Description

Technical Field

[0001] The present invention relates to the technical field of inkjet printers, and in particular to a positioning cover assembly and an inkjet device. Background Art

[0002] Existing inkjet equipment typically uses UV inkjet technology to print products. During the printing process, materials need to be transported to different workstations for different processes, including horizontal and vertical material transportation. During the vertical transportation process, the material is lifted by the inkjet equipment's lifting mechanism to abut against the positioning cover at the target height, positioning the material at the target height for inkjet printing, curing, and other operations.

[0003] Most of the cover plates in the prior art are of one-piece type. One-piece positioning cover plates have the following defects when in use: (1) The irradiation heat during UV curing can cause the positioning cover plate to deform significantly, resulting in the top surface of the material being unable to fit stably with the positioning cover plate, thereby affecting the vertical positioning accuracy of the material; (2) The material has a large drop during the rising process, and the material is prone to vertical deviation, thereby affecting the vertical positioning accuracy of the material. (3) When the top or bottom surface of the material is uneven, it will also cause the top surface of the material to be unable to fit stably with the positioning cover plate, thereby affecting the vertical positioning accuracy of the material. These defects all affect the quality of the finished product after the coding is completed. Summary of the Invention

[0004] The object of the present invention is to provide a positioning cover plate assembly and an inkjet device, which can ensure the position accuracy of materials in the horizontal and vertical directions and improve the quality of finished products.

[0036] See Figures 1 to 5, this embodiment provides a positioning cover plate assembly, which can ensure the positioning accuracy of the material in the horizontal and vertical directions and improve the quality of the finished product. The positioning cover plate assembly includes a connecting plate 1, a cover plate structure and a correction mechanism 3. Among them, the connecting plate 1 is erected at the target height, and a through groove 11 is provided on the connecting plate 1, and the through groove 11 is used to avoid the material. The cover plate structure includes a plurality of positioning cover plates 2, and the plurality of positioning cover plates 2 are arranged on the top surface of the connecting plate 1 along the circumferential intervals of the through groove 11. One end of the positioning cover plate 2 extends to the through groove 11, and the rising material can abut against the partial structure of the plurality of positioning cover plates 2 extending into the through groove 11. The correction mechanism 3 is provided on the side of the connecting plate 1 facing away from the positioning cover plate 2, and the correction mechanism 3 is used to straighten the material in the horizontal direction.

[0037] The positioning cover assembly provided in this embodiment is erected at the target height through the connecting plate 1. When transporting materials, the materials are lifted up to abut against the portion of the structure where the positioning cover plates 2 extend through the slots 11. At the same time, the deviation correction mechanism 3 is driven to straighten the materials, thereby accurately positioning the materials at the target height. Figure 3 , multiple positioning cover plates 2 are arranged at intervals along the circumference of the groove 11 so that the cover plate structure can form multiple points of contact with the top surface of the material. Compared with the one-piece cover plate, it has higher flexibility, so that the top surface of the material and the cover plate structure can be stably fitted, ensuring the position accuracy of the material in the vertical direction. That is, this embodiment ensures the position accuracy of the material in the vertical direction by adopting a split cover plate structure. At the same time, the split cover plate structure is easy to process and has higher processing accuracy than the one-piece positioning cover plate 2. The correction mechanism 3 can straighten the material and prevent the material from shifting in the horizontal direction, thereby ensuring the position accuracy of the material in the horizontal direction.

[0038] Optionally, see Figure 1 and Figure 2 , the correction mechanism 3 includes two in the first direction ( Figure 1 The first deflection correcting parts with adjustable spacing in the middle X direction) are located on both sides of the material, and the two first deflection correcting parts can abut against the two first side surfaces of the material in the first direction in a one-to-one correspondence. Specifically, in this embodiment, the positioning cover assembly is installed at the top of the bracket of the lifting mechanism of the inkjet device. The material is prone to deviation during the transmission process. By adjusting the spacing between the two first deflection correcting parts, the two first deflection correcting parts are respectively abutted against the two first side surfaces of the material in the first direction, so as to Figure 1 The material is straightened in the middle Y direction) to ensure the horizontal position accuracy of the material in the second direction, which is perpendicular to the first direction. Optionally, the connecting plate 1 is fastened to the bracket of the jacking mechanism by bolts.

