Description

[0002] Aluminum-based copper-clad laminate is one of the common substrate materials in the electronics industry. It has good thermal conductivity and electrical properties, and can be applied to high-power electronic circuits to meet different circuit requirements. In the production process of aluminum-based copper-clad laminates, aluminum-based copper-clad laminates are often required to be coated. Coating can prevent the copper foil from oxidation, corrosion and mechanical damage, thereby improving the stability and service life of the aluminum-based copper-clad laminate.

[0003] However, aluminum-based copper-clad laminates are prone to bubbles during the lamination process. If these bubbles are not eliminated, the edges and corners of the aluminum-based copper-clad laminates may be blocked by bubbles when they are collected and trimmed after cutting, resulting in deviations in the arrangement of the aluminum-based copper-clad laminates, affecting the subsequent processing of the aluminum-based copper-clad laminates. What's worse, the edges and corners of the aluminum-based copper-clad laminates may scratch the bubbles and damage the lamination, causing the lamination to no longer be able to provide the original protective function for the aluminum-based copper-clad laminates, thereby affecting the service life of the aluminum-based copper-clad laminates.

The aluminum-based copper-clad laminate is continuously released, and the aluminum-based copper-clad laminate first passes through the unwinding roller 103 where the lower film roll is located, and the end of the lower film roll is pasted on the upper surface of the aluminum-based copper-clad laminate.

After that, the aluminum-based copper-clad laminate passes through the unloading roller 103 where the upper film roll is located, and the end of the upper film is adhered to the upper surface of the aluminum-based copper-clad laminate at this time, thereby realizing the double-sided lamination of the aluminum-based copper-clad laminate by the device; finally, when the end of the aluminum-based copper-clad laminate moves to the position of the unloading roller 103 on the upper left, the end of the aluminum-based copper-clad laminate is fixed on the inner cylinder, and the servo motor A104 is started to control the unloading roller 103 to reel the aluminum-based copper-clad laminate, that is, to collect the aluminum-based copper-clad laminate that has completed the lamination, and the aluminum-based copper-clad laminate is collected in the state of coils, so as to facilitate the subsequent storage or transportation of the aluminum-based copper-clad laminate.

[0037] See also Figure 1-Figure 4The defoaming mechanism 3 includes: a servo motor C301 fixedly mounted on the rear side of the support frame 101; a control rod 302 rotatably mounted on the support frame 101, four control rods 302 are arranged in a row, the servo motor C301 and the control rod 302 at the edge are fixedly mounted using a coupling, and each adjacent two control rods 302 are driven and installed using a transmission member 701, that is, three groups of transmission members 701 are connected between the four control rods 302 to achieve synchronous rotation of all control rods 302, and the transmission member 701 is composed of a transmission wheel and a transmission belt; each control rod 302 is provided with a section of reciprocating thread 303, the reciprocating thread 303 only occupies a single side of the control rod 302, and the front and rear positions of the reciprocating threads 303 on two adjacent control rods 302 are staggered; a moving frame 304 threadedly mounted on the reciprocating thread 303 of each control rod 302, and the control rod 302 rotates to control the moving frame 304 to reciprocate Move forward and backward; a mobile frame 305 slidably installed at the lower part of the mobile frame 304; a pressure wheel group 306 rotatably installed on the mobile frame 305, the pressure wheel group 306 is provided with two pressure wheels of different sizes, the large pressure wheel and the small pressure wheel are respectively arranged at the front and rear of the mobile frame 305, in particular, the direction of the small pressure wheel on the mobile frame 305 is consistent with the direction of the reciprocating thread 303 on the control rod 302 where the reciprocating thread 303 is located, for example, the small pressure wheel on the control rod 302 on the front side is located at the front side of the mobile frame 305; an elastic member A307 fixedly installed between each mobile frame 305 and the mobile frame 304, the elastic member A307 is specifically a compression spring, and the elastic member A307 is used to reset the mobile frame 305; a guide component is arranged between the support frame 101 and the pressure wheel group 306, the guide component is used to cyclically guide the pressure wheel group 306 to move, so that the pressure wheel group 306 moves along a specific trajectory from the middle to both sides.

