Description

Technical Field

[0001] The invention relates to the technical field of LED lamp processing, and in particular to an LED lamp packaging process. Background Art

[0002] LED lights are popular because of their high efficiency, long life and environmental protection. LED lamps provide lighting by converting electrical energy into light energy, and have the advantages of high energy efficiency, low energy consumption and long life.

[0003] In the production process of LED lamps, packaging technology is required, which is a key link in modern lighting technology. Its performance and quality directly affect the application effect of the final product.

[0004] For example, a Chinese patent with publication number CN113275194A discloses a vehicle-mounted LED lamp packaging device, including a support base, which is used to support and stabilize the packaging panel. Through the coordinated use of the support base, the cross plate, the cam, the connecting rod, the connecting disk, the limit plate and the first rotating shaft, the support base is used to ensure continuous dispensing during packaging, thereby improving the work efficiency during dispensing, and automatically clamping and limiting during dispensing, without the need for manual support, thereby improving the stability during dispensing; through the coordinated use of the liquid storage tube, the push rod, the special-shaped roller and the third rotating shaft, quantitative dispensing is performed during dispensing packaging to avoid the dispensing amount affecting the packaging effect of the LED lamp and avoiding excessive dispensing amount causing waste of raw materials; through the coordinated use of the second rotating shaft, the pinion, the special-shaped disk and the round disk, the two steps of quantitative dispensing and continuous dispensing are linked, thereby increasing the linkage of the entire device and making the operation simpler.

[0005] However, the above LED lamp packaging equipment still has some shortcomings in actual use:

[0006] 1. First, in the above-mentioned prior art, quantitative glue dispensing is performed during glue dispensing packaging to avoid the glue dispensing amount affecting the packaging effect of the LED lamp and to avoid waste of raw materials caused by excessive glue dispensing amount; however, after a long period of operation, the entire equipment will age and wear, which will cause glue leakage during operation of the glue dispensing equipment, thereby affecting the stability of the glue output of the glue dispensing equipment, and ultimately causing problems when dispensing the LED lamp.

[0007] 2. Secondly, in the above-mentioned prior art, when limiting the position of the LED lamp, the prior art has poor limiting stability for the LED lamp, which can easily cause the LED lamp to shift.

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-Figure 13 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0046] See also Figure 1 , Figure 2 and Figure 3 As shown, the present application proposes an LED lamp, which includes a lampshade 1, wherein a horizontally distributed LED base plate 10 is provided inside the lampshade 1, a plurality of LED wicks 11 are arranged on the LED base plate 10 at equal intervals, and a conical groove 12 for installing the LED wicks 11 is provided on the LED base plate 10, a heat dissipation frame 13 for heat dissipation is provided on the outer side of the lampshade 1 close to the LED base plate 10, and an installation slot 14 for quick installation of the lampshade 1 is provided on the lampshade 1 and the heat dissipation frame 13, and an energized metal contact 15 is provided at the bottom of the lampshade 1, and the metal contact 15 is connected to the LED base plate 10 in the lampshade 1 through a wire.

[0047] It should be noted that the main function of the LED lamp in this application is to be used for lighting.

[0048] Firstly, a heat dissipation frame 13 is provided at the edge of the LED base plate 10 and the lampshade 1, which can effectively dissipate the heat emitted by the LED wick 11, thereby preventing the temperature of the LED wick 11 from being out of control when the LED wick 11 is in a constant light state.

[0049] Secondly, the LED lamp in the present application has the function of quick installation and disassembly. The installation slot 14 jointly opened on the lampshade 1, the heat dissipation frame 13 and the LED base plate 10 can be quickly connected to the external connection device. The installation slot 14 can be snapped into place through external known equipment to limit the entire LED lamp, so that the metal contact 15 at the tail of the LED lamp can be connected to the external power supply.

[0050] Then, six LED wicks 11 are arranged on the LED base plate 10 of the present application, and the arrangement of the six LED wicks 11 and the conical grooves 12 opened on the LED base plate 10 cooperate with each other; it should be noted that the angle of the conical groove 12 is a specific angle, and the outer wall of the conical groove 12 is sprayed with a silver coating to ensure that the light source of each LED wick 11 can diffuse outward after being lit.

