Description

[0002] Nowadays, various electronic devices have entered thousands of households. In order to meet people's needs for taking photos and videos of various electronic devices, it is usually necessary to install lenses inside the devices. When installing the lens, the manufacturer needs to focus the lens, that is, use the focusing machine to fine-tune the distance between the lens and the photosensitive element. This allows the focusing surface of the lens to be aligned with the sensing surface of the photosensitive element, so that users can get the best photo or video experience.

[0003] At present, the commonly used focusing method in the industry is still manual focusing. This focusing method will cause the focusing ring to be unable to accurately lock the lens petals, and the lens surface will be scratched during the rotation and locking process. In addition, manual focusing cannot achieve balanced force control during the rotation process. During the focusing and testing process, uneven pressure will cause the test value to change, and accurate focusing cannot be achieved.

To achieve automatic line production, special pick-and-place equipment needs to be customized, which is expensive and cannot meet the design requirements of the factory automatic line.

[0026] Please refer to Figure 1-Figure 2 , Figure 1A top view of an off-line focusing and feeding device provided in an embodiment of the present invention, Figure 2 A stereoscopic diagram of an offline focusing and feeding device provided in an embodiment of the present invention. This embodiment provides an offline focusing and feeding device for supplying lens modules to a focusing machine, comprising a tray 10, a machine table 20, and a feeding mechanism 30, a conveying mechanism 40, a material taking and placing mechanism 50, and a positioning and correction mechanism arranged on the machine table 20, wherein a plurality of lens modules are placed in the tray 10, a plurality of trays 10 are stacked on the feeding mechanism 30, the feeding mechanism 30 is used to separate the trays 10, the conveying mechanism 40 is used to convey the separated trays 10 to a working area, and the positioning and correction mechanism The structure includes an upper vision module 60 and a lower vision module 61, the upper vision module 60 is used to take pictures and locate the lens module in the Tray 10 in the working area, the material picking and placing mechanism 50 takes materials according to the positioning information of the upper vision module 60, the lower vision module 61 is used to take pictures of the lens module taken out by the material picking and placing mechanism 50, the material picking and placing mechanism 50 corrects the angle of the lens module according to the shooting information of the lower vision module 61, and the material picking and placing mechanism 50 is also used to supply the lens module after the angle correction to the focusing machine.

[0027] By using the Tray 10 as a feeding carrier for the lens module, and then using the conveying mechanism 40 to convey the Tray 10 and using the material taking and placing mechanism 50 to place and place materials, the feeding needs of various types of products can be met, and the problems in the prior art such as some products not being suitable for automatic production line operations and low manual operation output of a single focusing machine can be effectively solved. At the same time, the lens module is corrected by the positioning correction mechanism to facilitate automatic focusing of the focusing machine, thereby improving the focusing accuracy and efficiency.

[0028] For details, please refer to Figure 1-Figure 2 , and combined with Figure 3 , Figure 3 A schematic diagram of a feeding mechanism provided in an embodiment of the present invention, wherein the off-line focusing and feeding device includes a first driving component, the feeding mechanism 30 includes a supporting component 31, a tray dividing component, a feeding tray 32 and a conveying component, a plurality of the Tray trays 10 are stacked on the supporting component 31, the tray dividing component is used to separate the bottom Tray tray 10, the first driving component is used to drive the feeding tray 32 to move along the Z axis so that the feeding tray 32 holds the separated Tray tray 10 and places the Tray tray 10 on the conveying component, and the conveying component conveys the Tray tray 10 to the conveying mechanism 40.

[0029] In this embodiment, the supporting component 31 is, for example, a supporting rod, and the corners of the feeding tray 32 have notches. The supporting rod is located at the notches and lifts up multiple stacked Tray trays 10 from the bottom to the top. The tray separation assembly includes, for example, a separation rod and a cylinder. The cylinder drives the separation rod to extend and rest between the bottom Tray tray 10 and the penultimate Tray tray 10 to separate the bottom Tray tray 10, and at the same time, the supporting rod retracts downward so that the separated Tray tray 10 falls on the feeding tray 32, and then the first driving component drives the feeding tray 32 to move along the Z axis to place the Tray tray 10 on the conveying component, and the conveying component conveys the Tray tray 10 to the conveying mechanism 40.

[0030] It should be understood that Figure 1 For example, the X-axis mentioned in this application is the left-right direction, the Y-axis is the up-down direction, the X-axis and the Y-axis are horizontal directions, and the Z-axis is the direction perpendicular to the drawing paper, which can also be understood as the vertical direction.

[0031] Preferably, the conveying component includes a first conveying track and a second conveying track arranged along the Y axis, the first conveying track and the second conveying track are located on the same straight line and have a set spacing, and the first conveying track and the second conveying track are respectively controlled by different motors. By designing the conveying component as two conveying tracks, it is equivalent to having an extra waiting station. When the conveying mechanism 40 does not need the Tray 10, the first conveying track can convey the next Tray 10 to the second conveying track for waiting, and then the first conveying track and the second conveying track are controlled by the motor to suspend operation, thereby improving work efficiency.

[0032] More preferably, the first conveying track and the second conveying track each include two conveyor belts arranged in parallel along the Y-axis, and the distance between the two conveyor belts is greater than the width of the feeding tray 32 and less than the width of the Tray 10. It should be understood that the width here refers to the width of the feeding tray 32 and the Tray 10 along the X-axis direction. Since the distance between the two conveyor belts is greater than the width of the feeding tray 32 and less than the width of the Tray 10, when the first driving component drives the feeding tray 32 to move downward, the two ends of the Tray 10 are respectively mounted on the two conveyor belts, and the feeding tray 32 can directly pass through the gap between the two conveyor belts and continue to move downward.

