Description

Technical Field

[0001] This invention relates to the field of LED spectrophotometry technology, specifically a spectrophotometer for testing LED lamps. Background Technology

[0002] An LED is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. Compared with ordinary lamps (such as incandescent lamps), LED lights have advantages such as energy saving, long life, good applicability, short response time, and environmental protection. After LEDs are packaged into LED beads, in order to determine their luminous efficacy, they are usually tested on a spectrometer, and the LED beads are screened according to their luminous efficacy. Therefore, it is necessary to use a spectrometer for LED lamp testing to test the LED beads.

[0003] LED lamp testing spectrometers are automated equipment used in the LED production and testing field to perform spectroscopic testing and sorting of LED lamp beads. They typically use a vibrating screen, conveying components, a shifting fork transfer mechanism, a probe mechanism, and a testing mechanism to sort, convey, and position LEDs one by one. The probes contact the LEDs to energize them and make them light up. The testing mechanism then detects their optical parameters such as brightness and wavelength and sends them to the corresponding storage boxes according to different grades.

[0004] In existing LED light testing spectrometers, the probe mechanism needs to repeatedly contact and detach from the LED contact points during testing. However, LED contact points are thin, making docking and positioning difficult. Furthermore, adhesive residue often remains on the surface of LEDs after packaging. This adhesive can easily enter the probe's connection groove or adhere to the contact points, causing blockage of the connection groove and poor contact at the contact points. Consequently, this leads to unstable lighting, interruption of spectrometer testing, or reduced efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a spectrometer for LED lamp detection, so as to solve the problem of unstable spectrometer detection efficiency in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A spectrometer for testing LED lights includes a vibrating screen, a conveying assembly, and a testing assembly. The testing assembly is located between the vibrating screen and the conveying assembly. The conveying assembly includes a plurality of inlet slots, a conveying channel, and a plurality of placement slots. The plurality of inlet slots are symmetrically arranged along the conveying channel, and the plurality of placement slots correspond one-to-one with the plurality of inlet slots.

[0008] The detection assembly includes a fork transplanting mechanism, a probe mechanism, and a detection mechanism. One end of the fork transplanting mechanism is connected to a vibrating screen, and the other end of the fork transplanting mechanism is connected to a conveyor. The probe mechanism is located below the fork transplanting mechanism, and the detection mechanism is located above the fork transplanting mechanism. The axis of the probe mechanism and the axis of the detection mechanism are coincident.

[0009] The probe mechanism includes a drive group and two moving tubes. The moving tubes are connected to the drive group. An air pipe is provided inside the drive group and the moving tubes. The moving tubes are also provided with a connecting groove. The connecting groove is located at the end of the moving tube away from the drive group. The air pipe is located on the side of the connecting groove close to the drive group. One end of the air pipe is connected to an external air source, and the other end of the air pipe is connected to the connecting groove. A contact point is provided in the connecting groove.

[0010] The vibrating screen sorts and conveys several LEDs, causing them to be vertically conveyed towards the side closest to the detection component. When the LEDs are conveyed to the detection component, they are first conveyed to the shift fork transfer mechanism, which moves them towards the side closest to the detection component. When the LEDs move to the middle of the detection component and the probe mechanism, the probe mechanism powers on the LEDs and lights them up. The detection component then performs spectral detection on the lit LEDs. After the LEDs have been detected, they continue to move under the action of the shift fork transfer mechanism, which conveys them into the conveyor belt. Several LEDs then move along the conveyor belt. When the LEDs that have been spectrally separated are conveyed into the entry slot corresponding to their brightness level, the conveyor belt sends the LEDs into the entry slot, which then conveys them to the placement slot for storage.

[0011] When the probe mechanism contacts and energizes the LED contact point, the drive unit continuously drives the moving tube to move, causing the moving tube to reciprocate along the axis of the probe mechanism. During this reciprocating movement, the moving tube makes contact with and disengages from the LED contact point, thus achieving spectral detection of an LED through a series of contact and disengagement movements. Simultaneously, an external air source sprays air outward through the drive unit and the air pipe inside the moving tube, causing the sprayed gas to move along the edge of the LED contact point. This effectively cleans the LED and suppresses residual adhesive on the LED surface, preventing residual adhesive from entering the moving tube and causing blockage at the contact surface between the moving tube and the LED contact point.

