Description

Technical Field

[0001] This invention relates to the field of semiconductor technology, and in particular to an LED bracket stripping method, stripping equipment, and LED bracket. Background Technology

[0002] After the LED is encapsulated, the LED material needs to be detached from the entire support frame to form an individual LED bead. The entire support frame consists of the LED material and a connecting rib base that provides support and fixation. The connecting rib base is equipped with metal locking points for inserting into the plastic of the LED material to fix the LED material to the entire support frame.

[0003] See Figures 1 to 4 In existing LED support structures, the connecting rib base 1' typically has a "grid-shaped" structure, formed by multiple horizontal and vertical connecting ribs intersecting and connecting. When removing the LED material 2' from this type of support structure, a cutting blade is generally used to press the side edge with locking points 11' on the connecting rib base 1', causing the connecting ribs to deform and the side edge with locking points 11' to flip, thereby detaching the LED material 2' from the connecting rib base 1'.

[0004] In the process of removing the LED material 2' from the existing LED support, the relative movement direction of the LED material 2' and the metal clamping point 11' is opposite (e.g., Figure 1 If the LED material 2' moves downward relative to the metal locking point 11' and the metal locking point 11' moves upward relative to the LED material 2', it will damage the plastic 21', producing plastic 21' debris, which will contaminate the encapsulation environment. The plastic 21' debris is easy to stick to the LED adhesive surface, causing damage to the encapsulation adhesive surface, and in severe cases, it will cause the LED material 2' to fail. Summary of the Invention

S102. Connect the positioning part on the LED bracket to the corresponding force application part.

[0011] As an improvement to the above solution, step S3, expanding the spacing between two adjacent connecting units in the first direction to separate the LED material from the adjacent connecting units includes...

[0013] As an improvement to the above solution, each of the positioning pins is set in a different linear guide rail, and the extension direction of each linear guide rail is intersected with the first direction and the second direction. The spacing between the linear guide rails corresponding to the positioning pins in the same row changes monotonically along the second direction in the first direction.

[0014] As an improvement to the above solution, a support platform and a rotary drive mechanism are also included.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This invention discloses a method for removing LED bracket materials, see [link to relevant documentation]. Figures 5 to 15 The LED bracket includes a connecting rib base 1 and an LED material 2. The LED material 2 is disposed within a cavity enclosed by the connecting rib base 1, and the LED material 2 is connected to the connecting rib base 1 through opposite sides in a first direction. The LED material 2 is not connected to the connecting rib base 1 in other directions, meaning that when the LED material 2 is separated from the connecting rib base 1 on both opposite sides in the first direction, it can be unloaded. The unloading method includes the following steps: S1. Position the LED bracket at unloading station b; S2. Cut the connecting rib base 1 to form a plurality of connecting units a arranged along the first direction, so that each LED material 2 is connected to different connecting units a on opposite sides along the first direction. S3. Expand the distance between two adjacent connecting units a in the first direction to separate the LED material 2 from the adjacent connecting unit a.

[0022] In this embodiment, the connecting rib base 1 of the entire LED bracket is cut to form several connecting units a arranged along the first direction. Each LED material 2 is connected to different connecting units a on opposite sides along the first direction. By further expanding the distance between two adjacent connecting units a in the first direction, the LED material 2 is separated from the connecting units a connected to both sides, thus achieving material removal. During the material removal process, the connection between the LED material 2 and the connecting rib base 1 is not squeezed, that is, the plastic on the LED material 2 is not squeezed during the material removal process, avoiding damage to the plastic at the edge of the LED material 2 and generating debris. This further avoids contaminating the encapsulation environment, causing damage to the adhesive surface, or even failure of the entire LED material 2.

[0023] Preferably, the first direction in this embodiment is the horizontal direction. When the distance between two adjacent connecting units a expands in the first direction, and the LED material 2 separates from the connecting rib base 1 on both sides of the first direction, the LED material 2 is not interfered with and falls from the horizontal plane where the connecting rib base 1 is located by its own gravity.

