At present, in the field of chip packaging technology, most of the resin is conveyed to a technology-assigned station manually, the production efficiency is low, and the manual operation can contact the resin, which is not beneficial to the improvement of product quality.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the resin detection device of full-automatic semiconductor package equipment and can not detect the damaged resin in side, easily lead to encapsulating the condemned problem of product.
For solving the technical scheme, the utility model discloses a technical scheme is: a resin weighing and detecting device of automatic packaging equipment is characterized by comprising a feeding device, a detecting device and a discharging device, wherein the feeding device comprises a guide cylinder, a material receiving block, a feeding guide rail and a feeding motor, the material receiving block is provided with an accommodating cavity, the accommodating cavity is positioned below the guide cylinder, the material receiving block is connected to the feeding guide rail through a bottom slideway, and the feeding motor is in transmission connection with the material receiving block and drives the material receiving block to move back and forth along the guide rail; the detection device is a weighing detection device, the device comprises a weighing instrument and a weighing block, the weighing block is fixed below the feeding device, the resin is sent to the weighing block by the feeding device for weighing, and the weight of the resin is obtained by the weighing instrument; the discharging device comprises a material receiving block II, a discharging pushing shaft driving device and a discharging track, the material receiving block II is provided with a barrel-shaped containing cavity and is located at the terminal of the feeding guide rail, the discharging pushing shaft is located below the containing cavity of the material receiving block II, and the discharging pushing shaft driving device is in driving connection with the discharging pushing shaft and drives the discharging pushing shaft to move up and down.
By adopting the technical scheme, the materials are fed into the guide barrel through the feeder and then are fed onto the weighing device through the receiving block along the feeding guide rail. The resin is sent into the weighing weight by pan feeding mechanism, weighs to the resin, and the analog signal access encapsulation that the weighing result produced by the weighing instrument gives PLC with data transmission in the AD module, and the operation through PLC sends resin weight into next step's process by discharge device in the deviation scope of setting value, and resin weight is not directly abandoned at the setting value deviation scope to reach the purpose of weighing detection. When the resin transferred from the weighing block is judged to be a qualified product, the discharging push shaft driven by the discharging push shaft driving device moves upwards to jack the resin to the discharging track, and when the resin transferred from the weighing assembly is judged to be an unqualified product, the discharging push shaft driven by the discharging push shaft driving device moves downwards until the resin is separated from the receiving block II, so that the aim of weighing and detecting the resin is fulfilled.
Preferably, the discharging pushing shaft driving device is a discharging air cylinder.
And a waste material box is fixed on one side of the second material receiving block and used for collecting waste resin.
To sum up, the beneficial effects of the utility model are that: the utility model discloses the resin is delivered to the guide cylinder of pan feeding device by the feeder, weighs the detection through the detection device that weighs, again by discharge device discharge resin, the qualified resin of weight uses, and the weight is unqualified will be abandoned the resin, solves the defective problem in side and the great problem of error range that the resin length detection can't be solved, makes the resin qualification rate of sending into encapsulation equipment improve greatly, has also improved the qualification rate of encapsulation product greatly.
