Description

Technical Field

[0001] This utility model relates to the field of resistor technology, and in particular to an automatic resistor feeding and winding device. Background Technology

[0002] The opposition a conductor makes to the flow of electric current is called its resistance. Resistance (usually represented by "R") is a physical quantity that, in physics, indicates the magnitude of a conductor's opposition to the flow of electric current. The greater the resistance of a conductor, the greater its opposition to the flow of current. Different conductors generally have different resistances; resistance is an intrinsic property of the conductor. The resistance of a conductor is usually represented by the letter R, and the unit of resistance is the ohm, abbreviated as Ω. During the manufacturing process of a resistor, a resistance wire needs to be wound around it.

[0003] The existing technology, CN2022100668313, describes a resistor winding machine with a feeding function. The existing technology uses pushing or sliding feeding for both feeding and unloading. This feeding method may cause wear to the wound resistors. In addition, manual packaging is required after unloading, so further processing is needed. Furthermore, the winding gap of the existing winding mechanism cannot be guaranteed, so the winding effect cannot be guaranteed.

[0004] Therefore, it is necessary to design an automatic resistor feeding and winding device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic resistor feeding and winding device to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic resistor feeding and winding device includes a frame, characterized in that it further includes a feeding module mounted on the frame, a picking module corresponding to the feeding module, a clamping module located beside the picking module, and a winding module located beside the clamping module and cooperating with the resistor winding. The feeding module includes a feeding rack extending through the frame, a slide rail mounted on the feeding rack, a multi-layer feeding rack slidably mounted on the slide rail via a slider, and a servo motor with a lead screw structure connected to the multi-layer feeding rack. The picking module includes a picking rack located beside the multi-layer feeding rack. The material handling module includes a movable slide rail mounted on the material handling rack, a material handling plate slidably mounted on the movable slide rail via a slider, and a power unit that drives the material handling plate to move along the movable slide rail. The clamping module includes a robotic arm, a clamping plate driven by the robotic arm, a rotary motor mounted on the clamping plate, a gripper mounting base driven by the rotary motor, a first clamping assembly and a second clamping assembly mounted on the gripper mounting base. The first clamping assembly and the second clamping assembly have the same structure and are set at a 90-degree angle. The first clamping assembly includes a telescopic cylinder, a clamping cylinder driven by the telescopic cylinder, and a gripper driven by the clamping cylinder.

[0008] Preferably, the multi-layer feeding rack is divided into several layers.

[0009] Preferably, a limiting mechanism is provided on both the left and right sides of the material receiving plate, and the limiting mechanisms on the left and right sides are symmetrically arranged. The limiting mechanism includes a mounting base, a limiting cylinder disposed on the mounting base, and a limiting plate driven by the limiting cylinder.

[0010] Preferably, the winding module includes a mounting frame, clamping modules disposed on both sides of the mounting frame and symmetrically arranged, a tensioning mechanism disposed on the rear side of the clamping modules for mounting the resistance wire, a welding module disposed between the clamping modules, and a pushing module used in conjunction with the tensioning mechanism for conveying the resistance wire.

[0011] Preferably, the clamping module includes a drive cylinder, a clamping block driven by the drive cylinder, and a servo motor that drives the clamping block to rotate.

[0012] Preferably, the welding modules are symmetrically arranged vertically in the middle of the clamping space of the clamping module, and each module includes a drive cylinder and a welding head.

[0013] Preferably, the pushing module includes a guide rod disposed on the mounting bracket, a guide seat fitted on the guide rod, a drive unit connected to the guide seat via a lead screw assembly, a guide head mounted on the guide seat and used to cooperate with the resistor wire installation, and a pushing cylinder that drives the guide head to approach or move away from the resistor.

[0014] The beneficial effects of this utility model are as follows: This technical solution, by setting up a feeding module and a picking module, achieves automatic feeding and unloading through the coordinated use of the feeding module and the picking module. At the same time, the clamping module accurately picks up resistors. The first clamping component and the second clamping component work alternately. One group drives out the wound resistors, and the other group places the resistors to be wound into the winding module for winding. Then, it moves to the picking module, places the wound resistors into the material box, and at the same time, the other group clamps the resistors to be wound again. This cycle is repeated to speed up the winding efficiency and ensure uninterrupted operation. At the same time, by setting up a pushing module to cooperate with the automatic movement and winding of the resistors, the winding of the resistor wire with equal gaps is achieved.

