Description

Technical Field

[0001] The invention belongs to the technical field of lens production, and in particular relates to a lens feeder. Background Art

[0002] Currently, LED light strips are mainly composed of PCB boards, lamp beads, and lenses. The lens needs to be attached to the PCB board using the SMT patch method to provide the necessary focusing performance for the lamp bead light source. It is an important component of the LED light strip.

[0003] Due to the large number of lenses in LED light strips and the high production demand, batch production and assembly operations are required. Conventional operations involve weaving lenses into tape one by one, which is then picked up by a placement machine and attached to the PCB. This production operation has high labor, time, and material costs, making it unsuitable for large-scale production of lenses. When using automated mechanisms for arrangement and transportation, the LED lens column array has inconsistent dimensions in length and width. To ensure precise alignment of the lenses during SMT placement operations, both the horizontal and vertical surfaces of the lens body are subject to strict directional alignment requirements. To achieve this requirement, it is often necessary to design a complex actuator structure, which is costly to develop, manufacture, and maintain. The actuator execution process also limits the production efficiency of the batch production line. Therefore, a new technical solution is needed to improve it. Summary of the Invention

[0006] Furthermore, an arrangement track is provided at the end of the linear track, and a gap is provided at the joint between the two. The middle part of the arrangement track is divided into multiple arrangement grooves corresponding to the linear grooves by a partition, and an induction light is provided above each arrangement groove.

[0007] Furthermore, the top plate is used to place multiple lenses, and the length a of the V-shaped groove wall in the cross-sectional direction, the arc length b of any point of the curved convex surface of the lens coinciding with the lens axis, and the diameter c of the bottom surface of the lens meet the following conditions: a>b>c; the bottom surface of the lens is provided with multiple column feet arranged in a rectangular array, and the length x of the rectangular array, the width y of the rectangular array, and the width z of the diversion track meet the following conditions: x>z>y.

[0008] Furthermore, the groove surface of the diverter groove connected to the head end of the V-shaped groove is higher than the top surface of the V-shaped groove, and the groove surface of the diverter groove connected to the tail end of the V-shaped groove is lower than the lowest point of the inner cavity of the V-shaped groove.

[0009] Furthermore, the tail end of the V-shaped groove is pointed, and among the groove walls on both sides of the V-shaped groove, the groove wall facing the outer side of the top plate is in contact with the side wall of the diversion groove.

[0010] Furthermore, the angle bisectors of the inner walls on both sides of the V-shaped groove are vertical lines, and the width of the V-shaped groove is smaller than the width of the falling hole.

Through the design of the V-groove shape and size, the embedded lens can be adjusted to a vertical state.

DETAILED DESCRIPTION

[0033] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] like Figure 1-2As shown, a lens feeder includes a top plate 10 and a vibration source 20, wherein the top plate 10 is arranged above the vibration source 20 and forms a vibration plate structure, a spiral track 11 is attached to the top plate 10, and the spiral track 11 extends from bottom to top in a spiral path, and at least one partition 11b is provided in the middle of the spiral track 11, and the extension track of the partition 11b forms an equidistant array with the extension track of the spiral track 11, and the partition 11b divides the inner groove of the spiral track 11 into a plurality of diversion grooves 11a, and the area outside the outer wall of the top plate 10 is taken as the outer side, and the bottom surface of each diversion groove 11a is sequentially provided with a V-shaped groove 11c and a drop hole 11d in the direction away from the center of the spiral track 11, the V-shaped groove 11c is a strip groove, and the drop hole 11d is a strip hole, and the extension tracks of the two form an equidistant array with the diversion groove 11a, On the axial cross-section where the central axis of the top plate 10 coincides, the walls of the V-shaped groove 11c clamp together to form a gradually opening from bottom to top. The V-shaped groove 11c fits against the outer wall of the diverter groove 11a. Oriented from the center of the top plate 10 to the outside, the track surface of the spiral track 11 forms an inclined surface in a direction away from the center of the top plate 10. The ends of the diverter grooves 11a extend beyond the ends of the V-shaped groove 11c and the drop holes 11d. Each diverter groove 11a is connected to a diverter track 11e, which is narrower than the diverter groove 11a. The two sides of the diverter tracks 11e are left empty, forming drop areas 11f. Each diverter track 11e is connected to a linear track 11g. The central portion of the linear track 11g is divided by a partition 11b into multiple linear grooves 11h corresponding to the diverter tracks 11e. The V-groove 11c serves as a structure to correct the lens conveying posture, ensuring that all lenses are uniformly arranged with their curved convex surfaces facing upward.