[0033] Please continue to refer to Figure 1-Figure 2 , and combined with Figure 4 , Figure 4A schematic diagram of a conveyor provided in an embodiment of the present invention, wherein the off-line focusing and feeding device includes a second driving component, the conveying mechanism 40 includes a transfer frame, the transfer frame is provided with a receiving track 41 parallel to the Y-axis, the receiving track 41 is used to receive the Tray plate 10 after the feeding mechanism 30 separates the trays, and the second driving component 80 is used to drive the transfer frame to move along the X-axis to transport the Tray plate 10 to the working area.

[0034] In this embodiment, the receiving track 41 is also two conveyor belts arranged in parallel along the Y-axis. When the Tray 10 needs to be received, the second driving component 80 drives the intermediate transfer frame to move along the X-axis to align the receiving track 41 with the second conveying track, so that the Tray 10 can move onto the receiving track 41, and then the second driving component 80 drives the intermediate transfer frame to move along the X-axis to transport the Tray 10 to the working area.

[0035] Preferably, the conveying mechanism 40 further includes a clamping component 42 disposed at both ends of the intermediate transfer rack, and when the Tray 10 is completely moved onto the receiving track 41, the clamping component 42 is used to clamp and fix the Tray 10 onto the intermediate transfer rack. In this embodiment, the clamping component 42 includes, for example, a clamping block and a cylinder, and the cylinder drives the clamping block to move vertically to clamp and fix the Tray 10 onto the intermediate transfer rack (receiving track 41).

[0036] Please continue to refer to Figure 1 The off-line focusing and feeding device includes a third driving component 81 and a fourth driving component 82. The material picking and placing mechanism 5 includes a material picking and placing body and an adsorption component. The upper visual module 60 and the adsorption component are both installed on the material picking and placing body. The third driving component 81 and the fourth driving component 82 are used to drive the material picking and placing body to move along the X-axis or the Y-axis respectively, so as to move the material picking and placing body to the working area or the lower visual module 61. The adsorption component is used to pick up materials according to the positioning information of the upper visual module 60.

[0037] Since the upper vision module 60 is installed on the material taking and placing body, the material taking and placing body and the upper vision module 60 can move synchronously along the X-axis or the Y-axis. Since a plurality of lens modules are placed in the Tray 10, the upper vision module 60 is used to position the lens modules in the Tray 10, so that the adsorption component can take materials (take out the positioned lens modules) according to the positioning information of the upper vision module 60, and this process can be completed with the assistance of the control system.

[0038] Preferably, the adsorption component includes at least one vacuum suction nozzle, and the material picking and placing mechanism 50 also includes at least one fifth driving component, and the fifth driving component corresponds to the vacuum suction nozzle one by one and is used to drive the corresponding vacuum suction nozzle to move along the Z axis to adsorb the lens module. It should be understood that the adsorption component provided in this embodiment may include one vacuum suction nozzle, or two or even more vacuum suction nozzles, and this application does not impose any restrictions on this. Multiple vacuum suction nozzles can be set according to production requirements, so that multiple focusing machines can be fed at the same time, thereby improving the focusing efficiency of the lens module.

[0039] In this embodiment, the lower visual module 61 is located below the lens module and is used to take pictures of the lower surface of the lens module. The offline focusing and feeding device also includes at least one sixth driving component, which corresponds one-to-one to the vacuum suction nozzle and is used to drive the corresponding vacuum suction nozzle to rotate around the Z axis to correct the angle of the lens module.

[0040] After the lens module is calibrated, the material taking and placing mechanism 50 feeds materials to the focusing machine under the driving of the third driving component 81 , the fourth driving component 82 and the fifth driving component.

[0041] In this embodiment, the off-line focusing and feeding device further includes a defective product station 70 for placing unqualified lens modules.

[0042] In this embodiment, the first driving component, the second driving component 80, the third driving component 81, the fourth driving component 82 and the fifth driving component can adopt conventional driving mechanisms in the field, such as a stepping motor screw transmission mechanism, and this application does not impose any restrictions on this.

[0043] Please continue to refer to Figure 1 The off-line focusing and feeding device also includes a material receiving mechanism 90. The material taking and placing mechanism 50 places the lens module after the focusing machine has completed focusing into the Tray 10. When the lens modules of the Tray 10 have completed focusing, the conveying mechanism 40 conveys the Tray 10 to the material receiving mechanism 90. The material receiving mechanism 90 is also used to stack multiple Trays 10.

[0044] In this embodiment, the structure of the receiving mechanism 90 is basically the same as that of the feeding mechanism 30, and the movement process of each component is opposite, except that the feeding mechanism 30 is mainly used to separate trays and transport the separated Tray trays 10 to the conveying mechanism 40, while the receiving mechanism 90 receives the Tray trays 10 recovered by the conveying mechanism 40 and stacks the Tray trays 10. This application will not elaborate on this.

[0045] In summary, an embodiment of the present invention provides an offline focusing and feeding device, which adopts a Tray as a feeding carrier for the lens module, and then uses a conveying mechanism to convey the Tray and uses a material picking and unloading mechanism to pick up and unload materials, thereby meeting the feeding needs of various different types of products, and effectively solves the problems in the prior art that some products are not suitable for automatic production line operations and the output of a single focusing machine is low due to manual operation. At the same time, the lens module is corrected by a positioning correction mechanism to facilitate automatic focusing of the focusing machine, thereby improving the focusing accuracy and efficiency.

[0046] The above is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which does not depart from the content of the technical solution of the present invention and still falls within the protection scope of the present invention.
