Abstract
Description
Technical Field
[0001] This utility model relates to the field of manufacturing equipment technology, and in particular to an automatic inkjet printing device for strip products. Background Technology
[0002] As is well known, some strip-shaped products need to be marked with inkjet printing during daily production. For example, FFC ribbon cables also need to be marked with inkjet printing on the materials during production. This is mainly to bind product information to the product itself and give the product a unique label.
[0003] Currently, most existing inkjet printing devices for strip products fix the inkjet printer head on a frame, and then the products below are transported in an orderly manner. Each time the product reaches the area that needs to be printed, the inkjet printer head performs the printing operation. However, in actual operation, because different products or different patterns need to be printed on the products, the printing position will change. Since the identification point is unique, the position of the inkjet printer head needs to be adjusted every time a different product or printing requirement is changed. This is fine when processing a single product, but if different products are frequently processed, a lot of time will be spent on assembling the inkjet printer head. In addition, position calibration is required every time it is installed, which is very inconvenient. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic inkjet printing device for strip products.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A material feeding space is formed between the two detector blocks. A right-angle prism is embedded in each detector block. One end face of the two right-angle prisms faces one point of the material feeding space, and the other end face of the right-angle prisms faces the camera.
[0013] Preferably, the main frame is also provided with two supplementary lights, the illumination direction of the supplementary lights is facing the material feeding space, and the beam of one of the supplementary lights shines into the material feeding space from above, while the beam of the other supplementary light shines into the material feeding space from below.

[0024] like Figures 1 to 5 As shown, this embodiment provides an automatic inkjet printing device for strip products, including a main frame 1 and a feeding mechanism 2, a guiding mechanism 3, an inkjet printing mechanism 4, and a receiving mechanism 5 mounted on the main frame 1. The feeding mechanism 2 is connected to the guiding mechanism 3, and the receiving mechanism 5 is located at the outlet of the guiding mechanism 3. The inkjet printing mechanism 4 includes a first linear module 41 driven by a servo motor and a gantry frame 42 spanning above the guiding mechanism 3. The first linear module 41 is placed on the side of the guiding mechanism 3. The bottom end of the gantry frame 42 is connected to a guide rail 43 arranged along the feeding direction of the guiding mechanism 3. The gantry frame 42 is fixedly connected to a movable seat on the first linear module 41. The 2 is equipped with a second linear module 44 driven by a servo motor. A base 45 is fixedly installed on the movable seat of the second linear module 44. A first rotary motor 46 is installed on the base 45 and a printing terminal 48 is installed through a bearing 47. A gear disk 49 is provided on the output shaft of the first rotary motor 46. A ring rack 401 is provided around the printing terminal 48. The gear disk 49 meshes with the ring rack 401. A limiting member 40 is provided on the side of the printing terminal 48 on the base 45 to limit the printing terminal 48 to rotate only 90°. The printing port of the printing terminal 48 is located directly above the material guiding mechanism 3. The printing terminal 48 is connected to the inkjet printer 101.
[0025] In this embodiment, the material is first sequentially fed through the feeding mechanism 2, guiding mechanism 3, and receiving mechanism 5. After feeding, the coding operation can be started. During coding, when the material reaches the coding mechanism 4, the first linear module 41 moves back and forth along the material feeding direction to reach the desired position for coding. Then, the second linear module 44 moves laterally left and right to bring the coding dock 48 to the final coding point, and coding can then be performed. When there is a coding direction requirement, the first rotary motor 46 rotates, and the meshing relationship between the gear disk 49 and the ring rack 401 rotates the coding dock 48 by 90°, causing the printed barcode to rotate 90°. These movable structures of the coding dock 48 allow the coding operation to move automatically to meet various coding position requirements, eliminating the need for repeated manual adjustments and effectively improving coding efficiency.
[0026] Furthermore, in order to allow the ink to dry quickly, a fan 402 is provided at the other end of the gantry 42 relative to the end where the inkjet terminal 48 is located. The airflow direction of the fan 402 is directly facing the material guiding mechanism 3. With this design, whenever the material is finished being printed, it is dried by the fan 402.
