Description

Technical Field

[0001] The present invention is applied to the technical field of assembly equipment, and particularly relates to a lens high-speed rotation assembly mechanism and a lens assembly module. Background Art

[0002] In the lens assembly production, the traditional production method is manual assembly and automatic dispensing. The operator manually or using a jig completes the assembly of the lens barrel, lens, spacer and spacer, and the dispensing and UV curing of the lens are completed by a dispensing machine. Pure manual operation is prone to lens wear and tear, and the assembly position of the lens and spacer is skewed. If the force is not properly controlled, the lens may be crushed or the spacer may be deformed and warped. It is difficult to ensure the assembly accuracy and stability of the lens, resulting in product scrapping and reduced product yield, affecting corporate benefits and increasing operator working time and labor intensity.

[0003] In the existing semi-automatic assembly dispensing method, the operator continuously provides each lens assembly machine with materials for the lens barrel, lens, spacer and spacer to be assembled. After the assembly machine completes the assembly of the lens, spacer and spacer, the operator sends them to the dispensing machine to complete the dispensing and UV curing of the lens. Although the operator does not need to manually assemble the lens, spacer and spacer, it requires multiple operators to supply materials in real time, which cannot effectively reduce the labor intensity of the operators. In addition, the assembly of a complete lens requires multiple assembly equipment, and the intermediate handling and transmission will cause secondary pollution and defects, and the assembly efficiency is low.

[0004] Among them, when assembling the lens, it is necessary to ensure the posture and placement accuracy of the lens. The conventional lens pick-up and placement assembly consists of a motor, a lifting cylinder and a vacuum rod, such as the Chinese patent with the publication number CN206813964U, which discloses an automatic rotating lifting and swinging material taking mechanism, in which the motor drives the vacuum rod to rotate through a gear set or a synchronous belt transmission, and a spline structure that cooperates with the gear set is set on the vacuum rod to drive the material to rotate. During the lens installation, the vacuum rod is driven up and down by the lifting cylinder to realize the material taking and placing. Although it can complete the basic requirements such as picking and placing adjustment, due to the fact that there is always a certain deviation in the gear and synchronous belt transmission, it is easy to cause the lens installation accuracy to decrease. There is also a hollow motor as a rotating power source, which is connected by a coupling to solve the problem of rotation accuracy, but due to structural limitations, when it is necessary to perform a lifting action, the coupling cannot meet the lifting function, and the motor and vacuum rod structure are installed on the lifting cylinder at the same time. The active end of the cylinder will be overloaded, resulting in unstable operation and large vibration, which is easy to affect the posture of the material after absorption. Or if larger cylinders and moving mechanisms are needed to improve stability, production costs will increase. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a high-speed rotating assembly mechanism for lenses with small transmission errors in rotation and lifting during rotation adjustment and good structural stability, as well as a lens assembly module with high assembly efficiency and high precision.

[0006] The technical solution adopted by the present invention is: the lens high-speed rotating assembly mechanism includes a mounting seat, a hollow motor, a nozzle assembly, a sliding seat and a lifting power mechanism, the hollow motor and the lifting power mechanism are both fixed on the mounting seat, the sliding seat is slidably matched on the mounting seat along the vertical direction, the nozzle assembly includes a hollow transmission rod, a rotating joint, a lifting and rotating linkage assembly and a vacuum nozzle, the hollow transmission rod passes through and is transmission-connected to the mover of the hollow motor, the rotating joint is connected to the top of the hollow transmission rod, the vacuum nozzle is rotationally matched on the sliding seat, and the vacuum nozzle is connected to the lifting and rotating linkage assembly through the lifting and rotating linkage assembly. The other end of the hollow transmission rod is conductive and transmission connected. The lifting and rotating linkage assembly includes a first coupling, a transmission ring and a second coupling. The first coupling is fixed to the bottom of the hollow transmission rod, and the second coupling is fixed to the top of the vacuum nozzle. At least two groups of guide columns are arranged on the second coupling. The transmission ring is limited on the guide column by a guide sleeve sliding. Several groups of transmission guide blocks and several linkage guide pins are arranged on the top of the transmission ring. The bottom of the first coupling is correspondingly provided with a transmission limit groove adapted to the transmission guide block, and the bottom of the first coupling is also correspondingly provided with a limit guide hole slidingly matched with the linkage guide pin.

