Description

Technical Field

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

[0002] A circuit board is a provider of electrical connections for electronic components. It achieves wiring and electrical connections between electronic components by printing conductive metal lines on an insulating substrate. The substrate is the basic material of a PCB and is usually made of insulating materials such as epoxy resin and fiberglass. It provides a stable plane to support and isolate the circuit.

[0003] A search revealed patent number CN202022546186.4, which discloses a flipping device for PCB circuit board processing. The device includes a processing frame, with a dual-axis motor housing fixedly connected to the center of the bottom of the processing frame's inner cavity. A dual-axis motor is fixedly connected to the inner wall of the dual-axis motor housing. Both output shafts of the dual-axis motor extend to the outside of the processing frame and are fixedly connected to a transmission structure. The transmission structure includes a drive gear fixedly connected to the output shafts of the dual-axis motor. This invention utilizes a stepper motor, which drives a bevel gear to rotate, thereby causing the fixing clamp to move in opposite directions, thus fixing the PCB circuit board. Activating the dual-axis motor drives two drive gears to rotate, ultimately flipping the flat board, achieving high efficiency. This PCB circuit board processing flipping device possesses advantages such as high efficiency, ease of flipping, and good fixation.

[0004] PCB circuit boards are mostly used in industrial or consumer electronics products. The aforementioned patent also has the following problems: before the circuit board is flipped, it needs to be fixed. However, the size and structure of the products are different. Therefore, it is difficult for the same fixing part (flipping part) to accurately clamp circuit boards of multiple specifications. When each type of circuit board is flipped separately, a custom flipping part is required, which increases the processing cost. Utility Model Content

Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0027] See Figures 1-5 This utility model provides a flipping device for PCB circuit board processing, including a support base 1. A motor 2 is connected to one side of the top of the support base 1, and a locking sleeve 3 is provided on the other side of the top of the support base 1. A flipping component 4 is inserted into the locking sleeve 3. The flipping component 4 is connected to the output end of the motor 2. The flipping component 4 includes a flipping plate 6. A fixed arm 8 and a movable arm 9 are respectively provided on both sides of one end of the flipping plate 6. Multiple suction cups 21 are provided at the opposite ends of the fixed arm 8 and the movable arm 9. The multiple suction cups 21 are used to fix the PCB circuit board. As can be seen from the figure, a rod (i.e., a screw) is provided at the tail end of the multiple suction cups 21. The rod is threadedly connected to the fixed arm 8 or the movable arm 9. By rotating the rod, the position of the suction cups 21 can be adjusted to facilitate the subsequent fixing of the circuit board.

[0028] A fine-tuning component is provided on the top side of the flip plate 6. The fine-tuning component is connected to the movable arm 9. The fine-tuning component drives the movable arm 9 to move towards the fixed arm 8.

[0029] A groove 11 is provided at the end of the flip plate 6. A slider 10 is slidably connected in the middle of the groove 11. The length of the groove 11 accounts for one-third of the end of the flip plate 6. Multiple mating holes are pre-set at the end of the slider 10.

[0030] The fine-tuning assembly includes a second slide 18, a second slider 17, and a connecting plate 14. The connecting plate 14 is fixedly connected to the end of the movable arm 9, and the other end of the connecting plate 14 is fixedly connected to the first slider 10. The connecting plate 14 has an inverted L-shaped structure, and the top of the connecting plate 14 protrudes from the top of the flip plate 6.

[0031] The second slide groove 18 is set on the top wall of the flip plate 6. The second slide groove 18 is slidably connected to the second slider 17. The top of the second slider 17 is fixedly connected to the rack 12, and the outer side wall of the rack 12 is fixedly connected to the top of the connecting plate 14.

[0032] Motor 22 is fixedly installed on the side away from slide groove 2 18. The output end of motor 22 is fixedly connected to gear 13. Gear 13 meshes with rack 12. The rotation of gear 13 drives rack 12 to move laterally on slide groove 2 18.

[0033] It should be noted that by starting motor 22, motor 22 drives gear 13 to rotate. Since gear 13 meshes with rack 12, rack 12 completes lateral movement at this time. The bottom of rack 12 slides inside slide groove 18 through slider 2 17. Therefore, slider 10 slides synchronously inside slide groove 11, which can drive the movable arm 9 to move. The maximum range of motion of movable arm 9 is the length range of slide groove 11.

[0034] A connecting rod 7 is fixedly installed at the tail end of the flip plate 6. A plug sleeve 5 is fixedly installed in the middle of the connecting rod 7. The end of the plug sleeve 5 is fixedly connected to the docking rod 16. Multiple through holes are opened on the surface of the docking rod 16.

[0035] Several locking bolts 15 are threadedly connected to the surface of the locking sleeve 3, and the locking bolts 15 are threadedly fixed to the through holes on the surface of the connecting rod 16.

[0036] In use, several locking bolts 15 are inserted into the through holes inside the connecting rod 16 in sequence. The inner wall of the through hole is threaded, and the surface of the locking bolt 15 is provided with a reverse thread opposite to the thread. Therefore, after rotating the locking bolt 15, the two can be locked more firmly, which improves the stability between the locking sleeve 3, the connecting rod 16 and the plug sleeve 5. Later, when the motor 2 drives the flip plate 6 to rotate, it prevents the flip plate 6 from falling off.

[0037] Storage box 20 is fixedly connected to the bottom wall of support base 1. Multiple ventilation openings 19 are fixedly opened on the top wall of storage box 20. Storage box 20 is used to place circuit boards. Storage box 20 is used to place unprocessed PCB circuit boards. At the same time, ventilation openings 19 are provided to facilitate air circulation inside storage box 20.

[0038] By setting a fixed arm 8 and a movable arm 9 at the end of the flipping plate 6, and setting a fine-tuning component on the top wall of the flipping plate 6, the fine-tuning component controls the movement distance of the movable arm 9, thereby adjusting the distance between the movable arm 9 and the fixed arm 8 according to different specifications of circuit boards. The suction cups 21 set on the fixed arm 8 and the movable arm 9 can be fixed to the circuit board, thereby achieving the effect of fine-tuning. It can accurately clamp circuit boards of various specifications and flip them by the drive of motor 1, improving the overall work efficiency and saving subsequent processing costs.
