[0043] Embodiment 1 like Figure 1 As shown, the present application provides a dual-platform multifunctional circuit board inkjet printing device, comprising: a bed 1 and an inkjet system 4, a first workbench 2 for placing a large-size circuit board and a second workbench 3 for placing a small-size circuit board are sequentially arranged on the bed 1 along a first direction, and a first driving mechanism 21 is arranged between the first workbench 2 and the bed 1 (see Figure 3 ), to drive the first workbench 2 to move along the second direction of the bed body 1, a second driving mechanism 31 is provided between the second workbench 3 and the bed body 1, to drive the second workbench 3 to move along the second direction of the bed body 1, and the inkjet system 4 is movably installed on the bed body 1 in the first direction; when the first driving mechanism 21 drives the first workbench 2 to the first printing position, the inkjet system 4 moves to the first printing position for printing; when the second driving mechanism 31 (see Figure 4 ) drives the second workbench 3 to the second printing position, and the inkjet system 4 moves to the second printing position for printing. It should be noted that in this embodiment, the inkjet system 4 can be moved in the first direction for printing. When the first workbench 2 or the second workbench 3 reaches the first printing position or the second printing position respectively, the inkjet system 4 is started for printing, and at the same time, the first drive mechanism 21 or the second drive mechanism 31 is used to drive the first workbench 2 or the second workbench 3 to move along the second direction respectively, and they work together to complete the printing of the large-size circuit board or the small-size circuit board on the first workbench 2 or the second workbench 3.

[0044] During actual use, the first workbench 2 is used to place large-size circuit boards, and the second workbench 3 is used to place small-size circuit boards. When it is necessary to print a large-size circuit board, the large-size circuit board is placed on the first workbench 2, and the first driving mechanism 21 moves the first workbench 2 with the large-size circuit board placed thereon to the first printing position along the second direction, and starts the inkjet system 4 to print along the first direction. 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 it is necessary to print a small-size circuit board, the small-size circuit board is placed on the second workbench 3, and the second driving mechanism 31 moves the second workbench 3 with the small-size circuit board placed thereon to the first printing position along the second direction, and starts the inkjet system 4 to print along the first direction. 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 printing device in the present invention can realize the printing of large-size circuit boards or small-size circuit boards according to the needs, thereby increasing the application scope of the equipment, reducing the floor space occupied by multiple devices, and improving production efficiency. The inkjet printing device of the present invention has a high degree of integration and can print large-size circuit boards or small-size circuit boards, thereby reducing equipment purchases and reducing production costs.

[0045] Further references Figure 1 In this embodiment, a mounting base 9 is provided on the bed 1, and the mounting base 9 includes two legs 92 arranged in parallel on both sides of the bed 1 and a crossbeam 91 connected to the top of the two legs 92, the crossbeam 91 is arranged along the first direction, and the two legs 92 are located in the middle of the bed 1 in the second direction. The crossbeam 91 is used to separate the bed 1 into a placement area and a processing area, and the length of the placement area and the processing area in the second direction is greater than the length of the first workbench 2 or the second workbench 3.

[0046] Manually controlling the first driving mechanism 21 to drive the first workbench 2 to the first printing position or controlling the second driving mechanism 31 to drive the second workbench 3 to the second printing position may result in errors, which may affect the printing results. Figures 2 to 4As shown, in this embodiment, the dual-platform multifunctional circuit board high-speed inkjet printing device also includes a visual inspection system for identification positioning and printing detection, and the visual inspection system includes a visual moving mechanism, a first CCD visual detector 51 and a second CCD visual detector 52. The visual moving mechanism is installed on the bed 1, and the visual moving mechanism that drives the first CCD visual detector 51 and the second CCD visual detector 52 to move in the first direction drives and connects the first CCD visual detector 51 and the second CCD visual detector 52. Specifically, in this embodiment, the visual moving mechanism includes a visual linear guide 531, a first visual linear motor 532 and a second visual linear motor 533. The visual linear guide 531 is installed on the beam 91 and is located on one side of the beam 91 in the second direction. The mover of the first visual linear motor 532 is installed on the visual linear guide 531 through a slider, and the first visual linear motor 532 is connected to the first CCD visual detector 51. The mover of the second visual motor is installed on the visual linear guide 531 through a slider, and the second visual motor is connected to the second CCD visual detector 52. It should be noted that the present embodiment further includes a controller, which is electrically connected to the first driving mechanism 21, the second driving structure, the first visual linear motor 532, the second visual linear motor 533, the first CCD visual detector 51 and the second CCD visual detector 52 respectively.

