DETAILED DESCRIPTION

[0024] The embodiment of the present application discloses a multi-layer circuit board pressing device. Through the setting of the alignment structure 2, under the drive of the gear group 3, the gear rack group 4 and the linkage structure 5, the alignment structure 2 can move along the sliding groove 101, so that the edge guide wheel 205 can roll along the edge of the multi-layer circuit board 10 to be pressed and align the multi-layer circuit board 10 to be pressed, thereby improving the pressing quality and processing efficiency of the multi-layer circuit board 10 to be pressed, and by adjusting the screw 203, the position of the wheel rack 204 is changed, thereby adapting to multi-layer circuit boards 10 to be pressed of different sizes, and having a wider range of practical applications.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Example 1: Reference Figure 1 and Figure 3 The multi-layer circuit board pressing device disclosed in the embodiment of the present application includes an alignment structure 2, which is arranged at the top of the pressing calibration platform 1. The alignment structure 2 is provided with four groups. The alignment structure 2 is moved by a gear group 3, a gear rack group 4 and a linkage structure 5. The alignment structure 2 is used to align the multi-layer circuit board 10 to be pressed. The alignment structure 2 includes a sliding seat 201. A screw sleeve 202 is slidingly provided on the top of the sliding seat 201. A screw rod 203 is threadedly connected to the inner side of one end of the screw sleeve 202. The screw rod 203 passes through and is rotatably provided on one side of the sliding seat 201. A wheel frame 204 is fixedly provided on the other end of the screw sleeve 202. An edge guide wheel 205 is rotatably provided on one side of the bottom end of the wheel frame 204.

[0027] When the alignment structure 2 moves, the edge guide wheel 205 in the alignment structure 2 will contact the multi-layer circuit board 10 to be pressed, and the four edge guide wheels 205 will move synchronously from the edge of the multi-layer circuit board 10 to be pressed, thereby aligning multiple circuit boards in the multi-layer circuit board 10 to be pressed, and at the same time aligning the multi-layer circuit board 10 to be pressed to the center position above the pressing calibration table 1, thereby achieving the effect of positioning and aligning the multi-layer circuit board 10 to be pressed, and improving the pressing quality of the multi-layer circuit board 10 to be pressed.

[0028] Furthermore, when it is necessary to align and position multi-layer circuit boards 10 to be pressed together of different sizes, such as rectangles of different lengths and widths, it is sufficient to adjust the two relatively arranged alignment structures 2. During adjustment, the screw rod 203 is rotated so that the screw sleeve 202 can move along the sliding seat 201, and the relatively arranged wheel frame 204 will move away from or closer, thereby aligning and positioning multi-layer circuit boards 10 to be pressed together of different sizes, which is highly practical.

[0029] Furthermore, four sliding slots 101 and a push rod hole 102 are provided on the top of the pressing calibration platform 1 , and the sliding seat 201 is slidably arranged on the inner side of the sliding slots 101 , and the sliding slots 101 are inclined.

[0030] The sliding slot 101 is tilted so that the alignment structure 2 can also move along this track, and the tilted multi-layer circuit boards 10 to be pressed can be gradually aligned without affecting the placement of new multi-layer circuit boards 10 to be pressed.

[0031] See Figure 2 and Figure 4 The gear set 3 includes an active drive gear 301, a first driven gear 302 and a second driven gear 303. The active drive gear 301, the first driven gear 302 and the second driven gear 303 are coaxially connected. The second driven gear 303 is rotatably arranged at the bottom end of the pressing calibration platform 1. The gear rack set 4 includes a push-pull gear plate 401, a first shift gear rack 402 and a second shift gear rack 403. The push-pull gear plate 401 is meshed and arranged on the outer side of the active drive gear 301. The first shift gear rack 402 is symmetrically meshed and arranged on the first shift gear rack On the outside of the driven gear 302, the second linked shift gear rack 403 is symmetrically meshed and arranged on the outside of the second driven gear 303. The tops of the first linked shift gear rack 402 and the second linked shift gear rack 403 are both provided with guide grooves 4033. The inner sides of the guide grooves 4033 are both slidably provided with hanging fixed plates 404. The other side of the push-pull tooth plate 401 is slidably provided with a hanging plate rack 4011. The hanging plate rack 4011 and the hanging fixed plate 404 are fixedly provided at the bottom end of the pressing calibration table 1, and a handle is fixedly provided at the end of the push-pull tooth plate 401.

[0032] The push-pull gear plate 401 is moved by the handle, and the handle is pulled to make the push-pull gear plate 401 drive the active drive gear 301 in the gear set 3 to rotate, and the first driven gear 302 and the second driven gear 303 coaxially arranged with the active drive gear 301 will move together, and the first and second linked shift gear racks 402 and 403 symmetrically arranged on the outsides of the first and second driven gears 302 and 303 will move synchronously, thereby driving the linked shift structure 5 to drive the alignment structure 2 to move.

