Description

Technical Field

[0001] The utility model relates to the technical field of equipment foot processing, in particular to an online rejecting mechanism for defective washing machine feet. Background Art

[0002] In the manufacturing process of washing machines, as a key component for the stable placement of washing machines, the quality of feet directly affects the stability and safety of washing machines during use. Among them, the installation accuracy of the foot nut part is an important indicator to measure the quality of feet. If there is a deviation in the installation position of the nut, it may cause problems such as shaking and noise during the operation of the washing machine, and even affect the overall performance and service life of the washing machine. At present, for the detection of defective washing machine feet in the industry, a single infrared range finder is generally used for detection. The single infrared range finder judges whether the foot is qualified by measuring the distance between itself and the foot nut and comparing it with a preset qualified distance range. However, this detection method has obvious limitations. In actual production, in order to meet the needs of different models of washing machines or different application scenarios, it is often necessary to replace foot nuts of different specifications. For existing feet, the threaded support generally remains unchanged, and only the foot nut needs to be installed. However, due to the differences in the size and shape of different nuts, the height of the upper end surface after they are assembled with the threaded support changes. After the nut is replaced, the detection reference of the single infrared range finder will change, resulting in the originally set qualified distance range no longer being applicable. This requires manual re-debugging of the detection part and setting of new qualified parameters. This process not only consumes a lot of time and manpower and increases production costs, but also may cause inaccurate debugging due to human factors during the debugging process, which affects the reliability of the detection result, and thus causes some unqualified feet to flow into the subsequent production links and reduce product quality. Contents of Utility Model

[0003] The objective of the present utility model is to propose an online rejecting mechanism for defective washing machine feet to solve the shortcomings existing in the prior art. When the rejecting device is in use, two infrared range finders are used to face the nut part of the foot, and the product is qualified as long as the two range finders are kept at the same height. Compared with the application of the existing single infrared range finder, even when different nuts are replaced, there is no need to debug the detection part.

[0004] In order to achieve the above objective, the utility model adopts the following technical solution: An online rejecting mechanism for defective bottom feet of washing machines, comprising bottom feet formed by nuts and threaded support feet, further comprising a support base, wherein the upper end of the support base is fixedly connected with a rotating table, the rotating part of the rotating table is fixedly connected with a driving disc, and a plurality of placing seats are installed on the driving disc at equal intervals; a first connecting frame is fixedly connected to the upper end of the right side of the support base, a mounting plate is installed on the rear side of the first connecting frame, infrared range finders are installed on both sides of the mounting plate, and both of the two infrared range finders can simultaneously irradiate the nut of the corresponding bottom foot; a material pushing mechanism, wherein the material pushing mechanism is matched with the two infrared range finders.

[0005] Preferably, the placing seat is composed of a rectangular block and a T-shaped groove penetrating through the rectangular block, and the T-shaped groove is used for placing the bottom foot.

[0006] Preferably, the material pushing mechanism comprises a second connecting frame fixedly connected to the upper end of the support base, an L-shaped plate is fixedly connected to the front side of the second connecting frame, a telescopic cylinder is installed on the left side of the L-shaped plate, and the telescopic end of the telescopic cylinder penetrates through the L-shaped plate and is fixedly connected with a pushing plate.

[0007] Preferably, the height of the lower end face of the pushing plate is higher than the height of the upper end face of the plurality of placing seats.

[0008] Preferably, a defective product discharge channel is installed at the upper end of the support base, and the left side of the defective product discharge channel is arc-shaped and contacts with the side face of the driving disc.

[0009] Preferably, the included angle between the defective product discharge channel and the horizontal plane is 30°.

[0010] Compared with the prior art, the utility model has the following beneficial effects: 1. Two infrared range finders are used to directly detect the nut part of the bottom foot, and the product is judged as qualified if the heights measured by the two range finders are consistent. Compared with the existing single infrared range finder, there is no need to debug the detection part when replacing different nuts, which greatly improves the adaptability and efficiency of detection, and reduces the operation difficulty and cost.

[0011] 2. In the material pushing part, the telescopic cylinder drives the pushing plate to push out defective products at a low speed, and the rotating table can rotate without waiting for the cylinder to retract, which avoids interference between the material pushing and the placing seat, and the pushing plate can move back quickly. This design ensures the detection efficiency, and does not exert a large impact force on defective products, avoiding damage to defective products, which is conducive to subsequent dismantling and reuse.

