Description

Technical Field

[0001] This application relates to the technical field of automated sleeve equipment, and in particular to a complete set of needle-guided automatic sleeve numbering tubes. Background Technology

[0002] Currently, in the production of electrical cabinets, control cabinets, and new energy wiring harnesses, each wire requires heat-shrink tubing with a printed number at both ends to identify the wire's connection location and circuit information. Tubing installation is a critical process in wire processing production lines, and its efficiency directly impacts the overall production capacity.

[0003] In actual production, processing tasks in the same batch often involve multiple wire diameters, such as 1.5mm², 2.5mm², 4mm², and 6mm², etc., and different wire diameters require matching number tubes with different inner diameter specifications. In related technologies, a common design approach to process multiple specifications of number tubes is to fix multiple specifications of number tube trays in a side-by-side or array arrangement, while integrating printing, cutting, and other functional components into a single "working head assembly." A two-dimensional motion mechanism (such as an XZ-axis platform) drives this working head assembly to move a wide range on a plane, allowing it to sequentially reach the positions of different specifications of number tubes for processing.

[0004] However, in the above-mentioned scheme, the working head assembly integrates a variety of mechanical, electrical, and pneumatic components, resulting in significant mass and inertia. Driving this working head assembly for high-speed start-stop, long-range reciprocating motion, and precise positioning places high demands on the drive system and control algorithm. Furthermore, the vibrations and impacts generated during movement severely affect the positioning accuracy of the working head assembly, thereby reducing the stability and reliability of station switching and consequently impacting the processing quality of printing, cutting, and other processes.

[0005] Therefore, there is an urgent need for a complete set of automatic number tube inserters with a guide needle. Summary of the Invention

[0006] To improve the efficiency and positioning accuracy of switching between multiple specification number tubes while ensuring processing quality, this application provides a guide needle type automatic number tube fitting machine.

[0007] This application provides a guide needle type automatic number tube issuing machine, which adopts the following technical solution:

[0008] A needle-guided automatic number tube inserter includes:

[0009] The machine frame and a workstation switching mechanism, a processing mechanism and a sleeve mechanism are sequentially arranged on the machine frame. The processing mechanism is used to feed, print and cut the number tubes, and the sleeve mechanism is used to transfer and thread the number tubes.

[0010] The workstation switching mechanism includes a support, a number tube workstation, a drive assembly, and a feeding assembly. The drive assembly and the feeding assembly are respectively mounted on the frame. The support is movably mounted on the frame and connected to the drive assembly. Multiple number tube workstations are provided and arranged along a first direction on the support. The drive assembly is used to drive the support to move along the first direction to move the selected number tube workstation to align with the processing position of the processing mechanism. The feeding assembly is used to feed the number tube on the number tube workstation into the processing position after the number tube workstation is aligned with the processing position.

[0011] By adopting the above technical solution, multiple number tube workstations are centrally arranged on the support. The workstation switching is achieved by driving the support as a whole along the first direction through the drive component. Compared with the existing workhead assembly with a large moving mass, the moving support and number tube workstations have smaller mass and inertia, resulting in faster switching speed and higher positioning accuracy. At the same time, after the workstations are aligned, the feeding component sends the number tube workstations into the processing position, realizing the step-by-step action of workstation switching and feeding. This ensures the accuracy and stability of the number tubes entering the processing position, thereby improving the efficiency and processing quality of switching between multiple specifications of number tubes.

[0012] Optionally, the frame is provided with a mounting plate, and the bracket, the drive assembly and the processing mechanism are respectively mounted on the mounting plate. The number tube station includes a guide block, a clamping module and a guiding module. The guiding module is mounted on the bracket, and the guide block is slidably mounted on the guiding module. One end of the guide block extends toward the processing mechanism. The guide block has a through hole for the number tube to pass through. The clamping module is mounted on the guide block and is used to clamp the number tube.

[0013] The feeding assembly includes a feeding module and a pushing module respectively disposed on the side of the mounting plate opposite to the bracket. One end of the feeding module and the pushing module passes through the mounting plate. The feeding module is used to drive the guide block to move along the guide module to feed the number tube into the processing position. The pushing module is used to drive the clamping module to release the number tube.

