Abstract
Description
Technical Field
[0001] This invention belongs to the field of lens light strip technology, and in particular relates to a dispensing machine for producing mini lens light strips. Background Technology
[0002] Miniature lens light strips are light strips made using micro-LEDs and microlens array (MLA) technology. They can be used in ceiling lights and other lighting applications, offering advantages such as high brightness, high contrast, low power consumption, and long lifespan. The light strip consists of multiple micro-LEDs and MLAs, each of which can be individually designed to achieve different optical effects. The lenses are mounted and fixed to the light strip with adhesive, ensuring even distribution and strong adhesion of the adhesive.
[0003] Currently, common lens mounting methods include the snap ring method, the set screw method, the pressure block method, and the adhesive application method. The snap ring method involves placing the lens in the mounting base and securing it with a snap ring pressing down on the lens edge. This method is simple and convenient, but may cause stress or damage to the lens. The set screw method involves placing the lens in the mounting base and securing it with one or more set screws from the side. This method avoids stress or damage to the lens, but requires precise adjustment of the set screw position and force. The pressure block method involves placing the lens in the mounting base and securing it with one or more pressure blocks from the top and bottom. This method allows for quick and flexible lens positioning and provides good stability, but may cause some stress or damage to the lens. The adhesive application method involves precisely injecting adhesive between the lens and the light strip to fix the lens. However, current production methods rely heavily on manual adhesive application, which is labor-intensive and cannot guarantee the quality and consistency of the light strip.
[0004] This paper proposes a dispensing machine that can control parameters such as dispensing volume, position, and speed to achieve circumferential dispensing around a lens, ensuring the quality and consistency of the LED strip. The dispensing machine can be adjusted according to different lens sizes and shapes to adapt to various LED strip designs. Summary of the Invention
[0005] The purpose of this invention is to provide a dispensing machine for the production of mini lens light strips, which solves the problem of poor dispensing quality and inability to dispense in a circular manner in existing production processes.
[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:
[0007] A dispensing machine for producing miniature lens LED strips includes a belt conveyor with a dispensing mounting platform. A lens mounting dispensing module is mounted on the platform and movably mounted on a three-axis movable mounting base. A material storage chute is located on the side of the dispensing mounting platform, and a material conveying slider is movably mounted on the side of the chute. A lens positioning groove is provided on the material conveying slider. The lens mounting dispensing module includes a lens mounting column, a first turntable is movably mounted on the column, and a lens transport positioning groove is provided at the lower end of the column. A dispensing device is mounted on the first turntable, and a dispensing nozzle is located below the dispensing device. The lens transport positioning groove is connected to a suction pipe.
[0008] Furthermore, the side of the dispensing mounting table is provided with a feeder, and the side of the feeder is provided with a discharge chute, which is connected to the storage chute.
[0009] Furthermore, the feeder has two unloading chute on its side, and the dispensing mounting platform has two storage chutes corresponding to the unloading chute and a lens mounting dispensing module.
[0010] Furthermore, the light strip body to be processed has light strip positioning grooves on both sides, a positioning block is provided above the belt conveyor, and a positioning boss is provided below the positioning block. The positioning boss is movably installed in the light strip positioning groove.
[0011] Furthermore, the positioning boss is provided with a roller mounting groove, and multiple evenly distributed positioning rollers are movably mounted in the roller mounting groove.
[0012] Furthermore, a second gear is mounted on the first slip ring, a first motor is mounted on the first turntable, and a first gear is mounted on the main shaft of the first motor. The first gear meshes with the first slip ring.
[0013] Furthermore, the dispensing device includes a feeding block with a feeding mounting hole. A gear pump mounting groove is provided at the lower end of the feeding mounting hole. A first mounting shaft and a second mounting shaft are provided on the gear pump mounting groove. Pump gears that cooperate with each other are mounted on the first mounting shaft and the second mounting shaft. A dispensing nozzle is connected below the feeding mounting hole.
