Description

Technical Field

[0001] The present invention relates to the technical field of LED street lamp assembly and testing, and in particular to a smart LED street lamp assembly and testing production line and a method for using the same. Background Art

[0002] Smart LED street lights have gradually entered people's field of vision with advantages such as directional light emission, low power consumption, good driving characteristics, fast response speed, high earthquake resistance, long service life, and green environmental protection, becoming a new generation of energy-saving light sources with advantages. Therefore, smart LED street lights will become the best choice for energy-saving transformation of road lighting. Smart LED street lights fully consider the actual situation of urban road lighting, and use single-chip control technology to dynamically and intelligently manage the illumination of street lights to achieve humanization of street lights.

[0003] Since LED street lights have the characteristic of extremely fast transient response that other street lights do not have, it is very easy to use KHZ-level pulse width modulation to adjust the duty cycle of the LED street lights. For example, if they are on for 0.5ms and off for 0.5ms within 1ms, the brightness is 50% of the full brightness, which means the overall brightness of the lamp is adjusted.

[0004] During the assembly and testing process of smart LED street lights, it is necessary to perform optical inspection on the finished products after assembling the outer screen. Most traditional inspection methods inspect and process the finished products in fixed positions. However, due to the above-mentioned characteristics of smart LED street lights, corresponding optical inspection instruments are required for inspection and processing. At this time, if the external light source enters the optical inspection instrument, the inspection accuracy will be greatly reduced, affecting the inspection effect.

[0005] At the same time, when the external screen of the smart LED street lamp is installed too loosely, the position of the external screen and the LED street lamp source will be offset after the specific installation, which will affect the illumination intensity. The light detection in a fixed state cannot verify the above problem, so the detection accuracy is greatly reduced.

[0006] In order to address the above problems, there is an urgent need for a smart LED street lamp assembly and testing production line and a method of using the same. Summary of the invention

[0007] The purpose of the present invention is to provide a smart LED street lamp assembly and testing production line and a method of using the same to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned purpose, one of the purposes of the present invention is to provide a smart LED street lamp assembly and testing production line, including a plurality of clamping components for clamping and fixing LED street lamps and a transmission component for conveying the clamping components, wherein slide rails are arranged on both sides of the transmission component, a pad is fixedly connected to the bottom end of the slide rail, a protrusion is arranged in the middle of the slide rail, an extension is arranged at both ends of the slide rail, a slide groove is opened on the side of the slide rail, a connecting shaft is arranged at both ends of the clamping component, a toothed disc is coaxially connected to the end of the connecting shaft, the toothed disc is slidably connected to the inner end of the slide groove at the corresponding position, and the two slide grooves are provided with tooth block groups at symmetrical positions at the bottom end of the protrusion and symmetrical positions at the top end, a pair of optical detection instruments for optically detecting the LED street lamps passing by are symmetrically and obliquely arranged on both sides of the top end of the transmission component, and the two symmetrical tooth block groups are respectively arranged at the two end positions of the optical detection instrument, a guide frame is arranged on both sides of the top end of the clamping component, and a connecting sleeve is arranged at the bottom end of the optical detection instrument;

[0009] During the process of moving the two ends of the clamping assembly along the extension to the protruding portion, the two guide frames move closer to each other to cooperate with the clamping assembly to clamp and fix the installed LED street lamp, and move to the contact position with the tooth block group. The connecting shaft cooperates with the toothed disc to flip, and before it is about to be separated from the tooth block group, its top end is attached to the bottom end of the connecting sleeve. A light source guide chamber is formed between the two guide frames in the close state and the inner end of the attached connecting sleeve, which is inclined, closed and directly opposite to the light source point of the LED street lamp in the clamped state.

[0010] As a further improvement of the present technical solution, the transmission component includes a transmission belt and a pair of drive shafts installed on the inner sides of both ends of the transmission belt. A gap is opened in the middle position of the transmission belt for flipping and adjusting the clamping component. Both ends of the drive shaft are rotatably connected to support frames, and a servo motor coaxially connected to the end of the drive shaft is arranged on the side of one of the support frames, and each clamping component is equidistantly arranged on the outer surface of the transmission belt.

[0011] As a further improvement of the present technical solution, the clamping assembly includes a pair of clamping plates and a pair of connecting blocks. The top of the two clamping plates are provided with top openings for placing LED street lamps, and the ends of the two guide frames are coaxially connected to the connecting shafts at corresponding positions. The two guide frames are respectively fixed at the top positions of the two clamping plates, and the two connecting blocks are respectively symmetrically fixed at the two end positions of the outer side of the conveyor belt, and the connecting shaft maintains a rotational connection with the connecting blocks in a fixed state.

