Abstract
Description
Technical Field
[0001] The present application relates to the technical field of printing detection jigs, and in particular to a single-piece printing offset measurement jig. Background Art
[0002] In the semiconductor field, the surface of the substrate is colloid, and a laser machine is often needed to engrave the customer's trademark, model and related factory product production information on it.
[0003] After the product is laser engraved, the laser engraved information needs to be tested to determine whether the printing of the laser engraved product is qualified. During the test, the product needs to be placed under a microscope for comparison and analysis. In the actual test process, each product needs to be compared, resulting in qualified products also needing to be tested at least once, which will prolong the test time and affect efficiency. Utility Model Content
[0004] In order to facilitate the detection of offset and improve work efficiency, the present application provides a single-piece printing offset measurement fixture.
[0005] The present application provides a single-piece printing offset measurement jig, which adopts the following technical solution: a single-piece printing offset measurement jig, comprising a base, the base having a measuring groove for an object to be detected to be embedded, a transparent plate for covering the measuring groove being detachably connected to the base, the transparent plate having offset scale lines corresponding to the object to be detected, two extension grooves being formed on the side walls of the measuring groove for removing the object to be detected, and the transparent plate having a fixing block plugged into the base.
[0006] By adopting the above technical solution, before detection, the object to be detected is placed on the base through the measuring groove, and then the object to be detected is covered by a transparent plate. The transparent plate is different according to the different objects to be detected, so that the corresponding offset scale line can be compared with the printing on the object to be detected. If they are completely consistent, there is no need for subsequent detection. In the case of an offset, an overall comparison can obtain a specific offset, which is convenient for the subsequent classification of good and defective products, thereby improving work efficiency.

[0008] Preferably, the base is provided with a slot for the fixing block to be inserted into.
[0009] Preferably, two fixing blocks are provided, and the widths of the two fixing blocks are different.
[0010] Preferably, the inner wall of the slot is provided with a deformable protrusion, and the fixing block is provided with a corresponding limiting groove for the deformable protrusion to be embedded.
[0011] Preferably, the inner wall of the slot is recessed to form an avoidance groove, and the deformation protrusion includes a structural rod connected in parallel to the bottom of the avoidance groove, and an arc-shaped convex ring connected between the two structural rods, and the top of the arc-shaped convex ring is used to be embedded in the limiting groove.
[0012] Preferably, the distance between the ends of the two structural rods connected to the inner wall of the avoidance groove and the other ends gradually increases.
[0013] Preferably, an auxiliary spring is provided between the bottom wall of the avoidance groove and the concave side of the arc-shaped convex ring.
[0014] Preferably, the end of the structural rod is located in the avoidance groove, and the top of the arc-shaped convex ring is exposed outside the avoidance groove.
[0015] Preferably, the transparent plate is made of acrylic material.
[0016] In summary, the present application includes at least one of the following beneficial technical effects:
[0017] 1. By cooperating with the transparent plate on the base, the objects to be tested can be compared. If there is no deviation, the test is omitted. For the part with deviation, the whole part is tested, which is convenient for the subsequent classification of good and defective products and improves work efficiency.
[0018] 2. The transparent plate can achieve the effect of anti-fool through the difference of notches or fixed blocks;
[0019] 3. The transparent plate is fixed and reinforced by an arc-shaped convex ring, so that the offset scale line can be accurately compared with the object to be detected, thereby improving the comparison accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present application is further described in detail below in conjunction with the accompanying drawings. Example
[0026] Embodiment 1 of the present application discloses a single-piece measuring printing offset jig, referring to Figure 1 , including a base 100, the base 100 has a measuring slot 110 for the object to be measured to be embedded, and a transparent plate 111 for covering the measuring slot 110 is detachably connected to the base 100, and the transparent plate 111 has offset scale lines corresponding to the object to be measured. In this embodiment, the offset scale lines are cross-shaped and can be set on the transparent plate 111 by, for example, a sticker. In other embodiments, they can also be framed scale lines or other graphics, and the specific setting depends on the corresponding object to be measured.
