Description

Technical Field

[0001] This invention relates to reciprocating razors, and more particularly to a blade polishing device for reciprocating razors. Background Technology

[0002] A reciprocating shaver is a common personal care appliance that uses a set of working blades to shave facial hair. The fixed blade and the movable blade are two key components of a reciprocating shaver. The fixed blade is usually fixed behind a metal mesh, while the movable blade is a set of blades that can move back and forth below the fixed blade. When the shaver is turned on, the movable blade moves rapidly back and forth below the fixed blade, thus shaving the hair.

[0003] Reciprocating razors have two blades: a fixed blade and a movable blade. For example... Figure 16 and Figure 17 As shown, both the fixed blade and the movable blade are elongated U-shaped structures, with their cutting edges located at the flange of the U-shaped structure opening.

[0004] During the manufacturing process, burrs are generated on the blades of both the fixed and movable razors due to machining. These burrs not only affect shaving comfort and performance but can also potentially scratch the user's skin. Therefore, removing these burrs is a crucial process step. The deburring process for the fixed and movable blades of a razor requires particular precision because these parts are relatively fragile and directly impact shaving results. Grinding or polishing methods are typically used to remove burrs from the fixed and movable blades, ensuring smooth, burr-free blade edges. Traditional manual deburring and polishing processes are not only inefficient but also produce inconsistent polishing quality. Summary of the Invention

The sliders 722 of the two sets of fifth linear guide pairs 72 are respectively connected to the belts 751 on both sides of the synchronous belt device 75 along the X-axis through belt clamps 76. The synchronous belt device 75 drives the two receiving boxes 71 to alternately move from the receiving position to the unloading position or return from the unloading position to the receiving position.

[0060] Although the feeding mechanism 20 of the reciprocating shaver blade polishing device in the above embodiments of the present invention has two vibrating discs 21 and the feeding mechanism 100 has two dispensing devices 40, which can be used for feeding and dispensing the movable blade 01A or for feeding and dispensing the fixed blade 01B, when the blade polishing device is working, only one vibrating disc 21 and the corresponding dispensing device 40 can be selected to work, that is, only feeding and dispensing the movable blade 01A or only feeding and dispensing the fixed blade 01B.

[0061] The working process of the blade polishing device for the reciprocating shaver according to the above embodiments of the present invention includes the following steps:

[0062] 1) Vibratory feeder 21 outputs workpiece 01 to be processed to the corresponding material distribution device 40 through material conveying trough 23. Workpiece 01 is conveyed to the receiving trough 45 of the corresponding material distribution block 41, with the opening of workpiece 01 facing upward.

[0063] 2) The material distribution cylinder 43 moves the material distribution block 41 from the loading position to the unloading position;

[0064] 3) The first Z-axis motion mechanism of the workpiece flipping device 30 drives the rotary cylinder 32 and the first gripper cylinder 31 to move downward. After the gripper of the first gripper cylinder 31 clamps the workpiece 01, the first Z-axis motion mechanism drives the rotary cylinder 32 and the first gripper cylinder 31 to move upward and reset.

[0065] 4) The rotary cylinder 32 drives the first gripper cylinder 31 and the workpiece 01 to rotate 180°, with the gripper of the first gripper cylinder 31 and the workpiece 01 facing upwards; the Y-axis motion mechanism moves the first gripper cylinder 31 from the pick-up position to the unload position.

[0066] 5) The second gripper cylinder 84A of the first workpiece transfer device 81A moves to the unloading position of the workpiece flipping device 30, and the gripper of the second gripper cylinder 84A clamps the workpiece 01 in the gripper of the first gripper cylinder 31; the second Z-axis direction motion mechanism 83 of the first workpiece transfer device 81A lifts the second gripper cylinder 84A and the clamped workpiece 01.

[0067] 6) The first linear module 82 of the first workpiece transfer device 81A moves the second gripper cylinder 84A and the gripped workpiece 01 along the X-axis direction above a set of workpiece clamping and feeding mechanism 60. At this time, the polishing fixture 60B corresponding to the workpiece clamping and feeding mechanism 60 is in the loading position.

[0068] 7) Based on the length of workpiece 01, the fixture selection device of polishing fixture 60B adjusts the position of workpiece fixture 60C along the Y-axis direction, and selects one of the workpiece fixtures 60C as the working fixture to carry the workpiece 01 to be processed.

[0069] 8) The second Z-axis motion mechanism 83 of the first workpiece transfer device 81A drives the second gripper cylinder 84A and the gripped workpiece 01 to descend. The second gripper cylinder 84A places the gripped workpiece 01 onto the workpiece fixture 60C, which serves as a working fixture. The U-shaped groove of the workpiece 01 is fastened to the elastic support piece 631 of the workpiece fixture 60C. The fingers of the finger cylinder 63 of the workpiece fixture 60C close, and the two elastic clamping pieces 632 on the fingers of the finger cylinder 63 clamp the workpiece 01. The second gripper cylinder 84A releases the workpiece 01, and the first workpiece transfer device 81A resets.

[0070] 9) The Y-direction linear module 62 of the polishing feed mechanism 60A moves the polishing fixture 60B to the polishing position. The workpiece fixture 60C and the workpiece 01, which serve as working fixtures, are located between the polishing wheels of the two polishing machines 51 of the corresponding polishing mechanism 50.

[0071] 10) When polishing workpiece 01, the reciprocating swing mechanism 60D swings with the work fixture, and the X-direction linear module 61 of the polishing feed mechanism 60A moves between the polishing wheels of the two polishing machines 51 with the work fixture, so that all the parts of workpiece 01 that need to be polished are polished.

[0072] 11) After the workpiece 01 is polished, the first linear module 82 of the second workpiece transfer device 81B moves the second gripper cylinder 84B above the finished workpiece 01 along the X-axis direction. The second Z-axis motion mechanism 83 of the second workpiece transfer device 81B drives the second gripper cylinder 84B to descend. The second gripper cylinder 84B grips the finished workpiece 01, and the workpiece fixture 60C releases the finished workpiece 01.

[0073] 12) The Y-direction linear module 62 of the polishing feed mechanism 60A moves in the opposite direction and resets with the polishing fixture 60B;

[0074] 13) The second workpiece transfer device 81B transfers the completed workpiece 01 to the receiving box 71 in the receiving position of the unloading mechanism 70. After the receiving box 71 in the receiving position is full, the synchronous belt device 75 starts and moves the receiving box 71 in the receiving position to the unloading position to unload the workpiece. The empty receiving box 71 moves to the receiving position to receive the workpiece at the same time.

[0075] The blade polishing equipment of the present invention described above can automatically polish the fixed blades and movable blades of a reciprocating shaver, with high polishing and deburring efficiency, stable polishing quality, and low labor intensity for operators.