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 3-4 A defective washing machine foot removal mechanism includes a foot support 1 consisting of a nut and a threaded foot support. Specifically, the nut is threaded onto the threaded foot support. The nut part is specifically composed of a nut and a support ring. In actual products, there may be multiple models with the same threaded foot support but different nut parts. The above are all existing technologies and will not be described in detail here. Reference Figures 1-2 A rotating table 2 is fixedly connected to the upper end of the support base 1. The rotating table 2 is specifically composed of a table body and an internal drive motor, which enables its rotating part to grip and manipulate. The rotating part of the rotating table 2 is fixedly connected to a drive disk 4. Multiple placement seats 3 are installed at equal intervals on the drive disk 4. The placement seat 3 is composed of a rectangular block and a T-shaped groove that penetrates the rectangular block. The T-shaped groove is used to place the feet. Furthermore, the rotating table 2 of this solution can cooperate with existing assembly equipment to realize multi-station assembly work. The inspection part is located in the penultimate step of the station assembly. Specifically, the entire assembly process is as follows: foot loading, nut loading, positioning, tightening, inspection, and unloading. Among them, the upper right side of the support base 1 is fixedly connected to the first connecting frame 6, the rear side of the first connecting frame 6 is installed with the mounting plate 9, and the two sides of the mounting plate 9 are equipped with infrared rangefinders 10, such as ZX1-LD300A61. Both infrared rangefinders 10 can simultaneously illuminate the nuts of the corresponding feet. Furthermore, it also includes a processor (not shown). The system also includes a pushing mechanism, which works in conjunction with two infrared rangefinders 10. The pushing mechanism includes a second connecting frame 8 fixedly connected to the upper end of the support base 1. An L-shaped plate 11 is fixedly connected to the front side of the second connecting frame 8. A telescopic cylinder 12 is installed on the left side of the L-shaped plate 11. The cylinder model can be CDQ2XB32-50DM. It has independent air inlet and outlet ports and valves. In this solution, it can achieve slow extension and rapid retraction. Furthermore, during the assembly of the feet, the defective products that usually occur are that the nuts are not completely aligned with the threaded feet. If a tightening operation is performed, the nuts will tilt. Specifically, in this solution, if the detection heights of the two infrared rangefinders 10 are different, it indicates that this situation has occurred. At this time, the pushing mechanism can be activated. The telescopic end of the telescopic cylinder 12 passes through the L-shaped plate 11 and is fixedly connected to the push plate 5. The lower end of the push plate 5 is higher than the upper end of the multiple placement seats 3. With this structure, during operation, after the telescopic cylinder 12 extends, it pushes the workpiece out and falls into the waste and defective product discharge channel 7. There is no need to wait for it to retract, and the rotary table 2 can start to rotate, which reduces downtime and improves overall efficiency. At this time, the rotation of the placement seat 3 after being pushed will not interfere with the push plate 5. Since the push plate 5 can move back quickly, it will not contact the next placement seat 3 equipped with feet.

[0016] Among them, the upper end of the support base 1 is equipped with a waste product discharge channel 7. The left side of the waste product discharge channel 7 is arc-shaped and contacts the side of the drive disk 4. The angle between the waste product discharge channel 7 and the horizontal plane is 30°.

[0017] In this utility model, the internal drive motor of the rotary table 2 drives its rotating part to rotate, and the rotating part drives the fixedly connected drive disk 4 to rotate. Multiple placement seats 3 rotate accordingly. The T-shaped groove of the placement seat 3 is used to place the feet, realizing the transfer of the feet between different workstations. When the base is rotated to the detection position, the two infrared rangefinders 10 simultaneously illuminate the corresponding nut of the base and transmit the detection data to the processor. If the nut is not fully aligned with the threaded foot support, tightening the foot will cause the nut to tilt. In this case, the two infrared rangefinders 10 will detect different heights, and the processor will determine that the nut is misaligned, thus classifying it as a defective product. When the processor determines that a workpiece is defective, the telescopic cylinder 12 extends, and its telescopic end drives the fixedly connected push plate 5 to move. The push plate 5 pushes the workpiece off the placement seat 3, and the workpiece falls into the waste and defective product discharge channel 7. After the telescopic cylinder 12 extends and pushes the workpiece off, there is no need to wait for it to retract; the rotary table 2 can rotate immediately. At this time, the rotation of the placement seat 3 after being pushed off will not interfere with the push plate 5, and the push plate 5 can quickly move back without contacting the next placement seat 3 equipped with feet. The waste and defective product discharge channel 7 is installed on the upper end of the support base 1. The left side of the waste and defective product discharge channel 7 is arc-shaped and contacts the side of the drive disk 4. The angle between the channel and the horizontal plane is 30°. The defective workpieces pushed out by the push plate 5 are smoothly discharged along the waste and defective product discharge channel 7.

[0018] 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.
