A blue and white LED bead dispensing device

Abstract

This invention relates to the field of LED lamp production, and more particularly to a blue-white LED bead dispensing device. This invention provides a blue-white LED bead dispensing device that can align the LED bases uniformly, enabling faster and more stable dispensing of LED beads. The blue-white LED bead dispensing device includes a base plate, a support, a mounting frame, and rotating shafts; the support is located on the side of the base plate, the mounting frame is fixedly connected to the top of the support, and two rotating shafts are rotatably connected to the mounting frame. A servo motor drives the conveyor belt to rotate, and the LED beads in the feeding trough fall sequentially into several grooves on the conveyor belt. The rotation of the conveyor belt causes the LED beads in the grooves to rotate, and the dispensing machine moves rapidly downwards to dispense glue sequentially onto the LED beads below the notch of the arc-shaped baffle. The arc-shaped baffle prevents the LED beads in the grooves of the conveyor belt from falling out, and also prevents the dispensing machine from splashing glue onto adjacent LED beads during its up-and-down movement, thereby enabling faster dispensing of the LED beads.

Description

Technical Field

[0001] This invention relates to the field of LED lamp manufacturing, and more particularly to a dispensing device for blue and white LED beads. Background Technology

[0002] LED lights refer to devices that can transmit, distribute, and modify the light distribution of LED light sources. This includes all components and parts necessary for fixing and protecting the LED light source, as well as the necessary wiring accessories for power connection. With their high efficiency, energy saving, long lifespan, and compact size, LED lights are becoming the mainstay product in the next-generation lighting market and are powerfully driving the rapid development of the environmental protection and energy-saving industry.

[0003] In the LED light production process, adhesive needs to be applied to the lamp bases to achieve a sealing effect. Currently, the adhesive application is done manually by moving the adhesive head of the adhesive dispensing machine to apply adhesive to each LED individually. Individual dispensing is inefficient and cannot continuously and quickly apply adhesive to LEDs. Furthermore, the current dispensing equipment does not fix the LEDs in place, making the dispensing process unstable. It is also difficult to align the LED bases consistently, which can easily lead to dispensing misalignment and affect the quality of the LED lights. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides a blue-white LED bead dispensing device that can align the lamp feet and dispense LED beads more quickly and stably.

[0005] Technical Solution: A blue-white LED bead dispensing device includes a base plate, a bracket, a mounting frame, a rotating shaft, gears, a toothed belt, a motor frame, a servo motor, a collection frame, a conveying device, and a dispensing device. The bracket is fixedly connected to the side of the base plate, and the mounting frame is fixedly connected to the top of the bracket. Two rotating shafts are rotatably connected to the mounting frame, and the two rotating shafts are symmetrically arranged. Gears are fixedly connected to both rotating shafts, and a toothed belt is wound between the two gears. Both gears mesh with the toothed belt. The motor frame is fixedly connected to the top of the bracket, and the servo motor is fixedly connected to the motor frame. The rotating shaft near the motor frame is fixedly connected to the output shaft of the servo motor. The collection frame is placed on the side of the base plate, the conveying device is located on the mounting frame and connected to the toothed belt, and the dispensing device is located on the mounting frame.

[0006] Furthermore, it is particularly preferred that the conveying device includes a conveyor belt, an arc-shaped baffle, a fixing frame, and a discharge chute. The conveyor belt is fixedly connected to the outside of the toothed belt and has several grooves. The arc-shaped baffle is disposed on the dispensing device and has a notch. The arc-shaped baffle is located outside the conveyor belt. The fixing frame is fixedly connected to the middle of the mounting frame. The discharge chute is fixedly connected to the fixing frame and is located directly above the conveyor belt. Limiting grooves are formed on both sides inside the discharge chute.

[0007] Furthermore, it is particularly preferred that the dispensing device includes a guide frame, an electric push rod, a slider, a connecting frame, and a dispensing machine. The guide frame is fixedly connected to the side of the mounting frame away from the servo motor. The guide frame is rotatably connected to a shaft away from the servo motor. The arc-shaped baffle is fixedly connected to the guide frame. The electric push rod is fixedly connected to the middle of the guide frame. The slider is fixedly connected to the telescopic rod of the electric push rod. The slider is slidably connected to the guide frame. The connecting frame is fixedly connected to the slider. The dispensing machine is fixedly connected to the connecting frame. The lower part of the dispensing machine is located in the notch of the arc-shaped baffle.

