[0051] In actual use, the first workbench 2 is used for placing a large-size circuit board, and the second workbench 3 is used for placing a small-size circuit board. When printing of a large-size circuit board is needed, the large-size circuit board is placed on the first workbench 2, the first driving mechanism 21 drives the first workbench 2 on which the large-size circuit board is placed to move in the second direction to the first printing position, the inkjet system 4 is started to perform printing in the first direction, and at the same time, the first driving mechanism 21 continues to drive the first workbench 2 to move in the second direction, to complete the printing of the large-size circuit board on the first workbench 2. When printing of a small-size circuit board is needed, the small-size circuit board is placed on the second workbench 3, the second driving mechanism 31 drives the second workbench 3 on which the small-size circuit board is placed to move in the second direction to the first printing position, the inkjet system 4 is started to perform printing in the first direction, and at the same time, the second driving mechanism 31 continues to drive the second workbench 3 to move in the second direction, to complete the printing of the small-size circuit board on the second workbench 3.

The inkjet printing device in the embodiment has high integration degree, can perform printing of a large-size circuit board or a small-size circuit board, reduces the purchase of devices, and reduces production cost.

[0052] Further referring to Figure 1 In the embodiment, the bed body 1 is provided with a mounting seat 9, the mounting seat 9 includes two supporting legs 92 arranged in parallel on both sides of the bed body 1 and a cross beam 91 connected to the top of the two supporting legs 92, the cross beam 91 is arranged in the first direction, and the two supporting legs 92 are located in the middle part of the bed body 1 in the second direction. The cross beam 91 is used to separate the bed body 1 into a placing area and a processing area, and the lengths of the placing area and the processing area in the second direction are greater than the lengths of the first workbench 2 or the second workbench 3.

[0053] Manual control of the first driving mechanism 21 to drive the first workbench 2 to the first printing position or control of the second driving mechanism 31 to drive the second workbench 3 to the second printing position has errors, which affects the printing result. Therefore, as shown in Figures 2 to 4As shown, in the embodiment, the double-platform multifunctional circuit board high-speed inkjet printing device further comprises a visual detection system for identification, positioning and jet printing detection. The visual detection system comprises a visual moving mechanism, a first CCD visual detection instrument 51 and a second CCD visual detection instrument 52. The visual moving mechanism is installed on the bed body 1. The visual moving mechanism drivingly connects the first CCD visual detection instrument 51 and the second CCD visual detection instrument 52. Specifically, in the embodiment, the visual moving mechanism comprises a visual linear guide rail 531, a first visual linear motor 532 and a second visual linear motor 533. The visual linear guide rail 531 is installed on the cross beam 91 and located on one side of the cross beam 91 in the second direction.

[0054] In actual use, the controller controls the first driving mechanism 21 or the second driving mechanism 31 to drive the first workbench 2 or the second workbench 3 to reach the first printing position or the second printing position, and controls the first visual linear motor 532 and the second visual linear motor 533 to drive the first CCD visual detector 51 and the second CCD visual detector 52 to reach the detection position respectively, so that the first CCD visual detector 51 and the second CCD visual detector 52 obtain the positioning points of the large-size circuit board or the small-size circuit board on the first workbench 2 or the second workbench 3, to control the inkjet system 4 to move to the first printing position or the second printing position to start printing; the printing precision is improved, and the product quality is ensured. It is worth mentioning that the first CCD visual detector 51 and the second CCD visual detector 52 can obtain the image information after printing is completed, and transmit the image information to the controller, the controller compares the image information after printing is completed with the preset printing image, and feeds back the comparison result to the operation panel, so that the operator can check. It still needs to be explained that the first CCD visual detector 51 and the second CCD visual detector 52 can also be used for periodic detection and calibration of equipment precision. One glass calibration plate is placed on the first workbench 2 and the second workbench 3 respectively, the coordinates of the dots on the calibration plate and the original file coordinates are compared by the first CCD visual detector 51 and the second CCD visual detector 52, the coordinates are fitted and corrected, and the equipment precision is calibrated periodically, so that the equipment performance is more stable and reliable. It needs to be explained that the existing image analysis and comparison method is used for image acquisition, analysis and comparison in the embodiment, which will not be expanded here.

[0055] Specifically, the first CCD visual detector 51 and the second CCD visual detector 52 in the embodiment adopt a line scanning camera and a tunnel light source, the line scanning camera has a width of 350 mm, and the two groups of visual systems formed by the first CCD visual detector 51 and the second CCD visual detector 52 can be synchronously collected, the maximum collection width is 700 mm, the first CCD visual detector 51 and the second CCD visual detector 52 are collected at the same time after printing, and the influence of multiple collection on production efficiency is effectively avoided.

[0056] As Figure 1 and Figure 4As shown, in a specific embodiment provided in this application, the inkjet system 4 includes an inkjet moving mechanism 42, a printhead control mechanism 41, and an ink supply mechanism 43.