[0039] Furthermore, the correcting mechanism 3 includes two second correcting portions with adjustable spacing in the second direction. The two second correcting portions are located on either side of the material, and are capable of abutting the two second side surfaces of the material in the second direction in a one-to-one correspondence. Similarly, by adjusting the spacing between the two second correcting portions, the two second correcting portions abut the two second side surfaces of the material in the second direction, thereby straightening the material in the second direction and ensuring the horizontal position accuracy of the material in the second direction.

[0040] Preferably, the first deflection-correcting portion includes a first movable bracket 31 and a first roller 32 disposed on the first movable bracket 31. The first movable bracket 31 is movably disposed on the connecting plate 1 along a first direction, and the first roller 32 is configured to roll in contact with the first side surface of the material. The spacing between the two first deflection-correcting portions can be adjusted by driving the two first movable brackets 31 toward or away from each other, making adjustment very convenient. As the material enters the lifting mechanism, the two first movable brackets 31 are driven toward each other, causing the first roller 32 to roll in contact with the two first side surfaces of the material in the first direction, thereby straightening the material in the first direction. The provision of the first roller 32 can reduce friction between the first deflection-correcting portion and the material while preventing the first deflection-correcting portion from scratching the material.

[0041] Preferably, a plurality of first rollers 32 are arranged at intervals along the second direction, and the second direction is perpendicular to the first direction. Such an arrangement can increase the contact area between the first deviation-correcting portion and the material, improve the straightening effect, and further ensure the position accuracy of the material.

[0042] Furthermore, the second deflection-correcting unit includes a second movable bracket 33 and a second roller 34 mounted on the second movable bracket 33. The second movable bracket 33 is movably mounted on the connecting plate 1 in the second direction. The second roller 34 is configured to roll against the second side surface of the material. With this arrangement, the spacing between the two second deflection-correcting units can be adjusted by driving the two second movable brackets 33 toward or away from each other. As the material rises, the two second movable brackets 33 are driven toward each other, causing the second roller 34 to roll against the two second side surfaces of the material in the second direction, thereby straightening the material in the second direction. The provision of the second roller 34 reduces friction between the second deflection-correcting unit and the material while preventing it from scratching the material. In this embodiment, multiple second rollers 34 are spaced apart along the height of the material. This arrangement increases the contact area between the second deflection-correcting unit and the material, improving the straightening effect and further ensuring the positioning accuracy of the material.

[0043] Optionally, the positioning cover assembly further includes two first drive members 4, each corresponding to the two first deflection-correcting portions. The first drive members 4 are disposed on the connecting plate 1 and have their output ends connected to the first movable bracket 31, thereby driving the movement of the first movable bracket 31. The two first drive members 4 can correspondingly drive the movement of the two first movable brackets 31, thereby conveniently adjusting the spacing between the two first deflection-correcting portions. Furthermore, both first drive members 4 are communicatively connected to the control system of the inkjet device to automatically control the movement of the first movable bracket 31 through the control system. Optionally, the first drive members 4 can be, but are not limited to, electric cylinders or pneumatic cylinders.

[0044] Optionally, the positioning cover assembly further includes two second drive members 5, which are arranged in a one-to-one correspondence with the two second deflection-correcting portions. Mounting brackets 13 are provided at opposite ends of the connecting plate 1. The second drive members 5 are disposed on the mounting brackets 13, and the output ends are connected to the second movable brackets 33, for driving the second movable brackets 33 to move. The two second drive members 5 can correspondingly drive the two second movable brackets 33 to move, thereby conveniently adjusting the spacing between the two second deflection-correcting portions. Furthermore, both second drive members 5 are communicatively connected to the control system of the inkjet device so that the movement of the second movable brackets 33 can be automatically controlled by the control system. Optionally, the second drive members 5 can be, but are not limited to, electric cylinders or pneumatic cylinders.

