Description

Technical Field

[0001] The utility model relates to the technical field of a fixture for inspecting a gold-plated cover plate, in particular to a fixture for inspecting the plating leakage situation on the side of a gold-plated cover plate. Background Art

[0002] When the cover is electroplated with gold, the electroplating fixture clamps the side of the cover, so the side will be unevenly plated. In severe cases, some places on the side of the cover will not even have the electroplated gold layer, resulting in poor anti-oxidation performance of the cover, which is easy to rust over time and rust through the shell. At the least, the product will be returned or replaced, and at the worst, the original components in the customer's shell will fail, resulting in compensation.

[0003] However, the original inspection method is to use tweezers to pick up several pieces, turn them over under a microscope, and check whether there is any leakage on the sides of the four sides of the cover. This method is very labor-intensive, difficult to focus, and prone to incomplete inspection. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the utility model provides a fixture for checking the plating leakage situation on the side of a gold-plated cover plate.

[0006] (II) Technical solution

[0008] Preferably, the upper clamp and the lower clamp are made of aluminum alloy.

[0009] Preferably, the two sides of the groove A and the groove B are parallel to the two sides of the outer contour. By making the two sides of the groove A and the groove B parallel to the two sides of the outer contour, the focal length can be consistent under the microscope when it is subsequently turned over; its size is the same as the size of the cover plate to be tested.

[0010] Preferably, a top block A is bonded to one side of the groove A cavity by glue, and a top block B is bonded to the other side of the groove A cavity by glue.

[0011] Preferably, the top block A and the top block B are both made of aluminum alloy.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figure 1-3As shown, the utility model provides a fixture for checking the leakage of plating on the side of a gold-plated cover plate, comprising an upper fixture 1, a gold-plated cover plate 2, and a lower fixture 3. A groove A4 is provided on the inner side of the upper fixture 1, and the two ends of the lower fixture 3 are fitted with the two ends of the upper fixture 1. A groove B5 is provided on the inner side of the lower fixture 3, and the gold-plated cover plate 2 is arranged on the side of the groove A4 and the groove B5 provided on the inner side of the upper fixture 1 and the lower fixture 3. The material used for the upper fixture 1 and the lower fixture 3 is aluminum alloy. The two sides of the groove A4 and the groove B5 are respectively parallel to the two sides of the outer contour. By making the two sides of the groove A4 and the groove B5 parallel to the two sides of the outer contour, the focal length can be consistent under the microscope when it is subsequently flipped; its size is the same as the size of the cover plate to be inspected. A top block A6 is bonded to one side of the groove A4 cavity by glue, and a top block B7 is bonded to the other side of the groove A4 cavity by glue. The materials used for the top block A6 and the top block B7 are also made of aluminum alloy. The inside of the groove A4 and the groove B5 needs to be polished. By polishing the inside of the groove A4 and the groove B5, it is possible to effectively avoid damaging the electroplated gold layer of the cover plate.

[0023] In this embodiment, the two sides of the groove A4 and the groove B5 are parallel to the two sides of the outer contour respectively so that the focal length can be consistent under the microscope when it is subsequently flipped; its size is the same as the size of the cover plate to be inspected, and the inside of the groove A4 and the groove B5 are polished to effectively avoid damaging the electroplated gold layer of the cover plate.

[0024] The following is a detailed description of the working principle of this fixture for checking the leakage of plating on the side of the gold-plated cover plate.

[0025] like Figure 1-3 As shown, firstly, the lower fixture 3 is clamped and placed flat on the table, and the gold-plated cover plate 2 is stacked in the groove cavities of the groove A4 and the groove B5 with tweezers. The second step is to place the lower clamp 3 with the gold-plated cover plate 2 clamped under a microscope, turn over the base, let one of the edges of the gold-plated cover plate 2 be parallel to the table top, and the quality inspector uses a microscope to check whether there are any abnormalities on the edges of all the gold-plated cover plates 2 on the same plane; the third step is to turn over the base, let the other side of the gold-plated cover plate 2 be parallel to the table top, and the quality inspector uses a microscope to check whether there are any abnormalities on the edges of all the gold-plated cover plates 2 on the same plane; the fourth step is to cover the upper clamp 1, slide the upper clamp 1 to gently clamp the gold-plated cover plate 2, and then turn it 180 degrees so that the top cover faces downward, and remove the original lower clamp 3. At this time, the remaining two edges of the gold-plated cover plate 2 are exposed. We use the method of the second step to check whether there is any abnormality on one of the edges in the same plane of all the cover plates; the fifth step is to turn over the upper clamp 1, let the last edge of the gold-plated cover plate 2 be parallel to the table top, and the quality inspector uses a microscope to check whether there are any abnormalities on the last edge of the same plane of all the gold-plated cover plates 2; the inspection of the side surface leakage of the four sides of all the gold-plated cover plates 2 is now completed.