[0047] During actual use, the controller controls the first drive mechanism 21 or the second drive mechanism 31 to drive the first workbench 2 or the second workbench 3 to the first printing position or the second printing position, and at the same time 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 the detection position respectively. 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 small 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; improve the printing accuracy and ensure product quality. It is worth mentioning that the first CCD visual detector 51 and the second CCD visual detector 52 can obtain the image information after the printing is completed, and transmit the image information to the controller. The controller compares the image information after the printing with the preset printing image, and feeds back the comparison results to the operation panel for the operator to view. It is still necessary to explain that the first CCD visual inspection instrument 51 and the second CCD visual inspection instrument 52 can also be used for regular detection and calibration of equipment accuracy. A glass calibration plate is placed on each of the first workbench 2 and the second workbench 3. The coordinates of the dots on the calibration plate are collected by the first CCD visual inspection instrument 51 and the second CCD visual inspection instrument 52, and compared with the coordinates of the original file. According to the coordinate fitting correction, the equipment accuracy is calibrated regularly to make the equipment performance more stable and reliable. It should be noted that the existing image analysis and comparison method is used for image acquisition, analysis and comparison in this embodiment, which will not be explained in detail here.

[0048] Specifically, in this embodiment, the first CCD vision detector 51 and the second CCD vision detector 52 use line scanning cameras and tunnel light sources. The width of the line scanning camera is 350 mm. The two sets of visual systems formed by the first CCD vision detector 51 and the second CCD vision detector 52 can collect synchronously, and the maximum collection width is 700 mm. After printing, the first CCD vision detector 51 and the second CCD vision detector 52 collect at the same time, which effectively avoids multiple collections affecting production efficiency.

[0049] like Figure 1 and Figure 4As shown, in a specific example provided by the present application, the inkjet system 4 includes an inkjet moving mechanism 42, a nozzle control mechanism 41 and an ink supply mechanism 43; the inkjet moving mechanism 42 installed on the bed 1 has an inkjet slider moving along a first direction, and the nozzle control mechanism 41 is connected to the inkjet slider; the ink supply mechanism 43 for providing ink for the nozzle control mechanism 41 is installed on the bed 1. Specifically, the inkjet moving mechanism 42 includes an inkjet linear motor 422 and an inkjet linear guide 421, the inkjet linear guide 421 is installed on the crossbeam 91 and is located on the other side opposite to the visual moving mechanism, the mover of the inkjet linear motor 422 is installed on the inkjet linear slider through a slider, the inkjet linear motor 422 is connected to the nozzle control mechanism 41, and the inkjet linear motor 422 is electrically connected to the controller; the controller is electrically connected to the nozzle control mechanism 41 and the ink supply mechanism 43.

[0050] During actual use, the controller controls the inkjet straight line to drive the nozzle control mechanism 41 to move to the initial printing position. The controller controls the nozzle control mechanism 41 to print, and at the same time controls the ink supply mechanism 43 to provide ink for the nozzle control mechanism 41 to improve the printing accuracy; the ink supply mechanism 43 provides ink for the nozzle control mechanism 41 to ensure the continuity of printing and improve the printing efficiency.

In actual use, the cleaning mechanism 44 is mainly used for cleaning and maintaining the nozzles in the nozzle control mechanism 41, thereby increasing the service life of the nozzle control mechanism 41 and ensuring the printing effect.

