[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0022] like Figure 1-Figure 4 As shown, it relates to a vehicle-mounted ultra-thick copper circuit board printing device, including a base 1, an L-shaped support plate 2 is fixedly connected to one side of the upper surface of the base 1, a cylinder 3 is fixedly connected to the top of the L-shaped support plate 2, a mounting sleeve 4 is fixedly connected to the telescopic end at the bottom of the cylinder 3 and the upper surface of the base 1, the two mounting sleeves 4 are symmetrically arranged, and the adjacent sides of the two mounting sleeves 4 are open, and the open sides of the two mounting sleeves 4 are clamped with plug blocks 5, the adjacent sides of the two plug blocks 5 are respectively fixedly connected with a support plate 7 and a hot pressing plate 8, and the hot pressing plate 8 is located above the support plate 7, a fixing component 6 is provided on the side wall of the plug block 5, an annular cutter 9 is fixed to the outer wall of the hot pressing plate 8, through holes 81 are opened on both sides of the hot pressing plate 8, and a pushing component 11 is provided inside the through hole 81, a controller 12 is installed on one side of the upper surface of the base 1, and the hot pressing plate 8 is electrically connected to the controller 12 through a wire.

[0023] like Figure 1-Figure 2 As shown, a plurality of positioning posts 10 for passing through positioning holes of the circuit board are fixed on the upper surface of the supporting plate 7 .

[0024] When placing the circuit board substrate on the upper surface of the supporting plate 7 , the circuit board substrate can be positioned by inserting the positioning posts 10 into the substrate positioning holes, so that the circuit board substrate and the supporting plate 7 completely overlap.

[0025] like Figure 1-Figure 3As shown, a latch hole 41 is provided on one side of the mounting sleeve 4 near the fixing component 6, and the fixing component 6 includes a groove 61 provided on the side wall of the plug block 5, a first spring 62 is fixedly connected to the inner wall of the groove 61, a slide plate 64 is fixedly connected to the other end of the first spring 62, a latch tooth 65 is fixedly connected to the other side of the slide plate 64, an opening 63 is provided on one end of the groove 61 near the latch hole 41, and the latch tooth 65 passes through the opening 63 and is latched into the latch hole 41.

[0026] When the plug block 5 is inserted into the installation sleeve 4, the first spring 62 pushes the latch 65 into the latch hole 41, thereby realizing the fixed connection between the plug block 5 and the installation sleeve 4. This connection method allows the support plate 7 to be quickly fixed on the surface of the base 1, and the hot pressing plate 8 to be quickly fixed on the telescopic end at the bottom of the cylinder 3. When the support plate 7 and the hot pressing plate 8 need to be disassembled and replaced, the latch 65 can be pressed to retract into the groove 61, so that the latch 65 is disengaged from the latch hole 41, and then the plug block 5 can be pulled out from the installation sleeve 4, thereby realizing the disassembly of the support plate 7 and the hot pressing plate 8.

[0027] like Figure 3 As shown, the size of the slide plate 64 is larger than the size of the opening 63. When the first spring 62 pushes the slide plate 64 and the latching teeth 65 out of the groove 61, the opening 63 can prevent the slide plate 64 from being separated from the groove 61.

[0028] like Figure 1-Figure 2 As shown, the size of the support plate 7 is the same as the size of the circuit board substrate, and the inner wall of the annular cutter 9 is in contact with the outer wall of the support plate 7.

[0029] When the hot pressing plate 8 and the annular cutter 9 descend, the annular cutter 9 can just cut off the excess copper foil on the side of the circuit board substrate.

[0031] When the hot pressing plate 8 is put on, the second spring 113 will pull the penetration rod 111 downward, so that the penetration rod 111 can press the circuit board substrate against the surface of the supporting plate 7 to prevent the circuit board substrate from being stuck inside the annular cutter 9.

[0032] Working principle: put the circuit board substrate on the surface of the support plate 7, then spread the copper foil on the surface of the circuit board substrate, then start the cylinder 3 to drive the hot press plate 8 and the annular cutter 9 to descend, the hot press plate 8 will press the copper foil on the surface of the circuit board substrate, and during the descent of the hot press plate 8, the bottom end of the penetration rod 111 will first contact the copper foil on the surface of the circuit board substrate, when the hot press plate 8 fits the copper foil on the surface of the circuit board substrate, the second spring 113 is in a stretched state, and the annular cutter 9 just cuts off the excess copper foil on the side of the circuit board substrate, after the hot pressing is completed, the cylinder 3 drives the hot press plate 8 and the annular cutter 9 to rise and reset, the second spring 113 shortens and resets, and it will pull the penetration rod 111 to squeeze the circuit board substrate to prevent the circuit board substrate from being stuck inside the annular cutter 9. When processing circuit board substrates of different sizes, the support plate 7 can be removed from the surface of the base 1, and the hot press plate 8 can be removed from the telescopic end at the bottom of the cylinder 3 and then replaced.
