Description

Technical Field

[0001] The present invention relates to the technical field of terminal assembly equipment, and in particular to a single-head crimping terminal cable assembly machine and a processing technology thereof. Background Art

[0002] At present, in the terminal assembly process, it is necessary to prepare the terminal to be assembled and the cable to be assembled. The terminal has a slot for inserting the cable, and a buckle is also movably provided on the terminal. After the cable is inserted into the slot, the buckle is engaged with the slot of the terminal through the buckle, thereby fixing the cable in the terminal and realizing the assembly of the terminal. In the prior art, the cable is usually inserted into the slot manually, which has low work efficiency. Especially when the terminal slot and the cable diameter are small, the assembly difficulty of the workers is greatly increased, and the labor intensity is high.

[0003] Another terminal assembly device in the prior art uses a mobile module to insert a prefabricated cable into the slot of the terminal, and presses the buckle through a pressure head, or pushes the buckle to achieve assembly between the buckle and the terminal. However, for some terminals, the buckle does not have a single assembly direction. Pressing or pushing alone cannot ensure that the buckle is assembled in place on the terminal. There is a phenomenon of a virtual assembly state, which makes it difficult to imitate the assembly action of the hand. If the action mechanisms are set separately, it is difficult to set multiple action mechanisms for a small terminal assembly space, and multiple action mechanisms need to act and return separately, affecting the assembly efficiency.

[0026] The present invention also provides a processing technology for a single-head crimping terminal cable assembly machine, comprising:

[0027] Cable processing steps:

[0028] A1 Cable straightening and feeding: In the third transfer track, place the cable aligned with the first guide port. The cable enters the feeding track under the force of the rear-end conveyor. The cable is guided by the first roller group and the second roller group, and is stretched and straightened after being subjected to the forces in the perpendicular directions.

[0029] The cable passes through the second guide port at the front end and enters the cable inlet pipe, and is pressed by the active rollers of the third roller group toward the cable stripping and cutting station until the front end of the cable enters the cable stripping and cutting station;

[0030] A2 cable front-end stripping, the cable stripping station includes multiple cable stripping modules, and cuts the front end of the cable, strips the cable jacket and cable core to expose the core and conductors at the front end of the cable;

[0031] A3 Cable front-end processing: On the fourth transfer track, the second incoming cable module is transferred through the cable processing module, which includes a wire twisting claw, a rosin dipping bin, and a tinning bin.

[0032] A4 cable fixed-length stripping: In the second transfer track, a cable clamping tool is installed on it. The first and second cable entry modules further feed the cable until the cable passes through the cable clamping tool and reaches the desired length. At this time, the cable clamping tool grabs the front end of the cable, and the rear end of the cable is placed in the cable stripping station, where the rear end of the cable is cut and the cable jacket and cable core are stripped;

[0033] Cable assembly process:

[0034] C1 terminal loading: The terminal unit is loaded through the vibration plate and enters the terminal positioning tooling. The terminal unit is limited vertically, laterally, and front and rear ends in the terminal positioning tooling, and the opening of the terminal unit is facing the second transfer track;

[0035] C2 cable insertion, including a fifth transfer track covering the first transfer track and the second transfer track, the fifth transfer track is provided with a cable plugging tool, the cable plugging tool clamps the inner core and wire at the rear end of the cable and transfers the cable until it is inserted into the terminal unit;

[0036] C2.1 For Class I terminal assembly, the contouring module drives the fixed frame and contouring member downward until the contouring member abuts the upper end of the main body. The contouring module drives the contouring member to roll against the end face of the main body while maintaining abutment. The contouring member forces the assembly portion toward the opening and applies a force at the front end of the assembly portion to close the assembly portion within the opening.

[0037] C2.2 For Class II terminal assembly, the profiling module drives the fixed frame and profiling member downward until the profiling member abuts the upper end of the assembly portion. The profiling member is abutted by the assembly portion and received within the fixed frame, and a pushing portion facing the assembly portion is formed between the fixed frame and the profiling member. The profiling module drives the fixed frame and profiling member to translate, and the pushing portion pushes the assembly portion to the end of the assembly section. At this point, a vertical assembly gap is formed between the assembly portion and the assembly section. The profiling member vertically presses the assembly portion, forcing the assembly portion to snap into place, so that the assembly portion presses against the cables within the assembly section.

[0038] C3 finished product unloading.

