Description

Technical Field

[0001] This utility model relates to the field of flat wire motor technology, specifically a tooling for adjusting the length of a straight section of a flat copper wire. Background Technology

[0002] In recent years, the development of flat wire motors has accelerated, and the requirements for flat copper wire forming equipment in flat wire motors have become increasingly stringent. In the future, flat copper wire forming equipment will inevitably focus on high efficiency, high automation, and high stability as its core competitiveness. Continuous upgrades in product quality for wire forming equipment are essential. As a crucial step in wire forming, 2D bending requires improved precision. Currently, the main precision requirements for 2D forming in flat copper wire forming equipment are in the bending angle and lead length. However, inaccurate positioning of the straight segment before bending directly affects the accuracy of the lead position after bending. Therefore, there is an urgent need for a tooling device that adjusts the length of the straight segment before the 2D bending process. Utility Model Content

[0003] The purpose of this invention is to provide a tooling for adjusting the length of straight segments of flat copper wires, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a tooling for adjusting the length of a straight section of flat copper wire, including a conveyor roller, a wire length adjustment device, and a control cabinet. The conveyor roller is used to convey copper wire along a first direction. The wire length adjustment device is disposed on the side of the conveyor roller and its adjustment direction is perpendicular to the first direction. The control cabinet is electrically connected to the conveyor roller and the wire length adjustment device. The wire length adjustment device includes a gripper device, and the end of the gripper device is provided with a copper wire positioning sensor for detecting whether the copper wire is properly aligned. The control cabinet is configured to receive the detection signal from the copper wire positioning sensor and, based on the signal, control the gripper device to perform a clamping action and control the wire length adjustment device to perform a pulling action.

[0005] Furthermore, the wire length adjustment device also includes: a wire length adjustment base at the bottom, a linear drive motor fixed on the upper part of the wire length adjustment base and connected to the control cabinet, a guide rail on the side of the linear drive motor, a drive slider slidably connected on the guide rail, the drive slider being connected to the output end of the linear drive motor and powered by the linear drive motor to slide on the guide rail, and the movement direction of the drive slider being perpendicular to the conveying direction of the copper wire conveying fixture, a gripper mounting plate fixed above the drive slider, a gripper device fixed at the front end of the gripper mounting plate, the gripper device including: a gripper fixed at the front end of the gripper mounting plate, a gripper control valve above the gripper and electrically connected to the control cabinet, and a copper wire positioning sensor on the inner front end of the gripper.

[0006] Furthermore, the copper wire positioning sensor is a photoelectric sensor, with its detection end facing the clamping area of ​​the linear motor gripper.

[0007] Furthermore, two sets of line length adjustment devices are arranged parallel to each other on the side of the conveyor roller conveyor, namely a first line length adjustment device and a second line length adjustment device. The first line length adjustment device is a coarse adjustment displacement device; the second line length adjustment device is a fine adjustment displacement device.

[0008] Preferably, the adjustment distance range of the first line length adjustment device is 5mm to 50mm.

[0009] Preferably, the adjustment distance range of the second line length adjustment device is 0.5mm to 5mm.

[0010] Preferably, the conveyor roller conveyor includes: a conveyor roller conveyor base at the bottom, a conveyor synchronous belt at the top of the conveyor roller conveyor base, a conveyor roller conveyor drive motor at the end of the conveyor roller conveyor base, which is connected to the conveyor synchronous belt through a reducer, and a copper wire conveying fixture fixed on the conveyor synchronous belt.

[0011] Compared with existing technologies, the advantages of this invention are as follows: By using a linear motor to push and pull the copper wire in a straight section in a cyclical motion, the accuracy of the copper wire's position before bending is ensured, thereby achieving precise control of the wire length in 2D bending. The coarse-precision adjustment device quickly pulls the wire over a wide range to eliminate major errors, while the fine-tuning displacement device makes small-range adjustments to compensate for residual deviations, ultimately achieving the preset wire length accuracy. Then, the gripper device moves forward to push the copper wire to the contact position, and the sensor confirms the contact state in real time, completely eliminating the initial gap. Finally, the wire is precisely pulled backward to the target length, solving the problem of wire lead position offset at the root. The copper wire moves continuously on the conveyor rollers, and zero-slip conveying is achieved through the synchronous belt and tooling. The adjustment process is embedded in the production line cycle, shortening the single adjustment cycle and eliminating the need for machine stoppage. Finally, the copper wire arrival sensor detects the contact state in real time, triggering the gripper to clamp and the drive motor to avoid false clamping. The control cabinet dynamically adjusts coarse / fine adjustment parameters such as stroke and speed, and is compatible with different wire gauges. Attached Figure Description

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.

