Description

Technical Field

[0001] The present invention belongs to the technical field of the production and manufacturing of copper clad laminates, and particularly relates to an anti-misalignment device for stacking copper clad laminates and a hot press. Background Art

[0002] A copper clad laminate is a sheet material in which a layer of copper foil is covered on an insulating substrate through an adhesive, and is widely used in electronic devices as the basis of a circuit board. With the increase in circuit complexity and space limitations, multi-layer copper clad laminates are used to provide more circuit connections. Each layer of the copper clad laminate includes a conductive copper foil layer and an insulating layer that isolates different layers to prevent short circuits and interference. The lamination process is usually used to manufacture such a laminated structure, and after stacking each layer of copper foil and insulating material, they are tightly bonded through hot pressing or chemical reactions.

[0003] Currently, when stacking copper clad laminates, it is necessary to stack them one by one manually, and it is necessary to make the copper foil of the upper layer contact the insulating layer of the lower layer, that is, stack the plates in sequence. In this way, it is very easy for manual stacking to misplace the front and back sides of two adjacent copper clad laminates, resulting in the scrapping of the entire copper clad laminate.

[0004] In view of the above technical problems, the applicant has retrieved some prior arts to achieve the correct stacking order. For example, an anti-misalignment device for stacking copper clad laminates and a hot press with the patent publication number CN215590196U. Its main technical means is that when workers stack copper clad laminates one by one under the scanner, the scanner can scan the layer markings on the copper clad laminates and transmit the scanned stacking order information of the copper clad laminates to the computer. The computer receives the signal and gives an early warning for the signal of incorrect stacking. Workers can re-adjust the placement order to reduce the scrap rate of the copper clad laminates. After analysis by the applicant, the disadvantages of this technical solution are as follows: The above solution scans whether the stacking order of the stacked copper clad laminates is incorrect through the scanner. When the order is incorrect, workers need to re-adjust the placement order. This not only reduces the processing efficiency, but also because the flexible copper clad laminate is relatively soft, if it is manually flipped and adjusted in order, the flexible copper clad laminate may be subjected to a twisting force during the flipping process, resulting in the copper clad laminate being prone to deformation, and further leading to damage or direct scrapping of the copper clad laminate. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-misalignment device for stacking copper clad laminates and a hot press for the deficiencies of the prior art, so as to solve the technical problem that the copper clad laminate is prone to deformation and damage when the order is adjusted by manual flipping in the prior art.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] An anti-misalignment device for stacking copper clad laminates includes conveying rollers, and the device further includes:

[0008] Electric rods are installed on the inner walls of the two front ends of the conveying roller. The tops of the electric rods are flush with the top of the conveying roller. The electric rods are connected to an external power supply device, and the electric rods are also connected to a processor.

[0009] A front flap and a rear flap are installed in the middle section of the conveying roller. The front flap and the rear flap are hinged together. The center position of the rotation of the front flap and the rear flap is connected to a coaxial driving member through a rotating shaft. The coaxial driving member enables the front flap and the rear flap to rotate coaxially, and enables the front flap and the rear flap to rotate towards each other or away from each other. The processor is connected to the coaxial driving member.

[0010] As a preference of the above technical solution, a number of adsorption components I are installed on the surface of the front flap, and a number of adsorption components II are installed on the surface of the rear flap.

[0011] As a preference of the above technical solution, a number of support rods are arranged on both sides of the front flap and the rear flap.

[0012] As a preference of the above technical solution, U-shaped frames are installed at both ends of the rotating shaft, and telescopic members are installed at the bottoms of the U-shaped frames.

[0013] As a preference of the above technical solution, a number of guiding rings are sleeved through between the front flap and the rear flap. The guiding rings are coaxial with the rotating shaft. The guiding rings are fixed on the U-shaped frames through connecting rods. The front flap and the rear flap rotate around the guiding rings when rotating.

[0014] As a preference of the above technical solution, an outer guiding groove is opened outside the guiding ring, and an inner guiding groove is opened inside the guiding ring. A front pressing plate and a rear pressing plate are respectively slidably installed in the outer guiding groove. Through holes for the front pressing plate and the rear pressing plate to pass through are opened on the front flap and the rear flap respectively. A magnetic block I and a magnetic block II are respectively slidably installed in the inner guiding groove. The magnetic block I attracts the front pressing plate, and the magnetic block II attracts the rear pressing plate. The magnetic block I and the magnetic block II are respectively located at both ends of the inner guiding groove. Elastic members are connected between the magnetic block I and the magnetic block II and the ends of the inner guiding groove respectively. A front connecting pipe and a rear connecting pipe are respectively connected outside the guiding ring. The front connecting pipe is located at the position between the magnetic block I and the end of the inner guiding groove, and the rear connecting pipe is located at the position between the magnetic block II and the end of the inner guiding groove. The front connecting pipe is connected to the air outlet end of the adsorption component I, and the rear connecting pipe is connected to the air outlet end of the adsorption component II.

