Description

Technical Field

[0001] This invention relates to the field of warning light technology, and specifically to a machine tool warning light. Background Technology

[0002] Machine tool warning lights generally have three states: green for normal operation, yellow for standby, and red for malfunction. Different colors are displayed depending on the state. However, because these warning lights have a fixed size, the three-part color gamut results in a small alarm display area. For example, when the red light is on, the red area is lit while the green and yellow areas remain off. The lit red area only occupies one-third of the entire warning light. Due to the specific environment of the workshop and the small alarm display area, it is easy for workers to fail to notice the alarm status in time, potentially leading to more serious accidents.

[0003] Furthermore, different factory environments present different usage requirements. For red lights, workers need to be able to quickly perceive the warning. Therefore, it's ideal to have a wide-ranging illumination area for easy observation when the light is red. However, if there are multiple devices or obstructions at similar heights to the warning light in the scene, even if the light is easily visible at close range, obstructions between the observation height and the warning light at a distance can still affect the line of sight. Therefore, there is an urgent need for a machine tool warning light that can expand the visual display area of ​​the alarm, provide auxiliary alarm methods, and is easy to store and transport. Summary of the Invention

[0004] In view of the prior art, the purpose of this invention is to provide a warning light that, through the cooperation of internal mechanical structure and electromagnetic control, achieves dynamic expansion of the red light display area in the alarm state, and, combined with laser projection and atomization auxiliary means, greatly improves the recognition and prompting effect of the alarm signal.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a machine tool warning light, comprising a lamp holder and a lamp tube, wherein the lamp holder is fixed to the surface of the machine tool, and the lamp tube is threadedly connected to the lamp holder; the lamp tube includes a refraction lamp tube, a lamp assembly, and a bracket; the refraction lamp tube includes a mounting cylinder, several light-transmitting cylinders, and a top cover; the lower end of the mounting cylinder is connected to the lamp holder, and the upper end is connected to the light-transmitting cylinders; the top cover is installed on the upper opening of the light-transmitting cylinders to close the refraction lamp tubes; the lower end of the bracket is fixed inside the mounting cylinder and includes a sub-frame and a mounting plate corresponding to the light-transmitting cylinders; the lamp assembly includes... The system includes a light control board and a bulb holder fixed on a bracket. The bulb holder is located on a mounting plate and is connected to a bulb assembly. The refracting lamp tube also contains a three-color paper tube, which includes three-color plastic film, an electromagnet assembly, and a magnetic counterweight ring. The magnetic counterweight ring is located in the middle of the three-color plastic film. A pure red film is placed on the upper side of the magnetic counterweight ring, and a red, yellow, and green film is placed on the lower side. The upper end of the magnetic counterweight ring is attracted to the iron core of the electromagnet assembly and can detach from the attraction due to the magnetic repulsion generated by the electromagnet assembly when the red light is triggered.

[0006] As a further feature of the above scheme, the light-transmitting tube is provided with axial grooves and circumferential grooves on its inner and outer outer walls, respectively.

[0007] As a further feature of the above solution, the bracket is provided with a number of screw holes, which are used for bolt positioning and fixing of the sub-frame and the mounting plate.

[0008] As a further feature of the above solution, the top cover is also equipped with a laser light assembly that is electrically connected to the light assembly and is synchronously triggered by a red light signal. The laser light assembly is used to shine upwards when the red light is on.

[0009] As a further feature of the above solution, the top cover is also equipped with an atomizer with a water tank, which is used to spray water vapor upwards. The top cover is also equipped with a blower motor, which is used to create airflow on the side of the atomizer to push the water vapor upwards.

[0010] As a further feature of the above solution, the lamp control board is placed inside the mounting cylinder, and a hollow cylinder is provided between the mounting cylinder and the refracting lamp cylinder. A buzzer is provided at the upper end of the lamp control board at the hollow cylinder.

[0011] As a further provision of the above solution, the lamp holder includes a hollow spiral tube threaded to the bottom of the lamp tube and a mounting base. The hollow spiral tube is pivotally connected to the mounting base. A locking rod is provided in the mounting base. The locking rod is provided with a return spring. A limiting groove is provided at the bottom of the hollow spiral tube. The return spring is used to push the locking rod into the limiting groove. Under the pressure of an external force, the locking rod is compressed and contacts the limiting groove.

