If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0036] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0037] Reference Figures 1 to 6This utility model provides a circuit board inkjet printing device, including a first positioning mechanism 200, a second positioning mechanism 300, and an inkjet device 400. The first positioning mechanism 200 includes a tray 210 and a first positioning component 220, a second positioning component 230, a third positioning component 240, and a first reset component 260 connected to the tray 210. Specifically, the first positioning component 220, the second positioning component 230, and the third positioning component 240 are respectively disposed on the tray 210 near the left side, the front side, and the rear side. The component 240, when engaged, can define three sides of the circuit board; the third positioning component 240 includes a plurality of first positioning blocks 241 movably connected to the tray 210; the first reset component 260 includes a pusher 262, which can push all the first positioning blocks 241 to move to achieve reset; the second positioning mechanism 300 is movably connected below the first positioning mechanism 200; the inkjet device 400 is disposed above the second positioning mechanism 300; specifically, the second positioning mechanism 300 is mounted on the machine base 100, and the first positioning mechanism 200 is movably disposed between the second positioning mechanism 300 and the inkjet device 400.

[0038] During operation, the left and front sides of the circuit board are respectively attached to the first positioning component 220 and the second positioning component 230. Then, the multiple first positioning blocks 241 of the third positioning component 240 are moved and attached to the rear side of the circuit board to achieve positioning and fixation of the circuit board to be printed. The circuit board is fixed on the first positioning mechanism 200, and then the first positioning mechanism 200 is moved on the second positioning mechanism 300 and finally moved to the designated position on the second positioning mechanism 300. At this time, the first positioning mechanism 200 is located directly below the inkjet device 400. The inkjet device 400 is used to print on the circuit board. After printing is completed, the first positioning mechanism 200 is moved away from directly below the inkjet device 400, and the multiple first positioning blocks 241 are quickly reset using the first reset component 260. This allows for quick removal of the printed circuit board, resulting in high work efficiency.

[0039] The left, front, and rear sides of the circuit board can respectively abut the first positioning component 220, the second positioning component 230, and the third positioning component 240 to fix the circuit board to be printed. Since the positions of the first positioning component 220 and the second positioning component 230 are fixed, and the left and front sides of the circuit board can always abut the first positioning component 220 and the second positioning component 230 respectively, the circuit board can also be positioned. By pushing the pusher 262 of the first reset component 260, all the first positioning blocks 241 can be moved to reset all the first positioning blocks 241. The first positioning blocks 241 are reset efficiently and quickly, so that the printed circuit board can be quickly removed, improving the production efficiency of circuit board printing.

[0040] According to some embodiments of this application, refer to Figure 2 and Figure 3 The third positioning component 240 also includes a plurality of first waist-shaped holes 246, through which the first positioning block 241 passes. The first reset component 260 also includes an operating handle 261, which is movably connected to the support plate 210. The lower end of the operating handle 261 is fixedly connected to one end of the pusher 262. The pusher 262 is located below the support plate 210 and spans all the first waist-shaped holes 246. The operating handle 261 is used to push the pusher 262, thereby improving the ease of operation of the first reset component 260.

[0041] It is understood that in some other embodiments, the tray 210 is also provided with a second oblong hole 264, through which the operating handle 261 passes and is movably connected to the second oblong hole 264.

[0042] Understandably, referring to Figure 3 and Figure 5 In some other embodiments, the first reset assembly 260 further includes a reset auxiliary slide 265 and a reset auxiliary slider 266. The reset auxiliary slider 266 is fixedly connected to the end of the pusher 262 away from the operating handle 261, and the reset auxiliary slider 266 is slidably connected to the reset auxiliary slide 265 to improve the smoothness and reliability of the movement of the pusher 262.

[0043] Furthermore, referring to Figure 6 The first positioning block 241 is provided with a first stepped portion 242, and the first oblong hole 246 is provided with a second stepped portion 247. The first stepped portion 242 is matched and disposed above the second stepped portion 247. Through the cooperation of the first stepped portion 242 and the second stepped portion 247, the first positioning block 241 can be movably disposed in the first oblong hole 246. The first positioning block 241 can also be disengaged upward from the first oblong hole 246. By removing the first positioning block 241 upward and then placing it back in its original position, the reset path of the first positioning block 241 is enriched.

[0044] Furthermore, both the first step portion 242 and the second step portion 247 are provided with anti-slip textures 248 to increase the friction between the first positioning block 241 and the first waist-shaped hole 246, thereby improving the positioning reliability of the first positioning block 241.

[0045] Furthermore, referring to Figure 4The pusher 262 has a first inclined surface 243 on its upper part and a second inclined surface 263 corresponding to the first inclined surface 243 on its lower part. When the pusher moves backward toward the first positioning block 241 to reset the first positioning block 241, the pushing force of the first inclined surface 243 on the second inclined surface 263 has an upward component, which can push the second inclined surface 263 upward, thereby causing the first positioning block 241 to slightly disengage from the first waist-shaped hole 246. At this time, the anti-slip texture 248 of the first step 242 and the anti-slip texture 248 of the second step 247 do not contact each other, reducing friction and making the reset operation easier.

[0046] According to some embodiments of this application, refer to Figure 4 The first positioning block 241 is provided with a first limiting member 244, and the upper end of the first limiting member 244 is provided with a limiting part 245. The limiting part 245 is used to limit the upper surface of the circuit board, so that the circuit board is close to the support plate 210, ensuring the reliability of the circuit board positioning and fixing.

[0047] Furthermore, the first limiting member 244 is movably connected to the first positioning block 241. Specifically, the first limiting member 244 is a screw, and the first positioning block 241 is provided with threads. The screw is connected by the threads, allowing the screw to be rotatably connected to the first positioning block 241. Moreover, the height of the screw can be adjusted by rotating it, thereby adjusting the limiting height of the limiting part 245 to adapt to circuit boards of different thicknesses.

[0048] According to some embodiments of this application, refer to Figures 1 to 3 The first positioning mechanism 200 also includes a fourth positioning component 250 and a second reset component 270. The fourth positioning component 250 includes a second positioning block 251. The second reset component 270 and the second positioning block 251 are both movably connected to the support plate 210. The second reset component 270 can push the second positioning block 251 to move to achieve reset, thereby improving the reliability of the circuit board's fixation and positioning.

[0049] Specifically, the fourth positioning component 250 and the third positioning component 240 adopt the same structure, the first reset component 260 and the second reset component 270 adopt the same structure, and the fourth positioning component 250 is disposed on the tray 210 near the right side to limit the right side of the circuit board.

[0050] According to some embodiments of this application, both the first positioning component 220 and the second positioning component 230 include a plurality of third positioning blocks 221, which limit the left side and front side of the circuit board.

[0051] Specifically, the third positioning block 221 is provided with a second limiting member to limit the upper surface of the circuit board.

[0052] According to some embodiments of this application, refer to Figure 1 The second positioning mechanism 300 includes a slide rail 310 extending outward from below the inkjet unit 400. A tray 210 is movably connected to the slide rail 310, allowing the tray 210 to move directly below or away from the inkjet unit 400 with the assistance of the slide rail 310. The slide rail 310 facilitates moving the first positioning mechanism 200 directly below the inkjet unit 400 for printing, and also facilitates moving the first positioning mechanism 200 away from the inkjet unit 400 to easily remove the printed circuit board.
