Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead production, and in particular to a testing and sorting device for LED lamp beads. Background Technology

[0002] The testing and sorting device is a specialized device for quality inspection and classification of LED beads. Its main function is to accurately sort, test, and classify LED beads based on parameters such as photoelectric characteristics, appearance, and size.

[0003] When using a sorting machine to test and sort LED beads, the LED beads are conveyed to a turntable, and then the controller starts the turntable to rotate. At the same time, the laser scanning camera is activated to scan and test the LED beads conveyed to the turntable. After the test is completed, the qualified or unqualified LED beads are pushed away to the corresponding guide rack by an electric telescopic rod to separate them. Because the turntable is rotating, the LED beads may be thrown off the surface of the turntable due to inertia, which will affect the sorting efficiency.

[0004] To solve the above problems, an electric clamping unit is now installed on the turntable to clamp the LED beads. The electric clamping unit needs to be equipped with power lines and control lines. The numerous wirings are complicated and the cost of use and maintenance is also high. Utility Model Content

[0005] The technical problem this utility model aims to solve is that the electric clamping unit needs to be equipped with power lines and control lines, and the complex wiring and high maintenance costs result from the numerous lines.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: an LED lamp bead testing and sorting device, including a sorting machine, a first conveyor belt and a second conveyor belt on one side of the sorting machine, limit rods symmetrically arranged on one side of the sorting machine, one side of the limit rods closely attached to one side of the second conveyor belt, a turntable rotatably mounted on one side of the sorting machine, a laser scanning camera positioned between the turntable and the second conveyor belt on one side of the sorting machine, a controller on one side of the sorting machine, a bracket symmetrically fixedly mounted on one side of the sorting machine, an electric telescopic rod fixedly mounted on one side of the bracket, a push plate fixedly mounted at one end of the electric telescopic rod, a guide frame symmetrically arranged on one side of the sorting machine and the bottom of the turntable, and several limiting devices on one side of the turntable. The limiting devices can use slots and two limiting blocks to limit and fix the LED lamp beads conveyed to the turntable, preventing them from being thrown out by inertia during rotation and transfer.

[0007] The aforementioned components achieve the following effect: When using the sorting machine to test and sort LED beads, the LED beads are placed on the first conveyor belt for transport. Under the limitation of the limiting rod, they are transported to the second conveyor belt and arranged for further transport. The movement of both the first and second conveyor belts is controlled by the controller on the sorting machine. The drive motor on the starting side drives the rotating shaft, thereby causing the first and second conveyor belts to rotate on the sorting machine and transport the LED beads. The second conveyor belt transports the LED beads to the turntable, where they are limited and fixed by the limiting device. Then, the controller controls the turntable to rotate, and at the same time, the laser scanning camera scans and tests the LED beads transported to the turntable to inspect their appearance. The data is uploaded to the controller for analysis and displayed on the screen on one side. After analysis, the controller issues an instruction to rotate the turntable to a certain angle, so that the electric telescopic rod at the corresponding position drives the push plate to push the qualified or unqualified LED beads away to the corresponding guide frame, separating them and completing the testing and sorting process.

[0008] Preferably, the limiting device includes two limiting blocks, a plurality of slots are provided on one side of the turntable, and sliding grooves are provided on both sides of the inner wall of the slots. The two limiting blocks are symmetrically slidably installed in the inner walls of the two sliding grooves, and the cross-section of the limiting block is trapezoidal; a spring, wherein the two ends of the spring are respectively fixedly installed on one side of the limiting block and one side of the inner wall of the sliding groove.

[0009] The effect achieved by the above-mentioned components is as follows: by setting a limiting device, when the LED beads are conveyed to the turntable by the second conveyor belt, the bottom of the LED beads will be locked between the two limiting blocks in the slot. The limiting blocks are pushed to slide to a certain position in both ends of the inner wall of the slide, causing the spring to contract. At the same time, the spring's reset action will limit the LED beads. In this way, when the turntable rotates and conveys the LED beads, the LED beads will not be thrown out and damaged, reducing production costs and avoiding affecting sorting efficiency.

[0010] Preferably, a protective block is fixedly installed on one side of the limiting block, and the protective block is made of sponge material.

[0011] The effect achieved by the above components is that by setting up protective blocks, the wear between the limit blocks and the LED beads can be reduced, and the surface of the LED beads can be prevented from being scratched.

[0012] Preferably, a plurality of rollers are rotatably mounted on one side of the limiting block, and the plurality of rollers are arranged at equal intervals.

[0013] The effect achieved by the above components is that by setting rollers, when the LED beads are conveyed to the slot by the second conveyor belt, the contact friction between the LED beads and the limiting blocks can be reduced, making it easier for them to be locked between the two limiting blocks.