[0051] The embodiment of the present application discloses an LED lamp packaging process, which illustrates that the LED lamp and its packaging process are mainly used in the production process of LED lamps, and in terms of technical effects: first, after working for a long time and the entire equipment is aged and worn, it will cause glue leakage in the glue dispensing equipment when it is not working, thereby affecting the stability of the glue output of the glue dispensing equipment, and ultimately causing problems when dispensing the LED lamp; secondly, when limiting the position of the LED lamp, the existing technology has poor limiting stability for the LED lamp, which can easily cause the LED lamp to shift.

[0052] Therefore, the present application proposes a packaging process for LED lamps. Embodiment 1:

[0053] During the processing of the above-mentioned LED lamp, a special LED lamp packaging equipment is required, as shown below.

[0054] Reference Figure 4As shown, it is a schematic diagram of the structure for packaging and processing LEDs, etc. in the present application; it includes a stationary packaging machine 2, a limit clamp 20 is provided at the upper end of the packaging machine 2 for limiting the lampshade 1, a glue dispensing nozzle 21 extending downward is provided on the packaging machine 2, and a movable frame 22 is also provided on the packaging machine 2. The glue dispensing nozzle 21 moves along the length and width directions of the packaging machine 2 through the movable frame 22. A protective component 23 for preventing glue leakage is also provided at the glue dispensing nozzle 21. The protective component 23 prevents the glue dispensing nozzle 21 from leaking glue, and the leaked glue is processed.

[0055] It should be noted that the movable frame 22 is an existing known structure, which can control the movement of the glue dispensing nozzle 21 in the XY axis direction, and can also control the up and down movement of the glue dispensing nozzle 21. The purpose is to facilitate the glue dispensing nozzle 21 to be accurately moved to the top of each LED lamp core 11 for accurate glue injection.

[0056] It should be noted that one side of the upper end of the packaging machine 2 is the placement area for the LED lamp to be processed, the other side of the upper end of the packaging machine 2 is the same placement area for the LED lamp after processing, and the middle part of the upper end of the packaging machine 2 is the processing area for the LED lamp, which is used for processing the LED lamp.

[0057] When processing the LED lamp, first, the lampshade 1 of the LED lamp is pressed against the packaging machine 2, and then the lampshade 1 is clamped by the limiting clamp 20 so that the LED wick 11 of the lampshade 1 is vertically limited upward on the packaging machine 2, and then the conical groove 12 where the LED wick 11 is located is injected with glue through the glue dispensing nozzle 21 to ensure that the glue can fill the entire conical groove 12 and form a water drop-shaped structure at the opening of the conical groove 12.

[0058] Reference Figure 5 As shown, that is, a schematic diagram of the structure for limiting and fixing the LED lamp in the present application; specifically, a limiting component 24 is also provided on the limiting clamp 20, and the limiting component 24 includes a limiting plate 240, a bidirectional threaded rod 241, a connecting rod 242 and a limiting motor 243. The limiting plate 240 is arranged on the packaging machine 2, and the bidirectional threaded rod 241 is rotatably arranged on the inner wall of the limiting plate 240 along the length direction through a bearing. The connecting rod 242 is symmetrically screwed on the bidirectional threaded rod 241 and slidably penetrated to one side of the limiting plate 240. A limiting groove for the connecting rod 242 to slide is provided on the limiting plate 240. The limiting motor 243 is installed on the packaging machine 2, and its output end is connected to the bidirectional threaded rod 241, and the connecting rod 242 is connected to the limiting clamp 20.

[0059] It should be noted that, in the initial state, the two limit clamps 20 are in a state of being away from each other, and the limit motor 243 is a servo motor, which can accurately control the start and stop of the bidirectional threaded rod 241.

[0060] When the lampshade 1 of the LED lamp is placed on the packaging machine 2 and is located between the two limit clamps 20, the limit motor 243 is started, and the limit motor 243 drives the bidirectional threaded rod 241 to rotate. At this time, the two connecting rods 242 screwed on the bidirectional threaded rod 241 control the limit clamps 20 to approach each other synchronously until the two limit clamps 20 synchronously contact the lampshade 1 of the LED lamp. At this time, the LED lamp is limited to ensure that the LED lamp can be in a vertical state, thereby preventing the LED lamp from shaking during the dispensing process.

