Description

Technical Field

[0001] The present application relates to the technical field of wire bonding equipment, and in particular to a filament winding wire bonding machine. Background Art

[0002] Wire bonding machines are indispensable key equipment in the electronics manufacturing industry. With the increasingly obvious trend of miniaturization of electronic products, the market demand for high-precision and high-efficiency wire bonding machines has increased significantly. These wire bonding machines not only improve production efficiency, but also ensure the quality and reliability of products. However, for wire harnesses with very fine wires, traditional wire bonding machines face many challenges in the welding process, especially in ensuring the strength of solder joints. At present, there are many solutions on the market to meet the demand for fine wire bonding. For example, some wire bonding machines use high-precision laser welding technology to achieve fine wire welding by precisely controlling laser energy; others use ultrasonic welding technology to complete the welding process using the heat generated by high-frequency vibration; and some wire bonding machines increase the amount of solder to enhance the stability of solder joints. In addition, some equipment improves the design of the welding head, such as increasing the fineness and flexibility of the welding head, to accommodate thinner wires. Although the above methods have solved the problem of fine wire bonding to a certain extent, there are still some shortcomings. Especially for extremely fine wires, it is difficult for traditional wire bonding machines to ensure the strength of the solder joint while avoiding damage or breakage caused by overheating of the solder joint. In addition, when welding thin wires, because the welding point of the welding gun is too small, sparks often occur due to control errors, which can easily damage electronic components. Therefore, how to achieve efficient and reliable thin wire welding while ensuring the strength of the welding point has become a technical problem that needs to be solved urgently.

The pneumatic element is used to drive the first clamping block 213 and the second clamping block 215 to move. In order to enable the first clamping block 213 and the second clamping block 215 to rebound away from each other when not driven by the pneumatic element, a return spring 216 is placed between the two sliders 212, so that after the first clamping block 213 and the second clamping block 215 are clamped by the pneumatic element, the pneumatic element does not work, and the return spring 216 bounces the first clamping block 213 and the second clamping block 215 apart from each other. The cross-sectional shape of the first clamping block 213 and the second clamping block 215 is semicircular.

A through hole is provided on the ceramic seat 433, and a ceramic ring 431 is fixedly provided in the through hole. The shape of the ceramic ring 431 is an unclosed circular ring, that is, the ceramic ring 431 is provided with a gap to form a wiring gap 432, and the setting of the wiring gap 432 disconnects the ceramic ring 431. When the first clamp 213 and the second clamp 215 are in a clamped state, the ceramic ring 431 can be sleeved upward from the bottom of the first clamp 213 and the second clamp 215, and the first clamp 213 and the second clamp 215 are provided with a positioning shoulder 214 at the same height position, and the positioning shoulder 214 is used to limit the ceramic ring 431.

[0033] The wire welding mechanism also includes a winding drive assembly, which includes an electric slide 31, which is set as a double slide, and the two slides 311 can be controlled independently. The electric slide 31 includes two slides 311, on which a downward pressure cylinder 312 is fixedly arranged, and a rotating motor 313 is fixedly arranged on the output shaft of the downward pressure cylinder 312, and the output shaft of the rotating motor 313 is fixedly connected to the winding clamp 21. Through the setting of the winding drive assembly, the winding drive assembly can complete the movement in the horizontal and vertical directions, and the winding clamp 21 can be driven by the rotating motor 313 to rotate.

[0034] The welding wire assembly also includes a de-wire cylinder 42, which is fixedly arranged on the slide 311, and the output shaft of the de-wire cylinder 42 is fixedly connected to the welding wire arm 41, and the de-wire cylinder 42 drives the welding wire arm 41 to move up and down. The welding wire arm 41 is tilted relative to the de-wire cylinder 42, and a support plate 434 is fixedly arranged at one end of the de-wire arm 43 away from the ceramic seat 433, and the support plate 434 is vertically arranged and perpendicular to the material conveyor belt 51, and the support plate 434 is used to support the de-wire arm 43, and the de-wire arm 43 can abut against the transmission belt, so that the de-wire arm 43 can remain stable in an inclined state, thereby improving the stability of spot welding. The top of the de-wire arm 43 is slidably connected to the welding wire arm 41 through a slide rail 435, and the setting of the slide rail 435 enables the de-wire arm 43 to slide at an inclined angle with the welding wire arm 41.

