[0036] Referring to Figures 1 to 3 The alignment assembly machine provided by the embodiment of the present application mainly comprises a rack 1, a first conveying mechanism 2, a second conveying mechanism 3, a mechanical hand, a first detection mechanism 4 and a second detection mechanism 5. The rack 1 is provided with a first station and a second station. The first conveying mechanism 2 is arranged on the rack 1 and used for conveying a first workpiece to the first station. The second conveying mechanism 3 is arranged on the rack 1 and used for conveying a second workpiece to the second station. The mechanical hand is arranged on the rack 1 and used for obtaining the second workpiece from the second station, transferring the second workpiece from the second station to the first station, and attaching the second workpiece on the first workpiece. The first detection mechanism 4 is used for detecting the position of the first workpiece on the first station. The second detection mechanism 5 is arranged between the first station and the second station and used for detecting the position of the second workpiece in the process of transferring the second workpiece from the second station to the first station.

[0037] In the alignment assembly machine table, the first workpiece is driven by the first conveying mechanism 2 to the first station, the second workpiece is driven by the second conveying mechanism 3 to the second station, and the subsequent assembly work is prepared, the first detection mechanism 4 detects the position of the first workpiece and feeds back, the manipulator executes the action of obtaining and transferring the second workpiece, since the second detection mechanism 5 is arranged between the first station and the second station, in the process that the manipulator transfers the second workpiece from the second station to the first station, the second detection mechanism 5 can detect the position of the second workpiece obtained by the manipulator and feed back, the manipulator can adjust the operation action and the motion track according to the position information of the first workpiece detected by the first detection mechanism 4 and the position information of the second workpiece detected by the second detection mechanism 5, transfer the second workpiece to the first station and adhere together with the first workpiece, thereby completing the assembly between the two.

[0038] The first conveying mechanism 2, the second conveying mechanism 3 and the manipulator are arranged, the steps of manual feeding and manual adhering are saved, the feeding and adhering speed is accelerated, and therefore the assembly efficiency is improved.

[0039] It is conceivable that the first station and the second station are two specific positions on the rack 1, the first workpiece is conveyed to the first station, the first workpiece can be left in the rack 1, or the first workpiece can be left in the first conveying mechanism 2 or other structures, and the left position has a corresponding relationship with the first station in the direction, and correspondingly, the second workpiece is conveyed to the second station according to the specific situation of the first workpiece being conveyed to the first station, which will not be described here. In this embodiment, when each workpiece is conveyed to the position, the corresponding conveying mechanism stops moving, and each workpiece is left on the corresponding conveying mechanism.

[0040] Please refer to Figure 2 , wherein, Figure 2The first workpiece carrier plate 6 in the first workpiece carrier plate 6 is conveyed to the first station, and the second workpiece carrier plate 7 is conveyed to the second station. In a specific embodiment, the alignment assembly machine also includes a first workpiece carrier plate 6 for carrying a plurality of first workpieces and a second workpiece carrier plate 7 for carrying a plurality of second workpieces. The first conveying mechanism 2 is used to carry the first workpiece carrier plate 6 and convey the first workpiece carrier plate 6 to the first station. The second conveying mechanism 3 is used to carry the second workpiece carrier plate 7 and convey the second workpiece carrier plate 7 to the second station. On the one hand, the first workpiece carrier plate 6 and the second workpiece carrier plate 7 respectively provide stable carrying and positioning basis for the first workpiece and the second workpiece. Compared with directly conveying the corresponding workpiece by the conveying mechanism, the corresponding workpiece can be better fixed by the workpiece carrier plate, the shaking and displacement of the workpiece during conveying and transferring can be reduced, and the workpiece carrier plate can convey a plurality of workpieces at a time, thereby improving the transportation efficiency. On the other hand, since the first workpiece carrier plate 6 and the second workpiece carrier plate 7 respectively carry a plurality of first workpieces and second workpieces, after the first workpiece carrier plate 6 and the second workpiece carrier plate 7 are conveyed to the position, the assembly between a plurality of groups of first workpieces and second workpieces can be completed through the multiple detections of the first detection mechanism 4 and the second detection mechanism 5 and the multiple transfer actions of the mechanical hand, thereby further improving the assembly efficiency.

