Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone back shell detection, in particular to a mobile phone back shell flatness detection device. Background Art

[0002] The back shell of a mobile phone, also known as the back cover of a mobile phone, is an important component of a mobile phone and is used to protect the electronic components inside the mobile phone. After the production of the mobile phone back shell, in order to ensure the quality of the mobile phone back shell, the flatness of the mobile phone back shell needs to be tested to ensure that it can be assembled into a mobile phone normally.

[0003] As my country's published patent application number CN202122362522.4 relates to a device for detecting the flatness of the back cover of a mobile phone, this technology mentions a means for detecting the flatness of the back cover of a mobile phone, specifically: "A workbench, an L-shaped bracket is provided at one end of the workbench, a laser rangefinder is provided on the top of the L-shaped bracket, a rotating disk is rotatably provided on the workbench, and four through holes for placing the carrier are provided on the rotating disk, and the four through holes are evenly arranged on the rotating disk, and a fixed structure for fixing the carrier is provided on the workbench directly below the laser rangefinder, and a limiting mechanism for limiting the stopping of the rotating disk is provided between the rotating disk and the L-shaped bracket on one side of the fixed structure.

The top of the rotating disk 2 is also provided with a plurality of positioning grooves 3. The inner wall of the positioning groove 3 is provided with clamping blocks 302. One side of the clamping block 302 is movably connected to the movable groove 301 opened inside the rotating disk 2. The inner wall of the movable groove 301 is equidistantly fixed with extrusion springs 303. The other end of the extrusion spring 303 is fixed on the clamping block 302. It also includes a mobile phone back shell body 16. The mobile phone back shell body 16 is placed in the positioning groove 3 and is fixed by the two clamping blocks 302 in the positioning groove 3. By arranging the clamping blocks 302 in the positioning groove 3, the mobile phone back shell body 16 placed in the positioning groove 3 can be stably clamped, thereby ensuring the stability of the mobile phone back shell body 16 in the positioning groove 3. , to ensure the normal progress of the detection work; a support frame 4 is also fixed to the top back of the support platform 1, and a detection component 8 connected by an adjustment component is provided on the top of the support frame 4. The detection component 8 includes a fixed frame 801, a resistance rod 802, a fixed plate 1 803 and a fixed plate 2 804. There are multiple resistance rods 802 and they are evenly distributed at the bottom of the fixed frame 801. The fixed frame 801 and the resistance rod 802 are both made of plastic. The plastic fixed frame 801 and the resistance rod 802 can avoid conductivity, thereby ensuring safety during the detection process. The top of the resistance rod 802 is movable through the interior of the fixed frame 801 and is fixed with a contact rod 8021; a battery 5 and an indicator light 6 are also installed on the top of the support frame 4; the fixed plate 2 804 and the contact rod 8021 are both made of conductive metal, and the fixed plate 2 804 is electrically connected to the battery 5 through a wire. The fixed plate 2 804 and the contact rod 8021 made of conductive metal can realize circuit communication between the contact rod 8021 and the fixed plate 2 804.

[0028] In this embodiment, the adjustment assembly includes an adjusting screw 7 and a limiting rod 10. The adjusting screw 7 is threaded through the support frame 4 and is rotatably connected to the top of the fixed frame 801. There are two limiting rods 10, and the bottom of each limiting rod 10 is movable through the support frame 4 and fixed to the top of the fixed frame 801.

[0029] Specifically, through the set adjustment component, the height of the fixed frame 801 can be adjusted at will to adapt to mobile phone back shell bodies 16 of different thicknesses, and can realize the detection of mobile phone back shell bodies 16 of different thicknesses. The limit rod 10 designed in conjunction with it can improve the stability of the fixed frame 801 during movement.

[0030] In this embodiment, a cavity 13 is provided inside the fixed plate 804 and at a position corresponding to each contact rod 8021. A reset spring 14 is provided inside the cavity 13 and is sleeved on the surface of the contact rod 8021. The top of the contact rod 8021 moves through the cavity 13 to the top of the fixed plate 804. A push plate 15 is also fixedly sleeved on the rod body of the contact rod 8021 located inside the cavity 13, and the bottom of the reset spring 14 is fixed to the top of the push plate 15.

[0031] Specifically, through the designed return spring 14 and push plate 15, the thrust of the return spring 14 can be used to prevent the contact rod 8021 from always contacting the groove 8031, thereby ensuring the stability of the contact rod 8021. Only when the contact rod 8021 is pushed upward can the contact rod 8021 and the groove 8031 ​​be in contact.

[0032] In this embodiment, a groove 8031 ​​is provided at the bottom of the fixing plate 803 and at a position corresponding to each contact rod 8021. The groove 8031 ​​is close to the top of the contact rod 8021. The fixing plate 803 is made of conductive metal and is electrically connected to the indicator light 6 through a wire.

