Description

Technical Field

[0002] In the process of mobile phone manufacturing, in order to avoid safety accidents caused by foreign objects such as screws puncturing the battery during battery pressure holding, resulting in fire and explosion, it is necessary to clean the battery compartment of the mobile phone frame before battery assembly.

[0003] Among them, the Chinese utility model patent with patent number ZL202320094086.3 and patent name: A barcode-scanning screw adsorption device, substantially discloses a foreign object cleaning device for the battery compartment of a mobile phone frame before battery assembly; the barcode-scanning screw adsorption device discloses the following technical solution, specifically: a barcode-scanning screw adsorption device, including a main base and a barcode scanning component, the upper surface of the main base is equipped with a product positioning fixture; the product positioning fixture includes a fixture support plate, the upper surface of the fixture support plate is provided with a product placement area, and product positioning blocks are provided on the upper surface of the fixture support plate around the product placement area; a battery conforming cover is installed on the product support plate in the product placement area, and a magnet is installed inside the battery conforming cover; the product support plate has a support plate through hole located next to the battery conforming cover in the product placement area, and the barcode scanning component is located below the product support plate and aligned with the support plate through hole. When the barcode scanning screw adsorption device is working, the battery conformal cover is aligned and inserted into the battery compartment of the phone when the phone frame before battery assembly is positioned in the product placement area of ​​the fixture support plate. Since the inside of the battery conformal cover is equipped with a magnet, if there is a missing screw in the battery compartment before battery assembly, the magnet can attract the screw in the phone. When the staff removes the phone frame from the product placement area, the screw is attracted to the battery conformal cover. This can avoid the battery being damaged or even exploded due to the screw in the battery compartment being installed directly without checking. It can also save the process of having staff visually check whether there are screws in the battery compartment.

[0004] It should be noted that the above-mentioned barcode scanning screw adsorption equipment has the following defects: the barcode scanning screw adsorption equipment requires manual loading and unloading of mobile phone frames, resulting in low automation and low work efficiency.

Detailed Implementation

[0021] The present invention will now be described in conjunction with specific embodiments.

[0022] Example 1, as Figures 1 to 3 As shown, an automatic screw adsorption device for mobile phone frames includes a fixed base 1 and a screw adsorption assembly 2 installed on the fixed base 1. The fixed base 1 is provided with a front support plate 11 and a rear support plate 12 arranged vertically. The front support plate 11 and the rear support plate 12 are arranged opposite each other and spaced apart. A movable flipping table 3 is installed between the front support plate 11 and the rear support plate 12. The movable flipping table 3 is equipped with a mobile phone frame conveyor belt 4 for conveying the mobile phone frame from front to back. The mobile phone frame conveyor belt 4 is equipped with a mobile phone frame adsorption mechanism 5.

[0023] Among them, such as Figures 1 to 4 As shown, the fixed base 1 is equipped with a rotating table drive mechanism 6 corresponding to the movable rotating table 3, and the rotating table drive mechanism 6 is drivenly connected to the movable rotating table 3.

[0024] Furthermore, such as Figure 1 and Figure 3 As shown, the screw adsorption assembly 2 includes a lifting frame 21 located below the mobile phone frame conveyor belt 4, and the lifting frame 21 is equipped with a permanent magnet 22; the fixed base 1 is equipped with a lifting drive mechanism 23 corresponding to the lifting frame 21, and the lifting drive mechanism 23 is drivenly connected to the lifting frame 21.

[0025] It should be noted that the automatic screw-adsorption device for mobile phone frames in this embodiment is equipped with a controller. The mobile phone frame conveyor belt 4, the mobile phone frame adsorption mechanism 5, the flip table drive mechanism 6, and the lifting drive mechanism 23 are electrically connected to the controller. During operation, the controller controls the operation of the mobile phone frame conveyor belt 4, the mobile phone frame adsorption mechanism 5, the flip table drive mechanism 6, and the lifting drive mechanism 23 respectively.

