Description
Technical Field
[0001] This invention specifically relates to a fully automatic intelligent piercing, feeding, and terminal crimping machine, belonging to the field of wire harness processing technology. Background Technology
[0002] With the increasing advancement of automation technology, more and more industries are replacing manual labor with automation, and customers' requirements for wire harnesses are also getting higher and higher. Each wire in the same wire harness has different requirements. Currently, the existing piercing and terminal crimping equipment in the industry basically transports single wires or multiple wires at the same time. When processing wire harnesses, if the wire harness is not straight enough or there is a knot, it will seriously affect the wire feeding accuracy. Traditional wire feeding mechanisms have difficulty ensuring stable friction for accurate feeding when faced with wire harnesses with poor physical conditions (such as bending or knotting). Moreover, when multiple wire harnesses are transported independently at the same time, the abnormal state of one wire harness (such as being affected by other wire harnesses even when feeding stops) can easily interfere with the normal operation of other wire harnesses, thereby affecting the overall processing accuracy and efficiency.
[0003] Therefore, in order to address the shortcomings of existing technologies, a fully automatic intelligent piercing, wire feeding and terminal crimping machine is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide a fully automatic intelligent piercing, wire feeding, and terminal crimping machine to solve the problems mentioned in the background art.
[0005] This invention achieves the above objectives through the following technical solution: a fully automatic intelligent piercing, wire feeding, and terminal crimping machine, comprising a frame, characterized in that: The wire harness feeding and measuring mechanism includes an inlet straightening module disposed on the outer side, a wire harness clamping cylinder assembly disposed at the output end of the inlet straightening module, a wire control module disposed at the output end of the wire harness clamping cylinder assembly for controlling the wire harness length, and a guide conveying module for driving the wire harness feeding and measuring mechanism. The wire control module includes a first unpowered wheel assembly and a first wire control lifting cylinder assembly that drives the first unpowered wheel assembly, a second unpowered wheel assembly, a second wire control lifting cylinder assembly that drives the second unpowered wheel assembly, and a first wire control gear assembly meshing with the second unpowered wheel assembly. The wire control module is controlled by a motor to achieve precise feeding and fixed-length cutting linkage. A terminal mechanism for processing wire harnesses includes a terminal frame, a terminal motor mounted on the terminal frame, a terminal feeding module, and a terminal crimping module, wherein the terminal crimping module includes a terminal feeding track.
[0006] Furthermore, the wire harness feeding and length measuring mechanism also includes a synchronous belt conveyor structure, which includes a first drive shaft, a first passive shaft, a second drive shaft, a second passive shaft, and a synchronous belt wound around and connected to the drive shaft and the passive shaft. The first drive shaft and the second drive shaft drive the first wire control gear set to rotate, and the first passive shaft drives the first unpowered wheel set to rotate.
[0007] Furthermore, it also includes a piercing mechanism for piercing the wire harness after it has been fed into the wire harness. The piercing mechanism includes a piercing blade, a terminal rail, and a terminal fixing module disposed below the terminal rail.
[0008] Furthermore, it also includes a peeling mechanism, which comprises an upper cutting module, a lower cutting module, and a cutting motor that drives the upper and lower cutting modules to move.
[0009] Furthermore, it also includes a terminal feeding mechanism, which includes a terminal feeding track, a placement module, a corner cutting module, a first corner cutting moving module, and a second corner cutting moving module.
[0010] Furthermore, it also includes a wire harness feeding mechanism, which is disposed on one side of the stripping mechanism. The wire harness feeding mechanism further includes a moving module, a wire clamping module, and a wire straightening module.
[0011] Furthermore, the wire harness feeding and measuring mechanism also includes a wire straightening module, which is located at the output end of the wire harness feeding and measuring mechanism and is used to straighten wire harnesses with different feeding accuracies and send them to the wire harness feeding mechanism.
[0012] Furthermore, the stripping mechanism also includes a waste collection module for collecting wire harness waste.
[0013] Furthermore, the puncture mechanism also includes a detection component.
