Description

Technical Field

[0001] This invention relates to the field of electronic component processing technology, and in particular to a high-precision flattening and welding mechanism for nickel wire and substrate. Background Technology

[0002] In the production process of nickel wire welding to ceramic substrates in the tantalum capacitor and resistor industry, current technology still mainly relies on manual loading and unloading and multiple manual processes to complete the production. This production mode is not only labor-intensive, requiring operators to continuously exert physical strength to complete material transfer and process connection, but also suffers from low production efficiency—the manual operation is slow, the production cycle of a single product is long, and it is difficult to meet the needs of large-scale production; at the same time, during the manual material transfer process, subjective factors such as differences in operating techniques and force can easily introduce unstable factors such as material positioning deviation and bumps, which directly lead to fluctuations in product quality and increase the probability of defective products. Furthermore, existing manual production methods face significant safety and health hazards and have functional limitations. On the one hand, the welding process generates a large amount of welding fumes, and long-term exposure to this environment poses a significant health threat to the respiratory system of operators. Simultaneously, the production equipment requires high voltage operation, and prolonged repetitive manual operation can easily lead to distraction and fatigue, increasing the risk of irreversible physical harm such as electric shock. On the other hand, manual production is difficult to be compatible with various specifications of nickel wire and substrate. Different specifications of products require separate operating procedures or even equipment, resulting in high equipment investment costs for enterprises and low utilization of existing equipment, further increasing overall production costs. Therefore, this invention proposes a high-precision flattening and welding mechanism for nickel wire and substrate to solve the problems existing in the prior art. Summary of the Invention

[0003] To address the aforementioned issues, this invention proposes a high-precision flattening and welding mechanism for nickel wire and substrate. This mechanism, through the establishment of automated structures such as a substrate loading position, a substrate handling module, a flattening position, a welding position, and a finished product unloading position, achieves fully automated operation from material loading, nickel wire flattening, substrate welding to finished product unloading, completely replacing manual loading and unloading and manual transfer processes.

[0004] To achieve the objectives of this invention, the invention is implemented through the following technical solution: a high-precision flattening and welding mechanism for nickel wire and substrate, comprising a base and a substrate loading position, a carrier, a nickel wire feeding and cutting module, a substrate handling module, a nickel wire turntable, a flattening position, a welding position, a marking position, and a finished product unloading position disposed on the base. The substrate loading position supplies the substrate, the substrate handling module is used to deliver the substrate to the carrier, and the carrier is used to deliver the substrate to the welding position. The nickel wire turntable is rotatable and has several pneumatic grippers at equal angles. The nickel wire feeding and cutting module is used to feed and cut the nickel wire. The pneumatic grippers are used to hold the cut nickel wire and follow the rotation of the nickel wire turntable to the flattening position for flattening, and then to the welding position. The welding position is used to weld the nickel wire and the substrate, and the welding position is equipped with a correction carrier and a correction guide position to guide the welding position. After completion, the carrier resets the substrate, and the substrate transport module sends the substrate to the marking position for marking and then to the finished product unloading position.

[0005] A further improvement is that the carrier includes a guide rail, a motion seat, and a carrier. The guide rail is disposed on the base, the motion seat is movably disposed on the guide rail, and the carrier is connected to the motion seat via a cylinder. The carrier is used to support the substrate.

[0006] A further improvement is that the substrate handling module includes a first lead screw drive frame, a first movable seat, and a mounting frame. The first movable seat is movably mounted on the first lead screw drive frame, and the mounting frame is lifted and lowered on the first movable seat. The mounting frame is provided with a handling frame, and the handling frame is provided with a suction nozzle for adsorbing the substrate.

[0007] A further improvement is that the welding position includes a second lead screw drive frame, a second movable seat, and a welding module. The second movable seat is movably mounted on the second lead screw drive frame, and the welding module is lifted and lowered on the second movable seat.

[0008] A further improvement is that the calibration guide position includes a fixed frame and a calibration probe. The fixed frame is connected to one end of the front side of the second lead screw drive frame, and the calibration probe is mounted on the fixed frame with the probe end facing the welding position.

[0009] A further improvement is that the nickel wire feeding and cutting module includes a nickel wire spool, a guide wheel assembly, a straightening wheel assembly, a cleaning block, a feeding assembly, and a cutter. The nickel wire spool is used to release the nickel wire, the feeding assembly is used to pull the nickel wire for conveying, the guide wheel assembly is used to guide the nickel wire, the straightening wheel assembly is used to straighten the nickel wire, the nickel wire passes through the cleaning block for cleaning, and the cutter is used to cut the nickel wire.

