[0025] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] See also Figure 1 , Figure 2, the present invention provides the following technical solutions: an aluminum plate coating drying device, comprising a drying box 1, and a loading bracket 2 arranged in the drying box 1, the drying box 1 is a cylindrical structure, a drying mechanism is arranged in the drying box 1, and the loading bracket 2 is used for horizontally loading the aluminum plate;

[0027] The plate surface detection mechanism 3, the side of the drying box 1 is transparent, and the plate surface detection mechanism 3 includes a base 301 sleeved on the drying box 1, and two groups of photoelectric sensors 310 arranged in the base 301 and located in the same horizontal plane. In this embodiment, the photoelectric sensor 310 is a through-beam photoelectric sensor, and the light emitter and the light receiver of the same group of photoelectric sensors 310 are respectively installed on both sides of the loading bracket 2. When there is a protrusion on the surface of the aluminum plate, the protrusion position will block the light path, and the light receiver will generate a signal and transmit the signal to the controller;

[0028] like Figure 3 As shown, the detection lines of the multiple photoelectric sensors 310 in the same group are parallel, and the detection lines of the two groups of photoelectric sensors 310 are perpendicular to form a detection grid structure;

[0029] The detection grid structure can form a determined coordinate area, and according to the blocked parts of the two groups of photoelectric sensors 310, the convex position can be roughly determined, thereby determining the place where the coating cloth on the surface of the aluminum plate is flat;

[0030] A moving mechanism 4, wherein the moving mechanism 4 is arranged on the top of the drying box 1;

[0031] An air jet mechanism 5, which is arranged on the moving mechanism 4 and can be driven by the moving mechanism 4 to any position in the detection grid, and the air jet mechanism 5 can blow the raised position on the surface of the aluminum plate through air flow;

[0032] According to the uneven position of the aluminum plate surface determined by the plate surface detection mechanism 3, the controller drives the jet mechanism 5 to move to the coordinate of the uneven position through the moving mechanism 4, and then generates airflow to the uneven position, and generates blowing pressure through the airflow to flatten the convex position. Compared with the pressure roller, the coating will not stick to the pressure roller, making the coating thinner;

[0033] In order to have an adjustable painting method, in a further embodiment, as Figure 2 As shown, the jet mechanism 5 includes a multi-directional mechanical arm 501 connected to the moving mechanism 4, a jet pipe 502 vertically arranged and connected to the multi-directional mechanical arm 501, and a jet head 503 connected to the jet pipe 502. The multi-directional mechanical arm 501 can generate vertical telescopic, vertical in-plane rotation, and horizontal in-plane rotation movements;

[0034] In order to reduce the influence of airflow on the normal coating near the protrusion, in a further embodiment, as Figure 4As shown, the jet mechanism 5 also includes a return air pipe 504 sleeved on the jet pipe 502, the jet head 503 is located inside the return air pipe 504, the return air pipe 504 and the jet pipe 504 are opened and closed at the same time, and the return air pipe 504 and the jet pipe 502 are coaxially arranged;

[0035] After the gas ejected from the air jet head 503 acts on the protrusion, the airflow is dispersed in the circumferential direction of the protrusion. By adjusting the strength of the blowing effect of the return air pipe 504 relative to the air jet pipe 502, the dispersed airflow is sucked by the return air pipe 502 and no longer moves to the side of the protrusion but is discharged from the return air pipe 504, thereby reducing the influence of the airflow on the normal coating position.

[0036] In order to ensure that the airflow can fully act on the raised position and then be sucked away by the return air pipe 504, in a further embodiment, Figure 5 As shown, the end of the air jet pipe 502 is coaxially sleeved with an annular eaves body 505, the eaves body 505 is arranged inside the air return pipe 504, the eaves body 505 extends outward from top to bottom, and the air jet head 503 is fixed inside the eaves body 505;

[0037] Due to the shielding effect of the eaves 505, the airflow generated by the jet pipe 502 moves to exceed the eaves 505 before being sucked out by the return air pipe 504;

