Description
Technical Field
[0001] This utility model relates to the field of washing machine foot manufacturing technology, and in particular to a feeding device for assembling washing machine feet. Background Technology
[0002] In the manufacturing process of washing machines, the assembly of the washing machine's base nuts is one of the key steps. The accurate installation of the base nuts not only affects the stability of the washing machine but also has a significant impact on the shock absorption effect during the operation of the washing machine. Traditional washing machine foot nut loading methods typically use a simple vibratory feeder combined with a robotic arm for clamping and placement. However, due to the lack of a pre-positioning structure, the robotic arm's clamping part may not be able to grip the flat surface of the nut, which greatly reduces the clamping stability and makes it easy for the nut to be placed at an angle, affecting subsequent assembly. In addition, after placement, the screw base with the nut may become tilted due to slight vibration during transportation, which may also affect subsequent assembly. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a feeding device for assembling washing machine feet. This feeding device is used for feeding washing machine foot nuts. During the feeding process, a pre-positioning structure is used to ensure that one side of the foot nut faces forward, facilitating subsequent clamping by the mechanical gripper. In addition, during the feeding process, fewer rotations can be achieved, allowing the nut to be pre-assembled on the screw, preventing loosening during transport after assembly and affecting subsequent tightening.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for assembling the feet of a washing machine includes a guide seat, an extension plate fixedly connected to the right side of the guide seat, a rectangular groove at the upper end of the guide seat, and a plate-shaped electromagnet for pre-positioning on the front side wall of the rectangular groove; a pushing assembly, which includes a first cylinder installed on the left side of the guide seat, the telescopic end of the first cylinder extending into the rectangular groove and fixedly connected to an abutment bar; and a rotating feeding assembly installed on the upper end of the extension plate.
[0005] Preferably, the right side of the abutment bar has a V-shaped surface, and the included angle of the V-shaped surface is 120°.
[0006] Preferably, the rotary feeding assembly includes a connecting frame mounted on the upper end of the extension plate. The connecting frame is composed of a vertical plate and a horizontal plate. An electric slide rail is mounted on the lower end of the horizontal plate, and a U-shaped frame is fixedly connected to the sliding part of the electric slide rail.
[0007] Preferably, a second cylinder is installed at the inner bottom of the spiral frame, the telescopic end of the second cylinder passes through the spiral frame and is fixedly connected to a mounting housing, a drive motor is installed inside the mounting housing, the output shaft of the drive motor passes through the mounting housing and is fixedly connected to a mechanical clamping hand.
[0008] Preferably, the side wall of the mounting housing has a plurality of heat dissipation vents.
[0009] Preferably, the rear side of the guide seat is provided with a connecting channel that mates with the rectangular groove.
[0010] Compared with the prior art, the advantages of this utility model are as follows: 1. The plate-shaped electromagnet can cause the base nut of the non-maximum contact surface to rotate to the appropriate position on the front side wall of the rectangular groove, complete the automatic calibration, ensure that the subsequent mechanical clamping hand can accurately clamp, improve the clamping success rate and assembly accuracy, and reduce assembly errors caused by unstable clamping.
[0011] 2. The second cylinder drives the mechanical clamping hand to descend and clamp the nut. The electric slide rail moves to the position to be placed. Then, the second cylinder extends and the drive motor drives the rotation, so that the nut is pre-assembled on the screw. This can effectively prevent loosening during transportation after assembly, ensure the quality of subsequent tightening and assembly, and improve the overall assembly stability.

