Description

Technical Field

[0002] With the improvement of the automation level of medical detection, after collecting samples through carriers, more and more detection items are sent to detection instruments for detection, eliminating the need for doctors to manually prepare slides, conduct inspections, and then output results, which improves efficiency and reduces the labor intensity of doctors.

[0003] In order to ensure the accurate correspondence between the results of the detection instrument and the patient information, it is necessary to print the patient information on the carrier. There are mainly three ways to print patient information on the existing instruments: laser engraving, inkjet printing, and thermal transfer printing with a ribbon. Each of these methods has its own advantages and disadvantages. The advantage of laser engraving is that there is no consumable, but the printing time is long, the printing effect is not good, and harmful gases may be generated; inkjet printing requires special ink resistant to immersion in solutions such as ethanol and xylene, and needs to be cured after inkjetting, and it is also easy to fall off after curing; thermal transfer printing with a ribbon has a fast printing speed and good effect, so it has become a widely used printing method.

[0004] In the existing ribbon printing device, the ribbon is wound around the winding and unwinding structures for rotation, and in cooperation with the up and down movement of the print head, different segments of the ribbon are pressed onto the surface of the carrier for printing, so as to ensure the printing quality of continuous printing. However, when a roll of ribbon is completely used up, the disassembly and replacement are very troublesome. Especially, the printing ribbon needs to be wound around the guiding roller for guiding, and it is easy to get hands dirty during operation, or the ribbon may break. Summary of the Invention

[0052] As shown in the figure, an embodiment of the present invention provides a printing assembly, including: a printing mechanism 1, a carrier pushing mechanism 2, and a mounting structure 3, and a printing tape cassette is detachably mounted on the mounting structure 3;

[0053] The installation structure 3 includes a tape take-up wheel 31, a tape pay-out wheel 32, and a clamping and driving member 33 for clamping the printing tape and driving its movement. The tape take-up wheel 31 and the clamping and driving member 33 are respectively driven by a power mechanism, or both are driven by a tape driving mechanism 34;

[0054] The carrier pushing mechanism 2 is used to push the carrier;

[0055] The printing mechanism 1 is used to press the printing tape in the printing tape cassette onto the surface of the carrier for printing.

[0056] The present application provides a printing assembly, including: a printing mechanism 1, a carrier pushing mechanism 2, and an installation structure 3. The printing tape cassette is detachably installed on the installation structure 3; the installation structure 3 includes a tape take-up wheel 31, a tape pay-out wheel 32, and a clamping and driving member 33 for clamping the printing tape and driving its movement. The tape take-up wheel 31 and the clamping and driving member 33 are respectively driven by a power mechanism, or both are driven by a tape driving mechanism 34; the carrier pushing mechanism 2 is used to push the carrier; the printing mechanism 1 is used to press the printing tape in the printing tape cassette onto the surface of the carrier for printing.

[0057] In the printing assembly provided by the present application, the printing tape cassette is detachably arranged on the installation structure 3, and can cooperate with a modular printing tape cassette for printing. When it is necessary to replace the printing tape cassette, the box body can be directly removed and a new one can be replaced, without disassembling and assembling structures such as the tape take-up wheel 31, the tape pay-out wheel 32 or the clamping and driving member 33, which is simple and convenient. Moreover, the disassembly and assembly process of the printing tape cassette will not be hindered by the printing mechanism 1 and the carrier pushing mechanism 2, the operation difficulty is low, which is convenient for consumers to quickly replace the printing tape cassette and improve work efficiency. In addition, the provided clamping and driving member 33 and the tape take-up wheel 31 both provide power for the movement of the printing tape, and can also disperse the pressure.

[0058] Specifically, the working process of the printing assembly provided by the present application is as follows:

[0059] The printing tape cassette is detachably installed on the installation structure 3. The tape take-up wheel 31 and the tape pay-out wheel 32 are respectively inserted into the corresponding tape winding rings of the printing tape cassette and are clamped by conventional methods such as splines, so that the rotation of the tape take-up wheel 31 and the tape pay-out wheel 32 can drive the corresponding tape winding rings of the printing tape cassette to rotate; and, the clamping and driving member 33 also clamps the printing tape. After the printing tape cassette is installed in place, not only the components of the installation structure 3 are installed in place, but also the printing mechanism 1 is installed in place, and the printing tape in the printing tape cassette can be pressed onto the surface of the carrier for printing. Then, the carrier is placed on the carrier pushing mechanism 2 and is driven by it to reach the printing position, and the printing mechanism 1 presses down the printing tape to print corresponding information on its surface in cooperation with the movement of the carrier.