[0024] Preferably, the LED bracket has positioning parts at both ends of each connecting unit a along the second direction. The second direction intersects the first direction, is preferably perpendicular, and is also horizontal. The unloading station b is provided with a force-applying part corresponding to the positioning part. This force-applying part can be the positioning pin 3 mentioned below, or a clamping structure that clamps the positioning part. The LED material 2 can be detached by driving each connecting unit a away along the first direction through a drive mechanism connected to the clamping structure. Step S1, positioning the LED bracket at the unloading station b, specifically includes: S101. Arrange linear guide rails 4 (or linear guide grooves) corresponding to the force-applying part, such that the initial end spacing of each linear guide rail 4 in the first direction is equal to the spacing of each positioning part on the LED bracket in the first direction, and the end spacing of each linear guide rail 4 in the first direction is greater than the spacing of each positioning part on the LED bracket in the first direction, and arrange the force-applying part at the initial end of the corresponding linear guide rail 4. S102. Connect the positioning part on the LED bracket to the corresponding force application part.

[0025] In step S2, the connecting rib base 1 is cut to form a plurality of connecting units a arranged along the first direction, that is, the two adjacent positioning parts in the first direction are cut off, so that each of the two ends of the formed connecting unit a in the second direction is provided with a positioning part. The connecting unit a can be moved by the force application part connected to the positioning part.

[0026] Since the LED material 2 is set in the cavity formed by the connecting rib base 1, when the connecting rib base 1 is cut to form a plurality of connecting units a arranged along the first direction in this embodiment, each column of LED material 2 arranged along the second direction should correspond to at least two cutting positions.

[0027] Based on this, step S3, expanding the distance between two adjacent connecting units a in the first direction to separate the LED material 2 from the adjacent connecting unit a, specifically includes: S301. Push each of the force-applying parts along the corresponding linear guide rail 4 to the end of the linear guide rail 4, so that the LED material 2 falls off the adjacent connecting unit a. S302, Move each of the force-applying parts along the corresponding linear guide rail 4 to the initial end of the linear guide rail 4.

[0028] Since each force-applying part is correspondingly set on the linear guide rail 4, when each force-applying part is synchronously pushed from the initial end of the linear guide rail 4 to the end of the linear guide rail 4, the distance between two adjacent force-applying parts in the first direction will gradually increase. The force-applying part drives the positioning part to move, and the distance between each connecting unit a in the first direction will also increase. That is, the distance between the connecting unit a in the first direction is expanded, and the LED material 2 is separated from the connecting unit a connected on both sides, thus realizing material removal.

[0029] In some embodiments, the unloading station b is provided with a support platform 5. The LED bracket has positioning portions at opposite ends of each connecting unit a along a second direction, the second direction intersecting the first direction, preferably perpendicularly, and the second direction is also horizontal. The unloading station b is provided with a force-applying portion corresponding to the positioning portion. The unloading method includes the following steps: S1. Position the LED bracket at the unloading station b; specifically including... S101. Arrange linear guide rails 4 corresponding to the force-applying part, such that the initial end spacing of each linear guide rail 4 in the first direction is equal to the spacing of each positioning part on the LED bracket in the first direction, and the end spacing of each linear guide rail 4 in the first direction is greater than the spacing of each positioning part on the LED bracket in the first direction, and arrange the force-applying part at the initial end of the corresponding linear guide rail 4. S102. Connect the positioning part on the LED bracket to the corresponding force application part.

[0030] S2. Cut the connecting rib base 1 to form a plurality of connecting units a arranged along the first direction, so that each LED material 2 is connected to different connecting units a on opposite sides along the first direction. In step S2, the connecting rib base 1 is cut to form a plurality of connecting units a arranged along the first direction, that is, the two adjacent positioning parts in the first direction are cut off, so that each of the two ends of the formed connecting unit a in the second direction is provided with a positioning part. The connecting unit a can be moved by the force application part connected to the positioning part.

[0031] S3. Expand the distance between two adjacent connecting units a in the first direction, so that the LED material 2 is separated from the adjacent connecting unit a; specifically including S301. Push each of the force-applying parts along the corresponding linear guide rail 4 to the end of the linear guide rail 4, so that the LED material 2 falls off the adjacent connecting unit a. S302, Move each of the force-applying parts along the corresponding linear guide rail 4 to the initial end of the linear guide rail 4.

