Description

Technical Field

[0001] This utility model relates to the field of screw Phillips head slot cutting technology, and in particular to an automatic screw Phillips head slot cutting device. Background Technology

[0002] Currently, it is necessary to machine a Phillips head groove on the screw head. The Phillips head groove is used to cooperate with operating tools (such as screwdrivers). In existing screw Phillips head groove cutting devices, the cutting round cutter is usually controlled to rotate 90 degrees back and forth, so that the Phillips head groove can be cut on the screw one by one. That is, a slotted groove is first machined, and then the cutting round cutter rotates 90 degrees and machines the Phillips head groove on the basis of the slotted groove. This results in low efficiency and cannot meet the time limit requirements of mass production. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automatic screw Phillips head slot cutting device, in which a circular cutting blade can cut multiple screws at once, thereby improving production efficiency.

[0004] The automatic screw Phillips head slot cutting device according to a first aspect embodiment of the present invention includes:

[0005] The feeding mechanism includes a vibratory feeder and a transport track connected to each other, and the feeding mechanism is used to transport screws;

[0006] The clamping mechanism includes a mounting frame, multiple clamping modules, and a rotating motor. The top of the mounting frame is provided with a slide groove for supporting screws. The slide groove is connected to the transport track. The multiple clamping modules are rotatably mounted on the mounting frame and are located below the slide groove to clamp the screws in the slide groove. Each clamping module has an external gear on its outer periphery. An internal gear meshes between the external gears of two adjacent clamping modules. The rotating motor is used to drive one of the clamping modules to rotate, thereby driving the other clamping modules to rotate synchronously through the internal gear and the external gear.

[0007] The feeding mechanism includes a slide rail and a slider that are slidably connected to each other. The slide rail extends along the length of the groove and is fixed to the top of the mounting frame. The feeding mechanism also includes a drive device for driving the slider to slide. The feeding mechanism also includes a rotary motor, a feeding plate, a position sensor, and multiple sensors. The position sensor is in responsive engagement with the sensors and is also used to detect the position of the screws. The multiple sensors are fixed to the top of the mounting frame and correspond one-to-one with the positions of multiple clamping modules. The position sensor moves with the slider. The rotary motor is fixedly connected to the slider and is used to drive the feeding plate to rotate so that the feeding plate is inserted between two adjacent screws on the groove.

[0008] The cutting mechanism includes a cutting circular blade and a cylinder, wherein the cylinder is used to drive the cutting circular blade to reciprocate along the length of the slide groove.

[0009] The automatic screw Phillips head slotting device according to the present invention has at least the following beneficial effects: During operation, the vibratory feeder of the feeding mechanism sends the screw to the transport track, which in turn sends the screw to the slide groove of the mounting bracket. The drive device moves the slider, causing the slider to move the feeding plate to the screw position. Then, the rotary motor drives the feeding plate to insert into two adjacent screws. The position sensor can detect the screw position and the position of the sensing element. Based on the signal from the position sensor, the drive device is controlled to move the slider, causing the feeding plate to send the screws to the corresponding positions of multiple clamping modules one by one. Then, the multiple clamping modules clamp multiple screws respectively. Finally, the cylinder drives the cutting circular blade along the slide groove. The cutting circular cutter moves and cuts slotted grooves on multiple screws in a single movement. Then, the motor rotates one of the clamping modules by 90 degrees. Due to the meshing of the external and internal gears, the rotation of one clamping module drives the other clamping modules to rotate 90 degrees synchronously, thereby causing all the clamped screws to rotate 90 degrees. Then, the cylinder drives the cutting circular cutter to move along the slide to the initial position, thus machining a cross groove on the slotted grooves on the multiple screws. Then, the clamping module releases the screws, and the drive device drives the slider to move, causing the material-ejecting plate to remove all the screws in the slide, completing the unloading. The above steps can be repeated. The cutting circular cutter can cut multiple screws in one movement, which can greatly improve processing efficiency.

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] Reference Figure 1 As shown, an automatic screw Phillips head slot cutting device provided in this embodiment of the present utility model includes a feeding mechanism 100, a clamping mechanism 200, a feeding mechanism 300, and a cutting mechanism.

