Description

Technical Field

[0001] The utility model relates to the technical field of automated production equipment, in particular to a plate placing machine. Background Art

[0002] As we all know, in automated production, especially for electronic products with many parts, parts are usually imported in batches during batch manufacturing. However, after the parts are imported in batches, there are usually phenomena such as stacking and disordered directions. In order to meet the subsequent parts assembly work, it is necessary to arrange the parts on a tray so that the parts can be arranged in an orderly manner.

[0003] At present, the main structure of the existing tray placing machine is a material tray for pouring parts, a manipulator for grabbing parts, a placing tray for receiving parts and a transmission mechanism for transmitting the placing tray. The material tray has vibration, which can vibrate the stacked parts apart. After image recognition by the camera, the manipulator corrects the direction one by one and places them on the placing tray in an orderly manner. Among them, when the placing tray is full of parts, it is necessary to manually put a new placing tray on the transmission mechanism, and the placing tray full of parts is discharged by the transmission mechanism. However, this type of transmission mechanism can only place placing trays of the same thickness and width, and cannot be adapted to placing trays of different sizes. It also requires manual labor to put the placing trays side by side from time to time. This not only takes up manpower, but is not automated enough on the other hand, so the existing placing machines need to be improved. Utility Model Content

[0022] like Figures 1 to 6As shown, a plate placing machine provided in this embodiment comprises a machine body 1, on which a feed hopper 2, a vibrating feeding tray 3, a vibrating material tray 4, a manipulator 5, a camera 6, a transmission mechanism 7 and a host (not shown in the figure) for controlling the orderly operation of the whole are installed, the feed hopper 2, the vibrating feeding tray 3 and the vibrating material tray 4 are successively connected end to end and arranged in a stepped shape, the camera 6 and the manipulator 5 are located above the vibrating material tray 4, the transmission mechanism 7 comprises a base 71 arranged on the side of the vibrating material tray 4, and the side of the base 71 close to the vibrating material tray 4 is provided with a first A fixing plate 72 is provided, and a second fixing plate 73 is provided at a symmetrical position of the base 71 relative to the first fixing plate 72. At least two guide pillars 74 are provided between the first fixing plate 72 and the second fixing plate 73. A slider 75 that can move back and forth along the guide pillar 74 is installed on the guide pillar 74. A first screw rod 76 is installed on the second fixing plate 73 through a bearing. One end of the first screw rod 76 is placed on the outer side of the second fixing plate 73 and is provided with a crank 77 for the user to rotate and operate. The other end of the first screw rod 76 passes through the slider 75, and the first screw rod 76 and the slider 75 are connected by a The nut sleeve forms a connection, and a movable plate 78 is provided at the upper end of the slider 75. The inner sides of the movable plate 78 and the first fixed plate 72 are provided with sliding grooves 79 that are parallel to each other and meet the placement of the placement plate 100. The base 71 is provided with a servo linear slide 701 at a position between the first fixed plate 72 and the movable plate 78. At least one push block 703 is hingedly installed on the movable seat 702 of the servo linear slide 701. One end of the push block 703 is higher than the movable seat 702 and forms a push head. The other end of the push block 703 is connected to the movable seat 702 through a tension spring 704. The first fixed plate 72 and the movable plate 78 are located on the same side and are both locked with mutually symmetrical baffles 705 by bolts. The holes 706 for passing bolts on the baffle 705 or the first fixed plate 72 and the movable plate 78 are long holes. The slide slot opening 79 is provided with a notch 707 whose length is greater than or equal to the length of the display plate 100 relative to the baffle 705. A bending portion 708 is formed at one end of the baffle 705, and the lower end of the bending portion 708 is placed in the notch 707, and a gap h is reserved from the bottom end of the bending portion 708 to the bottom end surface of the slide slot opening 79 for allowing only a single display plate 100 to pass through.

[0023] This embodiment mainly utilizes the distance between the movable plate 78 and the first fixed plate 72 to increase or decrease the distance between the two slide slots 79, so as to adapt to the placement plates 100 with different widths. At the same time, the design of the long hole 706 of the baffle 705 allows the distance between the bottom end of the bent portion 708 and the bottom end surface of the slide slot 79 to be adjusted by adjusting the height of the bolt installation, so as to adapt to the placement plates with different thicknesses. In this way, the use of placement plates 100 of various specifications can be met, making the equipment more flexible to use.

