Description

Technical Field

[0001] This invention relates to the field of testing device technology, specifically an automatic COB performance testing device. Background Technology

[0002] In the automated performance testing process of COB light sources, the current production process usually requires first inspecting the front of the light source (using an image sensor), then flipping the light source using a flipping mechanism, and finally inspecting the back of the light source.

[0003] During the flipping process of the light source, it is usually necessary to add an extra cylinder or clamping component to clamp and position the light source, which makes the entire flipping mechanism very complex and makes it impossible to achieve accurate synchronization of flipping, clamping and releasing. In addition, the added cylinder or clamping component is prone to causing unstable clamping force or damage during clamping. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic COB performance testing device to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic COB performance testing device, comprising a chamber, a tilting mechanism, a first conveying mechanism, and a testing mechanism;

[0006] The chamber is the internal space of the rack;

[0007] The flipping mechanism includes a support plate and a clamping mechanism. The support plate is installed on both sides of the first conveying mechanism. The support plate is provided with a track with varying depth. A flipping frame is installed between the two support plates. An adsorption mechanism is installed on the flipping frame. The flipping frame is provided with a storage chamber for accommodating a light source. The flipping frame is connected to the output end of a drive source. The drive source is installed on the first conveying mechanism.

[0008] The clamping mechanism includes a clamping plate and a guide member. The clamping plate is slidably installed in the storage chamber. One end of the guide member is installed on the clamping plate, and the other end of the guide member slides in the track. An elastic member is connected between the clamping plate and the flipping frame.

[0009] The detection mechanism is located on both sides of the support plate and is installed on the first conveying mechanism.

[0010] The track includes a clamping section, a stopping section, and a relaxing section connected in sequence. The depth of the clamping section is set to increase, the depth of the stopping section is set to be constant, and the depth of the relaxing section is set to decrease.

[0011] The guide member includes a guide post and a rolling element. The guide post is mounted on the clamping plate, and the rolling element is mounted on the guide post. The rolling element slides within a clamping section, a dwell section, and a release section.

[0012] A feeding mechanism is installed on one side of the first conveying mechanism, and a discharging mechanism is installed on the other side of the first conveying mechanism;

[0013] The feeding mechanism includes a feeding line installed in the chamber, a lifting module and a pushing component. A discharge platform is installed above the feeding line. A lifting frame and a discharge cylinder are sequentially installed on the sliding end of the lifting module. The pushing component is installed on the feeding line.

[0014] The feeding mechanism is installed on the floor.

[0015] The pusher is a pusher cylinder, which is electrically connected to the control system. A pusher rod is installed on the telescopic rod of the pusher cylinder, and one end of the pusher rod is flat. When the lifting module moves the material box upwards by a set distance, the pusher cylinder drives the pusher rod to insert into the material box, pushing out multiple COB light sources in the material box in sequence.

[0016] The feeding mechanism includes a cutting mechanism and a waste discharge mechanism;

[0017] The cutting mechanism includes a first cutting roller, a second cutting roller, and a collecting mechanism installed on the chamber;

[0018] The first cutting roller is located above the second cutting roller. Both the first and second cutting rollers are rotatably mounted on the chamber. Both the first and second cutting rollers are connected to the output end of a power source, which is mounted on the chamber.

[0019] The collection mechanism is installed indoors.

[0020] The power source includes a servo motor, three drive gears, and a transmission chain. The servo motor is mounted on the ceiling, and the three drive gears are respectively mounted on the first cutting roller, the second cutting roller, and the output end of the servo motor. The two drive gears on the first and second cutting rollers mesh with each other, and the drive gears on the first cutting roller and the servo motor are connected through the transmission chain. The servo motor drives the drive gears on it to rotate, and the drive gears on the servo motor drive the first and second cutting rollers to rotate through the transmission chain.

[0021] The first and second cutting rollers are respectively provided with mutually cooperating cutting grooves and cutting teeth, and the cutting teeth are electrically connected to the control system through an electric slip ring.

[0022] The collection mechanism includes a vibrating roller, a pressing component, a collection cover, and a distributing mechanism. Multiple vibrating rollers are rotatably mounted on the chamber and connected to each other by belts. The longitudinal section of the vibrating roller is polygonal, and the vibrating roller is connected to the output end of a power source.

[0023] The pressing component and the collecting cover are located on both sides of the multiple vibrating rollers, and both the pressing component and the collecting cover are installed on the chamber.

[0024] The material distribution mechanism is connected to the collection hood.