[0032] S4. Drive the support platform 5 to flip, so that the LED material 2, which has detached from the connecting rib base 1, falls from the support platform 5.

[0033] The linear guide rail 4 can be mounted on the support platform 5 or installed independently of the support platform 5. In addition to receiving the detached LED material 2, the support platform 5 can also support the LED bracket as needed, or horizontally limit the LED material 2 on the LED bracket to prevent the LED material 2 from shifting horizontally along with the connecting unit a, thereby ensuring 100% detachment of the LED material 2.

[0034] In addition, see Figure 16 The present invention discloses an embodiment of a stripping device for the above-mentioned LED bracket stripping method, which includes a cutting mechanism, a linear drive mechanism and positioning pins 3. The cutting mechanism is used to perform a cutting action between two adjacent positioning pins 3 in a first direction; the linear drive mechanism is used to drive each positioning pin 3 to move synchronously, so that any two adjacent positioning pins 3 move away from or closer to each other in the first direction.

[0035] The positioning pin 3 corresponds to the force application part mentioned above, and the connecting rib base 1 of the LED bracket is provided with a positioning hole 111 corresponding to the positioning pin 3. The positioning hole 111 corresponds to the positioning part mentioned above. By passing the positioning hole 111 on the connecting rib base 1 through the corresponding positioning pin 3, the LED bracket is positioned at the unloading station b.

[0036] In this embodiment, the cutting mechanism can be arranged with multiple punches 6 arranged along the first direction, and each punch 6 can simultaneously cut the connecting rib base 1 between adjacent positioning holes 111.

[0037] Since the LED material 2 is disposed within the cavity enclosed by the connecting rib base 1, in this embodiment, the positioning pins 3 are preferably arranged in at least two rows in the second direction, with the first direction and the second direction intersecting. Correspondingly, the LED bracket has positioning holes 111 at both ends of each connecting unit a along the second direction. In this embodiment, the cutting mechanism is arranged with two rows of punches 6, each row of punches 6 arranged along the first direction. Under the action of a driving mechanism such as a cylinder, the two rows of punches 6 cut the connecting rib base 1 at both ends in the second direction, and the two rows of punches 6 preferably operate synchronously to improve processing efficiency.

[0038] In this embodiment, each positioning pin 3 is respectively disposed within a different linear guide rail 4. Each linear guide rail 4 extends in different directions along a straight line, and the extension direction of each linear guide rail 4 intersects with both the first and second directions. Furthermore, the spacing between the linear guide rails 4 corresponding to the positioning pins 3 in the same row changes monotonically along the second direction in the first direction. That is, in this embodiment, each linear guide rail 4 arranged in the first direction extends in different directions, and the distance between any two adjacent linear guide rails 4 monotonically increases or decreases along the second direction. Figure 17 Push rods 7 are provided at both ends of the linear guide rail 4. The positioning pin 3 is pushed by one of the push rods 7, and the process of the distance between two adjacent positioning pins 3 along the first direction changing from L1 to L2 is monotonically increasing. The positioning pin 3 is pushed by the other push rod 7, and the process of the distance between two adjacent positioning pins 3 along the first direction changing from L2 to L1 is monotonically decreasing.

[0039] When the linear drive mechanism drives each of the positioning pins 3 to move synchronously within its respective linear guide rail 4, any two adjacent positioning pins 3 move away from or closer together along the first direction. The linear drive mechanism of this embodiment includes a push rod 7 and a drive mechanism, such as a cylinder, for providing thrust to the push rod 7 in the second direction. The push rod 7 can be arranged to extend along the first direction. The push rod 7 moves along the second direction due to the thrust in the second direction, thereby pushing each positioning pin 3 to move along its respective linear guide rail 4. While the positioning pin 3 is displaced in the second direction, it is also displaced in the first direction, increasing or decreasing the distance between adjacent positioning pins 3 in the first direction.