[0026] The process of using the automatic screw-adhesive device for mobile phone frames in this embodiment to perform screw-adhesive operations includes the following steps: Step a: The phone frame is placed on the phone frame conveyor belt 4. The phone frame conveyor belt 4 transports the phone frame backward and makes the phone frame reach the position of the phone frame adsorption mechanism 5. Step b: After the phone frame reaches the position of the phone frame adsorption mechanism 5, the phone frame conveyor belt 4 stops moving, and the phone frame adsorption mechanism 5 adsorbs and fixes the phone frame. Step c: After the phone frame adsorption mechanism 5 adsorbs and fixes the phone frame, the flip table drive mechanism 6 is activated and drives the movable flip table 3 to rotate 180 degrees. The phone frame conveyor belt 4, the phone frame adsorption mechanism 5, and the adsorbed and fixed phone frame rotate 180 degrees synchronously with the movable flip table 3, so that the adsorbed and fixed phone frame flips downward. Step d: After the active flipping platform 3 flips into place, the lifting drive mechanism 23 is activated and drives the lifting active frame 21 and the permanent magnet 22 to move upward synchronously, so that the permanent magnet 22 is close to the mobile phone frame that is attracted and fixed, thereby attracting the screws stuck on the mobile phone frame. Step e: After the permanent magnet 22 moves upward and completes screw adsorption, the lifting drive mechanism 23 drives the lifting movable frame 21 and the permanent magnet 22 to move downward and reset to the initial position. Step f: After the lifting drive mechanism 23 drives the lifting movable frame 21 and permanent magnet 22 to move down and reset, the tilting table drive mechanism 6 is activated and drives the movable tilting table 3 to rotate 180 degrees in the opposite direction, thereby causing the movable tilting table 3 and the mobile phone frame conveyor belt 4 to reset to their initial positions. Step g: The mobile phone frame conveyor belt 4 moves and sends out the mobile phone frame after the screws have been attracted.

[0027] It should be emphasized that the automatic screw adsorption device for mobile phone frames in this embodiment can automatically and efficiently perform the screw adsorption operation for mobile phone frames. That is, the automatic screw adsorption device for mobile phone frames in this embodiment has the advantages of novel structural design, high degree of automation and high working efficiency.

[0028] Example 2, as Figures 1 to 4 As shown, the difference between this embodiment 2 and embodiment 1 is that the movable flipping table 3 includes a front flipping ring 31 and a rear flipping ring 32, which are respectively in the shape of a ring. The front flipping ring 31 is rotatably mounted on the front support vertical plate 11, and the rear flipping ring 32 is rotatably mounted on the rear support vertical plate 12. The front flipping ring 31 and the rear flipping ring 32 are connected by an intermediate linkage rod 33.

The front end of the intermediate linkage rod 33 can be fastened to the front flip ring 31 by screwing, and the rear end of the intermediate linkage rod can also be fastened to the rear flip ring 32 by screwing. The front flip ring 31 and the rear flip ring 32 are rigidly connected through the intermediate linkage rod to ensure that the front flip ring 31 and the rear flip ring 32 rotate synchronously.

[0030] During the process of the rotating table drive mechanism 6 driving the movable rotating table 3 to rotate relative to the fixed base 1, the front rotating ring 31 rotates relative to the front support vertical plate 11 and the rear rotating ring 32 rotates relative to the rear support vertical plate 12, and the intermediate linkage rod 33 makes the front rotating ring 31 and the rear rotating ring 32 rotate synchronously.

[0031] Example 3, as Figures 1 to 4 As shown, the difference between this embodiment three and embodiment one is that: the tilting table drive mechanism 6 includes a tilting table drive motor 61 that is fastened to the front support vertical plate 11 or the rear support vertical plate 12, and a driven synchronous pulley 63 that is fastened to the front tilting ring 31 or the rear tilting ring 32.

[0032] During the process of the rotating table drive mechanism 6 driving the movable rotating table 3 to rotate, the controller controls the rotating table drive motor 61 to move. The rotating table drive motor 61 drives the movable rotating table 3 to rotate through the synchronous belt transmission mechanism composed of the active synchronous pulley 62, the driven synchronous pulley 63 and the transmission synchronous belt 64.

[0033] Example 4, as Figures 1 to 3 As shown, the difference between this embodiment four and embodiment two is that: the front support vertical plate 11 has a through hole that runs from front to back corresponding to the front flip ring 31, and the rear support vertical plate 12 has a through hole that runs from front to back corresponding to the rear flip ring 32. The front flip ring 31 and the rear flip ring 32 are respectively rotatably installed in the through holes of the front and rear vertical plates on the corresponding sides.

