Description

Technical Field

[0001] This application relates to the field of feeding devices, and in particular to a feeding device for a motor gear shaft. Background Technology

[0002] In the process of motor manufacturing, the gear shaft, as a key transmission component, needs to be accurately and efficiently assembled into the motor housing.

[0003] To improve the overall automation level, current production lines typically place the gear shaft in a vibratory feeder. The vibratory feeder is connected to the assembly structure via a feed channel, and the assembly structure is used to install the gear shaft into the housing.

[0004] To improve the service life of gear shafts, an oil film is usually present on the surface of the gear shaft. During the continuous feeding process of the gear shaft vibrating by the vibratory feeder, the gear shaft collides continuously with the vibratory feeder, which can easily generate some metal debris, causing contamination of the gear shaft. This debris can also adhere to the gear shaft, resulting in poor feeding efficiency of the feeding device, which needs to be improved. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a motor gear shaft feeding device.

[0006] This application provides a motor gear shaft feeding device, which adopts the following technical solution: A motor gear shaft feeding device includes a feeding box, a material channel on the feeding box, a guide plate inclinedly arranged on the material channel, a feeding plate slidably connected to the feeding box in the vertical direction, the feeding plate being arranged on the side of the guide plate away from the material channel, a feeding inclined surface that cooperates with the guide plate on the feeding plate, and a vibration motor on the feeding box.

[0007] By adopting the above technical solution, workers place the gear shaft into the feeding box, and under the action of gravity, the gear shaft moves to the feeding plate. The feeding plate rises, driving part of the gear shaft to move. When the feeding ramp on the feeding plate is aligned with the guide ramp, the gear shaft falls onto the material channel under its own weight, completing the feeding of the gear shaft. At this time, the feeding plate shortens the feeding time of the gear shaft and reduces the possibility of damage due to prolonged vibration, thereby improving the feeding efficiency of the feeding device.

[0008] Preferably, the feeding box is equipped with an infrared sensor, which is positioned opposite to the material channel. The feeding box is also equipped with an air pipe, which is positioned opposite to the material channel. The material channel is equipped with a return plate, with the end of the return plate furthest from the material channel inclined downwards compared to the end closer to the material channel.

[0009] By adopting the above technical solution, the infrared sensor detects the feeding direction of the gear shaft. When the feeding direction of the gear shaft deviates from the set direction, air is released from the air pipe, blowing the non-compliant gearbox to the return plate. The return plate then feeds the gear shaft back into the feeding box so that the feeding plate can feed the gear shaft again in the future.

[0010] Preferably, the feeding box is provided with a height-fixing plate, the lowest height of which is lower than the highest height of the feeding plate, and the highest height of which is higher than the highest height of the feeding plate.

[0011] By adopting the above technical solution, the height limit plate limits the stacking height of gear shafts in the feeding box, reducing the possibility of excessive gear shafts overflowing directly onto the guide plate or material channel, and improving the stability of the feeding device during feeding.

[0012] Preferably, a movable plate is slidably connected to the guide plate, the movable plate is provided with a plurality of partitions, the guide plate is provided with a plurality of clearance holes, each partition corresponds to a clearance hole, the partition is slidably connected in the clearance hole at the corresponding position, and the feeding plate is provided with a control component for controlling the movement of the movable plate.

[0013] By adopting the above technical solution, during the process of the feeding plate moving the gear shaft to the guide plate, the control component is activated and drives the moving plate to move. The moving plate controls each partition to extend from the corresponding clearance hole. At this time, the partition provides further guidance for the gear shaft, improving the uniformity of the gear shaft moving onto the material channel.

[0014] Preferably, the control assembly includes a control board, a control rod, and a cam. The feeding box is provided with a guide frame, the control board is slidably connected to the guide frame, one end of the control rod is rotatably connected to the control board, and the other end is rotatably connected to the cam. The cam is rotatably connected to the feeding box, the control rod is eccentrically mounted on the cam, the feeding plate is provided with a connecting plate, the connecting plate is provided with a connecting rod, and the connecting rod is connected to the side of the control board opposite to the control rod.

[0015] By adopting the above technical solution, the feeding plate moves, driving the connecting plate to move, which in turn drives the connecting rod to move. The connecting rod drives the control plate to move along the guide frame, and during the movement of the control plate, it drives the control rod to rotate. The control rod then drives the cam to rotate, and the cam abuts against the moving plate, driving the moving plate to move. This achieves the function of automatic lifting of the partition, so that the gear shaft can move more evenly onto the material channel.