[0010] A further improvement is that the feeding assembly includes a feeding wheel and a support wheel, with the nickel wire passing between the feeding wheel and the support wheel, and the feeding wheel being driven to rotate by a motor.

[0011] A further improvement is made in that: the flattening position includes a fixed position, an adjusting support, and a supporting base. The adjusting support is located on one side of the fixed position, and the supporting base is located on the adjusting support. A pressing module is elastically and movably installed above one side of the fixed position, and the lower end of the pressing module is provided with a pressing block adapted to the supporting base. A servo motor is located above the fixed position, and the output end of the servo motor is connected to a cam. The top of the pressing module is provided with an adapter wheel adapted to the cam.

[0012] A further improvement is that the marking position includes a bracket, a transfer seat, and a marking frame. The transfer seat is elliptical and mounted on one side of the bracket, and the marking frame is movably mounted on the other side of the bracket. An ink pad is provided under the marking frame. The transfer seat is used to support the substrate, and one end of the transfer seat is provided with ink that is compatible with the ink pad.

[0013] A further improvement is that a multi-axis drive module is provided on one side above the base, the finished product unloading position is located on the multi-axis drive module, and the multi-axis drive module is used to drive the finished product unloading position to move laterally and longitudinally.

[0014] The beneficial effects of this invention are as follows: 1. This invention achieves fully automated operation from material loading, nickel wire flattening, substrate welding to finished product unloading by setting up automated structures such as substrate loading position, substrate handling module, flattening position, welding position, and finished product unloading position. It completely replaces manual loading and unloading and manual transfer processes, which not only greatly reduces the input of human labor, but also avoids problems such as material positioning deviation and bumps caused by subjective factors in manual operation, effectively reducing the defect rate and improving the stability of the production process and the consistency of product quality.

[0015] 2. Through the adaptive design of core components such as the flattening position and nickel wire feeding and cutting module, this invention can be compatible with the production needs of resistors of various specifications. It breaks the limitations of traditional manual production or single-specification equipment with one material and one machine. A single machine has the production capacity of multiple specifications of products. This not only avoids the extra investment of enterprises to purchase equipment separately for different specifications of products, but also significantly improves the utilization rate of existing equipment, reduces the risk of idle fixed assets, and optimizes the enterprise's production cost structure.

[0016] 3. This invention adopts a servo motor-driven cam flattening method, combined with a fully automated process, which greatly improves flattening efficiency and stability, shortens the production cycle of a single product, and the production efficiency per unit time is much higher than that of manual operation, directly reducing the cost input per unit product. Fully automated production reduces the direct contact between operators and welding fumes and dust generated during the welding process, fundamentally reducing the harm of environmental pollution to human health, improving the production working environment, and ensuring the occupational health and safety of operators.

[0019] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0020] Example 1 according to Figure 1 , 2 As shown in 3, 4, 5, 6, and 7, this embodiment proposes a high-precision flattening and welding mechanism for nickel wire and substrate, including a base 1 and a substrate loading position 2, a carrier, a nickel wire feeding and cutting module 3, a substrate handling module 4, a nickel wire turntable 5, a flattening position 6, a welding position 7, a marking position 8, and a finished product unloading position 9 provided on the base 1. The substrate loading position 2 supplies the substrate, the substrate handling module 4 is used to deliver the substrate to the carrier, and the carrier is used to deliver the substrate to the welding position 7. The nickel wire turntable 5 is rotatable, and several pneumatic grippers 11 are provided at equal included angles on the nickel wire turntable 5. The nickel wire feeding and cutting module 3 is used to feed and cut the nickel wire. The pneumatic grippers 11 are used to hold the cut nickel wire and follow the rotation of the nickel wire turntable 5 to the flattening position 6 for flattening, and then to the welding position 7. The welding position 7 is used to weld the nickel wire and the substrate, and the welding position 7 is provided with a correction carrier and a correction guide position 10 to guide the welding position. After completion, the carrier resets the substrate, and the substrate transport module 4 sends the substrate to the marking position 8 for marking and then to the finished product unloading position 9. The substrate loading station 2 supplies the substrate to be processed to the equipment. The substrate handling module 4 moves the substrate to the carrier, and the carrier moves the substrate to the welding station 7 and positions it. At the same time, the nickel wire feeding and cutting module 3 feeds nickel wire and cuts it to a set length. The pneumatic grippers 11 set at equal angles on the nickel wire turntable 5 hold the cut nickel wire and, as the nickel wire turntable 5 rotates, sequentially transfers the nickel wire to the flattening station 6 for flattening. After flattening, it continues to be transferred to the welding station 7 with the nickel wire turntable 5. The correction guide station 10 at the welding station 7 guides and determines the welding position to ensure that the nickel wire and the substrate are accurately aligned. Then, the welding structure welds the two together. After welding, the carrier carries the substrate back to its original position, and the substrate handling module 4 moves again to transfer the substrate to the marking station 8 for marking. After marking, it is finally transferred to the finished product unloading station 9 to complete the processing flow of a single product.