[0039] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0040] By limiting the terminal unit on the terminal positioning tooling and limiting the degree of freedom of the terminal unit, after the cable is inserted into the opening, the profiling action module drives the fixed frame and the profiling member downward, and the profiling member abuts against the terminal unit under the action of the elastic member. As the profiling member and the fixed frame move relative to the terminal unit, the profiling member floats with the outline of the terminal unit and maintains a downward force to ensure the stability of the terminal part's snap-on action. When the profiling member floats with the outline of the terminal unit and is retracted into the fixed frame, the fixed frame is able to push the assembly part to drive the assembly part to tend to engage with the main body. In this process, the assembly part is subjected to a constant horizontal force and a vertical force adjusted in real time, thereby simulating hand movements. At the same time, during the movement of the profiling action module and when leaving the terminal unit, the profiling member always acts on the assembly part. If the assembly part is incompletely assembled, the assembly part is further flattened on the main body under the action of the fixed frame, thereby achieving stable assembly of the terminal unit and the assembly part.

[0085] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0086] It should be understood that although terms such as upper, middle, lower, top, end, etc. appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for ease of understanding, and are not used to define any direction or order limitation.

[0087] like Figure 1-2 As shown, a single-head crimping terminal cable assembly machine includes:

[0088] The terminal transfer module includes a first transfer track 2 arranged transversely, and a plurality of terminal positioning tools 1 that translate relative to the first transfer track 2. The plurality of terminal positioning tools 1 are used to carry and constrain the terminal units 5 therein;

[0089] The terminal loading module includes a plurality of longitudinally arranged vibration disks 14, a terminal loading position provided on the output end of the vibration disk 14, and a terminal clamping module 13 provided above the terminal loading position. The terminal clamping module 13 is configured to move longitudinally and is used to clamp the terminal unit 5 to the terminal positioning tool 1. Different types of terminal units 5 are stored in the plurality of vibration disks 14 respectively.

[0090] The cable transfer module includes a second transfer track 3 arranged horizontally, and a cable clamping tool 4 and a cable plugging tool that move horizontally about the second transfer track 3.

[0091] The cable clamping tool 4 is used to clamp the cable and is configured to move toward the terminal positioning tool 1. The cable plugging tool is located above the second transfer track 3 and is connected to the cable clamping tool 4, thereby grabbing the cable on the cable clamping tool 4. The first transfer track 2 and the second transfer track 3 at least partially overlap, thereby connecting the terminal positioning tool 1, the cable plugging tool and the cable clamping tool 4. The cable plugging tool is configured to move in the cable assembly direction, thereby plugging the cable into the terminal unit 5.

[0092] The cable transfer module also includes a third transfer track 7 arranged longitudinally. The third transfer track 7 is connected to the initial end of the second transfer track 3. The third transfer track 7 is used to receive the cables and guide the cables into the cable clamping tooling 4.

[0093] The terminal unit 5 includes a main body 5.2 having an inner cavity, and an assembly portion 5.1 movably disposed on the main body 5.2. An opening 5.3 for inserting a cable is provided at the front end of the main body 5.2. The assembly portion 5.1 is fixedly engaged with the opening 5.3 and restricts insertion of the cable into the main body 5.2. The assembly portion 5.1 has assembly movements in different directions, which are specifically implemented by an assembly movement tool 6.

[0094] like Figure 4 As shown, the assembly action tooling 6 is arranged above the terminal positioning tooling 1, and includes a profiling action module 6.1, a fixed frame 6.2 provided on the action end of the profiling action module 6.1, a profiling member 6.3 floatingly arranged in the fixed frame 6.2, and an elastic member 6.4 abutting between the profiling member 6.3 and the fixed frame 6.2. The elastic member 6.4 drives the profiling member 6.3 to extend out of the fixed frame 6.2, and the profiling action module 6.1 is used to drive the fixed frame 6.2 and the profiling member 6.3 to perform translational or vertical movements.

[0095] The contour action module 6.1 drives the fixed frame 6.2 and / or the contour member 6.3 to move in the assembly direction of the terminal unit 5, the contour member 6.3 is pressed against the assembly portion 5.1, and presses the assembly portion 5.1 to engage on the opening portion 5.3, and the elastic member 6.4 exerts a force on the contour member 6.3 to keep it on the assembly portion 5.1, so that the contour member floats relative to the contour of the assembly portion 5.1.

