Description

Technical Field

[0001] This utility model relates to the field of surface mount inductor manufacturing technology, and in particular to a post-processing assembly equipment for inductor coil components. Background Technology

[0002] In the field of electronic component manufacturing, surface mount inductors, as core finished components that realize functions such as electromagnetic induction and energy conversion, directly depend on the processing quality of upstream inductor coil assemblies for their performance stability and service life. With the continuous growth of downstream industries' demand for surface mount inductors and the rapid iteration of products towards miniaturization and high precision, the post-processing stage of inductor coil assemblies, as a key process connecting semi-finished products and finished surface mount inductors, has seen its processing efficiency and precision become core factors restricting the efficiency of finished product production.

[0003] Specifically, after the inductor coil assembly is soldered and formed, it needs to undergo post-processing steps such as cutting excessively long wires and transferring semi-finished products. Currently, although the post-processing stage has fully adopted an automated production model, its operating mechanism still has significant technical defects, specifically reflected in: 1) Although the blanking, cutting and placement of inductor coil components are all completed by automated equipment, the material transfer between processes needs to be performed separately by dedicated handling modules (such as mechanical grippers and conveyor belts), which results in a significant time difference between process connections. This directly leads to an extension of the overall processing cycle and makes it difficult to meet the high-efficiency requirements of large-scale continuous production of surface mount inductors. More importantly, during the multi-stage transfer process, the inductor coil components are prone to positional shifts at the docking points of different handling modules. Subsequent processes need to invest additional time in positioning and correction, further reducing production efficiency and increasing the risk of damage to semi-finished products. 2) In the existing post-processing process, the feeding machine, cutting machine and the container tooling are all arranged independently. Sufficient material transfer channels and maintenance space need to be reserved, which significantly increases the overall floor area of ​​the production line and seriously limits the production line's capacity expansion potential.

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

[0005] The purpose of this utility model is to provide a post-processing assembly equipment for inductor coil components, which aims to solve the problems in the existing design, such as the need for dedicated handling modules to transfer materials between processes, resulting in long processing cycles due to connection time differences, the risk of component displacement due to multi-stage transfer, and the large footprint of independently arranged equipment.

[0006] This utility model relates to a post-processing assembly for inductor coil components, including a material feeding and conveying machine, a cutting machine, and a housing unit; The material handling and transfer machinery is used to receive inductor coil assemblies that have been welded and formed, and has the freedom of movement along a preset trajectory; The cutting machine is arranged to correspond to the movement trajectory of the material transfer machine, and its cutting end is adapted to the position of the excessively long wire to be cut on the inductor coil assembly; when the material transfer machine drives the inductor coil assembly to move along the preset trajectory to the cutting machine, the cutting machine performs the cutting action. The housing unit is located at the end of the material handling and transfer machinery's movement trajectory and is used to house the inductor coil assembly after the wires have been cut.

[0007] As a further improvement to the technical solution disclosed in this utility model, the unloading and transfer machinery includes a transverse drive unit, a first picking mechanical arm and a second picking mechanical arm; both the first picking mechanical arm and the second picking mechanical arm have lifting functions, are connected to the transverse drive unit in a transmission, and synchronously perform transverse movement under the driving force of the transverse drive unit. The first picking robot arm is used to pick up the welded inductor coil assembly at the unloading station by lifting and moving it laterally to the cutting machine's operating area; the second picking robot arm is used to pick up the cut inductor coil assembly by lifting and moving it to the receiving unit after the cutting machine has finished cutting.

[0008] As a further improvement to the technical solution disclosed in this utility model, the first picking robotic arm includes a first linear drive actuator, a first support frame, and a first vacuum adsorption assembly; the first linear drive actuator is loaded by a transverse drive unit, and its output end is fixedly connected to the first support frame; the first vacuum adsorption assembly uses the first support frame as a mounting base and is used to adsorb the inductor coil assembly formed by welding through negative pressure; the second picking robotic arm includes a second linear drive actuator, a second support frame, and a second vacuum adsorption assembly; the second linear drive actuator is also loaded by a transverse drive unit, and its output end is fixedly connected to the second support frame; the second vacuum adsorption assembly uses the second support frame as a mounting base and is used to adsorb the inductor coil assembly after wire cutting through negative pressure.

[0009] As a further improvement to the technical solution disclosed in this utility model, the transverse drive unit is preferably a linear motor module, and the first linear drive actuator and the second linear drive actuator are both preferably any one of a cylinder, a hydraulic cylinder and a linear motor.

[0010] As a further improvement to the technical solution disclosed in this utility model, the accommodating unit includes a first accommodating fixture and a second accommodating fixture; the first accommodating fixture and the second accommodating fixture are arranged sequentially along the preset trajectory of the unloading and transfer machinery; both the first accommodating fixture and the second accommodating fixture are used to accommodate the inductor coil assembly after the wire cutting is completed, and cooperate with the unloading and transfer machinery to realize the alternating accommodating of the inductor coil assembly.

