Description

Technical Field

[0001] This application relates to the field of wire bonding equipment technology, and in particular to a fine wire winding wire bonding machine. Background Technology

[0002] Wire bonding machines are indispensable key equipment in the electronics manufacturing industry. With the increasing trend of miniaturization in electronic products, the market demand for high-precision, high-efficiency wire bonding machines has increased significantly. These machines not only improve production efficiency but also ensure product quality and reliability. However, for bonding very fine wire bundles, traditional wire bonding machines face many challenges during the welding process, especially in ensuring solder joint strength. Currently, various solutions have emerged in the market to address the need for fine wire bonding. For example, some wire bonding machines employ high-precision laser welding technology, achieving fine wire bonding through precise control of laser energy; others use ultrasonic welding technology, utilizing the heat generated by high-frequency vibration to complete the welding process; still others enhance solder joint stability by increasing the amount of solder. Furthermore, some machines improve the design of the welding head, such as increasing its precision and flexibility, to accommodate even finer wires. While these methods address the problems of fine wire bonding to some extent, some shortcomings remain. Especially for extremely fine wires, traditional wire bonding machines struggle to ensure solder joint strength while preventing damage or breakage due to overheating. Furthermore, when welding fine wires, the welding points of the welding gun are too small, often leading to sparking due to control errors, which can easily damage electronic components. Therefore, how to achieve efficient and reliable fine wire welding while ensuring the strength of the solder joint has become an urgent technical problem to be solved. Summary of the Invention

[0003] To overcome the above-mentioned technical problems, this application provides a fine wire winding and bonding machine.

[0004] This application provides a fine wire winding and bonding machine, which adopts the following technical solution:

[0005] A fine wire winding and bonding machine includes a wire stripping mechanism, a welding mechanism, and a feeding mechanism. The welding mechanism includes a wire winding assembly, which includes wire winding jaws. The wire winding jaws include pneumatic components, jaw members, a return spring, and a fixed base. The jaw members include a first clamping block and a second clamping block. Positioning shoulders are provided at the same height position on both the first clamping block and the second clamping block. The welding mechanism includes a wire welding arm and a wire release arm. A spot welding gun and a ignition rod are fixedly installed on the wire welding arm. A ceramic seat is provided at the end of the wire release arm. An angle is provided between the ceramic seat and the wire release arm. A through hole is provided on the ceramic seat. A ceramic ring is fixedly installed in the through hole. The ceramic ring is in the shape of a non-closed annulus and has a notch to form a wire routing notch.

[0006] By adopting the above technical solution, and by configuring the wire winding clamps, including a first clamping block and a second clamping block, which are used to clamp the fine wire and rotate it for winding, the welded area of ​​the wound fine wire is increased, resulting in larger weld points. This improves the welding stability and tensile strength of the fine wire. The ceramic seat is used to place a ceramic ring. The ceramic ring is made of ceramic material, and its electrical conductivity and high-temperature resistance prevent sparks from flying, thus avoiding sparking during spot welding of the fine wire.

[0007] In one specific implementation, a slider is fixedly provided on the top of both the first clamping block and the second clamping block, and a groove is provided on the fixed base. The first clamping block and the second clamping block are slidably disposed in the groove through the slider, and the reset spring is placed between the two sliders.

[0008] By adopting the above technical solution, the first clamping block and the second clamping block can slide relative to each other through the cooperation of the slider and the slide groove, so that the pneumatic component can drive them. The return spring is placed between the two sliders, so that the two clamping blocks can be reset under the action of the return spring when the pneumatic component is not working.

[0009] In one specific implementation, the cross-sectional shape of the first clamping block and the second clamping block is semi-circular.

[0010] By adopting the above technical solution, the shape of a single clamping block is set to a semicircle, so that the two clamping blocks can form a whole circle when closed, which facilitates the winding and unwinding of the wire.

