Description

Technical Field

[0001] This utility model relates to the field of surface mount inductor manufacturing technology, and in particular to a ring conveying machine for preparing inductor coil assemblies. Background Technology

[0002] In the field of electronic component manufacturing, surface mount inductors are key basic components in consumer electronics, industrial control, and new energy, and their performance stability and operational reliability directly determine the operational quality of end devices. The production quality of surface mount inductors largely depends on the manufacturing precision of their semi-finished products—inductor coil assemblies. Among them, the leadboard, as the core load-bearing structure of the inductor coil assembly, needs to achieve precise positioning, fixing, and assembly of multiple inductor coils. The assembly precision and processing consistency of the leadboard with the inductor coils are key prerequisites for ensuring that the electrical parameters of the subsequent surface mount inductors meet the standards.

[0003] As electronic devices become increasingly miniaturized and highly integrated, higher demands are placed on the production efficiency and processing precision of inductor coil assemblies. This also places more stringent requirements on the production and conveying equipment for inductor coil assemblies. Currently, in the automated production process of inductor coil assemblies, the industry commonly uses linear conveyor lines as the core conveying carrier. This involves the sequential arrangement of lead sheet loading, inductor coil loading, spot welding and bonding, cutting and shaping, visual inspection, and finished product unloading of the inductor coil assemblies—a complete processing flow. However, existing linear conveyor lines have problems in practical applications, specifically: 1) Since each workstation is distributed along a straight line, the overall length of the conveyor line needs to be greatly extended in order to ensure that each workstation has sufficient operating space and equipment installation space, resulting in a large factory floor area required for linear conveyor lines, which seriously restricts the flexibility of production layout; 2) The workstations are distributed along a straight line, which not only requires workshop workers to travel back and forth over a long distance for inspection and operation, but also makes it difficult to centrally control the production process.

[0004] Therefore, it is urgent for technical personnel to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a ring conveying machine for manufacturing inductor coil assemblies, which aims to solve the problems of large footprint, weak adaptability to workshop space, and inconvenient management caused by the dispersed workstations in the existing design of conveying equipment.

[0009] As a further improvement to the technical solution disclosed in this utility model, the circular conveyor for preparing the positioning fixture of the inductor coil assembly also includes multiple station positioning components; when the follower seat moves with the chain-type circular conveyor to any of the following stations: wire plate loading station, inductor coil loading station, spot welding and fixing station, cutting and shaping station, visual inspection station, and finished product unloading station, the corresponding station positioning component calibrates the position of the follower seat.

[0010] As a further improvement to the technical solution disclosed in this utility model, the workstation positioning component includes a sensing element and a slotted photoelectric sensor; the sensing element is fixedly installed on the bottom of the accompanying seat; the slotted photoelectric sensor is fixedly installed on the chain ring conveyor and is arranged at the preset positions corresponding to the wire plate feeding station, the inductor coil feeding station, the spot welding and fixing station, the cutting and shaping station, the visual inspection station, and the finished product unloading station.

[0011] As a further improvement to the technical solution disclosed in this utility model, the circular conveying machine for preparing the positioning fixture of the inductor coil assembly also includes a stripping mechanism; the stripping mechanism is arranged on one side of the chain circular conveyor and is set at a preset position of the finished product stripping station, which is used to lift and remove the finished inductor coil assembly from the positioning fixture.

