Description

Technical Field

[0001] This utility model relates to the field of lens module processing, and in particular to a multi-axis inline plate-stacking machine in an assembly line. Background Technology

[0002] Currently, in the processing technology of camera modules, especially for highly automated processing lines, there is usually an automatic tray-laying device at the front end. It is mainly used to automatically organize and fill various materials of the camera into trays to facilitate subsequent automated processing.

[0003] The existing tray-stacking equipment mainly includes a loading and unloading mechanism and a central robotic tray-stacking structure. During operation, the material is loaded from one side, positioned by a vision system moving back and forth, and then the central robotic arm places the various components of the module into the tray for subsequent processing. Finally, the material is unloaded through the unloading station.

[0004] However, the traditional loading and unloading mechanism described above operates in a straight line, relying primarily on the continuous movement of a vision positioning device for positioning. This vision positioning is finely adjusted before operation, and constant movement affects its accuracy. Adjustments are only made after numerous rejections (NGs) occur. Furthermore, the existing loading and unloading system lacks a floating structure, making it incompatible with adjacent equipment of various heights and specifications, resulting in poor adaptability and often requiring large-scale modifications.

[0005] In view of this, this technical solution proposes a multi-axis inline tray-loading machine within an assembly line. It employs a fixed optical positioning mechanism, achieving precise positioning only through planar displacement of the lower material transfer component, without requiring frequent adjustments to the optical positioning device itself. It also features a floating loading and unloading structure, enhancing its adaptability. Utility Model Content

[0006] 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 a multi-axis inline tray-loading machine within an assembly line, which aims to solve the problems of short-term accuracy maintenance of visual positioning and poor adaptability of loading and unloading structures in existing automatic tray-loading methods.

[0007] To achieve the above objectives, this utility model provides a multi-axis inline tray-stacking machine within an assembly line, comprising a tray-stacking machine body consisting of a feeding assembly, an optical positioning assembly, a material transfer mechanism, a tray-stacking mechanism, and a discharging assembly. The feeding assembly includes a slide rail arranged along the Z-axis, and fixed seats and fixed plates respectively fixed to both sides of the slide rail. The bottom of the fixed plate moves on the slide rail via a feeding drive. A material hopper is provided on the fixed plate. The optical positioning assembly is located near the feeding assembly and includes a gantry frame and an upper camera disposed on the top of the gantry frame. The material transfer mechanism includes a material transfer spindle arranged along the X-axis. The main body of the transfer spindle is located below the gantry frame, with one end close to the loading assembly. The transfer spindle is vertically equipped with an alignment shaft, and the alignment shaft is equipped with a tray plate that runs along the Y-axis. The tray mechanism includes a transverse guide rail located behind the optical positioning assembly. The transverse guide rail is equipped with a slider driven by a lifting motor. The slider is equipped with a picking head, which dynamically corresponds to the tray plate passing below. The unloading assembly includes a tray carrier plate located at the other end of the transfer spindle. An unloading guide rail is formed in the middle of the tray carrier plate. The two sides of the tray carrier plate are connected to the lifting drive at the bottom via connecting rods.

[0008] As a further embodiment of this invention, the feeding assembly also includes a height measuring rod disposed near the hopper.

[0009] As a further embodiment of this invention, a vibrating disc for initial screening of each component is provided near the feeding assembly.

[0010] As a further embodiment of this invention, the optical positioning assembly also includes a slide block disposed on the top of the gantry frame, and the upper camera is fixed on the slide block.

[0011] As a further improvement of this utility model, the hopper is a magazine-type hopper structure.

[0012] As a further embodiment of this utility model, the feeding component, optical positioning component, material transfer mechanism, tray-mounting mechanism, and unloading component are arranged on a machine platform, and the bottom of the machine platform is supported by a frame.

[0013] As a further embodiment of this utility model, the main body of the tray-stacking machine is provided with an assembly unit on one side near the feeding component. The assembly unit is an assembly equipment module composed of various assembly components, and a dispensing machine is provided on the other side of the assembly unit.

