[0071] The upper air inlet seat 121 of the embodiments of the present application is composed of the air inlet pipe 123 and the dust adsorption pipe 124. The air inlet pipe 123 and the dust adsorption pipe 124 are not connected with each other. The bottom of the air inlet pipe 123 is flat and has the air inlet channel 127. The flat bottom of the air inlet pipe 123 is used to connect the lower blowing air head 122 and make the air inlet channel 127 and the lower blowing air head 122 connected with each other.

[0072] The air inlet pipe 123 and the dust adsorption pipe 124 are arranged in a horizontal direction inside the blowing dust cover 110, so that the height dimension of the blowing dust cover 110 is smaller and the high space occupation is reduced. One end of the blowing dust cover 110 is used to arrange a quick connector connected with the compressed gas inlet 125. The other end of the blowing dust cover 110 is used to arrange a steel wire hose 143 connected with the vacuum adsorption interface 142.

[0073] In some optional embodiments, referring to FIGS. 1, 2 and 3, the panel carrier surface blowing and adsorbing cleaning mechanism provided by the embodiments of the present application comprises an upper air inlet seat 121, a lower blowing air head 122 and a blowing dust cover 110. Figures 3 to 5As shown, the surface blowing and adsorbing cleaning mechanism of the panel carrier provided by the embodiment of the application has a side wall of the dust adsorbing pipe 124 that is attached to and fixedly connected with the inner wall of the blowing dust cover 110. The width of the air inlet pipe 123 is smaller than the width of the dust adsorbing pipe 124, and a lower adsorbing passage 113 is formed between the side wall of the air inlet pipe 123 and the inner wall of the blowing dust cover 110.

[0074] The cross sections of the dust adsorbing pipe 124 and the blowing dust cover 110 of the embodiment of the application are both "F" shaped structures. The side wall of the dust adsorbing pipe 124 is attached to and fixedly connected with the inner wall of the blowing dust cover 110, so that the connection between the dust adsorbing pipe 124 and the blowing dust cover 110 is sealed. Thus, the compressed gas and dust in the blowing dust cover 110 can only be discharged out of the blowing dust cover 110 from the dust adsorbing port 126.

[0075] The width of the air inlet pipe 123 is smaller than the width of the dust adsorbing pipe 124, so that a lower adsorbing passage 113 is formed between the side wall of the air inlet pipe 123 and the inner wall of the blowing dust cover 110. The lower adsorbing passage 113 is in communication with the upper adsorbing passage 112, so that the compressed gas and dust of the dust suction port 111 are sequentially discharged from the lower adsorbing passage 113, the upper adsorbing passage 112, the dust adsorbing port 126, the suction hole 141, the vacuum adsorbing interface 142 and the steel wire hose 143.

[0076] In some optional embodiments, referring to Figure 6 and Figure 7 As shown, the surface blowing and adsorbing cleaning mechanism of the panel carrier provided by the embodiment of the application has a lower blowing air head 122 that is in a long strip structure. An upper long strip groove 128 is formed in the upper surface of the lower blowing air head 122. A plurality of air blowing holes 129 are formed in the bottom of the upper long strip groove 128 and are arranged at intervals along the length direction of the upper long strip groove 128. A lower long strip groove that is in communication with the plurality of air blowing holes 129 is formed in the lower surface of the lower blowing air head 122. The width of the lower long strip groove gradually increases away from the air blowing holes 129.

[0077] The lower blowing air head 122 of the embodiment of the application is in a long strip structure, and the length of the lower blowing air head 122 is used to cover the width of the panel carrier, so that the lower blowing air head 122 has a wider coverage area when it is used to clean the surface of the panel carrier. The upper long strip groove 128 of the lower blowing air head 122 is used to communicate with the air inlet passage 127, and the plurality of air blowing holes 129 inside the upper long strip groove 128 are used to uniformly blow the compressed gas in different zones, so that the air pressure of the airflow blown to the panel carrier is the same, and stubborn stains in different areas of the panel carrier can be quickly removed. The width of the lower long strip groove gradually increases away from the air blowing holes 129, so that the compressed gas blown by the plurality of air blowing holes 129 is guided and diffused.

