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 cleaning equipment. Background Technology

[0002] Copper-clad laminate (CCL) is a fundamental material in the electronics industry, primarily used in the manufacture of printed circuit boards (PCBs). It is made by impregnating reinforcing materials such as wood pulp paper or fiberglass cloth with resin, covering one or both sides with copper foil, and then hot-pressing them together. It is widely used in electronic products such as televisions, radios, computers, and mobile communications equipment, and is a core material in PCB manufacturing. During the production process, contaminants and oxides on the substrate surface need to be cleaned to ensure smooth subsequent processing and product quality.

[0003] However, copper-clad laminates are mostly cleaned by conveying them on a conveyor belt, cleaning one side, and then turning them over for cleaning. This method has low cleaning efficiency. Alternatively, they can be piled up and cleaned with ultrasonic waves, but this method is prone to damage and the cleaning effect is not good.

[0004] Therefore, a double-sided cleaning equipment for copper-clad laminates is proposed. Utility Model Content

Detailed Implementation

[0029] 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.

[0030] Please see Figures 1-5 This utility model provides a copper-clad laminate cleaning device, including a cleaning tank 1, which cleans the copper-clad laminate inside, reducing the leakage of cleaning solution. An observation window 2 and a controller 4 are installed on the outside of the cleaning tank 1. The externally purchased controller 4 facilitates the operation of the electrical components in the device, making operation more convenient. The observation window 2 allows for easy observation of the internal cleaning status. A central partition 12 is laid inside the cleaning tank 1, and a protruding plate is provided between the central partition 12 and the cleaning tank 1 at the mounting plate 16 and the lifting frame 119, thereby reducing liquid splashing to the sides. Inlet and outlet 6 are provided on the upper ends of both sides of the central partition 12 to allow the copper-clad laminate to enter and exit. Placement plates 7 are provided on both sides of the inlet and outlet 6 to facilitate placing the copper-clad laminate on them, making it easier for operators to retrieve it. A water storage chamber is provided at the bottom of the cleaning tank 1 for holding the cleaning solution. A pump body 113 is installed on the outside of the cleaning tank 1 via a pump box 112. The output end of pump 113 is connected to the bottom water pipe 13 and the top water pipe 19 through the diversion pipe 114. Under the action of pump body 113, the cleaning liquid inside the water storage chamber is easily sucked out and fed into the bottom water pipe 13 and the top water pipe 19 for spray washing. The middle partition 12 is provided with a trough that runs through the upper and lower ends to facilitate the downward flow of the liquid after spray washing. The filter layer 116 is slidably installed inside the lower water storage chamber through the installation step 115, so that the filter layer 116 can be easily disassembled. The filter layer 116 can be composed of an outer frame and an internal filter material. The filter material can be replaced and can be composed of filter screens or adsorbent carbon. The suction end of pump body 113 runs through the inside of the water storage chamber, so that the filtered water can be recycled to save resources. The bottom of the water storage chamber is provided with a water exchange port 5 to facilitate the addition and replacement of the cleaning liquid inside. The outside of the cleaning tank 1 is provided with a side door 3 located at the filter layer 116, so that the filter layer 116 can be taken out for cleaning or replacement.

[0031] A transmission box 8 is located on one side inside the cleaning tank 1 to prevent liquid from affecting its internal structure. Several rotating rollers 117 are rotatably mounted between the transmission box 8 and the cleaning tank 1, allowing the copper-clad laminate to be pushed during rotation. The rotating rollers 117 are spaced apart. A bottom water pipe 13 is located at the upper end of the middle partition 12. Bottom spray nozzles 14 are connected to both ends of the bottom water pipe 13 and are located at intervals on both sides of the rotating rollers 117. This allows the copper-clad laminate to be sprayed and washed from both sides, and then sprayed and washed again after cleaning to ensure the surface of the copper-clad laminate is clean. For better cleaning results, several bottom nozzles 15 are provided at the upper end of the bottom spray outlet 14 to clean the upward-sprayed cleaning solution. A cleaning brush roller 18 is rotatably mounted at intervals in the middle of the rotating roller 117. Cleaning brushes on the outer side of the cleaning brush roller 18 clean the surface of the copper-clad laminate, preventing incomplete cleaning. A gear drive mechanism is installed inside the transmission box 8, connected to the rotating roller 117 and the cleaning brush roller 18, causing the rotating roller 117 to rotate and the cleaning brush roller 18 to rotate, resulting in better cleaning force. A mounting plate 1 is provided at the upper end of the cleaning box 1. 6. A top water pipe 19 is installed at the lower end of the mounting plate 16. Top spray nozzles 110 are provided on both sides of the top water pipe 19, corresponding to the bottom spray nozzles 14. The bottom surface of the top spray nozzles 110 is provided with several top nozzles 111, so that the upper and lower ends of the copper-clad laminate are sprayed and cleaned respectively, thereby improving the cleaning effect and avoiding the low efficiency of cleaning only one side. A fixed plate 17 is provided in the middle of the mounting plate 16, on which a cleaning brush roller 18 is rotatably mounted, which also cleans the upper surface of the copper-clad laminate. A second motor 125 is installed on the outside of the fixed plate 17 and is connected to the cleaning brush roller 18. The brush roller 18 is connected so that the upper cleaning brush roller 18 can rotate faster under the drive of the second motor 125, and it is also convenient to strengthen the pushing work of the copper-clad board during the cleaning process. A first electric push rod 9 is installed at the top of the cleaning box 1, and the output end of the first electric push rod 9 passes through the cleaning box 1 and is connected to the mounting plate 16. When the first electric push rod 9 pulls the mounting plate 16 up and down, the distance between the top nozzle 111 and the upper cleaning brush roller 18 and the copper-clad board is changed, so as to realize the cleaning work of different copper-clad boards and make the working effect better.

