Description

Technical Field

[0001] The utility model relates to the technical field of sorting machines, in particular to a high-speed sorting machine for chip resistors. Background Art

[0002] Chip resistors, also known as chip fixed resistors, are sheet-shaped resistor devices that can be easily connected to a variety of devices such as circuit boards, so they are widely used. Existing chip resistors need to be tested for resistance before being packaged in carrier tape after the process is completed.

[0003] In the process of automatic sorting of existing chip resistors, the products are first sorted into the same arrangement by a circular vibration plate, and then pushed to the sorting position by direct vibration. Since the products are pushed by direct vibration, the products cannot return to the position of the suction nozzle in time, resulting in a long idle time, which seriously reduces the efficiency of sorting. At the same time, the traditional chip resistor sorting fixture has a complex structure, troublesome operation, and easy to fall off, which seriously affects the efficiency and accuracy of resistor sorting. A Chinese patent discloses a "high-speed sorting machine for chip resistors", which is applied for "C N202122183805.2", which uses a testing mechanism to detect the resistance of the resistor grabbed by the vacuum suction cup, and the turntable conveying mechanism drives the chip resistor on the vacuum suction cup to be unloaded into the corresponding receiving cavity of the receiving mechanism, so that the product of chip resistors with different precisions can be tested, which improves the accuracy of chip resistor sorting and the grading is accurate. The addition of the turntable conveying mechanism makes the sorting faster and can create more economic benefits for the enterprise. However, it does not take into account the problem of insufficient accuracy of the fixture of the existing equipment during the clamping process, and does not take into account the problem of low efficiency of sorting. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a high-speed sorting machine for chip resistors.

The clamping plate clamps the chip resistor under the push of the spring, making the clamping process more stable and accurate. This coordinated design can ensure the stability of the position of the chip resistor during the clamping process, which is conducive to the subsequent clamping, detection and sorting operations, and improves the accuracy and reliability of the equipment. At the same time, the chip resistors are sorted by the electric telescopic rod 1 in cooperation with the connecting pipe, and the chip resistors are quickly and accurately sorted into qualified or unqualified material distribution trays, which improves the sorting efficiency.
