Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable processing equipment, in particular to an automatic offline and heat shrink sleeve marking and pipe penetrating heat shrink integrated machine. BACKGROUND

[0002] In the production and manufacturing process of wire harness products, the fixed-length offline of the wire, the identification printing and the heat shrink sleeve penetrating are core pre-processes, and the processing quality and efficiency directly affect the operation precision and production rhythm of subsequent welding, crimping and other processes, and have a key influence on the assembly quality and production efficiency of the entire wire harness product. At present, the industry still mostly adopts the traditional manual operation mode for the above-mentioned wire processing procedures, that is, the fixed-length offline of the wire is completed by hand, and the heat shrink sleeve is manually penetrated. The manual offline processing precision is poor and the consistency is insufficient, the manual heat shrink sleeve penetrating operation efficiency is low and the error rate is high, which leads to high production cost and low efficiency.

[0003] Secondly, the existing technology also adopts an inkjet printing method to print marks on the heat shrink sleeve to realize length control and identity recognition of the wire, so as to facilitate subsequent operation personnel to quickly distinguish the corresponding workstations of the wires and improve the welding and crimping operation efficiency. However, the inkjet printing heat shrink sleeve has unstable printing quality, is prone to artifacts and other problems during the printing process, and has a relatively slow printing speed and poor batch printing capacity, which is difficult to meet the demand of a large amount of printing.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] A specific embodiment of the present invention provides an automatic heat shrink tubing unloading, marking and inserting heat shrink tubing integrated machine, including a heat shrink tubing unloading mechanism 1, a heat shrink tubing marking mechanism 2, a heat shrink tubing cutting mechanism 3, a heat shrink tubing transfer mechanism 4, a heat shrink tubing heating mechanism 5, a wire cutting mechanism 6, a wire feeding mechanism 7, and a wire output mechanism 8. Combined with appendix Figure 1 and attached Figure 2 As shown, the heat shrink tubing marking mechanism 2 is located on one side of the heat shrink tubing travel path between the heat shrink tubing feeding mechanism 1 and the heat shrink tubing cutting mechanism 3. The heat shrink tubing feeding mechanism 1 is used to feed the entire reel of heat shrink tubing, and therefore includes components such as a material tray guide wheel; the heat shrink tubing marking mechanism 2 is used to mark the heat shrink tubing, and the heat shrink tubing cutting mechanism 3 is used to cut the heat shrink tubing to a fixed length. The heat shrink tubing transfer mechanism 4 is located on the side away from the heat shrink tubing cutting mechanism 3 of the heat shrink tubing feeding mechanism 1. The heat shrink tubing transfer mechanism 4 is located between the heat shrink tubing cutting mechanism 3 and the heat shrink tubing heating mechanism 5. The heat shrink tubing transfer mechanism 4 can transfer the heat shrink tubing at the cutting station of the heat shrink tubing cutting mechanism 3 to the heat shrink station of the heat shrink tubing heating mechanism 5. The heat shrink tubing heating mechanism 5 is used to heat the heat shrink tubing sleeved on the wire, thereby completing the heat shrinking. The wire cutting mechanism 6 is located between the heat shrink tubing heating mechanism 5 and the wire feeding mechanism 7. The wire feeding mechanism 7 is used to transport the wire, and the wire cutting mechanism 6 is used to cut the wire. The wire exit mechanism 8 is located on the side of the heat shrink tubing heating mechanism 5 away from the wire cutting mechanism 6. The wire exit mechanism 8 is used to unload the heat-shrinked wire.

[0022] The automatic heat shrink tubing marking and insertion machine provided in this application enables a fully automated process for heat shrink tubing, from material preparation, marking, cutting, transfer, heating to wire feeding, cutting, and final product unloading. The collaborative operation of all mechanisms within this integrated machine significantly improves production efficiency, reduces the tediousness and errors of manual operation, ensures product quality stability and consistency, effectively lowers production costs, and is suitable for large-scale industrial production needs.

[0023] In a specific embodiment of this application, the wire feeding mechanism 7 includes a wire feeding drive assembly 9, a wire straightening assembly 10, and a wire detection sensor 11. The wire straightening assembly 10 is disposed on one side of the wire detection sensor 11, and the wire feeding drive assembly 9 is disposed on the other side. The wire feeding drive assembly 9 is used to actively feed the wire, the wire straightening assembly 10 is used to straighten the wire, and the wire detection sensor 11 is disposed on one side of the wire to detect knots in the wire.