[0041] Please refer to Figures 1 to 3 The rack 1 is provided with a conveying passage 11, and the rack 1 is provided with a first feeding port 12 and a conveying port 13 which respectively communicate with the conveying passage 11. The second conveying mechanism 3 includes a first displacement mechanism 31 and a second displacement mechanism 32. The first displacement mechanism 31 is movably arranged in the conveying passage 11 and is used to convey the second workpiece carrier plate 7 from the first feeding port 12 to the conveying port 13. The second displacement mechanism 32 is movably arranged on the rack 1 and is used to convey the second workpiece carrier plate 7 from the conveying port 13 to the second station. By arranging the conveying passage 11 in the rack 1, conveying the second workpiece by the first displacement mechanism 31 in the conveying passage 11, and conveying the second workpiece by the second displacement mechanism 32 on the rack 1, the conveying path of the second conveying mechanism 3 can be optimized. The first displacement mechanism 31 and the second displacement mechanism 32 can simultaneously convey different second workpiece carrier plates 7, thereby improving the conveying efficiency and effectively arranging the space of the rack 1, which is conducive to the compactness of the overall structure.

[0042] Please refer to Figure 2 and Figure 3In a further embodiment, the second conveying mechanism 3 further comprises a transfer mechanism 33 for picking up the second workpiece carrier 7 from the first displacement mechanism 31 and transferring the second workpiece carrier 7 from the first displacement mechanism 31 to the second displacement mechanism 32. The presence of the transfer mechanism 33 enables the second workpiece carrier 7 to be smoothly transferred from the first displacement mechanism 31 to the second displacement mechanism 32, avoiding possible interruptions or delays, and the transfer mechanism 33 is exclusively responsible for the transfer operation of the second workpiece carrier 7, which helps to improve the positional accuracy of the second workpiece carrier 7 during the transfer from the first displacement mechanism 31 to the second displacement mechanism 32.

[0043] In the present embodiment, the transfer mechanism 33 is a suction mechanism, which is provided with at least two suction heads, each of which is arranged to act on the surface of the second workpiece carrier 7 on opposite sides.

[0044] Referring to Figure 5 , the second workpiece is located in the first direction D1 of the conveying port 13. The second displacement mechanism 32 comprises a base plate 321 and two positioning blocks 322 arranged on the base plate 321, the base plate 321 is movably arranged on the rack 1 in the first direction D1, the two positioning blocks 322 are spaced apart in the second direction D2, and the positioning blocks 322 are movable in the second direction D2, the first direction D1 is not parallel to the second direction D2. When the robot picks up the second workpiece from the second workpiece, the second workpiece carrier 7 is clamped between the two positioning blocks 322. Since the base plate 321 can move in the first direction D1, the second workpiece is conveyed to the second workpiece in the first direction D1, and the positioning blocks 322 can move in the second direction D2, the cooperation between the base plate 321 and the positioning blocks 322 can accurately position the second workpiece carrier 7. Further, when the robot picks up the second workpiece, the second workpiece carrier 7 is clamped between the positioning blocks 322, so as to ensure that the second workpiece can be stably peeled off from the second workpiece carrier 7, and the two positioning blocks 322 can be moved in the second direction D2 to clamp the second workpiece carrier 7 of different sizes, thereby enhancing the applicability of the structure.

[0045] In the present embodiment, the robot peels off the second workpiece from the second workpiece carrier 7 by suction.

[0046] Referring to Figures 1 to 3The conveying channel 11 comprises horizontal channels and vertical channels which are connected, the horizontal channels are communicated with the first feeding port 12, and the vertical channels are communicated with the conveying port 13. The horizontal channels are provided with first guide rails 111 extending along the second direction D2, and the vertical channels are provided with second guide rails 112 extending along the vertical direction H. The first displacement mechanism 31 comprises a support seat 311 for supporting the second workpiece carrier plate 7, and the support seat 311 is slidably connected with the first guide rails 111 and the second guide rails 112 respectively. The second feeding port 14 is further arranged on the rack 1, and the first conveying mechanism 2 is arranged on the rack 1 and located directly above the horizontal channels. The first conveying mechanism 2 is used for driving the first workpiece to move in the first direction D1 and conveying the first workpiece carrier plate 6 from the second feeding port 14 to the first work station. The first work station, the first detection mechanism 4 and the second work station are arranged side by side in the second direction D2.

