Description

Technical Field

[0001] The utility model relates to the technical field of lamp bead processing, in particular to an LED assembly device. Background Art

[0002] LED (light-emitting diode) plays an increasingly important role in modern daily life and is widely used in lighting, display screens, traffic signals and other fields. Due to its advantages such as high efficiency, energy saving, long life and small size, LED products have gradually replaced traditional light sources and become the first choice for lighting and display technology. In this context, the production and assembly quality of LED lamps is directly related to their performance and market competitiveness. Therefore, advanced LED assembly equipment plays a pivotal role in the industry.

[0003] In LED assembly equipment, the assembly process of lamp beads usually includes two key processes: pin bending and wiping the surface of the cover (the cover is set on the light-emitting chip). Pin bending is to facilitate the subsequent soldering of the lamp beads on the circuit board, while wiping the surface of the cover is to remove dust, oil and other pollutants on the surface of the cover to ensure the optical performance and output efficiency of the lamp beads. However, in current technology, these two processes are often carried out separately, that is, the pins are bent first, and then the surface of the cover is wiped, or the surface of the cover is wiped first, and then the pins are bent.

[0004] This separate operation has some disadvantages. First, separate operations will increase production steps and time, reducing production efficiency. Second, during the process of bending the pins and wiping the cover surface, the lamp beads may be contaminated again due to multiple operations and transfers, which will affect the cleaning effect and product quality. Finally, the separation of multiple processes can easily lead to the complication of equipment and increase the difficulty of maintenance, thereby increasing production costs. Utility Model Content

[0005] The main purpose of the utility model is to provide an LED assembly device, aiming to solve the problem of low production efficiency caused by the LED assembly device in the prior art that the pin bending process and the cover wiping process are performed separately.

[0010] In a possible implementation, the processing head is formed with a mounting hole, the mounting hole passes through the connecting arm and forms an opening on a side of the connecting arm facing the processing seat, and an elastic member is disposed in the mounting hole;

[0011] The cleaning member is movably disposed in the mounting hole, one end of the cleaning member is connected to the elastic member, and the other end of the cleaning member extends out through the opening.

A guide block is provided on the outer circumferential wall of the mounting portion, and the guide block can be slidably inserted into the spiral groove.

[0014] In a possible implementation manner, the wiping portion forms a groove on a side portion facing the processing seat, and the groove is used for the light-transmitting cover of the lamp bead to extend into.

[0015] In a possible implementation, each of the bending arms has a side wall portion close to the cleaning member, each of the side wall portions is provided with a limiting member, and two limiting members are respectively located on opposite sides of the cleaning member and respectively abut against the cleaning member;

[0016] Each of the limiting members can be elastically deformed in the diameter direction of the mounting hole and in a direction away from the cleaning member.

[0033] The utility model provides a LED assembly device.

[0034] In the embodiment of the present utility model, Figures 1 to 5 As shown, the LED assembly equipment includes a processing seat 1, a pin bending mechanism 2 and a cleaning member 3;

[0035] The processing seat 1 is used for placing the lamp beads 4, and avoidance spaces 11 are formed on opposite sides of the processing seat 1;

[0036] The pin bending mechanism 2 includes a processing head 21 and a driving member 22. The processing head 21 includes two bending arms 211 extending in parallel and connecting arms 212 respectively connected to the two bending arms 211. The connecting arms 212 are arranged on the top of the processing seat 1. The two bending arms 211 correspond to the two avoidance spaces 11 one by one. The driving member 22 is transmission-connected to the connecting arms 212. The driving member 22 is used to drive the connecting arms 212 to move in a direction close to or away from the processing seat 1. The bending arms 211 can move in the corresponding avoidance spaces 11; and

[0037] The cleaning member 3 is disposed on the connecting arm 212 , and at least a portion of the cleaning member 3 extends from the connecting arm 212 toward the side of the processing seat 1 , so as to wipe the light-transmitting cover 42 of the lamp bead 4 when the connecting arm 212 moves in a direction close to the processing seat 1 .

[0038] In the specific implementation process, the processing seat 1 is designed to be able to stably place the lamp bead 4, and the avoidance space 11 on both sides thereof can be realized by slotting or opening to provide sufficient space for movement. The processing head 21 in the pin bending mechanism 2 can be made of high-strength material. The driving member 22 can be an electric push rod, a cylinder or other suitable transmission device for realizing the precise movement of the connecting arm 212. The cleaning member 3 can be designed to have a structure with flexible bristles or a cleaning cloth so as to effectively wipe the light-transmitting cover 42 of the lamp bead 4 during movement.

