Description

A light-emitting machine for encapsulating LED light sheets and LED light sheet production equipment Technical Field

[0001] This invention relates to the field of LED light sheet technology, specifically to a light irradiator and LED light sheet production equipment that applies potting compound to LED light sheets. Background Technology

[0002] In the manufacturing process of LED light sheets, key steps include die bonding, wire bonding, dispensing, beam splitting, and tape taping. Among these, the traditionally used epoxy or silicone adhesives in the dispensing stage suffer from poor adhesion and insufficient toughness, limiting product performance. To improve the toughness and overall performance of the adhesive layer in LED light sheets, the industry has begun to use UV adhesives as an alternative material. UV adhesives not only give the adhesive layer of LED light sheets higher toughness but also significantly improve the overall performance of LED light sheets due to their excellent light transmittance, superior stability, and good insulation properties, thereby optimizing the dispensing process for LED light sheets.

[0003] After the LED light sheet is coated with adhesive, it needs to be cured by ultraviolet light. However, the current practice usually requires the coated LED light sheet to be laid flat under the ultraviolet light manually, which not only wastes a lot of human resources, but also seriously affects production efficiency.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] Regarding the aforementioned problem that LED light sheets coated with UV adhesive are typically laid out manually and irradiated under ultraviolet light, which not only wastes a lot of manpower but also seriously affects production efficiency, the technical solution adopted by this invention to solve this problem is:

[0006] A light-irradiation machine for encapsulating LED light sheets includes an irradiation box. The irradiation box includes a placement part for placing LED light sheets, a curing part connected to the placement part, a transmission assembly located between the placement part and the curing part, a cover plate hinged to the curing part, and an ultraviolet light source mounted on the cover plate. When the LED light sheet on the placement part is transported to the curing part through the transmission assembly, the ultraviolet light source can irradiate the LED light sheet in the curing part. A handle block is also provided on the side of the cover plate away from the curing part.

[0007] Furthermore, the ultraviolet light source is located on the side of the cover plate near the curing part.

[0008] Furthermore, the curing part includes a first curing part disposed along a first direction, and the transmission component includes a first transmission mechanism extending along the length direction of the first curing part, and an auxiliary pushing mechanism located between the placement part and the first curing part and connected to the first transmission mechanism.

[0009] Furthermore, the curing section includes a second curing section disposed along the second direction, and the transmission assembly includes a second transmission mechanism that extends along the length direction of the second curing section and is connected to the first transmission mechanism.

[0010] Furthermore, the auxiliary pushing mechanism includes an auxiliary lifting mechanism located on the placement part and capable of moving up and down relative to the placement part in a third direction, a push rod capable of moving relative to the placement part in a first direction and passing through the auxiliary lifting mechanism, and an auxiliary conveyor belt located between the push rod and the first transmission mechanism.

[0011] Furthermore, the first transmission mechanisms are spaced apart along a first direction, and each of the first transmission mechanisms includes a base plate located above the first curing part, an electric roller that passes through the base plate and can rotate along the first direction, a first top block mechanism that can move relative to the base plate along a second direction and rise and fall in a third direction, a second top block mechanism that can move relative to the base plate along the first direction and rise and fall in a third direction, and a roller conveying bracket located on the side of the base plate away from the placement part.

[0012] Furthermore, the second transmission mechanism is spaced apart along the second direction and is correspondingly arranged with respect to the first transmission mechanism. Each of the second transmission mechanisms includes a conveyor belt mechanism and a limiting pin mechanism for restricting the movement of the LED light sheet and being able to move up and down relative to the second curing part along the third direction. The conveyor belt mechanism includes a first conveyor belt mechanism and a second conveyor belt mechanism corresponding to the first conveyor belt mechanism. An installation gap is provided between the first conveyor belt mechanism and the second conveyor belt mechanism. The limiting pin mechanism is spaced apart along the extension direction of the installation gap.

[0013] Furthermore, the first top block mechanism includes a first transverse top block mechanism and a second transverse top block mechanism symmetrically arranged with respect to the first transverse top block mechanism. The first transverse top block mechanism and the second transverse top block mechanism are respectively located on both sides of the bottom plate. The bottom plate is provided with transverse slots for the first transverse top block mechanism and the second transverse top block mechanism to move along the second direction.

[0014] The second top block mechanism includes a first longitudinal top block mechanism and a second longitudinal top block mechanism symmetrically arranged with respect to the first longitudinal top block mechanism. The first longitudinal top block mechanism and the second longitudinal top block mechanism are respectively located on the other two sides of the base plate. The base plate is provided with longitudinal slots for the first longitudinal top block mechanism and the second longitudinal top block mechanism to move along a first direction.

[0015] Furthermore, the light-emitting box is also provided with an exhaust hole that connects to the outside.

[0016] The present invention also provides LED light sheet production equipment, including a light irradiator for applying LED light sheet potting compound as described above.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention, by setting up a placement section, a curing section, a transmission component located between the placement section and the curing section, and an ultraviolet light source, allows users to place the LED light sheet on the placement section after it has been glued with UV adhesive. The transmission component automatically transports the LED light sheet from the placement section to the curing section, so that the ultraviolet light source can irradiate the LED light sheet on the curing section, thereby curing the glued LED light sheet. This reduces manual intervention and improves the automation level of the LED light sheet production process. It effectively solves the problem that existing methods of manually laying out LED light sheets after UV adhesive dispensing and irradiating them under ultraviolet light not only waste a lot of human resources but also seriously affect production efficiency.

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0032] As shown in Figures 1 to 11, a light-irradiation machine for encapsulating LED light sheets includes an illumination box 1. The illumination box 1 includes a placement part 2 for placing LED light sheets, a curing part 3 connected to the placement part 2, a transmission assembly 4 located between the placement part 2 and the curing part 3, a cover plate 11 hinged to the curing part 3, and an ultraviolet light source mounted on the cover plate 11. When the LED light sheet on the placement part 2 is transported to the curing part 3 through the transmission assembly 4, the ultraviolet light source can irradiate the LED light sheet in the curing part 3. A handle block 10 is also provided on the side of the cover plate 11 away from the curing part 3.

[0033] This invention, by setting up a placement section, a curing section, a transmission component located between the placement section and the curing section, and an ultraviolet light source, allows users to place the LED light sheet on the placement section after it has been glued with UV adhesive. The transmission component automatically transports the LED light sheet from the placement section to the curing section, so that the ultraviolet light source can irradiate the LED light sheet on the curing section, thereby curing the glued LED light sheet. This reduces manual intervention and improves the automation level of the LED light sheet production process. It effectively solves the problem that existing methods of manually laying out LED light sheets after UV adhesive dispensing and irradiating them under ultraviolet light not only waste a lot of human resources but also seriously affect production efficiency.

[0034] Furthermore, the first direction corresponds to the X-axis direction (front and back direction), the second direction corresponds to the Y-axis direction (left and right direction), and the third direction corresponds to the Z-axis direction (up and down direction).

[0035] Specifically, in the LED light sheet production process, firstly, UV adhesive is applied to the LED light sheet. Then, the adhesive-coated LED light sheet is placed in the placement section 2 on the light box 1. Under the action of the transmission component 4, the LED light sheets located in the placement section 2 are transported one by one and laid flat on the curing section 3, so that the ultraviolet light source on the light box 1 can irradiate the LED light sheets laid flat on the curing section 3, thereby curing the adhesive-coated LED light sheet. After the ultraviolet light source irradiation ends, the transmission component can automatically transport the LED light sheets laid flat on the curing section back to the placement section one by one. Finally, the user can collect the LED light sheets located in the placement section.