[0011] As a further improvement to the technical solution disclosed in this utility model, the inductor coil assembly post-processing assembly also includes a laser displacement sensor and a waste bin; the laser displacement sensor is set directly opposite the inductor coil assembly unloading station and is used to monitor the welding and forming quality of the inductor coil assembly; the waste bin is arranged corresponding to the movement trajectory of the unloading and transfer machinery and is located in the upstream area of ​​the cutting machinery, and is used to collect inductor coil assemblies that are determined to be unqualified by monitoring.

[0012] In practical applications, the inductor coil assembly post-processing combination equipment disclosed in this utility model can achieve at least the following beneficial technical effects, specifically: 1) The material handling and transfer machinery not only receives semi-finished products, but also, with its freedom of movement along a preset trajectory, drives the inductor coil assembly through the entire process of transfer from the material receiving point to the cutting machine and then to the storage unit. This eliminates the need for multi-stage transfers using dedicated handling modules, fundamentally eliminating waiting time differences between processes and significantly shortening the overall processing cycle. Furthermore, the inductor coil assembly is transferred entirely by the same material handling and transfer machinery, avoiding potential positional offsets that may occur when different handling modules are connected. This eliminates the need for subsequent positioning corrections, effectively improving production efficiency and minimizing the risk of damage to semi-finished products during transfer. 2) The cutting machine is arranged in accordance with the movement trajectory of the material transfer machine. The accommodating unit is located at the end of the trajectory. The three form a coordinated layout around the movement path of the material transfer machine. There is no need to reserve material transfer channels for each piece of equipment. This not only greatly reduces the overall floor space of the production line, but also reduces the complexity of equipment installation and maintenance. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to specific embodiments. Figures 1-3 The three-dimensional schematic diagrams of the post-processing assembly equipment for inductor coil components disclosed in this utility model are shown from three different perspectives. It can be seen that it is mainly composed of several parts, including a material feeding and transfer machine 1, a cutting machine 2, a holding unit 3, a laser displacement sensor 4, and a waste bin 5, to form a fully automated processing system for inductor coil components from post-welding acceptance, quality monitoring, wire cutting to finished product holding.

[0021] like Figures 1-3As shown, the material tray serves as the core material carrier, with its unloading station directly connected to the unloading and transfer machine 1. The unloading and transfer machine 1 receives the welded inductor coil assemblies and has the freedom to move along a preset trajectory. It precisely connects the material tray, cutting machine 2, waste bin 5, and holding unit 3. The cutting machine 2 is arranged along the movement trajectory of the unloading and transfer machine 1, and the position of its cutting end perfectly matches the position of the excessively long wires to be cut on the inductor coil assembly. When the unloading and transfer machine 1 moves the inductor coil assembly along the preset trajectory to the working area of ​​the cutting machine 2, the cutting machine 2 immediately starts and performs a precise cutting action, eliminating the need for manual adjustment of the assembly position and ensuring that the length error of each cut is controlled within a minimal range. The holding unit 3 is located at the end of the movement trajectory of the unloading and transfer machine 1 and is used to hold the inductor coil assembly after the wires have been cut, achieving orderly storage of the finished product. Laser displacement sensor 4 is positioned directly opposite the inductor coil assembly unloading station on the material tray. It uses laser detection technology to monitor the welding quality of the components in real time, such as weld point size and weld surface flatness, to screen out qualified semi-finished products and prevent defective products from entering the subsequent cutting process. Waste bin 5 is arranged along the movement trajectory of unloading and transfer machinery 1 and is located upstream of cutting machinery 2. Components deemed unqualified by laser displacement sensor 4 are directly transferred by unloading and transfer machinery 1 to waste bin 5 for collection and subsequent centralized processing.

[0022] In the above technical solution, by integrating the functions of material feeding and transfer, quality inspection, wire cutting, finished product storage, and waste collection into the same system, and with each component forming a coordinated layout around the preset trajectory of the material feeding and transfer machinery 1, there is no need to reserve a material transfer channel for a single device, thereby significantly reducing the overall floor space of the production line and reducing the complexity of equipment installation and maintenance.

[0023] It is also worth noting that the integrated transfer and continuous processing eliminates the waiting time difference between processes. This not only improves production efficiency but also ensures the consistency of finished product quality, effectively reducing the risk of component transfer damage and loss of defective products.

[0024] like Figure 4 , Figure 5 As shown, the material handling and transfer machine 1 mainly consists of several parts, including a lateral drive unit 11, a first picking robotic arm 12, and a second picking robotic arm 13. The lateral drive unit 11 preferably adopts a linear motor module, which has the advantages of smooth operation and high positioning accuracy. It provides a stable lateral movement driving force for the first picking robotic arm 12 and the second picking robotic arm 13, ensuring that the two remain synchronized during the lateral movement process, and the movement trajectory is fully adapted to the entire process path from picking up material from the material tray, to cutting by the cutting machine 2, and then to storing material in the holding unit 3.

