Technical Field

[0001] The utility model relates to the field of grinding and polishing equipment, in particular to automatic polishing equipment. Background Art

[0002] Grinding and polishing is an important process in the hardware metal processing process. However, because a large amount of sparks, dust and noise are generated during the grinding and polishing process, which seriously harms the physical and mental health of workers and the environment, grinding and polishing robots have become more and more popular and have become a major trend in grinding and polishing equipment. Generally, the hardware metal grinding and polishing process is divided into five steps: coarse sand, semi-fine sand, fine sand, rough polishing, and fine polishing. At present, the market generally adopts the method of one process corresponding to one device for processing. This processing method requires a large number of operators, and the required equipment cost is high and the labor cost is high. In addition, the workpiece to be processed is clamped repeatedly, the working process is not smooth, and the work efficiency is low. It may also cause different processing accuracy due to different clamping positions of the workpiece, and the differences are large, and the material quality is uneven.

[0003] In view of this, a Chinese patent document with the authorization announcement number CN208992410U discloses a robot grinding and polishing system, including a workbench, an operation station, a material picking station, a rough grinding station, a fine grinding station and a polishing station arranged on one side of the operation station in sequence; a material table, arranged at the material picking station of the workbench, for placing workpieces; a multi-degree-of-freedom robot, arranged at the operation station of the workbench, having a mechanical arm capable of moving between multiple stations and a fixture arranged on the mechanical arm, the fixture being used to clamp and release the workpiece, a grinding and polishing mechanism, including a first belt sander arranged at the rough grinding station, a second belt sander arranged at the fine grinding station and a polishing machine arranged at the polishing station, a control cabinet, arranged on the workbench, and electrically connected to the material table, the multi-degree-of-freedom robot and the grinding and polishing mechanism respectively. However, the system cannot adjust the polishing pressure according to the size of the material during the polishing process, which easily leads to unsatisfactory polishing effect and poor controllability.

[0004] Therefore, it is necessary to improve the above shortcomings of the prior art. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a new type of automatic polishing equipment in view of the deficiencies of the above-mentioned prior art, so as to solve the problem that the polishing pressure cannot be adjusted accordingly according to the size of the material during the polishing process, which easily leads to unsatisfactory polishing effect and poor controllability.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic polishing device, including a polishing robot and a polishing machine, the polishing machine including a polishing seat, a polishing motor installed on the polishing seat and a polishing disc rotatably connected to the output shaft of the polishing motor, the polishing seat is provided with a swing arm with one end rotatably connected to the top of the polishing seat and the other end fixedly connected to the polishing motor, and an adjustment mechanism is provided between the polishing seat and the swing arm to limit the moving distance of the polishing disc when the product to be polished contacts the polishing disc.

[0007] By adopting the above technical scheme, during polishing and grinding, after the polishing product contacts the polishing disc, the polishing disc can be pushed to drive the polishing motor, and the polishing motor drives the swing arm to rotate backward relative to the polishing seat, so that the relative distance between the polishing disc and the polishing robot is variable. The adjustment mechanism between the polishing seat and the swing arm can limit the moving distance of the polishing disc, and thus can adjust the final relative distance between the polishing disc and the material in the polishing robot during polishing, so that when polishing materials of different sizes, the appropriate polishing pressure can be adjusted accordingly to obtain the ideal polishing effect.

[0008] The above technical solution is further configured as follows: the adjustment mechanism includes an adjustment cylinder fixedly mounted on the polishing seat, the movable end of the adjustment cylinder abuts against the side of the swing arm deviating from the direction of the polishing robot and the abutment point is lower than the rotational connection point between the polishing seat and the swing arm.

[0009] By adopting the above technical scheme, when polishing operation is carried out, the manipulator of the polishing robot grabs the material onto the polishing disk, forming a backward thrust on the polishing disk, thereby driving the polishing motor and the swing arm to swing backward relative to the connection point with the polishing seat, so that the swing arm abuts against the active end of the adjusting cylinder and stops swinging, and the polishing pressure stabilizes at this time; when the polishing pressure needs to be adjusted for polishing materials of different sizes, the active end of the adjusting cylinder is extended and retracted to adjust the relative distance between the polishing disk and the polishing robot during polishing, so that the pressure between the polishing disk and the material can be controlled and adjusted.