[0008] Furthermore, it is particularly preferred that a limiting device is also included, wherein a limiting device is provided between the two rotating shafts. The limiting device includes a fixed rod, a fixed seat, a rectangular plate, a movable block, a return spring, a limiting rod, and a torsion spring. The fixed rod is rotatably connected between the ends of the two rotating shafts away from the servo motor. The fixed seat is fixedly connected to the side of the fixed rod near the guide frame. The fixed seat is rotatably connected to the rotating shaft away from the servo motor. The rectangular plate is fixedly connected to the top of the fixed seat. The movable block is slidably connected to the rectangular plate. A return spring is connected between the rectangular plate and the movable block. A limiting rod is rotatably connected to both the rectangular plate and the movable block. A torsion spring is connected between the rectangular plate and the limiting rod. A torsion spring is also connected between the movable block and the limiting rod.

[0009] Furthermore, it is particularly preferred that the device also includes a slow-descent device mounted on the support. The slow-descent device includes a fixed shaft, a semi-circular disk, an arc-shaped magnet, and a rotating notched disk. The fixed shaft is fixedly connected to the upper middle side of the support. The semi-circular disk is fixedly connected to the end of the fixed shaft away from the support. The arc-shaped magnet is fixedly connected to the outside of the semi-circular disk. The rotating notched disk is rotatably connected to the outside of the arc-shaped magnet. The rotating notched disk has several slots and is located directly above the collection frame.

[0010] Furthermore, it is particularly preferred that the device also includes a misalignment device, which is disposed on the feeding trough. The misalignment device includes a misalignment shaft and a misalignment plate. Several misalignment shafts are rotatably connected to both sides of the feeding trough. The several misalignment shafts are arranged in a misaligned manner, and a misalignment plate is fixedly connected to each of the several misalignment shafts.

[0011] Furthermore, it is particularly preferred that the device also includes a partition device, which is disposed on the discharge trough. The partition device includes a partition shaft, a partition plate, and a drive wheel. Two partition shafts are rotatably connected to the lower part of the discharge trough. The two partition shafts are symmetrically arranged. A partition plate is fixedly connected to each of the two partition shafts. Both partition plates are located inside the discharge trough. A drive wheel is fixedly connected to one end of each of the two partition shafts.

[0012] Beneficial effects:

[0013] 1. The servo motor drives the conveyor belt to rotate, and the LED beads in the feeding trough will fall into several grooves of the conveyor belt in sequence. The rotation of the conveyor belt will drive the LED beads in the grooves to rotate. The dispensing machine moves quickly downward and dispenses glue to the LED beads below the notch of the arc baffle in sequence. The arc baffle will prevent the LED beads in the grooves of the conveyor belt from falling out, and at the same time prevent the dispensing machine from splashing glue onto the LED beads next to it during the up and down movement, so as to dispense the LED beads more quickly.

[0014] 2. When the LED beads in the groove of the conveyor belt move sequentially between the two limit rods, the inclined surfaces of the two limit rods will contact the LED beads and push them to rotate, allowing the LED beads' leads to pass through the gap between the two limit rods. This allows the LED beads' leads to be placed horizontally in sequence, preventing inconsistent placement of the LED beads' leads and affecting the dispensing quality. This facilitates more accurate dispensing by the dispensing machine. At the same time, the two limit rods can limit the LED beads during dispensing by the dispensing machine, making the dispensing of the LED beads more stable.

[0015] 3. When the LED beads after dispensing move to the end of the curved baffle, the curved magnet will sequentially attract the LED bead bases into one of the slots on the rotating notch disk. The rotation of the rotating notch disk will cause the LED beads in the slots to rotate. When the LED beads on the rotating notch disk rotate to the bottom of the semi-circular disk, the magnetic force of the curved magnet weakens. At this time, the LED beads located below the semi-circular disk will fall into the collection box. Since the rotating notch disk will cause the LED beads to rotate to a height closer to the collection box before falling, this can buffer the LED beads. At the same time, the rotation of the rotating notch disk will push the LED beads out of the groove of the conveyor belt, avoiding individual dispensing LED beads from sticking to the conveyor belt, causing secondary dispensing and affecting the dispensing quality of the LED beads.

