Description

Technical Field

[0001] This invention relates to a dual-circuit board soldering switch device for an electric mosquito repellent device. Background Technology

[0002] Currently, in the assembly and soldering production of circuit boards and switches, most scenarios still rely on manual operation or single-station semi-automatic equipment processing. Manual labor involves sequentially completing the processes of circuit board loading, two switch alignment and installation, manual spot welding, and finished product unloading. Some semi-automatic equipment only supports single-station soldering operations, requiring the loading and soldering of two switches in stages. This results in long process flow waiting times and low overall equipment efficiency. Furthermore, manual positioning accuracy is unstable, easily leading to switch misalignment and omissions. Precise control of manual solder feeding is difficult, resulting in defects such as cold solder joints and uneven solder points, leading to poor product consistency. Simultaneously, single-station operations cannot perform each process in parallel, resulting in low production efficiency, high labor costs, and difficulty meeting the needs of large-scale continuous production. Moreover, the lack of a pre-processing omission detection step allows missing parts to easily enter the soldering process, causing material waste and time losses. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a dual-circuit board welding switch device for electric mosquito coils. It has a reasonable structural layout, stable and reliable operation, effectively improves the efficiency of circuit board spot welding, and has good performance.

[0004] To achieve the above objectives, the present invention provides a dual-circuit board welding switch device for an electric mosquito coil, comprising a frame, a turntable and a rotary motor for driving the turntable to rotate, a plurality of support units for accommodating circuit boards arranged circumferentially on the turntable, each support unit having at least two support slots, a feeding mechanism, an assembly mechanism, a spot welding mechanism and an unloading mechanism arranged circumferentially on the frame, the assembly mechanism including an assembly machine corresponding to the number of support slots, the assembly machine being used to assemble switches for the corresponding support slots, the spot welding mechanism including a spot welding machine corresponding to the number of support slots, the spot welding machine being used to spot weld switches for the corresponding support slots, the feeding mechanism including a feeding machine and a feeding rail corresponding to the number of support slots, the feeding rail being used to feed the circuit boards, the feeding machine including a feeding frame, a first lifting cylinder and a first translating cylinder, the feeding frame having a feeding rail arranged radially along the turntable, the first lifting cylinder slidingly engaging with the feeding rail, the first translating cylinder... The output end of the shifting cylinder is connected to the first lifting cylinder to drive the first lifting cylinder to slide on the feeding rail. The output end of the first lifting cylinder is connected to a number of feeding suction cups corresponding to the bearing slots. The feeding suction cups are used to adsorb and grab the circuit board and send it to the corresponding bearing slot. The unloading mechanism includes an unloading rail and an unloading machine. The unloading rail is inclined. One end of the unloading rail is close to the edge of the turntable, and the other end is connected to a collection slot. The unloading machine includes an unloading frame, a second lifting cylinder, and a second translation cylinder. The unloading frame is provided with an unloading rail radially along the turntable. The second lifting cylinder slides on the unloading rail. The output end of the second translation cylinder is connected to the second lifting cylinder to drive the second lifting cylinder to slide on the unloading rail. The output end of the second lifting cylinder is connected to a number of unloading claws corresponding to the bearing slots. The unloading claws are used to clamp the side wall of the circuit board and send the circuit board to the unloading rail. The bearing unit is provided with a clamping slot on the side wall of the bearing slot for the unloading claws to insert into.