[0014] By adopting the above technical solution, the guide block is slidably mounted on the bracket via the guide module. The feeding module drives the guide block to approach the processing mechanism along the guide module, realizing the precise feeding of the number tube from the workstation to the processing position. The clamping module clamps the number tube in the non-processing state to prevent the number tube from falling off or shifting during workstation switching. After the workstation reaches the processing position, the pushing module drives the clamping module to release the number tube, allowing the number tube to enter the feeding state. The feeding module and the pushing module are set on the side of the mounting plate away from the bracket and pass through the mounting plate to act on the guide block and the clamping module, so that the feeding component is fixed and does not move with the bracket, reducing the movement mass of the bracket and improving the speed and accuracy of workstation switching.

[0015] Optionally, one end of the guide block is connected to a traction frame, and the traction frame has a clearance groove on the side near the mounting plate for avoiding the processing mechanism. The number tube passes through the guide block and the clearance groove in sequence.

[0016] The guiding module includes a guide rod and a first elastic element disposed on the guide rod. The guide block is slidably connected to the guide rod and abuts against the first elastic element. The first elastic element is used to push the guide block to move so that the guide block drives the traction frame to move to the side of the processing mechanism away from the mounting plate.

[0017] By adopting the above technical solution, the traction frame extends the guide path of the number tube, enabling it to be guided to the processing mechanism. The clearance groove avoids interference between the traction frame and the processing mechanism, ensuring that the traction frame can smoothly pass through the area where the processing mechanism is located during station switching. The first elastic element pushes the guide block to move in its natural state, keeping the traction frame on the side of the processing mechanism away from the mounting plate. That is, in the non-processing state, the traction frame of the number tube station is far away from the processing area of ​​the processing mechanism, which helps to prevent the number tube from contacting the processing mechanism (such as the feeding wheel) and being torn or detached during station switching, effectively protecting the integrity of the number tube.

[0018] Optionally, a first locking block is provided on the side of the guide block near the bracket, an avoidance groove is provided on the bracket along the first direction, the avoidance groove penetrates the mounting plate, a slide rail is provided on the side of the mounting plate away from the bracket along the first direction, and a reset member is provided at the top of the slide rail;

[0019] The feeding module includes a feeding drive and a second locking block disposed on the feeding drive. The feeding drive is disposed on the side of the mounting plate away from the bracket and connected to the reset component. The second locking block is inserted into the clearance groove. When the number tube station moves to be aligned with the processing position, the second locking block engages with the first locking block.

[0020] By adopting the above technical solution, the engagement of the first and second locking blocks enables rapid docking between the feeding module and the target number tube station. When the target number tube station moves to align with the processing position, the second locking block engages with the first locking block through the clearance groove. The feeding drive can then drive the guide block to move along the guide module through the engagement relationship between the second and first locking blocks, thus realizing the feeding of the number tube station. The clearance groove is opened along the first direction and penetrates the mounting plate, ensuring that the second locking block remains within the clearance groove during the movement of the bracket, without affecting the station switching action. The slide rail and reset component enable the feeding drive to move along the slide rail and automatically reset through the reset component after feeding, ensuring the reliability and repeatability of the feeding action.

[0021] Optionally, the clamping module includes a clamping seat, a second elastic element, and a clamping claw. The clamping claw is disposed on the guide block and close to the through hole. The clamping seat is slidably connected to the clamping claw. The second elastic element is disposed between the clamping seat and the clamping claw. The second elastic element is used to push the clamping seat to squeeze the clamping claw so that the clamping claw clamps the number tube.

[0022] The push module includes a push driver and a push block connected to the push driver. The push driver is mounted on the rack and can push the clamping seat to move in the opposite direction through the push block, so that the gripper releases the number tube.

[0023] By adopting the above technical solution, the gripper is fixedly mounted on the guide block, and the clamping seat is slidably connected to the gripper. The second elastic element pushes the clamping seat to squeeze the gripper, thereby maintaining the clamping of the number tube and effectively preventing the number tube from loosening during vibrations during station switching. Furthermore, the pushing module is fixedly mounted on the frame and does not move with the support. Only after the target station reaches the processing position does the pushing drive push the clamping seat to move in the opposite direction via the pushing block, causing the gripper to release the number tube. This reduces the number and weight of moving parts, simplifies the structure, and improves reliability.

[0024] Optionally, the gripper adopts a cylindrical structure. One end of the gripper is coaxially inserted into the through hole and connected to the guide block. An arc-shaped groove is formed on the outer wall of the other end of the gripper along the circumferential direction. A rectangular hole for the number tube to pass through is formed on the gripper along the axial direction. The rectangular hole is connected to the through hole and the arc-shaped groove respectively. Multiple elastic flaps are arranged in the arc-shaped groove, and the multiple elastic flaps are spaced apart from each other.