[0014] Furthermore, a clearance arc groove is provided below the feed block, and a connecting ball head is provided at the upper end of the dispensing nozzle. The connecting ball head has multiple through holes and is movably installed in the spherical mounting groove at the upper end of the feed block. The spherical mounting groove is connected to the gear pump mounting groove.
[0015] Furthermore, one end of the second mounting shaft protrudes from the housing and is fitted with a fourth gear. A gear mounting groove is provided on the first slip ring, and a third gear is installed in the gear mounting groove. The third gear and the fourth gear mesh with each other.
[0016] A mini lens light strip includes a light strip body with multiple circumferentially distributed lens mounting slots on the light strip body. A light-emitting element is installed at the center of the lens mounting slot, and a light strip lens is installed on the lens mounting slot. The light strip is produced by a dispensing machine for producing mini lens light strips as described in any one of claims. Beneficial effects
[0017] The negative pressure of the suction pipe draws the LED strip lens onto the lens transport positioning groove. After the lens is drawn, the lens installation dispensing module moves onto the LED strip to be installed and then moves downward so that the lower end face of the LED strip lens contacts the LED strip. The first turntable moves downward so that the lower end face of the dispensing nozzle approaches the lower end face of the LED strip lens. The hydraulic pump works by squeezing the adhesive through the dispensing nozzle onto the contact surface between the LED strip lens and the LED strip. At the same time as the adhesive is squeezed out, the first turntable rotates so that the entire ring surface of the LED strip lens is evenly coated with adhesive.
[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.
[0030] Example 1, please refer to Figures 2-3 As shown, a mini lens light strip includes a light strip body 101. The light strip body 101 has multiple circumferentially distributed lens mounting slots 104. A light-emitting element 103 is installed at the center of the lens mounting slot 104, and a light strip lens 8 is installed on the lens mounting slot 104. The light strip lens 8 is fixedly installed on the light-emitting element 103 with glue. With this design, different light strip lenses 8 can be rotated for installation according to different needs, improving production compatibility.
[0031] Furthermore, the light strip lens 8 includes a cylindrical section 81 and an arc-shaped section 82. The cylindrical section 81 is installed in the lens mounting groove 104, which can ensure the accuracy of the installation position of the light strip lens 8.
[0032] Example 2, please refer to Figures 1-8 As shown,
[0033] This invention relates to a dispensing machine for producing mini lens LED strips, comprising a belt conveyor 3, a dispensing mounting platform 2 on the belt conveyor 3, a lens mounting dispensing module 5 on the dispensing mounting platform 2, and the lens mounting dispensing module 5 being movably mounted on a coordinate measuring machine (CMM) mounting base; a material storage chute 21 is provided on the side of the dispensing mounting platform 21, and a material conveying slider 22 is movably mounted on the side of the material storage chute 21, with a lens positioning groove 23 formed on the material conveying slider 22; the lens mounting dispensing module 5 includes a lens mounting column 51, a first turntable 54 is movably mounted on the lens mounting column 51, a lens transport positioning groove 52 is formed at the lower end of the lens mounting column 51, a dispensing device 6 is mounted on the first turntable 54, a dispensing nozzle 61 is provided below the dispensing device 6, and the lens transport positioning groove 52 is connected to an air suction pipe;
[0034] With this design, during production, the LED strip lens 8 to be installed is placed in the storage chute 21. The foremost LED strip lens 8 in the storage chute 21 moves into the lens positioning groove 23. The conveying slider 22 moves forward, moving the LED strip lens 8 in the lens positioning groove 23 to the set position. In this way, the position of the LED strip lens 8 can be ensured by the repositioning of the conveying slider 22 and the lens positioning groove 23. After the conveying slider 22 moves to the rear, the lens mounting dispensing module 5 moves above the lens positioning groove 23. The lens mounting dispensing module 5 moves downward to the middle of the lens transport positioning groove 52. The lens 8 is aligned with the center of the light strip lens 8. The negative pressure of the suction pipe draws the light strip lens 8 onto the lens transport positioning groove 52. After drawing, the lens mounting dispensing module 5 moves to the light strip to be installed and then moves downward so that the lower end face of the light strip lens 8 contacts the light strip. The first turntable 54 moves downward so that the lower end face of the dispensing nozzle 61 is close to the lower end face of the light strip lens 8. The hydraulic pump works and the glue is squeezed out through the dispensing nozzle 61 onto the contact surface between the light strip lens 8 and the light strip. At the same time as the glue is squeezed out, the first turntable 54 rotates so that the entire ring surface of the light strip lens 8 is evenly coated with glue.