[0013] In the diagram: 1 guide seat, 2 rectangular groove, 3 L-shaped baffle plate, 4 connecting channel, 5 first cylinder, 6 extension plate, 7 connecting frame, 8 electric slide rail, 9 U-shaped frame, 10 second cylinder, 11 mounting housing, 12 mechanical clamping hand, 13 abutment bar, 14 V-shaped surface, 15 plate electromagnet. Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Reference Figures 1-3A feeding device for assembling the feet of a washing machine includes a guide seat 1. The guide seat 1 is installed in one of the processes of the foot assembly area. An extension plate 6 is fixedly connected to the right side of the guide seat 1. A rectangular groove 2 is opened at the upper end of the guide seat 1. A connecting channel 4 that docks with the rectangular groove 2 is provided on the rear side of the guide seat 1. The rear side of the connecting channel 4 docks with an existing vibrating plate containing foot nuts to realize pre-feeding operation. The further base nut consists of a nut part at the bottom and a ring part at the top. The height of the nut part is higher than the upper end face of the guide seat 1. A plate-shaped electromagnet 15 for pre-positioning is provided on the front side wall of the rectangular groove 2. When feeding, the plate-shaped electromagnet 15 is activated first. At this time, if the base nut of the rectangular groove 2 is not in a plane and contacts the front side wall of the rectangular groove 2, it will rotate due to magnetic force, so that the surface with the largest contact with the front side wall of the rectangular groove 2 (i.e., one side) contacts the front side wall of the rectangular groove 2, completing automatic calibration, so that one side is facing forward, which is convenient for the subsequent mechanical clamping hand 12 to perform clamping operation.
[0016] The system also includes a material pushing assembly, which includes a first cylinder 5 installed on the left side of the guide seat 1. The first cylinder 5 is of model SC100. The telescopic end of the first cylinder 5 extends into the rectangular groove 2 and is fixedly connected to an abutment bar 13. The abutment bar 13 has a pushing function and an intercepting function for subsequent vibratory feeder feeding, ensuring that only one material is fed at a time. A V-shaped surface 14 is provided on the right side of the abutment bar 13. The included angle of the V-shaped surface 14 is 120°, which fits perfectly with the two sides of the nut, ensuring the stability of subsequent pushing.
[0017] The system also includes a rotary feeding assembly, which is installed on the upper end of the extension plate 6. The rotary feeding assembly includes a connecting frame 7 installed on the upper end of the extension plate 6. The connecting frame 7 consists of a vertical plate and a horizontal plate. An electric slide rail 8 is installed at the lower end of the horizontal plate. The electric slide rail 8 is existing technology; after activation, it allows movement of the sliding part. A U-shaped frame 9 is fixedly connected to the sliding part of the electric slide rail 8. A second cylinder 10, model SC125, is installed at the inner bottom of the U-shaped frame 9. The telescopic end of the second cylinder 10 passes through the U-shaped frame 9 and is fixedly connected to a mounting... The housing 11 has several heat dissipation vents on its side wall. A drive motor, model 17HS4023, is installed inside the housing 11. The output shaft of the drive motor passes through the housing 11 and is fixedly connected to a mechanical gripper 12. The mechanical gripper 12 is electrically driven and has a built-in battery. With the help of a wireless control module, it can be wirelessly controlled to avoid interference from the wires during rotation. In addition, the opposite surfaces of its gripping part are flat, which fits the front and rear side planes of the nut to ensure stable gripping.
[0018] In this utility model, the vibratory feeder is started, and the bottom nut is conveyed into the rectangular groove 2 through the connecting channel 4 to realize the pre-loading operation; The plate electromagnet 15 is activated. If the base nut does not contact the front wall of the rectangular groove 2 with the maximum contact surface (i.e., one side), the base nut will rotate under the action of magnetism until one side faces the front and contacts the front wall of the rectangular groove 2 with the maximum area, completing the automatic calibration and preparing for the subsequent clamping operation of the mechanical gripper 12. The first cylinder 5 is activated, and the telescopic end drives the abutment bar 13 to move, pushing the automatically calibrated base nut in the rectangular groove 2 to the right to the extension plate 6. After the abutment bar 13 pushes the base nut to the appropriate position, the second cylinder 10 is activated, driving the mounting housing 11 and the mechanical clamping hand 12 to move downwards to the appropriate position. The mechanical clamping hand 12 is activated and clamps the automatically calibrated base nut. Subsequently, the electric slide rail 8 drives the U-shaped frame 9 to move, so that the mechanical clamping hand 12 reaches the placement position. The second cylinder 10 extends, and at the same time, the drive motor starts, driving the mechanical clamping hand 12 and the base nut to rotate a few turns, so that the nut part is pre-assembled on the screw, avoiding loosening during transportation after assembly, which would affect subsequent tightening assembly. After that, the above components are reset for the next operation.
[0019] 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.
