Description

Technical Field

[0001] This utility model relates to the field of washing machine manufacturing technology, and more specifically, to a dual-station washing machine drum assembly machine. Background Technology

[0002] As an essential appliance in modern households, the manufacturing quality of the washing machine's core component—the drum—directly affects the machine's performance, noise level, and lifespan. During the production and assembly process, the drum undergoes multiple inspections (such as appearance, roundness, and assembly dimensions checks) and the installation of components (such as counterweights, dampers, sensors, and heating elements).

[0003] Currently, the industry largely relies on traditional fixed workbenches for the aforementioned operations on rollers. During operation, operators must manually drag or rotate the heavy rollers to change their circumferential angle. This traditional operating mode has many drawbacks: First, it is inefficient. The rollers are large and heavy, making manual rotation extremely labor-intensive, and precise angle positioning is difficult, resulting in excessively long operation times at each station, becoming a bottleneck in the production line. Second, it poses a high risk to product quality. Manually dragging metal rollers on rough workbenches easily causes scratches and wear to the paint film or surface treatment on the roller's outer wall, creating secondary defects, affecting product appearance quality, and even causing corrosion. Furthermore, inaccurate manual positioning can lead to deviations in the installation position of parts, affecting assembly quality. Finally, it results in a poor ergonomic experience. Repetitive heavy physical labor not only poses a huge challenge to the operator's physical fitness but also easily leads to occupational health problems such as muscle strain, and there are safety hazards such as disorganized tool placement and cramped operating space. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides a dual-station washing machine drum assembly machine, comprising a frame, a cantilever support mounted on the frame, a rotating frame assembly mounted on the cantilever support, and a first drive unit for driving the rotating frame assembly to move vertically up and down. The rotating frame assembly includes a connecting plate, a rotating disk, and a second drive unit. The connecting plate is connected to the output end of the first drive unit, and the second drive unit is connected between the connecting plate and the rotating disk. The second drive unit drives the rotating disk to rotate circumferentially relative to the connecting plate. A rotating seat is rotatably mounted on the frame, positioned directly below the rotating disk and used for detachably mounting an external washing machine drum. The rotating disk is provided with a transmission block for driving the washing machine drum to rotate, and the washing machine drum is provided with a corresponding engaging groove. This utility model has a simple structure and low production cost. By driving the washing machine drum to rotate synchronously through the rotating disk, manual rotation is eliminated, resulting in a high degree of automation. This not only significantly reduces the labor intensity of operators but also effectively improves the consistency of the assembly process and product quality.

[0005] Optionally, multiple transmission blocks are distributed at equal intervals in a ring along the circumference of the rotating disk, and multiple slots are distributed at equal intervals in a ring along the circumference of the washing machine drum, with each transmission block corresponding to one of the slots.

[0006] Optionally, the first drive unit includes a cylinder, the output end of the first drive unit is a telescopic rod, the lower end of the telescopic rod is fixedly connected to the upper side of the connecting plate, and the second drive unit includes an electric rotary table connected to the lower side of the connecting plate, the rotation output end of the electric rotary table is fixedly connected to the rotary disk.

[0007] Optionally, the cantilever bracket is provided with a mounting plate, the mounting plate is provided with a guide sleeve, and the connecting plate is provided with a guide post extending in the vertical direction, the guide post and the guide sleeve being slidably engaged.

[0008] Optionally, the mounting plate is in the shape of an equilateral triangle, and three guide sleeves are provided, each located at one of the three apex corners of the mounting plate. Three guide posts are provided, each corresponding to one of the guide sleeves.

[0009] Optionally, the slot opening is provided with an arc-shaped guide slope to facilitate the insertion of the transmission block.

[0010] Optionally, the rotating disk is provided with a plurality of stress dispersion holes, which are distributed in a ring at equal intervals.

[0011] Optionally, a bearing is provided between the rotating seat and the frame, the rotating seat is coaxially arranged with the rotating disk, a connecting shaft is provided at the bottom of the washing machine drum, and a plug groove is provided on the rotating seat for detachable insertion with the connecting shaft. An annular guide slope is provided at the opening of the plug groove to facilitate the insertion of the connecting shaft.

[0012] Optionally, the frame is provided with a tool box and a screwdriver mounting sleeve. The tool box contains screws, and the screwdriver mounting sleeve is detachably connected to an electric screwdriver.

