[0038] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0039] During the production of the light strip assembly, the light strip needs to be placed inside the PC plastic fixing strip, and then the two are wrapped and covered with light-shielding tape, leaving only one side exposed to control the lighting effect of the ambient light, thus forming the light strip assembly.

[0040] In the traditional process of encapsulating LED strip components, manual operation is inefficient. The speed of manual edge wrapping and adhesive application is slow, the quality is unstable, and the deviation of the tape application position is large. It is difficult to ensure that the application position is exactly the same every time, with an error of ±1mm or more. This will affect the final lighting effect of the ambient light. In addition, the tightness of manual operation is uneven. If it is too tight, it may cause the tape to deform, and if it is too loose, it will easily fall off.

[0041] To solve the above problems, please refer to... Figures 1-6 As shown in the preferred embodiment of this application, a light strip coating equipment 10 is used to automatically coat light strips and fixing strips to form light strip assemblies 20, so as to ensure the consistency and continuity of light strip coating, thereby improving the efficiency and quality of light strip coating.

[0042] In this embodiment, the LED strip coating equipment 10 includes a workbench 1, an LED strip conveying base 2, a coating assembly 3, and a power transmission assembly 4. The workbench 1 has a first guide groove 11 for the LED strip assembly 20 to pass through and a conveying groove 12 extending along a first direction from the first guide groove 11. The LED strip conveying base includes a base 21 mounted on the workbench 1. The base 21 has a second guide groove 211 that at least partially overlaps with the first guide groove 11 in the height direction. The first guide groove 11 is used to place a fixing strip, and the second guide groove 211 is used to place the LED strip. The coating assembly 3 is disposed on one side of the LED strip conveying base 2 along the first direction and has a first position and a second position. When in the first position, the coating is performed. The component 3 and the conveying trough 12 do not overlap in the height direction. When in the second position, the coating component 3 and the conveying trough 12 overlap at least partially in the height direction. The coating component 3 is configured to connect the light strip and the fixing strip from the side simultaneously to form the light strip assembly 20 when in the second position. The power conveying component 4 is disposed on one side of the coating component 3 along the first direction and includes a drive wheel 41 and a driven wheel 42 located on both sides of the light strip assembly 20 in the conveying trough 12. The driven wheel 42 can move relative to the drive wheel 41 under the action of external force to clamp or release the light strip assembly 20.

[0043] Understandably, by setting up a workbench 1, a light strip conveying base 2, a wrapping assembly 3, and a power transmission assembly 4, the automated wrapping process of the light strip assembly 20 is achieved. The first guide groove 11 and the conveying groove 12 on the workbench 1 provide a stable path for the conveying of the light strip assembly 20; the second guide groove 211 of the light strip conveying base 2 can accurately place the light strip so that it cooperates with the fixing strip; the movable design of the wrapping assembly 3 (first position and second position) makes the wrapping operation more flexible and can complete the connection of the light-shielding tape at the appropriate position; the driving wheel 41 and the driven wheel 42 of the power transmission assembly 4 can clamp or release the light strip assembly 20, ensuring the stability and reliability of the conveying process, thereby improving the efficiency and quality of the light strip wrapping and reducing the error and labor intensity of manual operation.

[0044] Furthermore, the overmolding assembly 3 includes a mounting frame 31, a tape reel 32 mounted on the mounting frame 31, a take-up reel 33, and a pressing roller assembly 34. The tape reel 32 is used to wind the light-shielding tape, and the take-up reel 33 is used to wind the release paper of the light-shielding tape. The light-shielding tape is sequentially wound around the pressing roller assembly 34 from the tape reel 32, so that the pressing roller assembly 34 can automatically press the light-shielding tape provided by the tape reel 32 onto the light strip and the fixing strip to form the light strip assembly 20.

[0045] Furthermore, the overcoating assembly 3 includes a first drive unit connected to the tape reel 32 and a synchronous belt connecting the tape reel 32 and the take-up reel 33. The first drive unit can drive the tape reel 32 to rotate and drive the take-up reel 33 to rotate, so as to realize the synchronous rotation of the tape reel 32 and the take-up reel 33, ensuring that the light-shielding tape and release paper can be transported and recycled synchronously, thereby ensuring the stability of the tension of the light-shielding tape during the transport process.

[0046] In this embodiment, the pressure roller assembly 34 includes a guide wheel 341 mounted on the mounting frame 31 and a guide positioning wheel 342 located near the conveying groove 12. The light-shielding tape is wrapped around the guide wheel 341 and the guide positioning wheel 342 in sequence and then connected to the side of the light strip and the fixing strip.

[0047] Understandably, by setting the guide wheel 341, the light-shielding tape can be guided so that the light-shielding tape can smoothly enter the guide positioning wheel 342. The guide positioning wheel 342 is set close to the conveying groove 12, which can more accurately guide the light-shielding tape to the side of the light strip and the fixing strip, ensuring that the connection position between the tape and the light strip assembly 20 is accurate.

