A copper-clad plate cooling device

Abstract

This utility model discloses a copper-clad laminate (CCL) cooling device, which includes a cooling box and a conveying roller. The CCL is placed into the upper end of the conveying roller inside the cooling box through an inlet plate. Under the action of the side protrusions, the CCL is lifted up. Then, the motor drives the transmission rod, which in turn drives the transmission gear through the drive gear, causing the rotating shaft to rotate the internal conveying roller in the same direction, so that the CCL moves to one side. During the movement, the first fan delivers gas to the conveying roller through the airflow main pipe and the ventilation pipe, and blows air to cool the bottom end of the CCL under the air groove during rotation. Moreover, the second motor at the top and the top air pipe can blow air to the lower end, thereby achieving air blowing cooling of both the upper and lower ends of the CCL, avoiding the situation of poor cooling effect on one side. This cooling method can also avoid the low efficiency of natural cooling, making the working efficiency higher.

Description

Technical Field

[0001] This utility model relates to the technical field of copper clad laminate processing equipment, and in particular to a copper clad laminate cold plate device. Background Technology

[0002] Copper-clad laminate, also known as copper foil laminate, is a sheet material made by impregnating electronic fiberglass cloth or other reinforcing materials with resin, covering one or both sides with copper foil, and then hot-pressing them. Various types and functions of printed circuit boards are manufactured by selectively processing, etching, drilling, and copper plating on the copper-clad laminate. The copper-clad laminate primarily serves to interconnect, insulate, and support printed circuits, significantly influencing signal transmission speed, energy loss, and characteristic impedance.

[0003] Furthermore, copper clad laminates require cooling during the production and processing process, but most of them are currently cooled naturally, which is inefficient. Alternatively, they are transported by conveyor belt and air is blown on top of them, but air cooling is mostly done on one side, resulting in a temperature difference between the two sides and affecting the cooling effect.

[0004] Therefore, a copper-clad laminate cold plate device is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To overcome the shortcomings of existing technologies, a copper-clad laminate cooling plate device is proposed to solve the problems of low cooling efficiency and poor cooling effect of current copper-clad laminates.

[0007] (II) Technical Solution

[0008] This utility model is achieved through the following technical solution: This utility model proposes a copper-clad laminate cold plate device, including a cooling box.

[0009] The cooling box has several conveyor rollers with internal cavities installed side by side and rotating inside. The conveyor rollers are connected to rotating shafts that pass through their interiors on both sides. The outer side of the rotating shafts is connected to the cooling box via bearings. A side box is installed on one side of the cooling box, and a gear drive assembly is installed inside the side box and connected to the rotating shaft on the inner side.

[0010] The outer side of the conveying roller is provided with several side protrusions, and air grooves that penetrate the internal cavity are provided between the side protrusions.

[0011] A first fan is installed on one side of the cooling box. The air supply end of the first fan is connected to the airflow main pipe. The inside of the rotating shaft is rotatably connected to the air pipe through the bearing, and the air pipe is connected to the airflow main pipe.

[0012] Furthermore, an entry plate and a placement plate are respectively installed at the openings on the left and right ends of the cooling box, located at the horizontal plane of the conveyor roller.

[0013] Furthermore, the gear drive assembly includes a transmission rod rotatably mounted inside the side box.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] 1. In this utility model, the first fan blows air through the airflow main pipe and the vent pipe through the air groove outside the conveying roller, while the second fan blows the air downwards through the top air pipe and the jet nozzle, thereby achieving the blowing and cooling of the copper-clad laminate, avoiding the low efficiency of natural cooling and achieving a faster cooling rate.

[0020] 2. In this utility model, the motor drives the transmission rod to rotate the conveyor roller under the action of the drive gear and the transmission gear, thereby pushing the copper-clad laminate to one side under the action of the side protrusion. During the pushing process, the air groove blows air onto the bottom surface of the copper-clad laminate, and the air pipe at the top realizes the air blowing and cooling of the upper and lower surfaces of the copper-clad laminate.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] Please see Figures 1-5 This utility model provides a copper-clad laminate cooling device, including a cooling box 1, which cools the copper-clad laminate inside. An entry plate 2 and a placement plate 3 are respectively installed at the left and right openings of the cooling box 1 at the horizontal plane of the conveyor roller 9. The entry plate 2 facilitates placement and storage when the laminate enters the cooling box 1, while the placement plate 3 facilitates storage after cooling, allowing for easy organization and tidying by staff. A controller 4 and a transparent observation window are installed on the outer front of the cooling box 1. The externally purchased controller 4 facilitates operation of the electrical components in the device, making operation more convenient. The transparent observation window allows for observation of the movement of the copper-clad laminate inside, further facilitating operation. A front plate 17 is located above the entry plate 2 at the front of the cooling box 1, and a third fan 18 is installed inside the front plate 17. The third fan 18 allows exhaust to one side after cooling, thus expelling the hot air generated during the cooling process to the other end, accelerating the cooling effect and improving its efficiency.

