Coating and curing production line and coating and curing method thereof

Abstract

The invention discloses a coating and curing production line and a coating and curing method thereof, the coating and curing production line comprises at least one operation part, the operation part comprises a coating auxiliary device, the coating auxiliary device comprises a clamping part, the clamping part can be driven to move in the length direction of a to-be-treated product, and the clamping part can clamp the to-be-treated product; the coating device comprises a plurality of liquid pipes used for containing coating liquid; and a curing device; wherein the clamping part straightens the to-be-treated product when moving in the length direction of the to-be-treated product, the coating device coats the to-be-treated product in a sectional mode, the clamping part clamps the to-be-treated product during coating, and the curing device cures the coated product. According to the coating and curing production line, the coating and curing efficiency is high, the coating auxiliary device is arranged, a product can be straightened before coating, the product can be clamped in the early stage of coating for sectional type coating, buoyancy of coating liquid in the liquid pipe is overcome, and a liquid replacing and supplementing device can be arranged to replace or supplement the coating liquid in the liquid pipe.

Description

technical field [0001] The invention relates to the technical field of coating and curing, in particular to a coating and curing production line and a coating and curing method thereof. Background technique [0002] With the development of technology, people have higher and higher requirements for the quality of medical consumables. For example, for interventional medical consumables, most surfaces must have a hydrophilic coating. At present, some medical consumable guide wires, catheters, microcatheters, colonoscopy tubes, gastric tubes, etc. on the market are coated with functional coatings. However, at present, most of the coating production equipment for long guide wire catheters are stand-alone equipment. With the increasing demand for coated products in the market, there are some shortcomings in stand-alone equipment, which are mainly reflected in the following points: 1. Stand-alone The production capacity cannot meet the market demand, and there are few samples of ...

Problems solved by technology

However, at present, most of the coating production equipment for long guide wire catheters are stand-alone equipment. With the increasing demand for coated products in the market, there are some shortcomings in stand-alone equipment, which are mainly reflected in the following points: 1. Stand-alone The production capacity cannot meet the market demand, and there are few samples of jigs and fixtures, and the production capacity is low

2. The product needs to rotate itself during the curing process. For long, thin and soft products, it is easy to shake, and the products are entangled with each other, resulting in product scrapping

3. For ultra-long and thin products, there will be bending phenomenon. During the coating process, due to the influence of the buoyancy of the coating liquid, the product immersion liquid pipe has the risk of bending

4. The existing equipment needs to add the coating solution manually, which increases the trouble of manual work

5. The length of the liquid pipe is the longest length, and the stored coating liquid is the maximum amount. For short-coated products, the utilization rate of the coating liquid is not high

The front and rear ends of the liquid pipe are fixed, and the outer pipe and the inner pipe need to be removed together for disassembly and cleaning, which is a little difficult

6. The position of the product and the light source on the stand-alone device is fixed accordingly, and the curing light source will gradually decay with the prolongation of use time

7. The single-machine curing box is irradiated by a single-side light source. The curing needs to realize the product's rotation. The shaking space required for the rotation is increased, and the number of fixtures hanging is small, resulting in a small production capacity of a single batch.
