DETAILED DESCRIPTION
[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings.
[0024] A multi-layer circuit board auxiliary production device, such as Figure 1As shown, it includes a body 1 for supporting the whole, a cylinder 2 is provided on the upper part of the body 1, and a hot pressing plate 3 is fixedly connected to the bottom of the telescopic rod of the cylinder 2. The hot pressing plate 3 adopts a hot pressing method, which is a prior art and will not be elaborated in this embodiment. A storage table 4 is provided on the side of the body 1 away from the cylinder 2. People can stack multiple layers of conductive patterns and insulating material layers alternately and place them on the storage table 4. Then, the hot pressing plate 3 can be pressed down by controlling the telescopic rod of the cylinder 2. The hot pressing plate 3 can press the multiple layers of conductive patterns and insulating material layers. During the pressing process, the conductive patterns and insulating material layers will be pressed thin, and the excess material will overflow from the edge (usually in the form of sheets). The excess material on the edge needs to be cleaned up, so people usually put the pressed multi-layer circuit board into a cutting machine for cutting. Such processing is relatively troublesome, so this solution adopts a method of starting the cutting operation immediately after the pressing is completed, which is as follows:
[0025] like Figure 1 As shown, the electric slide rail 5 is arranged on the side of the machine body 1 close to the storage table 4, and a slider 6 is provided on the electric slide rail 5. The slider 6 and the electric slide rail 5 are slidably connected, and a cutter 7 is provided on the slider 6. After the hot pressing plate 3 is pressed down, the electric slide rail 5 and the cutter 7 start to work, and the electric slide rail 5 controls the slider 6 to move left, and the slider 6 moves left to drive the cutter 7 to move left, and the cutter 7 can cut off the remaining material. After the cutting is completed, the telescopic rod of the cylinder 2 drives the hot pressing plate 3 to move up, and the electric slide rail 5 controls the slider 6 and the cutter 7 to move right and reset.
[0026] Since the multi-layer circuit board is laminated using hot pressing, under the conditions of hot pressing, the multi-layer conductive patterns and insulating material layers will become soft and overflow from the edges. At this time, these overflowing residual materials have not yet completely solidified and therefore have a certain degree of stickiness. In this way, the residual materials may fall vertically onto the body 1 and adhere to the body 1. When the cutter 7 cuts the residual materials, the residual materials are easily adhered to the cutter 7, and there is a certain degree of difficulty in cutting.
[0027] To this end, in this embodiment, an air outlet member 701 is provided on the machine body 1. The air outlet of the air outlet member 701 faces upward, and the air inlet of the air outlet member 701 is connected to the external air inlet device. When the residual material is generated, the residual material is located directly above the air outlet member 701. Blowing air upward through the air outlet member 701 can achieve two beneficial effects:
[0028] First, the solidification effect: during the overflow of the residual material, the residual material can be cooled by the gas, which can accelerate the solidification of the residual material. In this way, when the cutter 7 cuts the residual material, it is more convenient and can also prevent the residual material from sticking to the cutter 7;
[0029] Second, the suspension support effect: by precisely adjusting the air pressure of the external air intake device, the gas is discharged evenly, thereby blowing up the residual material and keeping it in a straight state. This straight placement not only helps to improve the convenience of cutting, but also avoids the residual material from directly sticking to the body 1 through the suspension support.
[0030] After the remaining material is cut, it will float above the gas outlet piece 701. Since the remaining material has been in the hot pressing environment and is affected by the high temperature, it has not been completely solidified and is still in a soft state with a certain degree of stickiness. Therefore, in this embodiment, we use a winding method to clean the remaining material. The specific solution is as follows:
[0031] like Figure 1 and Figure 2 As shown, the mounting bracket 8 is fixedly connected to the bottom of the slider 6, and a rotating shaft 9 is provided on the side of the mounting bracket 8 away from the slider 6. The rotating shaft 9 and the mounting bracket 8 are rotatably connected. A collecting barrel 10 is provided on the rotating shaft 9, and the collecting barrel 10 is fixedly connected to the rotating shaft 9. The collecting barrel 10 moves left as the slider 6 moves left. When the outer wall of the collecting barrel 10 contacts the residual material, the residual material may stick to the outer wall of the collecting barrel 10 due to viscosity. Then, when the collecting barrel 10 continues to move left, the collecting barrel 10 can be automatically rotated by a power source. The rotation of the collecting barrel 10 can automatically roll up the residual material, thereby achieving the purpose of clearing the material.
