Description

Technical Field

[0001] This invention relates to the field of metal wire conveying technology, and particularly to a belt conveyor device. Background Technology

[0002] Currently, to improve motor power and performance, drive motors used in new energy electric vehicles commonly use copper wire, especially rectangular copper wire, as the winding coil. Because copper wire is used as the winding coil, high precision is required during manufacturing. Currently, multiple pneumatic grippers on a conveyor line are typically used to clamp the copper wire for transport. During transport, the grippers need to be released, reset, and then clamped again, a complex process with low efficiency. Furthermore, the concentrated clamping force generated by the pneumatic grippers can easily cause deformation and damage to the copper wire, failing to meet the high-precision wire delivery requirements. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a belt-driven wire feeding device that conveys metal wires through left and right feeding mechanisms, achieving high conveying efficiency and meeting the high precision requirements of wire feeding.

[0004] The technical solution of this invention is: a belt-driven wire feeding device, comprising a machine base, a wire feeding mechanism at the upper end of the machine base, and a driving mechanism at the lower end of the machine base. The wire feeding mechanism includes a symmetrically arranged left wire feeding mechanism and a right wire feeding mechanism. The position of the right wire feeding mechanism is adjustable left and right relative to the machine base. The left and right wire feeding mechanisms each include a drive wheel and a pressure wheel. The drive wheel and the pressure wheel are connected by a belt drive. The belt of the left wire feeding mechanism and the belt of the right wire feeding mechanism cooperate with each other to feed wire. The driving mechanism includes a drive gear and a driven gear. The drive gear is circumferentially fixed on a drive shaft and driven to rotate by a motor. The driven gear is loosely fitted and axially... A main swing arm is fixed on a support shaft parallel to the drive shaft, with one end of the main swing arm extending and loosely fitted onto the support shaft, allowing the support shaft to rotate around the drive shaft. The drive mechanism also includes a left drive gear and a right drive gear. The left drive gear is circumferentially fixed to one end of a left main shaft, and the right drive gear is circumferentially fixed to one end of a right main shaft. The machine base is provided with left and right extending clearance holes, through which the other ends of the left and right main shafts pass and are circumferentially fixed to the drive wheels of the left and right wire feeding mechanisms, respectively. The left drive gear meshes with the power gear, and the right drive gear meshes with the driven gear.

[0005] The main swing arm is located below the drive gear and the driven gear, and the secondary swing arm is located above the drive gear and the driven gear. The two sides of the secondary swing arm are respectively sleeved on the drive shaft and the support shaft and are axially fixed to the drive shaft and the support shaft. The secondary swing arm is provided with an arc adjustment hole, the center of which coincides with the central axis of the drive shaft. The secondary swing arm is connected to the lower end of the machine tool by screws passing through the arc adjustment hole.

[0006] A tension spring is connected to the auxiliary swing arm. The tension spring is on the same side as the support shaft. The two ends of the tension spring are respectively connected and fixed to the auxiliary swing arm and the machine base, so as to enable the driven gear and the power gear to mesh without clearance.

[0007] The left and right wire feeding mechanisms each include an adjusting plate, which is movably and adjustablely connected to the upper end of the machine base. A first mounting shaft is fixedly mounted on the adjusting plate, and the clamping wheel is loosely fitted and axially fixed on the first mounting shaft. The line connecting the center of the clamping wheel and the center of the drive wheel is parallel to the wire feeding direction.

[0008] The adjustment plate is provided with multiple first strip-shaped holes extending left and right, and each first strip-shaped hole allows screws to pass through and connect to the machine base so that the adjustment plate can be moved left and right for adjustment.

[0009] The left and right wire feeding mechanisms each include a tensioning wheel, and the belt is sleeved on the drive wheel, the pressure wheel and the tensioning wheel.

[0010] The tensioning wheel is loosely fitted on a second mounting shaft, which is fixedly mounted on a tensioning adjustment block. The tensioning adjustment block has a second strip hole through which a screw passes to connect with an adjustment plate, allowing the tensioning adjustment block to move left and right relative to the adjustment plate for adjustment.

[0011] The upper end of the machine platform is provided with a first guide bracket and a second guide bracket for the wire. The first and second guide brackets are provided with guide grooves, which are respectively located on both sides of the wire feeding mechanism for the wire to be fed through and slide in the guide grooves for guidance.

[0012] Both the first guide bracket and the second guide bracket are provided with left and right extending strip grooves. The strip grooves allow screws to pass through and connect to the upper end of the machine base, so that the first and second guide brackets can be moved and adjusted left and right relative to the machine base.