[0045] Furthermore, a first guide rail 12 is provided on the connecting plate 1 along the moving direction of the first movable bracket 31. A first slider 311 is provided on the first movable bracket 31. The first slider 311 is slidably connected to the first guide rail 12. The first guide rail 12 can provide guidance for the movement of the first movable bracket 31, ensuring the stability of the movement of the first movable bracket 31. The first guide rail 12 can also limit the movement of the first movable bracket 31 to prevent the first movable bracket 31 from detaching from the connecting plate 1. In this embodiment, refer to Figure 4 and Figure 5 A first guide groove (not shown in the figure) is provided on the first guide rail 12 along its extension direction. The first slider 311 is inserted into the first guide groove and slides with the first guide groove. This structural setting realizes the sliding connection between the first movable bracket 31 and the first guide rail 12.

[0046] Furthermore, a second guide rail is provided on the mounting frame 13 along the direction of movement of the second movable bracket 33. A second slider 331 is provided on the second movable bracket 33, and the second slider 331 is slidably connected to the second guide rail. The second guide rail provides guidance for the movement of the second movable bracket 33, ensuring its stability. The second guide rail also limits the travel of the second movable bracket 33, preventing it from detaching from the mounting frame 13. Preferably, a second guide groove 131 is provided along the second guide rail along its extension direction. The second slider 331 engages in the second guide groove 131 and slidably engages with the second guide groove 131. This structural arrangement achieves a sliding connection between the second movable bracket 33 and the second guide rail.

[0047] Optionally, the positioning cover plate 2 is detachably connected to the connecting plate 1 via fasteners. The fasteners can stably connect the positioning cover plate 2 to the connecting plate 1, while being easy to assemble and disassemble, convenient for maintenance and replacement, and facilitating individual adjustment of each positioning cover plate 2, providing high flexibility. Optionally, the fasteners are bolts.

[0048] Optionally, the positioning cover plate 2 is made of P20 stainless steel or SUS440C stainless steel. P20 stainless steel or SUS440C stainless steel can maintain its shape at high temperatures and is not easily deformed, thereby preventing the positioning cover plate 2 from deforming under the irradiation heat during UV curing and ensuring the structural stability of the positioning cover plate 2.

[0049] Optionally, see Figure 1 The positioning cover assembly also includes a detection element 6, which is arranged on the connecting plate 1 and is used to detect whether the material is in contact with the positioning cover 2. During the process of lifting the material, the detection element 6 can detect whether the material is in contact with the cover, thereby judging whether the material is lifted into place, so as to facilitate the inkjet device to perform subsequent operations such as inkjet and curing on the material. Furthermore, the detection element 6 is communicatively connected to the control system of the inkjet device. It can be understood that when installing the positioning cover 2, the horizontality of multiple positioning cover plates 2 can be detected by the detection element 6 to judge whether the multiple positioning cover plates 2 are installed in place, thereby ensuring the installation accuracy of multiple positioning cover plates 2. Optionally, the detection element 6 is a photoelectric sensor. In this embodiment, the detection element 6 is set at the four end points of the top surface of the connecting plate 1. The setting of the photoelectric sensor is a prior art and is not described in detail in this embodiment.

[0050] This embodiment also provides an inkjet device, comprising a lifting mechanism and the aforementioned positioning cover assembly, wherein the lifting mechanism is configured to drive the material upward until it abuts the positioning cover assembly. The inkjet device can ensure the horizontal and vertical positioning accuracy of the material, thereby improving the quality of the finished product.