[0047] Since the first conveying mechanism 2 is located directly above the horizontal channels and drives the first workpiece to move in the first direction D1 to the first work station, the second workpiece carrier plate 7 is conveyed from the conveying port 13 to the second work station in the first direction D1 by the second displacement mechanism 32, and the conveying port 13 is communicated with the vertical channels. Therefore, the conveying processes of the first conveying mechanism 2 and the second conveying mechanism 3 are independent of each other, and on the basis of the interval for accommodating the first detection mechanism 4 between the first work station and the second work station, the first feeding port 12 and the second feeding port 14 can be arranged on the same side or adjacent side and close to each other, which facilitates the feeding of the first workpiece and the second workpiece and improves the feeding efficiency.

[0048] Please refer to Figure 4 In the above embodiment in which the first conveying mechanism 2 is used for carrying the first workpiece carrier plate 6 and conveying the first workpiece carrier plate 6 to the first work station, the first conveying mechanism 2 comprises a synchronous belt 21 and at least two synchronous pulleys 22. The synchronous belt 21 is sleeved on each synchronous pulley 22 and is used for carrying the first workpiece carrier plate 6. The synchronous pulleys 22 are rotatably arranged on the rack 1, and when one of the synchronous pulleys 22 rotates, the synchronous belt 21 drives the first workpiece carrier plate 6 to move in the first direction D1. The synchronous belt 21 transmission is a kind of high-efficiency transmission mode, which has the advantages of simple structure. In the process of transmitting power from the synchronous pulley 22 to the synchronous belt 21 and then to the first workpiece carrier plate 6, the energy loss is small, and the production efficiency of the whole alignment assembly machine is improved. In the embodiment, the first conveying mechanism 2 is provided with two groups of synchronous belts 21 and synchronous pulleys 22 in the second direction D2, so that the first workpiece carrier plate 6 and the first workpiece thereon can be uniformly and stably supported and transported.

[0049] In a further embodiment, the first conveying mechanism 2 also includes two movable seats 23 arranged opposite to each other in the second direction D2, and the frame 1 is provided with a third guide rail 15 extending in the second direction D2. The movable seat 23 is slidingly connected to the third guide rail 15, and the synchronous pulley 22 is rotatably provided on the movable seat 23. The adjustable setting of the movable seat 23 and the synchronous pulley 22 enables the first conveying mechanism 2 to adapt to first workpiece carriers 6 of different sizes, or to adjust the position of the first workpiece carrier 6 by adjusting the position of the movable seat 23 to meet specific detection requirements.

[0050] See also Figure 2 and Figure 3 In a specific embodiment, a first detection mechanism 4 is movably mounted on the frame 1 and is used to detect the position of the first workpiece from above the first workstation. A second detection mechanism 5 is fixed to the frame 1 and is used to detect the second workpiece from below the manipulator. Due to the movable nature of the first detection mechanism 4, it can flexibly adjust the detection angle and range to accommodate first workpieces of varying sizes, shapes, or placements. The second detection mechanism 5 is fixed to the frame 1, facilitating stable detection of the second workpiece as it is transferred from the second workstation to the first. The first detection mechanism 4 and the second detection mechanism 5 perform detection from above and below, respectively, which facilitates the spatial arrangement of the overall structure.

[0051] See also Figure 3 In one embodiment of the above-mentioned first detection mechanism 4 for detecting the position of the first workpiece at the first workstation, a sliding assembly 8 is provided between the first detection mechanism 4 and the frame 1. The sliding assembly 8 includes a connecting seat 81, a first slide rail 82, and a second slide rail 83. The first slide rail 82 extends along a first direction D1, and the second slide rail 83 extends along a second direction D2. The first detection mechanism 4 is movably connected to the connecting seat 81 along a vertical direction H. The connecting seat 81 is slidably connected to the first slide rail 82, and the first slide rail 82 is slidably connected to the second slide rail 83. The first direction D1, the second direction D2, and the vertical direction H are mutually perpendicular. Because the first detection mechanism 4 can move in three mutually perpendicular directions, it can perform comprehensive inspection of the first workpiece, thereby improving the accuracy of the inspection.

[0052] In this embodiment, the first detection mechanism 4 and the second detection mechanism 5 are both CCD detection cameras.

[0053] In the above embodiments, a cover is provided on the frame 1, which encloses and forms a relatively closed space, and the above-mentioned conveying, testing and assembly work are all carried out in the space.
