Description
Technical Field
[0001] This utility model relates to the field of die casting inspection technology, and in particular to a large-size die casting inspection device. Background Technology
[0002] In modern manufacturing, backlight modules, as a crucial component of display devices, are typically manufactured using metal die casting. With the advancement of display technology, backlight modules are being designed to be increasingly larger; however, large die-cast parts are prone to various defects during production. Due to factors such as the flow characteristics of the molten metal, mold structure, and die-casting process parameters, large die-cast parts may exhibit defects such as shrinkage cavities, deformation, and dimensional deviations. These defects severely affect the product's installation accuracy, leading to problems such as inaccurate installation and poor fit with other components during subsequent assembly, ultimately impacting the performance and quality of the entire display device.
[0003] Traditional inspection methods often struggle to comprehensively and accurately detect defects in large-sized die-cast parts, especially for different shape features (such as through holes, bevels, and curved surfaces). There is a lack of an integrated, efficient, and precise inspection solution. Existing inspection methods often require multiple different devices for separate testing, which is cumbersome, inefficient, and makes it difficult to guarantee the consistency and correlation of results from different devices. Therefore, it is necessary to improve existing technologies to overcome these shortcomings. Utility Model Content

[0013] As a further improvement of this utility model, the hole position detection mechanism includes a movable hole position detection block that matches the through hole of the die casting, the hole position detection block being inserted into the through hole of the die casting for detection.

The inclined surface detection block is slidably mounted on the inclined surface detection base, and the second elastic component is used to apply an elastic force to the inclined surface detection block in the direction opposite to the die casting.
[0018] As a further improvement of this utility model, the arc surface detection block includes an arc surface go gauge detection block and an arc surface no-go gauge detection block. Both the arc surface go gauge detection block and the arc surface no-go gauge detection block are provided with detection heads. The thickness of the detection head of the arc surface go gauge detection block is less than the width of the detection slide, and the thickness of the detection head of the arc surface no-go gauge detection block is greater than the width of the detection slide.
[0019] As a further improvement of this utility model, the hole position detection mechanism, the inclined surface detection mechanism, and the arc surface detection mechanism are each equipped with multiple parts that correspond one-to-one with the hole positions, inclined surfaces, and arc surfaces on the die casting.

