Description
Technical Field
The utility model relates to the field of intelligent production of semiconductor chips, in particular to an SMEMA control box for conveying products among machines.
Background
At the chip rinse station of the semiconductor chip packaging plant, the product is rinsed by a rinse machine (stoning) and then fed into a first-in first-out buffer machine (First In First Out, FIFO). The rinse machine is used to clean the chip to remove excess chemicals that attach to the chip. After the product enters the washing machine through the conveying belt, the product is washed and cleaned through a pressurized water washing area, and then is sent into a high-temperature drying area to dry the residual moisture on the chip. The interface standard, represented by the SMEMA (Surface Mount Equipment Manufacturers Association) protocol, provides a board protocol for typical inter-machine transport products, the core of which specifies that there are at least one pair of handshaking signals between the machines in the preceding and following processes. For example, the flushing machine sends a plate transfer signal to the first-in first-out buffer machine, and the first-out buffer machine returns a feedback signal capable of transferring a plate to the flushing machine after receiving the plate transfer signal, so that the product transfer is finally completed.
If the first-in first-out buffer machine fails, the SMEMA module will not send a feedback signal to the flushing machine, so that the flushing machine is always in a state of waiting for a plate to be discharged, and the product stays in a high-temperature drying area in the flushing machine. If the product stays in the flushing machine beyond the limit value, it will be scrapped due to quality defects. In addition, when the waiting time of the product in the flushing machine exceeds a limit value, the flushing machine is usually set to trigger a global alarm, the water and electricity supply in the machine is closed, the whole machine is forced to stop, and the later production recovery consumes a great deal of time, so that the production efficiency of the product is reduced.
In order to reduce the probability of product scrapping as far as possible, the products are usually taken out one by one from the plate outlet area of the flushing machine by manual operation, but due to the fact that the mesh belt structure is arranged on the conveying belt, if the mesh belt is just positioned in the plate outlet area, the products cannot be taken out smoothly, the product scrapping rate still cannot be reduced, and potential safety hazards such as scalding and clamping exist in manual taking out.
