[0002] A lot of dust will be generated on the laser table for screen printing of solar cells. Usually, a dust removal device needs to be installed on the laser table to absorb the dust. At present, the air inlet of the dust removal device is usually a trumpet-shaped open-type. This trumpet-shaped open-type dust removal device has the following disadvantages.

[0003] The dust removal effect is poor, and a large amount of dust will accumulate on the inner wall of the air inlet, which will not only seriously affect the operation of electrical components, but also affect the hygiene of the machine, and then affect the environmental hygiene of the solar cell workshop and affect the quality of the battery cells.

[0004] 1. The air inlet opening cannot be adjusted in size, and cannot be adjusted for different battery cells, dust removal heights, and suction requirements. Dust removal can only be passive;

[0005] 2. The opening cannot be closed. When the dust collector is backflushing, a reverse airflow will occur, causing the dust inside the pipe to recoil and spread on the machine.

[0006] 3. There is a large amount of dust accumulated on the inner wall of the bell mouth, which cannot be taken away by the wind in the dust collector and needs to be wiped manually, which is time-consuming and laborious. Utility Model Content

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] A self-cleaning dust removal port device, such as Figure 1-Figure 2As shown, it includes a main body 1, a valve device 2, an air duct pipe 3, and a PLC controller. The valve device 2 is arranged on the air inlet of the main body 1 and is slidably connected thereto. The function of the valve device 2 is to seal the air inlet of the main body 1 by moving the valve device 2 to form a closed space. The air duct pipe 3 is arranged on the valve device 2, and the air duct pipe 3 and the air inlet of the main body 1 are docked. The docking can be understood as when the valve device 2 seals the air inlet of the main body 1, air can be blown into the main body 1 through the air duct pipe 3 to clean the dust. The valve device 2 and the PLC controller are connected by signal. The operation of the valve device 2 is controlled by the PLC, so that the valve device 2 and other external components are linked. When a considerable amount of dust accumulates in the main body 1, the PLC controller controls the valve device 2 to close the air inlet of the main body 1, and then blows air into the main body 1 through the air duct pipe 3 to clean the dust in the main body 1.

[0022] The main body 1 includes an air duct 11 and a bell tube 12. The bell tube 12 is a pipe with a larger opening at one end and a smaller opening at the other end. The end with the larger opening is the air inlet, and air enters from the end with the larger bell mouth. Its advantages are that the incoming air is streamlined, the resistance is reduced, and the efficiency at the fan inlet is improved. It can also reduce the resistance and noise generation, thereby reducing the noise of the entire system. The air duct 11 is connected to the end of the bell tube 12 with the smaller opening and is fixedly connected to it. The valve device 2 is arranged on the end of the bell tube 12 with the larger opening and is slidably connected to it.

[0023] like Figure 3-Figure 4 As shown, the end of the trumpet tube 12 with a larger opening is provided with docking grooves 13 on its left and right sides and the lower side, and the valve device 2 is slidably connected with the trumpet tube 12 in the docking grooves 13 on the left and right sides, that is, the three sides of the trumpet tube 12 are provided with docking grooves 13, and the function of the docking grooves 13 is to improve the sealing between the valve device 2 and the body 1, and prevent the dust from flying out of the air duct when blowing. A guide groove 14 is provided on the upper side of the end of the trumpet tube 12 with a larger opening, and the valve device and the guide groove are docked. The setting of the guide groove 14 makes it more convenient to re-enter the valve device 2 after the trumpet tube 12 is separated.

[0024] The valve device 2 includes a bracket 21, a cylinder 22, a connecting rod 23, a door panel 24, a guide rail 25, and a limit screw 26. The bracket 21 is a frame structure. The bracket 21 is arranged above the body 1 and is fixedly connected thereto. The cylinder 22 is arranged above the bracket 21 and is fixedly connected thereto. The cylinder 22 is a power source. A vertically arranged guide rail 25 is fixedly arranged on the bracket 21. The door panel 24 is slidably connected to the guide rail 25. The door panel 24 is connected to the air inlet of the body 1. The vertically arranged guide rail 25 guides the door panel 24 slides in the vertical direction. When it slides to the top, the air inlet is fully opened. When it slides to the bottom, the air inlet is closed. The cylinder 22 is connected to the door panel 24 through the connecting rod 23. The cylinder 22 moves the door panel 24 up and down. A limit screw 26 is provided above the bracket 21. The limit screw 26 is connected to the door panel 24. The limit screw 26 is adjusted to control the movement of the door panel 24 within a specified range, and finally the size of the air inlet is controlled. The cylinder 22 is electrically connected to the PLC controller. Two guide rails 25 are provided. The two guide rails 25 are provided on both sides of the door panel 24 symmetrically. The two guide rails 25 improve the stability of the door panel.

[0025] The air duct pipe 3 is arranged around the valve device 2. Specifically, a circle of mounting grooves is provided on the door panel 24. The air duct pipe 3 is installed in the mounting groove. The shape of the mounting groove is the same as the shape of the air outlet of the main body 1. The air duct pipe 3 is connected to the air inlet of the main body 1. The air duct pipe 3 is arranged in a circle to blow air circumferentially to the inner wall of the main body 1. When the door panel 24 is completely closed, the air duct pipe 3 just blows air to the inner wall around the air outlet of the main body 1 to clean the dust on the inner wall more cleanly.

[0026] The principle of the utility model is to clean the dust inside the main body by setting a valve device and an air duct and linking them with other equipment under the control of a PLC controller to prevent the dust inside the main body from rebounding out. The size of the air inlet of the main body can be controlled by the valve device to adapt to a variety of usage scenarios. The docking groove and the guide groove are set to improve the convenience of using the door panel.
