Description

Technical Field

[0001] This utility model relates to the field of clamping and positioning technology, and in particular to a rapid clamping and positioning device for assembling multi-specification screens for displays. Background Technology

[0002] In the industrial assembly process of monitors, the screen, as the core display component, directly determines the display effect and structural stability of the final product through its assembly precision. The screen assembly process requires the initial positioning of the screen using a clamping and positioning device to prevent displacement during assembly. Only then can subsequent processes such as backlight module bonding, bezel fastening, and driver board welding be completed sequentially. Therefore, the reliability and adaptability of the clamping and positioning device become key factors affecting assembly efficiency and product quality. With the iteration of display technology and the diversification of market demands, monitor screen specifications exhibit significant diversity, covering different sizes such as 19 inches, 27 inches, and 32 inches. This diversity places extremely high demands on the flexibility and adaptability of production lines. The clamping and positioning device must quickly respond to the positioning needs of screens of different sizes to ensure the continuous operation of the production line.

[0003] Currently, the demand for multi-specification adaptability of clamping and positioning devices in the display assembly industry is increasingly urgent. The core reason is that if the device cannot flexibly adapt to different screen sizes, the production line needs to spend a significant amount of time debugging equipment or adjusting components when switching product models, leading to increased downtime and directly reducing production efficiency. At the same time, equipping multiple dedicated positioning devices to adapt to multiple screen sizes would significantly increase the procurement cost of production equipment and the space occupied in the workshop and warehouse, contradicting the modern manufacturing philosophy of "high efficiency, flexibility, and low cost." Furthermore, frequent equipment adjustments or component replacements may introduce installation errors, affecting screen positioning accuracy and leading to quality problems such as misalignment and incomplete frame fastening. Therefore, this application proposes a rapid clamping and positioning device for assembling multi-specification screens to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a rapid clamping and positioning device for assembling multi-specification screens for displays, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-specification screen quick clamping and positioning device for assembling displays includes a carrier plate. A first scale is fixedly embedded on the upper surface of the carrier plate. An adjustment structure is movably installed inside the carrier plate. The adjustment structure consists of a lead screw, handles, and moving blocks. Two handles are symmetrically fixedly installed at both ends of the lead screw. Two moving blocks are symmetrically installed on the lead screw. A scale structure is fixedly inserted into each of the two moving blocks. The scale structures are located above the carrier plate. The scale structure includes a second scale and a moving plate. The moving plate is fixedly installed on the inner end of the second scale. Two L-shaped limiting structures are symmetrically installed on the second scale. The L-shaped limiting structures consist of an L-shaped base plate and an L-shaped rubber pad. The L-shaped rubber pad is fixedly installed on the inner wall of the L-shaped base plate.

[0006] Preferably, the carrier plate has a guide rail groove that runs through the top and bottom of the carrier plate, and two through holes are symmetrically opened at both ends of the carrier plate, and the through holes are connected to the guide rail groove.

[0007] Preferably, the lead screw on the adjustment structure is rotatably mounted in the guide rail groove and two through holes, and the handle is located on the outside of the carrier plate.

[0008] Preferably, the movable block on the adjustment structure is movably mounted in the guide rail groove opened on the carrier plate, and the movable block is provided with a threaded hole, and the movable block is mounted on the lead screw through the threaded hole.

[0009] Preferably, the second scale on the scale structure is fixedly inserted into the movable block, the inner end of the movable scale plate is flush with the inner wall of one side of the L-shaped rubber pad, and the movable scale plate is located directly above the first scale.

[0010] Preferably, the L-shaped limiting structure contacts the upper end face of the carrier plate, and a through groove is provided on the L-shaped base plate of the L-shaped limiting structure. The L-shaped base plate is sleeved on the second scale through the through groove, and the second scale is fixedly connected to the second scale by bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting a first scale and an adjustment structure consisting of a lead screw, a handle, and a moving block on the carrier plate, and a scale structure consisting of a second scale and a moving plate on the moving block, and an L-shaped limiting structure consisting of an L-shaped base plate and an L-shaped rubber pad on the second scale, rotating the handle drives the lead screw to rotate, thereby causing the two moving blocks to move synchronously closer or further apart along the guide rail groove. During the movement of the moving blocks, the scale structure on them will move synchronously. Combined with the first scale on the carrier plate, the distance between the two sets of scale structures can be adjusted to adapt to the horizontal size of different screens. At the same time, the L-shaped limiting structure can move freely along the second scale. By sliding and using the scale reference of the second scale, the distance between the two L-shaped limiting structures on the same scale structure can be adjusted to adapt to the vertical dimensions of different screens. Through dual adjustment in both horizontal and vertical dimensions, the device can achieve positioning of screens of various specifications, effectively shortening the debugging time when switching product models on the production line and significantly improving assembly efficiency. In addition, there is no need to equip multiple sets of dedicated positioning devices for screens of different specifications, which greatly reduces equipment procurement costs and workshop storage space occupation. At the same time, it reduces installation errors caused by frequent component replacement or equipment debugging, thereby reducing the probability of assembly quality problems such as misalignment and loose frame fastening.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a multi-specification screen quick clamping and positioning device for assembling displays includes a carrier plate 1. A first scale 2 is fixedly embedded on the upper surface of the carrier plate 1. An adjustment structure 3 is movably installed inside the carrier plate 1. The adjustment structure 3 consists of a lead screw 8, handles 9, and moving blocks 10. There are two handles 9 symmetrically fixedly installed at both ends of the lead screw 8. There are two moving blocks 10 symmetrically installed on the lead screw 8. A scale structure 4 is fixedly inserted into each of the two moving blocks 10. The scale structure 4 is located above the carrier plate 1. The scale structure 4 includes a second scale 12 and a moving block 10. The movable scale plate 13 is fixedly installed on the inner end of the second scale 12. Two L-shaped limiting structures 5 are symmetrically installed on the second scale 12. The L-shaped limiting structure 5 consists of an L-shaped base plate 14 and an L-shaped rubber pad 15. The L-shaped rubber pad 15 is fixedly installed on the inner wall of the L-shaped base plate 14. By setting a first scale 2 on the carrier plate 1 and an adjustment structure 3 consisting of a lead screw 8, a handle 9, and a moving block 10, and setting a scale structure 4 consisting of a second scale 12 and a movable scale plate 13 on the moving block 10, and setting an L-shaped limit structure 5 on the second scale 12, the adjustment structure 5 is further modified by the L-shaped limit structure 5. The L-shaped limiting structure 5, composed of substrate 14 and L-shaped rubber pad 15, allows the screw 8 to rotate when the handle 9 is turned, thereby causing two moving blocks 10 to move synchronously closer or further away along the guide rail groove 6. During the movement of the moving blocks 10, the scale structure 4 on them will move synchronously. Combined with the first scale 2 on the carrier plate 1, the distance between the two sets of scale structures 4 can be adjusted to adapt to the horizontal size of different screens. At the same time, the L-shaped limiting structure 5 can slide freely along the second scale 12. With the scale reference of the second scale 12, the same scale structure 4 can be adjusted. The two L-shaped limiting structures are adjusted at a distance of 5 to accommodate the vertical dimensions of different screens. Through dual adjustment in both horizontal and vertical dimensions, the device can achieve clamping and positioning of screens of various specifications, effectively shortening the debugging time when switching product models on the production line and significantly improving assembly efficiency. In addition, there is no need to equip multiple sets of dedicated positioning devices for screens of different specifications, which greatly reduces equipment procurement costs and workshop storage space occupation. At the same time, it reduces installation errors caused by frequent component replacement or equipment debugging, thereby reducing the probability of assembly quality problems such as misalignment and loose frame fastening.

