[0023] Reference to an "embodiment" in this document means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combinable with other embodiments.

[0024] Please refer to Figure 1 , Figure 1 is a perspective structural schematic diagram of an embodiment of the printing device 10 provided by the application. The printing device 10 in the embodiment includes a printing mechanism 20, a carbon tape mechanism 30, and an adsorption mechanism 40.

[0025] Please refer to Figure 2 , Figure 3 and Figure 4 , Figure 2 is a perspective structural schematic diagram of the printing device 10 in Figure 1 , Figure 3 is a perspective structural schematic diagram of the print head assembly 22 in Figure 2 , Figure 4 is a cross-sectional schematic diagram of the print head assembly 22 in Figure 3 , The printing mechanism 20 includes a printing support 21 and a print head assembly 22, and the print head assembly 22 is installed on the printing support 21.

[0026] The print head assembly 22 includes a connecting seat 221 and a print head 222, the connecting seat 221 is connected with the printing support 21, and the print head 222 is used for printing the identification code information on the carbon tape 110 on the slide 120.

[0027] Further, the print head 222 is rotationally connected with the connecting seat 221, so as to adjust the angle of the print head 222 relative to the slide 120 in the process of printing according to the slide 120. In the embodiment, the print head 222 is rotationally connected with the connecting seat 221 through a rotating shaft 222a.

[0028] Specifically, in actual application, the slide 120 and the bottom end P of the print head 222 need to be in parallel, but in actual installation, errors may occur, causing the bottom end P of the print head 222 not to be in parallel with the slide 120, thereby causing printing failure. In the embodiment, in the printing process in which the print head 222 presses the carbon tape 110 on the slide 120, the print head 222 can rotate relative to the connecting seat 221, thereby adjusting the angle of the print head 222 relative to the slide 120, so that the bottom end of the print head 222 is in parallel with the slide 120, thereby ensuring the success of printing. For example, the slide 120 is generally horizontally placed. If in actual installation, the height of the left side of the bottom end P of the print head 222 in the vertical direction Z is lower than that of the right side of the bottom end P, then as described above, the print head 222 rotates relative to the connecting seat 221, so that the left side of the bottom end P rotates in the direction Z1, and the right side of the bottom end P rotates in the direction Z2, thereby making the bottom end of the print head 222 in parallel with the slide 120.

[0029] The elastic adjusting member 223 is arranged between the print head 222 and the connecting seat 221, and abuts against the print head 222 and the connecting seat 221, thereby improving the stability of the print head 222 in the adjusting process.

[0030] Further referring to Figure 3 The connecting seat 221 and the print support 21 are slidingly connected. In the embodiment, the print support 21 is provided with a guide rail 211, and the connecting seat 221 is arranged on the guide rail 211, so as to be slidingly connected with the print support 21 through the guide rail 211, thereby adjusting the position of the print head 222 according to the position of the slide 120, that is, adjusting the height of the print head 222 in the vertical direction Z.

[0031] Further, the first elastic pressing member 212 is arranged between the connecting seat 221 and the print support 21, and abuts against the connecting seat 221 and the print support 21, so as to provide the print head 222 with an elastic pressing force in the process of adjusting the position of the print head 222 according to the position of the slide 120, so that the print head 222 can press the carbon tape 110 on the slide 120, thereby completing printing.

[0032] Further, the printhead assembly 22 further comprises a detecting element 223 for detecting the breakage of the carbon ribbon 110. In the embodiment, the detecting element 223 is mounted on the connecting seat 221. In practical application, if the carbon ribbon 110 is broken while the printing device 10 is still in the working state of printing, the printhead 222 will be damaged. Therefore, in the embodiment, the detecting element 223 is used to detect the breakage of the carbon ribbon 110. When the carbon ribbon 110 is broken, the detecting element 223 generates a detecting signal that the carbon ribbon is broken. At this time, the printing device can stop working to avoid damaging the printhead 222.