[0015] As a preference of the above technical solution, an electrostatic elimination mechanism is installed between the inner walls of the rear end of the conveying roller.

[0016] A hot press includes the above copper clad laminate stacking error prevention device and a hot press. A positioning frame is arranged on the hot press, and the positioning frame is located at the conveying end of the conveying roller.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, the contact surface between the copper clad laminate and the conveying roller is detected by the energized rod, and the copper clad laminate with the wrong bottom surface orientation is flipped by 180° through the front flip plate and the rear flip plate, so that the insulating layers of the copper clad laminates passing through the front flip plate and the rear flip plate are all in contact with the conveying roller. In this way, the sequence is not easy to go wrong during subsequent stacking, effectively avoiding the scrapping of the copper clad laminates caused by the wrong sequence of multi-layer copper clad laminates; at the same time, the copper clad laminate is flipped through the cooperation of the front flip plate and the rear flip plate. The front flip plate and the rear flip plate both have a supporting and protective effect on the copper clad laminate during the flipping process, effectively avoiding the copper clad laminate from being subjected to a torsional force during the flipping process, thus effectively avoiding the copper clad laminate from being deformed and damaged or directly scrapped;

[0019] 2. In the present invention, the copper clad laminate is sucked by the adsorption component I and the adsorption component II during the flipping process of the copper clad laminate. In this way, the copper clad laminate is not easy to displace or fall off from the front flip plate or the rear flip plate during the flipping process, thus ensuring the stability of the copper clad laminate during flipping and avoiding damage to the copper clad laminate; at the same time, several support rods are arranged on both sides of the front flip plate and the rear flip plate, and the edge position of the copper clad laminate is supported by several support rods, which can effectively avoid the bending deformation of the edge position of the copper clad laminate during the flipping process, thus further effectively avoiding the deformation and damage of the copper clad laminate during the flipping process;

[0020] 3. In the present invention, during the rotation of the front flip plate and the rear flip plate, the position of the guiding ring remains unchanged. When the copper clad laminate moves onto the front flip plate, one side of the copper clad laminate abuts against the rotating part area of the front flip plate, and the guiding ring is just here. In this way, the guiding ring and the rotating part area of the front flip plate can limit the whole side of the copper clad laminate, effectively avoiding the separation of the copper foil layer and the insulating layer of the copper clad laminate during the flipping process, and further avoiding the damage of the internal circuit; when the copper clad laminate is transferred to the rear flip plate, similarly, the guiding ring and the rotating part area of the rear flip plate can limit the whole side of the copper clad laminate;

[0021] 4. In the present invention, by successively restricting the copper clad laminate with the front pressing plate and the rear pressing plate during the flipping process of the copper clad laminate, and cooperating with the guiding ring, it can further effectively avoid the separation of the copper foil layer and the insulating layer of the copper clad laminate during the flipping process and avoid the damage of the internal circuit.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] As Figures 1 - 3 shown, a device for preventing misalignment of a copper clad laminate stack includes a conveyor roller 1, and the device further includes:

[0032] Electrically conductive rod 2, the electrically conductive rod 2 is installed on the inner walls of the two front ends of the conveying of the conveyor roller 1, the top of the electrically conductive rod 2 is flush with the top of the conveyor roller 1, the electrically conductive rod 2 is connected to an external power supply device, and the electrically conductive rod 2 is also connected to a processor 3;

[0033] Front flap 4 and rear flap 5, the front flap 4 and the rear flap 5 are installed in the middle section of the conveyor roller 1, the front flap 4 and the rear flap 5 are hinged together, the rotating center position of the front flap 4 and the rear flap 5 is connected to a coaxial drive member 6 through a rotating shaft 61, the coaxial drive member 6 makes the front flap 4 and the rear flap 5 rotate coaxially, and makes the front flap 4 and the rear flap 5 rotate towards each other or away from each other, and the processor 3 is connected to the coaxial drive member 6.

