Description

Technical Field

[0001] This application relates to the technical field of wire terminal installation, and particularly to a multi-wire diameter wire terminal crimping device and method. Background Art

[0002] When installing an insulated-sheath terminal on a wire with an insulating skin, it is necessary to strip off the insulating skin of a set length at the front end of the wire to leave the wire core. Through a guide, the wire core is fed into the insulating sheath at the rear end of the terminal and then into the metal part at the front end of the terminal. Part of the insulating skin can also enter the insulating sheath. Then, the metal part is deformed by pressure through crimping. Different types of wires require different types of guides to ensure that the insulating skin can enter the insulating sheath of the terminal through the guide tube. In production, different types of guides need to be prepared, and the installation and disassembly are time-consuming and laborious. Summary of the Invention

[0003] An embodiment of this application provides a multi-wire diameter wire terminal crimping device and method, which solves the problem that the existing crimping device cannot be applied to wires and terminals of various specifications and improves production efficiency.

[0004] In a first aspect, an embodiment of this application provides a multi-wire diameter wire terminal crimping device, which includes a guiding and crimping assembly, specifically including: a guiding clamp, a crimper, a proximity mechanism, and a control module. The guiding clamp is arranged at the opening of the crimper. When the guiding clamp is closed, an introducing tube is formed. The proximity mechanism is used to drive the guiding clamp and the crimper to move axially in the introducing tube. The control module is used to control the first-stage translation of the guiding clamp in the axial direction of the introducing tube after the guiding clamp is closed, the second-stage translation of the guiding clamp in the axial direction of the introducing tube after the guiding clamp is opened, and is also used to control the crimper to generate a force for compressing the terminal to deform after the translation stops.

[0005] Further, it further includes a first driver and a second driver. The first driver is used to provide a first clamping force for the crimper during the first-stage translation and the second-stage translation. The second driver is used to provide a second clamping force for the crimper after the translation stops. The second clamping force is used to compress the terminal to deform and is greater than the first clamping force.

[0006] In one of the embodiments, the crimper includes a plurality of crimping heads around a center point to achieve variable-diameter clamping.

[0007] Preferably, the introducing tube includes a horn-shaped structure. The opening at one end of the horn-shaped structure away from the crimper is larger than the maximum outer diameter of the insulating skin of the wire that can be processed, and the opening at the other end of the horn-shaped structure is larger than the maximum core diameter of the wire that can be processed.

[0008] In one embodiment, it further includes a material taking gripper, a material taking driver group, a switching component and a feeder. The material taking gripper moves back and forth between the feeder and the guiding and crimping component under the drive of the material taking driver group. The switching component is used to drive the guiding and crimping component to switch between the crimping working position and the terminal loading working position.

[0009] Preferably, the switching component is used to drive the guiding and crimping component to rotate until the opening of the crimper faces upward.

[0010] In one embodiment, the material taking driver group includes a third driver, a fourth driver and a fifth driver. The third driver is used to control the opening and closing of the material taking gripper. The fourth driver is used to move the material taking gripper to switch between approaching the crimper and approaching the feeder. The fifth driver is used to move the material taking gripper to switch between moving away from or approaching the crimper.

[0011] Second, the embodiment of the present application also provides a method for crimping multi-diameter wire terminals. Using the multi-diameter wire terminal crimping device described in any one of the embodiments of the first aspect, it includes the steps:

[0012] Through the approaching mechanism, the bare wire core at the end of the wire enters the terminal insulation sheath through the guiding tube;

[0013] At the end of the first-stage translation, the guiding gripper opens;

[0014] At the end of the second-stage translation, the second driver provides pressure to deform the terminal for the crimper.

[0015] In one embodiment, the first-stage translation and the second-stage translation include at least one of the following:

[0016] When the first-stage translation occurs, the wire core enters the insulation sheath of the terminal;

[0017] When the first-stage translation occurs, the part of the wire with insulation is less than a set threshold distance from the insulation sheath;

[0018] When the second-stage translation occurs, the part with insulation enters the insulation sheath of the terminal.

[0019] In one embodiment, the guiding and crimping component loads the terminal, including the steps:

[0020] The guiding and crimping component is in the terminal loading working position, and the guiding gripper and the crimper are opened;

[0021] The material taking gripper clamps the terminal at the feeder and moves it to be directly opposite the crimper. The crimper closes to clamp the terminal; the guiding gripper closes, and one end of the guiding tube is aligned with the opening of the insulation sheath;

[0022] The switching component moves the guiding and crimping component to the crimping working position.

