Abstract

A device used for coating lead to electrical or electronic components that are placed on supports in line. The bed consists of a lead reservoir with a pair of guides (1,2) for piloting the support to move through the lead reservoir and a device to move the support along the guideline. The guide consists of the first control line area (12,19) to Bringing the lead of the secondary device to the surface of the lead and the gallop area Control the second area (16,20) longitudinally distant from the first area and opposite it. crosswise in order to bring the back of the support device into lead surface at the same time. Both control lines have look alike so that the supporting device will maintain the condition Stay horizontal while being moved in line Plummet to and from the lead surface with the support moving. It is on the driving pulley that moves on the guideline.

Claims (6)

1. In a horizontally arranged carriage assembly (24) consisting of a rail with a number of electronic integrated circuits. Put it inside in such a way that it can lead out with its leading part down. Bottom with a device for welding to the leading portion of the circuit board. The assembly consists of a welding bath (22), a guide rail (1,2) for piloting the carriage through a welding bath, a device (31, 32, 33, 34) driving the carriage along the rail, the first set ( 27) for supporting the carriage guides on the pilot rails, and the second set (29) that is set along the length of the first set. For supporting the rear of the carriage onto the pilot rails, it is unique in that the pilot rails consist of the first edge portion (12,35) used to guide the first set (27) down to the surface (23 ) Of the welding bath And there is a line of the second (16,20) longitudinal from the first edge for introducing the second set (29) down to the surface (23) of the welding bath. At the same time by the area being the first edge And the second (12,35; 16,20) of the rails are apart. And each other horizontally And in which the first and second following sets (27,29) for supporting the guide and rear of the carriage are far apart. And each other across as well So that when the carriage is wrinkled along the first set of pilot rails (27), it passes through the sectional area. The second edge (16,20) goes, and the second set (29) goes through the first edge (12,35), making the area where The two parts are aligned and are located at a distance. Length between each other at the same level as the distance between the series according to the first set and The second set is when the carriage (24) is driven along the guide rail. The grooves are often kept horizontally while the That has been moved vertically towards And exit from the surface of the welding bath to immerse the lead part of the circuit board into the welding bath 2. Carriages and equipment according to claim 1, where pilot rails (1,2) are arranged on each side of the welding bath (22). 3. Carriage and equipment according to claim 1 or 2, where each border area (12, 35; 16,20) consists of an area A down-diagonal (13,17), a diagonal (14,18), and an upward-oblique area (15,19). 4.The carriage and equipment according to claim 1, 2 or 3, in which the device (31, 32, 33, 34) drives the carriage (24) along the guide rail (1,2), consisting of a chain (31, 32). , 33) that is made up of a large number of (34) finger protrusions for attaching the carriage. 5. Carriage and equipment according to one of the above claims In which the vertical area of each section (12, 35; 16,20) can be replaced 6. Any carriage and equipment in accordance with Clause 1 to 4, in which the pilot rail (1,2) consists of a notched section (3,4), which provides a section (7,8) in such The section detachable consists of the first and second boundary (12,35; 16,20) of the pilot rails (6 claims, 2 faces, 2 photos).