[0033] Among them, each first linked shift gear rack 402 and second linked shift gear rack 403 are connected to the sliding seat 201 through a linked shift structure 5, and the linked shift structure 5 is provided with four groups. The ends of the first linked shift gear rack 402 and the second linked shift gear rack 403 are fixedly provided with an extension plate 4031, and the top of the extension plate 4031 is fixedly provided with a guide slide column 4032, and the guide slide column 4032 is slidably provided on the inner side of the column inner slide groove 5011.

[0034] The function of the coupling structure 5 is mainly to transfer the linear movement driving force generated by the first coupling gear rack 402 and the second coupling gear rack 403 to the alignment structure 2 for use.

[0035] Furthermore, the linkage structure 5 includes a push-pull guide rod 501, and a column inner slide groove 5011 is opened on the outer side of the push-pull guide rod 501. One end of the push-pull guide rod 501 is rotatably provided with a connecting seat 502, and the connecting seat 502 is rotatably provided at the bottom end of the sliding seat 201. The other side of the connecting seat 502 is rotatably provided with a return spring 503, and the other end of the return spring 503 is rotatably provided with a fixed connecting seat 504, and the fixed connecting seat 504 is fixedly provided at the bottom end of the pressing calibration platform 1.

[0036] When performing alignment work, the movement of the second shifting gear frame 403 drives the push-pull guide rod 501 to tilt. Through the change of the push-pull guide rod 501, the connecting seat 502 can be moved, and when the connecting seat 502 is away from the fixed connecting seat 504, the return spring 503 is in an extended state, and the movement of the connecting seat 502 drives the alignment structure 2 to move, thereby performing positioning and alignment work.

[0037] After the alignment work is completed, the return force of the return spring 503 allows the alignment structure 2 to return to its original position, and the movement of the first shift gear rack 402 is consistent with that of the second shift gear rack 403. Taking the second shift gear rack 403 as an example, the movement of the second shift gear rack 403 at this time gradually approaches one side of the pressing calibration platform 1, and allows the guide slide column 4032 to slide on the inner side of the slide groove 5011 in the column, and the push-pull guide rod 501 gradually tilts and pulls the connecting seat 502 to move. The distance between the connecting seat 502 and the fixed connecting seat 504 becomes longer, and the return spring 503 is in an extended state, so that the connecting seat 502 will drive the alignment structure 2 to move.

[0038] See Figure 1 and Figure 2 A fixed support frame 7 is slidingly provided at the bottom end of the pressing and calibration platform 1, and a pressing device 8 is provided on the upper side of the fixed support frame 7. A first hydraulic rod 801 is fixedly provided on the top of the pressing device 8, and a guide fixed stand 802 is slidingly provided on the outer side of the pressing device 8. The guide fixed stand 802 is fixedly provided on the outer side of the fixed support frame 7. The first hydraulic rod 801 is externally connected to a hydraulic cylinder. A second hydraulic rod 9 is fixedly provided on one side of the pressing and calibration platform 1. The second hydraulic rod 9 is fixedly provided on one side of the fixed support frame 7, and the second hydraulic rod 9 is externally connected to a hydraulic cylinder.

[0039] Among them, the pressing equipment 8 can press the positioned and aligned multi-layer circuit board 10 to be pressed, and the first hydraulic rod 801 obtains driving force through an external hydraulic cylinder so that the pressing equipment 8 can be raised and lowered, and the second hydraulic rod 9 can obtain driving force through an external hydraulic cylinder to drive the pressing calibration table 1 to move.

[0040] Example 2: Reference Figure 1 、 Figure 2and Figure 7 , also includes a top plate assembly 6, the top plate assembly 6 is arranged at the bottom end of the pressing and calibration table 1, the top plate assembly 6 includes a fixed guide frame 601 and a connecting base plate 603, the fixed guide frame 601 is symmetrically fixedly arranged at the bottom end of the fixed support frame 7, and the top four corners of the connecting base plate 603 are fixedly provided with a lifting short rod 604, the outer side of the lifting short rod 604 is provided with a step, and the top of the step is fixedly provided with a return spring 605, and the return spring 605 is fixedly provided at the bottom end of the pressing and calibration table 1, and the other end of the lifting short rod 604 is fixedly provided with a touch plate top block 606, and the bottom end of the connecting base plate 603 is symmetrically fixedly provided with a touch lifting block 602, the bottom end of the touch lifting block 602 is set as an inclined surface, and the touch plate top block 606 is set for silicone rubber material, and the lifting short rod 604 is slidably provided on the inner side of the top rod hole 102.

[0041] The multi-layer circuit board 10 to be pressed, which is formed by multiple single-layer circuit boards, is placed on the top of the touch plate top block 606 when it is placed in the water, and does not contact the pressing calibration platform 1, which is convenient for positioning and aligning the multi-layer circuit board 10 to be pressed. The touch plate top block 606 is made of silicone rubber to prevent the high temperature of the multi-layer circuit board 10 to be pressed from damaging the touch plate top block 606 after pressing, and to prevent the touch plate top block 606 from damaging the bottom of the multi-layer circuit board 10 to be pressed. When the pressing calibration platform 1 moves, the fixed guide frame 601 leaves the contact top block 602, so that the lifting short rod 604 and the touch plate top block 606 descend, and the multi-layer circuit board 10 to be pressed will contact the pressing calibration platform 1. The top of the pressing plate is in contact with the top of the pressing plate, which is convenient for pressing. When the pressing work is completed, the pressing calibration table 1 is driven to move back by the second hydraulic rod 9. When the fixed guide frame 601 contacts the touch lifting block 602, the touch lifting block 602 is lifted. At the same time, the connecting base plate 603, the lifting short rod 604 and the touch plate top block 606 will all be lifted, and the multi-layer circuit board 10 to be pressed will be lifted up, which is convenient for the staff to remove the multi-layer circuit board 10 to be pressed after pressing. At this time, the reset spring 605 is in an extended state. After the fixed guide frame 601 is separated from the touch lifting block 602, the return force of the reset spring 605 makes the touch plate top block 606 return to its original position.