[0016] 4. When the LED beads in the feeding trough move downwards under the action of gravity, they will push several misalignment plates to rotate. The misalignment plates will separate the LED beads in the feeding trough, preventing adjacent LED beads from rubbing against each other. At the same time, they will push the LED beads in the feeding trough downwards, preventing individual LED beads from getting stuck in the feeding trough and unable to move downwards. In this way, the LED beads in the feeding trough can fall into the groove of the conveyor belt more smoothly, realizing continuous dispensing.

[0017] 5. The rotation of the conveyor belt will push the partition closest to the servo motor to swing upward, which in turn will drive the partition farther away from the servo motor to swing upward. The upward swing of the two partitions together will push the LED light bead located at the bottom of the discharge trough to move upward a certain distance, separating the LED light bead located at the bottom of the discharge trough from the conveyor belt, so as to avoid the LED light bead located at the bottom of the discharge trough from contacting the conveyor belt, which would cause the LED light bead to rub against the LED light bead when the conveyor belt rotates, resulting in damage to the LED light bead.

[0031] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0032] Example 1

[0033] A blue-white LED bead dispensing device, such as Figures 1-6 As shown, the device includes a base plate 1, a bracket 2, a mounting frame 3, a rotating shaft 4, a gear 5, a toothed belt 6, a motor frame 7, a servo motor 8, a collection frame 81, a conveying device, and a dispensing device. The bracket 2 is bolted to the upper side of the base plate 1, and the mounting frame 3 is bolted to the top of the bracket 2. Two rotating shafts 4 are rotatably connected to the mounting frame 3. The two rotating shafts 4 are symmetrically arranged and horizontally positioned. Each of the two rotating shafts 4 is connected to a gear 5 via a flat key, and a toothed belt 6 is wound between the two gears 5. All 5 mesh with the toothed belt 6. The motor frame 7 is bolted to the top of the bracket 2. The servo motor 8 is bolted to the motor frame 7. The rotating shaft 4 near the motor frame 7 is fixedly connected to the output shaft of the servo motor 8. The collection frame 81 is placed on the upper side of the base plate 1. The collection frame 81 is used to collect the LED beads after dispensing. The conveying device is set on the mounting frame 3 and connected to the toothed belt 6. The conveying device is used to transport the LED beads. The dispensing device is set on the mounting frame 3. The dispensing device is used to dispense glue onto the LED beads.

[0034] The conveying device includes a conveyor belt 91, an arc-shaped baffle 92, a fixing frame 93, and a feeding trough 94. The conveyor belt 91 is fixedly connected to the outside of the toothed belt 6. The conveyor belt 91 has several grooves and is used to transport LED beads. The arc-shaped baffle 92 is mounted on the dispensing device and has a notch. The arc-shaped baffle 92 is located outside the conveyor belt 91 and is used to limit the LED beads on the conveyor belt 91. The fixing frame 93 is welded to the middle of the mounting frame 3. The feeding trough 94 is welded to the fixing frame 93 and is used to place LED beads. The feeding trough 94 is located directly above the conveyor belt 91, and has limiting grooves on both sides inside the feeding trough 94.

[0035] The dispensing device includes a guide frame 101, an electric push rod 102, a slider 103, a connecting frame 104, and a dispensing machine 105. The guide frame 101 is bolted to the side of the mounting frame 3 away from the servo motor 8. The guide frame 101 is rotatably connected to a rotating shaft 4 away from the servo motor 8. The arc-shaped baffle 92 is bolted to the guide frame 101. The electric push rod 102 is bolted to the middle of the guide frame 101 and is vertically arranged. The slider 103 is fixedly connected to the telescopic rod of the electric push rod 102 and is slidably connected to the guide frame 101. The connecting frame 104 is welded to the slider 103. The dispensing machine 105 is bolted to the connecting frame 104. The lower part of the dispensing machine 105 is located in the notch of the arc-shaped baffle 92. The dispensing machine 105 is used to dispense LED beads.

