Description

Technical Field

[0001] This utility model relates to the field of flip-board devices, and in particular to a flip-board device for PCB board processing. Background Technology

[0002] Utility model patent CN219761467U discloses a PCB board processing flipping machine, including a flipping machine table. A PCB board is placed on top of the flipping machine table, and a flipping frame for storing the PCB board is provided on the flipping machine table. The flipping frame is an H-shaped baffle, and the PCB board is located inside one of the grooves of the flipping frame. In this utility model, when the PCB board is fixed on the flipping frame, the flipping frame is rotated and adjusted in conjunction with a motor unit. After one side of the PCB board is processed, it is not necessary to remove the PCB board from the flipping frame. The motor unit can rotate 180 degrees through the output shaft to pass through the guide plate on the flipping frame to process the other back side of the PCB board. The PCB board inside the flipping frame is firmly fixed on the flipping frame by fastening claws and two sets of protective grooves, which facilitates the adjustment and processing of both sides of the PCB board. At the same time, the PCB board remains stable inside the flipping frame when flipped at any angle, with strong stability.

[0003] However, when in use, the device has low stability after being flipped and lacks limiting. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as low stability after flipping and lack of limiting, and to propose a flipping device for PCB board processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flipping device for PCB board processing includes a base, a bidirectional screw mounted inside the base via bearings, a limiting plate fixedly connected to the top inner side of the base, the limiting plate and the bidirectional screw being rotatably connected, a slide block connected to the outer side of the bidirectional screw via threads, the slide block and the base being slidably connected, a sliding plate fixedly connected to the upper end of the slide block, a flipping mechanism provided on the sliding plate, a clamping seat provided on the flipping mechanism, a plate being slidably connected inside the clamping seat, and a screw being threadedly connected inside the clamping seat, the screw contacting the plate.

[0007] In addition, a slider is fixedly connected to the lower end of the slide plate, and the slider contacts the base. By setting the slider, the friction between the slide plate and the base is reduced.

[0008] Furthermore, the flipping mechanism includes a side plate, with the upper end of the slide plate in contact with the side plate. A support plate is fixedly connected to the upper end of the slide plate, and the support plate and side plate are slidably connected. The side plate is in contact with the clamping seat. A support shaft is mounted inside the side plate via a bearing, and the support shaft is fixedly connected to the clamping seat. A rotating plate is fixedly connected to the end of the support shaft. A pin is slidably connected inside the rotating plate, and the pin is slidably connected to the side plate. A slip ring is fixedly connected to the outside of the pin, and the slip ring is in contact with the side plate. A spring is provided on the outside of the pin. The rotating plate is driven to rotate by the cooperation of the connecting plate and the pin, which in turn causes the support shaft to drive the clamping seat to rotate, thereby allowing the plate to flip. After flipping, the pin can enter the side plate to limit the rotation of the clamping seat. At the same time, the side plate can slide relative to the support plate to avoid interference caused by the rotation of plates that are too wide.

[0009] Furthermore, a guide pin is fixedly connected to the surface of the support plate, and the guide pin is slidably connected to the side plate. The guide pin guides the movement of the side plate.

[0010] Furthermore, a connecting plate is fixedly connected to the end of the pin, and the connecting plate is in contact with the rotating plate. The movement of the pin is controlled by the connecting plate.

[0011] Furthermore, one end of the spring is fixedly connected to the rotating plate, and the other end of the spring is fixedly connected to the slip ring. The spring design facilitates the return of the slip ring to its original position.

[0012] The beneficial effects of this utility model are as follows:

[0013] The connecting plate and the pin work together to drive the rotating plate to rotate, which in turn causes the support shaft to drive the clamp to rotate, allowing the plate to be flipped. After flipping, the pin can enter the side plate to limit the rotation of the clamp. At the same time, the side plate can slide relative to the support plate to avoid interference caused by the rotation of plates that are too wide. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 A flipping device for PCB board processing includes a base 1. A bidirectional screw 2 is mounted inside the base 1 via bearings. A limiting plate 3 is fixedly connected to the top inner side of the base 1. The limiting plate 3 and the bidirectional screw 2 are rotatably connected. A slide block 4 is threadedly connected to the outer side of the bidirectional screw 2. The slide block 4 and the base 1 are slidably connected. A slide plate 5 is fixedly connected to the upper end of the slide block 4. A slider 6 is fixedly connected to the lower end of the slide plate 5. The slider 6 contacts the base 1. By setting the slider 6, the friction between the slide plate 5 and the base 1 is reduced. A flipping mechanism 7 is provided on the slide plate 5. A clamping seat 8 is provided on the flipping mechanism 7. A plate 10 is slidably connected inside the clamping seat 8. A screw 9 is threadedly connected inside the clamping seat 8. The screw 9 contacts the plate 10.

