Description

Technical Field

[0001] This invention relates to the field of LED packaging, and more specifically to a processing apparatus for LED packaging. Background Technology

[0002] Currently, when applying encapsulating adhesive to LED encapsulation covers, a dispensing method is commonly used. During dispensing, the LED board is first fixed, and then the dispensing head is manually controlled, resulting in low automation. Furthermore, manual dispensing relies on the operator's experience, leading to errors such as adhesive overflow and sticking. This not only affects the appearance of the LED board but also leaves a small amount of encapsulating adhesive adhering to the end of the LED encapsulation tube after each application. This small amount moves with the tube head, but to maintain a consistent amount of adhesive each time, the tube's discharge rate is kept consistent. As this small amount of adhesive continues to adhere to the lower end of the tube, it dries quickly due to insufficient dosage. This dried small amount of adhesive blocks the tube opening, affecting the discharge rate. Additionally, because the dried small amount adheres to the tube wall, subsequent applications will have excess encapsulating adhesive on the LED board, causing it to absorb any uncured encapsulating adhesive. This process can lead to greater errors, making it easier for encapsulating adhesive to overflow and stick, creating a vicious cycle.

[0003] In existing technologies, a robotic arm is typically used to move the adhesive tube. To address the aforementioned issues, the robotic arm moves to a cleaning mechanism after several dispensing cycles. The cleaning mechanism cleans the tube tip. However, this process is affected by the viscosity and flowability of the encapsulating adhesive. If the adhesive viscosity is too high and the flowability is too poor, the adhesive adhering to the tube tip will not be completely removed if the cleaning mechanism's working time is fixed. If the cleaning mechanism's working time is adjustable, the operator needs to adjust it according to the properties of the encapsulating adhesive before each production run. Furthermore, each cleaning cycle delays the robotic arm's working time; if the working time is too long, the cleaning time will significantly impact the work progress.

[0004] Therefore, it is necessary to design a processing device for LED packaging. Summary of the Invention

[0005] Therefore, it is necessary to provide a processing apparatus for LED packaging to address the problems of existing technologies.

[0006] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:

[0007] The processing apparatus for LED packaging includes a tubing connected to the output end of a robotic arm, and further includes:

[0008] The power mechanism, connected to the upper part of the hose, includes an assembly sleeve, an assembly motor, and two rotary drive mechanisms. The assembly sleeve is coaxially sleeved on the outside of the hose. The assembly motor is located at the upper end of the assembly sleeve. The two rotary drive mechanisms are symmetrically located at the lower end of the assembly sleeve. The assembly motor can drive the two rotary drive mechanisms to move circumferentially along the axis of the assembly sleeve.

[0009] Two cleaning mechanisms are connected to two rotary drive mechanisms respectively. They include two cylindrical extrusion pads. Several anti-slip grooves are formed at equal intervals on the outer edge of the extrusion pads. The extrusion pads can rotate along the outer wall of the tube head and also move back and forth in the vertical direction.

The sliding gear column is located below the cleaning gear and is keyed to the power long shaft. The power roller shaft is located on the side of the power long shaft away from the hose and is connected to the supporting shell through the support plate. The first driven gear is located beside the cleaning gear and is coaxially connected to the power roller shaft. The second driven gear is located below the first driven gear and is keyed to the power roller shaft. The second driven gear meshes with the sliding gear column.

[0014] Furthermore, the cleaning mechanism also includes a sliding disc and a limiting sleeve. The upper end of the sliding disc is formed with two limiting flanges, and the limiting sleeve is formed with a sliding flange. The two limiting flanges abut against the sliding flanges respectively. The sliding disc is rotatably connected to the upper end of the second driven gear, and the lower end of the first driven gear of the limiting sleeve is connected.

[0015] Furthermore, the middle end of the power roller shaft has two stepped flanges. The first driven gear is located at the upper end of the upper stepped flange. The cleaning mechanism also includes a supporting disc, a drive gear, a power gear, a first support plate, a second support plate, two drive pads, four limit slide rails, and four limit buckles. The drive gear is located below the second driven gear and is keyed to the power roller shaft. The power gear is located beside the drive gear and meshes with it. The power gear is coaxially rotatable with the long shaft of the power roller. The first support plate is located on the drive gear. The upper end of the wheel is rotatably connected to the power roller shaft via a bearing seat. The first support plate is also connected to the drive gear via a bearing seat. The second support plate is set on the upper end of the power gear and connected to the power gear via a bearing seat.