[0021] The carrier includes a guide rail 12, a moving seat 13, and a carrier 14. The guide rail 12 is mounted on the base 1, and the moving seat 13 is movably mounted on the guide rail 12. The carrier 14 is connected to the moving seat 13 via a cylinder. The carrier 14 is used to carry the substrate. The guide rail 12 provides stable movement guidance for the moving seat 13. The moving seat 13 can move laterally along the guide rail 12 on the base 1 to realize the switching of the workstation of the carrier 14. The cylinder connected to the moving seat 13 can drive the carrier 14 to adjust its position, ensuring that the carrier 14 can accurately dock with the substrate handling module 4 to receive the substrate and accurately transport the substrate to the specified welding height and position of the welding station 7.

[0022] The substrate handling module 4 includes a first lead screw drive frame 15, a first movable seat 16, and a mounting frame 17. The first movable seat 16 is movably mounted on the first lead screw drive frame 15, and the mounting frame 17 is jacked up and down on the first movable seat 16. The mounting frame 17 is equipped with a handling frame 18, and the handling frame 18 is equipped with a suction nozzle 19 for adsorbing substrates. The first lead screw drive frame 15 drives the first movable seat 16 to move laterally along the drive frame through lead screw transmission, realizing the lateral switching of the handling frame 18 between the substrate loading position 2, the carrier, the marking position 8, and the finished product unloading position 9. The mounting frame 17 can be lifted up and down on the first movable seat 16 to adjust the height of the handling frame 18 and the suction nozzle 19. When moving to the target position, the mounting frame 17 lowers so that the suction nozzle 19 fits against the substrate surface, and the suction nozzle 19 generates negative pressure to adsorb the substrate. Then the mounting frame 17 rises and the first movable seat 16 moves to transfer the substrate to the next position. After that, the suction nozzle 19 releases the negative pressure and puts the substrate down, completing the substrate handling.

[0023] The welding position 7 includes a second lead screw drive frame 20, a second movable seat 21, and a welding module 22. The second movable seat 21 is movably mounted on the second lead screw drive frame 20, and the welding module 22 is vertically mounted on the second movable seat 21. The second lead screw drive frame 20 drives the second movable seat 21 to move laterally via lead screw transmission, thereby driving the welding module 22 to adjust its position within the lateral range of the welding position 7 to ensure alignment with welding points at different locations. The welding module 22 can move up and down on the second movable seat 21. After the nickel wire and the substrate are positioned at the welding position 7, the welding module 22 descends to the welding working height, and the welding function is activated to weld the nickel wire and the substrate. After welding is completed, the welding module 22 rises back to its original position, waiting for the next welding action.

[0024] The calibration guide position 10 includes a fixing frame 23 and a calibration probe 24. The fixing frame 23 is connected to one end of the front side of the second lead screw drive frame 20. The calibration probe 24 is mounted on the fixing frame 23, with its probe tip facing the welding position. The fixing frame 23 fixes the calibration probe 24 at a designated position on the front side of the second lead screw drive frame 20, ensuring that the probe tip of the calibration probe 24 is stably facing the welding area of ​​the welding position 7. Before the welding module 22 starts welding, the calibration probe 24 detects the relative position of the nickel wire and the substrate at the welding position and feeds back the position deviation signal to the control system. The control system adjusts the lateral position of the second moving seat 21 and the lifting height of the welding module 22 according to the feedback signal, ensuring that the welding module 22 is accurately aligned with the welding point, improving welding accuracy, and simultaneously driving the carrier to move and change the welding position of the substrate.

