The receiving platform 50 can receive the PCB board 90 sorted out by the detection track 30.

[0068] For the first conveying path 60, please refer to Figure 2-Figure 4 The first conveyor 60 is installed on the receiving platform 50 and is parallel or colinear with the detection track 30. Along the length direction of the first conveyor 60, the first conveyor 60 is provided with a plurality of first buffer stations 61, and the first buffer stations 61 are used to store the PCB boards 90 that have passed the inspection. Figure 1 As shown, the length direction of the detection track 30 is consistent with the length direction of the first conveyor path 60, and the heights of the two are consistent. When the detection track 30 is flush with the first conveyor path 60, the PCB board 90 can be conveyed to the first conveyor path 60 through the detection track 30.

[0069] In one embodiment, please refer to Figure 4 The first conveying path 60 includes a first track plate 62, a second track plate 63 and a support shaft 64. The first track plate 62 and the second track plate 63 are arranged opposite to each other and are both perpendicular to the upper end surface of the receiving platform 50. The support shaft 64 is connected between the first track plate 62 and the second track plate 63. The first track plate 62 and the second track are connected and fixed by the support shaft 64.

[0070] In one embodiment, a plurality of first buffer stations 61 are aligned and spliced ​​to form a first conveying channel 60. Figure 4 The first conveyor path 60 includes four first cache stations 61, which are arranged along the length direction of the first conveyor path 60, and two adjacent first cache stations 61 are in close contact, so that the PCB board 90 on any first cache station 61 can be transferred to any adjacent first cache station 61.

[0071] In one embodiment, please refer to Figure 5 and Figure 6The first cache station 61 includes: a driving shaft 611, a first driving wheel 612, a second driving wheel 613, a first transmission wheel 614, a second transmission wheel 615, a first belt 616, a second belt 617 and a second driving mechanism 618. The driving shaft 611 is rotatably connected between the first track plate 62 and the second track plate 63. The first track plate 62 is provided with a through shaft hole, and the driving shaft 611 passes through the shaft hole. The first driving wheel 612 is sleeved on the driving shaft 611 and rotatably connected to the end surface of the first track plate 62 facing the second track plate 63. The second driving wheel 613 is sleeved on the driving shaft 611 and rotatably connected to the end surface of the second track plate 63 facing the first track plate 62. It can be understood that the axes of the two driving rollers are both the driving shaft 611. There are two first transmission wheels 614, which are arranged along the length direction of the first track plate 62 and are both rotatably connected to the end surface of the first track plate 62 facing the second track plate 63; there are two second transmission wheels 615, which are arranged along the length direction of the second track plate 63 and are both rotatably connected to the end surface of the second track plate 63 facing the first track plate 62. The first belt 616 is sleeved on the first driving wheel 612 and the two first transmission wheels 614, and the second belt 617 is sleeved on the second driving wheel 613 and the two second transmission wheels 615. The second driving mechanism 618 is connected to the driving shaft 611 in a transmission manner. The second driving mechanism 618 can be selected to be a motor. The motor is installed on the outer surface of the first track plate 62. The output end of the motor is connected to the driving shaft 611 to drive the driving shaft 611 to rotate, which can drive the two driving wheels to rotate. The rotation of the first driving wheel 612 can drive the first belt 616 to transmit on the two first transmission wheels 614. The rotation of the second driving wheel 613 can drive the second belt 617 to transmit on the two second transmission wheels 615, so as to realize the transportation of the PCB board 90 on the first conveying path 60.

[0072] It can be understood that the first transmission wheels 614 of all the first cache stations 61 are flush with each other, and the second transmission wheels 615 of the first cache stations 61 are also flush with each other, so as to ensure smooth transportation of the PCB boards 90 .

[0073] In one embodiment, the first buffer station 61 further includes a first support platform 619 and a second support platform 620. The first support platform 619 is disposed between the two first transmission wheels 614 and fixedly connected to the end surface of the first track plate 62 facing the second track plate 63, and is used to receive the first belt 616; the second support platform 620 is disposed between the two second transmission wheels 615 and fixedly connected to the end surface of the second track plate 63 facing the first track plate 62, and is used to receive the second belt 617.

