Description

Technical Field

[0001] The utility model relates to the technical field of PCB production, in particular to a fist-shaped plate part shunting machine. Background Art

[0002] In the PCB manufacturing process, according to different processes in each step, the PCB board needs to be transported from one device to another. In this process, a board receiving machine is usually required. The function of the board receiving machine is to neatly collect the PCB boards transported out one by one on the previous device, so as to facilitate the transfer of the PCB boards to other devices. During the transfer process, a robot is usually used to drive a gripper to grip the board parts on the loading belt. During the operation of the robot, vibrations will be generated, which will affect the judgment of the position of the board parts on the loading belt by the CCD camera, and further affect the accuracy of the robot driving the gripper to grip the board parts, and easily lead to equipment failures. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a fist-shaped plate part shunting machine, aiming to solve the technical problem that vibrations generated during the operation of the robot in the prior art affect the judgment of the position of the board parts on the loading belt by the CCD camera.

[0004] To achieve the above purpose, an embodiment of the utility model provides a fist-shaped plate part shunting machine, including a frame. A first installation cavity and a second installation cavity are formed inside the frame. An installation frame is provided on the inner top surface of the frame. The installation frame is located between the first installation cavity and the second installation cavity. A parallel robot is provided at the bottom of the installation frame. A gripper is provided at the movable end of the parallel robot. A loading belt is placed in the first installation cavity. A buffer plate is provided at the end of the loading belt. A top frame is provided at the top of the head end of the loading belt. The top frame does not contact the inner wall of the frame. A CCD camera is provided at the bottom of the top frame. An unloading belt and a buffer belt are placed in the second installation cavity. The extending directions of the unloading belt and the buffer belt are perpendicular to the extending direction of the loading belt.

[0005] Preferably, a first opening, a second opening and a third opening are formed on the side surface of the frame. The first opening is communicated with the head end of the loading belt. The second opening is communicated with the end of the buffer plate. The third opening is communicated with the end of the unloading belt.

[0006] Preferably, the end of the buffer plate is inclined downward. A plurality of detectors are provided at the head end of the buffer plate. The arrangement direction of the detectors is perpendicular to the extending direction of the buffer plate.

[0007] Preferably, the unloading belt includes a receiving part and a conveying part. The end of the receiving part is connected to the head end of the conveying part. A supporting roller is provided at the end of the receiving part.

[0008] Preferably, a base is provided below the buffer belt. A lead screw is provided inside the base. The upper and lower ends of the lead screw are rotatably connected to the upper and lower surfaces inside the base. Guide rods are symmetrically arranged on both sides of the lead screw. A guide plate is threadedly connected to the lead screw. The guide plate is slidably connected to the guide rods. Both sides of the guide plate extend outward through the base. A plurality of connecting rods extend downward from the bottom of the buffer belt. The connecting rods are connected to both sides of the guide plate.

[0009] Preferably, a chassis is provided at the bottom of the frame. A plurality of mounting pieces fixed to the chassis are provided at the bottoms of the loading belt, the unloading belt, and the buffer belt.

[0010] Preferably, the loading belt is provided with a transparent conveyor belt, and a light source is provided below the loading belt.

[0011] One or more of the above technical solutions in the fist-shaped plate part shunting machine provided by the embodiment of the present invention at least have one of the following technical effects:

[0012] During use, the plate part is placed into the loading belt. The position of the plate part is photographed and recorded by a CCD camera, and the position information is transmitted to the parallel robot. The parallel robot drives the clamping jaws to clamp and arrange the plate parts on the loading belt on the unloading belt. The number of arranged columns is set according to the size of the plate part. The larger the plate part, the smaller the number of columns. The arrangement direction of the plate parts is the same as the arrangement direction of the loading belt, and then it is transported out through the unloading belt. When the number of plate parts is too large and the clamping jaws are too late to arrange the plate parts on the unloading belt, the excess plate parts enter the buffer belt for buffering. When the unloading belt is transporting the arranged plate parts out, but the clamping jaws still have the ability to clamp the plate parts, the parallel robot clamps the plate parts on the loading belt into the buffer belt. When there are plate parts in the buffer belt, the clamping jaws are preferentially used to clamp the plate parts on the buffer belt to the unloading belt for arrangement. During the process of the parallel robot driving the clamping jaws to move, vibrations will be generated. Since the contact area between the frame and the bottom surface is large, setting the parallel robot in the middle of the inner top surface of the frame can achieve better stability during operation, but there will still be a certain amount of shaking. By setting the top frame not to contact the inner wall of the frame, it can be well ensured that the CCD camera can remain stable, and the position information of the plate parts on the loading belt can be accurately transmitted to the parallel robot to achieve an accurate grasping effect.