[0007] It can be seen from the above scheme that the mounting seat is used to carry the overall mechanism, the hollow motor is used to provide power, and the lifting power mechanism is used to drive the sliding seat and the suction nozzle assembly to rise and fall. Among them, the hollow motor drives the vacuum suction nozzle to rotate through the hollow transmission rod and the lifting and rotating linkage assembly, thereby ensuring that the suction nozzle negative pressure supply is stable and meets the lifting and sucking material requirements. The lifting and rotating linkage assembly is formed by connecting the first coupling, the transmission ring and the second coupling in sequence, and the hollow transmission rod and the vacuum suction nozzle are connected respectively through the first coupling and the second coupling, and then linked through the transmission ring to achieve accurate output of rotational power. The guide column set on the second coupling is slidably matched with the transmission ring, so that the transmission ring can still synchronously transmit the rotational power when it is lifted and lowered relative to the second coupling, and at the same time, it is linked with the first coupling through the linkage guide pin, ensuring that the first coupling, the transmission ring and the second coupling can all be kept at the same angle when extended, thereby maximizing the reduction of rotational errors and improving the linear motion accuracy of the vacuum suction nozzle. The rotation adjustment of the lens is mainly adjusted through the cooperation of the visual camera after the material is picked up. At this time, the lifting power mechanism is in a retracted state, and the transmission ring is tightly fitted with the first coupling. By arranging the transmission guide block on the transmission ring and the transmission limit groove on the first coupling, the force application point is further improved on the basis of a number of the linkage guide pins, thereby effectively improving the transmission stability between the first coupling and the transmission ring.

[0008] A further preferred solution is that the transmission guide block is an isosceles trapezoidal structure, and both sides of the transmission limit groove are provided with guiding inclined surfaces corresponding to and parallel to the inclined surfaces on both sides of the transmission guide block.

[0009] It can be seen from the above scheme that by adopting the isosceles trapezoidal structure design, the first coupling and the transmission ring are automatically guided during the docking process, and the linkage error is automatically corrected to avoid deviation of the linkage guide pin after long-term use.

[0010] A further preferred solution is that a catheter joint is provided at the top of the hollow part of the hollow transmission rod, one end of the catheter joint is connected to the air circuit of the output end of the rotary joint, and the other end of the catheter joint is connected to an air circuit conduit, and the air circuit conduit passes through the first coupling, the transmission ring and the second coupling in sequence and then is connected to the vacuum suction nozzle.

[0011] It can be seen from the above scheme that the traditional transmission method is that the vacuum transmission rod is connected to the mover part of the hollow motor through a spline to achieve up and down sliding, thereby adapting to the material picking action. However, after long-term use, it is easy to wear and cause deviations in the rotation output. By adopting the method of fixedly connecting the hollow transmission rod to the mover of the hollow motor, wear errors are avoided and the service life is improved. In addition, the flexible air conduit is used as a connecting pipe to better adapt to the lifting and lowering deformation during the material picking action, avoid the lifting and lowering action affecting the structural stability of the lens high-speed rotation assembly mechanism, and at the same time reduce the overall weight of the mechanism, reduce costs, and improve operational stability.

[0012] A preferred solution is that the vacuum suction nozzle includes a vacuum tube and an air nozzle, the vacuum tube is rotatably engaged on the sliding seat through at least three sets of bearings, the upper end of the vacuum tube is connected to the air path of the hollow transmission rod, and the air nozzle is fixedly arranged at the lower end of the vacuum tube.

[0013] It can be seen from the above solution that by providing three groups of bearings to cooperate with the vacuum tube, the rotation stability and accuracy of the vacuum tube are effectively improved.