[0012] Beneficial effects: This invention, by setting a dropable and unfoldable pure red film, can quickly expand the red warning area when the red light fault alarm is triggered, greatly improving the recognition of the red alarm signal and preventing staff from missing the alarm due to a small warning area, thus reducing the risk of accidents. At the same time, when the red light is triggered, the laser light assembly on the top cover is activated simultaneously, forming a conspicuous light column with the atomizer. Even if the warning light body is blocked by surrounding equipment, the light column above can still allow staff to quickly locate the faulty machine tool, further improving the warning effect. The lamp holder has an adjustable swing angle, which makes it easy to adjust the lamp tube orientation according to the installation environment and also facilitates equipment transportation and storage. The buzzer set in the hollow cylinder can further enhance the alarm effect through sound prompts. The combination of multiple warnings greatly improves the reliability of machine tool fault early warning. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0018] like Figure 1-3The machine tool warning light shown includes a lamp holder 1 and a lamp tube 2. The lamp holder 1 is fixed to the surface of the machine tool, and the lamp tube 2 is threaded onto the lamp holder 1. The lamp tube 2 includes a refraction lamp tube 21, a lamp assembly 22, and a bracket 23. The refraction lamp tube 21 includes a mounting cylinder 211, several light-transmitting cylinders 212, and a top cover 213. The lower end of the mounting cylinder 211 is connected to the lamp holder 1, and the upper end is connected to the light-transmitting cylinders 212. The top cover 213 is installed on the upper opening of the light-transmitting cylinders 212 to close the refraction lamp tube 21. The lower end of the bracket 23 is fixed inside the mounting cylinder 211 and includes a sub-frame 231 corresponding to the light-transmitting cylinders 212 and a mounting plate 232. The lamp assembly 22 includes components fixed to the bracket. The lamp control board 221 and the bulb holder 222 on the mounting plate 232 are connected to the bulb assembly 223. The refracting lamp tube 21 is also provided with a three-color paper tube 3. The three-color paper tube 3 includes a three-color plastic film 31, an electromagnet assembly 32 and a magnetic counterweight ring 33. The magnetic counterweight ring 33 is located in the middle of the three-color plastic film 31. A pure red film 311 is provided on the upper side of the magnetic counterweight ring 33, and a red, yellow and green three-color film 312 is provided on the lower side. The upper end of the magnetic counterweight ring 33 is attracted to the iron core 321 of the electromagnet assembly 32, and can be released from attraction by the magnetic repulsion generated by the electromagnet assembly 32 when the red light is triggered.

[0019] With the above structural setup, when the machine tool warning light is in normal operation or standby mode, it is held by the magnetic counterweight ring 33 adsorbed onto the iron core 321, compressing the pure red film 311 of the three-color paper tube 3, so that the red, yellow and green three-color film 312 on the lower side is held in the position of the light-transmitting tube 212. At this time, the three layers of light-transmitting tube 212 correspond to the red, yellow and green colors respectively. When the internal bulb assembly 223 is lit, the corresponding color is shone through the three-color paper tube 3 to display the corresponding status.

[0020] When the red light fault alarm signal is triggered, the top red light lights up, and at the same time the electromagnet component 32 is energized. The magnetic counterweight ring 33, which was originally attached to the iron core 321, is detached from the magnetic field due to the repulsive magnetic force. Under its own gravity, it moves the pure red film 311 downward and stretches to cover the entire area of ​​the light-transmitting tube 212, expanding the red light display area that originally only occupied one-third of the tube to the entire light-transmitting tube. It also lights up the two lower lights together, making the entire refracting lamp tube 21 emit red light, which greatly improves the visual display area of ​​the red light alarm. This makes it easier for workers in the workshop to notice the alarm signal quickly and avoid missing the alarm prompt due to the small display area.

[0021] As a further feature of the above scheme, the light-transmitting tube 212 has axial grooves 219 and circumferential grooves 218 on its inner and outer walls, respectively. After the light passes through the tricolor paper tube 3, it first contacts the axial groove 219 to form refraction. After the refracted light passes through, it is refracted a second time on the outer circumferential groove 218. Combined with the bulb assembly 223 with circumferential LED beads that is electrically connected to the bulb holder 222, the light is emitted in all directions.

[0022] As a further feature of the above solution, the bracket 23 is provided with a plurality of screw holes 233. The screw holes 233 are used for bolt positioning and fixing of the sub-frame 231 and the mounting plate 232. In use, the machine tool warning light of the present invention can be set with two or three layers according to the usage requirements. The bracket 23 is configured according to the usage requirements. During assembly, the screw holes 233 are used as the connection and fixing between two sub-frames 231 to stack multiple sub-frames 231 to achieve multi-layer installation. The mounting plate 232 is also fixed to the lower half of each sub-frame 231 using screw holes 233 for the installation of the bulb holder 222. The wires for the bulb assembly 223 can be routed along the bracket 23.

[0023] As a further provision of the above solution, the top cover 213 is also provided with a laser light assembly 24 that is electrically connected to the light assembly 22 and is synchronously triggered by a red light signal. The laser light assembly 24 is used to illuminate upwards when the red light is on. The top cover 213 is also provided with an atomizer 25 with a water tank. The atomizer 25 is used to spray water vapor upwards through its opening. The top cover 213 is also provided with a blower motor, which is used to create airflow on the side of the atomizer 25 to push the water vapor upwards.

