The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0020] like Figure 1 and Figure 2 The wheel hub pre-shipment traceability marking mechanism shown mainly includes a supporting component 1, a bidirectional motion component 2, a marking moving unit 3, and a laser marking head 4.
[0021] The support assembly 1 includes a support frame and a support platform 15 mounted on top of the support frame. Specifically, the support assembly 1 includes four parallel and spaced support columns 11 (the projections of these four support columns 11 on the ground are located at the four corners of a rectangle or a square), four connecting crossbars 13 mounted on the lower part of two adjacent support columns 11 (therefore there are four connecting crossbars 13), support feet 12 mounted on the bottom of each support column 11, and four reinforcing crossbars 14 mounted on the upper part of two adjacent support columns 11 (therefore there are also four reinforcing crossbars 14, which correspond one-to-one with the connecting crossbars 13 and are located above the connecting crossbars 13), so that the support platform 15 is mounted on top of the four support columns 11 and supported on the reinforcing crossbars 14, thereby achieving strong support for the support platform 15.
[0022] The bidirectional motion assembly 2 includes a first linear motion module 21 mounted on a support platform 15, a first adapter plate 22 slidably mounted on the first linear motion module 21 (since the first linear motion module 21 has a slider, the first adapter plate 22 is mounted on the slider, so that when the first linear motion module 21 is working, the slider can drive the first adapter plate 22 to move relative to the first linear motion module 21, so that the first adapter plate 22 is slidably mounted on the first linear motion module 21; the same applies below), and a support frame 2 mounted on the first adapter plate 22. 3. A second linear motion module 24 mounted vertically on the support frame 23 and a second adapter plate slidably mounted on the second linear motion module 24 (the connection method between the second adapter plate and the second linear motion module 24 is the same as above); In this embodiment, the first linear motion module 21 is set perpendicular to the hub conveyor line, so that the first adapter plate 22 can approach or move away from the aforementioned hub conveyor line, and ultimately the second adapter plate can move in two directions (at this time, the movement range of the first adapter plate 22 and the second adapter plate is large).
[0023] The marking moving unit 3 includes a receiving frame mounted on the second adapter plate, an X-axis moving component 33 mounted within the receiving frame, and a Z-axis moving component 34 mounted on the X-axis moving component 33 and located within the receiving frame. Specifically, the receiving frame includes a vertically arranged carrier plate 32 mounted on the second adapter plate and a circumferential enclosure 31 (i.e., a hollow square frame) mounted on the circumference of the carrier plate 32 and forming a accommodating space between the carrier plate 32 and the circumferential enclosure 31.
[0024] In this embodiment, the X-axis moving assembly 33 includes a first slide rail 331 (the first slide rail 331 is perpendicular to the first linear moving module 21) mounted horizontally on the carrier plate 32, at least one first slider 332 slidably mounted on the first slide rail 331, a third adapter plate 333 mounted on the first slider 332, a first pulley (not shown in the figure; for example, a mounting shaft perpendicular to the carrier plate 32 can be mounted on the carrier plate 32 via a bearing, and the first pulley can be fitted onto the mounting shaft), a first motor (not shown in the figure, i.e., the first motor is mounted on the surface away from the peripheral enclosure 31, and it has a first output shaft) mounted on the outer surface of the carrier plate 32 and with its first output shaft passing through the carrier plate 32), a second pulley mounted on the first output shaft, and a first belt wound around the first pulley and the second pulley. The first belt is connected to the third adapter plate 333. Thus, when the first motor is working, the third adapter plate 333 can be driven to slide on the first slider 332 via the first belt.
[0025] The Z-axis moving assembly 34 includes a second slide rail 340 mounted vertically on a third adapter plate 333, a second slider 341 slidably mounted on the second slide rail 340, a fourth adapter plate 342 mounted on the second slider 341, a third pulley 344 rotatably mounted on the third adapter plate 333 (mounted in the same manner as above), a second motor (the second motor has a second output shaft) mounted on the inner surface of the third adapter plate 333 and having its second output shaft passing through the third adapter plate 333, a fourth pulley mounted on the second output shaft, and a second belt 343 wound around the third pulley 344 and the fourth pulley. The second belt 343 is connected to the fourth adapter plate 342. Thus, when the second motor is working, the fourth adapter plate 342 can be driven to slide on the second slider 341 via the second belt 343.
[0026] The laser marking head 4 is mounted on the Z-axis moving assembly 34, allowing it to perform large (non-precision) and small (precision) movements under the drive of the aforementioned structure. This enables it to precisely move to the side of the wheel hub for marking, resulting in high reliability, stability, and accuracy. The laser marking head 4 can be a conventional one, such as the one disclosed in Chinese invention patent application number 202410804194.4.
[0027] In this embodiment, the first linear motion module 21 and the second linear motion module 24 can be independently implemented using existing conventional methods (such as those disclosed in Chinese Invention Patent Application No. 202310602533.6) to achieve their own automated control. Furthermore, a PLC controller (Mitsubishi FX2N series-MT model) can be added to connect to the first motor and the second motor (both are conventional bidirectional stepper motors). This allows for automated control of the first and second motors via the PLC controller, improving the automation level and marking efficiency of the entire wheel hub pre-shipment traceability marking mechanism.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
