[0035] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a washing machine casing inspection device for detecting whether the dimensions of the washing machine casing meet requirements. The inspection device includes a casing inspection platform 1, a casing transfer mechanism 2, and a scanning mechanism 3. The casing inspection platform 1 includes a casing inspection drive assembly 11 and a casing support platform 12. The casing inspection drive assembly 11 drives the casing support platform 12 to rotate. The casing transfer mechanism 2 includes a casing transfer drive assembly 21 and a casing transfer clamping assembly 22. The casing transfer drive assembly 21 drives the casing transfer clamping assembly 22 to move, causing the casing transfer clamping assembly 22 to clamp the finished casing from the washing machine casing processing production line and place it onto the casing support platform 12. The scanning mechanism 3 is disposed on the side of the casing support platform 12. The scanning mechanism 3 is used to acquire the position coordinates of the casing placed on the casing support platform 12 and to obtain the dimensions of the casing based on the acquired position coordinates.

[0036] The washing machine casing testing device provided in this embodiment includes a casing transfer mechanism 2 for clamping the completed casing from the washing machine casing processing production line and placing it on the casing support platform 12 for testing. This testing device is independent of the washing machine casing processing production line and does not occupy the production cycle of the washing machine casing processing production line. The casing support platform 12 rotates and the scanning mechanism 3 cooperates to obtain the position coordinates of the casing placed on the casing support platform 12, and obtains the size of the casing based on the obtained position coordinates. This testing device is compatible with the size testing of various casing models and is not affected by the washing machine casing processing production line.

[0037] In some embodiments, such as Figure 3 and Figure 4As shown, the casing inspection platform 1 also includes a casing inspection base 16. The casing support platform 12 is rotatably mounted on the casing inspection base 16. The casing inspection drive assembly 11 includes a drive motor 111 and a transmission assembly 112 mounted on the casing inspection base 16. The drive motor 111 is connected to the casing support platform 12 through the transmission assembly 112, improving the stability of the drive motor 111 driving the casing support platform 12 to rotate. Optionally, the transmission assembly 112 includes a reducer, or the transmission assembly 112 is a gear transmission structure; no specific limitation is made here. The drive motor 111 can be a servo motor, which has good drive stability.

[0038] In some embodiments, the surface of the housing support platform 12 is provided with a housing placement area 121 for placing a housing. Three columns 13 are spaced apart along the edge of the housing support platform 12. Each column 13 and the surface of the housing support platform 12 surrounding the housing placement area 12 are provided with marker points 14. The marker points 14 are used by the scanning mechanism 3 to scan and locate the housing placed in the housing placement area 121. The marker points 14 on the three columns 13 and the marker points 14 on the housing support platform 12 form a spatial coordinate system, enabling the scanning mechanism 3 to obtain the position coordinates of the housing in the housing placement area 121. Multiple marker points 14 are provided on both the three columns 13 and the housing support platform 12. The marker points 14 are points that can be identified by the scanning mechanism 3. The structure of the marker points 14 is determined according to the type of scanning mechanism 3, and is not specifically limited here.

[0039] Optionally, the outer casing placement area 121 is rectangular, with positioning elements 15 on three sides of the outer casing placement area 121, and three pillars 13 arranged around the three sides of the outer casing placement area 121 with positioning elements 15. In the initial state of the testing equipment, the side without positioning elements 15 faces the outer casing transfer mechanism 2, so that the outer casing transfer mechanism 2 can place the outer casing in the outer casing placement area 121, and the pillars 13 will not interfere with the outer casing transfer mechanism 2. The positioning elements 15 are used to ensure that the outer casing placed in the outer casing placement area 121 is within a preset range, without causing too much deviation, so that the scanning mechanism 3 can obtain accurate data. One side of the outer casing placement area 121 is not provided with positioning elements 15, so that the outer casing placement area 121 can hold outer casings of different models, making the testing equipment compatible with the detection of the size of various models of outer casings, and unaffected by the washing machine outer casing processing production line.

[0040] Optionally, the positioning element 15 is slidably disposed on the housing support platform 12 along the direction close to the housing placement area 121. The housing support platform 12 is provided with a locking element for positioning the positioning element 15 on the housing support platform 12. The position of the positioning element 15 is adjustable to expand the space enclosed between the positioning elements 15 disposed on the three sides of the housing placement area 121, so that the testing equipment can be compatible with the testing of the size of various housing models.

[0041] In some feasible embodiments, the positioning member 15 is provided with an elongated hole, and the locking member is a screw connector. The rod of the screw connector passes through the elongated hole and is screwed to the outer shell support platform 12. The head of the screw connector abuts against the positioning member 15, so that the positioning member 15 is positioned on the outer shell support platform 12. When the screw connector does not lock the positioning member 15, the positioning member 15 can slide relative to the outer shell support platform 12 along the length direction of the elongated hole under the limiting action of the screw connector.

[0042] In other feasible embodiments, the positioning element 15 and the outer shell support platform 12 are slidably connected through a slider and slide rail structure. The positioning element 15 is connected to a linear drive element, such as a cylinder or linear motor. The linear drive element drives the positioning element 15 to slide relative to the outer shell support platform 12 and enables the positioning element 15 to be positioned on the outer shell support platform 12, thereby realizing automatic adjustment of the position of the positioning element 15.

