[0002] Inductors are among the most common components in circuits, playing a crucial role. As circuit integration increases, inductors are becoming smaller and smaller. Among them, surface-mount inductors are increasingly widely used due to their miniaturization, high quality, high energy storage, and low resistance.

[0003] The production of surface mount inductors involves multiple processes. Before packaging, each inductor undergoes electrical testing to determine if further packaging is necessary. During testing, multiple rows of inductors must be manually moved sequentially to the testing area for loading, a time-consuming and labor-intensive process that reduces production efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide an inductor feeding device and an inductor packaging equipment, which aims to solve the problem that when testing inductors, it is necessary to manually move multiple rows of inductors to the testing point in sequence for feeding, which is time-consuming and labor-intensive and reduces production efficiency.

[0005] To achieve the above objectives, the present invention proposes an inductor feeding device, comprising a base, a mold, a testing component, and a moving component. The base has an installation cavity; the mold is slidably disposed in the installation cavity and has a receiving groove for accommodating inductors; the testing component is used to perform electrical tests on the inductors; the moving component is movably connected to the base and is used to move the inductors to the testing component for testing.

[0006] In one embodiment, the base is provided with a guide portion located on the inner wall of the mounting cavity, and the mold is provided with a mating portion located at one end of the mold near the guide portion, wherein the guide portion and the mating portion are slidably engaged.

[0007] In one embodiment, one of the guide portion and the mating portion is a groove, and the other of the guide portion and the mating portion is a boss.

[0008] In one embodiment, the base is provided with a plurality of guide portions, all of which are located on the inner wall of the mounting cavity, and every two guide portions are arranged opposite to each other; the inductor feeding device includes a plurality of molds, each mold cooperating with two oppositely arranged guide portions.

[0009] In one embodiment, the mold has multiple receiving slots, which are spaced apart.

[0010] In one embodiment, the moving component is a negative pressure device, which is capable of attracting the inductor in the receiving tank to the test component.

[0011] In one embodiment, the inductive feeding device further includes a push-pull assembly, which is slidably connected to the base and is used to move the mold to the moving assembly.

[0012] In one embodiment, the push-pull assembly has a gripper located at one end of the push-pull assembly near the mold; the mold has a gripping groove located at one end of the mold near the gripper, and the gripper grips the mold through the gripping groove.

[0013] In one embodiment, the receiving groove has arc-shaped holes at both ends, and the inner peripheral wall of the arc-shaped holes is connected to two adjacent side walls of the receiving groove.

[0014] This utility model also proposes an inductor packaging device, including an inductor feeding device and a packaging device, wherein the packaging device is connected to the base and is used to package the inductors after testing.

[0015] The inductor feeding device of this utility model achieves efficient feeding and testing through the coordinated work of a base, mold, testing component, and moving component.

The moving component uses a cylinder or motor-driven slide rail structure, movably connected to the base, and can move the inductors horizontally and vertically within the mounting cavity, sequentially feeding them to the testing positions of the testing component. For example, after all the inductors on the mold have been placed, the moving component starts, moving the inductors in the receiving slots to below the testing component. The test probes press down to contact the inductors, completing the test, and preparing for the next round of feeding and testing. The mold's accommodating groove design enables precise positioning and stable placement of inductors, preventing damage or testing errors caused by improper operation during manual loading.

[0025] This utility model proposes an inductor feeding device 100.

[0026] Please see Figure 1 In one embodiment of this utility model, the inductor feeding device 100 includes a base 1, a mold 2, a testing component 3, and a moving component 4. The base 1 has an installation cavity 1a; the mold 2 is slidably disposed in the installation cavity 1a and has a receiving groove 2a for accommodating inductors; the testing component 3 is used to perform electrical tests on the inductors; the moving component 4 is movably connected to the base 1 and is used to move the inductors to the testing component 3 for testing.

