the button assembly can always be connected by rotating the connecting component, which effectively avoids the circuit entanglement or breakage caused by the rotation operation, and improves the reliability, service life and user experience of the device.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0050] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0053] like Figures 1 to 13 As shown, this invention discloses a rotary button device, a handheld laser gun head, and a laser processing device. The rotary button device includes an inner ring 300, a button support ring 400, a button assembly 411, and a rotary connection assembly. The button support ring 400 and the inner ring 300 are coaxially sleeved and can rotate relative to each other. The button assembly 411 is disposed on the button support ring 400. The rotary connection assembly includes a first conductive member 110 and a second conductive member 120 disposed along the axial or radial direction of the inner ring 300. The first conductive member 110 is disposed on the button support ring 400 and electrically connected to the button assembly 411, and the second conductive member 120 is disposed on the inner ring 300. When the button support ring 400 rotates the button assembly 411 and the first conductive member 110 along the central axis of the inner ring 300 by a predetermined angle under the action of external force, the first conductive member 110 and the second conductive member 120 remain in contact and can rotate relative to each other. This structure ensures that after the button assembly 411 rotates around the inner ring 300 by a predetermined angle, the button assembly 411 can always be connected through the rotational connection component, effectively avoiding wire entanglement or breakage caused by rotational operation, and improving the reliability, service life and user experience of the device. The rotational design of the button assembly 411 can solve the problem that other parts may interfere with the user's ability to trigger the button when processing in a confined space; it can also solve the problem of hand fatigue caused by the user maintaining a single action to operate the button for a long time, improving the user experience; this design ensures that the button rotation conduction is achieved while also ensuring the compact size of the structure.

[0054] Specifically, there are two rotary connection components, arranged axially or radially along the inner ring 300. One rotary connection component is a positive rotary connection component 100, and the other is a negative rotary connection component 200. An insulating ring 130 is provided between the positive rotary connection component 100 and the negative rotary connection component 200 to prevent short circuits. The button support ring 400 has a clearance area 401 for the first wire 61 to pass through. The negative rotary connection component 200 and the positive rotary connection component 100 are respectively connected to the button assembly 411 through the first wire 61.

[0055] Optionally, the button assembly 411 is a push switch or a touch switch, and can achieve conduction between the positive electrode rotation connection component 100 and the negative electrode rotation connection component 200 under the action of external force. In this embodiment, the button assembly 411 is a purchased contact switch, and the second elastic element 413 and the button pressing block 410 form a lever structure triggering mechanism. The mounting base 414 is set on the button support ring 400, one end of the button pressing block 410 is rotatably mounted on the mounting base 414 through the rotating shaft 412, and the other end of the button pressing block 410 is connected to the button support ring 400 through the second elastic element 413. When the user presses the other end of the button pressing block 410, the second elastic element 413 is compressed and touches the trigger part 4110 on the left side of the button assembly 411, triggering the button effect, such as... Figure 2 As shown, the two terminals on the right side of the button assembly 411, the third terminal 4111 and the fourth terminal 4112, are electrically connected to the first terminal 1105 and the second terminal 1205 by means of the first wire 61 or by soldering.

[0056] The handheld laser gun head includes the aforementioned rotary button device, as well as a handle 10 connected to the main body of the gun and a control board (not shown in the figure). The inner ring 300 is fixedly connected to the handle 10, and the button support ring 400 and the button pressing block 410 can rotate around the handle 10. A wiring area 310 is provided on the inner side of the inner ring 300, which is connected to the positive electrode wire avoidance part 302 and the negative electrode wire avoidance part 303 respectively. The control board (not shown in the figure) is located in the wiring area 310. The first conductive member 110 of the positive electrode rotary connection component 100 and the third conductive member 210 of the negative electrode rotary connection component 200 are respectively connected to the control board (not shown in the figure) through the second wire 71. The button pressing block 410 simultaneously connects the positive electrode rotary connection component 100 and the negative electrode rotary connection component 200, thereby realizing the corresponding function of the control board (not shown in the figure). The button pressure block 410, after rotating at any angle relative to the handle 10, makes controlling functions such as laser emission and filament output safer and effectively prevents accidental triggering. This allows for operation without being limited by angle or space, and avoids delays in laser emission, laser cut-off, filament output, and filament breakage, further improving processing quality. Simultaneously, it solves the problem of hand fatigue caused by maintaining a single button operation for extended periods, enhancing the user experience. The laser processing device is comprised of this handheld laser gun head.