[0012] Preferably, the air pipe comprises a flow pipe, a corrugated pipe, and several branch pipes. The flow pipe is disposed between the corrugated pipe and the branch pipes. The corrugated pipe is connected to the air supply channel in the drive assembly. The branch pipes are connected to the flow pipe and are arranged around the axis of the flow pipe.

[0013] An external gas source is delivered to the bellows through the gas delivery channel in the connecting groove. The gas is then delivered to the flow pipe through the bellows and finally to several branch pipes through the flow pipe. This causes the airflow to be ejected outward from the branch pipes. As the moving pipe moves towards the side closer to the LED under the action of the slide rod, the movement of the slide rod causes the bellows to stretch, so that the bellows continues to deliver gas during the stretching process.

[0014] Preferably, the drive group consists of a drive wheel and two moving groups. The moving groups include a contact wheel, a limiting groove, and a sliding rod. The contact wheel is rotatably connected to the drive wheel. The contact wheel is connected to a sliding rod on one side. The contact wheel and the sliding rod are rotatably connected. The sliding rod is located in the limiting groove and is slidably connected to the limiting groove.

[0015] As the drive wheel rotates, it drives the contact wheel to rotate and lifts the contact wheel. During the lifting process, the contact wheel moves the slide rod, causing it to move along the limiting groove. As the slide rod moves, it moves the moving tube closer to the fork transfer mechanism, allowing the LED antenna to extend into the connecting groove. Simultaneously, the drive wheel's rotation also causes the contact wheel to fall back to its original position, causing it to move the slide rod down along the limiting groove. As the slide rod moves down, it also moves the moving tube down. After the moving tube moves down, the LED antenna disengages from the connecting groove. This reciprocating motion of the moving tube enables the LED to be powered on and illuminated for spectral detection. After the detection is completed, the tube disengages and continues to transport the LED, thus achieving uninterrupted spectral detection.

[0016] Preferably, the fork transplanting mechanism is provided with a conveyor bar on the side near the probe mechanism, and a tapered bar is provided on the side of the conveyor bar opposite to the LED conveying direction. A guide groove is provided between the probe mechanism and the detection mechanism on the conveyor bar, and guide arc plates are provided on both sides of the guide groove. The guide groove and the guide arc plates extend towards the side near the drive group.

[0017] During the process of LEDs being conveyed to the detection assembly via a vibrating screen, the LEDs first enter the fork transfer mechanism and move towards the detection assembly. During this movement, the LEDs encounter a tapered strip, causing the two antennae at the bottom of the LED to separate under the action of the tapered strip, placing the two antennae on opposite sides of the strip. Then, during the conveying process, the LEDs are transported from the tapered strip to the conveyor strip. Subsequently, the LEDs pass through the space between the guide arc plate and the conveyor strip and enter the space between the guide arc plate and the guide groove, where they undergo spectroscopic detection. As the LEDs enter this space, the airflow from the branch pipe flows along the guide arc plate and the guide groove, directing the airflow towards the area where the LEDs are sealed. This achieves both surface cleaning of the LEDs and inhibition of residual adhesive on the LED surface.

[0018] Preferably, a horn tube is provided on the side of the moving tube away from the drive assembly.

[0019] When the moving tube extends towards the LED antenna, it is difficult to directly connect the moving tube to the LED antenna because the LED antenna itself is thin and although there is a conveyor strip to separate the LED antenna. Therefore, a horn tube is set at the end of the moving tube near the LED antenna, so that the LED antenna first encounters the horn tube during the extension process, and moves towards the connecting groove under the action of the horn tube, and finally extends into the connecting groove. This further improves the docking efficiency between the LED antenna and the connecting groove, thereby improving the LED's spectral detection efficiency.

[0020] Preferably, the branch pipe surrounds the connecting groove, and the branch pipe is connected to the horn pipe.

[0021] When the branch pipe sprays air towards the side closest to the LED, because the branch pipe wraps around the connecting groove and is connected to the horn pipe, the gas sprayed from several branch pipes moves along the LED antennae, causing several streams of air to wrap around the LED antennae. During the airflow process, the LED is cleaned, and the airflow blown towards the LED can also suppress the residual glue on the LED, thereby further preventing the residual glue on the LED from entering the connecting groove along the LED antennae and causing the connecting groove to be blocked.

