Electronic component cutting machine construction and correction method thereof

The invention relates to an electronic component cutting machine, in particular to an electronic component cutting machine structure and a correction method which can conveniently and quickly complete the zero point correction of the electronic component cutting machine and effectively prevent the bottom surface of the cutter from being cracked during the calibration.

According to the electronic product, a plurality of active components and passive components cooperate to form a normal operation, and passive components such as inductors, resistors, and capacitors receive power, store or consume energy, and then use a transistor or an integrated circuit. Perform operations and operations with active components such as displays.

The process of the wafer type passive component is mainly that a plurality of passive components are first formed on an unsintered ceramic plate, and the passive component ceramic plate is cut by an electronic component cutter to separate the plurality of passive components. Passive components, followed by sintering, electrode fabrication and plating, testing and other processes.

The existing electronic component cutting machine is mainly set up on the electronic component cutting machine to set up a body, and the seat body and the motor screw set are assembled, and then the cutter is fixed under the seat body, when the passive component ceramic plate is to be cut. The passive component ceramic plate is placed on the base of the electronic component cutting machine, and then the motor is started to cause the motor to actuate the screw to lower the base body, and then the cutter set under the seat body will be the passive component ceramic plate. For cutting, the reciprocating cutting process is performed to cut the passive component ceramic plate into a square shape.

In order to make the cutter cut the passive component ceramic plate, it can just happen The ceramic plate of the passive component is cut off, and the deeper collision with the underlying abutment does not occur, causing passivation or cracking of the cutter. Therefore, before the cutting operation of the electronic component cutting machine, the correction of the cutter feed must be performed. The action is such that the depth of the cutter feed can be stopped just on the table top of the abutment, and the zero point calibration work is generally performed by a technician with many years of experience to slowly move the motor in a visual manner, so that the motor drives the seat body and cuts The knife descends to the abutment, stops the motor when the cutter just reaches the base table, and then inputs the position of the lower starting point into the motor record, and the cutter is assembled by the traditional electronic component cutting machine, which is firmer than two points. Locked to the seat body, the cutter's retractable margin is used as a buffer, so it must be very accurate in visual inspection, otherwise the cutter will easily hit the base table and passivate or crack. Therefore, the technical experience of the corrector is relatively important. Therefore, the operator must pay the salary of the corrector in particular, which causes a burden on personnel costs, and the conventional calibration method is slow and time consuming, and the electronic component cutting machine cannot be started during this slow correction. The operation also caused losses in the production of the industry.

Therefore, the present inventors have in view of the above-mentioned many shortcomings in the process of correcting the current electronic component cutting machine, and have been researching and creating the present invention by many years of ingenuity in the related fields of manufacturing and design experience and knowledge. .

The invention relates to an electronic component cutting machine structure and a calibration method thereof. The object of the invention is to provide a technique for conveniently and quickly completing the zero point correction of the electronic component cutting machine and effectively preventing the bottom surface of the cutter from being cracked.

In order to achieve the above-mentioned implementation object, the inventors have studied the following electronic component cutting machine structure and its calibration method, which is mainly for the movable body assembly body of the electronic component cutting machine, and then the transmission rod is set on the seat body, and The transmission rod is assembled with a servo motor fixed to the body, and is pivotally connected to the cutter at the bottom side of the base.

Therefore, when performing the correction, the steps include the following: A. setting the torque mode: setting the servo motor to the torque mode, and reducing the torque of the servo motor, and then starting the servo motor to drive the transmission rod Rotate at a constant speed so that the seat body assembled with the transmission rod and the cutter pivotally connected to the seat body are fed at a constant speed downward; B. Reading the feedback signal: driving the seat body and the cutter at the servo motor When the speed is fed, the servo motor will feedback the signal of the time and the feed distance at the same time. At this time, the time is proportional to the feed distance; C. The abnormal signal display: when the servo motor drives the block on the base When the knife touches the base table below, the servo motor does not have enough power to drive the cutter to continue the feed displacement. At this time, the signal sent back by the servo motor and the feed distance will be abnormal, which will increase with time. The feed distance is maintained at a fixed value; D. The zero point correction value is obtained: the feed distance value of the fixed value fed back by the servo motor is the optimum feed depth of the electronic component cutter.

According to this, the zero point correction of the electronic component cutting machine can be conveniently and quickly completed, and the pivoting structure of the cutter and the seat body can be utilized to generate the adjustment buffering effect during the correction, thereby preventing the bottom surface of the cutter from hardly hitting the base table, thereby causing The situation in which the cutter is cracked.