[0014] The beneficial effects of this utility model are as follows: In this fixed optical positioning assembly, the upper camera remains stationary. The material tray is moved through the camera for detection only by the material transfer mechanism's main shaft moving along the X-axis and the material tray plate moving along the Y-axis. This avoids the accuracy degradation problem caused by the frequent movement of traditional visual positioning devices, allowing the optical positioning accuracy to be maintained stably for a long time. This reduces the number of defective products caused by positioning deviations and the frequency of downtime for recalibration during production, thereby improving production reliability and efficiency.

[0015] On the other hand, the floating feeding component drives the fixed plate to adjust up and down along the slide rail through the feeding drive, and the unloading component raises and lowers the material tray through the lifting drive and the connecting rod. This allows the feeding and unloading heights to be flexibly adapted to adjacent equipment of different specifications. It can achieve smooth connection with the preceding and following processes without large-scale structural modifications, which greatly enhances the compatibility of the entire tray machine on the production line.

[0016] This technical solution maintains high-precision operation while also offering greater flexibility and adaptability, effectively improving the overall smoothness of automated production line operation and production efficiency. Attached Figure Description

[0031] Please see the appendix Figure 1-10 , The multi-axis inline tray-stacking machine in this scheme is mainly composed of a feeding assembly (10), an optical positioning assembly (11), a material transfer mechanism (12), a tray-stacking mechanism (13), and a discharging assembly (14). The feeding assembly (10) includes a slide rail (101) arranged vertically (i.e., along the Z-axis). A fixed base (100) and a movable fixed plate (102) are fixed to both sides of the slide rail (101). The bottom of the fixed plate (102) is connected to and controlled by a feeding drive (104), allowing it to move up and down along the slide rail (101). A hopper (103) for storing components to be processed is installed on the fixed plate (102). The optical positioning assembly (11) is installed near the feeding assembly (10). Its main body is a gantry frame (110), and an upper camera (112) is fixedly installed on the top of the gantry frame (110) for performing visual positioning. The material transfer mechanism (12) includes a material transfer spindle (120) arranged in the horizontal longitudinal direction (X-axis direction). The main body of the spindle is located below the gantry frame (110) of the optical positioning assembly (11), and one end of the spindle extends to a position close to the loading assembly (10). A alignment shaft (121) is vertically mounted on the material transfer spindle (120). A tray support plate (122) that can move in the horizontal transverse direction (i.e., Y-axis direction) is mounted on the alignment shaft (121) for carrying and transporting the tray. The tray-stacking mechanism (13) is located behind the optical positioning assembly (11). It includes a transverse guide rail (130), on which a slider (132) driven by a lifting motor (131) is mounted. The slider (132) is equipped with a material-picking head (133), which can dynamically align with the material tray (122) passing below and perform material picking and placing actions during operation. The unloading assembly (14) is located at the other end of the transfer spindle (120) and includes a material tray carrier plate (140). A unloading guide rail (141) for the material tray to slide out is opened in the middle of the material tray carrier plate (140). The two sides of the material tray carrier plate (140) are connected to the lifting drive (143) installed at the bottom through connecting rods (142), so that the entire unloading part can float up and down.

[0032] Specifically, in this solution, the optical positioning component (11) is a fixed structure. The material tray is driven to complete the positioning by moving the material transfer main shaft (120) of the lower material transfer mechanism (12) in the X-axis and cooperating with the alignment shaft (121) and the material tray plate (122) in the Y-axis. This avoids the accuracy change problem caused by the frequent movement of the visual positioning device itself in the traditional method, so that the positioning accuracy can remain stable for a long time, reducing the frequency of defective products and downtime calibration caused by accuracy drift, thereby improving the overall reliability and efficiency of production.

[0033] Furthermore, both the loading assembly (10) and the unloading assembly (14) adopt a floating structure. The loading assembly (10) drives the fixed plate (102) and the hopper (103) to adjust up and down along the Z-axis slide rail (101) through the loading drive (104), which can flexibly adapt to different material heights or changes in the height of the docking equipment. The unloading assembly (14) uses the lifting drive (143) at the bottom in conjunction with the connecting rod (142) to enable the material tray carrier plate (140) to be adjusted in height, so as to smoothly match the inlet height of the subsequent process equipment (such as the assembly unit (2)). Through the floating loading and unloading structure, the height adaptability of the tray machine to the upstream and downstream links of the production line is realized. Without the need for large-scale structural modifications to adjacent equipment of different heights, rapid docking can be achieved, which improves the flexibility and integration of the production line.