[0038] In order to further improve the exhaust effect, in a further embodiment, a first guide portion 506 with a diameter gradually decreasing from top to bottom is provided at the bottom of the return air pipe 504, and a second guide portion 507 having the same shape as the first guide portion 506 is connected between the bottom end of the eaves 505 and the air injection pipe 502, so that a guide return air channel 508 is formed between the first guide portion 506 and the second guide portion 507;

[0039] When the airflow of the air jet pipe 502 acts on the protrusion, as the protrusion gradually flattens, the airflow changes from top to bottom and from inside to outside to inside to outside. Under the effect of the return air channel 508, the suction airflow formed at the bottom of the return air pipe 504 is from inside to outside and from bottom to top, which can produce a good suction effect for the entire air jet process and reduce the airflow escaping outward.

[0040] In order to adapt to the detection of aluminum plates of different thicknesses, in a further embodiment, as Figure 2 As shown, the base 301 is slidably matched with the drying box 1, and a plurality of first telescopic members 101 are provided on the side of the drying box 1, and the telescopic rods of the first telescopic members 101 are vertically telescopic and connected to the base 301;

[0041] The first telescopic member 101 can drive the base 301 to move vertically to adjust the height of the photoelectric sensor 310 so as to adapt to aluminum plates of different thicknesses;

[0042] In this embodiment, the first telescopic member 101 is a servo telescopic cylinder and is connected to the controller. The distance information after vertical movement will also be received by the controller. During the detection process, the photoelectric sensor 310 is moved vertically to enable the detection grid structure to be detected at different heights, thereby determining the height of the protruding position, so as to adjust the height of the jet mechanism 5 according to the protruding height.

[0043] In order to adapt to the detection of aluminum plates with inclined surfaces, in a further embodiment, as Figure 2 As shown, the base 301 includes two base plates 302 arranged in parallel and slidably matched with the drying box 1, and a support plate 303 connecting the two base plates 302. Coaxial and horizontal rotating shafts 304 are fixedly provided on the support plates 303 on both sides. An annular rotating seat 305 is rotatably connected between the two rotating shafts 304. The photoelectric sensor 310 is provided on the inner side of the rotating seat 305. An adjusting member 320 is provided on the base plate 302 and is transmission-connected to the rotating seat 305.

[0044] The adjusting member 320 can drive the rotating seat 305 to tilt within a certain angle range, so that the entire detection grid is tilted;

[0045] In order to make the detection grid appear to cover the entire surface of the aluminum plate, in a further embodiment, the base plate 302 includes a sliding portion 306 that is slidably matched with the drying box 1, and a rotating portion 307 that is rotatably connected to the sliding portion 306, the first telescopic member 101 is connected to the sliding portion 306, the support plate 303 is fixedly connected to the two rotating portions 307, the rotating portion 307 is transmission-connected to a driving member that can drive it to rotate, and is provided with a sensor for detecting its rotation angle, and the rotation angle sensor is connected to the controller;

[0046] After the rotating part 307 rotates, its rotation angle information is transmitted to the controller, and the controller can determine the position of the detection grid at this time, and according to the convex position information detected at the current detection grid position, combined with the initial detection information, it can be obtained which positions on the surface of the aluminum plate have convexities. After multiple rotation detections, more accurate detection information can be obtained;

[0047] Specifically, Figure 1 As shown, the adjusting member 320 includes a second telescopic member 321 fixed on the rotating portion 307 , a connecting rod 322 rotatably connected to the telescopic rod of the second telescopic member 321 , and the connecting rod 322 is rotatably connected to the rotating seat 305 .

[0048] In order to form a corresponding moving route area corresponding to the detection grid, in a further embodiment, the moving mechanism 4 includes a first linear moving component 401 fixed to the top of the drying box 1, and a second linear moving component 402 connected to the first linear moving component 401 and moving therewith, the moving route of the second linear moving component 402 is perpendicular to the first linear moving component 401, and the second linear moving component 402 is connected to the jet mechanism 5;

[0049] The moving routes of the first linear moving component 401 and the second linear moving component 402 are respectively parallel to the detection routes of the two groups of photoelectric sensors 310 in the initial state, which can help to quickly adjust the position of the jet mechanism 5 according to the detected position information.
