[0030] The implementation of this utility model will be described in detail below with reference to specific embodiments.
[0031] In this embodiment:
[0032] Reference Figures 1-4 The diagram shows a preferred embodiment of the present invention.
[0033] The LED bead testing device of this embodiment includes a housing 1, a display screen 2 on one side of the housing 1, a tray 3 inside the housing 1, and a limiting adjustment device 4 on one side of the tray 3. The limiting adjustment device 4 uses a first limiting plate 47 and a second limiting plate 48 to limit and separate the LED beads inside the tray 3. The effect achieved by the above components is as follows: when inspecting the appearance of the LED beads, the beads are placed on the surface of the tray 3. At this time, the limiting adjustment device 4 limits and separates the LED beads inside the tray 3, moving the tray 3 into the housing 1 of the device. Then, the lamp inside the housing 1 illuminates the light, and the camera inside the housing 1 performs appearance inspection on the surface of the LED beads. Finally, the inspection result is output through the display screen 2 on the surface of the housing 1.
[0034] Figures 1-4The limit adjustment device 4 shown includes a mounting plate 41, which is fixedly connected to the tray 3. A motor 42 is fixedly connected to one side of the mounting plate 41. A threaded rod 43 is fixedly connected to the output end of the motor 42. The threaded rod 43 is rotatably connected to the mounting plate 41. A sliding block 44 is threadedly connected to one side of the threaded rod 43. The sliding block 44 is slidably connected to the mounting plate 41. An electric telescopic rod 45 is fixedly connected to one side of the sliding block 44. A placement plate 46 is fixedly connected to the output end of the electric telescopic rod 45. A plurality of first limit plates 47 are fixedly connected to one side of the placement plate 46. A second limit plate 48 is slidably connected to one side of the plurality of first limit plates 47. The effect achieved by the above components is as follows: When the LED beads are placed inside the tray 3, the second limiting plate 48 can be moved to change the size of the separation area formed between the first limiting plate 47 and the second limiting plate 48, allowing LED beads of different sizes to be placed inside the tray 3 for separation and limitation. After the LED beads are placed inside the tray 3 and separated by the first limiting plate 47 and the second limiting plate 48, the tray 3 is moved to the designated position, and the electric telescopic rod 45 is activated, causing the placement plate 46 to move the first limiting plate 47 and the second limiting plate 48 away from the tray 3. The motor 42 on one side of the mounting plate 41 is activated, causing the motor 42 to drive the threaded rod 43 to rotate. The threaded rod 43, through the sliding block 44, drives the placement plate 46 at the output end of the electric telescopic rod 45 to move. The movement of the first limiting plate 47 and the second limiting plate 48 away from the tray 3 can be achieved by using the mounting plate 41 and the threaded rod 43 of different lengths to change the maximum distance between the first limiting plate 47 and the second limiting plate 48 and the tray 3. By using the limiting adjustment device 4, the LED beads inside the tray 3 can be limited and separated, preventing multiple LED beads inside the tray 3 from being easily moved by force when the tray 3 moves, which could cause some areas of some LED beads to come into contact with each other. Furthermore, when inspecting the LED beads, the first limiting plate 47 and the second limiting plate 48 can be disengaged from the LED beads inside the tray 3, so that the appearance inspection of the LED beads is not affected, thereby improving the effectiveness of the inspection device.
[0035] Figures 1-4 A control frame 49 is fixedly connected to one side of the second limiting plate 48 shown, and a rubber sleeve 410 is fixedly connected to one side of the control frame 49. The effect achieved by the above components is to increase the contact area between the second limiting plate 48 and the operator by using the control frame 49 with the rubber sleeve 410, making the second limiting plate 48 easier to move.
