Description

Technical Field

[0001] The invention relates to the technical field of PCB board splitter components, in particular to a circulating conveying mechanism for RGB lamp calibration. Background Art

[0002] The RGB lamp is composed of three LEDs corresponding to the three colors of red, green and blue. The PWM control signal ratios of various target colors are calculated through calibration. In the automotive industry, the calibration of RGB atmosphere lights is very demanding. After calibration, the color coordinate xy deviation of the target color is generally required to be within ±0.01, and the luminous flux deviation is required to be within ±20%. Therefore, in fields such as the automotive industry, RGB lamp calibration is also one of the important and cumbersome process nodes. Existing RGB lamp calibration often adopts an assembly line method, and the RGB lamp is calibrated in turn by manual or manual handheld corresponding detection tools, and the calibration efficiency is very low. An important reason for the low calibration efficiency is that the jig carrying the RGB lamp to be calibrated is delivered to the corresponding calibration position by manual or simple mechanical means, and it is impossible to achieve very efficient automatic delivery to the calibration position, which leads to a long calibration time and low calibration efficiency.

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0035] like Figures 1 to 8 As shown, a circulating conveying mechanism for RGB lamp calibration includes a base plate 10, and a left cylinder 1, a first station 2, a first cylinder 3, a second station 4, a second cylinder 5, a third station 6, a third cylinder 7, a fourth station 8, a right cylinder 9, a base plate 10, a right slide rail 11, a right slide bar 12, a first transverse slide rail 13, a fourth cylinder 14, a first movable plate 15, a fifth cylinder 16, a left slide bar 17, a left slide rail 18, a first calibration mechanism 19, a second calibration mechanism 20, a first transverse cylinder 21, a first transverse slide bar 22, and a second transverse slide bar 23. 3 and the second transverse cylinder 24, the first cylinder 3, the second cylinder 5, the third cylinder 7, the first transverse cylinder 21, the first transverse slide bar 22, the second transverse slide bar 23 and the second transverse cylinder 24 are installed at the same end of the base plate 10, and the left cylinder 1, the first station 2, the second station 4, the third station 6, the fourth station 8, the right cylinder 9, the right slide rail 11, the right slide bar 12, the first transverse slide rail 13, the fourth cylinder 14, the first movable plate 15, the fifth cylinder 16, the left slide bar 17, the left slide rail 18, the first calibration mechanism 19 and the second calibration mechanism 20 are installed at the other end of the base plate 10.

[0036] The right cylinder 9 is slidably mounted on the right slide bar 12 and can slide along the right slide bar 12 or be fixedly mounted on the right slide bar 12. The output shaft of the right cylinder 9 is connected to the fourth station 8 to drive the fourth station 8 to move. The fourth station 8 is fixedly mounted on the right track plate (not shown in the figure), and the right track plate is slidably mounted on the right slide rail 11, so that the right cylinder 9 can drive the fourth station 8 to slide along the right slide rail 11, and at least reach the corresponding different positions. The left cylinder 1 is slidably mounted on the left slide bar 17 and can slide along the left slide bar 17 or be fixedly mounted on the left slide bar 17. The output shaft of the left cylinder 1 is connected to the first station 2 to drive the first station 2 to move. The first station 2 is fixedly mounted on the left track plate (not shown in the figure), and the left track plate is slidably mounted on the left slide rail 18, so that the left cylinder 1 can drive the first station 2 to slide along the left slide rail 18, and at least reach the third position and the fourth position.

[0037] The output shaft of the first cylinder 3 is movably connected to the second station 4, and the output shaft of the second cylinder 5 is movably connected to the fourth station 8. The so-called movably connected means that the output shaft of the cylinder can be connected to the corresponding station, and the output shaft of the cylinder can also be separated from the station.

[0038] The second station 4 and the fourth station 8 are both slidably mounted on the second transverse rail (not shown in the figure), and can slide along the second transverse rail, that is, to achieve horizontal left and right sliding. The second transverse rail is between the left rail 18 and the right rail 11, and is located at one end of the left rail 18 and the right rail 11. The left rail 18 and the right rail 11 are arranged in parallel with each other. The second transverse rail is arranged in parallel with the first transverse rail 13. The first transverse rail 13 is also between the left rail 18 and the right rail 11, and is located at the other end of the left rail 18 and the right rail 11. The second transverse rail and the first transverse rail 13 are both perpendicular to the left rail 18 and the right rail 11.

