Description

Technical Field

[0001] This utility model relates to the field of circuit board production equipment technology, and more specifically, to a circuit board separation and handling mechanism. Background Technology

[0002] PCB (Printed Circuit Board), also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board.

[0003] After the circuit board is manufactured, multiple modules can be designed on the circuit board according to the customer's requirements. Then these modules are cut off from the circuit board. At this time, equipment such as a board splitter is needed to cut out the shape required by the customer.

[0004] Existing board separation machine solutions are illustrated in patent document CNCN202110711076.5, entitled "Circuit Board Separating Machine and Separating Method." This machine is used to separate circuit boards to be processed. The circuit board to be processed includes a core layer and a substrate located on the surface of the core layer. The board separation machine includes a separation device, which includes a separating blade for completely separating the core layer and the substrate. It also includes a carrier conveyor for transporting and positioning the circuit board to be processed at the separation device. A transfer device, located on the side of the carrier conveyor away from the separation device, is used to transport the circuit board to be processed to the carrier conveyor.

[0005] However, the vacuum chucks on the transfer device of the aforementioned depaneling machine are fixed in position. If the circuit boards to be cut by the depaneling machine are small and fragmented, the vacuum chucks cannot guarantee that all the cut circuit boards can be picked up. Adjusting the position of the vacuum chucks is also cumbersome when switching between different circuit board sizes, resulting in longer downtime and reduced production efficiency. Utility Model Content

[0006] To address the issues faced by conventional PCB depaneling machines on the market, such as the inability of their PCB gripping mechanism to quickly retrieve all PCBs when cutting fragmented products in large quantities, the cumbersome adjustment of the PCB gripping mechanism, and the time-consuming downtime for adjustment when changing PCB production models, a PCB front and rear transport mechanism is provided.

[0007] The circuit board separation front and rear transport mechanism includes a translational lifting platform. A docking frame is installed on the translational lifting platform. A suction cup positioning plate is detachably installed on the docking frame. Multiple product suction cups and scrap suction cups are vertically connected to the suction cup positioning plate. Both product suction cups and scrap suction cups protrude downward from the suction cup positioning plate.

[0008] Furthermore, the translational lifting platform includes a horizontal slide and a lifting slide. A vertical base plate is slidably connected to the horizontal slide, the lifting slide is mounted on the vertical base plate, and the docking frame is slidably connected to the lifting slide.

[0009] Furthermore, a full-size suction cup is provided on the side of the docking frame corresponding to the direction of movement of the horizontal slide, and the full-size suction cup moves synchronously with the docking frame.

[0010] Furthermore, the entire suction cup includes a positioning bracket and multiple adjustable suction nozzles. The positioning bracket is provided with multiple docking holes, and the adjustable suction nozzles can be detachably connected to the docking holes.

[0011] Furthermore, proximity switches are provided on the left and right sides of the horizontal slide and on the upper and lower sides of the lifting slide.

[0012] Furthermore, a lifting driver is provided at the top of the docking frame, and a suction cup positioning plate is provided at the bottom of the docking frame.

[0013] Furthermore, a vertical support is installed on the translational lifting platform, the lifting driver is installed on the vertical support, and a displacement sensor is also vertically downwardly installed on the vertical support, the displacement sensor being electrically connected to the lifting driver.

[0014] Furthermore, both the product suction cup and the scrap suction cup are connected to a vacuum system via air paths. The vacuum system includes a vacuum pump, a solenoid valve, and a vacuum filter connected in sequence.

[0015] The advantages of this utility model are:

[0016] 1. The suction cup positioning plate can be used to set the number and position of multiple suction cups according to the cut circuit board products, so as to ensure that multiple circuit board products can be accurately removed from the depaneling machine.

[0017] 2. The suction cup positioning plate can be quickly replaced, reducing downtime when switching production circuit board models.

[0018] 3. In addition to picking up the product, a suction cup is also provided for picking up scraps, so that the product and scraps can be separated and processed.

[0019] 4. The feeding and unloading processes can be carried out simultaneously, resulting in high work efficiency. Attached Figure Description

[0026] To address the issues faced by conventional PCB depaneling machines on the market, such as the inability of their PCB gripping mechanism to quickly retrieve all PCBs when cutting fragmented products in large quantities, the cumbersome adjustment of the PCB gripping mechanism, and the time-consuming downtime for adjustment when changing PCB production models, a PCB front and rear transport 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.

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.

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 circuit board separation front and rear transport mechanism, including a translational lifting platform 1. A docking frame 2 is installed on the translational lifting platform 1. A suction cup positioning plate 3 is detachably installed on the docking frame 2. Multiple product suction cups 301 and scrap suction cups 302 are vertically connected to the suction cup positioning plate 3. Both the product suction cups 301 and the scrap suction cups 302 protrude downward from the suction cup positioning plate 3.