[0011] In one specific implementation, the feeding mechanism includes a feeding platform located directly below the welding arm, the feeding platform including a material conveyor belt.

[0012] By adopting the above technical solution, the feeding mechanism is set up to transport electronic products waiting to be welded.

The electric slide table includes a slide table, on which a pressing cylinder is fixedly mounted. A rotary motor is fixedly mounted on the output shaft of the pressing cylinder, and the output shaft of the rotary motor is fixedly connected to the wire winding gripper.

[0014] By adopting the above technical solution, the winding drive assembly is used to drive the winding jaws to complete horizontal movement, vertical movement and rotation, so that the winding jaws can transfer and wind the wire after clamping the filament.

[0015] In one specific implementation, the welding mechanism further includes a wire-removing cylinder, the output shaft of which is fixedly connected to the welding arm. The welding arm is inclined relative to the wire-removing cylinder, and a support plate is fixedly provided at the end of the wire-removing arm away from the ceramic seat. The top of the wire-removing arm is slidably connected to the welding arm via a slide rail.

[0016] By adopting the above technical solution, the top of the wire-removing arm and the wire-welding arm are slidably connected by a slide rail, and the wire-welding arm is tilted relative to the wire-removing cylinder, so that the wire-removing arm can achieve the technical effect of tilting and sliding when sliding up and down. When the wire-removing cylinder presses down on the wire-removing arm and the wire-welding arm, the wire-welding arm can be positioned directly above the wire-removing arm. When the wire-removing cylinder moves up on the wire-removing arm and the wire-welding arm, the wire-welding arm tilts and moves up, so that the wire-removing arm is directly facing the wire-winding clamp.

[0017] In one specific implementation, the wire stripping mechanism includes a wire stripper, the wire stripper includes a wire feeding seat, two extrusion plates are arranged opposite each other on the wire feeding seat, a cutter clearance opening is formed between the two extrusion plates, an extrusion wheel is arranged on the side of each of the two extrusion plates near the cutter clearance opening, and a baffle is fixedly arranged above and below each of the extrusion plates.

[0018] By adopting the above technical solution, the extrusion wheel is used to apply pressure to both sides of the conductor, causing the insulating tubing wrapped around the conductor to be squeezed and stretched open. The baffle is set to restrict the direction of the conductor, so that the conductor does not deviate from the direction when the extrusion wheel moves.

[0019] In one specific implementation, the wire stripper further includes a wire stripping knife, which is vertically fixed on the top of the wire feeding seat and located inside the knife clearance opening. The end of the extrusion plate near the wire exit direction is provided with a guide plate and an electric cutting shear, and a U-shaped groove is provided on the guide plate.

[0020] By adopting the above technical solution, the guide plate is used to guide the insulated hose after it has been spread out, so that the insulated hose moves along the surface of the guide plate toward the direction of the electric cutter, and the exposed metal wire passes through the U-shaped groove in the middle of the guide plate.

[0021] In one specific implementation, the wire stripping mechanism further includes a winding reel, a wire feeding roller, and a wire feeding substrate. The wire feeding substrate is fixedly connected to the wire feeding base, and a wire feeding hole is formed in the wire feeding substrate. The wire feeding roller is disposed between the winding reel and the wire feeding substrate.

[0022] By adopting the above technical solution, the winding reel, the wire guide roller, and the wire guide board are used for wire output and for guiding the direction of the wire.

[0023] In one specific implementation, the wire stripping mechanism further includes a pneumatic wire-fixing gripper and a pneumatic wire-moving gripper, wherein the clamping surface of the pneumatic wire-fixing gripper is provided with a cutting edge.

