Description

Technical Field

[0001] This invention relates to a device for threading electrical components, specifically an automatic threading device for threading electrical components. Background Technology

[0002] Currently, many electrical components require the installation of corresponding wires (conductive wires or signal wires) into their housings during the manufacturing process. For example, temperature sensors require the temperature sensing wire to be threaded into the sensor's housing, and then manually or using relevant equipment to connect the wire to the electrical component housed within the sensor's housing.

[0003] Traditionally, wiring involves manually holding one end of the wire and inserting it into the connection hole (wiring hole) of the electrical component's housing. Then, a wire clamp is used to clamp the wire end and pull a portion of the wire outside the housing, completing the wiring installation. This method relies entirely on manual operation, resulting in extremely low wiring efficiency and unpredictable results, failing to meet the requirements of modern manufacturing. Furthermore, with rising labor costs, the cost of relying solely on manual wiring is also increasing.

[0004] To improve the efficiency of wire threading for electrical components, reduce threading costs, and enhance threading accuracy, mechanical equipment for automated or semi-automated wire threading of electrical components has been developed and put into use. However, existing automated wire threading equipment for electrical components has not been effectively promoted. The main reasons for this are: most of the wires used in existing electrical components, whether conductive or signal wires, are flexible materials, making them prone to bending, misalignment, or deformation at the insertion end during threading; in addition, the position and diameter of the threading holes on the casing of electrical components generally require high precision. Therefore, automated threading is extremely difficult to achieve when bending, misalignment, or deformation occurs at the clamping end of the wire.

[0005] Therefore, the research objective of this invention is to develop an automatic wire threading device for electrical components that can effectively and stably clamp the plug-in end of the wire and prevent excessive bending, misalignment or deformation of the wire during the threading process, thereby effectively and quickly and accurately inserting the plug-in end of the wire into the threading hole of the corresponding product housing. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic threading device for electrical component threading, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automatic wire threading device for electrical component threading includes

[0009] A wire supply device includes a movable frame, which is driven by a corresponding movable frame drive mechanism, and a wire clamping feeder is fixed on the movable frame.

[0010] A threading device includes a fixed frame and a guide plate on the fixed frame that can be raised and lowered. A wire-taking claw corresponding to the wire-feeding claw is raised and lowered on the guide plate below the wire-taking claw. A threading claw is raised and lowered on the guide plate below the wire-taking claw. Corresponding clamping elements are fixedly installed on the claws of the threading claw. A slot corresponding to the wire is provided on the opposite side of the clamping element. A corresponding guide plate is installed on the clamping element below the slot. When the threading claw clamps, the slot of the clamping element clamps the wire, and the inner sidewall of the guide plate abuts against the outer side of the wire.

[0011] The mounting platform is used to fix and place the workpiece. The mounting platform is located on the lower side of the wire-feeding clamp. The mounting platform is provided with a connecting hole for the wire to pass through at the position where the workpiece is placed.

[0012] The wire pulling device includes a support frame disposed on the lower side of the mounting platform, and the support frame is equipped with wire pulling claws for clamping the wire.

[0013] It also includes a threading guide, on which a corresponding guide bracket is movably installed. The threading guide includes guide jaws that are liftably installed on the guide bracket. Corresponding guide components are fixedly installed on the jaws of the guide jaws. Corresponding threading grooves are provided on opposite sides of the guide components. When the guide jaws clamp, the threading grooves of the guide components close to form a guide channel for the guide plate and the wire to pass through.

[0014] The guide gripper is mounted on the guide bracket by a corresponding guide gripper drive cylinder. The wire guide groove includes a first guide portion corresponding to the guide plate and a second guide portion corresponding to the wire. The first guide portion is horizontally disposed on the top of the guide member, and the second guide portion is vertically disposed on the inner side of the guide member. The top ends of the second guide portions are respectively connected to the inner ends of the corresponding first guide portions. The connection between the second guide portion and the first guide portion is provided with corresponding guide chamfers in a beveled shape.

[0015] A wire feeding and straightening clamp is fixed on the movable frame below the wire feeding clamp. The inner side of the claw of the wire feeding and straightening clamp is provided with a corresponding first guide groove. When the wire feeding and straightening clamp is clamped, the first guide groove closes to form a wire feeding and straightening hole with a diameter greater than the maximum width of the wire. An interval space is formed between the wire feeding clamp and the wire feeding and straightening clamp to allow the wire taking clamp to pass through. The distance between the open claws of the wire feeding clamp is greater than the width of the closed claws of the wire taking clamp.

