Description

Technical Field

[0001] The invention relates to the technical field of hypotube spraying processing, and in particular to a high-precision feeding device and method for hypotube spraying processing. Background Art

[0002] Hypotube is a long metal capillary, an important component of minimally invasive treatment catheter, and a container for storing and transporting hydrogen peroxide. Hypotube is usually made of corrosion-resistant materials such as stainless steel, polytetrafluoroethylene (PTFE), polyethylene (PE), etc. Hypotube spraying is a special surface treatment process used to coat a protective film or functional coating on the surface of the hypotube. This process can improve the corrosion resistance, wear resistance, conductivity or other specific properties of the hypotube. Hypotube spraying generally needs to be carried out in a clean and dust-free spray room. Multiple spraying stations are designed in the spray room to carry spray molds or spray gun nozzles to ensure the spraying quality of the hypotube. However, in the existing technology, the hypotube is generally fed manually, and one end of the hypotube is sent to the spraying station in the spray room. However, the accuracy of manual feeding cannot be guaranteed, which has a certain impact on the spraying quality of the hypotube.

[0003] The existing Chinese patent document with publication number CN109201378B proposes a bidirectional feed type roller surface spraying device, which solves the above technical problems by arranging clamping mechanisms and feeding mechanisms on both sides of the sprayer to cooperate, and driving the two clamping mechanisms to move to realize automatic feeding along the axial direction of the roller when the sprayer is in operation. However, the hypotube is a long metal capillary, and during the spraying process, it must be ensured that the spraying is carried out in a dust-free and clean spraying room. Therefore, only the movable hypotube can be fed and the loading and unloading can be coordinated. The spray feeding device of the prior art is still used for hypotube spraying processing. There is still a problem of low precision.

3. A high-precision feeding method for hypotube spraying, implemented by a high-precision feeding device for hypotube spraying according to any one of claims 1-2, characterized in that: The following steps are involved: Step 1: Loading the hypotube. The loading rack lifts and pushes out a single hypotube with the cooperation of the loading pushing telescopic rod. The pneumatic clamping fixture clamps the hypotube in the middle of the anti-slip and wear-resistant silicone plate. The loading drive assembly drives the feeding movable platform to move, so that the pneumatic clamping fixture clamps the hypotube for feeding; Step 2: Straightening during feeding. The pneumatic clamp clamps the hypotube for feeding through the calibration sleeve, which is identified by the induction sensor. The movable rack approaches the feeding roller under the drive of the small telescopic rod, which exerts a certain pressure on the surface of the hypotube. The feeding roller is driven by the driving assembly at the bottom of the feeding platform to rotate, and the hypotube is straightened in the process of feeding the hypotube; Step 3: Positioning and guiding. The hypotube is guided through the guide block so that the hypotube is accurately fed into the positioning sleeve on one side of the spray positioning rack and accurately enters the spray die nozzle to wait for spraying; Step 4: Spraying. When the hypotube is fed After completion, the locking telescopic rod returns to the pulling and pushing plate to drive the locking sleeve to squeeze the front end of the rotating rod. The front end of the clamping pad is compressed to gather the clamping pad, and the anti-slip pad will clamp the hypotube. At this time, the driving assembly behind the rotating rod will drive the rotating rod to rotate, so that the hypotube rotates for spraying processing; step five, withdraw the material. After the hypotube is sprayed, the rotating rod stops rotating, and the locking telescopic rod pushes the pushing plate to withdraw and cancel the clamping of the clamping pad. The feeding drive assembly drives the feeding rack to retreat, and after exiting the feeding platform area, the lifting telescopic rod lifts the clamping table, so that the pneumatic clamping fixture drives the sprayed hypotube to lift. At this time, the telescopic rod of the stripping plate pushes the stripping plate to cover the top of the feeding and mounting frame, and finally the pneumatic clamping fixture releases the hypotube so that it falls on the stripping plate, completing the material withdrawal. The telescopic rod of the stripping plate pulls the stripping plate to withdraw, and the triangular feeding plate is exposed again, and the next hypotube feeding and spraying is carried out.