[0034] Among them, the front support vertical plate 11 has a number of bearing mounting holes 13 arranged in a ring array on the periphery of the front vertical plate through hole and the rear support vertical plate 12 has a number of bearing mounting holes 13 arranged in a ring array on the periphery of the rear vertical plate through hole. Each bearing mounting hole 13 of the front support vertical plate 11 is connected to the front vertical plate through hole and each bearing mounting hole 13 of the rear support vertical plate 12 is connected to the rear vertical plate through hole.

[0035] In addition, radial limiting bearings 71 are rotatably installed in each bearing mounting hole 13. Each radial limiting bearing 71 on the front support vertical plate 11 rolls in contact with the outer circumferential surface of the front flip ring 31, and each radial limiting bearing 71 on the rear support vertical plate 12 rolls in contact with the outer circumferential surface of the rear flip ring 32.

[0036] Furthermore, the front surface of the front support vertical plate 11 and the rear surface of the rear support vertical plate 12 are respectively equipped with a number of bearing seats 72 arranged in a ring array. Each bearing seat 72 is rotatably mounted with an axial limiting bearing 73. Each axial limiting bearing 73 on the front support vertical plate 11 is in rolling contact with the front surface of the front flip ring 31, and each axial limiting bearing 73 on the rear support vertical plate 12 is in rolling contact with the rear surface of the rear flip ring 32.

[0037] Example 5, as Figure 4 As shown, the difference between this embodiment 5 and embodiment 1 is that: the mobile phone frame adsorption mechanism 5 includes a suction cup cylinder mounting base 53 installed on the bracket part of the mobile phone frame conveyor belt 4, the suction cup cylinder mounting base 53 is equipped with a suction cup driving cylinder 51 for lifting action, and the driving end of the suction cup driving cylinder 51 is equipped with a mobile phone frame suction cup 52.

[0038] When the mobile phone frame conveyor belt 4 transports the mobile phone frame to the position of the mobile phone frame suction mechanism 5, the suction cup drive cylinder 51 drives the mobile phone frame suction cup 52 to move upward, so that the mobile phone frame suction cup 52 adsorbs and fixes the mobile phone frame.

[0039] Example 6, as Figure 3 As shown, the difference between this embodiment six and embodiment one is that the lifting drive mechanism 23 includes a lifting cylinder mounting seat 231 that is fastened to the fixed base 1 and located between the front support vertical plate 11 and the rear support vertical plate 12. The lifting cylinder mounting seat 231 is equipped with a vertically moving lifting drive cylinder 232, and the drive end of the lifting drive cylinder 232 is connected to the lifting movable frame 21.

[0040] During the synchronous lifting and lowering movement of the lifting frame 21 and the permanent magnet 22, in this fifth embodiment, the lifting frame 21 is driven to lift and lower by the lifting drive cylinder 232.

[0041] Example 7, as Figure 4 As shown, the difference between this embodiment seven and embodiment one is that: the bracket part of the mobile phone frame conveyor belt 4 is equipped with a blocking cylinder mounting seat 81, the blocking cylinder mounting seat 81 is equipped with a blocking drive cylinder 82 for lifting and lowering, and the driving end of the blocking drive cylinder 82 is equipped with a blocking block 83.

[0042] The support portion of the mobile phone frame conveyor belt 4 is equipped with an incoming material sensor 9 located in front of the blocking block 83. It should be noted that the incoming material sensor 9 in this embodiment seven can be a through-beam photoelectric sensor.

[0043] During the process of conveying the phone frame backward on the phone frame conveyor belt 4, when the material sensor 9 of the phone frame conveyor belt 4 receives the phone frame signal, the controller controls the blocking drive cylinder 82 to move. The blocking drive cylinder 82 pushes the blocking block 83 upward and moves the blocking block 83 onto the phone frame conveying path of the phone frame conveyor belt 4, so that the blocking block 83 blocks the phone frame, thereby making the phone frame accurately stop at the position of the phone frame adsorption mechanism 5, so as to ensure that the phone frame adsorption mechanism 5 can accurately adsorb and fix the phone frame.
