The device is driven by an electromagnet, and a set of matching positioning optical fibers are provided at the end of the lower separation mechanism and at the corresponding position of the upper separation mechanism; the main turntable module is located on one side of the implantation mechanism, including an indexing turntable with several suction nozzles, the suction nozzles cooperating with the implantation mechanism, and also includes a pre-test detection mechanism and a residual material detection mechanism; the positioning module cooperates with the indexing turntable in the main turntable module; the test module is located on one side of the main turntable module, the test module includes a set of test probes, the test probes are respectively located on both sides of the suction nozzle, and the integrating sphere module is located directly above the suction nozzle corresponding to the test probe.
[0003] While existing LED sorting and color sorting machines can perform testing and sorting of LED products at room temperature, they cannot meet the requirement of testing and sorting LED products within a specified temperature range after heating. For example, for LED products used in the automotive industry, such as car headlights, the operating temperature of the LEDs can be very high due to vehicle operation or direct sunlight when the car is parked in an open parking lot. To ensure that the LEDs operate normally at high temperatures, it is usually required that they be tested and sorted within a specified temperature range after heating. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an LED fully automatic feeding disc-type spectral sorting machine and its working method, which aims to solve the technical problem that the existing LED spectral sorting machines cannot achieve the purpose of testing and sorting LED products within a specified temperature range after heating.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An LED fully automatic feeding disc-type spectral sorting and color separation machine includes a frame, a feeding module, a control system, and a test assembly module. The test assembly module includes a workbench, a feeding separation module, a test module, a turntable module, a discharge module, and a heating module.
[0007] The workbench is mounted on the frame, and a feeding channel is provided on the workbench. The workbench is also provided with multiple discharge holes, which are distributed around the circumference of the workbench.
[0008] The feeding module is mounted on the frame and is used to transport the LED products to be tested into the feeding channel;
[0009] The turntable module includes a disc-shaped turntable and a drive unit. The disc-shaped turntable is attached to the surface of the worktable and can rotate relative to the worktable. The outer edge of the disc-shaped turntable has several circumferentially matrix-arranged receiving grooves. When the receiving grooves rotate to the position of the corresponding feeding channel, they communicate with the feeding channel. The drive unit is set on the worktable and is used to drive the disc-shaped turntable to rotate.
[0010] The feeding separation module is set on the workbench and is used to feed the LED products entering the feeding channel into each of the receiving slots one by one; the heating module is set on the workbench and controlled by the control system, and the heating module is used to heat the LED products in the receiving slots to a preset temperature.
[0011] The test module is set on the workbench and controlled by the control system. The test module is used to test the LED product in the receiving tank after the LED product in the receiving tank is heated to a preset temperature, and to feed the test data of the test module back to the control system.
[0012] The discharge module is set on the workbench. The discharge module includes multiple discharge components that are controlled by the control system. Each discharge component corresponds to a discharge hole. The discharge components are used to push the LED products in the receiving groove after testing into the discharge holes.
[0013] The control system sorts LED products based on test data and controls the corresponding discharge components to push the tested LED products in the receiving slots into the corresponding discharge holes based on the sorting information.
[0014] Furthermore, the heating module includes an upper heating base, a heating element, and a cover plate. The upper heating base has an arc-shaped structure and is concentric with the disc-shaped turntable. The upper heating base is fixed to a fixing ring on the surface of the workbench. The fixing ring is concentric with the disc-shaped turntable and located on the periphery of the disc-shaped turntable. The upper heating base is located above the disc-shaped turntable. An accommodating groove is formed inside the upper heating base, and the heating element is placed in the accommodating groove. The cover plate seals the accommodating groove. The heat generated by the heating element is transferred through the upper heating base to heat the LED product in the accommodating groove.
[0015] Furthermore, the heating module also includes a lower heating base and a heating tube. The lower heating base is disposed below the workbench, and the heating tube is disposed on the lower heating base for heating the lower heating base. The heat generated by the heating tube is transferred to the workbench through the lower heating base.
[0016] Furthermore, the upper heating base and / or lower heating base are equipped with temperature sensing wires controlled by the control system.
