Description

Technical Field

[0001] The present invention belongs to the technical field of automated production of light-emitting devices, and in particular relates to a light-emitting device production method and equipment. Background Art

[0002] The conventional assembly process of LED lighting devices is as follows: first, the light-emitting panel is fixed to the base with screws, and then the lens plate is placed on the light-emitting panel and the lens plate and the base are fixed with screws. However, the above assembly method has the following problems:

[0003] 1. Installing the light-emitting board by manually screwing the screws requires operations such as hole alignment and screw tightening. This not only has low production efficiency but also high material and labor costs. Installing the light-emitting board requires 4 screws (material cost 0.11 yuan), screwing the screws takes 14 seconds, the labor cost is 0.15 yuan, and threading costs 0.6 yuan.

[0004] Second, the lens plate and the base are fixed with screws, which results in relatively low production efficiency. Furthermore, if the screws are screwed too tight, the lens may be crushed. If the screws are screwed too loose, the lens and the base may not fit together well. This makes it difficult to ensure the reliability of the waterproof, heat dissipation, and light distribution performance of the produced light-emitting device.

[0005] Third, in order to achieve waterproof sealing, a sealing ring is usually added between the lens and the base. However, the sealing ring is soft and easy to deform, and its size is difficult to control. At the same time, the installation of the solid sealing ring is difficult to achieve automated production.

This method can, on the one hand, save the material and labor costs of the traditional screw connection method, and on the other hand, enables the lens plate to cling to and squeeze the light-emitting plate under the action of the friction force generated by the interference fit, thereby improving the light distribution effect of the lens plate and the fit between the light-emitting plate and the base.

[0044] 2. The present invention achieves a double sealing effect by filling sealant at the insertion position of the lens plate and the base, and filling sealant in the sealing groove formed between the lens plate and the base, so that the produced light-emitting device has good waterproof and dustproof performance, and eliminates the use of solid sealing rings in the light-emitting device; the lens installation method with interference fit bypasses the two production nodes of screw installation and sealing ring installation that are extremely difficult to automate, thereby realizing fully automatic production of light-emitting devices at low cost.

[0045] 3. The present invention coordinates the front-end lifting conveyor, the workstation switching conveyor line, the end-end lifting conveyor and the return conveyor line. Without increasing the lateral width of the production equipment, the space below the workstation switching conveyor line is utilized to realize the automatic return of the positioning tooling of the light-emitting device, thereby further improving the production efficiency of the equipment.

[0046] 4. The present invention eliminates all manual nodes in the assembly process of the light-emitting device, realizes fully automatic production, and greatly improves the quality stability of the produced light-emitting device.

[0047] 5. The present invention completes the fixation between the lens plate, the light-emitting plate, and the base by pressing together, eliminating the manual screw-driving fixation method. The present invention sets an intermediate fastening structure based on interference fit between the lens plate and the base; the intermediate fastening structure can apply a fastening force to the middle position of the lens plate (i.e., the light-emitting area), on the one hand, to prevent the lens plate from bulging in the middle during long-term use, and on the other hand, the middle of the light-emitting plate is also subjected to squeezing force and pressed against the base, thereby improving the heat dissipation performance of the light-emitting device. At the same time, the intermediate fastening structure and the edge fastening structure are connected simultaneously in the same pressing operation, which has a high production efficiency.

[0048] 6. The present invention uses a special pressure piece to extrude the lens plate, so that only the middle fastening structure and the edge fastening structure on the lens plate are directly subjected to the extrusion force. This effectively avoids the light-emitting plate and the lens on the lens plate from being squeezed and damaged while achieving rapid installation of the lens plate by pressing.

[0079] The pressurizing and fastening mechanism 6 is used to press the lens plate 1 - 1 downwards so that an interference fit is formed between the lens plate 1 - 1 and the base 1 - 3 .

[0080] The second glue-spraying mechanism 7 is used to inject sealant into the sealing groove 1-6 formed between the outer side of the edge of the lens plate 1-1 of the light-emitting device 1 and the inner side of the edge of the base 1-3.

[0081] This embodiment provides a non-essential preferred technical feature: the base loading mechanism 2, the light-emitting plate loading mechanism 3 and the lens loading mechanism 5 all use industrial robots, and the workpiece loading is achieved by grasping and transferring; the structure of the industrial robot belongs to the existing technology and will not be described here.