[0035] Reference Figure 4 and Figure 5The wire stripping mechanism includes a wire stripper, and the wire stripper includes a wire routing seat 136. Two wire extrusion plates 131 are arranged opposite to each other on the wire routing seat 136. A tool clearance opening 137 is formed between the two wire extrusion plates 131. A wire extrusion wheel 134 is arranged on each side of the two wire extrusion plates 131 close to the tool clearance opening 137. The wire extrusion wheel 134 is set as a driving wheel driven by a motor to rotate. The wire wrapped with an insulating hose passes through the two wire extrusion wheels 134. When the motor drives the wire extrusion wheel 134 to rotate, it can generate a pulling force on the wire. A baffle 1341 is fixedly arranged above and below the wire extrusion plate 131. The baffle 1341 is set to limit the wire so that the wire does not deviate from the route. In order to remove the insulating hose of the wire, the wire stripper also includes a wire stripping knife 135, which is vertically fixed on the top of the wiring seat 136 and located in the tool clearance opening 137. The wire stripping knife 135 is arranged on the wire extrusion wheel 134 close to the feed end of the wire, so that the bottom wire of the insulating hose is cut by the wire stripping knife 135 before the wire passes through the wire extrusion wheel 134. The wire stripping knife 135 cuts the insulating hose at the bottom of the wire, and then applies pressure to both ends of the wire through the wire extrusion wheel 134 while rotating, so that the originally cut insulating hose is spread out to all sides. A guide plate 1371 and an electric cutter 1372 are provided at one end of the wire extrusion plate 131 near the wire outlet direction. A U-shaped groove is provided on the guide plate 1371. The guide plate 1371 extends obliquely into the cutter opening 137. The stripped insulating hose can be guided by the surface of the guide plate 1371 obliquely upward to the electric cutter 1372, and the exposed metal filaments pass through the U-shaped groove in the middle of the guide plate 1371. The electric cutter 1372 is set as normal, and the electric cutter 1372 is set obliquely above the guide plate 1371 to cut the insulating hose.

[0036] The wire stripping mechanism also includes a wire winding drum 11 and a wire routing substrate 12, the wire routing substrate 12 is fixedly connected to the wire routing seat 136, and a wire routing hole 121 is provided in the wire routing substrate 12. The wire winding drum 11 is used to store the wire stored in a coiled shape, and the wire winding drum 11 rotates to release the wire, and the wire passes through the wire routing hole 121 provided in the wire routing substrate 12, and is guided to the wire routing seat 136 by entering the hole for cutting. The wire stripping mechanism also includes a pneumatic wire fixing clamp 138 and a pneumatic wire moving clamp 139, and the clamping surface of the pneumatic wire fixing clamp 138 is provided with a blade, a wire routing roller of the wire winding drum 11 and a wire routing substrate 12, and the wire routing roller is arranged between the wire winding drum 11 and the wire routing substrate 12, and the wire routing roller is driven to rotate by a motor, and two wire routing rollers are provided, and the two wire routing rollers pull the wire of the wire winding drum 11 out and send it into the wire routing hole 121 by rotation. The pneumatic wire fixing clamp 138 is arranged between the wire winding drum 11 and the wire routing roller. The pneumatic wire fixing clamp 138 and the pneumatic wire moving clamp 139 are connected to a mechanical arm, and the pneumatic wire fixing clamp 138 and the pneumatic wire moving clamp 139 are controlled by the mechanical arm to move the wire.

[0037] The implementation principle of the embodiment of the present application is as follows: after the equipment is started, the wire stripping, feeding and welding processes will be automatically completed. When the wire stripping process is performed, the wire routing roller rotates to pull the wire on the wire winding reel 11 and guides it along the wire routing hole 121 to the wire stripper for wire stripping. After the insulating hose of the wire is pulled apart, the pneumatic wire fixing clamp 138 cuts the wire and clamps the wire to pull it out of the wire routing hole 121, and the pneumatic wire moving clamp 139 clamps the wire and moves toward the direction of the wire winding clamp 21. The wire winding drive assembly drives the wire winding clamp 21 to move, so that the wire winding clamp 21 clamps one end of the wire that exposes the filament. After the wire winding clamp 21 clamps one end of the wire, the pneumatic wire moving clamp 139 continues to clamp the other end of the wire. Before winding the wire, the wire stripping cylinder 42 drives the wire stripping arm 43 and the wire welding arm 41 to move upward as a whole. During the upward movement, the wire welding arm 41 slides upward along the guide rail, so that the wire welding arm 41 is moved away from directly under the wire winding clamp 21, and the ceramic ring 431 is facing the first clamp block 213 and the second clamp block 215. Due to the setting of the wiring gap 432, when the ceramic ring 431 moves upward, the filament can pass through the wiring gap 432 and the ceramic ring 431 is sleeved on the first clamp block 213 and the second clamp block 215. The ceramic ring 431 is driven by the wire stripping cylinder 42 until it abuts against the positioning shoulder 214 to limit the position.

[0038] The winding drive assembly drives the winding jaw 21 to rotate and wind the wire. Since the filament is set as a metal wire that can be shaped, the filament is wound several times after the winding jaw 21 rotates, and then the pneumatic element does not work. The first clamp block 213 and the second clamp block 215 loosen the filament under the elastic force of the return spring 216. Since the surfaces of the first clamp block 213 and the second clamp block 215 are both set as arc surfaces, the filament is now coiled on the first clamp block 213 and the second clamp block 215. The de-wire cylinder 42 drives the ceramic ring 431 to move down along the first clamp block 213 and the second clamp block 215 to remove the rolled filament from the first clamp block 213 and the second clamp block 215.

[0039] The material conveyor belt 51 moves the electronic product to the bottom of the welding wire assembly, and the removed filament is pressed by the ceramic ring 431 at the welding position of the electronic product. The wire-off cylinder 42 continues to move downward, and the wire-off arm 41 moves downward along the slide rail 435 to the top of the ceramic ring 431, and the spot welding gun 411 and the ignition rod 412 weld the filament and the electronic product. After the welding is completed, the wire-off cylinder 42 drives the wire-off arm 41 and the wire-off arm 43 to move upward, and the pneumatic wire-moving clamp 139 releases the wire, completing a welding process, and then the device continues to repeat this process.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
