Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an automatic loading and unloading structure for a surface mount inductor winding machine. Background Technology

[0002] Surface mount inductors, as crucial electronic components, are widely used in computers, mobile communications, consumer electronics, and automotive electronics. With the miniaturization, thinning, and high performance of electronic products, the size requirements for surface mount inductors are decreasing, while the demands on their production efficiency and winding quality are increasing. In the manufacturing process of surface mount inductors, the winding process is the core step, and the loading and unloading efficiency of the winding machine directly determines the overall production line capacity. Traditional surface mount inductor production often uses semi-automatic or manually assisted methods for loading and unloading, which is not only labor-intensive and costly, but also prone to damage or misalignment of the inductor coil due to human error, severely affecting product consistency and yield. Therefore, developing an automated loading and unloading structure that enables precise positioning and rapid flow is of great significance for improving the overall performance of surface mount inductor winding machines.

[0003] The automatic loading and unloading mechanisms of existing surface mount inductor winding machines mostly consist of a frame, a feeding assembly, a picking assembly, a receiving assembly, and a winding machine located on one side of the frame. The feeding assembly uses a vibratory feeder and a linear vibrating track to transport materials. The picking assembly uses a cylinder to drive a robotic arm to move back and forth between the feeding end and the winding station. It uses a suction nozzle or gripper to transfer the surface mount inductor to be processed onto the winding fixture. After winding, the finished product is transferred to the receiving assembly, thus replacing manual operation to a certain extent and realizing the automation of production.

[0004] However, the aforementioned existing technologies still have some shortcomings in practical applications. First, the transfer structure of such mechanisms is relatively rigid. When the robotic arm performs long-distance reciprocating transport, the inertial impact of the cylinder drive is relatively large, which can easily cause vibration during high-speed start-stop processes. This can lead to displacement or even drop when adsorbing or clamping micro-patch inductors, affecting the accuracy of loading. Second, the connection between the loading / unloading module and the winding spindle is not tight enough. In multi-station continuous winding operations, relying solely on uniaxial linear movement is often insufficient to meet the high-frequency production demands, making the loading / unloading process a bottleneck that limits overall production efficiency. In addition, existing unloading and storage structures often lack effective buffering and sorting mechanisms. Finished inductors are prone to collisions or stacking disorder during unloading due to direct drop into the material box, increasing the difficulty of subsequent packaging processes. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention aims to provide an automatic loading and unloading structure for a surface mount inductor winding machine. This structure solves the technical problems in the existing surface mount inductor winding production process, where the loading and unloading processes rely on manual labor or semi-automatic equipment, resulting in low production efficiency, high labor intensity, poor positioning accuracy, and difficulty in adapting to high-cycle automated production.

The motor base is erected on the top of the base, and the rotary disk is coaxially connected to the end of the motor base. Multiple sets of fixed bases are arranged in a circular array and installed on the surface of the rotary disk. The connecting shaft base is installed on the fixed base. The inner shaft is connected to the end face of the connecting shaft base away from the rotary disk. A trapezoidal sleeve is movably fitted on the outer wall of the inner shaft. The spring is connected between the end face of the inner shaft near the connecting shaft base and the connecting shaft base and is fitted on the inner shaft. The suction head A can be opposite to the end of one set of inner shafts closest to it.

[0014] As a preferred embodiment of the present invention, the feeding mechanism includes a feeding base, a slide rail, a mounting rod, a servo motor B, a suction head B, and a hose. The feeding base is located horizontally on the side of the rotary module.

An inclined receiving tray is installed on the side of the feeding frame, and the suction head B can be moved to directly above the receiving tray.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention integrates a feeding mechanism, feeding module A, a rotary module, an unloading mechanism, and feeding module B to construct a fully automated closed-loop system for surface mount inductor winding production. This system can continuously complete automatic feeding, precision shifting, multi-station winding, and finished product unloading and conveying of surface mount inductors, effectively replacing traditional manual or semi-automatic loading and unloading operations. This not only significantly reduces the labor intensity of workers and the company's labor costs, but also eliminates quality risks such as inductor coil damage and positional misalignment caused by unstable manual operation, significantly improving product consistency and the overall yield rate of the production line, meeting the dual requirements of high efficiency and high quality in surface mount inductor production.

