Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the carrier tray for PCB in this embodiment includes a main body, a carrying area and a limiting portion surrounding the carrying area, wherein one side of the main body is provided with a carrying area, and the other side of the main body is provided with a receiving cavity (not shown in the figure) for stacking a plurality of main bodies. A plurality of barrier strips 2 are arranged in the bearing area at intervals, the barrier strips 2 are used for dividing the bearing area into a plurality of grids 3, and each grid 3 is used for placing a PCB. The bottom of the grid 3 is provided with a plurality of protruding parts 4 which are distributed at intervals, when the PCB is placed in the grid 3, the PCB can be contacted with the plurality of protruding parts 4, so that the contact area between the PCB and the bottom of the grid 3 can be reduced, the purpose of reducing friction between the PCB and the grid is achieved, air at the bottom of the PCB and the bottom of the grid 3 can be circulated, and the stability of the quality of a PCB product is facilitated; further, the strength of the bottom of the grid 3 can be increased by providing the projection 4. The barrier strip 2 is provided with a fracture 21, and the fracture 21 enables a position for a person to conveniently take the PCB between the two grids 3. Through set up fracture 21 on blend stop 2, can be so that the area of check 3 design and the area size of PCB do not differ greatly, also do not influence the convenience that personnel took out PCB from check 3 (personnel can follow in fracture 21, and not go to get PCB from the lower hand in the clearance between PCB and blend stop 2). The bottom of the break 21 is not higher than the top of the boss 4, which can further improve the convenience of taking out the PCB from the grid 3.

Specifically, the shape of each lattice 3 follows the shape of a PCB. Preferably, as shown in fig. 1, the corners around each grid 3 are respectively provided with a relief portion 31, and the periphery of the relief portion 31 is rounded. By adopting the scheme, when a person places and takes the PCB, the sharp corners around the PCB interfere with the corners of the grids 3, so that the corners of the product are poor, or the corners of the carrying tray are scratched, and the service life is influenced.

Specifically, the opening of the accommodating cavity becomes smaller from the other side of the main body to one side of the main body. In this embodiment, the side of the main body provided with the bearing area can be an upper side, and the side of the main body provided with the accommodating cavity can be a lower side, so that the opening of the accommodating cavity becomes smaller from the lower side to the upper side. By adopting the mode, when the plurality of main bodies are stacked, the adjacent two main bodies are completely attached, so that the two main bodies are not convenient to separate.

Specifically, as shown in fig. 1, the limiting part is composed of four limiting strips 1 which are sequentially connected end to end. The four stop strips 1 form a rectangular bearing area in a substantially enclosed manner, and a plurality of barrier strips 2 are arranged in the rectangular bearing area. Preferably, the side of each stop strip 1 facing away from the carrying area may have a first support portion 11, and the side of each stop strip 1 facing the carrying area may have a second support portion 12. Further, each of the bars 2 may also be provided with a second support portion 12 on both sides facing the grid 3. Preferably, the top of the second supporting portion 12 is 2.5 to 3mm higher than the bottom of the corresponding grid 3.

With the above arrangement, when a plurality of main bodies are stacked on each other, the first and second support portions 11 and 12 provided on the main body below can be used to support the main body above, preventing the main body above from rubbing the PCB in the grid 3.

Specifically, the shape of the protruding portion 4 may be various shapes such as a circle, a square, an arc, and a diamond. As shown in fig. 1, the protruding portion 4 is preferably square or diamond-shaped, and such a regular shape is adopted, which facilitates reducing the manufacturing difficulty and cost of the forming mold of the main body.

Specifically, as shown in fig. 1, the main body further includes an edge portion 5 connected to the bottom of the position-limiting portion and extending in a direction parallel to the bearing region. Through being equipped with border portion 5, can be convenient for personnel take and carry the dish, 5 another important effects in border portion are, can promote the toughness of carrying the dish, avoid personnel to carry the easy breaking and damage of taking place in the edge of dish in the operation process repeatedly, can improve the life who carries the dish.

In summary, the carrying tray for the PCB in this embodiment includes a main body, one side of the main body is provided with a carrying area and a limiting portion which is surrounded and blocked outside the carrying area, the other side of the main body is provided with an accommodating cavity for stacking a plurality of main bodies, a plurality of barrier strips 2 are arranged at intervals in the carrying area, the carrying area is divided into a plurality of grids 3 by the barrier strips 2, the bottom of the grids 3 is provided with a plurality of protrusions 4 distributed at intervals, the barrier strips 2 are provided with fractures 21, and the bottoms of the fractures 21 are not higher than the tops of the protrusions 4. Compared with the base plate in the prior art, the carrying disc in the embodiment is adopted to operate the PCB between the forming station and the inspection station, so that the PCB can be prevented from being scratched, the method for standardizing the PCB taking by personnel is facilitated, and the reject ratio of the PCB caused by the personnel method is reduced.
