[0027] As Figure 1 and Figure 2As shown, in one embodiment, an assembly apparatus 100 is provided, comprising: a first component carrier 101 movable in a first direction and through a cleaning assembly 102; a second component carrier 103 movable in the first direction and arranged collinearly with the first component carrier 101; a first handling assembly 104 between the first component carrier 101 and the second component carrier 103 and movable in a second direction; a second handling assembly 105 movable in a third direction; a third handling assembly 106 movable in the third direction, the first handling assembly 104 being between the second handling assembly 105 and the third handling assembly 106 in the third direction; a hold-down assembly 107 spaced from the second component carrier 103 in the third direction and spaced from the third handling assembly 106 in the first direction; a hold-down carrier 108 movable in the first direction between the third handling assembly 106 and the hold-down assembly 107; the first, second, and third directions being spatially intersecting two by two.

[0028] In the above embodiment, the first component can be a lens or the like, and the second component can be a screen or the like, and the first component and the second component need to be assembled together to form an assembly. The first component carrier 101 is used to carry the first component transferred from the previous process, and the first component carrier 101 is capable of moving along the first direction and passing through the cleaning assembly 102, so that the first component carried thereby can be cleaned to remove the dust possibly remaining from the previous process. The second component carrier 103 is used to carry the second component transferred from the previous process, and the second component carrier 103 is capable of moving along the first direction and arranged in line with the first component carrier 101, so that the first component carrier 101 and the second component carrier 103 can occupy the space in the first direction as much as possible and reduce the space occupation in other directions. In this context, "in line" means arranged along the same line, or said in another way, arranged along the same track. In this embodiment, two first component carriers 101 and two second component carriers 103 are designed, and each first component carrier 101 is arranged in line with a second component carrier 103. The number of the first component carriers 101 and the second component carriers 103 can be increased or decreased as needed. The first handling assembly 104 is located between the first component carrier 101 and the second component carrier 103, so that the first component carrier 101 and the second component carrier 103 can both reach the position of the first handling assembly 104 during movement. After the first component carried by the first component carrier 101 is cleaned by the cleaning assembly 102, it reaches the first handling assembly 104, the first handling assembly 104 moves along the second direction to pick up the first component, and then the first component carrier 101 retreats to the initial position. The second handling assembly 105 is used to carry the second component processed in the previous process to the second component carrier 103, and the second handling assembly 105 moves along the third direction, and the second component carrier 103 moves along the first direction, and the second handling assembly 105 places the second component on the second component carrier 103. The second component carrier 103 continues to move along the first direction to reach the first handling assembly 104, and the first handling assembly 104 moves along the second direction to place the first component on the second component, and the two components complete the preliminary assembly to form an assembly. The third handling assembly 106 is used to carry away the assembly after the preliminary assembly is completed. The third handling assembly 106 moves along the third direction, and in the third direction, the first handling assembly 104 is located between the second handling assembly 105 and the third handling assembly 106, so that the second handling assembly 105 and the third handling assembly 106 can both reach the first handling assembly 104 during movement along the third direction, and the third handling assembly 106 can thus carry away the assembly after the preliminary assembly is completed. The pressure maintaining assembly 107 is used to apply pressure to the assembled first component and second component for a period of time, so that the two components can be better adhered together.The pressure maintaining assembly 107 is arranged along the third direction away from the second component carrier 103, and the pressure maintaining assembly 107 is arranged along the first direction away from the third conveying assembly 106, so that the space on the side of the second component carrier 103 in the third direction is fully utilized, and the structure is compact. The pressure maintaining carrier 108 is used to carry and transfer the assembly. In the first direction, the pressure maintaining carrier 108 can move between the third conveying assembly 106 and the pressure maintaining assembly 107. When the pressure maintaining carrier 108 moves to the third conveying assembly 106, the third conveying assembly 106 places the preliminarily assembled assembly on the pressure maintaining carrier 108, and then the pressure maintaining carrier 108 moves to the pressure maintaining assembly 107, and the pressure maintaining assembly 107 applies pressure to the assembly for a period of time. The first direction, the second direction and the third direction are intersected with each other. As described above, the first component and the second component enter the component assembly device 100 from different directions. The route of the first component to the cleaning assembly 102 occupies the space in the first direction. The first conveying assembly 104 picks up the first component and preliminarily assembles to the second component, which occupies the space in the second direction. The route of the third conveying assembly 106 to pick up the assembly and transfer to the pressure maintaining assembly 107 occupies the space in the third direction. The pressure maintaining assembly 107 itself occupies the space on the side of the second component carrier 103 in the third direction. The route planning in the cleaning and pressure maintaining processes is fully considered. The cleaning and pressure maintaining processes can be completed in one component assembly device 100. The overall layout structure is compact and low in cost. The code scanner 118 is used to scan the second component.