[0012] As a further improvement of the present technical solution, a reset spring is connected between the connecting shaft and the inner end connection position of the connecting block, and in the process of the toothed disk moving from the extended part to the protruding part, the two connecting shafts squeeze the two clamping plates against each other to make their sides fit together, and compress the reset spring at the corresponding position.

[0013] As a further improvement of the technical solution, a torsion spring is connected to the connection position between the outer side of the connecting shaft and the side surface of the connecting block.

[0014] As a further improvement of the technical solution, both sides of the optical detection instrument are coaxially connected with swing shafts, and the ends of the two swing shafts are rotatably connected with support plates.

[0015] As a further improvement of the technical solution, a return coil spring is provided between the connection position between the outer side of the swing shaft and the inner side of the support plate.

[0016] The second object of the present invention is to provide a method for using a smart LED street lamp assembly and testing production line, comprising the following method steps:

[0017] S1. Place the LED street lamps to be installed on the top openings of the two clamping plates at the edge of the transmission assembly in sequence. The two ends of the clamping assembly are respectively located at the extensions of the two slide rails. The two guide frames are separated from each other to form a gap. The tops of the guide frames form a vertical upward channel with a notch. Slide the matching outer screen through the channel to the top of the LED street lamp housing.

[0018] S2, the servo motor drives one of the drive shafts to rotate, and drives the transmission belt and the other drive shaft to rotate through the drive shaft;

[0019] S3. The assembled LED street lamp is driven to move from the extended part of the slide rail to the protruding part by the rotating conveyor belt. The protruding part will press the toothed disc, and the two clamping plates are pushed by the two connecting shafts, driving the two clamping plates and the guide frame in the separated state to approach each other until their sides fit each other, thereby changing the space size formed by the two top openings, and the assembled LED street lamp is clamped and fixed by the contracted top opening;

[0020] S4. After the toothed disc and the toothed block group come into contact, a meshing connection is formed between the two. After the toothed disc continues to move, the toothed disc, the connecting shaft, the guide frame and the clamping plate are turned over by the toothed block group. The tops of the two guide frames in the fitted state are just moved to a position directly below another optical detection instrument. A light source guide chamber is re-formed between the lower connecting sleeve and the two guide frames in the fitted state, which is inclined, closed and directly opposite to the light source point of the LED street light in the clamped state.

[0021] S5. When the sprocket is separated from the tooth block group at the current position, the torsion spring will lose the external force and drive the entire sprocket, connecting shaft, guide frame and clamping plate to reset and return to a horizontal state until they move to the inner end of the other extension. The interval length between the two slide rails gradually increases, and the reset spring loses the external force and drives the two connecting shafts away from each other in the reverse direction, causing the two sprockets to fit back to the inner end of the slide groove at the extension position and move the two clamping plates away from each other.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the smart LED street lamp assembly test production line and its use method, an inclined, closed light source guide chamber is formed between the connecting sleeve and the two guide frames in the fitted state, which is directly opposite to the LED street lamp light source point in the clamped state. The external light source is shielded by the current light source guide chamber, so that the light source detected by the optical detection instrument is completely emitted by the LED street lamp light source point currently in the clamping component placement position, reducing the influence of irrelevant factors on the detection work. At the same time, the clamp in the inclined state can verify the installation status of the external screen to determine whether the external screen meets the size standard.

[0024] 2. In the smart LED street lamp assembly test production line and its use method, the flipping function of the optical detection instrument is realized by setting a swing shaft and a support plate. When the guide frame is about to contact the connecting sleeve, a thrust will be formed on its contact position, prompting it to flip in the moving direction, and it will be spliced ​​with the guide frame during the flipping process to form a light source guide chamber to guide light, isolate external light sources, and improve stability during the test.

