[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0040] In related technologies, when printing wire marking tubes using a printer, a printing component prints the wire marking tubes, and a cutting component cuts the printed wire marking tubes. Additionally, to improve printing quality, a conveying component is usually included to transport the wire marking tubes. However, because the wire marking tubes are continuously transported during the cutting process, the cutting position becomes inaccurate, resulting in poor cutting quality.

[0041] To address the aforementioned issues, this application provides a printer that, by staggering the movement times of the driving component that drives the conveying component and the driving component that drives the cutting component, enables the cutting action of the cutting component and the conveying action of the conveying component to occur asynchronously, i.e., no conveying occurs during cutting, thereby improving the accuracy of the cutting position and enhancing the cutting effect.

[0042] See Figures 1 to 3 The printer 1 provided in one embodiment of this application includes a mounting plate 10, a conveying component 20, a cutting component 30, a first driving component 40, and a second driving component 50. The conveying component 20, the cutting component 30, the first driving component 40, and the second driving component 50 are all disposed on the mounting plate 10.

[0043] The shape of the mounting plate 10 is not limited. For example, according to spatial layout requirements, the mounting plate 10 is generally rectangular, and the four sides of the rectangular mounting plate 10 are respectively formed with recesses to avoid other components and protrusions for mounting and fixing. The central area of ​​the rectangular mounting plate 10 is provided with multiple mounting holes of the same or different shapes and sizes to facilitate the mounting and fixing of various components on the mounting plate 10.

[0044] The conveying component 20 provides a conveying path through a single conveying structure or a combination of conveying structures. The first driving component 40 is connected to the conveying component 20 and drives the conveying component 20 to move, so that the conveying component 20 can convey the printable part 2 along the conveying path.

[0045] The cutting assembly 30 generates a cutting path through a cutting element, such as a cutting blade. The second drive assembly 50 is connected to the cutting assembly 30 and drives the cutting assembly 30 to move, so that the cutting assembly 30 can cut the printable 2 that passes through the cutting path.

[0046] In related technologies, since the conveying component 20 continuously conveys the workpiece 2 to be printed, when the cutting component 30 performs the cutting action, the preset cutting part of the workpiece 2 to be printed has already left the cutting position of the cutting component 30, that is, the cutting position is inaccurate, resulting in poor cutting effect.

[0047] In this embodiment, the movement times of the first driving component 40 and the second driving component 50 are staggered, so that the cutting action of the cutting component 30 and the conveying action of the conveying component 20 are performed asynchronously, that is, no conveying occurs during cutting, thereby improving the accuracy of the cutting position and improving the cutting effect.

[0048] The staggered movement times of the first drive component 40 and the second drive component 50 can be achieved through a control circuit, which separately controls the first drive component 40 and the second drive component 50. The specific circuit structure of the control circuit is described in relevant technical documents and will not be elaborated here.

[0049] Optionally, the printer 1 also includes a housing with a transport channel for transporting the printable 2 to guide the transport direction of the printable 2.

[0050] Combination Figures 1 to 4 Optionally, the printer 1 also includes a printing assembly, which includes a print head 70 and a ribbon. During printing, the ribbon is located between the print head 70 and the workpiece 2 to be printed, and the print head 70 presses the ribbon against the surface of the workpiece 2 to achieve printing.

[0051] Optionally, the conveying assembly 20 includes several rollers. For example, the conveying assembly 20 includes a printing roller 21 and multiple conveying rollers 22. The printing roller 21 is positioned opposite and spaced apart from the printing assembly, such as the print head 70, forming a printing channel between the printing roller 21 and the print head 70 for the workpiece 2 to be printed and the ribbon to pass through. During printing, the printing roller 21 and the print head 70 cooperate to clamp the workpiece 2 to be printed and the ribbon, thereby printing the workpiece 2. The multiple conveying rollers 22 include a first conveying roller 22 and a second conveying roller 22 respectively disposed on both sides of the width direction of the conveying channel. By having the printing roller 21, the first conveying roller 22, and the second conveying roller 22 slide in contact with the workpiece 2 during the conveying process, the printed and cut workpiece 2 can be smoothly conveyed out of the conveying channel.

[0052] In some embodiments, the second drive component 50 is configured to start moving when the first drive component 40 stops moving. Thus, the movement times of the second drive component 50 and the first drive component 40 are staggered, with no time interval or a very small time interval between them. That is, after the printed part 2 is delivered to the position, the cutting component 30 quickly begins cutting, thereby improving printing and cutting efficiency while ensuring cutting quality.

[0053] In some embodiments, the first drive component 40 is configured to start moving when the second drive component 50 stops moving. Thus, the movement times of the second drive component 50 and the first drive component 40 are staggered, and there is no time interval or a very small time interval between them. That is, after completing one cut, the conveying component 20 quickly begins the next conveying operation, further improving printing and cutting efficiency.

[0054] In some embodiments, the first drive assembly 40 and the second drive assembly 50 are both located on the same side of the mounting plate 10 in the thickness direction. This allows for a reduction in the thickness of the printed part, thereby reducing its volume.