[0025] The clamping seat has a sliding groove and a plurality of toothed grooves communicating with the sliding groove. The gripper passes through the sliding groove, and the elastic flap interlocks and meshes with the toothed groove. The clamping seat is provided with a guide surface, and the elastic flap abuts against the guide surface.

[0026] By adopting the above technical solution, the gripper adopts a cylindrical structure with a rectangular hole. The number tube is inserted into the rectangular hole, and multiple elastic flaps are arranged circumferentially in the arc-shaped groove. The elastic flaps apply uniform clamping force to the number tube from multiple directions in the clamping state through the staggered meshing with the toothed grooves on the clamping seat and the contact with the guide surface, forming an approximately square clamping space. Compared with the traditional two-sided flat pressure clamping, the multiple elastic flaps clamp the number tube evenly from multiple directions, so that the cross-section of the number tube is basically kept circular, avoiding the problem of difficulty in inserting the guide needle and tube blockage caused by tube deformation. When the push block pushes the clamping seat to move in the opposite direction, the elastic flaps are released from the constraint of the guide surface and open outward under their own elastic force, releasing the number tube.

[0027] Optionally, the sleeve mechanism includes an adapter assembly and a sleeve assembly respectively disposed on the frame. The adapter assembly is located on the side of the processing mechanism away from the support, and the sleeve assembly is located on the side of the mounting plate away from the processing mechanism. The adapter assembly is used to carry the number tube to a position where it docks with the sleeve assembly after cutting, so as to transfer the number tube onto the sleeve assembly and allow the sleeve assembly to sleeve the number tube onto the wire.

[0028] By adopting the above technical solution, the adapter component and the sleeve component are respectively set on both sides of the processing mechanism. After cutting, the adapter component carries the number tube and moves it to the position where it docks with the sleeve component, realizing the automatic transfer of the number tube from the processing side to the sleeve side. After receiving the number tube, the sleeve component puts it into the wire, completing the fully automated operation of the number tube from cutting to sleeve installation without manual intervention, thus improving processing efficiency and consistency.

[0029] Optionally, the adapter assembly includes a dual-axis drive module and a feeding guide pin. The dual-axis drive module is mounted on the frame, and the feeding guide pin is mounted on the dual-axis drive module. The dual-axis drive module is used to drive the feeding guide pin to transfer between the processing mechanism and the sleeve assembly. The feeding guide pin is used to carry the number tube after cutting.

[0030] The sleeve assembly includes a three-axis drive module, an adapter guide pin, and an auxiliary clamping module. The three-axis drive module and the auxiliary clamping module are respectively mounted on the frame and located on the side of the mounting plate opposite to the processing mechanism. The adapter guide pin is mounted on the three-axis drive module. The auxiliary clamping module is used to clamp the wire to be sleeved. The three-axis drive module is used to drive the adapter guide pin to move so that the adapter guide pin is engaged with the feeding guide pin, transferring the number tube to the adapter guide pin, and causing the adapter guide pin to sleeve the number tube on the wire.

[0031] By adopting the above technical solution, the feeding guide pin carries the number tube after cutting, and the dual-axis drive module drives the feeding guide pin to move to the transfer position; the transfer guide pin achieves precise movement in three directions through the three-axis drive module, which can accurately dock with the feeding guide pin to receive the number tube, and can move to the auxiliary clamping module to put the number tube on the wire; the auxiliary clamping module clamps the wire, providing a stable positioning reference for the placement of the number tube; through the cooperation of the feeding guide pin and the transfer guide pin, the number tube is transferred by the guide pin, and the number tube is always put on the guide pin for transfer, thereby avoiding the number tube from falling off or deforming during the transfer process.

[0032] Optionally, the dual-axis drive module includes an X-axis drive component and a first Y-axis cylinder mounted on the X-axis drive component. The X-axis drive component is mounted on the frame, and both ends of the X-axis drive component extend to both sides of the mounting plate. A first adjusting block is mounted on the first Y-axis cylinder, and a first fixing block is mounted on the X-axis drive component. The feeding guide pin passes through the first fixing block and is connected to the first adjusting block. One end of the first adjusting block extends along the length direction of the feeding guide pin.