[0082] This embodiment provides an optional preferred technical feature: the first glue applying mechanism 4 and the second glue applying mechanism 7 both use glue applying machines capable of injecting liquid sealant into the groove. The structure of the glue applying machine belongs to the prior art and will not be described in detail here.

[0083] This embodiment provides a non-essential preferred technical feature: the pressure-fastening mechanism 6 includes a press and a pressure member 6-1. The press is used to apply pressure downward, and its specific structure belongs to the prior art and will not be described in detail here. One or more pressure members 6-1 are fixed to the bottom of the pressing plate of the press for applying pressure. The number of pressure members 6-1 and the number of base placement positions 12-1 on the positioning tool 12 are both m; m≥1. The relative positions of the m pressure members 6-1 are consistent with the relative positions of the m base placement positions 12-1 on the positioning tool 12. When a positioning tool 12 reaches the preset position under the pressing plate of the press, the m pressure members 6-1 are respectively located directly above the m base placement positions 12-1.

[0084] This embodiment provides a non-essential preferred technical feature: the bottom of the pressure member 6-1 is convexly provided with an edge extrusion portion 6-1-1 and an intermediate extrusion portion 6-1-2. The edge extrusion portion 6-1-1 is annular, and its cross-sectional shape is the same as the top cross-sectional shape of the edge connector 1-4-1 on the lens plate 1-1 of the light-emitting device. The number of intermediate extrusion portions 6-1-2 and the number of interference fit units of the intermediate fastening structure 1-5 of the light-emitting device are both n; n ≥ 1. The positions of the n intermediate extrusion portions 6-1-2 relative to the edge extrusion portion 6-1-1 are consistent with the positions of the n interference fit units on the light-emitting device relative to the edge connector 1-4-1 on the light-emitting device. During the pressurization process, the edge extrusion portion 6-1-1 of the pressure member 6-1 presses against the edge of the lens plate of the light-emitting device (i.e., the position of the edge connector 1-4-1), and the n intermediate extrusion portions 6-1-2 of the pressure member 6-1 press against the tops of the n interference fit units on the lens plate of the light-emitting device. This prevents direct contact between the lens plate and the pressure element 6-1 in the area aligned with the light-emitting panel, thereby preventing damage to the light-emitting panel (particularly the light-emitting diodes on the light-emitting panel) during the pressing process. It should be noted that since the light-emitting panel has a positioning slot corresponding to the location of the interference fit unit, the location of the interference fit unit is not considered the area aligned with the light-emitting panel on the lens plate. Applying pressure to the location of the interference fit unit will not damage the light-emitting panel.

[0085] This embodiment provides a non-essential preferred technical feature: the workstation switching conveyor line 9 and the return conveyor line 11 have the same structure, and both use belt conveyors.

[0086] This embodiment provides a non-essential preferred technical feature: The workstation switching conveyor line 9 and the reflow conveyor line 11 have the same structure, each comprising a tooling conveyor unit or multiple tooling conveyor units connected in series. The tooling conveyor unit comprises a conveyor frame, a support plate, a drive shaft, a conveyor motor, a transmission assembly, and a tooling pusher. The workstation switching conveyor line 9 and the reflow conveyor line 11 share the same conveyor frame. A transmission assembly is mounted on each side of the conveyor frame. The transmission assembly comprises a drive belt and two drive wheels. The two drive wheels within the same transmission assembly are rotatably connected to the ends of the conveyor frame and connected by a drive belt. The drive wheels can be synchronous wheels or sprockets. If the drive wheels are synchronous wheels, the drive belt is a synchronous belt. If the drive wheels are sprockets, the drive belt is a chain. The two drive wheels at one end of the conveyor frame in the two transmission assemblies are coaxially arranged and secured by a drive shaft. The conveyor motor is secured to the conveyor frame, and its output shaft is secured to the end of the drive shaft. A horizontal support plate is secured to the conveyor frame. The support plate provides support for the positioning tooling 12. The support plate is provided with a long strip-shaped clearance groove along the conveying direction of the tooling conveying unit. A plurality of tooling pushers are installed between the two transmission components and are arranged at equal intervals along the movement direction of the transmission belt. The tooling pusher is in the shape of a long strip; the two ends of the tooling pusher are respectively fixed to the two transmission belts. A push block is fixed on the tooling pusher. The position of the push block is aligned with the clearance groove. When the tooling pusher is in the upper straight section of the transmission belt, the top of the push block on the tooling pusher is higher than the top surface of the support plate; as the transmission belt moves, the tooling pusher can push the positioning tooling 12 forward to realize the transportation of the light-emitting device.

