[0001] The utility model belongs to the technical field of screw dividers, and in particular relates to a screw divider device. Background Art

[0002] As the most common assembly structure in daily life, screws have important tasks in industry. As long as there is industry on earth, screws are needed. Screws have been a common invention in people's production and life for thousands of years. In terms of application fields, it is the first invention of mankind. Screw sorting is one of the important links in screw locking. Traditional screw sorting is done by operators manually sorting or single screw sorting equipment picking up screws, which has low work efficiency.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. Embodiment 1

[0028] like Figure 1-Figure 4 As shown, the technical solution adopted by the utility model is as follows: a screw material dividing device, comprising a base plate 1 and screws 5, a plurality of supporting legs 2 are fixedly arranged at the bottom of the base plate 1, two guide plates 4 are arranged on the base plate 1, the guide plates 4 and the base plate 1 are fixedly connected by setting a bracket 3, the top of the bracket 3 is fixedly connected to the bottom of the guide plate 4, and the bottom of the bracket 3 is fixedly connected to the top of the base plate 1.

[0029] A guide groove 13 is left between the two guide plates 4 . The guide plate 4 is composed of an inclined plate and a horizontal plate. The inclined plate is aligned with the external feeding device. The inclined plate is the input end of the screw 5 , and the horizontal plate is the output end of the screw 5 .

[0030] The guide groove 13 is convex, and the top of the guide groove 13 limits the top of the screw 5 to prevent the screw 5 from falling. Two gears 6 are rotatably arranged below the guide plate 4, and the gap between the two gears 6 corresponds to the guide groove 13.

[0031] The screw 5 entering the guide groove 13 will slide downward along the direction of the inclined plate of the guide groove 13. When the screw 5 slides to the horizontal plate of the guide groove 13, the screw 5 will continue to slide along the direction of the guide groove 13 under its own inertia and the push of the screw 5 behind it, until the front end of the screw 5 enters between the two gears 6 and stops.

[0032] The top of the bottom plate 1 is rotatably provided with a loading tray 7, which is located below the gear 6. The loading tray 7 is provided with a plurality of blanking holes 8, which are distributed in a circumferential array. In addition, the screw 5 is plugged and matched with the blanking hole 8 through the guide groove 13 and the gear 6.

[0033] The bottom plate 1 is provided with an adjusting mechanism for driving the two gears 6 to rotate in opposite directions.

[0034] The adjustment mechanism includes a first motor 14, which is fixedly arranged at the bottom of the base plate 1. A rotating shaft 23 is fixedly arranged at the center bottom of the two gears 6, wherein the bottom of one rotating shaft 23 is fixedly connected to the output end of the first motor 14, and the bottom of the other rotating shaft 23 is fixedly arranged with a second synchronous gear 25. A second rotating shaft 26 is rotatably arranged at the bottom of the base plate 1, and a first synchronous gear 24 is fixedly sleeved on the circumferential surface of the second rotating shaft 26, and the first synchronous gear 24 is meshed with the second synchronous gear 25. A pulley 17 is sleeved on the second rotating shaft 26 and the rotating shaft 23 corresponding to the first motor 14, and a belt 16 is sleeved between the two pulleys 17.

[0035] When the first motor 14 is started, the output end of the first motor 14 drives the rotating shaft 23 connected thereto to rotate, thereby driving the corresponding pulley 17 and gear 6 to rotate. The rotation of the pulley 17 drives another pulley 17 to rotate through the belt 16, thereby driving the second rotating shaft 26 to rotate in the same direction.

[0036] The rotation of the second rotating shaft 26 drives the first synchronous gear 24 to rotate, and the rotation of the first synchronous gear 24 drives the second synchronous gear 25 to rotate in the opposite direction, and the rotation of the second synchronous gear 25 drives the rotating shaft 23 which is not connected to the first motor 14 to rotate, thereby driving another gear 6 to rotate, thereby achieving synchronous and opposite rotation of the two gears 6.

[0037] The two gears 6 rotate synchronously in opposite directions to drive the screw 5 to fall into the drop hole 8 on the loading tray 7, and then stop the first motor 14.

[0038] The bottom plate 1 is provided with a driving mechanism for driving the charging tray 7 to rotate.

[0039] The driving mechanism includes a second motor 15 , which is fixedly arranged at the bottom of the base plate 1 , and an output end of the second motor 15 passes through the base plate 1 , and the output end of the second motor 15 is fixedly connected to the central bottom of the loading tray 7 .

[0040] The second motor 15 is started, and the output end of the second motor 15 drives the loading tray 7 to rotate until the next blanking hole 8 is aligned with the screw 5 on the gear 6 and then stops.

[0041] Then gear 6 continues to rotate, and the cycle continues.

[0042] A conveying mechanism is provided on one side of the bottom plate 1 away from the guide plate 4 . A positioning hole 18 is provided on the bottom plate 1 . The conveying mechanism is matched with the blanking hole 8 through the positioning hole 18 .

[0043] The conveying mechanism comprises a conveyor belt 11 , on which a plurality of workpieces 9 are arranged, and on which assembly holes 10 are opened, and the assembly holes 10 correspond to and cooperate with the positioning holes 18 .