[0017] Furthermore, the feeding module includes a hopper, a feeding vibratory feeder, and a straight-feed feeding track. The outlet of the hopper is connected to the feeding vibratory feeder. A straight feeding trough is provided on the straight-feed feeding track. The inlet of the straight feeding trough is connected to the outlet of the feeding vibratory feeder. The outlet of the straight feeding trough is connected to the feeding channel on the workbench. A heating channel is provided on the straight-feed feeding track. The heating channel is located below the straight feeding trough and extends along the axial direction of the straight-feed feeding track. A heating element is provided in the heating channel along its axial direction.
[0018] Furthermore, the upper surface of the workbench is provided with multiple arc-shaped hollow grooves, which are distributed around the circumference of the workbench and located around the fixed ring. Multiple heat dissipation grooves are provided at the bottom of the arc-shaped hollow grooves, and heat dissipation covers are provided on the arc-shaped hollow grooves.
[0019] Furthermore, a slot is formed on the inner edge of the fixing ring, and the receiving groove communicates with the slot when rotated to the position of the slot. A baffle is sealed on the slot. The test module includes a test probe device disposed below the slot. The inner edge of the baffle is aligned with the inner edge of the fixing ring. The inner ring surface of the fixing ring abuts against the disc-shaped turntable. The disc-shaped turntable can rotate relative to the fixing ring. A vacuum suction port is provided on the bottom surface of the baffle. The vacuum suction port is used to adsorb the LED product in the receiving groove until it abuts against the inner edge of the baffle.
[0020] Furthermore, it also includes a receiving box, which is provided with multiple connection ports, each corresponding to a multiple discharge hole. The discharge hole is connected to the connection port through a discharge guide tube. A silicone buffer structure is provided inside the connection port. The receiving box is provided with multiple receiving boxes, each receiving box corresponding to a connection port. The receiving boxes are drawn in and out of the receiving box.
[0021] Furthermore, the discharge assembly includes an air blowing unit. An installation groove is formed on the upper surface of the worktable along the radial direction of the disc-shaped turntable, corresponding to the position of the discharge hole. The air blowing unit is installed in the installation groove. Multiple air blowing grooves are formed on the bottom surface of the disc-shaped turntable. The multiple air blowing grooves correspond to and communicate with multiple receiving grooves one by one. The air blowing grooves extend radially along the disc-shaped turntable. The air blowing grooves are coaxial with the receiving grooves. The air blowing unit is controlled by the control system. The air blowing unit is used to blow the LED products in the receiving grooves into the discharge hole.
[0022] A working method for an LED fully automatic feeding disc-type spectral sorting and color separation machine includes the following steps:
[0023] S1. Place the LED product to be tested in the feeding module, which will then feed it into the feeding channel. When one LED product enters the feeding channel, the feeding separation module will block the next LED product from entering the feeding channel. At this time, the drive unit will drive the disc-shaped turntable to rotate. When a receiving slot on the disc-shaped turntable rotates to correspond with the feeding channel, the feeding separation module will push one LED product in the feeding channel into a receiving slot on the disc-shaped turntable. This cycle will be repeated to achieve the feeding action one by one.
[0024] S2. After the LED product enters the receiving slot on the disc-shaped turntable, the disc-shaped turntable continues to rotate, and the heating module heats the LED product in the receiving slot to the preset temperature range.
[0025] S3. After the LED product in the receiving tank is heated to the preset temperature range, the disc-shaped turntable continues to rotate. When the LED product in the receiving tank on the disc-shaped turntable rotates to the station of the corresponding test module, the test module tests the LED product in the receiving tank to make the LED product light up.
[0026] S4. The test data from the test module is fed back to the control system. The control system sorts the LED products according to the test data, and controls the corresponding discharge component to push the LED products in the receiving slot into the corresponding discharge hole according to the sorting information.