[0005] The advantages of this setup are as follows: Multiple support slots are set on a single support unit, and assembly and spot welding machines are matched one-to-one with the number of support slots. From an overall architectural perspective, this achieves a streamlined processing system for simultaneous assembly and spot welding of multiple workpieces, effectively reducing the processing cycle time of a single circuit board and significantly improving the overall production efficiency of the equipment. Compared to traditional turntable equipment with a single support slot and a single processing head, in this structure, each station can simultaneously perform corresponding process operations on multiple circuit boards after each indexing rotation of the turntable: the assembly station can simultaneously assemble switches for circuit boards in multiple support slots, and the spot welding station can simultaneously complete the switch spot welding operations for multiple circuit boards. Each process proceeds in parallel without step-by-step waiting time, and the processing capacity per unit time increases synchronously with the number of support slots, fully adapting to the needs of large-scale continuous production. The feeding mechanism employs multiple sets of feeding suction cups matching the number of carrier slots, with the suction cup spacing corresponding to the carrier slot spacing. A single lifting and lateral movement can simultaneously and precisely pick up and place multiple circuit boards, eliminating the need for repeated pick-up and place-down operations. This significantly simplifies the feeding logic, reduces the number of cylinder reciprocating strokes, shortens the feeding station's cycle time, and lowers the frequency of wear and tear on moving components. Furthermore, the suction cup-type pick-up and place-down mechanism uses flexible contact, avoiding pressure damage and scratches to the circuit board surface and components caused by rigid clamping, ensuring high feeding yield. The unloading mechanism uses unloading claws that correspond one-to-one with the carrier slots, with precise claw spacing matching the carrier slot spacing. A single action can simultaneously pick up multiple finished circuit boards and transfer them to the unloading rail for unloading. The pick-up and place-down actions are continuous and efficient, corresponding to the feeding station's cycle time and highly synchronized with the rotary table's indexing rhythm. The sidewall of the bearing tank is equipped with clamping slots for the grippers to insert and pick up materials. The clamping points are stable and reliable, avoiding solder joints and components on the circuit board, preventing damage to the formed solder joints during unloading, and ensuring the quality of the finished product. The entire equipment adopts a streamlined cyclical operation logic. The functional stations for loading, assembly, inspection, spot welding, and unloading are arranged in an orderly manner along the circumference of the turntable. The workpieces complete all processes sequentially as the turntable rotates. The action path is simple and clear, the equipment control logic is simple, and the operation is stable and reliable. The fully automated operation reduces manual intervention, improves production efficiency, effectively reduces labor costs and human operation errors, and ensures product processing consistency.

[0006] As a further feature of the present invention, a feed rail for feeding a switch is provided on the frame along the radial direction of the turntable at the position corresponding to the assembly machine position. The assembly machine includes an assembly frame, a third lifting cylinder, and a third translation cylinder. The assembly rail is arranged radially along the turntable on the assembly frame. The third lifting cylinder is slidably fitted on the assembly rail. The output end of the third translation cylinder is connected to the third lifting cylinder to drive the third lifting cylinder to slide on the assembly rail. The output end of the third lifting cylinder is connected to an assembly gripper, which is used to grab the switch and send it to the corresponding bearing groove.

[0007] The advantages of this design are as follows: the radial feeding of switch materials along the turntable allows for continuous conveying of materials, and the staggered front-end structure enables orderly separation of individual materials, ensuring a stable feeding rhythm and preventing material stacking or jamming, thus providing a stable material foundation for continuous assembly. The Cartesian coordinate drive structure, composed of the third translation cylinder and the third lifting cylinder, operates on a linear reciprocating path, offering precise stroke control, fast response, and a fixed and controllable trajectory. This allows for accurate transfer of the switch to the preset assembly position in the corresponding bearing slot, achieving a much higher assembly positioning accuracy than manual operation. This ensures precise alignment of the switch pins with the circuit board pads, providing a pre-emptive guarantee for the quality of solder joints in subsequent welding processes. The assembly grippers are designed specifically for the switch's shape, providing uniform clamping force and preventing deformation of the switch housing or bending of the pins, effectively reducing material loss during assembly. Furthermore, the modular design of each assembly machine, with independent drive and operation, allows for individual shutdown and maintenance in case of a single assembly mechanism failure without affecting the normal operation of other workstations, minimizing the impact of equipment downtime on overall production capacity.