[0027] The inductor feeding device 100 of this utility model achieves efficient feeding and testing through the coordinated operation of a base 1, a mold 2, a testing component 3, and a moving component 4. Specifically, the base 1 serves as the supporting structure for the entire device, and its internal mounting cavity 1a accommodates the mold 2. The base 1 is generally made of cast iron or alloy material, possessing stable and reliable characteristics. The mold 2 and the base 1 are slidably connected via guide rails or sliding grooves, and the mold 2 has one or more receiving grooves 2a on its surface. The size of each receiving groove 2a matches the shape of the inductor, enabling it to stably accommodate multiple inductors. In actual operation, the inductors are fed into the receiving grooves 2a of the mold 2 using a vibratory feeder or a robotic arm. The testing component 3 is mounted above the base 1 via bolts or clips, and includes an electrical test probe and a signal processing unit. The probe can accurately contact the pins of the inductor to measure electrical parameters. The moving component 4 employs a cylinder or motor-driven slide rail structure, movably connected to the base 1. It can move the inductors horizontally and vertically within the mounting cavity 1a, sequentially delivering them to the testing positions on the testing component 3. For example, after all the inductors on the mold 2 have been placed, the moving component 4 activates, moving the inductors in the receiving slot 2a to below the testing component 3. The test probe presses down to contact the inductor, completing the test, and then prepares for the next round of loading and testing. The design of the receiving slot 2a in the mold 2 enables precise positioning and stable placement of the inductors, avoiding damage or testing errors caused by improper operation during manual loading. The automated design of the moving component 4 significantly improves the efficiency of loading and testing, reduces manual intervention, and lowers labor intensity.

[0028] In one embodiment of this utility model, please refer to Figure 1 The base 1 is provided with a guide part 11, which is located on the inner wall of the mounting cavity 1a. The mold 2 is provided with a mating part 21, which is located at one end of the mold 2 near the guide part 11. The guide part 11 and the mating part 21 are slidably mated.

[0029] In this embodiment, the inner wall of the mounting cavity 1a of the base 1 is provided with a guide portion 11, and the mold 2 is provided with a mating portion 21 at one end near the guide portion 11. The guide portion 11 and the mating portion 21 slide together to achieve precise movement of the mold 2 within the mounting cavity 1a. Specifically, the guide portion 11 can be designed as a T-shaped guide rail, installed on the inner wall of the mounting cavity 1a of the base 1, and extending along the moving direction of the mold 2. The mating portion 21 is a T-shaped groove that matches the T-shaped guide rail and is provided on the side of the mold 2. When the mold 2 moves along the mounting cavity 1a under the drive of the moving component 4, the T-shaped groove and the T-shaped guide rail are tightly engaged to ensure that the mold 2 can only slide smoothly along the predetermined track without deviation or shaking. In practical applications, when the inductor on the mold 2 needs to be moved to the underside of the test component 3 for testing, the mold 2 is first smoothly slid out of the mounting cavity 1a along the T-shaped guide rail, and then the moving component 4 is activated. The moving component 4 accurately moves the inductor to the test position, and the test probe can accurately contact the inductor pin to complete the electrical test.

[0030] This invention achieves precise sliding and positioning of the mold 2 by setting a guide part 11 and a mating part 21 between the base 1 and the mold 2. The sliding fit design of the guide part 11 and the mating part 21 ensures the stability and smoothness of the mold 2 during movement, avoiding displacement of the mold 2 due to vibration or external force during movement, thereby improving the accuracy and reliability of inductor movement and testing. This structural design makes the installation and disassembly of the mold 2 more convenient, facilitating maintenance and replacement. For example, when it is necessary to replace the mold 2 to accommodate inductors of different sizes, simply slide the mold 2 out of the mounting cavity 1a along the guide part 11, replace it with a new mold 2, and then slide it back in; the operation is simple and quick. In addition, the tight fit between the guide part 11 and the mating part 21 can effectively reduce the friction between the mold 2 and the base 1, extend the service life of the equipment, and reduce maintenance costs.

[0031] In one embodiment of this utility model, please refer to Figure 1 and Figure 2 One of the guide portion 11 and the mating portion 21 is a groove, and the other of the guide portion 11 and the mating portion 21 is a boss.

[0032] In one embodiment, the guide portion 11 and the mating portion 21 are designed with a groove and a boss to achieve stable sliding of the mold 2 within the mounting cavity 1a of the base 1. Specifically, a groove can be machined into the inner wall of the mounting cavity 1a of the base 1 as the guide portion 11; and a boss matching the groove is provided at one end of the mold 2 near the base 1 as the mating portion 21. For example, the groove can be designed as a dovetail groove with inclined side walls, which can effectively prevent lateral displacement of the mold 2 during movement. The boss is correspondingly designed as a dovetail shape and fits tightly with the dovetail groove. When the mold 2 moves along the mounting cavity 1a under the drive of the moving component 4, the boss slides in the groove, ensuring that the mold 2 moves smoothly along the predetermined track. This groove and boss mating form is not only simple in structure but also easy to process, and can effectively improve the positioning accuracy and movement stability of the mold 2.

