[0028] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of a first embodiment of a printing device provided by the present application, Figure 2 is Figure 1 a structural schematic diagram when a glass slide is placed in the printing area. As shown in Figure 1 and Figure 2 , the present application first provides a printing device, which comprises a printing assembly 10 and a carbon ribbon supply assembly 20.

[0029] The printing assembly 10 comprises a print head 110 and a print head driving mechanism 120, the print head driving mechanism 120 is connected with the print head 110; the printing assembly 10 is provided with a printing area 130, the printing area 130 is used for placing a glass slide 131 to be printed, the carbon ribbon supply assembly 20 is used for providing a carbon ribbon 210 for the printing area 130, and the print head driving mechanism 120 is used for driving the print head 110 to move along a first direction and press the carbon ribbon 210, so that the print head 110 prints the glass slide 131 under the carbon ribbon 210; wherein when the glass slide 131 is placed in the printing area 130, the width direction of the glass slide 131 is a second direction, and the second direction is parallel to the first direction.

[0030] Specifically, when the printhead driving mechanism 120 drives the printhead 110 to move in the first direction, the first direction can be understood as a horizontal direction, that is, the printhead 110 moves horizontally at least once in the printing process to print the information on the carbon ribbon 210 to the slide 131. The first direction is the printing direction of the printhead 110. The slide 131 is usually in a square structure, and the slide 131 includes a first side 131a and a second side 131b arranged vertically, the length of the first side 131a is greater than the length of the second side 131b, that is, the first side 131a can correspond to the long side of the slide 131, and the second side 131b can correspond to the short side of the slide 131. The direction parallel to the first side 131a can be the length direction of the slide 131, and the direction parallel to the second side 131b can be the width direction of the slide 131.

[0031] The printing area 130 is used to place the slide 131 to be printed, and the printhead driving mechanism 120 is used to drive the printhead 110 to move in the first direction in the printing area 130, and the printhead 110 is used to press the carbon ribbon 210 to the slide 131 to transfer the thermal release layer on the carbon ribbon 210 to the slide 131. Wherein, the slide 131 can further include a third side 131c and a fourth side 131d, the third side 131c is opposite to the second side 131b, and the fourth side 131d is opposite to the first side 131a. Since the existing slide 131 is usually in an elongated strip shape, and the printing length of the printhead 110 is usually less than or equal to the length of the third side 131c and the fourth side 131d, when the existing printing device feeds the slide 131 longitudinally, the printhead 110 will contact the third side 131c and the second side 131b of the slide 131 at the same time in the printing process, which causes the third side 131c and the second side 131b of the slide 131 to wear the printhead 110 at the same time, and the printhead 110 is seriously worn. In the present embodiment, the width direction of the slide 131 in the printing process is arranged to be parallel to the first direction, so that the printhead 110 of the present embodiment will only contact the second side 131b or the third side 131c of the slide 131 at most in the process of printing the slide 131, which can significantly reduce the wear of the printhead 110 and protect the printhead 110.

[0032] In the embodiment of the present application, the printing assembly 10 of the printing device comprises a print head 110 and a print head driving mechanism 120 connected with the print head 110; the printing assembly 10 is provided with a printing area 130 in which a slide 131 to be printed is placed, and a carbon ribbon supply assembly 20 is used to provide a carbon ribbon 210 for the printing area 130; the print head driving mechanism 120 is used to drive the print head 110 to move along a first direction and press the carbon ribbon 210, so that the print head 110 prints the slide 131 under the carbon ribbon 210; when the slide 131 is placed in the printing area 130, the width direction of the slide 131 is a second direction, and the second direction is parallel to the first direction. Therefore, the printing device of the embodiment adjusts the feeding direction of the slide 131 to be parallel to the printing direction of the print head 110, so that the print head 110 only contacts one side edge of the slide 131 at most during printing, which can reduce the damage of the edge of the slide 131 to the print head 110 and improve the service life of the print head 110.

[0033] In an embodiment, the print head 110 prints the slide 131 along the first direction, the print head 110 contacts one of the edges of the slide 131 extending along the width direction, and the print head 110 is located on one side of the other edge of the slide 131 extending along the width direction.