[0087] This embodiment provides a non-essential preferred technical feature: the head-end lifting conveyor 8 and the end-end lifting conveyor 10 have the same structure, both including a lifting mechanism 8-1 and a transverse conveying mechanism 8-2. The transverse conveying mechanism 8-2 is mounted on the lifting mechanism 8-1. The lifting mechanism 8-1 drives the transverse conveying mechanism 8-2 to move up and down. The transverse conveying mechanism 8-2 has two vertical working positions: an upper working position and a lower working position. When the transverse conveying mechanism 8-2 is in the upper working position, it aligns with the workstation switching conveyor line 9. When the transverse conveying mechanism 8-2 is in the lower working position, it aligns with the return conveyor line 11. When the transverse conveying mechanism 8-2 is in the upper limit position, it can receive the positioning tool 12 output by the workstation switching conveyor line 9 or input the positioning tool 12 to the workstation switching conveyor line 9. When the transverse conveying mechanism 8-2 is in the lower limit position, it can input the positioning tool 12 to the return conveyor line 11 or receive the positioning tool 12 output by the return conveyor line 11.

[0088] This embodiment provides a non-essential preferred technical feature: the lateral conveying mechanism 8-2 utilizes a roller conveyor. The lifting mechanism 8-1 includes a lifting base frame 8-1-1, a lifting slide 8-1-2, a lifting sprocket, a lifting chain, and a lifting motor. Two lifting sprockets arranged vertically are rotatably connected to the lifting base frame 8-1-1 and connected by a lifting chain. The output shaft of the lifting motor is coaxially fixed to one of the lifting sprockets. The lifting slide 8-1-2 is slidably connected to the lifting base frame 8-1-1 and fixed to the lifting chain. The lateral conveying mechanism 8-2 is mounted on the lifting slide 8-1-2.

[0089] The working method of the light emitting device production equipment comprises the following steps:

[0090] Step 1: The base loading mechanism 2 grabs the base 1-3 of the light-emitting device and places it on the base placement position 12-1 of the positioning tool 12 at the base loading station.

[0091] Step 2. The positioning tool 12 equipped with the base 1-3 is moved from the base loading station to the light-emitting panel loading station under the drive of the station switching conveyor line 9; the light-emitting panel loading mechanism 3 grabs the light-emitting panel 1-2 of the light-emitting device and places it on the base 1-3 on the positioning tool 12 at the light-emitting panel loading station, so that the positioning groove on the light-emitting panel is aligned with the middle slot on the base 1-3.

[0092] Step 3: The positioning fixture 12 equipped with the base 1-3 and the light-emitting panel 1-2 is moved from the light-emitting panel loading station to the first gluing station driven by the station switching conveyor line 9. The first gluing mechanism 4 injects liquid sealant into the edge slots 1-4-2 and / or the middle slots 1-5-2 of the base 1-3.

[0093] Step 4: The positioning fixture 12, equipped with the base 1-3 and light-emitting panel 1-2, moves from the first gluing station to the lens loading station driven by the station switching conveyor line 9. The lens loading mechanism 5 grabs the lens panel 1-1 of the light-emitting device and places it on the base 1-3 on the positioning fixture 12 at the lens loading station, so that the edge connector 1-4-1 on the lens panel 1-1 abuts the edge slot 1-4-2 on the base 1-3.

[0094] Step 5. The positioning fixture 12 equipped with the base 1-3, the light-emitting panel 1-2 and the lens panel 1-1 is moved from the lens loading station to the pressurizing and fastening station driven by the station switching conveyor line 9. The pressure plate on the pressurizing and fastening mechanism 6 moves downward, so that the pressurizing member 6-1 at the bottom of the pressure plate squeezes the lens panel 1-1, inserts the edge connector 1-4-1 on the lens panel 1-1 into the edge slot 1-4-2 on the base 1-3 and forms an interference fit, and inserts the intermediate connector 1-5-1 into the corresponding intermediate slot 1-5-2 and forms an interference fit. The extrusion force F applied by the pressurizing and fastening mechanism 6 is m·F0; F0 is the preset pressure for a single light-emitting device, and its value is 5000N~30000N, and the extrusion time is 1s~2s. The maximum pressure of the pressurizing and fastening mechanism 6 is greater than F.