Furthermore, the positioning fixture and accompanying base adopt a detachable assembly structure. When production requirements involve different specifications of lead sheets or inductor coils, only the positioning fixture of matching size needs to be replaced, thus significantly shortening the equipment adjustment cycle.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 , Figure 2 Two different perspectives of the circular conveyor mechanism for preparing inductor coil assemblies disclosed in this utility model are shown. It can be seen that, along the clockwise flow direction, the machine sequentially arranges the wire board loading station, the inductor coil loading station, the spot welding and fixing station, the cutting and shaping station, the visual inspection station, and the finished product unloading station, which together form a closed-loop processing flow channel. Its core function is to realize the fully automated conveying and processing of inductor coil assemblies from raw material loading to finished product unloading, providing a stable carrier for precise operation at each station. like Figures 1-3 As shown, the circular conveyor for preparing inductor coil assemblies mainly consists of a chain conveyor 1, a traveling seat 2, a positioning fixture 3, a station positioning component 4, and a unloading mechanism 5. The chain conveyor 1 is arranged along the path of a closed-loop processing flow channel to provide clockwise cyclic conveying power, providing a foundation for the stable flow of the traveling seat 2 and the positioning fixture 3. Multiple traveling seats 2 are carried by the chain conveyor 1, spaced apart along its conveying direction and fixedly connected to the chain conveyor 1, and are used to support the positioning fixture 3. The positioning fixture 3 is detachably assembled onto the traveling seat 2, and its top wall is simultaneously formed with a plate positioning groove 31 for placing the conductor board and a coil positioning groove 32 for placing the inductor coil (e.g., ...). Figure 6As shown in the figure, this is to achieve precise positioning of the conductor board and multiple inductor coils. like Figure 4 As shown, the chain-type circular conveyor 1 includes a frame 11, a circular conveyor chain 12, a drive sprocket 13, a driven sprocket 14, and a motor drive unit 15. The frame 11 extends along the path of the closed-loop processing flow channel, serving as the overall support foundation for the chain-type circular conveyor 1. The drive sprocket 13 and the driven sprocket 14 are respectively mounted at both ends of the frame 11, and the two are connected by the circular conveyor chain 12. The closed-loop design of the circular conveyor chain 12 is adapted to the processing flow channel, enabling continuous material flow. The motor drive unit 15 is fixedly mounted on the frame 11, and its power output end is connected to the drive sprocket 13, providing power to the entire conveying system. Furthermore, the motor drive unit 15 includes a rotary motor 151 and a torque limiter 152. The output shaft of the rotary motor 151 is connected to the input end of the torque limiter 152, while the output end of the torque limiter 152 is connected to the drive sprocket 13. In this way, when the equipment is overloaded (such as the ring conveyor chain 12 jamming or the load exceeding the preset range), the power transmission can be cut off in time, effectively preventing core components such as the rotary motor 151 and the drive sprocket 13 from being damaged due to overload, which helps to reduce the later maintenance costs. As Figure 1 , Figure 2 As shown, multiple station positioning components 4 are provided, corresponding to the conductor board loading station, inductor coil loading station, spot welding and fixing station, cutting and shaping station, visual inspection station, and finished product unloading station, respectively. Figure 3 As shown, the station positioning component 4 includes a sensor 41 and a slotted photoelectric sensor 42. The sensor 41 is fixedly installed at the bottom of the traveling seat 2 and rotates synchronously with the traveling seat 2; the slotted photoelectric sensor 42 is fixedly installed on the frame 11 of the chain conveyor 1, and is arranged at the preset position corresponding to each station, with its detection slot facing the flow path of the traveling seat 2. When the traveling seat 2 moves to any station with the circular conveyor chain 12, the sensor 41 extends into the detection slot of the corresponding slotted photoelectric sensor 42, triggering the station positioning component 4 to calibrate the position of the traveling seat 2, ensuring that the positioning fixture 3 is accurately aligned with the operating mechanism of each station.

[0023] like Figure 1 As shown, the unloading mechanism 5 is arranged on one side of the chain conveyor 1 and positioned at a preset location in the finished product unloading station, used to lift and unload the finished inductor coil assembly from the positioning fixture 3. Figure 5As shown, the unloading mechanism 5 mainly consists of a support frame 51, a cylinder 52, a support seat 53, and multiple unloading needles 54. The support frame 51 is fixedly mounted on the ground on one side of the chain conveyor 1 to provide installation support; the cylinder 52 is fixedly mounted on the support frame 51, and its output end is connected to the support seat 53 for driving the support seat 53 to perform lifting movements; multiple unloading needles 54 are fixedly mounted on the top of the support seat 53, and their relative positions are adapted to the plate positioning groove 31 of the positioning fixture 3, which can collaboratively push the finished inductor coil assembly. It should also be noted that, thanks to the detachable assembly structure of the positioning fixture 3 and the accompanying seat 2, when production needs involve different specifications of lead sheets or inductor coils, only the positioning fixture 3 of the matching size needs to be replaced, thereby significantly shortening the equipment adjustment cycle; furthermore, the closed-loop processing flow channel design and the cooperation of the station positioning component 4 not only ensure the operating accuracy of each station, but also lay a good foundation for improving production efficiency.

[0024] The working principle of the circular conveyor for preparing inductor coil assemblies is roughly as follows: During equipment operation, the rotary motor 151 starts and transmits power to the drive sprocket 13 via the torque limiter 152, driving the circular conveyor chain 12 to rotate clockwise. The follower seat 2 moves synchronously with the circular conveyor chain 12. When the positioning fixture 3 moves with the follower seat 2 to the lead plate loading station, the station positioning component 4 calibrates and positions the lead plate to the plate positioning groove 31. Then it flows to the inductor coil loading station, and similarly completes the loading of multiple inductor coils to the coil positioning groove 32. It continues to flow to the spot welding and bonding station to complete the component spot welding, the cutting and shaping station to complete the cutting and shaping, the visual inspection station to complete the quality inspection, and finally reaches the finished product unloading station. At this time, the cylinder 52 drives the support seat 53 to rise, which in turn drives the stripping needle 54 to extend into the plate positioning groove 31 of the positioning fixture 3, lifting and removing the finished inductor coil assembly; after stripping is completed, the positioning fixture 3 continues to flow along the closed loop channel with the following seat 2, entering the next cycle. The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
