In the specific implementation of the present embodiment, when the micrometer screw 231 is rotated, the thimble 231a extends out to push the distance-adjusting moving stage 22 away from the distance-adjusting fixing stage 21, so as to increase the distance between the distance-adjusting moving stage 22 and the distance-adjusting fixing stage 21, and further reduce the shearing length of the pins, and when the distance-adjusting moving stage 22 is pushed away from the distance-adjusting fixing stage 21, the distance-adjusting moving stage 22 extrudes the compression spring 233, so that the compression spring 233 exerts an opposite force on the distance-adjusting moving stage 22, and thus the distance-adjusting moving stage 22 can be fixed, and the distance-adjusting moving stage 22 is prevented from moving arbitrarily in the rib cutting process; when the micrometer screw 231 is rotated in the opposite direction, the thimble 231a is retracted, and the distance-adjusting moving table 22 can move towards the distance-adjusting fixed table 21 along the guide post 232 under the action of the pressure spring 233, so as to reduce the distance between the distance-adjusting moving table 22 and the distance-adjusting fixed table 21 and further increase the shearing length of the pins; the adjustment of the shearing length of the pin of the integrated circuit 100 is realized through the matching of the micrometer screw 231, the guide post 232 and the pressure spring 233, so that the pin of the integrated circuit 100 after being processed meets the processing requirement.
In this embodiment, a micrometer mounting hole 225c is further formed in the first mounting portion 225, and the micrometer screw 231 is detachably mounted in the micrometer mounting hole 225c by a bolt, so that the micrometer screw 231 can be easily mounted and dismounted. A guide post 232 assembling hole 21b is formed at a position of the distance adjusting fixed table 21 facing the distance adjusting movable table 22 and corresponding to the guide post sliding hole 225b, and the guide post 232 is detachably mounted in the guide post 232 assembling hole 21b through a bolt, so that the guide post 232 is conveniently mounted and dismounted.
It is understood that, in some embodiments, the distance adjusting mechanism 2 may only include one distance adjusting moving stage 22, and at the same time, the micrometer screw 231 and the guide post 232 are connected to the fixed blade set 11 to change the relative position between the integrated circuit 100 carried on the distance adjusting moving stage 22 and the fixed blade set 11, so as to adjust the pin shearing length.
A notch (not shown) is disposed above the distance adjusting mobile station 22 corresponding to the placing portion 3, and more specifically, a second mounting portion 226 is fixed on the table top of the placing station 31, and the notch is correspondingly disposed on the second mounting portion 226 and corresponds to a position above the placing portion 3. A circuit baffle 6 is fixed in the notch, and is used for fixing the integrated circuit 100 and limiting the shortest dimension after the pin of the integrated circuit 100 is cut, the shortest dimension is the length from the circuit baffle 6 to the edge of the first cutting surface 112b when the first inner concave surface 221a is attached to the corresponding surface of the fixed cutter group 11 and the second inner concave surface 223a is attached to the corresponding surface of the distance-adjusting fixing plate 431, and the shortest dimension is the smallest dimension which can be processed by the cutting tool. A gap for the pins of the integrated circuit 100 to pass through is formed between the circuit baffle 6 and the table top at the position corresponding to the distance adjusting mobile station 22, and the gap is the cutting window 32.
The second mounting portion 226 deviates from one side of the shearing mechanism 1 and is further provided with a protection plate 7 above the circuit baffle 6, so that an operator is prevented from touching the edge of the movable knife 122 or the fixed knife 112 during tendon cutting. In this embodiment, the second mounting portion 226 is provided with a protection plate mounting hole 226a, and the protection plate 7 is correspondingly mounted in the protection plate mounting hole 226a by a bolt.
When the invention works, firstly, according to the shearing requirement of the length of the pin, the micrometer screw 231 is rotated to extend the thimble 231a to push the distance-adjusting movable table 22 to the distance-adjusting fixed table 21, so as to adjust the distance between the distance-adjusting movable table 22 and the distance-adjusting fixed table 21 to the required position; then, the integrated circuit 100 to be cut is placed on the placing table 31 to abut against the circuit baffle 6, the integrated circuit 100 is held by hands to be fixed, and the pins penetrate through the cutting window to be flatly placed on the first cutting surface 112 b; then, the foot switch 54 is stepped on, the controller 51 detects that the foot switch 54 is closed, the two-position five-way valve 52 is controlled to drive the push rod 421 of the reciprocating cylinder 42 to move downwards, the movable knife 122 is further driven to move downwards to be close to the fixed knife 112, the pins exceeding the edge of the first shearing surface 112b are cut off under the matching of the first shearing surface 112b and the second shearing surface, the broken pin waste materials exit the shearing knife through the material returning groove 113 and the inclined surface, meanwhile, the cylinder magnetic switch 53 detects the position of the push rod 421 in the descending process of the push rod 421, the cylinder magnetic switch 53 stops moving when the push rod 421 moves downwards to the lower limit, the cylinder magnetic switch 53 sends a feedback signal to the controller 51, and the controller 51 controls the two-position five-way valve 52 to drive the push rod 421 of the reciprocating cylinder 42 to move upwards according to the feedback signal, so as to drive the movable knife 122 to be far away from the fixed knife 112; finally, the processed integrated circuit 100 may be removed from the mounting portion 3.
After the cutting is finished, if the cutting needs to be carried out on the pins of the other integrated circuits 100 according to the length again, the cutting operation is only needed to be repeated; if other lengths need to be cut, the distance between the distance adjusting movable table 22 and the distance adjusting fixed table 21 needs to be adjusted to the required width, then the cutting operation is executed, a specific cutter does not need to be replaced in the whole process, and the device is simple in structure and convenient to operate.