[0078] In some alternative embodiments, referring to Figs. 1-3, the panel carrier surface blowing and adsorbing cleaning mechanism provided by the embodiments of the present application comprises a mounting plate 210, a height adjustment plate 220 connected to the mounting plate 210, a fixed plate 222 vertically connected to the height adjustment plate 220, and a blowing and dust collecting cover 110 fixedly connected to the fixed plate 222.

[0079] The vertical adjustment mechanism 230 comprises a fixed block 231 fixed to the top of the mounting plate 210, an adjustment screw 232 threadedly connected to the height adjustment plate 220 and rotatably connected to the fixed block 231, and a top block 233 fixed to the height adjustment plate 220, and a longitudinal thousandth knob 234 fixedly connected to the bottom of the top block 233 on the mounting plate 210.

[0080] The mounting plate 210 and the height adjustment plate 220 are connected by bolts, wherein the mounting plate 210 is provided with a threaded hole 211 for connecting the height adjustment plate 220, and the height adjustment plate 220 is provided with an elongated hole 221 matched with the threaded hole 211, and the height of the height adjustment plate 220 relative to the mounting plate 210 can be adjusted through the elongated hole 221. The adjustment screw 232 is rotatably connected to the fixed block 231 and threadedly connected to the height adjustment plate 220, and is used for vertically coarsely adjusting the height of the height adjustment plate 220. The longitudinal thousandth knob 234 is used for finely adjusting the height of the height adjustment plate 220.

[0081] Working principle

[0082] The panel carrier surface blowing and adsorbing cleaning mechanism provided by the embodiments of the present application comprises a blowing and adsorbing mechanism 100, a height adjustment structure 200, and a vertical adjustment mechanism 230.

[0083] Therefore, the surface blowing and adsorbing cleaning mechanism of the panel carrier in the application utilizes the cooperation of the blowing and adsorbing mechanism 100 and the height adjusting structure 200 to clean the surface of the panel carrier. The blowing and adsorbing mechanism 100 is provided with a blowing and dust collecting cover 110, and a wind knife 120 for high-pressure blowing of the surface of the panel carrier is arranged in the blowing and dust collecting cover 110, and the blowing port of the wind knife 120 faces the dust collecting port 111 of the blowing and dust collecting cover 110. The dust scattered by the wind knife is not only covered by the blowing and dust collecting cover 110, but also is adsorbed to a designated area by the dust adsorbing port 126 connected to the inner cavity of the blowing and dust collecting cover 110 for collection, so as to prevent the panel carrier from being polluted by dust again after cleaning. The blowing and adsorbing mechanism 100 does not need to be stopped for cleaning, can be repeatedly used for a long time, and prevents dust from scattering everywhere, thereby improving the cleanliness level of the production workshop.

[0084] The surface blowing and adsorbing cleaning mechanism of the panel carrier in the application utilizes the height adjusting structure 200 to adjust the distance between the blowing and adsorbing mechanism 100 and the panel carrier, so as to clean panel carriers of different thicknesses by adjusting the distance between the blowing and adsorbing mechanism 100 and the panel carrier. The height adjusting structure 200 is provided with a height adjusting plate 220 connected to the blowing and adsorbing mechanism 100, and a vertical adjusting mechanism 230 for adjusting the up-and-down movement of the height adjusting plate 220 in the vertical direction is arranged on the mounting plate 210. The vertical adjusting mechanism 230 can be automatically adjusted or manually adjusted. When the vertical adjusting mechanism 230 moves the blowing and adsorbing mechanism 100 towards the panel carrier, the blowing power of the blowing and adsorbing mechanism 100 can be enhanced, and the cleaning efficiency can be improved.
