Abstract
Description
Technical Field
[0001] This invention relates to the field of stamping blanking technology, and more specifically to a fully automated automatic blanking device for stamped products. Background Technology
[0002] Stamping products rely on the pressure or shearing force exerted between the press and the die on sheet metal or other materials to stamp them into the required shape. Stamping has relatively high work efficiency and is very efficient in the mass production of parts, so it is widely used.
[0003] Existing automatic unloading devices for stamping products typically consist of a conveyor belt and an inclined plane. Finished parts are transported to the inclined plane and slide into a collection box. Subsequently, machine or manual quality inspection is performed on the stamped parts. The unloading device designed for machine quality inspection is relatively slow because it needs to screen parts for conformity. However, the production speed of stamping products is relatively fast, making it difficult to integrate quality inspection and the stamping production line at a low cost. Therefore, an automatic unloading device with a relatively fast screening speed is needed to accelerate the unloading process and facilitate integration with the stamping production line.
[0004] To address the aforementioned problems, this invention proposes a fully automated automatic unloading device for stamped products. Summary of the Invention
[0005] Technical problems to be solved
[0006] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a fully automated automatic feeding device for stamped products to solve the above-mentioned technical problems.
[0007] Technical solution
[0008] To achieve the objectives of this invention, the technical solution adopted is as follows:
[0009] A fully automated automatic feeding device for stamping products includes a first slide and a second slide. A connecting plate is installed at the bottom of the first slide, and a motor connected to the connecting plate is installed on the outside of the first slide. Air grooves are evenly distributed on the surface of the first slide. A sealing box is installed at the bottom of the first slide, and a fan communicating with its inner cavity is installed on the outside of the sealing box. A sealing plate is provided inside the sealing box, and the sealing plate seals the air grooves through protrusions distributed on its surface. Top blocks are provided at both the front and rear ends of the sealing box, and the edges of the sealing plate are simultaneously located on the inclined surfaces of the top blocks. A top plate and a connecting rod are provided at the bottom of the sealing plate, and the connecting rod extends through the sealing box to the outside. A crank mechanism is provided on the rotating shaft of the connecting plate, and the other end of the crank mechanism is connected to the connecting rod. A switch is also provided at the bottom of the first slide, located on the rotation trajectory of the crank mechanism. The switch is the switch for the fan.
[0010] Furthermore, the bottom of the connecting plate is provided with a ramp, and the top of the second slide is provided with a sloping top;
[0011] When the connecting plate and the second slide are closed, the ramp and the top of the ramp engage. The top of the second slide and the bottom of the connecting plate are both provided with bevels, and the bevels of the second slide and the bevels of the connecting plate are fully fitted together.
[0012] Furthermore, the extension directions of the first slide and the second slide are parallel and do not coincide, and the extension direction of the first slide is located below the extension direction of the second slide.
[0013] Furthermore, a guide plate is installed below the second slide rail. The guide plate is located outside the rotation radius of the connecting plate, and the angle between the guide plate and the lower half of the second slide rail is an obtuse angle.
[0014] Furthermore, the top of the sealing plate is provided with an inclined plate, the top of the inner cavity of the sealing box is equipped with a spring rod and the output end of the spring rod is supported on the inclined plate, and the bottom of the inner cavity of the sealing box is provided with a limiting plate and the limiting plate is parallel to the top plate;
[0015] The spring rod includes a guide sleeve and a spring and a sleeve rod sleeved inside the guide sleeve. The spring is elastically supported at the inner end of the sleeve rod, and the outer end of the sleeve rod abuts against the surface of the inclined plate.
[0016] Furthermore, the angle between the inclined plate and the main body of the sealing plate is an acute angle.
[0017] Furthermore, rectangular grooves are equidistantly provided between each pair of adjacent columns of protrusions on the sealing plate. The rectangular grooves on both sides are fitted onto the outer side of the top block located below. The bottom edge of the rectangular groove and the other edges of the sealing plate are simultaneously located on the inclined surface of the top block.
[0018] Furthermore, the air grooves are arranged in several rows on the first slide rail, and the length between two adjacent air grooves in each row is not equal.
