[0022] The following will be combined with the appendix Figure 1-6 This utility model will be described in further detail.

[0023] An automatic line-changing and flipping loading mechanism for a dishwasher inner drum assembly includes a frame, characterized in that: the frame includes a column 1 and a top frame 2 horizontally arranged on the top of the column 1, the top frame 2 is provided with a left-right translation mechanism, the left-right translation mechanism is provided with a right-right lifting mechanism, and the right-right lifting mechanism is provided with a clamping and flipping mechanism.

[0024] The left and right translation mechanism includes a translation linear guide rail 3 horizontally arranged on the top frame and a translation rack 4 arranged parallel to the translation linear guide rail 3. The translation linear guide rail 3 is provided with a translation plate 5 slidably connected to it. The translation plate 5 is fixed with a translation drive motor 6 and a translation gear assembly 7 meshing with the translation rack 4. The translation drive motor 6 drives the translation gear assembly 7 to rotate.

[0025] The lifting mechanism includes a lifting bracket 8 fixed on the translation plate 5, a lifting drive motor 9 fixed on the lifting bracket 8, a lifting gear 10 fixed on the output shaft of the lifting drive motor 9, and a lifting frame 11. The lifting frame 11 has vertically arranged lifting linear guide rails 12 on its left and right sides. The lifting bracket 8 has lifting sliders 13 that cooperate with the lifting linear guide rails 12. The lifting frame 11 has a vertically arranged lifting rack 14 that meshes with the lifting gear 10. The lifting frame 11 passes through the translation plate 5 and has a lifting plate 15 fixed at its bottom. The clamping and flipping mechanism is arranged on the lifting plate 15.

[0026] The clamping and flipping mechanism includes a clamping mechanism and a flipping mechanism disposed on the clamping mechanism; The clamping mechanism includes a clamping linear guide rail 16 horizontally mounted on the lifting mechanism. Clamping arms 17 are symmetrically arranged on the clamping linear guide rail 16 and slidably connected to it. The lifting mechanism is equipped with a clamping cylinder 18 for driving the clamping arms 17 to clamp. The flipping mechanism includes a rotary cylinder 19 fixed to the clamping arm 17. A rotary rack 20 is fixed to the rod head of the rotary cylinder 19. The clamping arm 17 is equipped with a flipping bearing 21, inside which is a rotating shaft 22. A flipping plate 23 is fixed to one end of the rotating shaft 22, and a rotary gear 24 meshing with the rotary rack 20 is fixed to the other end. The clamping arm 17 is equipped with a rotary rack guide assembly 25 that cooperates with the rotary rack 20. Two hydraulic buffer assemblies 26 are provided on the clamping arm 17, arranged perpendicularly to each other. Each hydraulic buffer assembly 26 includes a hydraulic buffer seat 27, on which a hydraulic buffer 28 is provided. A positioning stop nut 29 is fitted over the hydraulic buffer 28. The clamping arm 17 is provided with a clamping arm cover plate 30 on the outside and a front cover plate 31 on the upper inside of the clamping arm 17.

[0027] The bottom right side of the frame is provided with a loading platform 32, and the bottom left side of the frame is provided with a vertically arranged conveyor line 33 with a linear guide rail 3.

[0028] The working process of this equipment is as follows: First, after the dishwasher inner tub is placed on the loading platform 32, the left-right translation mechanism is activated. The translation drive motor 6, fixed on the translation plate 5, starts working, driving the translation gear assembly 7 to rotate. Since the translation gear meshes with the translation rack 4 fixed on the top frame 2, the rotation of the gear will drive the entire translation plate 5 to move precisely laterally along the translation linear guide rail 3. This action accurately positions the entire lifting and clamping unit directly above the dishwasher inner tub to be gripped.

[0029] After the translation plate 5 reaches the target position, the lifting mechanism begins to operate. The lifting drive motor 9, fixed on the lifting bracket 8, starts, driving the lifting gear 10 on its output shaft to rotate. The lifting gear 10 meshes with the lifting rack 14, which is vertically mounted on the lifting frame 11. Through the transmission of the gear and rack, the lifting frame 11, guided by the lifting linear guide rail 12 and the lifting slider 13, drives the bottom lifting plate 15 and the entire clamping and flipping mechanism to move steadily downward until the clamping arm 17 reaches a suitable height to wrap around both sides of the inner liner.

[0030] Once the lifting plate 15 is in position, the clamping mechanism begins its gripping task. The clamping cylinder 18 is activated, driving the symmetrically arranged clamping arms 17 to move synchronously towards each other along the clamping linear guide rail 16, like two fingers of a robotic arm, firmly gripping the dishwasher inner tub from both sides. The inner flip plate 23 of the clamping arm 17 ensures a large contact area with the workpiece, resulting in even force distribution and preventing damage to the workpiece.

[0031] After the flip plate 23 firmly grips the dishwasher inner tub, the entire mechanism begins to reverse: the lifting mechanism raises the inner tub to a safe height, at which point the crucial flipping mechanism begins to operate. The rotary cylinder 19, fixed on the clamping arm 17, actuates, its piston rod extending and driving the rotary rack 20 to move linearly. The rotary rack 20 meshes with the rotary gear 24, fixed on the rotating shaft 22, thus converting the linear motion of the rack into the rotational motion of the gear. The rotating shaft 22 rotates smoothly under the support of the flipping bearing 21, ultimately driving the flip plate 23, fixed at one end of the rotating shaft, and the clamped inner tub to complete a precise flip at a specific angle of 90 degrees. The end point of the flipping action is buffered and positioned by the hydraulic buffer assembly 26, effectively absorbing impact energy, ensuring a smooth stop and accurate positioning, and preventing mechanism vibration and workpiece loosening. After the flipping is completed, the left-right translation mechanism transports it to another conveyor line 33. The up-down lifting mechanism places it on the conveyor line, the clamping mechanism releases, the inner tub is precisely placed in the target position, all mechanisms reset, and preparation for the next work cycle is made.

[0032] The upper side wall of the frame is equipped with multiple guardrails 34. These guardrails 34 effectively prevent workers from accidentally entering dangerous areas through physical isolation, significantly reducing the risk of collision accidents. Their sturdy structure also serves as a warning, providing continuous and reliable safety protection for operators.

[0033] This invention integrates four major functions—translation, lifting, clamping, and flipping—into a compact frame. Through three-axis linkage, it can cover a large three-dimensional workspace, enabling cross-line material handling from line A to line B. In particular, the integrated flipping function at the end cleverly transforms horizontal linear motion into vertical rotational motion using a "rotary cylinder + rack and pinion" mechanism, resulting in a compact structure with ample power. This allows the mechanism to not only perform simple material handling but also to flip during the process, eliminating the need for a separate subsequent flipping station, simplifying the production line layout, and improving space utilization and production process continuity.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