[0039] The present invention can clean the light-transmitting cover 42 of the lamp bead 4 while bending the pin 41 of the lamp bead 4, thus realizing an integrated operation process. This design avoids the cumbersome process and inefficiency caused by the separate operations of bending the pin 41 and cleaning the light-transmitting cover 42 in the traditional process. The integrated operation reduces the number of transfers of the lamp bead 4 between the various processes and reduces the risk of secondary contamination caused by multiple transfers, thereby improving the cleanliness and overall quality of the product. Secondly, by performing the cleaning operation simultaneously during the bending process, it can be ensured that each lamp bead 4 can be kept clean during the assembly process, thereby improving the optical performance of the lamp bead 4 and preventing dust or oil on the light-transmitting cover 42 from affecting the light output effect. In addition, the integrated design also simplifies the equipment structure, reduces the number of equipment and occupied space on the production line, and reduces the difficulty of equipment maintenance and production costs.

[0040] The processing head 21 is formed with a mounting hole 213, which penetrates the connecting arm 212 and forms an opening 212a on the side of the connecting arm 212 facing the processing seat 1, and an elastic member 214 is disposed in the mounting hole 213;

[0041] The cleaning member 3 is movably disposed in the mounting hole 213 , one end of the cleaning member 3 is connected to the elastic member 214 , and the other end of the cleaning member 3 extends out through the opening 212 a .

[0042] In actual implementation, the mounting hole 213 can be designed to be cylindrical or other suitable shapes. The elastic member 214 can be an elastic element such as a compression spring, an elastic washer, etc. One end of the cleaning member 3 is fixed on the elastic member 214, and the other end extends through the opening 212a to form a cleaning portion. This design allows the cleaning member 3 to move freely along the axial direction of the mounting hole 213, and always maintain a certain elastic pressure under the action of the elastic member 214, ensuring that the cleaning member 3 can closely fit the surface of the light-transmitting cover 42 of the lamp bead 4 for wiping.

[0043] The cleaning member 3 includes a mounting portion 31 and a wiping portion 32. The mounting portion 31 is connected to the elastic member 214. Part of the mounting portion 31 extends through the opening 212a and is connected to the wiping portion 32. The mounting portion 31 is made of a hard material, and the wiping portion 32 is made of a flexible material.

[0044] In actual implementation, the mounting portion 31 can be made of hard materials such as metal or high-strength plastic to ensure that it can remain stable and not easily deformed under the pressure of the elastic member 214. The wiping portion 32 can be made of soft materials such as silicone, sponge or flexible rubber, which can fit the surface of the light-transmitting cover 42 during the cleaning process and effectively remove dust and dirt. After the mounting portion 31 extends through the opening 212a, it is connected to the wiping portion 32, and can be connected by bonding, snap-fitting or threaded connection to ensure that the two parts are tightly combined and not easy to fall off.

[0045] This embodiment brings multiple beneficial effects by dividing the cleaning member 3 into a mounting portion 31 and a wiping portion 32, and using hard materials and flexible materials respectively. First, the hard material of the mounting portion 31 ensures the stability of the cleaning member 3 in the mounting hole 213, and will not be deformed or moved due to the pressure of the elastic member 214, thereby ensuring the position accuracy of the cleaning member 3 during operation. Secondly, the flexible material of the wiping portion 32 can fit the surface of the light-transmitting cover 42 of the lamp bead 4 well, and can effectively remove dust, oil and other impurities on the surface during the cleaning process, ensuring that the optical performance of the lamp bead 4 is not affected. This combination design of hard and flexible materials not only ensures the structural strength of the cleaning member 3, but also improves the cleaning effect. In addition, the flexible material also has the function of protecting the surface of the light-transmitting cover 42 of the lamp bead 4, avoiding scratches or damage caused by too hard contact during the cleaning process, and extending the service life of the lamp bead 4. Through this design, the cleaning member 3 can not only provide stable and effective cleaning during operation, but also adapt to the light-transmitting cover 42 of the lamp bead 4 of different shapes and sizes, thereby improving the versatility and adaptability of the equipment.

[0046] A spiral groove (not shown) is provided on the inner circumferential wall of the mounting hole 213, and the spiral groove extends spirally along the inner circumferential wall of the mounting hole 213. A guide block (not shown) is provided on the outer circumferential wall of the mounting portion 31, and the guide block can be slidably inserted into the spiral groove.

[0047] In actual implementation, the spiral groove in the mounting hole 213 can be formed by precision machining to ensure that it extends uniformly along the inner peripheral wall. The guide block can be mounted on the outer peripheral wall of the mounting portion 31 of the cleaning member 3 by casting or machining. Through this cooperation, the cleaning member 3 can achieve a smooth spiral motion under the guidance of the spiral groove. During installation, the guide block of the cleaning member 3 is aligned with the spiral groove and inserted, so that it can move and rotate along the spiral groove under the action of the elastic member 214.

[0048] By providing a spiral groove in the mounting hole 213 and providing a guide block on the outer peripheral wall of the mounting portion 31 of the cleaning member 3, when the processing head 21 moves downward and presses against the lamp bead 4, the cleaning member 3 will move axially upward in the mounting hole 213, and at the same time, perform a spiral motion under the cooperation of the guide block and the spiral groove. The spiral motion enables the cleaning member 3 to cover a wider area when wiping the surface of the light-transmitting cover 42 of the lamp bead 4, providing a more comprehensive and uniform cleaning effect. Due to the path of the spiral motion, the cleaning member 3 can more effectively remove stubborn stains and fine dust, ensuring the cleanliness of the surface of the lamp bead 4. Secondly, the coordinated design of the spiral groove and the guide block makes the cleaning member 3 have higher stability during the cleaning process, avoiding the problems of offset and uneven cleaning that may be caused by simple axial movement. Through this design, the cleaning member 3 can be close to the surface of the lamp bead 4 under the action of the elastic member 214, and combined with the effect of the spiral motion, the efficiency and effect of cleaning are further improved.

