Abstract
Description
Technical Field
[0001] This invention relates to the field of motor parts forming, and in particular to a motor end cap stacking and unloading device. Background Technology
[0002] After the motor end cover is cast, a bearing needs to be installed on it. Currently, this pressing operation is mostly completed by assembly workers using press-fitting fixtures. Throughout the process, workers need to manually operate the press-fitting fixtures and are responsible for feeding, loading, and unloading the motor end cover. The manual operation process is cumbersome and inefficient.
[0003] Existing end caps are typically stored in a stacked manner, and their structural features present challenges for material handling: the inner surface of the end cap has a bearing hole protruding at the center for mounting a bearing, a stop protruding on the inner surface, and a support lug on the outer periphery. This causes adjacent end caps to overlap axially when stacked, creating radial restraint.
[0004] To address the material discharge issue, the applicant initially attempted a push-plate discharge method, but this failed due to structural interference between the end caps. Subsequently, they tried adding a reciprocating limiting plate to restrict the descent of the second end cap from the bottom, allowing the lower end cap to overcome the interference and be pushed out by the push plate. However, because the distance between the inner surface of the end cap and the stop was too small, the limiting plate struggled to accurately position itself when moving laterally, failing to stably support the end cap and ultimately affecting the stability of the motor end cap discharge.
[0005] In summary, how to avoid radial confinement between stacked end caps and achieve stable material discharge from the end caps has become an urgent problem for researchers in this field. Summary of the Invention
[0006] The technical problem to be solved by this invention is: how to avoid radial limiting between stacked end caps and achieve stable material discharge from the end caps; To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: This invention is a motor end cap stacking and unloading device, comprising: a workbench, a conveyor belt disposed on the front side of the workbench, a guide platform disposed on the workbench, a guide hole being disposed vertically through the center of the guide platform, a shelf disposed on the guide platform, and multiple end caps stacked within the shelf, some of the end caps being located within the guide hole; a stroke groove being disposed vertically through the bottom of the side wall of the guide platform, the stroke groove communicating with the guide hole, a push plate being movably disposed within the stroke groove, and lifting members being disposed on both sides of the end of the push plate, the lifting members contacting the flange of the end cap to lift the end cap, separating the end cap from the next end cap, and pushing the next end cap onto the conveyor belt via the push plate.
[0007] Furthermore, the shelf includes: a plurality of vertically arranged connecting rods, the connecting rods being fixed on the guide platform around the axis of the guide hole, the tops of the plurality of connecting rods being connected to a common connecting ring, and the end cap being positioned between the plurality of connecting rods.
[0008] Furthermore, the bottom of the connecting ring is provided with multiple limiting rods, which pass through the connecting holes corresponding to the end cap lugs and extend vertically downward through the guide hole to the top of the travel groove.
[0009] Furthermore, the front end of the push plate is provided with an arc-shaped notch that matches the outer contour of the end cap, and a positioning notch extends rearward from the arc-shaped notch, the positioning notch being positioned and matched with one of the lugs of the end cap.
[0010] Furthermore, a pusher cylinder is provided on the rear side of the pusher plate, and the pusher cylinder drives the pusher plate to reciprocate.
[0011] Furthermore, the lifting member has a vertical wall and an inclined wall located inside the vertical wall. The inclined wall gradually moves away from the vertical wall from top to bottom. An inclined guide surface is provided on the front side of the vertical wall and the inclined wall. A support surface is formed at the top of the vertical wall and the inclined wall. An inclined guide surface is formed on the rear side of the vertical wall and the inclined wall. As the push plate moves forward, the flange of the end cap contacts the inlet surface, the support surface, and the outlet surface in sequence, lifting the end cap and then lowering it to be supported on the push plate.
[0012] Furthermore, a first sensor is provided on opposite sides of the guide table, and the sensor is used to detect whether the material is located in the travel groove.
[0013] Furthermore, a support plate is provided on the workbench, and a second sensor is provided on the support plate. The second sensor is located above the conveyor belt and is used to detect whether there is material on the conveyor belt.
[0014] Furthermore, when multiple end caps are stacked within the shelf, the outer surfaces of the end caps are stacked facing upwards.
[0015] The beneficial effects of the present invention are as follows: The present invention is a motor end cover stacking and unloading device. Through the reciprocating motion of the push plate, the push plate pushes the end cover onto the conveyor belt, while the remaining end cover can be passively lifted by the lifting component, so as to solve the problem of radial interference between adjacent end covers and realize the smooth unloading of end covers.

Detailed Implementation
[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0019] See Figure 1 , 2 The diagram shows the structure of the motor end cover 01. A bearing hole 012 is provided at the center of the inner side 011 of the end cover 01, and a protruding ring 014 is provided at the center of the outer side 013. A stop 015 is provided on the inner side 011, and the inner side 011 outside the stop 015 is a flange 016. Three lugs 017 are provided radially outward on the outer periphery of the end cover 01, and each lug 017 has a connecting hole 018. It should be noted that one side of the lug 017 is flush with the flange 016 on the inner side 011 of the end cover 01.