The inkjet linear motor 422 is connected to the printhead control mechanism 41 and electrically connected to a controller. The controller is electrically connected to the printhead control mechanism 41 and the ink supply mechanism 43.

[0057] In actual use, the controller controls the inkjet linear motor to move the printhead control mechanism 41 to the initial printing position.

Specifically, in this embodiment, the curing source of the first curing assembly 72 and the second curing assembly 73 is a UV lamp. In actual use, the UV lamp in the first curing assembly 72 irradiates the printed circuit board on the first workbench 2 after printing, thereby enhancing the binding force between the ink and the surface of the large-size circuit board, and the UV lamp in the second curing assembly 73 irradiates the printed circuit board on the second workbench 3 after printing, thereby enhancing the binding force between the ink and the surface of the small-size circuit board, improving the stability of printing, and ensuring that the patterns of the large-size circuit board and the small-size circuit board after printing can be preserved for a long time.

[0060] As shown in the drawings, Figure 1 and Figure 5 As shown in the drawings, in one specific example provided by the present application, the double-platform multifunctional circuit board high-speed inkjet printing device further comprises a curing system 7, which comprises a curing support 71, a first curing assembly 72 and a second curing assembly 73; the curing support 71 is installed on the bed body 1 and located between the first workbench 2 and the second workbench 3; the first curing assembly 72 and the second curing assembly 73 are respectively installed on the two sides of the curing support 71 along the first direction, and the first curing assembly 72 and the second curing assembly 73 are respectively located above the first workbench 2 and the second workbench 3. Specifically, in this embodiment, the curing source of the first curing assembly 72 and the second curing assembly 73 is a UV lamp. In actual use, the UV lamp in the first curing assembly 72 irradiates the printed circuit board on the first workbench 2 after printing, thereby enhancing the binding force between the ink and the surface of the large-size circuit board, and the UV lamp in the second curing assembly 73 irradiates the printed circuit board on the second workbench 3 after printing, thereby enhancing the binding force between the ink and the surface of the small-size circuit board, improving the stability of printing, and ensuring that the patterns of the large-size circuit board and the small-size circuit board after printing can be preserved for a long time.

[0061] In actual use, the first thickness sensor 82 and the second thickness sensor 83 are respectively used to monitor the thickness of the large-size circuit board on the first workbench 2 or the small-size circuit board on the second workbench 3, and the monitoring results are fed back to the controller, and the controller adjusts the distance between the nozzle and the large-size circuit board or the small-size circuit board in the nozzle control mechanism 41 according to the monitoring results, thereby improving the printing precision.

[0062] As shown in the drawings, Figure 3 and Figure 4As shown, in a specific embodiment provided in this application, the first drive mechanism 21 includes a first linear motor 212 and a first linear guide assembly 211. The first linear guide assembly 211 is mounted on the bed 1. The mover of the first linear motor 212 is mounted on the first linear guide assembly 211 via a slider. The first linear motor 212 is connected to the first worktable 2. The first linear motor 212 drives the first linear guide assembly 211.

[0063] In actual use, the controller controls the first linear motor 212 or the second linear motor 312 to rotate forward or reverse, and through their corresponding sliders, they reciprocate on the first linear guide rail or the second linear guide rail assembly 311, thereby causing the first worktable 2 mounted on the first linear motor 212 or the second worktable 3 mounted on the second linear motor 312 to reciprocate. In other embodiments, the first drive mechanism 21 and the second drive mechanism 31 use a lead screw and nut assembly to realize the linear motion of the first worktable 2 and the second worktable 3; therefore, this application does not limit the specific structure of the first drive mechanism 21 and the second drive mechanism 31.

[0064] like Figures 5 to 9 As shown in the specific embodiment provided in this application, a first edge pressing mechanism and a second edge pressing mechanism for pressing the circuit board are respectively provided on the first workbench 2 and the second workbench 3.

The first edge pressing assembly 24 is connected to the first edge pressing slider and moves with the first edge pressing slider. The first workbench 2 is provided with a first sliding groove 201 for moving the first edge pressing assembly 24. When the circuit board is placed on the first workbench 2, the first moving mechanism drives the first edge pressing slider to move towards the side of the circuit board until the first edge pressing assembly 24 is above the circuit board, at which point the first moving mechanism 22 stops driving the first edge pressing slider. Specifically, the first edge pressing assembly 24 includes a first moving rod 242 located within the first sliding groove 201 and a first pressing plate 241 placed on top of the first moving rod 242.

[0065] In actual use, when the large-size circuit board is not placed on the first workbench 2, the controller controls the first moving mechanism 22 to control the first edge pressing assembly 24 to move away from the first workbench 2; when the large-size circuit board is placed on the first workbench 2, the controller controls the first moving mechanism 22 to control the first edge pressing assembly 24 to move towards the workbench, the first moving rod 242 moves in the first sliding groove 201 until the first pressing plate 241 is above the large-size circuit board, limiting the movement of the large-size circuit board in the Z direction, ensuring the stability during the inkjet printing process and improving the inkjet printing precision.
