Description

Technical Field

[0001] The utility model relates to the technical field of preformed soldering sheet production, and more specifically, to a preformed soldering sheet burr processing device. Background Art

[0002] As an essential soldering product in the integrated circuit industry, preforms are increasingly used. During production, they are often made by punching, so they need to be deburred. Burrs are primarily concentrated at the edges of the preforms.

[0003] However, there is currently a lack of good deburring equipment, and manual grinding is still required to a large extent, which is time-consuming and labor-intensive.

[0004] After searching, the Chinese patent with authorization announcement number CN112123194A discloses a burr processing device for preformed welding sheets. The structure pre-installs the welding sheets through a designed adjustable clamping sleeve, and then uses a cylinder cover driven by a first cylinder to compress the stacked welding sheets. Multiple welding sheets can be clamped at one time, which has higher processing efficiency. The welding sheets are supported by a designed turntable, and the turntable is driven by an electric motor to enable the welding sheets to rotate. By filling sand in the corrugated sleeve, when deburring, the push plate is driven upward by the second cylinder to push the sand in the corrugated sleeve into the sand barrel, so that the sand can be brought into contact with the welding sheet. When the welding sheet rotates, it rubs against the sand, and can be quickly deburred. No manual grinding is required, the labor intensity is low, and the work efficiency is high.

[0005] However, when this structure is actually used, the second cylinder is used to drive the push plate to move upward, so that the sand in the corrugated sleeve enters the sand barrel from bottom to top through the through holes on the partition plate, thereby failing to ensure that the sand completely enters the sand barrel, resulting in a small contact area with the welding piece and low friction, which in turn affects the deburring effect.

After one side of the welding piece is polished, start the first electric telescopic rod 8 to move backward to separate the grinding wheel 12 from the welding piece;

[0032] Then start the second stepper motor 19 inside the motor box to drive the rotating rod 20 to rotate, wherein the surface of the motor box is provided with heat dissipation holes, so as not to affect the normal use and heat dissipation of the second stepper motor 19, so that the rotating rod 20 moves with the workbench 21, and the workbench 21 drives the slider 22 at the bottom to slide in the slide groove opened on the surface of the fixed frame 1, thereby playing a limiting role and ensuring stability during the movement, thereby driving the welding piece on the top of the workbench 21 to rotate, so that the lower pressure plate 15 rotates, and the lower pressure plate 15 drives the second electric telescopic rod 14 to rotate inside the U-shaped fixed frame 2 through the bearing 13, thereby rotating to the other side facing the grinding wheel 12, and then grinding is performed according to the above steps, thereby removing burrs around the welding piece.