[0029] As shown in FIG. 1, Figure 1 In an embodiment of the present application, the cleaning assembly 102 includes a cleaning member 1021 and a cleaning activation member 1022. The cleaning activation member 1022 is closer to the second component carrier 103 than the cleaning member 1021.

[0030] In the above embodiment, the first component carried by the first component carrier 101 undergoes two cleaning processes of cleaning and cleaning activation. The cleaning member 1021 can be in the form of ultrasonic cleaning, water cleaning, ultrasonic + water cleaning, and mainly plays a role of removing surface dust. The cleaning activation member 1022 can be in the form of plasma cleaning, flame spraying, etc., and plays a role of secondary cleaning and activation of the surface. The cleaning activation member 1022 is closer to the second component carrier 103 than the cleaning member 1021, which means that the first component is cleaned first and then cleaned and activated. In this way, when the first component is cleaned and activated, the surface of the first component is relatively clean after cleaning, which is more conducive to improving the activity and adhesion of the surface of the first component, and is conducive to the bonding between the cleaned first component and the second component.

[0031] As shown in FIG. 1, Figure 1As shown, in one embodiment of this application, the component assembly equipment 100 further includes a first vision sensor 109 and a controller (not shown in the figure). The first vision sensor 109 is used to capture working images of the cleaning and activating component 1022. The controller receives the working images and compares them with a standard image. When the comparison result exceeds a threshold, the controller issues an alarm signal.

[0032] In the above embodiments, taking plasma cleaning and activation as an example, the cleaning and activation component 1022 sprays a plasma beam during operation. The image of this plasma beam is captured by the first visual sensor 109 and transmitted to the controller. The controller stores standard images. When the length, width, or brightness of the working image received by the controller is less than the length, width, or brightness of the plasma beam in the standard image and reaches a certain threshold, it indicates that the cleaning and activation component 1022 has insufficient cleaning ability. At this time, the controller issues an alarm signal to remind the staff to replace or adjust it. Similarly, when flame spraying is used for cleaning and activation, the working image is the length, width, or brightness of the flame. When the length, width, or brightness of the working image received by the controller is less than the length, width, or brightness of the flame in the standard image and reaches a certain threshold, it indicates that the cleaning and activation component 1022 has insufficient cleaning ability. At this time, the controller issues an alarm signal to remind the staff to replace or adjust it.

[0033] like Figure 1 and Figure 3 As shown, in one embodiment of this application, the component assembly equipment 100 further includes a second vision sensor 110. The second vision sensor 110 is used to identify the cleanliness of the assemblies carried on the second component carrier 103; the third conveying assembly 106 includes a waste material conveying component 1061 and a qualified material conveying component 1062. The waste material conveying component 1061 is used to convey assemblies whose cleanliness is not up to standard as identified by the second vision sensor 110 to the waste buffer station 111, and the qualified material conveying component 1062 is used to convey assemblies whose cleanliness is up to standard as identified by the second vision sensor 110 to the pressure holding carrier 108.

[0034] In the above embodiment, after the first component and the second component carried on the second component carrier 103 are preliminarily assembled together to form an assembly, the second visual sensor 110 takes a photo of the assembly to identify whether the cleanliness of the assembly meets the standard. For example, after the second visual sensor 110 takes a photo of the assembly, the number of spots in the photo can be identified. If the number of spots exceeds a preset value, the cleanliness does not meet the standard, otherwise, the cleanliness meets the standard. Alternatively, after the second visual sensor 110 takes a photo of the assembly, the diameter of the spots in the photo can be identified. If the diameter of the spots exceeds a preset value, the cleanliness does not meet the standard, otherwise, the cleanliness meets the standard. The identification of the number and the diameter of the spots in the photo can be achieved by a machine learning algorithm, which will not be described in detail herein. If the cleanliness does not meet the standard, the third conveying assembly 106 moves in the third direction, and the waste conveying member 1061 picks up the assembly and places it in the waste buffer station 111. If the cleanliness meets the standard, the qualified material conveying member 1062 picks up the assembly and places it in the pressure maintaining carrier 108, and the pressure maintaining carrier 108 carries the assembly to the pressure maintaining assembly 107 for pressure maintaining. In this way, the third conveying assembly 106 is used to realize the separate conveying and processing of the assemblies with qualified cleanliness and unqualified cleanliness, and the occupied space is small.