[0014] The lens assembly module includes a machine platform and a carrier transport module, an assembly module, a camera detection module and a feeding module arranged on the machine platform. The carrier transport module drives the carrier loaded with the lens barrel to be transported to the bottom of the assembly module. The camera detection module is arranged above the carrier transport module to perform product positioning detection. The feeding module is arranged on one side of the carrier transport module. The assembly module includes a two-axis moving component. The active end of the two-axis moving component is provided with at least two groups of lens high-speed rotating assembly mechanisms. The two-axis moving component and the camera detection module are both provided with a material tray drag plate that cooperates with the feeding module. The feeding module includes several groups of lifting components and material tray transfer components that cooperate with each other. The active end of the lifting component is loaded with a material magazine. Several material trays are loaded on the material magazine in the vertical direction. The material tray transfer component is provided with a loading slot that is compatible with the material tray. The material tray drag plate cooperates with the card slot on the material tray and drives the material tray to move to the loading slot.

[0015] As can be seen from the above scheme, the carrier transport module realizes automatic handling of the lens barrel carrier and the cache of the lens barrel carrier, and the feeding module realizes automatic tray switching to realize rapid lens feeding. The assembly module is used to take the lens and calibrate it and install it in the lens barrel, and the camera detection module cooperates with the carrier transport module and the feeding module to detect the position of the lens barrel and the lens. Among them, the lens high-speed rotating assembly mechanism is driven by the two-axis moving component to perform lifting and horizontal movement, thereby realizing taking the lens from the feeding module and moving it to the lens barrel carrier for assembly. Through the two-axis moving component and the tray dragging plate on the camera detection module, it is realized to cooperate with the feeding module to put the empty lens carrier back into the magazine, and drag the full lens carrier into the loading slot, thereby realizing rapid switching of the tray, which is convenient for the lens high-speed rotating assembly mechanism to take the material and assemble, and the lifting component switches the docking position of the magazine to realize switching of the taken-out tray.

[0016] A preferred solution is that the camera detection module includes two groups of parallel linear transport mechanisms and two groups of detection camera assemblies, the two groups of detection camera assemblies are respectively arranged on the movable ends of the two groups of linear transport mechanisms, the two groups of detection camera assemblies each include at least two first industrial cameras arranged in parallel, the two groups of linear transport mechanisms are fixed to the machine platform through mounting brackets, the mounting brackets include a connected L-shaped main support frame and an auxiliary bracket, a connecting plate is provided at the movable end of the linear transport mechanism near the feeding module, and the material tray drag plate is arranged on the connecting plate through a lifting cylinder.

[0017] It can be seen from the above scheme that by setting up two groups of the linear transport mechanism, the two groups of detection camera components can be driven to move separately, and the material on the barrel carrier and the material posture on the lens carrier can be detected at the same time, the positioning of the material is completed, and the accuracy of material collection and assembly is ensured. The operation stability of the two groups of the linear transport mechanism is improved by setting up the L-shaped main support frame and the auxiliary support frame. The structural design of the L-shaped main support frame is used to avoid the installation of the feeding module, and the auxiliary support frame is provided to make the connection of the L-shaped main support frame more stable.

[0018] A preferred solution is that the carrier transport module includes a first buffer conveying mechanism, a transfer conveying mechanism, a second buffer conveying mechanism, a first jig conveying mechanism and a second jig conveying mechanism; the first jig conveying mechanism is movably arranged between the first buffer conveying mechanism and the transfer conveying mechanism and cooperates with the first buffer conveying mechanism and the transfer conveying mechanism; the second jig conveying mechanism is movably arranged between the transfer conveying mechanism and the second jig conveying mechanism and cooperates with the transfer conveying mechanism and the second buffer conveying mechanism; the first jig conveying mechanism and the second jig conveying mechanism are both provided with a vacuum channel docking with the lens barrel material tray.

[0019] It can be seen from the above scheme that the first buffer conveying mechanism, the transfer conveying mechanism and the second buffer conveying mechanism are used to temporarily store the lens barrel tray, thereby improving the loading efficiency, and realizing the rapid connection of the assembly of the second group of trays after the lens barrel assembly of one group of trays is completed. The first fixture conveying mechanism and the second fixture conveying mechanism are used to cooperate with the lens barrel tray to drive the tray to move, and at the same time provide negative pressure for the lens barrel tray, so that the lens barrel tray can continuously absorb the lens barrel product during the assembly process, improve the assembly stability, and avoid assembly deviation caused by material jumping due to mechanical vibration.