[0023] The above at least one technical solution adopted in the embodiments of the present application can achieve the following beneficial effects:

[0024] The present application only requires one type of guiding gripper. Through two-stage guiding process control, it can be applicable to various types of wires; the crimper applies pressure through drivers with different pressures to complete the clamping and crimping processes; during the opening and closing processes of the crimper, the opening aperture changes to adapt to different terminal structure sizes, avoiding deviations in terminal alignment.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments of this application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0035] The following will, in conjunction with the drawings, elaborate on the technical solutions provided by each embodiment of this application.

[0036] Figure 1 It is a schematic diagram of the terminal structure applicable to the device of this application.

[0037] The terminal includes an insulating sheath and a metal part, and the two are joined to form a tubular shape. During crimping, the end of the wire extends into the insulating sheath, and the wire and the metal part are crimped together.

[0038] The wire of this application includes an insulating skin and a wire core. When applying the device of this application, one end of the wire guided into the terminal has a part of the insulating skin stripped off to form the skin end and the core end of the wire. The skin end is the end of the insulating skin, and the core end is the end of the exposed wire core. The exposed part of the wire core is between the two.

[0039] Figure 2 It is a structural diagram of a multi-diameter wire terminal crimping device provided by an embodiment of this application, which includes a guiding and crimping assembly 1, specifically including: a guiding gripper 11, a crimper 12, a proximity mechanism 15, and a control module 16. A guiding gripper combined with the crimper into an integral assembly is provided at the opening of the crimper. The crimper is used to hold the terminal facing the inlet tube. When the guiding gripper is closed, it forms the inlet tube.

[0040] The dotted lines in the figure represent the mechanical drive connection relationship. The proximity mechanism is used to drive the guiding gripper and the crimper to move axially along the inlet tube. Conversely, the wire core at the end of the wire is made to approach the terminal along the inlet tube until it enters the insulating sheath, and when moving further, the wire core enters the metal part along the insulating sheath.

[0041] During the installation of the terminal at the end of the wire in this application, the proximity mechanism is used to perform any one of the following functions: pushing the integral assembly of the crimper and the guiding gripper towards the end of the wire; moving the end of the wire towards the guiding gripper and the crimper.

[0042] For example, the proximity mechanism is a cylinder, and the cylinder drives the crimper and the guiding gripper to move closer to or away from the end of the wire.

[0043] For another example, the proximity mechanism includes a stepper motor. The stepper motor drives a linear lead screw, and then the linear lead screw drives the crimper and the guiding gripper to move closer to or away from the end of the wire.

[0044] The solid line connections in the figure represent the control signal connection relationships. The control module is used to control the axial translation of the component in the inlet tube. Those skilled in the art can understand that for importing wires and crimp terminals, the translation described in this application is in the direction opposite to the wire. In one embodiment, it is used to control the first-stage translation in the axial direction of the inlet tube after the guiding gripper is closed, and the second-stage translation in the axial direction of the inlet tube after the guiding gripper is opened. The control module is also used to control the force generated by the crimper to cause deformation of the compression terminal after the translation stops.

[0045] Since the guiding gripper opens in the second stage and there is no restriction from the limiting part at the narrow end of the guiding tube, it can be ensured that after the wire core (core end) without the insulating skin enters the insulating sheath, the subsequent part with the insulating skin can also enter the insulating sheath. Therefore, it is not necessary to specifically configure corresponding guiding grippers for each type of wire. Of course, if the outer diameter of the part with the insulating skin is small enough to pass through the limiting part at the narrow end of the guiding tube, the guiding gripper may not open.

[0046] The control module can control the moving distance of the approaching mechanism according to the length of the exposed wire core of the wire. For example, by receiving GUI instructions, the control module determines the scales of the first-stage translation and the second-stage translation. The distances of the first-stage translation and the second-stage translation are set according to the instructions. Further, the working process of the approaching mechanism is determined.

[0047] For example, the first-stage translation is the process from when the guiding gripper and the crimper approach the wire until the core end passes through the inlet tube of the guiding gripper and enters the terminal insulating sheath. The end of the first-stage translation can end when all the exposed wire cores pass through the guiding gripper, or can end at any moment during the process from the moment the core end enters the terminal insulating sheath to when all the exposed wire cores pass through the guiding gripper. No further limitation is made here. When the second-stage translation ends, at least a part of the exposed wire core enters the metal part of the terminal.

[0048] Further, as Figure 2 shown, the guiding and crimping assembly further includes a guiding gripper driver 13. The guiding gripper driver is controlled by the control module to provide the force for clamping and opening the guiding gripper. In one embodiment, the guiding gripper is closed during the first-stage translation and opened during the second-stage translation.

