Description

Technical Field

[0001] The utility model relates to the technical field of LED display production, in particular to a flipping fixture for LED display production. Background Art

[0002] A flipping fixture for LED display production is a special device, which is mainly used to conveniently flip and position each component of the LED display during the assembly process. This fixture is usually designed to adapt to the size and shape of the components and ensure efficient and safe operation on the production line.

[0003] Traditional flipping fixtures are often fixed on the flipping mechanism and cannot quickly adapt to changes in production requirements (different product specifications and production needs). On this basis, more time is required to replace the fixture, resulting in an increase in the downtime of the production line and a reduction in production efficiency.

[0004] Secondly, the traditional flipping fixture does not have an automatic positioning function. A flipping fixture without a positioning function may cause alignment problems during the assembly of the display components, affecting the display effect and the final performance of the device. Moreover, manually placing and adjusting the components is more prone to errors, which may increase the production defect rate.

[0005] Finally, the width of the previous fixtures is often fixed and cannot flexibly adapt to products of different sizes. It may be necessary to design multiple fixtures for different specifications of displays, which limits the flexibility and diversity of the production line and cannot adapt to the manufacture of some special specifications of products.

Detailed Description of the Embodiment

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0026] Please refer to Figures 1-5 , a flipping fixture for LED display production, comprising a main body 1, a quick replacement mechanism, a positioning mechanism and a flipping clamping mechanism. The quick replacement mechanism includes a connecting shaft 2, a first spring 3, an extrusion sleeve 4, an insertion rod 5, a rotating frame 6 and a locking sleeve 7. The connecting shaft 2 is installed inside the main body 1 and is rotatably connected to the main body 1. The first spring 3 is fixedly installed inside the connecting shaft 2, and both ends of the first spring are fixedly connected to the connecting shaft 2 and the extrusion sleeve 4 respectively. The extrusion sleeve 4 is installed inside the connecting shaft 2 and is slidably connected to the connecting shaft 2. The insertion rod 5 is detachably connected to the connecting shaft 2. The rotating frame 6 is rotatably connected to the locking sleeve 7. The locking sleeve 7 is in threaded engagement with the insertion rod 5. The positioning mechanism includes a positioning frame 8, a rubber shaft 9, a sliding base 10, a second spring 11 and a through rod 12. The rubber shaft 9 is installed on the sliding base 10 and is rotatably connected to the sliding base 10. The second spring 11 is installed inside the positioning frame 8 and both ends are fixedly connected to the positioning frame 8 and the sliding base 10 respectively. The through rod 12 is fixedly installed inside the positioning frame 8 and passes through the sliding base 10.

[0027] In this embodiment, the quick replacement mechanism includes a connecting shaft 2, a first spring 3, an extrusion sleeve 4, an insertion rod 5, a rotating frame 6 and a locking sleeve 7. During use, insert the insertion rod 5 into the inside of the connecting shaft 2. When the block 22 on the insertion rod 5 enters the connecting shaft 2 through the positioning hole 20 on the connecting shaft 2, at this time, the block 22 contacts the extrusion sleeve 4, pushing the insertion rod 5, and the block 22 starts to squeeze the extrusion sleeve 4, thereby compressing the first spring 3. When the block 22 completely enters the inside of the connecting shaft 2, the first spring 3 pushes the extrusion sleeve 4 to always contact the block 22. Rotate the insertion rod 5, and the compressed first spring 3 drives the extrusion sleeve 4 to push the block 22 into the clamping hole 21. At this time, rotate the locking sleeve 7 that is in threaded engagement with the insertion rod 5. While rotating the locking sleeve 7, the rotating frame 6 slowly approaches the connecting shaft 2. During the process of rotating the locking sleeve 7, then rotate the rotating frame 6. The connecting disk 23 on the rotating frame 6 rotates inside the rotating chute 24 in the locking sleeve 7, align the rotating frame 6 with the positioning hole 20, and then continue to rotate. When the rotating frame 6 completely enters the positioning hole 20, at this time, the locking sleeve 7 is in close contact with the connecting shaft 2. At this time, the insertion rod 5 is completely fixed to the connecting shaft 2 after being subjected to the cooperation of the block 22 and the clamping hole 21 and the force exerted by the locking sleeve 7 on the connecting shaft 2, completing the installation. If it needs to be disassembled, perform the above operations in reverse.