[0060] In this application, the tape take-up wheel 31 and the clamping driving member 33 are respectively driven by a power mechanism, or both are driven by the tape driving mechanism 34, and both can provide power. The tape pay-off wheel 32 can be driven by power or can be without power drive. When there is no power drive, the tape pay-off wheel 32 rotates under the force of the tape take-up wheel 31 and the clamping driving member 33 pulling the printing tape.

[0061] To prevent the tape pay-off wheel 32 from releasing too much printing tape, it is preferred to provide a damping member on the tape pay-off wheel 32.

[0062] The printing tape cassette adapted in this application is similar to the structure of a magnetic tape, and has two tape winding rings for cooperating with the tape take-up wheel 31 and the tape pay-off wheel 32. The printing tape is pre-wound on the winding rings. Before use, the printing tape is mainly wound around the tape pay-off wheel 32 and gradually transferred to the tape take-up wheel 31 during the use process. At the same time, the housing of the printing tape cassette also has a first notch for avoiding the print head 11 and a second notch for avoiding the clamping driving member 33; by providing a guide roller in the housing of the printing tape cassette, the printing tape can pass through appropriate positions of the first notch and the second notch, which is convenient for the print head 11 to press down on the printing tape or the clamping driving member 33 to clamp the printing tape.

[0063] Preferably, the first notch is provided on the bottom surface of the printing tape cassette, and the printing position passes through the bottom of the first notch and is basically flush with the bottom surface of the printing tape cassette to cooperate with the work of the print head 11 pressing down on the printing tape; while the second notch is located on the side wall of the printing tape cassette, and the printing tape passes through a place where the second notch is basically flush with the side wall to cooperate with the clamping and driving of the clamping driving member 33.

[0064] Preferably, the clamping driving member 33 includes a driving roller 331 and a clamping roller 332.

[0065] Preferably, the clamping driving member 33 includes a driving roller 331 and a clamping roller 332; the driving roller 331 rolls actively under the action of a driving force, and the clamping roller 332 presses the printing tape against the driving roller 331, so that the printing tape moves as the driving roller 331 rotates.

[0066] The second notch of the printing tape cassette is adapted to the driving roller 331, and the clamping roller 332 that is adapted or provided with an adjustment mechanism can clamp the printing tape outside the printing tape cassette, which is also convenient for the disassembly and assembly of the printing tape cassette. Preferably, the clamping driving member 33 further includes an adjustment mechanism, and the adjustment mechanism includes a rotating shaft 333, a rotating frame 334 and a locking member 335.

[0067] The rotating frame 334 is rotatably connected to the rotating shaft 333, and the clamping roller 332 is provided on the side of the rotating frame 334 close to the driving roller 331; the locking member 335 is used to lock the rotating frame 334 to the rotating shaft 333 or unlock it from the rotating shaft 333.

[0068] More preferably, the clamping driving member 33 further includes an adjusting mechanism, which includes a rotating shaft 333, a rotating frame 334 and a locking member 335. The rotating frame 334 is rotatably connected to the rotating shaft 333, and the clamping roller 332 is arranged on one side of the rotating frame 334 close to the driving roller 331. Then, the rotation of the rotating frame 334 can make the clamping roller 332 approach or move away from the driving roller 331; the locking member 335 is used to lock the rotating frame 334 to the rotating shaft 333 or unlock it from the rotating shaft 333, so as to adjust the tightness between the clamping roller 332 and the driving roller 331.

[0069] The locking member 335 is preferably a screw. The rotating frame 334 has a threaded hole matched with it. The screw passes through the threaded hole and abuts against the rotating shaft 333. Then, by rotating the screw, locking or loosening can be achieved. A rotating head convenient for operation can also be provided on the screw.

[0070] The adjusting mechanism can be installed at the position where the back plate 4 cooperates with the driving roller 331.

[0071] Preferably, the printing mechanism 1 includes a print head 11, a printing driving mechanism 12, a fixing frame 13 and a sliding frame 14.

[0072] The sliding frame 14 is slidably arranged on the fixing frame 13.

[0073] The printing driving mechanism 12 is installed on the fixing frame 13, the print head 11 is installed on the sliding frame 14, and the printing driving mechanism 12 is power-connected to the sliding frame 14 to drive the sliding frame 14 to slide relative to the fixing frame 13.

[0074] Preferably, the printing mechanism 1 includes a print head 11, a printing driving mechanism 12, a fixing frame 13 and a sliding frame 14. The sliding frame 14 is slidably arranged on the fixing frame 13. The printing driving mechanism 12 is installed on the fixing frame 13, the print head 11 is installed on the sliding frame 14, and the printing driving mechanism 12 is power-connected to the sliding frame 14 to drive the sliding frame 14 to slide relative to the fixing frame 13.