[0036] In this embodiment, an arrangement track 12 is provided at the end of the linear track 11g, and a gap is provided at the joint between the two. The middle part of the arrangement track 12 is divided into multiple arrangement slots 12a corresponding to the linear slots 11h by a partition 11b. An induction lamp 12b is provided above each arrangement slot 12a. Under the isolation setting of the gap, it is ensured that the dynamically transmitted lens material is pushed and collected in the static arrangement slot 12a, so that the static lens can be automatically or manually picked up.

[0037] In this embodiment, the top tray 10 is used to accommodate multiple lenses. The cross-sectional length a of the V-shaped groove 11c, the length b of the arc line coinciding with the lens axis at any point on the lens's curved convex surface, and the diameter c of the lens's bottom surface satisfy the following conditions: a>b>c. This ensures that the V-shaped groove 11c provides sufficient space for the lenses to tilt and roll. Therefore, whether the lens tilts with its bottom surface facing downward or rolls with its circular convex surface facing downward, the design of the groove wall dimensions of the V-shaped groove 11c ensures that the lens's tilting and rolling motions produce a sufficient tilting angle, allowing the lens to be smoothly inserted into the V-shaped groove 11c in a vertical position, further ensuring that the V-shaped groove 11c functions as a corrective lens transport posture.

[0038] At the same time, the bottom surface of the lens is provided with four column feet arranged in a rectangular array. The rectangular array length x, the rectangular array width y, and the diversion track 11e width z meet the following requirements: x>z>y. This ensures that the lens is smoothly embedded in the diversion track 11e within the gap space of the length of the rectangular array of its column feet, thereby screening irregular lenses transmitted in the width array direction, and further ensuring the consistency of the transmitted lens material on the horizontal plane.

[0039] In this embodiment, the width of the diverter groove 11a is greater than that of the diverter track 11e, and a guide groove 11i is provided at the connection portion between the diverter groove 11a and the diverter track 11e. From the diverter groove 11a to the diverter track 11e, the width of the guide groove 11i gradually shrinks from large to small, thereby ensuring that the conveying lens is smoothly incorporated into the entrance of the diverter track 11e.

[0040] The working principle of this embodiment is as follows:

[0041] S1: Place multiple lenses 30 in batches on the bottom of the top plate 10, start the vibration source 20 and drive the vibration plate to press Figure 4 As shown in the figure, the lens 30 is repeatedly thrown up and rises along the spiral track 11. At the same time, it is diverted to each diversion groove 11a under the action of the partition 11b. Since the track surface of the spiral track 11 is inclined from high to low toward the outside of the top plate 10, under the action of gravity and vibration, the lens 30 in each diversion groove 11a is gradually deflected and adhered to the outer groove wall of the diversion groove 11a for transmission, forming a Figure 3 In the state shown, when the lens 30 is placed in a natural horizontal position for vibration transmission, the V-shaped groove 11c is also in contact with the outer groove wall of the diverter groove 11a, so that when the lens 30 enters the head end of the V-shaped groove 11c, one end of the lens 30 loses support and flips sideways, and is embedded in the V-shaped groove 11c in a vertical position. When multiple lenses 30 are stacked, the stacked lens 30 falls due to the unstable support of the vertical lens 30 below it, and falls into the drop hole 11d next to the V-shaped groove 11c and is transmitted again. This avoids the chaotic stacking of the lenses 30 and ensures the orderly transmission of multiple lenses 30 one by one.

