PCB product switching closed-loop control production process

Abstract

The invention discloses a PCB (Printed Circuit Board) product switching closed-loop control production process, which comprises the following steps of: A, transformation: additionally arranging a first control panel and an indicator lamp at the front end of automatic circulation processing equipment, and additionally arranging a second control panel associated with the first control panel at the tail end of the automatic circulation processing equipment; b, pilot production of the first batch of PCB products; c, switching production of the PCB products: after the last part of the first batch of PCB products flows out of the tail end, an operator at the tail end carries out identity authentication and product complete outflow confirmation through a second control panel, an orbital transfer signal is closed, an indicator lamp at the front end emits light with a permitted color, the system operation authority of the automatic circulation processing equipment is started, and the products are allowed to be switched; and D, circulating production. By means of the mode, the PCB product switching closed-loop control production process is beneficial for tail end operators to confirm the outflow of the tail parts of the products, the problem that orbital transfer is carried out under the condition that the last batch of products do not flow out is avoided, and the safety of product switching is improved.

Description

technical field [0001] The invention relates to the technical field of PCB product production, in particular to a PCB product switching closed-loop control production process. Background technique [0002] With the continuous improvement of the production process of PCB products, the degree of automation of its processing has been continuously improved. Except for a few manual steps, automatic production has basically been realized. For example, the reflow soldering of PCB products can use reflow soldering equipment for automatic production. According to different products, the reflow soldering equipment can set the corresponding furnace temperature and change the track to adapt to the soldering of various PCB products. [0003] In the process of reflow soldering production, if the furnace temperature is not adjusted when the product is switched, the corresponding soldering cannot be completed, and even the problem of PCB jamming and track deformation occurs. Whether the PC...

AI Technical Summary

Problems solved by technology

[0003] In the process of reflow soldering production, if the furnace temperature is not adjusted when the product is switched, the corresponding soldering cannot be completed, and even the problem of PCB jamming and track deformation occurs. Whether the PCB is squeezed by the track or the track is deformed, it is Irreversible, the loss is large, and the deformation of the track will make it impossible to continue production, and it is necessary to wait for the replacement of spare parts, which delays the delivery date

In the actual production process, if the front and rear operators do not communicate and confirm the completion status of the work order, and directly clear the reflow status and execute the next work order program, accidents are likely to occur

[0004] Normally, when products are switched, the corresponding furnace temperature parameters will be adjusted and track changed. However, if the PCB products have small batches and many varieties, the switching between products is relatively frequent, and the control of nodes depends entirely on human subjective consciousness. Not only is the efficiency low, but it is also easy to cause the quality of the product itself to be unable to guarantee due to personnel negligence, and even cause serious damage to the production equipment.
