Description

Technical Field

[0001] The present invention relates to the technical field of screw processing, and particularly relates to a feeding device for multi-size adjustable screw processing and a using method thereof. Background Art

[0002] Screw: a cylinder with spiral grooves cut on its outer surface or a cone with conical spiral grooves cut on it. The screw has different heads, and the head is called an external hexagon screw. There are also others, such as large flat screws, internal hexagon screws, etc. Existing screw processing equipment does not have a feeding function, and generally, workers are required to feed the materials. However, manual feeding has too low efficiency.

[0003] In the screw processing feeding device disclosed in the Chinese Patent Application Publication Specification CN216917299U, although the device makes the size of the clamping space between the two clamping wheels adaptable to screws of different sizes by using the adsorption or repulsion force of the first magnetic member and the second magnetic member, and cooperating with the support frame elastically installed in the installation box, and a similar elastic contact is formed between the clamping wheel and the screw to be processed, which improves the screw processing efficiency. However, the existing device does not solve the problems that during the screw processing, it is necessary to manually place the screws into the equipment one by one, which is time-consuming and laborious. When feeding the screws, due to the different diameters of screws of different sizes, the processing methods are also different, and it is impossible to distinguish and feed screws of different diameters, resulting in difficulties in subsequent screw processing. When feeding screws with shorter lengths, since the length inside the supply box 9 is longer while the required feeding screw length is shorter, multiple screws are placed side by side, easily causing multiple screws to be transported simultaneously during the screw transportation, resulting in difficulties in subsequent processing. Screws of different types also have different lengths. When feeding screws of different lengths, there are easily multiple screws of different lengths during the feeding process, and it is time-consuming and laborious for workers to classify screws of different lengths. Moreover, when screws of different lengths are fed simultaneously, since the processing processes of screws of different lengths are also different, it is easy to cause troubles in the subsequent processing process. Therefore, the present application provides a feeding device for multi-size adjustable screw processing and a using method thereof to meet the requirements. Summary of the Invention

