Technical Field

[0001] This utility model belongs to the field of automated manufacturing equipment technology, specifically relating to an automatic product flipping device. Background Technology

[0002] For products requiring processing, welding, inspection, or assembly on both sides, manual flipping is often necessary. While this method can effectively reduce costs for smaller, lighter products, it presents significant drawbacks for larger, heavier items. Firstly, manual flipping requires multiple people working together, creating considerable safety hazards due to mutual interference. Secondly, the operation demands high physical strength, which ordinary workers cannot sustain for extended periods, leading to low efficiency and potentially exacerbating safety risks and flipping accuracy errors due to fatigue.

[0003] Therefore, there is an urgent need for an automatic flipping device that can achieve automatic conveying and stable flipping. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an automatic product flipping device to solve the problems of low efficiency and high labor intensity when manually flipping products.

[0006] On one side of the two rotating trays opposite each other, a plurality of limiting modules for overlapping and fixing the trays are symmetrically arranged along their axial direction. The limiting module includes a support seat disposed on the rotating tray and a side support block that can extend and retract along the axial direction of the rotating tray.

[0010] Optionally, the lifting unit includes a lifting cylinder disposed on the mounting base plate and a top plate fixedly connected to the output end of the lifting cylinder. The lifting cylinder can drive the top plate to lift the tray and / or product placed on the conveying unit.

[0011] The bottom side of the top plate is connected to several guide shafts arranged in parallel with each other, and the guide shafts are all slidably connected to the mounting base plate in the vertical direction.

[0012] Optionally, the side support block is slidably embedded in the limiting base provided on the flip plate, and the front end of the side support block can extend out from the limiting base and cooperate with the support seat to clamp and fix the carrier plate.

[0026] like Figures 1-4As shown, an automatic product flipping device includes two flipping discs 2 that are coaxially and synchronously rotated on a mounting base 1 and are arranged opposite each other. A conveying unit is used to transport a tray 3 and / or a product 4 to the lower middle part of the two flipping discs 2. The conveying unit can be connected to the existing production process of the product 4, and a lifting unit for lifting the tray 3 and / or the product 4 is provided below the conveying unit. Several limiting modules for overlapping and fixing the tray 3 are symmetrically arranged along the axial direction on one side of the two flipping discs 2. Each limiting module includes a support base 5 on the flipping disc 2 and a side support block 6 that can extend and retract along the axial direction of the flipping disc 2. The corners of the tray 3 can be embedded into a contoured sinking groove provided on the support base 5, and the side support block 6 can press down on the tray 3 until its corners are in contact with the contoured sinking groove.

[0027] In actual operation, the conveying unit first delivers the empty pallet 3 to a fixed position at the lower center of the tilting disc 2. Then, the lifting unit lifts the empty pallet 3 upwards until all four corners of the pallet 3 are embedded in a set of support seats 5 on the same horizontal plane on both tilting discs 2. In this technical solution, each tilting disc 2 is provided with four support seats 5, and a set of support seats 5 on the same horizontal plane is composed of support seats 5 from both tilting discs 2. Specifically... Figure 1 , Figure 2 As shown, each rotating disk 2 has two support seats 5 for positioning the same carrier disk 3, and the two rotating disks 2 have a total of four support seats 5 corresponding to the four corners of the carrier disk 3. It should be noted that the contoured recessed grooves on the support seats 5 can limit the horizontal displacement of the carrier disk 3. Subsequently, the side support blocks 6 corresponding to the support seats 5 can move along the axial direction of the rotating disk 2, specifically as follows... Figure 1As shown, the side support block 6 can cooperate with the support base 5 to clamp and fix the position of the tray 3. Subsequently, the lifting unit lowers and resets, and the fixed tray 3 can also rotate 180° synchronously with the two rotating trays 2. Then, the conveying unit can transport the other tray 3 carrying the product 4 to the lower middle position of the two rotating trays 2, and the lifting unit can lift the tray 3 carrying the product 4 upward until all four corners of the tray 3 are embedded in another set of support bases 5 on the same horizontal plane on the two rotating trays 2. Then, the side support block 6 corresponding to the set of support bases 5 gradually approaches the tray 3 along the axial direction of the rotating tray 2 and moves to fix the position of the tray 3. This allows the product 4 to be firmly clamped between the two trays 3. Subsequently, the lifting unit lowers and resets again, and the rotating tray 2 drives the two trays 3 and the product 4 to rotate 180° synchronously to complete the product 4 rotation operation. Subsequently, the lifting unit can lift and support the tray 3 and product 4 located below. At this time, the side support block 6, which cooperates with the support base 5 to clamp and fix the tray 3, can retract and reset, thereby releasing the restriction on the tray 3. This allows the tray 3 and product 4 to descend vertically with the lifting unit until the conveying unit can remove the lifting unit from carrying the tray 3 and product 4. The conveying unit can then transfer the flipped product 4, thus completing one flipping operation of product 4. In this technical solution, the structural design of the tray 3 is strictly matched with the size and shape of the product 4. The tray 3 is provided with positioning features (such as positioning holes, bosses, and limiting grooves) that match the bottom and top of the product 4, ensuring the uniqueness of the product 4's position on the tray 3.