[0016] The fixed frame is provided with a set of guide plate mounting rails. The guide plate can be lifted and lowered on the guide plate mounting rails and is driven to rise and fall by a guide plate drive cylinder fixed on the fixed frame.

[0017] The wire-taking clamp is fixed on the corresponding wire-taking mounting plate, and the wire-taking mounting plate is movably mounted on the drive rail of the guide plate; a wire-taking drive screw for driving the wire-taking mounting plate is rotatably mounted on the guide plate, and a first fixed guide sleeve is fixedly connected to the wire-taking drive screw by a threaded connection on the back side of the wire-taking mounting plate; the wire-taking drive screw is driven by a corresponding wire-taking drive motor.

[0018] The threading clamp is fixed on the corresponding threading mounting plate. The threading mounting plate is movably mounted on the drive rail of the guide plate and is driven by the threading drive cylinder fixed on the guide plate.

[0019] The support frame is fixed with a support frame mounting rail, and a pull wire clamp mounting plate is movably mounted on the support frame mounting rail. The pull wire clamp is fixed on the pull wire clamp mounting plate. A corresponding pull wire straightening clamp is fixed on the upper or lower side of the pull wire clamp mounting plate. The inner side of the claw of the pull wire straightening clamp is provided with a corresponding second guide groove. The second guide groove closes to form a pull wire straightening hole with a diameter greater than the maximum width of the wire.

[0020] One claw of the wire pulling and straightening clamp has a clearance groove that connects to the second guide groove, and the other claw of the wire pulling and straightening clamp has a mounting hole that connects to the second guide groove. A longitudinally arranged piercing blade is telescopically mounted on the mounting hole. The piercing blade is telescopically driven by a corresponding piercing blade drive cylinder. When the piercing blade extends into the clearance groove, the wire located in the wire pulling and straightening hole is pierced by the piercing blade.

[0021] The support frame is rotatably mounted with a corresponding wire pull drive screw on one side without the support frame mounting rail. The back side of the wire pull claw mounting plate is fixedly connected to a second fixed guide sleeve that is threadedly connected to the wire pull drive screw. The wire pull drive screw is driven by a corresponding wire pull drive motor.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1) The threading clamp of the present invention has corresponding clamping members fixedly installed on the claws. Each clamping member has a corresponding slot on its opposite side, and a corresponding guide plate is installed on the clamping member below the slot. During threading, the clamping of the threading clamp effectively directionally clamps the wire using the slots of the clamping members. After clamping, the inner sidewalls of the guide plates abut against the outer side of the wire to provide anti-deviation support for the insertion end of the wire.

[0024] With the directional clamping of the clamping component equipped with a slot, sufficient preload is effectively ensured for the wire during insertion. Furthermore, the intervention of the guide plate effectively provides anti-deviation support for the wire located below the clamping component, i.e., the insertion end of the wire, thus precisely guiding the insertion end of the wire to the threading hole of the corresponding product housing. This effectively and stably clamps the insertion end of the wire and prevents excessive bending, misalignment, or deformation of the wire during insertion, thereby automatically and quickly and accurately inserting the insertion end of the wire into the threading hole of the corresponding product housing.

[0025] 2) The present invention is provided with a wire pulling device. After the wire pulling jaws partially pass the wire through the wire hole of the workpiece (shell), the wire pulling jaws can clamp the insertion end of the wire and pull it down, so as to greatly reduce the insertion length of the wire by the wire pulling jaws, thereby significantly improving the overall wire pulling speed of the present invention.

[0026] 3) The present invention also includes a threading guide, which includes a guide jaw that can be raised and lowered. The jaws of the guide jaws are respectively fixed with corresponding guide members. The opposite side of the guide members is respectively provided with corresponding threading guide grooves. When the guide jaws are clamped, the threading guide grooves of the guide members close to form a guide channel for the guide plate and the wire to pass through.

[0027] The second guide portion of the threading guide groove closes to form a guide hole that matches the threading hole of the workpiece (housing), while the first guide portion of the threading guide groove combines to form a transverse guide groove that communicates with the guide hole. During the threading process, when the guide piece is inserted into the transverse guide groove formed by the first guide portion combination, the insertion end of the wire is oriented to the top of the guide hole formed by the second guide portion combination. Then, the threading jaws open and rise a short distance. During this process, the guide piece moves laterally and upward within the transverse guide groove formed by the first guide portion combination. This threading action of clamping and descending is then repeated cyclically until the insertion end of the wire gradually moves down along the guide hole formed by the second guide portion closing and passes through the threading hole of the workpiece (housing). Before each downward movement of the threading jaws, the take-up jaws descend synchronously by the same distance to ensure sufficient wire supply. Thus, with the combined action of the wire guide, clamp, and guide plate, the wire insertion end is effectively and quickly and accurately inserted into the wire hole of the corresponding product housing in a progressive manner.