[0049] Of course, the design of the present application is not limited thereto, and in other embodiments, the guide block may be replaced with a thread, and the thread on the outer peripheral wall of the mounting portion 31 cooperates with the spiral groove to realize the spiral movement of the cleaning member 3.

[0050] A groove 321 is formed on the side of the wiping portion 32 facing the processing seat 1 , and the groove 321 is used for the light-transmitting cover 42 of the lamp bead 4 to extend into.

[0051] In actual implementation, the groove 321 of the wiping portion 32 can be customized according to the shape of the light-transmitting cover 42 of the lamp bead 4. For example, if the light-transmitting cover 42 of the lamp bead 4 is spherical, the groove 321 can be designed as a hemispherical shape; if the light-transmitting cover 42 is cylindrical, the groove 321 is designed as a cylindrical shape matching it.

[0052] The design of the groove 321 ensures that the wiping portion 32 can wrap the surface of the light-transmitting cover 42 of the lamp bead 4, providing all-round cleaning. This close fit can not only effectively remove dust, oil and other pollutants on the surface of the light-transmitting cover 42, but also avoid the problem of optical performance degradation caused by insufficient cleaning.

[0053] Each bending arm 211 has a side wall portion 211a close to the cleaning member 3, and each side wall portion 211a is provided with a limiting member 23. The two limiting members 23 are respectively located at two opposite sides of the cleaning member 3 and respectively abut against the cleaning member 3.

[0054] Each of the limiting members 23 can be elastically deformed in the diameter direction of the mounting hole 213 and in a direction away from the cleaning member 3 .

[0055] In actual implementation, in some embodiments, the limit member 23 can be made of an elastic material, such as spring steel, rubber, etc., which can undergo elastic deformation when subjected to pressure. At the same time, the limit member 23 can be fixed to the side wall portion 211a by means of screws or snaps, and its position and direction design must ensure that it can provide appropriate limiting and buffering effects when the cleaning member 3 moves.

[0056] By providing a limiter 23 on the side wall portion 211a of the bending arm 211 and enabling it to elastically deform in the diameter direction of the mounting hole 213, effective limiting and protection of the cleaning member 3 during its movement is achieved, and this design brings about significant technical effects. First, the limiter 23 provides a precise limiting function during the movement of the cleaning member 3, ensuring that the cleaning member 3 can move within a predetermined trajectory, avoiding uneven cleaning or damage to the wiping portion 32 due to offset. Secondly, the elastic deformation characteristics of the limiter 23 enable it to produce appropriate elastic deformation when subjected to excessive pressure, thereby playing a buffering and protective role, and preventing the cleaning member 3 or the lamp bead 4 from being damaged by excessive impact force.

[0057] The limiting member 23 includes an abutment arm 231, a rotating shaft 232 and a torsion spring (not shown in the figure), and the side wall portion 211a is formed with a mounting groove 211b. The abutment arm 231 and the groove wall of the mounting groove 211b are rotatably connected via the rotating shaft 232. Part of the structure of the abutment arm 231 extends out of the groove opening of the mounting groove 211b and abuts against the cleaning member 3. The torsion spring is sleeved on the rotating shaft 232, one end of the torsion spring is connected to the groove wall of the mounting groove 211b, and the other end of the torsion spring is connected to the abutment arm 231. The torsional deformation of the torsion spring can provide power for the abutment arm 231 to make the abutment arm 231 abut against the cleaning member 3.

[0058] In actual implementation, the abutment arm 231 can be made of high-strength metal material to ensure that it is not easily deformed when subjected to pressure, and the rotating shaft 232 can be connected between the mounting groove 211b and the abutment arm 231 through a bearing to ensure that it can rotate smoothly.

[0059] The abutment arm 231 is rotatably connected to the wall of the mounting groove 211b through the rotating shaft 232, so that it can produce adaptive adjustment when the cleaning member 3 moves, ensuring the limiting function while reducing the resistance to the cleaning member 3. The continuous elastic force provided by the torsion spring enables the abutment arm 231 to always maintain close contact with the cleaning member 3 during its movement, providing continuous limiting and buffering effects, avoiding uneven cleaning or equipment damage caused by vibration or displacement of the cleaning member 3. Secondly, the elastic properties of the torsion spring enable it to deform moderately when subjected to excessive pressure, providing effective buffering and protection, avoiding damage to the cleaning member 3 or the lamp bead 4 due to excessive impact force, and extending the service life of the equipment and the lamp bead 4.

[0060] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