[0032] like Figure 1 、 Figure 3 and Figure 6 As shown, the transmission component 11 is arranged on the rotating shaft 9, and a reduction gear box 12 is provided on the side of the transmission component 11 away from the rotating shaft 9. The output end of the reduction gear box 12 is connected to the transmission component 11, and the reduction gear box 12 is fixed on the slider 6. The input end of the reduction gear box 12 is connected to the output shaft of the cutter 7. The power source is the cutter 7. When the cutter 7 is working, the power will be transmitted to the rotating shaft 9 through the transmission component 11, so that the rotating shaft 9 drives the collecting barrel 10 to rotate.
[0033] Considering that the cutter 7 runs very fast when working, and the collecting drum 10 needs to rotate slowly when winding the remaining material to achieve the purpose of winding, the rotating shaft 9 does not require a high speed, so a reduction box 12 is provided to reduce the transmission speed to the required speed.
[0034] As explained above, the collecting drum 10 rewinds the residual material completely by the viscosity of the residual material. If the residual material is very weak due to the gas cooling, it will be very laborious to rewind and there may be a problem of being unable to rewind. Therefore, a cone head frame 13 is provided. Figure 4As shown, cone heads are evenly spaced on the cone head rack 13, and the cone heads can be quickly inserted into the residual material. The cone head rack 13 is set on the collecting drum 10, and the cone head rack 13 is evenly spaced along the outside of the collecting drum 10. In this way, when the collecting drum 10 rotates, the cone head rack 13 rotates accordingly to hook up the residual material and rewind it. By setting the cone head rack 13, the efficiency of the rewinding drum 10 in rewinding the residual material can be improved.
[0035] After the collecting drum 10 has rolled up the residual material, the residual material needs to be removed from the collecting drum 10. However, the arrangement of the cone head frame 13 makes it more difficult to remove the residual material. In this embodiment, the cone head frame 13 is placed inside the collecting drum 10 before the residual material is removed.
[0036] like Figure 2 As shown, a guide column 14 is provided on the cone head frame 13, and the guide column 14 and the cone head frame 13 are slidably connected. The guide column 14 is fixedly connected to the inside of the collecting tube 10, so that the cone head frame 13 can be received into the collecting tube 10 to remove the residual material. The cone head frame 13 is retracted by a rotating component.
[0037] In addition, in order to keep the cone head frame 13 in an outwardly extended state, a spring 15 is wound around the guide column 14. One end of the spring 15 is fixedly connected to the cone head frame 13, and the other end of the spring 15 is fixedly connected to the inside of the collecting tube 10. The elastic force of the spring 15 can keep the cone head frame 13 in an outwardly extended state.
[0038] like Figure 1 and Figure 4 As shown, the rotating assembly includes an L-shaped rod 16, which is arranged at both ends of the cone head frame 13. The cone head frame 13 and the L-shaped rod 16 are fixedly connected. A chute plate 17 is arranged between adjacent L-shaped rods 16. The chute plate 17 is rotatably connected to the rotating shaft 9. A plurality of chute plates equidistantly distributed along the circumferential direction are provided on the chute plate 17, and the chute and the L-shaped rod 16 are slidably connected.
[0039] If the cone head frame 13 needs to be retracted, the inclined slot disk 17 can be rotated counterclockwise, and the inclined slot disk 17 will drive the L-shaped rod 16 to approach the center of the inclined slot disk 17 through the inclined slot. Therefore, the L-shaped rod 16 will drive all the cone head frames 13 to retract into the collection tube 10, and when the inclined slot disk 17 is rotated clockwise, the cone head frame 13 will extend out of the collection tube 10. The power source of the inclined slot disk 17 comes from the gear 18, which is provided on the outside of the inclined slot disk 17. The gear 18 and the inclined slot disk 17 are fixedly connected. A rack 19 is provided on the side of the body 1 away from the slider 6, and the rack 19 is fixedly connected to the body 1.
