A lamp strip lens feeder

Abstract

This utility model discloses a light strip lens feeder, including a vibratory feeder body. The vibratory feeder body includes a hopper, and a discharge track is provided at the outlet of the hopper. A screening track is connected to the discharge track. A screening groove is constructed on the rear side of the V-shaped groove on the screening track. The screening groove is adapted to engage the end face protrusions of the lenses. As the vibratory feeder body vibrates, the lenses in the hopper gradually enter the screening track along the discharge track until the lenses fall into the V-shaped groove. Several lenses will then flip to a uniform orientation. Subsequently, the lenses gradually enter the screening groove, causing the two end face protrusions of the lenses to engage in the screening groove. Thus, under the constraint of the two end face protrusions and the screening groove, several lenses are screened to a uniform circumferential position. This utility model achieves a uniform circumferential position of the lenses through the cooperation of the screening groove and the end face protrusions on the lenses, eliminating the need for a sensing device on the automatic mounting robot arm, thereby reducing production line costs.

Description

Technical Field

[0001] This utility model relates to the field of LED strip manufacturing technology, and in particular, to an LED strip lens feeder. Background Technology

[0002] The LED strip mainly consists of a PCB board, LED chips, and lenses. During the production process, the lenses can be automatically transported using a vibratory feeder. For example, since the top of the refractive lens is a spherical convex surface, it can be oriented and flipped by feeding the refractive lens into the V-groove in the vibratory feeder track, so that the light-emitting surface of the refractive lens is transported in a uniform orientation.

[0003] However, when automatically attaching lenses to LED strips, the feeder can only drive the lenses to a uniform orientation, but cannot select them to a uniform circumferential position. In other words, the angle of the lenses supplied by the feeder to the automated placement arm is disordered, causing the automated placement to malfunction. Alternatively, sensors such as vision mechanisms could be installed on the automated placement arm to identify the circumferential position of the lenses, but this would increase production line costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a lamp strip lens feeder.

[0005] The objective of this utility model is achieved through the following technical solution: A light strip lens feeder includes a vibratory feeder body, the vibratory feeder body including a hopper, a discharge track provided at the outlet of the hopper, a screening track joined to the discharge track, a V-shaped groove provided on the screening track, and a screening groove constructed on the screening track behind the V-shaped groove, the screening groove being adapted to engage with the end face protrusions of the lens; under the vibration of the vibratory feeder body, two of the end face protrusions of the lens engage with the screening groove.

[0006] Preferably, multiple screening tracks are arranged side by side.

[0007] Preferably, multiple guide grooves are arranged side by side on the discharge track, and each of the guide grooves corresponds to a screening track.

[0008] Preferably, a conveying track is connected to the screening track.

[0009] Preferably, a sensor is provided on the side wall of the screening track, and the sensor is adapted to detect whether there is a protrusion on the other end face of the lens passing through the screening track.

[0010] Preferably, the sensing element includes a photoelectric sensor.

[0011] Preferably, the sensing element includes a press-type sensor.

[0012] Preferably, a material rejection mechanism is provided on the screening track behind the sensing element.

[0013] Preferably, the rejection mechanism includes an ejector rod that can be ejected, the ejector rod being opposite to the suspension end of the lens; when the ejector rod is ejected, the lens can flip and fall off the screening track.

[0014] Preferably, a discharge channel is provided below the ejector rod.

