Description

Technical Field

[0001] This utility model relates to the technical field of PCB board processing equipment, specifically a PCB board flipping machine. Background Technology

[0002] In the PCB manufacturing process, it is often necessary to process both sides of the PCB board, such as soldering, surface mount technology (SMT), and inspection. This requires flipping the PCB board. An existing patent, CN222845955U, describes a PCB board flipping machine, which includes a control cabinet. A worktable is fixedly connected to one side of the control cabinet, and a first support frame is fixedly connected to the top of the worktable. A conveying device is installed on the top of the first support frame. A first slid groove is formed on the top of the worktable, and a second support frame is slidably connected inside the first slid groove. A flipping gripper is installed on one side of the control cabinet. In this PCB board flipping machine, the PCB board is conveyed via the first support frame during processing. After one side of the PCB board is processed, the first support frame conveys the PCB board to the flipping gripper. When a sensor detects the PCB board, the control cabinet controls the flipping gripper to flip the PCB board. After flipping, the PCB board is placed back on the conveying device for the next process. By moving the position of the second support frame, the equipment can be adapted to different PCB board specifications.

[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Existing PCB flipping operations are mostly performed manually, with operators manually flipping the PCB before proceeding to subsequent processes. This method is not only inefficient and cannot meet the needs of large-scale production, but also prone to damaging the PCB due to improper operation during the flipping process, affecting product quality. Therefore, we propose a PCB flipping machine to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a PCB board flipping machine, which solves the problem that existing flipping operations are mostly done manually, with operators manually flipping the PCB board before proceeding to subsequent processes. This method is not only inefficient and cannot meet the needs of large-scale production, but also prone to damage to the PCB board due to improper operation during the flipping process, affecting product quality.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a PCB board processing flipping machine, including a support mechanism, with transverse grooves on both the front and rear sides of the support mechanism, a servo push rod A fixedly connected inside the transverse groove, and a support plate fixedly connected to the right output end of the servo push rod A.

[0012] Preferably, the pad assembly is made of rubber and is used to support the circuit board.

[0013] Beneficial effects

[0014] This utility model provides a PCB board flipping machine. Compared with the prior art, it has the following advantages:

[0015] This PCB board flipping machine automates the PCB board flipping process through the coordinated operation of servo push rod A, lifting push rod, servo motor and clamping push rod. It eliminates the need for operators to manually flip the PCB boards, greatly reducing manual intervention and significantly improving flipping efficiency.

[0024] 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.

[0025] Please see Figures 1-6This utility model provides a technical solution: a PCB board processing flipping machine, including a support mechanism 1, with transverse grooves on both the front and rear sides of the support mechanism 1, a servo push rod A2 fixedly connected inside the transverse groove, and a support plate 201 fixedly connected to the right output end of the servo push rod A2.

[0026] Two guide sliders 2011 are fixedly connected to the outer side of the support plate 201 in opposite directions. A vertical guide rail mechanism 3 is fixedly connected to the top surface of the support plate 201. A longitudinally arranged lifting push rod 301 is fixedly connected inside the guide rail mechanism 3. A movable frame 301 is fixedly connected to the top of the lifting push rod 301.

[0027] By fixing servo push rods A2 in the transverse grooves on both sides of the support mechanism 1, and connecting the support plate 201 to the output end on the right side of the servo push rods A2, the support plate 201 can move stably in the transverse direction, providing a basis for subsequently driving other components to adjust their positions to adapt to PCB board processing.

[0028] See Figures 1-3 A mounting plate 3012 is fixedly connected to the outer side of the movable frame 3011, and a servo motor 3013 is fixedly connected to the outer side of the mounting plate 3012. An output shaft is provided on the side of the servo motor 3013 closest to the mounting plate 3012.

[0029] By fixing a mounting plate 3012 to the outside of the mobile frame 3011 and connecting a servo motor 3013 with an output shaft to the outside of the mounting plate 3012, the servo motor 3013 can be stably installed, and its output shaft can be used as a power output end to provide power for the operation of subsequent components.

[0030] See Figures 2-4 A clamping push rod 3014 is mounted on the output shaft of the servo motor 3013. A clamping assembly 3015 is fixedly connected to the inner side of the clamping push rod 3014. The clamping assembly 3015 has a U-shaped structure.

[0031] By mounting the clamping push rod 3014 on the output shaft of the servo motor 3013 and connecting the U-shaped clamping assembly 3015 inside the clamping push rod 3014, the clamping push rod 3014 can drive the clamping assembly 3015 to move. The U-shaped clamping assembly 3015 can better fit and clamp the PCB board, ensuring the stability of the PCB board during the processing.

[0032] See Figures 5-6 A barrier assembly 101 is fixedly connected to the top surface of the support mechanism 1, and a pad assembly 1011 is fixedly connected to the inner side of the barrier assembly 101. The pad assembly 1011 has four locations.

[0033] By fixing the enclosure assembly 101 to the top surface of the support mechanism 1 and connecting four pad block assemblies 1011 inside the enclosure assembly 101, the enclosure assembly 101 can limit the PCB board and prevent the PCB board from shifting during placement and processing, while the four pad block assemblies 1011 provide stable support points for the PCB board.

