Description

Technical Field

[0001] This utility model relates to the technical field of flipping devices, and more particularly to a flipping device. Background Technology

[0002] Most existing flipping devices can only flip one material at a time, and cannot flip multiple materials simultaneously, resulting in low flipping efficiency. In addition, in pursuit of more efficient automated production, multiple materials need to be loaded onto a tray for production before and after flipping, so that multiple materials can quickly complete the corresponding processes at other corresponding workstations when they are face up or face down. Current flipping devices cannot meet this production requirement, so the existing technology needs to be improved. Utility Model Content

[0003] This utility model provides a flipping device, which mainly solves the technical problem of how to flip multiple materials so that the multiple materials are loaded on the tray before and after flipping.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A flipping device is used in conjunction with a material tray, the material tray having multiple material placement areas, each of the material placement areas having a through hole, and multiple positioning posts protruding from the periphery of each through hole.

[0006] The flipping device includes a fixed base, a drive mechanism, and two rotating modules; the two rotating modules are arranged opposite each other in the vertical direction, and both ends of the two rotating modules are rotatably connected to the fixed base; the drive mechanism connects the two rotating modules and is used to drive the two rotating modules to rotate synchronously.

[0007] Both rotating modules include a base, a first drive module, a second drive module, a locking mechanism, a tray support plate, and a material support plate. The tray support plate supports the tray. The locking mechanism is connected to one side of the tray support plate and is used to lock the tray to the tray support plate or unlock the tray so that the tray can be moved outward. The first drive module is connected to the base and the tray support plate and is used to drive the tray support plate to move up and down. The tray support plate is provided with a clearance hole. The second drive module is connected to the base and the material support plate and is used to drive the material support plate to extend upward from the clearance hole or be received downward into the clearance hole. The material support plate is provided with multiple top blocks, and the multiple top blocks correspond one-to-one with the multiple through holes on the tray.

[0008] In one of the technical solutions, both of the rotating modules further include a conveying mechanism connected to the base;

[0009] The conveying mechanism is disposed on opposite sides of the material tray plate. The conveying mechanism is used to drive the material tray to move between the material tray plate of one of the rotating modules and the material tray plate of the other rotating module. The conveying mechanism is also used to drive the material tray to move outward. The material tray plate moves upward to push the material tray away from the conveying mechanism, and moves downward to place the material tray on the conveying mechanism.

[0010] In one of the technical solutions, the rotating module further includes a lifting seat, which is slidably connected to the base in the vertical direction. The material tray is slidably connected to the lifting seat in the vertical direction. The first drive module is connected to the lifting seat and is used to drive the lifting seat to move up and down. The second drive module and the locking mechanism are both fixed on the lifting seat.

[0011] In one technical solution, the lifting platform includes a top plate, a bottom plate, and multiple first guide columns. The top plate is located above the base, and the bottom plate is located below the base. The multiple first guide columns are fixedly connected to the top plate and the bottom plate respectively. A first linear bearing that slides with the first guide columns is fixed on the base. A first drive module is connected to the bottom plate. A second drive module, the locking mechanism, and the material tray are all fixed on the top plate. The multiple first guide columns surround the outer periphery of the second drive module. The base is provided with a through hole for avoiding the second drive module. The material tray is slidably connected to the top plate.

[0012] In one of the technical solutions, multiple second guide posts are fixed to the bottom of the material pallet, and a second linear bearing that slides in conjunction with the second guide posts is fixed to the top plate. The multiple second guide posts are also arranged around the outer periphery of the second drive module.

[0013] In one of the technical solutions, the two rotating modules rotate 180° under the drive of the drive mechanism, so that the upper and lower positions of the two rotating modules alternate after rotation.

[0014] In one of the technical solutions, the locking mechanism includes a transverse cylinder, a longitudinal cylinder, and a gripper connected in sequence. When the tray is in the locked state, the gripper, driven by the longitudinal cylinder, clamps the tray together with the tray support plate.

