[0002] The pressing and welding of multi-layer circuit boards is one of the basic structures of printed circuit boards. In the pressing manufacturing process, the drilling accuracy of the alignment holes between the board layers will directly determine the accuracy of the subsequent drilling and molding manufacturing processes, which will also affect the quality of the printed circuit board after molding.

[0003] According to a pre-alignment plate throwing device of a target drilling machine disclosed in Chinese utility model patent CN214315760U, an identification mechanism can be set up to intelligently scan the plate throwing position in advance and project the position frame through rays before the plate throwing robot arm works, so as to achieve the effect of pre-alignment and improve accuracy. This device also needs to use the plate throwing robot arm to throw the plate after pre-alignment. However, after the plate throwing robot arm absorbs and fixes the material plate through the suction plate, when moving the material plate to the pre-alignment position, there is no structure for placing a deceleration between the driving mechanism of the plate throwing robot arm and the suction plate, so that the material plate will be squeezed during the alignment placement, which may cause the material plate to move slightly.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: a pre-alignment plate throwing device of a target drilling machine, comprising a target drilling machine workbench 1 and an outer shell frame 2, a pre-alignment scanner 3 is fixed to one side of the inner wall of the outer shell frame 2, a plate throwing mechanical arm 4 is arranged on the side of the target drilling machine workbench 1, the end of the plate throwing mechanical arm 4 is connected to a liftable driving mechanism 5, a suction plate 6 is arranged at the bottom end of the driving mechanism 5, a power line 7 is connected to the surface of the plate throwing mechanical arm 4, a plate throwing mitigation mechanism is arranged between the suction plate 6 and the driving mechanism 5, a line fixing mechanism is arranged on the surface of the plate throwing mechanical arm 4, and the plate throwing mitigation mechanism comprises: a connecting component, which is arranged at the connection between the suction plate 6 and the driving mechanism 5; a mitigation component, which is arranged inside the connecting component; and a slidable fixing component, which is arranged on the side of the connecting component.

[0020] In this embodiment, preferably, the connecting assembly includes a connecting seat 100 symmetrically fixed at the bottom corner of the driving mechanism 5 and a connecting groove 101 opened at the bottom end of the connecting seat 100, and a connecting rod 102 adapted to the connecting groove 101 is symmetrically fixed at the top corner of the suction plate 6. The connecting rod 102 is slidably connected to the connecting groove 101. After the suction plate 6 is fitted with the drilling machine workbench 1, even if the driving mechanism 5 continues to descend, the connecting seat 100 can press down on the surface of the connecting rod 102 through the connecting groove 101 to relieve the pressure.

[0021] In this embodiment, preferably, the deceleration component includes a built-in groove 200 opened inside the connecting groove 101 and a groove 201 opened at the top of the connecting rod 102. The interior of the connecting groove 101 is provided with a deceleration spring 202 whose two ends are respectively embedded in the built-in groove 200 and the groove 201. Through the opening of the built-in groove 200 and the groove 201, the deceleration spring 202 can be stably squeezed inside the connecting groove 101 to deform or return to its original state.

[0022] In this embodiment, preferably, the slidable fixing component includes a slide groove 300 symmetrically opened on both sides of the connecting rod 102 and a screw hole 301 symmetrically opened on both sides of the inner wall of the connecting seat 100. Both sides of the connecting seat 100 are respectively provided with a fixing screw 302 screwed and connected with the screw hole 301, and the end of the fixing screw 302 is embedded in the inside of the slide groove 300, so that after assembly, when the connecting rod 102 moves inside the connecting groove 101, it plays a role in guiding and limiting the sliding range. At the same time, when it is necessary to disassemble the suction plate 6 and the driving mechanism 5 or replace the deceleration spring 202 inside the connecting groove 101, it can be screwed The fixing screw 302 is moved so that its end is withdrawn from the inside of the slide groove 300 and screwed into the inside of the screw hole 301, so that the limit between the connecting rod 102 and the connecting seat 100 can be quickly released, so that the suction plate 6 and the driving mechanism 5 can be disassembled or the deceleration spring 202 in the connecting groove 101 can be replaced. During assembly, it is only necessary to first insert the deceleration spring 202 into the inside of the connecting groove 101, and then embed the connecting rod 102 into the inside of the connecting groove 101, and then tighten the fixing screw 302 so that the end of it is screwed out from the inside of the screw hole 301 and embedded in the slide groove 300, and the limit assembly work can be completed.

[0023] In this embodiment, preferably, the wire fixing mechanism includes an L-shaped wire fixing device 400 fixed at equal distances on the surface of the board throwing robot arm 4 and a rubber buckle 401 fixed on the inner side of the L-shaped wire fixing device 400. The power cord 7 is connected to the L-shaped wire fixing device 400 by snapping, so that the power cord 7 can be limited and stored.

[0024] In this embodiment, preferably, the rubber buckle 401 is made of elastic material, so that when the power cord 7 is embedded in the inner side of the wire holder 400 , the rubber buckle 401 can be squeezed and deformed.

[0025] The working principle and use process of the utility model are as follows: when the material plate that has been pre-positioned is dropped, the suction plate 6 at the end is first controlled by the plate throwing mechanical arm 4 to suck up the material plate, and then the plate throwing mechanical arm 4 moves the material plate to align with the pre-aligned projection frame, and then the driving mechanism 5 is extended, which can drive the suction plate 6 to descend and get closer to the surface of the drilling machine workbench 1, and at the same time make the material plate and the pre-aligned projection frame accurately fit together. When the two are fitted together, the driving mechanism 5 is still extending, which will drive the connecting seat 100 to press down the internal deceleration spring 202 through the connecting groove 101 to slide on the surface of the connecting rod 102, and at the same time drive the fixed screw 302 to slide inside the slide groove 300 to play a moving guiding role, which can play a certain deceleration role, and will not generate pressure on the material plate adsorbed by the bottom of the suction plate 6, so as to avoid the displacement of the suction plate 6 when the material plate is separated, resulting in inaccurate alignment and unloading. After the material is completed, the driving mechanism 5 retracts into the end of the plate-casting mechanical arm 4, and drives the suction plate 6 to separate from the material plate. At this time, the two ends of the deceleration spring 202 inside the connecting groove 101 are reset to push the built-in groove 200 and the groove 201 respectively, so that the part of the connecting rod 102 retracted into the connecting groove 101 can be popped out, and at the same time, the fixing screw 302 is driven to slide inside the slide groove 300. When the fixing screw 302 slides to the internal top of the slide groove 300, the moving position of the connecting rod 102 can be limited, and the reset work between the suction plate 6 and the driving mechanism 5 is completed. When it is necessary to limit the power cord 7 on the surface of the plate-casting mechanical arm 4, the power cord 7 is first embedded into the inside from the side opening of the L-shaped wire fixer 400, and the rubber buckle 401 is squeezed to deform. When the power cord 7 is stuck in the inner side of the L-shaped wire fixer 400, the rubber buckle 401 is reset and popped up to limit the power cord 7.
