[0031] Specifically, please refer to Figure 1 , the lifting assembly line 2 is horizontally placed directly in front. The lifting assembly line 2 can adopt a device with lifting and transfer functions commonly used in existing production and manufacturing assembly lines, mainly to achieve operations such as lifting control of materials. The bin 1 is located behind the lifting assembly line 2 and relatively at the central position of the lifting assembly line 2.

[0032] In the embodiment, the material taking gripper module 3 comprises a translation mechanism 31, a lifting mechanism 32 and a material taking gripper mechanism 33. The translation mechanism 31 is connected with the lifting mechanism 32 to drive the lifting mechanism 32 to move forward and backward relative to the jacking assembly line 2. The lifting mechanism 32 is connected with the material taking gripper mechanism 33 to drive the material taking gripper mechanism 33 to move up and down relative to the jacking assembly line 2. Specifically, the translation mechanism 31 adopts an existing sliding drive mechanism composed of a motor, a sliding rail and a sliding block to realize translational driving control of the lifting mechanism 32. The lifting mechanism 32 adopts a lifting drive mechanism driven and controlled by a lifting cylinder or a lifting motor to realize lifting driving control of the material taking gripper mechanism 33. Finally, the material taking gripper mechanism 33 is adjusted in the forward and backward positions relative to the stock bin 1 to meet the requirements of taking materials.

[0033] In the embodiment, the material taking gripper mechanism 33 comprises a sliding table cylinder 331 and a material taking gripper assembly 332. The fixed end of the sliding table cylinder 331 is connected with the lifting mechanism 32. The sliding table cylinder 331 is driven by the lifting mechanism 32 to perform lifting movement. For example, if the lifting mechanism 32 adopts a lifting cylinder to realize lifting driving, the fixed end of the sliding table cylinder 331 is arranged at the output end of the lifting cylinder to realize lifting control of the sliding table cylinder 331. Further, the material taking gripper assembly 332 is arranged at the driving end of the sliding table cylinder 331. The material taking gripper assembly 332 is driven by the sliding table cylinder 331 to move left and right relative to the jacking assembly line 2. Specifically, the material taking gripper assembly 332 is composed of a clamping cylinder and two clamping jaws controlled and driven by the clamping cylinder to perform clamping movement. The fixed end of the clamping cylinder is arranged at the driving end of the sliding table cylinder 331. It should be noted that the clamping jaw assembly composed of a clamping cylinder and two clamping jaws to realize automatic clamping operation is relatively existing. In actual application, it can be designed and selected according to actual application requirements. In the embodiment, only a brief description is given, and no specific limitation is caused.

[0034] In the embodiment, the material taking transfer mobile module 5 comprises a YZ-axis transfer mechanism 51, a base 52, a synchronous belt assembly 53, a servo motor 54 and a transfer platform 55. The base 52 is connected with the YZ-axis transfer mechanism 51, and the base 52 is driven to move in the Y and Z directions by the YZ-axis transfer mechanism 51. Specifically, the YZ-axis transfer mechanism 51 comprises a Y-axis transfer mechanism 511 and a Z-axis transfer mechanism 512. The Z-axis transfer mechanism 512 is connected with the Y-axis transfer mechanism 511. The Y-axis transfer mechanism 511 drives the Z-axis transfer mechanism 512 to move back and forth. The base 52 is connected with the Z-axis transfer mechanism 512. The Z-axis transfer mechanism 512 drives the base 52 to move up and down, thereby adjusting the orientation of the base 52 relative to the hopper 1. The synchronous belt assembly 53 and the servo motor 54 are both arranged on the base 52. The synchronous belt assembly 53 is composed of a driving wheel, a driven wheel and a synchronous belt sleeved on the driving wheel and the driven wheel. One driving wheel in the synchronous belt assembly 53 is connected with the driving end of the servo motor 54. One side of the synchronous belt in the synchronous belt assembly 53 is connected with the transfer platform 55. The transfer platform 55 is driven to move back and forth in the X direction (i.e. left and right directions) by the servo motor 54 driving the synchronous belt assembly 53. It should be noted that the structures for realizing the movement in the YZ direction by the YZ-axis transfer mechanism 51 and the transmission driving by the servo motor 54 and the synchronous belt assembly 53 are both relatively common. In actual application, they can be designed and selected according to actual application requirements. In the embodiment, only a brief description is given, and no specific limitation is caused.

