Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production equipment, in particular to a PCB automatic sorting device. Background Art

[0002] A printed circuit board (PCB) is a board made up of integrated circuits, quartz oscillators, fine-tuning capacitors, and printed circuit boards. It can miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. In electronic devices, it is mainly used to connect various electronic components and serves as a structural support.

[0003] During the production process of circuit boards, it is necessary to sort the main boards, sub-boards (such as cameras, indicator lights, fingerprint sensors, etc.) and fork boards (marked defective boards) of the circuit boards, and it is also necessary to conduct random inspections on the main boards of the circuit boards produced in batches; however, the circuit board sorting equipment in the existing technology generally uses a conveyor belt when transporting the circuit boards. When the circuit boards are transported to the set position, the fork boards and sub-boards are first removed and collected from the main boards by a robot, and then the robot sorts the batches of main boards and the main boards that need to be inspected; since the circuit boards are transported in sequence, the robot needs to first pick up the fork boards and sub-boards, then sort the main boards, and then transport the next circuit board that needs to be sorted, which results in slow circuit board sorting efficiency, and this type of equipment can only perform sorting operations on one type of circuit boards, resulting in poor practicality of the sorting equipment. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic PCB sorting device which improves sorting efficiency and has good versatility and practicality.

[0005] In order to solve the above technical problems, the present invention can be implemented by adopting the following technical solutions:

[0006] A PCB automatic sorting device includes a frame, a feeding mechanism, a sorting mechanism, a fork plate collecting mechanism, a secondary plate collecting mechanism and a main plate collecting mechanism. The feeding mechanism and the sorting mechanism are respectively arranged on the frame, and the sorting mechanism is located above the feeding mechanism. The main plate collecting mechanism is respectively provided on both sides of the feeding mechanism. The fork plate collecting mechanism and the secondary plate collecting mechanism are arranged side by side and are located at the end of the feeding mechanism. The sorting mechanism can move back and forth between the feeding mechanism, the fork plate collecting mechanism, the secondary plate collecting mechanism and the main plate collecting mechanism. Identification mechanisms are provided above and below the feeding mechanism, and the identification mechanisms are used to identify the information of the conveyed PCBs.

The sliding plate is connected to the lower slide rail, and lifting cylinders are arranged on both sides of the sliding plate. The two sides of the lower carrier are respectively connected to the lifting cylinders. The lifting cylinders can drive the lower carrier to lift.

[0009] In one embodiment, both the upper carrier and the lower carrier are provided with identification avoidance holes.

[0010] In one embodiment, the feeding mechanism further includes a transfer platform, and the transfer platform is located at the starting end of the upper platform and the lower platform.

[0011] In one embodiment, the sorting mechanism includes a Y-axis moving module, an X-axis moving module and a sorting head. The Y-axis moving module is mounted on a frame, and the X-axis moving module is connected to the Y-axis moving module. The Y-axis moving module drives the X-axis moving module to move along the Y-axis direction. The sorting head is connected to the X-axis moving module.

The loading and unloading trolleys are used to transport the receiving plastic trays. Beneficial effects

