Description

Technical Field

[0001] The present invention relates to the technical field of downlight assembly, and more particularly to an automatic assembly device for LED downlights. Background Art

[0002] In traditional automatic assembly lines for LED downlights, the assembly process has achieved a certain degree of automation; typically, a robotic arm performs the key operational task of adsorbing the LED light source and placing it in the location where the gel is applied so that the LED light source can adhere to the gel and prepare for subsequent installation inside the housing.

[0003] However, this process has many problems. On the one hand, there may be tiny defects such as transparent protrusions and depressions on the surface of the LED light source. In actual production, the quality inspection link may not be able to fully detect these minor defects. When the robot adsorbs the LED light source, if it happens to be adsorbed on these defects, the uneven contact of the adsorption surface will cause the LED light source to tilt. However, the tilt of the LED light source will bring more serious consequences.

[0004] When the LED light source is pressed down to contact the gel, the uneven pressure will cause uneven distribution of gel on the side of the LED light source that adheres to the gel. Specifically, there is too much gel in some areas, which may produce bubbles; while the gel in some areas is too thin or even missing. The thermal interface contact area in the area where the gel is too thin or missing is reduced, which causes the heat generated by the LED light source to be unable to be effectively conducted to the shell, causing the junction temperature of the LED light source to increase, and thus easily damaged. At the same time, the uneven distribution of gel will also reduce the effective bonding area between the LED light source and the shell. In an environment subjected to vibration or impact, the LED light source can easily detach from the shell, seriously affecting the quality and service life of the LED downlight. Therefore, we have designed an automatic assembly device for LED downlights. Summary of the Invention

[0005] The present invention provides an automatic assembly device for LED downlights, which solves the technical problems in related technologies that tiny defects that may not be discovered by quality inspection may exist on the surface of the LED light source. When a robot arm adsorbs on the defect, the LED light source will be tilted; when pressing down to contact the gel, uneven pressure causes uneven distribution of the gel, resulting in local excess, too thin or missing gel, which not only affects heat dissipation and makes the LED chip easily damaged, but also reduces the bonding area. When subjected to vibration and impact, the LED is easily separated from the shell, affecting the quality and life of the downlight.

[0016] The beneficial effects of the present invention are:

[0017] 1. The automatic assembly device for LED downlights described in the present invention cooperates with a universal ball joint and a limit frame. When the LED light source is not adsorbed stably, the dynamic adjustment function of the universal ball joint can be used to ensure that the LED light source is in stable contact with the two limit frames, thereby ensuring its balance relative to the coating mechanism. This effectively avoids assembly problems caused by the tilt of the LED light source, ensures that the LED light source is parallel to the contact surface of the gel, greatly improves the uniformity of gel coating and assembly accuracy, makes the installation of the LED light source and the housing more stable, and reduces the risk of product damage due to improper assembly.

[0018] 2. The automatic assembly device for LED downlights described in the present invention works in coordination with a force storage component and a drive component. During the downward pressing process of the LED light source, the drive component drives the force storage component to store kinetic energy. When the brush roller contacts the LED light source, the force storage component releases the kinetic energy to drive the brush roller to rotate, and evenly applies the gel to the LED light source. At the same time, the interaction between the first permanent magnet on the limit frame and the drive component enables the brush roller to move while rotating and applying, fully covering the bottom of the LED light source, ensuring uniform gel application, avoiding problems such as uneven gel distribution, local excessive thickness or excessive thinness, and improving the product's heat dissipation performance and bonding effect. The setting of the cleaning frame and the scraper can accurately control the amount of gel applied to prevent excessive gel overflow and affect product quality.

[0019] 3. In the automatic assembly device for LED downlights described in the present invention, when the suction cup becomes loose, the pressure rod automatically squeezes the LED light source under the action of the fifth spring to ensure that it is firmly bonded to the shell. This solves the problem of loose installation caused by the loose suction cup when the LED light source is close to and ready to be pressed onto the shell in traditional assembly, improves the assembly success rate of the product in various situations, and reduces rework and defective rates.

DETAILED DESCRIPTION

[0034] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0035] like Figures 1 to 13As shown, an automatic assembly device for LED downlights in an embodiment of the present invention includes an assembly line 1 provided with a robotic arm and a conveyor; a universal ball joint 701 is fixedly installed on the robotic arm, and a suction cup 702 is fixedly connected to the bottom of the joint; a stabilizing mechanism is fixedly installed inside the suction cup 702, and when the suction cup 702 installs the LED light source into the interior of the shell, the LED light source and the shell are stably bonded; the mounting tube 2 is fixedly installed on the conveyor, and a coating mechanism is fixedly installed inside the mounting tube 2; a balancing mechanism is arranged on the mounting tube 2, and a limiting frame 302 is arranged on the mounting tube 2, and when the LED light source is smoothed and pressed down by two limiting frames 302, the coating mechanism accumulates power, and after the LED light source contacts the coating mechanism, the gel is evenly coated on the LED light source.