[0036] Optionally, in other embodiments, the transmission component includes an auxiliary pushing mechanism 40 and a second transmission mechanism 42. The second transmission mechanism 42 is located within the curing section and is spaced apart. Each second transmission mechanism 42 corresponds to an auxiliary pushing mechanism 40. Each auxiliary pushing mechanism 40 includes an auxiliary lifting mechanism located on the placement section 2 and movable relative to the placement section 2 along the Z-axis, a push rod 401 movable relative to the placement section 2 along the X-axis and passing through the auxiliary lifting mechanism, and an auxiliary conveyor belt 402. The auxiliary lifting mechanism is provided with a material box for placing LED light sheets. The LED light sheets are spaced apart in the material box along the Z-axis. Each second transmission mechanism 42 includes a first conveyor belt mechanism 4211, a second conveyor belt mechanism 4212 symmetrically arranged with the first conveyor belt mechanism 4211, and a limiting ejector pin mechanism 422. An installation gap 4213 is provided between the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. The limiting ejector pin mechanism 422 is spaced apart along the extension direction of the installation gap 4213. The setup is as follows: when push rod 401 pushes the LED sheets in the material box one by one to auxiliary conveyor belt 402, the LED sheets can be transferred between the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 under the action of the auxiliary conveyor belt 402. Under the action of the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212, the LED sheets move to the corresponding positions on the curing part. The limiting pin mechanism 422 rises along the Z-axis direction. The two adjacent limiting pin mechanisms 422 can restrict the movement of the LED sheets, thereby fixing the LED sheets to the corresponding positions on the curing part. When the LED sheets cover the surface of the curing part, the LED sheets are irradiated with ultraviolet light source to cure the LED sheets after dispensing. After irradiation, the limiting pin mechanism 422 descends along the Z-axis direction. The first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 transport the LED sheets back to the auxiliary conveyor belt 402 in sequence. The auxiliary conveyor belt 402 transports the LED sheets back to the material box in sequence, and finally, they are taken away by the user.

[0037] Optionally, in other embodiments, the transmission assembly includes an auxiliary pushing mechanism 40 and a first transmission mechanism 41. The first transmission mechanism 41 is located within the curing section and is spaced apart. Each first transmission mechanism 41 corresponds to an auxiliary pushing mechanism 40. Each auxiliary pushing mechanism 40 includes an auxiliary lifting mechanism located on the placement section 2 and movable relative to the placement section 2 along the Z-axis, a push rod 401 movable relative to the placement section 2 along the X-axis and passing through the auxiliary lifting mechanism, and an auxiliary conveyor belt 402 located between the push rod 401 and the first transmission mechanism 41. The auxiliary lifting mechanism is provided with a material box for placing LED light sheets. The LED light sheets are spaced apart in the material box along the Z-axis. Each first transmission mechanism 41 includes a base plate 411. The system includes an electric roller 412 that penetrates the base plate 411 and can rotate along the X-axis, a second top block mechanism 414, and a roller conveyor bracket 415. The second top block mechanism 414 can move up and down relative to the base plate 411 along the Z-axis and along the X-axis. The second top block mechanism 414 includes a first longitudinal top block mechanism 4141 and a second longitudinal top block mechanism 4142 symmetrically arranged with the first longitudinal top block mechanism 4141. The second longitudinal top block mechanism 4142 is located between the base plate 411 and the roller conveyor bracket 415. When the push rod 401 pushes the LED light sheets in the material box one by one to the auxiliary conveyor belt 402, the LED light sheets can be transferred to the base plate 411 under the action of the auxiliary conveyor belt 402. The first longitudinal top block mechanism 4141 rises along the Z-axis to restrict the movement of the LED sheet. When the LED sheet needs to be transported from one base plate 411 to the next base plate 411, the first longitudinal top block mechanism 4141 rises along the Z-axis and moves along the X-axis towards the side of the base plate 411, thereby pushing the LED sheet towards the roller conveyor bracket 415. At this time, the second longitudinal top block mechanism 4142 does not rise along the Z-axis, and the roller conveyor bracket 415 rolls, cooperating with the electric roller 412 to transport the LED sheet from one base plate 411 to the next base plate 411. At this time, the first longitudinal top block mechanism 4141 on the next base plate 411 does not rise along the Z-axis, and the second longitudinal top block mechanism 4142 rises along the Z-axis to restrict the movement of the LED sheet. The movement of the LED sheet involves the following steps: When the LED sheet covers the surface of the curing section, it is irradiated with ultraviolet light to cure the applied adhesive. After irradiation, the roller conveyor bracket 415 and the electric roller 412 roll in opposite directions, causing the LED sheet on the next base plate 411 to move towards the previous base plate 411. During this process, the second longitudinal top block mechanism 4142 on the next base plate 411 rises along the Z-axis and moves towards the previous base plate 411 along the X-axis, while the first longitudinal top block mechanism 4141 does not rise along the Z-axis. The roller conveyor bracket 415 rolls in conjunction with the electric roller 412, ensuring that the irradiated LED sheet is transported from the next base plate 411 to the previous base plate 411.The second longitudinal top block mechanism 4142 on the first base plate 411 rises along the Z-axis and moves along the X-axis towards the auxiliary conveyor belt 402, while the first longitudinal top block mechanism 4141 does not rise along the Z-axis. The LED light sheets are sequentially transported back to the auxiliary conveyor belt 402, which then sequentially transports the LED light sheets back to the material box for final collection by the user.

[0038] Optionally, in other embodiments, the transmission component 4 includes an auxiliary pushing mechanism 40, a first transmission mechanism 41, and a second transmission mechanism 42. The auxiliary pushing mechanism 40 and the first transmission mechanism 41 are connected. The first transmission mechanism 41 is located on one side of the curing part and is spaced apart along the X-axis. The second transmission mechanism 42 is spaced apart along the Y-axis and is correspondingly arranged with the first transmission mechanism 41. The auxiliary pushing mechanism 40 includes an auxiliary lifting mechanism located on the placement part 2 and capable of lifting and lowering relative to the placement part 2 along the Z-axis, a push rod 401 movable relative to the placement part 2 along the X-axis and passing through the auxiliary lifting mechanism, and an auxiliary conveyor belt 402 located between the push rod 401 and the first transmission mechanism 41. The lifting mechanism is equipped with a material box for placing LED light sheets. The LED light sheets are spaced apart in the material box along the Z-axis. The first transmission mechanism 41 includes a base plate 411, an electric roller 412 that passes through the base plate 411 and can rotate along the X-axis, a first top block mechanism 413, a second top block mechanism 414, and a roller conveying bracket 415. The first top block mechanism 413 is located on the side away from the second transmission mechanism 42. The first top block mechanism 413 can be lifted and lowered along the Z-axis and moved along the Y-axis. The second top block mechanism 414 includes a first longitudinal top block mechanism 4141 and a second longitudinal top block mechanism 4142 symmetrically arranged with the first longitudinal top block mechanism 4141. 142 is located between the base plate 411 and the roller conveyor bracket 415. Both the first longitudinal top block mechanism 4141 and the second longitudinal top block mechanism 4142 can move up and down along the Z-axis and along the X-axis. The second transmission mechanism 42 includes a first conveyor belt mechanism 4211, a second conveyor belt mechanism 4212 symmetrically arranged with the first conveyor belt mechanism 4211, and a limiting pin mechanism 422. An installation gap 4213 is provided between the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. The limiting pin mechanisms 422 are spaced apart along the extension direction of the installation gap 4213. When the push rod 401 pushes the LED light sheets in the material box one by one to the auxiliary conveyor belt 402, on the auxiliary conveyor belt 4... Under the action of 02, the LED light sheet can be transferred to the base plate 411. When the LED light sheet is transported from the base plate 411 to the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212, the first top block mechanism 413 rises along the Z-axis and moves along the Y-axis towards the second transmission mechanism 42, thereby pushing the LED light sheet to move between the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. Under the action of the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212, it moves to the corresponding position on the second curing part 32. The limiting pin mechanism 422 rises along the Z-axis. The two adjacent limiting pin mechanisms 422 can restrict the movement of the LED light sheet.When the LED sheet is conveyed from one base plate 411 to the next base plate 411, the first longitudinal top block mechanism 4141 rises along the Z-axis and moves along the X-axis towards the side of the base plate 411, thereby pushing the LED sheet towards the roller conveyor bracket 415. At this time, the second longitudinal top block mechanism 4142 does not rise along the Z-axis, and the roller conveyor bracket 415 rolls, cooperating with the electric roller 412 to convey the LED sheet from one base plate 411 to the next base plate 411. At this time, the first longitudinal top block mechanism 4141 on the next base plate 411 does not rise along the Z-axis, and the second longitudinal top block mechanism 4142 rises along the Z-axis to restrict the movement of the LED sheet. When the LED sheet covers the surface of the curing section, the LED sheet is irradiated with an ultraviolet light source to cure the LED sheet after dispensing.