[0039] The first cylinder 3, the second cylinder 5 and the fourth cylinder 14 are all fixedly mounted on the second movable plate. The three cylinders are arranged in parallel with each other. The second movable plate is connected to the output shaft of the first transverse cylinder 21 through the first slide plate. The first slide plate is slidably mounted on the first transverse slide bar 22, so that the first slide plate can slide along the first transverse slide bar 22, so that the first transverse cylinder 21 can drive the first cylinder 3, the second cylinder 5 and the fourth cylinder 14 to move left and right synchronously through the second movable plate.

[0040] The fourth cylinder 14 and the fifth cylinder 16 are both fixedly mounted on the first movable plate 15, and the two cylinders are respectively fixed at both ends of the first movable plate 15. The first movable plate 15 is connected to the output shaft of the second transverse cylinder 24 through the second slide plate, and the second slide plate is slidably mounted on the second transverse slide bar 23, so that the second slide plate can slide along the second transverse slide bar 23, so that the second transverse cylinder 24 can drive the fourth cylinder 14 and the fifth cylinder 16 to move left and right synchronously through the first movable plate 15.

[0041] The first calibration mechanism 19 and the second calibration mechanism 20 are fixedly installed on the bottom plate 10 in parallel with each other, the first calibration mechanism 19 is located in front of the second station 4, and the second calibration mechanism 20 is located in front of the third station 6. The first calibration mechanism 19 is used to calibrate the RGB lamp to be calibrated on the second station 4, and the second calibration mechanism 20 is used to calibrate the RGB lamp to be calibrated on the third station 6. The RGB lamp calibration method is a prior art and is not the protection and improvement point of this application, so it will not be repeated here.

[0042] The first station 2 to the fourth station 8 have the same structure, and these four stations are used to receive and transport jigs carrying RGB lamps to be calibrated, so that the RGB lamps to be calibrated can be continuously sent to the second station 4 and the third station 6 for calibration, and sent out of the second station 4 and the third station 6 after the calibration is completed.

[0043] Taking the first workstation 2 as an example, its structure is described. The workstation includes a vertical plate 25, a front transverse plate 27, a connecting block 28, a slide rail seat 31, and a rear transverse plate 33. The front transverse plate 27 is fixedly connected to one end of the bottom of the vertical plate 25, and the rear transverse plate 33 is fixedly connected to the other end of the bottom of the vertical plate 25. The front transverse plate 27, the vertical plate 25, and the rear transverse plate 33 can be an integral structure or can be assembled and connected together as separate components. A first notch 26 opening outward is dug on the front transverse plate 27, and a second notch 34 opening outward is also dug on the rear transverse plate 33. The first notch 26 and the second notch 34 are used for output connection with the corresponding cylinder after the workstation reaches the corresponding position. A slide rail seat 31 is fixedly installed at the bottom of the front transverse plate 27. The slide rail seat 31 and the front transverse plate 27 are located on the same side of the vertical plate 25, and the slide rail seat 31 is arranged along the transverse direction of the vertical plate 25. A transverse slide rail groove 30 is dug on the slide rail seat 31. The transverse slide rail groove 30 is arranged axially along the slide rail seat 31 and opens downward, that is, the opening is in the direction away from the front transverse plate 27. The side of the front transverse plate 27 away from the vertical plate 25 is fixedly connected to the connecting block 28. A cam 32 is fixedly installed at the lower end of the connecting block 28. The cam 32 abuts against the arc groove on the base 29. The base 29 prevents the workstation from moving at will by abutting against the cam 32. The base 29 is fixedly installed on the bottom plate 10 or other positions and is located directly below the corresponding workstation.

[0044] In actual use, in the initial state, the first to fourth workstations 2 to 8 are all located at the uppermost end of the bottom plate 10 and are arranged flush, that is, the four workstations are located on the same straight line in the horizontal direction. Figure 1 The four stations at the upper middle end are in the initial state. Among them, the output shaft of the first cylinder 3 is connected to the second notch 34 on the second station 4, that is, the output shaft passes through the second notch 34 and locks the second cylinder 5 on the second transverse slide rail. Similarly, the second cylinder 5 also locks the third station 6 on the second transverse slide rail. In this state, the second station 4 and the third station 6 cannot slide left and right on the second transverse slide rail. The cam 32 on the first station 2 abuts against the arc groove on the base 29 to prevent the first station 2 from moving left and right at will, that is, to limit it. Of course, under the action of external force, due to its arc shape, it can slide out of the arc groove. Similarly, the cam 32 on the fourth station 8 abuts against the arc groove on the base 29 to prevent the fourth station 8 from moving left and right, that is, to limit it.

