[0026] To facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below in conjunction with specific embodiments.

[0027] The iron ring in the technical solution of the present invention refers to the process of adhering the LED core to the blue film and then adhering the blue film to the iron ring during the LED core test. The iron ring supports the LED core to facilitate angle adjustment, transfer and testing of the LED core. Of course, the technical solution protected by this patent is not limited to iron rings for LED cores.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, an iron ring angle adjustment mechanism 100, the iron ring 101 carries LED chips, and it is necessary to ensure that the direction of the LED chips is consistent with the preset direction to facilitate the position identification of the LED chips and the accurate setting of the test motion trajectory; the iron ring transfer mechanism 100 includes,

[0029] An angle adjustment mechanism 20 is provided for the carrying plane 21, which can adjust the angle of the iron ring 101 placed on the carrying plane 21 by rotating; the angle adjustment mechanism 20 also includes a lifting assembly 22 connected to the carrying plane 21, which is used to adjust the height of the carrying plane 21, and ultimately adjust the height of the iron ring 101 placed on the carrying plane 21;

[0030] The support parts 30 provided with adjusting push rods 31 are distributed on both sides of the angle adjustment mechanism 20 in the horizontal direction, that is, there are two / two groups of support parts 30, and the support parts 30 are provided at both ends of the iron ring 101 to achieve support for the iron ring 101; and the distance between the support parts 30 is less than the diameter of the iron ring 101, and the function of the iron ring 101 is to support; the adjusting push rods 31 extend in the vertical direction and are respectively connected to the linear drive parts 32, and the "respectively" here means that the two / two groups of support parts 30 each have at least one linear drive part 32, and is not used to limit the multiple adjusting push rods 31 on the same support part 30 to be controlled by one / multiple linear drive parts 32; so that the adjusting push rod 31 can move in the horizontal direction; when the iron ring 101 is placed on the support part 30, the linear drive part 32 causes the adjusting push rod 31 to move and stop at the edge of the iron ring 101, so that the center of the iron ring 101 The center coincides with the rotation center of the bearing plane 21; that is, by adjusting the top rod 31 along the edge of the iron ring 101, the geometric center of the iron ring 101 is synchronously stopped at the iron ring 101, so that the geometric center of the iron ring 101 is coincident with the rotation center of the bearing plane 21 (taking the bearing plane 21 as a circle as an example, its geometric center is the center of the circle). The geometric center here is the center of the circle, the center of the circumscribed circle of a regular polygon, etc., which is convenient for determining the reference position of the bearing plane 21. The adjustment of the iron ring 101 by the adjusting top rod 31 can be aligned with the reference position; then the angle adjustment mechanism 20 rises, so that the iron ring 101 is supported on the bearing plane 21 (the blue film on the iron ring 101 is directly fitted with the bearing plane 21 to support the iron ring 101), and then the bearing plane 21 rotates to achieve angle adjustment of the LED core particles on the iron ring 101; at this time, it is meaningful to adjust the angle of the iron ring 101 to achieve angle adjustment of the LED core particles.

[0031] By adopting the above technical solution, the iron ring 101 is placed on the support part 30, and the geometric center of the iron ring 101 is made to coincide with the rotation center of the supporting plane 21 by adjusting the top rod 31. Then the supporting plane 21 supports the iron ring 101 and rotates, thereby realizing the angle adjustment of the LED core particle on the iron ring 101.

[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, the supporting plane 21 is a plane provided with adsorption holes, which facilitates the adsorption of the blue film on the supporting plane 21, so that the position adjustment of the iron ring 101 is the same as the state of the LED core particle test, thereby facilitating the precise adjustment of the position and direction of the iron ring 101.

[0033] like Figure 1 、 Figure 2 and Figure 3 As shown, the support portion 30 is provided with a limiting opening 32, and the positioning push rod 31 is partially accommodated in the limiting opening 32 and slides along the limiting opening 32 under the action of the linear drive portion 32, that is, the limiting opening 32 is used to limit the movement direction of the positioning push rod 31, so that the positioning push rod 31 acts on the iron ring 101 in the direction limited by the limiting opening 32, and finally makes the geometric center of the iron ring 101 coincide with the rotation center of the bearing plane 21; so that the movement position of the positioning push rod 31 is stable and reliable.