[0031] The suction cup positioning plate 3 can be made of transparent engineering plastic, allowing staff to easily check the operating status of the suction cups. Holes are drilled in the suction cup positioning plate 3 according to the quantity and location of the circuit board products after cutting, as well as the location of the scrap materials. The product suction cups 301 and scrap suction cups 302 are then inserted into the holes and fixed, quickly completing the position and quantity configuration of the product suction cups 301 and scrap suction cups 302. In this embodiment, the docking frame 2 and the suction cup positioning plate 3 are fixed with bolts, making assembly and disassembly convenient.

[0032] The translational lifting platform 1 includes a horizontal slide 101 and a lifting slide 102. A vertical base plate 103 is slidably connected to the horizontal slide 101, and the lifting slide 102 is mounted on the vertical base plate 103. The docking frame 2 is slidably connected to the lifting slide 102. Linear slides are commonly used components for displacement transportation, have strong load-bearing capacity, and can ensure the accurate movement position of each suction cup.

[0033] A full-size suction cup 4 is provided on the side of the docking frame 2 corresponding to the moving direction of the horizontal slide table 101. The full-size suction cup 4 moves synchronously with the docking frame 2. In order to improve the loading and unloading efficiency, a full-size suction cup 4 is provided on the circuit board handling mechanism for loading uncut circuit boards. When the distance between the full-size suction cup 4 and the suction cup positioning plate 3 is equal to the distance between the loading position and the cutting position, and the distance between the cutting position and the unloading position, when the full-size suction cup 4 picks up the uncut circuit board at the loading position, the product suction cup 301 and the scrap suction cup 302 can simultaneously pick up the circuit board product and the scrap after the cutting position is completed. Then, the translational lifting table 1 drives the full-size suction cup 4 and the suction cup positioning plate 3 to move forward. The full-size suction cup 4 moves to the cutting position, the suction cup positioning plate 3 moves to the unloading position, the uncut circuit board is placed in the cutting position, and the product suction cup 301 and the scrap suction cup 302 are released one by one, so that the circuit board product and the scrap are separated and sent out.

[0034] The entire suction cup 4 includes a positioning bracket 401 and multiple adjustable suction nozzles 402. The positioning bracket 401 is provided with multiple docking holes 403, and the adjustable suction nozzles 402 are all detachably connected to the docking holes 403. The number and position of the adjustable suction nozzles 402 on the entire suction cup 4 can also be configured as needed. Since the accuracy requirements for the number and position of the adjustable suction nozzles 402 are relatively low, in this embodiment, the positioning bracket 401 adopts the same main body design as the docking frame 2, and multiple docking holes 403 are provided on the main body, so that the adjustable suction nozzles 402 can be quickly assembled and fixed.

[0035] Proximity switches 5 are provided on the left and right sides of the horizontal slide 101 and the upper and lower sides of the lifting slide 102. The proximity switches 5 can be commonly used photoelectric sensors (such as BC-SX672) to prevent damage to the equipment caused by excessive operation of the translation and lifting slide 1 and to improve the accuracy of movement and positioning.

[0036] A lifting driver 6 is provided at the top of the docking frame 2, and a suction cup positioning plate 3 is provided at the bottom of the docking frame 2. Since the thickness of the circuit boards varies, the lifting driver 6 is configured to work with the lifting slide 102 to ensure that the suction cup is accurately attached to the surface of the circuit board for suction.

[0037] A vertical support 7 is mounted on the translational lifting platform 1, and the lifting driver 6 is mounted on the vertical support 7. A displacement sensor 8 is also vertically downwardly mounted on the vertical support 7, and the displacement sensor 8 is electrically connected to the lifting driver 6. In this embodiment, the displacement sensor 8 can be a commonly used product on the market (such as Panasonic HG-C1400), while the lifting driver 6 uses a lifting cylinder. This allows the displacement sensor 8 to accurately control the travel of the lifting cylinder, ensuring that the suction cup accurately descends to the surface of the circuit board. It is worth mentioning that in this embodiment, a lifting cylinder is also configured on the entire suction cup 4.

[0038] Both the product suction cup 301 and the scrap material suction cup 302 are connected to a vacuum system via air circuits. The vacuum system includes a vacuum pump (not shown in the figure), a solenoid valve 901, and a vacuum filter 902 connected in sequence. By using an industrial control computer to control the solenoid valve 901, the opening and closing of each suction cup can be accurately controlled, so that the circuit board product and scrap material are released from the suction cups at different times.

[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.