[0040] See also Figure 1-Figure 8As shown, one of the purposes of this embodiment is to provide a smart LED street lamp assembly and testing production line, including a plurality of clamping components 20 for clamping and fixing LED street lamps and a transmission component for conveying the clamping components 20, slide rails 40 are arranged on both sides of the transmission component, a pad 420 is fixedly connected to the bottom end of the slide rail 40, a protrusion is arranged in the middle position of the slide rail 40, an extension is arranged at both ends of the slide rail 40, a slide groove 410 is opened on the side of the slide rail 40, and a connecting shaft 230 is arranged at both ends of the clamping component 20, and the ends of the connecting shaft 230 are connected to the ends of the connecting shaft 230. The shaft is connected with a toothed disc 231, which is slidably connected to the inner end of the slide groove 410 at the corresponding position, and the two slide grooves 410 are provided with tooth block groups 411 at the symmetrical positions at the bottom and the top of the protruding part, and a pair of optical detection instruments 30 for optically detecting the passing LED street lamps are symmetrically and obliquely arranged on both sides of the top of the transmission component, and the two symmetrical tooth block groups 411 are respectively arranged at the two ends of the optical detection instrument 30, and the two sides of the top of the clamping component 20 are provided with guide frames 211, and the bottom of the optical detection instrument 30 is provided with a connecting sleeve 310;

[0041] During the process of moving the two ends of the clamping assembly 20 along the extension to the protruding portion, the two guide frames 211 move closer to each other to cooperate with the clamping assembly 20 to clamp and fix the installed LED street lamp, and move to the contact position with the tooth block group 411, the connecting shaft 230 cooperates with the toothed disc 231 to flip, and before it is about to be separated from the tooth block group 411, its top end is attached to the bottom end of the connecting sleeve 310, and an inclined, closed light source guide chamber is formed between the two guide frames 211 in the close state and the inner end of the attached connecting sleeve 310, which is directly opposite to the light source point of the LED street lamp in the clamped state.

[0042] In specific use, during the assembly and testing of the LED street lamp, the LED street lamp to be installed is first placed on the clamping assembly 20 at the edge of the transmission assembly. At this time, the two ends of the clamping assembly 20 are respectively located at the extension of the two slide rails 40, and the two guide frames 211 are separated from each other to form a gap, and the top of the guide frames 211 forms a vertical upward channel with a notch, such as Figure 5 As shown, at this stage, the matching outer screen is slid through the channel to the top of the LED street lamp housing;

[0043] After the assembly work is completed, the clamping assembly 20 is driven by the transmission assembly to move along between the two slide rails 40, so that the two ends of the clamping assembly 20 move along the extension part toward the protruding part thereof, such as Figure 7During this process, as the interval between the two slide rails 40 is gradually shortened, a thrust is applied to the two connecting shafts 230 and the toothed disc 231, causing the two guide frames 211 at the top of the clamping assembly 20 to move closer to each other until the end of the toothed disc 231 slides into the protruding portion. At this time, the sides of the two guide frames 211 fit together to form a vertical upward channel without a gap, and cooperate with the clamping assembly 20 to clamp and fix the LED street lamp to be tested, maintain its fixed state, and prevent position displacement during transportation;

[0044] It is worth noting that the fixed LED street lamp does not include the outer screen at this time, because the outer screen is clamped on the inner end of the opening at the top of the LED street lamp. When the size of the outer screen is smaller than the opening, although it can be clamped in the inner end of the opening, when the entire LED street lamp is not in a horizontal state, the small-sized outer screen will be offset. Therefore, in order to verify the influence of the small-sized outer screen on the LED street lamp at different offset angles, and at the same time verify whether the size of the outer screen meets the requirements, the transmission component continues to drive the clamping component 20 to move along the protrusion of the slide rail 40 until the two toothed discs 231 move to the slide groove 41. 0, the tooth block group 411 at the bottom of the inner end of the tooth block group 411 at this time will mesh with the toothed disc 231, driving the toothed disc 231, the connecting shaft 230, the clamping assembly 20 and the two guide frames 211 in the fitted state to flip, and the flip angle is continuously increased until the toothed disc 231 moves to the end position of the tooth block group 411 at this time, the top ends of the two guide frames 211 in the fitted state just move to the position directly below the adjacent optical detection instrument 30, and the top ends of the two guide frames 211 in the flipped state just fit directly below the connecting sleeve 310 at the current position, as shown in FIG. Figure 8 As shown, at this time, an inclined, closed light source guide chamber is formed between the connecting sleeve 310 and the two guide frames 211 in the fitted state, and the light source guide chamber is directly opposite to the light source point of the LED street lamp in the clamping state. The external light source is shielded by the current light source guide chamber, so that the light source detected by the optical detection instrument 30 is completely emitted by the LED street lamp light source point currently in the placement position of the clamping component 20, reducing the influence of irrelevant factors on the detection work. At the same time, the clamping plate 210 in the inclined state can verify the installation state of the external screen to determine whether the external screen meets the size standard;