[0028] It is important to note that when the top and bottom of product 4 can be carried by the same type of carrier 3 (with identical positioning features), after the flipping operation of product 4 is completed, the two flipping trays 2 can remain in a fixed position, and the carrier 3 fixedly held above them can be used for the flipping operation of the next product 4. That is, the conveying unit can continue to convey the carrier 3 carrying another product 4 to the bottom of the two flipping trays 2, and so on, to continuously perform the flipping operation of product 4. However, when the top and bottom of product 4 need to be carried by carrier 3 of different types, the two flipping trays 2 mentioned above need to be flipped 180° again during the process of the conveying unit transferring product 4, and with the cooperation of the lifting unit and the side support block 6 corresponding to the carrier 3, the carrier 3 is transferred to the conveying unit, and the conveying unit transfers the carrier 3, so that the automatic flipping device of this technical solution is idle and waiting for the next flipping operation.

[0029] Furthermore, such as Figure 1As shown, the conveying unit includes two conveyor belts 7 that can rotate synchronously with a gap between them. The gap between the two conveyor belts 7 can be used to install a lifting unit. Each conveyor belt 7 is equipped with a limiting baffle 701 to restrict the conveying trajectory of the pallet 3, and a photoelectric sensing module (not shown) to monitor the position of the pallet 3. The two conveyor belts 7 are electrically connected, allowing for stable conveying of the pallet 3 through synchronous movement. The limiting baffles 701 on each conveyor belt 7 work together to prevent positional deviation of the pallet 3 during conveying. The photoelectric sensing module is also electrically connected to the two conveyor belts 7 and mainly consists of a light emitting unit, a light receiving unit, and a light processing unit. It can detect the real-time position of the pallet 3 on the conveyor belts 7 in a non-contact manner. Therefore, with the cooperation of the photoelectric sensing module, the conveyor belt 7, and the photoelectric sensing module, the empty tray 3 and the tray 3 carrying the product 4 can be accurately transported along a fixed movement trajectory to the lower middle position of the two flip trays 2 (the position that corresponds to the contouring sinking groove on the support base 5), so as to ensure that the lifting unit can lift the tray 3 to match the contouring sinking groove on the support base 5.

[0030] It should be noted that in this technical solution, the edge of the contour sinking trough is chamfered to guide the corner position of the carrier plate 3 to fit precisely with the contour sinking trough, so that the conveying unit can have a certain assembly error and positioning error.

[0031] Furthermore, such as Figure 1 , Figure 2 As shown, the lifting unit includes a lifting cylinder 8 mounted on a mounting base plate 1 and a top plate 9 fixedly connected to the output end of the lifting cylinder 8. The top plate 9 is arranged horizontally, meaning the lifting cylinder 8 can drive the top plate 9 to lift the carrier tray 3 and / or product 4 placed on the conveying unit. It should be noted that several parallel guide shafts 10 are connected to the bottom side of the top plate 9, and these guide shafts 10 are all slidably connected to the mounting base plate 1 in a vertical direction. This sliding relationship between the guide shafts 10 and the mounting base plate 1 restricts the movement direction of the top plate 9. Furthermore, in this technical solution, the guide shafts 10 and the mounting base plate 1 can be connected via linear flange bearings to improve displacement accuracy and smoothness, thereby ensuring the stability of the lifting unit in lifting the carrier tray 3 and / or product 4.