[0014] Furthermore, the terminal feeding mechanism also includes a feeding assembly.

At the same time, in conjunction with cutting and stripping actions, visual inspection and continuity detection, a closed loop of "execution-inspection-sorting" is formed, which can detect defects such as poor corner cutting, poor puncture, and poor continuity in real time. Wire harness processing and terminal processing can be carried out synchronously and in parallel, shortening the overall cycle time and greatly improving production efficiency.

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-8 As shown, Figures 1-8 The illustration shows the fully automatic intelligent piercing, wire feeding, and terminal crimping machine of the present invention.
[0019] A fully automatic intelligent wire-piercing and terminal-clamping integrated machine, comprising a frame 1, characterized in that: The wire harness feeding and measuring mechanism 2 includes an inlet straightening module on the outside, a wire harness clamping cylinder assembly 2.2 on the output end of the inlet straightening module, a wire control module 2.3 on the output end of the wire harness clamping cylinder assembly 2.2 for controlling the length of the wire harness, and a guide conveying module 2.4 for driving the wire harness feeding and measuring mechanism 2. The wire control module 2.3 includes a first unpowered wheel assembly 2.31 and a first wire control lifting cylinder assembly 2.32 that drives the first unpowered wheel assembly 2.31, a second unpowered wheel assembly 2.33, a second wire control lifting cylinder assembly 2.34 that drives the second unpowered wheel assembly 2.33, and a first wire control gear assembly 2.35 that meshes with the second unpowered wheel assembly 2.33. The wire control module 2.3 is controlled by a motor to achieve precise feeding and fixed-length cutting linkage. The terminal mechanism 3 is used to process wire harnesses and includes a terminal frame 3.1, a terminal motor 3.2 mounted on the terminal frame 3.1, a terminal feeding module 3.3, and a terminal crimping module 3.4. The terminal crimping module 3.4 includes a terminal feeding track 3.41.
[0020] Among them, the terminal mechanism is the final operating mechanism after the wire harness has been stripped and cut, and is used to perform terminal crimping on the wire harness.
[0021] The terminal feeding track 3.41 transports the wire harness that needs to be terminal-crimped to the terminal crimping module 3.4 of the terminal mechanism 3, while the terminal feeding module 3.3 transports the terminal to the terminal crimping module 3.4.
[0022] The present invention includes, but is not limited to, two terminal mechanisms to enable high-speed wire harness terminal crimping.
[0023] Furthermore, the wire harness feeding and length measuring mechanism 2 also includes a synchronous belt transmission structure, which includes a first drive shaft 2.5, a first driven shaft 2.7, a second drive shaft 2.6, a second driven shaft 2.8, and a synchronous belt 2.9 connected to the drive shaft and the driven shaft. The first drive shaft 2.5 and the second drive shaft 2.6 drive the first wire control gear set 2.35 to rotate, and the first driven shaft 2.7 drives the first unpowered wheel set 2.31 to rotate.
[0024] Among them, the guide conveyor module 2.4 is adopted, which realizes independent control of each wire harness through the meshing gear mechanism.
[0025] The outer wire straightening module (not shown) is used to straighten the pre-processed wire harness.
[0026] The unpowered wheel assembly consists of multiple unpowered wheels, and the wire lifting cylinder assembly consists of multiple wire lifting cylinders. Each unpowered wheel is equipped with a wire lifting cylinder. When the wire lifting cylinder is activated, the unpowered wheel rotates around the passive shaft, independently controlling the meshing gap between the unpowered wheel and the driving wheel, thereby controlling the conveying friction between the two wheels.
[0027] The motor drives the active wheel and the passive wheel to rotate simultaneously, ensuring that each wheel is under force. It is also equipped with a wire harness clamping cylinder assembly. When the wire lifting cylinder is lifted, the active wheel and the passive wheel separate and stop feeding wire, and the corresponding wire harness clamping cylinder assembly will clamp the wire harness.