[0035] In an embodiment of the present application, the second visual sensor 110 is capable of moving in the third direction. In this way, one second visual sensor 110 can be used to scan the assemblies on different second component carriers 103.

[0036] As shown in FIG. 1, Figure 1 In an embodiment of the present application, the component assembly device 100 further comprises a fourth conveying assembly 112, which is capable of moving in the third direction. In the first direction, the third conveying assembly 106 and the fourth conveying assembly 112 are respectively located on the two sides of the pressure maintaining assembly 107. In the first direction, the pressure maintaining carrier 108 is capable of moving between the third conveying assembly 106 and the fourth conveying assembly 112.

[0037] In the above embodiment, the fourth conveying assembly 112 moves in the third direction to carry the assembly after pressure maintaining out of the component assembly device 100 and into the next process. When working, the pressure maintaining carrier 108 first moves in the first direction to the third conveying assembly 106, the third conveying assembly 106 places the assembly with qualified cleanliness on the pressure maintaining carrier 108, then the pressure maintaining carrier 108 moves in the first direction to the pressure maintaining assembly 107, the pressure maintaining assembly 107 applies pressure to the assembly for a certain period of time, and then the pressure maintaining carrier 108 continues to move in the first direction to the fourth conveying assembly 112, and the fourth conveying assembly 112 carries the assembly out of the component assembly device 100. The entire device fully utilizes the space in each direction, and the layout is compact.

[0038] In one embodiment of this application, the first transport assembly 104, the second transport assembly 105, the third transport assembly 106, and the fourth transport assembly 112 are spaced apart from the first component support 101 in the second direction. Correspondingly, the first transport assembly 104, the second transport assembly 105, the third transport assembly 106, and the fourth transport assembly 112 are also spaced apart from the second component support 103 and the pressure-holding support 108 in the second direction. That is, in one embodiment of this application, all transport assemblies are suspended above the first component support 101, the second component support 103, and the pressure-holding support 108, making full use of the space in the height direction.

[0039] like Figure 1 As shown, in one embodiment of this application, the component assembly equipment 100 further includes a feeding bin 117, a robotic arm 113, and a tray pull-out assembly 114. The tray pull-out assembly 114 is used to pull out the tray from the feeding bin 117, and the robotic arm 113 is used to place the first component in the tray onto the first component support 101.

[0040] In the above embodiment, the first component is placed in a tray, which is then placed in a loading bin 117. After the loading bin 117 reaches a predetermined position, the tray pull-out assembly 114 pulls the tray out of the loading bin 117. The robotic arm 113 can be, for example, a four-axis robotic arm, to pick up the first component, thereby achieving automated transfer.

[0041] like Figure 4 As shown, in one embodiment of this application, the robotic arm 114 is equipped with a pressure sensor 115 and a detachable probe 116.

[0042] Pressure sensor 115 is used to detect the pressure applied by robot arm 114 to the first component. After a period of operation, probe 116 is installed on the robot arm to recalibrate the working height of robot arm 114. Specifically, after installing probe 116, robot arm 114 is lowered until pressure sensor 115 reaches a preset value. At this point, the height of robot arm 114 is set to the calibrated original height, for example, marked as 0. After multiple movements of robot arm 114, installing probe 116 to find the original height again ensures accurate subsequent working height.

[0043] In one embodiment of this application, the component assembly equipment 100 further includes a housing with a receiving space, within which the first component carrier 101, the cleaning assembly 102, the second component carrier 103, the first transport assembly 104, the second transport assembly 105, the third transport assembly 106, the pressure holding assembly 107, and the pressure holding carrier 108 are located. Thus, the entire cleaning, pressure holding, and transfer process is conducted within a relatively enclosed space, which is beneficial for achieving a dust-free environment.

[0044] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application.
