Description

Technical Field

[0001] The invention relates to the technical field of shell inserting machines, in particular to a pre-pipe-insertion translation device of a shell inserting machine. Background Art

[0002] A wiring harness is a low-voltage assembly of wires that connects two or more isolated circuit boards or components, allowing current to flow and enabling the functions of each component. It is widely used in household appliances, lighting fixtures, digital products, and more.

[0003] In related technologies, the shell inserting machine generally includes a wire cutting and stripping mechanism, an end-piercing mechanism, and a shell inserting mechanism, which automatically inserts the shell into the end of the wire. However, for some electronic wire harnesses that need to be inserted into a casing and laser-coded, manual tube insertion is required, and then the shell is inserted, and then laser coding and twisting processes are performed, thereby reducing production efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a pre-pipe translation device for a shell inserting machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a front translation device for pipe threading of a shell inserting machine, comprising a support, a wire-passing duct linear module and a pipe-calibrating linear module provided on the surface of the support, the wire-passing duct linear module presses the wire to keep the wire neat, the pipe-calibrating linear module is installed with an assembly plate and a rear-end first wire clamping device is installed on the side of the assembly plate, the rear-end first wire clamping device and the side of the support are respectively installed with a front-end first wire clamping device and a second wire calibrator, the front-end first wire clamping device is installed with a positioning clamp and an anti-slip clamp, the front-end first wire clamping device drives the positioning clamp and the anti-slip clamp to clamp the wire, the second wire calibrator is connected to two clamping heads, the second wire calibrator drives the clamping head to clamp the wire, clamping the wire can stably drive the wire to move, and can also prevent the wire from bending;

[0006] The combined design of the positioning clamp and anti-slip clamp not only ensures the axial accuracy of the cable during movement through the positioning clamp, but also uses the texture of the anti-slip clamp to increase the friction with the cable surface, preventing the cable from slipping during movement. This can significantly improve the reliability of movement, especially for smooth-surfaced cables (such as nylon-sheathed cables).

[0007] The linear module is mounted on the assembly plate and is connected to a tube organizer located on the side of the first wire clamping device at the front end. The tube organizer positions the wire tube, and the linear module, the linear module, and the first wire clamping device at the rear end cooperate to realize the double movement of the wire, thereby increasing the moving range of the wire and meeting different processing requirements of the wire.

[0008] The coordinated action of the three linear modules adopts programmable control, and the movement speed and stroke can be flexibly adjusted according to parameters such as the processing length of the wire and the pipe penetration depth. For example, low-speed and high-precision mode is used for short-distance fine-tuning, and high-speed mode is switched for long-distance movement, which can not only ensure processing accuracy but also improve the overall processing rate.

[0009] Furthermore, the wire-passing duct linear module includes an upper pressing seat and a lower pressing seat and a first cylinder connected to the lower pressing seat. The upper pressing seat and the first cylinder are respectively installed on the upper surface and the lower surface of the support. The lower pressing seat is slidably connected to the inside of the upper pressing seat. The wire passes between the upper pressing seat and the lower pressing seat. The first cylinder controls the spacing between the upper pressing seat and the lower pressing seat, which can maintain the stability of the wire movement and prevent the wire from bending significantly and entangled with each other. The contact surface between the upper pressing seat and the lower pressing seat is made of aluminum alloy and is polished to reduce the friction resistance of the wire during movement, prevent scratching the wire, and reduce the wear on the wire surface; it can limit the position of wires of different thicknesses to adapt to wires of various thicknesses.

[0010] Furthermore, the first wire clamping device at the front end and the second wire aligner have the same structure and include a second cylinder. The second cylinder is connected to an articulated seat, and two driving arms are rotatably installed on the articulated seat. A V-shaped movable arm is rotatably installed between the second cylinder and the two driving arms. The second cylinder is used to automatically clamp the wire, and the wire clamping is stable. Self-lubricating bearings are used at the rotating connection between the V-shaped movable arm and the driving arm to reduce mechanical wear while ensuring the smoothness of the clamping action. The two driving arms are symmetrically designed, which can evenly distribute the clamping force on the wire and avoid deformation of the wire due to excessive local force. It is especially suitable for processing thin wires.

