Description

Technical Field

[0001] This utility model belongs to the field of LED lamp bead production technology, and in particular relates to an LED lamp bead light color distribution detection device. Background Technology

[0002] With the rapid development of LED lighting and display technologies, the application scenarios of LED chips are becoming increasingly widespread, and their color consistency has become a core indicator determining product quality. In the mass production of LED chips, it is necessary to detect abnormal color distribution and eliminate defective products to ensure that the color parameters of the same batch of chips meet the standards.

[0003] Currently, the standard procedure for testing the color distribution of LED beads is to insert each LED bead into the test fixture and then visually judge the color of each bead. However, this method is difficult to meet the testing needs of large-scale production, and the test results are easily affected by factors such as the operator's subjective judgment and fluctuations in ambient light, resulting in inconsistent testing standards, high false detection rate and false negative rate, which seriously affects the stability of product quality.

[0004] Therefore, it is necessary to design an LED bead color distribution detection device to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of conventional LED bead color detection, which relies on manual insertion and visual judgment of each bead, resulting in low efficiency, inconsistent standards, susceptibility to subjective and environmental factors, and high false negative and false negative rates, this utility model provides an LED bead color distribution detection device.

[0006] This utility model is achieved through the following technical means: an LED bead color distribution detection device, comprising a cabinet, a partition, a cabinet door, an observation window, a rotating shaft, a support plate, a slide rail, an LED test seat, a guide rod, a spring, a clamping plate, an inclined block, a protrusion, a detection camera, and a controller. The cabinet is divided into two spaces by the partition. A cabinet door is rotatably installed at the front of the cabinet. An observation window is embedded and fixed inside the cabinet door. A rotating shaft is fixed to the side of the cabinet door and the observation window near the inside of the cabinet. A support plate is rotatably installed at one end of each rotating shaft. An LED test seat is placed on each support plate. The bottom of the cabinet... Two parallel slide rails are fixed to the top of each partition. The support plate slides with the corresponding two slide rails. A guide rod is fixed to both sides of each support plate. A clamp is slidably installed on the outside of each guide rod. The clamp slides with the corresponding support plate. A spring is sleeved on the outside of each guide rod. The two ends of the spring are connected to the corresponding support plate and the corresponding clamp, respectively. A protrusion is fixed to the top of each clamp. Two inclined blocks are fixed to the left and right inner walls of the cabinet. Detection cameras are installed at the top of the cabinet and the bottom of the partition. A controller is installed on the right side of the cabinet. The detection cameras are electrically connected to the controller.

[0007] Preferably, it also includes a second guide rod, a second spring, and a buffer plate. Two symmetrically arranged second guide rods are slidably arranged on each clamping plate. A buffer plate is fixed between one end of two adjacent second guide rods. A second spring is sleeved on the outside of each second guide rod. The two ends of the second spring are respectively connected to the corresponding clamping plate and the corresponding buffer plate.

[0008] As a preferred option, it also includes a handle, with a handle fixed to the other side of the cabinet door away from the inside of the cabinet, and the handle is equipped with an anti-slip sleeve.

[0009] Preferably, the device also includes baffles, with a baffle fixed to the front of each support plate, and the front side of the LED test base maintaining contact with the rear side of the corresponding baffle.

[0010] Preferably, the LED test socket is a dedicated LED test socket.

[0011] Preferably, the bump and the corresponding bevel are kept at the same height.

[0012] The beneficial effects are: 1. Through the ingenious cooperation of cabinet door, pivot, support plate, slide rail, clamp, protrusion and inclined block, the entire process of automatically clamping the LED test holder and accurately delivering the LED test holder to the bottom of the detection camera can be completed by simply rotating the cabinet door. This achieves standardization of the detection process, greatly improves detection efficiency, effectively avoids false detection and missed detection caused by factors such as manual operation and ambient light, and ensures the stability of product quality and the objectivity and consistency of test results.

[0013] 2. By setting up guide rod two, spring two and buffer plate, the rigid clamping of the clamping plate is transformed into the buffered clamping of the buffer plate, which prevents the LED test socket from being damaged due to excessive clamping force. Attached Figure Description

