Description

Technical Field

[0001] This utility model relates to the technical field of power adapter manufacturing equipment, specifically a PCB cutting device for power adapter manufacturing. Background Technology

[0002] PCB cutting equipment for power adapter manufacturing refers to specialized equipment used in the manufacturing process of power adapters to precisely cut, separate, or trim printed circuit boards (PCBs). The main function of this type of equipment is to safely and efficiently separate multiple small PCB units (usually called "single boards" or "sub boards") from a whole panel, while avoiding damage to circuit components, solder joints, or wiring.

[0003] In existing PCB cutting equipment, when cutting a complete PCB board (i.e., a "positive board") containing chips and wiring breakers, the chip and its associated wiring breaker are usually cut as a single unit. The wiring breaker is designed to ensure the electrical performance, signal integrity, and specification consistency of each chip during manufacturing; it is a functional auxiliary structure. However, because current cutting processes lack the ability to differentiate the connection structure between the chip and the wiring breaker, they are often separated during cutting and fall as a single unit into the subsequent transport system.

[0004] This phenomenon has led to significant subsequent problems: the conveying device cannot distinguish between the chip itself and the associated distribution board, and can only transport both to the next workstation. Therefore, in subsequent processes, operators or automated equipment have to perform additional manual or mechanical sorting, which not only increases labor costs and time consumption, but also may cause chip damage or material mixing risks due to misoperation or identification errors, affecting product yield and production efficiency, and making it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a PCB cutting device for power adapter production, solving the problem mentioned in the background art where the conveying device cannot distinguish between chips and circuit boards, and can only send them together to the next workstation, resulting in the need for additional manual or mechanical sorting. This not only increases costs and time, but also easily causes chip damage or material mixing risks, affecting yield and efficiency, and causing inconvenience in use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PCB cutting device for power adapter production, including a processing table, an auxiliary component on the left side of the processing table, the auxiliary component including a mounting box, a feeding box fixedly connected to the right side of the mounting box, a first motor fixedly connected to the front side of the feeding box, a long rod fixedly connected to the output shaft of the first motor, a push frame installed in the inner cavity of the mounting box, and a top plate fixedly connected to the top of the push frame.

[0007] Furthermore, a rotating rod is provided through the inner cavity of the feeding box, a disc is fixedly connected to the left end of the rotating rod, and a connecting rod is fixedly connected to the left side of the disc.

[0008] Furthermore, a push plate is fixedly connected to the surface of the connecting rod, and a push rod is movably connected to one side of the push plate. The surface of the push rod is movably connected to the inner side of the push frame.

[0009] Furthermore, two meshing bevel gears are fixedly connected to the surfaces of the long rod and the rotating rod, and a first gear is fixedly connected to both the front and rear ends of the long rod. Tooth plates that mesh with the first gear are slidably connected to both the front and rear sides of the feeding box.

[0010] Furthermore, a welding plate is fixedly connected to the surface of the toothed plate, and a pusher plate is fixedly connected to the top of the welding plate.

[0011] Furthermore, a second motor is fixedly connected to the front side of the feeding box, and a short rod is rotatably connected to the front side of the feeding box. The output shaft of the second motor is fixedly connected to the front end of the short rod. Running rods are rotatably connected to both the front and rear sides of the top of the inner cavity of the feeding box.

[0012] Furthermore, the surfaces of the short rod and the adjacent running rod are fixedly connected to each other with two meshing second gears, the surfaces of the short rod and the running rod are equipped with pulleys, and the two pulleys are connected by belt drive. The surfaces of the two running rods are respectively fixedly connected with closing plates.

[0013] Furthermore, sliding rods are fixedly connected to both the front and rear sides of the processing table, and the surfaces of the sliding rods are movably connected to the top plate. A conveying device is installed on the right side of the processing table, and a cutting device and a feeding device are installed on the top of the processing table.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] This invention, through the use of a dedicated auxiliary component, effectively distinguishes and separates scrap boards (i.e., wire separators) from chip boards during PCB board cutting. This auxiliary component, through coordinated actions such as lifting, directional pushing, and material dropping control, immediately diverts or isolates the two types of materials upon completion of cutting, thus avoiding the problem of mixing scrap boards and chip boards and transporting them to the next workstation as in traditional processes. This not only eliminates the subsequent tedious manual or mechanical sorting steps but also significantly reduces the risk of chip damage due to misjudgment, mixing, or improper operation, thereby improving overall production efficiency.