[0014] A multi-size adjustable screw processing and feeding device and its usage method include the following steps: Step 1: First, place the required transport screws into the docking box. Multiple screws move along the slope towards the auxiliary plate. The auxiliary plate is moved upward by the auxiliary hydraulic device, so that the screws move outward. The removed screws are intercepted by the positioning clamp. The two positioning clamps are driven simultaneously by the positioning double-headed motor to clamp the screws. Step 2: The fixed clamp is moved downward by the moving hydraulic device. The clamp lead screw is driven by the clamp motor to make the moving clamp move parallelly, so that the fixed clamp and the moving clamp clamp and fix the screw. Then the fixed clamp and the screw are moved upward by the moving hydraulic device. Then the moving lead screw is driven by the moving motor to make the moving slider drive the screw to move parallelly. When the screw passes through the first group of limit seats and the collision sensors but does not touch them, the moving screw continues to move until the surface of the screw touches the collision sensor. The clamp lead screw is driven by the clamp motor to make the moving clamp move parallelly to reset, so that the screw falls into the corresponding storage box, and thus the screws can be classified, placed and collected according to their different lengths. Step 3: The two supply lead screws are driven simultaneously by the supply double-headed motor to make the two limit plates move in opposite directions until they are slightly longer than the required feeding screw length. Then the required feeding screw is placed into the supply box. Step Four: Place the screw inside the supply box. Use the fixed hydraulic device to move the fixed plate and the placement rack upward. Lift the screw inside the supply box through the groove on the upper surface of the placement rack. After lifting, use the connecting hydraulic device to move the screw towards the transport rack. The screw moves between the active transport wheel and the auxiliary transport wheel. Step Five: Finally, drive the active wheel through the transport motor. Since the active wheel rotates, the active belt drives the driven wheel to rotate. At the same time, since the driven wheel rotates, the auxiliary belt can drive the remaining driven wheels to rotate. Through the rotation of the active wheel and the driven wheel, the active transport wheel and the auxiliary transport wheel can rotate, which can drive the screw to continue moving. Then, dock the required feeding structure with the outlet position of the transport rack to complete the feeding operation during screw processing. Step Six: When the screw diameters inside the supply box are different but need to be transported to the same position, use the docking hydraulic device to move the docking rack upward. Use the fixed hydraulic device to move the placement rack upward. The docking rack lifts one screw. After lifting, use the connecting hydraulic device to move the screw towards the transport rack. After the screw moves between the active transport wheel and the auxiliary transport wheel, drive the active wheel through the transport motor. Since the active wheel rotates, the active belt drives the driven wheel to rotate. At the same time, since the driven wheel rotates, the auxiliary belt can drive the remaining driven wheels to rotate. Through the rotation of the active wheel and the driven wheel, the active transport wheel and the auxiliary transport wheel can rotate, which can drive the screw to continue moving. Then, dock the required feeding structure with the outlet position of the transport rack to complete the operation of transporting screws with different diameters. Step Seven: When the screw diameters inside the supply box are different and need to be transported separately, use the docking hydraulic device to move the docking rack downward to reset. Use the fixed hydraulic device to move the placement rack upward. As a result, the screw with the smallest diameter falls into the lowest card slot on the upper surface of the placement rack, the screw with a larger diameter falls into the card slot near the middle of the placement rack, and the screw with the largest diameter falls into the card slot near the upper part of the placement rack. Then, use the fixed hydraulic device to move the placement rack upward to lift all three screws with different diameters. After lifting, use the connecting hydraulic device to move the screws towards the transport rack. After the screws move between the active transport wheel and the auxiliary transport wheel, drive the active wheel through the transport motor. Since the active wheel rotates, the active belt drives the driven wheel to rotate. At the same time, since the driven wheel rotates, the auxiliary belt can drive the remaining driven wheels to rotate. Through the rotation of the active wheel and the driven wheel, the active transport wheel and the auxiliary transport wheel can rotate, which can drive the screws to continue moving, thus completing the separate transportation of screws with different diameters.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, through the provided supply box, the fixed hydraulic device is used to move the fixed plate and the placement rack upward. The screw inside the supply box is lifted by the groove on the upper surface of the placement rack. After being lifted, the screw is moved towards the transport rack by the connecting hydraulic device. After the screw moves between the active transport wheel and the auxiliary transport wheel, the transport motor drives the active wheel. Since the active wheel rotates, the active belt drives the driven wheel to rotate. At the same time, since the driven wheel rotates, the auxiliary belt can drive the remaining driven wheels to rotate. Through the rotation of the active wheel and the driven wheel, the active transport wheel and the auxiliary transport wheel can be rotated, which can drive the screw to continue moving. Then, the required feeding structure is docked with the outlet position of the transport rack, and the feeding operation during the screw processing can be completed. This reduces the time-consuming and laborious situation where during the screw processing, it is necessary to manually place the screws into the equipment one by one. It achieves the effect that multiple screws can be placed inside the supply box, and then the screws can be automatically fed through the cooperation of the placement rack and the connecting hydraulic device.

[0016] Through a plurality of card slots provided on the upper surface of the placement rack, screws with different diameters can be clamped and fixed. When the screws inside the supply box have different diameters but need to be transported to the same position, the docking hydraulic device is used to move the docking rack upward, and the fixing hydraulic device is used to move the placement rack upward, so that the docking rack jacks up a screw. After being jacked up, the screw is moved towards the transport rack by the connecting hydraulic device. After the screw moves between the main transport wheel and the auxiliary transport wheel, the transport motor drives the main wheel. Since the main wheel rotates, the main belt drives the driven wheel to rotate. At the same time, since the driven wheel rotates, the auxiliary belt can drive the remaining driven wheels to rotate. By the rotation of the main wheel and the driven wheel, the main transport wheel and the auxiliary transport wheel can be rotated, and the screw can be driven to continue moving. Then, the required feeding structure is docked with the outlet position of the transport rack, and the operation of transporting screws with different diameters can be completed. When the screws inside the supply box have different diameters and need to be transported separately, the docking hydraulic device is used to move the docking rack downward to reset, and the fixing hydraulic device is used to move the placement rack upward, so that the screw with the smallest diameter falls into the lowest card slot on the upper surface of the placement rack, the screw with a larger diameter falls into the card slot near the middle of the placement rack, and the screw with the largest diameter falls into the card slot near the upper part of the placement rack. Then, the fixing hydraulic device is used to move the placement rack upward to jack up all three screws with different diameters. After being jacked up, the screw is moved towards the transport rack by the connecting hydraulic device. After the screw moves between the main transport wheel and the auxiliary transport wheel, the transport motor drives the main wheel. Since the main wheel rotates, the main belt drives the driven wheel to rotate. At the same time, since the driven wheel rotates, the auxiliary belt can drive the remaining driven wheels to rotate. By the rotation of the main wheel and the driven wheel, the main transport wheel and the auxiliary transport wheel can be rotated, and the screw can be driven to continue moving. It should be noted that the gap between the main transport wheel and the auxiliary transport wheel closest to the upper part of the transport rack is the smallest, the gap between the main transport wheel and the auxiliary transport wheel near the middle of the transport rack is wider, and the gap between the main transport wheel and the auxiliary transport wheel closest to the lower part of the transport rack is the largest. The gap between the main transport wheel and the auxiliary transport wheel is used in combination with screws of different diameters, reducing the situation that during the screw processing and feeding, due to the different diameters of screws of different sizes and different processing methods, it is impossible to distinguish and feed screws of different diameters, resulting in difficulties in subsequent screw processing. It achieves the effect of being able to separate the feeding according to the different diameters of the screws, and at the same time, it can also feed the screws of different diameters uniformly, greatly enhancing the practicability of the screw processing and feeding device.