[0043] A detection sensor 17 is set on any side of the positioning member 15 in the housing placement area 121. The detection sensor 17 is used to detect whether a housing is placed in the housing placement area 121. If a housing is detected in the housing placement area 121, the housing detection drive assembly 11 is controlled to drive the housing support platform 12 to rotate. After the housing support platform 12 rotates by a preset angle, the scanning mechanism 3 works.

[0044] In some embodiments, such as Figure 2 As shown, the outer shell transfer drive assembly 21 includes a horizontal transfer drive 211 and a vertical transfer drive 212. The horizontal transfer drive 211 is used to drive the vertical transfer drive 212 to move horizontally between the outer shell support platform 12 and the washing machine outer shell processing production line. The vertical transfer drive 212 is used to drive the outer shell transfer clamping assembly 22 to move vertically, so that the outer shell transfer clamping assembly 22 can clamp or place the outer shell.

[0045] Optionally, the horizontal transfer drive 211 includes a first cylinder that drives the vertical transfer drive 212 to move horizontally. The vertical transfer drive 212 includes a second cylinder that drives the housing transfer clamping assembly 22 to move vertically. Using cylinders reduces the structural cost of the housing transfer drive assembly 21. In other embodiments, the horizontal transfer drive 211 and the vertical transfer drive 212 may be a lead screw and nut structure, a synchronous belt structure, etc., and are not specifically limited here.

[0046] like Figure 2 and Figure 5As shown, the shell transfer clamping assembly 22 includes a clamping drive and two clamping members 221. The clamping drive is used to drive the two clamping members 221 to move closer or further apart to clamp or release the shell. Flexible contact members 222 are provided on both sides of the two clamping members 221 facing each other. The flexible contact members 222 are used to contact the shell to avoid the clamping members 221 from making hard contact with the shell and damaging the shell.

[0047] In some feasible embodiments, the flexible contact 222 includes a contact drive 2221 and a mounting plate 2222. The contact drive 2221 is fixed to the clamping member 221, and the mounting plate 2222 is connected to the contact drive 2221 and positioned on one side facing each other of the two clamping members 221. Each side of the two mounting plates 2222 has a suction cup 2223. The contact drive 2221 drives the mounting plate 2222 connected to it to move towards or away from the other mounting plate 2222. The suction cup 2223 enables flexible clamping of the shell, and during shell transfer, the suction cup 2223 increases the clamping force of the shell transfer clamping assembly 22, thereby improving the stability of the shell transfer clamping assembly 22. The suction cup 2223 can be a vacuum suction cup, in which the suction cup 2223 is evacuated to adsorb the shell during clamping. In addition, the contact drive 2221 drives the mounting plate 2222 to move, thereby reducing the distance between the two mounting plates 2222. The distance between the two mounting plates 2222 can be adjusted a second time according to the size of the housing to achieve stable clamping of the housing.

[0048] In some other feasible methods, the flexible contact includes an elastic element, one end of which is connected to the clamping element, and the other end of which is connected to a contact plate. The contact plate is used to abut against the housing to be clamped, thereby achieving flexible clamping of the housing. The elastic element can be compressed, and the position of the contact plate can be adjusted according to the size of the housing.

[0049] In some embodiments, see continue to see Figure 1 As shown, the scanning mechanism includes an optical tracking 3D scanning mechanism 31, which comprises a scanner 311 and an optical tracker 312. Both the scanner 311 and the optical tracker 312 are disposed on the side of the housing support platform 12. The scanner 311 is used to acquire the position coordinates of the housing placed on the housing support platform 12, and the optical tracker 312 is used to acquire the dimensions of the housing based on the position coordinates acquired by the scanner 311. Exemplarily, the optical tracking 3D scanning mechanism 31 is an intelligent optical tracking 3D scanner equipped with multiple cross-shaped laser lines. It has a fast scanning speed, can quickly acquire three-dimensional data of the object's surface, and has high scanning accuracy, enabling it to acquire detailed information about the object's surface. The structure of the optical tracking 3D scanning mechanism 31 is prior art and will not be described in detail here.

[0050] The scanning mechanism 3 also includes a multi-degree-of-freedom robotic arm 32, which is fixedly mounted on the side of the housing support platform 12. A scanner 311 is mounted at the end of the robotic arm 32. The robotic arm 32 drives the scanner 311 to rotate in coordination with the housing support platform 12, acquiring data information from different positions on the housing. The structure of the robotic arm 32 is existing technology and will not be described in detail here.

[0051] like Figure 6 As shown, the scanning mechanism 3 also includes a bracket 33, and an optical tracker 312 is mounted on the bracket 33. The position of the optical tracker 312 on the bracket 33 is such that the housing detection platform 1 and the scanning mechanism 3 are within the visual range that the optical tracker 312 can capture.

[0052] When using the testing device for the washing machine casing provided in this embodiment, the following steps are included:

[0053] Step 1: The outer shell transfer drive assembly 21 drives the outer shell transfer clamping assembly 22 to clamp the processed outer shell on the washing machine outer shell processing production line and transfer the outer shell to the outer shell placement area 121 on the outer shell carrying platform 12;

[0054] Step 2: After detecting that there is a shell in the shell placement area 121, control the shell detection drive assembly 11 to drive the shell support platform 12 to rotate to a preset angle;

[0055] Step 3: Control the scanning mechanism 3 to obtain the position coordinates of the shell, and obtain the size of the shell based on the obtained position coordinates. After the scanning mechanism 3 has collected the position coordinates of different sides of the shell, the size detection of one shell is completed.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
