Description

System for systematically and automatically preventing product from being stained and working method

Technical Field

The invention belongs to the technical field of semiconductor packaging, and particularly relates to a systematic automatic product contamination prevention system and a working method.

Background

At present, according to the automatic flow monitoring of a liquid medicine machine, the principle and the functions are as follows:

1. monitoring whether the switch of the liquid medicine machine is manually closed and the liquid medicine pump works normally in real time;

2. the infusion tube is provided with a flow sensor, so that whether the infusion tube has air, blockage, liquid leakage and bending to cause no liquid medicine output phenomenon is monitored in real time;

3. and a three-color lamp and a buzzer are additionally arranged, and sound and light alarm reminding is given out when the abnormity occurs.

The alarm function can not be realized under the condition that the whole power circuit of the liquid medicine machine is powered off (such as the power plug of the liquid medicine machine is loosened, a patch board is tripped, and the like), or the liquid medicine machine alarms, and the contamination abnormity can be caused when people find the liquid medicine machine in time. The scribing liquid medicine machine cuts off the power supply and causes that the batch products are stained abnormally for a plurality of times, the problems that the press welding and the routing can not be performed or the false welding can not be performed and the like are caused, the product quality is seriously influenced, the frequent alarm is given and the reliability verification is required to be performed during the processing, and the processing efficiency of the products is greatly reduced.

Disclosure of Invention

The invention aims to overcome the defects and provide a systematic and automatic product contamination prevention system and a working method, so that the running stability of equipment is ensured, and the processing efficiency of products is improved.

In order to reach above-mentioned purpose, a system is stained to automatic prevention product of systematization, including the relay KA1 that is used for controlling the work of cooling water pump, the relay KA2 that is used for controlling warning circuit and the relay KA3 that is used for detecting liquid medicine machine operating condition, cooling water pump is connected to relay KA1, the one end connection of relay KA2 connects the PLC controller, warning circuit is connected to the other end, the slicer is connected to relay KA 3's one end, the other end is continuous with relay KA2, the PLC controller is used for receiving relay KA 2's information, and transmit to the host computer.

One end of the relay KA3 is connected with a main shaft cooling water Sensor switch of the slicer.

Under the initial condition, relay KA1 and relay KA3 all keep closed, and relay KA2 keeps opening, and when the liquid medicine machine is unusual, relay KA2 is closed, and when the cooling water of slicer is unusual, relay KA3 opens, and relay KA2 is closed.

And a group of normally closed pins of the relay KA2 is connected with a group of normally open pins of the relay KA 3.

A systematic automatic prevention product stains the systematic working method of the system, when the liquid medicine machine is unusual, relay KA2 is closed, trigger the warning circuit;

when the cooling water of the slicing machine is abnormal, the trigger relay KA3 is switched off, so that the relay KA2 is closed to open the alarm circuit.

When the cooling water of the slicing machine is abnormal, the main shaft cooling water Sensor switch of the slicing machine has no signal, and the trigger relay KA3 is switched off.

Compared with the prior art, the relay KA2 and the relay KA3 are linked, so that the abnormity of the water dispenser and the slicing machine can be reported in time, the alarm is triggered, the batch contamination times can be effectively reduced, the product processing quality and the production efficiency are improved, the time for performing reliability verification by manpower is shortened, the labor cost is reduced, and the enterprise profit is improved.

When the liquid medicine machine is abnormal, the relay KA2 is closed to trigger the alarm circuit; when the cooling water of the slicing machine is abnormal, the trigger relay KA3 is switched off, so that the relay KA2 is closed to open the alarm circuit. The linkage of the liquid medicine machine and the dicing saw is realized, the stability of the operation of the equipment is ensured, and the processing efficiency of the product is improved.

FIG. 1 is a block diagram of the system of the present invention.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Referring to fig. 1, a system is stained to automatic prevention product of systematization, including the relay KA1 that is used for controlling the work of cooling water pump, the relay KA2 that is used for controlling warning circuit and the relay KA3 that is used for detecting liquid medicine machine operating condition, cooling water pump is connected to relay KA1, the one end connection of relay KA2 connects the PLC controller, warning circuit is connected to the other end, the slicer is connected to relay KA 3's one end, the other end links and relay KA2, the PLC controller is used for receiving relay KA 2's information, and transmit to the host computer. One end of the relay KA3 is connected with a main shaft cooling water Sensor switch of the slicer.

The relay KA1, the relay KA2 and the relay KA3 are all powered by a 24V power supply, and a group of normally closed pins of the relay KA2 is connected with a group of normally open pins of the relay KA 3.

When the liquid medicine machine is abnormal, the relay KA2 is closed to trigger the alarm circuit; when the cooling water of the slicing machine is abnormal, the main shaft cooling water Sensor switch of the slicing machine has no signal to trigger the relay KA3 to be switched off, so that the relay KA2 is closed to start the alarm circuit.

The invention can reduce the batch contamination times: about 4 times per year; the pressure welding processing time can be saved: about 1152 hours/year and 1 manpower. According to the fact that 6 batches of products are contaminated each time, the time consumed by pressure welding and frequent alarm processing of each batch of products is 48 hours more than usual. The product reliability verification time can be saved: about 864 hours/year and 2 manpower.

Verification of authenticity as per batch takes 36 hours: and (4) extracting 2010, and performing 1-time reflow soldering (230 ℃, nitrogen protection), TCT30, manual OS measurement and FA analysis on defective products.

1 price quote is about 10700 yuan per unit (Meijin) through Disco transformation in the prior art; the third party reforms the quote by about 1000 dollars per station (RMB).

The invention can be used for transforming about 200 yuan/platform (RMB) by self, the design cost is saved by about 800 yuan/platform, which accounts for 80% of the cost, and one 59 scribing machines can save about in total: 4.72 ten thousand yuan (RMB).
