Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a double-sided polishing device. Background Technology

[0002] A polishing machine, also known as a polishing pad, is often used for mechanical polishing, polishing, and waxing. Its working principle is as follows: an electric motor drives a polishing disc mounted on the machine to rotate at high speed, rubbing against the surface to be polished, thereby removing paint contaminants, oxide layers, and shallow scratches.

[0003] However, existing polishing machines can only polish one side of a workpiece (such as a disc-shaped workpiece). After polishing one side, the polishing machine needs to be stopped and the workpiece needs to be flipped over to continue polishing. In addition, the existing polishing equipment generally requires manual handling of workpieces, which results in low work efficiency and increases the labor intensity of operators.

[0004] To address the aforementioned problems, this application discloses a double-sided polishing device. Utility Model Content

[0035] Example

[0036] To address the issues of low efficiency and high labor intensity associated with manual handling and flipping of disc-shaped workpieces requiring polishing on both sides in existing polishing equipment, this paper refers to... Figures 1-3 As shown, this application discloses a double-sided polishing equipment, including a machine base 10 and a loading assembly line 20 disposed above the machine base 10 for loading workpieces, a first polishing mechanism 30 for polishing one side of the workpiece, a first conveying mechanism 40 for transporting the workpieces on the loading assembly line 20 to the first polishing mechanism 30, a second polishing mechanism 50 for polishing the other side of the workpiece, a conveying and flipping conveying mechanism 60 for flipping the workpieces on the first polishing mechanism 30 and transporting them to the second polishing mechanism 50, a unloading assembly line 70 for unloading the workpieces, and a second conveying mechanism 80 for transporting the workpieces on the second polishing mechanism 50 to the unloading assembly line 70.

[0037] The feeding assembly line 20, the first polishing mechanism 30, the second polishing mechanism 50, and the unloading assembly line 70 are arranged sequentially along the first direction;

[0038] The first conveying mechanism 40 is located between the feeding line 20 and the first polishing mechanism 30;

[0039] The transport and flipping conveyor 60 is positioned between the first polishing mechanism 30 and the second polishing mechanism 50;

[0040] The second conveying mechanism 80 is located between the second polishing mechanism 50 and the unloading line 70;

[0041] Based on the above structure, the specific implementation principle is as follows: the first conveying mechanism 40 takes a workpiece from the loading line 20 and places it in the first polishing mechanism 30, and polishes one side of it through the first polishing mechanism 30. After the work is completed, the conveying and flipping conveying mechanism 60 takes the polished workpiece from the first polishing mechanism 30, flips it over and places it in the second polishing mechanism 50, and polishes the other side of it through the second polishing mechanism 50. After the work is completed, the second conveying mechanism 80 takes the workpiece in the second conveying mechanism 80 and places it on the unloading line 70 for unloading.

[0042] The first polishing mechanism 30 of this application includes a base 31 on the machine base 10, a vacuum suction cup 32 above the base 31, a first inverted L-shaped bracket 33 mounted on one side of the base 31 in the second direction, a first pneumatic slide 34 vertically mounted at the end of the horizontal part of the first inverted L-shaped bracket 33, a power motor 35 mounted on the first pneumatic slide 34, and a polishing disc 36 connected to the output shaft of the power motor 35. When the first conveying mechanism 40 picks up a workpiece from the loading line 20 and puts it into the vacuum suction cup 32, the vacuum suction cup 32 picks up the workpiece. Then, the first pneumatic slide 34 drives the power motor 35 to descend and controls the power motor 35 to drive the polishing disc 36 to rotate. When the polishing disc 36 contacts the upper surface of the workpiece, the surface of the workpiece can be polished.

[0043] Furthermore, the second polishing mechanism 50 of this application has the same structure as the first polishing mechanism 30, and the specific principle is the same as the working principle of the first polishing mechanism 30, which will not be elaborated here.

