Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and more particularly to a surgical blade circulating polishing device. Background Technology

[0002] A scalpel is a specialized surgical instrument consisting of a blade and a handle, used for cutting human or animal tissues. It is an indispensable and important surgical tool. The blade typically has a cutting edge and a mounting hole for connecting with the handle, and is usually made of pure titanium, titanium alloy, stainless steel, or carbon steel.

[0003] During the production of blades, the cutting edge needs to be ground, and the ground edge will have burrs, thus requiring polishing. Currently, most polishing methods use manual polishing, where an operator holds a sheet of blades, fans them out like playing cards, and places them directly on a polishing wheel for polishing. This traditional polishing method is extremely time-consuming and labor-intensive, significantly reducing work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a cyclic polishing device for surgical blades, which replaces traditional manual polishing with automatic machine polishing, saving considerable time and effort and greatly improving work efficiency, thereby solving the problems mentioned in the background art.

The circulating conveying mechanism includes a worktable with a circulating track connected to it. A circulating drive assembly is connected to the track, and several mechanical grippers are connected to the circulating drive assembly. Several rollers are rotatably connected to the bottom end of each mechanical gripper, and the rollers are engaged with the track. Two positioning plates are connected to the worktable, corresponding to the mechanical grippers at the loading and unloading stations, respectively. Positioning rods are connected to the mechanical grippers. A first cylinder drives the positioning plates to move towards the ends of the mechanical grippers to make them more stable.

[0045] Among them, the fourth cylinder 504 and the fifth cylinder 505 are both slide cylinders.

[0046] The specific working principle of this invention is as follows: S1. Loading: The operator places a sheet of blades 6 into the blade box 302. The third cylinder 311 retracts, and under the push of the movable plate 309, the hook head 305 moves upward. The boss 307 at the top of the hook head 305 inserts into the mounting hole 601 of the bottommost blade 6 in the blade box 302. The linear slide module A303 drives the hook head 305 to move to the mechanical gripper end of the loading station, and the blades 6 are discharged from the blade slot 304. At the same time, the first cylinder 206 and the second cylinder 220 of the loading station extend. The first cylinder 206 drives the positioning plate 204 of the loading station to approach the positioning rod 205, so that the positioning rod 205 is engaged in the U-shaped groove 224, while the second cylinder... 220 extends and squeezes the tail end of the upper clamping plate 217 of the mechanical gripper at the loading station. The mechanical gripper opens, and the blade 6 is moved into the groove 218 of the mechanical gripper by the hook head 305. Then, the first cylinder 206 and the second cylinder 220 retract. Under the tension of the spring, the upper clamping plate 217 and the lower clamping plate 216 close and clamp the blade 6. The positioning rod 205 also disengages from the U-shaped groove 224. The third cylinder 311 extends, and under the push of the movable plate 309, the hook head 305 retracts downward. Driven by the linear slide module A303, the hook head 305 returns to the bottom of the blade box 302 to wait for the next cycle, while the blade 6 in the blade box 302 moves downward under the action of gravity.

[0047] S2. Polishing: The geared motor 208 drives the drive sprocket 209 to rotate, and the drive sprocket 209 drives the chain 211 to rotate in a cycle. Since the base plate 221 is connected to the chain 211, the chain 211 will drive the mechanical gripper to rotate in a cycle along the track 202. When the blade 6 on the mechanical gripper passes the polishing wheel 402, since the wool felt polishing wheel 402 is used, the polishing wheel 402 will wrap around the blade part of the blade 6, thereby achieving the effect of polishing the upper and lower surfaces at the same time.

[0048] S3. Unloading: After polishing, the geared motor 208 drives the blade 6 on the mechanical gripper to continue rotating; when it reaches the unloading station, the fourth cylinder 504 drives the tracing rod 503 to move upward so that the tracing rod 503 is inserted into the mounting hole 601 of the blade 6; the first cylinder 206 and the second cylinder 220 of the unloading station extend, the first cylinder 206 drives the positioning plate 204 of the unloading station to approach the positioning rod 205 so that the positioning rod 205 is engaged in the U-shaped groove 224, while the second cylinder 220 extends... The upper clamping plate 217 of the mechanical gripper at the extrusion station is opened; the fifth cylinder 505 drives the cutting rod 503 to move the blade 6 out of the mechanical gripper, and under the action of gravity, the blade 6 falls to the bottom of the cutting rod 503; the first cylinder 206 and the second cylinder 220 retract, and under the action of the spring, the upper clamping plate 217 and the lower clamping plate 216 close, and the positioning rod 205 also disengages from the U-shaped groove 224; the fourth cylinder 504 drives the cutting rod 503 to move downward, waiting for the next cycle. When the blade 6 on the first cutting rod 503 is full, the linear slide module B501 will drive the cutting table 502 to move and use the second cutting rod 503 to receive the material.