[0035] In the embodiment, the base 52 is further provided with an auxiliary slide rail 520 arranged horizontally along the X direction. The transfer platform 55 is slidably arranged on the auxiliary slide rail 520, which serves to guide the sliding of the transfer platform 55 and makes the transfer platform 55 slide more stably. The transfer platform 55 is provided with two groups of anti-deflection mechanisms which are distributed left and right. A first space for accommodating the mobile phone transportation platform is formed between the two groups of anti-deflection mechanisms. Each group of anti-deflection mechanisms comprises at least two limiting blocks 551 which are distributed in front of each other on the upper surface of the transfer platform 55. When the mobile phone transportation platform is placed in the first space, the at least two limiting blocks 551 on the left and right sides limit the mobile phone transportation platform, thereby enabling the transfer platform 55 to stably support the mobile phone transportation platform. In the embodiment, the limiting blocks 551 on the left and right sides are not identical in shape. In other embodiments, the limiting blocks 551 on the left and right sides can also be designed to be identical in shape, which should be subject to actual application.

[0036] Further, the front side of the base 52 is provided with a front side plate, the upper end of the front side plate is provided with a plurality of front blocking arms 522, the upper end of each of the plurality of front blocking arms 522 is bent outwardly forward; the rear side of the base 52 is provided with a rear side plate, the upper end of the rear side plate is provided with a plurality of rear blocking arms 523, the upper end of each of the plurality of rear blocking arms 523 is bent outwardly rearward. Through the arrangement of the front blocking arms 522 and the rear blocking arms 523, the mobile phone transportation platform can be prevented from shifting forward or rearward; when the switching platform 55 is in the initial position, the plurality of front blocking arms 522 and the rear blocking arms 523 are correspondingly located at the front and rear sides of the first space, so as to ensure that the mobile phone transportation platform placed in the first space is stable and cannot shift. Taking material taking as an example, when taking material, the switching platform 55 moves close to the bin 1, and then the first space is relatively close to the outside (i.e. not between the front blocking arms 522 and the rear blocking arms 523), and when the material is taken, the switching platform 55 gradually returns to the initial position, and then the first space also gradually returns to the position corresponding to the plurality of front blocking arms 522 and the rear blocking arms 523, so that the stability of the mobile phone transportation platform can be further ensured by the plurality of front blocking arms 522 and the rear blocking arms 523.

[0037] It should be noted that the structural design of the material storage gripper module 4 is the same as that of the aforementioned material taking gripper module 3, and the structural design of the material storage switching and moving module 6 is the same as that of the aforementioned material taking switching and moving module 5, the difference lies in the layout difference of the material storage and taking positions, so as to realize the operation of respectively storing and taking material, and then the material storage gripper module 4 can refer to the material taking gripper module 3, and the material storage switching and moving module 6 can refer to the material taking switching and moving module 5, which will not be described in detail in this embodiment.

[0038] In other embodiments, the material storage gripper module 4 and the material storage switching and moving module 6 can also be other any suitable mechanism or module capable of achieving material storage and taking and material storage switching and moving, which should be subject to actual application.

[0039] In this embodiment, the bin 1 is composed of a shelf 11 and a plurality of vertical plates 12, the plurality of vertical plates 12 are arranged on the shelf 11 and are distributed in front of and behind each other at equal intervals; each of the plurality of vertical plates 12 has a second space for accommodating the mobile phone transportation platform between the adjacent two vertical plates 12. Among them, the opposite side surfaces of the adjacent two vertical plates 12 are respectively provided with a plurality of blocking edges 120 which are distributed in front of and behind each other at equal intervals; each blocking edge 120 is provided with a supporting platform for placing the side edge of the mobile phone transportation platform thereon.

[0040] Specifically, the upper surface of each of the two corresponding front and rear edges 120 is provided with a notch, and the concave surfaces of the two notches are used to place the front and rear sides of the mobile phone transportation platform thereon. The distance between the inner side walls of the two notches is adapted to the width of the mobile phone transportation platform, and correspondingly, the distance between the outer walls of the two edges 120 is less than the width of the adapter platform 55, so that the adapter platform 55 can partially extend into or out of the two edges 120. Taking the storage as an example, when the adapter platform 55 slides horizontally towards the two edges 120, it also drives the mobile phone transportation platform to move outward, and the mobile phone transportation platform is no longer located between the front and rear stop arms 522 and 523 of the base 52. As the adapter platform 55 gradually extends into the two edges 120, the mobile phone transportation platform on the adapter platform 55 also extends into the two notches. After moving to the position, the adapter platform 55 is lowered and gradually extended, and the front and rear sides of the mobile phone transportation platform are placed on the concave surfaces of the two notches, that is, the storage is completed.

[0041] In actual implementation, the mobile phone transportation platform buffer system of the mobile phone assembly production line of the embodiment is arranged in a machine table 100. Specifically, the magazine 1, the jacking assembly line 2, the material taking gripper module 3, the storage gripper module 4, the material taking adapter moving module 5 and the storage adapter moving module 6 can be arranged at appropriate positions in the machine table 100 according to the above layout.

[0042] It should be understood that the above description can be improved or changed by those skilled in the art, and all such improvements and changes shall fall within the scope of the claims appended to the present application.
