Description

Technical Field

[0001] This utility model relates to the field of substrate component manufacturing, and in particular to a substrate component dimension and height inspection fixture. Background Technology

[0002] In the electronics manufacturing industry, substrate components (such as components on PCBs) are core parts of electronic products. With the continuous miniaturization and integration of components, the requirements for the dimensional and height accuracy of substrate products are also increasing. Therefore, specialized inspection fixtures have been designed for the dimensional and height inspection of substrate products. Existing substrate component dimensional and height inspection fixtures generally employ technologies such as mechanical sensors, laser rangefinders, or optical sensors to ensure that the product height meets design requirements through precise measurement. These fixtures can quickly and accurately detect height differences for each component, ensuring that the produced substrate components meet assembly standards.

[0003] Although existing inspection fixtures can meet production needs to a certain extent, they still have some defects and problems. For substrate components of different sizes and shapes, existing fixtures may need to be frequently adjusted or replaced, and they cannot fit substrate components of different sizes and heights well. Inaccurate positioning is prone to occur during the inspection process. In order to address this technical problem, this application proposes a substrate component size and height inspection fixture. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixture for inspecting the height of substrate components. By having an inspection block slide within the test slot, the distance between the inspection block and the substrate surface is the maximum floating distance for the inspected dimension. This solves the problem of inaccurate testing due to inconsistent substrate thickness when testing from the bottom surface of the substrate, and also avoids inaccurate testing caused by substrate deformation during testing. The structure is simple to design and easy to operate, greatly saving manufacturing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a substrate component dimension and height inspection fixture, comprising a base plate, a bracket fixedly connected to the rear end of the top of the base plate, a quick clamp provided at the front end of the bracket, four positioning posts fixedly connected to the front end of the top of the base plate, two guide shafts fixedly connected to the top of the base plate, both guide shafts being located behind the positioning posts, an upper cover plate slidably connected to the outer periphery of the guide shafts, two slide rails provided on the top of the upper cover plate, sliders slidably connected to the surfaces of the two slide rails, stop handles fixedly connected to the top of the two sliders, and an inspection stop block fixedly connected to the bottom center of the stop handles.

[0006] Furthermore, a test groove is provided on the surface of the upper cover plate, and the inspection block is disposed inside the test groove.

[0007] Furthermore, the two slide rails are fixedly connected to the left and right sides of the test slot.

[0008] Furthermore, a panel support is fixedly connected to the bottom of the upper cover plate, and the panel support is located directly above the positioning post.

[0009] Furthermore, the quick clamp is fixedly connected to the top of the upper cover plate at its bottom.

[0010] Furthermore, a base plate is provided on the top of the base plate, and the four positioning posts are all sleeved on the four corners of the base plate.

[0011] This utility model has the following beneficial effects:

[0012] 1. In this utility model, the upper cover plate is attached close to the surface of the substrate, and the inspection block slides in the test groove. The distance between the inspection block and the substrate surface is the maximum floating distance of the inspection size. This solves the problem of inaccurate testing due to the uneven substrate thickness when testing from the bottom surface of the substrate, and also avoids the problem of inaccurate testing caused by substrate deformation during testing.

[0013] 2. In this utility model, the substrate can be tested by the cooperation between the slider, the inspection block and the block handle. The structure is simple and easy to operate, which greatly saves manufacturing costs. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-3 This utility model provides an embodiment of a substrate component size and height inspection fixture, including a base plate 1, a bracket 2 fixedly connected to the rear end of the top of the base plate 1, a quick clamp 3 provided at the front end of the bracket 2, four positioning posts 9 fixedly connected to the front end of the top of the base plate 1, two guide shafts 8 fixedly connected to the top of the base plate 1, both guide shafts 8 being located behind the positioning posts 9, an upper cover plate 10 slidably connected to the outer periphery of the guide shafts 8, two slide rails provided at the top of the upper cover plate 10, sliders 4 slidably connected to the surfaces of the two slide rails, a stop handle 6 fixedly connected to the top of the two sliders 4, an inspection stop 5 fixedly connected to the bottom center of the stop handle 6, a test groove opened on the surface of the upper cover plate 10, the inspection stop 5 being located inside the test groove, the two slide rails fixedly connected to the left and right sides of the test groove, a panel support column 11 fixedly connected to the bottom of the upper cover plate 10, the panel support column 11 being located directly above the positioning posts 9, the quick clamp 3 fixedly connected to the top of the upper cover plate 10, a substrate 7 provided at the top of the base plate 1, and the four positioning posts 9 being sleeved on the four corners of the substrate 7;

[0021] Specifically, the quick clamp 3 is fixed to the base plate 1 by the bracket 2, which provides support when the position of the quick clamp 3 is adjusted up and down by the handle. The positioning post 9 can fix the substrate 7 to be tested and can also fit the panel support 11 under the upper cover plate 10, thereby increasing the stability during testing. When the upper cover plate 10 is lowered by the quick clamp 3, the guide shaft 8 on the base plate 1 acts as a limit to prevent the upper cover plate 10 from shifting. By pushing the stop handle 6, the slider 4 can slide on the slide rail, thereby driving the inspection stop 5 to test the substrate 7 under the upper cover plate 10.

[0022] Working principle: First, by opening the quick clamp 3 upwards, the substrate 7 to be inspected is placed on the four positioning posts 9 on the base plate 1. After the substrate 7 is placed, the handle of the quick clamp 3 is used to move it downwards, bringing the upper cover plate 10 connected below closer to the substrate 7, so that the panel support 11 below it coincides with the positioning posts 9 on the base plate 1. At this time, hold the stop block handle 6 and slide it upwards to check whether the stop block 5 can slide completely on the slider 4, that is, check whether the stop block 5 can move smoothly in the test groove on the upper cover plate 10. Since the distance between the stop block 5 and the substrate 7 is the maximum floating distance, if it can slide smoothly, it means that the size inspection is not a problem. If it cannot slide completely, it means that the substrate 7 is dimensionally defective.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
