DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0029] The specific implementation of the present application is described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 4 The present application discloses a sorting machine, comprising a feeding mechanism 10, an upper detection mechanism 20, a lower detection mechanism 30, a discharge table 40 and a first conveying mechanism 50. The upper detection mechanism 20 is arranged above the feeding mechanism 10, and the feeding mechanism is used to store the plates. The discharge table 40 is arranged at a distance on one side of the feeding mechanism 10, and the lower detection mechanism 30 is arranged between the discharge table 40 and the feeding mechanism 10. The direction in which the feeding mechanism 10, the lower detection mechanism 30 and the discharge table 40 extend is a first direction, and the first conveying mechanism 50 can reciprocate along the first direction, and is used to convey the plates from the feeding mechanism 10 to the discharge table 40.

[0031] During use, the upper detection mechanism 20 and the lower detection mechanism 30 can use high-speed cameras and line cameras to capture information such as characters, bar codes, QR codes, etc. on the plate, and feed back the corresponding information to the controller in a timely manner.

[0032] Combination Figure 5 and Figure 6When in use, the plate, i.e., PCB, is transported to the loading position through the loading mechanism 10. The loading position refers to the position where the first handling mechanism 50 can absorb the plate; at this time, the upper detection mechanism 20 located above obtains the detection information of the upper surface of the plate, and then the first handling mechanism 50 moves to the loading position to absorb the plate and drives the plate to move along the first direction. During the movement, it passes the position where the lower detection mechanism 30 is located. At this time, the lower detection mechanism 30 located below obtains the detection information of the lower surface of the plate, and the first handling mechanism 50 moves to place the plate on the unloading table 40, and realizes the detection of the upper and lower surfaces of the plate through the loading process and the handling process. Compared with the traditional single-sided detection equipment, it can realize the detection of both sides of the PCB plate in one loading, avoid the situation where defective products are outflowed to customers due to missed detection, and improve production efficiency.

[0033] Reference Figure 4 Furthermore, in one embodiment, the sorting machine further includes a first moving mechanism, which is connected to the lower detection mechanism 30 and is used to drive the lower detection mechanism 30 to move along a second direction, and the second direction intersects with the projection of the first direction on the plane where the unloading platform 40 is located. Optionally, the first direction is the X direction of the spatial coordinate system, and the second direction is the Y direction of the spatial coordinate system. When the first transport mechanism 50 drives the plate to move along the X direction to the top of the lower detection mechanism 30, the first moving mechanism drives the lower detection mechanism 30 to move along the Y direction to more comprehensively capture the information of the lower surface of the plate.

[0034] Reference Figure 1 and Figure 2 Optionally, in one embodiment, the upper detection mechanism 20 includes a mounting frame 210 and a first camera 220, the first camera 220 is fixed to the middle of the mounting frame 210, and the mounting frame 210 is located above the first transport mechanism 50. Through the first camera 220 located in the middle, the overall image information of the upper surface of the plate can be captured to avoid missing the plate information.

[0035] Furthermore, in one embodiment, the upper detection mechanism 20 further includes a second camera 230 and a second moving mechanism disposed on the mounting frame 210, and the second moving mechanism is connected to the second camera 230, and is used to drive the second camera 230 to move along the first direction and / or the second direction. The second moving mechanism drives the second camera 230 to move along the X direction or the Y direction, and local information on the upper surface of the plate can be photographed to obtain more detailed information on the upper surface.

[0036] Reference Figure 2 In one specific embodiment, the second camera 230 is provided with a ring light source for illuminating the upper surface of the plate.

[0037] Optionally, the first moving mechanism and the second moving mechanism may be implemented using existing technologies, such as a linear motor module, an XY-axis guide module, etc., which will not be elaborated herein.