[0096] In order to improve the alignment of the contoured member 6.3 in the fixed frame 6.2, the fixed frame 6.2 is provided with a vertical guide groove 6.5, and the contoured member 6.3 is provided with a guide rod inserted into the guide groove 6.5, thereby limiting the vertical sliding of the contoured member 6.3 about the guide groove 6.5.

[0097] By limiting the terminal unit 5 on the terminal positioning tool 1 and limiting the degree of freedom of the terminal unit 5, after the cable is inserted into the opening 5.3, the profiling action module 6.1 drives the fixed frame 6.2 and the profiling member 6.3 downward, and the profiling member 6.3 abuts against the terminal unit 5 under the action of the elastic member 6.4. As the profiling member 6.3 and the fixed frame 6.2 move relative to the terminal unit 5, the profiling member 6.3 floats with the outline of the terminal unit 5 and maintains a downward force to ensure the stability of the terminal part buckling action. When the profiling member 6.3 floats with the outline of the terminal unit 5 and is collected in the fixed frame 6.2, , the fixing frame 6.2 is able to push the assembly part 5.1 to drive the assembly part 5.1 to tend to engage with the main body 5.2. During this process, the assembly part 5.1 is subjected to a constant horizontal force and a vertical force adjusted in real time, thereby simulating hand movements. At the same time, during the movement of the profiling action module 6.1 and when it leaves the terminal unit 5, the profiling member 6.3 always acts on the assembly part 5.1. If the assembly part 5.1 is incompletely assembled, the assembly part 5.1 will be further flattened on the main body 5.2 under the action of the fixing frame 6.2, thereby achieving stable assembly of the terminal unit 5 and the assembly part 5.1.

[0098] It should be pointed out that there are movable modules connected between the above-mentioned first transfer track 2 and the terminal positioning tooling 1, the terminal clamping module 13, the second transfer track 3 and the cable clamping tooling 4, the cable plug-in tooling, and the contour action module 6.1, thereby allowing the driving end of the above-mentioned module to perform three-axis movement. For the clamping action, it is preferably achieved by a pneumatic finger cylinder.

[0099] like Figure 8 As shown in FIG. 5 , as an embodiment of assembling a terminal unit 5 with a cable, the terminal unit 5 includes a terminal 5.4. A hinge portion 5.41 is provided between the assembly portion 5.1 and the upper end of the main body 5.2. The hinge portion 5.41 is a deformable arc-shaped rib. A buckle point 5.42 is provided on both sides of the assembly portion 5.1. A buckle groove 5.43 is provided on both sides of the opening portion 5.3. The assembly portion 5.1 is buckled into the opening portion 5.3 by rotation. At this time, the buckle point 5.42 cooperates with the buckle groove 5.43 to constrain the cable.

[0100] The contoured member 6.3 is in the form of a roller, specifically arranged on both sides of the end surface of the main body 5.2, and passes through the hinge portion 5.41 on the main body 5.2 along the assembly direction.

[0101] like Figures 11 to 13As shown, during the assembly process, the profiling action module 6.1 drives the fixed frame 6.2 and the profiling member 6.3 to move along the length direction of the main body 5.2. The profiling member 6.3 rolls on the upper end of the main body 5.2 and gradually presses against the hinge portion 5.41 and the assembly portion 5.1, thereby forcing the assembly portion 5.1 to rotate to the opening portion 5.3. As the profiling member 6.3 moves, the profiling member 6.3 is contracted by the reaction force of the hinge portion 5.41 and the contour of the assembly portion 5.1.

[0102] like Figure 12 As shown, when the assembly portion 5.1 rotates to the point where the contoured member 6.3 is located above the hinge portion 5.41 and the first-type buckle point 5.42 and the first-type buckle groove 5.43 tend to match, the force of the elastic member 6.4 reaches a maximum value, overcoming the abutment force between the first-type buckle point 5.42 and the first-type buckle groove 5.43, forcing the first-type buckle point 5.42 to buckle into the first-type buckle groove 5.43;

[0103] like Figure 13 As shown, as the contour member 6.3 continues to move, the contour member 6.3 presses against the front end of the assembly portion 5.1. At this time, the roller-shaped contour member 6.3 exerts a backward force on the assembly portion 5.1 placed in the opening portion 5.3 during the rotation process, so as to ensure that the assembly portion 5.1 is completely buckled into the opening portion 5.3. During the assembly process, the contour member 6.3, under the action of the elastic member 6.4, always exerts a downward force on the main body 5.2, the assembly portion 5.1 and its hinge portion 5.41, thereby ensuring the stability of the assembly process.

