[0022] Please refer to Figures 1 to 3An embodiment of the present invention provides a docking station mechanism, comprising a mounting base 10 and two vertical plates 20 disposed on the mounting base 10 and arranged opposite to each other on the left and right sides, with a space formed between the two vertical plates 20.

[0023] A plurality of rotating shafts 30 are provided through the vertical plate 20. The plurality of rotating shafts 30 are arranged in sequence from front to back along the length direction of the vertical plate 20 and can rotate relative to the vertical plate 20. Among the plurality of rotating shafts 30, the first rotating shaft 30 corresponds to one end of the vertical plate 20, and the last rotating shaft 30 corresponds to the other end of the vertical plate 20. The number of rotating shafts 30 can be set according to actual conditions. One end of the rotating shaft 30 is located in the space and is fitted with a driving roller 40, which is used to transport PCB boards. The other end of the rotating shaft 30 is located outside the space. The other ends of the plurality of rotating shafts 30 are connected to the transmission assembly 50, which is connected to the drive motor 60. The drive motor 60 is arranged on the side of the vertical plate 20 away from the space through the motor plate 61. The drive motor 60 is used to rotate the multiple rotating shafts 30 through the transmission assembly 50, thereby driving the driving rollers 40 at one end of the multiple rotating shafts 30 to rotate. In actual use, the rotation of the driving rollers 40 at one end of the multiple rotating shafts 30 of the two vertical plates 20 drives the PCB boards located on the driving rollers 40 at one end of the multiple rotating shafts 30 of the two vertical plates 20 to move from front to back, thereby transporting the PCB boards. By using the driving rollers 40 at one end of the multiple rotating shafts 30 of the two vertical plates 20 to transport the PCB boards, since there is no belt, dust loss caused by belt aging is eliminated, thereby preventing contamination of the PCB boards and the production workshop environment. This ensures the cleanliness of the PCB boards and the production workshop, meeting production requirements. In addition, the contact area between the driving rollers 40 and the PCB boards is small, preventing damage to the PCB boards.

[0024] In this embodiment, the vertical plate 20 is provided with a plurality of through holes 21, and a plurality of rotating shafts 30 are respectively provided in the plurality of through holes 21. A first bearing 22 is provided in the through hole 21, and the first bearing 22 is sleeved on the corresponding rotating shaft 30. The first bearing 22 is used to provide rotational support for the corresponding rotating shaft 30.

[0025] The transmission assembly 50 includes a magnetic wheel transmission module and a synchronous belt transmission module. The other ends of the multiple rotating shafts 30 are connected to the magnetic wheel transmission module, and the magnetic wheel transmission module is connected to the drive motor 60 through the synchronous belt transmission module.

[0026] Specifically, the magnetic wheel transmission module includes a transmission shaft 51, a plurality of driving magnetic wheels 52, and a plurality of driven magnetic wheels 53. The transmission shaft 51 is rotatably arranged on the side of the stand plate 20 away from the space through a bearing seat 511. The number of bearing seats 511 can be set according to actual conditions. The plurality of driven magnetic wheels 53 and the plurality of rotating shafts 30 correspond one-to-one. The driven magnetic wheels 53 are sleeved on the other end of the corresponding rotating shafts 30. The plurality of driving magnetic wheels 52 and the plurality of driven magnetic wheels 53 correspond one-to-one. The plurality of driving magnetic wheels 52 are respectively sleeved on the transmission shaft 51 and are respectively located below the corresponding driven magnetic wheels 53.

