Description

Technical Field

[0001] This utility model relates to the technical field of testing tooling, and in particular to a rapid testing device for the back drum of a washing machine. Background Technology

[0002] In the manufacturing process of washing machines, the rear tub is a key structural component that supports core components such as the washing tub and motor. Its dimensional accuracy, appearance integrity, and the accuracy of the assembly holes directly determine the operational stability and service life of the washing machine. Therefore, it is necessary to complete comprehensive quality inspection through a dedicated testing station before leaving the factory.

[0003] Currently, the positioning method for the washing machine back drum inspection station is mostly manual: the operator needs to visually observe the alignment of the edge of the back drum with the station baseline and manually push the back drum to adjust its position. Not only is each positioning time-consuming, but the positioning accuracy also fluctuates greatly due to the operator's experience and visual errors. This causes the detection probe to be unable to accurately align with the detection target point of the back drum, which easily leads to missed detections and false detections, and consequently causes unqualified products to flow into downstream processes. Utility Model Content

[0005] The rapid detection device for the rear drum of a washing machine provided in this application adopts the following technical solution: A rapid detection device for the rear drum of a washing machine includes an operation box, an operation platform inside the operation box, a detection camera connected to the top of the operation box, a base plate fixedly mounted above the operation platform, a tray placed on the base plate, a positioning post for positioning the inner ring of the rear drum of the washing machine connected to the tray, a first positioning plate connected to the front end of the base plate, a second positioning plate slidably mounted behind the base plate, and third positioning plates provided on the left and right sides of the base plate.

[0006] Preferably, a weighing module is connected to the operating platform, the base plate is connected to the weighing module, and the base plate is located above the weighing module.

[0007] Preferably, a first linear module is connected to the operating table. The first linear module is arranged in a direction perpendicular to the side wall of the base plate. The second positioning plate is connected to the movable seat of the first linear module. The second positioning plate is arranged in a direction parallel to the corresponding side wall of the base plate.

[0008] Preferably, a second linear module is connected to the operating table. The second linear module is arranged in a direction perpendicular to the side wall of the base plate. The third positioning plate is connected to the movable seat of the second linear module. The third positioning plate is arranged in a direction parallel to the corresponding side wall of the base plate.

[0009] Preferably, the base plate has a groove for the third positioning plate to be pushed in, and the tray has a positioning groove for the third positioning plate to be pushed in.

[0010] Preferably, the tray is connected to a handle, and the handle is provided on each of the opposite sides of the tray.

[0011] In summary, this application includes the following beneficial technical effects: This utility model provides a rapid detection device for the rear drum of a washing machine. Through a combined positioning structure of positioning columns, multiple positioning plates, and linear modules, it achieves multi-dimensional precise positioning: the positioning columns first limit the position of the inner ring of the washing machine's rear drum, preventing the rear drum from shifting on the tray; the first positioning plate and the second positioning plate cooperate to precisely limit the front-back position of the tray on the base plate, and the third positioning plates on both sides simultaneously limit the left-right position of the tray on the base plate. The entire process eliminates the error caused by manual visual judgment and manual adjustment, resulting in high positioning accuracy. This ensures that the detection camera can accurately align with the detection target point of the rear drum, effectively reducing the rate of missed detections and false detections, and guaranteeing the detection quality. Thus, it achieves the effect of improving the positioning efficiency and accuracy of the washing machine rear drum detection station. Attached Figure Description

[0016] This application discloses a rapid detection device for the rear drum of a washing machine. (Refer to...) Figure 1 , Figure 2 and Figure 3 The washing machine rear tub rapid detection device includes an operation box 1, an operation platform 11 inside the operation box 1, a detection camera 2 connected to the top of the operation box 1, the detection camera 2 being interconnected with an external detection system, a base plate 3 fixedly installed above the operation platform 11, a tray 4 placed on the base plate 3, a positioning post 41 for positioning the inner ring of the washing machine rear tub connected to the tray 4, a first positioning plate 31 connected to the front end of the base plate 3, a second positioning plate 5 slidably installed behind the base plate 3, and a third positioning plate 6 provided on the left and right sides of the base plate 3.

[0017] The operating table 11 is connected to a weighing module 111, and the base plate 3 is connected to the weighing module 111. The base plate 3 is located above the weighing module 111. On the one hand, it can fix the base plate 3, and on the other hand, it can collect the weight data of the washing machine's rear tub and tray 4 in real time while performing positioning detection. By comparing the weight with the standard weight range through an external system, rear tubs with abnormal weight can be screened out in advance. If there are material defects or missing parts, such unqualified products are prevented from entering the subsequent visual inspection stage, reducing the cost of ineffective detection and further improving the integrity and efficiency of the inspection process.