[0042] S2: If Figure 5 As shown, when the lens 30 is about to enter the head end of the V-shaped groove 11c with its bottom surface facing downward, the lens 30, which is transmitting vibration, adheres to the outer groove wall of the diverter groove 11a due to the inclined setting of the spiral track 11 and enters the track area where the V-shaped groove 11c is located; when the lens 30 has entered the head end of the V-shaped groove 11c, as shown Figure 6 As shown, at this time, the right end of the lens 30 is supported on the wall of the V-shaped groove 11c, and the left end of the lens 30 is in the empty area in the middle of the V-shaped groove 11c and loses support, causing the lens 30 to press Figure 7 As shown, the lens 30 rolls over to the left. The size of the V-shaped groove 11c is designed to make the length a of the groove wall of the V-shaped groove 11c greater than the diameter c of the bottom surface of the lens 30, which ensures that the lens 30 has a sufficient rollover angle and is embedded in the V-shaped groove 11c in a vertical posture. Figure 8 The vertical state shown (when the rollover angle is too large, you can enter the Figure 9 As shown in the state), the lens 30 is vibrated and transmitted at the same time. At this time, the arc convex surface on the left side of the lens body is against the oblique groove wall of the V-shaped groove 11c to form a stable support (the direction depends on the Figure 8 ), so that the lens 30 cannot be flipped toward the left, and there is a lack of stable support between the vertical surface on the right side of the lens 30 and the V-shaped groove 11c. Under the mechanical deviation caused by the continuous vibration transmission, the lens 30 tilts toward the right and its bottom surface adheres to the right groove wall of the V-shaped groove 11c, forming a Figure 9 As shown in the state, when reaching the end of the V-shaped groove 11c, as shown in the Figure 10 As shown, the lens 30 falls due to the loss of support from the right side wall of the V-shaped groove 11c, causing the bottom-down oblique lens 30 to fall back onto the groove surface of the diverter groove 11a, forming a bottom-down flat transmission posture;

[0043] like Figure 11 As shown in FIG. 1 , when the lens 30 enters the head end of the V-shaped groove 11c with the bottom surface facing upward, the arc convex surface of the lens 30 loses support and is in a suspended state. During the falling process, the arc convex surface of the lens 30 contacts the right side wall of the V-shaped groove 11c in advance, forming the following Figure 12 In the state shown, the arc convex surface of the lens 30 is pressed against the right side wall of the V-groove 11c, causing the lens 30 to roll toward the left. The size design of the V-groove 11c makes the length a of the V-groove 11c wall greater than the arc length b of the arc convex surface of the lens 30, so that the arc convex surface of the lens 30 adheres to the groove wall of the V-groove 11c and rolls away to generate a sufficient rollover angle, ensuring that the lens 30 can be smoothly embedded in the V-groove 11c in a vertical posture, forming a shape as shown in FIG. Figure 13 The state shown (when there is a roll margin, it is directly formed Figure 14 As shown in the state), at this time, the arc convex surface on the right side of the lens body is against the oblique groove wall of the V-shaped groove 11c to form a stable support (the direction depends on the Figure 13), so that the lens 30 cannot be flipped to the right, and there is a lack of stable support between the vertical surface on the left side of the lens 30 and the V-shaped groove 11c. Under the mechanical deviation caused by the continuous vibration transmission, the lens 30 tilts to the left and its bottom surface adheres to the left groove wall of the V-shaped groove 11c, forming a Figure 14 As shown in the state, when reaching the end of the V-shaped groove 11c, as shown in the Figure 15 As shown, the lens 30 falls due to the loss of support from the left side wall of the V-shaped groove 11c, causing the bottom-down oblique lens 30 to fall back onto the groove surface of the diverter groove 11a, forming a bottom-down flat transmission posture;

[0044] Through this step, the symmetrical arrangement of the V-shaped groove 11c can release the tilted lenses 30 to the groove surface of the tail diverter groove 11a, so that all lenses 30 are arranged in an indiscriminate state with the arc-shaped convex surface facing upward. This ensures that when the lenses 30 enter the V-shaped groove 11c with the bottom surface facing upward or downward, they can be turned into a flat posture with the bottom surface facing downward by the action of the V-shaped groove 11c, so that the vertical surface of the lens body strictly meets the directional alignment requirements.