[0027] Compared with the prior art, the significant advantages of the present invention are:
[0028] In operation, the fully automatic LED feeding disc-type spectral sorting machine of this invention feeds the LED products to be tested into the feeding channel via a feeding module. Once one LED product enters the feeding channel, a feeding separation module prevents the next LED product from entering. At this time, the drive unit drives the disc-shaped turntable to rotate. When a receiving slot on the disc-shaped turntable rotates to correspond with and communicate with the feeding channel, the feeding separation module pushes an LED product from the feeding channel into a receiving slot on the disc-shaped turntable. This cycle repeats, achieving sequential feeding. After being placed in the receiving tank, the disc-shaped turntable continues to rotate, and the heating module heats the LED products in the receiving tank to a preset temperature range. Meanwhile, the disc-shaped turntable continues to rotate. When the LED products in the receiving tank on the disc-shaped turntable rotate to the corresponding test module's station, the test module tests the LED products in the receiving tank, and the LED products are lit up. Simultaneously, the test module feeds the test data back to the control system, which sorts the LED products according to the test data and controls the corresponding discharge component to push the tested LED products in the receiving tank into the corresponding discharge holes. Therefore, the fully automatic LED feeding disc-type color sorting machine of the present invention can perform testing and sorting of LED products after they have been heated to a specified temperature range, thereby meeting the product testing requirements and overcoming the technical deficiency of existing color sorting machines that cannot achieve the requirement of testing and sorting LED products after they have been heated to a specified temperature range.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0056] In this invention, unless otherwise expressly specified and limited, the first feature "above" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them.
[0057] Please refer to Figure 1 - Figure 23 The present invention provides an LED fully automatic feeding disc-type spectral sorting and color separation machine, including a frame 1, a feeding module 2, a control system 3, a test assembly module 4, and a receiving box module 5.
[0058] Reference Figure 1 , Figure 2 and Figure 3 The feeding module 2 is mounted on the frame 1 and is used to transport the LED products to be tested into the feeding channel 401. Specifically, the feeding module 2 includes a hopper 20, a feeding vibratory feeder 21 controlled by the control system 3, and a straight feeding track 22. The outlet of the hopper 20 is connected to the feeding vibratory feeder 21. A straight feeding groove 220 is provided on the straight feeding track 22, which extends along the axial direction of the straight feeding track 22. The inlet of the straight feeding groove 220 is connected to the outlet of the feeding vibratory feeder 21. It can be understood that after the LED products to be tested enter the feeding vibratory feeder 21 through the hopper 20, they enter the straight feeding groove 220 of the straight feeding track 22 and enter the test assembly module 4 along the straight feeding groove 220.
[0059] It should be noted that the feeding module 2 adopts the feeding module structure of a Mini-LED embedded feeding and color sorting machine disclosed in the prior art (publication number: CN116329135A), which will not be described in detail here. The difference is that the feeding vibratory feeder 21 in this embodiment is a heated vibratory feeder, as described in reference [reference missing]. Figure 4 A heating channel 221 is provided on the straight feed track 22. The heating channel 221 is located below the straight feed chute 220 and extends axially along the straight feed track 22. A heating element (not shown) is fixed inside the heating channel 221 along its axial direction. In this way, the LED product under test can be heated during the process of conveying the LED product under test into the test assembly module 4. The heating element in this embodiment is a tubular structure.
[0060] Additionally, refer to Figure 2 and Figure 3 Heat dissipation racks 23 are fixed on both sides of the straight feed track 22. The heat dissipation racks 23 can dissipate the heat on the straight feed track 22 and play a heat dissipation role.
[0061] Reference Figure 2 , Figure 5 and Figure 13The test assembly module 4 includes a workbench 40, a feeding and separating module, a testing module, a turntable module 43, a discharging module 44, and a heating module. The workbench 40 is fixed to the frame 1. A feeding channel 401 is provided on the workbench 40, coaxial with a linear feeding chute 220. The inlet of the feeding channel 401 communicates with the outlet of the linear feeding chute 220. Furthermore, the workbench 40 also has multiple discharge holes 408. In this embodiment, six discharge holes 408 are provided, but not limited to a certain number, and the multiple discharge holes 408 are distributed circumferentially along the workbench 40. Additionally, a cooling fan is fixed below the workbench 40 for cooling the test assembly module 4.
