Description

Technical Field

[0001] The invention relates to the technical field of machine tools, and in particular to a tracking type three-color warning lamp for machine tools. Background Art

[0002] Machine tool alarm lights generally have three states. The green light represents normal operation, the yellow light represents standby state, and the red light represents a fault. Therefore, when in use, different colors will be displayed in different states. However, since the volume of this type of alarm light is fixed, the three-divided color gamut causes the alarm display area to become smaller. For example, when the red light alarms, the red light area lights up, and the green and yellow areas remain off. Then the lit red light area only occupies one-third of the entire alarm light. Due to the particularity of the workshop environment and the small displayed alarm area, and because there is generally more than one machine tool, after the alarm light is on, it is easy to be blocked by other machine tools. This can easily lead to the staff's inability to notice the alarm status of the lamp body in time, causing more serious accidents. In addition, the current alarm lights are directly fixed and lack the necessary buffer structure. Once hit, the alarm light is easily damaged. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a tracking type three-color alarm light for machine tools, which can lift the three-color alarm light so that the lit three-color alarm light is staggered with the machine tool to avoid obstruction, and the flashing light can automatically find the surrounding staff and remind the staff by flashing the screen so that they can respond in time.

[0004] The present invention is achieved through the following technical solutions: a tracking type machine tool three-color alarm light, including an electric push rod and a three-color alarm light, a shell is installed on the bottom surface of the three-color alarm light, a control module is installed inside the shell, a 360° rotating automatic pan-tilt is installed on the bottom surface of the shell, a strobe light is installed on the rotating part of the automatic pan-tilt, a U-shaped plate is installed outside the strobe light, an infrared sensor is installed inside the U-shaped plate, the automatic pan-tilt is controlled by the infrared sensor and the control module, the electric push rod is arranged above the three-color alarm light, the piston rod of the electric push rod is installed on the top surface of the three-color alarm light through a connecting flange, an expansion alarm light is installed outside the electric push rod, and an elastic connector connected to the indoor ceiling is installed on the upper end of the electric push rod.

[0005] As a preferred technical solution, the expansion alarm light includes a fixing ring, a push switch and multiple light boards. The fixing ring is installed on the outside of the electric push rod. Multiple torsion spring hinges are installed on the outer ring surface of the fixing ring. The multiple torsion spring hinges are evenly distributed around the fixing ring. The upper ends of the light boards are installed on the other end of the torsion spring hinges. The top of the three-color alarm light shrinks inward to form an annular groove. A rubber ring is installed in the annular groove. The lower end of the light board is tilted against the outer ring surface of the rubber ring. A groove is provided on the bottom surface of the fixing ring. The push switch is installed in the groove. The pressing part of the push switch extends through the groove to the outside. The light boards are connected to the push switches through wires, and the light-emitting end faces of the light boards are all set outward.

[0006] As a preferred technical solution, the elastic connecting part includes a spring, a fixed rod and multiple blocking rods. The lower end of the spring is installed on the top surface of the electric push rod through a connecting flange, and the upper end of the spring is fixedly connected to the fixed rod through a connecting flange. The top surface of the fixed rod is installed with a fixing flange. The blocking rod is installed in an annular structure at the lower end of the fixed rod. The blocking rods are all arranged at an angle, and the lower ends of the blocking rods extend to the outside of the electric push rod. The outside of the blocking rods is wrapped with a rubber layer.

[0007] As a preferred technical solution, a wiring tube is installed on one side of the shell, the control module is a single-chip microcomputer installed on the PCBA board, and the wires connected to the PCBA board pass through the wiring tube and are connected to the strobe light.

[0008] As a preferred technical solution, a plurality of heat dissipation openings are provided on the outer wall surface of the shell.

[0009] As a preferred technical solution, the colors of the three-color warning light are yellow, green and red respectively, and a plurality of prisms are installed on the inner wall surface of the three-color warning light housing opposite to the red light.

[0010] As a preferred technical solution, a ring-shaped transparent protective film is attached to the outside of the three-color warning light.

[0011] The beneficial effects of the present invention are:

[0012] 1. After a fault alarm occurs, the electric push rod can lift the three-color alarm light upward, so that the three-color alarm light is misaligned with the surrounding machine tools, making it easier to see the three-color alarm light at a high place and increasing the warning effect;

[0013] 2. After the three-color warning light moves upward, it will push the light board outward, so that the light board opens in an umbrella shape. The illuminated light board increases the warning range, and the light-emitting end of the light board is set upward, which can form a bright area at the top, further increasing the warning effect;

[0014] 3. After the three-color alarm light is raised, the automatic pan-tilt can drive the strobe light to rotate 360°. The movement of the strobe light drives the infrared sensor. When the infrared sensor is facing the staff, the automatic pan-tilt will stop rotating, causing the strobe light to flash towards the staff, effectively reminding the staff to respond in time;

