Description

Technical Field

[0001] The utility model relates to the technical field of light source detection, in particular to an automatic protection light source capable of setting a temperature value. Background Art

[0002] As the speed of automated inspection increases, the brightness of the inspection light source has also been improved. Existing line scan light sources generally have cooling methods such as air cooling, gas cooling and water cooling. Among them, although air cooling and water cooling have better heat dissipation effects, some factories do not have this mode and are not suitable for installing air cooling and water cooling devices. Therefore, traditional fan cooling is more suitable.

[0003] However, fan cooling, as a relatively good heat dissipation mode for detection light sources, is easily affected by hardware, namely fan failure, which leads to poor heat dissipation of LED light sources and even serious light decay or burning of LED lamp beads. When the fan fails, it is usually necessary to replace the fan and new LED lamp beads at the same time, which has high maintenance costs and certain usage defects. Therefore, we propose an automatic protection light source with a settable temperature value to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide an automatic protection light source with a settable temperature value, so as to solve the problem that the fan heat dissipation detection light source proposed in the above background technology is easily affected by hardware, i.e. fan failure, resulting in poor heat dissipation of the LED light source, and even serious light decay or burning of the LED lamp beads. When the fan fails, it is usually necessary to replace the fan and new LED lamp beads at the same time, and the maintenance cost is high.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an automatic protection light source capable of setting a temperature value, comprising an LED lamp bead, a temperature sensor being provided on one side of the LED lamp bead, and a heat conducting plate being provided above the LED lamp bead and the temperature sensor, a temperature controller and a temperature display being fixedly mounted on the outer end surface of the heat conducting plate, heat sinks being evenly distributed on the upper end of the heat conducting plate, and a mounting bracket being provided on the upper end of the heat sink;

[0006] A motor is arranged above the mounting frame, and a fan is fixedly installed at the lower end of the motor, a support assembly is arranged on the outside of the motor, a focusing cylindrical lens is arranged below the LED lamp beads, and a support frame is arranged on the outside of the focusing cylindrical lens, and a diffusion plate is arranged below the focusing cylindrical lens.

[0007] As an optimal technical solution of the present invention, a first fixing frame and a second fixing frame for fixing the heat sink are symmetrically arranged on the upper and lower sides of the outer end surface of the heat sink, and the first fixing frame is fixedly connected to the lower end of the mounting frame, and the second fixing frame is fixedly connected to the upper end of the heat conducting plate.

[0008] As a preferred technical solution of the present invention, the support assembly includes a connecting frame arranged on the outside of the motor, and connecting rods are distributed at equal angles between the connecting frame and the motor to fix the connecting frame and the motor.

[0009] As a preferred technical solution of the present invention, a support rod is fixedly connected to the end face of the connecting frame close to the mounting frame, and the support rod is connected to the mounting frame through a bolt structure and plays a supporting role for the connecting frame and the motor.

[0010] As a preferred technical solution of the present invention, the support frame is symmetrically arranged on both sides of the focusing cylindrical lens, and the top end of the support frame is fixedly connected to the heat conducting plate through a bolt structure and plays a supporting role for the focusing cylindrical lens.

[0011] As an optimal technical solution of the present invention, the lower end of the support frame is bent, and connecting blocks that support the diffuser are symmetrically provided at both ends of the diffuser, and the diffuser is overlapped on the lower end of the support frame through the connecting blocks.

[0012] As a preferred technical solution of the present invention, the cross section of the connecting block along the axis of the focusing cylindrical lens is arranged in an "L" shape, and the connecting block is slidably connected to the support frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the automatic protection light source with a settable temperature value has a good heat dissipation effect, and at the same time, the temperature sensor can output an analog signal to the temperature controller in real time, and the temperature display can display the light source temperature in real time, which can protect the LED lamp beads from burning out due to excessive temperature, and the cooling fan can be easily disassembled and repaired, thereby reducing maintenance costs;

[0014] 1. The temperature sensor can output an analog signal to the temperature controller in real time. At the same time, the temperature display can show the measured temperature in real time. The temperature controller can protect the LED lamp beads by setting the upper limit of temperature protection. When the temperature reaches the upper limit set by the temperature controller, the temperature controller will automatically cut off the input power of the LED lamp beads, thereby protecting the LED lamp beads from burning out due to excessive temperature.

[0015] 2. A heat conducting plate and a heat sink are provided on the upper end of the LED lamp bead, and a fan is provided above the heat sink to dissipate heat from the LED lamp bead through the heat sink. The fan is driven by a motor to blow air to the heat sink and the heat conducting plate, thereby increasing the heat dissipation efficiency of the heat sink and achieving good heat dissipation effect.

[0016] 3. A support assembly is set on the outside of the motor. Since the fan is easily affected by the external environment, such as temperature, dust, etc., or its own quality problems, it may malfunction. When the fan needs to be replaced, you only need to disassemble the support rod and the mounting bracket to remove the entire support assembly, and then you can repair and replace the motor and fan, which is convenient to operate.