[0010] The above technical solution is further configured as follows: a limit stopper is provided on the side of the swing arm close to the polishing robot, and the contact surface between the limit stopper and the swing arm is in a vertical direction.

[0011] By adopting the above technical solution, the limit block can limit the swing arm from swinging toward the polishing robot, which can avoid excessive swing amplitude and make the position of the polishing plate relatively stable; the limit block can make the swing arm stop in the vertical direction of natural hanging.

[0012] The above technical solution is further configured as follows: a rotating shaft is provided on the top of the polishing seat, and a rotating shaft hole that matches the rotating shaft clearance is provided at one end of the swing arm that deviates from the polishing plate.

[0013] By adopting the above technical solution, the swing arm can rotate around the rotating shaft on the polishing seat through the clearance fit between the rotating shaft and the rotating shaft hole.

[0014] The above technical solution is further configured as follows: the automatic polishing equipment also includes a control cabinet, the control cabinet is electrically connected to the polishing robot and the polishing machine respectively, and the regulating cylinder is externally connected to an air source whose air pressure is controlled by a control cabinet program.

[0015] By adopting the above technical solution, the polishing robot and the polishing machine can be controlled to work automatically in coordination through the control cabinet, and the air pressure of the cylinder air source can be adjusted by automatic program control to adjust the extension and retraction of the movable end of the cylinder, thereby realizing automatic control of the polishing pressure, which is more efficient than manual adjustment.

[0016] The above technical solution is further configured as follows: an arc-shaped dust baffle is provided on the side of the polishing disc deviating from the polishing robot, the dust baffle is fixedly mounted on the swing arm, and a dust collecting port is provided at the lower end of the dust baffle.

[0017] By adopting the above technical solution, during the polishing process, the dust baffle can block part of the dust inside the baffle and drop it to the dust collecting port, which is convenient for dust collection and thus reduces dust pollution.

[0018] The above technical solution is further configured as follows: an opening and closing plate is provided on a side of the dustproof baffle that deviates from the swing arm and is rotatably connected to the dustproof baffle outward, and a locking mechanism is provided between the opening and closing plate and the dustproof baffle.

[0019] By adopting the above technical solution, when the polishing disc needs to be replaced, the locking mechanism can be unlocked, and then the opening and closing plate can be rotated outward to conveniently replace the polishing disc; after the replacement is completed, the opening and closing plate is closed, and then the locking mechanism is locked to continue the polishing work.

[0020] The above technical solution is further configured as follows: the automatic polishing equipment also includes a material table for facilitating the polishing robot to grab materials, and the material table is provided with a first rack for placing materials to be polished and a second rack for placing polished materials.

[0021] By adopting the above technical solution, the first rack on the material table is used to place the material to be polished, and the second rack is used to place the polished material, which can reduce the waiting time for material replacement and improve the polishing work efficiency.

[0022] The above technical solution is further configured as follows: the automatic polishing equipment also includes a workbench, and the control cabinet, the polishing machine and the material table are all installed on the workbench.

[0023] By adopting the above technical solution and setting up a workbench, the positions of the polishing robot, the control cabinet, the polishing machine and the material table can be relatively stable, and unified transportation is convenient.

[0024] The above technical solution is further configured as follows: a dust cover is provided on the workbench, the polishing robot, control cabinet, polishing machine and material table are all located in the dust cover, a material changing window is provided on a side of the dust cover close to the material table, and the polishing robot is installed on the top of the dust cover.

[0025] By adopting the above technical solution, a dust cover is set on the workbench to limit the polishing area to a limited space, which can avoid dust to a certain extent and pollute the surrounding environment; during polishing, the material changing window on the dust cover cooperates with the external material changing equipment to discharge and take materials from the material table.

[0026] The beneficial effect achieved by the utility model is that during the polishing process, the distance between the polishing disc and the polishing manipulator can be automatically adjusted by program control according to the size of the material to adapt to the corresponding polishing pressure, thereby achieving an ideal polishing effect.
