[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be described clearly and completely in combination with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0031] The high-precision capillary automatic cutting method of the preferred embodiment of the present invention is as follows: Figure 1 As shown, the following steps are included:

[0032] S01: After moving the capillary to the cutting station, clamp and fix the capillary;

[0033] S02: driving multiple cutters on the annular tool to close and clamp the cutters on the capillary tube at the position to be cut, and driving the annular tool to rotate to cut an annular groove on the outer surface of the capillary tube;

[0034] S03: Pressing the end of the capillary along the radial direction of the capillary to break the capillary from the annular groove;

[0035] By using the method of the present application, the capillary is pressed radially after annular rotary cutting by an annular tool, with a fast processing speed and high incision flatness. It is also suitable for automated production, does not require manual operation, and has high safety.

[0036] Preferably, in the second step, pressure is applied to the multiple cutters to press them against the capillary surface; the number of cutters is not less than three; this facilitates ensuring a better grooving effect and ensuring the flatness of the capillary cut.

[0037] Preferably, in the third step, the annular tool is moved radially along the capillary to press and break the end of the capillary; this facilitates automated control, and at the same time, the annular tool has the functions of both grooving and pressing and breaking the end of the capillary, resulting in high processing efficiency and low equipment cost.

[0038] Preferably, in the third step, a groove or a sleeve for accommodating the end of the capillary is provided on the annular tool, and the annular tool is moved along the radial direction of the capillary and a pressing and breaking force is applied to the end of the capillary through the inner wall of the groove or the inner wall of the sleeve; the end of the capillary is conveniently positioned through the groove or the sleeve, thereby ensuring the stability of the capillary during rotary cutting by the annular tool, thereby ensuring the rotary cutting accuracy, and at the same time, the distance between the ends of the capillary cut by the movement of the annular tool after rotary cutting is short, and the processing efficiency is high.

[0039] Better, such as Figure 2 As shown, when a groove 10 is provided on the annular cutter 1: a groove 11 for the end of the capillary 2 to enter is provided on one side wall of the groove 10; the groove 11 is in the same direction as the radial movement of the annular cutter 1 along the capillary 2, and in the initial state, the groove 11 is directly opposite to any gap of the plurality of cutters 12;

[0040] In the second step, the annular cutter 1 is transversely moved along the radial direction of the capillary 2 so that the end of the capillary 2 passes through a cutter gap and enters the groove 10 through the slot 11;

[0041] In the third step, the annular cutter 1 is further radially moved in the direction of the second step, and a force for pressing and breaking the end of the capillary 2 is applied through the inner wall of the groove 10;

[0042] In this way, the circular cutting tool 1 moves transversely along the radial direction of the capillary 2 until the capillary 2 is located in the groove 10. At this time, the capillary 2 is located at the cutting center of the circular cutting tool 1. After rotary cutting, the circular cutting tool 1 continues to move in the original direction to cut off the end of the capillary 2 to complete the cutting action.

[0043] At this time, the circular cutting tool 1 only needs the power for closing and opening the cutter 12, the power for rotating cutting and the power for radial movement. It is easy to control, and the capillary 2 has a time-distance positioning function when entering the slot. The overall equipment will be very compact, small in size, small in moving stroke, and the efficiency will be greatly improved.

[0044] Another optional setting method is Figure 3 As shown: a tube sleeve 13 is provided on the annular cutter 1;

[0045] In the second step, the annular cutter 1 is moved toward the end of the capillary 2 so that the end of the capillary 2 enters the sleeve 13;

[0046] In the third step, the annular cutter is moved along the radial direction of the capillary 2 to apply a force to press and break the end of the capillary 2 through the inner wall of the sleeve 13 .

[0047] In this case, the annular cutter needs to be moved first to make the end of the capillary enter the sleeve for positioning, and then the rotary cutting is performed, and finally the capillary is cut by moving along the radial direction of the capillary. Compared with the previous method, there is an additional driving force to move toward the capillary, and the function of rotary cutting, cutting and positioning is also achieved.

[0048] Another implementation method is: in the third step, the end of the capillary is pressed and broken by moving the annular cutter along the radial direction of the capillary with the help of a cutter or a cutter mounting seat; this method can also achieve the processing purpose and also belongs to the scope of protection of this application;

[0049] The multi-axis drive of the annular cutter can be realized by using a conventional multi-axis drive assembly, and the opening and closing of the cutter on the annular cutter can be realized by using an existing structure;

[0050] A high-precision capillary automatic cutting device is used to implement the high-precision capillary automatic cutting method as described above, such as Figure 4 See also Figure 5 , including a clamping assembly 3 for clamping and fixing a capillary tube 2, a circular cutting tool 1 and a driving mechanism 5;

[0051] The circular cutting tool 1 includes a tool mounting seat and a plurality of cutting knives 12 arranged in a circular ring distribution. A transmission gear 120 is fixed at one end of the cutting knife 12, and the transmission gear 120 is rotatably arranged on the tool mounting seat; the driving mechanism 5 includes a driving chain belt 50 driving the plurality of transmission gears 120 to rotate synchronously and a rotating motor 51 driving the driving chain belt 50 to move; the driving mechanism 5 also includes a rotating assembly 52 driving the circular cutting tool to rotate and a transverse moving assembly 53 driving the rotating assembly to move and cut the end of the capillary;

[0052] Preferably, a driving gear 510 is provided at the movable end of the rotating motor 51;

[0053] During processing, the clamping component 3 clamps the capillary to fix it, and the lateral movement component 53 drives the rotating component and the circular cutting tool to move as a whole, so that the end of the capillary is located at the center position of multiple cutters. The operation of the rotating motor 51 drives the drive chain belt 50 to rotate, and drives multiple transmission gears 120 to rotate synchronously. Multiple cutters rotate, close and press the capillary 2. Then the rotating component 52 drives the tool mounting seat to rotate for rotary cutting. After rotary cutting, the cutter is reset, and the lateral movement component 53 drives the rotating component and the circular cutting tool to move as a whole to cut off the end of the capillary. The degree of automation is high, no manual intervention is required, the cutting flatness is high, and the processing efficiency and product yield are improved.

[0054] Preferably, a groove 10 for accommodating the end of the capillary 2 is provided on the tool mounting seat at the center of the multiple cutters 12, and a groove 11 for the end of the capillary 2 to enter is provided on one side wall of the groove 10; the transverse movement component 53 drives the circular cutting tool 1 to move radially along the capillary 2; the groove 11 is consistent with the direction of the radial movement of the annular tool 1 along the capillary, and in the initial state, the groove 11 is directly opposite to any gap of the multiple cutters 12; adopting this structural method, the stroke that the transverse movement component 53 needs to drive the rotating component and the circular cutting tool to move as a whole is greatly reduced, which can further improve the positioning accuracy and processing efficiency.

[0055] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