[0055] In some embodiments, the first drive assembly 40 and the second drive assembly 50 are both located on one side of the thickness direction of the mounting plate 10, while the conveying assembly 20 and the cutting assembly 30 are both located on the other side of the thickness direction of the mounting plate 10. Thus, while ensuring a small size for the printer 1, the various components of the printer 1 do not interfere with each other.

[0056] Combination Figure 2 , Figure 3 and Figure 5 In some embodiments, the first drive assembly 40 includes a first motor 41 and a first gear 42 connected to the motor shaft of the first motor 41. The mounting plate 10 is provided with a first mounting hole 11, and at least a portion of the first gear 42 extends into the first mounting hole 11 along the axial direction. For example, when the thickness of the first gear 42 along the axial direction is greater than the depth of the first mounting hole 11 along the axial direction, a portion of the first gear 42 extends into the first mounting hole 11; when the thickness of the first gear 42 along the axial direction is less than or equal to the depth of the first mounting hole 11 along the axial direction, the first gear 42 can be fully extended into the first mounting hole 11. Based on this, the thickness space occupied by the first gear 42 and the mounting plate 10 as a whole can be reduced, thereby reducing the volume of the printer 1.

[0057] Combination Figure 3 and Figure 4 For example, the conveying assembly 20 includes a conveying gear 23 and a conveying roller 22 connected to the conveying gear 23. The conveying gear 23 meshes with a first gear 42. The first gear 42 is driven to rotate by a first motor 41, thereby driving the conveying gear 23 to rotate, and in turn driving the conveying roller 22 to rotate.

[0058] For example, the conveying assembly 20 includes a conveying gear 23 and a conveying roller 22 connected to the conveying gear 23. The conveying gear 23 is connected to the first gear 42 through a plurality of sequentially meshing intermediate gears. The first gear 42 is driven to rotate by the first motor 41, thereby driving the conveying gear 23 to rotate, and in turn driving the conveying roller 22 to rotate.

[0059] In some embodiments, the diameter of the first mounting hole 11 is larger than the diameter of the addendum circle of the first gear 42. This prevents the first gear 42 from contacting the inner wall of the first mounting hole 11 during rotation, resulting in smoother rotation. It should be noted that when the diameter of the first mounting hole 11 is equal to the diameter of the addendum circle of the first gear 42, smooth rotation of the first gear 42 can also be ensured through lubrication or other means.

[0060] In some embodiments, the difference between the diameter of the first mounting hole 11 and the diameter of the tip circle of the first gear 42 is 1mm-5mm. For example, the difference between the diameter of the first mounting hole 11 and the diameter of the tip circle of the first gear 42 is 1.5mm, 2mm, or 3mm. Based on this, there is a sufficient gap between the first gear 42 and the inner wall of the first mounting hole 11, making it less likely that the vibration generated during the rotation of the first motor 41 will cause the first gear 42 to collide with the inner wall of the first mounting hole 11.

[0061] See Figure 2 , Figure 3 and Figure 5 In some embodiments, the second drive assembly 50 includes a second motor 51 and a second gear 52 connected to the motor shaft of the second motor 51. The mounting plate 10 is provided with a second mounting hole 12, and at least a portion of the second gear 52 extends into the second mounting hole 12 along the axial direction. For example, when the thickness of the second gear 52 along the axial direction is greater than the depth of the second mounting hole 12 along the axial direction, a portion of the second gear 52 extends into the second mounting hole 12; when the thickness of the second gear 52 along the axial direction is less than or equal to the depth of the second mounting hole 12 along the axial direction, the second gear 52 can be fully extended into the second mounting hole 12. Based on this, the thickness space occupied by the second gear 52 and the mounting plate 10 as a whole can be reduced, thereby reducing the volume of the printer 1.

[0062] For example, the cutting assembly 30 includes a cutting gear and a cutting blade connected to the cutting gear. The cutting gear meshes with a second gear 52. The second motor 51 drives the second gear 52 to rotate, thereby driving the cutting gear to rotate, which in turn drives the cutting blade to rotate.

[0063] For example, the cutting assembly 30 includes a cutting gear and a cutting blade connected to the transmission gear 23. The cutting gear and the second gear 52 are connected by a plurality of intermediate gears that mesh in sequence. The second motor 51 drives the second gear 52 to rotate, thereby driving the cutting gear to rotate, and in turn driving the cutting blade to rotate.

[0064] In addition, the cutting blade can also achieve linear motion through the cooperation of gears and racks.

[0065] In some embodiments, the diameter of the second mounting hole 12 is larger than the diameter of the tip circle of the second gear 52. Thus, the second gear 52 does not contact the inner wall of the second mounting hole 12 during rotation, making the rotation of the second gear 52 smoother.

[0066] In some embodiments, the difference between the diameter of the second mounting hole 12 and the diameter of the tip circle of the second gear 52 is 1mm-5mm. For example, the difference between the diameter of the second mounting hole 12 and the diameter of the tip circle of the second gear 52 is 1.5mm, 2mm, or 3mm. Based on this, there is sufficient air gap between the second gear 52 and the inner wall of the second mounting hole 12, making it less likely that the vibration generated during the rotation of the second motor 51 will cause the second gear 52 to collide with the inner wall of the second mounting hole 12.