[0036] It should be noted that there are multiple conveyors and robotic arms on the assembly line 1, and the functions of each conveyor and robotic arm are different. During the assembly of the LED downlight, the LED light source needs to be installed inside the shell. When the LED light source is installed inside the shell, it is necessary to first use a robotic arm equipped with a suction cup 702 to adsorb the LED light source, and send the adsorbed LED light source to the position for applying gel, so that the contact surface between the LED light source and the shell is coated with gel, and preliminary fixation is achieved with the help of gel. The gel also has a heat-conducting effect, which helps the LED light source dissipate heat during use.

[0037] When the LED light source is adsorbed by the suction cup 702 on the robotic arm and transferred to the gel application location, the LED light source continues to move downward under the action of the robotic arm until it contacts the limit frame 302. Since the LED light source is not necessarily adsorbed stably and there are two limit frames 302, if the LED light source is not stable, one will be high and the other low, and will first contact one limit frame 302. As it continues to move downward and squeeze, the universal ball joint 701 will cause the LED light source to deviate slightly, and thus stably contact the other limit frame 302. In this way, the LED light source will be parallel to the application mechanism, making it convenient for the application mechanism to subsequently apply gel to the LED light source.

[0038] When the LED light source is stable, it will continuously press down the limit frame 302 to move the limit frame 302 downward, thereby triggering the balancing mechanism to move it continuously downward until the LED light source contacts the coating mechanism. As the balancing mechanism moves downward, it will store power in the coating mechanism. When the LED light source contacts the coating mechanism, the previously stored power will be released again, thereby driving the coating mechanism to move and smoothly coat the gel on the LED light source. After the LED light source is coated with gel, the robotic arm will move the LED light source to the shell through the suction cup 702 and install the LED light source on the shell. If the suction cup 702 does not loosen during the installation process, the LED light source will be well installed. However, if it loosens, the LED light source can only rely on its own gravity to make the gel contact with the shell, which is not smooth enough. At this time, the stabilizing mechanism will unfold and squeeze the LED light source so that the LED light source and the shell are firmly bonded together.

[0039] like Figure 2 、 Figure 4 and Figure 5 As shown, the balancing mechanism includes an installation box 301 that is slidably connected to the limit frame 302; one end of the first spring 304 is connected to the limit frame 302, and the other end is connected to the installation box 301; the limit assembly is fixedly installed on the installation box 301; the extension block 305 is fixedly installed at the bottom of the limit frame 302; the slide rod 303 is fixedly installed at the bottom of the installation box 301; the third spring 310 is sleeved on the slide rod 303, and its two ends are respectively connected to the installation box 301 and the installation tube 2.

[0040] The limiting assembly includes a limiting tube 311 fixedly connected to the installation box 301; the limiting rod 309 is slidably installed inside the limiting tube 311 and is connected to the limiting tube 311 through a second spring 308; the pull plate 307 is slidably installed inside the installation box 301 and is connected to the limiting rod 309 through a pull rope 306.

[0041] It should be noted that after the suction cup 702 on the robotic arm absorbs the LED light source, it moves the LED light source to the top of the limit frame 302. Since the LED light source is not necessarily absorbed smoothly, the LED light source will first contact one limit frame 302. Due to the action of the universal ball joint 701, it can achieve self-dynamic adjustment due to the downward pressure, so that the LED light source contacts the two limit frames 302, making it balanced relative to the coating mechanism. Subsequently, as the LED light source continues to move downward, the LED light source will cause the limit frame 302 to move downward, the limit frame 302 will move the extension block 305 downward, the extension block 305 will move the pull plate 307 downward, the pull plate 307 pulls the pull rope 306, so that the limit rod 309 is away from the inner wall of the installation tube 2, so that the limit rod 309 will not be plugged into the slot on the inner wall of the installation tube 2, thereby canceling the limit of the installation box 301, so that the limit frame 302 can continue to drive the installation box 301 to move downward until the LED light source contacts the coating mechanism.

[0042] like Figure 2 and Figure 3 As shown, the smearing mechanism includes a storage box 402 that is slidably connected to the mounting cylinder 2; a slide plate 408 is fixedly mounted on the storage box 402, and a sleeve 407 is slidably connected thereto, and the sleeve 407 is connected to the storage box 402 through a sixth spring 417; both ends of the brush roller 409 are rotatably connected to the sleeve 407; a power storage component is fixedly mounted on the sleeve 407 and connected to the brush roller 409; a driving component is fixedly mounted on the mounting box 301, and cooperates with the power storage component to drive the brush roller 409 to smear the LED light source.

