Description

Technical Field

[0001] This utility model relates to the field of production equipment technology, specifically to an automatic conveying device for punch presses based on adsorption. Background Technology

[0002] In modern industrial production, the punch press, as a key stamping press, is widely used in many sectors of national production due to its advantages such as saving materials and energy, high production efficiency, relatively low operator skill requirements, and the ability to manufacture products that are difficult to achieve with traditional machining using various molds. For example, in automobile manufacturing, many body parts such as doors and hoods, as well as housings and internal brackets in electronic equipment production, all rely on the stamping process of punch presses.

[0003] Traditional punching processes suffer from numerous drawbacks in material handling. Early punching machines relied on manual loading, requiring workers to move the products to be processed to the punching station. This method was not only extremely labor-intensive but also prone to human error leading to inaccurate loading positions, resulting in quality issues such as dimensional deviations and shape defects in the stamped products, making it difficult to guarantee a high product yield. Furthermore, manual loading was slow, severely hindering the improvement of punching machine production efficiency.

[0004] With the initial development of automation technology, some simple conveying mechanisms have been applied around punch presses. Some punch presses use conveyor belts for material transport, but these conveyor belts can only achieve simple linear movement of products and cannot accurately position or orderly buffer them. When products accumulate on the conveyor belt, they are prone to collision and compression, causing product damage. Moreover, it is difficult to perfectly match the punching rhythm of the punch press, resulting in an uneven production process. The punch press is often in a state of waiting for materials or having untimely material supply, and production efficiency still cannot be effectively improved.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] An automatic conveying device for a punch press based on adsorption includes a first conveying device, a punch press, and a second conveying device arranged in a straight line, wherein the first conveying device and the second conveying device have the same conveying direction.

[0008] The first conveying device is sequentially equipped with a stop mechanism, a gripper mechanism, and a material gripping mechanism;

[0009] The stop mechanism is used to intercept products that are being conveyed along the first conveyor and are about to reach the gripper mechanism. After the gripping mechanism takes the product away from the gripper mechanism, the stop mechanism releases the next product to be processed to the gripper mechanism.

[0010] The gripper mechanism is used to grip the product that has been conveyed to the position after being released by the stop mechanism. When the material handling mechanism approaches, the gripper mechanism releases the gripped product so that the material handling mechanism can take the product away.

[0011] The movable end of the material gripping mechanism is equipped with a suction cup for adsorbing products. The material gripping mechanism uses the suction cup to adsorb the products gripped by the gripper mechanism and transports the products to the punch press for stamping. Simultaneously or again, the suction cup is used to remove the stamped products and place them on the second conveying device.

[0012] As a further embodiment of the present invention: the material gripping mechanism has a first suction cup and a second suction cup;

[0013] The first suction cup is used to pick up the product from the gripper mechanism and transfer the product to the punch press for stamping;

[0014] The second suction cup is used to pick up the stamped product from the punch press after the punch press has completed the stamping process and transfer it to the second conveying device.

[0016] A connecting horizontal plate is mounted on the moving end of the Y-axis moving unit. The first suction cup and the second suction cup are sequentially arranged on both sides of the connecting horizontal plate along its length.

[0017] The first suction cup is located on the side away from the punch press, and the second suction cup is located on the side closer to the punch press.

[0018] As a further embodiment of this utility model: the gripper mechanism includes a pneumatic gripper body, the pneumatic gripper body has a parallel guide rail, and a first gripper finger and a second gripper finger are arranged on the parallel guide rail, forming a positioning station for the product between the first gripper finger and the second gripper finger.

[0019] As a further embodiment of this utility model: the stopping mechanism includes a gantry frame installed on the first conveying device, the top end of the gantry frame is connected to a driving component through a first connecting member, and the movable end of the driving component is connected to a limit block through a second connecting member. The driving component is used to drive the limit block to move linearly along the Y-axis.

[0020] The position of the limiting block on the second connector is adjustable.

