Description

Technical Field

[0001] This utility model relates to the field of processing auxiliary equipment technology, specifically a processing auxiliary equipment for automatically flipping circuit boards. Background Technology

[0002] A circuit board, also known as a printed circuit board (PCB), is a substrate on which conductive lines are formed through printing, etching, and other processes. It serves to mount and fix electronic components (such as resistors, capacitors, and chips). It provides a platform for electrical connections and mechanical support, allowing components to be connected in an orderly manner according to the designed circuit logic to form a complete electronic circuit system. Its main functions are threefold: first, to achieve electrical connections by connecting different electronic components through conductive lines on the substrate, forming current paths and ensuring normal circuit operation; second, to provide mechanical support by fixing electronic components to the substrate, preventing loosening or displacement, and ensuring the stability of the circuit structure; and third, to simplify circuit layout by rationally designing the routing of lines, reducing the tangled wires, minimizing the size of electronic devices, and facilitating assembly and maintenance. Circuit boards are widely used in almost all electronic equipment fields and are a fundamental component of the electronics industry. In consumer electronics, such as smartphones, computers, tablets, and televisions, circuit boards are core components that support the devices. Circuit boards are essential for the realization of various functions in electronic devices. In the field of communications, base stations, routers, and switches rely on circuit boards for signal transmission and processing. In the automotive electronics field, modules such as in-vehicle navigation, engine control systems, and airbags all rely on circuit boards. Furthermore, circuit boards play a crucial role in industrial control, aerospace, medical equipment, and smart homes, serving as the "skeleton" for the normal operation of various electronic devices. However, traditional circuit board processing auxiliary equipment suffers from several drawbacks. On the one hand, it lacks flexibility in fixing circuit boards, failing to adapt to circuit boards of different sizes and thicknesses. When faced with changes in specifications, it often requires replacing fixing components, resulting in cumbersome operations and poor adaptability, making it difficult to ensure that different circuit boards can be securely fixed. On the other hand, the flipping operation is mostly done manually, which not only increases labor intensity and prolongs processing time but also easily leads to circuit board positioning deviations due to differences in manual operation, affecting the consistency of double-sided processing. Therefore, those skilled in the art provide an automatic circuit board flipping processing auxiliary equipment to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary processing device for automatically flipping circuit boards, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An auxiliary processing device for automatically flipping circuit boards includes a base plate, a flipping structure, a fixing structure, and a second electric push rod. Mounting seats are fixedly connected to the middle of both sides of the base plate, and a first electric push rod is fixedly connected to the top of each mounting seat. A second connecting plate is fixedly connected to the top of the first electric push rod on one side, and a first connecting plate is fixedly connected to the top of the first electric push rod on the other side. A flipping structure is fixedly connected to the second connecting plate, and a fixing structure is fixedly connected to both the flipping structure and the power output end of the second electric push rod.

[0006] As a further embodiment of this utility model: the flipping structure includes a first motor, a rotating shaft and a fixed shaft. The power output shaft of the first motor is fixedly connected to the rotating shaft. The rotating shaft passes through one side of the second connecting plate away from the first motor and is fixedly connected to the fixed shaft. The rotating shaft is rotatably connected to the second connecting plate.

[0007] As a further embodiment of this utility model: the fixing structure includes a fixing plate, a sliding groove, a groove, a second motor, a bidirectional lead screw, a movable frame, a fixing clamp, a rubber pad, and a sliding rod. Two sliding grooves are opened on one side of the fixing plate. A bidirectional lead screw is rotatably connected in one sliding groove, and a sliding rod is fixedly connected in the other sliding groove.

[0008] As a further improvement of this utility model: grooves are provided at the top and bottom of the fixing plate, and the top of the bidirectional lead screw passes through one side of the fixing plate and is fixedly connected to the power output shaft of the second motor.

[0009] As a further improvement of this utility model: the two-way lead screw and slide rod are respectively connected by thread and by sliding connection to two movable frames, and the two corresponding movable frames are fixedly connected by a fixed clamp, and a rubber pad is fixedly connected to one side of the fixed clamp.

[0010] As a further improvement of this utility model, the fixed shaft on the flipping structure is fixedly connected to the fixed plate on the corresponding fixed structure on the side away from the rotation axis.

[0011] As a further embodiment of this utility model: a circular plate is fixedly connected to one side of the first connecting plate, and a connecting shaft is rotatably connected to the side of the circular plate away from the first connecting plate, and the other side of the connecting shaft is fixedly connected to the second electric push rod.