[0019] Furthermore, a counter is installed on the first slide and is located vertically above the inclined surface of the first slide.
[0020] Beneficial effects: When the present invention detects that the part sliding down the first slide is a defective product, the connecting plate will be opened immediately. The defective part will fall into the gap between the first and second slides and be collected. The opening of the connecting plate will drive the sealing plate to move along the inclined surface of the first slide inside the sealed box. The edge of the sealing plate slides onto the inclined surface of the top block, causing the sealing plate to detach from the bottom inclined surface of the first slide, and the air groove is opened. At the same time, the crank mechanism presses the switch to turn on the fan during rotation. The qualified parts sliding down are attracted and slowed down, which avoids qualified parts falling into the gap between the first and second slides if the connecting plate is not closed in time during the sliding process. It does not affect the continued feeding of parts after the defective part, but quickly screens the defective parts. It is suitable for relatively fast stamping production lines.
[0021] By setting the switch on the rotation trajectory of the crank mechanism, the fan is turned on when the switch is pressed. This is mainly to avoid using a controller to control the fan, reduce the complexity of the circuit, eliminate the need for devices such as relays, reduce costs, improve operational reliability, and slightly delay the fan's opening time to avoid wasting energy when the air duct is not open.
[0022] By setting the edge of the first slide at the bottom of the inclined surface of the top block, when the sealing plate slides upward along the inclined surface of the first slide, the edge of the sealing plate will slide onto the top block at the same time, thereby separating the sealing plate from the bottom surface of the first slide and separating the protrusion from the air groove. Thus, the inner and outer sides of the air groove and the fan mechanism form a passage for airflow. The structure is simple, the process is unified as a whole, the coordination is good, and the operation is stable. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-8 The present invention is further illustrated by the embodiments:
[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fully automated automatic feeding device for stamped products includes a first slide rail 1 and a second slide rail 2. A connecting plate 3 is installed at the bottom of the first slide rail 1, and a motor 4 connected to the connecting plate 3 is installed on the outside of the first slide rail 1. Air grooves 5 are evenly distributed on the surface of the first slide rail 1. A sealing box 8 is installed at the bottom of the first slide rail 1, and a fan 9 communicating with its inner cavity is installed on the outside of the sealing box 8. A sealing plate 10 is provided inside the sealing box 8, and the sealing plate 10 is sealed by protrusions 104 distributed on its surface. The air trough 5 is sealed, and top blocks 81 are provided at both the front and rear ends of the sealing box 8. The edges of the sealing plate 10 are simultaneously located on the inclined surface of the top blocks 81. The bottom of the sealing plate 10 is provided with a top plate 101 and a connecting rod 105, and the connecting rod 105 extends through the sealing box 8 to the outside. A crank mechanism 6 is provided on the rotating shaft of the connecting plate 3, and the other end of the crank mechanism 6 is connected to the connecting rod 105. A switch 7 is also provided at the bottom of the first slide 1, located on the rotation trajectory of the crank mechanism 6. The switch 7 is the switch of the fan 9.
[0035] When a defective part is detected sliding down the first slide 1, the connecting plate 3 will be opened immediately. The defective part will fall into the gap between the first slide 1 and the second slide 2 and be collected. The opening of the connecting plate 3 will drive the crank mechanism 6 to push the connecting rod 105. As a result, the sealing plate 10 will move along the inclined surface of the first slide 1 inside the sealing box 8, and its edge will slide onto the inclined surface of the top block 81, causing the sealing plate 10 to detach from the bottom inclined surface of the first slide 1. The air groove 5 will be opened. At the same time, the crank mechanism 6 will press the switch 7 to turn on the fan 9 during the rotation. The qualified parts that slide down later will be attracted and slowed down, so as to prevent qualified parts from falling into the gap between the first slide 1 and the second slide 2 if the connecting plate 3 is not closed in time during the sliding process.