[0016] Preferably, the movable plate is provided with a first spring, and the end of the first spring away from the movable plate is connected to the guide plate.

[0017] By employing the above technical solution, the first spring is compressed during the movement of the moving plate. During the resetting process of the feeding plate, the cam continues to rotate. At this time, under the action of the rebound force of the first spring, the moving plate and each partition automatically reset, so that the partitions can continue to separate the gear shaft subsequently.

[0018] Preferably, the feeding box is provided with a support plate, a gathering plate is slidably connected to the support plate, and two opposing baffles are provided on the gathering plate. The gathering plate is disposed in the feeding box, and the two opposing baffles are slidably connected to the feeding box. The feeding box is provided with a drive assembly for controlling the movement of the gathering plate. When the feeding plate is reset, the drive assembly controls the gathering plate to move toward the guide plate so as to move the gear shaft to the feeding plate.

[0019] By adopting the above technical solution, after the loading plate is loaded, the drive assembly starts and moves the gathering plate and two baffles. At this time, the gathering plate moves the gear shaft returning from the return plate to the loading plate, so that the loading plate can stably transfer the gear shaft to the guide plate, realizing the automatic loading function of the gear shaft. At the same time, the baffles block the gear shaft, reducing the path of the gear shaft to the gathering plate, making it less likely for the gathering plate to squeeze the gear shaft and cause damage to the gear shaft.

[0020] Preferably, the driving assembly includes a driving block, a first guide wheel, a second guide wheel, and a pull rope. A driving hole is provided on the support plate. The driving block is slidably connected in the support plate and is connected to a baffle. The first guide wheel is rotatably connected to the support plate, and the second guide wheel is rotatably connected to the feeding box. One end of the pull rope is connected to the driving block, and the other end passes around the first guide wheel and the second guide wheel in sequence before being connected to the feeding plate.

[0021] By adopting the above technical solution, during the resetting process of the feeding plate, the feeding plate drives the pull rope to move. Under the guidance of the first and second guide wheels, the pull rope can pull the drive block. The drive block then drives the baffle and the convergence plate to move, and the convergence plate can move the gear shaft to the feeding plate.

[0022] Preferably, a second spring is provided in the driving hole, with one end of the second spring connected to the driving block and the other end connected to the inner wall of the driving hole.

[0023] By adopting the above technical solution, the second spring is compressed during the movement of the drive block. During the repositioning of the feeding plate, the drive block automatically resets under the rebound force of the second spring, and the drive block controls the baffle and the convergence plate to reset automatically. At the same time, the drive block controls the pull rope to reset, so that the pull rope is straightened again, thereby realizing the function of automatic reset of the drive assembly.

[0024] In summary, this application includes at least one of the following beneficial technical effects: By setting up a feeding plate instead of a vibratory feeder, the feeding distance of the gear shaft is shortened, improving the feeding efficiency of the feeding device. On the other hand, it reduces the possibility of damage to the gear shaft due to long-term vibration, thus improving the feeding effect of the feeding device. By setting up partitions, the gear shafts on the guide plate are separated, which improves the uniformity of gear shaft feeding and makes the material channel convey the gear shafts more stably. By setting up a convergence plate, the convergence plate gathers the gear shafts returning from the return plate, so that the gear shafts can be moved more accurately to the feeding plate, which facilitates the subsequent feeding of the gear shafts by the feeding plate.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. Example

[0028] Embodiment 1 of this application discloses a motor gear shaft feeding device. (Refer to...) Figure 1A gear shaft feeding device includes a feeding box 1, a feeding channel 11, and a vibrating motor 12. A guide plate 13 is inclinedly arranged on the feeding channel 11, with the end of the guide plate 13 furthest from the feeding channel 11 inclined upwards compared to the end closer to the feeding channel 11. A feeding plate 2 is slidably connected to the feeding box 1 in a vertical direction. The feeding plate 2 is driven by an external linear drive mechanism, and a feeding inclined surface 21 that cooperates with the guide plate 13 is provided on the feeding plate 2. When feeding a gear shaft, the feeding plate 2 moves, causing the gear shaft to move. When the feeding inclined surface 21 is opposite to the guide plate 13, the gear shaft moves to the feeding channel 11 under its own gravity, and the vibrating motor 12 is activated, causing the gear shaft to move along the feeding channel 11. At this time, under the action of the feeding plate 2, on the one hand, the feeding distance of the gear shaft is shortened, and the feeding efficiency of the feeding device is improved. On the other hand, the gear shaft is not easily damaged by long-term vibration, thereby improving the feeding effect of the feeding device.

