The third embodiment is different from the second embodiment in that: further, the bearing assembly 323 comprises a support frame 3231, and a first support unit 3232 and a second support unit 3233 which are symmetrically arranged on the support frame 3231 in a front-back manner, each of the first support unit 3232 and the second support unit 3233 comprises a guide pillar 3234, a guide sleeve 3235 and a bearing block 3236, the guide pillar 3234 is fixedly arranged at the end of the support frame 3231 in a left-right manner, the guide sleeve 3235 is sleeved on the guide pillar 3234, the two ends of the bearing block 3236 are fixedly arranged on the guide sleeve 3235 at the left side and the right side, and a spring c3237 is arranged between the guide sleeve 3235 and the support frame 32; the support surface of the bearing block 3236 is provided as a ramp.
It is worth mentioning that, in this embodiment, through front and back symmetry setting first supporting unit 3232 and second supporting unit 3233 on support frame 3231, and set up bearing block 3236 holding surface of first supporting unit 3232 and second supporting unit 3233 to be the inclined plane, make it when supporting the panel 10 of accomplishing the coating, it is the side corner of panel to support, the coating of direct contact panel 10 lower surface has been avoided to this kind of supported mode, cause the damage to the coating, in addition through setting up bearing block 3236 to be an elastic lifting makes panel 10 be flexible contact when the whereabouts, avoid causing the damage to panel 10 side corner.
The working process is as follows:
the horizontal pushing cylinder a132 pushes the plate 10 to move towards the coating opening 111 and simultaneously pushes the cover plate 14 to move away from the coating opening 111, meanwhile, the connecting frame 134 driven by the horizontal pushing cylinder a132 drives the adsorption disc 221 to move downwards through the traction rope 224, when the cover plate 14 is completely moved away from the coating opening 111, the plate 10 just completely moves above the coating opening 111, and at the moment, the lower surfaces of the adsorption nozzle a225 and the adsorption nozzle b233 on the adsorption disc 221 just adhere to the upper surface of the plate 10;
at the initial stage of the horizontal pushing cylinder a132 pushing the plate 10 and the cover plate 14 to move, the push-pull rod 135 on the connecting frame 134 slides along the chute 123 at the end of the push rod 122, after moving a certain distance, the push-pull rod 135 starts to drive the push rod 122 and the press plate 121 to move together with the plate 10, the press plate 121 compresses the paint in the extrusion chamber 30, the paint level in the paint chamber 20 rises, the paint starts to contact the lower surface of the plate 10, because the plate 10 and the cover plate 14 move close to each other to form a relative seal, no excessive paint can be flushed from the coating port 111, when the paint in the bin 11 is excessive, the excessive paint extruded with the press plate 121 can extrude the overflow block 182 and enter the overflow box body 181 for temporary storage;
when the plate 10 completely moves to the upper part of the coating opening 111, the lower surface of the plate 10 is coated with the coating, the adsorption nozzle a225 and the adsorption nozzle b233 also adsorb the upper surface of the plate 10, then the horizontal pushing cylinder a132 is reset reversely, in the resetting process, the adsorption disc 221 is driven by the traction rope 224 to move upwards together with the plate 10 adsorbed and fixed by the adsorption nozzle a225 and the adsorption nozzle b233, the pressing plate 121 is also reset under the driving of the pressing plate 121, when the resetting is completed, the plate 10 rises to a certain height, the horizontal pushing cylinder b321 and the horizontal pushing cylinder c322 drive the pushing block 3211 to push the cover plate 14 to reset, and the material homogenizing roller 311 above the front side of the cover plate 14 performs roller homogenizing on the coating on the lower surface of the plate 10 in the moving process;
when the cover plate 14 is completely restored to cover the coating opening 111, the lever 324 pushes the sliding rod 903 to slide along the guiding hole b2213 to enable the first cover plate 901 and the second cover plate 902 to cover the first communicating hole 70 and the second communicating hole 80 respectively, in the process, the spring a905 is compressed, the adsorption force of the adsorption nozzle a225 is greatly reduced, the plate 10 is separated from the adsorption nozzle a225 and only can be adsorbed and supported by the adsorption nozzle b233 of the lowering mechanism 23, the lifting pipe 232 starts to slide downwards along the communicating pipe 231 and stretches the spring b234, the plate 10 slowly descends along the spring b, in the descending process, the air outlet 313 on the cover plate 14 blows air to dry the coating of the plate 10, in the blowing process, the plate 10 swings in a small amplitude, when the plate descends to the limit position, the air vent a2311 on the side edge of the lower end part of the communicating pipe is communicated with the air vent b2321 on the same side edge of the upper end part of the lifting pipe 232, the interior of the communicating, the adsorption force of the adsorption nozzle b233 is greatly reduced in the same way, and then the plate 10 and the adsorption nozzle b233 are separated and completely lowered to the bearing component 323, the side corner of the bottom of the plate 10 leans on the inclined plane of the bearing block 3236, then the horizontal pushing cylinder b321 and the horizontal pushing cylinder c322 drive the bearing component 323 to reset and output together with the plate 10, after resetting, the first cover plate 901 and the second cover plate 902 reset under the action of elastic force, and the lifting pipe 232 resets under the action of elastic force to wait for the next plate 10 to transfer.