[0034] Overall, this solution combines fixed optical positioning with floating loading and unloading, ensuring continuous high-precision positioning while significantly improving the equipment's adaptability to diverse production environments and the smoothness of overall operation.

[0035] Optionally, in this solution, the optical positioning component (11) includes not only the upper optical CCD camera, but also the same and corresponding lower camera at the bottom. The principle is to keep the entire optical positioning component (11) stationary and move it only through the material transfer component.

[0036] Reference Appendix Figure 5 As a preferred embodiment of this utility model, in this solution, the feeding component (10) is provided with a height measuring rod (105) near the silo (103). The height measuring rod (105) is installed on the side of the silo (103) to detect the height of the material stack in the silo (103) in real time. By cooperating with the feeding drive (104) of the floating feeding component (10), the height data of the height measuring rod (105) guides the fixed plate (102) to automatically adjust the lifting position along the slide rail (101) so as to match the current height of the material in the silo (103) and realize the adaptive feeding process, thereby improving the overall automation level of feeding.

[0037] Of course, alternatively, using a height measuring rod (105) is only a preferred implementation. In fact, other height detection alternatives can also be used, such as installing a laser range sensor near the silo (103), or using the upper camera (112) in the optical positioning component (11) to estimate the material height through visual analysis, which can also achieve the effect of assisting floating material feeding.

[0038] Reference Appendix Figure 3As a preferred embodiment of the present invention, a vibratory feeder (106) is provided near the feeding component (10). The vibratory feeder (106) is independently installed on the side or in front of the hopper (103) to receive scattered components and perform preliminary orientation and screening through vibration, so that only components that meet the standards are orderly transported to the subsequent hopper (103) or feeding station.

[0039] Reference Appendix Figure 6 As a preferred embodiment of the present invention, the optical positioning component (11) of the present invention has a slide (111) on the top of the gantry frame (110).

[0040] The slide (111) is an alternative structure for adjusting the camera because, in this design, the camera does not require frequent adjustments, but temporary adjustments are needed during installation or maintenance. In other words, the slide (111) allows the upper camera (112) to make fine adjustments to its sliding position within a limited range at the top of the gantry frame (110). It maintains the camera's absolute fixation during operation to ensure long-term positioning accuracy, while also allowing for adjustments during initial installation, debugging, or subsequent maintenance. The camera can be quickly calibrated without disassembly, offering high flexibility.

[0041] Reference Appendix Figure 5 As a preferred embodiment of this utility model, the hopper (103) in the scheme adopts a clip-type hopper structure, which can be loaded and unloaded as a whole. It is installed on the fixing plate (102) of the feeding component (10), which facilitates the quick replacement of the full or empty hopper unit, reduces downtime during material change, improves the continuity of the feeding process and the overall production efficiency. The clip-type hopper has a compact structure and is easy to manage.

[0042] Of course, depending on actual production needs, the silo (103) can also adopt other structures, such as a liftable multi-layer material rack, or a circulating material silo with a conveyor belt.

[0043] Reference Appendix Figure 2 , 4 1. As a preferred embodiment of the present invention, the feeding component (10), optical positioning component (11), material transfer mechanism (12), tray swivel mechanism (13) and unloading component (14) of the present solution are integrated and installed on a unified machine base (15). The bottom of the machine base (15) is supported by the frame (16). The entire tray swivel machine body (1) has a compact structure, which facilitates overall transportation and production line layout.

[0044] Reference Appendix Figure 10As a preferred embodiment of this utility model, in this solution, the entire tray-stacking machine body (1) can form a highly automated production line with the assembly machine and the dispensing machine (3). The assembly machine group (2) is a modular assembly equipment composed of multiple independent assembly units. The material trays arranged and unloaded by the tray-stacking machine are seamlessly connected to the assembly machine group (2) through the adjustable unloading component (14) for subsequent assembly, and then transferred to the dispensing machine (3) to complete the glue application, thereby forming a highly automated production line, which greatly improves efficiency.