[0014] Preferably, the limiting device further includes a limiting telescopic rod, wherein the outer surface of the limiting telescopic rod is installed through the inner wall of the spring, and both ends are respectively fixedly installed on one side of the limiting block and one side of the inner wall of the slide groove.

[0015] The effect achieved by the above components is that by setting the limiting telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use.

[0016] Preferably, a collection device is symmetrically arranged on one side of the sorting machine. The collection device includes a placement frame, one side of which is fixedly installed on one side of the sorting machine, and a groove is formed on one side of the placement frame; and a collection box, wherein the bottom of the collection box is inserted into the inner wall of the groove.

[0017] The effect achieved by the above components is as follows: by setting up a collection device, before sorting, the collection box can be placed in the groove on the placement rack, so that the collection box is located directly below the flow guide rack, which makes it convenient for the flow guide rack to export and collect the LED beads, which is convenient for subsequent processing.

[0018] Preferably, handle blocks are fixedly installed on both sides of the collection box, and the cross-section of the handle blocks is arc-shaped.

[0019] The effect achieved by the above components is that by setting handle blocks, the contact area on both sides of the collection box can be increased, making it easier to manually grasp and move it.

[0020] Preferably, a reinforcing rod is fixedly installed at the bottom of the placement frame, and one side of the reinforcing rod is fixedly installed on one side of the sorting machine.

[0021] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the placement frame and the sorting machine can be increased, making the connection more secure and stable.

[0022] The beneficial effects of this utility model are:

[0023] By setting a limiting device, when the LED beads are conveyed to the turntable by the second conveyor belt, the bottom of the LED beads will be locked between two limiting blocks in the slot. The limiting blocks will be pushed to slide to a certain position in both ends of the inner wall of the slide, causing the spring to contract. At the same time, the spring's reset action will limit the LED beads. The mechanical clamping method requires no additional wiring or program debugging. Moreover, the mechanical clamping method only requires checking the spring force during operation and maintenance, without the need for additional debugging of the electrical control program. Debugging is quick and convenient, saving debugging costs. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Figure 1-4 The LED bead testing and sorting device shown includes a sorting machine 1. A first conveyor belt 4 is arranged on one side of the sorting machine 1, and a second conveyor belt 13 is arranged on one side of the sorting machine 1. Limiting rods 5 are symmetrically arranged on one side of the sorting machine 1, with one side of the limiting rods 5 closely attached to one side of the second conveyor belt. A turntable 12 is rotatably mounted on one side of the sorting machine 1. A laser scanning camera 6 (model CV-X4000) is arranged on one side of the sorting machine 1 between the turntable 12 and the second conveyor belt 13. A controller 7 is provided on one side of the sorting machine 1. A bracket 8 is symmetrically fixedly installed on one side of the sorting machine 1. An electric telescopic rod 9 is fixedly installed on one side of the bracket 8. A push plate 10 is fixedly installed at one end of the electric telescopic rod 9. A guide frame 11 is symmetrically arranged on one side of the sorting machine 1 and the bottom of the turntable 12. Several limiting devices 2 are provided on one side of the turntable 12. The limiting devices 2 can limit and fix the LED beads conveyed to the turntable 12 through the slot 21 and two limiting blocks 24 to prevent them from being thrown out by inertia during rotation and transfer. When using the sorting machine 1 to test and sort LED beads, the LED beads are placed on the first conveyor belt 4 for transport. Under the control of the limiting rod 5, they are transported to the second conveyor belt 13 and arranged for further transport. The movement of both the first and second conveyor belts 4 and 13 is controlled by the controller 7 on the sorting machine 1. The drive motor on the starting side rotates the shaft, thus rotating the first and second conveyor belts 4 and 13 on the sorting machine 1, transporting the LED beads. The second conveyor belt 13 transports the LED beads to the turntable 12, where they are limited by the limiting device 2. The LEDs are fixed in place, and then the controller 7 controls the rotation of the turntable 12. Simultaneously, the laser scanning camera 6 scans and tests the LED beads conveyed to the turntable 12, inspecting their appearance. The data is uploaded to the controller 7 for analysis and displayed on a screen on one side. After analysis, an instruction is issued to rotate the turntable 12 to a certain angle, allowing the electric telescopic rod 9 at the corresponding position to drive the push plate 10 to push the qualified or unqualified LED beads onto the corresponding guide frame 11, thus sorting them and completing the testing and sorting process. It should be noted that the controller 7 and the laser scanning camera 6 are mature technologies and equipment in the prior art; their internal structure, connection methods, and principles will not be elaborated upon further.