[0036] Initially, in actual operation, the LED beads to be glued are placed into the feeding trough 94 one by one. The limiting grooves on both sides of the feeding trough 94 limit the LED beads to be glued, preventing them from slipping off the feeding trough 94. Then, the servo motor 8 and the electric push rod 102 are started. The output shaft of the servo motor 8 rotates, which drives the rotating shaft 4 and gear 5 away from the guide frame 101 to rotate together. The rotation of gear 5 away from the guide frame 101 drives the rotating shaft 4 and gear 5 close to the guide frame 101 to rotate together through the toothed belt 6. The rotation of the toothed belt 6 drives the conveyor belt 91 to rotate, and the LED beads to be glued in the feeding trough 94 are then dispensed. The LED beads to be glued will fall sequentially into the grooves of the conveyor belt 91 under the influence of gravity. The rotation of the conveyor belt 91 will cause the LED beads to be glued in the grooves to rotate along the toothed belt 6. The arc-shaped baffle 92 will limit the LED beads to be glued in the grooves of the conveyor belt 91, preventing them from falling out. It also prevents the glue dispensing machine 105 from splashing glue onto the adjacent LED beads during its vertical movement. The rapid extension of the telescopic rod of the electric push rod 102 will cause the slider 103 to move upwards. The upward movement of the slider 103 will drive the connecting frame 104 and the dispensing... The glue dispenser 105 moves upwards together with the electric push rod 102. The rapid retraction of the telescopic rod of the electric push rod 102 causes the slider 103 to move downwards. The downward movement of the slider 103 causes the connecting frame 104 and the glue dispenser 105 to move downwards together. At this time, the LED bead to be glued, located in one of the grooves of the arc-shaped baffle 92, has moved below the notch in the arc-shaped baffle 92. The rapid downward movement of the glue dispenser 105 will dispense glue onto the LED bead below the notch in the arc-shaped baffle 92. Because the glue dispenser 105 moves at a relatively fast speed, the speed of the LED bead movement will not affect the glue dispensing speed of the glue dispenser 105. The notch at 92 can both limit the dispensing machine 105 and not affect the dispensing machine 105 to dispense the LED beads to be dispensed, thus continuously dispensing the LED beads. As the conveyor belt 91 continues to move, it will carry the dispensed LED beads to continue moving along the toothed belt 6. When the dispensed LED beads move to the end of the arc-shaped baffle 92, the arc-shaped baffle 92 no longer limits the dispensed LED beads. The dispensed LED beads will fall off the conveyor belt 91 under the action of gravity and fall into the collection frame 81, where the collection frame 81 collects the dispensed LED beads.

[0037] Example 2

[0038] Based on Example 1, such as Figures 6-7As shown, it also includes a limiting device. A limiting device is provided between the two rotating shafts 4. The limiting device is used to swing the lamp feet of the LED lamp beads and limit the LED lamp beads. The limiting device includes a fixed rod 111, a fixed seat 112, a rectangular plate 113, a movable block 114, a return spring 115, a limiting rod 116, and a torsion spring 117. The fixed rod 111 is rotatably connected between the ends of the two rotating shafts 4 away from the servo motor 8. The fixed seat 112 is welded to the side of the fixed rod 111 near the guide frame 101. The fixed seat 112 is rotatably connected to the rotating shaft 4 away from the servo motor 8. The rectangular plate 113 is bolted to the fixed seat 112. At the top of 12, the movable block 114 is slidably connected to the rectangular plate 113. A return spring 115 is connected between the rectangular plate 113 and the movable block 114. The return spring 115 is located inside the rectangular plate 113. Limiting rods 116 are rotatably connected to both the rectangular plate 113 and the movable block 114. The limiting rods 116 are used to swing the lamp feet of the LED beads and limit the LED beads. Both limiting rods 116 are horizontally arranged. A torsion spring 117 is connected between the rectangular plate 113 and the limiting rods 116. A torsion spring 117 is also connected between the movable block 114 and the limiting rods 116. The torsion spring 117 is sleeved on the limiting rods 116.