[0013] Optionally, two rotating frame assemblies are symmetrically distributed on the cantilever bracket, and two first drive units are symmetrically distributed and connected to the rotating frame assemblies.

[0014] Compared to existing technologies, the dual-station washing machine drum assembly machine of this utility model has a simple structure and low production cost. It drives the washing machine drum to rotate synchronously via a rotating disc, eliminating the need for manual rotation and achieving a high degree of automation. This not only significantly reduces the operator's labor intensity but also effectively improves the consistency of the assembly process and product quality. Multiple transmission blocks are evenly distributed in a ring along the circumference of the rotating disc, and multiple slots are evenly distributed in a ring along the circumference of the washing machine drum. Each transmission block corresponds to one slot. The engagement of multiple transmission blocks and slots forms a multi-tooth engagement power transmission system. When the rotating disc rotates, power is evenly transmitted to the washing machine drum through multiple contact points, avoiding slippage, asynchrony, or stress concentration problems that may occur with single-point transmission, ensuring that the drum can rotate strictly synchronously and smoothly with the rotating disc.

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0027] See Figures 1-8 This utility model provides a dual-station washing machine drum assembly machine, including a frame 1, a cantilever support 2 on the frame 1, a rotating frame assembly on the cantilever support 2, and a first drive unit for driving the rotating frame assembly to move up and down vertically. The rotating frame assembly includes a connecting plate 31, a rotating disk 32, and a second drive unit. The connecting plate 31 is connected to the output end of the first drive unit, and the second drive unit is connected between the connecting plate 31 and the rotating disk 32. The second drive unit is used to drive the rotating disk 32 to rotate circumferentially relative to the connecting plate 31. A rotating seat 4 is rotatably mounted on the frame 1. The rotating seat 4 is located directly below the rotating disk 32 and is used for detachably installing an external washing machine drum 5. A transmission block 321 for driving the washing machine drum 5 to rotate is provided on the rotating disk 32, and a slot 501 corresponding to and engaging with the transmission block 321 is provided on the washing machine drum 5. This utility model has a simple structure and low production cost. By driving the washing machine drum to rotate synchronously through the rotating disk, no manual rotation is required, resulting in a high degree of automation. This not only significantly reduces the labor intensity of the operator but also effectively improves the consistency of the assembly process and product quality.

[0028] Specifically, this utility model integrates a liftable and rotatable drive unit through a cantilever bracket, driving the rotating disk and the lower drum to rotate synchronously, thus achieving the rotation requirements of the washing machine drum during inspection and assembly, improving work efficiency, and effectively shortening the production cycle. The drive unit uses a locking transmission method between the transmission block on the rotating disk and the drum slot, ensuring direct and reliable power transmission and avoiding scratches and wear on the drum's side surface caused by traditional friction transmission, effectively guaranteeing the product's appearance quality. The operating steps are as follows: First, place the washing machine drum 5 to be inspected or assembled on the rotating base 4. Then, control the first drive unit to move the rotating frame assembly downwards via an external control switch, causing the transmission block 321 to engage with the slot 501. At this point, control the second drive unit to rotate a certain angle and then stop via another external control switch, allowing the washing machine drum 5 to rotate to the angle required by the worker for inspection or assembly. No manual rotation of the washing machine drum 5 is required, making it convenient to use. After inspection or assembly is completed, the first drive unit moves the rotating frame assembly upwards, removes the washing machine drum 5, installs a new washing machine drum 5 to be inspected or assembled, and proceeds to the next cycle.

[0029] See Figure 1 , Figure 2 , Figure 4 and Figure 5 Multiple transmission blocks 321 are evenly distributed in a ring along the circumference of the rotating disk 32, and multiple slots 501 are evenly distributed in a ring along the circumference of the washing machine drum 5. Each transmission block 321 corresponds to one slot 501. The engagement of multiple transmission blocks and slots forms a multi-tooth engagement power transmission system. When the rotating disk rotates, power is evenly transmitted to the washing machine drum through multiple contact points, avoiding slippage, asynchrony, or stress concentration problems that may occur with single-point transmission, ensuring that the drum can rotate strictly synchronously and smoothly with the rotating disk.

[0030] See Figure 1 and Figure 2 The first drive unit includes a cylinder 61, the output end of which is a telescopic rod. The lower end of the telescopic rod is fixedly connected to the upper side of the connecting plate 31. The cylinder uses compressed air as a power source, has a fast operating speed, and can quickly complete the rising and falling of the roller, shortening the operation time and meeting the high efficiency requirements of the production line for cycle time. The second drive unit includes an electric rotary table 62 connected to the lower side of the connecting plate 31. The rotation output end of the electric rotary table 62 is fixedly connected to the rotary disk 32. The structure is compact and the equipment occupies less space.