[0095] Step 6: The positioning fixture 12, which holds the base 1-3, light-emitting panel 1-2, and lens panel 1-1, is moved from the pressurizing and tightening station to the second gluing station, driven by the station switching conveyor line 9. The second gluing mechanism 7 injects liquid sealant into the sealing groove 1-6 between the lens panel 1-1 and the base 1-3, completing the assembly of the light-emitting device.

[0096] Step 7: The positioning fixture 12 equipped with the assembled light-emitting device 1 is moved from the second gluing station to the terminal lifting conveyor 10 driven by the station switching conveyor line 9. The assembled light-emitting device on the positioning fixture 12 is removed by an automatic unloading mechanism or manually. The light-emitting device 1 can be removed from the second gluing station, the terminal lifting conveyor 10, or between the second gluing station and the terminal lifting conveyor 10.

[0097] Step 8: The terminal elevator conveyor 10 lowers the empty positioning tool 12 until it is aligned with the input end of the return conveyor line 11. The terminal elevator conveyor 10 delivers the empty positioning tool 12 to the return conveyor line 11 and then rises again to reset. The return conveyor line 11 transports the positioning tool 12 to the head-end elevator conveyor 8; the head-end elevator conveyor 8 returns the positioning tool 12 to the workstation switching conveyor line 9, achieving tool recycling.

[0098] This embodiment provides a preferred non-essential technical feature: Figure 7 、 8As shown in Figures 9 and 9, part or all of the interference fit units on the light-emitting device prepared in this embodiment also include a groove 1-5-3 provided on the lens plate 1-1, a positioning groove 1-5-4 provided on the light-emitting plate 2, and a boss 1-5-5 integrally formed on the mounting surface of the base 1-3. The groove 1-5-3 is an annular structure, specifically surrounding the intermediate connector 1-5-1. The intermediate slot 1-5-2 is provided at the center of the outer end face of the boss 1-5-5. Since the boss 1-5-5 protrudes outward on the mounting surface of the base 3, providing the intermediate slot 1-5-2 on the boss 1-5-5 helps to increase the depth of the intermediate slot 1-5-2 without thickening the base 3 as a whole, thereby improving the tightness between the intermediate connector 1-5-1 and the intermediate slot 1-5-2.

[0099] The shape of the outer side surface of the boss 1-5-5 corresponds to the shape of the outer wall of the groove 1-5-3; the shape of the positioning groove 1-5-4 on the light-emitting board 2 corresponds to the shape of the boss 1-5-5. The boss 1-5-5 can pass through the positioning groove 1-5-4 on the light-emitting board 1-2 and be inserted into the groove 1-5-3 on the base 3. The groove 1-5-3, the positioning groove 1-5-4 and the boss 1-5-5 cooperate to automatically position the base, the light-emitting board and the lens board during assembly; the boss 1-5-5 is constrained by the groove 1-5-3 and completes positioning in both the horizontal and vertical directions within the horizontal plane; and the light-emitting board 2 is constrained by the boss 1-5-5 through the positioning groove 1-5-4 and completes positioning in both the horizontal and vertical directions within the horizontal plane. Under the action of the boss 1-5-5, the light-emitting board loading mechanism can automatically realize the positioning of the light-emitting board after completing the loading of the light-emitting board.

[0102] In this embodiment, the tooling conveying mechanism includes a first tooling conveying unit 16, a dispensing conveying section 17, and a second tooling conveying unit 18. The structures of the first tooling conveying unit 16 and the second tooling conveying unit 18 are the same as those of the workpiece conveying mechanism described in Example 1.

[0104] The glue dispensing mechanism 13 is used to apply light-guiding glue to each lamp bead of the light-emitting board. After curing, the outer surface shape of the light-guiding glue on the outside of the lamp bead is consistent with the inner concave shape of the lens, so that the gap between the lamp bead and the corresponding lens in the light-emitting device is fully filled, thereby improving the light distribution effect of the light-emitting device.

[0105] The dispensing conveyor section 17 utilizes a belt conveyor. The first transfer mechanism 14 is used to grab the light-emitting device 1 at the output of the first tooling conveying unit 16 and place it at the input of the dispensing conveyor section 17. The second transfer mechanism 15 is used to grab the light-emitting device 1 at the output of the dispensing conveyor section 17, after the dispensing operation has been completed, and place it at the second tooling conveying unit 18.

[0106] The first transfer mechanism 14 and the second transfer mechanism 15 are both industrial robots, and their specific structures are not described in detail. The dispensing mechanism 13 is an existing dispensing machine, and its specific structure is not described in detail.

