For example, for cutting the chip resistor, a machining program is preset. Of course, in other embodiments, the method can also be used for cutting chip capacitors and other products.

Firstly, pulling out the sliding table 1082, placing the stacked chip resistors into the two limiting side plates 1083 and positioning the stacked chip resistors on the material supporting plate 1084; and then the sliding table 1082 is pushed back to the original position, and at the moment, the lock catch 133 and the locking device 132 are locked with each other, so that the sliding table 1082 is fixed, and the movement in the machining process is avoided.

During processing, the control device 102 controls the driving motor 10851 to work according to a preset program, and further drives the speed reducer 10852 to work, so as to drive the switching support plate 1086 to rise upwards, lift the material support plate 1084 and the chip resistor, the photoelectric correlation sensor 138 detects that the preset position is reached, the photoelectric correlation sensor 138 feeds back a signal to the control device 102, the control device 102 controls the driving motor 10851 to stop working, and controls the piston rod of the first lifting device 128 to extend downwards to the preset position, so as to lower the suction device 109 connected with the piston rod to the preset position, and suck the chip resistor, after suction, the control device 102 can be preset to control the piston rod of the first lifting device 128 to reciprocate upwards and downwards for several times, that is, the suction device 109 can shake upwards and downwards for several times, so that multiple chips of chip resistor can be sucked and shake off as much as possible, the phenomenon of material stacking is avoided as much as possible. After shaking for a predetermined number of times, the control device 102 controls the piston rod of the first lifting device 128 to retract and reset, so as to lift the suction device 109 to a predetermined position.

Then, the control device 102 controls the first actuator 126 to operate, the transport platform where the correction plate 117 is located is moved to a position right below the suction device 109 corresponding to the first lifting device 128, after the transport platform is in place, the control device 102 controls the first lifting device 128 to descend, controls the suction device 109 to stop vacuumizing, and simultaneously blows air to break vacuum on the suction device 109, so that the chip resistor falls onto the preheating heating plate 122 to bear the chip resistor.

Then, the control device 102 controls the driving device 119 to operate, and drives the linkage 118 to move, so as to drive the rotating shaft 1182 to rotate, thereby driving the four correction plates 117 to be synchronously combined to correct the position of the chip resistor.

After the calibration is completed, the control device 102 controls the first actuator 126 to operate, and resets the transport table on which the calibration board 117 is located, and moves to a position directly below the photosensor 139. In this process, the control device 102 also controls the heating rod 121 to be energized and heated to preheat the chip resistor.

When the photoelectric sensor 139 detects that the height of the chip resistor is inconsistent with the preset height, the control device 102 controls the alarm device 137 to give an alarm prompt; only when the heights are consistent, the control device 102 controls the first motor 1101 to work, so as to drive the first lifting mechanism 111 and the corresponding suction device 109 to move to a position right above the preheating heating plate 122, and to prepare for sucking the chip resistors for loading.

After the resistor is in place, the control device 102 controls the piston rod of the first lifting mechanism 111 to extend downwards to a preset position, and then the control device 102 controls the suction device 109 corresponding to the first lifting mechanism 111 to suck the chip resistor in a vacuum manner; after the suction is finished, for example, stopping for several seconds, and indicating that the suction is finished when the time is up; then, the control device 102 controls the piston rod of the first lifting mechanism 111 to return and retract;

next, the control device 102 controls the first motor 1101 to operate, and drives the first lifting mechanism 111 to a position right above the loading station corresponding to the stage 106. At this time, the control device 102 may also control the stage driving device 105 to operate at the same time, so as to convey the stage 106 to a feeding station predetermined at the rear; after both are in place;

the control device 102 controls the piston rod of the first lifting mechanism 111 to move downwards to reach a predetermined position, the control device 102 controls the suction device 109 to stop vacuumizing, and blows air to the suction device 109 to break vacuum, so that the chip resistor falls off from the suction device 109 and is carried by the carrier 106.

After the control device 102 controls the stage 106 to suck the chip resistor, the control device 102 moves and resets the stage driving device 105, and conveys the stage 106 to the lower side of the tool post 104, the control device 102 controls the tool post lifting device 131 and the stage driving device 105 to operate according to a predetermined program, and the dicing is completed.

After the cutting is completed, for example, the number of cuts can be preset, and when the preset number of cuts is completed, the cutting is completed.

Then, the control device 102 controls the stage driving device 105 to work, and conveys the stage 106 back to a predetermined feeding station;

at this time, also serving as a blanking station, the control device 102 controls the second motor 1121 to operate, and moves the second lifting mechanism 113 and the corresponding suction device 109 to a position right above the stage 106;

after the piston rod is in place, the control device 112 controls the piston rod of the second lifting mechanism 113 to extend downwards to a preset position; then controlling the suction device 109 to vacuumize and sucking the cut chip resistor; after the suction is finished, the piston rod of the second lifting mechanism 113 is controlled to reset and retract; finally, the second motor 1121 is controlled to move reversely, and the second lifting mechanism 113 and the suction device 109 are reset to move to the position right above the other stock bin 108; and then the piston rod of the second lifting mechanism 113 is controlled to extend downwards, the cut chip resistor is placed on the material supporting plate 1084 of the other stock bin 108, at this time, the control device 102 can also control the driving motor 10851 of the other stock bin 108 to work, the material supporting plate 1084 is lifted to a preset position to receive the material, and after the completion, the thickness of the chip resistor is reduced.

Whether the materials in the bin 108 are completely processed or fully stacked can be determined in various ways, for example, the processing times can be preset, a predetermined number of chip resistors are stacked in advance, the processing times are equal to the number of stacked chip resistors, and when the corresponding times are reached, the control device 102 controls the alarm device 137 to give an alarm prompt.
