In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0027] In the related technology, due to the special characteristics of COB direct display products, the LED is relatively small; before the process is completed, the LED lacks protection; the entire process must rely on the process edge to increase the distance between the LED and the machine and process tools to increase the process yield. However, this will occupy the effective use area of the PCB board.
[0028] In order to increase the effective use area of PCB board, such as Figures 1 to 3As shown, in this embodiment, the PCB process edge jig is used to process the PCB board 1, and the PCB process edge jig includes: a frame 10, a plurality of mounting portions 20, and a plurality of connectors 30. The frame 10 includes a plurality of positioning members 11 arranged in sequence, and the PCB board 1 is detachably mounted in the frame 10. Each positioning member 11 is provided with at least one mounting portion 20. The plurality of connectors 30 are arranged in one-to-one correspondence with the plurality of mounting portions 20, and the connectors 30 are detachably mounted in the corresponding mounting portions 20.
[0029] According to the technical solution of the present embodiment, the frame 10 includes a plurality of positioning members 11 arranged in sequence, the PCB board 1 is detachably mounted in the frame 10, each positioning member 11 is provided with at least one mounting portion 20, a plurality of connecting members 30 are arranged in one-to-one correspondence with the plurality of mounting portions 20, and the connecting members 30 are detachably mounted in the corresponding mounting portions 20. Through the above arrangement, the PCB board 1 is detachably fixed in the frame 10, and the connecting members 30 are connected between the corresponding mounting portions 20 and the PCB board 1, thereby making the position of the PCB board 1 more stable. At the same time, the plurality of positioning members 11 play the role of process edges, and thus there is no need to design process edges on the PCB board 1 itself, thereby making the effective use area of the PCB board 1 larger. Therefore, the technical solution of the present embodiment effectively solves the problem in the related art that the PCB board has a reduced effective utilization rate due to the existence of process edges.
[0030] Specifically, the positioning member 11 is a plate, and the frame 10 includes four positioning members 11. The four positioning members 11 are connected to each other or are independently arranged. The mounting portion 20 is a mounting recess.
[0031] In the prior art, the efficiency of cutting the process edge on the PCB board is relatively low, and multiple devices are required to meet the cutting capacity. In addition, the cutting process has high risks, and abnormal cutting leads to the scrapping of finished products, resulting in relatively large losses. The technical solution of this embodiment does not require cutting the process edge, thereby effectively solving the above technical problems.
[0032] like Figures 2 to 5 As shown, in this embodiment, the mounting portion 20 is disposed on the lower surface of the frame 10. The above arrangement can prevent the connector 30 from interfering with the structure on the upper surface of the frame 10, thereby preventing the connector 30 from affecting the processing of the PCB board 1.
[0033] like Figure 4 As shown, in this embodiment, the height a of the mounting portion 20 and the thickness b of the PCB board 1 satisfy: 0.3≤a / b≤0.6. The above arrangement can ensure the stability of the connection. Specifically, in this embodiment, a / b=0.5.
[0034] like Figure 2 and Figure 3As shown, in this embodiment, the width of the mounting portion 20 gradually increases from the center of the frame 10 to the periphery of the frame 10. The above arrangement can make the connection of the connector 30 to the mounting portion 20 more stable.
[0035] like Figure 2 and Figure 3 As shown, in this embodiment, the connector 30 includes a first connector 31 and a second connector 32 connected to each other, the first connector 31 is disposed in the mounting portion 20, and the second connector 32 is connected to the PCB board 1. The above arrangement enables the connector 30 to be stably connected to the frame 10 and the PCB board 1.
[0036] The first connecting portion 31 and the second connecting portion 32 are an integral structure, that is, the connecting member 30 is a connecting block.
[0037] like Figure 2 and Figure 3 As shown, in this embodiment, the width of the first connection portion 31 gradually decreases from the first connection portion 31 to the second connection portion 32. The shape of the first connection portion 31 is adapted to the shape of the mounting portion 20, that is, the shape of the first connection portion 31 is a trapezoid, and the shape of the mounting portion 20 is also a trapezoid, so that the connection between the first connection portion 31 and the mounting portion 20 is more stable.
[0038] In an embodiment not shown in the figure, the mounting portion 20 can also be other shapes, as long as the width of the mounting portion 20 on the side close to the frame 10 is smaller than the width on the side away from the frame 10, so as to achieve the stability of the position of the frame 10 and the PCB board 1.
[0039] It should be noted that the second connection portion 32 is also trapezoidal in shape. A trapezoidal notch is provided at the edge of the PCB board 1, and the second connection portion 32 is inserted into the trapezoidal notch. In this way, the PCB board 1 can be fixed inside the frame 10 under the action of the two trapezoidal notches.
[0040] like Figure 2 As shown, in this embodiment, a plurality of communication ports 12 are provided on the inner surface of the frame 10, and the plurality of communication ports 12 are provided one-to-one correspondingly to the plurality of mounting portions 20 and are in communication with the mounting portions 20. The provision of the communication ports 12 enables the insertion of the connector 30.
[0041] like Figures 2 to 5 As shown, in this embodiment, when the connecting member 30 is installed in the corresponding mounting portion 20, the bottom surface of the connecting member 30 is flush with the bottom surface of the frame 10. The above arrangement can make the bottom surface of the frame 10 flush, so that the frame 10 can be stably placed on the preset surface, which makes it more stable during subsequent processing.
[0042] like Figure 1 and Figure 4 As shown, in this embodiment, the top surface of the frame 10 is higher than the top surface of the PCB board 1. The above-mentioned setting enables the multiple positioning members 11 to form a dam structure, which can realize the function of blocking glue. Specifically, when the COB product is sealing the chip, the multiple positioning members 11 form a dam structure at the edge of the PCB board 1 to prevent the packaging glue from flowing out and causing insufficient packaging glue.
[0043] like Figures 1 to 5 As shown, the PCB process edge fixture of this embodiment has the following advantages:
[0044] The process edge of the PCB product is eliminated, and the utilization rate of the PCB board 1 is improved. Since there is no need to set the process edge, the cutting process is omitted, the process complexity and equipment investment are reduced, and the output is improved. The top surface of the frame 10 protrudes from the top surface of the PCB board 1, and the dam dispensing process before the PCB packaging process can be eliminated. The frame 10 is detachable and reusable, saving costs and resources.
[0045] According to another aspect of the present application, a PCB board processing device is provided. The PCB board processing device of this embodiment includes a PCB process edge fixture, and the PCB process edge fixture is the above-mentioned PCB process edge fixture. The above-mentioned PCB process edge fixture can effectively fix the PCB board 1 and realize the function of the process edge, that is, there is no need to design the process edge on the PCB board 1, so that the effective use area of the PCB board 1 can be larger, so the PCB board processing device with the above-mentioned PCB process edge fixture also has the above-mentioned advantages.
[0046] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0047] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0048] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
[0049] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