[0020] Reference Figures 1 to 4 An automatic resistor feeding and winding device includes a machine frame 1, a feeding module 2 disposed on the machine frame, a picking module 3 disposed corresponding to the feeding module, a clamping module 4 disposed on the side of the picking module, and a winding module 5 disposed on the side of the clamping module.

[0021] The feeding module includes a feeding rack 21 that runs through the equipment frame, a slide rail 22 that is mounted on the feeding rack, a multi-layer feeding rack 23 that is slidably mounted on the slide rail via a slider, and a lead screw structure 24 connected to the multi-layer feeding rack by a servo motor 25. The method of driving the multi-layer feeding rack to move up and down along the feeding rack is not limited to the method of using a lead screw structure and a servo motor, but can also be driven by electricity, cylinder, hydraulics, etc., to achieve up and down movement. The multi-layer feeding rack is divided into several layers, and each layer holds a material box for holding resistor products. Each layer is filled with material boxes to cooperate with the material picking module.

[0022] The material picking module 3 includes a material picking rack 31 disposed on the side of the multi-layer feeding rack, a movable slide rail 32 disposed on the material picking rack, a material picking plate 33 slidably mounted on the movable slide rail via a slider, and a power unit for driving the material picking plate to move along the movable slide rail.

[0023] The material picking plate can move along the sliding rail and be placed in the multi-layer feeding rack. The width of the material picking plate is smaller than the width of the multi-layer feeding rack, and limit plates are provided on the front and rear sides of the material picking plate. After the material picking plate moves into the multi-layer feeding rack, the material box containing the resistor falls onto the material picking plate, and the limit plates on both sides limit the front and rear positions of the plate.

[0024] To improve the accuracy of the robotic arm in picking up resistors from the material box, limit mechanisms 34 are provided on both the left and right sides of the picking plate. The left and right limit mechanisms are symmetrically arranged. Each limit mechanism includes a mounting base, a limit cylinder mounted on the mounting base, and a limit plate driven by the limit cylinder. By simultaneously driving the left and right limit mechanisms, the limit cylinder drives the limit plate, and the left and right limit plates move closer to each other, thereby limiting the picking plate. At the same time, the limit plates on the front and rear sides also limit it, and the four sides are restricted synchronously, thereby adjusting the position of the material box. After the position of the material box is ensured, the robotic arm can accurately pick up the resistors from the material box.

[0025] The gripping module 4 includes a robotic arm 41, a gripping plate 42 driven by the robotic arm, a rotary motor 43 mounted on the gripping plate, a gripper mounting base 44 driven by the rotary motor, a first gripping assembly 45 and a second gripping assembly 46 mounted on the gripper mounting base. The first gripping assembly and the second gripping assembly have the same structure and are set at a 90-degree angle. The first gripping assembly includes a telescopic cylinder 451, a gripping cylinder 452 driven by the telescopic cylinder, and a gripper 453 driven by the gripping cylinder. Specifically, the entire gripping assembly is driven by the robotic arm. Partially moving closer to the material plate and winding module, the rotation motor drives the first clamping component and the second clamping component to rotate, adjusting their positions, thereby driving the first clamping component or the second clamping component to approach the resistor rod for clamping. The first clamping component and the second clamping component work alternately. One group drives out the wound resistor and flips it to the other group. The other group then places the resistor to be wound into the winding module for winding, and then moves it to the material picking module 3 to place the wound resistor into the material box. At the same time, the other group clamps the resistor to be wound again. This cycle is repeated to speed up the winding efficiency.

[0026] The winding module 5 includes a mounting frame 51, clamping modules 52 arranged symmetrically on both sides of the mounting frame, a tensioning mechanism 53 arranged on the rear side of the clamping modules for mounting the resistance wire, a welding module 54 arranged between the clamping modules, and a pushing module 55 used in conjunction with the tensioning mechanism for conveying the resistance wire.

[0027] The clamping module includes a drive cylinder 511, a clamping block 512 driven by the drive cylinder, and a servo motor 513 that drives the clamping block to rotate. The clamping modules on both sides synchronously drive the cylinders to move relative to each other, so that the clamping blocks on both sides press against the two ends of the resistor to clamp it. Then, the servo motor drives the resistor to rotate, which in turn cooperates with the winding.

[0028] The tensioning mechanism is based on the same principle as the wire drawing tensioning mechanism in the prior art. It is used to wind the resistance wire and deliver the resistance wire to the pushing module, and is installed in conjunction with the pushing module.