[0019] Please refer to Figure 1-5 This utility model provides a tooling for adjusting the length of a straight section of flat copper wire, including a conveyor roller 1, a wire length adjustment device 2, and a control cabinet 3. The conveyor roller 1 is used to convey copper wire 4 along a first direction. The wire length adjustment device 2 is disposed on the side of the conveyor roller 1 and its adjustment direction is perpendicular to the first direction. The control cabinet 3 is electrically connected to the conveyor roller 1 and the wire length adjustment device 2. The wire length adjustment device 2 includes a gripper device 205. The end of the gripper device 205 is provided with a copper wire positioning sensor 206 for detecting whether the copper wire 4 is in place. The control cabinet 3 is configured to receive the detection signal from the copper wire positioning sensor 206 and, based on the signal, control the gripper device 205 to perform a clamping action and control the wire length adjustment device 2 to perform a pulling action.

[0020] The system comprises a conveyor roller 1 that carries and transports copper wire tooling, establishing a basic conveyor line. A wire length adjustment device 2 is arranged perpendicular to the conveying direction, adjusting the copper wire length through lateral displacement. A control cabinet 3 coordinates the timing of the conveying and adjustment actions, achieving automated control. A gripper device 205 performs the core adjustment action, moving forward to fit the copper wire. A copper wire positioning sensor 206 detects and eliminates the gap between the gripper and the copper wire, then clamps and pulls it to the target length. The conveyor roller 1 delivers the copper wire to the workstation, the gripper 205 performs lateral movement to correct the length, and the control cabinet 3 ensures precise and synchronized actions. This system solves the problem of wire accuracy deviation after bending caused by inaccurate positioning of straight sections in traditional equipment, achieving "online adjustment without stopping the machine," thus improving production efficiency. It eliminates manual intervention and avoids secondary errors. Compared to existing technologies, where traditional solutions require offline manual adjustment or rely on complex mechanical limits, this solution significantly improves accuracy and efficiency through automated closed-loop control.

[0021] The wire length adjustment device 2 further includes: a wire length adjustment base 201 at the bottom, a linear drive motor 202 fixed on the upper part of the wire length adjustment base 201 and connected to the control cabinet 3, a guide rail on the side of the linear drive motor 202, a drive slider 203 slidably connected on the guide rail, the drive slider 203 being connected to the output end of the linear drive motor 202 and powered by the linear drive motor 202 to slide on the guide rail, and the movement direction of the drive slider 203 being perpendicular to the conveying direction of the copper wire conveying fixture 104, a gripper mounting plate 204 fixed above the drive slider 203, a gripper device 205 fixed at the front end of the gripper mounting plate 204, the gripper device 205 including: a gripper 2051 fixed at the front end of the gripper mounting plate 204, a gripper control valve 2052 above the gripper 2051 and electrically connected to the control cabinet 3, and a copper wire positioning sensor 206 on the inner front end of the gripper 2051.

[0022] The wire length adjustment base 201 provides a rigid and stable mounting platform for the linear drive motor, guide rail, and all other adjustment mechanisms, ensuring that the entire adjustment system will not deform due to vibration or force during operation and guaranteeing adjustment accuracy. The linear drive motor 202 receives instructions from the control cabinet and provides high-precision linear reciprocating motion. The drive slider 203 converts the rotational motion of the linear drive motor into precise linear motion. The guide rail ensures that the drive slider and all its components move at high speed, smoothly, and with low friction along a strictly linear trajectory. The gripper mounting plate 204 carries the grippers, and the gripper device 205 is responsible for directly gripping and manipulating the copper wire. In the open state, it extends forward to push the copper wire against the reference surface, eliminating all initial gaps. After clamping the copper wire, it moves with the entire drive slider, performing a precise pulling action. The copper wire positioning sensor 206 is installed on the inner front end of the gripper to detect in real time, non-contactly, whether the copper wire has entered the workstation and whether it has been pushed to the preset reference position.

[0023] The copper wire positioning sensor 206 is a photoelectric sensor, and its detection end faces the clamping area of ​​the linear motor gripper 2051.

[0024] Two sets of line length adjustment devices 2 are arranged parallel to each other on the side of the conveyor roller 1, namely a first line length adjustment device 211 and a second line length adjustment device 212. The first line length adjustment device 211 is a coarse adjustment displacement device; the second line length adjustment device 212 is a fine adjustment displacement device.

[0025] The adjustment distance range of the first line length adjustment device 211 is 5mm to 50mm.