[0038] Reference Figure 1 and Figure 3 Specifically, in one embodiment, the loading mechanism 10 includes a silo 110 and a first rack 120 and a second rack 130 located in the silo 110. The first rack 120 includes a plurality of first support blocks 122 arranged at intervals, and the second rack 130 includes a plurality of second support blocks 132 arranged at intervals. When the first rack 120 drives the plate to move to the staggered arrangement of the first support blocks 122 and the second support blocks 132, the second rack 130 can drive the plate placed on the first rack 120 to move along the height direction of the side wall of the silo 110. First, the plate is placed flat on the multiple first support blocks 122 of the first material rack 120. The first material rack 120 is driven by the horizontal drive mechanism to gradually approach the second material rack 130. When it moves to the side of the second material rack 130, the first support block 122 continues to move along the gap between two adjacent second support blocks 132 until the first support block 122 and the second support block 132 are arranged alternately. At this time, the plate is placed on both the first support block 122 and the second support block 132. Then the second material rack 130 is driven by the vertical drive mechanism to move upward and simultaneously drive the plate to the loading position. After the first transport mechanism 50 transports the plate, the second material rack 130 moves downward to reset, and the first material rack 120 continues to drive the plate to the second material rack 130 for continuous loading.

[0039] Reference Figure 1 and Figure 3 Furthermore, in one embodiment, the feeding mechanism 10 also includes a whole plate member, which can move in a direction away from or close to the side wall of the silo, and is used to press the plate against the side wall of the silo to align the edges of the plate. Since the edges of the stacked plates are not aligned due to the multiple plates transported upward by the second rack 130, the second rack 130 drives the plate to move upward to be flush with or lower than the highest point of the silo side wall. At this time, one side of the plate is against the silo side wall, and the other side of the plate is pushed by the whole plate member to press the plate against the material as a whole, so that the plate is positioned with the surface of the silo side wall as a reference to ensure that the plate is flat during the subsequent sorting process. Optionally, the whole plate member can be driven by a linear motor or a guide rail slider mechanism to move in a direction away from or close to the side wall of the silo. Optionally, the whole plate member includes two, and the two whole plate members are arranged perpendicular to each other, and the two sides of the plate are respectively pressed against the two perpendicular silo side walls, so that the four sides of the plate are flat.

[0040] Reference Figure 1 , Figure 3 and Figure 4In one embodiment, the lower detection mechanism 20 includes a third camera, and the third camera captures the overall image information of the lower surface of the plate through the gap between the unloading table 40 and the loading mechanism 10.

When the electric controller obtains the detection information of the upper surface or the lower surface of the plate and identifies that one or both sides of the plate are unqualified, the electric controller promptly issues an instruction to control the first conveying mechanism 50 to convey the unqualified plate to the defective bin, so as to prevent defective products from flowing into subsequent workstations and reduce the occurrence of customer complaints.

[0043] Reference Figure 1 , Figure 3 and Figure 4 Furthermore, in one embodiment, the inspection machine further includes a conveyor line 60, which is arranged on a side of the unloading platform 40 away from the lower detection mechanism 30, and the unloading platform 40 can be raised and lowered in the height direction to be flush with the conveyor line 60.

By setting the partition mechanism 80 and the second conveying mechanism 90, the partition can be conveyed to the unloading platform 40, and then the plate can be placed on the partition to meet the packaging requirements of different plates.

[0045] Optionally, in one embodiment, the defective bin is arranged between the partition mechanism 80 and the conveyor line 60, and the defective bin is connected to the partition mechanism 80 and can extend or return to the bottom of the partition mechanism 80. The defective bin can be automatically extended or returned to the bottom of the partition mechanism 80 by the drive member. The drive member is connected to the electronic controller signal. When it is detected that the plate is unqualified, the discharge table 40 is lowered to a height lower than the defective bin. At this time, the defective bin extends above the discharge table 40, and the first conveying mechanism 50 is translated into position and then descends to convey the unqualified plate to the defective bin, and the defective bin is then returned to the bottom of the partition mechanism 80, and the discharge table 40 rises to the position to carry the qualified plate. Through the reasonable arrangement of the defective bin, not only can the space occupation be effectively reduced, but also the position of the defective bin adapts to the movement stroke of the first conveying mechanism 50, so as to realize automatic sorting.

[0046] Reference Figure 1 , Figure 3 and Figure 4 Furthermore, in one embodiment, the sorting machine further includes a paging machine 100, which is located above the conveyor line 60, and the second transport mechanism 90 is also used to transport the separator paper stored on the paging machine 100 to the unloading platform 40. By setting up the paging machine 100, the separator paper can be continuously output, and the second transport mechanism 90 transports the separator paper to the unloading platform 40, and then the plate is placed on the separator paper to meet the packaging needs of different plates.