[0015] The beneficial effects of this invention are as follows: As the vibrating plate vibrates, the lenses in the hopper gradually enter the screening track along the discharge track. Once the lenses fall into the V-shaped groove, several lenses flip over to face the same direction. Subsequently, the lenses gradually enter the screening trough, causing the two end face protrusions of the lenses to engage within the trough. Thus, under the constraint of the two end face protrusions and the screening trough, several lenses are screened to a uniform circumferential position. Compared with existing technologies, this invention achieves a uniform circumferential position of the lenses through the cooperation of the screening trough and the end face protrusions on the lenses, eliminating the need for a sensing device on the automatic mounting robot arm, thereby reducing production line costs.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 , Figure 2As shown, a light strip lens feeder includes a vibratory feeder body 1, which may include a hopper 2 and a vibration source. Under the vibration of the vibration source, the lens 13 in the hopper 2 will enter the discharge track 3 at the outlet along the spiral conveying surface of the hopper 2; and the discharge track 3 is connected to a screening track 4, for example, the inlet end of the screening track 4 is also constructed with a V-shaped groove 5. The lens 13 will enter the screening track 4 under the action of vibration force, and fall into the V-shaped groove 5 due to gravity, ultimately realizing the directional flipping of the lens 13.

[0020] A screening groove 6 is constructed on the rear side of the V-shaped groove 5 on the screening track 4, and the width of the screening groove 6 is adapted to the diameter of the end face protrusion 14 of the lens 13. Under the action of vibration, the lens 13 will gradually enter the screening groove 6, and the two end face protrusions 14 of the lens 13 will be engaged in the screening groove 6. Thus, under the limitation of the two end face protrusions 14 and the screening groove 6, several lenses 13 are screened to a uniform circumferential position.

[0021] For example, a conveying track 8 is also connected to the end of the screening track 4, through which the lenses 13 in a uniform posture are transported to one side of the automatic mounting robot arm. In a preferred example, multiple guide grooves 7 can be arranged side by side on the discharge track 3, and multiple screening tracks 4 and conveying tracks 8 are also arranged side by side. In this way, with the one-to-one cooperation of the guide grooves 7, screening tracks 4, and conveying tracks 8, the feeder disclosed herein can realize the simultaneous feeding of multiple rows of lenses 13.

[0022] In some embodiments, a sensor 9 is also provided on the side wall of the screening track 4. The sensor 9 can detect whether there is another end face protrusion 14 on the lens 13 passing through the screening track 4, and thus determine whether the lens 13 is a qualified product.

[0023] It is understandable that if two of the three end face protrusions 14 on the lens 13 are damaged, the lens 13 will either be unable to be inserted into the screening groove 6 and fall off the screening track 4; or it will be inserted into the screening groove 6 with its only remaining end face protrusion 14, but since a single end face protrusion 14 cannot limit the position, the lens 13 will still be vibrated until its center of gravity deviates from the screening track 4, until the lens 13 also falls off. If only one end face protrusion 14 on lens 13 is damaged, it may result in a defective lens 13 being unexpectedly conveyed to the next process via the feeder.

[0024] Because the sensor 9 in this disclosure can detect the qualification status of the lens 13 in a timely manner, the aforementioned technical problems can be avoided.

[0025] In possible examples, the sensing element 9 may include a photoelectric sensor or a pressure sensor. For example, a photoelectric sensor can monitor whether an end face protrusion 14 passes between the transmitting and receiving ends through the cooperation of the transmitting and receiving ends; while a pressure sensor can detect and sense the pressure applied to the end face protrusion 14 when it passes by in the form of a contact switch.

[0026] For example, a rejection mechanism 10 can be installed on the screening track 4 behind the sensor 9. The rejection mechanism 10 can promptly remove unqualified lenses 13. In a specific example, the rejection mechanism 10 includes an ejector rod 11 that can be ejected. For example, the ejector rod 11 can be ejected by an electric cylinder, a pneumatic cylinder, or magnetic actuation. In particular, the ejector rod 11 is opposite to the suspension end of the lens 13 below. When the sensor 9 detects that the lens 13 is unqualified, according to a certain timing sequence, it can determine that the lens 13 is opposite the ejector rod 11. Then, the ejector rod 11 ejects, causing the lens 13 to flip and fall off the screening track 4.

[0027] In addition, a discharge channel 12 is provided inside the hopper 2 below the ejector rod 11, through which unqualified lenses 13 can be directly discharged to avoid repeated screening. In the example with a conveyor track 8, a screening trough 6 is also provided on the conveyor track 8.

[0028] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
