Description

Technical Field

[0001] The present invention relates to the field of PCB board processing and manufacturing, and in particular to a PCB board pressing plate forming and manufacturing device and a pressing plate manufacturing method thereof. Background Art

[0002] The PCB lamination and forming device is a specialized machine used in the printed circuit board (PCB) production process to press and form multiple layers of materials under high temperature and pressure. Its core function is to laminate materials such as copper foil and prepreg (PP) into a solid multi-layer PCB substrate, ensuring a tight structure without bubbles or offsets.

[0003] In the related art, manual pressing of PCB boards is usually adopted. However, manual pressing may cause the PCB boards to warp or not be pressed properly, resulting in excessive gaps between multi-layer PCB boards and inability to fit tightly, affecting the processing accuracy of the PCB boards. The height difference between PCB boards caused by warping also affects the forming efficiency of the multi-layer PCB boards. The existing pressing forming device can only complete a single pressing operation. However, when producing copper-clad laminates, when laminating the copper foil, the copper foil is directly covered on the substrate and then pressed. During long-term use and observation, it was found that when the substrate and copper foil are pressed together, if there is residual gas between the copper foil and the substrate, the copper foil will bulge and not fit tightly after being pressed to the substrate.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example:

[0036] like Figure 1-8 As shown, an embodiment of the present invention provides a PCB board pressing plate forming and manufacturing device, including a base 4, a bracket 3 installed on the upper end of the base 4, two pressing mechanisms 1 for pressing and smoothing installed on both sides of the bracket 3, and two auxiliary positioning tray assemblies 5. Auxiliary collecting assemblies 6 for flipping and retracting the auxiliary positioning tray assemblies 5 are installed on both sides of the front end surface of the base 4 near the midpoint. Hydraulic rods 2 are fixedly provided on both sides of the lower end of the bracket 3, and the output end of the lower end of the hydraulic rod 2 is fixedly connected to the pressing mechanism 1. Collection trays 7 are installed on one side of the front end and near the midpoint of the base 4.

[0037] Specifically, in the above-mentioned specific embodiment, the base 4 serves as a workbench, and a cantilever structure is formed by the bracket 3 arranged at the upper end. When press plate forming is required, the pressing mechanism 1 is pushed down by the hydraulic rod 2 to extrude the stacked raw materials inside the auxiliary positioning tray assembly 5 to perform press plate forming; since two sets of forming assemblies are designed, the synchronous operation of the two workstations can be achieved, thereby speeding up work efficiency. At the same time, the designed auxiliary collecting assembly 6 can flip the workpiece that has completed press plate forming outward for pouring out, thereby achieving the effect of rapid discharge.

[0038] Reference Figure 5-Figure 8 The pressing mechanism 1 includes an outer cover 101 and a lower cover 102. The outer cover 101 is fixed to the upper end of the lower cover 102 by bolts, and the upper end of the outer cover 101 is fixedly connected to the lower end of the hydraulic rod 2. A slide groove 107 is provided at the midpoint of the upper end surface of the lower cover 102. Two slide rails 1011 are fixedly provided on one side of the upper end surface of the lower cover 102. Guide rails 1012 are fixedly provided at the front and rear ends of the lower end surface of the lower cover 102 at the front and rear ends of the slide groove 107. The outer sides of the two slide rails 1011 are slidably sleeved with a connecting slide cover 106. The two The connecting slide cover 106 slides in opposite directions and is fixed with a No. 1 pressing plate 105 at one end. A driving motor 104 is fixedly provided at the midpoint of the upper end surface of the lower cover 102, and a gear 108 is fixedly provided at the output end of the driving motor 104. A rack 103 is slidably engaged with the interior of the slide groove 107. The outer sides of the two guide rails 1012 are slidably connected to the No. 2 pressing plate 1010 through guide blocks 1016, and the No. 2 pressing plate 1010 is respectively connected to the two No. 1 pressing plates 105 through two linkage rods 109.

[0039] Specifically, when in use, the hydraulic rod 2 is first used to push down the entire pressing mechanism 1 so that it is continuously close to the upper end of the auxiliary positioning tray assembly 5 and squeezes the stacked raw materials placed inside to perform press plate forming. During the press plate manufacturing process, the lower surfaces of the two No. 1 pressing plates 105 will first perform press plate forming on the entire stacked plate, and then the internally arranged drive motor 104 is started to drive the front end gear 108 to drive the rack 103 to move, and the rack 103 drives the lower end support 1015 to move, thereby driving the No. 2 pressing plate 1010 to move horizontally. In the process of the No. 2 pressing plate 1010 moving horizontally, it will push the linkage rod 109 due to its action, causing the two No. 1 pressing plates 105 to move outward and translate, thereby realizing the front and rear translational extrusion and the translational extrusion on both sides of the upper surface of the stacked plate, thereby realizing the extrusion and smoothing effect of internal bubbles and other factors, thereby improving the quality of press plate forming manufacturing.

[0040] Reference Figure 5-Figure 8, the lower end of the rack 103 is fixedly provided with a support 1015, and the support 1015 is slidably engaged with the lower end of the inner part of the slide groove 107, the lower end surface of the support 1015 is fixedly connected to the second pressing plate 1010, and the two guide blocks 1016 are respectively fixedly provided at the front and rear ends of one side of the upper end surface of the second pressing plate 1010, and the two ends of the two linkage rods 109 are rotatably sleeved with a connecting shaft 1014, and the two connecting shafts 1014 located on the two linkage rods 109 are respectively rotatably provided on the upper end of the second pressing plate 1010 and the fixed block 1013 fixed on the inner wall of the bent end of the No. 1 pressing plate 105;

[0041] Specifically, during use, when the No. 2 pressing plate 1010 moves laterally, it will drive the two linkage rods 109 to move together. The two ends of the linkage rod 109 are connected to the connecting shaft 1014 due to rotation. The connecting shaft 1014 connected at one end is fixed on the No. 1 pressing plate 105. At this time, the linkage rod 109 rotates and expands due to the driving force it receives, thereby pushing the two No. 1 pressing plates 105 to expand outward, and finally realizing the parallel state and linkage relationship of the two No. 1 pressing plates 105 and the No. 2 pressing plate 1010.

