Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of feeding equipment, in particular to a puncture device feeding device with position correction function and method. BACKGROUND

[0002] The puncture device is used to establish a channel in the abdominal wall of the human body for laparoscopes or other surgical instruments to enter the abdominal cavity, and to provide a channel for gas to enter and exit to control the required pneumoperitoneum during surgery. In the production process of the puncture device, the workpiece needs to be transferred and processed by the feeding device. In such industrial production, the transmission device is widely used to transfer the workpiece to be processed or the finished workpiece to the next process, which can separate the manual operation from the production line and improve the automation level. The type of transmission device responsible for conveying the workpiece to be processed is also called feeding conveying device.

[0003] The above-mentioned feeding conveying device is generally equipped with a mechanical hand at the rear end for grabbing the puncture needle workpiece thereon to other equipment for continuous processing and handling. However, the mechanical hand grabbing requires a certain distance between the adjacent puncture needle workpieces for grabbing, and the puncture needle workpiece needs to be in the same straight line of conveying. Therefore, the feeding conveying device needs to have the function of repositioning and posture adjusting the puncture needle workpiece. However, the common feeding conveying device does not have such function, and can only transport the workpiece between positions. It cannot ensure that the puncture needle workpiece is in the middle of the conveying structure, and needs to be adjusted manually in the subsequent process. Moreover, the mechanical hand needs to cooperate with the sensor to identify and position the target each time, which is a complicated process and requires high equipment, affecting the overall puncture needle workpiece feeding efficiency.