[0008] As a further feature of the present invention, the spot welding machine includes a spot welding frame, a welding torch, and a drive cylinder. The spot welding frame is provided with an arc-shaped groove, and a welding torch holder is slidably fitted in the arc-shaped groove. The welding torch is slidably mounted on the welding torch holder. A material tube for feeding solder is also connected to the welding torch. The output end of the drive cylinder is connected to the tail of the welding torch, and the drive cylinder is mounted on the welding torch holder.

[0009] The advantages of this design are as follows: Using a spot welding frame with an arc-shaped groove in conjunction with a sliding welding torch holder, along with a drive cylinder and solder feed tube, significantly improves the adaptability of the welding structure while ensuring welding stability. Traditional fixed welding torches have non-adjustable welding angles, only suitable for the solder joint height and pin tilt angle of a single circuit board specification. When changing products, the entire welding module needs to be replaced, resulting in high debugging costs and long cycles. In contrast, the welding torch holder in this structure can slide and lock along the arc-shaped groove, allowing flexible adjustment of the welding torch's pitch angle to adapt to solder joints of different heights and switch pins of different tilt angles. Without replacing core welding components, it can cover the welding needs of multiple product specifications, significantly shortening product changeover debugging time and improving equipment uptime. The drive cylinder directly pushes the welding torch to the welding station. The controllable cylinder stroke ensures uniform pressure from the welding head on the solder joint, preventing excessive pressure from damaging components or deforming pins, and preventing insufficient pressure from causing poor welding contact and resulting in cold solder joints or false solder joints. When used with a solder feed tube, it enables quantitative solder feeding, which can precisely control the amount of solder wire used in each solder joint, ensuring uniform solder joint fullness. It effectively reduces problems such as solder bridging and solder ball splashing caused by excessive solder, as well as cold solder joints and insufficient solder joint strength caused by insufficient solder, thus greatly improving the soldering yield and the reliability of product electrical connections.

[0010] As a further feature of the present invention, a first feed tube arm is connected to the welding torch, and a second feed tube arm is oscillatingly connected to the other end of the feed tube arm. A spherical cavity is provided at the other end of the second feed tube arm, and a ball head is connected to the feed tube. The ball head rotates and fits in the spherical cavity.

[0011] The advantages of this design are as follows: Traditional solder feed tubes are mostly rigidly fixed connections, allowing only position adjustment in a single direction with a very limited angle adjustment range. When the soldering gun angle is adjusted or the solder joint position changes, the solder feed nozzle is difficult to precisely align with the contact area between the solder head and the pin, easily leading to solder feed position deviation. This results in insufficient solder wire melting, poor solder joint wetting, and consequently, defects such as cold solder joints and uneven soldering. This structure achieves planar position adjustment of the solder feed end through the swing of the two-stage feed tube arm. Combined with the omnidirectional rotation of the ball head within the spherical cavity, it enables three-dimensional adjustment of the solder feed nozzle's solder ejection angle. This ensures that the solder ejection end is always precisely aligned with the optimal soldering point between the soldering iron tip and the workpiece pin, guaranteeing that the solder wire evenly wets the solder pad and pin after melting, improving the solder joint's welding strength and electrical performance. Simultaneously, this adjustable structure can adapt to solder feed position calibration after soldering gun angle adjustment, complementing the arc-groove angle-adjusting soldering gun structure, further enhancing the equipment's adaptability to different products. In addition, the locking structure between the ball head and the spherical cavity ensures stable positioning, preventing solder feeding position deviation even during long-term high-speed operation, reducing the frequency of daily inspection and calibration, and lowering maintenance workload. This structure can also accommodate solder wires of different diameters, and the material tube replacement operation is simple, meeting the solder feeding needs of different solder joint sizes. It is especially suitable for circuit board processing scenarios with small pin pitch and precise solder joints, effectively avoiding problems such as solder bridging and solder dross contaminating adjacent components, thus expanding the precision processing application scenarios of the equipment.

