Description

Technical Field

[0001] This utility model relates to the field of wire terminal crimping and adhesive shell application technology, and in particular to a wire and terminal positioning mechanism. Background Technology

[0002] Currently, the front terminal positioning in the market is a simple clamping positioning, which cannot control the positioning accuracy and makes the terminals prone to tilting, thus affecting the yield of terminal wire insertion into the shell. During the insertion process, the terminal wire is clamped by two cylinders pressing against each other, and the clamping force is restrained by the upper and lower cylinders, making it difficult to achieve balance. This results in slight changes in the height of the terminal wire, which also affects the yield of terminal wire insertion into the shell. The existence of these problems makes the connection between the terminal and the wire not firm enough, which can easily lead to an increase in the defect rate in the production process, thereby affecting production efficiency and product quality. Utility Model Content

[0003] Therefore, it is necessary to address the issue that during the insertion process, the clamping of the terminal wire involves two cylinders pressing against each other, resulting in a clamping force that is difficult to balance due to the mutual restraint between the upper and lower cylinders. This leads to slight variations in the height of the terminal wire and affects the yield rate of the terminal wire entering the shell. A wire and terminal positioning mechanism should be provided. After wire sorting, the terminal positioning accuracy can be controlled, the terminal insertion into the shell is more reliable and stable, the wire clamping can be synchronized, and the clamping force is easily adjustable and reliably stable. This improves the positioning accuracy of the wire and terminal, ensures the reliability and stability of the terminal insertion into the shell, and thus improves the efficiency of the entire production process and product quality.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wire and terminal positioning mechanism, comprising: a base plate, on which a wire organizing part and a terminal positioning part are provided that move in opposite directions. The terminal positioning part is located above the wire organizing part. The wire organizing part is used to comb the wire and isolate adjacent wires, and has a wire positioning comb. The terminal positioning part is used to fix the terminal and has a terminal positioning block. In a previous process, the wire is fed into the wire organizing part. The wire organizing part and the terminal positioning part move relative to each other simultaneously to pre-clamp the wire. In the previous process, the wire is pulled back so that the wire positioning comb can comb the wire. When the wire is combed, after the terminal is aligned with the terminal positioning block, the wire organizing part continues to lift to clamp and position the terminal. It also includes an upper and lower linkage structure, which is used to ensure the stability of the wire clamping part between the wire organizing part and the terminal positioning part.

[0005] Preferably, the upper end of the substrate has a right side plate and a left side plate on both sides, the right side plate and the left side plate are spaced apart, and an opening is formed between the right side plate and the left side plate. Both the right side plate and the left side plate are equipped with slide rails, and the right side plate, the left side plate and the substrate are integrated.

[0006] Preferably, the cable management unit includes a right cable management slider and a left cable management slider that are respectively slidably disposed on the right side plate and the left side plate. One end of the cable positioning comb is fixed to the right cable management slider. The left cable management slider is equipped with a lower cable clamping anti-slip plate, and the cable positioning comb is connected to the lower cable clamping anti-slip plate. A power source is provided on the base plate of the right cable management slider to drive the right cable management slider to reciprocate along the slide rail.

[0007] Preferably, the terminal positioning part includes a right fixed slider and a left fixed slider that are respectively slidably mounted on the right side plate and the left side plate. One end of the terminal positioning block is fixed to the right fixed slider. The left fixed slider is equipped with an upper wire clamping anti-slip plate. The terminal positioning block is fixed to the upper wire clamping anti-slip plate. Cylinders are provided on the top of the right side plate and the left side plate to drive the right fixed slider and the left fixed slider to reciprocate along the slide rail.

[0008] Preferably, the upper and lower linkage structure includes a mounting base, a first rack, a second rack, a gear shaft, and a bearing assembly. The mounting base is fixed on the left side plate and located between the left fixed slider and the left cable management slider. The mounting base is provided with a mounting hole. The bearing assembly is installed in the mounting hole, and the gear shaft is keyed to the bearing assembly. The first rack is located on the left fixed slider and meshes with the gear shaft. The second rack is located on the left cable management slider and meshes with the gear shaft.

[0009] Preferably, the upper and lower linkage structure further includes a guide rod and a compression spring. One end of the guide rod is fixed to the left-side cable management slider, and the other end of the guide rod slides through the mounting base. The compression spring is sleeved on the guide rod.

[0013] Preferably, the terminal positioning block is provided with a positioning groove corresponding to the combing area.

[0014] Compared to existing technologies, this invention offers the following advantages: Through the coordinated operation of the cable management section and the terminal positioning section, precise cable routing and stable terminal positioning are achieved. This coordinated operation ensures that the cable is in an ideal routing state before entering the terminal positioning section, thereby significantly improving the accuracy of the connection between the terminal and the cable. Furthermore, the synchronous movement of the cable management section and the terminal positioning section ensures that the cable remains stable when clamped, avoiding positioning deviations caused by cable movement and further improving the yield rate of terminal insertion into the housing.