That is, in the printing device of the embodiment, the print head 110 contacts one of the second edge 131b and the third edge 131c when the print head 110 prints the slide 131 along the first direction, and the other of the second edge 131b and the third edge 131c is located on one side of the print head 110. In other possible embodiments, the print head 110 does not contact any of the second edge 131b and the third edge 131c, and the print head 110 is located in the area of the slide 131 between the second edge 131b and the fourth edge 131d.

[0036] Optionally, the carbon ribbon supply assembly 20 is configured to provide the carbon ribbon 210 for the printing area 130 and drive the carbon ribbon 210 to move along the first direction so that the carbon ribbon 210 is located above the slide 131, and the printhead driving mechanism 120 is configured to drive the printhead 110 to move along the third direction when the carbon ribbon 210 is static so that the printhead 110 presses the carbon ribbon 210, and the printhead driving mechanism 120 is further configured to drive the printhead 110 to move along the first direction so that the printhead 110 prints the slide 131 below the carbon ribbon 210; wherein the third direction is perpendicular to the first direction.

[0037] Specifically, before printing the slide 131, the unused carbon ribbon 210 needs to be driven to the slide 131 by the carbon ribbon supply assembly 20, and the relative static state between the carbon ribbon 210 and the slide 131 is maintained. The printhead driving mechanism 120 is configured to drive the printhead 110 to move along the third direction to press the carbon ribbon 210 on the slide 131, and the printhead driving mechanism 120 is further configured to drive the printhead 110 to move along the first direction so that the printhead 110 moves relative to the carbon ribbon 210 and transfers the transfer material on the carbon ribbon 210 to the slide 131 to print the sample information to the slide 131.

At this time, the left side of the printhead 110 will be pressed by the elastic force provided by the glass slide 131 during the pressing process, so that the first elastic member 1225 is pressed, and the first elastic member 1225 outputs an elastic force through the second elastic member 1225, so that the right side of the printhead 110 moves forward and approaches the glass slide 131 under the action of the elastic force, until the printhead 110 is completely attached to the glass slide 131.

[0056] In the present embodiment, through the interaction between the printhead 110 and the elastic members 1225 on both sides, the printhead 110 can adjust the angle of attachment to the glass slide 131 within a limited range, so as to reduce or avoid the problems of poor printing effect, influence on the supply of the carbon tape 210, and the like caused by the angle of the printhead 110 not being attached due to installation or other reasons, and improve the reliability and stability of the printing device.

[0057] The present embodiment also provides an automatic slide preparation and staining instrument, which comprises the printing device, the sample feeding assembly, the slide preparation assembly, and the staining assembly according to any of the above embodiments. The printing device is used for printing sample information on the glass slide 131 through the carbon tape 210. The sample feeding assembly is arranged on one side of the printing device, and is used for obtaining a sample to be tested. The slide preparation assembly is connected with the sample feeding assembly, and is used for adding the sample to be tested to the glass slide 131. The staining assembly is connected with the slide preparation assembly, and is used for adding a staining solution to the glass slide 131 including the sample to be tested for staining.

[0058] Specifically, the automatic slide preparation and staining instrument of the embodiment is used to realize automatic operations such as sample information printing, slide 131 loading and sample dropping, and staining of the sample to be tested. The printing device is used to print sample information on the slide 131 through the carbon tape 210. The sample information can be embodied in the form of an identification code, a two-dimensional code, a label, and the like, so that the corresponding test instrument can obtain the corresponding sample information by identifying the identification code, the two-dimensional code, the label, and the like when testing the prepared slide in the subsequent process. The sample inlet assembly is used to receive the sample to be tested for slide preparation. The sample to be tested can be a biological sample, for example, the sample to be tested can be a cell, blood, a tissue slice, urine, and the like. The staining assembly is used to add a staining solution to the slide 131 for staining. According to different staining methods (such as HE staining, immunohistochemical staining, fluorescent staining, and the like), the staining assembly can adjust the corresponding staining solution and the manner / program of adding the staining solution, which is not specifically limited herein.