[0040] like Figure 1 and Figure 5As shown, considering that the residual material is located on the left side of the body 1 after the collecting drum 10 is wound up, and then the residual material needs to be taken off from the collecting drum 10, the rack 19 is set on the left side of the body 1. After the collecting drum 10 is wound up, the gear 18 moves to the left until the rack 19 is engaged, and the gear 18 moves to the left and rotates counterclockwise due to the rack 19, thereby achieving the purpose of shrinking the cone head frame 13 into the inside of the collecting drum 10.
[0041] After the cone head frame 13 is retracted into the collecting tube 10, Figure 2 and Figure 7 As shown, in this embodiment, a scraper plate 20 is provided on the outside of the collecting barrel 10. The scraper plate 20 is sleeved on the outside of the collecting barrel 10. The inner diameter of the scraper plate 20 is equal to the outer diameter of the collecting barrel 10. Therefore, the inner side of the scraper plate 20 is in close contact with the collecting barrel 10, so the scraper plate 20 can be driven backward to push the residual material backward.
[0042] In order to facilitate the pushing of the scraper plate 20, as Figure 2 As shown, a pulling frame 21 is provided on the side of the scraping plate 20 close to the mounting frame 8. The pulling frame 21 is fixedly connected to the scraping plate 20, and the pulling frame 21 is slidably connected to the mounting frame 8. People can push the scraping plate 20 to move by pulling the pulling frame 21.
[0043] When the residual material is wound, in order to prevent the residual material from falling off from the rear end of the collecting drum 10, Figure 2 As shown, a baffle plate 22 is provided on the side of the collecting cylinder 10 away from the scraping plate 20. The baffle plate 22 is sleeved on the outside of the collecting cylinder 10 to block the rear of the residual material. When the residual material is pushed out, the baffle plate 22 can be removed to facilitate pushing the material.
[0044] The stop plate 22 is blocked by a stop mechanism, and a stop ring 23 is fixedly connected to the outside of the collecting tube 10 near the side of the stop plate 22. The stop ring 23 is in contact with the stop plate 22. The function of the stop ring 23 is to prevent the stop plate 22 from moving forward too long when people install the stop plate 22 on the collecting tube 10, and to limit the position of the stop plate 22.
[0045] like Figure 2 and Figure 7 As shown, the blocking mechanism includes a wedge block 24, which is arranged on the stop plate 22. The wedge block 24 is in contact with the stop plate 22, and the wedge block 24 is used to stop the rear side of the stop plate 22. In this way, the cooperation between the wedge block 24 and the stop plate 22 can limit the stop plate 22 and can also stop the excess material. A wedge frame 25 is provided on the wedge block 24, and the wedge frame 25 and the wedge block 24 are slidably connected. A spring 26 is connected between the wedge block 24 and the wedge frame 25. An inclined surface is provided on the inner side of the stop plate 22, and the inclined surface and the wedge surface of the wedge block 24 are squeezed and fitted.
[0046] When installing the retaining plate 22, directly push the retaining plate 22 forward from the rear side of the wedge block 24. The inclined surface of the retaining plate 22 will contact the wedge surface of the wedge block 24 and drive the wedge block 24 to move closer to each other. The spring 26 is compressed. After the retaining plate 22 moves between the wedge block 24 and the retaining plate 22, the spring 26 drives the wedge block 24 to return to its original position and resist the retaining plate 22. When the retaining plate 22 needs to be removed, the wedge blocks 24 are driven to move closer to each other to release the retaining plate 22.
