Description

Technical Field

[0001] The utility model belongs to the technical field of automatic feeding equipment, and particularly relates to a bin-type feeding device with a vision detection function. Background Art

[0002] In the field of automatic production, the finished processing of workpieces often requires multiple processes. Therefore, during the processing and loading / unloading of workpieces, the workpieces need to be evenly placed at specific intervals in the next production line.

[0003] In many current production lines, there are many drawbacks. The main defects are as follows: During the processing of materials, manual feeding is required, and workers need to stay beside the production line for a long time, unable to do other things, which consumes labor and results in low production efficiency. Moreover, for stacked workpieces, the accuracy requirements for the placement position of materials in the production line are extremely high. When relying on manual feeding and ordinary feeding equipment, not only is the manual efficiency low, but also the ordinary feeding equipment lacks a camera for detecting the position of workpieces, resulting in low positioning accuracy of workpiece feeding, inaccurate picking and placing of materials, and difficulty in coordinating with the rhythm of the next process, seriously affecting the feeding efficiency and leading to low production efficiency.

[0004] Therefore, in view of the above problems, it is urgent to design a feeding device with a vision detection and positioning function to replace traditional manual feeding and meet the requirements of low cost, high precision, and high automation in the workpiece feeding process of the assembly line processing. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a bin-type feeding device with a vision detection function to solve the problems of low feeding efficiency and poor accuracy in the above-mentioned background art. The following technical solutions are provided: A bin-type feeding device with a vision detection function, comprising:

[0006] A frame, inside which a bin lifting mechanism is arranged;

[0007] A motion module, arranged at the upper end of the frame, and the motion module includes a Y-axis module and an X-axis module arranged perpendicular to each other;

[0008] A material picking component, horizontally sliding on the motion module, and a partition picking and placing component is also arranged on one side of the material picking component. The material picking component and the partition picking and placing component are used for picking and placing materials;

[0009] A buffer line, arranged in the middle of the frame, for buffering and placing the workpieces grabbed from the bin lifting mechanism;

[0010] A blanking group, arranged on one side of the frame, and the blanking group is used for evenly picking and placing the workpieces buffered in the buffer line into the processing assembly line.

[0011] The silo lifting mechanism includes vertical plates evenly arranged at two opposite sides of the frame. A first tray and a second tray are vertically slidably arranged in the middle of the vertical plates respectively. The first tray and the second tray are driven by two elevators arranged at the sides of the frame. The motion module includes a Y-axis module and an X-axis module. The Y-axis module is fixedly arranged at the upper end of the frame, and the X-axis module is horizontally slidably arranged in the middle of the Y-axis module. The moving distances of the Y-axis module and the X-axis module are controlled by a PLC respectively.

[0012] In this technical solution, there are two silo lifting mechanisms, which are adjacently arranged at the lower end of the frame. The process of placing the workpiece on the buffer line is as follows: When an operator puts the first tray into the bottom silo, the silo lifting mechanism raises the second tray through the elevator. After passing the position sensor, at this time, the PLC monitors that the silo lifting mechanism stops, and at the same time, the PLC uses the motion module to drive the material taking component to reach above the material. At this time, the light source cooperates with the vision camera to take pictures, and the coordinate data of the workpieces stored in the entire first tray are obtained. At this time, the vision camera sends these coordinate data to the PLC through the intelligent vision system. The PLC sends instructions to the motion control module to drive the motion module to accurately reach above the material. The PLC sends instructions to 3 lifting cylinders to adsorb the workpieces, and the three suction cups suck the three workpieces and transport them to the buffer line.

[0013] In any of the above technical solutions, further, the material taking component includes a mounting plate slidably connected to the X-axis module. A fixed frame is arranged on one side of the mounting plate, and a vision camera and a light source are respectively arranged on the fixed frame. Lifting cylinders are evenly arranged on one side surface of the mounting plate, and a workpiece suction cup is arranged at the lower end of the lifting cylinder. The partition taking and placing component includes a second cylinder fixedly arranged on the other side surface of the mounting plate, and a second suction cup is arranged at the lower end of the second cylinder.