[0025] As Figure 4 , Figure 5As shown, both the first picking robotic arm 12 and the second picking robotic arm 13 have independent lifting functions. Both are connected to the lateral drive unit 11 and perform lateral movement synchronously under the driving force of the lateral drive unit 11. The first picking robotic arm 12 is used to pick up the welded inductor coil assembly at the unloading station of the material tray through lifting action and laterally transport it to the working area of ​​the cutting machine 2. The first picking robotic arm 12 is specifically composed of a first linear drive actuator 121, a first support frame 122, and a first vacuum adsorption assembly 123. The first linear drive actuator 121 is loaded by the transverse drive unit 11, and its output end is fixedly connected to the first support frame 122. It provides stable and controllable power for the lifting and lowering action of the first picking robot arm 12, ensuring that the lifting height of the first vacuum adsorption component 123 is precisely matched with the stacking height of the components in the material tray when picking up materials from the material tray. The first vacuum adsorption component 123 is mounted on the first support frame 122 and the components are fixed by negative pressure adsorption. The adsorption force can be adjusted according to the actual situation of the inductor coil component.

[0026] The second picking robotic arm 13 is used to pick up the cut inductor coil assembly through a lifting motion after the cutting machine 2 has completed the cutting action, and transfer it to the receiving unit 3. The design structure of the second picking robotic arm 13 is similar to that of the first picking robotic arm 12, including a second linear drive actuator 131, a second support frame 132, and a second vacuum adsorption assembly 133. The second linear drive actuator 131 is also loaded by the lateral drive unit 11, and its output end is fixedly connected to the second support frame 132, driving the second picking robotic arm 13 to perform the lifting motion smoothly, ensuring that there is no shaking during the transfer of the finished product; the second vacuum adsorption assembly 133 uses the second support frame 132 as the mounting base and completes the cutting of the inductor coil assembly by negative pressure adsorption.

[0027] It should be noted that both the first linear drive actuator 121 and the second linear drive actuator 131 are preferably any one of a cylinder, a hydraulic cylinder, and a linear motor. The appropriate actuator can be flexibly selected based on the actual production requirements for lifting speed and load capacity. Its model and specifications can be adapted and adjusted according to the load differences between the first picking robotic arm 12 and the second picking robotic arm 13 to ensure the smoothness and accuracy of the lifting action.

[0028] As Figures 1-3As shown, the receiving unit 3 is composed of a first receiving fixture 31 and a second receiving fixture 32. The first receiving fixture 31 and the second receiving fixture 32 are arranged sequentially along the preset trajectory of the unloading and transfer machinery 1, and both are used to receive the inductor coil assembly after the wires have been cut. In this way, in practical applications, the first receiving fixture 31 and the second receiving fixture 32 are used to cooperate with the unloading and transfer machinery 1 to achieve the alternating reception of the inductor coil assembly. That is, when one of the receiving fixtures (the first receiving fixture 31 or the second receiving fixture 32) reaches its full capacity, the unloading and transfer machinery 1 directly transfers the subsequent finished assembly to the other receiving fixture without stopping the machine to wait for unloading, effectively avoiding production interruptions caused by unloading, and is especially suitable for continuous production needs under continuous material supply conditions.

[0029] Based on the above-mentioned inductor coil assembly post-processing combination equipment, the inductor coil assembly post-processing method specifically includes the following steps: S1. Material preparation and station flow: Place the inductor coil and lead wire board on the material tray in sequence. After the component is soldered and formed at the soldering station, the inductor coil component continues to flow to the inductor coil component unloading station. S2. Quality Inspection and Judgment: The laser displacement sensor 4 is activated to perform quality inspection on the inductor coil assembly at the material tray unloading station. By monitoring parameters such as the size of the solder joint and the flatness of the solder surface, it is determined whether the assembly is qualified. S3. Component Picking and Diversion Transfer: The first picking robotic arm 12 moves to the material tray unloading station and picks up components through lifting and vacuum suction. If the component is determined to be unqualified, the first picking robotic arm 12 transfers it to the waste bin 5 along a preset trajectory; if the component is determined to be qualified, the first picking robotic arm 12 transfers it to the cutting machine 2 operating area. S4. Precise wire cutting: When the material transfer machine 1 moves the qualified components to the cutting machine 2, the cutting machine 2 starts and its cutting end performs a precise cutting action on the excessively long wires on the components. S5. Finished product storage: After cutting, the second picking robot arm 13 picks up the cut components and moves them to the storage unit 3 along the preset trajectory. It is placed in the first storage fixture 31 first. After the first storage fixture 31 is full, it automatically switches to the second storage fixture 32 for placement. S6. Continuous Cyclic Operation: Repeat steps 1 to 5 above, relying on the continuous material preparation of the material tray and the alternating placement of the holding unit 3 to realize the continuous automated operation of the post-processing of the inductor coil assembly.

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.