[0045] After completing an optical inspection, the clamping assembly 20 continues to move until the toothed discs 231 at both ends of the clamping assembly 20 contact the tooth block group 411 at the top inner end of the slide groove 410, and the two mesh, so that the toothed discs 231, the connecting shaft 230, the clamping assembly 20 and the two guide frames 211 in the fitted state are flipped in the opposite direction until the toothed disc 231 moves to the end position of the tooth block group 411 in this position. At this time, the top ends of the two guide frames 211 in the fitted state just move to the position directly below another optical inspection instrument 30. At this time, a light source guide chamber that is inclined, closed and directly opposite to the light source point of the LED street light in the clamping state is re-formed between the lower connecting sleeve 310 and the two guide frames 211 in the fitted state, so as to verify the clamping assembly 20 and the external screen under different offset conditions.

[0046] Further, the transmission assembly includes a transmission belt 10 and a pair of drive shafts 110 installed on the inner sides of both ends of the transmission belt 10. A gap for the clamping assembly 20 to perform flipping adjustment is provided in the middle of the transmission belt 10. Both ends of the drive shaft 110 are rotatably connected to support frames 120, and a servo motor 130 coaxially connected to the end of the drive shaft 110 is provided on the side of one of the support frames 120. Each clamping assembly 20 is equidistantly arranged on the outer surface of the transmission belt 10.

[0047] During the process of adjusting the position of the clamping assembly 20, one of the drive shafts 110 is driven to rotate by the servo motor 130, and the drive shaft 110 drives the conveyor belt 10 and the other drive shaft 110 to rotate, so as to synchronously adjust the position of each clamping assembly 20 on the surface of the conveyor belt 10, and move the two ends of the clamping assembly 20 from the extension of one of the slide rails 40 (LED street lamp assembly position) to the protrusion (test position for the assembled LED street lamp), and finally move to the other extension (the detachment position of the finished LED street lamp after the test).

[0048] Furthermore, the clamping assembly 20 includes a pair of clamping plates 210 and a pair of connecting blocks 220. The tops of the two clamping plates 210 are provided with top openings for placing LED street lamps, and the ends of the two guide frames 211 are coaxially connected with the connecting shafts 230 at the corresponding positions. The two guide frames 211 are respectively fixed at the top positions of the two clamping plates 210, and the two connecting blocks 220 are respectively symmetrically fixed at the two ends of the outer side of the conveyor belt 10, and the connecting shaft 230 is rotationally connected with the connecting block 220 in the fixed state. During the assembly process, the two toothed plates 231 are both at the outer extension of the two slide rails 40, the two toothed plates 231 are not squeezed, the two clamping plates 210 and the two guide frames 211 are separated from each other, and a vertical channel with a notch is formed at the top thereof, and the channel is connected to the top of the two top openings. The LED street lamp to be assembled is slid into the inner ends of the two top openings through the channel, and the outer screen is slid along the channel and installed to the top installation position of the LED street lamp, the position of the LED street lamp and the outer screen is corrected to improve the assembly efficiency.

[0049] Specifically, a return spring is connected between the connecting shaft 230 and the inner end connecting position of the connecting block 220, and when the toothed disc 231 moves from the extension portion to the protruding portion, the two connecting shafts 230 press the two clamping plates 210 against each other, so that their sides fit together, and compress the return springs at the corresponding positions. When the toothed disc 231 is at the protruding portion, the interval length between the two slide rails 40 is the shortest, which cannot meet the length of the two connecting shafts 230 plus the two separated clamping plates 210. The protruding portion will compress the toothed disc 231, and the two connecting shafts 230 will push the two clamping plates 210, driving the two clamping plates 210 in the separated state and the guide rails 40 to move. The frames 211 approach each other until their sides fit together, thereby changing the size of the space formed by the two top openings, and the assembled LED street lamp is clamped and fixed by the shrunk top opening to maintain its stability during the detection process. At the same time, when the toothed disc 231 moves out of the protruding portion and moves toward the extension portion, the interval length formed between the two slide rails 40 gradually increases. At this time, the reset spring loses the external force and will drive the two connecting shafts 230 away from each other in the opposite direction, causing the two toothed discs 231 to fit again to the inner end of the slide groove 410 at the extension portion, and the two clamping plates 210 to move away from each other, so as to disengage the LED street lamp after the assembly and testing work is completed.