[0017] By placing the required transport screw inside the docking box, since the inside of the docking box is sloped, the screw can move along the slope towards the auxiliary plate. The auxiliary plate is moved upward by the auxiliary hydraulic device, so that the screw moves outward. After one screw is removed, the auxiliary plate is moved downward to reset by the auxiliary hydraulic device. The removed screw is intercepted by the positioning clamping plate. At the same time, the two positioning clamping plates are driven by the positioning double-headed motor, so that the two positioning clamping plates clamp the screw. The fixed fixture is moved downward by the moving hydraulic device, and then the fixture screw is driven by the fixture motor, so that the moving fixture moves parallelly, so that the fixed fixture and the moving fixture clamp and fix the screw. Then the fixed fixture and the screw are moved upward by the moving hydraulic device, and then the moving screw is driven by the moving motor to drive the moving screw, so that the moving slider drives the screw to move parallelly. When the screw passes through the first group of limit seats and the collision sensor but does not touch them, the moving screw continues to move until the surface of the screw touches the collision sensor. The moving fixture is driven by the fixture motor to drive the fixture screw, so that the moving fixture moves parallelly to reset, so that the screw falls into the corresponding storage box. Thus, the screws can be classified and placed according to their different lengths. After collection, by separating the classification bracket from the classification box and then taking out the storage box, the classified screws can be put into the supply box for feeding operation, reducing the situation that different types of screws have different lengths, and when feeding screws of different lengths, it is easy to have multiple screws of different lengths during the feeding process, and it is time-consuming and laborious for manual classification of screws of different lengths, and when screws of different lengths are fed simultaneously, since the processing processes of screws of different lengths are also different, it is easy to cause trouble to the subsequent processing process, achieving the effect of automatically classifying screws of different lengths in advance and then feeding the classified screws separately later.

[0018] In summary, the present invention has the advantages of being able to classify and feed or centrally feed screws of different diameters and lengths. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] As Figures 1-7 shown, embodiments of the present invention provide a multi-size adjustable screw machining feeding device and a usage method, including a bracket 1. A base 2 is fixedly connected to the upper surface of the bracket 1. A support frame 3 is fixedly connected to the upper surface of the base 2. A fixed hydraulic device 4 is fixedly connected to the upper surface of the bracket 1. A fixing plate 5 is fixedly connected to the upper surface of the fixed hydraulic device 4. A placement frame 6 is fixedly connected to the upper surface of the fixing plate 5. A docking hydraulic device 7 is fixedly connected to the inside of the placement frame 6. A docking frame 8 is fixedly connected to the upper surface of the docking hydraulic device 7. A supply box 9 is fixedly connected to the upper surface of the base 2. A supply chute is opened inside the supply box 9. The supply box 9 is slidably connected to the placement frame 6 through the supply chute. A connecting frame 10 is fixedly connected to the inside of the supply box 9. A connecting seat 11 is fixedly connected to the inside of the connecting frame 10. A connecting hydraulic device 12 is fixedly connected to the inside of the connecting seat 11. A transport frame 13 is fixedly connected to one side of the supply box 9. A transport seat 14 is fixedly connected to the inside of the transport frame 13. A transport motor 15 is fixedly connected to the inside of the transport seat 14. A driving wheel 16 is inserted into one end of the transport motor 15. A driving transport wheel 17 is fixedly connected to one end of the driving wheel 16. A driving belt 18 is sleeved on the surface of the driving wheel 16. A driven wheel 19 is rotatably connected to the inside of the transport frame 13. A groove is provided on the surface of the driven wheel 19. The driven wheel 19 is sleeved with the driving belt 18 through the groove. An auxiliary transport wheel 20 is fixedly connected to one end of the driven wheel 19. An auxiliary belt 21 is sleeved on the surface of the driven wheel 19.

