Description

Technical Field

[0001] The utility model relates to the technical field of copper wire stretching, in particular to a feeding and stretching device for bonding copper wire. Background Technique

[0002] Bonding copper wire is a slender metal wire made of metal copper as raw material through specific processing technology. It has a wide range of applications in the electronics industry, mainly because it has good electrical conductivity and ductility. In practical applications, bonding copper wire is usually used as a wire on a circuit board to connect different electronic components. Due to its small diameter, it can form a compact layout on the circuit board, thereby improving the reliability and performance of the circuit. In addition, bonding copper wire can also be used to manufacture electrodes, transmission lines and other conductive components in electronic devices.

[0003] In the current production process of bonding copper wire, the existing equipment cannot monitor the stress state of the copper wire in real time, which increases the risk of copper wire breakage during the stretching process. The breakage of the copper wire will not only cause production interruption and reduce production efficiency, but may also affect the quality of the whole batch of products, because the broken copper wire cannot guarantee its ductility and dimensional accuracy. In addition, due to the difficulty of controlling the stretching force, the stretching degree of the copper wire may be uneven. Summary of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 5 , in the embodiment of the present invention, a feeding and stretching device for bonding copper wire includes a first support 1. A second support 2 is arranged on the right side of the first support 1. A regulation mechanism 3 is arranged in the middle of the first support 1 and the second support 2. A monitoring mechanism 4 is arranged above the second support 2. The regulation mechanism 3 includes a support rod 301, a hydraulic push rod 302, a mounting plate 303 and a limit disc 307. A support rod 301 is fixedly installed in the middle of the first support 1 and the second support 2. The upper end of the support rod 301 is fixedly installed with a hydraulic push rod 302. The transmission end of the hydraulic push rod 302 is fixedly installed with a mounting plate 303. Four groups of limit discs 307 are arranged above the mounting plate 303. A copper wire body 5 is arranged in the middle of the four groups of limit discs 307. The regulation mechanism 3 further includes a strut 304, a rod seat 305, a bearing ring 306, a first bearing bracket 308, a first driving roller 309, a second bearing bracket 310, a second driving roller 311, a driving motor 312 and a wire winding roller 313. The limit disc 307 is located outside the bearing ring 306. The upper end of the mounting plate 303 is fixedly installed with a strut 304. A rod seat 305 is fixedly installed on the strut 304. A shaft rod is installed on the rod seat 305. A bearing ring 306 is installed on the shaft rod of the rod seat 305. The four groups of rod seats 305, bearing rings 306 and limit discs 307 are distributed above the mounting plate 303. The upper end of the first support 1 is fixedly installed with a first bearing bracket 308. A first driving roller 309 is installed on the first bearing bracket 308. The upper end of the second support 2 is fixedly installed with a second bearing bracket 310. A second driving roller 311 is installed on the second bearing bracket 310. The right end of the second support 2 is fixedly installed with a driving motor 312. The transmission end of the driving motor 312 is installed with a wire winding roller 313;

[0023] The support rod 301 provides stable support for the hydraulic push rod 302, ensuring that the hydraulic push rod 302 can generate sufficient pulling force when starting, quickly pulling down the mounting plate 303 and the limiting structure, thereby effectively buffering the stress of the copper wire body 5. The hydraulic push rod 302 can be quickly started according to the stress signal transmitted by the monitoring mechanism 4, pulling down the mounting plate 303 and the limiting structure to buffer the stress of the copper wire body 5, which helps to prevent the copper wire body 5 from breaking during the stretching process and improves production efficiency. The mounting plate 303 is connected to the hydraulic push rod 302 and can quickly respond to the pulling force of the hydraulic push rod 302 and move downward, thereby realizing the stress buffering of the copper wire body 5. The limiting disc 307 limits the copper wire body 5 to pass through its center, effectively controlling the stretching degree of the copper wire body 5;

[0024] The monitoring mechanism 4 includes a mounting frame 401 and an electromagnetic sensor 402. The front end of the second bearing frame 310 is fixedly installed with a mounting frame 401, and the electromagnetic sensor 402 is installed on the mounting frame 401; the electromagnetic sensor 402 can detect the change of the electromagnetic characteristics of the copper wire body 5 and monitor the stress state of the copper wire body 5 in real time.

[0025] The working principle of the present utility model is as follows: The wire guiding and stretching device for bonding copper wires is additionally provided with a regulating mechanism 3 and a monitoring mechanism 4. Before using the wire guiding and stretching device for bonding copper wires, it is necessary to pre-energize the hydraulic push rod 302, drive motor 312, and electromagnetic sensor 402 inside the regulating mechanism 3 and the monitoring mechanism 4 and connect them to the control terminal. The electromagnetic sensor 402 is pre-activated, and in the stress-free state, the electromagnetic characteristics of the copper wire are recorded as a reference standard, which may involve measuring parameters such as the resistance, inductance, or magnetic permeability of the copper wire in the stress-free state. When using the wire guiding and stretching device for bonding copper wires, the copper wire body 5 is coiled and fixed on the wire reel 313. The drive motor 312 is started to drive the wire reel 313, and the copper wire body 5 can be pulled from left to right. The copper wire body 5 passes through the first bearing bracket 308 and the first transmission roller 309 and reaches the middle of the four groups of limiting discs 307. The four groups of limiting discs 307 are limiting structures that can effectively perform stretching operations on the copper wire body 5 to achieve the effect of stretching the copper wire body 5. The copper wire body 5 passing through the limiting structure will pass through the second bearing bracket 310 and the second transmission roller 311 and be coiled on the wire reel 313; during the above operation process, the electromagnetic sensor 402 in the monitoring mechanism 4 uses an electromagnetic measurement device to apply an AC or DC excitation signal to the electromagnetic sensor 402. This signal will generate an alternating magnetic field in the copper wire. When the copper wire is subjected to stress, its electromagnetic characteristics will change. The electromagnetic sensor 402 will sense the change in the electromagnetic field caused by the stress change and generate a voltage or current signal. The voltage or current signal sensed by the electromagnetic sensor 402 is input to the control terminal, and then the hydraulic push rod 302 in the regulating mechanism 3 is activated to quickly pull down the mounting plate 303 and the limiting structure, thereby buffering the stress of the copper wire body 5 and avoiding situations such as the fracture of the copper wire body 5. After completing the above operation, the height of the limiting structure can be adjusted again according to needs for the stretching operation of the copper wire body 5; in summary, the regulating mechanism 3 and the monitoring mechanism 4 complement each other. The monitoring mechanism 4 uses electromagnetic measurement technology to judge the stress change of the copper wire body 5 by comparing electromagnetic characteristics and transmits the stress information to the control terminal. The regulating mechanism 3 is activated to perform a positioning operation on the limiting structure for stretching the copper wire body 5, thereby quickly adjusting the stress of the copper wire body 5 and avoiding the fracture of the copper wire body 5, effectively improving the practicability and reliability of the device.