[0033] Figure 2 and Figure 3The limiting device 2 shown includes two limiting blocks 24. A plurality of slots 21 are provided on one side of the turntable 12. Slide grooves 22 are provided on both sides of the inner wall of each slot 21. The two limiting blocks 24 are symmetrically slidably installed in the inner walls of the two slide grooves 22. The cross-section of the limiting blocks 24 is trapezoidal. A spring 23 is also included, with its two ends fixedly installed on one side of the limiting block 24 and one side of the inner wall of the slide groove 22, respectively. When the second conveyor belt 13 conveys the LED beads to the turntable 12, the bottom of the LED beads is engaged between the two limiting blocks 24 in the slots 21, pushing the limiting blocks 24 to slide towards both ends in the inner wall of the slide groove 22 to a certain position. This causes the spring 23 to contract. Simultaneously, the restoring action of the spring 23 limits the LED beads. Therefore, when the turntable 12 rotates and conveys the LED beads, the LED beads will not be thrown out and damaged, reducing production costs and avoiding affecting sorting efficiency.

[0034] Figure 2 and Figure 3 A protective block 25, made of sponge material, is fixedly installed on one side of the limiting block 24. By setting the protective block 25, wear between the limiting block 24 and the LED bead can be reduced, preventing scratches on the LED bead surface (at the same time, the sponge protective block 25 can deform to better clamp the LED bead, preventing it from being thrown out by inertia). Several rollers 26 are rotatably installed on one side of the limiting block 24, arranged at equal intervals. By setting the rollers 26, when the second conveyor belt 13 conveys the LED bead to the slot 21, the contact friction between the LED bead and the limiting block 24 can be reduced, facilitating its insertion between the two limiting blocks 24. The limiting device 2 also includes a limiting telescopic rod 27, the outer surface of which is installed through the inner wall of the spring 23, and both ends are fixedly installed on one side of the limiting block 24 and one side of the inner wall of the slide groove 22, respectively. By setting the limiting telescopic rod 27, the inner wall of the spring 23 can be supported and reinforced, making it less prone to damage during use.

[0035] Figure 4 The sorting machine 1 shown has a collection device 3 symmetrically arranged on one side. The collection device 3 includes a placement frame 31, one side of which is fixedly installed on one side of the sorting machine 1, and a groove 32 is formed on one side of the placement frame 31; and a collection box 33, the bottom of which is inserted into the inner wall of the groove 32. Before sorting, the collection box 33 can be placed in the groove 32 on the placement frame 31, so that the collection box 33 is directly below the flow guide frame 11, which facilitates the flow guide frame 11 to guide and collect the LED beads for subsequent processing.

[0036] Figure 4The collection box 33 shown has handle blocks 34 fixedly installed on both sides, and the cross-section of the handle blocks 34 is arc-shaped. By setting the handle blocks 34, the contact area on both sides of the collection box 33 can be increased, making it easier to manually grasp and move it. A reinforcing rod 35 is fixedly installed at the bottom of the placement frame 31, and one side of the reinforcing rod 35 is fixedly installed on one side of the sorting machine 1. By setting the reinforcing rod 35, the connection area between the placement frame 31 and the sorting machine 1 can be increased, making the connection more secure and stable.

[0037] Working principle: Before sorting, the collection box 33 can be placed in the groove 32 on the placement rack 31, so that the collection box 33 is directly below the flow guide rack 11, which makes it convenient for the flow guide rack 11 to export and collect the LED beads for later processing. When using the sorting machine 1 to test and sort LED beads, the LED beads are placed on the first conveyor belt 4 for transport. Under the control of the limiting rod 5, they are transported to the second conveyor belt 13 and arranged for further transport. The movement of both the first and second conveyor belts 4 and 13 is controlled by the controller 7 on the sorting machine 1. The drive motor on the starting side rotates the shaft, thus rotating the first and second conveyor belts 4 and 13 on the sorting machine 1 to transport the LED beads. When the second conveyor belt 13 transports the LED beads to the turntable 12, the bottom of the LED bead is engaged between the two limiting blocks 24 in the slot 21. This pushes the limiting blocks 24 to slide towards both ends in a certain position within the inner wall of the slide groove 22, causing the spring 23 to contract. Simultaneously, the spring 23 returns to its original position. The function is to limit the LED beads, so that when the turntable 12 rotates and conveys the LED beads, the LED beads will not be thrown out and damaged, reducing production costs and avoiding affecting sorting efficiency. Then, the controller 7 controls the turntable 12 to rotate, and at the same time, the laser scanning camera 6 is activated to scan and test the LED beads conveyed to the turntable 12, inspect their appearance, and upload the data to the controller 7 for analysis and display on the screen on one side. After analysis, the controller 12 is instructed to rotate the tested LED beads to a certain angle, so that the electric telescopic rod 9 at the corresponding position can drive the push plate 10 to push the qualified or unqualified LED beads away to the corresponding guide frame 11, sorting them apart and completing the testing and sorting process.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