[0036] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.
[0037] See Figures 1 to 7 This utility model provides a large-size die-casting part inspection device, including: inspection platform 1, clamping mechanism 3, hole position inspection mechanism 4, inclined surface inspection mechanism 5 and arc surface inspection mechanism 6, the clamping mechanism 3, hole position inspection mechanism 4, inclined surface inspection mechanism 5 and arc surface inspection mechanism 6 are all installed on the inspection platform 1.
[0038] The testing platform 1 is used to place the die-cast part 2 to be tested. It is equipped with multiple support columns, all of which are in contact with the reference surface of the die-cast part 2, providing stable and precise support and positioning for large-sized die-cast parts. The clamping mechanism 3 is located on one side of the support columns and is used to fix the die-cast part 2 placed on the support columns. This effectively prevents the die-cast part 2 from shifting or shaking due to unstable support during the testing process, ensuring the accuracy of subsequent tests and enabling the test results to truly reflect the actual quality condition of the die-cast part 2.
[0039] Furthermore, the hole position detection mechanism 4 is positioned opposite to the through hole of the die casting 2 to detect the through hole of the die casting 2. It can quickly and accurately detect problems such as dimensional deviation and positional offset of the through hole, ensuring that the through hole on the die casting 2 meets the design requirements, thereby ensuring the accuracy of connecting with other components through the hole during subsequent assembly.
[0040] The inclined surface inspection mechanism 5 is positioned opposite to the inclined surface 201 of the die-cast part 2. It is used to inspect the inclined surface 201 of the die-cast part 2. It can effectively detect defects such as angle deviation and flatness of the inclined surface 201. This is crucial for large-sized die-cast parts 2 that require the inclined surface 201 to be installed. It can ensure that the inclined surface 201 can fit tightly with other components during assembly, thereby improving the installation accuracy of the product.
[0041] The arc surface inspection mechanism 6 includes an arc surface measuring reference block 61 and an arc surface inspection block 62. The arc surface measuring reference block 61 has a measuring surface that matches the arc curvature of the die-cast part 2. The gap between the measuring surface of the arc surface measuring reference block 61 and the arc surface of the die-cast part 2 is set as an inspection slide 611. The arc surface inspection block 62 is used to slide along the inspection slide 611 to inspect the arc surface of the die-cast part 2. It can accurately detect defects such as the contour and flatness of the arc surface. This design is specifically designed for the arc surface characteristics of large-size die-cast parts 2, providing an effective means for arc surface quality inspection, ensuring the shape accuracy of the arc surface, and meeting the design and use requirements of the product.
[0042] This utility model's large-size die-casting inspection device integrates a clamping mechanism 3, a hole position detection mechanism 4, an inclined surface detection mechanism 5, and an arc surface detection mechanism 6. It can comprehensively inspect various key shape features on large-size die-casting parts 2 without using multiple different devices for separate inspection, greatly simplifying the inspection process and improving inspection efficiency. At the same time, the various inspection mechanisms work collaboratively within the same device, ensuring the consistency and correlation of results between different inspection items. This helps to comprehensively evaluate the quality of die-casting parts, reduce product defect rates, and ensure the installation accuracy of die-casting parts 2 during assembly.
[0043] In this utility model, the reference surface of the die-cast part 2 includes a Z-direction reference surface and a Y-direction reference surface. The Z-direction reference surface refers to the reference surface facing downwards of the die-cast part 2, while the Y-direction reference surface refers to the reference surface facing backwards of the die-cast part 2.
[0044] See Figures 1 to 3 Correspondingly, the multiple support columns are divided into several first support columns 7 for fitting the Z-direction reference plane and several second support columns 8 for fitting the Y-direction reference plane. The first support columns 7 and the second support columns 8 can not only provide support and positioning for the die-cast part 2, but also detect the Z-direction reference plane and the Y-direction reference plane according to the degree of fitting.
[0045] See Figure 3 and Figure 5 The die-cast part 2 has several mounting feet 21, and the bottom surface of the mounting feet 21 is the reference surface in the Z direction. Each mounting foot 21 is provided with a positioning hole, and each first support column 7 is provided with a positioning post 701. The positioning post 701 cooperates with the positioning hole to further ensure the positioning accuracy of the die-cast part 2.
[0046] In this utility model, the hole position detection mechanism 4 adopts an elbow clamp, specifically a vertical elbow clamp, which is used to press the mounting foot 21 tightly onto the first support column 7.
[0047] See Figure 4, the hole position detection mechanism 4 includes a hole position detection block 41 that is matched with and movable in the through hole of the die-casting part 2, and the hole position detection block 41 is used to insert into the through hole of the die-casting part 2 for detection.
[0048] Specifically, the hole position detection mechanism 4 further includes a hole position detection base 42 fixed to the detection platform 1 through a support plate, a hole position detection mounting block 43 slidably mounted on the hole position detection base 42 through a linear guide rail, and a first elastic member 44 for applying an elastic force in the direction opposite to the die-casting part 2 to the hole position detection mounting block 43. The hole position detection block 41 is fixed to the hole position detection mounting block 43. The first elastic member 44 is a tension spring, one end of which is hooked on the hole position detection mounting block 43, and the other end is hooked on the pin on the hole position detection base 42.
[0049] When detecting the through hole of the die-casting part 2, manually push the hole position detection mounting block 43 to move towards the die-casting part 2. If the hole position detection block 41 can be inserted into the through hole of the die-casting part 2, it indicates that the through hole is qualified; otherwise, it indicates that the through hole has defects. After releasing the hole position detection mounting block 43, the hole position detection mounting block 43 resets under the elastic force of the first elastic member 44.
[0050] Refer to Figure 5 and Figure 6 , the inclined plane detection mechanism 5 includes a movable inclined plane detection block 51, and the inclined plane detection block 51 is provided with an inclined plane detection surface 511 having the same slope as the inclined plane 201 of the die-casting part 2.
[0051] In addition, a go-no-go step 512 is provided at one end of the inclined plane detection surface 511 away from the die-casting part 2. The die-casting part 2 has a stop surface 202 adjacent to the inclined plane 201 and opposite to the go-no-go step 512, and the stop surface 202 is used to stop the go-no-go step 512.
[0052] The inclined plane detection mechanism 5 further includes an inclined plane detection base 52 fixed to the detection platform 1 and a second elastic member 53. The inclined plane detection block 51 is slidably mounted on the inclined plane detection base 52 through a linear guide rail. The second elastic member 53 is also a tension spring, one end of which is hooked on the inclined plane detection block 51, and the other end is hooked on the pin on the inclined plane detection base 52 to apply an elastic force in the direction opposite to the die-casting part 2 to the inclined plane detection block 51.
[0053] When detecting the inclined plane 201 of the die-casting part {2}, manually push the inclined plane detection block 51 to move towards the die-casting part 2. Only when the inclined plane detection surface 511 moves to a position just in contact with the inclined plane 201 or opposite to each other at a small distance, and the go-no-go step 512 stops on the stop surface {202}, it indicates that the inclined plane 201 is qualified; otherwise, it indicates that the inclined plane 201 has defects. After releasing the inclined plane detection block 51, the inclined plane detection block 51 resets under the elastic force of the second elastic member 53.
[0054] See Figure 7 The curved surface inspection block 62 includes a curved surface go gauge inspection block and a curved surface no-go gauge inspection block, both of which are separate components. Both the curved surface go gauge inspection block and the curved surface no-go gauge inspection block are equipped with inspection heads. The thickness of the inspection head of the curved surface go gauge inspection block is less than the width of the inspection slide 611, while the thickness of the inspection head of the curved surface no-go gauge inspection block is greater than the width of the inspection slide 611.
[0055] When inspecting the curved surface of die-cast part 2, first use the curved surface go gauge inspection block, insert its inspection head into the inspection slide 611, and slide it along the inspection slide 611; then use the curved surface no-go gauge inspection block. Since the thickness of the inspection head of the curved surface no-go gauge inspection block is greater than the width of the inspection slide 611, normally the inspection head of the curved surface no-go gauge inspection block cannot be inserted into the inspection slide 611, and can only slide along the outside of the inspection slide 611.
[0056] Since the die-cast part 2 in this embodiment has multiple holes, inclined surfaces 201, and arc surfaces, the hole detection mechanism 4, inclined surface detection mechanism 5, and arc surface detection mechanism 6 in the large-size die-cast part detection device of this utility model are each equipped with multiple holes that correspond one-to-one with the holes, inclined surfaces 201, and arc surfaces on the die-cast part 2.
[0057] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
