Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 , the utility model provides a technical solution:

[0022] A stacked sheet metal gravity conveying device includes a base 1, a mounting frame 2 is installed on the top of the base 1, a first material rack 3 and a second material rack 4 are arranged inside the mounting frame 2, a transfer structure 5 is arranged on the surface of the base 1 for sequentially transferring materials inside the first material rack 3 and the second material rack 4, and a positioning structure 6 is also arranged on the base 1 for enabling the transfer structure 5 to reach below the first material rack 3 and the second material rack 4 respectively, and the positioning structure 6 enables the transfer structure 5 to move to the directly below the first material rack 3 or the second material rack 4, and then the sheet metal inside the first material rack 3 or the second material rack 4 falls onto the transfer structure 5 under the action of gravity, and finally the transfer structure 5 is driven to move by the displacement cylinder 7, thereby moving the sheet metal to a designated area position, so as to facilitate the grabbing of a robot arm in the next process.

The armrest 9 facilitates the movement of the base 1, and the electrical control box 10 is used to control the internal electrical operations.

[0024] The first unloading rack 3 includes symmetrically distributed guide rods 13 used to limit the sheet metal parts. The mounting frame 2 between the guide rods 13 is internally provided with an infrared sensor 14 used to detect whether there are sheet metal parts. Both ends of one side of the interior of the first unloading rack 3 are installed with a rear unloading stopper 15, and both ends of the other side of the interior of the first unloading rack 3 are installed with a front unloading stopper 16. The first unloading rack 3 and the second unloading rack 4 are symmetrically distributed. The infrared sensor 14 includes an infrared transmitting sensor and an infrared receiving sensor. The two sensors are placed on the shelves on both sides of the placed sheet metal parts. When the electrical control box 10 receives the signal from the infrared receiving sensor, it indicates that the sheet metal parts inside the first unloading rack 3 are about to be used up. At this time, the electrical control box 10 controls the buzzer inside it to work, thereby performing an alarm operation. The electrical control box 10 controls the work of the rear unloading stopper 15 and the front unloading stopper 16, thereby performing the operation of dropping the sheet metal parts one by one.

[0025] The rear unloading baffle 15 includes a cylinder 17 and a cylinder 2 18 installed on the mounting frame 2, a first lower baffle 19 is installed at the end of the cylinder 17, and a first upper baffle 20 is installed at the end of the cylinder 2 18, and the first upper baffle 20 is arranged above the first lower baffle 19.

[0026] The front side material unloading baffle 16 includes a cylinder three 21 and a cylinder four 22 installed on the mounting frame 2, a second lower baffle 23 is installed at the end of the cylinder three 21, and a second upper baffle 24 is installed at the end of the cylinder four 22, and the second upper baffle 24 is arranged above the second lower baffle 23.

[0027] By making cylinder three 21 and cylinder one 17 perform synchronous telescopic operation, cylinder two 18 and cylinder four 22 perform synchronous telescopic operation, so that when it is necessary to unload materials, cylinder two 18 and cylinder four 22 are operated, so that the first upper baffle 20 and the second upper baffle 24 are extended to support the sheet metal parts above the sheet metal parts below the first unloading rack 3 or the second unloading rack 4, and then cylinder three 21 and cylinder one 17 are operated to retract the first lower baffle 19 and the second lower baffle 23, so that the sheet metal parts at the bottom can fall on the transfer structure 5, and then cylinder three 21 and cylinder one 17 are operated to extend the first lower baffle 19 and the second lower baffle 23, and then cylinder two 18 and cylinder four 22 are operated to retract the first upper baffle 20 and the second upper baffle 24, so that the remaining sheet metal parts are lowered by one station as a whole, and the sheet metal parts can be lowered one by one by reciprocating.

[0028] The transfer structure 5 includes a sliding block 25. A displacement cylinder 7 capable of driving the sliding block 25 to move is installed inside the base 1. The top of the sliding block 25 is connected to a sliding bottom plate 27 through a support rod 26. Both sides of the surface of the sliding bottom plate 27 are connected to a receiving plate 29 through a cylinder 5 28. Both sides of the surface of the receiving plate 29 are distributed with limit rods 30. A proximity sensor 1 31 is installed inside the receiving plate 29. As a result, when the displacement cylinder 7 drives the sliding bottom plate 27 to move to the bottom of the first unloading rack 3 or the second unloading rack 4, the work of the cylinder 5 28 is controlled, so that the sheet metal can fall onto the receiving plate 29 along the limit rod 30, and then contact the proximity sensor 1 The surface of 31 is contacted, and after the proximity sensor 31 transmits data to the electrical control box 10, the cylinder five 28 is reset, and then the operation of the displacement cylinder 7 is controlled to move the sheet metal to the set position. A cylinder six 32 is installed at the middle position of the surface of the sliding base plate 27, and a push rod 33 that can pass through the receiving plate 29 is installed at the top of the cylinder six 32. When the sheet metal moves to the set position, the cylinder six 32 is operated, thereby lifting the sheet metal through the push rod 33, thereby facilitating the grasping operation of the robot. At the same time, the proximity sensor 31 transmits a signal to the electrical control box 10, thereby detecting whether the sheet metal leaves the transfer structure 5.

[0029] The positioning structure 6 includes an anti-collision bolt 1 35 and an anti-collision bolt 2 37. The anti-collision bolt 1 35 is arranged on the base 1 below the first unloading rack 3. A proximity switch 2 34 is installed on the base 1 on the side of the anti-collision bolt 1 35. The anti-collision bolt 2 37 is installed inside the base 1 below the second unloading rack 4. The inside of the base 1 is provided with a cylinder 7 36 capable of lifting the anti-collision bolt 2 37. A proximity switch 3 38 is installed on the side of the anti-collision bolt 2 37. When the sheet metal parts on the first unloading rack 3 need to be transported, the operation of the displacement cylinder 7 is controlled by the electrical control box 10. When the proximity switch 2 34 detects data and sends it to the electrical control box 10, it means that the transfer structure 5 is at the material receiving position below the first material rack 3. When the sheet metal parts inside the second material rack 4 need to be transported, the operation of the cylinder 7 36 is continued to be controlled, so that the anti-collision bolt 2 37 and the proximity switch 3 38 are raised, and the transfer structure 5 is blocked by the anti-collision bolt 2 37. Therefore, when the proximity switch 3 38 detects data and sends it to the electrical control box 10, it means that the transfer structure 5 is at the material receiving position below the second material rack 4.