[0036] Furthermore, a ramp 31 is provided at the bottom of the connecting plate 3, and a sloping top 21 is provided at the top of the second slide 2;
[0037] When the connecting plate 3 and the second slide 2 are closed, the ramp 31 and the inclined top 21 are engaged. The top of the second slide 2 and the bottom of the connecting plate 3 are both provided with inclined openings 321, and the inclined openings 321 of the second slide 2 and the inclined openings 321 of the connecting plate 3 are fully engaged.
[0038] like Figure 3 As shown in the enlarged view, the above shape is evident. The slope 31 embraces the inclined top 21 mainly so that the slope surface of the slope 31 can be roughly located above the top of the inclined top 21. When the workpiece slides down the slope 31, it will not inevitably get stuck in the connection seam between the inclined top 21 and the slope 31, thus avoiding damage to the workpiece. The design of the inclined opening 321 of the two increases the contact area between them, thus avoiding damage to the connecting plate 3 or the second slide 2 due to edge stress.
[0039] Furthermore, the extension directions of the first slide 1 and the second slide 2 are parallel and do not coincide, and the extension direction of the first slide 1 is located below the extension direction of the second slide 2.
[0040] like Figure 3 As shown, the first slide 1 and the second slide 2 are connected by the connecting plate 3. The slid-down parts slide onto the second slide 2 through the connecting plate 3. When the connecting plate 3 is rotated downwards and disconnected from the second slide 2, the parts will be unable to slide down and jump onto the slope of the second slide 2 due to the height difference between the first slide 1 and the second slide 2, thus avoiding the error of rejecting NG products.
[0041] Furthermore, a guide plate 13 is installed below the second slide 2. The guide plate 13 is located outside the rotation radius of the connecting plate 3, and the angle between the guide plate 13 and the lower half of the second slide 2 is an obtuse angle.
[0042] The guide plate 13 mainly serves a guiding function. NG (non-compliant) items sliding down the first slide rail 1 will land on the inclined surface of the guide plate 13, thus changing their initial direction of movement, causing them to move in another direction and eventually be collected. Figure 3 As shown, the connecting plate 3 has a certain angle design. The angle design is mainly to compensate for the height difference between the first slide 1 and the second slide 2, which are not on the same plane, so that the ramp 31 and the inclined top 21 can be more easily engaged.
[0043] Furthermore, the top of the sealing plate 10 is provided with an inclined plate 102, the top of the inner cavity of the sealing box 8 is provided with a spring rod 11 and the output end of the spring rod 11 is supported on the inclined plate 102, and the bottom of the inner cavity of the sealing box 8 is provided with a limiting plate 82 and the limiting plate 82 is parallel to the top plate 101.
[0044] The spring rod 11 includes a guide sleeve 111 and a spring 112 and a sleeve rod 113 sleeved inside the guide sleeve 111. The spring 112 is elastically supported on the inner end of the sleeve rod 113, and the outer end of the sleeve rod 113 is supported on the surface of the inclined plate 102.
[0045] The spring inside the spring rod 11 will push the sealing plate 10 to slide down the slope of the first slide 1 or have a downward tendency under the pressure of the sleeve rod 113 and the inclined plate 102. The limiting plate 82 is set to block the sealing plate 10. The top plate 101 on the sealing plate 10 can eventually fit with the limiting plate 82. When the limiting plate 82 fits with the top plate 101, the edges of the sealing plate 10 are all located at the bottom of the slope of the top block 81, so that the main body of the sealing plate 10 can fit with the bottom of the first slide 1 and the protrusion 104 can be inserted into the air groove 5.
[0046] Furthermore, the angle between the inclined plate 102 and the main body of the sealing plate 10 is an acute angle;
[0047] The reason for designing it as an acute angle is that when the spring rod 11 supports the inclined plate 102, a portion of the force will be perpendicular to the bottom slope of the first slide 1. This allows the sealing plate 10 to slide along the bottom slope of the first slide 1 while simultaneously being subjected to vertical pressure along the slope of the first slide 1, so that the sealing plate 10 can fit against the bottom surface of the first slide 1. If the inclined plate 102 is only set so that the main body of the sealing plate 10 is perpendicular, then the sealing plate 10 will only be subjected to a downward thrust along the bottom slope of the first slide 1, and will not be able to press against the surface of the first slide 1, thus making it inconvenient to press the protrusion 104 into the air groove 5.