[0013] The drive mechanism also includes two lubrication gears, one of which meshes with the left drive gear and the other with the right drive gear. The two lubrication gears are loosely fitted onto third mounting shafts, each of which is fixedly mounted on a mounting base. Each mounting base has a third slotted hole through which a screw passes to connect to the lower end of the machine tool, allowing the mounting base to move left and right relative to the machine tool for adjustment.

[0014] The above technical solution is adopted as follows: a wire feeding mechanism is provided at the upper end of the machine base, and a drive mechanism is provided at the lower end of the machine base. The wire feeding mechanism includes a symmetrically arranged left wire feeding mechanism and a right wire feeding mechanism. The position of the right wire feeding mechanism is adjustable left and right relative to the machine base. The left and right wire feeding mechanisms each include a drive wheel and a pressure wheel. The drive wheel and the pressure wheel are connected by a belt drive. The belt of the left wire feeding mechanism and the belt of the right wire feeding mechanism cooperate with each other to feed the wire. The drive mechanism includes a drive gear and a driven gear. The drive gear is circumferentially fixed on a drive shaft and driven to rotate by a motor. The driven gear is loosely fitted and axially fixed to a drive shaft. On a parallel support shaft, a main swing arm is loosely fitted and axially fixed on the drive shaft. One end of the main swing arm extends and is loosely fitted on the support shaft, allowing the support shaft to rotate around the drive shaft. The drive mechanism also includes a left drive gear and a right drive gear. The left drive gear is circumferentially fixed to one end of a left main shaft, and the right drive gear is circumferentially fixed to one end of a right main shaft. The machine base is provided with left and right extending clearance holes. The other ends of the left and right main shafts pass through the clearance holes and are circumferentially fixed to the drive wheels of the left and right wire feeding mechanisms, respectively. The left drive gear meshes with the power gear, and the right drive gear meshes with the driven gear.

[0015] In this belt-driven wire feeding device, a motor drives a drive shaft to rotate, which in turn rotates a power gear. This power gear then drives a driven gear and a left drive gear, which in turn drives a right drive gear. Finally, the left drive gear, via the left main shaft, drives the left drive wheel, thus moving the belt of the left wire feeding mechanism. Similarly, the right drive gear, via the right main shaft, drives the right drive wheel, thus moving the belt of the right wire feeding mechanism. The two belts work in sync, transporting the wire between them forward. The wire feeding is uninterrupted and highly efficient, improving production efficiency. Furthermore, the belts provide cushioning, resulting in better contact and a higher degree of fit between the belts and the wire, preventing deformation and damage, and meeting the high-precision requirements of wire feeding. In addition, the position of the right wire feeding mechanism is adjustable left and right relative to the machine. Before feeding, the position of the right wire feeding mechanism is adjusted according to the wire size to ensure the spacing between the left and right belts is suitable for wire feeding. During adjustment, the right drive wheel, right main shaft, and right drive gear will all move together to the left or right. Because the driven gear of the main swing arm can revolve around the drive gear, during the movement of the right drive gear, the driven gear can adaptively revolve around the drive gear and remain close to the right drive gear, always meshing with it. After adjustment, the position of the support shaft can be fixed. This adjustment allows the device to be used for conveying wires of different sizes, expanding its applicability, and also simplifies adjustments during production changes.

[0016] The main swing arm is located below the drive gear and driven gear, and a secondary swing arm is located above the drive gear and driven gear. The two sides of the secondary swing arm are respectively sleeved on the drive shaft and support shaft, and are axially fixed to the drive shaft and support shaft. The secondary swing arm has an arc-shaped adjustment hole, the center of which coincides with the central axis of the drive shaft. The secondary swing arm is connected to the lower end of the machine tool by screws passing through the arc-shaped adjustment hole. The secondary swing arm also allows the driven gear to revolve around the drive gear, and also serves to fix the position of the driven gear. Before adjustment, loosen the screw in the arc-shaped adjustment hole. During adjustment, as the driven gear adaptively rotates around the drive gear, the support shaft and the secondary swing arm will also rotate around the drive gear. After rotation to the correct position, tighten the screw in the arc-shaped adjustment hole to fix the position of the driven gear, making the drive mechanism more stable.

[0017] A tension spring is connected to the auxiliary swing arm, and the tension spring is on the same side as the support shaft. The two ends of the tension spring are respectively connected and fixed to the auxiliary swing arm and the machine base, which is used to ensure that the driven gear and the right driving gear mesh without clearance. After loosening the screw in the arc-shaped adjustment hole, the tension of the tension spring can keep the driven gear close to the right driving gear at all times, and ensure that there is no clearance between them.