[0036] Figures 1-4A fixing component 5 is provided on one side of the second limiting plate 48 shown. The effect achieved by the above component is that the adjusted position of the second limiting plate 48 can be fixed by using the fixing component 5, thereby improving the usability of the second limiting plate 48. The fixing component 5 includes a U-shaped frame 51, which is fixedly connected to the second limiting plate 48. A first bolt 52 is threaded into the U-shaped frame 51, and a through hole 53 is opened on the side of the second limiting plate 48 near the first bolt 52. The effect achieved by the above component is that after the second limiting plate 48 is adjusted to the position of the first limiting plate 47, the first bolt 52 can be rotated, causing the first bolt 52 to rotate inside the U-shaped frame 51 and pass through the through hole 53 of the second limiting plate 48, so that the first bolt 52 abuts and fixes against the first limiting plate 47, thus completing the fixation of the position of the second limiting plate 48. By using the fixing component 5, the adjusted position of the second limiting plate 48 on the first limiting plate 47 can be fixed, thereby improving the usability of the second limiting plate 48. Several anti-slip blocks 54 are fixedly connected to one side of the first bolt 52, and the anti-slip blocks 54 are arranged at equal intervals on one side of the first bolt 52. The effect achieved by the above components is to increase the friction between the first bolt 52 and the operator by using the anti-slip blocks 54, making the first bolt 52 easier to rotate.
[0037] Figures 1-4 The mounting plate 41 shown has a protective component 6 on the side near the motor 42. The protective component 6 includes a second bolt 61, which is threaded to the mounting plate 41. A protective cover 62 is threaded to one side of the second bolt 61. The size of the protective cover 62 is adapted to the size of the motor 42. Several heat dissipation holes 63 are opened on the surface of the protective cover 62. A washer 64 abuts against one side of the second bolt 61. The effect achieved by the above components is that when the motor 42 is in use, the protective cover 62 with heat dissipation holes 63 can cover the motor 42. By rotating the second bolt 61, the second bolt 61 passes through the washer 64 and the protective cover 62 and is fixed to the mounting plate 41, thus fixing the protective cover 62 to the surface of the motor 42. By using the protective component 6, the motor 42 can be shielded and protected, avoiding damage to the motor 42 and affecting its use, thereby improving the performance of the limit adjustment device 4.
[0038] Working Principle: During the appearance inspection of LED beads, the beads are placed on the surface of tray 3. While placing the LED beads inside tray 3, the operator can hold the second limiting plate 48 and move it (the second limiting plate 48 slides on the surface of the first limiting plate 47), changing the size of the separation area formed between the first limiting plate 47 and the second limiting plate 48. This allows LED beads of different sizes to be placed inside tray 3 for separation and limitation. At this time, the operator rotates the first bolt 52, causing it to rotate inside the U-shaped frame 51 and pass through the through hole 53 of the second limiting plate 48, thus abutting and fixing the first limiting plate 47. This completes the fixation of the second limiting plate 48. After the LED beads are placed inside tray 3 and separated by the first limiting plate 47 and the second limiting plate 48, tray 3 is moved to the designated position, and the electric telescopic rod 45 is activated to allow the placement of the LED beads to proceed. Plate 46 drives the first limiting plate 47 and the second limiting plate 48 to detach from the tray 3. (Place plate 46, the first limiting plate 47 and the second limiting plate 48 are a whole and can be moved upward by the electric telescopic rod 45.) Start the motor 42 on one side of the mounting plate 41, so that the motor 42 drives the threaded rod 43 to rotate. The threaded rod 43 drives the placement plate 46 at the output end of the electric telescopic rod 45 to move through the sliding block 44, so that the placement plate 46 is away from the tray 3. Since the placement plate 46, the first limiting plate 47 and the second limiting plate 48 are a whole, after the placement plate 46 moves, it will carry the first limiting plate 47 and the second limiting plate 48 away from the tray 3. Finally, the placement plate 46 is at the upper edge of the tray 3, and the first limiting plate 47 and the second limiting plate 48 are completely detached from the tray 3. The lamp inside the outer shell 1 emits light, and the camera inside the outer shell 1 performs appearance inspection on the surface of the LED beads. Finally, the inspection result is output through the display screen 2 on the surface of the outer shell 1.
[0039] When using motor 42, the protective cover 62 with heat dissipation holes 63 can be used to cover motor 42. The second bolt 61 is rotated so that the second bolt 61 passes through the washer 64 and the protective cover 62 and is fixed to the mounting plate 41, so that the protective cover 62 is fixed to the surface of motor 42 and the motor 42 is shielded and protected.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