[0104] When the profiling member 6.3 is pressed against the main body 5.2, the elastic member 6.4 has a compression stroke D1. When the profiling member 6.3 is pressed against the hinge portion 5.41, the elastic member 6.4 has a compression stroke D2. When the profiling member 6.3 is pressed against the front end of the assembly portion 5.1, the elastic member 6.4 has a compression stroke D3. Among them, D2 is greater than D1, and D1 is greater than D3. Figures 11 to 13 The figure only shows the degree of compression of the elastic member 6.4.

[0105] Specifically, the roller is arranged corresponding to the hinge part 5.41 so that the roller passes through and presses the hinge part 5.41 during movement, and a rib is provided on the outer side of the roller, which matches the outer boundary of the main body 5.2 to improve the matching reliability of the profiling member 6.3 and the first type terminal 5.4.

[0106] like Figure 9 and Figure 10 As shown in FIG. 5 , as another embodiment of the assembly of the terminal unit 5 and the cable, the terminal unit 5 includes a second-class terminal 5.5, a main body 5.2 includes an assembly section 5.51, and an assembly portion 5.1 is slidably arranged on the assembly section 5.51;

[0107] The assembly section 5.51 is provided with a first latching point 5.52 and a second latching point 5.53, and the assembly portion 5.1 is provided with a second type of latching groove 5.54. The assembly section 5.51 is also provided with an inclined first groove 5.59, and the assembly portion 5.1 is provided with an inclined block 5.57 capable of being engaged within the first groove 5.59. The opening portion 5.3 is specifically formed at the front end of the assembly section 5.51 and forms a front opening 5.56. The opening portion 5.3 passes through the upper end surface of the assembly section 5.51 to form an upper opening 5.55. The assembly portion 5.1 is provided with a pressing block 5.58 capable of being engaged therein.

[0108] With the above structure, the assembly portion 5.1 has a first position tilted on the assembly section 5.51, a second position tilted against the end of the assembly section 5.51, and a third position flush with the assembly section 5.51.

[0109] It should be noted that the upper front end of the assembly section 5.51 is also provided with a ramp, and a clearance opening for the ramp to pass through is provided on one side of the fixed frame 6.2. The bottom of the contoured member 6.3 has a flat surface that matches the Class II terminal 5.5. The ramp is used to maintain the inclined posture of the assembly portion 5.1 in the first position.

[0110] like Figure 14 As shown, in the first position, the inclined block 5.57 abuts within the first groove 5.59 and abuts against the upper part of the second clamping point 5.53, the first clamping point 5.52 cooperates with the second clamping groove 5.54, and the pressing block 5.58 is partially placed in the upper opening 5.55, the upper opening 5.55 is partially exposed, and the assembly portion 5.1 is attached to the inclined platform;

[0111] The profiling action module 6.1 is actuated, driving the fixed frame 6.2 to be located at the front end of the assembly portion 5.1. The profiling member 6.3 is pressed against the inclined assembly portion 5.1, and the profiling member 6.3 is pressed by the assembly portion 5.1 and received in the fixed frame 6.2, so that an L-shaped pressing area is formed between the fixed frame 6.2 and the profiling member 6.3. The depth of the pushing area changes with the vertical floating of the profiling member 6.3.

[0112] Furthermore, the profiling action module 6.1 drives the fixing frame 6.2 to move horizontally, forcing the pushing portion to apply a horizontal force to the assembly portion 5.1. At the same time, the profiling member 6.3 applies a vertical force to the assembly portion 5.1. When the horizontal force overcomes the abutment force between the first clamping point 5.52 and the second clamping groove, the assembly portion 5.1 is pushed and abuts against the end of the assembly portion 5.1, so that the assembly portion 5.1 reaches the second position, wherein the second clamping point 5.53 is located below the first clamping point 5.52. The first clamping point 5.52 is specifically arranged on the inclined platform. Under the action of the first groove 5.59 and the inclined block 5.57, the assembly portion 5.1 moves downward by a stroke.