[0011] Furthermore, a fourth linear module is installed in the middle of the support surface, and the fourth linear module is installed with a wire tube mounting seat through a slide. The wire tube mounting seat has several wire tube holes. The wire tube mounting seat can control the spacing of the wires. The fourth linear module controls the wire tube to move along the wire, which can organize the wires in a larger range. The inner wall of the wire tube mounting hole adopts a smooth polytetrafluoroethylene coating, which can reduce the friction coefficient when the wire passes through and reduce the friction between the wire and the wire tube.

[0012] Furthermore, the support surface has a wire passing plate, which has several pipe mounting holes. In conjunction with the wire pipe mounting seat, several wires can be separated at equal distances. The circular hole layout of the wire passing plate corresponds one-to-one with the pipe mounting holes of the wire pipe mounting seat, forming a double positioning structure, which can effectively prevent the wires from being entangled or offset during the movement of the wires; the wire passing plate adopts a detachable design and is fixed with bolts. When different numbers of wires need to be processed, it is only necessary to replace the wire passing plate with the corresponding number of circular holes, which is convenient to operate and improves versatility.

[0013] Furthermore, the pipe handler includes a clamping electric cylinder, and two pipe handling clamps are installed at the output end of the clamping electric cylinder. The pipe handling clamps have a V-shaped mouth, which can assist in clamping the wire. The clamping electric cylinder adopts servo control and can automatically adjust the clamping force according to the diameter of the wire to achieve flexible clamping and avoid damage to the wire. The angle of the V-shaped mouth has been optimized and opened at about 60 degrees, which can adapt to wires of different diameters and ensure that the wire is automatically centered when clamped, preventing deviation of the movement trajectory due to deflection and improving the consistency of wire movement.

[0014] Furthermore, the calibration linear module, linear module, first wire clamping device at the rear end, and fourth linear module are equipped with photoelectric switches. The photoelectric switches control the stopping of the calibration linear module, linear module, first wire clamping device at the rear end, and fourth linear module, thereby improving the operation accuracy and ensuring the stable movement accuracy of the wire and the precise insertion of the wire into the shell. The photoelectric switch adopts a non-contact detection method with a response time as short as 0.1ms. It can monitor the moving position of each linear module in real time, and cooperate with the PLC control system to form a closed-loop feedback to achieve millimeter-level positioning accuracy.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The clamping electric cylinder controls the positioning of the wire tube by the pipe handler, and the linear module controls the movement of the clamping electric cylinder to realize the movement of the wire. The front first wire clamping device controls the anti-slip clamp and the positioning clamp to clamp the wire together. The rear first wire clamping device controls the movement of the front first wire clamping device to realize the movement of the wire. The anti-slip clamp and the positioning clamp cooperate with the pipe handler to prevent the soft wire from bending when the wire moves. The calibration linear module controls the movement of the linear module and the rear first wire clamping device to realize the secondary movement of the wire, improve the accuracy and flexibility of the wire plug-in, realize automatic pipe threading, and high efficiency of wire plug-in. The coordinated action of multiple linear modules can preset multiple movement paths through programming to meet the processing and plug-in requirements of wires of different lengths. No manual adjustment is required, which reduces the dependence on the operator's skill level; and the fully automated operation mode can realize a continuous and uninterrupted processing process.

[0017] (2) The upper and lower clamping seats are used to preliminarily comb the wires. The wires pass through the pipe holes and the wire pipe holes to maintain the spacing of the wires. The clamping heads clamp the wires to keep the wires in a tensioned state, preventing the wires from falling and bending. The wires move stably. At the same time, the multiple constraints of each component on the wires can effectively reduce the position deviation of the wires caused by vibration and impact during processing, ensure the processing consistency of each wire, and reduce the defective rate of the product. The clamping and positioning method of the fully mechanical structure is not affected by the ambient temperature and humidity. The equipment has higher operating stability and is suitable for long-term use in complex working conditions such as workshops. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] 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.

