Abstract

PURPOSE:To enable semiautomatic soldering in accordance with the accuracy by one device by changing the conveying interval of printed circuit boards and the time for dipping the same into a solder tank and pressing the electronic parts on the boards according to the required accuracy. CONSTITUTION:The change lever 6a of a panel control 13 is shifted downward to travel a chain 10 in the direction A if high accuracy of soldering is not required. Printed circuit boards 15 on which electronic parts 16 are mounted are successively placed on all the carriers 5 of the chain 10 and are fed to a flux tank 18, a preheating tank 19 and a solder tank 20, by which the boards are soldered. The soldered boards are taken out in the lowermost position of guide rails 11. If the high accuracy of soldering is required, the lever 6a is shifted upward and every other carriers 5 are removed. The boards 15 on which the electronic parts 16 are mounted are placed on such carriers to extend the dipping time in the tank 20 and the parts 16 are pressed by stopping the boards during the intervening time.

Conventionally, there are two types of printed circuit boards: consumer printed circuit boards used in household tape recorders, televisions, etc., and industrial printed circuit boards used in industrial computers, robots, etc. Printed circuit boards do not require very high soldering accuracy, but industrial printed circuit boards require much higher soldering accuracy and reliability than consumer printed circuit boards. Therefore, when an industrial printed circuit board is placed on the carrier and electronic components are soldered, the electronic component is manually pressed into the container just before the 7 lux coating process, and the lead wires of the electronic component are printed. It is necessary to insert it securely into the board. If the lead wire is inserted incorrectly and the lead wire is floating in the middle, the soldering will be defective and the electronic circuit will fail, such as a break in the ribs. Such failures are caused by industrial printed circuit boards. This is a fatal flaw and must be completely prevented.

However, the time it takes to perform this suppression work is approximately 30 to 60 seconds, depending on the ability of the worker, and if the carrier is stopped for this period of time, the printed circuit board immersed in the solder will be damaged. If the first hour is too long, the lead wires will be deformed due to overheating and the soldering of the lead wires will be defective. Therefore, automatic soldering equipment for consumer printed circuit boards must be used to suppress this work. was impossible. Therefore, in conventional soldering of industrial printed circuit boards, automatic soldering exclusively for industrial printed circuit boards had to depend on equipment, and moreover, automatic soldering equipment exclusively for industrial printed circuit boards had a long operating time. It had the disadvantage of being very uneconomical because it was short and the equipment cost was high.

The present invention has been made to eliminate the drawbacks of the prior art described above, and its purpose is to transport a plurality of carriers intermittently at regular intervals and on which printed circuit boards are placed. In the case of a consumer printed circuit board that does not require precision, high-level soldering is used in its entirety17.In the case of an industrial printed circuit board that requires precision, high-level soldering is used by removing every other board1-. By soldering electronic components to each printed circuit board, there is enough time to press the electronic components mounted on the industrial printed circuit board immediately before the flux application process to ensure their insertion. By switching between automatic soldering machines for consumer printed circuit boards, it is possible to solder industrial printed circuit boards as well. Automatic soldering exclusively for industrial printed circuit boards, which requires short time and high equipment costs, eliminates the need to install equipment and significantly reduces equipment costs. Another objective is to determine the running speed of the carrier when soldering a consumer printed circuit board by using all five carriers, and when soldering an industrial printed circuit board by removing every other carrier. By providing a changeover switch that can change the running time, it is possible to obtain the optimum carrier running speed and running time according to the specifications of the printed circuit board, thereby improving production efficiency. Another purpose is to provide a timer that sets the suppression work time for electronic components mounted on industrial printed circuit boards, so that the suppression work time can be adjusted according to the ability of the worker. The aim is to improve the adaptability of the device to

Since the present invention is configured and operates as described above, a plurality of carriers, which are transported intermittently at regular intervals and on which printed circuit boards are mounted, can be transported with a solder sieving ratio of 1≦t. In the case of consumer printed circuit boards that do not require a high degree of soldering, all boards are used once, and in the case of industrial printed circuit boards where high precision can be achieved, every other board is used. Since half of the parts are attached, there is enough time to press the electronic parts mounted on the industrial printed circuit board immediately before the flux application process to ensure their insertion. Therefore, a single automatic soldering machine for consumer printed circuit boards has the effect of being able to perform semi-electronic soldering of industrial printed circuit boards by switching devices, and as a result, the operating time can be reduced. Automatic soldering for industrial printed circuit boards, which is short and has high equipment costs, does not require the installation of equipment, which has the advantage of significantly reducing equipment costs.

You can also change the carrier running period and time between when soldering a consumer printed circuit board using all the carriers and when soldering an industrial printed circuit board by removing every other carrier. Since the carrier is provided with a changeover switch that allows the carrier to run, it is possible to obtain the optimum running distance and running time of the carrier according to the specifications of the printed circuit board, which has the effect of improving production efficiency. Furthermore, since a timer is provided to set the suppression work time for electronic components mounted on industrial printed circuit boards, it is possible to adjust the suppression work time according to the ability of the worker. This has the effect of improving adaptability.