[0061] In order to further improve the stability of the limiting clamping of the LED lamp shade 1, the present application further sets a limiting block 202 and a limiting column 201 according to the structural characteristics of the LED lamp shade 1, and the stability of the LED lamp shade 1 is reinforced by the limiting block 202 and the limiting column 201.

[0062] Reference Figure 6 As shown, specifically, the limiting clamp 20 is also integrally connected to a vertical plate 200, and a limiting column 201 is slidably penetrated along the thickness direction of the vertical plate 200, one end of the limiting column 201 is integrally connected to a limiting block 202 that rests against the mounting slot 14 of the lampshade 1, and the other end of the limiting column 201 is sleeved and connected with a resting tension spring 203.

[0063] During the specific implementation process, when the limit motor 243 controls the two limit clamps 20 to move toward the lampshade 1 placed in the middle, the limit column 201 and the limit block 202 are set on the limit clamp 20, and the limit block 202 is closer to the lampshade 1 than the two limit clamps 20, so the limit block 202 first contacts the lampshade 1 and can be inserted into the installation slot 14 opened on the lampshade 1. At this time, the limit block 202 abuts against the installation slot 14 of the lampshade 1 and fits therewith. As the limit motor 243 continues to rotate, the limit block 202 has abutted against the installation slot 14 of the lampshade 1 and cannot move further. At this time, the limit column 201 moves toward the end away from the lampshade 1 with the cooperation of the abutting tension spring 203 until the two limit clamps 20 clamp the lampshade 1 in the center.

[0064] At this time, the limit clamping plate clamps the lampshade 1 to prevent the lampshade 1 from shaking left and right; the limit block 202 rests against the installation slot 14 of the lampshade 1 to prevent the lampshade 1 from shaking back and forth; ultimately, the lampshade 1 can be prevented from shaking back and forth, left and right, and the stability of the lampshade 1 can be further improved.

[0065] When the LED lamp is clamped and limited, the glue dispensing nozzle 21 can be used to dispense glue to the LED lamp, so that the glue liquid enters the conical groove 12 on the LED bottom plate 10 in a quantitative manner, and then it is dried so that the glue liquid is quickly shaped and solidified.

[0066] At that time, with the long-term operation of the entire equipment, the dispensing nozzle 21 will cause aging, which will further cause the glue sprayed by the dispensing nozzle 21 to leak. The dispensing nozzle 21 cannot tightly close its glue outlet, which may easily lead to self-leakage of the glue during the movement of the entire dispensing nozzle 21.

[0067] Therefore, the present application proposes a protective component 23, which covers the glue outlet of the glue dispensing nozzle 21 to prevent the glue from falling on the LED lamp directly below it when the glue dispensing nozzle 21 leaks. The protective component 23 will only be opened when it is necessary to spray glue outward. It can not only prevent the LED lamp from being damaged when the glue dispensing nozzle 21 leaks, but also play a role in dustproof and heat preservation for the glue outlet of the glue dispensing nozzle 21, preventing external dust from entering the glue outlet of the glue dispensing nozzle 21. Therefore, when external dust enters the glue outlet of the glue dispensing nozzle 21, it will mix with the glue in the glue outlet, causing the glue outlet to be blocked and unable to discharge glue. The glue dispensing nozzle 21 is further covered and protected by the protective cover 230, which can play a role in heat preservation and prevent the glue from solidifying at the glue outlet and making it impossible to discharge glue.

[0068] Reference Figure 6 , Figure 7 and Figure 8 As shown, specifically, the protective component 23 includes two semicircular protective covers 230 that abut against each other to form a semicircular shape. The two protective covers 230 symmetrically cover the outside of the dispensing nozzle 21. The dispensing nozzle 21 is also provided with a heating cover 231 at one end close to the glue outlet. The heating cover 231 is provided with an arc-shaped slide groove 232. The inner walls of the two protective covers 230 are provided with an execution frame 233, and the protective covers 230 are controlled by the execution frame 233 to slide in the arc-shaped slide groove 232 of the heating cover 231.