[0018] The left and right wire feeding mechanisms each include an adjusting plate, which is movably and adjustablely connected to the upper end of the machine base. A first mounting shaft is fixedly mounted on the adjusting plate, and the pressure wheel is loosely fitted and axially fixed on the first mounting shaft. The line connecting the center of the pressure wheel and the center of the drive wheel is parallel to the wire feeding direction. The adjusting plate makes the wire feeding mechanisms more integrated and easier to move and adjust. The adjusting plate has multiple left-right extending first strip holes, each for screws to pass through and connect to the machine base, allowing the adjusting plate to move left and right for adjustment. Before adjustment, loosen the screws in the first strip holes. During adjustment, move the adjusting plate left or right until it is in place, then tighten the screws in the first strip holes to fix the position of the adjusting plate.

[0019] The left and right wire feeding mechanisms each include a tensioning pulley, and the belt is fitted onto the drive wheel, the pressure wheel, and the tensioning pulley. The tensioning pulleys allow for adjustable belt tension in each wire feeding mechanism, preventing belt slippage and improving conveying stability.

[0020] The tensioning pulley is loosely fitted onto a second mounting shaft, which is fixedly mounted on a tensioning adjustment block. The tensioning adjustment block has a second slotted hole through which a screw passes to connect with an adjusting plate, allowing the tensioning adjustment block to move left and right relative to the adjusting plate for adjustment. Adjusting the belt tension using the tensioning pulley is also simple: before adjustment, loosen the screw in the second slotted hole, then move the tensioning adjustment block left and right until the tensioning pulley is in position, and finally tighten the screw in the second slotted hole.

[0021] The upper part of the machine platform is provided with a first guide bracket and a second guide bracket for the wire. The first and second guide brackets are provided with guide grooves, which are respectively located on both sides of the wire feeding mechanism to guide the wire through which it slides. The first guide bracket and the second guide bracket form a guide for the wire feeding, so that the wire enters or exits the wire feeding mechanism in a direction parallel to the line connecting the center of the pressure wheel and the center of the drive wheel, thereby improving the wire feeding accuracy.

[0022] Both the first and second guide supports are provided with left-right extending slots. These slots allow screws to pass through and connect to the upper end of the machine base, enabling the first and second guide supports to move and adjust left and right relative to the machine base. The left and right adjustment of the first and second guide supports further facilitates the alignment of the conveyed wire with the center position between the two belts, resulting in higher wire conveying accuracy.

[0023] The drive mechanism also includes two lubrication gears, one of which meshes with the left drive gear and the other with the right drive gear. Each lubrication gear is loosely fitted onto a third mounting shaft, which is fixedly mounted on a mounting base. Each mounting base has a third slotted hole through which a screw passes to connect to the lower end of the machine tool, allowing the mounting base to move left and right relative to the machine tool. Lubrication of the lubrication gears reduces wear on the drive mechanism, and the position of the lubrication gears can be adjusted according to the movement of the right drive gear. Before adjustment, loosen the screw in the third slotted hole. After the right drive gear is adjusted to its position, maintain engagement between the right lubrication gear and the right drive gear, then tighten the screw in the third slotted hole.

[0024] The belt-driven wire feeding device of this invention enables uninterrupted wire feeding with high efficiency, thus improving production efficiency. The belt provides cushioning, resulting in better contact and a higher degree of fit between the belt and the wire, preventing wire deformation and damage, and meeting the high-precision requirements of wire feeding. Furthermore, the position of the right wire feeding mechanism relative to the machine base is adjustable left and right. During adjustment, the driven gear adaptively revolves around the driving gear and remains close to and meshes with the right driving gear. This adjustment allows the device to be used for feeding wires of different sizes, expanding its applicability, and simplifying adjustments during production changes.