[0025] A driven gear is installed on the vibrating roller. The driven gear meshes with the transmission chain. When the first and second cutting rollers rotate, the transmission chain simultaneously drives multiple vibrating rollers to rotate through the driven gear. Since the longitudinal section of the vibrating roller is polygonal, the polygonal section vibrating roller generates mechanical vibration through the alternating contact between the edges and the plane when rotating, causing the COB light source to shake and separate and fall into the collection hood by gravity.

[0026] The material distribution mechanism includes a vibration mechanism and a storage mechanism;

[0027] The vibration mechanism includes a vibration box and a vibration plate. The inlet of the vibration box is connected to a collection hood. The bottom of the vibration box is provided with a slag discharge port and a material discharge port. The vibration box is connected to the output end of a vibration element, and the vibration element is installed on the chamber.

[0028] The vibrating plate is inclinedly arranged inside the vibrating box, and the vibrating plate is provided with a vibrating groove. The slag discharge port and the material discharge port are located on both sides of the vibrating plate.

[0029] The storage mechanism is connected to the discharge port.

[0030] The storage mechanism includes a receiving hopper and a rotating disk. Multiple receiving hoppers are provided, and the multiple receiving hoppers are detachably mounted on the rotating disk. The rotating disk is connected to the output end of a rotation source, which is mounted on the floor and electrically connected to the control system.

[0031] The testing mechanism is installed on the first conveying mechanism via a transplanting mechanism;

[0032] The detection mechanism includes an image sensor and a lighting lamp. The image sensor is mounted on the transplanting mechanism, and the lighting lamp is mounted on the ceiling.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. Automatic clamping and releasing during the flipping process. A track with varying depth is provided on the support plate, consisting of a clamping section, a dwell section, and a release section. One end of the guide is connected to the clamping plate, and the other end slides within the track. As the flipping frame rotates, the rolling element sequentially passes through the clamping, dwell, and release sections. The increasing depth of the clamping section forces the clamping plate to clamp the light source; the dwell section maintains the clamping state; and the decreasing depth of the release section, combined with the elastic element's return to its original position, releases the light source. The flipping, clamping, and releasing functions are simultaneously achieved through a single drive source, making the entire detection device simpler and more compact. This solves the problem of requiring separate power control for clamping during the flipping process and addresses the issue of unstable clamping force leading to light source slippage or damage.

[0035] 2. Automated and orderly feeding of COB light sources improves detection efficiency. The feeding line transports a cassette containing multiple COB light sources to the lifting frame. The lifting module moves the cassette upwards a predetermined distance each time. The pushing cylinder pushes the top COB light source in the cassette onto the first conveyor line. The first conveyor line transports the COB light sources until all COB light sources in the cassette are discharged. At this point, the discharging cylinder pushes the empty cassette onto the discharging platform, realizing the sequential discharge of multiple COB light sources from the cassette. This significantly reduces labor intensity and reduces the likelihood of empty cassettes or multiple light sources being discharged at once, solving the problem of low detection efficiency. One end of the pushing rod is flat, resulting in more even force when pushing the light source and preventing scratches during the pushing process. Attached Figure Description

[0056] 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.

[0057] Example: Figures 1-14 As shown, this invention provides a technical solution for an automatic COB performance testing device, including a chamber 1, a flipping mechanism 3, a first conveying mechanism 4, and a testing mechanism 5. The first conveying mechanism 4 is a belt conveyor line used to stably convey the COB light source, and the belt conveyor line is installed on the chamber 1; the chamber 1 is the internal space of the frame; the flipping mechanism 3 includes a support plate 31 and a clamping mechanism 32. The support plate 31 is installed on both sides of the first conveying mechanism 4, and a track 311 with varying depth is provided on the support plate 31. A flipping frame 33 is installed between the two support plates 31, and an adsorption mechanism 34 is installed on the flipping frame 33. The adsorption mechanism 34 is a suction cup. The tray is connected to the negative pressure system. The flipping frame 33 is provided with a storage chamber for accommodating the light source. The flipping frame 33 is connected to the output end of the drive source 35, which is installed on the first conveying mechanism 4. The clamping mechanism 32 includes a clamping plate 321 and a guide member 322. The clamping plate 321 is slidably installed in the storage chamber. One end of the guide member 322 is installed on the clamping plate 321, and the other end of the guide member 322 slides in the track 311. An elastic member, such as a spring or an elastic plate, is connected between the clamping plate 321 and the flipping frame 33. The detection mechanism 5 is located on both sides of the support plate 31 and is installed on the first conveying mechanism 4.

