Description

Technical Field

[0001] This utility model relates to the field of processing equipment, specifically a pre-straightening structure for copper wire. Background Technology

[0002] In the manufacture of precision components such as copper probes and electronic component leads, wound copper wires are commonly used as raw materials. After unwinding, these wires often exhibit varying degrees of bending, kinking, or internal stress. If they are not straightened, they will directly lead to serious problems in subsequent processing stages.

[0003] For example, when entering precision cutting or stamping dies, bent wire is prone to jamming and inaccurate feeding, causing frequent equipment downtime or even die damage. During end forming (such as riveting or gold plating) or assembly, non-straight wire leads to large dimensional variations and poor product consistency, severely reducing yield. Furthermore, for probe-type products requiring high-precision length control, the wire's inherent bending directly results in inconsistent cut product lengths, failing to meet stringent dimensional tolerance requirements.

[0004] While existing straightening institutions can play a certain role in straightening, they generally suffer from problems such as an unintuitive adjustment process and inconsistent straightening results. Furthermore, the lack of effective online quality monitoring during the straightening process means that insufficiently straightened or failed straightening wires are usually only discovered in subsequent processes, resulting in a waste of materials and time.

[0005] Therefore, there is an urgent need for a pre-calibration structure that can stably pre-calibrate and provide real-time quality feedback to ensure production continuity and product reliability. Utility Model Content

[0006] The purpose of this invention is to provide a pre-straightening structure for copper wire. Through a sequentially arranged lubrication unit, adjustment assembly, detection component, and conveyor seat, it optimizes the entire process of straightening copper wire, from lubrication and high-speed rotation straightening to online detection and visible conveying. It provides sufficient and uniform lubrication to the wire, reducing friction loss; the movable seat and flexible sleeve of the adjustment assembly effectively straighten the wire through high-speed rotation, facilitating real-time monitoring of the straightening process and wire condition; simultaneously, it can promptly detect unstraightened wire and trigger an alarm, preventing defective products from flowing into the next process; overall, it improves the reliability, production efficiency, and product quality of the straightening process.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A pre-straightening structure for copper wire includes a lubrication unit, an adjustment component, a detection element, and a conveyor seat arranged sequentially along the wire's travel direction. The lubrication unit has a through hole through which the wire can pass, and an adsorbent for adsorbing and releasing lubricant is provided inside the lubrication unit. The adjustment component includes a front fixed base, a rear fixed base, and a movable seat located in the middle. The movable seat can rotate at high speed, and a flexible sleeve for the wire to pass through is provided in the middle of the movable seat. The movable seat also has an observation grid. The detection element is used to detect the position of the wire and trigger a signal when the wire position is abnormal. The middle of the conveyor seat is empty, allowing the wire to travel in the air and be visible.

[0008] Compared with existing technologies, the pre-straightening structure of copper wire using the above-mentioned technical solution has the following advantages: By modularly arranging four functional units—lubrication, straightening, inspection, and visual conveying—a complete pre-straightening solution is constructed, ensuring the smoothness, effectiveness, quality control, and visibility of wire processing. Specifically, the lubrication unit provides sufficient and uniform lubrication to the wire, reducing friction loss and copper dust generation; the adjusting assembly's movable seat and flexible sleeve effectively straighten the wire through high-speed rotation, with observation grids facilitating real-time monitoring of the straightening process and wire status; the inspection unit instantly detects unstraightened wire and triggers alarms, preventing defective products from flowing into the next process; and the centrally elevated conveyor ensures full visibility of the wire's path, facilitating manual sampling and status confirmation, thereby comprehensively improving the equipment's automation level and production yield.

[0009] Preferably, the adsorbent has a ring-shaped structure, with a visible hole in the center for observing the condition of the wire. The lubrication unit is equipped with an oil storage chamber communicating with the adsorbent and an openable / closable filling pipe. The design of the adsorbent combined with the oil storage chamber and filling pipe enables the replenishment of lubricating oil and the release of oil during long-term use, ensuring the long-term uniformity and stability of wire lubrication, reducing the workload of frequent manual lubrication. The visible hole in the center of the ring-shaped adsorbent facilitates observation of the lubrication status and the surface condition of the wire.

[0010] Preferably, the adsorbent is made of a porous adsorbent material, including but not limited to sponges and non-woven fabrics. Using porous adsorbent materials such as sponges or non-woven fabrics is cost-effective and provides excellent oil storage and release performance. It can gently coat the surface of the wire, preventing lubricant dripping, and the material is easy to replace and maintain.