[0021] Reference Figures 1-4The flipping mechanism 7 includes a side plate 71. The upper end of the slide plate 5 contacts the side plate 71. A support plate 72 is fixedly connected to the upper end of the slide plate 5. The support plate 72 and the side plate 71 are slidably connected. A guide pin 73 is fixedly connected to the surface of the support plate 72. The guide pin 73 is slidably connected to the side plate 71. The side plate 71 is in contact with the clamp 8. A support shaft 74 is installed inside the side plate 71 through a bearing. The support shaft 74 is fixedly connected to the clamp 8. A rotating plate 75 is fixedly connected to the end of the support shaft 74. A pin 76 is slidably connected inside the rotating plate 75. The pin 76 is slidably connected to the side plate 71. A connecting plate 77 is fixedly connected to the end of the pin 76. The connecting plate 77 is in contact with the rotating plate 75. 77. Movement control of pin 76: A slip ring 78 is fixedly connected to the outside of pin 76. The slip ring 78 contacts the side plate 71. A spring 79 is provided on the outside of pin 76. One end of the spring 79 is fixedly connected to the rotating plate 75, and the other end of the spring 79 is fixedly connected to the slip ring 78. By providing the spring 79, the slip ring 78 can be easily reset. The rotating plate 75 is driven to rotate by the cooperation of the connecting plate 77 and pin 76, which in turn causes the support shaft 74 to drive the clamp 8 to rotate, thereby allowing the plate 10 to be flipped. After flipping, it can enter the side plate 71 through pin 76 to limit the rotation of the clamp 8. At the same time, the side plate 71 can slide relative to the support plate 72 to avoid interference caused by the rotation of the plate 10 which is too wide.

[0022] The specific implementation process of this utility model is as follows: When fixing the plate 10, the double-ended screw 2 is manually rotated. The rotation of the double-ended screw 2 and the sliding block 4 make a threaded movement, which in turn causes the sliding block 4 to move the slide plate 5, which in turn moves the position of the flipping mechanism 7, and then moves the position of the clamp 8, so that the plate 10 can be placed between the two clamps 8. The screw 9 is rotated and makes a threaded movement with the clamp 8, which in turn causes the screw 9 to contact the plate 10, and the screw 9 presses the plate 10 into the clamp 8. When flipping the plate 10, the connecting plate 77 is manually pulled. The connecting plate 77 causes the pin 76 to move, which causes the pin 76 to disengage from the side plate 71. The pin 76 causes the slip ring 78 to move, which causes the slip ring 78 to compress the spring 79. Then, through the cooperation of the connecting plate 77 and the pin 76, the rotating plate 75 is controlled to rotate. The rotating plate 75 drives the support shaft 74 to rotate, the support shaft 74 drives the clamp 8 to rotate, and the clamp 8 drives the plate 10 to rotate. 0. During the flipping process, the side plate 71 can be moved upward, allowing it to slide outside the support plate 72. This changes the distance between the rotation axis of the plate 10 and the base 1. The side plate 71 can slide relative to the support plate 72, thus preventing interference caused by the rotation of the excessively wide plate 10. After the plate 10 is flipped, the connecting plate 77 is released, and the spring 79 resets, causing the slip ring 78 to reset. The slip ring 78 then drives the pin 76 to reset, allowing the pin 76 to enter the side plate 71. The connecting plate 77 and the pin 76 work together to rotate the rotating plate 75, which in turn causes the support shaft 74 to rotate the clamp 8. This allows the plate 10 to be flipped. After the flip, the pin 76 can enter the side plate 71 to limit the rotation of the clamp 8. At the same time, the side plate 71 can slide relative to the support plate 72, thus preventing interference caused by the rotation of the excessively wide plate 10.