[0040] The push rod 7 can also be configured in multiple ways, each push rod 7 can be equipped with a separate drive mechanism, and the driving force direction of each drive mechanism is different, so as to minimize the angle between the driving force direction and the extension direction of the corresponding linear guide 4, which can make the driving of the positioning pin 3 smoother. Each push rod 7 preferably corresponds to at least two adjacent linear guides 4 to simplify the drive layout. The linear guides 4 are preferably arranged symmetrically in the first direction, and the positioning pins 3 in the two adjacent linear guides 4 on both sides of the center of symmetry are preferably driven by the same push rod 7, and each push rod 7 drives the positioning pin 3 in the corresponding linear guide 4 to move.

[0041] Preferably, a return spring 8 is provided inside the linear guide rail 4, see [reference]. Figure 18The return spring 8 is arranged along the extension direction of the linear guide rail 4. One end of the return spring 8 is fixed to the linear guide rail 4, and the other end is connected to the positioning pin 3 to drive the positioning pin 3 to reset. That is, when the positioning pin 3 is subjected to the force of the push rod 7, it moves from the initial end to the end of the linear guide rail 4, and the distance between two adjacent positioning pins 3 along the first direction changes from L1 to L2. At this time, the distance between adjacent positioning pins 3 in the first direction increases. When the positioning pin 3 is not subjected to the force of the push rod 7, and the return spring 8 is set at the initial end of the linear guide rail 4, a pulling force is applied to the positioning pin 3, which will drive the positioning pin 3 back to the initial end, and the distance between two adjacent positioning pins 3 along the first direction changes from L2 to L1. At this time, the distance between adjacent positioning pins 3 in the first direction decreases; or When the positioning pin 3 is subjected to the force of the push rod 7, it moves from the end of the linear guide rail 4 to the initial end. The distance between two adjacent positioning pins 3 along the first direction changes from L2 to L1. At this time, the distance between adjacent positioning pins 3 in the first direction decreases. When the positioning pin 3 is not subjected to the force of the push rod 7, and the return spring 8 is set at the end of the linear guide rail 4, it applies a pulling force to the positioning pin 3. The return spring 8 drives the positioning pin 3 back to the end. The distance between two adjacent positioning pins 3 along the first direction changes from L1 to L2. At this time, the distance between adjacent positioning pins 3 in the first direction increases.

[0042] Preferably, the unloading device further includes a support platform 5 and a rotary drive mechanism 9. The support platform 5 is located below the cutting mechanism, and the rotary drive mechanism 9 has a horizontally arranged shaft connected to the support platform 5 for driving the support platform 5 to rotate. The rotary drive mechanism 9 drives the support platform 5 to rotate, enabling the support platform 5 to receive the fallen LED material 2 or to pour the material. The rotary drive mechanism 9 includes a drive motor and a rotating shaft, which is connected to the support platform 5.

[0043] More preferably, the support platform 5 is provided with a limiting structure (not shown in the figure) corresponding to the LED material 2. The limiting structure is used to restrict the movement of the LED material 2 along the plane containing the connecting unit a in the first direction and the second direction. That is, the support platform 5 supports the LED bracket and horizontally limits the LED material 2 on the LED bracket, preventing the LED material 2 from moving horizontally with the connecting unit a, thus avoiding the situation where the LED material 2 moves with one of the connecting units a without falling off, thereby ensuring 100% detachment of the LED material 2.

[0044] In this embodiment, the support platform 5 of the unloading device is set at the unloading station b. An LED bracket inlet c is located above the unloading station b, and an LED material outlet d is located below the unloading station b. The LED bracket enters the unloading station b from the LED bracket inlet c via a conveyor belt, etc., with each positioning pin 3 in its initial position. That is, at this time, the spacing between each positioning pin 3 in the first direction is the smallest and equal to the spacing between each positioning hole 111 on the LED bracket in the first direction. Each positioning hole 111 of the LED bracket fits onto the corresponding positioning pin 3. The support platform 5 provides support for the entire LED bracket, realizing the loading of the LED bracket. When the punch 6 falls and cuts the connecting rib base 1 to form several connecting units a arranged along the first direction, the positioning pins 3 move along the linear guide 4 from the initial end to the end, realizing the expansion of the spacing in the first direction, and the LED material 2 falls off. At this time, the drive support platform 5 is flipped downwards, causing the LED material 2 to fall and exit from the LED material outlet d. The connecting unit a is further transferred and collected by a transfer robot. After the support platform 5 is rotated and reset to a horizontal state and the positioning pin 3 moves and resets to the initial end along the linear guide rail 4, the next LED bracket is processed.