[0011] Preferably, the lubrication unit has a positioning part in the center that matches the diameter of the viewing hole. The height of the positioning part does not exceed the height of the adsorbent. When the wire passes through the adsorbent, the wire does not contact the positioning part. The positioning part effectively restricts the left and right movement of the adsorbent in the lubrication unit without contacting the wire, thus ensuring the lubrication effect and avoiding possible scratches or blockages to the wire caused by the displacement of the adsorbent.

[0012] Preferably, the flexible sleeve is made of a transparent or semi-transparent material, and a lubrication gap exists between the inner wall of the flexible sleeve and the wire. The use of a transparent or semi-transparent material and the presence of a lubrication gap allow operators to directly observe the internal operating state of the wire during high-speed straightening, while the lubricating oil within the gap further reduces friction and protects the wire surface.

[0013] Preferably, the detection element is a ring conductor, which is electrically connected to a control unit. When the wire deviates from the preset axis due to lack of straightening and comes into contact with the ring conductor, the electrical signal received by the control unit changes, thereby triggering an alarm or sending a signal to the worker's terminal. By using the ring conductor and the control unit to form a contact-type electrical detection circuit, it can instantly respond to the wire's offset contact signal, realizing real-time, automated online monitoring of straightening quality, timely interception of defective products, and effective prevention of subsequent processing failures.

[0014] Preferably, the movable seat achieves high-speed rotation via a drive mechanism. The drive mechanism includes a drive rod, a drive belt, a drive shaft, and a drive motor. The drive rod is movably mounted on both the front and rear fixed bases and is connected to the movable seat. The drive shaft is located on either the side of the front fixed base away from the movable seat or the side of the rear fixed base away from the movable seat. The drive rod is connected to the drive shaft. The drive motor is located below the adjustment assembly, and its output drives the drive shaft to rotate via the drive belt. This transmission method, where the drive motor transmits power to the movable seat via the drive belt, drive shaft, and drive rod, results in a compact structure, smooth transmission, and a stable and reliable power source for the high-speed rotation of the movable seat, ensuring uniform straightening results.

[0015] Preferably, the conveyor base includes a support, a conveying section, and an electronically controlled drive module. The support is equipped with a guide rail, and the conveying section is movably mounted on the guide rail. The electronically controlled drive module drives the conveying section to reciprocate on the guide rail to move the wire. The reciprocating motion of the conveying section on the guide rail is precisely controlled by the electronically controlled drive module, achieving precise control of the wire conveying step length and speed, and providing stable and reliable feeding conditions for subsequent processing steps.

[0016] Preferably, the middle of the conveying section and the middle of the support are equipped with observation slots for viewing the wire condition, making the wire routing visible. The design of the observation slots ensures that the wire is fully exposed during the conveying process, providing operators with an unobstructed visual inspection window throughout the entire process. This facilitates the rapid detection of surface defects or bending problems in the wire, enabling real-time quality monitoring during production.

[0017] Preferably, the observation grid is a rectangular window, a circular hole, or a grid structure that runs through the movable base. Specifying the observation grid as a rectangular window, a circular hole, or a grid structure provides a variety of feasible implementation schemes, maximizing the field of view while ensuring the structural strength of the movable base, and meeting the observation needs in different scenarios.

[0024] The present invention will now be further described with reference to the accompanying drawings.

[0025] like Figures 1 to 5 The pre-straightening structure for copper wire shown includes a lubrication unit 1, an adjustment component 2, a detection component, and a conveyor seat 3 arranged sequentially along the wire's travel direction 0.

[0026] The lubrication unit 1 is provided with a through hole 10 through which the wire 0 can pass, and the lubrication unit 1 is provided with an adsorbent 11 for adsorbing and releasing lubricant.

[0027] Considering the need to check the condition of the wire 0 and the lubrication requirements for long-term operation of the equipment, in this embodiment, the adsorption body 11 is a ring structure, and the middle part of the adsorption body 11 is a viewing hole 12 for observing the condition of the wire 0. The lubrication unit 1 is provided with an oil storage chamber 13 communicating with the adsorption body 11 and an openable and closable filling pipe 14.

[0028] The filling pipe 14 and the oil storage chamber 13 are located here. The filling pipe 14 can be opened and closed by machine or manual clamping, and is used for machine injection of lubricating oil or manual injection of lubricating oil.

[0029] To facilitate the smooth passage of the wire 0 and simultaneously meet lubrication requirements, the adsorbent 11 is made of porous adsorbent material, including but not limited to sponge and non-woven fabric.