[0028] By placing the screw inside the supply box 9, the fixing hydraulic device 4 is used to move the fixing plate 5 and the placement rack 6 upward. The screw inside the supply box 9 is lifted by the groove on the upper surface of the placement rack 6. After being lifted, the screw is moved towards the transport rack 13 by the connecting hydraulic device 12. After the screw moves between the driving transport wheel 17 and the auxiliary transport wheel 20, the driving motor 15 drives the driving wheel 16. Since the driving wheel 16 rotates, the driving belt 18 drives the driven wheel 19 to rotate. At the same time, since the driven wheel 19 rotates, the auxiliary belt 21 can drive the remaining driven wheels 19 to rotate. By the rotation of the driving wheel 16 and the driven wheel 19, the driving transport wheel 17 and the auxiliary transport wheel 20 can rotate, which can drive the screw to continue moving. Then, the required feeding structure is docked with the outlet position of the transport rack 13, and the feeding operation during the screw processing can be completed. This reduces the time-consuming and laborious situation where during the screw processing, it is necessary to manually place the screws into the equipment one by one. It achieves the effect that multiple screws can be placed inside the supply box 9, and then the screws can be automatically fed through the cooperation of the placement rack 6 and the connecting hydraulic device 12.

[0029] Through a plurality of clamping grooves provided on the upper surface of the placement rack 6, screws with different diameters can be clamped and fixed. When the screws in the supply box 9 have different diameters but need to be transported to the same position, the docking hydraulic device 7 is used to move the docking rack 8 upward, and the fixing hydraulic device 4 is used to move the placement rack 6 upward, so that the docking rack 8 jacks up a screw. After the screw is jacked up, the connecting hydraulic device 12 is used to move the screw in the direction of the transport rack 13. After the screw moves between the active transport wheel 17 and the auxiliary transport wheel 20, the transport motor 15 drives the active wheel 16. Since the active wheel 16 rotates, the active belt 18 drives the driven wheel 19 to rotate. At the same time, since the driven wheel 19 rotates, the auxiliary belt 21 can drive the remaining driven wheels 19 to rotate. Through the rotation of the active wheel 16 and the driven wheel 19, the active transport wheel 17 and the auxiliary transport wheel 20 can rotate, and the screw can be driven to continue to move. Then, the required feeding structure is docked with the outlet position of the transport rack 13, and the operation of transporting screws with different diameters can be completed. When the screws in the supply box 9 have different diameters and need to be transported separately, the docking hydraulic device 7 is used to move the docking rack 8 downward to reset, and the fixing hydraulic device 4 is used to move the placement rack 6 upward, so that the screw with the smallest diameter falls into the lowermost clamping groove on the upper surface of the placement rack 6, the screw with a larger diameter falls into the clamping groove near the middle of the placement rack 6, and the screw with the largest diameter falls into the clamping groove near the upper part of the placement rack 6. Then, the fixing hydraulic device 4 is used to move the placement rack 6 upward to jack up all three screws with different diameters. After the screws are jacked up, the connecting hydraulic device 12 is used to move the screws in the direction of the transport rack 13. After the screws move between the active transport wheel 17 and the auxiliary transport wheel 20, the transport motor 15 drives the active wheel 16. Since the active wheel 16 rotates, the active belt 18 drives the driven wheel 19 to rotate. At the same time, since the driven wheel 19 rotates, the auxiliary belt 21 can drive the remaining driven wheels 19 to rotate. Through the rotation of the active wheel 16 and the driven wheel 19, the active transport wheel 17 and the auxiliary transport wheel 20 can rotate, and the screw can be driven to continue to move. It should be noted that the gap between the active transport wheel 17 and the auxiliary transport wheel 20 at the uppermost part near the transport rack 13 is the smallest, the gap between the active transport wheel 17 and the auxiliary transport wheel 20 in the middle of the transport rack 13 is wider, and the gap between the active transport wheel 17 and the auxiliary transport wheel 20 at the lowermost part near the transport rack 13 is the largest. The gap between the active transport wheel 17 and the auxiliary transport wheel 20 is used in combination with screws of different diameters, reducing the situation that when processing and feeding screws, due to the different diameters of screws of different sizes and different processing methods, it is impossible to distinguish and feed screws of different diameters, resulting in difficulties in subsequent screw processing. It achieves the effect of being able to separate and feed screws according to their different diameters, and at the same time, it can also uniformly feed screws of different diameters, greatly enhancing the practicability of the screw processing and feeding device.

