Description

Technical Field

[0001] This utility model specifically relates to a centering device for the base of an LCD TV. Background Technology

[0002] The production process of LCD TVs is a complex process involving multiple stages, processes, high precision, and technical requirements. The main processes include the preparation, processing, and assembly of LCD TV components, as well as the debugging and testing of finished LCD TVs. It can be seen that the production process of LCD TVs is not completed on a single machine or equipment. During the production process, processes such as uprighting, flipping, and transferring are inevitable. A base is a component used when transferring an LCD TV. Its main purpose is to protect the LCD TV during the transfer. It is usually made of EPE pearl cotton or high-density foam and has functions such as anti-collision, cushioning, pressure resistance, and plasticity. It can disperse the impact force during the transportation of the LCD TV and prevent the LCD screen from being damaged by vibration or external collision.

[0003] Currently, when LCD TVs are transferred and transported on the production line, the base tray cannot be quickly aligned, and the low alignment efficiency affects the normal transfer and transport of LCD TVs. At the same time, traditional base tray alignment devices only have alignment functions and cannot adjust the height of the base tray according to the needs of the production line, making them inflexible and less adaptable.

[0004] Therefore, it is necessary to invent a centering device for the base of an LCD TV to solve the above problems. Utility Model Content

[0005] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a centering device for LCD TV base supports. By incorporating a servo module, two clamping plates can synchronously move closer or further apart. With the assistance of the limiting baffle, the base support can quickly complete centering on the placement platform. The entire process is simple, fast, and highly efficient. Simultaneously, the support frame can be adjusted in height above the base frame under the drive of an electric cylinder, adapting to the needs of different LCD TV production lines. It is relatively flexible, highly adaptable, and beneficial for the transfer and transportation of LCD TVs.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a centering device for a liquid crystal television base, comprising a support frame, wherein a plurality of placement platforms for supporting the base are installed on the top of the support frame; Two baffles are respectively set on the rear side of the two middle placement platforms. Each baffle is equipped with a drive mechanism on the rear side to drive the baffle to move horizontally so as to block the rear side of the base. Two servo modules are respectively installed on the top of the left and right ends of the support frame. Each servo module is equipped with a clamping plate that can move along the length of the support frame to clamp the left and right sides of the base. A base frame is installed at the bottom of the support frame, and a lifting assembly is installed at the top of the base frame to drive the support frame to move horizontally and adjust the height of the support frame.

[0007] Preferably, there are four placement platforms, arranged symmetrically in pairs about the center of the support frame 1, and the two baffles equipped with the drive mechanism are widened.

Detailed Implementation

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figure 1-5 The aforementioned LCD TV base centering device includes a support frame 1, and a plurality of placement platforms 2 for supporting the base are installed on the top of the support frame 1. Two baffles 3 are respectively set on the rear side of the two placement platforms 2 located in the middle. Each baffle 3 is equipped with a drive mechanism 4 on the rear side to drive the baffle 3 to move horizontally so as to block the rear side of the base. Two servo modules 5 are respectively installed on the top of the left and right ends of the support frame 1. Each servo module 5 is equipped with a clamping plate 6 that can move along the length of the support frame 1 to clamp the left and right sides of the base. A base frame 7 is installed at the bottom of the support frame 1, and a lifting assembly 8 is installed at the top of the base frame 7 for driving the support frame 1 to move horizontally, thereby adjusting the height of the support frame 1. Each of the drive mechanisms 4 includes two slide rails 41 arranged side by side on the rear side of the baffle 3, a slider 42 sleeved on the outside of the slide rails 41, a decorative plate 43 connected to the slide rails 41 through the two sliders 42, a push plate 44 connected to the rear side of the baffle 3, and a cylinder 45 installed at the bottom of the decorative plate 43 and whose output end is connected to the push plate 44. The lifting assembly 8 includes four guide rods 81 installed at the bottom of the support frame 1. Each guide rod 81 is fitted with a positioning block 82 on its outer side, and a positioning rod 83 is installed between every two positioning blocks 82 that are aligned front to back or left to right. It also includes a top plate 84 installed in the middle of the support frame 1, and an electric cylinder 85 installed on the base frame 7 with its output end connected to the bottom of the top plate 84.

[0017] In one embodiment, four placement platforms 2 are provided, symmetrically distributed about the center of the support frame 1 in pairs, and the two placement platforms 2 equipped with the drive mechanism 4 are widened to accommodate the width of the baffle 3, so that the baffle 3 can assist the clamping plate 6 in quickly centering the base.

[0018] In one embodiment, each of the drive mechanisms 4 further includes a support plate 46 installed on the bottom of the decoration. The front end of the support plate 46 is connected to the bottom of the support frame 1 to support the decoration plate 43, so that the baffle 3 and the slide rail 41 can be moved horizontally along the height direction of the decoration plate 43 to complete the raising or lowering of the baffle 3.

[0019] In one embodiment, the bottom end of each guide rod 81 passes through the positioning block 82 and the base frame 7 in sequence. Each positioning block 82 is connected to the top of the base frame 7. When the support frame 1 is lifted by the output end of the electric cylinder 85 or falls back under gravity, the four guide rods will move vertically along the through holes on the positioning block 82 and the base frame 7, thereby ensuring the stability of the support frame 1 when it is raised or lowered.

[0020] The specific implementation method is as follows: When this utility model is in use, the LCD TV is transported to one side of the centering device by an external connecting roller conveyor, while the base is picked up by an external base suction device and placed on the top of the placement platform 2. Then, the operator starts the servo modules 5 on both sides, which convert the rotational motion of the internal servo motor into linear motion to realize the horizontal movement of the clamping plates 6. That is, under the drive of the servo module 5, the two clamping plates 6 will move synchronously toward the middle of the support frame 1, so that the base is in the middle of the support frame 1, completing the centering. During this process, the output end of the cylinder 45 will extend upward, thereby pushing the push plate 44 upward, further allowing the slide rail 41 to move upward along the height direction of the slider 42, and then driving the baffle 3 to move upward, so that when the base is clamped by the clamping plates 6 on the left and right, its rear side is blocked, preventing the base from tilting during centering and ensuring the accuracy of the base centering. Meanwhile, staff can adjust the laying height of support frame 1 according to the needs of the production line. Specifically, by starting the electric cylinder 85 and controlling the output end of the electric cylinder 85 to move upward, the top plate 84 can be lifted upward. At this time, the four guide rods 81 will move vertically upward in sync, so that the entire support frame 1 can move upward in sync and stably, thus increasing the laying height of support frame 1. Conversely, by controlling the output end of the electric cylinder 85 to move downward, the top plate 84 can fall downward. At this time, the four guide rods 81 will move vertically downward in sync, thus decreasing the laying height of support frame 1. This allows the height of support frame 1 above the base frame 7 to be freely changed according to usage requirements. This implementation method specifically solves the problem in the prior art that when LCD TVs are transferred and transported on the production line, the base tray cannot be accurately aligned, requiring manual assistance to place the base tray, which affects the normal transfer and transport of LCD TVs; at the same time, traditional base tray alignment devices only have an alignment function and cannot adjust the height of the base tray according to the needs of the production line, making them inflexible and having low adaptability.

[0021] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used above are only some embodiments recorded in this utility model. Obviously, those skilled in the art can obtain other drawings based on these drawings.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
