Description

Technical Field

[0001] This utility model relates to the field of lens module processing equipment, and in particular to an assembly structure for a line-connected assembly machine. Background Technology

[0002] The current lens module manufacturing process mainly includes the initial material loading and tray placement, the assembly of various components, and the final glue application and unloading. It is evident that the entire process involves multiple pieces of equipment, which work together to form the complete lens module assembly process. The most crucial step is the assembly of the individual components, which involves assembling the various parts of a lens via assembly axes before moving them to subsequent workstations.

[0003] Existing assembly equipment consists of individual units, meaning these units cannot be connected to form a production line capable of processing multi-specification lens modules. They can only assemble a single specification (e.g., single-layer or double-layer, with or without partitions) at a time. Furthermore, due to the current trend towards integrated equipment, these individual assembly machines are no longer sufficient to meet the requirements of integrated production lines.

[0004] In view of this, this technical solution proposes an inline assembly machine structure, in which each assembly machine can be connected and can process various lens specifications. The integrated line structure not only occupies little space but also facilitates centralized management. Materials do not need to be manually transferred, which greatly improves processing efficiency. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in the related technologies. Therefore, the main objective of this invention is to provide an inline assembly machine structure, which addresses the problems of existing single-assembly equipment for lens module assembly lacking the ability to process multiple specifications and lacking an inline structure.

[0006] To achieve the above objectives, this utility model provides a line-connected assembly machine structure, including an assembly line composed of connecting lines for various assembly machine components.

[0007] Each of the assembly machine components includes a first assembly mechanism and a second assembly mechanism respectively disposed on one side of the table.

[0008] The first assembly mechanism includes a lens positioning camera located near the lens hopper. A lens assembly Z-axis is located on one side of the lens positioning camera, and a lens assembly X-axis is located behind the lens assembly Z-axis. A lens barrel receiving mechanism for receiving incoming materials is located on the side near the tray-mounting device. A lens barrel positioning camera is located near the lens barrel receiving mechanism. An assembly tray X-axis and an assembly tray Y-axis are located between the lens barrel receiving mechanism and the lens assembly X-axis.

[0009] The second assembly mechanism includes a spacer assembly X-axis disposed on the other side of the lens assembly X-axis. An assembly positioning camera is disposed near the spacer assembly X-axis. An assembly feeding shaft is disposed on the other side of the assembly positioning camera, opposite to the lens barrel receiving mechanism. The assembly feeding shaft is lifted and lowered by an assembly unloading lifting shaft on one side. A spacer assembly Z-axis, a spacer positioning camera, and a spacer vibrating disk are disposed behind the assembly unloading lifting shaft. The assembly disk X-axis and the assembly disk Y-axis are also disposed between the spacer assembly X-axis and the assembly positioning camera.

[0010] As a further embodiment of this invention, the first assembly mechanism also includes a lens collar support plate disposed near the lens hopper.

[0011] As a further improvement of this utility model, the number of assembly machine components in the assembly line is at least 4.

[0012] As a further embodiment of this utility model, the assembly line also includes a frame disposed outside each of the assembly machine components.

[0013] As a further embodiment of this invention, the Z-axis and X-axis of the lens assembly are both multi-axis structures driven by linear servo motors.

[0014] As a further improvement of this invention, the lens assembly Z-axis and lens assembly X-axis are both handled by a negative pressure suction head.

[0015] As a further embodiment of this utility model, the assembly unloading lifting shaft is a lifting structure consisting of gears and lead screws.

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

[0017] This solution connects multiple assembly machine components into a continuous assembly line, and integrates a first assembly mechanism and a second assembly mechanism in each component, thereby realizing the continuous and automated assembly and transfer of lenses, lens barrels and spacers.

[0018] The production line can easily adapt to the assembly needs of lens modules with different layers (such as single-layer, double-layer, or multi-layer) and whether or not they include spacers by increasing or decreasing the number of assembly machine components. This overcomes the drawbacks of traditional single-unit equipment with limited functionality and frequent changeovers. The entire assembly process utilizes precise positioning by vision systems such as lens positioning cameras, lens barrel positioning cameras, assembly positioning cameras, and spacer positioning cameras. Combined with the automated operation of a series of high-precision motion axes, including the Z-axis for lens assembly, X-axis for lens assembly, X-axis for assembly tray, Y-axis for assembly tray, and Z-axis for spacer assembly, the assembly process ensures high precision and consistency. This improves production efficiency and product quality, reduces manual intervention and material turnover, and the integrated line structure saves space and facilitates centralized management, forming a highly efficient and adaptable automated lens module assembly production line.

[0028] Please see the appendix Figure 1-5 ,

[0029] The assembly structure of the line-type assembly machine in this technical solution is mainly composed of multiple assembly machine components (20) connected in sequence to form an assembly line (2). Each assembly machine component (20) has a first assembly mechanism (200) and a second assembly mechanism (201) respectively on both sides of the table.

[0030] More specifically, in the first assembly mechanism (200), a lens positioning camera (2007) is set near the lens hopper (2009) to identify the position of the lens. A lens assembly Z-axis (2005) is provided on one side for vertically picking up and placing lenses. A lens assembly X-axis (2001) is arranged behind the lens assembly Z-axis (2005) for horizontally moving the lens. A lens barrel receiving mechanism (2004) is provided on the side near the tray device (1) for receiving lens barrels transported from upstream. A lens barrel positioning camera (2006) is provided near the lens barrel receiving mechanism (2004) to perform visual positioning of the lens barrel. An assembly tray X-axis (2002) and an assembly tray Y-axis (2003) are also arranged between the lens barrel receiving mechanism (2004) and the lens assembly X-axis (2001) for precise positioning and transfer during the assembly process.