[0045] Furthermore, this invention also discloses an embodiment of an LED bracket, particularly suitable for unloading using the aforementioned LED bracket unloading method and / or unloading using the aforementioned unloading equipment. Specifically, see [link to documentation]. Figures 8 to 10 The LED bracket in this embodiment includes a connecting rib base 1 and an LED body 2. The connecting rib base 1 includes a first connecting rib 11 and a second connecting rib 12. The first connecting rib 11 extends along a first direction, and the second connecting rib 12 extends along a second direction. The first direction and the second direction are intersected. The first connecting rib 11 and the second connecting rib 12 enclose and form a plurality of chambers arranged along the first direction. The LED body 2 is located in the chamber. The LED body 2 is connected to the second connecting rib 12 but not to the first connecting rib 11. That is, the LED body 2 is only connected to the second connecting rib 12. The positioning part is provided with a positioning hole 111 at the intersection of the first connecting rib 11 and the second connecting rib 12.

[0046] In this embodiment, each first connecting rib 11 of the connecting rib base 1 is arranged in two groups in the second direction, and the second connecting rib 12 is arranged in multiple groups along the first direction, so as to simplify the cutting of the first connecting rib 11 and the structural layout of the positioning hole 111 and the positioning pin 3.

[0047] Specifically, in this embodiment, the connecting rib base 1 is made of metal, while the LED material 2 has a cup made of plastic, and the LED chip inside the cup is encapsulated with encapsulating glue. The second connecting rib 12 of the connecting rib base 1 has a second protrusion 121, i.e., a metal locking point. This second protrusion 121 protrudes in a first direction and connects with a corresponding slot on the plastic cup, such as by overlapping or locking. Expanding the gap at this time will cause the LED material 2 to detach from the second protrusion 121. The second protrusion 121 is preferably wedge-shaped, with its cross-sectional area gradually decreasing towards the plastic cup to reduce the resistance to separation between the LED material 2 and the second protrusion 121.

[0048] Preferably, the average thickness of the second protrusion 121 does not exceed 1 / 3 of the thickness of the connecting rib base 1, and two adjacent second protrusions 121 are provided with a preset distance along the second direction, that is, the second protrusion 121 is relatively thin and has a broken line structure on the entire connecting rib base 1. The position where the second protrusion 121 is connected to the connecting rib base 1 is a weak point. Even if the second protrusion 121 is embedded in the LED material 2 and the connection between the two is relatively tight, the tension generated by the expansion gap will cause the LED material 2 together with the second protrusion 121 to be pulled off the connecting rib base 1, thereby achieving separation, improving the reliability of material removal, and the plastic cup on the LED material 2 is also not squeezed and no plastic debris is generated.

[0049] The first connecting rib 11 has a cutting portion 112 and a first protrusion 113. The width of the cutting portion 112 in the second direction (e.g., 0.3~0.5mm) is smaller than the width of the second connecting rib 12 in the first direction (e.g., 0.5~1mm), making it easier to cut the entire connecting rib base 1 into multiple connecting units a. The second connecting rib 12 also has better structural strength, and the expansion gap between the connecting units a is less prone to deformation under tension. The second connecting rib 12 is connected to the first protrusion 113, which protrudes in the second direction. The cross-sectional area of ​​the first protrusion 113 gradually decreases in the direction away from the cavity. The positioning portion is located on the first protrusion 113. When the positioning hole 111 of the positioning portion moves with the positioning pin 3 of the force-applying portion, causing the expansion gap between the connecting units a, the connecting units a are less prone to deformation, thereby avoiding the connecting units a from exerting torque on the LED material 2 and preventing the generation of plastic debris.

[0050] The LED bracket disclosed in this invention uses the LED bracket unloading equipment and method disclosed in this invention for unloading, which can completely avoid the generation of plastic debris and avoid the problems of plastic damage and contamination of the LED bracket surface.

[0051] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
