AI Technical Summary
Copper leakage is prone to occur during the separation process of encoder PCB boards, which makes it difficult for customers to assemble.
Grooves are set on the edges of the PCB board, and V-cut marking lines are set on the connecting ribs. The V-cut marking lines guide the operator to make cuts. Combined with the V-cut no-catch zone and the arrayed PCB board structure, the cutting accuracy is improved.
This reduces the precision requirements for PCB depaneling, decreases the scrap rate of individual PCB boards, and improves depaneling quality and customer assembly efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB board manufacturing and processing technology, and in particular to an encoder board anti-copper leakage separation structure. Background Technology
[0002] An optical encoder is a digital inspection device integrating optics, mechanics, and electronics. It is a sensor that converts the mechanical and geometric displacement of a shaft into pulse or digital signals through a photoelectric conversion circuit. To improve encoder accuracy, multiple completely independent receivers are typically used internally. Accuracy is improved by performing compensation calculations on the raw signals acquired by these receivers. To ensure the stability and reliability of the acquired raw signals, each receiver needs to be aligned with a scale grating. Therefore, each receiver must be placed on an independent PCB for easy alignment.
[0003] Currently, during the PCB depaneling process for encoders, it has been found that copper leakage occurs when the PCB edge is slightly recessed after depaneling. Figure 1 Because the PCB board inside this encoder is circular, the connecting ribs were not cut completely or copper was exposed during the board separation process, causing difficulties for the client to assemble. Utility Model Content

[0005] To achieve the above objectives, this utility model provides an encoder board anti-copper separation structure, a substrate, on which a plurality of PCB single boards and a plurality of corner areas are provided, and connecting ribs are provided between adjacent PCB single boards and corner areas. Multiple grooves are provided on the edges of the PCB single boards, and one end of the connecting rib is connected to the groove wall of the groove.

[0007] The connecting rib is marked with a V-cut line.
[0008] As a further description of the above technical solution:

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "adjacent," and "connect" should be interpreted broadly.

[0028] Please see Figure 1-3 This utility model provides an encoder board anti-copper separation structure, which includes a substrate, on which a plurality of PCB single boards 1 and a plurality of corner areas 2 are disposed, and a connecting rib 4 is disposed between adjacent PCB single boards 1 and corner areas 2. The feature is that a plurality of grooves 5 are disposed on the edge of the PCB single board 1, and one end of the connecting rib 4 is connected to the groove wall of the groove 5.
[0029] The connecting rib 4 is provided with a V-cut marking line 6. This can remind the operator to cut along the V-cut marking line, improving cutting accuracy and thus improving the quality of plate separation.