[0014] In this technical solution, the process of discharging materials from the interlayer is as follows: Since the workpieces are stacked on the first tray through the partition layer, when the feeding of the topmost layer of materials on the first tray is completed, the materials need to be taken from the interlayer to carry out the feeding of the next layer of materials. At this time, the PLC sends instructions to drive the motion module to move the truss manipulator (the material taking component and the partition taking and placing component) above the interlayer. At this time, the partition taking and placing component is activated, and the two second suction cups are used to place the partition layer on the second tray of another silo. When both partition layers are taken and placed on the empty tray, the silo lifting mechanism of the silo storing the materials rises one layer, and the silo lifting mechanism storing the partition layer descends a certain distance.

[0015] It should be noted that for the elevator and the motion module in this application, the motion mode can also be driven by means such as air cylinder transmission, screw thread or stepping motor, etc. This application does not make specific limitations on this.

[0016] In any of the above technical solutions, further, the buffer line is fixedly arranged in the middle of the rack, a baffle is arranged at the upper end of the buffer line, and a lens is also arranged at one end of the buffer line. The blanking group includes a blanking cylinder fixedly arranged at one end of the rack, and a blanking suction cup is arranged at the lower end of the blanking cylinder.

[0017] In this technical solution, the process of blanking the workpiece from the buffer line is as follows: when the sensor on the next-process conveyor belt detects that there is no workpiece, it sends a signal to the PLC, and the PLC drives the buffer line to move. At this time, the workpiece is conveyed to one side of the baffle and blocked. Immediately afterwards, the blanking suction cup takes 1 workpiece from the buffer line and places it on the next-process conveyor belt. After the lens detects that the workpiece has been taken away, one more workpiece flows forward to replenish it, and so on for cyclic blanking.

[0018] The beneficial effects of the present utility model are as follows: the lifting of stacked materials is realized through the arranged bin lifting mechanism, and the motion module driven by the PLC drives the vision camera to position the workpieces of the bin lifting mechanism; the position of the workpiece is converted into a digital coordinate, and combined with the workpiece suction cup, rapid loading operation of the workpiece is realized. The vision camera is used to assist the suction cup in loading and unloading the workpiece, expanding the detection range during the loading and unloading of the product, while ensuring the stability during the loading and unloading of the material and the accuracy of the material blanking, thereby solving the problems of low efficiency and poor accuracy in manual loading, and improving the efficiency of the production line.

[0024] Embodiment 1:

[0025] As Figures 1-3 shown, this embodiment provides a bin-type loading device with a visual detection function, including:

[0026] A frame 10, inside which a bin lifting mechanism 20 is provided;

[0027] A motion module 30, arranged at the upper end of the frame 10, the motion module 30 includes a Y-axis module 31 and an X-axis module 32 arranged perpendicular to each other;

[0028] A material taking component 40, horizontally sliding on the motion module 30, and a partition taking and placing component 50 is also provided on one side of the material taking component 40. The material taking component 40 and the partition taking and placing component 50 are used for taking and placing materials;

[0029] A buffer line 60, arranged in the middle of the frame 10, for buffering and placing the workpieces grabbed from the bin lifting mechanism 20;

[0030] A blanking group 70, arranged on one side of the frame 10, the blanking group 70 is used for evenly taking and placing the workpieces buffered in the buffer line 60 into the processing production line.

[0031] The bin lifting mechanism 20 includes vertical plates 21, evenly arranged on two opposite sides of the frame 10. First trays 22 and second trays 23 are respectively vertically slidably arranged in the middle of the vertical plates 21. The first trays 22 and the second trays 23 are driven by two elevators 24 arranged on the sides of the frame 10. The motion module 30 includes a Y-axis module 31 and an X-axis module 32. The Y-axis module 31 is fixedly arranged at the upper end of the frame 10, and the X-axis module 32 is horizontally slidably arranged in the middle of the Y-axis module 31. The moving distances of the Y-axis module 31 and the X-axis module 32 are respectively controlled by a PLC.