[0035] Furthermore, one end of the material storage chute 21 is provided with a slider mounting groove, and the material conveying slider 22 is movably installed in the slider mounting groove. The material conveying slider 22 is driven by a cylinder, a lead screw, or a rack. Furthermore, the first turntable 54 is movably installed on the first slip ring 53. The first slip ring 53 is driven to move vertically by a cylinder or a lead screw. The first turntable 54 can be movably installed on the first slip ring 53 via a T-shaped annular mounting boss, thus ensuring free rotation while maintaining vertical stability. The dispensing device 6 can be connected to a glue hose, or the glue can be placed on the dispensing device 6.
[0036] In some disclosures, the side of the dispensing mounting table 2 is provided with a feeder 1, and the side of the feeder 1 is provided with a discharge chute 11. The discharge chute 11 is connected to the storage chute 21. With this design, automatic loading and unloading can be completed to improve production efficiency.
[0037] In some disclosures, the feeder 1 has two unloading chutes 11 on its side, and the dispensing mounting platform 2 has two storage chutes 21 corresponding to the unloading chutes 11 and a lens mounting dispensing module 5, which can realize multi-station production and improve production efficiency.
[0038] In some disclosures, the light strip body 101 of the light strip to be processed 10 has light strip positioning grooves 102 on both sides, a positioning block 31 is provided above the belt conveyor 3, and a positioning boss 32 is provided below the positioning block 31. The positioning boss 32 is movably installed in the light strip positioning groove 102. With this design, the light strip to be processed 10 can be positioned by the cooperation of the positioning boss 32 and the light strip positioning groove 102, ensuring its stability and accurate position during transportation.
[0039] In some disclosures, the positioning boss 32 is provided with a roller mounting groove 33, and multiple evenly distributed positioning rollers 34 are movably installed in the roller mounting groove 33. With this design, when the light strip 10 to be processed is transported on the belt conveyor 3, the positioning rollers 34 roll in this way, which can reduce the frictional resistance of the light strip 10 to be processed and ensure the order of its transportation.
[0040] Furthermore, the positioning block 31 is driven to move up and down by a cylinder or a lead screw, and the driving device is fixedly installed on the bracket of the belt conveyor 3.
[0041] Furthermore, the structure of the coordinate measuring machine mounting bracket mounting device 4 is as follows:
[0042] A horizontal guide rail is fixed on the dispensing mounting table 2, and a slider that can move along the horizontal axis is mounted on the horizontal guide rail.
[0043] A vertical guide rail is fixed on the slider, and a motion bracket that can move along the vertical axis is mounted on the vertical guide rail.
[0044] A coordinate measuring machine mount is fixed to a vertical guide rail on a motion support, and the vertical guide rail can move along the vertical axis.
[0045] In this way, by controlling the movement of these three parts, a three-axis motion mounting base can be achieved. Lead screws or cylinders are used to drive the movement of the guide rails and rotary table, as they provide precise and stable positioning. Sensors and controllers can also be used to monitor and adjust the speed and position of the movement.
[0046] In some disclosures, a second gear 57 is mounted on the first slip ring 53, a first motor 55 is mounted on the first turntable 54, and a first gear 56 is mounted on the main shaft of the first motor 55. The first gear 56 meshes with the first slip ring 53. With this design, when the first turntable 54 needs to rotate, the rotation of the first gear 56 driven by the first motor 55, in conjunction with the first slip ring 53, can complete the rotation of the first turntable 54, thus ensuring the compactness of the structure.
[0047] Furthermore, the first motor 55 and the dispensing device 6 are arranged diagonally to ensure the dynamic balance of the rotation of the first turntable 54.