[0015] The utility model discloses an automatic PCB sorting device, in which a feeding mechanism alternately conveys PCBs, and when the PCBs are conveyed, an identification mechanism first performs information identification to determine whether the PCBs have a fork plate and a sub-plate. If it is determined that there is no fork plate and sub-plate, after the PCBs are conveyed to a set position, the sorting mechanism takes out the main board that needs to be inspected and places it on a main board collecting mechanism on one side, and takes out the main board that does not need to be inspected and places it on a main board collecting mechanism on the other side. If it is determined that there is a fork plate and a sub-plate, after the PCBs are conveyed to the set position, the sorting mechanism first removes the fork plate and the sub-plate from the main board and places them on the fork plate collecting mechanism and the sub-plate collecting mechanism, thereby realizing the sorting of the PCBs. The alternating conveying of the feeding mechanism saves conveying time, makes the PCBs faster to sort, and improves the sorting efficiency. At the same time, the identification mechanism first identifies the information of the PCBs to determine whether the PCBs have a fork plate and a sub-plate, and then controls the sorting mechanism to realize the sorting of PCBs of different specifications and models, thereby improving the versatility and practicality of the sorting device.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] See also Figures 1 to 3A PCB automatic sorting device includes a frame 100, a feeding mechanism 200, a sorting mechanism 300, a fork plate collecting mechanism 400, a sub-plate collecting mechanism 500 and a main plate collecting mechanism 600. The feeding mechanism 200 and the sorting mechanism 300 are respectively arranged on the frame 100, and the sorting mechanism 300 is located above the feeding mechanism 200. Main plate collecting mechanisms 600 are respectively provided on both sides of the feeding mechanism 200. The fork plate collecting mechanism 400 and the sub-plate collecting mechanism 500 are arranged side by side and are located at the end of the feeding mechanism 200. The sorting mechanism 300 can travel back and forth between the feeding mechanism 200, the fork plate collecting mechanism 400, the sub-plate collecting mechanism 500 and the main plate collecting mechanism 600, and an identification mechanism 700 is provided above and below the feeding mechanism 200. The identification mechanism 700 is used to identify the information of the conveyed PCB.

[0036] Specifically, in this embodiment, when sorting PCBs, the feeding mechanism 200 alternately conveys the PCBs, thereby increasing the loading speed of the PCBs and further increasing the sorting efficiency of the PCBs. During the PCB conveying process, the identification mechanisms 700 provided below and above the feeding mechanism 200 will identify the information of the PCBs. The lower identification mechanism 700 can be fixed on the rack 100, while the upper identification mechanism 700 can be fixed on the machine cover (not shown in the figure). The information of the conveyed PCBs is identified and read by the identification mechanism 700 to determine whether the conveyed PCB has a sub-board and / or a fork board. At the same time, the identified information can also be used to determine which PCB to be sampled. When the PCB is conveyed to the set position and it is identified that the PCB does not have a sub-board and / or a fork board, the sorting mechanism 300 can, based on the identified information, take the main board of the PCB that needs to be sampled and place it on the main board on one side. The collecting mechanism 600 is used, and the main board of the PCB that does not need to be inspected is taken and placed in the main board collecting mechanism 600 on the other side; if it is identified that the PCB has a fork plate and a sub-plate, similarly, after the PCB is transported to the set position, the sorting mechanism 300 will first remove the fork plate and / or the sub-plate from the main board respectively according to the identified information, and place them in the fork plate collecting mechanism 400 and / or the sub-plate collecting mechanism 500, and then take the main board that needs to be inspected and the main board that does not need to be inspected and place them in the corresponding main board collecting mechanism 600, and finally, realize the automatic sorting of PCBs, and through the alternating transportation of the feeding mechanism 200, the PCB can be sorted faster and the sorting efficiency is improved; at the same time, the information of the PCB is first identified by the identification mechanism 700 to determine whether the PCB has a fork plate and a sub-plate, and then the sorting mechanism 300 is controlled to realize the sorting of PCBs of different specifications and models, so as to improve the versatility and practicality of the sorting equipment.

[0037] See also Figure 8In order to conveniently and quickly sort the main boards and sub-boards of the PCB, the sub-board collecting mechanism 500 has the same structure as the main board collecting mechanism 600, and respectively includes a loading and unloading trolley 610 and a receiving plastic tray 620. The sorting mechanism 300 places the sub-boards on the receiving plastic tray 620 of the sub-board collecting mechanism 500, and places the main boards that need to be inspected or do not need to be inspected on the receiving plastic tray 620 of the corresponding main board collecting mechanism 600. When the receiving plastic tray 620 is full, the loading and unloading trolley 610 will transport the receiving plastic tray 620 to unload the materials and transport the new receiving plastic tray 620 to load the materials, thereby realizing automatic sorting of the sub-boards and main boards, making the sorting of the main boards and sub-boards of the PCB more convenient and quick, thereby improving the sorting efficiency of the PCB. The structure of the loading and unloading trolley 610 is the existing technology and will not be described in detail here.

