When the first and second anti-reflection baffles 23 and 24 are relatively opened, the first and second material dividing baffles 26 and 29 are relatively closed; when the first and second anti-reflection baffles 23 and 24 are relatively closed, the first and second material dividing baffles 26 and 29 are relatively opened; the first anti-reflection baffle 23 and the first material dividing baffle 26 are located on the same side of the material dividing seat 22, and the first anti-reflection baffle 23 and the first material dividing baffle 26 are respectively installed on one side of the outer cover 28 through the first spring 231 and the second spring 261 in cooperation with the first mounting plate 281; the second anti-reflection baffle 24 and the second material dividing baffle 29 are located on the other side of the material dividing seat 22, and the second anti-reflection baffle 24 and the second material dividing baffle 29 are respectively installed on the other side of the outer cover 28 through the third spring 241 and the fourth spring 291 in cooperation with the second mounting plate 282.

[0027] The discharge hole 222 is tilted from top to bottom, which can ensure that the screws are discharged stably from the discharge hole 222 .

[0028] The cam driving module 27 includes a cam driving frame 271 installed on the bottom plate 21 and capable of extending into the outer side of the material distributing seat 22 to drive the first and second anti-reflection baffles 23, 24 to open or close relative to each other and to drive the first and second material distributing baffles 26, 29 to close or open relative to each other, a cam seat 272 installed on the bottom plate 21 and connected to the cam driving frame 271 and used to drive the front of the wheel driving frame 271 to move back and forth, and a power device 273 installed on the lower end of the bottom plate 21 and used to drive the cam seat 272 to rotate.

[0029] The cam drive frame 271 has a first drive rod 201 and a second drive rod 202 symmetrically arranged, and a third drive rod 203 and a fourth drive rod 204 located above the first drive rod 201 and the second drive rod 202 and staggered with the first drive rod 201 and the second drive rod 202, the third drive rod 203 and the fourth drive rod 204 are symmetrically arranged; the first drive rod 201 and the second drive rod 202 are in contact with the first anti-reflection baffle 23 and the second anti-reflection baffle 24 respectively; the third drive rod 203 and the fourth drive rod 204 are in contact with the first material distribution baffle 26 and the second material distribution baffle 29 respectively. Specifically, the first driving rod 201 and the second driving rod 202 are respectively provided with a first driving groove 205 and a second driving groove 206 on their outer sides, the first anti-reflection baffle 23 and the second anti-reflection baffle 24 are respectively provided with a first rolling element 232 and a second rolling element, and the first and second rolling elements are respectively placed in the first and second driving grooves 205 and 206; the third driving rod 203 and the fourth driving rod 204 are respectively provided with a third driving groove 207 and a fourth driving groove 208 on their outer sides, the first material dividing baffle 26 and the second material dividing baffle 29 are respectively provided with a third and fourth rolling elements 262 and 292, and the third and fourth rolling elements 262 and 292 are respectively placed in the third and fourth driving grooves 207 and 208. Among them, when the third and fourth rolling elements 262 and 292 fall into the third and fourth driving grooves 207 and 208, the first and second material dividing baffles 26 and 29 are relatively closed. At this time, the first and second rolling elements are respectively placed in the first and second driving grooves 205 and 206 and do not fall into the first and second driving grooves 205 and 206, and the first and second anti-reflection baffles 23 and 24 are relatively opened.

[0030] The first, second, third and fourth rolling members are any one of rollers or bearings, which can ensure that the cam driving frame 271 forms rolling contact with the first and second anti-reflection baffles 23, 24 and the first and second material dividing baffles 26, 29, which can effectively avoid wear and tear, and can ensure that the cam driving frame 271 can stably drive the first and second anti-reflection baffles 23, 24 to open or close relatively and drive the first and second material dividing baffles 26, 29 to close or open relatively, thereby improving work quality and work efficiency.

[0031] A connecting bearing 274 is installed on the cam seat 272 , and the connecting bearing 274 is placed in a strip-shaped driving groove 209 provided at the rear end of the cam driving frame 271 .

[0032] The power device 273 is a servo motor, which can ensure the stability and working accuracy of the material distribution mechanism.

[0033] A material baffle plate 3 with adjustable relative height is installed on the upper end surface of the outer cover 28, and the material baffle plate 3 is located above the first material dividing groove 221 and the material discharge hole 222, so as to prevent the screw from escaping from the first material dividing groove 221 and the material discharge hole 222 when passing through the first material dividing groove 221 and the material discharge hole 222, thereby ensuring the working effect and quality of the material dividing.

[0034] The baffle plate 3 is mounted on a height adjustment seat 31, which contacts the upper end surface of the outer cover 28 via a height adjustment spring, and is connected to the upper end surface of the outer cover 28 via a screw 311, and the screw 311 passes through the height adjustment spring.

[0035] When the present invention is working, one screw after another enters along the first material groove 111 of the material rail and accumulates in the first material groove 221 of the material distribution seat 22 in the material distribution mechanism 2. The cam driving module 27 in the material distribution mechanism drives the first and second anti-reverse baffles 23 and 24 to be relatively closed, and the first and second material distribution baffles 26 and 29 to be relatively opened; at this time, the first and second anti-reverse baffles 23 and 24 block the screw to prevent the screw from turning over and reversing, thereby ensuring the correct direction of the screw transmission; then, the cam driving module 27 moves in the reverse direction to drive the first and second anti-reverse baffles 23 and 24 to be relatively opened. At this time, a screw passes through the first and second anti-reverse baffles The plates 23 and 24 enter the discharge hole 222. Since the first and second material dividing baffles 26 and 29 are slowly relatively closed, the first and second material dividing baffles 26 and 29 clamp the screws, and the nuts of the screws are stuck above the first and second material dividing baffles 26 and 29. Then, the cam driving module 27 in the material dividing mechanism drives the first and second anti-reflection baffles 23 and 24 to be relatively closed to block the next screw, and the first and second material dividing baffles 26 and 29 are relatively opened, so that the screws originally clamped by the first and second material dividing baffles 26 and 29 fall into the discharge hole, and the above actions are repeated continuously to achieve the purpose of material dividing.

[0036] To sum up, the present invention has a simple structure and can prevent the screws from being skewed and reversed during the transmission process and causing the material to get stuck. Each screw used for material separation in the present invention will not flip over, ensuring the correct direction and achieving the purpose of accurate material separation, thereby ensuring the work quality and work efficiency of material separation, making the present invention extremely competitive in the market.

[0037] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