[0025] Example:

[0026] See also Figure 1-5 The present invention provides a technical solution: a pre-pipe translation device for a shell inserting machine, comprising a support 1. The support 1 serves as a basic bearing structure, and its flat surface can ensure the horizontal installation of various components and reduce the deviation of wire movement caused by installation tilt. The various components are mainly fixed by bolts. The support 1 can be installed with a linear module to control the movement of the entire translation device, so that the wire can be processed at different stations.

[0027] The surface of the support 1 is provided with a wire-passing duct linear module and a calibration pipe linear module 2. The wire-passing duct linear module presses the wire and can comb the wire. The wire-passing duct linear module constrains the wire to prevent the wire from being stacked in a disorderly manner. The calibration pipe linear module 2 is installed with an assembly plate 4 and a rear-end first wire clamping device 5 is installed on the side of the assembly plate 4. The rear-end first wire clamping device 5 and the side of the support 1 are respectively installed with a front-end first wire clamping device 9 and a second calibration device 10. The front-end first wire clamping device 9 is installed with a positioning clamp 18 and an anti-slip clamp 17. The front-end first wire clamping device 9 drives the positioning clamp 18 and the anti-slip clamp 17 to clamp the wire. The positioning clamp 18 is provided with four notches, which are adapted to the shape of the wire. The anti-slip clamp 17 is processed with a rack. The rack of the anti-slip clamp 17 increases friction and can stably clamp the wire.

[0028] The second straightener 10 is connected to two clamping heads 21. The second straightener 10 drives the clamping heads 21 to clamp the wire. The upper clamping head 21 is provided with a rack, and the lower clamping head 21 is a flat surface. When clamping the wire, the wire can be prevented from being damaged.

[0029] The linear module 3 is installed on the assembly plate 4. The linear module 3 is connected to a pipe manager, and the pipe manager is located on the side of the first wire clamping device 9 at the front end. The pipe manager positions the wire pipe and can maintain the tension of the wire. By fine-tuning the tension in real time, the wire can be prevented from sagging due to its own weight.

[0030] In this embodiment, if Figure 2 As shown, the wire-passing conduit linear module includes an upper pressing seat 11 and a lower pressing seat 13 and a first cylinder 12 connected to the lower pressing seat 13. The upper pressing seat 11 and the first cylinder 12 are respectively mounted on the upper surface and the lower surface of the support 1. The lower pressing seat 13 is slidably connected to the inside of the upper pressing seat 11. The first cylinder 12 controls the lower pressing seat 13 to move up and down, and can change the distance between the lower pressing seat 13 and the upper pressing seat 11. The wire passes through the upper pressing seat 11 and the lower pressing seat 13 for basic combing;

[0031] The upper pressing seat 11 and the lower pressing seat 13 form a channel. When the first cylinder 12 drives the lower pressing seat 13 to slide up and down, the clamping force can be dynamically adjusted according to the wire diameter. When the wire is thicker, the spacing is increased to prevent squeezing. When the wire is thinner, the spacing is reduced to prevent the wire from shaking.

[0032] In this embodiment, if Figure 4 and Figure 5As shown, the front-end first wire clamping device 9 and the second wire aligner 10 have the same structure and include a second cylinder 22. The second cylinder 22 is connected to a hinged seat 23. Two driving arms 20 are rotatably installed on the hinged seat 23. A V-shaped movable arm 19 is rotatably installed between the second cylinder 22 and the two driving arms 20. When the second cylinder 22 controls the movement of the V-shaped movable arm 19, the opening or closing of the V-shaped movable arm 19 can control the rotation of the driving arm 20. The driving arm 20 drives the clamping head 21 to open and close to achieve the clamping of the wire. The second cylinder 22 drives the driving arm 20 through the V-shaped movable arm 19. The V-shaped structure makes the clamping force symmetrically distributed, ensuring that the wire is always in the center position when clamped to avoid unilateral offset.