[0074] like Figure 6As shown, the first support platform 619 can be set to be a long strip, and the upper surface of the first support platform 619 is a plane; the first support platform 619 is set on the inner ring of the first belt 616 and is fixedly connected to the first track plate 62. The connection method can be welding or screw connection, or the first support platform 619 and the first track plate 62 can be integrally formed.

[0075] When there is a PCB board 90 on the first belt 616, the upper surface of the first support platform 619 will fit with the first belt 616, so that the first support platform 619 can support the PCB board 90 to ensure the smooth transportation of the PCB board 90; to ensure the smooth contact between the first belt 616 and the first support platform 619, the two ends of the first support platform 619 can be set as smooth curved surfaces. It can be understood that the second support platform 620 is set on the inner circle of the second belt 617 to support the PCB board 90 on the second belt 617.

[0076] For the second conveying path 70, please refer to Figure 4 The second conveyor path 70 is installed on the receiving platform 50 and is parallel to the first conveyor path 60. Along the length direction of the second conveyor path 70, a plurality of second buffer stations 71 are provided on the second conveyor path 70. The second buffer stations 71 are used to store the PCB boards 90 that fail the inspection.

[0077] Specifically, the second conveying path 70 includes a third rail plate 72; the third rail plate 72 is parallel to the second rail plate 63 and perpendicular to the upper end surface of the receiving platform 50, and the support shaft 64 extends from the third rail plate 72 and is fixedly connected to the third rail plate 72. It can be understood that the first rail plate 62, the second rail plate 63 and the third rail plate 72 are all parallel, flush and equidistantly arranged, the interval between the first rail plate 62 and the second rail plate 63 is the first conveying path 60, and the interval between the third rail plate 72 and the second rail plate 63 is the second conveying path 70.

[0078] Based on the same inventive concept, in one embodiment, a plurality of second buffer stations 71 are aligned and spliced ​​to form a second conveying path 70, see Figure 2 and Figure 4 The second conveyor path 70 includes four second cache stations 71, which are arranged along the length direction of the second conveyor path 70, and two adjacent second cache stations 71 are in close contact, so that the PCB board 90 on any second cache station 71 can be transferred to any adjacent second cache station 71.

[0079] Based on the same inventive concept, in one embodiment, the second cache station 71 includes: a second driving shaft, a third driving wheel, a fourth driving wheel, a third transmission wheel, a fourth transmission wheel, a third belt, a fourth belt and a third driving mechanism.

[0080] The second drive shaft is rotatably connected between the third track plate 72 and the second track plate 63; the third driving wheel is sleeved on the second drive shaft and rotatably connected to the end surface of the third track plate 72 facing the second track plate 63, and the fourth driving wheel is sleeved on the second drive shaft and rotatably connected to the end surface of the second track plate 63 facing the third track plate 72. There are two third transmission wheels, which are arranged along the length direction of the third track plate 72 and are both rotatably connected to the end surface of the third track plate 72 facing the second track plate 63; there are two fourth transmission wheels, which are arranged along the length direction of the second track plate 63 and are both rotatably connected to the end surface of the second track plate 63 facing the third track plate 72. The third belt is sleeved on the third driving wheel and the two third transmission wheels, and the fourth belt is sleeved on the fourth driving wheel and the two fourth transmission wheels. The third driving mechanism is connected to the second driving shaft in driving connection. The third driving mechanism can also select a motor to drive the second driving shaft to rotate, which can drive the third driving wheel and the fourth driving wheel to rotate. The rotation of the third driving wheel can drive the third belt to transmit on the two third transmission wheels, and the rotation of the fourth driving wheel can drive the fourth belt to transmit on the two fourth transmission wheels, so as to realize the transportation of the PCB board 90 on the second conveyor path 70.

[0081] Based on the same inventive concept, in one embodiment, the second buffer station 71 may also be provided with two support platforms, one support platform is provided on the end surface of the third track plate 72 facing the second track plate 63, and the support platform is located on the inner circle of the third belt; the other support platform is provided on the end surface of the second track facing the third track, and the support platform is located on the inner circle of the fourth belt, so as to support the PCB board 90 on the second conveyor 70.