[0042] Reference Figure 5-Figure 8 The two No. 1 pressing plates 105 are both L-shaped plates, and the lower surfaces of the two No. 1 pressing plates 105 are in the same plane as the lower surface of the No. 2 pressing plate 1010; their lower surfaces are in the same plane, which can ensure uniformity during the extrusion process.

[0043] Reference Figure 2-Figure 4 The auxiliary positioning tray assembly 5 includes a bottom plate 502, a support plate 503 is fixedly provided at the midpoint of the upper end surface of the bottom plate 502, movable grooves 504 are opened on both sides and the front and rear ends of the upper end surface of the bottom plate 502, and a plurality of telescopic springs 505 are fixedly provided at the bottom end surfaces of the four movable grooves 504, wherein the upper ends of the telescopic springs 505 located in the four movable grooves 504 are fixedly provided with side plates 501;

[0044] Specifically, when the hydraulic rod 2 pushes down the pressing mechanism 1 to squeeze the auxiliary positioning tray assembly 5, the side plate 501 at the upper end is squeezed and moves downward, causing the internal telescopic spring 505 to contract. Since the raw material plate of the stacked structure is placed between the side plates 501, the side plates 501 play an auxiliary limiting and leveling effect, so that during the pressing plate forming and manufacturing process, the entire stacking state is in a relatively flat state, reducing the problem of offset and tilt.

[0045] Reference Figure 2The auxiliary collecting assembly 6 includes a No. 1 driving assembly 601, which is fixedly arranged on the front end surface of the base 4. A driving shaft 602 is rotatably provided on the upper end of the No. 1 driving assembly 601, and a No. 2 driving assembly 604 is fixedly provided on the upper end surface of the driving shaft 602. An electric telescopic rod 603 is fixedly provided on the rear end surface of the No. 2 driving assembly 604, and an output end of the rear end of the electric telescopic rod 603 is fixedly connected to the auxiliary positioning tray assembly 5;

[0046] Specifically, after the pressing plate is formed, the formed PCB pressing plate can be quickly moved out from the lower end of the pressing mechanism 1 through the electric telescopic rod 603, so as to facilitate workers to take materials and reduce accidental injuries to workers caused by the pressing mechanism 1.

[0047] Reference Figure 1-Figure 2 The first drive assembly 601 includes a first housing and a first motor fixed inside the first housing, the lower end of the drive shaft 602 is fixedly connected to the output end of the first motor, and the second drive assembly 604 includes a second housing and a second motor fixed inside the second housing, and the output end of the second motor is fixedly connected to the electric telescopic rod 603;

[0048] Specifically, when the electric telescopic rod 603 is retracted and the auxiliary positioning tray assembly 5 is moved out, the No. 1 motor is first used to drive the drive shaft 602 to rotate it 90°, and then the No. 2 motor is used to drive the electric telescopic rod 603 to flip 90°, so that the opening of the auxiliary positioning tray assembly 5 faces downward and is just located on the upper end of the collection tray 7 at the lower end, so that the PCB pressing plate that has completed the pressing plate forming is poured out for collection and use.

[0049] A method for manufacturing a press plate of a PCB press plate forming and manufacturing device, specifically comprising the following steps:

[0050] Step 1. Material placement: The raw materials for the multi-layer PCB press plate molding are stacked sequentially inside the auxiliary positioning tray assembly 5, and a rubber protective layer is added on the top layer to reduce damage to the material surface caused by the press plate molding process;

[0051] Step 2. Positioning and placing: After the materials are placed, use the auxiliary collection component 6 to move the entire auxiliary positioning tray component 5 to the lower end position of the pressing mechanism 1 so that it is in a vertically corresponding position with the pressing mechanism 1;

[0052] Step 3. Pressing and forming: The hydraulic rod 2 drives the entire pressing mechanism 1 to continuously approach the upper end of the auxiliary positioning tray assembly 5 and squeeze the stacked raw materials placed inside to perform press forming. During the press plate manufacturing process, the lower surfaces of the two No. 1 pressing plates 105 will first press the entire stacked plate to form the plate, and then start the internal drive motor 104 to drive the front end gear 108 to drive the rack 103 to move, and the rack 103 drives the lower end support 1015 to move, thereby driving the No. 2 pressing plate 1010 to move laterally. In the process of the No. 2 pressing plate 1010 moving laterally, it will push the linkage rod 109 due to its action, causing the two No. 1 pressing plates 105 to move outward and translate, thereby realizing the front and rear translational extrusion and the translational extrusion on both sides of the upper surface of the stacked plate, thereby achieving the extrusion and smoothing effect of internal bubbles and other factors, thereby improving the quality of press plate forming manufacturing;

[0053] Step 4. Flip and remove the material; when the pressing plate is formed, the formed PCB pressing plate can be quickly removed from the lower end of the pressing mechanism 1 by the electric telescopic rod 603, and the entire auxiliary positioning tray assembly 5 is flipped to pour out the workpiece formed inside;

[0054] Step 5. Repeat 1-4.

[0055] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