[0022] Preferably, the drive wheel is a cam, and a drive motor is provided on the outer side of the drive wheel, which drives the drive wheel to rotate.

[0023] The drive wheel is set as a cam, so that when the drive motor drives the drive wheel to rotate, the drive wheel drives the contact wheel to move. During the movement of the contact wheel, the slide bar moves axially back and forth along the limit groove, which in turn causes the moving tube to move axially back and forth. During one reciprocating motion of the moving tube, one LED is contacted and energized.

[0024] Preferably, the two moving tubes have different heights.

[0025] Because of the different lengths of the LED antennae, when the moving tube moves towards the LED antennae, it can simultaneously extend the LED antennae into the connecting groove, thereby making contact with the contacts in the connecting groove and energizing the LED beads, thus improving the efficiency of LED spectral detection.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. The probe achieves reciprocating contact with the LED contact point, supporting uninterrupted spectral detection. The drive group in the probe mechanism continuously drives the moving tube to reciprocate along the axis, so that the moving tube completes contact, energization, and detection with the LED contact point in one reciprocating motion, and then disengages. Thus, the spectral detection of one LED is completed in one cycle of contact, lighting, detection, and disengagement, and the next LED can be delivered, realizing continuous and uninterrupted detection operation.

[0028] 2. A horn tube is set on the side of the moving tube away from the drive group. When the moving tube approaches the LED antenna, the thinner LED antenna can enter the horn tube first and move towards the connecting groove under the guidance of the horn tube, and finally extend into the connecting groove to contact the contact point, thereby reducing the difficulty of docking and improving the success rate of antenna insertion and the efficiency of spectral detection.

[0029] 3. One end of the air pipe is connected to an external air source, and the other end is connected to the connecting groove. The external air source sprays gas outward through the air pipe in the drive assembly and the moving tube. The gas flows along the edge of the LED contact, cleaning the LED surface and preventing residual glue from entering the moving tube. This avoids glue clogging the contact surface between the moving tube and the LED contact, reducing the risk of poor contact and blockage of the connecting groove. The air pipe includes a flow pipe, a corrugated pipe, and several branch pipes. The corrugated pipe is connected to the air supply channel in the drive assembly. The flow pipe is located between the corrugated pipe and the branch pipes. The branch pipes are connected to the flow pipe and arranged around the axis of the flow pipe. When the slide bar moves, it can stretch the corrugated pipe, allowing the corrugated pipe to continue supplying gas during the stretching process. This ensures that the air blowing cleaning and glue suppression functions are uninterrupted during the reciprocating movement of the moving tube.

[0030] 4. A conveyor bar is set on the side of the fork transplanting mechanism near the probe mechanism. A tapered bar is set on the side of the conveyor bar opposite to the LED conveying direction. During the movement of the LED, the two antennae at the bottom can be separated by the tapered bar, so that the two antennae are located on both sides of the tapered bar. A guide groove is set between the probe mechanism and the detection mechanism on the conveyor bar. Guide arc plates are set on both sides of the guide groove. The airflow blown out by the branch pipe can flow along the guide arc plates and the guide groove to the LED sealing area, which not only enhances the cleaning effect, but also further suppresses residual glue and improves the detection stability.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1-4 The first embodiment of the present invention shown is a spectrometer for detecting LED lamps, including a vibrating screen 1, a conveying assembly 2 and a detection assembly 3. The detection assembly 3 is located between the vibrating screen 1 and the conveying assembly 2. The conveying assembly 2 includes a plurality of inlet slots 21, a conveying channel 22 and a plurality of placement slots 23. The plurality of inlet slots 21 are symmetrically arranged along the conveying channel 22, and the plurality of placement slots 23 correspond one-to-one with the plurality of inlet slots 21.

[0043] The detection component 3 includes a fork transplanting mechanism 31, a probe mechanism 32, and a detection mechanism. One end of the fork transplanting mechanism 31 is connected to the vibrating screen 1, and the other end of the fork transplanting mechanism 31 is connected to the conveyor 22. The probe mechanism 32 is located below the fork transplanting mechanism 31, and the detection mechanism is located above the fork transplanting mechanism 31. The axis of the probe mechanism 32 and the axis of the detection mechanism are coincident.