[0034] like Figure 1 、 Figure 2 and Figure 3 As shown, there are multiple positioning push rods 31, and they are connected to the linear drive part 32 through the mounting plate 33; the multiple positioning push rods 31 are distributed in an arc shape along the rotation center of the load-bearing plane 21; thereby, the iron ring 101 can coincide with the rotation center of the load-bearing plane 21, and the structure is stable and reliable; the linear drive part 32 is a linear cylinder, which is a specific solution for realizing linear motion and is not used to limit linear cylinders. Technical solutions for driving linear motion such as linear motors and rotary motors driving linear motion should belong to technical solutions equivalent to linear cylinders.

[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an iron ring transfer device 200 is used to transfer the iron ring 101 from other positions to the angle adjustment mechanism 100 to achieve angle adjustment of the iron ring 101; the iron ring transfer device 200 is provided with the above-mentioned iron ring angle adjustment mechanism 100,

[0036] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the iron ring transfer device 200 also includes a material moving component 40, and the material moving component 40 includes a clamping device 41 and a linear guide 42. The clamping device 41 is connected to the linear guide 42 and can reach the support portion 30, so that the clamping device 41 can transfer the iron ring 101 to the support portion 30; the clamping device 41 includes a first clamping portion 411, and a second clamping portion 412 that can move relative to the first clamping portion 411, and the second clamping portion 412 is moved by a cylinder or other linear motion. Control components to clamp the iron ring 101 between the first clamping part 411 and the second clamping part 412, thereby fixing the iron ring 101 during the transfer process; the clamping device 41 also includes a lifting cylinder 413, and the first clamping part 411 and the second clamping part 412 are both connected to the lifting cylinder 413, thereby adjusting the height direction of the first clamping part 411 and the second clamping part 412, thereby meeting the different position controls of the height of the clamped iron ring 101 and the height of the transferred iron ring 101.

[0037] By adopting the above technical solution, the material moving assembly 40 can meet the requirements of adjusting the height of the iron ring 101 to be clamped, transferred, and placed on the support portion 30 at different heights.

[0038] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the support part 30 is parallel to the linear guide rail 42; that is, the starting position and placement position of the transfer of the iron ring 101 are both located on the support part 30, and only belong to different positions on the support part 30, and the transfer of the iron ring 101 is stable and reliable; the support part 30 is provided with an iron ring pre-setting part 34 for placing the iron ring transferred to the angle adjustment mechanism 20, and the iron ring pre-setting part 34 is away from the angle adjustment mechanism 20, making full use of the space of the support part 30, thereby reducing the occupied space.

[0039] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the iron ring pre-setting portion 34 is provided with a limiting portion 341, and the limiting portion 341 is used to place the iron ring 101 so that the clamping device 41 can transfer the iron ring 101; the limiting portion 341 is used to adjust the relative position of the iron ring 101, thereby realizing the position adjustment of the iron ring 101 before the transfer; of course, the limiting portion 341 can realize the position adjustment of the iron ring 101 by setting the same structure as the support portion 30, thereby facilitating the clamping device 41 to accurately clamp the iron ring 101.

[0040] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the iron ring transfer device 200 further includes an iron ring turning portion 50, and the iron ring turning portion 50 includes:

[0041] A rotary drive unit 51, wherein the axis of the output shaft of the rotary drive unit 51 is horizontally arranged;

[0042] The iron ring fixing part 52 is pivotally connected to the output shaft of the rotation driving part 51, so that the iron ring fixing part 52 can be flipped under the control of the rotation driving part 51, and the iron ring 101 is flipped to the iron ring pre-setting part 34; the iron ring fixing part 52 includes a two-way cylinder 521, and a clamping block 522 connected to the two-way cylinder 521, and the two-way cylinder 521 drives the two clamping blocks 522 to be relatively close to or away from each other, thereby fixing the iron ring 101; in the technical solution of the present invention, since it can only be fixed from both sides of the iron ring 101, it can only be achieved by moving the two clamping blocks 522 away from each other so that the distance between the two clamping blocks 522 is greater than the diameter of the iron ring 101. When the iron ring 101 is located between the two clamping blocks 522, the two clamping blocks 522 are brought close to each other, thereby clamping the iron ring 101.

[0043] By adopting the above technical solution, the iron ring 101 can be flipped from a non-horizontal placement to a horizontal placement, and then the iron ring 101 is transferred to the support part 30 by the clamping device 41 to complete the adjustment of the angle of the iron ring 101.

[0044] The above are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. It should be recognized that non-inventive modifications and changes made by those skilled in the art after understanding the technical solution of the present invention should also fall within the scope of protection and disclosure of the present invention.
