Control system of integrated circuit tendon-cutting device

Abstract

The invention discloses a control system of an integrated circuit tendon-cutting device. The control system comprises a main controller and a vision detection device, wherein the main controller is provided with a control output end connected with a feeding device, a control output end connected with a driving mechanism of the tendon-cutting device and a control output end connected with a material receiving device. The invention has the advantages of simple control program and safe and reliable control, carries out vision detection on a tendon tablet to be cut so as to ensure that the direction and the model of the tendon tablet to be cut, which is fed into the tendon-cutting device, are correct and protect a tendon-cutting die, and carries out detection on the tablet subjected to tendon cutting so as to reflect the condition of the tablet subjected to the tendon cutting in time and reduce the emergence of an unfavorable tablet subjected to the tendon cutting.

Description

technical field [0001] The invention relates to a control system of an integrated circuit tendon cutting device. Background technique [0002] The rib cutting process of integrated circuits is one of the processes in the production process of integrated circuits, such as figure 1 Shown is a schematic diagram of the structure of an integrated circuit material before the ribs are cut after the integrated circuit is packaged. Before the ribs are trimmed, there are ribs connected between the pins of the integrated circuit. Because of the independence of the feet, there is a process of cutting ribs in the production process of integrated circuits. Ribbing is the removal of the metal that connects the pins of an integrated circuit. At present, the rib cutting process is completed by the integrated circuit rib cutting system. [0003] Such as figure 2 , is a structural schematic diagram of the existing integrated circuit tendon cutting device. In the tendon cutting device, an ...

Problems solved by technology

In a word, this existing integrated circuit rib cutting system has the following disadvantages: slow speed, low production capacity (50 punches per minute); large vibration, sudden stop due to rapid drop to the dead point of the mold, resulting in sudden change of inertia; hydraulic oil Leakage will cause product pollution; low production capacity, due to the incoherence of structural actions, logical actions must first complete one action before starting the second action; high energy consumption, hydraulic devices have many times of energy transfer due to large mechanical losses

The rib cutting process of integrated circuits uses an automatic rib cutting machine, which has fast rib cutting speed, high efficiency, and large production capacity. However, once the integrated circuit material is placed in the wrong direction or mixed with other integrated materials of different types It will cause rib cutting failure, thereby destroying the integrated circuit or damaging the rib cutting machine, so it is necessary to ensure that the direction of the integrated circuit material entering the rib trimming device is placed in the correct direction and conforms to the predetermined specifications, so as to avoid serious economic losses and time delays loss of working time

In order to solve this problem, most of the current methods use manual inspection. Not only that, but also in the process of cutting the ribs of the integrated circuit, manpower must be assigned to conduct random inspections on the products after the ribs are cut regularly to check whether the ribs are qualified. If there is a problem, the cutting device must be replaced in time or the cutting machine should be repaired accordingly, otherwise it will cause large-scale rework or even product scrap

However, the sampling inspection by manpower is slow and cannot reflect the situation after the integrated circuit is trimmed in time, and increases the manpower and financial costs of the enterprise