[0030] To simultaneously satisfy the requirements of observing the passage of wire 0 and limiting the position of the lower adsorbent 11 in the lubrication unit 1, a positioning part 15 adapted to the diameter of the viewing hole 12 is provided in the middle of the lubrication unit 1. The height of the positioning part 15 does not exceed the height of the adsorbent 11. When the wire 0 passes through the adsorbent 11, the wire 0 does not contact the positioning part 15.

[0031] The adjustment assembly 2 includes a front fixed base 20, a rear fixed base 21, and a movable base 22 located in the middle. The movable base 22 can rotate at high speed. The movable base 22 has a flexible sleeve 23 in the middle for the wire 0 to pass through, and the movable base 22 is provided with an observation grid 24.

[0032] To further clarify the straightening or passing status of the wire 0, the flexible sleeve 23 is made of transparent or semi-transparent material, and there is a lubrication gap between the inner wall of the flexible sleeve 23 and the wire 0.

[0033] The detection device is used to detect the position of wire 0 and trigger a signal when the position of wire 0 is abnormal. The middle part of the conveyor seat 3 is empty, so that the wire 0 can be seen running in the air.

[0034] Regarding the detection component, in this embodiment, the detection component is a ring conductor 4, which is electrically connected to a control unit. When the wire 0 deviates from the preset axis due to lack of straightening and comes into contact with the ring conductor 4, the electrical signal received by the control unit changes, thereby triggering an alarm or sending a signal to the worker's terminal. The control unit can refer to existing factory equipment object offset signal detection devices, or the contact detection signal triggering mechanism of CN114122851B, or the electrical characteristic change judgment scheme of CN110660779B.

[0035] The movable seat 22 achieves high-speed rotation through the drive mechanism 5, which includes a drive rod 50, a drive belt 51, a drive shaft 52, and a drive motor 53.

[0036] The drive rod 50 is movably mounted on both the front fixed base 20 and the rear fixed base 21, and is connected to the movable seat 22. The drive shaft 52 is located on the side of the front fixed base 20 away from the movable seat 22 or on the side of the rear fixed base 21 away from the movable seat 22. The drive rod 50 is connected to the drive shaft 52. The drive motor 53 is located below the adjustment assembly 2, and the output end of the drive motor 53 drives the drive shaft 52 to rotate via the drive belt 51.

[0037] Regarding the transmission method of wire 0 by the conveyor 3, in this embodiment, the conveyor 3 includes a bracket 30, a conveying part 31, and an electronically controlled drive module 32. The bracket 30 is provided with a guide rail 33, and the conveying part 31 is movably mounted on the guide rail 33. The electronically controlled drive module 32 drives the conveying part 31 to move back and forth on the guide rail 33 to move the wire 0. The electronically controlled drive module 32 can refer to the wire conveying equipment in a copper product processing plant, or refer to the translation drive mechanism 5 of CN212305057U, or the combination of the module drive assembly and the guide rail 33 of CN120003920A.

[0038] In addition, the middle part of the conveying section 31 and the middle part of the bracket 30 are observation slots 6 for viewing the status of the wire 0, so that the wire 0 can be seen running in the air.

[0039] Furthermore, the observation grid 24 in this case is a rectangular window, a circular hole, or a grid structure that passes through the movable seat 22. In this embodiment, there are multiple observation grids 24, and the observation grid 24 in this embodiment adopts a rectangular window style.

[0040] During use, the unwound wire 0 is first fed into the structure using existing unwinding equipment. The specific operation sequence is as follows: Wire 0 first enters the through hole 10 of the lubrication unit 1, where the annular adsorption body 11 evenly applies oil to lubricate the surface of wire 0; after lubrication, wire 0 enters the adjustment assembly 2 and passes through the flexible sleeve 23 in the middle of the movable seat 22. During this process, the drive motor 53 drives the movable seat 22 to rotate at high speed via the drive belt 51, drive shaft 52, and drive rod 50, straightening the wire 0 using the high-speed twisting principle. The operator can observe the straightening process in real time through the observation grid 24; after straightening, wire 0 continues to move forward. If the wire 0 deviates and contacts the annular conductor 4 due to insufficient straightening, the control unit will receive a change in electrical signal and trigger the equipment to pause or send an alarm message to the worker's terminal. Finally, the wire 0 is sent into the conveyor seat 3. The electric control drive module 32 drives the conveyor section 31 to reciprocate along the guide rail 33, thereby clamping and pulling the wire 0 to be conveyed step by step to the subsequent processing structure. During the entire conveying process, the wire 0 is always exposed in the observation slot 6, keeping it in a visible state for easy visual inspection.

[0041] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
