[0009] Preferably, the base plate is provided with a transfer seat and a barcode scanning component. The barcode scanning component is arranged adjacent to the transfer seat and is used to scan the lens barrel temporarily placed on the transfer seat. The base plate is provided with a cutting component for temporarily placing the assembled lens. The cutting component is located on the side of the first Y-axis transport module away from the transfer seat.

[0010] Preferably, the lens assembly machine further includes a right vision component, which is fixed on the gantry and is used to identify the coordinate position of the lens barrel on the first Y-axis transport module and / or the second Y-axis transport module, and to adjust the lens barrel to be assembled so that it is on the movement path of the first transport module by the corresponding first Y-axis transport module or the second Y-axis transport module.

[0011] Preferably, the base plate is provided with a hopper and a correction assembly. The hopper is located above the base plate. A third Y-axis transport module is provided on the base plate for transferring the lens in the hopper to a first position. An assembly Z-axis assembly is provided on the first transport module for transferring the lens in the first position to a second position and moving it downward to achieve assembly with the lens barrel. The correction assembly is located on the movement path of the first transport module and is used to correct the position of the lens.

[0015] Preferably, the pen holder includes a fixed plate fixedly connected to the third Y-axis transport module, a mounting base is provided on the fixed plate, and a plurality of mounting holes are provided on the upper end surface of the mounting base for placing the pen; the pen holder also includes a locking component, which is located above the mounting base and is used to selectively limit the position of the pen.

[0016] Compared with the prior art, the lens assembly machine described in this utility model embodiment has the following beneficial effects: 1) By setting a cutting component to place the assembled lens and a sliding component to transport the lens to the next process direction, the requirements for the distance between the lens and the connecting equipment are low, and it can be easily adapted to the existing production process, so that the lens assembly machine can be used alone or in series with other equipment, and has a wide range of applications; 2) By setting a pen suction magazine, it is possible for a single machine to assemble different parts at the same time.

[0028] like Figure 1-6As shown, a lens assembly machine includes a base plate 1 and a cutting assembly 11. The base plate 1 is equipped with a gantry frame 2, and the gantry frame 2 is equipped with a first transport module 21 that moves along the X-axis and a Z-axis transport module 22. The Z-axis transport module 22 is fixed on the first transport module 21 and is used to transfer the assembled lens from a third position to the cutting assembly 11. The cutting assembly 11 is located at the edge of the base plate 1 and includes a sliding assembly 112. The sliding assembly 112 can slide along the X-axis to adjust the coordinate position of the lens.

[0029] This application uses a cutting component 11 to place the assembled lens and a sliding component 112 to transport the lens to the next process. It has low requirements for the spacing between the lens and the connected equipment, and can be easily adapted to existing production processes. This allows the lens assembly machine to be used alone or in series with other equipment, and has a wide range of applications.

[0030] As an example of this utility model, the cutting assembly 11 further includes a base plate 111, a rotating seat 113, and a mounting plate 114. The mounting plate 114 is fixed on the base plate 111 and is arranged adjacent to the rotating seat 113. A detection module 115 is provided on the mounting plate 114 for detecting whether material is placed on the rotating seat 113. This arrangement can improve the automation level of the equipment and stably feed material to the next process.

[0031] As an example of this utility model, the lens assembly machine further includes a first Y-axis transport module 5 and a second Y-axis transport module 6 arranged in parallel. The first Y-axis transport module 5 and the second Y-axis transport module 6 are arranged perpendicular to the gantry 2 and are used to transport the lens barrel before and after assembly between the second position and the third position. This arrangement can significantly improve the assembly efficiency of the lens assembly machine. Specifically, when the first Y-axis transport module 5 is in the second position, the second Y-axis transport module 6 is in the third position, which can shorten the operation time of the assembly process and greatly improve the assembly efficiency.

[0032] Preferably, the base plate 1 is provided with a transfer seat 7 and a barcode scanning component 8. The barcode scanning component 8 is arranged adjacent to the transfer seat 7 and is used to scan the lens barrel temporarily placed on the transfer seat 7. The base plate 1 is provided with a cutting component 11 for temporarily placing the assembled lens. The cutting component 11 is located on the side of the first Y-axis transport module 5 away from the transfer seat 7.

[0033] The lens barrel is mounted onto the transfer station 7 via the Z-axis transport module 22, and the barcode scanner 8 scans the barcode. Then, the lens barrel is transferred to a third position via the Z-axis transport module 22. The first Y-axis transport module 5 or the second Y-axis transport module 6 then transports the lens barrel from the third position to a second position, where the lens is assembled via the Z-axis assembly 25. Afterward, the lens is transported to a third position via the first Y-axis transport module 5 or the second Y-axis transport module 6, and the assembled lens is transferred to the cutting assembly 11 via the Z-axis transport module 22 for further transport to the next workstation. The specific structures of the transfer station 7 and the barcode scanner 8 are existing technologies and will not be described in detail here.

