[0002] Plate-like structures, such as mobile phone and tablet casings, are crucial internal support structures. Their flatness plays a crucial role in subsequent assembly and component installation. Therefore, after manufacturing, these casings must be tested for flatness. Conventional flatness testing often relies on a meter. This involves securing the product to a standard surface with a fixture and then measuring point by point or along several straight lines along the surface using a micrometer.

[0003] The above technology has the following technical problems: when the flatness of the mobile phone case or tablet case is manually inspected, there are technical problems such as low inspection efficiency and low inspection accuracy; in addition, since the mobile phone case and tablet case are relatively thin, it is not easy to fix them on the existing mechanical fixture, and it is easy to cause the mobile phone case and tablet case to deform, making it impossible to effectively inspect their flatness.

[0004] The low efficiency makes the flatness detection of mobile phone mid-plates take a long time. Based on this, the applicant proposes a mobile phone mid-plate flatness detection tool with high detection efficiency. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. Example

[0026] See attached Figure 1 、 2As shown, a flatness detection auxiliary tooling includes a base 1, a frame 2 is fixedly connected to the base 1 by bolts, an X-direction slide module 3 is fixedly mounted on the frame 2 along the X direction, a Z-direction slide module 4 is fixedly connected to the moving part of the X-direction slide module 2 along the Z direction, and a Y-direction slide module 5 is fixedly mounted on the upper end surface of the base 1 below the Z-direction slide module 4 along the Y direction by bolts. It should be noted that the X-direction, Y-direction and Z-direction can be referred to Figure 1 In the coordinate system, the X-direction is the lengthwise direction of the X-direction slide module 3, the Z-direction is the vertical direction perpendicular to the X-direction, and the Y-direction is the horizontal direction perpendicular to the X-direction. The X-direction slide module 3, the Z-direction slide module 4, and the Y-direction slide module 5 can all be linear modules driven by existing servo motors and screws. The moving parts of the X-direction slide module 3, the Z-direction slide module 4, and the Y-direction slide module 5 mentioned above and below refer to the sliders engaged on the screws.

[0027] See also Figure 3 、 4 As shown, a mounting frame 6 is fixedly connected to the moving part of the Z-axis slide module 4 by bolts, and a plurality of digital dial indicators 7 are vertically fixedly embedded in the mounting frame 6. The mounting frame 6 includes a vertical plate 61 fixedly connected to the moving part of the Z-axis slide module 4 by bolts and a horizontal plate 62 fixedly connected horizontally to the vertical plate 61 by bolts, and the digital dial indicators 7 are fixedly embedded in the horizontal plate 62. It should be noted that the digital dial indicators 7 can use existing digital dial indicators with digital display functions and the ability to export test data, so as to facilitate rapid analysis and acquisition of test data. Of course, through the digital display function, an operator can also manually detect the test data of each digital dial indicator 7 and manually analyze the flatness data.

[0028] Furthermore, to facilitate installation and adjustment of the digital dial indicator 7, a mounting plate 63 is fixedly connected to the horizontal plate 62. The mounting plate 63 is provided with mounting through-holes 631, the number of which matches the number of the digital dial indicator 7, and a mounting through-slot 632, one end of which communicates with the mounting through-holes 631 and the other end of which extends to a vertical end surface of one side of the mounting plate 63. That is, the mounting through-slot 632 is an L-shaped structure, communicating with the mounting through-holes 631 and penetrating the vertical end surface of the mounting plate 63. The digital dial indicator 7 is fixedly embedded in the mounting through-holes 631. Fastening bolts 64 are horizontally inserted into the mounting through-slot 632 and threadedly connected to the mounting plate 63. The fastening bolts 64 squeeze the mounting plate 63 on both sides of the mounting through-slot 632, thereby securing the digital dial indicator 7 in the mounting through-holes 631.

