Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of PCB substrate polishing equipment, specifically to a fiberboard polishing device. Background Technology
[0002] PCB fiberboard typically refers to a substrate with fiberglass cloth as the reinforcing material. FR-4 is the most common PCB substrate material, made of interwoven fiberglass and epoxy resin. Fiberglass cloth substrates are sometimes also called epoxy boards, fiberboards, or fiberboards. They are made with epoxy resin as an adhesive and fiberglass cloth as a reinforcing material, and are frequently used in double-sided PCBs.
[0003] As a support for electronic components, the surface quality of fiberboard directly affects the performance and reliability of electronic products. Therefore, fiberboard polishing is an important process for improving the surface quality of PCB fiberboard substrates. It plays a crucial role in removing burrs and scratches generated during processing and improving surface roughness.
[0004] However, after prolonged use, the polishing wheels of existing fiberboard polishing machines accumulate a large amount of polishing paste residue, fiberboard debris, and other impurities on their surface. These impurities reduce the polishing efficiency and quality. Furthermore, most current polishing machines lack effective polishing wheel cleaning and cooling systems, making it impossible to clean and cool the polishing wheels in a timely manner. Manual cleaning of polishing wheels is not only inefficient but also fails to guarantee cleaning effectiveness. In addition, because the polishing wheel generates a large amount of heat during high-speed rotation, failure to cool it promptly will lead to accelerated wear and shorten its service life.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] like Figure 1 As shown, this utility model provides a fiberboard polishing device, which mainly includes a base 1, a polishing working area 2, and a polishing wheel processing assembly 4. The base 1 serves as the supporting foundation for the entire device, and the polishing working area 2 is installed on its top surface. This area is the core working area for fiberboard polishing. A housing 3 is fixed on the top surface of the polishing working area 2 to house and protect some equipment components. At the same time, the polishing wheel processing assembly 4 is also provided in the polishing working area 2 for driving, cleaning, adjusting the position of the polishing wheel 44, and cleaning residual liquid and impurities.
[0033] like Figure 2As shown, the polishing work area 2 in this embodiment specifically includes a material conveying turntable 21, which can drive several fiberboard clamps 22 fixed on it to rotate. Fiberboard is clamped inside the fiberboard clamps 22 so that the fiberboard to be polished can be sent to the polishing position in sequence. The fiberboard clamps 22 are arranged in a circular array with the center of the material conveying turntable 21 as the base point to ensure the continuity and efficiency of the polishing process. At the same time, a polishing paste delivery head 24 is fixed on the top left side of the machine base 1. Its polishing paste extrusion port is located above the fiberboard clamps 22 and is used to evenly apply polishing paste to the surface of the fiberboard during the polishing process. A polishing end head 23 is provided on the top rear side of the machine base 1. A servo electric cylinder is installed above the polishing end head 23 so that the polishing end head 23 has the ability to move up and down. The polishing drive end of the polishing end head 23 is connected to a polishing wheel 44 located above the tray 46. By moving up and down, the polishing wheel 44 can contact the fiberboard to perform the polishing operation.
[0034] like Figure 3 and Figure 4 As shown, the polishing wheel processing assembly 4 in this embodiment specifically includes components such as an electric linear guide rail 41, an electric slider 42, a booster water pump 43, a polishing wheel 44, a miniature turbofan fan 45, a tray 46, a photoelectric position sensor 47, a water tank 48, a delivery pipe 49, an atomizing nozzle 410, a branch pipe 411, and a barrier 412. The right end of the electric linear guide rail 41 is fixedly connected to the right side wall of the inner cavity of the housing 3, providing a stable sliding track for the electric slider 42. The electric slider 42 is slidably connected to the front of the electric linear guide rail 41, enabling it to drive the tray 46 fixed to its front side to move along the electric linear guide rail 41. Three to five miniature turbofan fans 45 are fixed to the left side of the inner cavity of the tray 46. The miniature turbofan fans 45... The micro turbine fan 45 is used to blow away residual cleaning fluid and impurities on the polishing wheel 44, preventing these residues from affecting the subsequent polishing effect. The air outlet of the micro turbine fan 45 is vertically oriented towards the bottom surface of the polishing wheel 44. It is turned on after the polishing wheel 44 has been cleaned or polished for a period of time, which can effectively keep the surface of the polishing wheel 44 clean. A photoelectric position sensor 47 is fixed on the left side of the inner cavity of the tray 46 to detect the position of the polishing wheel 44. After detecting the position of the polishing wheel 44, the booster water pump 43 is controlled to rinse the polishing wheel 44. After rinsing for a period of time, the booster water pump 43 stops working, and then the micro turbine fan 45 is started. The air outlet of the micro turbine fan 45 is vertical and oriented towards the bottom surface of the polishing wheel 44, which can blow away the impurities that have been cleaned.
