Description

Technical Field

[0001] This utility model relates to the technical field of SMT surface mount production lines, and in particular to a device for a quality control alarm system. Background Technology

[0002] If, during normal production, quality inspectors find three identical defects, three consecutive different defects, or more than five defects in one hour at the remote management station, they need to notify the technician to stop the furnace front track, analyze the cause of the defects, and restart the furnace front track and resume normal production after the technician has made adjustments and improvements to address the quality issues.

[0003] The existing technology has the following drawbacks:

[0004] a. When the quality inspectors at the remote management station discover that a batch of products are defective, they cannot stop the furnace track immediately, causing defective products from the previous process to continue flowing into the next process, resulting in a large number of defective products.

[0005] b. Remote quality inspectors cannot quickly start the track after the anomaly is resolved. Utility Model Content

[0006] The main technical problem solved by this utility model is to provide a device for a quality control alarm system. When the staff finds a batch of defects on the furnace front track, they can immediately stop the furnace front track to prevent the defects from flowing into the next process. Technicians can quickly arrive at the scene to handle the abnormality through the quality control alarm light.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a device for a quality control alarm system, used to control the start and stop of the furnace front track, comprising: a control unit, a remote controller, an intelligent remote control switch receiver installed inside the furnace front track, an intermediate relay, a power supply box, and a quality control alarm light installed on the furnace front track. The input terminal of the intelligent remote control switch receiver is electrically connected to the power supply box, the output terminal of the intermediate relay is electrically connected to the intermediate relay, the input terminal and the output terminal of the intermediate relay are respectively electrically connected to the control unit, and the quality control alarm light is electrically connected to the intermediate relay. The intelligent remote control switch receiver, the intermediate relay, the control unit, and the quality control alarm light are connected in series to form a control loop.

[0008] In one embodiment, the remote controller is connected to a smart remote control switch receiver.

[0009] In one embodiment, two remote controllers are provided, one placed next to the furnace rail and the other placed at the remote management station.

[0010] In one embodiment, the control unit is a PLC (Programmable Logic Controller).

[0011] In one embodiment, the power supply box is a 220V power supply box.

[0012] The beneficial effects of this utility model are as follows: an intelligent remote control switch receiver and an intermediate relay are added inside the furnace front track, and a stop & start remote controller and a quality control alarm light device are added on the track. At the same time, a stop & start remote controller is also added to the remote management station. When the quality inspector at the remote management station finds a defect, he can stop the furnace front track immediately through the remote controller to prevent batch defects from continuing to flow into the next process. At the same time, the quality control alarm light flashes and sounds. After hearing the flashing and sounding of the alarm light, the technicians will arrive at the site as soon as possible to solve the defect problem. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0016] Please see Figure 1The present invention is an embodiment of a quality control alarm system for controlling the start and stop of a furnace track. It includes a control unit 1, a remote controller 2, an intelligent remote control switch receiver 3 installed inside the furnace track, an intermediate relay 4, a power supply box 5, and a quality control alarm light 6 installed on the furnace track. The control unit is a PLC programmable logic controller, the power supply box is a 220V power supply box, the input terminal of the intelligent remote control switch receiver is electrically connected to the power supply box, the output terminal of the intermediate relay is electrically connected to the intermediate relay, the input and output terminals of the intermediate relay are respectively electrically connected to the control unit, and the quality control alarm light is electrically connected to the intermediate relay. The intelligent remote control switch receiver, the intermediate relay, the control unit, and the quality control alarm light are connected in series to form a control loop. By adding an intelligent remote control switch receiver and an intermediate relay inside the track, and using a stop & start remote controller to control the stop and rotation of the track, it is possible to quickly prevent defective products in production from continuing to flow into the next process.

[0017] Using a 220V power supply box and the built-in DC24V power supply and programmable control of a PLC programmable logic controller, an intelligent remote control switch receiver and an intermediate relay are installed inside the furnace front track.