[0018] The control panel 11 is connected to a first linear module 112, which is arranged in a direction perpendicular to the side wall of the base plate 3. The second positioning plate 5 is connected to the movable seat of the first linear module 112, and is arranged in a direction parallel to the side wall of the corresponding base plate 3.

[0019] The control panel 11 is connected to a second linear module 113, which is arranged in a direction perpendicular to the side wall of the base plate 3. The third positioning plate 6 is connected to the movable seat of the second linear module 113, and is arranged in a direction parallel to the side wall of the corresponding base plate 3.

[0020] By using a linear module to automatically drive the positioning plate, the positioning time per cycle is shortened and the positioning efficiency is improved.

[0021] The base plate 3 has a groove for the third positioning plate 6 to be pushed in, and the tray 4 has a positioning groove for the third positioning plate 6 to be pushed in. The groove of the base plate 3 and the positioning groove of the tray 4 can guide the third positioning plate 6 to be pushed in accurately, thereby improving the structural stability.

[0022] The pallet 4 is connected to a handle 42, with one handle 42 on each of the opposite sides of the pallet 4. The pallet 4 is designed to work with the handles 42 for easy and quick handling.

[0023] The entire positioning process only requires two simple actions: placing the rear bucket and moving the pallet. Subsequent positioning and detection are all automated, reducing reliance on operator experience and minimizing human error.

[0024] The implementation principle of a rapid detection device for the rear drum of a washing machine according to an embodiment of this application is as follows: 1. Device initialization preparation Turn on the power to the control box 1 and check whether the detection camera 2, weighing module 111, first linear module 112, and second linear module 113 are in normal working condition, such as the camera lens is clean, the module runs smoothly without jamming, and the weighing data is zero. 2. Washing machine rear drum pre-positioning and tray 4 loading The operator takes the back tub of the washing machine to be tested, with the open end of the back tub facing down, and aligns it with the positioning post 41 on the tray 4. Usually, 3-4 posts are set and evenly distributed along the center of the tray 4. The operator slowly inserts the tub into the outside of the positioning post 41. Adjust the position of the rear bucket to ensure that the inner ring of the rear bucket fits tightly with the positioning post 41 without significant shaking. After the rear bucket is positioned on the tray 4, the position of the rear bucket on the tray 4 is initially fixed. 3. Pallet handling and initial positioning The operator holds the handles 42 on both sides of the pallet 4 with both hands and steadily moves the pallet 4 containing the rear bucket to the top of the base plate 3. Slowly lower the tray 4 so that the bottom of the tray 4 is in contact with the surface of the base plate 3. At the same time, push the front end of the tray 4 towards the first positioning plate 31 until the front end of the tray 4 is completely in contact with the first positioning plate 31, thus completing the initial front and rear positioning of the tray 4. At this time, the front and rear position of the tray 4 on the base plate 3 is roughly determined. 4. Automated and precise positioning When the positioning control command is initiated, the external control system drives the first linear module 112 to work: the movable seat of the first linear module 112 drives the second positioning plate 5 to move in a direction perpendicular to the front and rear side walls of the base plate 3, i.e., in the forward direction; When the second positioning plate 5 moves to fit tightly against the rear end of the tray 4, the first linear module 112 stops operating. At this time, the first positioning plate 31 and the second positioning plate 5 together clamp the tray 4, completely limiting the front and rear position of the tray 4. Subsequently, the control system drives the second linear module 113 to work, causing the corresponding third positioning plate 6 to move along the direction perpendicular to the left and right side walls of the base plate 3; During the movement, the third positioning plate 6 is embedded in the groove of the base plate 3 and simultaneously embedded in the positioning groove of the tray 4 until both sides of the third positioning plate 6 are tightly fitted with the left and right side walls of the tray 4. The second linear module 113 stops running. At this time, the two sides of the third positioning plate 6 clamp the tray 4, completely limiting the left and right position of the tray 4. After positioning is completed, the weighing module 111 collects the total weight data of the pallet 4 and the rear bucket in real time and transmits the data to the external system to complete the preliminary weight detection. 5. Rear bucket inspection and data processing After the positioning is confirmed to be correct, the inspection camera 2 is activated to take multi-angle pictures of the appearance of the washing machine's rear drum, such as surface cracks and dents; and the assembly holes, such as hole position and hole diameter. The inspection camera 2 transmits the captured image data to an external inspection system. The system compares the image data with the preset standard back bucket parameters using an image algorithm to determine whether the appearance and hole positions of the back bucket are up to standard. At the same time, the external system combines the weight data transmitted by the weighing module 111 to determine whether the weight of the rear bucket is within the standard range. If the weight is abnormal, it is directly determined to be a defective product. The system automatically generates an inspection report, records the pass / fail results and key data, such as positioning accuracy, weight value, and location of defects, and displays the results on the display screen of the operation box 1. Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
