Detailed Implementation
[0019] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.
[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] like Figure 1As shown, an automatic feeding and sheet-separating device includes a controller, a frame 1, a feeding trough 3, workpiece guide rods 2, a first material-supporting mechanism 5, a second material-supporting mechanism 4, and a flipping mechanism 10. The feeding trough 3 is inclinedly arranged on the frame 1, with a feeding port 20 at the upper end and a discharge port 21 at the lower end. Multiple workpiece guide rods 2 are arranged inside the feeding trough 3, with the guide rods 2 inclined and their side walls abutting against the workpieces, forming a workpiece sliding channel between the multiple guide rods 2. The first material-supporting mechanism 5 and the second material-supporting mechanism 4 are arranged at the lower part of the feeding trough 3, and the flipping mechanism 10 is arranged at the discharge port 21. Multiple stacked workpieces are placed at once through the feeding port 20, and the workpieces slide down the sliding channel along the guide rods 2 to the first material-supporting mechanism 5 and the second material-supporting mechanism 4; the first material-supporting mechanism 5 and the second material-supporting mechanism 4 separate the workpieces.
[0022] like Figures 2 to 3 As shown, the first material support mechanism 5 includes a first front cylinder 16, a first front pin 17, a first rear cylinder 12, and a first rear pin 13. The first front pin 17 and the first rear pin 13 are respectively located in front of and behind the workpiece 20, and are situated on the first diagonal 22. The first front pin 17 and the first rear pin 13 are respectively connected to the first front cylinder 16 and the first rear cylinder 12. The first front cylinder 16 and the first rear cylinder 12 respectively drive the first front pin 17 and the first rear pin 13 to extend and retract. The first front pin 17 and the first rear pin 13 are located in the same plane A. like Figures 2 to 3 As shown, the second material support mechanism 4 includes a second front cylinder 15, a second front pin 14, a second rear cylinder 19, and a second rear pin 18. The second front pin 14 and the second rear pin 18 are located in front of and behind the workpiece 20, respectively, and are located on the second diagonal 23. The second front pin 14 and the second rear pin 18 are connected to the second front cylinder 15 and the second rear cylinder 19, respectively. The second front cylinder 15 and the second rear cylinder 19 drive the second front pin 14 and the second rear pin 18 to extend and retract. The second front pin 14 and the second rear pin 18 are located in the same plane B. Plane A is located above plane B, and plane A is parallel to plane B. The first front pin 17, the first rear pin 13, the second front pin 14, and the second rear pin 18 are correspondingly arranged with the flange 24 on the workpiece 25. In the process of stacking workpieces downwards, the last workpiece from bottom to top is designated as the first and last workpieces, and the second to last workpiece is designated as the second and last workpieces. The first material support mechanism 5 is used to support or release the first and last workpieces, and the second material support mechanism 4 is used to support or release the second and last workpieces. First, the second and last workpieces slide down to the second material support mechanism 4. The second front cylinder 15 and the second rear cylinder 19 drive the second front pin 14 and the second rear pin 18 to extend. The second front pin 14 and the second rear pin 18 catch the second and last workpieces, temporarily storing the second and last workpieces and multiple workpieces above it. When the second front pin 14 and the second rear pin 18 retract, the second and last workpieces can slide down and become the first and last workpieces. Similarly, when the first and last pieces slide down to the first material support mechanism 5, the first front cylinder 16 and the first rear cylinder 12 respectively drive the first front pin 17 and the first rear pin 13 to extend and catch the first and last pieces; the first front cylinder 16 and the first rear cylinder 12 respectively drive the first front pin 17 and the first rear pin 13 to retract and release the first and last pieces, which then slide down and are sent out through the discharge port 21. like Figure 1 As shown, the flipping mechanism 10 includes a detection sensor 11, a flipping cylinder 10, a rotating seat 8, and a workpiece placement slot 7. The rotating seat 8 is located below the discharge port 21, and a workpiece placement slot 7 for carrying workpieces is provided on the rotating seat 8. The bottom of the rotating seat 8 is connected to the flipping cylinder 10, which drives the rotating seat 8 to reciprocate around the rotating shaft 9. The workpiece placement slot 7 is equipped with a detection sensor 11, which is used to detect whether there is a workpiece in the workpiece placement slot 7. The signal input terminal of the controller is connected to the detection sensor 11, and the first front cylinder 16, the first rear cylinder 12, the second front cylinder 15, the second rear cylinder 19, and the flipping cylinder 10 are respectively connected to the signal output terminal of the controller. The workpiece is sent out from the discharge port 21 and slides into the workpiece placement slot 7. The flipping cylinder 10 drives the rotating seat 8 to rotate, flipping the workpiece from an inclined state to a vertical or horizontal state, facilitating the robot arm to pick up the workpiece. The controller controls the operation of the first front cylinder 16, the first rear cylinder 12, the second front cylinder 15, the second rear cylinder 19 and the tilting cylinder 10 based on the detection signal from the detection sensor 11.
[0023] This invention discloses an automatic feeding and separating device that can simultaneously load multiple workpieces. The first and second supporting mechanisms 5 work together to separate the workpieces, and a flipping mechanism 10 rotates the workpieces to an appropriate angle before feeding them out one by one, thus achieving workpiece separation and feeding. The inclined feeding chute guides the workpieces, allowing them to slide down at an angle, protecting them, reducing noise, and minimizing floor space. Using this automatic feeding and separating device to automatically separate workpieces, in conjunction with a robotic arm for automatic loading, reduces floor space and replaces manual loading by operators.