[0033] Referring to Figure 2 , Figure 5 and Figure 6 , Figure 5 is Figure 2 a perspective exploded structure schematic view of the carbon ribbon mechanism 30 in FIG. 1, Figure 6 is Figure 5 a perspective structure schematic view of the second elastic pressing piece 33 in FIG. 2, the carbon ribbon mechanism 30 is used for loading the carbon ribbon 110. The carbon ribbon mechanism 30 comprises a carbon ribbon support 31, a carbon ribbon wheel 32 and a second elastic pressing piece 33. The carbon ribbon wheel 32 is used for loading the carbon ribbon 110 and is borne on the carbon ribbon support 31. The second elastic pressing piece 33 is connected with the carbon ribbon support 31 and is elastically pressed on the carbon ribbon wheel 32. When it is needed to replace the carbon ribbon 110, only the elastic pressing force of the second elastic pressing piece 33 needs to be overcome to dismount the carbon ribbon wheel 32 from the carbon ribbon support 31, and the replacement of the carbon ribbon 110 is completed.

[0034] Specifically, the carbon ribbon support 31 is formed with a mounting space 301 and a guide groove 302 in communication with the mounting space 301. The carbon ribbon wheel 32 is provided with a guide protrusion 3211. The guide protrusion 3211 is used to load the carbon ribbon wheel 32 into the mounting space 301 along the extension direction of the guide groove 302, i.e. the A direction shown in the figure. The second elastic pressing piece 33 is elastically pressed on the guide protrusion 3211, so that the carbon ribbon wheel 32 is pressed in the mounting space 301.

[0035] The carbon ribbon support 31 comprises a first sub-support 31a, a second sub-support 31b and a connecting piece 31c. The first sub-support 31a and the second sub-support 31b are oppositely arranged to form the mounting space 301. The connecting piece 31c connects the first sub-support 31a and the second sub-support 31b respectively.

[0036] The carbon belt wheel 32 comprises a feeding belt wheel 321 and a collecting belt wheel 322. The carbon belt 110 is arranged around the feeding belt wheel 321, and the leading end of the carbon belt 110 is connected with the collecting belt wheel 322. In actual use, the leading end of the carbon belt 110 can be connected with the collecting belt wheel 322 by means of adhesion. During printing, the collecting belt wheel 322 rotates relative to the carbon belt bracket 31, so as to gradually transfer the carbon belt 110 on the feeding belt wheel 321 to the collecting belt wheel 322.

[0037] In the embodiment, each of the feeding belt wheel 321 and the collecting belt wheel 322 is provided with a guide protrusion 3211 on each of the opposite sides. Correspondingly, the number of the guide grooves 302 is four, and the first sub-bracket 31a and the second sub-bracket 31b are respectively provided with two guide grooves 302.

[0038] Optionally, the extension direction A of the guide groove 302 is arranged to be inclined relative to the horizontal direction X. On one hand, the guide groove 302 can guide the carbon belt wheel 32 to be loaded into the mounting space 301. On the other hand, the carbon belt bracket 31 can bear the guide protrusion 3211 through the guide groove 302, and then bear the carbon belt wheel 32.

[0039] Further, the second elastic pressing piece 33 comprises a connecting portion 331 and an elastic pressing portion 332. The connecting portion 331 is connected with the carbon belt bracket 31, and the elastic pressing portion 332 is connected with the connecting portion 331 and elastically presses the guide protrusion 3211. When it is needed to dismount the carbon belt wheel 32 from the carbon belt bracket 31 to replace the carbon belt, only the elastic pressing portion 332 needs to be moved by external force to make the guide protrusion 3211 out of the pressing state, so that the carbon belt wheel 32 can be taken out from the mounting space 301.

[0040] In the embodiment, the connecting portion 331 is connected with the first sub-bracket 31a, and the number of the elastic pressing portion 332 is two. The two elastic pressing portions 332 are respectively connected with the connecting portion 331 on the opposite ends of the connecting portion 331. The two elastic pressing portions 332 are respectively used to elastically press the guide protrusion 3211 of the feeding belt wheel 321 and the guide protrusion 3211 of the collecting belt wheel 322.

