Description

Technical Field

[0001] This invention relates to the field of digital tube splicing, specifically a side-emitting LED digital tube splicing device. Background Technology

[0002] Side-emitting LED digital tubes are widely used in electronic displays, instruments, intelligent control and other fields due to their advantages such as uniform light emission, small size and convenient installation. In the production process, the splicing accuracy and efficiency of the PCB substrate and the side-emitting LED digital tube directly determine the product quality and production capacity. Therefore, splicing equipment is one of the key equipment in the large-scale production of side-emitting LED digital tubes.

[0003] Currently, existing splicing equipment for side-emitting LED digital tubes and PCB substrates has many shortcomings, making it difficult to meet the demands of large-scale, high-precision production. Regarding splicing accuracy, most existing equipment lacks flexible and precise adjustment mechanisms, failing to achieve accurate alignment between the PCB substrate and the side-emitting LED digital tube at any position. Because the pin arrangement of the side-emitting LED digital tube is precise and the PCB substrate pad positions are strictly required, any deviation in alignment can easily lead to misalignment between the pins and pads. This not only affects the electrical connection stability after splicing but may also damage the device, increasing production costs and rework rates. This fails to meet the production requirements for precise splicing, contradicting the core requirement of accurate pin-pad alignment and avoiding misalignment damage in side-emitting LED digital tube splicing.

[0004] Regarding splicing efficiency, existing splicing equipment suffers from cumbersome PCB substrate switching methods, often relying on manual labor or a single fixed structure for substrate replacement. This switching process is time-consuming and cannot achieve rapid PCB substrate switching. Simultaneously, most equipment lacks precise feeding control capabilities in its feeding components, leading to potential deviations in the feeding position of side-emitting LED digital tubes. Frequent manual adjustments are required, further slowing down the splicing progress. Furthermore, some equipment has complex structures, numerous parts, and cumbersome operating procedures, requiring specialized operators for debugging and operation. This not only increases labor costs but also makes it susceptible to operational errors that could affect splicing quality and efficiency, hindering the development of high-efficiency production.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0027] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Please refer to the attached drawings. A side-emitting LED digital tube splicing device includes a device platform 1 and a column 2 fixed to the rear top of the device platform 1. The column 2 serves as a support carrier for the crossbeam 3. The top of the column 2 is fixedly connected to the crossbeam 3 to form the upper support frame of the device.

[0031] To achieve the lateral position adjustment of the digital tube, a sliding base 4 is slidably connected to the crossbeam 3. The lateral movement of the sliding base 4 is driven and controlled by a linear motor 5 fixedly installed on the rear side of the crossbeam 3. When the linear motor 5 is working, it can drive the sliding base 4 to slide smoothly along the crossbeam 3, thereby adjusting the lateral working position (X direction adjustment) of the subsequent gripping component.

[0032] Considering the need to adapt to PCB substrates and digital tube installation requirements of different heights during the splicing process, a height adjustment component 6 is installed on the sliding base 4, and the robotic arm 7 used to hold the side-emitting LED digital tube is installed on the height adjustment component 6. By the movement of the height adjustment component 6, the vertical height of the robotic arm 7 can be flexibly adjusted to ensure that the digital tube can be accurately aligned with the installation position of the PCB substrate.

[0033] Specifically, the height adjustment component 6 consists of a first motor 11 fixedly connected to the sliding base 4. A first belt 12 arranged in the height direction is sleeved on the output shaft of the first motor 11. One point of the first belt 12 is fixedly connected to the longitudinal base plate 13. The robot arm 7 is connected to the longitudinal base plate 13. When the first motor 11 is started, it will drive the first belt 12 to rotate, thereby driving the longitudinal base plate 13 to rise and fall in the vertical direction, realizing the height adjustment (Z direction adjustment) of the robot arm 7.

[0034] To improve the lifting stability of the longitudinal base plate 13, the longitudinal base plate 13 and the sliding base 4 are connected by a sliding connection. At the same time, to further optimize the installation position adjustment flexibility of the robot arm 7, a longitudinal slide groove 14 is fixedly connected to the longitudinal base plate 13, and an L-shaped connecting seat 15 is slidably connected to the longitudinal slide groove 14. The robot arm 7 is fixed on the L-shaped connecting seat 15, and the L-shaped connecting seat 15 and the longitudinal slide groove 14 are locked together by bolts. Loosening the bolts can adjust the position of the L-shaped connecting seat 15 on the longitudinal slide groove 14, thereby fine-tuning the longitudinal posture of the robot arm 7.

[0035] In conjunction with the upper gripping mechanism, the equipment platform 1 is equipped with a longitudinal drive component 8 for driving the PCB substrate to move longitudinally. The longitudinal drive component 8 is equipped with a sliding base 9, and the sliding base 9 is equipped with a positioning component 10 for positioning the PCB substrate. During operation, the longitudinal drive component 8 drives the sliding base 9 and the positioning component 10 to move longitudinally. In conjunction with the lateral and longitudinal movements of the robot arm 7, the robot arm 7 can ultimately accurately splice the digital tubes it holds onto the PCB substrate.

