[0051] The present invention provides a coding detection device 100.

[0052] A coding detection device 100 includes: a machine base 10; a first feeding component 20 disposed on the machine base 10, on which a label card A is placed; a second feeding component 30 disposed on the machine base 10, on which a label roll B is placed; a coding component 40 disposed on the machine base 10, the coding component 40 receiving the label card A or the coding component 40 pulling out a label strip from the label roll B, the coding component 40 coding the label card A or the label strip, and outputting the coded label card A or label strip.

[0053] Such as Figure 1As shown in the figure, in this embodiment, a first feeding component 20 and a second feeding component 30 can be arranged on the machine base 10. Among them, the first feeding component 20 is used to place multiple or stacked formed label cards A, while the second feeding component 30 is used to place a label roll B, and the label roll B is formed by winding label strips. In addition, a coding component 40 is arranged on the machine base 10. The coding component 40 can receive label cards A (single or multiple label cards A), or can receive label strips. During the operation of the first feeding component 20 and the second feeding component 30, only one of them can be used. For example, when coding a single-piece label, the first feeding component 20 is adopted, and the second feeding component 30 is not enabled. The label card A is placed on the first feeding component 20, and the coding component 40 receives the label card A from the first feeding component 20. The coding component 40 is on the transmission path of the label card A. For example, a belt or the like can be used for transmission. The label card A moves onto the coding component 40, and the coding component 40 performs a coding operation on the label card A and outputs a label strip at the same time. When coding a roll-type label, the second feeding component 30 is adopted, and the first feeding component 20 is not enabled. The roll-type label roll B is placed on the second feeding component 30, and the coding component 40 pulls out a label strip from the second feeding component 30. As the label strip runs on the transmission path of the label card A, the coding component 40 performs a coding operation on the label strip and outputs a label strip at the same time. Through the above structure, compared with the traditional coding printer, the coding detection device 100 of the present invention can be applied to a variety of different workpieces, with diverse functions. It can not only code roll-type labels but also single-piece labels.

[0054] Specifically, the first feeding component 20 includes: a first feeding bracket 21, the first feeding bracket 21 is arranged on the machine base 10, and the transmission path of the label card A passes through the first feeding bracket 21, and the label card A is placed in the first feeding bracket 21; a first baffle 22, the first baffle 22 is arranged on the first feeding bracket 21, and a gap is provided between the first baffle 22 and the bottom of the first feeding bracket 21. The first baffle 22 is used to block multiple stacked label cards A from passing through the gap and allow a single label card A to pass through the gap. As Figures 2 to 3As shown, in this embodiment, a first feeding bracket 21 is provided on the machine base 10, and the transmission path of the label card A passes through the first feeding bracket 21. For example, the first feeding bracket 21 can be arranged on the transportation path of the belt transmission mechanism, and the label card A is placed on the first feeding bracket 21. For example, a feeding area can be arranged on the first feeding bracket 21, the bottom of the feeding area is hollowed out, and the feeding area is located above the transmission path of the label card A. The label card A is automatically fed by gravity. Among them, the label card A closest to the transmission path of the label card A passes through the first feeding bracket 21 and enters the coding assembly 40. In addition, in order to prevent the phenomenon of multiple overlapping of the transmitted label cards A, a first baffle 22 can be arranged on the first feeding bracket 21, and a gap is provided between the first baffle 22 and the bottom of the first feeding bracket 21 for a single label card A to pass through the gap and be introduced into the coding assembly 40.

[0055] Specifically, the first feeding assembly 20 further includes: a second baffle 23, the second baffle 23 is arranged on the machine base 10, and the second baffle 23 is used to limit the label card A between the first baffle 22 and the second baffle 23. In this embodiment, a second baffle 23 can be added to the first feeding bracket 21 so that the label card A is limited on the first feeding bracket 21. Multiple stacked label cards A can be placed on the first feeding bracket 21 to improve the feeding efficiency.

[0056] Specifically, the first baffle 22 is an arc-shaped mechanism, and the concave surface of the first baffle 22 faces the coding assembly 40. As Figure 4 As shown, in this embodiment, in order to improve the smoothness of the label card A passing through the first feeding bracket 21, the first baffle 22 can be set as an arc-shaped structure, or the side of the first baffle 22 close to the transmission path of the label card A can be set as an arc-shaped structure, and the concave surface of the arc-shaped structure faces the coding assembly 40. When the label card A contacts the first baffle 22, it can pass through the first feeding bracket 21 along the arc-shaped mechanism through the above gap, improving the transmission efficiency of the label card A.