[0034] In one case of this embodiment, the current provided by the external power supply device that powers the energizing rod 2 is within the normal tolerance range of the copper clad laminate; the coaxial driving member 6 can be two motors, which are respectively connected to the front flap 4 and the rear flap 5 through two rotating shafts 61, or can be other components that can rotate the front flap 4 and the rear flap 5 coaxially and make the front flap 4 and the rear flap 5 rotate towards each other or away from each other.

[0035] In actual application of this embodiment, the worker places the copper clad laminate on the conveying roller 1, and the copper clad laminate moves through the conveyance of the conveying roller 1. When the copper clad laminate moves to the position of the two energizing rods 2, if the copper foil layer of the copper clad laminate contacts the conveying roller 1, at this time the energizing rod 2 will contact the copper foil layer, and the current will flow. At this time, the processor 3 will receive a signal. When the copper clad laminate moves to the position of the front flap 4, since the rotating end of the front flap 4 is higher than the surface of the front flap 4, at this time the copper clad laminate is restricted and cannot continue to move. The processor 3 simultaneously controls the coaxial driving member 6 to start. The coaxial driving member 6 makes the front flap 4 and the rear flap 5 rotate towards each other through the rotating shaft 61, so that the copper clad laminate slowly approaches the rear flap 5 until the front flap 4 and the rear flap 5 overlap. Then, it controls the coaxial driving member 6 to reverse the rotating shaft 61, so that the front flap 4 and the rear flap 5 rotate away from each other, so that the copper clad laminate is located on the rear flap 5. When the rear flap 5 rotates to the horizontal state, the copper clad laminate is flipped by 180°; if the insulating layer of the copper clad laminate contacts the conveying roller 1, at this time the energizing rod 2 will contact the insulating layer, and the current cannot flow, and the copper clad laminate will continue to move; through the above steps, the insulating layer of the copper clad laminate passing through the front flap 4 and the rear flap 5 is in contact with the conveying roller 1, so that the order is not easy to go wrong during subsequent stacking, thus effectively avoiding the waste of the laminated copper clad laminate caused by the wrong order of the multi-layer copper clad laminates;

[0036] The copper clad laminate is flipped through the cooperation of the front flap 4 and the rear flap 5. The front flap 4 and the rear flap 5 both have a supporting effect and a protective effect on the copper clad laminate during the flipping process of the copper clad laminate, effectively avoiding the copper clad laminate from being subjected to a torsional force during the flipping process, thus effectively avoiding the deformation of the copper clad laminate, resulting in damage or direct scrapping of the copper clad laminate;

[0037] The energized rod 2 is used to detect whether the contact surface between the copper clad laminate and the conveying roller 1 is an insulating layer. Compared with the scanners or other image recognition devices in the prior art, the energized rod 2 is not prone to errors during detection, and can smoothly detect whether the sequence of the copper clad laminates is incorrect. Moreover, the detection cost of the energized rod 2 is relatively low, thus reducing the production cost. To improve the detection accuracy, the energized rod 2 can be used in combination with a scanner or other image recognition devices. In this way, when the damaged copper foil contacts the conveying roller 1, although the energized rod 2 cannot detect it, the scanner and other image recognition devices can detect it. In this way, the copper clad laminates corresponding to the damaged copper foil can be screened out, thus avoiding the damaged copper clad laminates from entering the hot press for hot pressing, and further avoiding the scrapping of the entire copper clad laminate, while also reducing the production cost.

[0038] Further, a plurality of adsorption components I 41 are installed on the surface of the front flip plate 4, and a plurality of adsorption components II 51 are installed on the surface of the rear flip plate 5.

[0039] In one case of this embodiment, both the adsorption component I 41 and the adsorption component II 51 can be a combination of an air pump and a suction cup.

[0040] In the actual application of this embodiment, when the copper clad laminate is located on the surface of the front flip plate 4, the copper clad laminate is sucked by the adsorption component I 41. In this way, the copper clad laminate is not prone to displacement during the flipping process of the front flip plate 4, thus ensuring the stability of the copper clad laminate during flipping, effectively avoiding the copper clad laminate from falling off the front flip plate 4 during flipping, and avoiding damage to the copper clad laminate. When the front flip plate 4 and the rear flip plate 5 overlap, the adsorption component I 41 is closed and the adsorption component II 51 is activated to suck the copper clad laminate, so that the copper clad laminate is smoothly transferred to the rear flip plate 5, avoiding the copper clad laminate from detaching from the front flip plate 4 and the rear flip plate 5 when the front flip plate 4 and the rear flip plate 5 rotate away from each other, and at the same time improving the stability of the copper clad laminate during the rotation of the rear flip plate 5, effectively avoiding damage to the copper clad laminate during the flipping process.