[0058] The detection mechanism 5 is installed on the first conveying mechanism 4 via a transfer mechanism. The transfer mechanism is a horizontal module installed on the first conveying mechanism 4. The horizontal module drives the image sensor 51 to move so that the image sensor 51 can detect different positions of the COB light source. The control system judges the performance of the COB light source based on the detection data. The detection mechanism 5 includes an image sensor 51 and a lighting lamp 52. The image sensor 51 is installed on the transfer mechanism and is used to detect defects, flaws and stains of the COB light source. The lighting lamp 52 is installed on the chamber 1.

[0059] When the first conveying mechanism 4 conveys the COB light source to the first inspection station, the image sensor 51 and the lighting lamp 52 of the first inspection station start working to inspect the front of the COB light source.

[0060] After the front detection of the COB light source is completed, the first conveying mechanism 4 continues to move the COB light source to the storage chamber of the flipping frame 33. At this time, the first conveying mechanism 4 feeds back the displacement data of the COB light source to the control system. The control system uses the adsorption mechanism 34 to adsorb the COB light source. After the adsorption mechanism 34 adsorbs the COB light source, the control system uses the drive source 35 to drive the flipping frame 33 to rotate 180 degrees. The flipping frame 33 drives the adsorbed COB light source to rotate 180 degrees, so that the back of the COB light source is placed on the first conveying mechanism 4 with the back facing up. The first conveying mechanism 4 continues to convey the COB light source with the back facing up to the second detection station. The image sensor 51 and the lighting lamp 52 on the second detection station start working to detect the back of the COB light source. The control system judges the performance of the COB light source based on the visual data of the front and back of the COB light source.

[0061] The track 311 includes a clamping section 3111, a dwell section 3112, and a release section 3113 connected in sequence. The depth of the clamping section 3111 is set to increase, the depth of the dwell section 3112 is set to be constant, and the depth of the release section 3113 is set to decrease. The guide member 322 includes a guide post 3221 and a rolling member 3222. The guide post 3221 is mounted on the clamping plate 321, and the rolling member 3222 is mounted on the guide post 3221. The rolling member 3222 slides within the clamping section 3111, the dwell section 3112, and the release section 3113. The rolling member 3222 is a ball or a roller.

[0062] During the process of the drive source 35 driving the tilting frame 33 to rotate, the tilting frame 33 drives the clamping plate 321 to move accordingly. The clamping plate 321 drives the rolling element 3222 to move accordingly through the guide post 3221, so that the rolling element 3222 slides in the clamping section 3111, the dwell section 3112 and the release section 3113 in sequence.

[0063] When the rolling element 3222 slides in the clamping section 3111, as the depth of the clamping section 3111 gradually increases, the clamping section 3111 forces the rolling element 3222 to move into the storage chamber. The rolling element 3222 drives the clamping plate 321 to clamp the COB light source through the guide post 3221, and the guide post 3221 stretches the elastic element at the same time.

[0064] When the rolling element 3222 is in the dwell section 3112, since the depth of the dwell section 3112 is constant, the rolling element 3222 does not move when it slides in the dwell section 3112. At this time, the clamping plate 321 always clamps the COB light source.

[0065] When the rolling element 3222 slides within the relaxation section 3113, the depth of the relaxation section 3113 gradually decreases. At this time, the elastic element is released, and the elastic element pulls the guide post 3221 away from the COB light source. The guide post 3221 drives the clamping plate 321 away from the COB light source. The clamping plate 321 releases the COB light source and places it on the first conveying mechanism 4.

[0066] The first conveying mechanism 4 has a feeding mechanism 2 installed on one side and a discharging mechanism 6 installed on the other side. The feeding mechanism 2 includes a feeding line 21, a lifting module 22 and a pushing component 23 installed on the chamber 1. The feeding line 21 is a feeding conveyor line used to stably convey the material box. The material box stores multiple COB light sources. A discharge platform 211 is installed above the feeding line 21. A lifting frame 221 and a discharge cylinder 222 are installed sequentially on the sliding end of the lifting module 22. The pushing component 23 is installed on the feeding line 21 and is a pushing cylinder. The discharging mechanism 6 is installed on the chamber 1.

[0067] The pusher component 23 is a pusher cylinder, which is electrically connected to the control system. A pusher rod is installed on the telescopic rod of the pusher cylinder, and one end of the pusher rod is flat. When the lifting module 22 drives the material box to move upward by a set distance, the pusher cylinder drives the pusher rod to insert into the material box, pushing out multiple COB light sources in the material box in sequence.