[0033] The three-axis drive module includes a Y-axis drive, a Z-axis drive, and a second Y-axis cylinder. The Y-axis drive is mounted on the frame and located on the side of the mounting plate opposite to the processing mechanism. The Z-axis drive is mounted on the Y-axis drive. The second Y-axis cylinder is mounted on the Z-axis drive and has a second adjusting block. The adapter guide pin is mounted on the second adjusting block and slidably connected to the Z-axis drive. One end of the second adjusting block extends along the length of the adapter guide pin. When the adapter guide pin aligns with the feeding guide pin, the first adjusting block and the second adjusting block engage to limit the safe distance between the adapter guide pin and the feeding guide pin.

[0034] By adopting the above technical solution, the X-axis drive and the first Y-axis cylinder cooperate to drive the feeding guide pin to move, enabling the feeding guide pin to be transferred between the processing mechanism and the sleeve assembly. The Y-axis drive, Z-axis drive, and second Y-axis cylinder achieve precise movement of the transfer guide pin in three directions, ensuring accurate alignment between the transfer guide pin and the feeding guide pin. The first adjusting block and the second adjusting block abut against each other when docking, limiting the safe distance between the feeding guide pin and the transfer guide pin, thereby effectively avoiding the bending or damage of the pin tips caused by the collision of the two guide pin tips, improving the reliability of the transfer process and the service life of the equipment.

[0035] Optionally, a second fixing block is provided on the frame, and a limit plate is provided on the second adjusting block. When the adapter guide pin is connected to the wire on the auxiliary clamping module, the second fixing block abuts against the limit plate.

[0036] By adopting the above technical solution, the contact cooperation between the second fixing block and the limiting plate limits the extreme position of the adapter guide pin moving towards the wire, so that when the Y-axis drive unit drives the Z-axis drive unit to move towards the wire, the adapter guide pin does not move, and the Z-axis drive unit drives the number tube on the adapter guide pin to move, thereby facilitating the placement of the number tube on the wire.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. By arranging multiple number tube workstations on a support and driving the support to move, the workstation switching is achieved. Compared with the solution of moving the workhead assembly, the motion mass is small, the switching speed is fast, and the positioning accuracy is high. Combined with the step-by-step feeding action of the feeding component, the accuracy and stability of the number tube entering the processing position are guaranteed.

[0039] 2. By limiting the safe distance between the feeding guide pin and the transfer guide pin through the docking of the first and second adjusting blocks, collisions between the feeding guide pin and the transfer guide pin are effectively avoided, thereby improving the reliability of the transfer and the service life of the equipment.

[0040] 3. The first elastic element pushes the guide block away from the processing mechanism when the device is not being processed, thus preventing the number tube from coming into contact with the processing mechanism and being torn or falling off during the workstation switching process; the meshing structure of the elastic petals and the tooth grooves achieves uniform clamping in multiple directions, thus preventing the number tube from deforming and becoming blocked.

Detailed Implementation

[0051] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0052] This application discloses a guide needle type automatic number tube machine.

[0053] It should be noted that, in the description of this invention, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0054] Reference Figure 1 An automatic number tube inserting machine with a guide needle type includes a frame 1 and a station switching mechanism 2, a processing mechanism 3, and a tube inserting mechanism 4 sequentially arranged on the frame 1. The station switching mechanism 2 is used to switch between number tubes of different specifications, the processing mechanism 3 is used to feed, print, and cut the number tubes, and the tube inserting mechanism 4 is used to transfer and insert the number tubes.

[0055] Reference Figure 1 and Figure 2 A mounting plate 11 is installed on the frame 1. The workstation switching mechanism 2 includes a bracket 21, a number tube workstation 22, a drive assembly 23, and a feeding assembly 24. The drive assembly 23 and the feeding assembly 24 are respectively located on both sides of the mounting plate 11. The bracket 21 is slidably connected to the mounting plate 11 along a first direction and is connected to the drive assembly 23. An clearance groove 211 is formed on the bracket 21 along the first direction, penetrating the mounting plate 11. In this embodiment, the first direction is vertical, and the drive assembly 23 is a lead screw motor. The output end of the lead screw motor is connected to the bracket 21, driving the bracket 21 to move up and down vertically.

[0056] Multiple number tube stations 22 are provided; in this embodiment, six are provided. The six number tube stations 22 are arranged along the first direction on the support 21, and each number tube station 22 corresponds to loading a number tube tray of a certain specification (not shown in the figure). The number tube tray is set on the frame 1, and the number tubes are led out from the number tube tray and pass through the number tube station 22. The number tube station 22 includes a guide block 221, a clamping module 222, and a guiding module 223.