[0062] Reference Figure 5 , Figure 13 , Figure 16 and Figure 17 The turntable module 43 includes a disc-shaped turntable 430 and a drive unit 431. The disc-shaped turntable 430 is attached to the surface of the worktable 40 and can rotate relative to the worktable 40. The outer edge of the disc-shaped turntable 430 has several circumferentially arranged receiving slots 4301. In this embodiment, 50 receiving slots 4301 are provided, but this is not limited to. The receiving slots 4301 penetrate the upper and lower surfaces of the disc-shaped turntable 430 and extend radially along the disc-shaped turntable 430. When the receiving slots 4301 rotate to the position corresponding to the feeding channel 401, they communicate with the feeding channel 401. The drive unit 431 is mounted on the worktable 40 and is a drive motor used to drive the disc-shaped turntable 430 to rotate. In this embodiment, the rotating disc-shaped turntable 430 rotates clockwise.
[0063] Reference Figure 5 , Figure 6 , Figure 8 and Figure 13 The feeding and separating module is mounted on the worktable 40 and is used to feed the LED products entering the feeding channel 401 one by one into the respective receiving slots 4301. Specifically, the feeding and separating module includes a separating mechanism 41 and a rotary blowing device. The separating mechanism 41 is equipped with a push rod 410, which is driven by an electromagnet to realize the upward and downward movement of the push rod 410. When the push rod 410 is raised into the through hole in the feeding channel 401, it blocks the LED products in the linear feeding groove 220 from entering the feeding channel 401. When the push rod 410 is in the downward state, the LED products in the linear feeding groove 220 can enter the feeding channel 401. The separating mechanism 41 adopts an existing structure, such as the structure of the separating lower mechanism in a Mini-LED implantable feeding and color sorting machine disclosed in (publication number: CN116329135A), which will not be described in detail here.
[0064] Reference Figure 5 , Figure 6 and Figure 8 The rotary blowing device includes a rotary cylinder 411, a fixed base 412, a connecting rod 413, a reference optical fiber 414, and a connecting block 415. The fixed base 412 is fixed on the worktable 40 and is used to drive the connecting rod 413 to rotate. The connecting block 415 is fixed on the connecting rod 413. The transmitting end 4141 of the reference optical fiber 414 is fixed vertically on the connecting block 415, and the receiving end 4140 of the reference optical fiber 414 is fixed on the separation mechanism 41. The feeding channel 401 also has a through hole for the receiving end 4140 of the reference optical fiber 414 to pass through. The connecting block 415 has an air blowing hole 4150, and the opening of the air blowing hole 4150 is inclined to the feeding chute. The reference optical fiber 414 is used to detect whether there are LED products in the feeding channel 401. When the reference fiber optic cable 414 detects an LED product in the feeding channel 401, the push rod 410 rises to block the next LED product from entering the feeding channel 401. When the reference fiber optic cable 414 detects no LED product in the feeding channel 401, the push rod 410 descends, and the gas ejected from the air blowing hole 4150 blows the LED product in the feeding chute into the feeding channel 401. In this way, the LED products in the feeding channel 401 can be fed one by one into each receiving tank 4301, realizing the feeding action one by one.
[0065] It should be noted that the rotary blowing device in this embodiment also uses an existing structure, such as the structure of the rotary blowing device in the fully automatic LED disc-type spectral sorting machine and its working method disclosed in the prior art patent (publication number: CN104741326B), which will not be described in detail here.