[0021] Example: An LED lamp bead color distribution detection device, such as Figures 1-6As shown, the system includes a cabinet 1, a partition 11, a cabinet door 2, a handle 21, an observation window 22, a pivot 3, a support plate 31, a slide rail 32, a baffle 33, an LED test base 34, a guide rod 4, a spring 41, a clamp 42, a wedge 45, a protrusion 47, a detection camera 5, and a controller 6. The interior of the cabinet 1 is divided into two spaces by a fixedly connected partition 11. A cabinet door 2 is rotatably mounted on the front of the cabinet 1. An observation window 22 is embedded and fixedly connected inside the cabinet door 2, allowing operators to view the interior of the cabinet 1 through the observation window 22. A pivot 3 is fixedly connected to both the cabinet door 2 and the observation window 22 on the side closest to the interior of the cabinet 1. A handle 21 is fixedly connected to the side of the cabinet door 2 away from the interior of the cabinet body 1. The handle 21 is equipped with an anti-slip sleeve. Each shaft 3 has a support plate 31 rotatably mounted at one end. Each support plate 31 holds an LED test socket 34. The LED test socket 34 is a dedicated LED test socket, which has test holes that match the pins of the LED beads. It also integrates a power supply and current limiting circuit. When the LED beads are inserted into the test holes of the LED test socket 34, the LED beads are powered by the built-in battery of the LED test socket 34, and the LED beads automatically light up. Two parallel shafts are fixedly connected to the bottom of the cabinet body 1 and the top of the partition 11. The slide rails 32 are arranged, and the support plates 31 slide in cooperation with the corresponding two slide rails 32. Through the sliding connection between the support plates 31 and the slide rails 32, the rotational motion of the rotating shaft 3 can be converted into the linear motion of the support plates 31. A baffle 33 is fixedly connected to the front of each support plate 31. The front side of the LED test seat 34 is in contact with the rear side of the corresponding baffle 33. By setting the baffle 33, it is convenient for the operator to quickly place the LED test seat 34. Guide rods 4 are fixedly connected to the left and right sides of each support plate 31. A clamping plate 42 is slidably set on the outside of each guide rod 4. The clamping plate 42 slides in cooperation with the corresponding support plate 31. A spring 41 is sleeved on the outside of the guide rod 4. The two ends of the spring 41 are connected to the corresponding support plate 31 and the corresponding clamping plate 42 respectively, providing a reset force for the clamping plate 42. A protrusion 47 is fixedly connected to the top of each clamping plate 42. Two inclined blocks 45 are fixedly connected to the left and right inner walls of the cabinet 1. The protrusion 47 and the corresponding inclined block 45 are kept at the same height. The top of the cabinet 1 and the bottom of the partition 11 are connected to the detection camera 5 by bolts. The right side of the cabinet 1 is connected to the controller 6 by bolts. The detection camera 5 is electrically connected to the controller 6. The controller 6 is a programmable logic controller, model Huichuan Easy 521-24T4DT, with a built-in image acquisition and analysis module. It can receive the image information transmitted by the detection camera 5, perform real-time analysis of the light color distribution of the LED beads, and transmit the processing results to the display terminal.

[0022] like Figure 6As shown, it also includes a second guide rod 43, a second spring 44, and a buffer plate 46. Two symmetrically arranged guide rods 43 are slidably arranged on each clamping plate 42. A buffer plate 46 is fixedly connected between one end of two adjacent guide rods 43. A second spring 44 is sleeved on the outside of each guide rod 43. The two ends of the second spring 44 are respectively connected to the corresponding clamping plate 42 and the corresponding buffer plate 46, providing a reset force for the buffer plate 46.

[0023] When this device is needed, the operator first removes the LED test socket 34 from the support plate 31, inserts the LED beads one by one into the test holes of the LED test socket 34. After insertion, the LED beads automatically light up and enter the test state. Then, the LED test socket 34 is placed back on the support plate 31, so that the front side of the LED test socket 34 is in contact with the rear side of the baffle 33. Then, the cabinet door 2 is rotated counterclockwise to gradually close the cabinet 1 (viewed from the top of the cabinet 1 as the front). During the rotation of the cabinet door 2, the rotating shaft 3 is driven to rotate together. The rotating shaft 3 pushes the support plate 31 to slide backward along the slide rail 32. During the backward sliding of the support plate 31, the protrusion 47 gradually approaches and contacts the inclined block 45, and is squeezed by the inclined surface of the inclined block 45, which drives the clamping plate 42 to move inward, compressing the spring 41. The buffer plate 46 moves inward synchronously with the clamping plate 42, clamping the LED test socket 34. During the clamping process, the buffer plate 46 will first be squeezed by the LED test socket 34 and move outward. The cabinet door 2 rotates to fully close the cabinet 1, and the support plate 31 moves the LED test base 34 to the bottom of the detection camera 5. At this time, the detection camera 5 is activated by the controller 6 to capture the color distribution of the LED beads on the LED test base 34. The controller 6 processes and analyzes the received image information in real time to determine whether the color of each LED bead meets the preset standard, and transmits the final detection result to the display terminal for the operator to view and record. After the detection is completed, the detection camera 5 is turned off, the cabinet door 2 is rotated clockwise to open the cabinet 1, the pivot 3 pulls the support plate 31 to slide forward along the slide rail 32, so that the protrusion 47 disengages from the inclined block 45, the spring 41 and the spring 44 return to their original state, and push the clamping plate 42 and the buffer plate 46 to move outward to release the LED test base 34. At this time, the LED test base 34 can be removed and the LED beads can be removed.