[0068] The staff places the material box storing COB light sources on the feeding line 21 so that the material box is conveyed into the lifting frame 221. At this time, the control system drives the lifting frame 221 to move upward through the lifting module 22. The lifting frame 221 drives the material box to move upward to the pushing station. The COB light source at the top of the material box is facing the pushing rod. At this time, the pushing component 23 drives the pushing rod to insert into the material box. The pushing component 23 pushes the COB light source in the material box to the first conveying mechanism 4 through the pushing rod.

[0069] After the pusher pushes the COB light source in the material box to the first conveying mechanism 4, the pusher 23 drives the pusher to retract. Then, the lifting module 22 continues to move the material box upward by a set distance so that the new COB light source is facing the pusher. The pusher 23 continues to drive the pusher to push the new COB light source to the first conveying mechanism 4. The above operation is repeated to push multiple COB light sources in the material box onto the first conveying mechanism 4.

[0070] When all the COB light sources in the material box are pushed onto the first conveying mechanism 4, the pusher 23 retracts, the discharge cylinder 222 starts working, and the discharge cylinder 222 pushes the empty material box to the discharge platform 211 to realize the discharge of the empty material box.

[0071] The feeding mechanism 6 includes a cutting mechanism 61 and a waste discharge mechanism 62. The cutting mechanism 61 includes a first cutting roller 611, a second cutting roller 612, and a collection mechanism 613 mounted on the chamber 1. The first cutting roller 611 is located above the second cutting roller 612. Both the first cutting roller 611 and the second cutting roller 612 are rotatably mounted on the chamber 1. Both the first cutting roller 611 and the second cutting roller 612 are connected to the output end of a power source 614, which is mounted on the chamber 1. The collection mechanism 613 is mounted on the chamber 1. The waste discharge mechanism 62 consists of two linear modules and a clamp. The two linear modules drive the clamp to remove the defective COB light source and place it in the waste area, thereby realizing the discharge of waste.

[0072] The power source 614 includes a servo motor, three drive gears, and a transmission chain. The servo motor is mounted on chamber 1. The three drive gears are respectively mounted on the first cutting roller 611, the second cutting roller 612, and the output end of the servo motor. The two drive gears on the first cutting roller 611 and the second cutting roller 612 mesh with each other. The drive gear on the first cutting roller 611 and the drive gear on the servo motor are connected through the transmission chain. The servo motor drives the drive gear on it to rotate, and the drive gear on the servo motor drives the first cutting roller 611 and the second cutting roller 612 to rotate through the transmission chain.

[0073] When the first conveying mechanism 4 conveys the COB light source to the cutting station, the control system drives the first cutting roller 611 to rotate forward and the second cutting roller 612 to rotate in reverse through the power source 614. The first cutting roller 611 and the second cutting roller 612 drive the COB light source to move to one side. The cutting groove on the first cutting roller 611 and the cutting teeth on the second cutting roller 612 cooperate with each other to cut the COB light source, so that the large COB light source is cut into the required size.

[0074] The first cutting roller 611 and the second cutting roller 612 are respectively provided with mutually cooperating cutting grooves and cutting teeth. The cutting teeth are electrically connected to the control system through an electric slip ring. The fixed end of the electric slip ring is installed on the chamber 1, and the rotating end of the electric slip ring is connected to the cutting teeth through a wire. The control system energizes the cutting teeth through the electric slip ring and the wire, so that the cutting teeth generate heat and form thermal cutting to avoid debris flying.

[0075] The collection mechanism 613 includes a vibrating roller 6131, a pressing component 6132, a collection cover 6133, and a distributing mechanism 615. Multiple vibrating rollers 6131 are rotatably mounted on the chamber 1 and are connected by belts. The longitudinal section of the vibrating rollers 6131 is polygonal, and the vibrating rollers 6131 are connected to the output end of the power source 614. The pressing component 6132 and the collection cover 6133 are located on both sides of the multiple vibrating rollers 6131, and are both mounted on the chamber 1. The pressing component 6132 is a pressing cylinder that pushes the COB light source downward into the collection cover 6133 after the COB light source is cut. The distributing mechanism 615 is connected to the collection cover 6133.

[0076] A driven gear is installed on the vibrating roller 6131. ​​The driven gear meshes with the transmission chain. When the first cutting roller 611 and the second cutting roller 612 rotate, the transmission chain simultaneously drives multiple vibrating rollers 6131 to rotate through the driven gear. Since the longitudinal section of the vibrating roller 6131 is polygonal, the polygonal section of the vibrating roller 6131 generates mechanical vibration through the alternating contact between the edges and the plane when rotating, causing the COB light source to shake and separate and fall into the collection cover 6133 by gravity.