[0038] The guide assembly includes: a slot plate 308 fixedly mounted on the support frame 101, wherein four slot plates 308 are provided and are respectively located on the left side of each control rod 302 and corresponding to each control rod 302. A circulating slot is provided on the slot plate 308, and an inclined section is provided at a position near the edge of the slot; a guide shaft 309 fixedly mounted on the movable frame 305, and the guide shaft 309 is slidably mounted in the slot of the slot plate 308; a guide plate 310 rotatably mounted on the slot plate 308, and the guide plate 310 is located at the position where the inclined section of the slot is located. A limiting portion 312 is provided on the slot plate 308, and the limiting portion 312 is located below the guide plate 310 to limit the guide plate 310 from rotating downward, so that the guide shaft 309 moves unidirectionally in the slot of the slot plate 308; an elastic member B311 fixedly mounted between the slot plate 308 and the guide plate 310, and the elastic member B311 is specifically a torsion spring, and the elastic member B311 is used to reset the guide plate 310.

[0039] Two groups of defoaming mechanisms 3 are arranged on the support frame 101. The two groups of defoaming mechanisms 3 defoam both sides of the aluminum-based copper-clad laminate respectively. The two groups of defoaming mechanisms 3 are respectively located above the two layers of conveyor belts 202, and are respectively arranged on the sides of two unloading rollers 103 for storing film rolls, specifically located below the two unloading rollers 103 in the lower position of the conveying direction corresponding to the conveying belt 202. For example, the conveying direction of the conveying belt 202 below the lower unloading roller 103 is from left to right, so the lower direction of the conveying direction corresponding to the conveying belt 202 is right, that is, the lower layer defoaming mechanism 3 is located to the right of the lower layer unloading roller 103, and by analogy, the upper layer defoaming mechanism 3 is located to the left of the upper layer unloading roller 103.

[0040] The servo motor C301 controls the control rod 302 to rotate, and controls the moving frame 304 and the moving frame 305 together with the pressure wheel group 306 to move back and forth reciprocatingly, and under the circular guidance of the guide shaft 309 and the groove of the groove plate 308, the pressure wheel group 306 will also be guided by the groove of the groove plate 308 to move up and down. Specifically, taking the control rod 302 with the reciprocating thread 303 on the front side as an example, when the control rod 302 controls the upper pressure wheel group 306 to move forward, the guide shaft 309 is located at the lower layer position of the groove of the groove plate 308, then the pressure wheel group 306 can contact the aluminum-based copper-clad laminate and the film, and roll and press in the direction from the middle to the front side, pushing the bubbles between the aluminum-based copper-clad laminate and the film outward until the bubbles dissipate from the edge between the aluminum-based copper-clad laminate and the film, thereby achieving bubble elimination;

[0041] Subsequently, the guide shaft 309 is moved to the inclined section at the front end of the groove path of the groove plate 308. Under the guiding action of the inclined section, the movable frame 305 is moved upward by the guide shaft 309, and the elastic member A307 is compressed, so that the pressure wheel group 306 is separated from the aluminum-based copper-clad plate and the film. At the same time, during the process, the guide shaft 309 pushes the guide plate 310 to rotate upward, and the elastic member B311 is twisted. After the guide shaft 309 passes through the guide plate 310, the elastic member B311 resets the guide plate 310, so that the guide shaft 309 moves to the top of the guide plate 310. In addition, the guide plate 310 is restricted by the restriction portion 312, so that the guide plate 310 can be limited. The guide shaft 309 cannot move downward, that is, at this time, the guide shaft 309 enters the upper layer of the slot of the slot plate 308. Therefore, when the movable frame 305 moves backward, the guide shaft 309 will move backward from the upper layer of the slot of the slot plate 308, and the pressure wheel group 306 will no longer contact the aluminum-based copper-clad laminate and the film until the guide shaft 309 is moved to the rear section of the slot of the slot plate 308. Under the action of the elastic member A307, the guide shaft 309 can return to its lower layer along the slot of the slot plate 308, so that when the pressure wheel group 306 moves forward later, it can press and contact with the aluminum-based copper-clad laminate and the film again to defoam.