[0027] like Figures 2-6 As shown, a top plate 411 is fixedly connected to the top of the push frame 410. The front side of the top plate 411 has an inclined surface to facilitate the pushing of the PCB board. A rotating rod 45 is provided through the inner cavity of the feeding box 42. The area of ​​the rotating rod 45 in contact with the feeding box 42 is rotatably connected by a bearing. A disc 46 is fixedly connected to the left end of the rotating rod 45. A connecting rod 47 is fixedly connected to the left side of the disc 46. A push plate 48 is fixedly connected to the surface of the connecting rod 47. A push rod 49 is movably connected to one side of the push plate 48. The surface of the push rod 49 is movably connected to the inner side of the push frame 410. Two meshing bevel gears 413 are fixedly connected to the surfaces of the long rod 44 and the rotating rod 45, respectively. A first tooth is fixedly connected to both the front and rear ends of the long rod 44. The wheel 414, the long rod 44 extends to the left and right sides of the feeding box 42 at both ends. The feeding box 42 is slidably connected to the front and rear sides of the feeding box 42, and the toothed plate 415 meshes with the first gear 414. The surface of the toothed plate 415 is fixedly connected to the welding plate 416. The top of the welding plate 416 is fixedly connected to the pusher plate 417. The pusher plate 417 has an inclined surface on one side to facilitate pushing the PCB board. The front side of the feeding box 42 is fixedly connected to the second motor 418. The front side of the feeding box 42 is rotatably connected to the short rod 419. The output shaft of the second motor 418 is fixedly connected to the front end of the short rod 419. The front and rear sides of the top of the inner cavity of the feeding box 42 are rotatably connected to the running rod 420, and the front end of the running rod 420 extends to the front side of the feeding box 42.

[0028] like Figures 3-6As shown, the surfaces of the short rod 419 and the adjacent running rod 420 are fixedly connected to each other by two meshing second gears 421. Pulleys 422 are mounted on the surfaces of the short rod 419 and the running rod 420, and the two pulleys 422 are connected by belt drive. Closing plates 423 are fixedly connected to the surfaces of the two running rods 420, and the two closing plates 423 close together. A partition plate is fixedly connected to the inner cavity of the discharge box 42, and the partition plate is installed above the long rod 44. A vision sensor is installed on the surface of the discharge box 42 to identify waste plates. Slide rods 412 are fixedly connected to both the front and rear sides of the processing table 1, and the surfaces of the slide rods 412 are movably connected to the top plate 411. A conveying device 2 is installed on the right side of the processing table 1, and a cutting device 3 is installed on the top of the processing table 1. The feeding device 5 includes a pusher plate, a first electric guide rail, a mounting plate, a displacement sensor, a cylinder, and a pressure plate. The cutting device 3 includes a second electric guide rail, a mounting block, a stepper motor mounting box, a stepper motor, and a cutting blade. The movable part at the top of the first electric guide rail is pushed into the pusher groove opened inside the mounting plate, thereby pushing the PCB board towards the cutting blade. Then, the cylinder is activated, and the cylinder moves the pressure plate downward, thereby pressing and limiting the PCB board. At this time, the stepper motor and the cutting blade are activated to cut the sub-board in the PCB board assembly process. During the cutting process, the stepper motor and the cutting blade can be activated to rotate, and then the second electric guide rail is activated to drive the cutting blade to move laterally, thereby cutting the sub-board laterally.

[0029] Specifically, the PCB board is first placed on the feeding device 5, and then pushed by the feeding device 5 to the processing position of the cutting device 3. At this time, the cutting device 3 is started to cut the wiring board, i.e. the waste board, on the PCB board. The cutting process is divided into two stages: first, the wiring board is cut; then, the chip board falls to the top of the feeding box 42 under the action of gravity.

[0030] During the cutting process, the first motor 43 is started synchronously, driving the long rod 44 to rotate; the long rod 44 drives the bevel gear 413 to rotate, which in turn drives the rotating rod 45 to rotate; the rotating rod 45 drives the disc 46 to rotate, and the disc 46 pushes the push plate 48 to move through the connecting rod 47; the push plate 48 further pushes the push rod 49 to move, and the push rod 49 pushes the top plate 411 to move upward. Thus, the top plate 411 lifts the dividing plate from below, while simultaneously, in conjunction with the cylinder and pressure plate in the feeding device 5, it limits and presses down on the dividing plate to ensure its stability during the cutting process. In this state, the cutting device 3 precisely cuts the waste portion.

[0031] When the scrap plate is cut off and falls above the discharge box 42 for the first time, the long rod 44 continues to rotate and drives the first gear 414 to rotate synchronously; the first gear 414 meshes and pushes the toothed plate 415 to move horizontally, and the toothed plate 415 drives the welding plate 416 to move synchronously; the welding plate 416 further pushes the pusher plate 417 to move towards the closing plate 423.

[0032] At the same time, the second motor 418 is started, which drives the short rod 419 to rotate. The short rod 419 drives the second gear 421 and the pulley 422 to rotate synchronously. The second gear 421 and the pulley 422 together drive the running rod 420 to rotate. The running rod 420 then drives the closing plate 423 to flip downward, thereby opening the material discharge channel and allowing the waste plate to fall smoothly into the inner cavity of the discharge box 42 for centralized storage.

[0033] After cutting, the PCB chip board is pushed to the conveyor 2 by the pusher plate 417, and then the conveyor 2 stably transports it to the next processing step, realizing efficient and continuous operation, which is convenient for subsequent processing and use.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