[0025] In the embodiments of the present utility model, unless otherwise clearly specified and defined, terms such as "installed", "connected", "connected to", "fixed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0026] In an embodiment of the present utility model, as Figures 1 to 7 shown, a fist-shaped plate part shunting machine is provided, which includes a frame 1. A first installation cavity 11 and a second installation cavity 12 are formed inside the frame 1. An installation frame 13 is provided on the inner top surface of the frame 1. The installation frame 13 is located between the first installation cavity 11 and the second installation cavity 12. A parallel robot 14 is provided at the bottom of the installation frame 13. A clamping jaw 141 is provided at the movable end of the parallel robot 14. A feeding belt 2 is placed in the first installation cavity 11. A buffer plate 21 is provided at the end of the feeding belt 2. A top frame 22 is provided at the top of the head end of the feeding belt 2. The top frame 22 does not contact the inner wall of the frame 1. A CCD camera 23 is provided at the bottom of the top frame 22. An output belt 3 and a buffer belt 4 are placed in the second installation cavity 12. The extending directions of the output belt 3 and the buffer belt 4 are perpendicular to the extending direction of the feeding belt 2.

[0027] Furthermore, a first opening, a second opening, and a third opening are formed on the side surface of the frame 1. The first opening communicates with the head end of the feeding belt 2. The second opening communicates with the end of the buffer plate 21. The third opening communicates with the end of the output belt 3. Specifically, the plate part enters the feeding belt 2 through the first opening. The plate part falling into the buffer plate 21 can be taken out manually through the second opening. The output belt 3 arranged on the output belt 3 is transported outward and transported outward through the third opening.

[0028] Furthermore, the end of the buffer plate 21 slopes downward. A number of detectors 211 are provided at the head end of the buffer plate 21, and the arrangement direction of the detectors 211 is perpendicular to the extension direction of the buffer plate 21. Specifically, a baffle is provided at the end of the buffer plate 21 to prevent the plate from falling. Since plates of different sizes can all be transported through the feeding belt 2, the parallel robot 14 drives the gripper 141 to clamp and place them on the discharging belt 3. When the number of plates is too large for the gripper 141 to arrange the plates on the discharging belt 3 in time, the plates enter the buffer plate 21 through the end of the feeding belt 2, and are detected by the detectors 211 when entering the buffer plate 21, and an alarm is issued to remind the operator, achieving the detection effect for plates of different sizes and avoiding omission.

[0029] Furthermore, the discharging belt 3 includes a receiving part 31 and a conveying part 32. The end of the receiving part 31 is connected to the head end of the conveying part 32, and a roller 33 is provided at the end of the receiving part 31. Specifically, the plate is placed into the feeding belt 2, the CCD camera 23 takes a photo and records the position of the plate, and transmits the position information to the parallel robot 14. The parallel robot 14 drives the gripper 141 to clamp the plate on the feeding belt 2 and arrange it on the receiving part 31. During the arrangement process, the receiving part 31 stops conveying. After the arrangement is completed, the arranged plate is conveyed to the conveying part 32 by the receiving part 31 and sent outwards. When the plate passes between the receiving part 31 and the conveying part 32, the roller 33 plays a role of transitional support to prevent the position of the plate from shifting.