[0036] The specific structure of the longitudinal drive component 8 is as follows: it includes a second motor 16 fixed inside the equipment platform 1, a second belt 17 longitudinally distributed on the output shaft of the second motor 16, a sliding base 9 fixedly connected to a point on the second belt 17, and the sliding base 9 and the equipment platform 1 are slidably connected. When the second motor 16 is started, the second belt 17 rotates and drives the sliding base 9 to slide smoothly along the longitudinal direction of the equipment platform 1, providing power for the longitudinal position adjustment of the PCB substrate (Y direction adjustment).

[0037] The positioning component 10 is used to achieve precise positioning and angle adjustment of the PCB substrate. It includes a positioning shaft 18 that is rotatably connected to the sliding base 9. A rotating plate 19 is fixedly connected to the top of the positioning shaft 18. The rotating plate 19 has slots 20 on both sides. The slots 20 are used to clamp the positioning box 21. When the positioning box 21 is placed on the rotating plate 19, the positioning box 21 can be quickly clamped and fixed through the slots 20 to prevent the positioning box 21 from shifting during the splicing process.

[0038] To achieve the angular positioning of the rotating plate 19, symmetrical positioning grooves are provided on both sides of the positioning shaft 18. An elastic telescopic rod 22 is fixedly connected to the sliding base 9, and a roller 23 is fixedly connected to the end of the elastic telescopic rod 22. Under the elastic force of the elastic telescopic rod 22, the roller 23 always abuts against the surface of the positioning shaft 18. When the positioning shaft 18 is rotated to adjust the angle of the rotating plate 19 to a suitable position, the roller 23 will cooperate with the positioning groove on the positioning shaft 18 and engage in the positioning groove to lock the angle of the rotating plate 19 and ensure the stability of the positioning angle of the PCB substrate.

[0039] The positioning box 21, as the direct support and clamping component for the PCB substrate, adopts a hollow box structure. A first screw 24 is rotatably connected to its inner side. The outer side of the first screw 24 is provided with symmetrically distributed threads, and two clamping plates 25 are threadedly connected to the outer side of the first screw 24. The clamping plates 25 pass through the positioning box 21 and are slidably connected to the top side wall of the positioning box 21. When the first screw 24 is rotated, the two clamping plates 25 will move closer or further apart under the action of the symmetrical threads, thereby clamping and releasing the PCB substrate placed in the positioning box 21, ensuring the stability of the PCB substrate position during the splicing process.

[0040] Two positioning boxes 21 are connected to the front and rear sides of the top of the turntable 19. When the PCB substrate above one of the positioning boxes 21 is being spliced, the positioning box 21 on the other side can be removed to facilitate the removal of the spliced ​​PCB substrate above it. The positioning box 21 and the PCB substrate are then placed so that the unspliced ​​PCB substrate can be quickly switched to the splicing position after the splicing operation on the other side is completed.

[0041] To achieve automatic supply of digital tubes and avoid the impact of manual feeding on splicing efficiency, the equipment is also equipped with a feeding component 26. The feeding component 26 includes a support rod 27 that is slidably connected to the equipment platform 1. A feeding platform 28 is set on the top of the support rod 27. A conveying unit 29 for supplying side-emitting LED digital tubes is installed on the top of the feeding platform 28. The digital tubes are conveyed to the designated picking position through the conveying unit 29, making it easy for the robot arm 7 to grab them.

[0042] The lateral position adjustment of the feeding assembly 26 is achieved by the following structure: a third motor 30 is fixedly connected to the side of the equipment platform 1, and a second screw 31 is fixedly connected to the output shaft of the third motor 30. The support rod 27 is threadedly connected to the second screw 31. When the third motor 30 is started, the second screw 31 rotates and drives the support rod 27 to slide along the equipment platform 1, thereby adjusting the lateral position of the feeding platform 28 and the conveying unit 29 to meet the material picking needs of the robot arm 7.

[0043] The specific transmission structure of the conveying unit 29 is as follows: It includes two conveying rollers 32 rotatably connected to the top of the feeding platform 28, with a conveyor belt 33 sleeved between the two conveying rollers 32. The digital tubes are placed on the conveyor belt, and conveying is achieved by the rotation of the conveyor belt 33. A driven grooved wheel 34 is fixedly connected to the outer side of the roller shaft of one of the conveying rollers 32. A fourth motor 35 is fixedly connected to the top of the feeding platform 28, and an active dial 36 is fixedly connected to the output shaft of the fourth motor 35. The active dial 36 and the driven grooved wheel 34 cooperate with each other. When the fourth motor 35 starts, the active dial 36 drives the driven grooved wheel 34 to rotate, thereby driving the conveying rollers 32 and the conveyor belt 33 to rotate intermittently, realizing the stable conveying of the digital tubes. The conveying of the digital tubes to the designated position can greatly increase the splicing efficiency.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