[0024] The specific wire feeding drive assembly 9 includes a wire clamping wheel set 12, a drive wire clamping wheel set 13, a wire clamping cylinder 14, a timing belt set 15, and a guide member 16. Both the wire clamping wheel set 12 and the drive wire clamping wheel set 13 are a pair of wire clamping wheels. One of the wire clamping wheels in each set is mounted on a first mounting portion 17, and the other wire clamping wheel is mounted on a second mounting portion 18. The wire clamping wheels on the first mounting portion 17 and the second mounting portion 18 are correspondingly arranged. The wire clamping cylinder 14 is connected to the first mounting portion 17, and the first mounting portion 17 is connected to one side of the timing belt set 15. The second mounting part 18 is connected to the other side of the synchronous belt group 15. The first mounting part 17 is moved by the clamping cylinder 14, which in turn moves the synchronous belt group 15. Since the synchronous belts on the upper and lower sides of the synchronous belt group 15 move in opposite directions, the clamping cylinder 14 can drive the first mounting part 17 and the second mounting part 18 to move towards each other or away from each other. The guide member 16 is set on the wire path to guide the wire. An encoder 19 can also be installed on one of the clamping wheels of the clamping wheel group 12, and a wire-carrying motor 20 can be installed on one of the clamping wheels of the clamping wheel group 13. The wire-carrying motor 20 can be a servo motor, which can cooperate with the encoder to complete closed-loop control and control the conveying length. Since this closed-loop control is a conventional technical solution, it will not be described in detail.

[0025] In some embodiments, the device further includes a wire tooling assembly 21, which is disposed between the wire feeding mechanism 7 and the heat shrink tubing heating mechanism 5. The wire tooling assembly 21 has a cutting slit, and the cutting blade of the wire cutting mechanism 6 is located within the cutting slit. The wire tooling assembly 21 is provided with multiple types of guide sleeves 28. The wire tooling assembly 21 is used to guide the wire, and the multiple types of guide sleeves 28 are provided to adapt to various types of wires.

[0026] Specifically, in conjunction with the appendix Figure 6 and attached Figure 7As shown, the wire tooling assembly 21 includes a single-axis linear module 22, a mounting plate 23, a first wire guide gripper 24, a second wire guide gripper 25, a composite gripper 26, and an opening / closing cylinder 27. The single-axis linear module 22 is used to achieve linear drive in the linear direction. The mounting plate 23 is set at the drive end of the single-axis linear module 22. The first wire guide gripper 24, the second wire guide gripper 25, and the opening / closing cylinder 27 are all set on the mounting plate 23. There is a cutting slit between the first wire guide gripper 24 and the second wire guide gripper 25. The cutting blade of the wire cutting mechanism 6 can extend into the cutting slit to cut the wire. Multiple guide sleeves 28 are arranged side by side on the first wire guide gripper 24 along the driving direction of the single-axis linear module 22. Each guide sleeve 28 corresponds to a wire type, thus allowing the wire to be cut. The equipment is adaptable to the processing of various wires. The second wire guide gripper 25 is provided with wire-passing holes that correspond one-to-one with the guide sleeve 28. The composite gripper 26 is set on the opening and closing cylinder 27. The composite gripper 26 has wire-clamping grooves that correspond one-to-one with the wire-passing holes. The heating head of the heat shrink tubing heating mechanism 5 can extend to both sides of the composite gripper 26. The composite gripper 26 can clamp the wire under the drive of the opening and closing cylinder 27. When the wire is clamped by the composite gripper 26 and will not move, the heat shrink tubing heating mechanism 5 can accurately heat the wire with the heat shrink tubing, so that the heat shrink tubing can be tightly attached to the wire, completing the high-quality heat shrinking treatment. This effectively avoids problems such as uneven heat shrinking and heat shrink tubing offset caused by wire movement, greatly improving the stability of the entire processing flow and the quality of the finished product.

[0027] In some embodiments, the heat shrink tubing transfer mechanism 4 includes a flipping cylinder 29, a flipping frame 30, and heat shrink tubing clamping claws 31. The flipping frame 30 is provided on the rotating shaft of the flipping cylinder 29, and at least two heat shrink tubing clamping claws 31 are provided at both ends of the flipping frame 30.