[0020] A preferred solution is that a second industrial camera cooperating with the lens high-speed rotating assembly mechanism is also arranged on the machine platform, and the second industrial camera is connected to the machine platform via a fine-tuning platform.

[0021] It can be seen from the above scheme that by setting the second industrial camera to take a picture of the lens picked up by the lens high-speed rotating assembly mechanism to locate it, it is detected whether the posture of the lens is correct and whether the structure is complete. By setting the fine-tuning platform to adjust the position of the second industrial camera, it is ensured that the lens is located in the center of the image obtained by the second industrial camera when picking up the material, thereby improving the detection accuracy.

[0022] A preferred solution is that the material tray transfer assembly also includes a linear electric cylinder and a rotating platform, the linear electric cylinder is fixed on the machine table, the rotating platform is arranged on the movable end of the linear electric cylinder, the movable end of the rotating platform is provided with a limit plate, the loading slot is arranged on the limit plate, the movable end of the linear electric cylinder is provided with a limit seat, and the bottom of the limit plate is provided with a limit bolt that cooperates with the limit seat.

[0023] It can be seen from the above scheme that the linear electric cylinder can drive the material tray to move along the length direction perpendicular to the two-axis moving assembly, and then cooperate with the two-axis moving assembly to remove the lenses distributed in the array on the material tray. The rotating platform can be set to fine-tune the posture of the limit plate, and then adapt to the loading error of the material tray, so that the angle adjustment of the lens when taking the material is more flexible and quick.

The top of the transmission ring 1082 is provided with several groups of transmission guide blocks 1085 and several linkage guide pins 1086. The bottom of the first coupling 1081 is correspondingly provided with a transmission limiting groove 1087 adapted to the transmission guide block 1085, and the bottom of the first coupling 1081 is also correspondingly provided with a limiting guide hole slidably matched with the linkage guide pin 1086. The lifting power mechanism 105 includes a small cylinder arranged on the mounting seat 101. The rotary joint 107 is connected to the external vacuum generator, and the hollow motor 102 is provided with a sensor. The rotary joint 107 is provided with a sensor sheet that cooperates with the sensor. The sensor sheet cooperates with the sensor to detect the rotation data of the vacuum suction nozzle 109, thereby obtaining the rotation data of the lens structure. The bottom of the first coupling 1081 is also provided with a avoidance hole coaxial with the guide column 1084. The guide column 1084 extends into the avoidance hole after passing through the transmission ring 1082. The aperture of the avoidance hole is larger than the diameter of the guide column 1084. The hollow motor 102 is fixed to the mounting seat 101 through a mounting panel, and the movable end of the lifting power mechanism 105 is connected to the sliding seat 104 through a linkage block passing through the mounting panel.

[0034] In this embodiment, the transmission guide block 1085 is an isosceles trapezoidal structure, and both sides of the transmission limit groove 1087 are provided with guiding inclined surfaces corresponding to and parallel to the inclined surfaces on both sides of the transmission guide block 1085 .

[0035] In this embodiment, a conduit joint 1061 is provided at the top of the hollow part of the hollow transmission rod 106, one end of the conduit joint 1061 is connected to the output end of the rotary joint 107, and the other end of the conduit joint 1061 is connected to an air conduit 1062, and the air conduit 1062 passes through the first coupling 1081, the transmission ring 1082 and the second coupling 1083 in sequence and then is connected to the vacuum suction nozzle 109.

[0036] In this embodiment, the vacuum suction nozzle 109 includes a vacuum tube 1091 and an air nozzle 1092. The vacuum tube 1091 is rotatably engaged on the sliding seat 104 through at least three sets of bearings 1093.

