[0019] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0020] like Figure 1 As shown, a paper tape printing device provided in this embodiment includes a paper tape 1, a first reel 2, a second reel 3, a camera 4, a light source 5, a third motor 6, a movable slide rail 7, a workbench 8, a first motor 9, a second motor 10, a workbench 11 and a pressure rod 12.

[0021] The workbench 11 is the printer's workbench, equipped with a movable slide 7 extending in a first direction Y. The movable slide 7 is used to mount a work frame 8 on the workbench 11, enabling the work frame 8 and its components, such as paper tape, to be loaded or unloaded from the printing station. The third motor 6 is mounted on the workbench 11, with its power output connected to the work frame 8. A screw can be mounted on the motor shaft of the third motor 6. A connecting block, threadedly connected to the screw, is mounted on the bottom of the base plate 81 of the work frame 8. This screw is driven to rotate, causing the base plate 81 to move in the first direction Y.

[0022] The work frame 8 includes a base plate 81 and a frame body 82 disposed above the base plate 81. The base plate 81 is mounted on the movable slide rail 7. The frame body 82 has a certain height to allow the paper tape 1 to be output tangentially from the first reel 2 and input tangentially from the second reel 3.

[0023] The base plate 81 extends in the second direction X. A first reel 2 and a first motor 9 for driving the first reel 2 to release paper are disposed at one end of the base plate 81. A second reel 3 and a second motor 10 for driving the second reel 3 to retract paper are disposed at the other end of the base plate 81. The paper tape 1 is wound around the first reel 2 and the second reel 3 at both ends, respectively. The portion between the first reel 2 and the second reel 3 passes over the frame 82.

[0024] The front section of the paper tape 1 as it moves along the second direction X on the frame 82 is the printing zone A. The rear section of the paper tape 1 as it moves along the second direction X on the frame 82 is the detection zone B. A camera 4 and a light source 5 are mounted on the frame 82. The camera 4 is a 5D camera, and the light source 5 is a coaxial light source. The camera 4 and light source 5 are electrically connected to a control system. The first direction Y and the second direction X are perpendicular to each other when viewed from above and are located on the same plane. The detection zone B is located near the second reel 3.

[0025] A pressure rod 12 is provided on the frame body 82 of the working frame 8. The pressure rod 12 and the upper surface of the frame body 82 form a gap for the paper supply belt 1 to pass through. The pressure rod 12 is located in the lower section of the detection area B.

[0026] During operation, the third motor 6 is driven to push the working frame 8 and the parts installed thereon to move in the first direction Y to the working range of the printer's nozzle. At this time, the paper tape 1 is wound on the first reel 2. The end of the paper tape 1 is manually dragged to the pressure rod 12. The nozzle is started to print on the paper tape 1 at the printing area A. At this time, the end of the paper tape 1 is wound onto the second reel 3, and the paper tape 1 is displaced between the printing area A and the detection area B through the action of the first reel 2 and the second reel 3. During the displacement process, the camera 4 and the light source 5 are started to capture the printed pattern, and the captured electronic image is sent to the control system (industrial computer), and then the AI ​​software algorithm is used to determine whether the nozzle status meets the use requirements. When using, you only need to set the comparison standard of the printed image. The software comparison method is a prior art and will not be repeated here.
