The piston is moved downward by the injection of the pressurized gas, and the extension rod is moved downward synchronously by the downward movement of the piston. When the extension rod moves downward, it will drive the arc-shaped fixing plate downward to fix the main body of the glass observation window. In the above technical solution, the arc-shaped fixing plate is pressed against the observation window for positioning, which will squeeze the raised part of the observation window and easily cause surface wear.

[0019] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.

[0020] like Figures 1 to 6As shown, a washing machine observation window detection device of this embodiment includes a driving component 1, a clamping component 2 and a detection platform 3, wherein the driving component 1 includes a driving part 11 and a pushing part 12, wherein the pushing part 12 is connected to the driving part 11, and the driving part 11 drives the pushing part 12 to move, and the driving part 11 can be a cylinder. In this embodiment, the pushing part 12 includes a limiting groove 121, and the limiting groove 121 is V-shaped, so that the workpiece 10 is limited by the limiting groove 121. The clamping component 2 is located on one side of the pushing part 12 and on the detection platform 3, and the clamping component 2 includes a bottom plate 21, a clamping plate 22 and a limiting component 23, and one end of the clamping plate 22 is connected to the shaft rod 24, so that the clamping plate 22 can be turned over. A limiting component 4 is arranged between the shaft rod 24 and the bottom plate 21, and the limiting component 4 can keep the clamping plate 22 in the open position. The bottom plate 21 is provided with a first through hole 211, and the clamping plate 22 is provided with a second through hole 221. The second through hole 221 is arranged corresponding to the workpiece 10, and the first through hole 221 is arranged corresponding to the hole 31 of the detection platform 3. An air supply assembly is arranged below the detection platform 3, and the air supply assembly is connected to the hole 31. The end of the clamping plate 22 is provided with a locking assembly 25, and the locking assembly 25 is engaged or separated with the bottom plate 21. In the above technical scheme, when the observation window (i.e., the workpiece) is inspected, it is first transmitted to the position of the driving assembly 1 through the conveying device 20, and the conveying device can be a conveyor belt. Then, the driving part 11 drives the pushing part 12 to extend, and the pushing part 12 moves the workpiece 10 toward the clamping assembly 2 until the workpiece 10 is located above the hole 31 and the bottom plate 21; then, the workpiece 10 is pressed down and positioned by the clamping plate 22, and the clamping plate 22 is fixedly connected to the bottom plate 21 by the locking assembly 25, so that the skirt 101 of the workpiece 10 is clamped and positioned. By providing the second through hole 221, the raised portion of the observation window can be exposed through the second through hole. The air flow is introduced into the hole 31 through the air supply assembly to test the sealing of the workpiece 10. The above technical solution can facilitate the positioning of the workpiece without squeezing its transparent raised portion, thereby avoiding wear of the observation window.

[0021] In this embodiment, the limit assembly 4 includes a limit member 41, a spring 42 and a baffle 43. One end of the limit member 41 is connected to the shaft 24, and the other end is provided with a baffle 43. The baffle 43 is located below the bottom plate 21. The spring 42 is sleeved on the limit member 41 and pressed against the baffle 43. The other end of the spring 42 presses against the bottom plate. Figure 2 As shown in the figure, the elastic force of the spring 42 can exert downward pressure on the baffle 43, so that the limiter 41 pulls the shaft 24 to keep the clamping plate 22 in an open state. The end of the clamping plate 22 is provided with a support plate 221, which is inclined. When the clamping plate 22 is opened, the support plate 221 presses against the bottom plate 21, thereby limiting the opening angle.

[0022] In this embodiment, the locking assembly 25 includes a rotating rod 251, a limiting spring 252 and a clamping plate 253. The rotating rod 251 is arranged on the mounting seat 222 of the clamping plate 22. The rotating rod 251 passes through the limiting spring 252 and the clamping plate 253. The limiting spring 252 is located in the mounting seat 222 and presses the clamping plate 253. The limiting spring 252 applies pressure to the clamping plate 253 so that it can press under the bottom plate 21, thereby locking. When it is necessary to release, the rotating rod 251 is rotated to disengage the clamping plate 253 from the bottom plate 21, thereby releasing the locking state.

[0023] In this embodiment, the air supply assembly includes a connecting portion 5, on which an air supply port 51 is provided, and the air supply port 51 is provided with a pressure sensor 52, and the connecting portion 5 is matched with the hole 31. The hole 31 is sealed at the bottom by the connecting portion 5, and the air supply port 51 is connected to the air source through the pressure sensor 52. The air source can be an existing air supply device such as an air compressor. The gas enters the hole 31 through the air supply port 51. The two sides of the hole are sealed by the connecting portion and the workpiece respectively. The pressure sensor 52 is connected to the control module to obtain pressure data, thereby testing the sealing of the workpiece. The connecting portion 5 includes an annular portion 53, which is a hollow structure made of rubber material. The air supply port 51 includes a first air supply end 511 and a second air supply end 512. The second air supply end 512 is connected to the hole 31. The annular portion 53 is connected to the first air supply end 511 through a connecting pipe 54, and the connecting pipe 54 is located in the groove 55 of the connecting portion 5. Through the above technical solution, the airflow enters the hollow annular portion 53 through the first air supply end 511, causing the annular portion 53 to expand, thereby pressing the annular portion 53 against the inner wall of the hole, so that the sealing between the hole and the connecting portion 5 is better. The connecting portion 5 is circular, so as to match the hole.

[0024] A washing machine observation window detection device of the present embodiment can facilitate the positioning of the workpiece without squeezing its transparent protrusion, thereby avoiding wear of the observation window; in addition, it can improve the air supply sealing and improve the detection accuracy.