[0066] Reference Figure 1 The heating module is mounted on the workbench 40 and controlled by the control system 3. The heating module is used to heat the LED products in the receiving tank 4301 to a preset temperature. Specifically, refer to... Figure 5 , Figure 6 , Figure 10 - Figure 12 and Figure 19 - Figure 21 The heating module includes an upper heating element 45 and a lower heating element 46. The upper heating element 45 includes an upper heating base 450, a heating element 451, and a cover plate 452. The upper heating base 450 has an arc-shaped structure and is concentric with the disc-shaped turntable 430. The upper heating base 450 is fixed to a fixing ring 402 on the upper surface of the worktable 40. The fixing ring 402 is concentric with the disc-shaped turntable 430 and located on the periphery of the disc-shaped turntable 430. The upper heating base 450 is located above the disc-shaped turntable 430. A receiving groove is formed in the upper heating base 450, and the heating element 451 is fixed in the receiving groove. The cover plate 452 covers the receiving groove. The heat generated by the heating element 451 when it is powered on is transferred through the upper heating base 450 to heat the LED product in the receiving groove 4301.
[0067] Of course, the upper heating base 450 and the lower heating base 460 are provided with a first temperature sensing line 453 controlled by the control system 3. The first temperature sensing line 453 is used to detect the temperature of the upper heating base 450. The first temperature sensing line 453 is connected to a temperature controller (not shown). The temperature controller is controlled by the control system 3. When the temperature sensed by the first temperature sensing line 453 reaches the set value, the heating element 451 will stop emitting heat. Otherwise, it will continue to heat up, ensuring that the temperature is maintained within the set value range.
[0068] Since the upper heating base 450 has an arc-shaped structure and is concentric with the disc-shaped turntable 430, the heating element 451 and the receiving groove 4501 in this embodiment also adopt an arc-shaped structure. The arc-shaped receiving groove 4501 and the heating element 451 are also concentric with the disc-shaped turntable 430. This allows the upper heating base 450 to be heated evenly, while also increasing the heat transfer area of the upper heating base 450, so as to quickly heat the LED product in the receiving groove 4301 to the preset temperature.
[0069] The lower heating assembly 46 includes a lower heating base 460 and a heating tube 461. The lower heating base 460 is fixed below the worktable 40, and the heating tube 461 is disposed on the lower heating base 460 for heating the lower heating base 460. The heat generated by the heating tube 461 is transferred to the worktable 40 through the lower heating base 460. Since the disc-shaped turntable 430 is in contact with the upper surface of the worktable 40, and the receiving groove 4301 extends through the upper and lower surfaces of the disc-shaped turntable 430, the heat transferred through the worktable 40 can heat the LED product in the receiving groove 4301.
[0070] To ensure even heating, the lower heating base 460 is equipped with multiple heating tubes 461 and a second temperature sensing line 462 controlled by the control system 3. The second temperature sensing line 462 is used to detect the temperature on the heating base. Similarly, the required temperature value is set in the temperature controller. When the temperature sensed by the second temperature sensing line reaches the set value, the heating tubes 461 stop emitting heat continuously; otherwise, they continue to heat up, ensuring that the temperature is maintained at the set value.
[0071] Of course, in order to detect the temperature of the LED product in the receiving tank 4301, a temperature sensor (not shown) can be embedded in the side wall of the receiving tank 4301 to detect the temperature of the LED product in the receiving tank 4301.
[0072] In this embodiment, the upper heating component 45 and the lower heating component 46 are combined to heat and maintain the temperature while the disc-shaped turntable 430 rotates, ensuring that the LED product can reach the required temperature range during testing.
[0073] Reference Figure 5Because the workbench 40 gets very hot, to address this issue, multiple arc-shaped perforated slots 4050 are formed on the upper surface of the workbench 40. These slots are distributed circumferentially around the workbench 40 and are located around the fixing ring 402. Multiple heat dissipation grooves 406 are formed at the bottom of each arc-shaped perforated slot 405, and a heat dissipation cover 405 is installed on top of each slot. Thus, the perforated heat dissipation cover 405 and the multiple heat dissipation grooves 406 within the arc-shaped perforated slots 4050 slow down temperature diffusion and increase heat dissipation around the workbench 40. Furthermore, to prevent burns, a heat-insulating protective cover 407 is installed above the surface of the workbench 40.
