Description

Technical Field

[0001] This utility model belongs to the field of composite copper clad laminate manufacturing technology, and particularly relates to an anti-slip device for laminating composite copper clad laminates. Background Technology

[0002] Composite copper clad laminate is a laminated material made by laminating multiple layers of copper foil, prepreg, and core board under high temperature and pressure. It is widely used in the manufacture of multilayer printed circuit boards. In the production process of composite copper clad laminate, a base plate is placed underneath the multilayer copper clad laminate, a cover plate is added on top, and then it is pressed together using a press.

[0003] However, if the copper-clad laminate stack is not positioned to prevent slippage before lamination, it is prone to slippage due to resin flow or mechanical vibration during the initial pressing stage. Currently, the industry commonly uses a frame for anti-slip positioning, which involves using a square metal frame to surround the copper-clad laminate and then securing it with four curved metal plates on the frame. While this method can limit slippage to some extent, the square metal frame needs to be manually loaded and unloaded before and after each lamination, making the operation cumbersome and difficult to meet the needs of automated, high-speed production lines.

[0004] Therefore, there is a particular need for an anti-slip device for laminating composite copper-clad laminates to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing frame-type anti-slip positioning methods, which require frequent manual loading and unloading, are cumbersome to operate, and are difficult to adapt to the needs of automated and efficient production, this utility model provides an anti-slip device for laminating composite copper-clad laminates.

[0006] This utility model is achieved through the following technical means: an anti-slip device for laminating composite copper-clad laminates, comprising a laminating table, a support frame, a bearing platform, a controller, and an anti-slip mechanism. The support frame and the bearing platform are fixedly connected to the top of the laminating table. The support frame has a frame structure and is arranged around the upper part of the bearing platform. The controller is installed on the front side of the upper part of the laminating table. It also includes a second cylinder, a pneumatic suction cup unit, an upper cover plate, and an anti-slip component. The second cylinder is installed on the upper part of the support frame. The pneumatic suction cup unit is installed at the end of the piston rod of the second cylinder. The second cylinder and the pneumatic suction cup unit are electrically connected to the controller. The upper cover plate is adsorbed at the lower part of the pneumatic suction cup unit. The upper cover plate and the support frame form a sliding fit.

[0007] Preferably, the upper cover plate is provided with an anti-slip mechanism, which includes a third cylinder, a connecting plate, a baffle, a pulley, a dual-axis motor, and a screw. A third cylinder is installed on the front, rear, left, and right sides of the upper cover plate. A connecting plate is installed at the end of the piston rod of each third cylinder. The connecting plates on the left and right sides are larger than those on the front and rear sides. A baffle is fixed to the side of each of the four connecting plates closest to the geometric center of the upper cover plate. A dual-axis motor is installed inside both the left and right connecting plates. The second and third cylinders and the dual-axis motor are electrically connected to the controller. A screw is fixed to each of the two output shafts of each dual-axis motor. Two symmetrically arranged guide grooves are provided on both the left and right connecting plates. A pulley is slidably installed in each guide groove. The screw horizontally passes through the corresponding pulley and forms a threaded engagement with it.

[0008] Preferably, it also includes a cylinder and a centering plate. Cylinders are installed on the front, back, left and right sides of the upper part of the pressing platform. Cylinders are electrically connected to the controller. A centering plate is installed at the end of the piston rod of each cylinder.

[0009] Preferably, the bottom surface of the center plate is at the same horizontal level as the top surface of the supporting platform.

[0010] Preferably, the geometric center of the top cover plate is aligned with the geometric center of the support platform in the vertical direction.

[0011] Preferably, the baffle is made of an elastic material.

[0012] Preferably, the two screws on the same dual-shaft motor have opposite thread directions.

[0013] Preferably, the pulley surface and the side of the corresponding baffle closest to the geometric center of the upper cover plate are located in the same vertical plane.

[0014] The beneficial effects of this utility model are as follows: 1. Through the coordinated operation of cylinder 2, pneumatic suction cup unit, top cover plate and anti-slip components, anti-slip positioning of copper clad laminate stacks is achieved, effectively preventing material slippage of copper clad laminate stacks. The entire process is controlled by the controller and requires no manual intervention, significantly improving work efficiency and automation level.

[0015] 2. By setting cylinder one and centering plate, the copper-clad laminate can be automatically centered, ensuring that the reference of subsequent top cover plate pressing and the surrounding baffles and pulley clamping operation are consistent, improving anti-slip positioning accuracy and avoiding positioning deviation caused by initial position offset.

