[0001] The invention relates to the technical field of automatic plugging, in particular to automatic circuit board plugging equipment for an inverter production line. Background Art

[0002] An inverter, also known as an inverter power supply, is a power conversion device. An inverter converts DC power into AC power. Generally speaking, an inverter is a device that converts DC power into AC power. A circuit board can be called a printed circuit board or a printed circuit board. Its English name is FPC circuit board. FPC circuit board is also called flexible circuit board. Flexible circuit board is made of polyimide or polyester film as a substrate. It is a highly reliable and highly flexible printed circuit board with high wiring density, light weight, thin thickness and good bending properties. The birth and development of the hard-soft board-FPC and PCB gave birth to a new product, the hard-soft board.

[0018] When it is necessary to adjust the height of the production line transmission belt 41 for conveying workpieces, external force is used to pull the layer plate 3 upward to move, and the layer plate 3 drives the pressure cylinder 24 to move, and the pressure cylinder 24 gradually slides upward along the outer surface of the insertion rod 22, and the ring 23 surrounds the insertion rod 22. When the pressure cylinder 24 is adjusted to a suitable height, the bolt rod 26 is pulled upward, and the bolt rod 26 penetrates into the inner cavity of the insertion rod 22. When the pressure cylinder 24 falls down, it is gradually blocked by the bolt rod 26, thereby ensuring that the height of the equipment is gradually adjusted, improving the purpose of height adjustment, and better and more conveniently meeting people's needs.

[0019] Example 2: Please refer to Figure 1 , Figure 2 , Figure 5-Figure 10 The present invention provides a technical solution: a layer plate 3 is fixedly connected to the top of the lifting device 2, and a conveying device 4 is movably installed in the middle of the inner cavity of the layer plate 3, and the conveying device 4 is used to adjust the conveying state and the plug-in state of the circuit board workpiece; The conveying device 4 includes a transmission belt 41, which gradually drives the arc plate 43 to move synchronously. The thin strips 44 are displaced along with the arc plate 43, and a trend of separating the number of circuit board workpieces is formed between the intervals of the thin strips 44. The arc plate 43 is fixedly installed on the outer surface of the transmission belt 41, and the thin strips 44 are movably installed on the inner side of the top of the arc plate 43. A central axis 45 is rotatably inserted on the inner surface of the transmission belt 41, and a vertical plate 42 is fixedly connected to the top of the central axis 45. An auxiliary device 46 is slidably connected to the outer surface of the arc plate 43.

[0020] The thin strip 44 is embedded in the middle of the top inner part of the arc plate 43. The arc plate 43 is evenly distributed with reference to the center line of the transmission belt 41. The vertical plate 42 is symmetrically designed with respect to the transmission belt 41. The thin strip 44 is made of stainless steel. The auxiliary device 46 also includes a card plate 461. The bottom end of the card plate 461 is movably connected with a vertical frame 462. The bottom end of the vertical frame 462 is movably installed with a spring strip 463. The vertical frame 462 gradually approaches the middle part of the pad 466. The pad 466 limits the vertical frame 462. The baffle 465 firmly supports the top of the card plate 461. The bottom end of the spring strip 463 is fixedly connected with a support strip 464. The end of the support strip 464 away from the spring strip 463 is fixedly connected with a vertical The stand 467 has a pad 466 fixedly mounted on the top of the stand 467, a baffle 465 fixedly connected to the top of the pad 466, a cushion body 469 slidably connected to the front and back inner walls of the correction device 5, a connector 468 fixedly mounted on the side of the cushion body 469 away from the inner wall of the correction device 5, the cushion body 469 is movably plugged into the inner cavity of the cushion body 469, the stand 462 is connected to the support bar 464 through a spring bar 463, the spring bar 463 is evenly distributed with reference to the center line of the support bar 464, the stand 462 is in an arc shape, a notch corresponding to the card plate 461 is provided in the inner cavity of the baffle 465, and the thickness of the support bar 464 is thinner than that of the stand 462.

