[0002] At present, in the LED identification module industry, the LED module needs to be pasted with back adhesive. However, since the LED module is in the form of a lamp string, the LED module includes a plurality of sequentially arranged lamp string beads and LED lamp string connecting lines. Therefore, the product needs to be pasted with back adhesive. However, after pasting, it is convenient to tear open the single lamp string bead. At present, the form is to directly paste and then manually tear open the single lamp string bead. Alternatively, the back adhesive raw material is required to be cut by a dashed line, and then the back adhesive is pasted at the position corresponding to the dashed line by manual operation. Both of the two forms consume a large amount of labor for operation.

[0019] As shown in Figures 1 to 10, this invention provides an automatic adhesive application device for LED modules, comprising a frame 10, a feeding mechanism 20 for feeding LED modules, a feeding mechanism 30 for feeding adhesive, an adhesive application mechanism 40 for applying adhesive to LED modules, and a cutting mechanism 50 for cutting the adhesive applied to the LED modules. The feeding mechanism 20, the adhesive application mechanism 40, and the cutting mechanism 50 are sequentially arranged on the frame 10; wherein: The feeding mechanism 30 corresponds to the pasting mechanism 40; the loading mechanism 20 includes a loading and correction component 21 for correcting the position of the LED module and a flipping component 22 for detecting the front and back of the LED module and flipping it so that the front is facing up. The LED module passes through the loading and correction component 21 and the flipping component 22 in sequence.

[0020] By employing a feeding and straightening assembly 21 and a flipping assembly 22, the front and back sides of the LED module are identified and flipped. The feeding mechanism 20, the feeding mechanism 30, the pasting mechanism 40, and the cutting mechanism 50 automate the feeding, pasting, and cutting of the LED module and adhesive, improving production efficiency and product quality. The automated feeding, pasting, and cutting of the LED module and adhesive reduces manual intervention and increases production efficiency. The feeding and straightening assembly 21 ensures accurate LED module positioning, the flipping assembly 22 identifies and flips the front and back sides, and the pasting mechanism 40 and the cutting mechanism 50 operate precisely, ensuring the quality of the adhesive application and the neatness of the cutting.

[0021] The feeding and straightening assembly 21 includes a guide groove 211 and a guide block 212. The guide block 212 is inclined and disposed on the front side of the guide groove 211. A straightening space 213 for guiding the LED module is formed between the guide groove 211 and the guide block 212.

[0022] The front side of the guiding space 213 is a downward-sloping "V"-shaped opening, and the rear side of the guiding space 213 is a square opening that matches the shape of the LED module. The guiding space 213 gradually narrows along the moving direction of the LED module.

[0023] The flipping assembly 22 includes a flipping drive device 221, a rotating material tube 222, and an infrared sensor. The rotating material tube 222 is installed at the output end of the flipping drive device 221. The LED module passes through the rotating material tube 222, and the infrared sensor faces the LED module. The flipping drive device 221 includes a flipping drive motor, a drive wheel, a driven wheel, and a transmission belt. The drive wheel is sleeved on the output end of the flipping drive motor, the transmission belt is sleeved on the drive wheel and the driven wheel, and the driven wheel is sleeved on the outside of the rotating material tube 222. The flipping drive device 221 drives the rotating material tube 222 to rotate, flipping the LED module.

[0024] The feeding mechanism 20 integrates the feeding correction component 21 and the flipping component 22, which can perform position correction and front / back identification and flipping of the LED module. This ensures that the LED module is accurately positioned and faces upwards before entering the subsequent pasting and cutting processes, laying the foundation for high-quality adhesive application and avoiding problems such as adhesive application failure and product defects caused by module position deviation or incorrect front / back orientation, thereby improving production efficiency and product qualification rate.

[0025] The guiding space 213 design ensures that the LED module, regardless of its orientation when entering the guiding space 213, is gradually corrected to the correct position during movement. The "V"-shaped opening guides modules entering at different angles to smoothly enter the guiding space 213, and the gradually narrowing structure allows for precise position adjustment of the module, ensuring it enters subsequent processes in an accurate posture, effectively improving the accuracy and stability of material feeding.

[0026] The infrared sensor of the flipping assembly 22 can accurately detect the front and back of the LED module. When the front of the module (the LED bead or lampshade side) is detected, the rotating feed tube 222 does not move; when the back side is detected, the flipping drive device 221 drives the rotating feed tube 222 to rotate 180 degrees, so that the front of the module faces upwards. This function realizes the automatic identification and flipping of the front and back of the LED module, avoiding manual intervention, improving the degree of production automation, and ensuring that the front of all modules entering the pasting process is consistent, which is beneficial to improving the quality and effect of adhesive application.

[0027] The feeding mechanism 30 includes a feeding tray 31 and a tensioning wheel 32. The adhesive backing is distributed on the feeding tray 31 in a roll shape and passes through the tensioning wheel 32.