[0031] The second assembly mechanism (201) is located on the other side of the lens assembly X-axis (2001), including the spacer assembly X-axis (2010). Near it is an assembly positioning camera (2011) for detecting the assembly status. On the other side of the assembly positioning camera (2011) is an assembly feeding shaft (2012), which is arranged opposite to the lens barrel receiving mechanism (2004). The assembly feeding shaft (2012) realizes the lifting and unloading action through the assembly unloading lifting shaft (2013) on one side. Behind the assembly unloading lifting shaft (2013), there are also spacer assembly Z-axis (2014), spacer positioning camera (2015) and spacer vibrating plate (2016) arranged in sequence for spacer identification, picking and placing and feeding. Assembly plate X-axis (2002) and assembly plate Y-axis (2003) are also arranged between the spacer assembly X-axis (2010) and the assembly positioning camera (2011) to realize positioning and transfer during the assembly process.

[0032] This solution can support the continuous automated assembly of lens modules of various specifications. The assembly line (2) adopts a modular design, and the number of assembly machine components (20) can be flexibly increased or decreased according to actual production needs, so as to adapt to the production of camera modules of various specifications such as different number of lens layers (such as single layer, double layer or multi-layer) and whether or not to assemble spacers, thus avoiding the problems of traditional single-machine equipment having single function and frequent line changeover. The entire assembly process, from lens barrel receiving, lens picking and positioning, spacer supply and assembly to finished product transfer, is fully automated. Multiple vision positioning mechanisms, including a lens positioning camera (2007), lens barrel positioning camera (2006), spacer positioning camera (2015), and assembly positioning camera (2011), combined with various precision moving axes (such as the lens assembly Z-axis (2005), lens assembly X-axis (2001), assembly tray X-axis (2002), assembly tray Y-axis (2003), and spacer assembly Z-axis (2014),) achieve high-precision and high-consistency assembly, significantly reducing errors and inconsistencies caused by manual intervention. The interconnected structure can also seamlessly connect with the front-end tray-mounting equipment (1) and the rear-end dispensing equipment (3) to form a complete automated production line. This not only significantly improves production efficiency and capacity but also reduces the overall equipment footprint, facilitating centralized management and maintenance. Thus, while ensuring product quality, it achieves efficient, flexible, and centralized lens module production.

[0033] Reference Appendix Figure 4 In a preferred embodiment of this invention, the first assembly mechanism (200) may be further equipped with a lens collar support plate (2008). This support plate is located near the lens hopper (2009). For example, when the lens hopper (2009) dispenses a lens with a collar, the lens collar support plate (2008) can support and stabilize the lens collar from below, cooperating with the Z-axis (2005) and X-axis of the lens assembly to ensure the stability of the lens collar during the assembly process with the lens barrel.

[0034] In other words, the production line of this solution can not only process conventional lenses, but also complete the assembly of special lenses with collars, making the product widely applicable.

[0035] Reference Appendix Figure 1 , 2 As a preferred embodiment of this utility model, the number of single assembly machine components (20) included in the assembly line (2) is set to at least 4 units. Each assembly machine component (20) is connected in a parallel manner to form a modular assembly form. Each unit is a fully functional independent assembly station. It can be understood that the number of 4 assembly machines can meet the assembly requirements of common single and multi-layer lens camera modules on the market.

[0036] Specifically, for example, when assembling a three-layer lens module, the first three assembly machines can be used to assemble each layer of lens (and spacers) in sequence, while the fourth assembly machine can be used as a backup station for producing more complex products, conducting quality re-inspection, or taking over the work when one of them is under maintenance. The number of assembly machines can be freely increased or decreased according to the actual product process complexity, and it has high scalability.

[0037] Reference Appendix Figure 5 As a preferred embodiment of the present invention, the assembly machine component (20) in this solution can be enclosed by an existing conventional frame (21), and universal wheels for pushing can be provided at the bottom to facilitate the movement and assembly of multiple assembly machine components (20).

[0038] Reference Appendix Figure 4 As a preferred embodiment of this utility model, both the Z-axis (2005) and X-axis (2001) of lens assembly adopt a multi-axis motion structure directly driven by a linear servo motor. The lens achieves high positioning accuracy and stability during material picking, movement and assembly, thereby improving the alignment and assembly speed and accuracy of the lens and lens barrel.

[0039] Of course, it is understandable that this is only a preferred example of a driving method. Depending on different cost and control requirements, these axes can also be implemented using other driving methods, such as using a rotary servo motor with a ball screw, or using a high-precision linear module with a stepper motor, all of which can complete the corresponding lens transfer and assembly functions.

[0040] Reference Appendix Figure 4 As a preferred embodiment of this utility model, the lens assembly Z-axis (2005) and lens assembly X-axis (2001) are both picked up by a negative pressure suction head. The lens is picked up by vacuum adsorption, avoiding scratches or indentations on the lens surface. It is especially suitable for handling precision parts such as optical lenses. At the same time, the negative pressure suction head has a simple structure and is fast.

[0041] Alternatively, other common material handling methods can be used, such as flexible mechanical grippers, or electromagnetic chucks for picking up lenses with metal parts.

[0042] The following points need to be explained:

[0044] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure can be combined with each other.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
