[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0028] Referring to Figures 1-8 , the present invention provides a fixed-length tube cutting and inserting mechanism, including a support frame (not shown in the figure), the support frame plays a role of fixing and supporting the overall device, and multiple groups of cutting mechanisms are arranged on the support frame; the cutting mechanism includes a discharging component 1, a cutting component 2, and a fixed-length component 3 arranged on the support frame; the discharging component 1 is used for outputting the tube to be cut;

[0029] The cutting component 2 includes a cutting table 4 fixedly connected to the support frame. A through hole for the tube to pass through is provided on the cutting table 4, and a cutting groove 5 communicated with the through hole is provided on the side wall of the cutting table 4. A driving component 6 is arranged on the support frame, and the output end of the driving component 6 is fixedly connected with a cutter 7. The driving component 6 drives the cutter 7 to slide in the cutting groove 5;

[0030] In this embodiment, the driving component 6 includes a cylinder fixedly connected to the support frame, and the output end of the cylinder is fixedly connected with the cutter 7; it is suitable for fixed-length cutting of flexible tubes such as PU tubes, silicone tubes, and PVC tubes;

[0031] The fixed-length component 3 includes a first linear reciprocating component 8 arranged on the support frame. The moving end of the first linear reciprocating component 8 moves along the axial direction of the through hole. A clamping jaw component is arranged at the moving end of the first linear reciprocating component 8. A first sensor 9 is fixedly connected to the support frame. The first sensor 9 is used to detect whether the end of the tube reaches the specified position. The first sensor 9 and the clamping jaw component are respectively located at one end of the cutting table 4 away from the discharging component 1;

[0032] When the end of the tube is conveyed to the position of the first sensor 9, the first sensor 9 detects the tube and transmits a signal to the controller, which controls the gripper assembly to start clamping the tube.

[0033] The tube is conveyed to the cutting table 4 of the cutting assembly 2 through the discharging assembly 1. The tube passes through the through-hole on the cutting table 4 and passes through the gripper assembly. When the end of the tube reaches the position of the first sensor 9, the gripper assembly clamps the tube, and drives the gripper assembly to move away from the cutting table 4 through the first linear reciprocating assembly 8, so as to stretch the tube. When the stretching reaches the specified length, the first linear reciprocating assembly 8 stops, and the driving assembly 6 drives the cutter 7 to extend into the cutting groove 5 to cut the tube, thereby realizing the fixed-length cutting of the tube. After the cutting is completed, the first linear reciprocating assembly 8 drives the gripper assembly to continue to move, so that the tube extends out of the through-hole, which is convenient for taking out and collecting the tube. In this application, the initial position of the tube can be detected by the first sensor 9, and the tube can be stretched to different lengths through the first linear reciprocating assembly, so as to realize the cutting of tubes with different specifications and lengths, and improve the convenience of using the device.

[0034] In a further optimized solution, an intubation mechanism 22 is also provided. The intubation mechanism 22 includes a second linear reciprocating assembly 10 fixed on the support frame. The moving end of the second linear reciprocating assembly 10 is fixedly connected with a third linear reciprocating assembly 11. The moving end of the third linear reciprocating assembly 11 is fixedly connected with an intubation platform 12. A plurality of insertion holes are formed on the intubation platform 12. The moving end of the first linear reciprocating assembly 8 moves along the Z-axis direction, and the moving ends of the second linear reciprocating assembly 10 and the third linear reciprocating assembly 11 move along the X-axis and Y-axis directions respectively.

[0035] The first linear reciprocating assembly 8, the second linear reciprocating assembly 10, and the third linear reciprocating assembly 11 include but are not limited to linear motors and motor lead screw structures. In this embodiment, they are all motor lead screw structures, that is, including a sliding seat, a motor is fixedly connected to the sliding seat, a lead screw is fixedly connected to the output shaft of the motor, a slider is threadedly sleeved on the lead screw, and the slider slides on the sliding seat as the moving end. Specifically, it is the prior art and will not be elaborated here.

[0036] After the tube is cut, the first linear reciprocating assembly 8 drives the gripper assembly to descend, so as to drive the tube above the intubation platform 12. The second linear reciprocating assembly 10 and the third linear reciprocating assembly 11 drive the intubation platform 12 to move, so that the tube is aligned with the insertion holes on the intubation platform 12, and then the tube is inserted into the insertion holes to realize the centralized collection of the tubes and avoid the scattering of the tubes.

[0037] For a further optimized solution, the jaw assembly includes a pipe-gripping air jaw 13 fixedly connected to the moving end of the first linear reciprocating assembly 8. On each of the two sliding platforms of the pipe-gripping air jaw 13, a first clamping plate 14 is fixedly connected. On one side of the two first clamping plates 14 facing each other, a first semi-circular groove is respectively formed, and the radius of the first semi-circular groove is smaller than the radius of the pipe.