[0026] The adjustment distance range of the second line length adjustment device 212 is 0.5mm to 5mm.

[0027] The conveyor roller conveyor 1 includes: a conveyor roller conveyor base 101 at the bottom, a conveyor synchronous belt 102 at the top of the conveyor roller conveyor base 101, a conveyor roller conveyor drive motor 103 at the end of the conveyor roller conveyor base 101, which is connected to the conveyor synchronous belt 102 through a reducer, and a copper wire conveying fixture 104 fixed on the conveyor synchronous belt 102.

[0028] The conveyor roller base 101 provides rigid support to ensure operational stability, while the synchronous conveyor belt 102 provides high-precision transmission to prevent copper wire slippage. The conveyor roller drive motor 103 controls the belt speed through a reducer to achieve uniform conveying. The copper wire conveying fixture 104 is customized to fix the copper wire and prevent displacement. Zero relative slippage during the conveying process ensures the initial positioning accuracy of the copper wire and provides a stable benchmark for subsequent length adjustments.

[0029] Example 1: Example of a single line length adjustment device

[0030] This embodiment provides a compact adjustment fixture suitable for production scenarios with high precision requirements but relatively stable adjustment range. The fixture includes a conveyor roller conveyor 1, a wire length adjustment device 2, and a control cabinet 3. The wire length adjustment device 2 is positioned perpendicular to the conveying direction on one side of the roller conveyor, and its structure is consistent with the description in the claims, including a wire length adjustment base 201, a linear drive motor 202, a guide rail, a drive slider 203, a gripper mounting plate 204, and a gripper device 205. Crucially, the end of the gripper device 205 integrates a copper wire positioning sensor 206. The workflow and principle of this embodiment are as follows: a flat copper wire 4 is placed on the copper wire conveying fixture 104; the conveyor roller conveyor drive motor 103 starts, and the copper wire is conveyed at a uniform speed to a single wire length adjustment station via a synchronous belt 102. When the copper wire enters the station, the copper wire positioning sensor 206 detects its presence and sends a signal to the control cabinet 3. Control cabinet 3 instructs gripper 2051 to open and starts linear drive motor 202 to push the gripper forward until the copper wire is pushed against the preset mechanical reference position. Sensor 206 monitors in real time to confirm that the copper wire is fully adhered. After receiving the adhesion confirmation signal, control cabinet 3 immediately instructs gripper 2051 to close and clamp the copper wire. Subsequently, linear drive motor 202 moves in the opposite direction, pulling the copper wire backward to the target length at a single speed and with a preset precise stroke. After adjustment, the gripper opens, and linear drive motor 202 drives the gripper device back to the initial position. Conveyor roller 1 starts to send the adjusted copper wire away, and the entire process is complete.

[0031] Example 2: Example of a dual-line length adjustment device

[0032] This embodiment provides an ultra-high precision and high efficiency adjustment fixture suitable for production scenarios with large fluctuations in incoming material errors or products requiring extremely high precision. The core improvement of this fixture, based on Embodiment 1, lies in the parallel arrangement of two independent line length adjustment devices on the same side of the conveyor roller conveyor 1. These are the first line length adjustment device 211 (coarse adjustment device) and the second line length adjustment device 212. The two devices are mechanically identical, both including sensors, grippers, linear motors, etc. However, their process parameters differ in the program settings of control cabinet 3. The initial feeding and conveying process is the same as in Example 1, except that the copper wire is first conveyed to the first wire length adjustment device 211. The first copper wire arrival sensor detects a signal, triggering the coarse adjustment process. The coarse adjustment gripper performs a "push-clamp" action. Subsequently, the first linear drive motor drives the gripper with high power and high speed to pull it backward quickly with a large stroke, rapidly eliminating 80%-90% of the length error. After completion, the coarse adjustment gripper is released and reset. The conveyor roller immediately sends the coarse-adjusted copper wire to the downstream second wire length adjustment device 212. The second copper wire arrival sensor detects a signal, triggering the fine adjustment process. The fine adjustment gripper performs a "push-clamp" action. Subsequently, the second linear drive motor drives the gripper with high precision and low speed to perform slow micro-movements with a small stroke, accurately compensating for the remaining 10%-20% residual deviation after coarse adjustment. After completion, the fine-tuning jaws are released and reset. After two stages of adjustment, the copper wire length has reached the preset ultra-high precision requirement. Finally, it is sent to the downstream bending process by the conveyor roller.

Based on the embodiments of the present invention, it will be understood by those skilled in the art that all other embodiments obtained by making various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention and without creative effort are within the scope of protection of the present invention.