[0069] It should be noted that in the initial state, the two protective covers 230 are against each other and cover the glue dispensing nozzle 21. At the same time, the heating cover 231 heats the glue dispensing nozzle 21 in real time to prevent the glue liquid in the glue dispensing nozzle 21 from solidifying.

[0070] When the glue dispensing nozzle 21 leaks glue, the glue will drip onto the inner wall of the protective cover 230 , thereby preventing the glue from dripping onto the LED lamp directly below the glue dispensing nozzle 21 .

[0071] Look again Figure 8 and Fig.11As shown, it is a schematic diagram of the structure of the linkage of the control protection cover 230 in this embodiment; a horizontal plate 210 is also provided on the glue dispensing nozzle 21, and linkage columns 211 are symmetrically penetrated on both sides of the length direction of the horizontal plate 210, and a linkage rope 212 is connected to the linkage column 211, and the linkage rope 212 extends downward and is connected to the execution frame 233. The glue dispensing nozzle 21 is located directly above the heating cover 231 and is also integrally connected to the fixed disk 213. The middle part of the linkage rope 212 slides through the fixed disk 213, and the part of the linkage rope 212 located between the fixed disk 213 and the execution frame 233 is sleeved with a linkage compression spring 214.

[0072] When the glue nozzle 21 moves downward, the horizontal plate 210 on the glue nozzle 21 moves downward synchronously, and the linkage column 211 set on the horizontal plate 210 also moves downward synchronously, and the bottom of the linkage column 211 is more protruding than the protective cover 230, so the linkage column 211 will first contact the LED bottom plate 10 of the LED lamp. As the glue nozzle 21 continues to move downward, the linkage column 211 will move upward due to the reaction force under the cooperation of the linkage compression spring 214. At this time, the linkage column 211 controls the execution frame 233 and the protective cover 230 to move upward through the linkage rope 212. At this time, the protective cover 230 moves upward along the arc-shaped slide groove 232 on the outer wall of the heating cover 231 with the cooperation of the execution frame 233 until the two protective covers 230 are opened to expose the glue dispensing nozzle 21. At this time, the glue dispensing nozzle 21 is just located above the conical groove 12 of the LED base plate 10 and close to the conical groove 12. Then a certain amount of glue is sprayed into the conical groove 12.

[0073] See also Fig. 9 and Fig.10 As shown, the bottom of the two protective covers 230 is provided with a leakage port 2300, and a leakage prevention door 2301 is hingedly installed in the leakage port 2300 through a torsion spring. If the dispensing nozzle 21 leaks and a certain amount of glue liquid is collected in the protective cover 230, the leakage prevention door 2301 is opened to guide the glue liquid. A collection ramp 36 is also provided at the leakage port 2300 of the protective cover 230 to guide the leaked glue liquid to prevent it from dripping onto the lampshade 1 and the LED base plate 10.

[0074] It should be noted that when the glue leaks into the interior of the protective cover 230, it will accumulate in the protective cover 230. If it is not cleaned in time, when the LED lamp is subsequently glued, a large amount of glue will splash onto the LED lamp at the moment the protective cover 230 is opened, causing damage to it.

[0075] Therefore, a leakage port 2300 is designed on the protective cover 230. When a certain amount of glue liquid is collected in the closed state of the protective cover 230, the weight of the glue liquid will be greater than the maximum bearing capacity of the anti-leakage door 2301 designed at the leakage port 2300 of the protective cover 230. Therefore, the anti-leakage door 2301 will open to discharge the glue liquid, so that the glue liquid enters the collection ramp 36 along the leakage port 2300, and the leaked glue liquid is treated in the same way. Embodiment 2:

[0076] Reference Fig.12 As shown, on the basis of Example 1, in order to further prevent the leakage of glue, the present application also proposes an early warning device 3. After the leakage of glue occurs, the early warning device 3 promptly issues an alarm to prevent the glue dispensing nozzle 21 from leaking glue for a long time, which will not only cause a waste of glue, but also the leakage of glue will gradually increase if the leaked glue is not controlled and repaired, and eventually cannot be handled.