[0038] See also Figure 4 and Figure 5 In order to realize alternating feeding of PCBs, the feeding mechanism 200 in this embodiment includes an upper platform 210 and a lower platform 220. An upper slide rail 230 is provided on the top of the upper platform 210, and the upper slide rail 230 is connected to the upper carrier 240. The lower platform 220 is located on the inner side of the upper platform 210 and is lower in height than the upper platform. A lower slide rail 250 is provided on the top of the lower platform 220, and the lower slide rail 250 is connected to the carrier unit 260. The carrier unit 260 includes a sliding plate 261, a lifting cylinder 262 and a lower carrier 263. The sliding plate 261 is connected to the lower slide rail 250, and lifting cylinders 262 are provided on both sides of the sliding plate 261. The two sides of the lower carrier 263 are respectively connected to the lifting cylinders 262. The lifting cylinders 262 can drive the lower carrier 263 to lift.

[0039] When loading the PCB, the preceding station places the PCB on the upper carrier 240 of the upper platform 210, and the upper carrier 240 moves along the upper slide rail 230 and moves to the set position. When the upper carrier 240 is moved to the set position, the sorting mechanism 300 sorts the PCB on the upper carrier 240; when the upper carrier 240 moves with the PCB, the carrier unit 260 of the lower platform 220 moves in the opposite direction along the lower slide rail 250 and moves to the starting position. At this time, the preceding station places the PCB on the carrier unit 260 of the lower platform 220, and this cycle is repeated to realize alternating loading of the upper carrier 240 and the carrier unit 260, so that the PCB does not need to wait during sorting, thereby improving the loading speed of the PCB and improving the sorting efficiency of subsequent PCBs.

[0040] In order to ensure smooth alternating loading of PCBs, the height of the lower platform 220 will be lower than that of the upper platform 210. In order to ensure that the PCBs on the carrier unit 260 can be sorted by the sorting mechanism 300 after being transported to the set position, when the carrier unit 260 is transported to the set position, the lifting cylinder 262 will drive the lower carrier 263 to lift upward. When lifting upward, the lower carrier 263 will move upward with the PCBs, so that the PCBs are raised to the set position and cooperate with the sorting mechanism 300 to ensure the sorting operation of the PCBs on the lower carrier 263, and make the alternating loading of the PCBs on the upper carrier 240 and the lower carrier 263 smoother without causing any obstruction.

[0041] At the same time, in order to increase the loading speed of the PCB, the feeding mechanism 200 also includes a transfer platform 280, and the transfer platform 280 is located at the starting end of the upper platform 210 and the lower platform 220. The PCB board is first placed on the transfer platform 280 by the previous workstation, and then transferred to the upper carrier 240 or the lower carrier 263 by the transfer platform 280, thereby increasing the loading speed of the PCB.

[0042] Furthermore, in this embodiment, since the information of the PCB may be set at the top or the bottom, in order to enable the PCB of the upper carrier 240 and the PCB of the lower carrier 263 to be identified by the identification mechanism 700 during the transportation process, the upper carrier 240 and the lower carrier 263 are both provided with identification avoidance holes 270, and identification mechanisms 700 are provided below and above the feeding mechanism 200. The identification mechanism 700 can identify the bottom information of the PCB of the upper carrier 240 and the bottom information of the PCB of the lower carrier 263 through the identification avoidance holes 270, or directly identify the top information of the PCB of the upper carrier 240 and the top information of the PCB of the lower carrier 263, so as to facilitate subsequent operations and improve the versatility and practicality of the equipment.

[0043] See also Figure 6 In order to sort the main board, sub-board and fork board of the PCB, the sorting mechanism 300 in this embodiment includes a Y-axis moving module 310, an X-axis moving module 320 and a sorting head 330. The Y-axis moving module 310 is mounted on the frame 100, and the X-axis moving module 320 is connected to the Y-axis moving module 310. The Y-axis moving module 310 can drive the X-axis moving module 320 to move along the Y-axis direction. The sorting head 330 is connected to the X-axis moving module 320. The X-axis moving module 320 can drive the sorting head 330 to move along the X-axis direction. ZR two-axis modules 340 are respectively provided on both sides of the sorting head 330, and the ZR two-axis modules 340 are connected to the sorting suction cups 350.

