Description

Technical Field

[0001] This utility model relates to the field of lens production equipment technology, and more specifically, to a lens assembly machine. Background Technology

[0002] With the increasing popularity of mobile electronic devices, camera modules used for capturing images are also developing rapidly and are widely used in fields such as medical care, security, and industrial production. Especially in the consumer electronics field, such as the smartphone market, optical lenses with multi-lens combinations have become the mainstream configuration. As a precision optical device, the assembly quality of the lens directly affects the quality of image capture. Therefore, manufacturers have equipped themselves with various assembly equipment to improve assembly accuracy and efficiency.

[0003] To address this, Chinese Patent Application No. 202510591676.0 discloses a lens assembly machine and a lens production line. The lens assembly machine includes a feeding module, an angle transfer mechanism, a picking mechanism, and an assembly module. The feeding module is suitable for providing various materials for lens assembly. The angle transfer mechanism includes multiple positioning platforms adapted to different materials. The picking mechanism connects the hook-and-carry mechanism to the angle transfer mechanism and includes a picking turntable, a picking moving module, and multiple picking nozzles. The picking turntable is rotatably connected to the picking moving module and can move under the drive of the picking moving module. The picking nozzles at different positions are adapted to one of the various materials. The assembly module is suitable for assembling lenses. This solution can improve the integration of the picking mechanism and effectively reduce the volume occupied by material handling-related structures in the lens assembly machine. However, it cannot precisely adjust the position of the lens and lens barrel, and the assembly accuracy needs further improvement.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] The problem solved by this invention is that the existing lens assembly machine has an unreasonable structure, which makes it impossible to assemble multiple different parts at a single mounting position, resulting in a large space occupation and the need to further improve the assembly accuracy.

[0006] To address the aforementioned problems, this utility model provides a lens assembly machine, comprising a base plate and a hopper, the hopper being located above the base plate. A third Y-axis transport module is mounted on the base plate for transferring lenses from the hopper to a first position. The base plate is also equipped with a gantry and a correction assembly. A first transport module moving along the X-axis is mounted on the gantry, and the first transport module is equipped with an assembly Z-axis assembly for transferring lenses from the first position to a second position and moving them downwards to assemble them with the lens barrel. The correction assembly is located along the movement path of the first transport module and is used to correct the position of the lenses.

[0007] This application utilizes a correction component to finely adjust the position of the lens, ensuring that the assembled Z-axis assembly applies force directly to the center of the lens. This ensures that a uniform force is applied 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.

[0008] Preferably, the correction assembly includes opposing grippers that are driven by a cylinder to move closer or further apart. This arrangement uses the grippers to hold the lens and corrects the lens in the X-axis direction. Then, the first transport module 21 is adjusted so that the suction pen is aligned with the center of the lens to achieve correction in the Y-axis direction.

[0009] Preferably, the lens assembly machine further includes a left vision component, which is fixed on the gantry frame and used to identify the coordinate position of the lens on the tray. The left vision component then uses the third Y-axis transport module to ensure that the lens to be assembled is always on the movement path of the first transport module. This configuration allows the left vision component to identify the position of the lens in the tray and the third Y-axis transport module to dynamically adjust it, thereby ensuring continuous production.

[0010] Preferably, a first Y-axis transport module is provided on the base plate, which is perpendicular to the gantry and used to transport the lens barrel before and after assembly between the second and third positions. The lens assembly machine also includes a Z-axis transport module, which is fixed on the first transport module and used to transport the lens barrel to be assembled to the third position or to output the assembled lens from the third position to the next process. This configuration enables automatic transport of the lens barrel and makes full use of the space on the base plate, improving the automation level of lens assembly.

[0011] Preferably, the base plate is equipped with a second Y-axis transport module, which is arranged parallel to the first Y-axis transport module and is 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 is in the second position, the second Y-axis transport module is in the third position, which can shorten the operation time of the assembly process and greatly improve the assembly efficiency.

[0012] Preferably, the lens assembly machine further includes a right vision component, which is fixed to the gantry and 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. Adjustment is made by the corresponding first or second Y-axis transport module to position the lens barrel to be assembled on the movement path of the first transport module. This configuration allows multiple lens barrels to be placed simultaneously at the second position, with position identification using the right vision component and dynamic adjustment via the first or second Y-axis transport module, significantly improving production efficiency, reducing energy consumption, and ensuring production continuity.

[0013] 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 barcode of the lens barrel temporarily placed on the transfer seat. The base plate is provided with a cutting component, which is located on the side of the first Y-axis transport module or the second Y-axis transport module away from the transfer seat.