[0082] In one embodiment, a limiting roller 73 is provided at one end of the second conveying path 70 away from the detection track 30; the limiting roller 73 is connected to the end surface of the third track plate 72 facing the second track plate 63 and / or the end surface of the second track facing the third track, and the limiting roller 73 is used to abut the PCB board 90 on the second conveying path 70.

[0083] Specifically, Figure 4 As shown, the limiting roller 73 can be arranged on the right side of the second buffer station 71 on the rightmost side of the second conveyor 70, the limiting roller 73 is located on the third transmission, and the third belt is arranged between the third transmission wheel and the limiting roller 73; the limiting roller 73 can be connected to the end surface of the third track plate 72 facing the second track plate 63, or can be arranged on the end surface of the second track plate 63 facing the third track plate 72, or the limiting roller 73 can be arranged on both end surfaces. When the PCB board 90 in the second conveyor 70 reaches the last second buffer station 71, the limiting roller 73 abuts against the PCB board 90 to prevent the PCB board 90 from falling directly.

[0084] In one embodiment, the docking device further includes a safety grating 100; the safety grating 100 is assumed to be on the first conveying path 60 and is respectively connected to the first track plate 62 and the second track plate 63. Since the second conveying path 70 stores the qualified PCB board 90, the qualified PCB board 90 needs to be transported to a designated position, and the qualified PCB board 90 cannot be disturbed by the outside world; in order to prevent external interference, the safety grating 100 can be set, and when the operator puts his hand above the first conveying track, the safety grating 100 can give a corresponding prompt to remind the operator to avoid touching the first conveying track.

[0085] It is understandable that since the unqualified PCB boards 90 conveyed by the second conveyor track need to be repaired, the safety grating 100 does not need to be arranged on the second conveyor track.

[0086] In one embodiment, please refer to Figure 4 The docking device also includes a plurality of photoelectric sensors 110 ; a photoelectric sensor 110 is provided in each first cache station 61 and each second cache station 71 , and the photoelectric sensor 110 is used to detect whether there is a PCB board 90 on the first cache station 61 or the second cache station 71 .

[0087] For example, when each photoelectric sensor 110 detects that there is a PCB board 90 on the first cache station 61 or the second cache station 71, a relevant instruction is sent to control the detection track 30 to stop running; similarly, when the photoelectric sensors in the first cache station 61 and the second cache station 71 detect that there is no PCB board 90, the detection track 30 is controlled to continue working to transport the PCB board 90.

[0088] It is understandable that when one of the buffer stations is full, the inspection track 30 may contain a defective board or a qualified board. When the inspection track 30 contains a defective board, the operator has not re-inspected the defective board, and the inspection mechanism flows out multiple defective boards and fills up the second conveyor 70. At this time, the inspection track 30 stops running. After the operator has finished re-inspecting the defective boards, there is an empty buffer station on the second conveyor 70, and the inspection track 30 can run again. When the inspection track contains a qualified board, the downstream of the docking device is blocked, and the inspection mechanism flows out multiple qualified boards and fills up the first conveyor 60. At this time, the inspection track 30 stops running. After the operator dredges the downstream equipment and makes the first conveyor 60 have an empty buffer station, the inspection track 30 can run again. It should be noted that the downstream equipment refers to the equipment used to receive the qualified boards flowing out of the first conveyor 60. .

[0089] In one embodiment, the docking device includes a plurality of first conveying paths 60 and a plurality of second conveying paths 70, and the plurality of first conveying paths 60 and the second conveying paths 70 are arranged along the length direction of the slide rail 20, and the plurality of first conveying paths 60 and the second conveying paths 70 are parallel to the detection track 30. In order to add more cache stations and improve the production efficiency of the PCB board 90, in this embodiment, a plurality of first conveying paths 60 and the second conveying paths 70 are provided. When the cache station of one of the conveying paths is full, the detection track 30 can be moved so that the detection track 30 conveys the PCB board 90 to another conveying path. When it is detected that all the first conveying paths 60 or all the second conveying paths 70 are full, the detection track 30 stops running.

