Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

In addition, the terms "first", "second", are only for the purpose of description, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions, and moreover, the first feature is "above", "above" and "above" the second feature, which includes the first feature above and obliquely above the second feature, or only indicates that the first feature is higher than the second feature in horizontal height. The first feature is "below", "below" and "below" the second feature, which includes the first feature below and obliquely below the second feature, or only indicates that the first feature is lower than the second feature in horizontal height.

[0055] In the description of the present application, it is necessary to point out that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0056] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as a limitation of the present application.

[0057] As shown in Figures 1 to 13 The present application provides a code jetting machine for jetting codes for housings 100, the housings 100 correspond to the PCB boards one by one, each PCB board has a corresponding code A, the code jetting machine comprises a first image recognition mechanism, a first conveying mechanism 1, a code jetting mechanism 2, a second image recognition mechanism 3 and a transplanting mechanism 4. Among them, the first image recognition mechanism is used to obtain the code A; the first conveying mechanism 1 is used to transport the housings 100 along the first direction X; the code jetting mechanism 2 is in communication connection with the first image recognition mechanism, and can jet the code B corresponding to the code A on the housings 100; the second image recognition mechanism 3 is installed downstream of the code jetting mechanism 2, and the second image recognition mechanism 3 is used to obtain the code B from the housings 100; the transplanting mechanism 4 is installed downstream of the second image recognition mechanism 3, and the transplanting mechanism 4 is configured to move the unqualified products 102 out of the first conveying mechanism 1 when the second image recognition mechanism 3 determines that the housings 100 are unqualified products 102.

[0058] In this way, the code A carried by the PCB is acquired by the first image recognition mechanism, and the code B corresponding to the code A is acquired by the inkjet mechanism 2 according to the feedback signal of the first image recognition system. When the shell 100 under the transport of the first conveying mechanism 1 moves to the position below the inkjet mechanism 2, the first conveying mechanism 1 stops, the inkjet mechanism 2 sprays the code B on the shell 100, and then the first conveying mechanism 1 starts to transport the shell 100 to the second image recognition mechanism 3. The second image recognition mechanism 3 is used to detect the spraying quality of the inkjet mechanism 2. If the spraying quality meets the requirements, such as the clarity and integrity of the code B, the shell 100 is determined as a qualified product 101, and the first conveying mechanism 1 continues to transport the shell 100 to the subsequent work station. If the spraying quality does not meet the requirements, the shell 100 is determined as an unqualified product 102, and the transplanting mechanism 4 acquires the shell 100 and removes the shell 100 from the first conveying mechanism 1 during the transport of the shell 100. In this way, the shell 100 is marked, so that the shell 100 can be assembled with the corresponding PCB, and product traceability is facilitated. In the marking process, the inkjet mechanism can remove unqualified products, thereby improving the operation quality and efficiency.

[0059] For example, the PCBs include a first PCB and a second PCB. The first PCB and the second PCB pass through the first image recognition mechanism in sequence. When the first PCB passes through the first image recognition mechanism, the code A1 carried by the first PCB is acquired by the first image recognition mechanism, and the code B1 corresponding to the code A1 is acquired by the inkjet mechanism 2. When the shell 100 passes through the inkjet mechanism 2, the inkjet mechanism 2 sprays the code B1 on the shell 100. When the shell 100 passes through the second image recognition mechanism 3 and is determined as a qualified product 101, the shell 100 is the first shell 100, and the first shell 100 is a matched part of the first PCB. The first image recognition mechanism continues to recognize the code A2 of the second PCB, the inkjet mechanism 2 updates the spraying pattern to the code B2, and sprays the next passing shell 100. If the shell 100 is determined as an unqualified product 102 by the second image recognition mechanism 3, the inkjet mechanism 2 keeps the code B2 and continues to spray the next passing shell 100 until a qualified product 101 is generated.

[0060] It should be noted that when the second image recognition mechanism 3 detects, the inkjet mechanism 2 is in standby state and does not spray other shells 100. During this period, the first conveying mechanism 1 no longer provides new shells 100 to the inkjet mechanism 2.

[0061] It should be noted that the patterns of the code A and the code B can be the same, but the patterns of the code A1 and the code A2 are different.

[0062] It should be noted that the codes A carried by each PCB are different.

[0063] For example, when the second image recognition mechanism 3 detects that the code B on the shell 100 is blurred, has low definition, or is incomplete, the shell 100 is determined to be a defective product 102.

[0064] For example, the inkjet printer further comprises a mounting table 91 and a cover 92, the cover 92 is fixed with the mounting table 91 and forms a mounting space inside, the first conveying mechanism 1, the inkjet mechanism 2, the second image recognition mechanism 3, and the transplanting mechanism 4 are all installed in the mounting space.

[0065] Optionally, the first conveying mechanism 1 comprises two conveying assemblies, the two conveying assemblies are arranged at intervals in the second direction Y, and each conveying assembly comprises a first support frame 11, a transmission wheel 12, a transmission belt, and a first driver 14.

[0066] For example, the two conveying assemblies are respectively referred to as a first conveying assembly 1a and a second conveying assembly 1b, and the first conveying assembly 1a and the second conveying assembly 1b are arranged in mirror image in the second direction Y, that is, the first conveying assembly 1a and the second conveying assembly 1b are arranged at intervals in the second direction Y, and in the first direction X, the leading end of the first conveying assembly 1a is aligned with the leading end of the second conveying assembly 1b, and the trailing end of the first conveying assembly 1a is aligned with the trailing end of the second conveying assembly 1b, and the first conveying assembly 1a and the second conveying assembly 1b are used together to transport the shell 100.

[0067] Specifically, the conveying assembly comprises a first support frame 11, a transmission wheel 12, a first transmission belt 13, and a first driver 14. The first support frame 11 is installed on the mounting table 91, and the length direction of the first support frame 11 is parallel to the first direction X.

In this way, the transmission shaft 16 can be uniformly stressed in the axial direction of the transmission shaft 16, and synchronous driving force can be output to the first transmission belt 13A and the first transmission belt 13B, so as to avoid speed difference between the first transmission belt 13A and the first transmission belt 13B, and to avoid that the shell 100 cannot be smoothly conveyed.

Since the first conveying mechanism 1 can transport the shell 100 relative to the code spraying gun 23 along the first direction X, the relative movement between the shell 100 and the code spraying gun 23 can be realized along the first direction X, the second direction Y and the vertical direction Z, so that the code spraying gun 23 can spray code on a suitable area of the shell 100. The suitable area can be understood as a flat surface.