[0034] Reference Figures 1 to 6As shown, the unloading mechanism 100 includes a vibratory feeder 110 and a transport track 120 connected to each other, and the unloading mechanism 100 is used to transport screws 500. The clamping mechanism 200 includes a mounting frame 210, multiple clamping modules 220 and a rotary motor 230. The top of the mounting frame 210 is provided with a slide groove 211 for supporting the screws 500. The slide groove 211 is connected to the transport track 120. Multiple clamping modules 220 are rotatably mounted on the mounting frame 210. The clamping modules 220 are located below the slide groove 211 to clamp the screws 500 in the slide groove 211. Each clamping module 220 has an external gear 224 on its outer periphery. An internal gear 225 meshes between the external gears 224 of two adjacent clamping modules 220. The rotary motor 230 is used to drive one of the clamping modules 220 to rotate, thereby driving the other clamping modules 220 to rotate synchronously through the internal gear 225 and the external gear 224. The feeding mechanism 300 includes a slide rail 310 and a slider 320 that are slidably connected to each other. The slide rail 310 extends along the length of the groove 211 and is fixed to the top of the mounting frame 210. The feeding mechanism 300 also includes a rotary motor 330, a feeding plate 360, a position sensor 370, and multiple sensors 380. The position sensor 370 engages with the sensors 380 and is also used to detect the position of the screws 500. The multiple sensors 380 are fixed to the top of the mounting frame 210 and correspond one-to-one with the positions of the multiple clamping modules 220. The position sensor 370 moves together with the slider 320. The rotary motor 330 is fixedly connected to the slider 320 and is used to drive the feeding plate 360 ​​to rotate so that the feeding plate 360 ​​is inserted between two adjacent screws 500 on the groove 211. The cutting mechanism includes a cutting circular blade 400 and a cylinder. The cylinder is used to drive the cutting circular blade 400 to reciprocate along the length of the groove 211.

[0035] During operation, the vibratory feeder 110 of the feeding mechanism 100 delivers the screws 500 to the transport track 120, which in turn delivers them to the slide groove 211 of the mounting bracket 210. The drive unit moves the slider 320, causing it to move the feeding plate 360 ​​to the position of the screw 500. Then, the rotary motor 330 drives the feeding plate 360 ​​to insert into two adjacent positions. The position sensor 370 detects the position of the screw 500 and the position of the sensing element 380. Based on the signal from the position sensor 370, the drive unit is controlled to move the slider 320, causing the feeding plate 360 ​​to deliver the screws 500 one by one to the corresponding positions of the multiple clamping modules 220. The multiple clamping modules 220 then clamp the screws 500 respectively. Finally, the cylinder drives the cutting circular blade 400 to move along the slide groove 211. A single movement of the cutting blade 400 can cut slots on multiple screws 500. Then, the motor 230 rotates one of the clamping modules 220 by 90 degrees. Since the external gear 224 meshes with the internal gear 225, when one clamping module 220 rotates, it will drive the other clamping modules 220 to rotate 90 degrees synchronously, thereby driving all the clamped screws 500 to rotate 90 degrees. Then, the cylinder drives the cutting blade 400 to move along the slide 211 to the initial position, thereby machining a cross groove on the slots on the multiple screws 500. Then, the clamping module 220 releases the screws 500, and the drive device drives the slider 320 to move, so that the material-pulling plate 360 ​​pulls away all the screws 500 in the slide 211, completing the unloading. Then, the above steps can be repeated. The cutting blade 400 can cut multiple screws 500 in one movement, which can greatly improve the processing efficiency.

[0036] Reference Figure 3 As shown, in some embodiments, the feed plate 360 ​​is configured as an L-shaped plate, and there are two position sensors 370. The two position sensors 370 are fixed to the feed plate 360 ​​and are spaced 90 degrees apart from each other around the output shaft of the rotary motor 330. When the feed plate 360 ​​extends between the two screws 500, one position sensor 370 is on top and the other is on the bottom. The lower position sensor 370 detects the position of the screw 500, and the upper position sensor 370 detects the position of the sensing element 380. The two position sensors 370 can flexibly switch positions to detect either the position of the screw 500 or the position of the sensing element 380.

[0037] In some embodiments, the clamping module 220 is configured as a gripper cylinder, which is a cylindrical structure. The bottom of the mounting bracket 210 is provided with a through hole, and the gripper cylinder cooperates with the through hole. The bottom wall of the external gear 224 abuts against the inner wall of the mounting bracket 210 to support the gripper cylinder.

[0038] Reference Figure 4 As shown, in some embodiments, the gripper of the gripper cylinder is provided with a rubber pad 221. The rubber pad 221 is elastic and can prevent damage to the screw 500 when the gripper cylinder clamps the screw 500.

[0039] Reference Figure 5 As shown, in some embodiments, the clamping module 220 has a connecting shaft 222 at its bottom, the connecting shaft 222 has a first belt 350 pulley 223, the output shaft of the rotary motor 330 has a second belt 350 pulley 340, the first belt 350 pulley 223 and the second belt 350 pulley 340 are connected by a belt 350, and the rotary motor 330 is fixed on the mounting bracket 210.

[0040] In some embodiments, the position sensor 370 is configured as an optical distance sensor, an infrared distance sensor, or an ultrasonic distance sensor, and the sensing element 380 is used to reflect the signal emitted by the position sensor 370.

[0041] Reference Figure 4 As shown, in some embodiments, the outer diameter of the internal gear 225 is smaller than the outer diameter of the external gear 224, which can reduce the distance between two adjacent clamping modules 220 and reduce the space occupied.

[0042] Reference Figure 1 As shown, in some embodiments, the transport track 120 is provided with an inverted T-slot 121 for supporting the screw 500.