[0041] Further, the second elastic pressing piece 33 is provided with a first positioning portion 33a, and the carbon belt wheel 32 is provided with a second positioning portion 32a. The first positioning portion 33a and the second positioning portion 32a are arranged in cooperation to position the installation position of the carbon belt wheel 32 on the carbon belt bracket 31. In the embodiment, the number of the first positioning portion 33a and the second positioning portion 32a is two respectively. The two first positioning portions 33a are respectively arranged on the two elastic pressing portions 332, and the two second positioning portions 32a are respectively arranged on the feeding belt wheel 321 and the collecting belt wheel 322.

[0042] Optionally, the first positioning part 33a is a positioning protrusion, and the second positioning part 32a is a positioning slot. It can be understood that, in other embodiments, the first positioning part 33a can also be a positioning slot, and the second positioning part 32a is a positioning protrusion.

[0043] Further referring to Figure 2 , the adsorption mechanism 40 is connected with one of the printing support 21 and the carbon tape mechanism 30, so as to adsorb the other one of the printing support 21 and the carbon tape mechanism 30, so that when the carbon tape 110 needs to be replaced, only the adsorption force of the adsorption mechanism 40 needs to be overcome, and then the carbon tape mechanism 30 can be detached from the printing support 21, and the replacement of the carbon tape 110 is completed.

[0044] It can be understood that, in the embodiment, when the carbon tape 110 needs to be replaced, the carbon tape mechanism 30 is first detached from the printing support 21 by overcoming the adsorption force of the adsorption mechanism 40, and then the carbon tape wheel 32 is detached from the carbon tape support 31 by overcoming the elastic pressing force of the second elastic pressing piece 33 as described above, and finally the replacement of the carbon tape 110 is completed.

[0045] Optionally, the adsorption mechanism 40 is a magnetic adsorption mechanism, such as a magnet, which is installed on the printing support 21 to magnetically adsorb the carbon tape support 31 of the carbon tape mechanism 30.

[0046] Optionally, the adsorption mechanism 40 can be one or more.

[0047] Further, the printing support 21 is provided with a first guide part 21a, and the carbon tape mechanism 30 is provided with a second guide part 30a, and the first guide part 21a and the second guide part 30a are inserted and connected, for example, the first guide part 21a is a guide column, and the second guide part 30a is a guide hole. During the installation of the carbon tape mechanism 30 on the printing support 21, the carbon tape mechanism 30 is moved along the extension direction of the guide column to approach the printing support 21, so that the guide column is inserted into the guide hole, and then the carbon tape mechanism 30 is adsorbed by the adsorption mechanism 40 to complete the installation of the carbon tape mechanism 30. When the carbon tape mechanism 30 needs to be detached, the adsorption force of the adsorption mechanism 40 is overcome, and the carbon tape mechanism 30 is pulled out of the guide column.

[0048] Through the insertion and connection of the first guide part 21a and the second guide part 30a, on the one hand, the installation and disassembly of the carbon tape mechanism 30 are guided, and on the other hand, the carbon tape mechanism 30 can also be carried in the direction of gravity.

[0049] Optionally, the number of the first guide part 21a and the second guide part 30a is multiple respectively.

[0050] In the embodiment, the guide hole is formed by the guide tube 30b installed on the printing support 31.

[0051] Further, the printing support 31 is provided with a handle 34, which is used to accept external force to install or dismount the carbon tape support 31 on the printing support 21.

[0052] As shown in Figure 1 FIG. 6, when the carbon tape mechanism 30 is installed on the printing support 21 as described above, the printhead 222 is deep into the installation space 301 of the carbon tape support 31, so that the printhead 222 can press the carbon tape 110 on the glass slide 120 during printing.

