Description

Technical Field

[0001] This invention relates to the field of automatic feeding technology, specifically to an automatic feeding mechanism for an automatic production line. Background Technology

[0002] An automated production line is a highly automated production system that integrates multiple production stages into a continuous production process. Automated production lines have obvious advantages: they can not only improve production capacity but also reduce costs, reduce human error, and adapt to large-scale industrial production. Automotive flanges are an important type of automotive parts. Flanges are typically used to connect two components and have a wide range of applications in automobiles. They can be used to connect drive shafts and wheels to ensure smooth power transmission.

[0003] Patent No. CN202310421561.8 discloses an automatic feeding device and method, including a sliding tube and two adjusting tubes. The sliding tube is inclined, so when the groove of the bent backrest steel wire falls into the sliding tube, the bent backrest steel wire will slide along the bottom end of the sliding tube due to gravity. During the process of the bent backrest steel wire sliding along the sliding tube, the device is also provided with two adjusting tubes, which are located on both sides of the sliding tube and are parallel to the sliding tube. In addition, the two adjusting tubes abut against the two side walls of the bent backrest steel wire. Because the two adjusting tubes abut against the two side walls of the bent backrest steel wire, the bent backrest steel wire will not shake during the process of sliding along the sliding tube. Not only will the bent backrest steel wire not fall out of the sliding tube during the sliding process, but it can also ensure that the backrest steel wire that slides to the bottom end of the sliding tube can be neatly arranged and stacked.

[0004] However, this patent also has problems such as not being able to automatically transport the stacked material frame after neatly stacking the workpieces for the next round of stacking, not being compatible with the transfer and clamping of workpieces of multiple sizes, occupying a large space, storing less material, and not being able to clean dust from the material during transfer.

[0005] Based on this, the present invention designs an automatic feeding mechanism for an automatic production line to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic feeding mechanism for an automated production line to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automatic feeding mechanism for an automated production line includes a frame. A first roller conveyor is fixedly installed on the lower side of the frame, and a second roller conveyor is fixedly installed in the middle of the frame. Multiple first proximity sensors are fixedly installed on the upper side of the second roller conveyor. A material box is provided on the second roller conveyor. A sorting device is installed on the upper side of the frame. Multiple transfer devices and a blowing device are provided on the right side of the sorting device. The transfer device includes an inclined plate, a material placement plate, positioning posts, and a clamping assembly. The inclined plate is fixedly installed on the upper side of the frame, the material placement plate is fixedly installed on the right side of the inclined plate, the multiple positioning posts are fixedly installed on the right side of the inclined plate, and the clamping assembly is installed on the right side of the inclined plate. The first proximity sensors are electrically connected to an external controller.

[0009] Furthermore, the clamping assembly includes: a first cylinder, an arc-shaped clamping plate, and a second proximity sensor. The two first cylinders are symmetrically fixedly installed on the side wall of the inclined plate along the central axis of the inclined plate. An arc-shaped clamping plate is fixedly installed at the output end of each first cylinder. The second proximity sensor is fixedly installed on the lower side of the inclined plate and is electrically connected to an external controller.

[0010] Furthermore, the sorting device includes: an X-axis servo module, a first guide rail, a first slider, a Y-axis servo module, a Z-axis servo module, and a mounting assembly. The X-axis servo module is fixedly mounted on the rear side of the frame, the first guide rail is fixedly mounted on the front side of the frame, and a plurality of first sliders are slidably connected to the first guide rail. The Y-axis servo module is fixedly mounted on the output end of the X-axis servo module, and the end of the Y-axis servo module away from the X-axis servo module is fixedly mounted on the first slider. The Z-axis servo module is fixedly mounted on the output end of the Y-axis servo module, and the mounting assembly is mounted on the output end of the Z-axis servo module.

[0011] Furthermore, the mounting assembly includes: a rotary cylinder, a gripper cylinder, and a protective block. The rotary cylinder is fixedly mounted on the output end of the Z-axis servo module, the gripper cylinder is fixedly mounted on the output end of the rotary cylinder, and the protective block is fixedly mounted on the inner side wall of the gripper of the gripper cylinder. The protective block can be made of polyurethane to prevent the gripper cylinder from scratching the surface of the flange.

[0012] Furthermore, a transfer device is installed on the right side of the frame.

[0013] Furthermore, the transfer device includes: an L-shaped frame, a second guide rail, a second slider, a support connecting plate, a lifting cylinder, and a conveying assembly. The L-shaped frame is located on the right side of the frame. Multiple second guide rails are fixedly installed on the L-shaped frame, and a second slider is slidably connected to each second guide rail. The lifting cylinder is fixedly installed on the L-shaped frame, and the support connecting plate is fixedly installed on the second slider. The middle side of the support connecting plate is fixedly connected to the output end of the lifting cylinder, and the conveying assembly is installed on the support connecting plate.