[0016] Specifically, a guide rail groove 6 is provided on the carrier plate 1, which runs vertically through the carrier plate 1. Two through holes 7 are symmetrically provided at both ends of the carrier plate 1, and the through holes 7 are connected to the guide rail groove 6. The lead screw 8 on the adjusting structure 3 is rotatably installed in the guide rail groove 6 and the two through holes 7. The handle 9 is located on the outside of the carrier plate 1. The moving block 10 on the adjusting structure 3 is movably installed in the guide rail groove 6 on the carrier plate 1. The moving block 10 is provided with a threaded hole 11, and the moving block 10 is installed on the lead screw 8 through the threaded hole 11. The second scale 12 on the scale structure 4 is fixedly inserted into the moving block 10. The inner end of the moving scale plate 13 is flush with the inner wall of one side of the L-shaped rubber pad 15, and the moving scale plate 13 is located directly above the first scale 2. The L-shaped limiting structure 5 is connected to the upper end of the carrier plate 1. The L-shaped substrate 14 on the L-shaped limiting structure 5 has a through groove 16. The L-shaped substrate 14 is fitted onto the second scale 12 through the through groove 16, and the second scale 12 is fixedly connected to the second scale 12 by bolts. The carrier plate 1 is installed on the conveying equipment of the production line. When using this clamping positioning device to position the screen during the display assembly process, the screen must first be placed stably on the upper end of the carrier plate 1 and between the four L-shaped limiting structures 5. The inner walls of the L-shaped rubber pads 15 in the four L-shaped limiting structures 5 are tightly fitted to the outer sides of the four corners of the screen. With the contact and limiting between the L-shaped rubber pads 15 and the screen surface, and with the structural support of the L-shaped substrate 14, the screen is accurately positioned to prevent the screen from shifting in subsequent assembly processes.

[0017] When the production line needs to switch product models, the positions of the four L-shaped limiting structures 5 need to be adjusted according to the size of the new screen. The specific steps are as follows: First, loosen the bolts used for fixing on the L-shaped base plate 14 so that the bolts are not in contact with the second scale 12. At this time, the fixing of the L-shaped limiting structure 5 is released, and the L-shaped limiting structure 5 can slide freely along the second scale 12. Referring to the scale of the second scale 12, push the two L-shaped limiting structures 5 on the same scale structure 4 to move along the second scale 12 until the distance between the two L-shaped limiting structures 5 matches the longitudinal size of the new screen (the L-shaped limiting structures 5 on the two second scale 12 need to be aligned to avoid misalignment and ensure that the screen can be smoothly placed between the four L-shaped limiting structures 5). Then tighten the bolts so that the bolts abut against the screen. On the second scale 12, the L-shaped substrate 14 is fixed to the second scale 12. Then, the handle 9 is turned to drive the lead screw 8 to rotate in the guide rail groove 6 and the through hole 7. When the lead screw 8 rotates, it will drive the two moving blocks 10 to move closer or further away from each other along the guide rail groove 6. During the movement of the moving blocks 10, the scale structure 4 on them will move synchronously. Since the inner end of the moving plate 13 is flush with the inner wall of one side of the L-shaped rubber pad 15, the operator can observe the scale of the moving plate 13 corresponding to the first scale 2 on the carrier plate 1 and adjust the spacing of the four L-shaped limiting structures 5 on the two sets of scale structures 4 to adapt to the horizontal size of the new screen. After the spacing is adjusted to the right position, the handle 9 is stopped. At this time, the position of the four L-shaped limiting structures 5 is completely adapted to the new screen size, and subsequent screen placement and positioning operations can be carried out.

[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