[0032] Furthermore, such as Figure 1 , Figure 3 , Figure 4As shown, the side support block 6 is slidably embedded in the limiting base 11 set on the rotating disk 2. The limiting base 11 can restrict the movement path of the side support block 6, so that the side support block 6 can only move along the axial direction of the rotating disk 2. That is, when the head end of the side support block 6 can extend out of the limiting base 11, it can cooperate with the support seat 5 to clamp and fix the carrier disk 3. It should be noted that the tail end of the side support block 6 is provided with an inclined dovetail groove 601, and the limiting base 11 is provided with a drive cylinder 12. The output end of the drive cylinder 12 is provided with a dovetail push rod 13 that can slide with the dovetail groove 601. In this technical solution, preferably, the movement direction of the dovetail push rod 13 is perpendicular to the movement direction of the side support block 6, specifically as shown in the figure. Figure 3 As shown, when the drive cylinder 12 drives the dovetail push rod 13 to move back and forth, since the movement trajectory of the side support block 6 is limited by the limiting base 11, the force of the dovetail push rod 13 acting on the side wall of the dovetail slide 601 will push or pull the side support block 6 to move back and forth along a fixed trajectory, so that the side support block 6 can cooperate with the support base 5 to clamp and fix the carrier plate 3 when needed, and can also release the position restriction on the carrier plate 3 in a timely manner as needed.

[0033] It should be noted that in this technical solution, if... Figure 3 , Figure 4 As shown, the side support block 6 has an inclined surface on one side edge that can press down on the carrier plate 3. That is, when the side support block 6 moves to press down on the carrier plate 3, if the carrier plate 3 is slightly offset due to installation deviation, vibration or displacement, the inclined surface on the side support block 6 will push the carrier plate 3 to the correct position through friction or pressure component, thereby correcting the positioning error of the carrier plate 3.

[0034] In this embodiment, two bearing supports 14 for mounting the rotating disks 2 are provided on the mounting base plate 1. Specifically, the rotating disks 2 and the bearing supports 14 can be connected by bushings (such as copper bushings, powder metallurgy bushings) or guide shafts 10 bearings (such as deep groove ball bearings, sliding bearings) to ensure the stability and accuracy of the rotation of the two rotating disks 2. At the same time, several connecting shafts 15 are fixedly connected between the two rotating disks 2. The connecting shafts 15 can be staggered so as not to affect the conveying unit from conveying the carrier disk 3 and / or the product 4 to the bottom of the rotating disk 2. The output shaft of one of the rotating disks 2 is driven to be connected to the output end of a servo motor 16 (including but not limited to one or more of chain drive, gear drive, and belt drive). That is, in this technical solution, the two rotating disks 2 can be driven to rotate synchronously by a single servo motor 16.

[0035] Furthermore, such as Figure 1 , Figure 2As shown, one of the rotating disks 2 has two symmetrically arranged limiting holes 201 along its axial direction, and the center point of the two limiting holes 201 is on the same straight line as the axial direction of the rotating disk 2 (coinciding with the diameter of the rotating disk 2). A limiting cylinder 18 is provided on the bearing stand 14, and the output end of the limiting cylinder 18 is provided with a limiting pin 17 that can be inserted into the limiting hole 201. That is, when the two rotating disks 2 rotate at a certain angle and wait for the lifting unit to lift the carrier disk 3 to fit into the contoured sinking groove on the support base 5, the limiting cylinder 18 can drive the limiting pin 17 to be inserted into the limiting hole 201 on the rotating disk 2, thereby ensuring that the rotating disk 2 can maintain a stable position after rotating and moving at a certain angle, and will not shift its position under the action of external force. When the side support block 6 and the support base 5 clamp and fix the carrier disk 3, the limiting cylinder 18 can drive the limiting pin 17 to be pulled out from the limiting hole 201 in time.

[0036] Working Principle: The conveying unit first delivers the empty pallet 3 to a fixed position below the tilting disc 2. The lifting unit then lifts the pallet 3 until its four corners are embedded in the contoured recesses on the four support seats 5. These contoured recesses on the support seats 5 restrict the horizontal displacement of the pallet 3, while the corresponding side supports 6 can move to cooperate with the support seats 5 to position and clamp the pallet 3. The lifting unit then lowers and resets, and the pallet 3 rotates 180° with the tilting disc 2. Next, the conveying unit delivers the pallet 3 carrying the product 4 to a fixed position below the tilting disc 2. The lifting unit lifts again, moving the pallet 3 carrying the product 4 to its four corners where it is embedded in the contoured recesses on another set of support seats 5. Simultaneously, the corresponding side supports 6 move to fix their positions, ensuring that the product 4 is securely clamped between the two pallets 3. The lifting unit then lowers and resets again, and the tilting disc 2 rotates the two pallets 3 and the product 4 180°, completing the rotation of the product 4. Next, the lifting unit can lift the lower tray 3 and product 4, while the corresponding side support block 6 can retract to release the restriction on the lower tray 3. The tray 3 and product 4 descend with the lifting unit until the conveying unit can receive the tray 3 and product 4. Finally, the conveying unit can transfer the flipped product 4 to the next stage and wait for the next product 4 flipping operation.