[0090] For the first driving mechanism 80, please refer to Figure 1 The first driving mechanism 80 is in transmission connection with the detection track 30, and is used to drive the detection track 30 to slide along the slide rail 20, so that the detection track 30 is flush with the first conveying path 60 or the second conveying path 70 in sequence. When the detection component 40 detects that the PCB board 90 on the detection track 30 is qualified, the first driving mechanism 80 drives the detection track 30 to slide along the slide rail 20, so that the detection track 30 is flush with the first conveying path 60, so as to convey the qualified PCB board 90; when the detection component 40 detects that the PCB board 90 on the detection track 30 is unqualified, the first driving mechanism 80 drives the detection track 30 to move along the slide rail 20, so that the detection track 30 is flush with the second conveying path 70, so as to convey the unqualified PCB board 90.

[0091] Specifically, the first driving mechanism 80 may be a motor, and the motor drives the detection track 30 to slide on the slide rail 20 via a screw rod.

[0092] In one embodiment, Figure 4 As shown, the docking device also includes a plurality of connection pads 120; the connection pads 120 include a fixed portion and a bent portion perpendicular to the fixed portion, and the fixed portion and the bent portion are integrally formed; the bent portion is fitted and fixed to the end surface of the first track plate 62 away from the second track plate 63, and the fixed portion is fixedly connected to the receiving platform 50. The fixed connection can be welded or screwed. It is understandable that the end surface of the third track plate 72 away from the track plate is also provided with a plurality of connection pads 120.

[0093] In one embodiment, in order to protect various components on the receiving platform 50, such as Figure 3 As shown, it also includes a support sheet metal 130. The outer side of the first track plate 62 and the outer side of the third track plate 72 are covered with the support sheet metal 130. The support sheet metal is used to cover various drive mechanisms and can support the overall frame. Based on the same inventive concept, a protective cover 140 can also be set on the first conveying path 60 to protect the qualified PCB board 90 on the first conveying path 60.

[0094] The working principle of the docking device in the embodiment of the present invention is:

[0095] The detection track 30 is first aligned with the first conveyor 60. When the detection component 40 detects that the PCB board 90 on the detection track 30 is qualified, the detection track 30 directly conveys the qualified PCB board 90 to the first conveyor 60. When the detection component 40 detects that the PCB board 90 on the detection track 30 is unqualified, the first drive mechanism 80 drives the detection track 30 to move along the slide rail 20, so that the detection track 30 is aligned with the second conveyor 70, and the detection track 30 conveys the unqualified PCB board 90 to the second conveyor. When all the photoelectric sensors 110 in the first conveyor 60 or the second conveyor 70 detect the presence of the PCB board 90, the detection track 30 stops running.

[0096] When there are multiple first conveyor lanes 60 or multiple second conveyor lanes 70, the detection track 30 is first aligned with one of the first conveyor lanes 60. When the photoelectric sensors 110 in the first conveyor lanes 60 detect that there are PCB boards 90 in the first cache stations 61 of the first conveyor lanes 60, and the detection component 40 detects that the PCB boards 90 on the detection track 30 are qualified, the first drive mechanism 80 drives the slide rail 20 of the detection track 30 to slide, so that the detection track 30 is aligned with another first conveyor lane 60 that is not full.

[0097] The embodiment of the present invention provides a PCB board docking device, which realizes automatic sorting of PCB boards 90 through the cooperation of a detection component 40, a detection track 30, a slide rail 20 and a first driving mechanism 80; by setting a plurality of first buffer stations 61 on a first conveying path 60 and a plurality of second buffer stations 71 on a second conveying path 70 to store a plurality of PCB boards 90 that have been inspected, it is realized that a plurality of PCB boards 90 are first buffered and then re-inspected, so that an operator can re-inspect a plurality of PCBs at a time, thereby effectively reducing the re-inspection time, reducing the waiting time for AOI inspection, and improving the production efficiency of PCB boards 90; when an operator has re-inspected a PCB board 90 on a track, he can re-inspect a PCB board 90 on another track, so that one operator can re-inspect a plurality of PCB boards 90 in a centralized manner; similarly, after an operator has re-inspected a PCB board 90 of a device, he can re-inspect a PCB board 90 buffered by a next device in a centralized manner, so that one operator can re-inspect a plurality of devices, thereby effectively reducing the labor cost.