[0028] Under the action of the wire guide, the height of the wire-threading hole of the workpiece (shell) is raised to the upper part of the workpiece. In this way, it can effectively cooperate with the clamping part with the guide plate, so as to greatly improve the convenience, feasibility and accuracy of the automated wire threading. Most importantly, under the action of the transverse guide groove formed by the first guide part combination, the guide plate can always be located on the top periphery of the guide hole formed by the second guide part closing during the repeated action to progressively thread the wire. This ensures that the guide plate can accurately abut against the outside of the wire after closing again, thereby effectively ensuring the practical effect of the invention.

[0029] 4) The moving frame on the lower side of the wire supply clamp of the present invention has a wire supply and winding clamp. The inner side of the claw of the wire supply and winding clamp is respectively provided with a corresponding first guide groove. When the wire supply and winding clamp is clamped, the first guide groove closes to form a wire supply and winding hole with a diameter greater than the maximum width of the wire. A space is formed between the wire supply clamp and the wire supply and winding clamp to allow the wire take-up clamp to pass through. The distance between the opening of the claw of the wire supply clamp is greater than the width of the claw of the take-up clamp when it is closed.

[0030] During the wire feeding process, the wire feeding jaws clamp the upper end of the wire, while the wire feeding straightening jaws limit and fix the wire below the wire feeding jaws. Driven by the moving frame drive mechanism, the moving frame moves the wire feeding jaws and wire feeding straightening jaws to move and fix the wire between the jaws of the wire taking jaws. Then, the wire taking jaws clamp the wire, and then the wire feeding jaws release. The guide plate then rises to drive the wire taking jaws to rise, thereby driving the wire to rise. Under the action of the wire feeding straightening hole, the wire is straightened during the rising process. After the wire taking jaws rise to the correct position, the wire threading jaws are located at the position corresponding to the lower end of the wire. At this time, the wire threading jaws move to fix the lower end of the wire to facilitate the subsequent wire threading action. Therefore, with the intervention of the wire feeding and straightening clamps and the improved design of their installation method, they can effectively cooperate with components such as the wire taking clamps to perform a full, reasonable and convenient straightening action on the wire before threading. This can effectively ensure that the wire does not tangle during the threading process and ensure the tension of the wire during the threading process, thereby further improving the practical effect of the present invention.

[0031] 5) Under the action of the pull-wire clamp that can be raised and lowered, the pull-wire straightening clamp of the present invention is further raised and lowered, and the inner side of the clamp is provided with a corresponding second guide groove. The second guide groove is closed to form a pull-wire straightening hole with a diameter greater than the maximum width of the wire.

[0032] During the wire pulling process, the wire pulling jaws are activated to clamp the lower end of the wire, and then the wire pulling jaw mounting plate moves downward to pull the wire into place. Afterward, the wire pulling jaw mounting plate resets, and the wire pulling and straightening jaws are activated so that the second guide grooves on their jaws close around the periphery of the wire. Then, the wire pulling jaw mounting plate moves downward again to straighten the wire located at the bottom of the workpiece (shell), thereby effectively ensuring that the wire does not tangle or cause other problems after being threaded into place.

[0033] 6) One claw of the wire pulling and straightening clamp of the present invention is provided with a relief groove communicating with its second guide groove, and the other claw of the wire pulling and straightening clamp is provided with a mounting hole communicating with its second guide groove. A longitudinally arranged piercing blade is telescopically mounted on the mounting hole. The piercing blade is telescopically driven by a corresponding piercing blade driving cylinder. When the piercing blade extends into the relief groove, the wire located in the wire pulling and straightening hole is pierced by the piercing blade.

[0034] In this way, wire splitting can be selectively performed simultaneously during the wire straightening process, thereby effectively increasing the practical effect of the invention without increasing labor time. This is because existing electrical component wires, whether conductive or signal wires, mostly consist of two sub-wires, and the two sub-wires often need to be separated after threading due to installation requirements. Current methods mostly involve manually cutting or tearing them apart, which is cumbersome and labor-intensive. The improved wire straightening clamp of this invention not only enables wire straightening but also allows the piercing blade to be retractably installed and used for wire splitting, thus effectively enhancing the practical effect of the invention.

The pull wire drive screw 21 is driven by a corresponding pull wire drive motor 23.