[0015] Compared with the prior art, the flipping device provided by this utility model has at least the following beneficial effects:

[0016] Before operation, the tilting device of this solution has an empty tray (with positioning posts protruding downwards) on the upper rotating module, locked below the corresponding tray support by a locking mechanism. During operation, a tray loaded with multiple materials (with positioning posts protruding upwards) can be moved between the tray support plates of the two rotating modules by manual or automatic feeding. Then, the locking mechanism in the lower rotating module locks the newly arrived tray above the tray support plate. At this time, there is a gap between the newly arrived tray loaded with multiple materials and the tray fixed on the upper rotating module. Then, the first drive module drives the tray support plate to move, so that the upper and lower trays move closer to each other. When the multiple positioning posts on the upper tray and the multiple positioning posts on the lower tray get close enough, the second drive module in the lower rotating module drives the material support plate to rise. Multiple top blocks on the material tray lift multiple materials from the lower tray upwards until they slide along the positioning pins of the lower tray into the positioning pins of the upper tray. Then, the drive mechanism drives two rotating modules to rotate 180°, causing their positions to interchange. At this point, the materials fall back into the upper tray due to their own gravity. Finally, the first and second drive modules reset, and the upper and lower trays move away from each other vertically. Once the locking mechanism in the lower rotating module unlocks the tray, the flipped tray containing multiple materials can be removed. It should be noted that the tray from which the materials are discharged after flipping is the tray that was originally locked on the upper rotating module, while the tray that was originally feeding remains on the upper rotating module after flipping, ready to receive the materials to be flipped in the next cycle.

[0017] This solution enables the flipping of multiple materials, with all materials loaded onto the tray before and after flipping, thus meeting the high-efficiency production requirement that multiple materials need to be loaded onto the tray before and after flipping. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] This utility model embodiment provides a flipping device, which needs to be paired with... Figure 3 The tray 10 shown is used in this way. The tray 10 is provided with multiple material placement areas 101. At each material placement area 101, the tray 10 is provided with a through hole 102. Moreover, the tray 10 is provided with multiple positioning posts 103 on the outer periphery of each through hole 102. Correspondingly, the material is provided with positioning holes for the positioning posts 103 to pass through. That is, each material is positioned in the tray 10 after passing through the positioning post 103.

[0036] Please refer to the following: Figure 1 and Figure 2 The flipping device in this embodiment specifically includes a fixed base 1, a drive mechanism 2, and two rotating modules 3. The two rotating modules 3 are arranged opposite each other in the vertical direction and are structurally identical. Both ends of the two rotating modules 3 are rotatably connected to the fixed base 1. The drive mechanism 2 is connected to both rotating modules 3 and drives them to rotate synchronously. Preferably, each of the opposite ends of the two rotating modules 3 is connected to an adapter 4, which is rotatably connected to the fixed base 1. The drive mechanism 2 is connected to the adapter 4, so that when the drive mechanism 2 drives the adapter 4 to rotate, it drives the two rotating modules 3 to rotate synchronously.

[0037] Please refer to the following: Figure 1 , Figure 2 , Figure 7 and Figure 8Both rotating modules 3 include a base 31, a first drive module 32, a second drive module 33, a locking mechanism 34, a tray support 35, and a material tray 36. The base 31 is fixedly connected to the aforementioned adapter 4, meaning the base 31 is rotatable relative to the fixed base 1. The tray support 35 supports the tray 10, and the locking mechanism 34 is connected to one side of the tray support 35. The locking mechanism 34 is used to lock the tray 10 onto the tray support 35 or unlock the tray 10 so that it can be moved outwards. The first drive module 32 connects the base 31 and... The material tray 35 has a first drive module 32, which is preferably a motor-driven lead screw module. The first drive module 32 is used to drive the material tray 35 to move up and down. The material tray 35 is provided with a clearance hole 351. The second drive module 33 is also preferably a motor-driven lead screw module. The second drive module 33 is connected to the base 31 and the material tray 36. The second drive module 33 is used to drive the material tray 36 to extend upward from the clearance hole 351 or to be received downward into the clearance hole 351. The material tray 36 is provided with a plurality of top blocks 361, and the plurality of top blocks 361 correspond one-to-one with the plurality of through holes 102 on the material tray 10.

