Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a technical solution: comprising a base assembly 1, a flattening limit assembly 2 is fixedly installed on both sides of the top of the base assembly 1, a cutting assembly 3 is arranged above the base assembly 1, the base assembly 1 comprises a collecting base 101 and a collecting cavity 102, a collecting cavity 102 is provided on the top surface of the collecting base 101, a guiding inclined plate 103 is arranged at the rear of the collecting cavity 102, a cutting plate 104 is fixedly installed on the top of the collecting base 101, an empty slot is provided on the front of the cutting plate 104, a No. 1 screw 105 is rotatably installed in the empty slot, and a blanking plate 107 is fixedly installed on the back of the cutting plate 104;

[0021] The flattening limit assembly 2 includes a vertical plate 201 and an L-shaped slide bar 202, an L-shaped slide bar 202 is fixedly installed on the back of the vertical plate 201, a through-type threaded hole 203 is opened on a side of the horizontal protruding end of the L-shaped slide bar 202, a vertical groove 204 is opened in the middle of the back of the vertical plate 201, a No. 2 screw 205 is rotatably installed in the vertical groove 204, a threaded connection block 206 is slidably installed in the vertical groove 204, and the threaded connection block 206 is threadedly sleeved on the No. 2 screw 205, a mounting plate 207 is slidably installed on the inner side surface of the vertical plate 201, the bottom of the outer side surface of the mounting plate 207 is fixedly connected to a side surface of the threaded connection block 206, and a plurality of pressure wheels 208 are rotatably installed on the inner side surface of the mounting plate 207;

[0022] The vertical plate 201 is slidably mounted on the top surface of the cutting plate 104 , the horizontal protruding end of the L-shaped slide bar 202 is slidably mounted in the empty groove, and the L-shaped slide bar 202 is threadedly sleeved on the No. 1 screw rod 105 through the threaded hole 203 .

[0023] In this embodiment, the cutting assembly 3 includes a mounting frame 301 and a cylinder 302. A cylinder 302 is fixedly installed at the center of the top surface of the mounting frame 301. One end of the output shaft of the cylinder 302 passes through the bottom surface of the top plate of the mounting frame 301 and is fixedly installed with a lifting plate 303.

[0024] At the same time, a cutting blade 304 is fixedly installed on the bottom surface of the lifting plate 303. The cutting blade 304 is located just above the cutting notch 106. The cutting blade 304 is driven down by the cylinder 302 so as to cut the lead sheet.

[0025] The plurality of pressing wheels 208 are evenly spaced and arranged at equal distances. The four feet of the mounting frame 301 are grouped in two, and each group of feet is fixedly mounted on one side of the collecting base 101. The pin sheet on the cutting plate 104 can be fixed by controlling the pressing wheel 208 to descend.

By controlling the descent of the pressure wheels 208, the pin piece on the cutting plate 104 can be fixed. When cutting, only an external air supply is required. The cylinder 302 drives the cutting blade 304 to descend, so that the pin sheet can be cut. The cut single-row pins will fall onto the guide inclined plate 103 provided in the collection chamber 102 under the action of the blanking plate 107. Under the action of the guide inclined plate 103 provided in the collection chamber 102, the single-row pin sheet will slide to the front of the collection chamber 102, and then the staff can conveniently collect the cut single-row pin sheet from the front of the collection chamber 102.

[0028] To sum up, the micro switch cutting device can flatten the edge of the pin piece without affecting the movement of the pin piece by setting a flattening limit component, effectively preventing the edge of the pin piece from warping or the entire pin piece from being offset during the cutting process, resulting in cutting failure. It improves the cutting efficiency and the cutting accuracy at the same time. At the same time, the cut single-row pin pieces can be easily entered into the collection chamber under the action of the blanking plate and the guide inclined plate, which is convenient for subsequent centralized collection.
