Step 2: the translation motor 71 drives the translation screw rod 74 to rotate under the connection of the coupler 72, after the support member 73 connected with the translation screw rod 74 and the translation slide rail 75 and the carrier 6 installed on the support member 73 move to the position right above the liquid storage tube 407 provided with the corresponding coating liquid on the lifting coating device 4 along the translation slide rail 75 under the drive of the translation screw rod 74, the coating bin 40 of the lifting coating device 4 continues to move upwards along with the lifting screw rod 405, so that the part to be coated of the catheter 9 completely enters the liquid storage tube 407 to be coated.

And step 3: after coating, the lifting motor 401 drives the coating chamber 40 to descend to the initial position, the air cylinders 418 on both sides of the through hole on the mounting plate 101 extend to cover the light-shielding door 412, and the detection devices 420 on both sides detect whether the light-shielding door 412 is completely closed to the position, and in this embodiment, a hall switch is preferably used as the detection device 420.

And 4, step 4: after the coating bin 40 is lowered to the initial position, the translation motor 71 continues to drive the translation screw rod 74 to rotate, and drives the carrier 6 to move to the curing position.

And 5: the lifting cylinder 32 contracts to drive the second light shielding plate 310 to move downwards, the light emitted by the curing lamp 52 of the light unit 5 irradiates on the coated catheter 9, at this time, the speed reducing motor 602 drives the driving gear 603 connected with the driving shaft 604 and the driving shaft 604 to rotate, the driving gear 603 drives the driven gear 606 engaged with the driving gear to rotate around the driven shaft 605, and the driven gear 606 drives other self-rotating gears 608 engaged with each other to rotate, so that the loading shaft 607 and the catheter 9 arranged on the loading shaft 607 are driven to rotate to complete curing;

step 6: after the curing is finished, the lifting cylinder 32 extends out to push the second light shielding plate 310 out of the curing lamp 52 covered with the illumination unit 5, then the steps 1 to 5 are repeated to finish the coating curing of the 2 nd layer, the 3 rd layer and the nth coating liquid of the catheter 9, and after the coating curing is finished completely, an operator opens the switch door and takes out a finished product.

In addition, when the product is coated and cured for the first time, the carrier 6 can also be directly mounted on the support plate 76, the carrier 6 is not translated, and the position of the carrier 6 is directly used as a curing position, so that when the shading door in step 1 is opened during the first curing, the coating bin 40 of the lifting coating device 4 in step 2 continues to move upwards along with the lifting screw rod 405, so that the part to be coated of the catheter 9 completely enters the liquid storage tube 407 for coating, step 3 is performed again, step 5 is performed again, and after the final curing is completed, an operator opens the opening and closing door and takes out the finished product.

(1) according to the coating and curing equipment, the illumination unit is fixed, and the coating device moves up and down to coat and cure the product, so that the equipment is simple in structure, high in space utilization rate and compact in structure;

(2) according to the coating and curing equipment, the carrier shaft for mounting the catheter can be changed according to different specifications and models of the catheter, and can be compatible with various products of different specifications and models, so that the production efficiency and the use efficiency of the equipment are improved;

(3) according to the coating and curing equipment, the carrier can enable the catheter to rotate in the curing process, so that each surface of the catheter can receive illumination more uniformly, and all parts of the catheter can be effectively irradiated even under the condition of sparse light source;

(4) according to the coating and curing equipment, the two groups of liquid storage tubes are arranged on the coating device, so that the catheter can be coated with two layers of different coating liquids, and the two layers of different coating liquids are cured after being coated for two times to share one light source, so that the utilization rate of the light source is improved, the light source is saved, and the cost is reduced;

(5) according to the coating curing equipment, the carrier shafts on the carriers are arranged in a staggered manner, so that a plurality of carriers can be arranged, the production requirements are met, and the production efficiency is improved.