[0045] S3: When the lens 30 is separated from the V-groove 11c and continues to move upward, Figure 3 As shown, the lens 30 in a horizontal position is guided by the guide groove 11i and enters the diversion track 11e. Since the width z of the diversion track 11e is greater than the width y of the rectangular array formed by the four pillars of the lens 30, when the lens 30 is transported forward in the width direction of the rectangular array of its pillars, the pillar array cannot be smoothly inserted into the diversion track 11e. After continuous vibration transmission, the lens 30 in this posture is thrown to the falling empty areas 11f on both sides to be transported again. Since the length x of the rectangular array is greater than the width z of the diversion track 11e, when the lens 30 is transported forward in the length direction of the rectangular array of its pillars, the pillar array can be smoothly inserted into the diversion track 11e with the gap in the length direction thereof, thereby screening out the lens 30 with the correct transmission posture, so that the horizontal plane of the lens body strictly meets the directional alignment requirements.

[0046] S4: After the lens 30 material is transported to each linear groove 11h of the linear track 11g along the diversion track 11e, the vertical and horizontal surfaces of each lens 30 are correctly aligned and squeezed into the arrangement track 12 set at intervals at the tail end of the linear track 11g under the vibration of the vibration source 20. Figure 3As shown, due to the static setting of the arrangement track 12, the position of the sensor light 12b at its entrance remains unchanged, and the sensor light 12b senses and counts the lenses 30 entering the arrangement slot 12a one by one. When the count value reaches the capacity limit of the arrangement slot 12a, it is fed back to the controller and the execution of the vibration source 20 is slowed down or paused, slowing down the transmission rhythm of the lens 30 so that the automatic suction nozzle can absorb the statically arranged lens 30 in the arrangement slot 12a. At this time, the pointing posture of the lens 30 has been corrected by the vibration disk mechanism and can be smoothly transmitted to the SMT placement machine for automatic assembly.

[0047] Through the above operation, all lenses are in an indiscriminate arrangement state with the arc convex surface facing upward, and then the irregular posture of the lens column array is eliminated by setting the size of the diversion track 11e. The device does not need to set up a complex motion actuator, and can make the horizontal and vertical surfaces of the lens body strictly meet the directional alignment requirements, effectively reducing the manpower, material and time costs of lens production, avoiding the limitations of complex motion actuators, and effectively improving the production efficiency of LED lens batch production lines.

[0048] In this embodiment, the surface of the diverter groove 11a where the leading end of the V-groove 11c connects is higher than the top surface of the V-groove 11c, while the surface of the diverter groove 11a where the trailing end of the V-groove 11c connects is lower than the lowest point within the V-groove 11c. This ensures that the lens 30, under the action of gravity, smoothly falls into the leading end of the V-groove 11c and smoothly exits the trailing end of the V-groove 11c, effectively transitioning the lens 30 from an inclined position to a flat position.

[0049] In this embodiment, the tail end portion 11j of the V-shaped groove 11c is pointed, which serves as a slow transition for the lens 30 to escape from the V-shaped groove 11c, preventing the lens 30 from instantly losing its support and inducing a new flipping posture, thereby ensuring the accuracy of the V-shaped groove 11c in adjusting the posture of the lens 30; at the same time, among the groove walls on both sides of the V-shaped groove 11c, the groove wall facing the outside of the top plate 10 is in contact with the side wall of the diverter groove 11a, thereby reducing the outer support surface of the V-shaped groove 11c to allow the lens 30 to tilt smoothly, ensuring that the lens 30 in edge transmission can be smoothly embedded in the V-shaped groove 11c.

[0050] In this embodiment, the angle bisectors of the inner walls on both sides of the V-shaped groove 11c are vertical lines, so that the V-shaped groove 11c itself has symmetry and is not affected by the inclined surface of the spiral track 11. Under the symmetrical setting of the inner walls on both sides of the V-shaped groove 11c, the vertically embedded lenses 30 can all tilt toward one side of their bottom surfaces; at the same time, the width of the V-shaped groove 11c is smaller than the width of the falling hole 11d. When the lenses 30 are sent for transportation and stacking, the width setting of the falling hole 11d can provide sufficient falling space for the upper lenses 30, thereby improving the screening accuracy and preventing incorrectly arranged lenses from being mixed into the next step.