[0057] Specifically, the coding assembly 40 includes: a workbench 41, the workbench 41 is arranged on the machine base 10, the workbench 41 is located on the transmission path of the label card A and is downstream of the first feeding assembly 20 or the second feeding assembly 30; a coding scanning gun 43, the coding scanning gun 43 is arranged on the machine base 10; a coding near-field antenna 42, the coding near-field antenna 42 is arranged on the workbench 41, the coding scanning gun 43 and the coding near-field antenna 42 are in corresponding positions. After the coding scanning gun 43 identifies the identification code of the label card A or the label strip, the coding near-field antenna 42 codes the label card A or the label strip. As Figures 5 to 7As shown, in this embodiment, the workbench 41 of the coding component 40 can adopt a square structure and is arranged on the machine base 10. The workbench 41 is located downstream of the transmission path of the first feeding component 20 or the second feeding component 30 for the label card A, facilitating the reception of the label card A or the label strip from the first feeding component 20 or the second feeding component 30. A coding near-field antenna 42 is arranged on the workbench 41. The coding near-field antenna 42 can be embedded inside the workbench 41 to form a coding station on the workbench 41. Additionally, a coding scanning gun 43 is arranged on the machine base 10. The coding scanning gun 43 corresponds to the position of the coding near-field antenna 42 and is located above the workbench 41. When the label card A or the label strip is transmitted into the working range of the coding near-field antenna 42, that is, at the coding station, the coding scanning gun 43 identifies the identification code on the label card A or the label strip (the identification code of each label on each label card A or label strip is unique), and the coding near-field antenna 42 starts the coding operation on the label card A or the label strip, such as entering the EPC (Electronic Product Code).

[0058] Specifically, the coding detection device 100 further includes: a detection component, which is located on the transmission path of the label card A and downstream of the coding component 40. The detection component is used to detect whether the label card A after the coding operation by the coding near-field antenna 42 is qualified. In this embodiment, a coding detection component can be arranged downstream of the coding component 40 to detect whether the label card A after the coding operation by the coding near-field antenna 42 is qualified.

[0059] Specifically, the detection component includes: a detection scanning gun 45, which is arranged on the machine base 10; a detection near-field antenna 44, which is arranged on the workbench 41. The detection scanning gun 45 corresponds to the position of the detection near-field antenna 44. After the detection scanning gun 45 identifies the identification code of the label card A, the detection near-field antenna 44 is used to detect whether the label card A after the coding operation by the coding near-field antenna 42 is qualified. In this embodiment, the detection near-field antenna 44 and the detection scanning gun 45 are arranged on the workbench 41. The detection scanning gun 45 identifies the identification code of the label card A, and the detection near-field antenna 44 is used to detect whether the label card A after the coding operation by the coding near-field antenna 42 is qualified. When the label card A passes through the coding operation by the coding near-field antenna 42 and then is transported into the working range of the detection near-field antenna 44 (forming a reading code station on the workbench 41), the detection scanning gun 45 identifies the identification code of the label card A after the coding operation by the coding near-field antenna 42, and the detection near-field antenna 44 reads and obtains the entered EPC code, and pairs this EPC code with the pre-stored EPC code. If they are the same, it indicates a qualified label card A.

[0060] Specifically, the coding and detection device 100 further includes a rejection component 50. The rejection component 50 is disposed on the machine base 10. The rejection component 50 is located on the transmission path of the label card A and downstream of the detection component. The rejection component 50 is used to reject unqualified label cards A from the transmission path of the label card A. In this embodiment, the rejection component 50 is disposed on the machine base 10. The rejection component 50 is located downstream of the coding component 40 on the transmission path of the label card A. When the detection scanning gun 45 identifies the identification code of the label card A after the coding operation by the coding near-field antenna 42, the detection near-field antenna 44 obtains the input EPC code and pairs the EPC code with the pre-stored EPC code. If they are inconsistent, it indicates an unqualified label card A. At this time, the rejection component 50 rejects the unqualified label card A from the transmission path of the label card A.

[0061] As another embodiment, positioning sensors can be respectively disposed around the coding scanning gun 43 and the detection scanning gun 45 to determine the relative positions of the label card A or the label strip transmitted to the workbench 41, so as to improve the scanning accuracy of the coding scanning gun 43 and the detection scanning gun 45.

[0062] Specifically, the rejection component 50 includes: a rejection baffle 51, the rejection baffle 51 is rotatably connected to the machine base 10, and the rejection baffle 51 is located downstream of the detection near-field antenna 44 on the transmission path of the label card A; a waste collection member 52, the waste collection member 52 is disposed on the machine base 10, and the waste collection member 52 is used to collect the unqualified label cards A rejected by the rejection baffle 51. In this embodiment, the rejection baffle 51 of the rejection component 50 is rotatably connected to the machine base 10, and the relative rotation of the rejection baffle 51 can be driven by a motor. When the coding component 40 detects an unqualified label card A, the motor drives the rejection baffle 51 to rotate to block the unqualified label card A from continuing to be transported along the transmission path of the label card A, and a waste collection member 52 can be disposed on the machine base 10 to facilitate the unified collection of the unqualified label cards A rejected by the rejection baffle 51.

[0063] As another embodiment, an arc structure can be provided on the rejection baffle 51. When the coding component 40 detects an unqualified label card A, the rejection baffle 51 rotates, and the concave surface of its arc structure faces the coding component 40, so that the unqualified label cards A can gather in the waste collection member 52 along the concave surface of the arc structure. When the coding component 40 detects and outputs a qualified label card A, the rejection baffle 51 is stationary, and the qualified label card A passes through the rejection baffle 51 and continues to be transported to the next process.

For example, in the initial state, the lifting plate 62 is located at the top of the material receiving frame 61. As the qualified label cards A are collected, the lifting plate 62 slowly moves downward relying on the lifting guide rail, so that the qualified labels on the path of the label card A can be smoothly transported into the material receiving frame 61. When the material receiving frame 61 is full, the lifting plate 62 is located at the bottom of the material receiving frame 61, and the staff can take out the stacked qualified label cards A at one time, which is convenient for sorting.