Detailed Implementation

[0037] See Figures 1 to 10A belt-driven wire feeding device includes a machine base 1, which may be made of metal. A wire feeding mechanism is provided at the upper end of the machine base 1, and a drive mechanism is provided at the lower end of the machine base 1. The wire feeding mechanism includes a symmetrically arranged left wire feeding mechanism and a right wire feeding mechanism, the position of which is adjustable left and right relative to the machine base 1. The left and right wire feeding mechanisms each include a drive wheel 9 and a pressure wheel 5, which are connected by a belt 6. The belt 6 of the left and right wire feeding mechanisms cooperates to feed wire 3. In this embodiment, the wire 3 being fed can be a metal wire, such as copper wire, and specifically, a rectangular copper wire. The left and right wire feeding mechanisms each include an adjusting plate 2, which is movably and adjustablely connected to the upper end of the machine base 1. A first mounting shaft is fixedly mounted on the adjusting plate 2, and the pressure wheel 5 is loosely fitted and axially fixed on the first mounting shaft. The line connecting the center of the pressure wheel 5 and the center of the drive wheel 9 is parallel to the feeding direction of the wire 3. The adjusting plate 2 integrates the various wire feeding mechanisms, making them easier to move and adjust. The adjusting plate 2 has multiple left-right extending first strip holes 2-1, through which screws pass to connect with the machine base 1, allowing the adjusting plate 2 to move left and right for adjustment. Before adjustment, loosen the screws in the first strip holes 2-1. During adjustment, move the adjusting plate 2 left or right until it is in place, then tighten the screws in the first strip holes 2-1 to fix the position of the adjusting plate 2.

[0038] The left and right wire feeding mechanisms of the device each include a tensioning wheel 7. The belt 6 is sleeved on the drive wheel 9, the pressure wheel 5, and the tensioning wheel 7. The tensioning wheel 7 makes the tension of the belt 6 of each wire feeding mechanism adjustable, preventing the belt 6 from slack and slipping, and improving the stability of the conveying. The tensioning wheel 7 is loosely fitted and axially fixed on a second mounting shaft. The second mounting shaft is fixedly mounted on a tensioning adjustment block 8. The tensioning adjustment block 8 has a second slotted hole 9-1, through which a screw passes to connect with the adjusting plate 2, allowing the tensioning adjustment block 8 to move left and right relative to the adjusting plate 2 for adjustment. The tension adjustment of the belt 6 by the tensioning wheel 7 is also simple: before adjustment, loosen the screw in the second slotted hole 9-1, then move the tensioning adjustment block 8 left and right to bring the tensioning wheel 7 into position, and then tighten the screw in the second slotted hole 9-1.

[0039] The drive mechanism of the device includes a drive gear 19 and a driven gear 17. The drive gear 19 is circumferentially and axially fixed on a drive shaft 16, which is fixedly connected to the motor shaft 11 of the motor 11, causing the motor 11 to drive the drive gear 19 to rotate. The driven gear 17 is loosely fitted and axially fixed on a support shaft parallel to the drive shaft 16. A main swing arm 14 is loosely fitted and axially fixed on the drive shaft 16, and the main swing arm 14 has a hole for the drive shaft 16 to pass through. One end of the main swing arm 14 extends and is loosely fitted on the support shaft, allowing the support shaft to rotate around the drive shaft 16. The main swing arm 14 also has a hole for the support shaft to pass through. The drive mechanism also includes a left drive gear 15 and a right drive gear 13. The left drive gear 15 is circumferentially and axially fixed on one end of a left main shaft 23, and the right drive gear 13 is circumferentially and axially fixed on one end of a right main shaft 22. The machine base 1 is provided with left and right extending clearance holes 1-1. The other ends of the left and right main shafts pass through the clearance holes 1-1 and are circumferentially fixed to the drive wheels 9 of the left and right wire feeding mechanisms, respectively. The clearance holes 1-1 provide sufficient space for the adjustment of the right wire feeding mechanism. That is, the two ends of the left main shaft 23 extend out of the upper and lower end faces of the machine base 1, respectively, and the drive wheel 9 of the left wire feeding mechanism and the left drive gear 15 are fixedly installed thereon; the two ends of the right main shaft 22 extend out of the upper and lower end faces of the machine base 1, respectively, and the drive wheel 9 of the right wire feeding mechanism and the right drive gear 13 are fixedly installed thereon. The left drive gear 15 meshes with the power gear 19, and the right drive gear 13 meshes with the driven gear 17.

[0040] The main swing arm 14 of the device is located below the drive gear 19 and the driven gear 17, and a secondary swing arm 20 is located above the drive gear 19 and the driven gear 17. The two sides of the secondary swing arm 20 are respectively sleeved on the drive shaft 16 and the support shaft, and are axially fixed to the drive shaft 16 and the support shaft. The secondary swing arm 20 is provided with an arc-shaped adjustment hole 20-1, the center of which coincides with the central axis of the drive shaft 16. The secondary swing arm 20 is connected to the lower end of the machine base 1 by screws passing through the arc-shaped adjustment hole 20-1. The secondary swing arm 20 can also cause the driven gear 17 to revolve around the drive gear 19, and also serves to fix the position of the driven gear 17. Before adjustment, loosen the screw in the arc-shaped adjustment hole 20-1. During adjustment, as the driven gear 17 rotates adaptively around the drive gear 19, the support shaft and the secondary swing arm 20 will also rotate around the drive gear 19. After rotation to the correct position, tighten the screw in the arc-shaped adjustment hole 20-1 to fix the position of the driven gear 17, making the drive mechanism more stable. A tension spring 18 is connected to the secondary swing arm 20. The tension spring 18 is on the same side as the support shaft, and its two ends are respectively connected and fixed to the secondary swing arm 20 and the machine base 1, which is used to ensure that the driven gear 17 and the right drive gear 13 mesh without clearance. After loosening the screw in the arc-shaped adjustment hole 20-1, the tension of the tension spring 18 ensures that the driven gear 17 is always close to the right drive gear 13, and meshes with the right drive gear 13 without clearance.