[0038] The moving end of the first linear reciprocating assembly 8 is also fixedly connected with a pipe-guiding air jaw 15. The pipe-guiding air jaw 15 is located at one end of the pipe-gripping air jaw 13 away from the cutting table 4. On each of the two sliding platforms of the pipe-guiding air jaw 15, a second clamping plate 16 is fixedly connected. On one side of the two second clamping plates 16 facing each other, a second semi-circular groove is respectively formed, and the radius of the second semi-circular groove is larger than the radius of the pipe.

[0039] The pipe-gripping air jaw 13 and the pipe-guiding air jaw 15 have the same model, both being hfz16n. The radius of the first semi-circular groove on the two first clamping plates 14 on the pipe-gripping air jaw 13 is smaller than the radius of the pipe. Therefore, when the two first clamping plates 14 come into contact and close, the two first semi-circular grooves can clamp the pipe.

[0040] The radius of the second semi-circular groove on the two second clamping plates 16 on the pipe-guiding air jaw 15 is larger than the radius of the pipe. Therefore, when the two second clamping plates 16 come into contact and close, it can enable the pipe to smoothly pass through the space formed by the combination of the two second semi-circular grooves, playing a guiding role.

[0041] For a further optimized solution, the discharging assembly 1 includes a discharging roller 17 rotatably connected to the support frame. The discharging roller 17 is used for installing a rolled pipe. On the support frame, a V-shaped wheel 18 and a driven wheel are rotatably connected relatively. The V-shaped wheel 18 is located between the discharging roller 17 and the cutting table 4. A pipe-feeding motor is fixedly connected to the support frame, and the output shaft of the pipe-feeding motor is fixedly connected to the V-shaped wheel 18.

[0042] The pipe-feeding motor drives the V-shaped wheel 18 to rotate, thereby driving the pipe between the V-shaped wheel 18 and the driven wheel forward through friction, realizing the stretching and discharging of the pipe.

[0043] For a further optimized solution, a second sensor 19 is fixedly connected to the support frame. The second sensor 19 is located on one side of the V-shaped wheel 18 close to the discharging roller 17; the second sensor 19 is used to detect whether there is a pipe in front of the V-shaped wheel 18. When there is no pipe, it indicates that the pipe on the discharging roller 17 has been used up and needs to be replaced.

[0044] For a further optimized solution, two pipe-guiding wheels 20 are also rotatably connected to the support frame. The two pipe-guiding wheels 20 are arranged relatively. The pipe-guiding wheels 20 are located between the discharging roller 17 and the V-shaped wheel 18, playing a guiding role.

[0045] For a further optimized solution, a pipe-guiding pipe 21 is fixedly connected to one end of the cutting table 4 close to the V-shaped wheel 18. The pipe-guiding pipe 21 is communicated with the through hole.

[0046] When the utility model is in use, the tube on the discharging roller 17 is led out and sequentially passes through the tube guiding wheel 20, the second sensor 19 for feeding, and the V-shaped wheel 18. The V-shaped wheel 18 is driven by the tube feeding motor to rotate, and the tube is frictionally conveyed into the tube guiding pipe 21. Through the setting of the transmission parameters of the tube feeding motor, the tube is conveyed from the tube guiding pipe 21 to the inner position of the through hole formed by the enclosure of two second semi-circular grooves on the tube guiding air claw 15. At this time, the first linear reciprocating assembly 8 makes the tube clamping air claw 13 and the tube guiding air claw 15 move downward. At the same time, the tube moves downward together with the tube feeding motor. When it moves above the first sensor 9, the tube clamping air claw 13 and the tube guiding air claw 15 stop moving, and the tube continues to move downward through the tube feeding motor. The tube emerges from below the tube guiding air claw 15. After the first sensor 9 senses the tube emerging from the tube guiding air claw 15, the tube clamping air claw 13 clamps the tube. The tube clamping air claw 13, the tube guiding air claw 15, and the tube continue to move downward simultaneously until they reach the set tube length position. The cutter 7 is driven by the driving assembly 6 to cut the tube. The tube clamping air claw 13, the tube guiding air claw 15, and the cut tube continue to move downward to a certain height and stop moving. The tube inserting platform 12 moves through the second linear reciprocating assembly 10 and the third linear reciprocating assembly 11 to align the insertion hole with the center position of the tube. The tube clamping air claw 13 and the tube guiding air claw 15 move downward to insert the cut tube into the hole of the tube inserting platform 12. After inserting one tube, the tube clamping air claw 13 and the tube guiding air claw 15 release the tube and move upward. The tube inserting platform 12 moves to the next tube feeding position, and the same tube feeding mechanism inserts the next tube into another hole.

[0047] The utility model precisely feeds the tube through a servo motor, can identify abnormal thickness or thinness of the tube, and prompts the operator to handle the tube with abnormal dimensions through an alarm. The cutter realizes the cutting of the pipe material through the driving assembly, and the control system can perform precise control according to the cutting parameters to achieve fast and precise cutting operations. This mechanism is composed of multiple groups spliced together, with a compact structural space, realizing the cutting of tubes with different length specifications within a limited space range and inserting them into the corresponding holes in an orderly manner, facilitating the operator to quickly identify the tubes and take them.
