Description

Technical Field

[0001] The utility model belongs to the technical field of LCD display screens, and in particular relates to a transfer rack for producing LCD display screens. Background Art

[0002] LCD display, or liquid crystal display, is a flat-panel display technology widely used in electronic devices. It is composed of many liquid crystal molecules, which can be controlled by electric fields to change the degree of light transmittance, thereby realizing image display. LCD display has the advantages of low power consumption, wide viewing angle, and fast response speed. It is widely used in various electronic devices such as televisions, computer monitors, mobile phones, and tablet computers. During the production process of LCD displays, when they need to be sent from one process to the next, they need to be transported using a transfer rack.

[0003] In the prior art, there is a layered transfer rack for display screen production with a patent announcement number of CN218287853U. The above patent includes a base, a device rod and a plurality of placement mechanisms. The device rod is vertically fixedly connected to the upper surface of the base, and the plurality of placement mechanisms are evenly spaced on the outer surface of the device rod along the length direction of the device rod. The device is provided with a device rod and a plurality of placement mechanisms. The device arranges the plurality of placement mechanisms on the outer surface of the device rod. When loading a display, after placing a display in a placement mechanism, the placement mechanism can be rotated. At this time, the next display can be placed in a placement mechanism below. The loading of the display can be completed by repeating this process. Moreover, since the device installs the plurality of placement mechanisms on a device rod together, the device rod serves as a support, and the transfer rack will not fall over during transportation. However, there are still the following deficiencies in actual use: from a practical point of view, the device is provided with a plurality of placement mechanisms in layers, but the plurality of placement mechanisms are vertically designed. Due to the high height of the placement tray at the highest point, the staff need to climb to a high height to place the display screen during transportation, which not only increases the labor intensity but also reduces the work efficiency.

[0004] Therefore, a transfer rack for LCD display production is needed to solve the problem in the prior art that the vertical layered design of the placement tray makes it inconvenient for workers to place the display screen. Utility Model Content

[0005] The purpose of the utility model is to provide a transfer rack for producing LCD display screens to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transfer frame for LCD display screen production, comprising a base plate, a plurality of pulleys fixedly connected to the bottom of the base plate, two support plates fixedly connected to the top of the base plate, a rotating shaft rotatably connected between the two support plates, a driving roller fixedly connected to the outer wall of the rotating shaft, a worm gear fixedly connected to one side of the rotating shaft passing through the support plate, a mounting frame fixedly connected to the outer side of one of the support plates, a worm rotatably connected to the inner wall of the mounting frame, a servo motor corresponding to the worm gear installed on the top of the mounting frame, a plurality of evenly distributed convex frames fixedly connected to the outer wall of the driving roller, a plurality of convex frames are rotatably mounted with pipe sleeves on the outer walls, a plurality of pipe sleeves are fixedly connected to the bottom of each connecting column, a fixing mechanism is provided at the bottom of each connecting column, and a hand push rod is fixedly connected to the top of the base plate near the rear end.

[0007] It should be noted in the solution that the plurality of pulleys are all universal self-locking wheels.

[0008] It is further worth noting that the worm is meshed with the worm wheel.

[0009] It should be further explained that the output end of the servo motor passes through the top of the mounting frame and is fixedly connected to the worm.

[0010] As a preferred embodiment, the fixing mechanism includes a placement frame fixedly connected to the bottom of the connecting column, a buffer pad is fixedly connected to the upper surface of the bottom of the placement frame, a plurality of threaded rods are rotatably connected to the top of the placement frame, a plurality of the threaded rods are fixedly connected to the tops of the plurality of rotating plates, a plurality of the threaded rods are installed with rotating seats at the bottoms, and a plurality of the rotating seats are fixedly connected to the bottoms of the plurality of pressure plates.

[0011] As a preferred implementation, a plurality of thread grooves corresponding to the threaded rods are formed on the top of the placement frame.

[0012] As a preferred implementation, an anti-slip sleeve is fixedly connected to the outer wall of the hand push rod.

[0013] Compared with the prior art, the utility model provides a transfer rack for LCD display production, which has at least the following beneficial effects:

[0014] (1) By setting a driving roller and a plurality of convex frames in coordination, a fixing mechanism is set at the bottom of each of the convex frames. The driving roller is powered by a worm gear and a worm, which drives the driving roller to rotate, so that the plurality of fixing mechanisms can rotate in a circle to achieve a change in height position, making it easier for workers to place the display screen inside the fixing mechanism, thereby reducing the labor intensity of the workers and improving the transportation efficiency.