[0015] Secondly, the design of the upper and lower linkage structure makes the clamping actions of the wire handling section and the terminal positioning section more coordinated and consistent. This linkage structure ensures the synchronous movement of the two parts through the meshing of the gear shaft and rack, thereby achieving uniform clamping of the wire. This uniform clamping not only improves the stability of clamping, but also effectively prevents the wire from slipping or deforming during the clamping process, ensuring the accuracy and reliability of terminal insertion.

[0016] Furthermore, the wire and terminal positioning mechanism of this invention also features adjustable clamping force. Through the included cylinder, the clamping force can be flexibly adjusted according to the material and thickness of different wires to meet various production needs. This adjustment function not only expands the applicability of the equipment but also effectively prevents wire damage or inaccurate terminal positioning caused by improper clamping force.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] Please see Figure 1 This embodiment provides a wire and terminal positioning mechanism, which includes a base plate 10. A wire management part 20 and a terminal positioning part 30 that can move towards each other are provided on the base plate 10. The terminal positioning part 30 is located on the upper part of the wire management part 20.

[0025] In this embodiment, please refer to Figure 4 The function of the substrate 10 is to connect with automated equipment and facilitate the fixing of other components to the equipment. The main structure of the substrate 10 is as follows: the upper end of the substrate 10 has a right side plate 11 and a left side plate 12. The substrate 10, the right side plate 11 and the left side plate 12 are all provided with mounting holes, and there is a mounting connection on the back of the substrate 10 to facilitate connection with the equipment. The right side plate 11 and the left side plate 12 are spaced apart, and a clearance is formed between the right side plate 11 and the left side plate 12. The right side plate 11 and the left side plate 12 are both equipped with slide rails 13. The right side plate 11, the left side plate 12 and the substrate 10 are integrated.

[0026] Please see Figure 2 The cable management section 20 is mainly used to comb the cables and isolate adjacent cables. In this embodiment, the main structure of the cable management section 20 is as follows: the cable management section 20 includes a right cable management slider 21, a left cable management slider 22, a cable positioning comb 23, a lower cable clamping anti-slip plate 24, and a power source 25. The right cable management slider 21 and the left cable management slider 22 are respectively slidably mounted on the corresponding slide rails 13 of the right side plate 11 and the left side plate 12. One end of the cable positioning comb 23 is fixed to the right cable management slider 21. The lower cable clamping anti-slip plate 24 is provided with a first anti-slip connecting plate. One end of the first anti-slip connecting plate is fixed to the left cable management slider 22, and the cable positioning comb 23 and the lower cable clamping anti-slip plate 24 are connected. The slide plate 24 is connected; a drive connection plate is provided on the right-side cable management slider 21, and a power source 25 is fixed on the base plate 10. The power source 25 is a motor, and the output end of the power source 25 is connected to the drive connection plate. The output end of the power source 25 is a lead screw. The drive connection plate is provided with a threaded hole that mates with the lead screw. The power source 25 drives the drive connection plate to drive the right-side cable management slider 21, and at the same time drives the right-side cable management slider 21 connected to the cable positioning comb 23 and the lower cable clamping anti-slip plate 24. This allows the cable positioning comb 23 and the lower cable clamping anti-slip plate 24 to move toward the terminal positioning part 30, thereby clamping and fixing the cable in conjunction with the terminal positioning part 30.

[0027] Furthermore, in an optional embodiment, in order to enable the wire positioning comb 23 to perform its wire combing function, please refer to... Figure 5The wire positioning comb 23 includes a comb body 230, a comb connecting plate 231, and a mounting groove. The comb body 230 is fixed on the mounting groove. The comb connecting plate 231 is connected to the lower clamping anti-slip plate 24. The comb body 230 has combing areas at equal intervals. Each combing area has several combing grooves 232 that can accommodate wires. In the current process, after the wire with the terminal is delivered between the wire handling part 20 and the terminal positioning part 30, the terminal positioning part 30 is pressed down. The power source 25 drives the wire positioning comb 23 to lift up and pre-clamp the wire, isolating the wires into the combing grooves 232. The wire feeding mechanism pulls the wire back, thereby realizing the combing of the wire positioning comb 23 on the wire, so that the center distance, angle, and front-back distance between the terminals all reach the preset values. At this time, the power source 25 drives the wire positioning comb 23 to continue to lift up to cooperate with the terminal positioning part 30 to fix the terminals. Then, the shell insertion action can be performed.