[0053] Further, the printing support 21 or the carbon tape mechanism 30 is provided with a detector 21b, which is used to detect the insertion position of the second guide part 30a relative to the first guide part 21a, so as to determine whether the carbon tape mechanism 30 is inserted in place, on the one hand, to avoid the situation that the printhead 222 cannot reach the preset position in the installation space 301 when the carbon tape mechanism 30 is not inserted in place, and on the other hand, to avoid the situation that the suction force of the suction mechanism 40 cannot suck the carbon tape mechanism 30 on the printing support 21.

[0054] For example, in the present embodiment, the detector 21b is an optical coupling, which is installed on the printing support 21, and the carbon tape mechanism 30 is provided with a sensing baffle 30c, which gradually approaches the optical coupling during the insertion of the second guide part 30a and the first guide part 21a, and if the sensing baffle 30c is inserted between the emitting end and the receiving end of the optical coupling, it means that the insertion is in place, otherwise it means that the insertion is not in place.

[0055] Please refer to Figure 7 and Figure 8 , Figure 7 is Figure 1 a cross-sectional view of the printing device 10 in FIG. 5, Figure 8 is Figure 7 an enlarged view of the M part in FIG. 5, the printing device 10 in the present embodiment further includes a driving mechanism 50, which is used to drive the carbon tape wheel 32 to rotate relative to the carbon tape support 31.

[0056] Specifically, the carbon tape wheel 32 is provided with a first adjusting part 3212, the driving mechanism 50 includes a driving unit 51 and an adjusting unit 52, the driving unit 51 is connected with the adjusting unit 52 to drive the adjusting unit 52 to rotate, the adjusting unit 52 is provided with a second adjusting part 52a, the first adjusting part 3212 and the second adjusting part 52a are used to cooperate with each other to make the carbon tape wheel 32 and / or the adjusting unit 52 rotate to the state that the first adjusting part 3212 and the second adjusting part 52a are engaged, so that when the driving unit 51 drives the adjusting unit 52 to rotate, the carbon tape wheel 32 is driven to rotate, avoiding the situation that the first adjusting part 3212 and the second adjusting part 52a cannot be engaged during installation, resulting in the carbon tape wheel 32 cannot rotate.

[0057] Wherein, the first adjusting part 3212 is arranged on the take-up roller 322, that is, in the embodiment, the driving unit 51 only needs to drive the take-up roller 322 to rotate through the adjusting unit 52, and then the carbon tape 110 is transmitted to the feed roller 321 to drive the feed roller 321, and then the carbon tape 110 on the feed roller 321 is transferred to the take-up roller 322, and the driving unit 51 does not need to directly drive the feed roller 321 to rotate, and correspondingly, the feed roller 321 does not need to perform the adjusting process of the first adjusting part 3212 and the second adjusting part 52a cooperating with each other, so that the structure of the whole device is simplified, and of course, in other embodiments, the feed roller 321 can also perform the adjusting process of the first adjusting part 3212 and the second adjusting part 52a cooperating with each other, which is not limited.

[0058] Wherein, the driving unit 51 includes a motor 511, a driving wheel 512, a driven wheel 513 and a transmission belt 514, the driving wheel 512 is connected with the output shaft of the motor 511, the transmission belt 514 is arranged around the driving wheel 512 and the driven wheel 513, and the adjusting unit 52 is connected with the driven wheel 513, so that the motor 511 drives the adjusting unit 52 to rotate through the driving wheel 512, the transmission belt 514 and the driven wheel 513, and then drives the take-up roller 322 to rotate.

[0059] Further, the detection element 223 described above is used to detect the breaking of the carbon tape 110, in the embodiment, the leading end of the carbon tape 110 is led out from the feed roller 321 and arranged around the carbon tape bracket 31, and then connected with the take-up roller 322, and since the printhead assembly 22 is deeply installed into the installation space 301 after being installed on the carbon tape bracket 31, the detection element 223 is arranged on the connecting seat 221 in the installation space 301, and detects whether the carbon tape 110 between the feed roller 321 and the take-up roller 322 is broken, and the specific detection method can be optical coupling detection, and the receiving end and the emitting end of the optical coupling are respectively located on both sides of the carbon tape, if the carbon tape is broken, the receiving end of the optical coupling can receive the optical coupling signal emitted by the emitting end, otherwise, it cannot be received, and of course, in other embodiments, the detection method can also be used for detection, which is not limited.

