A chip diode cutting tool

Abstract

The invention relates to a material cutting tool for an SMD diode. The material cutting tool for the SMD diode is characterized in that the material cutting tool for the SMD diode comprises a material cutting bar, a material locking bar and rapid disassembly and assembly structures, a groove which extends in the direction of a long axis is formed in the upper end face of the material cutting bar, a material locking tooth set is arranged on the lower end face of the material locking bar, the material locking tooth set is composed of a plurality of material locking teeth which are distributed at equal intervals in the direction of the long axis of the material locking bar, one end of the material locking bar is connected with one end of the material cutting bar through one corresponding rapid disassembly and assembly structure, and the other end of the material locking bar is connected with the other end of the material cutting bar through the other rapid disassembly and assembly structure. According to the material cutting tool for the SMD diode, a semi-finished SMD diode is placed in the groove of the material cutting bar, the material locking bar is locked on the material cutting bar through the rapid disassembly and assembly structures, a chip is fixed and can not move under the limiting action of the material locking bar and the material cutting bar, and then the chip is prevented from moving after cutting; in addition, due to the fact that a 45-55% thickness difference exists between the material locking bar and the material cutting bar, during the design of materials to be cut and pin pressing equipment, the position of a front pin of the diode and the position of a rear pin of the diode can be distinguished according to the thickness difference, the situation that normal preceding of the subsequent processes is influenced by position reversing caused by repeated overturning is avoided, the working efficiency is improved, and the percent of pass of products is improved.

Description

technical field [0001] The invention relates to a chip diode cutting tool, in particular to a chip diode cutting tool with good cutting and foot pressing effects. Background technique [0002] In the manufacturing process of chip diodes, such as figure 1 As shown, the chip diode semi-finished product includes the packaged chip 6 and the pin 7 protruding from both ends of the chip 6, and the pin 7 is flattened near the chip 6; Pin presser. The traditional method is to directly place a row of SMD diode semi-finished products directly in a pair of beading bars, and then fix them in the mold of the cutting machine, and use the punching die to remove the redundant pins. The disadvantage is that the pins are punched Finally, because the plastic-encapsulated runner 8 between the pins connecting the semi-finished diodes is cut off; therefore, during the subsequent presser foot process, the semi-finished product may be displaced, which affects the manufacturing quality.