[0029] Reference Figure 1 In order to improve the accuracy of gear shaft conveying, an infrared sensor 14 is installed on the feeding box 1. The infrared sensor 14 is set opposite to the material channel 11 and is used to monitor the orientation of the gear shaft.

[0030] Furthermore, an air pipe 15 is provided on the feeding box 1, and an air source is connected to the air pipe 15. The air pipe 15 is arranged opposite to the material channel 11, and the axis of the air pipe 15 is perpendicular to the axis of the infrared sensor 14. A return plate 16 is provided on the material channel 11, and the end of the return plate 16 away from the material channel 11 is inclined downward compared to the end closer to the material channel 11.

[0031] As the gear shaft moves along the feed channel 11, the infrared sensor 14 monitors the actual orientation of the gear shaft. When the orientation of the gear shaft deviates from the set direction, the air pipe 15 sprays air, causing the non-compliant gear shaft to detach from the feed channel 11. Under its own gravity, the gear shaft re-enters the feed box 1 from the return plate 16, so that the feed plate can subsequently re-feed the gear shaft.

[0032] Reference Figure 1 To improve the stability of the feeding plate 2 during feeding, a height-fixing plate 17 is fixed on the feeding box 1. The minimum height of the height-fixing plate 17 is lower than the maximum height of the feeding plate 2, and the maximum height of the height-fixing plate 17 is higher than the maximum height of the feeding plate 2. When there are many gear shafts in the feeding box 1, the height-fixing plate 17 blocks the gear shafts, reducing the possibility that the gear shafts will bypass the infrared sensor 14 and move directly onto the material channel 11, thereby improving the accuracy of the feeding device during feeding.

[0033] The implementation principle of Embodiment 1 of this application is as follows: When it is necessary to feed the gear shaft, the feeding plate 2 is activated and drives the gear shaft in the feeding box 1 to move. When the feeding inclined surface 21 of the feeding plate 2 is opposite to the guide plate 13, the gear shaft moves from the guide plate 13 to the material channel 11 under its own gravity. The vibration motor 12 is activated and drives the gear shaft to move, so as to realize the function of automatic feeding. At this time, under the action of the feeding plate 2, on the one hand, the feeding distance of the gear shaft is shortened, and the feeding efficiency of the feeding device is improved. On the other hand, due to the shortened distance, the gear shaft is less likely to be damaged by long-term vibration, reducing the possibility of debris affecting the performance of the gear shaft, thereby improving the feeding effect of the feeding device. Example

[0034] Reference Figure 2 and Figure 3 The difference from Embodiment 1 of this application is that, in order to improve the stability of the feeding plate 2 during feeding, a movable plate 3 is slidably connected to the guide plate 13, and a plurality of partitions 31 are provided on the movable plate 3. A plurality of clearance holes are provided on the guide plate 13, and each partition 31 corresponds to a clearance hole, and the partition 31 is slidably connected to the clearance hole at the corresponding position.

[0035] The feeding plate 2 is equipped with a control component 4 for controlling the movement of the moving plate 3. The control component 4 includes a control plate 41, a control rod 42, and a cam 43. A guide frame 18 is fixed on the feeding box 1, and the control plate 41 is slidably connected in the guide frame 18. A connecting plate 22 is provided on the feeding plate 2, and a connecting rod 23 is provided on the connecting plate 22, which is connected to the control plate 41. One end of the control rod 42 is rotatably connected to the cam 43, and the other end is rotatably connected to the end of the control plate 41 away from the connecting rod 23. The cam 43 is rotatably connected to the feeding box 1, and the control rod 42 is eccentrically mounted on the cam 43.

[0036] During the movement of the gear shaft on the feeding plate 2, the connecting plate 22 moves, which in turn moves the connecting rod 23. The connecting rod 23 moves the control plate 41 along the guide frame 18, and during the movement of the control plate 41, it rotates the control rod 42. The control rod 42 then rotates the cam 43, which abuts against the moving plate 3 and moves the moving plate 3, thus realizing the function of automatic lifting of the partition 31. At this time, each partition 31 separates the guide plate 13 so that the gear shaft moves more evenly onto the material channel 11.