[0025] The nickel wire feeding and cutting module 3 includes a nickel wire spool 25, a guide wheel assembly 26, a straightening wheel assembly 27, a cleaning block 28, a feeding assembly, and a cutter 29. The nickel wire spool 25 is used to release the nickel wire, the feeding assembly is used to pull the nickel wire for conveying, the guide wheel assembly 26 is used to guide the nickel wire, the straightening wheel assembly 27 is used to straighten the nickel wire, the nickel wire passes through the cleaning block 28 for cleaning, and the cutter 29 is used to cut the nickel wire. Nickel wire coil 25 continuously releases nickel wire under the pulling force of the feeding group; guide wheel group 26 changes the conveying direction of nickel wire through the cooperation of multiple guide wheels, guiding the nickel wire to the set conveying path; straightening wheel group 27 clamps and limits the nickel wire with wheels set with continuous drop, ensuring that the nickel wire remains in a straight state during the conveying process and avoiding deviation and twisting; the nickel wire passes through cleaning block 28 during the conveying process, and the cleaning material inside the cleaning block 28 removes oil, dust and other impurities from the surface of the nickel wire; when the nickel wire is conveyed to the set length, the feeding group stops, the cutter 29 cuts the nickel wire, and after the cutting is completed, the feeding group restarts to convey the next section of nickel wire.

[0026] The feeding assembly includes a feeding wheel 30 and a support wheel 31. Nickel wire passes between the feeding wheel 30 and the support wheel 31. The feeding wheel 30 is driven to rotate by a motor. The motor drives the feeding wheel 30 to rotate at a set speed. The support wheel 31 provides support on the other side of the nickel wire, ensuring the nickel wire is tightly adhered to the wheel surface of the feeding wheel 30. When the feeding wheel 30 rotates, the friction between the wheel surface and the nickel wire propels the wire forward. By controlling the motor's speed and rotation time, the feeding speed and length of the nickel wire can be precisely controlled, ensuring accurate cutting by the subsequent cutter 29.

[0027] The flattening position 6 includes a fixed position 32, an adjusting support 33, and a supporting base 34. The adjusting support 33 is located on one side of the fixed position 32, and the supporting base 34 is located on the adjusting support 33. A pressing module 35 is elastically and movably installed above one side of the fixed position 32, and the lower end of the pressing module 35 is provided with a pressing block 36 that is adapted to the supporting base 34. A servo motor 37 is located above the fixed position 32, and the output end of the servo motor 37 is connected to a cam 38. The top of the pressing module 35 is provided with an adapter wheel 39 that is adapted to the cam 38. The fixed position 32 provides the mounting base for the various components of the flattening position 6; the adjustable support 33 can change the height and horizontal position of the support 34 through the adjustment structure, so that the support 34 can adapt to the flattening requirements of nickel wire of different specifications; the servo motor 37 drives the cam 38 to rotate at a set speed. During the rotation of the cam 38, its protruding part pushes the adapter wheel 39 on the top of the pressing module 35, so that the pressing module 35 overcomes the elastic force and moves downward. The pressure block 36 at the lower end of the pressing module 35 cooperates with the support 34 to squeeze and flatten the nickel wire located between the two; when the protruding part of the cam 38 rotates away from the adapter wheel 39, the pressing module 35 rises and resets under the action of elastic force, completing one flattening action. The precise control of the servo motor 37 can ensure the consistency of flattening force and size.

[0028] The marking position 8 includes a bracket 40, a transfer seat 41, and a marking frame 42. The transfer seat 41 is elliptical and mounted on one side of the bracket 40, and the marking frame 42 is movably mounted on the other side of the bracket 40. The marking frame 42 is provided with an adhesive head 43. The transfer seat 41 is used to support the substrate, and one end of the transfer seat 41 is provided with an ink pad 44 that is adapted to the adhesive head 43. The bracket 40 provides mounting support for the transfer station 41 and the marking frame 42. When the transfer station 41 receives the substrate transferred by the substrate handling module 4, the transfer station 41 adjusts its height according to the marking requirements to make the substrate at a suitable marking height. The marking frame 42 first moves laterally to above the ink pad 44 at one end of the transfer station 41. With the lifting and lowering of the transfer station 41, the glue head 43 dips into the ink pad 44. Then the marking frame 42 moves above the substrate. With the lifting and lowering of the transfer station 41, the glue head 43 marks the substrate at the designated position. After marking is completed, the marking frame 42 is reset, and the transfer station 41 waits for the substrate to be transferred to the next station.