[0014] Furthermore, the conveying assembly includes: a roller conveyor, a baffle, and a third proximity sensor. The roller conveyor is fixedly installed at the end of the support connecting plate away from the second slider. The baffle is fixedly installed on the right side of the roller conveyor and is used to block the material box from moving out of the roller conveyor. The third proximity sensor is fixedly installed on the side wall of the baffle and is electrically connected to an external controller.

[0015] Furthermore, the purging device includes a purging hole and a purging nozzle. The inclined plate is provided with a purging hole, and a plurality of the purging nozzles are fixedly installed on the frame by a bracket, with one of the purging nozzles being close to the purging hole.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention uses a material box to transport materials from a second roller conveyor on the side of the frame to a first proximity sensor. The first proximity sensor detects the material box approaching and transmits an electrical signal to an external controller. The external controller then stops the second roller conveyor for a period of time. The start-up time of the second roller conveyor can be controlled by the loading time. The second roller conveyor then resumes operation, transporting the full material box to the roller conveyor of the transfer device. A third proximity sensor detects the material box on the roller conveyor and transmits an electrical signal to the external controller. The external controller then controls the output end of a lifting cylinder to move downwards. This downward movement of the lifting cylinder causes a supporting connecting plate to move downwards, which in turn causes the roller conveyor to move downwards. The downward movement of the roller conveyor causes the material box to move downwards. The start-up time of the roller conveyor is controlled by the downward movement time of the material box. Once started, the roller conveyor transports the material box to the first roller conveyor on the lower side of the frame. This facilitates the neat stacking of workpieces and the automatic transport of the stacked material frames for the next round of stacking. The overlapping arrangement of the first and second roller conveyors results in a small equipment footprint while maximizing storage and buffer material capacity.

[0018] The flange is delivered to the material placement plate of the transfer device via an external robotic arm. A positioning post positions the lower side of the flange to prevent it from slipping. A second proximity sensor detects the flange and transmits an electrical signal to an external controller. The external controller then activates a first cylinder, which extends its output end to move an arc-shaped clamping plate towards the flange, clamping it in place. The arc-shaped clamping plate holds the arc-shaped portion of the flange, facilitating the adaptation to various flange specifications and enabling quick fixing of different types of flanges, thus simplifying loading after transfer. A purge nozzle connected to an external air blower blows air through its nozzles to clean the side of the flange closest to the inclined plate, while other purge nozzles blow air to clean the other side of the flange. This facilitates dust removal during transfer and ensures the flange remains clean after loading. This invention allows for the automatic transport and stacking of workpieces after neat stacking, supporting the transfer and clamping of workpieces of multiple sizes, occupying minimal space, and enabling dust removal during transfer.

[0032] Example 1

[0033] Please see Figures 1-7 In this embodiment of the invention, the automatic feeding mechanism of the automatic line includes a frame 1. A first roller conveyor 2 is fixedly installed on the lower side of the frame 1. A second roller conveyor 3 is fixedly installed on the middle side of the frame 1.

A plurality of positioning posts 10 are fixedly installed on the right side of the inclined plate 8. The clamping assembly is installed on the right side of the inclined plate 8. The first proximity sensors 4 are electrically connected to an external controller.

[0034] The clamping assembly includes: a first cylinder 11, an arc-shaped clamping plate 12, and a second proximity sensor 13. The two first cylinders 11 are symmetrically fixedly installed on the side wall of the inclined plate 8 along the central axis of the inclined plate 8. An arc-shaped clamping plate 12 is fixedly installed at the output end of each first cylinder 11. The second proximity sensor 13 is fixedly installed on the lower side of the inclined plate 8 and is electrically connected to an external controller.

[0035] The flange is delivered to the material placement plate 9 of the transfer device 7 by an external robotic arm. The positioning column 10 positions the lower side of the flange and prevents it from slipping. The second proximity sensor 13 detects the flange and transmits an electrical signal to the external controller. The external controller controls the first cylinder 11 to start. The output end of the first cylinder 11 extends and drives the arc-shaped clamping plate 12 to move towards the flange, clamping the flange. The arc-shaped clamping plate 12 clamps the arc-shaped part of the flange, which is conducive to adapting to various specifications of flanges, facilitating the quick fixing of different types of flanges, and making it convenient for loading after transfer.