[0033] This structure significantly improves the positioning accuracy and stability of mold 2 during movement. Due to the tight fit between the groove and the boss, mold 2 will not experience lateral displacement or wobbling during movement, ensuring that the inductor accurately reaches the test position during testing, thus improving the accuracy and reliability of the test. The groove-boob fit provides high structural strength and wear resistance, enabling it to withstand large loads and frequent movement operations, extending the equipment's service life. For example, even under high-frequency movement operations during extended production, the fit between mold 2 and base 1 remains excellent, reducing equipment maintenance costs. Furthermore, this structural design facilitates the installation and disassembly of mold 2, improving equipment maintenance and replacement efficiency.

[0034] In one embodiment of this utility model, please refer to Figure 1 The base 1 is provided with multiple guide parts 11, all of which are located on the inner wall of the mounting cavity 1a, and each pair of guide parts 11 are arranged opposite to each other; the inductor feeding device 100 includes multiple molds 2, each mold 2 cooperating with two oppositely arranged guide parts 11.

[0035] In this embodiment, the inner wall of the mounting cavity 1a of the base 1 is provided with multiple guide portions 11, with each pair of guide portions 11 arranged opposite each other to form multiple sets of guide rails. The inductor feeding device 100 includes multiple molds 2, each mold 2 cooperating with two oppositely arranged guide portions 11 to achieve simultaneous sliding and positioning of multiple molds 2. Specifically, two or more sets of oppositely arranged guide portions 11 can be machined into the inner wall of the mounting cavity 1a of the base 1. For example, each set of guide portions 11 can be designed as a T-shaped guide rail or a dovetail groove. Each mold 2 has a mating portion 21 on both sides that matches the guide portion 11, such as a T-shaped slide groove or a dovetail boss. Taking a specific embodiment as an example, the inner wall of the mounting cavity 1a of the base 1 is provided with two sets of T-shaped guide rails, each set of guide rails consisting of two oppositely arranged T-shaped grooves. The inductor feeding device 100 includes two molds 2, each mold 2 having T-shaped slide grooves on both sides, which tightly cooperate with the T-shaped guide rails. When the equipment is started, the two molds 2 slide smoothly along their respective T-shaped guide rails in sequence, and the moving component 4 sends the inductors on the molds 2 to the test positions of the test component 3 in sequence.

[0036] This invention achieves simultaneous sliding and positioning of multiple molds 2 by setting multiple sets of guide parts 11 on the base 1 and cooperating with two oppositely arranged guide parts 11. This design significantly improves the production efficiency of the inductor feeding device 100. By operating multiple molds 2 simultaneously, more inductors can be processed at once, reducing waiting time and equipment idle time. The multi-mold design improves the flexibility and adaptability of the equipment. The number and layout of the molds 2 can be adjusted according to production needs; for example, the number of molds 2 can be increased when production volume is high and decreased when production volume is low, thereby optimizing the utilization rate of the equipment.

[0037] In one embodiment of this utility model, please refer to Figure 2 The mold 2 has multiple receiving slots 2a, which are spaced apart.

[0038] In one embodiment, the surface of the mold 2 has multiple spaced-apart receiving grooves 2a for accommodating inductors. Specifically, the mold 2 can be designed as a long strip or rectangular structure, with multiple receiving grooves 2a evenly distributed along its length. The size of each receiving groove 2a matches the shape of the inductor, enabling it to stably accommodate multiple inductors. This spaced-apart receiving groove design allows the mold 2 to accommodate multiple sets of inductors at once, improving loading efficiency.

[0039] In one embodiment of this utility model, please refer to Figure 1 The moving component 4 is a negative pressure device, which can attract the inductor in the receiving tank 2a to the test component 3.

[0040] In this embodiment, the moving component 4 uses a negative pressure device to achieve the adsorption and movement of the inductor. Specifically, the negative pressure device may include a vacuum pump and multiple suction cups, which are evenly distributed above the mold 2, corresponding to the positions of the receiving slots 2a. Each suction cup is connected to the vacuum pump via a pipe. When the vacuum pump is activated, the suction cups generate negative pressure, which can adsorb the inductor within the receiving slots 2a. For example, the mold 2 has 10 receiving slots 2a, and correspondingly 10 suction cups are provided. Each suction cup has a diameter of 5 mm, which can accurately adsorb small surface-mount inductors. A corresponding suction cup is also provided below the test component 3 to adsorb the inductor from the mold 2 and move it to the test position. After the inductor is adsorbed onto the test component 3, the vacuum pump stops working, and the inductor contacts the test probe under gravity, completing the test. After the test is completed, the vacuum pump restarts, and the suction cups adsorb the inductor onto the packaging device, ready for packaging. By employing a negative pressure device as the moving component 4, contactless adsorption and movement of the inductor can be achieved. The negative pressure adsorption method avoids damage to the inductor caused by mechanical clamping, and can effectively protect the inductor surface and leads, especially when handling small and precision inductors. Secondly, the adsorption and release process of the negative pressure device is rapid and stable, improving the efficiency and accuracy of inductor movement.