[0028] Please see Figure 3 and Figure 6 The terminal positioning part 30 mainly cooperates with the wire positioning comb 23 to fix the terminal. In this embodiment, the main structure of the terminal positioning part 30 is as follows: the terminal positioning part 30 includes a right fixed slider 31, a left fixed slider 32, an upper wire clamping anti-slip plate 33, and a terminal positioning block 34. The right fixed slider 31 and the left fixed slider 32 are respectively slidably mounted on the slide rails 13 of the right side plate 11 and the left side plate 12. One end of the terminal positioning block 34 is fixed to the right fixed slider 31. The terminal positioning block 34 is provided with a groove 340 corresponding to the combing area. The groove 340 mainly serves to... To achieve the function of avoiding positioning; the upper anti-slip plate 33 is provided with a second anti-slip connecting plate, one end of which is fixed on the left fixed slider 32, and the terminal positioning block 34 is fixed to the upper anti-slip plate 33; the top of the right plate 11 and the left plate 12 are provided with cylinders 35 that drive the right fixed slider 31 and the left fixed slider 32 to reciprocate along the slide rail 13, respectively. The two cylinders 35 drive the right fixed slider 31 and the left fixed slider 32 to clamp the terminal positioning block 34 and the upper anti-slip plate 33 with the wire positioning comb 23 and the lower anti-slip plate 24.

[0029] In an optional embodiment, both the upper wire clamping anti-slip plate 33 and the lower wire clamping anti-slip plate 24 are provided with anti-slip textures. When the upper wire clamping anti-slip plate 33 and the lower wire clamping anti-slip plate 24 clamp the wire, the friction is increased to prevent the wire from loosening, thereby improving the reliability and stability of the terminal insertion shell.

[0030] In an optional embodiment, in order to ensure the stability and durability of the mechanism, the terminal positioning part 30 further includes a buffer structure 36, which includes positioning blocks respectively disposed on the right side plate 11 and the left side plate 12, and buffers respectively disposed on the right side fixed slider 31 and the left side fixed slider 32 that cooperate with the positioning blocks.

[0031] In addition, the cable management unit 20 also includes a limiting sensor structure 26, which includes a sensing plate disposed on the right-side cable management slider 21 and a sensor disposed on the substrate 10 and electrically connected to the power source 25. By providing the buffer structure 36 and the limiting sensor structure 26, the impact force during the movement can be effectively absorbed, reducing equipment wear and extending service life. At the same time, these structures can also provide accurate positioning feedback, ensuring that the equipment maintains high precision and high stability during long-term operation.

[0032] To ensure the stability of the wire management section 20 and the terminal positioning section 30 when driving and clamping the wire, the wire and terminal positioning mechanism also includes an upper and lower linkage structure 40 provided on the substrate 10. Please refer to [link / reference]. Figure 2 The upper and lower linkage structure 40 includes a mounting base 41, a first rack 42, a second rack 43, a gear shaft 44, and a bearing assembly 45. The mounting base 41 is fixed to the left side plate 12 and located between the left fixed slider 32 and the left wire guiding slider 22. The mounting base 41 has mounting holes, and the bearing assembly 45 is installed in the mounting holes. The gear shaft 44 is keyed to the bearing assembly 45. The first rack 42 is located on the left fixed slider 32 and meshes with the gear shaft 44. The second rack 43 is located on the left wire guiding slider 22 and meshes with the gear shaft 44. Through the design of the upper and lower linkage structure 40, the clamping actions of the wire guiding part 20 and the terminal positioning part 30 are more coordinated and consistent. This linkage structure, through the meshing of the gear shaft 44 and the rack, ensures the synchronous movement of the two parts, thereby achieving uniform clamping of the wire. This uniform clamping not only improves the stability of clamping but also effectively prevents the wire from slipping or deforming during clamping, ensuring the accuracy and reliability of terminal insertion.

[0033] In addition, the upper and lower linkage structure 40 also includes a guide rod 46 and a compression spring 47. One end of the guide rod 46 is fixed to the left side cable management slider 22, and the other end of the guide rod 46 slides through the mounting base 41. The compression spring 47 is sleeved on the guide rod 46. Under the synergistic action of the guide rod 46 and the compression spring 47, the entire upper and lower linkage structure 40 can achieve stability, thereby ensuring the smooth operation of the entire linkage structure.

[0034] In summary, after the wire feeding mechanism in the preceding process delivers the wire with terminals to the wire management section 20 and the terminal positioning section 30, the cylinder 35 drives the terminal positioning block 34 to press down, and the motor drives the wire positioning comb 23 to lift up and pre-clamp the wire, isolating the wire into the combing grooves 232. The wire feeding mechanism pulls the wire back, thereby achieving the combing of the wire positioning comb 23, so that the center distance, angle, and front-to-back distance between the terminals all reach the preset values. At this time, the motor drives the wire positioning comb 23 to continue to lift up in conjunction with the terminal positioning block 34 to fix the terminal, and then the shell insertion action can be performed. Through the coordinated work of the wire management section 20 and the terminal positioning section 30, precise combing of the wire and stable positioning of the terminals are achieved. This coordinated working mode ensures that the wire reaches an ideal combing state before entering the terminal positioning section 30, thereby greatly improving the accuracy of the connection between the terminal and the wire. Furthermore, the synchronous movement of the wire management section 20 and the terminal positioning section 30 ensures that the wire remains stable when clamped, avoiding positioning deviations caused by wire movement and further improving the yield of terminal insertion housings.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