[0032] In this technical solution, there are two bin lifting mechanisms 20, which are arranged adjacent to each other at the lower end of the frame 10. The process of placing the workpiece on the buffer line is as follows: when an operator places the first tray 22 into the bottom bin, the bin lifting mechanism 20 raises the second tray 23 through the elevator 24. After passing the position of the in-place sensor, the PLC monitors that the bin lifting mechanism 20 stops. At the same time, the PLC uses the motion module 30 to drive the material taking component 40 to reach above the material. At this time, the light source 44 cooperates with the vision camera 43 to take a picture, obtaining the coordinate data of the workpieces stored in the entire first tray 22. At this time, the vision camera 43 sends these coordinate data to the PLC through the intelligent vision system. The PLC sends instructions to the motion control module to drive the motion module 30 to accurately reach above the material, and the PLC sends instructions to the three lifting cylinders 45 to adsorb the workpieces. The three suction cups hold three workpieces and transport them to the buffer line 60.

[0033] In a preferred embodiment of the present utility model:

[0034] As shown in Figure 2, specifically, the material taking component 40 includes a mounting plate 41 slidably connected to the X-axis module 32. A fixing frame 42 is provided on one side of the mounting plate 41. The vision camera 43 and the light source 44 are respectively provided on the fixing frame 42. Lifting cylinders 45 are evenly arranged on one side surface of the mounting plate 41, and a workpiece suction cup 46 is provided at the lower end of the lifting cylinder 45. The partition taking and placing component 50 includes a second cylinder 51 fixedly provided on the other side surface of the mounting plate 41, and a second suction cup 52 is provided at the lower end of the second cylinder 51.

[0035] In this technical solution, the process of discharging the partition layer is as follows: since the workpieces are stacked in the first tray 22 through the partition layer, when the feeding of the uppermost layer of materials in the first tray 22 is completed, the partition layer needs to be taken off layer by layer to perform the feeding of the next layer of materials. At this time, the PLC sends instructions to drive the motion module 30 to move the truss manipulator (the material taking component 40 and the partition taking and placing component 50) above the partition layer. At this time, the partition taking and placing component 50 is activated, and the two second suction cups 52 are used to place the partition layer on the second tray 23 of another bin. When both partition layers are taken and placed on the empty tray, the bin lifting mechanism 20 of the bin storing the materials rises one layer, and the bin lifting mechanism 20 storing the partition layer descends a certain distance.

[0036] It should be noted that for the elevator 24 and the motion module 30 in this application, the motion mode can also be driven by methods such as air cylinder transmission, screw rod, or stepping motor, and no specific limitation is made in this application.

[0037] In a preferred embodiment of the present utility model:

[0038] As shown in Figure 3, specifically, the buffer line 60 is fixedly arranged in the middle of the rack 10, a baffle piece 61 is arranged at the upper end of the buffer line 60, and a lens 62 is also arranged at one end of the buffer line 60. The blanking group 70 includes a blanking cylinder 71 fixedly arranged at one end of the rack 10, and a blanking suction cup 72 is arranged at the lower end of the blanking cylinder 71.

[0039] In this technical solution, the process of blanking from the workpiece buffer line is as follows: when the sensor on the next-process belt line detects that there is no workpiece, it sends a signal to the PLC. The PLC drives the buffer line 60 to move. At this time, the workpiece is conveyed to one side of the baffle piece 61 and is blocked. Immediately afterwards, the blanking suction cup 72 takes 1 workpiece from the buffer line 60 and places it on the next-process belt line. After the lens 62 detects that the workpiece has been taken away, it flows forward to supplement a workpiece. In this way, the blanking is cycled.

[0040] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims.