[0044] In the initial state, the assembly hole 10 on the workpiece 9 is aligned with the positioning hole 18. When the loading tray 7 drives the blanking hole 8 containing the screw 5 to pass through the positioning hole 18, the screw 5 will fall into the assembly hole 10 on the workpiece 9 through the positioning hole 18, thereby completing the assembly. Subsequently, the rotation of the loading tray 7 is stopped and the next workpiece 9 is aligned with the positioning hole 18 through the conveyor belt 11. Repeat the above operation.

[0045] How it works

[0046] When using the device, the staff aligns the guide groove 13 with the feeding device.

[0047] The guide groove 13 is convex in shape, and the top of the guide groove 13 limits the screw 5 to prevent the screw 5 from falling.

[0048] The screw 5 entering the guide groove 13 will slide downward along the direction of the inclined plate of the guide groove 13. When the screw 5 slides to the horizontal plate of the guide groove 13, the screw 5 will continue to slide along the direction of the guide groove 13 under its own inertia and the push of the screw 5 behind it, until the front end of the screw 5 enters between the two gears 6 and stops.

[0049] Next, the first motor 14 is started, and the output end of the first motor 14 drives the shaft 23 connected thereto to rotate, thereby driving the corresponding pulley 17 and gear 6 to rotate. The rotation of the pulley 17 drives another pulley 17 to rotate through the belt 16, thereby driving the second shaft 26 to rotate in the same direction.

[0050] The rotation of the second rotating shaft 26 drives the first synchronous gear 24 to rotate, and the rotation of the first synchronous gear 24 drives the second synchronous gear 25 to rotate in the opposite direction, and the rotation of the second synchronous gear 25 drives the rotating shaft 23 which is not connected to the first motor 14 to rotate, thereby driving another gear 6 to rotate, thereby achieving synchronous and opposite rotation of the two gears 6.

[0051] The two gears 6 rotate synchronously in opposite directions to drive the screw 5 to fall into the drop hole 8 on the loading tray 7, and then stop the first motor 14.

[0052] The second motor 15 is started, and the output end of the second motor 15 drives the loading tray 7 to rotate until the next drop hole 8 is aligned with the screw 5 on the gear 6 and stops. Then the gear 6 continues to rotate, and the cycle continues.

[0053] In the initial state, the assembly hole 10 on the workpiece 9 is aligned with the positioning hole 18. When the loading tray 7 drives the blanking hole 8 containing the screw 5 to pass through the positioning hole 18, the screw 5 will fall into the assembly hole 10 on the workpiece 9 through the positioning hole 18, thereby completing the assembly. Subsequently, the rotation of the loading tray 7 is stopped and the next workpiece 9 is aligned with the positioning hole 18 through the conveyor belt 11. Repeat the above operation. Embodiment 2

[0054] Compared with the first embodiment, in this embodiment, an integrated driving mechanism for driving the two gears 6 to rotate in opposite directions or the loading tray 7 to rotate is provided at the bottom of the bottom plate 1 .

[0055] The integrated drive mechanism includes a third motor 22, which is fixedly arranged at the bottom of the base plate 1, and a toothless gear 21 is fixedly arranged at the output end of the third motor 22, and the toothless gear 21 is rotatably connected to the base plate 1. A first gear 19 and a second gear 20 are correspondingly arranged at the bottom of the two rotating shafts 23, and both the first gear 19 and the second gear 20 are meshed with the toothless gear 21.

[0056] Start the third motor 22, and the output end of the third motor 22 will drive the toothless gear 21 to rotate. When the toothless gear 21 is engaged with the No. 1 gear 19, the No. 1 gear 19 will drive the rotating shaft 23 corresponding to the gear 6 to rotate, thereby driving the two gears 6 to rotate synchronously in the opposite direction, thereby driving the screw 5 to enter the blanking hole 8.

[0057] When the toothless gear 21 meshes with the second gear 20, the second gear 20 rotates, thereby driving the rotating shaft 23 corresponding to the loading tray 7 to rotate, thereby driving the loading tray 7 to rotate. Then, the screw 5 is dropped onto the workpiece 9 below through the positioning hole 18 to complete the assembly.

[0058] How it works

[0059] Compared with the first embodiment, the driving source for driving the gear 6 and the loading tray 7 is the same. The third motor 22 is started, and the output end of the third motor 22 drives the toothless gear 21 to rotate. When the toothless gear 21 is meshed with the first gear 19, the first gear 19 drives the rotating shaft 23 corresponding to the gear 6 to rotate, thereby driving the two gears 6 to rotate synchronously in the opposite direction, thereby driving the screw 5 to enter the blanking hole 8.

[0060] When the toothless gear 21 meshes with the second gear 20, the second gear 20 rotates, thereby driving the rotating shaft 23 corresponding to the loading tray 7 to rotate, thereby driving the loading tray 7 to rotate. Then, the screw 5 is dropped onto the workpiece 9 below through the positioning hole 18 to complete the assembly.
