Description

Technical Field

[0001] This utility model relates to the field of flipping machine technology, specifically a flipping machine for circuit board production. Background Technology

[0002] Flipping machines can quickly flip PCB / PCBA boards 180 degrees online in production lines such as SMT production lines and coating lines that involve double-sided PCB manufacturing processes, enabling reverse operation and avoiding damage to the boards caused by manual flipping. They are suitable for processes such as mounting components on both sides and applying protective coating.

[0003] Circuit boards typically require double-sided processing during production, such as double-sided insertion, surface mounting, coating, and inkjet printing. The function of a flipping machine is to smoothly and accurately flip a circuit board that has been processed on one side by 180 degrees so that the other side can be processed, thereby improving production efficiency and product quality and reducing errors and damage caused by manual flipping. However, currently, flipping machines often have the problem of not being able to adapt to circuit boards of different sizes, and the clamping of circuit boards is also prone to instability.

[0004] In view of this, we propose a flipping machine for circuit board production. Utility Model Content

[0005] The purpose of this utility model is to provide a flipping machine for circuit board production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A circuit board production flipping machine includes an operating table, a bracket fixedly mounted on the top surface of the operating table, and a flipping assembly provided on the operating table, the flipping assembly comprising:

[0008] A hydraulic cylinder is fixedly installed on the top of the operating table. The piston end of the hydraulic cylinder is fixedly connected to one end of a push rod. A slide rail is fixedly installed on the top of the operating table, and a rack is slidably installed inside the slide rail.

[0009] A connecting rod is fixedly installed at one end of the rack, and the other end of the connecting rod is fixedly connected to the other end of the push rod. A rotating shaft is rotatably installed inside the bracket through a bearing component. A gear is fixedly installed at one end of the rotating shaft, and the gear meshes with the rack.

[0010] A rectangular block is fixedly installed on the outside of the rotating shaft. One end of the rectangular block is fixedly installed with one end of a driven rod, and the other end of the driven rod is provided with an electric clamp.

[0011] In a further embodiment, the support is provided in two sets.

[0012] In a further embodiment, a baffle is provided at one end of the slide rail.

[0013] In a further embodiment, the electric clamping device includes a drive assembly and grippers, and the sidewalls of the two sets of grippers are provided with elastic buffer pads to protect the clamped circuit board and prevent damage to the circuit board during the clamping process.

[0014] In a further embodiment, an auxiliary component is provided on the operating table. The auxiliary component includes a pad. The pad is fixedly installed on the top surface of the operating table. A magnetic strip is fixedly installed on the top of the pad. Metal plates are fixedly installed on both ends of the side wall of the electric clamp.

[0015] In a further embodiment, the pads and magnetic strips are provided in two sets, thereby making the electric clamp more stable.

[0016] In a further embodiment, the movement trajectory of the electric clamp intersects with the magnetic strip, thereby causing the metal strip on the electric clamp to adhere to the magnetic strip.

[0017] Compared with the prior art, this utility model provides a flipping machine for circuit board production, which has the following beneficial effects:

[0018] 1. This circuit board production flipping machine is designed to make flipping circuit boards more convenient and adaptable to circuit boards of different sizes. It is equipped with a flipping component. First, the hydraulic cylinder is activated, and then the push rod, slide rail, rack, connecting rod, rotating shaft, gear, rectangular block and driven rod are used to use an electric clamp to match the circuit boards of different sizes. The electric clamp is then flipped from front to back, which solves the problem of switching between front and back of the circuit board during the processing and adapting to circuit boards of different sizes.

[0019] 2. In order to make the circuit board flipping machine more stable when the electric clamping device flips the circuit board, auxiliary components are set up. Pads and magnetic strips are set on both sides of the electric clamping device. When the electric clamping device flips, the metal sheet on its surface will be attracted to the magnetic strip, generating a light attraction force, which stabilizes the electric clamping device and makes it more stable, thus facilitating subsequent processing.

[0029] Please see Figures 1-3 This utility model provides a technical solution:

[0030] A flipping machine for circuit board production includes an operating table 1, with a bracket 2 fixedly installed on the top surface of the operating table 1.