[0015] 4. After being hit, the device can bend with the spring as the center and provide a buffering effect through the spring, thereby increasing safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1 and Figure 2As shown, a tracking type machine tool three-color alarm light of the present invention comprises an electric push rod 6 and a three-color alarm light 1, a shell 2 is installed on the bottom surface of the three-color alarm light 1, a control module is installed inside the shell 2, a 360° rotating automatic pan-tilt head 3 is installed on the bottom surface of the shell 2, a strobe light 5 is installed on the rotating part of the automatic pan-tilt head 3, a U-shaped plate is installed outside the strobe light 5, an infrared sensor 5 is installed inside the U-shaped plate, the automatic pan-tilt head 3 is controlled by the infrared sensor and the control module, the electric push rod 6 is arranged above the three-color alarm light 1, the piston rod of the electric push rod 6 is installed on the top surface of the three-color alarm light 1 through a connecting flange, an expansion alarm light is installed outside the electric push rod 6, an elastic connector connected to the indoor ceiling is installed on the upper end of the electric push rod 6, and the electric push rod is also controlled by the control module.

[0024] In this embodiment, the expansion alarm light includes a fixing ring 7, a push switch 15 and a plurality of lamp boards 8. The fixing ring 7 is mounted on the outside of the electric push rod 6. A plurality of torsion spring hinges 16 are mounted on the outer ring surface of the fixing ring 7. The plurality of torsion spring hinges 16 are evenly distributed around the fixing ring 7. The upper ends of the lamp boards 8 are mounted on the other end of the torsion spring hinges. The top of the three-color alarm light 1 is reduced inward to form an annular groove. A rubber ring 17 is mounted in the annular groove. The lower end of the lamp board 8 is tilted against the outer ring surface of the rubber ring 17. A groove is provided on the bottom surface of the fixing ring 7. The push switch 15 is mounted in the groove. The pressing portion of the push switch 15 extends through the groove to the outside. The lamp boards 8 are connected to the push switch 15 through a wire. The light-emitting end surfaces of the lamp boards 8 are all arranged outward. The flexibility of the rubber ring avoids direct friction with the lamp board and avoids noise when the lamp board is pushed.

[0025] In this embodiment, the elastic connecting member includes a spring 11, a fixed rod 9 and a plurality of blocking rods 12. The lower end of the spring 11 is installed on the top surface of the electric push rod 6 through a connecting flange, and the upper end of the spring 11 is fixedly connected to the fixed rod 9 through a connecting flange. The top surface of the fixed rod 9 is provided with a fixing flange. The blocking rod 12 is installed at the lower end of the fixed rod 9 in an annular structure. The blocking rods 12 are all inclined. The lower ends of the blocking rods 12 extend to the outside of the electric push rod 6. The outside of the blocking rods 12 are wrapped with a rubber layer. After being hit, the three-color alarm light can rotate in the opposite direction with the spring as the center, offsetting part of the impact by moving, and further offsetting part of the impact by the elastic energy of the spring to increase safety. The rotation range of the fixed rod and the three-color alarm light is blocked by the blocking rod to avoid excessive rotation.

[0026] In this embodiment, a wiring tube 14 is installed on one side of the housing 2, and the control module is a single chip microcomputer installed on the PCBA board. The wires connected to the PCBA board pass through the wiring tube and are connected to the strobe light 4.

[0027] In this embodiment, a plurality of heat dissipation openings 13 are provided on the outer wall surface of the housing 2, and the heat inside the housing can be discharged through the heat dissipation openings.

[0028] In this embodiment, the colors of the three-color warning light 1 are yellow, green and red respectively. A plurality of prisms are installed on the inner wall surface of the shell of the three-color warning light 1 opposite to the red light. The emitted red light can be dispersed by the prisms, thereby causing it to be emitted in different directions, increasing the divergence angle of the red light to increase the warning range.

[0029] In this embodiment, a ring-shaped transparent protective film is attached to the outside of the three-color warning light 1, and the transparent protective film is disconnected in the middle, so the transparent protective film can be opened and wrapped around the outside of the three-color warning light, and can also be replaced. The transparent protective film can effectively prevent the three-color warning light from being scratched to ensure the brightness of the three-color warning light itself.

[0030] As attached Figure 3 As shown, after a fault occurs, the control module can control the electric push rod to retract the piston rod of the electric push rod. The movement of the piston rod drives the three-color alarm light, so that the three-color alarm light can rise and be misaligned with the surrounding machine tools, which makes it easier to see the three-color alarm light located at a high place, avoids obstruction of vision, and increases the warning effect; wherein, the movement of the three-color alarm light can push the light board outward, so that the light board opens in an umbrella shape. After the three-color alarm light moves to the highest point, the top of the three-color alarm light can squeeze the press switch, and the light board can be lit by pressing the switch. The lit light board increases the warning range, and the light-emitting end surface of the light board is arranged upward, which can form a bright area on the top, further increasing the warning effect;

[0031] Among them, the movement of the three-color alarm light drives the shell and the strobe light. After moving to a certain height, the automatic pan-tilt head will start, and the automatic pan-tilt head can drive the strobe light to rotate 360°. The movement of the strobe light drives the infrared sensor. After the infrared sensor is facing the staff, the infrared sensor can detect the staff and transmit the information to the control module. The automatic pan-tilt head will be stopped through the control module, and the strobe light will be started to flash towards the staff, effectively reminding the staff to respond in time.

[0032] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