[0060] For reference Figure 9 , Figure 10 and Figure 11 , Figure 9 is Figure 8 a perspective view of the adjusting unit 52 in the embodiment, Figure 10 is Figure 9 a disengaged state diagram of the first adjusting part 3212 and the second adjusting part 52a in the embodiment, Figure 11 is Figure 9A schematic diagram of the engagement state of the first adjustment part 3212 and the second adjustment part 52a is shown. The first adjustment part 3212 is provided with a first inclined guide surface 321a, and the second adjustment part 52a is provided with a second inclined guide surface 52b. Under the guidance of the first inclined guide surface 321a and the second inclined guide surface 52b, the carbon belt pulley 32 and / or the adjustment unit 52 rotate until the first adjustment part 321a and the second adjustment part 52a are engaged.

[0061] For ease of explanation, in this embodiment, the first adjusting part 3212 is taken as an adjusting protrusion and the second adjusting part 52a as an adjusting groove, and the related descriptions below will also use this example. During installation, if... Figure 10 As shown, the adjusting protrusion 3212 and the adjusting groove 52a are misaligned and misaligned, that is, the center line T1 of the adjusting protrusion 3212 and the center line T2 of the adjusting groove 52a do not coincide. In this case, the adjusting protrusion 3212 cannot be inserted into the adjusting groove 52a upward in direction B1, or the adjusting groove 52a cannot be inserted into the adjusting protrusion 3212 in direction B2, which makes it impossible for the two to engage. However, in this embodiment, by setting the first inclined guide surface 321a and the second inclined guide surface 52b, the carbon belt pulley 32 and / or the adjusting unit 52 rotate, thereby aligning the adjusting protrusion 3212 and the adjusting groove 52a, that is, the center line T1 and the center line T2 coincide. At this time, the adjusting protrusion 3212 can be inserted into the adjusting groove 52a, so that the two can engage.

[0062] Optionally, there are two first inclined guide surfaces 321a and two second inclined guide surfaces 52b. The two first inclined guide surfaces 321a are arranged in a cross direction and along the rotation direction of the carbon belt pulley 32. The two second inclined guide surfaces 52b are arranged in a cross direction and along the rotation direction of the adjustment unit 52. This arrangement allows the adjustment process to be achieved by the cooperation of the corresponding first inclined guide surfaces 321a and second inclined guide surfaces 52b when the first adjustment part 3212 and the second adjustment part 52b are misaligned at different positions.

[0063] Optionally, there may be multiple first adjustment parts 3212 and multiple second adjustment parts 52a. The multiple first adjustment parts 3212 are arranged in an array along the rotation direction of the carbon belt pulley 32, and the multiple second adjustment parts 52a are arranged in an array along the rotation direction of the adjustment unit 52. For example, in this embodiment, there are four first adjustment parts 3212 and four second adjustment parts 52a.

[0064] Further, the adjusting unit 52 comprises a first connecting piece 521 connected with the driving unit 51, and an adjusting piece 522, the second adjusting part 52a is arranged on the adjusting piece 522, the adjusting piece 522 is in sliding connection with the first connecting piece 521, and an elastic piece 523 is arranged between the first connecting piece 521 and the adjusting piece 522, the elastic piece 523 abuts against the first connecting piece 521 and the adjusting piece 522 respectively, so that when the carbon wheel 32 and / or the adjusting piece 522 rotates under the guidance of the first inclined guide surface 321a and the second inclined guide surface 52b, the adjusting piece 522 moves towards the carbon wheel 32 under the elastic force of the elastic piece 523, and then the first adjusting part 3212 and the second adjusting part 52a are in the clamping state.

