The marking head 620 can be an inkjet device, a laser head or a mechanical marking device, and the specific form is determined according to the material and marking requirements of the workpiece 400 to be measured. When the marking method is inkjet, the inkjet print head is provided in the marking head, and the mark is formed on the marking plate 210 by spraying ink. When the marking method is mechanical marking, a seal is fixed on the marking head 620, and the mark is formed on the marking plate 210 by the seal. The seal can quickly leave a mark, and the seal is easy to erase, facilitating the repeated use of the marking plate 210 of the carrier 200, and ensuring the clarity and accuracy of the marking position.

[0057] In this embodiment, the marking device 600 can also be provided with a transverse horizontal movement mechanism 640, which slides on the surface of the bracket 610, so that the driving mechanism 630 and the marking head 620 can move away from or approach the carrier 200, thereby marking the marking plate 210 on the carrier 200 of different sizes.

[0058] In this embodiment, the driving mechanism 630 is electrically connected with the control device 700, and is responsible for driving the marking head 620 to move up and down along the bracket 610. The main function of the driving mechanism 630 is to control the contact position of the marking head 620 with the marking plate 210 during marking, so as to ensure that the marking head 620 marks at the specified position. The driving mechanism 630 can be an electric motor, a pneumatic cylinder or a stepping motor. The driving mechanism 630 communicates with the control device 700 through electrical signals, and accurately controls the movement speed, position and stop position of the marking head 620. Through precise control, the marking head 620 can accurately mark at the specified position of the marking plate 210, without deviation or repeated marking.

[0059] Referring to Figure 5 As shown in the figure, in an embodiment, the testing device 500 is provided with multiple detection probes 510 for testing multiple workpieces 400 at the same time; the marks on the mark plate 210 are also multiple, and the marking heads 620 correspond to the marks.

[0060] In this embodiment, the testing device 500 is the core part of the entire device for testing the performance or quality of the workpieces 400. In order to improve the detection efficiency, the testing device 500 in this embodiment is equipped with multiple detection probes 510, which can simultaneously test all the workpieces 400 on a carrier 200. This design greatly improves the production efficiency, especially suitable for batch production scenarios. The testing device 500 obtains the test data of each probe in real time through intelligent control, and transmits the detection results to the control device 700.

[0061] In a preferred embodiment, each detection probe 510 is automatically calibrated by the control device 700 before starting work, ensuring good contact between the probe and the workpiece 400 and ensuring the accuracy of the measurement data.

[0062] In this embodiment, the mark plate 210 is provided with multiple mark areas, each of which corresponds to a workpiece 400. These mark areas are designed to be unique (for example, through a digital number) so as to correspond one by one with the workpieces 400 during marking, ensuring that the marking information is accurate and reliable.

[0063] In this embodiment, in order to be able to handle multiple workpieces 400 at the same time, the marking device 600 is equipped with multiple marking heads 620, each of which corresponds to a mark area. The control device 700 determines whether each workpiece 400 is qualified according to the detection results of the testing device 500, and then drives the corresponding marking head to perform the marking operation. Multiple marking heads can work in parallel, greatly improving the marking efficiency.

[0064] In an embodiment, the mark plate 210 is located on one side of the carrier 200, and the conveying device 300 is configured to convey the carrier 200 through the marking device 600 and the marks through the marking heads 620.

[0067] In the embodiment, the ink pad storage mechanism 650 further comprises a horizontal moving mechanism, which is used to extend the ink pad storage mechanism 650 below the marking head. The ink pad storage mechanism 650 can be set by the control device 700 to replenish the ink pad of the marking head 620 at a certain frequency, which can be a time frequency (how long to replenish once) or an action frequency (marking head action three times to replenish once). The ink pad replenishment can also be monitored in real time by setting a visual sensor on the ink pad storage mechanism 650 to monitor the state of the ink pad of the marking head 620, and dynamically replenish the ink pad. During the process of replenishing the ink pad, the ink pad storage mechanism 650 needs to be moved to the position directly below the marking head 620 by the moving mechanism, and then the marking head 620 can extend into the ink pad storage mechanism 650 to replenish the ink pad. After replenishing, the ink pad storage mechanism 650 returns to the original position, which does not affect the normal work of the marking head 620.

[0068] In an embodiment, the driving mechanism 630 is a pneumatic cylinder, the cylinder body of the pneumatic cylinder is connected with the support 610, and the piston head of the pneumatic cylinder is provided with the marking head 620.