[0039] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the auxiliary pushing mechanism 40 and the first transmission mechanism 41 are connected and both are located in the middle of the curing section. The second transmission mechanism 42 is located on both sides of the first transmission mechanism 41 and is spaced apart along the Y-axis. The auxiliary pushing mechanism 40 includes an auxiliary lifting mechanism located on the placement section 2 and capable of moving up and down relative to the placement section 2 along the Z-axis, a push rod 401 movable relative to the placement section 2 along the X-axis and passing through the auxiliary lifting mechanism, and an auxiliary conveyor belt 402 located between the push rod 401 and the first transmission mechanism 41. The auxiliary lifting mechanism is provided with a material box for placing LED light sheets. The first transmission mechanism 41, arranged at intervals along the Z-axis within the material box, includes a base plate 411, an electric roller 412 that penetrates the base plate 411 and can rotate along the X-axis, a first top block mechanism 413, a second top block mechanism 414, and a roller conveyor bracket 415. The first top block mechanism 413 includes a first transverse top block mechanism 4131 and a second transverse top block mechanism 4132. The second top block mechanism 414 includes a first longitudinal top block mechanism 4141 and a second longitudinal top block mechanism 4142. The second transmission mechanism 42 includes a first conveyor belt mechanism 4211, a second conveyor belt mechanism 4212 symmetrically arranged with the first conveyor belt mechanism 4211, and a limiting... The positioning pin mechanism 422, the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 are provided with an installation gap 4213, and the positioning pin mechanism 422 is spaced apart along the extension direction of the installation gap 4213. When the push rod 401 pushes the LED light sheets in the material box one by one to the auxiliary conveyor belt 402, the LED light sheets can be transferred to the base plate 411 under the action of the auxiliary conveyor belt 402. If the LED light sheets are conveyed from the base plate 411 to the left between the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212, the first transverse top block mechanism 4131 rises along the Z-axis and moves closer to the second transmission mechanism 4212 on the left along the Y-axis. When the LED sheet moves from the base plate 411 to the right side between the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212, the second transverse top block mechanism 4132 rises along the Z-axis and moves along the Y-axis towards the right side of the second transmission mechanism 42. The first transverse top block mechanism 4131 does not rise along the Z-axis, thus pushing the LED sheet to move towards the right side of the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212.When the LED sheet is conveyed from one base plate 411 to the next base plate 411, the first longitudinal top block mechanism 4141 rises along the Z-axis and moves along the X-axis towards the side of the base plate 411, thereby pushing the LED sheet towards the roller conveyor bracket 415. At this time, the second longitudinal top block mechanism 4142 does not rise along the Z-axis, and the roller conveyor bracket 415 rolls, cooperating with the electric roller 412 to convey the LED sheet from one base plate 411 to the next base plate 411. At this time, the first longitudinal top block mechanism 4141 on the next base plate 411 does not rise along the Z-axis, and the second longitudinal top block mechanism 4142 rises along the Z-axis to restrict the movement of the LED sheet.

[0040] Furthermore, the cover plate 11 is hinged to the curing part 3, and the user can lift the cover plate 11 upward along the Z-axis direction using the handle block 10, so that one side of the cover plate 11 is separated from the curing part 3, thereby forming an opening, which is beneficial for the user to clean and maintain the light box 1.

[0041] As shown in Figures 1 to 11, the ultraviolet lamp source is located on the side of the cover plate 11 near the curing part 3;

[0042] Specifically, the ultraviolet light source is located on the side of the cover plate 11 near the curing section 3, and the area of ​​the ultraviolet light source is equal to the cross-sectional area of ​​the cover plate 11, which is beneficial to improve the irradiation effect of the ultraviolet light source on the LED sheet and effectively improve the curing efficiency.

[0044] Specifically, the first curing part 31 is arranged along the X-axis direction, the first transmission mechanism 41 is arranged at intervals along the extension direction of the first curing part 31, and the auxiliary pushing mechanism 40 is arranged between the placement part 2 and the first curing part 31, so that the LED light sheet after dispensing and located on the placement part 2 can be transported to the first transmission mechanism 41 on the first curing part 31 by the auxiliary pushing mechanism 40.

[0045] As shown in Figures 1 to 11, the curing part 3 includes a second curing part 32 disposed along the second direction, and the transmission component 4 includes a second transmission mechanism 42 that extends along the length direction of the second curing part 32 and is connected to the first transmission mechanism 41.

One first transmission mechanism 41 corresponds to two second transmission mechanisms 42 on the left and right sides of the same Y-axis.

[0047] Furthermore, a gap is provided between the first transmission mechanism 41 and the second transmission mechanism 42.

[0049] Specifically, the auxiliary lifting mechanism includes an auxiliary lifting motor and an auxiliary lifting frame connected to the auxiliary lifting motor. The material box is located inside the auxiliary lifting frame. When the auxiliary lifting motor operates, the auxiliary lifting frame can move up and down along the Z-axis, thereby driving the material box to move up and down along the Z-axis. LED light sheets are spaced apart in the material box along the Z-axis. The auxiliary lifting frame passes through the placement part 2 along the Z-axis. When it is necessary to push LED light sheets onto the auxiliary conveyor belt 402, the push rod 401 pushes out towards the X-axis near the curing part, thereby pushing the bottom layer of LED light sheets in the material box toward the auxiliary conveyor belt 402. At this time, the auxiliary lifting motor... Under the action of the machine, the auxiliary lifting frame descends one layer along the Z-axis, and the material box descends one layer along the Z-axis, so that the push rod 401 can sequentially transport the LED light sheets in the material box to the auxiliary conveyor belt 402 one by one; after the light curing is completed, the LED light sheets are conveyed to the auxiliary conveyor belt 402 one by one. Under the action of the auxiliary conveyor belt 402, the LED light sheets are transported back into the material box. At this time, the LED light sheets are located on the top layer of the material box. Under the action of the auxiliary lifting motor, the material box rises one layer along the Z-axis, so that the LED light sheets located on the auxiliary conveyor belt 402 can return to the material box one by one. Finally, the user can take away the material box.

[0050] As shown in Figures 1 to 11, the first transmission mechanism 41 is arranged at intervals along the first direction. Each first transmission mechanism 41 includes a base plate 411 located above the first curing part 31, an electric roller 412 that passes through the base plate 411 and can rotate along the first direction, a first top block mechanism 413 that can move relative to the base plate 411 along the second direction and rise and fall in the third direction, a second top block mechanism 414 that can move relative to the base plate 411 along the first direction and rise and fall in the third direction, and a roller conveying bracket 415 located on the side of the base plate 411 away from the placement part 2.

[0051] Specifically, the base plate 411 is located above the first curing part 31, and the electric rollers 412 pass through the base plate 411 and are spaced apart. The cross-section of the electric rollers 412 is rectangular and can rotate forward or backward along the X-axis. Similarly, the roller conveying bracket 415 can also rotate forward or backward along the X-axis.

[0052] Optionally, the bottom of the curing section is provided with a connecting shaft and a drive motor for connecting several electric rollers 412. The output end of the drive motor is connected to the connecting shaft. When the drive motor is operating normally, the connecting shaft drives the electric rollers to rotate. A connecting shaft and a drive motor are also provided below the roller conveying bracket 415. When the drive motor is operating normally, the connecting shaft drives the roller conveying bracket 415 to roll. The first top block mechanism 413 includes a first top block, a first cylinder that can extend and retract along the Z-axis, and a second cylinder connected to the first cylinder that can extend and retract along the Y-axis. The first top block can be raised and lowered along the Z-axis by the first cylinder and can be moved along the Y-axis by the second cylinder. Similarly, the second top block mechanism 414 includes a second top block, a first cylinder that can extend and retract along the Z-axis, and a third cylinder connected to the first cylinder that can extend and retract along the X-axis. The second top block can be raised and lowered along the Z-axis by the first cylinder and can be moved along the X-axis by the third cylinder.

