Description

Technical Field

[0001] The utility model relates to the field of automation, in particular to a scalpel assembling machine. Background Technique

[0002] A scalpel refers to a special tool composed of a blade and a handle for cutting human or animal tissues, and is an indispensable important surgical tool in surgical operations. Existing scalpels are mainly divided into two categories. One is a scalpel with a fully metal handle and a recyclable tool, and the other is a scalpel with a plastic handle that is inseparable from the blade. The second type of scalpel usually consists of a blade, a blade holder, and a scabbard. The mainstream production method of this type of scalpel in China still relies on manual crimping of the blade and the blade holder, and then assembling with the scabbard. This assembling method has always been inefficient. Moreover, doctors report that the feel is unstable, which is likely to affect the surgical quality. And due to the extremely sharp blade, it is very easy to scratch workers. There are also problems of multiple reworks due to manual installation errors. Therefore, many enterprises have started to explore equipment for automatically assembling scalpels. Content of the Utility Model

Among them, the tool holder loading component realizes the vibrating loading of the tool holder, and the handling robot gripper 10 installed on the upper-layer turntable transports the tool holder into the carrier. The carrier equipped with the tool holder is controlled by a motor to rotate to the blade loading component for blade loading, and then rotates to the riveting component for press riveting, so that the blade and the tool holder are integrated. Before the press riveting is detected by the first vision inspection component, the qualified ones are sent into the second turntable through the transfer component, while the unqualified ones are discharged through the defective product discharging component.

[0024] The second turntable is a single-layer structure and is driven to rotate by a motor on the back. A plurality of second carriers 31 are equidistantly arranged on the surface of the second turntable. At the same time, a knife sheath loading component 11, a pushing-in component 12, a second vision inspection component 13, a second defective product discharging component 14, and a finished product discharging component 15 are respectively arranged at different workstations around the second turntable. Among them, the knife sheath loading component cooperates with the knife sheath handling robot gripper 16 installed on the cabinet to send the knife sheath into the second carrier, and rotates to the transfer component to load the crimped scalpel.

The unqualified products are discharged through the second defective product discharging component, and the qualified products are discharged through the finished product discharging component.

[0025] Specifically, the tool holder loading component includes a first vibrating disk 51 and a tool holder loading track 52. The tool holders in the first vibrating disk are sequentially transported into the tool holder loading track and conveyed forward under vibration, and then the tool holder is loaded by the handling robot gripper. The structure of the handling robot gripper is as Figure 4 shown, including a lifting cylinder 101, a telescopic cylinder 102 fixed on the lifting block of the lifting cylinder, and a pneumatic claw 103 fixed on the telescopic end of the telescopic cylinder. The telescopic cylinder controls the pneumatic claw to extend to the tool holder loading track to clamp the tool holder and retract to the carrier, and the lifting cylinder controls the lifting to make the tool holder fall into the carrier.

The surface of the blade conveying track is provided with a slide rail 67, and a sliding stopper 68 is arranged on the slide rail. The blades are vertically placed on the blade conveying track and are blocked from the outside by the stopper to prevent the vertically placed blades from tipping over. The sliding pusher has a pushing cylinder and a push block located at the telescopic end of the pushing cylinder. The side of the push block is attached to the side wall of the blade at the feeding end of the blade conveying track, and the blade is pushed out from the side notch by the pushing cylinder and enters and is attracted to the side wall of the first electromagnet flush with the feeding end surface of the blade conveying track.

The blade on the second electromagnet is sucked by the electromagnetic chuck, and the blade is fed into the carrier and combined with the tool holder in cooperation with the linear module and the lifting cylinder.

[0028] There are two sets of riveting assemblies, which respectively realize the press riveting of the front end and the rear end of the blade and the tool holder. The structures of the two sets are the same. Specifically, as Figure 6 shown, it includes a column 71, a press riveting cylinder 72 fixed on the column, and a pressing block 73 arranged at the telescopic end of the press riveting cylinder. The press riveting of the blade and the tool holder is realized by controlling the pressing block to move downwards by the press riveting cylinder.