[0044] The probe mechanism 32 includes a drive group 33 and two moving tubes 34. The moving tubes 34 are connected to the drive group 33. An air pipe 35 is provided inside the drive group 33 and the moving tubes 34. The moving tubes 34 are also provided with a connecting groove 36. The connecting groove 36 is located at the end of the moving tube 34 away from the drive group 33. The air pipe 35 is located on the side of the connecting groove 36 close to the drive group 33. One end of the air pipe 35 is connected to an external air source, and the other end of the air pipe 35 is connected to the connecting groove 36. A contact point is provided in the connecting groove 36.

[0045] In a specific embodiment of the present invention, the drive group 33 consists of a drive wheel 331 and two moving groups 37. The moving group 37 includes a contact wheel 371, a limiting groove 372 and a sliding rod 373. The contact wheel 371 is rotatably connected to the drive wheel 331. The sliding rod 373 is connected to one side of the contact wheel 371. The contact wheel 371 and the sliding rod 373 are rotatably connected. The sliding rod 373 is located in the limiting groove 372 and is slidably connected to the limiting groove 372.

[0046] In a specific embodiment of the present invention, the drive wheel 331 is a cam, and a drive motor is provided on the outer side of the drive wheel 331, which drives the drive wheel 331 to rotate.

[0047] In a specific embodiment of the present invention, the air pipe 35 comprises a flow pipe 351, a corrugated pipe 352 and a plurality of branch pipes 353. The flow pipe 351 is disposed between the corrugated pipe 352 and the branch pipes 353. The corrugated pipe 352 is connected to the air supply channel in the drive assembly 33. The branch pipes 353 are connected to the flow pipe 351 and are arranged around the axis of the flow pipe 351.

[0048] like Figures 5-8 The second embodiment of the present invention, shown, provides a moving tube 34 and a fork-transfer mechanism 31 that differ from the first embodiment. The difference lies in that a conveying strip 38 is provided at the fork-transfer mechanism 31 in this embodiment. First, a tapered strip 381 is provided at the front end of the conveying strip 38. The tapered strip 381 allows the two antennae of the LED to be separated and moved along the conveying strip 38. When the LED is conveyed between the guide groove 382 and the guide arc plate 383, the airflow output by the air pipe 35 will flow along the guide groove 382 and the guide arc plate 383, so that the airflow directly acts on the LED surface, thereby limiting the flow range of the airflow and avoiding the airflow diffusion that leads to poor cleaning effect on the LED surface and the inability to suppress residual glue from falling. At the same time, a horn tube 39 is provided on the moving tube 34, which further improves the docking efficiency between the connecting groove 36 and the LED antennae. Through the limiting effect of the horn tube 39, the LED antennae first contact the horn tube 39 and are conveyed to the connecting groove 36 under the action of the horn tube 39.

[0049] The specific content is as follows:

[0050] As a specific embodiment of the present invention, the fork transplanting mechanism 31 is provided with a conveying strip 38 on the side near the probe mechanism 32, and a tapered strip 381 is provided on the side of the conveying strip 38 opposite to the LED conveying direction. A guide groove 382 is provided between the probe mechanism 32 and the detection mechanism on the conveying strip 38, and guide arc plates 383 are provided on both sides of the guide groove 382. The guide groove 382 and the guide arc plates 383 extend towards the side near the drive group 33.

[0051] In a specific embodiment of the present invention, a horn tube 39 is provided on the side of the moving tube 34 away from the drive group 33.

[0052] In a specific embodiment of the present invention, the branch pipe 353 surrounds the connecting groove 36, and the branch pipe 353 is connected to the horn pipe 39.

[0053] In a specific embodiment of the present invention, the two movable tubes 34 have different heights.