[0049] Further, the guiding and crimping assembly further includes a crimper driver 14; the crimper driver is controlled by the control module and is used to provide the clamping force for the crimper.

[0050] Each driver in this application can include a cylinder or a motor, and no specific limitation is made.

[0051] Figure 3 This is a diagram of the guide gripper structure provided in the embodiment of the present application. Figure 3 As shown, the guide clamp comprises two arms 111 and 112, and grooves 113 are arranged on the clamping surfaces opposite to each other of the two arms, so that an introduction tube is formed when the guide clamp is closed.

[0052] The introduction tube is used to guide one end of the wire core of the wire into the insulating sheath of the terminal.

[0053] The side of the introduction tube that meets the wire, that is, the side away from the crimper, needs to have a relatively large inner diameter to ensure that the wire can enter. The inner diameter of the opening at the other end needs to be no larger than the inner diameter of the insulating sheath of the terminal. The two openings cooperate to guide the wire into the insulating sheath of the terminal. Preferably, the introduction tube includes a trumpet-shaped structure, the trumpet-shaped structure has a larger opening at one end away from the crimper and a smaller opening at the other end. The opening of the trumpet-shaped structure at one end away from the crimper is larger than the maximum outer diameter of the insulation skin of the processable wire, and the opening of the other end of the trumpet-shaped structure is larger than the maximum core diameter of the processable wire.

[0054] In one embodiment, the introduction tube comprises an integrally formed introduction portion 1131 and a limiting portion 1132. The introduction portion is a trumpet-shaped structure, with a large opening at one end away from the crimper and a small opening at one end connected to the limiting portion.

[0055] The limiting part arranged on the side of the introduction tube close to the crimper is a circular hole with the same diameter as the narrow end of the introduction tube, and the diameter is larger than the core end diameter, and larger or smaller than the skin end diameter. That is to say, when the guide clamp is suitable for wires of multiple wire diameters, the diameter of the hole can be larger than the smallest processable wire insulation outer diameter or smaller than the processable wire insulation outer diameter.

[0056] It should be noted that when the aperture of the limiting portion is smaller than the outer diameter of the machinable wire insulation skin, the controller controls the guide clamp to open and then perform the second stage translation in the axial direction of the guide tube; the relative position of the limiting portion and the skin end is used to divide the first stage translation and the second stage translation, and the first stage translation ends before the skin end and the limiting portion contact.

[0057] Preferably, the inner diameter of the limiting portion is smaller than the inner diameter of the insulating sheath. When the inner diameter of the limiting portion is smaller than the inner diameter of the insulating sheath, the two are relative, and the wire goes deep into the terminal without bending the wire by pressing against the front edge of the insulating sheath when feeding the wire through the limiting portion pipeline due to the small inner diameter of the insulating sheath.

[0058] Further, a receiving portion 1133 is provided at one end of the inlet pipe close to the crimper. In one embodiment, the receiving portion is provided on the side of the limiting portion away from the inlet portion for receiving the insulating sheath of the terminal. The diameter of the receiving portion is slightly larger than that of the insulating sheath of the terminal. When introducing the wire, a part of the insulating sheath of the terminal extends into the receiving portion. In some embodiments, the receiving portion is not necessary. In one embodiment, a stepped hole is provided at one end of the inlet pipe close to the crimper as the receiving portion for receiving the insulating sheath of the terminal, and the bottom hole of the stepped hole forms the limiting portion, and its aperture is the same as that of the narrow end of the inlet pipe.

[0059] Figure 4 The structural diagram of the crimper provided by the embodiment of the present application. As Figure 4 shown, the crimper includes a plurality of crimping heads 121 that synchronously expand and contract around the center point to achieve variable-diameter clamping. Since less than four crimping heads cannot ensure that the terminal is stressed on all four sides, preferably, the number of crimping heads is four. In one embodiment, the crimping heads rotate and clamp along a spiral movement track. The four crimping heads rotate perpendicular to the axial direction of the terminal, and the control module controls the driver to provide pressure, and each crimping head synchronously expands and contracts under the drive of the crimper driver to clamp the terminal.

[0060] The portion of the terminal being clamped is the metal portion at the end of the terminal.

[0061] For example, during the crimping operation, one end of the inlet pipe of the guiding gripper faces the direction of the wire incoming material, and the other end is aligned with the center point of the surrounding holes of each crimping head on the crimper.

[0062] Figure 5 The structural diagram of a multi-diameter wire terminal crimping device provided by the embodiment of the present application includes a guiding and crimping assembly, and also includes a picking gripper 2, a picking driver group 3, a switching assembly 4, and a feeder 5.