[0041] In this embodiment, a first guide bracket 4 and a second guide bracket 10 for the wire 3 are provided on the upper end of the machine base 1. Guide grooves are provided on the first and second guide brackets, which are respectively located on both sides of the wire feeding mechanism for the wire 3 to pass through and slide in the guide grooves. The first guide bracket 4 and the second guide bracket 10 form a guide for the wire 3, ensuring that the wire 3 enters or exits the wire feeding mechanism parallel to the line connecting the center of the pressure wheel 5 and the center of the drive wheel 9, thus improving the feeding accuracy of the wire 3. Both the first guide bracket 4 and the second guide bracket 10 are provided with left-right extending strip grooves 24. Screws pass through these strip grooves 24 to connect to the upper end of the machine base 1, allowing the first and second guide brackets to move left and right relative to the machine base 1 for adjustment. The shapes of the strip grooves 24 on the first guide bracket 4 and the second guide bracket 10 can be the same or different. The first guide bracket 4 and the second guide bracket 10 can also be adjusted left and right, which is more conducive to adjusting the fed wire 3 to the center position between the two belts 6, resulting in higher feeding accuracy of the wire 3. The drive mechanism also includes two lubrication gears 12, one of which meshes with the left drive gear 15, and the other meshes with the right drive gear 13. The two lubrication gears 12 are loosely fitted and axially fixed on third mounting shafts, each of which is fixedly mounted on a mounting base 21. Each mounting base 21 has a third slotted hole through which a screw passes to connect to the lower end of the machine base 1, allowing the mounting base 21 to move left and right relative to the machine base 1 for adjustment. Lubrication of the lubrication gears 12 reduces wear on the drive mechanism, and the lubrication gears 12 can also be adjusted in position according to the movement of the right drive gear 13. Before adjustment, loosen the screw in the third slotted hole. After the right drive gear 13 is adjusted to its position, maintain the engagement between the right lubrication gear 12 and the right drive gear 13, then tighten the screw in the third slotted hole.

[0042] In the wire feeding device of this invention, the motor 11 drives the drive shaft 16 to rotate during feeding, thereby causing the power gear 19 to rotate. The power gear 19 drives the driven gear 17 and the left drive gear 15 to rotate, and the rotating driven gear 17 drives the right drive gear 13 to rotate. Finally, the left drive gear 15 drives the left drive wheel 9 to rotate through the left main shaft 23, realizing the movement of the belt 6 of the left wire feeding mechanism. The right drive gear 13 drives the right drive wheel 9 to rotate through the right main shaft 22, realizing the movement of the belt 6 of the right wire feeding mechanism. The two belts 6 cooperate and move synchronously to feed the wire 3 located between the two belts 6 forward. The feeding of the wire 3 is uninterrupted, the feeding efficiency is high, and the production efficiency is improved. Moreover, the belt 6 has a buffering effect, the contact between the belt 6 and the wire 3 is better, and the fit between them is also higher, which can prevent the wire 3 from being deformed and damaged, thus meeting the high precision requirements of wire feeding.

[0043] Furthermore, the position of the right wire feeding mechanism in this device is adjustable left and right relative to the machine base 1. Before feeding, the position of the right wire feeding mechanism is adjusted according to the size of the wire 3 so that the spacing between the left and right belts 6 is suitable for feeding the wire 3. During adjustment, the right drive wheel 9, the right main shaft 22, and the right drive gear 13 will all move to the left or right together. Because the driven gear 17 of the main swing arm 14 can revolve around the drive gear 19, the driven gear 17 can adaptively revolve around the drive gear 19 during the movement of the right drive gear 13 and always mesh with the right drive gear 13. After adjustment, the position of the support shaft can be fixed. By adjusting, this device can be used to feed wires 3 of different sizes, expanding the applicability of the device, and the adjustment of the device is also simple during production changeover.
