Detailed Embodiment

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] A blanking device, as shown in Figure 2As shown in the figure, it includes a conveying mechanism 1, a positive and negative detection mechanism 2, a positive and negative correction mechanism 3 and a part turning mechanism 4. The conveying mechanism 1 is connected to the machining equipment and the positive and negative detection mechanism 2, and sends the machined parts to the positive and negative detection mechanism 2. The positive and negative detection mechanism 2 detects the positive and negative directions of the parts. The positive and negative correction mechanism 3 and the part turning mechanism 4 are arranged on one side of the positive and negative detection mechanism 2. The positive and negative correction mechanism 3 grabs the parts from the positive and negative detection mechanism 2 and places them on the part turning mechanism 4, and at the same time adjusts the parts in the reverse state to the positive state. Finally, the part turning mechanism 4 adjusts the parts from the horizontal state to the vertical state, and waits for the manipulator to grab the parts and put them into the carrier plate.

[0032] As Figure 2-5 shown, the conveying mechanism 1 includes a belt conveyor 11, guide plates 12 and a receiving box 13. Two guide plates 12 are provided and are arranged on both sides of the belt conveyor 11 respectively. A material channel 123 for guiding the movement of a single part is formed between the two guide plates 12, that is, the width of the material channel 123 is slightly larger than the maximum diameter of the part. The receiving box 13 is arranged on the belt conveyor 11. The receiving box 13 is recessed with a converging cavity 132, and a through falling material groove 131 is arranged at the bottom of the converging cavity 132. The converging cavity 132 is composed of inclined surfaces that are arranged on both sides of the falling material groove 131 and converge towards the falling material groove 131. The machined parts fall into the receiving box 13, and the parts are converged into the falling material groove 131 through the converging cavity 132. Among them, the falling material groove 131 is docked with the material channel 123. The other end of the material channel 123 is connected to the positive and negative detection mechanism 2. The parts are sent into the positive and negative detection mechanism 2 along the material channel 123 through the belt conveyor 11.

[0033] Among them, the guide plates 12 are adjustably installed on the belt conveyor 11. Specifically, an adjusting plate 121 is fixedly installed on the guide plate 12. An installation seat 122 is fixedly arranged on the side wall of the belt conveyor 11. An adjusting groove that cooperates with the adjusting plate 121 is arranged on the installation seat 122, and the adjusting groove is arranged vertically. A waist-shaped hole is arranged on the adjusting plate 121. The adjusting plate 121 is slidably arranged in the adjusting groove, and the adjusting plate 121 and the installation seat 122 are fixed by an adjusting bolt. It can be seen that the height position of the guide plate 12 is adjusted through the guiding cooperation of the adjusting groove and the adjusting plate 121, and the adjusting plate 121 and the installation seat 122 are fixed by the adjusting bolt.

[0034] In the above embodiment, as Figure 2-5 shown, the width of the falling material groove 131 is larger than the width of the material channel 123, and a converging section 124 is arranged between the falling material groove 131 and the material channel 123. Among them, the converging section is composed of two symmetrically arranged hypotenuses. The channel from the feeding end of the conveying mechanism 1 to the positive and negative detection mechanism 2 changes from wide to narrow and is provided with a converging section to ensure the smooth transmission of the parts.

[0035] In one embodiment, as Figure 2-5As shown, a notch 125 is provided on one side of the material guide plate 12 close to the material channel 123. The size of the notch 125 allows the fingers of the staff to reach in, and its purpose is to facilitate the staff to take out the parts in the material channel 123 for spot checks.

[0036] In one embodiment, as Figure 2-5 shown, the positive and negative detection mechanism 2 includes a mounting block 21, a first sensor 22 and a second sensor 23. A position detection area 211 and a positive and negative detection area 212 are recessed on one side of the mounting block 21. The first sensor 22 and the second sensor 23 are respectively arranged on one side of the position detection area 211 and the positive and negative detection area 212. Among them, the first sensor 22 and the second sensor 23 can use photoelectric sensors. When the part is in the reverse state, therefore, when the part reaches the position detection area 211, the first sensor 22 sends a position signal, and at the same time starts the second sensor 23 to detect. Because one end of the part entering the positive and negative detection area 212 is longer than the other end, the second sensor 23 can detect the part. On the contrary, if the part is in the positive state, when the first sensor 22 obtains the part position signal, the second sensor 23 cannot sense the part. Thus, the positive and negative detection of the part is realized.