Four limit buckles are respectively slidably connected to the four limit slide rails. Four limit buckles are respectively fixedly connected to the outer wall of the support shell.

[0018] The beneficial effects of this invention compared to the prior art are:

[0019] Firstly, this device heats the encapsulating adhesive with a hot air blower, ensuring that the encapsulating adhesive remains liquid and is scraped off by a scraper, so that no dried encapsulating adhesive remains on the outer wall of the dispensing tube, reducing possible errors during dispensing.

[0020] Secondly, this device uses an assembly motor to drive two extrusion pads to clean the outer wall of the tubing. During cleaning, the extrusion pads can simultaneously perform three displacements: rotation along their own axis, revolution along the tubing axis, and reciprocating linear movement along the tubing axis. These three displacements of the extrusion pads ensure that no encapsulating adhesive remains on the outer wall of the tubing.

[0021] Thirdly, this device uses a combination of extrusion pads and scrapers to ensure that the outer wall of the tube is cleaned after each dispensing, preventing the dried encapsulating adhesive from interfering with the cleaning process due to prolonged lack of cleaning. Furthermore, this cleaning process can be performed while the robotic arm is moving, eliminating the need for additional cleaning time and improving work efficiency. Attached Figure Description

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] refer to Figures 1 to 8 A processing apparatus for LED packaging, comprising a tubing 53 connected to the output end of a robotic arm, characterized in that it further comprises:

[0034] The power mechanism 30 is connected to the upper part of the hose 53 and includes an assembly sleeve 35, an assembly motor 31, and two rotary drive mechanisms 39. The assembly sleeve 35 is coaxially sleeved on the outside of the hose 53. The assembly motor 31 is located at the upper end of the assembly sleeve 35. The two rotary drive mechanisms 39 are symmetrically located at the lower end of the assembly sleeve 35. The assembly motor 31 can drive the two rotary drive mechanisms 39 to move circumferentially along the axial direction of the assembly sleeve 35.

[0035] Two cleaning mechanisms 1 are connected to two rotary drive mechanisms 39 respectively. They include two cylindrical extrusion pads 2. Several anti-slip grooves 3 are formed at equal intervals on the outer edge of the extrusion pads 2. The extrusion pads 2 can rotate along the outer wall of the tube head of the tube 53 and can also move back and forth in the vertical direction. The anti-slip grooves 3 can increase the friction between the extrusion pads 2 and the tube head and scrape off the encapsulating adhesive.

[0036] Two recycling mechanisms 46 are respectively located on the sides of the two extrusion pads 2, including a scraper 47 and a hot air blower 48. The scraper 47 abuts against the outer edge of the extrusion pad 2 and can scrape off the encapsulating adhesive attached to the extrusion pad 2. The hot air blower 48 is located at the end of the scraper 47 away from the extrusion pad 2 and can heat the scraper 47 and the extrusion pad 2 so that the encapsulating adhesive can remain in a liquid state.

[0037] When this device is in operation, after the adhesive dripping from the tube 53 is complete, the assembly motor 31 starts and drives the two rotary drive mechanisms 39 to move in a circular motion along the axis of the assembly sleeve 35. During this process, the extrusion pads 2 connected to the two rotary drive mechanisms 39 reciprocate along the tube head axis. Simultaneously, the extrusion pads 2 rotate during this movement. During this process, the extrusion pads 2 abut against the tube wall of the tube 53 through several anti-slip grooves 3. Subsequently, under the action of the hot air blower 48, the encapsulating adhesive adhering to the tube wall of the tube 53 remains liquid. The scraper 47 scrapes away the encapsulating adhesive within the anti-slip grooves 3. It should be noted that, to ensure the encapsulating adhesive is completely removed, the two rotary drive mechanisms 39 also drive the two extrusion pads 2 to rotate along the circumference of the tube head, preventing any uncleaned dead corners from remaining on the tube head wall.