[0053] As shown in Figures 1 to 11, the second transmission mechanism 42 is arranged at intervals along the second direction and is corresponding to the first transmission mechanism 41. Each second transmission mechanism 42 includes a conveyor belt mechanism 421 and a limiting pin mechanism 422 for restricting the movement of the LED light sheet and being able to rise and fall relative to the second curing part 32 along the third direction. The conveyor belt mechanism 421 includes a first conveyor belt mechanism 4211 and a second conveyor belt mechanism 4212 corresponding to the first conveyor belt mechanism 4211. An installation gap 4213 is provided between the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. The limiting pin mechanism 422 is arranged at intervals along the extension direction of the installation gap 4213.

[0054] Specifically, both the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 have gaps on the side near the first transmission mechanism 41.

[0055] Optionally, the bottom of the curing section is provided with a connecting shaft and a drive motor for connecting the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. The output end of the drive motor is connected to the connecting shaft. When the drive motor is operating normally, the connecting shaft drives the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 to rotate synchronously to the left or right along the Y-axis. The limiting pin mechanism 422 includes a plurality of first cylinders that can extend and retract along the Z-axis located on the mounting gap 4213, and limiting pins connected to the first cylinders. The limiting pins can rise and fall along the Z-axis through the first cylinders, thereby limiting the movement of the LED light sheet.

[0056] As shown in Figures 1 to 11, the first top block mechanism 413 includes a first transverse top block mechanism 4131 and a second transverse top block mechanism 4132 symmetrically arranged with the first transverse top block mechanism 4131. The first transverse top block mechanism 4131 and the second transverse top block mechanism 4132 are respectively located on both sides of the base plate 411. The base plate 411 is provided with a transverse slot 4111 for the first transverse top block mechanism 4131 and the second transverse top block mechanism 4132 to move along a second direction.

[0057] The second top block mechanism 414 includes a first longitudinal top block mechanism 4141 and a second longitudinal top block mechanism 4142 symmetrically arranged with the first longitudinal top block mechanism 4141. The first longitudinal top block mechanism 4141 and the second longitudinal top block mechanism 4142 are respectively located on the other two sides of the base plate 411. The base plate 411 is provided with a longitudinal slot 4112 for the first longitudinal top block mechanism 4141 and the second longitudinal top block mechanism 4142 to move along a first direction.

[0058] Specifically, the first transverse top block mechanism 4131, the second transverse top block mechanism 4132, the first longitudinal top block mechanism 4141, and the second longitudinal top block mechanism 4142 are all located on the outside of the base plate 411 and correspond to the four sides of the base plate 411 respectively. When the first transverse top block mechanism 4131, the second transverse top block mechanism 4132, the first longitudinal top block mechanism 4141, and the second longitudinal top block mechanism 4142 rise along the Z-axis direction, none of them will lift the LED light sheet on the base plate 411. When one of the two mechanisms 4131 and 4142 moves along the Y-axis towards the transverse slot 4111 to push the LED sheet towards the second transmission mechanism 42, the other of the two mechanisms 4131 and 4132 will not rise along the Z-axis; similarly, when one of the two mechanisms 4141 and 4142 moves along the X-axis towards the longitudinal slot 4112 to push the LED sheet, the other of the two mechanisms 4141 and 4142 will not rise along the Z-axis.

[0059] As shown in Figures 1 to 11, the light box 1 is also provided with an exhaust hole 12 that communicates with the outside.

[0060] Specifically, the light-emitting box 1 has several vents 12 connected to the outside. The vents 12 allow air exchange between the inside of the light-emitting box 1 and the outside. When the UV light source irradiates the LED sheet, the UV adhesive reacts with the UV light to produce adhesive gas. If these gases are not discharged in time, they will accumulate inside the light-emitting box 1, affecting the UV light irradiation effect and the curing quality of the UV adhesive. By setting the vents 12, these harmful gases can be effectively discharged, thereby maintaining air circulation and freshness inside the light-emitting box 1. Secondly, during the UV adhesive curing process, good air circulation helps to accelerate the curing speed and improve the curing quality. The vents 12 can accelerate the air flow inside the light-emitting box 1, promote the reaction between the UV adhesive and oxygen in the air, and thus accelerate the curing process.

[0061] The LED sheet production equipment shown in Figures 1 to 11 includes a light irradiator for applying LED sheet potting compound as described above.

[0062] Specifically, the production equipment includes a dispensing device, a curing device, an inspection and stripping device, and a transmission track mechanism 5 for connecting the dispensing device, the curing device, and the inspection and stripping device. The dispensing device is used to dispense adhesive onto LED light sheets. After dispensing, the LED light sheets can be transported to the curing device for curing via the transmission track mechanism 5. After curing, the LED light sheets are transported to the inspection and stripping device via the transmission track mechanism 5. The inspection and stripping device can quickly and accurately identify the quality of the LED light sheets and strip off defective products. LED light sheets without defects are cut into individual finished LED beads.

[0063] Optionally, in other embodiments, the dispensing equipment is a dispensing machine 6 located above the transmission track mechanism 5 and arranged vertically, a dispensing machine feeding mechanism 61 located on one side of the dispensing machine 6, and a dispensing machine discharging mechanism 62 located on the other side of the dispensing machine 6. The dispensing machine 6 includes an air pump, an air pipe, a glue cylinder, a glue inlet block, and a dispensing head. One end of the glue cylinder is connected to the air pump through the air pipe, and the other end of the glue cylinder is connected to the dispensing head through the glue inlet block. The glue cylinder is used to store UV glue. After the air pump is turned on, the air pressure generated by the air pump is delivered to the top of the glue cylinder through the air pipe and applies pressure to the UV glue in the glue cylinder so that the UV glue enters the glue inlet block. The glue inlet block can initially control the flow direction and flow rate of the UV glue and has a certain limiting and guiding effect on the UV glue. Under the action of the glue inlet block, the UV glue is transferred to the dispensing head. Under the continuous push of the air pressure, the UV glue is squeezed out from the dispensing head and finally drips onto the position where the LED light sheet needs to be glued. Furthermore, the dispensing machine feeding mechanism 61 includes a feeding drive motor that can be raised and lowered along the Z-axis, a feeding lifting frame connected to the feeding drive motor, and a feeding push rod that passes through the feeding lifting frame. The dispensing machine dispensing mechanism 62 includes a dispensing drive motor and a dispensing lifting frame connected to the dispensing drive motor. The material box is located in the feeding lifting frame and the dispensing lifting frame, respectively.

[0064] Optionally, an air pump is connected to several glue cartridges via several air pipes, and the glue cartridges are connected to several dispensing heads via a dispensing block. One air pump can provide power to multiple glue cartridges simultaneously. Compared to equipping each glue cartridge with an air pump, connecting multiple glue cartridges with one air pump via several air pipes helps reduce the number of air pumps, which helps reduce equipment costs and saves space. Secondly, since the UV glue supply to all dispensing heads needs to pass through the same dispensing block, it helps ensure that the UV glue coming out of each dispensing head has a high degree of consistency in terms of flow rate and pressure, which helps to ensure the uniformity and stability of the dispensing effect and effectively reduces the defect rate of LED light sheets.

[0065] Optionally, in other embodiments, the curing equipment includes a UV lamp 71 located above the transport track mechanism and capable of providing ultraviolet light. The UV lamp 71 includes a mounting integrated plate and several UV lamps located on the side of the mounting integrated plate near the transport track mechanism. The UV lamps are arranged along the extension direction of the mounting integrated plate. When the LED sheet dispensing by the dispensing machine 6 is transported to the area below the UV lamp 71 under the action of the transport track mechanism 5, the ultraviolet light can quickly irradiate the adhesive on the LED sheet, achieving rapid curing. This not only improves production efficiency but also ensures the curing quality of the UV adhesive, thereby improving the overall performance of the LED sheet. Secondly, since the UV lamps are arranged along the extension direction of the mounting integrated plate, when the LED sheet passes under the UV lamp 71 under the action of the transport track mechanism 5, it can receive ultraviolet light irradiation more evenly, which helps to ensure that the adhesive at the dispensing point of the LED sheet is uniformly cured on the entire sheet, avoiding incomplete or over-cured areas. Finally, placing the UV lamp 71 above the transport track mechanism 5 makes full use of vertical space and avoids occupying ground space.