[0032] On the other side of the cleaning tank 1, at the same horizontal plane as the rotating roller 117, a bottom adsorption roller 118 is rotatably installed. A lifting frame 119 is provided at the top of the cleaning tank 1, and a top adsorption roller 120 is rotatably installed inside the lifting frame 119, corresponding to the bottom adsorption roller 118. This allows the adsorption cotton on the outside of the bottom adsorption roller 118 and the top adsorption roller 120 to adsorb the liquid on the upper and lower ends of the copper-clad laminate when it rotates inside, thereby reducing the liquid on its surface and improving the subsequent drying effect. A second electric push rod 10 is provided at the top of the bottom adsorption roller 118, and the output end of the second electric push rod 10 passes through the cleaning tank 1 and is connected to the lifting frame 119. The second electric push rod 110 drives the lifting frame 119 to adjust the height of the top adsorption roller 120, thereby cleaning different copper-clad laminates.

[0033] Preferably, a number of telescopic rods 11 are installed at the top of the cleaning tank 1 and are respectively connected to the mounting plate 16 and the lifting frame 119. The telescopic rods 11 enhance the stability of the mounting plate 16 and the lifting frame 119, resulting in better stability.

[0034] The gear drive mechanism includes a transmission rod 121 rotatably disposed inside the transmission box 8. A first motor 124 is installed on the outside of the transmission box 8 and connected to the transmission rod 121. The rotating roller 117, the bottom suction roller 118, and the bottom cleaning brush roller 18 are all equipped with transmission gears 123 through the inner side of the transmission box 8. The transmission rod 121 has several drive gears 122 meshing with the transmission gears 123 to form a bevel gear structure. When the first motor 124 drives the transmission rod 121 to rotate, the drive gears 122 rotate, which in turn drive the transmission gears 123, causing the rotating roller 117, the bottom suction roller 118, and the bottom cleaning brush roller 18 to rotate. This rotation pushes the copper-clad laminate for cleaning, avoiding manual pushing and making the work more efficient.

[0035] Working principle: In use, first connect the first electric push rod 9, the second electric push rod 10, the pump body 113, the first motor 124, the second motor 125 to the controller 4 and connect them to an external power supply. Then, place the copper-clad laminate on the upper end of the rotating roller 117 through the placement plate 7 on the outside of the inlet and outlet 6. When the rotating roller 117 rotates and pushes the copper-clad laminate to move, the first electric push rod 9 and the second electric push rod 10 cause the mounting plate 16 and the lifting frame 119 to make the cleaning brush roller 18 and the top suction roller 120 contact the copper-clad laminate downwards. As the copper-clad laminate moves... During the process, the pump body 113 uses the diversion pipe 114 to allow the liquid inside the water storage chamber to enter the bottom water pipe 13 and the top water pipe 19. The liquid then passes through the top nozzle 111 and the bottom nozzle 15 to spray and wash the surface of the copper-clad laminate. The cleaning brush roller 18 also rotates to clean the surface of the copper-clad laminate. The liquid that falls off during cleaning falls downwards and is filtered through the filter layer 116 before being recycled. After spraying, the liquid enters between the bottom adsorption roller 118 and the top adsorption roller 120, where it is adsorbed by the adsorption layer on its surface and then discharged to complete the cleaning 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.
