Abstract
Description
Technical Field
[0001] The utility model relates to a detection tool, in particular to a flatness detection tool. Background Art
[0002] The company is engaged in the production and manufacturing of servers, optical modules, network cards and other products. Network cards are produced using SMT full-process dedicated carriers. When the carrier is deformed, worn or otherwise abnormal during use, it directly or indirectly affects the production quality and brings about major quality risks. Therefore, it is necessary to quickly and accurately select unqualified carriers, which is a major challenge.
[0003] The current detection method is: the carrier is placed flat on the marble platform, a plug gauge is used to measure the horizontal gap between the marble and the carrier, and a caliper is used to measure the deformation of the carrier side. Due to the operation method and measurement errors, the misjudgment rate of the carrier measurement results is as high as more than 20%, which brings great trouble to production. At the same time, the measurement is time-consuming, and the measurement points cannot be 100% covered. Utility Model Content
[0004] In view of the technical problems that the existing method of detecting carriers has large errors and cannot detect in all directions, the utility model provides a flatness detection tool, which has the advantages of quickly, accurately and comprehensively detecting carriers.
[0005] The technical solution of the utility model is:
[0006] A flatness detection tool, comprising:
[0007] The detection platform is a rectangular parallelepiped structure, with a first detection groove and a second detection groove respectively provided at two ends of its top surface, and a detection through hole provided in the middle of the detection platform in the thickness direction.
[0008] Optionally, the first detection slot and the second detection slot are both in the shape of long strips and are parallel to each other, and the width of the first detection slot is smaller than the width of the second detection slot.
[0009] Optionally, the detection through hole is a rectangular through hole structure, and two ends of the through hole are respectively located on two side surfaces of the detection platform.
[0010] Optionally, a distance between the first detection slot and the second detection slot is greater than a length of the detection through hole.
[0011] Optionally, the four edges of the detection platform in the thickness direction are rounded.
[0012] Optionally, it also includes:
[0013] The base is detachably arranged at the bottom of the detection platform.
[0014] Optionally, the width of the first detection slot is 2.75 mm-2.8 mm.
[0015] Optionally, the width of the second detection slot is 3.2 mm-3.25 mm.
[0016] Optionally, the height of the detection through hole is 9.75mm-9.85mm.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] When inspecting a used vehicle, first inspect the track edge of the vehicle by passing the track edges at both ends of the vehicle through the first inspection groove and the second inspection groove respectively. If it can pass through the first inspection groove or the second inspection groove, it means that the flatness of the track edge of the vehicle meets the requirements; if it cannot pass through both the first inspection groove and the second inspection groove, it does not meet the requirements.
[0019] When testing the flatness of the carrier surface, insert one end of the carrier into one end of the testing hole and continue to push the carrier into the testing hole to observe whether the carrier can completely pass through the testing hole. If it can completely pass through the testing hole, it means that the flatness of the carrier meets the requirements, otherwise it does not meet the requirements.
[0020] Through this technical solution, it is possible to efficiently and accurately determine whether various parameters of the vehicle meet production requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0027] Example:
[0028] See also Figure 1 A flatness detection tool comprises a detection table 1, wherein the detection table 1 is a rectangular parallelepiped structure, and the detection table 1 is placed on a horizontal plane, and its thickness direction is arranged vertically upward. A first detection slot 2 and a second detection slot 3 are arranged on the top surface of the detection table 1, and the first detection slot 2 and the second detection slot 3 are respectively located at two ends of the top surface of the detection table 1, and the first detection slot 2 and the second detection slot 3 are arranged parallel to each other.
[0029] A detection through hole 4 is provided in the middle of the detection platform 1 in the thickness direction, and two ends of the detection through hole 4 pass through two sides of the detection platform 1 respectively.
[0030] Preferably, the first detection slot 2 and the second detection slot 3 are both long strips, and the width of the first detection slot 2 is smaller than the width of the second detection slot 3. In addition, the detection through hole 4 is a rectangular structure, and the distance between the first detection slot 2 and the second detection slot 3 is greater than the length of the detection through hole 4.
[0031] In this embodiment, when inspecting a used carrier, the track edge of the carrier is first inspected by passing the track edges at both ends of the carrier through the first inspection slot 2 and the second inspection slot 3 respectively. If it can pass through the first inspection slot 2 or the second inspection slot 3, it means that the flatness of the track edge of the carrier meets the requirements. If it cannot pass through both the first inspection slot 2 and the second inspection slot 3, it does not meet the requirements.
[0032] When testing the flatness of the carrier surface, one end of the carrier is inserted from one end of the testing through hole 4, and the carrier is continuously pushed into the testing through hole 4 to observe whether the carrier can completely pass through the testing through hole 4. If it can completely pass through the testing through hole 4, it means that the flatness of the carrier meets the requirements, otherwise it does not meet the requirements.
[0033] Through this embodiment, it is possible to efficiently and accurately determine whether various parameters of the carrier meet the production requirements.
[0034] In one specific embodiment:
[0035] The testing platform 1 is made of metal materials such as stainless steel. On the one hand, the hardness of the testing platform 1 is improved to avoid obvious wear during the testing process. On the other hand, the weight of the testing platform 1 is increased so that the carrier does not need to be additionally fixed when passing through the first testing slot 2, the second testing slot 3 and the testing through hole 4.
[0036] Since the testing platform 1 itself is relatively heavy, four edges of the testing platform 1 in the thickness direction are all chamfered to prevent the edges of the testing platform 1 from causing harm to the operator.
[0037] Preferably, a base 5 is detachably provided at the bottom of the testing platform 1 , and the testing platform 1 is supported to a certain height by the base 5 , so as to facilitate the movement of the testing platform 1 .
[0038] In another specific embodiment:
[0039] The carrier tested in this embodiment is a square structure, and its qualified flatness error is within 0.2 mm, and the track thickness on both sides of the carrier is between 2.75 mm and 3.25 mm.
[0040] Therefore, according to the specific size of the carrier, the width of the first detection slot 2 is set to 2.75 mm-2.8 mm, the width of the second detection slot 3 is set to 3.2 mm-3.25 mm, and the height of the detection through hole 4 is set to 9.75 mm-9.85 mm.
[0041] Therefore, when the carrier can fully meet the use requirements, the specific size requirements of the first detection slot 2, the second detection slot 3 and the detection through hole 4 can be met.
[0042] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