[0028] The guide conveying module and the wire control module work together to achieve independent and precise control of each wire harness. When the wire harness needs to be conveyed, the wire control lifting cylinder group descends, causing the unpowered wheel and the driving wheel to clamp the wire harness and convey it through friction. When the wire harness does not need to be conveyed or needs to be stopped, the wire control lifting cylinder group rises, the two wheels separate, the wire harness stops conveying, and it does not affect the normal conveying of other wire harnesses. By adjusting the airflow of the cylinder, the friction between the wire harness and the wheel can be precisely controlled to ensure the wire feeding accuracy and avoid damaging the wire harness.
[0029] The synchronous belt conveyor structure ensures that the driving wheel and the driven wheel rotate synchronously and stably, so that each wire harness can be evenly stressed during the conveying process, which further improves the accuracy and stability of wire delivery and effectively copes with situations where the wire harness is not straight or bent.
[0030] Among them, the wire harness clamping cylinder assembly serves as an auxiliary mechanism. It plays a role when the control wire lifting cylinder group is raised and the wire harness stops feeding. In order to prevent the stopped wire harness from being affected by other wire harnesses or from creating new knots, the wire harness clamping cylinder assembly of the wire harness feeding and measuring mechanism will clamp the wire harness in time. This ensures that even if the wire harness is not straight or has a tendency to knot, it can be effectively fixed when feeding stops, preventing it from affecting the normal operation of other wire harnesses. This fundamentally solves the problem of the impact of the wire harness not being straight or knots on the feeding accuracy, and ensures the stability and high precision of feeding multiple wire harnesses simultaneously and independently.
[0031] Furthermore, it also includes a piercing mechanism 4, which is used to pierce the wire harness after it has been fed. The piercing mechanism 4 includes a piercing knife 4.1, a terminal rail 4.2, and a terminal fixing module 4.3 disposed below the terminal rail 4.2.
[0032] Furthermore, it also includes a peeling mechanism 5, which includes an upper cutting module, a lower cutting module, and a cutting motor 5.5 that drives the upper and lower cutting modules to move.
[0033] The upper cutting module includes an upper cutting blade 5.1 and an upper peeling blade 5.3, while the lower cutting module includes a lower cutting blade 5.2 and a lower peeling blade 5.4.
[0034] Among them, the upper cutter 5.1 and the lower cutter 5.2 utilize the principle of scissors, with the entire blade moving in parallel. After cutting the wire, each wire can be neatly arranged, preparing for piercing the terminal block.
[0035] Among them, the upper stripping knife 5.3 and the lower stripping knife 5.4 adopt beveled toothed blades, which can achieve complete stripping without cutting the wires inside the wire harness, providing qualified wire harness ends for subsequent piercing and terminal crimping processes.
[0036] Furthermore, it also includes a terminal feeding mechanism 6, which includes a terminal feeding track 6.1, a placement module 6.2, a corner cutting module 6.3, a first corner cutting moving module 6.4, and a second corner cutting moving module 6.5.
[0037] Furthermore, it also includes a wire harness feeding mechanism 7, which is located on one side of the stripping mechanism 5. The wire harness feeding mechanism 7 also includes a moving module 7.1, a wire clamping module 7.2, and a wire straightening module 7.3.
[0038] Furthermore, the wire harness feeding and measuring mechanism 2 also includes a wire straightening module 2.10, which is set at the output end of the wire harness feeding and measuring mechanism 2 and is used to straighten wire harnesses with different feeding accuracies and send them to the wire harness feeding mechanism 7.
[0039] Furthermore, the stripping mechanism 5 also includes a waste collection module 5.6 for collecting wire harness waste.
[0040] Furthermore, the puncture mechanism 4 also includes a detection component 4.4.
[0041] The detection component 4.4 also includes a visual detection component 4.41 and a probe detection conduction component 4.42.
[0042] The puncture mechanism 4 also includes a material distribution component 4.5.
[0043] Among them, the piercing knife 4.1 in the piercing mechanism 4 pierces the outer layer of the wire harness under the drive of a cylinder or motor.
