[0002] At present, the three most common defects in the COB direct display module die bonding process are: offset, dead light, and bad pixels. The expansion and shrinkage and warpage of the PCB board are the key factors affecting the offset and dead light defects of the die bonding process. In order to improve the yield, a PCB sizing machine is added before the die bonding process to detect the warpage and expansion and shrinkage of the PCB board. In the actual production process, the incoming PCB board can be inspected and put into use according to the grade to ensure the yield. The existing PCB sizing machine is a main inspection equipment that detects the PCB board. After the PCB board is inspected, the mechanical arm grabs the PCB board and places it on the workbench. The PCB boards are stacked directly, and the risks of related defects such as overlapping scratches and static electricity on the boards are extremely high. CN 112809639 A discloses a PCB board production placement box with good shock absorption effect and convenient interlayer packaging, but the placement box is not suitable for grabbing and placing by a mechanical arm, and cannot be adaptively adjusted according to the size of the PCB board. Therefore, in order to avoid defects before the PCB board is put into use, the overall yield of Mini LED COB products is improved. To address this problem, it is necessary to design a fixture that can match the PCB sizing machine robot arm to pick up and place PCB boards, and at the same time realize automatic stratification of boards, which can effectively improve the problem; secondly, using a fixture to undertake PCB board loading operations can improve work efficiency and reduce manpower.

For example, when an element is referred to as being "connected to" another element, it may be directly or indirectly connected to the other element.

[0031] In addition, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] like Figures 1 to 4 The schematic diagram of the PCB placement fixture after the corresponding division provided by the utility model includes:

[0033] The box body 10 includes a bottom plate 11, a top plate 12, and two side plates 13 connected between the bottom plate 11 and the top plate 12, and a plurality of slide rails 14 are arranged between the two side plates 13;

[0034] The fixing mechanism 20 includes a first fixing mechanism 21 and a second fixing mechanism 22 which are arranged opposite to each other. The first fixing mechanism 21 is fixedly connected to one of the side plates 13, and the second fixing mechanism 22 is movably connected through the slide rail 14. The fixing mechanism 20 includes an end plate 23, a limiting mechanism 30 and a plurality of rotating shafts 24. The plurality of rotating shafts 24 are arranged at intervals in the vertical direction and fixed on the end plate 23. Each rotating shaft 24 is provided with a plurality of supporting parts 25. The limiting mechanism 30 includes a plurality of limiting components 31 which are arranged at equal intervals with the rotating shaft 24, so as to limit the rotating shaft 24 from driving the supporting part 25 to rotate between the first position and the second position.

[0035] Furthermore, the device further includes: a top plate 12, a card slot 15 is provided on the top plate 12, and a fixing kit 27 extending toward the card slot 15 is provided on the top of the second fixing mechanism 22 to lock the position of the second fixing mechanism 22. Since the second fixing mechanism 22 is movable in the direction of the slide rail 14, it is convenient to flexibly adjust according to the size of the PCB board. After adjusting to the position of the second fixing mechanism 22, the position is fixed by the fixing kit. In some embodiments, the fixing kit 27 is a bolt and a bolt fastener. When the position needs to be adjusted, the bolt fastener is loosened, and when it needs to be fixed, it can be tightened, which is convenient for adjustment at any time.

[0036] Furthermore, a handle 16 is provided on the top plate 12 to facilitate technicians to lift the fixture for displacement.

[0037] Furthermore, the side plate 13 is provided with a plurality of through holes 26 , and the design of the through holes can reduce the weight of the fixture, making it easier to lift and move.

[0038] Furthermore, the support portion 25 is sleeved on the shaft 24 and has an extension portion extending radially toward the shaft 24. Two support portions 25 are provided on each shaft 24. The first fixing mechanism 21 and the second fixing mechanism 22 are both provided with symmetrically distributed support portions 25. Each group of symmetrically distributed support portions 25 is used to support a PCB board, that is, the PCB board is placed on the extension portion of the support portion 25. In addition, the sleeved manner can be used to quickly disassemble or increase the number of support portions based on the need for board storage.

[0039] Furthermore, if Figure 5 As shown, the limiting mechanism 30 includes a limiting assembly 31 and a limiting plate 32. The limiting plate 32 has a plurality of limiting grooves 33. The limiting assembly 31 is sleeved on the end of the rotating shaft 24 and moves in a limited position in the limiting grooves 33. In some embodiments, the number of the rotating shafts 24 is 15, and 15 limiting grooves 33 are correspondingly provided on the limiting plate 32. The limiting assembly 31 is T-shaped and can rotate in the limiting grooves 33, and drives the support portion on the rotating shaft to rotate between the first position and the second position, as shown in FIG. Figure 5The solid line position and the dotted line position of the limit assembly shown in the figure are the two extreme positions of the limit, corresponding to the first position and the second position of the support part, wherein the first position is when the support part is rotated to the vertical direction, and the second position is when the support part is rotated to the horizontal direction.

[0040] Furthermore, the slide rails 14 include four, two of which are arranged near the top plate 12 , and the other two are arranged near the bottom plate 11 . Such an arrangement can better form a stable structure and ensure that the second fixing mechanism 22 is parallel to the first fixing mechanism 21 .

[0041] Furthermore, the number of the rotating shafts 24 is 12 to 15, which can accommodate multiple PCB panels and effectively improve actual production efficiency.

[0042] The method of using the jig includes: the mechanical arm grabs the PCB board and extends it into the box body 10 from the area near the bottom plate 11, and moves toward the top plate 12 to the highest placement position. During the upward movement, when the PCB board reaches the position of the support part 25, the PCB board abuts against the support part 25 upward, and the rotation shaft 24 drives the support part 25 to rotate upward to the first position, that is, it is completely in the vertical direction. At this time, the PCB board can smoothly pass through the placement position located below and continue to move upward to the highest placement position. When the PCB board is placed at the support part 25, the support part 25 is locked by the limiting mechanism 30 at the second position, that is, the support part 25 is rotated to the horizontal direction to form a support table, and a group of relative support parts 25 in the fixing mechanism 20 on both sides are used to lift a PCB board, and multiple PCB boards are placed in sequence from top to bottom. The advantage of this device is that it can match the action of the mechanical arm, realize automatic stratification, and effectively solve the problems of scratches and static electricity generated by PCB board stacking.
