Description

Technical Field

[0001] The utility model relates to the technical field of SMT production, in particular to a measuring mechanism of a material receiving machine. Background Art

[0002] In the SMT (surface mount technology) industry, electronic components are generally stored in sealed tapes, which are then wound into trays for transportation and storage. Before use, the electronic components in the tape need to be inspected, and the inspection is generally completed by an automatic measuring machine set on the side of the tape conveyor track. When the automatic measuring machine inspects the electronic components, it needs to descend and pierce the packaging film on the tape, and then reach the measuring point on the electronic component to measure the resistance, capacitance or inductance of the product.

[0003] The Chinese utility model patent document with application number CN201922149805.3 discloses an automatic measuring mechanism of an SMT material receiving machine, including a first motor, a second motor, a third motor, a fourth motor, an insulating right needle seat, an insulating left needle seat and a top seat. The insulating left needle seat and the insulating right needle seat are provided with a detection needle. The rotation of the first motor and the second motor drives the sliding of the insulating needle seat to adjust the distance between the two detection needles. The rotation of the fourth motor drives the top seat to move upward to the bottom of the SMT product to fix the measured component. The rotation of the third motor drives the insulating needle seat to move downward to the top of the SMT product to measure the resistance value, capacitance value or inductance value of the product. However, the detection needle and the insulating needle seat of the above-mentioned automatic measuring mechanism are arranged in one body. When the detection needle is damaged, the entire insulating needle seat, including the wiring part, needs to be replaced, which is inconvenient for maintenance operations and has high maintenance costs. In addition, the height difference between the two detection needles in the vertical direction cannot be adjusted. For components with large height differences, if the height difference between the two detection needles is fixed, it may cause inaccurate detection or even damage the components or the detection needle itself.