[0028] Before starting the machine, the adhesive is manually pulled out from the feeding tray 31 and sent to the pasting mechanism 40 via the track set on the frame 10. Once the machine is started, the adhesive can be driven forward by the actions of the pasting mechanism 40 and the cutting mechanism 50.

[0029] The LED module's advanced feeding and correction component 21 for LED light strings has a structural design of a guiding space 213 that ensures that no matter what posture the LED light string takes when entering the spiral horn opening, it will be corrected in the guiding space 213 and exit in a rectangular shape.

[0030] The LED light string of the LED module has LED beads or lampshades on the front and a colloid plane on the back. When the LED light string comes out of the feeding and straightening component 21, it is in one of two states: one LED bead or lampshade face up, or the colloid plane on the back is face up. When the LED light string enters the flipping component 22, the infrared sensor detects the LED beads or lampshade and will not perform a flipping action. When the infrared sensor detects the colloid plane on the back, the rotating tube 222 will rotate 180 degrees so that the LED light string goes out with the LED beads or lampshade facing up.

[0031] The pasting mechanism 40 includes a clamping and rotating assembly 41 and a material feeding assembly 42. The clamping and rotating assembly 41 includes a horizontal movement drive device 411, a vertical movement drive device 412, a rotary drive cylinder 413, and a clamping cylinder 414. The vertical movement drive device 412 is installed at the output end of the horizontal movement drive device 411, the rotary drive cylinder 413 is installed at the output end of the vertical movement drive device 412, and the clamping cylinder 414 is installed at the output end of the rotary drive cylinder 413.

[0032] The transverse drive device 411 includes a transverse drive motor, a lead screw, and a sliding seat. The lead screw is mounted on the output end of the transverse drive motor and rotates in conjunction with the sliding seat.

[0033] The feeding assembly 42 includes a horizontal drive device 421, a vertical drive device 422, and a feeding plate 423. The horizontal drive device 421 is mounted on the frame 10, the vertical drive device 422 is mounted at the output end of the horizontal drive device 421, and the feeding plate 423 is mounted at the output end of the vertical drive device 422. The feeding plate 423 corresponds to the LED module.

[0034] The vertical drive device 412, the horizontal drive device 421 and the vertical drive device 422 all include a drive cylinder and a slider. The slider is installed at the output end of the drive cylinder and serves as the output end.

[0035] The horizontal movement drive device 411, vertical movement drive device 412, and rotary drive cylinder 413 of the clamping and rotating assembly 41 can achieve multi-dimensional position and angle adjustments, while the clamping cylinder 414 is used to securely clamp the LED module. This design allows the adhesive bonding mechanism 40 to flexibly adapt to LED modules of different specifications and sizes, accurately bonding the adhesive backing to the module. Through precise position and angle control, accurate and tight adhesive bonding is ensured, improving the quality and consistency of adhesive bonding.

[0036] The horizontal drive device 421, the vertical drive device 422, and the material-picking plate 423 of the material-picking assembly 42 cooperate with each other, with the material-picking plate 423 corresponding to the LED module. During the bonding process, the material-picking plate 423 can assist in the material-picking operation of the adhesive or LED module, ensuring smoother bonding between the adhesive and the module, avoiding problems such as wrinkles and bubbles, and further improving the quality of adhesive bonding.

[0037] The cutting mechanism 50 includes a displacement drive assembly 51, a cutting drive device 52, a slit drive device 53, and a cutting blade 54. The cutting drive device 52 is installed at the output end of the displacement drive assembly 51, the slit drive device 53 is installed at the output end of the cutting drive device 52, and the cutting blade 54 is installed at the output end of the slit drive device 53.

[0038] The displacement drive assembly 51 includes a clearance cylinder 511, a material transfer cylinder 512, and a longitudinal drive cylinder 513. The clearance cylinder 511 is mounted on the frame 10, the material transfer cylinder 512 is mounted at the output end of the clearance cylinder 511, the longitudinal drive cylinder 513 is mounted at the output end of the material transfer cylinder 512, and the cutting drive device 52 is mounted at the output end of the longitudinal drive cylinder 513.

[0039] The cutting drive device 52 includes a cutting drive cylinder, the shaving drive device 53 includes a shaving drive cylinder, the shaving drive cylinder is mounted at the output end of the cutting drive cylinder, the cutting blade 54 is mounted at the output end of the shaving drive cylinder, and the lower end of the cutting blade 54 is serrated.

[0040] The avoidance cylinder 511, material transfer cylinder 512 and longitudinal drive cylinder 513 of the displacement drive assembly 51 can realize the movement of the cutting drive device 52, the shaving drive device 53 and the cutting blade 54 in different directions.