[0012] As a further feature of the present invention, a testing frame is provided on the frame between the assembly mechanism and the spot welding mechanism. The testing frame is provided with a testing slot, and a plurality of identification probes for identifying switches on the circuit board are provided in the testing slot. The number of identification probes matches the number of bearing slots. The identification probes slide in conjunction with the testing slot. A fastening wing plate is provided on the side wall of the identification probe, and a fastening screw for fastening the identification probe is provided between the fastening wing plate and the outer wall of the testing slot.

[0013] The advantages of this design are as follows: An adjustable detection mechanism between the assembly and spot welding mechanisms enables pre-assembly detection of the switch assembly status, preventing missing parts from flowing into the welding process. Pre-welding detection of assembly defects such as missing parts and misalignments allows for direct interception of defective parts, avoiding ineffective welding of missing parts. This saves solder and welding time, and prevents material waste caused by the difficulty of rework and direct scrapping of missing parts after welding, effectively reducing production losses and manufacturing costs. The detection rack features long detection slots, along which multiple identification probes can slide and adjust their positions, secured by fastening wing plates and screws. This structure allows for flexible adjustment of the probe spacing based on the carrier slot spacing and switch size, adapting to the testing needs of different product specifications without replacing the detection rack itself. This significantly reduces testing modification costs during product changeovers, and debugging is simple and quick. Multiple sets of identification probes, matching the number of carrier slots, perform synchronous detection, with the detection cycle perfectly matching the turntable rotation rhythm, eliminating the need for additional detection dwell time and not affecting the overall equipment capacity. In addition, the identification probe can use photoelectric or capacitive proximity sensors, which have fast response speed, high detection accuracy, and good adaptability to dust, temperature and humidity environments in industrial sites, and stable and reliable operation. The design of the fastening wing plate increases the contact area when locking, and the probe is not easy to shift position after locking. It can maintain detection accuracy even after long-term operation and reduce false judgments and missed judgments.

[0014] As a further feature of the present invention, a rotating shaft is provided on the frame, and the turntable is rotatably connected to the rotating shaft. The bearing groove on the bearing unit is arranged radially along the turntable. A material picking mechanism is also provided on the frame between the spot welding mechanism and the unloading mechanism. The material picking mechanism includes a material picking seat, a material picking frame, and a material picking cylinder. The material picking frame is connected to the rotating shaft, and a material picking rail is arranged radially along the turntable on the material picking frame. A fourth lifting cylinder is slidably arranged on the material picking rail. The output end of the material picking cylinder is drivenly connected to the fourth lifting cylinder to drive the fourth lifting cylinder to slide on the material picking rail. A switch gripper is connected to the output end of the fourth lifting cylinder. The switch gripper is used to hold the switch on the circuit board.

[0015] The advantages of this setup are: A material handling mechanism is added between the spot welding mechanism and the unloading mechanism, serving as the main discharge channel for good workpieces by clamping the switch body. This, together with the rear-mounted plate clamping and unloading mechanism, forms a dual discharge mechanism, balancing discharge efficiency and compatibility with abnormal operating conditions. The material handling rack is integrated and installed on the turntable shaft, with material handling rails arranged radially along the turntable. Combined with a two-axis drive structure consisting of a fourth lifting cylinder and a material handling cylinder, it realizes the lifting, picking, and radial movement of the switch grippers. The overall motion path is simple and clear, the alignment accuracy is controllable, and the operating cycle perfectly matches the turntable's indexing rotation, without additional time spent on station workflow. For finished, welded workpieces, the switch grippers directly hold the switch body for material removal. The gripping points completely avoid the circuit board surface and the hot solder joints, ensuring a secure grip without scratching the precision components or damaging the still-cooled solder joint surfaces. This effectively protects the finished product's appearance and electrical connection reliability, making it particularly suitable for circuit board processing scenarios with dense components and high solder joint precision requirements. When workpieces have issues such as missing switches or solder misalignment that prevent the grippers from holding them effectively, the workpiece can continue to rotate with the turntable to the subsequent unloading station. The unloading mechanism then uses the circuit board body as a clamp to remove the workpiece, preventing jams and equipment downtime caused by defective workpieces remaining on the turntable. This significantly improves the equipment's fault tolerance and continuous operation stability. This allows good products to be discharged quickly through a dedicated channel, while defective workpieces are discharged through a general channel. The two processes do not interfere with each other, ensuring the discharge efficiency of good products and eliminating the need for additional dedicated rejection stations. This simplifies the layout of the turntable and effectively improves the space utilization of the equipment.