[0037] The working principle of the lens high-speed rotation assembly mechanism is as follows:

[0038] After the visual positioning of the lens product, the moving mechanism drives the lens high-speed rotating assembly mechanism to move to the top of the lens product to be assembled. After reaching the position, the lifting power mechanism 105 extends to drive the sliding seat 104 to descend so that the air nozzle 1092 contacts the lens product and absorbs the lens product through negative pressure. At this time, the transmission ring 1082 follows the second coupling 1083 to descend, and at the same time maintains linkage with the first coupling 1081 through the linkage guide pin 1086, and then keeps the air nozzle 1092 stationary by linkage with the first coupling 1081.

[0039] After the adsorption action is completed, the lifting power mechanism 105 retracts. During the retraction process, the transmission guide block 1085 on the transmission ring 1082 is guided and docked with the transmission limit groove 1087 to achieve automatic guide correction and ensure the overall rotation consistency. The moving mechanism drives the lens high-speed rotation assembly mechanism to move to the camera detection station, and the camera equipment takes a picture of the adsorbed lens to determine the posture of the lens. If rotation adjustment is required, the hollow motor 102 is rotated to drive the lens product on the air nozzle 1092 to rotate synchronously to adjust the posture. During the adjustment process, the first coupling 1081 and the transmission ring 1082 are tightly fitted under the action of the active end of the lifting power mechanism 105 to improve the stability of rotation.

[0041] In this embodiment, the camera detection module 5 includes two groups of parallel linear transport mechanisms 51 and two groups of detection camera assemblies 52. The two groups of detection camera assemblies 52 are respectively arranged on the movable ends of the two groups of linear transport mechanisms 51.

A connecting plate 55 is provided at the movable end of the linear transport mechanism 51 near the feeding module 6, and the material tray drag plate 7 is arranged on the connecting plate 55 through a lifting cylinder.

[0042] In this embodiment, the carrier transport module 3 includes a first buffer conveying mechanism 31, a transfer conveying mechanism 32, a second buffer conveying mechanism 33, a first jig conveying mechanism 34 and a second jig conveying mechanism 35.

[0045] Working principle of the present invention:

[0046] The carrier transport module 3 is connected to the carrier feeding mechanism and transports the lens barrel carrier. After the first jig conveying mechanism 34 drives the lens barrel carrier to be received from the first buffer conveying mechanism 31, the first jig conveying mechanism 34 moves to the lens assembly station between the first buffer conveying mechanism 31 and the transfer conveying mechanism 32. The camera detection module 5 takes pictures and positions the lens barrel carrier and the lens carrier on the feeding module 6 respectively and feeds back to the host computer. The host computer obtains the recognized image data to control the two-axis moving component 41, and then drives the lens high-speed rotating assembly mechanism 1 to move above the lens material tray. Two groups of lenses are taken at a time through two groups of the lens high-speed rotating assembly mechanisms 1. After taking the materials, the two groups of the lens high-speed rotating assembly mechanisms 1 move to the top of the second industrial camera 8. The second industrial camera 8 shoots the posture of the lens product from bottom to top. If there is a deviation in the posture, the lens high-speed rotating assembly mechanism 1 is controlled to adjust, thereby ensuring that the characteristics of the lens product match the installation characteristics of the lens barrel. After the adjustment is completed, the lens high-speed rotating assembly mechanism 1 moves to the top of the lens barrel carrier for lens installation.

[0047] During the initial feeding, the tray dragging plate 7 on the two-axis moving assembly 41 or the camera detection module 5 cooperates with the slot on the lens carrier to drag the lens carrier to the loading slot 65. After the lens high-speed rotating assembly mechanism 1 takes out a row of lens products, the linear electric cylinder 621 cooperates and moves forward to move the next row of lens products to the bottom of the lens high-speed rotating assembly mechanism 1. After a set of trays are taken out, the tray dragging plate 7 on the two-axis moving assembly 41 or the camera detection module 5 cooperates with the slot on the lens carrier to push the lens tray back into the magazine 63. The lifting assembly 61 drives the magazine 63 to lift and lower the full lens tray to a height matching the loading slot 65, and then the full lens tray is taken out by the tray dragging plate 7.