[0030] Inside the cooling box 1, several conveyor rollers 9 with internal cavities are installed side-by-side and rotate. The rotation of the conveyor rollers 9 moves the copper-clad laminate (CCL) within the cooling box 1. Several side protrusions 12 are provided on the outer side of the conveyor rollers 9. These side protrusions 12 are made of high-temperature resistant rubber material to enhance friction and improve the pushing effect. Air grooves 13 penetrate the internal cavities between the side protrusions 12, allowing the CCL to be lifted by the side protrusions 12, creating a distance between them and the air grooves 13. This allows air to blow onto the bottom surface of the CCL from within the air grooves 13. Rotating shafts 10 are connected to both sides of the conveyor rollers 9, penetrating their internal cavities for ventilation. However, the rotating shafts 10 inside the side chamber 5 are enclosed to prevent air from escaping from one side. The outer side of the rotating shafts 10 is connected to the cooling box 1 via bearings, allowing the conveyor rollers 9 to rotate. The cooling box 1... A side box 5 is installed on the side, and a gear drive assembly is installed inside the side box 5 and connected to the inner rotating shaft 10. The gear drive assembly includes a transmission rod 19 rotatably installed inside the side box 5. The rotating shaft 10 passes through the inside of the side box 5 and is connected to transmission gears 112. The transmission rod 19 has several drive gears 111 meshing with the transmission gears 112 to form a bevel gear structure. A motor 110 is installed at one end of the outer side of the side box 5, and the output end of the motor 110 is connected to the transmission rod 19. Thus, the rotation of the transmission rod 19 driven by the motor 110 causes the drive gears 111 to rotate. The drive gears 111 drive the transmission gears 112 to rotate the rotating shaft 10 and the conveyor roller 9, so that the conveyor roller 9 rotates in the same direction. This rotation of the conveyor roller 9 pushes the copper-clad laminate, allowing it to move and be cooled inside the cooling box 1. The conveyor roller 9 moves and feeds simultaneously, resulting in higher working efficiency.

[0031] A first fan 6 is installed on one side of the cooling box 1. The air supply end of the first fan 6 is connected to the airflow main pipe 8. The inside of the rotating shaft 10 is rotatably connected to the air pipe 11 through bearings. This rotatable connection can avoid interference during the rotation of the conveyor roller 9. The air pipe 11 runs through and connects to the airflow main pipe 8. The air generated by the first fan 6 is input into the interior of the conveyor roller 9 through the first fan 6 and the air pipe 11 via the rotating shaft 10, and discharged outward through the air groove 13, thereby achieving air blowing cooling of the bottom surface. The cooling box 1 is equipped with a hanging plate 14 at the top and a row of top air pipes 15 at the bottom. The bottom of the top air pipes 15 is equipped with several air jets 16. A second fan 7 is installed at the top of the cooling box 1, and the output end of the second fan 7 is connected to the top air pipes 15. Air is supplied through the top air pipes 15 of the cooling box 1 and exhausted downward through the air jets 16, so that it can blow air to cool the upper surface of the copper-clad board, thereby realizing the blowing air cooling of the upper and lower surfaces and making the cooling effect better.

[0032] Working principle: In use, first connect the first fan 6, the second fan 7, the third fan 18, the motor 110, and the controller 4 to an external power source. Then, place the copper-clad laminate into the cooling box 1 through the inlet plate 2. The motor 110 drives the transmission rod 19, which drives the rotating shaft 10 through the drive gear 111 and the transmission gear 112, causing the inner conveying roller 9 to rotate to the same side. This pushes the copper-clad laminate to the box placement plate 3. During the movement, the copper-clad laminate has a gap at its bottom end due to the action of the side protrusion 12. Then, the first fan 6 delivers air to the inside of the conveying roller 9 through the air main pipe 8 and the vent pipe 11, and discharges it through the air groove 13 to blow air onto the bottom end of the copper-clad laminate. The second fan 7 blows air onto the upper end of the copper-clad laminate through the top air pipe 15 and the jet nozzle 16. This achieves air blowing and cooling of both the upper and lower ends, resulting in better cooling effect. After cooling, the third fan 18 can be started to exhaust air according to the internal conditions, thus completing the work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