[0066] Optionally, in other embodiments, the curing device includes a light-emitting box 1 and a mounting frame 70 for placing the light-emitting box 1. Several light-emitting boxes 1 can be placed simultaneously in the mounting frame 70 in a vertical direction. The mounting frame 70 not only provides placement space for several light-emitting boxes 1, but also provides power to each light-emitting box 1. After the LED light sheet is dispensed by the dispensing machine 6, the material box is collected manually and placed on each light-emitting box 1. The light-emitting box 1 can automatically transport the LED light sheet in the material box to the light-emitting box 1 for light irradiation, thereby curing the UV adhesive. After irradiation, the light-emitting box 1 automatically transports the LED light sheet laid flat in the light-emitting box 1 out. The LED light sheet returns to the material box one by one and is finally collected and processed manually.

[0067] Optionally, in other embodiments, the curing equipment includes a dehumidifying oven 72. After being irradiated by the light box 1, the LED light sheets are manually collected in a material box and placed into the dehumidifying oven 72 for dehumidification and heating. The dehumidifying oven 72 can effectively remove residual moisture from the LED light sheets, ensuring that the dryness of the LED light sheets meets the standards. Secondly, the dehumidifying oven 72 has a highly efficient energy utilization and heat recovery system, which can minimize energy consumption while ensuring the dehumidification effect. In addition, since the dehumidifying oven 72 can process multiple LED light sheets at the same time, batch processing can be achieved, further reducing production costs.

[0068] Optionally, in other embodiments, the curing equipment includes a baking tunnel oven 73 connected to the conveying track mechanism 5. The baking tunnel oven 73 includes an oven body, a baking material conveying mechanism that runs through the oven body, a heating device located inside the oven body, an air supply device, and a tunnel oven control system. The baking material conveying mechanism is connected to the conveying track mechanism 5 on both sides with gaps, so that the LED light sheets are conveyed into the oven body for baking and heating, and the baked and heated LED light sheets are conveyed out of the oven body. The baking material conveying mechanism can be a conveyor belt or roller conveyor, etc. The heating device can be one of electric heating, gas heating, or natural gas heating, preferably electric heating. The air supply device includes a fan, an air inlet pipe, and an air outlet pipe. The air supply device is used to introduce external air into the oven body and exhaust the exhaust gas inside the oven body. The tunnel oven control system includes a tunnel oven control host. Users can precisely adjust parameters such as the temperature inside the oven body, the rotation speed of the baking material conveying mechanism, and the air volume through the tunnel oven control host to ensure the baking and heating effect of the LED light sheets.

[0069] Optionally, in other embodiments, the stripping and inspection equipment includes an AOI inspection device 81. The AOI inspection device 81 includes an optical imaging system, an AOI mechanical motion system, and an image processing system. The optical imaging system includes a light source for detecting the quality of LED sheets, an optical lens for collecting reflected light from the surface of the LED sheets, and an image sensor. The AOI mechanical motion system includes a stage for placing the LED sheets to be inspected and a stripping mechanism for removing defective products. The image processing system includes an image acquisition card and an AOI computer. The stage is connected to the transfer track mechanism 5 with a gap. Under the action of the transfer track mechanism 5, the LED sheets are transported to the stage. The stage can move precisely in both horizontal and vertical directions to comprehensively inspect different areas of the LED sheets. Typically, a high-precision AOI is used. Precision motors, lead screws, guide rails, and other components work together to enable relative movement of the stage. The light source provides the light required for detection, and an optical lens collects the light reflected from the surface of the LED sheet and focuses it onto an image sensor. The image sensor converts the light signal into a digital signal, which is then transmitted to an AOI computer via an image acquisition card. The AOI computer has functions such as image analysis, feature extraction, and defect identification. Through algorithms, it compares the acquired image with a pre-set standard image or model to determine whether there are any abnormalities in the LED sheet. If an abnormality is found, the AOI computer controls the peeling mechanism to move to a designated position and applies appropriate force to peel the abnormal LED sheet from the substrate. The peeling mechanism can be a suction cup, gripper, or other mechanical mechanism. Finally, the output is an LED sheet without any abnormalities.

[0070] Optionally, in other embodiments, the stripping and detection equipment includes a lead-cutting machine 82 for cutting LED sheets into individual finished LED beads. The lead-cutting machine 82 includes a feeding mechanism connected to the transmission track mechanism 5, a cutting table connected to the feeding mechanism, a cutting mechanism, a limiting cutting mechanism, a waste disposal mechanism, a discharge mechanism, and a cutting control host. There is a gap between the transmission track mechanism 5 and the feeding mechanism, which can transmit the LED sheets to the feeding mechanism. The feeding mechanism can ensure that the LED sheets enter the cutting table continuously and stably. The limiting cutting mechanism is located on the cutting table and is used to ensure the accuracy of the position of the LED sheets during the cutting process. The limiting cutting mechanism is formed by a combination of a cutting limiting plate and a cutting limiting pin. The cutting control host is used to realize the automated operation and precise control of the equipment. The cutting control host realizes the precise control of parameters such as cutting speed and cutting depth through programming, thereby controlling the cutting mechanism to cut the LED sheets. The cutting mechanism is formed by the cooperation of components such as a cutting motor, a cutter, and a bracket. Finally, the discharge mechanism transports the individual finished LED beads to the outside of the cutting table for collection by the user. In addition, the waste disposal mechanism includes a waste channel connected to the cutting table and a waste box connected to the waste channel. Waste generated during the LED light sheet cutting process enters the waste box through the waste channel, which helps to ensure the cleanliness and safety of the working environment of the lead cutting machine.

[0071] The LED light sheet manufacturing process, as shown in Figures 1 to 11, includes the following steps:

[0072] S1: The LED light sheet is transported to the dispensing equipment via the transmission track mechanism 5. The dispensing equipment drips UV glue onto the LED light sheet, thus completing the dispensing process.

[0073] S2: Place the LED sheet after dispensing the adhesive onto the curing equipment, and use the curing equipment to cure the UV adhesive on the LED sheet;

[0074] S3: Place the cured LED sheet on the inspection and stripping equipment. The inspection and stripping equipment quickly and accurately identifies the quality of the LED sheet and strips off defective products. The LED sheets without defects are cut into individual finished LED beads.

[0075] Optionally, in some other embodiments, step S1 further includes the following step:

[0076] S11: The feeding pusher in the feeding mechanism 61 of the dispensing machine pushes the LED light sheet in the material box to the transmission track mechanism 5. The feeding drive motor drives the feeding lifting frame to rise and fall along the Z-axis direction. The material box in the feeding lifting frame rises and falls synchronously, so that the feeding pusher conveys the LED light sheet to the transmission track mechanism 5 one by one. The transmission track mechanism 5 conveys each LED light sheet to the bottom of the dispensing machine 6 for the dispensing machine 6 to dispense the LED light sheet. The average dispensing time of the dispensing machine 6 for a single LED light sheet is 8 seconds to 10 seconds. The LED light sheets after dispensing are conveyed to the curing equipment in sequence under the action of the transmission track mechanism 5.

[0077] Step S2 also includes the following steps:

[0078] S21: The curing equipment is a UV light lamp 71. The UV light lamp 71 provides ultraviolet light to irradiate the LED light sheet located on the transmission track mechanism 5 for 20-30 seconds. After the irradiation is completed, the LED light sheet is sequentially transported to the detection and stripping equipment through the transmission track mechanism 5.

[0079] Step S3 also includes the following steps:

[0080] S31: The stripping and stripping equipment includes an AOI inspection device 81 and a lead cutter 82. Under the action of the transmission track mechanism 5, the LED light sheet is transported to the platform. The light source in the AOI inspection device 81 illuminates the surface of the LED light sheet. The optical lens collects the light reflected from the surface of the LED light sheet and focuses it onto the image sensor. The image sensor can convert the light signal into a digital signal. Under the action of the image acquisition card, the digital signal is transmitted to the AOI computer. The AOI computer identifies and determines whether the quality of the LED light sheet is abnormal and controls the stripping mechanism to strip the abnormal light sheet. The remaining qualified LED light sheets are transported to the lead cutter 82 through the transmission track mechanism 5.

