Then the second motor drives the slightly higher brush roller 303 to rotate, so that the front and rear overlapping buttons are swept flat, while preventing the friction from causing excessive displacement and repeated stacking of the buttons. Then the buttons reach the sweeping soft brush 307 through the lifting fixed seat 301, and at this time the third motor 304 is started to drive the half-circle gear 306 to rotate. The half-circle gear 306 alternately meshes with the teeth on the upper and lower inner walls of the annular slide 305, so that the annular slide 305 swings back and forth left and right, while driving the left and right to move the buttons that are still stacked left and right. The sweeping soft brush 307 is slightly lower than the brush roller 303, so that only one button can pass through. Finally, the flat buttons pass through the limit plate 308 neatly to the painting position, avoiding the phenomenon of incomplete spraying caused by button stacking.

[0024] In this embodiment: the lifting mechanism includes a support frame 201 arranged on the upper side of the upper conveyor belt 101, a slide rail is opened on the inner side of the support frame 201, a first motor 202 is installed above the support frame 201, the output end of the first motor 202 is connected to a screw 203, and the lifting fixed seat 301 is slidably connected to the slide rail through the screw 203. After the button reaches the position of the support frame 201, the first motor 202 is turned on to drive the screw 203 to rotate so that the lifting fixed seat 301 is lifted, allowing the button to pass.

[0025] In the present embodiment: the first paint spraying mechanism includes a first paint spraying seat 401 arranged at the rear side of the support frame 201, and a first paint spraying port is arranged below the first paint spraying seat 401; the second paint spraying mechanism includes a second paint spraying seat 601 arranged above the lower conveyor belt 102, and a second paint spraying port is installed below the second paint spraying seat 601. First, the flat upper layer and the surrounding area of ​​the button are sprayed through the first paint spraying port, which is convenient and quick. Then, after passing through the flipping mechanism, the other side of the button is sprayed through the second paint spraying port, and the surrounding area is sprayed again to prevent incomplete spraying, and then it is sent out through the lower conveyor belt 102. The first paint spraying seat 401 and the second paint spraying seat 601 are connected with paint tubes, and the other end of the paint tubes is connected with a paint source. This is the prior art known to personnel in this technical field and will not be repeated here.

[0026] In this embodiment: the flipping mechanism includes a baffle 502 arranged at the end of the upper conveyor belt 101, and a C-shaped hollow track 501 is arranged on the rear side of the baffle 502. The lower end of the C-shaped hollow track 501 is welded to the lower conveyor belt 102, and the C-shaped hollow track 501 is respectively connected to the upper conveyor belt 101 and the lower conveyor belt 102 in an arc-shaped and smooth manner. The C-shaped hollow track 501 is a hollow C-shaped slide groove for buttons to pass through, and the upper and lower gaps thereof are twice the thickness of standard buttons. After the buttons sprayed on one side reach the baffle 502, they slide from the C-shaped hollow track 501 to the lower conveyor belt 102 to complete the flipping, which is convenient and quick, and then the next step of painting is carried out.

[0027] The working principle and use process of the utility model are as follows: after the button reaches the position of the support frame 201, the first motor 202 is turned on to drive the lead screw 203 to rotate so that the lifting and fixing seat 301 is lifted up to allow the button to pass through. After the button reaches the leveling mechanism, the lifting and fixing seat 301 is adjusted so that the distance between the limit plate 308 and the upper conveyor belt 101 is slightly higher than the thickness of a button. Then the second motor drives the brush roller 303 to rotate so that the front and rear overlapping buttons are leveled, while preventing the friction from causing excessive displacement and repeated stacking of the buttons. Then the button passes through the lifting and fixing seat 301 to reach the leveling soft brush 307. At this time, the third motor 304 is started to drive the half-circle gear 306 to rotate. The half-circle gear 306 alternately meshes with the teeth on the upper and lower inner walls of the annular slide 305, so that The annular slide 305 swings back and forth, and at the same time drives the buttons that are still stacked on the left and right to be toggled left and right. The smoothing soft brush 307 is slightly lower than the brush roller 303, so that only one button can pass through. Finally, the flat buttons pass through the limit plate 308 to neatly reach the painting position, avoiding the phenomenon of incomplete spraying caused by button stacking. The buttons are first sprayed on the upper layer and around the flat buttons through the first painting port, which is convenient and fast. After the buttons with spraying on one side reach the baffle 502, they slide to the lower conveyor belt 102 by the C-shaped hollow track 501 to complete the turning over, which is convenient and fast. Finally, the other side of the button is sprayed through the second painting port, and the surroundings are sprayed again to prevent incomplete spraying. The buttons with spraying are then sent out through the lower conveyor belt 102.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