[0047] During the above operation, people need to manually drive the wedge block 24. In order to reduce manpower, this embodiment proposes the following solution:
[0048] The wedge frame 25 is rotatably connected to the collecting barrel 10. The side of the wedge frame 25 away from the wedge block 24 is a wedge surface. The extrusion ring 28 is arranged on the side of the scraper plate 20 away from the baffle plate 22. The extrusion ring 28 is provided with an inclined surface. The inclined surface and the wedge surface of the wedge block 24 are squeezed together. The extrusion ring 28 is driven to move backward by the backward movement of the scraper plate 20. After the inclined surface of the extrusion ring 28 and the wedge surface of the wedge block 24 are squeezed, the front of the wedge frame 25 is rotated outwards, and the wedge frame 25 is rotated outwards. 5 is rotated inwardly at the rear, thereby causing the automatic wedge blocks 24 to move closer to each other and release the stop plate 22. In this way, there is no need to manually drive the wedge blocks 24, which saves manpower. After the material is pushed, the scraper plate 20 moves forward to reset and drives the extrusion ring 28 to move forward to release the wedge frame 25. In order to enable the wedge frame 25 to return to its original state, a torsion spring 27 is provided between the wedge frame 25 and the inside of the collecting barrel 10. The torsion spring 27 maintains the wedge frame 25 in its initial state through elastic force.
[0049] After the reeled-in residual material is pushed backward, the residual material may become loose and fall, making it inconvenient to collect. Therefore, in this embodiment, a multi-stage telescopic rod 29 is fixedly connected to the side of the extrusion ring 28 away from the scraping plate 20, and the other end of the multi-stage telescopic rod 29 is fixedly connected to the scraping plate 20. By providing the multi-stage telescopic rod 29, the loosening and removal of the retaining plate 22 can be delayed. When the scraping plate 20 moves, the retaining plate 22 can cooperate with each other to squeeze the residual material into blocks for subsequent collection. The operating principle is as follows:
[0050] When the scraper plate 20 moves backward, the rear end of the multi-stage telescopic rod 29 is driven to extend backward. At this time, the extrusion ring 28 contacts the wedge frame 25, but cannot squeeze the wedge frame 25. Therefore, the abutment plate 22 remains in a state of resisting the residual material. Therefore, the scraper plate 20 will squeeze the residual material during the backward movement, making the loose residual material become tight. When the multi-stage telescopic rod 29 is extended to the limit, the front end of the multi-stage telescopic rod 29 will pull the extrusion ring 28 to move backward, and the extrusion ring 28 will squeeze the wedge frame 25, thereby achieving the purpose of loosening the abutment plate 22. In this way, the residual material has been squeezed into a block state, so that the purpose of first squeezing the residual material into blocks and then automatically pushing out the block residual material can be achieved. When the scraper plate 20 moves forward to reset, the multi-stage telescopic rod 29 will be retracted and reset. At the same time, when the wedge frame 25 rotates and resets, the extrusion ring 28 is pushed forward and reset by the wedge surface.
[0051] It should be noted that when the multi-stage telescopic rod 29 is extended to the limit, the scraper plate 20 is located at a quarter position behind the collecting cylinder 10, and the remaining material is pressed into blocks at a quarter position.
[0052] There will be a hole in the cone head frame 13 at the position where the collecting tube 10 is extended and retracted, and because of the cone head structure, when the cone head is retracted to the inside of the collecting tube 10, there will be a gap between the tip of the cone head and the collecting tube 10, so that the residual material on the collecting tube 10 may enter the inside of the collecting tube 10 through the gap, and the residual material stuck to the cone head cannot be scraped off. Therefore, an elastic ring 30 is provided on the cone head, and the elastic ring 30 is sleeved on the cone head of the cone head frame 13. The elastic ring 30 is fixedly connected to the collecting tube 10 at equal intervals. As the cone head is extended and retracted, the elastic ring 30 can adaptively shrink, so that the elastic ring 30 remains in a state of close contact with the cone head, and the residual material on the cone head can be scraped off. At the same time, the elastic ring 30 always fills the gap between the cone head and the collecting tube 10, which can prevent the residual material from entering the inside of the collecting tube 10 through the gap.