[0029] The welding modules are symmetrically arranged in the middle of the clamping space of the clamping module, and include a drive cylinder and a welding head. At the beginning, the drive cylinder drives the welding head to approach the resistor, thereby welding the end of the resistor wire to the resistor and resetting it. By using other equipment, the wire is wrapped around the outside of the resistor. Finally, the welding head welds the resistor wire to the other end and disconnects it from the resistor.

[0030] The pushing module 55 includes a guide rod 551 mounted on the mounting bracket, a guide seat 552 fitted on the guide rod, a drive unit 553 connected to the guide seat via a lead screw assembly, a guide head 554 mounted on the guide seat for mounting a resistance wire, and a pushing cylinder 555 that drives the guide head to approach or move away from the resistor. The pushing cylinder drives the guide head with the resistance wire to approach the clamped resistor, placing the resistance wire at one end of the resistor. The wire is then welded and fixed to one end of the resistance wire by a welding module. Simultaneously, the clamped resistor is driven to rotate, and the drive unit drives the guide seat to move along the guide rod, i.e., horizontally along the resistor, winding the resistance wire around the resistor until it reaches the other end and stops synchronously. Then, the welding module disconnects the resistance wire from the resistor, while fixing the resistance wire at the other end. The pushing cylinder then resets, completing the winding of the resistor.

[0031] In this implementation, each layer of the multi-layer feeding rack contains a material box, and several resistors are sequentially placed inside each material box. A servo motor drives the multi-layer feeding rack to move up and down, thus moving the corresponding layer to a position where the picking module can pick up the material. The picking module, driven by a power source, moves the picking rack along a sliding rail and positions it within the multi-layer feeding rack, specifically at the bottom of the material box to be picked up. Then, by moving the multi-layer feeding rack downwards, the corresponding material box is placed on the picking rack, positioned between the limiting plates on the front and rear sides of the picking plate. The picking plate then picks up the material box. Afterwards, the device is reset away from the multi-layer feeding rack (similarly, the empty material box can be placed back on the multi-layer feeding rack). Simultaneously driven by the limiting mechanisms on both sides, the limiting cylinder drives the limiting plate, causing the left and right limiting plates to move closer together, thus limiting the material picking plate. At the same time, the front and rear limiting plates also limit it, restricting the entire perimeter, thereby adjusting the position of the material box. After the material box is positioned correctly, it awaits the robotic arm to grasp it. The robotic arm moves, and the first and second gripping components work alternately, one set removing the wound resistor. The circuit is flipped to another group, where the resistor to be wound is placed in the winding module and wound. Then it moves to the material handling module 3, where the wound resistor is placed in the material box. Simultaneously, another group picks up the resistor to be wound, and this process is repeated. The resistor is placed between the clamping modules on both sides, and the clamping modules synchronously drive the cylinders to move relative to each other, so that the clamping blocks on both sides press against both ends of the resistor for clamping. The pushing cylinder drives the belt towards the guide head with the resistance wire, bringing the resistance wire to one end of the resistor. Then, the welding module welds the wire to fix it in place. After one end of the resistance wire is welded, it is driven to rotate, causing the resistor to rotate. At the same time, the drive unit drives the guide seat to move along the guide rod, that is, to move horizontally along the resistor, winding the resistance wire around the resistor until it reaches the other end and stops synchronously. Then, the welding module disconnects the resistance wire from the resistor, while fixing the other end of the resistance wire. The cylinder is pushed to reset, completing the winding of the resistor. After the winding is completed, it is taken out, another set of resistors is placed in the clamp, and the clamped resistors are put back into the material box. Another set of clamping components picks up the resistors to be wound, and the work is repeated.

[0032] The advantages of this utility model are that, by setting up a feeding module and a picking module, the automatic feeding and unloading are achieved through the coordinated use of the feeding module and the picking module. At the same time, the clamping module accurately picks up resistors. The first clamping component and the second clamping component work alternately. One group drives out the wound resistors, and the other group places the resistors to be wound into the winding module for winding. Then, the module moves the winding resistors to the picking module and places them into the material box. At the same time, the other group clamps the resistors to be wound again. This cycle is repeated to speed up the winding efficiency and ensure uninterrupted operation. In addition, by setting up a pushing module to cooperate with the automatic movement and winding of the resistors, the winding of the resistor wire with equal gaps is achieved.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