[0068] The method of using the automatic threading equipment for electrical component threading described above includes the following specific steps:

[0069] S1. The workpiece 4 is fixedly placed on the installation platform 3 by manual or mechanical feeding. The guide gripper drive cylinder 603 rises, and then the guide drive cylinder 701 drives the guide bracket 7 to move outward. After moving outward, the guide gripper 601 clamps, and then the guide gripper drive cylinder 603 retracts, so that the wire guide groove 6021 of the guide member 602 of the wire guide 6 closes to form a guide channel for the guide plate 2052 and the wire to pass through, and the bottom surface of the guide member 602 contacts the upper surface of the workpiece 4.

[0070] S2, the moving frame drive mechanism is activated to move the moving frame 101 horizontally outward. The upper end of the wire is moved to the position of the wire feeding claw 102 and the wire feeding and straightening claw 103 by manual or mechanical feeding. Then, the wire feeding claw 102 and the wire feeding and straightening claw 103 operate respectively to clamp and limit the upper end of the wire.

[0071] S3, the moving frame drive mechanism is restarted to drive the moving frame 101 to reset, and the wire is fixedly clamped and moved between the claws of the wire taking claw 203 by the wire supply clamp 102 and the wire supply and winding clamp 103.

[0072] S4, the wire take-up clamp 203 starts to clamp the wire, and then the wire supply clamp 102 releases. Then the guide plate 202 rises to drive the wire take-up clamp 203 to rise, thereby driving the wire to rise. During this process, the wire supply straightening hole can straighten the wire during the rising process.

[0073] S5, after the wire-picking claw 203 rises to the position, the moving frame drive mechanism is activated to drive the moving frame 101 downward. Then, the wire-threading claw 204 moves to drive the clamping member 205 to clamp and fix the lower end of the wire. Then the wire-straightening claw 103 opens, and at the same time, the moving frame drive mechanism is activated again to move the moving frame 101 horizontally outward and drive the moving frame 101 upward to reset, so as to feed the wire again.

[0074] S6, the threading jaw 204 moves down to the guide plate 2052 and enters the first guide part 60211 of the threading guide groove 6021. Then, the threading jaw 204 opens and rises a short distance (3mm). Then, the clamping and descending action is repeated in a cycle, so that the bottom end of the wire continuously enters the second guide part 60212 of the threading guide groove 6021 in a progressive manner, and finally passes through the threading hole of the workpiece 4. During this process, before each descent of the threading jaw 204, the wire taking jaw 203 descends synchronously by the same distance.

[0075] S7, the wire clamp 502 starts to clamp the wire passing through the workpiece and the mounting platform 3, then the wire clamp mounting plate 18 moves down to pull the wire into place, and then the wire clamp 502 opens.

[0076] S8, the wire pulling jaw mounting plate 18 moves up to the corresponding position, and then the wire pulling and straightening jaw 503 is activated so that the second guide groove 5031 on its jaws closes the periphery of the wire. Then the wire pulling jaw mounting plate 18 moves down again to straighten the wire located at the lower part of the workpiece 4. During this process, the piercing blade drive cylinder 20 can be selectively controlled to extend, so as to drive the piercing blade 19 to extend into the relief groove 5032, thereby piercing the wire located in the wire pulling and straightening hole, so as to selectively perform wire splitting processing on the wire during the straightening operation.

[0077] Example 2:

[0078] Please refer to Figure 14-15 The difference between this embodiment and embodiment one is that the wire pulling and straightening clamp (503) is fixed on the lower side of the wire pulling clamp (502), and the wire pulling clamp mounting plate (18) on the lower side of the wire pulling and straightening clamp (503) is also fixed with a wire cutting clamp (24). A corresponding guide hole is provided in the middle of one of the claws of the wire cutting clamp (24). A horizontally arranged cutting blade (25) is telescopically installed in the guide hole. The cutting blade (25) is telescopically driven by the corresponding cutting blade driving cylinder (26). When the cutting blade (25) extends, the wire between the claws of the wire cutting clamp (24) is cut by the cutting blade (25).

[0079] The wire pulling, straightening, and separating processes in this embodiment are the same as in Embodiment 1, with the optional addition of a wire cutting function. The wire cutting process is as follows: the wire cutting jaws (24) are activated to clamp the wire; then, the wire pulling jaw mounting plate 18 moves down to drive the wire cutting jaws (24) to the cutting position where the cutting blade 25 is facing the wire; then, the cutting blade drive cylinder 26 is controlled to extend, so that the cutting blade 25 extends to horizontally cut the wire. After the wire is cut, the wire cutting jaws (24) open, and the wire pulling jaw mounting plate 18 returns to its original position, thereby effectively increasing the functionality of the invention.

[0080] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