[0045] When the outside (such as the production line) sends the jig carrying the RGB lamp to be calibrated to the first station 2, a detection or sensing device can be used to detect whether there is a jig of the RGB lamp to be calibrated on the first station 2. After detecting that there is a jig of the RGB lamp to be calibrated on the first station 2, the left cylinder 1 drives the first station 2 to slide along the left slide rail 18 to the lowest end. Synchronously, the second transverse cylinder 24 drives the first movable plate to move to the left and drives the fourth cylinder 14 and the fifth cylinder 16 to move to the left together, so that the output shaft of the fourth cylinder 14 is opposite to the first station 2 on the first station 2, so that the output shaft of the fourth cylinder 14 extends forward and is just connected to the first recess 26, so that the fourth cylinder 14 is connected to the first station 2, and the fourth cylinder 14 is located in the middle of the first transverse slide rail 13. Synchronously, the right cylinder 9 drives the fourth station 8 to the lowest end, and the fourth station 8 is flush with the first station 2, that is, it is in the same straight line in the horizontal direction.

[0046] Next, the output shaft of the fifth cylinder 16 extends out and connects with the first notch 26 on the first station 2, and the second transverse cylinder 24 drives the fifth cylinder 16 and the fourth cylinder 14 to move right to the middle position. At this time, the fifth cylinder 16 sends the first station 2 to the base 29 located in the middle of the first transverse slide rail 13, that is, the cam 32 on the first station 2 is just stuck in the arc-shaped groove on the base 29, and the base 29 is just located on one side of the first transverse slide rail 13 and in the middle of the first transverse slide rail 13. The output shaft of the fourth cylinder 14 can just extend into the first notch 26 on the first station 2, and then the left cylinder 1 drives the bottom frame (not shown in the figure) that originally carried the first station 2 back to the initial position, and the fourth cylinder 14 sends the first station 2 along the first transverse slide rail 1 3 moves to the leftmost side and feeds the bottom frame brought down by the right cylinder 9, then the right cylinder 9 carries the first station 2 to the top and aligns it with the second transverse rail, so that the transverse rail groove 30 on the first station 2 can align with the second transverse rail, and after the third cylinder 7 is connected to the second notch 34 on the first station 2, it moves to the left under the action of the first transverse cylinder 21, so that the first station 2 moves to the original position of the third station 6, that is, the first station 2 is facing the second calibration mechanism 20, and after continuing to move, the first station 2 moves to the first calibration mechanism 19, and the first calibration mechanism 19 and / or the second calibration mechanism 20 calibrate the RGB lamp to be calibrated on the first station 2 which is originally the position of the second station 4 and the position of the third station 6. When moving in sequence, the four stations move in a counterclockwise cycle, so that the RGB lamp to be calibrated can be calibrated continuously and continuously, and the four stations reach the corresponding positions to achieve connection, so as to prevent the RGB lamp to be calibrated on the station from falling off. Among them, the RGB lamp after calibration can be taken out after being moved to the original position of the first station 2, for example, by hand or an external robot, and the new RGB lamp to be calibrated is sent to the original position of the first station 2 again for the next round of RGB lamp calibration.

[0047] Among them, the first station 2 to the fourth station 8 are each connected to a bottom frame, and the bottom frame is slidably installed on the corresponding slide rail, that is, the first station 2 is slidably installed on the left slide rail 18 through the bottom frame, the fourth station 8 is slidably installed on the right slide rail 11 through the bottom frame, the second station 4 and the third station 6 are slidably installed on the second transverse slide rail through their respective bottom frames, and the bottom frames are always on their respective slide rails. After each station is connected by the corresponding cylinder, it can be moved from one slide rail to another, so that the station carrying the RGB lamp to be calibrated is moved to different slide rails, thereby realizing transportation to the corresponding position, and calibrated by aligning one or both of the two calibration mechanisms.

[0048] The present invention can effectively, quickly and smoothly transport the RGB lamp to be calibrated to the corresponding position, so that the calibration mechanism can well calibrate the RGB lamp to be calibrated, saving the processing time of the calibration link in the production and assembly process of RGB, etc., and improving the production efficiency.

[0049] The embodiment disclosed in this specification is only an example of a unilateral feature of the present invention, and the protection scope of the present invention is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of the present invention. For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