[0044] When the PCB is transported to the set position by the feeding mechanism 200, the Y-axis moving module 310 and the X-axis moving module 320 will drive the sorting machine head 330 to move toward the PCB. After moving to the position matching the PCB, according to the identification information of the PCB, the ZR two-axis module 340 on one side drives the sorting suction cup 350 to absorb the fork plate / sub-plate of the PCB. After absorption, the Y-axis moving module 310 and the X-axis moving module 320 will drive the sorting machine head 330 to move toward the PCB. The head 330 moves to the top of the fork plate collecting mechanism / sub-plate collecting mechanism 500. At this time, the sorting suction cup 350 directly places the sucked fork plate / sub-plate on the fork plate collecting mechanism / sub-plate collecting unit 500. After the fork plate / sub-plate is sucked, the Y-axis moving module 310 and the X-axis moving module 320 will drive the sorting machine head 330 to move to the PCB again, and according to the sampling signal, the ZR two-axis module 340 on one side drives the sorting suction cup 350 to the PCB that needs to be sampled. The PCB motherboard to be inspected is sucked up, and the ZR two-axis module 340 on this side is driven to move along the Y-axis and X-axis directions by the Y-axis moving module 310 and the X-axis moving module 320. Then, the ZR two-axis module 340 drives the sorting sucker 350 to descend and rotate, and the PCB motherboard to be inspected is placed on the motherboard collecting mechanism 600 on the corresponding side; or the ZR two-axis module 340 on the other side drives the sorting sucker 350 to absorb the PCB motherboard that does not need to be inspected, and then ... descend and rotate, and then the ZR two-axis module 340 on the other side drives the sorting sucker 350 to absorb the PCB motherboard that does not need to be inspected. The Y-axis moving module 310 and the X-axis moving module 320 drive the ZR two-axis module 340 on this side to move along the Y-axis and X-axis directions, and then the ZR two-axis module 340 drives the sorting suction cup 350 to move downward and rotate, and the PCB main boards that do not need to be inspected are placed on the main board collection mechanism 600 on the corresponding side. Finally, the fork boards, sub-boards, and main boards of the PCB are sorted. The ZR two-axis module 340 (lifting and rotation) is a conventional technology and will not be described in detail here.

[0045] In addition, in this embodiment, multiple PCBs can be set on the upper carrier 240 and the lower carrier 263 according to the structure of the upper carrier 240 and the lower carrier 263. In order to improve the sorting of PCBs, in this embodiment, several groups of ZR two-axis modules 340 are respectively provided on both sides of the sorting head 330. Through multiple groups of ZR two-axis modules 340 and corresponding sorting suction cups 350, the fork boards, sub-boards and main boards of multiple PCBs on the upper carrier 240 or the lower carrier 263 can be sorted at the same time, thereby improving the sorting efficiency of PCBs.

[0046] Finally, see Figure 7To facilitate the collection of fork plates, the fork plate collection mechanism 400 in this embodiment includes a collection channel 410 and a collection box 420. The collection channel 410 is mounted on the frame 100, and the collection box 420 is located at the end of the collection channel 410. The bottom of the collection channel 410 is tilted toward the collection box 420. After the sorting mechanism 300 absorbs the fork plates of the PCB, it moves with the fork plates to the top of the collection channel 410 and directly drops the fork plates into the collection channel 410. Since the bottom of the collection channel 410 is tilted, the fork plates slide along the bottom of the collection channel 410 into the collection box 420, thereby collecting the fork plates.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Any person skilled in the art can smoothly implement the present invention according to the drawings and the above description. However, any person skilled in the art who, without departing from the scope of the present invention, makes slight changes, modifications and equivalent changes based on the above disclosed technical content shall be an equivalent embodiment of the present invention. At the same time, any equivalent changes, modifications and equivalent changes made to the above embodiments based on the essential technology of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