[0034] See Figures 1-2 Four pad block assemblies 1011 are fixedly connected to the four corners of the inner wall of the enclosure assembly 101, and a circuit board 1012 is placed on top of the enclosure assembly 101 and the pad block assemblies 1011.

[0035] By fixing the four padding components 1011 to the four corners of the inner wall of the enclosure component 101, and placing the circuit board 1012 on top of the enclosure component 101 and the padding components 1011, the padding components 1011 at the four corners can ensure that the circuit board 1012 is evenly stressed, thus ensuring the stability of the circuit board 1012 when it is placed and preventing damage to the circuit board 1012 due to uneven stress.

[0036] See Figures 3-5 The front and rear sides of the enclosure assembly 101 are provided with longitudinal grooves, which are used for the clamping assembly 3015 to pass through, and the clamping assembly 3015 is used to clamp the limiting circuit board 1012.

[0037] By opening longitudinal slots on the front and rear sides of the enclosure assembly 101, the clamping assembly 3015 can pass through and clamp the limiting circuit board 1012. The longitudinal slots provide a channel for the movement of the clamping assembly 3015, ensuring that the clamping assembly 3015 can smoothly reach the designated position to clamp and limit the circuit board 1012, and further ensuring the stability of the circuit board 1012 during processing.

[0038] See Figures 1-2 The pad assembly 1011 is made of rubber and is used to support the circuit board 1012.

[0039] By using a rubber pad assembly 1011 to support the circuit board 1012, the rubber material has a certain degree of elasticity and softness, which can play a buffering role when supporting the circuit board 1012, avoiding hard contact between the pad assembly 1011 and the circuit board 1012 and causing damage to the circuit board 1012, thus protecting the quality of the circuit board 1012.

[0040] During operation, the circuit board 1012 to be processed is first placed on the top surface of the support mechanism 1 above the enclosure assembly 101 and the pad assembly 1011. The four pad assemblies 1011 are fixed at the four corners of the inner wall of the enclosure assembly 101, which provides stable support for the circuit board 1012. At the same time, the enclosure assembly 101 can prevent the circuit board 1012 from shifting before subsequent operations, thus preparing for the subsequent flipping operation.

[0041] The servo push rod A2, which is fixed inside the transverse grooves on both sides of the support mechanism 1, is activated. The right output end of the servo push rod A2 pushes the support plate 201, which is fixed to it, to move laterally. During this process, the two guide sliders 2011 fixed on the outer side of the support plate 201 slide along the corresponding track on the support mechanism 1 to ensure the stability of the lateral movement of the support plate 201 until the support plate 201 moves to the lateral position corresponding to the circuit board 1012, so as to meet the position requirements of the subsequent clamping assembly 3015 to clamp the circuit board 1012.

[0042] After the horizontal position of the support plate 201 is adjusted, the lifting push rod 301, which is longitudinally arranged inside the vertical structure guide rail mechanism 3 fixed on the top surface of the support plate 201, is activated. The top of the lifting push rod 301 pushes the movable frame 3011, which is fixedly connected to it, to move vertically along the guide rail mechanism 3. The movable frame 3011 drives the mounting plate 3012 fixed on the outside and the servo motor 3013 fixed on the outside of the mounting plate 3012 to move up and down synchronously until the clamping push rod 3014 and the clamping assembly 3015 installed on the output shaft of the servo motor 3013 reach the longitudinal height that is compatible with the circuit board 1012, and the clamping assembly 3015 can be aligned with the longitudinal slots opened on the front and rear sides of the enclosure assembly 101.

[0043] The clamping push rod 3014 is activated, which pushes the U-shaped clamping assembly 3015 fixedly connected to the inside to move. The clamping assembly 3015 passes through the longitudinal grooves on the front and rear sides of the enclosure assembly 101, gradually approaches the circuit board 1012, and finally clamps and limits the circuit board 1012 to ensure that the circuit board 1012 will not loosen or shift during the flipping process.

[0044] After the circuit board 1012 is stably clamped, the servo motor 3013 is started. The output shaft of the servo motor 3013 drives the clamping push rod 3014, the clamping assembly 3015 and the clamped circuit board 1012 to rotate together, realizing the flipping operation of the circuit board 1012. According to the processing requirements, the servo motor 3013 can precisely control the flipping angle to ensure that the circuit board 1012 is flipped to the required processing angle.

[0045] After the circuit board 1012 is flipped, the clamping push rod 3014 is controlled to drive the clamping assembly 3015 to release the circuit board 1012, so that the circuit board 1012 is placed back on the pad assembly 1011; then the lifting push rod 301 is controlled to drive the moving frame 3011, the mounting plate 3012, the servo motor 3013, the clamping push rod 3014 and the clamping assembly 3015 to descend and reset; finally, the servo push rod A2 is controlled to drive the support plate 201 and related components to move laterally and reset, completing one PCB board flipping operation, and waiting for the next flipping operation.

[0046] In summary, the device, by providing pad assembly 1011, can provide flexible support for circuit board 1012.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
