Abstract
The invention relates to an alarming method for touching a metal bonding wire in a chip by a dispensing head of an LED dispensing machine, which relates to the technical field of LED dispensing. The metal welding wire can be touched by the point gum head to give an alarm in time, so that the risk is reduced, the product is isolated, and the possibility of outflow control due to the fatal quality defect of the product is avoided.
Description
Technical Field
The invention relates to the technical field of LED dispensing, in particular to an alarming method for touching a metal bonding wire in a chip by a dispensing head of an LED dispenser.
Background
With the rapid development of the lighting industry in recent years, the number of various models of LED dispenser is infinite, and the UPH of the dispenser is also increasing, but the increasing UPH means the quality risk is also increasing in proportion. For example, the dispensing head may cause a fatal problem of wire bonding in the chip during dispensing, and the machine may not detect the risk of product outflow control.
The glue dispensing head of the current glue dispensing machine table is only controlled by software, and hard limit is not provided. I.e., there is a risk that the dispensing head touches the die bond wires without feedback from the machine. This risk is fatal to the reliability of the product, and a method capable of timely alarming when the dispensing head touches the metal welding wire is needed.
Disclosure of Invention
The invention aims to provide a reasonably designed alarming method for touching the metal bonding wires in the chip by the dispensing head of the LED dispenser, aiming at the defects and shortcomings of the prior art, and the alarming method can be used for timely alarming when the dispensing head touches the metal bonding wires, reducing risks, isolating products and avoiding the possibility of outflow control due to fatal quality defects of the products.
In order to achieve the purpose, the invention adopts the following technical scheme: the operation steps are as follows: connect PLC between foot rest arm and machine metal bottom plate to connect the alarm on this PLC, then when getting into machine metal bottom plate with metal support, the cylinder jacking is tight with the machine metal bottom plate clamp and is laminated and switch on metal support, when the dispensing head descends the point glue or staff debug dispensing head position at high-speed operation, in case the dispensing head touches chip metal bonding wire in the chip, then the dispensing head links up with the metal bottom plate, and form a return circuit with PLC, PLC reads this return circuit signal, thereby control machine reports to the police immediately and shuts down.
Further, the PLC model is KEYENCE KV-N6 OAT.
Furthermore, the metal bottom plate of the machine is electrically connected with the public end of the PLC, and meanwhile, the glue dispensing arm is electrically connected with the input end of the PLC.
Furthermore, the alarm is connected with the output end of the PLC.
Furthermore, the connecting line of the PLC and the metal bottom plate of the machine is grounded.
After adopting the structure, the invention has the beneficial effects that: the invention provides an alarming method for touching a metal bonding wire in a chip by a dispensing head of an LED dispenser, which can alarm in time when the dispensing head touches the metal bonding wire, reduce risks, isolate products and avoid the possibility of outflow control due to fatal quality defects of the products.