[0024] By adopting the above technical solution, the clamping surface of the pneumatic wire clamp is provided with a blade to achieve the technical effect of cutting the wire harness, while the pneumatic wire moving clamp is used to move the wire and, during the welding process, the pneumatic wire moving clamp clamps to clamp and fix the end of the wire.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The winding assembly's gripper section includes pneumatic components, gripper pieces, a return spring, and a mounting base. The gripper pieces consist of a first clamping block and a second clamping block, both with positioning shoulders at the same height. This design allows the first and second clamping blocks to effectively clamp the filament and rotate it during winding, thereby increasing the welding area and improving the stability of the weld joint. The return spring ensures that the two clamping blocks can quickly return to their original position when the pneumatic components are not operating.

[0027] 2. The welding mechanism includes a wire-welding arm and a wire-removing arm. Specifically, the ceramic base has a through-hole into which a ceramic ring is placed. This ceramic ring is a non-closed circular ring with notches at appropriate locations to create wire routing gaps, facilitating the passage of fine wires. The ceramic material possesses electrical conductivity and high-temperature resistance, effectively preventing spark splashing and avoiding arcing during the welding process.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] In the description of the invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0034] This application discloses a fine wire winding and bonding machine, referring to... Figure 1 , Figure 2 and Figure 3It includes a wire stripping mechanism, a welding mechanism, and a feeding mechanism. The welding mechanism includes a wire winding assembly, which includes a wire winding gripper 21. The wire winding gripper 21 includes a pneumatic component, a gripper piece 211, a return spring 216, and a fixed base 217. The gripper piece 211 includes a first clamping block 213 and a second clamping block 215, which are used to clamp the fine wire. The top of the first clamping block 213 and the second clamping block 215 are both fixedly provided with sliders 212. The fixed base 217 is provided with a sliding groove 218. The first clamping block 213 and the second clamping block 215 are slidably disposed in the sliding groove 218 through the sliders 212. The first clamping block 213 and the second clamping block 215 slide relative to each other through the cooperation of the sliders 212 and the sliding groove 218. The pneumatic element is used to drive the first clamping block 213 and the second clamping block 215 to move. In order to allow the first clamping block 213 and the second clamping block 215 to bounce away from each other when not driven by the pneumatic element, the return spring 216 is placed between the two sliders 212. After the first clamping block 213 and the second clamping block 215 are driven and 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 away from each other. The cross-sectional shape of the first clamping block 213 and the second clamping block 215 is semi-circular. When the first clamping block 213 and the second clamping block 215 are clamped, the first clamping block 213 and the second clamping block 215 can together form a cylindrical shape.

[0035] The welding mechanism includes a wire bonding arm 41 and a wire removal arm 43. A spot welding torch 411 and a spark rod 412 are fixedly mounted on the wire bonding arm 41. The spot welding torch 411 and the spark rod 412 are arranged adjacent to each other. When the spark rod 412 is used in conjunction with the spot welding torch 411, it generates a spark at the nozzle of the spot welding torch 411, thereby igniting the welding process for welding fine wires and electronic products. The feeding mechanism includes a feeding platform 5 located directly below the welding arm. The feeding platform 5 includes a material conveyor belt 51. The material conveyor belt 51 is used to transport electronic products waiting to be welded.

[0036] To prevent sparks from the spot welding gun 411 during welding, a ceramic seat 433 is provided at the end of the wire-removing arm 43. An angle is provided between the ceramic seat 433 and the wire-removing arm 43, allowing the wire-removing arm 43 to tilt upwards when the ceramic seat 433 is parallel to the material conveyor belt 51. A through hole is provided on the ceramic seat 433, and a ceramic ring 431 is fixedly installed within the through hole. The ceramic ring 431 is a non-closed ring, with a notch forming a wiring notch 432, which breaks the ceramic ring 431. When the first clamping block 213 and the second clamping block 215 are clamped, the ceramic ring 431 can be fitted upwards from the bottom of the first clamping block 213 and the second clamping block 215. Positioning shoulders 214 are provided at the same height on both the first clamping block 213 and the second clamping block 215, and these positioning shoulders 214 are used to limit the movement of the ceramic ring 431.

