Description

Technical Field

[0001] This utility model relates to the field of printing inkjet technology, specifically to a worktable that uses a line as an edge-pressing full adsorption stage. Background Technology

[0002] In the field of inkjet printing technology, existing inkjet workstations generally use an integrated adsorption platform with a waist-shaped hole as the core load-bearing component. The original design intention of this type of adsorption platform is to achieve rapid fixation of the printing material through the cooperation of the waist-shaped hole and the negative pressure adsorption system. Its waist-shaped hole structure is mainly used to adapt to the adjustment of the adsorption range for different sized materials, and to take into account the airflow efficiency to ensure the uniformity of adsorption force. However, in actual use, when the edge of the printing material is exactly inside the waist-shaped hole, it will cause deformation and unevenness, affecting the print quality.

[0003] To address this, the applicant proposes a method that uses a line as an edge-pressing full-adsorption workbench. The line clamps both ends to press the plate, and the platform uses negative pressure adsorption and diagonal edge positioning assistance to fundamentally solve the flatness problem caused by the edge covering of the waist-shaped hole in traditional platforms, thus significantly improving the stability and consistency of printing quality.

[0020] In the field of inkjet printing technology, existing inkjet workstations generally use an integrated adsorption platform with a waist-shaped hole as the core load-bearing component. The original design intention of this type of adsorption platform is to achieve rapid fixation of the printing material through the cooperation of the waist-shaped hole and the negative pressure adsorption system. Its waist-shaped hole structure is mainly used to adapt to the adjustment of the adsorption range for different sized materials, and to take into account the airflow efficiency to ensure the uniformity of adsorption force. However, in actual use, when the edge of the printing material is exactly inside the waist-shaped hole, it will cause deformation and unevenness, affecting the print quality.

[0021] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3As shown, a workbench using a line as an edge-pressing device includes a table frame assembly 100. The table frame assembly 100 includes a first mounting plate 103. Multiple columns 104 are fixedly mounted on the upper end of the first mounting plate 103 by bolts. The upper ends of the multiple columns 104 are fixedly mounted on the same table surface 102 by bolts. A sealing plate 101 is glued to the upper end of the table surface 102. A support plate 105 is fixedly mounted on one side between the table surface 102 and the first mounting plate 103 by bolts. Multiple first pagoda connectors 107 are fixedly mounted on the lower end of the table surface 102 by bolts. Four first pagoda connectors 107 are provided at the four corners of the lower end of the table surface 102, and two are provided inside, for a total of six. A first clamp 106 is provided at the lower end of each of the multiple first pagoda connectors 107. Slide rails 108 are symmetrically fixed on the first mounting plate 103. The first clamp 106 can firmly fix the air duct to the lower end of the pagoda connector, preventing the hose from falling off due to airflow pressure, vibration, etc. during the operation of the adsorption workbench, and ensuring the stability of the connection. At the same time, the tightening effect of the first clamp 106 can also ensure the sealing of the connection and prevent gas leakage. This is crucial for the adsorption performance of the full adsorption workbench, because leakage may lead to insufficient adsorption force and affect the normal operation of the workbench.

[0022] Please see Figure 4 As shown, multiple wire pressing components 200 are provided on two symmetrical slide rails 108. In this embodiment, there are two wire pressing components 200. One of the wire pressing components 200 is driven to reciprocate on the slide rail 108 by a transmission device 300, and the other wire pressing component 200 is reciprocated by a second cylinder 500 symmetrically fixed to the upper end of the first mounting plate 103. The line voltage assembly 200 includes cylinder mounting plates 207 symmetrically arranged on slide rail 108. A first cylinder 206 is fixedly mounted on each of the two cylinder mounting plates 207 by bolts. A pipe connector 205 is fixedly provided on one side of each of the two first cylinders 206.

The middle part of one side of the cylinder mounting plate 207 is fixed with a first connecting plate 201 by bolts. In this embodiment, the external air passage controls the extension and retraction of the first cylinder 206 through the air pipe connector 205, thereby driving the linkage structure composed of the adapter plate 208, the second connecting plate 204 and the pressure plate 203 to move. The left and right symmetrical pressure plates 203 and the second connecting plate 204 jointly press the wire body 202 with bolts. When the first cylinder 206 is driven, the wire body 202, as the core component of the edge pressing, moves accordingly to achieve pressing and positioning of the edge of the plate.

The power source of the transmission device 300 consists of a stepper motor 301 and a reducer 302. The reducer 302 is fixed to one end of the second mounting plate 303 at the lower end of the table 102 by bolts. One end of the reducer 302 is fixedly connected to the stepper motor 301. The other end of the reducer 302 is coaxially fixedly connected to a coupling 304 on one side of the second mounting plate 303. One end of the coupling 304 is fixedly provided with a rotating shaft 305. The two ends of the rotating shaft 305 are symmetrically mounted with fixed brackets 306 through bearings. The two symmetrical fixed brackets 306 are connected to the table 102. Adjustment seats 310 are symmetrically arranged at the lower end of the platform 102. The positions of the two adjustment seats 310 and the two fixed brackets 306 are arranged one-to-one. A tensioning seat 308 is provided on one side of each of the two adjustment seats 310. The tensioning seat 308 is used to adjust the adjustment seats 310 so as to adjust the state of the timing belt 307. A driven wheel 309 is rotatably arranged at the upper end of each of the two adjustment seats 310. A driving wheel 311 is symmetrically arranged on the outer surface of the rotating shaft 305. A timing belt 307 is arranged between each driving wheel 311 and its corresponding driven wheel 309.

In this embodiment, multiple first pagoda connectors 107 and second pagoda connectors 401 are connected by flexible hoses. In this embodiment, there are a total of six connection points. Four first pagoda connectors 107 are located at the four corners of the lower end of the tabletop 102, and two are located at the middle of the bottom of the tabletop 102. The remaining two pagoda connectors of the tabletop vacuum integrated block assembly 400 are connected to the negative pressure fan.

[0025] Positioning devices are provided on both sides of the table 102 to better position the board at its starting position. The positioning devices are raised by lifting cylinders to position the board when it is placed and lowered when printing, without affecting the printing process. The entire table 102 is equipped with suction holes.

[0026] Example 3: Based on Examples 1 and 2, please refer to... Figures 1-7 As shown, the working principle of this utility model is as follows: During use, the wire pressing assembly 200 is adjusted according to the size of the board. The two wire bodies 202 of each set of wire pressing assemblies 200 (the distance between each set of wire bodies 202 is not greater than the width of the non-printing area of ​​the board) can better press the edge of the board. After pressing the edge of the board, a stable negative pressure is formed by the table vacuum integrated block assembly 400. Combined with multiple first pagoda connectors 107 and second pagoda connectors 401 and the sealing structure, the adsorption force is guaranteed. The wire body 202, as the edge pressing core, can accurately press the edge of the board under the drive of the first cylinder 206, realizing the synergistic cooperation of adsorption and edge pressing, ensuring the stable positioning of the board and improving the printing quality. During printing, the wire body 202 presses on the board until the printing is completed. Then, the wire body 202 is lifted and moved horizontally, and the printed board is removed.