[0081] S32: The transmission track mechanism 5 transmits the LED light sheet to the feeding mechanism in the lead cutting machine 82. The LED light sheet is transmitted to the cutting table through the feeding mechanism. The limiting cutting mechanism restricts the position of the LED light sheet on the cutting table. The cutting control host controls the cutting mechanism to cut the LED light sheet into a single finished LED bead.

[0082] Furthermore, compared to the traditional method of applying epoxy or silicone adhesive and then curing the LED sheet in an oven, which requires 5 hours of oven heating (including 1 hour at 80°C and 4 hours at 160°C), this invention uses UV adhesive for dispensing and then UV light lamp 71 for curing. The curing time is only about 40 seconds, greatly reducing the curing time. In addition, 5 hours of oven heating consumes a lot of electricity, while UV light lamp 71 curing only takes 20-30 seconds, which helps to reduce energy consumption.

[0083] Optionally, in some other embodiments, step S1 further includes the following step:

[0084] S11: The feeding pusher in the feeding mechanism 61 of the dispensing machine pushes the LED light sheet in the material box to the transmission track mechanism 5. The feeding drive motor drives the feeding lifting frame to rise and fall along the Z-axis direction. The material box in the feeding lifting frame rises and falls synchronously, so that the feeding pusher conveys the LED light sheet to the transmission track mechanism 5 one by one. The transmission track mechanism 5 conveys each LED light sheet to the bottom of the dispensing machine 6 for the dispensing machine 6 to dispense the LED light sheet. The average dispensing time of the dispensing machine 6 for a single LED light sheet is 8 seconds to 10 seconds. The LED light sheets after dispensing are conveyed to the curing equipment in sequence under the action of the transmission track mechanism 5.

[0085] Step S2 also includes the following steps:

[0086] S21: The curing equipment includes a UV lamp 71, which provides ultraviolet light to irradiate the LED light sheet located on the transport track mechanism 5 for 20-30 seconds;

[0087] S22: The curing equipment includes a baking tunnel oven 73. The LED light sheet after irradiation is transferred to the baking material transfer mechanism in the baking tunnel oven 73 through the transfer track mechanism 5. The baking material transfer mechanism runs through the oven body so that the LED light sheet can be heated in the oven body for 3-10 minutes to further improve the quality of the light sheet.

[0088] Step S3 also includes the following steps:

[0089] S31: The stripping and inspection equipment includes an AOI inspection device 81 and a lead cutter 82. Under the action of the transmission track mechanism 5, the LED light sheet after baking and heating is transported to the stage. The light source in the AOI inspection device 81 illuminates the surface of the LED light sheet. The optical lens collects the light reflected from the surface of the LED light sheet and focuses it onto the image sensor. The image sensor can convert the light signal into a digital signal. Under the action of the image acquisition card, the digital signal is transmitted to the AOI computer. The AOI computer identifies and determines whether the quality of the LED light sheet is abnormal and controls the stripping mechanism to strip the abnormal light sheet. The remaining qualified LED light sheets are transported to the lead cutter 82 through the transmission track mechanism 5.

[0090] S32: The transmission track mechanism 5 transmits the LED light sheet to the feeding mechanism in the lead cutting machine 82. The LED light sheet is transmitted to the cutting table through the feeding mechanism. The limiting cutting mechanism restricts the position of the LED light sheet on the cutting table. The cutting control host controls the cutting mechanism to cut the LED light sheet into a single finished LED bead.

[0091] Furthermore, compared to the traditional method of applying epoxy or silicone adhesive and then curing the LED sheet in an oven, which requires 5 hours of oven heating (including 1 hour at 80°C and 4 hours at 160°C), this invention uses UV adhesive for dispensing, followed by UV light irradiation with a UV lamp 71 and baking in a tunnel oven 73. From dispensing to curing, the time required is only 10-11 minutes, significantly shortening the curing time and effectively improving LED sheet production efficiency. In addition, 5 hours of oven heating consumes a large amount of electricity, while UV light irradiation with a UV lamp 71 only requires 20-30 seconds, and baking in the tunnel oven 73 only requires 3-10 minutes, reducing energy consumption and lowering energy costs in the production process.

[0092] Optionally, in some other embodiments, step S1 further includes the following step:

[0093] S11: The dispensing equipment includes a dispensing machine feeding mechanism 61. The feeding push rod in the dispensing machine feeding mechanism 61 pushes the LED light sheet in the material box to the transmission track mechanism 5. The feeding drive motor drives the feeding lifting frame to rise and fall along the Z-axis direction. The material box in the feeding lifting frame rises and falls synchronously, so that the feeding push rod delivers the LED light sheet to the transmission track mechanism 5 one by one.

[0094] S12: The dispensing equipment includes a dispensing machine 6 and a transmission track mechanism 5 that transports each LED light sheet to be dispensed to the area below the dispensing machine 6, and the dispensing machine dispenses the adhesive onto the LED light sheet.

[0095] S13: The dispensing equipment includes a dispensing machine discharge mechanism 62. The dispensed LED light sheets are transported to the material box in the discharge lifting frame under the action of the transmission track mechanism 5. For each LED light sheet that enters the material box, the discharge drive motor drives the discharge lifting frame to rise one layer along the Z-axis direction, and the material box rises one layer along the Z-axis direction, so that the dispensed LED light sheets can enter the material box in sequence and be spaced apart along the Z-axis direction.

[0096] Step S2 also includes the following steps:

[0097] S21: The curing equipment includes several light-illuminating boxes 1 spaced apart along the Z-axis within the mounting frame 70. The material boxes in the discharge lifting frame are collected manually and placed on each light-illuminating box 1.

[0098] S211: The material box is placed inside the auxiliary lifting frame. The push rod 401 on the light box 1 pushes out towards the side of the curing part on the X-axis, thereby pushing the bottom LED light sheet in the material box towards the auxiliary conveyor belt 402. At this time, the auxiliary lifting motor drives the auxiliary lifting frame to descend one layer along the Z-axis, and the material box descends one layer, so that the push rod 401 can sequentially transport the LED light sheets in the material box to the auxiliary conveyor belt 402 one by one.

[0099] S212: The auxiliary conveyor belt 402 transports the LED light sheet to the base plate 411. When the LED light sheet is transported from the base plate 411 to the left between the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212, the first transverse top block mechanism 4131 rises along the Z-axis and moves along the Y-axis towards the left side of the second transmission mechanism 42. The second transverse top block mechanism 4132 does not rise along the Z-axis, thereby pushing the LED light sheet to move to the left side of the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. When the LED light sheet moves to the corresponding position, the limiting pin mechanism 422 rises along the Z-axis. The two adjacent limiting pin mechanisms 422 can restrict the movement of the LED light sheet.

[0100] When the LED light sheet is conveyed from the base plate 411 to the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 on the right, the second transverse top block mechanism 4132 rises along the Z-axis and moves along the Y-axis towards the second transmission mechanism 42 on the right. The first transverse top block mechanism 4131 does not rise along the Z-axis, thereby pushing the LED light sheet to move to the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 on the right. When the LED light sheet moves to the corresponding position, the limiting pin mechanism 422 rises along the Z-axis. The two adjacent limiting pin mechanisms 422 can restrict the movement of the LED light sheet.

[0101] When the LED light sheet is transported from the first base plate 411 to the second base plate 411 (the first base plate is closer to the placement part 2, and the second base plate is farther away from the placement part 2), the first longitudinal top block mechanism 4141 on the first base plate 411 rises along the Z-axis and moves along the X-axis closer to the base plate 411, while the second longitudinal top block mechanism 4142 does not rise along the Z-axis. The roller conveying bracket 415 rolls, cooperating with the electric roller 412, thereby transporting the LED light sheet from the first base plate 411 to the second base plate 411. At this time, the first longitudinal top block mechanism 4141 on the second base plate 411 does not rise along the Z-axis, while the second longitudinal top block mechanism 4142 rises along the Z-axis to restrict the movement of the LED light sheet.