[0034] Preferably, the lens assembly machine further includes a right vision component 24, which is fixed to the gantry 2. The right vision component 24 identifies the coordinate position of the lens barrel on the first Y-axis transport module 5 and / or the second Y-axis transport module 6, and adjusts it via the corresponding first Y-axis transport module 5 or second Y-axis transport module 6 to position the lens barrel to be assembled on the movement path of the first transport module 21. This configuration allows multiple lens barrels to be placed simultaneously at the second position, with position identification using the right vision component 24 and dynamic adjustment via the first Y-axis transport module 5 or second Y-axis transport module 6, significantly improving production efficiency, reducing energy consumption, and ensuring production continuity.

[0035] As an example of this utility model, the base plate 1 is provided with a hopper 3 and a correction component 4. The hopper 3 is partially located above the base plate 1. A third Y-axis transport module 10 is provided on the base plate 1 for transferring the lens in the hopper 3 to a first position. The first transport module 21 is provided with an assembly Z-axis assembly 25 for transferring the lens in the first position to a second position and moving it downward to achieve assembly with the lens barrel. The correction component 4 is located on the movement path of the first transport module 21 and is used to correct the position of the lens.

[0036] This application utilizes the correction component 4 to finely adjust the position of the lens, so that the assembled Z-axis assembly 25 applies force directly to the center of the lens, thereby ensuring that the force is applied evenly to the lens during assembly with the lens barrel, resulting in stable, reliable, and highly accurate assembly; the overall structure is compact and occupies little space.

[0037] As an example of this utility model, the correction component 4 includes opposing grippers 42, which are driven by a cylinder to move closer or further apart. This arrangement uses the grippers 42 to hold the lens, thereby achieving correction of the lens in the X-axis direction. Then, the first transport module 21 is adjusted so that the suction pen 124 is aligned with the center of the lens to achieve correction in the Y-axis direction.

[0038] The Z-axis transport module 22 and the assembled Z-axis assembly 25 can be mounted on the same first transport module 21, or they can be mounted on different first transport modules 21. As an example of this invention, the gantry 2 is provided with two first transport modules 21. The Z-axis transport module 22 is fixed on one of the first transport modules 21, and the assembled Z-axis assembly 25 is fixed on the other first transport module 21. The Z-axis transport module 22 and the assembled Z-axis assembly 25 are located on opposite sides of the gantry 2. This arrangement ensures that the movement between the assembled Z-axis assembly 25 and the Z-axis transport module 22 will not interfere, resulting in high assembly efficiency.

[0039] As an example of this utility model, the correction component 4 includes a second pad 46 fixed on the base plate 1. The second pad 46 is provided with a manual displacement platform 45 and a correction clamp adjustment plate 47. The correction clamp adjustment plate 47 is provided with a first pad 44 and a magnetic switch 41. The upper part of the magnetic switch 41 is provided with a body 43. The body 43 is provided with a gripper 42. A speed control valve 48 is provided on one side of the magnetic switch 41. The relevant specific structure is prior art.

[0040] As an example of this invention, the lens assembly machine further includes a left vision component 23, which is fixed to the gantry 2. The left vision component 23 identifies the coordinate position of the lenses on the tray and ensures that the lenses to be assembled are always on the movement path of the first transport module 21 via the third Y-axis transport module 10. This setup allows the left vision component 23 to identify the position of the lenses in the tray and the third Y-axis transport module 10 to dynamically adjust it, thereby ensuring continuous production.

[0041] Preferably, the base plate 1 is provided with an NG tray 9, which is located on the side of the gantry 2 away from the hopper 3, and is used to hold lenses that are facing the wrong direction. Since the left vision component 23 can identify the front and back of the lens, and since the number of lenses with the back facing up is extremely small, flipping them would affect assembly efficiency; by temporarily storing them in the NG tray 9 for recycling, assembly efficiency and accuracy can be greatly improved.

[0042] As an example of this utility model, the lens assembly machine also includes a pen holder 12 for accommodating multiple pens 124. The pen holder 12 is located on one side of the hopper 3 and fixed to the third Y-axis transport module 10. The assembly Z-axis assembly 25 cooperates with the pen holder 12 to replace the pens 124. This configuration enables automatic switching of the pens 124, thereby meeting the assembly requirements of different lenses and allowing the assembly of different lenses using a single assembly machine, further expanding the application range of the equipment.

