Description

Technical Field

[0001] The present invention relates to the technical field of intelligent temperature control hydraulics for multi-layer PCBs, and more particularly to an intelligent temperature control hydraulic device for laminating multi-layer PCBs. Background Art

[0002] PCB is also called printed circuit board. However, multi-layer PCB refers to a printed circuit board with more than two layers. It is composed of connecting wires on several layers of insulating substrates and pads for assembling and welding electronic components. It has the function of conducting the circuits of each layer and insulating them from each other. Therefore, when the multi-layer PCB is pressed together, the PCB temperature is increased by a dedicated intelligent temperature-controlled hydraulic device, and then the various layers are bonded together at high temperature, ensuring a close bond between each layer, thereby enhancing the mechanical properties and stability of the multi-layer board. To this end, the temperature can be controlled within the tolerance range of the circuit board through the effect of the intelligent temperature-controlled hydraulic pressure, avoiding damage to the circuit board caused by excessively high temperature or reduced bonding stability caused by excessively low temperature. Then, based on the characteristics of the hydraulic pressure, the bonding accuracy and stability between the circuit boards can be improved; In summary, the inventors have discovered that existing intelligent temperature-controlled hydraulic devices have the following major drawbacks: Because the current intelligent temperature-controlled hydraulic devices cause the pressing plate to reciprocate up and down, driven by a liquid system, only the center of the pressing plate's surface is connected to the hydraulic rod of the hydraulic system, leaving its edges suspended. This can easily lead to tilting and instability caused by the inconsistent weight of the components carried by the edges, which can easily destroy the stable and parallel pressing accuracy of multi-layer PCBs; At the same time, the temperature-controlled carrier platform is disassembled and assembled based on independent equipment, so that its center point needs to be constantly calibrated so that it can coincide with the center of the hydraulic system's pressing plate. As a result, the continuous calibration process will reduce its own convenience of disassembly and maintenance and easily cause deviation of the center point, thereby reducing the pressing accuracy of multi-layer PCBs.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is further improved by the temperature-controlled bearing structure. After the central slider at the lower end of the parallel plate is installed parallel to the surface of the positioning base, the top ends of the four restraining rods can be aligned with the edge area of the pressing plate. Subsequently, the adjustment structure and the limit track in the rod body of the restraining rod are used to adjust the height of the top adsorption block, forcing it to pass through the edge of the pressing plate. Therefore, after the rod body passes through the corner position of the pressing plate, it can ensure that the center of the pressing plate and the center of the loading slot in the center of the temperature controller are aligned with each other. At the same time, the restraint of the rod body can ensure the stability of the pressing plate when it is reciprocating up and down using the hydraulic pressure, avoiding the shaking and instability caused by the hollowing of the edge, so as to improve the precision and stability of the pressing of multi-layer PCBs.

[0019] 2. After the adjustment structure of the present invention is further improved, the pull rod can be controlled by the vertical pulling of the pull block to slide in the vertical rail inside the rod body, so that the pull rod uses the locking head of the top top block to drive the adsorption block to slide up and down, so that the adsorption block can be reset into the rod body and can be separated from the penetration position of the press plate, achieving the effect of easy disassembly. Then, the fixed body in the center of the pull block can be locked inside the rod body by the rotating block to allow the bottom external threaded connecting column to be locked inside the rod body, ensuring that the adsorption block can maintain a stable height area after penetrating the press plate area, preventing the automatic sliding caused by the lack of fixing force at the bottom, and improving the connection firmness between components.

[0020] 3. After the temperature controller of the present invention is further improved, the temperature monitoring plate in the clamping frame can be powered and fixed through the temperature control bodies on the left and right sides of the overlapping plate, so that the temperature monitoring plate can cover the bottom layer of the PCB in the clamping frame in a parallel and stable state, and then can stably monitor the temperature conditions in the loading slot. Subsequently, the temperature limiting effect of the temperature control body can ensure that the temperature in the loading slot is maintained in a suitable range, further improving the pressing stability of the multi-layer PCB. Subsequently, the overlapping plate can be effectively improved through the "L" shape formed by the slider of the bottom limit assembly and the extended magnetic block. The connection stability with the parallel plate and the center slider can be improved by using the extended magnetic block on the side. After the slider is inserted, the extended magnetic block can be adsorbed on the side surface of the parallel plate and the center slider, so that the accuracy of the connection between the temperature controller and the parallel plate can be improved, and it is ensured that the position of the extended magnetic block on the side can be aligned with the center of the parallel plate after direct insertion.