[0020] See Figure 3 The diagram shows a stacked structure of two motor end caps. The adjacent end caps 01 are radially limited by the cooperation of the convex ring 014 and the bearing hole 012.
[0021] See Figure 4-10To avoid the motor end caps being affected by the radial limiting between the two end caps during the unloading process, this embodiment discloses a stacking and unloading device for motor end caps 01, including: a workbench 1, a conveyor belt 2 provided on the front side of the workbench, a guide platform 3 provided on the workbench 1, a guide hole 31 provided vertically through the center of the guide platform 3, a shelf 4 provided on the guide platform 3, and multiple end caps 01 stacked in the shelf 4, such that some of the end caps 01 are located in the guide hole 31; a stroke groove 32 is provided vertically through the bottom side wall of the guide platform 31, and the height of the stroke groove 32 is preferably matched with the thickness of the end cap 01; the ... matched with the thickness of the end cap 01; the stroke groove 32 is provided vertically through the bottom side wall of the guide platform 31, and the height of the stroke groove 32 is matched with the thickness of the end cap 01; the stroke groove 32 is provided vertically through the bottom side wall of the guide platform 31, and the height of the stroke groove 32 The stroke groove 32 is connected to the guide hole 31. The end cap 01 inside the guide hole 31 can fall into the stroke groove 32 under its own weight. A push plate 5 is movably arranged in the stroke groove 32. The thickness of the push plate 5 is preferably less than the thickness of the end cap 01. If it is equal to the thickness of the end cap 01, the end of the push plate 5 will act on the side of both end caps 01 at the same time, and cannot push the end cap 01 to discharge. Lifting members 6 are provided on both sides of the end of the push plate 5. The lifting members 6 contact the flange 016 of the end cap 01 to lift the end cap 01. After the end cap 01 is separated from the next end cap 01, the next end cap 01 is pushed onto the conveyor belt 2 by the push plate 5. In this embodiment, multiple end caps 01 are stacked on the shelf 4, with some end caps 01 located in the guide hole 31. The bottom end cap 01 is supported on the workbench 1 and located in the stroke groove 32. At this time, the push plate 5 moves and approaches the conveyor belt 2. When the push plate 5 contacts the bottom end cap 01, the lifting members 6 on both sides of the end of the push plate 5 act on the flange 016 of the previous push plate 5. As the push plate 5 pushes the bottom end cap 01 forward in the stroke groove 32, the remaining end caps 01 are lifted by the lifting members 6. At this time, a certain gap is formed between the bottom end cap 01 and the end cap 01 above it. This gap 01 can accommodate the convex ring 014 and the bearing hole 01. 12. The two separate, and with the movement of the push plate 5, the bottom end cap 01 is pushed onto the conveyor belt 2. The conveyor belt 2 moves the end cap 01 to the next station for bearing assembly. Finally, with the reset of the push plate 5, the end cap 01 supported by the lifting member 6 will be at the bottom of the stacked end caps 01 and also in the stroke groove 32. The above movement is repeated to push the end caps 01 onto the conveyor belt 2 in sequence. In summary, the reciprocating movement of the push plate 5 pushes the end caps 01 onto the conveyor belt 2, while the remaining end caps 01 are passively lifted by the lifting member 6 to solve the problem of radial interference between adjacent end caps 01, so as to achieve smooth discharge of the end caps 01.
[0022] In some possible embodiments, the shelf 4 includes: a plurality of vertically arranged connecting rods 41, the connecting rods 41 being fixed on the guide platform 3 around the axis of the guide hole 31, the tops of the plurality of connecting rods 41 being connected to a common connecting ring 42, and the end cap 01 being limited between the plurality of connecting rods 41; In this embodiment, the end caps 01 are stacked vertically. Due to the limiting effect of the connecting rod 41, the end caps 01 will not collapse during the stacking process.
[0023] In some possible embodiments, the bottom of the connecting ring 42 is provided with a plurality of limiting rods 43, the limiting rods 43 passing through the connecting holes 018 corresponding to the end cap 01 lugs 017, and extending vertically downward through the guide hole 31 to the top of the stroke groove 32; In this embodiment, the end cap 01 uses the connecting hole 018 of the end cap 01's support ear 017. The limiting rod 43 passes through the connecting hole 018 to restrict the end cap 01 from rotating during the stacking process. It can also accurately drop the end cap 01 into the stroke groove 32. When the end cap 01 is disengaged from the limiting rod 43, the end cap 01 is located in the stroke groove 32. At this time, the end cap 01 can be pushed out by the push plate 5.