[0041] In one embodiment of this utility model, please refer to Figure 1 The inductive feeding device 100 also includes a push-pull assembly 5, which is slidably connected to the base 1 and is used to move the mold 2 to the moving assembly 4.

[0042] In one embodiment, the push-pull assembly 5 is slidably connected to the base 1, used to move the mold 2 to the position of the moving assembly 4. Specifically, the push-pull assembly 5 can be a cylinder or an electric push rod, with one end fixedly connected to the base 1 and the other end connected to the mold 2. For example, the inner wall of the mounting cavity 1a of the base 1 is provided with a slide rail, and both ends of the mold 2 are provided with sliders that match the slide rail. The movable end of the push-pull assembly 5 is connected to the slider of the mold 2. When the cylinder or electric push rod of the push-pull assembly 5 extends or retracts, the mold 2 moves smoothly along the slide rail. In actual operation, when the inductance on the mold 2 needs to be tested, the push-pull assembly 5 is activated, pushing the mold 2 from its initial position to the adsorption range of the moving assembly 4. The moving assembly 4 (such as a negative pressure device) then adsorbs the inductance and moves it to the testing assembly 3 for testing. The automated design of the push-pull assembly 5 reduces manual operation and improves production efficiency and consistency. The precise control of the push-pull assembly 5 ensures that the mold 2 accurately reaches the designated position each time, improving the stability and reliability of the equipment. The sliding connection design between the push-pull assembly 5 and the base 1 makes the movement of the mold 2 more stable, reducing the risk of inductor damage caused by vibration or impact during the movement.

[0043] In one embodiment of this utility model, please refer to Figure 1The push-pull assembly 5 has a gripper 51, which is located at one end of the push-pull assembly 5 near the mold 2; the mold 2 has a gripping groove 2b, which is located at one end of the mold 2 near the gripper 51, and the gripper 51 grips the mold 2 through the gripping groove 2b.

[0044] In this embodiment, the push-pull assembly 5 is equipped with a gripper 51, located at the end of the push-pull assembly 5 near the mold 2, for gripping the mold 2. The mold 2 has a gripping groove 2b at the end near the gripper 51, the shape and size of which match the gripper 51. Specifically, the gripper 51 can be designed as a pneumatic or electric gripper 51, with two opening and closing claw arms. The gripping groove 2b can be designed as a rectangular or circular groove, with its depth and width adjusted according to the size of the gripper 51. When the push-pull assembly 5 is activated, the gripper 51 opens, moves to the gripping groove 2b position of the mold 2, and then closes, tightly gripping the gripping groove 2b of the mold 2. Subsequently, the push-pull assembly 5 moves the mold 2 from its initial position to the adsorption range of the moving assembly 4 through the extension and retraction of a cylinder or electric push rod. This design ensures the stability and accuracy of the mold 2 during movement, while the cooperation between the gripper 51 and the gripping groove 2b facilitates quick replacement and maintenance of the mold 2.

[0045] In one embodiment of this utility model, please refer to Figure 2 The two ends of the receiving groove 2a are provided with arc-shaped holes 2c, and the inner peripheral wall of the arc-shaped holes 2c is connected to the two adjacent side walls of the receiving groove 2a.

[0046] In one embodiment, the receiving groove 2a can be designed as a rectangular groove, the length and width of which are adjusted according to the size of the inductor. At both ends of the receiving groove 2a, arc-shaped holes 2c are respectively provided, and the inner peripheral wall of the arc-shaped holes 2c is connected to the two adjacent side walls of the receiving groove 2a. This design can prevent the mold 2 from cracking or deforming during long-term use.

[0047] This utility model also proposes an inductor packaging device, which includes a packaging device and an inductor feeding device 100. The specific structure of the inductor feeding device 100 is as described in the above embodiments.