[0037] Reference Figure 3 In order to facilitate the control of the resetting of the moving plate 3 and each partition 31, a first spring 5 is provided on the moving plate 3, and the end of the first spring 5 away from the moving plate 3 is connected to the guide plate 13.

[0038] During the movement of the moving plate 3, the first spring 5 is compressed. During the reset of the feeding plate 2, the cam 43 continues to rotate. At this time, under the action of the rebound force of the first spring 5, the moving plate 3 and each partition 31 automatically reset, so that the partition 31 can continue to separate the gear shaft.

[0039] Reference Figure 4 and Figure 5 As the feeding plate 2 continuously feeds materials, the number of gear shafts in the feeding box 1 gradually decreases. To improve the accuracy of feeding by the feeding plate 2, a support plate 6 is provided on the feeding box 1. A gathering plate 7 is slidably connected to the support plate 6 and extends into the feeding box 1. Two opposing baffles 71 are connected to the gathering plate 7, and the baffles 71 are slidably connected to the support plate 6 and to the feeding box 1.

[0040] To facilitate control of the gathering plate 7, a drive assembly 8 for controlling the movement of the gathering plate 7 is provided on the feeding box 1. When the feeding plate 2 is reset, the drive assembly 8 controls the direction of the guide plate 13 of the groove of the gathering plate 7 to move the gear shaft to the feeding plate 2.

[0041] Reference Figure 4 and Figure 5 The drive assembly 8 includes a drive block 81, a first guide wheel 82, a second guide wheel 83, and a pull rope 84. A drive hole 61 is provided on the support plate 6, and the drive block 81 is slidably connected in the support plate 6. The drive block 81 is connected to the baffle 71. The first guide wheel 82 is rotatably connected to the support plate 6, and the second guide wheel 83 is rotatably connected to the feeding box 1. One end of the pull rope 84 is connected to the drive block 81, and the other end passes sequentially around the first guide wheel 82 and the second guide wheel 83 before connecting to the feeding plate 2.

[0042] During the resetting process of the feeding plate 2, the feeding plate 2 drives the pull rope 84 to move. Under the guidance of the first guide wheel 82 and the second guide wheel 83, the pull rope 84 can pull the drive block 81. The drive block 81 then drives the baffle 71 and the gathering plate 7 to move, and the gathering plate 7 can move the gear shaft to the feeding plate 2. At the same time, the arrangement of the first guide wheel 82 and the second guide wheel 83 makes it difficult for the pull rope 84 to directly contact the feeding box 1 during the movement, reducing the possibility of damage to the pull rope 84. At the same time, the baffle 71 blocks the gear shaft, reducing the path of the gear shaft to the gathering plate 7, making it less likely for the gathering plate 7 to squeeze the gear shaft and cause damage to the gear shaft.

[0043] Reference Figure 5A second spring 611 is provided in the drive hole 61. One end of the second spring 611 is connected to the drive block 81, and the other end is connected to the inner wall of the drive hole 61. During the movement of the drive block 81, the second spring 611 is compressed. During the repositioning of the feeding plate 2, the drive block 81 automatically resets under the action of the rebound force of the second spring 611. The drive block 81 controls the baffle 71 and the gathering plate 7 to automatically reset, and at the same time, the drive block 81 controls the pull rope 84 to reset, so that the pull rope 84 is straightened again, thereby realizing the function of automatic reset of the drive assembly 8.

[0044] The implementation principle of Embodiment 2 of this application is as follows: During the feeding process of the feeding plate 2, the control component 4 is activated and drives the moving plate 3 and each partition 31 to move, so that each partition 31 extends out of the guide plate 13. At this time, under the action of the partition 31, the gear shaft on the guide plate 13 is subjected to uniform flow treatment, which improves the uniformity of the gear shaft on the material channel 11 and improves the stability of the feeding device during conveying. During the resetting process of the feeding plate 2, the drive component 8 is activated and drives the gathering plate 7 to move. The gathering plate 7 gathers the gearbox in the feeding box 1, so that the gear shaft moves to the feeding plate 2, so that the feeding plate 2 can perform more accurate feeding processing on the gear shaft in the future.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