[0019] 2. This invention features optimized design in the transfer and positioning stages, significantly improving the accuracy and efficiency of loading and unloading. The feeding module A employs a drive system combining a cylinder and a servo motor A. Utilizing the precise control capability of the servo motor A, the suction head can be flexibly adjusted in angle, achieving high-precision alignment with the clamps on the rotary module. This avoids the inertial vibration and positioning errors caused by traditional rigid cylinder direct push. Simultaneously, the rotary module adopts a multi-station design with a ring-array distribution, combined with an adaptive clamping structure composed of trapezoidal sleeves and springs. This allows winding and loading / unloading operations to be processed in parallel, effectively solving the production cycle bottleneck problem caused by the single-axial movement structure in existing technologies and significantly increasing the production capacity per unit time.

[0020] 3. This invention also features a significantly improved unloading and collection structure for finished products, effectively solving the problems of easy damage and disordered stacking. The unloading mechanism uses a servo motor B to drive the suction head B for flexible material handling, and coordinates with the sliding rails to smoothly transport the material above the feeding module B, avoiding hard collisions caused by direct dropping. The feeding module B is equipped with a conveyor belt and a wedge-shaped baffle bar. This baffle bar effectively limits and guides the surface-mount inductors during the conveying process, preventing the tiny inductors from jumping off or scattering due to conveyor belt vibration. Combined with the receiving tray at the end, this achieves orderly buffered collection of finished products, greatly reducing the difficulty of subsequent material handling and packaging, and protecting the integrity of the wound finished products.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Please see Figures 1 to 7 The present invention provides an automatic loading and unloading structure for a chip inductor winding machine, which mainly includes a loading mechanism 2 and a feeding module A3 mounted on a base 1, and a rotary module 5, an unloading mechanism 6 and a feeding module B7 mounted on a base 4.

[0032] 1. Structural layout of the feeding mechanism and feeding module A

[0033] like Figure 1 and Figure 2 As shown, the feeding mechanism 2 is mainly responsible for feeding the surface mount inductors. A support column 21 is fixed on the base 1, and a mounting base 22 is installed at the top of the support column 21. A feeding tray 23 is installed at an inclination inside the mounting base 22. A hopper 24 is provided above the feeding tray 23. The feeding port of the hopper 24 extends into the mounting base 22 and is aligned with the feeding tray 23 to store a large number of surface mount inductors to be processed. A vibrating feeding tray 25 is also mounted on the top of the base 1. The outlet end of the feeding tray 23 extends above the vibrating feeding tray 25 to guide the material into the tray. The outlet end of the vibrating feeding tray 25 is connected to a horizontally set feeding guide rail 26. Through vibration screening, the surface mount inductors are arranged in an orderly manner and transported to the picking position.

[0034] The feeding module A3 is located on the side of the feeding guide rail 26 and is used to transfer the arranged chip inductors to the winding station. The specific structure is as follows: a mounting frame 31 is erected on the base 1 on the side of the feeding guide rail 26, and a support plate 32 parallel to the guide rail is fixed on the top of the mounting frame 31; an L-shaped seat 33 is installed on the end of the support plate 32 away from the mounting frame 31; a slide table 34 is slidably installed on the L-shaped seat 33, and a cylinder A35 is installed on the side wall of the L-shaped seat 33. The output end of the cylinder A35 is connected to the slide table 34, driving the slide table 34 to perform horizontal reciprocating motion in a direction perpendicular to the axis of the feeding guide rail 26.

[0035] To achieve the lifting and rotation adjustment of the feeding head, a C-shaped mounting bracket 36 is fixedly installed on the slide table 34; a vertical guide rail is provided on the inner side of the mounting bracket 36, through which a C-shaped movable seat 37 is slidably installed; a cylinder B38 is installed on the top of the mounting bracket 36, and its output rod passes through the top of the bracket and connects to the movable seat 37, driving the movable seat 37 to lift and lower; a connecting seat 39 is connected to the inner side of the movable seat 37, and a hinge seat 310 is provided on the end face of the connecting seat 39; a suction head A311 is hinged to the inner side of the hinge seat 310, and a servo motor A312 is installed on the side wall of the hinge seat 310. The output shaft of the servo motor A312 is connected to the hinge shaft of the suction head A311 through a coupling, thereby driving the suction head A311 to perform angle flipping or fine adjustment to adapt to the installation angle of the winding fixture.

