Description
Technical Field
The utility model relates to the field of electronic device processing tools, in particular to a quick gauge-type Sic module pin tooth substrate appearance gauge.
Background
Because the density of the needle teeth is higher, the overall dimension of a single needle tooth is smaller, and the needle teeth can only be cut at break points in the machining process, so that the needle teeth are easy to bend and deform. The plating edge effect also affects the overall dimensions of the product. If the two-dimensional scanning is adopted, the recognition cost is high, the time is long, and the operator cannot judge in time on line. Meanwhile, the needle tooth substrate of the vehicle gauge SiC module has higher limit requirement on external dimension in the subsequent packaging process, and if the needle tooth distribution and the external dimension of the substrate are not in accordance with the requirements, assembly interference can be caused. Therefore, a rapid inspection tool is highly needed in the production process to determine whether the pin tooth distribution and the external dimension of the substrate meet the technical requirements.
Disclosure of Invention
In order to solve the problems in the prior art, the utility model provides the quick gauge SiC module pin tooth substrate appearance detection tool which can be used for simultaneously and quickly detecting pin tooth distribution and appearance size of the SiC module pin tooth substrate, and has the advantages of high detection efficiency, low cost, rapidness and convenience.
The technical scheme adopted in the utility model is as follows:
the utility model provides a quick gauge needle tooth base plate appearance of car rule level SiC module, includes examines a board, it has the base plate spacing groove to examine to open on the board for place to wait to examine the base plate, it is equipped with a plurality of needle tooth spacing holes on the board to examine for pass the needle tooth on waiting to examine the base plate, the spacing inslot of needle tooth spacing hole.
Preferably, the plurality of pin tooth limiting holes are distributed according to the pin teeth of the base plate.
Preferably, the substrate limiting groove is arranged according to the shape of the substrate to be tested.
Preferably, the gauge plate is further provided with two handle grooves respectively for placing and taking the substrate to be inspected, the two handle grooves are respectively located at two sides of the substrate limiting groove, and the handle grooves are communicated with the substrate limiting groove.
Preferably, the substrate limiting groove is a square groove.
The beneficial effects are that: the utility model provides a quick gauge SiC module pin tooth substrate appearance checking fixture, which can detect the appearance and pin teeth of a substrate through a substrate limiting groove and a pin tooth limiting hole on the checking fixture, greatly improves the detection efficiency, can intuitively detect whether the substrate meets the technical requirements, reduces the detection cost and is favorable for finding the substrate problem in time.
Drawings
Fig. 1 is a schematic diagram of the structure of the test tool in embodiment 1.
In the figure: gauge plate 1, base plate spacing groove 2, needle tooth spacing hole 3, handle groove 4.
Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. The following description of the embodiments is merely exemplary in nature and it is to be understood that the embodiments described herein are merely illustrative of the utility model, and are in no way intended to limit the utility model, its application, or uses.
Example 1:
as shown in fig. 1, the quick gauge-grade SiC module needle tooth substrate appearance gauge comprises a gauge plate 1, wherein a substrate limiting groove 2 is formed in the gauge plate 1 and used for placing a substrate to be detected, a plurality of needle tooth limiting holes 3 are formed in the gauge plate 1 and used for penetrating needle teeth on the substrate to be detected, and the needle tooth limiting holes 3 are located in the limiting groove. The gauge plate 1 is also provided with two handle grooves 4 respectively for placing and taking the substrate to be inspected, the two handle grooves 4 are respectively positioned at two sides of the substrate limiting groove 2, and the handle grooves 4 are communicated with the substrate limiting groove 2. In this embodiment 1, the substrate limiting groove 2 is a square groove.
In the utility model, the pin tooth limiting holes 3 are distributed according to the pin teeth of the substrate to be tested. The substrate limiting groove 2 is arranged according to the shape of the substrate to be tested.
The working principle of the utility model is as follows:
the gauge plate is designed according to the actual shape of the substrate to be measured and the distribution of the needle teeth of the substrate, and then the substrate to be measured is only required to be placed at the detection position of the gauge plate, and whether the substrate to be measured can be placed in the substrate limiting groove 2 and the needle teeth limiting holes 3 is judged. If the appearance of the substrate is problematic due to the plating edge effect, the substrate limit groove 3 in the gauge plate is not met. If the substrate needle teeth cannot bend, the substrate needle teeth cannot be inserted into the needle teeth limiting holes 3. Aiming at the defects, the staff can quickly identify the defects by naked eyes by using the gauge plate, so that the detection efficiency is greatly improved, and meanwhile, the detection cost is reduced.
Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