[0014] Preferably, the lens assembly machine further includes an electrostatic dust removal component, which includes two pillars located on either side of the first Y-axis transport module and the second Y-axis transport module, respectively. An electrostatic eliminator is disposed between the pillars. This arrangement positions the electrostatic eliminator 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.

[0015] Preferably, the lens assembly machine further includes a pen holder for accommodating multiple pens. The pen holder is located on one side of the hopper and fixed to the third Y-axis transport module. The pen holder is equipped with a locking component for selectively limiting the position of the pens. The assembly Z-axis assembly includes a mounting base for magnetically attaching with the pens. This configuration enables automatic switching of pens, 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.

[0016] Preferably, the base plate is provided with an NG tray, which is located on the side of the gantry away from the hopper, and is used to hold lenses that are facing the wrong direction.

[0017] Compared with the prior art, the lens assembly machine described in this utility model embodiment has the following beneficial effects: 1) The position of the lens to be assembled is adjusted by the calibration component to ensure that the force is applied evenly to the lens through the assembly Z-axis assembly when assembling with the lens barrel, resulting in stable, reliable and high-precision assembly; 2) The position of the lens to be transported is adjusted by the left vision component and the right vision component to ensure that it is always on the movement path of the assembly Z-axis assembly, further improving assembly efficiency; 3) By setting up a suction pen library, the suction pen for picking up the lens can be switched, thereby completing the assembly of multiple different lenses in one station, with a wide range of applications.

[0027] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0028] like Figure 1-5 As shown, a lens assembly machine includes a base plate 1 and a hopper 3. 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 base plate 1 is provided with a gantry 2 and a correction assembly 4. A first transport module 21 that moves along the X-axis is provided on the gantry 2. 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 assembly 4 is located on the movement path of the first transport module 21 and is used to correct the position of the lens.

[0029] This application utilizes the correction component 4 to fine-tune 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.

[0030] 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 is aligned with the center of the lens to achieve correction in the Y-axis direction.

[0031] 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.

[0032] 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.

[0033] As an example of this utility model, a first Y-axis transport module 5 is provided on the base plate 1. The first Y-axis transport module 5 is arranged perpendicular to the gantry 2 and is used to transport the lens barrel before and after assembly between the second position and the third position. The lens assembly machine also includes a Z-axis transport module 22, which is fixed on the first transport module 21 and is used to transport the lens barrel to be assembled to the third position or to output the assembled lens from the third position to the next process.

[0034] This setup enables automatic transport of the lens barrel and fully utilizes the space on the base plate 1, improving the automation level of lens assembly. The Z-axis transport module 22 and the assembled Z-axis assembly 25 can be mounted on the same first transport module 21, or separately 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 setup prevents interference between the assembled Z-axis assembly 25 and the Z-axis transport module 22, resulting in high assembly efficiency.

[0035] Preferably, the base plate 1 is provided with a second Y-axis transport module 6, which is arranged parallel to the first Y-axis transport module 5, and is 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.

[0036] 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.

[0037] As an example of this utility model, a transfer seat 7 and a barcode scanning component 8 are provided on the base plate 1. The barcode scanning component 8 is arranged adjacent to the transfer seat 7 and is used to scan the barcode of the lens barrel temporarily placed on the transfer seat 7. A cutting component 11 is provided on the base plate 1. The cutting component 11 is located on the side of the first Y-axis transport module 5 or the second Y-axis transport module 6 away from the transfer seat 7.

[0038] 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.

[0039] 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.

[0040] As an example of this utility model, the lens assembly machine further includes a pen holder 12 for accommodating multiple pens. The pen holder 12 is located on one side of the material bin 3 and fixed to the third Y-axis transport module 10. The pen holder 12 is equipped with a locking component for selectively limiting the position of the pens. The assembly Z-axis assembly 25 includes a fixing seat for magnetically attaching with the pens. This configuration enables automatic switching of pens, 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.

[0041] 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.

[0042] It should be noted that the electrostatic dust removal assembly 13 also includes a support base 132, which is fixed to the base plate 1 and used to limit the assembly of the support column 135. A height adjustment seat 133 is provided on the top of the support column 135, and a mounting seat 134 is provided on the height adjustment seat 133 for mounting the static eliminator 131. This configuration allows for height adjustment of the static eliminator 131, providing strong adaptability.

[0043] When assembling the lens and lens barrel, the lens barrel is first transferred to the intermediate transfer 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 remains 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, which is then identified by the left vision component 23. The position of the tray is adjusted by the third Y-axis transport module 10 so that the lens to be picked up is always 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 in 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, and then transported to the next process by the Z-axis transport module 22.

[0044] 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.
