[0049] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0050] See Figures 1 to 9 As shown, this embodiment discloses a loading and unloading device for a kettle body stamping machine, including a first press 10 and a second press 20 arranged side by side, and further including:

[0051] Feeding conveyor belt 30 is used to transfer the kettle body 90 to be stamped once;

[0052] An oil-absorbing tank 40 is provided, which stores liquid oil and has a limiting component inside.

[0053] The transition conveyor belt 50 is located on the same side of the first press 10 and the second press 20. The transition conveyor belt 50 is used to transfer the kettle body 90 after one stamping. The two ends of the transition conveyor belt 50 are the inlet end 50a and the outlet end 50b, respectively. Limiting plates 51 are provided on both sides of the transition conveyor belt 50.

[0054] The first robotic arm 60a is used to connect the feeding conveyor belt 30 to the oil tank 40, to connect the oil tank 40 to the first press 10, and to connect the first press 10 to the feed end 50a of the transition conveyor belt 50.

[0055] The unloading conveyor belt 70 is used to transfer the kettle body 90 after secondary stamping;

[0056] The second robotic arm 60b is used to connect the discharge end 50b of the transition conveyor 50 to the second press 20 and to connect the second press 20 to the unloading conveyor 70.

[0057] In this embodiment, the spouts of the kettles 90 conveyed on the feeding conveyor belt 30, the transition conveyor belt 50, and the unloading conveyor belt 70 face upwards; the spouts of the kettles 90 conveyed to the oil-soaking tank 40 face downwards.

[0058] like Figure 8 , Figure 9 As shown, both the first robotic arm 60a and the second robotic arm 60b include:

[0059] Rotating base 61;

[0060] The multi-axis robotic arm 62 is driven to rotate horizontally by the rotating base 61;

[0061] A connecting plate 64 is installed at the free end of the multi-axis robot 62;

[0062] Four pairs of grippers 65 are symmetrically mounted at both ends of the connecting plate 64. Each pair of grippers 65 includes two grippers 65, which are driven by HFT wide-type finger cylinders 66 to move in opposite directions or in the opposite direction.

[0063] Four pairs of grippers 67, each pair including two grippers 67, are fixed to the facing end faces of two grippers 65. The facing end faces of the two grippers 67 are provided with arc-shaped grooves 68. When the HFT wide-type finger cylinder 66 drives the two grippers 65 to move towards each other, the two grippers 67 clamp the water bottle body 90; when the HFT wide-type finger cylinder 66 drives the two grippers 65 to move in the opposite direction, the two grippers 67 release the water bottle body 90. The HFT wide-type finger cylinder 66 can be an HFT series from Airtac. To quickly adapt to grippers of different specifications, the free end of the multi-axis robot 62 in this embodiment is provided with a robot-side quick-change connector 69, and the connecting plate 64 is provided with a gripper-side quick-change connector 610. The gripper-side quick-change connector 610 is compatible with the robot-side quick-change connector and can be quickly disassembled and replaced. The robot-side quick-change connector 69 and the gripper-side quick-change connector 610 in this embodiment are the commercially available OQC-020 model.

[0064] like Figures 5 to 7 As shown, there are two limiting components inside the oil-contamination tank 40, which include:

[0065] The limiting oil supply column 41 is fixedly installed on the mounting hole at the bottom of the oil tank 40. The bottom of the limiting oil supply column 41 is provided with an oil inlet hole 42. The oil inlet hole 42 starts from the lower end face of the limiting oil supply column 41 and ends at the middle of the limiting oil supply column 41. The oil inlet hole 42 is connected to the oil supply pipe and is driven by the pump. Multiple oil outlet holes 43 connected to the oil inlet hole 42 are provided around the limiting oil supply column 41.

[0066] The limiting sleeve 44 is locked and fixed to the limiting oil supply column 41. More specifically, in this embodiment, the limiting sleeve 44 is fixed to the top surface of the limiting oil supply column 41 by two bolts. A first gap 45 is provided between the bottom of the limiting sleeve 44 and the bottom of the oil-contamination groove 40, and a second gap 46 is left between the inner side wall of the limiting sleeve 44 and the outer side wall of the limiting oil supply column 41.

[0067] like Figure 6 As shown, the oil outlet holes 43 are evenly distributed around the limiting oil supply column 41. The oil outlet holes 43 are set horizontally and are all connected to the oil inlet holes 42 at the bottom.

