Description

A multi-station inkjet printer Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to a multi-station inkjet printer. Background Technology

[0002] Using a voltage-driven device to apply a fixed pressure to the ink in the nozzle, it can be continuously ejected, or the ink can be ejected only when typing is required. It has a simple structure, low cost and relatively high reliability, but the ink droplet ejection speed is low due to the influence of jet inertia.

[0003] Traditional printers mostly use a single-station printing method, resulting in relatively low printing efficiency. Currently, to improve printing efficiency, multi-station printing is often employed, such as the inkjet printer disclosed in CN220332300U. This inkjet assembly includes a printhead oscillation structure, a printhead horizontal rotation structure, a printhead structure, and a printhead rotation structure. The printhead oscillation structure is rotatably connected to a mounting bracket, and the printhead horizontal rotation structure is rotatably connected to the printhead oscillation structure. However, increasing the number of stations leads to a corresponding increase in the printer's structure, size, and weight. Furthermore, the fixed multi-station design necessitates the transfer of items to be printed, requiring additional structural and functional modifications to the printer, and even manual intervention during printing, severely impacting printing efficiency and quality. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of inconvenience in using inkjet printers in the prior art, and to propose a multi-station inkjet printer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-station inkjet printer includes a body, a housing and a printing platform on the body, a guide beam movably disposed in the housing, a first drive mechanism on the housing for driving the guide beam to move vertically, an inkjet printing unit movably disposed on the guide beam, and a second drive mechanism on the guide beam for driving the inkjet printing unit to move left and right.

[0007] Preferably, a CCD camera located above the printing platform is fixedly mounted on the guide beam.

[0008] Preferably, the first driving mechanism includes guide rails integrally disposed on the left and right sides of the housing and used for slidingly mounting the guide beam. A first motor is fixedly installed in the housing, and a traction turntable is fixedly installed at the output end of the first motor. A limit groove is horizontally opened in the guide beam, and a driven block that is movably pulled by the traction turntable is slidably installed in the limit groove.

[0009] Preferably, the traction turntable is integrally connected with a traction bolt that is eccentrically positioned and movably fitted into the driven block.

[0010] Preferably, the second drive mechanism includes a second motor disposed in the guide beam and a ball screw driven to rotate by the second motor. A movable nut is provided on the ball screw, and a guide block that is slidably installed in the guide beam and fixedly connected to the movable nut is fixedly connected to the guide block.

[0011] Preferably, the second motor is fixedly installed in the guide beam, and the ball screw is rotatably installed in the guide beam.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model movably sets a guide beam on the housing of the machine body, and uses a guide slide rail to guide and limit the guide beam. The first motor drives the traction turntable to rotate, so that the driven block movably connected to the guide beam can make a smooth vertical lifting and lowering movement under the traction action of the traction turntable.

[0014] 2. This utility model utilizes a guide beam to movably set the inkjet printing unit. By setting a ball screw driven by a second motor to rotate, the moving nut and guide block drive the inkjet printing unit to perform reciprocating motion adjustment in the left and right direction.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Referring to Figures 1-6, a multi-station inkjet printer includes a body 1, on which a housing 2 and a printing platform 3 are provided. It should be noted that a 60*90cm printing platform 3 is provided for the workpiece to be printed, and it moves back and forth under the operation of the inkjet control system.

[0024] A guide beam 4 is movably installed in the housing 2. The guide beam 4 is made of aerospace-grade high-strength aluminum profile and industrial-grade linear guide rail. Under the drive of the first motor 62, it can achieve height adjustment within the range of 0-16cm. The housing 2 is provided with a first drive mechanism 6 for driving the guide beam 4 to move vertically. For details, please refer to Figures 2-5 in the instruction manual. The first drive mechanism 6 includes guide rails 61 integrally installed in the left and right sides of the housing 2 for slidingly mounting the guide beam 4. The first motor 62 is fixedly installed in the housing 2. A traction turntable 63 is fixedly installed at the output end of the first motor 62. A limit groove 64 is horizontally opened in the guide beam 4. A driven block 65, which is movably pulled by the traction turntable 63, is slidably installed in the limit groove 64. A traction bolt 66 is integrally connected to the traction turntable 63 and is eccentrically set and movably fitted in the driven block 65. It is worth noting that by driving the traction turntable 63 to rotate, the eccentrically set traction bolt 66 not only changes its horizontal position but also its height difference. Therefore, a driven block 65 that can cooperate with the traction bolt 66 to move obliquely is set on the guide beam 4.

[0025] An inkjet printing unit 5 is movably mounted on the guide beam 4. The inkjet printing unit 5 includes a high-strength aluminum machined part, a UV curing lamp, and an EPSON printhead. Under the control of the inkjet printing control system, it reciprocates along the guide beam 4, precisely spraying printing ink onto the workpiece. Simultaneously, the printing ink is cured under the UV curing lamp, completing the printing operation. A second drive mechanism 7 is provided on the guide beam 4 to drive the inkjet printing unit 5 to move left and right. Referring to Figures 3-6 in the instruction manual, the second drive mechanism 7 includes a second motor 71 located in the guide beam 4 and a ball screw 72 driven by the second motor 71. A movable nut 73 is fitted onto the ball screw 72, and a guide block 74, which is slidably installed in the guide beam 4 and fixedly connected to the inkjet printing unit 5, is fixedly connected to the movable nut 73. It should be noted that by controlling the movement of the movable nut 73 and the guide block 74, the inkjet printing unit 5 can move linearly back and forth in the left and right direction, facilitating the printing operation on the workpiece located on the printing platform 3. .

[0026] A CCD camera is fixedly installed on the guide beam 4 above the printing platform 3, and a CCD camera fixed below the guide beam 4. Under the control of the vision positioning system, the CCD camera scans the printed workpieces as the printing platform 3 moves back and forth and passes through the guide beam 4 in sequence. The algorithm calculation of the vision control software generates an image file containing multiple workpieces to be printed.

[0027] The second motor 71 is fixedly installed in the guide beam 4, and the ball screw 72 is rotatably installed in the guide beam 4.

[0028] It should be noted that the specific models and specifications of the first motor 62 and the second motor 71 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0029] The functional principle of this utility model can be explained through the following operation methods:

[0030] Placement of workpieces to be printed: Place multiple workpieces to be printed randomly on printing platform 3;

[0031] Scanning: The printing platform 3, on which multiple workpieces are placed, moves from front to back at a constant speed under software control. At the same time, the CCD camera located below the guide beam 4 starts scanning and automatically generates image files containing the outlines of all printed workpieces.

[0032] Visual positioning: In visual positioning software, select any workpiece and calibrate the position of the single image to be printed onto the workpiece with the workpiece.

[0033] Automatic positioning generation: Through a visual positioning algorithm, the software automatically matches and positions a single image with an image file containing the outlines of all printed workpieces to generate an image file;

[0034] Print output: Print the image file. During this process:

[0035] The first motor 62 drives the traction turntable 63 to rotate. The traction turntable 63 drives the driven block 65 to move along the limiting slide groove 64 through the traction bolt 66. Because the guide slide rail 61 limits the guide beam 4, the guide beam 4 can move vertically up and down.

[0036] The second motor 71 is turned on, causing the ball screw 72 to rotate. Because the guide block 74 limits the movement of the moving nut 73, the guide block 74 drives the inkjet printing unit 5 to move in a left-right direction.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