[0113] like Figure 15and Figure 16 As shown, in the second position, the assembly portion 5.1 is still fixed in an inclined posture, and the rear end of the assembly portion 5.1 abuts against the bottom surface of the assembly section 5.51, the front end of the assembly portion 5.1 is mounted on the upper part of the second clamping point 5.53, and the pressing block 5.58 is placed in the upper opening 5.55 in an inclined posture, closing the upper opening 5.55 and initially positioning it with the cable in the assembly section 5.51. At this time, the inclined block 5.57 is disengaged from the first groove 5.59 and allowed to fit downwardly on the bottom surface of the assembly section 5.51, that is, the rear end of the assembly portion 5.1 is fixed, and the front end of the assembly portion 5.1 needs to be fastened to the assembly section 5.51 in a rotational manner;

[0114] At this time, under the action of the elastic member 6.4, the contoured member 6.3 applies a downward force to the front end of the assembly portion 5.1 and overcomes the abutment force between the second clamping point 5.53 and the second type of clamping slot 5.54, so that the front end of the assembly portion 5.1 moves downward and abuts inside the assembly portion 5.1, and the second clamping point 5.53 is able to be buckled with the second type of clamping slot 5.54. At this time, the assembly portion 5.1 is flush with the assembly section 5.51 and is horizontally limited to the rear end of the first clamping point 5.52, and the rear end of the assembly portion 5.1 is abutted against the end of the assembly section 5.51. The pressing block 5.58 is completely placed in the upper opening 5.55, pressing the cable in the assembly section 5.51, thereby fixing the cable and the assembly portion 5.1 in the main body 5.2.

[0115] In the process of moving from the first position to the second position and from the second position to the third position, the contoured member 6.3 always applies a vertical downward force to the assembly portion 5.1 to ensure that the assembly portion 5.1 is installed in place.

[0116] like Figure 6 As shown, as a further embodiment of the terminal positioning tool 1, the terminal positioning tool 1 includes:

[0117] A tooling plate 1.1 is provided with a cavity matching the contour of the terminal unit 5, a first limiting rib 1.2 is provided at the end of the cavity, the first limiting rib 1.2 abuts against the terminal unit 5, and an opening 5.3 is exposed at the first limiting rib 1.2;

[0119] The limiting rod 1.5 is passed through one side of the tooling plate 1.1 corresponding to the terminal unit 5. The limiting rod 1.5 is against the terminal unit 5 and limits the terminal unit 5 to the current position. The limiting rod 1.5 is driven by a cylinder to extend into or out of the cavity.

[0120] Through the above improvements, the terminal unit 5 is subjected to circumferential limitation and upper and lower side limitation in the terminal positioning tool 1 to ensure the position stability during the assembly process of the terminal unit 5.

[0121] like Figure 7 As shown, as a variation of the terminal positioning tool 1, it also includes a second limiting cylinder 1.6, which is arranged opposite to the first limiting cylinder 1.3, and the second limiting cylinder 1.6 specifically refers to a finger cylinder, and the second limiting cylinder 1.6 forms a first limiting edge 1.2 at the front end of the tooling plate 1.1.

A movably arranged clamping jaw group 13.1 is provided above the first transfer track 2, and an unloading bin 12 is provided on the side away from the first transfer track 2. A clamping groove for the clamping jaw group 13.1 is provided on the tooling plate 1.1. The clamping jaw group 13.1 enters the tooling plate 1.1 through the clamping groove and clamps the assembled terminal unit 5, and then places the terminal unit 5 in the unloading bin 12.

[0123] As an option, the lower material bin 12 is divided into a finished product area 12 . 1 and an unqualified area 12 . 2 , specifically by partitions formed in the lower material bin 12 .

[0124] like Figure 3 As shown, as an implementation scheme of the terminal feeding module, the terminal clamping module 13 includes a clamping claw group 13.1 that is longitudinally movable, and the terminal feeding position includes a terminal frame 13.2 connected to the vibration disk 14. A loading cylinder 13.3 is provided at the bottom of the terminal frame 13.2, and the action end of the loading cylinder 13.3 is passed through the terminal frame 13.2, and the action end of the loading cylinder 13.3 is provided with a loading trough 13.4 that matches the contour of the terminal unit 5. The loading trough 13.4 is arranged opposite to the output port of the vibration disk 14. When the terminal unit 5 enters the loading trough 13.4, the loading cylinder 13.3 pushes the terminal unit 5 out of the terminal frame 13.2, and the terminal clamping module 13 is able to clamp the terminal unit 5 and transport the terminal unit 5 to the terminal positioning tooling 1.

[0125] from Figure 1 As can be seen in the figure, as a further embodiment of the cable transfer module, the cable transfer module includes a third transfer track 7, at least one incoming line module receiving the third transfer track 7, and a plurality of cable stripping modules 15 provided on the third transfer track 7.