[0043] It should be noted that when the limit frame 302 continues to move downward, the limit frame 302 will drive the installation box 301 to move downward. The downward movement of the installation box 301 will drive the power storage component to store kinetic energy through the drive component. When the drive component moves down to the specified position, that is, after the brush roller 409 contacts the LED light source, the drive component will be disengaged from the power storage component, so that the power storage component will lose its limit and can release the stored kinetic energy, causing the brush roller 409 to rotate. In this way, the brush roller 409 can transport the gel in the installation tube 2 to the LED light source and apply the LED light source. Moreover, since the first permanent magnet is fixedly installed on the limit frame 302, the first permanent magnet will interact with the drive component to make the drive component and the power storage component move together. In this way, the brush roller 409 can not only rotate to apply the LED light source, but also move continuously to apply different positions of the LED light source.

[0044] like Figure 6 and Figure 7As shown, the power storage assembly includes a power storage box 404 fixedly connected to the slide sleeve 407; the drive shaft 413 is rotatably installed in the power storage box 404 and fixedly connected to the brush roller 409; the coil spring 414 is arranged inside the power storage box 404 and connected to the drive shaft 413; the mounting frame 405 is fixedly installed on the power storage box 404, and the rotating frame 410 is rotatably installed on it; the first gear 411 has a tooth groove running through the center and is fixedly connected to the rotating frame 410; the toggle piece 412 is located inside the tooth groove and is fixedly connected to the drive shaft 413.

[0045] It should be noted that as the installation box 301 moves downward, the driving component will continuously drive the first gear 411 to rotate the first gear 411. The rotation of the first gear 411 will drive the driving shaft 413 to rotate through the toggle piece 412, so that the driving shaft 413 will act on the coil spring 414 to store force. When the driving component is disengaged from the first gear 411, the coil spring 414 will lose its limit, thereby driving the driving shaft 413 to rotate, so that the driving shaft 413 drives the brush roller 409 to rotate, so that the brush roller 409 can apply the gel to the LED light source, and since the brush roller 409 is used for application, the gel at the application location can be effectively evenly distributed.

[0046] like Figure 3 and Figure 8 As shown, the driving assembly includes a connecting plate 401 fixedly connected to the mounting box 301, and a first sliding groove is provided on the connecting plate 401; a moving block 416 is slidably installed on the connecting plate 401, and a moving plate 415 is fixedly installed on it; a rack 406 is fixedly installed on the moving plate 415 and meshes with the first gear 411; and a first magnetic block 403 is fixedly installed on the moving plate 415.

[0047] It should be noted that the driving assembly moves downward, mainly driving the rack 406 to move downward, so that the rack 406 can drive the first gear 411 to move, thereby allowing the power storage assembly to store power, and the surface of the power storage box 404 is provided with a second slide groove with the same structure as the first slide groove, and a slider is provided inside the second slide groove, and the slider is fixedly connected to the rack 406, so that the rack 406 will be integrated with the power storage assembly and can only move up and down, and when the rack 406 moves down to a certain position, the teeth on the rack 406 are used up and cannot engage with the first gear 411, thereby releasing The force storage mechanism is provided so that the force storage mechanism can drive the brush roller 409 to operate, and a first permanent magnet is provided on the limit frame 302. The first permanent magnet and the first magnetic block 403 magnetically repel each other, thereby driving the movable plate 415 to move together with the force storage component, so that the rotating brush roller 409 can completely coat the bottom of the LED light source, which is convenient for the subsequent bonding of the LED light source to the shell. When the coating is completed, the limit frame 302 will return to its original position under the action of the third spring 310, and the brush roller 409 will return to its original position under the action of the sixth spring 417, which is convenient for continued use next time.

[0048] like Figure 9 As shown, a cleaning frame 501 is fixedly mounted on the sliding sleeve 407 , a common screw 502 is threadedly connected to the cleaning frame 501 , a scraper 503 is rotatably connected to the common screw 502 , and the scraper 503 is slidably connected to the cleaning frame 501 .

[0049] It should be noted that the thicker the gel is applied, the better. However, after the brush roller 409 delivers the gel, due to the characteristics of the gel, a lot of it may adhere to it and be directly applied to the LED light source. At this time, the ordinary screw 502 can be rotated to move the scraper 503. This can control the distance between the scraper 503 and the brush roller 409. When the brush roller 409 delivers the gel, the gel will be limited by the scraper 503 and can only deliver gel with a thickness of the gap, so that the amount of gel applied can be controlled to avoid excessive application of gel, which will cause too much gel to overflow when the subsequent LED light source is installed in the shell, affecting the LED light source.

