Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, and in particular to a circulating conveying mechanism of 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 cutting blades, the cutting edge needs to be ground, and the ground edge will have burrs, so polishing is required. The circulating conveyor mechanism is the mechanism on the polishing device responsible for circulating and conveying the cutting blades. The existing circulating conveyor mechanism does not have a positioning device, which means that during loading, the mechanical gripper cannot accurately pick up the cutting blade from the loading mechanism, and during unloading, the mechanical gripper cannot accurately place the cutting blade on the unloading mechanism, thus affecting work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a circulating conveying mechanism for a surgical blade circulating polishing device, which is equipped with a positioning rod and a positioning plate. During loading and unloading, the positioning rod is engaged in the positioning plate to determine the position of the mechanical gripper, making loading and unloading more accurate and ensuring work efficiency, thereby solving the problems mentioned in the background art.

Two positioning plates 204 are connected to the worktable 201, and the two positioning plates 204 correspond to the mechanical grippers at the loading and unloading stations, respectively. Positioning rods 205 are connected to the mechanical grippers. A first cylinder 206 drives the positioning plates 204 to move towards the mechanical gripper end so that the positioning rods 205 are engaged in the positioning plates 204.

[0023] The bottom of the workbench 201 is connected to several uprights 207, and the bottom of the uprights 207 is connected to the machine base 1; the track 202 is a closed ellipse, and the inner and outer sides of the track 202 are provided with slots.

[0024] The cyclic drive assembly includes a geared motor 208, a drive sprocket 209, a driven sprocket 210, and a chain 211. The geared motor 208 is connected to the bottom of the workbench 201 via a motor mount. The drive sprocket 209 is connected to the power output end of the geared motor 208. The other end of the workbench 201 is connected to a bearing 212. A rotating shaft 213 is rotatably connected to the bearing 212. The driven sprocket 210 is connected to the top of the rotating shaft 213. The chain 211 is connected between the drive sprocket 209 and the driven sprocket 210.

[0025] The mechanical grippers consist of six sets, each including a base plate 214, a base 215 connected to the base plate 214, a lower clamping plate 216 connected to the base plate 214, and an upper clamping plate 217 connected to the base 215. A spring connects the upper clamping plate 217 and the lower clamping plate 216 to keep the mechanical grippers in a normally closed state. A groove 218 for accommodating the blade 6 is provided between the upper clamping plate 217 and the lower clamping plate 216. A top plate 219 is connected to the worktable 201, and two vertically arranged second cylinders 220 are connected to the top plate 219. The two second cylinders 220 correspond to the mechanical grippers at the loading and unloading stations, respectively. When the second cylinders 220 extend, they press down on the tail end of the upper clamping plate 217 at the loading and unloading stations to open the mechanical grippers.

[0026] The base plate 214 is connected to the bottom of the base plate 221, and the rollers 203 are rotatably connected to the base plate 221. There are two sets of rollers 203, which are in pairs. The two sets of rollers 203 are respectively engaged in the slots inside and outside the track 202, and the base plate 221 is connected to the chain 211.

[0027] The workbench 201 below the top plate 219 is connected to a support plate 222. Two first cylinders 206 are respectively connected to the support plate 222, and two sets of slide rail assemblies 223 are connected to the support plate 222. Two positioning plates 204 are respectively connected to the slide blocks of the slide rail assemblies 223, and the two positioning plates 204 are respectively connected to the power output ends of the two first cylinders 206. The positioning plates 204 are provided with U-shaped grooves 224. The positioning rod 205 is connected to the bottom plate 221. When the first cylinder 206 extends, it drives the positioning plate 204 to approach the positioning rod 205 so that the positioning rod 205 is engaged in the U-shaped groove 224.

[0028] The specific working principle of this utility model is as follows:

[0029] This utility model is used in conjunction with a feeding mechanism, a polishing mechanism, and a discharging mechanism.

[0030] When the blade 6 is being fed, the first cylinder 206 drives the positioning plate 204 of the feeding station to approach the positioning rod 205, so that the positioning rod 205 is engaged in the U-shaped groove 224. Meanwhile, the second cylinder 220 extends and presses the tail end of the upper clamping plate 217 of the mechanical gripper of the feeding station. The mechanical gripper opens, and after the blade 6 is moved by the feeding mechanism into the groove 218 of the mechanical gripper, 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, and the positioning rod 205 also disengages from the U-shaped groove 224.

[0031] The geared motor 208 drives the drive sprocket 209 to rotate, and the drive sprocket 209 drives the chain 211 to rotate cyclically. Since the base plate 221 is connected to the chain 211, the chain 211 will drive the mechanical gripper to rotate cyclically along the track 202. The blade 6 on the mechanical gripper is polished by the polishing mechanism.

[0032] After polishing, the geared motor 208 drives the blade 6 on the mechanical gripper to continue rotating; when it reaches the unloading station, the unloading mechanism docks with 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 and squeezes the tail end of the upper clamping plate 217 of the mechanical gripper of the unloading station, and the mechanical gripper opens; under the action of gravity, the blade 6 falls onto the unloading mechanism.

[0033] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