[0036] The sorting device 6 includes: an X-axis servo module, a first guide rail, a first slider, a Y-axis servo module, a Z-axis servo module, and a mounting assembly. The X-axis servo module is fixedly installed on the rear side of the frame 1, the first guide rail is fixedly installed on the front side of the frame 1, and a plurality of first sliders are slidably connected to the first guide rail. The Y-axis servo module is fixedly installed on the output end of the X-axis servo module, and the end of the Y-axis servo module away from the X-axis servo module is fixedly installed on the first slider. The Z-axis servo module is fixedly installed on the output end of the Y-axis servo module, and the mounting assembly is installed on the output end of the Z-axis servo module.

[0037] The mounting assembly includes a rotary cylinder 14, a gripper cylinder 15, and a protective block 16. The rotary cylinder 14 is fixedly mounted on the output end of the Z-axis servo module, the gripper cylinder 15 is fixedly mounted on the output end of the rotary cylinder 14, and the protective block 16 is fixedly mounted on the inner side wall of the gripper of the gripper cylinder 15. The protective block 16 can be a polyurethane block to prevent the gripper cylinder 15 from scratching the surface of the flange.

[0038] The X-axis servo module, Y-axis servo module, and Z-axis servo module are activated to transport the placement component to position 9 of the material placement plate. The gripper cylinder 15 is activated to clamp the flange. Then, the X-axis servo module, Y-axis servo module, and Z-axis servo module place the clamped flange into the material box 5, which is conducive to the even stacking of the flange.

[0039] Example 2

[0040] like Figure 1-7 As shown, in a preferred embodiment of the present invention, a transfer device is installed on the right side of the frame 1;

[0041] The transfer device includes: an L-shaped frame 17, a second guide rail, a second slider, a support connecting plate 18, a lifting cylinder 19, and a conveying assembly. The L-shaped frame 17 is located on the right side of the frame 1. Multiple second guide rails are fixedly installed on the L-shaped frame 17, and a second slider is slidably connected to each second guide rail. The lifting cylinder 19 is fixedly installed on the L-shaped frame 17, and the support connecting plate 18 is fixedly installed on the second slider. The middle side of the support connecting plate 18 is fixedly connected to the output end of the lifting cylinder 19. The conveying assembly is installed on the support connecting plate 18.

[0042] The conveying assembly includes: a roller conveyor 20, a baffle 21, and a third proximity sensor 22. The roller conveyor 20 is fixedly installed at the end of the support connecting plate 18 away from the second slider. The baffle 21 is fixedly installed on the right side of the roller conveyor 20 and is used to block the material box 5 from moving out of the roller conveyor 20. The third proximity sensor 22 is fixedly installed on the side wall of the baffle 21 and is electrically connected to an external controller.

[0043] Material box 5 is conveyed from the second roller conveyor 3 on the side of the frame 1 to the position of the first proximity sensor 4. The first proximity sensor 4 detects that material box 5 is approaching and transmits an electrical signal to the external controller. The external controller controls the second roller conveyor 3 to stop for a period of time. The start time of the second roller conveyor 3 can be controlled by the loading time. Then, the second roller conveyor 3 continues to convey the full material box 5 to the roller conveyor 20 of the transfer device conveying assembly. The third proximity sensor 22 detects the material box 5 on the roller conveyor 20 and transmits an electrical signal to the external controller. The external controller controls the output end of the lifting cylinder 19 to move downward. The lifting cylinder 19 moves downward, causing the support connecting plate 18 to move downward. The support connecting plate 18 moves downward, causing the roller conveyor 20 to move downward. The roller conveyor 20 moves downward, causing the material box 5 to move downward. The starting time of the roller conveyor 20 is controlled by the downward movement time of the material box 5. When the roller conveyor 20 starts, it transports the material box 5 to the first roller conveyor 2 on the lower side of the frame 1. This is beneficial for the workpieces to be neatly stacked and for the automatic transport of the stacked material frame to the next round of stacking. The superposition of the first roller conveyor 2 and the second roller conveyor 3 makes the equipment occupy less space and store more buffer materials.

[0044] The purging device includes: a purging hole and a purging nozzle 23. The inclined plate 8 is provided with a purging hole, and a plurality of the purging nozzles 23 are fixedly installed on the frame 1 by a bracket, with one of the purging nozzles 23 closely attached to the purging hole.

[0045] The purge nozzle 23 is connected to an external air blower. It blows air through the purge hole to clean the side of the flange near the inclined plate 8. Other purge nozzles 23 blow air to clean the other side of the flange. This is beneficial for cleaning dust from materials during transfer and for keeping the flange clean after loading.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