[0044] Among them, the visual inspection component 4.41 can detect punctured defective products and can detect the pass rate of punctures and the pass rate of the front chamfer. The probe detection continuity component 4.42 also uses pneumatic principle to send the detection probe to the corresponding position of the terminal continuity to complete the continuity detection. It transforms manual visual inspection into automated machine vision inspection, which greatly improves the accuracy, consistency and efficiency of inspection and reduces the missed detection rate.
[0045] Among them, the detection component 4.4 separates the defective punctured products, and the sorting component 4.5 classifies the defective punctured products and puts them aside separately, thereby improving the efficiency of the equipment in producing good products.
[0046] Furthermore, the terminal feeding mechanism 6 also includes a feeding assembly 6.7.
[0047] The terminal feeding mechanism 6 is used to separate the terminal from the fixture and transport it to the position where it needs to be punctured.
[0048] Among them, a pressure plate 6.8 is installed above the feeding component.
[0049] The terminal is delivered from the placement module 6.2 to the operating area of the transition component 6.9 by air blowing. Then, the cylinder of the transition component 6.9 moves the terminal to the first corner cutting moving module and the second corner cutting module. The corner cutting module cuts off the unnecessary terminal transition angle. After the corner is cut, the cylinder of the transition component 6.9 moves the terminal to the transition component 6.9. The transition component 6.9 then moves the terminal to the terminal track 4.2.
[0050] The working principle of the fully automatic intelligent piercing, wire feeding, and terminal crimping machine in this invention is as follows: The wire harness transportation and terminal crimping are carried out simultaneously, achieving high-speed and high-quality collaborative work.
[0051] The wire harness to be transported is placed in the wire harness feeding and length measuring mechanism. First, the wire harness is straightened by the wire straightening module, and then the wire harness clamping cylinder assembly clamps and fixes the wires in place. This position is designed with a pneumatic device for individual clamping of each wire, ensuring the movement and stopping of each wire. Then, the wire control module 2.3 clamps the wires using upper and lower rollers, allowing the wires to be transported through the friction of the two rollers. The wire wheels are fed by two sets of mutually acting clamping roller assemblies, both upper and lower rollers being actively driven. During the wire harness transport process, the combined movement of the upper and lower rollers is controlled by a cylinder to control the transport length of the wire harness. Each wire is controlled by an independent cylinder, thus achieving independent control of each wire. The wire harness is transported to the stripping mechanism. Only the wire harness used for piercing does not need to be stripped; the cutting action is sufficient. The wire harness that needs to be terminalized must be stripped at the same time as being cut. The cutting and stripping action is completed by a motor. After the wire harness to be pierced is cut, it is clamped by the wire clamping module of the wire harness feeding mechanism and sent to the piercing mechanism to complete the piercing action. After the wire harness that needs to be terminalized is cut and stripped, it is sent to the terminal crimping machine. The terminal winding area motor in the terminal winding area sends the terminal to the terminal mechanism to complete the terminal crimping action. Simultaneously, the terminal is delivered from the placement module to the terminal feeding track via air blowing. Then, the terminal is sent to the corner cutting module by the action of the cylinder. The corner cutting module cuts off the unnecessary terminal transition angle. After the corner is cut, the cylinder sends the terminal to the transition component again, and then sends the terminal track to the terminal feeding track position. The two tracks merge and transport the terminal to the terminal track. This track can complete piercing, CCD detection, continuity detection, NG material classification, etc., to complete the continuity work of piercing the wire harness and the terminal.
[0052] The beneficial effects of this invention are: This invention uses an independent cylinder to clamp each wire harness, a non-powered wheel assembly, and a wire control gear set to drive it. This achieves length control and transportation of a single wire, avoiding mutual interference when multiple wires are processed simultaneously. It ensures high precision in wire cutting length and wire feeding position. In conjunction with cutting and stripping actions, visual inspection, and continuity detection, a closed loop of "execution-inspection-sorting" is formed. This can detect defects such as poor corner cutting, puncture, and poor continuity in real time. Wire harness processing and terminal processing can be carried out simultaneously and in parallel, shortening the overall cycle time and significantly improving production efficiency.