[0029] Example 2 according to Figure 1 , 2As shown in 3, 4, 5, 6, and 7, this embodiment proposes a high-precision flattening and welding mechanism for nickel wire and substrate, including a base 1 and a substrate loading position 2, a carrier, a nickel wire feeding and cutting module 3, a substrate handling module 4, a nickel wire turntable 5, a flattening position 6, a welding position 7, a marking position 8, and a finished product unloading position 9 provided on the base 1. The substrate loading position 2 supplies the substrate, the substrate handling module 4 is used to deliver the substrate to the carrier, and the carrier is used to deliver the substrate to the welding position 7. The nickel wire turntable 5 is rotatable, and several pneumatic grippers 11 are provided at equal included angles on the nickel wire turntable 5. The nickel wire feeding and cutting module 3 is used to feed and cut the nickel wire. The pneumatic grippers 11 are used to hold the cut nickel wire and follow the rotation of the nickel wire turntable 5 to the flattening position 6 for flattening, and then to the welding position 7. The welding position 7 is used to weld the nickel wire and the substrate, and the welding position 7 is provided with a correction carrier and a correction guide position 10 to guide the welding position. After completion, the carrier resets the substrate, and the substrate transport module 4 sends the substrate to the marking position 8 for marking and then to the finished product unloading position 9. The substrate loading station 2 supplies the substrate to be processed to the equipment. The substrate handling module 4 moves the substrate to the carrier, and the carrier moves the substrate to the welding station 7 and positions it. At the same time, the nickel wire feeding and cutting module 3 feeds nickel wire and cuts it to a set length. The pneumatic grippers 11 set at equal angles on the nickel wire turntable 5 hold the cut nickel wire and, as the nickel wire turntable 5 rotates, sequentially transfers the nickel wire to the flattening station 6 for flattening. After flattening, it continues to be transferred to the welding station 7 with the nickel wire turntable 5. The correction guide station 10 at the welding station 7 guides and determines the welding position to ensure that the nickel wire and the substrate are accurately aligned. Then, the welding structure welds the two together. After welding, the carrier carries the substrate back to its original position, and the substrate handling module 4 moves again to transfer the substrate to the marking station 8 for marking. After marking, it is finally transferred to the finished product unloading station 9 to complete the processing flow of a single product.

[0030] A multi-axis drive module 45 is provided on one side above the base 1. The finished product unloading position 9 is located on the multi-axis drive module 45, and the multi-axis drive module 45 is used to drive the finished product unloading position 9 to move laterally and longitudinally. The multi-axis drive module 45 receives instructions from the control system and can drive the finished product unloading position 9 to move laterally and longitudinally respectively. After the substrate handling module 4 places the marked finished product on the finished product unloading position 9, the multi-axis drive module 45 drives the finished product unloading position 9 to move laterally to the designated unloading area according to the set unloading path, and then adjusts the placement position of the finished product by moving longitudinally, so as to realize the orderly unloading and placement of the finished product, which facilitates the subsequent collection and transfer of finished products.

[0031] This high-precision flattening and welding mechanism for nickel wire and substrates, through the automation of its substrate loading station 2, substrate handling module 4, flattening station 6, welding station 7, and finished product unloading station 9, achieves fully automated operation from material loading, nickel wire flattening, substrate welding to finished product unloading. It completely replaces manual loading and unloading and manual transfer processes, significantly reducing labor input and avoiding material positioning deviations and collisions caused by subjective factors in manual operation. This effectively reduces the defect rate and improves the stability of the production process and the consistency of product quality. Furthermore, through the adaptive design of core components such as the flattening station 6 and the nickel wire feeding and cutting module 3, this invention can accommodate the production needs of resistors of various specifications, breaking the limitations of traditional manual production or single-specification equipment with one material per machine. A single machine can produce multiple specifications of products, avoiding the additional investment of enterprises in purchasing separate equipment for different specifications, significantly improving the utilization rate of existing equipment, reducing the risk of idle fixed assets, and optimizing the enterprise's production cost structure. Meanwhile, this invention employs a flattening method where a servo motor 37 drives a cam 38, combined with a fully automated process, which significantly improves flattening efficiency and stability, shortens the production cycle of a single product, and increases production efficiency per unit time far beyond manual operation. This directly reduces the cost of a single product. Fully automated production also reduces direct contact between operators and welding fumes and dust generated during the welding process, thereby reducing the harm of environmental pollution to human health from the source, improving the production environment, and ensuring the occupational health and safety of operators.