[0057] Reference Figure 1 and Figure 3 The guide module 223 includes a guide rod 2231 and a first elastic element 2232 disposed on the guide rod 2231. Each guide block 221 is slidably connected to two guide rods 2231, and one end of the guide block 221 extends towards the processing mechanism 3. The guide block 221 has a through hole 2211 for the number tube to pass through. In this embodiment, the first elastic element 2232 is a spring. The first elastic element 2232 is sleeved on the guide rod 2231, one end of the first elastic element 2232 abuts against the guide block 221, and the other end abuts against the bracket 21. In its natural state, the first elastic element 2232 pushes the guide block 221 away from the bracket 21.

[0058] A first locking block 2212 is fixedly connected to the side of the guide block 221 near the bracket 21. A traction frame 224 is connected to the end of the guide block 221 near the processing mechanism 3. A clearance groove 2241 for avoiding the processing mechanism 3 is opened on the side of the traction frame 224 near the mounting plate 11. The number tube is sequentially set through the through hole 2211 of the guide block 221 and the clearance groove 2241 of the traction frame 224. The opening of the clearance groove 2241 allows the traction frame 224 to avoid the functional components of the processing mechanism 3 when passing through the area where the processing mechanism 3 is located, thus avoiding interference.

[0059] Reference Figure 2 and Figure 4 The feeding assembly 24 includes a feeding module 241 and a pushing module 242 respectively disposed on the side of the mounting plate 11 away from the bracket 21. The feeding module 241 includes a feeding drive 2411 and a second locking block 2412 disposed on the feeding drive 2411. The feeding drive 2411 is disposed on the side of the mounting plate 11 away from the bracket 21, and the second locking block 2412 is inserted into the clearance groove 211.

[0060] In this embodiment, the feeding drive 2411 is a cylinder, and the end of the feeding drive 2411 away from the guide block 221 is connected to a slide plate 2413. The side of the mounting plate 11 away from the bracket 21 is provided with a slide rail along the first direction. The slide plate 2413 is slidably connected to the slide rail, so that the feeding drive 2411 can slide along the slide rail.

[0061] A reset member 2414 is provided at the top of the slide rail, and the reset member 2414 is connected to the feed drive member 2411. In this embodiment, the reset member 2414 is a reset spring, which keeps the feed drive member 2411 in its original position and allows the feed drive member 2411 to reset after movement.

[0062] Reference Figure 2 and Figure 3 During the process of the drive assembly 23 driving the support 21 to move, causing the target guide block 221 to move to be aligned with the processing position, the drive component 2411 is fed in (see reference). Figure 4 The second locking block 2412 is moved closer to the bracket 21, so that it is positioned to engage with the first locking block 2212. After the target guide block 221 moves to the designated position, the first locking block 2212 engages with the second locking block 2412. At this time, the feeding drive 2411 can drive the guide block 221 to move through the second locking block 2412 and the first locking block 2212. This causes the guide block 221 to overcome the elastic force of the first elastic member 2232 and move along the guide rod 2231 closer to the bracket 21. The guide block 221 drives the traction frame 224 to move, so as to feed the number tube on the traction frame 224 to the processing position.

[0063] Reference Figure 1 and Figure 2 To prevent the number tube from shifting position due to being pulled by the processing mechanism 3 during feeding, the number tube does not contact the processing mechanism 3 when it is initially fed into the processing position. At this time, the drive assembly 23 drives the bracket 21 to move downwards, and the bracket 21 drives the guide block 221 and the traction frame 224 to move, so that the number tube contacts the processing mechanism 3, thereby completing the feeding of the number tube. During this process, due to the first locking block 2212 (refer to...) Figure 3 The friction between the first block and the second block 2412 guides the movement of the guide block 221, which in turn drives the feed drive 2411 (see reference). Figure 4 The tube is moved to ensure the stability of the number tube position during the feeding process.

[0064] Reference Figure 3 and Figure 4 After feeding is completed, the feeding drive 2411 reverses its operation, causing the first card block 2212 and the second card block 2412 (see reference) to... Figure 2 ) disengages, first elastic element 2232 (refer to) Figure 1 The guide block 221 is pushed back to its initial position, and the reset component 2414 is driven to move the drive component 2411 along the slide rail to reset.

[0065] Reference Figure 1 and Figure 3 The clamping module 222 includes a clamping base 2221, a second elastic element 2222, and a clamping claw 2223. The clamping claw 2223 adopts a cylindrical structure. One end of the clamping claw 2223 is coaxially inserted into the tube hole 2211 and connected to the guide block 221, ensuring the coaxiality between the clamping claw 2223 and the tube hole 2211, so that the number tube can smoothly pass through the clamping claw 2223 and enter the tube hole 2211.