[0075] The fixing frame 13 is used for the installation and fixation of the entire printing mechanism 1, while the sliding frame 14 connects the printing driving mechanism 12 and the print head 11. The action of driving the print head 11 to descend or rise by the printing driving mechanism 12 is realized by driving the sliding frame 14 to slide relative to the fixing frame 13 by the printing driving mechanism 12. During this process, the print head fixedly connected to the sliding frame also slides up and down.

[0076] A guide rail slider mechanism can also be arranged between the sliding frame 14 and the fixing frame 13 to guide the sliding of the sliding frame 14.

[0077] Preferably, the fixing frame 13 is installed on the back plate 4, and the back plate 4 is also provided with an angle adjusting member 5 for adjusting the angle of the fixing frame 13.

[0078] When the fixing bracket 13 is installed on the back plate 4, it is preferably further provided with an angle adjusting member 5 to adjust the angle of the fixing bracket 13. During the installation process, the angle of the fixing bracket 13 is adjusted, thereby adjusting the angle of the print head 11 to ensure that the printing component can smoothly perform the printing work after installation.

[0079] Preferably, the back plate 4 has an adjustment hole, and the fixing member 41 passes through the adjustment hole and is connected to the fixing bracket 13;

[0080] The angle adjusting member 5 includes at least one movable adjusting push rod 51, which are respectively located on both sides of the adjusting fixing member 41 to adjust the position of the fixing member 41 in the adjustment hole.

[0081] Specifically, the back plate 4 is provided with an adjustment hole, the fixing member 41 passes through the adjustment hole and is connected to the fixing bracket 13, and the diameter of the adjustment hole is larger than the outer diameter of the part of the fixing member 41 located in the adjustment hole, having a certain adjustment space. The angle adjusting member 5 includes at least one movable adjusting push rod 51, which are respectively located on both sides of the adjusting fixing member 41 to adjust the position of the fixing member 41 in the adjustment hole.

[0082] The adjusting push rod 51 can be matched with a nut fixed to the back plate 4 through a thread. Rotating the adjusting push rod 51 can extend and abut against the fixing member 41. By adjusting the adjusting push rods 51 on both sides, the fixing member 41 can be fixed at the target position. The axial direction of the adjusting push rod 51 is consistent with the angle direction that usually needs to be adjusted when the print head 11 is installed. The adjustment hole is also preferably elongated, and is also consistent with the angle direction that usually needs to be adjusted when the print head 11 is installed.

[0083] When there is one adjusting push rod 51, by cooperating with a specific fixing member 41 (such as a nut of a specific model), the fixing member 41 is locked to the back plate 4, and the adjusting push rod 51 plays a role in preventing it from loosening and shifting, and can also achieve locking and fixing of the position. Preferably, two or more adjusting push rods 51 are provided to limit the position of the fixing member 41 from both sides or multiple directions.

[0084] The back plate 4 is also provided with a large hole for the print driving mechanism 12 to pass through.

[0085] Preferably, the print driving mechanism 12 includes a print power source 121, a cam 122 and a connecting rod 123,

[0086] The print power source 121 drives the cam 122 to rotate eccentrically;

[0087] One end of the connecting rod 123 is connected to the sliding bracket 14, and the other end is engaged with the cam 122;

[0088] An elastic member 15 is further provided between the sliding bracket 14 and the fixing bracket 13.

[0089] Preferably, the printing drive mechanism 12 includes a printing power source 121, a cam 122, and a connecting rod 123. The printing power source 121 drives the cam 122 to rotate eccentrically. One end of the connecting rod 123 is connected to the sliding carriage 14, and the other end is engaged with the cam 122. By driving the cam 122 to rotate eccentrically with the printing power source 121, the connecting rod 123 can be pressed down, and then the sliding carriage 14 descends accordingly. When the cam 122 rotates through a certain angle and no longer presses down the connecting rod 123, the sliding carriage 14 rises relative to the fixed frame 13 under the action of the elastic restoring force of the elastic member 15 to achieve reset.

[0090] The elastic member is preferably a spring, and a piston can also be provided in the spring to guide the spring.

[0091] Preferably, a bracket 6 for supporting the printing tape cassette is further provided below the mounting structure 3. The bracket 6 is slidable and has an open bottom; and / or,

The bracket 6 can be pulled out to place the printing tape cassette, and then the bracket 6 is pushed back so that the printing tape cassette is properly coordinated with the mounting structure 3, the printing mechanism 1, etc. The disassembly and assembly of the printing tape cassette are carried out in a direction perpendicular to the side surface of the printing tape cassette, avoiding the problem that the printing tape cassette needs to be tilted during disassembly and assembly and interfering with structures such as the take-up wheel 31. At the same time, the bottom of the bracket 6 is open, which does not affect the printing mechanism 1 and the printing tape from printing on the carrier on the lower carrier pushing mechanism 2.