[0021] As a further embodiment of this utility model: the first conveying device is also provided with a linear rail that acts on the product, and the stopping mechanism and the gripper mechanism are respectively corresponding to the linear rail.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This invention achieves full automation of the entire process of material conveying, positioning, gripping and transferring after stamping during punching by working in concert with a stop mechanism, a gripper mechanism and a material grabbing mechanism.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-5 In this embodiment of the present invention, an automatic conveying device for a punch press 2 based on adsorption includes a first conveying device 1, a punch press 2 and a second conveying device 3 arranged in a straight line, wherein the conveying directions of the first conveying device 1 and the second conveying device 3 are the same.

[0035] The first conveying device 1 is sequentially equipped with a stop mechanism 4, a gripper mechanism 5, and a material grabbing mechanism 6;

[0036] A stop mechanism 4 is installed on the first conveying device 1 to intercept products being conveyed along the first conveying device 1 and about to reach the gripper mechanism 5. The stop mechanism 4 includes a gantry frame 17, a drive component 19, and a limiting block 21. The gantry frame 17 is fixedly installed on the first conveying device 1. The top end of the gantry frame 17 is connected to the drive component 19 via a first connector 18. The movable end of the drive component 19 is connected to the limiting block 21 via a second connector 20. The drive component 19 is a cylinder or an electric push rod, which can drive the limiting block 21 to move linearly along the Y-axis. To accommodate products of different sizes, the position of the limiting block 21 on the second connector 20 is adjustable. Specifically, several holes spaced apart can be provided on the second connector 20, so that the limiting block 21 can select different hole positions according to the size of the product, and then bolt connection can be used to achieve fixation. It is understood that there are two limiting blocks 21. At the same time, a position sensor is also installed on the gantry frame 17 or the first conveying device 1 to detect whether the product has reached the stop position. When the position sensor detects the product, the drive component 19 drives the limiting block 21 to extend and intercept the product. After the gripping mechanism 6 takes the product from the gripper mechanism 5, the drive component 19 drives the limiting block 21 to retract and release the next product to be processed to the gripper mechanism 5.

[0037] The gripper mechanism 5 is used to grip the product that has been released by the stop mechanism 4 and transported to that position. It includes a pneumatic gripper body 13, which has a parallel guide rail. A first gripper finger 14 and a second gripper finger 15 are arranged on the parallel guide rail, forming a positioning station 16 for the product. The pneumatic gripper body 13 is connected to an external air source via an air pipe, and the air path is controlled by a solenoid valve to achieve the opening and closing action of the gripper. A position sensor is installed on the gripper body to detect the opening and closing state of the gripper, ensuring accurate gripper operation. The gripping and releasing mechanism is equipped with pressure sensors on the gripper fingers to monitor the pressure of the gripper gripping the product in real time, preventing damage to the product due to excessive pressure or drop due to insufficient pressure. When the product is released and transported to the positioning station 16 of the gripper mechanism 5 by the stop mechanism 4, the solenoid valve controls the air circuit to close the gripper, that is, the first gripper finger 14 and the second support close to grip the product. When the material gripping mechanism 6 approaches, the solenoid valve controls the air circuit to open the gripper, that is, the first gripper finger 14 and the second gripper finger 15 open to release the gripped product so that the material gripping mechanism 6 can take the product away.

[0038] The movable end of the gripping mechanism 6 is equipped with a suction cup for adsorbing products. The gripping mechanism 6 can use the suction cup to adsorb the products gripped by the clamping mechanism 5 and transport the products to the punch press 2 for stamping. Simultaneously or again, the suction cup is used to remove the stamped products and place them on the second conveying device 3. Specifically, the gripping mechanism 6 includes a mounting plate 9 mounted on the first conveying device 1, an X-axis moving unit 10 mounted on the mounting plate 9, and a Y-axis moving unit 11 mounted on the X-axis moving unit 10. Both the X-axis moving unit 10 and the Y-axis moving unit 11 adopt linear modules and are driven by servo motors through a lead screw and nut pair to achieve high-precision linear motion. A connecting cross plate 12 is installed on the moving end of the Y-axis moving unit 11. A first suction cup 7 and a second suction cup 8 are sequentially arranged on both sides of the connecting horizontal plate 12 along its length. The first suction cup 7 is used to pick up the product from the gripper mechanism 5 and transfer the product to the punch press 2 for stamping. The second suction cup 8 is used to pick up the stamped product from the punch press 2 after the punch press 2 has completed stamping and transfer it to the second conveying device 3. The first suction cup 7 is located on the side away from the punch press 2, and the second suction cup 8 is located on the side closer to the punch press 2. The first suction cup 7 and the second suction cup 8 are controlled by corresponding solenoid valves to control the suction and release actions of the suction cups. A vision sensor can also be installed on the connecting horizontal plate 12 to detect the position and posture of the product so that the gripping mechanism 6 can adjust the position and angle of the suction cups according to the detection results to accurately pick up the product.

