Description

Technical Field

[0001] This utility model relates to the field of polarizer technology, specifically to a polarizer coding mechanism. Background Technology

[0002] A polarizer is an optical element that converts natural light into polarized light. Its main function is to control the polarization direction of light, allowing light in a specific direction to pass through while absorbing or reflecting light in other directions. Polarizers play a crucial role in liquid crystal displays (LCDs). During the production process of polarizers, they need to be marked with inkjet printing, thus requiring an inkjet printing machine. This machine marks the polarizers with markings, facilitating product traceability and quality control, production process management, anti-counterfeiting and brand protection, process and subsequent processing assistance, and after-sales service and maintenance.

[0003] While traditional inkjet printing mechanisms have the ability to print on polarizers, they still have some shortcomings. For example, their positioning ability for polarizers is poor. Therefore, when printing on polarizers, the polarizers are prone to displacement or falling off, which will seriously affect the printing effect and efficiency. Therefore, a polarizer inkjet printing mechanism is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a polarizer inkjet printing mechanism with better positioning capability for polarizers. Therefore, when performing inkjet printing on polarizers, it is less likely to cause the polarizers to shift or fall off, thereby avoiding affecting the inkjet printing effect and efficiency of the polarizers, and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A reset groove and a movable groove are provided on one side of the snap-fit ​​groove. A moving groove is provided on the front side of the reset groove.

[0009] Preferably, a reset spring is fixedly connected to the side wall of the reset groove away from the snap-fit ​​groove. A reset support plate that is slidably connected to the reset groove is fixedly connected to the end of the reset spring near the snap-fit ​​groove. A positioning rod that penetrates the movable groove, extends into the snap-fit ​​groove, and corresponds to the position of the positioning slot and matches its specifications is fixedly connected to the end of the reset support plate near the snap-fit ​​groove.

[0010] Preferably, a connecting rod extending outward through the movable groove is fixedly connected to the reset support plate, and a movable handle is fixedly connected to the end of the connecting rod away from the reset support plate.

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] A polarizing film inkjet printing mechanism includes a substrate 1. A top plate 2 is fixedly connected to the top of the substrate 1 via fixed support rods at the four corners of the top. An inkjet printing station 3 is fixedly connected to the center of the top of the substrate 1. A negative pressure fan unit 4 is fixedly connected to the center of the bottom of the substrate 1. A first through groove 5 is opened at the center of the substrate 1. A second through groove 6 is opened at the center of the inkjet printing station 3. An adsorption plate 7 with matching specifications is provided in the second through groove 6. An installation assembly 8 is provided between the adsorption plate 7 and the inkjet printing station 3. An inkjet printing assembly 9 is provided on the top plate 2.

[0025] The mounting assembly 8 includes mounting plates 801 that are symmetrically arranged and fixedly connected to the front and rear walls of the adsorption perforated plate 7. A movable support plate 802 is hinged to the end of the mounting plate 801 away from the adsorption perforated plate 7. The inkjet printer 3 has mounting grooves 803 that correspond to the positions and specifications of the mounting plates 801 and the movable support plate 802. A snap-fit ​​block 804 is fixedly connected to the inner side of the movable support plate 802. A positioning slot 805 is provided on one side of the snap-fit ​​block 804. A snap-fit ​​groove 806 that corresponds to the position and specifications of the snap-fit ​​block 804 is provided in the mounting groove 803. A reset groove 807 and a movable groove 808 are provided on one side of the snap-fit ​​groove 806. A moving groove 809 is provided on the front side of the reset groove 807. A reset spring 810 is fixedly connected to the inner wall of the reset groove 807 away from the snap-fit ​​groove 806. One end of the near-slot 806 is fixedly connected to a reset support plate 811 that is slidably connected to a reset slot 807. The end of the reset support plate 811 near the slot 806 is fixedly connected to a positioning rod 812 that passes through the movable slot 808 and extends into the slot 806, and corresponds to the position of the positioning slot 805 and matches its specifications. A connecting rod 813 that extends outward through the movable slot 809 is fixedly connected to the reset support plate 811. A movable handle 814 is fixedly connected to the end of the connecting rod 813 away from the reset support plate 811. The mounting assembly 8 can provide good installation capability between the adsorption orifice plate 7 and the inkjet printer 3. Therefore, it can not only ensure the structural stability between the adsorption orifice plate 7 and the inkjet printer 3 during normal use, but also disassemble and replace the adsorption orifice plate 7 when it is damaged, thereby reducing the difficulty of subsequent maintenance.

[0026] Workflow: First, power on all electrical appliances and connect them to external controllers. Place the polarizing film on the suction plate 7 of the inkjet printer 3. Then, start the negative pressure fan unit 4 to draw air from top to bottom. Negative pressure is created in the first and second channels 5 and 6 through the suction, ultimately adsorbing the polarizing film through the suction plate 7. This ensures good positioning of the polarizing film, preventing it from shifting or falling during inkjet printing, thus avoiding affecting the printing effect and efficiency. After positioning, the inkjet printer head is adjusted using the electric slide rail in the inkjet printer assembly 9. Then, the inkjet printer head and connecting soft... The ink cartridge ejects ink from the ink tank to perform inkjet printing on the polarizer. This inkjet printing facilitates product traceability and quality control, production process management, anti-counterfeiting and brand protection, process and subsequent processing assistance, and after-sales service and maintenance. The mounting component 8 provides good installation capability between the adsorption orifice plate 7 and the inkjet printing station 3. Therefore, it not only ensures the structural stability between the adsorption orifice plate 7 and the inkjet printing station 3 during normal use, but also allows for disassembly and replacement of the adsorption orifice plate 7 if it is damaged, thereby reducing the difficulty of subsequent maintenance. During installation, the adsorption orifice plate 7 is first placed into the second through slot 6 from the top of the inkjet printing station 3. At this time, the mounting support plate 801 is locked in the mounting slot 803. Then, the movable support plate 802 is rotated into the mounting slot 803, and the snap-fit ​​block 804 on it is inserted into the snap-fit ​​groove 806. The insertion of the snap-fit ​​block 804 will press the positioning rod 812 located in the snap-fit ​​groove 806. After being pressed, the positioning rod 812 will drive the reset support plate 811 to move into the reset groove 807 in the movable slot 808. The movement of the reset support plate 811 will simultaneously press the reset spring 810 until the snap-fit ​​block 804 is fully inserted into the snap-fit ​​groove 806, at which point the positioning slot 805 on it corresponds to the position of the positioning rod 812. At this time, the pressing force of the snap-fit ​​block 804 on the positioning rod 812 disappears, and the reset spring 810 is then released. The self-rebound force drives the reset support plate 811 and the positioning rod 812 to move and reset towards the snap-fit ​​groove 806. Finally, the positioning rod 812 is inserted into the positioning slot 805 for positioning and snap-fit. When disassembling the adsorption plate 7, first pull the moving handle 814 towards the reset groove 807. The moving handle 814 drives the reset support plate 811 and the positioning rod 812 to move in the moving groove 809 through the connecting support rod 813, thereby pulling the positioning rod 812 out of the positioning slot 805. At this time, the positioning rod 812's limitation on the snap-fit ​​block 804 disappears. Finally, rotate the movable support plate 802 until the snap-fit ​​block 804 is disengaged from the snap-fit ​​groove 806, and then move the adsorption plate 7 upward and remove it.