[0031] See Figure 1 and Figure 2The cantilever bracket 2 is equipped with a mounting plate 7, and the mounting plate 7 is equipped with a guide sleeve 71. The connecting plate 31 is equipped with a guide post 311 extending in the vertical direction. The guide post 311 and the guide sleeve 71 slide in a sliding fit, so that the connecting plate 31 slides smoothly in the vertical direction, improving the success rate of docking between the transmission block and the slot. The mounting plate 7 is in the shape of an equilateral triangle. There are three guide sleeves 71, which are located at the three apex positions of the mounting plate 7. There are three guide posts 311, which correspond one-to-one with the guide sleeves 71. The three guide post and guide sleeve pairs with the equilateral triangle layout form a stable sliding support structure, which further improves the stability of the connecting plate 31 when sliding and is less likely to tilt or other problems during the sliding process.

[0032] See Figure 2 The slot 501 has an arc-shaped guide slope 5011 at the opening to facilitate the insertion of the transmission block 321, which further improves the success rate of docking between the transmission block and the slot. During docking, the worker only needs to rotate the washing machine drum to the angle where the transmission block and the slot can be docked visually, and then accurately dock the transmission block and the slot through the arc-shaped guide slope 5011. The transmission block 321 is made of nylon to avoid damaging the stainless steel washing machine drum.

[0033] See Figure 1 and Figure 2 The rotating disk 32 is provided with a number of stress dispersion holes 322. The stress dispersion holes 322 are distributed in a ring at equal intervals. The ring at equal intervals can evenly disperse the centrifugal stress and thermal stress during rotation, prevent deformation, and improve the stability of operation and structural life. In addition, it can also reduce the weight of the rotating disk, reduce the drive load, and make start-stop faster and more energy-efficient.

[0034] See Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 A bearing 8 is provided between the rotating base 4 and the frame 1. The rotating base 4 and the rotating disk 32 are coaxially arranged. A connecting shaft 502 is provided at the bottom of the washing machine drum 5. The rotating base 4 is provided with a plug groove 401 for detachable insertion with the connecting shaft 502. An annular guide slope 402 is provided at the opening of the plug groove 401 to facilitate the insertion of the connecting shaft 502. The bearing enables the rotating base and the drum to move flexibly and reduce friction. The coaxial design ensures accurate rotational alignment. The plug groove and the annular guide slope facilitate the quick self-alignment and insertion of the connecting shaft, realizing the rapid positioning and installation of the drum.

[0035] See Figure 1 and Figure 3The frame 1 is equipped with a tool box 91 and a screwdriver mounting sleeve 92. The tool box 91 contains screws, and the screwdriver mounting sleeve 92 is detachably connected to an electric screwdriver 93. The screws and electric screwdrivers are centrally stored, enabling fixed-point and convenient access to tools and consumables, reducing the time operators spend searching, avoiding confusion and loss, significantly improving the continuity and efficiency of assembly operations, and ensuring a clean and orderly work site.

[0036] See Figure 1 Two rotating frame assemblies are symmetrically distributed on the cantilever bracket 2, and two first drive units are symmetrically distributed and connected to the rotating frame assemblies; thus realizing a dual-station design, it is possible to achieve simultaneous operation of two rollers and improve production efficiency.

[0037] The dual-station washing machine drum assembly machine of this utility model has a simple structure and low production cost. It drives the washing machine drum to rotate synchronously via a rotating disc, eliminating the need for manual rotation and achieving a high degree of automation. This not only significantly reduces the operator's labor intensity but also effectively improves the consistency of the assembly process and product quality. Multiple transmission blocks 321 are evenly distributed in a ring along the circumference of the rotating disc 32, and multiple slots 501 are evenly distributed in a ring along the circumference of the washing machine drum 5. Each transmission block 321 corresponds to one slot 501. The engagement of multiple transmission blocks and slots forms a multi-tooth engagement power transmission system. When the rotating disc rotates, power is evenly transmitted to the washing machine drum through multiple contact points, avoiding slippage, asynchrony, or stress concentration problems that may occur with single-point transmission, ensuring that the drum can rotate strictly synchronously and smoothly with the rotating disc.