[0012] As a further improvement of this utility model, the power output end of the second electric push rod is fixedly connected to the fixing plate on the corresponding fixing structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In use, first, place the circuit board to be processed stably between the two fixed structures, ensuring that the edge of the circuit board is in the middle of the two fixed clamps, preparing for subsequent fixing. Then, start the second motor in the fixed structure. The power output shaft of the second motor begins to rotate, driving the bidirectional lead screw fixedly connected to it to rotate synchronously in the slide groove on one side of the fixed plate. Because the surface of the bidirectional lead screw has bidirectional threads, and one side of the moving frame is threaded to the bidirectional lead screw, while the other side of the moving frame is slidably connected to the slide bar, under the rotation of the bidirectional lead screw, the two moving frames will move closer to each other along the slide groove, thus... The fixed clamps, which are respectively fixed at the bottom of the two moving frames, move closer to the circuit board. As the fixed clamps gradually approach the circuit board, the rubber pad on one side of the fixed clamp will first contact the surface of the circuit board. As the moving frame continues to move, the rubber pad will be slightly squeezed and deformed until it is tightly attached to the surface of the circuit board. At this time, the rubber pad firmly holds the circuit board with its own good elasticity and large friction force. This not only prevents the circuit board from loosening or shifting during subsequent processing and flipping, but also prevents the fixed clamps from directly and rigidly contacting the circuit board, which would cause scratches on the surface of the circuit board or damage to the components, thus achieving a stable fixation of the circuit board.

[0015] 2. If the height of the circuit board needs to be adjusted during processing to adapt to different processing equipment or processes, activate the first electric push rod on the mounting base in the middle of both sides of the base plate. The power output end of the first electric push rod will extend upward, causing the first connecting plate and the second connecting plate at the top to rise synchronously. The flipping structure, fixing structure, and the fixed circuit board connected to the first connecting plate and the second connecting plate will also rise synchronously. The operator can adjust the circuit board to the required processing height by controlling the extension length of the first electric push rod. If it is necessary to lower the height of the circuit board, simply control the power output end of the first electric push rod to retract, which will cause the circuit board to descend synchronously with each connecting structure until the appropriate height is reached.

[0016] 3. When the other side of the circuit board needs to be processed, the first motor in the flipping structure is started. The power output shaft of the first motor starts to rotate and drives the rotating shaft fixedly connected to it to rotate in the second connecting plate. The side of the rotating shaft away from the first motor passes through the second connecting plate and drives the fixed shaft to rotate synchronously. Since the fixed shaft is fixedly connected to the fixed plate on one side of the fixed structure, and the circuit board is clamped by the two fixed structures, the rotation of the fixed shaft will drive the fixed structure connected to it, the circuit board and the fixed structure on the other side to flip together around the axis of the rotating shaft. During the flipping process, the fixed structure on the other side will rotate around the circular plate through the second electric push rod and the connecting shaft to adapt to the flipping action. After the circuit board is flipped to the required processing angle, the first motor is turned off, the rotating shaft stops rotating, and the circuit board is stably stopped at that angle position so that the other side can be processed.

[0017] 4. If fine-tuning of the lateral position of the circuit board is required during processing to ensure the accuracy of the processing position, the second electric push rod can be activated. The power output end of the second electric push rod will extend or retract as needed to fine-tune the lateral position, thereby adapting to circuit boards of different specifications and lengths.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This embodiment provides an auxiliary processing device for automatically flipping circuit boards, including a base plate 1, a flipping structure 5, a fixing structure 6, and a second electric push rod 9. Mounting seats 2 are fixedly connected to the middle of both sides of the base plate 1. First electric push rods 3 are fixedly connected to the top of each mounting seat 2. A second connecting plate 7 is fixedly connected to the top of one first electric push rod 3, and a first connecting plate 4 is fixedly connected to the top of the other first electric push rod 3. The flipping structure 5 is fixedly connected to the second connecting plate 7. Fixing structures 6 are fixedly connected to the power output ends of both the flipping structure 5 and the second electric push rod 9. When the first electric push rods 3 on the mounting seats 2 in the middle of both sides of the base plate 1 are activated, their power output ends extend upwards, causing the first connecting plate 4 and the second connecting plate 7 at the top to rise synchronously. The flipping structure 5, the fixing structure 6, and the fixed circuit board, which are respectively connected to the first connecting plate 4 and the second connecting plate 7, also rise synchronously. The operator can adjust the circuit board to the required processing height by controlling the extension length of the first electric push rod 3. If it is necessary to lower the height of the circuit board, simply control the retraction of the power output end of the first electric push rod 3 to drive the circuit board to descend synchronously with each connecting structure until a suitable height is reached. The fixed shaft 53 on the flipping structure 5 is fixedly connected to the fixed plate 61 on the corresponding fixed structure 6 on the side away from the rotating shaft 52. A circular plate 8 is fixedly connected to one side of the first connecting plate 4, and a connecting shaft 10 is rotatably connected to the side of the circular plate 8 away from the first connecting plate 4. The other side of the connecting shaft 10 is fixedly connected to the second electric push rod 9. The power output end of the second electric push rod 9 is fixedly connected to the fixed plate 61 on the corresponding fixed structure 6. When the second electric push rod 9 is activated, the power output end of the second electric push rod 9 will extend or retract as needed, thereby making fine adjustments to the lateral position to adapt to circuit boards of different specifications and lengths.