[0066] The gripper 2223 has a rectangular hole 2224 along its axial direction for the number tube to pass through, and the rectangular hole 2224 communicates with the tube hole 2211. An arc-shaped groove 2225 is formed circumferentially on the outer wall surface of the end of the gripper 2223 away from the tube hole 2211, and the arc-shaped groove 2225 communicates with the rectangular hole 2224. Multiple elastic flaps 2226 are arranged within the arc-shaped groove 2225, and the multiple elastic flaps 2226 are spaced apart from each other.

[0067] The clamping base 2221 has a sliding groove 2227, through which the gripper 2223 passes, allowing the clamping base 2221 to slide in a direction perpendicular to the axis of the gripper 2223. The clamping base 2221 also has multiple toothed grooves 2228 communicating with the sliding groove 2227, with elastic flaps 2226 interlocking and meshing with the toothed grooves 2228. The clamping base 2221 is provided with a guide surface 2229, with the elastic flaps 2226 abutting against the guide surface 2229. In this embodiment, the guide surface 2229 is V-shaped.

[0068] The second elastic element 2222 is disposed in the slide groove 2227 and connected to the clamping seat 2221 and the gripper 2223 respectively. In this embodiment, the second elastic element 2222 is a spring. The second elastic element 2222 is used to push the clamping seat 2221 to squeeze the gripper 2223.

[0069] In the clamping state, the second elastic element 2222 pushes the clamping seat 2221 to move in a direction perpendicular to the axis of the jaw 2223, causing the guide surface 2229 on the clamping seat 2221 to gradually press against the elastic flap 2226. This causes the elastic flap 2226 to converge towards the rectangular hole 2224 along the guide surface 2229, cooperating with the rectangular hole 2224 to form an approximately square clamping space. This applies a uniform clamping force to the number tube from multiple directions, ensuring that the cross-section of the number tube remains essentially circular. Compared to traditional two-sided flat-pressure clamping, multiple elastic flaps 2226 clamp the number tube uniformly from multiple directions, avoiding difficulties in needle insertion and tube blockage caused by tube deformation. The toothed structure of the elastic flap 2226 increases the friction between it and the number tube, preventing axial sliding of the number tube in the clamping state.

[0070] Reference Figure 2 and Figure 4 The pushing module 242 includes a pushing drive 2421 and a pushing block 2422 connected to the pushing drive 2421. The pushing drive 2421 is mounted on the mounting plate 11. In this embodiment, the pushing drive 2421 is a cylinder. When the target guide block 221 moves to the processing position, the pushing drive 2421 drives the pushing block 2422 to push the clamping seat 2221 to move away from the bracket 21, so that the elastic flap 2226 opens outward under its own elastic force, releasing the number tube, and the number tube enters the feeding state. After the pushing drive 2421 resets, the pushing block 2422 retracts, the second elastic element 2222 pushes the clamping seat 2221 back to the clamping position, and the elastic flap 2226 retracts along the guide surface 2229, restoring the clamping state of the number tube.

[0071] The processing mechanism 3 includes a feeding guide assembly 31, a print head 32, a ribbon winding assembly 33, and a cutting assembly 34. The feeding guide assembly 31 and the print head 32 are sequentially arranged on the mounting plate 11, and the feeding guide assembly 31 is located between the print head 32 and the bracket 21.

[0072] Reference Figure 1 and Figure 2The feeding guide assembly 31 includes a main shaft driven by a drive unit and a transmission shaft linked to the main shaft via a first transmission belt. Feeding rollers are fixedly mounted on both the main shaft and the transmission shaft. A limiting wheel rotates in contact with the feeding roller on the main shaft, and the print head 32 abuts against the feeding roller on the transmission shaft. After the number tube is fed out from the guide block 221, it passes sequentially between the feeding roller and the limiting wheel, and between the feeding roller on the transmission shaft and the print head 32. When the drive unit is activated, the main shaft rotates and drives the transmission shaft to rotate synchronously via the first transmission belt. The two feeding rollers work together to convey the number tube forward to the sleeve mechanism 4. It should be noted that the processing position in this embodiment refers to the location of the inlet of the feeding guide assembly 31.