[0024] like Figure 4As shown, it also includes a pushing mechanism 6, which includes a pushing cylinder 30, a slide 31, a pushing guide rail 33, a clamping cylinder 32, and a clamping ejector pin 34. The pushing cylinder 30 is connected to the slide 31, which is mounted on the pushing guide rail 33 and reciprocates along the guide rail 33. The clamping cylinder 32 is mounted on the slide 31 and is connected to the clamping ejector pin 30. The clamping cylinder 32 drives the clamping ejector pin 30 to extend and retract. The pushing cylinder 30 and the clamping cylinder 32 are respectively connected to the signal output terminal of the controller. There are two pushing mechanisms 6, which are mirror images of each other and symmetrically arranged on opposite sides of the unloading groove 3. When the workpiece is sent out from the discharge port 21, in order to avoid the workpieces sticking together and ensure that the workpieces slide smoothly down, the pushing mechanism 6 assists in pushing the workpieces down into the workpiece placement groove 7. During the pushing process, the clamping cylinder 32 drives the clamping pin 30 to extend and clamp the workpiece, and the pushing cylinder 30 drives the slide 31, the clamping cylinder 32, the clamping pin 30 and the workpiece to move down along the pushing guide rail 33, pushing the workpiece into the workpiece placement slot 7.
[0025] like Figure 4 As shown, the first material support mechanism 5 and the second material support mechanism 4 are mounted above the downward channel 36 via mounting brackets 35. The first material support mechanism 5 and the second material support mechanism 4 are fixedly mounted on the mounting brackets 35, a reasonable design that reduces space occupation.
[0026] like Figure 1 and Figure 2 As shown, the guide rod 2 comprises four rods, which are symmetrically arranged in front of and behind the workpiece. The cross-section of the guide rod 2 is circular. Preferably, the inclination angle between the guide rod 2 and the horizontal plane is 30° to 60°. By setting the inclination angle, the workpiece can smoothly slide down along the guide rod using its weight.
[0027] It also includes a robotic arm and an automatic welding machine, with the robotic arm positioned between the automatic feeding and sheet-separating device and the automatic welding machine. Preferably, the robotic arm is a six-axis robotic arm, used for workpiece picking, placing, and transferring. The six-axis robotic arm picks up workpieces from the workpiece placement slot, transfers them to the automatic welding machine, and places them in the welding workpiece placement position of the automatic welding machine.
[0028] like Figure 1 As shown, it also includes an electrical control box 101, which is located on the outside of the frame 1. The electrical control box 101 contains a controller, including a PLC controller. The layout is reasonable, forming an independent device, reducing floor space, and it can be placed nearby next to the welding machine.
[0029] The present invention also provides an automatic feeding and sheet separating method, according to the automatic feeding and sheet separating device, such as... Figure 5 As shown, taking multiple U-shaped workpieces that can be stacked together as an example, the steps include: Step 1: Multiple workpieces slide down the guide rod at an angle; Step 2: Drive the second front pin 14 and the second rear pin 18 to extend and support the last piece, temporarily storing the last piece and multiple workpieces above it; the first front pin 17 and the first rear pin 13 are in the extended state, supporting the first and last pieces; wherein, the second front pin 14 and the second rear pin 18 extend from the front and rear of the last piece respectively, and from a non-relative position of the last piece to support the last piece; similarly, the first front pin 17 and the first rear pin 13 extend from the front and rear of the first and last pieces, and from a non-relative position of the first and last pieces to support the first and last pieces; Step 3: Hold the last piece and multiple workpieces above it temporarily, drive the first front pin 17 and the first rear pin 13 to retract, release the first and last pieces, and the first and last pieces slide down and are sent out from the discharge port 21. Step 4: After the material is discharged from the outlet 21, the first front pin 17 and the first rear pin 13 are driven to extend. Step 5: Drive the second front pin 14 and the second rear pin 18 to retract, and the second and last pieces slide down to become the first and last pieces; support the first and last pieces by the extended first front pin 17 and the first rear pin 13, and temporarily store the first and last pieces and multiple workpieces above the first and last pieces; repeat steps 2 to 5 in a cycle, and send the workpieces out one by one from the discharge port 21. Step 6: The workpiece delivered from the discharge port 21 slides into the workpiece placement groove 7 at an angle. The flipping cylinder 10 drives the rotating seat 8 to rotate, flipping the workpiece from the inclined state to a vertical or horizontal state, making it easier for the robot to pick up the workpiece.
[0030] Furthermore, the method includes the following steps: the detection sensor 11 detects whether there is a workpiece in the workpiece placement slot 7; when a workpiece is detected in the workpiece placement slot 7, the execution of step 3 is paused; when no workpiece is detected in the workpiece placement slot 7, the execution of step 3 continues.
[0031] This invention provides an automatic feeding and sheet-separating method that allows multiple workpieces to be placed at once. A first and second supporting mechanism work together to separate the workpieces, and a flipping mechanism 10 rotates the workpieces to an appropriate angle before sending them out one by one, thus achieving sheet-separated feeding. Based on signals acquired by a detection sensor, following steps 3 to 5, multiple workpieces above the second-to-last piece are temporarily stored, while the first-to-last piece and the second-to-last piece are separated and sent out one by one. The automatic feeding and sheet-separating device automatically separates the workpieces, and the robotic arm enables automatic feeding, reducing floor space and replacing manual loading by operators.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