[0030] Such asFigure 3 and Figure 4 As shown in Figure 4 , in this embodiment, a supply rack 22 is fixedly connected inside the supply box 9, a supply double-headed motor 23 is fixedly connected inside the supply rack 22, an auxiliary rod 24 is fixedly connected inside the supply box 9, one end of the supply double-headed motor 23 is inserted with a supply lead screw 25, the surface of the supply lead screw 25 is threadedly penetrated with a limit plate 26, a limit hole is opened inside the limit plate 26, and the limit hole is slidably connected with the auxiliary rod 24.

[0031] By driving two supply lead screws 25 simultaneously by the supply double-headed motor 23, the two limit plates 26 move in opposite directions respectively until they are slightly longer than the required feeding screw length, and then the required feeding screw is placed inside the supply box 9. When feeding a screw with a shorter length, since the length inside the supply box 9 is longer while the required feeding screw length is shorter, multiple screws are placed side by side, which easily leads to the simultaneous transportation of multiple screws during the transportation of the screws, thus causing difficulties in subsequent processing. The effect of adjusting the distance between the two limit plates 26 according to the required feeding screw length is achieved, so that only one screw can be placed between the two limit plates 26, avoiding the situation of multiple screws being placed side by side.

[0033] By placing the required transport screw inside the docking box 27, since the inside of the docking box 27 is sloped, the screw can move along the slope towards the auxiliary plate 30. The auxiliary plate 30 is moved upward by the auxiliary hydraulic device 29, so that the screw moves outward. After one screw is removed, the auxiliary plate 30 is moved downward to reset by the auxiliary hydraulic device 29. The removed screw is intercepted by the positioning clamping plate 48. At the same time, the two positioning clamping plates 48 are driven by the positioning double-headed motor 46, so that the two positioning clamping plates 48 clamp the screw. The fixed clamp 41 is moved downward by the moving hydraulic device 40, and then the clamp screw 43 is driven by the clamp motor 42, so that the moving clamp 44 moves in parallel, so that the fixed clamp 41 and the moving clamp 44 clamp and fix the screw. Then the fixed clamp 41 and the screw are moved upward by the moving hydraulic device 40, and then the moving screw 38 is driven by the moving motor 37, so that the moving slider 39 drives the screw to move in parallel. When the screw passes through the first group of limit seats 34 and the collision sensor 35 but does not touch them, the moving screw continues to move until the surface of the screw touches the collision sensor 35. The clamp screw 43 is driven by the clamp motor 42, so that the moving clamp 44 moves in parallel to reset, so that the screw falls into the corresponding storage box 32. Thus, the screws can be classified and placed according to their different lengths. After collection, by separating the classification bracket 33 from the classification box 31 and then taking out the storage box 32, the classified screws can be put into the supply box 9 for feeding operation. This reduces the situation that different types of screws have different lengths, and when feeding screws of different lengths, it is easy to have multiple screws of different lengths during the feeding process, and it is time-consuming and laborious for manual classification of screws of different lengths, and when feeding screws of different lengths at the same time, since the processing processes of screws of different lengths are also different, it is easy to cause trouble to the subsequent processing process. It achieves the effect of automatically classifying screws of different lengths in advance and then feeding the classified screws separately later.