[0038] Specifically, before operation, the tilting device in this solution has an empty tray 10 on a rotating module 3 located above (e.g., ...). Figure 3 As shown, the positioning post 103 on this tray 10 (protruding downwards) is locked by the locking mechanism 34 below the corresponding tray support plate 35. During operation, the tray 10 (with the positioning post 103 protruding upwards) loaded with multiple materials can be moved between the tray support plates 35 of the two rotating modules 3 by manual or automatic feeding. Then, the locking mechanism 34 in the lower rotating module 3 locks the newly arrived tray 10 above the tray support plate 35. Figure 4 As shown, at this moment, there is a gap between the newly arrived tray 10 containing multiple materials and the tray 10 fixed on the upper rotating module 3. Then, the first drive module 32 drives the tray support plate 35 to move (this can be understood as: the tray support plate 35 can be raised by only the first drive module 32 in the lower rotating module 3, or it can be lowered by only the first drive module 32 in the upper rotating module 3, or the upper tray support plate 35 can be raised while the lower tray support plate 35 is lowering), causing the upper tray 10 and the lower tray 10 to approach each other vertically. When the multiple positioning posts 103 of the upper tray 10 and the multiple positioning posts 103 of the lower tray 10 approach each other... Figure 5When the material reaches a certain level, the second drive module 33 within the lower rotating module 3 drives the material tray 36 to rise. Multiple top blocks 361 of the rising material tray 36 extend upwards from the through-hole 102 of the lower tray 10 to lift multiple materials within the tray 10 upwards until the materials slide along the positioning post 103 of the lower tray 10 into the positioning post 103 of the upper tray 10. Then, the drive mechanism 2 drives the two rotating modules 3 to rotate 180°, causing the vertical positions of the two rotating modules 3 to be mutually... In this alternative process, multiple materials will fall into the upper tray 10 due to their own gravity (or the material tray 36 can be moved downwards by the second drive module 33 to slowly place multiple materials into the tray 10). Finally, the first drive module 32 and the second drive module 33 are reset, and the upper tray 10 and the lower tray 10 will move away from each other in the vertical direction. When the locking mechanism 34 in the lower rotating module 3 unlocks the tray 10, the flipped tray 10 containing multiple materials can be taken out. It should be noted that the tray 10 that discharges after multiple materials are flipped is the tray 10 that was originally locked on the upper rotating module 3, while the tray 10 that was originally feeding remains on the upper rotating module 3 after flipping to receive multiple materials to be flipped in the next cycle.

[0039] This solution enables the flipping of multiple materials, with all materials loaded onto the tray before and after flipping, thus meeting the high-efficiency production requirement that multiple materials need to be loaded onto the tray before and after flipping.

[0040] Please refer to the following: Figure 2 and Figure 6To improve the material feeding efficiency and the material discharge efficiency after flipping, the rotating module 3 in this embodiment also includes a conveying mechanism 37 connected to the base 31. The conveying mechanism 37 is preferably a belt conveyor and is arranged on opposite sides of the material tray 35. During operation, a material tray 10 carrying multiple materials can enter from the conveying mechanism 37 of the lower rotating module 3 and move between the material tray 35 of the lower rotating module 3 and the material tray 35 of the upper rotating module 3. After the multiple materials have finished flipping, the conveying mechanism 37 of the lower rotating module 3 drives the material tray 10 to move outward. When the tray 35 of the lower rotating module 3 moves upward under the drive of the first drive module 32 to lift the lower tray 10 and bring it closer to the upper tray 10, the lower tray 10 is actually lifted off the conveying mechanism 37 by the tray 35. This ensures that the tray 10 coming from the conveying mechanism 37 can be reliably locked on the lower tray 35 by the locking mechanism 34. Similarly, before multiple materials are flipped, the tray 10 in the upper rotating module 3 is in a state where it is pushed off the conveying mechanism 37 by the tray 35. This ensures that the upper tray 10 can be reliably locked on the upper tray 35 by the locking mechanism 34 before flipping. After multiple materials are flipped, the tray 35 moves downward to actually place the tray 10 back onto the conveying mechanism 37, so that the tray 10 that received the flipped materials can be quickly moved outward.