[0041] The avoidance cylinder 511 allows the cutting mechanism 50 to avoid the work area when it is not in operation, thus avoiding interference with other processes. The transfer cylinder 512 can push the pasted LED module to the next workstation; the longitudinal drive cylinder 513 can adjust the longitudinal position of the cutting blade 54 to ensure accurate cutting. This multi-dimensional movement function enables the cutting mechanism 50 to adapt to different working scenarios and product specifications, improving the versatility and flexibility of the equipment.

[0042] The cutting drive cylinder of the cutting drive device 52 and the screed drive cylinder of the screed drive device 53 can respectively control the cutting blade 54 to perform screeding and cutting actions. Through program settings, the number of screeding and cutting can be adjusted according to actual needs, such as cutting once after each screeding. This design makes the cutting of adhesive backing more flexible and diverse, meeting the production requirements of different products. At the same time, the serrated cutting blade 54 can improve the cutting quality and efficiency, making the cutting edges neater.

[0043] The cutting mechanism 50 operates as follows: After the LED module string is attached to the adhesive backing, the transfer cylinder 512 and the avoidance cylinder 511 extend simultaneously to begin cutting the adhesive backing. Adhesive cutting involves two states: shaving and cutting. In the shaving state, only the shaving drive cylinder lowers the cutting blade 54. In the cutting state, both the shaving drive cylinder and the cutting drive cylinder operate simultaneously to completely cut the adhesive backing. The transfer cylinder 512 pushes the attached LED module to the next station. After one cut, the displacement drive component 51 drives the cutting drive device 52, the shaving drive device 53, and the cutting blade 54 to move, awaiting the next cut, repeating the process. A standard LED module string contains 20 LEDs per string; therefore, the number of cuts is set via a program, with one cutting action performed every 19 shavings. The program can also be adjusted to set different cutting counts as needed. Simultaneously with attaching the adhesive backing to the LED module string, the LED module string is also arranged.

[0044] The automatic adhesive application equipment for LED modules adopts a dual-channel symmetrical design, which can realize the identification and flipping of the front and back of the LED module, automatic feeding and application of LED modules and adhesive, and is compatible with a variety of products.

[0045] The length, width, and wiring of the LED light strings in the LED module vary, and the backing adhesive cutting also varies depending on the width of the LED light string product. The feeding and straightening component 21 and the flipping component 22 are universal for any rectangular product with LED beads or lampshades on the front. The clamping cylinder 414 is set with a clamp opening width to clamp LED light string products of different widths. The horizontal movement drive device 411 and the vertical movement drive device 412 can adjust the stroke according to the width of the LED light string product, so that each light string can be accurately moved to the pasting position for applying backing adhesive and cutting.

[0046] A system for an automatic adhesive backing device for LED modules includes a feeding module, a feeding module, an adhesive pasting module, a cutting module, and a control module. The feeding module, adhesive pasting module, and cutting module are all electrically connected to the control module. The feeding module has a feeding correction unit for position correction of the LED module and a flipping unit for detecting the front and back of the LED module and flipping it so that the front is facing up.

[0047] The feeding and straightening unit first precisely corrects the module's position to ensure accurate positioning. Then, the flipping unit uses sensors to detect the front and back of the module; if it's the back side, it automatically flips it over, ensuring all modules enter the next stage with their front side facing up. Simultaneously, the feeding module stably conveys rolls of adhesive tape to the pasting station. Next, the pasting module precisely aligns and applies the corrected, front-side-up LED module to the adhesive tape. After pasting, the platform carrying the module moves to the cutting module, where the cutting mechanism precisely cuts the tape to a preset length. Finally, the LED module with adhesive backing is output, completing the entire automated process. All these actions are uniformly coordinated and controlled by the control module, achieving highly efficient and consistent automated production.

[0048] An automatic adhesive application method for LED modules includes the following steps: First, a feeding mechanism feeds LED modules; Second, the feeding and straightening component corrects the position of the LED module, and the flipping component detects the front and back of the LED module and flips it so that the front is facing up; Third, the material supply mechanism supplies the adhesive backing material, which is in roll form; Fourth, the adhesive bonding mechanism applies adhesive to the back of the LED module; Fifth, the cutting mechanism cuts the adhesive backing of the LED modules.

[0049] The key design feature of this invention is that it achieves front and back identification and flipping of LED modules by employing a feeding and correction component and a flipping component. The automated feeding, pasting, and cutting of LED modules and adhesive backing through a feeding mechanism, a material supply mechanism, a pasting mechanism, and a cutting mechanism improves production efficiency and product quality. The automated feeding, pasting, and cutting of LED modules and adhesive backing reduces manual intervention and increases production efficiency. The feeding and correction component ensures accurate LED module positioning, the flipping component enables front and back identification and flipping, and the precise operation of the pasting and cutting mechanisms guarantees the quality of adhesive application and the neatness of the cuts. The automatic adhesive application equipment for LED modules provided in this application is applicable to LED modules of different sizes, offering a wide range of applications.