[0037] The wire bonding mechanism also includes a wire winding drive assembly, which includes an electric slide table 31. The electric slide table 31 is a double slide table, and both slide tables 311 can be controlled independently. The electric slide table 31 includes two slide tables 311, and a pressing cylinder 312 is fixedly mounted on each slide table 311. A rotary motor 313 is fixedly mounted on the output shaft of the pressing cylinder 312, and the output shaft of the rotary motor 313 is fixedly connected to the wire winding gripper 21. Through the configuration of the wire winding drive assembly, the wire winding drive assembly can complete the horizontal and vertical movement, and the wire winding gripper 21 can be driven by the rotary motor 313 to rotate. After the wire winding gripper 21 clamps the filament, the rotation can complete the winding action of the filament.

[0038] The welding mechanism also includes a wire-removing cylinder 42, which is fixedly mounted on the slide table 311. The output shaft of the wire-removing cylinder 42 is fixedly connected to the welding arm 41, and the wire-removing cylinder 42 drives the welding arm 41 to move up and down. The welding arm 41 is inclined relative to the wire-removing cylinder 42. A support plate 434 is fixedly mounted on the end of the wire-removing arm 43 away from the ceramic seat 433. The support plate 434 is vertically mounted and perpendicular to the material conveyor belt 51. The support plate 434 is used to support the wire-removing arm 43, which can abut against the conveyor belt, so that the wire-removing arm 43 can remain stable in the inclined state, thereby improving the stability of spot welding. The top of the wire-removing arm 43 is slidably connected to the welding arm 41 through a slide rail 435. The slide rail 435 allows the wire-removing arm 43 to slide at an inclined angle with the welding arm 41.

[0039] Reference Figure 4 and Figure 5The wire stripping mechanism includes a wire stripper, which includes a wire guide seat 136. Two extrusion plates 131 are oppositely arranged on the wire guide seat 136, with a cutter clearance opening 137 formed between the two extrusion plates 131. Each of the two extrusion plates 131 has an extrusion wheel 134 on its side near the cutter clearance opening 137. The extrusion wheel 134 is a drive wheel that rotates via a motor. The wire wrapped in insulated tubing passes through the two extrusion wheels 134. When the motor drives the extrusion wheels 134 to rotate, it generates a pulling force on the wire. A baffle 1341 is fixedly installed above and below each of the extrusion plates 131. The baffles 1341 are used to limit the wire and prevent it from deviating from its path. To remove the insulating tubing from the conductor, the wire stripper also includes a wire stripping blade 135. The wire stripping blade 135 is vertically fixed on the top of the wire feed seat 136 and located inside the blade clearance opening 137. The wire stripping blade 135 is positioned near the feed end of the conductor on the extrusion roller 134, so that the bottom wire of the insulating tubing is cut by the wire stripping blade 135 before the conductor passes through the extrusion roller 134. The wire stripping blade 135 cuts open the insulating tubing at the bottom of the conductor, and then the extrusion roller 134 applies pressure to both ends of the conductor while rotating, causing the originally cut insulating tubing to open up in all directions. A guide plate 1371 and an electric cutter 1372 are provided at one end of the extrusion plate 131 near the wire exit direction. The guide plate 1371 has a U-shaped groove and extends obliquely into the cutter clearance opening 137. The stripped insulating hose can be guided obliquely upward by the surface of the guide plate 1371 to the electric cutter 1372, while the exposed metal wire passes through the U-shaped groove in the middle of the guide plate 1371. The electric cutter 1372 is configured as usual and is positioned obliquely above the guide plate 1371 to cut the insulating hose.

