Description

Technical Field

[0001] This utility model relates to the field of PCB depaneling machine technology, and more specifically, to a PCB depaneling component conveying mechanism. Background Technology

[0002] Printed Circuit Board (PCB) serves as a support for electronic components and plays an important role in various industries. At the same time, the continuous advancement of electronic information technology has placed higher demands on the performance of PCBs.

[0003] A PCB board consists of a core board and PP (prepreg) filler. Both surfaces of the core board are covered with copper foil as conductive layers. The PP filler, composed of semi-solid resin and glass fiber, has no copper foil and primarily serves as a filler to bond the core board. Signal vias in a PCB connect transmission lines on different layers. Via stubs are the unused portions of vias that can cause signal reflection, scattering, and delay. Therefore, the PCB needs to be designed for drilling, using a larger diameter drill bit on smaller diameter vias to remove the stubs and reduce signal loss.

[0004] In addition, during the production of a complete PCB board, multiple smaller modules can be designed on the board according to the size of the circuit components, and then these modules can be cut off from the board for use.

[0005] Therefore, equipment such as PCB splitting machines are needed to perform drilling and splitting of PCB boards.

[0006] Existing PCB splitting machines, such as the one described in patent document CN202021434195.8 entitled "A Dual-Station PCB Splitting Machine," include a frame with a worktable and a gantry frame above the worktable; a lateral movement mechanism comprising a first and a second lateral movement module; a longitudinal movement mechanism comprising two sets of longitudinal movement modules mounted on the worktable, each moving a tray on the worktable; a transport mechanism comprising a slide block slidably connected to the first lateral movement module and a gripping component mounted on the slide block, the gripping component being located above the tray; a cutting mechanism comprising a mounting base and a milling cutter mounted on the mounting base, the mounting base being mounted on the second lateral movement module; and a recycling mechanism comprising a connecting slide rail and a waste bin, the slide rail being mounted on the worktable and below the transport mechanism, the waste bin being mounted on the frame.

[0007] Although the aforementioned depaneling machines are equipped with automated feeding and unloading mechanisms, their gripping components can only directly pick up circuit boards with a relatively large area. When the cut circuit boards are used for products with extremely small size requirements, such as wristbands and TWS earphones, their area may be even smaller than the diameter of the suction cups on the gripping components, making it impossible to grip them with suction cups. They are also prone to being lost during transportation after being sent out of the equipment. In view of this, it is necessary to develop component structures that support the picking, placing, and transporting of micro-circuits on depaneling machines. Utility Model Content

[0008] To address the problem that existing circuit board depaneling machine conveying mechanisms cannot properly grasp and transport the tiny circuit board products after depaneling and cutting, thus failing to meet the miniaturization production needs of wearable electronic products, a depaneling component conveying mechanism is provided.

[0009] The board separation component conveying mechanism includes a composite gripper and a product fixture. The composite gripper includes a multi-axis slide table. The circuit board gripper and the fixture gripper are vertically mounted on the multi-axis slide table via a support frame. The fixture gripper includes a left-right symmetrical telescopic driver. The telescopic driver is connected to a gripper component. The product fixture is provided with a circuit board slot.

[0010] Furthermore, the gripper has a locking groove on its bottom inner side, and the product fixture has mating grooves on both sides corresponding to the locking groove.

[0011] Furthermore, the jig gripper includes a gripper bracket, telescopic actuators are symmetrically arranged at both ends of the gripper bracket, and multiple vertically downward scrap suction cups are connected on the gripper bracket between the telescopic actuators.

[0012] Furthermore, the circuit board gripper and the fixture gripper are respectively connected to the support frame via a lifting servo, and the two lifting servos are arranged side by side.

[0013] Furthermore, a vertically downward distance sensor is installed on the support frame, and the distance sensor is electrically connected to the lifting servo, the multi-axis slide, and the telescopic driver.

[0014] Furthermore, the circuit board clamp includes a quick-change slot, a suction cup mounting plate, and circuit board suction cups. The suction cup mounting plate is detachably sleeved in the quick-change slot, and multiple vertically downward circuit board suction cups are inserted through the suction cup mounting plate.

[0015] Furthermore, multiple pressure plate balance columns are also connected to the suction cup mounting plate, and the bottom of the pressure plate balance columns is at the same horizontal plane as the bottom of the circuit board suction cup.

