Lead frame transmission device

Abstract

The invention discloses a lead frame transmission device which comprises a steel channel (1), motors (2) and a transmission mechanism, wherein the transmission mechanism comprises pinch wheels I (3), pinch wheels II (4), belt wheels I (5) and belt wheels II (6); the pinch wheels I (3), the belt wheels I (5) and the belt wheels II (6) are rotationally mounted on an internal wall of the steel channel (1) along rotating shafts from one end of the steel channel (1) to the other end of the steel channel (1); the pinch wheels II (4) are arranged above the pinch wheels I (3) and pressed on belts I (7); the transmission mechanism is symmetrically arranged on the internal wall on the two sides of the steel channel (1); the rotating shafts of the two belt wheels II (6) are connected with the motors (2) respectively; and the two motors (2) are arranged outside the steel channel (1).The device has the benefits that the device is simple in structure, can effectively avoid belt slip and prevent tablets from being stuck in a material box, improves the production efficiency and reduces therejection rate of products.

Description

technical field [0001] The invention relates to the technical field of conveying materials used in the electronics industry, in particular to a lead frame transmission device. Background technique [0002] At present, most of the electronic products produced in the electronics industry need to use blanks, which are rectangular in shape, made of metal, and the surface of the blanks is smooth and flat. The blanks are generally stacked layer by layer in the material box. When the blanks are to be transported to the processing equipment, it is necessary to use the lead frame transmission device to transport the blanks to the processing equipment to complete the cutting process. Existing lead frame transmission device is made up of machine base and two pulleys, and two belt pulley rotating shafts are installed on the machine base in rotation, and belt is installed between two belt pulleys, and when using, start motor, and motor drives belt pulley to rotate, and when material piec...

Problems solved by technology

Existing lead frame transmission device is made up of machine base and two pulleys, and two belt pulley rotating shafts are installed on the machine base in rotation, and belt is installed between two belt pulleys, and when using, start motor, and motor drives belt pulley to rotate, and when material piece When being pushed out one by one from the magazine, the blanks fall on the belt, so the blanks are transported to the processing equipment along with the belt, however, some blanks are slightly deformed or have burrs, so the blanks will Stuck in the material box, unable to fall on the belt, the phenomenon of material jam occurs, which seriously affects the production efficiency. In addition, due to the long-term use and wear of the belt, the belt is easy to slip, and the materials on the belt will rub against each other after the belt slips , the sheet is scratched, which undoubtedly reduces the scrap rate of the product