[0034] The electrical components appearing in this article are all electrically connected to the external main controller and 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0035] When the multi-size adjustable screw processing and feeding device and its use method are in use, it includes the following steps; Step 1: First, place the required transport screw inside the docking box 27. Multiple screws move along the slope towards the auxiliary plate 30. The auxiliary plate 30 is moved upward by the auxiliary hydraulic device 29, so that the screw moves outward. The removed screw is intercepted by the positioning clamping plate 48. The two positioning clamping plates 48 are driven by the positioning double-headed motor 46 at the same time, so that the two positioning clamping plates 48 clamp the screw; Step 2: Move the fixed fixture 41 downward by the moving hydraulic device 40, drive the fixture lead screw 43 by the fixture motor 42 to make the moving fixture 44 move parallelly, so that the fixed fixture 41 and the moving fixture 44 clamp and fix the screw. Then move the fixed fixture 41 and the screw upward by the moving hydraulic device 40, and then drive the moving lead screw 38 by the moving motor 37 to make the moving slider 39 drive the screw to move parallelly. When the screw passes through the first group of limit seats 34 and the collision sensor 35 but does not touch them, the screw continues to move until the surface of the screw touches the collision sensor 35. Drive the fixture lead screw 43 by the fixture motor 42 to make the moving fixture 44 move parallelly to reset, so that the screw falls into the corresponding storage box 32, and thus the screws can be classified, placed and collected according to their different lengths; Step 3: Drive the two supply lead screws 25 simultaneously by the supply double-head motor 23 to make the two limit plates 26 move in opposite directions until they are slightly longer than the required feeding screw length, and then put the required feeding screw into the supply box 9; Step 4: Put the screw into the supply box 9, move the fixed plate 5 and the placement rack 6 upward by the fixed hydraulic device 4, lift the screw inside the supply box 9 through the groove on the upper surface of the placement rack 6, and after lifting, move the screw toward the transport rack 13 by the connecting hydraulic device 12. The screw moves between the active transport wheel 17 and the auxiliary transport wheel 20; Step 5: Finally, drive the active wheel 16 by the transport motor 15. Since the active wheel 16 rotates, the active belt 18 drives the driven wheel 19 to rotate. At the same time, since the driven wheel 19 rotates, the auxiliary belt 21 can drive the remaining driven wheels 19 to rotate. By the rotation of the active wheel 16 and the driven wheel 19, the active transport wheel 17 and the auxiliary transport wheel 20 can be rotated, which can drive the screw to continue to move. Then dock the required feeding structure with the outlet position of the transport rack 13 to complete the feeding operation during the screw processing; Step 6: When the screws in the supply box 9 have different diameters but need to be transported to the same position, move the docking frame 8 upward by the docking hydraulic device 7, move the placement rack 6 upward by the fixed hydraulic device 4, make the docking frame 8 lift a screw, and after lifting, move the screw toward the transport rack 13 by the connecting hydraulic device 12. After the screw moves between the active transport wheel 17 and the auxiliary transport wheel 20, drive the active wheel 16 by the transport motor 15. Since the active wheel 16 rotates, the active belt 18 drives the driven wheel 19 to rotate. At the same time, since the driven wheel 19 rotates, the auxiliary belt 21 can drive the remaining driven wheels 19 to rotate. By the rotation of the active wheel 16 and the driven wheel 19, the active transport wheel 17 and the auxiliary transport wheel 20 can be rotated, which can drive the screw to continue to move. Then dock the required feeding structure with the outlet position of the transport rack 13 to complete the operation of transporting screws with different diameters; Step 7: When the screw diameters inside the supply box 9 are different and need to be transported separately, the docking hydraulic device 7 is used to move the docking frame 8 downward to the reset position, and the fixing hydraulic device 4 is used to move the placement rack 6 upward. As a result, the screw with the smallest diameter falls into the lowest card slot on the upper surface of the placement rack 6, the screw with a larger diameter falls into the card slot near the middle of the placement rack 6, and the screw with the largest diameter falls into the card slot near the upper part of the placement rack 6. Then, the fixing hydraulic device 4 is used to move the placement rack 6 upward to lift all three screws with different diameters. After being lifted, the connecting hydraulic device 12 is used to move the screws in the direction of the transport rack 13. After the screws move between the active transport wheel 17 and the auxiliary transport wheel 20, the transport motor 15 is used to drive the active wheel 16. Since the active wheel 16 rotates, the active belt 18 drives the driven wheel 19 to rotate. At the same time, since the driven wheel 19 rotates, the auxiliary belt 21 can drive the remaining driven wheels 19 to rotate. By the rotation of the active wheel 16 and the driven wheel 19, the active transport wheel 17 and the auxiliary transport wheel 20 can be rotated, which can drive the screws to continue moving, thus completing the separate transportation of screws with different diameters.

