Description

Technical Field

[0001] The utility model mainly relates to the technical field of polishing and grinding tools, in particular to a polishing and grinding tool for automatically replacing a grinding wheel of a grinder. Background Art

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the base layer of the circuit board, which serves as the conductor of the PCB; it easily adheres to the insulating layer, accepts the printed protective layer, and forms a circuit pattern after corrosion.

[0003] During the processing of copper foil, it needs to be polished by a polishing tool. The radius of the copper foil polished by the grinding wheel on the polishing tool will be gradually shortened after a long time of polishing. In this way, the grinding wheel needs to be continuously pushed to fit the copper foil for polishing. The existing polishing tool usually pushes the grinding wheel forward by manually operating the handle, and the grinding wheel is driven forward by the manual operating handle. Since it takes a certain amount of time for the staff to react, it is difficult to react and reset the operating handle in the first time when the grinding wheel fits. This will cause the grinding wheel to fit the copper foil too tightly, which will cause damage to the copper foil. At the same time, since the copper foil is too wide, the grinding wheel usually needs a manual operating handle to drive the grinding wheel to move left and right to polish the entire copper foil. It is also difficult to keep the grinding wheel moving exactly the width of the grinding wheel each time through the manual operating handle control. In this way, if the grinding wheel moves too long, part of the copper foil will not be polished. If the grinding wheel moves too short, the number of grinding wheel movements will increase, affecting the processing efficiency. Utility Model Content

[0004] The technical solution of the utility model is aimed at the technical problem that the existing technical solution is too simple, and provides a solution that is significantly different from the existing technology. It mainly provides an automatic grinding wheel replacement polishing tool for a grinder, which is used to solve the technical problems mentioned in the above background technology that when the copper foil is polished by the polishing tool, the grinding wheel is operated to move left and right and forward and backward by manually pushing the handle. Since the staff needs time to react, manual control makes it easy for the grinding wheel to fit too closely with the copper foil when moving forward, resulting in damage to the copper foil and the grinding wheel cannot maintain a distance of one width each time the grinding wheel is moved.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A grinding wheel automatic replacement and polishing tool for a grinder comprises a first platform, a second platform and a third platform, wherein the second platform is arranged above the first platform, the third platform is arranged above the second platform, a grinding wheel for polishing copper foil is arranged above the third platform, a cylinder for driving the second platform to move horizontally left and right is arranged above the first platform, and a pushing component for driving the third platform to move forward and backward is arranged on the second platform.

[0007] Preferably, the grinding wheel is fixedly mounted on one side above the third platform, and a water spray pipe is provided on the same side of the third platform, and the water outlet of the water spray pipe is provided directly above the grinding wheel.

[0008] Preferably, a cylinder is fixedly mounted on the first platform, one end of the telescopic rod of the cylinder is fixedly connected to the second platform, a first slide rail is provided on the first platform, and the second platform is slidably connected to the second slide rail.

[0009] Preferably, the pushing assembly includes a servo motor, the servo motor is fixedly mounted above the second platform, a threaded rod is fixedly mounted on the output end of the servo motor, and the threaded rod is rotatably connected above the second platform.

[0010] Preferably, a second slide rail is arranged above the second platform, the third platform is threadedly sleeved on the threaded rod, and the third platform is slidably connected above the second slide rail.

[0011] Preferably, a driving motor is fixedly mounted above the third platform, a supporting block is fixedly mounted on a housing of the driving motor, a rotating shaft is fixedly mounted on an output end of the driving motor, and the rotating shaft is rotatably connected inside the supporting block.

[0012] Preferably, a rotating rod is rotatably connected inside the support block, a pulley group is sleeved between the rotating rod and the rotating shaft, and one end of the rotating rod is sleeved on the grinding wheel shaft.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the position of the grinding wheel is adjusted by pushing the second platform through the cylinder, and the moving distance of the second platform adjusted by the cylinder each time is set to be a distance of one width of the grinding wheel, so that the cylinder drives the grinding wheel to move horizontally every time. The problem that the manual control push rod cannot completely ensure that the moving distance is exactly one width of the grinding wheel is prevented, so that the polishing efficiency of the copper foil can be ensured, and the entire horizontal surface of the copper foil can be polished.

[0014] The servo motor cooperates with the threaded rod to drive the third platform forward to drive the grinding wheel forward. The control console is used to ensure the distance that the servo motor drives the grinding wheel to move. Such automatic movement can ensure that the grinding wheel moves forward just to fit together with the copper foil, preventing the copper foil from being moved by manual control of the handle. The manual reaction time required will cause the grinding wheel to move forward too much, which will cause damage to the copper foil. Since the copper foil is thin, the grinding wheel will affect the polishing process of the copper foil if it moves a little further. The control console controls the servo motor to automatically push the grinding wheel forward. As long as the distance between the grinding wheel and the copper foil is measured and the servo motor is set, the grinding wheel can be driven to move just the right distance.
