Description

Technical Field

[0001] The utility model relates to the technical field of particle discharging, in particular to a lead frame pushing mechanism. Background Art

[0002] ASPM27 Unloader (a model of intelligent power module ASPM) is a device used to unload or remove granular or granular materials. It is usually used in automated production lines or industrial production, which can help improve production efficiency and reduce labor costs. The lead frame pusher mechanism is an important component in the ASPM27 Unloader device. Its function is to guide the granular materials so that they can smoothly enter the Unloader (a component of the SMT whole line equipment, specifically, it is the unloader) device from the upper loading port to achieve smooth material import and unloading operations. The lead frame pusher mechanism is usually designed into a specific shape or structure to ensure that the materials can be guided into the Unloader device according to a certain path and speed for subsequent operations and processing. The design and function of the lead frame pusher mechanism directly affect the working efficiency and unloading accuracy of the ASPM27 Unloader device, which can effectively improve the unloading efficiency and reduce possible erroneous operations, ensuring the smooth progress of the entire production process. In general, the lead frame pusher mechanism plays an important role in guiding and importing granular materials in the ASPM27 Unloader device, and is a key component for the normal operation and efficient operation of the device.

[0003] The existing lead frame pushing mechanism discharges materials through the frequent forward and reverse rotation of the rotating motor. The frequent forward and reverse rotation consumes a lot of energy, increasing energy costs. Frequent forward and reverse rotation will cause wear of mechanical parts, shorten the service life of the equipment, and increase maintenance costs. Frequent forward and reverse rotation will produce loud noise, which may affect the working environment and the health of the operator. Forward and reverse rotation may cause unstable discharge, affect production efficiency and product quality, and cause the rotating motor to be subjected to greater impact and vibration.

[0005] In order to achieve the purpose of the lead frame pushing mechanism making the rotating motor continuously rotate forward and push materials quickly, the utility model provides the following technical solutions: the lead frame pushing mechanism comprises a lead frame pushing device and a rotating motor installed inside the lead frame pushing device, a rotating shaft is installed on the outer surface of the output end of the rotating motor, a connecting rod is installed on the outer surface of the rotating shaft, a cam follower is installed on the outer surface of the connecting rod, two slide rails are installed on the outer surface of the lead frame pushing device, a moving block is movably installed on the outer surfaces of the two slide rails, an overload protection block is installed on one end surface of the moving block, two push rods are installed on the outer surface of the overload protection block, an anti-collision block is installed on the outer surface of the lead frame pushing device, and a cam groove is provided on the bottom end surface of the moving block.

[0011] Compared with the prior art, the utility model provides a lead frame pushing mechanism, which has the following beneficial effects:

[0012] The lead frame pushing mechanism increases the pushing speed by making two push rods perform back-and-forth extending and retracting movements through the cooperation of a rotating motor, a rotating shaft, a cam follower and a cam groove, thereby solving the problem that when the rotating motor frequently rotates forward and reverse to discharge materials, the inertia of the rotating motor will change rapidly, causing the rotating motor to be subjected to greater impact and vibration, resulting in increased wear of the rotating motor and a short service life of the rotating motor.