[0107] The working method of the light emitting device production equipment comprises the following steps:

[0108] Step 1: The base loading mechanism 2 grabs the base 1-3 of the light-emitting device and places it on the base placement position 12-1 of the positioning tool 12 at the base loading station.

[0109] Step 2: The positioning tool 12 equipped with the base 1-3 is moved from the base loading station to the light-emitting panel loading station under the drive of the first tool conveying unit 16; the light-emitting panel loading mechanism 3 grabs the light-emitting panel 1-2 of the light-emitting device and places it on the base 1-3 on the positioning tool 12 at the light-emitting panel loading station, so that the positioning groove on the light-emitting panel is aligned with the middle slot on the base 1-3.

[0110] Step 3: The first transfer mechanism 14 grabs the base 1-3 with the light-emitting panel 1-2 mounted on the positioning fixture 12 at the output end of the first tooling conveying unit 16 and places it on the dispensing conveying section 17. After the positioning fixture 12 at the output end of the first tooling conveying unit 16 is empty, it is returned to the base loading station on the first tooling conveying unit 16 through the cooperation of the end-end lifting conveyor 10, the return conveyor line 11, and the head-end lifting conveyor 8 in the first tooling conveying unit 16.

[0111] Step 4: The base 1-3 with the light-emitting panel 1-2 is moved to the glue dispensing station driven by the glue dispensing conveying section 17. The glue dispensing mechanism 13 dispenses glue on each lamp bead of the light-emitting panel 1-2.

[0112] Step 5: The second transfer mechanism 15 grabs the base 1 - 3 at the output end of the dispensing conveying section 17 and places it on the positioning tool 12 at the input end of the second tool conveying unit 18 .

[0113] Step 6: The positioning tool 12 with the base 1-3 and the glued light-emitting board 1-2 is moved to the first glue-spraying station by the second tool conveying unit 18. The first glue-spraying mechanism 4 injects liquid sealant into the edge slots 1-4-2 and / or the middle slots 1-5-2 of the base 1-3.

[0114] Step 7: The positioning fixture 12, equipped with the base 1-3 and the light-emitting panel 1-2, is moved from the first gluing station to the lens loading station by the second fixture conveying unit 18. The lens loading mechanism 5 grabs the lens panel 1-1 of the light-emitting device and places it on the base 1-3 on the positioning fixture 12 at the lens loading station, so that the edge connector 1-4-1 on the lens panel 1-1 abuts against the edge slot 1-4-2 on the base 1-3.

[0115] Step 8. The positioning tool 12 equipped with the base 1-3, the light-emitting panel 1-2 and the lens panel 1-1 is moved from the lens loading station to the pressurizing and fastening station under the drive of the second tool conveying unit 18. The pressure plate on the pressurizing and fastening mechanism 6 moves downward, so that the pressurizing member 6-1 at the bottom of the pressure plate squeezes the lens panel 1-1, inserts the edge connector 1-4-1 on the lens panel 1-1 into the edge slot 1-4-2 on the base 1-3 and forms an interference fit, and inserts the intermediate connector 1-5-1 into the corresponding intermediate slot 1-5-2 and forms an interference fit. The extrusion force F applied by the pressurizing and fastening mechanism 6 is m·F0; F0 is the preset pressure for a single light-emitting device, and its value is 5000N to 30000N. The maximum pressure of the pressurizing and fastening mechanism 6 is greater than F.

[0116] Step 9: The positioning tool 12, which holds the base 1-3, light-emitting panel 1-2, and lens panel 1-1, is moved from the pressurizing and tightening station to the second gluing station by the second tool conveying unit 18. The second gluing mechanism 7 injects liquid sealant into the sealing groove 1-6 between the lens panel 1-1 and the base 1-3, completing the assembly of the light-emitting device.

[0117] Step 10. Remove the assembled light-emitting device 1; after the positioning tool 12 at the output end of the second tooling conveying unit 18 is empty, it is returned to the first gluing station on the second tooling conveying unit 18 through the cooperation of the end lifting conveyor 10, the return conveyor line 11 and the head-end lifting conveyor 8 in the second tooling conveying unit 18.

[0122] Step 3: Place the lens plate on the base so that the lens plate is aligned with the interference fit area on the base.

[0123] Step 4: Apply extrusion force to the lens plate to form an interference fit between the lens plate and the base.