[0028] In this embodiment, the positioning mechanism includes a positioning frame 8, a rubber shaft 9, a sliding base 10, a second spring 11, and a through rod 12. During use, the display screen to be processed is placed into the positioning frame 8 under the clamping of the rubber shaft 9. During this process, since the rubber shaft 9 itself has elasticity, the display screen can be directly placed in. If the display screen is too large, at this time, the sliding base 10 is pressed to compress the second spring 11, and the limiting rod 30 on the movable base slides in the limiting chute 29 inside the positioning frame 8 and also slides on the through rod 12 in the positioning frame 8. When the display screen is taken out, the compressed second spring 11 releases its elastic force, causing the sliding base 10 to slide in the positioning frame 8, resetting the rubber shaft 9, and waiting for the next use.

[0029] In this embodiment, the flipping and clamping mechanism includes a flipping motor 13, a fixed frame 14, a micro motor 15, a lead screw 16, and a clamping plate 17. During use, first, adjust the position of the positioning frame 8. At this time, hold the wing nut 27 on the short rod 26, so that the positioning frame 8 rotates in the positioning chute 25. When the position is adjusted to fit the size of the display screen, then twist the wing nut 27 to fix the positioning frame 8. When the display screen enters below the clamping plate 17 through the rubber shaft 9, the display screen first contacts the rubber soft pad 28, and then the micro motor 15 is driven, and the lead screw 16 rotates accordingly, driving the clamping plate 17 to slide up and down in the positioning frame 8 until the rubber soft pad 28 on the clamping plate 17 contacts the display screen to complete the clamping. At this time, the flipping motor 13 installed on the supporting plate 19 of the main body 1 is driven to drive the connecting shaft 2 to rotate inside the roller bearing 18. Embodiment 2

[0030] In summary, when in use, first insert the insertion rod 5 into the interior of the connecting shaft 2. When the block 22 on the insertion rod 5 enters the connecting shaft 2 through the positioning hole 20 on the connecting shaft 2, the block 22 at this time contacts the extrusion sleeve 4, pushing the insertion rod 5. The block 22 begins to squeeze the extrusion sleeve 4, thereby compressing the first spring 3. When the block 22 completely enters the interior of the connecting shaft 2, the first spring 3 pushes the extrusion sleeve 4 to always contact the block 22. The insertion rod 5 is rotated, and the squeezed first spring 3 drives the extrusion sleeve 4 to push the block 22 into the card hole 21. At this time, the locking sleeve 7 that is threadedly engaged with the insertion rod 5 is rotated. At the same time, the rotating frame 6 slowly approaches the connecting shaft 2. In the process of rotating the locking sleeve 7, the rotating frame 6 is then rotated. The connecting plate 23 on the rotating frame 6 rotates inside the rotating slide groove 24 in the locking sleeve 7, aligning the rotating frame 6 with the positioning hole 20, and then continuing to rotate. When the rotating frame 6 completely enters the positioning hole 20, the locking sleeve 7 is in close contact with the connecting shaft 2. At this time, the insertion rod 5 is completely fixed to the connecting shaft 2 by the cooperation between the block 22 and the card hole 21 and the force applied by the locking sleeve 7 to the connecting shaft 2, completing the installation. To disassemble, follow the above-mentioned reverse operation and then adjust the position of the positioning frame 8. When the screen is too large, the sliding base 10 is compressed by the pressure of the second spring 11, and the limiting rod 30 on the movable base slides in the limiting groove 29 inside the positioning frame 8 and slides on the through rod 12 in the positioning frame 8. After the display screen is taken out, the compressed second spring 11 releases its elastic force, causing the sliding base 10 to slide in the positioning frame 8, so that the rubber shaft 9 is reset and waits for the next use. When the display screen passes through the rubber shaft 9 and enters under the clamping plate 17, the display screen first contacts the rubber pad 28, and then the micro motor 15 is driven, and the lead screw 16 rotates accordingly, driving the clamping plate 17 to slide up and down in the positioning frame 8 until the rubber pad 28 on the clamping plate 17 contacts the display screen, completing the clamping. At this time, the flip motor 13 installed on the supporting plate 19 of the main body 1 is driven to drive the connecting shaft 2 to rotate inside the roller bearing 18.