[0074] The test module is mounted on the workbench 40 and controlled by the control system 3. The test module is used to test the LED products in the receiving tank 4301 after they have been heated to a preset temperature, and feeds back the test data from the test module to the control system 3. The test module includes a data acquisition unit and a test probe device 420. The data acquisition unit is controlled by the control system 3 and uses a high-temperature resistant color sensor (not shown). The color sensor can be mounted and fixed on the workbench 40 or on the bottom of the upper heating base 450 to acquire the light parameters (such as light intensity and color) of the illuminated LED product. The test probe device 420 can adopt the structure of the test probe device 420 in a fully automatic surface-mount LED disc-type spectrophotometer and its working method disclosed in existing patent (publication number: CN104741326B), which will not be described in detail here. Multiple test modules can be set in this embodiment to improve testing efficiency. The aforementioned lower heating component 46 is also provided between the test probe devices 420 of two test modules.
[0075] To ensure that every LED product is tested at the same location when it arrives at the testing station of the testing probe device 420, refer to... Figure 13 , Figure 14 and Figure 18A slot 4020 is formed on the inner ring edge of the fixing ring 402. The slot 4020 is T-shaped. When the receiving groove 4301 rotates to the position of the slot 4020, the receiving groove 4301 communicates with the slot 4020. Of course, a baffle 4021 is sealed on the slot 4020. The baffle 4021 is a T-shaped plate. The test probe device 420 of the test module is set below the slot 4020. The inner edge of the baffle 4021 is aligned with the inner ring edge of the fixing ring 402. The inner ring surface of the fixing ring 402 abuts against the disc-shaped turntable 430. The disc-shaped turntable 430 can rotate relative to the fixing ring 402. A vacuum suction port 4022 is provided on the bottom surface of the baffle 4021. The vacuum suction port 4022 is used to adsorb the LED product in the receiving groove 4301 until it abuts against the inner ring edge of the baffle 4021. Therefore, it can be understood that when the LED product in the receiving tank 4301 rotates to the test position of the test probe device 420, the vacuum suction port 4022 adsorbs the LED product in the receiving tank 4301 and positions it against the inner ring edge of the baffle 4021. At this time, the electromagnet of the test probe device 420 pushes the probe upward, and the LED product is lit up for testing. At the same time, the acquisition unit collects the light parameters of the lit LED product and feeds the light parameters back to the control system 3.
[0076] The discharge module 44 is mounted on the workbench 40. The discharge module 44 includes a discharge seat 441 and multiple discharge components 440, each controlled by the control system 3. Each discharge component 440 corresponds to a discharge hole. The discharge components 440 are used to push the tested LED products from the receiving groove 4301 into the discharge holes. When the control system 3 sorts the LED products according to the collected test data, it controls the corresponding discharge component 440 to operate based on the sorting information, thereby pushing the tested LED products from the receiving groove 4301 into the corresponding discharge holes.
[0077] Specifically, refer to Figure 1 , Figure 5 - Figure 7 and Figure 15The discharge assembly 440 includes an air blowing unit 4401 and a position sensor 4402. A mounting groove 403 is formed on the upper surface of the worktable 40 along the radial direction of the disc-shaped turntable 430, corresponding to the position of the discharge hole 408. The air blowing unit 4401 is installed in the mounting groove 403. Multiple air blowing grooves 4302 are formed on the bottom surface of the disc-shaped turntable 430. These multiple air blowing grooves 4302 correspond one-to-one with multiple receiving grooves 4301 and communicate with each other. The air blowing grooves 4302 extend radially along the disc-shaped turntable 430 and are coaxial with the receiving grooves 4301. The air blowing unit 4401 is controlled by the control system 3. The air blowing unit 4401 uses a solenoid valve and is used to blow LED products from the receiving grooves 4301 into the discharge hole 408. The discharge seat 441 is fixed to the upper surface of the fixing ring 402. Multiple position sensors 4402 are provided, each corresponding to a different discharge hole 408. The position sensors 4402 are fixed on the discharge seat 441. The detection laser of the position sensor 4402 can pass through the discharge seat to detect whether there is an LED product in the receiving groove 4301. Therefore, the control system 3 analyzes and classifies the collected test data. When an LED product in a receiving groove 4301 reaches the corresponding designated discharge hole, the position sensor 4402 determines that the LED product in the receiving groove 4301 is in position. Then, the control system 3 controls the air blowing unit 4401 to blow the LED product in the receiving groove 4301 into the designated discharge hole. After the LED product is blown into the discharge hole, the disc-shaped turntable 430 continues to operate.
