Description

TECHNICAL FIELD

[0001] The utility model relates to a size quick confirmation tool, especially to a PCB multi-pasting plate slotting plate processing post outer size quick confirmation tool. BACKGROUND

[0002] When carrying out multi-pasting plate operation (such as battery related products, 1set>30pcs pasting plate) to PCB, no spacing pasting plate or spacing slotting plate and the like are adopted to process the required shape and structure on the substrate, due to the material characteristics of the processed substrate, different reaction forces are generated on the cutting tool during the slotting plate processing process due to the rigidity and toughness of the substrate, and the cutting tool is prone to jumping during the slotting plate process, thereby causing the slot width or inner pcs size to exceed the standard, for example, the design requires that the slot width is 0.2mm, but after the cutting tool jumps, the slot width may reach 0.3mm or even more. This will affect the subsequent processing procedure of the pasting plate.

[0003] At present, the size of the pasting plate is mainly confirmed by manual measurement, however, this method is time-consuming and difficult to keep up with the production rhythm. Although manual measurement can ensure the size accuracy of the first piece, process sampling and the last piece, it cannot realize 100% measurement coverage of the product after slotting plate processing. This means that during batch production, a large number of PCB pasting plates will directly enter the next process without accurate measurement, making it difficult to effectively guarantee the forming size of the product designed in this way, and bringing great potential risk to the product quality. Therefore, a more efficient and comprehensive size confirmation method is urgently needed to solve this problem in the processing of aluminum substrate pasting plate. SUMMARY

[0004] In order to overcome the shortcomings in the prior art, the purpose of the utility model is to provide a PCB multi-pasting plate slotting plate processing post outer size quick confirmation tool.

[0005] A PCB multi-pasting plate slotting plate processing post outer size quick confirmation tool, comprising a base and positioning nails, the top of the base is provided with a plurality of positioning nails on the front and rear sides, the distribution positions of the positioning nails correspond to the slot positions in the PCB, the positioning nails on the front and rear sides are arranged asymmetrically, the height of the positioning nails is set to penetrate the slots of at least 5 layers of PCB at the same time, and a top excess is reserved to avoid mechanical interference with the surface circuit or metallized hole of the PCB.

[0006] Optionally, it further comprises target nails, the top of the base is provided with target nails, and the top end height of the target nails is higher than the top end height of the positioning nails.

[0007] Optionally, it further comprises a material taking plate, the material taking plate is movably arranged on the top of the base through the positioning nails, the four edges of the material taking plate are provided with extension parts, and grooves are formed on the base corresponding to the extension parts on the material taking plate.

[0008] Optionally, the positioning nail outer edge and the target nail tip are provided with chamfers.

[0009] Optionally, the base is provided with a cushion block at each of the four corners of the bottom.

[0010] The utility model discloses the beneficial effects are:

[0011] 1. The utility model discloses a quick confirmation tool for the outer size of PCB multi-ply board after milling, which can detect the milling groove of the multi-ply board in batches. During operation, the milling groove process edge of the PCB multi-ply board is aligned with the positioning nail and is sleeved. The qualified product can be accurately molded. The product with size deviation or deformation cannot be sleeved with the positioning nail and is quickly screened out. The precise gap between the milling groove and the positioning nail forms physical limiting, which eliminates artificial determination error and improves the efficiency compared with manual visual inspection or the use of measuring tools.

[0012] 2. The utility model discloses a material taking plate. When the material in the tool needs to be taken out, the extension part of the material taking plate is used to lift upward. The worker does not need to take out the plate one by one, and the tool and the material can be quickly separated. The plate is uniformly lifted upward, which can be separated from the tool without damage. At the same time, the time for taking out the plate is reduced. BRIEF DESCRIPTION OF DRAWINGS