[0033] In this embodiment, if Figure 2 As shown, a fourth linear module 6 is installed in the middle of the surface of the support 1, and a wire pipe mounting seat 8 is installed on the fourth linear module 6 through a slide 7. The wire pipe mounting seat 8 has a plurality of wire pipe holes. The clamping head 21 is located between the wire pipe mounting seat 8 and the wire passing plate 14. The fourth linear module 6 drives the wire pipe mounting seat 8 to move along the direction of the wire. The pipe mounting holes form multi-point support for the wire, and cooperate with the fixed spacing of the circular holes of the wire passing plate 14 to realize a dual anti-drooping structure of dynamic support and static positioning.

[0034] In this embodiment, if Figure 2 As shown, the support 1 has a wire plate 14 on its surface. The wire plate 14 has a plurality of pipe holes, which can maintain the spacing between adjacent wires and ensure that the wires do not contact each other.

[0035] In this embodiment, if Figure 3 As shown, the pipe handler includes a clamping electric cylinder 15, and two pipe handlers 16 are installed at the output end of the clamping electric cylinder 15. The pipe handler 16 has a V-shaped mouth. The two pipe handlers 16 can stably clamp the wires through the V-shaped mouth. Adaptive clamping is achieved by the two V-shaped mouth pipe handlers 16. The V-shaped angle can naturally guide the wires to return to the center, and stable grasping can be achieved even if there are slight differences in the wire diameters.

[0036] In this embodiment, the calibration linear module 2, the linear module 3, the first rear-end clamping device 5, and the fourth linear module 6 are equipped with a photoelectric switch 24, which controls the stopping of the calibration linear module 2, the linear module 3, the first rear-end clamping device 5, and the fourth linear module 6;

[0037] A moving piece is set to move the calibration linear module 2, the linear module 3, the first wire clamping device 5 at the rear end, and the fourth linear module 6. The moving piece moves to the photoelectric switch 24, and the calibration linear module 2, the linear module 3, the first wire clamping device 5 at the rear end, and the fourth linear module 6 stop working. The operation accuracy is high, and the module overtravel collision is avoided. At the same time, the signal linkage of the multi-module switch is used to achieve precise connection of the actions of each component and reduce coordination errors.

[0038] Specifically, when in use, four wires pass between the upper pressing seat 11 and the lower pressing seat 13, and then the wires pass through the wire plate 14 and the wire tube mounting seat 8, and one end of the wire is pulled between the positioning clamp 18 and the anti-slip clamp 17;

[0039] The first wire clamping device 9 at the front end drives the anti-slip clamp 17 and the positioning clamp 18 to close through the V-shaped movable arm 19 and the driving arm 20, thereby clamping the wire. The clamping electric cylinder 15 controls the tube organizer 16 to clamp the wire, thereby doubly clamping the wire.

[0040] The calibration linear module 2 drives the linear module 3 and the rear-end first clamping device 5 to move by controlling the assembly plate 4 to realize the first movement of the wire. At this time, the clamping head 21 does not clamp the wire to ensure that the wire can move. The linear module 3 controls the clamping electric cylinder 15 to move, and the front-end first clamping device 9 of the rear-end first clamping device 5 moves to realize the second movement of the wire. The wire movement range is larger. When the wire is moved into place, the second calibration device 10 controls the clamping head 21 to clamp the wire in time to prevent the wire from falling and bending, and keep the wire in a tensioned state. The wire is not easily contacted and worn by the support 1 during movement.

[0041] The four wires are initially straightened by the wire guide tube linear module, the wire passing plate 14 and the wire guide mounting seat 8 are separated by a distance, the first wire clamping device 9 and the wire organizer at the front end dually fix the wires, and the stroke is expanded by step-by-step movement of multiple modules. After they are in place, the second wire aligner 10 is fixed for the second time, reducing the contact wear between the wires and the support 1 throughout the process and ensuring the processing quality.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
