Detailed Implementation

[0053] The unloading device adopts a dual-station turntable structure, which works in conjunction with the unloading basket to achieve batch unloading of parts. The unloading device is divided into two stations by a safety partition 3: the outer station is the unloading station, and the inner station is the robotic palletizing station. Both stations can work simultaneously. The unloading device consists of an upper turntable 1 and a lower drive unit 2. The lower drive unit 2 uses a variable frequency reducer to achieve precise position control. The upper turntable 1 has guiding and positioning, code recognition, error prevention detection, and emulsion discharge functions, which can effectively adapt to the operating conditions and realize batch unloading.

[0054] The upper turntable 1 with dual workstations enables the replacement of full and empty material baskets. It is equipped with a safety net 3 to separate the robot's material stacking area from the material basket replacement area. The two areas can work independently, and the robot's stacking work is not affected during the material basket replacement process, thus improving the cycle time.

[0055] The feeding device is designed specifically for liquid-filled molding parts. It can effectively recover residual emulsion liquid in the pipes and collect it. The residual emulsion liquid is discharged into the water circulation system of the equipment through the drainage pipe and the water collection pan 9, so as to achieve reuse and avoid pollution of the surrounding ground environment by residual emulsion liquid.

[0056] The feeding device is equipped with a detection device 4, which is located in the middle of the upper turntable 1, taking into full consideration the convenience of actual use. It includes four coding detection points and one direction discrimination detection point. Each detection point uses an independent electromagnetic induction switch to detect the coding points and error prevention points on the material basket. The detection information is in binary form, and the material basket number and direction are discriminated through a coding matrix.

[0057] Considering the large error in changing the material frame by overhead cranes and forklifts, guide device 5 is set up to achieve coarse guidance for long strokes and precise guidance for short strokes, thereby improving the actual operating efficiency.

[0058] This invention uses a turntable that rotates 180 degrees to switch between the batch-stacking parts baskets and empty baskets, thus enabling batch unloading.

[0059] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0060] Example 1

[0061] The structure of the unloading device is shown in the figure below. The upper turntable 1 is a dual-station design, and a safety net 3 is designed in the middle to separate the robot palletizing station and the unloading station. It is also equipped with an unloading basket.

[0062] Example 2

[0063] Based on Embodiment 1, both workstations are equipped with a guiding device 5 structure, which includes a long guide block 5.1 and a short guide block 5.2. Integrating both long and short guiding functions, it can achieve coarse guidance from 160mm to 380mm in height and fine guidance from 0 to 250mm. This ensures that when changing material baskets, the baskets can be easily placed in the workstation, reducing basket replacement time, and also serves to position the baskets, providing a positioning function for robot palletizing.

[0064] Example 3

[0065] Based on Embodiment 1, the lower drive unit 2 provides the power source for the rotation of the upper turntable 1, enabling 180-degree rotation. The two workstations are switched via rotation. The lower drive adopts a variable frequency reducer 8 structure, driving the gearbox 10 to rotate, which can adjust the rotation speed of the upper turntable 1 and achieve precise positioning. The entire rotating unloading device is leveled using adjusting screws 7 to ensure the equipment's horizontality.

[0066] Example 4

[0067] Based on Example 1, both workstations are equipped with water-blocking edges and drainage gates 6, which can effectively recover the residual emulsion in the parts. At the same time, the lower drive device 2 is equipped with a water collection tray 9, which uses water pipes to guide the residual emulsion collected by the upper turntable 1 into the water collection tray 9, recovers it, and transports it to the equipment's recycling system to avoid contaminating the ground.

[0068] Example 5

[0069] Based on Example 1, each workstation is equipped with a material basket detection device 4 to detect the material basket number and the direction of the material basket, so as to avoid problems such as mismatch between the material basket and the part and the material basket being placed backwards.

[0070] The material basket coding mechanism and orientation error prevention mechanism 17 have four coding points and one error prevention point arranged here. These work in conjunction with the unloading platform detection system to code different material baskets and use the error prevention point to determine if the current material basket's installation orientation is correct. The coding points and error prevention point are located on both the front and rear sides of the material basket.

[0071] Example 6

[0072] Based on Embodiment 1, the material basket structure in Embodiment 1 is shown in the attached drawings of the instruction manual. The basket frame 11 is welded from stainless steel. Hook seats 18 are arranged at the four corners of the basket. The external dimensions of the basket frame are 1460mm×1100mm×1320mm (W×D×H). It is made of stainless steel. The hook seat 18 structure adopts a two-sided oblique guide structure, which can be directly applied to the subsequent multi-station cleaning machine to meet the requirements of ultrasonic cleaning, rust removal, drying, air cutting and other working conditions. The basket frame is composed of multiple horizontal beams and vertical beams, which are welded from 40mm×40mm×2mm stainless steel pipes and can be used for a long time without deformation.

[0073] Two material plate fixing brackets 12 are arranged and installed on the material basket frame 11 for fixing the material plates. The material plate fixing brackets 12 are installed at an angle to keep the parts in an inclined state, so as to avoid liquid storage inside the parts. The angle can be finely adjusted as needed by adjusting screw A20.

[0074] Material plates A13 are mounted on material plate fixing bracket 12, with two plates on each side, used to hold part number 1. Material plates A13 are machined using wire cutting technology and have a part contouring function. The contouring slots 22 are inclined upward at approximately 30° and evenly spaced to ensure the part is positioned in the material basket and will not fall out. Material plate B14 is used to hold part number 2, with the same function as material plate A13, the difference being the contouring shape. The specifications of the contouring slots 22 vary depending on the shape and specifications of the part. This material plate is only used for part number 2. Both material plates A13 and B14 can be finely adjusted using adjusting screw B21. All material plates are detachable independent components and can be replaced according to the current production status of the parts, realizing the change of the material basket corresponding to the product.

[0075] The baffle mesh 15 is made of perforated stainless steel plate and is arranged at the rear end of the material basket frame 11. It is installed at an angle to prevent parts from sliding down in this direction and to restrict the parts. At the same time, the mesh structure is conducive to the discharge of liquid from the parts. The baffle mesh also provides some diagonal support for the material basket.

[0076] Example 7

[0077] Based on Embodiment 1, a forklift hole 16 is opened on one side of the bottom of the material basket for loading and unloading the basket by forklift. Through the hook seat 18 structure and the forklift hole 16 structure, the material basket can be loaded and unloaded by either an overhead crane or a forklift, and the single-sided forklift hole can avoid loading and unloading errors.

[0078] The material basket frame has multiple openings for ventilation and drainage holes 19, which ensures that the material basket will not fluctuate due to buoyancy when entering the washing machine, and can also quickly drain accumulated water to avoid environmental pollution.

[0079] A baffle net 15 is provided in the inclined direction of the material plate fixing bracket.

[0080] In summary, the present invention provides a rotary feeding device for a hydraulic press production line that adopts a 180-degree rotating turntable to achieve batch feeding, has a guiding device, a function to collect residual emulsion liquid, and a feeding basket that can constrain the position of parts.

[0081] The above embodiments have provided a detailed description of the present invention, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