[0040] The wire stripping mechanism also includes a winding reel 11 and a wire routing substrate 12. The wire routing substrate 12 is fixedly connected to the wire routing base 136, and a wire routing hole 121 is provided in the wire routing substrate 12. The winding reel 11 is used to store the wires stored in a coil. The winding reel 11 rotates to release the wires, which pass through the wire routing hole 121 in the wire routing substrate 12 and are guided to the wire routing base 136 for cutting through the inlet hole. The wire stripping mechanism also includes a pneumatic wire holding gripper 138 and a pneumatic wire moving gripper 139. The clamping surface of the pneumatic wire holding gripper 138 has a cutting edge. The winding reel 11 has a wire routing roller and the wire routing substrate 12. The wire routing roller is disposed between the winding reel 11 and the wire routing substrate 12. The wire routing roller is driven to rotate by a motor. There are two wire routing rollers. The two wire routing rollers pull out the wires from the winding reel 11 and feed them into the wire routing hole 121 by rotating. The pneumatic wire-fixing gripper 138 is disposed between the winding reel 11 and the wire-moving roller. The pneumatic wire-fixing gripper 138 and the pneumatic wire-moving gripper 139 are connected to a robotic arm. The robotic arm controls the pneumatic wire-fixing gripper 138 and the pneumatic wire-moving gripper 139 to move the wire.

[0041] The implementation principle of this application embodiment is as follows: After the equipment is started, it will automatically complete the wire stripping, feeding, and welding processes. During the wire stripping process, the wire feeding roller rotates to pull out the wire on the winding reel 11 and guide it along the wire feeding hole 121 into the wire stripper for stripping. After the insulating tubing of the wire is opened, the pneumatic wire clamping claw 138 cuts the wire and clamps it to pull it out from the wire feeding hole 121. The pneumatic wire moving claw 139 clamps the wire and moves it toward the winding claw 21. The winding drive assembly drives the winding claw 21 to move, so that the winding claw 21 clamps the end of the wire with the exposed filaments. After the winding claw 21 clamps one end of the wire, the pneumatic wire moving claw 139 continues to clamp the other end of the wire. Before winding, the wire release cylinder 42 drives the wire release arm 43 and the wire bonding arm 41 to move upward as a whole. During the upward movement, the wire bonding arm 41 slides upward along the guide rail, so that the wire bonding arm 41 moves away from directly below the winding clamp 21 and the ceramic ring 431 is aligned with the first clamp 213 and the second clamp 215. Due to the setting of the wire routing notch 432, when the ceramic ring 431 moves upward, the filament can pass through the wire routing notch 432 and the ceramic ring 431 is fitted onto the first clamp 213 and the second clamp 215. The ceramic ring 431 is driven by the wire release cylinder 42 until it abuts against the positioning shoulder 214 and is limited.

[0042] The winding drive assembly drives the winding jaws 21 to rotate and wind the wire. Since the filament is made of metal wire and can be shaped, the filament is wound several times after the winding jaws 21 rotate. Then, the pneumatic components stop working, and the first clamping block 213 and the second clamping block 215 release the filament under the elastic force of the return spring 216. Since the outer surfaces of the first clamping block 213 and the second clamping block 215 are both curved, the filament is now coiled on the first clamping block 213 and the second clamping block 215. The wire release cylinder 42 drives the ceramic ring 431 to move down along the first clamping block 213 and the second clamping block 215, releasing the coiled filament from the first clamping block 213 and the second clamping block 215.

[0043] The material conveyor belt 51 moves the electronic product to below the welding mechanism. The detached wire is pressed by the ceramic ring 431 onto the welding position of the electronic product. The wire-detaching cylinder 42 continues to move downward, and the wire-welding arm 41 moves downward at an angle along the slide rail 435 to the top of the ceramic ring 431. The spot welding gun 411 and the ignition rod 412 weld the wire and the electronic product. After welding is completed, the wire-detaching cylinder 42 drives the wire-welding arm 41 and the wire-detaching arm 43 to move upward, and the pneumatic wire-moving gripper 139 releases the wire, thus completing one welding process. The equipment then continues to repeat this process.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