[0024] The warning light of this invention takes into account the installation location and the obstruction caused by surrounding equipment, which may lead to poor observation of the red indicator of the warning light itself. Therefore, when the alarm red light is triggered, the laser light assembly 24 is simultaneously activated to illuminate the laser light column at a slight tilt angle towards the workshop ceiling, making it easier for workers to identify the triggered machine tool. In addition, the invention further incorporates an auxiliary unit atomizer 25, which uses atomized water vapor driven by a blower motor to make the laser light column more conspicuous and improve the warning effect.

[0025] As a further feature of the above scheme, the lamp control board 221 is placed inside the mounting cylinder 211, and a hollow cylinder 216 is provided between the mounting cylinder 211 and the refracting lamp cylinder 21. A buzzer 217 is provided at the upper end of the lamp control board 221 at the hollow cylinder 216.

[0026] As a further provision of the above scheme, the lamp holder 1 includes a hollow screw tube 12 threadedly connected to the bottom of the lamp tube 2 and a mounting base 11. The hollow screw tube 12 is pivotally connected to the mounting base 11. A locking rod 13 is provided in the mounting base 11. The locking rod 13 is provided with a return spring 14. A limiting groove 15 is provided at the bottom of the hollow screw tube 12. The return spring 14 is used to push the locking rod 13 into the limiting groove 15. When the locking rod 13 is pressed by an external force, the return spring 14 is compressed and contacts the limiting position. By pressing the locking rod 13, the locking rod 13 can move inward and pop out from the limiting groove 15. At this time, the hollow screw tube 12 swings relative to the mounting base 11, so that the lamp tube 2 can swing and fit against the machine tool surface for easy transportation. After releasing the press, the lamp tube 2 swings and fits against the machine tool surface to form a limiting position. The swing angle is 90°. Pressing again and swinging in the opposite direction can make it vertical.

[0027] As mentioned above, refer to Figure 1 and Figure 2 As shown, during actual assembly, the bracket 23 is first fixed inside the mounting cylinder 211 through the screw hole 233, the sub-frames 231 are connected and fixed together, the bulb holder 222 is fixed to the lower half of the sub-frame 231 through the screw hole 233, and the wires of the bulb assembly 223 are routed on the bracket 23.

[0028] The light control board 221 is placed inside the mounting cylinder 211. A hollow cylinder 216 and a buzzer 217 are provided between the mounting cylinder 211 and the reflective lamp cylinder 21 to give a simultaneous audible warning when the red light alarms.

[0029] The three-color paper tube 3 is installed inside the light-transmitting tube 212. In the initial state, the magnetic counterweight ring 33 is attracted to the iron core 321 of the electromagnet assembly 32 set inside the top cover 213, the pure red film 311 is compressed on top, and the red, yellow and green three-color films 312 cover the corresponding positions of the light-transmitting tube.

[0030] When the machine tool system issues a fault signal, the lighting control board 221 not only controls the top red light to illuminate, but also supplies power to the electromagnet assembly 32. When energized, the electromagnet assembly 32 generates a magnetic force that repels the magnetic counterweight ring 33. The magnetic counterweight ring 33 detaches from the iron core 321 and falls naturally under gravity, stretching the upper pure red film 311 to completely cover all the light-transmitting tubes 212, while simultaneously pressing the red, yellow, and green films 312 to the bottom (resetting only requires de-energizing the electromagnet assembly 32, removing the lamp tube 2, inverting it, and allowing the magnetic counterweight ring 33 to reattach to the iron core 321). Simultaneously, when the fault signal is triggered, the lower-layer bulb assembly 223 is also illuminated, and the entire refracting lamp tube 21 displays a high-brightness red warning light.

[0031] Furthermore, in a further design, when a fault signal is triggered, the laser light assembly 24 inside the top cover 213 will be powered on, projecting a red laser beam onto the ceiling. Additionally, the atomizer 25 sprays fine water mist, and the airflow generated by the blower motor pushes the water mist upwards. The water mist particles make the beam clearly visible in the air, facilitating quick location of the faulty equipment by personnel at a distance. It is worth noting that the total amount of water mist sprayed by the atomizer 25 is relatively small and generally will not affect the machine tool. In locations or with machine tools where humidity is a concern, the atomizer 25 can be used without filling it with water; only the laser light assembly 24 needs to be used.

[0032] When the equipment is being transported or idle, the operator simply needs to press the locking lever 13 inside the mounting base 11, causing it to compress the return spring 14 and move inward from the limiting groove 15. Then, the lamp tube 2 is swung downwards 90° to fit against the machine tool surface, the locking lever 13 is released, and under the action of the return spring 14, the locking lever re-locks into a new limiting position (or is held in place by friction / locking structure), completing the folding and storage. When needed, the locking lever 13 is pressed again to release the limiting position, and the lamp tube 2 is swung in the opposite direction to a vertical position.

[0033] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