[0039] Wherein: the first conveying device 1 and the second conveying device 3 can both be belt conveyors; in the material grabbing mechanism 6, the Y-axis moving unit 11 can be connected to the mounting plate 9 first, and the X-axis moving unit 10 can be connected to the Y-axis moving unit 11. At this time, the connecting horizontal plate 12 is installed on the moving end of the X-axis moving unit 10.

[0040] In addition, the first conveying device 1 is also equipped with a linear guide 22 that acts on the product. The stopping mechanism 4 and the gripper mechanism 5 are respectively corresponding to the linear guide 22. The product is conveyed along the linear guide 22 on the first conveying device 1 to ensure the stability and straightness of the product conveying.

[0041] When this automatic conveying equipment for a punch press 2 based on adsorption is in use, the product to be processed is first placed on the first conveying device 1, and the product is conveyed along the linear rail 22 on the first conveying device 1 towards the gripper mechanism 5; when the product approaches the stop mechanism 4, the stop mechanism 4 intercepts it, causing the product to stop in front of the positioning station 16 of the gripper mechanism 5. After the material grabbing mechanism 6 takes the product from the gripper mechanism 5, the stop mechanism 4 releases the next product to be processed to the gripper mechanism 5; when the product reaches the positioning station 16, the gripper mechanism 5 grabs the product. The gripper mechanism 5 uses a pneumatic gripper body 13, and the first gripping finger 14 and the second gripping finger 15 on its parallel guide rail close to stably fix the product at the positioning station 16.

[0042] The X-axis moving unit 10 and Y-axis moving unit 11 of the gripping mechanism 6 are driven by servo motors through a lead screw and nut pair, and move precisely to the corresponding positions. At this time, the first suction cup 7 and the second suction cup 8 on both sides of the connecting horizontal plate 12 along the length direction perform different operations. After the punch press 2 completes the previous stamping process, the first suction cup 7 moves to the gripper mechanism 5 under the drive of the X-axis moving unit 10 and the Y-axis moving unit 11. The suction force generated by the vacuum generator adsorbs the product to be stamped by the gripper mechanism 5. At the same time, the second suction cup 8 moves to the stamping station of the punch press 2 and adsorbs the product that has been stamped. After the gripping mechanism 6 completes the adsorption action, the X-axis moving unit 10 and the Y-axis moving unit 11 move again to transfer the product to be stamped by the first suction cup 7 to the stamping station of the punch press 2 for processing, and transfer the stamped product adsorbed by the second suction cup 8 to the second conveying device 3. After reaching the corresponding position, the first suction cup 7 and the second suction cup 8 release the product by stopping the vacuum generator.

[0043] The stamped products are conveyed to the subsequent processing or collection station via the second conveyor device 3, while the products to be stamped are stamped in the punch press 2. Throughout the process, the stop mechanism 4, the gripper mechanism 5 and the material grabbing mechanism 6 work closely together to continuously repeat the above process, so as to achieve efficient and stable operation of the automatic conveying equipment of the punch press 2.

[0044] In summary, this utility model achieves full automation of the material conveying, positioning, gripping and transferring after stamping during the punching process by the coordinated work of the stop mechanism 4, the gripper mechanism 5 and the material grabbing mechanism 6. No manual intervention is required, which significantly reduces the intensity of manual labor and avoids errors caused by manual operation, thereby greatly improving production efficiency.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