[0054] Working principle of the invention:

[0055] The vibrating screen 1 screens and conveys several LEDs, causing them to be transported vertically towards the detection component 3. When the LEDs reach the detection component 3, they are first conveyed to the fork transfer mechanism 31. During this process, the LEDs enter the fork transfer mechanism 31 and move towards the detection component. As they move, they encounter a tapered bar 381, causing the two ends of the LED to separate under the action of the tapered bar 381, placing each end of the LED on the tapered bar 381. On both sides, during the conveying process, the LED is conveyed from the tapered strip 381 to the conveyor strip 38. Then, the LED enters the space between the guide arc plate 383 and the guide groove 382 through the space between the guide arc plate 383 and the conveyor strip 38, so that the LED can be split and detected in the space between the guide arc plate 383 and the guide groove 382. When the LED enters the space between the guide arc plate 383 and the guide groove 382, ​​the airflow blown out by the branch pipe 353 will flow along the guide arc plate 383 and the guide groove 382, ​​so that the airflow flows through the guide arc plate 383 and the guide groove 382 to the area where the LED is sealed.

[0056] When the probe mechanism 32 contacts and energizes the LED contact, the drive assembly 33 continuously drives the moving tube 34 to move. During rotation, the drive wheel 331 drives the contact wheel 371 to rotate, and the drive wheel 331 lifts the contact wheel 371. During this lifting process, the contact wheel 371 drives the slide rod 373 to move, causing the slide rod 373 to move along the limiting groove 372. Consequently, during the movement of the slide rod 373, the moving tube 34 is moved towards the side closer to the shift fork transfer mechanism 31, allowing the moving tube 34 to move during its movement. The LED antenna is inserted into the connecting groove 36; when the drive wheel 331 rotates, it also drives the contact wheel 371 to fall back and reset, so that the contact wheel 371 drives the slide bar 373 to move down along the limiting groove 372. When the slide bar 373 moves down, it drives the moving tube 34 to move down. After the moving tube 34 moves down, the LED antenna disengages from the connecting groove 36. Then, the reciprocating motion of the moving tube 34 realizes the process of the LED being powered on and lit for spectral detection. After the detection is completed, it disengages and continues to be transported, thus realizing uninterrupted spectral detection.

[0057] When the moving tube 34 extends toward the LED antenna, since the LED antenna itself is thin, and although the conveyor strip 38 separates the LED antenna, it is difficult to directly connect the moving tube 34 with the LED antenna. Therefore, a horn tube 39 is set at the end of the moving tube 34 near the LED antenna, so that the LED antenna first encounters the horn tube 39 during the extension process, and moves toward the connecting groove 36 under the action of the horn tube 39, and finally extends into the connecting groove 36.

[0058] Because of the different lengths of the LED antennae, when the moving tube 34 moves toward the LED antennae, it can simultaneously extend the LED antennae into the connecting groove 36, thereby simultaneously contacting the contacts in the connecting groove 36 and realizing the power supply and lighting of the LED beads.

[0059] The moving tube 34 reciprocates along the axis of the probe mechanism 32. During the reciprocating movement, the moving tube 34 contacts and disengages from the LED antenna, thereby performing spectral detection on an LED in a reciprocating motion of contact and disengagement. At the same time as the moving tube 34 moves, an external air source is ejected outward through the drive group 33 and the air pipe 35 inside the moving tube 34, causing the ejected gas to move along the edge of the LED antenna.

[0060] An external gas source is delivered to the bellows 352 through the gas delivery channel in the connecting groove 36, and then to the flow pipe 351 through the bellows 352. Finally, the gas is delivered to several branch pipes 353 through the flow pipe 351, so that the airflow is ejected outward from the several branch pipes 353. Since the moving pipe 34 will move towards the side closer to the LED under the action of the slide rod 373, the slide rod 373 will stretch the bellows 352 when it moves, so that the bellows 352 continues to deliver gas during the stretching process.

[0061] When the branch pipe 353 sprays air towards the side close to the LED, since the branch pipe 353 wraps around the connecting groove 36 and is connected to the horn pipe 39, the gas sprayed by several branch pipes 353 will move along the LED antenna, so that several streams of air will wrap around the LED antenna. During the airflow, the LED is cleaned, and the airflow blown towards the LED can also suppress the residual glue on the LED.

[0062] The LEDs that have completed the testing continue to move under the action of the fork transfer mechanism 31, so that the LEDs are transported by the fork transfer mechanism 31 to the conveyor 22. Subsequently, several LEDs move along the conveyor 22. When the LEDs after beam splitting are transported to the entry slot 21 corresponding to the brightness level, the conveyor 22 sends the LEDs into the entry slot 21, so that the LEDs are transported through the entry slot 21 to the placement slot 23 for storage.

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