[0038] In order to enable the rotary drive mechanism 39 to move along the circumference of the hose 53, the following features are specifically provided:

[0039] The power mechanism 30 also includes a drive pin 32, an assembly gear 34, a magnetic gear 33, an integrated gear 36, a positioning gear ring 37, and a connecting bracket 38. The rotary drive mechanism 39 includes a connecting gear 40. The drive pin 32 is fixedly connected to the output end of the assembly motor 31. The assembly gear 34 is keyed to the lower end of the drive pin 32. The magnetic gear 33 is rotatably connected to the assembly sleeve 35 via a bracket. The assembly gear 34 meshes with the magnetic gear 33. The integrated gear 36 is located below the magnetic gear 33 and is rotatably connected to the outer wall of the hose 53. The positioning gear ring 37 is fixedly connected to the lower end of the assembly sleeve 35. The magnetic gear 33 can drive the integrated gear 36 to rotate through magnetic force. The connecting bracket 38 is coaxially fixedly connected to the upper end of the integrated gear 36. The connecting gear 40 is connected to the connecting bracket 38 via a pin. One side of the connecting gear 40 meshes with the integrated gear 36, and the other side meshes with the positioning gear ring 37. When the assembly motor 31 starts, it drives the assembly gear 34 to rotate via the drive pin 32. The rotation of the drive gear drives the magnetic gear 33, which in turn drives the integrated gear 36 to rotate via magnetic force. The rotation of the integrated gear 36 then drives the connecting bracket 38 to rotate. The rotation of the connecting bracket 38 causes the two connecting gears 40 connected to it to move along the circumference of the hose 53. During the movement of the two connecting gears 40, they also rotate on their own axis. As mentioned above, other parts in the rotary drive mechanism 39 also move along the circumference of the hose 53 along with the movement of the connecting gears 40.

[0040] In order to compensate for the drop on hose 53, the following features are specifically designed:

[0041] The rotary drive mechanism 39 also includes a connecting support plate 41, a first bevel gear 42, a second bevel gear 43, a third bevel gear 54, a fourth bevel gear 55, a first pulley 44, and a second pulley 45. The connecting support plate 41 is fixedly connected to one end of the connecting bracket 38 by a pin. The first bevel gear 42 is rotatably connected to the connecting bracket 38. The second bevel gear 43 is located beside the first bevel gear 42 and meshes with it. The first pulley 44 is coaxially connected to the second bevel gear 43. The second pulley 45 is located below the first pulley 44 and is connected to the first pulley 44 via a belt. The third bevel gear 54 is coaxially connected to the second pulley 45. The fourth bevel gear 55 is located beside the third bevel gear 54 and meshes with it. Because the hose 53 has a height difference between its upper and lower walls due to the stepped shaft, in order to compensate for this height difference so that the compression pad 2 can press against the lower wall of the hose 53, when the connecting bracket 38 rotates, the connecting bracket 38 will drive the connecting support plate 41 connected to it to move. The rotation of the connecting gear 40 will drive the first bevel gear 42 connected to it to rotate. The rotation of the first bevel gear 42 will drive the second bevel gear 43 meshing with it to rotate. The rotation of the second bevel gear 43 will drive the first pulley 44 connected to it to rotate. The rotation of the first pulley 44 will drive the second pulley 45 to rotate via the belt. The rotation of the second pulley 45 will drive the third bevel gear 54 connected to it to rotate. The rotation of the third bevel gear 54 will drive the fourth bevel gear 55 meshing with it to rotate.

[0042] In order to satisfy the rotation of the extrusion gasket 2, the following features are specifically designed:

[0043] The cleaning mechanism 1 also includes a supporting housing 8, a cleaning gear 4, a first driven gear 6, a second driven gear 7, a supporting housing 8, a sliding gear 5, a power roller shaft 10, and a power long shaft 12. The supporting housing 8 is fixedly connected to the lower end of the connecting support plate 41. The power long shaft 12 is rotatably connected to the supporting housing 8 through the support plate. The power long shaft 12 is coaxially connected to the fourth bevel gear 55. The cleaning gear 4 is located at the lower end of the fourth bevel gear 55 and is connected to the power long shaft 12. The sliding gear 5 is located below the cleaning gear 4 and is keyed to the power long shaft 12. The power roller shaft 10 is located on the side of the power long shaft 12 away from the hose 53 and is connected to the supporting housing 8 through the support plate. The first driven gear 6 is located beside the cleaning gear 4 and is coaxially arranged with the power roller shaft 10. The second driven gear 7 is located below the first driven gear 6 and is keyed to the power roller shaft 10. The second driven gear 7 meshes with the sliding gear 5. After the fourth bevel gear 55 rotates, it drives the clearing gear 4 and the sliding gear 5 to rotate via the power shaft 12. The rotation of the clearing gear 4 drives the first driven gear 6, which meshes with it, to rotate, while the rotation of the sliding gear 5 drives the second driven gear 7, which meshes with it, to rotate. The rotation of the second driven gear 7 drives the power roller shaft 10 to rotate. As mentioned above, the rotation of the power roller shaft 10 at this time can satisfy the rotation of the extrusion pad 2.

[0044] To enable movement of the power roller shaft 10, the following features are specifically provided:

[0045] The cleaning mechanism 1 also includes a sliding disk 13 and a limiting sleeve 15. The upper end of the sliding disk 13 is formed with two limiting flanges 14, and the limiting sleeve 15 is formed with a sliding flange 16. The two limiting flanges 14 abut against the sliding flange 16 respectively. The sliding disk 13 is rotatably connected to the upper end of the second driven gear 7, and the lower end of the first driven gear 6 of the limiting sleeve 15 is connected. When the power roller shaft 10 rotates, the rotation of the first driven gear 6 will drive the limit sleeve 15 connected to it to rotate. The rotation of the limit sleeve 15 will cause it to misalign with the two limit flanges 14 through the sliding flange 16. At this time, the sliding disk 13 will reciprocate along the axis of the sliding disk 13 due to the misalignment. During this process, the sliding disk 13 will drive the second driven gear 7 connected to it to move. The second driven gear 7 will drive the power roller shaft 10 connected to it to move. During this process, the second driven gear 7 will move along the teeth of the sliding gear column 5 to avoid affecting the movement of the power roller shaft 10.

[0046] To ensure stable movement of the compression pad 2, the following features are specifically provided:

[0047] The middle end of the power roller shaft 10 has two stepped flanges 11. The first driven gear 6 is located at the upper end of the stepped flange 11. The cleaning mechanism 1 also includes a supporting disc 20, a drive gear 18, a power gear 19, a first support plate 21, a second support plate 22, two drive pads 17, four limit slide rails 23, and four limit buckles 24. The drive gear 18 is located below the second driven gear 7 and is keyed to the power roller shaft 10. The power gear 19 is located beside the drive gear 18 and meshes with it. The power gear 19 is rotatably arranged coaxially with the power long shaft 12. The first support plate 21 is located on the drive gear... The upper end of the wheel 18 is rotatably connected to the power roller shaft 10 through a bearing seat. The first support plate 21 is also connected to the drive gear 18 through a bearing seat. The second support plate 22 is set at the upper end of the power gear 19 and is connected to the power gear 19 through a bearing seat. Two drive pads 17 are respectively set at the two ends of the first support plate 21 and the second support plate 22. Four limit slide rails 23 are respectively connected to the two drive pads 17. Four limit buckles 24 are respectively slidably connected to the four limit slide rails 23. The four limit buckles 24 are respectively fixedly connected to the outer wall of the support shell 8. The support disc 20 is coaxially connected to the power gear 19 and is keyed to the extrusion pad. When the power roller shaft 10 rotates, it drives the drive gear 18 connected to it to rotate. The rotation of the drive gear 18 drives the power gear 19 meshing with it to rotate. The power gear 19 drives the extrusion pad 2 to rotate through the support disc 20. In this process, in order to ensure that the drive gear 18 and the power gear 19 remain meshed at all times, thereby improving the stable movement of the extrusion pad 2, the first support plate 21 and the second support plate 22 can ensure that the power gear 19 and the drive gear 18 are always on the same horizontal plane, while the four limit slide rails 23 can ensure that the extrusion pad 2 will not move during the movement.

