At the same time, when drying, since the fixing jig body 5 is in a vertical state, the drying air flow thereof will not be adversely affected by the shaking of the fixing jig body 5, ensuring the flow effect of the internal drying air flow, and thus improving the drying efficiency of the device.

[0035] Example 2 further optimizes the sheet material ink drying device provided in Example 1. Specifically, as Figure 1 、 Figure 3 and Figure 11 shown, two mounting shafts 12 are arranged on each of the two guide rails 3. Transmission wheels 13 are fixedly connected to the outer walls of the four mounting shafts 12. A driving chain 11 is arranged on the outer walls of the two transmission wheels 13 on the same side.

[0037] Embodiment 3 further optimizes the plate ink drying device provided in Embodiment 1 or 2.

[0038] Further, as Figures 8 - 10 shown, the plate edge clamping module 7 further includes: A plurality of air pump bodies 702 are respectively arranged on a plurality of fixed socket seats 701. One end of each of the plurality of air pump bodies 702 is provided with a connecting pipe 711, and one end of each of the plurality of connecting pipes 711 is fixedly connected with a communication cavity 712; A plurality of telescopic air sleeves 704, and every two telescopic air sleeves 704 are arranged on the same fixed socket seat 701.

The telescopic air sleeve 704 and the multi-stage telescopic rod 703 are used to adjust the height; A plurality of conveying pipes 707, one end of each of the plurality of conveying pipes 707 is respectively communicated with the inside of the plurality of telescopic air sleeves 704, and the other end of every two conveying pipes 707 is communicated with the inside of the same communication cavity 712 (the air pump body 702 can adjust the telescopic degree of the telescopic air sleeve 704 through the conveying pipe 707, the connecting pipe 711 and the communication cavity 712).

[0039] Further, as Figures 8 - 10 shown, the plate edge clamping module 7 further includes: A plurality of adjusting ring seats 705, the adjusting ring seats 705 are fixedly connected to one end of two adjacent telescopic air sleeves 704, and two mounting disc seats 714 are fixedly connected to each of the plurality of adjusting ring seats 705; A plurality of hollow pipe sleeves 717, the plurality of hollow pipe sleeves 717 are respectively arranged on one outer wall of the plurality of mounting disc seats 714, and one end of every two hollow pipe sleeves 717 is fixedly connected to the same plate edge clamp two 713.

[0040] Further, as Figures 8 - 10 shown, the plate edge clamping module 7 further includes: A plurality of clamp rods 715, the clamp rods 715 are arranged on two adjacent mounting disc seats 714, and one outer wall of each of the plurality of clamp rods 715 is provided with a plate edge clamp one 706, and the plate edge clamp one 706 and the plate edge clamp two 713 are arranged at a 90-degree angle; A plurality of clamping motors 716, the plurality of clamping motors 716 are arranged on one outer wall of some of the plurality of mounting disc seats 714, and the output shafts of the plurality of clamping motors 716 are respectively connected to one end of the plurality of clamp rods 715 through couplings (the clamping motor 716 can drive the clamp rod 715 and the plate edge clamp one 706 to rotate, so that the plate edge clamp one 706 and the plate edge clamp two 713 clamp the single edge of the PCB substrate that is not fixed).

[0041] When the length dimension of the PCB substrate is insufficient, the fixed fixture body 5 usually fixes and clamps at most three sides of it. At this time, during the drying operation, the single edge of the PCB substrate that is not fixed will be deformed. The plate edge clamping module 7 can clamp the edge of the PCB substrate during use, that is, clamp the single edge of the PCB substrate that is not fixed by the fixed fixture body 5, so as to avoid the deformation of the unclamped edge during the drying operation, thereby improving the drying effect and quality of the PCB substrate and avoiding adverse effects on subsequent processing operations.

[0042] The use process of the sheet material ink drying device provided by the present invention is as follows: During use, the fixed fixture body 5 is arranged on the fixture seat 9. At this time, starting the driving motor 2 can drive the mounting shaft rod 12 and the transmission wheel 13 to rotate, and then drive the driving chain 11 and the fixture seat 9 to move through the transmission wheel 13, so as to convey the fixed fixture body 5 for drying movement; During drying, as the fixed fixture body 5 moves, the servo motor 405 runs, the servo motor 405 drives the mounting rod 406 to rotate, and further drives the linkage wheel 407 and the linkage chain 409 to run, so that the linkage chain 409 drives the follower bracket 402 to move. At this time, the follower bracket 402 is located on one side of the fixed fixture body 5; When the fixed fixture body 5 contacts the buffer backing plate 408, the buffer torsion spring 415 and the damping spring are stressed. At this time, the buffer torsion spring 415 absorbs and buffers the vibration energy through its own elastic deformation, and cooperates with the damping spring to further buffer the fixed fixture body 5 so that it quickly enters a stable vertical state after contact; After the fixed fixture body 5 is initially stabilized, the universal motor 413 operates. The universal motor 413 can drive the winding wheel 419 to rotate, thereby enabling the winding wheel 419 to tighten the connecting cable 414. As the connecting cable 414 is tightened, the telescopic spring 416 is compressed, and then the lifting base 411 moves inside the mounting socket 410 to adjust the position of the stable hanging plate 401 through the lifting base 411. At this time, as the stable hanging plate 401 moves, it will gradually be hooked to the fixed fixture body 5 and apply a certain downward pulling force to it, so that the fixed fixture is in a vertical state during the subsequent drying movement; When the fixed fixture body 5 is in a vertical state, the stepping motor 709 operates and drives the driving gear 710 to rotate. Since the driving gear 710 meshes with the toothed ring part 708, it can drive the fixed socket 701 to rotate, so that the fixed socket 701 drives the telescopic air sleeve 704 and the adjusting ring seat 705 to be in a vertical state. At this time, the air pump body 702 operates, and the air pump body 702 conveys gas through the connecting pipe 711 into the communication cavity 712, and further conveys it into the telescopic air sleeve 704 through the conveying pipe 707, causing the telescopic air sleeve 704 to expand, and cooperating with the multi-stage telescopic rod 703 to raise the adjusting ring seat 705 until the adjusting ring seat 705 drives the edge fixture one 706 and the edge fixture two 713 to move to the single-edge part of the PCB substrate that is not fixed; When the unfixed edge is fixed, one side of the PCB substrate contacts one side of the edge fixture two 713. At this time, the clamping motor 716 operates, drives the fixture rod 715 to rotate through the clamping motor 716, and further drives the edge fixture one 706 to rotate, causing it to rotate 90 degrees, and then contact the other side of the PCB substrate, thereby completing the fixation of its unfixed edge until the drying is completed.