[0050] like Figure 10 As shown, a lifting mechanism is provided inside the storage box 402, and the lifting mechanism includes a second gear 608 rotatably connected to the storage box 402, and a tooth groove is provided in the center of the second gear 608; a positioning plate 605 is fixedly installed inside the storage box 402, and a reciprocating screw 602 is rotatably installed on it, and a paddle 412 is fixedly installed at the bottom of the reciprocating screw 602; a pressure plate 601 is slidably connected to the storage box 402 and is threadedly connected to the reciprocating screw 602; a lifting assembly is provided below the pressure plate 601; the lifting assembly includes a push plate 606 slidably connected to the storage box 402, and the push plate 606 is connected to the storage box 402 through a fourth spring 607; a push frame 604 is fixedly installed on the push plate 606 and engages with the second gear 608.

[0051] It should be noted that when the slide bar 303 moves down to the bottom, the second permanent magnet embedded in the slide bar 303 will act on the third permanent magnet embedded in the push frame 604, causing the push frame 604 to move and drive the second gear 608. The second gear 608 drives the reciprocating screw 602 to rotate, and the rotation of the reciprocating screw 602 drives the pressure plate 601 to move upward. Therefore, each time the brush roller 409 applies the LED light source, the gel in the storage box 402 will move up a little, which is convenient for the brush roller 409 to continue to use. After use, the fourth spring 607 can also return it to its original position, which is convenient for continued use next time.

[0052] like Figure 13 As shown, the stabilizing mechanism includes a fixing tube 703 fixedly connected to the universal ball joint 701 ; a pressure rod 705 is slidably installed inside the fixing tube 703 and is connected to the fixing tube 703 through a fifth spring 704 .

[0053] It should be noted that after the gel is applied to the LED light source, the robotic arm will move the LED light source to the shell through the suction cup 702 and install the LED light source on the shell. If the suction cup 702 does not loosen during the installation process, the LED light source will be well installed. However, if it loosens, the LED light source can only rely on its own gravity to make the gel contact with the shell, which is not smooth enough. At this time, since there is no limit on the LED light source, the pressure rod 705 will be released, so that the pressure rod 705 squeezes the LED light source, so that the LED light source and the shell are firmly bonded together.

[0054] Working principle: The robotic arm on assembly line 1 uses a suction cup 702 fixed on a universal ball joint 701 to absorb the LED light source and transfer it to the gel application area. Since the LED light source may be unstable during absorption, when it contacts the limit frame 302, the universal ball joint 701 can achieve self-dynamic adjustment, so that the LED light source contacts both limit frames 302 and is balanced relative to the application mechanism.

[0055] The LED light source presses down the limit frame 302, and the limit frame 302 drives the extension block 305 to move downward. The extension block 305 moves the pull plate downward, and the pull plate pulls the limit rod 309 through the pull rope 306 to release the limit on the installation box 301. The installation box 301 moves downward together with the limit frame 302; during the downward movement of the installation box 301, the driving component drives the storage component to store kinetic energy.

[0056] The rack 406 in the driving assembly moves downward to drive the first gear 411 to rotate, and the first gear 411 drives the driving shaft 413 to rotate through the toggle piece 412, so that the coil spring 414 accumulates force; when the brush roller 409 contacts the LED light source, the driving assembly is disengaged from the force storage assembly, and the coil spring 414 releases kinetic energy to drive the driving shaft 413, driving the brush roller 409 to rotate, and applying the gel in the mounting tube 2 to the LED light source; at the same time, the first permanent magnet on the limit frame 302 and the first magnetic block 403 in the driving assembly magnetically repel each other, so that the force storage assembly moves together with the brush roller 409, ensuring that the bottom of the LED light source is fully coated with gel; in addition, the distance between the scraper 503 and the brush roller 409 can be adjusted by rotating the ordinary screw 502 on the cleaning frame 501 to control the amount of gel applied.

[0057] When the slide bar 303 moves down to the bottom, the second permanent magnet on the slide bar 303 acts on the third permanent magnet on the push frame 604, and the push frame 604 drives the second gear 608 to rotate, and the second gear 608 drives the reciprocating screw 602 to rotate, so that the pressure plate 601 moves upward, pushing the gel in the storage box 402 upward, making it easier for the brush roller 409 to continue to obtain gel; after use, under the action of the fourth spring 607, the relevant components return to their original positions.

[0058] The LED light source coated with gel is moved to the shell by the robotic arm through the suction cup 702 for installation; if the suction cup 702 is not loosened during the installation process, the LED light source is installed normally; if the suction cup 702 is loosened, the pressure rod 705 of the stabilizing mechanism will squeeze the LED light source under the action of the fifth spring 704, so that it is firmly bonded to the shell.

[0059] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