The driving motor 60 is located below the transmission shaft 51. The synchronous belt transmission module includes a driving synchronous belt wheel 54, a driven synchronous belt wheel 55, and a synchronous belt 56 sleeved on the driving synchronous belt wheel 54 and the driven synchronous belt wheel 55. The driving synchronous belt wheel 54 is sleeved on the output end of the driving motor 60. The driven synchronous belt wheel 55 is sleeved on the transmission shaft 51. The driving motor 60 is used to drive the driving synchronous belt wheel 54 to rotate. Under the action of the driven synchronous belt wheel 55 and the synchronous belt 56, the transmission shaft 51 can be driven to rotate. The rotation of the transmission shaft 51 can drive the plurality of driving magnetic wheels 52 to rotate. By using the principle of mutual action of attractive force and repulsive force between the driving magnetic wheels 52 and the corresponding driven magnetic wheels 53, the corresponding driven magnetic wheels 53 can be driven to rotate by the driving magnetic wheels 52, and the corresponding rotating shafts 30 can be further driven to rotate. The magnetic wheel transmission module is used for transmission, which can realize contactless transmission, has no mechanical wear and noise, and will not produce dust, thereby ensuring the cleanliness of the PCB and the production workshop. Arranging the driving motor 60 below the transmission shaft 51 and connecting the magnetic wheel transmission module and the synchronous belt transmission module can reduce the overall length of the connection table mechanism.

[0027] The side of the stand plate 20 close to the space is rotatably provided with a plurality of passive rollers 70. Each passive roller 70 is located between two adjacent rotating shafts 30.

The first photoelectric sensor 81 is a conventional diffuse reflection type photoelectric switch. The first photoelectric sensor 81 is used to detect the position of the PCB. The bracket 811 provides mounting support for the first photoelectric sensor 81. In actual use, when a PCB board that has completed a previous process moves to a position above the first photoelectric sensor 81, the first photoelectric sensor 81 detects the position of the PCB board. The PCB board is then positioned on the driving roller 40 at one end of the first rotating shafts 30 of the two vertical panels 20. The driving rollers 40 at the ends of the multiple rotating shafts 30 of the two vertical panels 20 then drive the PCB board from front to back.

[0031] In this embodiment, the bracket 811 is L-shaped, including a horizontal portion 8112 and a vertical portion 8111.

The other end of the vertical portion 8111 faces upward and is provided with the first photoelectric sensor 81.

[0032] A second photoelectric sensor 82 is provided within the space. The second photoelectric sensor 82 is located between the last rotating shaft 30 of the two vertical plates 20 and is mounted on a mounting bracket 821. The mounting bracket 821 is mounted on the mounting base 10. The second photoelectric sensor 82 and the mounting bracket 851 are both located below the active roller 40. Both the second photoelectric sensor 82 and the mounting bracket 821 are located near the right vertical plate 20. The second photoelectric sensor 82 is a conventional diffuse reflection type photoelectric switch. The second photoelectric sensor 82 is used to detect the position of the PCB. The mounting bracket 821 provides mounting support for the second photoelectric sensor 82. In actual use, when the PCB moves to a position above the second photoelectric sensor 82, the second photoelectric sensor 82 can detect the position of the PCB.

[0033] In this embodiment, the mounting frame 82 includes a base 8212 and a horizontal plate 8211. The base 8212 is set on the mounting base 10, and the horizontal plate 8211 is arranged horizontally. One end of the horizontal plate 8211 is set at the top of the base 8212, and the other end of the horizontal plate 8211 extends backward. A mounting member 822 is provided on one side of the other end of the horizontal plate 8211, and the second photoelectric sensor 82 is set on the mounting member 822.

[0034] Furthermore, a blocking assembly is provided within the space, located between the last rotating shaft 30 of the two vertical plates 20. The blocking assembly is located between the right vertical plate 20 and the second photoelectric sensor 82. The blocking assembly comprises a drive cylinder 91 and a stopper 92. The drive cylinder 91 is mounted on a mounting frame 821. Specifically, the drive cylinder 91 is attached to the other end of the horizontal plate 8211 via a cylinder plate 911. The stopper 92 is located above the drive cylinder 91 and below the driving roller 40. The stopper 92 is connected to the output end of the drive cylinder 91, and the drive cylinder 91 is used to drive the stopper 92 up and down. In actual use, the drive cylinder 91 first drives the stopper 92 upward, so that the stopper 92 is partially located above the driving roller 40. When the PCB board moves to a position above the second photoelectric sensor 82, the PCB board abuts against the stopper 92, thereby blocking the PCB board and stopping it, facilitating processing in the next step.