[0035] A water tank 48 is fixed to the right side of the tray 46 and contains cleaning fluid for cleaning the polishing wheel 44. A replenishment port is provided on the outer surface of the water tank 48 for easy replenishment when the cleaning fluid is insufficient. The suction end of the booster pump 43 is connected to a flexible hose that penetrates the water tank 48 via a connector, used to extract the cleaning fluid from the water tank 48. The delivery end of the booster pump 43 is connected to a delivery pipe 49, and the end of the delivery pipe 49 is connected to a branch pipe 411 via a T-connector. Several atomizing nozzles 410 are connected to the branch pipe 411. The inlet of each atomizing nozzle 410 is connected to the branch pipe 411, and the outlet of each atomizing nozzle 410 faces the lower surface of the polishing wheel 44, used to atomize the cleaning fluid and spray it evenly onto the polishing wheel 44, achieving cleaning and cooling of the polishing wheel 44.
[0036] Working principle and usage process of this utility model:
[0037] When using this fiberboard polishing device, the fiberboard to be polished is first clamped in the fiberboard clamps 22 arranged in a circular array on the conveyor turntable 21. Then, the conveyor turntable 21 is started and begins to rotate, driving the fiberboard clamps 22 fixed on it and the fiberboard clamped therein to make a circular motion, conveying the fiberboard to the polishing paste conveying head 24 in sequence. The polishing paste conveying head 24 on the top left side of the machine base 1 starts working simultaneously. Its polishing paste extrusion port is located above the fiberboard clamps 22, extruding the polishing paste onto the fiberboard to prepare for subsequent polishing. The fiberboard with polishing paste applied continues to move to the polishing position. The polishing end head 23 fixed on the top rear side of the machine base 1 is started, driving the polishing wheel 44 located above the tray 46 to rotate. The servo electric cylinder drives the polishing wheel 44 to move downward to contact the fiberboard and perform polishing operation. After polishing is completed, the servo electric cylinder drives the polishing wheel 44 to reset.
[0038] When the polishing wheel 44 needs cleaning, the electric linear guide 41 is activated, and the electric slider 42 slides on the front of the electric linear guide 41, driving the tray 46 fixed to the front of the electric slider 42 to move. When the photoelectric position sensor 47 senses the polishing wheel 44, the tray 46 stops moving, and at this time the tray 46 reaches below the polishing wheel 44. The booster water pump 43 starts working, drawing the cleaning fluid in the water tank 48 through the hose connected to the suction end, and delivering it through the delivery pipe 49 connected to the delivery end. The end of the delivery pipe 49 away from the booster water pump 43 is connected to a branch pipe 411 through a T-connector. The branch pipe 411 is connected to the inlet of the atomizing nozzle 410. The cleaning fluid is atomized and sprayed out from the atomizing outlet of the atomizing nozzle 410, and the atomizing nozzle 410 is directed towards the polishing wheel 44. The lower surface of the polishing wheel 44 is cleaned to remove impurities and other residues left on the polishing surface during the polishing process. After a period of cleaning, the booster water pump 43 stops working, and then the micro turbo fan 45 is started. The air outlet of the micro turbo fan 45 is vertical and faces the bottom surface of the polishing wheel 44. It can not only blow away the impurities that have been cleaned, but also accelerate the air flow around the polishing wheel 44, which can cool the polishing wheel 44. The cleaning fluid during the spraying process and the cleaning fluid during the blowing process are blocked by the enclosure 412 and collected in the tray 46. The bottom of the tray 46 has a drain port, and the cleaning fluid collected in the tray 46 can be drained away by the drain pipe to prevent the cleaning fluid from splashing inside the casing 3 and contaminating other fiberboards.
[0039] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