[0078] Reference Figure 2 , Figure 10 , Figure 22 and Figure 23The receiving box module 5 includes a receiving box 50, which has multiple connection ports 501. Each connection port 501 corresponds to a discharge hole, and the discharge holes communicate with the connection ports 501 via a discharge guide tube (a transparent rubber tube). A silicone cushioning structure is installed inside each connection port 501. Multiple receiving boxes 51 are installed inside the receiving box 50, each corresponding to and communicating with a connection port 501. The receiving boxes 51 are drawer-type and move in and out of the receiving box 50. Therefore, after being blown into the discharge hole, the LED product falls along the discharge guide tube into the connection port 501, is cushioned by the silicone cushioning structure, and then enters the receiving box 51, preventing damage from impact. Furthermore, multiple insertion slots 5011 are provided along the circumference of the connection port 501 to secure the discharge guide tube, preventing it from detaching from the connection port 501 due to deformation caused by environmental changes. In addition, a magnet and a sensor switch 52 are installed behind the receiving box 50. When the receiving box 51 is pushed into the receiving box 50, the magnet on the receiving box 50 will attract and fix the receiving box 51. At this time, the sensor switch 52 will sense that there is a receiving box in the receiving box 50. When the receiving box 51 is pushed out, the receiving box 51 will detach from the magnet, and the equipment will light up a yellow light and enter the stop state.
[0079] This invention also provides a working method for an LED fully automatic feeding disc-type spectral sorting and color separation machine, comprising the following steps:
[0080] S1. Place the LED product to be tested in the feeding module 2, and the feeding module 2 will transport it into the feeding channel 401. When an LED product enters the feeding channel 401, the feeding separation module will block the next LED product from entering the feeding channel 401. At this time, the driving unit 431 will drive the disc-shaped turntable 430 to rotate. When a receiving slot 4301 on the disc-shaped turntable 430 rotates to correspond to and communicate with the feeding channel 401, the feeding separation module will push an LED product in the feeding channel 401 into a receiving slot 4301 on the disc-shaped turntable 430. This cycle will be repeated to realize the feeding action one by one.
[0081] S2. After the LED product enters the receiving groove 4301 on the disc-shaped turntable 430, the disc-shaped turntable 430 continues to rotate, and the heating module heats the LED product in the receiving groove 4301 to the preset temperature range.
[0082] S3. When the LED product in the receiving tank 4301 is heated to the preset temperature range, the disc-shaped turntable 430 continues to rotate. When the LED product in the receiving tank 4301 on the disc-shaped turntable 430 rotates to the station of the corresponding test module, the test module tests the LED product in the receiving tank 4301 to make the LED product light up.
[0083] S4. The test data of the test module is fed back to the control system 3. The control system 3 sorts the LED products according to the test data, and controls the corresponding discharge component 440 to move according to the sorting information, so as to push the LED products in the receiving groove 4301 after testing into the corresponding discharge hole.
[0084] In step S1, LED products are supplied to the feeding module 2. The material on the vibratory feeder is vibrated and arranged by the vibratory feeder, and then conveyed one by one to the linear feed chute 220 of the linear feed track 22. During the conveying of LED products in the linear feed track 22, the heating element on the linear feed track 22 is energized and generates heat, which is then transferred to the LED products in the linear feed chute 220. When an LED product enters the feeding channel 401 on the worktable 40, Then, the push rod 410 is raised to prevent the next LED product from entering the feeding channel 401. At this time, the drive unit 431 drives the disc-shaped turntable 430 to rotate clockwise. When a receiving slot 4301 on the disc-shaped turntable 430 rotates to correspond to and communicate with the feeding channel 401, the gas blown out by the air blowing hole 4150 on the connecting block 415 pushes an LED product in the feeding channel 401 into a receiving slot 4301 on the disc-shaped turntable 430. This cycle is repeated to realize the feeding action one by one.