[0016] Furthermore, the multi-axis slide table includes a translation slide table, a lifting slide table is mounted on the translation slide table, and a support frame is mounted on the lifting slide table.

[0017] The advantages of this utility model are:

[0018] 1. It can handle and transport small circuit board products, enabling the depaneling machine to support the processing and output of micro circuit boards.

[0019] 2. High work efficiency, easy operation, and helps improve product quality. Attached Figure Description

[0026] To address the problem that existing circuit board depaneling machine conveying mechanisms cannot properly grasp and transport the tiny circuit board products after depaneling and cutting, thus failing to meet the miniaturization production needs of wearable electronic products, a depaneling component conveying mechanism is provided.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] It should be noted that the terms such as "inner", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as part of the scope of implementation of this utility model, as stated above.

[0029] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," and "joined" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through specific circumstances.

[0030] like Figures 1 to 3 As shown, this embodiment provides a board component conveying mechanism, including a composite gripper and a product fixture 5. The composite gripper includes a multi-axis slide 1. A circuit board gripper 3 and a fixture gripper 4 are vertically mounted on the multi-axis slide 1 via a support frame 2. The fixture gripper 4 includes left and right symmetrical telescopic drivers 401. A gripper component 402 is connected to the telescopic driver 401. A circuit board slot 501 is provided in the product fixture 5.

[0031] The circuit board gripper 3 is used to place the unprocessed circuit board to be cut into the empty product fixture 5. After the board is cut, the fixture gripper 4 can be used to remove the product fixture 5 containing the cut circuit board products to the next station for processing.

[0032] The gripper 402 has a locking groove 403 on its bottom inner side, and the product fixture 5 has a mating groove 502 on both sides corresponding to the locking groove 403. The design of the locking groove 403 and the mating groove 502 can improve the gripping stability and prevent the fixture gripper 4 from loosening and falling off when gripping the product fixture 5, which would cause the circuit board product to scatter.

[0033] The fixture gripper 4 includes a gripper bracket 404, and telescopic actuators 401 are symmetrically arranged at both ends of the gripper bracket 404. Multiple vertically downward-facing scrap suction cups 6 are connected between the gripper bracket 404 and the telescopic actuators 401. When transporting the cut circuit board product using the fixture, after releasing the gripper 402 and lowering the product fixture 5, the scrap generated during the board cutting can be picked up by the scrap suction cups 6, thereby separating it from the circuit board product.

[0034] The circuit board gripper 3 and the fixture gripper 4 are each connected to the support frame 2 via a lifting servo 7, and the two lifting servos 7 are arranged side by side. The circuit board gripper 3 and the fixture gripper 4 can be raised and lowered independently to improve gripping accuracy.

[0035] A vertically downward distance sensor 8 is mounted on the support frame 2. The distance sensor 8 is electrically connected to the lifting servo 7, the multi-axis slide 1, and the telescopic driver 401. The distance sensor 8 can be a commercially available product (such as the Panasonic HG-C1400 laser displacement sensor) to improve the lifting accuracy of the gripper.

[0036] The circuit board gripper 3 includes a quick-change holder 301, a suction cup mounting plate 302, and circuit board suction cups 303. The suction cup mounting plate 302 is detachably fitted into the quick-change holder 301, and multiple vertically downward-facing circuit board suction cups 303 are threaded through the suction cup mounting plate 302. When switching to a different circuit board specification, only the suction cup mounting plate 302 needs to be removed for replacement; there is no need to adjust the position of each circuit board suction cup 303 individually, resulting in high switching efficiency.

[0037] The suction cup mounting plate 302 is also connected to multiple pressure plate balance columns 9, the bottom of which is at the same level as the bottom of the circuit board suction cup 303. Since the circuit board is generally made of composite material and is prone to warping, the pressure plate balance columns 9 are used to flatten the circuit board, ensuring that the circuit board suction cup 303 can stably pick up the circuit board.

[0038] The multi-axis slide 1 includes a translation slide 101, on which a lifting slide 102 is mounted, and a support frame 2 is mounted on the lifting slide 102. The multi-axis slide 1 is a commonly used displacement mechanism on the market, which can ensure the operational stability of the gripper.

[0039] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be assumed that the specific implementation of the present utility model is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present utility model.