[0029] In order to facilitate fine adjustment of the mounting plate 63 , waist-shaped connecting holes 633 are opened at both ends of the mounting plate 63 along its length direction. Connecting bolts (not shown in the figure) are passed through the connecting holes 633 and threadedly connected to the horizontal plate 62 .

[0030] See also Figure 5 、 6 As shown, the Y-axis slide module 5 is fixedly connected to the base 1 below the digital micrometer 7. A support plate 51 is horizontally fixedly connected to the moving part of the Y-axis slide module 5 via bolts. An air suction plate 8 with an internal hollow structure is fixedly mounted on the support plate 51. A plurality of air suction holes 81 are formed in the upper end surface of the air suction plate 8. The inner cavity of the air suction plate 81 is connected to a vacuum generator (not shown). In this embodiment, an existing vacuum generator and air storage tank can be selected. The operating principle is based on the existing technology, that is, the vacuum generator removes air from the inner cavity of the air suction plate 8 to adsorb the product 9 on the air suction plate 8. When the vacuum generator stops working, air re-enters the inner cavity of the air suction plate 8 to remove the product 9. To improve the adsorption capacity and uniformity of the product 9, the upper end surface of the air suction plate 8 is provided with a crisscross pattern of interconnected air suction grooves 82. The air suction grooves 82 are connected to the inner cavity of the air suction plate 8 through the air suction holes 81.

[0031] To accurately position the product 9, the structure and dimensions of the air suction plate 8 are adapted to the shape of the product 9. Furthermore, positioning posts 511 are vertically embedded in the support plate 51 outside the air suction plate 8 to facilitate positioning of the product 9. To prevent the positioning posts 511 from damaging the product 9, anti-collision rubber sleeves 512 are provided over the positioning posts 511.

[0032] In order to facilitate the taking and placing of the product 9 on the air suction plate 8, a taking and placing groove 83 is opened on both sides of the air suction plate 8. The taking and placing groove 83 is arranged on the inner side of the product 9, that is, the edge of the product 9 extends to the outer side of the taking and placing groove 83.

[0033] See also Figure 1 As shown, in order to improve the detection efficiency, two Y-axis slide modules 5 are arranged parallel to each other on the base 1, and each Y-axis slide module 5 is correspondingly provided with a support plate 51, an air suction plate 8 and a positioning column 511 of the above structure.

[0034] The working process of the embodiment of the utility model is as follows:

[0035] See Figure 1As shown, a product 9 is placed on the right air suction plate 8 so that it is inside the positioning column 511, and the vacuum generating device is started to fix the product 9 on the air suction plate 8. The controller controls the Y-axis slide module 5 to drive the corresponding air suction plate 8 and product 9 to move forward; the X-axis slide module 3 drives the Z-axis slide module 4, the mounting frame 6 and the digital display micrometer 7 to move above the product 9, and the Z-axis slide module 4 drives the mounting frame 6 and the digital display micrometer 7 to move downward, so that the digital display micrometer 7 contacts the corresponding position of the product 9 and performs a flatness detection on it, and the detection results can be uploaded to the controller and for display; during the inspection of the right product 9, the operator can place the left product 9 on the air suction plate 8 on the left Y-axis slide module; after the inspection of the right product 9 is completed, the Z-axis slide module 4 drives the digital micrometer 7 to rise, the right Y-axis slide module 5 moves backward to facilitate the operator to remove the right product 9, the left Y-axis slide module 5 drives the left product 9 to move forward, and the X-axis slide module 3 drives the digital micrometer 7 to move above the left product 9, and performs flatness inspection on the left product 9, and repeats the cycle to realize the flatness inspection of batch products 9.

[0036] It should be noted that the controller can use an existing PLLC controller. Its connection method and control principle with the X-axis slide module 3, the Z-axis slide module 4, the Y-axis slide module 5, the vacuum generating device, etc. are existing technologies and will not be repeated here. It is set up to improve the level of automation, as long as it can meet the above-mentioned working process.