[0051] In this embodiment, the angle between the track surface of the spiral track 11 and the horizontal plane is 2° to 5°, preferably 2°, so as to ensure that the spiral track 11 is in a slightly tilted state. When the lens 30 is allocated to the edge area of ​​the diversion groove 11a, the slightly tilted state of the spiral track 11 will not cause functional interference to the V-groove 11c, ensuring the smooth implementation of the V-groove 11c to adjust the posture of the lens 30.

[0052] Example 2

[0053] The difference between this embodiment and the first embodiment is that the vibration excitation direction of the top plate 10 is increased, thereby further improving the accuracy of the V-shaped groove 11 c in flipping the lens.

[0054] like Figure 16 As shown, the vibration source 20 is provided on the radial vibrator 21. The vibration excitation of the radial vibrator 21 is in the direction A (21x). The direction A (21x) is oriented from the center of the cross-section circle of the top plate 10 to the V-shaped groove 11c area (as shown in FIG. Figure 3 21x).

[0055] The working principle of this embodiment is as follows:

[0056] Start the vibration source 20 and the radial vibrator 21 to make the top plate 10 press Figure 16 As shown, the top plate 10 simultaneously performs vertical reciprocating vibration, tangential reciprocating torsion, and radial reciprocating vibration as shown in direction A (21x), so that the lens 30 is repeatedly thrown up and rises along the spiral track 11, similar to step S2 in embodiment 1. When the lens 30 enters the V-shaped groove 11c, it flips over and is embedded in the groove, as shown in FIG. Figure 17 As shown, the lens 30 is subjected to the vibration transmission effect of the vibration source 20. At the same time, it is also subjected to the reciprocating vibration effect of the radial vibrator 21 in the direction A (21x). Since the lower end of the vertically embedded lens 30 is affixed to the V-shaped groove 11c, the reciprocating vibration of the lens 30 driven by the V-shaped groove 11c can be divided into the following two situations:

[0057] (1) When the top plate 10 is driven by the radial vibrator 21 to swing toward the right (direction depends on the direction of the Figure 17 ), the bottom end of the lens 30 is pulled by the V-shaped groove 11c, and the upper part of the lens 30 generates inertia toward the left. However, because the arc convex surface on the left side of the lens 30 presses against the wall of the V-shaped groove 11c to form a stable support, the lens 30 cannot tip toward the left, and the V-shaped groove 11c then drives the entire lens 30 to move toward the right;

[0058] (2) When the top plate 10 is driven by the radial vibrator 21 to swing toward the left (direction depends on the direction of the Figure 17), the bottom end of the lens 30 is pulled by the V-shaped groove 11c, and the upper part of the lens 30 generates inertia toward the right. Since there is a large empty space between the flat bottom surface on the right side of the lens 30 and the wall of the V-shaped groove 11c, the two cannot form a stable supporting contact, causing the upper part of the lens 30 to tilt toward the right under the action of its own inertia and smoothly adhere to the wall of the V-shaped groove 11c.

[0059] Through the above operation, the lens 30 can be effectively promoted to tilt correctly toward its bottom surface. Similarly, it can be known that when the bottom surface of the lens 30 faces the direction of the bottom surface of the lens 30, the lens 30 will tilt correctly. Figure 17 When the direction is opposite to that shown, the lens 30 will still tilt toward the bottom of the larger assembly space, and then smoothly form a lens material with the correct direction arrangement after escaping the V-shaped groove 11c. Through the action of the radial vibrator 21 of this embodiment, the accuracy of flipping the lens 30 in the V-shaped groove 11c to uniformly face the convex surface upward can be further improved, the error rate can be reduced, and the uniformity of the lens delivery direction can be improved, thereby optimizing and improving the production efficiency of the LED lens batch production line.

[0060] The above description is only a preferred embodiment of the present invention and does not constitute a formal limitation to the present invention. It should be understood that for ordinary technicians in this field, the embodiments may be replaced by other equivalent forms, which should be included in the scope of protection of the present invention as long as they meet the feature range defined in the claims.