[0016] As a further feature of the present invention, a material collection rail is provided on the frame corresponding to the material picking mechanism, one end of the material collection rail is located next to the turntable, and the other end is connected to a material collection trough.

[0017] The advantages of this setup are: A corresponding material collection rail and trough are provided for the material handling mechanism, forming a dedicated collection channel for good-quality workpieces. This enables automatic and orderly collection of finished products, perfecting the entire automated material handling and discharging process. Good-quality circuit boards retrieved by the material handling mechanism can be directly fed into the material collection rail inlet. Utilizing the inclined design of the rail, the workpieces slide smoothly down the rail under their own weight to the collection trough at the end for centralized storage. No additional power drive device is required throughout the process. The structure is simple and reliable, with low energy consumption and no additional operating cycle time, efficiently matching the discharging rhythm of the material handling mechanism.

[0018] As a further feature of the present invention, the switch gripper includes a gripper base and two gripper arms, the two gripper arms being slidably disposed on the gripper base. The gripper base is also provided with a gripping spring for driving the two gripper arms to close. A gripping groove is formed between the two gripper arms, and the opening of the gripping groove is configured as a flared mouth. The frame is provided with a baffle plate on the edge of the turntable for blocking the circuit board from falling into the collection rail when the material picking cylinder retracts. The baffle plate is disposed on the movement path of the switch gripper. The frame is also provided with a blocking cylinder for driving the baffle plate to expose or block the movement path of the circuit board on the switch gripper.

[0019] The advantages of this design are as follows: The switch grippers employ a spring-driven double-arm clamping structure, providing moderate and flexible clamping force to stably hold the switch body, avoiding damage to the switch housing and pin deformation caused by rigid clamping. It also accommodates switches of different specifications within a certain size range, enhancing versatility. The clamping slot opening uses a flared guide design, automatically correcting minor positional deviations during material handling and reducing alignment accuracy requirements, effectively improving the success rate of material handling and minimizing handling failures due to alignment errors. Material removal utilizes a mechanical stop-and-go baffle. When the grippers retract, the baffle blocks the circuit board, automatically detaching the workpiece from the grippers. This eliminates the need for a separate release drive element at the gripper end, simplifying the pneumatic and structural design of the gripper area, reducing pneumatic component failure points, improving operational reliability, and providing a fast material removal response to adapt to high-speed discharge cycles.

[0020] As a further feature of the present invention, the baffle plate is inclined.

[0021] The beneficial effects of this design are as follows: Setting the baffle plate in an inclined position provides a guiding and buffering effect during the unloading process, further improving the stability and reliability of finished product output. The inclined guiding method effectively buffers the impact of the falling workpiece, reducing the impact on circuit board components and solder joints, protecting the electrical performance and appearance quality of the finished product, and is especially suitable for circuit board products containing precision components. Furthermore, the inclined baffle plate is easy to process, install, and debug; the optimal inclination angle can be adapted according to the workpiece weight and size, balancing unloading reliability and unloading stability; a wear-resistant buffer pad can also be added to the plate surface to further reduce impact noise, reduce surface wear, extend component lifespan, and optimize the on-site working environment.
