Description

Multi-degree-of-freedom type washing machine shell overturning device

Technical Field

The utility model relates to the technical field of washing machine production lines, in particular to a multi-degree-of-freedom type washing machine shell overturning device.

Background

The housing of the washing machine is typically manufactured by a manufacturing process such as plastic injection molding (Injection Molding) or metal stamping (METAL STAMPING).

The housing of a washing machine is typically made up of several parts, including a front panel, a rear panel, side panels, a door, a control panel, etc. Each part has its specific function and shape so as to meet the performance and appearance requirements of the washing machine. On the production line, these different parts need to be turned over and adjusted frequently to ensure that they fit correctly and to adapt to the internal parts of the washing machine, thus achieving a complete assembly of the washing machine. Specific:

Each portion must be precisely shaped and sized to mate with the other portions to ensure that the housing is assembled together seamlessly. This requires that minor rotation or adjustment may be required during assembly to eliminate any misalignment or mismatch. The washing machine housing must also accommodate internal components such as motors, pumps, sensors, plumbing, etc. This may require an opening or fitting in the bottom or side of the housing to ensure that these internal components are properly installed and connected.

In a conventional washing machine production line, in order to ensure the correct installation of the components, if the angle of the casing of the washing machine in the previous process does not match the current station requirement, a special manual overturning post is usually required. The task of this post is to manually carry out the washing machine housing and turn over the adjustment, in order to meet the needs of the next process. This conventional mode has the following technical problems:

(1) Time and effort are wasted: manual inversion posts typically require physical labor from an operator to invert the washing machine housing from one angle to another. This is not only time consuming and laborious, but can also cause physical fatigue and potential health problems for the operator.

(2) High labor intensity: the process of manually flipping and adjusting the housing may result in high operator effort, especially during continuous operation, which may adversely affect the physical health of the operator.

(3) Instability: depending on manual flipping and adjustment of the housing, the stability and consistency of the housing may be inferior to automated methods, which may lead to assembly errors or unstable product quality.

For this purpose, a multi-degree-of-freedom washing machine housing turning device is proposed.

This function is critical for angular adjustment on the assembly line, as different orientations may be required for different models of washing machine housings. By this mechanism, the assembly line can precisely control the angle of the washing machine housing to ensure that it is properly aligned with other components without adding human intervention. This contributes to an improvement in production efficiency and assembly quality while reducing the labor intensity of manual operations.

If a production line device is mounted at the rear parts of the frame 1 and the step roller 4, automatic carrying and overturning adjusting functions can be realized.

Specific: the principle of this embodiment is that the servo motor drives the driven wheel (step roller 4) through the driving wheel and sprocket assembly 304. When the servo motor is started, the drive wheel drives the sprocket assembly 304, thereby rotating the step roller 4. The rotation of the step roller 4 serves to provide driving adjustment, changing the position and orientation of the L-shaped frame 2. The step roller 4 may also receive the washing machine outer housing and guide it into position for further automated processing at the final stage of the process.

It will be appreciated that in this embodiment: the functionality of this embodiment is primarily to provide highly automated handling and flip adjustment functions.

Summarizing, aiming at the related problems in the prior art, the specific embodiment is based on the multi-degree-of-freedom washing machine shell overturning device provided by the invention, and the following technical means or characteristics are adopted to realize solving:

(1) Time and labor consuming solution: in the conventional art, a manual overturning post is required to be arranged in front of each station to manually heave and overturn the shell of the washing machine, which consumes a great deal of manpower and time. The technology of the embodiment adopts equipment such as a servo motor, a telescopic cylinder 502 and the like, and can realize automatic shell overturning and adjustment. The precise control of the servo motor and the V-or inverted V-arrangement of the telescopic cylinder 502 increases the range of motion, thereby reducing manual intervention and greatly shortening assembly time.

(2) Solving the high labor intensity: in the conventional art, manual operation requires carrying and turning the heavy duty washing machine housing, which causes a certain pressure to the physical health of the worker. The technique of this embodiment employs an automated servo cylinder and vacuum chuck 504, eliminating most of the manual labor and reducing the labor intensity of workers. The servo cylinder and vacuum chuck 504 can precisely control and stabilize the position of the housing, reducing the burden on the worker.

(3) Solution of instability: in the conventional art, the manual overturning and adjustment of the housing is prone to instability, which may lead to inaccurate positioning and assembly instability of the housing. The technique of the present embodiment employs servo motors, telescoping cylinders 502, and other automated components that provide high precision motion control and angular adjustment. The stable overturning and moving of the shell can be realized through the cooperative work of the universal joint coupling 503, the chain wheel assembly 304, the step roller 4 and other elements. This improves the accuracy and stability of the assembly.

The above examples merely illustrate embodiments of the utility model that are specific and detailed for the relevant practical applications, but are not to be construed as limiting the scope of the utility model.
