All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0017] In the description of this utility model, it should be noted that all terms used in this utility model (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains, and should not be construed as limiting this utility model; it should be further understood that the terms used in this utility model should be understood to have the same meaning as those in the context of this specification and in the relevant field, and should not be understood in an idealized or overly formal sense, except as expressly defined in this utility model.
[0018] This utility model provides a convenient MLCC measurement device, such as... Figure 1 As shown, the assembly includes a base plate 10, a dial indicator 20, a head fixing fixture 30, a measuring component 40, and a fixing component 50. The upper surface of the base plate 10 is inclined at a preset angle. The dial indicator 20, head fixing fixture 30, measuring component 40, and fixing component 50 are sequentially mounted on the inclined upper surface of the base plate 10 from top to bottom. Preferably, the inclination angle between the upper surface of the base plate 10 and the horizontal plane is between 30° and 45°. The inclination angle is set so that when the MLCC is fixed to the fixing component 50, the dial indicator 20 and the measuring component 40 will slide downwards due to gravity and come into contact with the MLCC, thereby measuring the width data of the MLCC. Specifically, the length, width, and height of the MLCC can all be measured.
[0019] In one embodiment, the meter head fixing fixture 30 has a through hole 31, through which the measuring rod 21 of the dial indicator 20 passes and abuts against the measuring component 40. Specifically, the meter head fixing fixture 30 is fixed to the base plate 10 by screws, and the measuring rod 21 of the dial indicator 20 passes through the through hole 31 of the meter head fixing fixture 30. The meter head fixing fixture 30 serves a fixing function and abuts against the measuring component 40, measuring the MLCC according to the sliding distance of the measuring component 40.
[0020] In one embodiment, the measuring assembly 40 includes a linear guide rail 41 and a measuring fixture 42. The linear guide rail 41 is fixed to the upper surface of the base plate 10, and the measuring fixture 42 is fixed to the surface of the linear guide rail 41. Specifically, the linear guide rail 41 serves a guiding function and is fixed to the base plate 10 to guide the vertical direction and position of the base plate 10 and the measuring fixture 42. The measuring fixture 42 includes a sliding block 421 and an abutment rod 422 fixed to the lower end of the sliding block 421; during measurement, the abutment rod 422 abuts against the upper end surface of the MLCC.
[0021] In one embodiment, the fixing component 50 includes a guide block and a limiting block 51. The guide block includes a first guide block 52 and a second guide block 53, which are disposed at the same height on the upper surface of the base plate 10. The limiting block 51 is installed at the bottom end of the first guide block 52 and the second guide block 53. A predetermined gap of width is spaced between the first guide block 52 and the second guide block 53. The limiting block 51 blocks the bottom of the gap, and a receiving space 54 is formed between the gap between the first guide block 52 and the second guide block 53 and the limiting block 51 to fix the MLCC. Specifically, the guide block serves as a guide and limiting element, is fixed to the linear guide rail 41, and is used for auxiliary vertical limiting during product measurement.
[0022] Furthermore, those skilled in the art should understand that although many problems exist in the prior art, each embodiment or technical solution of this utility model can be improved in only one or a few aspects, without necessarily solving all the technical problems listed in the prior art or background art simultaneously. Those skilled in the art should understand that any content not mentioned in a claim should not be construed as a limitation on that claim.