[0041] Further, a plurality of support rods 10 are arranged on both sides of the front flip plate 4 and the rear flip plate 5.

[0042] In one case of this embodiment, the support rods 10 are located at positions between adjacent conveying rollers 1.

[0043] In the actual application of this embodiment, when the copper clad laminate moves onto the front flip plate 4 or the rear flip plate 5, the edge position of the copper clad laminate is supported by a plurality of support rods 10. In this way, it can effectively avoid the bending deformation of the edge position of the copper clad laminate during the flipping process, and further effectively avoid the deformation and damage of the copper clad laminate during the flipping process.

[0044] Further, U-shaped frames 11 are installed at both ends of the rotating shaft 61, and telescopic members 12 are installed at the bottom of the U-shaped frames 11.

[0045] In one case of this embodiment, the telescopic member 12 can be a cylinder or other components capable of telescopic driving; the telescopic member 12 is connected to the processor 3.

[0046] In the actual application of this embodiment, in the initial state, the tops of the front flap 4 and the rear flap 5 are both located below the top of the conveyor roller 1. When the insulating layer of the copper clad laminate passes through the energizing rod 2, the copper clad laminate continues to move, and the middle section of the conveyor roller 1 is in a hollow state. At this time, the suction components one 41 and two 51 on the front flap 4 and the rear flap 5 blow air upward, so that there is an upward blowing air flow in the hollow middle section of the conveyor roller 1. This air flow can support the moving copper clad laminate, effectively preventing the copper clad laminate from bending and deforming when it moves to the hollow part in the middle section of the conveyor roller 1 and being damaged; when the copper foil layer of the copper clad laminate passes through the energizing rod 2, the processor 3 will control the telescopic member 12 to extend, so that the tops of the front flap 4 and the rear flap 5 move to be flush with the top of the conveyor roller 1, thereby ensuring that the copper clad laminate can be flipped.

[0047] As Figures 3 - 6 shown, a number of guiding rings 7 are sleeved through between the front flap 4 and the rear flap 5. The guiding rings 7 are coaxial with the rotating shaft 61. The guiding rings 7 are fixed to the U-shaped frame 11 through the connecting rods 111. The front flap 4 and the rear flap 5 rotate around the guiding rings 7 when rotating.

[0048] It should be noted that during the flipping process of the copper clad laminate, due to insufficient adhesion of the adhesive between the copper foil layer and the insulating layer, the stress generated during the flipping process may cause delamination or cracking at the bonding part between the copper foil and the insulating layer, resulting in the separation of the copper foil and the insulating layer, thus damaging the integrity of the circuit; according to the above problems, a corresponding mechanism is set up to solve this problem.

[0049] In the actual application of this embodiment, during the rotation of the front flap 4 and the rear flap 5, the position of the guiding ring 7 remains unchanged. When the copper clad laminate moves onto the front flap 4, one side of the copper clad laminate abuts against the rotating part area of the front flap 4, and the guiding ring 7 is exactly here. In this way, the guiding ring 7 and the rotating part area of the front flap 4 can limit the whole side of the copper clad laminate, effectively preventing the separation of the copper foil layer and the insulating layer during the flipping process of the copper clad laminate, and further preventing the internal circuit from being damaged; when the copper clad laminate is transferred to the rear flap 5, similarly, the guiding ring 7 and the rotating part area of the rear flap 5 can limit the whole side of the copper clad laminate.

[0050] Further, an outer guide groove 71 is provided outside the guide ring 7, and an inner guide groove 72 is provided inside the guide ring 7. A front pressing plate 73 and a rear pressing plate 75 are respectively and slidably installed in the outer guide groove 71. Through holes 13 for the front pressing plate 73 and the rear pressing plate 75 to pass through are provided on both the front flap 4 and the rear flap 5. A first magnet 74 and a second magnet 76 are respectively and slidably installed in the inner guide groove 72. The first magnet 74 attracts the front pressing plate 73, and the second magnet 76 attracts the rear pressing plate 75. The first magnet 74 and the second magnet 76 are respectively located at both ends of the inner guide groove 72. Elastic members 77 are connected between the first magnet 74 and the second magnet 76 and the ends of the inner guide groove 72. A front connecting pipe 78 and a rear connecting pipe 79 are respectively connected outside the guide ring 7. The front connecting pipe 78 is located at the position between the first magnet 74 and the end of the inner guide groove 72, and the rear connecting pipe 79 is located at the position between the second magnet 76 and the end of the inner guide groove 72. The front connecting pipe 78 is connected to the air outlet end of the first adsorption assembly 41, and the rear connecting pipe 79 is connected to the air outlet end of the second adsorption assembly 51.

