Description

Technical Field

[0001] The utility model relates to the technical field of stamping production lines, in particular to an automatic stamping material receiving and stacking device. Background Art

[0002] During the continuous stamping process of the punching machine, the processes of unloading, collecting and placing the processed parts are mainly performed manually. The personnel frequently raise their hands and bend over to place the frames and materials. The movements are monotonous and rigid and repetitive. The workers are easily fatigued and even prone to accidental injuries. There are problems of high labor intensity and high safety risks.

[0003] At present, robotic devices for transfer and stacking are widely used in various industries. The main difference in their design is that the gripping end of the robot can match the shape of the workpiece, thereby carrying out large-scale production.

[0004] However, in stamping production lines, due to the diverse personalized designs and sizes of stamping workpieces, traditional robotic devices designed for a single product are difficult to adapt to the diverse needs of stamping production lines.

[0005] In addition, the production of parts on the assembly line mainly relies on the production rhythm to control the operating frequency of the robot. Due to the rhythm of the production rhythm, the stamping production line is flexible and changeable, and the working rhythm of the robot needs to be adjusted to adapt to different production situations.

[0006] In order to solve the above technical problems, those skilled in the art are looking for new solutions. Utility Model Content

[0007] The purpose of the utility model is to address the deficiencies of the prior art and thus provide a stamping automatic material receiving and stacking device suitable for a stamping production line and with a variable and controllable production rhythm.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a stamping automatic material collection and stacking device, including a first conveyor belt, a slide, a second conveyor belt, a position detection sensor, a manipulator, a blanking station and a control host;

[0009] The first conveyor belt is higher than the second conveyor belt as a whole, the tail end of the first conveyor belt is connected to the upper end of the slide, and the lower end of the slide is connected to the head end of the second conveyor belt;

[0010] A certain position of the second conveyor belt is set as a grabbing station, and the position detection sensor is installed at the grabbing station or upstream of the second conveyor belt to sense whether the stamping workpiece is in place;

[0011] An electromagnetic adsorption gripper is provided at the action end of the manipulator, and the control host is connected to the position detection sensor and the manipulator respectively, and drives the manipulator to switch between the grabbing station and the blanking station according to the detection signal of the position detection sensor.

[0012] Preferably, the position detection sensor is an infrared radiation sensor.

[0013] Preferably, the position detection sensor is a laser beam sensor.

[0014] Preferably, the position detection sensor is a contact sensor.

[0015] Preferably, the electromagnetic adsorption gripper includes a rectangular electromagnetic adsorption block.

[0016] Preferably, the electromagnetic adsorption gripper includes a plurality of electromagnetic adsorption blocks arranged in parallel.

[0017] Preferably, the electromagnetic adsorption block is connected to the front end of the manipulator arm through a guide column and a safety spring.

[0018] Preferably, a plurality of parallel electromagnetic adsorption blocks are connected to the front end of the manipulator arm in a one-to-one correspondence, and each electromagnetic adsorption block is connected to the front end of the manipulator arm through a guide column and a safety spring.

[0019] Preferably, the workpiece grasped by the manipulator is a plate-like structure or a long strip structure or a profile.

[0020] Preferably, there is at least one manipulator, and the manipulator is at least a three-axis manipulator.

[0021] Compared with the existing technology, the present invention has substantial characteristics and progress. Specifically, based on the traditional stacking robot, the present invention designs the working end of the robot to be in the form of electromagnetic adsorption in view of the characteristics of the stamping assembly line. It can be used for most metal stamping workpieces, which can be fixed by electromagnetic adsorption. Therefore, there is no need to consider the specific shape, size and specifications of the stamping workpiece. It is only necessary to consider the weight factor and whether the adsorption point is reasonable. This realizes the versatility of the robot in the production of stamping workpieces and ultimately improves efficiency.

[0022] Furthermore, a multi-stage conveyor belt is designed to cooperate with the transfer of stamping workpieces, and a position detection sensor is added as a detection signal for whether the stamping workpiece is in place. One-to-one detection and grasping replaces the traditional solution of relying on production rhythm to achieve grasping rhythm. This makes it unnecessary to consider the rhythm problem during the operation of the robot, and can adapt to various situations of the stamping production line, thereby improving the grasping success rate.