[0044] In order to synchronously drive the first conveying mechanism 40, the conveying and flipping conveying mechanism 60, and the second conveying mechanism 80, this application provides a first servo linear module 90 horizontally along its length on one side of the machine tool 10 in the second direction. The first servo linear module 90 is provided with three drive units. The first conveying mechanism 40, the conveying and flipping conveying mechanism 60, and the second conveying mechanism 80 are respectively connected to the three drive units of the first servo linear module 90. When the first servo linear module 90 is working, the first conveying mechanism 40, the conveying and flipping conveying mechanism 60, and the second conveying mechanism 80 will move along the first direction. In this way, the first conveying mechanism 40 can transport the workpiece on the loading line 20 to the first polishing mechanism 30, the conveying and flipping conveying mechanism can transport the workpiece polished by the first polishing mechanism 30 to the second polishing mechanism 50, and the second conveying mechanism 80 can transport the workpiece polished by the second polishing mechanism 50 to the unloading line 70.

[0045] Note: Before the first polishing mechanism 30 and the second polishing mechanism 50 perform polishing, the first servo linear module 90 will drive the first transport mechanism 40, the transport flipping transport mechanism 60 and the second transport mechanism 80 away from the positions of the first polishing mechanism 30 and the second polishing mechanism 50.

[0046] The first conveying mechanism 40 of this application includes a second servo linear module 41 connected to a drive unit of the first servo linear module 90, a first conveying arm 42 connected to a drive unit of the second servo linear module 41, and a first electromagnetic chuck 43 disposed at the bottom of the free end of the first conveying arm 42.

[0047] When loading the first polishing mechanism 30, the first servo linear module 90 drives the second servo linear module 41 to move to the end of the loading assembly line 20. Then, the second servo linear module 41 drives the first handling arm 42 to descend and controls the first electromagnetic chuck 43 to be energized to pick up a workpiece. After that, when the first servo linear module 90 drives the second servo linear module 41 to move to a position facing the first polishing mechanism 30, the workpiece can be placed on the vacuum chuck 32 by controlling the first electromagnetic chuck 43 to be de-energized.

[0048] The conveying and flipping mechanism 60 of this application includes a second inverted L-shaped bracket 61 connected to a drive unit of a first servo linear module 90, a second pneumatic slide 62 disposed on the transverse part of the second inverted L-shaped bracket 61, a rotary drive cylinder 63 connected below the drive unit of the second pneumatic slide 62, a rotary arm 64 connected to the output part of the rotary cylinder, a finger cylinder 65 disposed on the rotary arm 64, two finger arms 66 connected to the two drive units of the finger cylinder 65, two second electromagnetic chucks 67 respectively disposed above the two finger arms 66, a lifting cylinder 68 connected above the drive unit of the second pneumatic slide 62, a second transport arm 69 connected to the drive unit of the lifting cylinder 68, a support column 610 vertically disposed on the free end of the second transport arm 69 and corresponding to the finger cylinder 65, and a third electromagnetic chuck 611 disposed at the bottom of the support column 610.

[0049] When the first servo linear module 90 drives the second inverted L-shaped bracket 61 to move directly opposite the first polishing mechanism 30, the drive unit of the second pneumatic slide 62 performs a long-distance descent. After the descent is complete, the two finger arms 66 of the finger cylinder 65 will be positioned on both sides of the workpiece at the first polishing mechanism 30. Then, the lifting cylinder 68 drives the support column 610 to descend and pass through the middle of the two finger arms 66. When the third electromagnetic chuck 611 contacts the workpiece and is energized, it can attract the workpiece. Afterward, the lifting cylinder 68 drives the support column 610 to rise and pass the workpiece through the two finger arms 66. After the work is completed, the finger cylinder 65 drives the two finger arms 66 to move towards each other, so that the two second electromagnetic chucks 67 above the two finger arms 66 contact the bottom of the workpiece. After the two second electromagnetic chucks 67 are energized, they can attract the workpiece. After the work is completed, the third electromagnetic chuck 611 is de-energized, and the flip cylinder drives the finger cylinder 65 to flip 180° to change the surface of the workpiece. Finally, when the first servo linear module 90 drives the second inverted L-shaped bracket 61 to move to face the second polishing mechanism 50, the second electromagnetic chuck 67 is de-energized to place the changed workpiece into the second polishing mechanism 50.

[0050] Furthermore, the second conveying mechanism 80 and the first conveying mechanism 40 have the same structure, and their specific working principle is the same as that of the first conveying mechanism 40, which will not be elaborated on here.
