step four: starting the hydraulic cylinder 31 to drive the rotating platform 32 to descend and simultaneously drive the clamp 34 to rotate; a spray head 36 communicated with the stirring bin 2 and used for spraying the paint formed after stirring is started, and the spray head 36 sprays the rotating shell body 11;

step five: the hydraulic cylinder 31 drives the rotating platform 32 to move upwards and attach to the surface of the shell body 11, and the first motor 35 is started to drive the rotating platform 32 to rotate ninety degrees, so that the other two opposite corners of the shell body 11 are clamped by the clamp 34;

step six: the hydraulic cylinder 31 is started again to drive the rotating platform 32 to descend and simultaneously drive the clamp 34 to rotate; simultaneously, the spray head 36 communicated with the stirring bin 2 is started, and the spray head 36 sprays the rotating shell body 11 again;

step seven: the sealing door 37 is opened, and the case body 11 with the surface coated with the high temperature resistant and ultraviolet resistant paint protective layer 12 is taken out.

The working principle and the using process of the method are as follows:

adding the components into a stirring bin 2 according to the mass ratio, stirring for 50min by a high-speed stirrer 21 at the rotating speed of 220r/min, and fully mixing the raw materials in the coating protective layer 12; the spraying bin 3 is opened by manually rotating the handle and pulling the sealing door 37 outwards, then the two opposite corners of the housing body 11 of the notebook computer are inserted into the two clamps 34 which are opposite from left to right and are clamped and fixed by the clamps, then the sealing door 37 is closed again, at this time, the hydraulic cylinder 31 is started to descend, the spray head 36 is started to spray, the output shaft of the hydraulic cylinder 31 contracts downwards, so as to drive the rotating platform 32 at the top end of the output shaft to descend, wherein when the thread 311 of the output shaft is screwed with the transmission nut 331, the transmission nut 331 rotates, the belt pulley 333 is driven to rotate by the belt 332, the belt pulley 333 drives the first bevel gear 335 at the upper end to rotate by the shaft lever 334, the first bevel gear 335 is meshed with the second bevel gear 336 to rotate, the second bevel gear 336 drives the clamp 34 fixedly connected with the second bevel gear 336 to rotate longitudinally by the connecting part 341 of the clamp 34, another clamp 34 is fixed in the side groove of the spraying bin 3 at the other side through a bearing to match the rotation of the shell body 11, so as to realize the turnover of the whole shell body 11, at this time, the coating sprayed from the right above can be uniformly sprayed on the outer wall of the shell body 11, then the hydraulic cylinder 31 is pushed upwards in the reverse direction to drive the rotating platform 32 to ascend and the clamp 34 to reversely rotate, so as to reset the shell body 11 again in the reverse direction, when the rotating platform 32 moves to the upper side, the upper end of the rotating platform 32 is attached to the lower surface of the shell body 11, the peripheral limit blocks 321 of the rotating platform 32 limit the four sides of the shell body 11 in a clamping manner, then the first motor 35 is started, the first motor 35 drives the rotating platform 32 to rotate, so that the rotating platform 32 horizontally rotates and removes the shell body 11 from the clamp 34 through the four limit blocks 321, and then rotates and inserts the other two corners of the shell body 11 into the clamp 34 after rotating ninety degrees, the coating is clamped and fixed, then the process is repeated, the hydraulic cylinder 31 is lowered, the clamp 34 drives the shell body 11 to overturn, two corner parts of the coating which is not sprayed due to clamping are uniformly sprayed, and comprehensive spraying treatment is achieved.

Two symmetrical clamps 34 for clamping opposite corners of the shell body 11 are arranged inside the spraying bin 3, one of the clamps 34 is in transmission connection with the hydraulic cylinder 31 through a transmission piece 33, and the upper end of the hydraulic cylinder 31 is provided with a rotating table 32 for driving the shell body 11 to rotate and change directions.

It should be noted that: the clamp 34 clamps any one of two opposite groups of corners on the housing body 11 to drive the other group of corners to overturn, so that coating on the other group of corners is sprayed, and the two groups of corners are alternated to realize all-dimensional spraying on the housing body 11.

Among them carry out the centre gripping to the corner, on the one hand make the position area of anchor clamps 34 centre gripping less, guarantee that whole shell most area all can be sprayed, on the other hand is because the centre gripping area is little, made things convenient for dismantlement and installation on anchor clamps 34, simultaneously because notebook computer housing body 11 is the rectangle, thereby the distance between two corners of diagonal angle is the farthest, it is the biggest also to rotate the circle that forms when revolving stage 32 drives its rotation, four stopper 321 that this moment lie in housing body 11 four sides department can not form at the pivoted in-process yet and block, avoided disturbing to carrying out the switching at housing body 11 corner in anchor clamps 34.

The bottom of the spraying bin 3 is set to be a slope bottom, the outer wall of the spraying bin is provided with a circle of recovery ditch, and the recovery ditch is used for carrying out outward discharge and collection by arranging an outer discharge hole.

Specifically, the method comprises the following steps of; the bottom in spraying storehouse 3 sets up to the slope end to the convenience will scatter and glide in the raw materials of bottom, all fall into bottom recovery ditch all around, and glide to the outer round of lowest along retrieving the ditch in, retrieve, avoided the waste of raw materials.

The lower surface of the bottom of the spraying bin 3 is provided with a hydraulic cylinder 31, an output shaft of the hydraulic cylinder 31 is provided with a section of thread 311, and the thread 311 is in threaded connection with a transmission nut 331 fixed on the top surface of the bottom of the spraying bin 3 through a bearing.