[0021] Example: An anti-slip device for laminating composite copper-clad laminates, such as... Figures 1-4 As shown, the assembly includes a pressing table 1, a support frame 101, a carrying platform 102, a controller 2, and an anti-slip mechanism. The support frame 101 and the carrying platform 102 are fixedly connected to the top of the pressing table 1. The support frame 101 has a frame structure and is arranged around the upper part of the carrying platform 102. The controller 2 is bolted to the upper front side of the pressing table 1. The controller 2 is a programmable logic controller, model Huichuan Easy. The 521-24T4DT also includes a second cylinder 5, a pneumatic suction cup unit 6, an upper cover plate 7, and an anti-slip assembly. The upper part of the support frame 101 is bolted to the second cylinder 5. The piston rod of the second cylinder 5 extends vertically downward, and the end of the piston rod is bolted to the pneumatic suction cup unit 6. Both the second cylinder 5 and the pneumatic suction cup unit 6 are electrically connected to the controller 2. The lower part of the pneumatic suction cup unit 6 is attached to the upper cover plate 7. The upper cover plate 7 can cover the stack of multiple copper-clad laminates from above. The upper cover plate 7 and the support frame 101 form a sliding fit. The geometric center of the upper cover plate 7 is aligned with the geometric center of the bearing platform 102 in the vertical direction.

[0022] like Figures 1-4As shown, the upper cover plate 7 is equipped with an anti-slip mechanism, which includes a cylinder 80, a connecting plate 81, a baffle 82, a pulley 83, a dual-axis motor 84, and a screw 85. Cylinders 80 are bolted to the front, rear, left, and right sides of the upper cover plate 7. The piston rod end of each cylinder 80 is bolted to a connecting plate 81. The connecting plates 81 on the left and right sides are larger than those on the front and rear sides. A baffle 82 is fixedly connected to the side of each connecting plate 81 closest to the geometric center of the upper cover plate 7. The baffle 82 is made of an elastic material, such as silicone, to prevent scratching the edges of the copper-clad laminate. Dual-axis motors 84 are bolted to the interior of both the left and right connecting plates 81. Cylinders 80, 80, and 84 are all electrically connected to the controller 2. Each dual-axis motor 84 has two... Each output shaft is fixedly connected to a screw 85 via a coupling. Two symmetrically arranged guide grooves 86 are provided on both the left and right connecting plates 81. A pulley 83 is slidably installed in each guide groove 86. The screw 85 passes horizontally through the corresponding pulley 83 and forms a threaded engagement with the pulley 83 to drive the pulley 83 to move along the guide groove 86. The two screws 85 on the same dual-axis motor 84 have opposite thread directions. For example, the front screw 85 has a right-hand thread and the rear screw 85 has a left-hand thread. When the two screws 85 rotate clockwise, they can drive the two longitudinally aligned pulleys 83 to move inward synchronously. The wheel surface of the pulley 83 and the side of the corresponding baffle 82 near the geometric center of the upper cover plate 7 are located in the same vertical plane, ensuring that the pulley 83 and the baffle 82 contact the side edge of the copper-clad laminate synchronously during operation.

[0023] like Figure 1 As shown, it also includes cylinder 3 and centering plate 4. Cylinder 3 is bolted to the front, back, left and right sides of the upper part of the pressing table 1. Cylinder 3 is electrically connected to the controller 2. The piston rod end of each cylinder 3 is bolted to the centering plate 4. The bottom surface of the centering plate 4 is at the same level as the top surface of the bearing platform 102, ensuring that the centering plate 4 can accurately push the copper-clad laminate on the bearing platform 102.

[0024] In operation, the operator first stacks the multi-layer copper-clad laminates on the support platform 102. Then, the controller 2 activates four cylinders 3, controlling the piston rods of the four cylinders 3 to extend synchronously, driving the four centering plates 4 to move towards the geometric center of the support platform 102. This initial centering of the copper-clad laminate stack is achieved from four directions (front, back, left, and right) to ensure accurate positioning. After centering, the piston rods of the four cylinders 3 are retracted, causing the centering plates 4 to reset and detach from the copper-clad laminate stack. Then, the two dual-axis motors 84 are activated, causing their output shafts to drive the four screws 85 to rotate synchronously clockwise, driving the pulleys 83 to move inward along the guide grooves 86. When the pulley 83 moves inward to the appropriate position, the two dual-axis motors 84 are turned off. Then, cylinder 2 5 is started, and the piston rod of cylinder 2 5 is extended downward, driving the pneumatic suction cup unit 6 to descend, so that the top cover plate 7 is attached to the top of the copper clad laminate stack. Then, the four cylinders 3 80 are started, and the piston rods of the four cylinders 3 80 are extended synchronously, driving each connecting plate 81 and baffle 82 to approach the side edge of the copper clad laminate stack until the baffle 82 and the pulley 83 contact the side edge of the copper clad laminate stack, forming a uniform clamp. At this time, the copper clad laminate stack is completely constrained by the combined action of the top cover plate 7, the surrounding baffles 82 and the pulley 83, effectively preventing material leakage.