[0039] Because the LED beads to be glued rotate when they fall into the groove of the conveyor belt 91, the LED bead bases may be misaligned, affecting the glue dispensing quality. Therefore, it is necessary to uniformly align the LED bead bases to a horizontal position. When the LED bead to be glued moves between the two limit rods 116 in the groove of the conveyor belt 91, the inclined surfaces of the two limit rods 116 will contact the LED bead and push it to rotate, thereby aligning the LED bead bases to a horizontal position. If the LED bead bases are pressed against... The limiting rod 116 located above the rectangular plate 113 moves upward as the LED bead to be glued continues to move, pushing the limiting rod 116 above the rectangular plate 113 to swing upward. This causes the torsion spring 117 above the rectangular plate 113 to twist, and under the action of the torsion spring 117, the limiting rod 116 above the rectangular plate 113 swings downward, pushing the LED bead to be glued to rotate, allowing the LED bead's lead to pass through the gap between the two limiting rods 116. If the LED bead's lead blocks the limiting rod 116 below the rectangular plate 113, the LED bead to be glued continues to move. Continuing to move the LED will push the limiting rod 116 located below the rectangular plate 113 downwards, causing the torsion spring 117 located below the rectangular plate 113 to twist. Under the action of the torsion spring 117, the limiting rod 116 located below the rectangular plate 113 will swing upwards, pushing the LED bead to be glued to rotate, allowing the LED bead's lamp base to pass through the gap between the two limiting rods 116. This allows the LED bead's lamp base to be positioned horizontally in sequence, facilitating glue dispensing by the glue dispensing machine 105, while preventing the LED bead's lamp base from scratching the glue dispensing machine 105. The LED bead pushes one of the limiting rods... As the limit rod 116 swings, it pushes the limit rod 116 located below the rectangular plate 113 to move away from the material discharge trough 94. The movement of the limit rod 116 below the rectangular plate 113 will drive the movable block 114 to move away from the material discharge trough 94, and the reset spring 115 will be compressed. This can prevent the limit rod 116 from blocking the LED when the LED is moving, which would cause the LED base to be bent. When the LED base is placed in a horizontal position, the reset spring 115 will reset and drive the movable block 114 and the limit rod 116 located below the rectangular plate 113 to reset.

[0040] Example 3

[0041] Based on Example 2, such as Figures 8-9As shown, it also includes a slow-descent device, which is mounted on the bracket 2. The slow-descent device is used to buffer the LED beads and prevent individual LED beads that have been glued from sticking to the conveyor belt 91, causing secondary glue application. The slow-descent device includes a fixed shaft 121, a semi-circular disk 122, an arc-shaped magnet 123, and a rotating notch disk 124. The fixed shaft 121 is fixedly connected to the upper middle side of the bracket 2 and is horizontally arranged. The semi-circular disk 122 is connected to the end of the fixed shaft 121 away from the bracket 2 by a flat key. The arc-shaped magnet 123 is welded to the outside of the semi-circular disk 122. The rotating notch disk 124 is rotatably connected to the outside of the arc-shaped magnet 123. The rotating notch disk 124 is used to buffer the LED beads and push them out of the groove of the conveyor belt 91. The rotating notch disk 124 has several slots and is located directly above the collection frame 81.

[0042] When the conveyor belt 91 rotates and moves the LED beads that have been glued to the end of the arc-shaped baffle 92, the arc-shaped magnet 123 has a certain attraction force on the LED bead base. The arc-shaped magnet 123 will sequentially attract the LED bead base located at the end of the arc-shaped baffle 92 into one of the slots on the rotating notch disk 124. Therefore, when the arc-shaped baffle 92 no longer limits its position, the LED beads will not immediately fall off the groove of the conveyor belt 91. As the conveyor belt 91 continues to rotate, the LED beads attracted into the slot of the rotating notch disk 124 continue to move, causing the rotating notch disk 124 to rotate and sequentially disengage from the conveyor belt 91. The rotation of the rotating notch disk 124 will cause the LED beads that have disengaged from the conveyor belt 91 to rotate. Because the curved magnet 123 attracts the LED beads' bases, the LED beads on the rotating notch disk 124 will not fall off. When the LED beads on the rotating notch disk 124 rotate sequentially to below the semicircular disk 122, the magnetic force of the curved magnet 123 weakens. At this time, the LED beads located below the semicircular disk 122 will fall into the collection frame 81 under the action of gravity. Since the rotating notch disk 124 will drive the LED beads to rotate to a height closer to the collection frame 81 before falling, this can buffer the LED beads. At the same time, the rotation of the rotating notch disk 124 will push the LED beads out of the groove of the conveyor belt 91, avoiding individual LED beads that have been glued sticking to the conveyor belt 91, causing secondary glue dispensing and affecting the glue dispensing quality of the LED beads.

