Monitoring system for the production of printed circuit boards

The present invention relates to a monitoring system for monitoring the processing or production of printed circuit boards in a processing line consisting of several processing stations. *

The processing stations are used, for example, for the production, processing, positioning, assembly, etc. of the circuit boards. Several circuit boards are each arranged in a circuit board magazine. Such a magazine is made of plastic, for example, and comprises a number of vertical slots, each of which holds a circuit board. The magazines with the circuit boards are transported along the processing line from processing station to processing station, with each processing station processing the circuit boards according to the function assigned to it.

The present invention provides a system for monitoring the processing or production of printed circuit boards in a processing line consisting of several processing stations, wherein several printed circuit boards are arranged in a printed circuit board magazine, at least two monitoring devices are provided for monitoring the processing or production of the printed circuit boards, and a central evaluation device is provided which is connected to the at least two monitoring devices via a bus system and which receives status messages from the monitoring devices, evaluates them and transmits them to a remote receiving device.

Fig. 1 shows a schematic diagram of a monitoring system according to the invention, Fig. 2 to Fig. 5 show various selection masks on the screen of the evaluation device, and

Fig. 6 shows a table with error messages on the display of the evaluation device.

Figure 1 shows a schematic representation of a monitoring system according to the invention, wherein a processing line 1 consisting of several processing stations with several monitoring devices is shown. The monitoring

devices are connected to a central evaluation device 3 (computer) via a bus system 2 (CAN bus). The central evaluation device 3 receives the status messages or error messages from the monitoring devices, evaluates them and transmits them to a remote receiving device 4, in the case shown a mobile radio terminal, whereby the responsible person is informed about the status of the system. ,·

The monitoring system according to the invention thus enables simple and unS*i***

• effective status and error monitoring even at remote locations. The evaluation unit 3 can transmit the status messages, for example, as an SMS message*"" or as a telephone call. Furthermore, the evaluation device 3 can send status messages or error messages to the remote receiving device*»»

for example, as an email, in which case the remote form

Receiving device can be a computer. Advantageously, dte; _ei / evaluation device 3 transmits the status messages on the basis of selectable priorities. It is also advantageous if the evaluation device logs the status messages.

The monitoring devices can each be integrated into a processing station and linked to a function for setting the desired parameters. This means, for example, that settings for a processing line can be configured and saved for a specific order using a corresponding selection mask on the screen of the evaluation unit. To process or manufacture semiconductor plates, the desired order is selected, the order size (number of pieces) is specified, and the order is loaded onto the processing stations of processing line 1. When production or processing of the circuit boards begins, the order is started manually or automatically at the first processing station of processing line 1. Within the processing line, each time a magazine with circuit boards is transferred between two processing stations, the order number is passed on and compared with the current order. The order number contains the system parameters and the transport width. If the order number changes, the new parameters are set. This switches processing line 1 serially to the new order.

The monitoring system according to the invention thus also enables order-related line configuration, configuration of the individual processing stations, error logging, parameter query, status and error monitoring, and transmission of the corresponding messages to an operator according to selectable priority by means of SMS message, telephone call,

e-mail or the like. Priorities can be assigned to each status message or error message at the central evaluation device 3, with the message being forwarded to a previously defined location according to this priority.

The evaluation device enables different configuration levels for

inventive monitoring system, namely e.g. the configuration levels*!!

“Download”, “Lines”, “Jobs” and “Module”. *»&iacgr;*»*

Fig. 2 shows an example of a selection mask for the jobs, i.e. for the configuration level "Jobs". Fig. 3 shows an example of a selection mask for the configuration of the processing line, i.e. the configuration level "Lines". Fig. 4 shows an example of a selection mask for orders, i.e. the configuration level "Download". Fig. 5 shows a selection mask for system parameters, i.e. the configuration level "Module". Fig. 6 shows an example of a definition table "Error messages". All representations shown in Figs. 2-6 relate to the display of the evaluation device 3.

The processing stations can be defined using the selection mask for configuring processing line 1. The line sequence, line names and types can be determined here. Furthermore, the system parameters such as the first processing station, the transport width, etc. can be defined using a corresponding selection mask, as well as the number of circuit boards to be manufactured, the line assignment and the order name.