[0028] Combined with appendix Figure 8 As shown, the tilting cylinder 29, as a key driving component of the heat shrink tubing transfer mechanism 4, can rotate at a preset angle and speed, thereby precisely driving the tilting frame 30 to tilt, ensuring that the heat shrink tubing clamping claws 31 can accurately transfer the heat shrink tubing to the designated position, providing reliable material conveying for subsequent tubing insertion and heat shrinking operations. At least two heat shrink tubing clamping claws 31 are provided at both ends of the tilting frame 30, ensuring that two heat shrink tubings are clamped simultaneously each time, corresponding to the two ends of the wire. The heat shrink tubing clamping claws 31 can be pneumatic clamps.

[0029] In some embodiments, the heat shrink tubing cutting mechanism 3 includes an upper cutting cylinder 32, an upper cutting blade 33, a lower cutting cylinder 34, and a lower cutting blade 35. The upper cutting blade 33 is provided at the driving end of the upper cutting cylinder 32, and the lower cutting blade 35 is provided at the driving end of the lower cutting cylinder 34. Both the upper cutting blade 33 and the lower cutting blade 35 are U-shaped and are staggered. A limiting space is formed between the upper cutting blade 33 and the lower cutting blade 35, and the heat shrink tubing passes through the limiting space.

[0030] Combined with appendix Figure 9 As shown, the heat shrink tubing cutting mechanism 3 includes two cutting components. Each cutting component includes an upper cutting cylinder 32, an upper cutting blade 33, a lower cutting cylinder 34, and a lower cutting blade 35. This cutting method ensures that the heat shrink tubing is cut accurately and neatly, effectively avoiding problems such as burrs and uneven cuts during the cutting process. This greatly improves the cutting quality and provides a good foundation for subsequent processes such as tubing insertion and heat shrinking. It ensures the smoothness and stability of the entire integrated machine's workflow, thereby improving the overall production efficiency and finished product quality.

[0031] In some embodiments, a heat shrink tubing guide assembly 36 is also included, which is disposed between the heat shrink tubing feeding mechanism 1 and the heat shrink tubing cutting mechanism 3. The heat shrink tubing guide assembly 36 includes a linear drive mechanism 37 and a guide fixture 38. The guide fixture 38 is disposed on the linear drive mechanism 37 and is provided with a plurality of guide holes 39 of various types arranged side by side along the driving direction of the linear drive mechanism 37. The guide fixture 38 is provided with a marking station 40 and a cutting station 41.

[0032] Combined with appendix Figure 1 and attached Figure 10 As shown, the heat shrink tubing guide assembly 36 guides the heat shrink tubing and ensures that it does not move arbitrarily during the cutting process. The linear drive mechanism 37 linearly drives the guide fixture 38 to move, allowing the guide fixture 38 to select the appropriate guide hole 39 to guide and position the heat shrink tubing according to different models. The marking station 40 is a slot opened in the guide fixture 38, which faces the heat shrink tubing marking mechanism 2 above, thus enabling marking. The cutting station 41 has two cutting components of the heat shrink tubing cutting mechanism 3 on each side, thereby enabling the cutting of the heat shrink tubing.

[0033] In some embodiments, the heat shrink tubing heating mechanism 5 includes an actuating cylinder 42 and a heating module 43. The heating module 43 is disposed at the driving end of the actuating cylinder 42, and the heating end of the heating module 43 is provided with a U-shaped groove 44, into which the heat shrink tubing can extend. The actuating cylinder 42 can drive the heating module 43 to reciprocate up and down. During the waiting stage for threading, the heating module 43 is located below the heating station. When the upper wire passes through the heat shrink tubing held by the heat shrink tubing clamping claw 31, the heat shrink tubing clamping claw 31 opens, and then the actuating cylinder 42 drives the heating module 43 to move upward, so that part of the heat shrink tubing is located in the U-shaped groove 44. At this time, the heating module 43 starts heating, which can heat the heat shrink tubing to the required temperature in a short time, making the heating more uniform.

[0034] In some embodiments, the heat shrink tubing marking mechanism 2 is a laser marking device. The laser marking device can be a cold ultraviolet laser, which will not damage the heat shrink tubing. The laser can be mounted on a lifting platform, and the transition plate between the lifting platform and the laser adopts an elongated hole mechanism, which allows for easy adjustment of the relative position of the laser's light emission position and the heat shrink tubing printing station.