[0085] In step S2, after the LED product enters the receiving groove 4301 on the disc-shaped turntable 430, the disc-shaped turntable 430 continues to rotate, and the upper heating component 45 and the lower heating component 46 of the heating module work, so that the disc-shaped turntable 430 rotates while heating and keeping the temperature, ensuring that the LED product can reach the required temperature range during testing.
[0086] In step S3, after the LED product in the receiving tank 4301 is heated to the preset temperature range, the disc-shaped turntable 430 continues to rotate. When the LED product in the receiving tank 4301 on the disc-shaped turntable 430 rotates to the station of the corresponding test module, the vacuum suction port 4022 on the baffle 4021 generates negative pressure, adsorbing the LED product in the receiving tank 4301 and positioning it against the inner ring edge of the baffle 4021. At this time, the test probe device 420 of the test module tests the LED product in the receiving tank 4301. The electromagnet of the test probe device 420 pushes the probe upward, and the LED product is lit up for testing. At the same time, the acquisition unit collects the test data (light parameters) of the lit LED product and feeds the test data back to the control system 3.
[0087] In step S4, after the control system 3 receives the test data, it sorts and analyzes the LED products based on the test data. Based on the sorting information, it controls the corresponding discharge component 440 to push the tested LED products in the receiving groove 4301 into the corresponding discharge hole. Specifically, when the LED product in the receiving groove 4301 reaches the position of the designated discharge hole, the position sensor 4402 feeds back information to the control system 3. The control system 3 then controls the air blowing unit 4401 to blow the LED product in the receiving groove 4301 into the discharge hole. At this point, the position sensor 4402 detects that there are no more LED products in the receiving groove 4301, and the disc-shaped turntable 430 continues to operate.
[0088] When the LED product is blown into the discharge hole, it falls along the discharge guide tube into the connection port 501 on the receiving box module 5. After being buffered by the silicone buffer structure in the connection port 501, the falling speed is slowed down before entering the receiving box 51 of the receiving box 50, thus avoiding damage to the LED product.
[0089] In summary, when the LED fully automatic feeding disc-type spectral sorting machine of the present invention is in use, the LED product to be tested is conveyed into the feeding channel 401 through the feeding module 2. When an LED product enters the feeding channel 401, the push rod 410 of the feeding separation module lifts up to prevent the next LED product from entering the feeding channel 401. At this time, the drive unit 431 drives the disc-shaped turntable 430 to rotate. When a receiving groove 4301 on the disc-shaped turntable 430 rotates to correspond to and communicate with the feeding channel 401, the air blown out by the air blowing hole 4150 of the feeding separation module pushes an LED product in the feeding channel 401 into a receiving groove 4301 on the disc-shaped turntable 430. This cycle is repeated to realize the feeding action one by one. When an LED product enters the disc-shaped turntable 430, the feeding unit 431 drives the disc-shaped turntable 430 to rotate ... After the LED product is placed in the receiving slot 4301 on the 30, the disc-shaped turntable 430 continues to rotate, and the heating module heats the LED product in the receiving slot 4301 to the preset temperature range. At this time, the disc-shaped turntable 430 continues to rotate. When the LED product in the receiving slot 4301 on the disc-shaped turntable 430 rotates to the station of the corresponding test module, the test probe device 420 of the test module tests the LED product in the receiving slot 4301, causing the LED product to light up. The acquisition unit of the test module collects the test data and feeds it back to the control system 3. The control system 3 analyzes and classifies the LED product according to the collected test data, and controls the corresponding discharge component 440 to move according to the sorting information, thereby pushing the tested LED product in the receiving slot 4301 into the corresponding discharge hole. Therefore, it can be seen that the LED fully automatic feeding disc-type spectral sorting machine of the present invention can perform testing and sorting of LED products when they are heated to a certain specified temperature range, thereby meeting the testing requirements of the products and overcoming the technical defect that the existing spectral sorting machine cannot achieve the requirement of testing and sorting of LED products when they are heated to a certain specified temperature range.