[0036] The technical solution provided by the present invention: First, place the required transportation screw into the inside of the docking box 27. Multiple screws move along the slope towards the auxiliary plate 30. The auxiliary plate 30 is moved upward by the auxiliary hydraulic device 29, so that the screws move outward. The removed screws are intercepted by the positioning clamping plates 48. The two positioning clamping plates 48 are driven simultaneously by the positioning double-headed motor 46, so that the two positioning clamping plates 48 clamp the screws. The fixed fixture 41 is moved downward by the moving hydraulic device 40. The fixture screw 43 is driven by the fixture motor 42, so that the moving fixture 44 moves parallelly, so that the fixed fixture 41 and the moving fixture 44 clamp and fix the screws. Then, the fixed fixture 41 and the screws are moved upward by the moving hydraulic device 40. Then, the moving screw 38 is driven by the moving motor 37, so that the moving slider 39 drives the screw to move parallelly. When the screw passes through the first group of limit seats 34 and the collision sensor 35 but does not touch them, the moving screw continues to move until the surface of the screw touches the collision sensor 35. The fixture screw 43 is driven by the fixture motor 42, so that the moving fixture 44 moves parallelly to reset, and the screw falls into the corresponding storage box 32 inside, so that the screws can be classified, placed and collected according to their different lengths. The two supply screws 25 are driven simultaneously by the supply double-headed motor 23, so that the two limit plates 26 move in opposite directions respectively until they are slightly longer than the required feeding screw length. Then, the required feeding screw is placed into the supply box 9. By placing the screw into the supply box 9, the fixing hydraulic device 4 moves the fixing plate 5 and the placement rack 6 upward. The screw inside the supply box 9 is lifted by the groove on the upper surface of the placement rack 6. After being lifted, the screw is moved towards the transport rack 13 by the connecting hydraulic device 12. The screw moves between the active transport wheel 17 and the auxiliary transport wheel 20. Finally, the transport motor 15 drives the active wheel 16. Since the active wheel 16 rotates, the active belt 18 drives the driven wheel 19 to rotate. At the same time, since the driven wheel 19 rotates, the auxiliary belt 21 can drive the remaining driven wheels 19 to rotate. By the rotation of the active wheel 16 and the driven wheel 19, the active transport wheel 17 and the auxiliary transport wheel 20 can rotate, and the screw can be driven to continue to move. Then, the required feeding structure is docked with the outlet position of the transport rack 13, and the feeding operation during the screw processing can be completed. When the screws inside the supply box 9 have different diameters but need to be transported to the same position, the docking hydraulic device 7 moves the docking frame 8 upward. The placement rack 6 is moved upward by the fixing hydraulic device 4, so that the docking frame 8 lifts a screw. After being lifted, the screw is moved towards the transport rack 13 by the connecting hydraulic device 12. After the screw moves between the active transport wheel 17 and the auxiliary transport wheel 20, the transport motor 15 drives the active wheel 16. Since the active wheel 16 rotates, the active belt 18 drives the driven wheel 19 to rotate. At the same time, since the driven wheel 19 rotates, the auxiliary belt 21 can drive the remaining driven wheels 19 to rotate. By the rotation of the active wheel 16 and the driven wheel 19, the active transport wheel 17 and the auxiliary transport wheel 20 can rotate,It can drive the screw to continue to move, and then dock the required feeding structure with the outlet position of the transport frame 13, and the operation of transporting screws with different diameters can be completed. When the diameters of the screws in the supply box 9 are different and they need to be transported separately, the docking hydraulic device 7 is used to move the docking frame 8 downward to reset, and the fixing hydraulic device 4 is used to move the placement frame 6 upward, so that the screw with the smallest diameter falls into the lowest card slot on the upper surface of the placement frame 6, the screw with a larger diameter falls into the card slot near the middle of the placement frame 6, and the screw with the largest diameter falls into the card slot near the upper part of the placement frame 6. Then, the fixing hydraulic device 4 is used to move the placement frame 6 upward to lift all three screws with different diameters. After lifting, the connecting hydraulic device 12 is used to move the screws in the direction of the transport frame 13. After the screws move between the active transport wheel 17 and the auxiliary transport wheel 20, the transport motor 15 is used to drive the active wheel 16. Since the active wheel 16 rotates, the active belt 18 drives the driven wheel 19 to rotate. At the same time, since the driven wheel 19 rotates, the auxiliary belt 21 can drive the remaining driven wheels 19 to rotate. By the rotation of the active wheel 16 and the driven wheel 19, the active transport wheel 17 and the auxiliary transport wheel 20 can be rotated, and the screw can be driven to continue to move, so as to complete the separate transportation of screws with different diameters.,