[0042] By analogy, for the pressure wheel group 306 on the control rod 302 with the reciprocating thread 303 on the rear side of the control rod 302, during the process of reciprocating forward and backward movement, the pressure wheel group 306 can defoam between the aluminum-based copper-clad laminate and the film only when it is in the direction from front to back, otherwise the pressure wheel group 306 will lose contact with the aluminum-based copper-clad laminate and the film.

[0043] In summary, when all the pressure wheel groups 306 move back and forth, they will only be able to squeeze the bubbles on the aluminum-based copper-clad laminate and the film from the middle position to both sides, and when moving from both sides to the middle position, the pressure wheel groups 306 will break contact with the aluminum-based copper-clad laminate and the film, preventing the bubbles from being squeezed and concentrated in the middle position of the aluminum-based copper-clad laminate and unable to be discharged, or even causing the volume of the bubbles to increase.

[0044] In particular, the arrangement direction of the large pressure wheel and the small pressure wheel is such that when the pressure wheel group 306 squeezes the bubbles from the middle to both sides, the small pressure wheel will come into contact with the bubbles first. Therefore, for small bubbles, the small pressure wheel can directly discharge them, and the large pressure wheel will then supplement the defoaming work of the small pressure wheel; for large bubbles, since the size of the bubbles is too large, if the large pressure wheel directly discharges them, there may be residual bubbles. Therefore, in the device, through the arrangement and coordination of the position of the pressure wheel group 306, the small pressure wheel first comes into contact with the bubbles to disperse the bubbles, and then the large pressure wheel can better defoam.

[0046] When the aluminum-based copper-clad laminate is moved by the conveyor belt 202, the pressure roller A401 presses the aluminum-based copper-clad laminate toward the conveyor belt 202, thereby increasing the friction between the aluminum-based copper-clad laminate and the conveyor belt 202, thereby improving the effect of the conveyor belt 202 in transporting the aluminum-based copper-clad laminate; before the film is attached to the aluminum-based copper-clad laminate, the film is passed through the guide roller 406, which provides tension for the film, and then the film is passed under the pressure roller B404 and attached to the aluminum-based copper-clad laminate. Therefore, under the action of the elastic member C403, the pressure roller B404 presses the film toward the aluminum-based copper-clad laminate, that is, the force exerted by the elastic member C403 can make the film better attached to the aluminum-based copper-clad laminate, thereby improving the attachment effect of the film.

The transmission member is composed of a transmission wheel and a transmission belt to realize synchronous transmission of the two rotating shafts 601, and a transmission member 701 is also used for transmission and installation between one of the rotating shafts 601 and the transport roller 201. The transmission member 701 is composed of a gear, a transmission wheel and a transmission belt. The transmission wheel and the transmission belt realize synchronous transmission of the rotating shaft 601 and the transport roller 201. The gear realizes reversal so that the rotation direction of the rotating shaft 601 is opposite to the transport direction of the transport belt 202 below it; a sleeve 602 is provided on the rotating shaft 601, and the sleeve 602 and the transport roller 201 are connected to each other.

[0050] When the rotating shaft 601 rotates, it will drive the sleeve 602 and the cleaning roller 605 thereon to remove dust from the aluminum-based copper-clad laminate. At the same time, the sleeve 602 rotates, so that its upper push rod 603 moves around the extrusion ring 604. Under the cooperation of the wave structure of the extrusion ring 604 and the elastic member E606, the sleeve 602 is moved forward and backward at the same time, thereby improving the dust removal effect of the cleaning roller 605; the rotation of the transport roller 201 will synchronously drive the two rotating shafts 601 to rotate through the transmission member 701, and the rotation direction of the rotating shaft 601 is opposite to the rotation direction of the transport roller 201, that is, opposite to the movement direction of the aluminum-based copper-clad laminate, thereby further improving the dust removal effect of the cleaning roller 605; that is, before the aluminum-based copper-clad laminate passes under the unloading roller 103 where the film roll is placed and is coated, the aluminum-based copper-clad laminate will first pass through the cleaning roller 605 and be dusted by the cleaning roller 605, thereby avoiding the formation of irremovable bubbles on the aluminum-based copper-clad laminate after coating due to residual dust.