[0126] The cable travels in the third transfer track 7 through the incoming cable module and is processed by the cable stripping module 15 . Then, the cable holding fixture 4 on the second transfer track 3 moves and receives the cable.

[0127] The cable stripping module 15 is used to cut and strip the front and rear ends of the cable to expose the connection terminals of the cable.

[0128] Among them, there are two incoming line modules, specifically including a first incoming line module 8 and a second incoming line module 9. The first incoming line module 8 stretches and straightens the cable in a passive manner, and the second incoming line module 9 stretches and straightens the cable in an active manner to ensure cable alignment.

[0129] Reference Figure 17 Specifically, the first incoming line module 8 includes:

[0130] The cable feed track 8.1 comprises a plurality of first roller groups 8.2 and second roller groups 8.3 arranged in sequence on the cable feed track 8.1, and first guide openings 8.4 and second guide openings 8.5 arranged at both ends of the cable feed track 8.1. The first guide openings 8.4 and second guide openings 8.5 are provided with arc openings set in the cable feed direction, and the first roller units 8.7 of the first roller groups 8.2 and second roller groups 8.3 are provided with closing openings to allow the cable to pass through, and the first roller units 8.7 are staggeredly arranged on both sides of the cable.

[0131] Among them, the first roller group 8.2 and the second roller group 8.3 are staggered with respect to the feed direction, and the rotation axes of the first roller group 8.2 and the second roller group 8.3 are perpendicular to each other. Preferably, the rotation axis of the first roller group 8.2 is vertically arranged, and the rotation axis of the second roller group 8.3 is horizontally arranged.

[0132] Specifically, a clamping module 8.6 is provided on the first roller group 8.2 and / or the second roller group 8.3, and the clamping module 8.6 applies a force toward the cable, wherein the clamping module 8.6 includes a clamping plate 8.61 and a clamping toggle clamp 8.62. The first roller units 8.7 on one side are arranged at intervals on the clamping plate 8.61, and the clamping toggle clamp 8.62 drives the clamping plate 8.61 away from or close to the first roller unit 8.7 on the other side, thereby releasing or straightening the cable.

[0133] Alternatively, the clamping toggle clamp 8.62 may be replaced by other stroke-controllable driving members, such as an oil cylinder, to control the relative positions of the first roller units 8.7 on both sides of the cable to adjust the straightening effect on the cable.

[0134] Reference Figure 19 and Figure 20 Specifically, the second incoming line module 9 includes:

[0135] Regarding the multiple inlet tubes 9.1 arranged at intervals in the direction of the cable entry, the third roller group 9.2 arranged between the inlet tubes 9.1, and the transmission assembly 9.3 that drives the third roller group 9.2 to rotate, the inlet tubes 9.1 allow the cable to pass through, and the cable is exposed between the inlet tubes 9.1 and abuts against the third roller group 9.2. The contact surface of the second roller unit 9.4 of the third roller group 9.2 is set to be flat, which is conducive to dispersing the inner core of the cable.

[0136] At least one of the inlet pipes 9.1 is provided with a guide wheel 9.7 that is in rolling contact with the cable. The guide wheel 9.7 is preferably arranged between the first inlet module 8 and the second inlet module 9.

[0137] Among them, the second roller unit 9.4 is arranged on the upper and lower sides of the cable, and the transmission assembly 9.3 includes a motor 9.31, a belt transmission part 9.32, a gear transmission part 9.33 and an active transmission part 9.34. The motor 9.31 transmits torque to the second roller unit 9.4 through the belt transmission part 9.32 and the gear transmission part 9.33. The active transmission part 9.34 includes a micro motor 9.31, which is independently connected to a second roller unit 9.4. The micro motor 9.31 is set close to the guide wheel 9.7 to improve the guidance and straightening effect of the cable, which is conducive to the smooth entry of the cable into the second incoming line module 9. It is achievable that the inner core inside the cable can be regularized through the differential speed between the micro motor 9.31 and the belt and gear transmission part 9.33.

[0138] like Figure 18 As shown, as a further implementation of the cable transfer module, the cable transfer module also includes a transversely arranged fourth transfer track 10, and multiple cable processing modules 11 are arranged about the fourth transfer track 10. The cable processing modules 11 and the cable stripping modules 15 are arranged in sequence about the fourth transfer track 10. The cable clamping module can travel on the second transfer track 3 and face the cable stripping module 15 and the second incoming line module 9. The cable enters the cable stripping module 15 under the action of the second incoming line module 9 and is connected with the cable clamping module to realize the transfer of the cable.