[0033] Specifically, the fixing plate 803 is made of conductive metal and can achieve electrical conductivity. That is, when the conductive contact rod 8021 contacts the fixing plate 803, the circuit between the indicator light 6 and the battery 5 can be connected, and the indicator light 6 can be turned on.

[0034] In this embodiment, a circular limiting slider 12 is fixed to the bottom of the rotating disk 2 , and a circular limiting slot 11 is provided on the top of the supporting platform 1 , in which the limiting slider 12 is slidably connected.

[0035] Specifically, by providing a limiting slider 12 at the bottom of the rotating disk 2 and opening a limiting slot 11 at the top of the support platform 1, the stability of the rotating disk 2 during rotation can be improved, and the normal execution of the detection work can be ensured.

[0036] During use: the staff can first place a standard and qualified mobile phone rear shell body 16 in the positioning groove 3, and rotate the rotating disk 2 to make the qualified mobile phone rear shell body 16 come to the bottom of the fixed frame 801, and then use the adjustment component to adjust the height position of the fixed frame 801 so that the bottoms of the multiple interference rods 802 fit the top of the mobile phone rear shell body 16. When adjusting, screw the adjusting screw 7, and the adjusting screw 7 rotates to push the fixed frame 801 down. When the bottoms of the interference rods 802 fit the top of the mobile phone rear shell body 16, stop rotating the adjusting screw 7. At this time, the height adjustment of the fixed frame 801 can be completed to determine the distance between the qualified mobile phone rear shell body 16 and the fixed frame 801, thereby facilitating the judgment of the mobile phone rear shell body 16 to be tested subsequently.

[0037] The staff first takes out the qualified mobile phone back shell body 16 mentioned above from the positioning groove 3, and then places the mobile phone back shell body 16 to be tested into the multiple positioning grooves 3 in sequence (so that the bottom of the mobile phone back shell body 16 fits in the bottom of the positioning groove 3). When placing, the two sides of the mobile phone back shell body 16 squeeze the clamping blocks 302 in the positioning groove 3, and then the clamping blocks 302 push the extrusion spring 303 to compress, so that the mobile phone back shell body 16 is clamped by the two clamping blocks 302, so that the mobile phone back shell body 16 is stable in the positioning groove 3;

[0038] Start the servo motor 9, and the power output shaft of the servo motor 9 drives the rotating disk 2 to rotate at a constant speed. When the rotating disk 2 rotates, the mobile phone rear shell body 16 in the multiple positioning grooves 3 is sequentially transported to the bottom of the fixed frame 801. When the mobile phone rear shell body 16 to be detected passes the bottom of the fixed frame 801, if the top surface of the mobile phone rear shell body 16 is not flat (local bulges, bends, etc.), the uneven part of the mobile phone rear shell body 16 will contact the resistance rod 802, thereby pushing the resistance rod 802 upward. When the resistance rod 802 moves upward, it can synchronously drive the contact rod 8021 to rise, so that the contact rod 8021 contacts the groove 8031 ​​of the fixed plate 803. When the contact rod 802 moves upward, it can synchronously drive the contact rod 8021 to rise, so that the contact rod 8021 contacts the groove 8031 ​​of the fixed plate 803. When 021 contacts the fixing plate 1 803, the circuit between the fixing plate 1 803 and the fixing plate 2 804 is connected, and the indicator light 6 will emit light, thereby intuitively reminding the staff that the mobile phone rear shell body 16 is a defective product. On the contrary, when the mobile phone rear shell body 16 in the positioning groove 3 is flat, it will not affect the interference rod 802, thereby failing to connect the circuit between the fixing plate 1 803 and the fixing plate 2 804, thereby intuitively reminding the staff that the mobile phone rear shell body 16 is a qualified product. In order to ensure the accuracy of the detection, the staff can rotate the rotating disk 2 for multiple circles, thereby realizing multiple detection of the mobile phone rear shell body 16 in the positioning groove 3 to ensure the accuracy of the detection result.

[0039] When the inspection of a group of mobile phone back shell bodies 16 is completed, the staff can remove multiple mobile phone back shell bodies 16 in the positioning groove 3 of the rotating disk 2, classify and store qualified products and unqualified products, and install new mobile phone back shell bodies 16 to be inspected, so as to realize the cycle of inspection work.

[0040] It should be noted that the device can detect mobile phone back shell bodies 16 of different thicknesses by adjusting the height of the fixing frame 801, thereby improving the applicability of the device, and when conducting specific inspections on the same batch of mobile phone back shell bodies 16, it is only necessary to adjust the height of the fixing frame 801 once, and the operation steps are few. The staff only needs to install and remove the mobile phone back shell body 16 on the rotating disk 2 to intuitively see whether the inspected mobile phone back shell body 16 is qualified. This method is simpler and more convenient than the existing technology, and has higher inspection efficiency.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
