Description

Technical Field

[0001] This utility model relates to the technical field of tin furnace products, and in particular to an electromagnetic pump tin furnace. Background Technology

[0002] In existing technologies, selective wave soldering furnaces employ two methods for driving the solder wave: mechanical pumps and electromagnetic pumps. Solder furnaces using mechanical pumps have the advantages of smaller solder capacity and faster heating, typically reaching operating temperature within 30-45 minutes. Electromagnetic pump furnaces, currently limited by their bottom-mounted heating coils, typically require 60-70 minutes to reach operating temperature. An electromagnetic pump structure, such as the one disclosed in patent number 2013204467269, involves inserting a heating rod into a flow guide tube on the bottom sealing block for heating. The disadvantage of this structure is the tendency to generate solder dust, leading to poor soldering and PCB contamination. Utility Model Content

[0005] In one embodiment, the lower furnace body is cylindrical in shape, and the trough includes two beginning and ending sections that are both connected to the bottom surface of the lower furnace body and a connecting section that connects the two beginning and ending sections. The connecting section is not connected to the bottom surface of the lower furnace body.

[0006] In one embodiment, both of the beginning and ending segments are curved, and the shape formed by the two beginning and ending segments and the connecting segment is a uniform wavy curve.

[0007] In one embodiment, the two beginning and ending segments are in a straight line shape parallel to the length direction of the lower furnace body. The connecting segment includes at least two straight line segments parallel to the beginning and ending segments. A plurality of straight line segments are evenly distributed between the two beginning and ending segments. The beginning and ending segments are connected to adjacent straight line segments and adjacent straight line segments in series through semi-circular segments.

[0008] In one embodiment, the electric heating element is an electric heating tape.

[0009] In one embodiment, the electric heating element is a heating rod.

[0010] In one embodiment, the electric heating element is a heating wire.

[0011] In one embodiment, the upper furnace body is cylindrical in shape, and the outer diameter of the upper furnace body is larger than the outer diameter of the lower furnace body.

[0012] The beneficial effects of this utility model are as follows: a groove is cut in the lower furnace body to embed an electric heating element. The electric heating element can generate heat after being energized, thereby making the tin furnace heat more uniform and faster, greatly shortening the time from start-up to normal operation, and avoiding the problem of tin ash causing defects.