[0068] To facilitate quick replacement, the device is equipped with a replacement platform 80. Multiple replacement platforms 80 are provided and distributed within the stroke range of the first robot 60a and the second robot 60b. At least two limit posts 81 are provided on the replacement platform 80, and the lower end face of the connecting plate 64 is provided with a limit hole 63 that matches the limit posts 81.

[0069] like Figure 4As shown, in this embodiment, the discharge port of the feeding conveyor belt 30 is provided with a limiting block 31, and the side of the limiting block 31 is provided with two limiting grooves 32, each limiting groove 32 matching the kettle body 90; the limiting groove 32 in this embodiment is a trapezoidal shape with an outward opening, which can be used for guiding and positioning, and has a high fault tolerance; since the kettle body 90 on the feeding conveyor belt 30 is manually placed, the position positioning is not accurate, so the limiting groove 32 is set to a trapezoidal shape with an outward opening.

[0070] Baffles 33 are installed on both sides of the discharge port of the feeding conveyor belt 30. Each baffle 33 is driven by a baffle cylinder 34. When the baffle 33 is driven to the extended state by the baffle cylinder 34, it can prevent the second kettle body 90 from moving into the limiting groove 32. Sensors 35 are installed on both sides of the feeding conveyor belt 30. When the first two kettle bodies 90 flow to the end (discharge port) of the feeding conveyor belt 30, the sensor 35 senses it and drives the baffle cylinder 34 to extend, which can block the subsequent kettle bodies 90 and prevent the kettle bodies 90 from connecting. This makes it easier for the gripper 65 to pick up the tool. If the kettle bodies 90 are one after another, it is inconvenient for the gripper 65 to pick them up.

[0071] The working principle of this embodiment is as follows:

[0072] The operator manually moves the kettle bodies 90 from the previous belt conveyor line (Figure 1) to the inlet of the feeding conveyor belt 30, arranging them into two rows, and conveying them towards the outlet of the feeding conveyor belt 30, with the spouts of the kettle bodies 90 facing upwards, until the first kettle body 90 of each row is moved into the two limiting slots 32 of the limiting block 31. The sensors 35 on both sides detect whether there is a kettle body 90 in the two limiting slots 32. Once a kettle body 90 enters, the blocking cylinder 34 drives the blocking plate 33 to extend, preventing the second kettle body 90 in the row from moving into the limiting slot 32, until there is a kettle body 90 in both limiting slots 32. The rotating base 61 of the first robot 60a and the multi-axis robot 62 cooperate with the two pairs of grippers 65 on the same end of the drive connecting plate 64 to grab the kettle bodies 90 in the two limiting slots 32.

[0073] The two grasped kettle bodies 90 are rotated 180° by the first robotic arm 60a, turning their upward-facing spouts downwards. The robotic arm moves the kettle bodies 90 so that their spouts are respectively fitted onto the two limiting members within the oil-contacting tank 40, bringing the bottle openings into contact with liquid oil. Liquid oil is pumped in through the oil inlet 42 at the bottom of the limiting oil supply column 41. Due to the existence of the first gap 45 and the second gap 46, the liquid oil can be discharged from the surrounding oil outlets 43, flowing into the oil-contacting tank 40 until the liquid oil in the tank reaches a certain height, at which point the injection stops. The first robotic arm 60a then rotates the kettle bodies 90 back to an upward-facing position and moves the two kettle bodies 90 to the front of the first press 10.

[0074] The two pairs of grippers 65 at the other end of the connecting plate 64 do not grip the kettle body 90. The first robot arm 60a first drives the two empty pairs of grippers 65 to take out the two kettle bodies 90 that have completed one stamping in the first press 10. After taking them out, the two kettle bodies 90 that have just been gripped are transferred to the first press 10 for one stamping. The kettle bodies 90 that have been taken out and have completed one stamping are transferred to the feed end 50a of the transition conveyor belt 50. The transition conveyor belt 50 transfers them to the discharge end 50b, waiting for the second robot arm 60b to grab them. The kettle body 90 has its mouth facing upward.

[0075] After the kettle body 90 is gripped by two pairs of grippers 65 on the same end of the second robotic arm 60b, it is moved to the front of the second press 20. At this time, the two pairs of grippers 65 on the other end do not grip the kettle body 90. Similarly, the two empty pairs of grippers 65 first take out the two kettle bodies 90 that have completed the second stamping in the second press 20, and then move the two kettle bodies 90 that have been stamped once to the second press 20 for the second stamping. The kettle bodies 90 that have been stamped twice are moved by the second robotic arm 60b to the unloading conveyor belt 70.

[0076] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