[0067] Combination Figure 2 and Figure 6 In some embodiments, the printer 1 further includes a circuit board 60, to which both the first drive assembly 40 and the second drive assembly 50 are electrically connected. The circuit board 60 is used to drive the first drive assembly 40 and the second drive assembly 50 to move. Thus, connecting the first drive assembly 40 and the second drive assembly 50 through the same circuit board 60 simplifies the wiring and saves space.

[0068] In some embodiments, the circuit board 60, the first drive assembly 40, and the second drive assembly 50 are all located on the same side of the mounting plate 10 in the thickness direction. This results in shorter connection lines between the circuit board 60 and the first drive assembly 40 and the second drive assembly 50, and reduces the likelihood of interference with other components.

[0069] See Figure 7 In some embodiments, the mounting plate 10 has a first mounting area 13 and a second mounting area 14 spaced apart along a first direction X, the first direction X intersecting the thickness direction of the mounting plate 10. A first drive assembly 40 and a second drive assembly 50 are mounted in the first mounting area 13, and a circuit board 60 is mounted in the second mounting area 14. By partitioning the circuit board 60 with each drive assembly, wiring layout becomes more convenient.

[0070] In some embodiments, the distance between the first mounting area 13 and the second mounting area 14 is 5mm-100mm. For example, the distance between the first mounting area 13 and the second mounting area 14 is 5.5mm, 10mm, or 50mm. In this way, the distance between the first mounting area 13 and the second mounting area 14 is moderate, which ensures the compactness of the installation of each component and avoids interference between the components.

[0071] Combination Figure 2 and Figure 6In some embodiments, the printer 1 further includes a circuit board 60. A first drive assembly 40 has a first interface 411, and a second drive assembly 50 has a second interface 511. Both the first interface 411 and the second interface 511 are used for electrical connection with the circuit board 60. The first interface 411 is located on the side of the first drive assembly 40 closest to the circuit board 60, and the second interface 511 is located on the side of the second drive assembly 50 closest to the circuit board 60. Exemplarily, the first drive assembly 40 includes a first motor 41 with the first interface 411, and the second drive assembly 50 includes a second motor 51 with the second interface 511. Both the first interface 411 and the second interface 511 are used for electrical connection with the circuit board 60. The first interface 411 is located on the side of the first motor 41 closest to the circuit board 60, and the second interface 511 is located on the side of the second motor 51 closest to the circuit board 60. Thus, the connection lines between the first drive assembly 40 and the circuit board 60, and between the second drive assembly 50 and the circuit board 60, are shorter and have less bending.

[0072] See Figure 7 In some embodiments, circuit board 60 and first drive assembly 40 are arranged sequentially along a first direction X, and circuit board 60 and second drive assembly 50 are arranged sequentially along the first direction X, which intersects the thickness direction of mounting plate 10. First drive assembly 40 and second drive assembly 50 are arranged sequentially along a second direction Y, which intersects the thickness direction of mounting plate 10, and the angle between the second direction Y and the first direction X is an acute angle, such as 15°, 30°, or 60°. The circuit board 60, first drive assembly 40, and second drive assembly 50 are arranged closely on mounting plate 10, thereby reducing the size of printer 1.

[0073] Continue reading Figure 7 In some embodiments, the mounting plate 10 has a first mounting area 13 and a second mounting area 14 sequentially arranged along a first direction X. The first mounting area 13 includes a first sub-mounting area 131 and a wiring area 132 sequentially arranged along a third direction Z. Both the first direction X and the third direction Z intersect the thickness direction of the mounting plate 10, and the first direction X intersects the third direction Z. A first driving assembly 40 and a second driving assembly 50 are mounted in the first sub-mounting area 131, and a circuit board 60 is mounted in the second mounting area 14. The wiring area 132 is adjacent to both the first sub-mounting area 131 and the second mounting area 14, and both the first interface 411 and the second interface 511 face the wiring area 132. Thus, the bending degree of the connection lines between the first driving assembly 40 and the circuit board 60, and between the second driving assembly 50 and the circuit board 60, is relatively low.

[0074] Combination Figure 2 and Figure 6In some embodiments, the printer 1 further includes a circuit board 60, which has a third interface 61 and a fourth interface 62. The third interface 61 is used for electrical connection with the first drive assembly 40, and the fourth interface 62 is used for electrical connection with the second drive assembly 50. The third interface 61 is located on the side of the circuit board 60 facing the first drive assembly 40, and the fourth interface 62 is located on the side of the circuit board 60 facing the second drive assembly 50. Thus, the connection lines between the first drive assembly 40 and the circuit board 60, and between the second drive assembly 50 and the circuit board 60, are shorter.

[0075] In some embodiments, the orthographic projection of the circuit board 60 onto a reference plane has multiple connected edges, and the reference plane is perpendicular to the thickness direction of the circuit board 60. The orthographic projections of the third interface 61 and the fourth interface 62 onto the reference plane are located on the same edge. This simplifies the arrangement of the wiring on the mounting plate 10, thereby preventing wiring errors during the wiring process.