[0048] In order to enable the power roller shaft 10 to move and reset, the following features are specifically provided:

[0049] The clearing mechanism 1 also includes a supporting connecting plate 27, a connecting tension spring 28, two supporting sleeves 25, two anti-detachment short pins 26, and two connecting positioning pins 29. One end of each of the two anti-detachment short pins 26 extends into the two stepped flanges 11. One end of each of the two supporting sleeves 25 is rotatably connected to the other end of each of the two anti-detachment short pins 26. The supporting connecting plate 27 is fixedly connected to the other end of each of the two supporting sleeves 25. One end of each of the two anti-detachment short pins 26 is fixedly connected to both ends of the supporting connecting plate 27, and the other end is slidably connected to the supporting housing 8. The upper end of the connecting tension spring 28 is fixedly connected to the supporting housing 8, and the lower end is fixedly connected to the supporting connecting plate 27. When the power roller shaft 10 moves, in order to ensure that the power roller shaft 10 can be reset upward, the movement of the power roller shaft 10 will drive the two anti-detachment short pins 26 to move downward. The downward movement of the anti-detachment short pins 26 will drive the two support sleeves 25 connected to them to move downward. The downward movement of the support sleeves 25 will drive the support connecting plate 27 connected to them to move downward. The movement of the support connecting plate 27 will stretch the connecting spring 28. When the stretched connecting spring 28 resets, the power roller shaft 10 will also move upward to reset.

[0050] In order to collect the scraped-off encapsulating adhesive, the following features are specifically designed:

[0051] The recycling mechanism 46 also includes a recycling support cover 49, a collection guide plate 50, a recycling pin 51, and a recycling spring 52. The recycling support cover 49 is connected to the upper ends of the first support plate and the second support plate. The collection guide plate is connected to the lower end of the recycling support cover 49. One end of the scraper 47 abuts against the extrusion pad 2. One end of the recycling pin 51 is connected to the other end of the scraper 47. The other end of the recycling pin 51 is slidably connected to the recycling support cover 49. One end of the recycling spring 52 is connected to the scraper 47, and the other end is connected to the recycling support cover 49. The hot air blower 48 is connected to the side of the recycling support cover 49 away from the extrusion pad 2. When the extrusion gasket 2 is working, the hot air blower 48 can provide hot air. The hot air acts on the extrusion gasket 2 and the scraper 47 to keep the encapsulating adhesive in a liquid state. The scraper 47 can be pressed against the outer edge of the extrusion gasket 2 under the action of the recovery spring 52. As the extrusion gasket 2 rotates, the scraper 47 can scrape off the encapsulating adhesive scraped off in the anti-slip groove 3. The scraped-off liquid encapsulating adhesive can be collected by the collection guide cover.

[0052] The working principle of this device is as follows: after the glue tube 53 finishes dripping glue, the assembly motor 31 will start. At this time, the integrated gear 36 will rotate. After the integrated gear 36 rotates, it will drive the two connecting gears 40 to rotate along the circumference of the glue tube 53 through the connecting bracket 38. Subsequently, when the two connecting gears 40 revolve around the glue tube 53, they will also rotate on their own axis.

[0053] During this process, the rotation of the two connecting gears 40 causes the corresponding limiting sleeve 15 to rotate. When the limiting sleeve 15 rotates, it abuts against the limiting flange 14 through the sliding flange 16. At this time, the power roller shaft 10 will reciprocate vertically. Since the sliding disk 13 rotates during the movement, the power roller shaft 10 will rotate during the reciprocating movement. The rotation of the power roller shaft 10 will drive the power gear 19 to rotate through the drive gear 18. After the power gear 19 rotates, it will drive the extrusion pad 2 to rotate through the support disk 20. Finally, the extrusion pad 2 can abut against the tube wall of the tube 53 through several anti-slip grooves 3. Under the action of the hot air blower 48, the encapsulating adhesive attached to the tube wall of the tube 53 can remain in a liquid state. The scraper 47 can scrape off the encapsulating adhesive in the anti-slip grooves 3. The scraped encapsulating adhesive will fall into the collection guide plate 50 and be collected.

[0054] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