[0027] The side wall of the measuring groove 110 is extended to form two extension grooves 112. When the object to be measured is placed in the measuring groove 110, the extension grooves 112 on both sides can be extended into a clamp, such as a clamp that can clamp both sides of the object to be measured, for taking out the object to be measured.
[0028] The transparent plate 111 has a fixing block 114 plugged into the base 100. Correspondingly, the base 100 also has a slot 115 for the fixing block 114 to be inserted into, so as to cover the transparent plate 111 on the base 100. The transparent plate 111 in this embodiment is made of an acrylic plate.
[0029] In order to prevent the base 100 and the transparent plate 111 from being reversed, the transparent plate 111 and the base 100 are both rectangular, and the transparent plate 111 and the base 100 have the same notch 113 at the same corner. In this way, when closing, the two corners need to be aligned before the fixing block 114 is inserted, which plays a fool-proof role.
[0030] At the same time, different transparent plates 111 can be covered according to different objects to be measured, and the adaptability is strong.
[0031] The specific measurement process of Example 1 is as follows: first, the object to be measured is placed into the measuring slot 110, and before covering the transparent plate 111, the two notches 113 are aligned, and the fixing block 114 is inserted into the slot 115. At this time, the offset scale line is compared with the printing, and products with excessive offset will be defined as defective products, which will improve work efficiency overall. Example
[0032] The difference from Example 1 is that, referring to Figure 2 , Figure 3, the widths of the fixing blocks 114 are set to be different, so that when inserting, the fixing blocks 114 that do not correspond to each other cannot be inserted, which further plays a foolproof role. And in order to increase the stability of the transparent plate 111 fixed on the base 100. In this embodiment, the inner wall of the slot 115 is provided with a deformable protrusion, and the fixing block 114 is provided with a corresponding limit groove 120 for the deformation protrusion to be embedded.
[0033] Specifically, refer to Figure 3 , Figure 4 The inner wall of the slot 115 is recessed to form an avoidance groove 121, and the deformation protrusion includes a structural rod 122 connected in parallel to the bottom of the avoidance groove 121, and an arc-shaped convex ring 123 connected between the two structural rods 122, and the top of the arc-shaped convex ring 123 is used to be embedded in the limit groove 120. The distance between the ends of the two structural rods 122 connected to the inner wall of the avoidance groove 121 and the other end gradually increases. That is, the two structural rods 122 are inclined, and their inclination angle is convenient for deformation.
[0034] It is worth noting that, in terms of depth, the top of the arc-shaped convex ring 123 will protrude outward from the avoidance groove 121, and the end of the structural rod 122 will always remain in the avoidance groove 121 during the deformation process, so that when the fixing block 114 slides down and is embedded in the slot 115, the arc-shaped convex ring 123 will be deformed and embedded in the limit groove 120.
[0035] In order to ensure the continuous deformation ability of the arc-shaped convex ring 123, in this embodiment, an auxiliary spring 124 is provided between the bottom wall of the avoidance groove 121 and the concave side of the arc-shaped convex ring 123. The expansion and contraction of the auxiliary spring 124 can assist the arc-shaped convex ring 123 to move back and forth. At the same time, the auxiliary spring 124 can form a supporting force in a direction perpendicular to the bottom wall to prevent the deformation protrusion from being skewed as a whole.
[0036] The specific measurement process of Example 2 is as follows: when the transparent plate 111 is covered on the base 100, during the embedding process of the fixing block 114, the arc-shaped convex ring 123 contacts the inner wall and deforms, the structural rod 122 expands outward, and the auxiliary spring 124 is compressed until the fixing block 114 is completely embedded in the slot 115. After the arc-shaped convex ring 123 and the auxiliary spring 124 are restored, the top of the arc-shaped convex ring 123 will be embedded in the limiting groove 120.
[0037] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