[0048] Furthermore, a positioning groove 3421 is provided on the guide positioning wheel 342. The positioning groove 3421 is configured such that when the light strip and the fixing strip pass through the positioning groove 3421, the sides of the light strip and the fixing strip are connected by the light-shielding tape in the positioning groove 3421. This precisely guides the light-shielding tape to the sides of the light strip and the fixing strip and connects them, achieving pre-positioning of the light strip and the fixing strip, i.e., fixing their relative positions. This prevents the relative positional shift of the light strip and the fixing strip in subsequent processes, which could lead to coating failure or misalignment. It should be noted that in this embodiment, the width of the positioning groove 3421 is equal to or slightly greater than the thickness of the light strip assembly 20, further ensuring that the positioning groove 3421 can connect the middle part of the light-shielding tape to the sides of the light strip and the fixing strip.

[0049] It should be noted that in this embodiment, a transition wheel 343 is also provided between the tape reel 32 and the receiving reel 33. After the tape reel 32 is fed around the transition wheel 343, the release paper is collected by the receiving reel 33. The light-shielding tape passes through the guide wheel 341 and the guide positioning wheel 342 in sequence to achieve subsequent fixation of the fixing strip and the light strip.

[0050] The pressure roller assembly 34 also includes a guide pre-pressure roller 344 disposed on one side of the guide positioning roller 342 along the first direction. The guide pre-pressure roller 344 is provided with a pre-pressure groove 3441, which has a groove body 3442 and extended arc surfaces 3443 located on both sides of the groove body 3442. The purpose of this arrangement is that the groove body 3442 and the extended arc surfaces 3443 of the pre-pressure groove 3441 are designed to pre-pressure the light-shielding tape initially, so that it has a certain degree of adhesion before entering the subsequent coating process, thereby better connecting with the light strip and fixing strip, which helps to improve the tightness and firmness of the coating, and at the same time reduces the connection problems caused by excessive or insufficient tape tension, further improving the coating quality.

[0051] Furthermore, the pressure roller assembly 34 also includes a rolling roller 345 disposed on one side of the guide pre-pressure roller 344 along the first direction. The rolling roller 345 is used to roll the LED strip assembly 20 within the conveying groove 12. Specifically, the rolling roller 345 is provided with a rolling groove 3451. When the adhesive-coated assembly 3 is in the second position, the area of ​​the orthographic projection of the rolling groove 3451 onto the LED strip assembly 20 is larger than the area of ​​the orthographic projection of the pre-pressure groove 3441 onto the LED strip assembly 20. That is, the area of ​​the LED strip assembly 20 within the conveying groove 12 located in the rolling groove 3451 is larger than the area within the pre-pressure groove 3441, ensuring that most of the light-shielding tape on the side closest to the LED strip assembly 20 can be rolled.

[0052] Furthermore, the pressing roller assembly 34 also includes a pressing roller 346 disposed on one side of the pressing roller 345 along the first direction. The pressing roller 346 includes a first wheel body 3461 and a second wheel body 3462 located on both sides of the conveying groove 12. The first wheel body 3461 and the second wheel body 3462 are respectively used to press the upper and lower surfaces of the light strip assembly 20.

[0053] Understandably, the first wheel 3461 and the second wheel 3462 are located on both sides of the conveying groove 12, respectively, and can press the light strip assembly 20 from both above and below to ensure that the light-shielding tape is tightly adhered to the entire surface of the light strip assembly 20. This all-round pressing operation can effectively improve the firmness and consistency of the coating, making the light strip assembly 20 more stable and reliable in subsequent use, and reducing the risk of failure due to insecure coating.

[0054] Understandably, in this application, the light-shielding tape near the side of the LED strip assembly 20 is first pressed using the roller groove 3451, and then the entire light-shielding tape is pressed using the pressure roller 346. The advantage of this step-by-step pressing method is that the roller groove 3451 can initially fix the position of the tape, effectively reducing the possibility of the tape shifting or wrinkling in subsequent operations. Then, the pressure roller 346 fully applies the entire light-shielding tape, which can further compact the tape and ensure that it is tightly adhered to the surface of the LED strip and the fixing strip, thereby improving the adhesion. Furthermore, when the roller groove 3451 first presses a portion of the light-shielding tape, it can initially eliminate the air between the tape and the LED strip assembly 20, reducing the formation of air bubbles. The full application by the pressure roller 346 can further compact the tape, ensuring that there are no gaps between the tape and the LED strip assembly 20, thereby improving the sealing and waterproof and dustproof performance of the tape.

[0055] In this embodiment, the coating equipment 10 also includes a detection element 5 mounted on the mounting frame 31. The detection element 5 is used to detect the LED strip assembly 20 in the conveying trough 12. Specifically, the detection element 5 is located between the guide positioning wheel 342 and the guide preload wheel 344, and is used to detect whether the LED strip assembly 20 is present in the conveying trough 12. When the detection element 5 detects that there is no LED strip assembly 20 in the conveying trough 12, it will send a signal to the control component, and the control component will control the power transmission component 4 to stop working. In this embodiment, the detection element 5 is a fiber optic distance sensor. In other embodiments, the specific type of the detection element 5 is not limited, and it depends on the actual needs.

[0056] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
