Problems solved by technology
When LEDs are used as array display and display devices, due to the sensitivity of the human eye to color wavelengths and brightness, unevenness will occur with unsorted LEDs, which will affect people's visual effects
The unevenness of wavelength and brightness will give people an uncomfortable feeling
This is what all LED display manufacturers are unwilling to see, and it is also unacceptable to people.

Embodiment Construction
[0022] Examples such as figure 1 , figure 2 , image 3 and Figure 4 Commonly shown is a dilator main body with a threaded propelling device. The dilator main body 1 is fixedly mounted with a threaded propelling device, and the threaded propelling device includes a fixed seat 2 and a cylinder body 6 fixed together. The screw propelling device is fixed on the dilator main body 1 through the fixing seat 2 and or the cylinder body 6 .
[0023] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown together, the threaded propulsion device includes a fixed seat 2 and a cylinder block 6 fixed together. A cavity 7 is provided on the fixed seat 2 , and an air intake joint 16 is installed on the cylinder body 6 , and the air intake joint 16 communicates with the cavity 7 . The cavity 7 is provided with a slidable cylinder piston 10 , one end of the cylinder piston 10 is located in the cavity 7 , and the other end is located outside the cylinder body 6 . The end of the...

The invention relates to a thread propulsion device and an expander main body with the same. The thread propulsion device comprises a fixed seat and a cylinder body which are fixed together, wherein acavity body is formed in the fixed seat, a cylinder piston capable of sliding is arranged in the cavity body, one end of the cylinder piston stretches out of the cylinder body and the end part is connected with a piston rod, a connection shaft is arranged on the cylinder piston, and the connection shaft and the piston rod are located outside the cylinder body; a bearing is installed on the connection shaft; and a pressure spring installation chamber is formed on the fixed seat, one end of a pressure spring is installed in the pressure spring installation chamber, and the other end of the pressure spring sleeves the piston rod. According to the thread propulsion device and the expander main body with the same, locking and unlocking for a lower body of an expander are realized by driving the bearing to move through the piston rod and pushing a locking head on an installation seat; and the thread propulsion device has the advantages of being simple in structure, convenient to operate, less in wear and capable of automatically returning the piston rod, facilitating to realizing automatic control, and the like.
Description
technical field [0001] The invention relates to a thread propulsion device, which belongs to the technical field of LED chip sorting. Background technique [0002] The human eye has a very high resolution of the color and brightness of light, and is especially sensitive to color differences and changes. In the early days, because LEDs were mainly used as indication or display lights, and generally appeared as a single device, the requirements for the sorting of their wavelengths and the control of brightness were not high. However, with the continuous improvement of the efficiency and brightness of the LDE, its application range is becoming wider and wider. When LED is used as an array display and display device, due to the sensitivity of the human eye to color wavelength and brightness, unevenness will occur with unsorted LEDs, which will affect people's visual effects. The unevenness of wavelength and brightness will give people an uncomfortable feeling. This is what al...
