Description

Technical Field

[0001] This utility model relates to the field of automatic assembly technology of mobile terminal device motherboards, and specifically to an automatic assembly device for mobile terminal device motherboards. Background Technology

[0002] Currently, the assembly process of mobile terminal device motherboards mainly relies on manual labor in conjunction with specialized auxiliary fixtures. Specifically, operators first manually lift the motherboard to the barcode scanner for scanning and binding. After scanning, the motherboard is then assembled into the phone casing within the fixture, and a screwdriver is used to sequentially pick up and tighten the screws to secure the motherboard. The entire process requires multiple manual operations, is tedious, and highly repetitive.

[0003] Because the assembly process heavily relies on operator skill, it can easily lead to unstable production quality and assembly efficiency, resulting in issues such as inconsistent assembly precision and poor fastening. Furthermore, prolonged manual operation not only involves high labor intensity but also limits the improvement of production cycle time.

[0004] With the continuous improvement of automation levels in the 3C electronics manufacturing industry, the demand for automated assembly equipment on production lines is becoming increasingly urgent. Currently, the assembly of mobile terminal motherboards is still mainly done manually. Therefore, there is a pressing need for automated assembly equipment for mobile terminal motherboards that can replace manual labor, improve assembly efficiency and consistency, and reduce labor intensity.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model achieves a fully automated operation process for mobile terminal device motherboards from material picking, transfer, assembly and fastening by setting up a collaborative structure of material hopper, material picking robot, transfer station, assembly robot, screw fastening module and production line. It can effectively replace traditional manual operation, significantly improve assembly efficiency and assembly consistency, reduce labor intensity and reduce the impact of human factors on product quality.

[0018] By incorporating lifting devices and carriers at the assembly station, stable support is achieved between the motherboard and the phone casing during screw tightening, ensuring that the motherboard and phone casing are not affected by assembly line vibrations during screw tightening.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting the present utility model. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting the present utility model.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0036] like Figures 1 to 4 As shown, an automated assembly equipment for mobile terminal device motherboards includes a hopper 1, a material handling robot 2, a transfer station 3, an assembly robot 4, a screw-fastening module 5, and a production line 6. The hopper 1 is used to store multiple motherboards. The material handling robot 2 is used to transfer the motherboards in the hopper 1 to the transfer station 3. The assembly robot 4 is used to transfer the motherboards placed on the transfer station 3 to the assembly station of the production line 6. The screw-fastening module 5 is used to fasten screws onto the motherboards and mobile phone casings at the assembly station.

[0037] The assembly station includes a lifting device 7 and a carrier 8 disposed above the lifting device 7.

[0038] The lifting device 7 includes a lifting cylinder 9, the extended end of which is connected to the carrier connecting plate 10. The carrier 8 is positioned above the carrier connecting plate 10. When the screw-locking module 5 screws onto the motherboard and the phone casing, the lifting cylinder 9 drives the carrier connecting plate 10 and the carrier 8 above it to rise together, causing them to detach from the production line 6. This ensures that the motherboard and the phone casing are not affected by the vibration of the production line during the screw-locking process.

[0039] like Figure 10 and Figure 11 As shown, the production line 6 includes a frame 11, on which a transmission device 12 and a lifting device 7 are mounted; multiple carriers 8 are provided and are sequentially transported to the carrier connecting plate 10 of the lifting device 7 via the transmission device 12; mobile phone casings are pre-placed on the carriers 8; multiple Z-axis limiting blocks 13 are provided on the side of the lifting device 7 on the frame 11 to limit the Z-axis position of the carriers 8 during the lifting process; a limiting cylinder 14 is provided on the front side of the carrier connecting plate 10 to limit the carriers 8 after they are transported to the carrier connecting plate 10 via the transmission device 12, preventing the carriers 8 from being pushed forward by the transmission device 12.

[0040] A first camera module 15 is installed above the material hopper 1. The first camera module 15 is used to scan and photograph the motherboards inside the material hopper 1. The first camera module 15 scans and confirms the motherboards to record the coding information of each motherboard leaving the hopper, thereby realizing traceable management of motherboard leaving the hopper data, which is beneficial for quality tracking and production information statistics in the subsequent assembly process.

[0041] like Figure 5 As shown, a second camera module 16 is provided on the transfer path of the assembly robot 4 from the transfer station 3 to the assembly line 6. The second camera module 16 is used to take pictures of the bottom of the motherboard gripped by the assembly robot 4. It can promptly determine whether there are foreign objects, dust or other impurities on the bottom of the motherboard, thereby avoiding the impact of foreign object residue on the assembly accuracy and reliability of the motherboard and the mobile phone shell, and improving the stability of the assembly quality.

[0042] A third camera module 17 is provided above the assembly station of the production line 6. The third camera module 17 is used to take pictures of the motherboard transferred to the assembly station by the assembly robot 4 and the mobile phone casing located at the assembly station, so as to ensure that the position between the motherboard and the mobile phone casing is accurate.

[0043] like Figures 6-9As shown, the transfer station 3 includes a motherboard placement position 18, and a clamping device is provided on the side of the motherboard placement position 18. The clamping device is used to clamp and position the motherboard on the motherboard placement position 18.

[0044] The clamping device includes an X-direction limiting block 19 and a Y-direction limiting block 20 disposed on the outer side of the motherboard placement position 18 in the X and Y directions, respectively, and an XY clamping mechanism and an unlocking mechanism 22 disposed on the inner side of the motherboard placement position 18. The XY clamping mechanism cooperates with the X-direction limiting block 19 and the Y-direction limiting block 20 to achieve clamping and positioning of the motherboard in the X and Y directions.

[0045] The bottom of the unlocking mechanism 22 is connected to the lifting cylinder 23. The unlocking mechanism 22 includes two locking blocks 24, each with an inclined contact surface 25. The XY clamping mechanism includes a movable X-axis slider 26 and a Y-axis slider 27. A spring 28 is connected to the first end of both the X-axis slider 26 and the Y-axis slider 27, and their second ends cooperate with the X-axis limiting block 19 and the Y-axis limiting block 20, respectively, to achieve positioning and clamping of the motherboard. Both the X-axis slider 26 and the Y-axis slider 27 have guide slopes 29 that match the inclined contact surfaces 25.

[0046] Specifically, when the lifting cylinder 23 extends, it drives the unlocking mechanism 22 to rise, causing the inclined contact surface 25 of the locking block 24 to contact the guide slope 29, compressing the spring 28, and driving the X-axis slider 26 and Y-axis slider 27 to move away from the motherboard placement position 18, thereby unlocking the motherboard; when the lifting cylinder 23 retracts, the inclined contact surface 25 of the locking block 24 separates from the guide slope 29, the spring 28 resets, and drives the X-axis slider 26 and Y-axis slider 27 to move closer to the motherboard placement position 18, thereby clamping and positioning the motherboard.

[0047] The hopper 1 and the transfer station 3 are respectively located below the initial and final positions of the moving path of the material handling robot 2.

[0048] like Figure 12 As shown, the assembly robot 4 includes a force sensor 30, which is connected to a vacuum suction head 32 via a connector 31. The vacuum suction head 32 is used to connect to the motherboard.

[0049] The transfer station 3 and the assembly station are respectively located below the initial and final positions of the robotic arm's movement path.
