Description

Technical Field

[0001] The utility model relates to the technical field of laser marking, and more specifically, it relates to a laser marking device for composite catheters. Background Art

[0002] Composite catheters are often used in the medical field for certain minimally invasive surgeries. After the composite catheters are produced, it is necessary to use a laser marking device to mark on the outer side of the tube to indicate the manufacturer and production batch number, etc. When a large number of defective products appear, the corresponding manufacturer and production batch can be quickly traced according to the marking information on the tube body, which is convenient for unified recall or rework of the products in this batch. In the current laser marking device, when processing composite catheters, generally the two ends of the catheter are fixed manually, stretched and straightened outward and then placed at the laser marking device for processing. This method has certain safety hazards; in addition, composite catheters are generally made of silica gel material. During the laser marking process, some harmful gases and irritating odors will be generated, which will pose a certain threat to the health of workers when diffused in the air.

The limiting plate 26 is fixedly arranged on one side of the mounting frame 22. Rubber pads 30 are provided in the clamping grooves 10 on the first elastic sheet 3 and the second elastic sheet 4.

[0029] In this embodiment, both ends of the composite catheter are respectively snapped into the clamping grooves 10 from the V-shaped grooves 11 on the first elastic sheet 3 and the second elastic sheet 4. The two ends of the composite catheter are clamped by the clamping grooves 10. At this time, the middle section of the composite catheter is in a free and anti-loosening state. Rotate the knob 12 to drive the lead screw 8 to rotate, and then drive the first moving seat 5 and the second moving seat 6 to move to both sides along the direction of the first guide rod 9, driving the composite catheter to gradually become a straight state.

At this time, the composite catheter is marked by the laser marking head 2. During this process, start the external air pump to extract the gas generated by marking through the dust removal cover 20 and the mounting pipe 19.

[0032] In summary, when the overall device is in use or operation: insert both ends of the composite conduit into the clamping grooves 10 respectively from the V-shaped grooves 11 on the first elastic piece 3 and the second elastic piece 4. Clamp both ends of the composite conduit through the clamping grooves 10. At this time, the middle section of the composite conduit is in a free and anti-loosening state.

At this time, the composite conduit can be marked by the marking device. After marking, rotate the receiving plate 23 outwards to drive the magnifying glass 24 out of the protective box 25 until the receiving plate 23 fits with the limiting plate 26. At this time, the marked area can be observed through the magnifying glass 24 to judge whether it is qualified. If it is qualified, take out the composite conduit and replace it with a new one for marking.

[0033] When marking the composite conduit, at this time, the connecting hose 21 is externally connected to an air pump, and the lifting cylinder 14 is started to drive the lifting plate 15 and the mounting plate 17 to move downward to a suitable position. At this time, the composite conduit is marked by the laser marking head 2. During this process, start the external air pump to extract the gas generated by marking through the dust removal cover 20 and the mounting pipe 19.