[0043] As an example of this utility model, the pen holder 12 includes a fixing plate 121 fixedly connected to the third Y-axis transport module 10. A mounting base 122 is provided on the fixing plate 121, and multiple mounting holes 1221 are provided on the upper surface of the mounting base 122 for placing pens 124. The pen holder 12 also includes a locking assembly 123 located above the mounting base 122 for selectively limiting the position of the pens 124. This configuration allows the pen holder 12 to accommodate multiple different pens 124, which can be switched by cooperating with the locking assembly 123 to achieve the picking and assembly of different lenses or other fabrics in the hopper 3.

[0044] Specifically, when the suction pen 124 needs to be replaced, firstly, the position of the suction pen magazine 12 is adjusted using the third Y-axis transport module 10 so that the assembled Z-axis assembly 25 is aligned with the mounting hole 1221. At the same time, the locking component 123 is in the open state. The assembled Z-axis assembly 25 moves downward so that the suction pen 124 is inserted into the mounting hole 1221. Then, the locking component 123 is locked to limit the suction pen 124. Afterward, as the assembled Z-axis assembly 25 moves upward, the suction pen 124 overcomes the magnetic attraction and separates from the assembled Z-axis assembly 25. Then, the position of the suction pen magazine 12 is adjusted using the third Y-axis transport module 10 so that the assembled Z-axis assembly 25 is aligned with the suction pen 124 to be replaced. Then, it moves downward while the locking component 123 is opened again. The assembled Z-axis assembly 25 is assembled with the suction pen 124 by magnetic attraction, thereby completing the replacement of the suction pen 124.

[0045] As an example of this utility model, the locking assembly 123 includes a first limiting plate and a second limiting plate disposed opposite to each other. The first limiting plate and the second limiting plate move closer to each other or further apart through a driving assembly to selectively limit the suction pen 124. The first limiting plate and the second limiting plate have clearance portions corresponding to the mounting hole 1221. This arrangement has a simple structure, and multiple suction pens 124 can be limited by a single locking assembly 123. It has a compact structure and high space utilization.

[0046] As an example of this utility model, the lens assembly machine further includes an electrostatic dust removal assembly 13, which includes two support pillars 135 located on either side of the first Y-axis transport module 5 and the second Y-axis transport module 6, respectively. An electrostatic eliminator 131 is disposed between the support pillars 135. This arrangement positions the electrostatic eliminator 131 above the second position, resulting in good dust removal performance and effectively preventing dust from falling in during assembly, thus ensuring high-quality lens assembly.

[0047] As an example of this utility model, the assembled Z-axis assembly 25 includes a vertical plate, a lifting assembly on the vertical plate, and a mounting base on the lifting assembly for magnetically assembling the suction pen 124. A rotating assembly is located above the mounting base to drive the suction pen 124 to rotate. This arrangement facilitates the assembly and replacement of the suction pen 124, and also allows the suction pen 124 to rotate to adjust the orientation of components such as lenses, achieving high assembly precision. It should be noted that the mounting base is connected to a vacuum pipe for adsorbing the lenses and other fabrics via the suction pen 124; its specific structure is existing technology and will not be described further here.

[0048] When assembling the lens with the lens barrel, the lens barrel is first transferred to the intermediate transition seat 7 using the Z-axis transport module 22 and scanned by the barcode scanner 8 to record relevant information. Then, the lens barrel is transported to the third position of either the first Y-axis transport module 5 or the second Y-axis transport module 6 using the Z-axis transport module 22, and then transferred to the second position using either the first Y-axis transport module 5 or the second Y-axis transport module 6. The right vision component 24 ensures that the lens barrel to be assembled is always on the movement track of the assembled Z-axis assembly 25. Simultaneously, the third Y-axis transport module 10 transfers the material tray from the material bin 3, and the left vision component 23 identifies the position of the material tray and adjusts the third Y-axis transport module accordingly. The transport module 10 keeps the lens to be picked up on the movement track of the assembly Z-axis assembly 25. For lenses with the reverse side facing up, they are directly transferred to the NG tray 9. The assembly Z-axis assembly 25 picks up the lens from the tray and transfers it to the calibration component 4 to adjust the coordinate position of the lens. Then, the assembly Z-axis assembly 25 transfers the lens to a position directly above the lens barrel to be assembled and moves it downward to complete the assembly with the lens barrel at the second position. The assembled lens is transferred to the third position by the first Y-axis transport module 5 or the second Y-axis transport module 6. Then, the Z-axis transport module 22 transports the cutting component 11. The cutting component 11 slides a certain distance along the X-axis to facilitate the picking up of the next process.

[0049] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