[0073] The printhead 32 is a thermal transfer printhead, and the ribbon winding assembly 33 includes a ribbon feed tray and a ribbon return tray. The ribbon on the feed tray wraps around the working area of ​​the printhead 32 and is finally wound onto the ribbon return tray. As the number tube is fed forward, the printhead 32 prints preset characters or numbers on the number tube. The ribbon return tray is mechanically linked to the drive shaft, which provides rotational power to the ribbon return tray while feeding the number tube, thus achieving active recycling of waste ribbon and ensuring that the ribbon maintains appropriate tension during the printing process.

[0074] After the number tube is fed to a predetermined length and printing is completed, the cutting component 34 actuates to cut the number tube. The cutting component 34 can adopt an upper and lower cutting blade structure, and the cutting blade is driven to close by a driving component such as a claw cylinder to cut the number tube.

[0075] Reference Figure 1 The sleeve mechanism 4 includes a transfer assembly 41 and a sleeve assembly 42 respectively mounted on the frame 1. The transfer assembly 41 is located on the side of the cutting assembly 34 away from the bracket 21. The sleeve assembly 42 is located on the side of the mounting plate 11 away from the processing mechanism 3.

[0076] Reference Figure 1 and Figure 7 The transfer assembly 41 includes a dual-axis drive module 411 and a feeding guide pin 412. The dual-axis drive module 411 is mounted on the frame 1. The feeding guide pin 412 is mounted on the dual-axis drive module 411. The dual-axis drive module 411 drives the feeding guide pin 412 to transfer between the cutting assembly 34 and the sleeve assembly 42. The feeding guide pin 412 is used to carry the number tube after cutting.

[0077] The dual-axis drive module 411 includes an X-axis drive component 4111 and a first Y-axis cylinder 4112 mounted on the X-axis drive component 4111. The X-axis drive component 4111 is mounted on the frame 1, and its two ends extend to both sides of the mounting plate 11. In this embodiment, the X-axis drive component 4111 adopts a motor lead screw structure to drive the first Y-axis cylinder 4112 to move between the cutting assembly 34 and the sleeve assembly 42.

[0078] A first adjusting block 4113 is fixedly connected to the first Y-axis cylinder 4112. A first fixing block 4114 is fixedly connected to the X-axis drive unit 4111. The feed guide pin 412 passes through the first fixing block 4114 and is fixedly connected to the first adjusting block 4113. One end of the first adjusting block 4113 extends along the length direction of the feed guide pin 412.

[0079] After the processing mechanism 3 feeds and prints the number tube, the number tube is sent to the feeding guide pin 412. The cutting component 34 cuts the number tube, and the cut number tube segment remains on the feeding guide pin 412. The X-axis drive component 4111 drives the feeding guide pin 412 to move horizontally from the side where the cutting component 34 is located to the transition position where the sleeve assembly 42 is located.

[0080] Reference Figure 1 and Figure 8 The sleeve assembly 42 includes a three-axis drive module 421, an adapter guide pin 422, and an auxiliary clamping module 423. The three-axis drive module 421 and the auxiliary clamping module 423 are respectively mounted on the frame 1 and located on the side of the mounting plate 11 opposite to the machining mechanism 3. The adapter guide pin 422 is mounted on the three-axis drive module 421.

[0081] The three-axis drive module 421 includes a Y-axis drive unit 4211, a Z-axis drive unit 4212, and a second Y-axis cylinder 4213. The Y-axis drive unit 4211 is mounted on the frame 1 and located on the side of the mounting plate 11 opposite to the machining mechanism 3. The Z-axis drive unit 4212 is mounted on the Y-axis drive unit 4211. The second Y-axis cylinder 4213 is mounted on the Z-axis drive unit 4212. A second adjusting block 4214 is provided on the second Y-axis cylinder 4213. An adapter guide pin 422 is mounted on the second adjusting block 4214 and slidably connected to the Z-axis drive unit 4212. One end of the second adjusting block 4214 extends along the length direction of the adapter guide pin 422.

[0082] When it is necessary to mate the adapter guide pin 422 with the feeding guide pin 412, the X-axis drive unit 4111 drives the feeding guide pin 412 to move horizontally from the side where the cutting assembly 34 is located to the adapter position where the sleeve assembly 42 is located. The Y-axis drive unit 4211 drives the Z-axis drive unit 4212 and the second Y-axis cylinder 4213 to approach the feeding guide pin 412. At the same time, the Z-axis drive unit 4212 drives the second Y-axis cylinder 4213 and the adapter guide pin 422 to rise and fall, so that the adapter guide pin 422 mates with the feeding guide pin 412.