[0024] In some possible embodiments, the front end of the push plate 5 is provided with an arc-shaped notch 51 that matches the outer contour of the end cap 01, and a positioning notch 52 is provided extending rearward from the arc-shaped notch 51, the positioning notch 52 being positioned and matched with one of the lugs 017 of the end cap 01. In this embodiment, when one end of the push plate 5 acts on the end cover 01, the arc-shaped notch 51 matches the outer contour of the end cover 01, and the lug 017 of the end cover 01 matches the positioning notch 52. In this way, the push plate 5 will not deviate during the process of pushing the end cover 01, and accurately pushes the end cover 01 onto the conveyor belt 2, which is convenient for the subsequent precise gripping by the robot arm.
[0025] In some possible embodiments, a push cylinder 7 is provided on the rear side of the push plate 5, and the push cylinder 7 pushes the push plate 5 to reciprocate. In this embodiment, the push plate 5 is connected to the push cylinder 7, which drives the push plate 5 to reciprocate back and forth.
[0026] In some possible embodiments, the lifting member 6 has a vertical wall 61 and an inclined wall 62 located inside the vertical wall 61. The inclined wall 62 gradually moves away from the vertical wall 61 from top to bottom. An inclined guide surface 63 is provided on the front side of the vertical wall 61 and the inclined wall 62. A support surface 64 is formed at the top of the vertical wall 61 and the inclined wall 62. An inclined guide surface 65 is formed on the rear side of the vertical wall 61 and the inclined wall 62. As the push plate 5 moves forward, the flange 016 of the end cap 01 contacts the guide surface 63, the support surface 64, and the guide surface 62 in sequence, lifting the end cap 01 and then lowering it to be supported on the push plate 5. In this embodiment, the support surface 64 is a horizontal plane, and the inlet surface 63 and outlet surface 65 are inclined surfaces. The distance from the support surface 64 to the bottom of the push plate 5 is at least greater than or equal to the thickness of the end cap 01, and preferably slightly greater than the thickness of the end cap 01. As the push plate 5 moves forward, the flange 016 contacts the inlet surface 63, the support surface 64, and the outlet surface 65 in sequence. When the flange 016 acts on the inlet surface 63, the upper end cap 01 is gradually lifted. When the flange 016 acts on the support surface 64, the upper end cap 01 is completely separated from the lower end cap 01. At this time, the push plate 5 will... When the cover 01 is pushed towards the conveyor belt 2, and the flange 016 acts on the exit surface 65, the next end cover 01 and the previous end cover 01 do not overlap in the projected area. After the next end cover 01 is completely pushed onto the conveyor belt 2, the push plate 5 is reset. When the push plate 5 is reset to the initial position, the previous end cover 01 falls into the stroke groove 32 and is ready to be pushed out. The purpose of setting the inclined wall 62 is to prevent the lifting member 6 from interfering with the end cover 01 to be pushed out during the push plate 5's push-out process, so that only the inlet surface 63, support surface 64, exit surface 65 and flange are in contact. It should be noted that in this embodiment, as the push plate 5 moves linearly, the support surface 64 contacts the flange 016 earlier than the arc notch 51 contacts the side of the motor end cover 01. Thus, before the push plate 5 pushes the motor end cover 01, the previous motor end cover 01 has already been lifted by the lifting member 6.
[0027] In some possible embodiments, a first sensor 81 is provided on opposite sides of the guide table 3. The sensor 81 is used to detect whether material is located in the stroke groove 32. A support plate 9 is provided on the worktable 1. A second sensor 91 is provided on the support plate 9. The second sensor 91 is located above the conveyor belt 2. The second sensor 91 is used to detect whether material is located on the conveyor belt 2. In this embodiment, a first sensor 81 is set to detect whether the end cap falls smoothly into the travel groove 32, and a second sensor 91 is set to detect whether the end cap 01 enters the conveyor belt 2, so as to determine whether there are still end caps 01 on the shelf 4 for material discharge.
[0028] In some possible embodiments, when multiple end caps 01 are stacked within the shelf 4, the outer surfaces 013 of the end caps 01 are stacked facing upwards. In this embodiment, when the end caps 01 are stacked, the outer side 013 is stacked upwards. Since the end face of the support ear 017 is flush with the end face of the flange 016, the lifting member 6 can act on the flange 016 without interference. If the outer side 013 is stacked downwards, the lifting member 6 will be affected by the protruding part of the other end face of the support ear 017 when it moves, which will result in the inability to stably lift the end cap 01. Since the outer side of the end cap 2 on the conveyor belt faces 013, the subsequent process requires a robot to flip the end cap 01 over before the bearing can be installed.
[0029] It should be noted that since the other end caps 01 need to be lifted when the end cap 01 is discharging, this device is suitable for discharging lightweight motor end caps or plastic end caps.