[0102] S213: Irradiate the LED sheet with ultraviolet light source inside the light box 1 for 10-15 minutes;

[0103] S214: After the illumination ends, the limiting pin mechanism 422 descends along the Z-axis, and the LED light sheets return to the base plate 411 one by one under the action of the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. The electric roller 412 rotates in the opposite direction, and the LED light sheets return to the auxiliary conveyor belt 402.

[0104] When the LED light sheet on the second base plate 411 returns to the first base plate 411, the second longitudinal top block mechanism 4142 on the second base plate 411 rises along the Z-axis and moves along the X-axis towards the second base plate, while the first longitudinal top block mechanism 4141 does not rise along the Z-axis. The roller conveying bracket 415 on the second base plate 411 cooperates with the electric roller 412 to transport the LED light sheet on the second base plate 411 back to the first base plate 411.

[0105] S215: The auxiliary conveyor belt 402 rotates in the opposite direction, and the LED light sheets move one by one towards the material box. For each LED light sheet that enters the material box, the auxiliary lifting motor drives the auxiliary lifting frame to rise one layer along the Z-axis, and the material box rises one layer, so that the LED light sheets can enter the material box in sequence and be spaced apart along the Z-axis.

[0106] Step S3 also includes the following steps:

[0107] S31: The quality of LED light sheets in the material box is uniformly identified manually, and LED light sheets with abnormal quality are manually removed.

[0108] S32: The stripping and testing equipment includes a lead cutter 82. Normal quality LED light sheets are placed into the feeding mechanism of the lead cutter 82 by the operator. The LED light sheets are transferred to the cutting table through the feeding mechanism. The limiting cutting mechanism restricts the position of the LED light sheets on the cutting table. The cutting control host controls the cutting mechanism to cut the LED light sheets into single finished LED beads.

[0109] Furthermore, compared to the traditional method of applying epoxy or silicone adhesive and then curing the LED sheet in an oven, which requires 5 hours of oven curing (1 hour at 80°C and 4 hours at 160°C), this invention uses UV adhesive for application and then uses a light-curing box to light-cur the applied LED sheet. From application to curing, the entire process takes only about 15 minutes, significantly reducing the curing time. In addition, the 5-hour oven heating requires a large amount of electricity, and the light-curing box... 1. Irradiation curing only takes 10-15 minutes, which helps reduce energy consumption. Secondly, compared to the combination of dispensing machine 6 and UV light lamp 71, the dispensing machine 6 needs to coordinate with the UV light lamp illumination time because the LED light sheets are uniformly transported by the transmission track mechanism 5, so the average dispensing time for a single LED light sheet is 8-10 seconds. However, in this embodiment, the combination of dispensing machine 6 and light box 1 allows the dispensing machine 6 to shorten the dispensing time and improve dispensing efficiency because the dispensed LED light sheets are collected manually and placed on the light box 1.

[0110] Optionally, in some other embodiments, step S1 further includes the following step:

[0111] S11: The dispensing equipment includes a dispensing machine feeding mechanism 61. The feeding push rod in the dispensing machine feeding mechanism 61 pushes the LED light sheet in the material box to the transmission track mechanism 5. The feeding drive motor drives the feeding lifting frame to rise and fall along the Z-axis direction. The material box in the feeding lifting frame rises and falls synchronously, so that the feeding push rod delivers the LED light sheet to the transmission track mechanism 5 one by one.

[0112] S12: The dispensing equipment includes a dispensing machine 6 and a transmission track mechanism 5 that transports each LED light sheet to be dispensed to the area below the dispensing machine 6, and the dispensing machine dispenses the adhesive onto the LED light sheet.

[0113] S13: The dispensing equipment includes a dispensing machine discharge mechanism 62. The dispensed LED light sheets are transported to the material box in the discharge lifting frame under the action of the transmission track mechanism 5. For each LED light sheet that enters the material box, the discharge drive motor drives the discharge lifting frame to rise one layer along the Z-axis direction, and the material box rises one layer along the Z-axis direction, so that the dispensed LED light sheets can enter the material box in sequence and be spaced apart along the Z-axis direction.

[0114] Step S2 also includes the following steps:

[0115] S21: The curing equipment includes several light-illuminating boxes 1 spaced apart along the Z-axis within the mounting frame 70. The material boxes in the discharge lifting frame are collected manually and placed on each light-illuminating box 1.

[0116] S211: The material box is placed inside the auxiliary lifting frame. The push rod 401 on the light box 1 pushes out towards the side of the curing part on the X-axis, thereby pushing the bottom LED light sheet in the material box towards the auxiliary conveyor belt 402. At this time, the auxiliary lifting motor drives the auxiliary lifting frame to descend one layer along the Z-axis, and the material box descends one layer, so that the push rod 401 can sequentially transport the LED light sheets in the material box to the auxiliary conveyor belt 402 one by one.

[0117] S212: The auxiliary conveyor belt 402 transports the LED light sheet to the base plate 411. When the LED light sheet is transported from the base plate 411 to the left between the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212, the first transverse top block mechanism 4131 rises along the Z-axis and moves along the Y-axis towards the left side of the second transmission mechanism 42. The second transverse top block mechanism 4132 does not rise along the Z-axis, thereby pushing the LED light sheet to move to the left side of the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. When the LED light sheet moves to the corresponding position, the limiting pin mechanism 422 rises along the Z-axis. The two adjacent limiting pin mechanisms 422 can restrict the movement of the LED light sheet.

[0118] When the LED light sheet is conveyed from the base plate 411 to the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 on the right, the second transverse top block mechanism 4132 rises along the Z-axis and moves along the Y-axis towards the second transmission mechanism 42 on the right. The first transverse top block mechanism 4131 does not rise along the Z-axis, thereby pushing the LED light sheet to move to the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 on the right. When the LED light sheet moves to the corresponding position, the limiting pin mechanism 422 rises along the Z-axis. The two adjacent limiting pin mechanisms 422 can restrict the movement of the LED light sheet.

[0119] When the LED light sheet is transported from the first base plate 411 to the second base plate 411 (the first base plate 411 is closer to the placement part 2, and the second base plate 411 is farther away from the placement part 2), the first longitudinal top block mechanism 4141 on the first base plate 411 rises along the Z-axis and moves along the X-axis closer to the base plate 411, while the second longitudinal top block mechanism 4142 does not rise along the Z-axis. The roller conveying bracket 415 rolls, cooperating with the electric roller 412, thereby transporting the LED light sheet from the first base plate 411 to the second base plate 411. At this time, the first longitudinal top block mechanism 4141 on the second base plate 411 does not rise along the Z-axis, while the second longitudinal top block mechanism 4142 rises along the Z-axis to restrict the movement of the LED light sheet.

[0120] S213: Irradiate the LED sheet with ultraviolet light source inside the light box 1 for 10-15 minutes;

[0121] S214: After the illumination ends, the limiting pin mechanism 422 descends along the Z-axis, and the LED light sheets return to the base plate 411 one by one under the action of the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. The electric roller 412 rotates in the opposite direction, and the LED light sheets return to the auxiliary conveyor belt 402.

[0122] When the LED light sheet on the second base plate 411 returns to the first base plate 411, the second longitudinal top block mechanism 4142 on the second base plate 411 rises along the Z-axis and moves along the X-axis towards the second base plate, while the first longitudinal top block mechanism 4141 does not rise along the Z-axis. The roller conveying bracket 415 on the second base plate 411 cooperates with the electric roller 412 to transport the LED light sheet on the second base plate 411 back to the first base plate 411.

[0123] S215: The auxiliary conveyor belt 402 rotates in the opposite direction, and the LED light sheets move one by one towards the material box. For each LED light sheet that enters the material box, the auxiliary lifting motor drives the auxiliary lifting frame to rise one layer along the Z-axis, and the material box rises one layer, so that the LED light sheets can enter the material box in sequence and be spaced apart along the Z-axis.