[0139] Among them, after the cable stripping module 15 cuts and strips the front end of the cable, the second incoming cable module 9 moves sequentially about the fourth transfer track 10, thereby passing through multiple cable processing modules 11 in sequence to complete the processing of the front end of the cable.

[0140] It should be pointed out that a movable module is connected between the fourth transfer track 10 and the second incoming line module 9, thereby allowing the driving end of the module to perform three-axis movement. The clamping action is preferably achieved by a pneumatic finger cylinder.

[0141] like Figure 21 and Figure 22As shown, the cable stripping module 15 includes a knife holder, a lower knife group 15.2 and an upper knife group 15.1 arranged vertically opposite to each other, a wire stripping assembly arranged on the knife holder, and a waste bin 15.3 covered on the side of the lower knife group 15.2. The upper knife group 15.1 is connected to the wire stripping assembly and is arranged above the knife holder, wherein the wire stripping assembly is used to drive the upper knife group 15.1 to move axially about the cable, thereby stripping the cable.

[0142] Specifically, the upper knife group 15.1 and the lower knife group 15.2 are axially distributed with a front knife, a middle knife and a rear knife about the cable, wherein the middle knife is used to cut the cable, the front knife is used to strip the front end of the cable, and the rear knife is used to strip the rear end of the cable.

[0143] Reference Figure 22 The wire stripping assembly includes a clamping cylinder 15.4 that can clamp the cable, a rack 15.5 connected to the clamping cylinder 15.4, and a driving gear 15.6 fixed to the tool holder. The gear rack 15.5 is actuated to drive the clamping cylinder 15.4 and the cable to perform a pulling action to facilitate the wire stripping work. The clamping cylinder 15.4 can be optionally a finger cylinder, and its action end is hinged with a clamping claw 15.7 group, which has the same structure as the action end of the cable clamping tool 4. The clamping claw 15.7 group is a conventional technical feature of cable clamping and will not be described in detail here.

[0144] Specifically, the cable processing module 11 includes a wire twisting claw 11.1, a rosin dipping chamber 11.2 and a tin dipping chamber 11.3. The wire twisting claw 11.1 is placed at the front end of the cable to hold the inner core tightly and collect the inner core into strands by rotating.

[0145] Specifically, the end of the incoming wire module is hinged with an outlet pipe 9.5, and a wire pressing cylinder 9.6 connected to the outlet pipe 9.5 is provided above the outlet pipe 9.5. The cable extends out of the outlet pipe 9.5, and the wire pressing cylinder 9.6 and the cable processing module 11 are arranged at the upper and lower ends of the cable relative to each other. After completing the wire twisting claw 11.1 process, the second incoming wire module 9 moves to the rosin dipping warehouse 11.2 or the tin dipping warehouse 11.3. At this time, the front end of the cable is driven downward by the action of the wire pressing cylinder 9.6, thereby entering the rosin dipping warehouse 11.2 or the tin dipping warehouse 11.3. The tin dipping warehouse 11.3 and the rosin sticking warehouse have been fully disclosed in the prior art and will not be described in detail here.

[0146] In addition, after completing the processing of the exposed part of the cable, it is necessary to pass through the terminal lug pressing station, which includes a terminal lug loading tray, and a terminal lug positioning tool, a terminal lug pressing tool arranged above the terminal lug positioning tool, first the terminal lug is transported from the terminal lug loading tray to the terminal lug positioning tool, and then the cable clamping tool clamps the cable end on the terminal lug on the terminal lug positioning tool, the terminal lug pressing tool moves downward, and the pressing head on it moves downward and presses the terminal lug, thereby forcing the terminal lug to clamp on the end of the cable, and finally the cable clamping tool transfers it to the first transfer track or the cable plugging tool.

[0147] Specifically, the terminal lug is a U-shaped piece with an upper opening, and the terminal lug pressing tool has a relative U-shaped pressing head. The opening of the U-shaped pressing head is downward and inwardly retracted, so that during the downward process, the U-shaped terminal lug is squeezed and guided to retract and hold the cable end.