[0048] Furthermore, rectangular grooves 103 are equidistantly provided between each two adjacent columns of protrusions 104 on the sealing plate 10. The rectangular grooves 103 on both sides are fitted onto the outside of the top block 81 located below. The bottom edge of the rectangular groove 103 and the other edges of the sealing plate 10 are all located on the inclined surface of the top block 81.
[0049] like Figure 5 As shown, it can be clearly seen that the edges of the first slide 1 are all located at the bottom of the inclined surface of the top block 81. This is the initial state. Figure 4 It can be seen that the top block 81 below is located inside the rectangular groove 103, so the inner edge of the rectangular groove 103 is located at the bottom of the inclined surface of the two top blocks 81 below. When the sealing plate 10 slides upward along the inclined surface of the first slide 1, the edge of the sealing plate 10 will slide onto the top block 81 at the same time, thereby separating the sealing plate 10 from the bottom surface of the first slide 1, and the protrusion 104 separates from the air groove 5. Thus, the inner and outer sides of the air groove 5 and the fan 9 form a passage for airflow.
[0050] Furthermore, the air grooves 5 are provided in several rows on the first slide rail 1, and the length between two adjacent air grooves 5 in each row is not equal.
[0051] like Figure 1 The shape of the air groove 5 can be clearly seen. The reason for this design is that for different types of stamped parts, when some stamped parts flow down the first slide 1, their contact area with the surface of the first slide 1 is relatively small. The shorter air groove 5 is more likely to form a negative pressure surface with the parts with smaller contact area. When it cooperates with other air grooves 5, it is easier to adsorb and decelerate the parts.
[0052] Furthermore, a counter 12 is installed on the first slide rail 1 and is located vertically above the inclined surface of the first slide rail 1;
[0053] Counter 12 is used in conjunction with the controller. After each stamped part is inspected, the controller will count and number the corresponding part, and mark the corresponding NG parts. Counter 12 also counts the parts flowing through each first slide 1, and the technical specifications of each part are consistent with the numbering of the controller. Counter 12 will immediately send the count value of the currently flowing part to the controller. When the controller receives the count value of the currently flowing part as NG, it will control the motor 4 to rotate and open the connecting plate 3 located at the bottom of the first slide 1, thus creating a break in the circuit between the first slide 1 and the second slide 2. The NG parts fall onto the guide plate 13 and flow to the NG part collection point.
[0054] Working principle:
[0055] Firstly, this invention uses a counter 12 in conjunction with a controller. After each stamped part is inspected, the controller counts and numbers the corresponding parts and marks the NG parts. The counter 12 also counts the parts flowing through each first slide 1, and the counting of each part is consistent with the counting of the controller. The counter 12 immediately sends the count value of the currently flowing parts to the controller. When the controller receives the count value of the currently flowing parts as NG, it immediately controls the motor 4 to rotate and open the connecting plate 3 located at the bottom of the first slide 1. Thus, a circuit is formed between the first slide 1 and the second slide 2, and the NG parts fall onto the guide plate 13 and flow to the NG parts collection point.
[0056] When a defective part is detected sliding down the first slide 1, the connecting plate 3 will be opened immediately. The defective part will fall into the gap between the first slide 1 and the second slide 2 and be collected. The opening of the connecting plate 3 will drive the crank mechanism 6 to push the connecting rod 105. As a result, the sealing plate 10 will move along the inclined surface of the first slide 1 inside the sealing box 8, and its edge will slide onto the inclined surface of the top block 81, causing the sealing plate 10 to detach from the bottom inclined surface of the first slide 1. The air groove 5 will be opened. At the same time, the crank mechanism 6 will press the switch 7 to turn on the fan 9 during the rotation. The qualified parts that slide down later will be attracted and slowed down, so as to prevent qualified parts from falling into the gap between the first slide 1 and the second slide 2 if the connecting plate 3 is not closed in time during the sliding process.
[0057] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