[0124] Step S3 also includes the following steps:

[0125] S31: The stripping and inspection equipment includes an AOI inspection device 81 and a lead-cutting machine 82. The cured LED sheets are placed on the AOI inspection device 81 by the operator. The light source in the AOI inspection device 81 illuminates the surface of the LED sheets. The optical lens collects the light reflected from the surface of the LED sheets and focuses it onto the image sensor. The image sensor can convert the light signal into a digital signal. Under the action of the image acquisition card, the digital signal is transmitted to the AOI computer. The AOI computer identifies and determines whether the quality of the LED sheets is abnormal and controls the stripping mechanism to strip the abnormal sheets. The remaining qualified LED sheets are transferred to the lead-cutting machine 82 through the transmission track mechanism 5.

[0126] S32: The transmission track mechanism 5 transmits the LED light sheet to the feeding mechanism in the lead cutting machine 82. The LED light sheet is transmitted to the cutting table through the feeding mechanism. The limiting cutting mechanism restricts the position of the LED light sheet on the cutting table. The cutting control host controls the cutting mechanism to cut the LED light sheet into a single finished LED bead.

[0127] Optionally, in some other embodiments, step S1 further includes the following step:

[0128] S11: The dispensing equipment includes a dispensing machine feeding mechanism 61. The feeding push rod in the dispensing machine feeding mechanism 61 pushes the LED light sheet in the material box to the transmission track mechanism 5. The feeding drive motor drives the feeding lifting frame to rise and fall along the Z-axis direction. The material box in the feeding lifting frame rises and falls synchronously, so that the feeding push rod delivers the LED light sheet to the transmission track mechanism 5 one by one.

[0129] S12: The dispensing equipment includes a dispensing machine 6 and a transmission track mechanism 5 that transports each LED light sheet to be dispensed to the area below the dispensing machine 6, and the dispensing machine dispenses the adhesive onto the LED light sheet.

[0130] S13: The dispensing equipment includes a dispensing machine discharge mechanism 62. The dispensed LED light sheets are transported to the material box in the discharge lifting frame under the action of the transmission track mechanism 5. For each LED light sheet that enters the material box, the discharge drive motor drives the discharge lifting frame to rise one layer along the Z-axis direction, and the material box rises one layer along the Z-axis direction, so that the dispensed LED light sheets can enter the material box in sequence and be spaced apart along the Z-axis direction.

[0131] Step S2 also includes the following steps:

[0132] S21: The curing equipment includes several light-illuminating boxes 1 spaced apart along the Z-axis within the mounting frame 70. The material boxes in the discharge lifting frame are collected manually and placed on each light-illuminating box 1.

[0133] S211: The material box is placed inside the auxiliary lifting frame. The push rod 401 on the light box 1 pushes out towards the side of the curing part on the X-axis, thereby pushing the bottom LED light sheet in the material box towards the auxiliary conveyor belt 402. At this time, the auxiliary lifting motor drives the auxiliary lifting frame to descend one layer along the Z-axis, and the material box descends one layer, so that the push rod 401 can sequentially transport the LED light sheets in the material box to the auxiliary conveyor belt 402 one by one.

[0134] S212: The auxiliary conveyor belt 402 transports the LED light sheet to the base plate 411. When the LED light sheet is transported from the base plate 411 to the left between the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212, the first transverse top block mechanism 4131 rises along the Z-axis and moves along the Y-axis towards the left side of the second transmission mechanism 42. The second transverse top block mechanism 4132 does not rise along the Z-axis, thereby pushing the LED light sheet to move to the left side of the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. When the LED light sheet moves to the corresponding position, the limiting pin mechanism 422 rises along the Z-axis. The two adjacent limiting pin mechanisms 422 can restrict the movement of the LED light sheet.

[0135] When the LED light sheet is conveyed from the base plate 411 to the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 on the right, the second transverse top block mechanism 4132 rises along the Z-axis and moves along the Y-axis towards the second transmission mechanism 42 on the right. The first transverse top block mechanism 4131 does not rise along the Z-axis, thereby pushing the LED light sheet to move to the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212 on the right. When the LED light sheet moves to the corresponding position, the limiting pin mechanism 422 rises along the Z-axis. The two adjacent limiting pin mechanisms 422 can restrict the movement of the LED light sheet.

[0136] When the LED light sheet is transported from the first base plate 411 to the second base plate 411 (the first base plate 411 is closer to the placement part 2, and the second base plate 411 is farther away from the placement part 2), the first longitudinal top block mechanism 4141 on the first base plate 411 rises along the Z-axis and moves along the X-axis closer to the base plate 411, while the second longitudinal top block mechanism 4142 does not rise along the Z-axis. The roller conveying bracket 415 rolls, cooperating with the electric roller 412, thereby transporting the LED light sheet from the first base plate 411 to the second base plate 411. At this time, the first longitudinal top block mechanism 4141 on the second base plate 411 does not rise along the Z-axis, while the second longitudinal top block mechanism 4142 rises along the Z-axis to restrict the movement of the LED light sheet.

[0137] S213: Irradiate the LED light sheet with ultraviolet light source inside the light box 1 for 2-3 minutes;

[0138] S214: After the illumination ends, the limiting pin mechanism 422 descends along the Z-axis, and the LED light sheets return to the base plate 411 one by one under the action of the first conveyor belt mechanism 4211 and the second conveyor belt mechanism 4212. The electric roller 412 rotates in the opposite direction, and the LED light sheets return to the auxiliary conveyor belt 402.

[0139] When the LED light sheet on the second base plate 411 returns to the first base plate 411, the second longitudinal top block mechanism 4142 on the second base plate 411 rises along the Z-axis and moves along the X-axis towards the second base plate, while the first longitudinal top block mechanism 4141 does not rise along the Z-axis. The roller conveying bracket 415 on the second base plate 411 cooperates with the electric roller 412 to transport the LED light sheet on the second base plate 411 back to the first base plate 411.

[0140] S215: The auxiliary conveyor belt 402 rotates in the opposite direction, and the LED light sheets move one by one towards the material box. For each LED light sheet that enters the material box, the auxiliary lifting motor drives the auxiliary lifting frame to rise one layer along the Z-axis, and the material box rises one layer, so that the LED light sheets can enter the material box in sequence and be spaced apart along the Z-axis.

[0141] S22: The curing equipment includes a dehumidifying oven 72. After being exposed to light, the LED sheets are placed in the dehumidifying oven 72 for heating and baking. The LED sheets are baked at 160℃ for 0.5 hours. The baked LED sheets are then collected manually.

[0142] Step S3 also includes the following steps:

[0143] S31: The stripping and inspection equipment includes an AOI inspection device 81 and a lead-cutting machine 82. The cured LED sheets are placed on the AOI inspection device 81 by the operator. The light source in the AOI inspection device 81 illuminates the surface of the LED sheets. The optical lens collects the light reflected from the surface of the LED sheets and focuses it onto the image sensor. The image sensor can convert the light signal into a digital signal. Under the action of the image acquisition card, the digital signal is transmitted to the AOI computer. The AOI computer identifies and determines whether the quality of the LED sheets is abnormal and controls the stripping mechanism to strip the abnormal sheets. The remaining qualified LED sheets are transferred to the lead-cutting machine 82 through the transmission track mechanism 5.

[0144] S32: The transmission track mechanism 5 transmits the LED light sheet to the feeding mechanism in the lead cutting machine 82. The LED light sheet is transmitted to the cutting table through the feeding mechanism. The limiting cutting mechanism restricts the position of the LED light sheet on the cutting table. The cutting control host controls the cutting mechanism to cut the LED light sheet into a single finished LED bead.

[0145] Furthermore, compared to the traditional method of applying epoxy or silicone adhesive and then curing the LED sheet in an oven, which requires 5 hours of oven heating (including 1 hour at 80°C and 4 hours at 160°C), this invention uses UV adhesive for dispensing, followed by irradiation of the LED sheet in a light-irradiation box 1, and then 0.5 hours of baking in a dehumidifying oven 72 at 160°C. From dispensing to curing, the entire process takes only about 0.5 hours, significantly shortening the curing time and further improving the quality of the LED sheet. In addition, the 5-hour oven heating consumes a large amount of electricity, while the light-irradiation box 1 only requires 2-3 minutes of irradiation and the dehumidifying oven 72 only requires 0.5 hours of baking, thus reducing energy consumption.