[0042] Working principle: Single circuit boards are placed on the top of the lamination calibration table 1 in sequence to form a multi-layer circuit board 10 to be laminated. At this time, the push-pull tooth plate 401 is moved by the handle. Pulling the handle can cause the push-pull tooth plate 401 to drive the active drive gear 301 in the gear set 3 to rotate, and the first driven gear 302 and the second driven gear 303 coaxially arranged with the active drive gear 301 will move together, and the first and second linked shifting gear racks 402 and 403 symmetrically arranged on the outside of the first and second driven gears 302 and 303 will move synchronously, thereby driving the linked shifting structure 5 to drive the alignment structure 2 to move; Among them, the function of the coupling structure 5 is mainly to transfer the linear movement driving force generated by the first coupling gear rack 402 and the second coupling gear rack 403 to the alignment structure 2, and after the alignment work is completed, the alignment structure 2 can return to its original position. The movement mode of the first coupling gear rack 402 is consistent with that of the second coupling gear rack 403. Taking the second coupling gear rack 403 as an example, the movement of the second coupling gear rack 403 at this time gradually approaches one side of the pressing calibration platform 1, and enables the guide slide column 4032 to slide on the inner side of the slide groove 5011 in the column, and the push-pull guide rod 501 gradually tilts and pulls the connecting seat 502 to move. The distance between the connecting seat 502 and the fixed connecting seat 504 becomes longer, and the return spring 503 is in an extended state, so that the connecting seat 502 will drive the alignment structure 2 to move; It should be noted that the sliding slot 101 is inclined, so the sliding slot 101 has a distal end and a proximal end. The starting point of the alignment structure 2 is the distal end, that is, far away from the multi-layer circuit board 10 to be laminated, and the end point is the proximal end, that is, close to the multi-layer circuit board 10 to be laminated. When the alignment structure 2 slides along the sliding slot 101, it gradually moves from the starting point to the end point, and the edge guide wheel 205 in the alignment structure 2 will contact the multi-layer circuit board 10 to be laminated. The four edge guide wheels 205 move synchronously from the edge of the multi-layer circuit board 10 to be laminated, thereby aligning multiple circuit boards in the multi-layer circuit board 10 to be laminated, and at the same time aligning the multi-layer circuit board 10 to be laminated to the center position above the lamination calibration table 1, thereby achieving the effect of positioning and aligning the multi-layer circuit board 10 to be laminated, thereby improving the lamination quality of the multi-layer circuit board 10 to be laminated; When it is necessary to align and position multi-layer circuit boards 10 to be pressed together of different sizes, such as rectangles of different lengths and widths, it is sufficient to adjust the two relatively arranged alignment structures 2. During adjustment, the screw rod 203 is rotated so that the screw sleeve 202 can move along the sliding seat 201, and the relatively arranged wheel frame 204 will move away from or closer to each other, thereby being able to align and position multi-layer circuit boards 10 to be pressed together of different sizes, with strong practicality. Since the pressing and aligning stage 1 is located on the top side of the fixed support frame 7 during the positioning and alignment work, the multi-layer circuit board 10 to be pressed is placed on the top of the touch-plate top block 606 in the top plate assembly 6, and the touch-plate top block 606 is made of silicone rubber to prevent the high temperature of the multi-layer circuit board 10 to be pressed from damaging the touch-plate top block 606 after pressing, and to prevent the touch-plate top block 606 from damaging the bottom of the multi-layer circuit board 10 to be pressed. When the pressing and aligning stage 1 moves, the fixed guide frame 601 leaves the touch-lifting block 602, so that the lifting short rod 604 and the touch-plate top block 606 descend, and the multi-layer circuit board 10 to be pressed will be in contact with the top of the pressing and aligning stage 1, which is convenient for pressing. When the pressing work is completed, the pressing calibration table 1 is driven to move back by the second hydraulic rod 9. When the fixed guide frame 601 contacts the touch lifting block 602, the touch lifting block 602 is lifted. At the same time, the connecting base plate 603, the lifting short rod 604 and the touch plate top block 606 will all be lifted, and the multi-layer circuit board 10 to be pressed will be lifted up, so that the staff can remove the multi-layer circuit board 10 to be pressed after pressing. At this time, the reset spring 605 is in an extended state. After the fixed guide frame 601 is separated from the touch lifting block 602, the return force of the reset spring 605 causes the touch plate top block 606 to return to its original position.

Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