[0077] The material distribution mechanism 615 includes a vibration mechanism and a storage mechanism. The vibration mechanism includes a vibration box 6151 and a vibration plate 6152. The inlet of the vibration box 6151 is connected to the collection hood 6133. The bottom of the vibration box 6151 is provided with a slag discharge port and a material discharge port. The vibration box 6151 is connected to the output end of the vibration element 6153. The vibration element 6153 is installed on the chamber 1. The vibration element 6153 can be a vibration cylinder, an electromagnetic vibration component, etc., used to realize the vibration of the vibration box 6151 and the vibration plate 6152, thereby realizing the separation of debris and COB light source. The vibration plate 6152 is inclinedly arranged in the vibration box 6151. The vibration plate 6152 is provided with a vibration groove. The slag discharge port and the material discharge port are located on both sides of the vibration plate 6152. The storage mechanism is connected to the material discharge port.

[0078] After the COB light source is cut, the cut COB light source and debris fall into the collection hood 6133. The COB light source and debris enter the vibration box 6151 through the collection hood 6133. The vibration element 6153 drives the vibration box 6151 to vibrate. The COB light source is discharged from the discharge port along the surface of the vibration plate 6152 after vibration, while the debris passes through the vibration groove on the vibration plate 6152 and is discharged from the slag discharge port, thus realizing the separation of debris and COB light source.

[0079] The storage mechanism includes a receiving hopper 6154 and a rotating disk 6155. Multiple receiving hoppers 6154 are provided, and multiple receiving hoppers 6154 are detachably installed on the rotating disk 6155. The rotating disk 6155 is connected to the output end of a rotation source 6156. The rotation source 6156 is installed on chamber 1 and is electrically connected to the control system.

[0080] When the COB light source is discharged from the outlet, it enters the receiving hopper 6154 through the outlet to achieve COB light source storage.

[0081] When the receiving hopper 6154 is full, the control system drives the rotating disk 6155 to rotate at a certain angle through the rotating source 6156 so that the new receiving hopper 6154 is facing the discharge port.

[0082] Working principle: The operator places the material box containing COB light sources on the feeding line 21. The feeding line 21 transports the material box to the lifting frame 221. At this time, the lifting module 22 drives the lifting frame 221 to move upward to the pushing station, so that the uppermost COB light source in the material box is directly facing the pushing rod of the pushing component 23. The pushing component 23 drives the flat pushing rod to insert into the material box and push the COB light source onto the first conveying mechanism 4. Through the cooperation of the lifting module 22 and the pushing component 23, multiple COB light sources in the material box are pushed onto the first conveying mechanism 4 in sequence. The first conveying mechanism 4 drives the COB light sources to the first inspection station, the flipping station, the second inspection station, the waste discharge station, and the cutting station in sequence.

[0083] When the COB light source is delivered to the first inspection station, the image sensor 51 and the lighting lamp 52 of the first inspection station are activated to inspect the front of the COB light source.

[0084] After the front detection is completed, the first conveying mechanism 4 conveys the COB light source to the storage chamber. The control system starts the adsorption mechanism 34 to adsorb the COB light source and controls the drive source 35 to drive the flipping frame 33 to rotate 180 degrees. The flipping frame 33 drives the adsorbed COB light source to flip together, so that the back of the COB light source faces up and is placed back on the first conveying mechanism 4.

[0085] The COB light source with its back facing up is delivered to the second inspection station by the first conveying mechanism 4. The image sensor 51 and the lighting lamp 52 at the second inspection station inspect the back of the COB light source. The control system judges the performance of the COB light source based on the visual data from the front and back.

[0086] After the front and back of the COB light source are inspected, the control system determines whether the performance of the COB light source meets the requirements based on the inspection data. When the COB light source does not meet the requirements, the first conveying mechanism 4 moves the non-compliant COB light source to the waste discharge station. The control system grabs the non-compliant COB light source through the waste discharge mechanism 62 and moves it to the waste area to achieve the discharge of defective products or waste.

[0087] When both the front and back sides of the COB light source pass inspection, the first conveying mechanism 4 sends the COB light source into the cutting station. The power source 614 drives the first cutting roller 611 to rotate forward and the second cutting roller 612 to rotate in reverse. The electric heating effect of the cutting teeth performs thermal cutting on the light source. The cut light source and debris fall into the collection cover 6133 and enter the vibration box 6151 of the material distribution mechanism 615. The vibration element 6153 drives the vibration box 6151 and the inclined vibration plate 6152 to vibrate. The debris passes through the vibration groove on the vibration plate 6152 and is discharged from the slag discharge port. The finished COB light source slides along the vibration plate 6152 to the discharge port and falls into the receiving hopper 6154, realizing the storage of the finished COB light source.

[0088] 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.