[0063] The picking gripper moves back and forth between the feeder and the guiding and crimping assembly under the drive of the picking driver group. It clamps the terminal from the feeder and sends it to the guiding and crimping assembly, and inserts the front metal section of the terminal into the crimper.

[0064] The switching assembly is used to drive the guiding and crimping assembly to switch between the crimping working position and the terminal loading working position. The crimping working position is the working position where the guiding and crimping assembly crimps the wire. The terminal loading working position is the working position for loading the terminal into the guiding and crimping assembly. Specifically, the guiding and crimping assembly clamps the terminal on the crimper at the terminal loading working position, and the guiding and crimping assembly returns to the crimping working position with the terminal to complete the process of the wire entering the terminal and being crimped. Then the guiding and crimping assembly returns to the terminal loading working position again to reload the terminal, and so on.

[0065] To achieve the above object, the switching component can drive the guiding and crimping component to translate or rotate. However, rotation is beneficial for space utilization and can reduce the size of the device in the specific embodiments of the present application. Therefore, preferably, the switching component drives the guiding and crimping component to rotate until the opening faces upward to approach the feeder.

[0066] Figure 6 Schematic diagram of the state switching of the multi-diameter wire terminal crimping device provided by the embodiment of the present application. The terminal loading working position and the crimping working position are as Figure 6 shown by the dashed boxes. Figure 6 The guiding and crimping component in it rotates around the straight line 72 in the figure as the axis to switch between the two working positions. Figure 6 The wire feeding port 71 is also shown in it, which is used to feed wire into the device from the outside of the machine. When the wire feeding port, the guiding tube and the opening of the crimper are in a straight line, the guiding and crimping component is in the crimping working position. When the guiding tube and the preliminary opening of the press face upward, it is in the terminal loading working position.

[0067] As Figures 5 - 6 shown, in one of the embodiments, the crimper driver includes a first driver 141 and a second driver 142.

[0068] The first driver is used to provide a first clamping force for the crimper during the first-stage translation and the second-stage translation.

[0069] For example, the first driver is arranged on the side of the crimper away from the guiding gripper. The output end of the first driver contacts the first force-bearing end extending from the crimper to apply a first clamping force to the crimper, and according to the instruction of the control module, the clamping and opening movements of the crimper are completed.

[0070] The second driver is used to provide a second clamping force for the crimper after the translation stops. The second driver is arranged on the side of the track where the approaching mechanism drives the crimper to move. In the crimping working position, combined with Figures 5 - 6 , when the crimper moves to the end of the wire core, that is, the position where the translation ends, the output end 1421 of the second driver enters the groove 122 of the crimper (the groove is shown in Figure 4 ), and abuts against the second force-bearing end in the groove to provide a second clamping force for the crimping head.

[0071] The second clamping force is greater than the first clamping force. It should be noted that the first driver has a relatively small power, and the first clamping force it provides can only ensure that the crimper holds the terminal, and cannot cause the deformation of the terminal. The second driver has a relatively large power, and the second clamping force it provides can cause permanent deformation of the terminal to achieve the crimping operation.

[0072] In one of the embodiments, asFigures 5 - 6 As shown, the material taking driver group includes a third driver 31, a fourth driver 32, and a fifth driver 33. The third driver is used to control the opening and closing of the material taking gripper. The fourth driver is used to move the material taking gripper to switch between being opposite to the crimper or being opposite to the feeder, specifically as Figure 5 shown in the movement trajectory of the fourth driver. The fifth driver is used to move the material taking gripper to switch between being away from or approaching the crimper, such as Figure 6 shown in the movement trajectory of the fifth driver in the direction perpendicular to the horizontal plane.

[0073] For example, the switching component drives the guiding and crimping component to rotate upward, so that the inlet pipe of the guiding gripper of the guiding and crimping component opens upward. When the feeder provides the terminals, the metal section of the terminal passes through the through hole provided in the feeder, ensuring that the opening of the insulating sheath of the terminal faces upward. Then, the third driver drives the material taking gripper to clamp the insulating sheath part, and the fifth driver drives the material taking gripper to move away from the feeder, pulling out the metal section of the terminal from the through hole in the feeder, and the fourth driver drives the material taking gripper to move above the guiding gripper and the crimper.

[0074] Figure 7 The following is a flowchart of a multi-wire diameter wire terminal crimping method provided by an embodiment of the present application. Using the multi-wire diameter wire terminal crimping device described in any embodiment of the present application, it includes the following steps:

[0075] Step 510: Make the exposed wire core at the end of the wire enter the terminal insulating sheath through the inlet pipe by means of the approaching mechanism.