[0028] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0029] like Figures 1-4 As shown, a stamping automatic material collection and stacking device includes a first conveyor belt 2, a slide 3, a second conveyor belt 4, a position detection sensor 5, a robot 1, a blanking station 6 and a control host (not shown).

[0030] The first conveyor belt 2 is higher than the second conveyor belt 4 as a whole. The tail end of the first conveyor belt 2 is connected to the upper end of the slide 3, and the lower end of the slide 3 is connected to the head end of the second conveyor belt 4. After the stamping is completed, the stamping workpiece 7 can slide from the first conveyor belt 2 and the slide 3 to the second conveyor belt 4, and then be transferred to the grabbing station for grabbing.

[0031] A certain position of the second conveyor belt 4 is set as a grabbing station 8, and the position detection sensor 5 is installed at the grabbing station 8 or upstream of the second conveyor belt 4 to sense whether the stamping workpiece 7 is in place.

[0032] The active end of the manipulator 1 is provided with an electromagnetic adsorption gripper 11, and the control host is connected to the position detection sensor 5 and the manipulator 1 respectively, and drives the manipulator 1 to switch between the grabbing station 8 and the blanking station 6 according to the detection signal of the position detection sensor 5. In this embodiment, the blanking station 6 places the material frame.

[0033] The number of the manipulator is at least one, and the manipulator is at least a three-axis manipulator, which is arranged on one side of the second conveyor belt 4 .

[0034] In this embodiment, the position detection sensor 5 is an infrared beam sensor. In other preferred embodiments, the position detection sensor is a laser beam sensor or a contact sensor. The specific sensor type to be used can be determined based on the shape and path of the workpiece.

[0035] In this embodiment, the electromagnetic adsorption gripper 11 includes a rectangular electromagnetic adsorption block. The adsorption surface of the electromagnetic adsorption block is flat, which can adapt to the adsorption of most stamping parts. Since the active surface is flat, the adsorption surface area is large and the adsorption force can be guaranteed.

[0036] In other embodiments, the electromagnetic adsorption gripper includes a plurality of electromagnetic adsorption blocks arranged in parallel. The electromagnetic adsorption blocks arranged in this manner have more diverse usage scenarios. On the one hand, they can adsorb multiple stamping workpieces arranged in a row. On the other hand, they can serve as the adsorption surface of stamping workpieces with a larger surface area, thereby avoiding a single electromagnetic adsorption block from being designed too large, thereby avoiding excessive power consumption or excessive manufacturing costs of the electromagnetic adsorption blocks.

[0037] In order to avoid impact damage to the surface of the stamped workpiece during the grasping process, the electromagnetic adsorption block 12 is connected to the front end 13 of the manipulator's arm through a guide column 14 and a safety spring 15 to provide a buffering force.

[0038] Similarly, in the row-arranged scheme, several parallel electromagnetic adsorption blocks are connected one by one to the front end of the manipulator's robotic arm, and each electromagnetic adsorption block is connected to the front end of the manipulator's robotic arm through a guide column and a safety spring.

[0039] The device is more suitable for stamping workpieces with plate-like structures, long strip structures or profile structures.

[0040] Working principle description:

[0041] After the stamping workpiece is processed at the stamping station, it is transferred to the slide 3 by the first conveyor belt, slides to the second conveyor belt 4 along the slide 3, and then transferred to the grabbing station 8 along the second conveyor belt 4. The position detection sensor 5 senses that the stamping workpiece 7 is in place and sends a signal to the controller. The controller executes the corresponding instructions according to the built-in programming software, drives the manipulator to move to the grabbing station 8 and starts the electromagnetic adsorption gripper 11. After grabbing the stamping workpiece, it is transferred to the blanking station 6, and then the magnetic force of the electromagnetic adsorption gripper 11 is disconnected, so that the stamping workpiece 7 is neatly placed at the blanking station 6. After stacking the set number of layers and height, it is transferred to other processes through other transfer equipment.

[0042] Finally, it should be noted that: The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