[0048] In some disclosures, the dispensing device 6 includes a feed block 7 with a feed mounting hole 71. A gear pump mounting groove 73 is located at the lower end of the feed mounting hole 71. A first mounting shaft 74 and a second mounting shaft 75 are mounted on the gear pump mounting groove 73. Mutually engaging pump gears are mounted on the first mounting shaft 74 and the second mounting shaft 75. A dispensing nozzle 61 is connected below the feed mounting hole 71. With this design, the two pump gears mounted on the first mounting shaft 74 and the second mounting shaft 75 form a gear pump, which drives the adhesive in the feed mounting hole 71 forward through its rotation. This utilizes the characteristics of the gear pump to ensure a fixed amount of adhesive is dispensed.
[0049] Furthermore, a glue material tank can be installed on the feed mounting hole 71, or it can be connected to a glue bucket via a pipe. The housing of the feed block 7 is composed of two outer shell components 72, making it easy to install and disassemble.
[0050] In some disclosures, a clearance arc groove 62 is provided below the feed block 7, and a connecting ball head 63 is provided at the upper end of the dispensing nozzle 61. The connecting ball head 63 has multiple through holes and is movably installed in the spherical mounting groove at the upper end of the feed block 7. The spherical mounting groove is interconnected with the gear pump mounting groove 73. Through this design, the clearance of the clearance arc groove 62 and the movable installation of the connecting ball head 63 allow the dispensing nozzle 61 to be adjusted at multiple angles, thus meeting different production needs. Glue flows from the gear pump mounting groove 73 into the dispensing nozzle 61 through the through holes on the connecting ball head 63.
[0051] In some disclosures, one end of the second mounting shaft 75 protrudes from the housing and is fitted with a fourth gear 76. A gear mounting groove 58 is formed on the first slip ring 53, and a third gear 59 is installed within the groove. The third gear 59 meshes with the fourth gear 76. With this design, as the first turntable 54 rotates, the gear pump is driven by the cooperation of the fourth gear 76 and the third gear 59. This ensures a high degree of matching between the glue dispensing nozzle 61 and the rotational speed of the first turntable 54, preventing missed dispensing or excessive dispensing. Furthermore, after each dispensing cycle, as the first slip ring 53 moves upward, the first turntable 54 rotates backward a short distance, thus drawing up any remaining glue from the lower end of the dispensing nozzle 61 and preventing dripping.
[0052] Furthermore, the fourth gear 76 can be mounted on the drive shaft, which is movably mounted on the feed block 7. The drive shaft drives the rotation of the second mounting shaft 75 and / or the first mounting shaft 74 through a gear system or transmission belt, thus ensuring that the axis of the drive shaft intersects perpendicularly with the axis of the third gear 59.
[0053] Working principle:
[0054] During production, the LED strip lens 8 to be installed is placed in the storage chute 21. The foremost LED strip lens 8 in the storage chute 21 moves into the lens positioning groove 23. The conveying slider 22 moves forward to move the LED strip lens 8 in the lens positioning groove 23 to the set position. In this way, the position of the LED strip lens 8 can be ensured by the repositioning of the conveying slider 22 and the lens positioning groove 23. After the conveying slider 22 moves to the rear, the lens mounting dispensing module 5 moves above the lens positioning groove 23. The lens mounting dispensing module 5 moves downward and the center of the lens transport positioning groove 52 aligns with... The center of the LED strip lens 8 is aligned, and the negative pressure of the suction pipe draws the LED strip lens 8 onto the lens transport positioning groove 52. After drawing, the lens mounting dispensing module 5 moves to the LED strip to be installed and moves downward so that the lower end face of the LED strip lens 8 contacts the LED strip. The first turntable 54 moves downward so that the lower end face of the dispensing nozzle 61 is close to the lower end face of the LED strip lens 8. The hydraulic pump works and the glue is squeezed out through the dispensing nozzle 61 onto the contact surface between the LED strip lens 8 and the LED strip. At the same time as the glue is squeezed out, the first turntable 54 rotates so that the entire ring surface of the LED strip lens 8 is evenly coated with glue.