[0036] 2. Structural layout of the rotary module

[0037] like Figure 1 and Figure 3As shown, the rotary module 5 is the core load-bearing component for winding operations; a motor seat 51 is erected on the top of the base 4, and a drive motor is installed inside the motor seat 51, with its output end coaxially connected to the rotary disk 52; multiple sets of fixed seats 53 are distributed in a circular array along the circumferential direction on the surface of the rotary disk 52; a connecting shaft seat 54 is installed on each fixed seat 53, and an outwardly extending inner shaft 56 is fixed on the connecting shaft seat 54; a trapezoidal cross-section clamp 55 is movably fitted on the outer wall of the inner shaft 56, and a spring 57 is provided on the inner shaft 56, located between the clamp 55 and the connecting shaft seat 54.

[0038] The structure utilizes the elastic force of spring 57 to push the clamp 55, and in conjunction with the structure at the end of the inner shaft 56 (usually an expansion and contraction structure or a fixture), to achieve automatic clamping and fixing of the chip inductor; the suction head A311, driven by the feeding module A3, can move to a position opposite to one of the inner shafts 56 ends for feeding.

[0039] 3. Structural layout of the unloading mechanism and feeding module B

[0040] like Figure 1 , Figure 4 and Figure 5 As shown, the unloading mechanism 6 is located on the side of the rotary module 5 and is used to remove the wound product. The rotary module 5 has a horizontal unloading base 61 on its side, and two sets of slide rails 62 are laid parallel on the surface of the unloading base 61. An mounting rod 63 is slidably mounted on the slide rails 62. The bottom of the unloading base 61 has a through groove 68, and a cylinder C67 is installed below the base. The bottom of the mounting rod 63 has a connector 69, which passes through the groove 68 and connects to the cylinder C67, so that the cylinder C67 drives the mounting rod 63 to move horizontally along the slide rails 62. A servo motor B64 is installed inside the mounting rod 63, and its output shaft is connected to the suction head B65 through a coupling. The suction head B65 is connected to a vacuum generator (not shown) through a hose 66 to achieve negative pressure suction.

[0041] like Figure 6 As shown, the feeding module B7 is located on the output side of the unloading mechanism 6, and its axis is perpendicular to the unloading base 61. It includes a feeding frame 71 and a conveyor belt 72 installed inside it. A servo motor C74 is installed on the side of the feeding frame 71 to drive the conveyor belt 72 to rotate. To prevent the tiny chip inductors from deviating during conveying, wedge-shaped baffles 73 are installed on the top of the feeding frame 71 on both sides of the conveyor belt 72. An inclined receiving tray 75 is installed on the end side of the feeding frame 71 for collecting finished products.

[0042] 4. Working principle

[0043] The working process of this invention is as follows:

[0044] (1) Feeding stage: Pour the chip inductor to be wound into the hopper 24, and the material slides into the vibrating feeder 25 through the feeding tray 23. The vibrating feeder 25 organizes the messy inductor through vibration and then transports it to the feeding end in an orderly manner along the feeding guide 26.

[0045] (2) Feeding stage: When the feeding module A3 is working, the cylinder A35 drives the slide 34 to move, so that the suction head A311 is aligned with the inductor at the end of the feeding guide rail 26; the cylinder B38 drives the movable seat 37 to descend, and the suction head A311 picks up the inductor and rises; then, the slide 34 moves to one side of the rotary module 5, and the servo motor A312 drives the suction head A311 to rotate and adjust the inductor angle as needed, so that it is consistent with the direction of the clamp on the rotary module 5.

[0046] (3) Clamping and winding stage: The suction head A311 feeds the inductor into the end of the inner shaft 56 of the rotary module 5. Under mechanical thrust or external assistance, it overcomes the resistance of the spring 57 and uses the clamp 55 to firmly clamp the inductor. Then the suction head A311 releases and retracts. The rotary table 52 drives the clamped inductor to rotate to the winding station (the winding head is not shown in the figure, but is a conventional supporting equipment). The rotary module 5 drives the inductor to rotate to cooperate with the winding.

[0047] (4) Unloading and conveying stage: After the winding is completed, the rotary table 52 transfers the finished product to the unloading station; the cylinder C67 of the unloading mechanism 6 drives the mounting rod 63 to approach the rotary module 5, and the servo motor B64 adjusts the angle of the suction head B65 to align with the finished product inductor and sucks it down; then the cylinder C67 retracts, and the suction head B65 moves to the top of the conveyor belt 72 of the feeding module B7 to release the material; the conveyor belt 72 is driven by the servo motor C74 to convey the finished product, and after being guided by the baffle bar 73, it falls into the receiving tray 75 to complete the collection.

[0048] In summary, this invention achieves automated loading and unloading of the entire surface mount inductor winding process through the coordinated action of each module, resulting in a compact structure and efficient operation.