[0037] In one embodiment, as Figure 6 shown, the positive and negative correction mechanism 3 includes a first cylinder 31, a first swing driver 32, a finger cylinder 33 and a jaw 34. The first swing driver 32 is installed on the first cylinder 31, and the first cylinder 31 is used to drive the first swing driver 32 to move vertically. The finger cylinder 33 is installed on the first swing driver 32, and the jaw 34 is installed on the finger cylinder 33. The first swing driver 32 is used to drive the finger cylinder 33 to rotate reciprocally, and the jaw 34 is located above the positive and negative detection mechanism 2. The positive and negative correction mechanism 3 realizes taking out the part from the material channel 123 and adjusting the part to the positive state when the part is in the reverse state. Specifically, after the positive and negative detection mechanism 2 finishes detection, the first cylinder 31 drives the jaw 34 to move downward, grabs the part and then resets upward; if the part is in the positive state, wait until the part flipping mechanism 4 moves below the part, and after the positive and negative correction mechanism 3 places the two parts on the part flipping mechanism 4, it resets to complete a working process. When the part is in the reverse state, the part rotates 180° through the first swing driver 32 before the part flipping mechanism 4 moves below the part.

[0038] In one embodiment, as Figure 7As shown, the part flipping mechanism 4 includes a second cylinder 41, a second swing driver 42, a flipping arm 43, and a pressing mechanism 44. The second swing driver 42 is installed on the second cylinder 41, and the second cylinder 41 is used to drive the second swing driver 42 to move horizontally. The flipping arm 43 is arranged on the second swing driver 42, and the second swing driver 42 is used to drive the flipping arm 43 to swing between the horizontal and vertical positions. A receiving cavity 431 is recessed on the flipping arm 43. The receiving cavity 431 has an open structure on two adjacent sides. When the part is placed in the receiving cavity 431, one end of it protrudes from the left end of the receiving cavity 431, so that when the flipping arm 43 flips to the vertical state, the robotic arm can easily grip the end of the part. The pressing mechanism 44 is arranged on the flipping arm 43, and the part is temporarily fixed to the flipping arm 43 through the pressing mechanism 44 to prevent the part from falling during flipping. During use, the second cylinder 41 drives the receiving cavity 431 to move below the part. After receiving the part, the second cylinder 41 resets, and then the second swing driver 42 operates to switch the part from the horizontal state to the vertical state. After the robotic arm grabs the part, the second swing driver 42 resets.

[0039] In the above embodiment, as Figure 7 shown, the pressing mechanism 44 includes a cylinder 441 and a pressing head 442. An installation hole connected to the receiving cavity 431 is provided on the side wall of the flipping arm 43. The cylinder 441 is fixed on the flipping arm 43, and the pressing head 442 is arranged in the installation hole and connected to the cylinder 441. The cylinder 441 drives the pressing head 442 to extend into the installation cavity 431 and presses the part against the inner wall on the opposite side of the receiving cavity 431. When in contact and pressing, the pressing head 442 is hidden in the installation hole to avoid affecting the part being placed in the receiving cavity 431.

[0040] In the above embodiment, as Figure 7 shown, a material guiding block 45 is provided above the receiving cavity 431. A material guiding groove 451 communicated with the receiving cavity is provided on the material guiding block 45. The length of the material guiding groove 451 is shorter than the length of the receiving cavity 431. In this embodiment, the length of the material guiding groove 451 is one-third of the part. When the gripper 34 grabs, one end of the part is pre-placed in the material guiding groove 451, and then the gripper 34 is opened, and the part falls into the receiving cavity 431 along the guidance of the material guiding groove 451.

[0041] When the present invention is in use, as Figure 1-7As shown, the parts fall into the conveying mechanism 1 from the machining equipment, and are conveyed one by one through the conveying mechanism 1 into the positive and negative detection mechanism 2. The positive and negative states of the parts are detected by the positive and negative detection mechanism 2, and then the parts are taken out of the positive and negative detection mechanism 2 by the positive and negative correction mechanism 3. If the parts are in the reverse state, the positive and negative correction mechanism 3 drives the parts to rotate horizontally by 180° to adjust to the positive state, and then the parts are placed into the part flipping mechanism 4. The part flipping mechanism 4 flips the parts from the horizontal state to the vertical state.

[0042] The above are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention; if the present invention is modified or equivalently replaced without departing from the spirit and scope of the present invention, it should be covered by the protection scope of the claims of the present invention.