[0051] In one case of this embodiment, the part of the front pressing plate 73 close to the first magnet 74 is made of a magnetic material, and this part of the magnetic material attracts the first magnet 74; the part of the rear pressing plate 75 close to the second magnet 76 is also made of a magnetic material, and this part of the magnetic material attracts the second magnet 76.

[0052] In actual application of this embodiment, when the copper clad laminate moves onto the front flip plate 4, the first adsorption component 41 starts to work and sucks the copper clad laminate. The air outlet end of the first adsorption component 41 is connected to the front connecting pipe 78, so that air enters the inner guiding groove 72 through the front connecting pipe 78. When there is more and more air, the compressed air will push the first magnetic block 74 to move along the inner guiding groove 72. When the first magnetic block 74 moves, it drives the front pressing plate 73 to move, making the front pressing plate 73 slowly approach the front flip plate 4 and finally making the front pressing plate 73 abut against the surface of the copper clad laminate, so as to further limit the copper clad laminate. When the copper clad laminate is transferred to the rear flip plate 5, the first adsorption component 41 stops operating. At this time, air will no longer enter the inner guiding groove 72, and with the resilience of the elastic member 77, the front pressing plate 73 returns to its original position. After the copper clad laminate is transferred to the rear flip plate 5, the second adsorption component 51 starts to work and sucks the copper clad laminate. The air outlet end of the second adsorption component 51 is connected to the rear connecting pipe 79, so that air enters the inner guiding groove 72 through the rear connecting pipe 79. When there is more and more air, the compressed air will push the second magnetic block 76 to move along the inner guiding groove 72. When the second magnetic block 76 moves, it drives the rear pressing plate 75 to move, making the rear pressing plate 75 slowly approach the rear flip plate 5 and finally making the rear pressing plate 75 abut against the surface of the copper clad laminate, so as to further limit the copper clad laminate, and further avoid the separation of the copper foil layer and the insulating layer during the flipping process of the copper clad laminate. By using the front pressing plate 73 and the rear pressing plate 75 to successively limit the copper clad laminate during the flipping process of the copper clad laminate and cooperating with the guiding ring 7, it can further effectively avoid the separation of the copper foil layer and the insulating layer during the flipping process of the copper clad laminate and avoid damage to the internal circuit.

[0053] As Figure 1 and Figure 2 shown, an electrostatic elimination mechanism 8 is installed between the inner walls at the conveying rear end of the conveying roller 1.

[0054] In one case of this embodiment, the electrostatic elimination mechanism 8 can be an electrostatic elimination device such as an ion blower.

[0055] In actual application of this embodiment, since an electric current is passed through the copper foil layer of the copper clad laminate when it passes through the energizing rod 2, at the moment of power off, the sudden change of the current may cause induced charges to remain on the copper foil surface, and static electricity will also be generated due to the friction when the copper foil contacts the conveying roller 1. The static charges remaining on the copper foil surface will attract charged dust particles in the air through Coulomb force, or polarize neutral dust and adsorb it. During subsequent hot pressing, these dusts are embedded between the copper foil and the base material, resulting in poor local adhesion, forming bubbles or delamination, thus reducing the quality of the copper clad laminate after pressing. Therefore, before the copper clad laminate enters the hot press for hot pressing, the copper foil layer of the copper clad laminate is subjected to electrostatic elimination treatment by an electrostatic elimination device, which can effectively avoid the adsorption of dust on the copper foil layer surface and avoid the influence of dust on the quality of the copper clad laminate after hot pressing.

[0056] AsFigure 1 As shown in the figure, a hot press includes the above-mentioned anti-misalignment device for stacked copper clad laminates and a hot press 9. A positioning frame 91 is provided on the hot press 9. The positioning frame 91 is located at the conveying end of the conveying roller 1. The copper clad laminates with adjusted order on the conveying roller 1 enter the positioning frame 91 and are stacked layer by layer in sequence, effectively avoiding the wrong order when stacking the copper clad laminates.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
