The turntable 201 is provided with a plurality of position sensors 205. The plurality of position sensors 205 are used to detect one by one whether there are screws 600 in the plurality of adsorption holes 202, thereby determining whether to discharge the adsorption holes 202.

[0042] Reference Figure 1 and Figure 10 As shown, the slotting mechanism 300 includes a moving mechanism 301 and a cutting circular blade 302. The cutting circular blade 302 is located at the bottom of the turntable 201. The moving mechanism 301 is used to drive the cutting circular blade 302 to move in the horizontal direction to process a slot on the screw 600 on the suction hole 202.

[0043] Reference Figure 1 and Figure 10 As shown, according to some embodiments of the present invention, the automatic screw slotting device 1000 includes a cooling mechanism 400.

[0044] Reference Figure 9 and Figure 10 As shown, according to some embodiments of this utility model, the turntable 201 has multiple suction channels 206 inside, and each suction channel 206 is equipped with a first switching valve 208. The first switching valve 208 is used to open or close the suction channel 206. The multiple suction channels 206 are connected to multiple adsorption holes 202 one by one. The end face of the turntable 201 is provided with a connecting pipe 212 that communicates with the multiple suction channels 206. The vacuum pump 213 is fixed to the end face of the turntable 201 and connected to the connecting pipe 212. With this arrangement, each adsorption hole 202 can be precisely controlled.

[0045] Reference Figure 9 and Figure 10As shown, according to some embodiments of the present invention, the turntable 201 is also provided with multiple venting channels 207.

[0046] Reference Figure 9 and Figure 10 As shown, according to some embodiments of the present invention, the turntable 201 includes a first disc portion 210 and a second disc portion. The first disc portion 210 and the second disc portion have the same structure. An air intake channel 206 is formed between the first disc portion 210 and the second disc portion. Multiple mounting cavities 211 are located between the first disc portion 210 and the second disc portion. Multiple position sensors 205 are correspondingly mounted in the multiple mounting cavities 211. The multiple mounting cavities 211 are respectively connected to multiple adsorption holes 202. The position sensors 205 are arranged inside the turntable 201 to prevent coolant from splashing onto the position sensors 205 during the cooling process.

[0047] Reference Figure 10 As shown, according to some embodiments of the present invention, the cutting direction of the cutting circular blade 302 is parallel to the axis of the turntable 201. This arrangement makes it less likely for the cutting circular blade 302 to drive the turntable 201 to rotate.

[0048] Reference Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, the inner wall of the adsorption hole 202 is provided with clearance grooves 203 on both sides along the axis of the turntable 201. The clearance grooves 203 are used to avoid the cutting circular blade 302, so that the cutting circular blade 302 can fully process the slot.

[0049] Reference Figure 5 As shown, according to some embodiments of the present invention, a guide tube 107 is provided at the bottom of the feeding hole 106. The guide tube 107 extends in the vertical direction and can guide the screw 600 into the adsorption hole 202 in the vertical direction, ensuring that the screw 600 is fed into place.

[0050] Reference Figure 8 As shown, according to some embodiments of the present invention, a sealing ring 204 is provided at the upper end of the adsorption hole 202. The sealing ring 204 is used to cooperate with the screw head of the screw 600, which can play a sealing role, improve air tightness, prevent air leakage, and also prevent coolant from splashing into the adsorption hole 202 during the cooling process.

[0051] Reference Figure 1As shown, according to some embodiments of the present invention, the automatic screw slotting device 1000 further includes a collection guide rail 500 and a collection box 501. The collection guide rail 500 is correspondingly arranged with one of the adsorption holes 202 to collect the screws 600 in the adsorption holes 202 into the collection box 501.

[0052] When the automatic slotting machine 1000 is working, the vibratory feeder 101 transports multiple screws 600 to the inclined track 102. Under the action of gravity, the inclined track 102 automatically slides downwards. Figure 4 As shown, the first limiting plate 108 and the second limiting plate 110 block the screw 600. When material needs to be unloaded, the first driving device 109 drives the first limiting plate 108 to rotate, releasing the screw 600 between the first limiting plate 108 and the second limiting plate 110. Under the action of gravity, the screw 600 slides to the unloading hole 106, and then slides down into the guide tube 107. The screw 600 then falls into the suction hole 202 of the turntable 201. The vacuum pump 213 continues to work, and the first switching valve 208 of the turntable 201 opens simultaneously. When the second switch valve 209 closes, a negative pressure is generated in the suction hole 202, which attracts and fixes the screw 600. The screw head of the screw 600 abuts against the sealing ring 204 to ensure airtightness and prevent leakage. Then, the first drive device 109 drives the first limit plate 108 back into the first groove 104, and the second drive device 111 drives the second limit plate 110 to release the screw 600, leaving one screw 600 between the first limit plate 108 and the second limit plate 110. Then, the second drive device 111 drives the second limit plate 110 back into the second groove. Within 105, the screw 600 is blocked, and then the drive mechanism drives the turntable 201 to rotate. A new suction hole 202 aligns with the feeding hole 106, and the feeding process continues. When the turntable 201 moves the screw 600 to the position of the cutting blade 302, the moving mechanism 301 drives the cutting blade 302 to move along the axis of the turntable 201, causing the high-speed rotating cutting blade 302 to cut a slot on the screw 600. Due to the high-speed friction between the cutting blade 302 and the screw 600, heat is generated, and the nozzle 402 can direct heat towards the cutting blade. The blade 302 sprays coolant to achieve a cooling effect. At the same time, the coolant can be collected in the reservoir 401 and transported to the nozzle 402 by the circulation pump, thus realizing recycling. Finally, the turntable 201 moves the screw 600 with the slotted groove processed to the collection guide rail 500. At this time, the first switch valve 208 is closed and the second switch valve 209 is opened. The negative pressure in the suction hole 202 disappears, realizing the release of air. This allows the screw 600 to fall down onto the collection guide rail 500 and be collected by the collection box 501.

[0053] This embodiment mainly uses an adsorption mechanism 200 to adsorb and fix the screw 600. The vacuum pump 213 provides the pneumatic power to adsorb the screw 600, which replaces the traditional method of clamping the screw 600 with a clamp. This can avoid damage to the external thread of the screw 600. In addition, a feeding mechanism is designed to match the turntable 201 of the adsorption mechanism 200 for feeding, which can realize feeding one by one, ensure feeding stability, and prevent the screw 600 from falling to the outside.
