After the pointer 8 points to the position of the corresponding scale line 6, the limit screw 12 is turned to fix the slide 10 in the base 1. The first cylinder 16 pushes the brush handle close to the brush head through the mounting shell 19. At this time, the lever 15 contacts the contact switch 9 to stop the first cylinder 16 at the corresponding position. In this way, effective position positioning can be performed according to the sizes of different endoscope clamp hole cleaning brushes, thereby ensuring the yield rate of its processing;

[0030] The feeding assembly 2 includes a sliding mounting seat 14, and a lever 15 is provided on one side of the sliding mounting seat 14 close to the positioning assembly 5. The lever 15 is opposite to the contact switch 9. The contact switch 9 is electrically connected to a solenoid valve and the solenoid valve is used to control the start and stop of the first cylinder 16. The contact switch 9 is connected to a processor for controlling the start and stop of the solenoid valve.

[0031] The positioning assembly 5 also includes a limit screw 12, which is threadedly connected to the slide 10. A hand wheel 13 is provided at the top of the limit screw 12. The hand wheel 13 turns the limit screw 12, so that the limit screw 12 can squeeze the slide 10 to fix it in the base 1.

[0032] The feeding assembly 2 also includes a guide rail 17, a mounting plate 18, a mounting shell 19, and a movable clamp 20. The guide rail 17 is installed on the base 1, and the sliding mounting seat 14 is slidably connected to the upper part of the guide rail 17.

The brush handle and the brush head are plugged in. The driving motor 2 The limiting slider 27 is driven by the double-headed screw 28 to drive the heating substrates 25 to approach each other. At this time, a heated circular channel is formed between the heating substrates 25, and the brush head and the brush handle are melt-welded. Welding materials can also be set therein to weld the brush head and the brush handle. During welding, the positioning hoops 26 on both sides of the heating substrate 25 can limit the movement of the brush head and the brush handle. In this way, the slender endoscope channel hole cleaning brush can be positioned and welded by mechanical means during welding, avoiding the situation of many defective products caused by manual welding.

[0037] When the endoscope channel hole cleaning brush production device is actually used, the brush handle of the cleaning brush is placed in the chamber 21, and the air valve 22 drives the movable clamp 20 to slide in the mounting shell 19 through compressed air to clamp the cleaning brush handle. Because the cleaning brush handle is relatively delicate, a silicone pad is provided in the movable clamp 20 to protect the brush handle. Then the second cylinder 32 pushes the adjustment plate 34 to move the arc clamp 35 to the position of the same symmetry axis of the movable clamp 20, and the brush head is placed in the arc clamp 35. The third cylinder 33 drives the upper arc clamp 35 to clamp the brush head. At this time, according to the welding depth of the brush handle and the brush head, the limit screw 12 is turned through the hand wheel 13, and then the slide 10 is moved to the corresponding position. After the pointer 8 points to the corresponding scale line 6 position, the limit screw 12 is turned to fix the slide 10 in the base 1. , the first cylinder 16 pushes the brush handle close to the brush head through the mounting shell 19, at this time the lever 15 contacts the contact switch 9 to stop the first cylinder 16 at the corresponding position, at this time the brush handle and the brush head are plugged in, the driving motor 29 drives the limiting slider 27 to drive the heating substrate 25 to approach each other through the double-headed screw 28, at this time, a heated circular channel is formed between the heating substrates 25, the brush head and the brush handle are melt-welded, and welding materials can also be set therein to weld the brush head and the brush handle, when welding, the positioning hoops 26 on both sides of the heating substrate 25 can limit the movement of the brush head and the brush handle, so that the slender endoscope forceps channel hole cleaning brush can be mechanically positioned and welded when welding, avoiding the situation of many defective products in manual welding, and at the same time, the integrated hot-melt welding of the endoscope forceps channel hole cleaning brush can also have good strength.