[0076] In step 510, the control module sends an industrial control signal to the approaching mechanism, and the approaching mechanism drives the crimper and the guiding gripper as a whole to move closer to the end of the wire, and the guiding gripper clamps to form an inlet pipe to accommodate the end of the wire to enter.

[0077] Step 520: In response to the end of the first-stage translation, the guiding gripper opens.

[0078] The driving module drives the crimper and the guiding gripper to move closer to the wire. When the first-stage translation ends, the wire core enters the insulating sheath of the terminal. Or, when the first-stage translation ends, the part of the wire with the insulating skin (skin end) is less than the set threshold distance from the insulating sheath.

[0079] The control module sends an industrial control signal to the guiding gripper driver, and the guiding gripper driver drives the two arms of the gripper to open.

[0080] Since when the wire core enters the insulating sheath of the terminal, the guiding function of the guiding gripper is no longer needed, at this time the guiding gripper can be opened, and the wire will subsequently enter the terminal along with the wire core.

[0081] Due to the flared inlet part of the guiding gripper, when the aperture of the limiting part at the narrow end is larger than the outer diameter of the wire insulation sheath, at the end of the first-stage translation, the insulation sheath does not touch the pipe wall of the flared structure of the guiding gripper, and at the end of the first-stage translation, the guiding gripper opens.

[0082] Step 530: In response to the end of the second-stage translation, the second driver provides pressure to the crimper to deform the terminal.

[0083] During the second-stage translation, the part of the wire with the insulation sheath enters the insulation sheath of the terminal.

[0084] The approaching mechanism drives the crimper and the guiding gripper to move towards the wire until the end of the second-stage translation, and the core end enters the front metal part of the terminal.

[0085] For example, when the bare wire cores all enter the terminal metal part, at this time, the pressing deformation of the front end of the terminal is completed, and the connection between the terminal and the wire can be completed. Therefore, in one embodiment, at the end of the second-stage translation, the wire cores of the exposed part at the end of the wire completely enter the terminal metal part.

[0086] Figure 8 The process flow chart of filling the terminal by the guiding crimping assembly provided by the embodiment of the present application includes the steps:

[0087] Step 610: The guiding crimping assembly is in the working position of loading the terminal, and the guiding gripper and the crimper are opened.

[0088] For example, driven by the switching assembly, the guiding gripper and the crimper of the guiding crimping assembly open upwards. At this time, the guiding gripper and the crimper are opened to ensure that the metal section of the terminal can directly enter the crimper.

[0089] Step 620: The picking gripper clamps the terminal at the feeder and moves it to face the crimper. The crimper closes to clamp the terminal; the guiding gripper closes, and the inlet pipe approaches one end of the crimper to align with the opening of the insulation sheath.

[0090] For example, the picking gripper opens, the end of the terminal passes through the opened guiding gripper, and falls into the opening of the crimper. The opening size of the crimper ensures that the end of the terminal enters. It should be noted that the opening of the crimper is surrounded by multiple crimping heads, and the crimping heads expand and contract to change the aperture of the crimper opening, which can adapt to terminals of various specifications.

[0091] For another example, the picking gripper moves downward, passes through the opened guiding gripper, sends the end of the terminal into the opened opening of the crimper, and the crimper closes to clamp the terminal; the picking gripper opens and moves away.

[0092] It should be noted that when adopting the falling-in method, a retaining ring for preventing the terminal from falling down needs to be added on the other side of the opening of the crimper, and the size of the retaining ring should be changed according to the size of the terminal. Therefore, preferably, the method of feeding the metal part of the terminal into the opened crimper by the material-taking gripper moving downward is adopted.

[0093] For another example, driven by the fifth driver, the material-taking gripper moves close to the multi-wire diameter wire terminal crimping device. After inserting the metal section of the terminal into the opening of the crimper, the material-taking gripper opens and moves away from the guiding and crimping assembly driven by the fourth driver.

[0094] When the guiding gripper is closed, in one embodiment, the accommodating part accommodates the open end of the insulating sheath of the terminal; in another embodiment, there is no accommodating part, and the guiding gripper contacts the insulating sheath on the side where the guiding tube approaches the crimper.

[0095] Step 630: The switching component moves the guiding and crimping assembly to the crimping working position.

[0096] The switching component moves the guiding and crimping assembly to the crimping working position to complete the guiding and crimping process; the switching component moves the guiding and crimping assembly back to the working position for loading the terminal, and enters the next working cycle.

[0097] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