[0077] Specifically, an early warning device 3 is also provided on the outside of the leak-proof door 2301. The early warning device 3 includes an early warning frame 30, an early warning probe 31, a first plate 32, a second plate 33, a reset spring 34 and an alarm 35. It should be noted that the alarm 35 is an existing known structure, which can generate sound and light alarms to improve the safety of the staff.

[0078] The early warning frame 30 is arranged on the outer wall of the protective cover 230, and the early warning frame 30 is arranged on one side of the leak-proof door 2301, the early warning probe 31 is slidably arranged in the early warning frame 30, and the No. 1 plate 32 is installed in the early warning frame 30 at one end away from the early warning probe 31, the No. 2 plate 33 is installed on the side of the early warning probe 31 close to the early warning frame 30, and the No. 2 plate 33 is slidably arranged in the early warning frame 30, the reset compression spring 34 is sleeved on the early warning probe 31, and the reset compression spring 34 is located between the No. 2 plate 33 and the inner wall of the early warning device 3, the alarm 35 is arranged on the outside of the early warning frame 30, and the alarm 35 is connected in series with the No. 1 plate 32 and the No. 2 plate 33 through a wire.

[0079] The alarm device 35 is connected in series with the first plate 32 and the second plate 33 through a wire, but in the initial state, the first plate 32 and the second plate 33 are not in contact and are in a disconnected state. Only when the first plate 32 and the second plate 33 are in contact can the alarm device 35 be powered on.

[0080] When the anti-leakage door 2301 mentioned above is opened, the anti-leakage door 2301 squeezes the early warning probe 31, so that the No. 2 piece 33 at the tail of the early warning probe 31 approaches the No. 1 piece 32 along the inner wall of the early warning frame 30, until the No. 1 piece 32 contacts the No. 2 piece 33, the alarm instrument 35 is powered on and starts to alarm, reminding the on-site staff to deal with the dispensing nozzle 21 in time to avoid the continuous expansion of the glue leakage of the dispensing nozzle 21 and ensure the stability of the quality of the entire dispensing nozzle 21.

[0081] See also Fig.13 As shown, in addition, the present invention also provides an LED lamp packaging process, comprising the following steps:

[0082] S1. Preparation: First, the pre-assembled LED lamps are uniformly processed and placed in the waiting area of ​​the packaging machine 2. This can achieve the same standard for the upper end of the packaging machine 2, avoid the LED lamps being scattered on the packaging machine 2, and avoid confusion between the processed LED lamps and the unfinished LED lamps.

[0083] S2. Product limiting: The LED lamp to be packaged is placed from the placement area to the processing area of ​​the packaging machine 2. At this time, the limiting motor 243 is started. The limiting motor 243 controls the two limiting clamps 20 to clamp the LED lamp in the center. At the same time, the limiting block 202 is inserted into the installation slot 14 opened on the lampshade 1 and the LED base plate 10, thereby ultimately ensuring the stability of the LED lamp.

[0084] S3. Product packaging: After the LED lamp is clamped in a limited position, the glue dispensing nozzle 21 is controlled by the mobile frame 22 to move to the position of the LED wick 11 on the LED lamp to be processed, so that it is located directly above the LED wick 11, and then the glue dispensing nozzle 21 dispenses glue into the conical groove 12 on the LED base plate 10 of the lampshade 1, so that the glue liquid enters into several LED lamps on the LED base plate 10 in turn.

[0085] S4. Glue dispensing protection: Before glue dispensing, the protective cover 230 in the protective component 23 always covers the outside of the glue dispensing nozzle 21 to protect the glue dispensing nozzle 21. When the glue dispensing nozzle 21 starts to spray glue, the two protective covers 230 open to facilitate the smooth falling of the glue. At the same time, if the glue dispensing nozzle 21 leaks, it can be protected by the protective cover 230 to prevent the glue dispensing nozzle 21 from being damaged and leaking, causing the glue to fall onto the packaging machine 2 and the LED lamp to be processed.

[0086] S5. Product curing: Then it is dried so that the glue adheres to the periphery of the LED lamp to protect the LED lamp. At the same time, the glue forms a lens effect on the LED lamp. When the product is dried, the processed LED lamp is placed in the same placement area. Finally, the above operation is repeated to package several LED lamps.