[0021] When in use, the circuit board to be processed is first placed on the transmission belt 41, and transported to the bottom stand 462 by utilizing the power of the transmission belt 41 when it is powered on. The torsional drive formed by the stand 462 is then used to ensure the balance of the circuit board workpiece insertion and prevent insertion deviation.

[0022] When it is necessary to transport and process the circuit board workpieces, the circuit board workpieces often pile up, and manual selection or straightening is often required, which is inconvenient. Therefore, the servo motor is started, and one side of the motor output end is connected to the central axis 45. The central axis 45 is energized to rotate counterclockwise, and the vertical plate 42 supports the central axis 45. The central axis 45 drives the transmission belt 41 to move, and the transmission belt 41 rotates. The transmission belt 41 gradually drives the arc plate 43 to move synchronously, and the thin strips 44 move with the arc plate 43. The thin strips 44 form a trend of separating the number of circuit board workpieces between each spacing, and the thin strips 44 block the circuit board workpieces placed above the transmission belt 41, thereby ensuring that the circuit board workpieces have the function of rapid transportation, ensuring that the circuit boards are not easily piled up during transportation, and realizing the function of rapid transportation of circuit board workpieces.

[0023] When it is necessary to automatically plug the circuit board workpiece, the circuit board workpiece gradually slides to the inner surface of the card plate 461, and the circuit board workpiece contacts the stand 462. The stand 462 is squeezed by the weight of the circuit board workpiece and moves downward, and the stand 462 pushes the spring bar 463 downward to move. When the stand 462 is squeezed and moves downward, the support bar 464 supports the spring bar 463, and the stand 462 is driven outward at the same time. The stand 462 gradually approaches the middle part of the pad 466, and the pad 466 limits the stand 462. The baffle 465 firmly supports the top of the card plate 461, and the stand 462 is pressed downward. The distance between the spring bar 463 and the connector 468 increases, and the circuit board workpiece moves to the position of the connector 468, and is automatically plugged in through the plug on the top of the connector 468, thereby ensuring the function of fast and automatic plugging and improving the convenience of the equipment.

[0024] Example 3: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: on the basis of embodiment 1, a correction device 5 is movably connected to the outer side of the bottom of the conveying device 4, and the correction device 5 is used to adjust the plug-in balance state of the circuit board workpiece. The connector 468 also includes a fan piece 55, a thin shaft rod 54 is movably inserted in the middle of the bottom end of the fan piece 55, springs are movably installed at the bottom of both ends of the fan piece 55, a card 53 is fixedly connected to the bottom end of the thin shaft rod 54, an anti-detachment layer 56 is fixedly connected to the top of the card 53, a bottom end of the card 53 is fixedly connected to a base plate 52, a shell 51 is fixedly installed on the top of the outer edge of the base plate 52, the inside of the shell 51 is hollow, the card 53 is connected to the fan piece 55 through the thin shaft rod 54, the two sides of the fan piece 55 are gradually balanced, the thin shaft rod 54 supports the fan piece 55, and there is a certain opening distance between the fan piece 55 and the card 53.

[0025] When the position where the circuit board workpiece is automatically plugged in is deflected, the circuit board workpiece gradually moves downward from the outside of the plug-in component 468, and the deflection is corrected by adjusting the balancing force of the fan 55 to complete the anti-plug-in deflection. The circuit board workpiece inside the plug-in component 468 is deflected and enters the cushion body 469. The cushion body 469 is pressed downward, and the cushion body 469 gradually isolates the section in the bottom plate 52 downward, preventing the circuit board workpiece from falling on the bottom plate 52 and being difficult to find, thereby ensuring the accumulation of the circuit board workpiece. When the connector 468 moves downward, the plate at the bottom of the connector 468 squeezes the fan piece 55, and the two sides of the fan piece 55 are gradually balanced. The thin shaft 54 ​​supports the fan piece 55, and the side of the fan piece 55 close to the stand 462 is gradually squeezed downward. When one end is bumpy and tilted, the spring between the fan piece 55 and the card 53 supports and resets it, thereby ensuring that one side of the fan piece 55 is not prone to denting or warping, thereby improving the balance performance of the equipment and reducing the chance of connection errors.