[0052] like Figure 2 and Figure 5As shown, in a specific example provided by the present application, the dual-platform multifunctional circuit board high-speed inkjet printing device also includes a curing system 7, which includes a curing support 71, a first curing component 72 and a second curing component 73; the curing support 71 is installed on the bed 1 and is located between the first workbench 2 and the second workbench 3; the first curing component 72 and the second curing component 73 are respectively installed on both sides of the curing support 71 along the first direction, and the first curing component 72 and the second curing component 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 component 72 and the second curing component 73 is a UV lamp. In actual use, the UV lamp in the first curing component 72 irradiates the printed circuit board on the first workbench 2, which enhances the bonding force between the ink and the surface of the large-size circuit board, and the UV lamp in the second curing component 73 irradiates the printed circuit board on the second workbench 3, which enhances the bonding force between the ink and the surface of the small-size circuit board, improves the stability of printing, and ensures that the patterns of the large-size circuit board and the small-size circuit board after printing can be preserved for a long time.

[0053] like Figure 1 and Figure 5 As shown, in a specific example provided by the present application, the dual-platform multifunctional circuit board high-speed inkjet printing device also includes a thickness measuring component 8, the thickness measuring component 8 includes a thickness measuring support 81, a first thickness measuring sensor 82 and a second thickness measuring sensor 83; the thickness measuring support 81 located between the first workbench 2 and the second workbench 3 is installed on the bed 1, and the thickness measuring support 81 extends a first support beam and a second support beam on both sides of the first direction, and the first support beam and the second support beam are respectively located on the first workbench 2 and the second workbench 3; the first thickness measuring sensor 82 for monitoring the thickness of the circuit board on the first workbench 2 and the second sensor for monitoring the thickness of the circuit board on the second workbench 3 are respectively installed on the first support beam and the second support beam.

[0054] 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 feed the monitoring results back to the controller. The controller adjusts the distance between the nozzle in the nozzle control mechanism 41 and the large-size circuit board or the small-size circuit board according to the monitoring results to improve the printing accuracy.

[0055] like Figure 3 and Figure 4As shown, in a specific example provided by the present application, the first driving mechanism 21 includes a first linear motor 212 and a first linear guide assembly 211, the first linear guide assembly 211 is installed on the bed 1, the mover of the first linear motor 212 is installed on the first linear guide assembly 211 through a slider, and the first linear motor 212 is connected to the first workbench 2; the first linear motor 212 drives and connects to the first linear guide assembly 211; the second driving mechanism 31 includes a second linear motor 312 and a second linear guide assembly 311, the second linear guide assembly 311 is installed on the bed 1, the mover of the second linear motor 312 is installed on the second linear guide assembly 311 through a slider, and the second linear motor 312 is connected to the second workbench 3.

[0056] During actual use, the controller controls the first linear motor 212 or the second linear motor 312 to rotate forward or reverse, and the corresponding slider performs reciprocating motion on the first linear guide rail or the second linear guide rail assembly 311, thereby causing the first workbench 2 installed on the first linear motor 212 or the second workbench 3 installed on the second linear motor 312 to reciprocate. In other embodiments, the first drive mechanism 21 and the second drive mechanism 31 use a screw nut assembly to achieve the linear motion of the first workbench 2 and the second workbench 3; therefore, the present application does not limit the specific structures of the first drive mechanism 21 and the second drive mechanism 31.

[0057] like Figures 5 to 7 As shown, in a specific example provided by the present 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 mechanism includes a first moving mechanism 22 and a first edge pressing assembly 24 respectively arranged on both sides of the first workbench 2 in the first direction; the first moving mechanism 22 and the first edge pressing assembly 24 are located inside the first workbench 2, the first moving mechanism 22 driving the first edge pressing assembly 24 to move in the first direction is located inside the first workbench, the first moving mechanism 22 drives the first edge pressing assembly 24 to drive, and a first slide 201 for the first edge pressing assembly 24 to move is provided on the first workbench 2; when the large-size circuit board is placed on the first workbench 2, the first moving mechanism 22 drives the first edge pressing assembly 24 to move along the first direction close to the side of the large-size circuit board until the first edge pressing assembly 24 is located above the large-size circuit board, and the first moving mechanism 22 stops driving the first edge pressing assembly 24. Specifically, the first edge pressing assembly 24 includes a first moving rod 242 located in the first sliding groove 201 and a first pressing plate 241 placed on the top of the first moving rod 242 .
