Description
Technical Field
[0001] The utility model relates to the technical field of automated needle insertion equipment, in particular to a needle removal device for a needle insertion machine. Background Art
[0002] In the field of automated production technology, the needle insertion operation mainly involves setting a cylinder as a driving part to grab and insert the needle body, but the needle body is generally set on a material belt. At this stage, a feeding and needle insertion separation method is adopted, that is, the feeding device feeds the needle body, and when it reaches the feeding position, the needle body is transported to the needle insertion device through an intermediate conveyor. During the needle removal process, the stability of the PIN needle on the pillow has a crucial influence on the subsequent stability of the needle disk. If the needle head becomes uneven during the grabbing process, the subsequent process will be affected. Since the PIN needle itself is small in size, it is difficult to control the accuracy of the large-stroke clamp during the grabbing process, resulting in unsatisfactory PIN needle grabbing effect. Therefore, a needle removal device for a pin insertion machine is needed. Utility Model Content