[0057] Specifically, such as Figures 7 to 13 As shown, the second conductive element 120 can be a flexible conductive element with elastic force, specifically a hollowed-out serpentine spring, and the second conductive element 120 is fixedly disposed on the inner ring 300. When the first conductive element 110 is configured as a closed ring structure, the second conductive element 120 is configured as a closed ring structure or an open ring structure. When the first conductive element 110 is configured as an open ring structure, the second conductive element 120 is configured as an open ring structure. The first conductive element 110 includes an open segment 1102 and a conductive segment 1101. The central angle of the arc corresponding to the open segment 1102 and the central angle of the arc corresponding to the conductive segment 1101 are mutually circumferential, forming a 360° circle. Similarly, the second conductive element 120 includes a spring contact conductive segment 1202 and an open segment 1201. The central angle of the arc corresponding to the spring contact conductive segment 1202 and the central angle of the arc corresponding to the open segment 1201 are mutually circumferential. The conductive segment 1101 and the spring contact conductive segment 1202 are at least partially in contact, and the central angle of the arc corresponding to the open segment 1102 is smaller than the central angle of the arc corresponding to the spring contact conductive segment 1202.

[0058] Furthermore, the second conductive element 120 includes a first elastic element 1203 and a conductive connector 1204 connected together. The first elastic element 1203 provides an elastic force to the conductive connector 1204 to abut against the first conductive element 110. Figure 11 and Figure 12As shown, the second conductive element 120 can be made from a motor carbon brush. The assembly structures of the first conductive element 110 and the second conductive element 120, arranged axially or radially along the inner ring 300, are illustrated. In other embodiments, such as... Figure 13 As shown, the second conductive element 120 can also be made of a spring pin, and the conductive connector 1204 should be a spring ball with a curved contact surface. Similarly, the fourth conductive element 220 can also be assembled with the third conductive element 210 in the negative electrode rotary connection assembly 200 in the same way.

[0059] Optionally, the first conductive element 110 and the third conductive element 210 have the same structure; the second conductive element 120 and the fourth conductive element 220 have the same structure.

[0060] The rotary button device includes a bendable wire for electrical connection to the button assembly 411. One of the two contacts of the third terminal 4111 and the fourth terminal 4112 is connected to the wound wire, which replaces the first conductive element 110 of the positive rotary connection assembly 100 or the third conductive element 210 of the negative rotary connection assembly 200.

[0061] For example, the rotary button device further includes a rotary positioning lock 5, which selectively engages the inner ring 300 with the button support ring 400, thereby fixing the position of the button pressing block 410 after it rotates a predetermined angle. Alternatively, the rotary button device includes a housing 500, with the inner ring 300 connected to the housing 500, and the rotary positioning lock 5 disposed between the button support ring 400 and the housing 500, to lock the button support ring 400 in its current position after it rotates a predetermined angle relative to the inner ring 300.

[0062] In this embodiment, multiple rotary positioning locks 5 are arranged at circumferential intervals along the inner ring 300, such as at 30°, 45°, and 60°, which facilitates the real-time control of the rotation of the button pressing block 410 and makes the rotary button device more operable.

[0063] Specifically, the rotary positioning lock 5 includes a third elastic element 50 and a spherical pin 51. The third elastic element 50 is embedded in the inner ring 300, and the spherical pin 51 is connected to the third elastic element 50. When the inner ring 300 and the button support ring 400 are relatively stationary, at least a portion of the spherical pin 51 protrudes from the inner ring 300 and engages with the button support ring 400, which can brake the button support ring 400 and limit its rotational freedom. The button support ring 400 is provided with a locking position corresponding to the spherical pin 51. When the spherical pin 51 is aligned with the locking position, at least a portion of the spherical pin 51 is embedded in the locking position, which can more stably limit the relative movement between the inner ring 300 and the button support ring 400. When the button pressing block 410 is subjected to a rotational force, the inner ring 300 and the button support ring 400 rotate relative to each other. The button support ring 400 abuts against the ball pin 51, so that the ball pin 51 rotates and is pressed down. The third elastic element 50 is compressed until the ball pin 51 is flush with the inner ring 300, the ball pin 51 is misaligned with the locking position, and the ball pin 51 is no longer locked to the button support ring 400.

[0064] In another embodiment of this invention, the rotary positioning lock 5 includes a ratchet 52 and a pawl 53. One of the inner ring 300 and the button support ring 400 is provided with a ratchet 52, and the other is provided with a pawl 53, allowing the inner ring 300 and the button support ring 400 to rotate intermittently relative to each other. The pawl 53 can drive the ratchet 52 to move in one direction, locking the inner ring 300 and the button support ring 400 in the opposite direction, thus acting as a mechanical damper. To prevent jamming, a high-viscosity damping grease can be filled between the ratchet 52 and the pawl 53. When the inner ring 300 and the button support ring 400 rotate circumferentially, the viscous damping grease moves, generating a circumferential shear force, allowing the rotation to be slow and controllable at a certain speed.

[0065] In another embodiment of this invention, the rotary positioning lock 5 can also be positioned by friction damping force or by magnetic positioning. The same principle applies: the rotary positioning lock 5 is set at predetermined angles to cooperate with the locking position, which restricts the relative rotational freedom of the inner ring 300 and the button support ring 400. This allows the button support ring 400 and the button pressing block 410 to be briefly obstructed when they rotate to a predetermined angle, resulting in slow or stopped movement. As long as the operator increases the rotational force, the rotary positioning lock 5 can control the movement of the rotary button device, making it easier for the operator to operate quickly and efficiently.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