[0030] Furthermore, a base 41 is provided below the buffer belt 4. A lead screw 42 is provided inside the base 41. The upper and lower ends of the lead screw 42 are rotatably connected to the upper and lower inner surfaces of the base 41. Guide rods 420 are symmetrically arranged on both sides of the lead screw 42. A guide plate 421 is threadedly connected to the lead screw 42. The guide plate 421 is slidably connected to the guide rods 420. Both sides of the guide plate 421 extend outwards through the base 41. A number of connecting rods 422 extend downward from the bottom of the buffer belt 4, and the connecting rods 422 are connected to both sides of the guide plate 421. Specifically, by driving the lead screw 42 to rotate through a driving motor, the guide plate 421 can be lifted and lowered inside the base 41, thereby achieving the lifting effect of the buffer belt 4.

[0031] Furthermore, a chassis 15 is provided at the bottom of the frame 1. A number of mounting pieces 151 fixed to the chassis 15 are provided at the bottoms of the feeding belt 2, the discharging belt 3, and the buffer belt 4. Specifically, through the mounting pieces 151, the feeding belt 2, the discharging belt 3, and the buffer belt 4 can be fixed at their positions on the chassis 15, thereby achieving the position fixation inside the frame 1.

[0032] Furthermore, the feeding belt 2 is provided with a transparent conveyor belt, and a light source is provided inside the transparent conveyor belt. Specifically, the two ends of the transparent conveyor belt are driven by driving rollers, and a light source is installed between the upper and lower belt bodies of the transparent conveyor belt. The light source is used to illuminate the transparent conveyor belt upward, and the light passes through the transparent conveyor belt and illuminates the back of the plate to form a square backlight area, which is convenient for the CCD camera 23 to capture the position of the plate. Rollers are also installed between the upper and lower belt bodies of the transparent conveyor belt, and the rollers are arranged on both sides of the light source to prevent the transparent conveyor belt from sagging and rubbing against the light source.

[0033] It should be noted that the clamp 141 is composed of multiple groups of bionic suction cups arranged horizontally, among which several bionic suction cups located in the middle are combined to form a first control area, and several bionic suction cups located on both sides of the first control area are combined to form a second control area. The second control area is provided with a cylinder that can be used to control the lifting and lowering of the bionic suction cups in the area. When the clamp 141 needs to clamp a small panel, the bionic suction cups in the second control area are raised by the cylinder, and the panel is clamped by the suction cups in the first control area; when the clamp 141 needs to clamp a large panel, the bionic suction cups in the second control area are lowered by the cylinder, so that the bionic suction cups in the first control area and the second control area can clamp the panel at the same time, thereby achieving the effect of zone control.

[0034] Working principle: When in use, put the plate into the feeding belt 2, take a picture of the position of the plate through the CCD camera 23, and transmit the position information to the parallel robot 14, and connect any driving claw 141 to clamp the plate on the feeding belt 2 and arrange it on the discharge belt 3. The number of columns is set according to the size of the plate. The larger the plate, the smaller the number of columns. The arrangement direction of the plate is consistent with the arrangement direction of the feeding belt 2, and then it is transported out through the discharge belt 3; when the number of plates is too large and the claw 141 is unable to arrange the plates on the discharge belt 3 in time, the excess plates are cached in the buffer plate 21; when the discharge belt 3 is transporting the arranged plates out, but the claw 141 still has enough power to clamp the plates, The parallel robot 14 adds the panels on the feeding belt 2 to the buffer belt 4. When there are panels in the buffer belt 4, the clamp 141 is used to clamp the panels on the buffer belt 4 and arrange them on the discharge belt 3. Vibration will be generated in the process of the parallel robot 14 driving the clamp 141 to move. Since the contact area between the frame 1 and the bottom surface is large, better stability can be achieved during operation by setting the parallel robot 14 in the middle of the top surface of the frame 1. However, some shaking will still occur. By setting the top frame 22 not to contact the inner wall of the frame 1, it can be well ensured that the CCD camera 23 can remain stable, and the position information of the panels on the feeding belt 2 can be accurately transmitted to the parallel robot 14, so as to achieve accurate grasping effect.

[0035] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