[0065] Specifically, when the adjusting protrusions of the first adjusting part 3212 and the adjusting grooves of the second adjusting part 52a are in the misaligned state as shown in Figure 10 , they are still apart by a distance H in the B direction, therefore, in order to realize the clamping state of the first adjusting part 3212 and the second adjusting part 52a as shown in Figure 11 , the adjusting piece 522 needs to move towards the carbon wheel 32 in the B2 direction while the carbon wheel 32 and / or the adjusting piece 522 rotates under the guidance of the first inclined guide surface 321a and the second inclined guide surface 52b, so that the adjusting protrusions are inserted into the adjusting grooves, and the elastic force generated by the abutment of the first connecting piece 521 and the adjusting piece 522 is used to make the adjusting piece 522 move towards the carbon wheel 32 under the elastic force.

[0066] The first connecting piece 521 is provided with a guide groove 5211, and the adjusting unit 52 further comprises a second connecting piece 524 connected with the adjusting piece 522 and arranged in the guide groove 5211, so that the adjusting piece 522 slides along the extension direction of the guide groove 5211 under the elastic force of the elastic piece 523, and the guide groove 5211 provides a guide for the direction of the adjusting piece 522, it can be understood that the extension direction of the guide groove 5211 is the B direction in Figure 9 , that is, the axial direction of the rotation of the first connecting piece 521.

[0067] Further, the second connecting piece 524 is arranged in cooperation with the guide groove 5211 in the direction perpendicular to the extension direction B, so that the adjusting piece 522 is relatively fixed with the first connecting piece 521 in the direction perpendicular to the extension direction B, that is, the adjusting piece 522 is relatively fixed with the first connecting piece 521 in the circumferential direction of the rotation of the first connecting piece 521, so that when the driving unit 51 drives the first connecting piece 521 to rotate, the adjusting piece 522 rotates synchronously, and then drives the carbon wheel 32 to rotate.

[0068] Further, the driving mechanism 50 further comprises a detection unit 53, which is installed on at least one of the motor 511, the driving wheels 512 and 513, and the driven wheels, to detect the rotational displacement of the motor 511.

[0069] In a specific application scenario, the slide 120 generally comprises a printing area and a coating area, the coating area being used for coating samples, and the printing head prints the identification code information on the printing area, thus the placement position of the slide 120 needs to match the movement direction of the carbon ribbon 110, and thus the detection unit 53 is used to detect the rotational direction of at least one of the motor 511, the take-up wheel 322, and the feed wheel 321, so as to detect the movement direction of the carbon ribbon 110, thereby avoiding the problem that the movement direction of the carbon ribbon 110 does not match the placement position of the slide 120, resulting in printing failure.

[0070] In another specific application scenario, when the carbon ribbon 110 on the feed wheel 321 gradually moves to the take-up wheel 322, the diameter of the carbon ribbon 110 wound on the take-up wheel 322 gradually increases, but in order to ensure the smooth running of the carbon ribbon 110, it is necessary to ensure that the tangential velocity V1 of the carbon ribbon 110 wound on the feed wheel 321 is the same as the tangential velocity V2 of the carbon ribbon 110 wound on the take-up wheel 322, where V1=W1×R1, V2=W2×R2, W1 is the angular velocity of the feed wheel 321, R1 is the common radius of the feed wheel 321 and the carbon ribbon 110 wound on the feed wheel 321, W2 is the angular velocity of the take-up wheel 322, and R2 is the common radius of the take-up wheel 322 and the carbon ribbon 110 wound on the take-up wheel 322, thus the detection unit 53 is further used to detect the movement trajectories of the feed wheel 321 and the take-up wheel 322, to determine whether the movement trajectories of the feed wheel 321 and the take-up wheel 322 match the movement trajectory of the detection unit 53, thereby avoiding the situation that the motor is stuck when they do not match.

[0071] Optionally, the detection unit 53 is a code disc, and the number of the code discs is three, which are respectively installed on the motor 511, the take-up wheel 322, and the feed wheel 321.

[0073] Among them, after the printing device 10 prints the identification code information on the slide, the push piece device 61 coats the samples on the slide, and the dyeing device 62 dyes the samples on the slide.