[0015] (2) By setting up a fixing mechanism, the display screen is placed inside the placement frame, and the rotating plate drives the threaded rod to rotate. The threaded rod drives the pressure plate to descend while rotating, thereby clamping and fixing the display screen to prevent the display screen from falling during transportation, thereby improving the safety of the device.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-4 The utility model provides a transfer rack for producing LCD display screens, including a bottom plate 1, a plurality of pulleys 2 are fixedly connected to the bottom of the bottom plate 1, two support plates 3 are fixedly connected to the top of the bottom plate 1, a rotating shaft 4 is rotatably connected between the two support plates 3, a driving roller 5 is fixedly connected to the outer wall of the rotating shaft 4, a worm gear 6 is fixedly connected to one side of the rotating shaft 4 penetrating through the support plates 3, a mounting frame 7 is fixedly connected to the outer side of one of the support plates 3, a worm 8 is rotatably connected to the inner wall of the mounting frame 7, a servo motor 9 corresponding to the worm 8 is installed on the top of the mounting frame 7, a plurality of evenly distributed convex frames 10 are fixedly connected to the outer wall of the driving roller 5, a plurality of convex frames 10 are rotatably installed with pipe sleeves 11 on the outer walls, a plurality of pipe sleeves 11 are fixedly connected to the bottoms of the plurality of pipe sleeves 11, a fixing mechanism 13 is arranged at the bottoms of the plurality of connecting columns 12, and a hand push rod 14 is fixedly connected to the top of the bottom plate 1 near the rear end.

[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that the multiple pulleys 2 are all universal self-locking wheels, so that the pulleys 2 can slide and self-lock flexibly, which is convenient for the staff to move and position the device.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the worm 8 is meshed with the worm wheel 6 to ensure that the worm 8 can drive the worm wheel 6 to rotate. At the same time, the transmission of the worm wheel 6 and the worm 8 has a self-locking characteristic, which can effectively prevent reversal and increase the safety of the device.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the output end of the servo motor 9 passes through the top of the mounting frame 7 and is fixedly connected to the worm 8, ensuring that the servo motor 9 can drive the worm 8 to rotate smoothly, thereby providing driving force for the rotation of the driving roller 5, so that the multiple fixing mechanisms 13 can rotate in a circle to achieve changes in height positions.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that an anti-slip sleeve is fixedly connected to the outer wall of the hand push rod 14 to increase the friction between the outer wall of the hand push rod 14 and the palm, making it easier for the staff to grasp and further reducing the labor intensity of the staff.

[0027] According to the above working process, it can be known that: by setting the driving roller 5 and the multiple convex frames 10 to cooperate with each other, the bottom of the multiple convex frames 10 are provided with a fixing mechanism 13, and the driving roller 5 is powered by the worm gear 6 and the worm 8 to drive the driving roller 5 to rotate, so that the multiple fixing mechanisms 13 can rotate in a circle to achieve the change of height position, which is convenient for the staff to place the display screen inside the fixing mechanism 13, reduces the labor intensity of the staff, and improves the transportation efficiency.

[0028] Further as Figure 4 As shown, it is worth explaining in detail that the fixing mechanism 13 includes a placement frame 1301 fixedly connected to the bottom of the connecting column 12, a buffer pad 1302 is fixedly connected to the upper surface of the bottom of the placement frame 1301, a plurality of threaded rods 1303 are rotatably connected to the top of the placement frame 1301, a plurality of threaded rods 1303 are fixedly connected to the top of each of the rotating plates 1304, a plurality of threaded rods 1303 are installed with a rotating seat 1305 at the bottom, and a plurality of rotating seats 1305 are fixedly connected to the bottom of each of the pressing plates 1306. By setting the fixing mechanism 13, the display screen is clamped and fixed to avoid the display screen from falling during transportation, thereby improving the safety of the device.

[0029] Further as Figure 4As shown, it is worth explaining in detail that a plurality of thread grooves corresponding to the threaded rod 1303 are opened on the top of the placement frame 1301. The thread grooves cooperate with the threaded rod 1303 so that the threaded rod 1303 can be lifted and lowered during the rotation process, providing driving force for the lifting and lowering of the pressure plate 1306.

[0030] This solution has the following working process: in actual use, the display screen to be transported is placed inside the placement frame 1301, and the rotating plate 1304 is rotated to drive the threaded rod 1303 to rotate. The threaded rod 1303 drives the pressure plate 1306 to descend while rotating, so as to clamp and fix the display screen. Then, the servo motor 9 is turned on to drive the worm 8 to rotate, so that the worm wheel 6 rotates accordingly, thereby causing the rotating shaft 4 to drive the driving roller 5 to rotate, and drive multiple placement frames 1301 to rotate in a circle, realizing the change of the height position, so that the staff can place the display screen inside the placement frame 1301.

[0031] In summary: by setting a driving roller 5 and cooperating with multiple convex frames 10, a fixing mechanism 13 is set at the bottom of the multiple convex frames 10, and the driving roller 5 is powered by the worm gear 6 and the worm 8, which drives the driving roller 5 to rotate, so that the multiple fixing mechanisms 13 can rotate in a circle to achieve the change of high and low positions, which is convenient for the staff to place the display screen inside the fixing mechanism 13, reduces the labor intensity of the staff, and improves the transportation efficiency; by setting the fixing mechanism 13, the display screen is clamped and fixed to avoid the display screen from falling during transportation, thereby improving the safety of the device.