[0024] During specific operation, the baffle 705 constitutes a storage bin for storing the placing trays 100. Sufficient placing trays 100 are placed in the storage bin. After the storage is completed, the parts that need to be placed on the trays are discharged from the feeding funnel 2. After being poured from the feeding funnel 2, they will directly fall into the vibrating feeding tray 3. The vibrating feeding tray 3 is a conventional component. The parts are gradually pushed and dropped into the vibrating material tray 3 through centrifugal vibration. After the vibrating material tray 3 receives the parts, it does not vibrate all the time. It relies on the recognition result of the camera 6 above to perform corresponding work, that is, the camera 6 will perform image recognition. When the vibrating material tray 3 vibrates once, the camera 6 will identify it. During the identification, if it is found that there is a graspable target, that is, the parts are placed flat, the robot 5 will pick up these parts that can be placed on the tray. When it is found that there are no parts that can be placed, the vibrating material tray 4 will vibrate to disperse the parts stacked together, and then the robot 5 will pick them up. At the same time, because the storage bin formed by the baffle 705 is a plurality of placement trays 100 stacked together, and the notch 707 of the slide slot 79 allows the placement tray 100 at the bottom layer to be placed in the slide slot 79, and under the design of the bent portion 708 of the baffle 705, the front exit only allows one placement tray 100 to be pushed out, and under the action of the tension spring 704, the push head of the push block 703 is placed at the commanding height and touches the placement tray 100 at the bottom layer, and under the drive of the servo linear slide rail 701, the swing tray 100 at the bottom layer is pushed out. After being completely pushed out, the pushed placement tray 100 is placed in the slide slot 79, and the next placement tray 100 automatically falls to the bottom layer, that is, the position of the previous placement tray 100. Then the servo linear slide 701 retreats, and after the push head of the push block 703 hits the placement plate 100, it rotates with the hinge point as the rotation fulcrum to achieve the avoidance effect, and at the same time stretches the tension spring 704. After the push block 703 returns to the initial position under the drive of the servo linear slide 701, under the reaction of the tension spring 704, the push block is reset again to the state of preparing to push the next placement plate 100. The movement of the placement plate 100 in the slide slot 79 enables the next placement plate 100 to push against the previous placement plate 100 after it is pushed out. After the placement plate 100 is pushed out, the parts picked up by the robot 5 can be placed one by one to complete the placement work.

[0025] When different specifications need to be placed, the distance between the movable plate 78 and the first fixed plate 72 is changed by manually turning the crank 77 forward and reversely, so as to adapt to the placement plates 100 with different widths. Therefore, in order to keep the distance between the movable plate 78 and the first fixed plate 72 stable during rotation or after the rotation stops, the guide column 74 of this embodiment is provided with a spring 709, and the spring 709 always keeps in contact with the slider 75. In this way, the structure adjusted by the screw rod can avoid automatic loosening.

[0026] Furthermore, in order to facilitate the push block 703 to move more smoothly after retreating, the push head of the push block 703 of this embodiment is arc-shaped, so that when the push block is avoiding, it can play a certain guiding role and avoid the occurrence of jamming.

[0027] Furthermore, the manipulator 5 of the present embodiment can adopt a variety of structures, and a spider-type manipulator is preferably adopted. The specific structure includes a vacuum suction nozzle 51, a vacuum suction nozzle mounting seat 52 and at least three mounting plates 53 fixedly mounted on the body 1, and a servo motor 54 is arranged on each of the mounting plates 53. The rotating head of the servo motor 54 is connected to a cantilever 55, and a first rotating shaft 56 that can rotate is arranged at the end of the cantilever 55. Both ends of the first rotating shaft 56 are arranged outside the cantilever 55 and are hingedly connected to a connecting rod 57. The vacuum suction nozzle 51 is installed in the middle of the vacuum suction nozzle mounting seat 52, and the pointed mouth of the vacuum suction nozzle 51 is placed at the lower end of the vacuum suction nozzle mounting seat 52. Second rotating shafts 58 corresponding to the number of mounting plates 53 are arranged around the vacuum suction nozzle mounting seat 52, and the two ends of the second rotating shaft 58 are respectively hingedly connected to the corresponding connecting rods 57.

[0028] Furthermore, in order to facilitate the control of the orientation of the movement of the robot 5, the mounting plate 53 of this embodiment is provided with a photoelectric switch 59 at the rotation path of the cantilever 55, and the corresponding end of the cantilever 55 close to the mounting plate 53 is provided with a trigger sheet 501 adapted to the photoelectric switch 59.

[0029] Furthermore, in order to improve the strength of the cantilever 55 , through holes 502 are evenly distributed on the cantilever 55 of this embodiment.

[0030] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