[0028] Example 2

[0029] Reference Figure 1-6This embodiment is based on the previous embodiment, but differs in that the flipping structure 5 includes a first motor 51, a rotating shaft 52, and a fixed shaft 53. The power output shaft of the first motor 51 is fixedly connected to the rotating shaft 52. The side of the rotating shaft 52 away from the first motor 51 passes through one side of the second connecting plate 7 and is fixedly connected to the fixed shaft 53. The rotating shaft 52 is rotatably connected to the second connecting plate 7. When the first motor 51 is started, the power output shaft of the first motor 51 begins to rotate, driving the rotating shaft 52 fixedly connected to it to rotate within the second connecting plate 7. The side of the rotating shaft 52 away from the first motor 51 passes through the second connecting plate 7 and drives the fixed shaft 53 to rotate. The shaft 53 rotates synchronously. Since the fixed shaft 53 is fixedly connected to the fixed plate 61 on the fixed structure 6 on one side, and the circuit board is clamped by the two fixed structures 6, the rotation of the fixed shaft 53 will drive the fixed structure 6 connected to it, the circuit board and the fixed structure 6 on the other side to rotate around the axis of the rotating shaft 52. During the rotation process, the fixed structure 6 on the other side will rotate around the circular plate 8 through the second electric push rod 9 and the connecting shaft 10 to adapt to the rotation action. After the circuit board is rotated to the required processing angle, the first motor 51 is turned off, the rotating shaft 52 stops rotating, and the circuit board is stably stopped at the angle position so that the other side can be processed.The fixing structure 6 includes a fixing plate 61, a sliding groove 62, a recess 63, a second motor 64, a bidirectional lead screw 65, a moving frame 66, a fixing clamp 67, a rubber pad 68, and a sliding rod 69. Two sliding grooves 62 are formed on one side of the fixing plate 61. The bidirectional lead screw 65 is rotatably connected to one sliding groove 62, and the sliding rod 69 is fixedly connected to the other sliding groove 62. Recesses 63 are formed at both the top and bottom of the fixing plate 61. The top of the bidirectional lead screw 65 passes through one side of the fixing plate 61 and is fixedly connected to the power output shaft of the second motor 64. Two movable frames 66 are threadedly connected to the bidirectional lead screw 65 and the slide bar 69, respectively, and the two corresponding movable frames 66 are fixedly connected by fixed clamps 67. Rubber pads 68 are fixedly connected to one side of each fixed clamp 67. The circuit board to be processed is placed stably between the two fixed structures 6, ensuring that the edge of the circuit board is in the middle position of the two fixed clamps 67, in preparation for subsequent fixing. Then, the second motor 64 in the fixed structure 6 is started, and the power output shaft of the second motor 64 begins to rotate, driving... The bidirectional lead screw 65, fixedly connected to the fixed plate 61, rotates synchronously within a groove 62 on one side of the fixed plate 61. Because the surface of the bidirectional lead screw 65 is threaded, and one movable frame 66 is threadedly connected to the bidirectional lead screw 65 while the other movable frame 66 is slidably connected to the slide rod 69, the rotation of the bidirectional lead screw 65 causes the two movable frames 66 to move closer together along the groove 62. This, in turn, causes the fixed clamping plates 67, respectively fixed to the bottom of the two movable frames 66, to move closer synchronously. As the fixed clamping plates 67 gradually approach the circuit board, the rubber pad 68 on one side of the fixed clamping plate 67 first contacts the surface of the circuit board. As the movable frames 66 continue to move, the rubber pad 68 is slightly compressed and deformed until it is tightly adhered to the surface of the circuit board. At this point, the rubber pad 68, with its good elasticity and high friction, firmly clamps the circuit board, preventing loosening or displacement of the circuit board during subsequent processing and flipping, and preventing direct rigid contact between the fixed clamping plate 67 and the circuit board, which could cause scratches on the circuit board surface or damage to components. This achieves a stable fixation of the circuit board.