[0043] Example 4

[0044] Based on Example 3, such as Figures 10-12As shown, it also includes a misalignment device, which is installed on the feeding trough 94. The misalignment device is used to allow the LED beads in the feeding trough 94 to fall more smoothly into the groove of the conveyor belt 91 to achieve continuous dispensing. The misalignment device includes a misalignment shaft 131 and a misalignment plate 132. Several misalignment shafts 131 are rotatably connected to both sides of the feeding trough 94. The several misalignment shafts 131 are misaligned and horizontal. A misalignment plate 132 is fixedly connected to each of the several misalignment shafts 131. The misalignment plate 132 is used to push the LED beads in the feeding trough 94 to move downward.

[0045] Initially, as workers place the LED beads to be glued into the feeding trough 94 one by one, the LED beads move downwards along the limiting groove of the feeding trough 94 under the action of gravity. This pushes several misalignment shafts 131 and misalignment plates 132 to rotate together. At the same time, the misalignment plates 132 separate the LED beads to be glued in the feeding trough 94, preventing adjacent LED beads from rubbing against each other. When the LED bead at the bottom of the feeding trough 94 falls into one of the grooves of the conveyor belt 91, the LED bead in the feeding trough 94 will move downwards under the action of gravity, driving the misalignment shafts 131 and misalignment plates 132 to rotate together. The rotation of the misalignment plates 132 pushes the LED beads in the feeding trough 94 downwards, preventing individual LED beads from getting stuck in the feeding trough 94 and unable to move downwards. This allows the LED beads in the feeding trough 94 to fall more smoothly into the grooves of the conveyor belt 91, achieving continuous glue dispensing.

[0046] Example 5

[0047] Based on Example 4, such as Figures 10-12 As shown, it also includes a partition device, which is installed on the feeding trough 94. The partition device is used to separate the LED beads located at the bottom of the feeding trough 94 from the conveyor belt 91, so as to prevent the LED beads located at the bottom of the feeding trough 94 from contacting the conveyor belt 91, which would cause the LED beads to rub against the LED beads when the conveyor belt 91 rotates, resulting in damage to the LED beads. The partition device includes a partition shaft 141, a partition plate 142 and a drive wheel 143. Two partition shafts 141 are rotatably connected to the lower part of the feeding trough 94. The two partition shafts 141 are symmetrically arranged and horizontally arranged. A partition plate 142 is fixedly connected to each of the two partition shafts 141. Both partition plates 142 are located in the feeding trough 94. The partition plates 142 are used to isolate the LED beads from the conveyor belt 91. One end of each of the two partition shafts 141 is connected to the drive wheel 143 through a flat key.

[0048] Initially, the rotation of the conveyor belt 91 pushes the partition 142 near the servo motor 8 to swing upwards. This upward swing of the partition 142 near the servo motor 8 causes the partition shaft 141 and drive wheel 143 near the servo motor 8 to rotate together. The rotation of the drive wheel 143 near the servo motor 8 causes the drive wheel 143 away from the servo motor 8 and the partition shaft 141 to rotate together. The rotation of the partition shaft 141 away from the servo motor 8 causes the partition 142 away from the servo motor 8 to swing upwards. The upward swing of both partitions 142 together pushes the LED bead located at the bottom of the discharge chute 94 upwards a certain distance, thus moving the LED bead located at the bottom of the discharge chute 94. The LED beads at the bottom of the material trough 94 are isolated from the conveyor belt 91 to prevent them from contacting the conveyor belt 91 and causing the LED beads to rub against each other when the conveyor belt 91 rotates, which could damage the LED beads. When one of the grooves of the conveyor belt 91 rotates to be below the conveyor belt 91, the two partitions 142 swing downward under the force of gravity. The downward swing of the two partitions 142 will no longer limit the LED beads at the bottom of the material trough 94, and the LED beads at the bottom of the material trough 94 will fall onto one of the grooves of the conveyor belt 91 and be dispensed with glue as the conveyor belt 91 rotates.

The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