[0031] In one embodiment of this utility model, a flipping assembly 3 is provided on the operating table 1. The flipping assembly 3 includes a hydraulic cylinder 31. The hydraulic cylinder 31 is fixedly installed on the top of the operating table 1. The piston end of the hydraulic cylinder 31 is fixedly connected to one end of the push rod 32. A slide rail 33 is fixedly installed on the top of the operating table 1. A rack 34 is slidably installed inside the slide rail 33. One end of the rack 34 is fixedly installed with one end of the connecting rod 35. The other end of the connecting rod 35 is fixedly connected to the other end of the push rod 32. A rotating shaft 36 is rotatably installed inside the bracket 2 through bearing components. A gear 37 is fixedly installed at one end of the shaft 36, and the gear 37 meshes with the rack 34. A rectangular block 38 is fixedly installed on the outside of the shaft 36. A driven rod 39 is fixedly installed at one end of the rectangular block 38. An electric clamp 310 is provided at the other end of the driven rod 39. The bracket 2 is provided with two sets. A baffle is provided at one end of the slide rail 33. The electric clamp 310 includes a drive assembly and a gripper. At the same time, the side wall of the gripper is provided with an elastic buffer pad to protect the circuit board being clamped and prevent damage to the circuit board during the clamping process.

[0032] In this embodiment, when the hydraulic cylinder 31 is activated, its piston end drives the push rod 32 to move linearly. When the push rod 32 moves under the drive of the hydraulic cylinder 31, it transmits force to the rack 34 through the connecting rod 35, causing the rack 34 to slide within the slide rail 33. When the rack 34 slides within the slide rail 33, the gear 37 meshing with it will rotate accordingly, thereby driving the rotating shaft 36 to rotate synchronously. As the rotating shaft 36 rotates, the rectangular block 38 and the driven rod 39 will also perform circular motion around the axis of the rotating shaft 36, thereby driving the electric clamp 310 to achieve a 180-degree flip. The rotational motion of the motor inside the electric clamp 310 is transmitted through the connecting rod 35. The shaft transmits power to the lead screw, which, with the help of the nut, converts the rotational motion into linear motion, controlling the opening and closing distance and speed of the grippers to position and clamp circuit boards of different sizes. It is important to note that the clamping force of the electric clamp 310 on the circuit board should be controlled within a reasonable range, and the grippers of the electric clamp 310 are equipped with elastic buffer pads on both sides to protect and buffer the circuit board, preventing damage to the circuit board during clamping. After working on one side of the circuit board, when it needs to be flipped, the hydraulic cylinder 31 is controlled, and its piston end drives the push rod 32 to retract, thus completing the flipping.

[0033] In one embodiment of this utility model, an auxiliary component 4 is provided on the operating table 1. The auxiliary component 4 includes a pad 41. The pad 41 is fixedly installed on the top surface of the operating table 1. A magnetic strip 42 is fixedly installed on the top of the pad 41. Metal plates 43 are fixedly installed on both ends of the side wall of the electric clamp 310. Two sets of pads 41 and magnetic strips 42 are provided. The movement trajectory of the electric clamp 310 intersects with the magnetic strip 42.

[0034] In this embodiment, when the driven rod 39 drives the electric clamp 310 to rotate to a horizontal processing position, the pad 41 fixes and supports the bottom of the electric clamp 310, preventing it from becoming unstable due to suspension and affecting subsequent work. After the pad 41 fixes the clamp, a set of metal plates 43 on the electric clamp 310 are aligned with the magnetic strip 42. An attraction force is generated between the metal plates 43 and the magnetic strip 42. Under the action of this attraction force, the electric clamp 310 can maintain a stable position on the pad 41, effectively reducing the shaking caused by the rotation action or external factors. This ensures that the circuit board is stable after rotation, providing convenience for subsequent processing and ensuring the accuracy and quality of processing. At the same time, it should be noted that the attraction force of the magnetic strip 42 on the metal plates 43 should not be too large, but rather play a light attraction role, to prevent the electric clamp 310 from being difficult to rotate due to the strong attraction force between the magnetic strip 42 and the metal plates 43 when the hydraulic cylinder 31 is started.

[0035] All electrical components mentioned in this application are electrically connected to the PLC controller and 220V AC mains power. The PLC controller is a conventional and known device that can control the hydraulic cylinder 31 and the electric clamp 310. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. The supporting structures of the hydraulic drive structure mentioned in this application, such as the hydraulic tank and hydraulic pump, are existing equipment and will not be described in detail here.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
