Description

Technical Field

[0001] The utility model relates to the technical field of circuit board manufacturing equipment, in particular to a circuit board cold press. Background Art

[0002] As we all know, PCBs, also known as circuit boards or printed circuit boards, are important electronic components. They also support electronic components and provide circuit connections for them. Numerous electronic components can be integrated on them and electrically connected through copper-clad circuits. Therefore, during the PCB production process, one step involves pressing the copper foil, which acts as a conductor, onto the PCB's resin substrate. This process utilizes a PCB cold press.

[0003] Currently, existing cold presses for circuit boards, compared to hot presses, rely on the pushing force of a hydraulic cylinder and an internally installed electrical plug to conduct electricity with the copper foil, causing the copper foil to heat up when it is energized. The copper foil is then hot-pressed to the board. The equipment's push plate does not generate heat, and the equipment is equipped with a cooling component to prevent the heat from the copper foil from being retained and transferred within the equipment. However, most existing cold presses can only press one group at a time, resulting in low work efficiency. Furthermore, most existing cooling components rely solely on cooling fans for heat dissipation, which has limited heat dissipation and cannot quickly and stably cool the pressed boards.

[0004] Therefore, the existing circuit board cold press needs to be technically optimized and improved. Utility Model Content

[0011] Preferably, the chassis is provided with a partition cavity at the fan, and the outer shell of the chassis is provided with a heat dissipation hole communicating with the partition cavity.

[0025] like Figures 1 to 6As shown, a circuit board cold press provided in this embodiment includes a chassis 1 and an inner frame 2 arranged inside the chassis 1, a processing chamber 3 is provided in the inner frame 2, and a partition 4 is set up in the processing chamber 3. The processing chamber 3 is divided into an upper chamber and a lower chamber by the partition 4, and the bottom and top of the processing chamber 3 are provided with an upper push plate 6 and a lower press plate 7 that can slide up and down along the guide column 5 through a guide column 5. The upper end surface of the partition 4 and the upper surface of the upper push plate 6 are both provided with a conductive seat 8 for energizing the copper foil, and at least one first liquid is provided on the inner frame 2. The pressure cylinder 9 and at least one second hydraulic cylinder 10, the pushing head of the first hydraulic cylinder 9 is mechanically connected to the upper push plate 6, the pushing head of the second hydraulic cylinder 10 is mechanically connected to the lower pressure plate 7, the upper end face and the lower end face of the partition 4, the surface of the upper push plate 6 and the surface of the lower pressure plate 7 are all embedded with water cooling pipes 11, and the inner frame 2 is provided with a water inlet pipe 12 and a drain pipe 13, the water inlet of the water cooling pipe 11 is connected to the water inlet pipe 12 through a hose 14, and the water outlet of the water cooling pipe 11 is connected to the drain pipe 13 through a hose 14.

[0026] The functional principle of this embodiment mainly relies on the establishment of an upper push plate 6 and a lower pressure plate 7 for pressing the sheet materials at the upper and lower parts of the processing chamber 3 respectively. Combined with the establishment of the partition 4, two groups of sheet materials can be pressed at the same time, which effectively improves the processing efficiency. At the same time, water cooling pipes 11 are set on the partition 4 and the upper push plate 6 and the lower pressure plate 7. Relying on the water cooling heat dissipation principle, the heat dissipation effect can be greatly improved.

[0027] During the specific operation, the two sets of sheet materials 100 that need to be pressed together are pushed into the upper push plate 6 and the upper surface of the partition 4 from the feeding port of the processing chamber 3. When all the sheet material groups 100 are pushed in, the copper foil on the sheet material group 100 will be connected to the conductive seat 8, and then the pressing work can be started. During pressing, the first hydraulic cylinder 9 pushes the upper push plate 6 upward, and the second hydraulic cylinder 10 pulls the lower pressure plate 7 downward, and finally the upper and lower end surfaces of the partition 4 respectively receive the other end of the sheet material group 100. As the first hydraulic cylinder 9 and the second hydraulic cylinder 10 continue to apply force, the sheet material group 100 is gradually pressed together. During pressing, electricity will be turned on to make the copper foil energized and heated to complete the pressing between the copper foil and the sheet material. When the pressing is completed, the water cooling system can be turned on, that is, the external water pump is turned on to discharge water into the water inlet pipe 12. The water passes through the water cooling pipe 11 and is discharged from the drain pipe 13. In this way, the heat can be gradually taken away by the flow of water, thereby achieving the effect of heat dissipation and cooling the sheet metal after the die-casting is completed.

[0028] Furthermore, in order to maximize the water cooling effect, the water cooling pipelines 11 of this embodiment are arranged in an "S" shape.

[0029] Furthermore, to enhance heat dissipation, the inner frame 2 of this embodiment is evenly distributed with fans 15 on the inner wall of the processing chamber 3. The chassis 1 is provided with compartments 16 located near the fans 15, and the outer shell of the chassis 1 is provided with heat dissipation holes 17 that communicate with the compartments 16. The fans 15 exhaust air from the processing chamber 3 and introduce external air, thereby achieving air conduction between the inside and outside of the processing chamber 3. The principle is that one group of fans 15 exhausts air outward, while another group of fans 15 exhausts air inward. Furthermore, to reduce the size of the equipment, the fans 15 of this embodiment are cross-flow fans, so that a single cross-flow fan can guide air across a larger area.

[0030] Furthermore, regarding the specific structure of the conductive seat 8, the conductive seat 8 of this embodiment includes a base 81 and an electrical contact 82 provided on the sheet assembly 100. The electrical contact 82 is located on the side of the sheet assembly 100. The base 81 is respectively mounted on the partition 4 and the upper push plate 6. The base 81 is provided with a cylinder 83. The pushing head of the cylinder 83 is provided with an electrical plug 84 corresponding to the electrical contact 82. The electrical plug 84 is connected to an external power source. Therefore, after the sheet assembly 100 is pushed in, the cylinder 83 will start to work, connecting the electrical contact 82 with the electrical plug 84. The electrical plug 84 can use a spring-loaded ejector pin. However, the sheet assembly 100 itself is relatively heavy, and the driving force of the selected cylinder 83 must be less than the weight of the sheet assembly 100, that is, the cylinder cannot push the sheet assembly 100.

[0031] Furthermore, in order to facilitate guiding and limiting when pushing in the sheet material group 100, the upper end surfaces of the upper push plate 6 and the partition 4 of this embodiment are both provided with first guide rollers 18 on both sides, and the front ends of the upper end surfaces of the upper push plate 6 and the partition 4 are provided with second guide rollers 19, and the rear ends of the upper end surfaces of the upper push plate 6 and the partition 4 are provided with limiting blocks 20, and the limiting blocks 20 are provided on the upper push plate 6 and the partition 4, or the limiting blocks 20 are provided on the base 81, wherein after the sheet material group 100 is pushed in, positioning can be performed by relying on the first guide rollers 18 and the limiting blocks 20.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