[0083] When the adapter guide pin 422 and the feeding guide pin 412 approach and mate, the extended ends of the first adjusting block 4113 and the second adjusting block 4214 abut against each other, thereby limiting the minimum distance between the tips of the adapter guide pin 422 and the feeding guide pin 412, ensuring that the two guide pins will not collide.

[0084] After the adapter guide pin 422 aligns with the feeding guide pin 412, the first Y-axis cylinder 4112 stops working, and the second Y-axis cylinder 4213 drives the adapter guide pin 422 to move towards the feeding guide pin 412. This causes the second adjusting block 4214 to push the first adjusting block 4113 away from the frame 1, and the first adjusting block 4113 drives the feeding guide pin 412 to move. During this process, the number tube on the feeding guide pin 412 abuts against the first fixing block 4114, keeping the number tube stationary while the feeding guide pin 412 continues to move. At the same time, the second adjusting block 4214 drives the adapter guide pin 422 to move, transferring the number tube onto the adapter guide pin 422.

[0085] After the transfer is completed, the three-axis drive module 421 drives the adapter guide pin 422 to move to the auxiliary clamping module 423. The auxiliary clamping module 423 uses a cylinder gripper to clamp the wire to be sleeved, with only the end to be sleeved exposed, and the tip of the adapter guide pin 422 is aligned with the end of the wire.

[0086] Reference Figure 4 and Figure 8 The frame 1 is equipped with a second fixing block 12, and the second adjusting block 4214 is equipped with a limiting plate 4215. When it is necessary to transfer the number tube to the wire end, the adapter pin 422 is first connected to the wire on the auxiliary clamping module 423. Then, the second Y-axis cylinder 4213 stops working, and the Y-axis drive 4211 drives the Z-axis drive 4212 to move closer to the auxiliary clamping module 423, so that the second fixing block 12 abuts against the limiting plate 4215. At this time, the second adjusting block 4214 and the adapter pin 422 can no longer move towards the auxiliary clamping module 423, while the Y-axis drive 4211 continues to drive the Z-axis drive 4212 to move, so that the Z-axis drive 4212 pushes the number tube on the adapter pin 422 to move, so as to put the number tube on the wire end.

[0087] The implementation principle of the automatic number tube feeding machine of this application embodiment is as follows: The controller, according to the task instruction, causes the drive component 23 to move the support 21 up and down, moving the number tube station 22 containing the target specification number tube to the processing position. At this time, the first locking block 2212 on the guide block 221 engages with the second locking block 2412. The feed drive component 2411 is activated, pulling the guide block 221 towards the support 21 to feed the number tube into the inlet of the processing mechanism 3. Simultaneously, the push drive component 2421 pushes the clamping seat 2221 to move in the opposite direction through the push block 2422, causing the elastic flap 2226 to open and release the number tube. Next, the feeding guide component 31 conveys the number tube to the print head 32. After being printed by the print head 32, the number tube is conveyed to the cutting component 34. Before cutting, the feed guide pin 412 moves into position and inserts into the number tube. The cutting component 34 operates, and the cut number tube segment remains on the feed guide pin 412.

[0088] Next, the X-axis drive unit 4111 drives the feed guide pin 412 with the number tube to translate to the transfer position, and the three-axis drive module 421 drives the transfer guide pin 422 to move to dock with the feed guide pin 412. At the same time, the extension ends of the first adjusting block 4113 and the second adjusting block 4214 abut against each other.

[0089] After alignment, the second Y-axis cylinder 4213 drives the transfer guide pin 422 forward, causing the second adjusting block 4214 to push the first adjusting block 4113 to move away from the frame 1. The first adjusting block 4113 drives the feeding guide pin 412 to move. During this process, the number tube on the feeding guide pin 412 abuts against the first fixed block 4114. The number tube does not move, while the feeding guide pin 412 continues to move. At the same time, the second adjusting block 4214 drives the transfer guide pin 422 to move, so as to transfer the number tube to the transfer guide pin 422.

[0090] The three-axis drive module 421 drives the adapter guide pin 422 with the number tube to move to the auxiliary clamping module 423, aligning it with the clamped wire. During sleeve application, the limiting plate 4215 of the second adjusting block 4214 on the adapter guide pin 422 abuts against the second fixing block 12 on the frame 1, preventing the adapter guide pin 422 from advancing. At this time, the Y-axis drive unit 4211 continues to drive the Z-axis drive unit 4212 forward, causing the Z-axis drive unit 4212 to push the number tube on the adapter guide pin 422 to move, so as to sleeve the number tube on the end of the wire, completing the sleeve application operation.

[0091] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