[0041] Please refer to the following: Figures 6 to 8 The rotating module 3 also includes a lifting seat 38, which is slidably connected to the base 31 in the vertical direction. The material tray 36 is also slidably connected to the lifting seat 38 in the vertical direction. The first drive module 32 is connected to the lifting seat 38 and drives the lifting seat 38 to move up and down relative to the base 31. The second drive module 33 and the locking mechanism 34 are both fixed to the lifting seat 38. In practice, with this structural design, when the first drive module 32 drives the lifting seat 38 to move up and down, the second drive module 33, the locking mechanism 34, the material tray 35, and the material tray 36, all directly or indirectly connected to the lifting seat 38, will move up and down along with the lifting seat 38. The second drive module 33 only drives the material tray 36 to move up and down independently. This structural design of the rotating module 3 achieves the function of driving the material tray 35 and the material tray 36 to move up and down while maintaining a simple structure.

[0042] Please refer to them again. Figures 6 to 8Assuming that both the first drive module 32 and the second drive module 33 are preferably high-precision motor-driven lead screw modules, the aforementioned lifting seat 38 is specifically designed to include a top plate 381, a bottom plate 382, ​​and multiple first guide columns 383. The top plate 381 is located above the base 31, and the bottom plate 382 is located below the base 31. The multiple first guide columns 383 are fixedly connected to the top plate 381 and the bottom plate 382 respectively to form a lifting seat 38 with good rigidity. A first linear bearing 3 is fixed on the base 31 and slides in contact with the first guide columns 383. 11. This achieves a sliding connection between the lifting seat 38 and the base 31. The first drive module 32 is connected to the base plate 382, ​​while the second drive module 33, locking mechanism 34, and material tray 35 are all fixed to the top plate 381. Multiple first guide pillars 383 surround the outer periphery of the second drive module 33, ensuring that the center of gravity of the upper part of the structure is located within the multiple first guide pillars 383, thus improving the smoothness and stability of the lifting seat 38 sliding up and down relative to the base 31. The base 31 is provided with through holes 312 to avoid the up and down movement of the second drive module 33. This specific lifting seat 38 structure has advantages such as stable lifting relative to the base 31, compact structure, and easy assembly. Based on the lifting seat 38 with this structural design, multiple second guide pillars 362 are preferably fixed at the bottom of the material tray 36, while multiple second linear bearings 384 that slide in conjunction with the second guide pillars 362 are fixed on the top plate 381, thereby achieving a sliding connection between the lifting seat 38 and the material tray 36. Meanwhile, multiple second guide posts 362 are also arranged around the outer periphery of the second drive module 33, so that the part of the second drive module 33 that drives the material pallet 36 is located within the multiple second guide posts 362, thereby improving the smoothness and stability of the second drive module 33 driving the material pallet 36 to slide up and down relative to the lifting seat 38.

[0043] Please refer to the following: Figure 7 and Figure 8 The locking mechanism 34 specifically includes a transverse cylinder 341, a longitudinal cylinder 342, and a gripper 343 connected in sequence. When the material tray 10 is in the locked state, the gripper 343, driven by the longitudinal cylinder 342, clamps the material tray 10 together with the corresponding material tray support plate 35, moving downwards or upwards. When multiple materials have been flipped and fall onto the lower material tray 10, the specific action of the material tray 10 unloading is as follows: the longitudinal cylinder 342 drives the gripper 343 to rise, then the transverse cylinder 341 drives the longitudinal cylinder 342 and the gripper 343 to move laterally away from the material tray 10, and finally the longitudinal cylinder 342 drives the gripper 343 to descend to a height lower than the material tray 10. At this time, the material tray 10 is not blocked by the gripper 343 and can move outwards along the conveying mechanism 37.

[0044] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