[0027] Furthermore, the rotation of the spray nozzle 48 is 90°. In order to accurately limit the rotation of the spray nozzle 48, a limiting component 40 is provided in this embodiment. The specific structure of the limiting component 40 includes a trigger block 403 fixedly installed on the spray nozzle 48 and two top contact switches 404 fixedly installed on the base 45. The included angle of the two top contact switches 404 is 90°. The trigger block 403 is always between the two top contact switches 404. In this way, whenever the spray nozzle 48 rotates, when it rotates to one end, the trigger block 403 will touch the top contact switch 404, thereby stopping the rotation and achieving the limiting.
[0028] Furthermore, in this embodiment, the feeding mechanism 2 specifically includes a material reel 21 storing material. The material reel 21 is rotatably mounted on the main body 1. The material reel 21 guides the material into the guiding mechanism 3 via a first roller group 22. The guiding mechanism 3 in this embodiment includes a guiding trough 31 horizontally arranged on the main body 1. One end of the guiding trough 31 is a feed inlet for receiving the material introduced by the feeding mechanism 2, and the other end of the guiding trough 31 is a discharge outlet. At least one driven roller 32 for receiving material is provided in the guiding trough 31. The gantry frame 42 spans the guiding trough 31, and the spray nozzle 48 is located above the guiding trough 31.
[0029] Furthermore, although the materials are taut during transport, to ensure the materials are fixed during inkjet printing and prevent them from shaking, support frames 33 are provided at both the inlet and outlet of the guide trough 31 in this embodiment. A second rotary motor 34 and a cylinder 35 are mounted on the support frame 33. An active roller shaft 36 is mounted on the output shaft of the second rotary motor 34. A pressure roller shaft 37 is connected to the push head of the cylinder 35. The pressure roller shaft 37 and the active roller shaft 36 are symmetrically arranged. When inkjet printing is required, both cylinders 35 operate, pressing the pressure roller shaft 37 against the active roller shaft 36 to create a clamping effect, thus clamping the materials and improving their stability. The second rotary motor 34 is used to assist in material transport, providing pushing force during long-distance material transport.
[0030] Furthermore, for precise coding location, since materials are generally marked with markers, such as a hole or a line with different colors, this marker point is used as a coordinate point to extend the coordinates to the location to be coded, thereby moving the inkjet nozzle 38 to the corresponding position for coding. To identify this marker, a camera 38 is specially installed on the side of the material guide chute 31. Two symmetrically arranged detection blocks 39 are installed at the inlet of the material guide chute 31, forming a material feeding space 30 between the two detection blocks 39. Each detection block 39 is embedded with... There are two right-angle prisms 301, with one end face of each prism 301 facing a point in the material feeding space 30, and the other end face of each prism 301 facing the camera 38. With this design, regardless of whether the marking point is on the front or bottom surface of the material, as long as the material passes through the feeding space, the two right-angle prisms 301 can reflect the material's two ends, allowing a single camera 38 to capture the image. The location of the marking is determined by whether the marking is captured. The specific calculation of the marking location is based on system calculation rules, such as the relationship between the specific location and the transmission speed S. 距 =V 速 *t 时 Meanwhile, the position of the detector block 39 is a constant coordinate value, the initial position of the spray dock 48 is also a constant coordinate value, the focal length of the camera 38 is a constant value, and the distance of the detected image to the side is converted to the horizontal distance by a ratio value, so as to obtain the X-axis distance and Y-axis distance that the spray dock needs to move.
[0031] Furthermore, to avoid poor lighting conditions that prevent the markings from being captured, the main frame 1 in this embodiment is also equipped with two supplementary lights 302. The illumination direction of the supplementary lights 302 is directly facing the material feeding space 30, and the beam of one of the supplementary lights 302 enters from above the material feeding space 30, while the beam of the other supplementary light enters from below the material feeding space 30.
[0032] Furthermore, in this embodiment, the specific structure of the receiving mechanism 5 includes a receiving reel 51 mounted on the main body 1 and rotatable by a motor. The receiving reel 51 receives material from the guide trough through the second roller group 52.
[0033] In addition, it should be noted that the material reel 21 and the take-up reel 51 are both conventional material reels on the market, which meet the requirements for disassembly and assembly and the setting for motor-driven rotation.
[0034] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