[0148] The present invention also provides a processing technology for a single-head crimping terminal cable assembly machine, comprising:

[0149] Cable processing steps:

[0150] A1 Cable straightening and feeding: In the third transfer track 7, the cable is placed in alignment with the first guide port 8.4 at the rear end. The cable enters the feed track 8.1 under the force of the rear conveyor. As the cable enters the track, the compression modules 8.6 on the first and second roller groups 8.2 and 8.3 are controlled to move closer one by one. The cable is guided by the first and second roller groups 8.2 and 8.3, and is stretched and straightened after being subjected to forces in perpendicular directions.

[0151] As the cable moves forward, it passes through the second guide port 8.5 at the front end and enters the cable inlet pipe 9.1. It then moves towards the cable stripping station under the active roller pressure of the third roller group 9.2 until the front end of the cable enters the cable stripping station.

[0152] A2: The front end of the cable is stripped. The third roller group 9.2 stops moving. The cable stripping station includes a cable stripping module 15. The upper knife group 15.1 and the lower knife group 15.2 cut and press the cable. The movable stripping assembly clamps the cable and the inner core to cut the front end of the cable and strip the cable jacket and inner core to expose the inner core and wire at the front end of the cable.

[0153] A3 Cable front-end processing: Inside the fourth transfer track 10, the second incoming cable module 9 is transferred through the cable processing module 11. The cable processing module 11 includes a wire twisting claw 11.1, a rosin dipping chamber 11.2, and a tinning chamber. After completing the twisting, rosin dipping, and tinning of the cable, the fourth transfer track 10 transfers the second incoming cable module 9 back to the cable stripping station.

[0154] A4 cable fixed-length stripping: In the second transfer track 3, a cable clamping tool 4 is provided on it. The first incoming module 8 and the second incoming module 9 further feed the cable until the cable passes through the cable clamping tool 4 and reaches the desired length. At this time, the cable clamping tool 4 grabs the rear end of the cable, and the rear end of the cable is placed in the cable stripping station. The upper knife group 15.1 and the lower knife group 15.2 cut and press the cable. The movable stripping assembly clamps the cable and the inner core skin to achieve cutting of the cable front end, stripping of the cable jacket and the cable inner core, and exposing the inner core and wire at the rear end of the cable.

[0155] Cable assembly process:

[0157] C2 cable insertion, including a fifth transfer track covering the first transfer track 2 and the second transfer track 3, the fifth transfer track is provided with a cable plugging tool, the cable plugging tool having a front clamping end 16.1 and a rear clamping end 16.2, the front and rear clamping ends 16.2 respectively clamp the inner core and the wire at the rear end of the cable, wherein the front clamping end 16.1 is released before the rear clamping end 16.2, thereby transferring the cable until it is inserted into the terminal unit 5;

[0158] During assembly of the Class C2.1 terminal 5.4, the contouring module 6.1 drives the fixing frame 6.2 and the contouring member 6.3 downward until the contouring member 6.3 abuts against the upper end of the main body 5.2. The contouring module 6.1 drives the contouring member 6.3 to roll against the end surface of the main body 5.2 while maintaining contact therewith. The contouring member 6.3 forces the assembly portion 5.1 toward the opening 5.3, and the contouring member 6.3 exerts a force at the front end of the assembly portion 5.1 to close the assembly portion 5.1 within the opening 5.3.

[0159] C2.2 Class II terminal 5.5 is assembled, and the profiling action module 6.1 drives the fixed frame 6.2 and the profiling member 6.3 downward until the profiling member 6.3 abuts against the upper end of the assembly portion 5.1. The profiling member 6.3 is abutted by the assembly portion 5.1 and received in the fixed frame 6.2. A pushing portion facing the assembly portion 5.1 is formed between the fixed frame 6.2 and the profiling member 6.3, thereby correcting the assembly portion 5.1 to its first position on the assembly section 5.51.

[0160] The profiling action module 6.1 drives the fixed frame 6.2 and the profiling member 6.3 to translate, and the pushing portion pushes the assembly portion 5.1 to translate to the end of the assembly section 5.51. At this time, a vertical assembly gap is formed between the assembly portion 5.1 and the assembly section 5.51, and the second position of the assembly portion 5.1 on the assembly section 5.51 is corrected;

[0161] The contoured member 6.3 presses the assembly portion 5.1 vertically, forcing the assembly portion 5.1 to snap into place, so that the assembly portion 5.1 presses against the cables inside the assembly section 5.51, correcting the assembly portion 5.1 to the third position on the assembly section 5.51;
