Description

Technical Field

[0001] This utility model relates to the field of safety light curtain technology, specifically a safety light curtain fault alarm device. Background Technology

[0002] Safety light curtains are an important photoelectric safety protection device, widely used in modern factories, especially on potentially dangerous mechanical equipment such as stamping machinery and shearing equipment, to protect the personal safety of workers. With the new era's industrial system having zero tolerance for safety accidents, safety light curtains are receiving increasing attention.

[0003] Currently, when safety light curtain fault alarm devices are used in dusty or dark and humid industrial environments, dust or water droplets can accumulate on the mirror surface of the emitter or receiver, causing the safety light curtain to malfunction and trigger an ineffective alarm, thus reducing the accuracy of the fault alarm. Utility Model Content

[0004] The purpose of this invention is to provide a safety light curtain fault alarm device to solve the problem mentioned in the background art that when encountering dusty or dark and humid industrial environments, the mirror surface of the light emitter or light receiver becomes contaminated with dust or water droplets, which can cause the safety light curtain to malfunction and fail to alarm, thus reducing the accuracy of the fault alarm. To achieve the above objectives, this utility model provides the following technical solution: a safety light curtain fault alarm device, comprising a housing, a cleaning component provided on one side of the housing, the cleaning component including a rotary motor, the rotary motor being fixedly connected inside the housing, a threaded rod being fixedly connected to the transmission end of the rotary motor, a slider one being movably connected to the side surface of the threaded rod, a threaded groove being formed inside the slider one, a vertical rod being movably connected to the bottom of the slider one, a cleaning cylinder being fixedly connected to the side surface of the vertical rod, a slider two being movably connected to the bottom end of the cleaning cylinder, a fixed rod being movably connected to the inside of the slider two, and grooves being formed on opposite inner walls of the housing, with the fixed rod being fixedly connected to one inner wall of the groove. This safety light curtain fault alarm device, by adding a cleaning component, uses grooves to conceal the cleaning cylinder, the rotary motor drives the threaded rod to rotate, thereby driving the slider one to rotate through the threaded groove, and because the slider one is connected to the bottom slider two through the vertical rod, and the slider two is limited by the fixed rod to form a limit, the slider one can only move in the axial direction of the threaded rod, thereby driving the cleaning cylinder to clean the mirror surface, preventing dust or water droplets from adhering to the mirror surface and improving the accuracy of the fault alarm.

[0005] More preferably, the interior of the housing is provided with a heat dissipation component, which includes heat dissipation slots. Several heat dissipation slots are opened on the opposite side of the housing. A fan is fixedly connected inside the heat dissipation slot, and a protective net is fixedly connected to one side of the heat dissipation slot.

[0006] More preferably, a rotating assembly is provided on one side of the housing. The rotating assembly includes a rotating groove, which is formed on one side of the housing. A rotating shaft is movably connected to the inner wall of one side of the rotating groove. A rotating block is fixedly connected to the other end of the rotating shaft. An anti-slip pad is fixedly connected to the bottom of the rotating block. This type of safety light curtain fault alarm device, by adding the rotating assembly, allows the rotating block to flip in the rotating groove via the rotating shaft. The anti-slip pad used after the housing is installed can be used to support the bottom to increase friction and provide some support, thereby improving stability.

[0007] More preferably, a protective shell is fixedly connected to one side of the housing, and a motherboard is fixedly connected to the inner wall of one side of the housing.

[0008] More preferably, a plurality of light emitters are fixedly connected to one side of the motherboard, and a buzzer module is fixedly connected to the other side of the motherboard.

[0009] More preferably, a connector is fixedly connected to the bottom of the housing, and a light-receiving element is provided on one side of the housing.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In this invention, the safety light curtain fault alarm device incorporates a cleaning component. A groove is used to conceal the cleaning cylinder. A rotating motor drives a threaded rod to rotate, which in turn drives a slider to rotate through the threaded groove. Since slider one is connected to a bottom slider two via a vertical rod, and slider two is restricted by a fixed rod, slider one can only move along the axis of the threaded rod, thereby driving the cleaning cylinder to clean the mirror surface, preventing dust or water droplets from adhering to the mirror surface and improving the accuracy of the fault alarm.

[0012] In this utility model, the safety light curtain fault alarm device adds a rotating component. The rotating block flips in the rotating groove through the rotating shaft. It can be used in conjunction with the anti-slip pad for bottom support after the box is installed to increase friction and provide some support to improve stability. Attached Figure Description

Grooves 209 are provided on the inner walls of opposite sides of the housing 1, and the fixed rod 208 is fixedly connected to the inner wall of one side of the groove 209.

[0022] In this embodiment, as Figure 1 and Figure 5 As shown, a heat dissipation component 3 is provided inside the housing 1. The heat dissipation component 3 includes heat dissipation slots 301. Several heat dissipation slots 301 are opened on the opposite side of the housing 1. A fan 302 is fixedly connected inside the heat dissipation slots 301. A protective net 303 is fixedly connected to one side of the heat dissipation slots 301.

[0023] In this embodiment, as Figure 1 and Figure 6 As shown, a rotating assembly 4 is provided on one side of the housing 1.