[0050] In addition, a torsion spring 232 is connected to the connection position between the outer side of the connecting shaft 230 and the side of the connecting block 220. After the toothed disc 231 contacts the tooth block group 411, an engagement connection is formed between the two. After the toothed disc 231 continues to move, the toothed disc 231, the connecting shaft 230, the guide frame 211 and the splint 210 are driven to flip through the tooth block group 411. At this time, the connecting shaft 230 will drive the torsion spring 232 to contract until the toothed disc 231 is separated from the tooth block group 411 at the current position. The torsion spring 232 will lose external force and reversely drive the entire toothed disc 231, the connecting shaft 230, the guide frame 211 and the splint 210 to reset and return to a horizontal state, so as to facilitate secondary position adjustment and final separation work at a later time.

[0051] Since the connecting sleeve 310 arranged at the bottom end of the optical detection instrument 30 is in an inclined state, it is easy to form an obstacle to the guide frame 211 during the movement. In addition, the optical detection instrument 30 is coaxially connected with the swing shaft 330 on both sides, and the ends of the two swing shafts 330 are rotatably connected with the support plate 320. The flipping function of the optical detection instrument 30 is realized by the set swing shaft 330 and the support plate 320. When the guide frame 211 is about to contact with the connecting sleeve 310, a thrust will be formed on the contact position, prompting it to flip in the moving direction, and it will be spliced ​​with the guide frame 211 during the flipping process to form a light source guide chamber to guide light, isolate external light sources, and improve stability during the test process.

[0052] Furthermore, a reset spring 331 is provided between the outer side of the swing shaft 330 and the inner side of the support plate 320. When the connecting sleeve 310 is pushed to drive the optical detection instrument 30 to flip, the optical detection instrument 30 will drive the reset spring 331 to be in a compressed state through the two swing shafts 330 until the test is completed, and the guide frame 211 moves out of the current splicing position. Then, under the reaction force provided by the reset spring 331, the optical detection instrument 30 and the connecting sleeve 310 are driven to reset.

[0053] The second purpose of this embodiment is to provide a method for using a smart LED street lamp assembly and testing production line, including the following method steps:

[0054] S1. The LED street lamps to be installed are sequentially placed on the top openings of the two clamping plates 210 at the edge of the transmission assembly. The two ends of the clamping assembly 20 are respectively located at the extensions of the two slide rails 40. The two guide frames 211 are separated from each other to form a gap. The tops thereof form a vertical upward channel with a notch. The matching outer screen is slid into the upper part of the LED street lamp housing through the channel.

[0055] S2, the servo motor 130 drives one of the drive shafts 110 to rotate, and the drive shaft 110 drives the conveyor belt 10 and the other drive shaft 110 to rotate;

[0056] S3, the transmission belt 10 in the rotating state drives the assembled LED street lamp to move from the extension of the slide rail 40 to the protruding portion, the protruding portion will press the toothed disc 231, and the two connecting shafts 230 will push the two clamping plates 210, driving the two clamping plates 210 and the guide frame 211 in the separated state to approach each other until their sides fit together, thereby changing the space size formed by the two top openings, and the assembled LED street lamp is clamped and fixed by the contracted top opening;

[0057] S4. After the toothed disc 231 contacts the tooth block group 411, a meshing connection is formed between the two. After the toothed disc 231 continues to move, the tooth block group 411 drives the toothed disc 231, the connecting shaft 230, the guide frame 211 and the clamping plate 210 to flip. In the fitted state, the top ends of the two guide frames 211 just move to a position directly below another optical detection instrument 30. In the lower position, the connecting sleeve 310 and the two guide frames 211 in the fitted state re-form an inclined, closed light source guide chamber that is directly opposite to the light source point of the LED street light in the clamped state.

[0058] S5, the toothed disc 231 is separated from the tooth block group 411 at the current position, and the torsion spring 232 will lose the external force, and reversely drive the entire toothed disc 231, the connecting shaft 230, the guide frame 211 and the clamping plate 210 to reset and return to a horizontal state until they move to the inner end of the other extension part. The interval length between the two slide rails 40 gradually increases, and the reset spring loses the external force, and reversely drives the two connecting shafts 230 away from each other, prompting the two toothed discs 231 to re-attach to the inner end of the slide groove 410 at the extension part position, and move the two clamping plates 210 away from each other.
